“…Also, serum vitamin D level did not correlate with serum CRP level (r = 0.009931, P = 0.9515). These findings agree with previous study (63). The pro-inflammatory cytokine IL-6 is linked with CRP release 68 , thus, based on this finding and our results, we believe that, vitamin D status without supplement has no effect on neither IL-6 nor its role in releasing acute phase proteins.…”

“…An earlier study indicated that, the intensity of systematic inflammation is inversely associated with vitamin D serum level 62 . Another study reported that, they did not catch any correlation among serum vitamin D level and serum IL-6, moreover they reported that, neither DAS28 score (Score of 28 joints) nor IL-6 differ significantly amid vitamin D diminish and replete groups 63 . In the light of most previous studies and our result that, IL-6 was higher in RA patients 25-OH Vit.…”

Rheumatoid arthritis (RA) is a systemic inflammatory disease with chronic nature of joints related to autoimmunity. Vitamin D was found to modulate cell growth, function of immune cells and anti-inflammatory action. The aims of that study were to investigate serum level of vitamin D and some cytokines and to identify the correlation between vitamin D and these cytokines in RA. Totally 40 RA patients without vitamin D supplement were involved in this study. Serum level of vitamin D, interleukin-6 (IL-6), IL-10, IL-35, C-reactive protein (CRP) and tumor necrosis factor α (TNF-α), all of them were measure in all patients by enzyme-linked immunosorbent assay (ELISA). Patients were classified according to Vitamin D levels into two groups; RA patients with Vit. D deficiency (n=25) and RA patients with Vit. D sufficiency (n=15). IL-6 was lower significantly (P = 0.03) in RA patients with Vit. D sufficiency than RA patients with Vit. D deficiency. IL-10 and IL-35 were higher significantly (P = 0.0234, P = 0.0356 respectively) in RA patients with Vit. D sufficiency than RA patients with Vit. D deficiency. Vit. D was significantly positively correlated with both IL-10 (r = 0.4516, P = 0.0034) and IL-35 (r = 0.3424, P = 0.0329) and negatively correlated with IL-6 (r = -0.3188, P = 0.0479). Sufficient serum level of Vit. D is correlated with higher level of anti-inflammatory cytokines (IL-10 and IL-35) and lower level of IL-6. This support the immunomodulatory effect of Vit. D in RA.

“…However, the mechanisms behind the reduced inflammation associated with vitamin D remain poorly understood. It is suggested from studies investigating rheumatoid arthritis that vitamin D may play a role in T‐cell proliferation, thereby inhibiting the expression of inflammatory cytokines such as IL‐6, IL‐17 and IL‐23 (Gopal et al ). Moreover, vitamin D can also up‐regulate the production of anti‐inflammatory cytokines (such as IL‐4, IL‐10 and IL‐13) (Larson‐Meyer ; Owens et al ).…”

The primary source of vitamin D is through synthesis in the skin, following exposure to sunlight containing ultraviolet B (UVB) radiation. Supply through skin exposure can be supplemented by the diet, but there are relatively few dietary sources, especially those which provide a large amount of vitamin D per serving. Research into the effects of vitamin D status in different population groups has become an increasingly popular topic. The current interest surrounding vitamin D research in sport remains focused on the potential ergogenic effects of vitamin D on physical performance. However, the relationship between vitamin D (dietary intake and status) and musculoskeletal health in university athlete cohorts residing at higher latitudes (>40°N) remains underinvestigated. Within this review, the possible physiological roles that vitamin D may play within sport performance for recreational and professional athletes, as well as military recruits, will be discussed. The focus will be on muscular strength, cardiovascular health and the incidence of illness, including upper respiratory tract infections. Specifically, the effect that vitamin D deficiency {defined as a plasma/serum 25‐hydroxyvitamin D [25(OH)D] concentration of <25 nmol/l} may have on musculoskeletal health, including the incidence of stress fractures, is discussed. The review also seeks to highlight avenues for future research within vitamin D and sport, in particular for populations residing at higher latitudes (>40°N) where wintertime vitamin D deficiency is prevalent. It is hoped that this review will help to raise the awareness of the importance of existing advice in the UK for the avoidance of vitamin D deficiency and international vitamin D guidelines (such as in the US) on the achievement of vitamin D sufficiency [serum 25(OH)D >50 nmol/l] for optimum health and performance in athletes, both professional and recreational.

“…15 There was no signifi cant difference in serum IL-6 levels with vitamin D levels by category in patients with rheumatoid arthritis. 16 In contrast to maternal vitamin D, unexpected results were obtained for umbilical cord vitamin D. The infant's high umbilical cord IL-6 and CRP levels were seen at normal vitamin D levels. Based on the theory, the better the vitamin D level, it is expected that IL-6 and CRP levels will tend to decrease.…”

Objective: Increased levels of inflammatory factors in newborns are often associated with lower maternal vitamin D levels. This study aimed to find out the relationship between maternal and umbilical cord vitamin D serum levels on umbilical cord Interleukin-6 (IL-6) and serum C-Reactive Protein (CRP) levels in premature infants.Methods: The study was an observational analytic, cross-sectional design in mothers who underwent preterm birth at 28-34 weeks' gestation due to premature rupture of membranes (PROM) and their infants at Dr. Cipto Mangunkusumo General Hospital (RSCM), Jakarta and Persahabatan General Hospital, Jakarta, from January 2017 to August 2018. Levels of serum vitamin D of the maternal and umbilical cord, umbilical cord IL-6 and serum CRP in premature infants were recorded. Vitamin D level was divided into deficiency (<10 ng/mL), insufficiency (10–29 ng/mL), and normal (>30 ng/mL) groups. The relationship of vitamin D levels with IL-6 and CRP was carried out using Kruskal Wallis test.Results: A total of 70 subjects met the research criteria. Umbilical cord IL-6 and serum CRP levels in premature infants of vitamin D deficient mothers were higher (20.31 pg/mL and 0.50 mg/L) compared to insufficient (3.34 pg/mL and 0.45 mg/L) and normal mothers (3.29 pg/mL and 0.30 mg/L), although not statistically significant (IL-6 p = 0.665, CRP p = 0.89). Referring to the umbilical cord blood vitamin D levels, the results were different and not as expected, in which the umbilical cord IL-6 and serum CRP levels of preterm infants in the deficiency (3.76 pg/mL and 0.35 mg/L) and insufficiency (3.37 pg/mL and 0.40 mg/L) groups were lower (IL-6) and not different (CRP) than the normal group (9.41 pg/mL and 0.40 mg/L).Conclusion: There were an increasing tendency for umbilical cord IL-6 and serum CRP levels in premature infants of vitamin D deficient mothers although these were not statistically significant. Based on the levels of vitamin D umbilical cord blood, the CRP levels in the serum of premature infants were not different, while the IL-6 levels in the deficiency and insufficiency group were lower than in the normal group.Keywords: CRP, IL-6, maternal vitamin D, umbilical cord vitamin D. Abstrak Tujuan: Peningkatan kadar faktor inflamasi pada bayi baru lahir sering dikaitkan dengan rendahnya kadar vitamin D ibu. Penelitian ini bertujuan untuk mengetahui hubungan kadar serum vitamin D ibu dan tali pusat, dengan kadar IL-6 tali pusat dan serum C-Reactive Protein (CRP) bayi prematur.Metode: Studi observasional analitik dengan desain potong lintang pada subjek ibu yang mengalami kelahiran prematur di usia 28–34 minggu kehamilan disebabkan ketuban pecah dan bayi yang dilahirkannya, di Rumah Sakit Umum Pusat Nasional dr. Cipto Mangunkusumo (RSCM) dan Rumah Sakit Umum Pusat Persahabatan, Jakarta, pada bulan Januari 2017 sampai Agustus 2018. Variabel data adalah kadar serum vitamin D ibu dan tali pusat, kadar serum IL-6 tali pusat dan kadar CRP darah bayi. Kadar vitamin D (25(OH)D) dibagi menjadi defisiensi (<10 ng/mL), insufisiensi (10–29 ng/mL) dan normal (>30 ng/mL) dan dicari hubungannya dengan kadar IL-6 tali pusat dan serum CRP bayi prematur, menggunakan uji Kruskal Wallis. Hasil: Sebanyak 70 subjek telah memenuhi kriteria penelitian. Kadar IL-6 tali pusat dan serum CRP bayi prematur dari kelompok ibu defisiensi vitamin D (20,31 pg/ml dan 0,50 mg/L) lebih tinggi dibandingkan kelompok ibu insufisiensi vitamin D (3,34 pg/mL dan 0,45 mg/L) maupun kelompok ibu normal vitamin D (3,29 pg/mL dan 0,30 mg/L) tetapi perbedaan tersebut tidak bermakna (IL-6 p=0,665 dan CRP p = 0,899). Mengacu pada kadar vitamin D darah tali pusat didapatkan hasil yang berbeda dan tidak sesuai harapan, dimana tali pusat IL-6 dan serum CRP bayi prematur mengalami defisiensi (3,76 pg / mL dan 0,35 mg / L) dan insufisiensi. (3,37 pg / mL dan 0,40 mg / L) kelompok lebih rendah (IL-6) dan tidak berbeda (CRP) dibandingkan kelompok normal (9,41 pg / mL dan 0,40 mg / L).Kesimpulan: Didapat kecenderungan peningkatan kadar IL-6 darah tali pusat dan serum CRP bayi prematur dari ibu dengan defisiensi kadar vitamin D walaupun secara statistik tidak signifikan. Berdasarkan kelompok vitamin D darah tali pusat, kadar CRP serum bayi prematur tidak berbeda, sedangkan kadar IL-6 pada kelompok defisiensi dan insufisiensi lebih rendah dibandingkan pada kelompok normal.Kata kunci: CRP, IL-6, vitamin D ibu, vitamin D tali pusat.
