Familial hepatic venoocclusive disease with probable immune deficiency
Insights
Five infants experienced fatal veno-occlusive liver disease, suggesting a congenital cause linked to immune deficiency. This rare condition highlights potential genetic factors in infant liver disease.
Area of Science:
- Pediatrics
- Immunology
- Hepatology
Background:
- Veno-occlusive disease of the liver (VOD) is a serious condition affecting infants.
- Etiology of VOD is often multifactorial, including genetic, toxic, and infectious causes.
Observation:
- Five infants from three families presented with fatal VOD between 2 and 7 months of age.
- No extrinsic causes like diet or toxins were identified.
- Consanguineous parents in two families suggest a possible genetic link.
Findings:
- All affected infants exhibited signs of immune deficiency, including hypogammaglobulinemia.
- Recurrent infections (Pneumocystis carinii, enteroviruses) and abnormal lymphoid tissues were noted.
- Associated findings included microcephaly, cerebral softening, and endocardial fibrosis.
Implications:
- The findings suggest a potential congenital or genetic etiology for VOD in these cases.
- Further research into genetic factors and immune system development in VOD is warranted.
- Early identification of immune deficiencies may aid in managing infants at risk for VOD.
Abstract:
Five infants from three families died between the ages of 2 and 7 months with venocclusive disease of the liver. No dietary, toxic, or other extrinsic cause was uncovered. In one family the first infant was breast-fed; the second one received no breast milk. In two of the families the parents were cousins. All infants had some evidence of immune deficiency, including hypogammaglobulinemia in at least three, multiple infections especially Pnumocystis carnii and enteroviruses, and lymphoid tissues devoid of germinal centers and mature plasma cells. Other findings in some of the infants, not previously recorded in venoocclusive disease, were microcephaly, multiple small cerebral softening, and left atrial endocardial fibrosis. A congenital cause for venoocclusive disease is suggested in these cases.
