[Asymptomatic nephritis in relatives living with children with acute poststreptococcal glomerulonephritis]
Insights
Poststreptococcal glomerulonephritis can affect asymptomatic individuals living with infected children. Early detection and eradication of streptococcal infections are crucial to prevent potential chronic nephritis development.
Area of Science:
- Nephrology
- Infectious Diseases
- Pediatrics
Context:
- Poststreptococcal glomerulonephritis (PSGN) is a common kidney disease in children.
- Identifying asymptomatic carriers is vital for controlling disease spread and preventing complications.
- This study investigated household contacts of children diagnosed with PSGN.
Purpose:
- To determine the prevalence of asymptomatic urinary abnormalities and streptococcal infections in household contacts of PSGN patients.
- To assess the risk of developing chronic nephritis in these contacts.
- To emphasize the importance of early detection and streptococcal infection eradication.
Summary:
- A study of 114 household contacts of PSGN patients revealed significant findings.
- 31% exhibited increased urinary erythrocytes, indicating kidney involvement.
- 71% had elevated antistreptolysin O titers, suggesting recent streptococcal exposure, while 9% tested positive for beta-hemolytic streptococci.
Impact:
- Highlights the need for screening asymptomatic household contacts of PSGN patients.
- Underscores the potential for developing chronic nephritis in undiagnosed individuals.
- Reinforces the importance of eradicating streptococcal infections to prevent PSGN and its sequelae.
Abstract:
We studied a group of 114 persons living together with children admitted in the hospital because of poststreptococcal glomerulonephritis; minute count of the urinary sediment, antistreptolysin 0 and throat culture were done. An increased was found in the urinary excretion of erythrocytes in 31% of the population studied; 71% showed a rise of serum antistreptolysin 0 and 9% showed beta hemolytic streptococci in their throat culture. It is important to search for these asymptomatic patients among relatives and follow their course; there is a possibility that some will developed chronic nephritis. It is also important to erradicate the streptococcal infection.
