Gamal S, Rady H, Sobhy N, Siam I, Soliman A, Elgengehy F. Mortality in a cohort of Egyptian systemic lupus erythematosus patients: A comparison with African, Arabic, and Mediterranean studies. Arch Rheumatol 2023; 38:468-476. [PMID: 38046246 PMCID: PMC10689014 DOI: 10.46497/archrheumatol.2023.9860] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 11/03/2022] [Indexed: 12/05/2023] Open
Abstract
Objectives The study aimed to examine the frequency, causes, and predictors of mortality in a cohort of Egyptian systemic lupus erythematosus (SLE) patients and compare mortality causes and the survival rate in our cohort to African, Arabic, and Mediterranean studies. Patients and methods In this retrospective study, a review of medical records of 563 SLE patients (516 females, 47 males; median of age: 32 [IQR: 26-38 years]; range, 14 to 63 years) fulfilling the 1997 American College of Rheumatology (ACR) criteria between January 2015 and December 2019 was done. The data extracted included demographic, clinical, and laboratory features, treatments used, disease activity as measured by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), and damage index as measured by Systemic Lupus International Collaborating Clinics (SLICC) damage index. Causes of mortality were also reported. Results Out of 563 reviewed medical records, 50 (8.9%) patients died. Infection (28%) and organ damage (18%) were the most commonly reported causes of death. Multivariate Cox regression analysis showed that patients with cardiac manifestations, renal failure, those receiving higher doses of either oral (in their last visit) or intravenous (higher cumulative pulse steroids) steroids were at increased risk of mortality (p=0.011, p<0.001, p=0.01, and p<0.001, respectively; 95% confidence intervals 7.2, 63.9, 1.2, and 1.09, respectively). The overall survival at 5, 10, 15, and 20 years was 96.6%, 93.3%, 91.0%, and 83.2%, respectively, and 56.2% at 25 years until the end of the follow-up. Conclusion Cardiac manifestations, renal failure, and higher steroid doses were independent predictors of mortality in our cohort. As in most African countries, infection was the main cause of death in our study; however, the mortality rate and the five-year survival among our cohort were better than in African (sub-Saharan) countries and similar to Arabic and Mediterranean countries.

Abstract
OBJECTIVES Application of 'treat-to-target' (T2T) in childhood-onset systemic lupus erythematosus (cSLE) may improve care and health outcomes. This initiative aimed to harmonise existing evidence and expert opinion regarding T2T for cSLE. METHODS An international T2T Task Force was formed of specialists in paediatric rheumatology, paediatric nephrology, adult rheumatology, patient and parent representatives. A steering committee formulated a set of draft overarching principles and points-to-consider, based on evidence from systematic literature review. Two on-line preconsensus meeting Delphi surveys explored healthcare professionals' views on these provisional overarching principles and points-to-consider. A virtual consensus meeting employed a modified nominal group technique to discuss, modify and vote on each overarching principle/point-to-consider. Agreement of >80% of Task Force members was considered consensus. RESULTS The Task Force agreed on four overarching principles and fourteen points-to-consider. It was agreed that both treatment targets and therapeutic strategies should be subject to shared decision making with the patient/caregivers, with full remission the preferred target, and low disease activity acceptable where remission cannot be achieved. Important elements of the points-to-consider included: aiming for prevention of flare and organ damage; glucocorticoid sparing; proactively addressing factors that impact health-related quality of life (fatigue, pain, mental health, educational challenges, medication side effects); and aiming for maintenance of the target over the long-term. An extensive research agenda was also formulated. CONCLUSIONS These international, consensus agreed overarching principles and points-to-consider for T2T in cSLE lay the foundation for future T2T approaches in cSLE, endorsed by the Paediatric Rheumatology European Society.

Abstract
Objectives: In this study, we aimed to assess serum levels of Cystatin C (Cys C) and beta-2 microglobulin (β2M) in juvenile systemic lupus erythematosus (JSLE) patients and to investigate their role as potential biomarkers of lupus nephritis (LN) and overall disease activity.
Patients and methods: Between December 2018 and November 2019, a total of 40 patients with JSLE (11 males, 29 females; mean age: 12.6±2.5 years; range, 7.5 to 16 years) and 40 age- and sex-matched controls (10 males, 30 females; mean age: 12.3±2.4 years; range, 7 to 16 years) were included in this study. Serum (s) Cys C and β2M levels were compared between the groups. The SLE Disease Activity Index (SLEDAI-2K), the renal SLEDAI (rSLEDAI), and the Renal Damage Index were used.
Results: JSLE patients had significantly elevated mean sCyc C and sβ2M levels (1.4±0.8 mg/mL and 2.8±0.9 mg/mL, respectively) compared to the controls (0.6±0.1 mg/mL and 2.0±0.2 mg/mL, respectively; p<0.00). The mean sCys C and sβ2M levels were significantly higher in the LN group, compared to non-LN patients (1.8±0.7 mg/mL and 3.1±1.0 mg/mL, respectively vs. 0.8±0.3 mg/mL and 2.4±0.6 mg/mL, respectively; p=0.002 and p=0.02, respectively). The sCys C levels had significant positive correlations with erythrocyte sedimentation rate (r=0.3, p=0.05), serum creatinine (r=0.41, p= 0.007), 24-h urinary protein (r=0.58, p<0.001), anti-double stranded deoxyribonucleic acid antibodies titers (r=0.55, p=0.002), extra-renal SLEDAI scores (r=0.36, p=0.04), rSLEDAI (r=0.46, p=0.002), and renal class (r=0.7, p=0.0001). Serum β2M levels were significantly negatively correlated with complement 4 levels (r=-0.31, p=0.04) and significantly positively correlated with extra-renal SLEDAI scores (r=0.3, p=0.05).
Conclusion: These findings confirm that sCys C and sβ2M levels are increased in JSLE patients in association with the overall active disease. However, sCys C level may act as a promising non-invasive biomarker for predicting kidney disease activity and biopsy classes in children with JSLE.

Abstract
Abstract
Background
The neuropsychiatric lupus erythematosus (NPSLE) is a severe complication of systemic lupus erythematosus (SLE) that is characterized by a variety of neurological manifestations involving both central and peripheral nervous system with variable mechanisms. This study aimed to investigate the frequency of NPSLE and its relation to other clinical and laboratory findings in SLE patients.
Results
We retrieved the medical records of 134 SLE patients during the study period; of them, 68 patients (50.7%) had NPSLE. Headache (55. 9%) was the most frequent NPSLE manifestation followed by seizures (54.4%), psychosis was the third most frequent one with a percentage of 41.2. The demographic data didn’t differ in patients with and without NPSLE. NPSLE patients had lower complement 3 (C3) (p = 0.025) and C4 (p = 0.008) levels, more lupus anticoagulant level (p = 0.033) and more frequency of antiphospholipid syndrome (p = 0.030). There was no statistical difference regarding the drug intake or other laboratory findings. Disease activity and damage indices didn’t differ in both groups.
Conclusion
The prevalence of NPSLE in this study was 50.7%. Headache, seizures and psychosis were the most frequent neuropsychiatric manifestations in the studied patients. SLE patients with neuropsychiatric manifestations had lower complement levels, higher lupus anticoagulant antibodies and antiphospholipid syndrome.

Abstract
AIM This study is a longitudinal multicenter study which aims to find the prevalence, the demographic data, survival and mortality rates of patients with systemic lupus erythematosus (SLE) in Oman. METHOD All Omani patients, pediatrics and adults diagnosed with SLE, who fulfill either the 1997 American College of Rheumatology or Systemic Lupus International Collaborating Clinics classifications criteria for SLE were included from January 2006 till February 2020. RESULTS In total 1160 patients were included in this cohort. Data analysis showed that patient's ages ranged from 2-82 years with female predominance and female-to-male ratio of 7:1 (87.7% female,12.3% male). The mean prevalence of SLE among different age groups was 38.8 (range 5-63 per 100 000 inhabitants). The mortality rate was found to be 5%. Male patients had significantly higher mortality rate than females (7.6% vs 5.4%, P value = .04). Sepsis was the commonest cause of mortality (34%). The coexistence of systemic sclerosis correlates significantly with death (P = .002). Survival analysis in our data showed 5, 10, 20, 40-year survival rates of 100%, 100%, 99% and 90% respectively for antinuclear antibody (ANA) positive patients and lower survival rate for ANA negative patients with 5,10, 20, 40-year survival rates of 100, 99%, 99% and 75%, respectively. CONCLUSION This study showed that the mean prevalence of SLE in Oman to be 38.8 (range 5-63) per 100 000 inhabitants. The 40-year survival rate among patients with positive ANA was found to be 90%, while patients with negative ANA had worse survival outcomes.

Abstract
Systemic lupus erythematosus is a rare lifelong multi-systemic autoimmune condition. Juvenile-onset SLE (JSLE) is recognized to have a more active disease course when compared with adult-onset disease and patients have a worse long-term survival. Kidney involvement occurs in over 50% of children and treatment decisions are guided by the histological classification. Several international groups have produced treatment protocols that rely on an intense period of immunosuppression to halt the acute kidney inflammatory process, followed by maintenance therapy with close observation for disease improvement and prompt evaluation of disease flares. A reduced glomerular filtration rate at presentation is predictive of later stage chronic kidney disease (CKD) in multivariate analysis. Kidney remission remains suboptimal with only 40-60% of patients achieving complete remission. Kidney flares are seen in over a third of patients. The rate of CKD 5 is reported to be up to 15% and the presence of lupus nephritis (LN) has an established link with an associated increase in mortality. In established kidney failure, transplantation seems to be the optimal kidney replacement modality for this group of patients, ideally after a period of disease quiescence. Modified outcome measures in clinical trials have demonstrated that biologic agents can be effective in this disease. Current biologic agents under investigation include obinutuzimab, belimumab, atacicept, anifrolumab, tocilizumab, eculizumab, dapirolizumab, and abatacept. Future research should focus on discovering early disease biomarkers, including surrogates for later cardiovascular disease, and evaluating biological agents as adjuncts to improve the rates of complete remission and subsequently influence the kidney outcome. The aim of this review article is to summarize the current kidney outcomes for this disease with a view to identifying key areas that may help to reduce the risk of long-term CKD.

Abstract
Abstract
Background
The aim of this study was to retrospectively investigate the prevalence and characteristics of neuropsychiatric (NP) involvement in a cohort of systemic lupus erythematosus (SLE) patients from a single tertiary center.
Results
Of 301 included patients’ medical records, the prevalence of NPSLE, that was defined according to the American College of Rheumatology Nomenclature of 1999, was 33.5% (101/301), of whom 10 (9.9%) were males. The mean age at the last visit of patients with NP involvement was 29.1 ± 8.2 years, whereas the mean age at onset was 21.9 ± 7.3 years, and the mean disease duration was 89.8 ± 59.4 months. The most common NP manifestations were psychosis [34/101 (33.7%)], followed by seizures [22/101 (21.8%)]. Compared to those without NPSLE, patients with NP involvement were characterized by having a younger age of onset (p < 0.001) had a longer disease duration (p = 0.02). Of the cumulative characteristics recorded, NPSLE patients showed a higher prevalence of cutaneous vasculitis (p = 0.002), discoid rash (p = 0.03), pleurisy and pleural effusion (p = 0.004, p = 0.03, respectively), pericarditis (p = 0.007), thrombocytopenia (p = 0.04), and secondary antiphospholipid (APS) (p = 0.04); however, there was no difference in any of the included serologic features between the two groups. Patients with NPSLE had a higher median disease activity score [Systemic Lupus Erythematosus Disease Activity Index-2 K (SLEDAI-2 K)] at the disease onset (p = 0.008), yet it was comparable to those without NP involvement at the last visit (p = 0.3). NPSLE patients demonstrated a higher median damage score (p < 0.001) that was assessed according to the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) score. NPSLE patients with secondary APS showed a higher prevalence of cerebrovascular accidents (CVA) (p < 0.001), while those without APS developed psychosis more frequently (p = 0.03).
Conclusion
Neuropsychiatric SLE patients (33.5%) demonstrated a younger age of onset, higher prevalence of secondary APS and distinct clinical characteristics, and had higher disease damage. APS-positive NPSLE patients had a higher prevalence of CVA, while APS-negative patients showed a higher prevalence of psychosis.

Abstract
OBJECTIVE The short-term outcomes of lupus nephritis (LN) are variable and unpredictable among individuals. We aimed to evaluate the clinical and histopathological features and short-term renal outcomes in LN patients. METHODS This was a prospective cohort study carried out at nephrology and rheumatology units in Egypt between 2018 and 2019. A total of 100 patients with biopsy-proven LN were studied. Patients were evaluated for response after six months. RESULTS The female-to-male ratio was 8.1:1. About 70% of patients were hypertensive at disease onset, with rates for classes I, II, III, IV, V and VI LN being 1%, 7%, 20%, 53%, 14% and 6%, respectively. Among the immunosuppressive drugs used for induction, mycophenolate mofetil (MMF) represented the most commonly used (44%) followed by cyclophosphamide (CYC; 37%). After six months of follow-up, about two thirds of patients achieved remission. There was no significant difference in remission rate between MMF and CYC. On multivariate analysis, serum creatinine (SCr) at presentation was the most significant predictor of renal recovery. According to the receiver operating characteristic curve, the cut-off value of SCr was 1.6 mg/dL, with a sensitivity of 76% and specificity of 71% predicting renal recovery. Repeat renal biopsy was needed in 10 patients; class and treatment strategy changed in 40% and 70% of them, respectively. CONCLUSION Our findings in Egyptian LN patients compare favourably with most studies.

Abstract
BACKGROUND Survival in systemic lupus erythematosus (SLE) has improved substantially in the last 50 years. The aim of the present study was to assess the evolution of the all-cause, cause-specific and age-specific standardised mortality ratios (SMRs) of patients with lupus in Ontario, Canada. PATIENTS AND METHODS Between 1971 and 2013, 1732 patients were followed in the Toronto Lupus Clinic. Causes of death were retrieved from death certificates, autopsy reports, hospital records or the records of the family physicians. They were categorised as atherosclerotic, infectious, malignancy, active lupus and others. For the calculation of the SMR (indirect standardisation method), data from the general population of Ontario, Canada were used (Statistics Canada). RESULTS Two hundred and forty-nine patients (205 women) died (infections 24.5%, atherosclerosis 15.7%, active lupus 13.3%, malignancy 9.6%); mean age was 53.2±16.6 years and mean disease duration 15.2±11.7 years. The all-cause SMR was substantially decreased from the 1970s (13.5, 95% CI 8.6 to 18.5) to recent years (2.2, 95% CI 1.4 to 3.1). Similar trends were observed for atherosclerosis, infections and malignancies over time. The all-cause age-specific SMR was particularly high in younger (19-39 years old) patients (SMR=12.4, 95% CI 9.7 to 15.1) as compared with individuals older than 40 years (SMR=3.1, 95% CI 2.6 to 3.6). The cause-specific SMR was also higher in younger patients, particularly for infections and malignancies. CONCLUSIONS The all-cause and cause-specific SMR significantly decreased over time, likely reflecting the advances in the management of SLE and certain comorbidities. The all-cause and cause-specific SMR was particularly high for younger patients (<40 years old).

OBJECTIVE The objective of this paper is to assess the role of gender on survival rate and causes of death and organ damage in systemic lupus erythematosus (SLE) patients in China from 2009 to 2015. METHODS We conducted a multicenter cohort study to analyze the differences in outcome data between male and female SLE patients. A group of 1494 SLE patients who fulfilled the 1997 American College of Rheumatology SLE classification criteria were enrolled in the Chinese Systemic Lupus Erythematosus Treatment and Research Group (CSTAR) registry from April 2009 to February 2010. All enrolled patients were followed up at least once per year from 2009 to 2015. For patients who could not attend the outpatient clinic, follow-up was conducted by telephone interview. We collected demographic data, clinical manifestations and damage scores (System Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)). Survival rates were evaluated using the Kaplan-Meier method. RESULTS This study included 1352 women and 142 men. The five-year survival rates were 92.0% for men and 97.6% for women. The survival rates of males were significant lower than for females ( p = 0.019). Male patients received methylprednisolone pulse therapy and cyclophosphamide significantly more than female patients ( p = 0.010). During follow-up, 12 male patients and 66 female patients died. The most common cause of death was infection (41.7%) for men and active SLE disease (27.3%) for women. At the end of the study, the major accumulated organ damages included renal (8.5%) and musculoskeletal (7.7%), and nervous system (5.6%) for men and renal (8.8%) and musculoskeletal (6.7%) for women. There were no significant differences in SDI scores between the two groups at baseline and at the end of the study. CONCLUSIONS Male SLE patients had lower survival rates than female patients. Male patients received more methylprednisolone pulse and cyclophosphamide therapy. The most common causes of death were infection for male patients and active SLE disease for female patients. The major accumulated organ damages were renal, musculoskeletal, and nervous system both for male and female SLE patients in China.
