A case of severe malnutrition infant with neonatal onset intractable diarrhea.

ABSTRACT: BACKGROUND:Congenital tufting enteropathy (CTE) is a rare disease that manifests as intractable diarrhea during the neonatal period which is associated with mutations of the epithelial cell adhesion molecule (EpCAM) gene. CASE PRESENTATION:A male infant who presented with vomiting, diarrhea, abdominal distention, malnutrition and growth failure was admitted to our department when he was 2 months old. His parents were healthy and nonconsanguineous. Etiologic examinations of stool, inflammatory markers, blood gas and electrolytes levels, serum albumin level, serum immunoglobin levels were all normal. And there was no indication for metabolic diseases. Additionally, gastrointestinal contrast did not reveal abnormality of gastrointestinal. The patient was diagnosed with intestinal malabsorptive syndrome and severe malnutrition without definite cause. He was on supportive treatment and nutritional therapy for 13?months. However, he did not gain weight obviously. He was discharged at the age of 15?months and was fed with partial hydrolyzed formula and rice paste at home. Three months later he developed hypoglycemia and severe respiratory infection. Finally, he died due to sepsis and multiple organs failure. The next generation sequencing revealed one homozygous mutation of EpCAM gene and one complex heterozygous mutation of TTC7A gene. He was diagnosed CTE according to the genetic results and clinical manifestations. CONCLUSIONS:CTE is rarely reported in Asia. Patients present with congenital diarrhea, poor weight gain and growth failure are recommended to perform endoscopy examination with proper immunohistochemistry study as early as possible, and genetic testing is necessary when suspecting congenital diarrhea and enteropathy.

Project description:BACKGROUND:Patients with end-stage kidney disease (ESKD) most commonly complain of gastrointestinal symptoms, such as diarrhea. Diarrhea negatively affects patient quality of life and has miscellaneous etiologies, such as Clostridium difficile-associated diarrhea (CDAD) and ischemic colitis. However, it is sometimes extremely difficult to determine the true etiology given the comorbidities and complications the patients have. A rare cause of diarrhea is ulcerative colitis (UC), which commonly affects the rectum and proximal colon in a continuous fashion. UC with rectal sparing or segmental distribution, although atypical, sometimes leads to misdiagnosis. Herein, we present a case of UC in a patient on hemodialysis with intractable diarrhea; we initially considered that the diarrhea was caused by CDAD and ischemic colitis. CASE PRESENTATION:A 69-year-old man with a history of hypertension, bilateral thalamic hemorrhage, and decreased kidney function was admitted to our hospital because of congestive heart failure. Volume control was impossible due to renal dysfunction and he was started on hemodialysis. Thereafter, he received various antibiotics for bacterial infections. Simultaneously, he experienced continuous watery, and sometimes bloody, diarrhea, which was diagnosed as CDAD owing to a positive stool test for Clostridium difficile toxins. Antibiotic treatment for CDAD did not result in symptom relief. Subsequently, we performed colon biopsy via colonoscopy, and the pathology showed virtually no inflammation with rectal sparing and segmental distributions. These findings favored the presence of ischemic colitis due to arteriosclerosis and ESKD rather than infections. He died of cardiac arrest before the diarrhea was alleviated. Finally, UC was revealed on autopsy as the main cause of the uncontrollable diarrhea. CONCLUSIONS:Patients with ESKD have a greater risk of developing CDAD and ischemic colitis, which have clinical features that sometimes overlap with those of UC, as in the present case. This case emphasizes the importance of correctly diagnosing the etiology of intractable diarrhea and the fact that other diarrhea etiologies can obscure the existence of inflammatory bowel disease, which should be considered and treated properly when patients on hemodialysis present with intractable diarrhea.

Project description:BackgroundEnvironmental enteric dysfunction (EED) is widespread throughout the tropics and in children is associated with stunting and other adverse health outcomes. One of the hallmarks of EED is villus damage. In children with severe acute malnutrition (SAM) the severity of enteropathy is greater and short term mortality is high, but the metabolic consequences of enteropathy are unknown. Here, we characterize the urinary metabolic alterations associated with villus health, classic enteropathy biomarkers and anthropometric measurements in severely malnourished children in Zambia.Methods/principal findingsWe analysed 20 hospitalised children with acute malnutrition aged 6 to 23 months in Zambia. Small intestinal biopsies were assessed histologically (n = 15), anthropometric and gut function measurements were collected and the metabolic phenotypes were characterized by 1H nuclear magnetic resonance (NMR) spectroscopy. Endoscopy could not be performed on community controls children. Growth parameters were inversely correlated with enteropathy biomarkers (p = 0.011) and parameters of villus health were inversely correlated with translocation and permeability biomarkers (p = 0.000 and p = 0.015). Shorter villus height was associated with reduced abundance of metabolites related to gut microbial metabolism, energy and muscle metabolism (p = 0.034). Villus blunting was also related to increased sucrose excretion (p = 0.013).Conclusions/significanceIntestinal villus blunting is associated with several metabolic perturbations in hospitalized children with severe undernutrition. Such alterations include altered muscle metabolism, reinforcing the link between EED and growth faltering, and a disruption in the biochemical exchange between the gut microbiota and host. These findings extend our understanding on the downstream consequences of villus blunting and provide novel non-invasive biomarkers of enteropathy dysfunction. The major limitations of this study are the lack of comparative control group and gut microbiota characterization.
