Renal Function In Congestive Heart Failure
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
interactions between 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
Type 1 (acute) — Acute HF results in acute kidney injury (AKI, previously called acute renal failure) Type 2 — Chronic cardiac dysfunction (eg, chronic HF) causes progressive chronic kidney disease (CKD, previously called chronic renal failure) Type 3 — Abrupt and primary worsening of kidney function due, for example, to renal ischemia or glomerulonephritis causes acute cardiac dysfunction, which may be manifested by HF Type 4 — Primary CKD contributes to cardiac dysfunction, which may be manifested by coronary disease, HF, or arrhythmia Type 5 (secondary) — Acute or chronic systemic disorders (eg, sepsis or diabetes mellitus) that cause both cardiac and renal dysfunction.
Renal Function In Liver Disease
Acute RI Hepatorenal syndrom Cronic RI Post transplantation
Definition development of acute kidney injury 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 (DN)
Definition progressive decline in glomerular filtration rate (GFR) in context of long-standing diabetes, usually accompanied by nephrotic range proteinuria and other end-organ complications, such as retinopathy
Diabetic kidneys generally increased in size Light microscopy -mesangial expansion -glomerular basement membrane thickening -glomerular sclerosis
Kimmelstein-Wilson nodules
glomerular hyperfiltration hyperglycemia and the increased production of advanced glycation end products increased plasma prorenin activity hypoxia-inflammation activation of cytokines
family history of diabetes black race higher systemic blood pressures evidence of hyperfiltration early in course of disease poor glycemic control smoking obesity and older age No one factor is predictive in the individual patient
Renal Involvement in Systemic Vasculitis
Large vessels: aorta and its major branches and the analogous veins Medium vessels: main visceral arteries and veins and their initial branches Small vessels: intraparenchymal arteries, arterioles, capillaries, venules, and veins
Infection-Related Glomerulonephritis
Lupus Nephritis
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
Class I – Minimal mesangial lupus nephritis Class II – Mesangial proliferative lupus nephritis Class III – Focal lupus nephritis (active and chronic; proliferative and sclerosing) Class IV – Diffuse lupus nephritis (active and chronic; proliferative and sclerosing; segmental and global) Class V – Membranous lupus nephritis Class VI – Advanced sclerosis lupus nephritis
Renal Amyloidosis and Glomerular Diseases with Monoclonal Immunoglobulin Deposition
Noninfiltrated purpuric macule
Renal İnvolvementn in Hemolytic- Uremic Syndrome (HUS) / Thrombotic- Thrombocytopenic Purpura (TTP)
