Yoga Therapy for Abdominal Pain-Related Functional Gastrointestinal Disorders in Children: A Randomized Controlled Trial.

OBJECTIVES: The aim of the present study was to compare effects of 10 weeks of yoga therapy (YT) and standard medical care (SMC) on abdominal pain and quality of life (QoL) in children with abdominal pain-related functional gastrointestinal disorders (AP-FGIDs). METHODS: Sixty-nine patients, ages 8 to 18 years, with AP-FGIDs, were randomized to SMC complemented with YT or SMC alone. YT is a mixture of yoga poses, meditation, and relaxation exercises and was given once a week in group sessions. SMC consisted of education, reassurance, dietary advice, and fibers/mebeverine, if necessary. Pain intensity (pain intensity score [PIS] 0-5) and frequency (pain frequency score [PFS] 0-4) were scored in a pain diary, and QoL was measured with KIDSCREEN-27. Follow-up was 12 months. Treatment response was defined as ≥50% reduction of weekly pain scores. RESULTS: At 1-year follow-up, treatment response was accomplished in 58% of the YT group and in 29% of the control group (P = 0.01); no significant differences for other time points were found. YT, and not SMC, resulted in a significant reduction of PIS (P < 0.01) and PFS (P < 0.01) after 12 months. During the study, however, YT was not significantly superior compared with SMC. Subanalyses for time points demonstrated a significant greater reduction of PIS at 12 months in favor of YT. No differences were found for QoL. YT was more effective in the reduction of reported monthly school absence (P = 0.03). CONCLUSION: At 1-year follow-up, YT in addition to standard care was superior compared with SMC according to treatment success, PIS, and reduction of school absence. YT, however, was not significantly more effective in improving PFS or QoL, compared with SMC.

Glucose hydrogen breath test for small intestinal bacterial overgrowth in children with abdominal pain-related functional gastrointestinal disorders.

OBJECTIVES: A potential link between small intestinal bacterial overgrowth (SIBO) and abdominal pain-related functional gastrointestinal disorders (AP-FGID) has been suggested by symptom similarities and by the reported prevalence of SIBO in children with irritable bowel syndrome (IBS) and functional AP. The aim of this study is to evaluate the prevalence of SIBO using the glucose hydrogen breath test (GHBT), in a cohort of Dutch children with AP-FGID fulfilling the Rome III criteria, and to identify potential predictors. METHODS: Children ages 6 to 18 years with AP-FGID fulfilling the Rome III criteria were included. All of the children underwent a GHBT. SIBO was diagnosed if the fasting breath hydrogen concentration was ≥20 ppm or an increase in H2 levels of ≥12 ppm above the baseline value was measured after ingestion of glucose. Gastrointestinal symptoms were collected using a standardised AP questionnaire. RESULTS: A total of 161 Dutch children with AP-FGID were enrolled. Twenty-three patients (14.3%) were diagnosed as having SIBO, as assessed by GHBT; 78% of the children diagnosed as having SIBO had fasting hydrogen levels ≥20 ppm. IBS was significantly more found in children with SIBO compared with children without SIBO (P = 0.001). An altered defecation pattern (ie, change in frequency or form of stool) (P = 0.013), loss of appetite (P = 0.007), and belching (P = 0.023) were significantly more found in children with SIBO compared with those without SIBO. CONCLUSIONS: SIBO is present in 14.3% of children presenting with AP-FGID. IBS, altered defecation pattern, loss of appetite, and belching were predictors for SIBO in children with AP-FGID.

Dientamoeba fragilis and chronic abdominal pain in children: a case-control study.

BACKGROUND: The association between Dientamoeba (D.) fragilis and the aetiology of functional gastrointestinal disorders (FGID) in children is unclear. AIM: The aim of this retrospective case-control study is to clarify the clinical relevance of D. fragilis in children with chronic abdominal pain. METHODS: From April 2011 until April 2013, a total of 132 patients with chronic abdominal pain (AP), aged 8-18 years, referred to a non-academic hospital, and 77 control patients, aged 8-18 years without gastrointestinal symptoms referred to a psychiatric hospital, were included in the study. D. fragilis was diagnosed by real-time PCR in faecal samples. Symptomatic children without a D. fragilis infection fulfilled the ROME III criteria for AP-related FGID (AP-FGID). Clinical data were retrospectively analysed by examining patients' hospital records from the Jeroen Bosch Hospital and Herlaarhof in The Netherlands. RESULTS: D. fragilis was detected in 57 patients with chronic AP (43.2%) and in 39 controls (50.6%) (p=0.255). No significant differences in symptomatology were found between D. fragilis-infected children and children fulfilling the criteria for AP-FGID. Parasitological eradication was achieved in 61.7% of patients after treatment with metronidazole or clioquinol, while clinical improvement occurred in only 40.4% of patients (p=0.435). CONCLUSIONS: There were no differences in symptoms comparing children with and without D fragilis infection. Furthermore, no relation was found between clinical and microbiological response after treatment for D. fragilis. This retrospective study suggests that there is no association between chronic AP and D. fragilis infection.

Probiotics for childhood functional gastrointestinal disorders: a systematic review and meta-analysis.

UNLABELLED: A systematic review and meta-analysis were performed to investigate the quantity and quality of the current evidence regarding the effect of different probiotic strains in the treatment of functional gastrointestinal disorders (FGID) in children and adolescents. CONCLUSION: Probiotics are more effective than placebo in the treatment of patients with abdominal pain-related FGID, especially with respect to patients with irritable bowel syndrome. To date, however, probiotics have not proved effective for children with functional constipation.

Doença celíaca é super-representada em pacientes com constipação / Celiac disease is overrepresented in patients with constipation

OBJETIVO: Tem sido sugerido que pacientes com constipação sejam triados para doença celíaca. Da mesma forma, recomenda-se a investigação desses pacientes para hipotiroidismo e hipercalcemia. Contudo, nenhuma evidência para essas recomendações está disponível até o momento. Assim, propusemos-nos determinar a prevalência de doença celíaca, hipotiroidismo e hipercalcemia em crianças com constipação. MÉTODOS: Estudo de coorte prospectivo com 370 pacientes consecutivos que preencheram os critérios de Roma III para constipação. Esses pacientes foram encaminhados por um clínico geral a um pediatra devido ao fracasso no tratamento com laxantes. RESULTADOS: A biópsia comprovou doença celíaca em sete desses pacientes. Isso é significativamente mais alto (p < 0,001) do que a prevalência de 1:198 de doença celíaca nos Países Baixos. Dois pacientes tinham tiroidite autoimune. Nenhum paciente tinha hipercalcemia. CONCLUSÕES: Conclui-se que a doença celíaca é significativamente super-representada em pacientes com constipação encaminhados por um clínico geral a um pediatra devido ao fracasso no tratamento com laxantes. Todos esses pacientes devem, portanto, ser triados para doença celíaca.

OBJECTIVE: It is suggested that patients with constipation should be screened for celiac disease. Similarly, it is recommended to investigate these patients for hypothyroidism and hypercalcemia. However, no evidence for these recommendations is available so far. We therefore set out to determine the prevalence of celiac disease, hypothyroidism, and hypercalcemia in children with constipation. METHODS: Prospective cohort study of 370 consecutive patients who met the Rome III criteria for constipation. These patients were referred by a general practitioner to a pediatrician because of failure of laxative treatment. RESULTS: Seven of these patients had biopsy-proven celiac disease. This is significantly higher (p < 0.001) than the 1:198 prevalence of celiac disease in the Netherlands. Two patients had auto-immune thyroiditis. No patient had hypercalcemia. CONCLUSIONS: We conclude that celiac disease is significantly overrepresented in patients with constipation who are referred by a general practitioner to a pediatrician because of failure of laxative treatment. All such patients should, therefore, be screened for celiac disease.

A pilot study of yoga treatment in children with functional abdominal pain and irritable bowel syndrome.

OBJECTIVES: The aim of this pilot study was to evaluate the effect of yoga exercises on pain frequency and intensity and on quality of life in children with functional abdominal pain. DESIGN: 20 children, aged 8-18 years, with irritable bowel syndrome (IBS) or functional abdominal pain (FAP) were enrolled and received 10 yoga lessons. Pain intensity and pain frequency were scored in a pain diary and quality of life was measured with the Kidscreen quality of life questionnaire (KQoL). RESULTS: In the 8-11 year old group and the 11-18 year old group pain frequency was significantly decreased at the end of therapy (p=0.031 and p=0.004) compared to baseline. In the 8-11 year group pain intensity was also significantly decreased at this time point (p=0.015). After 3 months there still was a significant decrease in pain frequency in the younger patient group (p=0.04) and a borderline significant decrease in pain frequency in the total group (p=0.052). Parents reported a significantly higher KQoL-score after yoga treatment. CONCLUSION: This pilot study suggests that yoga exercises are effective for children aged 8-18 years with FAP, resulting in significant reduction of pain intensity and frequency, especially in children of 8-11 years old.
