Abstract

Advanced HIV disease predisposes individuals to a wide and often concurrent spectrum of complications arising from opportunistic infections, immune dysregulation, direct viral injury, and treatment effects. In tuberculosis-endemic, resource-limited settings, disseminated tuberculosis frequently dominates clinical reasoning for multisystem disease in profoundly immunosuppressed patients - a cognitive default that risks failing to identify concurrent, independently treatable conditions. We describe a 35-year-old man with advanced HIV infection from central India who simultaneously developed parvovirus B19-associated marrow suppression, xanthogranulomatous pyelonephritis due to co-infection with carbapenem-resistant Escherichia coli and Mycobacterium chelonae, and symptomatic HIV-associated neurocognitive disorder (HAND) with myelopathy. To our knowledge, this represents the first reported case of M. chelonae pyelonephritis in a patient with HIV infection. This case report describes the diagnostic considerations for advanced HIV presenting as concurrent multisystem disease in a tuberculosis-endemic, resource-limited setting, and the clinical consequences of moving beyond the presumption of a single unifying aetiology.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
