Fiebre VIH+

emDocs - March 19, 2015 - By Levi Kitchen
"In the febrile HIV patient, there are many diagnostic dilemmas and potential life-threatening disease processes which make the diagnosis and treatment difficult. When approaching these patients, it is useful to separate complications into organ systems and then try to estimate the patient’s immune status if it is not known. CD4 counts > 500 cells/uL indicate early infection where the most common infections are similar to non-HIV infected people. The risk for opportunistic infections (OI) changes as the disease progresses and CD4 count drops, decreasing the body’s cell-mediated and humoral immunity capabilities.
In general, CD4 values < 500 cells/uL, < 200 cells/uL and < 50 cells/uL correspond with mild, moderate and severe immune impairment respectively. While these classifications are important for risk stratification, they are less important in the ED setting where real-time CD4 counts are almost never available."
