Objective:
This systematic review and meta-analysis aimed to identify the risk factors for acute kidney injury (AKI) in patients with severe acute pancreatitis (SAP).
Methods:
A comprehensive literature search was conducted using the PubMed, Embase and Cochrane Library databases for case-control studies comparing the clinical characteristics of patients with SAP with and without AKI. The quality of the included studies was assessed using the Newcastle-Ottawa Scale (NOS). Pooled odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated using fixed- or random-effects models, based on heterogeneity.
Results:
Five studies involving 795 patients with SAP were included, of whom 173 (21.8 %) developed AKI. All studies were of high quality according to the NOS. Among the 17 potential risk factors that were analysed, a history of alcohol consumption (OR = 2.36, 95% CI = 0.54-10.43, p < 0.001), elevated serum amylase (OR = 4.50, 95% CI = 1.77-11.43, p = 0.002) and Acute Physiology and Chronic Health Evaluation II (APACHE II) score (OR = 1.57, 95% CI = 0.49-2.64, p = 0.004) were significantly associated with an increased risk of AKI. However, hypertension (OR = 1.14, 95% CI = 0.60-2.16, p = 0.69) and diabetes (OR = 1.88, 95% CI = 0.51-6.95, p = 0.34) were not significantly associated with AKI risk. Based on funnel plots, no obvious publication bias was detected.
Conclusions:
A history of alcohol consumption, elevated serum amylase and APACHE II score are significant risk factors for AKI in patients with SAP. For early intervention, clinical physicians should be vigilant about the risk of AKI in patients with SAP with these factors. More high-quality studies are needed to validate these findings and explore other potential risk factors.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
01:27Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
