Introduction
Tibolone is a synthetic estrogen used for treatment of symptoms of menopause and prevention of osteoporosis. Tibolone has been associated with rare instances of acute, clinically apparent liver injury.
Background
Tibolone (tye' boe lone) is a synthetic estrogen-like steroid hormone which acts as an agonist of multiple type I steroid receptors and thus has weak estrogenic and progestational activities as well as some androgenic properties. The parent compound has no activity, but undergoes tissue-specific metabolism via a sulfatase to an active form which provides estrogenic effects without the need for concurrent progesterone administration. Tibolone also appears to have reduced estrogenic activity in breast tissue. It has been shown to be effective against the symptoms of menopause and in prevention of postmenopausal osteoporosis; it is approved in several European countries, but not the United States. Tibolone is available as 1.25 and 2.5 mg tablets under the brand name Livial. Side effects include vaginal bleeding, abdominal pain, weight gain, bloating, breast tenderness, genital pruritus and vaginitis. Uncommon but potentially severe adverse events include an increased rate of venous thromboses and cerebrovascular ischemic stokes.
Hepatotoxicity
In large scale prospective studies, tibolone has been associated with a low rate of transient serum aminotransferase levels, being greater than 3 times the upper limit of normal in 0.9% of tibolone versus 0.2% of placebo recipients, but instances of clinically apparent acute liver injury were not reported. In Europe, where tibolone has been in clinical use, there have been isolated reports of clinically apparent liver injury arising 6 to 12 months after starting and associated with a hepatocellular pattern of serum enzyme elevations and jaundice. Reported cases were self-limited and resolved within 2 to 6 months of stopping. Immunoallergic features were not present nor were autoantibodies.
Likelihood score: C (probable cause of clinically apparent liver injury).
Mechanism of Injury
The mechanism of liver injury due to tibolone is not known. The clinically apparent liver injury has not resembled that of the cholestatic jaundice associated with estrogens and has features of idiosyncratic liver injury.
Outcome and Management
The severity of liver injury due to tibolone has varied from mild, transient serum enzyme elevations to moderately severe acute hepatitis. No instances of acute liver failure, death, or chronic hepatitis have been linked to tibolone use. A single instance of vanishing bile duct syndrome was reported after tibolone use in combination with St. John’s wort. Rechallenge studies have not been done.
