An update of targeted therapeutic options for primary Sjögren syndrome: current status and future development.

Expert Opin Pharmacother 2021 Jul 29:1-13. Epub 2021 Jul 29.

Laboratory of Autoimmune Diseases Josep Font, IDIBAPS-CELLEX, Barcelona, Spain.

: Primary Sjögren syndrome (pSS) is a systemic autoimmune disease that may affect 3 in 1,000 people within the general population. The therapeutic scenario is complex, and no therapy has proved to be able to modify the natural course of the disease, nor to prevent the most severe systemic complications.: Recently, the EULAR 2020 Recommendations for pSS have underlined the low level of evidence supporting efficacious therapeutic approaches, lacking a definition of specific treatment targets and being far from the 'disease modification' concept that is frequently used in other diseases.

Chronic Onset Form of Anti-HMG-CoA Reductase Myopathy.

Eur J Case Rep Intern Med 2021 8;8(7):002672. Epub 2021 Jun 8.

Service de Rhumatologie, Hôpitaux Universitaires de Strasbourg, France.

We report a case of anti-HMGCR myopathy mimicking limb-girdle muscular dystrophy in a 27-year-old male patient with no history of statin intake and presenting with a chronic onset form over 3 years. Treatment with prednisone and methotrexate was initiated with an insufficient response, so intravenous immunoglobulin was added. One year after initial treatment was started, as levels of creatine kinase (CK) were >1000 U/l, treatment with rituximab was added. Read More

Hoffmann-La Roche, Basel, Switzerland (L.G.); and Roche Products, Mississauga, ON, Canada (P.P.).

Background: Rituximab and mycophenolate mofetil are used to treat pemphigus vulgaris, but they have not been adequately compared in clinical trials.

Methods: In a randomized, controlled trial, we assigned patients with moderate-to-severe pemphigus vulgaris in a 1:1 ratio to receive intravenous rituximab (1000 mg on days 1, 15, 168, and 182) or oral mycophenolate mofetil (2 g per day), in addition to an oral glucocorticoid administered on the same tapering schedule in the two groups. The primary end point was sustained complete remission at week 52, defined as the healing of lesions with no new active lesions, as reflected by a Pemphigus Disease Area Index (PDAI) activity score of 0 (on a scale of 0 to 250, with higher scores indicating greater disease severity), for at least 16 weeks without the use of glucocorticoids.

Rituximab in Patients with Acute ST-elevation Myocardial Infarction (RITA-MI): an Experimental Medicine Safety Study.

Cardiovasc Res 2021 Mar 30. Epub 2021 Mar 30.

Division of Cardiovascular Medicine, Department of Medicine, University of Cambridge, Cambridge, UK.

Aims: In pre-clinical models of acute myocardial infarction (MI), mature B cells mobilise inflammatory monocytes into the heart, leading to increased infarct size and deterioration of cardiac function, whilst anti-CD20 antibody mediated depletion of B cells limits myocardial injury and improves cardiac function. Rituximab is a monoclonal anti-CD20 antibody targeted against human B cells. However, its use in cardiovascular disease is untested and is currently contraindicated. Read More

Preexisting and treatment-emergent autoimmune cytopenias in patients with CLL treated with targeted drugs.

Blood 2021 Jun;137(25):3507-3517

Department of Molecular Biotechnology and Health Sciences, University of Torino-Division of Hematology, Azienda Ospedaliero-Universitaria (AOU) Città della Salute e della Scienza di Torino, Turin, Italy.

Autoimmune cytopenias (AICs) affect 5% to 9% of patients with chronic lymphocytic leukemia (CLL). Targeted drugs-ibrutinib, idelalisib, and venetoclax-have a prominent role in the treatment of CLL, but their impact on CLL-associated AICs is largely unknown. In this study, we evaluated the characteristics and outcome of preexisting AICs and described the incidence, quality, and management of treatment-emergent AICs during therapy with targeted drugs in patients with CLL.

Successful desensitization and kidney transplantation in the presence of donor-specific anti-human leukocyte antigen antibodies in kidney transplant recipients.

Saudi J Kidney Dis Transpl 2020 Nov-Dec;31(6):1432-1438

Renal Transplant Unit, National Institute of Solid Organ and Tissue Transplantation, Dow University Hospital, Karachi, Pakistan.

Kidney transplantation has indisputably revamped renal medicine and restored hope among patients coming across fatal end-stage renal disease. However, sensitization of human leukocyte antigen (HLA) triggers extensive immunological fences to successful kidney transplantation and henceforth, transplant candidates are frequently demoted to the ever-growing waiting list owing to preformed donor specific antibodies (DSAs). Over the past few years, the advent of desensitization protocols has significantly overpowered the immunological barriers and enhanced the outcomes of kidney transplant recipients with DSAs against HLA.

Rituximab versus tocilizumab in anti-TNF inadequate responder patients with rheumatoid arthritis (R4RA): 16-week outcomes of a stratified, biopsy-driven, multicentre, open-label, phase 4 randomised controlled trial.

Lancet 2021 01;397(10271):305-317

Centre for Experimental Medicine and Rheumatology, Queen Mary University of London, London, UK; Department of Rheumatology, Mile End Hospital, Barts Health NHS Trust, London, UK. Electronic address:

Background: Although targeted biological treatments have transformed the outlook for patients with rheumatoid arthritis, 40% of patients show poor clinical response, which is mechanistically still unexplained. Because more than 50% of patients with rheumatoid arthritis have low or absent CD20 B cells-the target for rituximab-in the main disease tissue (joint synovium), we hypothesised that, in these patients, the IL-6 receptor inhibitor tocilizumab would be more effective. The aim of this trial was to compare the effect of tocilizumab with rituximab in patients with rheumatoid arthritis who had an inadequate response to anti-tumour necrosis factor (TNF) stratified for synovial B-cell status.
