Immunosuppressant Treatment in Rheumatic Musculoskeletal Diseases Does Not Inhibit Elicitation of Humoral Response to SARS-CoV-2 Infection and Preserves Effector Immune Cell Populations

COVID-19 has proven to be particularly serious and life-threatening for patients presenting with pre-existing pathologies. Patients affected by rheumatic musculoskeletal disease (RMD) are likely to have impaired immune responses against SARS-CoV-2 infection due to their compromised immune system and the prolonged use of disease-modifying anti-rheumatic drugs (DMARDs), which include conventional synthetic (cs) DMARDs or biologic and targeted synthetic (b/ts) DMARDs. To provide an integrated analysis of the immune response following SARS-CoV-2 infection in RMD patients treated with different classes of DMARDs we carried out an immunological analysis of the antibody responses toward SARS-CoV-2 nucleocapsid and RBD proteins and an extensive immunophenotypic analysis of the major immune cell populations. We showed that RMD individuals under most DMARD treatments mount a sustained antibody response to the virus, with neutralizing activity. In addition, they displayed a sizable percentage of effector T and B lymphocytes. Among b-DMARDs, we found that anti-TNFα treatments are more favorable drugs to elicit humoral and cellular immune responses as compared to CTLA4-Ig and anti-IL6R inhibitors. This study provides a whole picture of the humoral and cellular immune responses in RMD patients by reassuring the use of DMARD treatments during COVID-19. The study points to TNF-α inhibitors as those DMARDs permitting elicitation of functional antibodies to SARS-CoV-2 and adaptive effector populations available to counteract possible re-infections.

Relevant non-pharmacologic topics for clinical research in rheumatic musculoskeletal diseases: The patient perspective

OBJECTIVE

The research approach on rheumatic musculoskeletal diseases (RMDs) is challenging and patient involvement is an emerging issue to obtain relevant information to research. Despite growing interest in non-pharmacologic aspects of clinical research in RMDs, the patients' perspectives are currently poorly explored.

METHODS

A cross-sectional no-profit online survey was devised to identify and rank the priorities for clinical research in RMDs according to patients' perspectives. Patients were asked to rate the following topics: food/nutrition, air pollution, smoking, work activity, social participation, physical activity, emotional well-being/stress, alternative medicine, and patient-physician relationship. The survey was disseminated by ALOMAR (Lombard Association for Rheumatic Diseases) between June and October 2019.

RESULTS

Two hundred RMD patients completed the survey. The topic most rated 188 (94%) was the doctor-patient relationship, considered very or extremely important. Other topics rated as follows: psychological well-being 185 (92.5%), physical activity 155 (77.5%), nutrition, eating habits 150 (75%), alternative therapies 144 (72%), work activity 144 (72%), environmental pollution 134 (67%), social life 121 (60.5%) and cigarette smoke 119 (59.5%). The topics considered relevant were perceived to be able to influence disease symptoms. Environmental pollution and smoking were considered the most important for RMD prevention in 43.3% and 48.7% respectively.

CONCLUSIONS

This survey highlights the relevance of several unmet needs and indicates that active patient involvement is essential to design successful translational studies and improve clinical outcomes.

Patient-physician collaboration in rheumatology: a necessity

Over the past few decades, there has been significant and impressive progress in the understanding and management of rheumatic diseases. One of the key reasons for succeeding in making this progress has been the increasingly stronger partnership between physicians and patients, setting a milestone in patient care. In this viewpoint, we discuss the recent evolution of the physician-patient relationship over time in Europe, reflecting on the 'journey' from behind the clinic walls through to clinical and research collaborations at national and international level and the birth of healthcare professional and 'rheumatic' patient organisations. The role of expert patients and patient advocates in clinical and scientific committees now represents a core part of the decision-making process. In more recent years and following the recognition that the young patients, physicians and academics have a voice and needs of their own, including the need to be educated and instructed, has encouraged the establishment of youth organisations, enabling change and innovation to take place at a uniquely different level.
