Nutritional status and its response to treatment of children, with and without HIV infection, hospitalized for the management of tuberculosis

Abstract

Background: The association of childhood tuberculosis (TB) and malnutrition is known, but treatment response, the influence of the acute-phase response (APR) and concomitant HIV infection are not well documented. Aim: To evaluate the nutritional response and APR in HIV-infected and uninfected children hospitalised for the treatment of TB and receiving standard anti-tuberculosis chemotherapy. Methods: During a study of the pharmacokinetics of standard anti-tuberculosis agents, anthropometric parameters were measured and blood concentrations of nutrients and C-reactive protein (CRP) determined at 1 and 4 months after initiation of chemotherapy. Results: 24 HIV-infected and 34 HIV-uninfected children were studied. On enrolment, 31.6% of HIVinfected and 2.9% of HIV-uninfected children were underweight, and 31.6% and 14.7%, respectively, were stunted. Mean values of weight, height/length, head circumference and mid-upper arm circumference on enrolment and at 4-month assessment in HIV-infected and -uninfected children did not differ. Conclusion: A majority of HIV-infected and uninfected children had an APR but it had resolved by 4 months in most HIV-uninfected children. In both groups, low and declining skinfolds and a persistently low AMA indicate a persistent disturbance of fat and protein metabolism, despite successful chemotherapy.
