Clinicopathological Analysis on Hepatitis B Virus-Associated Glomerulonephritis in Children / 实用儿科临床杂志

ABSTRACT

Objective To investigate the clinicopathological features of hepatitis B virus-associated glomerulonephritis(HBV-GN) in children.Methods Clinical and pathological features were analyzed and correlated in 73 cases with renal biopsy-confirmed(HBV-GN).Sixty-six boys and 7 girls aged from 1 to 14 years old were included in this study,accounting for 14.4% in children under-(going) renal biopsy in the same period.Results Nephrotic syndrome(NS) was the prodominant clinical manifestation(53/73,72.6%),followed by glomerulonephritis(15/73,20.5%) and hematuria with proteinuria(5/73,6.9%).Serologic markers of HBV were found in all cases.Among them,55 cases(75%) were positive for hepatitis B surface antigen(HBsAg),hepatitis B e antigen(HBeAg) and anti-hepatitis B core(anti-HBc),14 cases(19.2%)positive for HBsAg,anti-HBe and anti-HBc,2 cases positive for HBsAg and anti-HBc,1 child positive for HBsAg and HBeAg,and another only positive for anti-HBc.The most common pathological type of HBV-GN was membranous nephropathy(MN),which was found in 69 cases(94.5%),followed by membranoproliferative glomerulonephritis(MPGN) and mesangial proliferative glomerulonephritis(MsPGN),2 cases(2.7%),respectively.All cases with NS presented themselves with MN.The pathological grades were significantly correlated with clinical manifestations through double trend analysis(?~2=5.22 P=0.022).Conclusions MN is predominant in childhood HBV-GN,which mainly presented with NS.Their clinical patterns are somewhat correlated with pathological grades.
