Insights
Early diagnosis of asparaginase-associated pancreatitis (AAP) in children with acute lymphoblastic leukemia (ALL) is crucial. Elevated serum elastase-1 levels can aid in early AAP detection, even with normal amylase, guiding timely treatment.
Area of Science:
- Oncology
- Pediatrics
- Gastroenterology
Background:
- L-asparaginase (L-asp) is a vital chemotherapeutic agent for pediatric acute lymphoblastic leukemia (ALL).
- A significant complication of L-asp therapy is asparaginase-associated pancreatitis (AAP).
- Early diagnosis of AAP is challenging with standard diagnostic markers.
Purpose of the Study:
- To highlight the utility of serum elastase-1 in the early diagnosis of asparaginase-associated pancreatitis (AAP) in pediatric ALL patients.
- To present cases where elastase-1 identified AAP before significant elevations in other pancreatic enzymes.
- To advocate for the inclusion of elastase-1 measurement in monitoring L-asp treated patients.
Main Methods:
- Case report presentation of two pediatric patients with ALL treated with L-asparaginase.
- Monitoring of serum pancreatic enzymes, including amylase, lipase, and elastase-1.
- Correlation of enzyme levels with the development of clinical symptoms suggestive of pancreatitis.
Main Results:
- Both cases demonstrated elevated serum elastase-1 levels indicative of pancreatitis.
- Serum amylase levels remained within normal limits in both patients during the early phase of pancreatitis.
- Early identification of AAP was achieved through elastase-1 measurement, facilitating prompt management.
Conclusions:
- Serum elastase-1 is a sensitive and potentially early marker for asparaginase-associated pancreatitis (AAP) in pediatric ALL.
- Routine monitoring of elastase-1 alongside amylase and lipase is recommended for L-asp-treated patients.
- Early diagnosis and intervention for AAP can improve patient outcomes and mitigate treatment-related toxicities.
Abstract:
L-asparaginase (L-asp) is a well-known anticancer agent used in the treatment of acute lymphoblastic leukemia (ALL) in children. However, it is also known to induce several acute complications, such as acute pancreatitis. This is a presentation of two pediatric acute lymphoblastic leukemia (ALL) cases of asparaginase-associated pancreatitis (AAP) diagnosed at an early stage based on elevated serum elastase-1 levels, in the presence of normal serum amylase levels. Early diagnosis and treatment of AAP, although imperative, is occasionally difficult if only standard diagnostic procedures are followed. Elastase-1 is a potentially useful marker for the early diagnosis of AAP. Therefore, the measurement of elastase-1 levels, in addition to amylase and lipase levels, is recommended in L-asp-treated patients.

Acute 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.
