Abstract

Objective: To identify the relationship between serum immunoglobulin levels, complement components 3 and 4, the presence of the HLA-B27 allele and diagnosis of spondyloarthropathies in patients with non-infectious anterior uveitis.

Materials and methods: The participants were 197 patients with a non-infectious anterior uveitis. The concentrations of serum immunoglobulins, and C3 and C4 proteins of the complement were determined by turbidimetry. The personal history of suspected immunodeficiency, ophthalmological complications, arthralgia, family history of spondyloarthropathies and the presence of the HLA-B27 allele were collected.

Results: A family history of spondyloarthropathy, axial arthralgias, and ophthalmological complications were more frequent in HLA-B27 positive patients (P=.0005, P≤.0001, and P≤.0001, respectively) and in patients with spondyloarthropathy diagnoses (P≤.0001, P≤.0001, and P≤.0001, respectively). A personal history of recurrent sepsis, and gastrointestinal abnormalities was associated with the presence of the HLA-B27 allele (P≤.0001, and P=.0240, respectively) and with the diagnosis of spondyloarthropathy (P=.0492, and P=.0017, respectively). IgG decrease was observed (χ2=18.5, OR 5.03, 95% CI 2.32-10.89; P=.0001) and IgM (OR 7.13, 95% CI 1.40-36.4; P=.0128) in patients positive for the HLA-B27 allele and in patients with a diagnosis of spondyloarthropathies (P=.0364 and P=.0028, respectively). The decrease of C3 proteins (OR 4.82; CI 95% 1.35-17.11; P=.0328) and C4 (OR 9.09; CI 95% 2.13-38.88; P=.0074) were associated with a spondyloarthropathies diagnosis.

Conclusions: Patients with non-infectious anterior uveitis, positive for the HLA-B27 allele and diagnosed with spondyloarthropathies have alterations in serum immunoglobulin levels and complement components 3 and 4, which could contribute to the perpetuation and worse clinical course of this disease.
