Hyperthyroidism, diabetes mellitus and the congenital rubella syndrome
Insights
Congenital rubella syndrome can lead to multiple endocrine disorders, including diabetes mellitus and thyroid issues. Certain human leukocyte antigen (HLA) types may increase susceptibility to rubella infection.
Area of Science:
- Pediatrics
- Immunology
- Endocrinology
Background:
- Congenital rubella syndrome (CRS) is a preventable condition caused by maternal rubella infection during pregnancy.
- CRS can result in a wide range of developmental abnormalities and long-term health complications.
Observation:
- A male patient presented with classic CRS symptoms: mental retardation, neuro-sensory deafness, dental enamel hypoplasia, and chorioretinitis.
- The patient later developed hyperthyroidism, premature craniosynostosis, and overt diabetes mellitus.
Findings:
- The patient's endocrine disorders, hyperthyroidism and diabetes mellitus, were successfully managed with medication.
- Human leukocyte antigen (HLA) typing revealed antigens A2, B8, and B40.
- The co-occurrence of multiple endocrine disorders in this CRS patient is notable.
Implications:
- This case highlights the potential for diverse and late-onset endocrine complications following congenital rubella infection.
- The presence of HLA B8 antigen may be associated with an increased susceptibility to rubella infection and subsequent complications.
- Further research into the interplay between genetic factors like HLA and viral infections is warranted to understand disease pathogenesis and susceptibility.
Abstract:
A male patient born to a mother who developed rubella during the tenth week of gestation presented a typical congenital rubella syndrome with mental retardation, neuro-sensory deafness, hypoplasia of the dental enamel and chorioretinitis. Hyperthyroidism occurred at the age of 3 10/12 years and was treated successfully with propylthiouracil for 4 years. The course was complicated by premature craniosynostosis and a craniectomy was performed at the age of 7 years. Overt diabetes mellitus developed at 17 years and was well controlled by insulin therapy. Histocompatilibity (HLA) antigens were A2, B8, B40. Diabetes mellitus and thyroid disorders have previously been reported after congenital rubella, and recently after congenital cytomegalovirus infection. Our patient had both endocrinopaties. It is possible that HLA B8 antigens might be responsible for increased susceptibility to rubella infection.
