Oxandrolone kidney function

The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ), [53] nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone). [1] Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone . [1] Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine. [54] Boldenone undecylenate and trenbolone acetate are used in veterinary medicine . [1]

A very typical case of severe cholestasis due to anabolic steroid use.  Because the steroids were being used without medical supervision, the dose and actual duration of use of each preparation was unclear, but cholestasis usually arises within 4 to 12 weeks of starting a C-17 alkylated androgenic steroid.  The jaundice can be severe and prolonged and accompanied by severe pruritus and marked weight loss.  The serum enzymes are typically minimally elevated except for a short period immediately after stopping therapy.  The pattern of enzyme elevations can be hepatocellular, cholestatic or mixed.  Liver biopsy shows a “bland” cholestasis with minimal inflammation and hepatocellular necrosis.  Ma Huang has also been implicated in cases of drug induced liver injury, but is associated with an acute hepatocellular pattern of injury.

As indicated above, ACTH is a cleavage product of the pro-hormone, proopiomelanocortin (POMC), which also produces other hormones including α-MSH that stimulates the production of melanin . A family of related receptors mediates the actions of these hormones, the MCR, or melanocortin receptor family. These are mainly not associated with the pituitary - adrenal axis. MC2R is the ACTH receptor . While it has a crucial function in regulating the adrenal, it is also expressed elsewhere in the body, specifically in the osteoblast , which is responsible for making new bone, a continual and highly regulated process in the bodies of air-breathing vertebrates. [10] The functional expression of MC2R on the osteoblast was discovered by Isales et alia in 2005. [11] Since that time, it has been demonstrated that the response of bone forming cells to ACTH includes production of VEGF , as it does in the adrenal. This response might be important in maintaining osteoblast survival under some conditions. [12] If this is physiologically important, it probably functions in conditions with short-period or intermittent ACTH signaling, since with continual exposure of osteoblasts to ACTH, the effect was lost in a few hours.
