Megjegyzések:Low vitamin D serum concentrations have been reported in several autoimmune conditions. The study's aim was to explore such a relationship in a large multinational population of patients with systemic sclerosis (SSc) and to pursue possible clinical and laboratory correlates with vitamin D concentrations. 327 sera samples of European patients with SSc and 141 samples of compatible healthy controls were studied for vitamin D concentrations using the commercial kit LIAISON 25-OH vitamin D assay (Diasorin). Additionally, clinical parameters including the Rodnan skin score, diffusing lung capacity for carbon monoxide (DLCO), systolic pulmonary artery pressure (sPAP), forced vital capacity (FVC), and nailfold video capillaroscopic, erythrocyte sedimentation rate (ESR), anti-nuclear antibodies (ANA and scl70), rheumatoid factor (RF) were investigated. Vitamin D serum concentration was 13.5+/-9.0ng/ml (mean+/-standard deviation) in patients with SSc compared to 21.6+/-9.7ng/ml in a control group (p<0.001). A negative correlation between patients' age and vitamin D concentration (r=-0.2, p<0.05, n=96) was observed. An inverse relationship was found between skin involvement and vitamin D serum concentrations; Patients with a Rodnan skin score of 10 or lower (n=11) had a mean vitamin D concentration of 17.7+/-10.4ng/ml compared to patients with a score above 10 (n=28) 8+/-10.1ng/ml (p=0.02, by the Mann-Whitney test). In conclusion, Patients with SSc have significantly lower serum vitamin D concentrations compared to healthy controls; moreover fibrosis of the cutaneous tissue is inversely related to the vitamin D concentration.

Megjegyzések:Multiple sclerosis (MS) is a common demyelnating disorder of the central nervous system (CNS) and ethiopathogenesis has yet to be fully elucidated. The disease may present in several clinical forms that are closely associated with disease morbidity. In recent years various environmental and hormonal factors have been implicated in the pathogenesis of autoimmunity. OBJECTIVES: To evaluate ferritin and prolactin levels in MS patients and their correlation with clinical manifestations of the disease. METHODS: Serum samples from 150 multiple sclerosis patients were evaluated for demographic characteristics, clinical parameters as well as prolactin and ferritin levels utilizing the Liaison chemiluminescent immunoassays (DiaSorin, Italy). Sera from 100 matched healthy donors were used as controls. RESULTS: Hyperprolactinemia was documented in 10 of 150 MS patients (6.7%) and hyperferritinemia in 12 (8%), both of which were significantly more common in this group compared with healthy controls (P < 0.01 and P = 0.02 respectively). Among female MS patients, elevated prolactin levels were related to the secondary-progressive type of disease (P = 0.05), whereas hyperferritinemia was associated with male gender (P = 0.03) and with the relapsing-progressive type of the disease (P = 0.02). An inverse association was found between hyperferritinemia and the relapsing-remitting type of MS in male patients (P = 0.05) CONCLUSIONS: Our results suggest a plausible association between these biomarkers and certain clinical types and gender among MS patients. Further studies combining clinical data, CNS imaging and these markers are warranted.

Cím:Vitamin D and autoimmune thyroid diseases / Kivity, S., Agmon-Levin, N., Zisappl, M., Shapira, Y., Nagy, E. V., Danko, K., Szekanecz, Z., Langevitz, P., Shoenfeld, Y.

Megjegyzések:The role of vitamin D as an immune modulator has been emphasized in recent years, and low levels of the hormone were observed in several autoimmune diseases including multiple sclerosis and systemic lupus erythematosus. Vitamin D mediates its effect though binding to vitamin D receptor (VDR), and activation of VDR-responsive genes. While VDR gene polymorphism was found to associate with autoimmune thyroid diseases (AITDs), few studies examined levels of vitamin D in these patients and those that did yielded conflicting results. We therefore undertook to evaluate the levels of vitamin D in patients with AITDs compared to patients with non-AITDs and healthy controls. Serum vitamin D (25-OH) levels were measured in 50 patients with AITDs, 42 patients with non-AITDs and 98 healthy subjects, utilizing the LIAISON chemiluminescence immunoassay (DiaSorin, Saluggia, Italy). Vitamin D deficiency was designated at levels lower than 10 ng/ml. Antithyroid antibodies, thyroid functions and demographic parameters were evaluated in all patients. The prevalence of vitamin D deficiency was significantly higher in patients with AITDs compared with healthy individuals (72% versus 30.6%; P<0.001), as well as in patients with Hashimoto's thyroiditis compared to patients with non-AITDs (79% versus 52%; P<0.05). Vitamin D deficiency also correlated to the presence of antithyroid antibodies (P=0.01) and abnormal thyroid function tests (P=0.059). Significantly low levels of vitamin D were documented in patients with AITDs that were related to the presence of anti thyroid antibodies and abnormal thyroid function tests, suggesting the involvement of vitamin D in the pathogenesis of AITDs and the advisability of supplementation.Cellular & Molecular Immunology advance online publication, 31 January 2011; doi:10.1038/cmi.2010.73.

Megjegyzések:Evidence points to an association of prolactin to autoimmune diseases. We examined the correlation between hyperprolactinemia and disease manifestations and activity in a large patient cohort. Age- and sex-adjusted prolactin concentration was assessed in 256 serum samples from lupus patients utilizing the LIASON prolactin automated immunoassay method (DiaSorin S.p.A, Saluggia, Italy). Disease activity was defined as present if European Consensus Lupus Activity Measurement (ECLAM) > 2 or Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) > 4. Lupus manifestations were grouped by organ involvement, laboratory data, and prescribed medications. Hyperprolactinemia was presented in 46/256 (18%) of the cohort. Hyperprolactinemic patients had significantly more serositis (40% vs. 32.4%, p = 0.03) specifically, pleuritis (33% vs. 17%, p = 0.02), pericarditis (30% vs. 12%, p = 0.002), and peritonitis (15% vs. 0.8%, p = 0.003). Hyperprolactinemic subjects exhibited significantly more anemia (42% vs. 26%, p = 0.02) and marginally more proteinuria (65.5% vs. 46%, p = 0.06). Elevated levels of prolactin were not significantly associated with other clinical manifestations, serology, or therapy. Disease activity scores were not associated with hyperprolactinemia. Hyperprolactinemia in lupus patients is associated with all types of serositis and anemia but not with other clinical, serological therapeutic measures or with disease activity. These results suggest that dopamine agonists may be an optional therapy for lupus patients with hyperprolactinemia.

Megjegyzések:Ferritin may play a direct role on the immune system. We sought to determine if elevated levels of ferritin in lupus patients correlate with disease activity and organ involvement in a large cohort. Ferritin levels (gender and age adjusted) were assessed in 274 lupus serum samples utilizing the LIASON Ferritin automated immunoassay method. Significant disease activity was determined if European Consensus Lupus Activity Index (ECLAM) > 2 or Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) > 4. Utilizing an EXCEL database, we compared elevated ferritin levels to manifestations grouped by organ involvement, serology, and previous therapy. The patients were predominantly female (89%), median age was 37 years old, and disease duration was 10.6 +/- 7.7 years. Hyperferritinemia was found in 18.6% of SLE patients. Compared to subjects with normal ferritin levels, a significantly greater proportion of patients with hyperferritinemia had thrombocytopenia (15.4% vs. 33.3%, p = 0.003) and lupus anticoagulant (11.3% vs. 29.0%, p = 0.01). Additionally, compared to normoferritinemic subjects, hyperferritinemic subjects had significantly higher total aCL (99.7 +/- 369 vs. 30.9 +/- 17.3 GPI, p = 0.02) and aCL IgM antibody levels (75.3 +/- 357.4 vs. 9.3 +/- 10.3 GPI, p = 0.02), and marginally lower aCL IgG antibody levels (9.2 +/- 4.9 vs. 9.7 +/- 3.9 GPI, p = 0.096). While the ECLAM score significantly correlated with hyperferritinemia (p = 0.04), the SLEDAI score was marginally associated with hyperferritinemia (p = 0.1). Serositis was marginally associated with hyperferritinemia, but not with other manifestations. An association with serologic APS was encountered. Hyperferritinemia was associated with thrombocytopenia, lupus anticoagulant, and anti-cardiolipin antibodies suggest that it may be an early marker for secondary antiphospholipid syndrome in SLE patients.
