Objective: We aimed to evaluate the clinical significance of the “unclassified” blood pressure phenotypes on left ventricular hypertrophy in children. Materials and Methods: All children evaluated with ambulatory blood pressure monitoring in the pediatric nephrology department between October 2018 and January 2021 were included in the study. Prehypertension, normotensive, white coat hypertension, masked hypertension, ambulatory hypertension groups and 2 other groups including increased blood pressure load, normal ambulatory blood pressure measurements, but normal (unclassified group 1) or high (unclassified group 2) office blood pressure measurements were defined according to the American Heart Association 2014 statement. Left ventricular mass index, left ventricular mass index/95 percentile values, and left ventricular hypertrophy ratios were compared between the groups separately to establish the influence of the unclassified cases. Results: A total of 497 children were included. There were 52 cases in normotensive, 47 cases in unclassified group 1, 50 cases in masked hypertension, 79 cases in white coat hypertension, 104 cases in unclassified group 2, and 165 cases in the ambulatory hypertension group. Left ventricular mass index/95 percentile and left ventricular hypertrophy in masked hypertension were significantly higher than normotensive but similar between normotensive and unclassified group 1 groups. Left ventricular hypertrophy was significantly higher in the ambulatory hypertension group compared to white coat hypertension, and similar between white coat hypertension and unclassified group 2 groups. Conclusion: Independent of age, we have found that interpretation of blood pressure load not only has a limited predictable effect on left ventricular hypertrophy but also causes a large group of patients to be unclassified.

Objective: To compare pulse wave analysis (PWA) of obese children with and without metabolic syndrome (MS) with healthy, non-obese children and to evaluate the association between PWA findings and additional risk factors present in children with MS and obesity. Methods: From the obese patients examined between June 2019 and June 2021, 41 patients with MS, 36 obese patients without MS, and 34 healthy non-obese children of similar age and gender were evaluated retrospectively. Anthropometric measurements, biochemical evaluation, 24-hour ambulatory blood pressure (BP) measurement (ABPM), left ventricular mass index (LVMI) and PWA measurements were compared. Results: When the three groups were compared, weight standard deviation score (SDS), height SDS and body mass index SDS were all significantly higher in the MS group (p<0.05). The following measurements were significantly higher in both MS and non-MS obese patients compared to the control group: from ABPM measures, the systolic and mean arterial pressure BP SDSs load; from PWA, the night central systolic BP, 24-hour, day and night pulse pressure values and 24-hour, day and night pulse wave velocity (PWV) rates; and from cardiac evaluations, the LVMI and relative wall thickness measurements (all p<0.05). Furthermore, the 24-hour and daytime central systolic (cSBP) and diastolic BP (cDBP) values were significantly different between the three groups, being the highest in the MS group (p<0.05). Conclusion: Obesity causes higher office, ambulatory and central BP, PWV and LVMI. However our results suggest that additional risk factors associated with MS do not contribute to these parameters, except for 24-hour and daytime cSBP and cDBP values. [ABSTRACT FROM AUTHOR]

Background: Ventricular repolarization (VR) increases the risk of sudden cardiac death due to ventricular arrhythmia. We aimed to evaluate the blood pressure (BP) parameters affecting VR in obese children. Methods: Obese (BMI ≥ 95p) and healthy children ≥ 120 cm between January 2017 and June 2019 were included. Demographic and laboratory data, peripheral and central BPs evaluated by a device capable of ambulatory blood pressure monitoring (ABPM), and pulse wave analysis were assessed. Electrocardiographic ventricular repolarization indices, left ventricular mass index (LVMI), and relative wall thickness (RWT) were calculated. Results: A total of 52 obese and 41 control patients were included. Uric acid, triglyceride, total cholesterol, LDL, and ALT values, systolic and diastolic office BPs, 24-h, daytime and nighttime systolic and mean arterial BPs, daytime diastolic BP SDS levels, daytime and nighttime systolic loads, daytime diastolic load, 24-h, daytime and nighttime central systolic and diastolic BPs, and pulse wave velocity values were significantly higher, whereas 24-h, daytime and nighttime AIx@75 were similar between the groups. fT4 levels of obese cases were significantly lower. QTcd and Tp-ed were higher in obese patients. Although RWT was higher in obese cases, LVMI values and cardiac geometry classifications were similar. The independent factors affecting VR in obese cases were younger age and higher diastolic load at night (B = − 2.83, p = 0.010; B = 0.257, p = 0.007, respectively). Conclusion: Obese patients have higher peripheral and central BP, arterial stiffness, and higher VR indices that develop before an increase in LVMI. It would be useful to prevent obesity from an early age and follow up nighttime diastolic load to control VR associated sudden cardiac death in obese children. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the effects of non-E. coli or extended-spectrum β-lactamase–positive (ESBL-positive) microorganism growth in the first febrile urinary tract infection (UTI) of infants on laboratory findings or renal parenchymal damage presenting the severity of inflammation, anatomic abnormalities defined by imaging studies, and recurrent UTIs in the follow-up period. Methods: The data of patients aged between 2 and 24 mo and followed up for at least 6 mo with febrile UTI guideline of the authors' pediatric-nephrology clinic, were retrospectively analyzed. Ultrasonography was performed in all the cases at the time of UTI and dimercaptosuccinic-acid (DMSA) at least 4 mo after the infection. Voiding cystourethrography (VCUG) was performed only if ultrasonography findings were abnormal, the uptake deformity was detected in DMSA scan, or the patients experienced recurrent UTIs. The patients were grouped concerning E. coli or non-E. coli and ESBL-PB or non-ESBL-BP growth in the urine cultures. Results: There were 277 infants followed up for 28.55 ± 15.24 (6–86) mo. The causative microorganisms were non-E. coli in 73 (26.4%) and ESBL-PB in 58 (20.9%) cases. CRP values, pyuria, and leukocyte-esterase positivity were significantly higher in UTIs caused by E. coli compared to non-E. coli bacteria. All clinical and laboratory findings were similar between the ESBL-PB and non-ESBL groups, but abnormal ultrasonography findings were more common in non-E. coli group. Conclusion: E. coli causes more severe inflammation, but non-E. coli infections are more frequently associated with ultrasound abnormalities. However, ESBL production did not affect either laboratory or radiological findings in the present cohort. [ABSTRACT FROM AUTHOR]

Aim: The presence and clinical importance of vesicoureteric reflux in patients with a double collecting system are being questioned. Therefore, the role of voiding cystourethrography in the management of patients with ureterocele is unclear. This study aimed to evaluate patients with a ureterocele in terms of urinary tract infection (UTI) and vesicoureteral reflux (VUR). Material Methods: The cases who were admitted to the Pediatric Nephrology Clinic of Health Sciences University Tepecik Training and Research Hospital between 2012 and 2022 and were diagnosed with ureterocele were evaluated retrospectively. Demographic, clinical, and laboratory data were obtained from file records. Results: All patients diagnosed with ureterocele and voiding cystourethrography (VCUG) were evaluated. A total of 24 (female 13 (54.2%)) children were included. The reasons for admission were antenatal hydronephrosis in 13 (54.2%) patients, UTI in 9 (37.5%) patients, and incidentally diagnosed ureterocele in 2 (8.3%) patients. Urinary tract infection was observed in 20 patients at admission, recurrent UTI in 21 patients at follow-up, preoperative pyelonephritis in 12 patients. VUR was found in 11 patients, and severe VUR (≥stage 3) was found in 9 patients. Ten patients had ipsilateral hydronephrosis, and 14 patients had a double collecting system. The presence of VUR was found to be associated with female gender, UTI at admission, and recurrent UTI at follow-up (p < 0.05). However, there was no difference between groups with or without VUR in terms of ipsilateral hydronephrosis, scar formation, and the need for surgery (p > 0.05). Conclusions: We could not demonstrate any criteria to select patients to receive VCUG; on the other hand, VUR did not cause more kidney damage. Our study supports the need for more scientific data to determine management in patients with ureterocele. [ABSTRACT FROM AUTHOR]

A clinical quiz about the cause of chronic tubulointerstitial nephritis in pediatric patients is presented.

Background: Patients with nephrotic syndrome (NS) are at a high risk of cardiovascular disease, obesity, and dyslipidemia. The aim of this study was to evaluate the formation of epicardial adipose tissue (EAT) and investigate electrocardiographic (ECG) parameters in patients. Methods: Thirty-two patients aged 0–18 years and 15 control patients were compared. In the patient group, physical examination and laboratory parameters were recorded. Atrial depolarization and ventricular repolarization parameters in ECG were compared between the groups. EAT was evaluated with M-mode measurements on echocardiography. Results: There was no difference between the groups in terms of sex, age, body mass index, systolic and diastolic BP. EAT was found to be significantly higher in the patient group. In ECG evaluations it was determined that atrial depolarization and ventricular repolarization parameters increased in the patient group. Conclusions: Cardiovascular morbidity and mortality are high in kidney diseases. Measurement and follow-up of EAT and ECG findings as a noninvasive parameter can provide information in NS.

Aim: Kidney transplantation is the most preferred long-term treatment of children with end stage renal disease since 1954. Graft dysfunction has been divided into three categories based on timing of presentation. In this article, we aim to present the etiologic factors of acute graft dysfunction in the first year of renal transplantation in children. Materials and Methods: The patients, diagnosed with acute allograft dysfunction in first year of kidney transplantation, in University of Health Sciences Turkey, Tepecik Training and Research Hospital between March 2005 and October 2017 were analyzed prospectively in this study. Results: Over the 15 year period, 56 pediatric renal allograft patients were followed in University of Health Sciences Turkey, Tepecik Training and Research Hospital. During this period, 25 patients had diagnosed with early allograft dysfunction. Five patients were admitted two times in a year with allograft dysfunction. The mean age of patients was 12.6 (4.0±21.0) years, with a male and female ratio of 17:8. Delayed graft function was occurred in four patients (16%). Among 25 renal allograft recipients showed early graft dysfunction on average of 4.2 months (1-10 months) after transplantation. The etiology of early graft dysfunction showed 10% immunologic diseases and 90% non-immunologic factors. Five patients (16.7%) diagnosed with urinary tract infection, one patient (3.3%) diagnosed with cytomegalovirus nephropathy, five patients (16.7%) diagnosed with BK nephropathy, eight patients (26.7%) diagnosed with acute cyclosporine toxicity, seven patients (23.3%) were diagnosed with dehydration and one patient (3.3%) diagnosed with urologic anomalies. Twelve patients had performed renal allograft biopsy. The histological findings were consistent with T-cell mediated rejection in two patients; B-cell mediated rejection in one patient and viral nephropathy in five patients. Non-specific histological findings were determined in five patients. Conclusion: Early recognition of the etiology of graft dysfunction that develops at 1 year and appropriate treatment will contribute to the preservation of long-term graft dysfunction.

Introduction: Multisystem inflammatory syndrome in children (MIS-C) is a rarely seen severe complication of coronavirus disease-2019 (COVID-19). Although fever is one of the indispensable symptoms, other infections should be considered in the differential diagnosis during the pandemic. Case report: An 8-year-old and a 16-year-old female patient were admitted with fever, vomiting, headache. Both had fulfilled the criteria and were diagnosed with MIS-C. However, they both had remarkable persistent costovertebral angle tenderness, which was unexpected in MIS-C. In Case-1, urine analysis showed microscopic hematuria without pyuria, and urine culture showed no bacterial growth. Case-2 had microscopic hematuria and pyuria with Escherichia coli growth in urine culture. Contrastenhanced computed tomography showed wedge-shaped hypodense multiple lesions in bilateral kidneys for Case-1, in the right kidney for Case-2. They diagnosed acute focal bacterial nephritis (AFBN). Conclusions: The diagnostic criteria of MIS-C can overlap with the symptoms of other severe septic infections such as AFBN, which is a rare urinary tract infection, diagnosed by imaging of localized renal inflammatory mass-like or wedge-shaped lesion. A detailed anamnesis and careful physical examination may help differential diagnosis. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to present the demographic, clinical, and laboratory features of children clinically diagnosed with familial Mediterranean fever (FMF) and to predict more severe mutations by evaluating those findings. Methods: We enrolled cases diagnosed with FMF with a defined variation in at least one allele. The medical charts of the patients were reviewed retrospectively. The patients were grouped as homozygous, compound heterozygous, and simple heterozygous cases, with and without M694V mutation. We compared the data between the subgroups using logistic regression analysis and determined the risk factors for being homozygous or compound heterozygous for M694V. Results: A total of 263 (M/F =109/154) cases were included. The mean age at the onset of symptoms, follow-up duration, and time to diagnosis were 6.75 ± 3.9 (0.25-17) years, 51.78 ± 39.31 (6-166) months, and 9.23 ± 14.44 (1-132) months, respectively. The rates of parental consanguinity, positive family history for FMF, and FMF in a first-degree relative were 15%, 42%, and 31.4% respectively. The most common symptom was abdominal pain (85%). There was no difference between the growth parameters of the cases during the initial and final control periods. The most frequent alleles were M694V, E148Q, and V726A. The most common accompanying disease was IgA vasculitis (20%). Almost 90% of the cases fulfilled all the defined criteria. The rate of patients having a first-degree relative with FMF was higher, Hb values were lower, and the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values were higher during the attack period; the ESR and CRP values were higher in the attack-free period; and Pras disease severity scores were higher in homozygous or compound heterozygous cases carrying M694V. The presence of FMF in a first-degree relative increases the probability of being homozygous and compound heterozygous for M694V by a factor of 2.39; and each 1 unit increase in the Pras score increases this probability by a factor of 1.43. The threshold Pras score for this possibility is 5.5 (AUC = 0.651; 95% CI, 0.545-0.757; P = .006; sensitivity, 65%; specificity, 55%). Conclusion: M694V was the most common and severe mutation in our cohort. The presence of a first-degree relative with FMF and Pras scores >5.5 may predict a homozygous or compound heterozygous mutation for M694V. [ABSTRACT FROM AUTHOR]

Aim: Enuresis (EN) is a common problem in childhood. Family physicians have an important role in revealing children with EN. The aim of this study was to assess the knowledge and attitude of family medicine (FM) residents regarding the diagnosis and treatment of enuresis in children. Materials and Methods: Family medicine residents of the University of Health Sciences, İzmir Tepecik Training and Research Hospital were invited to complete a questionnaire concerning enuresis in children. Those who had completed their paediatrics rotation training were defined as group 1, and those who had not completed their paediatrics rotation as group 2. The responses were compared between the groups. Results: Sixty (88%) of the FM residents agreed to complete the survey. The mean age of the participants was 28.7 (25-35) years, 38 (63%) had completed their paediatrics rotation (group 1). The question about the age of night-time bedwetting was more often answered correctly in group 1 (19/38) (p=0.025). In the question on the symptoms of non-monosymptomatic enuresis; the constipation option was marked as a symptom by only 15 of the participants (25%), with 13 (87%) being in group 1 (p=0.03). The correct response rates to the questions about other symptoms of non-monosymptomatic enuresis, the causes of secondary enuresis, the need for treatment, treatment options and the follow-up of patients with enuresis were similar between groups 1 and 2. Conclusion: As a result of this study, more correct answers, which revealed adequate knowledge and experience regarding enuresis, were obtained from those who had concluded their paediatrics rotation.

Background/aim: In children with autosomal dominant polycystic kidney disease (ADPKD), clinical manifestations range from severe neonatal presentation to renal cysts found by chance. We aimed to evaluate demographic, clinical, laboratory findings, and genetic analysis of children with ADPKD. Materials and methods: We evaluated children diagnosed with ADPKD between January 2006 and January 2019. The diagnosis was established by family history, ultrasound findings, and/or genetic analysis. The demographic, clinical, and laboratory findings were evaluated retrospectively. Patients <10 years and ≥10 years at the time of diagnosis were divided into 2 groups and parameters were compared between the groups. Results: There were 41 children (M/F: 18/23) diagnosed with ADPKD. The mean age at diagnosis was 7.2 ± 5.1 (0.6-16.9) years and the follow-up duration was 59.34 ± 40.56 (8-198) months. Five patients (12%) were diagnosed as very early onset ADPKD. All patients had a positive family history. Genetic analysis was performed in 29 patients (PKD1 mutations in 21, PKD2 mutations in 1, no mutation in 3). Cysts were bilateral in 35 (85%) of the patients. Only one patient had hepatic cysts. No valvular defect was defined in 12 patients detected. Only 1 patient had hypertension. None of them had chronic kidney disease. No difference could be demonstrated in sex, laterality of the cysts, maximum cyst diameter, cyst or kidney enlargement, follow-up duration, or GFR at last visit between Groups 1 and 2. Conclusion: The majority of children with ADPKD had preserved renal functions and slight cyst enlargement during their follow-up. However, they may have different renal problems deserving closed follow-up. [ABSTRACT FROM AUTHOR]

Patients with solitary kidneys (SKs) are at risk of hypertension (HT) and associated end‐organ damage. The authors aimed to evaluate whether children with congenital SKs (CSKs) have higher office, ambulatory, or central blood pressure (BP), increased arterial stiffness or left ventricular mass index, or any risk for arrhythmia. With this purpose, patients with CSK and healthy controls being followed up between January 2018 and June 2019 were enrolled in the study. Demographic, biochemical, and office blood pressure (BP) data were recorded. Then, ambulatory blood pressure monitoring (ABPM) and measurements of central BP (cBP), pulse wave velocity (PWV), and augmentation index (AIx@75) were obtained. Ventricular repolarization parameters were acquired by 12‐lead electrocardiography. Left ventricular mass index (LVMI) and abdominal aortic stiffness parameters including strain, pressure strain elastic modulus (Ep), and normalized Ep (Ep*) were calculated with echocardiographic measurements. Finally, 36 children with CSK and 36 healthy controls were included. Serum creatinine, uric acid, total cholesterol levels, ABPM parameters, cBP levels, and PWV values were significantly higher, and eGFR levels were significantly lower in the CSK group. VR parameters, abdominal aortic stiffness indices, and LVMI were similar between the groups. CSK increased the risk of HT in ABPM (HTABPM) by 6 times. PWV was significantly correlated with Ep and Ep* in cases with CSK. Determination of cBP and PWV along with 24‐hour ABPM would be a useful tool in children with CSK. [ABSTRACT FROM AUTHOR]

Objectives: Copeptin, the C-terminal part of arginine-vasopressin, is increased in hypertensive adolescents and closely associated with metabolic syndrome (MS). We aimed to investigate whether serum copeptin can be used to differentiate masked hypertension (MHT) and MS, and the role of sodium intake, natriuretic peptide response and renin-angiotensin-aldosterone system in MHT and MS in obese youth. Methods: Obese children aged 10–18 years with normal office blood pressure measurements were included. Patients with MHT and normotension and those with MS and non-MS were evaluated separately. Biochemical parameters, copeptin, brain natriuretic peptide (BNP), aldosterone, renin, urine sodium, and protein were evaluated. Echocardiography, fundoscopic examination, and ambulatory blood pressure monitoring were performed. Results: There were 80 (M/F=39/41) obese patients with a mean age of 13.78 ± 1.93 years. The cases with MHT, MS, and concomitant MHT and MS were 53,24, and 13%, respectively. Copeptin levels were similar among patients with and without MHT or MS (p>0.05). However, multivariate analysis revealed that copeptin significantly increased the probability of MHT (OR 1.01, 95% CI=1.001–1.018, p=0.033). Copeptin was positively correlated with daytime systolic and diastolic load, aldosterone, BNP, and urine microalbumin/creatinine levels (p<0.05). Linear regression analyses revealed that copeptin was significantly correlated with BNP regardless of having MHT or MS in obese youth. In the MHT group, 24-h sodium excretion was not significantly correlated with BNP. Conclusion: Copeptin may be a beneficial biomarker to discriminate MHT, but not MS in obese children and adolescents. An insufficient BNP response to sodium intake might be one of the underlying causes of MHT in obese cases. [ABSTRACT FROM AUTHOR]

Polyarteritis nodosa (PAN) is a necrotizing systemic vasculitis involving the wall of small and medium sized arteries. The histological aspect is defined by the presence of fibrinoid necrosis and an infiltrate rich in neutrophil polynuclears in the artery wall and rare granulomas. CECR1 (Cat Eye Syndrome Chromosome Region 1) gene mutation causing adenosine deaminase 2 (ADA2) deficiency is also associated with systemic inflammation, vasculopathy, and frequently PAN. Strokes, neurological involvement, and gastrointestinal involvement have poor prognosis in the cases with ADA2 deficiency particularly in early stage. In this article, we report a 17-year-old male patient diagnosed with PAN who had severe gastrointestinal system involvement that was resistant to intensive and conventional immunosuppressive treatment and showed a fatal course despite the emergency surgical intervention. After the patient was exitus, he was detected to have a heterozygous mutation (V276A) of familial Mediterranean fever (FMF) and also a homozygous ADA2 mutation. The aim of this article is to highlight that ADA2 deficiency may be present in treatment-resistant PAN cases who apply due to severe systemic involvement. In this case, accompanying FMF mutation was also observed. [ABSTRACT FROM AUTHOR]
