Case 3: A 44-Year-Old with Unusual Changes in Physical Appearance

You answered:

D Weight gain caused by an interaction between risperidone and ritonavir.

This answer is incorrect. Although risperidone and other antipsychotic medications are known to cause weight gain, a significant interaction with ritonavir and risperidone has not been described. In addition, the risperidone-related side effects would not account for easy bruising, abdominal striae, hypertension, or worsening psychiatric symptoms.

A Worsening lipodystrophy caused by stavudine, fosamprenavir, and ritonavir.
B Cushing’s syndrome caused by an interaction between fluticasone and ritonavir.
C Adrenal insufficiency caused by an interaction between fluticasone and dapsone.
