Takamatsu R, Shimojima Y, Kishida D, Ichikawa T, Sekijima Y. The impact of normal serum complement levels on the disease classification and clinical characteristics in systemic lupus erythematosus. Adv Rheumatol 2022; 62:49. [PMID: 36575548 DOI: 10.1186/s42358-022-00283-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 12/19/2022] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Some patients have normal levels of complement during the diagnosis of systemic lupus erythematosus (SLE), although decreased serum levels of complement are a hallmark of the active phase of the disease. This study investigated the clinical characteristics, impact on the classification of SLE, and the prognosis of patients with SLE who had normal serum complement levels at initial diagnosis (N-com). METHODS We evaluated 21 patients with N-com and 96 patients with hypocomplementemia at the initial diagnosis of SLE (H-com). The classification rates among the American College of Rheumatology (ACR) 1997, Systemic Lupus International Collaborating Clinics (SLICC) 2012, European League Against Rheumatism (EULAR)/ACR 2019 criteria, and clinical and immunological involvements were compared between SLE patients with N-com and H-com. Relapse and organ damage based on the SLICC/ACR damage index were also evaluated. RESULTS The classification rates of SLE were not significantly different in the ACR, SLICC, and EULAR/ACR criteria between the N-com and H-com groups. Patients with N-com had no significant differences in the classification rates among the three criteria, whereas patients with H-com had lower classification rates in the ACR criteria than in the SLICC criteria. A lower incidence of renal manifestation, less positivity for anti-dsDNA antibody, and a higher incidence of fever were observed in patients with N-com than in those with H-com. The occurrence of relapse and organ damage was not significantly different between patients with N-com and H-com. CONCLUSION Patients with N-com were less involved in renal manifestation and anti-dsDNA antibody positivity but had a higher incidence of fever than those with H-com, while having no disadvantage in SLE classification processes. Serum complement levels at the initial diagnosis of SLE may not predict prognosis.

Attainment of low disease activity and remission targets reduces the risk of severe flare and new damage in childhood lupus. Rheumatology (Oxford) 2022; 61:3378-3389.

Abstract
OBJECTIVES To assess the achievability and effect of attaining low disease activity (LDA) or remission in childhood-onset SLE (cSLE). METHODS Attainment of three adult-SLE derived definitions of LDA (LLDAS, LA, Toronto-LDA), and four definitions of remission (clinical-SLEDAI-defined remission on/off treatment, pBILAG-defined remission on/off treatment) was assessed in UK JSLE Cohort Study patients longitudinally. Prentice-Williams-Petersen gap recurrent event models assessed the impact of LDA/remission attainment on severe flare/new damage. RESULTS LLDAS, LA and Toronto-LDA targets were reached in 67%, 73% and 32% of patients, after a median of 18, 15 or 17 months, respectively. Cumulatively, LLDAS, LA and Toronto-LDA was attained for a median of 23%, 31% and 19% of total follow-up-time, respectively. Remission on-treatment was more common (61% cSLEDAI-defined, 42% pBILAG-defined) than remission off-treatment (31% cSLEDAI-defined, 21% pBILAG-defined). Attainment of all target states, and disease duration (>1 year), significantly reduced the hazard of severe flare (P < 0.001). As cumulative time in each target increased, hazard of severe flare progressively reduced. LLDAS attainment reduced the hazard of severe flare more than LA or Toronto-LDA (P < 0.001). Attainment of LLDAS and all remission definitions led to a statistically comparable reduction in the hazards of severe flare (P > 0.05). Attainment of all targets reduced the hazards of new damage (P < 0.05). CONCLUSIONS This is the first study demonstrating that adult-SLE-derived definitions of LDA/remission are achievable in cSLE, significantly reducing risk of severe flare/new damage. Of the LDA definitions, LLDAS performed best, leading to a statistically comparable reduction in the hazards of severe flare to attainment of clinical remission.

Sun F, Zhao L, Wang H, Zhang D, Chen J, Wang X, Li T, Ye S. Risk factors of disease flares in a Chinese lupus cohort with low-grade disease activity. Lupus Sci Med 2022; 9:e000657. [PMID: 35606018 PMCID: PMC9125751 DOI: 10.1136/lupus-2022-000657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 05/08/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE Recurrent disease flare is one of the key problems in lupus patients. A Chinese Flare-Prevention Lupus Initiative Cohort (FLIC) was established. Risk factors of disease flare were evaluated accordingly. METHODS Patients with low-grade disease activity (the Safety of Estrogens in Lupus Erythematosus National Assessment-SLE Disease Activity Index (SELENA-SLEDAI) =≤6, daily prednisone ≤20 mg, no British Isles Lupus Assessment Group A or no more than one B organ domain score) from January 2014 to August 2020 were included in the FLIC. Disease flares were defined by the modified SELENA--SLEDAI Flare Index. Low disease activity status (LDAS) and remission were also assessed. The cumulative flare rate was estimated by an event per 100 person-years analysis. Cox proportional hazards models were performed to identify risk factors of subsequent disease flares after adjusting clinical confounders. Survival was assessed with the Kaplan-Meier method. RESULTS 448 eligible patients with low-grade disease activity were included in FLIC. During a mean follow-up of 30.4 months, 170 patients flared. The cumulative lupus flare rate was 22.2 events per 100 patient-years. Compared with patients without flare, those with lupus flares were taking more prednisone, had higher disease activity index and with less patients attained LDAS/remission at baseline. They also had higher rates of antiphospholipid antibodies (aPLs) and antiribosomal P antibody. Cox regression analysis confirmed that attainment of either LDAS or remission at baseline were independent protective factors against subsequent disease flare (LDAS but not in remission: HR 0.58, 95% CI 0.38~0.88; remission: HR 0.46, 95% CI 0.30~0.69), while aPL was a risk factor of lupus flares (HR 1.95, 95% CI 1.36~2.78). Kaplan-Meier curves indicated that attaining LDAS or remission and absence of aPL at baseline had the least flare risk. CONCLUSIONS In our real-world cohort study, not attaining LDAS or remission at baseline and aPL positivity was associated with higher risk of disease flares in patients with low-grade SLE.

Abstract
BACKGROUND Flares in patients with SLE, regardless of their severity, have been associated with damage accrual. However, their impact on health-related quality of life (HRQoL) has not been fully evaluated. In fact, disease activity is only minimally associated with HRQoL. OBJECTIVE To determine the association between flares and HRQoL. METHODS Patients from the Almenara Lupus Cohort were included. Visits occurring between December 2015 and February 2020 were evaluated. Flares were defined as an increase on the SLE Disease Activity Index 2000 (SLEDAI-2K) of at least 4 points; severe flares were those with a final SLEDAI-2K ≥12 and mild-moderate flares all the others. HRQoL was measured using the LupusQoL. Univariable and multivariable generalised estimating regression equations were performed, adjusting for possible confounders. Confounders were determined at one visit, whereas the outcome was determined on the subsequent visit; flares were determined based on the variation of the SLEDAI-2K between these visits. RESULTS Two hundred and seventy-seven patients were included; 256 (92.4%) were female, mean age at diagnosis was 36.0 (SD: 13.3) years and mean disease duration at baseline was 9.1 (SD: 7.1) years. Patients had mean of 4.8 (SD: 1.9) visits and a mean follow-up of 2.7 (1.1) years. Out of 1098 visits, 115 (10.5%) flares were defined, 17 were severe and 98 mild-moderate. After adjustment for possible confounders, only severe flares were associated with a poorer HRQoL in planning, pain, emotional health and fatigue. CONCLUSIONS Severe flares, but not mild-moderate, flares are associated with poorer HRQoL.

Abstract
OBJECTIVE To study the long-term outcomes, in the context of both mortality and organ damage in patients with systemic lupus erythematosus (SLE) in the Chinese SLE Treatment and Research group (CSTAR) registry cohort. METHODS Patients were enrolled from April 2009 to February 2010 and they were followed up. The demographic data, clinical manifestations, labs test results and imaging examinations, disease activity (SLEDAI-2K), damage scores (SLLIC/Damage Index [SDI]), and medications were collected. Data were censored at either the last clinic visit or telephonic interview. Survival rate was analyzed by Kaplan-Meier (KM) method. COX proportional hazard model was adopted to perform the analysis of predicting factors for mortality and organ damage. Logistic regression analysis was employed to discuss the relationship among mortality, organ damage, and flare. RESULTS A total of 2104 patients were recruited at baseline and 1494 patients were followed up. The cumulative 1-year, 3-year, and 5-year survival rates were 98.3%, 96.9%, and 95.7%, respectively. Seventy-eight patients died during follow-up, and the main causes of death were infection (34.6%), active disease (26.9%), cardiovascular and cerebrovascular events (5.13%), and malignancy (5.13%). At entry, 247 patients presented with irreversible organ damage and it increased to 398 patients at the endpoint. The major accumulated organ damages were kidney (25.9%), musculoskeletal disease (20.2%), neuropsychiatric disease (12.2%), and pulmonary damage (10.9%). Cox regression analysis further showed that male, late disease onset, delayed diagnosis (diagnosis from disease onset >1 year), baseline organ damage, and specific organ involvements predicted for higher mortality. In addition, early disease onset was a protecting factor for organ damage, and anti-SSA was an independent predicting factor for new organ damage. Logistic regression analysis showed that flare predicted for more organ damage. CONCLUSION The 5-year survival rate of Chinese SLE patients has improved and is comparable to Caucasians SLE patients. Disease flare impact on prognosis is the increasing risk of damage development. Early diagnosis, prevention for flare and damage to maintain remission, may improve outcome.

Predictors of unsuccessful hydroxychloroquine tapering and discontinuation: Can we personalize decision-making in systemic lupus treatment? Arthritis Care Res (Hoboken) 2020; 74:1070-1078. [PMID: 33369255 PMCID: PMC9544951 DOI: 10.1002/acr.24548] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 10/16/2020] [Accepted: 12/17/2020] [Indexed: 11/28/2022]
Abstract
Objective Hydroxychloroquine (HCQ) is a key systemic lupus erythematosus (SLE) drug, making concerns of drug shortages grave. Our objective was to evaluate factors associated with poor outcomes after HCQ taper or discontinuation in SLE. Methods We studied 5 Canadian SLE cohorts between 1999 and 2019, following patients from the date of HCQ tapering (cohort 1) or discontinuation (cohort 2). A composite outcome was defined as any of the following: a need for therapy augmentation, an increase (of at least 4 points) in the Systemic Lupus Erythematosus Disease Activity Index 2000 score, or hospitalization for SLE. In each cohort, multivariable Cox regression was used to identify demographic and clinical factors associated with time to the earliest of these events. A third cohort continuing to receive HCQ was also studied, to assess whether the same factors influenced the outcome even when the HCQ dose was unchanged. Results The poor outcome rate, per 100 person‐years, was 35.7 (95% confidence interval [95% CI] 31.6–40.3) in the HCQ taper cohort (n = 398), 29.0 (95% CI 25.5–33.0) in the discontinuation cohort (n = 395), and 16.1 (95% CI 13.2–19.6) in the maintenance cohort (n = 395). In patients tapering HCQ, baseline prednisone use was independently associated with greater risk of poor outcomes. In the discontinuation cohort, the risk of poor outcomes was greater for Black patients and those diagnosed with SLE at age ≤25 years. Among those maintaining HCQ, baseline immunosuppressive use and First Nations ethnicity were associated with poor outcomes. Conclusion We identified demographic and clinical factors associated with poor outcomes after HCQ taper/discontinuation. This information is critical in the current setting of potential shortages, but over the long term, such information could inform personalized therapies.

OBJECTIVES Data on flares in Asian patients with systemic lupus erythematosus (SLE) are scarce. Here, we aim to identify the baseline predictors of flares in a cohort of Southeast Asian patients with SLE. METHODS Consecutive adult patients with prevalent SLE according to the 1997 ACR or 2012 SLICC criteria were enrolled and followed three-monthly. Clinical and laboratory data were collected at every visit using a standardised protocol. Flares were defined using the SELENA-SLEDAI Flare Index (SFI). Baseline predictors of flare in patients with stable disease (SLE Disease Activity Index-2K (SLEDAI-2K) of ≤ 4) were determined using Cox proportional hazards. RESULTS Of the 210 patients recruited, 148 (70.5%) were Chinese. The median (IQR) SLEDAI-2K at entry was 2 (0-4) and the median (IQR) disease duration was 10 (4.4-16.4) years. At baseline, 152 (72.4%) patients had stable disease. After a median (IQR) follow-up of 31.5 (24.1-36.3) months, 109 (51.9%) flared. Stable patients who flared tended to be in the lowest tertile of age (HR 3.08, 95% CI 1.72-5.48, p < 0.01), had thrombocytopenia (HR 5.01, 95% CI 1.32-18.99, p = 0.02), hypocomplementemia (HR 3.35, 95% CI 1.54-7.30, p < 0.01) and had the highest baseline prednisolone doses (HR 2.39, 95% CI 1.28-4.46, p = 0.01). Conversely, patients in the lowest tertile of disease duration tended not to flare (HR 0.41, 95% CI 0.21-0.80, p = 0.01). CONCLUSION Flares are common in Asian SLE patients with initial stable disease. Close monitoring is needed for patients who are younger, with longer disease duration, thrombocytopenia, hypocomplementemia, or who required a higher baseline prednisolone dose.

Varicella zoster virus infections increase the risk of disease flares in patients with SLE: a matched cohort study. Lupus Sci Med 2019; 6:e000339. [PMID: 31413853 PMCID: PMC6667776 DOI: 10.1136/lupus-2019-000339] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2019] [Revised: 06/22/2019] [Accepted: 07/17/2019] [Indexed: 11/13/2022]
Abstract
Objective To explore whether varicella zoster virus (VZV) infection could increase the risk of disease flares in patients with SLE. Methods Patients who had VZV reactivations between January 2013 and April 2018 were included from the SLE database (n=1901) of Shanghai Ren Ji Hospital, South Campus. Matched patients with SLE were selected as background controls with a 3:1 ratio. Patients with SLE with symptomatic bacterial infections of the lower urinary tract (UTI) were identified as infection controls. Baseline period and index period were defined as 3 months before and after infection event, respectively. Control period was the following 3 months after the index period. Flare was defined by SELENA SLEDAI Flare Index. Kaplan-Meier analysis, Cox regression model and propensity score weighting were applied. Results Patients with VZV infections (n=47), UTI controls (n=28) and matched SLE background controls (n=141) were included. 16 flares (34%) in the VZV group within the index period were observed, as opposed to only 7.1% in UTI controls and 9.9% in background controls. Kaplan-Meier curve revealed that patients with a VZV infection had a much lower flare-free survival within the index period compared with the controls (p=0.0003). Furthermore, after adjusting for relevant confounders including baseline disease activity and intensity of immunosuppressive therapy, Cox regression analysis and propensity score weighting confirmed that VZV infection within 3 months was an independent risk factor for SLE flares (HR 3.70 and HR 4.16, respectively). Conclusions In patients with SLE, recent VZV infection within 3 months was associated with increased risk of disease flares.
