Protons pump inhibitor treatment and lower gastrointestinal bleeding: Balancing risks and benefits

Proton pump inhibitors(PPIs) represent a milestone in the treatment of acid-related diseases, and are the mainstay in preventing upper gastrointestinal bleeding in high-risk patients treated with nonsteroidal antiinflammatory drugs(NSAIDs) or low-dose aspirin. However, this beneficial effect does not extend to the lower gastrointestinal tract. PPIs do not prevent NSAID or aspirin-associated lower gastrointestinal bleeding(LGB). PPIs may increase both small bowel injury related to NSAIDs and low-dose aspirin treatment and the risk of LGB. Recent studies suggested that altering intestinal microbiota by PPIs may be involved in the pathogenesis of NSAID-enteropathy. An increase in LGB hospitalization rates may occur more frequently in older patients with more comorbidities and are associated with high hospital resource utilization, longer hospitalization, and increased mortality. Preventive strategies for NSAID and aspirin-associated gastrointestinal bleeding should be directed toward preventing both upper and lower gastrointestinal damage. Future research should be directed toward identifying patients at low-risk for gastrointestinal events associated with the use of NSAIDs or aspirin to avoid inappropriate PPI prescribing. Alternatively, the efficacy of new pharmacologic strategies should be evaluated in high-risk groups, with the aim of reducing the risk of both upper and lower gastrointestinal bleeding in these patients.

NSAIDs and the gastrointestinal tract

NSAIDs incur significant gastrointestinal (GI) side effects. The complication risk increases with history of peptic ulcer or older age. Helicobacter pylori infection and cardioprotective aspirin have independent and additive risks in the presence of NSAID use. NSAID enteropathy is increasingly recognized. Cardiovascular and GI risk stratification and H. pylori infection testing should be done before initiating NSAIDs. An NSAID combined with a proton pump inhibitor (PPI) is comparable to cyclooxygenase (COX)-2 inhibitors for gastroprotection, but for high-risk patients, COX-2 plus PPI should be considered. Aspirin and COX-2 inhibitors are associated with reduced colon adenoma risk, but higher dose and longer duration of treatment with aspirin appears effective. Hence, patients at high risk of colorectal cancer (with significant family or personal history of premalignant adenoma) must be identified, and cardiovascular and GI risk must be assessed before using these agents as chemopreventive drugs.     

Primary prevention of coronary heart disease with aspirin

According to the meta-analysis and the results of the two studies with the highest power, aspirin is effective in primary prevention of coronary heart disease. These beneficial effects, however, are at least partially outweighed by unwanted effects-such as intense gastrointestinal bleeding and hemorrhagic stroke. These side effects remain constant with increasing risk of coronary heart disease, whereas the protective effects increase. If an annual risk of coronary heart disease of < or = 0.6% exists, aspirin is normally not indicated; for a risk of 0.7-1.4% the facts should be discussed with the patient. If a risk of > or = 1.5% exists, aspirin should be given.     

Care of the elderly with gastrointestinal problems in family practice

Gastrointestinal problems in older people cause a great amount of anxiety, morbidity and mortality. In general these diseases present for the first time to family practitioners. The management of gastrointestinal problems is more difficult because in an older age group, functional diseases can present in the same way as organic diseases. In addition, family practitioners see a different kind of patient than speciality physicians and may not have immediate access to diagnostic investigations. In this chapter, the role of the family practitioner in screening for gastrointestinal problems in asymptomatic older people is explored. In addition, how they differentiate between organic and non-organic disease and refer appropriately to secondary care is discussed. The role of family practitioners in the on-going maintenance of gastrointestinal diseases and in the management of Helicobacter pylori in community dwelling older people is also considered.

Problems of aspirin therapy--such as "aspirin paradox" and "aspirin resistance"--have been documented for secondary prevention; they might, however, have likewise clinical implications in primary prevention.     

Naproxen in juvenile chronic polyarthritis.

Naproxen at 10 mg per kg body weight was compared with aspirin at 80 mg per kg body weight in children suffering from juvenile chronic polyarthritis. It was found to be as effective as aspirin, with certainly no more and possibly fewer gastrointestinal side effects. A long-term tolerance study up to 12 months confirmed that naproxed was a satisfactory nonsteroidal anti-inflammatory drug in the management of various types of juvenile chronic arthritis.     

Minidose Aspirin and Gastrointestinal Bleeding—A Retrospective,Case–Control Study in Hospitalized Patients

Low or minimal doses of aspirin are widely used for prevention of cardiovascular diseases. Aspirin is known to produce severe adverse gastrointestinal effects, such as bleeding and perforation. Less is known about the risk associated with minidose aspirin. Our aim was to assess the possible association of upper gastrointestinal tract bleeding with minidose aspirin therapy. A retrospective controlled design was used. Patients hospitalized for melena or hematemesis between January 1, 2000, and December 31, 2001, were identified by ICD-9 codes, and their clinical findings were compared to these of patients without upper gastrointestinal bleeding hospitalized during the same period and matched for age and sex. Bleeding was attributed to therapy if patients used a nonsteroidal anti-inflammatory drug or aspirin therapy within 30 days before hospitalization. The study group included 318 patients (59% male), and the control group 141 (65% male). Mean ages were 67 ± 19 and 64 ± 19 years, respectively. Study patients had more accompanying diseases, used more medications, and required more blood transfusions than controls (37%, vs. 2% of controls; P < 0.001). Minidose aspirin was used by 28% of the study group and 18% of the controls (P = 0.03). The average dose was 40 ± 86 and 21 ± 55 mg/day, respectively (P = 0.012). Only 26% of the study patients received a gastric protective agent. On multivariate analysis, aspirin consumption was the only independent risk factor for upper gastrointestinal tract bleeding. There appears to be an association between minidose aspirin treatment and hospitalization for upper gastrointestinal tract bleeding. Despite the advanced age of the patients, only one-quarter were treated with gastric protective agent.

Risks of clinically significant upper gastrointestinal events with etodolac and naproxen: a historical cohort analysis

BACKGROUND AND AIMS: Etodolac is a generic nonsteroidal anti-inflammatory drug (NSAID). Previous in vitro studies have shown that etodolac is a selective inhibitor of cyclooxygenase (COX)-2 with selectivity in between that of other COX-2 inhibitors such as celecoxib and rofecoxib. However, there are no outcomes data assessing clinically significant upper gastrointestinal (CSUGI) events with etodolac. METHODS: A historical cohort study was performed at the Dallas Veterans Affairs Medical Center in which 16,286 veteran patients (5596 patient-years) received etodolac or naproxen during a 3-year period without concurrent use of other ulcerogenic drugs other than low-dose aspirin. The primary outcome was the CSUGI event rate of the etodolac and naproxen groups without concomitant low-dose aspirin. RESULTS: The incidence of CSUGI events was .78% and .24% for naproxen and etodolac, respectively. In the NSAID-naive subset, the incidence of CSUGI events was .99% and .24% for naproxen and etodolac, respectively. Compared with naproxen, etodolac was associated with a reduction in upper gastrointestinal events, corresponding to an odds ratio of .39 (95% confidence interval, .20-.76; P = .006). Concomitantly used low-dose aspirin increased event rates with naproxen 2-fold and etodolac 9-fold. Hence, there was no significant difference in gastrointestinal event rates between etodolac and naproxen when low-dose aspirin was taken concomitantly. CONCLUSIONS: Etodolac is a generic COX-2 selective inhibitor that reduces CSUGI events compared with the nonselective NSAID naproxen. However, concomitant use of low-dose aspirin negates the gastrointestinal safety advantages of etodolac.     

Clinical features of gastroduodenal injury associated with long-term low-dose aspirin therapy

Low-dose aspirin(LDA) is clinically used for the prevention of cardiovascular and cerebrovascular events with the advent of an aging society.On the other hand,a very low dose of aspirin(10 mg daily) decreases the gastric mucosal prostaglandin levels and causes significant gastric mucosal damage.The incidence of LDAinduced gastrointestinal mucosal injury and bleeding has increased.It has been noticed that the incidence of LDA-induced gastrointestinal hemorrhage has increased more than that of non-aspirin non-steroidal anti-inflammatory drug(NSAID)-induced lesions.The pathogenesis related to inhibition of cyclooxygenase(COX)-1 includes reduced mucosal flow,reduced mucus and bicarbonate secretion,and impaired platelet aggregation.The pathogenesis related to inhibition of COX-2 involves reduced angiogenesis and increased leukocyte adherence.The pathogenic mechanisms related to direct epithelial damage are acid back diffusion and impaired platelet aggregation.The factors associated with an increased risk of upper gastrointestinal(GI) complications in subjects taking LDA are aspirin dose,history of ulcer or upper GI bleeding,age > 70 years,concomitant use of non-aspirin NSAIDs including COX-2-selective NSAIDs,and Helicobacter pylori(H.pylori) infection.Moreover,no significant differences have been found between ulcer and non-ulcer groups in the frequency and severity of symptoms such as nausea,acid regurgitation,heartburn,and bloating.It has been shown that the ratios of ulcers located in the body,fundus and cardia are significantly higher in bleeding patients than the ratio of gastroduodenal ulcers in patients taking LDA.Proton pump inhibitors reduce the risk of developing gastric and duodenal ulcers.In contrast to NSAIDinduced gastrointestinal ulcers,a well-tolerated histamine H2-receptor antagonist is reportedly effective in prevention of LDA-induced gastrointestinal ulcers.The eradication of H.pylori is equivalent to treatment with omeprazole in preventing recurrent bleeding.Continuous aspirin therapy for patie     

The mechanisms of aspirin-intolerant asthma and its management

Aspirin is one of the most widely used medications in the world. Adverse effects related to aspirin use were described almost concurrently with its first use. The most common side effects are gastrointestinal and renal, but adverse respiratory effects are not uncommon, and approximately 10% of adult asthmatics are aspirin intolerant. Many of these patients present with the so-called aspirin triad of aspirin sensitivity, chronic rhinosinusitis with associated nasal polyposis, and severe asthma. This paper provides a review of recent investigations into the pathogenesis of this process, which have furthered our understanding of the mechanisms and management of aspirin-induced asthma.     

Platelet receptor redox regulation

A large number of patients require antiplatelet therapy (mainly aspirin and/or clopidogrel). Recent studies suggest that the combination of these agents is useful in patients with acute coronary syndrome and after percutaneous coronary intervention with stent placement. On the other hand, bleeding complications, most of which arise from the upper gastrointestinal (UGI) tract, can limit the use of antiplatelet drugs. Clopidogrel appears to be associated with fewer UGI side effects and bleeding compared with aspirin. However, a history of previous UGI bleeding is a major risk factor for clopidogrel-associated bleeding. The use of proton-pump inhibitors (PPIs) decreases the rate of UGI bleeding in patients receiving aspirin or clopidogrel. Furthermore, a recent study suggested that the administration of low-dose aspirin plus high-dose esomeprazole (a potent PPI) was associated with fewer episodes of UGI bleeding than clopidogrel alone in patients with a history of recent UGI haemorrhage. However, this study had several limitations and its results should be cautiously extrapolated into clinical practice. The combination of aspirin plus clopidogrel increases the risk of UGI bleeding. Unfortunately, there are no data on the effect of PPI prophylaxis in this setting. Available evidence suggests that where aspirin and/or clopidogrel are to be started or continued in patients with a recent history of UGI ulceration or bleeding (after ulcer healing and eradication of H. pylori infection), treatment with a PPI is a useful precaution. The patients should also be carefully monitored for recurrence of UGI bleeding.

Left ventricular systolic dysfunction and atrial fibrillation in older people in the community--a need for screening?

BACKGROUND: Heart failure and stroke are major causes of morbidity and mortality in older people. Angiotensin converting enzyme inhibitors improve symptoms and survival in left ventricular systolic dysfunction. Anticoagulants are effective in stroke prevention in atrial fibrillation with aspirin being a less effective alternative. OBJECTIVES: To determine the prevalence of left ventricular systolic dysfunction, health services utilisation and prescribing of diuretics and angiotensin converting enzyme inhibitors in left ventricular systolic dysfunction, and the prevalence of atrial fibrillation and anti-platelet/thrombotic therapy in atrial fibrillation in older people in the community. METHODS: 500 subjects were drawn by two-stage random sampling from 5,002 subjects aged 70 years and over living at home. Subjects were screened for atrial fibrillation and left ventricular systolic dysfunction using electrocardiography and echocardiography. RESULTS: The population prevalence amongst older people of left ventricular systolic dysfunction was 9.8% and of atrial fibrillation 7.8%. More than two-thirds of those with left ventricular systolic dysfunction were not on angiotensin converting enzyme inhibitors. Of those in atrial fibrillation, 35% were taking aspirin, 24% were taking warfarin and 41% were on neither aspirin nor warfarin. Nearly 90% of older people in the community have had contact with their general practitioner over the past year, and over half of those with left ventricular systolic dysfunction have had contact with hospital-based services over the past 2 years. CONCLUSIONS: Left ventricular systolic dysfunction is under-treated in older people in the community. Despite the high level of contact with hospital and community-based services, the majority of those with systolic left ventricular dysfunction are not on angiotensin converting enzyme inhibitors and a significant proportion of those in atrial fibrillation are not on any treatment for stroke prevention.
