Quality of life in patients with heartburn but without esophagitis: effects of treatment with omeprazole.Am J Gastroenterol. 1999 Jul; 94(7):1782-9.AJ
Because improvement in quality of life (QoL) is an important therapeutic goal in patients with heartburn but without esophagitis, the aim of the present study was to compare the impact of omeprazole 20 mg or 10 mg daily with that of placebo on QoL in patients with heartburn as the predominant symptom.
QoL was measured at baseline and after 4 wk using two validated questionnaires, the Psychological General Well-Being (PGWB) index and the Gastrointestinal Symptom Rating Scale.
The two questionnaires were completed by 163 patients in the omeprazole 20 mg group, 163 in the omeprazole 10 mg group, and 82 in the placebo group. The reflux dimension of the Gastrointestinal Symptom Rating Scale showed a significant improvement in terms of reflux symptoms on omeprazole 20 mg versus omeprazole 10 mg and placebo, and on omeprazole 10 mg compared with placebo. The total score of the PGWB index improved significantly more on both doses of omeprazole than on placebo. The mean scores rose from 96.8 to 103.9 on omeprazole 20 mg, from 98.4 to 106.0 on omeprazole 10 mg, and from 98.0 to 100.6 on placebo. All dimensions of the PGWB index improved on treatment with omeprazole, but the improvements were most pronounced in the dimensions depicting anxiety, depressed mood, and self-control.
It is concluded that treatment with omeprazole 20 mg and omeprazole 10 mg restores QoL to a level comparable with that observed in a healthy population.
