Calcineurin inhibitors (CNI), including oral cyclosporin A and tacrolimus, are intensive immunosuppressants that are extensively used in the treatment of rheumatic and immunologic diseases in China. CNI selectively inhibit the activation and proliferation of T lymphocytes and the transcription of cytokines [such as tumor necrosis factor-α, interleukin (IL)-6, and IL-17] through inhibiting the activation of calcineurin in cells and reducing the release of IL-2. To standardize the use of CNI in the field of rheumatic and immunologic diseases, this consensus statement was developed by the National Clinical Research Center for Dermatologic and Immunologic Diseases (Peking Union Medical College Hospital), in conjunction with the Chinese Association of Rheumatology and Immunology Physicians, the Chinese Research Hospital Association, the Rheumatology and Immunology Professional Committee, and the Chinese Association of Rehabilitation Medicine. The 2011 Oxford Centre for Evidence-Based Medicine Levels of Evidence was used to rate the quality of the evidence and the strength of the recommendations, and the RIGHT (Reporting Items for practice Guidelines in HealThcare) checklist was followed to report the consensus. The consensus offers recommendations addressing nine clinical challenges to Chinese clinicians. The primary objective of this consensus is to deliver scientific and detailed guidance on CNI for Chinese clinicians, and to improve the quality of patient-centered medical services.

This article emphasized the problems about toxic herbs in the process of research and development of new traditional Chinese medicine (TCM). It describe and explain what the researchers should pay attention to, such as processing, the usage and dosage, quality control of the toxic herbs, and chronic in toxicity trial, course of treatment, choice and detection of safe target in clinical trial about preparation of the new TCM. The goal is to lead the researchers to attach the importance of toxic herbs in the new TCM.

Tofacitinib is a Janus kinase inhibitor and can block the Janus kinase-signal transducer and activator of transcription signal transduction pathway and reduce the production and release of a variety of cytokines. It has great potential in the treatment of various rheumatic diseases with a rapid onset of action and can reduce corticosteroid dependence and related adverse events. The therapeutic effect of tofacitinib in adult patients has been confirmed, and it has been increasingly used in pediatric patients in recent years. This article reviews the clinical application of tofacitinib in the treatment of pediatric autoimmune diseases.

The ongoing pandemic in Singapore is part of a global pandemic caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To control the spread of COVID-19 and prevent the healthcare system from being overwhelmed, 'circuit breaker' measures were introduced between 7 April and 1 June 2020 in Singapore. There is thus a crucial need for innovative approaches to the provision and delivery of healthcare in the context of safe-distancing by harnessing telemedicine, especially for patients with chronic diseases who have traditionally been managed in tertiary institutions. We present a summary of how the Virtual Monitoring Clinic has benefited the practice of our outpatient rheumatology service during the COVID-19 pandemic. The virtual consultations address the need for safe-distancing by limiting face-to-face appointments and unnecessary exposure of patients to the hospital where feasible. This approach ensures that the patients are monitored appropriately for drug toxicities and side-effects, maintained on good disease control, and provided with patient education.

The complex interaction of molecules within a biological system constitutes a functional module. These modules are then acted upon by both internal and external factors, such as genetic and environmental stresses, which under certain conditions can manifest as complex disease phenotypes. Recent advances in high-throughput biological analyses, in combination with improved computational methods for data enrichment, functional annotation, and network visualization, have enabled a much deeper understanding of the mechanisms underlying important biological processes by identifying functional modules that are temporally and spatially perturbed in the context of disease development. Systems biology approaches such as these have produced compelling observations that would be impossible to replicate using classical methodologies, with greater insights expected as both the technology and methods improve in the coming years. Here, we examine the use of systems biology and network analysis in the study of a wide range of rheumatic diseases to better understand the underlying molecular and clinical features.

BACKGROUND: We assessed the efficacy of serial interferon-gamma release assays (IGRAs) for the diagnosis of latent tuberculosis infection (LTBI) in patients receiving immunosuppressive agents for treatment of rheumatic diseases in Korea. METHODS: Of 276 patients who underwent consecutive screening with one of two IGRAs [QuantiFERON-TB Gold or QuantiFERON-TB Gold In-Tube], 66 patients were evaluated by the serial IGRA for detection of LTBI during therapy with immunosuppressive agents. Information on clinical diagnosis, medication, previous TB, blood cell count, tuberculin skin test, and interferon-gamma (IFN-gamma) level measured by IGRA was collected. RESULTS: Of the 66 patients, the initial IGRA was positive in 24.2%, negative in 65.2%, and indeterminate in 10.6%. Forty-six patients (69.7%) showed consistent IGRA results during follow-up, and 13 patients (19.7%) had consistently positive results. IGRA conversion rate was 12.1% (8/66) and reversion rate was 4.5% (3/66). Conversion of IGRA results was only observed in ankylosing spondylitis patients, and the median interval between the two tests in patients with conversion was 8.5 months. The mean IFN-gamma level in the group of patients with consistently positive IGRA results was higher than that in the group with inconsistently positive results, although this trend was not statistically significant (P=0.293). Indeterminate results were observed most frequently in patients with systemic lupus erythematosus. CONCLUSIONS: In patients receiving immunosuppressive agents, both IGRA conversions and reversions were observed. Serial IGRA testing may not be needed in patients with a positive initial IGRA result showing high IFN-gamma levels, because of high consistency in the test results.
