Explain the pathological consequences of refeeding syndrome [3]
:
Shift from Fat to Carbohydrate Metabolism:
* In refeeding syndrome, the reintroduction of carbohydrates leads to a shift from fat to carbohydrate metabolism. This switch activates insulin secretion, which in turn increases cellular uptake of glucose.
Intracellular Movement of Phosphate:
* Insulin and increased glucose uptake stimulate the intracellular movement of phosphate, which is used in the synthesis of ATP and 2,3-diphosphoglycerate in erythrocytes. This intracellular shift reduces serum phosphate levels.
Decreased Phosphate Stores:
- Patients with chronic malnutrition often have depleted phosphate stores, although their serum phosphate levels may initially be normal. When refeeding starts, the sudden demand for phosphate in anabolic processes exceeds the supply, leading to hypophosphatemia.
Describe the clinical consequences of hypophosphatemia (e.g. caused by refeeding syndrome) [5]
Cardiac Dysfunction: Hypophosphatemia can impair myocardial contractility, leading to heart failure. It may also cause arrhythmias due to its role in maintaining normal cellular electrophysiology.
Respiratory Failure: Phosphate is essential for ATP production, necessary for respiratory muscle function. Severe hypophosphatemia can lead to muscle weakness, including the diaphragm and intercostal muscles, potentially resulting in acute respiratory failure.
Neurological Complications: These can range from confusion and seizures to coma, attributable to disturbed ATP metabolism in the central nervous system.
Haematological Effects: Reduced 2,3-diphosphoglycerate levels in erythrocytes affect oxygen release from haemoglobin, leading to tissue hypoxia. Hypophosphatemia can also result in hemolysis.
Rhabdomyolysis: Phosphate depletion impairs ATP production in muscles, which can lead to muscle breakdown and rhabdomyolysis.
Patients are considered high-risk of refeeding syndrome if they if one or more of the following..? [4] or two of more the following..? [4]
One of:
- BMI < 16 kg/m2
- unintentional weight loss >15% over 3-6 months
