Small intestinal bacterial overgrowth (SIBO) is associated with chronic gastrointestinal diseases and structural/functional abnormalities of the gastrointestinal tract. SIBO’s association with clinical characteristics is unclear. This study investigates the association between clinical factors and SIBO according to lactulose hydrogen breath test (LHBT) result.Methods. A cross-sectional study in a university-based gastroenterology practice was performed. Data was abstracted from the medical records of subjects undergoing LHBT from 6/1/2009 to 6/1/2013. Logistic regression analysis was performed to determine the association between predictor variables: age, sex, body mass index (BMI), and positive LHBT, the outcome of interest.Results. LHBT was performed in 791 subjects. Fifty-four percent had a positive LHBT. There was no statistically significant difference between the LHBT results according to age or BMI. In females, the likelihood of a positive LHBT increased with age (OR 1.02; 95% CI: 1.01–1.03). In males, the likelihood of a positive LHBT result decreased with age (OR 0.98; 95% CI: 0.97–1.00).Conclusion. There was an association between age, with respect to sex, and a positive LHBT. With increased age in females, the odds of a positive LHBT increased, while, in men, the odds of a positive LHBT decreased with age.

Serotonin Pathway

Small intestinal bacterial overgrowth (SIBO) is a condition associated with diverse clinical conditions and there is no gold standard in its diagnosis and treatment. Tryptophan (Trp) metabolism may be involved in etiology of gastrointestinal diseases and is regulated by intestinal microbiota. In our study we investigated aspects of the serotonin (5-HT) pathway of Trp metabolism in three groups of individuals based on the hydrogen concentration in the lactulose hydrogen breath test (LHBT): controls (<20 ppm) and SIBO patients (≥20 ppm), with diarrhea (SIBO-D) or constipation (SIBO-C). The SIBO-D patients showed an increased serum concentration of 5-HT and small intestinal mucosa mRNA expression of tryptophan hydroxylase 1 (TPH-1), a rate-limiting enzyme in 5-HT biosynthesis. Urinary 5-hydroxyindoleacetic acid (5-HIAA), the main metabolite of 5-HT, was higher in both group of SIBO patients than controls. A positive correlation between 5-HIAA and LHBT was observed. A two-week treatment with rifaximin decreased hydrogen in LHBT and 5-HIAA concentration in SIBO patients. In conclusion, the serotonin pathway of Trp metabolism may play a role in the pathogenesis of hydrogen-positive SIBO and it may influence the diversification of SIBO into variants with diarrhea or constipation. As urinary 5-HIAA concentration correlates with LHBT, TPH-1 expression in colonic mucosa and TH-5 in serum of SIBO patients, it can be considered as a non-invasive marker of this condition.

Background : Fibromyalgia syndrome (FMS) is defined as widespread and persistent pain in the musculoskeletal system. There are limited reports regarding the prevalence of fibromyalgia syndrome in patients with advanced kidney failure undergoing regular hemodialysis. Therefore, this study aimed to evaluate the prevalence of fibromyalgia syndrome and its risk factors in a large proportion of patients under the hemodialysis condition. Materials and Methods: In this cross-sectional study, 293 patients who were admitted to the hemodialysis ward were evaluated for fibromyalgia syndrome in an educational hospital. The questionnaire was designed according to symptom severity score (SS score) and widespread pain index (WPI) criteria. The correlation between FMS and various variables, including demographic, clinical, and biochemistry biomarkers, was also precisely calculated by logistic regression. Data were analyzed using SPSS v.17 statistics software. Results: The results showed that, of 293 hemodialysis patients, 130 patients (44.4%) had fibromyalgia, the mean age of patients with and without fibromyalgia was 61.09 ± 15.36 and 53.49 ± 15.38 years old, respectively (P = 0.001). Moreover, there was a significant difference in terms of gender among patients with fibromyalgia syndrome (P = 0.001). To note, there was no significant relationship between the kidney failure etiopathogenesis, duration of dialysis, body mass index (BMI), Kt/v index, history of peritoneal dialysis, and laboratory parameters with fibromyalgia in hemodialysis patients (P > 0.05). However, our findings revealed that both age and gender could be considered as the predictor variables associated with fibromyalgia in patients undergoing hemodialysis. Conclusion: Taken together, in this study, we found that age and gender would be the critical factors in terms of the fibromyalgia syndrome in patients undergoing hemodialysis.

Abstract Aim To determine signs and symptoms associated with teething, parental beliefs about teething, and the effects of socioeconomic status on teething in Nigerian children. Methods and Materials A cross-sectional study consisting of 1,013 mothers of children between the ages four to 36 months who visited the immunization clinics at the Community Health Centres in Ife Central and Ife East Local Government Areas. Data was analyzed using STATA (Intercooled release 9) for Windows. Results A total of 765 mothers (75.5%) reported systemic signs and symptoms in their children. Fever (51.8%), diarrhea (12.5%), and vomiting (2.9%) were the most prevalent symptoms and signs reported. Teething problems were reported by 60% of mothers from a high socioeconomic class, as well as 76.7% and 77.9% from middle and low socioeconomic classes, respectively. Interestingly, 65.5% of mothers believed teething should be accompanied with systemic signs and symptoms such as fever (42.1%), diarrhea (13.9%), and vomiting (0.6%). No significant difference was noted between breastfeeding status, gender of the child, and reported systemic signs and symptoms noticed by the mothers. Conclusion Most mothers in the study reported signs and symptoms adduced to teething in their children irrespective of their beliefs. Fever ranked highest of the signs and symptoms reported. Mothers of children from the high socioeconomic class reported fewer teething symptoms. Breastfeeding status and gender of the child had no effect on teething problems in the children studied. Clinical Significance Most signs and symptoms adduced to teething by parents may actually be due to underlying infections. Thus, there is a need to rule out occult infection during the tooth eruption period. Citation Oziegbe EO, Folayan MO, Adekoya-Sofowora CA, Esan TA, Owotade FJ.
