Prevalence of, and risk factors for, upper gastrointestinal tract bleeding in critically ill pediatric patients.

OBJECTIVE: To determine the occurrence of, and risk factors for, the development of upper gastrointestinal (GI) tract bleeding in critically ill pediatric patients. DESIGN: Prospective, descriptive, comparative study. SETTING: ICU in a tertiary care pediatric hospital affiliated with a university. PATIENTS: All patients < 19 yrs of age who were admitted to the ICU for a 4-month period (n = 429) were eligible for inclusion. A total of 221 patients were excluded for reasons listed below. Thus, 208 patients were studied. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: Patients were evaluated for overt upper GI bleeding as indicated by coffee ground material or bright red blood in gastric aspirates or black, tarry stools. Excluded were patients who were transferred out of the ICU within 24 hrs of admission, were receiving medications that would alter their risk for upper GI bleeding, or had a GI tract surgical procedure. Patients were categorized by diagnoses and analyzed for relative risk for upper GI bleeding. Of the 208 patients included, 25% had evidence of upper GI bleeding. There was no association between upper GI bleeding and age, weight, race, or sex. Diagnoses independently associated with an increased risk for upper GI bleeding were: circulatory shock, an operative procedure > or = 3 hrs in duration, and trauma. No clinically important sequelae were directly attributable to upper GI bleeding in this group of patients; however, intervention with antacids and histamine-2 receptor (H-2) antagonists likely decreased the progression of GI bleeding. CONCLUSIONS: Overt evidence of upper GI bleeding is not uncommon in critically ill pediatric patients. Certain diagnoses or risk factors may predispose these patients to develop upper GI bleeding.

Characterization of gastrointestinal bleeding in severely ill hospitalized patients.

OBJECTIVE: To characterize the source of bleeding and the prognosis in critically ill patients with upper gastrointestinal hemorrhage that developed while in the hospital. SETTING: Intensive care units of a large academic tertiary-care center. DESIGN: Retrospective cohort study. SUBJECTS: Patients undergoing endoscopy in intensive care units for gastrointestinal bleeding that developed while in the hospital. MEASUREMENTS AND MAIN RESULTS: Medical records were available for 142 patients. Of these, 66 met the criteria for in-hospital bleeding. Peptic ulcer disease, present in 56% of patients, was the most common bleeding source identified. Of patients with peptic ulcer disease, nine of 37 (24%) had stigmata of recent hemorrhage. Ten patients (15%) received endoscopic hemostasis interventions (eight receiving therapy for bleeding ulcers, two receiving therapy for esophageal varices). The in-hospital mortality rate was 42%. The cause of death was sepsis and/or multiple system organ failure in 21 patients (75%); the gastrointestinal bleeding may have contributed to the onset of sepsis in one of these patients. No patients died directly of gastrointestinal bleeding. CONCLUSIONS: Critically ill patients who bleed while in the hospital have similar sources of bleeding and rates of endoscopically directed therapy as patients admitted to hospital with bleeding. The mortality rate is very high in patients with bleeding that develops in the hospital, and this is usually a result of systemic disease. These data may help clinicians and patients to estimate the potential benefit of urgent endoscopy in critically ill patients.

Acute bleeding complications in patients after bone marrow transplantation.

Acute bleeding is a frequent complication that commonly associates with increased morbidity after bone marrow transplantation. Except for diffuse alveolar hemorrhage and cerebral hemorrhage, bleeding is infrequently recorded as a direct cause of death. Yet outcome analyses showed that bleeding from any reviewed site was associated with reduced survival. Reduced survival was correlated with bleeding intensity and the number of bleeding sites. These data point to the need to monitor all manifestations of bleeding, as bleeding may identify patients at risk for bone marrow transplantation toxicity. Until recently, prophylactic platelet transfusions were commonly given at a trigger of 20 x 10(9)/L. Whereas bleeding is more likely to occur when platelet counts drop to low levels, most bleeding episodes were recorded with platelet counts greater than 20 x 10(9)/L, suggesting causes other than profound thrombocytopenia in the pathogenesis of bleeding. Given that a trigger of 10 x 10(9)/L has become accepted for prophylactic platelet transfusions, care should be taken to ensure that parameters other than the incidence of bleeding have not been adversely affected.

Bleeding patterns after immediate initiation of an oral compared with a vaginal hormonal contraceptive.

OBJECTIVE: This study compared 84-day bleeding patterns after immediate initiation of a triphasic oral contraceptive with a 25-mug daily dose of ethinyl estradiol (E2) compared with the contraceptive vaginal ring, which has a 15-mug daily dose of ethinyl E2. METHODS: This was an open-label controlled trial. We randomly assigned 201 women to immediate start of a contraceptive pill or immediate start of the ring in a 1:1 allocation ratio. Our primary outcome was difference in mean bleeding-spotting days per woman according to treatment assignment. Secondary outcomes were differences in World Health Organization-defined menstrual indices, differences in perceived bleeding changes, and differences in bleeding according to cycle day at the start of method. RESULTS: The mean bleeding-spotting days in the 84-day reference period for all subjects was 19.2 days (17.0 days for ring users and 21.4 days for pill users, mean difference 4.4 days). Using the World Health Organization menstrual indices, the ring users experienced fewer days or episodes of bleeding-spotting and shorter intervals. Among ring users, no baseline characteristics were associated with bleeding outcomes. Older nulliparous pill users, however, reported more bleeding-spotting days. Significantly more ring users reported a decrease in duration of bleeding compared with pill users (P < .01). We found no significant differences in bleeding patterns based on analysis of cycle day at study enrollment. CONCLUSION: Our study shows advantageous bleeding patterns for subjects using the contraceptive vaginal ring. It also confirms our previous findings that immediate start of hormonal contraception is an acceptable alternative to waiting for menses. LEVEL OF EVIDENCE: II-1.

Catheter-induced vasospasm in the treatment of acute lower gastrointestinal bleeding.

PURPOSE: To demonstrate results in managing lower gastrointestinal (GI) bleeding with the use of superselective catheterization and intentional induction of vasospasm of the bleeding vessel without the use of embolic agents or vasospasm-inducing medications. MATERIALS AND METHODS: A retrospective review of 15 episodes of lower GI bleeding treated in the past 6 years by intentional catheter-induced vasospasm (CIV) to achieve thrombosis of a bleeding source was conducted. Nine patients had angiographically proven inferior mesenteric artery bleeding and six had angiographically proven superior mesenteric artery bleeding. RESULTS: Bleeding was stopped initially in all patients after effective treatment of the feeding artery. Only one patient experienced a repeat episode of bleeding 2 days later, which required hemicolectomy. Two other patients who underwent adequate embolization underwent surgery at the discretion of the surgeon involved. The remainder were clinically observed and discharged after return of stable vital signs and hematocrit levels. None of the patients treated had clinically evident intestinal ischemia or infarction. There was one significant repeat incidence of bleeding 2 months after CIV that may have represented recurrent bleeding from the original site. CONCLUSION: CIV may be a safe and effective first-line method of embolizing known lower GI bleeding. Whether CIV is used as primary therapy or as the result of spasm incurred during superselective catheterization, the patient may be regarded as successfully treated and followed accordingly, thereby possibly avoiding acute surgical therapy.

Initial management of massive oral bleeding after midfacial fracture.

BACKGROUND: This article reviews initial outcomes of the treatment of massive oral bleeding after midfacial fracture. METHODS: Massive bleeding was defined according to the criteria of Buchanan and Holtmann. The incidence of patients who met these criteria, hematocrit, the type of fracture, time from injury to initial management, source of bleeding, duration of management, and treatment strategy were recorded. RESULTS: We identified massive bleeding in the maxillofacial region in 5 of 521 patients (0.96%). All patients demonstrated profuse bleeding from the nose, and no active source of bleeding was evident in the oral cavity. Bleeding was controlled by nasal packing and temporary reduction in all patients, none of whom required artery ligation or embolization. CONCLUSION: Massive oral bleeding associated with midfacial fractures is frequently derived from the nasal cavity and associated structures. Although the nose may be the cause of the bleeding, the sinuses, skull base, and nasopharynx may also have active bleeding that has cleared through the nasal cavity and nasopharynx into the oral cavity. Control of this massive nasal bleeding during the early stage can therefore improve morbidity associated with severe exsanguination.

Main clinical manifestations of a bleeding diathesis: an often disregarded aspect of medical and surgical history taking.

A suitable clinical evaluation of a bleeding diathesis is often forgone. The young doctor is often unprepared to describe in an accurate way the different types of bleeding. An adequate classification and adequate clinical information about a bleeding diathesis are instead of paramount importance. Bleeding may be cutaneous, mucous, articular, muscular, parenchymal, intracavitary, orificial. Each of these sites and forms may have diagnostic implications. An accurate description of the several forms of cutaneous bleeding (petechiae, purpuric spots, ecchymosis, haematomas, etc.) is needed for referrals and for controls. The correct evaluation of cutaneous bleeding manifestations of children (battered child syndrome) is absolutely important for clinical and medico-legal purposes. The same is true for the battering syndrome seen in women abused by their spouses. The grading of haemarthrosis in haemophilia patients is important for the follow-up. A proper description of haematuria is essential in suggesting the probable site of bleeding (kidney or bladder or urethra). A proper evaluation of bleeding may give also useful information on the general health status of the patients (presence of anaemia, poor nutrition, renal insufficiency, etc.). The combination of bleeding and thrombosis in the same patient is also a clinical challenge. The relationship between haemorrhage and thrombosis may be sequential or concomitant. Sequential thrombosis may occur in a patient confined in bed for a brain haemorrhage. Concomitant thrombosis and bleeding occur in DIC and in patients with thrombosis being treated with anticoagulants. Finally, it should be kept in mind that a proper evaluation of the bleeding diathesis of a given patient may help the caring doctor in ordering appropriate laboratory tests (e.g. a platelet count for petechiae, a PTT for a patient with haemarthrosis, etc.).

Bleeding complications to oral anticoagulant therapy: multivariate analysis of 1010 treatment years in 551 outpatients.

One thousand and ten patient years of oral anticoagulant therapy with vitamin-K-antagonists were reviewed with regard to major bleeding complications. The incidence of bleeding that necessitated hospital admission was 2.7% per year (95% confidence limits, 1.7-3.7%). The major source of bleeding was the alimentary tract, whereas no cases of intracranial bleeding were found. Various factors with potential effects on the bleeding risk were evaluated by multivariate statistical analysis, and the following independent risk factors were identified: age greater than 75 years and hypertension increased the bleeding risk by 10.5% and 4.5%, respectively. Each recorded prothrombin value significantly below the therapeutic range increased the bleeding risk by 3.9%, and each year of treatment increased the risk by 2.0%. These figures may be used to estimate the risk of major bleeding in an individual patient. Current treatment with thiazide diuretics was found to increase the bleeding risk by 5.2%. However, this observation requires further documentation and analysis. Although no lethal episodes of bleeding occurred, the developing field of indications for oral anticoagulant therapy should be considered on the basis of a continuous substantial risk of major bleeding.

Treatment with proton pump inhibitors in acute non-variceal upper gastrointestinal bleeding: a meta-analysis.

Medical therapy is an attractive adjuvant to endoscopic treatment in upper gastrointestinal (UGI) bleeding. This review aims to assess the treatment effects of proton pump inhibitor (PPI) therapy in acute non-variceal UGI bleeding. Outcome measures evaluated were further bleeding, surgery, all-cause deaths, ulcer deaths and non-ulcer deaths. We searched MEDLINE (1966-2002) and EMBASE (1974-2002) using the terms 'gastrointestinal hemorrhage', 'peptic ulcer hemorrhage', 'proton pump inhibitor', 'omeprazole', 'pantoprazole', 'lansoprazole', 'rabeprazole' and 'esomeprazole'. The search was extended to the Cochrane controlled trials registry database, published abstracts from five international gastroenterology conferences, manufacturers of PPI, known contacts and bibliographies from each full-length published report. We included trials published in English and non-English languages. Eligible studies were randomized controlled trials that compared the treatment effects of PPI therapy with placebo or H2 receptor antagonists in patients with acute non-variceal UGI bleeding. Of the 175 articles screened, 26 controlled trials including 4670 subjects (2317 in treatment arm and 2353 in control arm) were analyzed. The methodology, population, intervention, and outcomes of each selected trial were evaluated using duplicate independent review. Disagreements were resolved by consensus. PPI therapy significantly reduced rates of further bleeding (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40-0.57) and surgery (OR, 0.61; 95% CI, 0.48-0.76). All-cause deaths were unaffected (OR, 1.02; 95% CI, 0.76-1.37). Ulcer deaths showed a significant reduction (OR, 0.58; 95% CI, 0.35-0.96), while non-ulcer deaths showed a significant increase (OR, 1.60; 95% CI, 1.06-2.41) in the PPI therapy group. Sensitivity analysis of 22 trials published in peer-reviewed journals, 10 trials with double-blind design and 19 trials with high quality score and 22 trials using omeprazole in the treatment group showed results similar to those seen in the analysis of all 26 trials, confirming the stability of the conclusions. Subgroup analysis revealed that summary outcome measures were not influenced by control group therapy (placebo vs H2 receptor antagonists) or the use of prior endoscopic treatment to achieve hemostasis (given vs not given). However, the summary treatment effects for further bleeding and need for surgery were significant in only those trials enrolling patients with peptic ulcers having high risk for rebleeding and not in those trials enrolling patients with all causes of UGI bleeding. The summary treatment effects for further bleeding and need for surgery were significant in trials using intravenous as well as oral PPI. However, summary OR for all-cause deaths and non-ulcer deaths in trials using intravenous PPI were higher in the treatment group and not in trials using oral PPI. This raised the possibility of intravenous PPI-therapy-associated non-ulcer deaths in high-risk patients. PPI therapy in acute non-variceal UGI bleeding reduced rates of further bleeding, surgery and deaths caused by ulcer complications. However, non-ulcer deaths were increased. The overall mortality was unaffected. PPI therapy is useful only in a selected group of patients with acute non-variceal UGI bleeding, namely those with peptic ulcers having endoscopic high-risk stigmata for rebleeding.

Taking account of vaginal bleeding in screening for Down's syndrome.

OBJECTIVE: To derive a method for revising the risk of Down's syndrome in maternal serum marker screening when there is vaginal bleeding. The effect on screening performance of routinely allowing for the presence or absence of bleeding in all women is also assessed. DESIGN: Overview of published studies on the rate of reported vaginal bleeding in pregnancies with Down's syndrome, on the rate according to maternal age and on the association of bleeding with alpha-fetoprotein (AFP) level. The publications are supplemented with data on unconjugated oestriol (uE3), human chorionic gonadotrophin (hCG) and AFP levels in a consecutive series of screened women. SETTING: Routine Down's syndrome screening tests carried out on women having antenatal care at the St James's University Hospital, Leeds. SUBJECTS: Eight hundred and nine screened women. RESULTS: In five studies the rate of vaginal bleeding in Down's syndrome pregnancies was 1.7 times that in unaffected pregnancies on average. In three studies, the vaginal bleeding rate increased proportionally by 2.2% on average for each year of maternal age. Three studies and our own data were consistent with a 10% increase in the mean AFP level associated with vaginal bleeding, but it did not appear to materially alter uE3 and hCG levels or the standard deviations and correlation coefficients for any of the three analytes. An individual woman's risk was calculated by multiplying her age-specific odds of Down's syndrome by two likelihood ratios, one relating to the vaginal bleeding itself and one from the marker levels. Routine allowance for the presence or absence of vaginal bleeding was estimated to increase the detection rate by less than 1%. CONCLUSION: Our method is of clinical value in revising the risk when there is concern that vaginal bleeding might be responsible for a negative maternal serum Down's syndrome screening result. A policy of routinely incorporating information on vaginal bleeding in risk estimation for all women would have too small an effect on overall screening performance to recommend it.

The frequency of significant pathology in women attending a general gynaecological service for postcoital bleeding.

OBJECTIVES: To document the frequency of pathology in women who complain of postcoital bleeding. To determine whether negative cervical cytology excludes serious pathology in women with postcoital bleeding. To determine whether postcoital bleeding increases the risk of serious pathology in women with an abnormal smear. DESIGN: A retrospective study. SETTING: A university teaching hospital. POPULATION: 314 women with postcoital bleeding seen in the gynaecology service from first January 1988 to 31 December 1994. METHODS: Women were identified from the computerised records of the colposcopy service and copies of correspondence, which was routinely retained on computer. The latter was searched for the text strings coital and intercourse. MAIN OUTCOME MEASURE: Histopathological diagnosis. RESULTS: Twelve women (4%) had invasive cancer: 10 were cervical or vaginal cancers and two endometrial cancers. Eight of the 10 cervical or vaginal cancers were clinically apparent. Four women of these 10 had had a normal smear before being referred for further investigation of postcoital bleeding. Two of these cancers were visible only with the aid of the colposcope. Thus, 0.6% of women attending a gynaecology service with postcoital bleeding, a normal looking cervix and a normal smear had invasive cancer of the cervix. Cervical intraepithelial neoplasia were found in 54 women (17.%) and 15 women (5%) had cervical polyps. Nineteen of the 63 women (30%) with significant pathology had a normal or inflammatory cervical smear. No explanation for the postcoital bleeding was found in 155 women (49 %). CONCLUSIONS: Although invasive cancer is rare in women with postcoital bleeding, it is much commoner than in the general population. It seems likely that cervical intraepithelial neoplasia is also associated with postcoital bleeding, perhaps because the fragile cervical epithelium becomes detached during intercourse. Postcoital bleeding should continue to be regarded as an indication of high risk for invasive cervical cancer and for cervical intraepithelial neoplasia. Prompt referral to a colposcopy clinic is indicated, but most women with postcoital bleeding will have no serious abnormality.

Bleeding disorders in teenagers presenting with menorrhagia.

OBJECTIVE: To assess the prevalence of bleeding disorders and establish the clinical variables that are predictive of a bleeding disorder in adolescent women. DESIGN: A retrospective audit of all patients who had coagulation tests following presentation with menorrhagia. SETTING: Inpatient and outpatients of a tertiary adolescent gynaecology service. PATIENTS: Subjects aged 9-19 years with menorrhagia who had coagulation tests performed, and who did not have a known bleeding disorder prior to presentation were included. OUTCOME MEASURES: A bleeding screen was performed to assess prevalence of bleeding disorders in the population. Variables that were investigated as predictive of a bleeding disorder included clinical history, family history, and haematological indices of blood loss. RESULTS: The prevalence of an inherited bleeding disorder was 10.4%. The only statistically significant predictor was a family history of bruising and bleeding. Menstrual history was not predictive. CONCLUSION: Severity of menstrual loss was not predictive of a bleeding disorder, as a significant cause of teenage metrostaxis is due to anovulatory dysfunctional uterine bleeding. The authors recommend that a careful personal and family history of bruising and bleeding be taken in all teenagers who present de novo with menorrhagia. Routine screening in a primary care setting is impractical, but should be mandatory in all patients with a positive family history.

Bleeding reflux esophagitis: a prospective 1-year study in a university hospital.

OBJECTIVES: The prevalence of bleeding from reflux esophagitis has not been studied. The aim of the study was to evaluate the 1-yr prevalence of bleeding from reflux esophagitis, as well as the independent factors associated with bleeding. METHODS: All patients with reflux esophagitis diagnosed with upper digestive tract endoscopy in Reims Hospital in 1996 were included. Studied parameters were prospectively recorded and compared between patients with bleeding and nonbleeding reflux esophagitis. RESULTS: Endoscopy was performed in 1983 patients of whom 219 (11.0%) had overt upper digestive tract hemorrhage. Reflux esophagitis was the cause of bleeding in 32 patients (14.6%). Reflux esophagitis was diagnosed in 391 patients during the same period of time. Bleeding reflux esophagitis accounted for 8.2% of them. Independent factors associated with bleeding were grade 3 or 4 (Savary-Miller) esophagitis (odds ratio [OR]: 25.5, 95% confidence interval [CI]: 9.6-67.9), cirrhosis (OR: 5.7, 95% CI: 1.7-18.9), Eastern Cooperative Oncology Group performance status > or = 3 (OR: 4.6, 95% CI: 1.5-14.2), and anticoagulant therapy (OR: 3.9, 95% CI: 1.2-12.5). A history of reflux esophagitis or heartburn was noted in only 28.1% or 37.5% of the patients with bleeding reflux esophagitis, respectively. CONCLUSIONS: In this population of patients with reflux esophagitis, the prevalence of bleeding esophagitis was high (8.2%). Bleeding esophagitis occurred primarily in patients with severe esophagitis and was the revealing clinical form of gastroesophageal reflux disease in the majority of cases, suggesting that bleeding prevention would hardly be effective.

The utility of urgent colonoscopy in the evaluation of acute lower gastrointestinal tract bleeding: a 2-year experience from a single center.

OBJECTIVE: Urgent colonoscopy is often recommended to evaluate acute rectal bleeding. However, it may not identify a source because of blood in the lumen or inadequate preparation. Our aim was to determine the utility of urgent colonoscopy as the initial test for acute rectal bleeding. METHODS: This was a retrospective chart review of all patients discharged in 1997 and 1998 with an International Classification of Diseases, 9th Revision, code for hematochezia or rectal bleeding. RESULTS: We identified 514 charts but excluded 424 because of inaccurate coding. In the 90 with confirmed acute rectal bleeding, colonoscopy was the initial test in 39; age, sex, and race distributions were similar to those who did not have colonoscopy. A definite source of bleeding was seen at colonoscopy in only three patients, a probable source in 26, and no source in 10. Therapeutic intervention in four patients with a definite or probable source was successful in three. The commonest reasons for not performing urgent colonoscopy were bleeding from presumed hemorrhoids or bleeding that was clinically insignificant. Spontaneous resolution of bleeding and length of hospital stay were not affected by urgent colonoscopy. Five patients had surgery for unrelated reasons. In-hospital mortality was 2% and was unrelated to bleeding. CONCLUSION: Urgent colonoscopy as the initial investigation in acute lower GI tract bleeding probably does not alter the outcome in most cases. Identification of a definite bleeding source leading to successful therapeutic intervention is rare. Spontaneous resolution is frequent, length of hospital stay is similar, and clinical outcome is excellent regardless of whether or not urgent colonoscopy is performed.

An assessment of the management of acute bleeding varices: a multicenter prospective member-based study.

OBJECTIVE: Bleeding from esophagogastric varices is a major complication of portal hypertension. Despite recent practice guidelines for the management of bleeding esophageal or gastric varices, the widespread application of these measures by gastroenterologists has not been evaluated. The purpose of this study was to continue the concept of membership-based research within diverse practice settings by expanding the American College of Gastroenterology (ACG) GI Bleeding Registry to assess the management and outcome of acute variceal bleeding. METHODS: All ACG members (domestic and foreign) were invited to participate during the 1997 Annual Fall meeting and by mail. Data were collected over 12 months. Information obtained included physician training, practice demographics, patient demographics, disease etiology and severity, clinical presentation, medications, transfusion needs, therapy, complications, and rebleeding within 2 wk. RESULTS: A total of 93 physicians/centers (79.6% domestic, 26.9% university and affiliated, 3.2% Veterans Affairs) participated. Complete demographic data were available for 725 of the 741 patients enrolled with index bleeding. The median age of these 725 patients was 52 yr and 73.3% were male. The most common single etiology for portal hypertension was cirrhosis (94.3%). The most common causes of cirrhosis were alcohol (56.7%), hepatitis C virus (30.3%), and hepatitis B virus (10.0%). Hemodynamic instability was noted in 60.7% of the patients (22.3% tachycardic, 9.7% orthostatic, 28.7% hypotensive). Index interventions included banding (40.8%; median five bands), sclerotherapy (36.3%), combination banding/sclerotherapy (6.2%), octreotide (52.6%; median 3 days), balloon tamponade (5.5%), transjugular intrahepatic portosystemic shunt (TIPS) (6.6%), liver transplantation (1.1%), surgical shunt (0.7%), and embolization (0.1%). Transfusion of packed red blood cells, fresh frozen plasma, and platelets was given in 83.4%, 44.7%, and 24.6% of the patients with index bleeding, respectively. Median transfusion was four units of packed red blood cells, three units of fresh frozen plasma, and 1.5 units of platelets. Rebleeding occurred in 92 of the 741 patients (12.6%) at a median of 7 days (mean 11 days) and was treated by banding (18.5%; median six bands), sclerotherapy (30.4%), octreotide (63%; median 2 days), balloon tamponade (17.4%), TIPS (15.2%), and surgical shunt (3.3%). Complications from the index bleeding and rebleeding within 2 wk included ulceration (2.6%, 2.2%), aspiration (2.4%, 3.3%), medication side effects (0.8%, 0%), dysphagia (2.3%, 0%), odynophagia (2.2%,0%), encephalopathy (13%,17.4%), and hepatorenal syndrome (2.4%, 2.2%), respectively. After the index bleeding, 46.2% of patients were treated with beta-blockers and 8.2% with nitrates. The majority of patients with index bleeding had Child's B cirrhosis (61.5%). Patients presenting with recurrent bleeding had mostly Child's B (46.7%) or Child's C cirrhosis (44.6%). The overall short-term mortality after index bleeding was 12.9%. CONCLUSIONS: Acute variceal hemorrhage occurs more often in patients with Child's B and C cirrhosis. Endoscopic banding is the most common single endoscopic intervention. Adjunctive pharmacotherapy is prevalent acutely and after stabilization. Both morbidity and mortality may be lower than reported in previous studies.

Bleeding complications after percutaneous liver biopsy. An analysis of risk factors.

BACKGROUND AND AIMS: To assess the risk of bleeding after percutaneous liver biopsy, we retrospectively analyzed 629 procedures with particular respect to patients with an increased a priori bleeding risk. METHODS: Factors possibly related to the risk of bleeding were analyzed by univariate analysis. Those variables which were significant in the univariate analysis were then entered into a forward conditional logistic regression model. RESULTS: Biopsy-related bleeding events defined as clinically overt complication (n = 10; 1.6%), an otherwise unexplained drop in serum hemoglobin concentration of greater than 2 g/dl (n = 45; 7.1%) or intra- or extrahepatic hematoma assessed by ultrasound (n = 17; 2.7%) were identified in 72 patients. 58% of the bleeding events occurred in patients with particular risk factors for bleeding. Biopsy-related mortality in the study cohort was 0.48%. Logistic regression analysis indicated mycobacterial infection [odds ratio (OR) 24.0], pre-biopsy prophylactic platelet substitution (OR 9.9), acute liver failure (OR 9.1), heparin administration on the day of biopsy (OR 8.7), advanced liver cirrhosis (OR 5.1), therapy with corticosteroids (OR 3.5) or metamizole (OR 2.8) and leukemia or lymphoma (OR 2.8) as significant (p < or = 0.05) independent risk factors. Delayed bleeding (>24 h after biopsy) was identified in 70% of the bleeding events. CONCLUSIONS: In our study cohort which comprised a high proportion of patients with particular risk factors for bleeding, biopsy-related bleeding occurred more frequently and later than commonly observed and was associated with only a few prognostic factors. Considering these predictors before liver biopsy will aid to reduce the rate of bleeding complications.

Bleeding complications with the chimeric antibody to platelet glycoprotein IIb/IIIa integrin in patients undergoing percutaneous coronary intervention. EPIC Investigators.

BACKGROUND: The potential for novel antiplatelet and antithrombin agents to contribute to periprocedural bleeding complications of percutaneous coronary revascularization is poorly defined. In the Evaluation of c7E3 Fab in Preventing Ischemic Complications of High-Risk Angioplasty (EPIC) trial, the periprocedural use of aspirin, heparin, and a chimeric antibody to the platelet glycoprotein IIb/IIIa integrin c7E3 Fab in 2099 patients significantly reduced postprocedural ischemic complications and 6-month clinical restenosis but was associated with increased procedural bleeding complications. We review these complications and describe clinical and procedural variables associated with increased bleeding complications in the EPIC trial. METHODS AND RESULTS: Patients with high-risk clinical or lesion morphological characteristics were randomized to receive placebo bolus plus placebo infusion, c7E3 Fab bolus plus placebo infusion, or c7E3 Fab bolus plus c7E3 Fab infusion. Patients received periprocedural aspirin and intravenous heparin continued for a minimum of 12 hours after the procedure. Outcomes reflecting bleeding complications were measured: transfusions, decreased hemoglobin, and an index including both parameters. Major bleeding complications unrelated to bypass surgery occurred in 3.3%, 8.6%, and 10.6%, and blood product transfusions were used in 7.5%, 14.0%, and 16.8% of patients treated with placebo, bolus c7E3 Fab, and bolus plus infusion c7E3 Fab, respectively (both P < .001). Most major bleeding complications occurred at the femoral access site, regardless of treatment. Intracranial hemorrhage (0.3%) and death (0.09%) attributable to major bleeding complications were rare. Multivariable regression analyses identified several variables significantly and independently related to major bleeding complications or greater blood loss, including greater age, female sex, lower weight, c7E3 Fab therapy, and duration and complexity of the index procedure. Major bleeding complications and blood loss in patients receiving bolus plus infusion were not significantly greater than in those receiving bolus alone (P = .38 and P = .14, respectively). CONCLUSIONS: Bleeding complications unrelated to bypass surgery were two to three times more frequent in patients receiving c7E3 Fab than in those receiving placebo, but most were transient and well tolerated. Risk-factor analysis and modification of concomitant antithrombotic and antiplatelet treatment strategies may aid in reducing bleeding complications and enhancing clinical benefit in patients receiving c7E3 Fab during percutaneous coronary revascularization.

Sex differences in major bleeding with glycoprotein IIb/IIIa inhibitors: results from the CRUSADE (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA guidelines) initiative.

BACKGROUND: Glycoprotein (GP) IIb/IIIa inhibitors are beneficial in patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS); their safe use in women, however, remains a concern. The contribution of dosing to the observed sex-related differences in bleeding is unknown. METHODS AND RESULTS: We explored the relationship between patient sex, GP IIb/IIIa inhibitor use, dose, and bleeding in 32 601 patients with NSTE ACS across 400 CRUSADE (Can Rapid risk stratification of Unstable angina patients Suppress ADverse outcomes with Early implementation of the ACC/AHA guidelines) hospitals, of whom 18 436 were treated. GP IIb/IIIa inhibitor dose was defined as excessive if not reduced when creatinine clearance was < 50 mL/min for eptifibatide or < 30 mL/min for tirofiban. Major bleeding was defined as a hematocrit drop > or = 0.12, need for transfusion, or intracranial bleeding. Major bleeding was adjusted for clinical factors and antithrombotic dose. The risk for bleeding attributable to excess GP IIb/IIIa dose was determined by sex using prevalence and adjusted odds ratios (ORs). Women had higher rates of major bleeding than men among those treated with GP IIb/IIIa inhibitors (15.7% versus 7.3%, P<0.0001) and among those not treated (8.5% versus 5.4%, P<0.0001). Despite similar serum creatinine levels, creatinine clearance averaged 20 points lower among treated women than men. Treated women were also more likely to receive excess GP IIb/IIIa doses than men (46.4% versus 17.2%, P<0.0001; adjusted OR 3.81, 95% confidence interval [CI] 3.39 to 4.27). Excess dosing was associated with increased risk of bleeding in women (OR 1.72, 95% CI 1.30 to 2.28) and men (OR 1.27, 95% CI 0.97 to 1.66); however, bleeding risk attributable to dosing was much higher in women (25.0% versus 4.4%). CONCLUSIONS: Women experience more bleeding than men whether or not they are treated with GP IIb/IIIa inhibitors; however, because of frequent excessive dosing in women, up to one fourth of this sex-related risk difference in bleeding is avoidable. Appropriate dosing will improve care of all patients with NSTE ACS, with a particular benefit for women.
