One of the most interesting features of our study is to identify a correlation between myelomeningocele, CH 4, delayed OCTT and UTI. The association between CH 4 and constipation suggests that CH 4 has an active role in the development of constipation. Interestingly, all myelomeningocele children who produced CH 4 showed a delayed OCTT and a higher incidence of UTI, with a lower frequency of evacuation, compared with those with a normal or accelerated OCTT. Moreover 44.4% (8/18) produced high levels of CH 4. Thirty-nine percent (7/18) of the children showed SIBO and 61% (11/18) presented a delayed OCTT. A nephro-urological clinical evaluation of the number of urinary tract infections (UTIs) and neurogenic bowel disease score were also performed. All patients performed a visual analog scale to investigate abdominal pain, bloating and flatulence, and maintained a diary of the frequency and consistency of the stool during the previous 7 days. All subjects underwent H 2/CH 4 lactulose breath tests to assess SIBO and OCTT. Methods:Įighteen (6M/12F 16.4☗.6 years) children affected by myelomeningocele were enrolled. This study was conducted at the Catholic University in Rome, Italy. Parkinsonism & related disorders, 54, 110-112.The objective of this study was to assess the prevalence of small intestinal bacterial overgrowth (SIBO), methane (CH 4) production and orocecal transit time (OCTT) in children affected by myelomeningocele.

Acknowledgement: Parkinson’s Foundation Translational Research Award. Methanogens may play a critical role in constipation and PD overall, however, further study is needed. There was no correlation between SIBO or IMO and the HY stage.Ĭonclusion: Our study reveals over half of PD subjects with constipation have IMO, which correlates with constipation severity. The maximum methane level during GBT also correlated with severity of constipation. There was good correlation between constipation and IMO, but not SIBO, Table 2. 52.6% (10/19) of PD subjects had IMO compared to 14.6% (23/158) subjects with unexplained GI symptoms (p<0.001). 31.6% (6/19) of PD subjects had SIBO versus 23.4% (37/158) of subjects with unexplained GI symptoms (p=0.95), shown in Table 1. Results: In this interim analysis, 19 patients with PD (68.2 ± 7.0 years, F/M=6/13) were enrolled and compared to 158 subjects with unexplained GI symptoms (47.4 ± 15.3 years, F/M=119/39). PD stage was assessed by Hahn-Yahr (HY) stage. Constipation was defined by <3 complete spontaneous bowel movements (CSBMs)/week. Daily bowel movements were assessed by prospective stool diary. SIBO was defined as H 2 rise of ≥20 ppm from baseline and/or CH4 rise of ≥10 ppm. ![]() ![]() Samples are collected in a bag (QuinTron Instrument Company, Inc.) and alveolar gas was analyzed for both H 2 and CH 4 levels by chromatography (QuinTron MicroAnalyzer, QuinTron, Inc). Breath samples were obtained at baseline and 15 min intervals for 2 h. During GBT, 75 g of glucose dissolved in 250 mL water was administered. Method: After an overnight fast and a day of low-CHO diet, subjects brushed their teeth and rinsed their mouth with antiseptic mouthwash 2h before test. Eradication of SIBO can improve motor fluctuations in PD 2. SIBO in PD has been associated with worse motor function and longer off time 2. Objective: Our aim is to quantify the prevalence of small intestinal bacterial overgrowth (SIBO) and intestinal methanogen overgrowth (IMO) in PD subjects with constipation compared to patients with unexplained GI symptoms undergoing glucose breath testing (GBT).īackground: Prevalence of SIBO varies widely in PD 1.
