Hemolytic uremic syndrome in 3 siblings
Clinical Nephrology
|July 1, 1984
Insights
A rare familial hemolytic uremic syndrome (HUS) affected three female infants in one family. Genetic predisposition is likely, necessitating consideration in genetic counseling for similar cases.
Area of Science:
- Pediatrics
- Genetics
- Nephrology
Background:
- Hemolytic uremic syndrome (HUS) is a serious condition often associated with gastrointestinal infections.
- Familial forms of HUS suggest underlying genetic factors influencing disease susceptibility or presentation.
Observation:
- Three female infants within a single family presented with HUS at similar ages (11.5, 12, and 16 months).
- The disease onset was gradual, with progressive deterioration, prolonged anuria in two siblings, and hypertension in all affected infants.
- All three cases resulted in a fatal outcome.
Findings:
- The familial clustering and similar age of onset suggest a strong genetic component in this specific HUS presentation.
- The clinical course was severe, marked by anuria and hypertension, leading to uniformly fatal outcomes.
Implications:
- A genetic predisposition for this severe form of familial HUS is highly probable.
- Genetic counseling should incorporate the possibility of inherited HUS when evaluating families with affected members.
- Further research into the specific genetic mechanisms underlying this familial HUS is warranted.
Abstract:
Three female infants in a single family developed a hemolytic uremic syndrome (HUS) at nearly identical ages, 11 1/2, 12, and 16 months respectively, years apart from each other. The course of the disease was characterized by slow onset, gradual deterioration and prolonged anuria in 2 siblings, hypertension and fatal outcome in all cases. A genetic predisposition for this type of familial HUS is probable and should be taken into account in genetic counseling.
