Reactive arthritis following tetanus vaccination: a case report

Reactive arthritis after vaccination against SARS-CoV-2: A case series and a mini-review

The rapid development of COVID-19 vaccines became essential for addressing the global pandemic. Reactive arthritis after vaccination has been a rare phenomenon. Here, we present a case series of three patients with joint inflammation possibly attributed to COVID-19 immunization (mRNA and live adenovirus vectored vaccine). Symptoms were alleviated using non-steroid anti-inflammatory drugs and glucocorticoids. After follow-up, the patients have not been diagnosed with any other rheumatic disease. Reactive arthritis after the COVID-19 vaccine is an unusual adverse effect and poses a negligible risk in comparison to the benefits of immunization, but it should be considered in differential diagnostics by a practicing rheumatologist who cares for patients with new-onset arthritis without apparent cause at the time of pandemic.

Reactive arthritis after COVID-19 vaccination: 17 cases

OBJECTIVES

The aim of the study is to report a series of 17 cases of ankle bi-arthritis that occurred shortly after coronavirus disease 2019 RNA vaccination, and to discuss the potential role of these vaccines in the pathogenesis of this rheumatological manifestation.

METHODS

All patients were examined in the same department and received a full work-up to investigate the usual causes of ankle bi-arthritis. No rheumatic inflammatory disease occurred after 9 months of follow-up. A post-vaccination serological follow-up in search of anti-Spike antibodies was requested for all patients.

RESULTS

All patients recovered with low dose of prednisolone within <2 months, except one who could not be weaned off CS. The level of antibodies found was very high in all patients.

CONCLUSION

The ankle bi-arthritis occurrence chronology, the follow-up and the similar clinical presentation might suggest a pathogenic role of RNA vaccination.

HLA-B27 negative reactive arthritis versus HLA-B27 positive reactive arthritis: A retrospective study

Reactive arthritis (ReA) is defined as inflammatory arthritis secondary to an extra-articular infection with a key genetic background, HLA-B27. However, to date, the diagnosis and classification remain incomplete. The study focused on the similarities and differences in clinical manifestation, imaging features, and laboratory inspection between HLA-B27 negative patients and HLA-B27 positive patients in order to provide a reference for future development of diagnostic and classification criteria. Twenty-five ReA (19 HLA-B27 negative patients and 6 HLA-B27 positive patients) were included in this retrospective study. Clinical data, including demographics, clinical symptoms, imaging features, and laboratory inspection, were collected. The chi-square test and Mann-Whitney U test were used in the analysis. HLA-B27 negative group showed more involvement of upper extremities and small joints, while HLA-B27 positive group performed more axial symptoms. No significant difference was found in imaging features (ultrasound and magnetic resonance imaging) or laboratory inspection (microbes culture and infection-related indicators) between the 2 groups. ReA patients with different genetic backgrounds show various manifestations, although they encounter similar infections.

Reactive arthritis (ReA) following the first dose of Covid-19 vaccine; A case report

Introduction: The development of vaccination against COVID-19 infection was a promising step during the battle against this pandemic; however, some vaccines were associated with some complications starting with just flu-like symptoms up to anaphylaxis; of the reported complications is joints pain. Here, we report a case who developed reactive arthritis (ReA) after receiving the first dose of the Pfizer-BioNTech Covid-19 vaccine. Case presentation: A healthy 54 years old male with no previous history of any medical condition was presented with bilateral hand and bilateral knee pain after one week of receiving his first dose of Pfizer-BioNTech Covid-19 vaccine. Clinical examination revealed swelling, tenderness, and erythema over the right index metacarpophalangeal joint and the medial aspect of the right knee. Radiographs of the hand and knee were normal. Laboratory investigations were within normal values except for an elevated ESR (15 mm/hr.) and a positive CRP titer of 48 mg/l. The symptoms entirely resolved after two weeks of non-steroidal anti-inflammatory medications. Conclusions: Although rare, however, ReA could be presented as a complication of Covid-19 vaccination, and physicians should be aware of the possibility of its occurrence.

Arthritis following COVID-19 vaccination: report of two cases

While most patients with coronavirus disease 2019 (COVID-19) present with mild or moderate symptoms, 15% may develop severe pneumonia, 5% develop acute respiratory distress syndrome (ARDS), septic shock, and multiple organ failure. Some patients may also experience arthralgia or arthritis. Cases of reactive arthritis have been reported during or after COVID-19. With the approval of the use of COVID-19 vaccines, the vaccination program was started in our country and is still continuing.Here we present two patients who developed arthritis after COVID-19 vaccination.

Microbial-derived antigens and metabolites in spondyloarthritis

Spondyloarthritis (SpA) is a group of chronic, immune-mediated, inflammatory diseases affecting the bone, synovium, and enthesis. Microbiome, the community of microorganisms that has co-evolved with human hosts, plays a pivotal role in human health and disease. This invisible "essential organ" supplies the host with a myriad of chemicals and molecules. In turn, microbial metabolites can serve as messengers for microbes to communicate with each other and in the cross-talk with host cells. Gut dysbiosis in SpA is associated with altered microbial metabolites, and an accumulated body of research has contributed to the understanding that changes in intestinal microbiota can modulate disease pathogenesis. We review the novel findings from human and animal studies to provide an overview of the contribution of individual microbial metabolites and antigens to SpA.

Reactive arthritis

Reactive arthritis (ReA) is an immune-mediated seronegative arthritis that belongs to the group of spondyloarthropathies and develops after a gastrointestinal or genitourinary system infection. The condition is considered to be characterized by a triad of symptoms (conjunctivitis, arthritis and urethritis) although a constellation of other manifestations may also be present. ReA is characterized by psoriasiform dermatological manifestations that may resemble those of pustular psoriasis and, similar to guttate psoriasis, is a post-infectious entity. Also, the articular manifestations of the disorder are similar to those of psoriatic arthritis and both conditions show a correlation with HLA-B27. These facts have led several authors to suggest that there is a connection between ReA and psoriasis, listing ReA among the disorders related to psoriasis. However, the pathogenetic mechanism behind the condition is complex and poorly understood. Bacterial antigenicity, the type of host response (i.e. Th1/Th2 imbalance) and various genetic factors (i.e. HLA-B27 etc.) play an important role in the development of the disorder. It is unknown whether all the aforementioned factors are part of a mechanism that could be similar to, or share basic aspects with known psoriasis pathogenesis mechanisms.

Application of the immunological disease continuum to study autoimmune and other inflammatory events after vaccination

In vaccine safety monitoring, the evaluation of possible autoimmune events is challenging. Developing grouping systems based on pathophysiology, instead of organ systems, may enhance our ability to identify or verify associations between vaccines and adverse immunologically mediated events in clinical trials and post-licensure surveillance. Emerging data suggest that self-directed tissue inflammation occurs along a continuum from innate immune-driven diseases to adaptive immune-driven diseases. Herein, we develop this proposed classification for the vaccination setting in which inflammatory diseases are placed along a continuum according to the two major arms of the immune system, the innate immune arm (mediated by cells including neutrophils, macrophages and complement) and the adaptive immune arm (cell-mediated and humoral response). We incorporate hypersensitivity reactions and molecular mimicry vaccine-related reactions into this mechanistic scheme. We show how this could have important implications to assess mechanisms of potential immune-mediated adverse events following vaccination.
