Abstract
OBJECTIVES to evaluate the main factors associated with mortality and determine the life expectancy of SLE patients between 2000 and 2019 years in Brazil. METHODS death data related to SLE available in the Brazilian Unified Health System (SUS) (DATASUS) were evaluated in all Brazilian states. Three groups of death causes potentially associated from SLE were evaluated: cardiovascular and kidney diseases and infections. RESULTS The main causes of death associated with SLE were infection and kidney disease. Most SLE patients died between 19 and 50 years of age. Deaths associated with kidney disease were proportionally higher than in the general population with progressive decrease during the period. Instead, there have been an increase in the proportion of deaths due to infections both in SLE and in the general population. CONCLUSIONS SLE patients presented higher mortality compared to the general population matched for sex and age and the main causes associated with death were infection and kidney disease. Public health policies that promote early diagnosis, treatment and prevention of damage are necessary to reduce morbidity and mortality in SLE patients.

Abstract
Systemic lupus erythematosus (SLE) is a disease that affects the immune system, and it can lead to increased morbidity and mortality. The primary causes of mortality for individuals with SLE are disease activity, infections, drug toxicity, and other health conditions. The aim of this study is to estimate the mortality rate of patients with SLE who are hospitalized, describe the causes of death, and identify factors associated with mortality. The study was conducted at a referral hospital from 2009 to 2021, utilizing a nested case-control design. The records of patients with SLE who were hospitalized in the Department of Rheumatology were reviewed. Cases were identified as individuals who died during their hospitalization, while controls were those who were discharged alive during the same period. Elective hospitalizations were not included in the study. The primary causes of death were recorded, and demographic, clinical, laboratory, and immunological variables were analyzed as potential risk factors associated with in-hospital mortality. The study included 105 patients who died while hospitalized and 336 who were discharged alive. The estimated mortality rate was 10.93 deaths per 1000 hospital admissions per year. The leading causes of death were SLE activity (20%), infections (34.2%), or a combination of both (24.8%). Risk factors associated with in-hospital mortality were any infection (OR 2.5, CI 95% 1.2-5.2), nosocomial infections (OR 5.0, CI 95% 1.8-13.7), SLEDAI-2K > 2 (OR 2.0, CI 95% 1.02-3.8), lymphopenia (OR 2.1, CI 95% 1.01-4.6), anemia (OR 2.9, CI 95% 1.4-5.7), and thrombocytopenia (OR 3.3, CI 95% 1.7-6.4). Disease activity and infections, particularly nosocomial infections, are significant causes of mortality in hospitalized patients with SLE. Furthermore, hematological manifestations play a significant role in in-hospital mortality for these patients.

Comparison of Urinary Protein/Creatinine Ratio as an Alternative to 24-h Proteinuria in Lupus Nephritis: TUNARI Study. Nephron Clin Pract 2023; 147:643-649. [PMID: 37356429 DOI: 10.1159/000531333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 04/13/2023] [Indexed: 06/27/2023] Open
Abstract
BACKGROUND Lupus nephritis (LN) occurs in approximately 50% of people with systemic lupus erythematosus (SLE). The 24-h proteinuria (gold standard) is measured among other tests for the control and monitoring of LN activity. This study investigates the use of the protein/creatinine ratio (PCR) as an alternative for the detection of proteinuria and its accuracy compared to the gold standard in a predominantly non-white population. METHODS This was a prospective study conducted in Salvador, Brazil, between December 2021 and May 2022. We invited adult patients diagnosed with SLE and LN, regardless of their disease activity. The estimation of the PCR and 24-h proteinuria was performed using conventional methods. The analysis used was Spearman's r correlation coefficient (rs), coefficient of determination (r2), and concordance by the Bland-Altman method. A specific sensitivity was measured by the ROC curve with its respective cut-off by the Youden Index. RESULTS We compared 112 samples of 75 patients with LN, with a mean age of 34.5 ± 11.8 years. Of these patients, 85% were women, 87.9% were non-white. A high degree of correlation was observed between PCR with 24-h proteinuria (rs = 0.77 and r2 = 0.59). The ROC analysis shows an area under the curve of 0.92 and the cut-off point calculated by the Youden Index was 0.78 with a sensitivity of 90.0% and specificity of 82%. However, the Bland-Altman graph indicated decreasing concordance as the degree of proteinuria increased, despite showing concordance at high levels of proteinuria. CONCLUSION The PCR shows high sensitivity to follow-up patients with LN when compared with 24-h proteinuria. Our findings suggest that PCR is a useful parameter for the evaluating and monitoring patients in complete remission. However, in cases of partial remission, the utility of PCR is limited.

Abstract
INTRODUCTION Systemic lupus erythematosus (SLE) is a chronic autoimmune disease associated with high mortality rates. This study aimed to describe the main causes of death in a case series of SLE patients attended in a single center in Colombia. METHODS We conducted a retrospective review and analysis of records of SLE patients who died between January 2011 and June 2017. We extracted the main causes of death and described variables associated with this outcome as well as variables associated with the disease and its treatment. RESULTS From a total of 1776 patients with SLE, we identified 49 fatal cases (89.8% women, n = 44). The average age at death was 40.6 years (SD 17.4), and patients had a median of 4.5 years (IQR 2-8) of disease duration. The main findings included lymphopenia in 44 patients (89.9%), biopsy-confirmed lupus nephritis (LN)-types IV and VI-in 38 (77.6%), catastrophic antiphospholipid syndrome (CAPS) in 8 (16.3%), and persistent hypocomplementemia (C3 and C4) in 8 (16.3%). The median SLE disease activity index (SLEDAI-2K) score at the time of death was 19 (IQR 11-39). The main cause of death was SLE activity and lupus-induced damage in 22 (44.9%) patients. CONCLUSION The main causes of death included SLE activity refractory to immunosuppressive treatment, and nosocomial bacterial infections. The patients who died had persistently high SLEDAI scores, types IV and VI LN, associated antiphospholipid syndrome, and persistent hypocomplementemia, requiring severe immunosuppression and prolonged hospitalization.
