Case: 2 A 48-year-old woman comes to the emergency department due to worsening headache, blurred vision, and nausea for the past several days. She also has had decreased urine output. Medical history is significant for systemic sclerosis. Blood pressure is 190/110 mm Hg and pulse is 96/min. Physical examination shows diffuse skin thickening involving the hands, face, and anterior chest. There are no focal neurologic deficits, but a flame-shaped retinal hemorrhage is present. Laboratory studies reveal elevated serum blood urea nitrogen and creatinine levels, which were within normal limits during a recent office visit. Urine microscopy shows no sediment.

Case: 1 A 42-year-old man comes to the office due to hematuria, fatigue, and nasal congestion for the last few weeks. He has no chronic medical conditions. Blood pressure is 160/96 mm Hg. Physical examination shows edema around the ankles, hands, and face. Laboratory results reveal blood urea nitrogen of 40 mg/dL and serum creatinine of 3.8 mg/dL. Urinalysis shows moderate proteinuria and a large amount of red blood cells (RBCs) with RBC casts. A kidney biopsy is performed. Light microscopy reveals cellular proliferation, focal necrosis, and crescent formation of most of the glomeruli. On immunofluorescent microscopy, there are no immunoglobulin or complement deposits.
