Longitudinal disease- and steroid-related damage among adults with childhood-onset systemic lupus erythematosus.

ObjectivesDetermine whether adults with childhood-onset systemic lupus erythematosus (cSLE) are at increased risk for disease- and steroid-related damage as compared to individuals with adult-onset SLE (aSLE), and whether they continue to accumulate disease damage in adulthood.MethodsData derive from the 2007-2015 cycles of the Lupus Outcomes Study, a longitudinal cohort of adults with confirmed SLE. The Brief Index of Lupus Damage (BILD), a validated, patient-reported measure, was used to assess SLE-associated damage. Participants with baseline BILD were included (N = 1035). Diagnosis at age < 18 years was defined as cSLE (N = 113). Outcome variables included BILD score at baseline and follow-up, clinically significant change in BILD score over follow-up period, and presence of steroid-related damage (cataracts, osteoporosis-related fracture, avascular necrosis or diabetes mellitus).ResultsMean time between baseline and follow up BILD assessment was 6.3 ± 1.7 years. In adjusted analyses, participants with cSLE and aSLE had similar levels of disease-related damage, and accumulated damage at similar rates. Participants with cSLE were more likely to report steroid-related damage (OR 1.7, 95% CI 1.1-2.8) in the adjusted analysis as compared to those with aSLE. Likelihood of steroid-related damage increased with disease duration for both groups, but was consistently higher among cSLE participants.ConclusionIn this longitudinal cohort of adults with SLE, participants continued to accumulate damage at similar rates over time, regardless of age at onset or disease duration. Childhood-onset predicted increased risk of steroid-related damage. Aggressive use of steroid-sparing treatment strategies during childhood may be important to prevent steroid-related damage in adulthood

Final adult height of patients with childhood-onset systemic lupus erythematosus: a cross sectional analysis

Abstract Background To compare final height to mid-parental target height among adults with childhood-onset systemic lupus erythematosus (cSLE) versus adult-onset SLE (aSLE), and to evaluate the impact of age at SLE onset on final height. Methods Data derived from the Lupus Outcomes Study, a longitudinal cohort of adults with SLE, was used for this cross-sectional analysis (N = 728). Participants aged 18–63 years with complete height data were included (N = 566) and were classified as cSLE if age at diagnosis was  2 SD below target height. Separate analyses were conducted for females and males to account for differences in timing of the pubertal growth spurt for each sex. Results Participants with cSLE were, on average, 2.4 cm shorter than their target height (95% CI -4, − 0.7). The adjusted odds ratio (OR) for substantially reduced final height was 3.9 (95% CI + 2.0, + 7.2, p < 0.001) as compared to participants with aSLE. Females diagnosed between 11 and 13 years were at greatest risk for substantially reduced final height, with adjusted OR of 11.2 (95% CI + 3.4, + 36.3) as compared to participants with aSLE (p < 0.001). Conclusions cSLE is associated with shorter-than-expected final height. Onset of SLE in the pubertal period, near the time of maximum linear growth, may have a particularly significant impact on final height

Final adult height of patients with childhood-onset systemic lupus erythematosus: a cross sectional analysis.

BACKGROUND:To compare final height to mid-parental target height among adults with childhood-onset systemic lupus erythematosus (cSLE) versus adult-onset SLE (aSLE), and to evaluate the impact of age at SLE onset on final height. METHODS:Data derived from the Lupus Outcomes Study, a longitudinal cohort of adults with SLE, was used for this cross-sectional analysis (N = 728). Participants aged 18-63&nbsp;years with complete height data were included (N&nbsp;= 566) and were classified as cSLE if age at diagnosis was &lt; 18&nbsp;years (N = 72). The Tanner formula was used to calculate mid-parental target height. Multivariate linear regression was used to determine mean difference between final height and target height. Multivariate logistic regression was used to compare odds of substantially reduced final height, defined as &gt; 2 SD below target height. Separate analyses were conducted for females and males to account for differences in timing of the pubertal growth spurt for each sex. RESULTS:Participants with cSLE were, on average, 2.4&nbsp;cm shorter than their target height (95% CI -4, - 0.7). The adjusted odds ratio (OR) for substantially reduced final height was 3.9 (95% CI + 2.0, + 7.2, p &lt; 0.001) as compared to participants with aSLE. Females diagnosed between 11 and 13&nbsp;years were at greatest risk for substantially reduced final height, with adjusted OR of 11.2 (95% CI + 3.4, + 36.3) as compared to participants with aSLE (p &lt; 0.001). CONCLUSIONS:cSLE is associated with shorter-than-expected final height. Onset of SLE in the pubertal period, near the time of maximum linear growth, may have a particularly significant impact on final height

Case Series of Myocarditis Following mRNA COVID Vaccine Compared to Pediatric Multisystem Inflammatory Syndrome: Multicenter Retrospective Study

Introduction: Since the development of COVID-19 vaccines, more than 4.8 billion people have been immunized worldwide. Soon after vaccinations were initiated, reports on cases of myocarditis following the second vaccine dose emerged. This study aimed to report our experience with adolescent and young adults who developed post-COVID-19 vaccine myocarditis and to compare these patients to a cohort of patients who acquired pediatric inflammatory multisystem syndrome (PIMS/PIMS-TS) post-COVID-19 infection. Methods: We collected reported cases of patients who developed myocarditis following COVID-19 vaccination (Pfizer mRNA BNT162b2) from all pediatric rheumatology centers in Israel and compared them to a cohort of patients with PIMS. Results: Nine patients with post-vaccination myocarditis were identified and compared to 78 patients diagnosed with PIMS. All patients with post-vaccination myocarditis were males who developed symptoms following their second dose of the vaccine. Patients with post-vaccination myocarditis had a shorter duration of stay in the hospital (mean 4.4 &plusmn; 1.9 vs. 8.7 &plusmn; 4.7 days) and less myocardial dysfunction (11.1% vs. 61.5%), and all had excellent outcomes as compared to the chronic changes among 9.2% of the patients with PIMS. Conclusion: The clinical course of vaccine-associated myocarditis appears favorable, with resolution of the symptoms in all the patients in our cohort

The characteristics of patients with COVID-19-associated pediatric vasculitis: an international, multicenter study

Objective: COVID-19 associated pediatric vasculitis other than Kawasaki disease (KD)-like vasculitis in multisystem inflammatory syndrome in children (MIS-C) is very rare. We aimed to analyze the characteristics, treatment and outcome in COVID-19-associated pediatric vasculitis (excluding KD-like vasculitis in MIS-C). Methods: The inclusion criteria were as follows: 1) &lt;18 years at vasculitis onset; 2) evidence of vasculitis; 3) evidence of SARS-CoV-2 exposure; 4) ≤3 months between SARS-CoV-2 exposure and vasculitis onset. Patients with MIS-C were excluded. Results: Forty-one patients (median age 8.3 years; M/F=1.3) were included from 14 centers and six countries. The most frequent vasculitis subtype was IgA vasculitis/Henoch Schönlein purpura (IgAV/HSP) (n=30). The median duration between SARS-CoV-2 exposure and vasculitis onset was 13 days. Skin (92.7%) and gastrointestinal (61%) involvements were the most common manifestations of vasculitis. Most patients (68.3%) received corticosteroids; while 14.6% used additional immunosuppressive drugs. Remission was achieved in all. All IgAV/HSP patients had skin manifestations while 18 (60%) and 13 (43.3%) had gastrointestinal system and renal involvement, respectively. When we compared the features of these patients with those of a pre-pandemic pediatric IgAV/HSP cohort (n=159), fever (30% vs. 5%; p&lt;0.001) and renal involvement (43.3% vs. 17.6%; p=0.002) were more common, while recovery without treatment (10% vs. 39%; p=0.002) and complete recovery (86.7% vs. 99.4%; p=0.002) were less frequent among COVID-19-associated IgAV/HSP patients. Conclusion: This is the largest cohort of children with COVID-19 associated vasculitis (excluding MIS-C). Our findings suggest a more severe disease course in COVID-19-associated pediatric IgAV/HSP patients compared to pre-pandemic patients. This article is protected by copyright. All rights reserved
