Write answer in between .Q:A 55-year-old African American male presents to his primary care physician with complaints of persistent back pain and fatigue over 12 months. Physical examination reveals a blood pressure of 190150 mm Hg, and laboratory tests reveal hyperlipidemia and a serum creatinine level of 3.0 mgdL. 4.5 g of protein are excreted in the urine over 24 hours. Renal biopsy shows eosinophilic, acellular material in the glomerular tuft and capillary walls that display apple green-colored birefringence in polarized light upon Congo red tissue staining. The patient most likely suffers from which of the following:? A: Membranous nephropathy, B: Focal segmental glomerular sclerosis, C: Drug-induced acute tubular necrosis, D: Multiple myeloma, E: Malignant hypertension,  <response>: Based on the information provided in the question stem, the key findings are:- 55-year-old African American male - Persistent back pain and fatigue over 12 months- Hypertension blood pressure 190150 mm Hg- Hyperlipidemia- Elevated serum creatinine of 3.0 mgdL - Proteinuria of 4.5 g per 24 hours- Renal biopsy showing eosinophilic, acellular material in the glomeruli that stains with Congo red, indicating amyloid depositsThis constellation of findings - amyloidosis, proteinuria, elevated creatinine, and hypertension - is most consistent with a diagnosis of multiple myeloma. The amyloid deposits, back pain, fatigue, and proteinuria point towards multiple myeloma as the cause of kidney injury. The other answer choices can be ruled out based on the information provided.D: Multiple myeloma
