Trop Med Infect Dis 2024; 9:119. [PMID: 38787052 PMCID: PMC11125710 DOI: 10.3390/tropicalmed9050119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 05/04/2024] [Accepted: 05/14/2024] [Indexed: 05/25/2024] Open
Abstract
Background: Guizhou Province in Southwest China has experimented with a centralized hospitalization (CH) treatment for active and severe cases of pulmonary tuberculosis (PTB). The objective of this study was to compare treatment outcomes of patients with tuberculosis (TB) receiving care in a CH setting with those receiving home-based (HB) care. In addition, this study aimed to assess the probability of their household contacts contracting tuberculosis infection. Method: A retrospective review of medical records was undertaken for patients with TB who completed their treatment in four counties in Guizhou, China, spanning from January 2022 to August 2023. In addition, a cross-sectional survey was conducted on the tuberculin skin test (TST) among household contacts of new patients with TB who had completed their treatment. Results: In the retrospective study, 94.8% had successful CH treatment, and 93.1% had successful HB treatment (p value = 0.70). In the prospective study, 559 and 448 household contacts of patients receiving CH treatment had 16 positive and 89 negative TST results, whereas those with HB treatment showed 26 positive and 74 negative TST results. Regarding a logistic regression analysis, the CH group was nearly two times more likely to test negative on the TST, 1.95 (95% CI: 0.98, 3.92). After adjusting for confounding variables, the odds ratio increased significantly to 4.42 (95% CI: 1.22, 16.04). Conclusions: CH for treatment of TB did not show superior success rates, but it may reduce the risk of transmitting tuberculosis infection to household contacts compared to home treatment.

Medicine (Baltimore) 2024; 103:e38034. [PMID: 38701249 PMCID: PMC11062662 DOI: 10.1097/md.0000000000038034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Accepted: 04/05/2024] [Indexed: 05/05/2024] Open
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 Public health problems related to tuberculosis (TB) remain substantial globally, particularly in resource-limited countries. Determining TB treatment outcomes and identifying contributing factors are the basic components of the TB control strategy. In Ethiopia, different studies have been done on treatment outcomes and multiple associated factors, and there is also a little information on the effect of nutritional status on TB treatment outcomes. So there is a need for comprehensive research that examines the combined effects of multiple factors along with nutritional status. METHODS A five-year institution-based retrospective cross-sectional study was conducted at Mizan Tepi University Teaching Hospital, South West Ethiopia. This study included all tuberculosis patients who were documented in the TB registration and had known treatment outcomes at the treatment facility between January 1, 2016, and December 31, 2020. Data was collected through a pretested structured data extraction checklist. Data were entered into Epidata version 3.1 and analyzed through SPSS version 22. Multiple logistic regression was employed to assess the association between dependent and independent variables. A p-value of less than 0.05 was considered statistically significant. RESULT Of the total 625 TB patients, 283 (45.3%), 175 (28%), and 167 (26.7%) had smear-positive, extra-pulmonary, and smear-negative tuberculosis, respectively. The majority of study participants had normal weight (62.2%), were in the age group of 15-44 (67.4%), were new cases (73.8%), and were from urban areas (69.4%). About 32.2% of cases were HIV-positive. The overall unsuccessful treatment rate was 25%. From the total unsuccessful treatment rates, the highest proportion was a death rate of 90 (14.4%), followed by a treatment failure of 56 (9%). Being female (AOR = 1.7, 95% CI: 1.2-2.5), HIV positive (AOR = 2.7, 95% CI: 1.9-4.1), undernutrition (BMI<18.5kg/m2) (AOR = 1.9, 95% CI: 1.3-2.9), and smear-negative pulmonary TB (AOR = 1.6, 95% CI: 1-2.5) were independent predictors of unsuccessful treatment outcomes. CONCLUSION The treatment success rate in the study area is very poor. Poor treatment outcomes were associated with undernutrition, female gender, HIV positivity and smear-negative pulmonary TB. So, continuous and serious supervision and monitoring of directly observed treatment short course (DOTS) program accomplishment, early detection of HIV and TB, prompt anti TB and antiretroviral treatment initiation and adherence, enhanced nutritional assessment, and counseling services need to be strengthened to improve treatment outcomes.

Abstract
BACKGROUND Tuberculosis (TB) remains a global public health issue, impacting millions of people worldwide. This study determined the outcomes of TB treatment managed within a 10 year period at the Bamenda Regional Hospital in Cameroon. METHODS A retrospective study was carried out among 2428 patients diagnosed and treated for active TB infection from 2013 to 2022, at the Bamenda Regional Hospital. Data collection was done from March to April 2023 using a data extraction form. Bivariate and multivariate logistic regression models were used to identify factors associated with successful TB treatment outcomes. Data was analyzed using SPSS software version 26. RESULTS Of the 2428 patients with TB, 1380 (56.8%) were cured, 739 (30.4%) completed treatment, treatment failures were recorded in 10 (0.4%) patients, and 200 (8.2%) died during or after receiving treatment. Treatment default was the outcome in 99 (4.1%). Successful treatment outcomes were reported in 2119 (87.3%). Patients within age groups 41-50 (P = 0.010), 51-60 (P = 0.041), and >60 years (P = 0.006), male (P = 0.004), and human immunodeficiency virus-positive patients (P < 0.001) had decreased odds of successful treatment outcomes. CONCLUSION The outcomes of treatment within a 10 year period showed that the treatment success was 2.7% below the World Health Organizations target. Prioritizing vulnerable patient groups in TB management and implementing public health interventions such as financial assistance and nutritional support will go a long way in improving treatment outcomes.

Abstract
An essential metric for determining the efficacy of tuberculosis (TB) control programs is the evaluation of TB treatment outcomes; this study was conducted to investigate treatment outcomes and associated factors among tuberculosis patients in rural areas of Eastern Cape, South Africa. Assessing treatment outcomes is fundamental to facilitating the End TB Strategy's set target. Clinic records from 457 patients with DR-TB were examined for data collection while 101 patients were followed up prospectively. Data were analyzed using Stata version 17.0. The odds ratio and 95% confidence interval were calculated to check the association between variables. p ≤ 0.05 was considered statistically significant. Of the 427 participants, 65.8% had successful treatment whilst 34.2% had unsuccessful TB treatment. A total of 61.2% and 39% of the HIV-positive and HIV-negative participants had a successful TB treatment whilst 66% and 34% of both HIV-negative and positive participants had unsuccessful TB treatment. From the 101 patients that were followed up, smokers took longer to have treatment outcomes compared to non-smokers. In the study with HIV/TB co-infection, men predominated. HIV and tuberculosis co-infection made therapy difficult with unfavorable effects on TB management. The treatment success rate (65.8%) was lower than the WHO threshold standard with a high proportion of patients being lost to the follow up. The co-infection of tuberculosis and HIV resulted in undesirable treatment outcomes. Strengthening TB surveillance and control is recommended.

Abstract
Background Despite reported tuberculosis (TB) treatment success rate of 86%, TB remains a leading cause of death in Ethiopia. We investigated patient and provider-specific factors associated with unfavorable treatment outcomes in Ethiopian health facilities providing TB care. Methods Data on characteristics and treatment outcomes of patients registered for TB treatment at 15 public health facilities (4 hospitals and 11 health centres) were collected from clinic registers. Proportions of unfavorable outcomes (defined as deaths, loss-to-follow-up [LTFU] and treatment failure), were compared across facilities using multivariable logistic regression, with separate analyses for death and LTFU. Results Among 3359 patients (53.5 % male, median age 28 years, 19.6 % HIV-positive), 296 (8.8 %) had unfavorable treatment outcome. Proportions of unfavorable outcomes across facilities ranged from 2.0 % to 21.1 % (median 8.3 %). Median proportions of death and LTFU among facilities were 3.3 % (range 0-10.9 %) and 2.6 % (range 0.6 %-19.2 %), respectively. Three facilities had significantly higher rates of LTFU, whereas two facilities had higher rates of death. The two facilities with full-time TB-nurses had higher proportions of successful outcomes (95.2 % vs 90.1 %, adjusted odds ratio 2.27, p < 0.0001). Conclusion Substantial variability of TB treatment outcomes was observed across the assessed health facilities providing TB care, independently of age and HIV co-infection, reflecting possible differences in service structure and related quality of care.

Tuberculosis Treatment Outcomes and Its Predictors among Tuberculosis Patients Registered at Tefera Hailu Memorial General Hospital, Sekota Town, Northeast Ethiopia: A Seven-Year Retrospective Study. THE CANADIAN JOURNAL OF INFECTIOUS DISEASES & MEDICAL MICROBIOLOGY = JOURNAL CANADIEN DES MALADIES INFECTIEUSES ET DE LA MICROBIOLOGIE MEDICALE 2023; 2023:4212312. [PMID: 36923155 PMCID: PMC10010884 DOI: 10.1155/2023/4212312] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 02/25/2023] [Accepted: 02/28/2023] [Indexed: 03/08/2023]
Abstract
Background Despite the availability of effective medications, tuberculosis (TB) continues to be a serious global public health problem, primarily affecting low and middle-income nations. Measuring and reporting TB treatment outcomes and identifying associated factors are fundamental parts of TB treatment. The goal of this study was to look at the outcomes of TB treatment and the factors that influence them in Sekota, Northeast Ethiopia. Materials and Methods A facility-based retrospective study was conducted in Tefera Hailu Memorial General Hospital, Sekota town, Northeast Ethiopia. All TB patients who registered in the TB log book and had known treatment outcomes at the treatment center between January 1, 2015, and December 30, 2021, were included in this study. The data was gathered utilizing a pretested structured data extraction format that comprised demographic, clinical, and treatment outcome characteristics. Data were entered, cleaned, and analyzed using SPSS version 25. Descriptive statistics and logistic regression analysis were employed. A p value of less than 0.05 was considered statistically significant. Results A total of 552 registered TB patients' data were reviewed. Of these, 49.6% were male, 94.4% were new cases, 64.9% were presented with pulmonary TB, and 18.3% were HIV positive. Regarding the treatment outcome, 11.6% were cured, 82.2% completed their treatment, 1.1% had failed treatment, 1.3% were lost to follow-up, and the remaining 3.8% died during the follow-up. The overall treatment success rate among TB patients was 93.8%. The maximum number of successful treatment outcomes was 94.9% in 2021, while the lowest was 86.7% in 2020. The pattern of successful treatment results changes with the number of years of treatment. In the current study, being a new TB patient (AOR = 1.75, 95% CI: 1.31-7.32) and being an HIV-negative patient (AOR = 2.64, 95% CI: 1.20-5.8) were factors independently associated with a successful treatment outcome. Conclusion The rate of successful TB treatment outcomes in the current study was satisfactory. This achievement should be maintained and enhanced further by developing effective monitoring systems and educating patients about medication adherence.

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.

Abstract
Background Despite the available treatment options, pulmonary tuberculosis (TB) remains a leading cause of disease-related deaths worldwide. Treatment non-adherence/lost to follow-up (LTFU), particularly in developing countries, is a continuous concern. LTFU prolongs TB infectiousness and contributes to TB treatment failure, relapse, and death. Furthermore, LTFU also delays global TB eradication by promoting TB spread and drug-resistant TB strain development.[1] The purpose of this paper is to give an overview of the commonly observed risk factors associated with TB treatment LTFU in developing countries. Materials and Methods A literature survey was done of studies published in the past decade, which evaluated the risk factors for LTFU in TB patients, specifically in developing countries. Furthermore, some prospective TB treatment adherence initiatives and the feasibility of these initiatives within developing countries were assessed.[3]. Results Several variables, including socio-demographic, patient-related, TB disease and other health-related-factors, healthcare and system determinants, as well as treatment-related factors, were identified to increase the risk of TB treatment LTFU. More recently applied adherence interventions in developing countries, show potential for implementation on a larger scale. Conclusion Successful TB treatment is contingent on treatment adherence, and by addressing these persisting LTFU risk factors, treatment adherence in developing countries may be improved.

[PMID: 36591001 PMCID: PMC9789780 DOI: 10.11604/pamj.2022.43.78.31929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 03/13/2022] [Indexed: 11/07/2022] Open
Abstract
Introduction multi-drug resistance tuberculosis (MDR-TB) is associated with an increased risk of mortality among patients on treatment. Ethiopia is the countries with the high MDR-TB burden. This study aimed to determine the extent of mortality and associated factors among MDR-TB patients on treatment in eastern Ethiopia. Methods all completely documented data from June 2014 to January 2017 on MDR-TB patients were extracted from patients´ records, between December 2016 and January 2017, in Dader and Dire Dawa MDR treatment follow-up centers. Sociodemographic characteristics, clinical characteristics of MDR-TB patients, and treatment outcomes were extracted from the patients' records. Descriptive statistical methods were used to characterize the sociodemographic variables and the extent of mortality. Binary and multivariable logistic regression analyses were performed to assess factors associated with mortality using an adjusted odds ratio (AOR) at 95% confidence interval (CI). Statistical significance was considered at a P-value of less than 0.05. Results among 150 MDR-TB patients, 60.7% of them were males and their mean age was 30.34 + 1.06 years. In this study, the overall mortality rate was 11.3% (95% CI= 6.74-17.52). Previous history of ant-TB treatment (AOR=6.7, 95% CI: 1.59 - 17.15, P= 0.019), hospitalization (AOR=19.55, 95% CI: 6.23-43.37, P=0.001), and human immunodeficiency virus (HIV) coinfection (AOR=6.3, 95% CI: 2.98- 14.0, P= 0.008) were significantly associated with this mortality. Conclusion considerably high rate of mortality among MDR-TB patients on treatment highlights the need for more efforts in TB treatment and monitoring the program to limit mortality among MDR-TB patients in the study settings.

Abstract
Background Eritrea has achieved the global target (90%) for tuberculosis (TB) treatment success rate. Though, events of unsuccessful TB treatment outcomes (death, treatment failure, lost to follow up and not evaluated) could lead to further TB transmission and the development of resistant strains. Hence, factors related to these events should be explored and addressed. This study aims to fill the gap in evidence by identifying the determinants of unsuccessful TB treatment outcomes in Eritrea’s Northern Red Sea region. Methods A retrospective cohort study was conducted in Eritrea’s Northern Red Sea region. Data collected using a data extraction tool was analyzed using Stata version 13. Frequencies, proportions, median and standard deviations were used to describe the data. Furthermore, univariable and multivariable logistic regression analysis were performed to determine the risk factors for unsuccessful TB treatment outcomes. Crude odds ratio (COR) and adjusted odds ratio (AOR) with their 95% confidence interval (CI) presented and p-value < 0.05 was considered statistically significant. Results Among 1227 TB patients included in this study, 9.6% had unsuccessful TB treatment outcomes. In multivariable logistic regression analysis, TB cases 55–64 years old (AOR: 2.75[CI: 1.21–6.32], p = 0.016) and those ≥ 65 years old (AOR: 4.02[CI: 1.72–9.45], p = 0.001) had 2.7 and 4 times higher likelihood of unsuccessful TB treatment outcome respectively. In addition, HIV positive TB patients (AOR: 5.13[CI: 1.87–14.06], p = 0.002) were 5 times more likely to have unsuccessful TB treatment outcome. TB treatment in Ghindae Regional Referral Hospital (AOR: 5.01[2.61–9.61], p < 0.001), Massawa Hospital (AOR: 4.35[2.28–8.30], p< 0.001) and Nakfa Hospital (AOR: 2.53[1.15–5.53], p = 0.021) was associated with 5, 4 and 2.5 higher odds of unsuccessful TB treatment outcome respectively. Conclusion In this setting, old age, HIV co-infection and health facility were the independent predictors of unsuccessful TB treatment outcome.

Drug-susceptible tuberculosis treatment outcomes and its associated factors among inmates in prison settings in Bauchi State, Nigeria, 2014–2018. PLoS One 2022; 17:e0270819. [PMID: 35789216 PMCID: PMC9255776 DOI: 10.1371/journal.pone.0270819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 06/20/2022] [Indexed: 11/18/2022] Open
Abstract
Tuberculosis (TB) is a contagious disease and its transmissibility is increased in congregate settings. TB incidence rates are five-to-fifty times higher among inmates in prison settings than the general population which has a direct impact on the outcome of TB treatment. There is paucity of information on TB treatment outcomes and its associated factors in Nigerian prison settings. We therefore assessed TB treatment outcomes among inmates in prison settings in Bauchi State, Nigeria. We conducted a retrospective data analysis of inmates with TB in the five-main prison settings in Bauchi State. We extracted socio-demographic, clinical and treatment outcome characteristics from TB treatment register of inmates treated for TB between January 2014 and December 2018, using a checklist. We calculated the TB treatment success rate (TSR) and explored the relationship between the TSR and socio-demographic and clinical characteristics. Related variables were modelled in multiple logistic regression to identify factors associated with TSR at 5% level of significance. All 216 inmates were male with mean (SD) age of 37.6±11.4 years. Seventy-six (35.2%) were cured, 61 (28.2%) completed treatment, 65 (30.1%) were transferred-out without evaluation and 14 (6.5%) died. Overall TSR was 72.9%. Factors associated with successful-treatment-outcome were age, weight, imprisonment duration and HIV status. The results indicate that inmates who are 20–29 years are at least ten times more likely to be successful (aOR = 10.5; 95%CI: 3.2–35.1) than inmates who are 55 years or older. Inmates who are 30–39 years are about four times more likely to be successful than inmates who are 55 years or older (aOR = 4.2; 95% CI: 1.3–13.1). In general, the younger an inmate, the more successful he is. Inmates with pretreatment-weight; 55kg or more are 13 times more likely to be successful (aOR = 13.3; 95%CI: 6.0–29.6) than inmates with weight below 55kg. Inmates who were imprisoned for 2 years or less are about three times more likely to be successful (aOR = 2.6; 95%CI: 1.3–5.4) than inmates who were imprisoned for more than 2 years and HIV negative inmates were three times more likely to succeed (aOR = 3.3; 95%CI:1.4–7.8) than inmates who were HIV positive. We recommended that to improve TB treatment outcome among inmates; age, duration-of-imprisonment, weight and TB/HIV co-infection should be the major consideration during pretreatment, psychological and nutritional counselling and a tracking-system be developed by the authority to follow-up inmates transferred-out to other health facilities to ensure they complete the treatment and outcomes evaluated.

Abstract
Tuberculosis (TB) remains a major medical and public health problem throughout the world, especially in developing countries including Ethiopia. Its control program is currently being challenged by the spread of drug-resistant TB, which is the result of poor treatment outcomes. Hence, this study assessed poor adult TB treatment outcomes and associated factors in Gibe Woreda, Southern Ethiopia. An institution-based cross-sectional study was conducted from March 1, 2020 to March 30, 2020, using a standard checklist to review clinical charts of TB patients who enrolled on first-line TB treatment under DOTS between June 2016 and June 2019. Poor treatment outcomes constituted death during treatment, treatment failure, and loss to follow-up (LTFU). Descriptive statistics were used to describe the characteristics of study participants. A binary logistic regression model was fitted to identify factors influencing treatment outcome and adjusted odds ratios with a 95% confidence interval were reported. The statistical significance of all tests in this study was declared at P-value <5%. A total of 400 adult TB patients were participated. The mean age of study participants was 39.2±16.7 years, 55.5% were males and 79.8% were pulmonary tuberculosis cases. Regarding the treatment outcomes, 58% completed treatment, 27.5% cured, 9.3% were LTFU, 3.2% died, and 2.0% failed. The overall poor treatment outcome was 14.5% (95% CI: 11.1-17.9). Age (aOR = 1.02; 95%CI: 1.01-1.04), male gender (aOR = 1.82; 95% CI: 0.99-3.73), travel ≥ 10 kilometres to receive TB treatment (aOR = 6.55; 95% CI: 3.02-14.19), and lack of family support during the course of treatment (aOR = 3.03; 95% CI: 1.37-6.70), and bedridden baseline functional status (aOR = 4.40; 95% CI: 0.96-20.06) were factors associated with poor treatment outcome. Successful TB treatment outcome in this study area was below the national TB treatment success rate. To improve positive treatment outcomes, remote areas should be prioritized for TB interventions, and stakeholders in TB treatment and care should give special emphasis to adults over the age of 45 years, males, those who travel more than 10 kilometres to receive TB care, having bedridden baseline functional status and those who had no family support.

Abstract
Background Tuberculosis (TB) is one of the leading causes of deaths in Africa, monitoring its treatment outcome is essential to evaluate treatment effectiveness. The study aimed to evaluate proportion of poor TB treatment outcomes (PTO) and its determinants during six-months of treatment at Kilifi County, Kenya. Methods We conducted a retrospective analysis of data from the TB surveillance system (TIBU) in Kilifi County, Kenya from 2012 to 2019. The outcome of interest was PTO (lost-to-follow-up (LTFU), death, transferred out, treatment failure, drug resistance) or successful treatment (cured or completed treatment). We performed time-stratified (at three months follow-up) survival regression analyses accounting for sub-county heterogeneity to determine factors associated with PTO. Results We included 14,706 TB patients, their median (IQR) age was 37
(28–50) years and 8,791 (60%) were males. A total of 13,389 (91%) were on first line anti-TB treatment (2RHZE/4RH), 4,242 (29%) were HIV infected and 192 (1.3%) had other underlying medical conditions. During 78,882 person-months of follow-up, 2,408 (16%) patients had PTO: 1,074 (7.3%) deaths, 776 (5.3%) LTFU, 415 (2.8%) transferred out, 103 (0.7%) treatment failure and 30 (0.2%) multidrug resistance. The proportion of poor outcome increased from 7.9% in 2012 peaking at 2018 (22.8%) and slightly declining to 20% in 2019 (trend test P = 0.03). Over two-thirds 1,734 (72%) poor outcomes occurred within first three months of follow-up. In the first three months of TB treatment, overweight ((aHR 0.85 (95%CI 0.73–0.98), HIV infected not on ARVS (aHR 1.72 (95% CI 1.28–2.30)) and year of starting treatment were associated with PTO. However, in the last three months of treatment, elderly age ≥50 years (aHR 1.26 (95%CI 1.02–1.55), a retreatment patient (aHR 1.57 (95%CI 1.28–1.93), HIV infected not on ARVs (aHR 2.56 (95%CI 1.39–4.72), other underlying medical conditions (aHR 2.24 (95%CI 1.41–3.54)) and year of starting treatment were positively associated with PTO while being a female (aHR 0.83 (95%CI 0.70–0.97)) was negatively associated with PTO. Conclusions Over two-thirds of poor outcomes occur in the first three months of TB treatment, therefore greater efforts are needed during this phase. Interventions targeting HIV infected and other underlying medical conditions, the elderly and retreated patients provide an opportunity to improve TB treatment outcome.

Abstract
The spread of drug-resistant tuberculosis (DR TB) poses significant challenges to the control and successful eradication of TB globally. The current retrospective study was designed to evaluate the treatment outcomes and identify the risk factors associated with unsuccessful outcomes among DR TB patients. A total of 277/308 eligible DR TB patients were enrolled for treatment at the programmatic management unit of DR TB at the Pakistan Institute of Medical Sciences, Islamabad between January 2014 and July 2019. Treatment outcomes were defined according to the WHO recommendations. Death, treatment failure, and lost to follow-up (LTFU) were collectively grouped as unsuccessful treatment outcomes, whereas cured and treatment completed were summed up together as successful treatment outcomes. Out of the total 277 patients, 265 (95.67%) were multidrug/rifampicin-resistant TB (MDR/RR-TB) cases, 8 (2.89%) were isoniazid resistant cases, and 4 (1.44%) were extensively drug-resistant ones. In the current cohort, a total of 177 (63.9%) achieved successful treatment outcomes. Among them, 153 (55.2%) were declared cured and 24 (8.7%) completed their treatment. Of the remaining 100 (36.1%) patients with unsuccessful outcomes, 60 (21.7%) died, 32 (11.5%) were LTFU, and 8 (2.9%) had failed treatment. The proportion of male patients was relatively higher (55.2%), within the age group of 21–40 years (47.3%) and lived in rural areas (66.8%). The multivariate analysis revealed that unsuccessful outcomes had a statistically significant association with being male (adjusted odds ratio, AOR: 1.92, 95% confidence interval (CI): 1.10–3.36), being in an age group above 60 years (AOR: 3.34, 95% CI: 1.09–10.1), suffering from any comorbidity (AOR: 2.69, 95% CI: 1.35–5.38), and the history of use of second-line drugs (AOR; 3.51, 95% CI 1.35–9.12). In conclusion, treatment outcomes among DR TB patients at the study site were poor and did not achieve the treatment success target (≥75%) set by the World Health Organization.

Abstract
This review aimed to summarize and estimate the TB treatment success rate and factors associated with unsuccessful TB treatment outcomes in Africa. Potentially eligible primary studies were retrieved from PubMed and Google Scholar. The risk of bias and quality of studies was assessed using The Joanna Briggs Institute's (JBI) appraisal criteria, while heterogeneity across studies was assessed using Cochran's Q test and I2 statistic. Publication bias was checked using the funnel plot and egger's test. The protocol was registered in PROSPERO, numbered CRD42019136986. A total of 26 eligible studies were considered. The overall pooled estimate of TB treatment success rate was found to be 79.0% (95% CI: 76-82%), ranging from 53% (95% CI: 47-58%) in Nigeria to 92% (95% CI: 90-93%) in Ethiopia. The majority of unsuccessful outcomes were attributed to 48% (95% CI: 40-57%) death and 47% (95% CI: 39-55%) of defaulter rate. HIV co-infection and retreatment were significantly associated with an increased risk of unsuccessful treatment outcomes compared to HIV negative and newly diagnosed TB patients with RR of 1.53 (95% CI: 1.36-1.71) and 1.48 (95% CI: 1.14-1.94), respectively. TB treatment success rate was 79% below the WHO defined threshold of 85% with significant variation across countries. Countries need to explore contextual underlining factors and more effort is required in providing TB preventive treatment, improve case screening and linkage for TB treatment among HIV high-risk groups and use confirmatory TB diagnostic modality. Countries in Africa need to strengthen counseling and follow-up, socio-economic support for patients at high risk of loss to follow-up and poor treatment success is also crucial for successful TB control programs.

Abstract
BACKGROUND Since 2016, patients with rifampicin-susceptible tuberculosis (TB) have been treated with the 6-month first-line regimen, regardless of treatment history. We assessed treatment outcomes of previously treated and new patients in Machakos subcounty, Kenya. METHODS We performed a retrospective cohort study in patients started on first-line treatment between 2016 and 2017. Firth's logistic regression was used to estimate the effect of previous treatment on having a programmatic adverse outcome (either lost to follow-up, death, failure) and treatment failure vs treatment success (either cure or completion). RESULTS Of 1024 new and 79 previously treated patients, 88.1% and 74.7% were treated successfully, 6.5% and 7.6% died, 4.2% and 10.1% were lost to follow-up and 1.2% and 7.6% had treatment failure, respectively. Previous treatment predicted having a programmatic adverse outcome (adjusted odds ratio [aOR] 2.4 [95% confidence interval {CI} 1.4 to 4.2]) and treatment failure (aOR 7.3 [95% CI 2.6 to 20.4]) but not mortality. Similar correlations were found in 334 new and previously treated patients with confirmed baseline rifampicin susceptibility. CONCLUSION Previously treated patients were more at risk of experiencing a poor treatment outcome, mainly lost to follow-up and treatment failure. Adherence support may reduce lost to follow-up. Rifampicin drug susceptibility testing coverage should increase. More robust retreatment regimens may reduce treatment failure.

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.

Gautam N, Karki RR, Khanam R. Knowledge on tuberculosis and utilization of DOTS service by tuberculosis patients in Lalitpur District, Nepal. PLoS One 2021; 16:e0245686. [PMID: 33493188 PMCID: PMC7833137 DOI: 10.1371/journal.pone.0245686] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Accepted: 01/05/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Tuberculosis is one of the major infectious diseases and is both complex and serious. It is spread from person to person through the air, causing a public health burden, especially in low- and middle-income countries. This study aims to assess the knowledge on tuberculosis and the utilization of Directly-Observed Therapy, Short Course (DOTS) service from the public DOTS centers in Lalitpur district of Nepal. METHOD A structured questionnaire was used to collect data from 23 DOTS centers in Lalitpur district. Univariate and multivariate logistic regression was applied to assess the knowledge on tuberculosis and utilization of DOTS among people living with tuberculosis. RESULTS Among 390 respondents, 80% of patients had knowledge of tuberculosis and 76.92% utilized the DOTS service from the DOTS center. People of higher age (50-60 years) [aOR; 13.96, 95% CI 4.79,40.68], [aOR; 10.84,95% CI 4.09,28.76] had significantly more knowledge on TB and utilization of the DOTS service compared to the younger group. Additionally, those who completed twelfth class [aOR; 2.25, 95% CI 0.46,11.07] and [aOR;2.47, 95% CI 0.51,11.28] had greater knowledge of Tuberculosis and utilization of DOTS compared to those who had not completed twelfth class. Likewise, compared to urban residents, respondents in rural areas (aOR; 0.51, 95% CI 0.27,0.97) had less knowledge of tuberculosis, (aOR; 0.57, 95% CI 0.32,1) and less chance of utilization of the DOTS service from the DOTS center. CONCLUSION Approximately one quarter of patients did not have adequate knowledge of tuberculosis and were not utilizing the DOTS service, particularly in younger age groups, people living in a combined family, with no education, poor economic position, and from rural areas. Findings of this study revealed that some specific programs are needed for enhancing the knowledge and utilization of DOTS, particularly for those patients whose economic situations extended from low to mid range.

Arega B, Minda A, Mengistu G, Endale M, Agunie A. Unknown HIV status and the TB/HIV collaborative control program in Ethiopia: systematic review and meta-analysis. BMC Public Health 2020; 20:1021. [PMID: 32600287 PMCID: PMC7325261 DOI: 10.1186/s12889-020-09117-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 06/15/2020] [Indexed: 02/06/2023] Open
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.

Determinants of tuberculosis treatment outcome under directly observed treatment short courses in Adama City, Ethiopia. PLoS One 2020; 15:e0232468. [PMID: 32348358 PMCID: PMC7190142 DOI: 10.1371/journal.pone.0232468] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 02/18/2020] [Indexed: 12/30/2022] Open
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.

Chaves Torres NM, Quijano Rodríguez JJ, Porras Andrade PS, Arriaga MB, Netto EM. Factors predictive of the success of tuberculosis treatment: A systematic review with meta-analysis. PLoS One 2019; 14:e0226507. [PMID: 31881023 PMCID: PMC6934297 DOI: 10.1371/journal.pone.0226507] [Citation(s) in RCA: 55] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Accepted: 11/27/2019] [Indexed: 11/18/2022] Open
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.
