Drug therapies for polymyalgia rheumatica: a pharmacotherapeutic update

Introduction: Polymyalgia rheumatica (PMR), a common disease in individuals older than 50 in the western world, is characterized by bilateral inflammatory pain involving the shoulder girdle and less commonly the neck and pelvic girdle. The main goals of the currently available treatment are to induce remission and prevent relapse.

Areas covered: This review briefly presents the main epidemiological and clinical features of PMR and discusses in depth both its classical management as well as new therapies used in PMR.

Expert opinion: In general, patients with isolated PMR experience a rapid response (in less than seven days) to 12.5–25 mg/prednisone/day. Methotrexate is the conventional disease-modifying antirheumatic drug most commonly used for disease management, especially for relapses of the disease. However, this agent often yields a modest effect. Randomized controlled trials do not support the use of antitumor necrosis factor agents in PMR. Several case series and retrospective studies have highlighted the efficacy of the anti-interleukin-6 receptor antibody tocilizumab in PMR. However, controlled trials are needed to fully establish the efficacy of this biologic agent in PMR. The potential beneficial effect of the Janus-kinase inhibitors remains to be determined.     

Characterization of actions taken during the delivery of medication therapy management: A time-and-motion approach

Objectives

To characterize actions performed by pharmacists and support staff during provision of medication therapy management (MTM) and to compare actions performed according to practice characteristics.

Medication management in Minnesota schools: The need for school nurse–pharmacist partnerships

Background

Pharmacist participation in school medication management (MM) is minimal. School nurses are responsible for increasingly complex medication administration and management in schools.

Protein corona and phospholipase activity drive selective accumulation of nanomicelles in atherosclerotic plaques

ApoB-100 and Phosphatidylcholine-specific phospholipase C (PC-PLC) are important contributors to atherosclerosis development. ApoB-100 is the main structural protein of LDL, being directly associated with atherosclerosis plaque generation. PC-PLC is highly expressed in atherosclerosis lesions and contributes to their progression. We show how phosphatidylcholine-coated nanomicelles can be used for specific characterisation of atherosclerosis plaque. Results show that ApoB-100 in the protein corona of the nanomicelle targets the particles to atherosclerotic areas in apolipoprotein E^?/? mice. Furthermore, PC-PLC selectively removes the polar heads from the phospholipid coating of the nanomicelles leading to their accumulation. To fully characterise the behaviour of the nanomicelles, we developed multimodal probes using a nanoemulsion step. Hybrid imaging revealed plaque accumulation of the nanomicelles and colocalisation with PC-PLC expression and ApoB-100 in the plaque. This study shows how protein corona composition and enzyme-driven nanomaterial accumulation can be used for detection of atherosclerosis.
