CONCLUSIONS: These data indicate that patients with adult OCD showed increased CD8+, i.e., suppressor T lymphocytes, and decreased CD4+, which identify helper T lymphocytes, as compared with a similar group of healthy control subjects. The findings appear peculiar to patients with OCD and are suggestive of an immunologic imbalance, which might be related to the stress deriving from the frustrating situation determined by the disorder itself.

Compared with healthy control subjects, individuals with childhood-onset obsessive-compulsive disorder (OCD) have been reported to have a higher percentage of B cells that react with the monoclonal antibody D8/17, a marker for rheumatic fever. This study sought to replicate these findings in adults with OCD. Double-blind analyses of blood samples from 29 consecutive adults with primary OCD and 26 healthy control subjects were conducted to determine the percentage of B cells identified by D8/17. Using a standard criterion of > or =12% labeled B cells to denote positivity, rates of D8/17 positive individuals did not significantly differ between the OCD (58.6%) and control (42.3%) groups. Early age of onset was not a predictor of D8/17 positivity in the OCD group. The percentage of B cells identified by the monoclonal antibody marker D8/17 did not distinguish adults with OCD from control subjects, nor did it distinguish a sub-group of adults with OCD who described pre-pubertal onset of their OCD symptoms.
