Helicobacter pylori Management in Africa: A Survey of Diagnostic, Treatment, and Related Resources.

BACKGROUND

Although Helicobacter pylori infection (H. pylori) prevalence in Africa has declined in the last decade, it remains concerningly high. H. pylori is asymptomatic in the majority of patients but is associated with significant morbidity and mortality in 10%-20%.

MATERIALS AND

METHODS

We conducted an online survey of 21 African countries, with the link distributed to members of the African Helicobacter Microbiota Study Group. The survey was completed by 562 respondents; the majority were from Nigeria (27.2%), South Africa (18.1%), Tanzania (17.6%), Egypt (16.9%), and Cameroon (14.2%).

RESULTS

The most common reason for H. pylori testing was dyspepsia in 83.9% of the cases. Abnormal findings at gastroscopy (62.3%) and heartburn (61.7%) were also common indications. Stool antigen testing and histological examination of gastric biopsies using Giemsa were the two most used methods for H. pylori testing at 62.3% and 50.3%, respectively. Most respondents reported the use of standard clarithromycin-based triple therapy as first-line treatment for H. pylori infection.

CONCLUSION

This survey has demonstrated the diversity of practice and resource availability within the African continent. Several international guidelines exist on the management of H. pylori, but little data is available in Africa on how this condition is managed in every day clinical practice. There is an urgent need to formulate evidence-based and locally relevant practice guidelines on the African continent. In this context, the African Helicobacter and Microbiota study group was formed to coordinate efforts across the continent on H. pylori research to provide guidance on its management. This paper, therefore, aimed to evaluate the practice of H. pylori diagnostics and management, as well as related resources in representative countries in Africa, to facilitate the development of such guidelines.
