ABSTRACT
OBJECTIVES: The relative rarity of hypertriglyceridemia (HTG) as the etiology for acute pancreatitis (AP) delays the final diagnosis of hypertriglyceridemia-induced AP (HTG-AP). This study aimed to explore the diagnostic and prognostic value of pseudohyponatremia in this clinical entity. METHODS: We retrospectively compared 140 patients with HTG-AP and 266 patients of AP of other etiologies. The correlation of presenting hyponatremia and a final diagnosis of HTG-AP is evaluated. RESULTS: Presenting hyponatremia had an area under curve of 0.926 for predicting the diagnosis of HTG-AP. After dichotomization by the optimal cutoff value of 130 mEq/dL, patients with hyponatremia had a higher prevalence of acute kidney injury (61.9% vs 38.1%, P < 0.001), systemic inflammatory response syndrome (52.2% vs 47.8%, P < 0.001), a higher Ranson criteria (3.0 vs 1.4, P < 0.001), and a higher Bedside Index for Severity of Acute Pancreatitis score (0.69 vs 0.55, P = 0.011). CONCLUSIONS: Presenting hyponatremia is highly efficient in differentiating hypertriglyceridemia from other etiologies of AP. It also demonstrated promising prognostic values in both AP and HTG-AP patients. Therefore, initial serum sodium could potentially provide the first clue of HTG-AP, as well as facilitate risk-stratifying patients to determine treatment allocation.

OBJECTIVES: Concurrent diabetic ketoacidosis (DKA) is highly prevalent in patients with hypertriglyceridemia-induced pancreatitis (HP). Diabetic ketoacidosis could potentially complicate the diagnosis, management, and prognosis of HP. This study aimed to directly compare the clinical course of HP with and without DKA and assess the outcomes of frequently used severity-prediction scores in such population. METHODS: We retrospectively analyzed 140 patients with HP; 37 patients (26.4%) had concurrent DKA. We compared epidemiologic characteristics, initial laboratory values, and clinical courses between the DKA and non-DKA groups. Bedside Index for Severity in Acute Pancreatitis score, Sequential Organ Failure Assessment score, Ranson criteria, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Marshall score were calculated and compared between groups. RESULTS: We observed more acute kidney injury in the DKA group. Patients with DKA more likely required intensive care unit admission, received intravenous insulin, and were discharged on subcutaneous insulin. Ranson criteria and APACHE II score were significantly higher with DKA. CONCLUSIONS: Concurrent DKA does not affect length of stay, in-hospital mortality, and readmission rate in patients with HP. Higher Ranson criteria and APACHE II score likely reflected derangement of clinical parameters secondary to DKA rather than true severity of pancreatitis in such population.
