Drug-Induced Pancreatitis

[Pancreatitis from drugs-Drugs for treatment of pancreatitis]

BACKGROUND

Drugs are a rare but important cause of acute pancreatitis (AP) due to potential therapeutic consequences, accounting for up to 5% of all cases of AP. The diagnosis of drug-induced AP is challenging due to mostly weak evidence and complex diagnostic criteria.

OBJECTIVE

This review article defines drug-induced AP, summarizes the evidence for drugs associated with AP and highlights the challenges in the diagnosis of this condition. The second part of the article focuses on the main pillars of AP treatment.

CURRENT DATA

The association of most drugs associated with AP is based on case reports and case series but there are no high-quality studies. There is sufficient evidence of a causal relationship for only 40 of more than 500 drugs associated with AP and for almost none of the drugs the causal mechanism has been definitively clarified. Several classification systems and criteria have been proposed to assess whether a drug causally triggers AP, with criteria including the temporal association, the exclusion of other causes and recurrence of AP after re-exposure.

CONCLUSION

The diagnosis of drug-induced AP remains a challenge, with many common drugs being incorrectly associated with AP. There is an urgent need for the development of biomarkers to facilitate the diagnosis of drug-induced AP. Drug treatment for AP is still primarily a needs-based fluid management and efficient analgesia. New and causal therapeutic approaches need clinical validation.

Pancreatitis associated with BRAF inhibitors: a disproportionality analysis based on the Food and Drug Administration Adverse Event Reporting System

BACKGROUND

The relationship between the development of pancreatitis and the use of BRAF (B-Raf proto-oncogene, serine/threonine kinase) inhibitors remains incompletely understood, primarily due to the infrequency of such cases.

AIM

This study aimed to investigate the association between BRAF inhibitors and pancreatitis, and to describe the clinical characteristics of pancreatitis related to these agents.

METHOD

A disproportionality analysis was conducted using data from the Food and Drug Administration Adverse Event Reporting System between July 2011 and June 2024. The reporting odds ratio (ROR) and information component (IC) were employed to assess the association between BRAF inhibitors and pancreatitis. Additionally, subgroup analysis and time-to-onset analysis were further performed.

RESULTS

A total of 169 cases of pancreatitis were identified in association with BRAF inhibitors: 71 cases with vemurafenib, 63 with dabrafenib, and 35 with encorafenib. The median age of patients was 62 years. Vemurafenib, dabrafenib, and encorafenib all showed a positive signal for pancreatitis, with respective RORs and ICs as follows: vemurafenib (ROR 2.46, 95% CI 1.95-3.10; IC = 1.27, 95% CI 0.88-1.56), dabrafenib (ROR 1.56, 95% CI 1.22-2.00; IC = 0.63, 95% CI 0.21-0.93), and encorafenib (ROR 2.59, 95% CI 1.86-3.62; IC = 1.34, 95% CI 0.77-1.74). The shortest median time-to-onset for pancreatitis was observed with vemurafenib (6.5 days), followed by encorafenib (14.0 days) and dabrafenib (129.5 days).

CONCLUSION

This study reveals a significant reporting association between BRAF inhibitors and the development of pancreatitis, with a higher risk observed in the early stage of treatment.

Drug-induced pancreatitis: a real-world analysis of the FDA Adverse Event Reporting System and network pharmacology

Background

Drug-induced pancreatitis is a rare disease but frequently reported, owing to the vast number of medications.

Aim

To summarize potential drugs causing pancreatitis and to speculate on underlying mechanisms.

Methods

We extracted more than 60,000 reports of pancreatitis submitted to the U.S. Food and Drug Administration Adverse Event Reporting System (January 2004 to March 2023). Data on patient age, sex, weight, time to onset, and outcome (death et al.) were collected. Disproportionality analysis was used in data mining to identify associations between drugs and pancreatitis events. Seven databases, commonly used for network pharmacology analysis, were searched to identify potential targets.

Results

Of 867 drugs with 3 or more reports, 101 drugs met all criteria using disproportionality analysis and indicated a potential risk of pancreatitis. The risk of 40 drugs had not been previously noted in "UpToDate" database. Patients taking the drugs had a similar sex distribution, were mostly 45-64 years old, and were heavier (median, 88 kg; P < 0.0001). The median time to onset was 199 days (interquartile range, 27-731.5). Ponatinib (16.48%), tigecycline (14.12%) and valproic acid (13.41%) had higher fatality rates. Potential targets related to pancreatitis were identified in 50 of the 101 drugs.

Conclusion

Clinicians providing the 101 drugs for treatment should stay vigilant to detect pancreatitis early.

Splenic Infarctions and Sepsis Secondary to Ceftriaxone-Associated Acute Pancreatitis: A Case of Interdisciplinary Collaboration

The spleen plays a crucial role in filtering aging blood cells and defending against encapsulated microorganisms. While not essential for survival, splenic dysfunction can lead to severe complications, including organ failure, infection, and death. This case study examines a rare presentation of drug-induced splenic septic thrombophlebitis secondary to pancreatitis caused by an adverse reaction to ceftriaxone. While pancreatitis is a known, common cause of splenic infarction and sepsis, there have only been two reported cases of ceftriaxone-induced pancreatitis in the past decade. This case follows a 26-year-old female with a history of congenital truncus arteriosus, who initially presented with Streptococcus mitis bacteremia secondary to prosthetic heart-valve endocarditis and was treated with ceftriaxone. On day 21 of ceftriaxone treatment, the patient returned with septic splenic thrombophlebitis secondary to acute pancreatitis. The patient clinically improved and showed a decrease in inflammatory markers following the discontinuation of ceftriaxone. These findings aim to present a rare case of ceftriaxone-induced pancreatitis. The successful diagnosis and conservative management of our patient underscore the critical importance of interdisciplinary collaboration in the management of complex cases, ultimately avoiding unnecessary surgical interventions.

Clinical features, treatment, and prognosis of SGLT2 inhibitors induced acute pancreatitis

BACKGROUND

Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) have recently been linked to be associated with acute pancreatitis (AP), but the clinical characteristics are unclear. This study investigated the clinical characteristics of SGLT-2i and AP and provided reference for the prevention and treatment of AP.

RESEARCH DESIGN AND METHODS

Case reports, case series, and clinical studies of SGLT2i induced AP were collected by retrieving Chinese and English data from the database until 31 December 2023.

RESULTS

Twenty-one patients were included, with a median age of 50.5 years (range 26,73). SGLT-2i were mainly involved in empagliflozin (13 cases, 61.9%), canagliflozin (4 cases, 19%) and dapagliflozin (4 cases, 19%). The median time from initial administration to the onset of AP was 21 days (range 1, 120). Abdominal pain (21 cases, 100%) was the most commonly complained symptom. The median lipase value was 388 U/L (range 36, 10000), and the median amylase value was 535 U/L (range 26, 3765). Twenty-one patients recovered completely after stopping the drug and receiving conservative treatment.

CONCLUSIONS

SGLT-2i are associated with AP. Given the rising prescription of SGLT-2i, physicians should consider these agents as a potential cause of pancreatitis after excluding other etiologies.

Role of ulinastatin in steroid-induced pancreatitis

Steroid-induced acute pancreatitis is a rare form of pancreatitis that requires intensive care and has a high morbidity and mortality rate as there is no specific treatment. Management of steroid-induced pancreatitis is generally non-specific and supportive. Here, we are presenting a man in his 40s presented with epigastric pain, fever and vomiting. The patient was diagnosed case of rheumatoid arthritis, for which he was receiving regular 5 mg oral prednisolone therapy. Based on history, and clinical, biochemical and radiological imaging a diagnosis of steroid-induced pancreatitis was made, which was successfully managed with the help of ulinastatin and other supportive treatments. A serine protease inhibitor like ulinastatin may be used early in the clinical management of steroid-induced pancreatitis.

Clozapine-associated pericarditis and pancreatitis in children and adolescents: A systematic literature review and pharmacovigilance study using the VigiBase database

BACKGROUND

The literature has paid very little attention to pericarditis, pericardial effusion and pancreatitis during clozapine treatment in children and adolescents.

METHODS

Cases of clozapine-associated pericarditis and pancreatitis in children were studied using searches in: 1) PubMed (June 16, 2023), and 2) the World Health Organization's pharmacovigilance database (June 1, 2022), VigiBase. VigiBase uses a logarithmic measure of disproportionality called the information component (IC).

RESULTS

The PubMed search yielded 3 clozapine-associated pericarditis cases, 1 pancreatitis case and 1 with both. VigiBase provided a significant clozapine-associated pericarditis IC = 3.6 with an IC025 = 2.9 (only 3 cases were expected while 22 were observed). VigiBase provided a significant clozapine-associated pancreatitis IC = 2.2 with an IC025 = 1.4 (only 3 cases were expected while 16 were observed). In VigiBase clozapine-associated pericarditis and pericardial effusion in youth looked similar and on a continuum with myocarditis, as myocarditis, pericarditis and pancreatitis appeared to occur mainly during clozapine titration. Combining PubMed and VigiBase we identified: 1) 29 cases of at least possible clozapine-associated pericarditis/pericardial effusion (6 probable and 23 possible) including 7 cases with and 22 without myocarditis, and 2) 17 cases of clozapine-associated pancreatitis (1 definite and 16 possible). Two of the pancreatitis cases occurred during overdoses. No fatal outcomes were found in any clozapine-associated pericarditis and pancreatitis cases.

CONCLUSIONS

Despite the lack of attention in the literature to clozapine-associated pericarditis and pancreatitis, results demonstrate that they can happen in youth, particularly during titration. Pericarditis and pancreatitis appear to be forms of clozapine-associated inflammation during dose titration.

Drug-Induced Acute Pancreatitis: A Real-World Pharmacovigilance Study Using the FDA Adverse Event Reporting System Database

Timely identification and discontinuation of culprit-drug is the cornerstone of clinical management of drug-induced acute pancreatitis (AP), but the comprehensive landscape of AP culprit-drugs is still lacking. To provide the current overview of AP culprit-drugs to guide clinical practice, we reviewed the adverse event (AE) reports associated with AP in the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) database from 2004 to 2022, and summarized a potential AP culprit-drug list and its corresponding AE report quantity proportion. The disproportionality analysis was used to detect adverse drug reaction (ADR) signals for each drug in the drug list, and the ADR signal distribution was integrated to show the risk characteristic of drugs according to the ADR signal detection results. In the FAERS database, a total of 62,206 AE reports were AP-related, in which 1,175 drugs were reported as culprit-drug. On the whole, metformin was the drug with the greatest number of AE reports, followed by quetiapine, liraglutide, exenatide, and sitagliptin. Drugs used in diabetes was the drug class with the greatest number of AE reports, followed by immunosuppressants, psycholeptics, drugs for acid-related disorders, and analgesics. In disproportionality analysis, 595 drugs showed potential AP risk, whereas 580 drugs did not show any positive ADR signal. According to the positive-negative distribution of the ADR signal for drug classes, the drug class with the greatest number of positive drugs was antineoplastic agents. In this study, we provided the current comprehensive landscape of AP culprit-drugs from the pharmacovigilance perspective, which can provide reference information for clinical practice.

Imaging of hepato-pancreato-biliary emergencies in patients with cancer

Hepato-pancreato-biliary (HPB) emergencies in patients with cancer encompass an extensive array of various conditions, including primary malignancies that require prompt treatment, associated severe complications, and life-threatening consequences arising from treatment. In patients with cancer, the liver can be affected by chemotherapy-induced hepatotoxicity, veno-occlusive disease, Budd-Chiari syndrome, liver hemorrhage, and other complications arising from cancer therapy with all these complications requiring timely diagnosis and prompt treament. Cholecystitis induced by systemic anticancer therapies can result in severe conquences if not promptly identified and treated. The application of immunotherapy in cancer therapy is associated with cholangitis. Hemobilia, often caused by medical interventions, may require arterial embolization in patients with severe bleeding and hemodynamic instability. Malignant biliary obstruction in patients with biliary cancers may necessitate palliative strategies such as biliary stenting. In pancreatic cancer, patients often miss surgical treatment due to advanced disease stages or distant metastases, leading to potential emergencies at different treatment phases. This comprehensive review underscores the complexities of diagnostic and treatment roles of medical imaging in managing HPB emergencies in patients with cancer. It illustrates the crucial role of imaging techniques, including magnetic resonance imaging, computed tomography and ultrasound, in diagnosing and managing these conditions for timely intervention. It provides essential insights into the critical nature of early diagnosis and intervention in cancer-related HPB emergencies, ultimately impacting patient outcomes and survival rates.

Prolonged course of eravacycline leading to acute pancreatitis

Eravacycline is the newest member of the broad-spectrum class of tetracycline antimicrobials. Pancreatitis has been previously associated with the tetracycline class of antibiotics, but, to our knowledge, we believe that this is the first reported case of eravacycline-induced pancreatitis. We describe a 46-year-old male who received eravacycline for treatment of a perirectal abscess. While the patient had slightly elevated lipase levels at baseline post-cardiopulmonary arrest, he developed abdominal pain and a further increase in lipase levels following 10 days of eravacycline, consistent with pancreatitis. Based on the Naranjo adverse drug reaction probability scale, eravacycline was the probable etiology of acute pancreatitis given improvement immediately after discontinuation. Clinicians should be aware of this potential adverse effect of eravacycline and should not initiate eravacycline in those with risk factors for acute pancreatic injury. However, acute pancreatitis should be suspected in all patients complaining of symptoms followed by immediate discontinuation of eravacycline.

Predictors of Pancreatitis Among Patients with Inflammatory Bowel Disease Treated with Vedolizumab: Observation from a Large Global Safety Database

BACKGROUND

Patients with inflammatory bowel diseases (IBDs) are at increased risk of pancreatitis. Data from a global safety database (GSD) were queried to identify risk factors for pancreatitis in vedolizumab-treated patients with IBD.

METHODS

Takeda's GSD was retrospectively queried for case reports (CRs) of adverse events (AEs) following vedolizumab treatment, from licensure (May 20, 2014) through March 31, 2021. Unsolicited and solicited CRs of pancreatitis were coded using the Medical Dictionary for Regulatory Activities (MedDRA) High-Level Term "Acute and chronic pancreatitis." To examine factors associated with severe pancreatitis, serious CRs (serious AEs [SAEs]) were compared with SAEs from a comparator group of 600 random non-pancreatitis AEs. Comparisons were performed using t, χ2, and Fisher's exact tests. Logistic regression was performed to adjust for covariates allowing backward selection.

RESULTS

In total, 196 patients reported pancreatitis in > 700,000 patient-years of vedolizumab exposure. Pancreatitis was serious in 195 patients (99.5%), and non-pancreatitis AEs were serious in 195 of 600 (32.5%) in the random comparator group. In the pancreatitis group, 17 patients (8.7%) had a known history of pancreatitis versus none in the random comparator group. Younger age, vedolizumab indication of ulcerative colitis, concomitant medications (with a risk for pancreatitis), pancreatitis history, and comorbid conditions (especially ongoing pancreatitis) were associated with development of severe pancreatitis.

CONCLUSIONS

These analyses identified factors associated with pancreatitis SAEs in patients with IBD treated with vedolizumab, but do not suggest an increased risk of pancreatitis with vedolizumab. These findings will help inform which patients treated for IBD might have an elevated risk, regardless of treatment.

Rates and predictors of 30-day hospital readmissions in adults for drug-induced acute pancreatitis: A retrospective study from the United States National Readmission Database

BACKGROUND AND AIM

Drug-induced acute pancreatitis (DIAP) linked to several medications is a diagnosis of exclusion and is associated with significant morbidity and mortality, contributing to the US healthcare cost burden. Existing studies on DIAP focus on the drug classes that can cause acute pancreatitis. Hence, our retrospective study aims to determine the rates and predictors for 30-day readmissions (30-DR) in patients with index hospitalization for DIAP.

METHODS

From the Nationwide Readmissions Database, we followed adults admitted for DIAP who were discharged alive for 30 days. During 30-DR, we evaluated the rates, predictors, and outcomes of DIAP.

RESULTS

Of the 4457 DIAP patients surviving at discharge, 12.5% were readmitted at 30 days. During readmissions, the predictors of 30-DR for DIAP were young age, the Charlson-Deyo Comorbidity Index of 2 and 3, protein-energy malnutrition, and dyslipidemia. During 30-DR, DIAP had a higher mortality rate (2.4% vs. 0.7%; P < 0.020), extended hospital stays (5.6 days vs. 4 days, 0.000), and higher hospital charges ($12 983.6 vs. $8 255.6; P 0.000).

CONCLUSIONS

DIAP has high 30-DR rates and poorer outcomes.

Glucocorticoid Treatment in Acute Respiratory Distress Syndrome: An Overview on Mechanistic Insights and Clinical Benefit

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS), triggered by various pathogenic factors inside and outside the lungs, leads to diffuse lung injury and can result in respiratory failure and death, which are typical clinical critical emergencies. Severe acute pancreatitis (SAP), which has a poor clinical prognosis, is one of the most common diseases that induces ARDS. When SAP causes the body to produce a storm of inflammatory factors and even causes sepsis, clinicians will face a two-way choice between anti-inflammatory and anti-infection objectives while considering the damaged intestinal barrier and respiratory failure, which undoubtedly increases the difficulty of the diagnosis and treatment of SAP-ALI/ARDS. For a long time, many studies have been devoted to applying glucocorticoids (GCs) to control the inflammatory response and prevent and treat sepsis and ALI/ARDS. However, the specific mechanism is not precise, the clinical efficacy is uneven, and the corresponding side effects are endless. This review discusses the mechanism of action, current clinical application status, effectiveness assessment, and side effects of GCs in the treatment of ALI/ARDS (especially the subtype caused by SAP).

The Spectrum of Tigecycline-Induced Pancreatitis in Clinical Characteristics, Diagnosis, and Management

Introduction

Tigecycline-induced acute pancreatitis (AP) has been frequently increasingly reported in solid organ transplant patients. This review aimed to summarize the characteristics, possible mechanisms, and management of tigecycline-induced AP.

Methods

Case reports of tigecycline-induced AP published in Chinese or English were collected until February 2023 for retrospective analysis.

Results

Thirty-four patients from 29 articles were included. Fifteen patients (46.9%) had solid organ transplantation, and 4 patients (12.5%) had malignant tumors. Twenty-five patients (89.3%) received a recommended maintenance dose of tigecycline (50 mg q12 h). The median age was 50 years (range 9-87). Compared to the nontransplant patients, the median age of the transplant patients was significantly younger, 44 years (range 12.5-61) versus 57.5 years (range 9-87) (P=0.03). The median time of symptom onset was 7 days (range 2-29), and 91.2% (31/34) were less than 14 days. Typical initial symptoms included abdominal pain (90.6%), nausea (46.9%), vomiting (43.8%), and abdominal distention (21.9%). Most cases were accompanied by elevated levels of pancreatic enzymes. The main radiological features included edematous infiltrate and acute pancreatitis on computed tomography (CT) scan and abdominal ultrasound. Except for one patient who continued tigecycline treatment, all patients discontinued treatment and received symptomatic support such as fasting, acid suppression, and enzyme suppression. The median time to recover pancreatic enzymes to the normal range was 5 days (range 1-43), and the median time to relieve symptoms was 4 days (range 1-12). Four patients died, of whom two died of severe pancreatitis complications and two of cardiogenic shock and septicemia.

Conclusion

Tigecycline-induced AP was a rare and serious complication that occurred mainly within two weeks of the medication. This serious side effect should be kept in mind while treating severe infections especially in transplant recipients.

Black-Box Warnings of Antiseizure Medications: What is Inside the Box?

Antiseizure medications can cause serious adverse reactions and have deleterious drug interactions that often complicate the clinical management of patients. When the US Food and Drug Administration (FDA) wants to alert healthcare providers and patients about the risk of potentially serious or fatal drug reactions, the FDA requires the manufacturers of these medications to format these warnings within a "black-box" border, and prominently display this box on the first section of the package insert; such warnings are called "black-box warnings (BBWs)". The BBW is a way for the FDA to urge physicians to evaluate patients more rigorously and carefully weigh the risks and benefits, before prescribing medication that has the potential to cause serious adverse reactions, and to formulate a plan for close monitoring during therapy. The FDA BBW provides the extra layer of safety but many healthcare providers fail to comply with these warnings. Currently, there are 26 FDA-approved antiseizure medications in the US market, 38% of which have received BBWs, and most of the antiseizure medications with BBWs are older-generation drugs. Some antiseizure medications have multiple BBWs; for example, valproic acid has three BBWs including hepatotoxicity, fetal risk, and pancreatitis, carbamazepine has BBWs of serious skin and hematological reactions, and felbamate also has two BBWs including hepatic failure and aplastic anemia. The purpose of this review is to provide insight into each BBW received by antiseizure medications and discuss the FDA recommendations for evaluating the drug benefit/risk, and for monitoring parameters before the initiation of and during treatment.

Drug-Induced Acute Pancreatitis in Hospitalized COVID-19 Patients

Coronavirus disease-19 (COVID-19), caused by SARS-CoV-2, is a systemic disease that affects not only the respiratory system, but also other systems, including gastrointestinal. A great number of different drugs have been used on hospitalized patients for the management of COVID-19, and acute pancreatitis (AP) has been reported as a complication or side effect of these drugs. The development of drug-induced acute pancreatitis (DIAP) follows a complex of pathophysiological mechanisms, and particular risk factors play a key role. Diagnosis of DIAP depends on specific criteria, and based on these, a drug may be characterized as having a definite, probable or possible connection with AP. The aim of this review is to present the medications that are used for COVID-19 management and are associated with AP in hospitalized patients. The list of these drugs mainly includes corticosteroids, glucocorticoids, non-steroidal anti-inflammatory drugs (NSAIDs), antiviral agents, antibiotics, monoclonal antibodies, estrogens and anesthetic agents. Moreover, the prevention of the development of DIAP is vital, especially for critically ill patients who may receive multiple drugs. DIAP management is mainly non-invasive and the first step concerns the exception of the suspicious drug from patients therapy.

Doxycycline Induced Pancreatitis: An Uncommon Complication of a Common Drug

We describe the risk factors for the development, timing, and severity of doxycycline induced acute pancreatitis (DIAP) in two case reports and a review of prior published cases, to better understand DIAP. Clinicians must maintain a high level of suspicion for DIAP in patients presenting with acute pancreatitis, while on doxycycline therapy. The latency and severity of DIAP are variable, making diagnosis challenging. Treatment includes bowel rest, hydration, and discontinuation of doxycycline.

Acute Pancreatitis: Diagnosis and Treatment

Acute pancreatitis is a common indication for hospital admission, increasing in incidence, including in children, pregnancy and the elderly. Moderately severe acute pancreatitis with fluid and/or necrotic collections causes substantial morbidity, and severe disease with persistent organ failure causes significant mortality. The diagnosis requires two of upper abdominal pain, amylase/lipase ≥ 3 ×upper limit of normal, and/or cross-sectional imaging findings. Gallstones and ethanol predominate while hypertriglyceridaemia and drugs are notable among many causes. Serum triglycerides, full blood count, renal and liver function tests, glucose, calcium, transabdominal ultrasound, and chest imaging are indicated, with abdominal cross-sectional imaging if there is diagnostic uncertainty. Subsequent imaging is undertaken to detect complications, for example, if C-reactive protein exceeds 150 mg/L, or rarer aetiologies. Pancreatic intracellular calcium overload, mitochondrial impairment, and inflammatory responses are critical in pathogenesis, targeted in current treatment trials, which are crucially important as there is no internationally licenced drug to treat acute pancreatitis and prevent complications. Initial priorities are intravenous fluid resuscitation, analgesia, and enteral nutrition, and when necessary, critical care and organ support, parenteral nutrition, antibiotics, pancreatic exocrine and endocrine replacement therapy; all may have adverse effects. Patients with local complications should be referred to specialist tertiary centres to guide further management, which may include drainage and/or necrosectomy. The impact of acute pancreatitis can be devastating, so prevention or reduction of the risk of recurrence and progression to chronic pancreatitis with an increased risk of pancreas cancer requires proactive management that should be long term for some patients.

Stocky/Packed Pancreas: A Case of Focal Drug-Induced Acute Pancreatitis Mimicking Cancer

Drug-induced acute pancreatitis (DIP) is a recognised but underreported entity in the literature. Immunotherapy drugs have been described as one possible emerging cause, although the pathogenic mechanism is still largely unclear. To date, only a few cases have been reported, even if in recent times there is an over-increasing awareness of this pathologic entity. The imaging-based diagnosis of DIP can be difficult to establish, representing a real challenge for a radiologist, especially when the inflammatory disease appears as a focal mass suspicious for a malignancy. Case report: We herein report the case of a 71-year-old man with a known history of partially responsive lung adenocarcinoma subtype with high programmed cell death ligand 1 (PD-L1) expression, who underwent positron emission tomography (PET)/computed tomography (CT) imaging follow-up after one year of immunotherapy. The exam revealed a stocky/packed lesion in the pancreatic body, with increased 18F-fluorodeoxyglucose (FDG) accumulation highly suggestive of pancreatic cancer, which finally was proven to be a DIP induced by immunotherapy. Conclusion: Distinguishing between focal DIP and pancreatic neoplasm is, therefore, crucial for timely therapeutic management and prognostic stratification. A deep knowledge of possible imaging pitfalls coupled with a comprehensive clinical and laboratory assessment is pivotal to avoid any delays in diagnosis.

The Effect of Chemotherapy Induction Therapy on the Pancreas in Patients with Acute Lymphoblastic Leukemia

Background

The effect of chemotherapy induction on the pancreatic in patients with acute lymphoblastic leukemia is not described in Ethiopia. The study determined the chemotherapy drug-induced pancreatitis in patients with acute lymphoblastic leukemia.

Method

A preexperimental study (pretest and posttests) was conducted in forty patients with acute lymphoblastic leukemia. For some skewed data, a log transformation was computed. The back transformation was then calculated. Descriptive statistics and a mixed-model ANOVA were used to analyze the data. A post hoc Bonferroni test was used. A p value < 0.05 was declared statistically significant.

Results

In this study, no clinically significant acute pancreatitis occurred. Elevated amylase and lipase levels, indicating grade 2 acute pancreatitis, were observed in 25% and 17.5% of patients, respectively. Amylase enzyme levels in children differed significantly from preinduction to the second week of induction (p = 0.001) and fourth week of induction (p = 0.001), as well as between the second and fourth weeks of induction (p = 0.033), but adults' amylase enzyme levels did not differ significantly (p = 0.2). Lipase levels in adults are nearly identical in all three measures, implying that there is no statistically significant difference (p = 0.775). However, the level of lipase enzyme in children was significantly higher from baseline to two and four weeks of induction (p = 0.007) but not between two and four weeks of induction (p = 0.129).

Conclusion

Clinically significant acute pancreatitis did not occur, but patients experienced mild (grade 2) acute pancreatitis. Amylase and lipase enzymes responded significantly to chemotherapy induction in children. Chemotherapy drugs should be given without altering pancreatic enzymes, specifically in children.

Pancreas and Adverse Drug Reactions: A Literature Review

Adverse drug reactions (ADRs) affecting the pancreas are a heterogeneous group of side effects that cause damage to pancreatic cells. Various mechanisms such as hypersensitization, sphincter of Oddi constriction, direct cytotoxic and metabolic effects on pancreatic cells, and dose-dependent idiosyncrasy lead to intrapancreatic activation of pancreatic enzymes resulting in drug-induced acute pancreatitis. Several medications have been linked with the development of pancreatic cancer. Pancreatic cancer may result from proinflammatory, proliferative, and antiapoptotic effects. Diabetogenic effect of drugs, which is understood as impairment of insulin secretion, may occur due to direct destruction of β cells, systemic toxicity affecting pancreatic islets and cell membrane glucose transporters, induction of Th1-type autoimmune response, and impairment of voltage-gated calcium channels in β cells, endoplasmic reticulum stress, and insulin signaling. A better understanding of ADRs that affect the pancreas may contribute to improving the awareness of clinicians and patients and reducing potential harmful side effects of implemented therapies.

Investigation of the potential association between the use of fluoxetine and occurrence of acute pancreatitis: a Danish register-based cohort study

Background

There is currently conflicting evidence of the association between the use of selective serotonin reuptake inhibitors (SSRIs) and acute pancreatitis. The SSRI fluoxetine has been suspected to be the driver of this serious outcome. Therefore, this study aims to investigate the potential association between fluoxetine use and the occurrence of acute pancreatitis.

Methods

We conducted a nationwide cohort study using Danish register-based data from 1996 to 2016. The exposed group were new users of fluoxetine (1-year washout). The control subjects were new users of citalopram or SSRIs, excluding fluoxetine. The outcome was an incident diagnosis of acute pancreatitis with a 5-year washout. We used an intention-to-treat approach following patients for a maximum of 6 months. Cox regression analyses were performed, estimating hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for age/sex, comorbidities and co-medications, using propensity score adjustment and matching.

Results

In the propensity score-matched analyses, 61 783 fluoxetine users were included. The incidence rates among users of fluoxetine and other SSRIs were 5.33 (3.05–8.66) and 5.36 (3.06–8.70) per 10 000 person-years, respectively. No increased risk of acute pancreatitis was identified following fluoxetine exposure compared with either citalopram [HR 1.00, 95% CI 0.50–2.00) or other SSRIs (0.76, 0.40–1.46).

Conclusions

Fluoxetine use was not associated with an increased risk of acute pancreatitis compared with citalopram or other SSRIs. The absolute risk of acute pancreatitis was low and did not vary between different SSRIs. Further research is needed to determine whether there is a class effect on the risk of acute pancreatitis.

Acute pancreatitis caused by tigecycline: A case report and literature review

RATIONALE

There is evidence that tigecycline has broad-spectrum antibiotic activity against a variety of complicated infections. However, adverse effects are inevitable, including gastrointestinal side effects such as nausea, vomiting, and diarrhea; in 2006, acute pancreatitis was also brought into the side-effect list after postmarketing surveillance. Here, we present a case of tigecycline-induced acute pancreatitis.

PATIENT CONCERNS

An 87-year-old female patient with urinary tract infection received an intravenous drip of tigecycline for 6 days, after which she developed abdominal distension, vomiting, abdominal pain, and abdominal rigidity.

DIAGNOSIS

The patient was suspected to have tigecycline-induced acute pancreatitis.

INTERVENTIONS

Tigecycline was discontinued immediately, and the patient received a series of immediate treatments including an indwelling gastric tube for continuous gastrointestinal decompression and inhibition of gastric acid and pancreatic enzyme secretion.

OUTCOMES

Following initial interventions, we observed that the patient's symptoms improved significantly, and abdominal distension, vomiting, abdominal pain, and abdominal rigidity were slightly relieved. After 5 days of follow-up, blood lipase and amylase levels decreased to normal levels. Unfortunately, the patient developed convulsions during the use of multiple antibiotics after 1 week and then died of septic shock and acute liver failure.

LESSONS

Acute pancreatitis caused by tigecycline is rare. However, in the application of antibiotics, the possibility of adverse effects must be considered, and antibiotics should be used reasonably. If the patient has relevant symptoms, it is necessary to stop using tigecycline immediately, carry out symptomatic treatment, and change to other types of antibiotics for antibacterial treatment.

Another Case of Lisinopril-Induced Acute Pancreatitis

Lisinopril as a cause for acute drug-induced pancreatitis is an emerging phenomenon that due to its generally low-risk profile often goes unnoticed. The true incidence of drug-induced pancreatitis is unknown, probably because of its nonrecognition among differential diagnosis. Only a handful of lisinopril-induced pancreatitis has been discussed in the literature, and little epidemiological evidence exists to establish true causality. Additionally, many of these reports have been met with skepticism claiming that it is difficult to isolate a true cause since many of these patients had comorbidities or were concomitantly taking other medications that may have contributed to the pancreatitis. Here, we report a case in which a generally otherwise healthy patient presented with acute drug-induced pancreatitis caused by an angiotensin-converting enzyme (ACE) inhibitor taken eight weeks prior to the onset of symptoms. The drug was immediately stopped, and the patient recovered well, with no complications.

A Case of Acute Pancreatitis in a Patient Receiving High-Dose Steroids for Optic Neuritis

Although rare, drug-induced pancreatitis is an important cause of acute pancreatitis. The diagnosis of drug-induced pancreatitis remains a challenge for clinicians. Steroids are one of the frequently used drugs in hospitals for many acute illnesses. Patients presenting with signs and symptoms of acute pancreatitis, with a recent history of steroid use, in the absence of other potential causes, should be approached with a high suspicion for steroid-induced pancreatitis to ensure a timely diagnosis. We describe a case of a 57-year-old female treated for optic neuritis of the left eye with high doses of Methylprednisolone for five days, who presented to the emergency room with acute abdominal pain within 24 hours of discharge. A detailed evaluation of the patient's medical history and exclusion of other probable etiologies confirmed the diagnosis of steroid-induced pancreatitis. Withdrawal of the offending agent and supportive care resolved the underlying acute pancreatitis.

Assessment of serum amylase, lipase and associated factors among patients with visceral leishmaniasis treated with sodium stibogluconate/paromomycin at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia

BACKGROUND

Visceral leishmaniasis (VL) is a life-threatening parasitic disease next to malaria, which is responsible for the death of 50,000 patients annually. It has three major clinical stages, including visceral, cutaneous, and mucocutaneous leishmaniasis. Ethiopia is one of the east African countries commonly affected with leishmanisis disease. There are many drugs for leishmaniasis, including sodium stibogluconate and paromomycin combined therapy. However, the adverse effect of those combined drugs is not well-defined. Therefore, the purpose of this study was to assess serum amylase, lipase, and associated factors among patients with VL treatment with those combined drugs.

METHODS

Hospital-based cross-sectional study was conducted at the University of Gondar Comprehensive Specialized Hospital Leishmaniasis Research and Treatment Center from February to September 2020 G.C. Simple random sampling technique was utilized to select study participants. The study participants who fulfill the inclusion criteria were included in the study with written informed consent. 5 ml of blood was withdrawn by an experienced health professional to analyze serum amylase and lipase level. Descriptive data was presented by tables, charts and graphs. Data was cleared, entered by Epi-data version 3.1 then transfer to STATA 14.1 SE version and for analysis paired t-test was used, for factors correlation and regression was used. Those factor variable who have p-value <0.25 was filtered and goes to multivariate regression and p-value <0.05 was considered as significant variables.

RESULTS

The result of this study showed that there was a significant mean difference between serum pancreatic amylase and lipase before and after treatment. The mean ± SD level of serum amylase after treatment showed a statistically significant elevation (P<0.001) as compared to its level before treatment. Similarly, the mean ± SD level of serum lipase after treatment showed a statistically significant elevation (P<0.001) as compared to its level before treatment. There was also significant association between age and baseline serum amylase as compared to serum amylase after treatment. Similarly, there was also significant relation of age and serum lipase with serum lipase after treatment.

CONCLUSION

In this study, the level of serum amylase and lipase at treatment of cure was higher and there was an increase in mean serum amylase and lipase after a patient taking sodium stibogluconate and paromomycin combined drugs. Consequently, the elevated result of these biochemical profiles mainly associated with drug induced adverse effect and associated risk factors in VL patients.

Assessment of pancreatitis associated with tocilizumab use using the United States Food and Drug Administration Adverse Event Reporting System database

Tocilizumab (TCZ) is used to treat rheumatoid arthritis and other systemic inflammatory disorders. There is some evidence suggesting the occurrence of pancreatitis following TCZ use. We aimed to determine the reporting of pancreatitis following TCZ use in comparison with other drugs using the United States Food and Drug Administration Adverse Event Reporting System (FAERS) database. We extracted adverse event reports submitted to FAERS during 2013-2019. A reporting odds ratio (ROR) with the lower bound 95% confidence interval (CI) > 1 and a lower limit of a two-sided 95% interval of information component (IC025) more than zero was considered significant. Following deduplication, 3,383,910 adverse event reports were available; 144 (0.004%) reports were of pancreatic adverse events associated with TCZ use, and 15,907 (0.47%) associated with other drugs. Of the 144 cases, 74 (51.39%) received concomitant medications with pancreatotoxic potential. The likelihood of reporting of pancreatic events, compared with any other adverse event, with TCZ use was 1.32 times higher than that with other drugs. The lower bound of the 95% CI of the ROR and IC remained above the criteria of significance throughout the study period, except 2013. The findings suggest disproportionately high reporting of pancreatitis in patients receiving TCZ as compared with other drugs. This marginally high reporting is not likely to be of immediate clinical concern and needs to be interpreted cautiously.

Rapidly Growing Mycobacterium tuberculosis in the Form of Empyema Necessitans: A Case Report

We present a case of rapidly growing disseminated Mycobacterium tuberculosis (MTB) that presented as an empyema necessitans (EN) in a 65-year-old woman with a single right lung transplant admitted for progressive dyspnea. While hospitalized, she had daily fevers and was found to have a right-sided chest wall abscess and pleural effusion. Acid-fast bacilli cultures from the abscess and pleural fluid grew MTB within 4 and 6 days, respectively. Blood cultures later grew MTB as well. Upon initiation of rifampin, isoniazid, pyrazinamide, and ethambutol, she developed hemorrhagic pancreatitis and distributive shock secondary to antituberculosis medications and disseminated MTB. Noteworthy features of this case include the rapid rate of MTB culture growth in less than a week, the development of a likely donor-derived MTB EN, and the clinical challenges of MTB screening and MTB infection management in a solid organ transplant recipient.

Temporary Trend, Characteristics and Clinical Outcomes of Acute Pancreatitis Patients Infected with Human Immunodeficiency Virus

BACKGROUND

Compared to general population, human immunodeficiency virus (HIV) infection may increase frequency of acute pancreatitis (AP); however, evidence regarding effects of HIV infection on AP-related outcomes is limited and controversial.

AIMS

We aim to investigate the temporary trend, characteristics and clinical outcomes of AP infected with HIV.

METHODS

We reviewed data from the 2003-2014 National Inpatient Sample to identify patients with a primary diagnosis of AP. The primary outcomes (in-hospital mortality, acute respiratory failure, acute kidney injury, and prolonged length of stay [LOS]) and secondary outcomes (gastrointestinal hemorrhage, sepsis and total cost) were compared between patients with and without HIV infection using univariate, multivariable and propensity score matching analyses.

RESULTS

Of 594,106 patients diagnosed with AP, 6775 (1.14%) had HIV infection. Patients with HIV were more likely to be younger, black, male, less likely to be gallstone-related and had lower rate of interventions. Multivariable analyses based on multiple imputation revealed that HIV infection was associated with higher risk of mortality (odds ratio [OR]: 1.74; 95% confidence interval [CI] 1.34-2.25), acute kidney injury (OR: 1.13; 95% CI 1.19-1.44), prolonged LOS (OR: 1.26; 95% CI 1.15-1.37) and 6% higher cost. There were no differences in sepsis, gastrointestinal bleeding, and respiratory failure between groups.

CONCLUSIONS

HIV infection is associated with adverse outcomes including increased mortality, acute kidney injury and more healthcare utilization in AP patients. More assertive management strategies like early intravenous fluid resuscitation in HIV patients hospitalized with AP to prevent acute kidney injury may be helpful to improve clinical outcomes.

A case report of tigecycline induced acute pancreatitis in a renal transplant patient and review of the literature: Should we avoid tigecycline in patients on calcineurin inhibitors?

Tigecycline has been approved by the US (United States) Food and Drug Administration in a variety of complicated infections due to its broad-spectrum antibiotic activity. Following phase III trials, the product label was revised and acute pancreatitis was listed as an adverse effect. Its safety profile in special groups such as renal transplant patients is not exactly known. We report the first case of unintentional rechallenge of tigecycline induced pancreatitis in a renal transplant patient. Ten days following the renal transplantation, a 35-year-old patient presented to the clinic with acute rejection. He received anti-thymocyte globulin (ATG) and pulse steroid treatments for rejection. Following the treatment, he developed perianal cellulitis and tigecycline was started. Nine days following initiation of tigecycline he received thrombectomy for his incidental cardiac thrombus. One day after thrombectomy, he developed acute pancreatitis (AP). Thrombectomy was suspected to be the cause of AP. During hospitalization for transplant rejection, tigecycline was re-started for a newly developed complicated abdominal infection. On the third day of the tigecycline re-treatment, he developed a second episode of AP. Following tigecycline withdrawal, his symptoms resolved and serum pancreatic enzymes returned to normal, thus AP was ultimately attributed to tigecycline. This lethal side effect should be kept in mind while treating severe infections in renal transplant recipients.

Doxycycline Induced Severe Acute Pancreatitis: A Rare Finding To A Common Medication

Doxycycline is a commonly prescribed antibiotic with growing evidence suggesting a possible linkage with drug-induced acute pancreatitis. We present an elderly female presenting with severe acute pancreatitis likely secondary to doxycycline therapy after thorough investigation. We reviewed the evidence linking doxycycline-inducing acute pancreatitis and signs and symptoms for severe disease. Early recognition and intervention are critical for positive patient outcomes.

A Drug-Induced Acute Pancreatitis Retrospective Study

BACKGROUND AND AIMS

Drugs are considered a relatively rare and understudied cause of acute pancreatitis (AP). The lack of convincing and conclusive data on drug-induced AP (DIAP) complicates the diagnosis as well as the identification of the causative drug. The aim of this study is to document causes of DIAP cases that occurred in the Saguenay-Lac-Saint-Jean (SLSJ) population.

METHODS

We have conducted a retrospective and descriptive population-based study of DIAP cases that occurred between 2006 and 2014 in the six hospitals serving the entire SLSJ population. Cases were selected from the Quebec Ministry of Health hospitalizations registry (MED-ECHO) administrative public database. A medical chart review was performed in an attempt to characterize DIAP hospitalizations and to identify the imputable drugs.

RESULTS

During the studied period, 75 cases (30.7% male, 69.3% female) were included totaling 90 hospitalizations for DIAP. Among them, 50 causative drugs were identified and were distributed in 17 different drug classes. Recurrent DIAPs were documented in 13 cases, and among them, 6 cases have experimented a positive rechallenge. Six drugs (5-fluorouracil, atorvastatin, bortezomib, nilotinib, rosuvastatin, and triamcinolone) were associated with the highest degree of evidence. The most common causative drugs of DIAP hospitalization were azathioprine (n = 7), followed by atorvastatin (n = 6), hydrochlorothiazide (n = 5), rosuvastatin (n = 4), and codeine (n = 4).

CONCLUSIONS

This study has added new evidences about potentially pancreatitis-associated drugs in literature. This is the first study to report definite 5-fluorouracil- and triamcinolone-induced AP. An updated version of the evidence-based literature review is needed to support the clinicians in the identification of the causative drugs.

A rare cause of pediatric acute pancreatitis: Perindopril intoxication

Acute pancreatitis is a reversible inflammatory condition of the pancreas. It usually develops on the basis of trauma, structural abnormalities, and chronic systemic diseases. A definitive causal correlation between a drug and acute pancreatitis is quite difficult for clinicians. Drugs play a vital role in the etiology in approximately 10% of children with pancreatitis. More than 50 drugs including angiotensin-converting enzyme inhibitors have been reported to cause pancreatic damage. There was no pediatric case report developed pancreatitis following perindopril use. A pediatric case of pancreatitis following perindopril intake was presented in this article to emphasize pancreatitis, which is one of the complications that may occur after drug intake.

Acute pancreatitis induced by combination chemotherapy used for the treatment of acute myeloid leukemia: A case report

RATIONALE

Drug-induced pancreatitis (DIP) is a kind of acute pancreatitis with a relatively low incidence. There are many cases of acute pancreatitis (AP) caused by chemotherapeutic agents that have been reported. However, few reports focus on the combination of chemotherapeutic agents that induce acute pancreatitis. This article aims to retrospectively analyze a case of DIP and to explore the relationship between chemotherapeutic agents and acute pancreatitis.

PATIENT CONCERNS

Here, we report a 35-year-old Chinese female patient who was diagnosed as acute myeloid leukemia with BCR/ABL expression. After induction chemotherapy of daunorubicin and cytarabine, bone marrow aspiration showed: Acute myeloid leukemia-not relieved (AML-NR). Then the regimen of homoharringtonine, cytarabine and dasatinib was started. The patient developed abdominal pain on the 14th day of chemotherapy. Laboratory tests showed elevated serum amylase (AMY) and lipase (LIPA). Computed tomography (CT) of the abdomen revealed a swollen pancreas with blurred edges and thickened left prerenal fascia.

DIAGNOSIS

The patient was diagnosed as DIP by the symptoms of upper abdominal pain and the change of CT images. Other common causes of AP were excluded meanwhile.

INTERVENTIONS

The chemotherapy was stopped immediately. And after fasting, fluid infusion and inhibiting the secretion of the pancreas, the symptoms were relieved.

OUTCOMES

DIP relapsed when the regimen of aclacinomycin + cytarabine + G-CSF + dasatinib regimen (G-CSF (400ug/day, day 1 to 15), cytarabine (30 mg/day, day 2 to 15), aclacinomycin (20 mg/day, day 2 to 5)and dasatinib (140 mg/day, continuously)) was given, and was recovered after treatment for AP was performed.

LESSONS

To choose the best treatment plan for patients, clinicians should raise awareness of DIP, and should know that chemotherapeutic agents can induce pancreatitis and the combination of chemotherapeutic agents may increase the risk of drug-induced pancreatitis.

Steroid-Induced Pancreatitis: Establishing an Accurate Association Poses a Challenge

The association between steroids and pancreatitis has been reported in the literature. However, due to its rarity, it can be challenging to make an early diagnosis. Hence, when diagnosing patients presenting with signs and symptoms of pancreatitis, there should be a high suspicion for medication-induced variants, after ruling out other common causes. In our report, we present the case of an individual with recurrent pancreatitis caused by the use of prednisone for musculoskeletal pain, the probable cause being steroids due to a high Naranjo score. The patient experienced clinical improvement with the resolution of pancreatitis after the steroids were discontinued.

Analysis of clinical characteristics of tigecycline-induced acute pancreatitis

WHAT IS KNOWN AND OBJECTIVE

The purpose of this study is to explore the clinical characteristics of tigecycline-induced acute pancreatitis.

METHODS

We searched the PubMed/Medline, Web of Knowledge, OVID, Elsevier, Springer Link, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and Chinese VIP databases from 2005 and identified 19 studies of tigecycline-induced acute pancreatitis involving a total of 22 patients for inclusion in a retrospective analysis.

RESULTS AND DISCUSSION

The median (range) age of 22 patients with acute pancreatitis was 58 years (range 9-83). Overall, the median (range) time of symptom onset was 6.5 days (range 2-28), or 6 days (range 2-14) and 6 days (range 3-28) in patients with or without a loading dose of tigecycline, respectively. Symptoms included nausea, vomiting and abdominal distension (73%) and abdominal pain (73%); 90% (18/20) of patients developed mild acute pancreatitis (MAP), and 10% (2/20) developed severe acute pancreatitis (SAP). Computed tomography (CT) scans showed oedematous infiltrate in 56% (10/18) of cases and acute pancreatitis in 28% (5/18) of cases. The median (range) level of lipase and amylase was 936U/L (range 382-4089) and 588U/L (range 312-1166), respectively. The median (range) time to recovery of symptoms was 4 days (range 1-10), and the time for recovery of pancreatic enzymes to the normal range was 5 days (range 1-30) after the withdrawal of tigecycline in all patients.

WHAT IS NEW AND CONCLUSION

Clinicians should be particularly mindful of clinical signs and symptoms, the level of serum pancreatic enzymes and abdominal CT images in order to monitor the development of pancreatitis when using tigecycline.

Cocaine-Induced Acute Pancreatitis: A Rare Etiology

An 18-year-old male with a medical history of trigeminal neuralgia presented to the emergency department with complaints of severe abdominal pain associated with nausea, projectile vomiting, and watery diarrhea with no fever, rigors, and chills. The abdominal examination was unremarkable. His lab results showed elevated serum lipase and amylase. Gallstones were ruled out by abdominal ultrasonography. His computed tomography (CT) revealed pancreatic enlargement with ill-defined borders. He reported cocaine use but had no history of alcohol abuse. A urine drug screen was positive for cocaine. He was managed conservatively with a possible diagnosis of acute pancreatitis due to cocaine abuse after carefully ruling out other causes. The patient was symptom-free on day 7 and discharged from hospital on day 8 with follow-up with his gastroenterology doctor and drug counseling service. Although cocaine-induced pancreatitis is rare, it should be considered a differential diagnosis in patients with a history of cocaine use.

Successful clozapine rechallenge following recurrent clozapine-associated pancreatitis: a case report

Background

Acute pancreatitis is a rare but recognised complication of clozapine leading to termination of treatment.

Case presentation

We present the case of a 39-year-old man with treatment-resistant schizoaffective disorder and a history of recurrent acute pancreatitis attributed to clozapine. After 15 years of unremitting symptoms with disruptive and aggressive behaviour, he was admitted for a clozapine rechallenge. Despite experiencing two further episodes of acute pancreatitis during clozapine treatment that led to its temporary withdrawal, clozapine was successfully re-established under gastroenterology consultation with close monitoring which resulted in progressively marked improvement of his mental state.

Conclusions

This case demonstrates that patients who develop pancreatitis during clozapine treatment may be cautiously rechallenged with specialist gastroenterology support.

Reporting of acute pancreatitis by radiologists-time for a systematic change with structured reporting template

Acute pancreatitis has a wide array of imaging presentations. Various classifications have been used in the past to standardize the terminology and reduce confusing and redundant terms. We aim to review the historical and current classifications of acute pancreatitis and propose a new reporting template which can improve communication between various medical teams by use of appropriate terminology and structured radiology template. The standardized reporting template not only conveys the most important imaging findings in a simplified yet comprehensive way but also allows structured data collection for future research and teaching purposes.

The Risk of Acute Pancreatitis and Selective Serotonin Reuptake Inhibitors Use: A Meta-Analysis of Case-Control Studies

Background/Objective:

Some case series and case report have shown the association between the risk of acute pancreatitis and use of selective serotonin reuptake inhibitors. The results of systematic studies were not consistent.

Methods:

A meta-analysis was performed to investigate the risk of acute pancreatitis associated with use of selective serotonin reuptake inhibitors.

Results:

There was no statistical association between the risk of acute pancreatitis and selective serotonin reuptake inhibitors use (odds ratio: 1.19, 95% confidence interval: 0.93-1.51).

Conclusions:

Despite reaching no statistical significance, the possibility of the association between the risk of acute pancreatitis and selective serotonin reuptake inhibitors use cannot be totally excluded.

Acute pancreatitis induced by Tadalafil: a case report

Acute pancreatitis is commonly caused by gallstones or alcohol abuse. Also, this complication has rarely been associated with other etiologies like drugs in some reports. We report the case of a 43-year-old man with 10-days history of taking Tadalafil for erectile dysfunction. The patient was presented to the emergency room with manifestations of acute pancreatitis. This diagnosis was confirmed after clinical examination, laboratory tests, and radiologic evaluation. Other probable etiological factors were ruled out. A total score of seven using Naranjo Adverse Drug Reaction Probability Scale clarifies a probable diagnosis of drug-induced acute pancreatitis in this case. The reported case of acute pancreatitis was most likely induced with Tadalafil.
