[Utility of bolus somatostatin administration in preventing pancreatitis after endoscopic retrograde cholangiopancreatography: a controlled, non-randomized study].

INTRODUCTION: Somatostatin is one of the most extensively evaluated drugs in the prophylaxis of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP), but its utility remains controversial. PATIENTS AND METHODS: The aim of this study was to evaluate the role of somatostatin as prophylaxis of ERCP-induced acute pancreatitis. A group of consecutive patients that underwent ERCP in our endoscopy unit was prospectively studied for 8 months. Patients in this group were administered an endovenous bolus of 250 micrograms of somatostatin immediately before introducing the catheter in the papilla of Vater (somatostatin group). This group was compared with another group composed of consecutive patients who had undergone ERCP in the 8 previous months, without somatostatin administration (placebo group). Both groups contained the same number of patients. The following variables were recorded; sex, age, contrast injection in the duct of Wirsung, endoscopist, therapeutic maneuvers, and the development of post-ERCP pancreatitis. RESULTS: During the 16 months of patient inclusion, we performed 320 ERCP in our unit, of which 248 were included in the study: 142 in the somatostatin group and 142 in the placebo group. Of these patients, 152 (53.5%) were men and 132 (46.5%) were women. The mean age was 70.05 +/- 13.83 years (range: 27-93 years). Acute pancreatitis occurred in 10 patients in the somatostatin group and in 5 in the placebo group; this difference was not statistically significant (p > 0.05). No significant differences were found between the two groups in the remaining variables studied. CONCLUSION: Somatostatin does not seem to be useful in preventing post-ERCP acute pancreatitis.

Informed consent document in gastrointestinal endoscopy: understanding and acceptance by patients.

OBJECTIVE: We wanted to know if patients read and understand the informed consent (IC) document used for endoscopic procedures, and to evaluate the readability of IC. METHOD: During two months we gave patients studied in our endoscopy unit an anonymous questionnaire with different items concerning reading degree, knowledge of the technique, complications, sedation used, and information received. We evaluated IC readability using the Flesch index. RESULTS: 309 patients were included (mean age: 53 years, 55% males, 86% outpatients, 50% with basic education); 85% of patients read the IC, 96% considered they understood the exploration technique, 22% were not aware of severe complications, and 82% knew which kind of sedation would be used; 88% of patients received additional information from their doctors. Outpatients read the IC in a greater percentage versus inpatients (p < 0.05); patients with only basic education tended to ignore the possibility of complications (p < 0.05). Doctors gave more information to rural patients (p = 0.08), offered better information about complications to urban patients (p = 0.09), and offered more information on other diagnostic procedures to patients older than 50 years (p < 0.05). With the Flesch index we found that gastroscopy and colonoscopy ICs had a "standard" level of readability, while ERCP ICs were more complex. CONCLUSIONS: The majority of our patients read and understands the IC. Doctors adapt information to patient characteristics. Our IC documents have an acceptable level of readability, but given that 50% of our patients have only a basic educational status, we should attempt to provide an easier IC document.

Changes in body weight and health-related quality-of-life in the older adult population.

BACKGROUND: No other study has ascertained the short-term impact of weight change on health-related quality-of-life (HRQL) on a national sample of older adults. OBJECTIVE: To examine the relationship between change in body weight and HRQL among the older adult population. METHODS: We carried out a prospective study from 2001 to 2003 of a cohort of 2364 persons, representative of the noninstitutionalized Spanish population aged 60 y and over. Weight changes during the period 2001-2003 were self-reported, and HRQL in 2003 was measured with the SF-36 questionnaire. Analyses adjusted for the principal confounders. RESULTS: Among nonobese women (body mass index (BMI) 18.5-29.9 kg/m(2)), and compared to those who underwent no important weight change, weight loss was associated with a clinically significant worsening in the role-physical, vitality, and social functioning SF-36 scales. Among obese women (BMI> or =30 kg/m(2)), weight gain led to a reduction in HRQL for four of the eight SF-36 scales, while weight loss was associated with worse scores in role-emotional and mental health scales. Results were usually similar for men, though of lower magnitude. In both sexes, weight change was associated with a reduction of over 5 points on several physical and mental scales of the SF-36, which indicates a clinically relevant worsening in HRQL. CONCLUSION: Weight change is associated with worse HRQL among the older adults, principally women. From the stance of HRQL, it is desirable to prevent weight gain, especially among the obese, and weight loss, especially among the nonobese.

Burden of illness of Crohn's disease in Spain.

OBJECTIVE: To evaluate the burden of Crohn's disease in Spain. DESIGN: Observational, cross-sectional study of patients affected with Crohn's disease who were attended to in hospitals in Spain. METHODS: Three structured questionnaires were used: one completed by the gastroenterologists to obtain demographic, clinical and disease activity data; a phone interview to obtain epidemiological and drug utilisation data; and the Spanish version of the Short-Form Health Survey (SF-36). RESULTS: The annual cost per patient was estimated at Euro 6808-Euro 2104 from direct medical costs and Euro 4704 from indirect costs. Approximate effect sizes for health-related quality of life were as follows: 0.8 for general health, social function, role functioning--physical and vitality; 0.5 for role functioning--emotional, body pain and mental health; and 0.2 for physical function. CONCLUSION: Crohn's disease causes a significant decrease in health-related quality of life for patients and a considerable economic cost to society, mainly due to hospitalisations and loss of productivity. This burden indicates the importance of health programmes and interventions in reducing the heavy impact of the disease on both patients and society.

[Upper digestive haemorrhage due to Mallory-Weiss syndrome. Role of endoscopic sclerotherapy].

BACKGROUND: Although Mallory-Weiss syndrome is responsible for between 0.5 and 17% of the cases of upper digestive haemorrhage, the information existing on the endoscopic treatment of this syndrome is scarce. MATERIAL AND METHODS: We made a retrospective study of 71 patients with haemorrhage due to Mallory-Weiss syndrome, dividing them into two groups according to the treatment they had received (medical or medical-endoscopic). Hence, 60 patients (30 with clean laceration, 9 with signs of prior haemostasia and 21 with fresh clotting) had been treated with procinetics and/or antisecretories alone, while the 11 remaining (8 with active haemorrhage, 2 with visible vessel and 1 with fresh clotting) had also received endoscopic treatment with sclerotherapy. We compared the clinical and analytical characteristics and the evolution of both groups of patients, analysing the data by means of the Mann-Whitney U and the chi 2 test. RESULTS: The endoscopic sclerosis group showed maelenas more frequently and more severe analytical data of haemorrhage (p<0.01). Endoscopic sclerosis brought initial control of the haemorrhage in all the patients, with a low index of haemorrhage relapse, similar to the group receiving exclusively medical treatment. CONCLUSIONS: In our series, the patients with Mallory-Weiss syndrome with active bleeding or visible vessel presented a haemorrhage with a greater clinical and analytical repercussion. In this group of patients, endoscopic sclerotherapy controlled the haemorrhage and/or prevented rebleeding, in the absence of complications.

Screening, monitoring, and educating patients with diabetes in an independent community pharmacy in Puerto Rico.

OBJECTIVE: Increase the awareness about the importance of Diabetes mellitus (DM) management and assess the educational and monitoring needs of patients visiting a community pharmacy in Puerto Rico. METHODS: A community service activity focusing on DM was held in a community pharmacy. The educational and monitoring needs of the participants were assessed using a questionnaire. Glucose tests were conducted in the pharmacy by medical technologists. Educational activities consisted of presentations and printed materials. RESULTS: Two-thirds of the fasting people had blood glucose levels higher than 140 mg/dl. Seventy-nine percent of the patients with diabetes were not aware of the glycosilated hemoglobin test. Most of the patients were interested in learning more about how to manage their condition. CONCLUSION: A greater understanding is needed among patients with DM that blood glucose control decreases diabetes related complications. Community pharmacists are in an excellent position to collaborate with other health professionals in screening, monitoring and educating patients with DM to prevent long-term complications.

Relationship of plasma bone cytokines with hypercalcemia in cancer patients.

The pathogenesis of cancer-associated hypercalcemia is not yet completely understood. This syndrome appears to be a consequence of the tumor production of humoral factors, mainly parathyroid hormone related protein (PTHrP). However, patients with humoral hypercalcemia of malignancy have features suggesting that factors other than PTHrP might play a role in this syndrome. We performed a case-control study in cancer patients with and without hypercalcemia. A total of 105 patients with a variety of tumors, 60 of them with hypercalcemia (corrected serum calcium over 2.6 mmol/l), and 45 without hypercalcemia. In a previous study, we demonstrated that plasma PTHrP was highly associated with hypercalcemia in these patients. In the present study, we measured the plasma levels of various bone cytokines: interleukin-1beta (IL-1beta), interleukin-6 (IL-6), transforming growth factor (TGF) alpha, and tumor necrosis factor (TNF) alpha, in these cancer patients. We also determined C-terminal type I procollagen (PICP) and C-terminal telopeptide of type I collagen (ICTP), bone formation and bone resorption markers, respectively, in serum in these patients. We found that these osteolytic cytokines do not increase in plasma by the presence of hypercalcemia. In fact, using a logistic regression analysis, a significant (P<0.02) association was found between the low plasma levels of IL-1beta and TGFalpha and hypercalcemia, independent of plasma PTHrP and the presence of bone metastasis, in these patients. No significant association between the plasma levels of IL-6 or TNFalpha and hypercalcemia was found in these cancer patients. Serum ICTP correlated (r=0.35; P=0.008) with hypercalcemia in these patients, but none of the cytokines studied in plasma correlated with either ICTP or PICP in these hypercalcemic patients. Our data indicate that the circulating levels of several bone cytokines are not enhanced by PTHrP in hypercalcemic cancer patients. The mechanism responsible for the association between the low plasma levels of some of these cytokines and hypercalcemia in these patients remains obscure. However, this finding does not rule out the possible local bone effects of these cytokines, contributing to hypercalcemia in cancer patients.

Clinical and histological outcome after hepatitis B e antigen to antibody seroconversion in children with chronic hepatitis B.

Data regarding the outcome of children with chronic hepatitis B after seroconversion are scarce. We describe the long-term evolution of these patients. One hundred and three children with antibody against hepatitis B e antigen and normal alanine aminotransferase (ALT) levels were followed for 0.6 to 12.5 years (mean, 6.3 years). Paired liver biopsies (before and after seroconversion) were available in 83 cases. Final biopsies were obtained 0.5 to 12.5 years (mean, 4.5 years) after seroconversion. ALT levels remained normal in most of the children (79%) throughout the follow-up. All children, except five who lost hepatitis B surface antigen, had serum viral DNA detected by polymerase chain reaction. When comparing baseline and final liver biopsies, a significant improvement (P <.001) was found in the histological activity index and in the necrosis, cytolysis, inflammation, and fibrosis scores. The histological diagnosis improvement in the final biopsy was significantly related (P <.001) to the time from seroconversion to the biopsy performance. All children had viral DNA on their final liver biopsy. In summary, seroconversion and ALT normalization are quite stable findings in children, and no differences in the long-term outcome between treated and untreated children were found. In light of the histological outcome, it seems unnecessary to perform a follow-up liver biopsy in these cases.

Retreatment of chronic hepatitis B e antigen-positive patients with recombinant interferon alfa-2a. The European Concerted Action on Viral Hepatitis (EUROHEP).

Fifty-seven patients with chronic hepatitis B, hepatitis B virus (HBV) e antigen (HBeAg) and HBV DNA positivity, and aminotransferase elevation despite a previous course of any type of adequate interferon alfa (IFN-alpha) therapy were included in a multicenter prospective randomized controlled trial. The objective of the study was to compare a second course of IFN-alpha therapy (9 million units [MU] of IFN-alpha-2a, Roferon-A, thrice weekly for 6 months) versus no therapy in terms of loss of HBV DNA and HBeAg. At the end of the study, a sustained clearance of HBV DNA and HBeAg was observed in 9 of the 27 (33.3%) patients who had received retreatment with IFN-alpha compared with 3/30 (10%) patients who spontaneously cleared these markers in the untreated control group (chi2 = 4.66, P =.031; odds ratio: 4.5, 95%; confidence interval: 1.1-18.9). None of the responders lost HBsAg. Patients retreated with IFN-alpha were more likely to have biochemical remission in association with HBV clearance (5/27, 18.5%) compared with untreated patients (1/30, 3. 3%; Fisher's exact test P =.09 ). Histological improvement in the liver necroinflammatory activity was observed among sustained responders to IFN-alpha retreatment, consisting of regression of the portal and periportal inflammation and of the piecemeal necrosis; there was no change in the degree of liver fibrosis. Side effects were similar to those previously reported during IFN-alpha treatment; these were mild and reversible on IFN-alpha discontinuation. None of the baseline features were associated with response by Cox's regression analysis. In summary, viremic patients with chronic HBeAg-positive hepatitis may experience disease remission following retreatment with IFN-alpha. Thus, retreatment with IFN-alpha may be considered a therapeutic option.

Omega-3 fatty acids in adipose tissue and risk of myocardial infarction: the EURAMIC study.

Omega-3 fatty acids have potential antiatherogenic, antithrombotic, and antiarrhythmic properties, but their role in coronary heart disease remains controversial. To evaluate the association of omega-3 fatty acids in adipose tissue with the risk of myocardial infarction in men, a case-control study was conducted in eight European countries and Israel. Cases (n=639) included patients with a first myocardial infarction admitted to coronary care units within 24 hours from the onset of symptoms. Controls (n=700) were selected to represent the populations originating the cases. Adipose tissue levels of fatty acids were determined by capillary gas chromatography. The mean (+/-SD) proportion of alpha-linolenic acid was 0.77% (+/-0.19) of fatty acids in cases and 0.80% (+/-0.19) of fatty acids in controls (P=0.01). The relative risk for the highest quintile of alpha-linolenic acid compared with the lowest was 0.42 (95% confidence interval [CI] 0.22 to 0.81, P-trend=0.02). After adjusting for classical risk factors, the relative risk for the highest quintile was 0.68 (95% CI 0.31 to 1.49, P-trend=0.38). The mean proportion of docosahexaenoic acid was 0.24% (+/-0.13) of fatty acids in cases and 0.25% (+/-0.13) of fatty acids in controls (P=0. 14), with no evidence of association with risk of myocardial infarction. In this large case-control study we could not detect a protective effect of docosahexaenoic acid on the risk of myocardial infarction. The protective effect of alpha-linolenic acid was attenuated after adjusting for classical risk factors (mainly smoking), but it deserves further research.

Cost-benefit analysis of Haemophilus influenzae type b vaccination in children in Spain.

OBJECTIVE: Invasive disease caused by Haemophilus influenzae type b (Hib), including meningitis, pneumonia, sepsis and epiglottitis, is associated with high mortality and serious neurological sequelae in children under 5 years of age. The availability of an efficacious vaccine suggests the need to perform an economic evaluation of its use. The objective of this study was to evaluate the costs and benefits of introducing a universal vaccination programme for children under 1 year of age in Spain. DESIGN & SETTING: A cost-benefit analysis (CBA) was conducted over a 5-year period from the societal perspective in the Spanish healthcare setting. Both direct and indirect costs were included in the analysis [using 1996 Spanish pesetas (Pta); Pta126.5 = $US1 in April 1996]. PATIENTS AND PARTICIPANTS: The target population used for cost and benefit estimation was the 384,883 Spaniards aged 1 year or less in the last Spanish Population and Housing Census of 1991. MAIN OUTCOME MEASURES AND RESULTS: The introduction of the universal Hib vaccination programme would imply vaccinating 346,395 children under 1 year of age, with a global expense of Pta2,444,855,910. For an average incidence of 15 cases of invasive disease per 100,000 children per year nationwide, the programme would prevent 219 cases of invasive disease and 8 deaths over a 5-year period, with a benefit of Pta2,182,868,907, a net benefit (i.e. benefit minus cost) of -Pta261,987,003, a benefit/cost ratio of 0.89 and a benefit per case prevented of -Pta1,196,288. Benefit/cost ratios above 1 would be obtained in the regions of highest incidence of invasive disease. CONCLUSION: The decision to implement a universal vaccination programme should not be based only on economic factors, but our results suggest that the economic returns of the programme for children under 1 year of age in Spain would be at least of a similar magnitude as its expenses.

Severity of cognitive impairment in juvenile and late-onset Huntington disease.

OBJECTIVES: To compare the severity of cognitive impairment among groups of patients with different age ranges at the onset of Huntington disease (HD) and to evaluate the variable influence of motor and cognitive deficits on functional disability across different ages at the onset of HD. DESIGN: Cross-sectional multidisciplinary evaluation of patients referred to our institution for care related to a possible diagnosis of HD. SETTING: The Huntington disease program in the Departments of Neurology and Genetics at the Fundación Jimenez Diaz, Madrid, Spain. PARTICIPANTS: Seventy-one patients with Huntington disease were classified into 3 groups depending on age at onset of motor symptoms: juvenile onset, 25 years of age or younger (group 1, n = 15); adult onset, from 26 to 50 years (group 2, n = 43); and late onset, 51 years or older (group 3, n = 13). Age- and education-matched controls (n=50) were included to compare cognitive performance with patients in groups 1 and 3. MEASURES: Cognitive evaluation encompassed a wide neuropsychological battery to assess global cognitive functioning and visuospatial, prefrontal, and memory functions. Clinical data included motor and functional variables measured by using the Unified Huntington's Disease Rating Scale. Genetic analysis determined the number of CAG trinucleotide repeats. RESULTS: Patients in group 1 scored 2.9 points and patients in group 3 scored 4.2 points below their respective controls on the Mini-Mental State Examination. Patients in groups 1 and 3 were similarly impaired in verbal memory. Visual function was much more impaired in patients in group 3, and prefrontal functions were slightly worse in patients in group 1. Cognitive scores were correlated only with time of evolution for patients in group 2. Functional scores were not significantly different among the 3 groups, but 11 (85%) of the patients in group 3 were in stage I or II vs 10 (67%) of the patients in group 1. Total functional capacity correlated better with the Mini-Mental State Examination score for patients in group 3 and with motor deficits (akinesia) and prefrontal dysfunction for patients in group 1. The mean+/-SD CAG repeat length decreased from 59.9+/-12.6 for patients in group 1 to 46.2+/-3.5 for patients in group 2 and 41.7+/-2.6 for patients in group 3. Longer CAG repeats in the HD study population correlated with akinetic features but not with cognitive performance. CONCLUSIONS: Despite the much greater genetic defect, cognitive status is slightly better preserved in patients with juvenile-onset HD. Cognitive impairment in patients with juvenile- and late-onset HD differs in the severity of visual and prefrontal deficits. Functional disability in patients with late-onset HD depends more on global cognitive status, while in patients with juvenile-onset HD, it is conditioned more by motor deficits and prefrontal dysfunction.

Comparison of two immunoradiometric assays for parathyroid hormone-related protein in the evaluation of cancer patients with and without hypercalcemia.

Hypercalcemia is a common paraneoplastic syndrome due to the secretion by tumors of parathyroid hormone-related protein (PTHrP) and/or other osteolytic factors. In the present study, we have measured plasma PTHrP using two immunoradiometric assays for PTHrP, assay N (Nichols) and assay I (INCSTAR), recognizing the 1-86 domain of PTHrP, for the evaluation of malignancy-associated hypercalcemia. The study included 25 tumor patients with hypercalcemia (HCa) [corrected serum calcium (SCa) > or = 2.70 mmol/L], 20 normocalcemic patients with cancer (NCa), and ten healthy control subjects. Plasma PTHrP was either undetectable or within the respective normal range in the majority of NCa patients and in the control subjects, with both assays. Plasma PTHrP was increased in 13 and 15 of HCa cases with assay N and assay I, respectively. PTHrP was elevated in plasma in 5/6 (assay N) and 3/6 (assay I) HCa patients with squamous tumors. However, plasma PTHrP was high in only 2/9 (assay N) and 1/9 (assay I) HCa cases with hematological tumors. Less than 40% of HCa patients with bone metastases, and >75% of those without bone involvement, had elevated plasma PTHrP with both assays. Detectable plasma PTHrP and SCa were significantly correlated using assay N (p = 0.025) and assay I (p = 0.01), in the HCa group. A highly significant correlation (p <0.001) was found between detectable plasma PTHrP with both assays, and a high agreement between them based on simple kappa statistics (p < 0.001), in the latter group. Our results indicate that each assay may be similarly useful in detecting PTHrP hyperproduction in cancer patients.

Parenteral administration of different amounts of branch-chain amino acids in septic patients: clinical and metabolic aspects.

OBJECTIVE: To study the effects of a total parenteral nutrition solution changing branch-chain amino acid concentrations and/or nitrogen supply on protein metabolism, length of stay, and mortality rate; and to evaluate the unique metabolic status of sepsis that leads to a search for specific total parenteral nutrition formulas. DESIGN: Prospective, randomized, and multicenter study. SETTING: Intensive care units (ICUs) in seven university hospitals. PATIENTS: Sixty-nine septic patients. MEASUREMENTS AND MAIN RESULTS: The patients were randomized into three groups according to the total parenteral nutrition administered. Group A (n = 22) and B (n = 25) patients received 1.5 g of amino acids/kg/day with a nonprotein ratio of 100:1 calories/g of nitrogen, and a varying branch-chain amino acids percentage (group A [23%); group B [45%]). Group C patients were treated with 1.1 g/kg/day of amino acids with a nonprotein ratio of 140:1 calories/g of nitrogen and 45% branch-chain amino acids. All diets were isocaloric. Prealbumin, retinol-binding protein, nitrogen balance, and plasma amino acid profiles (24 amino acids) were determined at baseline and after 3, 7, and 11 days of total parenteral nutrition. The length of stay and the mortality rate in the ICU were recorded. At baseline (preparenteral nutrition), no differences in age, gender, severity of the condition, or clinical chemistry were found between the groups. Prealbumin and retinol-binding protein increased in groups B (p < .004, p < .002, respectively) and C (p < .001, p < .002, respectively). Plasma arginine increased significantly in group C (p < .05), and plasma valine (p < .0001, p < .04, respectively), leucine (p < .005, p < .03, respectively), and isoleucine (p < .001, p < .0001, respectively) increased significantly in groups B and C. The length of stay in the ICU did not change between the groups. The mortality rate in groups B and C was less than in group A (p < .03). CONCLUSIONS: Our results suggest that the branch-chain amino acids-rich formulas (45%) show a beneficial effect in septic patients.

[Giant gastric stromal tumor simulating a focal hepatic lesion].

Gastrointestinal stromal tumors (GIST), are unusual malignancies regarded for many years as being basically of smooth muscle nature and designated as leiomyomas, leiomyosarcomas or leiomyoblastomas. Histogenesis has been debated, though it is presently accepted that they are characterized by poorly differentiated cells, including tumors showing differentiation towards smooth muscle, neural elements, dual differentiation or lack of differentiation. Another group with ultrastructural and immunohistochemical features similar to those of gastrointestinal autonomic plexus has been described and designated as GAN tumors. Diagnosis and classification of these tumors are not possible using conventional pathological techniques, making ultrastructural and immunohistochemical studies necessary. Accurate classification is clinically essential due to prognostic implications. GIST present with few clinical symptoms even in cases of large tumors and are quite often incidentally found during surgical procedures or in postmortem studies. We report a case of a giant gastric stromal tumor showing differentiation towards smooth muscle which presented as a focal hepatic lesion.
