Relevance of vein wall thickness in Behcet's disease: A systematic review and meta-analysis.

OBJECTIVES: To perform a meta-analysis on articles evaluating the common femoral vein wall thickness (VWT) in Behcet's disease and its possible clinical, laboratory and treatment correlates (BD). METHODS: Systematic search of EMBASE and PubMed databases from inception to October 2023; we employed random effect meta-analyses for continuous outcomes. RESULTS: The meta-analysis included 9 case-control and 1 cohort study: the VWT was greater in BD (n = 650) than in controls (n = 396) (p < 0.0001) with wide heterogeneity (I2 = 94.4%); a sensitivity analysis that included mean age of BD participants, gender, disease duration and activity, C-reactive protein, smoking status, immune-suppressive and anti-inflammatory medication, revealed that the heterogeneity variance was partly explained by age (p < 0.0001), male gender (p = 0.03), disease duration (p < 0.0001) and smoking (p = 0.06). The VWT was greater in BD with thrombotic/vascular (n = 189) than in non-thrombotic/vascular BD (n = 140) (p = 0.006) with no heterogeneity. CONCLUSION: VWT is greater in BD than controls: age, male gender, disease duration and smoking relate to VWT that was greater in BD patients with a history of thrombotic/vascular disease. Prospective studies are required to assess whether VWT may be considered a vascular marker of disease activity.

Systemic Mastocytosis: A Mimicker of Reactive Arthritis.

Objectives: Illustration of a case of systemic mastocytosis mimicking reactive arthritis in the absence of an infectious etiology. Methods: Review of the patient's medical records. Results: We report a case of systemic mastocytosis relapse, presenting with pancytopenia accompanied by knee monoarthritis, cystitis, and bilateral conjunctivitis occurring simultaneously at the same time interval within 2-4 days, mimicking reactive arthritis in the absence of an infectious etiology. Conclusion: Our case demonstrated reactive arthritis features (triad of urethritis, conjunctivitis, and arthritis) without an infectious trigger but rather a relapse of mastocytosis. We should think outside the box when faced with such a clinical scenario in the absence of an infectious etiology. Paraneoplastic reactive arthritis is to be considered after excluding an underlying infection.

Subclinical atherosclerosis in Behcet's disease and its inverse relation to azathioprine use: an updated meta-analysis.

To evaluate the intima media thickness of carotid arteries (IMT) and its clinical, laboratory and treatment correlates in Behcet's disease (BD). Systematic search of EMBASE and PubMed databases from January 2016 to October 2022; we employed random effect meta-analyses for continuous outcomes and Peto's odds ratio for rare events. The meta-analysis included 36 case control studies: the IMT was greater in BD (n = 1103) than in controls (n = 832) (p < 0.0001) with wide heterogeneity (I2 = 86.9%); a sensitivity analysis that included mean age of BD participants, gender, disease duration and activity, atherogenic index of plasma, blood pressure, C-reactive protein, ethnicity, smoking status, anti-inflammatory and immune suppressive agents, revealed that male gender, mean age of participants and azathioprine use (the latter two in inverse fashion) partly explained the heterogeneity variance (p = 0.02, p = 0.005, and p = 0.01). The IMT was greater in vascular (n = 114) than in non-vascular BD (n = 214) (p = 0.006). BD patients (n = 782) had a greater pooled prevalence of carotid plaques than controls (n = 537) (13.1% vs. 2.97%, p < 0.0001). Subclinical carotid artery atherosclerosis represents a vascular feature of BD, independently of the traditional cardiovascular risk factors. The inverse correlations between IMT, age and azathioprine use suggest that thicker carotid arteries at disease onset eventually regress with immune suppressive treatment: this assumption needs verification on adequately designed clinical trials.

Subjective loss of clinical response to TNFi in axSpA relates to recurrence of MRI bone marrow oedema particularly with long-acting agents.

OBJECTIVES: Subjective loss of response immediately prior to routine TNFi therapy can occur in axial spondyloarthritis (axSpA). We investigated clinical outcomes in patients taking the first three licenced TNFis and correlated this with recurrence of MRI bone marrow oedema (MRI-BMO). METHODS: Proof-of-concept study including axSpA patients established on etanercept (ETA), adalimumab (ADA) or infliximab (IFX) reporting symptom deterioration prior to next dose. MRI/clinical data were collected prior to scheduled dose (v1), 4 days post-dose (v2) and at the time of patient-reported symptom return (v3). MRI spine/sacroiliac joints utilizing 3 T were scored using the semi-quantitative Leeds MRI scoring system. RESULTS: A total of 113 clinical assessments and MRIs were performed in 38 participants (ADA = 16, ETA = 12, IFX = 10), mean age 42.1 years ± 24.4(2SD, n = 38), 71.1% male (n = 27/38), 69.7% HLA-B27 positive (n = 23/33). At v1, all patients had high disease activity [ASDAS-CRP = 3 (2.7-3.7)] and 57.9% had MRI-BMO (number of MRI-BMO: ETA = 26, ADA = 59, IFX = 28). Improved clinical responses were seen at v2 [ASDAS-CRP -0.41(-0.81 - 0.30), P =0.018; BASDAI -0.58(-2.2 - 0.52), P =0.024]. Despite just a 4-day interval between v1 and v2, a numerical reduction in MRI-BMO lesions between v1/v2 was observed (ETA = -6, ADA = -10, IFX = -3). By v3, comparatively fewer new BMO lesions were detected in the ETA and ADA groups compared with IFX (ETA = -1, ADA = +3, IFX = +8), although the numbers were too small to enable testing for statistical significance. CONCLUSIONS: Short-lived fluctuations in MRI-BMO were commoner with longer-acting agents and corresponded with subjective loss of clinical response before next scheduled TNFi dose. Larger studies are needed to confirm the possible pathogenic implications of this phenomenon.

Ultrasound shows swollen joints are the better proxy for synovitis than tender joints in DMARD-naïve early psoriatic arthritis.

Objective: To evaluate the relationship between clinical examination/US synovitis in DMARD-naïve early PsA. Methods: Eligible patients underwent matched clinical/US 44-joint assessment for tender and/or swollen joints (TJ/SJ) and US synovitis [grey scale (GS) ≥ 2 or power Doppler (PD) ≥ 1]. Statistical agreement between TJ/SJ, GS ≥ 2 and PD ≥ 1 was calculated by prevalence-adjusted and bias-adjusted κ (PABAK). To derive probabilities of GS ≥ 2/PD ≥ 1, mixed-effects logistic regression-modelled odds of US synovitis in TJ/SJ were conducted. Results: In 155 patients, 5616 joints underwent clinical/US examination. Of these joints, 1039 of 5616 (18.5%) were tender, 550 of 5616 (9.8%) were swollen, 1144 of 5616 (20.4%) had GS ≥ 2, and 292 of 5616 (5.2%) had PD ≥ 1. GS ≥ 2 was most prevalent in concomitantly tender and swollen joints [205 of 462 (44%)], followed by swollen non-tender joints [32 of 88 (36.4%)], tender non-swollen joints [148 of 577 (25.7%)] and non-tender non-swollen joints (subclinical synovitis) [759 of 4489 (16.9%)]. Agreement between SJ/PD ≥ 1 was high at the individual joint level (82.6-96.3%, PABAK 0.65-0.93) and for total joints combined (89.9%, PABAK 0.80). SJ/GS ≥ 2 agreement was greater than between TJ/GS ≥ 2 [73.5-92.6% vs 51.0-87.4% (PABAK 0.47-0.85 vs PABAK 0.35-0.75), respectively]. Swelling was independently associated with higher odds of GS ≥ 2 [odds ratio (OR) (95% CI); 4.37 (2.62, 7.29); P < 0.001] but not tenderness [OR = 1.33 (0.87, 2.06); P = 0.192]. Swelling [OR = 8.78 (3.92, 19.66); P < 0.001] or tenderness [OR = 3.38 (1.53, 7.50); P = 0.003] was independently associated with higher odds of PD ≥ 1. Conclusion: Synovitis (GS ≥ 2 and/or PD ≥ 1) was more likely in swollen joints than in tender joints in DMARD-naïve, early PsA. Agreement indicated that swollen joints were the better proxy for synovitis, adding to greater understanding between clinical and US assessments.

Moraxella nonliquefaciens septic arthritis in a hematopoietic stem cell transplant patient a case report and review of the literature.

BACKGROUND: Septic arthritis is a common rheumatologic condition with myriad microbiological causative agents. Moraxella is one of the very rare causes of septic arthritis. We hereby present the third case of Moraxella nonliquefaciens septic arthritis and the first case in a hematopoietic stem cell transplant patient (HSCT) along with a brief review of the literature. METHODS: We used PubMed with google search engine to search the literature for reported cases of moraxella septic arthritis. RESULTS: Information on 19 other cases of moraxella infectious arthritis was found. M. catarrhalis was the most common species isolated. Only 2 reports on M. nonliquefaciens were found; the first one in a multiple myeloma patient and the second one in a diabetic patient on hemodialysis. Predisposing conditions included inflammatory arthritis, prosthetic joints, diabetes, Human Immunodeficiency Virus (HIV) infection, Hepatitis C, hemodialysis, esophageal cancer, valve replacements, alcoholism and Intravenous (IV) drug use. The age group of the reported cases ranged from 3 months to 78 years. CONCLUSION: Infectious arthritis with Moraxella spp. is a very rare entity which can occur in any age group and in the setting of various underlying medical conditions.

A review of current management of vasculo-Behcet's.

PURPOSE OF REVIEW: To give an overview of recently published articles about the management of vasculo-Behcet's with particular emphasis on anticoagulation. RECENT FINDINGS: Biologic agents are emerging as a potential therapeutic option in refractory vasculo-Behcet with a good safety profile. Evidence further shows that following nonpulmonary aneurysm repair, there is a reduced risk of recurrent aneurysmal formation at the operative site in patients treated with immunosuppressants in addition to their surgery, than those undergoing surgical intervention alone. SUMMARY: Behcet disease patients are at risk of developing multiple vascular complications including thrombosis and aneurysms. Treatment should focus on reducing inflammation; and the role of anticoagulation is still debatable.

The problem in differentiation between psoriatic-related polyenthesitis and fibromyalgia.

The recognition of the primacy of enthesitis in animal models of spondyloarthritis and the prevalence of clinically occult enthesopathy in psoriatic subjects and of persistent joint pain in PsA subjects who have ostensibly good reduction of joint swelling under biological therapy has highlighted the potential impact of polyenthesitis in psoriatic disease. In daily practice, the formal demonstration of enthesitis is challenging for the following reasons: the relatively avascular nature of enthesis, often leading to the absence of overt clinical inflammatory signs; the frequent lack of elevation of inflammatory markers; and finally, the limitations of current imaging techniques to provide supportive evidence for inflammation in these areas. Consequently, enthesitis may present as widespread pain indistinguishable from FM or may emerge as the dominant feature after successful biological therapy for suppression of synovitis. The unmet needs in the differentiation between FM and enthesitis in psoriatic disease patients are highlighted and critically evaluated in this article.
