![]() Breath testing for small intestinal bacterial overgrowth: maximizing test accuracy. SIBO may manifest with symptoms such as flatulence, steatorrhea, chronic diarrhea, abdominal distension, chronic abdominal pain, among others, or may be asymptomatic. Small intestinal bacterial overgrowth (SIBO) is characterized by an abnormal increase in the amount of bacteria in the lumen of the small intestine and/or the presence of atypical microbiota in this portion of the gastrointestinal tract. Intestino delgado Criança Adolescente Testes respiratórios Lactulose Crescimento ![]() Conclusões:Ĭrianças e adolescentes com SBID associado a doenças do trato gastrintestinal apresentam menores valores de peso e estatura. Nos pacientes com menos de 10 anos de idade, o escore Z de peso-idade foi menor nos pacientes com SBID (média=-0,968☑,359) do que nos sem SBID (média=-0,223☑,584) (p=0,026). Na comparação do escore Z de índice de massa corpórea-idade não foi observada diferença entre os grupos com (média=-0,489☑,528) e sem (média=-0,067☑,532) SBID (p=0,106). Não se observou associação entre SBID e sexo (masculino 27,4% e feminino 36,6% p=0,283). SBID foi caracterizado em 51 (31,5%) dos 162 pacientes. Foram determinadas as concentrações de hidrogênio e metano em aparelho 12i QuinTron MicroLyzer até 180 minutos após o início do teste respiratório. O teste respiratório foi realizado após ingestão de dez gramas de lactulose. Foram incluídos todos os 162 pacientes com idade inferior a 19 anos que realizaram teste respiratório para pesquisa de SBID entre 2011 e 2016. Métodos:Įstudo observacional e retrospectivo em ambulatório de gastroenterologia pediátrica. Intestine, small Child Adolescent Breath tests Lactulose GrowthĪvaliar a existência de associação entre sobrecrescimento bacteriano no intestino delgado (SBID) e comprometimento de peso e estatura em crianças e adolescentes com doenças do aparelho digestivo. The weight-for-age Z score was lower in patients with SIBO (mean=-0.96) than in those without SIBO (mean=-0.22) (p=0.02) Conclusions:Ĭhildren and adolescents with SBIO associated with diseases of the gastrointestinal tract have lower weight and height values. The BMI of patients with SIBO (median=15.39) was lower than of those without it (median=16.06) however, the statistical analysis was not significant (p=0.052). There was no difference between the BMI-for-age Z score of patients with (mean=-0.48) and without SIBO (mean=-0.06) (p=0.106). mean=-0.59 25 th and 75 th percentile: -1.57 and 0.22 p=0.04) was demonstrated in children with SIBO when compared with children without it. A lower median of height-for-age Z score (mean=-1.32 25 th and 75 th percentile: -2.12 and -0.08 vs. There was no association between gender and SIBO (male 26.3% vs. There was no difference between the age of those with (mean=8.7y.o 25 th and 75 th percentile: 4.6 and 11.3) and without (mean=7.9y.o 25 th and 75 th percentile: 4.8 and 12.2) SIBO (p=0.910). SIBO was identified in 51 (31.5%) patients. The concentration of hydrogen and methane was measured for 180 minutes after the beginning of the test by 12i QuinTronMicroLyzer device. Breath test was collected after the intake of 10 grams of lactulose. All 162 patients aged less than 19 years old who underwent breath test in search of SIBO between 20 were studied. To evaluate the association between small intestinal bacterial overgrowth (SIBO) and weight and height impairment in children and adolescents with gastroenterology diseases.
