Onset Systemic Lupus Erythematosus

Systemic Lupus Erythematosus being a chronic autoimmune multisystem inflammatory disease, affects predominantly women of reproductive age group. Childhood – Onset Systemic Lupus Erythematosus is a rare disease with an incidence of 10% - 20%. Positive direct Coombs test in the absence of hemolytic anemia indicates high disease activity and severe renal damage. Herein we report a case of 11-year-old female child diagnosed as Systemic Lupus Erythematosus with positive direct Coombs test in absence of hemolytic anemia which is very rare.

Background:Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with a significant genetic predisposition. Recent studies have identified STAT4 (signal transducers and transcription activators 4) as a susceptibility gene for SLE.Objectives:To investigate the hypothesis of the association of STAT4 rs7574865 G/T polymorphism with the predisposition to SLE in children and its relationship with some of SLE manifestations.Methods:The case-control pilot study included 143 children (39 with SLE and 103 healthy unrelated volunteers as a control group). Diagnosis of SLE was based on 2012 SLICC criteria. STAT4 rs7574865 G/T polymorphism was investigated using allele-specific real-time polymerase chain reaction (RT-PCR).Results:The group of pts with SLE consisted of 29 girls and 10 boys, with an average age of 11.8±3.7 years (from 3 to 17 years) and an average disease duration of 4.1±2.4 years. 79.5% pts had acute cutaneous lupus at the onset, 46.1% - nonscarring alopecia, 71.8% - arthritis, 23.1% - oral and nasal ulcers, 23.1% - serositis, 43.6% - renal involvement, 35.9% –neuropsychiatric disorders. Leucopenia/lymphopenia was found in 71.8% of pts, thrombocytopenia – in 23,1%. ANA were detected in 100% pts, anti-dsDNA – in 79.5%, anti-Sm – in 31.6%, antiphospholipid antibodies - in 7,3%, hypocomplementemia – in 61.5%, positive direct Coombs test – in 35.9 %. Macrophage activation syndrome at the onset was documented in 15.4 % of pts. The distribution of rs7574865 genotypes in the control group showed no significant deviations from the Hardy-Weinberg equilibrium. The distribution of genotype frequencies among pts had statistically significant differences compared to the control (χ2=12.95, p=0.0015): GG-30.8% and 63.1% (p=0.001), GT-56.4% and 33.0% (p=0.018), TT-12.8% and 3.9% (p=0.114), GT+TT - 69.2% and 36.9% (p=0.0005). The frequency of the mutant STAT 4 allele T (polymorphism), was significantly higher in the SLE group than in the control group (41% and 20.4%, respectively; p=0.0007). We identified an association of the T allele with some clinical, laboratory, and immunological disorders in SLE: arthritis (OR 3.9, p=0.0002), acute cutaneous lupus (OR 2.47, p=0.003), nonscarring alopecia (OR 3.12, p=0.002), renal involvement (OR 2.42, p=0.022), leucopenia (OR 2.72, p=0.003), thrombocytopenia (OR 4.88, p=0.002), anti-dsDNA (OR 2.82, p=0.0006), hypocomplementemia (OR 2.34, p=0.012), positive direct Coombs test (OR 3.38, p=0.002).Conclusion:Our pilot study confirmed that the STAT4 rs7574865 G/T polymorphism was associated with the risk of SLE in children and some of SLE manifestations.Disclosure of Interests:None declared

Objective.To compare clinical features and mortality between childhood-onset systemic lupus erythematosus (cSLE) and adult-onset SLE (aSLE) in a prospective single-center cohort.Methods.A total of 1112 patients with SLE (133 cSLE and 979 aSLE) were enrolled and followed from 1998 to 2012. The 2 groups were compared regarding American College of Rheumatology (ACR) classification criteria for SLE, autoantibodies, disease activity measured by the Adjusted Mean SLE Disease Activity Index (AMS), damage measured by the Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI), and medication. The standardized mortality ratio (SMR) was calculated. Predictors of mortality in SLE were evaluated using Cox proportional hazard models.Results.After a mean followup of 7.6 years, patients with cSLE had a higher number of cumulative ACR criteria and a higher AMS (p < 0.001 each), but there was no difference in SDI (p = 0.797). Immunosuppressants were used more frequently by patients with cSLE (p < 0.001). The SMR of cSLE was 18.8 (95% CI 8.6–35.6), significantly higher than that of aSLE (2.9, 95% CI 2.1–3.9). We found cSLE to be an independent predictor of mortality (HR 3.6, p = 0.008). Moreover, presence of hemolytic anemia (7.2, p = 0.034) and antiphospholipid antibody (aPL; 3.8, p = 0.041) increased the magnitude of risk of early mortality more in the patients with cSLE than in those with aSLE.Conclusion.The clinical course of cSLE as measured by number of clinical manifestations and disease activity is worse than that of aSLE. Also, cSLE patients with hemolytic anemia and aPL are at greater risk of death than patients with aSLE who have those features.

We determined the clinical utility of the direct Coombs’ test in the absence of hemolytic anemia as an indicator of disease activity and therapeutic response in systemic lupus erythematosus (SLE). SLE patients without hemolytic anemia who visited our hospital from January 2016 to November 2016 were retrospectively evaluated with a direct Coombs’ test. Clinical features, including SLE disease activity index (SLEDAI), treatment and laboratory findings were analyzed. For patients with lupus nephritis, we additionally evaluated the cumulative complete renal response rate over one year after induction therapy. Among 182 patients evaluated, 10 (5.8%) patients had a positive direct Coombs’ test in the absence of hemolytic anemia. They had a higher SLEDAI ( p < 0.01), higher circulating immune complex levels ( p = 0.01), higher anti-DNA titers ( p < 0.01) and a lower complete renal response rate ( p = 0.03) compared with those who were negative. Multivariate analysis indicated that SLEDAI was an independent factor correlated with the direct Coombs’ test without hemolytic anemia (odds ratio 2.4, 95% confidence interval 1.66–4.98, p < 0.01). A positive direct Coombs’ test in the absence of hemolytic anemia may therefore represent a useful biomarker for assessing disease activity and therapeutic response.
