Diagnostic Algorithm for Joint Pain in Patients with Inflammatory Bowel Disorders

Aim. An algorithm development for joint pain differential diagnosis in patients with inflammatory bowel disorders (IBD) and its validation in clinical practice.Materials and methods. A total of 349 IBD patients hospitalised for gastroenterological complaints at the Chelyabinsk Regional Clinical Hospital during 2017–2020 have been examined.Results. Upon survey, 97 (27.8%) IBD patients complained of joint pain. Ulcerative colitis (UC) predominated (79 patients; 81.4%), Crohn’s disease (CD) had a 18.6% incidence. In survey, 27% UC and 32.1% CD patients reported joint pain (p = 0.26). Among IBD patients, 52.6% had mechanical, and 47.4% — inflammatory pain. The inflammatory back pain (IBP) rate in survey cohort was 23.7%. Use of a diagnostic algorithm allowed concomitant rheumatic disease detection in 7 (7.2%) patients from the IBD–joint pain cohort: 2 patients were diagnosed with psoriatic spondyloarthritis, 2 — rheumatoid arthritis, 1 — gout and 2 — with ankylosing spondylitis. IBD-associated arthritis was diagnosed in 41 (42.3%) cases, osteoarthritis — in 38 (39.2%) IBD patients with joint pain, arthralgia with no objective inflammation, impaired joint function or lesions in X-ray and/or ultrasound — in 13 (13.4%) patients.Conclusion. Joint pain complaints are common in IBD patients and require a multispecialty rheumatologists-involving approach to proceed with differential diagnosis and opting for treatment tactics. A clinically verified algorithm coupled with laboratory tests and instrumental imaging facilitates diagnosis and optimal therapy selection in IBD patients with complaints of joint pain.

Changes in ankylosing spondylitis incidence, prevalence and time to diagnosis over two decades

ObjectivesTo assess changes in ankylosing spondylitis (AS) incidence, prevalence and time to diagnosis, between 1998 and 2017.MethodsUsing UK GP data from the Clinical Practice Research Datalink, we identified patients diagnosed with AS between 1998 and 2017. We estimated the annual AS incidence, prevalence and length of time from first recorded symptom of back pain to rheumatology referral and diagnosis.ResultsWe identified 12 333 patients with AS. The incidence declined from 0.72 (±0.14) per 10 000 patient-years in 1998 to 0.39 (±0.06) in 2007, with this decline significant only in men, then incidence rose to 0.57 (±0.11) in 2017. By contrast, prevalence increased between 1998 and 2017 (from 0.13%±0.006 to 0.18%±0.006), rising steeply among women (from 0.06%±0.05 to 0.10%±0.06) and patients aged ≥60 (from 0.14%±0.01 to 0.26%±0.01). The overall median time from first symptom to rheumatology referral was 4.87 years (IQR=1.42–10.23). The median time from first symptom to diagnosis rose between 1998 and 2017 (from 3.62 years (IQR=1.14–7.07) to 8.31 (IQR=3.77–15.89)) and was longer in women (6.71 (IQR=2.30–12.36)) than men (5.65 (IQR=1.66–11.20)).ConclusionAS incidence declined significantly between 1998 and 2007, with an increase between 2007 and 2017 that may be explained by an improvement in the recognition of AS or confidence in diagnosing AS over time, stemming from increased awareness of inflammatory back pain and the importance of early treatment. The rising AS prevalence may indicate improved patient survival. The persisting delay in rheumatology referral and diagnosis remains of concern, particularly in women.

Ankylosing spondylitis: diagnostic challenges and efficacy of upadacitinib

Ankylosing spondilitis (AS) is a relatively common disease mainly affecting young males and presenting with chronic inflammation of the spine and the sacroiliac joints. AS is one of the forms of axial spondyloarthritis (SpA). Diagnosis of AS is usually delayed on average by 8-10 years from the first symptoms. SpA should be considered both in males and females who present with chronic low back pain starting before the age of 45 years and at least one additional factor (inflammatory back pain, HLA-B27, sacroileitis, peripheral arthritis, enthesitis, dactylitis, psoriasis, uveitis, inflammatory bowel disease, family history for SpA, elevated ESR and/or C-reactive protein, and good response to NSAIDs). Such patients should be referred to rheumatologist. MRI improves early diagnosis of AS since it detects inflammatory changes, which precede structural damage of the sacroiliac joints (nonradiographic SpA). Physical exercises and NSAIDs are the first-line treatment for AS, whereas TNF and interleukin-17 inhibitors are widely used as a second-line therapy. Upadacitinib is the first JAK-inhibitor that was approved for the treatment of active AS in adult patients who have responded inadequately to conventional therapy. The authors discuss clinical cases demonstrating efficacy of upadacinitib in patients with AS.

Rheumatologic manifestations in a cohort of patients with Vogt–Koyanagi–Harada disease

ABSTRACT Objectives Vogt–Koyanagi–Harada Disease (VKHD) is a systemic autoimmune disorder characterized by granulomatous panuveitis. Inflammatory rheumatic diseases (IRDs) are among the differential diagnosis of VKHD. However, current knowledge on the rheumatological aspects of VKHD is still limited. We aimed to investigate the prevalence of rheumatic conditions in VKHD patients. Methods VKHD patients were included in the study and they were reviewed in terms of the presence of any rheumatological manifestations. Results There were 18 patients with a female preponderance (83.3%, female). Inflammatory type of peripheral joint pain (11%) and sicca symptoms (33%) were the most common rheumatological findings. The frequency of spondyloarthritis-related features such as inflammatory back pain and HLA-B27 rate was not increased. None of the patients had radiographic sacroiliitis. Anti-nuclear antibody was positive in high titres nearly in 30% of the patients and three patients had antibodies against extractable nuclear antigens. Nailfold capillaroscopy was abnormal in about one-third of the patients. Pathergy test was negative in all cohorts. While angiotensin-converting enzyme was elevated in nearly 20% of the patients, there were no abnormalities on chest X-rays. Conclusion VKHD shares some features with IRDs. The common features were mostly suggestive of connective tissue disease rather than SpA or rheumatoid arthritis.

Enthesitis Related Arthritis: A Single Center Experience

Objective: Enthesitis-related arthritis is a subtype of juvenile idiopathic arthritis category, characterized by enthesitis, arthritis, and the risk of axial involvement. We aimed to summarize the demographics, clinical, and laboratory findings of enthesitis-related arthritis patients and to identify the distinguishing features of enthesitis-related arthritis patients with HLA B27 positive compared to the patients who were HLA B27 negative. Materials and Methods: This retrospective study included patients with Enthesitis-related arthritis who followed up between 2015 and 2018. Demographical, clinical, and laboratory data were retrospectively reviewed from the patient files and computerized medical charts. Results: A total of 72 patients diagnosed with enthesitis-related arthritis were included in the study. The male/female ratio was 2.1/1. Fifty-three (73%) of them presented with peripheral arthritis. The most commonly affected joint was knee (81.1%), followed by the ankle (43%), hips (32%), and wrist (5%). HLA B27 was positive in 36 (50%) patients. During follow-up, the number of patients who developed enthesitis-related arthritis -associated uveitis was 8 (11.1%). During follow-up, 56 patients with inflammatory back pain and/or sacroiliac tenderness underwent spinal MRI. Ten (17.8%) patients had only thoracal and/or lumbar involvement, 18 (32%) had only sacroiliitis, and 9 (16%) patients had both of them on spinal MRI. In comparison with HLA-B27-negative children, HLA-B27-positive patients were more likely to have enthesitis (16 (44.4%) vs 8 (22.2%), p=0.046), MRI proven sacroiliitis (19 (52.7%) vs 8 (22.2%), p=0.031), MRI proven spinal involvement (13 (36.1%) vs 6 (16.6%), p=0.031), and uveitis (8 (100%) vs 0(0%), p=0.014). During follow up, 65/72 (90.2 %) of them needed disease-modifying antirheumatic drugs (DMARD), and 51/72 (70.8%) needed anti-tumor necrosis factor-α (TNF-α) therapy. Conclusion: We found that patients who were HLA-B27- positive had significantly more enthesitis, MRI-proven sacroiliitis, MRI-proven spinal involvement, and acute anterior uveitis, in comparison to patients who were HLA B27 negative. It is crucial to carefully assess those patients with concern for enthesitis-related arthritis to determine the expected prognosis and make therapeutic decisions appropriately.

A case of effective use of interleukin 6 inhibitors in patients with ankylosing spondylitis with secondary amyloidosis

Ineffectiveness of interleukin 6 inhibitors (iIL6), tocilizumab (TCZ) and sarilimumab in ankylosing spondylitis (AS) was shown in randomized clinical trials. However, there is ample evidence that IL6 is actively involved in the pathogenesis of this disease. In addition, the efficacy of iIL6 in patients with secondary AA-amyloidosis was established.Objective: to analyze the results of TCZ administration in AS, complicated by secondary AA-amyloidosis.Patients and methods. The analysis included 6 patients with AS with secondary AA-amyloidosis. All patients were HLA-B27 positive male. The average age of patients was 44±9.2 years, the average age of the disease onset was 16.3±7.9 years, the average duration of AS was 26.0±7.5 years. All 6 patients had pathomorphologic confirmed secondary AA-amyloidosis: all had kidney affection, 5 patients also had gastrointestinal tract affection and 2 had heart affection. As a first biological drug TCZ was prescribed in 2 patients, and 4 patients had previously received one or more inhibitors of tumor necrosis factor α. The average duration of TCZ treatment was 27.6 [3.0; 36.0] months.Results and discussion. During TCZ therapy, the level of CRP (M±σ) significantly decreased: from 81.1±74.5 to 1.2±0.8 mg/L (p<0.05), as well as daily proteinuria (Me [25th ; 75th percentile]): from 1.8 [1.0; 2.1] to 0.2 [0.1; 0.3] g/day (p<0.05) and AS activity indices – BASDAI (M±σ): from 6.2±1.6 to 3.3±0.9 (p<0.05 ); ASDAS-CRP (M±σ) from 4.6±1.1 to 2.04±0.7 (p<0.05). Positive dynamics was also noted in relation to a decrease in the number of patients with inflammatory back pain, arthritis and coxitis. A case of clinical and laboratory remission of AS on TCZ treatment is described. Conclusion. The presented data show that in certain clinical situations iIL6 can be highly effective in AS.

Post-COVID-19 Arthritis and Sacroiliitis: Natural History with Longitudinal Magnetic Resonance Imaging Study in Two Cases and Review of the Literature

Severe acute respiratory coronavirus-2 syndrome (SARS-CoV-2) is a well-known pandemic infectious disease caused by an RNA virus belonging to the coronaviridae family. The most important involvement during the acute phase of infection concerns the respiratory tract and may be fatal. However, COVID-19 may become a systemic disease with a wide spectrum of manifestations. Herein, we report the natural history of sacroiliac inflammatory involvement in two females who developed COVID-19 infection with mild flu-like symptoms. After the infection they reported inflammatory back pain, with magnetic resonance imaging (MRI) studies showing typical aspects of sacroiliitis. Symptoms improved with NSAIDs therapy over the following months while MRI remained positive. A literature review was performed on this emerging topic. To our knowledge, this is the first MRI longitudinal study of post-COVID-19 sacroiliitis with almost one year of follow-up. Predisposing factors for the development of articular involvement are unclear but a long-lasting persistence of the virus, demonstrated by nasopharyngeal swab, may enhance the probability of altering the immune system in a favourable background.
