Transient Elastograghy to Detect Non Alcoholic Fatty Liver Disease in Renal Transplantation Recipients.

Non-Alcoholic Fatty Liver Disease, Renal Transplant Complication Pre-Existing Disease

Transient Elastograghy

a. Primary (main): The presence of non alcoholic fatty liver disease in post renal transplantation recipients by non invasive methods as transient elastograghy b-Secondary (subsidiary): to evaluate if transient elastograghy could be used as a noninvasive tool as new perspective on the prediction, prevention of non alcoholic fatty liver disease in renal trasplantation recipients .

. Nonalcoholic fatty liver disease is caused by an accumulation of fat in the liver in the absence of significant alcohol intake. Nonalcoholic fatty liver disease is the most common chronic liver disorder. Chronic kidney disease defined as decreased kidney function shown by glomerular filtration rate (GFR) of less than 60 mL/min per 1•73 m2, or markers of kidney damage, or both, of at least 3 months duration, regardless of the underlying cause. Nonalcoholic fatty liver disease (and chronic kidney disease constitute a global public health problem, affecting approximately 25% and 10% of the world population, respectively. In recent years, both Nonalcoholic fatty liver disease and chronic kidney disease have shown increasing incidences. Renal transplantation has significantly improved the survival of patients with end-stage renal disease (ESRD). Despite major advancements in immunosuppressive treatment of renal transplant recipients (RTR) that significantly increased graft and patient short-term survival and lowered the incidence of rejection crises, long-term prognosis is still poor. ., Immunosuppressive drugs used in renal trasplantation increase incidence and severity of traditional cardiovascular risk factors and thus have expected effects on components of the metabolic syndrome (MS) after kidney transplantation. Other Common factors underlying the pathogenesis of and chronic allograft dysfunction may be insulin resistance, oxidative stress, activation of rennin-angiotensin system , Dyslipidemia, and inappropriate secretion of inflammatory cytokines by stereogenic and inflamed liver. NAFLD represents a liver manifestation of metabolic syndrome and it development is strongly associated with all components of MS in general population. They propose that the presence of NAFLD in RTR could be a strong predictor in cardiovascular morbidity and mortality., Wang H, Lin ZT, Yuan Y, Wu T. hypothesis that non alcoholic fatty liver disease may be associated with deteriorating graft function, causing a chronic allograft nephropathy and graft loss. Due to the high rate of corticosteroid askwith considering the strong relationship between chronic kidney disease and NAFLD, NAFLD would probably be a common disorder among kidney transplantation recipients if these patients did not receive stereogenic medications.
