A 29-year-old gender nonbinary individual with HIV and a CD4 count of 128 cells/mm³ returns for a follow-up visit. They have a 4-year history of type 1 diabetes mellitus, and for the last 12 months, they have taken the same insulin regimen. They report that morning blood glucose levels have consistently ranged from 190 to 250 mg/dL, and they deny having any hypoglycemic episodes. Five months ago, they were diagnosed with HIV and started taking dolutegravir plus tenofovir alafenamide-emtricitabine and dapsone for Pneumocystis carinii prophylaxis. Their laboratory studies 5 months ago showed glycosylated hemoglobin (HbA1c) 8.2%, serum creatinine 1.1 mg/dl, and hematocrit 38%. Laboratory studies obtained at the current visit show HbA1c 5.6%, serum creatinine 1.2 mg/dL, and hematocrit 33%.
