ABSTRACT: To investigate the relationship between serum immunoglobulin levels and corneal opacities in a cohort of patients with human T-cell lymphotrophic virus type-1 (HTLV-1).
Retrospective case series.
Complete ophthalmologic examination was performed on 44 patients with HTLV-1 infection (25 patients with adult T-cell leukemia/lymphoma [ATL], 18 patients with HTLV-1 that was associated myelopathy/tropical spastic paraparesis [HAM/TSP], and one patient who was asymptomatic). Corneal opacities were described by shape, size, color, and location. Serum immunoglobulin (Ig) levels (IgG, IgM, and IgA) were measured by nephelometry.
Corneal opacities were identified in 15 of 25 patients (60%) with ATL and five of 18 patients (28%) with HAM/TSP. The prevalence of corneal opacities was associated statistically with elevated IgG level (P = .023) in patients with ATL, but not in patients with HAM/TSP (P > .99).
Although the mechanism remains unclear, hypergammaglobulinemia is associated with the development of the corneal opacities in patients of African descent with ATL.
