[Biology of human immunodeficiency virus infection].
This review will describe the current state of basic knowledge on the acquired immune deficiency syndrome (AIDS), which has now spread worldwide becoming an acute public health problem in western countries and in Africa. AIDS is a viral infection, due to a retrovirus designated human immune deficiency virus (HIV), which affects the immune system resulting in a wide array of secondary manifestations which include opportunistic infections, neoplasia, autoimmune phenomena, neurologic disorders, and hematologic abnormalities. AIDS has now been recognized in the pediatric population, and infection occurs by perinatal and blood-borne transmission. As a consequence, pediatricians are no more involved only by a theoretical point of view (AIDS is a perfect model of interaction of virus with the immune system), but also by an operative point of view. Knowledges on immunological modifications in AIDS and on the underlaying features of the HIV are essential for the clinical approach. This goal may be difficult, if one considers that the pace of research in AIDS and the progress attained to date are unprecedent. However, clinicians must be aware that the ultimate solution of clinical problems in AIDS exclusively depends on sound basic research.
