Depressive disorders in children with chronic kidney disease treated conservatively.

Background: Children with chronic kidney disease (CKD) experience a lot of mental and emotional stress, which can lead to the development of depressive disorders. The prevalence of depressive disorders in CKD children is estimated to be between 7% and 35%.

Objectives: The aim of our study was to analyze the prevalence and characteristics of depression and depressive symptoms in children and adolescents with CKD treated conservatively.

Effect of cyclosporin A on proteinuria in the course of glomerulopathy associated with WT1 mutations.

Denys-Drash syndrome (DDS) is characterized by progressive glomerulopathy caused by diffuse mesangial sclerosis (DMS), genitourinary defects, and a higher risk of developing Wilms' tumor. It is commonly assumed that the DMS is unresponsive to any medications. In this report, we present a patient with Denys-Drash syndrome, in whom the cyclosporine A (CsA) was found to induce total remission.

Urinary levels of matrix metalloproteinases and their tissue inhibitors in nephrotic children.

The aim of this study was to determine the effects of cyclosporine A (CyA) on urinary levels of matrix metalloproteinase 2 and 9 (MMP2, MMP9) and their tissue inhibitors 1 and 2 (TIMP1, TIMP2) in steroid-dependent nephrotic syndrome (SDNS). The study group (1) consisted of 18 children SDNS aged 3.5-17.

Expression of P-glycoprotein in lymphocytes of children with nephrotic syndrome treated with glucocorticoids.

Introduction: Glucocorticoids are still the mainstay of therapy for nephrotic syndrome (NS) in children. Poor response to glucocorticoids may relate, in part, to the overexpression of P-glycoprotein (P-gp). The aim of the present study was to determine the expression of P-gp in lymphocytes (CD3) in the peripheral blood of children with steroid-sensitive nephrotic syndrome in the dynamics of the disease.

[Assessment of oxalate concentration in serum and urine of children with renal stones].

Unlabelled: Oxalate crystals are the main component of renal stones and oxalate urolithiasis is the most common type both in adults and children. The aim of the work was the assessment of oxalate concentration in plasma and urine of children with renal stones.

Material: The examined group (I) consisted of 29 children (12.

[Urinary concentration of proinflammatory cytokines with regard to infected urinary tract region].

Unlabelled: Uropathogenic bacteria stimulate epithelial cells of interstitial tissue and macrophages to secrete proinflammatory cytokines: interleukin I (IL-1beta), interleukin 6 (IL-6) and interleukin 8 (IL-8). The aim of the study was to check: 1) if the concentration of proinflammatory cytokines (IL-1beta, IL-6, IL-8) differs in dependence on region and clinical picture of urinary tract infection, 2) what is the influence of antibacterial treatment on their concentration.

Material: We examined 67 children, aged 1-15 years, who were divided into 3 groups: 27 children with acute pyelonephritis (AP), caused by E.

Transforming growth factor-beta1 in nephrotic syndrome treated with cyclosporine and ACE inhibitors.

The aim of the study was to assess urinary transforming growth factor (TGF)-beta1 in children with steroid-dependent nephrotic syndrome (SDNS) treated with cyclosporine A (CyA) and ACE inhibitors (ACEI). The study involved 24 children (14 boys and 10 girls) with SDNS and signs of focal segmental glomerulosclerosis. The children were treated with prednisone, CyA, and ACEI.

Platelet-derived growth factor and platelet profiles in childhood nephrotic syndrome.

The aim of the study was to investigate (1) whether there are any changes in release of platelet-derived growth factor AA (PDGF AA) in children with nephrotic syndrome without clinical thromboembolic symptoms 2; (2) whether serum PDGF AA correlates with the platelet count (PLT) and platelet indices; (3) whether prednisone therapy affects the serum PDGF AA and the PLT; (4) whether PDGF AA is a useful predictor of disease activity. The study involved two groups of children: 33 with nephrotic syndrome (I) who were evaluated twice (A during relapse and B after 2 weeks of prednisone treatment) and 34 healthy children (II). The serum concentration of PDGF was measured by ELISA.
