BACKGROUND
Diagnosing tuberculosis (TB), the leading cause of death in people with HIV, remains a challenge in resource-limited countries. We assessed TB diagnosis using a strategy that included systematic urine lipoarabinomannan (LAM) testing for all HIV patients hospitalized in the medical wards and 6-month mortality according to the LAM result.
METHODS
This prospective, observational study included adult HIV patients hospitalized in the medical wards of a public district hospital in Malawi regardless of their TB symptoms or CD4 count. Each patient had a clinical examination and Alere Determine TB-LAM, sputum microscopy, sputum GeneXpert MTB/RIF (Xpert), chest X-ray, and CD4 count were systematically requested.
RESULTS
Among 387 inpatients, 54% had a CD4<200 cells/µL, 64% had presumptive TB and 90% had ≥1 TB symptom recorded in the medical file. LAM results were available for 99.0% of the patients, microscopy for 62.8% and Xpert for 60.7%. In total, 26.1% (100/383) had LAM-positive results, 48% (48/100) of which were grades 2-4. Any TB laboratory test result was positive in 30.8% (119/387). Among patients with no Xpert result, 28.5% (43/151) were LAM-positive. Cumulative 6-months mortality was 40.1% (151/377): 50.5% (49/97) in LAM-positives and 36.2% (100/276) in LAM-negatives, p=0.013. In multivariable regression analyses, LAM-positive patients had higher risk of mortality than LAM-negatives (aOR: 2.5, 95%CI: 1.1-5.8, p=0.037).
CONCLUSIONS
In resource-limited hospital medical wards with high TB prevalence, a diagnostic strategy including systematic urine-LAM testing for all HIV patients is an easily implementable strategy that identifies a large proportion of patients with TB at risk of death.

SETTING
Papua New Guinea (PNG) has one of the world’s highest TB incidence rates. It is difficult for patients to access TB care in remote provinces due to insufficient infrastructure and challenging terrain, making varied, targeted delivery models for treating TB necessary.
OBJECTIVE
To assess treatment outcomes using self-administered treatment (SAT), family-supported treatment and community-based directly observed therapy (DOT) via treatment supporter (TS) in the PNG context.
DESIGN
A retrospective, descriptive analysis of routinely collected data from 360 patients at two sites in 2019–2020. All patients were assigned a treatment model based on risk factors (adherence or default) and offered patient education and counselling (PEC), family counselling and transportation fees. End-of-treatment outcomes were assessed for each model.
RESULTS
Treatment success rates among drug-susceptible TB (DS-TB) were good overall: 91.1% for SAT, 81.4% for family-supported treatment and 77% for DOT patients. SAT was strongly associated with favourable outcomes (OR 5.7, 95% CI 1.7–19.3), as were PEC sessions (OR 4.3, 95% CI 2.5–7.2).
CONCLUSION
By considering risk factors when determining their treatment delivery model, strong outcomes were seen in all three groups. Multiple modes of treatment administration, tailored to individuals’ needs and risk factors, is a feasible, effective, patient-centred care model for hard-to-reach, resource-limited settings.
