In the evaluation of patients older than 50 with severe back pain and chronic simple anemia, the diagnosis of multiple myeloma must be considered. Due to the age group affected, degenerative changes on spinal films may be misdiagnosed as osteoporosis, and anemia may be attributed to iron deficiency. These errors can be avoided in more than 99% of the cases of multiple myeloma by ordering a serum protein electrophoresis (SPE). Abnormal SPE patterns include monoclonal gammopathy and hypogammaglobulinemia. In the detection of multiple myeloma, magnetic resonance imaging has been found superior to plain radiograph, computed tomography and bone scan.

Intravenous iron is commonly prescribed for treatment of iron deficiency, with modern formulations demonstrating an acceptable safety profile in the majority of patients. We report the case of a patient who was hospitalised with muscle pain, deteriorating mobility and multiple fractures following repeated ferric carboxymaltose infusions. Investigations revealed severe hypophosphatemia with serum phosphate of 0.27 mmol/L, 25-hydroxyvitamin D (25OHD) level of 32 nmol/L and insufficiency fractures of the sacrum and L5 transverse process. The patient's hypophosphatemia was corrected with several infusions of intravenous phosphate, as well as oral phosphate and calcitriol, with subsequent resolution of her muscle aches, back pain and immobility. The risk of persistent hypophosphatemia and osteomalacia may be higher with iron carboxymaltose than other iron formulations and a transient increase in intact fibroblast growth factor-23 with reduced renal tubular phosphate absorption has been postulated as the key mechanism. This risk appears increased by repeated iron infusions, underlying malnutrition, hypophosphatemia at baseline, vitamin D deficiency, hyperparathyroidism or anti-resorptive medication use. The true risk and incidence of hypophosphatemia need to be clarified so that appropriate monitoring, prevention and treatment strategies can be developed.
