Gastrointestinal bleeding in the elderly

Acute upper and lower gastrointestinal bleeding management in older people taking or not taking anticoagulants: a literature review

Acute upper and lower gastrointestinal (GI) bleeding may be a potentially life-threatening event that requires prompt recognition and an early effective management, being responsible for a considerable number of hospital admissions. Methods. We perform a clinical review to summarize the recent international guidelines, helping the physician in clinical practice. Older people are a vulnerable subgroup of patients more prone to developing GI bleeding because of several comorbidities and polypharmacy, especially related to an increased use of antiplatelet and anticoagulant drugs. In addition, older patients may have higher peri-procedural risk that should be evaluated. The recent introduction of reversal strategies may help the management of GI bleeding in this subgroup of patients. In this review, we aimed to (1) summarize the epidemiology and risk factors for upper and lower GI bleeding, (2) describe treatment options with a focus on pharmacodynamics and pharmacokinetics of different proton pump inhibitors, and (3) provide an overview of the clinical management with flowcharts for risk stratification and treatment. In conclusion, GI is common in older patients and an early effective management may be helpful in the reduction of several complications.

Acute, nonvariceal upper gastrointestinal bleeding

PURPOSE OF REVIEW

Acute, nonvariceal upper gastrointestinal bleeding (UGIB) is a common medical emergency encountered worldwide. Despite medical and technological advances, it remains associated with significant morbidity and mortality.

RECENT FINDINGS

Rapid patient assessment and management are paramount. When indicated, upper endoscopy in patients presenting with acute UGIB is effective for both diagnosis of the bleeding site and provision of endoscopic hemostasis. Endoscopic hemostasis significantly reduces rebleeding rates, blood transfusion requirements, length of hospital stay, surgery, and mortality. Furthermore, early upper endoscopy, defined as being performed within 24 h of patient presentation, improves patient outcomes.

SUMMARY

A structured approach to the patient with acute UGIB that includes early hemodynamic resuscitation and stabilization, preendoscopic risk stratification using validated instruments, pharmacologic and endoscopic intervention, and postendoscopy therapy is important to optimize patient outcome and assure efficient use of medical resources.

Upper gastrointestinal bleeding in elderly patients in a Tunisian hospital: A retrospective study

BACKGROUND AND STUDY AIMS

The older age group presents a major problem in the management of acute gastrointestinal bleeding with a relatively high mortality. The study aims to describe the background characteristics, causes and outcome of acute upper gastrointestinal bleeding in the elderly in Tunisia.

PATIENTS AND METHODS

We retrospectively reviewed data of 401 patients aged≥60 years presenting with upper gastrointestinal bleeding. Information collected included history, physical examination findings, laboratory data, endoscopic findings and length of hospital stay. Patients were divided into two groups: group A (65-79 years) and group B (>79 years).

RESULTS

Group A included 315 patients and group B 86 patients. There was a male preponderance in both groups. Co-morbidity (p<0.01) and use of non-steroidal anti-inflammatory drugs (NSAIDs) or anti-platelet drugs (p<0.01) were more common in group B. Oesophagitis was the cause of bleeding in 38.37% in group B, as compared with 19% in group A. The main cause of bleeding in group A was peptic ulcer. Rebleeding (6/86) and emergency surgery (1/86) were rare in group B and not different from those in group A. However, the bleeding-related mortality in the very elderly group was higher (13.9% vs. 4.76%; p=0.02). In multivariate analysis, only shock on admission was independently related to mortality (p=0.02).

CONCLUSION

Oesophagitis is the major cause of upper gastrointestinal haemorrhage in the very elderly patients. While rebleeding and emergency surgery rates are relatively low, the bleeding-related mortality was higher in the very elderly group.

Long-term follow-up and predictive factors of recurrence of anemia in a cohort of 102 very elderly patients explored for iron-deficiency anemia

AIM

To evaluate long-term follow-up and predictors of relapse of anemia in a cohort of 102 very elderly patients previously explored for iron-deficiency anemia (IDA).

METHODS

One hundred and two patients [61 women and 41 men, mean age 82+/-5.8 y (75 to 98)] explored for IDA were prospectively followed up from inclusion (June 2003 to May 2005) until death or May 2006. Survival rate was estimated by the Kaplan-Meier method and compared by the log-rank test. Predictors of recurrence of anemia were identified by multivariate analysis in the 4 following subgroups: unexplained IDA (subgroup 1, n=27), benign lesion (subgroup 2, n=37), cancer treated curatively (subgroup 3, n=28), cancers treated palliatively (subgroup 4, n=10).

RESULTS

Median follow-up was 20 months. At baseline, main clinical and laboratory data were not significantly different in the 4 subgroups, especially as regards severe comorbidities. Thirty-three patients died, 10 (30%) of them in the first month. Ten (100%) belonged to subgroup 4 versus, respectively, n=7 (26%), n=8 (22%), and n=8 (29%) of patients from subgroups 1, 2, and 3 (P<0.001). No death was directly related to recurrence of anemia. Survival rate at 1 year was 10% in subgroup 4, significantly lower than the other 3 subgroups (subgroup 1: 84%; subgroup 2: 86%; subgroup 3: 78%; log-rank test, P<0.0001). Anemia recurred in 18 cases, and required red cell transfusion in 13 cases. Predictive factors of recurrence of anemia [odds ratio (confidence interval 95%), P] were cancers treated palliatively [14.9 (3-72), P<0.01] and angiodysplasias [4.5 (1.1-18.2), 0.035].

CONCLUSIONS

In a cohort of very elderly patients explored for IDA, the mortality rate and the long-term survival were not different for patients with IDA related to a cancer treated curatively than those with unexplained IDA and those with IDA related to a benign lesion. Angiodysplasias and cancers treated palliatively were associated with recurrence of anemia. These results suggest interventionist strategies (including endoscopic investigation and appropriate surgery) for elderly patients with IDA.

Management and predictors of early mortality in elderly patients with iron deficiency anemia: a prospective study of 111 patients

OBJECTIVES

Iron deficiency anemia (IDA) is common in the elderly. It usually results from gastrointestinal (GI) bleeding and requires endoscopic exploration of the gastrointestinal tract. The aim of this prospective study in elderly patients was to evaluate the feasibility of endoscopy, the therapeutic impact, and identify predictors of early mortality.

METHODS

From June 2003 to May 2005, all patients over 75 years, hospitalized for anemia were screened for iron deficiency. Clinical (including serious comorbidities), biological, endoscopic and therapeutic data were collected. One month after treatment, a follow-up was carried out to assess the tolerance of such investigation and treatment.

RESULTS

One hundred and eleven patients (69 women, 82.3 +/- 6.4 years) had IDA, 102 (92%) underwent an upper endoscopy and 91 (82%) a colonoscopy. Nine (8%) patients were not investigated because of poor clinical condition (N=4) or dementia (N=5). Of the 75 (68%) patients with an identified source of bleeding, 12 (11%) had a synchronous lesion, 43 (39%) a colorectal source including 31 (72%) colorectal cancer, and 44 (40%) an upper GI source. Sixty-nine (92%) of the 75 patients received at least one of the following treatments: medical (N=27), endoscopic (N=20), and surgical (N=31). Surgery was curative in 28/31 (90%) cases of which 25/27 were colorectal cancers. One month after treatment, overall mortality was 11/111 (10%) and 4/31 (13%) after surgery. Predictors of early mortality (Odd ratio, 95% Confidence Interval) were: a malign cause (42; 3-588), no specific treatment (34; 3-423), at least 2 co-morbidities (20; 1-400).

CONCLUSION

In an unselected hospitalized population of elderly patients with IDA, endoscopy was generally feasible, allowing identification of a source of bleeding, especially colorectal cancer. A specific treatment was usually possible and proved curative without increase in early mortality.

Acute lower gastrointestinal hemorrhages in geriatric patients

Age is a risk factor in acute lower gastrointestinal hemorrhages (LGIH). The objectives here were to analyze: (1) diagnostic and therapeutic handling, (2) related morbidity and mortality, (3) the indications for surgery, and (4) the evolution of acute LGIH in patients > or =80 years. Forty-three patients >80 years with acute LGIH were reviewed retrospectively. In 86% (n = 37) related comorbidities were found, in 9% (n = 4) there had been prior colorectal surgery, 19% (n = 8) were antiaggregated, and 7% (n = 3) were anticoagulated. One hundred thirty-two cases of acute LGIH in patients <80 years were used as a control group. Student's t test and the chi-square test were applied. On arrival at the emergency ward 11 cases (26%) had hemodynamic instability and 8 of these were stabilized using conservative measures. In 39 cases an endoscopy was performed, allowing for an etiological diagnosis in 59% (n = 23) of cases, above all in those carried out in an urgent or semiurgent way. The arteriography permitted an etiological diagnosis in two of the four cases in which it was carried out. In seven patients (16%) urgent surgery was indicated: three were hemorrhoidectomies, three were subtotal colectomies, and one was a resection of the small intestine. The morbidity rate was 10% (n = 4) in the patients who were not treated and 14% (n = 1) in those treated, with a mortality rate of 8% (n = 3) and 14% (n = 1), respectively. The rate of relapse of bleeding after discharge from hospital was 42% (n = 18), with nine of these needing to be readmitted into hospital. In comparison with the control group, they present a different bleeding etiology (diverticulosis as opposed to the benign anal-rectal and small intestinal pathology in the younger population; P = 0.017), surgery is indicated with less frequency (9 versus 33%; P = 0.007), and there is a higher relapse rate (42 versus 26%; P = 0.045). Acute LGIH in geriatric patients relents in most cases with the use of conservative measures, although there is a high percentage of related morbidity and mortality, and of relapse of bleeding.

Gastrointestinal diseases in the elderly

PURPOSE OF REVIEW

The subject of gastrointestinal disorders in the elderly is timely and important because of the demographic reality that soon over 20% of our population will be older than 65 years of age, utilizing perhaps 50% of our total healthcare costs. The purpose of this review is to draw attention to some areas of clinical information that point in the direction of better clinical care for the elderly. Medicine is finally advancing from the era when most symptoms in older patients were ascribed to the aging process itself. Indeed, within gastroenterology there are few changes that occur inevitably as part of aging.

RECENT FINDINGS

Progress has been made in several areas of gastrointestinal pathophysiology. These include: the pathophysiology of swallowing and evacuation disorders and the beginning of the application of techniques derived from physiological studies to improve function; recognizing the importance of reflux esophagitis and its complications and improving treatment; understanding the importance of disorders of malabsorption and their impact upon nutrition in the elderly; major issues in the diagnosis and management of inflammatory bowel disease in this age group; and approaches to the prevention and treatment of gastrointestinal cancer, particularly colorectal cancer.

SUMMARY

As we pay more attention to these areas and encourage clinical research we expect to improve the treatment of older patients with these diseases and to reduce the burden of morbidity in this population.
