Drug induced pancreatitis: A systematic review of case reports to determine potential drug associations. PLoS One 2020; 15:e0231883.

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
Drug-induced acute pancreatitis (DIAP) is a rare entity that is often challenging for clinicians. The aim of our study was to provide updated DIAP classes considering the updated definition of acute pancreatitis (AP) and in light of new medications and new case reports. A MEDLINE search (1950-2018) of the English language literature was performed looking for all adult (≥17 years old) human case reports with medication/drug induced as the cause of AP. The included case reports were required to provide the name of the drug, and diagnosis of AP must have been strictly established based on the revised Atlanta Classification criteria. A total of 183 medications were found to be implicated in 577 DIAP cases. A total of 78 cases were excluded because of minimal details or lack of definite diagnosis of AP. Drug-induced AP is rare, and most drugs cause mild DIAP. Only 2 drugs are well described in the literature to explain causation rather than association (azathioprine and didanosine). Larger case-control studies and a formal standardized DIAP reporting system are essential to study the true potential of the DIAP-implicated drugs described in this review.

Abstract
Although gallstone and alcohol use have been considered the most common causes of acute pancreatitis, hundreds of frequently prescribed medications are associated with this disease state. The true incidence is unknown since there are few population based studies available. The knowledge of drug induced acute pancreatitis is limited by the availability and the quality of the evidence as the majority of data is extrapolated from case reports. Establishing a definitive causal relationship between a drug and acute pancreatitis poses a challenge to clinicians. Several causative agent classification systems are often used to identify the suspected agents. They require regular updates since new drug induced acute pancreatitis cases are reported continuously. In addition, infrequently prescribed medications and herbal medications are often omitted. Furthermore, identification of drug induced acute pancreatitis with new medications often requires accumulation of post market case reports. The unrealistic expectation for a comprehensive list of medications and the multifactorial nature of acute pancreatitis call for a different approach. In this article, we review the potential mechanisms of drug induced acute pancreatitis and provide the perspective of deductive reasoning in order to allow clinicians to identify potential drug induced acute pancreatitis with limited data.

Abstract
This report describes a case showing histologic features of acute cholangitis with an over-the-counter drug. A 48-year-old woman was diagnosed with general malaise and progressive jaundice. A thorough review of her medical history revealed that the patient had taken an over-the-counter drug, Pabron Gold®, which she had used previously, that may have caused liver injury. Laboratory investigations revealed jaundice and liver dysfunction. Endoscopic retrograde cholangiography detected no extrahepatic biliary duct dilatation or stones. Liver biopsy indicated acute cholangitis involving neutrophils and eosinophils. Electron microscopy revealed fragmented nuclei, indicating that the degenerative bile duct-related epithelial cells were in an apoptotic process.

Abstract
Drug secretion into bile is typically considered a safe route of clearance. However, biliary delivery of some drugs or their reactive metabolites to the intestinal tract evokes adverse consequences due to direct toxic actions or indirect disruption of intestinal homeostasis. Biliary concentration of the chemotherapy agent 5-fluorodeoxyuridine (FUDR) and other compounds is associated with bile duct damage while enterohepatic cycling of antibiotics contributes to the disruptions of gut flora that produce diarrhea. The goal of this review is to describe key evidence that biliary delivery is an important factor in the intestinal injury caused by representative drugs. Emphasis will be given to 3 widely used drugs whose reactive metabolites are plausible causes of small intestinal injury, namely the nonsteroidal anti-inflammatory drug (NSAID) diclofenac, the immunosuppressant mycophenolic acid (MPA), and the chemotherapy agent irinotecan. Capsule endoscopy and other sensitive diagnostic techniques have documented a previously unappreciated, high prevalence of small intestinal injury among NSAID users. Clinical use of MPA and irinotecan is frequently associated such severe intestinal injury that dosage must be reduced. Observations from clinical and experimental studies have defined key events in the pathogenesis of these drugs, including roles for multidrug resistance-associated protein 2 (MRP2) and other transporters in biliary secretion and adduction of enterocyte proteins by reactive acyl glucuronide metabolites as a likely mechanism for intestinal injury. New strategies for minimizing the adverse intestinal consequences of irinotecan chemotherapy illustrate how basic information about key events in the biliary secretion of drugs and the nature of their proximate toxicants can lead to safer protocols for drugs.

Abstract
BACKGROUND AND AIMS Many frequently prescribed drugs are suspected to cause acute pancreatitis (AP). The goal of this paper is to bring to light the often occult but real problem of drug-induced pancreatitis (DIP). METHODS We searched the National Library of Medicine/Pubmed for reported cases of DIP from 1966 to April 30, 2004. Medications implicated in AP are classified based on the strength of evidence into one of three classes of drugs associated with pancreatitis. We reviewed the top 100 prescription medications in the United States for their association with AP. RESULTS Class I medications (medications implicated in greater than 20 reported cases of acute pancreatitis with at least one documented case following reexposure): didanosine, asparaginase, azathioprine, valproic acid, pentavalent antimonials, pentamidine, mercaptopurine, mesalamine, estrogen preparations, opiates, tetracycline, cytarabine, steroids, trimethoprim/sulfamethoxazole, sulfasalazine, furosemide, and sulindac. Class II medications (medications implicated in more than 10 cases of acute pancreatitis): rifampin, lamivudine, octreotide, carbamazepine, acetaminophen, phenformin, interferon alfa-2b, enalapril, hydrochlorothiazide, cisplatin, erythromycin, and cyclopenthiazide. Class III medications (all medications reported to be associated with pancreatitis). Of the top 100 most frequently prescribed medications in the United States, 44 have been implicated in AP, 14 of them fall into either Class I or II of medications associated with AP. CONCLUSIONS Among adverse drug reactions, pancreatitis is often-ignored because of the difficulty in implicating a drug as its cause. The physician should have a high index of suspicion for DIP, especially in specific subpopulations such as geriatric patients who may be on multiple medications, HIV+ patients, cancer patients, and patients receiving immunomodulating agents.

Abstract
PURPOSE Exisulind (sulindac sulfone, FGN-1, Aptosyn) is a sulindac metabolite that induces apoptosis via inhibition of cyclic GMP-phosphodiesterase. This agent demonstrated tumor growth inhibition in rodent models of colon, breast, prostate, and lung carcinogenesis. In an orthotopic model of human non-small-cell lung cancer, the combination of exisulind and docetaxel prolonged survival in athymic nude rats, forming the basis of this phase I combination study. EXPERIMENTAL DESIGN This study evaluated the toxicity and pharmacokinetics of combining exisulind (150-250 mg) given orally twice daily and docetaxel (30-36 mg/m2) administered intravenously on days 1, 8, and 15 of a 4-week cycle. RESULTS Twenty patients with a range of advanced solid tumors (median age, 59 years; age range, 35-77 years; median performance status, 1) received a total of 70 courses. Observed adverse events were mild to moderate, and there was no dose-limiting toxicity at any level. Grade 3 gastrointestinal toxicities were present in 10 of the 70 cycles (10%) and included nausea, vomiting, dyspepsia, and elevated alkaline phosphatase. Neutropenia was present in four cycles in patients treated with a docetaxel dose of 36 mg/m2. Pharmacokinetic analysis did not demonstrate a clear effect of exisulind on docetaxel pharmacokinetics and vice versa. Relationships were evident between the plasma concentration of exisulind and the development of grade 2 or greater toxicities. One third of patients maintained stable disease for 3 to 12 cycles, but no objective responses were observed. CONCLUSIONS The combination of docetaxel (36 mg/m2, weekly) and exisulind (500 mg/d) was reasonably well tolerated, and it is undergoing phase II testing in patients with non-small-cell lung cancer.

Abstract
Cholestasis caused by medicinal and chemical agents is an increasingly well-recognized cause of liver disease. Clinical drug-induced cholestatic syndromes producing jaundice and bile duct injury can mimic extrahepatic biliary obstruction, primary biliary cirrhosis, and sclerosing cholangitis, among others. This article updates the various forms of drug-induced cholestasis, focusing on the clinicopathologic features of this form of hepatic injury and on the known or putative mechanisms by which drugs and chemicals lead to cholestasis.

Abstract
BACKGROUND Dapsone can rarely cause a hypersensitivity reaction called dapsone syndrome, consisting of fever, hepatitis, exfoliative dermatitis, lymphadenopathy and hemolytic anemia. Dapsone syndrome is a manifestation of the DRESS (drug rash with eosinophilia and systemic symptoms) syndrome which is a serious condition that has been reported in association with various drugs. Cholangitis in dapsone syndrome has not been reported so far in the world literature. CASE PRESENTATION We report a patient who presented with fever, exfoliative dermatitis, jaundice and anemia within three weeks of starting of dapsone therapy. These features are typical of dapsone syndrome, which is due to dapsone hypersensitivity and is potentially fatal. Unlike previous reports of hepatitic or cholestatic injury in dapsone syndrome we report here a case that had cholangitic liver injury. It responded to corticosteroids. CONCLUSION We conclude that cholangitis, though unusual, can also form a part of dapsone syndrome. Physicians should be aware of this unusual picture of potentially fatal dapsone syndrome.

Abstract
NSAIDs are one of most frequently prescribed agents in clinical practice. Whereas hepatotoxicity is a rare complication of most NSAIDs (typically 1 to 10 per 100,000 persons exposed), the high level of usage means that these drugs cause liver disease. Because of their divergent chemical structures, the mechanisms and clinicopathological manifestations of hepatotoxicity vary widely. The reactive metabolite syndrome, in which serious rash, eosinophilia, and other forms of tissue injury are common, may be incited by several NSAIDs, including newer agents. Women, people aged more than 50 years, and for some drugs, the type of arthritis, may be risk factors for drug-induced liver injury. The spectrum of NSAID-drug related hepatotoxicity continues to expand, with reports of interactive toxicity in adults with hepatitis C and recognition of rare cases of liver disease associated with non-selective, selective, and preferential COX-2 inhibitors. Better outcomes require people taking NSAIDs to be aware of possible drug reactions involving the liver, and prescribers should be vigilant for early symptoms of hepatotoxicity so that incriminated agents are discontinued promptly.

Abstract
Drug-induced bile duct injury related prolonged or chronic cholestasis is recognized as a common side effect of treatment with several drugs. The severity and duration of the clinical symptoms suggest that this increase in number of reports is not only related to clinician and pathologists being increasingly aware of the condition, but also may represent a true increase in incidence likely related to a time-related growing experience with newer drugs. This clinical presentation encompasses a wide variety of features that may be the source of diagnostic difficulties, especially in the cases where cholestasis occurs days or weeks after the completion of therapy. Even more puzzling is the initial picture of hepatocholangitis, which may be silent and ensuing bile duct paucity with chronic anicteric cholestasis may be another source of diagnostic difficulties in the long-term. These diagnostic difficulties suggest that some of the cases of the so-called "idiopathic adulthood ductopenia" may originate from overlooked drug induced vanishing bile duct syndrome. The pathogenesis of the syndrome remains largely unknown and the determinants of prognosis and outcome. From reproducible data obtained in different studies investigating HLA-dependent predisposition, one may assume that genetics plays a major role even if other unknown additive factors are also likely involved. Severity of initial hepatocholangitis is likely to represent another important determinant of severity and prognosis, however to be assessed in larger longitudinal studies. Therapy of large bile duct injury mimics that of primary sclerosing cholangitis. Treatment of small bile duct injury remains disappointing. Corticosteroids are invariably ineffective. Ursodeoxycholic acid as been shown to induce improvement of clinical and biochemical cholestasis in some selected cases, its efficacy being however unpredictable. Preliminary data about the natural history of the vanishing bile duct syndrome suggest that therapy might be more effective when initiated early.

Abstract
OBJECTIVE To report a case of acute cholestatic hepatitis associated with the selective cyclooxygenase-2 inhibitor celecoxib. CASE SUMMARY A 41-year-old white man was hospitalized for jaundice after 2 doses of celecoxib 200 mg for pain associated with right-knee trauma. Laboratory workup showed hyperbilirubinemia, mildly elevated serum transaminase concentrations, and cholestasis. Abdominal imaging showed no dilation of the biliary tree. Histology showed cholestasis, with bile plugs in dilated bile canaliculi and a mild portal infiltrate that are highly suggestive of drug-induced cholestasis. DISCUSSION This is the fourth report in the English-language literature describing cholestatic hepatitis temporally related to celecoxib use, the second supported by histologic findings typical of drug-induced cholestasis, and the first in a patient who denied use of alcoholic beverages and was taking no other drugs or herbal products at the time of the reaction. The Naranjo probability scale indicated that celecoxib was a probable cause of acute cholestatic hepatitis in this patient. CONCLUSIONS Cholestatic hepatitis is a well-recognized adverse effect of several drugs. Although celecoxib is considered to have a very low potential for hepatic toxicity, well-documented reports of adverse reactions can contribute significantly to the definition of more accurate safety profiles for new drugs introduced into clinical practice.

Abstract
OBJECTIVES In 30% of patients with primary biliary cirrhosis (PBC) ursodeoxycholic acid (UDCA) causes full biochemical normalization, while 70% are incomplete responders. The only differences between the two groups are the significantly higher cholestasis indices in the incomplete responders. In these patients we investigated whether the strongly choleretic sulindac together with UDCA is superior to UDCA monotherapy. DESIGN AND METHODS Twenty-three patients with PBC incompletely responding to UDCA monotherapy were entered in the open label study for 12 months. Eleven patients (stage II, seven; III, two; and IV, two) received UDCA (10-15 mg/kg/day) plus sulindac (100-300 mg/day) (Group I). Twelve patients (stage I, six; II, four; III, one; and IV, one) were treated with UDCA alone (Group II). Liver biochemistry, analysis of antimitochondrial, antinuclear, smooth muscle, and liver-kidney-microsomal antibodies, ultrasonography and gastroscopy were done in regular intervals. RESULTS In Group I all liver indices, IgG, IgM and IgA significantly improved although pretreatment data and stages of the disease tended to be higher than in Group II. In five patients of Group I liver histology improved slightly. Sulindac was well tolerated. The biochemical indices did not further improve on UDCA monotherapy. CONCLUSIONS Sulindac in combination with UDCA further improves liver biochemistries in patients with PBC who responded incompletely to UDCA alone.

Abstract
Primary biliary cirrhosis is the prototype of the small-duct biliary diseases which are characterized by damage or destruction of interlobular and proximal septal bile ducts. Autoimmune cholangitis differs serologically from primary biliary cirrhosis but, by current consensus, has the same pathological features. The histological findings in primary biliary cirrhosis and the staging criteria of that disease are well described and at this point can be applied to autoimmune cholangitis also. Diagnostic difficulties arise either because other small-duct biliary diseases are not considered or because tell-tale histological signs, particularly ductopenia, are not recognized. Review of all small-duct biliary diseases suggests that interlobular and adjacent septal bile ducts (1st and 2nd generation ducts) represent an immunosensitive portion of the biliary tree. Comparative studies of these unique segments may have important implications for our understanding of primary biliary cirrhosis and autoimmune cholangitis and possibly for future treatment options for these conditions.

Abstract
OBJECTIVE Drugs are considered a rare cause of acute pancreatitis. We conducted a descriptive study to assess which drugs have been associated with acute pancreatitis in spontaneous adverse drug reaction reports in The Netherlands. METHODS Our study is based on reports of drug-associated acute pancreatitis reported to the Netherlands Center for Monitoring of Adverse Reactions to Drugs and The Netherlands Pharmacovigilance Foundation LAREB between 1 January 1977 and 1 January 1998. We used an algorithm to validate the diagnosis and to assess the causal relationship between acute pancreatitis and use of the suspected drug. RESULTS A total of 55 cases were available for review. We excluded 11 (20.0%) reports, as we could not confirm the diagnosis of acute pancreatitis. Another 10 (18%) cases were excluded, as the causal relationship with the suspected drug was unlikely. In the remaining 34 reports, acute pancreatitis was labeled as definite in 11 (32%) and as probable in 23 (68%). The age of the patients ranged from 17 to 84 yr with a median of 41; 24 (71%) patients were female. Of the 34 cases, 27 (79%) recovered, five (15%) died, and in two (6%) the outcome is unknown. Azathioprine, cimetidine, interferon-alpha, methyldopa, metronidazole, olsalazine, and oxyphenbutazon all had a definite causal relationship with acute pancreatitis. Doxycycline, enalapril, famotidine, ibuprofen, maprotiline, mesalazine, and sulindac had a probable causal relationship with acute pancreatitis. CONCLUSIONS A variety of drugs was associated with acute pancreatitis in Dutch adverse drug reaction reports. Quantitative information about drug-induced pancreatitis is scanty. Epidemiological studies to assess the risk of drug-induced acute pancreas, therefore, are needed.

Abstract
Cholestasis resulting from drugs is an increasingly recognized cause of liver disease. It produces a broad clinical-pathologic spectrum of injury that includes simple jaundice, cholestatic hepatitis, and bile duct injury that can mimic extrahepatic biliary obstruction, primary biliary cirrhosis, and sclerosing cholangitis. Although the risk of drug-induced cholestasis leading to a fatal outcome is quite rare, knowledge and recognition of the various forms of cholestatic injury assumes an importance whenever clinicians are confronted with jaundice or other manifestations of liver disease in patients receiving medicinal or chemical agents.

Abstract
Few data exist about the incidence of drug-induced pancreatitis in the general population. 20 cases of drug-related pancreatitis were reported in Switzerland over a period of 12 years. The proportion of cases of pancreatitis caused by drugs is estimated to be around 2% in the general population, with much higher proportions in specific subpopulations, such as children and patients who are HIV positive. The literature about drug-induced pancreatitis consists mainly of anecdotal case reports. Clear evidence of a definite association with pancreatitis, by means of rechallenge tests, or consistent case reports, supported by animal experiments or data on the incidence of acute pancreatitis in drug trials exists for didanosine, valproic acid (sodium valproate), aminosalicylates, estrogen, calcium, anticholinesterases and sodium stibogluconate. An association with drug-induced pancreatitis is likely but not definitely proven for thiazide diuretics, pentamidine, ACE inhibitors, asparaginase, vinca alkaloids, some nonsteroidal anti-inflammatory drugs and clozapine. Pancreatitis is possibly caused by azathioprine, furosemide (frusemide), tetracycline, metronidazole, isoniazid, rifampicin (rifampin), sulphonamides, cyclosporin and some antineoplastic drugs. Many drugs have been reported to be associated with acute pancreatitis. However, lack of rechallenge evidence, consistent statistical data, or evidence from experimental studies on a possible mechanism prohibit definitive conclusions about most of them. The high incidence of concurrent illnesses known to induce acute pancreatitis, makes a trigger role or co-factor role for the drug seem most likely.

Abstract
BACKGROUND Recent emphasis on nonsteroidal anti-inflammatory drug (NSAID)-associated hepatic injury blurs differences between NSAIDs. Accordingly, examination of hepatic injury by individual NSAIDs seemed warranted. Sulindac-associated hepatic injury was selected. METHODS From 338 reports submitted to the Food and Drug Administration, 247 were considered inadequate or unconvincing for sulindac toxicity. The remaining 91 cases of reactions to the drug were analyzed. In 15 there was histological material available. RESULTS There were four deaths, three attributed to severe hypersensitivity and one to fulminant hepatic failure. Two thirds of the cases had clinical hallmarks of hypersensitivity. The ratio of females to males was 3.5:1; 69% of the patients were over 50 years of age. Jaundice was recorded in 67% of the patients. The pattern was cholestatic in 43%, hepatocellular in 25%, mixed in 12%, and indeterminate in 20% of the patients. Eosinophilia was significantly more frequent in patients with cholestatic injury (40%) than in those with hepatocellular injury (0). CONCLUSION Sulindac injury involves females more than males. It can lead to cholestatic or hepatocellular injury, most often because of immunological idiosyncrasy. In some patients, metabolic idiosyncrasy may be the mechanism. This study illustrates the utility of analysis of adverse reaction reports in characterizing drug-induced injury.
