Treatment outcome of human immunodeficiency virus and tuberculosis co-infected patients in public hospitals of eastern and southern zone of Tigray region, Ethiopia

Age-specific relationship between HIV and TB treatment outcomes in the West Region of Cameroon: a cross-sectional study

BACKGROUND

Co-infection with Mycobacterium tuberculosis (M. tuberculosis) and Human Immunodeficiency Virus (HIV) poses significant global public health challenges, with varying impacts across age cohorts. Evaluating tuberculosis (TB) treatment outcomes, especially among HIV patients across different age groups, is crucial for effective TB management. This study assessed the age-specific relationship between HIV status and TB treatment outcomes among TB patients in Cameroon.

METHODS

This cross-sectional study included 2,455 TB patients receiving treatments in the West Region of Cameroon between January 2015 and December 2019. Data were extracted from National Tuberculosis Program Registers. The association of TB treatment outcomes with HIV and age was assessed using multivariate logistic regression.

RESULTS

TB-HIV co-infection was significantly associated with lower TB treatment success. For HIV patients on antiretroviral therapy (ART), the odds ratio (OR) was 0.463 (95% confidence interval [CI]: 0.367-0.583, Bonferroni-adjusted P < 0.001). For HIV patients not on ART, the OR was 0.077 (95% CI: 0.030-0.200, Bonferroni-adjusted P < 0.001). A significant trend (P < 0.001) further indicated a consistent association between TB-HIV co-infection and treatment status. Older age was significantly associated with slightly lower treatment success (OR: 0.976; 95% CI: 0.969-0.983, Bonferroni-adjusted P < 0.001). TB-HIV co-infection remained significantly associated with lower TB treatment success after age categorization (OR; 95% CI, Bonferroni-adjusted P = 0.498; 0.394-0.631, < 0.001 for HIV patients on ART and 0.081; 0.032-0.210, < 0.001 for those without ART). The interaction between age and HIV was significant (P < 0.001). Age stratification revealed a significantly lower treatment success among HIV patients aged 25 and above, especially those not taking ART: OR (95% CI, Bonferroni-adjusted P) = 0.101 (0.032-0.312, < 0.001) and 0.038 (0.004-0.322, 0.025) for 25-44 and ≥ 45 years, respectively.

CONCLUSION

In this study, HIV status and older age were jointly associated with lower TB treatment success. Notably, treatment success was lower among HIV-positive patients aged 25 and above, especially those not on ART. Effective patient management, routine follow-up, and integration of TB and HIV services could improve TB treatment outcomes, particularly among adult HIV patients not taking ART.

Mortality and associated factors among patients with TB-HIV co-infection in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Tuberculosis (TB) and human immunodeficiency virus (HIV) co-infection is a major public health problem in Ethiopia. Patients with TB-HIV co-infection have significantly higher mortality rates compared to those with TB or HIV mono-infection. This systematic review and meta-analysis aim to summarize the evidence on mortality and associated factors among patients with TB-HIV co-infection in Ethiopia.

METHODS

Comprehensive searches were conducted in multiple electronic databases (PubMed/MEDLINE, Embase, CINAHL, Web of Science) for observational studies published between January 2000 and present, reporting mortality rates among TB/HIV co-infected individuals. Two reviewers performed study selection, data extraction, and quality assessment independently. Random-effects meta-analysis was used to pool mortality estimates, and heterogeneity was assessed using I² statistics. Subgroup analyses and meta-regression were performed to explore potential sources of heterogeneity.

RESULTS

185 articles were retrieved with 20 studies included in the final analysis involving 8,113 participants. The pooled mortality prevalence was 16.65% (95% CI 12.57%-19.65%) with I2 : 95.98% & p-value < 0.00. Factors significantly associated with increased mortality included: older age above 44 years (HR: 1.82; 95% CI: 1.31-2.52), ambulatory(HR: 1.64; 95% CI: 1.23-2.18) and bedridden functional status(HR: 2.75; 95% CI: 2.01-3.75), extra-pulmonary Tuberculosis (ETB) (HR: 2.34; 95% CI: 1.76-3.10), advanced WHO stage III (HR: 1.76; 95% CI: 1.22-2.38) and WHO stage IV (HR: 2.17; 95% CI:1.41-3.34), opportunistic infections (HR: 1.75; 95% CI: 1.30-2.34), low CD4 count of < 50 cells/mm3 (HR: 3.37; 95% CI: 2.18-5.22) and lack of co-trimoxazole prophylaxis (HR: 2.15; 95% CI: 1.73-2.65).

CONCLUSIONS

TB/HIV co-infected patients in Ethiopia experience unacceptably high mortality, driven by clinical markers of advanced immunosuppression. Early screening, timely treatment initiation, optimizing preventive therapies, and comprehensive management of comorbidities are imperative to improve outcomes in this vulnerable population.

Tuberculosis-associated mortality and risk factors for HIV-infected population in Ethiopia: a systematic review and meta-analysis

Background

Despite the effectiveness of antiretroviral therapy in reducing mortality from opportunistic infections among people living with HIV (PLHIV), tuberculosis (TB) continues to be a significant cause of death, accounting for over one-third of all deaths in this population. In Ethiopia, there is a lack of comprehensive and aggregated data on the national level for TB-associated mortality during co-infection with HIV. Therefore, this systematic review and meta-analysis aimed to estimate TB-associated mortality and identify risk factors for PLHIV in Ethiopia.

Methods

We conducted an extensive systematic review of the literature using the Preferred Reporting of Systematic Review and Meta-Analysis (PRISMA) guidelines. More than seven international electronic databases were used to extract 1,196 published articles from Scopus, PubMed, MEDLINE, Web of Science, HINARY, Google Scholar, African Journal Online, and manual searching. The pooled mortality proportion of active TB was estimated using a weighted inverse variance random-effects meta-regression using STATA version-17. The heterogeneity of the articles was evaluated using Cochran's Q test and I 2 statistic test. Subgroup analysis, sensitivity analysis, and Egger's regression were conducted to investigate publication bias. This systematic review is registered in Prospero with specific No. CRD42024509131.

Results

Overall, 22 individual studies were included in the final meta-analysis reports. During the review, a total of 9,856 cases of TB and HIV co-infection were screened and 1,296 deaths were reported. In the final meta-analysis, the pooled TB-associated mortality for PLHIV in Ethiopia was found to be 16.2% (95% CI: 13.0-19.2, I 2 = 92.9%, p = 0.001). The subgroup analysis revealed that the Amhara region had a higher proportion of TB-associated mortality, which was reported to be 21.1% (95% CI: 18.1-28.0, I 2 = 84.4%, p = 0.001), compared to studies conducted in Harari and Addis Ababa regions, which had the proportions of 10% (95% CI: 6-13.1%, I 2 = 83.38%, p = 0.001) and 8% (95% CI: 1.1-15, I 2 = 87.6%, p = 0.001), respectively. During the random-effects meta-regression, factors associated with co-infection of mortality in TB and HIV were identified, including WHO clinical stages III & IV (OR = 3.01, 95% CI: 1.9-4.7), missed co-trimoxazole preventive therapy (CPT) (OR = 1.89, 95% CI: 1.05-3.4), and missed isoniazid preventive therapy (IPT) (OR = 1.8, 95% CI: 1.46-2.3).

Conclusion

In Ethiopia, the mortality rate among individuals co-infected with TB/HIV is notably high, with nearly one-fifth (16%) of individuals succumbing during co-infection; this rate is considered to be higher compared to other African countries. Risk factors for death during co-infection were identified; the included studies examined advanced WHO clinical stages IV and III, hemoglobin levels (≤10 mg/dL), missed isoniazid preventive therapy (IPT), and missed cotrimoxazole preventive therapy (CPT) as predictors. To reduce premature deaths, healthcare providers must prioritize active TB screening, ensure timely diagnosis, and provide nutritional counseling in each consecutive visit.

Impact of HIV coinfection on tuberculosis treatment outcomes in Ethiopia: a systematic review and meta-analysis

OBJECTIVES

Despite the implementation of a short-term direct observation treatment programme, HIV coinfection is one of the main determinants of tuberculosis (TB) treatment success. This meta-analysis was conducted to report the impact of HIV on TB treatment outcomes using inconsistent and variable study findings.

DESIGN

Systematic review and meta-analysis was performed.

DATA SOURCES

The PubMed/Medline, Web of Science and Google Scholar databases were used to access the articles. The Joanna Briggs Institute (JBI) Meta-Analysis of Statistics Assessment and Review Instrument was used for the critical appraisal.

ELIGIBILITY CRITERIA

All observational studies conducted in Ethiopia and reporting TB treatment outcomes in relation to HIV coinfection were included in the final analysis.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted the data using a standardised data extraction format. The JBI critical appraisal tool was used to assess the quality of primary studies. Stata V.14 was used for the data analysis. Cochran's Q statistic with inverse variance (I2) and funnel plot are used to assess the presence of heterogeneity (I2=94.4%, p<0.001) and publication bias, respectively. A random effect model was used to estimate TB treatment outcomes with a 95% CI.

RESULTS

The overall success rate of TB treatment was 69.9% (95% CI 64% to 75%). The cure rate of TB among patients living with HIV was 19.3%. Furthermore, the odds of unsuccessful treatment among TB-HIV coinfected patients were 2.6 times greater than those among HIV nonreactive patients (OR 2.65; 95% CI 2.1 to 3.3).

CONCLUSION

The success of TB treatment among patients living with HIV in Ethiopia was lower than the WHO standard threshold (85%). HIV coinfection hurts TB treatment success. Therefore, collaborative measurements and management, such as early treatment initiation, follow-up and the management of complications, are important.

Burden of HIV and treatment outcomes among TB patients in rural Kenya: a 9-year longitudinal study

BACKGROUND

Although tuberculosis (TB) patients coinfected with HIV are at risk of poor treatment outcomes, there is paucity of data on changing trends of TB/HIV co-infection and their treatment outcomes. This study aims to estimate the burden of TB/HIV co-infection over time, describe the treatment available to TB/HIV patients and estimate the effect of TB/HIV co-infection on TB treatment outcomes.

METHODS

This was a retrospective data analyses from TB surveillance in two counties in Kenya (Nyeri and Kilifi): 2012‒2020. All TB patients aged ≥ 18 years were included. The main exposure was HIV status categorised as infected, negative or unknown status. World Health Organization TB treatment outcomes were explored; cured, treatment complete, failed treatment, defaulted/lost-to-follow-up, died and transferred out. Time at risk was from date of starting TB treatment to six months later/date of the event and Cox proportion with shared frailties models were used to estimate effects of TB/HIV co-infection on TB treatment outcomes.

RESULTS

The study includes 27,285 patients, median (IQR) 37 (29‒49) years old and 64% male. 23,986 (88%) were new TB cases and 91% were started on 2RHZE/4RH anti-TB regimen. Overall, 7879 (29%, 95% 28‒30%) were HIV infected. The proportion of HIV infected patient was 32% in 2012 and declined to 24% in 2020 (trend P-value = 0.01). Uptake of ARTs (95%) and cotrimoxazole prophylaxis (99%) was high. Overall, 84% patients completed six months TB treatment, 2084 (7.6%) died, 4.3% LTFU, 0.9% treatment failure and 2.8% transferred out. HIV status was associated with lower odds of completing TB treatment: infected Vs negative (aOR 0.56 (95%CI 0.52‒0.61) and unknown vs negative (aOR 0.57 (95%CI 0.44‒0.73). Both HIV infected and unknown status were associated with higher hazard of death: (aHR 2.40 (95%CI 2.18‒2.63) and 1.93 (95%CI 1.44‒2.56)) respectively and defaulting treatment/LTFU: aHR 1.16 (95%CI 1.01‒1.32) and 1.55 (95%CI 1.02‒2.35)) respectively. HIV status had no effect on hazard of transferring out and treatment failure.

CONCLUSION

The overall burden of TB/HIV coinfection was within previous pooled estimate. Our findings support the need for systematic HIV testing as those with unknown status had similar TB treatment outcomes as the HIV infected.

Impact of HIV-AIDS on tuberculosis treatment outcome in Southern Ethiopia - A retrospective cohort study

BACKGROUND

Globally, the Tuberculosis treatment success rate was worse for HIV-positive TB patients compared with HIV- negative TB patients. This study aimed at determining the impact of HIV-AIDS and factors associated with TB treatment outcomes.

METHODS

This study was a retrospective cohort study of five years of tuberculosis data from four public health facilities in Hosanna Town. A total of 604 study participants were included using a systematic random sampling technique. Descriptive analysis of ratios, rates, and proportions was done and binary logistic regression, bivariable and multivariable, analysis was also done.

RESULT

A total of 604 TB patients were enrolled in this study. 302 (50%) were HIV co-infected. The overall treatment success rate was 90.1% (544/604). Treatment success rates are 86.4% (261/302) for TB-HIV co-infected patients and 93.7% (283/302) for non-co-infected patients. TB-HIV co-infected patients had a higher risk of an unsuccessful treatment outcome (Adjusted Relative Risk [ARR]: 2.7; 95% Confidence Interval [CI]: 1.4 - 5.2). The risk of unsuccessful treatment outcome is also higher among rural residents (ARR: 3.3; CI: 1.4 - 5.0), patients on the re-treatment category (ARR: 2.7; CI: 1.4 - 5.1), and with chronic disease (ARR: 3.3; CI: 1.3 - 8.1).

CONCLUSION

TB treatment success rate is good as compared to the WHO minimum requirement. Successful treatment outcome is lower among patients with HIV infection, rural residents, patients on re-treatment, and patients with chronic disease. Therefore, due emphasis should be given to these high-risk groups.

Trends and outcomes of tuberculosis among cases on directly observed short course treatment (DOTS) at Tepi public health center Southwest Ethiopia

BACKGROUND

Determining the trends and treatment outcomes of TB in health facilities is very important to inform better management of the disease and control efforts. Nevertheless, data from the rural, urban and suburban settings of Ethiopia show variability and inconsistency. This study was designed to evaluate trends and treatment outcomes of tuberculosis patients at Tepi Health Center and to identify the predictors of unsuccessful treatment outcome.

METHOD

Retrospective review of TB cases registered in Tepi health center between June 2011 and May 2018 was conducted using data extracted from medical records of TB patients. Structured data extraction form was prepared and used to extract socio-demographic, clinical and outcome data of study cases. Case definition and the treatment outcome of patients were ascertained and reported in accordance with World Health Organization guideline. Binary logistic regression model was fit to identify predictors of unsuccessful outcome.

RESULTS

A total of 1651 TB patients registered at Tepi Public Health Center in between June 2011 and May 2018, were included in the study. Of all 924 (56%) were males and 1053 (63.8%) cases were in between the age range of 15 and 35 years. HIV-status of 1019 TB cases were unknown and 189 (11.4%) of participants were HIV-positive. Four hundred fifty seven (27.7%) cases were diagnosed with extra pulmonary TB (EPTB) and 1194 (72.3%) were pulmonary TB patients out of which, 376 (73.6%) were smear-positive pulmonary TB (PTB+). Overall treatment success rate (TSR) of patients was 80.4% (1327/1651), while it was 84.8% (134/158), 80.2% (410/511), and 78.3% (148/189) among the transfer-in, PTB+, and HIV + cases, respectively. Higher numbers of successful treatment outcomes were recorded among new patients (82.7%) and EPTB cases (84.7%). The cure rate were 73.6% (376/511) and 18% (34/189) among patients with PTB+ and HIV+, respectively. Multiple logistic regression analysis indicated that residence sites (OR 0.763 (0.584, 0.996) and TB/HIV co-infection (OR 0.661 (0.444, 0.985), were significantly associated with the treatment outcome. Rural residence was 27.1% less likely to have successful treatment. There was significant heterogeneity in the odds of having successful treatment outcomes across years of initiating treatment.

CONCLUSION

Treatment success rate among study cases was lower than the WHO's target and further efforts like availability of TB clinics in nearby sites and reducing rate of HIV infection should be made to improve rate of successful treatment outcome.

Negative Impact Factors in HIV-Tuberculosis

About one quarter of all tuberculosis (TB) deaths are among people living with HIV. Tuberculosis is a leading infectious cause of death among persons infected with HIV and the outcome of TB treatment is poorer in these patients. Objective: To identify the factors associated with a poor tuberculosis outcome in patients with HIV-TB coinfection. Material and methods: This is a retrospective cohort study using data from the local TB registry for 2009-2016. We performed descriptive statistics as well as univariate and multivariate analysis. Results: During the study period we identified 86 patients (4.76% of all patients registered for TB treatment) with HIV-TB who had a mean age of 35.05±9.10 years and were mostly male (73.25%). More than half of patients were current drug users (51.16%) and 22.10% homeless. The mean CD4 value was 179.11±204.76/mm3 and 69.76% of patients received antiretroviral treatment during TB treatment. Viral hepatitis was present in 61.62% of cases, and 77.9% of patients were new TB cases. Pulmonary TB was noted in 72 cases, with confirmation by culture being obtained in 84.44% of cases. Treatment success was achieved in 63.95% of cases, 22.09% of patients died, 8.13% abandoned treatment, and 5.81% were lost to follow up. Several factors related to poor outcome were identified by univariate analysis, including drug use (OR=3.14, p=0.027), homeless status (OR=3.01, p=0.039) and viral hepatitis (OR=2.93, p=0.045). Multivariate analysis revealed marginal insignificance for homeless status (p=0.06) and drug use (p=0.86). Conclusion: A special attention and dedicated programs should be considered for patients who are intravenous drug users or those without a stable home.

Tuberculosis Treatment Outcome in Patients with TB-HIV Coinfection in Kuala Lumpur, Malaysia

Background

Tuberculosis (TB) is a serious health threat to people living with human immunodeficiency virus (HIV). This study aimed to identify the characteristics, unsuccessful TB treatment rate, and determinants of unsuccessful TB treatment outcome among patients with TB-HIV coinfection in Kuala Lumpur.

Methods

This was a cross-sectional study. The data of all patients with TB-HIV in the federal territory of Kuala Lumpur from 2013 to 2017 were collected and reviewed. The data were retrieved from the national database (TB Information System) at the Kuala Lumpur Health Department from 1 March 2018 to 31 May 2018.

Results

Out of 235 randomly selected patients with TB-HIV, TB treatment outcome was successful in 57.9% (cured and completed treatment) and unsuccessful in 42.1% (died, failed, or lost to follow-up). Patients who did not receive DOTS (directly observed treatment, short course) (adjusted odds ratio: 21.71; 95% confidence interval: 5.36–87.94) and those who received shorter treatment duration of <6 months (aOR: 34.54; 95% CI: 5.97–199.93) had higher odds for unsuccessful TB treatment outcome.

Conclusions

Nearly half of the patients with TB-HIV had unsuccessful TB treatment outcome. Therefore, it is important to ensure that such patients receive DOTS and continuous TB treatment of >6 months. It is crucial to strengthen and widen the coverage of DOTS, especially among high-risk groups, in healthcare settings. Strict follow-up by healthcare providers is needed for patients with TB-HIV to gain treatment adherence and for better rates of successful TB treatment.

Factors predictive of the success of tuberculosis treatment: A systematic review with meta-analysis

OBJECTIVE

To produce pooled estimates of the global results of tuberculosis (TB) treatment and analyze the predictive factors of successful TB treatment.

METHODS

Studies published between 2014 and 2019 that reported the results of the treatment of pulmonary TB and the factors that influenced these results. The quality of the studies was evaluated according to the Newcastle-Ottawa quality assessment scale. A random effects model was used to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). This review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) in February 2019 under number CRD42019121512.

RESULTS

A total of 151 studies met the criteria for inclusion in this review. The success rate for the treatment of drug-sensitive TB in adults was 80.1% (95% CI: 78.4-81.7). America had the lowest treatment success rate, 75.9% (95% CI: 73.8-77.9), and Oceania had the highest, 83.9% (95% CI: 75.2-91.0). In children, the success rate was 84.8% (95% CI: 77.7-90.7); in patients coinfected with HIV, it was 71.0% (95% CI: 63.7-77.8), in patients with multidrug-resistant TB, it was 58.4% (95% CI: 51.4-64.6), in patients with and extensively drug-resistant TB it was 27.1% (12.7-44.5). Patients with negative sputum smears two months after treatment were almost three times more likely to be successfully treated (OR 2.7; 1.5-4.8), whereas patients younger than 65 years (OR 2.0; 1.7-2.4), nondrinkers (OR 2.0; 1.6-2.4) and HIV-negative patients (OR 1.9; 1.6-2.5 3) were two times more likely to be successfully treated.

CONCLUSION

The success of TB treatment at the global level was good, but was still below the defined threshold of 85%. Factors such as age, sex, alcohol consumption, smoking, lack of sputum conversion at two months of treatment and HIV affected the success of TB treatment.

Treatment Outcome of Tuberculosis and Associated Factors among TB-HIV Co-Infected Patients at Public Hospitals of Harar Town, Eastern Ethiopia. A five-year retrospective study

BACKGROUND

The bidirectional relationship between the twin epidemics of Tuberculosis (TB) and Human Immunodeficiency Virus (HIV) causes major global health challenges in the twenty-first century. TB-HIV co-infected people are facing multifaceted problems like high lost to follow up rates, poor treatment adherence, high TB recurrence rate, and high mortality risk. Our objective was to assess the outcomes of TB treatment and associated factors among TB-HIV co-infected patients in Harar town, Eastern part of Ethiopia, 2018.

METHODS

A retrospective study was conducted among systematically selected 349 TB/HIV co-infected patients who registered from 2012 to 2017 in two public hospitals in Harar town. The data were collected through document review by using a pre-tested structured data extraction checklist. The data were analyzed using SPSS Version 21. Bivariate and multivariate logistic regression were determined at 95% confidence intervals.

RESULTS

Among the 349 TB/HIV co-infected patients included in the study, 30.1% were cured, 56.7% had completed their treatment, 7.7% died, 1.7% were lost to follow up, and 3.7% were treatment failure. Overall, 86.8% of the TB-HIV co-infected patients had successful TB treatment outcomes. The patients who were on re-treatment category (AOR = 2.91, 95% CI: 1.17-7.28), who had a history of opportunistic infection (AOR = 3.68, 95% CI: 1.62-8.33), and who did not take co-trimoxazole prophylaxis (AOR = 3.54, 95% CI: 1.59-7.89) had 2.91, 3.68, and 3.54 times higher odds of having unsuccessful TB treatment outcome than their counterparties, respectively. The chance of unsuccessful TB treatment outcome was 4.46 (95% CI: 1.24-16.02), 5.94 (95% CI: 1.87-18.85), and 3.01 (95% CI: 1.15-7.91) times higher among TB/HIV patients in stage 2, 3 and 4 than those in stage 1, respectively.

CONCLUSIONS

The overall rate of the success of the TB treatment among TB-HIV co-infected patients in this study was higher compared with many previous studies. TB/HIV patients with a history of previous TB treatment, smear-positive pulmonary TB, late HIV stage, history of opportunistic infection and not being on co-trimoxazole prophylaxis therapy were at a high risk of getting poor treatment outcomes.

Tuberculosis treatment outcome and its associated factors among people living with HIV and AIDS in Fako Division of Cameroon

Background

Tuberculosis (TB) and HIV co-infection challenges treatment and worsens the outcome of TB treatment. This study aimed to assess the outcome of TB treatment and factors facilitating treatment success among people living with HIV/AIDS in Fako Division of the South West Region of Cameroon.

Methods

A hospital-based retrospective cohort study was conducted by manually reviewing medical records of HIV/TB co-infected patients from January 2010 to September 2017. A structured data collection form was used to review the medical records of HIV patients co-infected with TB aged 10 years and older. Patients with incomplete files were dropped from the study. Treatment success was defined as the sum of patients who were declared cured and those who had completed treatment, as per the World Health Organization’s recommendations. Data were analyzed using Statistical Package for Social Sciences version 21. Bivariate and multivariate logistic regression model was carried out to identify factors facilitating successful TB treatment outcome. Significance was obtained through adjusted odds ratio with its 95% confidence interval and a p<0.05.

Results

A total of 2,986 files were reviewed but 2,928 (98.1%) were retained. Out of the 2,928 medical files of adult TB patients reviewed, 1,041 (35.6%, [95% CI 33.8%-37.3%]) were HIV/TB co-infected. The 1,041 co-infected patients had a mean age of 37.07 (SD of10.02) years and 56.3% were females. The treatment outcome of TB patients were 795(76.4%) cured, 23(2.2%) treatment completed, 99(9.5%) were lost to follow-up, 16 (1.5%) failed, 72(6.9%) died and 36(3.5%) transferred out. A successful treatment outcome was achieved in 818(78.6%,[95% CI: 76.0%–81.0%]) patients. Being a female [COR 1.61, 95% CI: 1.19–2.17, p = 0.002], receiving TB treatment in 2014 [COR 2.00, 95% CI: 1.11–3.60, p = 0.021] and 2015 [COR 2.50, 95% CI: 1.39–4.50, p = 0.002], having relapsed TB infection [COR 0.46, 95% CI: 0.23–0.93, p = 0.031], receiving ART [COR 1.95, 95% CI: 1.28–2.97, p = 0.002] and Cotrimoxazole [COR 2.03, 95% CI: 1.12–3.66, p = 0.019] were factors significantly associated with successful treatment. After adjusting for confounders, successful treatment outcome were associated with being a female [AOR 1.6; 95% CI: 1.21–2.22, p = 0.001], diagnosis of TB in 2014 [AOR 1.90; 95% CI: 1.04–3.45, p = 0.036] and 2015 [AOR 2.43; 95% CI: 1.33–4.43, p = 0.004].

Conclusion

There is a high TB treatment success rate among HIV/TB co-infected patients in our setting, although below the target set by the WHO. Specific interventions aimed at enhancing patient outcomes are recommended.

Unsuccessful treatment in pulmonary tuberculosis: factors and a consequent predictive model

Background

Cure is particularly valuable in pulmonary cases (PTB), as unsuccessful treatment fuels incidence and resistance to antibiotics. This study aims to identify individual factors of PTB unsuccessful treatment in Portugal and to develop a consequent predictive model.

Methods

Using the Portuguese TB surveillance database (SVIG-TB), PTB cases older than 15 years notified from 2000 to 2012 in Continental Portugal were analyzed. Unsuccessful treatment included the WHO categories (failure, default, death and transferred out). Based on a literature review, predictors involved sociodemographic, behavioral, disease-related and treatment-related factors. Binary logistic regression was used to estimate unsuccessful treatment factors and to develop the predictive risk model.

Results

The unsuccessful outcome rate in PTB patients was of 11.9%. The predictive model included the following factors: TB/HIV co-infection (OR 4.93), age over 64 years (OR 4.37), IV drugs abuse (OR 2.29), other diseases (excluding HIV and Diabetes, OR 2.09) and retreatment (OR 1.44), displaying a rather good validity.

Conclusion

The overall treatment unsuccessful treatment rate in PTB patients complies with the 85% WHO success threshold. The predictive model of unsuccessful treatment proved well. Nomogram representation allows an early, intuitive identification of PTB patients at increased risk. The model is liable to widespread use as a prognostic tool.

Protocol for systematic review and meta-analysis of treatment success rate among adult patients with tuberculosis in sub-Saharan Africa

INTRODUCTION

Tuberculosis (TB) is a leading cause of mortality globally. Despite being curable, treatment success rates (TSRs) among adult patients with bacteriologically confirmed pulmonary TB (BC-PTB) in sub-Saharan Africa (SSA) differ considerably. This protocol documents and presents an explicit plan of a systematic review and meta-analysis to summarise TSR among adult patients with BC-PTB in SSA.

METHODS AND ANALYSIS

Two reviewers will search and extract data from MEDLINE, EMBASE, Ovid, Cumulative Index to Nursing and Allied Health Literature and Web of Science electronic databases. Observational and interventional studies published between 1 July 2008 and 30 June 2018, involving adult patients with BC-PTB will be eligible. Data abstraction disagreements will be resolved by consensus with a third reviewer, while percentage agreement computed with kappa statistics. TSR will be computed with Metaprop, a Stata command for pooling proportions using DerSimonian and Laird random effects model and presented in a forest plot with corresponding 95% CIs. Heterogeneity between included studies will be assessed with Cochran's Q test and quantified with I-squared values. Publication bias will be evaluated with funnel plots and tested with Egger's weighted regression. Time trends in TSR will be calculated with cumulative meta-analysis.

ETHICS AND DISSEMINATION

No ethical approval will be needed because data from previous published studies in which informed consent was obtained by primary investigators will be retrieved and analysed. We will prepare a manuscript for publication in a peer-reviewed journal and present the results at conferences.

Poor treatment outcomes and its determinants among tuberculosis patients in selected health facilities in East Wollega, Western Ethiopia

BACKGROUND

Although it is a preventable and treatable disease, tuberculosis remains a major medical and public health problem throughout the world. The control and elimination of tuberculosis is currently challenged by the development and spread of antituberculosis drug resistance. The resistance is often correlated to the absence of properly implemented control measures that lead to poor treatment outcomes. Therefore, the aim of the current study was to assess poor treatment outcomes and its determinants among tuberculosis patients in selected health facilities in East Wollega zone, Western Ethiopia.

METHOD

A five-year retrospective cross-sectional study design was employed. Data were collected from patients' medical record from January to March 2017. Data were entered and analyzed using SPSS version 20. Descriptive statistics were used to generate and summarize frequencies. Univariate and multivariate logistic regression analysis were used to associate the potential determinants of poor treatment outcomes.

RESULTS

From 995 patients with documented treatment outcomes, 58.9% were males with a mean age of 31.9±16.3 years and 58% lived in rural areas. Majorities of cases (95.7%) were newly treated ones. Nearly half of the cases had extrapulmonary tuberculosis and 6.8% were co-infected with HIV. Nearly three-quarter of patients had completed their treatment while 17.2%, 2.9%, 4.8%, 0.4% patients were cured, defaulted, died, and failed, respectively. The overall treatment success rate was 91.9%. Being treated in Anger Gute health center (adjusted odds ratio (AOR): 2.27; 95% confidence interval (CI): 1.18-4.38); male (AOR: 1.81; 95% CI: 1.06-3.10); lived in rural areas (AOR: 1.73; 95% CI: 1.02-2.91); previously treated (AOR: 2.72; 95% CI: 1.16-6.39) and unknown HIV status (AOR: 4.56; 95% CI: 1.98-10.50) were determinants of poor treatment outcomes.

CONCLUSION

The current treatment success rate was exceeded the recommended target. However, special attention and strict follow up is required for tuberculosis patients with high risk of unsuccessful treatment outcomes including male, rural resident, previously treated and unknown in HIV status patients throughout their treatment periods.

Drug-susceptible tuberculosis treatment success and associated factors in Ethiopia from 2005 to 2017: a systematic review and meta-analysis

OBJECTIVES

The main aim of this study was to assess the overall tuberculosis (TB) treatment success in Ethiopia and to identify potential factors for poor TB treatment outcome.

DESIGN

A systematic review and meta-analysis of published literature was conducted. Original studies were identified through a computerised systematic search using PubMed, Google Scholar and Science Direct databases. Heterogeneity across studies was assessed using Cochran's Q test and I² statistic. Pooled estimates of treatment success were computed using the random-effects model with 95% CI using Stata V.14 software.

RESULTS

A total of 230 articles were identified in the systematic search. Of these 34 observational studies were eligible for systematic review and meta-analysis. It was found that 117 750 patients reported treatment outcomes. Treatment outcomes were assessed by World Health Organization (WHO) standard definitions of TB treatment outcome. The overall pooled TB treatment success rate in Ethiopia was 86% (with 95% CI 83%_88%). TB treatment success rate for each region showed that, Addis Ababa (93%), Oromia (84%), Amhara (86%), Southern Nations (83%), Tigray (85%) and Afar (86%). Mainly old age, HIV co-infection, retreatment cases and rural residence were the most frequently identified factors associated with poor TB treatment outcome.

CONCLUSION

The result of this study revealed that the overall TB treatment success rate in Ethiopia was below the threshold suggested by WHO (90%). There was also a discrepancy in TB treatment success rate among different regions of Ethiopia. In addition to these, HIV co-infection, older age, retreatment cases and rural residence were associated with poor treatment outcome. In order to further improve the treatment success rate, it is strategic to give special consideration for regions which had low TB treatment success and patients with TB with HIV co-infection, older age, rural residence and retreatment cases.

Effect of clients Strategic Index Case Testing on community-based detection of HIV infections (STRICT study)

BACKGROUND

Strategic Index Case Testing (STRICT), a form of partner notification service, was initiated to track, identify and notify sexual partners of people living with HIV (Index clients) with the sole aim of testing them to determine their HIV status and linking clients who are positive to Anti-Retroviral Therapy (ART). This research analyzed the HIV sero-prevalence among sexual partners of HIV positive clients using STRICT and determines the role of STRICT in HIV epidemic control.

METHODS

This is a non-control Interventional study that determined the impact of Strategic Index Case Testing (STRICT) on detecting previously undiagnosed HIV infections among sexual partners of positive index clients. This study was conducted in seven Local Government Areas (LGAs) of Karu, Nasarawa, Lafia, Doma, AMAC, Bwari, and Ushongo. These LGAs were selected for HIV epidemic control due to projected high prevalence of HIV from previous program level data. HTS was offered to sexual partners of index PLHIV from facility and community within the LGAs. Index clients were PLHIV diagnosed from outreaches, hot spots set up in strategic places and Provider Initiated Testing and Counseling (PITC) in comprehensive and primary health care facilities. Newly diagnosed PLHIV and those already enrolled and commenced on ART from October 2015 to July 2016 were identified from source registers. These index clients were counseled on how to notify their sexual partners about their HIV status and on bringing them for HIV Testing and Counseling (HTS). Those unable to do so after a given period of time were assisted by health workers in informing their various sexual partners based on the confidential agreement and informed consent signed by the Index clients.

FINDINGS

A total of 1277 index cases were counseled and interviewed with 879 index clients agreeing to disclosure, giving a disclosure rate of 68.3%. We identified 888 sexual partners from the interviews and traced 870 (97.9%) sexual contacts. A total of 741 (85.2%) of 870 sexual contacts traced were tested for HIV, out of which 378 (51%) tested positive using an HIV rapid test kit, and this was statistically significant at P Value=0.0254. A total of 348 (92.1%) out of 378 HIV positive sexual partners were immediately commenced on ART using the recommended UNAIDS Test and Treat approach to HIV epidemic control.

INTERPRETATION

STRICT identifies the need for reaching out to sexual partners of index clients and providing them with HIV Testing Services (HTS) as they belong to a high risk priority population and also linking them to care and treatment. This group of people must be reached with HTS strategies in order to end the HIV epidemic as evidenced by high sero-prevalence of 51% among them.

Treatment outcome of tuberculosis among Human Immunodeficiency Virus positive patients in Eastern Ethiopia: a retrospective study

Introduction

Tuberculosis is the leading cause of morbidity and mortality among people living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome worldwide. Although Human Immunodeficiency Virus related tuberculosis is both treatable and preventable, incidence rates continue to climb in developing countries where both infections are endemic. The aim of this study was to assess the treatment outcome of tuberculosis among Human Immunodeficiency Virus positive patients attending in three hospitals of Eastern Ethiopia.

Methods

A retrospective clinical record review was conducted for 627 Tuberculosis and Human immunodeficiency virus co-infected patients registered from January 2008 to January 2014 cards were reviewed in three hospitals of tuberculosis clinics of Eastern Ethiopia from December 2015 to February 2016. The three hospitals were selected based on their high patient load of TB-HIV co infection and the presence of ART and TB units. Data on patient's details and tuberculosis treatment outcome were collected using standardized report format of National Tuberculosis and Leprosy Control Programme (NTLCP). The collected data were analyzed by Statistical Package for Social Sciences (SPSS) software Version 16.

Results

The overall treatment success rate was 78.3%. Of the total TB-HIV co infected study participants, 17.9% cured, 60.4% treatment completed, 8.6% died, 0.6% failure, 1.8% defaulter and 10.7% transferred out. Those participants in the age groups of less than or equals to 18 years old (Adjusted Odds Ratio = 1.990, 95% Confidence Interval: 1.01, 3.350), extra pulmonary tuberculosis (Adjusted Odds Ratio = 1.51, 95% Confidence Interval = 1.12, 3.42), on antiretro viral therapy (Adjusted Odds Ratio = 1.54, 95% Confidence Interval = 1.252, 3.910) were more likely to have higher treatment outcome than each of the above variables counter parts.

Conclusion

The rate of treatment success in this study was lower than recommended rate by World Health Organization. Thus this study recommends improving counseling during tuberculosis treatment, providing home visits and motivation of patients, improving defaulter tracing and health information dissemination in order to reduce treatment interruption.

Tuberculosis treatment outcomes in Ethiopia from 2003 to 2016, and impact of HIV co-infection and prior drug exposure: A systematic review and meta-analysis

Background

Knowledge of tuberculosis (TB) treatment outcomes is substantially needed to assess the performance of national TB controls programs (NTPs). To date, the overall estimates of treatment outcomes have not been determined in Ethiopia. Therefore, this meta-analysis was undertaken to produce pooled estimates of TB treatment outcomes and to analyze the impact of prior anti-TB drug exposure and HIV co-infection.

Methods

Potentially relevant studies were retrieved from PubMed, EMBASE, and MEDLINE online databases. The unpublished studies have been retrieved from the grey literature through Google and Google Scholar. The pooled estimates were calculated using random effect model. The summary estimates were also presented using Forest plots and Tables. The outcome measures were successful and unsuccessful treatment outcomes. Patients who were cured or with completed treatment defined as successful treatment outcome and patients meeting the definition of death, defaulting and failure are considered as unsuccessfully treated cases.

Results

A total of 34 studies are included for meta-analysis. The pooled estimate of successful TB treatment outcomes amounts to 83.7% (95% CI 81.1%–86.3%). Of successfully treated cases, 33.9% were cured and the remaining completed cases. Besides, among patients with unsuccessful treatment outcome, nearly 50% were dead and the rest were treatment failures and defaulters. Sub-group analysis shows that high treatment success rate was estimated in Afar; 88.9% (95% CI 83.8%–94.2%), followed by Oromia; 88.5% (95% CI 82.6%–94.5%) and Gambella; 86.1% (95% CI 84.4%–87.9%), whereas relatively poor treatment outcome was noted in Tigray; 20.0% (95% CI 2.1%–37.9%) and Amhara; 19.0% (95% CI 12.6%–25.5%). The unsuccessful TB treatment outcome was found to be higher among HIV/TB co-infected cases with an odds ratio of 1.98 (95%CI, 1.56–2.52) and re-treated cases with an odds ratio of 2.17 (95%CI, 1.55–3.03). The time trend was assessed from 2003 to 2016, but it shows insignificant variation with treatment outcome (P = 0.108).

Conclusion

The rate of successful treatment outcome in Ethiopia appears generally high, only slightly below the threshold suggested by the World Health Organization. History of tuberculosis treatment and HIV/TB co-infection were inversely associated with favorable treatment outcomes.

Treatment outcomes of tuberculosis patients under directly observed treatment short-course at Debre Tabor General Hospital, northwest Ethiopia: nine-years retrospective study

BACKGROUND

Data regarding tuberculosis (TB) treatment outcomes, proportion of TB/HIV co-infection and associated factors have been released at different TB treatment facilities in Ethiopia and elsewhere in the world as part of the auditing and surveillance service. However, these data are missing for the TB clinic offering directly observed treatment short-course (DOTs) at Debre Tabor General Hospital (DTGH).

METHODS

The authors analysed the records of 985 TB patients registered at the DTGH from September 2008 to December 2016. Data on patients' sex, age, type of TB, and treatment outcomes were extracted from the TB treatment registration logbook. The treatment outcome of patients was categorized according to the National TB and Leprosy Control Program guidelines: cured, treatment completed, treatment failed, died, and not evaluated (transferred out and unknown cases).

RESULTS

Around half of the registered patients were males (516, 52.4%). In terms of TB types, 381 (38.7%), 241 (24.5%), and 363 (36.9%) patients had smear-negative pulmonary TB, smear-positive pulmonary TB, and extra pulmonary TB, respectively. Six hundred and seventy-two patients (90.1%) had successful treatment outcomes (cured and treatment completed), while 74 patients (9.9%) had unsuccessful treatment outcomes (death and treatment failure).TB treatment outcome was not associated with age, sex, type and history of TB, or co-infection with HIV (P > 0.05). The proportion of TB/HIV co-infection was at 24.2%, and these were found to be significantly associated with the age groups of 25-34, 35-44 and ≥65 years:(aOR: 0.44; 95% CI: 0.25-0.8), (aOR: 0.39; 95% CI: 0.20-0.70), (aOR: 4.2; 95% CI: 1.30-12.9), respectively.

CONCLUSIONS

The proportion of patients with successful treatment outcomes was above the World Health Organization target set for Millennium Development Goal of 85% and in line with that of the global milestone target set at > 90% for 2025. Relatively higher proportions of transfer-out cases were recorded in the present study. Similarly, the proportion of TB/HIV co-infection cases was much higher than the national average of 8%.Thus, the health facility under study should develop strategies to record the final treatment outcome of transfer-out cases. In addition, strategies to reduce the burden of TB/HIV co-infection should be strengthened.

Prognostic indicators in the World Health Organization's algorithm for seriously ill HIV-infected inpatients with suspected tuberculosis

BACKGROUND

Criteria for the 2007 WHO algorithm for diagnosing tuberculosis among HIV-infected seriously ill patients are the presence of one or more danger signs (respiratory rate > 30/min, heart rate > 120/min, temperature > 39 °C, and being unable to walk unaided) and cough ≥ 14 days. Determining predictors of poor outcomes among HIV-infected inpatients presenting with WHO danger signs could result in improved treatment and diagnostic algorithms.

METHODS

We conducted a prospective cohort study of inpatients presenting with any duration of cough and WHO danger signs to two regional hospitals in Cape Town, South Africa. The primary outcome was all-cause mortality up to 56 days post-discharge, and the secondary outcome a composite of any one of: hospital admission for > 7 days, died in hospital, transfer to a tertiary level or tuberculosis hospital. We first assessed the WHO danger signs as predictors of poor outcomes, then assessed the added value of other variables selected a priori for their ability to predict mortality in common respiratory opportunistic infections (CD4 count, body mass index (BMI), being on antiretroviral therapy (ART), hypotension, and confusion) by comparing the receiver operating characteristic (ROC) area under the curve (AUC) of the two multivariate models.

RESULTS

484 participants were enrolled, median age 36, 66% women, 53% had tuberculosis confirmed on culture. The 56-day mortality was 13.2%. Inability to walk unaided, low BMI, low CD4 count, and being on ART were independently associated with poor outcomes. The multivariate model of the WHO danger signs showed a ROC AUC of 0.649 (95% CI 0.582-0.717) for predicting 56-day mortality, which improved to ROC AUC of 0.740 (95% CI 0.681-0.800; p = 0.004 for comparison between the two ROC AUCs) with the multivariate model including the a priori selected variables. Findings were similar in sub-analyses of participants with culture-positive tuberculosis and with cough duration ≥ 14 days.

CONCLUSION

The study design prevented a rigorous evaluation of the prognostic value of the WHO danger signs. Our prognostic model could result in improved algorithms, but needs to be validated.

Unsuccessful TB treatment outcomes with a focus on HIV co-infected cases: a cross-sectional retrospective record review in a high-burdened province of South Africa

BACKGROUND

South Africa did not meet the MDG targets to reduce TB prevalence and mortality by 50% by 2015, and the TB cure rate remains below the WHO target of 85%. TB incidence in the country is largely fuelled by the HIV epidemic, and co-infected patients are more likely to have unsuccessful TB treatment outcomes. This paper analyses the demographic and clinical characteristics of new TB patients with unsuccessful treatment outcomes, as well as factors associated with unsuccessful treatment outcomes for HIV co-infected patients.

METHODS

A cross-sectional retrospective record review of routinely collected data for new TB cases registered in the Free State provincial electronic TB database between 2009 and 2012. The outcome variable, unsuccessful treatment, was defined as cases ≥15 years that 'died', 'failed' or 'defaulted' as the recorded treatment outcome. The data were subjected to descriptive and logistic regression analyses.

RESULTS

From 2009 to 2012 there were 66,940 new TB cases among persons ≥15 years (with a recorded TB treatment outcome), of these 61% were co-infected with HIV. Unsuccessful TB treatment outcomes were recorded for 24.5% of co-infected cases and 15.3% of HIV-negative cases. In 2009, co-infected cases were 2.35 times more at risk for an unsuccessful TB treatment outcome (OR: 2.35; CI: 2.06-2.69); this figure decreased to 1.8 times by 2012 (OR: 1.80; CI: 1.63-1.99). Among the co-infected cases, main risk factors for unsuccessful treatment outcomes were: ≥ 65 years (AOR: 1.71; CI: 1.25-2.35); receiving treatment in healthcare facilities in District D (AOR: 1.15; CI 1.05-1.28); and taking CPT (and not ART) (AOR: 1.28; CI: 1.05-1.57). Females (AOR: 0.93; CI: 0.88-0.99) and cases with a CD4 count >350 (AOR: 0.40; CI: 0.36-0.44) were less likely to have an unsuccessful treatment outcome.

CONCLUSIONS

The importance of TB-HIV/AIDS treatment integration is evident as co-infected patients on both ART and CPT, and those who have a higher CD4 count are less likely to have an unsuccessful TB treatment outcome. Furthermore, co-infected patients who require more programmatic attention are older people and males.

Outcome of tuberculosis treatment and its predictors among HIV infected patients in southwest Ethiopia

BACKGROUND

Co-infection with HIV challenges treatment of tuberculosis (TB) and worsens the outcome. This study aimed to assess the outcome of TB treatment and its predictors among HIV infected patients at Mizan-Tepi University Teaching Hospital (MTUTH), Ethiopia.

METHODS

Medical records of 188 TB/HIV co-infected patients who attended the TB clinic of MTUTH from September 2012 to December 2015 were reviewed from March 14 to April 1, 2016. The primary endpoints of the study were treatment outcome of TB and its predictors. Data were analyzed by Statistical Package for Social Sciences version 21. Multivariable binary logistic regression analysis was carried out to identify predictors of treatment outcome. Statistical significance was considered at p-value <0.05.

RESULT

The treatment outcomes of TB patients included in this study were 18 (9.57%) cured, 20 (10.64%) defaulted, 24 (12.77%) died, 39 (20.74%) completed the treatment, and 87 (46.28%) transferred out. A successful treatment outcome was achieved in 57 (30.32%) patients. Initial World Health Organization (WHO) clinical stage III (COR: 2.60; 95%CI: 1.17-5.76) and stage IV (COR: 4.00; 95%CI: 1.29-12.40) were associated with unfavorable outcome. Both WHO stages (III, IV) at the time of HIV diagnosis were independent predictors of poor treatment outcome (AOR: 3.08; 95%CI: 1.14-8.38; AOR: 5.80; 95%CI: 1.36-24.71 respectively). However, smear positive TB was an independent predictor of a favorable treatment outcome (AOR: 2.50; 95%CI: 1.13-5.51).

CONCLUSION

This study revealed that treatment outcome of TB patients was unsatisfactory, which signals a need for improved care. Advanced WHO clinical stages were predictors of poor outcome, while smear positive TB favors good outcome.

Successful TB treatment outcome and its associated factors among TB/HIV co-infected patients attending Gondar University Referral Hospital, Northwest Ethiopia: an institution based cross-sectional study

Background

Tuberculosis/Human immunodeficiency virus (TB/HIV) co-infection is bidirectional and synergistic which mainly affects interventions that have been taken on the area. Tb patients co-infected with HIV have poorer treatment outcome as compared to non-co-infected patients. There is limited information regarding successful TB treatment outcomes and its associated factors; a reason that this study was planned to investigate.

Methods

An institution based cross sectional study was carried out from July 2010 to January 2016. Data were abstracted from patients’ medical chart using data abstraction format. The completeness of the data was checked and cleaned manually. Then, it was entered and analyzed by using SPSS version 20.0. Bi-variable and Multi-variable logistic regression model was fitted to identify factors associated with successful Tb treatment outcome. Significance was obtained through adjusted odds ratio with its 95% CI and a p < 0.05.

Results

Successful TB treatment outcome among TB/HIV co-infected patients in Gondar University Hospital was 77.3% [95%CI 72.6–81.9]. Being residing in outside the Gondar town [AOR = 0.44, 95%CI: 0.25–0.80], having less than the mean baseline weight (<43.7 kg) at initiation of TB treatment [AOR = 0.51, 95% CI: 0.29–0.89], being in the bedridden condition [AOR = 0.23, 95% CI: 0.1–0.23], and experiencing anti-TB treatment side effect [AOR = 0.35, 95% CI: 0.12–0.98] were the factors that resulted the patient in treatment failure.

Conclusion

Successful Tb treatment outcome among TB/HIV co-infected patients was lower than the target set by Global Plan to Stop TB 2011–2015. Strengthening collaborative TB/HIV management activities that would trace the identified factors shall be recommended to increase successful treatment outcome of TB.
