Hemoptisis secundaria a tuberculosis pulmonar complicada con pseudoaneurisma de Rasmussen. Reporte de un caso en pediatría. / Hemoptysis in Pulmonary Tuberculosis Complicated by Rasmussen's Pseudoaneurysm. A Pediatric Case Report.

Presentamos el caso de un niño de 12 años que consultó por hemoptisis, sin otros sín- tomas asociados. Se realizó radiografía de tórax (patológica), laboratorio con aumen- to moderado de reactantes de fase aguda, PPD (negativa), esputos x 3 con bacilosco- pias negativas y tomografía de tórax con contraste i.v. que mostró imágenes de árbol en brote en todos los lóbulos y una imagen de dilatación vascular de una rama de la ar- teria pulmonar en lóbulo superior izquierdo. Se plantearon diagnósticos diferenciales: malformación vascular primaria o lesión secundaria a infección. La angiografía digital permitió confirmar el pseudoaneurisma y embolizarlo. Luego de 17 días, 2/3 cultivos de esputo fueron positivos para Mycobacterium tuberculosis. El niño realizó tratamiento antituberculoso con drogas de primera línea con evolución clínica favorable. Este caso resalta la importancia de considerar el pseudoaneurisma de Rasmussen en- tre las posibles complicaciones de un paciente con tuberculosis y hemoptisis recurren- te o masiva.

We present the case of a 12-year-old boy admitted to the hospital due to hemoptysis without other symptoms. We performed a Thorax X-Ray (pathological), laboratory with elevated acute phase reactants, TST (negative), sputum x 3 with negative smear and computed tomography angiography showing a tree-in-bud pattern in all lobes, and di-latation of a brunch of the pulmonary artery in the upper left lobe. We considered pri-mary vascular anomaly or lesion due to infection as a differential diagnosis. The patient underwent digital angiography and therapeutic embolization of this pseudoaneurysm. After seventeen days, 2/3 of the sputum cultures were positive for Mycobacterium tu-berculosis. The patient received standard anti-TB therapy with favorable evolution. This case highlights the importance of considering complications such as Rasmussen's pseudoaneurysm in patients with pulmonary tuberculosis and recurrent or massive hemoptysis.

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.

Prevalencia de infección tuberculosa latente e incidencia de viraje tuberculínico en contactos escolares mayores de 5 años en la Ciudad Autónoma de Buenos Aires / Prevalence of latent tuberculosis infection and incidence of tuberculin conversion among school contacts older than 5 years in the City of Buenos Aires

Introducción. La tuberculosis continúa siendo un problema frecuente en contextos de vulnerabilidad socioeconómica. El objetivo principal fue establecer la prevalencia de infección latente y viraje tuberculínico en contactos escolares de casos de tuberculosis. Población y métodos. En un área programática del sur de la ciudad, se evaluó la prevalencia de infección y viraje tuberculínico de 691 niñas, niños y adolescentes utilizando la prueba cutánea de tuberculina. Se investigó la asociación entre pérdida de seguimiento por parte del equipo de salud y características demográficas, escolares y asistencia inicial, y se describió el grado de adherencia cuando la quimioprofilaxis con isoniacida fue indicada. Resultados. Según las definiciones consideradas, la prevalencia de infección latente fue entre el 3,4 % (IC95 %: 2,3-5,2) y el 11,6 % (IC95 %: 9,3-14,4) de los 610 contactos con al menos una prueba cutánea aplicada. La incidencia de viraje tuberculínico se encontró entre el 0,3 % y el 6,8 % de los 294 evaluados. La edad mayor de 18 años, la mayor prevalencia de necesidades básicas insatisfechas en la comuna escolar, la pertenencia al turno escolar vespertino, la negatividad en la baciloscopia del caso índice y la ausencia de aplicación de la prueba cutánea inicial se asociaron con pérdida de seguimiento del contacto. Conclusiones. La incidencia de viraje tuberculínico en contactos escolares fue baja. La adherencia a isoniacida continúa siendo limitada. Se identificaron factores asociados con la pérdida de seguimiento de contactos que podrían orientar estrategias necesarias para mejorar este proceso.

Introduction. Tuberculosis continues to be a common problem in settings of socioeconomic vulnerability. Our primary objective was to establish the prevalence of latent infection and tuberculin conversion among school contacts of tuberculosis cases. Population and methods. In a programmatic area in the south of the City of Buenos Aires, the prevalence of latent infection and tuberculin conversion was assessed in 691 children and adolescents using the tuberculin skin test. The association between loss to follow-up by the health care team and the demographic, school, and baseline care characteristics was studied, and the level of adherence when isoniazid chemoprophylaxis was indicated was described. Results. According to established definitions, the prevalence of latent infection was between 3.4% (95% confidence interval [CI]: 2.3­5.2) and 11.6% (95% CI: 9.3­14.4) in the 610 contacts with at least one skin test. The incidence of tuberculin conversion was between 0.3% and 6.8% in the 294 assessed participants. Age older than 18 years, a higher prevalence of unmet basic needs in the school district, attending the afternoon school shift, negative sputum smear results in the index case, and absence of baseline skin test were associated with contact lost to follow-up. Conclusions. The incidence of tuberculin conversion among school contacts was low. Adherence to isoniazid treatment remains limited. Factors associated with loss of contact tracing were identified, which may guide strategies necessary to improve this process.

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.

Introducción: La tuberculosis pulmonar es uno de los problemas de salud pública más importante a nivel mundial. El personal de la salud tiene mayor probabilidad de contraer la infección con Mycobacterium tuberculosis por su exposición incrementada a pacientes con la enfermedad. Objetivo: Sistematizar el control de la tuberculosis pulmonar en el personal de enfermería en instituciones hospitalarias. Métodos: Revisión integrativa en las bases de datos SciELO y Medline, mediante los descriptores (DeCS): "tuberculosis/tuberculose", "Personal de Enfermería/pessoal de enfermagem/health personnel", "prevención/prevencao/prevention", a través de los operadores booleanos AND y OR. Se establecen las categorías de análisis para una mejor organización del conocimiento. Se establecieron como criterios de inclusión, artículos completos en español, portugués e inglés, que refirieran de manera clara la metodología y los resultados obtenidos. Se incluyeron 10 referencias, que evidencian que existen diversos factores para la transmisión del bacilo de la tuberculosis, en el personal de atención en salud, como el número de pacientes con tuberculosis pulmonar atendidos al año. Es esencial la concientización de las medidas para su control. Diversas publicaciones documentan experiencias de la aplicación de medidas de control, con sus respectivas recomendaciones, mediante el análisis de sus ventajas, desventajas y en algunos casos, de su rentabilidad. Conclusiones: Las evidencias científicas exponen que las medidas de control de la tuberculosis en las instituciones hospitalarias son una estrategia eficaz para prevenir la transmisión de la enfermedad al personal de enfermería(AU)

Introduction: Pulmonary tuberculosis is one of the most important public health problems worldwide. The healthcare personnel are more likely to contract infection with Mycobacterium tuberculosis, because of their increased exposure to patients with the disease. Objective: To systematize the control of pulmonary tuberculosis among the nursing personnel in hospital institutions. Methods: An integrative review in the SciELO and Medline databases was carried out, using the Health Sciences Descriptors (DeCS) tuberculosis/tuberculose [tuberculosis], Personal de Enfermería/pessoal de enfermagem/health personnel [nursing personnel], prevención/prevenção/prevention, through the Boolean operators AND and OR. The analysis categories were established for better knowledge organization. The established inclusion criterions were complete articles published in Spanish, Portuguese and English, which clearly referred to the methodology and obtained results. Ten references were included, showing that there are several factors for the transmission of the tuberculosis bacillus in the health care personnel, as being the number of patients with pulmonary tuberculosis attended per year. Awareness-raising is essential concerning measures for its control. Publications document experiences regarding the application of control measures, with their respective recommendations, by analyzing their advantages, disadvantages and, in some cases, their cost-effectiveness. Conclusions: Scientific evidence show that tuberculosis control measures in hospital institutions are an effective strategy for preventing transmission of the disease to nursing personnel(AU)

Acceptability of hair harvest as a method of tuberculosis therapeutic drug monitoring among adult pulmonary TB patients: a qualitative study

Background: The current six months regimen for drug-susceptible tuberculosis (TB) is long, complex, and requires adherence monitoring. TB hair drug level assay is one innovative approach to monitor TB treatment adherence however, its acceptability in the context of African multi-cultural settings is not known. Objective: To determine the acceptability of hair harvest and testing as a TB therapeutic drug monitoring method. Methods: The study explored perceptions, and lived experiences among TB patients with regard to using hair harvest and testing as a method of tuberculosis therapeutic drug monitoring in the context of their cultural beliefs, and faith. We used a descriptive phenomenological approach. Results: Four main themes emerged namely: participants' perceptions about the cultural meaning of their body parts; perceptions about hair having any medical value or meaning; perceptions about hospitals starting to use hair harvest and testing for routine hospital TB treatment adherence monitoring; and perceived advantages and disadvantages of using hair for treatment adherence monitoring. Overall, we found that using hair to monitor adherence was acceptable to TB patients provided the hair was harvested and tested by a medical worker. Conclusion: Hair harvest for medical testing is acceptable to TB patients on the condition that it is conducted by a medical worker

Preferred techniques of hair harvest for medical testing among adult pulmonary TB patients

Background: Antiretroviral hair drug levels are currently being used to monitor adherence to HIV treatment. There is currently a dearth of literature on the preferred technique(s) of hair harvest for medical testing in the context of African multicultural settings. Objective: To explore the preferred techniques(s) of hair harvest for medical testing among TB patients. Methods: We used a descriptive phenomenological approach to conduct interviews for 15 TB patients from the 06th through the 24th of June 2022. Data was organized by N-VIVO version 10 and analysed step by step using a thematic analytical approach. Results: Participants aged <30 years were more knowledgeable, positively perceived, and experienced about the salon-based hair cutting technique compared to those aged≥30 years old. Participants aged ≥30 had experience, flexibility to use, and were knowledgeable in all three techniques, Overall, for all age categories (<30,30-40 and >40 years), majority of the respondents were knowledgeable, flexible and experienced in using all the three techniques. Conclusion: The majority of TB patients were knowledgeable, experienced and flexible about the hair cutting techniques however, efforts are needed to educate the youth that hair for medical testing can be cut by any of the three techniques without changing their cosmetic look.

Reativação de Tuberculose Pulmonar em uma Paciente com Câncer de Orofaringe Tratada com Nivolumabe: Relato de Caso / Reactivation of Pulmonary Tuberculosis in a patient with Oropharyngeal Cancer Treated with Nivolumab: Case Report

Os inibidores de checkpoints imunológicos (ICI) são uma classe de medicamentos cada vez mais utilizados para tratar o câncer. No entanto, eles têm sido associados a um risco aumentado de reativação da tuberculose (TB) em pacientes com infecção tuberculosa latente (ILTB). Relato do caso: Mulher, 61 anos, com câncer de orofaringe desenvolveu reativação de TB pulmonar enquanto recebia nivolumabe. Acredita-se que a reativação da TB em pacientes em ICI seja em virtude da inibição da via PD-1 que desempenha um papel no controle da ILTB. A incidência de reativação da TB em pacientes em ICI é maior do que na população geral. Conclusão: O uso crescente de ICI provavelmente levará a um aumento no número de casos de reativação da TB. Sugere-se proceder ao rastreamento rotineiro para ILTB nos pacientes que estão sendo considerados para tratamento com ICI, especialmente em países com alta incidência de TB.

Post-tuberculosis lung disease and chronic obstructive pulmonary disease / 中华医学杂志(英文版)

The burden of chronic airway diseases, including chronic obstructive pulmonary disease (COPD), continues to increase, especially in low- and middle-income countries. Post-tuberculosis lung disease (PTLD) is characterized by chronic lung changes after the "cure" of pulmonary tuberculosis (TB), which may be associated with the pathogenesis of COPD. However, data on its prevalence, clinical manifestations, computed tomography features, patterns of lung function impairment, and influencing factors are limited. The pathogenic mechanisms underlying PTLD remain to be elucidated. This review summarizes the recent advances in PTLD and TB-associated COPD. Research is urgently needed both for the prevention and management of PTLD.

Epidemiological characteristics and spatio-temporal distribution of pulmonary tuberculosis cases reported in students from Guizhou Province, 2011-2020 / 中华流行病学杂志

Objective: To analyze the trend of epidemiological characteristics and spatiotemporal distribution of pulmonary tuberculosis (PTB) among smear-positive or other types of students in Guizhou Province from 2011 to 2020, and to provide a reference for improving prevention and control measures. Methods: Data were collected from the Chinese Information System's Notifiable Disease and Tuberculosis Management Information System for disease control and prevention, the Joinpoint 4.9.1.0 software was used to analyze the trend of registration rate; the ArcGIS 10.6 software was used to construct a ring map and to perform spatial autocorrelation analysis; the SaTScan 9.7 software was used for spatial-temporal scan statistics. Results: A total of 32 682 student PTB cases were reported in Guizhou Province from 2011 to 2020, including 5 949 (18.20%) smear-positive cases. Most cases occurred from high school students of 16 to 18 years old (43.99%, 14 376/32 682); the annual average registered rate was 36.22/100 000, the highest in 2018 (52.90/100 000), and the registration rate showed an increasing trend. Meanwhile, a similar trend of registration rate was observed among smear-positive or other types of students. The spatialtemporal heterogeneity was found that the "high-high" clustering patterns of smear-positive or other types were aggregated in Bijie City. Six spatialtemporal clusters with statistically significant (all P<0.001) were detected among smear-positive or other cases, respectively. Conclusions: Upward trend with spatial- temporal clusters of PTB cases reported in students from Guizhou Province from 2011 to 2020. Surveillance should be strengthened for high school students, and regular screening should be conducted in high-risk areas to control the source of infection and reduce the risk of transmission.

Analysis of tuberculosis epidemiological characteristics and drug resistance among the floating population in Beijing in 2019 / 中华流行病学杂志

Objective: To analyze the epidemic characteristics and drug resistance of pulmonary tuberculosis among the floating population in Beijing and to provide a scientific basis for formulating strategies for the prevention and control of tuberculosis among the floating population. Methods: Data of tuberculosis patients who were positive for Mycobacterium tuberculosis culture was collected from 16 districts and one municipal institution of tuberculosis control and prevention in Beijing in 2019. The strain samples were tested for drug sensitivity by the proportional method. According to household registration location, patients were divided into the floating population and Beijing registration. SPSS 19.0 software analyzed tuberculosis patients' epidemic characteristics and drug resistance in the floating population. Results: In 2019, there were 1 171 culture-positive tuberculosis patients in Beijing, among the floating population, 593 (50.64%) patients were identified, with a male-to-female sex ratio of 2.2∶1 (409∶184). Compared to patients under household registration as Beijing residents, a higher proportion of young adults aged 20-39 years (65.09%,386/593) were noticed, with 55.65% (330/593) reported from the urban areas and 96.80% (574/593) were reported the first time. The differences were statistically significant (all P<0.05). After completing the drug sensitivity test, 37 cases were with multiple drug-resistant tuberculosis, accounting for 6.24% (37/593). The rates of isoniazid resistance (42.11%,8/19) and multidrug resistance (21.05%,4/19) in floating population patients after retreatment were significantly higher than those in newly treated patients (11.67%, 67/574 and 5.75%, 33/574), and the differences were statistically significant (all P<0.05). Conclusions: Most patients with tuberculosis in the floating population in Beijing in 2019 were young males aged 20-39 years. The reporting areas were urban areas and the newly treated patients mainly. The patients with tuberculosis in the re-treated floating population were more likely to suffer from multidrug and drug resistance, which should be taken as the key population for prevention and control.

Changes in Notified Incidence of Pulmonary Tuberculosis in China, 2005-2020 / 生物医学与环境科学（英文）

OBJECTIVE@#To evaluate the trend of notified incidence of pulmonary tuberculosis (PTB) in China at different periods by population and region and to explore the effect of TB prevention and control in recent years.@*METHODS@#Using pooled data on TB cases reported by the TB Information Management Reporting System (TBIMS) from 2005 to 2020, we calculated the annual percentage change (APC) using the Joinpoint regression model.@*RESULTS@#From 2005 to 2020, a total of 16.2 million cases of PTB were reported in China, with an average notified incidence of 75.5 per 100,000 population. The age standardization rate (ASR) continued to decline from 116.9 (/100,000) in 2005 to 47.6 (/100,000) in 2020, with an average annual decrease of 5.6% [APC = -5.6, 95% confidence interval ( CI): -7.0 to -4.2]. The smallest decline occurred in 2011-2018 (APC = -3.4, 95% CI: -4.6 to -2.3) and the largest decrease in 2018-2020 (APC = -9.2, 95% CI: -16.4 to -1.3). From 2005 to 2020, the ASR in males (159.8 per 100,000 in 2005, 72.0 per 100,000 in 2020) was higher than that in females (62.2 per 100,000 in 2005, 32.3 per 100,000 in 2020), with an average annual decline of 6.0% for male and 4.9% for female. The average notified incidence was the highest among older adults (65 years and over) (182.3/100,000), with an average annual decline of 6.4%; children (0-14 years) were the lowest (4.8/100,000), with an average annual decline of 7.3%, but a significant increase of 3.3% between 2014 and 2020 (APC = 3.3, 95% CI: 1.4 to 5.2); middle-aged (35-64 years) decreased by 5.8%; and youth (15-34 years) decreased by an average annual rate of 4.2%. The average ASR in rural areas (81.3/100,000) is higher than that in urban areas (76.1/100,000). The average annual decline in rural areas was 4.5% and 6.3% in urban areas. South China had the highest average ASR (103.2/100,000), with an average annual decline of 5.9%, while North China had the lowest (56.5/100,000), with an average annual decline of 5.9%. The average ASR in the southwest was 95.3 (/100,000), with the smallest annual decline (APC = -4.5, 95% CI: -5.5 to -3.5); the average ASR in the Northwest China was 100.1 (/100,000), with the largest annual decline (APC = -6.4, 95% CI: -10.0 to -2.7); Central, Northeastern, and Eastern China declined by an average of 5.2%, 6.2%, and 6.1% per year, respectively.@*CONCLUSIONS@#From 2005 to 2020, the notified incidence of PTB in China continued to decline, falling by 55%. For high-risk groups such as males, older adults, high-burden areas in South, Southwest, and Northwest China, and rural regions, proactive screening should be strengthened to provide timely and effective anti-TB treatment and patient management services for confirmed cases. There is also a necessity to be vigilant about the upward trend of children in recent years, the specific reasons for which need to be further studied.

Influencing factors of the adverse outcome of pulmonary tuberculosis among adolescents in Hangzhou City between 2005 and 2020: a school-based retrospective cohort study / 中华预防医学杂志

Objective: To explore the influencing factors of the adverse outcome of pulmonary tuberculosis (PTB) among adolescents in Hangzhou City between 2005 and 2020. Methods: A retrospective cohort study was used to collect the information of adolescent PTB patients with the onset of PTB occurring from January 1, 2005 to December 31 in 12 designated tuberculosis hospitals in Hangzhou, mainly including demographic, epidemiological, clinical manifestations, bacteriological characteristics and other data, through the China Management Information System for Infectious Disease Surveillance and Reporting and the follow-up survey. All patients were followed up and the end time was December 31, 2021. Multivariate Cox regression model was used to analyze the factors affecting the adverse outcome of these patients. Results: The mean age of 4 921 adolescent PTB patients was (18.9±3.6) years old, and the number of male and female patients were 3 074 and 1 847 respectively. The adverse outcome accounted for 14.7% (725) of all patients. Multivariate Cox regression model showed that eight risk factors, including management model from patients themselves or family members (HR=5.87, 95%CI: 4.55-7.64), molecular biology examination positive for PTB (HR=4.62, 95%CI: 2.98-7.19), the number of sputum smears-positive≥1 (HR=3.72, 95%CI: 2.87-4.83), non-standardized therapy regimens of PTB (HR=3.69, 95%CI: 2.95-4.64), history of retreated PTB (HR=2.22, 95%CI: 1.46-3.36), migrant adolescents (HR=1.89, 95%CI: 1.54-2.34), the number of chest X-ray scan (HR=1.83, 95%CI: 1.65-2.04), and severe PTB (HR=1.38, 95%CI: 1.02-2.05), were associated with the adverse outcome of adolescent PTB patients. Age (HR=0.94, 95%CI: 0.92-0.96), as the only protective factor, was associated with the adverse outcome of these patients. Conclusion: The management mode, molecular biological examination, chemotherapy program, history of tuberculosis, sputum smear examination, severity of tuberculosis, household residence, chest X-ray examination and age are associated with the adverse outcomes of adolescent PTB patients in Hangzhou.

Tuberculosis pulmonar con baciloscopía positiva en pacientes inmunocomprometidos. Hospital de Clínicas, 2018-2019 / Smear-positive pulmonary tuberculosis in immunocompromised patients. Hospital de Clínicas, 2018-2019

Introducción: La tuberculosis representa la novena causa de muerte en todo el mundo. La infección latente puede reactivarse por situaciones que comprometan la inmunidad del huésped. La tuberculosis pulmonar es la manifestación más frecuente en pacientes inmunodeprimidos. La baciloscopia es la herramienta primaria en el diagnóstico de la tuberculosis pulmonar activa. Objetivos: Determinar la frecuencia de tuberculosis pulmonar con baciloscopia positiva en pacientes inmunocomprometidos que acuden al Servicio de Neumología del Hospital de Clínicas durante el periodo 2018 a 2019. Materiales y métodos: Diseño observacional, descriptivo, transversal, retrospectivo, muestreo no probabilístico de casos consecutivos. Se realizó la revisión de fichas clínicas de pacientes internados en la Cátedra de Neumología del Hospital de Clínicas (2018-2019), registrados en la estadística del servicio. Para el procesamiento y análisis de datos fue utilizada una planilla electrónica precodificada de Microsoft Excel. Resultados: Del total de historias clínicas de pacientes dentro de la población estudiada (n=34), en el 68% de los casos el diagnóstico se estableció mediante baciloscopia, el 65% de ellos con hallazgo tres cruces (+++). Conclusión: La frecuencia de baciloscopia positiva en inmunocomprometidos determinada fue elevada. Aunque se está disminuyendo su uso, es importante seguir practicando este estudio a todos los inmunocomprometidos con síntomas respiratorios debido a su bajo costo y practicidad.

Introduction: Tuberculosis represents the ninth leading cause of death worldwide. Latent infection can be reactivated by situations that compromise host immunity. Pulmonary tuberculosis is the most frequent manifestation in immunocompromised patients. Smear microscopy is the primary tool in the diagnosis of active pulmonary tuberculosis. Objectives: To determine the frequency of smear-positive pulmonary tuberculosis in immunocompromised patients attending the Pneumology Service of the Hospital de Clínicas during the period 2018 to 2019. Materials and methods: Observational, descriptive, cross-sectional, retrospective, non-probabilistic sampling of consecutive cases. A review of clinical records of patients admitted to the Department of Pneumology of the Hospital de Clínicas (2018-2019), registered in the statistics department of the service, was performed. A pre-coded Microsoft Excel spreadsheet was used for data processing and analysis. Results: Of the total patient medical records within the studied population (n=34), in 68% of the cases the diagnosis was established by smear microscopy, 65% of them with finding three crosses (+++). Conclusion: The frequency of positive smear microscopy in immunocompromised patients was high. Although its use is decreasing, it is important to continue performing this study in all immunocompromised patients with respiratory symptoms due to its low cost and practicality.
