Abstract
Background: Nutcracker syndrome (NCS) has been reported to coexist with various glomerulonephritis (GN). This study investigated clinical features of NCS combined with GN in a pediatric case series and the possible relationship between these two conditions.
Methods: Clinical and pathologic findings of 15 children with NCS and biopsy-proven GN were analyzed. NCS was diagnosed with renal Doppler ultrasonography, abdominal computed tomography, and/or magnetic resonance imaging. Glomerular lesions were divided into two pathological categories: minor glomerular abnormalities (MGAs) and definite GN.
Results: Mean age of all patients was 11 ± 3.36 years and mean follow-up duration was 53.8 ± 29.3 months. Chief complaint was proteinuria with or without hematuria. During follow-up, five patients developed left kidney enlargement. Abnormal levels in immunological tests were revealed in 10 patients. Extrarenal symptoms including gonadal varicocele, splenic cyst, syncope, and anemia were found in seven patients. On kidney biopsy, seven patients had MGAs and eight children showed definite GN (one case of focal GN, one case of mesangial proliferative GN, one case of focal segmental glomerulosclerosis, two cases of immunoglobulin A [IgA] vasculitis nephritis, and three cases of IgA nephropathy). While the MGA group showed a higher proportion of isolated proteinuria and a lower estimated glomerular filtration rate (eGFR) at the last visit, there were no differences in age, clinical features of NCS, extrarenal symptoms, immunological tests, and eGFR decline rate between the two groups.
Conclusion: NCS may be associated with the presence of various GN. The causal relationship between NCS and GN should be further investigated.
期刊介绍：
Kidney Research and Clinical Practice (formerly The Korean Journal of Nephrology; ISSN 1975-9460, launched in 1982), the official journal of the Korean Society of Nephrology, is an international, peer-reviewed journal published in English. Its ISO abbreviation is Kidney Res Clin Pract. To provide an efficient venue for dissemination of knowledge and discussion of topics related to basic renal science and clinical practice, the journal offers open access (free submission and free access) and considers articles on all aspects of clinical nephrology and hypertension as well as related molecular genetics, anatomy, pathology, physiology, pharmacology, and immunology. In particular, the journal focuses on translational renal research that helps bridging laboratory discovery with the diagnosis and treatment of human kidney disease. Topics covered include basic science with possible clinical applicability and papers on the pathophysiological basis of disease processes of the kidney. Original researches from areas of intervention nephrology or dialysis access are also welcomed. Major article types considered for publication include original research and reviews on current topics of interest. Accepted manuscripts are granted free online open-access immediately after publication, which permits its users to read, download, copy, distribute, print, search, or link to the full texts of its articles to facilitate access to a broad readership. Circulation number of print copies is 1,600.
