AI Article Synopsis

  • Acute pancreatitis (AP) is an inflammatory condition with various causes, including drugs, which account for a small percentage of cases; diagnosing drug-induced AP is often complicated due to a lack of specific symptoms.
  • A study conducted at Hospital Universitari de Bellvitge analyzed 38 patients with suspected drug-induced AP from June 2007 to March 2023, revealing that most cases were linked to a single drug, with azathioprine and atorvastatin being the most common culprits.
  • The findings suggest that increased awareness and a proposed diagnostic algorithm may improve the identification and management of drug-induced pancreatitis, highlighting the need for drug assessment when diagnosing AP.

Article Abstract

Introduction: Acute pancreatitis (AP) is an inflammatory disease with multiple etiologies, and the emergence of complications. Between 0.1-5% of cases are attributed to drugs. The absence of specific characteristics complicates the diagnosis and treatment of drug-induced AP. Reviewing patients admitted with the diagnosis of drug-induced AP can provide information and improve its management.

Patients And Methods: This is a descriptive, observational, and retrospective study. All patients admitted to the Hospital Universitari de Bellvitge between June 2007 and March 2023 with suspected drug-induced AP were included. The data were obtained from the hospital pharmacovigilance program database.

Results: Thirty-eight patients with suspected drug-induced AP were identified, representing 0.62% of all adverse drug reactions (n=6.085). Of these, 65.8% (n=25) had a single suspected drug. The median latency period for the onset of adverse drug reactions was 160.5 days (IQR: 18-582 days), and the median hospital stay was 5 days (IQR: 3-7 days). Fifty-nine suspected drugs were identified, involving 26 active principles. Azathioprine and atorvastatin were the most frequent, with 9 cases each (15.2%), followed by enalapril with 8 cases (13.6%). Drug etiology was assessed in 23 cases (60.5%), and the suspected drug was discontinued in all cases. There was one fatal case documented (2.63%).

Conclusion: This study can contribute to better understanding of drug-induced pancreatitis episodes. We propose a diagnostic algorithm that includes the assessment of the drug as a possible cause.

Drug-induced emesis is one of the major symptoms of gastrointestinal toxicity. Preclinical risk assessment of emesis has been challenging owing to the lack of suitable animal models or in vitro assay systems. One of the triggers of emesis is an excessive serotonin (5-HT) release from enterochromaffin (EC) cells in the intestinal tract, which activates the vomiting center in the brain stem and elicits the vomiting reflex.

Article Synopsis
  • Everolimus, a drug for treating certain cancers, poses a risk of hepatitis B virus (HBV) reactivation and hepatitis, particularly in patients with current or past HBV infection.
  • A study involving 377 patients on everolimus found that 28.75% of those with active HBV (HBsAg-positive) and 17.85% of those without (HBsAg-negative) developed hepatitis, with higher risks associated with specific treatments and lack of prophylaxis.
  • The research emphasizes the need for HBV screening and careful liver function monitoring for patients receiving everolimus, especially in regions where HBV is common.

Article Synopsis
  • Midostaurin is the first targeted treatment for AML FLT3 and reduces mortality by 23% compared to standard chemotherapy, but it has side effects, especially gastrointestinal issues.
  • A case was reported where a patient experienced acute pancreatitis symptoms after starting midostaurin, including abdominal pain and elevated enzyme levels.
  • The patient was treated with IV hydration and anti-symptomatic care, recovering after four days, but drug-induced acute pancreatitis remains a rare and complicated diagnosis without established links to midostaurin despite various potential mechanisms.

Rectal 5-aminosalicylic acid induced pancreatitis in a patient with newly diagnosed ulcerative colitis.

Oral 5-aminosalicylic acid (5-ASA) are well recognised to have the potential to cause drug-induced acute pancreatitis; however, there have only been infrequent case reports of rectal formulations causing acute pancreatitis. We describe a case of rectal Mesalazine (a 5-ASA) induced acute pancreatitis. The patient was commenced on rectal 5-ASA therapy 8 weeks prior to presentation following a diagnosis of Montreal classification E1 Ulcerative Colitis on colonoscopy.
