Costs of distributing HIV self-testing kits in Eswatini through community and workplace models

BACKGROUND

This study evaluates the implementation and running costs of an HIV self-testing (HIVST) distribution program in Eswatini. HIVST kits were delivered through community-based and workplace models using primary and secondary distribution. Primary clients could self-test onsite or offsite. This study presents total running economic costs of kit distribution per model between April 2019 and March 2020, and estimates average cost per HIVST kit distributed, per client self-tested, per client self-tested reactive, per client confirmed positive, and per client initiating antiretroviral therapy (ART).

METHODS

Distribution data and follow-up phone interviews were analysed to estimate implementation outcomes. Results were presented for each step of the care cascade using best-case and worst-case scenarios. A top-down incremental cost-analysis was conducted from the provider perspective using project expenditures. Sensitivity and scenario analyses explored effects of economic and epidemiological parameters on average costs.

RESULTS

Nineteen thousand one hundred fifty-five HIVST kits were distributed to 13,031 individuals over a 12-month period, averaging 1.5 kits per recipient. 83% and 17% of kits were distributed via the community and workplace models, respectively. Clients reached via the workplace model were less likely to opt for onsite testing than clients in the community model (8% vs 29%). 6% of onsite workplace testers tested reactive compared to 2% of onsite community testers. Best-case scenario estimated 17,458 (91%) clients self-tested, 633 (4%) received reactive-test results, 606 (96%) linked to confirmatory testing, and 505 (83%) initiated ART. Personnel and HIVST kits represented 60% and 32% of total costs, respectively. Average costs were: per kit distributed US$17.23, per client tested US$18.91, per client with a reactive test US$521.54, per client confirmed positive US$550.83, and per client initiating ART US$708.60. Lower rates for testing, reactivity, and linkage to care in the worst-case scenario resulted in higher average costs along the treatment cascade.

CONCLUSION

This study fills a significant evidence gap regarding costs of HIVST provision along the client care cascade in Eswatini. Workplace and community-based distribution of HIVST accompanied with effective linkage to care strategies can support countries to reach cascade objectives.

Bedaquiline and delamanid result in low rates of unfavourable outcomes among TB patients in Eswatini

SETTING: Since 2015, Eswatini has been scaling up bedaquiline (BDQ) and delamanid (DLM) based drug-resistant TB treatment regimens under programmatic conditions.OBJECTIVE: Identification of factors associated with treatment outcomes in patients receiving BDQ and/or DLM either as a new treatment initiation or drug substitution.DESIGN: This is a retrospective cohort study of patients receiving BDQ and/or DLM in Eswatini between March 2015 and October 2018. We describe factors associated with unfavourable treatment outcomes (death, lost to follow-up, treatment failure and amplification of resistance) and culture conversion using multivariable flexible parametric survival and competing-risks regression analyses.RESULTS: Of 352 patients receiving BDQ and/or DLM, 7.8% and 21.2% had an unfavourable treatment outcome at 6 and 24 months, respectively. Predictors were age ≥ 60 years (adjusted hazard ratio aHR 4.49, 95%CI 1.61–12.57) vs. age 20–39 years, and a treatment regimen combining both drugs (aHR 4.49, 95%CI 1.61–12.57) vs. BDQ only. The probability of culture conversion was increased for two health facilities and patients with a poly resistance profile (adjusted sub-hazard ratio 2.01, 95%CI 1.13–3.59) vs. multidrug resistance.CONCLUSION: Single use of BDQ or DLM was associated with low rates of unfavourable outcomes, suggesting that these medications may be effectively adopted at scale under routine programmatic conditions. Combined use of BDQ and DLM was a risk factor for unfavourable outcomes and should prompt for collection of more data on the combined use of these medications.

Anti-diabetic activity of Aloe excelsa

OBJECTIVE

To investigate the effect of Aloe excelsa powder on diabetes.

DESIGN

The experiment was carried out in the laboratory on both normal and diabetic rats. Diabetes was induced in the rats by using streptozotocin. Thereafter, blood samples were taken from both the normal and diabetic rats and the sugar levels measured by using the Accutrend Alpha blood glucose monitoring kit.

SETTING

The experiment was conducted in the laboratory in the Faculty of Medicine at the University of Zimbabwe.

SUBJECTS

A total of 280 male albino rats weighing 250 g on average were used. They were obtained from the Animal House of the Medical School at the University of Zimbabwe.

MAIN OUTCOME MEASURES

Reduction in sugar levels.

RESULTS

The Aloe excelsa powder produced a dose-dependent reduction in the blood glucose in blood glucose levels. It also compared well with the effect of insulin.

CONCLUSION

This study shows that Aloe excelsa has significant activity on glucose levels in rats and this, therefore, confirms the claims by traditional healers that this plant has anti-diabetic effects.

Premature luteinization is not eliminated by pituitary desensitization with leuprolide acetate in women undergoing gonadotrophin stimulation who demonstrated premature luteinization in a prior gonadotrophin-only cycle

A total of 40 women who demonstrated premature luteinization (serum progesterone > or = 3.5 nmol/l (1.1 ng/ml) on or before the day of human chorionic gonadotrophin (HCG) administration) during ovarian stimulation with human menopausal gonadotrophins (HMG) were restimulated in 46 subsequent cycles after pituitary desensitization with the gonadotrophin-releasing hormone agonist (GnRHa, 1 mg), leuprolide acetate. Five women were treated with a double dose of agonist (2 mg) when premature luteinization was determined on the single dose protocol. In HMG-only cycles, a frank luteinizing hormone (LH) surge was detected in 30 cycles; 15 cycles were cancelled because of premature ovulation. In agonist cycles there were no cancellations, although 25 cycles demonstrated premature luteinization and in six cycles a frank LH surge was detected. Doubling the dose of the agonist did not prevent premature luteinization. Agonist cycles with and without premature luteinization did not differ in any in-vitro fertilization (IVF) outcome parameters (ampoules of gonadotrophins, day of HCG administration, peak oestradiol concentration, number of oocytes retrieved, fertilized, transferred or cryopreserved). We conclude that in patients who demonstrate premature luteinization in a gonadotrophin-only cycle, pituitary desensitization may not completely eliminate subtle luteinization or a frank LH surge.
