To investigate the correlation between depressive symptoms and serum vitamin D levels in stroke patients.
In total, 126 stroke patients were analyzed. The 25-hydroxyvitamin D (25-OHD) concentration of each patient was used to determine their vitamin D status. Depressive symptoms were assessed using the Beck Depression Inventory II (BDI-II) and the Patient Health Questionnaire 9 (PHQ-9). Functional status was evaluated with the Korean version of the Modified Barthel Index (K-MBI). We compared the clinical questionnaires of a vitamin D-deficient group and a normal group, and evaluated the correlations between BDI-II, PHQ-9, K-MBI, and serum 25-OHD levels.
In the vitamin D-deficient group, BDI-II (16.0±12.1) and PHQ-9 (7.4±4.2) scores were significantly higher than those of the normal group (BDI-II, 9.1±7.2; PHQ-9, 4.2±2.9; p<0.01). In a Spearman correlation analysis, a significant negative correlation was found between serum 25-OHD levels and BDI-II (Spearman r=0.177, p=0.048), but there were no significant correlations between serum 25-OHD levels and PHQ-9 or K-MBI.
Vitamin D deficiency was correlated with the symptoms of depression in stroke patients.

Objective: To assess change of bone metabolism in hemiplegic patients after stroke.
Method: Sera were collected from 19 hemiplegic patients after stroke. Sera were assayed for 25-hydroxyvitamin D (25-OHD), 1,25-dihydroxyvitamin D (1,25-(OH)2D), parathyroid hormone (PTH), calcium and osteocalcin.
Results: Serum 25-OHD and 1,25-(OH)2D concentration were 15.13 mg/mL and 20.88 pg/mL, respectively. Serum PTH was 47.23 pg/mL. In 5 (26%) of the patients, the serum 25-OHD concentration were <10 ng/mL (deficient level). Ten (52%) of the patients had vitamin D concentrations between 10 and 20 ng/mL (insufficient level). The mean PTH concentration was not significantly higher in patients with deficient levels of 25-OHD (61.80 pg/mL) than those with insufficient (43.63 pg/mL) or sufficient (38.05 pg/mL) levels of 25-OHD. Serum 25-OHD concentration were lower in the late group (11.11 mg/mL) than in the early group (18.05 mg/mL), whereas serum PTH concentration were higher in the late group (58.96 pg/mL) than in the early group (38.70 pg/mL).
Conclusion: Compensatory hyperparathyroidism with hypovitaminosis D occurred in the hemiplgic patients after stroke, especially more than one year from onset.
