Current and emerging biological therapy in adult-onset Still's disease.

Rheumatology (Oxford) 2021 Jun 12. Epub 2021 Jun 12.

Department of Rheumatology and Immunology, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Adult-onset Still's disease (AOSD) is a rare, but characteristic non-familial, multi-genic systemic auto-inflammatory disorder, characterized by high spiking fever, salmon-like evanescent skin rash, polyarthritis, sore throat, hyperferritinemia, and leucocytosis. The hallmark of AOSD is a cytokine storm triggered by dysregulation of inflammation. Nowadays, with advances in anti-cytokine biologic agents, the treatment of AOSD is no longer limited to nonsteroidal anti-inflammatory drugs (NSAIDs), glucocorticoids, or conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs).

Coexistence of immune-mediated diseases in sarcoidosis Frequency and clinical significance in 1737 patients.

Joint Bone Spine 2021 Jun 8:105236. Epub 2021 Jun 8.

Department of Medicine, Universitat de Barcelona, Barcelona, Spain; Department of Autoimmune Diseases, ICMiD, Hospital Clinic, Barcelona, Spain. Electronic address:

Objective: To analyze whether immune-mediated diseases (IMDs) occurs in sarcoidosis more commonly than expected in the general population, and how concomitant IMDs influence the clinical presentation of the disease.

Methods: We searched for coexisting IMDs in patients included in the SARCOGEAS-cohort, a multicenter nationwide database of consecutive patients diagnosed according to the ATS/ESC/WASOG criteria. Comparisons were made considering the presence or absence of IMD clustering, and odds ratios (OR) and their 95% confidence intervals (CI) were calculated as the ratio of observed cases of every IMD in the sarcoidosis cohort to the observed cases in the general population.

High risk of early sub-therapeutic penicillin concentrations after intramuscular benzathine penicillin G injections in Ethiopian children and adults with rheumatic heart disease.

PLoS Negl Trop Dis 2021 Jun 11;15(6):e0009399. Epub 2021 Jun 11.

Faculty of Health and Medical Sciences, University of Western Australia, Perth, Western Australia, Australia.

Introduction: Intramuscular benzathine penicillin G (BPG) injections are a cornerstone of secondary prophylaxis to prevent acute rheumatic fever (ARF) and rheumatic heart disease (RHD). Uncertainties regarding inter-ethnic and preparation variability, and target exposure profiles of BPG injection are key knowledge gaps for RHD control.

Methods: To evaluate BPG pharmacokinetics (PK) in patients receiving 4-weekly doses in Ethiopia, we conducted a prospective cohort study of ARF/RHD patients attending cardiology outpatient clinics. Read More

COVID-19 in patients with gout on colchicine.

Rheumatol Int 2021 Jun 5. Epub 2021 Jun 5.

Rheumatology Clinic, Department of Internal Medicine, Medical School, University of Ioannina, 45110, Ioannina, Greece.

Current data demonstrated that severe cases of coronavirus-disease-19 (COVID-19) require treatment with antiviral therapy, dexamethasone, supportive care, as well as some anti-rheumatic drugs, among them, cytokine inhibitors and colchicine. Colchicine is an anti-inflammatory drug that is being used in rheumatology for many years to treat mostly gout, calcium pyrophosphate deposition disease, and Familial Mediterranean Fever. Here, we present for the first time, two patients suffering from gout being treated with colchicine, who were affected from severe acute respiratory coronavirus-2 (SARS-CoV-2) syndrome. Read More

The assessment of mitral valve disease: a guideline from the British Society of Echocardiography.

Echo Res Pract 2021 May 1. Epub 2021 May 1.

B Rana, Cardiology, Hammersmith Hospitals NHS Trust, London, United Kingdom of Great Britain and Northern Ireland.

Mitral valve disease is common. Mitral regurgitation is the second most frequent indication for valve surgery in Europe and despite the decline of rheumatic fever in western societies, mitral stenosis of any aetiology is a regular finding in all echo departments. Mitral valve disease is therefore one of the most common pathologies encountered by echocardiographers, as both a primary indication for echocardiography and a secondary finding when investigating other cardiovascular disease processes.

In Search of the Holy Grail: A Specific Diagnostic Test for Rheumatic Fever.

Front Cardiovasc Med 2021 14;8:674805. Epub 2021 May 14.

School of Science and Technology, University of New England, Armidale, NSW, Australia.

Current diagnosis of Acute Rheumatic Fever and Rheumatic Heart Disease (ARF/RHD) relies on a battery of clinical observations aided by technologically advanced diagnostic tools and non-specific laboratory tests. The laboratory-based assays fall into two categories: those that (1) detect "evidence of preceding streptococcal infections" (ASOT, anti-DNAse B, isolation of the Group A from a throat swab) and (2) those that detect an ongoing inflammatory process (ESR and CRP). These laboratory tests are positive during any streptococcal infection and are non-specific for the diagnosis of ARF/RHD. Read More

Rheumatic Fever and Rheumatic Heart Disease in the United States.

Pediatr Ann 2021 Mar 1;50(3):e98-e104. Epub 2021 Mar 1.

During the 1920s, acute rheumatic fever (ARF) was the leading cause of mortality in children in the United States. By the 1980s, many felt ARF had all but disappeared from the US. However, although ARF and rheumatic heart disease (RHD) rates remain low in the US today, disease burden is unequal and tracks along other disparities of cardiovascular health. Read More

Requirements for a Robust Animal Model to Investigate the Disease Mechanism of Autoimmune Complications Associated With ARF/RHD.

Front Cardiovasc Med 2021 5;8:675339. Epub 2021 May 5.

School of Science and Technology, University of New England, Armidale, NSW, Australia.

The pathogenesis of Acute Rheumatic Fever/Rheumatic Heart Disease (ARF/RHD) and associated neurobehavioral complications including Sydenham's chorea (SC) is complex. Disease complications triggered by Group A streptococcal (GAS) infection are confined to human and determining the early events leading to pathology requires a robust animal model that reflects the hallmark features of the disease. However, modeling these conditions in a laboratory animal, of a uniquely human disease is challenging. Read More

Rheumatol Int 2021 May 20. Epub 2021 May 20.

Department of Rheumatology and Immunology, Hangzhou Normal University Affiliated Hospital, No. 126, Wenzhou Road, Hangzhou, 310015, China.

Adult-onset Still's disease (AOSD) is a rare systemic auto-inflammatory disease that is an exclusive diagnosis that needs to previously exclude infections, tumors, and rheumatic diseases. There are few reports on AOSD overlapping with other rheumatic diseases. We reported a 55-year-old male who presented with a high, daily spiking fever associated with an evanescent salmon-pink rash, arthralgia, and sore throat. Read More

The prevalence of enteroviral RNA and protein in mitral valves of chronic rheumatic heart disease.

J Infect Dev Ctries 2021 Apr 30;15(4):566-572. Epub 2021 Apr 30.

Department of Microbiology, Kidwai Cancer Institute, Bangalore, India.

Introduction: Acute Rheumatic Fever/ Rheumatic Heart Disease (ARF/RHD), a sequel of group A streptococcal (GAS) infection, even today constitutes a public health issue in developing countries including India. Differences in the prevalence of ARF/RHD in countries with a similar prevalence of GAS infections indicate the role of other cofactors in pathogenesis of RHD.

Methodology: We investigated the prevalence of enterovirus (EV) in RHD by probing for both EV RNA and VP1 protein using Nonisotopic In Situ Hybridization (NISH) and Immunohistochemistry (IHC) respectively in 75 valvectomy specimens obtained from RHD cases. Read More
