Tuberculosis farmacorresistente y diabetes: estudio de casos y controles en un hospital peruano

Introducción: la tuberculosis farmacorresistente sigue siendo endémica y un importante problema de salud pública a nivel mundial, lo que resulta en una alta morbilidad. Las personas con diabetes son más susceptibles a las infecciones debido a la inmunosupresión, por lo que es importante reconocer los factores que predisponen a la tuberculosis farmacorresistente. Objetivo: identificar a la diabetes como factor asociado a la tuberculosis farmacorresistente en pacientes del Programa de prevención y control de la tuberculosis de un hospital peruano nivel II-2 del 2015 al 2021. Metodología: se realizó un estudio analítico de casos y controles, pareados por edad y sexo, se incluyó 66 pacientes con tuberculosis farmacorresistente (casos) y 198 pacientes con tuberculosis sensible (controles). Se utilizó la prueba de chi-cuadrado para el análisis bivariado y el cálculo del Odds Ratio. Se utilizó la regresión logística múltiple para el análisis multivariado. Resultados: el 9,1% de los casos y el 4% de los controles tenían diabetes, con OR 2,48 (IC 95% 0,68 - 8,47) y sin diferencias significativas. En el análisis multivariado, la diabetes fue estadísticamente significativa, aumentando el OR a 3,40 (IC 95% 1,01 - 11,49; p= 0,01). Conclusión: la diabetes se asoció con un mayor riesgo de tuberculosis farmacorresistente en pacientes del Programa de prevención y control de la tuberculosis en un hospital peruano nivel II-2.

Introduction: Drug-resistant tuberculosis continues to be endemic and a major public health problem worldwide, resulting in high morbidity. People with diabetes are more susceptible to infections due to immunosuppression, threfpre it is important to recognize the factors that predispose to drug-resistant tuberculosis. Objective: To identify diabetes as a factor associated with drug-resistant tuberculosis in patients of the Tuberculosis Prevention and Control Program of a level II-2 Peruvian hospital from 2015 to 2021. Methodology: An analytical case-control study was carried out, matched by age and sex, including 66 patients with drug-resistant tuberculosis (cases) and 198 patients with sensitive tuberculosis (controls). The chi-square test was used for the bivariate analysis and Odds Ratio calculation was also made. Multiple logistic regression was used for multivariate analysis. Results: 9.1% of the cases and 4% of the controls had diabetes, with OR 2.48 (95% CI 0.68 - 8.47) and without significant differences. In the multivariate analysis, diabetes was statistically significant, increasing the OR to 3.40 (95% CI 1.01 - 11.49; p= 0.01). Conclusion: Diabetes was associated with an increased risk of drug-resistant tuberculosis in patients of the Tuberculosis Prevention and Control Program at a level II-2 Peruvian hospital.

Changes of lymphocyte subsets in smear-negative pulmonary tuberculosis

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.

An Analysis of The Trend of Incidences and Fatality of Pulmonary Tuberculosis in East Java from 2015-2020: A Lesson From COVID-19

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.

Ca-125: A Useful Marker to Distinguish Pulmonary Tuberculosis from Bacterial Pneumonia

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.

An 8-year-old boy with diffuse cystic pulmonary tuberculosis: An intriguing story

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.

Miliary Tuberculosis with Addisons Disease - in old case of pulmonary tuberculosis, and tuberculosis of seminal vesicles - A rare case report

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.

O abandono do tratamento de tuberculose é uma questão relevante e preocu- pante na saúde pública mundial. Mediante uma revisão integrativa, esse estudo busca identificar os possíveis fatores que levam ao abandono do tratamento. Foi realizada pes- quisa em estudos indexados nas bases de dados: Biblioteca Virtual em Saúde (BVS) e Scientific Eletronic Library Online (SciELO), no período de 2017 a 2021, utilizando-se os seguintes descritores (DeCS): tuberculose, agente antituberculose e tuberculose pul- monar. Ao fim, foram selecionados onze estudos, publicados nos idiomas português, es- panhol e inglês. Os resultados mostraram que o abandono está relacionado a fatores de diversas esferas, com destaque para as esferas social, da saúde e a do próprio tratamento. Como perfil das pessoas dos casos de abandono, em geral, observou-se que elas são eco- nomicamente ativas, com faixa etária entre 15 e 49 anos, possuem baixa escolaridade, baixa renda e é comum que os usos abusivos de álcool e drogas sejam apresentados como comorbidades relevantes. Portanto, o trabalho evidenciou os principais fatores associados ao abandono do tratamento de tuberculose e a importância da participação de diferentes atores como forças que somarão para diminuir a ocorrência do problema em questão.

The abandonment of tuberculosis treatment is a relevant and worrisome issue in public health worldwide. Through an integrative review, this study seeks to iden- tify the possible factors that lead to treatment dropout. A search was carried out in studies indexed in the databases: Virtual Health Library (BVS) and Scientific Electronic Library Online (SciELO), from 2017 to 2021, using the following descriptors (DeCS): tuberculo- sis, antitubercular agentes and pulmonary tuberculosis.

Abstract Objectives to analyze the conceptions of people experiencing treatment and diagnosis of pulmonary tuberculosis. Method this is a descriptive and exploratory research with a qualitative approach, developed in a School Health Center of Belém (Pará) with 30 patients. Data was collected during the period from September 2019 to January 2020 through a semi-structured interview with the aid of a script containing six questions, as well as the observation of the information contained in the medical record and in the tuberculosis record control book. For the analysis of the results, the Content Analysis technique was used according to Bardin's perspective. Result it was identified that the reduced knowledge about the disease and the presence of negative conceptions influence, in a significant way, the search for care or the adherence to treatment, interfering in daily and work activities. Conclusion it is concluded that the need for patients to (re)mean tuberculosis during treatment persists, and it is essential that the health team knows such conceptions in order to provide care that contemplates physical and bio-psychosocial aspects before the Tuberculosis Control Program of the unit.

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.

An Unresolving Case of Pyomyositis: A Case Report

@#Pyomyositis which is also known as myositis tropicans is a rare condition where there is bacterial infection of the skeletal muscle. Its manifestation includes pain and tenderness of the affected muscle and general infective symptoms. It commonly occurs in immunocompromised individuals and patients with previous history of trauma to the affected muscle. We report a case of a 16-year-old boy with history of underlying bronchial asthma who presented with multiple abscesses. He underwent multiple operations to drain the infection and targeted antibiotic therapy subsequently. Despite undergoing surgical debridement, drainage and antibiotic treatment, he was still having repeated bouts of fever and his inflammatory markers were not reducing. He was then diagnosed with concurrent pulmonary tuberculosis infection which subjected him to an immunosuppressed state thus arising to the condition of pyomyositis and unresolving fever. The patient then made prompt improvement when the underlying cause of immunosuppression; pulmonary tuberculosis was treated as well.

Correlation of elevated serum exosomal miR-27a levels with drug resistance and adverse outcomes in pulmonary tuberculosis / 中国热带医学

@#Abstract: Objective To investigate the correlation of serum exosomal microRNA (exomiR)-27a with drug resistance and adverse outcomes in pulmonary tuberculosis (PTB), to provide new evidence for the development of anti-tuberculosis treatment. Methods From May 2018 to June 2020, 326 patients with PTB in the Eighth Affiliated Hospital of Xinjiang Medical University were selected and divided into 228 patients with active TB (active group) and 98 patients with latent TB infection (latent group), and 100 healthy subjects were included as controls. The serum exosomes of all subjects were extracted and identified by transmission electron microscopy, nanoparticle particle size analyzer and flow cytometry. The expression level of serum exomiR-27a was detected by real-time quantitative PCR. The diagnostic value of serum exomiR-27a in PTB was analyzed by receiver operating characteristic (ROC) curve. Drug resistance in patients with active PTB was recorded after standard treatment. The effect of serum exomiR-27a on the incidence of adverse outcomes was analyzed. Results The characterization of serum exosomes confirmed that exosomes were successfully isolated from serum. Compared with the control group 0.92(0.63, 1.17), the expression of serum exomiR-27a was up-regulated in the active group 1.55(1.18, 2.09) and the latent group 1.27 (0.96, 1.65), and the expression of exomiR-27a in the active group was higher than that in the latent group (P<0.05). PTB patients with high serum exomiR-27a expression (≥1.50) had poorer chest radiography and a higher proportion of chronic hepatitis comorbidities (P<0.05). ROC curve analysis showed that the area under the curve (AUC) of serum exomiR-27a distinguishing control and active group was 0.838 (95%CI: 0.795-0.880) and the AUC of serum exomiR-27a distinguishing normal and latent group was 0.766 (95%CI: 0.701-0.830). Patients in the active group received standard antituberculosis therapy (≥6 months). The expression level of serum exomiR-27a in drug-resistant patients was higher than that in sensitive patients (P<0.001), and the expression level of serum exomiR-27a in multi-drug resistant tuberculosis patients was higher than that in single-drug resistant tuberculosis patients (P<0.001). Logistic regression analysis showed that elevated serum exomiR-27a was an independent predictor of PTB resistance (P<0.001). High expression of serum exomiR-27a indicated a higher incidence of adverse outcomes (log rank=15.725, P<0.001). Conclusions High expression of serum exomiR-27a is helpful in the diagnosis and prediction of adverse outcomes of PTB.

Nutritional status of patients with pulmonary tuberculosis and anti-tuberculosis treatment effect / 中国热带医学

@#Abstract: Objective To investigate the nutritional status of patients with pulmonary tuberculosis and its effects on conventional anti-tuberculosis treatment, so as to provide a basis for improving the efficacy of conventional treatment of pulmonary tuberculosis. Methods The relevant data of 168 patients with pulmonary tuberculosis admitted to Suining Central Hospital from April 2020 to April 2022 were retrospectively analyzed. Nutritional status of the patients before treatment was investigated using the Mini Nutritional Assessment (MNA) score, and the influencing factors of nutritional status before treatment were analyzed. Therapeutic effects of anti-tuberculosis drugs in the non-nutritional risk group and the nutritional risk group were comparatively analyzed. Results Among the 168 patients, 64 were assessed as having good nutritional status before treatment, 59 had the risk of malnutrition and 45 were malnourished according to the MNA score. Univariate analysis and linear regression analysis showed that age, underlying diseases, and clinical symptoms were factors affecting the MNA score before treatment (t=3.173, 3.718, 2.018, P all<0.05); whereas gender and education level were not factors affecting MNA score before treatment (t=0.065, 0.059, P all>0.05). According to the MNA score before treatment, the patients were dividedinto a non-nutritional risk group (MNA score > 23.5) and a nutritional risk group (MNA score ≤23.5). The negative conversion rate of sputum bacteria, effective rate of focal absorption in the non-nutritional risk group were 92.19% (59/64)and90.63% (58/64) , respectively, which were significantly higher than corresponding 79.85% (82/104)and76.92% (80/104) in the nutritional risk group. The drug resistance rate, adverse reaction rate, and average treatment cost of the no nutritional risk group and nutritional risk group were 7.81% (5/64) and 21.15% (12/104), 15.63% (10/64) and 31.73% (33/104), (0.62±0.13) million yuan and (0.89±0.26) million yuan, respectively, with significant differences (χ2=5.228, 5.071, 7.685, 5.396, 7.728, P all<0.05). Conclusions Patients with pulmonary tuberculosis exhibit poor nutritional status before treatment. The patients’nutritional status is easily affected by age, underlying diseases, and clinical symptoms, thereby affecting the effect of anti-tuberculosis treatment. Therefore, early nutritional intervention for tuberculosis patients should be recommended in order to prevent malnutrition and enhance the effectiveness of anti-tuberculosis treatment.

Analysis of drug susceptibility test results of 697 cases of drug-resistant Mycobacterium tuberculosis in Hainan Province / 中国热带医学

@#Abstract: Objective To investigate the type and distribution of drug resistance of Mycobacterium tuberculosis (MTB) in Hainan tuberculosis hospital from 2019 to 2021, and to provide reference for the development of drug resistant tuberculosis prevention and control strategy. Methods From 2019 to 2021, a total of 1 687 strains of sputum were isolated and cultured and identified as MTB. Drug sensitivity testing was performed on eight anti-tuberculosis drugs: isoniazid (INH), rifampicin (RFP, R), ethambutol (EMB), streptomycin (SM), kanamycin (KM), capreomycin (CPM), ofloxacin (OFX), and propylthioisoniacamide (PTO). The drug resistance analysis was conducted. Results Among the 1 687 MTB strains, the overall drug resistance rate was 41.32% (697), with a single drug resistance rate of 11.62% (196), a multi-drug resistance rate of 4.10% (69), a extensive drug resistance rate of 23.71% (400), a pan-drug resistance rate of 1.90% (32), and a rifampicin resistance rate of 28.10% (474), and the main drug resistance types were extensive drug resistance and rifampicin resistance. The order of resistance to the eight drugs was OFX (64) > SM (62) > INH (48) > RFP (19) > CPM (2) > KM (1) > EMB (0) and PTO (0). The rate of resistance to INH and RFP of first-line drugs in newly treated patients was lower than that in retreated patients (χ2=0.110, 0.765; P>0.05); the rate of resistance to second-line drugs OFX, CPM and KM in initially treated patients was lower than that in retreated patients (χ2=1.037, 1.212, 1.653; P>0.05). The total drug resistance rate in 2019 was 51.16%, which was higher than that in 2020 (35.08%) and 2021 (38.89%). The difference between groups was significant (χ2=29.25,16.60; P=0.000), but there was no significant difference in overall drug resistance rate between 2020 and 2021 (χ2=1.823, P=0.177). Among the occupational types of tuberculosis patients, farmers were the main ones, accounting for 56.25% (949). The patients with drug-resistant tuberculosis were mainly distributed in Haikou City (165) > Wanning City (72) > Chengmai County(64) > Wenchang City (51) = Dongfang City (51) > Danzhou City (48), and patients in these six areas accounting for 64.71%(451/697). Conclusions The drug resistance rate of tuberculosis in Hainan Province is relatively high, with OFX and SM resistance being the main types of drug resistance. The extensive drug resistance rate is higher than the national average level. Therefore, surveillance and treatment should be strengthened and optimized to reduce the prevalence of drug-resistant tuberculosis.

A case report of stage Ⅲ silicosis complicated by pulmonary tuberculosis and secondary pneumothorax treated with minimally invasive thoracoscopic surgery / 中国职业医学

Objective To analyze the feasibility of using minimally invasive thoracoscopic surgery to treat stage Ⅲ silicosis complicated by pulmonary tuberculosis and secondary pneumothorax. Methods This study retrospectively analyzed the clinical data of a patient with stage Ⅲ silicosis complicated by pulmonary tuberculosis and secondary pneumothorax. Results The patient had stage Ⅲ silicosis complicated with active pulmonary tuberculosis for 1.5 years. In March 2021, a left-sided pneumothorax occurred and was conservatively treated with closed chest drainage. In April 2022, the patient was admitted with sudden frequent coughing and left-sided chest discomfort. Based on occupational history, dust exposure history, high-kilovolt anterior-posterior chest radiography, chest computed tomography, and sputum smear results, the diagnosis was "stage Ⅲ silicosis; active tuberculosis (positive for acid-fast bacilli in sputum smear); left-sided pleural effusion, pulmonary bulla rupture; secondary pneumothorax (recurrent tension type in left, encapsulated in right); left pleural adhesion". On the second day of admission, left-sided closed chest drainage was performed with poor outcome. On the fifth day of admission, minimally invasive thoracoscopic treatment was performed, including left lung volume reduction, pleural adhesion cauterization, and pleural fixation. Postoperative anti-inflammation, anti-tuberculosis, and symptomatic supportive treatments were administered. Due to the patient's severe underlying disease, wound healing was slow postoperatively, but no serious complications occurred. The pneumothorax completely absorbed and recovered in 17.0 days. Conclusion Minimally invasive thoracoscopic surgery is an effective treatment for silicosis complicated with pulmonary tuberculosis and secondary pneumothorax, and it is worth promoting.

Integrated Chinese and Western Medicine for Tuberculosis and Severe Malnutrition with Coronavirus Disease 2019（Critical Type）： A Case Report / 中医杂志

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.

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.

Clinical characteristics of liver injury caused by anti-tuberculosis drugs in newly treated pulmonary tuberculosis patients co-infected with hepatitis B virus / 公共卫生与预防医学

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.
