AbstractVitamin D deficiency has been shown to be associated with anaemia. Circulating 25(OH)D consists of both epimeric and nonepimeric forms. However, the relative roles of epimeric and nonepimeric vitamin D in regulating anaemia and haemoglobin levels remain unknown. Therefore, in this study, we examined the effect of vitamin D, including its epimers, on haemoglobin levels, independently of its effect on circulating high-sensitivity C-reactive protein (hsCRP). This was a cross-sectional study of 1655 subjects from a long-term follow-up cohort at the Electricity Generating Authority of Thailand. Venous blood sample were collected for determination of vitamin D [25(OH)D2, 25(OH)D3, 3′-epi-25(OH)D2, and 3′-epi-25(OH)D3], haemoglobin, and hsCRP levels. Data are presented as mean ± standard deviation. Age, sex, and body mass index (BMI) were significantly associated with circulating haemoglobin levels, while no association was found between total serum 25(OH)D and haemoglobin levels. However, when total 25(OH)D was separated into 3′-epimeric and non-3′-epimeric forms, 3′-epi-25(OH)D was significantly associated with haemoglobin levels, independently of age, sex, and BMI (P < 0.01). No association was found between non-3′-epi-25(OH)D and haemoglobin. When hsCRP was added to the model, the effect 3′-epi-25(OH)D on haemoglobin levels remained significant (P < 0.01). In conclusion, vitamin D epimers are associated with circulating haemoglobin levels, which supports the role of vitamin D in red blood cell and iron physiology.

<p>Proses penuaan mempengaruhi peningkatan distribusi lemak abdominal dengan indikator lingkar pinggang (LP) dan rasio lingkar pinggang panggul (RLPP). Penimbunan lemak abdominal menyebabkan disfungsi jaringan adiposa sehingga mempengaruhi biomarker proinflamasi yaitu kadar serum <em>high-sensitivity C-reactive Protein</em> (hs-CRP). Penelitian bertujuan untuk mengetahui hubungan LP dan RLPP dengan kadar hs-CRP lansia wanita. Rancangan penelitian <em>cross sectional</em> pada 53 subjek dipilih secara <em>consecutive sampling</em>. Antropometri yang diukur adalah LP dan RLPP. Pengukuran kadar serum hs-CRP dianalisis dengan metode <em>enyme-linked immunosorbent assay</em> (ELISA). Wawancara yang dilakukan yaitu data diri, asupan, aktivitas fisik, dan riwayat konsumsi obat. Data asupan diperoleh dengan metode <em>food recall</em> 3x24 jam. Aktivitas fisik diperoleh menggunakan <em>International Physical Activity Questionnaire</em> (IPAQ). Analisis data digunakan uji korelasi <em>Spearman</em>. Hasil penelitian menunjukkan bahwa persentase LP pada lansia wanita yang berisiko sebesar 90,6%, RLPP yang berisiko sebesar 98,1%, dan kadar hs-CRP tinggi sebesar 30,2%. Terdapat hubungan positif antara LP dengan kadar serum hs-CRP (r=0,417 ; p=0,002). Dalam penelitian ini RLPP, aktivitas fisik, asupan energi, karbohidrat, protein, lemak, serat, vitamin A, vitamin C, vitamin D,vitamin E, dan selenium tidak berkorelasi dengan kadar hs-CRP. Simpulan penelitian ini adalah LP berkorelasi positif dengan kadar serum hs-CRP, namun RLPP tidak berkorelasi dengan kadar serum hs-CRP</p>

INTRODUCTION:Cerebrovascular accident (commonly called stroke) is dened as an abrupt onset of a neurologic decit that is attributable to a focal vascular cause. Thus, the diagnosis of stroke is clinical and laboratory studies including brain imaging are used to support the diagnosis AIMS AND OBJECTIVES: To evaluate the serum levels of high sensitivity C-reactive protein (hsCRP) in different types of cerebrovascular accidents on admission. MATERIALS AND METHODS: This study was an institution based cross-sectional study designed to investigate the association of hs-CRP levels with stroke and its types in Indian patients. The study was done in the Department of Medicine, Darbhanga Medical College and Hospital, Laheriasarai, Bihar from march 2019 to March 2020. 50 patients of either sex above 12 years of age admitted in Medicine Department of DMCH, Laheriasarai, Bihar with clinically or radiologically diagnosed stroke. RESULT: The mean level of hsCRP (mean ± s.d.) of the cases in our study was 7.65±7.01 with range 1.4 – 26 and the median was 3.7 and 58% of the cases were having level of hsCRP≥3 (p=0.023).Mean level of hsCRPof cases was signicantly higher than that of control (t98=7.25;p=0.001). CONCLUSION:We concluded that hs-CRPlevel is increased in cases of cerebrovascular accident- ischemic as well as haemorrhagic, suggesting an inammatory response in acute cerebrovascular accident. hs-CRP level is increased in patients with ischemic cerebrovascular accident dramatically but not in haemorrhagic cerebrovascular accident which might be considered as useful adjunct method for determining type of stroke in patients with cerebrovascular problems.

Background: Diabetic retinopathy (DR) is one of the major visual morbidities associated with diabetes. This study determined the levels of serum high-sensitivity C-reactive protein (hs-CRP) in patients with DR and to correlate the estimated levels of serum hs-CRP with the severity of DR and other coexisting factors.Methods: This was a cross-sectional study conducted between March 2009 and August 2010 and included patients with type 2 diabetes mellitus (T2DM) with or without DR. A detailed fundus evaluation was performed using direct and indirect ophthalmoscopy. The retinopathies were observed and documented in accordance with the Kanski's system of classification as background DR (BDR), pre-proliferative DR (PPDR), and proliferative DR (PDR). Laboratory investigations determined the levels of fasting blood glucose (FBG), postprandial blood glucose (PPBG), glycosylated hemoglobin, urine albumin excretion, and serum hs-CRP levels.Results: In total, 80 patients with T2DM were included (DR group, n=40 [BDR, n=22; PDR, n=11; PPDR, n=7]; control group, n=40). Highest serum hs-CRP levels were found in PDR group (6.68 mg/L), followed by PPDR and BDR group (3.2 mg/L and 1.56 mg/L, respectively). The PDR group showed the longest duration of diabetes (16 years), highest FBG (221.8 mg/dL) and HbA1c (6.68 mg/L). The incidence of albuminuria and maculopathy was higher in PDR group (72.7% and 54.54%, respectively). A significant association of hs-CRP levels with DR in patients with T2DM was observed. A significantly (<0.005) positive correlation of hs-CRP was also observed with age, duration of disease, FBG, PPBG, and HbA1c.Conclusions: Patients with severe grades of retinopathy had significantly higher hs-CRP levels than patients with the milder grades.

BACKGROUND: Many studies have shown that obesity was closely related to insulin resistance via several pathways such as inflammation, oxidative stress, lipolysis, and endothelial dysfunction. This study was carried out to observe the correlation between inflammation (IL-6 and hsCRP), lipolysis process (ET-1), and endothelial dysfunction (ADMA) and insulin resistance (HOMA-IR) in centrally obese men.METHODS: This was a cross sectional study on 62 male subjects aged 30–60 years old with waist circumference (WC) >90 cm. IL-6, ET-1 and ADMA levels were measured using ELISA method, while hsCRP and insulin were measured using chemiluminescence method. All blood testings were conducted in Prodia Clinical Laboratory.RESULTS: The results showed that WC was significantly correlated with hsCRP (r=0.294, p=0.022 ), ET-1 (r=0.257, p=0.047 ) and ADMA (r=0.338, p=0.009). We also found a significant correlation between hsCRP with HOMA-IR (r=0.324, p=0.021), ADMA with HOMA-IR (r=0.280, p=0.045), and IL-6 with hsCRP (r=0.437, p=0.003).CONCLUSIONS: hsCRP and ADMA have significant correlation with HOMA-IR in centrally obese men. HOMA-IR significantly increases in subjects with ADMA above median and either IL-6 or hsCRP above median, as compared to those in the other groups. Inflammation and endothelial dysfunction are important causal pathways of insulin resistance state in centrally obese men.KEYWORDS: obesity, IL-6, hsCRP, ET-1, ADMA, HOMA-IR
