Abstract
The chemotactic and random mobility functions of twelve selectively IgA‐deficient patients were evaluated by a method using agarose gel. A severe polymorphonuclear cellular chemotactic defect was found in ten out of twelve patients, but only five of them also showed a marked associated impairment of random locomotory function. Furthermore, in one subject, levamisole therapy resulted in a dramatic improvement of both chemotactic and random mobility functions. These results are discussed in the paper with respect to the possible pathogenetic implications.
