Abstract
Tuberculosis (TB) and human immunodeficiency virus (HIV) coinfection pose significant challenges to global health, particularly in achieving the target of ending TB. However, the impact of HIV status on TB treatment outcomes remains unclear, especially in eastern Ethiopia. This study aimed to assess the treatment outcomes of TB cases by HIV status and associated factors in Haramaya General Hospital from November 15 to December 30, 2022. A retrospective cross-sectional study was conducted, reviewing the TB registry and treatment cards of patients who received anti-TB treatment between September 2017 and August 2022. Of the 420 samples addressed, 91.0% (95% CI: 88.3%-96.7%) of all TB patients had successful treatment outcomes. The treatment success rates of HIV-positive and HIV-negative TB patients were 80.0% and 91.9%, respectively. Being HIV-negative (AOR: 2.561, 95% CI: 1.002-6.542), being in the age group of 20 to 35 years (AOR: 2.950, 95% CI: 1.171-7.431), and urban residence (AOR: 2.961, 95% CI: 1.466-5.981) were associated with the TB treatment success rate. There was a high treatment success rate among all patients with TB. HIV status was associated with TB treatment outcomes. Strengthening TB-HIV collaborative activities, providing patient-centered care and support, and frequent monitoring and evaluation are recommended to improve the TB success rate.

Abstract
Background Ethiopia is one of the countries in the world with the highest rate of tuberculosis (TB). The aim of this study is to describe the characteristics of the patients with TB admitted to a rural hospital in Ethiopia in terms of both diagnosis and clinical management. Methods A retrospective descriptive observational study was conducted. Data were collected from patients older than 13 years who were admitted to the Gambo General Hospital for TB between May 2016 and September 2017. The variables studied were age, sex, symptoms, human immunodeficiency virus (HIV) serology, nutritional status, presence of anemia, chest x-ray or other complementary tests, type of diagnosis (smear microscopy, Xpert MTB-RIF (Cepheid, Sunnyvale, California, USA), or clinical diagnosis), treatment received, outcome, and days of admission. Results One hundred eighty-six patients, aged 13 years and older, were admitted to the TB unit. About 51.6% were female, and the median age was 35 years (interquartile range (IQR) 25-50). Cough was the most frequent symptom on admission (88.7%), and contact with a TB patient was only recognized by 22 patients (11.8%). HIV serology was performed in 148 patients (79.6%); seven were positive (4.7%). About 69.3% met the criteria for malnutrition (body mass index (BMI) <18.5). Most patients, 173 (93%), presented with pulmonary TB and were new cases (94.1%). Patients were diagnosed by clinical parameters in 75% of cases. Smear microscopy was performed in 148 patients, of which 46 (31.1%) were positive, and Xpert MTB-RIF results were only obtained in 16 patients, of which 6 (37.5%) were positive. Chest x-rays were performed in most patients (71%) and were suggestive of TB in 111 (84.1%). The average length of hospital stay was 32 days (confidence interval (CI) 13-50.5). Women tend to be younger than men, have more extrapulmonary TB, and were admitted longer. Nineteen patients died during admission (10.2%). Patients who die were more frequently malnourished (92.9% of those who die were malnourished compared to 67.1% of those who did not die, p = 0.036), tend to be admitted for a shorter time than the survivors and receive more concomitant antibiotic treatment. Conclusions In this rural Ethiopian setting, patients admitted to the hospital for TB are often malnourished (67.1%), the main presentation is pulmonary, mortality is one in 10 admissions and very often receive antibiotics in association with TB treatment (40%).

A qualitative study. PLoS One 2022; 17:e0278592. [PMID: 36584005 PMCID: PMC9803213 DOI: 10.1371/journal.pone.0278592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Accepted: 11/21/2022] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND The main target of tuberculosis control and prevention is to detect incident cases as quickly as possible and also to prevent the occurrence of disease. It is also the responsibility of the health facility to screen the contacts, identifying children for prophylactic therapy. However, the target is difficult to meet due to issues within health facilities that cause health system diagnostic delays. Despite this, there is no information explored why health system diagnostic delays among tuberculosis patients. METHOD A qualitative study was conducted by using different data collection methods and sources. Seventeen DOT providers, five laboratory professionals, six program managers, and seven Tuberculosis patients were interviewed. In addition, 22 governmental health facilities were observed for the availability of resources. Data obtained from the in-depth interviews was transcribed, coded, categorized, and thematized manually. RESULT Health system Diagnosis delays reasons were related with sample collection procedures, poor competency of health professionals, in addition to absences or scarcity of health professionals, medical products, and basic infrastructure. We found 18 health facilities without skilled personnel in the OPD, 7 health facilities with a broken microscope, and almost all health facilities without a separate room for sputum examination. Furthermore, 12 (54.5%) and 14 (63.6%) health facilities lacked access to water and electric power, respectively. CONCLUSION Many reasons for TB diagnosis delays have been identified in the study area. Poor competence of health workers and scarcity of resources were identified. Depending on the finding, we suggest strengthening the health workers' training. Concrete strategies need to be designed to retain professionals. Training on human resource planning and budget preparation is needed for front-line managers. Managers have to work on the maintenance of diagnostic tools and facilitate transportation. The rural health facilities need to use another alternative power source.

Evaluating determinants of treatment outcomes among tuberculosis patients in the mining district of Butha Buthe, Lesotho. IJID REGIONS 2022; 6:62-67. [PMID: 36593894 PMCID: PMC9797408 DOI: 10.1016/j.ijregi.2022.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/21/2022] [Accepted: 12/23/2022] [Indexed: 12/31/2022]
Abstract
Background Before the COVID-19 pandemic, tuberculosis (TB) was the leading infectious cause of death globally. In low- and middle-income countries (LMIC) including Lesotho, treatment outcome is lower than the recommended rate and poor TB treatment outcomes remain a programmatic challenge. The aim of this study was to determine unfavourable treatment outcomes and associated risk factors among TB patients in Butha Buthe district. Methods This was a retrospective record review of TB patients registered between January 2015 and December 2020. Data were collected from TB registers and patients' files and entered Microsoft Excel 2012. Analysis was conducted using R and INLA statistical software. Descriptive statistics were presented as frequencies and percentages. The differences between groups were compared using Pearson's X 2 test in bivariate analysis. Frailty Cox proportional hazards model was used to determine the risk of unfavourable outcomes among the variables. Results A total of 1792 TB patients were enrolled in the study with about 70% males (1,257). Majority (71.7%) of the patients were between 20 and 59 years old, with 48% of the patients being unemployed. Almost a quarter of the patients (23.1%) had unfavourable outcomes with death (342 patients) being the most common unfavourable outcome. Our study has shown that patients older than 59 years, and unemployment increased the risk of having unfavourable treatment outcomes. Death was the most common unfavourable outcome followed by lost-to-follow up. We also observed that the patients in the initiation phase of treatment died at a faster rate compared to those in the continuation phase (p=0.02). Conclusion TB treatment programs should have efficient follow-up methods geared more toward elderly patients. Active case finding to identify population at risk should be part of a TB program which would improve early diagnosis and treatment initiation. Patients in the intensive phase of the treatment program should be monitored more closely to determine adverse drug effects and nutritional requirement to prevent death during this phase of treatment.

BMC Public Health 2022; 22:976. [PMID: 35568853 PMCID: PMC9107690 DOI: 10.1186/s12889-022-13390-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 05/09/2022] [Indexed: 11/10/2022] Open
Abstract
Background Loss to follow-up (LTFU) from tuberculosis (TB) treatment and care is a major public health problem as patients can be infectious and also may develop a multi-drug resistant TB (MDR-TB). The study aimed to assess whether LTFU differs by the distance TB patients travelled to receive care from the nearest health facility. Methods A total of 402 patient cards of TB patients who received care were reviewed from March 1–30, 2020. The Kaplan-Meir curve with the Log-rank test was used to compare differences in LTFU by the distance travelled to reach to the nearest health facility for TB care. The Cox proportional hazard regression model was used to identify predictors. All statistical tests are declared significant at a p-value< 0.05. Results A total of 37 patients were LTFU with the incidence rate of 11.26 per 1000 person-months of observations (PMOs) (95% CI: 8.15–15.53). The incidence rate ratio was 12.19 (95% CI: 5.01–35.73) among the groups compared (those who travelled 10 km or more versus those who travelled less than 10 km). Age ≥ 45 years (aHR = 7.71, 95% CI: 1.72, 34.50), educational status (primary schooling, aHR = 3.54, 95% CI: 1.49, 8.40; secondary schooling, aHR = 2.75, 95% CI: 1.08, 7.03), lack of family support (aHR = 2.80, 95% CI: 1.27, 6.19), nutritional support (aHR = 3.40, 95% CI:1.68, 6.89), ≥ 10 km distance to travel to a health facility (aHR = 6.06, 95% CI: 2.33, 15.81) had significantly predicted LTFU from TB treatment and care. Conclusions LTFU from adult TB care and treatment was 12 times higher among those who travelled ≥10 km to reach a health facility compared to those who travelled less. To retain adult TB patients in care and ensure appropriate treatment, health professionals and other stakeholders should give due attention to the factors that drive LTFU. We suggest identifying concerns of older patients at admission and those who travel long distance and establish social support platforms that could help people to complete TB treatment.

Abstract
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.

Abstract
Differential diagnosis of tuberculosis (TB) and latent TB infection (LTBI) remains a public health priority in high TB burden countries. Pulmonary TB is diagnosed by sputum smear microscopy, chest X-rays, and PCR tests for distinct Mycobacterium tuberculosis (Mtb) genes. Clinical tests to diagnose LTBI rely on immune cell stimulation in blood plasma with TB-specific antigens followed by measurements of interferon-γ concentrations. The latter is an important cytokine for cellular immune responses against Mtb in infected lung tissues. Sputum smear microscopy and chest X-rays are not sufficiently sensitive while both PCR and interferon-γ release assays are expensive. Alternative biomarkers for the development of diagnostic tests to discern TB disease states are desirable. This study's objective was to discover sputum diagnostic biomarker candidates from the analysis of samples from 161 human subjects including TB patients, individuals with LTBI, negative community controls (NCC) from the province South Omo, a pastoral region in Ethiopia. We analyzed 16S rRNA gene-based bacterial taxonomies and proteomic profiles. The sputum microbiota did not reveal statistically significant differences in α-diversity comparing the cohorts. The genus Mycobacterium, representing Mtb, was only identified for the TB group which also featured reduced abundance of the genus Rothia in comparison with the LTBI and NCC groups. Rothia is a respiratory tract commensal and may be sensitive to the inflammatory milieu generated by infection with Mtb. Proteomic data supported innate immune responses against the pathogen in subjects with pulmonary TB. Ferritin, an iron storage protein released by damaged host cells, was markedly increased in abundance in TB sputum compared to the LTBI and NCC groups, along with the α-1-acid glycoproteins ORM1 and ORM2. These proteins are acute phase reactants and inhibit excessive neutrophil activation. Proteomic data highlight the effector roles of neutrophils in the anti-Mtb response which was not observed for LTBI cases. Less abundant in the sputum of the LTBI group, compared to the NCC group, were two immunomodulatory proteins, mitochondrial TSPO and the extracellular ribonuclease T2. If validated, these proteins are of interest as new biomarkers for diagnosis of LTBI.

Tuberculosis treatment outcome and associated factors among tuberculosis patients at Wolayta Sodo Teaching and Referral Hospital, Southern Ethiopia: a retrospective study. J Public Health Res 2021; 10. [PMID: 33882659 PMCID: PMC8419628 DOI: 10.4081/jphr.2021.2046] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 04/08/2021] [Indexed: 11/22/2022] Open
Abstract
Background: Tuberculosis is a major public health problem throughout the world particularly in resource limited countries. Measuring and reporting of TB treatment outcomes and identifying associated factors are fundamental part of TB treatment. The aim of this study was to assess TB treatment outcome and associated factors among TB patients in Wolayta Sodo Teaching and Referral Hospital, Southern Ethiopia. Design and Method: Facility based retrospective cohort study was conducted in Wolayta Sodo Teaching and Referral Hospital. All TB patients who registered during September 2014 to August 2019 and had known treatment outcome were included in the study. The data were collected using pretested structured data extraction format that included demographic, clinical and treatment outcome variables. SPSS Version 23 for windows was used for data processing. Bivariate and multivariate analysis with 95% confidence interval (CI) was employed to infer associations between the independent and dependent variables. Results: Of total 232 TB patients included in the study, 54.3% were male, 80.2% were urban residents, 65.9% were pulmonary TB (PTB). From the total 153 PTB cases, 31.5% were smear positive, 17.2% were HIV co-infected and all of them were on antiretroviral treatment. Most, 97.0% of the TB cases were newly diagnosed and all were treated as first line treatment category. The overall treatment success rate was 82.5% (28% cured 54.3% completed), 11.2% loss to follow-up, 4.7% dead and 0.9% treatment failure. The treatment success rate of HIV co-infected TB patients was 77.5%. There was no significant association between TB treatment outcome and age, sex, residence, type of TB, category of patients and HIV status. Conclusion: The treatment success rate was low (82.5%) which is below the 90% threshold defined standard with high proportion of patient’s lost to follow-up (11.2%). A higher number of transfer-out cases were recorded in this study. Thus, supervision and monitoring of DOTs implementation, improved counseling service, mechanisms for lost to follow-up patients should be strengthen. Establish efficient referral and contact tracing mechanisms for transferred-out cases and document their treatment outcomes of status is also fundamental. Significance for public health In Ethiopia, recognition and amendment of treatment outcome is not feasible with poor surveillance system as well as limited monitoring and evaluation of the health system. Accurate recording and reporting of TB treatment outcomes and associated factors is fundamental to facilitate the End TB Strategy set target TB treatment success rate 90% by 2025. Identifying and measure this information is important for health professionals, programmers and policymakers in terms of resource planning, prioritization and distribution.

Abstract
BACKGROUND Tuberculosis (TB) is one of the major public health problems in Ethiopia. Determining treatment outcome of TB cases could help to understand the effectiveness of TB control efforts. The objective of this study was to assess TB treatment outcome and associated factors and determine the risk factors of death among TB cases who were on Directly Observed Treatment Short course (DOTS). METHODOLOGY We analyzed a retrospective data for TB cases who were on DOTS at Dilla Referral Hospital from July 2011- June 2016. The study population was TB cases with known HIV status and whose treatment outcome was evaluated at the Hospital. Data were entered, cleaned and analyzed using statistical package SPSS for windows, version 20. RESULT Out of 899 registered TB cases, 731 included in this analysis. Of these cases, 424 (58.0%) were male and 334 (45.7%) were in the age group of below 25 years. Treatment success rate of TB was 675 (92.3%) and death rate was 18 (2.5%). Treatment outcome showed statistically significant variation by HIV status (P < 0.001). HIV status of the TB cases and pretreatment weight were associated with TB treatment outcome. HIV status of the TB cases was associated with death of the TB cases (Adjusted Odds Ratio (AOR) 5.0; CI 95%: 1.8-13.5). CONCLUSION TB treatment success rate found in this study was high. Patient's weight and HIV status were associated with treatment outcome. Moreover, HIV status predicted death of TB cases. Cautious treatment follow-up and defaulter tracing mechanisms for TB cases with these risk factors were suggested.

Olupot B, Adrawa N, Bajunirwe F, Izudi J. HIV infection modifies the relationship between distance to a health facility and treatment success rate for tuberculosis in rural eastern Uganda. J Clin Tuberc Other Mycobact Dis 2021; 23:100226. [PMID: 33732899 PMCID: PMC7944029 DOI: 10.1016/j.jctube.2021.100226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/07/2022] Open
Abstract
Distance from residence to a health facility presents a physical barrier. Our data show that long-distance is associated with a lower treatment success rate. Also, we found long-distance is insignificantly associated with high mortality. HIV modifies the effect of long-distance on mortality. People with tuberculosis who travel long distances need improved access to treatment.
Rationale Distance from residence to a health facility especially in rural areas presents a physical barrier and may influence tuberculosis (TB) treatment outcomes. Objectives We examined the association between distance from residence to a health facility and TB treatment outcomes namely treatment success rate (TSR) and mortality, and whether HIV influences this relationship among people with TB in Kumi district in rural eastern Uganda. Methods In this cross-sectional design, we abstracted data from TB unit registers across four large health facilities. Travel of ≥5 km to a health facility was considered a long distance. The primary outcome was TSR and the secondary was mortality. We performed a generalized linear model with Poisson distribution with a log-link and robust standard errors to determine the association between distance and the study outcomes adjusting for potential confounders. We report the adjusted risk ratio (aRR) and 95% confidence interval (CI). Measurement and results Of 611 participants studied, 484 (79.2%) were successfully treated, 18 (2.9%) died, and 359 (58.7%) travelled a long distance to access TB treatment. Long-distance was significantly associated with lower TSR (aRR, 0.93; 95% CI, 0.89–0.96). Further analysis showed that longer distance was associated with lower TSR among HIV positive persons with TB (aRR, 0.83; 95% CI, 0.72–0.96), but not among HIV negative persons with TB (aRR, 0.94; 95% CI, 0.85–1.03). Although it was not significant, longer distance showed a tendency towards worse mortality among HIV positive people with TB (aRR, 2.78; 95% CI, 0.80–9.66), but not among HIV negative people with HIV (aRR, 0.21; 0.03–1.74). Conclusions A majority of people with TB travel long distances to access treatment. Long distances are associated with lower TSR and higher mortality and affect people with TB who are HIV positive but not HIV negative. Interventions should focus on improving access to treatment for people with TB who travel long distances.

Abstract
BACKGROUND Tuberculosis (TB) is caused by Mycobacterium tuberculosis complex (MTBC). Mapping the genetic diversity of MTBC in high TB burden country like Ethiopia is important to understand principles of the disease transmission and to strengthen the regional TB control program. The aim of this study was to investigate the genetic diversity of Mycobacterium tuberculosis complex (MTBC) isolates circulating in the South Omo, southern Ethiopia. METHODS MTBC isolates (N = 156) were genetically analyzed using spacer oligotyping (spoligotyping) and mycobacterial interspersed repetitive unit-variable number of tandem repeat (MIRU-VNTR) typing. Major lineages and lineages were identified using MTBC databases. Logistic regression was used to correlate patient characteristics with strain clustering. RESULTS The study identified Euro-American (EA), East-African-Indian (EAI), Indo-Oceanic (IO), Lineage_7/Aethiops vertus, Mycobacterium bovis and Mycobacterium africanum major lineages in proportions of 67.3% (105/156), 22.4% (35/156), 6.4% (10/156), 1.9% (3/156), 1.3% (2/156) and 0.6% (1/156), respectively. Lineages identified were Delhi/CAS 23.9% (37/155), Ethiopia_2 20.6% (32/155), Haarlem 14.2% (22/155), URAL 14.2%(22/155), Ethiopia_3 8.4% (13/155), TUR 6.5% (10/155), Lineage_7/Aethiops vertus 1.9% (3/155), Bovis 1.3% (2/155), LAM 1.3% (2/155), EAI 0.6% (1/155), X 0.6% (1/155) and Ethiopia H37Rv-like strain 0.6% (1/155). Of the genotyped isolates 5.8% (9/155) remained unassigned. The recent transmission index (RTI) was 3.9%. Orphan strains compared to shared types (AOR: 0.09, 95% CI: 0.04-0.25) were associated with reduced odds of clustering. The dominant TB lineage in pastoral areas was EAI and in non-pastoral areas was EA. CONCLUSION The epidemiological data, highly diverse MTBC strains and a low RTI in South Omo, provide information contributing to the TB Control Program of the country.

Abstract
BACKGROUND Ethiopia has shown significant efforts to address the burden of TB/HIV comorbidity through the TB/HIV collaborative program. However, these diseases are still the highest cause of death in the country. Therefore, this systematic review and meta-analysis evaluated this program by investigating the overall proportion of unknown HIV status among TB patients using published studies in Ethiopia. METHODS We conducted a systematic review and meta-analysis of published studies in Ethiopia. We identified the original studies using the databases MEDLINE/PubMed, and Google Scholar. The heterogeneity across studies was assessed using Cochran's Q test and I 2 statistics. The Begg's rank correlation and the Egger weighted regression tests were assessed for the publication bias. We estimated the pooled proportion of unknown HIV status among TB patients using the random-effects model. RESULTS Overall, we included 47 studies with 347,896 TB patients eligible for HIV test. The pooled proportion of unknown HIV status among TB patients was 27%(95% CI; 21-34%) and with a substantial heterogeneity (I2 = 99.9%). In the subgroup analysis, the pooled proportion of unknown HIV status was 39% (95% CI; 25-54%) among children and 20% (95% CI; 11-30%) among adults. In the region based analysis, the highest pooled proportion of unknown HIV status was in Gambella, 38% (95% CI; 16-60%) followed by Addis Ababa, 34%(95% CI; 12-55%), Amhara,30%(95% CI; 21-40%),and Oromia, 23%(95% CI; 9-38%). Regarding the study facilities, the pooled proportion of unknown HIV status was 33% (95% CI; 23-43%) in the health centers and 26%(95% CI; 17-35%) in the hospitals. We could not identify the high heterogeneity observed in this review and readers should interpret the results of the pooled proportion analysis with caution. CONCLUSION In Ethiopia, about one-third of tuberculosis patients had unknown HIV status. This showed a gap to achieve the currently implemented 90-90-90 HIV/AIDS strategic plan in Ethiopia, by 2020. Therefore, Ethiopia should strengthen TB/HIV collaborative activities to mitigate the double burden of diseases.

Abstract
Background Tuberculosis (TB) is a leading cause of death among infectious agents, ranking above HIV/AIDS. Though much effort has been done, Ethiopia remained one of those countries which share the greatest burden of TB. Evaluating the TB treatment outcome is one method of TB control measures. Therefore, the aim of the current study was to assess TB treatment outcome and its determinants under directly observed treatment short courses in Adama City, Central Ethiopia. Method An institutional based cross sectional study was conducted in all public and private health facilities of Adama city from March 1st 2016 to December 31st, 2016. The data were entered and analyzed by using SPSS version 21.0 statistical software. The results were presented using descriptive statistics. Univariate and multivariate logistic regression model was used to evaluate the potential determinants of unsuccessful treatment outcome. Results Among 281 patients evaluated, 90(32%) were cured, 137(48.8%) have completed the treatment, 4(1.4%) were treatment failure, 36(12.8%) were lost to follow up, and 14 (5%) died. The overall treatment success rate was 80.8%. Age 15–24 (Adjusted odds ratio (AOR): 4.97; 95% Confidence interval (CI): 1.13–21.90), distance less than 5 kilometers from treatment center (AOR: 3.1; 95% CI: 1.42–6.77), being seronegative for human immunodeficiency virus (HIV) (AOR: 20.38; 95% CI: 7.80–53.24) were associated with successful TB treatment outcome. Conclusion The treatment outcome of all forms tuberculosis patients in Adama city was unsatisfactory when referred with the national pooled estimate of 86% and WHO 2030 international target of ≥90%. Thus, enhancing client supervision, treatment monitoring; and working on provision TB treatment services at nearby health facilities should be a priority concern to improve the success rate of treatment outcome. Further studies are also recommended to explore important factors which were not examined by current study.

Abstract
Background Despite the availability of effective drugs, tuberculosis remains a major public health problem that predominantly affects low- and middle-income countries. This study aimed to assess tuberculosis treatment outcomes among patients treated at one of the primary health care levels in Addis Ababa, Ethiopia. Methods An institutional-based retrospective cross-sectional study was conducted at a tuberculosis clinic in public primary healthcare facility. The study populations were all patients with tuberculosis who had been completed their treatment course in the center from July 2014 to July 2018. After getting Ethical clearance and permission from the health center, trained data collectors working in the center were recruited. The collected data were checked for completeness every day by the principal investigators. Data were edited, cleaned, and analyzed using SPSS version 25. Descriptive statistics were used to summarize the data while multinomial logistic regression was employed to explore associations among variables of interest, and p < 0.05 was considered as statistically significant. Results A total of 352 patients with tuberculosis were included for the study with a median age of 25 years which ranged from 1 to79 year. Most (36.4%) participants were in the age group of 15 to 24 years. The majority (38.8%) of patients had extrapulmonary tuberculosis, 11.9% of them were HIV positive and only two had family history of tuberculosis. Regarding treatment outcome, 238(67.6%) completed the treatment, 95(27%) cured and the rest were unsuccessful treatment outcomes 19(5.4%) either died, defaulted or treatment failed. The odds ratio for cured in relation to unsuccessful treatment outcome was found to be significantly higher in HIV negative patients (AOR = 6.1; 95%CI 2.1–13.9) compared with those patients tested positive for HIV. While patients with smear-positive pulmonary tuberculosis (AOR = 10.5, 95% CI 5.36–16.31) were significantly associated with the odds of having complete treatment cure as compared to patients with extrapulmonary tuberculosis. Similarly being HIV positive and extrapulmonary tuberculosis were predicting factors for unsuccessful treatment compared with their counterparts. Conclusions The finding of the present study showed that successful tuberculosis treatment outcome was found to be optimal.

Abstract
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.

Abstract
OBJECTIVES To summarise treatment success rate (TSR) among adult bacteriologically confirmed pulmonary tuberculosis (BC-PTB) patients in sub-Saharan Africa (SSA). DESIGN We searched MEDLINE, EMBASE, Google Scholar and Web of Science electronic databases for eligible studies published in the decade between 1 July 2008 and 30 June 2018. Two independent reviewers extracted data and disagreements were resolved by consensus with a third reviewer. We used random-effects model to pool TSR in Stata V.15, and presented results in a forest plot with 95% CIs and predictive intervals. We assessed heterogeneity with Cochrane's (Q) test and quantified with I-squared values. We checked publication bias with funnel plots and Egger's test. We performed subgroup, meta-regression, sensitivity and cumulative meta-analyses. SETTING SSA. PARTICIPANTS Adults 15 years and older, new and retreatment BC-PTB patients. OUTCOMES TSR measured as the proportion of smear-positive TB cases registered under directly observed therapy in a given year that successfully completed treatment, either with bacteriologic evidence of success (cured) or without (treatment completed). RESULTS 31 studies (2 cross-sectional, 1 case-control, 17 retrospective cohort, 6 prospective cohort and 5 randomised controlled trials) involving 18 194 participants were meta-analysed. 28 of the studies had good quality data. Egger's test indicated no publication bias, rather small study effect. The pooled TSR was 76.2% (95% CI 72.5% to 79.8%; 95% prediction interval, 50.0% to 90.0%, I2 statistics=96.9%). No single study influenced the meta-analytical results or conclusions. Between 2008 and 2018, a gradual but steady decline in TSR occurred in SSA but without statistically significant time trend variation (p=0.444). The optimum TSR of 90% was not achieved. CONCLUSION Over the past decade, TSR was heterogeneous and suboptimal in SSA, suggesting context and country-specific strategies are needed to end the TB epidemic.

Abstract
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.

Abstract
Background Knowledge of drug-sensitivity patterns of Mycobacterium tuberculosis complex (MTBC) strains isolated from patients is an important aspect of TB control strategy. This study was conducted to evaluate the drug sensitivity of MTBC isolates in South Omo, southern Ethiopia. Materials and methods A total of 161 MTBC isolates (153 from new cases and eight re-treatment TB cases) were isolated using Lowenstein Jensen medium of which 126 isolates were able to be tested for drug sensitivity by BACTEC™MGIT™ 960 system, while all the 161 isolates were tested by GenoType® MTBDRplus VER 2.0. Descriptive statistics and logistic regression were used to express and present results. Results On the basis of MGIT 960 system, the prevalence of mono-resistance was 9.2% (11/119) in the new cases, although neither poly-resistance nor multidrug resistance (MDR) was recorded in these cases. On the basis of GenoType MTBDRplus assay, two of the 153 isolates (1.3%) of the new cases were mono-resistant for rifampicin (RIF) and one of these isolates had known rpoB gene mutation (H526D). One of the eight (12.5%) isolates obtained from the re-treatment cases was MDR with rpoB gene mutation (D516V) and katG gene mutation (S315T2). Taking MGIT 960 system as a gold standard, the sensitivities of the MTBDRplus assay were 33.3%, 100% and 100% for detection of resistance to isoniazid, RIF and MDR, respectively. On the other hand, its specificities were 99.2%, 100% and 100% for detection of resistance to RIF, isoniazid and MDR, respectively. Conclusion The magnitude of drug resistance was relatively low in the new TB cases of South Omo as compared to the reports from the other regions of the country. This is encouraging and hence the TB Control Program in the Zone should strengthen its program so that the emergence of drug resistance is inhibited.
