What condition is most likely diagnosed in a patient presenting with acute onset hematuria and facial edema after a sore throat?

• A. Acute poststreptococcal glomerulonephritis
• B. Idiopathic hematuria
• C. Immunoglobulin A nephropathy
• D. Minimal change disease

Answer: (A)

The condition most likely diagnosed in this scenario is acute poststreptococcal glomerulonephritis. This condition frequently follows a streptococcal throat infection, typically presenting with symptoms such as hematuria (the presence of blood in the urine) and edema (swelling due to fluid retention), which can manifest as facial swelling, especially around the eyes. Acute poststreptococcal glomerulonephritis occurs when the immune system reacts to the antigens from the streptococcus bacteria, leading to inflammation of the glomeruli in the kidneys. This inflammation compromises the kidney's ability to filter blood effectively, resulting in hematuria and edema. The timing of symptoms following the sore throat provides a strong clinical clue linking the infection to the kidney condition. While the other conditions listed may also involve hematuria or edema, they do not typically present in the acute context following a sore throat, making acute poststreptococcal glomerulonephritis the most likely diagnosis in this case.
