Primary Sjögren's syndrome (SS) is a chronic autoimmune disease primarily involving the exocrine glands. SS clinical picture ranges from exocrinopathy to systemic disease affecting the lung, kidney, liver, skin, musculockeletal and the nervous system. The morbidity of SS is mainly determined by extraglandular disease and increased prevalence of lymphoma1. Environmental and hormonal factors, such as vitamin-D may play a role in the pathogenic process and disease expression2. Thus, we aimed to evaluate the association between vitamin-D concentrations and the manifestations of SS.
Vitamin-D levels were determined in 176 SS patients and 140 matched healthy volunteers utilizing the Liaison chemiluminescent immunoassays (DiaSorin-Italy), and correlated with clinical and serological manifestations of SS.
Vitamin-D levels were comparable between SS patients and control 20.5±10ng/ml and 21.6±10ng/ml respectively. Peripheral neuropathy or neuropathic pain were diagnosed in 23% of patients and associated with lower vitamin-D levels (18.6±5.5ng/ml vs. 22.6±8ng/ml (p=0.04)). Lymphoma was diagnosed in 4.3% of SS patients that showed vitamin-D deficiency 13.2±6.25ng/ml as compared with SS patients without lymphoma (22±8 ng/ml; p=0.03). Other clinical and serological manifestations did not correlate with vitamin-D status.
In this study, low levels of Vitamin-D correlated with the presence of peripheral nerve involvement and lymphoma among SS patients. The link between vitamin-D neuropathy and lymphoma was reported in other conditions, and may support a role for vitamin-D in the pathogenesis of these processes as well as a beneficial effect for vitamin-D supplementation.
