    ABSTRACT: Background/Aim: The effects of ω-3 fatty acids (O3FAs) on renal function and proteinuria in immunoglobulin A nephropathy (IgAN) are not fully understood. Thus, we conducted an up-to-date meta-analysis of the currently available randomized controlled trials (RCTs) to validate the effects of O3FA in IgAN. Methods: A literature search was performed in PubMed, Medline, Embase and the Cochrane Central Registry of Controlled Trials using an extended search strategy to identify RCTs that assessed the treatment efficacy of O3FA in IgAN. The dose-effect relationships of O3FA on renal function and proteinuria were also determined. Results: Five RCTs with a total of 233 patients were included in our analysis. Our results demonstrated that while O3FA does not have any beneficial effects in preserving renal function in IgAN, proteinuria was significantly reduced. Furthermore, patients who received a high dose of O3FA (>3 g/day) did not differ from those who received a low dose of O3FA (≤3 g/day) in renal function or proteinuria. Conclusion: The currently available evidence suggests that O3FA has no benefit in preserving renal function, but can ameliorate proteinuria in IgAN. However, the effects of O3FA on proteinuria are not dose dependent.

    ABSTRACT: To determine if glucocorticoids can prevent renal scar formation after acute pyelonephritis in pediatric patients. Patients younger than 16 years diagnosed with their first episode of acute pyelonephritis with a high risk of renal scar formation (ie, inflammatory volume ≥ 4.6 mL on technetium-99m-labeled dimercaptosuccinic acid scan [DMSA] or abnormal renal ultrasonography results) were randomly assigned to receive either antibiotics plus methylprednisolone sodium phosphate (1.6 mg/kg per day for 3 days [MPD group]) or antibiotics plus placebo (placebo group) every 6 hours for 3 days. Patients were reassessed by using DMSA 6 months after treatment. The primary outcome was the development of renal scars. A total of 84 patients were enrolled: 19 in the MPD group and 65 in the placebo group. Patient characteristics were similar between the 2 groups, including the acute inflammatory parameters and the initial DMSA result. Renal scarring was found in 33.3% of children treated with MPD and in 60.0% of those who received placebo (P < .05). The median cortical defect volumes on follow-up DMSA were 0.0 mL (range: 0-4.5 mL) and 1.5 mL (range: 0-14.8 mL) for the MPD and placebo groups, respectively (P < .01). Patients in the MPD group experienced faster defervescence after treatment than the placebo group. Adjunctive oral MPD therapy reduced the occurrence and/or severity of renal scarring after acute pyelonephritis in these hospitalized children who had a high risk of renal scar formation.

    ABSTRACT: We correlated abnormal findings on renal ultrasonography (US) and inflammatory volume (Volume) on technetium dimercaptosuccinic acid renal single photon emission computerized tomography (DMSA) in children with acute pyelonephritis (APN) with renal scars. A total of 31 males and 14 females (9 days to 9.8 years old) who fulfilled diagnostic criteria for APN and who underwent initial DMSA between January 1995 and July 2002 and followup DMSA at least 6 months later were enrolled in the study. APN was diagnosed by initial DMSA, and placement in the scar or scar-free group was determined by followup DMSA. Photopenic areas on initial DMSA were calculated as Volume, and were compared to US findings. Ultrasound demonstrated 35 abnormal kidneys (38.9%) among these children with APN. Significant differences in age, Volume (11.19 +/- 2.52 ml vs 3.02 +/- 0.75 ml, p <0.005), C-reactive protein (CRP) and photopenic lesion on initial DMSA were found between children with abnormal and normal US. Of 65 children with initial APN foci 33 (50.8%) recovered, and the others had development of scars. The sensitivity of US for detecting APN (identified by DMSA scan) was 49.2%, and the specificity was 88% (OR 7.1, 95% CI 2.18 to 24.41). The sensitivity of US for predicting renal scarring was 59.4%, and the specificity was 60.6% (OR 2.3, 95% CI 0.82 to 7.65). Patients with abnormal US findings and high serum CRP (greater than 70 mg/l) had a large Volume (10.96 +/- 3.05 ml) and a 76.2% chance of being in the scar group. US findings are significantly correlated to Volume in APN. Along with a high level of CRP, US is helpful in predicting development of renal scarring.
