Resumen

FIGUEIREDO, José Fernando de Castro et al. Survival and infectious processes in pacients with AIDS: analysis according to inicial serum vitamin A levels. Rev. Soc. Bras. Med. Trop. [online]. 2001, vol.34, n.5, pp. 429-435. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822001000500005.

Patients with Aids (n = 39) were followed up for a maximum period of 36 weeks, after which the types and topographies of infectious complications presented and patient survival were analyzed and correlated with the vitamin A levels presented by the patients at the beginning of clinical follow-up. Twenty-one (53,8%) patients presented serum retinol levels below 1.6mmol/L, 12 (57%) of whom had values lower than 1.05mmol/L. There was no correlation between low serum vitamin A levels and the types or topographies of the infectious complications that occurred during the follow-up period. Although mean survival at the end of the 36 months follow-up period was similar for the two groups, patients with retinol deficiency presented a lower probability of survival during the first 24 months of follow-up compared to patients without hypovitaminosis A (8.44 x 1.42 months; p = 0.003).
