This alternative preparation did not alter long-term outcomes and represents a viable option for patients who do not have oral access. Due to tretinoin's known teratogenicity, this capsule should not be crushed, cut, or open, which limits its use in patients without oral access. Alternative routes of administration, such as via a nasogastric tube or sublingually, have not been safe and effective.

Sustained immune dysregulation and delayed immune recovery, in addition to immune cell exhaustion, may contribute to persistence of infection in the spleen. Eliminating HIV from this secondary lymphoid organ will require a thorough understanding of antiretroviral (ARV) pharmacology in the spleen, which has been minimally investigated. Low ARV exposure within the spleen may hinder the achievement of a functional or sterilizing cure if cells are not protected from HIV infection. In this study, we provide an overview of the anatomy and physiology of the spleen, review the evidence of the spleen as a site for persistence of HIV, discuss the consequences of persistence of HIV in the spleen, address challenges to eradicating HIV in the spleen, and examine opportunities for future curative efforts.Purpose Large meta-analyses demonstrate the noninferiority of laser enucleation to transurethral resection o
