Prevalence of echocardiographic left ventricular hypertrophy in persons with systemic hypertension, coronary artery disease, and peripheral arterial disease and in persons with systemic hypertension, coronary artery disease, and no peripheral arterial disease.

Echocardiographic left ventricular (LV) hypertrophy was present in 120 of 160 patients (75%) (mean age 72 +/- 8 years) with systemic hypertension, coronary artery disease, and peripheral arterial disease (PAD) and in 43 of 94 age- and gender-matched patients (46%) with systemic hypertension, coronary artery disease, and no PAD (p<0.001). Echocardiographic LV hypertrophy was present in 63 of 68 patients with PAD (93%) with ankle-brachial indexes (ABIs) of <0.60 and in 57 of 92 patients (62%) with ABIs of 0.60 to 0.89 (p<0.001).

Cardioselective beta-blocker use in patients with reversible airway disease.

BACKGROUND: Beta-blocker therapy has mortality benefit in patients with hypertension, heart failure and coronary artery disease, as well as during the perioperative period. These drugs have traditionally been considered contraindicated in patients with reversible airway disease. OBJECTIVES: To assess the effect of cardioselective beta-blockers on respiratory function of patients with reversible airway disease. Reversible airway disease was defined as asthma or chronic obstructive pulmonary disease with a reversible obstructive component. SEARCH STRATEGY: A comprehensive search of EMBASE, MEDLINE and CINAHL was performed using the Cochrane Airways Group registry to identify randomized blinded placebo-controlled trials from 1966 to February, 2000. The search was completed using the terms: asthma*, bronchial hyperreactivity*, respiratory sounds*, wheez*, obstructive lung disease* or obstructive airway disease*, and adrenergic antagonist*, sympatholytic* or adrenergic receptor block*. We did not exclude trials on the basis of language. SELECTION CRITERIA: Randomized, blinded, placebo-controlled trials of single dose or longer duration that studied the effects of cardioselective beta-blockers on the forced expiratory volume in 1 second (FEV1), symptoms and use of short-acting inhaled beta-agonists, in patients with reversible airway disease. Reversible airway disease was documented by response to methacholine challenge, by an increase in FEV1 of at least 15% to beta-agonist administration, or the presence of asthma as defined by the American Thoracic Society. DATA COLLECTION AND ANALYSIS: Two independent reviewers extracted data from the selected articles, reconciling differences by consensus. Cardioselective beta-blockers were divided into 2 groups, those with or without intrinsic sympathomimetic activity (ISA). Two interventions studied were the administration of beta-blocker, given either as a single dose or for longer duration, and the use of beta-agonist given after the study drug. MAIN RESULTS: Nineteen studies for single-dose treatment and 10 for treatment of longer duration met selection criteria. The patients had mild-moderate airways obstruction. For cardioselective beta-blockers taken as a group, administration of a single dose was associated with a 7.98% (CI, 6.19 to 9.77%) reduction in FEV1, but with a 13.16% (CI, 10.76 to 15.56%) increase in beta-agonist response, as compared to placebo. There was no increase in symptoms. After treatment lasting a few days to a few weeks, there was no decrement in FEV1 compared to placebo and no increase in symptoms or inhaler use. Regular use of cardioselective beta-blockers without ISA produced a 13.13% (CI, 5.97 to 20.30) increase in beta-agonist response compared to placebo, a response not seen with beta-blockers containing ISA (-0.60% [CI, -11.7 to +10.5%]). REVIEWER'S CONCLUSIONS: Cardioselective beta-blockers, given to patients with mild-moderate reversible airway disease, do not produce clinically significant adverse respiratory effects in the short term. It is not possible to comment on their effects in patient with more severe or less reversible disease, or on their effect on the frequency or severity of acute exacerbations. Given their demonstrated benefit in conditions such as heart failure, coronary artery disease and hypertension, cardioselective beta-blockers should not be withheld from patients with mild-moderate reversible airway disease.

Corticosteroids for maintaining remission of Crohn's disease.

OBJECTIVES: To evaluate the effectiveness and safety of conventional systemic corticosteroid therapy in maintaining clinical remission in Crohn's disease. SEARCH STRATEGY: A computer-assisted search of the on-line bibliographic database MEDLINE of studies published in English, French, Spanish, Italian and German between 1966 and May, 1998. Manual searches of the reference lists from the potentially relevant studies were performed in order to identify additional studies that may have been missed using the computer-assisted search strategy. Proceedings from major gastrointestinal meetings were also manually searched from 1985 to 1997 in order to identify unpublished studies. The Cochrane Controlled Trials Register and the Inflammatory Bowel Disease Review Group Trials Register were also searched. SELECTION CRITERIA: Randomized double-blind placebo-controlled trials involving patients of any age with Crohn's disease in clinical remission as defined by a CDAI < 150 or by the presence of no symptoms or only mild symptoms at the time of entry into the trial. The experimental treatment consisted of oral conventional corticosteroid therapy (excluding budesonide, fluticasone, etc). Clinical disease relapse was used as the outcome measure of interest. DATA COLLECTION AND ANALYSIS: Eligible studies were selected by 4 reviewers and data were extracted onto standardized data extraction forms. Disagreements in eligibility or data extraction were resolved by consensus. Data were converted into individual 2x2 tables for each study. The presence of significant heterogeneity among studies was tested using the chi-square test. The 2x2 tables were synthesized into a summary test statistic using the pooled odds ratio and 95% confidence intervals as described by Cochran and Mantel and Haenszel (the 'odds ratio' in MetaView). A fixed effects model was used for the pooling of data. MAIN RESULTS: Four studies were initially judged as being eligible for inclusion. After obtaining additional information on one of the studies it was excluded because it was not double-blind. The total number of subjects included in the analysis at the time points of 6, 12 and 24 months were 142, 131 and 95 for the corticosteroid group and 161, 138 and 87 for the control group. The odds ratios for relapse on active treatment and the corresponding 95% confidence intervals were 0.71 (0.39, 1.31), 0.82 (0.47, 1.43) and 0.72 (0.38, 1.35) at 6, 12 and 24 months. The numbers needed to treat with corticosteroids to prevent one additional relapse were 24, 35, 15 respectively. REVIEWER'S CONCLUSIONS: The use of conventional systemic corticosteroids in patients with clinically quiescent Crohn's disease does not appear to reduce the risk of relapse over a 24 month period of follow-up.

Disease system analysis: basic disease progression models in degenerative disease.

PURPOSE: To describe the disease status of degenerative diseases (i.e., type 2 diabetes mellitus, Parkinson's disease) as function of disease process and treatment effects, a family of disease progression models is introduced. METHODS: Disease progression is described using a progression rate (Rdp) acting on the synthesis or elimination parameters of the indirect response model. Symptomatic effects act as disease-dependent or -independent effects on the synthesis or elimination parameters. Protective drug effects act as disease dependent or -independent effects on Rdp. RESULTS: Simulations with the ten disease models show distinctly different signature profiles of treatment effects on disease status. Symptomatic effects result in improvement of disease status with a subsequent deterioration. Treatment cessation results in a disease status equal to the situation where treatment had not been applied. Protective effects result in a lasting reduction, or even reversal, of the disease progression rate and the resulting disease status during the treatment period. After cessation of treatment the natural disease course will continue from the disease status at that point. CONCLUSION: Disease system analysis constitutes a scientific basis for the distinction between symptomatic versus protective drug effects in relation to specific disease processes as well as the identification of the exposure-response relationship during the time-course of disease.

Disease location, anti-Saccharomyces cerevisiae antibody, and NOD2/CARD15 genotype influence the progression of disease behavior in Crohn's disease.

BACKGROUND: Crohn's disease (CD) is characterized by heterogeneity of phenotype. The Vienna classification can be used to classify CD, and recent data illustrate that behavior evolves over the course of the disease. Clinical and biological influences on disease progression remain unclear. We examined the associations of CD disease progression at diagnosis and for up to 20 years of follow-up. METHODS: Two hundred thirty-one well-characterized CD patients were studied. Demographic, clinical, and NOD2/CARD15 data were collected. Disease behavior according to the Vienna classification was assessed at diagnosis and for up to 20 years following diagnosis. RESULTS: At diagnosis, 70% of patients had inflammatory disease, 9% stricturing, and 21% penetrating. Early age at diagnosis was associated with ileocolonic and upper GI disease (p = 0.015), and positive anti-Saccharomyces cerevisiae antibody (ASCA) was associated with ileal involvement (p = 0.008). Smoking was relatively protective against colonic, rather than ileal involvement at diagnosis (p < 0.02). At 20 years, 92% had progressed to a more severe disease type. Patients who progress to a more severe disease type require more frequent surgery (p < 0.00001). Multivariate analysis found disease progression to be associated with ileal disease location (p = 0.001) and positive ASCA (p = 0.003). Variant NOD2/CARD15 alleles were protective against rapid progression of disease phenotype (p = 0.04). The presence of perianal disease was independent of intestinal penetrating disease. CONCLUSIONS: The progression of disease type in CD is associated with the need for more frequent surgery. Rapid progression is associated with ileal disease and positive ASCA, and delayed progression is associated with variant NOD2/CARD15 alleles. Consideration should be given to a separate Vienna classification for perianal disease.

Moderately early (7-14 days) postnatal corticosteroids for preventing chronic lung disease in preterm infants.

BACKGROUND: Corticosteroids have been used late in the neonatal period to treat chronic lung disease (CLD) in preterm babies and early to try to prevent it. CLD is likely to be the result of persisting inflammation in the lung and the use of powerful anti-inflammatory drugs like dexamethasone has some rationale. Early use tends to be associated with increased adverse effects so that studies of moderately early treatment (7-14 days postnatal) might have the dual benefits of fewer side effects and onset of action before chronic inflammation is established. OBJECTIVES: To determine if moderately early (7-14 days) postnatal corticosteroid treatment vs control (placebo or nothing) is of benefit in the prevention and/or treatment of early chronic lung disease in the preterm infant. SEARCH STRATEGY: Randomised controlled trials of postnatal corticosteroid therapy were sought from the Oxford Database of Perinatal Trials, Cochrane Database of Controlled Trials, Medline, hand searching paediatric and perinatal journals, examining previous review articles and information received from practising neonatologists. SELECTION CRITERIA: Randomised controlled trials of postnatal corticosteroid treatment from 7-14 days of birth in high risk preterm infants were selected for this review. DATA COLLECTION AND ANALYSIS: Data regarding clinical outcomes including mortality up to 28 days and before discharge, failure to extubate, mortality and / or chronic lung disease at 28 days and 36 weeks, CLD at 28 days and 36 weeks, infection, hyperglycaemia, hypertension, severe retinopathy of prematurity (ROP), pneumothorax, necrotizing enterocolitis (NEC), gastrointestinal bleeding, severe intraventricular hemorrhage (IVH), hypertrophic cardiomyopathy, late rescue with dexamethasone and abnormal neurological examination at follow-up were abstracted and analysed using Revman 4.0.4. MAIN RESULTS: Moderately early steroid treatment (vs placebo or nothing) reduced mortality by 28 days, chronic lung disease at 28 days and 36 weeks, and death or chronic lung disease at 28 days or 36 weeks. Earlier extubation was facilitated. There was no significant effect on the rates of pneumothorax, severe ROP, and NEC. Adverse effects included hypertension, hyperglycaemia, gastrointestinal bleeding, hypertrophic cardiomyopathy and infection. Steroid-treated infants were less likely to need late rescue with dexamethasone. There was only one small study of longterm follow-up and it did not show any increase in adverse neurological outcome. REVIEWER'S CONCLUSIONS: Moderately early corticosteroid therapy (started at 7-14 days) reduces neonatal mortality and CLD, but at the cost of important short term adverse effects. No reliable evidence concerning long term effects is provided by the trials included in this review. In view of the evidence of an important increase in cerebral palsy and other adverse neurodevelopmental outcomes from trials in which postnatal steroid was begun either earlier or later than 7-14 days, there are reasonable grounds for extending this concern to moderately early initiation of steroid therapy. More research is urgently needed, including long term follow-up of survivors included in previous and any future trials, before the benefits and risks of postnatal steroid treatment, including initiation at 7-14 days, can be reliably assessed.

Biochemical analysis of tau proteins in argyrophilic grain disease, Alzheimer's disease, and Pick's disease : a comparative study.

Although argyrophilic grain disease is characterized histopathologically by tau-positive lesions known as argyrophilic grains located predominantly in limbic brain regions in the absence of other diagnostic neuropathologies, the biochemical correlates of argyrophilic grains in gray and white matter have not been reported. Thus, we analyzed insoluble (pathological) tau proteins in five argyrophilic grain disease brains in comparison with those seen in Alzheimer's disease and Pick's disease. Analyses of separately dissected gray and white matter samples from various cortical regions revealed that pathological tau in argyrophilic grain disease was confined primarily to mediotemporal neocortical gray and adjacent white matter, and also to the allocortex, amygdala, and hippocampus. The amounts of sarcosyl-insoluble tau in all five cases were substantially lower than in Alzheimer's disease and Pick's disease, but the amounts of sarcosyl-insoluble tau in white matter were higher or comparable to that detected in gray matter from the same region, which distinguishes argyrophilic grain disease from Alzheimer's disease. The banding patterns of tau isoforms in argyrophilic grain disease varied: in three cases they were similar to Alzheimer's disease, but in two other cases, 4 microtubule binding repeat (4R) tau predominated, which distinguishes argyrophilic grain disease from classical Pick's disease. The differences between these three diseases were re-enforced by the predominance of straight tau filaments from argyrophilic grain disease brains. Thus, we conclude that argyrophilic grain disease is a distinct tauopathy characterized by prominent accumulation of argyrophilic grains in limbic brain regions in association with the characteristic tau biochemical and ultrastructural profile reported here.

Donepezil for mild and moderate Alzheimer's disease.

BACKGROUND: Alzheimer's disease is the most common cause of dementia and is a primary degenerative disease of the brain of unknown cause. Onset is usually late in life with increasing impairment of memory, developing gradually into a global impairment of cognition, orientation, linguistic ability and judgement. The clinical course is accompanied by growing disability and dependency on care. One of the characteristic features of the disease is the widely variable rate of progression seen in different patients. Acetylcholine is an important neurotransmitter associated with memory, and abnormalities in cholinergic neurones (including cell loss) are among the many neurological and neurochemical abnormalities that develop in AD. One approach to lessening the impact of these abnormalities is to inhibit the breakdown of acetylcholine by blocking the relevant enzyme. Tacrine was the first compound approved as a treatment for AD in the US and worked in this way, but caused severe side effects. E2020 (donepezil, Aricept) is a second generation cholinesterase inhibitor and appears to be highly specific, with relatively few side effects. OBJECTIVES: The objective of this review is to assess whether or not donepezil improves the well-being of patients with mild or moderate Alzheimer's disease. SEARCH STRATEGY: The Cochrane Dementia and Cognitive Impairment Group Register of Clinical Trials, was searched using the terms 'donepezil', 'E2020' and 'ARICEPT'. Medline, PsychLIT and EMBASE electronic databases were searched with the above terms. Members of the Donepezil Study Group and Eisai Inc were contacted. SELECTION CRITERIA: All unconfounded, double-blind, randomised controlled trials in which treatment with donepezil was administered for more than a day and compared with placebo in patients with Alzheimer's disease. DATA COLLECTION AND ANALYSIS: Data were extracted independently by the reviewers (JSB & DB), pooled where appropriate and possible, and the weighted or standardised mean differences or Peto odds ratios (95%CI) estimated. Where possible, intention-to-treat data were used. MAIN RESULTS: There are 4 included trials, covering treatment of 12 or 24 weeks duration in highly selected patients. The only information available on one trial (Gauthier 1998) is a conference abstract which reports no usable results. Available outcome data cover domains including cognitive function and global clinical state, but data on several important dimensions of outcome are not available. The results of three trials suggest a small beneficial effect of donepezil in improving cognitive function: at a 5mg/day dose, improvements measured -2.6 points (95%CI -3.5 -- -1.8) on weighted mean difference, in the midrange of the 70 point ADAS-Cog scale. The results of two trials show some improvement in global clinical state (assessed by an independent clinician) in those treated with donepezil compared to placebo. The patient's own rating of their Quality of Life showed no benefit of donepezil compared with placebo. There were significantly more withdrawals before the end of treatment from the 10mg/d (but not the 5mg/d) donepezil group compared with placebo, which may have resulted in some overestimation of beneficial changes at 10mg/d in progressively declining characteristics, as last available measures were used in analyses. A variety of adverse effects were recorded, but very few patients left a trial as a direct result of the intervention. REVIEWER'S CONCLUSIONS: In selected patients with mild or moderate Alzheimer's disease treated for periods of 12 or 24 weeks, donepezil produced modest improvements in cognitive function and study clinicians rated global clinical state more positively in treated patients. No improvements were present on patient self-assessed quality of life and data on many important outcomes are not available. The practical importance of these changes to patients and carers is unclear.

[Coronary disease risk and prevalence of heart disease in primary care patients with hypertension and renal disease].

INTRODUCTION AND OBJECTIVES: The presence of renal disease significantly alters the cardiovascular risk of patients with high blood pressure. However, few studies have examined renal parameters in primary care patients. The objectives of this study were to investigate cardiovascular risk and the factors influencing it in hypertensive patients with renal disease and to compare the findings with those in hypertensive patients without renal disease. METHODS: The CORONARIA study involved primary care patients with hypertension from all regions of Spain and included two groups with different degrees of renal disease. RESULTS: In total, 703 patients (9.8%) had renal disease. Hypertensive patients with renal disease had a worse cardiovascular risk profile than other hypertensives. The prevalence of diabetes was double in patients with renal disease. Moreover, the risk of a coronary event was significantly higher in those with renal disease. One-third of hypertensives with renal disease had another previously diagnosed cardiovascular disease. In addition, they more frequently had a history of angina, were twice as likely to have had a myocardial infarction, and were more than twice as likely to have undergone revascularization or to have peripheral vascular disease or cerebrovascular disease. Heart failure was four times more frequent in these patients with renal disease than in other hypertensives. CONCLUSIONS: Patients with hypertension and renal disease have a higher risk of cardiovascular disease, exhibit an increased prevalence of diabetes, and suffer from more extensive target organ damage.

[Monoamine oxidase activity in brain regions and organs of patients with Parkinson's disease and Huntington's disease and serum MAO activity of patients with Huntington's disease as compared with neurologically healthy individuals (author's transl)].

The MAO activity (tyramine substrate) was measured in 17 different brain regions, the spinal cord, and 13 different organs of four patients with Huntington's disease and three patients with Parkinson's disease. The values were compared with those measured in corresponding tissues from neurologically healthy patients. The serum MAO activities of 12 patients with Huntington's disease were compared with those of 137 normal persons (benzylamine substrate). A comparison of the MAO activities in the brain regions of patients with Huntington's disease, Parkinson's disease, and normal controls showed only minor differences in the cerebral gray matter, corpus callosum, striatum, caudate nucleus, pons, putamen, nucleus niger, dentatus, cerebellar gray matter, and cerebellar white matter. Larger differences in MAO activity were observed in the Ammon's horn, the striatal fundus, and the olfactory region. Slightly increased MAO activities were found in the pallidum of patients with Huntington's disease and Parkinson's disease. In patients with Huntington's disease the MAO activity is considerably increased in the medulla oblongata (25%) and the spinal cord (nearly 50%) as compared to patients with Parkinson's disease and normal controls. The brain MAO activity in the rat remained unchanged after movement anomalies had been induced by application of 2,3-diaminobutyric acid; the neurolathyrogenic substance iminodipropionitrile (IDPN), which causes chloreiform movements in the rat that last for life did not considerably change the MAO activity of the brain. The enzyme values were essentially the same in pancreas, spleen, kidney, adrenal, jejunum, ileum, colon, rectum, and testis of patients and control individuals. The MAO activities in the thyroid glands of patients with Parkinson's disease and Huntington's disease were slightly reduced in comparison with the control group. MAO activity in the liver of patients with Huntington's disease was reduced to approximately 50%. In the heart it was increased by approximately 30%, and that in the lungs was five times higher. A comparison of serum MAO activities in Huntington's disease patients and normal subjects did not reveal any essential differences. The increased MAO values in the sera of female patients with Huntington's disease may be related to hormonal influences.

Quality of life in Korean patients with inflammatory bowel diseases: ulcerative colitis, Crohn's disease and intestinal Behçet's disease.

Health-related quality of life (HRQOL) is an important outcome factor in chronic diseases such as inflammatory bowel disease (IBD). This study used the Korean translation of the disease-specific, self-administered Inflammatory Bowel Disease Questionnaire (IBDQ) to compare HRQOL in ulcerative colitis (UC; n = 98), Crohn's disease (CD; n = 49), and intestinal Behçet's disease (BD; n = 34). In addition to the current status, patients were asked retrospectively to recall their symptoms at the beginning and during the worst period of their disease. Disease activity was measured by St. Mark's Activity Index, Crohn's disease Activity Index (CDAI), and the Harvey-Bradshaw Index (HBI). In all IBD patients, including those with BD, the IBDQ total score during the worst period was significantly lower than that at present and that at the beginning of the disease. However, there were no significant differences between groups regarding the total IBDQ score or its various dimensions. In UC a strong correlation between IBDQ scores and St. Mark's Activity Index was observed (r = -0.708, P < 0.001). IBDQ scores were also highly correlated with CDAI and HBI in both CD (r = -0.506, P < 0.001 for CDAI; r = -0.600, P < 0.001 for HBI) and BD (r = -0.687, P < 0.001 for CDAI; r = -0.531, P < 0.001 for HBI). However, the current IBDQ score was not related to demographic parameters such as gender, age, educational status, economic status, and marital status as well as disease factors such as duration of disease, history of operation or hospital admission, extent of disease in UC, involved region in CD, and clinical type in BD. We conclude that the Korean IBDQ is a responsive and promising instrument for measuring HRQOL of IBD patients in clinical trials. In addition, the IBDQ can be helpful in developing a disease-specific activity index in BD.

Galantamine for Alzheimer's disease.

BACKGROUND: Galantamine (also called galanthamine, marketed as Reminyl (Janssen)) can be isolated from several plants, including daffodil bulbs, and now synthesized. Galantamine is a specific, competitive, and reversible acetylcholinesterase inhibitor. It is also an allosteric modulator at nicotinic cholinergic receptor sites potentiating cholinergic nicotinic neurotransmission. A small number of early studies showed mild cognitive and global benefits for patients with Alzheimer's disease, and recently several multicentre clinical trials have been published with positive findings. Galantamine has received regulatory approval in Sweden, is available in Austria, and awaits marketing approval in the United States, Europe, and other countries. OBJECTIVES: The objective of this review is to assess the clinical effects of galantamine in patients with probable Alzheimer's disease, and to investigate potential moderators of an effect. SEARCH STRATEGY: The Cochrane Dementia Group specialized register of clinical trials was searched using the terms 'galantamine,' and 'galanthamine' (15 February 2000) as was the Cochrane Controlled Trials Register (2000, Issue 2). These terms were also used to search the following databases: EMBASE, MEDLINE, PsychLit; Combined Health Information Database, NRR (National Research Register), ADEAR (Alzheimer's Disease Education and Referral Centre clinical database, BIOMED (Biomedicine and Health), Glaxo-Wellcome Clinical Trials Register, National Institutes of Health Clinical Trials Databases, Current Controlled Trials, Dissertation Abstracts (mainly North American dissertations) 1961-1994, Index to UK Theses (British dissertations) 1970-1994. Published reviews were inspected for further sources. Additional information was collected from an unpublished investigational brochure for galantamine. SELECTION CRITERIA: Trials selected were randomized, double-blind, parallel-group, and unconfounded comparisons of galantamine with placebo for a treatment duration of greater than 4 weeks in people with Alzheimer's disease. DATA COLLECTION AND ANALYSIS: Data were extracted independently by the reviewers and pooled where appropriate and possible. The pooled odds ratios (95%CI) or the average differences (95%CI) were estimated. Intention-to-treat and observed cases data were both reported, if the data were available to be reported. -Outcomes of interest include the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), clinical global impression of change (CIBIC-plus or CGIC), Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL), Disability Assessment for Dementia scale (DAD) and Neuropsychiatric Inventory (NPI). - Potential moderating variables of a treatment effect included trial duration and dose. MAIN RESULTS: Seven trials were identified that met criteria for entry, with 6 being Phase II or III industry-sponsored multicentre trials. One was of 12 weeks duration; one of 5 months; one of 29 weeks; and the rest of 6 months duration. Trials of 5 months or more were aggregated in the analyses as '6 months'. Overall, galantamine showed significant treatment effects at daily doses of 16-32 mg/d for trials of 3- to 6-months duration. For global ratings, trials of 3 months duration with doses of 24-32mg/d (Odds Ratio (OR) 2.2; 95%CI 1.4 to 3.7) and 36mg/d (OR 3.3; 95%CI 1.2 to 9.3) were statistically significant in favour of treatment. For trials of 6 months duration (5-months to 29 weeks), only doses of 8mg/d failed to be statistically significant (24mg: OR 2.0; 95%CI 1.5 to2.5; 32mg: OR 1.9; 95%CI 1.4 to 2.5). For cognitive function over 6 months duration: at a 24mg/d, improvements measured -3.5 points (k=3; 95%CI -4.3 to -2.8) on weighted mean difference on the ADAS-Cog scale, and -4.0 points at 32mg/d (k=2; 95%CI -5.0 to -3.0). Both observed cases (WMD 3.8; 95%CI 0.3 to 7.3) and intention to treat analyses using the Disability Assessment of Dementia gave statistically significant results in favour of treatment for daily doses of 32mg for 6 months duration. The small number of trials available for analysis, however, limited the power of analyses to detect differences. Galantamine consistently failed to show statistically significant treatment effects at doses of 8mg/day. Galantamine's adverse effects appear similar to those of other cholinesterase inhibitors, in that it tends to produce gastrointestinal effects acutely and with dosage increases. Overall, people treated with galantamine at doses of 24-32 mg/d were more likely to discontinue participation in most trials than were people treated with lower doses or placebo, but in the one trial with a slower rate of titration the discontinuation rate was not significantly greater than placebo for the 16 mg/day dose.

Serum immune responses predict rapid disease progression among children with Crohn's disease: immune responses predict disease progression.

BACKGROUND AND AIM: Crohn's disease (CD) is a heterogeneous disorder characterized by diverse clinical phenotypes. Childhood-onset CD has been described as a more aggressive phenotype. Genetic and immune factors may influence disease phenotype and clinical course. We examined the association of immune responses to microbial antigens with disease behavior and prospectively determined the influence of immune reactivity on disease progression in pediatric CD patients. METHODS: Sera were collected from 196 pediatric CD cases and tested for immune responses: anti-I2, anti-outer membrane protein C (anti-OmpC), anti-CBir1 flagellin (anti-CBir1), and anti-Saccharomyces-cerevisiae (ASCA) using ELISA. Associations between immune responses and clinical phenotype were evaluated. RESULTS: Fifty-eight patients (28%) developed internal penetrating and/or stricturing (IP/S) disease after a median follow-up of 18 months. Both anti-OmpC (p < 0.0006) and anti-I2 (p < 0.003) were associated with IP/S disease. The frequency of IP/S disease increased with increasing number of immune responses (p trend = 0.002). The odds of developing IP/S disease were highest in patients positive for all four immune responses (OR (95% CI): 11 (1.5-80.4); p = 0.03). Pediatric CD patients positive for > or =1 immune response progressed to IP/S disease sooner after diagnosis as compared to those negative for all immune responses (p < 0.03). CONCLUSIONS: The presence and magnitude of immune responses to microbial antigens are significantly associated with more aggressive disease phenotypes among children with CD. This is the first study to prospectively demonstrate that the time to develop a disease complication in children is significantly faster in the presence of immune reactivity, thereby predicting disease progression to more aggressive disease phenotypes among pediatric CD patients.

Clinical presentation of Crohn's disease. association between familial disease, smoking, disease phenotype, extraintestinal manifestations and need for surgery.

BACKGROUND/AIMS: Recent molecular data suggest that genetic factors may underlie the disease heterogeneity observed in Crohn's disease (CD). It was also suggested that familial inflammatory bowel disease (IBD) is a homogenous subgroup, phenotypically different from sporadic disease. Our aim was to determine the clinical presentation in a large CD population. METHODOLOGY: 564 CD patients (m/f: 278/286, age: 37.4 (SD 12.7) yrs, duration: 8.4 (7.1) yrs) were included. Disease phenotype was determined according to Vienna classification. Familial disease, extraintestinal manifestations (EIM), need for surgery and smoking habits were also analyzed. RESULTS: Familial IBD was present in 73 (12.9%) patients. Age at onset and presence of EIMs was associated with familial disease. Penetrating (44.6% vs. <10 yrs: 29.1%, P<0.0001) and ileocolonic disease (54.4% vs. 42.8%, P=0.03) were more common in patients with a disease duration of > or =10 yrs. In a logistic regression model female gender, colonic/ileocolonic location, smoking and familial IBD were independent risk factors for EIMs, while ileal and non-inflammatory disease increased the risk for resections. Smoking was also associated with frequent relapses. CONCLUSIONS: Familial IBD was associated with the presence of EIMs, while ileal involvement and noninflammatory behavior independently increased the risk for surgery. Since penetrating and extensive disease was more frequent in patients with longer disease duration our data support a possible change in location and behavior during the course of disease.

Morbidity after total thyroidectomy for benign thyroid disease: comparison of Graves' disease and non-Graves' disease.

The purpose of this study was to review the safety of total thyroidectomies for benign thyroid disease, with special emphasis on the comparison between Graves' disease and non-Graves' disease. In this study, 107 patients who underwent total thyroidectomies for clinically benign thyroid disease performed by the same surgeon between January 1987 and December 2004 were enrolled; 48 had Graves' disease and 59 had non-Graves' disease. The rates of temporary vs. permanent hypoparathyroidism, hematoma requiring surgical intervention, and temporary vs. permanent recurrent laryngeal nerve palsy (RLNP) after total thyroidectomy for benign thyroid disease were 34.6% vs. 3.7%, 6.5%, and 6.5% vs. 1.85%, respectively. The rates of permanent hypoparathyroidism and temporary RLNP in the Graves' disease group were significantly different when compared with the non-Graves' disease group (8.3% vs. 0% and 11.5% vs. 2.5%, respectively). However, comparing the rates of temporary hypoparathyroidism, permanent RLNP, and postoperative hematoma, there was no statistically significant difference. Compared with total lobectomy, the rates of postoperative hematoma increased significantly for total thyroidectomy (6.5% vs. 0.48%). Total thyroidectomy for non-Graves' benign thyroid disease may be performed with minimal morbidity as has been advocated by many authors. For patients with Graves' disease in this study, however, the complication rates of permanent hypoparathyroidism and temporary RLNP were significantly increased. Therefore, we suggest that total thyroidectomy for Graves' disease should be performed by an experienced surgeon.

[Celiac disease and autoimmune diseases or systemic disease. Six cases and a review of the literature].

BACKGROUND: Celiac disease is an autoimmune disorder which may be associated with another autoimmune or systemic disease. OBJECTIVE: To determine the links between autoimmune diseases and celiac disease. PATIENTS AND METHODS: Among 31 patients with a celiac disease, we selected those who had another autoimmune or systemic disease. RESULTS: We report 6 patients with such disease association: 3 with autoimmune thyroiditis including one also with Grave's disease, 2 with systemic lupus erythematosus including one also with insulin-dependent diabetes mellitus, and 1 with temporal arteritis. CONCLUSION: The link between celiac disease and autoimmune thyroiditis or insulin-dependent diabetes mellitus seems to be real but many discrepancies are observed for the other autoimmune diseases. After a literature review, we suggest a summary of effective associations between celiac disease and autoimmune or systemic diseases.
