Objectives: This study aimed to investigate coronavirus disease 2019 (COVID-19) vaccination rates and factors affecting vaccination in children with rheumatic diseases. Patients and methods: This multicenter cross-sectional survey-based study was conducted between July 2022 and September 2022. Four hundred seventy-four patients (256 females, 218 males; median age: 15 years; interquartile range, 13 to 16 years) were included in the patient group, and 211 healthy children (124 females, 87 males; median age: 15 years; interquartile range, 13 to 16 years) were included in the control group. A questionnaire was administered to the parents face-to-face during routine outpatient visits. Results: Of the patients, 220 were followed up with the diagnosis of autoinflammatory disease, 174 with juvenile idiopathic arthritis, 48 with connective tissue disease, 23 with vasculitis, eight with uveitis, and one with sarcoidosis. In the study group, 256 (54%) patients and 115 (54.5%) healthy children received at least one dose of COVID-19 vaccine. Parents' concern regarding potential side effects of the vaccine was the most common reason for COVID-19 vaccination hesitancy in both groups. The median patient age, follow-up period, colchicine treatment rates, childhood vaccination and influenza vaccination rates, median parental age, parental vaccination rate, and parental education level were higher in vaccinated patients (p<0.05 for all). In addition, vaccination rates were high in patients who shared their concerns about vaccination with the rheumatology team (p<0.001). Conclusion: Parents' concerns about safety and side effects were found to be the most important factors affecting vaccination success. Identification of the underlying causes of parental vaccine hesitancy will facilitate the development of effective vaccination strategies for potential future outbreaks. [ABSTRACT FROM AUTHOR]

Background: Multisystem inflammatory syndrome in children (MIS‐C) is hyperinflammation following coronavirus disease 2019 (COVID‐19), which affects many organs. The retina and choroid are affected by COVID‐19 through microangiopathy and thrombosis but the literature on MISC‐C is limited. Methods: Thirty children (60 eyes) with MIS‐C (the study group, or SG) and 32 age‐and gender‐matched healthy children (64 eyes) (the control group, or CG) were included in the prospective case–control study. Complete ophthalmological examinations, measurements of the vessel densities of the retinal layers, and flow area of the outer retina and choriocapillaris in both groups were conducted with optical coherence tomography angiography (OCT‐A). Results: The mean age of the SG was 11.9 ± 3.9 and that of the CG was 12.5 ± 4.6 years (p = 0.197). In this study we found that the vessel density of the deep layer of the inner retina was decreased significantly and was reduced in the outer retina of flow area in the SG in comparison with the CG (p < 0.05, for all). However, there was no significant difference between the groups regarding other measurements. Conclusions: In MIS‐C patients, vessel densities in the deep layer of the inner retina and in the flow area of the outer retina decreased significantly. This OCTA‐A finding suggests that MIS‐C is related to endothelial thrombotic condition problems in small branches of the retinal artery. The results of this study support the idea that there is a need for screening of MIS‐C patients for the presence of these microangiopathic and perfusional complications. [ABSTRACT FROM AUTHOR]

Background: This study aimed to investigate the characteristics of patients with preadolescent‐ and adolescent‐onset immunoglobulin A vasculitis (IgAV) and to determine whether age affects IgAV outcomes in adolescents. Methods: Demographic, clinical, and laboratory data of 333 patients diagnosed with IgAV at the Department of Pediatric Rheumatology, University of Health Sciences, Ankara City Hospital, were evaluated retrospectively. The patients were classified into two groups: preadolescents (<10 years) and adolescents (10–19 years). Subgroup analyses were also performed by grouping the adolescent patients into early, middle, and late adolescent groups. Results: Of the 333 patients, 219 (65.8%) and 114 (34.2%) were preadolescents and adolescents. Palpable purpura, renal, joint, and gastrointestinal (GI) tract involvement were detected in 333 (100%), 78 (23.4%), 79 (23.7%), and 124 (37.2%) patients, respectively; testicular involvement was observed in 25 (13.3%) of 187 male patients. The frequency of renal involvement was significantly higher in the adolescent group than in the preadolescent group at the time of diagnosis (p = 0.030). Notably, joint involvement was significantly higher in the adolescent group (p = 0.001). The need for aggressive therapy was significantly higher in the adolescent group than in the preadolescent group (p = 0.003). There was no significant difference in clinical data, demographic characteristics, and laboratory findings between the adolescent subgroups (p > 0.05). Conclusions: Immunoglobulin A vasculitis can occur at any age but the disease prognosis appears to worsen with age. The present study reported that joint involvement, kidney involvement, and the need for more aggressive treatment were higher in the adolescent group than in the preadolescent group.

CYSTINURIA , *KIDNEY stones , *URINARY calculi - Abstract
Objective: Cystinuria is a rare genetic disorder. Many patients suffer from significant recurrent urolithiasis, repeated surgical interventions, and the risk of progressive renal impairment. In the current study, the outcomes of patients with cystine stones were investigated. Material and Methods: A total of Twenty-six cystinuria patients with cystine stones, aged between 3 months and 18 years, in our Pediatric Nephrology Department, were retrospectively analyzed. Results: The mean age of patients at diagnosis was 45.2±45.5 months and 88,5% were male. Sixteen (62%) children had recurrent urinary tract infections. Only 10 (38%) patients showed additional metabolic abnormalities. The urinary pH had significantly increased with treatment and the number of stone recurrence was lower in the patients with urinary pHs ≥ 6.5. There was a significant positive correlation between the last-visit serum creatinine level and the number of surgical interventions. There was no significant correlation between the last-visit eGFR and the number of surgical interventions. On the other hand, eGFR values decreases as the total number of surgical interventions increases. No stone events were observed at the end of the follow-up period in 10 patients (38%) and the stone events per patient-year were 0.36 for all patients. Four patients with low eGFRs at the beginning of the study get normal with treatment after the follow-up period. Conclusion: Cystinuria has significant morbidity if not controlled properly. Despite all treatments, it should be kept in mind that renal impairment may develop in cystine stones with cystinuria and surgical treatment should be planned by considering minimally invasive options.

- Abstract
Thrombotic microangiopathy (TM), especially thrombotic thrombocytopenic purpura (TTP) is described in systemic lupus erythematosus (SLE) as a severe hematological involvement. However hemolytic uremic syndrome (HUS) is seen less frequently in SLE, particularly as an initial presentation. Here we present a 15-year old boy presenting with gross hematuria, decreased urinary output and petechial lesions. He was diagnosed as atypical HUS according to the classical triad of TM, along with observation of hypocomplementemia and negative stool cultures. In addition, his symptoms fulfilled the 2012 revised criteria for the classification of SLE. He was treated with plasma infusions and methylprednisolone/prednisone. At follow up his laboratory findings and general condition improved and no relapse was seen. [ABSTRACT FROM AUTHOR]

- Abstract
Acute tubulointerstitial nephritis (TIN) is a common cause of acute renal impairment, characterized by the infiltration of inflammatory cells in the interstitium of the kidney. We retrospectively reviewed the medical records of 19 acute TIN patients attended to our Pediatric Nephrology department between April 1999 and April 2014. Nineteen patients (7 boys and 12 girls) were evaluated. The median age was 14 years (range 7-19). Five were diagnosed as TIN histopathologically, fourteen patients were diagnosed as clinically. Six patients were treated with steroids, thirteen patients were treated symptomatically. All patients showed a rapid recovery at longest in one month. TIN is a common cause of acute renal impairment. Renal biopsy is recommended for persistent cases. Renal outcome is mostly good with symptomatic treatment but steroids could be preferred in severe nephritis however long-term follow up showed no differences between the treated and non-treated group.

Cytomegalovirus (CMV) infections are mostly seen in immunocompromised patients. However, unusual manifestations or complications of acquired CMV infections in immunocompetent patients are rarely reported. CMV-related hemorrhagic cystitis is extremely rare but should be considered even in immunocompetent patients. We present a case of a 3-year-old immunocompetent boy with intermittent, terminal gross hematuria lasting for 1 month. There was no history of genitourinary trauma or stone disease. Urine analysis revealed hematuria with eumorphic red blood cells and no proteinuria. Urine culture was negative. Ultrasonography showed increased bladder wall thickness and irregularity at inferior of bladder. Cystoscopy revealed hyperemia and edema. Histopathological examination was consistent with CMV infection, viral DNA by polymerase chain reaction in peripheral blood and urine were positive. Clinical, laboratory, and imaging features pointed towards hemorrhagic cystitis due to CMV. He was followed-up with no treatment. After 1 month, repeated investigations showed complete resolution of finding. This is a rare description of an immunocompetent child with CMV-induced cystitis. [ABSTRACT FROM AUTHOR]

Background: atypical hemolytic uremic syndrome (aHUS) occurs due to defective regulation of the alternative complement pathway (ACP) on vascular endothelial cells. Plasma based therapy (PT) was the mainstay of the treatment for aHUS for many years until the introduction of therapies targeting blockage of the complement system. The aim of this study was to evaluate patients with aHUS who had been treated with plasma based therapies alone. Methods: the outcomes of seven genetically confirmed aHUS patients (2 girls, 5 males) were evaluated by means of clinical presentation, response to plasma therapy, course of the disease during the follow-up period and last status. Results: the median age of the patients at admission was 6.7 years (IQR 0.7-7.8). Three patients received plasma exchange therapy and the other four patients were treated with plasma infusions. One patient was lost to follow-up after one year; the median duration of follow-up for other patients was 3.7 years (IQR 2.7-6.5). During the follow up, two patients from our historical records when complement blocking therapies had not been in clinical use yet in Turkey, underwent kidney transplantation. One transplant patient experienced an acute rejection episode without graft loss. The remaining five patients had a glomerular filtration rate of more than 90 ml/min./1.73 m(2) at the last visit. Conclusion: although we had a relatively small patient population, our findings indicate that PT might still be considered in selected patients particularly in countries where complement blocking therapies are difficult to reach due to their unavailability or costs that are not covered by the health care systems., Hacettepe University Scientific Research and Development Office
