A 68 year old man presents with weight loss and dysphagia for 6 weeks. Upper endoscopy is shown. What is your diagnosis? #MayoIDQ and case details to follow
2/ 68M. No PMH. 6w gradual dysphagia to solids with 20 lb weight loss. No F/C/sweats. PE: cachexia. WBC 4.7 Cr 0.9 CXR normal. HBV(-). Rx fluconazole.
Per your suggestion: HIV VL 56K CD4 26. Patient willing to start ART immediately. Genotype pending. You suggest which one?
3/ Case diagnosis: Esophageal candidiasis in a man with newly diagnosed AIDS
Suggested ART: TAF-FTC-bictegravir
ART consists of 2 NRTI in combo with 3rd drug: INSTI, NNRTI or boosted PI.
Among them: INSTI is preferred for various reasons (next)
4/ ART should be individualized based on virologic efficacy, potential adverse effects, childbearing potential and use of effective contraception, pill burden, dosing frequency, drug-drug interaction potential, comorbid conditions, cost, access, and resistance test results.
5/ Among INSTI: dolutegravir or bictegravir preferred
Raltegravir has lower barrier to resistance than dolutegravir or bictegravir, it is not part of any single-tablet regimen, and have a higher pill burden than those containing dolutegravir or bictegravir.
