In a nested-case control study of 100 cases of gastric cancer and 400 matched controls in relation to virulence factors of Helicobacter pylori in a Korean cohort, CagA seropositivity was significantly associated with a higher risk of gastric cancer among H. pylori-infected subjects (OR=3.57, 95% CI 1.05–12.14).
X-linked nephrogenic diabetes insipidus (NDI) is a rare disease caused by mutations in the vasopressin V2 receptor (AVPR2) gene. We analyzed the AVPR2 gene in 6 unrelated Korean families with X-linked NDI, and found 6 novel mutations. Two of them were missense point mutations, 2 were short deletions causing frameshifts, 1 was a duplication of 9 bases, and 1(More)
Studies have suggested that lipids participate in the pathogenesis of chronic progressive glomerulosclerosis. To examine the frequency of intraglomerular lipid deposition in routine biopsies, renal biopsy material from 631 consecutive patients with glomerular lesions was studied by light, electron, and immunofluorescence microscopy. Fifty-three patients(More)
The pathogenic role of the hepatitis B virus (HBV) infection for glomerulonephritis (GN) is not clear. The frequency of HBsAg has been studied in sera of 732 consecutive patients who have glomerular diseases by using radioimmunoassay. The frequency of HBs antigenemia was 11.9%, which was not different from that in the general population of South Korea. Of(More)
Between June 1975 and March 1987, 662 renal biopsies were performed in 657 children at Seoul National University Children's Hospital. Nephrotic syndrome was the most indication for renal biopsy and accounted for 62% of all cases. Of these, 57% showed minimal change lesions and 21% showed focal segmental glomerular sclerosis. Nephropathy, associated with(More)
Intestine is seldom a site of clinical manifestation of malignant hypertension, particularly in childhood. This report deals with a case of malignant nephrosclerosis superimposed on benign nephrosclerosis which probably resulted from a unilateral obstructive uropathy and chronic pyelonephritis. Clinical features included severe hypertension,(More)
Background:Few cohort studies have investigated Epstein–Barr virus (EBV) infection before the occurrence of gastric cancer.Methods:Among 14 440 cohort participants, 100 incident gastric cancer cases were individually matched to two controls. Epstein–Barr virus antibodies IgG and IgA against viral capsid antigen (VCA), EBV nuclear antigen (EBNA) antibody(More)
