LEARNING OBJECTIVES TheKidney in: • Congestiveheartfailure • Liverdisease • DiabetesMellitus • SystemicVasculitis • İnfections • SystemicLupusErythematosus • Dysproteinemiasandamyloidosis • HemolyticUremicSyndrom /ThromboticThrombocyticPurpura • Canceranditstreatment
RenalFunctionIn CongestiveHeartFailure
HeartFailure • Definition -complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability to supply blood to adequatly meet the metabolic needs of bodily tissues -it is characterized by specific symptoms, such as dyspnea and fatigue, and signs, such as fluid retention
Cardiorenalsyndrome • interactionsbetween heart disease and kidney disease • the interaction is bidirectional as acute or chronic dysfunction of the heart or kidneys can induce acute or chronic dysfunction in the other organ
Classificationof Cardiorenalsyndrome • Type 1 (acute) — Acute HF results in acutekidneyinjury (AKI, previouslycalledacuterenalfailure) • Type 2 — Chroniccardiacdysfunction (eg, chronic HF) causesprogressivechronickidneydisease (CKD, previouslycalledchronicrenalfailure) • Type 3 — Abruptandprimaryworsening of kidneyfunctiondue, forexample, torenalischemiaorglomerulonephritiscausesacutecardiacdysfunction, whichmay be manifestedby HF • Type 4 — Primary CKD contributestocardiacdysfunction, whichmay be manifestedbycoronarydisease, HF, orarrhythmia • Type 5 (secondary) — Acuteorchronicsystemicdisorders (eg, sepsisordiabetesmellitus) thatcausebothcardiacandrenaldysfunction.
AcuteRI • Hepatorenalsyndrom • CronicRI • Post transplantation
Hepatorenalsyndrom • Definition development of acute kidneyinjury in a patient who usually has advanced liver disease due to cirrhosis, severe alcoholic hepatitis, or (less often) metastatic tumor, but can occur in a substantial proportion of patients with fulminant hepatic failure from any cause
DIABETIC NEPHROPATHY • Definition progressive decline in glomerular filtrationrate (GFR) in context of long-standingdiabetes, usually accompanied by nephroticrangeproteinuria and other end-organ complications,such as retinopathy
DN PATHOLOGY • Diabetic kidneys generally increased in size • Light microscopy -mesangial expansion -glomerular basement membrane thickening -glomerular sclerosis
DN PATHOLOGY Kimmelstein-Wilson nodules
DN Pathogenesis • glomerularhyperfiltration • hyperglycemiaandtheincreasedproduction of advancedglycationendproducts • increasedplasmaproreninactivity • hypoxia-inflammation • activationof cytokines
Risk factorsforprogression • family history of diabetes • black race • higher systemic blood pressures • evidence of hyperfiltration early in course of disease • poor glycemic control • smoking • obesityand older age No one factor is predictive in the individual patient

LupusNephritis • An abnormal urinalysis (hematuria and/or proteinuria) with or without an elevated plasma creatinine concentration is observed in up to 75 percent of patients with systemic lupus erythematosus • The most frequently observed abnormality is proteinuria
Classification revised by the International Society of Nephrology (ISN) and the Renal Pathology Society (RPS) • Class I – Minimal mesangiallupusnephritis • Class II – Mesangialproliferativelupusnephritis • Class III – Focallupusnephritis (activeandchronic; proliferativeandsclerosing) • Class IV – Diffuselupusnephritis (activeandchronic; proliferativeandsclerosing; segmentaland global) • Class V – Membranouslupusnephritis • Class VI – Advanced sclerosislupusnephritis
