Drug-induced pancreatitis: an update

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.

Risk factors for drug-related acute pancreatitis: an analysis of the FDA adverse event reporting system (FAERS)

Objective: While several drugs have been linked to acute pancreatitis (AP), the AP-related risk of most drugs remains unclear. This study investigated the risk factors for drug-induced AP by analyzing a large dataset from the FDA Adverse Event Reporting System (FAERS). Methods: The reporting odds ratios (ROR) were used to assess the reports of drug-induced AP from the first quarter of 2004 to the second quarter of 2022. Single-factor, LASSO, and multi-factor regression analysis were performed to explore drug-related AP-related risk factors. Bonferroni correction was applied for the multiple comparisons performed. Results: A total of 264 drugs associated with AP, including antineoplastic drugs (35/264), antidiabetic drugs (28/264), antibacterial drugs (24/264), immunomodulatory drugs (11/264), antipsychotic drugs (6/264), and other drugs (160/264) were retrieved. Multi-factor analysis showed that males, age 41-54 years old, and 36 drugs, including Tigecycline, were risk factors for drug-related AP. The median time to drug-related AP onset was 31 days (interquartile range [IQR] 7-102 days) and about 75% of adverse events occurred within 100 days. Conclusion: These findings may help clinicians to identify drug-related AP at the early stage and can be used to inform future studies of drug-related AP pathogenesis.

Drug-Induced Acute Pancreatitis in Adults: Focus on Antimicrobial and Antiviral Drugs, a Narrative Review

Acute pancreatitis (AP) is an acute inflammation of the pancreas caused by the activation of digestive enzymes in the pancreatic tissue. The main causes of AP are cholelithiasis and alcohol abuse; less commonly, it can be caused by drugs, with a prevalence of up to 5%. Causal associations between drugs and pancreatitis are largely based on case reports or case series with limited evidence. We reviewed the available data on drug-induced AP, focusing on antimicrobial drugs and antivirals, and discussed the current evidence in relation to the classification systems available in the literature. We found 51 suspected associations between antimicrobial and antiviral drugs and AP. The drugs with the most evidence of correlation are didanosine, protease inhibitors, and metronidazole. In addition, other drugs have been described in case reports demonstrating positive rechallenge. However, there are major differences between the various classifications available, where the same drug being assigned to different probability classes. It is likely that the presence in multiple case reports of an association between acute pancreatitis and a drug should serve as a basis for conducting prospective randomized controlled trials to improve the quality of the evidence.

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.

Necrotizing Pancreatitis Secondary to Hydrochlorothiazide and Alogliptin: A Case Report

Drug-induced pancreatitis occurs rarely but should be considered when more common causes have been ruled out. While simple to treat, mortality increases should it progress to a necrotizing process. Here, we present the case of a patient simultaneously using two drugs associated with pancreatitis, which we considered acted synergistically and consequently worsened the patient's outcome.

Pancreatitis in the Complex Care Population: Presentation, Incidence, and Severity

OBJECTIVES

To describe the incidence and presentation of pancreatitis in Children with Medical Complexity (CMC) while evaluating severity of disease and outlining risk factors.

METHODS

This was a retrospective chart review between January 2010 and December 2019 of patients seen in the complex care clinic at Nationwide Children's Hospital (NCH) and Cincinnati Children's Hospital Medical Center (CCHMC). Data collected included sex, underlying diagnosis, family history of pancreatitis, type of pancreatitis, signs/symptoms, abdominal imaging, severity of attack, and presence of various risk factors associated with pancreatitis. Severity and diagnosis of pancreatitis was determined based on North American Society for Pediatric Gastroenterology, Hepatology and Nutrition criteria.

RESULTS

One hundred and twelve patients from both institutions were included, 62% from NCH, median age 11.5 [interquartile range (IQR): 5-16 years], 50% male. Most patients were less than 18 years of age with a median age of 8 years (IQR: 4-13 years). Underlying diagnoses included seizures (67%), cerebral palsy/spastic quadriplegia (65%), diabetes (3.6%), and mitochondrial disease (3%). Majority of patients were found to have multiple underlying diagnoses (88%). Incidence of pancreatitis for both institutions was 336 of 100,000 patients/year which is significantly higher than the general pediatric population ( P < 0.0001). Majority of first episodes of pancreatitis were mild (82%) with abdominal pain as the predominant symptom (50%). Adult patients were more likely to have pancreatitis related to medication use than pediatric patients (70% vs 38%, respectively P = 0.007).

CONCLUSIONS

Individuals in the CMC population at our institutions have a high incidence of pancreatitis with unique risk factors compared to the general pediatric/young adult populations.

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.

Acute Pancreatitis in Childhood: A 10-Year Experience From A Thai University Surgical Center

OBJECTIVES

This study aimed to describe etiology, management, and health outcomes of children developing acute pancreatitis at a tertiary Thailand pediatric surgery center.

METHODS

Medical case records of all index cases during 2006-2016 were analyzed and reported.

RESULTS

There were 42 male and 37 female patients, with a mean (standard deviation) age of 10.4 (4.5) years, included in the study. Medications were the commonest etiology for 39.3% of acute pancreatitis attacks, 11.4% for biliary tract disease cases, and 8% for postinterventional studies. In 30% of cases, no cause(s) was defined. Sixty-two patients (78.5%) had elevated serum lipase on hospital admission, whereas only 30.4% showed a raised amylase. Hospital stay was 15 days (interquartile range, 6-27 days). Two major complications in the series were pseudocysts (8.8%) and necrotizing pancreatitis (7.6%). Etiological factors and/or antibiotics were not directly linked to any specific complications. Seventeen children (22.8%) had 1 recurrent episode of acute pancreatitis documented. Mortality rate in index cases was 28%, with a higher percentage harboring a preexisting illness (34.4% vs 5.6%; P = 0.01) and in male than in female patients (41% vs 14%; P = 0.01).

CONCLUSIONS

Deaths from pediatric acute pancreatitis are more prevalent in male individuals and those with a preexisting illness. Targeted strategies aimed at "highest-risk" patients may potentially offset mortality.

Systematic review-pancreatic involvement in inflammatory bowel disease

BACKGROUND

Inflammatory bowel disease (IBD) is a chronic inflammatory immune-mediated disorder of the gut with frequent extra-intestinal complications. Pancreatic involvement in IBD is not uncommon and comprises a heterogeneous group of conditions, including acute pancreatitis (AP), chronic pancreatitis (CP), autoimmune pancreatitis (AIP) and pancreatic exocrine insufficiency (PEI); however, data on such an association remain sparse and heterogeneous.

METHOD

PubMed/MEDLINE and EMBASE databases were searched for studies investigating pancreatic involvement in patients with IBD.

RESULTS

Four thousand one hundred and twenty-one records were identified and 547 screened; finally, 124 studies were included in the review. AP is the most frequent pancreatic manifestation in IBD; the majority of AP cases in IBD are due to gallstones and drugs but cases of idiopathic AP are increasingly reported. AIP is a rare disease, but a strong association with IBD has been demonstrated, especially for type 2 and ulcerative colitis. The pathogenetic link between IBD and AIP remains unclear, but an immune-mediated pathway seems plausible. An association between CP and PEI with IBD has also been suggested, but data are to date scarce and conflicting.

CONCLUSION

This is the first systematic review of the association between IBD and pancreatic diseases. Gallstones and drugs should be considered the most probable causes of AP in IBD, with type 2 AIP also being possible.

New insights into the etiology, risk factors, and pathogenesis of pancreatitis in dogs: Potential impacts on clinical practice

While most cases of pancreatitis in dogs are thought to be idiopathic, potential risk factors are identified. In this article we provide a state‐of‐the‐art overview of suspected risk factors for pancreatitis in dogs, allowing for improved awareness and detection of potential dog‐specific risk factors, which might guide the development of disease prevention strategies. Additionally, we review important advances in our understanding of the pathophysiology of pancreatitis and potential areas for therapeutic manipulation based thereof. The outcome of pathophysiologic mechanisms and the development of clinical disease is dependent on the balance between stressors and protective mechanisms, which can be evaluated using the critical threshold theory.

The Characteristics and Risk Factors of Asparaginase-Associated Pancreatitis in Pediatric Acute Lymphoblastic Leukemia

OBJECTIVE

This study aimed to elucidate the characteristics and the risk factors for asparaginase-associated pancreatitis (AAP) in pediatric acute lymphoblastic leukemia (ALL) under the Taiwan Pediatric Oncology Group (TPOG)-ALL regimen.

METHODS

The study was conducted by reviewing the chart records of 191 patients aged 1 to 18 years treated with TPOG-ALL (2002 and 2013) protocols at the National Cheng Kung University Hospital, Tainan, Taiwan, from 2002 to 2019. The disease incidence, clinical presentations, laboratory data, complications, and outcomes of AAP were investigated.

RESULTS

The incidence of AAP was 4.7%. The incidence was significantly higher in children treated with the TPOG-ALL-2013 (n = 62) than TPOG-ALL-2002 (n = 129) protocol (11.3% vs 1.6%, P = 0.006). Multivariate analysis identified using TPOG-ALL-2013 protocol was an independent risk factor for AAP. Pancreatic necrosis or pseudocysts developed in 7 patients (78%). Notably, 1 AAP case (11%) developed diabetes mellitus and 4 (44%) had chronic pancreatitis during a 1-year observational period. None were mortality.

CONCLUSIONS

The incidence of AAP was 4.7% in ALL patients treated with TPOG-ALL protocol. Although a higher cumulative dose of asparaginase in TPOG-ALL-2013 may attribute to the pancreatic toxicity, unidentified factors such as genetic predisposition or other drugs still need further study.

Gut and liver involvement in pediatric hematolymphoid malignancies

Hematolymphoid malignancies are common neoplasms in childhood. The involvement of the gastrointestinal (GI) tract, liver, biliary system, pancreas, and peritoneum are closely interlinked and commonly encountered. In leukemias, lymphomas, and Langerhans cell histiocytosis (LCH), the manifestations result from infiltration, compression, overwhelmed immune system, and chemotherapy-induced drug toxicities. In acute leukemias, major manifestations are infiltrative hepatitis, drug induced gastritis, neutropenic typhlitis and chemotherapy related pancreatitis. Chronic leukemias are rare. Additional presentation in lymphomas is cholestasis due to infiltration or biliary obstruction by lymph nodal masses. Presence of ascites needs a thorough workup for the underlying pathophysiology that may modify the therapy and affect the outcome. Uncommon hematolymphoid malignancies are primary hepatic, hepatosplenic, and GI lymphomas which have strict definitions. In advanced diseases with extensive spread, it may be impossible to distinguish these diseases from the primary site of origin. LCH produces biliary strictures that mimic as sclerosing cholangitis. Liver infiltration is associated with poor liver recovery even after chemotherapy. The heterogeneity of gut and liver manifestations in hematolymphoid malignancies has a clinical impact on their management. Though chemotherapy is the mainstay of therapy in all hematolymphoid malignancies, debulking surgery and radiotherapy have an adjuvant role in specific clinical scenarios. Rare situations presenting as liver failure or end-stage liver disease require liver transplantation. At their initial presentation to a primary care physician, given the ambiguity in clinical manifestations and the prognostic difference with time-bound management, it is vital to recognize them early for optimal outcomes. Pooled data from robust registries across the world is required for better understanding of these complications.

Pancreatitis in Children

Pediatric pancreatitis describes a spectrum covering acute pancreatitis, acute recurrent pancreatitis, and chronic pancreatitis, each with varying clinical manifestations and risk factors requiring a tailored diagnostic approach. We emphasize management strategies based on age, risk factors, recurrence, and complications. A discussion of the role of therapeutic endoscopy is reviewed and highlights the growing role of endoscopic ultrasound and endoscopic retrograde cholangiopancreatography in children with pancreatitis. Particular diagnostic challenges in autoimmune pancreatitis are reviewed with an emphasis on differentiating this entity from alternate pancreaticobiliary pathologies. Finally, we explore a multidisciplinary approach to acute recurrent and chronic pancreatitis.

Frequency, Predisposing Factors, and Clinical Outcome of Azathioprine-Induced Pancreatitis Among Patients With Inflammatory Bowel Disease: Results From a Tertiary Referral Center

OBJECTIVE

The aim of the study was to identify the frequency of azathioprine-induced acute pancreatitis (AZA-AP) and related factors.

METHODS

Seven hundred eighty-seven inflammatory bowel disease (IBD) patients on AZA therapy were retrospectively analyzed. Azathioprine-induced AP was diagnosed with positive imaging and/or an at least 3-fold increased amylase level, in presence of typical abdominal pain. The AZA-AP group was compared with patients on AZA therapy with no history of pancreatitis and 4 numerical adjacent cases with the same diagnosis were selected (group B).

RESULTS

Fifty-four patients developed gastrointestinal symptoms (6.9%); however, only half of them (26 of 54) had pancreatitis, except 1, all within the first 2 months under AZA. When the AZA-AP group was compared with group B, only budesonide usage and active smoking were significantly more common in group A (46.2% vs 25%, P = 0.034, and 77% vs 51%, P = 0.017, respectively). Active smoking was the only independent risk factor for AZA-AP development (odds ratio, 3.208 [95% confidence interval, 1.192-8.632]).

CONCLUSIONS

All IBD patients developed AZA-AP nearly all within the first 2 months. Azathioprine intolerance may be a hidden diagnosis in at least half of the patients with AZA-AP symptoms. All smoker IBD patients should be monitored closely for AZA-AP development.

Use of thiopurines is not a risk factor for post-ERC pancreatitis in patients with primary sclerosing cholangitis

INTRODUCTION

Risk of post-ERC pancreatitis (PEP) in patients with primary sclerosing cholangitis (PSC) is 1-7.8%. PSC is often associated with inflammatory bowel disease and autoimmune hepatitis, which are usually treated with thiopurines. The role of thiopurines in PEP risk is still unclear.

AIMS AND METHODS

We evaluated the thiopurine use in PEP. The data of 354 PSC patients who underwent 985 ERCs between 2009 and 2018 were collected. 177 patients treated with thiopurines (study group, SG) and 177 controls (CG) were matched with a propensity score (PSM). Odds ratios (ORs) with 95% confidence interval (95% CI) were calculated. Multivariable logistic regression analysis and generalized linear mixed model were performed. The P-value <0.05 was significant.

RESULTS

In matched data, 472 ERCs were performed in SG and 513 in CG. Thiopurines were used in 373/472 (79.0%) ERCs in SG. The PEP rate was 5.3% in SG and 5.7% in CG (p = 0.889). Unintentional pancreatic duct cannulation (OR 1.28, 95%CI 1.07-1.51, p = 0.004), and periampullary diverticulum (OR 4.87, 95%CI 1.72-11.98, p = 0.001) increased the risk of PEP.

CONCLUSION

Prior or present thiopurine use did not increase the risk of PEP.

Acute pancreatitis following allogeneic hematopoietic stem cell transplantation in children

Acute pancreatitis (AP) is a potential complication of hematopoietic stem cell transplantation (HSCT), but its incidence and risk factors remain unclear. Thus, we reviewed the cases of 259 consecutive children who received allogeneic HSCT at our institution between January 2000 and December 2017 to determine the incidence and risk factors of AP. Thirteen patients developed AP during a median follow-up period of 4.4 years. The median time from HSCT to AP onset was 80 days (range 29-2426 days), and cumulative incidence (CI) at 4 years was 5.0% [95% confidence interval (95% CI) 2.7-8.3%]. The CI of AP was significantly higher in patients who received bone marrow or peripheral blood stem cells than in those who received cord blood (7.2% versus 0.0% at 4 years, P = 0.02) and was higher in patients who developed grade II-IV acute graft-versus-host disease (GVHD) than in those who did not (31.4% versus 1.4% at 4 years, P < 0.001). Multivariate analysis showed that grade II-IV acute GVHD was an independent risk factor for AP [hazard ratio 15.2 (95% CI 4.1-55.8), P < 0.001] and was strongly associated with post-HSCT AP in children.

Heroin-Induced Acute Pancreatitis

Heroin-induced pancreatitis (HIP) is rare with only a few cases reported previously in the literature and the pathophysiology mechanism is yet to be investigated. We present two cases of acute pancreatitis (AP) in the setting of acute heroin (diacetylmorphine) intoxication. Both patients presented with nausea, vomiting and severe abdominal pain after intranasal heroin use. On laboratory analysis were found to have elevated serum lipase, positive urine toxicology for opioids, without any other obvious causes for AP. Both patients had a full recovery with supportive treatment. As a general approach, drug-induced pancreatitis is a diagnosis of exclusion and a high index of suspicion is required when the most common etiologies are ruled out.

Acute Pancreatitis as a Complication of Antiepileptic Treatment: Case Series and Review of the Literature

Acute pancreatitis (AP) appears to be rare disease in childhood. In children, it has a different aetiology and course, and requires different management than in adult patients. The diagnosis of AP is based on at least two of the three criteria, which include typical clinical symptoms, abnormalities in laboratory tests and/or imaging studies of the pancreas. There are many known causes leading to AP in children including infections, blunt abdominal trauma, genetic factors, gallstone disease, metabolic disorders, anatomical defects of the pancreas, systemic diseases, as well as drugs, including antiepileptic drugs, and especially preparations of valproic acid. In our study, we present four cases of young patients diagnosed with acute pancreatitis as a complication of valproic acid therapy and we present a review of the literature. We believe that the activity of pancreatic enzymes should be monitored in children treated with valproate preparations in the case of clinical symptoms suggesting AP.

Acute Pancreatitis

Acute pancreatitis is one of the most common reasons for gastroenterology-related hospitalization in the United States. With significant morbidity and subsequent mortality related to both the acute presentation and subsequent sequelae, prompt diagnosis and appropriate management are critical, especially in the first 24 hours of illness. It is also important to accurately recognize complications, such as pancreatic fluid collections and vascular events, and identify a definitive cause so that a strategy to prevent future attacks can be implemented.

Loperamide Abuse and Its Sequelae

INTRODUCTION

Loperamide is an opioid available over the counter and in prescription form. Loperamide functions as a μ-agonist within the enteric nervous system to slow intestinal motility. Its antidiarrheal properties and primarily peripheral activity make loperamide an important tool in the management of inflammatory bowel disease.

CASE REPORT

A 42-year-old man was found unconscious in cardiac arrest, and emergency medical personnel restored normal sinus rhythm. Family reported complaints of abdominal pain and that he "went through a lot" of loperamide. In the emergency department, the patient exhibited symptoms consistent with an opioid overdose. Mental status improved after administration of naloxone, an opioid antagonist. An electrocardiogram revealed a prolonged QTc interval, which progressed into Torsades de Pointes rhythm during admission. The patient succumbed from hypoxic brain injury, and there was evidence of acute pancreatitis at autopsy. Loperamide and desmethylloperamide (loperamide metabolite) were detected in blood samples. Cause of death was ruled loperamide toxicity.

DISCUSSION

Because of reduced central nervous system activity and associated euphoria at therapeutic doses, loperamide abuse is rarely reported. This case demonstrates that an overdose on loperamide can occur in patients seeking symptom alleviation, and may mimic the presentation of opioid overdose.

Management of pancreatic pseudocysts in pediatric oncology patients

BACKGROUND

Management of children with pancreatic pseudocysts has historically been adopted from the adult experience where pancreatic pseudocysts greater than 6 cm are unlikely to resolve without intervention. We reviewed the clinical course of pediatric oncology patients with pancreatic pseudocysts.

METHODS

A retrospective review of patients treated over a 15-year period was performed. Variables evaluated included cancer type, medications administered, clinical and imaging characteristics of the pancreatic pseudocysts, treatment and outcome.

RESULTS

A total of 132 patients with a median age of 13 (IQR, 9-17) years were identified with pancreatitis. Thirty-one (23.5%) patients developed a pancreatic pseudocyst, of which 84% were associated with PEG-asparaginase treatment. The median pseudocyst size was 7.6 (IQR, 4.4-9.9) cm with 59% being greater than 6 cm. Twenty-two (71%) patients with a pancreatic pseudocyst underwent successful conservative management, while only 9 (29%) required procedural intervention including six percutaneous drainage, one of whom recurred and required surgical cyst-enteric drainage. Two other patients had primary surgical cyst-enteric drainage and one patient underwent endoscopic retrograde cholangiopancreatography with stenting. The indication for intervention was worsening pain rather than pseudocyst imaging characteristics, size or serum amylase/lipase.

CONCLUSION

Most medication-induced pancreatic pseudocysts in children being treated for cancer, regardless of pseudocyst size, can be managed non-operatively or with transgastric percutaneous drainage. The need for intervention can be safely dictated by patient symptoms.

LEVEL OF EVIDENCE

III.

Drug induced pancreatitis is the leading known cause of first attack acute pancreatitis in children

BACKGROUND/OBJECTIVES

Drug induced acute pancreatitis (DIAP) as one of the acute pancreatitis (AP) risks factors is a poorly understood entity. The aim of the current study was to compare the characteristics and course of DIAP cases in children presenting with a first attack of AP.

METHODS

Patients presenting with AP were included in a prospective database. We enrolled 165 AP patients that met criteria for inclusion. DIAP patients were included in that group if they were exposed to a drug known to be associated with AP and the rest were included in the non-drug induced-acute pancreatitis (non-DIAP) group.

RESULTS

DIAP was observed in 40/165 (24%) of cases, 24 cases had drug-induced as the sole risk factor, and 16 had DIAP with another risk factor(s). The two groups were similar in intravenous fluid and feeding managements, but ERCP was more commonly performed in the non- DIAP group, 14 (11%), vs 0% in the DIAP group, p = 0.02. Moderately severe [9 (23%) vs 11 (9%)] and severe AP [7 (18%) vs 6 (5%)] were more commonly associated with DIAP than non- DIAP, p = 0.001. DIAP was more commonly associated with ICU stay, 10 (25%), vs 12 (10%), p = 0.01, hospital stay was longer in DIAP median (IQR) of 6 (3.9-11) days vs 3.3 (2-5.7) days in non- DIAP, p = 0.001. The DIAP group had a significantly higher proportion of comorbidities (p < 0.0001).

CONCLUSIONS

DIAP is a leading risk factor for a first attack of AP in children and is associated with increased morbidity and severity of the pancreatitis course. DIAP warrants further investigation in future studies.

Posaconazole-Induced Acute Pancreatitis: A Rare Side Effect in a Child with Chronic Granulomatous Disease

Introduction: Pancreatitis is an inflammatory disease of the pancreas. Drug-induced pancreatitis is an important cause of pancreatitis. There are two pathological types of acute pancreatitis, including pancreatic edema with a mild course and pancreatic necrosis with a poor prognosis. Some agents can induce pancreatitis, but so far, posaconazole-induced pancreatitis in children has been not reported. Here, we describe the case of a child with acute pancreatitis who received posaconazole. Case Presentation: A 10-year-old girl with a three-year history of chronic granulomatous disease (CGD) was admitted to hospital due to epigastric pain, nausea, vomiting, loss of appetite, and fever for the last four days. The pain was persistent and prominent in the periumbilical area. The patient was on lifelong antifungal prophylaxis for her illness. On abdominal sonography, the head of the pancreas was inflated, which can indicate pancreatitis. All the medications were discontinued at the time of admission, and along with sufficient hydration, acetaminophen was administered for the patient’s pain. One, three, and twelve months after discharge, the patient was visited for follow-up with no signs of stomach discomfort, and the lab data was within the normal limits. CGD is a rare disease in which the phagocytes fail to produce hydrogen peroxide. Such patients are prone to bacterial and fungal infections. Conclusions: In conclusion, this is the second case of posaconazole-induced pancreatitis and the first case in children; thus, we recommend that physicians should be aware of the signs of pancreatitis in high-risk individuals like immunocompromised pediatric population.

Severe rhabdomyolysis and acute asymptomatic pancreatitis following the concomitant use of Biktarvy in the setting of hyperosmolar diabetic crisis

Biktarvy (bictegravir/emtricitabine/tenofovir alafemanide), which has been recently approved for the treatment of HIV, is a single-pill regimen that associates bictegravir and a novel integrase strand transfer inhibitor (INSTI) with a combination of two nucleoside reverse transcriptase inhibitors (NRTI) of emtricitabine and tenofovir alafemanide. Among treatment complications, rhabdomyolysis has been reported in association with some NRTI and INSTI but never with bictegravir. Acute pancreatitis has also been reported recently with another INSTI, dolutegravir. We report here a 62-year-old man with diabetes and HIV infection, and receiving Biktarvy for 1 month. He presented to the emergency department for muscular pain and fatigue. He was on treatment with Descovy (tenofovir alafenamide/emtricitabine) and Viramune (nevirapine) for 2 years but he recently asked for a regimen simplification. Severe rhabdomyolysis and acute pancreatitis were diagnosed. Although the aetiology of these events could be multifactorial, it cannot be ruled out that this episode could be linked to a potential side effect of bictegravir.

Ever-increasing diversity of drug-induced pancreatitis

With over 100000 hospital admissions per annum, acute pancreatitis remains the leading gastrointestinal cause of hospitalization in the United States and has far-reaching impact well beyond. It has become increasingly recognized that drug-induced pancreatitis (DIP), despite accounting for less than 3% of all cases, represents an important and growing though often inconspicuous cause of acute pancreatitis. Nevertheless, knowledge of DIP is often curtailed by the limited availability of evidence needed to implicate given agents, especially for non-prescription medications. Indeed, the majority of available data is derived from case reports, case series, or case control studies. Furthermore, the mechanism of injury and causality for many of these drugs remain elusive as a definitive correlation is generally not established (< 10% of cases). Several classification systems have been proposed, but no single system has been widely adopted, and periodic updates are required in light of ongoing pharmacologic expansion. Moreover, infrequently prescribed medications or those available over-the-counter (including herbal and other alternative remedies) are often overlooked as a potential culprit of acute pancreatitis. Herein, we review the ever-increasing diversity of DIP and the potential mechanisms of injury with the goal of raising awareness regarding the nature and magnitude of this entity. We believe this manuscript will aid in increasing both primary and secondary prevention of DIP, thus ultimately facilitating more expedient diagnosis and a decrease in DIP-related morbidity.

Acute pancreatitis associated with levofloxacin

According to some series, 0.3-1.5% of all cases of acute pancreatitis are drug induced. Acute pancreatitis due to levofloxacin is included in its safety data sheet as an adverse effect.

Psoriatic arthritis induced by anti-PD1 and treated with apremilast: a case report and review of the literature

Immune checkpoint inhibitors targeting programmed cell death protein 1 pathways are generally well tolerated, but immune-related adverse events have been observed in more than 80% of all patients. Rheumatic and musculoskeletal immune related adverse events have to date not been widely recognized or well characterized. Psoriasic arthritis is a rare entity and it makes management of patients difficult due to the limited therapeutic possibilities and the strong impact on the quality of life. The majority of cases were treated with glucocorticoids, in some cases not enough. We present the case of a patient with psoriasic arthritis and report cases described in literature of patients treated with apremilast, a small oral molecule that inhibits of phosphodiestherase 4.

Update on Hodgkin lymphoma from a radiologist's perspective

Recent advances in the management of Hodgkin lymphoma, due to new staging and response assessment systems as well as new therapies, have redefined the role of imaging for this disease. The purpose of this article is to provide radiologists with an update on the current role of imaging in Hodgkin lymphoma from diagnosis to assessment of treatment response, in view of the new staging and response assessment system and current treatment strategies.

Drug induced pancreatitis: A systematic review of case reports to determine potential drug associations

OBJECTIVE

A current assessment of case reports of possible drug-induced pancreatitis is needed. We systematically reviewed the case report literature to identify drugs with potential associations with acute pancreatitis and the burden of evidence supporting these associations.

METHODS

A protocol was developed a priori (PROSPERO CRD42017060473). We searched MEDLINE, Embase, the Cochrane Library, and additional sources to identify cases of drug-induced pancreatitis that met accepted diagnostic criteria of acute pancreatitis. Cases caused by multiple drugs or combination therapy were excluded. Established systematic review methods were used for screening and data extraction. A classification system for associated drugs was developed a priori based upon the number of cases, re-challenge, exclusion of non-drug causes of acute pancreatitis, and consistency of latency.

RESULTS

Seven-hundred and thirteen cases of potential drug-induced pancreatitis were identified, implicating 213 unique drugs. The evidence base was poor: exclusion of non-drug causes of acute pancreatitis was incomplete or poorly reported in all cases, 47% had at least one underlying condition predisposing to acute pancreatitis, and causality assessment was not conducted in 81%. Forty-five drugs (21%) were classified as having the highest level of evidence regarding their association with acute pancreatitis; causality was deemed to be probable or definite for 19 of these drugs (42%). Fifty-seven drugs (27%) had the lowest level of evidence regarding an association with acute pancreatitis, being implicated in single case reports, without exclusion of other causes of acute pancreatitis.

DISCUSSION

Much of the case report evidence upon which drug-induced pancreatitis associations are based is tenuous. A greater emphasis on exclusion of all non-drug causes of acute pancreatitis and on quality reporting would improve the evidence base. It should be recognized that reviews of case reports, are valuable scoping tools but have limited strength to establish drug-induced pancreatitis associations.

Safety of antithyroid drugs in pregnancy: update and therapy implications

Introduction: The thionamide antithyroid drugs, methimazole (MMI), its pro-drug derivative carbimazole (CMZ), and propylthiouracil (PTU) are the mainstay of treatment for hyperthyroidism in pregnancy. However, antithyroid drugs carry risks of adverse effects that can affect fetal and maternal well-being.Areas covered: This review provides an update on the safety of antithyroid drugs in pregnancy, focusing on the most serious concerns of severe liver disease and congenital anomalies.Expert opinion: PTU-induced liver disease is uncommon but can run a catastrophic course in pregnancy with a risk of liver failure and threats to maternal or fetal survival. Acute pancreatitis is a relatively rare occurrence that has been linked to thionamide use in a handful of reports in non-pregnant individuals. Observational studies on the risk of birth defects with antithyroid drug exposure in pregnancy overall show an increase in birth defect risk with exposure to CMZ/MMI, and to a lesser extent, PTU. Further studies are required to determine whether the currently recommended approach of switching between thionamide drugs in pregnancy improves outcomes. Ultimately, a preventative strategy of offering definitive therapy to hyperthyroid women of childbearing potential offers the best approach to truly reduce the risks of antithyroid drug adverse effects in pregnancy.

Treatment of Graves' hyperthyroidism with thionamides: a position paper on indications and safety in pregnancy

CONTEXT

Graves' disease affects 3% of women and 0.5% of men in the general population. The first line treatment of Graves' hyperthyroidism is based on the administration of antithyroid drugs (ATD), propylthiouracil (PTU), methimazole (MMI) and carbimazole. A recent warning from the Italian Drug Agency (Agenzia Italiana del Farmaco AIFA) reported the risk of MMI-induced acute pancreatitis. In addition, AIFA highlighted the possible association of MMI treatment during the first trimester of pregnancy with congenital malformations, thus recommending the use of effective contraceptive methods in women of childbearing age treated with MMI.

METHODS AND RESULTS

Revision of literature reported less than ten cases of the alleged MMI pancreatitis, allowing the inclusion of MMI in class III drug regarding the relative risk for drug-induced pancreatitis. Data available on the effect of hyperthyroidism per se on the risk of fetal malformations, although scanty, are sufficient to recommend treatment with ATD of the hyperthyroid pregnant woman. Case reports and population studies either suggesting or not suggesting MMI-induced fetal malformations do not allow unquestionable conclusions on this matter.

CONCLUSIONS

This consensus by experts from Italian Endocrine and Gynecologic Scientific Societies has edited recommendations derived form the available data and published guidelines of International Scientific Societies.

Acute Pancreatitis Associated With Cytarabine During the Treatment of Pediatric Acute Myeloid Leukemia

Pancreatitis is a common complication of many pediatric oncology drugs - most commonly asparaginase, followed by pentamidine, mercaptopurine, corticosteroids, and trimethoprim-sulfamethoxazole. Cytarabine-associated pancreatitis is not often mentioned in the pediatric oncology literature. We report the case of a 10-year-old female with acute myeloid leukemia who developed cytarabine-associated pancreatitis.

Incidence, Risk Factors, Outcomes, and Risk Score Model of Acute Pancreatitis after Allogeneic Hematopoietic Stem Cell Transplantation

Acute pancreatitis (AP) has been recognized as an uncommon yet potentially lethal complication after hematopoietic stem cell transplant (HSCT). This retrospective, nested, case-control study reviewed data from 5284 consecutive patients who underwent allogeneic (allo)-HSCT between 2009 and 2018 at a single center, identifying 40 patients (0.76%) with AP after allo-HSCT. The diagnosis and severity of AP were established and classified according to existing criteria. Younger age (P = .008), grades II to IV acute graft-versus-host disease (P = .010), a history of donor lymphocyte infusion (P = .033), and pre-existing gallstones (P = .003) were independent risk factors of AP after allo-HSCT. Post-transplant AP had a trend to negatively influence overall survival (OS) and nonrelapse mortality (NRM) (P = .063) for allo-HSCT recipients, but no significant difference was found. Patients with moderately severe and severe AP had significantly lower OS (P = .002) and higher NRM (P = .000) than other patients. Based on these findings, a risk score model was also established to predict the occurrence of AP. Our risk score model performed well in terms of discrimination when applied to derivation samples. Patients were classified into a low-risk group (0 to 1 point), a medium-risk group (2 to 3 points), and a high-risk group (4 points or more). Significant difference was observed in AP incidence among the 3 groups. The predictive tool explored by our study might contribute to target high-risk patients and guide personalized AP prevention in allo-HSCT recipients.

Advanced urothelial cancer: a radiology update

The recent genomic characterization of urothelial carcinoma by the Cancer Genome Atlas Project, made possible by the introduction of high throughput, reduced cost, and sequence analysis, has shed new insights on the biology of advanced disease. In addition, studies on imaging of advanced urothelial carcinoma have widened the knowledge on disease presentation and on pattern of metastatic spread and their correlation with the underlying biology of urothelial carcinoma. The wide range of treatments for advanced urothelial cancer, including combined chemotherapy regimens and immune checkpoint inhibitors, each result in treatment class-specific patterns of response and adverse events. Results of studies point to the need for a reliable biomarker, perhaps with imaging, that predicts prognosis and treatment response to systemic treatment, and can be used to select the most effective treatment while minimizing toxicity. This review of advanced urothelial cancer introduces the latest advances in genetic profiling, the current role of imaging, the radiographic appearance of treatment response and their toxicities, and details potential future areas of imaging research.

Congestive hepatopathy and acute pancreatitis as severe complications of mixed connective tissue disease

Mixed connective tissue disease (MCTD) causes multiple organ dysfunctions, such as joint swelling, pulmonary fibrosis and hypertension, and serositis, but hepatopancreatic complications are rare. Here, we report a case of young man who exhibited acute severe liver dysfunction. He also had impaired cardiac function: both ventriculi were hypokinetic, but pulmonary hypertension and pericarditis were not observed. Since his liver and cardiac function markedly improved after commencing furosemide and carperitide, we considered congestive hepatopathy due to MCTD and accompanying heart failure. Heart failure and congestive hepatopathy recurred and he was treated with diuretics and prednisolone, but he passed away by co-occurrence of acute hemorrhagic pancreatitis. Necropsy revealed chronic hepatic congestion but not accompanying autoimmune hepatitis and hepatic vasculitis. We should consider congestive hepatopathy and hemorrhagic pancreatitis as serious complications of MCTD.

Methods for the early detection of drug-induced pancreatitis: a systematic review of the literature

OBJECTIVES

We systematically reviewed the literature to identify evidence-informed recommendations regarding the detection of drug-induced pancreatitis (DIP) and, secondarily, to describe clinical processes for the diagnosis of DIP.

DESIGN

Systematic review.

DATA SOURCES

Ovid MEDLINE, including Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Embase Classic+Embase, the Cochrane Library.

ELIGIBILITY CRITERIA

We included clinical practice guidelines, systematic reviews, narrative reviews and observational studies with a focus of establishing incidence, prevalence or diagnostic approaches for DIP. Clinical trials that diagnosed DIP as an outcome were also included.

DATA EXTRACTION AND SYNTHESIS

Two reviewers screened citations and performed data extraction. A narrative synthesis of the evidence was prepared.

RESULTS

Fifty-nine studies were included. Early published evidence suggested serial pancreatic ultrasound could detect subclinical pancreatitis; however, subsequent studies demonstrated no utility of serial ultrasound or serial monitoring of pancreatic enzymes in the early detection of DIP. Two small studies conducted in patients with a high baseline risk of acute pancreatitis concluded serial monitoring of pancreatic enzymes may be useful to guide early discontinuation of medications with known associations with pancreatitis. Early discontinuation of medication was not advised for lower-risk patients because some medications cause transient elevations of pancreatic enzymes that do not progress to acute pancreatitis. Eight of 52 studies (15%) reporting a clinical diagnostic process for DIP reported using currently accepted criteria for the diagnosis of acute pancreatitis. A variety of methods were used to assess drug-related causality.

CONCLUSIONS

There is minimal evidence to support the use of serial monitoring by ultrasound or pancreatic enzymes to detect cases of DIP. Serial monitoring may be useful to guide early discontinuation of DIP-associated drugs in high-risk patients, but not in lower-risk patients. Greater uptake of standardised diagnostic and causality criteria for DIP is needed.

Pharmacovigilance Assessment of Drug-Induced Acute Pancreatitis Using a Spontaneous Reporting Database

Background:

Acute pancreatitis (AP) is associated with risks of morbidity and mortality. The incidence of AP recently increased compared to that traditionally reported in the literature.

Objective:

The purpose of this study was to evaluate the possible association between AP and drugs using the Japanese Adverse Drug Event Report (JADER) database, which is a spontaneous reporting database of adverse drug events.

Methods:

Adverse event reports submitted to the JADER database between 2004 and 2017 were analyzed. Disproportionality analysis was performed by calculating the reporting odds ratio (ROR) with 95% confidence intervals for signal detection.

Results:

A total of 3,443 reports (0.17% of all adverse events) were identified as drug-induced AP, in which 431 different drugs were involved. Acute pancreatitis was frequently reported in men (58.5%) in their 60s (19.1%); 40.6% developed AP within 4 weeks after the treatment. Among the most frequently reported drugs, signals were detected for prednisolone, ribavirin, sitagliptin, mesalazine, tacrolimus, and l-asparaginase, which are well-known causes of AP. Telaprevir, donepezil, and ustekinumab also generated signals. As for drugs with high RORs, l-asparaginase and alogliptin were noteworthy.

Conclusion:

Most of the identified drugs were already known to induce AP, but the likelihood of the reporting of AP varied among the drugs. Our results should raise physicians’ awareness of drugs associated with AP, but further investigation of these medications is warranted.

Metronidazole-Induced Pancreatitis: Is There Underrecognition? A Case Report and Systematic Review of the Literature

Introduction

Acute pancreatitis (AP) is the most common cause of gastroenterological hospitalization in the USA, with a mortality ranging from 5 to 20%. Up to 80% of cases are caused by cholelithiasis and alcohol abuse. Less common etiologies that need to be explored include hypertriglyceridemia, trauma, ERCP, infections, and drugs. A number of medications are known to cause acute pancreatitis, with 0.3-1.4% of all cases of pancreatitis being drug induced (DIP). Here, we present a case of metronidazole-induced acute pancreatitis.

Case Summary

A 60-year-old female presented with constant severe epigastric pain associated with nausea, vomiting, and anorexia for one day. She had no past medical history of alcohol use or hypertriglyceridemia and was s/p cholecystectomy in the distant past. Symptoms had begun three days after starting metronidazole for Clostridium difficile colitis. Lipase was > 396, and CT abdomen revealed peripancreatic fat stranding. She was diagnosed with AP, metronidazole was suspected to be responsible and hence stopped, and supportive management initiated. Her symptoms improved rapidly, and pancreatic enzymes normalized within 2 days. Of note, she had had an episode of acute pancreatitis 3 years ago, also following metronidazole use, with resolution at discontinuation of the drug. She had concurrently been on omeprazole during both episodes.

Discussion

Metronidazole is a commonly used antibiotic and is infrequently reported as a cause of DIP. Our review suggests the possibility of a dose-response and duration-response effect between metronidazole use and occurrence of pancreatitis. The most common presenting symptom and sign was moderate to severe epigastric pain and tenderness, accompanied by nausea/vomiting. Symptoms usually start within 2-7 days of starting the medication and usually resolve 2-5 days after discontinuation of therapy and pancreatitis treatment. The most common causative dose was 1-1.5 g/day. Our review also supports findings by Norgaard et al. suggesting that concurrent use of omeprazole potentiates the risk of metronidazole-induced pancreatitis.

Conclusion

Metronidazole is a commonly used antibiotic that may cause metronidazole-induced pancreatitis, especially if patients are concurrently taking PPIs. Awareness needs to be raised amongst clinicians regarding this association, in order to correctly identify etiology of pancreatitis and discontinue metronidazole promptly when suspected as the causative factor.

Acute management of pancreatitis: the key to best outcomes

Acute pancreatitis (AP) accounts for over 230 000 US and 28 000 UK hospital admissions annually. Abdominal pain is the most common presenting symptom in AP but may not reflect severity. The clinical challenge is identifying the 20% of patients in whom AP will be severe. We summarise the common aetiologies, the risk stratification strategies including the simplified Bedside Index for Severity in Acute Pancreatitis, acute management approaches in the initial presentation setting, conditions for using advance imaging and opinions on antibiotic use. Some warning signs of impending complications are also discussed.

The Effect of Concomitant Sirolimus and Propofol Therapy on Triglyceride Concentrations in Critically Ill Patients

BACKGROUND

Sirolimus and propofol are both independently associated with the development of hypertriglyceridemia (HTG) during therapy. To date, there are no published reports describing synergistic or additive drug interaction resulting in HTG with concomitant use of these medications.

STUDY QUESTION

To identify the occurrence of HTG in patients receiving concomitant sirolimus and propofol infusion therapy.

METHODS

Adult patients receiving sirolimus and a continuous propofol infusion for at least 12 hours from January 2005 to August 2009 were retrospectively evaluated. Data included Acute Physiology and Chronic Health Evaluation II score, weight, length of propofol therapy, and baseline triglyceride (TG) concentrations. The major outcome was incidence of HTG (TGs ≥500 mg/dL). Minor outcomes included the change in TG concentration from therapy initiation and manifestations of propofol-related infusion syndrome (PRIS).

RESULTS

Sixteen patients were included in the analysis, with 8 (50%) of the patients developing HTG. The patients in this case series had the following mean values: Acute Physiology and Chronic Health Evaluation II score of 20.2 ± 5.3, weight of 76.3 ± 21.2 kg, and baseline TG concentrations of 181.3 ± 89.7 mg/dL. Indications for sirolimus therapy included hematopoietic stem-cell transplantation (n = 15) and heart transplantation (n = 1). Mean length of propofol infusion was 99.8 ± 88.5 hours. The mean TG concentration during infusion was 515.6 ± 468.1 mg/dL. Fourteen (87.5%) patients had an increase of ≥100 mg/dL, 12 (75%) patients had an increase of ≥200 mg/dL, and 6 (37.5%) patients had an increase of ≥300 mg/dL in TG concentrations during therapy. Eleven patients developed one manifestation of PRIS, excluding HTG, and one patient had more than 2 new onset PRIS manifestations during propofol therapy.

CONCLUSIONS

Coadministration of propofol and sirolimus can potentially result in HTG, which may warrant more frequent monitoring. Further analysis is needed to examine the mechanism and clinical impact of this interaction.

Overview of systemic treatment in recurrent and advanced cervical cancer: a primer for radiologists

Imaging has a central role in surveillance of cervical cancer, guiding decision on when to initiate treatment for recurrent disease and to guide management in advanced cervical cancer. Due to the increased availability of pelvic radiation therapy, the rate of atypical presentation of recurrent disease has increased. Simultaneously, the array of systemic therapies now available for advanced cervical cancer has considerably expanded in the last few years, with therapies now available in mid and low-income countries. While pelvic recurrences are amenable of loco-regional treatment, recurrent disease may present with metastases to the thoracoabdominal organs, lymph nodes, bones, skin and brain, for which systemic treatment represent the standard of care. Besides combined chemotherapy regimens, alternative chemotherapies, biosimilars and immune checkpoint inhibitors are now available, each associated with a definite pattern of response and toxicity. In this review, after describing the typical and atypical presentations of recurrent and advanced cervical carcinoma on cross-sectional imaging, we will discuss systemic treatment for recurrent or advanced disease and their associated radiographic sequelae, in light of the newly available therapies.

Optimizing pegylated asparaginase use: An institutional guideline for dosing, monitoring, and management

The incorporation of L-asparaginase and pegylated asparaginase into pediatric-inspired regimens has conferred a survival advantage in treatment of adults with acute lymphoblastic leukemia. Use of asparaginase products requires careful prevention, monitoring, and management of adverse effects including hypersensitivity, hepatotoxicity, pancreatitis, coagulopathy, and thrombosis. Currently, there is limited published literature to offer guidance on management of these toxicities. At the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center, a standard of practice guideline was created to prevent and manage asparaginase-related adverse events. By sharing our long-term experience with asparaginase products and clinical management of asparaginase-induced toxicities, this article aims to improve patient safety and optimize treatment outcomes.

Acute pancreatitis associated with intravenous administration of propofol: evaluation of causality in a systematic review of the literature

Acute pancreatitis (AP) associated with intravenous administration of propofol has been described with unknown causal relation. We therefore assessed this causality in a systematic review. Multiple databases were searched on 16 August 2017; studies were appraised and selected by two reviewers based on a priori criteria. Propofol causality was evaluated with the Naranjo scale and Badalov classification.

We identified 18 studies from 11 countries with a total of 21 patients, and the majority had adequate methodological quality. The median age was 35 years (range, 4–77) and 10 (48%) were males. Overall, propofol was administrated in 8 patients as sedative along with induction/maintenance of anesthesia in 13 patients; median dose was 200 mg, with intermediate latency (1–30 days) in 14 (67%). Serum triglycerides were >1000 mg/dL in four patients. Severe AP was observed in four patients (19%). AP recurrence occurred in one out of two patients who underwent rechallenge. Mortality related to AP was 3/21(14%). Propofol was the probable cause of AP according to the Naranjo scale in 19 patients (89%).

Propofol-induced AP has a probable causal relation and evidence supports Badalov class Ib. Hypertriglyceridemia is not the only mechanism by which propofol illicit AP. Propofol-induced AP was severe in 19% of patients with a mortality rate related to AP of 14%. Future research is needed to delineate whether this risk is higher if combined with other procedures that portend inherent risk of pancreatitis such as endoscopic retrograde cholangiopancreatography.
