Abstract

Idiopathic CD4+ lymphocytopenia is a disorder associated with low CD4+ T cell count and opportunistic infections resembling AIDS. Most cases are described in developed countries. We report two HIV-negative patients with idiopathic CD4+ lymphocytopenia and AIDS-defining events diagnosed in Djibouti. The first patient developed lesions of Kaposi’s sarcoma and the second one presented with pulmonary tuberculosis. Both patients died with severe immunodepression. In poor resource-areas where HIV testing may not be available it is important to bear in mind that severe immunodepression and a clinical presentation compatible with AIDS do not necessary carry the diagnosis of AIDS.

Key words: Human immunodeficiency virus, Acquired immunodeficiency syndrome, Lymphopenia, Kaposi’s sarcoma, tuberculosis, Djibouti.
