Abstract:
Telomeres are repetitive sequences at the ends of chromosomes that contribute to genome stability and prevent replicative senescence. Telomere biology disorders (TBDs) encompass a spectrum of genetic conditions characterized by accelerated telomere shortening, which affects different organs, including the liver. TBD-related hepatic manifestations are often unrecognized and can range from asymptomatic liver test abnormalities to steatohepatitis, hepatopulmonary syndrome, or cirrhotic and noncirrhotic portal hypertension requiring liver transplantation. This review summarizes the current literature and aims to describe liver involvement in TBDs, highlighting diagnostic gaps and therapeutic challenges.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
