title: [Hyperprolactinemia is a frequent finding in HIV infection but does not correlate with viral burden].
abstract: Although many authors have reported the finding of hyperprolactinemia during the course of HIV infection, the circumstances determining the rise of prolactin (PRL) concentrations in serum are poorly understood. To analyze the relationships between serum PRL and other clinical variables in HIV-infected patients, 46 HIV-infected patients and 17 seronegative controls were studied. Serum PRL concentrations were significantly higher in the HIV-infected group (p = 0.022). Furthermore, Serum PRL and serum IgG correlated positively (Rs = 0.42; p = 0.05, Spearman-Rank). On the contrary, serum PRL concentrations did not correlate with the plasmic viral burden (Rs 0.039; p = 0.841), Our data confirm that hyperprolactinemia is a frequent finding during the course of HIV infection, and that serum PRL are independent of viral replication kinetics. Considering that a positive correlation was found between serum PRL and immunoglobulins, it is possible that serum PRL might increase in response to non specific immunological activation, or even in response to immunological activation at the onset of infections.
