Filariasis With Associated Urticaria Due To Wuchereria Bancrofti. Presented by Dr. Walter J. Cole and Dr. Frances M. Keddie.
The patient, P. D., a 45-year-old Ceylon-born Indian, has as his outstanding complaint chronic recurring urticaria of four years' duration.
In 1935, after the examination of routine blood films, he was given a diagnosis of filariasis. Except for his chronic urticaria, he has been entirely asymptomatic. From 1935 to 1948 he remained untreated. During 1948 and 1949 he received three seven-day courses of diethylcarbamazine (Hetrazan), with temporary remission of his microfilariasis but no change in the urticaria.
Physical examination of the patient at the present time is normal. Blood values were as follows: hemoglobin 16.6 gm.; white cell count 11,650, with lymphocytes 38%, monocytes 3%, neutrophiles 59%, eosinophiles, none. Erythrocyte sedimentation rate 10 mm. Packed cell volume 52 mm. The results of sérologie tests for syphilis were negative. Studies of the stool for parasites were negative.
