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.

Chronic knee stiffness and swelling in a Zimbabwean adolescent.

A 12-year-old Zimbabwean girl presented with tuberculous monoarthritis. She was moderately wasted, stunted and sexually immature. These clinical findings lead to the diagnosis of underlying HIV infection, which was thought to have been acquired from mother-to-child transmission.

Cholangiocarcinoma presenting in an adolescent with vertically acquired HIV infection.

An adolescent with long-standing HIV infection who was severely immunosuppressed during HIV diagnosis developed cholangiocarcinoma 1.5 years after starting antiretroviral therapy.

A bitter pill to swallow: the need for better medications for drug-resistant tuberculosis in children.

The large and growing access gap between the number of children who become sick with drug-resistant tuberculosis (DR-TB) and those who are treated for the disease each year represents a significant health systems failure. While there are multiple reasons why children with DR-TB are not diagnosed and treated, a serious challenge is the medications used to treat the disease. This paper presents three child DR-TB cases who were treated incorrectly; the cases are used to illustrate some of the problems with existing second-line medications. Challenges, including the perception that the drugs are more dangerous than the disease, lack of proper dosing recommendations and formulations, and the high cost of current treatment, all contribute to a perverse situation in which the most vulnerable pediatric patients are provided with a lower standard of care. This situation can be reversed with novel partnerships and training models, pharmacokinetic studies of the relevant drugs, increased collaboration, and dedicated funding, grounded in a rights-based approach to DR-TB in children.

High rate of hypothyroidism among patients treated for multidrug-resistant tuberculosis in Lesotho.

BACKGROUND: Hypothyroidism is a known side effect of treatment for multidrug-resistant tuberculosis (MDR-TB), but it is considered to be rare. Hypothyroidism has vague and non-specific symptoms, and can be easily missed by clinicians. OBJECTIVE: To report the high rate of hypothyroidism in a cohort of MDR-TB patients in Lesotho and to describe our approach to diagnosis and management. DESIGN: A retrospective study of 212 patients who initiated treatment for MDR-TB in Lesotho between 27 July 2007 and 24 March 2009 was performed. RESULTS: Among 186 patients screened, 129 (69%) had hypothyroidism, defined as at least one documented thyroid-stimulating hormone (TSH) result > 10.0 mIU/l; 100 (54%) patients had a maximum TSH > 20.0 mIU/l. At 93 days after starting MDR-TB treatment, half of the patients had developed hypothyroidism. CONCLUSION: Hypothyroidism may be more common during MDR-TB treatment than previously recognized. Screening all patients, even those without symptoms, for hypothyroidism within 2-3 months of starting MDR-TB treatment should be considered until prospective studies can inform screening guidelines.
