Drug-induced pancreatitis (lisinopril)

Another Case of Lisinopril-Induced Acute Pancreatitis

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

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.

Hypertriglyceridemia-Associated Drug-Induced Acute Pancreatitis

OBJECTIVES

The aim of our study was to investigate the cases of drug-induced acute pancreatitis (DIAP) with hypertriglyceridemia as the mechanism of injury.

METHODS

A MEDLINE search (1963-2018) of the English language literature was performed looking for all human case reports of adults (>18 years old) with hypertriglyceridemia as the mechanism of DIAP. The latest search date was February 28, 2018. Drugs were classified into probability groups based on a classification used by Badalov et al (Clin Gastroenterol Hepatol. 2007;5:648-661).

RESULTS

The search revealed a total of 76 cases in 59 published reports. A total of 25 medications were found to be implicated in DIAP secondary to hypertriglyceridemia mechanism. Most of acute pancreatitis cases were mild or moderately severe with favorable outcomes. In 3 cases involving tamoxifen, pagaspargase, and quetiapine, patient death was the outcome. Plasmapheresis was only used in 9 cases in an effort to decrease triglyceride levels.

CONCLUSIONS

Hypertriglyceridemia-associated DIAP is a rare phenomenon, and the current systematic review provides a summary of drugs that have been implicated in this phenomenon, which allow physicians to be oriented about this adverse effect when these drugs are used.

Lisinopril-induced acute pancreatitis

Drugs are an uncommon but well-recognised cause of acute pancreatitis and new agents of drug-induced pancreatitis continue to be reported. We describe only the 10th reported case of lisinopril-induced pancreatitis in a young female patient.

Severe acute pancreatitis in China: etiology and mortality in 1976 patients

OBJECTIVES

Many epidemiological studies have recently been published on acute pancreatitis; however, there is no known published report on pancreatitis in China. The present study aims to assess the etiology and mortality of severe acute pancreatitis in China.

METHODS

Fifteen medical centers located throughout mainland China were involved in this retrospective study. The medical records of 1976 patients, who were admitted to these centers with the diagnosis of severe acute pancreatitis from December 1990 to December 2005, were reviewed. Epidemiological, laboratory, radiological, and therapeutic data for each case were collected on a standardized form for analysis. Severity of pancreatitis was graded according to established criteria.

RESULTS

Of the 1976 patients (1028 men, 948 women; mean age, 56.2 +/- 16.5 years; range, 9-94 years). Biliary tract disease (58.7%) was the main etiologic factor, whereas in 25.2%, the cause was identified as idiopathic. Endotherapy was performed in 9.1% of the severe biliary cases, but only in 33%, it was performed within 72 hours. The mean duration of hospitalization was 22.5 +/- 21.4 days, and the overall mortality rate was 11.8%.

CONCLUSIONS

In this retrospective study, biliary tract disease was the main etiologic factor of severe acute pancreatitis in China. The highest mortality occurred in severe idiopathic pancreatitis, and there was no clear relationship between mortality and age.

Drug-induced acute pancreatitis: an evidence-based review

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.

A case of simvastatin-associated pancreatitis and review of statin-associated pancreatitis

Reduction of low-density lipoprotein cholesterol (LDL) concentration has become the primary goal and a standard of care in the practice of cholesterol management. The 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, or statins, are the most frequently prescribed lipid lowering agents on the market. As more information is learned through the results of clinical trials, LDL goals become more stringent and difficult to attain. Large doses of high-potency statins, sometimes given in combination with other lipid-lowering agents, are frequently necessary to achieve these goals. As a result, the frequency of adverse effects from statin therapy may be expected to increase, and less common adverse effects may occur more often. As statins are used more aggressively, rare and possibly dangerous adverse effects must be identified, especially those that are becoming more frequently encountered. Increased awareness may lead to earlier diagnosis and management of diseases that may be caused by the statins. We describe a 58-year-old man who was hospitalized with idiopathic pancreatitis 4 months after starting simvastatin therapy. His oral drug therapy was withheld, and he was treated with bowel rest. The patient was discharged on hospital day 5, and his oral drug regimen, including simvastatin, was resumed. He was admitted again 16 months later with a second diagnosis of acute pancreatitis and was discharged after 3 days of bowel rest with no oral drug therapy. Simvastatin was restarted on discharge, but the patient stopped taking it after experiencing muscle soreness and weakness in his arms. He recalled having similar arm pain that preceded the previous episode of acute pancreatitis. All other causes of the pancreatitis had been ruled out; thus, the correlation between simvastatin-induced myalgia and onset of acute pancreatitis on two separate occasions made simvastatin the suspected instigating agent. Pancreatitis is a rare adverse effect of statin therapy, but it has been documented in several case reports involving most of the statins. Continued reporting is necessary to increase awareness of this rare adverse effect of simvastatin so that it may be promptly managed or avoided in the future.

Identification of pancreatitis in the ambulatory setting

Acute pancreatitis can be life threatening. As a nurse practitioner, you are expected to accurately diagnose, treat, and refer as necessary. Because many different types of disease can cause abdominal pain, it is prudent to know signs, symptoms, and risk factors for pancreatitis. After reviewing this article, nurses should have a better understanding of acute pancreatitis and be able to recognize when it strikes.
