Abstract
Some infections can be the cause of secondary nephrotic syndrome. The
aim of this study was to describe the experience of a Renal Disease Reference
Clinic from Central Brazil, in which serological markers of some infectious
agents are systematically screened in children with nephrotic syndrome. Data
were obtained from the assessment of medical files of all children under fifteen
years of age, who matched nephrotic syndrome criteria. Subjects were tested for
IgG and IgM antibodies against T. gondii and cytomegalovirus;
antibodies against Herpes simplex, hepatitis C virus and HIV; and surface
antigen (HBsAg) of hepatitis B virus. The VDRL test was also
performed. 169 cases were studied. The median age on the first visit was 44
months and 103 (60.9%) patients were male. Anti-CMV IgG and IgM
were found in 70.4% and 4.1%, respectively. IgG and IgM against
Toxoplasma gondii were present in 32.5% and 5.3%,
respectively. Two patients were positive for HBsAg, but none showed markers for
HIV, hepatitis C, or Treponema pallidum. IgG and IgM against
herpes simplex virus were performed on 54 patients, of which 48.1% and
22.2% were positive. IgM antibodies in some children with clinical signs of
recent infection suggest that these diseases may play a role in the genesis of
nephrotic syndrome.
