Abstract Background Chronic kidney disease (CKD) and immunosuppression, such as in renal transplantation (RT), stand one of the established potential risk factors for severe coronavirus 2019 (COVID-19). Case morbidity mortality rates any type infection have always been much higher CKD, haemodialysis (HD) RT patients than general population. A large study comparing COVID-19 outcome moderate to advanced CKD (Stages 3–5), HD with a control group is still lacking. Methods We conducted...

<b>Background:</b> Omentin-1, a novel adipokine identified in visceral adipose tissue, is negatively correlated with different conditions such as diabetes, obesity and inflammation. However, changes serum Omentin levels associated the degree of renal dysfunction metabolic risk factors CKD patients has not yet been revealed. In present study, we aimed to investigate level Omentin-1 related para­meters diabetic non-diabetic patients. <b>Methods:</b> 64 (30 diabetic, 34 non-diabetic) 27 healthy...

&lt;b&gt;&lt;i&gt;Background/Aims: &lt;/i&gt;&lt;/b&gt;Fabry disease is a treatable cause of chronic kidney (CKD) characterized by genetic deficiency α-galactosidase A. European Renal Best Practice (ERBP) recommends screening for Fabry in CKD patients. However, this based on expert opinion and there are no reports the prevalence stage 1-5 CKD. Hence, we investigated patients not receiving renal replacement therapy. &lt;b&gt;&lt;i&gt;Methods: &lt;/i&gt;&lt;/b&gt;This prospective study...

Hyperhomocysteinemia is considered to be an independent risk factor for atherosclerotic heart disease, including coronary artery disease (CAD). It already known that overt hypothyroidism gives rise a slight hyperhomocysteinemia. However, the effects of subclinical on levels homocysteine are not known. In this study, we have evaluated and effect L‐thyroxine treatment in patients with hypothyroidism. For purpose study selected 33 women diagnosis but without clinical CAD. After euthyroidism...
