RESUMEN
OBJECTIVES: Our objective was to assess the overall and cause-specific standardized mortality ratios (SMRs) among patients diagnosed with systemic lupus erythematosus (SLE). METHODS: An exhaustive systematic review was undertaken, encompassing studies that scrutinized SMRs, both overall and for specific causes, in patients diagnosed with SLE compared to the general populace. The databases of PUBMED, EMBASE, and Cochrane were meticulously searched to collate relevant literature. Following this comprehensive search, a meta-analysis was executed to methodically assess all-cause, sex-specific, ethnicity-specific, and cause-specific SMRs in individuals with SLE. RESULTS: The inclusion criteria were met by 29 studies encompassing 72,342 patients with SLE and documenting 7352 deaths. The meta-analysis disclosed a pronounced 2.87-fold elevation in the SMR for all-cause mortality in SLE patients relative to the general population (SMR, 2.866; 95% confidence interval [CI], 2.490-3.242; p < .001). Region-specific assessments showed variable all-cause SMRs, with Europe reporting 2.607 (95% CI, 1.939-3.275; p < .001), Asia revealing 3.043 (95% CI, 2.082-4.004; p < .001), and particularly high SMRs noted in North America and Oceania. Gender-focused analyses presented a pooled SMR of 3.261 (95% CI, 2.674-3.848; p < .001) for females, and 2.747 (95% CI, 2.190-3.304; p < .001) for males. Evaluations specific to cause of death illustrated notably elevated SMRs for renal disease (SMR, 4.486; 95% CI, 3.024-5.948; p < .001), infections (SMR, 4.946; 95% CI, 4.253-5.639; p < .001), cardiovascular diseases (CVD) (SMR, 2.931; 95% CI, 1.802-4.061; p < .001), cerebrovascular accidents (CVA) (SMR, 1.588; 95% CI, 0.647-2.528; p = .001), and cancer (SMR, 1.698; 95% CI, 0.871-2.525; p < .001). CONCLUSIONS: This meta-analysis underscores a significant 2.87-fold elevation in the SMR among patients with SLE compared to the general population, transcending differences in sex or geographical regions. Moreover, an appreciable increase in mortality due to specific causes, including renal disease, infection, CVD, CVA, malignancy, and neuropsychiatric SLE, accentuates the imperative for targeted interventions to mitigate these elevated risks in SLE patients.

INTRODUCTION: The existing literature offers limited insights into the influence of Libman-Sacks Endocarditis (LSE) on inpatient outcomes in individuals with Systemic Lupus Erythematosus (SLE). This study aimed to explore the characteristics and prognosis of SLE patients with LSE and the impact of LSE in patients with SLE on inpatient outcomes including inpatient mortality, length of stay, acute heart failure, atrial fibrillation, and cerebrovascular accidents (CVA). METHODS: This study included adult patients who were hospitalized with SLE between the years 2019 and 2020, using the National Inpatient Sample (NIS) database. The total number of patients with a diagnosis of SLE in the years 2019 and 2020 in the NIS database was 150,411. Of those, 349 had a diagnosis of LSE. The study population was divided into two groups: one group with SLE and LSE, and another group with SLE but without LSE. RESULTS: Caucasians made up 54.9% of the patients with a diagnosis of SLE in our patient population, while African Americans made up 26.9% and the Hispanics accounted for 12.2%. Of patients with LSE, Caucasians and African Americans represented 42.9% each. Patients with a diagnosis of LSE had a higher inpatient mortality than those with SLE without LSE (aOR: 9.74 CI 1.12-84.79, p 0.04). Patients with SLE with LSE were more likely to have acute heart failure than those without LSE, although this was not statistically significant (aOR 1.18 CI 0.13-11.07, p 0.88). Similarly, patients with SLE with LSE were more likely to have atrial fibrillation than those without LSE (aOR 4.45 CI: 0.77-25.57, p 0.10). CVAs were significantly higher in SLE patients with LSE than those without LSE (aOR 141.43 CI 16.59-1205.52, p < .01). DISCUSSION: Patients who develop LSE were found to have significantly higher risks of inpatient mortality and cerebrovascular accidents. Early and precise detection of LSE in such patients may ensure timely intervention and prevention of the associated adverse outcomes. Further studies may attempt to develop screening methods for detection of LSE to effectively reduce morbidity and mortality associated with SLE.

ABSTRACT: Hydroxychloroquine (HCQ) and chloroquine (CQ) are foundational treatments for several systemic autoimmune rheumatic diseases, including systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Concerns regarding the risk of cardiac arrhythmia and death have been raised, yet the burden of HCQ and CQ-related cardiac toxicities remains unclear. A systematic literature search was conducted in the MEDLINE and Embase databases for articles published between the earliest date and April 2023 reporting cardiac conduction abnormalities in patients with systemic autoimmune rheumatic diseases taking HCQ or CQ. Meta-analysis was performed to calculate the difference in mean corrected QT (QTc) interval and odds ratio of prolonged QTc interval in those taking HCQ or CQ versus not. Of 2673 unique records, 34 met the inclusion criteria, including 70,609 subjects. Thirty-three studies reported outcomes in HCQ and 9 in CQ. Five studies reported outcomes in RA, 11 in SLE, and 18 in populations with mixed rheumatic diseases. Eleven studies reported mean QTc and OR for prolonged QTc for meta-analysis, all reporting outcomes in HCQ. There was a significant increase in mean QTc (10.29 ms, P = 0.458) among HCQ users compared to non-HCQ users in patients with RA. There was no difference in mean QTc between HCQ and non-HCQ users in other systemic autoimmune rheumatic diseases. When rheumatic diseases were pooled, HCQ users were more likely to have prolonged QTc compared to non-HCQ users (odds ratio 1.57, 95% CI, 1.19, 2.08). The results of this study suggest that clinicians should be aware of potential adverse cardiac events of HCQ and consider QTc monitoring for patients on HCQ for the treatment of systemic autoimmune rheumatic diseases.

OBJECTIVES: Age has a significant impact on systemic lupus erythematosus (SLE). However, data on very late-onset SLE (vlSLE) are scarce. We have compared the clinical and serological features of vlSLE patients with younger-onset patients. METHODS: We assessed the clinical and laboratory data of all patients fulfilling SLE classification criteria evaluated at a university hospital from 1978 to 2023. Patients were divided into 4 groups according to age at diagnosis: juvenile SLE (jSLE <8 years); adult SLE (aSLE 18-49 years); late SLE (lSLE 50-59 years); vlSLE (≥60 years). RESULTS: 845 patients were enrolled. The jSLE, aSLE, lSLE, and vlSLE groups included 153, 630, 47, and 15 patients, respectively. The vlSLE group tended to have a lower female-to-male ratio (4:1; p=0.282), was mainly Caucasian (93.3%; p<0.001), and had the lowest survival time (20.3 years; p<0.001). vlSLE patients had the lowest prevalence of positive anti-dsDNA antibodies (26.7%; p=0.010) and low C3 levels (13.3%; p<0.001). Although arthritis was less common among vlSLE patients (73.3%; p=0.043), they more commonly developed Sjögren's syndrome (SS 33.3%; p<0.001) and rheumatoid arthritis (RA 13.3%; p<0.001). Infections and malignancy were the main causes of death. CONCLUSIONS: Compared with younger patients, in vlSLE, female predominance is less pronounced. Arthritis, anti-dsDNA antibodies and low C3 levels are less frequent. SS and RA are more common. Despite lower disease activity, vlSLE patients have the lowest survival rate. While uncommon, SLE should not be excluded as a possible diagnosis in the elderly.

Background/aim: Immunosuppressive and immunomodulatory treatments developed in recent years as a result of a better understanding of the pathophysiology of systemic rheumatic diseases (SRDs) improve the prognosis. Despite medical advances, individuals with SRDs at any stage may require intensive care and have a high mortality rate. The aim of this study was to investigate the demographic and clinical characteristics of patients with rheumatic diseases admitted to the intensive care unit (ICU), and the factors associated with the risk of mortality. Materials and methods: This was a retrospective, cross-sectional study that included patients with rheumatic diseases in the medical ICU. Factors of ICU 28-day mortality were identified by multiple-variable logistic analysis. Results: A total of 127 patients with SRDs admitted to the medical ICU were enrolled. Systemic lupus erythematosus (SLE) (32.3%) was the most common diagnosis of SRDs in patients admitted to the ICU. The reasons for admission to the ICU were combined infection and primary SRD flare-up (35.4%), primary SRD flare-up (22%), SRD-unrelated reasons (22%), infection (17.3%), drug side effects (3.9%), and SRD-related complications (0.8%). The most common organ dysfunctions before (49.6%) and during (77.2%) admission to ICU were in the respiratory system. The 28-day mortality was 78 (61.4%). While the maximum procalcitonin, serum lactate, and blood urea nitrogen (BUN) levels were higher in the nonsurvivor group, the platelet and serum albumin levels were statistically significantly lower than those in the survivor group (p < 0.05). Acute respiratory failure (ARF), the presence of septic shock, the need for invasive mechanical ventilation (IMV), BUN level, and low platelet-lymphocyte ratio (PLR) were significant in the final multiple-variable model. Conclusion: Significant predictors of mortality in patients with rheumatic diseases may include ARF, septic shock, the need for IMV, and high BUN and low PLR levels.

OBJECTIVE: We analysed the incidence of, the specific outcomes and factors associated with COVID-19-associated organ failure (AOF) in patients with systemic lupus erythematosus (SLE) in France. METHODS: We performed a cohort study using the French national medical/administrative hospital database for the January 2011-November 2020 period. Each patient with SLE diagnosed in a French hospital with a COVID-19-AOF until November 2020 was randomly matched with five non-SLE patients with COVID-19-AOF. We performed an exact matching procedure taking age ±2 years, gender and comorbidities as matching variables. COVID-19-AOF was defined as the combination of at least one code of COVID-19 diagnosis with one code referring to an organ failure diagnosis. RESULTS: From March to November 2020, 127 380 hospital stays in France matched the definition of COVID-19-AOF, out of which 196 corresponded with patients diagnosed with SLE. Based on the presence of comorbidities, we matched 908 non-SLE patients with COVID-19-AOF with 190 SLE patients with COVID-19-AOF. On day 30, 43 in-hospital deaths (22.6%) occurred in SLE patients with COVID-19-AOF vs 198 (21.8%) in matched non-SLE patients with COVID-19-AOF: HR 0.98 (0.71-1.34). Seventy-five patients in the SLE COVID-19-AOF group and 299 in the matched control group were followed up from day 30 to day 90. During this period, 19 in-hospital deaths occurred in the SLE group (25.3%) vs 46 (15.4%) in the matched control group; the HR associated with death occurring after COVID-19-AOF among patients with SLE was 1.83 (1.05-3.20). CONCLUSIONS: COVID-19-AOF is associated with a poor late-onset prognosis among patients with SLE.

INTRODUCTION: The aim of this study was to assess the differences between childhood-onset and adult-onset systemic lupus erythematosus (cSLE and aSLE) for clinical manifestations and mortality using a meta-analytic approach. METHODS: The PubMed, EMBASE, and the Cochrane library were searched for eligible studies published between January 1982 and March 2021. The odds ratio (OR) with 95% confidence interval was used to calculate the pooled effect estimates using the random-effects model. RESULTS: Thirty-four studies involving 21,946 SLE patients were included. cSLE was associated with an increased risk of malar rash (OR: 1.64; p < 0.001), ulcers/mucocutaneous involvement (OR: 1.22; p = 0.039), general neurological involvement (OR: 1.52; p < 0.001), seizures (OR: 1.92; p < 0.001), general renal involvement (OR: 2.08; p < 0.001), proteinuria (OR: 1.35; p = 0.015), urinary cellular casts (OR: 1.67; p = 0.047), fever (OR: 2.31; p < 0.001), anemia (OR: 1.91; p < 0.001), thrombocytopenia (OR: 1.41; p < 0.001), leucopenia (OR: 1.57; p = 0.017), lymphadenopathy (OR: 2.40; p < 0.001), and cutaneous vasculitis (OR: 1.72; p = 0.001) as compared with aSLE. Moreover, cSLE versus aSLE was associated with a reduced risk of articular manifestations (OR: 0.63; p = 0.001), pulmonary involvement (OR: 0.54; p = 0.001), and pleuritis (OR: 0.61; p < 0.001). There were no significant differences between cSLE and aSLE for mortality risk (OR: 1.20; p = 0.203). CONCLUSION: We found that certain clinical manifestations of SLE are different in cSLE and aSLE. Moreover, the mortality risk of cSLE and aSLE was not significantly different.

OBJECTIVE: To investigate all-cause and cause-specific mortality in SLE patients between two time periods, 1997-2005 and 2006-14. METHODS: We used an administrative health database from the province of British Columbia, Canada to match all incident SLE patients to 10 non-SLE individuals on sex, age and index date. Cohorts were divided into two subgroups, according to diagnosis year: early cohort 1997-2005 and late cohort 2006-14. The outcome was death [all-cause, renal disease, cancer, infection, cardiovascular disease (CVD) and other]. Hazard ratios (HR) and 95% CIs were estimated using univariate and multivariable Cox models. RESULTS: Among 6092 SLE patients and 60 920 non-SLE individuals, there were 451 and 1910 deaths, respectively. The fully adjusted all-cause mortality HR (95% CI) in the overall SLE cohort was 1.85 (1.66, 2.06), with no statistically significant improvement between early and late cohorts [1.95 (1.69, 2.26) vs 1.74 (1.49, 2.04)]. There was excess mortality from renal disease [3.04 (2.29, 4.05)], infections [2.74 (2.19, 3.43)] and CVD [2.05 (1.77, 2.38)], but not cancer [1.18 (0.96, 1.46)], in the overall SLE cohort. There was no statistically significant improvement in cause-specific mortality between early and late cohorts for renal disease [3.57 (2.37, 5.36) vs 2.65 (1.78, 3.93)], infection [2.94 (2.17, 3.98) vs 2.54 (1.84, 3.51)] and CVD [1.95 (1.60, 2.38) vs 2.18 (1.76, 2.71)]. There was no increase in cancer-related mortality in either cohort [1.27 (0.96, 1.69) vs 1.10 (0.82, 1.48)]. CONCLUSION: This population-based study demonstrates a persisting mortality gap in all-cause and cause-specific deaths in SLE patients, compared with the general population.

OBJECTIVE: To evaluate the risk of severe infection and infection-related mortality among patients with newly diagnosed SLE. METHODS: We conducted an age- and gender-matched cohort study of all patients with incident SLE between 1 January 1997 and 31 March 2015 using administrative health data from British Columbia, Canada. Primary outcome was the first severe infection after SLE onset necessitating hospitalization or occurring during hospitalization. Secondary outcomes were total number of severe infections and infection-related mortality. RESULTS: We identified 5169 SLE patients and matched them with 25 845 non-SLE individuals from the general population, yielding 955 and 1986 first severe infections during 48 367 and 260 712 person-years follow-up, respectively. The crude incidence rate ratios for first severe infection and infection-related mortality were 2.59 (95% CI: 2.39, 2.80) and 2.20 (95% CI: 1.76, 2.73), respectively. The corresponding adjusted hazard ratios were 1.82 (95% CI: 1.66, 1.99) and 1.61 (95% CI: 1.24, 2.08). SLE patients had an increased risk of a greater total number of severe infections with crude rate ratio of 3.24 (95% CI: 3.06, 3.43) and adjusted rate ratio of 2.07 (95% CI: 1.82, 2.36). CONCLUSION: SLE is associated with increased risks of first severe infection (1.8-fold), a greater total number of severe infections (2.1-fold) and infection-related mortality (1.6-fold).

OBJECTIVE: To evaluate the association and dose-response pattern between antimalarial drugs and overall and cause specific mortality in SLE patients. METHODS: Medical records including information on HCQ/chloroquine (CQ) prescription were extracted from Jiangsu Lupus database. The database was designed to collect data from SLE patients that first-hospitalized during 1999-2009 in Jiangsu province, China, and a follow-up for survival status was performed in 2010 and 2015. Cox and restricted cubic spline models were used to estimate the hazard ratio and 95% CI. RESULTS: We identified 221 deaths among 2446 SLE patients in total. Compared with non-users, decreased overall mortality was associated with either HCQ or CQ users, with adjusted hazard ratio (95% CI) of 0.49 (0.35, 0.67) and 0.49 (0.27, 0.87), respectively. The association between HCQ/CQ and overall mortality was similar across subgroups, such as patients with comorbidities and organ involvements. Interestingly, both the time and the daily dosage of HCQ/CQ use were related to decreased mortality of SLE in a linear dose-response relationship. In cause specific analyses, HCQ/CQ was inversely associated with death from renal insufficiency and other organ (cardiopulmonary, gastrointestinal and haematological) involvements, with adjusted hazard ratio (95% CI) of 0.23 (0.09, 0.55) and 0.25 (0.10, 0.62), respectively, yet it was not significantly associated with mortality from infection and neuropsychiatric involvements. CONCLUSION: Antimalarial drugs were associated with lower risk of SLE mortality, especially renal insufficiency- and other organ involvement-related death. The protective effects for survival might be augmented by adherence and full dosage of these drugs.

OBJECTIVE: To estimate the risk of mortality in the Finnish incident SLE cohort in a 16-year period compared with the general population. METHODS: Adults with new-onset SLE between 1 January 2000 and 31 December 2014 identified from the national drug reimbursement register and their individually matched controls from the Population Register Centre were followed up until death or 31 December 2015. Data on deaths were retrieved from the national causes of death register. Comorbidities and education were obtained by linkage to the other national registries. RESULTS: A total of 1006 patients with incident SLE and 3005 population controls were found (mean follow-up 8.6 years). Of these, 98 SLE patients subsequently died. Their 5 -, 10-, and 15-year survival rates were 95.0% (95% CI: 93.3, 96.2), 88.8% (86.2, 91.0), and 82.1% (77.6, 85.8), respectively. Crude hazard ratio (HR) was 1.61 (95% CI: 1.26, 2.06), adjusted for education level was almost the same 1.61 (95% CI: 1.26, 2.05). After adjustment for comorbidities and education at baseline, the difference in mortality disappeared: HR 1.14 (95% CI: 0.88, 1.48). The leading causes of death were cardiovascular diseases (CVDs) (33%), malignancies (27%) and neurological diseases (10%). Subhazard ratio for CVD deaths was 1.28 (95% CI: 0.85, 1.93), adjusted for comorbidities and education 0.88 (95% CI: 0.56, 1.39). CONCLUSIONS: These results suggest that the increased mortality in SLE patients is highly associated with comorbidities present at diagnosis. This underlines the importance to screen and treat comorbidities and disease actively without delays.

OBJECTIVES: We wanted to estimate the magnitude of the risk from all-cause, cause-specific and sex-specific mortality in patients with SLE and relative risks compared with matched controls and to evaluate the influence of exposure to medication on risk of mortality in SLE. METHODS: We conducted a population-based cohort study using the Clinical Practice Research Datalink, Hospital Episode Statistics and national death certificates (from 1987 to 2012). Each SLE patient (n = 4343) was matched with up to six controls (n = 21 780) by age and sex. Cox proportional hazards models were used to estimate overall and cause-specific mortality rate ratios. RESULTS: Patients with SLE had a 1.8-fold increased mortality rate for all-cause mortality compared with age- and sex-matched subjects [adjusted hazard ratio (HR) = 1.80, 95% CI: 1.57, 2.08]. The HR was highest in patients aged 18-39 years (adjusted HR = 4.87, 95% CI: 1.93, 12.3). Mortality rates were not significantly different between male and female patients. Cumulative glucocorticoid use raised the mortality rate, whereas the HR was reduced by 45% with cumulative low-dose HCQ use. Patients with SLE had increased cause-specific mortality rates for cardiovascular disease, infections, non-infectious respiratory disease and for death attributable to accidents or suicide, whereas the mortality rate for cancer was reduced in comparison to controls. CONCLUSION: British patients with SLE had a 1.8-fold increased mortality rate compared with the general population. Glucocorticoid use and being diagnosed at a younger age were associated with an increased risk of mortality. HCQ use significantly reduced the mortality rate, but this association was found only in the lowest cumulative dosage exposure group.

INTRODUCTION: Systemic lupus erythematosus (SLE) is a complex autoimmune pathology that can involve any organ. Lupus-related acute pancreatitis (AP) is, together with lupus mesenteric vasculitis, an important cause of SLE-induced acute abdominal pain. METHODS: A literature search was conducted using the terms "Pancreatitis" and "Lupus Erythematosus, Systemic" on PubMed/Medline and Web of Science from January 2007 to January 2020. Clinical characteristics, diagnostic approach, and treatment principles in SLE-related AP are presented in this review. RESULTS: Mainly retrospective reports were identified. The reported incidence of SLE-associated AP ranges from 0.9 to more than 5% of patients. A total of 264 SLE patients were found in the selected research, with a net female predominance (sex ratio 9:1) and mean age of 31.4 years. Abdominal pain was virtually present in all cases. AP occurrence was more frequent in SLE patients with short disease duration, high activity scores, and multiorgan involvement. The AP definition was based on currently available guidelines and after exclusion of any other known causes (including iatrogenic, i.e. drugs), a diagnosis of "idiopathic" SLE-related AP might be sustained. Management is difficult, as there is no standardized therapeutic approach. Of note, glucocorticoid use remains still controversial as, especially for high doses, subsequent pancreatic injury may occur. Monitoring serum lipase levels after high dose steroids might be considered. One study reported beneficial prognostic effect of plasma exchange. Moreover, AP in SLE might raise awareness about macrophage activation syndrome association. Mortality up to one third of AP cases in SLE was reported. CONCLUSION: The SLE-related AP is a rare, but severe, life-threatening complication. Corticosteroids must be used with caution. Plasma exchange could be considered in selected cases.

OBJECTIVES: To determine the outcome of subclinical lupus myocarditis (LM) over twelve months with regards to: mortality; incidence of clinical LM and change in imaging parameters (echocardiography and cardiac magnetic resonance [CMR]). To evaluate the impact of immunosuppression on CMR evidence of myocardial tissue injury. METHODS: SLE patients with and without CMR evidence of myocardial injury (as per 2009 Lake Louise criteria [LLC]) were included. Analysis at baseline and follow-up included: clinical evaluation, laboratory and imaging analyses (echocardiography and CMR). Clinical LM was defined as clinical features of LM supported by echocardiographic and/or biochemical evidence of myocardial dysfunction. Subclinical LM was defined as CMR myocardial injury without clinical LM. RESULTS: Forty-nine SLE patients were included with follow-up analyses (after 12 months) available in 36 patients. Twenty-five patients (51%) received intensified immunosuppressive therapy during follow-up for indications related to SLE. Disease activity (SLEDAI-2K) improved (p < 0.001) from 13 (median;IQR:9-20) to 7 (3-11). One patient without initial CMR evidence of myocardial injury developed clinical LM. Mortality (n = 10) and SLE clinical features were similar between patients with and without initial CMR myocardial injury. Echocardiographic left ventricular ejection fraction (LVEF) (p = 0.014), right ventricular function (p = 0.001) and wall motion abnormalities (p = 0.056) improved significantly but not strain analyses nor the left LV internal diameter index. CMR mass index (p = 0.011) and LVEF (p < 0.001) improved with follow-up but not parameters identifying myocardial tissue injury (LLC). A trend towards a reduction in the presence of CMR criteria was counterbalanced by persistence (n = 7) /development of new criteria (n = 11) in patients. Change in CMR mass index correlated with change in T2-weighted signal (myocardial oedema) (r = 386;p = 0.024). Intensified immunosuppressive therapy had no significant effect on CMR parameters. CONCLUSION: CMR evidence of subclinical LM persisted despite improved SLEDAI-2K, serological markers, cardiac function and CMR mass index. Subclinical LM did not progress to clinical LM and had no significant prognostic implications over 12 months. Immunosuppressive therapy did not have any significant effect on the presence of CMR evidence of myocardial tissue injury. Improvement in CMR mass index correlated with reduction in myocardial oedema and may be used to monitor SLE myocardial injury.

OBJECTIVE: To examine the age differences in secular trends in black-white disparities in mortality from systemic lupus erythematosus (SLE) among women in the United States from 1988 to 2017. METHODS: We used mortality data to calculate age-specific SLE and all-causes (as reference) mortality rates and black/white mortality rates ratios among women from 1988 to 2017. Annual percent change was estimated using joinpoint regression analysis. RESULTS: We identified 10,793 and 4,165,613 black women and 19,455 and 31,129,528 white women who died between 1988 and 2017 from SLE and all-causes, respectively. The black/white SLE mortality rate ratio according joinpoint regression model was 6.6, 7.2, 4.4, and 1.4 for decedents aged 0-24, 25-44, 45-64, and 65+ years in 1988 and was 7.2, 5.9, 4.1, and 1.9, respectively in 2017. No significant decline trend was noted and the annual percent change was 0.3%, -0.7%, -0.2%, and 1.0%, respectively. On the contrast, the black/white all-causes mortality rate ratio was 2.0, 2.5, 1.8, and 1.0, respectively in 1988 and was 1.7, 1.3, 1.5, and 0.9, respectively in 2017, a significant decline trend was noted in each age group. CONCLUSIONS: Black adults, youths and adolescents had four to seven times higher SLE mortality rates than their white counterparts and the black-white disparities persisted during the past three decades. On the contrast, black women had less than two times higher all-causes mortality rates than their white counterparts and black-white disparities significantly diminish during the past three decades.

OBJECTIVE: To evaluate the predictors of mortality, mortality rate, and causes of death in patients with lupus nephritis (LN) depending on final renal function. METHODS: The cohort included 401 Korean patients diagnosed with LN between 1985 and 2019. We retrospectively analyzed the clinical and laboratory indices, treatment response, and the final renal function. The final renal function was defined by the last stable level of eGFR measured in an out-patient department more than 3 times before death occurred and was categorized into five groups depending on CKD stage. RESULTS: The median follow-up time after the diagnosis of LN was 131 months. No difference in baseline demographic characteristics and laboratory findings was found except for the proportion of Hb less than 10 mg/dl and baseline eGFR (p = 0.011 and 0.037). We found no significant differences in therapeutic parameters, but all the response parameters including treatment response at 6 months (p = 0.004) and 12 months (p = 0.004), time to remission (p < 0.001), final renal response (p < 0.001), and the final renal function (p < 0.001) differed significantly between the two groups. In multivariate Cox proportional hazards analysis, the final renal function was an independent risk factor predicting mortality. The main causes of death were infection and SLE flare. Contrary to existing knowledge, SLE flare also triggered mortality in a few patients with LN progressed to end-stage renal disease (ESRD). Only two cases of mortality occurred in the kidney transplantation (KT) group (n = 25) with a median follow-up period of 224 months. The overall mortality rates calculated using the Kaplan-Meier method were 6.8%, 10.3%, 19.7%, and 28.0% at 5, 10, 20, and 30 years, respectively. CONCLUSION: Renal function deterioration was an independent determinant of mortality in Korean patients with LN. SLE flare also caused mortality in patients with LN who required maintenance dialysis, suggesting the benefit of KT on lupus activity and survival.

OBJECTIVES: To investigate the relationship between smoking history and pack-year exposure on the rate of end-organ damage in systemic lupus erythematosus (SLE). METHODS: The SLE incident cohort included patients who met American College of Rheumatology (ACR) 1997 or SLE International Collaborating Clinics (SLICC) 2012 SLE criteria and had rheumatology encounters at a US academic institution (2008-16). The primary outcome was median time to SLICC/ACR damage index (SLICC/ACR-DI) increase or death. Main explanatory variables were smoking status and pack-years. Covariates included age, sex, race, ethnicity, receipt of Medicaid, neighborhood area deprivation index, and baseline SLE damage. Damage increase-free survival was evaluated by smoking status and pack-years using Kaplan-Meier and Cox proportional hazards methods. RESULTS: Patients of Black race and Medicaid recipients were more commonly current smokers (p's < 0.05). Former smokers were older and more likely to have late-onset SLE (54% versus 33% of never and 29% of current smokers, p = 0.001). Median time to SLICC/ACR-DI increase or death was earlier in current or former compared to never smokers (4.5 and 3.4 versus 9.0 yrs; p = 0.002). In multivariable models, the rate of damage accumulation was twice as fast in current smokers (HR 2.18; 1.33, 3.57) and smokers with a >10 pack-year history (HR 2.35; 1.15, 3.64) versus never smokers. CONCLUSIONS: In this incident SLE cohort, past or current smoking predicted new SLE damage 4-5 years earlier. After adjustment, current smokers and patients with a pack-year history of >10 years accumulated damage at twice the rate of never smokers.

INTRODUCTION: Systemic lupus erythematosus (SLE) is a relapsing and remitting multiorgan disease associated with significant morbidity and mortality. The survival rate of patients with SLE has recently improved, which was associated with increased morbidity and hospitalization rates. Therefore, this study aimed to examine the rate and causes of hospitalization in patients with SLE and explore factors associated with increased length of stay (LOS). METHODS: Patients who visited rheumatology clinics (Tawam hospital, United Arab Emirates (UAE)) and fulfilled the American College of Rheumatology (ACR) SLE criteria were identified. Retrospective charts were reviewed to determine previous admissions. Demographic data, reason for hospitalization, duration of hospitalization, intensive care unit (ICU) admission, number of specialist consultations, medications used, and SLE characteristics at time of admission were collected. The hospitalization rate was calculated as the number of hospitalized patients divided by the total number of patients with the disease. We performed multivariable regression analysis for factors associated with increased LOS. RESULTS: A total of 91 patients with SLE (88 women and 3 men) met the inclusion criteria with a mean disease duration of 10.2 years (SD 5.5). A total of 222 admissions were identified, and 66 of 91 patients were admitted at least once. The mean crude hospitalization rate calculated was 29.8%. The primary reason for admission was pregnancy (29%), SLE activity (24%), and infection (20%). When combining primary and secondary reasons, the proportion of admissions due to SLE activity increased to 32%. The mean LOS was 5.9 (SD 6.0) days. About 7% of admitted patients required ICU admission. In multivariable analysis, patients with lupus nephritis, complications during hospitalization, and increased number of specialists consultations and who were admitted to ICU and started new medication were all associated with increased LOS. CONCLUSION: A significant proportion of patients with SLE were hospitalized during their disease course. The hospitalization rate in this study appears to be higher than those reported elsewhere. Disease flare is the leading cause of admission in patients with SLE in this relatively young cohort. Lupus nephritis has been found to be significantly related to longer LOS. Measurements taken to reduce the incidence and severity of flares would likely decrease hospitalization rate and LOS in patients with SLE.

BACKGROUND: Systemic Lupus Erythematosus (SLE) an autoimmune rheumatic disease with a complex pathogenesis, remains potentially life-threatening. SLE patients have increased morbidity and premature mortality compared to non-SLE patients. The five-year survival rate has improved from <50% in the 1950s to >90% in the 1980s. Lupus patients still have a mortality risk three times that of the general population. OBJECTIVES: To provide a detailed analysis of the causes of death, main characteristics and trends in the management of the deceased SLE patients from the lupus clinic at the University College London Hospital (UCLH); during the past four decades. METHODS: This was a non-interventional, retrospective study based on historical real-world data from paper and electronic records of patients followed up at UCLH. The analysis focused on data collected between 1st January 1978 and 31th December 2018. We collected the: causes of death, duration of disease, key laboratory and clinical parameters and the treatment received. We compared the results from the four decades to ascertain trends in the causes of mortality. All statistical analyses were performed using the Statistical Package for Social Sciences (SPSS), version 22.0. The 95% confidence intervals for the means of data were calculated. RESULTS: 111 SLE patients (15%), died during follow-up. Their median age was 51 years (interquartile range (IQR) = 38-63 years) and the median duration of disease, 15 years (IQR = 8.5-24 years). The main causes of death in the past 40 years were infection (31.7%), cancer (26.7%) and cardiovascular disease (CVD) (21.8%). 93.6% of these patients were immunosupressed. During the 40-year period, there were several therapeutic developments notably the introduction of mycophenolate mofetil (MMF) and rituximab; the latter initially only given to patients when more conventional inmunosupressants had failed, but more recently offered to patients at diagnosis. There was a statistically significant increase in the use of hydroxycloroquine (HCQ), MMF and rituximab. In contrast, the use of Azathioprine (AZA) and steroids, hardly changed over time. CONCLUSIONS: This retrospective review shows how epidemiological factors, causes of death and treatment of SLE patients have changed during the last 40 years in the UCLH cohort.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease with manifestations that vary widely in severity. Although minority populations are at higher risk for SLE and have more severe outcomes (1), population-based estimates of mortality by race and ethnicity are often lacking, particularly for Asian and Hispanic/Latino persons. Among 812 patients in the California Lupus Surveillance Project (CLSP) during 2007-2009 (2,3), who were matched to the 2007-2017 National Death Index (NDI), 16.6% had died by 2017. This proportion included persons of White (14.4%), Black (25%), Asian (15.3%), and Hispanic/Latino (15.5%) race/ethnicity. Standardized mortality ratios (SMRs) of observed-to-expected deaths among persons with SLE within each racial/ethnic group were 2.3, 2.0, 3.8, and 3.9, respectively. These findings provide the first population-based estimates of mortality among Asian and Hispanic/Latino persons with SLE. Coordination of robust care models between primary care providers and rheumatologists could ensure that persons with SLE receive a timely diagnosis and appropriate treatments that might help address SLE-associated mortality.
