What is the typical latent period for postinfectious glomerulonephritis following pharyngitis?

• A. 5 days
• B. 10 days
• C. 14 days
• D. 3 weeks

Answer: (B)

Postinfectious glomerulonephritis is commonly associated with prior infections, particularly those caused by certain strains of Streptococcus bacteria following pharyngitis. The latent period refers to the time interval between the initial infection and the onset of glomerulonephritis symptoms. In adults and children, the typical latent period for postinfectious glomerulonephritis following a streptococcal infection, especially after pharyngitis, is approximately 10 days. During this time, the immune response is triggered, leading to the subsequent development of glomerulonephritis due to the formation of immune complexes that deposit in the kidneys. Understanding this timeline is crucial for clinicians in diagnosing and managing postinfectious glomerulonephritis, enabling them to correlate a patient's recent history of upper respiratory infections with the potential for developing renal complications. A longer period, such as 3 weeks, is generally not consistent, as most patients begin to show symptoms within the 10-day range following the infection.
