A patient with chronic eczema experiences increased Staphylococcus aureus skin infections. Which mechanism explains why this occurs due to impaired skin barrier function?

💡 Explanation

Eczema disrupts the skin barrier, leading to decreased production of antimicrobial peptides, which normally defend against bacteria like S. aureus. Because of this impaired defense, the risk of infection increases; therefore, the correct answer is disrupted peptide production, rather than altered lipid synthesis or filaggrin aggregation.

• A patient with liver cirrhosis experiences prolonged bleeding after a minor injury. Which mechanism explains why reduced fibrin crosslinking leads to this bleeding tendency?
• Why does inhibiting aldosterone synthesis reduce blood pressure in hypertension, even when angiotensin II levels remain high?
• Why does the proteasome system become less effective at protein aggregate clearance with aging in neurons?
• An individual presents with elevated TSH despite normal T4 levels; the pituitary gland shows no signs of tumors. Which mechanism explains why TSH remains elevated?
• A patient undergoes prolonged corticosteroid therapy; which consequence becomes most likely due to the reduced synthesis of dermal components?
