Steroid Regimen

AbstractSteroids are the cornerstone of the treatment of childhood nephrotic syndrome. The optimal duration for the first episode remains a matter of debate. The aim of this study is to determine whether the 8 weeks International Study of Kidney Disease in Children (ISKDC) regimen is equally effective as the 12 weeks steroid regimen from the German society of pediatric nephrology (Arbeitsgemeinschaft für Pädiatrische Nephrologie [APN]). An individual patient data (IPD) meta-analysis of randomized controlled trials reporting on prednisolone treatment for a first episode of childhood nephrotic syndrome was conducted. European trials aimed at investigating the ISKDC and/or APN steroid regimen were selected. The lead investigators of the selected trials were requested to provide the IPD of the specific treatment groups. Four trials included European cohorts using dosing schedules according to the regimens studied. IPD of two trials were available. A significant difference was found in time to first relapse after cessation of steroid treatment between the 8 and 12 weeks treatment group with a median time to relapse of 29 and 63 days, respectively. Moreover, relapse rate ratios during total follow-up were 51% higher for the 8 weeks regimen. Finally, younger children have a significantly lower time to first relapse and frequently relapsing nephrotic syndrome.Conclusions: The results of this IPD meta-analysis suggest that the 8 weeks steroid regimen for a first episode of steroid-sensitive nephrotic syndrome may not be equally effective as the 12 weeks steroid regimen. Moreover, this study highlights the importance of using uniform definitions to enable accurate comparison and interpretation of trial results.Trial registration: Registration number: CRD42020199244, date of registration 16-08-2020 What is Known:• Steroids are the cornerstone of the treatment of childhood nephrotic syndrome, however the optimal duration for the first episode remains a matter of debate.• Currently, the 8 weeks ISKDC protocol and 12 weeks APN protocol are among the most frequently used protocols in Europe. What is New:• The 8 weeks steroid regimen for a first episode of steroid-sensitive nephrotic syndrome may not be equally effective as the 12 weeks steroid regimen for the treatment of a first episode of nephrotic syndrome.• Younger children have a significantly shorter time to first relapse and time to frequent relapsing nephrotic syndrome.

Background: In pediatric patients with steroid-sensitive nephrotic syndrome, recent trials have revealed that a 2-month, short-term steroid regimen is not inferior to an extended steroid course. However, the optimal duration of initial steroid therapy for adult steroid-sensitive minimal change disease (MCD) remains unclear. Objectives: The aim of present study was to evaluate the effectiveness of a 2-month, short-term steroid regimen in the treatment of adult steroid-sensitive MCD patients. Method: This was a prospective observational study. Adult patients with steroid-sensitive MCD (n = 35) who were initiated on a short-term steroid regimen between January 2015 and June 2016 were included. The details of the regimen are as follows: (1) prednisolone was administered at an initial dose of 0.8–1.0 mg/kg/day and continued for 4–6 weeks and (2) dosage was reduced to 0.5–0.6 mg/kg/alternate day and continued for 4 weeks. Control patients (n = 140), who were treated using conventional steroid administration, were selected from our previous adult MCD cohort. All patients fulfilled the following criteria: biopsy-proven MCD, age ≥20 years, first episode of nephrotic syndrome, and attainment of complete remission within 4 weeks. The following parameters of patients who received short-term treatment regimen and control patients were compared: any relapse and frequent relapse, adverse events caused by steroid treatment and cumulative steroid dose. Results: Throughout the observation period (median: 17.3 months), 24 (68.6%) patients in the short-term group developed at least one relapse. The short-term regimen showed earlier occurrence of any relapse than the conventional regimen (adjusted hazard ratio [aHR] 2.45; 95% CI 1.51–3.97; p < 0.001), but there was no difference in frequent relapse (aHR 1.31; 95% CI 0.43–3.99; p = 0.63). None of the patients showed any symptoms of adrenal insufficiency after discontinuation of corticosteroids. The cumulative steroid dose during the observational period was significantly lower in the short-term group than in the conventional group. Conclusions: The short-term steroid regimen may represent an effective treatment option that ensures lower steroid exposure when treating adult steroid-sensitive MCD patients.

Background: Nephrotic syndrome is a notable chronic disease in children. The objective of this study was to compare the clinical and lab profile between steroid sensitive nephrotic syndrome and steroid resistant nephrotic syndrome at the onset of disease. Certain parameters were tested if they could be significate predictors of developing steroid resistance at the onset of first episode of nephrotic syndrome.Methods: Retrospective observation study done children 1-12 years diagnosed with nephrotic syndrome in Sri Ramachandra Medical College and Hospital, Department of Paediatrics, Chennai. Sample size 150. Period of study Jan 2013- Dec 2015. Variables considered were age at onset, sex, parental consanguinity with essential lab parameters done at the onset of nephrotic syndrome proteinuria, pyuria, microscopic hematuria, urine protein creatinine ratio, serum creatinine, serum triglycerides and serum albumin. Children less than 1 year of age, cases with secondary causes of nephrotic syndrome and steroid dependant nephrotic syndrome, children with incomplete records were not included in this study. 150 cases who fulfilled the study criteria were included in this study.Results: 75 cases of steroid sensitive nephrotic syndrome (SSNS) were compared with an equal number of steroid resistant nephrotic syndrome (SRNS). 85 children had onset of disease before 3 years of age and majority had 3+ proteinuria and males predominated in both the groups. The overall consanguinity rates were higher among SRNS group. Triglyceride level >300 mg/dl predominated in SRNS group along with a higher severity of hypoalbuminemia when compared to SSNS group. None of the parameters tested were significant predictors of developing SRNS subsequently.Conclusions: Comparing steroid sensitive with steroid resistance nephrotic syndrome, no lab parameter could identify the risk of a child developing steroid resistance subsequently. This could be a field of interest in future studies that could predict the development of steroid resistance at the onset of first episode of nephrotic syndrome itself.

Objectives: Nephrotic syndrome (NS) is described as the existence of nephrotic-range proteinuria along with edema, hyperlipidemia and hypoalbuminemia. NS is estimated to be 15 time more frequent in children as compared to adults. Relapse is a major problem while managing nephrotic children. This study was aimed to find out the frequency of relapse in children with first episode of steroid sensitive nephrotic syndrome (SSNS) during the first 12 months, after completion of 6 months steroid therapy. Study Design: Descriptive case series study. Setting: Department of Paediatric Nephrology, The Children’s Hospital & the Institute of Child Health, Multan. Period: From February 27, 2018 to February 27, 2019. Material and Methods: A total of 55 children, aged 1 to 10 years, diagnosed with SSNS, 1st presentation of NS (based on history) and who successfully completed 6 months steroid therapy, were enrolled. They were taught to check proteinuria at home by dipstick method and enter daily results on the follow up card provided from the Nephrology department of the hospital. The outcome variable, that is relapse, was noted on the Proforma. Results: Amongst 55 children, gender distribution showed 38 (69.1%) male and 17 (30.9%) females. Children with body weight <20 kg were 33 (60%) and those having ≥20kg were 22 (40%).  Patients with age <6 years were 54.5% and patients with age ≥6 years were 45.5%. Mean age was 5.93± 3.36 years. Frequency of relapse was noted to be 78.2% and patients who did not relapse within 1 year of completion of treatment were 21.8%. Conclusion: Nephrotic syndrome is a common presentation of childhood renal problems and is major cause of morbidity in our set up. Relapses are frequently associated with SSNS and most of the patients relapse within 1 year of completion of treatment. Relapses are more common in male children as compared to female children.

Background Steroid-sensitive nephrotic syndrome (SSNS) is a childhood disease with unclear pathophysiology and genetic architecture. We investigated the genomic basis of SSNS in children recruited in Europe and the biopsy-based North American NEPTUNE cohort.Methods We performed three ancestry-matched, genome-wide association studies (GWAS) in 273 children with NS (Children Cohort Nephrosis and Virus [NEPHROVIR] cohort: 132 European, 56 African, and 85 Maghrebian) followed by independent replication in 112 European children, transethnic meta-analysis, and conditional analysis. GWAS alleles were used to perform glomerular cis-expression quantitative trait loci studies in 39 children in the NEPTUNE cohort and epidemiologic studies in GWAS and NEPTUNE (97 children) cohorts.Results Transethnic meta-analysis identified one SSNS-associated single-nucleotide polymorphism (SNP) rs1063348 in the 3′ untranslated region of HLA-DQB1 (P=9.3×10−23). Conditional analysis identified two additional independent risk alleles upstream of HLA-DRB1 (rs28366266, P=3.7×10−11) and in the 3′ untranslated region of BTNL2 (rs9348883, P=9.4×10−7) within introns of HCG23 and LOC101929163. These three risk alleles were independent of the risk haplotype DRB1*07:01-DQA1*02:01-DQB1*02:02 identified in European patients. Increased burden of risk alleles across independent loci was associated with higher odds of SSNS. Increased burden of risk alleles across independent loci was associated with higher odds of SSNS, with younger age of onset across all cohorts, and with increased odds of complete remission across histologies in NEPTUNE children. rs1063348 associated with decreased glomerular expression of HLA-DRB1, HLA-DRB5, and HLA-DQB1.Conclusions Transethnic GWAS empowered discovery of three independent risk SNPs for pediatric SSNS. Characterization of these SNPs provide an entry for understanding immune dysregulation in NS and introducing a genomically defined classification.

Background and objective: Angiotensin-converting enzyme (ACE) insertion/deletion (I/D) gene polymorphism correlates with circulating and cellular ACE concentration. Association between ACE I/D gene polymorphism and steroid-sensitive nephrotic syndrome (SSNS) risk in children is still controversial. This meta-analysis was performed to evaluate the relation between ACE I/D gene polymorphism and SSNS susceptibility in children. Methods: The relevant investigations were screened from the search engines of PubMed, Cochrane Library and CBM-disc (China Biological Medicine Database) as of 1 March 2011, and eligible studies were synthesized using meta-analysis methods. Results: Ten studies were identified for the analysis of association between ACE I/D gene polymorphism and SSNS risk in children, including seven in Asians, one for Caucasians and two in Africans. There was no markedly positive association between D allele or DD genotype and SSNS susceptibility in Asians, Caucasians and Africans (D: Asians OR = 1.24, p = 0.28; Caucasians OR = 1.61, p = 0.15; Africans OR = 1.61, p = 0.53; DD: Asians OR = 1.72, p = 0.15; Caucasians OR = 1.39, p = 0.48; Africans OR = 1.80, p = 0.56). Furthermore, II homozygous seemed not to play a protective role against SSNS onset for Asians, Caucasians and Africans (Asians OR = 0.95, p = 0.85; Caucasians OR = 0.30, p = 0.11; Africans OR = 0.60, p = 0.65). Conclusions: There was no association between ACE I/D gene polymorphism and SSNS susceptibility in Asians, Caucasians and Africans. However, the conclusions for Caucasians and Africans were less powerful.

Abstract Background Serum adiponectin circulates in three multimeric isoforms: high-molecular-weight (HMW), middle-molecular-weight (MMW), and low-molecular-weight (LMW) isoforms. Potential change in the circulating adiponectin levels in patients with nephrotic syndrome (NS) remain unknown. This study aimed to assess the levels of total adiponectin and the distribution of its isoforms in pediatric patients with NS. Methods We sequentially measured total adiponectin and each adiponectin isoform levels at the onset of NS, initial remission, and during the remission period of the disease in 31 NS patients. We also calculated the ratios of HMW (%HMW), MMW (%MMW), and LMW (%LMW) to total adiponectin incuding 51 control subjects. Results The median of total serum adiponectin levels in patients were 36.7, 36.7, and 20.2 μg/mL at the onset, at initial remission, and during the remission period of NS, respectively. These values were significantly higher than those in control subjects. The median values of %HMW, %MMW, and %LMW values were 56.9/27.0/14.1 at the onset, 62.0/21.8/13.4 at the initial remission, and 58.1/21.7/17.5 at during the remission period of NS, respectively. Compared with control subjects, %HMW at initial remission and %MMW at the onset were high, and the %LMW values at the onset and at initial remission were low. Conclusions In patients with NS, total serum adiponectin levels increase at the onset of the disease, and the ratio of adiponectin isoforms changes during the course of the disease. Further studies are needed to delineate the mechanisms between proteinuria and adiponectin isoforms change.
