Abstract
OBJECTIVE To explore the potential associations between high-density lipoprotein (HDL) levels and inflammasome components in the context of systemic lupus erythematosus (SLE). METHODS A cross-sectional study was conducted. A group of 50 patients with SLE and 50 healthy controls matched by sex and similar age ranges were enrolled. Serum HDL cholesterol (HDL-C) and C reactive protein (CRP) levels were quantified. Serum cytokine levels, including IL-1β and IL-6, were determined by ELISA. The gene expression of inflammasome-related genes in peripheral blood mononuclear cells was measured by quantitative real-time PCR. RESULTS HDL-C levels were lower in the patients with SLE (p<0.05), and on segregation according to disease activity, those with active SLE had the lowest HDL-C levels. Patients with SLE presented higher concentrations of the serum inflammatory cytokines IL-1β and IL-6 (p<0.0001) but similar levels of CRP to those in controls. A similar scenario was observed for the gene expression of inflammasome components, where all the evaluated markers were significantly upregulated in the SLE population. These results revealed significant negative correlations between HDL levels and disease activity, serum IL-6 and IL-1β levels and the mRNA expression of NLRP3, IL-1β and IL-18. In addition, significant positive correlations were found between disease activity and serum IL-1β and between disease activity and the mRNA expression of IL-18, and interestingly, significant positive correlations were also observed between active SLE and serum IL-1β and the mRNA expression of NLRP3. CONCLUSION Our results suggest that HDL is essential for SLE beyond atherosclerosis and is related to inflammation regulation, possibly mediated by inflammasome immunomodulation.

Abstract
OBJECTIVES To describe the care provided by Brazilian nurses to patients with Juvenile Systemic Lupus Erythematosus (JSLE) using a self-administered questionnaire and to evaluate the possible association of demographic data and knowledge of the disease with availability of tools for diagnosis and treatment in Brazilian pediatric services. METHOD This is a cross-sectional observational descriptive study that analyzed the care provided by Brazilian nurses to patients with JSLE based on the answers to a self-administered questionnaire. Questions included demographics of professionals, nursing consultation, usage of tools to assess disease activity, diagnostic criteria, general care, available practices, transition program, and practices needed for better care. RESULTS A total of 111/373 (29.4%) questionnaires were completed, most professionals were female (90.1%). Hospitalization (45.9%) and poor medication adherence (27.9%) were the most reported problems, and lack of knowledge about the institutional transition process to adult care was mentioned by half of the professionals (50.5%). Comparisons of professionals on expected care of patients regarding the type of service, hospitalized patient care, and care provided to patients with JSLE did not reveal statistically significant differences (p > 0.05). Nurses who care for patients with JSLE are more likely to work in a public setting (14.5% vs. 36.8%, p = 0.048) and less likely to verify vaccination records (0.12.9% vs. 36.8%, p = 0.038). Nurses who worked in the inpatient setting with patients with JSLE were less likely to address pain concerns (11.7% vs. 61.6%, p < 0.0001) compared to nurses who didn't work with JSLE patients. However, they were more likely to discuss sunscreen use (54.9% vs. 25%, p < 0.05) and be part of a multi-disciplinary team (84.3 vs. 50%, p < 0.0001). CONCLUSIONS This study demonstrates that the care provided by nurses to patients with JSLE does not consider all the resources available to assess the disease and occurs differently in the inpatient versus outpatient settings. Future research should address this gap in care. Lack of JSLE awareness was commonly reported among professionals, confirming the need for greater knowledge about JSLE, its treatment, and ways to improve adherence.

Abstract
BACKGROUND AND OBJECTIVE to analyse the association between interferon-1α (INF1α), interleukin-10 (IL-10) and BLyS concentrations and clinical activity in systemic lupus erythematosus (SLE). PATIENTS AND METHODS A cross-sectional, observational study of 142 SLE patients and 34 healthy controls was performed, through a complete blood and urine test and review of their medical history. Serum concentration of INF1α, IL-10 and BLyS was determined by colorimetric methods. A biostatistical analysis was performed with R (3.3.2.). RESULTS 69% of our SLE patients showed at least one cytokine increased. INF1α, IL-10 and BLyS are higher in SLE patients than in healthy controls (P<.001, P=.005 and P=.043, respectively), being INF1α the most frequent. Patients were categorised according to low or high concentrations of the three cytokines. We found a significant association between increased IL-10/INF1α concentrations and a higher clinical activity measured by SELENA-SLEDAI (P<.0001) and, to a lesser extent, an association with increased INF1α/IL-10/BLyS concentrations. Elevated levels of IL-10/INF1α and INF1α/IL-10/BLyS related to increased C3-C4 consumption (P<.001 and P=.001 respectively) and anti-dsDNA titres (P=.001 and P=.002 respectively). Elevated INF1α/BLyS related to higher anti-dsDNA titres (P=.004) and ENA positivity (P<.001). Increased levels of INF1α/IL-10/BLyS related to positivity of ANAs (P<.001) and APL (P=.004). CONCLUSIONS INF1α, IL-10 and BLyS are higher in SLE patients than in healthy controls. Increased IL-10 levels, regardless of whether or not there were also increased levels of BLyS and/or INF1α, was the cytokine that best fit with clinical activity in SLE measured with classic methods.

Abstract
Introduction Systemic lupus erythematosus is an autoimmune disease with multi-organ involvement. Complications, such as invasive fungal infections usually occur in patients with a greater severity of the disease. Objective The objective of this study was to determine the prevalence and risk variables associated with invasive fungal infections in a Colombian systemic lupus erythematosus population. Materials and methods A cross-sectional, retrospective study that evaluated patients with systemic lupus erythematosus for six years. The primary outcome was invasive fungal infection. Descriptive, group comparison and bivariate analysis was performed using Stata 12.0 software. Results Two hundred patients were included in this study; 84.5% of the patients were women and the median age was 36 years; 68% of the subjects had haematological complications; 53.3% had nephropathy; 45% had pneumopathy and 28% had pericardial impairment; 7.5% of patients had invasive fungal infections and the most frequently isolated fungus was Candida albicans. Pericardial disease, cyclophosphamide use, high disease activity, elevated ESR, C3 hypocomplementemia, anaemia and lymphopenia had a significant association with invasive fungal infection ( P < 0.05). Conclusions We describe for the first time the prevalence of invasive fungal infection in a Colombian population with systemic lupus erythematosus, which was higher than that reported in other latitudes. In this population the increase in disease activity, the presence of pericardial impairment and laboratory alterations (anaemia, lymphopenia, increased ESR and C3 hypocomplementemia) are associated with a greater possibility of invasive fungal infections. Regarding the use of drugs, unlike other studies, in the Colombian population an association was found only with the previous administration of cyclophosphamide. In addition, patients with invasive fungal infections and systemic lupus erythematosus had a higher prevalence of mortality and hospital readmission compared with patients with systemic lupus erythematosus without invasive fungal infection.

Abstract
Systemic lupus erythematosus (SLE) is a complex rheumatic multisystemic disease of autoimmune origin with significant potential morbidity and mortality. It is one of the most common autoimmune diseases with an estimated prevalence of 20-150 cases per 100,000 inhabitants. The clinical spectrum of SLE is wide and variable both in clinical manifestations and severity. This prompted the Spanish Ministry of Health, Social Services and Equality to promote and fund the development of a clinical practice guideline (CPG) for the clinical care of SLE patients within the Programme of CPG in the National Health System which coordinates GuiaSalud. This CPG is is intended as the reference tool in the Spanish National Health System in order to support the comprehensive clinical management of people with SLE by all health professionals involved, regardless of specialty and level of care, helping to standardize and improve the quality of clinical decisions in our context in order to improve the health outcomes of the people affected. The purpose of this document is to present and discuss the rationale of the recommendations on the general management of SLE, specifically, clinical follow-up, general therapeutic approach, healthy lifestyles, photoprotection, and training programmes for patients. These recommendations are based on the best available scientific evidence, on discussion and the consensus of expert groups.
