Understanding Liver Cysts
Liver cysts, also known as hepatic cysts, are fluid-filled sacs that form in the liver. Most are congenital, benign, and cause no symptoms, often discovered incidentally during imaging for other conditions. However, some can become large, numerous, or infected, leading to pain, distension, or, in rare cases, life-threatening complications. While most are benign, it's crucial to understand the causes, including the role of medication, to properly manage and mitigate risks.
Drug-induced liver injury (DILI) is a significant medical concern, with numerous medications known to cause hepatic toxicity. While many cases manifest as acute hepatitis or cholestasis, chronic or repeated exposure to certain drugs can lead to structural changes, including the formation of cysts or other lesions like peliosis hepatis.
Medications Linked to Liver Cysts
Certain medications have been linked to the development or worsening of liver cysts through various mechanisms. A primary group includes oral anabolic-androgenic steroids (AAS), particularly 17-α-alkylated versions, which are associated with peliosis hepatis, a condition involving blood-filled cysts in the liver. The risk of peliosis hepatis increases with higher doses and longer duration of AAS use and can be life-threatening if cysts rupture. Discontinuing AAS often leads to the regression of peliosis hepatis.
Hormonal therapies, specifically those containing estrogen, can also influence liver cyst growth, particularly in individuals with polycystic liver disease (PLD). Both estrogen-containing oral contraceptives and estrogen replacement therapy have been suggested to potentially increase liver volume and cyst growth in PLD patients. Estrogen is thought to promote cyst growth by stimulating the cells lining the cysts.
Some immunosuppressants and other drugs also have associations with liver health that can be relevant to cysts. While somatostatin analogs like lanreotide are sometimes used to treat PLD by reducing cyst size, their use has been linked to an increased risk of hepatic cyst infection, especially when combined with other immunosuppressants. The full impact of various medications on liver cysts, including their mechanisms and management, can be explored further in external resources.
Conclusion
Certain medications, like oral anabolic-androgenic steroids and estrogen-containing hormonal therapies, are linked to inducing or worsening liver cysts. The risk associated with anabolic steroids is often dependent on dose and duration. Discontinuing the offending medication can frequently lead to improvement. It is essential for patients to discuss all medications and supplements with their healthcare providers to assess risks and ensure proper liver health management.
