Sarcoidosis in young children
Insights
Pediatric sarcoidosis in young children presents uniquely, often lacking lung issues but featuring uveitis, arthritis, and skin rash. Early treatment with adrenocorticosteroids can manage chronic arthritis and eye involvement.
Area of Science:
- Pediatric Rheumatology
- Dermatology
- Ophthalmology
Background:
- Sarcoidosis is a multisystem inflammatory disease of unknown cause.
- While typically affecting adults, sarcoidosis can occur in children, with distinct clinical presentations in younger age groups.
Observation:
- A review of 28 reported cases of sarcoidosis in children 4 years or younger reveals unique characteristics.
- Infants and toddlers with sarcoidosis often present without pulmonary involvement.
- Predominant symptoms include uveitis, arthritis, and skin rash, differentiating them from older pediatric patients.
Findings:
- The disease course in this age group can include chronic arthritis and potential renal complications due to hypercalciuria.
- Early-onset sarcoidosis in very young children exhibits a distinct clinical phenotype compared to older children.
Implications:
- Adrenocorticosteroids show potential efficacy in managing ocular and renal manifestations of pediatric sarcoidosis.
- Recognizing this distinct presentation is crucial for timely diagnosis and appropriate management in infants and toddlers.
Abstract:
Twenty-eight cases of sarcoidosis in children 4 years of age or younger have been reported in the literature, including the case presented herein. These patients may display a distinct aspect of this disease. Half of them are younger than 1 year and all but two are whit. Clinically, they are different from the older children: they lack pulmonary disease, and they predominantly have uveitis, arthritis, and skin rash. The natural history of the disease not only involves chronic arthritis, but has the potential for renal disease secondary to hypercalciuria. Use of adrenocorticosteroids may be effective in these situations, as well as for eye involvement.
