Factores asociados al tratamiento no exitoso para tuberculosis en pacientes previamente tratados en Cali, Colombia, en el periodo 2015-2019 / Factors associated with unsuccessful treatment outcome for tuberculosis in previously treated patients in Cali, Colombia, during the period 2015-2019

Introducción. Las tasas de éxito del tratamiento de la tuberculosis continúan siendo subóptimas. Objetivo. Identificar los factores asociados al tratamiento no exitoso para tuberculosis en pacientes con antecedentes de tratamiento para la tuberculosis. Materiales y métodos. Se realizó un estudio observacional retrospectivo, analítico, de cohorte de pacientes que reingresaron a un programa de micobacterias en Cali, Colombia. Se incluyeron mayores de 15 años con tuberculosis pulmonar entre el 2015 y el 2019 con antecedentes de tratamiento para la tuberculosis. Se excluyeron los pacientes con tuberculosis resistente. Resultados. Ingresaron 605 pacientes con antecedentes de tratamiento, 60 % por tratamiento inconcluso y 40 % por recaída. En comparación con los pacientes que reingresaron por recaída (ORa= 2,34; IC=1,62-3,38), las variables que explicaron de manera independiente el no tener éxito con el tratamiento para la tuberculosis al egreso fueron: estar en situación de calle (ORa = 2,45; IC = 1,54-3,89), ser farmacodependiente (ORa = 1,95; IC=1,24-3,05), tener coinfección tuberculosis/VIH (ORa = 1,69; IC =1,00- 2,86) o diabetes (ORa =1,89; IC=1,29-2,77), y el incumplimiento de un tratamiento previo por pérdida de seguimiento, abandono u otras causas. Las variables programáticas que favorecieron el éxito del tratamiento fueron la asesoría de la prueba voluntaria de VIH (p < 0,001) y la realización de la prueba de VIH (p < 0,001). Conclusión. Estar en situación de calle, ser farmacodependiente, tener coinfección de tuberculosis y VIH, o diabetes, así como el incumplimiento del tratamiento previo por pérdida del seguimiento, abandono o fracaso del mismo, dificultaron el éxito del tratamiento antituberculoso. En la primera atención al reingreso de los pacientes con tuberculosis se deben identificar y abordar estas características.

Introduction. The success rates in the treatment of tuberculosis are suboptimal. Objective. To identify associated factors with the lack of success of antituberculosis treatment in patients with a tuberculosis treatment history. Materials and methods. We performed a retrospective, analytical, observational, and cohort study of patients reentering the Mycobacterium program in Cali, Colombia. We included patients over 15 years old with pulmonary tuberculosis between 2015 and 2019 and a history of tuberculosis treatment. Patients with drug-resistant tuberculosis were excluded. Results. A total of 605 patients with a treatment history were included, 60% due to unfinished treatment and 40% due to relapse. Compared to patients reentering due to relapse (ORa=2.34, CI=1.62-3.38), the independent variables associated with treatment failure at discharge were homelessness (ORa=2.45, CI=1.54-3.89), substance dependence (ORa=1.95, CI=1.24-3.05), tuberculosis/HIV coinfection (ORa=1.69, CI=1.00-2.86), diabetes (ORa=1.89, CI=1.29-2.77), and unfinished previous tuberculosis treatment due to follow-up loss, abandonment, or other causes. Programmatic variables favoring treatment success were voluntary HIV testing counseling (p<0.001) and HIV testing (p<0.001). Conclusion. Homelessness, substance dependence, tuberculosis/HIV coinfection, diabetes, and incomplete previous treatment due to loss to follow-up, abandonment, or treatment failure hindered the success of antituberculosis. These characteristics should be identified and addressed during the initial care of patients reentering treatment for tuberculosis.

Tromboembolia pulmonar masiva en un paciente con enfermedad de Crohn y tuberculosis latente tratada con ustekinumab

La enfermedad inflamatoria intestinal (EII) es un espectro de enfermedades crónicas inmunomediadas que afectan tanto el tracto gastrointestinal, como otros sistemas extraintestinales, comportándose como una enfermedad sistémica. Los fenómenos tromboembólicos son una complicación frecuente en la EII, como consecuencia de los estados de hipercoagulabilidad que se asocian con la actividad de la enfermedad, y su aparición tiene un impacto negativo tanto en el pronóstico como en la sobrevida de los pacientes. Debido a ello, el control de la actividad inflamatoria de la EII es uno de los pilares en el control de los eventos tromboembólicos. Los medicamentos biológicos se asocian al control rápido del cuadro inflamatorio, sin embargo, siempre se discute el tema de seguridad para la reactivación de infecciones latentes, en particular tuberculosis. Presentamos el caso de un paciente de 37 años que debutó con trombosis venosa profunda en el miembro inferior izquierdo y posteriormente con tromboembolismo pulmonar masivo. Luego de investigar la etiología y ampliar la historia clínica se le diagnosticó Enfermedad de Crohn (EC). Al realizar los estudios previos al uso de biológicos, las pruebas de PPD y quantiferon resultaron positivas, luego de la discusión del caso se decidió iniciar tratamiento con ustekinumab.

Inflammatory bowel disease (IBD) is a spectrum of chronic immune-mediated diseases that affect the gastrointestinal tract and other extraintestinal systems, behaving as a systemic disease. Thromboembolic phenomena are a frequent complication in IBD, because of hypercoagulability states associated with disease activity, and their presence has a negative impact on prognosis and patient survival. Due to this, the control of the inflammatory activity of IBD is one of the pillars in the control of thromboembolic events. Biological drugs are associated with rapid control of the inflammatory process, however, the security profile for the reactivation of latent infections, particularly tuberculosis, is always discussed. We present the case of a 37-year-old patient who presented with deep vein thrombosis in the left lower limb and later with massive pulmonary thromboembolism. During his evaluation, he was diagnosed with Crohn's disease (CD). When carrying out the studies prior to the use of biologics, PPD and quantiferon tests were positive. After discussing the case, we decided to start treatment with ustekinumab.

Asociación entre preocupación frente a la COVID-19, el apoyo social y el conocimiento sobre tuberculosis con el cumplimiento del tratamiento antituberculoso en Lima, Perú / Association between concern about COVID-19, social support and knowledge about tuberculosis with adherence to antituberculosis treatment in Lima, Perú

Introducción. En el contexto de la pandemia por la COVID-19 es escasa la información de factores asociados al cumplimiento del tratamiento antituberculoso en las zonas de alta prevalencia de tuberculosis. Objetivo. Evaluar si existe asociación entre el apoyo social, la preocupación por el contagio de COVID-19 y el conocimiento de la tuberculosis, frente al incumplimiento del tratamiento antituberculoso. Materiales y métodos. Se trata de un estudio transversal de pacientes en tratamiento antituberculoso durante los meses de enero a marzo del 2022 en centros ubicados en áreas de alta prevalencia de tuberculosis en Lima. Se utilizó el cuestionario de Morisky Green-Levine para evaluar el cumplimiento del tratamiento como variable dependiente; las variables independientes se evaluaron usando el Medical Outcomes Study Social Support Survey para determinar el apoyo social percibido y la preocupación por la infección de COVID-19, y el test de Batalla para evaluar el conocimiento del paciente sobre su enfermedad. Se utilizó la regresión de Poisson con varianza robusta para determinar la asociación entre las variables. Resultados. De un total de 101 participantes (73,3 % hombres y edad media 35,1 ± 16 años), el 51,5 % no observaron el tratamiento antituberculoso. El nivel de preocupación medio o alto de contagiarse y desarrollar COVID-19 se asoció con una mayor prevalencia de incumplimiento del tratamiento (razón de prevalencia: 1,68; intervalo de confianza del 95 %: 1,09-2,57) (ajustada por las variables de confusión consideradas). Conclusiones. El incumplimiento del tratamiento antituberculoso es una condición frecuente entre los pacientes de una zona de alta prevalencia de tuberculosis en Lima especialmente entre aquellos con mayor preocupación al contagio por el virus de SARS- CoV-2, causante de la COVID-19.

Introduction. In the context of the COVID-19 pandemic, information on factors associated with adherence to antituberculosis treatment in areas with high prevalence of tuberculosis is scarce. Objective. To evaluate whether there is an association between social support, concern about COVID-19 infection and knowledge about tuberculosis, and non-adherence to antituberculosis treatment. Materials and methods. A cross-sectional study was carried out on patients under antituberculosis treatment, from January to March, 2022, in centers located in areas with a high prevalence of tuberculosis in Lima. We used the Morisky Green-Levine questionnaire to assess adherence to treatment as the dependent variable; the independent variables were evaluated using the Medical Outcomes Study Social Support Survey for perceived social support and concern about COVID-19 infection, and the Battle Test to assess patients' knowledge about their disease. We used Poisson regression with robust variance to evaluate the association between the independent variables and the dependent one. Results. Out of 101 participants (73.3% male with an average age of 35.1 ±16 years), 51.5% were non-adherent to antituberculosis treatment. Medium or high level of concern about getting COVID-19 was associated with a higher prevalence of non-adherence to treatment (odds ratio: 1.68; 95 % confidence interval: 1.09-2.57) (adjusted for considered confounding variables). Conclusions. Non-adherence is a frequent condition among patients living in an area with a high prevalence of tuberculosis in Lima, especially among those with a higher concern for COVID-19 infection.

Analysis of the role of molecular diagnostic technology in improving the bacteriological diagnostic rate of tuberculosis / 中华传染病杂志

Objective:To analyze the relevant factors of bacteriological diagnosis rate in pulmonary tuberculosis in Zhejiang Province, and to provide basis for the control of tuberculosis.Methods:The results of etiology detection of pulmonary tuberculosis in Zhejiang Province from 2015 to 2020 were collected from the China Tuberculosis Information Management System. Positive detection of etiology of pulmonary tuberculosis cases was analyzed. Joinpoint regression model was constructed to evaluate the annual trend of the positive rate of etiology, and linear regression model was used to analyze the influence of new diagnostic technology on the positive detection rate of etiology in smear-negative pulmonary tuberculosis cases.Results:From 2015 to 2020, the positive rate of etiology of pulmonary tuberculosis in Zhejiang Province increased from 38.66%(10 588/27 385) to 64.12%(14 275/22 262), with an average annual growth rate of 8.80%. All of the 11 prefecture cities in Zhejiang Province showed an increasing trend of the positive rate of etiology. The average annual growth rates in Wenzhou City and Lishui City were 10.27% and 11.21%, respectively, and the positive rates of etiology in Jinhua City and Lishui City were 70.13%(2 007/2 862) and 73.34%(707/964) in 2020, respectively. From 2015 to 2020, smear-negative cases accounted for 61.66%(92 935/150 733) in Zhejiang Province, and the further detection rate by culture and molecular test increased from 0.13%(22/16 650) to 84.74%(11 384/13 434). The positive rate of bacteriological tests in smear-negative pulmonary tuberculosis patients increased from 0.04%(6/16 650) to 41.28%(5 546/13 434). If the culture and molecular detection rate increased to 100.00%, the linear regression model predicted positive rate of etiology could increase to 44.20%. Thus, the positive rate of etiology of pulmonary tuberculosis in Zhejiang Province would reach 66.00%. Up to 2020, 95.56%(86/90) and 92.22%(83/90) of tuberculosis designated hospitals were equipped with molecular and liquid diagnostic equipments, respectively, and the detection positive rates of molecular and liquid diagnostics in the etiology positive pulmonary tuberculosis cases were 71.24%(10 169/14 275) and 53.44%(7 629/14 275), respectively.Conclusions:The implementation and promotion of the new diagnostic techniques for tuberculosis, especially the molecular diagnostic techniques, could significantly improve the positive rate of etiology of pulmonary tuberculosis etiology. Methods and strategies of etiological diagnosis of tuberculosis should be paid more attention in prevention and control of tuberculosis.

Risk factors of drug resistance in diabetes mellitus complicated by pulmonary tuberculosis / 中国基层医药

Objective:To investigate the risk factors of diabetes mellitus complicated by pulmonary tuberculosis.Methods:The clinical data of 83 patients with diabetes mellitus complicated by pulmonary tuberculosis who received treatment in Taiyuan Fourth People's Hospital from March 2020 to March 2022 were collected. These patients were divided into sensitive group ( n = 45) and resistant group ( n = 38 ) according to the results of drug sensitivity test. Univariate and multivariate non-conditional logistic regression was performed to analyze the influential factors of drug resistance. Results:Univariate logistic regression results revealed that there were significant differences in blood CD4 +T lymphocyte count ( χ2 = 11.73, P = 0.001) and diabetic complications ( χ2 = 4.94, P = 0.026). Multivariate non-conditional logistic regression analysis was performed taking whether blood CD4 +T lymphocyte count was lower than the average level and whether patients with diabetes mellitus had complications as independent variables, and taking whether drug resistance was a dependent variable. The results showed that the OR (95% CI) value of the decreased blood CD4 +T lymphocyte count was 4.909 (1.926-12.514). It is a risk factor for drug resistance of diabetes mellitus complicated by pulmonary tuberculosis. Conclusion:The decrease of blood CD4 +T lymphocyte count is a risk factor of drug resistance in diabetes mellitus complicated by pulmonary tuberculosis, and it should be intervened early in the clinic.

Clinical characteristics among patients with pulmonary tuberculosis complicated by prediabetes mellitus / 中国基层医药

Objective:To analyze the clinical characteristics of pulmonary tuberculosis (PTB) in patients with prediabetes mellitus (PreDM) and improve the understanding and diagnosis of pulmonary tuberculosis complicated by prediabetes mellitus (PreDM-PTB).Methods:The clinical data of 109 inpatients with PTB who underwent glycated hemoglobin A1c (HbA1c) examination admitted to Beijing Chest Hospital, Capital Medical University from January 2015 to January 2016 were retrospectively analyzed. These patients were divided into the PreDM-PTB group ( n = 45) and the non-PreDM-PTB group (N-PreDMPTB group, n = 64) according to HbA1c test results. Patient demographic data, clinical features, imaging data, bacteriological results, and other laboratory results were collected from all patients. Results:The mean age and body mass index (BMI) were higher in the PreDM-PTB group than the N-PreDMPTB group. The proportion of patients having a smoking history was higher in the PreDM-PTB group than the N-PreDMPTB group (46.7% vs. 25.0%). The proportions of patients who had a cough (88.9%), fever (55.6%), anorexia (17.8%), chest tightness (31.1%), shortness of breath (28.9%), weight loss (40.0%), and pleural effusion (22.2%) were higher in the PreDM-PTB group than the N-PreDMPTB group. Patients with PreDM-PTB were more prone to develop anemia (55.6%), hypoproteinemia (55.6%), and increased low-density lipoprotein (26.7%) compared with patients with N-PreDMPTB. The levels of D-Dimer (93.2%), C-reactive protein (86.7%), and erythrocyte sedimentation rate (79.1%) were increased in the PreDM-PTB group compared with the N-PreDMPTB group. Sputum smear results showed that the positivity of mycobacterium tuberculosis was higher in the PreDM-PTB group (74.4%) compared with the N-PreDMPTB group. There was no significant difference in drug resistance between the two groups ( P > 0.05). The positivity of blood tuberculosis antibody and blood T-cell spot test for tuberculosis infection were 60.9% and 84.6% respectively in the PreDM-PTB group and they were 50.9% and 95.2% respectively in the N-PreDMPTB group. There were no significant differences in these two indices between the two groups ( P = 0.321, 0.066). Conclusion:Patients with Pre-DMPTB have different clinical manifestations and auxiliary examination characteristics compared with patients with N-PreDMPTB patients, which should be paid more attention to by clinicians. Early intervention should be actively adopted to prevent diabetes development from pre-DM.

Objective:To investigate the effect of early interventional therapy with fiberoptic bronchoscope in patients with inflammatory infiltrating type (Ⅰ type) tracheobronchial tuberculosis (TBTB).Methods:Using prospective research methods, 306 patients with Ⅰ type TBTB diagnosed by fiberoptic bronchoscopy in the Third People′s Hospital of Kunming City from January 2019 to April 2022 were selected. The patients were divided into observation group and control group according to the random number table method with 153 cases each. The patients in control group were given routine anti-tuberculosis chemotherapy, and the patients in observation group were given routine anti-tuberculosis chemotherapy combined with early interventional therapy with fiberoptic bronchoscope. Sputum smear examination and tuberculosis culture were performed at the end of 1, 3 and 6 months of treatment, and the negative conversion of sputum culture was recorded. Chest X-ray, pulmonary function and fiberoptic bronchoscope were performed at the end of 1, 3 and 6 months of treatment to evaluate the improvement rate of clinical symptoms, effective absorption rate of lesions and effective absorption rate of obstructive pneumonia. The CD 4+, CD 8+, CD 4+/CD 8+, interferon γ (IFN-γ), interleukin-6 (IL-6) and C reactive protein (CRP) before and after treatment were detected. The random walking model of immune inflammation was evaluated. Results:The sputum negative conversion rates at the end of 1, 3 and 6 months of treatment in observation group were significantly higher than those in control group: 64.71%(99/153) vs. 52.29%(80/153), 80.39%(123/153) vs. 62.09%(95/153) and 91.50%(140/153) vs. 73.86%(113/153), and there were statistical differences ( P<0.05 or <0.01). The improvement rate of clinical symptoms at the end of 1 month of treatment in observation group was significantly higher than that in control group: 94.77%(145/153) vs. 66.67%(102/153), and there was statistical difference ( P<0.01); the clinical symptoms disappeared in both groups at the end of 3 and 6 months of treatment. The effective absorption rates of lesions at the end of 1 and 3 months of treatment in observation group were significantly higher than those in control group: 73.20%(112/153) vs. 51.63%(79/153) and 96.73%(148/153) vs. 85.62%(131/153), and there were statistical differences ( P<0.01); all the lesions were absorbed at the end of 6 months of treatment in both groups. The effective absorption rates of obstructive pneumonia at the end of 1 and 3 months of treatment in observation group were significantly higher than those in control group: 78.43% (120/153) vs. 39.87%(61/153) and 89.54%(137/153) vs. 79.08%(121/153), and there were statistical differences ( P<0.01 or <0.05); all obstructive pneumonia were absorbed at the end of 6 months of treatment in both groups. There were no statistical differences in CD 4+, CD 8+, CD 4+/CD 8+, IL-6, IFN-γ and CRP before treatment between the two groups ( P>0.05); the CD 4+, CD 4+/CD 8+ and IFN-γ after treatment in observation group were significantly higher than those in control group: 0.343 ± 0.032 vs. 0.311 ± 0.023, 1.37 ± 0.18 vs. 1.12 ± 0.16 and (38.47 ± 3.50) ng/L vs. (20.52 ± 2.96) ng/L, the CD 8+, IL-6 and CRP were significantly lower than those in control group: 0.251 ± 0.020 vs. 0.268 ± 0.021, (19.40 ± 3.31) ng/L vs. (34.58 ± 5.82) ng/L and (10.41 ± 2.87) mg/L vs. (17.47 ± 3.14) mg/L, and there were statistical differences ( P<0.01). The evaluation results of random walking model showed that CD 4+, CD 8+, CD 4+/CD 8+, IFN-γ, IL-6 and CRP in the observation group were better than those in the control group in the maximum random fluctuation, number of walking steps, positive walking growth rate, random fluctuation power law value, comprehensive improvement rate, recording times of comprehensive evaluation index and expected improvement value. Conclusions:Early interventional therapy with fiberoptic bronchoscope can effectively assist systemic drug therapy in patients with Ⅰ type TBTB, which can accelerate focus absorption, promote sputum negative conversion, enhance cellular immunity and effectively inhibit inflammatory reaction.

Spatial temporal feature of tuberculosis among high school students in Gansu Province from 2018 to 2022 / 中国学校卫生

Objective@#To analyze the spatial temporal distribution characteristics of tuberculosis among high school students at county levels in Gansu Province from 2018 to 2022,so as to provide a scientific basis for tuberculosis prevention and control in schools.@*Methods@#Tuberculosis data from high school students in counties (districts) reported in Gansu Province from 2018 to 2022 was collected from the Tuberculosis Information Management System and Infectious Disease Information Reporting System of the Chinese Disease Prevention and Control Information Management System. Demographic data of high school students in counties (districts) came from the General Management System of the Chinese Disease Prevention and Control Information Management System, and the spatial clustering of the reported incidence rate of pulmonary tuberculosis among high school students in Gansu Province in the past five years was analyzed using the methods of global spatial autocorrelation (Moran s I) and local indicators of spatial audocorrelation(LISA).@*Results@#A total of 41 885 pulmonary tuberculosis cases were reported in various counties of Gansu Province From 2018 to 2022, with an average reported incidence rate of 32.81/100 000. During the same period, 1 170 high school students cases were reported, with an average reported incidence rate of 13.72/100 000. With the exception of 2020, the reported incidence rate of pulmonary tuberculosis among high school students was non random distribution in other 4 years, showed a moderate intensity of spatial clustering. From 2018 to 2022, most counties in Gansu Province reported that the incidence rate of pulmonary tuberculosis among high school students was 10.00/100 000 or below, the counties with reported incidence rate >40.00/100 000 were mainly distributed in Luqu County, Maqu County, Diebu County, Hezuo City, Xiahe County of Gannan Prefecture, Gangu County and Wushan County of Tianshui Prefecture, Wenxian County and Kangxian County of Longnan Prefecture, Huachi County of Pingliang Prefecture, Huanxian County of Qingyang Prefecture. The number of counties where the reported incidence rate of tuberculosis among high school students more than 30.00/100 000 gradually decreased from 2018 to 2022. In the past five years, the reported incidence rate of tuberculosis among high school students in all counties of Gannan Prefecture remained above 40.00/ 100 000 . The LISA analysis results showed that the high incidence areas were mainly concentrated in Gannan Prefecture.@*Conclusions@#The epidemic situation of pulmonary tuberculosis among high school students in Gansu province from 2018 to 2022 is still a serious condition, showing the characteristics of unbalanced regional distribution. The reported incidence rate shows a strong spatial clustering, and the hot spots are concentrated in the counties (districts) of Gannan prefecture in Gansu Province.

Delay on detection, and diagnosis of pulmonary tuberculosis and the influencing factors in Inner Mongolia students during 2011-2022 / 中国学校卫生

Objective@#To analyze the delay on detection, care seeking, diagnosis and treatment of tuberculosis among students in Inner Mongolia Autonomous Region (Inner Mongolia) from 2011 to 2022 and its influencing factors, so as to provide support for the prevention and treatment of tuberculosis among students.@*Methods@#The general demographic indicators of students with tuberculosis in Inner Mongolia from January 1, 2011 to December 31, 2022 were collected from the infectious disease monitoring (new) module of the China Disease Prevention and Control Information System. General characteristics and trend of four types of delayed pulmonary tuberculosis patients in students were analyzed. The influencing factors were analyzed using univariate and multivariate Logistic regressions.@*Results@#From 2011 to 2022, there were 6 032 cases of pulmonary tuberculosis among students in Inner Mongolia. The rates of delayed detection, delayed care seeking, delayed diagnosis, and delayed treatment were 51.71%, 64.01%, 7.82 %, and 2.30%, respectively. The results of multivariate Logistic regression analysis showed that tracking ( OR =1.51) in the patient source,league level diagnosis ( OR =3.16) in the diagnostic institution level,and county level diagnosis ( OR =2.41) were positively associated with delayed discovery ( P <0.05). At the level of diagnostic unit, league city level diagnosis ( OR =2.69), and county level diagnosis ( OR =3.67) associated with more delayed care seeking ( P <0.05). Referral ( OR =1.58) and follow up ( OR =2.55), floating population ( OR =2.05), further consultation with a doctor ( OR =2.11), and no results in imaging manifestations ( OR =2.19) were positively associated with delayed diagnosis( P <0.05). The factors contributing to delayed treatment were referral ( OR =1.84), follow up ( OR =4.91), active screening ( OR =5.46), and floating population( OR =1.95)( P <0.05).@*Conclusions@#From 2011 to 2022, the delay on detection and care seeking for tuberculosis patients among students in Inner Mongolia is at a relatively high level, while the delay in diagnosis and treatment is at a relatively low level but shows an increasing trend. It is necessary to focus on the factors associated with delays in identification, diagnosis and treatment in tuberculosis outbreak in the context of school to prevent or reduce school tuberculosis outbreak.

A 5-year follow up analysis of cases in a high school tuberculosis outbreak / 中国学校卫生

Objective@#To explore the effectiveness of preventive treatment for latent tuberculosis infection (LTBI) patients, so as to provide reference for the management and preventive treatment of clustered epidemic in schools.@*Methods@#Data came from the school tuberculosis outbreak of a boarding high school in Kaizhou District, Chongqing, which occurred between June 2017 and March 2018 among 2016 grade high school teachers and students for investigation and analysis. The total incidence, LTBI patients, and the incidence after preventive treatment for 5 years were followed up.@*Results@#A total of 34 cases of pulmonary tuberculosis from June 2017 to March 2018. A total of 1 357 individuals were screened for 6 concentrated contact screenings, with a confirmed tuberculosis rate of 2.43%, a tuberculosis skin test (TST) positive rate of 27.41%, and a strong TST positive rate of 7.39%. Among them, the confirmed tuberculosis rate and TST positive rate in the first case class were much higher than those in other classes, with statistically significant differences ( χ 2=286.30, 98.59, P ＜0.01). 88 cases of LTBI were found, with 31 cases receiving preventive treatment (35.23%), of which 28 completed preventive treatment (90.32%). After five years of follow-up, 73 cases of pulmonary tuberculosis were diagnosed in 2016 by the school senior high school, with a incidence rate of 0.98/10 2 (person/person years). Fifteen of the 88 LTBI patients were diagnosed with pulmonary tuberculosis, and the incidence rate was 3.33/10 2 (person/person years). The incidence rate of the preventive treatment group was 0.7/10 2 (person/person years)lower than that of the medical observation group 4.5/10 2 (person/person years), with a statistically significant difference ( χ 2=4.31, P ＜0.05).@*Conclusion@#The classes with higher TST positive rate and strong positive rate have higher incidence rate. Improving the preventive treatment rate of LTBI patients can effectively reduce the incidence rate of tuberculosis.

Efficacy and safety evaluation of the regimen containing Bedaquiline in elderly patients with drug-resistant pulmonary tuberculosis / 中华老年医学杂志

Objective:To evaluate the efficacy and adverse reactions of the regimen containing Bedaquiline in elderly patients with multi-drug resistant tuberculosis.Methods:From March 2019 to June 2022, patients with multi-drug resistant pulmonary tuberculosis admitted to Anhui Chest Hospital were randomly divided into two groups: the observation group was given a treatment containing Bedaquiline, and the control group was given a treatment without Bedaquiline.Patients were also divided into elderly patients(age ≥60 years old)and non-elderly patients(age <60 years old)according to age.Sputum culture conversion, lesion absorption and adverse reactions were compared between the observation group and the control group in general, elderly and non-elderly patients, respectively.Results:A total of 170 cases were collected, including 79 in the observation group and 91 in the control group.Sputum culture conversion: The sputum culture conversion rates of observation groups in general, non-elderly and elderly patients were better than that of control groups at the 3rd month after treatment(the general, 96.2% vs.75.8%, χ2=14.001, P<0.001; the non-elderly, 94.9% vs.82.1%, χ2=4.675, P=0.031; the elderly, 100.0% vs. 65.7%, χ2=8.771, P=0.003), and at the 6th month, the rates of overall observation group was better than that of control group(98.7% vs.92.3%, χ2=3.895, P=0.048); the rates of non-elderly and elderly observation group and control group were all greater than 90%, with no statistical significance( P>0.05). Lesion absorption: Overall and non-elderly observation groups were better than control group in lesion absorption at the 3rd month(the general, 84.8% vs.68.1%, χ2=12.962, P=0.002; the non-elderly, 88.1% vs.71.4%, χ2=9.832, P=0.007; and the 6th month(the general, 88.6% vs.76.9%, χ2=14.888, P=0.001; the non-elderly, 89.8% vs.82.1%, χ2=8.618, P=0.013). The focal absorptivity of senile observation group at the end of March and June were 75.0% and 85.0%, respectively, both better than control group, but the difference was not statistically significant( P>0.05). Adverse reactions: Overall and non-senile observation groups had longer QT interval than control groups( P<0.05), but no patients stopped bedaquiline because of this, and there was no significant difference in QT interval between the two groups( P>0.05). Conclusions:In elderly patients with multi-drug resistant pulmonary tuberculosis, early sputum culture conversion turns fast after treatment with Bedaquiline, which has good therapeutic effect, good tolerance and controllable adverse reactions.

Status quo and influencing factors of medication compliance in young newly diagnosed pulmonary tuberculosis patients / 中国实用护理杂志

Objective:To investigate the medication adherence and its influencing factors in young newly diagnosed pulmonary tuberculosis patients during different treatment periods, in order to provide a theoretical basis for formulating precise medication management strategies and thus improving the treatment success rate.Methods:A cross-sectional survey was conducted using a stratified random sampling method to select 283 young newly diagnosed pulmonary tuberculosis patients who visited and registered in the Kashgar region of Xinjiang from September 2021 to February 2022. The patients were divided into three groups according to the treatment time of receiving standard chemotherapy regimen: A (1-2 months of medication), B (3-4 months of medication), and C (5-6 months of medication), with 77, 89, and 117 cases, respectively. The clinical data of tuberculosis patients were collected by using the general information questionnaire,Eight-Item Morisky Medication Adherence Scale and Tuberculosis Medication Adherence Scale for tuberculosis patients.Results:Those who take medication well of three groups of young newly treated pulmonary tuberculosis patients were 93.5% (72/77), 89.9% (80/89), and 82.1% (96/117), respectively. The difference among the three groups was statistically significant ( χ2=6.23, P<0.05). Logistic regression analysis showed that social support was an influential factor for the 1st to 2nd month of medication ( OR=0.536, P<0.05); treatment confidence and psychological status were influential factors for the 3rd to 4th month of medication ( OR=0.668, 2.212, both P<0.05); comorbidity, social support, psychological status, and coping style were influential factors for the 5th to 6th month of medication ( OR values were 0.428 - 9.518, all P<0.05). Conclusions:The relevant factors that affect medication adherence vary among young newly diagnosed pulmonary tuberculosis patients at different stages of treatment. Accurate medication management strategies should be developed based on the influencing factors at each stage.

Masa pulmonar como manifestación primaria de tuberculosis en pediatría: reporte de un caso / Pulmonary tuberculosis presenting as a lung mass in children: case report

La tuberculosis es una de las principales causas infecciosas de muerte en el mundo y es endémica en Argentina. La mayoría de los casos de tuberculosis son de localización pulmonar; el tuberculoma una complicación infrecuente. Se describe un caso clínico de presentación pulmonar atípica de tuberculosis. Se trata de una niña de 15 meses, previamente sana, derivada a neumología por fiebre, mal progreso de peso e imagen persistente por 2 meses en la radiografía de tórax a pesar de haber recibido antibioticoterapia. Antecedente de contacto estrecho con persona sintomática respiratoria. Se internó para estudio, mostró una PPD de 13 mm y una masa voluminosa heterogénea en el lóbulo superior izquierdo en la tomografía computada de tórax. Se realizaron tres lavados gástricos y toracoscopia exploratoria con biopsia pulmonar con rescate de Mycobacterium tuberculosis en cultivos. Se diagnosticó tuberculoma pulmonar y realizó tratamiento estándar con fármacos antituberculosos con evolución favorable.

Tuberculosis is one of the main causes of death due to infection around the world. Although tuberculosis frequently involves lung parenchyma, tuberculoma is a rare complication. We describe an atypical pulmonary presentation of tuberculosis. A 15-month-old girl, previously healthy, was referred to the pulmonology department due to fever, poor weight gain, and a 2-months persistent lung image on chest x-ray despite antibiotic therapy. She had been in frequent contact with a respiratory symptomatic subject. She was admitted to the hospital with a TST of 13 mm and a heterogeneous bulky mass in the left upper lobe at chest computed tomography. Three gastric lavages were done and the patient underwent exploratory thoracoscopy and lung biopsy, with positive cultures for Mycobacterium tuberculosis. The diagnosis of pulmonary tuberculoma was confirmed, and the patient received standard anti- tuberculosis therapy with a favorable evolution.

Factores que afectan la cobertura del programa de tuberculosis en el primer nivel de atención en Honduras / Factors affecting the tuberculosis program coverage at the first level of care in Honduras

Introducción. Hay consenso global en que el diagnóstico y el tratamiento precoces de la tuberculosis pueden acelerar su control y mitigar sus consecuencias. En Honduras, la tasa de mortalidad por la enfermedad aumentó gradualmente entre 2014 y 2018, a lo que se suman las reformas en el sistema de salud del 2014 y la implementación parcial de la estrategia "Fin a la TB". Objetivo. Analizar las barreras y los elementos facilitadores del diagnóstico y el tratamiento que afectan la cobertura del programa nacional de tuberculosis, con el fin de brindar herramientas para la implementación efectiva de la estrategia "Fin a la TB" en San Pedro Sula, Honduras, 2015-2019. Materiales y métodos. Se hizo un estudio mixto secuencial y explicativo de pacientes mayores de 18 años con tuberculosis pulmonar positivos en la baciloscopia. Se revisaron las fichas de notificación de la enfermedad y las historias clínicas en dos establecimientos de salud de primer nivel y se hicieron entrevistas semiestructuradas al personal de salud, los pacientes y los familiares. Resultados. En el 74,6 % (297/398) de los casos no hubo diagnóstico oportuno. En este grupo, se encontró una mayor proporción de hombres (62,3 %; 185/297) y de adultos (80,8 %; 240/297); predominó un nivel de escolaridad inferior a la secundaria (53,7 %; 108/297); el 49,2 % (123/297) de los pacientes tenía alguna ocupación, y el 98,2 % había recibido tratamiento oportuno. Se detectaron las siguientes barreras: condiciones socioeconómicas precarias, desarticulación del sistema de salud público y privado, y límites fronterizos entre maras y pandillas. Los elementos facilitadores fueron la buena atención y la actitud del personal de salud, y la disponibilidad y reserva de tratamiento. Conclusiones. La falta de oportunidad en el diagnóstico de tuberculosis afectó la cobertura del programa nacional como resultado de las barreras culturales y de atención en salud.

Introduction: There is a global consensus that early diagnosis and treatment of tuberculosis (TB) can accelerate its control and mitigate its consequences. The gradual increase in the TB mortality rate from 2014 to 2018 in Honduras, the reform of the health system in 2014, and the partial implementation of the "End TB" strategy motivated this study. Objective: To analyze barriers to and facilitators of diagnosis and treatment affecting the national TB program coverage using data from 2015 to 2019 and provide tools for the effective implementation of the "End TB" strategy in San Pedro Sula, Honduras. Materials and methods: This was an explanatory sequential mixed-methods study on smear-positive pulmonary TB patients older than 18 years of age. TB notification sheets and medical records from two primary health care facilities were reviewed. Semistructured interviews were conducted with health care providers, patients, and their families. Results: A total of 74.6% of the cases (297/398) did not receive a timely diagnosis; 62.3% (185/297) were men, 80.8% (240/297) were adults, 53.7% (108/297) had less than high school education, 49.2% (123/297) had some occupation, and 98.2% of participants received timely treatment. Identified barriers included low socioeconomic conditions, lack of coordination between public and private health systems, and boundaries set by gangs. Identified facilitators included good care and attitude of the health care personnel and the availability of medications. Conclusions: The lack of opportunity to diagnose the disease affected the coverage of the national TB program due to cultural and health care barriers.

Tuberculosis pulmonar en paciente con signo de la raqueta de tenis. Presentación de un caso

RESUMEN La tuberculosis pulmonar puede afectar cualquier órgano y sus manifestaciones clínicas son variables. Se presenta un caso de tuberculosis pulmonar con diagnóstico, tratamiento y seguimiento en la Atención Primaria de Salud. La paciente de 52 años de edad, dispensarizada como adulto grupo III, riesgo de tuberculosis pulmonar, hipertensa y diabética, fue atendida en su consultorio médico de la familia por presentar malestar general, tos productiva y persistente mayormente en horario de la noche, anorexia y astenia. Había convivido durante cinco años con dos familiares diagnosticados de tuberculosis pulmonar. El examen radiológico y el estudio microbiológico confirmaron el diagnóstico. El tratamiento logró la mejoría, evidente desde el punto clínico y radiológico; así como la disminución de la codificación en la baciloscopia. La confirmación del diagnóstico resulta fundamental, sobre todo en aquellos pacientes con factores de riesgo. La radiografía de tórax y la baciloscopia garantizan el seguimiento. La imagen radiográfica cavitaria extendida, también conocida como signo de la raqueta de tenis o punta de flecha, se observa con poca frecuencia en el diagnóstico en la comunidad.

ABSTRACT Pulmonary tuberculosis can affect any organ and its clinical manifestations are variable. A case of pulmonary tuberculosis with diagnosis, treatment and follow-up in Primary Health Care is presented. The 52-years-old patient, discharged as a group III adult, at risk of pulmonary tuberculosis, hypertensive and diabetic, was treated at her family doctor's office due to physical discomfort, productive and persistent cough mainly at night, anorexia and asthenia. She had lived for five years with two relatives diagnosed with pulmonary tuberculosis. Radiological examination and microbiological study confirmed the diagnosis. The treatment achieved the improvement, evident from the clinical and radiological point of view; as well as the decrease in the coding in the bacilloscopy. Confirmation of the diagnosis is essential, especially in those patients with risk factors. Chest X-ray and smear microscopy guarantee follow-up. The extended cavitary radiographic image, also known as the tennis racket or arrowhead sign, is rarely seen at diagnosis in the community.

Caracterización clínica y microbiológica de pacientes con trazas en Xpert MTB/RIF Ultra / Clinical and microbiological characterization of patients with Xpert MTB/RIF Ultra traces

INTRODUCCIÓN: El Xpert MTB/RIF Ultra (Ultra) ha mejorado dramáticamente el diagnóstico de la tuberculosis (TBC). Con él ha nacido la categoría de trazas, que es la menor carga bacilar detectable por este examen. OBJETIVO: Describir las características clínicas de los pacientes con presencia de trazas en el Ultra y evaluar la confirmación de la TBC como diagnóstico clínico. MATERIALES Y MÉTODOS: Estudio descriptivo de serie de casos. Se extrajo la información de fichas clínicas de pacientes con positividad a trazas. Se confrontaron datos clínicos, microbiológicos e histopatológicos. RESULTADOS: Se analizaron 21 pacientes. La edad promedio fue de 52 años. Todos los casos presentaron baciloscopias negativas. Cuatro cultivos en medio líquido MGIT fueron positivos, dos en pleura parietal, uno en líquido pleural y otro en expectoración. En pleura parietal, tres casos presentaron granulomas con necrosis caseosa y un granuloma esbozos de necrosis. En tejido pulmonar se observaron dos casos con granulomas con esbozos de necrosis y dos con granulomas no necrotizantes. Tres pacientes tenían el antecedente de TBC previa, se interpretó la positividad de trazas en ellos como falsos positivos. Finalmente se diagnosticaron 13 casos como TBC activa, donde cinco de ellos fueron TBC pleurales. La mayor concordancia clínica, microbiológica e histopatológica fue en muestras de líquido y tejido pleural. DISCUSIÓN: Se debe interpretar con cautela los hallazgos de esta prueba en muestras de vía aérea; el análisis multidisciplinario (clínica, imágenes, microbiología, histología) es crucial en las decisiones de nuestras conductas clínicas futuras. El hallazgo de trazas en pleura tiene, a nuestro parecer, un alto valor diagnóstico en el estudio de la tuberculosis en esta localización.

INTRODUCTION: Xpert MTB/RIF Ultra has dramatically changed the diagnosis of tuberculosis. A new category called traces appeared, which is the smallest amount of bacillar load detectable. OBJECTIVE: Describe the clinical characteristics of patients that present traces in Xpert MTB/RIF Ultra test, and to evaluate the confirmation of tuberculosis as clinical diagnosis. METHODS: We perform a descriptive case series study. Information was recovered from clinical records of patients with positive test for traces. Clinical, histopathological and microbiological results were confronted. RESULTS: Twenty one patients were analyzed. The mean age was 52 years-old. All cases had negative smear microscopy and four MGIT cultures were positive, two in pleural fluid and another in sputum. In parietal pleura, three cases presented granulomas with caseous necrosis, and one showed granuloma with very little necrosis. In pleural tissue we observed two cases of granulomas with traces of necrosis and two with non-necrotizing granulomas. Three patients had history of previous tuberculosis and positive traces, the test was interpreted as a false positive result. Finally, active tuberculosis was diagnosed in 13 cases, and five of them were pleural tuberculosis. The highest clinical, microbiological and histopathological agreement was in fluid and pleural tissue samples. DISCUSSION: The findings of Xpert MTB/RIF Ultra in airway samples must be interpreted carefully. Multi-disciplinary analysis is crucial in future clinical decisions. The finding of traces in pleura has, in our opinion, a high diagnostic value in the study of tuberculosis in this location.

Tuberculose pulmonar causada pelo uso de infliximab em paciente com Doença de Crohn / Pulmonary tuberculosis caused by the use of infliximab in a patient with Crohn's Disease

A doença de Crohn é uma patologia caracterizada pela inflamação transmural do trato gastrointestinal, compondo o espectro das doenças inflamatórias intestinais. Nos casos mais graves, dispõe de tratamento com uso de agentes biológicos e imunomoduladores que podem à reativação ou exacerbação de doenças infecciosas preexistentes. Este relato de caso trata de uma paciente do sexo feminino de 24 anos, diagnosticada com Doença de Crohn há 10 anos, evoluindo com necessidade de tratamento com infliximab e, após período de menos de 1 ano, apresentou odinofagia progressiva, dor abdominal e diarreia, além de perda ponderal, sudorese noturna e febre diária. Tomografia computadorizada de tórax evidenciou árvore em brotamento, sendo confirmado diagnóstico de tuberculose pulmonar pelo Teste Rápido Molecular no escarro e provável tuberculose laríngea e intestinal.

Crohn's disease is a pathology characterized by transmural inflammation of the gastrointestinal tract, comprising the spectrum of Inflammatory Bowel Diseases. In the most severe cases, treatment using biological agents and immunomodulators may be available, which can lead to the reactivation or exacerbation of preexisting infectious diseases. This case report is about a 24-year-old female patient, diagnosed with Crohn's disease 10 years ago, evolving in need of treatment with Infliximab and, after a period of less than 1 year, she presented progressive odynophagia, abdominal pain and diarrhea, in addition to weight loss, night sweats and daily fever. Chest computer tomography showed a tree in bud, and the diagnosis of pulmonary tuberculosis was confirmed by the Rapid Molecular Test in the sputum and probable laryngeal and intestinal tuberculosis.

Tuberculosis laríngea secundaria a foco pulmonar primario inadvertido: caso clínico / Laryngeal tuberculosis secondary to an inadvertent primary pulmonary focus: clinical case

Introducción: La tuberculosis laríngea es una entidad sumamente rara en países del primer mundo, sin embargo, en nuestro medio no es extraño, como país latinoamericano, sospechar esta patología como una de las causas de disfonía y lesiones granulomatosas en la actualidad. La tuberculosis laríngea debe considerarse dentro de las patologías en pacientes con disfonía de larga evolución que no responden al tratamiento común, esta entidad puede ser confundida con neoplasias. Reporte de caso: Se presenta el caso de una mujer en la cuarta década de la vida con disfonía crónica de 6 meses de evolución, que fue remitida para laringoscopia. Se localizaron neoformaciones granulomatosas acompañadas de edema en ambas cuerdas vocales, sometidas a biopsia, con resultados con la tinción de hematoxilina-eosina de células gigantes multinucleadas de Langhans y la tinción Zielh-Nielsen fue positiva para bacilo alcohol ácido resistente. La radiografía de tórax mostró lesiones reticulonodulares sugestivas de tuberculosis pulmonar. Conclusión: Un alto nivel de sospecha y un diagnóstico temprano pueden limitar las complicaciones y facilitar un manejo oportuno de estos casos. Es necesario sospechar de tuberculosis laríngea en pacientes que presentan disfonía crónica, especialmente cuando se asocia con síntomas constitucionales, aunque no siempre los presentan, por otro lado, en algunos casos, no existe asociación con inmunodeficiencia.

Introduction: Laryngeal tuberculosis is an extremely rare entity in first world countries, however, it is not strange in our environment as a Latin American country to suspect this pathology as one of the causes of dysphonia and granulomatous lesions today. Laryngeal tuberculosis should be considered within the pathologies in patients with long-standing dysphonia that do not respond to common treatment, this entity can be confused with neoplasms. Case report: We present the case of a female in the fourth decade of life with chronic dysphonia of six months of evolution, who was referred for laryngoscopy, granulomatous neoformations accompanied by edema in both vocal cords were located, subjected to biopsy with results with hematoxylin staining. Langhans multinucleated giant cell eosin and Zielh-Nielsen staining were positive for acid-fast bacillus. Chest X-ray showed reticule-nodular lesions suggestive of pulmonary tuberculosis. Conclusion: A high level of suspicion and an early diagnosis can limit complications and facilitate timely management of these cases. It is necessary to suspect laryngeal tuberculosis in patients with chronic dysphonia, especially when associated with constitutional symptoms, although they do not always present them; on the other hand, in some cases, there is no association with immunodeficiency

Factors related to false negative results of interferon-γ release test in patients with confirmed pulmonary tuberculosis / 中华临床感染病杂志

Objective:To analyze the influencing factors related to false-negative results of interferon-γ release assay (IGRA) QFT-GIT in patients with confirmed pulmonary tuberculosis.Methods:Clinical data of 389 patients with bacteriologically confirmed pulmonary tuberculosis who underwent QFT-GIT in Quzhou Hospital Affiliated to Wenzhou Medical University between January 1 and December 31 2020 were retrospectively analyzed. Univariate and multivariate logistic regression were used to analyze the influencing factors related to the false-negative results of QFT-GIT.Results:Among 389 confirmed patients, 347 cases had positive QFT-GIT results and 42 cases had negative results. Univariate analysis showed that the false-negative results of QFT-GIT were associated with low BMI, reduced CD4 + T lymphocyte count, decreased lymphocyte count, increased C-reactive protein, negative sputum smear, anemia, diabetes mellitus, malignant tumor and sepsis ( P<0.05 or P<0.01). Multivariate conditional logistic regression analysis showed that BMI <18.5 kg/m 2( OR=1.585, 95% CI 1.076-2.336), complicated with diabetes( OR=5.157, 95% CI 2.340-11.365), malignant tumors ( OR=5.596, 95% CI 2.048-15.295)and sepsis ( OR=4.141, 95% CI 1.042-16.459) were independent risk factors for the false-negative results of QFT-GIT ( P<0.05 or P<0.01). Conclusion:When the pulmonary tuberculosis patients are extreme emaciation, complicated with diabetes, malignant tumor or sepsis, the QFT-GIT results will be false negative.
