AB Levels of plasma lactoferrin are decreased in HIV-1-infected patients in
relation to the progression of the disease. Plasma lactoferrin
concentrations were determined using a specific and sensitive enzyme
immunoassay. 97 plasma were studied (22 asymptomatic, 45 symptomatic
patients compared to 30 healthy controls) and the results showed a
highly significant decrease (p < 0.001) of the level of lactoferrin in
HIV-1-infected patients (respectively 2.79 +/- 1.2 and 0.68 +/- 0.22
micrograms/ml) compared to controls (4.37 +/- 0.83 micrograms/ml). Since
it is well established that plasma lactoferrin level could be influenced
by the number of neutrophils, the experiments were reproduced in
neutropenic patients who represent 10% of recruitment (6 among 45
symptomatic patients). The plasma from neutropenic symptomatic patients
(neutrophils < or = 1,300/mm3) showed their mean lactoferrin level at
0.36 micrograms/ml still far above the normal values. In view of the
different reported biological effects of lactoferrin that are of great
importance in the non-specific defences, the real biological place of
the lack of such a molecule could be one important component of the
multifactorial nature of HIV-1 infection.
