Answer

In a few hospitalized patients, the initial injury is so severe that either persistent renal failure or progressive renal failure ensues. However, histologic regression of the disease in most patients is predictable, and the ultimate prognosis is good.

Although clinical resolution occurs in most patients, several authors report time-related reduction in precise measurements of renal function, as well as diminished renal functional reserve. These studies further support the thesis that any significant loss of nephrons leads to hyperfiltration of the remaining units. Studies that have followed up children with APSGN for 10-20 years have shown that approximately 20% of the patients have abnormal urine analyses, with less than 1% having azotemia. [40]
