High uptake of antiretroviral therapy among HIV-positive TB patients receiving co-located services in Swaziland.

ABSTRACT: Swaziland has the highest adult HIV prevalence and second highest rate of TB/HIV coinfection globally. Recently, the Ministry of Health and partners have increased integration and co-location of TB/HIV services, but the timing of antiretroviral therapy (ART) relative to TB treatment-a marker of program quality and predictor of outcomes-is unknown.We conducted a retrospective analysis of programmatic data from 11 purposefully-sampled facilities to evaluate timely ART provision for HIV-positive TB patients enrolled on TB treatment between July-November 2014. Timely ART was defined as within two weeks of TB treatment initiation for patients with CD4<50/?L or missing, and within eight weeks otherwise. Descriptive statistics were estimated and logistic regression used to assess factors independently associated with timely ART.Of 466 HIV-positive TB patients, 51.5% were male, median age was 35 (interquartile range [IQR]: 29-42), and median CD4 was 137/?L (IQR: 58-268). 189 (40.6%) were on ART prior to, and five (1.8%) did not receive ART within six months of TB treatment initiation. Median time to ART after TB treatment initiation was 15 days (IQR: 14-28). Almost 90% started ART within eight weeks, and 45.5% of those with CD4<50/?L started within two weeks. Using thresholds for "timely ART" according to baseline CD4 count, 73.3% of patients overall received timely ART after TB treatment initiation. Patients with CD4 50-200/?L or ?200/?L had significantly higher odds of timely ART than patients with CD4<50/?L, with adjusted odds ratios of 11.5 (95% confidence interval [CI]: 5.0-26.6) and 9.6 (95% CI: 4.6-19.9), respectively. TB cure or treatment completion was achieved by 71.1% of patients at six months, but this was not associated with timely ART.This study demonstrates the relative success of integrated and co-located TB/HIV services in Swaziland, and shows that timely ART uptake for HIV-positive TB patients can be achieved in resource-limited, but integrated settings. Gaps remain in getting patients with CD4<50/?L to receive ART within the recommended two weeks post TB treatment initiation.

Project description:BACKGROUND: Significant adverse events (AE) have been reported in patients receiving medications for multidrug- and extensively-drug-resistant tuberculosis (MDR-TB & XDR-TB). However, there is little prospective data on AE in MDR- or XDR-TB/HIV co-infected patients on antituberculosis and antiretroviral therapy (ART) in programmatic settings. METHODS: Médecins Sans Frontières (MSF) is supporting a community-based treatment program for drug-resistant tuberculosis in HIV-infected patients in a slum setting in Mumbai, India since 2007. Patients are being treated for both diseases and the management of AE is done on an outpatient basis whenever possible. Prospective data were analysed to determine the occurrence and nature of AE. RESULTS: Between May 2007 and September 2011, 67 HIV/MDR-TB co-infected patients were being treated with anti-TB treatment and ART; 43.3% were female, median age was 35.5 years (Interquartile Range: 30.5-42) and the median duration of anti-TB treatment was 10 months (range 0.5-30). Overall, AE were common in this cohort: 71%, 63% and 40% of patients experienced one or more mild, moderate or severe AE, respectively. However, they were rarely life-threatening or debilitating. AE occurring most frequently included gastrointestinal symptoms (45% of patients), peripheral neuropathy (38%), hypothyroidism (32%), psychiatric symptoms (29%) and hypokalaemia (23%). Eleven patients were hospitalized for AE and one or more suspect drugs had to be permanently discontinued in 27 (40%). No AE led to indefinite suspension of an entire MDR-TB or ART regimen. CONCLUSIONS: AE occurred frequently in this Mumbai HIV/MDR-TB cohort but not more frequently than in non-HIV patients on similar anti-TB treatment. Most AE can be successfully managed on an outpatient basis through a community-based treatment program, even in a resource-limited setting. Concerns about severe AE in the management of co-infected patients are justified, however, they should not cause delays in the urgently needed rapid scale-up of antiretroviral therapy and second-line anti-TB treatment.

Project description:BackgroundInvestigation of household contacts exposed to infectious tuberculosis (TB) is widely recommended by international guidelines to identify secondary cases of TB and limit spread. There is little data to guide the use of contact investigations outside of the household, despite strong evidence that most TB infections occur outside of the home in TB high burden settings. In older adolescents, the majority of infections are estimated to occur in school. Therefore, as part of a project to increase active case finding in Swaziland, we performed school contact investigations following the identification of a student with infectious TB.MethodsThe Butimba Project identified 7 adolescent TB index cases (age 10-20) with microbiologically confirmed disease attending 6 different schools between June 2014 and March 2015. In addition to household contact investigations, Butimba Project staff worked with the Swaziland School Health Programme (SHP) to perform school contact investigations. At 6 school TB screening events, between May and October 2015, selected students underwent voluntary TB screening and those with positive symptom screens provided sputum for TB testing.ResultsAmong 2015 student contacts tested, 177 (9%) screened positive for TB symptoms, 132 (75%) produced a sputum sample, of which zero tested positive for TB. Household contact investigations of the same index cases yielded 40 contacts; 24 (60%) screened positive for symptoms; 19 produced a sputum sample, of which one case was confirmed positive for TB. The odds ratio of developing TB following household vs. school contact exposure was significantly lower (OR 0.0, 95% CI 0.0 to 0.18, P = 0.02) after exposure in school.ConclusionSchool-based contact investigations require further research to establish best practices in TB high burden settings. In this case, a symptom-based screening approach did not identify additional cases of tuberculosis. In comparison, household contact investigations yielded a higher percentage of contacts with positive TB screens and an additional tuberculosis case.

Project description:BACKGROUND: The impact of the human immunodeficiency virus (HIV) on tuberculosis (TB), and the implications for TB and HIV control, is a public health challenge in Ghana - almost a quarter (23%) of all TB cases were HIV positive in 2010. The integration of TB/HIV services has therefore emerged as an essential component of the national response to TB and HIV. The aim is to reduce fragmentation, improve access, enhance efficiency and improve quality of care. Ghana's TB/HIV policy comprises three linked sets of activities: effective implementation of the Stop TB Strategy for TB control, improved HIV prevention and care, and the implementation of additional TB/HIV activities. Different models of service delivery with increasing integration of TB/HIV activities are expected to provide greater access to more comprehensive care. The objective of this paper is to assess the impact of TB/HIV integration on TB treatment outcomes and to explore the usefulness of TB treatment outcomes as TB/HIV indicators. METHODS: A before-and-after study to observe the introduction of TB/HIV activities into TB programmes in three hospitals with different levels of integration was conducted. Anonymised patient data was collated from TB registers from each facility, and analysed to determine if TB treatment outcomes changed significantly after integration. RESULTS: TB treatment success was 50% (95% CI 49 - 52) prior to, and 69% (95% CI 65 - 73) after, integration (?2 43.96, p < 0.00). Treatment success increased from 43% to 53% at the one-stop shop (OSS), from 69% to 78% at the partially integrated site (PIS) and substantially from 46% to 78% at the referral site (RS) (?2 64.54; p<0.01). Defaults and cases transferred out reduced from 14.3% and 15.3% prior to integration, to 1.4% and 9.0% after integration, respectively, accounting for a significant increase in treatment success. Death rates remained high at 18% in all cases studied and 25% in HIV-associated cases after integration. CONCLUSION: TB/HIV integration may improve TB treatment success, but its exact impact is difficult to ascertain due to non-specificity and design limitations. TB mortality may be more useful as an indicator for monitoring TB/HIV activities in Ghana.
