laboratory parameters (white blood cell count,neutrophil count, lymphocyte count, hemoglobin level, platelet level, red cell distribution width (RDW) level, hematocrit (HCT), renal function, hepatic function, electrolytes, arterial blood gas, HOMA-IR) will be assessed and imaging: Abdominal ultrasonography, Abdominal CT or MRI if needed

1. Homeostatic model assessment of insulin resistance it measure severity of insulin resistance, there is an association between insulin resistance and severity of acute pancreatitis.

   It is defined as fasting glucose (mmol/L) × fasting insulin (μmol/L)/22.5] or [fasting glucose (mg/dL) × fasting insulin (μmol/L) Reference index levels is ≤ 2. If index ˃ 2 indicate presence of insulin resistance

2. The harmless acute pancreatitis score Harmless acute pancreatitis score contains three parameters - blood urea nitrogen, levels of serum creatinine and haematocrit . The patient is classified as harmless acute pancreatitis score negative (-) if they have blood urea nitrogen <25 mg/dL, serum creatinine levels < 2 mg/dL, and haematocrit levels of <43% for males and <39.6% for females at the time of admission. The patient is considered positive (+) if any one of the above parameters is positive.](streamdown:incomplete-link)
