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).

Drug-Induced Vanishing Bile Duct Syndrome: From Pathogenesis to Diagnosis and Therapeutics.

Semin Liver Dis 2021 Jun 15. Epub 2021 Jun 15.

Instituto de Fisiología Experimental (CONICET-UNR), Facultad de Ciencias Bioquímicas y Farmacéuticas, Universidad Nacional de Rosario, Rosario, Argentina.

The most concerned issue in the context of drug/herb-induced chronic cholestasis is vanishing bile duct syndrome. The progressive destruction of intrahepatic bile ducts leading to ductopenia is usually not dose dependent, and has a delayed onset that should be suspected when abnormal serum cholestasis enzyme levels persist despite drug withdrawal. Immune-mediated cholangiocyte injury, direct cholangiocyte damage by drugs or their metabolites once in bile, and sustained exposure to toxic bile salts when biliary epithelium protective defenses are impaired are the main mechanisms of cholangiolar damage.

Stimulus-Induced Rhythmic or Periodic Intermittent Discharges (SIRPIDs) in patients with triphasic waves and Creutzfeldt-Jakob disease.

Clin Neurophysiol 2021 May 20;132(8):1757-1769. Epub 2021 May 20.

Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.

Since the term Stimulus-Induced Rhythmic, Periodic, or Ictal Discharges (SIRPIDs) was introduced into the vocabulary of electrophysiologists/neurologists, there has been an ongoing debate about its significance, as well as its correlation with outcomes. SIRPIDs are frequently seen in patients who are critically ill from various causes. The literature reflects the findings of triphasic morphology, with the generalized periodic discharge (GPD) classification in many patients with SIRPIDs: toxic/metabolic encephalopathies, septic, and hypoxemic/hypercapnic encephalopathies, but also sharp periodic complexes in Creutzfeldt-Jakob disease and advanced Alzheimer's disease.
