Objectives:
In patients with chronic kidney disease, sarcopenia is associated with dialysis treatment, accelerated protein catabolism, and high energy demand. Thus, this study aimed to assess the association between 25-OH vitamin D concentrations and muscle function in patients undergoing hemodialysis.
Design:
A cross-sectional study.
Setting:
Performed in a hemodialysis clinic.
Participants:
79 adult and elderly patients undergoing hemodialysis.
Measurements:
The sample was divided according to the SARC-F definition, being 55 patients allocated in the SARC-F <4 group and 24 in the SARC-F ≥4 group. Normal 25-OH vitamin D concentrations was considered when ≥30 ng/dL.
Results:
Vitamin D concentrations and number of patients with low or normal muscle function did not differ between the groups. There was no correlation between SARC-F and 25-OH vitamin D levels (r: -0.09, p=0.42).
Conclusions:
25-OH vitamin D has no association with muscle function loss in adults and elderly patients undergoing hemodialysis.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
