We studied serum anti-streptococcal antibodies (anti streptolysin O, anti Deoxyribonuclease B, and anti-streptokinase (ABcam-ELISA, USA) in 76 cases with psychiatric manifestation (OCD, ADHD) in compare with 39 healthy controls. These antibodies were studied in 53 cases with movement disorders (Tic/Tourette syndrome) in compare with 76 healthy controls. Sensitivity, specificity and positive predictive value of tests were calculated.
Results:
In movement disorders ASOT, Anti-DNase and Anti streptokinase was significantly higher than controls (P< 0.0001, P= 0.000, P< 0.00001)
