Alpha -1- Microglobulin (α1M) as an Early Biomarker in Renal Extrahepatic Manifestations of HCV-infection

Study Overview
=================
Brief Summary
-----------------
find the role of alpha one microglobulin (as an early renal tubular biomarker) to identify and evaluate the prevalence of early renal manifestations among patients with chronic HCV and compared these patients with HCV-negative healthy individuals

Detailed Description
-----------------
Hepatitis C [HCV] infection is known to cause renal manifestations, which are discovered at a late stage when chronic kidney disease (CKD) has already occurred . HCV is both a consequence and cause of renal impairment: first, dialysis patients have an increased risk of infection related to medical procedures and, second, HCV causes pathological changes to the kidneys . HCV seems to influence both renal tubular and glomerular cells as described by different proteinuria profiles and hematuria findings. Tubular cell damage may be the earliest sign of renal dysfunction caused by HCV and could potentially be used to identify patients with risk for progression. Routine urine analysis could be used to identify high risk HCV patients for early treatment. Identifying patients early is of paramount importance in order to offer a prompt intervention and to improve the prognosis in both settings, for this purposes, novel biomarkers could be used One promising biomarker is alpha-1-microglobulin (α1m), a low molecular weight glycosylated protein of molecular weight synthesized by hepatocytes, freely filtered across the glomerulus, and then reabsorbed by the proximal tubule . it can signal proximal tubule dysfunction: higher Uα1m concentrations indicate impaired tubular reabsorption . Small studies have previously shown that Uα1m concentrations increase in Acute kidney injury (AKI), reflect severity of AKI, and are associated with the need for dialysis after nonoliguric AKI . Elevated Uα1m correlates with interstitial fibrosis and tubular atrophy on kidney biopsy, representing chronic kidney damage . Furthermore, Uα1m appears to predict kidney function decline and CKD progression , Acute kidney injury risk and also associated with early tubulointerstitial renal diseases in HCV-glomerulopathy .
