Meta-Análise: Prevalência de Doença Úlcera Péptica Não Helicobacter pylori, Não-AINE

Resumo original em inglês

O que aconteceu

Non-Helicobacter pylori (H. pylori), non-nonsteroidal anti-inflammatory drug (NSAID) peptic ulcer disease (PUD) is increasingly recognized as a distinct subgroup, but its proportion across clinical presentations remains unclear.

We aimed to estimate this proportion.

We searched MEDLINE, Embase and CENTRAL from their inception to March 2026 for observational studies. The primary outcome was the proportion of non-H. pylori, non-NSAID PUD among adults with overall, bleeding and perforated PUD. Random-effects meta-analysis of logit-transformed proportions was performed using restricted maximum likelihood. Meta-regression assessed associations with study year, country-level H. pylori prevalence and region. Protocol registered in PROSPERO (CRD420251174202).

O que encontraram

Overall, 92 studies (60,816 patients) from 32 countries were included. The pooled proportions of non-H. pylori, non-NSAID PUD cases were 13.0% (95% confidence interval [CI], 10.4-16.2) in overall PUD, 11.3% (95% CI, 8.8-14.4) in bleeding PUD, and 22.0% (95% CI, 13.1%-34.7%) in perforated PUD. In univariable meta-regression, a more recent study year was associated with a higher proportion of bleeding PUD (β = 0.076; 95% CI, 0.031-0.120). This association remained statistically significant after adjustment for country-level H. pylori prevalence (β = 0.070; 95% CI, 0.026-0.113). Lower H. pylori prevalence was also associated with a higher proportion after further adjustment for region (β = -0.025; 95% CI, -0.046 to -0.005).

Por que isso importa

Non-H. pylori, non-NSAID PUD represents a non-negligible but heterogeneous component of PUD. In bleeding PUD, exploratory ecological analyses suggest a temporal increase, potentially reflecting evolving etiologic patterns beyond H. pylori infection and NSAID exposure.
