Oxymetholone

Abstract: The association between anabolic androgenic steroids and liver tumors was first noted in patients with Fanconi's anemia (FA). The hypotheses which led to this review were as follows: (1) androgen-treated individuals who do not have FA are also at risk of liver tumors; (2) parenteral as well as oral androgens may be responsible for liver tumors; (3) FA patients develop liver tumors after smaller and briefer androgen exposure than non-FA individuals; (4) the risk of hepatic neoplasms may depend on the specific androgen. Medline and Web of Science were searched for all cases of liver tumors associated with androgens. Information from individual cases was entered into a spreadsheet and descriptive statistical analyses were performed. Thirty-six FA cases and 97 non-FA cases with both nonhematologic disorders and acquired aplastic anemia (non-FA AA) were identified. The most common androgens were oxymetholone, methyltestosterone, and danazol. Hepatocellular carcinomas (HCC) were more often associated with oxymetholone and methyltestosterone, while adenomas were associated with danazol. Tumors were reported in six patients who received only parenteral and not oral androgens. FA patients were younger than non-FA patients when androgen use was initiated, and the FA patients developed tumors at younger ages. Non-AA patients were treated with androgens for longer periods of time, compared with FA and non-FA AA patients. All patients on anabolic androgenic steroids are at risk of liver tumors, regardless of underlying diagnosis. The magnitude of the risk cannot be determined from currently available data, because the number of patients receiving androgens is unknown.

Abstract: Anabolic androgenic steroids (AAS) are used illicitly at high doses by bodybuilders. The misuse of these drugs is associated with serious adverse effects to the liver, including cellular adenomas and adenocarcinomas. We report two very different cases of adult male bodybuilders who developed hepatocellular adenomas following AAS abuse. The first patient was asymptomatic but had two large liver lesions which were detected by ultrasound studies after routine medical examination. The second patient was admitted to our hospital with acute renal failure and ultrasound (US) studies showed mild hepatomegaly with several very close hyperecogenic nodules in liver, concordant with adenomas at first diagnosis. In both cases the patients have evolved favourably and the tumours have shown a tendency to regress after the withdrawal of AAS. The cases presented here are rare but may well be suggestive of the natural course of AAS induced hepatocellular adenomas. In conclusion, sportsmen taking AAS should be considered as a group at risk of developing hepatic sex hormone related tumours. Consequently, they should be carefully and periodically monitored with US studies. In any case, despite the size of the tumours detected in these two cases, the possibility of spontaneous tumour regression must also be taken in account.

Abstract: 134 patients with acquired aplastic anaemia (AA) were given HALG 15 mg/kg/d for 5 d and methylprednisolone for 1 month, and randomized to receive (n = 69) or not (n = 65) oxymetholone 2 mg/kg/d p.o. daily for 4 months. Early mortality ( 0.5 x 10(9)/l). The response rate at 120 d was significantly greater in patients receiving androgens (56% v 40%; P = 0.04); it was 68% v 48% (P = 0.02) in patients surviving 120 d, and 78% v 27% (P = 0.03) in females with PMN less than 0.5 x 10(9)/l. In a multivariate Cox analysis on patients with less than 0.5 x 10(9)/l PMN, the probability of responding without androgens was reduced compared to the androgen treatment arm (P = 0.05). Survival was comparable in the two groups (71% v 65%). It was superior (74% v 50%), but not significantly (P = 0.1) in females with PMN < or = 0.5 x 10(9)/l receiving androgens. Side-effects, including biochemical abnormalities and virilization, could be controlled and were reversible. In conclusion, the addition of androgens to HALG and methylprednisolone as first line treatment of aplastic anaemia significantly improves the response rate at 4 months, particularly in females with low neutrophil counts, although there is no significant effect on short-term survival. The reversible side-effects warrant the use of androgens as an adjunct to the first course of ALG in females with severe AA.
