The epidemiology of primary biliary cirrhosis in southern Israel.

BACKGROUND: The epidemiology of primary biliary cirrhosis has changed significantly over the last decade, with a trend towards increasing prevalence in many places around the world. OBJECTIVES: To determine the overall prevalence of PBC in southern Israel and the specific rates for different immigrant groups between January 1993 and October 2004. METHODS: Multiple case-finding methods were used to identify all cases of PBC in the study region. Age-adjusted prevalence rates were compared among the different immigrant groups. RESULTS: A total of 47 cases of PBC were identified with an overall prevalence of 55 cases per million. All patients were women, and all except for a Bedouin Arab were Jewish. Foreign-born patients comprised 70% of our PBC cohort even though they represent only 45.4% of the regional population. This predominance of immigrants did not change when the rates were adjusted for age (P < 0.001). The prevalence rates were 40, 177, and 58 cases per million for those born in Israel, North Africa or Asia, and Eastern Europe, respectively. The age-specific prevalence rate for women older than 40 years varied from 135 cases per million among those born in Israel to 450 among immigrants from Eastern Europe and the former USSR to 700 cases per million among immigrants from North Africa and Asia. CONCLUSIONS: The prevalence of PBC in southern Israel is similar to that reported from some European countries. The rate is much higher among Jews than Arabs and among immigrants to Israel compared to native Israelis.

Budesonide foam vs. hydrocortisone acetate foam in the treatment of active ulcerative proctosigmoiditis.

INTRODUCTION: Rectal administration of corticosteroids is advocated in patients with proctosigmoiditis who have failed therapy with mesalamine enema. Foam offers patients better tolerability than an enema. In this study the efficacy and adverse effects of a new budesonide foam are compared with the presently available hydrocortisone foam. METHODS: Two hundred fifty-one patients with proctosigmoiditis were randomly assigned to receive either budesonide foam or hydrocortisone foam for eight weeks. RESULTS: Remission rates were comparable in the budesonide and hydrocortisone groups, 53 and 52 percent, respectively. The mean disease activity index for the two groups decreased to a similar extent, from 7.2 +/- 1.9 and 7 +/- 2 to 3.6 +/- 3.1 and 3.9 +/- 3.4 in the budesonide and hydrocortisone groups, respectively. In a subgroup of patients who had not responded to rectal administration of mesalamine, 23 of 44 (52 percent) patients who received budesonide responded favorably to the foam, as compared with 14 of 38 (37 percent) patients who received hydrocortisone (P = not significant). Low plasma cortisol occurred in 3 percent of the budesonide group and in none of the hydrocortisone patients. CONCLUSIONS: This trial demonstrates a similar efficacy and safety of the two foams in patients with proctosigmoiditis.
