Serum 25-Hydroxyvitamin D3 and BAFF Levels Are Associated with Disease Activity in Primary Sjogren’s Syndrome

Table 2

Correlations between serum levels of 25(OH)-D3, BAFF, or β₂ microglobulin and serological parameters were evaluated in primary Sjogren’s syndrome.

	25(OH)-D3		BAFF		β2 microglobulin
	Correlation efficient	value	Correlation efficient	value	Correlation efficient	value
Age	−0.110	0.366	0.101	0.493	0.233	0.086
ESR	0.174	0.153	0.311		0.498	<
CRP	−0.009	0.941	0.281	0.055	0.296
25(OH)-D3			−0.028	0.849	−0.096	0.485
BAFF	−0.028	0.849			0.215	0.147
β2 microglobulin	−0.096	0.485	0.215	0.147

Correlation coefficient and value were analyzed by Spearman’s rank correlation test. ESR = erythrocyte sedimentation rate; CRP = C-reactive protein; BAFF = B cell activation of the TNF family; .
