Approach to the Patient with Glomerular Disease

Glomerular diseases of the kidneys are associated with a limited array of clinical syndromes, including asymptomatic hematuria and/or proteinuria, acute nephritis, nephrotic syndrome, rapidly progressive glomerulonephritis, and chronic glomerulonephritis. The specific diseases that underlie these syndromes are numerous and heterogeneous. Broadly, they may be divided into primary and secondary disorders depending on whether the kidneys are the sole organs affected or whether other organ systems are also involved in the disease processes. A systematic approach involving a careful history, physical examination, assessment of renal function, and urinalysis (composition and microscopy) and protein excretion, combined with biochemical and serologic testing, can provide important clues to diagnosis and prognosis. Renal biopsy is often required for a complete and accurate diagnosis as well as a prognosis and therapeutic decision making.
