Cím:	The in vitro treatment with vitamin D3 is ineffective on the expression of PKC isoenzymes, but decreases further the impaired production of IL-2 in the T lymphocytes of SLE patients / Gabriella Czifra, Balázs Tóth, Ildikó Kovács, Tamás Bíró, Zoltán Griger, Sándor Baráth, Tünde Tarr, Margit Zeher, Sándor Sipka
Dátum:	2014
Megjegyzések:	The objective of the study was to investigate the possibility whether the in vitro treatment with vitamin D3 can restore the impaired expression of protein kinase C (PKC) isoenzymes and IL-2 production in the lymphocytes of patients with systemic lupus erythematosus (SLE). Purified T lymphocytes from 14 patients with SLE and 13 healthy controls were cultured for 48 h in the presence and absence of 1 and 100 nM doses of vitamin D3. The expressions of various PKC isoenzymes were tested by Western blot analysis, and the amounts of various cytokines were detected by ELISA in the culture supernatants. Neither the low (1 nM) nor the high (100 nM) doses of vitamin D3 (1α,-25-dihydroxyvitamin) applied in vitro for 48 h were able to restore the decreased expression of PKC isoenzymes in the T cells of SLE patients. However, 100 nM of vitamin D3 significantly increased the release of IL-10, but suppressed the production of IL-2, IL-6, interferon γ and TNF α in the culture supernatants of both groups. As the low production of IL-2 is one of the main pathologic features of SLE, we recommend to avoid the use of high doses of vitamin D3 for treatment of lupus patients with vitamin D3 deficiency.

Cím:	Vitamin D receptor gene polymorphism in rheumatoid arthritis and associated osteoporosis / Rass, P., Pakozdi, A., Lakatos, P., Zilahi, E., Sipka, S., Szegedi, G., Szekanecz, Z.
Dátum:	2006

Megjegyzések:	Rheumatoid arthritis (RA) is commonly associated with decreased bone mineral density (BMD) due to numerous factors. BsmI polymorphism of the vitamin D receptor (VDR) gene has been implicated in the pathogenesis of osteoporosis. Vitamin D has several immunomodulatory effects and thus may play a role in the course of arthritis. However, little data is available on the possible relationship between RA and VDR gene polymorphisms. In this study, the frequency of BsmI polymorphism genotypes were compared with that found in other countries. In this study, 64 RA patients and 40 healthy controls were tested for VDR gene BsmI polymorphism genotypes. Frequencies of B and b alleles were associated with markers of bone metabolism and RA. Among control subjects, the frequency of the BB genotype is relatively high (27.5%). In RA with secondary osteopenia/osteoporosis the BB genotype was more rare, the bb was more common than in control subjects. Markers of bone metabolism were associated with the B allele. RA patients carrying the B allele had lower BMD and increased bone loss over 1 year. The B allele was also correlated with increased osteoclast and osteoblast function, as determined by the assessment of biochemical markers of bone metabolism. Rheumatoid factor titer, which is an independent marker for disease progression in RA, was higher in bb patients. Our data suggest, that the imbalance in B and b allele expression may be involved in the pathogenesis of RA-associated osteoporosis. The possible involvement of vitamin D and VDR gene polymorphisms in the development and progression of RA needs further elucidation.
