Inadequate vitamin D status is associated with secondary hyperparathyroidism and increased bone turnover and bone loss, which in turn increases fracture risk. The objective of this study is to assess the prevalence of inadequate vitamin D status in European women aged over 80 years. Assessments of serum 25-hydroxyvitamin D levels (25(OH)D) were performed on 8532 European women with osteoporosis or osteopenia of which 1984 were aged over 80 years. European countries included in the study were: France, Belgium, Denmark, Italy, Poland, Hungary, United Kingdom, Spain and Germany. Two cut-offs of 25(OH)D inadequacy were fixed: <75 nmol/L (30 ng/ml) and <50 nmol/L (20 ng/ml). Mean (SD) age of the patients was 83.4 (2.9) years, body mass index was 25.0 (4.0) kg/m2 and level of 25(OH)D was 53.3 (26.7) nmol/L (21.4 [10.7] ng/ml). There was a highly significant difference of 25(OH)D level across European countries (p < 0.0001). In these women aged over 80 years, the prevalence of 25(OH)D inadequacy was 80.9% and 44.5% when considering cut-offs of 75 and 50 nmol/L, respectively. In the 397 (20.0%) patients taking supplemental vitamin D with or without supplemental calcium, the mean serum 25(OH)D level was significantly higher than in the other patients (65.2 (29.2) nmol/L vs. 50.3 (25.2) nmol/L; P < 0.001). This study indicates a high prevalence of vitamin D (25(OH)D) inadequacy in old European women. The prevalence could be even higher in some particular countries. [less ▲]

Besides its well-known effect on bone metabolism, recent researches suggest that vitamin D may also play a role in the muscular, immune, endocrine, and central nervous systems. Double-blind RCTs support vitamin D supplementation at a dose of 800 IU per day for the prevention of falls and fractures in the senior population. Ecological, case–control and cohort studies have suggested that high vitamin D levels were associated with a reduced risk of autoimmune diseases, type 2 diabetes, cardio-vascular diseases and cancer but large clinical trials are lacking today to provide solid evidence of a vitamin D benefit beyond bone health. At last, the optimal dose, route of administration, dosing interval and duration of vitamin D supplementation at a specific target dose beyond the prevention of vitamin D deficiency need to be further investigated.

Determining the level of glycated haemoglobin, in particular its major fraction called HbA1c, is an attractive tool in the management of diabetic patients. In fact, it provides a global evaluation of the glycemic control’s level through the past 8-12 weeks. However, this tool must be used with caution. First of all, it does not allow to examine the glycemic kinetics since it represents a glycemic average. Secondly, it does not allow to appreciate the glycemic evolution through the full day. This dosage needs then sometimes to be complemented by fingersticks blood glucose testing. Last but not least, caution is advised in interpreting the results because a number of physiological, pathological and technical factors might interfere with HbA1c measurement. It is therefore important that physicians keep a critical view of the values obtained. The paper reviews the different methods used to determine the level of glycated haemoglobin and their limitations. It also emphasizes the medical situations in which over- and under-estimation of the real HbA1c value could occur. It does not address the specific issue of the new expression values of HbA1c in mmol/mol instead of %. Moreover, the medical situations in which over- and under estimation of the real HbA1c value could occur will be described. [less ▲]
