Emerging treatment for Sjögren's disease: a review of recent phase II and III trials

INTRODUCTION

Sjögren's Disease, SjD, is a systemic autoimmune disorder characterized by reduced function of the salivary and lacrimal glands. Patients suffer from dryness, fatigue, and pain and may present with or without extra-glandular organ involvement. Symptoms limit SjD patients' quality of life and are the most difficult to improve with therapy. SjD patients are heterogeneous and clustering them into biologically similar subgroups might improve the efficacy of therapies. The need for therapies that address both the symptoms and extra glandular organ involvement of SjD presents an unmet opportunity that has recently attracted a growing interest in the pharmaceutical industry.

AREAS COVERED

The goal of this report is to review recent phase II/III studies in SjD. To accomplish our goal, we performed a literature search for phase II/III studies and abstracts recently presented at conferences.

EXPERT OPINION

This review allows updates the reader on the multitude of recent phase II/III clinical trials. We speculate on how subtypes of SjD will drive future therapeutic targeting and inform pathogenesis.

Are patients with rheumatic diseases on immunosuppressive therapies protected against preventable infections? A cross-sectional cohort study

Objective

To evaluate the prevalence of infections, prevalence of hospitalisation due to infections, the vaccination status and perceived screening of infections prior to the start of biologic disease modifying antirheumatic drugs (bDMARDs) of a patient cohort with chronic inflammatory rheumatic diseases (CIRD).

Methods

Consecutive CIRD patients reporting to our specialised centre were prospectively included (n=975) in this cross-sectional study. Data on comorbidities including infections, treatment, vaccination status, screening for latent tuberculosis infection (LTBI) and hepatitis B (HepB) were collected. Antibodies against measles and HepB were measured by ELISA. The vaccination status was assessed by a predefined vaccination score (0–26) categorising patients into four immunisation states: low (0–6), moderate (7–13), good (14–20), high (21–26).

Results

All patients on bDMARDs (n=499) were screened for LTBI, and 469 for HepB (94%). All LTBI patients (n=16) received isoniazid (3.2%) and 16 chronic HepB patients received lamivudine (3.4%). Protective measles specific IgG-antibodies were found in 901 patients (92.4%). Although 629 patients were educated about vaccination strategies (64.5%), only 540 showed a vaccination card (55.4%). Only 49% of patients had undergone pneumococcal vaccination and less than 30% were protected against HepB and influenza, while 7.6% have not protective antibody titres against measles. No patient met the German national vaccination recommendations requiring a complete documentation of vaccines. The mean vaccination score was 13.3±4.2 with 5.7% of patients having a low, 43.9% a moderate, 47.0% a good and 3.3% a high score.

Conclusions

The majority of CIRD patients are n0t sufficiently vaccinated against pneumococci, HepB, influenza and measles. Although CIRD patients and general practitioners regularly receive professional information about the need of vaccination, vaccination rates were low to moderate. Interdisciplinary quality projects should be planned to change that inacceptable result.

Inflammatory arthritis in patients with COVID-19

Patients with inflammatory arthritis represent a possible high-risk group to COVID-19 due to their immunosuppressive regimen designed to maintain low disease activity. Thus, substantial effort has been put forth to understand the impact of COVID-19 on these patients. Patients with rheumatic diseases as a whole do not appear to be more susceptible to acquiring COVID-19. Furthermore, immunosuppression generally did not increase the likelihood of developing severe COVID-19, with the important exception of medium and high-dose glucocorticoid use. In addition, a small number of COVID-19 patients have developed new inflammatory arthritis; whether this represents an unmasking of previous subclinical disease or a bone fide virus-induced arthritis is unclear. Nevertheless, it appears that inflammatory arthritis patients currently on immunosuppression should continue their medication to prevent future flares and limit glucocorticoid usage. While this continues to be a rapidly evolving field, these data are reassuring to both patients with and providers treating inflammatory arthritides.

[Threat of a SARS-CoV-2 endemic in a large hospital specialized in rheumatic diseases-relative all clear through consistent testing]

Die SARS-CoV-2-Pandemie hält die meisten Länder der Welt anhaltend in Atem. In Deutschland liegt die Prävalenz von SARS-CoV-2-Infektionen zwar noch unter 2 %, die Zahlen steigen aber seit Wochen auch in Deutschland wieder an. Die rheumatologische Versorgung wurde durch die 1. Welle der Pandemie vorübergehend beeinträchtigt. Wir berichten über die Infektionssituation in der größten deutschen Rheumaspezialklinik, dem Rheumazentrum Ruhrgebiet, weil es hier vor Kurzem während der 2. Welle erstmals zum Auftreten von mehreren SARS-CoV-2-Infektionen an einem Wochenende gekommen ist, was zu einer erheblichen Unruhe bei vielen Beteiligten führte. Die Situation konnte durch konsequentes Testen von Patienten und Mitarbeitern mit dem Antigenschnelltest aufgeklärt und die Lage beruhigt werden. Letztlich waren nur wenige Getestete positiv, und die Verläufe bei den Patienten blieben bis jetzt blande. Dies zeigt auch die Effektivität der seit April konsequent durchgeführten hygienischen Schutzmaßnahmen.
