Memory B cell subsets and plasmablasts are lower in early than in long-standing Rheumatoid Arthritis

Alterations of B cell subset distribution have been described in the peripheral blood (PB) of rheumatoid arthritis (RA) patients, but no data are available on differences between the onset and the established phases of the disease. The purpose of the study was to clarify whether a peculiar distribution of B cell subsets characterizes RA onset, thus leading to a more favorable clinical response to treatment, and to evaluate the possible association of a particular B cell subpopulation with response to therapy

Rheumatoid arthritis and Alzheimer's disease: genetic and epigenetic links in inflammatory regulation

Controversial data are available about the relationship between Alzheimer's disease (AD) and rheumatoid arthritis (RA). An inverse relationship between AD and RA, due to different factors, was previously described. Similarly to RA, AD pathogenesis is multifactorial and different findings support the inflammatory pathogenetic hypothesis. Several inflammatory mediators are involved in the disease onset and progression regulated by genetic and epigenetic mechanisms. Among them, inteleukin-6 (IL-6) and interleukin-1 (IL-1) as pro-inflammatory soluble factors produced by monocytes-macrophages and tumor necrosis factor alpha (TNF-\u3b1) produced by activated macrophages and mononuclear cells represent key molecules in the induction and maintenance of chronic inflammation in RA. In particular a link with the T allele of the SNP 3953 T/C in the IL-1 gene and an overexpression of miR-146a appears to be common to both RA and AD. In this review we will discuss the genetic and epigenetic regulation of the inflammatory cascade in RA and AD to find out the possible links between RA and AD onset

The prognostic significance of the Birmingham Vasculitis Activity Score (BVAS) with systemic vasculitis patients transferred to the intensive care unit (ICU)

Systemic vasculitides represent a heterogeneous group of diseases that share clinical features including respiratory distress, renal dysfunction, and neurologic disorders. These diseases may often cause life-threatening complications requiring admission to an intensive care unit (ICU). The aim of the study was to evaluate the validity and responsiveness of Birmingham Vasculitis Activity Score (BVAS) score to predict survival in patients with systemic vasculitides admitted to ICU. A retrospective study was carried out from 2004 to 2014 in 18 patients with systemic vasculitis admitted to 2 different Rheumatology divisions and transferred to ICU due to clinical worsening, with a length of stay beyond 24hours. We found that ICU mortality was significantly associated with higher BVAS scores performed in the ward (P=0.01) and at the admission in ICU (P= 0.01), regardless of the value of Acute Physiology And Chronic Health Evaluation (APACHE II) scores (P=0.50). We used receiveroperator characteristic (ROC) curve analysis to evaluate the possible cutoff value for the BVAS in the ward and in ICU and we found that a BVAS>8 in the ward and that a BVAS>10 in ICU might be a useful tool to predict in-ICU mortality. BVAS appears to be an excellent tool for assessing ICU mortality risk of systemic vasculitides patients admitted to specialty departments. Our experience has shown that performing the assessment at admission to the ward is more important than determining the evaluation before the clinical aggravation causing the transfer to ICU

An autosomal recessive DNASE1L3-related autoimmune disease with unusual clinical presentation mimicking systemic lupus erythematosus

We describe the third family in the world, after Arabian and Turkish ones, displaying an autosomal recessive autoimmune disease (AID), mimicking systemic lupus erythematosus (SLE), with unusual manifestations due to a homozygous frame-shift variant in DNASE1L3. SLE is a complex AID characterized by multiple organ involvement. Genetic risk variants identified account for only 15% of SLE heritability. Rare Mendelian forms have been reported, including DNASE1L3-related SLE. Through specific genetic tests we identified a homozygous 2 bp-deletion c.289_290delAC (NM_004944.2) in DNASE1L3, predicting frameshift and premature truncation (p.Thr97Ilefs*2). The same mutation was previously reported in three sisters, born from consanguineous parents and affected with hypocomplementemic urticarial vasculitis syndrome (HUVS). As approximately 50% of individuals affected with HUVS develop SLE, it is still unclear whether it is a SLE sub-phenotype or a separate condition. Lupus (2016) 0, 1\u20135

Stress Echocardiography in Italian Echocardiographic Laboratories: A Survey of the Italian Society of Echocardiography and Cardiovascular Imaging

Background: The Italian Society of Echography and Cardiovascular Imaging (SIECVI) conducted a national survey to understand the volumes of activity, modalities and stressors used during stress echocardiography (SE) in Italy. Methods: We analyzed echocardiography laboratory activities over a month (November 2022). Data were retrieved through an electronic survey based on a structured questionnaire, uploaded on the SIECVI website. Results: Data were obtained from 228 echocardiographic laboratories, and SE examinations were performed in 179 centers (80.6%): 87 centers (47.5%) were in the northern regions of Italy, 33 centers (18.4%) were in the central regions, and 61 (34.1%) in the southern regions. We annotated a total of 4057 SE. We divided the SE centers into three groups, according to the numbers of SE performed: <10 SE (low-volume activity, 40 centers), between 10 and 39 SE (moderate volume activity, 102 centers) and >= 40 SE (high volume activity, 37 centers). Dipyridamole was used in 139 centers (77.6%); exercise in 120 centers (67.0%); dobutamine in 153 centers (85.4%); pacing in 37 centers (21.1%); and adenosine in 7 centers (4.0%). We found a significant difference between the stressors used and volume of activity of the centers, with a progressive increase in the prevalence of number of stressors from low to high volume activity (P = 0.033). The traditional evaluation of regional wall motion of the left ventricle was performed in all centers, with combined assessment of coronary flow velocity reserve (CFVR) in 90 centers (50.3%): there was a significant difference in the centers with different volume of SE activity: the incidence of analysis of CFVR was significantly higher in high volume centers compared to low - moderate - volume (32.5%, 41.0% and 73.0%, respectively, P < 0.001). The lung ultrasound (LUS) was assessed in 67 centers (37.4%). Furthermore for LUS, we found a significant difference in the centers with different volume of SE activity: significantly higher in high volume centers compared to low - moderate - volume (25.0%, 35.3% and 56.8%, respectively, P < 0.001). Conclusions: This nationwide survey demonstrated that SE was significantly widespread and practiced throughout Italy. In addition to the traditional indication to coronary artery disease based on regional wall motion analysis, other indications are emerging with an increase in the use of LUS and CFVR, especially in high-volume centers
