The immunostatus of T helper and T cytotoxic cells in the patients ten years after exposure to sulfur mustard.

The treatment and cure of patients exposed to sulfur mustard is a remaining challenge despite ongoing research in this field. A severe suppression of the immune system still remains the major cause of opportunistic infections, septicemia, and death in these patients. The patients evaluated in this study were classified into three groups; severe, moderate, and mild according to the severity of exposure to sulfur mustard.
