PEPTIC ULCER

1900 – 1950: increasing incidence 1930: % of the population diagnosis by X-ray etiology: excess acidification by: infection (teeth,tonsils) stress/emotion:fear,horror deep disgust PEPTIC ULCER

Bertram Welton Sippy (1866–1924) was born in the village of Neptune in Richland County, Wisconsin. After 2 years at the University of Wisconsin he transferred to Rush Medical College in Chicago where he was awarded his MD degree in He took a job as a railroad surgeon in Montana in order to obtain funds for an 18-month tour of hospitals and clinics in Europe, including a stint with the famed Professor Carl Ewald in Berlin. On his return to Chicago he set up a practice of internal medicine, with an emphasis on neurology but without neglect of the broader field. He quickly acquired a reputation as an astute diagnostician and superb teacher. It is said his showmanship held his students spellbound and doubtlessly contributed to his success with patients. An ardent believer in Schwartz’ dictum (“No acid, no ulcer”), he promoted for the treatment of acute peptic ulcer disease a strict regimen of hourly milk and cream feedings supplemented by frequent, large doses of antacids and often by periodic gastric aspiration. A generation of physicians found this a highly effective means of hastening the healing of peptic ulcers. Unfortunately, the Sippy regimen did little to prevent ulcer recurrence, and Sippy’s program was later superceded by more efficacious therapy

Peptic ulcer epidemiology 1984 US: :decrease in hospitalization rates for DU,not for GU ● low rates in summer ? ● smoking,aspirin,steroids ● genetic factors Kurata JH 1984

Ulcer EPIDEMIOLOGY peak around 1950: ca 8 % of the working population disease of middle-aged DU: male-female ratio 2-4/1 genetic influences: blood group 0 poorer part of the population war and social unrest: increased incidence tobacco,alcohol,ulcerogenic drugs

Is Hp the primary cause of DU ? Arguments against: 1. Regional and ethnic differences in DU prevalence in countries with high prevalence of Hp 2. Prevalence of Hp-negative DU 3. DU-recurrence after Hp -eradication

Recurrent peptic ulcers after successful Hp-eradication Multicenter study: 4940 patients ● Ulcer recurrence (NSAIDs excluded): 1,9 % / year 84 % recurred at the same site as the previous ulcers Hiroto Miwa 2004

Hp-negative/NSAIDs-negative peptic ulcer prevalence ● different data: high in US, Asia and Australia low in Europe: Freston (USA) : 11 – 44 % (1) Kent-Man Chu (Hong Kong): 29,6 % of 1343 pat. (2) Arroyo (Spain) : 2,1 % of 754 pat. (3) Arents (Drente) : 4,9 % of 405 pat. (4) Xia (Australia) : 43 % (5) 1.Aliment Pharmacol Ther, World J Gastroenterol Helicobacter Eur J Gastroenterol Drugs 1999

Hp-negative/NSAIDs-negative DU characteristics Compared with Hp-positive DU: - older age - more concomitant problems - pre-existing malignancy - recent surgery - underlying sepsis - relative acid hypersecretion - reduced efficacy of antisecretory drugs Kent-Man Chu,2005 Freston,2001 Hung,2005

Peptic ulcer disease in patients with chronic liver disease Compared with the general population patients with cirrhosis have: ● higher bleeding complications ● delayed healing ● greater ulcer recurrence rates ● less benefit from Hp- eradication

The effects of eradication of Helicobacter pylori on the recurrence of duodenal ulcer in patients with cirrhosis Liver cirrhosis + DU: 102 patients ● Hp + : 54 (52%) ● Hp - : 50 (48%) Recurrence after 1 year: ● After Hp eradication: 21/36 58 % ● Hp+ after eradication: 8/18 44 % ● Hp - : 24/50 48 % Lo et al. Gastrointest Endosc 2005

Conclusions ● Peptic ulcer is still a multifactorial disease Hp and NSAIDs are not the only factors Idiopathic ulcers (Hp-neg,NSAID-neg) are difficult to treat Peptic ulcers in patients with liver cirrhosis are often not related to Hp
