Anti-PD1-/PDL1-induced chronic intestinalpseudo-obstruction: three cases treated with vedolizumab after corticosteroid failure with mixed results. Immune checkpoint inhibitors (ICI), i.e., anti-PD1/PDL1 and anti-CTLA-4, have reshaped the prognosis of many cancers. Increased use of ICI has led to the onset of new adverse events. Neurological immune-related adverse events are rare, heterogenous , and potentially life-threatening. Chronic intestinalpseudo-obstruction (CIPO) is an immune-related autonomic plexus neuropathy that may be caused by infiltration of the myenteric plexus by CD8 + T cells. It is a rare and potentially fatal side effect that can be difficult to diagnose early because of initial nonspecific clinical presentation including vomiting, nausea, diarrhea, and constipation. Some rare
Efficacy and safety of rifaximin in patients with chronic intestinalpseudo-obstruction: a randomized, double-blind, placebo-controlled, phase II-a exploratory trial. Chronic intestinalpseudo-obstruction (CIPO) is a rare intractable disease with limited treatment options. Small intestinal bacterial overgrowth (SIBO) often co-occurs with several diseases, including CIPO. While rifaximin (RFX
Glutamine supplementation as a novel metabolic therapeutic strategy for LIG3-dependent chronic intestinalpseudo-obstruction. We recently identified a recessive syndrome due to LIG3 mutations in patients with chronic intestinalpseudo-obstruction, leukoencephalopathy and neurogenic bladder. LIG3 mutations affect mitochondrial DNA (mtDNA) maintenance, leading to defective energy production. We

Multicenter, national, retrospective
Small-bowel transit scintigraphy in children with paediatric intestinalpseudo-obstruction. evidence of small intestinal dysmotility is a key criterion for the diagnosis of paediatric intestinalpseudo-obstruction (PIPO). Small bowel scintigraphy (SBS) allows for objective measurement of small bowel transit (SBT), but limited data is available in children. We aimed to evaluate the utility of SBS
Acute intestinalpseudo-obstruction secondary to Sjogren's syndrome in pregnancy: a case report and literature review. Intestinalpseudo-obstruction (IPO) is a rare disease, and its clinical manifestations can resemble mechanical intestinal obstruction leading to unnecessary and potentially harmful surgery. Certain autoimmune diseases have been associated with IPO, however, cases secondary
"Clinical utility of ileal motility in children with defecation disorders and children with chronic intestinalpseudo-obstruction". Little is known about ileal motility patterns and their utility in children. Here, we present our experience with children undergoing ileal manometry (IM). A retrospective review of children with ileostomy comparing IM between two groups: A (chronic intestinalpseudo-obstruction [CIPO]) and B (feasibility of ileostomy closure in children with defecation disorders). We also compared the IM findings with those from antroduodenal manometry (ADM), and evaluated the joint effect of age, sex, and study indication group on IM results. A total of 27 children (median age 5.8 years old, range 0.5 to 16.74 years, 16 were female) were included (12 in group A and 15
Pediatric intestinalpseudo-obstruction: An international survey on diagnostic and management strategies in the European Reference Network for rare Inherited and Congenital Anomalies intestinal failure teams. Pediatric intestinalpseudo-obstruction (PIPO) management is based on nutritional, medical and surgical care while available evidence is scarce. The aim of this study was to outline
LPAR1 regulates enteric nervous system function through glial signaling and contributes to chronic intestinalpseudo-obstruction. Gastrointestinal motility disorders involve alterations to the structure and/or function of the enteric nervous system (ENS) but the causal mechanisms remain unresolved in most cases. Homeostasis and disease in the ENS are processes that are regulated by enteric glia with chronic intestinalpseudo-obstruction (CIPO), a severe motility disorder, showed reduced glial LPAR1 expression in the colon and ileum. These data suggest that enteric glial LPAR1 signaling regulates gastrointestinal motility through enteric glia and could contribute to severe motility disorders in humans such as CIPO.
Twenty Years of Gut Transplantation for Chronic IntestinalPseudo-obstruction: Technical Innovation, Long-term Outcome, Quality of Life, and Disease Recurrence. To define long-term outcome, predictors of survival, and risk of disease recurrence after gut transplantation (GT) in patients with chronic intestinalpseudo-obstruction (CIPO). GT has been increasingly used to rescue patients with CIPO
Pediatric IntestinalPseudo-Obstruction: Impact of Neonatal and Later Onset on Clinical and Nutritional Outcomes. The aim of the study was to evaluate long-term nutritional outcomes and clinical characteristics in a cohort of children with pediatric intestinalpseudo-obstruction (PIPO) at neonatal-onset (NO-PIPO) and at later-onset (LO-PIPO). All children fulfilling new PIPO criteria over a 30
Chronic intestinalpseudo-obstruction with pneumatosis cystoides intestinalis in a patient with systemic sclerosis: A case report. Chronic intestinalpseudo-obstruction (CIPO) and pneumatosis cystoides intestinalis (PCI) are rare abdominal diseases and the pathological mechanisms have not been fully elucidated. Systemic sclerosis (SSc), which is characterized by the progressive sclerotic changes
Lupus intestinalpseudo-obstruction and hydronephrosis: Case report. Intestinalpseudo-obstruction (IPO) is a rare and life-threatening complication of lupus. A patient with long-standing lupus developed recurrent abdominal pain and distension as well as nausea and emesis. Imaging showed dilated small bowel loops with air-fluid levels and bowel wall thickening. She also had bilateral hydronephrosis. She was given high-doses of intravenous steroids and cyclophosphamide. Her symptoms resolved within a week of starting immunosuppression. She was eventually transitioned to mycophenolate mofetil. She remained in remission and immunosuppression was successfully stopped after 1 year. Intestinalpseudo-obstruction is a rare complication of lupus that is often seen in association
The Use of Pyridostigmine in a Child With Chronic IntestinalPseudo-Obstruction. Chronic intestinalpseudo-obstruction is a rare disorder that affects the motility of the gastrointestinal tract. It results in acute or subacute intestinal obstruction symptoms in the absence of mechanical lesion. It can lead to intestinal failure in children with significant strain on nutrition, growth , and development. There is no universally agreed protocol for management of chronic intestinalpseudo-obstruction in children, and there is wide variation in clinical practice.
Intestinalpseudo-obstruction as the initial manifestation of systemic lupus erythematosus. Small bowel obstruction is common in emergency departments. However, the exact cause of intestinalpseudo-obstruction (IPO) is often misdiagnosed. IPO is considered a severe manifestation of systemic lupus erythematosus (SLE). However, IPO is rare as the initial manifestation of SLE. This paper reports
The chronic intestinalpseudo-obstruction subtype has prognostic significance in patients with severe gastrointestinal dysmotility related intestinal failure. Severe gastrointestinal dysmotility (GID) is a significant cause of chronic intestinal failure (CIF) with unclear benefits of sub-classifying into Chronic IntestinalPseudo-obstruction (CIPO) and non-CIPO sub-types. We compared outcomes
