Evaluation of pathergy test in North Jordan

The positivity of pathergy's test in Behçet disease varies throughout the world. We tried to evaluate its diagnostic significance in known Behçet patients in the region of North Jordan. Twenty-two patients were tested, readings were taken after 48 hours. The patients were not tested previously and a comparison between the subcutaneous injection of 0.1 ml normal saline and skin puncture was recorded. The development of a skin eruption (papule, nodule, pustule) were observed and described. The percentage of positivity was 20% in the studied population. The patients tested who were not taking medication at the time of the procedure are more likely to illustrate a positive Pathergy reaction.
