Treatment of acute hypercalcemia

Area of Science:

• Nephrology
• Endocrinology
• Internal Medicine

Background:

• Acute hypercalcemia is a rare, potentially fatal electrolyte disturbance.
• It can manifest as a new onset or decompensation of chronic hypercalcemia.
• Symptoms are often mild and non-specific, affecting multiple organ systems.

Purpose of the Study:

• To outline the critical management steps for hypercalcemic crisis.
• To emphasize the importance of early recognition and evidence-based treatment.
• To highlight diagnostic considerations for underlying causes.

Main Methods:

• Initial supportive care and ABC assessment to stabilize vital functions.
• Utilizing severity index criteria for patient admission assessment.
• Monitoring neurological status and vital parameters (blood pressure, pulse, oxygen saturation, temperature).

Main Results:

• Key treatment strategies include restoring normovolemia, enhancing renal calcium excretion, and considering dialysis.
• Bisphosphonates are the primary pharmacologic agents post-hydration.
• Less commonly used agents include calcitonin, gallium nitrate, and mithramycin.

Conclusions:

• Effective management requires a multi-faceted approach addressing volume status, renal function, and calcium resorption.
• Prompt diagnosis and treatment guided by evidence-based principles are essential.
• Initiating a diagnostic workup for the underlying cause is critical for long-term management.
