ABSTRACT

Idiopathic inflammatory myopathies are a group of rare, autoimmune, diseases typically involving striate muscle and also variously affecting several other systems or organs, such as joints, skin, lungs, heart and gastrointestinal tract. IIM are mainly characterised by subacute onset and chronic course and are burdened by significant morbidity and mortality. Despite the rarity of these conditions, several efforts have been undertaken in the last years to better understand their pathogenesis, as well as to achieve a more precise classification and to define the optimal therapeutic approach. The aim of this review is to provide an up-to-date digest of the most relevant studies published on this topic over the last year.

ABSTRACT

Pain remains one of the most difficult-to-treat domains in patients with rheumatoid arthritis (RA). In clinical trials, the Janus kinase inhibitors (JAKis) have demonstrated good efficacy in pain relief. Aim of our study was to evaluate the real-life effectiveness of JAKis in improving pain in patients with RA in different states of baseline disease activity. A monocentric prospective cohort of 181 RA patients starting treatment with JAKis was studied. Pain was evaluated on a 0-100 mm visual analogue scale (VAS). Clinically meaningful improvements over 24 weeks were defined as follows: proportion of patients achieving ≥ 30%, ≥ 50%, and ≥ 70% pain relief, and remaining pain ≤ 20 or ≤ 10 mm. Results were analysed after stratification for baseline inflammatory activity; patients with swollen joints and C-reactive protein ≤ 1 at treatment start were considered pauci-inflammatory. Proportion of patients who achieved ≥ 30%, ≥ 50% and ≥ 70% pain improvement at 24 weeks was 61.4%, 49.3% and 32.9%. Furthermore, 40.6% and 28.5% of the patients achieved thresholds of remaining pain equivalent to mild pain or no/limited pain. Pain improvements were more evident in patients naive to previous biologics, although nearly 30% of multiple failures achieved VAS ≤ 20 mm. No significant differences were observed in relation to monotherapy. Pauci-inflammatory patients at treatment start achieved good outcomes, with 40.4% experiencing ≥ 70% pain improvement, and 35.7% VAS ≤ 10 mm. JAKis show efficacy in pain relief in real life. The improvement of painful symptoms also in those patients with limited objective inflammation may open new perspectives on the management of difficult-to-treat RA.

ABSTRACT

Idiopathic inflammatory myopathies (IIM) are a heterogeneous group of disorders in which chronic inflammation of the skeletal muscle, leading to muscle weakness, is a common feature. Different phenotypes have been identified within the IIM spectrum based on extra-muscular manifestations, immunology, muscle histology, responsiveness to therapy, and prognosis. The pathogenesis, classification, treatment, and prognosis of the different IIM subtypes are subject to active discussion and research. This review highlights the most relevant literature published on this topic over the last year.

ABSTRACT

Capillary leak syndrome (CLS) is a rare condition characterised by increased capillary permeability, with subsequent hypoalbuminemia and hypotension, leading to an increased risk of shock and death. We present the case of a patient with anti-transcriptional intermediary factor 1γ dermatomyositis that developed CLS one week after starting treatment with rituximab and prophylactic co-trimoxazole. The patient was admitted to the Intensive Care Unit (ICU), recovered after treatment with intravenous immunoglobulin, albumin, and Ringer lactate, but died a month after the discharge due to a poorly differentiated hepatocarcinoma diagnosed in the ICU.

ABSTRACT

There is growing concern about seismicity triggered by human activities, whereby small increases in stress bring tectonically loaded faults to failure. Examples of such activities include mining, impoundment of water, stimulation of geothermal fields, extraction of hydrocarbons and water, and the injection of water, CO2 and methane into subsurface reservoirs1. In the absence of sufficient information to understand and control the processes that trigger earthquakes, authorities have set up empirical regulatory monitoring-based frameworks with varying degrees of success2,3. Field experiments in the early 1970s at the Rangely, Colorado (USA) oil field4 suggested that seismicity might be turned on or off by cycling subsurface fluid pressure above or below a threshold. Here we report the development, testing and implementation of a multidisciplinary methodology for managing triggered seismicity using comprehensive and detailed information about the subsurface to calibrate geomechanical and earthquake source physics models. We then validate these models by comparing their predictions to subsequent observations made after calibration. We use our approach in the Val d'Agri oil field in seismically active southern Italy, demonstrating the successful management of triggered seismicity using a process-based method applied to a producing hydrocarbon field. Applying our approach elsewhere could help to manage and mitigate triggered seismicity.
