Aim: Aim of the study was to determine if carotid intima media thickness in children with idiopathic nephrotic syndrome is greater than in healthy subjects, and to assess whether carotid intima media thickness in children with nephrotic syndrome is associated with clinical (including disease duration, cumulative dose of steroids, number of relapses) and biochemical parameters. Methods: A cross-sectional study included 40 patients with nephrotic syndrome (mean age 11.7 ± 4.7 years). Steroid dependent nephrotic syndrome was established in 32 patients (80%), while 8 (20%) had steroid resistant nephrotic syndrome. Control group consisted of 20 age and gender matched healthy children. Blood pressure based on 24-h ambulatory blood pressure monitoring (ABPM), carotid intima media thickness, fasting glucose, insulin, HbA1c, lipid concentrations were measured in all children. Results: A significant difference was detected in carotid intima media thickness values (P = 0.036). Children with nephrotic syndrome had significantly greater carotid intima media thickness compared with healthy children (0.42 ± 0.06 and 0.38 ± 0.03 mm). Carotid intima-media thickness was positively associated with duration of nephrotic syndrome (r = 0.45; P = 0.004), body mass index (r = 0.48; P = 0.002), daytime systolic blood pressure (r = 0.46; P = 0.003) and night-time systolic blood pressure (r = 0.52; P = 0.001). Multiple linear regression showed that duration of nephrotic syndrome was the only independent predictor of carotid intima media thickness in children with nephrotic syndrome (R2 = 0.244; β=0.327; P = 0.037). Conclusion: The findings of the present study suggest subclinical vascular damage in patients with nephrotic syndrome. Duration of nephrotic syndrome was the only independent predictor of carotid intima media thickness. © 2020 Société francophone de néphrologie, dialyse et transplantation

Background: Growth retardation is one of the most visible comorbid conditions of chronic kidney disease (CKD) in children. To our knowledge, published data on longitudinal follow-up of growth in pediatric patients with CKD is lacking from the region of South-East Europe. Herein we report the results from the Serbian Pediatric Registry of Chronic Kidney Disease.; Methods: The data reported in the present prospective analysis were collected between 2000 and 2012. A total of 324 children with CKD were enrolled in the registry.; Results: Prevalence of growth failure at registry entry was 29.3 %. Mean height standard deviation scores (HtSDS) in children with stunting and those with normal stature were −3.00 [95 % confidence interval (CI) −3.21 to −2.79] and −0.08 (95 % CI −0.22 to 0.05) (p < 0.001), respectively. Children with hereditary nephropathy had worse growth at registration (−1.51; 95 % CI −1.97 to −1.04, p = 0.008). Those with CKD stages 4 and 5 before registration had more chance to have short stature at registration than those with CKD stages 2 and 3 [odds ratio (OR) = 0.458, CI 0.268–0.782, p = 0.004]. Dialysis was an independent negative predictor for maintaining optimal stature during the follow-up period (OR = 0.324, CI = 0.199–0.529, p < 0.001), while transplantation was an independent positive predictor for improvement of small stature during follow-up (OR = 3.706, CI = 1.785–7.696, p < 0.001).; Conclusion: Growth failure remains a significant problem in children with CKD, being worst in patients with hereditary renal disease. Growth is not improved by standard dialysis, but transplantation has a positive impact on growth in children. © 2014, Italian Society of Nephrology.

Renal tubular acidosis (RTA) is common in adults with primary Sjogren syndrome (pSS) but to date this condition has only been identified in 12 pediatric cases of pSS. Here we present the case of a 13-year-old, otherwise asymptomatic girl in whom the search for the etiology of incidentally found nephrocalcinosis led to diagnosis of distal RTA and nephrogenic diabetes insipidus secondary to SS-associated tubulointerstitial nephritis. Immunosupressive treatment and alkali/electrolyte supplementation resulted in stable renal function over the 6-year follow-up. A review of the literature focuses on two aspects of pSS: (1) the difficulties in diagnosing pSS in childhood and (2) clinical-pathological features, treatment and outcome of renal tubulointerstitial disease in childhood pSS. SS should be considered in older children, particularly females with otherwise unexplained RTA. A careful search for other renal dysfunctions is necessary, and renal biopsy may be of value in assessing the extent of renal damage and the need for immunomodulatory therapy. © 2012 Japan College of Rheumatology.

Eight boys aged 2-12 weeks with urinary tract malformations (UTMs) exhibited features of transient type 1 pseudo-hypoaldosteronism (TPHA1) in the course of urinary tract infection (UTI). Hyponatremia (120.9±5.8 mmol/l), hyperkalemia (6.9±0.9 mmol/l), metabolic acidosis (plasma bicarbonate 11±1.4 mmol/l), and a rise in serum creatinine levels (145±101 μmol/l) were associated with high urinary sodium (Na) and low potassium (K) excretion. Tubular resistance to aldosterone was indicated by high plasma aldosterone concentrations (170.4±100.5 ng/dl), high levels of the plasma aldosterone to potassium ratio (25.2±15.6), and diminished urinary K/Na values (0.31±0.19). With appropriate therapy, serum electrolytes, creatinine, and acid-base balance normalized within 2 weeks. A Medline search revealed another 85 cases of TPHA1 reported to date. All of the 93 patients were less than 7 months of age and 90% were less than 3 months of age, 90.3% suffered from UTM, with associated UTI in 89% of them, 11% had UTM in the absence of UTI, and 9.7% showed isolated UTI. These findings indicate that early infancy is the main contributing factor for TPHA1 to occur and that UTI and UTM are additional factors, with at least one being required for its development. © IPNA 2009.
