AB A CD8 hyperlymphocytosis is observed in 5 to 10% of HIV infected
patients. It has been related to a diffuse visceral infiltration: The
SICCA syndromee whose clinical observation can be compared to the
Gougerot-Sjogren one. Its pronostic value is not clearly established.
Seventeen HIV 1 seropositive patients (15 male and 2 female) showing a
persistant CD8 hyperlymphocytis (more than 1200/mm3 circulating CD8 rate
during more than 3 months) have been studied. 7 patients presented an
opportunist infection in spite of high CD4 rates (> 400/mm3). The
research of a CD8 visceral infiltration by salivary glands biopsy ocular
examination, and broncho-alveolar lavage, was done in 5 patients. No
infiltration syndrome has been found. Only one patient showed a CD8
lymphocytary alveolite without phenotypic particularity. The blood
lymphocytes phenotypes of 17 patients were studied. In CD4 population
there is an imbalance between the CD4 + CD45RA + (memory cells) which
have increased and the CD4 + CD45RA +C (virgin cells) which have
decreased. In CD8 population, we found an hyperactivation similar the
one existing in seropositive patients without CD8 hyperlymphocytosis.
The dosage of interleukines IL2, IL4, IL6, TNF alpha and gamma
interferon, done in 6 patients is normal. The study of the lymphocytes
function effected in 5 patients shows an absence or diminution of the T
proliferative response to soluble tuberculine; streptococcic and CMV
antigenes and to Pokeweed Mitogen (PKW) constrasting with the
persistance of responses to MLR and PHA. In conclusion: The existence of
a major CD8 hyperlymphocytosis is not always correlated to the existence
of a visceral CD8 infiltration syndrome. CD8 hyperlymphocytis seems to
be at the origine of an imbalance of the different CD4 sub-population
with an increase of the memory cells and a functionnel deficit to the T
proliferative response, responsible for an actual immunodepression not
correlated to the CD4 numbers. The HIV patients with CD8
hyperlymphocytose may show opportunist infections as a result of the
functional deficit of the auxillary T cells independantly from the
absolute CD4 number and this must raise the question of the indication
of an antiretroviral treatment.
