    Description / Table of Contents: Zusammenfassung Bei fünf Patienten mit Morbus Wilson (n=2 ohne Leberzirrhose,n=3 mit Leberzirrhose ohne portale Hypertonie) fand sich ein normaler Sekretin-Pankreozymin-Test; bei einem weiteren mit Leberzirrhose, aber ohne portale Hypertonie, war das Pankreas bei der Sektion histologisch unauffällig. Bei zwei Patienten mit Leberzirrhose und portaler Hypertonie zeigte sich dagegen eine verminderte Bikarbonatsekretion (n=1) und eine eingeschränkte Amylasesekretion (n=2). Die Pankreasfunktion normalisierte sich in einem Fall parallel mit einer Normalisierung des vorher pathologisch erhöhten Pfortaderdrucks unter Penicillamin-Therapie. Es wird geschlossen, daß eine Pankreasfunktionsstörung bei Morbus Wilson mit der Entwicklung und dem Fortschreiten einer Leberzirrhose zusammenhängt und nicht Ausdruck einer primären Organmanifestation ist.
    Notes: Summary A normal exocrine pancreatic function was demonstrated by the secretin-pancreozymin-test in five patients with Wilson's disease either without (n=2) or with cirrhosis of the liver but without portal hypertension (n=3). In another patient with cirrhosis of the liver without portal hypertension the pancreas was normal at post mortem examination. In two patients with cirrhosis of the liver and portal hypertension bicarbonate (n=1) and amylase secretion (n=2) were diminished. The regression of portal hypertension under therapy with penicillamine in one of the latter cases was paralleled by the return to normal of exocrine pancreatic function. It is concluded that exocrine pancreatic insufficiency in Wilson's disease is dependent on the development and the progression of chirrhosis of the liver and not due to a primary manifestation of the disease itself.

    Notes: Summary The influence of a 4-week treatment with the substituted benzimidazole omeprazole (20 mg daily) or placebo on gastric endocrine function was tested in healthy male volunteers. Compared with placebo-treated subjects basal serum gastrin levels were slightly but significantly increased after treatment with omeprazole from 10 to 22 pg/ml (medians;P〈0.05) but returned to pretreatment values after 2 weeks recovery (9 pg/ml). Antral gastrin tissue concentration increased and was still elevated after recovery; however, antral gastrin concentrations also increased in placebo controls, and increments immediately after cessation of omeprazole treatment (2.58 µg/g; median) were not significantly over control values (1.92 µg/g;P〉0.1). Postprandial gastrin release, basal and food-stimulated insulin release, antral somatostatin concentration, and volume densities of antral G and D cells were unaffected. It is concluded that, due to incomplete inhibition of gastric acid secretion at the omeprazole dose studied, only slight effects on the endocrine stomach are to be expected after 4 weeks of administration of omeprazole.

    Notes: Serum gastrin was determined in 33 patients during treatment with the proton pump inhibitor omeprazole. After 4 weeks of therapy, gastrin levels increased to a median of 55 pg/ml compared to 15 pg/ml prior to omeprazole (P 〈 0.001). There was a close correlation (r= 0.939; P 〈 0.001) between pre-treatment gastrin and levels at 4 weeks. Comparison of serum gastrin concentrations at I month of omeprazole with levels at 6 (n= 21) and 12 months (n= 12) continuous therapy revealed a close correlation (r= 0.961 and r= 0.882, respectively; P 〈 0.001) despite dose adjustment. In marked hypochlorhydria documented by continuous pH monitoring, serum gastrin varied from normal up to profound hypergastrinaemia. These results demonstrate that the serum gastrin increase under powerful acid-inhibitory drug therapy depends upon a number of variables. (a) Only in patients with elevated gastrin levels, prior to omeprazole treatment, can moderate to marked hypergastrinaemia during omperazole be expected. (b) Gastrin increases reached during the initial period of omeprazole treatment remain constant during long-term therapy. (c) Acid inhibition itself is not necessarily associated with an increase in serum gastrin in every patient, which suggests that the individual sensitivity of the gastrin cell to acid inhibition is more important for serum gastrin changes than the degree of acid inhibition itself.

    Notes: Metabolic sequelae of profound and long-lasting inhibition of gastric acid secretion by omeprazole have largely been neglected. Data from long-term studies suggest that vitamin B12 stores decrease slightly over several years, although this was not clinically relevant within the first 4 years of therapy. Additionally, it cannot be completely ruled out that patients with an increased iron demand may develop iron deficiency, but data available at present do not provide any evidence that iron malabsorption is to be expected under normal conditions. Protein homeostasis and calcium metabolism seem to be unaffected by long-term omeprazole therapy. Based upon present experience, serum cobalamin concentration should be monitored in patients undergoing omeprazole therapy for several years.

    Notes: The efficacy of omeprazole therapy (40 mg daily) in H2-blocker refractory severe reflux oesophagitis (Grade II-IV; Savary and Miller classification) was investigated in 61 patients. Mean duration of reflux disease and preceding H2-antagonist treatment were 4.3 years and 15 months, respectively. Healing rates at 4, 8 and 12 weeks were 48%, 80% and 92%, respectively. There was a correlation between severity of oesophagitis and duration of omeprazole therapy necessary for healing. Three patients (5%) required higher dosages than 40 mg for healing. Symptomatic responses paralleled healing. It is concluded that omeprazole is a highly effective drug for severe reflux oesophagitis not responding to H2-blocker treatment and that 40 mg daily is the optimal dose.

    Notes: Pantoprazole is a benzimidazole derivative which selectively inhibits the proton pump H+, K+-ATPase necessary for the final step in gastric acid secretion.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To investigate the tolerability and the prophylactic effect of pantoprazole 40 mg once daily on relapse in patients whose reflux oesophagitis had been healed.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:The safety of pantoprazole 40 mg once daily was assessed in an open 1-year trial on 222 patients whose reflux oesophagitis had been healed with omeprazole or pantoprazole. Relapse was defined as endoscopically-confirmed reflux oesophagitis (at least Grade I), with endoscopies being performed for patients experiencing 3 consecutive days of disease-specific symptoms.〈section xml:id="abs1-4"〉〈title type="main"〉Results:Kaplan–Meier survival analysis at 6 and 12 months gave estimated treatment failure rates of 2% and 6% from confirmed relapses (per-protocol), and of 9% and 30% for a worst-case group (all withdrawals counted as failures). The only population shift in laboratory variables was a doubling of the median serum gastrin level over the first 6 months; thereafter it stabilized. Fifty-four (24%) patients experienced adverse events; 15 of these withdrew. Serious adverse events were reported for 12 patients.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Pantoprazole appears to be highly effective and to have a good safety profile for long-term prophylaxis of reflux oesophagitis.
