Background Regardless of the advancement in medical technologies, the diagnosis of tuberculosis (TB) in children has remained a challenge. Childhood TB is rampant and an important cause of morbidity and mortality. The objective of this study was to determine the trend of TB and treatment outcomes in children aged ≤14 years registered for TB treatment under DOTS course in three districts of Sindh, Pakistan. Methods For this retrospective study, records of TB children (≤14 years) registered for the treatment of TB from January 2011 to December 2015 in three districts of Pakistan, were collected. Demographic data, baseline weight, clinical manifestations, radiography, histopathology results and treatment outcomes were collected from TB unit registers. Results A total of 2,167 children were treated for TB during the study period. Of these, 1,199 (55.3%) were females and 1,242 (57.3%) were from urban areas. Over three-quarter of patients (76.9%) had pulmonary TB with 13.3% of sputum smear positive cases. The overall treatment success rate was 92.4%. In multivariate analysis, rural residents (OR: 2.146, p < 0.001), sputum smear positive cases (OR: 3.409, p < 0.001) and re-treated patients (OR: 5.919, p < 0.001), were significantly associated with unsuccessful treatment outcomes. However, age group ≤2 years, male and those who were underweight were found to have the highest risk of pulmonary tuberculosis (OR: 1.953, p < 0.001; OR: 1.262, p = 0.028; OR: 1.342, p = 0.008), respectively. Conclusion Patients at risk of treatment failure must be given particular attention. Moreover, strategies are needed to further improve the diagnosis and treatment of TB among children and improve the recording system.

Abstract Background: Tuberculosis remains a major global health problem and ranks along with the human immunodeficiency virus (HIV) as a leading cause of mortality worldwide. The aim of this study was to investigate the treatment outcome of tuberculosis, and factors associated with treatment outcome of tuberculosis in TB patients enrolled in Arsi-Robe Hospital, Oromia regional state, South eastern Ethiopia between January 2013 to December 2017. Methods: An Institutional-based retrospective study was conducted in Arsi-Robe Hospital from 2013 to 2017 in study patients who had all forms of TB in DOTS clinic. The predictors of treatment outcomes were analyzed through bivariate and multivariable logistic regression analysis and a P-value < 0.05 were considered statistically significant. Results: Out of the 257 registered TB patients, most of them were males (57.9%), from rural areas (62.6%) and in age of 15-24 category (39.3%). PTB-, PTB+ and EPTB were recorded in 48.2%, 32% and 19.8% of the patients, respectively. Among all cases, 8.6% had TB-HIV co-infection. Among all TB cases, 84.0% had successful treatment outcome. TB patients from urban areas (AOR: 3.34, 95% CI: 1.33­8.38, P = 0.01), with failure treatment (AOR: 6.66, 95% CI = 1.12- 39.57; P = 0.037) and HIV positive (AOR: 4.92, 95% CI = 1.38-17.51; P = 0.014) had higher odd of unsuccessful treatment outcome of tuberculosis. However, TB patients with PTB+ (AOR: 0.1470, 95% CI = 0.031-0.687; P = 0.015) and EPTB (AOR: 0.194, 95% CI = 0.054-0.688; P = 0.011) had significantly lesser odd of unsuccessful treatment outcome. Conclusions: Being urban resident, treatment failure and HIV positive considerably challenge the treatment outcome of tuberculosis, but being PTB+ and EPTB were associated with higher treatment success rate of TB. Continuous follow-up of patients with unsuccessful treatment outcome of tuberculosis with strengthened implementation of the DOTs strategies are suggested. Trial Registered: retrospectively registered

Abstract Background Extra-pulmonary tuberculosis (EPTB) represents about 14% of all cases of tuberculosis (TB) in Malaysia. The aims of the study include evaluation of socio-demographic factors, clinical manifestations, co-morbidities among patients with Tuberculous Lymphadenitis and their treatment outcomes.Methods The retrospective study was conducted from 2006 to 2008. Data on socio-demographic along with histopathological results were collected. Signs and symptoms were also recorded from TB registers, treatment cards and TB medical personal files using standard data collection tool. Among multiple variables significant factors identified by univariate analysis, were included in multivariate logistic regression to estimate the odds ratios (ORs) with the 95% confidence intervals (CIs). The statistically significant p value was considered as < 0.05.Results There were 348 (57%) males and on the other hand 262 (43%) females which shows almost equal incidence rate of Lymphadenitis in both genders. Mean age was found as 34.3 ± 14.6 years were majorly reported with positive diagnosis. 196 (32.1%) Malay was found with Tuberculous lymphadenitis followed by Chinese population of 148 (24.3%). Geographically from 386 (63.3%) urban population were found positive for lymphadenitis and over 224 (36.7%) of rural region. treatment outcome was observed 444 (72.8%) with successful treatment. WHO states the types of treatment failures and accordingly 85 (13.9%) patients were continued with the therapy that can be due to non-compliance or relapse of Tb. Among unsuccessful outcomes 194 patients of age group 26 -35 years, 65 (33.5%) were reported and 38 (29.7%) patients out of 128 between 16 – 25 years. Blood results showed erythrocyte sedimentation rate greater than 10 in 280 (45.9%) patients. Therefore, among 280 there were 115 (41.1%) patients found to have unsuccessful treatment showing strong association with p-value of <0.001.Conclusion Finding signifies that effect of weight loss on poor treatment outcomes` and active screening measures for patients with comorbidities are therefore recommended in patients with Tb lymphadenitis along with improvements in the diagnosis and early management of co-morbidities complications. As young age group were found to have poor or unsuccessful treatment outcomes and required aggressive strategy together with educating patients can further increase the treatment success rate.

Abstract Background Tuberculosis (TB) disease is the leading cause of death from a single infectious agent globally. Medication adherence will be more valuable if it improves clinical/treatment outcomes of the patient because treatment outcomes are major indicators for evaluating TB therapy. Objective To examine a fifteen-year record of tuberculosis treatment outcomes in Jos North and Mangu Local Government Areas of Plateau State. Methods The retrospective registry based study was done in five TB treatment centers which account for more than half of data for tuberculosis patients in Plateau State, North-Central Nigeria. Data were collected from 10,156 TB patient’s health records from 2001 to 2015. Treatment outcomes were classified as successful (cured, treatment completed) or unsuccessful (non-adherent, treatment failure or death). Analysis was done descriptively and factors associated with treatment outcomes were determined using multiple logistic regression with the aid of Stata version 11. Results Males were 58.1% of the population (10,156). Mean age ±SD was 35.5±15.5 years. The overall treatment success rate was 67.4%; non-adherence/defaulting rate was 18.5%, with majority of patients defaulting at the end of intensive phase of treatment; sputum conversion rate was 72.8% and mortality rate was 7.5%. A decrease in successful treatment outcomes from 83.8% to 64.4%, with a corresponding increase in unsuccessful treatment outcomes was observed. After adjusting for sex, and TB category, being HIV positive was 2.8 times (95% CI: 1.11-6.83, p =0.028) more likely to be associated with treatment success than having an unknown status. TALF/RAD, relapse and MDR-TB were less likely associated with treatment success than newly diagnosed TB patients Conclusion Underlying reasons for medication non-adherence and treatment failure identified should be resolved by the patient, treatment supporter and health system through adherence counseling, increased education on voluntary counseling and testing of HIV among TB patients.

Background Remaining underweight during Tuberculosis (TB) treatment is associated with a higher risk of unsuccessful TB treatment outcomes and relapse. Previous studies conducted in Ethiopia found that bodyweight not adjusted for height at the start of treatment is associated with poor treatment outcomes. However, the association of body mass index (BMI) and weight change during treatment with treatment outcomes has not been studied. We aimed to investigate the association of BMI at the time of diagnosis and after two months of treatment and TB treatment outcomes. Methods Using an ambi-directional cohort study design (retrospective and prospective), a total of 456 participants were enrolled among 30 randomly selected public health centers residing within six sub-cities of Addis Ababa, Ethiopia. Data were collected using medical chart abstraction and face to face interviews. We compared TB treatment outcomes in persons with a body mass index (BMI) <18.5kg/m2 (underweight) versus persons with BMI ≥18.5kg/m2 (normal or overweight) at treatment initiation and after two months of treatment. Treatment was classified as successful in persons who were free of symptoms and had a negative sputum smear for acid-fast bacilli at the end of the 6-month treatment course. We analysed outcomes using univariable and multivariable logistic regression with 95% CI and p value< 0.05. Results Of enrolled study participants, 184 (40.4%) were underweight and 272 (59.6%) were normal or overweight. Body mass index (BMI ≥18.5kg/m2) at the start and second month of treatment were independent predictors for successful treatment outcome (AOR = 2.15; 95% CI: 1.05, 4.39) and (AOR = 3.55; 95% CI: 1.29, 9.73), respectively. The probability of treatment success among patients with BMI≥18.5kg/m2 at the start and second month of treatment was 92.9% and 97.1%, respectively versus 86.5% and 91.7% in patients with BMI<18.5kg/m2. Bodyweight not adjusted for height and change in the bodyweight after the second and sixth months of treatment were not significantly associated with treatment success. Conclusion In persons treated for TB disease, being underweight at baseline and after two months of treatment was a predictor for unsuccessful treatment outcomes. Nutritional assessment, counselling, and management are important components of TB treatment programs with the potential to improve treatment outcomes.

Abstract Background: Tuberculosis (TB) is more severe in refugee populations. Analyzing the key indicators of TB program performance is important to improve the effectiveness of TB control in the refugee camps. This study aimed to analyze trends in TB case notification, treatment outcomes and factors associated with unsuccessful TB treatment in Dadaab and Kakuma refugee camps in Kenya. Methods: In this descriptive retrospective study, demographic and clinical data all TB cases registered in the refugee camps from January 2014 to December 2017 were extracted. Multiple logistic regression analysis was used to estimate odds ratios and 95% confidence intervals for variables associated with unsuccessful TB treatment.Results. A total of 2055 TB cases of whom 56.8% men and 57.7% age 15-44 years were registered. Number of notified cases decreased from 532 in 2014 to 473 in 2016 (11.1% decrease) then increased to 554 in 2017(16.9% increase in one year). From 2014 to 2017 there was consistent increase in percentage of EPTB (16.2% to 21.1%), and in contribution of children (<15 years) to total TB cases (20.3% to 25.8%) and to EPTB (36.1% to 44.4%). Proportion of bacteriologically confirmed new and relapse pulmonary cases increased from 49.5% to 60.9%. Treatment success rate remained higher at 92.6% to 94.4%. On average 41.7% were cured, 2.3% lost to follow-up (LTFU) (increasing from 1.3% to 3.2%), 2.2% died (decreasing from 2.4% to 1.6%), 1.6% not evaluated (decreasing from 3.2% to 1.3%), and 0.5% treatment failed. Unsuccessful treatment outcome was significantly associated with pretreatment weight < 40 Kg, being male, smear positive PTB, HIV infection, and age >15 years (increased with age).Conclusions: Number of notified TB cases has decreased from 2014 to 2016, but increased in 2017. There was continuous increase in percentage of EPTB and childhood TB. Proportion of bacteriologically confirmed new and relapse pulmonary cases has increased overtime. Treatment success remained higher above global target (90%) which should be maintained. Special socioeconomic support and follow-up is required for TB patients who are at higher risk of unsuccessful treatment.

Background: The shorter regimen was widely accepted and advocated for MDR-TB treatment compared tothe conventional longer regimen. Evaluating the performance of both regimens in a programmatic setting will help in tailoring the treatment regimen of MDR-TB. Objectives: 1. To estimate the duration of sputum smear conversion in the shorter MDR-TB regimen. 2. To compare the treatment outcomes of the shorter MDR-TB regimen with that of the longer conventional MDR regimen in a programmatic set up in India. 3. To estimate the adverse drug reactions in the shorter MDR-TB regimen. Methods: A retrospective cross-sectional study was conducted on 320 patients enrolled under programmatic management of drug resistant tuberculosis (PMDT) from April 2017 to May 2019 at a nodal DRTB center and a tertiary care hospital in India. Demographic and clinical characteristics of those who received a shorter MDR-TB regimen were recorded. Treatment outcomes of both regimens were recorded. Treatment success is defined as ‘disease cured and treatment completed’, whereas treatment failure was considered when the treatment was either terminated or changed due to lack of bacteriological conversion at the end of an extended intensive phase or culture reversion in the continuation phase. Results: The treatment success observed in the shorter MDR-TB regimen was 61.25%, which was significantly higher than the conventional longer regimen (p=0.0007). Treatment failures were higher with a shorter MDR-TB regimen (p=0.0001). Conclusion: Treatment success with the shorter MDR-TB regimen though higher than the conventional regimen, is still way behind the target treatment success rate. Improving treatment adherence remains pivotal for achieving end TB targets.

Abstract Background This study aims to evaluate the treatment outcomes and factors associated with unsuccessful treatment outcomes among multidrug-resistant TB (MDR-TB) patients. Method This was a retrospective observational study conducted at the Bahawal Victoria Hospital, Bahawalpur, Pakistan. The sociodemographic, clinical and treatment-related data of MDR-TB patients registered at the study site between June 2014 and December 2016 were retrospectively collected. Patients’ treatment outcomes were categorized on the basis of WHO-recommended criteria. Multivariate binary logistic regression analysis was used to find the independent factors associated with unsuccessful treatment outcomes. Results Out of 179 MDR-TB patients, 106 (59.2%) completed their treatment successfully. The remaining 73 patients (40.8%) had unsuccessful treatment outcomes, among whom 45 (25.1%) died, while 18 (10.1%) were lost to follow-up. Factors associated with unsuccessful treatment outcomes included age ≥40 y (AOR 4.310; p = 0.006), unsuccessful interim treatment outcomes (AOR 5.810; p = 0.032), occurrence of adverse events (AOR 0.290; p = 0.029) and ofloxacin resistance (AOR 2.952; p = 0.042). Conclusion The treatment success rate among the selected cohort of MDR-TB patients was less than the target of ≥75% set by the WHO in the End TB Strategy. The lower treatment success rate at the study site requires urgent attention from clinicians and program managers.

Introduction. Tuberculosis poses a great threat to public health around the globe and affects persons mostly in their productive age, notwithstanding; everyone is susceptible to tuberculosis (TB) infection. To assess the effectiveness and performance of the tuberculosis control program activities, the percentage of cases with treatment success outcome is key. To control tuberculosis, interrupting transmission through effective treatment cannot be overemphasized. The study was conducted to determine factors associated with TB treatment outcome, in the Atwima Nwabiagya District from 2007–2017. Method. A Retrospective review of routine/standard TB registers was carried out in five directly observed therapy short-course (DOTS) centres at the Atwima Nwabiagya District from January 2007 to December 2017. Demographic characteristics, clinical characteristics, and treatment outcomes were assessed. Bivariate and multivariate logistic regression was conducted to determine the predictors of successful treatment outcome. Results. Of the 891 TB client’s data that was assessed in the district, the treatment success rate was 68.46%. Patients, aged ≤ 20 years (adjusted odds ratio aOR = 4.74 , 95 % CI = 1.75 − 12.83 ) and 51-60 years ( aOR = 1.94 , 95 % CI = 1.12 − 3.39 ), having a pretreatment weight of 35-45 kg ( aOR = 2.54 , 95 % CI = 1.32 − 4.87 ), 46-55 kg ( aOR = 2.75 , 95 % CI = 1.44 − 5.27 ) and 56-65 kg ( aOR = 3.04 , 95 % CI = 1.50 − 6.14 ) were associated with treatment success. However, retreatment patients ( aOR = 0.31 , 95 % CI = 0.11 − 0.84 ) resulted in unsuccessful treatment outcome. Conclusion. Successful treatment outcome among TB patients was about 20.00% and 30.00% lower compared to the national average treatment success rate and WHO target, respectively. Active monitoring, motivation, and counselling of retreatment patients and patients with advanced age are key to treatment success.

Abstract Background Tuberculosis (TB) is an infectious disease with a major global health problem; being the tenth leading cause of death worldwide, and the leading cause of death from a single infectious agent. Nigeria is among the countries with high burden of tuberculosis and the highest global mortality rate. Medication adherence has been shown to have profound effect on other treatment outcomes. Objective To examine a fifteen-year cohort of tuberculosis treatment outcomes in Jos North and Mangu Local Government Areas of Plateau State. Methods The study was done in five treatment centers which account for more than half of data for tuberculosis patients in Plateau State, North-Central Nigeria. The retrospective study was done from 2001 to 2015, where TB patient records who had completed treatment were evaluated. Treatment outcomes were classified as successful (cured, treatment completed) or unsuccessful (non-adherent, treatment failure or death) and analyzed using binomial logistic regression. Results Males composed 58.1% of the population (10,156). Mean age ±SD was 35.5±15.5 years. The overall treatment success rate was 67.4%; non-adherence/defaulting rate was 18.5%, with majority of patients defaulting at the end of intensive phase of treatment; sputum conversion rate was 72.8% and mortality rate was 7.5%. A decrease in successful treatment outcomes from 83.8% to 64.4%, with a corresponding increase in unsuccessful treatment outcomes was observed. The Predictors of medication non-adherence were patients with unknown HIV status (OR 4.29, 95% CI: 3.74-4.91, p < 0.001); being male (OR 1.15, CI: 1.37-1.66, p = 0.008) and having a history of non-adherence (OR 2.27, CI: 1.34-3.87, p = 0.002) and treatment failure (OR 2.83, CI: 0.98 – 8.19, p = 0.05). Conclusion Underlying reasons for medication non-adherence and treatment failure identified should be resolved by the patient, treatment supporter and health worker. Increased awareness and education on voluntary counseling and testing of HIV among TB patients is advocated, particularly among the male population.
