Fas is a protein that plays a major role in the apoptotic mechanism of several cell types, including white blood cells (WBC). Mutations of the Fas gene in humans are known to lead to autoimmune lymphoproliferative syndrome (ALPS). Glucocorticoids or cytostatic drugs are sometimes used to treat the lymphoproliferation in these patients. When treated with the anti-malaria drug Fansidar, a patient with ALPS showed a marked shrinkage of the lymph node masses, decrease in peripheral blood lymphocytes (PBL) and an increase in neutrophil numbers. In addition, an increased Fas expression was seen on all types of leucocytes.

Autoimmune lymphoproliferative syndrome (ALPS) is a paediatric disease characterized by lymphoproliferation and autoimmunity. Most patients are known to carry heterozygous mutations of the TNFRSF6 gene leading to diminished Fas-mediated apoptosis and failure of activated lymphocytes to undergo apoptosis. A subgroup of patients without the TNFRSF6 gene mutation has similar defective apoptosis and clinical features. No effective treatment has been reported so far. Glucocorticoids, intravenous immunoglobulin and/or immunosuppressive drugs have usually led to only transient clinical improvement. Seven ALPS patients (two type Ia and five type III) were treated with the antimalarial drug Fansidar. No toxicity was observed. An objective response was seen in six of them and, in two, the treatment was stopped without reappearance of the symptoms. Moreover, a marked decrease in interleukin-10 levels was observed in two patients during the treatment. We found that the drug induced apoptosis in activated lymphocytes through activation of the mitochondrial apoptotic pathway.
