ABSTRACT
The Nutcracker syndrome refers to compression of the left renal vein between the aorta and superior mesenteric artery, which results in renal vein and left gonadal vein varices, hematuria, and left flank pain. Here, we report a case of biopsy-proven membranoproliferative glomerulonephritis with radiologically documented Nutcracker syndrome. The patient presented with generalized edema for several months. In order to evaluate isomorphic hematuria, we performed computed tomography (CT), which showed Nutcracker syndrome. A renal biopsy revealedmembranoproliferative glomerulonephritis, Type I. In conclusion, inadults with Nutcracker syndrome that involves severe proteinuria, the possibility of combined glomerulonephritis must be considered.

BACKGROUND: It is well known that chronic hepatitis B virus infection can commonly cause membranous nephropathy (MN), membranoproliferative glomerulonephritis type I (MPGN I), and rarely, membranoproliferative glomerulonephritis type III (MPGN III), which has the combined pathologic findings of MN and MPGN I. We report the clinical findings of MPGN III in patients with positive serum hepatitis B virus surface antigen. METHODS: The clinical findings of six MPGN III patients were investigated retrospectively to compare with those of eight MN and nineteen MPGN I patients with positive serum hepatitis B virus antigen. RESULTS: The mean age of MPGN III cases (29.7 years) was younger than that of MN (43.7 years) and MPGN I cases (44.4 years)(p<0.05). Males were predominant in all groups and the male/female ratio was 6:0 in MPGN III, 6:2 in MN, 17:2 in MPGN I group. The cases of nephrotic range proteinuria (4 out of 6 (66.7%) in MPGN III and 6 out of 8 (75%) in MN group) were more frequent than the 5 out of 19 (26.3%) found in the MPGN I group (p<0.05). The cases of HBe antigenemia were 5 out of 6 (83.3%) in MPGN III, 16 out of 19 (84.2%) in MPGN I and 5 out of 8 (62.5%) in the MN group. The cases of increased SGOT level were 5 out of 6 (83.3%) in MPGN III, 14 out of 19 (73.7%) in MPGN I and 4 out of 8 (50%) in the MN group. The cases of increased SGPT level were 5 out of 6 (83.3%) in MPGN III, 10 out of 19 (52.6%) in MPGN I and 2 out of 8 (25%) in the MN group. The cases of decreased serum C3 level were 4 out of 6 (66.7%) in MPGN III, 13 out of 19 (68.4%) in MPGN I and 3 out of 8 (37.5%) in the MN group. CONCLUSION: Patients with MPGN III show similar clinical findings to both the nephrotic proteinuria of MN patients and the decreased serum C3 level and increased SGOT/SGPT of MPGN I patients.
