Microvillous inclusion disease, also known as Davidson's disease, congenital microvillous atrophy and, less specifically, microvillous atrophy, is a rare genetic disorder of the small intestine that is inherited in an autosomal recessive pattern.[1][2]
Presentation
It is characterized by chronic, intractable diarrhoea in new-born infants, starting in the first few days of life.[3]
Prognosis
It is nearly always fatal unless, like short bowel syndrome patients, treated with parenteral nutrition or an intestinal transplant.[3] The patient is often classified as being in "intestinal failure" and treated with the cohort of patients known as "short bowel syndrome" patients.
Pathophysiology
It is caused by a congenital lack of apical microvilli in the epithelial cells of the small intestine.[4]
Diagnosis
Diagnosis in utero is currently not possible as the gene(s) involved in the disease are not known;[5] diagnosis is made by biopsy of the small intestine.[1]
Biopsy
The appearance of microvillous inclusion disease on light microscopy is similar to celiac sprue; however, it usually lacks the intraepithelial lymphocytic infiltration characteristic of celiac sprue and stains positive for carcinoembryonic antigen (CEA).[2] The definitive diagnosis is dependent on electron microscopy.[6]
Differential diagnosis
The differential diagnosis of chronic and intractable diarrhea is:[5]
- Intestinal epithelial dysplasia
- Syndromatic diarrhea
- Immunoinflammatory enteropathy
Genetic prevalence
Microvillous inclusion disease is thought to be extremely rare; only, approximately, two dozen cases have been identified in the medical literature.[7]
History
Microvillous inclusion disease was first described in 1978 by Davidson et al.[8] It was originally described as familial enteropathy.
