COVID-19 in children and young adults with kidney disease: risk factors, clinical features and serological response

Background:ANCA-associated systemic vasculitis (AAV) is characterized by a high incidence of complications and high mortality. The most significant complications during the first 3 years of the disease are infectious and cardiovascular. Development of chronic kidney disease also impairs the prognosis of AAV. Refractory to induction therapy can significantly increase the severity of organ lesions in patients with AAV.Objectives:The aim of this study was to determine risk factors for complications and refractory course in patients with AAV.Methods:Patients with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA) were observed during the first 3 years of the disease and included in this study between 2010 and 2018. Most common infectious complications requiring inpatient treatment were pneumonia, mycosis, sepsis, purulent arthritis, purulent otitis media. Cardiovascular complications included pulmonary thromboembolism, myocardial infarction, ischemic stroke, venous thrombosis.Results:In total 209 (165 [79%] female and mean age 51.8 ± 13.2 years) AAV patients (94 GPA; 46 MPA; and 69 EGPA) were included in the analysis. Risk factors for infectious complications were BVAS level at the beginning of induction therapy > 25 (OR – 2.92, 95% CI (1.53;5.45) p<0.001), usage of prednisone in doses more than 60 mg / day at the induction of remission (OR – 2.76, 95% CI (1.45;5.29) p=0.003), usage of prednisone in doses ≥ 10 mg / day after 6 months of induction therapy (OR – 2.60, 95% CI (1.38;4.93) p=0.003), ANCA-PR3 positivity (OR – 2.25, 95% CI (1.13;4.46) p=0.017) and presence of diabetes mellitus in the AAV onset (OR – 1.77, 95% CI (1.14;3.45) p=0.038). Patients with AAV had following risk factors for cardiovascular complications: male (OR – 2.28, 95% CI (1.33;3.88) p=0.002), BVAS level > 25 (OR – 2.1, 95% CI (1.11;3.16) p=0.008) and presence of coronary artery disease in the AAV onset (OR – 2.2, 95% CI (1.18;4.10) p=0.015). ANCA positivity (OR – 5.62, 95% CI (2.1;14.9) p<0.001), presence of rapidly progressive glomerulonephritis in the first 3 months from onset AAV (OR – 5.02, 95% CI (3.42;7.35) p<0.001) and over 60 years of age (OR – 2.17, 95% CI (1.38;3.44) p=0.001) were risk factors of development of chronic kidney disease. Risk factors for refractory to induction therapy in patients with AAV were ANCA-PR3 positivity (OR – 3.13, 95% CI (1.63;6.02) p<0.001), BVAS level > 25 (OR – 2.63, 95% CI (1.74;4.34) p<0.001), initiation of therapy after 4 months from the onset of clinical manifestations (OR – 2.17, 95% CI (1.26;3.91) p=0.005). We additionally defined that identification of pathological phenotypes of alpha-1-antitrypsin was risk factors for refractory course in patients with GPA manifestations (OR – 2.66, 95% CI (1.12;6.33) p=0.048).Conclusion:Our study has shown that high disease activity, ANCA positivity and comorbid pathology increase risk of serious complications. Early administration of immunosuppressive therapy, adequate steroid dosing and use of risk factors for complications and refractory course in clinical practice can significantly improve the prognosis of AAV.Disclosure of Interests:None declared

Behavioral Weight Loss Intervention

Introduction: Few studies have examined behavioral weight loss interventions with respect to change in cardiovascular disease risk factors in young adults (aged 18 to 35 years). Hypothesis: We tested the hypothesis that a 6 month behavioral weight loss intervention resulted in significant improvements in selective cardiovascular disease risk factors in young adults. Methods: Data are presented as median [25 th , 75 th percentiles]. 470 participants (age: 30.9 [27.8, 33.7] years); BMI: 31.2 [28.4, 34.3] kg/m 2 ) were enrolled in a 6 month behavioral weight loss intervention that included weekly group sessions and prescribed an energy restricted diet and moderate-to-vigorous physical activity. Assessments included weight using a standardized protocol, resting blood pressure, and fasting lipids, glucose, and insulin. Statistical significance of change was according to tests of symmetry or the Wilcoxon matched pairs signed ranks test. Results: The primary outcome (weight) was available for 424 of the 470 participants (90.2%). Weight significantly decreased (-7.8 kg [-12.2, -3.7]) (p<0.0001). Systolic (-4.0 mmHg [-8.5, 0.5] and diastolic blood pressure (-3.0 mmHg [-6.5, 1.0]) decreased (p<0.0001). Total cholesterol (-13 mg/dl [-28.0, 2.0]), LDL cholesterol (-9.5 mg/dl [-21.7, 2.0]), triglycerides (-8.5 mg/dl [-44.0, 9.0]), glucose (-4.0 mg/dl [-8.0, 1.0]), and insulin (-2.6 mIU/L [-5.9, 0.7]) decreased (p<0.0001, n=416). There was not a significant change in HDL cholesterol (p=0.72). Conclusions: In conclusion, after 6 months, weight loss was observed in young adults assigned to this behavioral intervention that focused on physical activity and diet modification. They tended to also have improved cardiovascular disease risk factors. This may demonstrate an approach to reducing cardiovascular disease risk in young adults.

Increased Risk

Background: Chronic Kidney Disease (CKD) is an important public health issue and is associated with an increased risk of cardiovascular disease. Risk factors for CKD are well established, but most are typically assessed at or near the time of CKD diagnosis. Our hypothesis was that risk factors for CKD are present earlier in the course of the disease. We compared the prevalence of risk factors between CKD cases and controls at time points up to 30 years prior to CKD diagnosis. Methods: Participants were drawn from the Framingham Heart Study Offspring cohort. CKD was defined as an estimated glomerular filtration rate of ≤60ml/min/1.73m2. Incident CKD cases occurring at examination cycles 6, 7, and 8 were age- and sex-matched 1:2 to controls. Risk factors including systolic blood pressure (SBP), hypertension, lipids, diabetes, smoking status, body mass index (BMI) and dipstick proteinuria were measured at the time of CKD diagnosis and 10, 20 and 30 years prior. Logistic regression models, adjusted for age, sex, and time period, were constructed to compare risk factor profiles at each time point between cases and controls Results: During follow-up, 441 new cases of CKD were identified and these were matched to 882 controls (mean age 69.2 years, 52.4% women). Up to 30 years prior to CKD diagnosis, those who ultimately developed CKD were more likely to have hypertension (OR 1.74, CI 1.21-2.49), be obese (OR 1.74, CI 1.15-2.63) and have higher triglycerides (OR 1.43, CI 1.12-1.84, p=0.005 per 1 standard deviation increase). Each 10mmHg increase in SBP was associated with an OR of 1.22 for future CKD (95% CI 1.10-1.35) Additionally, cases were more likely to have diabetes (OR 2.90, CI 1.59-5.29) and be on antihypertensive therapy (OR 1.65, CI 1.14-2.40, p=0.009) up to 20 years prior to diagnosis. Increasing HDLc was associated with a lower risk of CKD (OR 0.84, CI 0.81-0.97 per 10mg/dl). Conclusions: As many as 30 years prior to diagnosis, risk factors for CKD are identifiable. In particular, modifiable risk factors such as obesity, hypertension and dyslipidemia are present early in the course of the disease. These findings demonstrate the importance of early identification of risk factors in patients at risk of CKD through a life-course approach.

Disabled Patients

Purpose. Adjunctive zonisamide therapy was demonstrated to be beneficial for multiple-disabled patients with refractory childhood-onset epilepsy. Zonisamide is well tolerated, but urolithiasis and calcium sludge in the bladder were sometimes described in patients treated with antiepileptic drug polytherapy including zonisamide. In previous studies, alkaline urine and crystalluria were shown to be risk factors for urolithiasis. Therefore, the effects of zonisamide addition and withdrawal on the urinary pH and crystalluria were investigated in patients treated with antiepileptic drug polytherapy to clarify the cause of urolithiasis induced by zonisamide. Methods. The urinary pH and the degree of crystalluria were retrospectively studied in epilepsy patients one month after the addition or withdrawal of zonisamide as part of their antiepileptic drug treatment regimen over the previous three years. Results. A total of 27 zonisamide-on patients and 16 zonisamide-off patients were enrolled in the study. The urinary pH did not change after the addition or withdrawal of zonisamide. However, the degree of crystalluria significantly increased after the addition () of zonisamide and decreased after its withdrawal (). Conclusions. Zonisamide induces crystalluria without alkalinization of the urine. Crystalluria should be carefully monitored in patients treated with zonisamide to prevent urolithiasis.

Tufted angioma is an acquired vascular proliferation with specific histological characteristics. The most common clinical features are erythematous macules. It occurs predominantly in children and young adults, especially in the chest and neck. We report the case of a male patient, 12 years old, with an increased right ear auricle associated with erythematous macules and increased local temperature, referred with a diagnosis of lepromatous leprosy; however, this diagnosis was questioned. Histopathology was consistent with tufted angioma.
