Therapeutic review of cabotegravir/rilpivirine long-acting antiretroviral injectable and implementation considerations at an HIV specialty clinic.

Pharmacotherapy 2021 Jun 15. Epub 2021 Jun 15.

Indiana University Health, Indianapolis, Indiana, USA.

Cabotegravir/rilpivirine (CAB/RPV) was recently approved by the US Food and Drug Administration (FDA) as the first complete parenteral antiretroviral (ART) regimen for treatment of people living with HIV (PLWH). As a monthly intramuscular (IM) injection, this therapy constitutes a major departure from the traditional paradigm of oral therapy requiring (at least) daily administration that has defined HIV treatment for decades. Composed of a second-generation integrase inhibitor (INSTI) and nonnucleoside reverse transcriptase inhibitor (NNRTI), CAB/RPV has achieved high rates of sustained virologic suppression with a favorable safety profile for treatment-experienced PLWH following oral lead-in (OLI) during several clinical trials.

COVID-19 and Antiphospholipid Antibodies: Time for a Reality Check?

Semin Thromb Hemost 2021 Jun 15. Epub 2021 Jun 15.

Section of Clinical Biochemistry, University of Verona, Verona, Italy.

Antiphospholipid antibodies (aPL) comprise a panel of autoantibodies that reflect a potential prothrombotic risk in several autoimmune conditions, most notably antiphospholipid (antibody) syndrome (APS). aPL can be divided into those that form part of the laboratory criteria for APS, namely, lupus anticoagulant (LA), as well as anticardiolipin antibodies (aCL) and anti-β2-glycoprotein I antibodies (aβ2GPI) of the immunoglobulin G and M classes, and those that form a group considered as "noncriteria antibodies." The noncriteria antibodies include, for example, antiphosphatidylserine antibodies (aPS), antiprothrombin antibodies (aPT), and antiphosphatidylserine/prothrombin complex antibodies (aPS/PT).
