Q: 42 year old male with HIV is admitted to ICU with pneumonia. ID service in the list of their regimen also prescribed an anti-hypertensive. On your inquiry, they informed you that it may help to regress his Kaposi Sarcoma (KS). Which anti-hypertensive group of drugs found to be helpful in the treatment of Kaposi Sarcoma (KS)?

A) B-Blockers
B) Diuretics
C) Calcium Channel Blockers
D) Angiotensin-Converting-Enzyme-Inhibitors (ACE-I)
E) Alpha-blockers (Hydralazine)

Answer: A

Nonselective beta-adrenergic antagonist, Timolol has shown to enhance regression of KS lesions. This treatment is derived from the efficacy of another B-Blocker, Propranolol in the treatment of infantile hemangioma, a condition similar to KS. 

 Added pearl: Another unusual treatment of KS is the application of nicotine patch, as smoking is found to be associated with a reduced risk of KS.
