Lancet Respir Med 2021 Apr 9. Epub 2021 Apr 9.

Nuffield Department of Clinical Medicine, University of Oxford, Oxford, UK; National Institute for Health Research (NIHR), Oxford Biomedical Research Centre, Oxford, UK. Electronic address:

Background: Multiple early reports of patients admitted to hospital with COVID-19 showed that patients with chronic respiratory disease were significantly under-represented in these cohorts. We hypothesised that the widespread use of inhaled glucocorticoids among these patients was responsible for this finding, and tested if inhaled glucocorticoids would be an effective treatment for early COVID-19.

Methods: We performed an open-label, parallel-group, phase 2, randomised controlled trial (Steroids in COVID-19; STOIC) of inhaled budesonide, compared with usual care, in adults within 7 days of the onset of mild COVID-19 symptoms. Read More

Gil Benard

Open Forum Infect Dis 2021 Mar 16;8(3):ofaa624. Epub 2020 Dec 16.

Laboratory of Medical Investigation Units 53 and 56, Division of Clinical Dermatology, Clinics Hospital, and Laboratory of Medical Mycology, Institute of Tropical Medicine, School of Medicine University of São Paulo, São Paulo, Brazil.

Different classifications of paracoccidioidomycosis emerged since its discovery in 1908, culminating in the proposition of a simplified and consensual one in 1987. However, by revisiting these classifications, case reports, or case series from which the authors based their own, we found many patients who did not fit in either the 1987 classification or in the correspondent natural history/pathogenesis view. In this report, the concepts of paracoccidioidomycosis infection, primary pulmonary paracoccidioidomycosis (PP-PCM), and other subclinical forms of PCM are reassessed. Read More

Inhibition of the ʟ-glutamine transporter ASCT2 sensitizes plasma cell myeloma cells to proteasome inhibitors.

Cancer Lett 2021 Jun 10;507:13-25. Epub 2021 Mar 10.

Laboratory of Experimental Medicine, Centre of New Technologies, University of Warsaw, Poland; Laboratory of Experimental Medicine, Medical University of Warsaw, Poland. Electronic address:

Proteasome inhibitors (PIs), used in the treatment of plasma cell myeloma (PCM), interfere with the degradation of misfolded proteins leading to activation of unfolded protein response (UPR) and cell death. However, despite initial strong antimyeloma effects, PCM cells eventually develop acquired resistance to PIs. The pleiotropic role of ʟ-glutamine (Gln) in cellular functions makes inhibition of Gln metabolism a potentially good candidate for combination therapy. Read More
