Clostridium difficile associated reactive arthritis: Case report and literature review

Leaky gut, circulating immune complexes, arthralgia, and arthritis in IBD: coincidence or inevitability?

Most host-microbiota interactions occur within the intestinal barrier, which is essential for separating the intestinal epithelium from toxins, microorganisms, and antigens in the gut lumen. Gut inflammation allows pathogenic bacteria to enter the blood stream, forming immune complexes which may deposit on organs. Despite increased circulating immune complexes (CICs) in patients with inflammatory bowel disease (IBD) and discussions among IBD experts regarding their potential pathogenic role in extra-intestinal manifestations, this phenomenon is overlooked because definitive evidence demonstrating CIC-induced extra-intestinal manifestations in IBD animal models is lacking. However, clinical observations of elevated CICs in newly diagnosed, untreated patients with IBD have reignited research into their potential pathogenic implications. Musculoskeletal symptoms are the most prevalent extra-intestinal IBD manifestations. CICs are pivotal in various arthritis forms, including reactive, rheumatoid, and Lyme arthritis and systemic lupus erythematosus. Research indicates that intestinal barrier restoration during the pre-phase of arthritis could inhibit arthritis development. In the absence of animal models supporting extra-intestinal IBD manifestations, this paper aims to comprehensively explore the relationship between CICs and arthritis onset via a multifaceted analysis to offer a fresh perspective for further investigation and provide novel insights into the interplay between CICs and arthritis development in IBD.

[History of reactive arthritis. Historical milestones and future]

The introduction of the term reactive arthritis (ReA) for the joint inflammation observed after infection with Yersinia enterocolitica, in which "a causative pathogen cannot be isolated from the synovial fluid", and the association with the HLA-B27 were the historical milestones for a new classification and assignment to the spondylarthritides (SpA). The division into postinfectious and reactive arthritis proposed in 1976 was put into perspective in the 1990s because of investigations with the newly available molecular biological method of the polymerase chain reaction. Microbial products could be identified from joint samples of patients with ReA. Therefore, it was proposed to abandon the distinction between the two groups of diseases and to prefer the term ReA for both. This created a terminological and nosological issue. On the one hand, there are generally accepted classification and diagnostic criteria for the classical HLA-B27-associated ReA that are assigned to SpA. On the other hand, an increasing number of bacterial pathogens, viruses, amoebas, helminths as well as antiviral and antibacterial vaccinations are described as triggers of arthritis, which have been published under the term ReA. Since the beginning of the SARS-CoV‑2 pandemic, cases of acute post-COVID-19 arthritis have been described, which were also classified as ReA because of comparable clinical features.

A Case Report and Review of the Literature: Reactive Arthritis Caused by Clostridioides difficile ribotype 027

With an annual incidence of 250-300 per 100,000 inhabitants, reactive arthritis is not uncommon. However, the fact that Clostridioides difficile infection (CDI) can also lead to this complication is largely unknown. We report on a 69-years-old man who developed reactive arthritis of his right knee joint one week after antibiotic-associated diarrhea with evidence of C. difficile of the hypervirulent ribotype 027. His female partner also became infected with C. difficile ribotype 027, but did not develop reactive arthritis. The further investigation showed that the patient - in contrast to his partner - was HLA-B27 positive and had strong antibody levels against C. difficile. The case history together with the review of 45 other cases described so far shows that C. difficile can also lead to reactive arthritis. C. difficile-associated reactive arthritis (CDARA) is characterized by the fact that patients suffer from diarrhea or colitis after taking antibiotics, toxigenic C. difficile or only the toxins are detectable in the stool and there are no other explanations for the arthritis and diarrhea.

Reactive Arthritis Update: Spotlight on New and Rare Infectious Agents Implicated as Pathogens

Purpose of Review

This article presents a comprehensive narrative review of reactive arthritis (ReA) with focus on articles published between 2018 and 2020. We discuss the entire spectrum of microbial agents known to be the main causative agents of ReA, those reported to be rare infective agents, and those reported to be new candidates causing the disease. The discussion is set within the context of changing disease terminology, definition, and classification over time. Further, we include reports that present at least a hint of effective antimicrobial therapy for ReA as documented in case reports or in double-blind controlled studies. Additional information is included on microbial products detected in the joint, as well as on the positivity of HLA-B27.

Recent Findings

Recent reports of ReA cover several rare causative microorganism such as Neisseria meningitides, Clostridium difficile, Escherichia coli, Hafnia alvei, Blastocytosis, Giardia lamblia, Cryptosporidium, Cyclospora cayetanensis, Entamoeba histolytica/dispar, Strongyloides stercoralis, β-haemolytic Streptococci, Mycobacterium tuberculosis, Mycoplasma pneumoniae, Mycobacterium bovis bacillus Calmette-Guerin, and Rickettsia rickettsii. The most prominent new infectious agents implicated as causative in ReA are Staphylococcus lugdunensis, placenta- and umbilical cord–derived Wharton’s jelly, Rothia mucilaginosa, and most importantly the SARS-CoV-2 virus.

Summary

In view of the increasingly large spectrum of causative agents, diagnostic consideration for the disease must include the entire panel of post-infectious arthritides termed ReA. Diagnostic procedures cannot be restricted to the well-known HLA-B27-associated group of ReA, but must also cover the large number of rare forms of arthritis following infections and vaccinations, as well as those elicited by the newly identified members of the ReA group summarized herein. Inclusion of these newly identified etiologic agents must necessitate increased research into the pathogenic mechanisms variously involved, which will engender important insights for treatment and management of ReA.

Reactive arthritis: an unusual presentation of acute Clostridioides difficile colitis

A 20-year-old Caucasian man with a history of psoriasis presented to the emergency department due to a 2-week history of severe polyarthralgia and a 3-week history of non-bloody diarrhoea. The initial workup 2 days prior in an urgent care clinic returned negative for all enteric pathogens including Clostridioides difficile nucleic acid amplification test. Investigations revealed colitis on CT and pseudomembranous colitis on colonoscopy. The aspirate returned positive for C. difficile toxin. Tissue biopsies of the ascending, transverse, sigmoid colon and rectum were negative for chronicity to suggest inflammatory bowel disease with extraintestinal manifestation as the aetiology of polyarthralgia, which had been the most likely differential diagnosis until that point. The biopsy confirmed the diagnosis of reactive arthritis in the setting of C. difficile colitis. The patient improved on treatment with naproxen and was referred to rheumatology where he was found to be HLA-B27 positive.

Septic arthritis post anterior cruciate ligament reconstruction due to Clostridioides difficile

Clostridioides difficile is an obligate anaerobe ubiquitous in the environment and is of particular interest in the healthcare setting as a cause of healthcare associated infection usually presenting with colitis. Extracolonic manifestations of C. difficile infection are less common with only rare reports of septic arthritis primarily in the setting of relative or overt immunocompromise. This report details the case of a 31-year-old immunocompetent male presenting with clinical features of septic arthritis, three weeks post right knee anterior cruciate ligament (ACL) reconstruction using a native hamstring tendon graft. C. difficile was isolated from two different samples of the synovial tissue from a subsequent arthroscopic washout and synovectomy. The ACL graft was retained. The isolate underwent whole genome sequencing and was found to be tcdA and tcdB gene deficient. Susceptibility testing showed susceptibility to benzylpenicillin and metronidazole. The patient received a two-week course of intravenous benzylpenicillin and four weeks of oral metronidazole. At one-year post cessation of antibiotics the patient has no clinical evidence of recurrence. This is the first known reported case of C. difficile septic arthritis in an immunocompetent patient. It demonstrates successful treatment of post-ACL septic arthritis with a graft retention strategy.

Native joint septic arthritis due to Clostridium tarantellae

Clostridium is a diverse genus including more than 200 species involved in varied clinical presentations in infectious diseases. Septic arthritis caused by Clostridium sp. are however uncommon. We report here the first septic arthritis due to Clostridium tarantellae, formerly called Eubacterium tarantellae, in a patient under anti-TNF therapy.

Hypertrophic osteoarthropathy mimicking a reactive arthritis: a case report and review of the literature

Background

Hypertrophic osteoarthropathy (HOA) is a syndrome characterized by abnormal proliferation of skin and periosteal tissues of the extremities. It can be a rare hereditary disease (pachydermoperiostosis) or can be secondary to various diseases, though mostly lung malignancies. Here, we report an unusual clinical presentation of HOA.

Case presentation

A 77-year-old man presented with fever, diarrhea, and an oligoarthritis involving the left knee and the ankles. Since left knee synovial fluid aspiration revealed an aseptic synovitis and Clostridium Difficile toxin was detectable in stool samples, a reactive arthritis secondary to a Clostridium Difficile induced colitis was initially suspected. However, the presence of a worsened digital clubbing and the lack of a good clinical response to steroid therapy led us to perform a radionuclide bone scanning, which revealed HOA. This turned out to be associated with a lepidic predominant lung adenocarcinoma, which was clinically and radiologically difficult to distinguish from a relapse of pneumonia.

Conclusion

Consistent with the literature, HOA tends to have a variable clinical presentation, mimicking that of various rheumatic diseases. This clinical case shows that HOA can present as a presumptive acute reactive arthritis, and it highlights the importance of patient’s follow-up in the differential diagnosis of inflammatory arthritis, especially when a worsened digital clubbing is present.

Clostridium difficile Colitis Leading to Reactive Arthritis: A Rare Complication Associated With a Common Disease

The relationship between reactive arthritis and enteric infections caused by Yersinia enterocolitica, Campylobacter jejuni, and Salmonella typhimurium is well documented. Clostridium difficile colitis is a less recognized cause of reactive arthritis. We present a case of a 58-year-old woman with Clostridium difficile colitis complicated by reactive arthritis. A 58-year-old woman with no significant past medical history presented to our hospital with complaints of nonbloody watery diarrhea, abdominal pain for the past 1 week, and right knee pain starting 1 day prior. The patient had recently used antibiotics for a respiratory tract infection. On examination, the patient had a swollen and erythematous right knee. While in the hospital the patient also developed a similarly painful and swollen left knee. The patient was found to be positive for C difficile toxin in stool. Synovial fluid analysis of both the knee joints revealed a sterile and inflammatory fluid, negative for crystals and showing no growth on gram stain. We diagnosed the patient with reactive arthritis secondary to C difficile colitis once all other causes of the bilateral knee joint symptoms were ruled out with appropriate laboratory and imaging studies. Treatment with oral vancomycin and an anti-inflammatory was initiated, and the patient had complete resolution of symptoms. This case illustrates the importance of recognizing C difficile colitis as a potential differential for reactive arthritis under the appropriate circumstances. The treatment of reactive arthritis is mainly supportive and treating the underlying cause, which happens to be C difficile in this case.

Bacteremia and Septic Arthritis due to a Nontoxigenic Strain of Clostridium difficile in a Patient With Sickle Cell Disease

A 22-year-old female with sickle cell disease presented with fevers, bilateral knee pain, and lethargy. Laboratory data revealed a leukocytosis and lactic acidosis. Blood and synovial fluid cultures grew a non-toxin-producing strain of Clostridium difficile. This case highlights the fact that nontoxigenic Clostridium difficile can cause significant disease.
