Which condition is suggested by acute renal insufficiency, hematuria, proteinuria, hemoptysis in a young male patient?

The combination of acute renal insufficiency, hematuria, proteinuria, and hemoptysis in a young male patient is highly suggestive of Goodpasture syndrome. This condition is characterized by the presence of anti-glomerular basement membrane antibodies, leading to crescentic glomerulonephritis and pulmonary hemorrhage. The acute renal failure is a result of significant glomerular damage, while the hemoptysis indicates involvement of the lungs, a hallmark of this syndrome.

In Goodpasture syndrome, individuals often present with these symptoms due to the simultaneous attack on renal and pulmonary tissue. The acute renal insufficiency arises from rapid loss of kidney function, while hematuria and proteinuria are typical findings in glomerular diseases due to damage to the glomerular capillary barrier. The presence of hemoptysis further supports the diagnosis since it suggests the involvement of lung tissue, which is often affected in this condition due to the presence of the same antibodies.

Other conditions with similar renal symptoms might not typically present with pulmonary manifestations. For example, minimal change disease primarily causes nephrotic syndrome in children without significant hemoptysis. IgA nephropathy usually presents with episodic hematuria often associated with
