AB We present the case of a 47-year-old patient who was seen for recurrent
opportunistic infections. Immunophenotypic analyses disclosed severe
reduction of CD4+ T cells. Repeated Elisa, Western blot and polymerase
chain reaction tests for HIV were negative. The low CD4+ T lymphocyte
count unaccompanied by increased CD8+ T lymphocytes and
hypergammaglobulinemia, along with negativity for HIV infection,
suggested the diagnosis of idiopathic CD4+ lymphocytopenia (ICL). The
patient's clinical manifestations and laboratory results conformed with
the case definition of ICL established in 1992 by the Centers for
Disease Control of Atlanta, i.e., CD4+ T cells < 300/mm3 on two
occasions and no evidence of HIV infection. In vitro analyses evidenced
depressed lymphoproliferative responses to mitogens such as concanavalin
A and pokeweed mitogen, while the expression of Fas antigen on
peripheral lymphocytes and the percentage of apoptotic cells after
propidium iodide staining were increased. Since in vitro concanavalin A
stimulation inhibits T cell proliferation and induces apoptosis, these
results suggest that the patient's lymphocytes are susceptible, in vivo,
to an apoptotic signal.
