ABSTRACT
ABSTRACT CONTEXT AND

OBJECTIVE:

Helicobacter pylori (H. pylori) is a chronic infectious pathogen with high prevalence. This study investigated the interaction between environmental tobacco exposure and H. pylori infection on the incidence of chronic tonsillitis in Chinese children. DESIGN AND

SETTING:

Cross-sectional study performed in an outpatient clinic in China.

METHODS:

Pediatric patients with chronic tonsillitis were enrolled. H. pylori infection was determined according to the presence of H. pylori CagA IgG antibodies. Serum cotinine levels and environmental tobacco smoke (ETS) exposure were determined for all participants.

RESULTS:

There was no significant difference in H. pylori infection between the children with chronic tonsillitis and children free of disease, but there was a significant difference in ETS between the two groups (P = 0.011). We next studied the association between ETS and chronic tonsillitis based on H. pylori infection status. In the patients with H. pylori infection, there was a significant difference in ETS distribution between the chronic tonsillitis and control groups (P = 0.022). Taking the participants without ETS as the reference, multivariate logistic regression analysis showed that those with high ETS had higher susceptibility to chronic tonsillitis (adjusted OR = 2.33; 95% CI 1.67-3.25; adjusted P < 0.001). However, among those without H. pylori infection, ETS did not predispose towards chronic tonsillitis.

CONCLUSION:

Our findings suggest that tobacco exposure should be a putative mediator risk factor to chronic tonsillitis among children with H. pylori infection.
RESUMO
RESUMO CONTEXTO E

OBJETIVO:

Helicobacter pylori (H. pylori) é um patógeno infeccioso crônico com alta prevalência. Este estudo investigou a interação entre exposição à fumaça ambiental do tabaco (FAT) e infecção pelo H. pylori sobre a incidência de amigdalite crônica em crianças chinesas. TIPO DE ESTUDO E LOCAL Estudo transversal desenvolvido num ambulatório na China.

MÉTODOS:

Pacientes pediátricos com amigdalite crônica foram recrutados. A infecção por H. pylori foi determinada segundo a presença de anticorpos H. pylori CagA IgG. Foi determinado o nível de cotinina sérica e exposição à FAT de todos os participantes.

RESULTADOS:

Não houve diferença significativa entre crianças com amigdalite crônica na infecção por H. pylori e sem amidalite, mas existia diferença significativa na FAT entre os dois grupos (P = 0,011). Em seguida, estudamos a associação entre FAT e amigdalite crônica com base no status de infecção por H. pylori. Nos pacientes com infecção por H. pylori, houve diferença significativa na distribuição de FAT entre os grupos de amigdalite crônica e controle (P = 0,022). Tomando os participantes sem FAT como referência, a análise de regressão logística multivariada mostrou que aqueles com alta FAT tinha maior susceptibilidade à amigdalite crônica (OR ajustado IC = 2,33, 95% 1,67-3,25, ajustado P < 0,001). No entanto, naqueles sem infecção por H. pylori, a FAT não predispôs a amigdalite crônica.

CONCLUSÃO:

Nossos achados sugerem que a exposição ao tabaco é um fator de risco para amigdalite crônica em crianças com infecção por H. pylori.
