Abstract
Long-term medication with valproic acid has been associated with acute pancreatitis. The purpose of this report is to gain insight into the features of this pancreatitis. A preregistered literature search (CRD42023438294) was performed on the National Library of Medicine, Excerpta Medica, Web of Science, and Google Scholar. Patients with alcohol abuse disorder, gallstone disease, hypertriglyceridemia or hypercalcemia, patients with acute valproic acid intoxication, and patients with a pre-existing pancreatitis were excluded. For the final analysis, we retained 73 reports published between 1979 and 2023, which described 125 subjects (83 children and 42 adults predominantly affected by an epilepsy) with an acute pancreatitis related to valproic acid. The diagnosis was made 11 (3.0-24) months (median and interquartile range) after starting valproic acid. One hundred and five cases (84%) recovered and twenty (16%) died. Sex, age, dosage or circulating level of valproic acid, latency time, prevalence of intellectual disability, and antiepileptic co-medication were similar in cases with and without a lethal outcome. Nineteen subjects were rechallenged with valproic acid after recovery: sixteen (84%) cases developed a further episode of pancreatitis. In conclusion, pancreatitis associated with valproic acid presents at any time during treatment and has a high fatality rate.

Abstract
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.

Abstract
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.

Abstract
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. REGISTRATION CRD42017060473.

Abstract
Valproic acid (VPA) is still an important antiepileptic drug, with the broadest spectrum used in all types of seizures and syndromes. It has serious adverse effects such as hepatotoxicity, hyperammonemic encephalopathy, coagulation disorders, and pancreatitis. The incidence of VPA-associated pancreatitis has been estimated to be 1:40,000. We present a 6-year-old boy who developed acute pancreatitis (AP) and multiple-organ failure after 3 months of VPA therapy. The patient's laboratory values showed that his kidney and hepatic function had impaired and thrombocytopenia, and coagulopathy had developed. The patient's abdominal tomography showed a suspected appearance, which was consistent with pancreatitis. Because amylase and lipase levels were found to be high, AP was considered. The patient improved after cessation of VPA treatment. Ten days later, the patient recovered both clinically and laboratorial. Consequently, the patient was discharged with cure. In conclusion, AP is a rare, severe adverse reaction to VPA treatment. If a child, who is receiving VPA, develops abdominal pain and vomits, VPA-associated pancreatitis must be considered.

Abstract
We report a case of fungal pleural effusion secondary to presumed valproate induced pancreatitis with pseudocyst and stricture formation. A child with dyskinetic cerebral palsy who had been on sodium valproate for several years was transferred for drainage of a left sided pleural effusion. Pleural fluid culture consistently grew Candida glabrata although the patient was treated with broad-spectrum antibiotic and antifungal therapy. Clinical deterioration ensued with abdominal discomfort, feed intolerance, and re-accumulation of the effusion. Investigations revealed a large pancreatic pseudocyst compressing the stomach and impairing pancreatic function. Subsequent therapeutic evacuation of pancreatic fluid demonstrated C. glabrata. This case underscores that pleural disease may be secondary to abdominal pathology, and always to consider rare side-effects of medication in the face of a puzzling clinical picture.

Abstract
Valproic acid (VPA) is considered to be a drug of first choice and one of the most frequently-prescribed antiepileptic drugs worldwide for the therapy of generalized and focal epilepsies, including special epileptic. It is a broad-spectrum antiepileptic drug and is usually well tolerated. Rarely, serious complications may occur in some patients, including hemorrhagic pancreatitis, coagulopathies, bone marrow suppression, VPA-induced hepatotoxicity and encephalopathy, but there is still a lack of knowledge about the incidence and occurrence of these special side effects. Additionally, the consequences for VPA therapy and indication are more or less unclear. By literature review and own data this review addresses some of the challenges of VPA therapy and its side effects, which are not unique to epilepsy in childhood.

Abstract
Acute pancreatitis is rarely seen in children, and it is often drug induced. Valproic acid (VPA) is one of the most widely used anticonvulsants for children all over the world. We present 11-year-old boy developing pancreatitis after 6 months of therapy with VPA. The symptoms of pancreatitis subsided within 2 weeks after discontinuation of VPA. It seems that the prognosis of VPA-associated acute pancreatitis depends on early diagnosis, timely withdrawal of the offending agent and the treatment.

Abstract
The diagnosis of drug-induced acute pancreatitis often is difficult to establish. Although some medications have been shown to cause acute pancreatitis with a large body of evidence, including rechallenge, some medications have been attributed as a cause of acute pancreatitis merely by a single published case report in which the investigators found no other cause. In addition, some medications reported to have caused acute pancreatitis have obvious patterns of presentation, including the time from initiation to the development of disease (latency). There also appear to be patterns in the severity of disease. After reviewing the literature, we have classified drugs that have been reported to cause acute pancreatitis based on the published weight of evidence for each agent and the pattern of clinical presentation. Based on our analysis of the level of evidence, 4 classes of drugs could be identified. Class I drugs include medications in which at least 1 case report described a recurrence of acute pancreatitis with a rechallenge with the drug. Class II drugs include drugs in which there is a consistent latency in 75% or more of the reported cases. Class III drugs include drugs that had 2 or more case reports published, but neither a rechallenge nor a consistent latency period. Class IV drugs were similar to class III drugs, but only 1 case report had been published. Our analysis allows an evidence-based approach when suspecting a drug as causing acute pancreatitis.

Abstract
BACKGROUND Acute pancreatitis is rarely seen in children, and, in contrast to cases in adults, it is often drug induced. One possible medication is the antiepileptic drug valproic acid (VPA), which is commonly prescribed for generalized and focal epilepsy, migraine, neuropathic pain, and bipolar disorder. The common side effects associated with VPA are typically benign, but less common but more serious adverse effects may occur. These include hepatotoxicity, hyperammonemic encephalopathy, coagulation disorders, and pancreatitis. Since 1979, a few cases of pancreatitis induced by VPA have been published in the medical literature. METHODS We mailed a questionnaire to all members of the "German Section of the International League against Epilepsy," asking about VPA-induced side effects. We also reviewed the medical literature for VPA-induced pancreatitis. RESULTS Fifty-three publications (90 patients) published from 1979 to 2005 were found. Our survey in Germany, however, yielded 16 cases of pancreatitis from 1994 to 2003 whose original files we could study in detail. None of these patients had been published previously. CONCLUSIONS The difference between 90 patients reported worldwide from 1979 to 2005 and the 16 new documented cases from only Germany over 10 years corroborates that the occurrence of this severe side effect is under reported.
