Abstract: HIV/AIDS can cause malnutrition directly and also indirectly through opportunistic infections (OIs). Infectious diarrhoea and tuberculosis are the commonest OIs linked to malnutrition in HIV/AIDS. Environmental enteric dysfunction has now been identified to play a significant role in HIV-malnutrition. Food insecurity is bidirectionally associated with aggravation and perpetuation of HIV infection. Increasingly, drugs used in antiretroviral therapy have been recognised to lead malnutrition in many ways. Both HIV and malnutrition are most prevalent in the poorest areas of the world, and there is a convergence of etiological factors. Malnutrition depresses every aspect of immune function. Deficiency of key micronutrients like iron, folic acid, zinc, selenium and vitamins A, C and D also adversely affects immune function. Recent research has led to a greater understanding of these mechanisms. Immune dysfunction secondary to malnutrition is referred to as nutrition-associated immunodeficiency. Hence it is easy to surmise that malnutrition and HIV/AIDs are a deadly duo.
