Determining of survival & hazard in patients with Pemphigus in Kerman

The incidence of survival analysis and hazard rates in 55 patients with the pemphigus have been determined for a period of 12 years from 1989- 2000. The effect of pemphigus type, sex, age and the method of treatment were evaluated separately. For this equation ht(x)=ho(t) exp {?? i Xi} was chosen in which ho is the baseline hazard in zero time, ht is hazard happened later (in time t),? is regression coefficient and X can be age, sex, pemphigus type and method of treatment. Results of this study revealed that the upper age groups had relatively smaller survival chance than those of lower age groups, and women less than men. The first 8 years after pemphigus diagnosis, patients with vulgaris and vogtan type as compared with foliaceae and etythmatous had also less survival chance, so was combined therapy compared with single therapy (Corticosteroides). Other parameters like job type and place of living had no apparent effect.
