Isoniazid preventive therapy (IPT) is a strategy that has been proposed by the National Department of Health of South Africa and the World Health Organization for people living with HIV (PLWH) to prevent latent tuberculosis (TB) progressing to active TB. This research focused on exploring and describing experiences of PLWH regarding IPT provision in the Ngaka Modiri Molema district in the North West province of South Africa. A qualitative, exploratory, contextual and descriptive research design was used for this study. Semi-structured individual interviews were conducted to collect data from PLWH. The sample size consisted of 14 participants and data saturation was reached at participant 11. A thematic data analysis was employed in this study. The study consisted of 10 female participants and 4 male participants. Three main themes emerged during interviews, namely factors that facilitate IPT provision and uptake, factors that inhibit the adherence of patients to IPT, and strategies to improve provision or adherence. The provision of IPT at a community health centre in Ngaka Modiri Molema district municipality was reported to be satisfactorily although challenges were also marked. IPT must be available at all times to ensure the promotion of PLWH adherence, continuity of care and retention in HIV care. In addition, screening of PLWH for active TB disease before they can be initiated should be a priority. PLWH should be supported and followed up through the directly observed treatment, short-course strategy to promote adherence and this can also be facilitated through adherence social clubs.

Background Information on how well Isoniazid Preventive Therapy (IPT) works on reducing TB incidence among people living with HIV (PLHIV) in routine settings using robust statistical methods to establish causality in observational studies is scarce. Objectives To evaluate the effectiveness of IPT in routine clinical settings by comparing TB incidence between IPT and non-IPT groups. Methods We used data from PLHIV enrolled in 315 HIV care and treatment clinic from January 2012 to December 2016. We used Inverse Probability of Treatment Weighting to adjust for the probability of receiving IPT; balancing the baseline covariates between IPT and non-IPT groups. The effectiveness of IPT on TB incidence was estimated using Cox regression using the weighted sample. Results Of 171,743 PLHIV enrolled in the clinics over the five years, 10,326 (6.01%) were excluded leaving 161,417 available for the analysis. Of the 24,800 who received IPT, 1.00% developed TB disease whereas of the 136,617 who never received IPT 6,085 (4.98%) developed TB disease. In 278,545.90 person-years of follow up, a total 7,052 new TB cases were diagnosed. Using the weighted sample, the overall TB incidence was 11.57 (95% CI: 11.09–12.07) per 1,000 person-years. The TB incidence among PLHIV who received IPT was 10.49 (95% CI: 9.11–12.15) per 1,000 person-years and 12.00 (95% CI: 11.69–12.33) per 1,000 person-years in those who never received IPT. After adjusting for other covariates there was 52% lower risk of developing TB disease among those who received IPT compared to those who never received IPT: aHR = 0.48 (95% CI: 0.40–0.58, P<0.001). Conclusion IPT reduced TB incidence by 52% in PLHIV attending routine CTC in Tanzania. IPTW adjusted the groups for imbalances in the covariates associated with receiving IPT to achieve comparable groups of IPT and non-IPT. This study has added evidence on the effectiveness of IPT in routine clinical settings and on the use of IPTW to determine impact of interventions in observational studies.

Abstract Background: Isoniazid Preventive Therapy (IPT) reduced Tuberculosis (TB) among People Living with HIV (PLHIV). Despite this, uptake has been reported to be sub-optimal . We describe characteristics of visits in which PLHIV were screened TB negative (as the main source for IPT initiation), determine characteristics of visits in which PLHIV were initiated on IPT as well as determined factors associated with IPT initiation to inform program scale up and improve quality of service.Methods : Retrospective cohort study design which involved PLHIV enrolled into care and treatment clinics in Dar es Salaam, Iringa and Njombe regions from January 2012 to December 2016. The study aimed at evaluating implementation of IPT among PLHIV. Data analysis was conducted using STATA.Results: A total 173,746 were enrolled in CTC in the 3 regions during the period of follow up and made a total of 2,638,876 visits. Of the eligible visits, only 24,429 (1.26%) were initiated on IPT. In multivariate analysis, 50 years and more (aOR=3.42, 95% CI: 3.07-3.82, P<0.01), bedridden functional status individuals with bedridden functional status (aOR=4.56, 95% CI:2.45-8.49, P<0.01) and WHO clinical stage II had higher odds of IPT initiation (aOR=1.18, 95% CI:1.13-1.23, P<0.01). Furthermore, enrolment in 2016 (aOR=2.92, 95% CI:2.79-3.06, P<0.01), enrolment in hospitals (aOR=1.84, 95% CI:1.77-1.90, P<0.01), enrolment in public health facilities (aOR=1.82, 95% CI: 1.75-1.90, P<0.01) and been on care for more than one year (aOR=6.77, 95% CI: 5.25-8.73, P<0.000) were also more likely to be initiated on IPT. Enrollment in Iringa (aOR=0.44, 95% CI: 0.41-0.47, P<0.01) and good adherence (aOR=0.56, 95% CI 0.47-0.67, P<0.01) was less likely to be initiated on IPT.Conclusions: Our study documented low IPT initiation proportion among those who were enrolled in HIV care and eligible in the 3 regions during the study period. Variations in IPT initiation among regions signals different dynamics affecting IPT uptake in different regions and hence customized approaches in quality improvement. Implementation research is needed to understand health system as well as cultural barriers in the uptake of IPT intervention.
