NEW PATIENTS PRESENTING TO THEIR GP WITH DYSPEPSIA: DOES HELICOBACTER PYLORI ERADICATION MINIMISE THE COST OF MANAGING THESE PATIENTS?

Fifty-seven patients newly presenting to their GP with dyspepsia agreed to take part in a pharmacist-led clinic which tested and treated for Helicobacter pylori. Of these patients, 63% (36/57) tested positive and received eradication therapy. For 78% (28/36), eradication was successful with the first course of treatment, 89% (25/28) remaining symptom-free over the six-month follow-up. Eradication was successful for a further 17% (6/36) after a second attempt; again, these patients remained free of symptoms over the follow-up period. Thus, of the initial patients, 54% (31/57) were successfully treated, with no further symptoms. Such results had significant consequences on the expected direct cost of management per patient from a GP viewpoint. Using decision analysis it was found that H. pylori eradication for patients presenting with dyspepsia for the first time could result in considerable cost savings per patient in the long term.     

A DOUBLE-BLIND,COMPARATIVE STUDY OF DOTHIEPIN AND CLOMIPRAMINE IN THE TREATMENT OF MAJOR DEPRESSIVE ILLNESS

Dothiepin, a well-established antidepressant, has been compared with clomipramine in a single-blind study which demonstrated that dothiepin was better tolerated but there was no difference in efficacy. The present study was performed to recent European guidelines on good clinical practice using a randomised, double-blind, parallel-group methodology. One hundred and one patients suffering from major depressive disorder as defined by DSM-III-R were randomised to receive either clomipramine (25-150 mg daily) or dothiepin (75-150 mg daily) for up to six weeks. The clomipramine group comprised 51 patients, the dothiepin group 50 patients. At baseline, both groups had a mean age of 41-43 years and gave similar mean scores on the Hamilton Depression Rating Scale (23.5 for clomipramine, 23.6 for dothiepin). At endpoint it was reduced in both groups but there were no significant differences between the groups (mean change from baseline for the clomipramine and dothiepin groups was -14.6 and -14.1 respectively). Thirty-one clomipramine patients and 41 dothiepin patients completed six weeks' treatment. Withdrawal from treatment (20 patients for clomipramine, nine for dothiepin) was significantly different (p=0.0105). When reasons for withdrawal were analysed, 13 clomipramine patients and two dothiepin patients withdrew because of adverse events, this difference being significant (p=0.002). Thus both treatments were effective in treating patients suffering from major depressive disorder, but patients receiving dothiepin suffered fewer adverse events and were more likely to complete their treatment.
