[Occult thyroid dysfunction in outpatients with liver cirrhosis].

Area of Science:

• Endocrinology
• Hepatology
• Internal Medicine

Context:

• Liver cirrhosis (LC) is associated with various thyroid function alterations.
• Screening for thyroid disease is crucial in patients with LC.

Purpose:

• To screen for thyroid disease in adult patients diagnosed with liver cirrhosis.
• To analyze thyroid dysfunction prevalence based on cirrhosis etiology, MELD score, and Child-Pugh class.

Summary:

• A cross-sectional study measured thyroid-stimulating hormone (TSH) and free-tetraiodothyronine (T4) in 36% of LC patients, with subclinical hypothyroidism being the most frequent (34%).
• Alcohol-induced cirrhosis showed the highest subclinical hypothyroidism rates (45%), and elevated TSH levels were noted in autoimmune and alcohol-induced cirrhosis.
• No correlation was found between thyroid hormones and age, MELD, or C-P scores, indicating occult thyroid dysfunction is prevalent regardless of liver reserve.

Impact:

• Highlights the high prevalence of occult thyroid dysfunction in liver cirrhosis patients.
• Identifies alcohol-induced cirrhosis as a significant risk factor for subclinical hypothyroidism.
• Suggests the need for longitudinal studies to determine the clinical impact of subclinical hypothyroidism on cirrhosis progression.
