“…In the presented study, an attempt has been made to assess the impact of functional capacity on the levels of vitamin D3, B12 and folic acid. Subjects with a functional deficit were characterised by a reduced mean value of folic acid and vitamin D3 in the blood serum, compared to the group of patients with good mobility.This correlation has been confirmed by the studies of Van Pottelbergh et al [30], who examined 325 people aged 80 and above residing in Belgium, proving that the higher level of vitamin D3 was correlated with the activity and physical fitness of the subjects. Similar conclusions were formulated by Rafiq et al [31], studying the effect of vitamin D3 supplementation on the physical fitness of patients with COPD.…”

Introduction and objective. Deficits of vitamin resources constitute a significant public health problem, especially among the elderly population. The aim of the research was to determine the level of vitamin 25 (OH) D and vitamins from group B in the chronically ill elderly in domiciliary care, depending on functional capacity and coexisting diseases. Materials and method. The pilot study included 137 patients staying in long-term domiciliary care. Samples of the participants' venous blood was obtained for laboratory tests. Centrifuged serum was used to determine the level of the following biochemical parameters: vitamin 25 (OH)D, B12, folic acid and total protein, albumin, triglycerides, total cholesterol and HDL cholesterol. Assessment of the functional status of patients was made by using the Barthel scale. Results. More than ¾ of the patients with functional deficit (according to Barthel's score 0-85 points) were deficient in vitamin 25 (OH)D, while folic acid values were below the reference values in more than half of the patients. Respondents with lower functional efficiency were characterised by a reduced average value of vitamin 25 (OH)D and folic acid. Conclusions. The studied group of the chronically ill elderly was characterised by a deficiency of vitamin D3 and folic acid. Subjects with a functional impairment deficit show a reduced mean value of vitamin 25 (OH)D and folic acid in the blood serum, compared to the group of patients with higher mobility.

Objective: To compare the prevalence of vitamin D deficiency and fracture history in nursing home residents and community-dwelling elderly subjects and to explore the association of vitamin D levels with various characteristics. Materials and methods: Sixty-six nursing home residents and 139 community-dwelling elderly subjects participated. Marital status, medical history, medication including vitamin D supplements, smoking, past fractures were assessed. Weight and height were measured and body mass index calculated. Serum 25-hydroxyvitamin D (25-OHD), PTH, Ca, phosphate, creatinine and eGFR were determined. Results: In the nursing home residents 25-OHD was lower

The influence of renal function on vitamin D metabolism in the very elderly

Abstract: Exposure to sunshine and an active lifestyle were correlated with higher 25-OH-vitamin D levels in older adults without CKD. The PTH level in patients with CKD may be influenced by the season.
