J Pediatr Gastroenterol Nutr 1993; 17:239–46. 6. There were also no differences between the specimens obtained in endoscopic biopsies (distal duodenal) and those obtained at the same time using a Crosby capsule (jejunal). May; 31 (5):544-551 10.1002/humu.21224 [Google Scholar] The need for alternative treatment strategies is evident. Although myosin Vb is implicated in the organization of intracellular transport and cell surface … Phillips AD, Jenkins P, Raafat F, et al. Schofield DE, Agostini Jr RM Yunis EJ. Microvillus inclusion disease (MVID) is a disorder of intestinal epithelial differentiation characterized by life-threatening intractable diarrhea. Intestinal biopsies reveal extensive microvilli abnormalities, typical inclusions and vesicles mainly of the apical-luminal enterocytes and colonocytes. Oliva MM, Perman JA, Saavedra JM, et al. described eight infants with early-onset severe watery diarrhea associated to facial deformities and unusual tufts of woolly hair with trichorrhexis nodosa. A diagnosis of intractable diarrhea of infancy was made, and she was transferred to the Royal Hospital for Sick Children, where extensive investigations revealed no evidence of enteropathogens, disaccharidase deficiency, cystic fibrosis, pancreatic insufficiency, or immunodeficiency. Hum Mutat 2010. MVID can be diagnosed based on loss of microvilli, microvillus inclusions, and accumulation of subapical vesicles. 4) that suggest that there is an underlying continuing pathologic process. 4B). It was also noted that lateral membrane microvilli were readily found (Fig. The abnormal accumulation of PAS material in the tissue specimens of our patient was initially seen in the epithelial cells of the upper crypt. The disease was first described by … your express consent. Unfortunately, no colonic specimens were obtained before the episode of shock, and it is therefore unknown whether this was an improvement. Also called congenital or familial microvillous atrophy Disorder of intestinal brush border that causes intractable watery diarrhea with steatorrhea in infants Patients require total parental nutrition and rarely live beyond age 2 years Villous atrophy may be due to apoptotic cell loss (Hum Pathol 2000;31:1404) Microvillus inclusion disease prevents the absorption of nutrients from food during digestion, resulting in malnutrition and dehydration. MVID results in secretory diarrhea, brush border (BB) defects, villus atrophy, and … She subsequently thrived, stabilizing at the 25th percentile at 20 months and subsequently (Fig. Despite this, she continued to have secretory diarrhea, possibly relating to an abnormal sodium transport system (4). Her mother did not report significantly increased diarrhea, and a 3-day fat balance study revealed fat intake of 36 g/24 hr, and fecal fat output of 0.74 g/24 hr (absorption index, 98%), which confirmed that she did not have fat malabsorption. Subsequently, she was weaned onto a hydrolyzed protein formula (Pregestimil; Mead-Johnson, Hounslow, Middlesex, UK), which she tolerated well, and she was discharged home 4 weeks after admission. Whether environmental agents could cause this disease has not been explored, although experimental data have produced microvillous inclusions in the epithelium. By obtaining mucosal specimens from two sites at the same time, we found no regional differences in the abnormalities seen. Incidence of Gastroesophageal Reflux with Whey- and Casein-Based Formulas in Infants and in Children with Severe Neurological Impairment, Differential Diagnosis of Cyclic Vomiting Syndrome, Familial Microvillous Atrophy: A Clinicopathological Survey of 23 Cases, by European Society for Pediatric Gastroenterology, Hepatology, and Nutrition and North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition. Carruthers L, Phillips AD, Dourmashkin R, et al. How does cancer arise based on complexity theory? Because more of these children survive for longer periods (with improving management of PN) we believe that the use of early intestinal transplantation for the treatment of MVID should be reviewed. Further biopsies (both endoscopic and using Crosby capsule) were performed simultaneously 6 months after the patient's diet had been liberalized. Microvillus inclusion disease is inherited as an autosomal recessive genetic trait. Electron micrographs of original diagnostic specimens show (A) a microvillous inclusion (original magnification, ×20,000), (B) areas of virtual absence or disordered microvilli in the brush border (original magnification, ×4,500), (C) abnormal accumulation of secretory granules (original magnification, ×22,500), and (D) lateral membrane microvilli (original magnification, ×28,000). For more information, please refer to our Privacy Policy. The frequency of cytoplasmic inclusions has not previously been related to the clinical outcome; however, three cases labeled intestinal microvillous dystrophy in which no inclusions were seen all had a poor prognosis (8). Registered users can save articles, searches, and manage email alerts. Carruthers L, Dourmashkin R, Phillips A. Although diagnosis can be suspected by special stains of the mucosa (PAS, … The PAS-stained polysaccharides, glycoproteins, and glycolipids and the abnormal accumulation in the epithelial cells are thought to be due to abnormal localization of the brush border enzymes (6) and have been related to the presence of secretory granules (7). Am J Clin Pathol 1992; 98:119–24. Inflammatory disorders: autoimmune enteropathy Behçet disease Crohn's disease diaphragm disease duodenal peptic ulcer eosinophilic enteritis / gastroenteritis ileal pouch / pouchitis … By continuing to use this website you are giving consent to cookies being used. For immediate assistance, contact Customer Service: may email you for journal alerts and information, but is committed Other extensive investigations did not provide a clear diagnosis, and because of persisting diarrhea and weight loss, she needed 7 days of PN. In 1994, Girault et al. The microvillous inclusions were readily visible throughout the sections. Her pathologic findings at diagnosis were pathognomonic of the disease (3), and review of histology by experts in this disease confirmed the diagnosis. Other than central venous catheter infections and catheter changes, she remained in good health, although diarrhea continued unchanged at seven to eight loose stools per day. It is well recognized that there is variation in the clinical severity of MVID. This pathology leads to the characteristic intractable, life-threatening, watery diarrhea. Next is the possibility that the marked abnormalities seen in the original specimens were the consequence of an acquired disease yet to be described. Without adequate water and nutrients, children with this condition can become dehydrated, suffer from malnutrition, and fail … The case presented here illustrates the need for caution in considering early transplantation in children with late-occurring or clinically mild MVID. However Phillips et al. All registration fields are required. Microvillus inclusion disease is an intestinal disorder characterized by severe, watery diarrhea and an inability of the intestines to absorb nutrients. Thus, this case seems to have disparate data for the clinical and pathologic phenotypes. Background: Microvillous inclusion disease (MVID) is a rare congenital disease producing intractable secretory diarrhea in early infancy. Her clinical presentation was thus more in keeping with the late-onset group, and the disease was clearly at the mild end of the spectrum. Your account has been temporarily locked due to incorrect sign in attempts and will be automatically unlocked in 800-638-3030 (within USA), 301-223-2300 (international). She subsequently had reasonable weight gain along the 10th percentile, reportedly passing two to three seedy stools per day until 3 months of age, when she was admitted with fever, vomiting, and recurrence of green watery stools (six to eight stools per day). Electron micrographs of recent specimens. 1B). 800-638-3030 (within USA), 301-223-2300 (international) In the more common early-onset form, affected patients … Cutz E, Sherman PM, Davidson GP. Lifelong parenteral nutrition (PN) is necessary from diagnosis, and the outlook is poor. Successful intestinal transplantation for microvillus inclusion disease. 124 POSTVIRAL GASTROPARESIS IN CHILDREN: PRESENTATION, TREATMENT AND OUTCOME. Enteropathies associated with protracted diarrhoea of infancy: Clinicopathological features, cellular and molecular mechanisms. Get new journal Tables of Contents sent right to your email inbox, August 2000 - Volume 31 - Issue 2 - p 185-189, Microvillous Inclusion Disease: An Evolving Condition, Articles in Google Scholar by Nicholas M. Croft, Other articles in this journal by Nicholas M. Croft. Data is temporarily unavailable. It has been suggested that MVID is a congenital abnormality of a transport mechanism in the exocytosis of brush border–related material (10). It is characterized by the neonatal onset of abundant watery diarrhea persisting despite total bowel rest. Microvillus inclusion disease (also referred to as congenital microvillus atrophy) is, with Tuft enteropathy, the best known disease of the intestinal epithelium causing intractable diarrhea of infancy, and a leading cause of secretory diarrhea in the first weeks of life. Journal of Pediatric Gastroenterology and Nutrition : Periodic acid–Schiff (PAS) staining of the original and recent biopsy specimens. Inactivating mutations in MYO5Bcauses depolarization of enterocytes in the small intestine, which gives rise to chronic, unremitting secretory diarrhea. In those with late-onset disease, changes were first noted in the low villus epithelium. It is characterized by diffuse intestinal villous atrophy with no inflammatory reaction. The dramatic improvement in the PAS-stained specimens and the reduced (but persisting) abnormalities in the samples examined by electron microscopy, allied with her ability to thrive on an unrestricted enteral diet are, as far as we are aware, unique. Microvillus inclusion disease (MVID) is a rare autosomal recessive disorder due to defective apical surface of the enterocytes presenting with protracted diarrhea from birth. Hum Pathol 1994; 25:1243–8. The remaining 4 occurred between 6 and 9 weeks and were described as late onset. Despite clinical and pathologic improvement, this child continues to pass loose stools six to eight times per day, and abnormalities persist in the intestinal biopsy specimens (Fig. After this, PN was gradually discontinued. She was admitted at the age of 12 days to the local hospital with drowsiness, vomiting, weight loss (from the 50th to the 10th percentile) and a 1-day history of watery green diarrhea. At the age of 3.3 years, after we held a discussion with her parents, because of her general good health and increasing interaction with other children at a nursery, the patient's diet was liberalized to allow her to eat freely. A girl weighing 3.51 kg was born at term to nonconsanguineous parents and received cow's milk formula from birth. Weight chart of the patient from the age of 2 years shows rapid increase in weight after the introduction of an unrestricted diet and continuing weight gain after the cessation of parenteral nutrition. The oldest was then 5 years of age, and two tolerated some oral feeding, but all needed PN. This case and the review by Phillips and Schmitz (1) suggest that the presence of lateral membrane microvilli detected by electron microscopy can be related to a mild clinical phenotype. Arch Dis Child 1985; 60:135–40. Stool electrolytes at this time showed a secretory pattern (108 mmol/L sodium, 11.9 mmol/L potassium, 55 mmol/L chloride and 330 mOsm/kg osmolality). Onset most often occurs within the first days of life. Her weight had increased by 500 g, and she was passing three seedy stools per day. N2 - Microvillus inclusion disease (MID) is a rare neonatal enteropathy that is typically diagnosed using electron microscopy to show characteristic inclusions in conjunction with light microscopy and periodic acid-Schiff staining to show lack of the normal brush border on biopsies obtained endoscopically from the small bowel. Intractable diarrhoea in infancy: a continuing challenge for the paediatric gastroenterologist. revised March 20, 2000; accepted March 21, 2000. Serum ferritin, folate, vitamin B12, and red cell folate levels were all within the normal range. 3) suggesting that she was absorbing significant energy and nutrients enterally. Affected infants often have difficulty gaining weight and growing at the expected rate (failure to thrive), developmental delay, liver and kidney problems, and thinning of the bones (osteoporosis). MVID is caused by mutations in the MYO5B gene, coding for the myosin Vb motor protein. In Phillips' series this was found to be consistent with the severe congenital group. Clin Gastroenterol 1986; 15:105–20. 2B); and epithelial cells with abnormal accumulation of secretory granules (Fig. Inherited MYO5B mutations have recently been associated with microvillus inclusion disease (MVID), an autosomal recessive syndrome characterized by intractable, life-threatening, watery diarrhea appearing shortly after birth. Microvillus inclusions: intracellular vesicle-like structures that are internally (luminally) lined by microvilli, characteristic of microvillus inclusion disease. The first possibility is related to the genetic basis of the disease. Pavelka M, Gangl A. Microvillus inclusion disease (MVID ) is a congenital enteropathy characterized by loss of apical microvilli and formation of cytoplasmic inclusions lined by microvilli in enterocytes. We report a child with MVID who, at the age of 5 years, is thriving on a normal unrestricted diet and in whom the most recent small bowel biopsy specimens showed pathologic abnormalities significantly less marked than those found at diagnosis. Follow Dr. Pernick's blog by clicking, 30100 Telegraph Road, Suite 408, Bingham Farms, Michigan 48025 (USA). The jejunal mucosa showed partial villous atrophy and foci of enterocyte cytoplasmic vacuolation most prominent at the apices of villi. She had no evidence of significant liver or cardiopulmonary disease. 5. Microvillous inclusion disease (MVID) or microvillous atrophy (MVA) is a congenital and constitutive disorder of intestinal epithelial cells [ 1 – 6 ]. Wolters Kluwer Health However the presence of a larger number of lateral membrane microvilli in this case, both at diagnosis and in later specimens, is consistent with the findings in the less severe late-onset group reported by Phillips and Schmitz (1). 2C). The diagnosis of microvillus inclusion disease was established by documentation of microvillus inclusions in duodenal epithelial cells. (A) Staining (original magnification, × 100) of the original diagnostic specimens in the patient aged 3 months. Walker-Smith JA. We had expected that the features originally identified would persist largely unchanged. Microvillus inclusion disease (MVID) is a rare inherited and invariably fatal enteropathy, characterized by severe intractable secretory diarrhea and nutrient malabsorption.

MICROVILLOUS INCLUSION DISEASE (MICROVILLOUS ATROPHY) Frank M Ruemmele, Jacques Schmitz & Olivier Goulet Orphanet Journal Of Rare Disease 2006, 1:22 2. Pediatr Pathol Lab Med 1997; 17:335–67. This confirmed that any changes between the original diagnostic specimens (obtained by Crosby capsule) and the more recent specimens (obtained endoscopically) were not due to the method of sampling. A technique using alkaline phosphatase histochemistry on routine sections of four jejunal biopsy specimens and one necropsy sample was applied to show that alkaline phosphatase activity, normally present in the brush border, occurs in the enterocytes of patients with microvillus inclusion disease. There are three possible ways in which this improvement may have occurred. Raafat F, Green NJ, Nathavitharana KA, et al. Gastrointestinal microvillus inclusion disease. Registered users can save articles, searches, and manage email alerts. Intestinal microvillous dystrophy: a variant of microvillous inclusion disease or a new entity? Stools, blood, swabs, and urine examination did not reveal any pathogens. Please try after some time. Lateral membrane microvilli continued to be found but less frequently than in the original set of biopsy specimens (Fig. J Pediatr Gastroenterol Nutr 1985; 4:902–7. In vitro, this has been shown in organ culture of fetal intestinal epithelium exposed to cytochalasin, which disrupts microfilaments by binding to their elongation ends (7). 12. This website is intended for pathologists and laboratory personnel but not for patients. Although the appearance of the small bowel specimens were unchanged before and after this episode, colonic mucosa collected afterward was normal. Clinical presentation with secretory diarrhea in the first week of life is typical, with massive stools and electrolyte loss even when no enteral nutrition is … Two days after admission, spontaneous bleeding into the left hip and buttock occurred, and coagulopathy was identified and corrected with fresh-frozen plasma and vitamin K.
