Assessment of proton-pump inhibitor use at a tertiary teaching hospital in Nigeria

Predictive Factors Associated with Inappropriate Intravenous Proton Pump Inhibitors Use in Hospitalized Patients: A Case-Control Study

Background and Objectives: Proton Pump Inhibitors (PPIs) are the most effective agents for treating acid-related gastrointestinal disorders. The prescription of an intravenous (IV) formulation of PPIs has increased dramatically. The aims of this study were to assess the appropriateness of IV PPI use and to define the risk factors and outcomes associated with its inappropriate use. Materials and Methods: A case-control retrospective study included all the hospitalized patients who received IV PPIs was conducted. Patient health records were reviewed, data were collected covering the period of the individual patients' admission to the hospital until discharge or death, and over the 3-month post-discharge period. The appropriateness of the IV PPI use and the resulting clinical outcomes were analyzed. Results: Overall, 540 patients were analyzed. Among them, 130/540 (24%) had inappropriate PPI use in terms of indication, dosage, and duration of treatment vs. 410 patients who had appropriate indications. Two parameters were associated with inappropriate use: congestive heart failure (OR 1.77; p = 0.02) and prescription of IV PPIs by surgeons vs. internists (OR 1.53; p = 0.05). Conclusions: Inappropriate IV PPI use is still common in daily clinical practice. Significant predictors of inappropriate use were the presence of congestive heart failure, elderly age, current use of anticoagulants and antithromotics, and the cases managed by surgeons, naturally due to suspected upper gastrointestinal bleedings.

Change in Prevalence and Pattern of Peptic Ulcer Disease in the Northern Savannah of Nigeria: An Endoscopic Study

Background

Peptic ulcer disease (PUD) is common worldwide. Its incidence and prevalence have been declining in recent years in developed countries, and a similar trend has been observed in many parts of Africa including Nigeria.

Aim

This study aimed to provide an endoscopic update on PUD in the Northern Savannah of Nigeria and compare with past reports from the region and recent reports from Nigeria, Africa, and the rest of the world.

Methods

Upper gastrointestinal endoscopy records of consecutive patients diagnosed with PUD between January 2014 and September 2022 at an endoscopy unit of a tertiary institution in North-West Nigeria were retrieved and demographic data, types of peptic ulcer, and their characteristics were extracted and analyzed.

Results

Over a 9-year period, 171/1958 (8.7%) patients were diagnosed with PUD: mean age 48.8 years (range 14-85), 68.4% male, and 70% >40 years. 59.6% were gastric ulcers (GU), 31.6% duodenal ulcers (DU), and 8.8% were both. The mean age of patients with GU was slightly higher than those with DU (49.9 years vs. 46.6 years, P = 0.29); patients aged <40 years were significantly more likely to be diagnosed with DU than GU (54.7% vs. 33.9%, P = 0.016) while those >40 years significantly more GU than DU (74.6% vs. 54.7%, P = 0.016). There were no significant gender differences between GU and DU.

Conclusion

The prevalence and pattern of PUD in Northern Savannah of Nigeria have changed - patients were predominantly male and older, and GU predominated.
