The presence of vitamin D receptors in the cells of the immune system and the fact that several of these cells produce the vitamin D hormone suggested that vitamin D could have immunoregulatory properties and now potent immuno-mudulatory activities on dendritic cells Th1 and Th17 cells as well as B cells have been confirmed. Patients with undifferentiated connective tissue disease also show vitamin D deficiency and interestingly patients who progress into connective tissue diseases have lower vitamin D levels than those who remain in the undifferentiated connective tissue disease stage. Vitamin D deficiency and autoimmune diseases The recent study by Zold and colleagues 1 reports that a seasonal variance in levels of 25 OH D3 was identified in patients with undifferentiated connective tissue disease UCTD and showed that these levels were in any case significantly lower than in controls during the corresponding seasons. The results showed also that more severe vitamin D deficiency in UCTD patients may play a role in the subsequent progress into well-defined connective tissue diseases CTDs . Epidemiological evidence indicates a significant .
