RESUMEN

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. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMEN

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.

RESUMEN

BACKGROUND: Since the emergence and worldwide spread of the new coronavirus (COVID-19) pandemic, it has caused people to experience adverse psychological effects. This study aimed to assess anxiety levels during COVID-19 in children with chronic kidney disease (CKD), including nephrotic syndrome (NS) and kidney transplantation (Tx). METHODS: A case-controlled, cross-sectional study was conducted with children aged 10-18 years, who had a diagnosis of CKD or NS, or Tx, and followed in our center between April and July 2020. A healthy control group was recruited with age- and gender-matched children. A questionnaire with printed and online versions was designed in three parts: the first addressed demographic characteristics, the second addressed opinions about the pandemic, and the third was the Turkish version of the Revised Child Anxiety and Depression Scale - Child Version. RESULTS: A total of 88 children completed the questionnaire. The patient and control groups were similar in terms of gender, age, household members and history of psychiatric treatment. Both groups stated that coronavirus is a risky disease for children (63.6%), and that they were afraid of contagion (69.3%). Only half of them were receiving realistic and informative answers from family members. In the Revised Child Anxiety and Depression Scale - Child Version, 66% of them received a high score on at least one subscale. The social phobia scores of the control group were higher than those of the patient group, although the proportion of high scores was similar in both groups. The ratio of high-scored participants was higher in CKD patients for panic disorder, and was lower in the immunosuppressive agent group for social phobia. CONCLUSION: The current COVID-19 pandemic is a disaster that children encounter for the first time in their lives. It does not exclusively cause anxiety among children with chronic kidney diseases but also affects healthy children.

RESUMEN

AIM: Urinary tract infections (UTIs) represent a common febrile illness in infancy. The study compared two UTI guidelines in terms of number of imaging studies, presence of parenchymal damage and radiation exposure in patients with the first febrile UTI between 2 and 24 months of age. METHOD: The results of Tepecik UTI Guideline-1 used until 2012 (Group 1, n = 105) were retrospectively compared with Tepecik UTI Guideline-2 (Group 2) used after 2013. In Group 1, urinary tract ultrasonography (US), dimercaptosuccinic acid (DMSA) and voiding cystourethrography (VCUG) were made in all patients. In Group 2, if the US result was abnormal, patients were evaluated with VCUG and DMSA. If the US was normal, only DMSA was performed. If the DMSA was abnormal, the VCUG was undergone (n: 43, 40.9%). RESULTS: The abnormal VCUG detection rate was 69.2% in Group 1 and 30.8% in Group 2 (p = 0.09). Sensitivity and specificity of US in the diagnosis of vesicoureteral reflux (VUR) was 15.9% and 96.7% in Group 1 and 61.5% and 70.5% in Group 2, respectively. Abnormal DMSA findings were observed among 33.3% (Groups 1) and 66.7% (Groups 2) subjects, respectively (p > 0.05). The median radiation exposure (500 mrem) of patients in Group 1 was statistically significantly higher than those in Group 2 (200 mrem) (p < 0.001). CONCLUSION: The VCUG should not be the first examination to be considered in such patients. We think that Tepecik UTI Guideline-2 reduces unnecessary invasive procedure and radiation exposure and not missed VUR in the management of children with UTI at 2-24 months. Needs prospective follow-up studies before considering this recommendation.

RESUMEN

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 (0.6­16.9) years and the follow-up duration was 59.34 ± 40.56 (8­198) 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.

RESUMEN

BACKGROUND: Hemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia. It very rarely coexists with acute lymphoblastic leukemia (ALL) emerging before, simultaneously, or after the diagnosis has been made, and management of the patient may be difficult. CASE: We present the case of a 7-year-old boy who was diagnosed with HUS and initially managed by hemodialysis (HD). Thereafter, HUS progressed, and neurological findings developed. The patient was treated with eculizumab, agressive blood pressure control, and antiepileptic drugs. At the fifth month of follow-up, the patient was diagnosed with acute B-cell lymphoblastic leukemia with fever, bone pain, hepatosplenomegaly, and pancytopenia. After initiation of ALL treatment, he had no episodes of HUS, despite cessation of eculizumab. CONCLUSION: In conclusion, eculizumab may be a treatment of choice to prevent further systemic damage in recurrent HUS episodes of patients with borderline changes in the bone marrow until ALL is constantly diagnosed.
