Vitamin D has effects in maintaining endovascular function and regulating inflammatory activity in the vascular wall. Visceral fat is said to be a good risk predictor for vascular disease because it plays a metabolically active role and increases the release of pro-inflammatory cytokines, both of which are influential in increasing the risk of acute stroke events. Studies that discuss the correlation between these two factors are still inconsistent.  A cross-sectional study was conducted on subjects aged >18 years with acute stroke who underwent treatment at Dr. Cipto Mangunkusumo Hospital and University of Indonesia Hospital. Measurement of visceral fat levels using bioelectrical impedance analysis bedridden multifrequency. Assessment of serum vitamin D (25(OH)D) levels using chemiluminescent immunoassay method.  In a total of 73 subjects, 55 (75.3%) subjects had vitamin D insufficiency and 15 (20,5%) subject had deficiency, with mean values at 17.08±7.85 ng/mL. A total of 78.1% of subjects had high visceral fat levels. There was a significant (p<0.021) negative correlation (r= -0.271) between visceral fat and serum vitamin D levels in acute stroke. In a further multivariate analysis, visceral fat content and type of clothing (concealing clothing) was found to be the most significant factor in assessing serum vitamin D levels. There is a significant correlation between visceral fat levels and 25 (OH) vitamin D levels in acute stroke patients."

Background: Vitamin D has non-skeletal effects in maintaining endovascular function and regulating inflammatory activity in the vascular wall. Visceral fat is said to be a good risk predictor for vascular disease because it plays a metabolically active role and increases the release of pro-inflammatory cytokines, both of which are influential in increasing the risk of acute stroke events. Until now, studies that discuss the correlation between these two factors are still inconsistent. This study aims to determine the correlation between visceral fat levels and serum vitamin D levels in acute stroke patients.

Methods: A cross-sectional study was conducted on subjects aged >18 years with acute stroke who underwent treatment at Dr. Cipto Mangunkusumo Hospital and University of Indonesia Hospital during November - December 2023. Measurement of visceral fat levels using bioelectrical impedance analysis (BIA) bedridden multifrequency. Assessment of serum vitamin D (25(OH)D) levels using chemiluminescent immunoassay (CMIA) method. Bivariate and multivariate analyses were used to assess the correlation and relationship between independent and dependent variables, as well as identify other confounding factors associated with serum vitamin D levels.

Results: In a total of 73 subjects, 55 (75.3%) subjects had vitamin D insufficiency and 15 (20,5%) subject had deficiency, with mean values at 17.08±7.85 ng/mL. A total of 78.1% of subjects had high visceral fat levels. There was a significant (p<0.021) negative correlation (r= -0.271) between visceral fat and serum vitamin D levels in acute stroke. In a further multivariate analysis with linear regression for other confounding factors, only visceral fat content and type of clothing (concealing clothing) was found to be the most significant factor in assessing serum vitamin D levels.

Conclusion: There is a significant correlation between visceral fat levels and 25 (OH) vitamin D levels in acute stroke patients."

"Ulkus kaki diabetik (UKD) merupakan luka kronik pada pasien diabetes melitus (DM). Vitamin D dipercaya memiliki peran penting pada diferensiasi, proliferasi, pertumbuhan sel, dan modulasi sistem imunitas sehingga kadar yang optimal dibutuhkan untuk penyembuhan luka. Defisiensi vitamin D juga diduga mengganggu produksi dan sekresi insulin sehingga berkontribusi pada kronisitas UKD. Penelitian bertujuan membandingkan kadar vitamin D pada pasien DM dengan dan tanpa UKD; serta untuk mengetahui korelasi antara durasi UKD dan keparahan UKD berdasarkan skor PEDIS (perfusion, extension, depth, infection, sensation) dengan kadar vitamin D. Serum 25-hidroksivitamin D (25(OH)D) dianalisis menggunakan in-vitro chemiluminescent immunoassay (CLIA). Analisis statistik yang sesuai dilakukan untuk membuktikan tujuan penelitian. Perbandingan nilai median (Q1-Q3) kadar vitamin D pada pasien DM dengan dan tanpa UKD secara berurutan adalah 8,90 ng/mL (6,52-10,90) dan 16,25 ng/mL (13-19,59), serta bermakna secara statistik (p<0,001). Tidak ada korelasi antara durasi UKD dan keparahan UKD berdasarkan skor PEDIS terhadap kadar vitamin D, serta tidak bermakna secara statistik. Hasil pada penelitian ini menunjukkan bahwa kadar vitamin D pada pasien DM dengan UKD lebih rendah dibandingkan pasien tanpa UKD. Namun belum ada bukti yang cukup untuk menyimpulkan bahwa tidak ada korelasi antara durasi UKD dan keparahan UKD berdasarkan skor PEDIS terhadap kadar vitamin D.

Diabetic foot ulcers (DFU) are chronic wounds in patients with diabetes mellitus (DM). Vitamin D believed have important role in differentiation, proliferation, cell growth, and immune system modulation hence optimal levels are needed for wound healing. Vitamin D deficiency also thought to interfere insulin production and secretion, thereby contributing to DFU chronicity. This study aims to compare vitamin D levels in DM patients with and without DFU; and determine the correlation between DFU duration and severity by PEDIS (perfusion, extension, depth, infection, sensation) score to vitamin D levels. 25-hydroxyvitamin D serum analyzed using in-vitro chemiluminescent immunoassay. Appropriate statistical analysis was done following the study. Comparison of median values ​​(Q1-Q3) vitamin D levels in DM patients with and without DFU were 8.90 ng/mL (6.52-10.90) and 16.25 ng/mL (13-19.59) respectively, and statistically significant (p<0.001). There was no correlation between DFU duration and severity PEDIS score to vitamin D levels, and it was not statistically significant. The results of this study indicate that vitamin D levels in DM patients with DFU are lower than patients without DFU. However, there is not enough evidence to conclude that there is no correlation between DFU duration and severity by PEDIS score to vitamin D levels."

"Diabetes mellitus (DM) merupakan penyakit metabolik yang disebabkan berkurangnya sekresi hormon insulin, menurunnya sensitivitas insulin atau kombinasi keduanya. DM tipe2 merupakan salah satu jenis diabetes melitus yang paling banyak penyandangnya. Defisiensi vitamin D sering dikaitkan dengan kejadian DM tipe 2. Vitamin D merupakan salah satu vitamin yang berpotensi untuk memperbaiki sintesis dan sekresi insulin. Penelitian ini bertujuan untuk menilai pengaruh suplementasi vitamin D 5.000 IU/hari selama 3 dan 6 bulan terhadap fungsi sel beta pankreas yang dilihat dari penanda antioksidan (SOD), inflamasi (IL-6), PDX-1, HbA1c dan resistensi insulin (HOMA-IR) serta keamanan pemberian vitamin D yang dilihat dari peningkatan kadar 25-(OH)D dan ekspresi VDR.Penelitian ini menggunakan desain double blind randomized controlled trial mengikutsertakan 94 penyandang DM tipe 2 dengan usia 35‒80 tahun di Puskesmas Kecamatan Mampang Jakarta Selatan. Hasil randomisasi terdapat 47 subjek kelompok kontrol dan 47 subjek kelompok vitamin D. Kelompok kontrol mendapatkan plasebo sedangkan kelompok vitamin D mendapatkan plasebo dan vitamin D 5.000 IU selama 6 bulan. Studi dilakukan mulai bulan Januari─Desember 2022. SOD, IL-6, PDX-1, VDR, HbA1c, glukosa darah, insulin puasa, 25-(OH)D, HOMA-IR diperiksa pada awal penelitian, pascasuplementasi 3 dan 6 bulan. Analisis statistik dengan SPSS 20 menggunakan uji ANOVA general linear repeated measurement dan Mann Whitney.Karakteristik subjek penelitian pada kelompok vitamin D dan kelompok kontrol pada awal penelitian menunjukkan kedua kelompok setara baik pada karaktersitik demografis, laboratorium, dan asupan nutrien. Pascasuplementasi vitamin D selama 3 dan 6 bulan terdapat perbedaan bermakna kadar 25-(OH)D (p = 0,000), tidak terdapat perbedaan bermakna HbA1c dan glukosa darah (p = 0,360 dan p = 0,296) antara kelompok kontrol dan kelompok vitamin D. Terdapat perbedaan bermakna kadar insulin pasca suplementasi 3 dan 6 bulan (p = 0,034 dan p = 0,013) serta perbedaan bermakna HOMA-IR pasca suplementasi 3 dan 6 bulan (p = 0,033 dan p = 0,031) antara kelompok kontrol dan kelompok vitamin D. Kadar insulin pada kedua kelompok mengalami peningkatan tetapi peningkatan kadar insulin pada kelompok kontrol lebih tinggi. HOMA-IR pada kedua kelompok mengalami peningkatan tetapi peningkatan HOMA-IR pada kelompok kontrol lebih tinggi. Terdapatnya kadar insulin dan HOMA-IR yang lebih rendah pada kelompok vitamin D menunjukkan adanya perbaikan resistensi insulin.Untuk PDX-1 tidak terdapat perbedaan bermakna pasca suplementasi 3 dan 6 bulan (p = 0,464 dan p = 0,499) antara kelompok kontrol dan kelompok vitamin D. Vitamin D tidak terbukti meningkatkan SOD dan VDR serta tidak terbukti menurunkan IL-6.Simpulan: Suplementasi vitamin D 5.000 IU/hari selama 6 bulan dapat meningkatkan kadar 25-(OH)D dalam batas normal, serta dapat memperbaiki resistensi insulin melalui penurunan HOMA-IR dan penurunan sekresi insulin. Efek terhadap HbA1c, SOD, IL-6, PDX-1, dan VDR tidak terbukti.

Diabetes mellitus (DM) is a metabolic disease that is caused by reduced insulin secretion, reduced insulin sensitivity, or a combination of the two. Type 2 DM is one of the types of diabetes mellitus with the greatest number of cases. Vitamin D deficiency is frequently associated with the incidence of type 2 DM. Vitamin D is one of the vitamins with the potential to improve insulin synthesis and secretion. This study aimed to evaluate the effect of supplementation of vitamin D at 5.000 IU/day for 3 and 6 months on pancreatic beta cell function from the perspective of antioxidant (SOD) and inflammatory (IL-6) markers, PDX-1 expression, HbA1c concentration, and insulin resistance (HOMA-IR), and the safety of vitamin D administration as shown by 25-(OH)D concentration and vitamin D receptor (VDR) expression. This study was a double blind randomized controlled trial involving 94 patients with type 2 DM aged 35‒80 years at Mampang District Public Health Center, South Jakarta. Randomization resulted in 47 subjects in the control group and 47 subjects in the vitamin D group. The control group received placebo whereas the vitamin D group received placebo and vitamin D at 5.000 IU for 6 months. The study was conducted from January‒December 2022. SOD, IL-6, PDX-1, VDR, HbA1c, blood glucose, fasting insulin, 25-(OH)D, and HOMA-IR were determined at baseline and after supplementation for 3 and 6 months. Statistical analysis by SPSS 20 used ANOVA general linear repeated measurement and Mann-Whitney tests. Characteristics of study subjects in the vitamin D and control groups at baseline showed that both groups were similar in demographic characteristics, laboratory measures, and nutrient intake. After supplementation of vitamin D for 3 and 6 months there were significant differences in 25-(OH)D concentration (p = 0.000), but no significant differences in HbA1c and blood glucose (p = 0.360 and p = 0.296) between control and vitamin D groups. There were significant differences in insulin concentration after supplementation for 3 and 6 months (p = 0.034 and p = 0.013) and significant differences in HOMA-IR after supplementation for 3 and 6 months (p = 0.033 and p = 0.031) between control and vitamin D groups. Insulin concentrations increased in both groups but the increase insulin concentrations was higher in the control group. HOMA-IR increased in both groups but the increase in HOMA-IR was higher in the control group. The lower insulin concentrations and decreased HOMA-IR in the vitamin D group indicated improve insulin resistance. With regard to PDX-1 there were no significant differences after supplementation for 3 and 6 months (p = 0.464 and p = 0.499) between control and vitamin D groups. Vitamin D was not proven to increase SOD and VDR, and was not proven to reduce IL-6.

Conclusion: Supplementation of vitamin D at 5.000 IU/day for 6 months was able to increase 25-(OH)D concentration within normal limits and was able to improve insulin resistance through reduction in HOMA-IR and decreased insulin secretion . Effects on HbA1c, SOD, IL-6, PDX-1, and VDR were not proven."

One of many immunity system’s roles against M. leprae infection is macrophage response through its interaction with vitamin D and vitamin D receptor (VDR). The interaction between vitamin D and VDR in various immune cells will stimulate the expression of cathelicidin. The objective is to analyze the serum level of 25-hydroxyvitamin D₃ (25(OH)D) and plasma level of VDR as well as their association with IB in leprosy patients. This observational analytic study was performed with cross-sectional design. A total of 28 subjects underwent a slit-skin smear examination and then the diagnosis of leprosy was made based on the cardinal signs. This study also assessed the patient’s sun exposure with weekly sun exposure questionnaire. Serum 25(OH)D level was assessed with chemiluminescent immunoassay (CLIA) method and RVD plasma level was measured by enzyme linked immunosorbent assay (ELISA). Median serum level of 25(OH)D was 12.68 ng/ml (4.88 – 44.74). Median plasma level of VDR was 1.36 ng/ml (0.26 – 8.04). Based on multivariate regression analysis, there was no significant association between BI and serum level of 25(OH)D and plasma level of VDR (R square = 0.055). There was strong positive correlation between serum level of 25(OH)D and sun exposure score (r = 0.863; p < 0.001)."
