Popis: BackgroundPediatric patients with a diagnosis of rheumatic disease are at increased risk for infectious diseases due to immune dysregulation arising fromthe disease itself, as well as immunoregulatory or immunosuppressive drugs they use. However, there are studies reporting that COVID-19 disease has a moderate course in children with rheumatic disease.ObjectivesThis study aims to determine the seroprevalence of SARS-CoV-2 in children with rheumatic disease during the COVID-19 pandemic, to evaluate the effects of immunosuppressive drugs and biological agents on seroprevalence of COVID.MethodsBetween September 2020 and September 2021, patients aged 2-18 years with a diagnosis of and with a follow-up period of more than 6 months were included in the study. Patients were selected by “simple random sampling” method.Anti-SARS-CoV-2 antibodies (IgG and IgA) against the S1 domain of the SARS-CoV-2 spike protein were investigated with a micro ELISA kit.Results170 patients, 92 (54.1%) girls, with a mean age of 12.16±4.18 years, were included. The median age at diagnosis was 7.59 (IQR 4.33-11.30) years, and the median follow-up time after diagnosis was 3.24 (IQR 1.87-5.99) years. Primary disease distribution was presented on Figure 1. The co-morbid diseases as obesity, hypertension and chronic kidney disease was present in 4.7%, 9.4% and 5.3% of patients, respectively. The distribution of medications was as follows; colchicine 101 patients (59.4%), Disease Modifying Anti-Rheumatism Drugs 49 (28.8%), steroid 25 (14.7%), and biological agents 28 (16.5%).Figure 1.Distribution of patients according to primary rheumatologic diagnosisAnti-SARS-CoV-2 Ig G antibody was positive in 40 (23.5%) of the patients. Demographic characteristics and treatment-related variables were similar between SARS-CoV-2 IgG seropositive and seronegative patients (Table 1).Table 1.Characteristics of patients who are seropositive and seronegative for anti-SARS-CoV-2 Ig GVariableAnti-SARS-CoV-2 IgG negative patients (n=130)Anti-SARS-CoV-2 IgG positive patients (n=40)pAge (years)11.96±4.1912.80±4.140.528Sex (%)Female67 (%72.8)25 (%27.2)0.150Median age at diagnosis (years)7.56±4.038.69±4.750.195Median follow-up time after diagnosis (years)4.39±3.274.11±3.190.891Diagnosis (%) FMF and other autoinflammatory disease62 (%78.5)17 (%21.5)0.166 Juvenile idiopathic arthritis39 (%78.0)11 (%22.0) SLE ve other autoantibody related diseases16 (%80.0)4 (%20.0) Behçet’s disease8 (%66.7)4 (%33.3) Vasculitis5 (%55.6)4 (%44.4)MEFV mutation Homozygous30 (%75.0)10 (%25.0)0.991 Heterozygous33 (%76.7)10 (%23.3) No mutation36 (%75.0)12 (%25.0)Presence of colchicine usageYes76 (%75.2)25 (%24.8)0.396No54 (%78.2)15 (%21.7)Median colchicine dose (mg/day)1.09±0.441.13±0.420.842Presence of DMARD usageYes37 (%75.5)12 (%24.5)0.499No93 (%76.9)28 (%23.1)Presence of steroid usageYes17 (%68.0)8 (%32.0)0.202No113 (%77.9)32 (%22.1)Median steroid dose (mg/day)10.50±8.9114.71±11.950.333Presence of biological agent usageYes21 (%75.0)7(%25.0)0.505No109 (%76.8)33(%23.2)Thirty-eight (22.4%) of the patients had close contact with an individual diagnosed with COVID-19. Thirty two (18.9%) patients underwent PCR testing for SARS-CoV-2; only 4 (2.4%) had positive. Of these 32 patients, 28.1% were positive for IgG. IgG seropositivity was observed in 3 (75.0%) of 4 patients with PCR positivity.ConclusionWe found the SARS-CoV-2 seroprevalence of 23.5% in children with a diagnosis of rheumatic disease. It seems that primary rheumatological diagnosis does not affect COVID seropositivity in children.Disclosure of InterestsNone declared
