Calcium is pivotal for neuromuscular function, coagulation, and signal transduction. An imbalance of enteral calcium uptake, deposition in and resorption from bones, and renal calcium elimination causes hypercalcemia. ⋯ Knowing the actions of the CaSR is important for diagnosing and treating patients with hyperparathyroidism. Diuretics can cause hypercalcemia, but also provide a clinical tool to lower serum calcium.

Glomerulonephritis, secondary to bacterial, or, more rarely, viral or parasitic infections, is called infection-associated. The epidemiology of infection-associated glomerulonephritis has changed in recent decades. ⋯ The clinical manifestations of APGN and SAGN are different: APGN typically presents with a glomerulonephritis after an infectious latency period (post-infectious), while SAGN typically shows an immune complex glomerulonephritis concomitant with infection (para-infectious). SAGN often presents with an occult infections in older patients with multiple comorbidities.
