[Epidemiology of inflammatory bowel diseases in Veszprém county of Western Hungary between 1977 and 2001].

Abstract：

INTRODUCTION:An epidemiological study of inflammatory bowel disease (IBD) in Veszprém county (located in western part of Hungary) was carried out from 1977 to 2001. METHODS:Both hospital and outpatient records of IBD patients were collected reviewed carefully. Most patients have been followed up regularly. RESULTS:The number of population has decreased during the observed period from 386,000 to 376,000. The county has both industrial and agrarian parts. 560 new ulcerative colitis (UC) cases, 212 Crohn's disease (CD), and 40 indeterminate colitides (IC) were diagnosed in the investigated period. Incidence rate increased from 1.66 (1977-1981) to 11.01 (1997-2001) in UC, and from 0.41 to 4.68 in CD, respectively. The incidence rate in IC rose from 0.26 to 0.74. The M/F ratio in UC was 1.06, in CD: 1.03, respectively, 41 UD patients and 13 CD patients died, the cause of death was disease related in 6 UC and in 6 CD patients. The average age at death in UC was not different from that observed in general population (66.4 years) but in CD (50.1 years) it was much earlier. The disease related mortality was low, 0.06/100,000 both in UC and CD. The prevalence rate at the end of 2001 was 142.6 for UC and 52.9/100,000 inhabitants for CD. Mean age at onset in UC was 38.9 +/- 15.5 years, in CD 31.7 +/- 12.8 years. We observed only one peak onset of the diseases, in UC it was between 30 and 40 years, in CD between 20 and 30 years. People living in towns were more liable to acquire the disease (ORUC = 1.27, ORCD = 1.13). The rate of smokers at the onset was 14.3% (OR = 0.25) in UC and 50.5% (OR = 1.98) in CD. Ex-smokers were 18.4% and 6.4%. Family history of IBD was present in 3.4% in UC and 9.9% in CD. The location of UC (according to the known largest extent) was proctitis in 112 cases, proctosigmoiditis in 162 cases, left sided colitis in 117 and subtotal or pancolitis in 169 cases. The location of CD was only ileal in 68 cases, ileocolonic in 87 cases, colonic in 57 cases. The behaviour of CD was non-stricturing-non-penetrating in 63 cases, stricturing in 54 cases, penetrating in 95 cases. 59.4% of the CD patients had at least one operation, 6.1% had more than 3 operations. CONCLUSION:The incidence and prevalence rates have increased steadily in Veszprém County, now it reaches that of most western European countries. There were no gender differences either in UC or CD. Smoking seemed to be a risk factor for CD, but it was preventive for UC. The rapid increase in incidence supports a role for environmental (e.g. diet, lifestyle changes) risk factors.
