Abstract
OBJECTIVE
Phosphate is crucial for cellular repair after injury and may be important in recovery following acute pancreatitis (AP). This study aimed to evaluate the association between hypophosphatemia and severity of AP.
METHODS
Patients admitted with AP between 2014-2018 were identified and their records were retrospectively reviewed. Pancreatitis severity was defined using the modified Atlanta Criteria. Hypophosphatemia was defined as phosphate <2 mg/dL and was assessed at three time points: within one day, within two days, at any time during admission. The proportion of patients who developed severe AP was compared between patients with and without hypophosphatemia.
RESULTS
Of 312 patients, 30.1% (n = 94) developed severe AP. Hypophosphatemia occurred in 25.0% overall, within one day in 19.7%, and within two days in 20.0%. A higher proportion of patients with hypophosphatemia developed severe AP (overall: 47.4% vs. 24.4%, P < 0.001; one day: 47.4% vs. 23.9%, P = 0.004; two days: 42.9% vs. 24.5%, P = 0.01). Patients with hypophosphatemia within one day were also more likely to have ICU admission ( P < 0.001) and longer length of stay ( P < 0.001).
CONCLUSIONS
Early hypophosphatemia during an admission for AP was associated with increased AP severity, ICU admission, and longer length of stay.
