Purpose: To report on a rare case of intermediate uveitis occurring in a patient with common variable immunodeficiency (CVID) and a heterozygous TNFRSF13B variant.
Methods: Observational case report.
Results: A 23-year-old male presented with a 3-month history of increasing floaters and blurred vision to both eyes. He had been treated with topical and intravitreal corticosteroids by his local ophthalmologist nine months before. Ocular examination demonstrated bilateral intermediate uveitis with retinal vasculitis. He had been treated with intravenous immunoglobulins during childhood, due to primary humoral immunodeficiency. Systemic work-up for other causes of intermediate uveitis was unremarkable, notably no features of systemic sarcoid-like disease were detected. Initial treatment with mycophenolate mofetil showed insufficient response, and upon switching to adalimumab, clinical remission was achieved. Immunocytometry and genetic work-up revealed a smB+CD21norm subtype of CVID and a heterozygous TNFRSF13B variant.
Conclusion: This report of CVID-associated intermediate uveitis in a patient with a heterozygous TNFRSF13B variant highlights the potential involvement of the eye within CVID-associated autoimmunity and the role for anti-TNF blockade in this challenging group of patients.
