Summary: | Polyclonal elevation of immunoglobulins is classically described in sarcoidosis and could possibly be useful in the work-up of suspected sarcoidosis uveitis. Because exposure to viruses of the herpes group is high in all populations, determination of herpes serologies is probably suited for this purpose.
Therefore serum anti-herpes antibody patterns in sarcoidosis (SARC), HLA-B27 positive acute anterior uveitis (AAU), pars planitis (PP) and healthy age-matched controls were analysed. Frozen sera were analysed for exposure to CMV, HSV, VZV by ELISA IgG testing and to EBV-VCA by immunofluorescence. Complement fixing titers > or = 1/40 and an EBV-VCA titer > or = 1/1280 were considered elevated. For each patient exposed to 2 or more herpes viruses, a score made out of the number of elevated titers divided by the number of herpes viruses the patient was exposed to, was calculated and mean scores were compared using Student's t-test.
Mean score of patients with sarcoidosis was 0.47 +/- 0.27 (N = 18, mean age 60.2 +/- 21.4 years), significantly higher than AAU (N = 21; score 0.12 +/- 0.2; p < or = 0.000), than PP (N = 20; score 0.18 +/- 0.2; p < 0.003), and than age-matched healthy controls (N = 341, mean age 59 +/- 5.5 years; score = 0.15 +/- 0.14; p < 0.000).
Anti-herpes antibodies were found to be significantly elevated in sarcoidosis uveitis, suggesting that herpes serologies may be useful in the work-up of suspected ocular sarcoidosis, a disease for which sufficiently sensitive and specific tests are lacking. |
