Objectives
This paper aims to assess in a retrospective fashion the clinical and laboratory features, severity and outcome of juvenile systemic lupus erythematosus (jSLE) from a referral center in ...Turkey.
Methods
We have included all jSLE patients (n = 92) diagnosed according to the revised American College of Rheumatology 1997 criteria between January 2004 and January 2017.
Results
The most prevalent clinical feature in our cohort was mucocutaneous manifestations (97.8%), followed by constitutional (81.5%), hematological (59.8%) and musculoskeletal manifestations (56.5%). Renal involvement was observed in 38% (n = 35) of the patients, whereas biopsy-proven lupus nephritis was detected in 29.3% (n = 27) of the cohort. Neurologic involvement was seen in 15 (16.3%) individuals. Among the patients positive for anticardiolipin IgM and/or IgG (n = 11, 12%), only three developed antiphospholipid antibody syndrome. The mean SLEDAI-2K scores at disease onset (10.5 ± 4.8) showed a substantial decrease at last visit (4.3 ± 4.6). One-quarter of the patients (26.1%, n = 24) had damage according to the PedSDI criteria with a mean score of 0.45 ± 1.0 (range 0–7). When the PedSDI damage items were evaluated individually, growth failure was the most frequent damage criterion (n = 6), followed by seizure (n = 5). Two patients died during the designated study period of end-stage renal disease. The five-year and 10-year survival rate of our cohort was 100% and 94.4%, respectively.
Conclusions
Given the lower frequency of nephritis and central nervous system disease and lower basal disease activity and damage scores, we could conclude that children with jSLE in Turkey have a more favorable course compared to Asian and African American children, as expected from Caucasian ethnicity.

Systemic sclerosis (SSc) represents extremely rare disease with majority of data coming from adults. Studies comparing juvenile- (jSSc) and adult-onset (aSSc) patients are limited. We aimed to ...compare clinical features, treatment modalities and survival rates of jSSc and aSSc patients.
A retrospective study among pediatric and adult Scl patients has been performed. Demographic characteristics, clinical features, autoantibody profiles, and treatment data were retrieved from the databases. Survival analysis was done using Kaplan-Meier plot and factors associated with mortality were identified with multiple regression analysis.
A total of 158 adults and 58 juvenile Scl patients were identified. The mean age at the disease onset was 37±14.7 vs. 8.8 ± 4.1 years, mean age at diagnosis 42±15.2 vs. 10.4 ± 3.8 years and mean follow-up duration was 6.3 ± 4.9 years vs. 6.6 ± 4.9 years for aSSc and jSSc patients, respectively. The frequency of interstitial lung disease (ILD) (50.9% vs 30%, p<0.001) and systemic hypertension (17.9% vs 0, p = 0.009) was significantly higher among aSSc. While aSSc patients had presented mostly with limited cutaneous subset (74.1%), diffuse cutaneous subset was the dominant subset among jSSc (76.7%), (p<0.001). The mortality rate was significantly higher among adults (p = 0.005). The ILD (p = 0.03) and cardiac insufficiency (p = 0.05) were independent risk factors of mortality in both aSSc and jSSc patients.
Juvenile and adult-onset Scl represent rarely seen conditions with different clinical phenotypes. Pediatric patients with LS are more commonly seen by pediatric rheumatologists, in contrary to adults. Diffuse disease subset is the dominant form among juvenile patients, whereas limited form is the main disease subset among adults. On the other hand, juvenile-onset patients have a better survival than those with adult-onset.

Objectives
Childhood-onset systemic lupus erythematosus (cSLE) is a multisystemic autoimmune disease characterized by inflammatory organ damage by means of vasculitis. Pentraxin-3 (PTX3) is expressed ...locally at the sites of inflammatory processes, predominantly from endothelial cells. In adult studies, PTX3 has shown to be an indicator of active vasculitis both in large-vessel and small-vessel vasculitides, as well as in SLE. Moreover, in SLE it has found to be correlated with disease activity, and with some of the clinical manifestations and laboratory parameters. We aimed to ascertain if PTX3 might be a significant mediator in cSLE and if it might indicate active vasculitis during the course of the disease.
Methods
Serum PTX3 levels were measured in 76 patients with cSLE and 41 healthy subjects. We have investigated its relation with disease activity, damage, clinical features, laboratory parameters and medications.
Results
Serum levels of PTX3 were found to be increased in cSLE compared to healthy controls (mean ± SD; 10.6 ± 8.2 ng/mL vs 2.7 ± 1.3 ng/mL, p < 0.001). PTX3 concentrations were also in correlation with SLEDAI-2K (r = 0.57, p < 0.001). When viewed from the clinical perspective, serum PTX3 levels were significantly higher only in patients with active vasculitis (p < 0.001), Raynaud phenomenon (p = 0.006) and mucocutaneous manifestations (p < 0.001). However, an association between PTX3 and age, age at disease onset, disease duration, complement levels, PedSDI score (pediatric version of the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), ESR, CRP, procalcitonin levels, anti-ds DNA antibody, anticardiolipin antibodies was not detected.
Conclusions
Patients with cSLE have increased levels of serum PTX3 compared to healthy controls. Thus, serum PTX-3 level might be a significant mediator in cSLE. Apart from these, the results support that PTX3 reflects active cutaneous vasculitis in cSLE and correlates with disease activity.

Objectives: Vaccination of systemic lupus erythematosus patients with non-live vaccines may decrease vaccine-preventable infections and mortalities. In the present study, we aimed to compare the ...immunogenicity and safety of inactivated hepatitis A vaccination in childhood-onset systemic lupus erythematosus and healthy subjects. Methods: A total of 30 childhood-onset systemic lupus erythematosus and 39 healthy participants who were seronegative for hepatitis A received two doses of the hepatitis A vaccine in a 0- and 6-month schedule. Hepatitis A virus (HAV) IgG antibodies were measured before vaccination and 7 months after the vaccination. Results: Although anti-HAV IgG antibody titers after vaccination were found to be somewhat lower in children with systemic lupus erythematosus than that of the healthy subjects (p < 0.05), the difference in seroconversion rate was insignificant between childhood-onset systemic lupus erythematosus patients (n = 24/30, 80%) and healthy controls (n = 33/39, 84.6%). There was no increase in median Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K scores and anti-ds DNA levels after the vaccination procedure. Seroconversion rates in childhood-onset systemic lupus erythematosus patients were not affected by medication, high disease activity (SLEDAI-2K >6) and anti-ds DNA positivity. None of the patients experienced any flare or adverse reaction throughout the study. Conclusions: According to these results, we conclude that inactivated hepatitis A vaccine is safe and well tolerated in childhood-onset systemic lupus erythematosus patients, with no adverse events or increase in activity. Immunogenicity to the hepatitis A vaccine was adequate, with a seropositivity rate of 80%.
