Nonscarring Scalp Alopecia: Which Laboratory Analysis Should We Perform On Whom?, Ümran Öner, Necmetti̇n Akdeni̇z
Turkish Journal of Medical Sciences
Background/aim: Vitamins and minerals are thought to play an essential but not entirely clear role in developing, preventing, and treating nonscarring alopecia. Telogen effluvium, androgenetic alopecia, and alopecia areata are the most common forms of nonscarring alopecias. We would like to present a different perspective on laboratory abnormalities in patients with nonscarring alopecia. Materials and methods: A total of 467 patients (287 females, 180 males) were included retrospectively: One hundred and sixty patients in the telogen effluvium group, 101 patients in the androgenetic alopecia group, 99 patients in the alopecia areata group, and 107 patients in the hair loss group …

Background/aim: Vitamin D levels have been investigated in children with familial Mediterranean fever (FMF), but the relationship between vitamin D status and inflammation/oxidative stress indicators could not be clearly demonstrated. This study aimed to investi- gate the relationship between subclinical inflammation/oxidative stress and vitamin D status in children with FMF during an attack-free period. Materials and methods: In the cross-sectional study, ninety children with FMF in the attack-free period and 30 healthy children were included. Patients were grouped according to their vitamin D status (< 20, 20-29, and 30-100 ng/mL). The groups were compared in terms of pentraxin 3 (PTX-3), total oxidant status (TOS), and total antioxidant status (TAS). Multivariable linear regression analysis was performed to identify factors associated with vitamin D status. Results: PTX-3 levels were significantly higher in patients with vitamin D insufficiency (20-29 ng/mL) than in the group with vitamin D sufficient (30-100 ng/mL). Patients with vitamin D deficiency (< 20 ng/mL) had higher TOS. A strong negative correlation was ob- served between vitamin D levels and TOS (p = 0.003). Subclinical inflammation (PTX-3 ≥ 0.640) and high TOS levels were negatively associated with vitamin D levels. Conclusion: Subclinical inflammation and oxidative stress were negatively associated with vitamin D levels in patients with FMF dur- ing an attack-free period. Sufficient vitamin D levels are important in fighting subclinical inflammation and oxidative stress in children with FMF.

Background/aim: To measure the expression of 1α-hydroxylase (CYP27B1) and serum 25(OH)D concentration in systemic lupus erythematosus (SLE) and to investigate the role of CYP27B1 in SLE. Materials and methods: Seventy-seven SLE patients and 35 healthy controls (HCs) were enrolled from September 2017 to January 2020. T he study design is cross-sectional. mRNA expression of CYP27B1 in peripheral blood mononuclear cells (PBMCs) was measured by reverse-transcription quantitative PCR, the protein level of CYP27B1 was quantified by western blotting, and the serum level of 25(OH) D was determined by an enzyme-linked immunosorbent assay. Results: The mRNA expression of CYP27B1 in PBMCs was …

Background/aim: Vitamin D, adropin, proinflammatory cytokines, and oxidative stress closely related with metabolic homeostasis and endothelial dysfunction. The aim of the present study is to investigate how vitamin D levels affect serum adropin, IL-1ß, IL-6, and oxidative stress. Materials and methods: A total of 77 female subjects were divided into 3 groups according to vitamin D levels. Biochemical parameters, adropin, IL-1ß, IL-6, oxidative stress markers were studied in these groups, and the results were compared statistically. Results: Serum adropin, IL-1ß, IL-6, total oxidant status (TOS) and total antioxidant status (TAS) and oxidative stress index (OSI) levels differed significantly between the …

Effects Of Vitamin D Administration At The Beginning Of Lactation In Dairy Cows Oninflammatory Response And Liver Metabolism, Feyyaz Kaya, Hasan Batmaz
Turkish Journal of Veterinary & Animal Sciences
This study aimed to investigate the effect of vitamin D administered 24 h after calving of dairy cows on calcium-phosphorus metabolism, carbohydrate, lipid and liver metabolism, and inflammatory response. Twenty multiparous Holstein cows were randomly assigned to the experimental (EG) and control group (CG). The EG received 5,000,000 IU vitamin D3 (5 mL) 24 h after parturition intramuscularly, whereas the CG group received 5 mL of 0.9% NaCl. Blood samples were taken 24 h after parturition before treatments and at the 3rd, 7th, 14th, and 28th days of lactation. Serum NEFA, BHBA, haptoglobin, serum amyloid A (SAA), ceruloplasmin, calcium, phosphorus, …

Background/aim: Vitamin D insufficiency is a common public health problem that is often unrecognized in children with congenital heart disease, and is not generally evaluated at congenital heart disease (CHD) follow-up. Recent studies have suggested that inadequate vitamin D status may have an adverse effect on cardiovascular health. This study investigates the relationship between vitamin D levels and hemodynamic parameters in children with CHD. Methods: Included in the study 40 patients (25 females, 15 males) with CHD, who were evaluated for Ross heart failure score, vitamin D, parathyroid hormone (PTH), calcium, phosphorus, alkaline phosphatase (ALP), whole blood count (WBC) and …
