  • The Association Between Serum Selenium Concentration
    www.nature.com/scientificreports OPEN The association between serum selenium concentration and prognosis in patients with heart failure in a Chinese population Zhiliang Zhang1,2, Chao Chang1, Yuxin Zhang2, Zhiyong Chai2, Jinbei Li3 & Chunguang Qiu1* Whether Selenium (Se) defciency relates with adverse prognosis in Chinese patients with heart failure (HF) is still unknown. This study aimed to investigate the association of serum Se level and the outcomes of patients with HF in a Chinese population. Patients with HF and serum Se examination were retrospectively included. Baseline information were collected at patient’s frst admission. The primary and secondary outcomes were all-cause mortality and rehospitalization for HF during follow-up, respectively. The study participants were divided into quartiles according to their serum Se concentrations. The Cox proportional hazard models were adopted to estimate the association of serum Se levels with observed outcomes. A total of 411 patients with HF with a mean age of 62.5 years were included. The mean serum level of Se was 68.3 ± 27.7 µg/L. There was nonsignifcant diference of baseline characterizes between the four quartile groups. In comparison with patients in the highest quartile, those with the lowest quartile (17.40–44.35 µg/L) were associated with increased risk of all- cause mortality [adjusted hazard ratios (95% CI) 2.32 (1.43–3.77); Ptrend = 0.001]. Our study suggested that a lower serum Se level was signifcantly associated with increased risk of all-cause mortality in patients with HF. Heart failure (HF) is an important disease burden worldwide with a 1–2% prevalence among global population1.

  • A Brief Review and a Case Report of Selenium Responsive Cardiomyopathy Abdulrahman Al-Matary1*, Mushtaq Hussain1,2 and Jaffar Ali3,4
    Al-Matary et al. BMC Pediatrics 2013, 13:39 http://www.biomedcentral.com/1471-2431/13/39 CASE REPORT Open Access Selenium: a brief review and a case report of selenium responsive cardiomyopathy Abdulrahman Al-Matary1*, Mushtaq Hussain1,2 and Jaffar Ali3,4 Abstract Background: The authors review the role of selenium and highlight possible low selenium levels in soil that may result in deficient states in Saudi Arabia. Case presentation: The authors report a case of selenium-responsive cardiomyopathy in a 15-month old Saudi Arabian boy. This case of selenium deficiency causing dilated cardiomyopathy is presented with failure to thrive, prolonged fever and respiratory distress. The investigations revealed selenium deficiency. Selenium supplementation along with anti-failure therapy [Furosimide, Captopril] was administered for 6 months. Following therapy the cardiac function, hair, skin and the general health of the patient improved significantly. Conclusion: The patient with dilated cardiomyopathy of unknown etiology, not responding to usual medication may be deficient in selenium. Serum selenium measurements should be included in the diagnostic work-up to ensure early detection and treatment of the disease. The selenium level in the Saudi population needs be determined. Vulnerable populations have to undergo regular selenium measurements and supplementation if indicated. Dependence on processed foods suggests that the Saudi population fortify themselves with nutrient and micronutrient supplements in accordance to the RDA.

  • A Prospective Cohort Study Protocol of Gut Flora
    Li et al. BMC Cardiovasc Disord (2020) 20:481 https://doi.org/10.1186/s12872-020-01765-x STUDY PROTOCOL Open Access Risk factors for Keshan disease: a prospective cohort study protocol of gut fora Zhenzhen Li1,4, Jin Wei2,4, Yanping Zhang1,4, Gaopeng Li3, Huange Zhu1, Na Lei1, Qian He1,4, Yan Geng1,4 and Jianhong Zhu1,4* Abstract Background: Keshan disease is an endemic cardiomyopathy of undefned causes. Being involved in the unclear pathogenesis of Keshan disease, a clear diagnosis, and efective treatment cannot be initiated. However, the rapid development of gut fora in cardiovascular disease combined with omics and big data platforms may promote the discovery of new diagnostic markers and provide new therapeutic options. This study aims to identify biomarkers for the early diagnosis and further explore new therapeutic targets for Keshan disease. Methods: This cohort study consists of two parts. Though the frst part includes 300 participants, however, recruiting will be continued for the eligible participants. After rigorous screening, the blood samples, stools, electrocardiograms, and ultrasonic cardiogram data would be collected from participants to elucidate the relationship between gut fora and host. The second part includes a prospective follow-up study for every 6 months within 2 years. Finally, deep mining of big data and rapid machine learning will be employed to analyze the baseline data, experimental data, and clinical data to seek out the new biomarkers to predict the pathogenesis of Keshan disease. Discussion: Our study will clarify the distribution of gut fora in patients with Keshan disease and the abundance and population changes of gut fora in diferent stages of the disease.

ABSTRACT Keshan disease is a congestive cardiomyopathy. Dietary selenium deficiency combined with additional stressors are recognized to cause the cardiomyopathies. In this study, clinical condition of individuals with different subtypes including chronic and latent were analyzed. ECG abnormalities, chest radiography, echocardiography and blood selenium concentration were assessed. Subsequently, in effort to uncover proteins that were reliably changed in patients, isobaric tags for absolute and relative quantitation technology was applied. Bioinformatics analysis of the differentially expressed proteins were performed by means of Gene Ontology classification, KEGG pathway, and Ingenuity Pathway Analysis. ELISA experiment was used to detect the interesting proteins. As a result, chronic patients showed more EGC abnormalities compared to Latent. All patients had low blood selenium level. Proteomics data revealed 28 differentially expressed proteins.

In this study, we have aimed at determining serum selenium levels of the patients with acute myocardial infarction (A. M.I.), coronary artery disease (C.A.D), and the healthy control gro- up, and investigating whether there are any significant differences between the serum selenium levels of the healthy control group and the patients with A.M.I, and C.A.D. Mean serum selenium levels were found to be 38.59 ± 15.25 / L in the patients (n=22) with acute myocardial infarction, 37.20 ±11.44 / L in the patients (n = 27) with coronary artery disease, and 63.66 ± 11.71 / L in the healthy control group (n = 21). There was no significant differen- ce between mean serum selenium levels of the patients with A.M.I, and C.A.D (p>0.05), but significant differences have been found bet- ween the mean serum selenium levels of the healthy control group and the other two groups mentioned above.
