The EPATH trial
Observational studies suggested a link between bone disease and left
ventricular (LV) dysfunction that may be pronounced in hyperparathyroid
conditions. We therefore aimed to test the hypothesis that circulating markers
of bone turnover correlate with LV function in a cohort of patients with
primary hyperparathyroidism (pHPT). Cross-sectional data of 155 subjects with
pHPT were analyzed who participated in the “Eplerenone in Primary
Hyperparathyroidism” (EPATH) Trial. Multivariate linear regression analyses
with LV ejection fraction (LVEF, systolic function) or peak early transmitral
filling velocity (e’, diastolic function) as dependent variables and
N-terminal propeptide of procollagen type 1 (P1NP), osteocalcin (OC), bone-
specific alkaline phosphatase (BALP), or beta-crosslaps (CTX) as the
respective independent variable were performed. Analyses were additionally
adjusted for plasma parathyroid hormone, plasma calcium, age, sex, HbA1c, body
mass index, mean 24-hours systolic blood pressure, smoking status, estimated
glomerular filtration rate, antihypertensive treatment, osteoporosis
treatment, 25-hydroxy vitamin D and N-terminal pro-brain B-type natriuretic
peptide. Independent relationships were observed between P1NP and LVEF
(adjusted β-coefficient = 0.201, P = 0.035) and e’ (β = 0.188, P = 0.042),
respectively. OC (β = 0.192, P = 0.039) and BALP (β = 0.198, P = 0.030) were
each independently related with e’. CTX showed no correlations with LVEF or
e’. In conclusion, high bone formation markers were independently and
paradoxically related with better LV diastolic and, partly, better systolic
function, in the setting of pHPT. Potentially cardio-protective properties of
stimulated bone formation in the context of hyperparathyroidism should be
explored in future studies

Rationale and plan for vitamin D food fortification: a review and guidance paper
Vitamin D deficiency can lead to musculoskeletal diseases such as rickets and osteomalacia, but vitamin D supplementation may also prevent extraskeletal diseases such as respiratory tract infections, asthma exacerbations, pregnancy complications and premature deaths. Vitamin D has a unique metabolism as it is mainly obtained through synthesis in the skin under the influence of sunlight (i.e., ultraviolet-B radiation) whereas intake by nutrition traditionally plays a relatively minor role. Dietary guidelines for vitamin D are based on a consensus that serum 25-hydroxyvitamin D (25[OH]D) concentrations are used to assess vitamin D status, with the recommended target concentrations ranging from >= 25 to >= 50 nmol/L (>= 10->= 20 ng/mL), corresponding to a daily vitamin D intake of 10 to 20 mu g (400-800 international units). Most populations fail to meet these recommended dietary vitamin D requirements. In Europe, 25(OH)D concentrations < 30 nmol/L (12 ng/mL) and < 50 nmol/L (20 ng/mL) are present in 13.0 and 40.4% of the general population, respectively. This substantial gap between officially recommended dietary reference intakes for vitamin D and the high prevalence of vitamin D deficiency in the general population requires action from health authorities. Promotion of a healthier lifestyle with more outdoor activities and optimal nutrition are definitely warranted but will not erase vitamin D deficiency and must, in the case of sunlight exposure, be well balanced with regard to potential adverse effects such as skin cancer. Intake of vitamin D supplements is limited by relatively poor adherence (in particular in individuals with low-socioeconomic status) and potential for overdosing. Systematic vitamin D food fortification is, however, an effective approach to improve vitamin D status in the general population, and this has already been introduced by countries such as the US, Canada, India, and Finland. Recent advances in our knowledge on the safety of vitamin D treatment, the dose-response relationship of vitamin D intake and 25(OH)D levels, as well as data on the effectiveness of vitamin D fortification in countries such as Finland provide a solid basis to introduce and modify vitamin D food fortification in order to improve public health with this likewise cost-effective approach
