RESUMO
Objective To conduct a retrospective cohort study on the influencing factors of poor prognosis of young and middle-aged patients with pulmonary tuberculosis. Methods Selecting 426 young and middle-aged patients who were diagnosed with pulmonary tuberculosis in our hospital from January to December 2018 as the research subjects. Collecting the social demography information of all patients and the information of potential factors affecting the prognosis (allergy history, smoking history, drinking history, BMI level, disease information, treatment information, etc.) and discussing the factors affecting the prognosis of young and middle-aged pulmonary tuberculosis patients and their effects. Results The average age of 426 patients was (41.93±5.17) years old, the average BMI of them was (21.97±3.15) kg/m2, and an average course of disease of them was (2.76±0.99) years. There was no significant difference in the basic sexual information between men and women. In this study, a total of 128 patients with poor prognosis were retrospectively followed up, including 90 males and 38 females. The detection rate of males was significantly higher than that of females (χ2=16.976, P2=18.850, P2=38.924, P2=127.207, P2=32.566, P2=16.715, P2=17.315, P2=16.976，P1 and P1 and P<0.05; Regular treatment still showed potential protective factors, with an HR of 0.408, P<0.05. Conclusion: Male, emaciated body type, disease course ≥ 5 years, smoking history, number of lung field lesions ≥ 3, presence of pulmonary cavities and comorbidities are potential risk factors, while regular treatment suggests potential protective factors. Conclusion More targeted disease control and management should be implemented for middle-aged and young patients with pulmonary tuberculosis based on the aforementioned influencing factors to improve their prognosis.
RESUMO
Objectives To analyze the spatial and temporal aggregation of multidrug resistant pulmonary tuberculosis (MDR-TB) incidence in Nanning at the township / street scale from 2017 to 2021, to explore the spatial and temporal characteristics of the spread of MDR-TB in Nanning, and to provide a scientific reference basis for the health administrative departments to achieve the precise implementation of MDR-TB prevention and control. Methods Based on the data of MDR-TB cases in Nanning from 2017 to 2021, the spatial-temporal scanning analysis software SaTScan v9.7 was used to retrospectively detect and analyze the areas where MDR-TB cases gathered. Results Through simple spatial scanning analysis, it was found that there were three first-class aggregation areas (the aggregation center was Fujiayuan Street, Jiangnan District, 2017, Xinyang Street, Xixiangtang District, 2019, and Zhonghe Town, Yongning District, 2020), and one second-class aggregation area (the aggregation center was Jinchai Town, Mashan County, 2020). Simple time scanning showed that the clustering occurred from May 2019 to December 2020. Temporal and spatial aggregation analysis showed that Xinyang Street in Xixiangtang District was the center of the first-class aggregation area, Zhonghe Town in Yongning District was the center of the second-class aggregation area, and Jinchai Town in Mashan County was the center of the third-class aggregation area. Conclusion The multidrug resistant pulmonary tuberculosis epidemic in Nanning is distributed in an aggregated manner, especially in Xinyang Street, Xixiangtang District, which has the highest spatial and temporal aggregation. It is necessary to focus on and take regional prevention and control measures to control the epidemic.
RESUMO
Objective: Correlate inflammatory mediators and biochemical parameters in patients with active pulmonary tuberculosis (TB) treated at a public hospital in São Luís, MA. Methods: This is a case-control study of patients with a positive diagnosis of active pulmonary TB. Serum samples from patients and the control group were collected for the clinical trials, and epidemiological data were collected through medical records and interviews. The control group consisted of healthy volunteers with no previous contact with TB cases, matched by age and sex to the clinical group. To measure inflammatory cytokines, we used the Human IL-6 ELISA Set and Human IFN-γ ELISA Set kits. Oxidative stress was measured by quantification of thiobarbituric acid reactive substances (TBARS) and nitric oxide (NO). In biochemistry, the levels of uric acid, antistreptolysin "O" (AEO), alanine aminotransferase (ALT), amylase, aspartate aminotransferase (AST), calcium, total cholesterol, gamma-glutamyl transferase (Gamma GT), glucose, alkaline phosphatase, high-density lipoprotein (HDL), C-reactive protein (CRP) and triglycerides were measured. Results: The clinical group consisted of 53 patients. There was a substantial decrease in IFN-γ (p<0.0001) and a significant increase in IL-6 (p<0.0001). TBARS production increased significantly (p= 0.0414). There was no significant difference in NO production (p= 0.3194). In biochemistry, there was a significant increase in ALT (p= 0.0072), AST (p= 0.0016), Gamma GT (p= 0.0011), alkaline phosphatase (p<0.0001), CRP (p<0. .0001) and triglycerides (p= 0.0343), and a significant decrease in calcium (p<0.0001).

RESUMO
Background and Aims: The host immune system plays an important role in the pathogenesis and defense mechanism of Mycobacterium tuberculosis (Mtb). This study aimed to explore the different changes in the immune system between smear-negative pulmonary tuberculosis (PTB) and smear-positive PTB patients. Materials and Methods: A total of 85 active PTB patients and 50 healthy adults were enrolled. The participants were divided into smear-negative PTB, smear-positive PTB, and control groups. Chest computed tomography (CT) and lymphocyte subgroup counts in peripheral blood were measured in all participants. Results: There were higher numbers of CD4 + T-cells, NK cells, and pulmonary cavities in the smear-positive PTB group, whereas the numbers of B-ells were significantly increased in the smear-negative PTB group. Conclusions: Smear-negative PTB showed fewer pulmonary cavities, mild inflammatory response, lower numbers of immune cells, and higher numbers of B- cells.
RESUMO
Background: Pulmonary tuberculosis is still a public health problem, and surveillance data analysis has not been done much. Recently a global pandemic of COVID-19 has the potential in disturbing TB elimination pro-grams and treatment. This study aims to comprehensively analyse the incidence rate (IR) and Case Fatality Rate (CFR) of pulmonary tuberculosis in East Java from 2015–2020 and during COVID-19 and the strategies for optimizing tuberculosis disease control. Methodology: The study analyzed annual surveillance data using an analytical descriptive design. The Varia-bles were analyzed with Spearman correlation with a level of evidence of 95% (p<0.05). Results: The prevalence of pulmonary tuberculosis in East Java fluctuated from 2015–2020. In 2020 and dur-ing the COVID-19 pandemic, the number of cases and morbidity rates increased. Statistic results confirm the presence of a significant correlation between the values of Incidence rate (IR) and Case Fatality rate (CFR) (p = 0.032), IR and Treatment Success Rate (TSR) (p = 0.020), and CFR and TSR (p = 0.002). Population density is not correlated with the number of new cases (p = 0.667). Treatment rates have increased to 51%; cure and treatment rates have decreased to 76% and 89%, respectively, and there was a 4% increase in mortality dur-ing COVID-19. Conclusions: COVID-19 has tremendously affected the treatment of pulmonary TB cases in East Java, Indone-sia by increasing the incidence rate and decreasing the fatality rate. The pandemic promotes fear in the com-munity to check their medical status and improve the quality of their health in East Java.
RESUMO
Background: Ca-125 is a large molecular-weight glycoprotein synthesized by different cells originating from the coelomic epithelium. Although classically it has been used to monitor the course of ovarian epithelial cancer, there are other established circumstances associated with high serum Ca -125 levels and pulmonary tuberculosis is one of them. Diagnosing pulmonary tuberculosis, which is not bacteriologically positive often very challenging. Because many procedures are available for such cases but they are of limited use because some of them are lengthy or expensive or need sophisticated equipment, highly skilled personnel, etc. Serum CA-125 is a rapid, relatively inexpensive investigation. Objective: The present study aimed to assess the role of CA-125 in distinguishing pulmonary TB from bacterial pneumonia. Methods: This analytical cross-sectional study was conducted in the Department of Medicine, Dhaka Medical College Hospital for the period of March 2018 to September 2020.100 pulmonary tuberculosis patients were taken in group I, and 100 bacterial pneumonia patients were taken in group II according to selection criteria. Informed written consent was taken from each of the participants. All were subjected to detail clinical and demographic history along with thorough physical examination. Relevant investigations were done including serum CA-125. All final data were collected in the semi-structured and pretested case record form. After data collection, data were checked for errors, and analysis was done. Results: In this study, the mean CA-125 value was 62.29 (SD±31.51) IU/mL in group I(pulmonary tuberculosis). In group II (bacterial pneumonia) mean value was 22.95(±8.25) IU/mL. The mean value of CA-125 was significantly higher (p-value <0.001) in group I patients compared to group II. About 59.0% of patients in group I had a high level of serum CA-125 which had a significant difference from group II (p<0.001). ROC analysis of CA-125 in the diagnosis of patients with active pulmonary tuberculosis showed a cut-off value of ?31.7 IU/mL had sensitivity, specificity, PPV, NPV, PLR, NLR, and accuracy of 72%, 87%, 84.7%, 75.7%, 5.54%, 0.321%, and 79.5% respectively. Conclusion: This study’s findings stated that serum CA-125 may be a useful marker in distinguishing PTB from bacterial pneumonia. Therefore, further study with a more generalized study population is recommended.
RESUMO
Diffuse cystic lung disease due to pulmonary tuberculosis (TB) is rare. We describe an 8-year-old boy who presented with acute onset respiratory distress while on a compliant anti-tubercular treatment for a recently diagnosed pulmonary TB. On clinical examination, hypoxemia, clubbing, and features of the right-sided heart failure were observed. High-resolution computed tomography of the chest revealed extensive cystic lung parenchymal changes with ground glassing and consolidation, and echocardiography indicated the presence of pulmonary arterial hypertension. His treatment included supplemental oxygen, sildenafil, prednisolone, and anti-tubercular drugs. At the two-year follow-up, the patient showed complete clinical recovery and resolution of cysts on the chest X-ray.
RESUMO
Addison's disease is a rare endocrinal disorder that was first described by Thomas Addison in 1855. Addison抯 disease occurs as a result of a lack of production of adrenocortical hormones, which is a rare but fatal disease if left untreated. The two most common causes of Addison's disease are autoimmune adrenalitis and tuberculosis which refer to hypoadrenalism caused by total or near total destruction or dysfunction of both adrenal cortices. Usual manifestations involve chronic fatigue, muscle weakness, loss of appetite, nausea, vomiting, diarrhoea, hypotension, and hyper pigmentation of the skin. A substantial proportion of patients presenting with extra-pulmonary tuberculosis (TB) have urogenital TB (UG-TB), which is easily under diagnosed because of non-specific symptoms, which are chronic and have cryptic protean clinical manifestations. Most of the clinician are not aware of the possibility of UG � TB. Calcification of seminal vesicle found in this case is a rare condition, which is commonly associated with diabetes, hyperparathyroidism, and genitourinary tuberculosis. We here in report a rare case of adrenal insufficiency due to miliary tuberculosis involving adrenal gland, old pulmonary tuberculosis and genitourinary tuberculosis (seminal vesicles calcification) in a 31 year old male person. He presented with multiple episodes of vomiting, and giddiness which wasalso accompanied with atypical hyperpigmentation. His symptoms resolved after starting anti tuberculous therapy.
RESUMO
We reported a case of a patient dignosed as tuberculosis and severe malnutrition with coronavirus disease 2019 （critical type） treated with a combination of Chinese medicine and Western medicine. Through the retrospective analysis of the diagnosis and treatment process of this patient， on the basis of Chinese medicine's understanding of the etiology and pathogenesis of “old state” and “deficient state”， the critical coronavirus pneumonia combined with pulmonary tuberculosis and severe malnutrition was mostly due to the physical condition and the invasion of epidemic toxin， resulting in dysfunctions of the internal organs such as the lungs， spleens， kidneys and other organs. Based on the understanding of the cause and mechanism of the coronavirus disease， the treatment combined Chinese and Western medical therapies was given. The western medicine was used with the main treatments of oxygen therapy， anti-viral， intestinal nutritional support， and anti-coagulation， while the Chinese medicine was used by tonifying qi， blood， yin， and yang， warming yang and dissipating cold， and clearing heat and dampness， then tonifying qi， nourishing yin and eliminating heat， in which tonifying middle and replenishing qi ran through the whole process. The integrated treatment eventually improved the patient's symptoms and accelerated the negative conversion of nucleic acid of the coronavirus.
RESUMO
Objective To establish a prediction model for tuberculosis incidence in Nantong area by multivariate regression analysis, and to provide theoretical support for the implementation of combined prevention work in this area. Methods A total of 37 338 registered patients with pulmonary tuberculosis in Nantong City from 2010 to 2021 were enrolled in the observation group. A total of 28,721 healthy people who underwent physical examination during the same period were selected as the control group. Results From 2010 to 2021, there were a total of 37 338 cases of pulmonary tuberculosis in central Nantong. From 2010 to 2015, more than 3,000 cases were reported annually, with the largest number (4 142 cases) in 2011, accounting for 11.09% of the total. The number of cases reported from 2016 to 2021 was all less than 3 000, and the number of cases reported from 2021 was the least , 1 803 cases, accounting for 4.83% of the total. The number of cases decreased each year in the past 12 years. The incidence of pulmonary tuberculosis in males was 70.97% (26 497 cases) and that in females was 29.03% (10 841 cases). In terms of age, the lowest incidence rate was 0.06% (23 cases) in the age group of 0-9 years old, and the highest incidence rate was 19.56% (7 304 cases) in the age group of 60-69 years old. Logistics regression analysis showed that male, age ≥60 years old, occupation as a farmer and smoking history were the risk factors for pulmonary tuberculosis (P < 0.05). ROC curve results showed that the AUC value of the risk prediction model for pulmonary tuberculosis in the Nantong area was 0.872, with a predictive sensitivity of 86.32% and a specificity of 89.21%. Conclusion There are many risk factors for pulmonary tuberculosis in Nantong area, and different factors interact and influence each other. The construction of a risk prediction model for pulmonary tuberculosis can better predict the clinical incidence, which is helpful to guide clinical diagnosis and treatment.

RESUMO
Objective To investigate the clinical characteristics of drug-induced liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients with hepatitis B virus (HBV). Methods A total of 133 patients with pulmonary tuberculosis and HBV who were treated in Zhuzhou Central Hospital from January 2018 to early January 2022 were selected, and all were treated with conventional anti-tuberculosis 2HRZE/4HR regimen. According to the liver injury, the patients were divided into liver injury group and no liver injury group. Univariate analysis was used to analyze the related factors of liver injury caused by anti-tuberculosis drugs, and multivariate logistic regression analysis was used to analyze the independent risk factors of liver injury caused by anti-tuberculosis drugs. Results Among 133 cases of newly treated pulmonary tuberculosis patients with HBV, 24 cases had liver injury caused by anti-tuberculosis drugs, accounting for 18.05%; 109 patients had no liver injury caused by anti-tuberculosis drugs, accounting for 81.95%. Univariate analysis showed that there were significant differences in smoking history, drinking history, diabetes history, hypertension history, anti-tuberculosis treatment plan, malnutrition, and use of hepatoprotective drugs between the liver injury group and the no liver injury group (P<0.05). Multivariate logistic regression analysis showed that smoking history, drinking history, diabetes history, hypertension history, PZA-containing regimen, malnutrition, and no use of hepatoprotective drugs were independent risk factors for liver injury caused by anti-tuberculosis drugs. Conclusion Smoking history, drinking history, diabetes history, hypertension history, PZA-containing regimen, malnutrition, and no use of hepatoprotective drugs are the risk factors for drug-induced liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients with HBV.
RESUMO
Clinical data were retrospectively reviewed for one case of penicillium marneffei infection after renal transplantation (RT) to explore a proper management of peniciliosis marneffei (PSM)transplantation.This case had a history of pulmonary tuberculosis and underwent RT due to uremia.After discharging, postoperative recovery was excellent.Recurrent cough occurred at Month 7 post-operation.Fiberoptic bronchoscopy and pulmonary CT indicated a possibility of pulmonary tuberculosis.However, a definite diagnosis of PSM was confirmed by next generation sequencing (NGS) and pathogenic bacteria culture of alveolar lavage fluid.After adjusting immunosuppressive agents and regular antifungal treatment with voriconazole, respiratory symptoms improved and pulmonary CT hinted at a resorption of lesion.Features of pulmonary CT and bronchoscopic examination were nearly similar to those of tuberculosis.Thus early bacterium culture and NGS may aid an definite diagnosis.Voriconazole is an effective treatment of the disease.
RESUMO
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.
RESUMO
Objective To analyze the clinical characteristics of patients with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) and pulmonary tuberculosis, and investigate their survival and influencing factors of survival. Methods A total of 107 patients with HIV/AIDS and pulmonary tuberculosis were selected. The relationships of clinical symptoms, CT findings and CD4 cell count with positive laboratory tests were analyzed. Th survival of patients was investigated, and independent risk factors for death were analyzed. Results Most the 107 patients had symptoms such as cough, chest pain and fatigue. CT findings mainly included patchy shadow (75.70%), tree-in-bud sign (46.73%), nodular shadow (35.51%) and pulmonary hilar or mediastinal lymph node enlargement (86.92%). The proportion of lesions ≥ 3 pulmonary fields (47.66%) was higher. The positive rates of purified protein derivative (PPD), acid-fast bacilli and Mycobacterium tuberculosis were significantly higher in the CD4 cell count > 200/µL group than in the ≤200/µL group (P<0.05). There were statistically significant differences in body mass index (BMI), baseline CD4 cell count, multidrug resistant tuberculosis (MDR-TB) and standard anti-tuberculosis treatment between the survival group and the death group (P<0.05). Baseline CD4 cell count ≤200/µL, MDR-TB, and no standard anti-tuberculosis treatment were independent risk factors for death of patients with HIV/AIDS and pulmonary tuberculosis (P<0.05). Conclusion The clinical symptoms and imaging manifestations of patients with HIV/AIDS and pulmonary tuberculosis are complex and diverse, but characteristic. Baseline CD4 cell count ≤200/µL, MDR-TB and no standard anti-tuberculosis treatment are main risk factors for death of the patients.
RESUMO
Objective To analyze the epidemiological characteristics of pulmonary tuberculosis in the elderly people in Wuhan during 2016-2020, and to provide a basis for formulating effective prevention and control strategies and measures. Methods Using the National Tuberculosis Information Management System, a descriptive statistical analysis was performed on the medical records of elderly (≥60 years old) pulmonary tuberculosis patients registered in Wuhan from 2016 to 2020. Results A total of 9 427 elderly pulmonary tuberculosis patients were registered in Wuhan during 2016-2020, accounting for 32.07% of the total number of registrations in the whole population. The reported incidence rate of tuberculosis in the elderly was significantly higher than that in the total population, and the reported incidence rates in both the elderly and the general population showed declining trends (whole population χ2trend=216.97, P2trend=153.57, P<0.05). The time distribution showed that more cases occurred from April to November (70.90%). The top three districts with the largest number of registered cases were far urban areas, namely Huangpi District (13.81%), Xinzhou District (11.55%), and Jiangxia District (9.82%). The ratio of male to female with pulmonary tuberculosis in elderly patients was 2.85:1. Among the elderly pulmonary tuberculosis, the most registered cases were in the age group of 60 ~ years old, followed by 65 ~ years old. The proportion of smear-positive in elderly patients with pulmonary tuberculosis retreatment was 16.83%. Conclusion From 2016 to 2020, the epidemic situation of elderly pulmonary tuberculosis showed a downward trend in Wuhan. However, the elderly population with tuberculosis registrations still accounted for a relatively high proportion of the total population. According to the epidemiological characteristics of pulmonary tuberculosis among the elderly, the city should carry out tuberculosis prevention and control work in a timely, appropriate and focused manner.
RESUMO
Objective@#To analyze the epidemiological and clinical characteristics of pulmonary tuberculosis patients complicated by diabetes mellitus (PTB-DM), so as to provide insights into PTB-DM control.@*Methods@#The data pertaining to PTB cases in Quzhou City from 2016 to 2020 were extracted from Tuberculosis Information Management System of Chinese Disease Prevention and Control Information System. The demographic features, diagnosis and treatment of PTB-DM patients were descriptively analyzed, and compared with PTB patients.@*Results@#The incidence of PTB-DM was 6.79/105 to 9.27/105 in Quzhou City from 2016 to 2020, with an annual increase rate of 8.09%. Among all PTB-DM patients, there were 674 men (76.94%), 620 cases at ages of 60 years and older (70.78%), 564 cases living in urban areas (64.38%), 619 farmers (70.66%), 537 cases with delay in healthcare-seeking (61.30%), 802 treatment-naïve cases (91.55%), 547 cases positive for pathogenic tests (62.44%), 11 cases with rifampicin resistance (1.26%), 695 cases with negative conversion of sputum smears 2 months post-treatment (79.34%), and 783 cases with successful treatment (89.38%). The proportions of men, ages of 60 years and older, living in urban areas, farmers, delay in healthcare-seeking, positive pathogenic tests and rifampicin resistance were significantly higher among PTB-DM patients than among PTB patients, and the negative conversion rate of sputum smears 2 months post-treatment was significantly lower among PTB-DM patients than among PTB patients (all P<0.05).@*Conclusions@#The incidence of PTB-DM increased year by year in Quzhou City from 2016 to 2020, and PTB-DM cases were predominantly found among elderly men. The proportion of delay in healthcare-seeking, positive pathogenic tests and rifampicin resistance was higher among PTB-DM patients than among PTB patients.
RESUMO
@#Abstract: Objective To analyze the application effect of rapid diagnostic techniques in Shaanxi from 2016 to 2020,and to provide basis for further optimizing the process of tuberculosis detection and formulating prevention and control strategies. Methods A total of 104 437 cases of tuberculosis patients registered in Shaanxi Province from 2016-2020 were exported from the Tuberculosis Information Management System (The subsystem of China Disease Prevention and Control Information System) according to first management unit, and the laboratory test results of sputum smear, sputum culture and molecular tests were collected to statistically analyzed the positive rate of etiology, sputum smear, sputum culture, molecular biology testing rate, and indicators of positive testing rate of tuberculosis patients. Results From 2016 to 2020, the etiology�positive rate of tuberculosis in Shaanxi province were 13.49% (2 664/19 754), 22.68% (5 081/22 401), 35.99% (8 232/22 876), 48.14% (10 438 / 21 682), 52.65% (9 332 / 17 724), respectively, with an increasing trend (χ2 trend=9 473.12, P<0.001) year by year; the proportion of molecular tests positive only in etiology-positive pulmonary tuberculosis (PTB) were 0 (0/2 664), 0.16% (8/5 081), 15.44% (1 271/8 232), 27.58% (2 879/10 438), 31.52% (2 941/9 332), respectively, with an increasing trend year by year (χ2 trend=2 971.44, P<0.001); the molecular test rates of the 5 years were 0.01% (2 / 19 754), 0.38%(85 / 22 401), 21.11% (4 828/22 876), 52.42%(11 365/21 682), 55.18%(9 780/17 724), respectively, with an increasing trend year by year (χ2 trend = 28 269.23, P<0.001). The rate of molecular test in sputum smear-negative was 22.72%(17 976 / 79 130). The proportion of patients with only molecular test-positive was 33.43% (4 032/12 062) in municipal designated hospitals, and 11.99%(2 279/ 19 014) in county-level designated hospitals, the difference was statistically significant (χ2 =2 096.46, P<0.001). Conclusions The rate of molecular biology testing in Shaanxi Province from 2016 to 2020 showed a year-on-year increase. Through the application of rapid molecular tests, the etiology-positive rates of tuberculosis have been increased significantly,but the current molecular test detection rate is not high compared with other provinces, especially in county-level designated hospitals and smear-negative patients, so we should make a big promotion in application of rapid molecular technique.
RESUMO
ObjectiveTo describe the characteristics of treatment outcomes of multidrug-resistant tuberculosis （MDR-TB） patients enrolled in second-line treatment in Shanghai from 2017 to 2018， and to analyze the influencing factors of treatment outcomes. MethodsTotally 182 MDR-TB patients were analyzed by using data collected from the China tuberculosis management information system， the hospital's electronic medical record information system， whole genome sequencing results and a questionnaire survey， and logistic regression analysis was used to analyze the factors affecting the success of treatment. ResultsIn 182 MDR-TB patients， the success rate of treatment was 65.4%， the loss to follow-up rate was 8.2%， the mortality rate was 4.9%， the unassessable rate was 13.7%， and the drug withdrawal rate was 7.7%. The factors affecting the success of treatment in MDR-TB patients included age （35‒ years old， OR=5.28， 95%CI： 1.58‒17.59， P=0.007； 55‒ years old， OR=16.30， 95%CI： 4.36‒60.92， P<0.001） and compliance to medication （OR=0.55， 95%CI： 0.42‒0.72， P<0.001）. ConclusionThe treatment success rate of MDR-TB patients in Shanghai from 2017 to 2018 is significantly higher than the average level in China. Older patients and patients with less compliant are at higher risk of adverse treatment outcomes.
