TB and HIV stigma compounded by threatened masculinity: implications for TB health-care seeking in Malawi.

SETTING: Urban Blantyre, Malawi. OBJECTIVE: To understand why men with tuberculosis (TB) in the community remain undiagnosed. DESIGN: A multi-method qualitative study applying a modified grounded theory approach. Data were gathered from March 2011 to March 2012 from 134 men and women taking part in 1) focus group discussions with community members (n = 6) and health care workers (n = 2), and 2) in-depth interviews with TB patients (n = 20, females n = 14) and chronic coughers (n = 20, women n = 8). Data were analysed inductively to identify, refine and consolidate, and verify emerging concepts and themes. RESULTS: Two emerging themes highlighting compound stigma in this high human immunodeficiency virus (HIV) prevalence, low-income setting are presented. First, cough or any illness that portended a 'serious' condition were accompanied by portrayals of cough, TB and HIV as being interchangeable. Chronic coughers and TB patients described their illness in ways that foregrounded bodily decimation and rupture of social life and masculine identity. Second, 'resistance strategies' entailed resisting classification as (seriously) ill by evading or ambivalently approaching health care, or acknowledging the 'ill' status then actively pursuing health-appropriate behaviours, including changing lifestyle or adopting non-normative gender roles. CONCLUSIONS: Managing patients requires 1) going beyond syndromic management based on vital signs and clinical indicators to recognising and intervening on health care-seeking related tensions to retain individuals in care, and 2) understanding and addressing TB stigma as it manifests and affects men and women differently in specific settings.

High mortality and prevalence of HIV and tuberculosis in adults with chronic cough in Malawi: a cohort study.

BACKGROUND: Adults with suspected tuberculosis (TB) in health facilities in Africa have a high risk of death. The risk of death for adults with suspected TB at community-level is not known but may also be high. METHODS: Adults reporting cough of ⩾ 2 weeks (coughers) during a household census of 19,936 adults in a poor urban setting in Malawi were randomly sampled and age-frequency matched with adults without cough ⩾ 2 weeks (controls). At 12 months, participants were traced to establish vital status, offered human immunodeficiency virus (HIV) testing and investigated for TB if symptomatic (sputum for Xpert(®) MTB/RIF, smear microscopy and culture). RESULTS: Of 345 individuals with cough, 245 (71%) were traced, as were 243/345 (70.4%) controls. TB was diagnosed in 8.9% (16/178) of the coughers and 3.7% (7/187) of the controls (P = 0.039). HIV prevalence among coughers was 34.6% (56/162) and 18.8% (32/170) in controls (P = 0.005); of those who were HIV-positive, respectively 26.8% and 18.8% were newly diagnosed. The 12-month risk of death was 4.1% (10/245) in coughers and 2.5% (6/243) in controls (P = 0.317). CONCLUSION: Undiagnosed HIV and TB are common among adults with chronic cough, and mortality is high in this urban setting. Interventions that promote timely seeking of HIV and TB care are needed.

Markers to differentiate between Kaposi's sarcoma and tuberculous pleural effusions in HIV-positive patients.

BACKGROUND: Kaposi's sarcoma (KS) and tuberculosis (TB) commonly cause pleural effusions in high human immunodeficiency virus (HIV) burden resource-limited countries. Differentiating between them is challenging, as pleural biopsy and TB culture are rarely available. OBJECTIVES: To identify markers to differentiate between TB effusions and KS effusions in HIV-positive patients, and to compare liquid culture and Xpert MTB/RIF in pleural fluid. METHODS: Fifty HIV-positive patients with pleural effusions recruited in Malawi underwent pleural ultrasound and aspiration. Fluid visual inspection, cell count, bacterial culture, glucose/protein, solid and liquid TB culture and Xpert were performed. RESULTS: The mean age of the patients was 32 years; 30/50 (60%) were male and 29 (58%) had cutaneous/oral KS. Thirteen (26%) pleural fluid samples were liquid culture-positive for TB, while 9/13 (69%) were Xpert-positive. Three (10.3%) KS patients had culture-positive TB effusions; 17 (58.6%) had KS effusions. The relative risk of TB in KS patients increased with limited KS, loculated fluid and low glucose. Eleven (52.3%) non-KS patients had culture-positive TB effusions associated with male sex, straw-coloured fluid and fibrin stranding on ultrasound. CONCLUSIONS: KS patients were most likely to have KS effusion, but TB should be considered. Most non-KS patients had TB, supporting the use of World Health Organization guidelines. Xpert identified two thirds of liquid culture-positive results.
