Axial spondyloarthritis in patients with recurrent fever attacks: data from the AIDA network registry for undifferentiated autoInflammatory diseases (USAIDs).

Beckground: Despite the recent advances in the field of autoinflammatory diseases, most patients with recurrent fever episodes do not have any defined diagnosis. The present study aims at describing a cohort of patients suffering from apparently unexplained recurrent fever, in whom non-radiographic axial spondylarthritis (SpA) represented the unique diagnosis identified after a complete clinical and radiologic assessment. Materials and methods: Patients' data were obtained from the international registry on Undifferentiated Systemic AutoInflammatory Diseases (USAIDs) developed by the AutoInflammatory Disease Alliance (AIDA) network. Results: A total of 54 patients with recurrent fever episodes were also affected by non-radiographic axial SpA according to the international classification criteria. SpA was diagnosed after the start of fever episodes in all cases; the mean age at the diagnosis of axial SpA was 39.9 ± 14.8 years with a diagnostic delay of 9.3 years. The highest body temperature reached during flares was 42°C, with a mean temperature of 38.8 ± 1.1°C. The most frequent manifestations associated to fever were: arthralgia in 33 (61.1%) cases, myalgia in 24 (44.4%) cases, arthritis in 22 (40.7%) cases, headache in 15 (27.8%) cases, diarrhea in 14 (25.9%) cases, abdominal pain in 13 (24.1%) cases, and skin rash in 12 (22.1%) cases. Twenty-four (44.4%) patients have taken daily or on-demand non-steroidal anti-inflammatory drugs (NSAIDs) and 31 (57.4%) patients have been treated with daily or on demand oral glucocorticoids. Colchicine was used in 28 (51.8%) patients, while other conventional disease modifying anti-rheumatic drugs (cDMARDs) were employed in 28 (51.8%) patients. Forty (74.1%) patients underwent anti-tumor necrosis factor (TNF) agents and 11 (20.4%) were treated with interleukin (IL)-1 inhibitors. The response to TNF inhibitors on recurrent fever episodes appeared more effective than that observed with anti-IL-1 agents; colchicine and other cDMARDs were more useful when combined with biotechnological agents. Conclusion: Signs and symptoms referring to axial SpA should be inquired in patients with apparently unexplained recurrent fever episodes. The specific treatment for axial SpA may lead to a remarkable improvement in the severity and/or frequency of fever episodes in patients with unexplained fevers and concomitant axial SpA.

Validation of a disease-specific health-related quality of life measure in adult Portuguese patients with systemic lupus erythematosus: LupusQoL-PT.

INTRODUCTION: LupusQoL is a questionnaire specifically designed to assess health-related quality of life (HRQoL) in SLE patients. We report on the translation and cross-cultural adaptation of LupusQoL into European Portuguese. METHODS: Translation and cultural adaptation were performed according to standard protocol described by the original developers. LupusQoL-PT was administered to patients during a routine visit from an outpatient clinic at a university hospital in Portugal. Content structure was validated using factorial analysis. Cronbach's alpha coefficient was computed for internal consistency. Sociodemographic were questioned during the visit and clinical data were collected during the visit and from the clinical files. Pearson's correlation, T-test, Mann-Whitney and one-way ANOVA were applied to test internal and external validation. RESULTS: Seventy-nine SLE patients (78 woman: 1 man) were evaluated. Most had Low disease activity (mean SLEDAI-2k = 3.49; standard deviation 4.80), 19% had moderate to severe activity and 38% had damage accrual (mean SDI = 0.75; standard deviation 1.05). Cronbach's alpha coefficient was at least 0.812, confirming good internal consistency. Correlation coefficient and test-retest correlation between the eight domains of LupusQoL-PT were strong in almost every domain (p < 0.01). External convergent analysis showed strong correlation between LupusQoL-PT and Medical Outcome Study Short Form 36-item version 2 and visual analogic scale. Current disease activity was negative correlated with "Body Image" domain. There was no correlation between other LupusQoL-PT domains and SLEDAI-2k on divergent validity. Patients with previous neuropsychiatric and DMARDs treatment had lower HRQoL in emotional domains, while patients with renal damage accrual had HRQoL impact in both physical and emotional domains. Portuguese SLE patients had lower HRQoL than French and Italian validation cohorts' patients, and higher than Spanish cohorts. CONCLUSION: LupusQoL-PT has shown adequate metric properties and should be considered an appropriate tool to evaluate HRQoL in Portuguese SLE patients.

The Role of a Medical Intermediate Care Unit in the Management of Budd-Chiari Syndrome: Case Series.

Budd-Chiari syndrome (BCS) has a wide spectrum of presentations, from an asymptomatic status to acute liver failure (ALF). The therapeutic approach depends on disease severity and related etiology with patients with severe forms of presentation classically managed in intensive care units (ICUs). Here, we report a series of five BCS patients managed in a medical intermediate care unit (IntCU), with three of them presenting with acute liver injury. Progression to ALF was seen in three patients, two of whom died, with one being successfully submitted to liver transplantation. IntCUs allow a 24-h patient surveillance and a prompt management of BCS, with less economic impact when compared to ICUs. Mortality was related to the presence of associated comorbidities that limited therapeutic approach.

Brugada Pattern: Unraveling Possible Cardiac Manifestation of SARS-CoV-2 Infection.

We report the case of a 41-year-old patient with no family history of sudden cardiac death. The patient presented with high fever and vomiting and was diagnosed with acute pyelonephritis. Screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was positive. An electrocardiogram (ECG) performed during a fever episode revealed a Brugada pattern. Fever can be a trigger for induction of the electrocardiographic Brugada pattern but it is still unknown if the cardiac involvement by coronavirus disease 2019 (COVID-19) can interfere with myocardial ion channels.

An Overview of Bimekizumab for the Treatment of Psoriatic Arthritis: The Evidence so Far.

Psoriatic arthritis is a complex and heterogeneous disease with potential significant disability and impaired quality of life. Although in the last decades new treatment options have led to a better management of this disease, there are still significant unmet therapeutic needs. Dual inhibitor antibodies target two different cytokines simultaneously, potentially offering a better disease control. In psoriatic arthritis, there is evidence for a pathogenic role not only of IL-17A but also the structurally homologous IL-17F. It is postulated that differential expression of both in several targets of PsA could account for disparities in clinical response to IL-17A inhibition alone (such as with secukinumab or ixekizumab). Here we review the evidence so far for the use in psoriatic arthritis of bimekizumab, the first humanized monoclonal IgG1 antibody that selectively neutralizes both IL-17A and IL-17F. A Phase 2b trial reports better outcomes over both placebo and IL-17A inhibition alone. Very recently encouraging results from open-label extensions with regards to both safety and maintenance of response were presented. Phase III trials are ongoing with the first results awaited in 2021.

Outcomes of membranous and proliferative lupus nephritis - analysis of a single-centre cohort with more than 30 years of follow-up.

OBJECTIVES: To compare membranous lupus nephritis (MLN) and proliferative lupus nephritis (PLN) with respect to survival, demographic, clinical and laboratory characteristics; and to investigate predictors of renal and patient survival. METHODS: Single-centre retrospective observational study. Patients with biopsy-proven PLN, MLN and mixed lupus nephritis were included. Groups were compared using appropriate statistical tests and survival was analysed through the Kaplan-Meier method. Cox regression analysis was performed to investigate predictors of renal and patient survival. RESULTS: A total of 187 patients with biopsy-proven lupus nephritis (135 with PLN, 38 with MLN and 14 with mixed LN) were followed for up to 42 years (median 12 years). There was a higher proportion of MLN amongst Afro-Caribbeans than amongst Caucasians (31% vs 15%, P = 0.010). Patients with MLN had significantly lower anti-dsDNA antibodies (P = 0.001) and higher C3 levels (P = 0.018) at diagnosis. Cumulative renal survival rates at 5, 10, 15 and 20 years were 91, 81, 75 and 66% for PLN and 100, 97, 92 and 84% for MLN, respectively (P = 0.028). Cumulative patient survival at 5, 10, 15 and 20 years was 94, 86, 80 and 76%, with no difference between PLN and MLN. Urinary protein-creatinine ratio above 42 mg/mmol and eGFR below 76 ml/min/1.73 m2, one year after the diagnosis of LN, were the strongest predictors of progression to end-stage renal disease. eGFR below 77 ml/min/1.73 m2, at one year, development of end-stage renal disease and Afro-Caribbean ethnicity were associated with higher mortality. CONCLUSION: Patients with MLN and PLN differ significantly regarding serological profiles and renal survival, suggesting different pathogenesis. Renal function at year one predicts renal and patient survival.
