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]

Contents

[edit] Presentation

It is characterized by chronic, intractable diarrhoea in new-born infants, starting in the first few days of life.[3]

[edit] 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.

[edit] Pathophysiology

It is caused by a congenital lack of apical microvilli in the epithelial cells of the small intestine.[4]

[edit] 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]

[edit] 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]

[edit] Differential diagnosis

The differential diagnosis of chronic and intractable diarrhea is:[5]

  • Intestinal epithelial dysplasia
  • Syndromatic diarrhea
  • Immunoinflammatory enteropathy

[edit] Genetic prevalence

Microvillous inclusion disease has an autosomal recessive pattern of inheritance.
Microvillous inclusion disease has an autosomal recessive pattern of inheritance.

Microvillous inclusion disease is thought to be extremely rare; only, approximately, two dozen cases have been identified in the medical literature.[7]

[edit] History

Microvillous inclusion disease was first described in 1978 by Davidson et al.[8] It was originally described as familial enteropathy.
