Clinical Pharmacology — MCQs

Q: A chronic alcohol abuser is brought to hospital with complains of chronic liver diease. Which of the following you will add in the treatment?

Vitamin B1. ### ***Vitamin B1 (Thiamine)*** - Chronic alcohol use leads to **thiamine deficiency** due to inadequate dietary intake and impaired GI absorption, necessitating prophylactic oral or parenteral supplementation. - Deficiency puts the patient at high risk for **Wernicke-Korsakoff syndrome**, a potentially irreversible neurological disorder characterized by confusion, ophthalmoplegia, and ataxia. *Vitamin A* - While patients with chronic liver disease might develop deficiencies due to impaired storage, routine supplementation is generally not indicated without evidence of deficiency. - Excessive Vitamin A supplementation can be **hepatotoxic**, worsening underlying liver damage in this patient population. *Vitamin C* - Vitamin C deficiency is not a primary or immediate concern in the management of chronic alcohol-associated liver disease. - It is water-soluble but does not carry the same critical neurological risk profile associated with alcohol misuse as thiamine does. *Vitamin D* - While patients with cirrhosis are at risk for metabolic bone disease and Vitamin D deficiency, it is not the immediate, life-saving prophylaxis required upon admission. - Supplementation is typically guided by serum **25-hydroxyvitamin D levels** rather than being a mandatory first-line intervention like thiamine for preventing neurological catastrophe.
