Chronic kidney disease among children in Guatemala
Objective. To describe the distribution of pediatric chronic kidney disease (CKD) in Guatemala, estimate incidence and prevalence of pediatric end-stage renal disease (ESRD), and estimate time to progress to ESRD. Methods. This study analyzed the registry of the only pediatric nephrology center in Guatemala, from 2004–2013. Incidence and prevalence were calculated for annual periods. Moran’s index for spatial autocorrelation was used to determine significance of geographic distribution of incidence. Time to progress to ESRD and associated risk factors were calculated with multivariate Cox regression. Results. Of 1 545 patients from birth to less than 20 years of age, 432 had chronic renal failure (CRF). Prevalence and incidence of ESRD were 4.9 and 4.6 per million age-related population, respectively. Incidence was higher for the Pacific coast and Guatemala City. The cause of CRF was undetermined in 43% of patients. Average time to progress to ESRD was 21.9 months; factors associated with progression were: older age, diagnosis of glomerulopathies, and advanced-stage CKD at consultation. Conclusions. Prevalence and incidence of ESRD in Guatemala are lower than in other countries. This may reflect poor access to diagnosis. Areas with higher incidence and large proportion of CKD of undetermined cause are compatible with other studies from the geographic subregion. Findings on progression to ESRD may reflect delayed referral.

Steroid-resistant nephrotic syndrome is a rare kidney disease involving either immune-mediated or genetic alterations of podocyte structure and function. The rare nature, heterogeneity, and slow evolution of the disorder are major obstacles to systematic genotype-phenotype, intervention, and outcome studies, hampering the development of evidence-based diagnostic and therapeutic concepts. To overcome these limitations, the PodoNet Consortium has created an international registry for congenital nephrotic syndrome and childhood-onset steroid-resistant nephrotic syndrome. Since August of 2009, clinical, biochemical, genetic, and histopathologic information was collected both retrospectively and prospectively from 1655 patients with childhood-onset steroid-resistant nephrotic syndrome, congenital nephrotic syndrome, or persistent subnephrotic proteinuria of likely genetic origin at 67 centers in 21 countries through an online portal. Steroid-resistant nephrotic syndrome manifested in the...
Quality of life in children with chronic kidney disease (with child and parent assessments
Pediatric Nephrology, 2010
Herein the results of a multicenter study from the Turkish Pediatric Kidney Transplantation Study Group are reported. The aims of this study were to compare the quality of life (QoL) scores of Turkish children who are dialysis patients (DP), renal transplant recipients (TR), and age-matched healthy controls and to compare child-self and parent-proxy scores. The Turkish versions of the Kinder Lebensqualität Fragebogen (KINDL®) questionnaires were used as a QoL measure. The study group consisted of 211 children and adolescents with chronic kidney disease (CKD) (139 TR and 72 DP aged between 4–18 years; 13.7 ± 3.5 years) from 11 university hospitals, 129 parents of these patients, 232 age-matched healthy children and adolescents (aged between 4–18 years; 13.1±3.5 years) and 156 of their parents. Patients with CKD had lower scores in all subscales except for physical well-being than those in the control group. TR had higher scores in physical well-being, self-esteem, friends’ subscales, and total scores than DP. Child-self scores were lower than parent-proxy scores, especially in CKD, DP, and control groups. Concordance between parent-proxy and child-self reports in the TR, DP, CKD, and control groups was only moderate for the majority of subscales (r = 0.41–0.61). It was concluded that parent-proxy scores on the QoL were not equivalent to child-self scores and that evaluating both children’s and parents’ perspectives were important. Additionally, psychosocial counseling is crucial not only for patients with CKD but also for their parents.

Background Cardiovascular complications are common in patients with end-stage renal disease (ESRD). We aimed to investigate left ventricular (LV) function and carotid intima-media thickness (cIMT) in children and adolescents with ESRD. Methods This study included 38 ESRD patients (15 hemodialysis and 23 peritoneal dialysis) and 17 age- and sex-matched healthy subjects. Results The ESRD patients had significantly lower mean mitral E/A ratio, and
Familial Mediterranean fever (FMF) in Turkey: results of a nationwide multicenter study
Medicine, 2005
Familial Mediterranean fever (FMF) is an autosomal recessive disease that is prevalent among eastern Mediterranean populations, mainly non-Ashkenazi Jews, Armenians, Turks, and Arabs. Since a large proportion of all the FMF patients in the world live in Turkey, the Turkish FMF Study Group (FMF-TR) was founded to develop a patient registry database and analyze demographic, clinical, and genetic features. The cohort was composed of 2838 patients (mean age, 23.0 +/- 13.33 yr; range, 2-87 yr), with a male:female ratio of 1.2:1. There was a mean period of 6.9 +/- 7.65 years from disease onset to diagnosis; the period was about 2 years shorter for each decade since 1981. Ninety-four percent of patients were living in the central-western parts of the country; however, their familial origins (70% from the central-eastern and Black Sea regions) reflected not only the ongoing east to west migration, but also the historical roots of FMF in Turkey. Patients' clinical features included perit...
