This prospective open-label extension study was carried out to evaluate the effectiveness of sildenafil (Viagra) in the treatment of male erectile dysfunction in Nairobi, Kenya. A total of 219 adult male patients with erectile dysfunction were instructed to take 50 mg, 25 mg, or 100 mg of sildenafil orally 1 hour prior to planned sexual activity, but not more than once every 24 hours. Patients were reviewed at 4-week intervals for 16 weeks to assess the efficacy and adverse effects of the drug. The age range was 33-80 years with a mean of 62.5 years and a peak incidence in the 60-69 year age group. The causes of erectile dysfunction were organic (n = 119, 54.34%), psychogenic (n = 85, 38.81%), and mixed (n = 15). 200 patients (91.32%) had improved sexual function after treatment with Viagra. This improvement included improved erectile and orgasmic functions and overall sexual satisfaction. 157 patients responded to the 50-mg treatment regimen; 40, to the 25-mg regimen; and 3, to the 100-mg regimen. No improvement in sexual function was reported in 19 patients (8.68%) after Viagra administration. In addition, 7 patients reported mild and transient adverse effects of the drug, including mild headache, dyspepsia, facial flushing, nausea, and vomiting. In conclusion, oral sildenafil (Viagra) is an effective well-tolerated and simple treatment for male erectile dysfunction in the majority of cases. However, the cost of treatment may prohibit and limit its wide use by many deserving patients in this area.

Background. Helicobacter pylori is associated with several upper gastrointestinal conditions including chronic gastritis, peptic ulcer disease, and gastric malignancy. Proton pump inhibitor-based triple therapies are considered the standard regimens for H. pylori eradication, but the optimal duration of therapy is controversial. To prevent infection and complications, local studies should be undertaken to evaluate H. pylori eradication rates in a country. Objectives. We compared 7-day and 14-day regimens to determine the optimum duration of triple therapy for H. pylori eradication. Methods. We undertook a prospective randomised comparative trial of 7-day and 14-day triple therapy regimen for H. pylori eradication at the Aga Khan University Hospital, Nairobi; 120 patients with dyspepsia and H. pylori infection were randomised to receive esomeprazole, amoxicillin and clarithromycin for either 7 days (EAC 7) or 14 days (EAC 14). Compliance and side-effects were assessed 2 weeks after the start of therapy and H. pylori eradication was assessed by stool antigen tests 4 weeks after treatment. Results. Both the intention-to-treat (ITT; N=120) and per protocol (PP; N=97) analyses showed no significant differences between the eradication rates of EAC 7 (ITT 76.7%; PP 92%) and EAC 14 (ITT 73.3%; PP 93.6%) (ITT p=0.67; PP p=0.76). Poor compliance was reported in one patient in the EAC 14 group. The incidence of adverse events was comparable in the two groups. Conclusion. One-week and 2-week triple treatments for H. pylori eradication are similar in terms of efficacy, safety and patient compliance.
