• Present study comprehends significant role of MicroRNAs in VTE pathogenesis. • Review highlights the strengths and weaknesses of MiRNAs as biomarkers and therapeutic targets. • This review could make the way for future research and exploration in this area. Venous Thrombo-embolism (VTE) is the major preventable cause of death and disability worldwide. It has the third highest incidence rate of hospital death after coronary artery disease (CAD) and stroke. With the establishment of Virchow's triad stating the major factors responsible for VTE including stasis, hypercoagulability and endothelial dysfunction, the last decade reported number of studies regarding its diagnosis and prophylaxis. Till date the most commonly used clinical marker for its diagnosis is the D-dimer test, detecting endogenous fibrinolysis. This test often gives false positive results and has low specificity. Other markers of coagulation are being used in combination with D-dimer; however, a reliable and sensitive biomarker is still needed for early and accurate diagnosis of VTE. Non-coding regulatory RNAs such as MicroRNAs (miRNAs) are small molecules that play a significant role in RNA silencing and post-transcriptional gene expression regulation. They can specifically bind to their target genes forming silencing complex, thereby inducing degradation and altered gene expression. A wide range of miRNAs have extensively been studied in a variety of cardiovascular diseases such as CAD, stroke, myocardial infarction (MI), atherosclerosis, obstructive sleep apnoea (OSA) and other complex diseases such as cancer. It has been demonstrated that circulating miRNAs have enormous potential to function as clinical diagnostic biomarkers for many diseases. This review comprehends recent studies establishing the inevitable role of miRNAs in pathogenesis of complex diseases with special emphasis on venous thrombosis. The differential expression pattern of these miRNAs shows a strong positive correlation with the manifestation of the pathological symptoms of diseases. Systematic consolidation of different miRNAs linked to VTE in various studies could be helpful in finding accurate diagnostic markers for thrombosis and may also find its place in VTE therapeutics. However, more extensive research and confirmatory experiments are needed to establish the role of these miRNAs as biomarkers. [ABSTRACT FROM AUTHOR]

Objective: The present study was conducted to evaluate the correlation of renal functions with thyroid hormone levels in patients with undialyzed chronic kidney disease (CKD). Literature shows significant alteration in thyroid hormone function tests in CKD patients who are receiving long-standing dialysis treatment. However, not much is described in those receiving conservative management without dialysis. Although CKD is associated with an increased prevalence of primary hypothyroidism, various studies on thyroid hormone status in uremic patients have reported conflicting results. Methodology: Thyroid hormone levels and biochemical markers of renal function were estimated in 30 undialyzed CKD patients and similar number of age- and sex-matched healthy controls, followed by statistical analysis and correlation. Results: Free triiodothyronine (FT3) and free thyroxine (FT4) were found to be significantly reduced (P < 0.001 for each) in undialyzed CKD patients whereas thyroid-stimulating hormone (TSH) levels showed statistically insignificant alteration in both groups. We also observed that urea and creatinine were negatively correlated whereas creatinine clearance was positively correlated with both FT3 and FT4 having high statistical (two tailed) significance with P < 0.001. Nonsignificant correlation was seen between blood urea and TSH (r = 0.236, P = 0.069), creatinine clearance, and TSH (r = 0.206, P = 0.114 Pearson's correlation coefficient). There is just significant positive correlation between the serum creatinine values and TSH (r = 0.248, P = 0.049). Conclusions: Thyroid hormones were significantly decreased in undialyzed CKD patients as compared to healthy controls. [ABSTRACT FROM AUTHOR]
