[PMID: 37341643 PMCID: PMC10765162 DOI: 10.1093/rheumatology/kead297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 05/27/2023] [Accepted: 06/06/2023] [Indexed: 06/22/2023] Open
Abstract
OBJECTIVES Late-onset SLE is usually milder and associated with lower frequency of LN and neuropsychiatric manifestations. The diagnosis of NPSLE is especially challenging in older patients because of increased incidence of neurological comorbidities. We performed a systematic review and meta-analysis to evaluate the differences in NPSLE manifestations in early-onset (<50-year-old) vs late-onset (≥50-year-old) SLE patients. METHODS A literature search was performed using the PubMed, Web of Science and Cochrane Library databases. Studies available in English (1959-2022) including a late-onset SLE comparison group and evaluating the frequency of NPSLE were eligible. A forest plot was used to compare odds ratios (95% CI) of incidence and manifestations of NPSLE by age groups. Study heterogeneity was assessed using I2 statistics. RESULTS A total of 44 studies, including 17 865 early-onset and 2970 late-onset SLE patients, fulfilled our eligibility criteria. CNS involvement was reported in 3326 patients. Cumulative NPSLE frequency was higher in the early-onset group than in the late-onset group (OR: 1.41, 95% CI: 1.24, 1.59, P < 0.0001). In early-onset SLE patients, seizures (OR: 1.68, 95% CI: 1.27, 2.22) and psychosis (OR: 1.72, 95% CI: 1.23, 2.41) were more common than in late-onset SLE patients (P values, 0.0003 and 0.0014, respectively). Peripheral neuropathy was more commonly reported in the late-onset SLE group than in the early-onset SLE group (OR: 0.64, 95% CI: 0.47, 0.86, P = 0.004). CONCLUSION Our meta-analysis revealed that the frequencies of overall NPSLE, seizures, and psychosis were less common in late-onset SLE patients than in early-onset SLE patients. In contrast, peripheral neuropathy was more common in the late-onset SLE group.

Abstract
Background Arguments still exist on prognosis of late-onset SLE, especially their kidney function. The purpose of this study was to investigate long-term kidney outcomes in patients with late-onset lupus nephritis (LN). Methods A retrospective long-term cohort study was conducted in adult Chinese patients with LN. The patients were divided into late- (>50 years) and early-onset (<50 years) LN groups. The baseline characteristics, especially the kidney pathological characteristics, were compared. The cohort was followed-up for kidney outcome defined as doubling of serum creatinine or ESRD. Cox regression analysis was used to examine the association between late onset LN and its outcomes. Results A total of 1,264 patients were recruited, who were assigned to late-onset LN with 102 patients and early-onset LN with 1,162 patients. The late-onset LN group showed a worse baseline kidney function and more chronic pathological lesions than the early-onset LN group. During a follow-up time of 55 (3, 207) months, 114 (13.1%) deaths occurred, 107 (12.2%) had doubling of creatinine, and 80 (9.1%) developed end-stage kidney disease. The 5- and 10-year survival rates of the late-onset LN group were 67.6 and 50.5%, respectively, which were much worse than those of the early-onset LN group (89.8 and 84.6%, respectively). However, no significant difference was found on kidney survival (log-rank chi-square = 3.55, p = 0.06). Cox regression analysis showed that late-onset LN was an independent risk factor for patient survival (hazard ratio = 3.03, 95% CI (1.39, 6.58), p = 0.005). Increased baseline serum creatinine was an independent risk factor for kidney survival of patients with late-onset LN. Conclusions Patients with late-onset LN had milder active lesions but severer chronic lesions in kidney pathology. They have poorer overall outcome but relatively favorable kidney outcome. Trial Registration ClinicalTrials.gov Identifier: NCT03001973, 22 December 2016 retrospectively registered.

Abstract
Background With the ageing population and changes in the indications of diagnostic and protocol biopsies in systemic lupus erythematosus in recent years, an impact on the incidence and presentation of lupus nephritis (LN) is expected. The aim of this study was to analyse the epidemiological changes regarding clinical and histological presentation of LN in kidney biopsies performed from 1994 to 2019 included in the Spanish Registry of Glomerulonephritis. Methods We analysed data from 28 791 kidney biopsies from 130 Spanish hospitals comparing demographic, clinical and histological data. We divided the cohort according to the age of onset of LN into pediatric onset (<18 years), adult onset (18–50 years) and late onset (>50 years). Results The incidence of LN has decreased from 9.6% of all kidney biopsies in the period 1994–2013 to 7% in the last quarter of the observation period (2014–2019) (P < 0.001), despite an increase in the proportion of patients with LN that underwent repeat biopsies (16.6–24%; P < 0.001). The age of onset of LN has increased from 32 ± 14 to 38 ± 14 years (P < 0.001), with an increase in the proportion of late-onset LN (from 13% to 22% of incident LN; P < 0.001). There were no differences in the distribution of histological features at presentation over the study period. Patients with late-onset LN showed fewer gender differences, had lower GFR and presented with less-proliferative forms of LN compared with early-onset LN. Conclusions The frequency of biopsy-proven LN has been decreasing in recent years, despite an increasing number of repeat biopsies. Late-onset LN is increasing, presenting with worse kidney function but fewer proliferative lesions compared with younger-onset LN.

Late-onset versus early-onset systemic lupus: characteristics and outcome in a national multicentre register (RELESSER). Rheumatology (Oxford) 2021; 60:1793-1803.

Abstract
OBJECTIVE The aim of the present study was to describe the demographic, clinical and immunological characteristics of patients with late-onset (≥50 years) SLE vs patients with early-onset SLE (<50 years). METHODS We performed a cross-sectional retrospective study of 3619 patients from the RELESSER database (National Register of Patients with Systemic Lupus Erythematosus of the Spanish Society of Rheumatology). RESULTS A total of 565 patients (15.6%) were classified as late-onset SLE and 3054 (84.4%) as early-onset SLE. The male-to-female ratio was 5:1. Mean (s.d.) age at diagnosis in the late-onset group was 57.4 (10.4) years. At diagnosis, patients with late-onset SLE had more comorbid conditions than patients with early-onset SLE; the most frequent was cardiovascular disease (P <0.005). Furthermore, diagnostic delay was longer in patients with late-onset SLE [45.3 (3.1) vs 28.1 (1.0); P <0.001]. Almost all patients with late-onset SLE (98.7%) were Caucasian. Compared with early-onset SLE and after adjustment for time since diagnosis, patients with late-onset SLE more frequently had serositis, major depression, thrombotic events, cardiac involvement and positive lupus anticoagulant values. They were also less frequently prescribed immunosuppressive agents. Mortality was greater in late-onset SLE (14.3% vs 4.7%; P <0.001). CONCLUSION Late-onset SLE is insidious, with unusual clinical manifestations that can lead to diagnostic errors. Clinical course is generally indolent. Compared with early-onset disease, activity is generally reduced and immunosuppressants are less commonly used. Long-term prospective studies are necessary to determine whether the causes of death are associated with clinical course or with age-associated comorbidities in this population.

Analysis of clinical and laboratory characteristics and pathology of lupus nephritis-based on 710 renal biopsies in China. Clin Rheumatol 2020; 39:3353-3363. [PMID: 32435895 DOI: 10.1007/s10067-020-05115-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 04/04/2020] [Accepted: 04/16/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVES This study aimed to analyse the clinical and laboratory characteristics of different pathologic classifications of lupus nephritis (LN) patients in terms of age at systemic lupus erythematosus (SLE) diagnosis and nephritis onset. METHOD Clinical, laboratory, and pathological data of 710 LN patients diagnosed by renal biopsy at our institution between 2000 and 2018 were retrospectively analysed. Patients were divided into the different pathological classification groups; childhood-, adult- and elderly-onset SLE groups and early- and late-onset LN groups. RESULTS Class IV occurred most frequently and had the lowest complement C3 level. There was an obvious increase in active index in class IV and class V + IV. Patients with class VI showed some clinical characteristics similar to end-stage renal disease. Patients with proliferative nephritis were younger at SLE diagnosis and had higher blood pressure, higher frequency of proteinuria and urinary erythrocyte and lower haemoglobin and complement C3. Pathologic classification between childhood-, adult- and elderly-onset SLE patients or between early- and late-onset LN patients was not significantly different. Elderly-onset SLE patients had the highest chronic index (CI), IgA, IgG and Sjögren's syndrome A antibodies and Sjögren's syndrome B antibodies rates, whereas late-onset LN patients showed significantly higher CI, haemoglobin, complement C3 and C4 but lower uric acid, IgM and IgG. CONCLUSIONS LN patients present with different clinical and laboratory characteristics according to pathological classification, age at SLE diagnosis and nephritis onset. These results might be valuable for estimating the pathology and guiding treatment and prognosis. Key Points • Patients with proliferative nephritis have more severe immune disorders, worse renal function and stronger inflammatory state. • The elderly-onset SLE patients showed a poorer condition. • The late-onset LN patients might have a more stable status.

Abstract
Lupus nephritis (LN) affects up to 50% of patients with Systemic Lupus Erythematosus (SLE) and is associated with a worse prognosis. LN usually develops within the first 5 years of the onset of the disease. We report three patients with very delayed LN (DLN) diagnosed after 15 or more years after SLE diagnosis. The three patients were non-Caucasian women with adolescent or adult-onset SLE. Each had antinuclear, anti-dsDNA and anti-Ro antibodies. Hydroxychloroquine was prescribed for each. Their disease courses were characterised by sporadic non-renal flares controlled by steroids and, in two cases, by one cycle of rituximab. Unexpectedly, they developed proteinuria, haematuria and lowering of estimated glomerular filtration rate with clinical signs of renal disease. LN was confirmed by renal biopsy. Reviewing them, each showed serological signs of increasing disease activity (rising levels of anti-dsDNA antibodies and fall in C3) that predated clinical or laboratory signs of LN by 1–3 years. Reviewing the literature, we found a lack of knowledge about DLN starting more than 15 years after SLE diagnosis. With the increasing life expectancy of patients with SLE it is likely that more cases of very DLN will emerge.

Abstract
OBJECTIVES Phenotypes differ between late- and early-onset systemic lupus erythematosus (SLE). Prior studies suggested that there may be more pulmonary disease among late-onset patients. Our objective was to perform a systematic review and meta-analysis to evaluate the differences in pulmonary manifestations in late- versus early-onset SLE. METHODS We searched the literature using PubMed, CINAHL, Web of Science, Cochrane Library, and EMBASE. We excluded studies that did not include American College of Rheumatology SLE classification criteria, an early-onset SLE comparison group, or those that defined late-onset SLE as <50 years of age. We rated study quality using the Newcastle-Ottawa Quality Scale. We used Forest plots to compare odds ratios (95% confidence intervals) of pulmonary manifestations by age. Study heterogeneity was assessed using I2. RESULTS Thirty-nine studies, representing 10,963 early-onset and 1656 late-onset patients with SLE, met eligibility criteria. The odds of developing several pulmonary manifestations were higher in the late-onset group. Interstitial lung disease (ILD) was nearly three times more common (OR = 2.56 (1.27, 5.16)). Pleuritis (OR = 1.53 (1.19, 1.96)) and serositis (OR = 1.31 (1.05, 1.65)) were also more common in the late-onset group. The mean Newcastle-Ottawa Quality Scale score for study quality was moderate (6.3 ± 0.7, scale 0-9). CONCLUSIONS Pulmonary manifestations of SLE were more common in late-onset SLE patients compared to their younger peers, in particular ILD and serositis. Age-related changes of the immune system, tobacco exposure, race, and possible overlap with Sjögren's syndrome should be examined in future studies.

Abstract
OBJECTIVES Although systemic lupus erythematosus (SLE) most commonly occurs in reproductive-age women, some are diagnosed after the age of 50. Recognizing that greater than one-third of SLE criteria are cutaneous, we undertook a systematic review and meta-analysis to evaluate differences in cutaneous manifestations in early- and late-onset SLE patients. METHODS We searched the literature using PubMed, CINAHL, Web of Science, and Cochrane Library. We excluded studies that did not include ACR SLE classification criteria, early-onset controls, that defined late-onset SLE as <50 years of age, or were not written in English. Two authors rated study quality using the Newcastle Ottawa Quality Scale. We used Forest plots to compare odds ratios (95% CI) of cutaneous manifestations by age. Study heterogeneity was assessed using I(2). RESULTS Overall, 35 studies, representing 11,189 early-onset and 1727 late-onset patients with SLE, met eligibility criteria. The female:male ratio was lower in the late-onset group (5:1 versus 8:1). Most cutaneous manifestations were less prevalent in the late-onset group. In particular, malar rash [OR = 0.43 (0.35, 0.52)], photosensitivity [OR = 0.72 (0.59, 0.88)], and livedo reticularis [OR = 0.33 (0.17, 0.64)] were less common in late-onset patients. In contrast, sicca symptoms were more common [OR = 2.45 (1.91, 3.14)]. The mean Newcastle Ottawa Quality Scale score was 6.3 ± 0.5 (scale: 0-9) with high inter-rater reliability for the score (0.96). CONCLUSIONS Overall, cutaneous manifestations are less common in late-onset SLE patients, except sicca symptoms. Future studies should investigate etiologies for this phenomenon including roles of immune senescence, environment, gender, and immunogenetics.

Abstract
To further investigate into the epidaemiology of systemic lupus erythematosus (SLE) in Southern Europe, we have assessed the incidence, clinical spectrum and survival of patients diagnosed with late-onset SLE (age ≥ 50 years) according to the 1982 American College of Rheumatology (ACR) classification criteria at the single hospital for a well-defined population of Lugo, Northwestern (NW) Spain. Between January 1987 and December 2006, 51 (39.3%) of the 150 patients diagnosed as having SLE fulfilled definitions for late-onset SLE. The predominance of women among late-onset SLE (4:1) was reduced when compared with that observed in early-onset SLE (7:1). However, the incidence of late-onset SLE was significantly higher in women (4.2 [95% confidence interval (CI): 3.1–5.6] per 100,000 population) than in men (1.3 [95% CI: 0.6–2.2] per 100,000 population) ( p < 0.001). As observed in early-onset SLE, the most frequent clinical manifestation in patients with late-onset SLE was arthritis (71.2%). Renal disease was less common in late-onset SLE (13.5%) than in early-onset SLE (26.4%); p = 0.07). In contrast, secondary Sjögren syndrome was more commonly found in the older age-group (27.1% versus 12.1%; p = 0.03). A non-significantly increased incidence of serositis was also observed in late-onset SLE patients (33.9% versus 22.0%; p = 0.13). Hypocomplementaemia (72.9% versus 91.2%) and positive results for anti-DNA and anti-Sm (49.2% and 6.8% versus 68.1% and 23.1, respectively) were significantly less common in late-onset SLE patients than in early-onset SLE. The probability of survival was reduced in late-onset SLE ( p < 0.001). With respect to this, the 10-year and 15-year survival probability were 74.9 % and 63.3% in the late-onset SLE group and 96.3% and 91.0% in patients with early-onset SLE, respectively. In conclusion, our results confirm that in NW Spain SLE is not uncommon in individuals 50 years and older. In keeping with earlier studies, late-onset SLE patients from NW Spain have some clinical and laboratory differences with respect to those individuals with early-onset SLE. Our data support the claim of a reduced probability of survival in the older age-group of SLE patients.
