BACKGROUND: Observational studies have shown a link between constipation (CN) and psychiatric disorders, including Schizophrenia (SP), Bipolar disorder (BD), Schizoaffective disorder (SD), and Parkinson's disease (PD). However, it is still unknown whether CN affects the occurrence and development of psychiatric disorders or whether psychiatric disorders cause the occurrence and development of CN. Therefore, this study used Mendelian randomization (MR) analysis to evaluate the relationship between CN and psychiatric disorders. METHOD: We used genome-wide association studies (GWAS) to assess the relationship between constipation (N = 411, 623) and four psychiatric disorders, including SP ( N = 77, 096), BD (N = 51, 710), SD ( N = 210, 962), PD (N = 482, 730 ), using bidirectional MR analysis. Inverse variance weighting (IVW), MR Egger (ME) and Weighted median (WM) were used as causal analysis methods. Cochran's Q test, funnel plot, MR Egger intercept test and Leave.one.out analysis were used to detect sensitivity. Confounding factors were analyzed and eliminated by LDtrait to avoid influencing the final MR Analysis result. RESULTS: The results of positive MR analysis indicated that there was no evidence of influence of constipation on SP (OR 1.043, 95%CI 0.946 - 1.149, P value = 0.398), BD (OR 1.114, 95%CI 0.995 - 1.248, P value = 0.062), SD (OR 0.934, 95%CI 0.674 - 1.294, P value = 0.682) and PD (OR 1.118, 95%CI 0.918 - 1.361, P value = 0.269) under gene prediction. Reverse MR analysis suggested that SP (OR 1.030, 95% CI 1.001-1.060, P value = 0.042) had a causal relationship with constipation. BD (OR 0.993, 95% CI 0.962-1.025, P value = 0.664), SD (OR 1.021, 95% CI 0.984-1.059, P value = 0.265) and PD (OR 1.004, 95% CI 0.974-1.035, P value = 0.790) were not associated with CN. CONCLUSION: There was a positive association between SP and CN. CN may have no exact causal relationship with BD, SD and PD, and the interaction mechanism between these diseases needs to be further explored.
OBJECTIVE: To evaluate the prevalence and clinical consequences of gastro-intestinal manifestations in Maternally Inherited Diabetes and Deafness syndrome (MIDD). METHODS: We report the case of fatal intestinal pseudo-obstruction in a patient with severe MIDD. Using a standardized questionnaire, we evaluate the frequency of gastrointestinal tract (GIT) symptoms in 10 patients with MIDD (8 A3243G and 2 T14709C mutations of mitochondrial DNA). The reference population consisted of 50 patients with type 1 diabetes matched for disease duration. In 4 patients with digestive manifestations endoscopic examination of upper and lower GIT was performed allowing multiple biopsies for ultrastructural and molecular analysis. RESULTS: GIT symptoms were frequently reported in MIDD specially in patients bearing the mt 3243 mutation. The manifestations i.e. constipation, diarrhea or both, were more frequent in this subgroup than in type 1 diabetic population (88% vs 28%, p<0.05). Ileus is a rare and severe complication with a frequent fatal Issue. Ultrastructural analysis of the mucosa from oesophagus, stomach, duodenum, colon and rectum showed mild modifications such as accumulation of normal mitochondria and lipId droplets. Heteroplasmy levels were determined in 4 patients harboring the 3243 mutation. In three patients the percentage of mutated DNA increased from upper to lower GIT. CONCLUSIONS: Gastrointestinal symptoms are frequent in MIDD secondary to 3243 mutation. They might explain the lower body weight observed in these patients in comparison to reference diabetic populations. They can also lead to a severe complication namely the intestinal pseudo-obstruction.
OBJECTIVE: Idiopathic slow-transit constipation (STC) has been suggested to be a pangastrointestinal motility disorder. We investigated scintigraphically whether motility in the gallbladder and stomach was impaired in slow-transit constipation. METHODS: Twenty-four patients with STC were studied. Colon transit time, gallbladder motility, and solid-phase gastric emptying were measured by scintigraphy. RESULTS: Gallbladder dysmotility was observed in 8 of 18 (44.4%) patients. Mean gallbladder ejection fraction was 41.6 +/- 13.6% (range, 16.3-67.0%). Gastric emptying was delayed in 9 of 18 (50%) patients. Mean solid-phase gastric half-emptying time was 75 minutes. STC may be associated with impaired function of other gastrointestinal organs. Approximately half of patients with STC presented gallbladder or gastric dysmotility. CONCLUSION: STC may not be a pure colonic abnormality; it may be a component of a pangastrointestinal tract motility disorder involving several organs.
