When ALT rises to more than 500 IU/L, causes are usually from the liver. It can be due to hepatitis, ischemic liver injury, and toxins that causes liver damage. The ALT levels in hepatitis C rises more than in hepatitis A and B. Persistent ALT elevation more than 6 months is known as chronic hepatitis.
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.
While in general creatine supplementation resulted in slightly elevated creatinine levels that remained within normal limits, supplementation did not induce renal damage (P value< 0.001). Special populations included in the 2019 Systematic review included type 2 diabetic patients [ 73 ] and post-menopausal women, [ 74 ] bodybuilders, [ 75 ...
Heart disease, high blood pressure, anemia [3] [4] Duration: Long-term [5] Causes: Diabetes, heart failure, high blood pressure, glomerulonephritis, polycystic kidney disease [5] [6] Risk factors: Smoking, genetic predisposition, low socioeconomic status [7] Diagnostic method: Blood tests, urine tests [8] Treatment
The age term is (140 – age). This means that a 20-year-old person (140 – 20 = 120) will have twice the creatinine clearance as an 80-year-old (140 – 80 = 60) for the same level of serum creatinine. The C-G equation assumes that a woman will have a 15% lower creatinine clearance than a man at the same level of serum creatinine.
The serum level of calcium is closely regulated within a fairly limited range in the human body. In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone , vitamin D and the calcium sensing receptor. [ 1 ]
Acute high dose exposure typically causes manganism and the globus pallidus is the primary target. Chronic, low-level exposure extends Mn deposition and toxicity to other brain regions, including the substantia nigra.
Serum creatinine is measured to assess for the presence of kidney disease, which can be either the cause or the result of hypertension. [ 30 ] eGFR can also provide a baseline measurement of kidney function that can be used to monitor for side effects of certain anti-hypertensive drugs on kidney function.
