저자들은 IgG, kappa 다발골수종 환자에서 설명되지 않는 고인산혈증이 있어 가성고인산혈증을 의심하고 sulfosalicylicacid를 이용하여 환자의 혈청에서 단백질을 제거 후 다시 인을 측정하여 정상 인 수치를 보인 1예를 경험하였으므로 문헌고찰과 함께 보고하는 바이다.
Hyperphosphatemia develops when there is impaired renal phosphate excretion or massive extracellular fluid phosphate load. For example, renal insufficiency, hypoparathyroidism, exogenous phosphate administration, and extensive cellular injury induce a hyperphosphatemic state. In patients with multiple myeloma, renal insufficiency occurs as a result of hypercalcemia, light chain tubulopathy, urate nephropathy or infection, and hyperphosphatemia usually results from renal failure. We report here a case of a patient with multiple myeloma who had an elevated serum phosphate level measured by the phosphomolybdate UV method without significant renal insufficiency and was finally diagnosed with pseudohyperphosphatemia.
