Abstract Loop diuretics (LD) may affect bone health by inhibiting renal calcium reuptake. However, whether vitamin D status and dietary calcium intake modify the association between LD and bone outcome is unclear. Therefore, this study aimed to evaluate whether vitamin D level or calcium intake modify the association between LD and various indices of bone health including bone mineral density (BMD) and Trabecular Bone Score (TBS). From The Rotterdam Study, a prospective population-based cohort study, we used data from 6990 participants aged > 45 year with a DXA scan (2002–2008), 6908 participants with femoral neck (FN)-BMD, 6677 participants with lumbar spine (LS)-BMD and 6476 participants with LS-TBS measurements. Use of LD was available from pharmacy dispensing records. Vitamin D (25(OH)D) level was measured in serum, and dietary calcium intake was measured with a validated food frequency questionnaire. Almost eight percent of the participants used LD. The association between LD (past-users compared to never-users) and LS-TBS was significantly different by 25(OH)D concentrations (P for interaction = 0.04). A significantly lower LS-TBS among LD past-users was observed for 25(OH)D ≥ 50 nmol/l compared to ≤ 20 and 20–50 nmol/l (β = − 0.036, 95% CI − 0.060; − 0.013 vs. β = − 0.012, 95% CI − 0.036; 0.013 and β = − 0.031, 95% CI − 0.096; 0.034, respectively). However, no other significant effect modification by 25(OH)D and dietary calcium intake was found in the associations between LD use and bone health outcomes (P-interaction > 0.13). This study suggests that the association between LD use and indices of bone health is not consistently modified by vitamin D or dietary calcium intake.

25 Hydroxycholecalciferol

1. Chromatography measurements indicated that adult rats converted 25-hydroxycholecalciferol into 1,25-dihydroxycholecalciferol at a lower rate than that reported earlier for young animals. In serum, less-polar metabolites were found which probably represented vitamin D esters and vitamin D3. 2. A low dietary intake of calcium resulted in an evident increase in the fraction corresponding to 1,25-dihydroxycholecalciferol in the kidneys and also in the intestinal mucosa and serum. 3. Inclusion of 0·67 mmol of cadmium/l of drinking water at a low dietary intake of calcium resulted in an increased accumulation of both cadmium and zinc in the kidneys and liver compared with values at a normal dietary calcium intake. 4. At a normal dietary calcium intake, cadmium exposure caused inhibited production of 1,25-dihydroxycholecalciferol by the kidneys and an increased accumulation of 24,25-dihydroxycholecalciferol, vitamin D3 and vitamin D esters in the serum. 5. The inhibitory effect of cadmium on the renal conversion of 25-hydroxycholecalciferol into 1,25-dihydroxycholecalciferol was almost completely counteracted by a simultaneous low dietary calcium intake. Cadmium-exposed, calcium-deficient animals also showed a maintained accumulation of 1,25-dihydroxycholecalciferol in the intestinal mucosa.

Vitamin D Supplements

Abstract Introduction 1 in 2 women and 1 in 5 men will suffer a fragility fracture. Research into calcium and vitamin D supplements has found no consistent evidence to suggest that they reduce the risk of osteoporotic fractures. There has been little research to suggest that dietary calcium is effective at reducing the risk osteoporotic fractures, but supplements have been linked to increased risk of cardiovascular disease and urinary stones. Bisphosphonates have been shown to reduce the risk of osteoporotic fractures and are usually taken in combination with calcium and vitamin D supplements given that deficiencies must be corrected prior to starting. This study set out to assess the dietary calcium intake of patients who attend the falls clinic and explore their attitudes towards dietary change, as an alternative or adjunct to a calcium and vitamin D tablet. Methods Data was collected during private interviews conducted with patients who attended the falls clinic. The Edinburgh University Centre for Genomic and Experimental research (CGEM) food frequency calculator was used to calculate dietary calcium intake. Microsoft Excel was used to collate and analyse the data. Results No association was found between dietary calcium intake, age and sex. We did find that mean dietary calcium intake was significantly less than the recommended daily amount for adults with osteoporosis, with 80% not getting their recommended daily intake (p < 0.05). We identified patients who don’t receive a calcium and vitamin D supplement as an at-risk group who would benefit from advice on sources of dietary calcium and 83% of patients said that they would be interested in a leaflet on sources of dietary calcium. Conclusion This study has identified a group of patients who will hopefully benefit from a leaflet on sources of dietary calcium and as result improve their bone health.
