PURPOSE: The purposes of this study were to describe the relationship between depression and resilience and to identify variables associated with depression among children with nephrotic syndrome. METHOD: Data was collected from 45 children who were registered at one hospital in Seoul. The criteria for sample selection were 10 to 15 year-old children who were diagnosed at least 6 month prior. The instruments included a self-reported questionnaire on resilience by Kim, CDI by Beck, and MBRI by Kwak. Descriptive, Pearson correlation and multiple regression analyses were done. RESULT: The mean score of depression was 11.44 (range:0-54) and resilience was 97.47 (range:32-128). There were significant positive relationships between depression and age (r=0.302, p<.005) and academic achievement (r=-0.318, p<.005). In addition, negative relationships between depression and maternal attitude (r=-0.412, p<.001) and resilience (r=-0.649, p<.001) occurred. The results of multiple regression analysis showed that maternal behavior (beta=-0.421, p<.005) and resilience (beta=-0.639, p<.001) were related to depression. CONCLUSION: Children with higher resilience and with an affectionate mother were less depressed. Thus, it is important to identify strengths of children and help them to increase resilience and implement parenting and counseling programs for parents' of these children. Similar studies with children with other chronic illnesses are needed.

INTRODUCTION: The study was performed to determine the psychological problems in children with idiopathic nephrotic syndrome (INS) while they were on steroid therapy, as compared to healthy children. METHODS: This prospective cohort study was conducted in a paediatric clinic of a tertiary hospital. Parents of the participants in the INS group and control group (comprising children without chronic illness) completed questionnaires using the Child Behavioural Checklist (CBCL). The CBCL measures a range of age-specific emotional and psychological problems, including internalising and externalising domains. Analyses of the CBCL scores between groups were done using Mann-Whitney U test. RESULTS: A total of 140 children were recruited with an equal number in the INS and control groups. There was a significant difference in the mean total CBCL scores between the INS group and the control group, specifically in the withdrawal, somatic, anxious and aggressiveness subdomains. Similar findings were demonstrated in correlation between total psychological problems and corticosteroid dosage. In the INS group, steroid dose and cushingoid features were found to have a significant positive association with internalising psychological problems. CONCLUSION Children with INS on corticosteroid treatment showed an increase in internalising and externalising scores, as compared to healthy children.

PURPOSE: The purpose of this study was to develop and evaluate a Korean questionnaire to measure resilience in children with chronic illness. METHODS: Item construction was drawn from an extensive review of the literature, existing questionnaires and interviews with parents. Content validity was tested by experts. To further refine the questionnaire and test its reliability and validity, data were collected from the 202 children with asthma, diabetes mellitus or nephrotic syndrome. Corrected items were used to total correlation coefficient and test-retest reliability. Questionnaire testing was conducted using factor analysis, Cronbach's alpha, and correlation coefficients. Validity of the questionnaire was tested using internal consistency, construct validity, and criterion-related validity. RESULTS: Components of the questionnaire were in three domains; interpersonal characteristics, characteristics of coping, and intrapersonal characteristics. Factor analysis is showed five factors; positive self-understanding, self-reliance, resourcefulness, perception of positive family relationships, and intimacy. The questionnaire showed a high internal consistency. A significant positive correlation with the Numerical Rating Score and negative correlation with the Child Depression Inventory support the validity of the questionnaire. CONCLUSION: This instrument demonstrated high reliability and validity. Therefore, this instrument can contribute to the evaluation of resilience of chronically ill children and to any subsequent intervention as well as to develop a theory for resilience.

Sodium retention is a hallmark of nephrotic syndrome. We investigated whether sodium retention is associated with changes of natriuretic peptide system at different stages (i.e., a sodium retaining stage and a compensatory stage) of nephrotic syndrome. At day 7 after PAN (puromycin aminonucleoside) injection, the urinary excretion of sodium was decreased, along with the development of ascites and positive sodium balance. The plasma and urinary ANP (atrial natriuretic peptide) immunoreactivities were increased. ANP mRNA expression was increased in the heart and kidney, whereas that of NPR (natriuretic peptide receptor)-A and NPR-C mRNA was decreased in the kidney. The expression of NEP was decreased in the kidney. At day 14, urinary excretion of sodium did not differ from the control. The plasma ANP level and heart ANP mRNA expression returned to their control values. The expression of ANP mRNA in the kidney was increased in association with increased urinary ANP immunoreactivities. The expression of NPR-A in the kidney became normal, whereas that of NPR-C kept decreased. The expression of NEP (neutral endopeptidase) remained decreased. These findings suggest that the increased renal ANP synthesis in association with decreased metabolism via NEP and NPR-C may play a compensatory role against the development of sodium retention in nephrotic syndrome. The decreased of NPR-A expression in the kidney may contribute to the ANP resistance at day 7. The subsequent recovery of NPR-A expression may play a role in promoting sodium excretion in later stage (at day 14).

PURPOSE: The aim of our study was to evaluate the therapeutic response to cyclosporine, time to remission and side effects in steroid resistant nephrotic syndrome (SRNS). METHODS: This study included 22 children with idiopathic SRNS who were treated with cyclosporine between June 1989 and August 2006. Medical records were reviewed retrospectively. RESULTS: The mean age of patients at diagnosis was 5.2+/-3.3 years. The male to female ratio was 1.2:1. Pre-treatment renal biopsies showed minimal change (MCD) in 12 (54.5%), focal segmental glomerulosclerosis (FSGS) in 8 (36.4%), membranous nephropathy (MGN) in one (4.5%) and mesangioproliferative glomerulonephritis in one (4.5%). 15 (68.2%) patients responded to cyclosporine, of whom 11 (91.6%) patients were MCD, 3 (37.5%) patients FSGS, and 1 patient MGN (MCD vs FSGS, P<0.05). The time to remission in patients who responded to cyclosporine was 31.5+/-15.2 days. Four of the 15 cyclosporine responders maintained complete remission even after cessation of the medication Seven still received cyclosporine, 2 were intermittently treated with steroids after discontinuation of cyclosporine, and two were treated with cyclosporine and steroids. The mean duration of cyclosporine therapy was 546.5+/-346.2, 1,392.9+/-439.7, 439.5+/-84.1, and 433.5+/-74.2 days, respectively. We performed post-treatment biopsies in 8 patients and partial interstitial fibrosis and tubular atrophy were found in two. CONCLUSION: The thrapeutic response of cyclosporine is good in steroid resistant nephrotic syndrome, especially in minimal change. But, there is a problem of long term cyclosporine dependency.

The collecting duct endothelin (ET) system, which involves ET-1 and its two receptors, may play a role in the regulation of renal sodium in association with the nitric oxide synthase (NOS) system. We determined whether sodium retention is associated with changes in the endothelin and NOS systems at different stages (i.e., a sodium retaining stage and a compensatory stage) of nephrotic syndromes. On day 7 after puromycin aminonucleoside (PAN) injection, urinary sodium excretion was decreased, ascites had developed, and there was a positive sodium balance. ET-1 mRNA expression was increased in the inner medulla of the kidney, whereas protein expression of ET receptor type B (ET(B)R) was unchanged. The expression of neuronal NOS (nNOS) was decreased in the inner medulla. On day 14, urinary sodium excretion was unchanged compared with controls. The expression of ET(B)R increased, while nNOS expression in the inner medulla was comparable to controls. These findings suggest that decreased nNOS plays a role in the development of sodium retention in the nephrotic syndrome. Recovery of nNOS and increased renal ET(B)R synthesis may promote sodium excretion in later stages of the nephrotic syndrome (on day 14).
