Clinical Studies on Urticaria

Abstract

Clinical surveys were carried out on 26 patients with urticaria: acute type, 9; chronic type, 17. In cases of the acute type was no sex difference, but incidence of cases of the chronic type was remarkably higher in the females than in the males. Incidences of cases with a positive family history of atopic diseases were higher in the chronic type than in the acute type. The main provocative causes were foods in both types, but physical stress was also an important causative factor in the chronic type. The laboratory examinations showed: the urine negative in all cases; eosinophilia in 2 out of 10 in the chronic type: stools positive for the ova of ascaris in one out of 11 cases: cases; abnormalities of BSP, CCF, and TTT test in 14.3%, 23%, and 18% of chronic type, respectively. Incidences of positive skin reactions to miscellaneous allergenic extracts prepared by the Torii Pharmaceutical Co. were in 11.5 to 75% of the acute type (highest incidences in the case of mat and tomato extracts) and in 7.7 to 71.4% of the chronic type (highest incidences in the case of tomato and lobster extracts).
