Vascular Calcification in an Adolescent Treated with Long-Term Peritoneal Dialysis
The reason of high mortality in patients with chronic kidney disease (CKD) is cardiovascular disease and arterial calcification has been accepted as an additive factor on this status. In this report we described vascular and cardiac valvular calcifications in an adolescent on CAPD
Sacroiliitis in Children With Familial Mediterranean Fever
Cakar, Nilgun/0000-0002-1853-0101; Ozcakar, Zeynep/0000-0002-6376-9189WOS: 000459940100003PubMed: 29596210Background/Objective Familial Mediterranean fever (FMF) is an autosomal recessive disease, characterized by recurrent, self-limited attacks of fever with serositis. Various diseases were reported to be associated with FMF. The aim of this study was to investigate the frequency and characteristics of sacroiliitis in children with FMF. Methods Files of FMF patients who had been seen in 2 reference hospitals in Ankara were retrospectively evaluated. Patients with FMF and concomitant sacroiliitis were included to the study. All patients had magnetic resonance imaging evidence of sacroiliitis. Results Among 650 FMF patients, 17 (11 females, 6 males; mean age, 13.32 +/- 4.24 years) (2.6%) of them were found to have sacroiliitis. Familial Mediterranean fever diagnosis was done prior to sacroiliitis diagnosis in 11 patients (65%) and concurrently or afterward in 6 patients (35%). Ten patients had isolated sacroiliitis, and 7 had associated diseases (5 enthesitis-related arthritis, 1 psoriatic arthritis, and 1 ulcerative colitis). Arthritis (59%), arthralgia (77%), leg pain (71%), heel pain (41%), and enthesitis (29%) were common complaints. Sacroiliac tenderness was detected in 77%, and M694V mutation in almost 90% of the patients. All patients received colchicine therapy. Additionally, 14 of them were treated with nonsteroidal anti-inflammatory drugs, 10 were on sulfasalazine treatment, and 7 of them were on biological agents. Conclusions Sacroiliitis can be seen in patients with FMF during childhood, and M694V mutation seems to be a susceptibility factor for its development. Inflammatory low-back pain and leg and heel pain could suggest sacroiliitis

Agbas, Ayse/0000-0002-3658-8622; Ozcakar, Zeynep/0000-0002-6376-9189; Cakar, Nilgun/0000-0002-1853-0101WOS: 000437355600002PubMed: 29533929Background: There are limited data on infants with atypical hemolytic uremic syndrome (aHUS). The aim of this study was to determine the clinical and laboratory features, and to evaluate treatment modalities and outcomes in infants with aHUS. Materials and Methods: Relevant data on patients with onset of aHUS at age <2 years were obtained from the Turkish Pediatric aHUS Registry. Results: Among the 146 patients included in the Registry, 53 (36%) (23 male and 30 female) were enrolled for the study. Age at disease onset was <= 1 year in 29 of the patients. In all, 21 (40%) of the patients developed neurological symptoms. Disease-causing muta tions were noted in 14 (36%) of the 39 patients in which genetic analysis was performed. Plasma therapy was performed in 42 (79%) patients; eculizumab therapy was administered to treat the first episode of aHUS in 33 (62%) patients and in 5 patients as the first- line therapy. In total, 38 (72%) patients received renal replacement therapy (RRT), 3 (6%) died due to acute illness, and 4 (8%) were discharged from hospital with RRT. Follow-up visit data were available for 46 patients and the median duration was 23 months (range 3-129 months). End-stage renal disease developed only in 1 patient. Proteinuria and hypertension persisted in 17 (37%) and 20 patients (44%) respectively. Eculizumab treatment was continued in 25 of the 39 patients during the follow-up period. Conclusion:One-third of the aHUS patients had disease onset during infancy. The prognosis of this life-threatening disease seems to get better with improved treatment modalities. (C) 2018 S.

DNASE1L3 Mutations in Hypocomplementemic Urticarial Vasculitis Syndrome
Objective. Hypocomplementemic urticarial vasculitis syndrome (HUVS) is characterized by recurrent urticaria along with dermal vasculitis, arthritis, and glomerulonephritis. Systemic lupus erythematosus (SLE) develops in >50% of patients with HUVS, although the pathogenesis is unknown. The aim of this study was to identify the causative DNA mutations in 2 families with autosomal-recessive HUVS, in order to reveal the pathogenesis and facilitate the laboratory diagnosis
Application of the new pediatric criteria and Tel Hashomer criteria in heterozygous patients with clinical features of FMF
Recently, a new set of criteria was established for the diagnosis of familial Mediterranean fever (FMF) in childhood. The aim of this study is to validate the new criteria set among heterozygous patients with clinical features of FMF. The study group consisted of FMF patients, who had a mutation at a single allele, who were followed in four pediatric nephrology-rheumatology centers in Turkey. Patients were evaluated by the new criteria set and also by the Tel Hashomer criteria. According to the new criteria, the diagnosis of FMF was established by the presence of two or more of five criteria (fever, abdominal pain, chest pain, arthritis, family history of FMF). The study group consisted of 110 FMF (54 male, 56 female) patients. Majority of the patients had heterozygous pM694V mutation (65%). The sensitivity of the new criteria set and that of the Tel Hashomer criteria in our study group were found to be 93% and 100%, respectively. In conclusion, this study designates that sensitivity of the new criteria set is also high in patients who had a mutation at a single allele

Prevalence of Hypertension in Children with Early-Stage Adpkd
Background and objectives Autosomal dominant polycystic kidney disease is the most common inheritable kidney disease, frequently thought to become symptomatic in adulthood. However, patients with autosomal dominant polycystic kidney disease may develop signs or symptoms during childhood, in particular hypertension. Although ambulatory BP monitoring is the preferred method to diagnose hypertension in pediatrics, data in children with autosomal dominant polycystic kidney disease are limited. Design, setting, participants, & measurements Our retrospective multicenter study was conducted to collect ambulatory BP monitoring recordings from patients with autosomal dominant polycystic kidney disease age 1 cm per kidney and daytime hypertension (odds ratio, 1.70; 95% confidence interval, 1.21 to 2.4; P=0.002), nighttime hypertension (odds ratio, 1.31; 95% confidence interval, 1.05 to 1.63; P=0.02), or 24-hour hypertension (odds ratio, 1.39; 95% confidence interval, 1.08 to 1.81; P=0.01). Kidney length, expressed as SD score, was also significantly associated with nighttime hypertension (odds ratio, 1.23; 95% confidence interval, 1.06 to 1.42; P=0.10). Conclusions These data indicate high prevalence of hypertension in children with autosomal dominant polycystic kidney disease starting at young ages.WoSScopu
Turkish Pediatric Atypical Hemolytic Uremic Syndrome Registry: Initial Analysis Of 146 Patients
Background Atypical hemolytic uremic syndrome (aHUS) is a devastating disease with significant morbidity and mortality. Its genetic heterogeneity impacts its clinical presentation, progress, and outcome, and there is no consensus on its clinical management. Methods To identify the characteristics of aHUS in Turkish children, an industry-independent registry was established for data collection that includes both retrospective and prospective patients. Results In total, 146 patients (62 boys, 84 girls) were enrolled; 53 patients (36.3%) were less than 2 years old at initial presentation. Among the 42 patients (37.1%) whose mutation screening was complete for CFH, CFI, MCP, CFB, C3, DGKE, and CHFR5 genes, underlying genetic abnormalities were uncovered in 34 patients (80.9%). Sixty-one patients (41.7%) had extrarenal involvement. During the acute stage, 33 patients (22.6%) received plasma therapy alone, among them 17 patients (51.5%) required dialysis, and 4 patients (12.1%) were still on dialysis at the time of discharge. In total, 103 patients (70.5%) received eculizumab therapy, 16 of whom (15.5%) received eculizumab as a first-line therapy. Plasma therapy was administered to 84.5% of the patients prior to eculizumab. In this group, renal replacement therapy was administered to 80 patients (77.7%) during the acute period. A total of 3 patients died during the acute stage. A total of 101 patients (77.7%) had a glomerular filtration rate >90 mL/min/1.73 m2 at the 2-year follow-up. Conclusions The Turkish aHUS registry will increase our knowledge of patients with aHUS who have different genetic backgrounds and will enable evaluation of the different treatment options and outcomes.PubMedWoSScopu
