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

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

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

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

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

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.

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

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

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

The relationship between compliance and perceived social support in young patients with newly treated pulmonary tuberculosis based on the Southern Xinjiang Model: the mediating role of medication self-efficacy / 中国实用护理杂志

Objective:To explore the mediating effect of medication self-efficacy between perceived social support and compliance behavior in young patients with newly treated pulmonary tuberculosis under the Southern Xinjiang Model.Methods:A cross-sectional survey was conducted in Kashgar Tuberculosis Prevention and Control Institute Hospital and Tuberculosis Specialist Hospital of Hetian from January 2022 to April 2023. A total of 302 young patients with initial treatment of pulmonary tuberculosis in were selected as the research objects by convenience sampling method. The General Information Questionnaire, the Tuberculosis Compliance Behavior Rating Scale, Perceived Social Support Scale and Self-efficacy for Appropriate Medication Use scale were used to investigate, and the correlation analysis and mediating effect analysis were carried out.Results:The total scores of compliance behavior, self-efficacy and perceived social support were (119.09 ± 13.49), (23.48 ± 6.25) and (55.67 ± 11.33) respectively. All dimensions of medication self-efficacy and perceived social support were positively correlated with compliance behavior ( r values were 0.555 - 0.943, all P<0.01), and medication self-efficacy was positively correlated with perceived social support ( r = 0.981, P<0.01). Medication self-efficacy played a partial mediating effect between perceived social support and compliance behavior, accounting for 74.46% of the total effect. Conclusions:The medication self-efficacy of young patients with newly treated pulmonary tuberculosis is the mediating variable between perceived social support and compliance behavior. Medical staff should focus on and carefully evaluate the medication self-efficacy and perceived social support of patients, so as to give supportive intervention in time, so as to change or even reverse the non-compliance behavior and improve the compliance level of patients.

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.

Aspergilosis pulmonar crónica en asociación con tuberculosis activa: reporte de un caso

La aspergilosis es una infección fúngica causada por el microorganismo Aspergillus spp. Las manifestaciones clínicas dependen del estado inmunológico del paciente y de las alteraciones estructurales del parénquima pulmonar. Pese a su baja incidencia, siempre se debe considerar como diagnóstico diferencial en el contexto de pacientes con enfermedades pulmonares de base. Se presenta un caso de hombre de 66 años, agricultor, con antecedente de tuberculosis pulmonar y enfermedad pulmonar obstructiva crónica, quien consultó por cuadro de 5 meses de disnea progresiva, fiebre, tos, hemoptisis y pérdida de peso. Los hallazgos imagenológicos fueron sugestivos de tuberculosis pulmonar asociado a aspergiloma, lo que fue confirmado por tinción de hidróxido de potasio (KOH) y cultivo de hongos positivo para Aspergillus fumigatus. El Gene Xpert fue positivo para Mycobacterium tuberculosis demostrando coinfección activa.

Aspergillosis is a fungal infection caused by the microorganism Aspergillus spp. Clinical manifestations depend on the patient's immune status and structural alterations of the lung parenchyma. Despite its low incidence, it should always be considered as a differential diagnosis in the context of patients with underlying lung diseases. We present the case of a 66-year-old male farmer, with a history of pulmonary tuberculosis and chronic obstructive pulmonary disease, who presented with progressive dyspnea months, fever, cough, hemoptysis and weight loss for 5 months. Imaging findings were suggestive of aspergiloma- associated pulmonary tuberculosis, which was confirmed by potassium hydroxide (KOH) staining and positive fungal culture for Aspergillus fumigatus. Gene Xpert was positive for Mycobacterium tuberculosis showing active co-infection.

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

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

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

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

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.

Se realizaron entrevistas individuales y se utilizó la técnica de análisis de contenido. Resultados: entre los participantes, 45/77,6% eran mujeres y 33/56,9% tenían entre 25 y 40 años. Se organizaron dos categorías temáticas, demostrando las percepciones sobre las posibilidades de acceso a los programas gubernamentales por parte de las personas con tuberculosis pulmonar en situación de vulnerabilidad y los obstáculos inherentes a este contexto. Consideraciones finales: es necesario avanzar en mejorar el acceso de los pacientes a los programas sociales.

Treatment outcome and influencing factors of isoniazid mono-resistant pulmonary tuberculosis / 中华传染病杂志

Objective:To analyze the outcomes of isoniazid (INH) mono-resistant pulmonary tuberculosis, and risk factors associated with adverse treatment outcomes of INH mono-resistant pulmonary tuberculosis.Methods:A total of 114 cases of INH mono-resistant pulmonary tuberculosis in Xi′an Chest Hospital from January 1, 2018 to December 31, 2020 were retrospectively recruited for analysis. The general information, clinical symptoms, and laboratory test results of patients were collected. With treatment success and adverse treatment outcomes as dependent variables, binary logistic regression analysis was used to analyze the risk factors for the adverse treatment outcome of INH mono-resistant pulmonary tuberculosis.Results:Among 114 patients with INH mono-resistant tuberculosis, 46 cases (40.4%) were cured and 41 cases (36.0%) completed treatment with the success rate of 76.3%(87/114), while 11 cases (9.6%) failed treatment, 13 cases (11.4%) lost to follow up, three cases (2.6%) died.The binary logistic regression analysis showed that male (odds ratio ( OR)=7.22, 95% confidence interval ( CI) 1.47 to 35.43)), no fever at onset ( OR=12.97, 95% CI 2.74 to 61.55), not containing amikacin in the regimen ( OR=5.28, 95% CI 1.20 to 23.31), sputum bacteria load >1+ ( OR=5.87, 95% CI 1.76 to 19.60) were the risk factors for adverse treatment outcomes of INH mono-resistant tuberculosis. Conclusions:The treatment success rate of INH mono-resistant pulmonary tuberculosis patients is high. The risk factors for adverse treatment outcome are male, no fever at the onset, not containing amikacin in the regimen, and sputum bacteria load >1+ .

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

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

Retrospective analysis of multiple factors combination for early identification of pulmonary tuberculosis complicated with pulmonary embolism / 中华传染病杂志

Objective:To analyze the independent diagnostic indicators and their diagnostic values for pulmonary tuberculosis complicated with pulmonary embolism.Methods:A total of 34 cases of pulmonary tuberculosis complicated with pulmonary embolism treated in Huzhou Central Hospital from March 2014 to September 2021 were enrolled. And 136 patients with simple pulmonary tuberculosis who were hospitalized during the same period were collected with a ratio of 1∶4 according to the principle of age and gender matching. The general conditions, clinical symptoms, comorbidities and laboratory indicators of the patients were retrospectively analyzed. The univariate analysis was performed using independent samples t test, Mann-Whitney U test and chi-square test. Binary logistic regression was used to analyze the related diagnostic factors for pulmonary embolism in pulmonary tuberculosis patients, and the combined factors were constructed by transforming the model equation, and the receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value and evaluate its diagnostic value. Results:The univariate analysis showed that patients with pulmonary tuberculosis complicated with pulmonary embolism had higher ratio of chest tightness (67.6%(23/34) vs 22.1%(30/136)), syncope (23.5%(8/34) vs 0.7%(1/136)), fever (55.9%(19/34) vs 36.0%(49/136)), hemostatic drug use (100.0%(34/34) vs 13.2%(18/136)), history of venous thrombosis (8.8%(3/34) vs 0.7%(1/136)), atrial fibrillation (11.8%(4/34) vs 2.2%(3/136)) and D-dimer levels (4.090 0(1.035 0, 10.790 0) mg/L vs 0.850 0(0.432 5, 2.145 0) mg/L) than those of simple pulmonary tuberculosis patients, and the differences were all statistically significant ( χ2=26.35, 28.19, 4.47, 96.44, 7.75, 6.30 and Z=-4.65, respectively; all P<0.050). The arterial partial pressure of oxygen (PaO 2)(61.90(52.95, 73.00) mmHg vs 82.00 (75.00, 87.00) mmHg, 1 mmHg=0.133 kPa) and albumin ((28.83±4.98) g/L vs (32.76±5.65) g/L) of patients with pulmonary tuberculosis complicated with pulmonary embolism were lower than those of simple pulmonary tuberculosis patients, and the differences were both statistically significant ( Z=-5.21 and t=3.71, respectively, both P<0.001). Binary regression analysis showed that chest tightness (odds ratio ( OR)=3.494, 95%confidence interval ( CI) 1.208 to 10.100, P=0.021), D-dimer ( OR=1.285, 95% CI 1.079 to 1.530, P=0.005) and PaO 2( OR=0.931, 95% CI 0.895 to 0.970, P=0.001) were the independent diagnostic indicators for pulmonary embolism in pulmonary tuberculosis patients. The areas under the ROC curve of chest tightness, D-dimer, PaO 2, and the combination of the three indicators (the combination factor) were 0.728, 0.758, 0.834, and 0.890, respectively. The optimal cut-off value of the combination factor was -3.1, with the sensitivity of 0.824 and the specificity of 0.824. Conclusions:Chest tightness, increased D-dimer and decreased PaO 2 are independent diagnostic indicators for pulmonary embolism in pulmonary tuberculosis patients. It is recommended to perform pulmonary artery computed tomography angiography promptly when the combination factor is higher than -3.1 to determine whether the patient is complicated by pulmonary embolism.

Evolution of CT characteristics of reversed halo sign in pulmonary tuberculosis / 中华放射学杂志

Objective:To explore the evolution of CT characteristics of the "reversed halo sign" of pulmonary tuberculosis, and to further improve the recognition of its CT signs.Methods:Clinical and CT data of 12 patients with pulmonary tuberculosis who were clinically and pathologically confirmed and accompanied with CT manifestation of "reversed halo sign" in First Affiliated Hospital of Henan University of Science and Technology from August 2013 to April 2020 were analyzed retrospectively. Pathological and imaging contrastl analysis was performed on 1 patient undergoing surgical treatment.Results:Among 12 cases with "reversed halo sign", there were 2 cases with single lesion in unilateral lung, 2 cases with multiple lesions in unilateral lung, and 8 cases with multiple lesions in bilateral lungs. Three cases showed only "reversed halo sign", 9 cases showed both halo-like sign and uniform fireworks sign. "Tree-in-bud "sign was found in all 12 patients in the outer ring of the "reversed halo sign". Eight patients received three or more CT examinations, and six of them showed reduction of density and volume of the "reversed halo sign" after standardized anti-tuberculosis treatment. Under the natural course of the disease in two cases, the overall enlargement of the lesion was observed in 1 case, and the overall density of the lesion was reduced and the outer ring wall of the "reversed halo sign" was thinned in 1 case. The pathology of one case after surgical lobectomy showed granulomatous inflammatory nodules of varying sizes containing Langerhans nodule giant cells in the lung parenchyma. The typical caseous necrotic granulomatous nodules were rare here. The "reversed halo sign" showed dense Langerhans nodules in the outer ring, sparse central areas with fibrous hyperplasia and alveolar wall thickening.Conclusions:The outer ring of "reversed halo sign" of pulmonary tuberculosis shows as "tree-in-bud" sign, and its center shows as the fine reticulation pattern. After effective anti-tuberculosis treatment, both the overall density of "reversed halo sign" and the lesion size reduced. Finally, the lesions mostly present as as fine grid shadows for a long time.

The value of myeloid-derived suppressor cell and T lymphocyte subsets in the diagnosis and treatment of active pulmonary tuberculosis / 中国医师进修杂志

Objective:To investigate the levels and correlation between myeloid-derived suppressor cell (MDSC) and T lymphocyte subsets in peripheral blood of patients with active pulmonary tuberculosis.Methods:A total of 38 patients with active pulmonary tuberculosis in Nanjing Second Hospital from February 2019 to June 2020 were selected as the tuberculosis group, and 23 healthy outpatient physical examination patients were selected as the healthy control group during the same period. The levels of MDSC, clinically related indicators, inflammatory cytokines and lymphocyte subsets were compared between each group, and the correlation between MDSC and lymphocyte subsets was analyzed. Meanwhile, the levels of MDSC and lymphocyte subsets before and after treatment were compared.Results:The MDSC and CRP in tuberculosis group were higher than those in healthy group: (16.41 ± 2.13)% vs. (1.82 ± 0.54)%, (25.42 ± 10.56) mg/L vs. (5.82 ± 1.39) mg/L ( P<0.05). Serum inflammatory cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-1β, IL-10 and interferon (IFN)-γ in tuberculosis group were significantly higher than those in healthy control group ( P<0.05). T lymphocyte subsets CD 3+ T cell, CD 4+ T cell, CD 8+ T cell and CD 16/56+ nature killer (NK) cell in tuberculosis group were significantly lower than those in healthy control group ( P<0.05), while the number of CD 19+ B cell was not statistically significant ( P>0.05). Correlation analysis showed that MDSC was negatively correlated with T lymphocyte subsets CD 3+ T cell ( r = -0.73, P<0.001), CD 4+ T cell ( r = -0.68, P<0.001) and CD 8+ T cell ( r = -0.53, P = 0.001), but had no significant correlation with CD 16/56+ NK cell ( r = -0.10, P = 0.561). CD 3+ T cell, CD 4+ T cell, CD 8+ T cell and CD 16/56+ NK cell were significantly different in peripheral blood MDSC before and after treatment ( P<0.05). Conclusions:MDSC, CD 3+ T cell, CD 4+ T cell, CD 8+ T cell and CD 16/56+ NK cell have a guiding role in the diagnosis and evaluation of the curative effect of active pulmonary tuberculosis, with high value in clinical application.

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

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

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

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

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

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

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

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

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