What is the best plan for antiretroviral therapy?
A 69-year-old man with chronic lung disease is hospitalized in January with 2 days of fever, cough, and hypoxemia. PCR is positive for influenza A. He received influenza vaccine 3 months ago. Symptoms began about 60 hours before admission. What treatment approach is most appropriate?
A 41-year-old man with HIV had toxoplasmic encephalitis 18 months ago. He completed therapy and has been on secondary prophylaxis. His CD4 count has been above 250/mm3 for 9 months and HIV RNA remains undetectable. MRI shows only stable scars. What is the best plan for toxoplasma suppression?
