Aim. To investigate the vitamin D status in highly productive cows during winter housing period and effect of cholecalciferol by various ways of vitamin D 3 injection to cows in last days of gestation and after calving. Methods. Enzyme-linked immunoassay, spectrophotometry. Results. It has been stated that intramuscular injection of cholecalciferol into cows caused increase of the vitamin D 3 active metabolite – 25-OHD 3 , calcium, phosphorus and magnesium levels together with decrease of alkaline phosphatase level in pre- and post-natal periods. Oral supplementation makes little infl uence on the studied blood parameters of cows. Conclusions. Extrabuccal administration and oral supplementation of cholecalciferol in winter housing period to high-yield cows in the last days of gestation and after calving is accompanied by increased levels of its metabolites and their effect on mineral metabolism in the postnatal period. The nature of these changes depends on the mode of vitamin D administration and the physiological state of the cows.

Vitamin K (VK) and vitamin D (VD) deficiency/insufficiency is a common feature of chronic kidney disease (CKD), leading to impaired bone quality and a higher risk of fractures. CKD patients, with disturbances in VK and VD metabolism, do not have sufficient levels of these vitamins for maintaining normal bone formation and mineralization. So far, there has been no consensus on what serum VK and VD levels can be considered sufficient in this particular population. Moreover, there are no clear guidelines how supplementation of these vitamins should be carried out in the course of CKD. Based on the existing results of preclinical studies and clinical evidence, this review intends to discuss the effect of VK and VD on bone remodeling in CKD. Although the mechanisms of action and the effects of these vitamins on bone are distinct, we try to find evidence for synergy between them in relation to bone metabolism, to answer the question of whether combined supplementation of VK and VD will be more beneficial for bone health in the CKD population than administering each of these vitamins separately.

ZusammenfassungEine tägliche Vitamin-D-Supplementierung für Säuglinge bis zum zweiten erlebten Frühsommer zur Prävention der Rachitis und die Gabe von Vitamin K1 bei Neugeborenen zur Prävention von Vitamin-K-Mangel-Blutungen sind empfohlen.Seit einiger Zeit sind in Österreich Kombinationsprodukte der beiden fettlöslichen Vitamine D3 und K2 auf dem Markt erhältlich, die mit gesundheitsfördernden Effekten wie verbesserter Knochenmineralisation und Schutz vor vaskulärer Kalkeinlagerung beworben werden.Die Wirkung einer kombinierten Supplementierung von Vitamin D und Vitamin K2 bei Kindern ist aus physiologischer Sicht gesehen zwar potenziell sinnvoll, um Effekt, Risiken oder unerwünschte Nebenwirkungen zu evaluieren. Zuvor werden aber Dosisfindungs- und Sicherheitsstudien für die kombinierte Verabreichung benötigt. Insbesondere sind randomisierte kontrollierte Studien bei Risikokindern und Frühgeborenen notwendig. Solange diese Daten nicht vorliegen, erscheint die Gabe von Vitamin D in Kombination mit Vitamin K2 im Kindesalter nicht gerechtfertigt und kann daher auch nicht empfohlen werden.

Background: Osteoporosis is a common age related problem especially in women, with a consequent increase in bone fragility and susceptibility to fracture. Apart from Calcium, another nutrient that plays an important role in the mineralization of skeleton in Vitamin D. Osteocalcin, which is produced primarily by osteoblasts during bone formation, is considered to be one of the markers for osteoporosis.Methods: 314 women above the age of 40 were included into the study. A thorough physical and clinical examination, assessment of vital parameters, anthropometry evaluation was done for all patients. Bone mineral density was calculated using central DXA osteodensitometer at lumbar spine L1-L4, hip and ultradistal radius (in some cases.). Blood samples were taken for the detection of ionized calcium, phosphorus, alkaline phosphatase, 25hydroxivitamin D (25 ODH) and serum parathyroid hormone (PTH) by chemiluminiscent assay. Bone markers such as osteocalcin were measured as required.Results: Out of the 314 women attending our OPD, 96 of them were diagnosed as having osteoporosis. 24 out of them had fragility fractures, mainly of the hip, and 82 had ostepenia. Elevated levels of calcium (8.96 mg/dl), parathyroid hormone (58.76 pg/ml) and osteocalcin (24.46 ng/ml) were observed. Vitamin D deficiency of ≤ 20 was seen in 59 (63%) of the cases, insufficient in 23 (24%) and only 12 (13%) of these women had normal Vitamin D levels.Conclusions: Osteocalcin is a promising marker for the detection of osteoporosis. There is a considerable Vitamin D deficiency among the women with osteoporosis, and it is under-treated. It is essential to provide Vitamin D supplementation to these women especially those who are at high risk for fragility fractures.
