Atorvastatin therapy improves exercise oxygen uptake kinetics in post-myocardial infarction patients

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 6 2007
M. Guazzi
Abstract Background Statins represent a modern mainstay of the drug treatment of coronary artery disease and acute coronary syndromes. Reduced aerobic work performance and slowed VO2 kinetics are established features of the clinical picture of post-myocardial infarction (MI) patients. We tested the hypothesis that statin therapy improves VO2 exercise performance in normocholesterolaemic post-MI patients. Materials and methods, According to a double-blinded, randomized, crossover and placebo-controlled study design, in 18 patients with uncomplicated recent (3 days) MI we investigated the effects of atorvastatin (20 mg day,1) on gas exchange kinetics by calculating VO2 effective time constant (tau) during a 50-watt constant workload exercise, brachial artery flow-mediated dilatation (FMD) as an index of endothelial function, left ventricular function (echocardiography) and C-reactive protein (CRP, as an index of inflammation). Atorvastatin or placebo was given for 3 months each. Results, Atorvastatin therapy significantly improved exercise VO2 tau and FMD, and reduced CRP levels. We did not observe changes in cardiac contractile function and relaxation properties during all study periods in either group. Conclusions, In post-MI patients exercise performance is a potential additional target of benefits related to statin therapy. Endothelial function improvement is very likely implicated in this newly described therapeutic property. [source]


Predictive value of renal histological changes for postoperative renal function improvement in children with congenital ureteropelvic junction stenosis

INTERNATIONAL JOURNAL OF UROLOGY, Issue 6 2002
Ahmet Erbagci
Abstract Background: The aim of this study was to evaluate the relationship between renal function, as measured by diuretic radionuclide renography, and the outcome of pyeloplasty. A study was designed to evaluate renal parenchymal biopsy specimens derived from children undergoing corrective surgery for ureteropelvic junction (UPJ) stenosis, and compare these to preoperative and postoperative renal function status. Methods: Thirty-five children with congenital unilateral UPJ stenosis were evaluated. In addition to all conventional diagnostic procedures for UPJ stenosis, differential renal functional (DRF) activity was assessed in each of these children by obtaining 99mTc diethylenetriaminepentaacetic acid renogram curves. All children underwent dismembered pyeloplasty, and follow-up renogram evaluation was conducted 6 and 12 months after surgical repair. Biopsy specimens from renal cortical regions obtained during the surgical correction of UPJ stenosis were evaluated, and changes in renal histology were graded from I to V according to their severity. Spearman's correlation test was used to compare the histological evaluation results and the basal, 6- and 12-month follow-up DRF findings. A Wilcoxon paired test was used to evaluate statistical differences between values. Results: The findings showed a positive correlation between the severity of histological changes and DRF activity. All kidneys (22) with a DRF activity value of < 40% preoperatively demonstrated at least grade III changes when biopsy specimens were examined. Of children with a DRF activity value > 40% (13), only three showed severe histological changes. Histological grades were correlated between basal (r = ,0.4; P = 0.019), 6-month (r = 0.54; P = 0.002) and 12-month (r = 0.54; P = 0.02) findings. In the Wilcoxon paired test, there was a statistically significant difference between basal and 6-month values (P < 0.05), and also between basal and 12-month values (P < 0.01). There was no statistically significant difference between 6- and 12-month values (P > 0.20). Conclusion: Comparative evaluation of postoperative renal function with DRF activity and renal parenchymal histological alterations revealed a close correlation in terms of renal function improvement potential following reconstructive surgery in children with UPJ stenosis.

LIVER TRANSPLANTATION, Issue 5 2007
Isabelle Morard
Sirolimus (SRL) has been proposed to replace calcineurin inhibitors (CNI) in case of CNI-induced toxicity. The aim of this study was to evaluate the efficacy and safety of conversion from CNI to SRL in maintenance liver transplantation (LT) patients. Between 2002 and 2006, conversion was performed in 48 patients (17 female, 31 male; mean age 57 ± 10 yr) after a median delay of 19.4 months (range 0.2,173 months) after LT. Indication for conversion was renal impairment (RI) (78%), CNI neurotoxicity (13%), or post-LT cancer (9%). Median follow-up was 22.6 ± 11 months. Median SRL dosage and trough levels were 2.4 ± 1.3 mg and 8.1 ± 2.7 ,g/L. Immunosuppression consisted of SRL alone (33%), or SRL + mycophenolate mofetil (MMF) (39%), SRL + prednisone (15%), SRL + CNI (4%), or SRL + MMF + prednisone (8%). Mean glomerular filtration rate (GFR) improved from 33 to 48 mL/minute in patients with severe RI (P = 0.022) and from 56 to 74 mL/minute in patients with moderate RI (P = 0.0001). After conversion, main complications were albuminuria (36%), hyperlipidemia (49%), dermatitis (14%), edema (14%), oral ulcers (12%), joint pain (4%), infection (2%), and pneumonia (2%). Acute rejection (AR) occurred in 17% of the patients. SRL was withdrawn in 17% of the patients. In conclusion, conversion from CNI to SRL is safe and is associated with significant renal function improvement. Liver Transpl 13:658,664, 2007. © 2007 AASLD. [source]


Results from different patient populations using combined therapy with alprostadil and sildenafil: predictors of satisfaction

BJU INTERNATIONAL, Issue 4 2000
J.H. Mydlo
Objective To evaluate the outcome of combined therapy (using intraurethral alprostadil and oral sildenafil) in private and clinic patients with erectile dysfunction, and thus assess predictors of satisfaction. Patients and methods In all, 360 men were treated for erectile dysfunction using single and/or combined therapy, comprising 214 private-practice and 166 clinic patients. Responses were evaluated using the International Index for Erectile Function (IIEF) questionnaire before and after treatment. Serum testosterone levels, education and socio-economic status were also assessed. Group 1a consisted of 33 private patients and Group 1b of 24 clinic patients who tried the maximum dose of intraurethral alprostadil monotherapy initially, followed by the maximum dose of sildenafil monotherapy, and remained dissatisfied. Group 2a consisted of 32 private patients and group 2b of 31 clinic patients who tried the maximum dose of sildenafil monotherapy initially, followed by the maximum dose of alprostadil monotherapy, and were also dissatisfied. These two groups of 65 private and 55 clinic patients then underwent combined therapy. Results The mean ( sd) score for erectile function was 24.1 (2) for combined therapy (a 123% improvement), and 19.8 (1.8) (83% improvement) and 15.2 (1.6) (41% improvement) for sildenafil and alprostadil monotherapies (P < 0.05 for both patient groups). The men also reported an improvement in their satisfaction with intercourse. However, at 18 months, 60 of the 65 private patients but only 40 of the 55 clinic patients continued with combined therapy; thus, the discontinuation rate was three times greater among clinic than among private patients. Furthermore, the private patients had an overall improvement in the satisfaction score of 128%, compared with 51% for the clinic patients. Conclusion Although there were no significant differences in erectile function improvement within the two satisfied combined therapy groups, the differences in overall satisfaction and long-term withdrawal rates suggests that other factors beside motivation must be involved for success, e.g. education, persistence, realistic expectations, and certain psychological factors. Combined therapy should be considered for those patients who have a suboptimal response to monotherapy and refuse or are not candidates for surgical options. Generally, those patients with a higher education, greater persistence and more realistic expectations were more satisfied with combined therapy. [source]


Comparison of early telescope loading of non-submerged ITI implants in irradiated and non-irradiated oral cancer patients

CLINICAL ORAL IMPLANTS RESEARCH, Issue 4 2006
Constantin Alexander Landes
Abstract Objective: To compare early dental implant loading in irradiated and non-irradiated oral cancer patients in order to accelerate masticatory function improvement and quality of life. Patients and methods: One hundred and fourteen non-submerged interforaminal ITI implants were early loaded in 30 patients after 3 weeks in situ (telescoped overdenture). Nineteen patients received 72 implants (63%) after local irradiation; 11 non-irradiated patients received 42 implants (37%) with a 24-month follow-up. Results: At 24 month follow-up, one early failure had occurred in an irradiated patient (=99% functioning implants in situ). Peri-implant bleeding and plaque index were similarly high in both groups (40 to 68% average). The Results of other measured parameters were as follows (values for mean; irradiated; non-irradiated patients with respective standard deviations; significance of comparison): bone loss (0.9±0.9; 1.4±0.9; 0.4±0.5 mM; P<0.01); Periotest® score (,2.7±2.7; ,2.4±2.2; ,3.1±3.3; P<0.2); gingival recession (0.6±0.7 mM; 0.8±0.9 mM; 0.4±0.5 mM, P<0.02); and peri-implant probing depths (3±1.2; 2.6±0.6; 3.4±1.7 mM; P<0.002). Conclusion: The results suggest reliable non-submerged implantation and early loading. However, bone loss in irradiated mandibles, combined with higher average Periotest values and gingival recession in an oral environment of altered saliva quantity, quality, microflora and local scarring, requires extended follow-up.

Abstract BACKGROUND:Chlorella vulgaris is a unicellular and microscopic algae that is currently used in a variety of forms of tablets, capsules and liquid as a biological response modifier. The aim of this study was to investigate the effects of hydrolyzed Chlorella vulgaris by malted barley for its potential reduction of the immobility time in ICR mice and on the cytokine regulation in human T cell line, Molt-4. RESULTS: After a forced swimming test, the changes in aspects of blood biochemical parameters due to the administration of hydrolyzed Chlorella vulgaris by malted barley were examined. The effect of hydrolyzed Chlorella vulgaris by the malted barley-treated group for 14 days on the immobility time was significantly reduced in comparison with that of the control group (P < 0.01). The plasma level of blood urea nitrogen was significantly decreased in hydrolyzed Chlorella vulgaris by malted barley-treated group compared with the control group (P < 0.05). In addition, hydrolyzed Chlorella vulgaris by malted barley increased interferon-, and interlukin-2 levels in Molt-4 cells. CONCLUSION: These results indicate that hydrolyzed Chlorella vulgaris by malted barley is useful for immune function improvements, enhanced physical stamina, and as a candidate for an anti-fatigue or antidepressant agent.

Inhaled steroids for all children with asthma? Some children with mild well-controlled asthma may not need a daily inhaled steroid, a Scandinavian study suggests (Arch Dis Child 2008;93:654-9). A total of 176 children aged 5-10 years were randomised to treatment with cromoglicate (Intal) or budesonide. Initially high doses of budesonide (400,g twice daily) were reduced after one month to 200,g twice daily for four months; subsequent treatment for a further year was 100,g twice daily as required for exacerbations or 100,g twice daily regularly. Budesonide was associated with greater improvement in lung function and fewer exacerbations compared with cromoglicate, but after 18 months lung function improvements did not differ. Regular budesonide was associated with fewer exacerbations than as-required administration (0.97 vs 1.69 per patient in months 7-18) but no difference in asthma-free days or use of rescue medication. Growth suppression was slightly greater with continuous budesonide. Interventions to reduce atypicals weight gain A systematic review has found that techniques such as cognitive behaviour therapy and nutritional counselling can reduce weight gain associated with atypical antipsychotics (Br J Psychiatry 2008;193:101-7). Analysis of 10 randomised trials lasting eight weeks to six months found that nonpharmacological intervention increased mean weight loss by about 2.5kg compared with usual care. Check flu vaccine delivery Production of flu vaccine is proceeding according to plan, the Director of Immunisation has told GPs. Practices should now contact their suppliers to confirm a delivery schedule so that clinics can be arranged. New BNF for Children The fourth BNF for Children has been published, containing new sections on HPV vaccination, contraception, treatment of pelvic inflammatory disease and the use of continuous iv infusions in neonates. BNFC 2008 is available online at bnfc.org/bnfc. MMR catch-up ,urgent' The DoH has called for urgent action to reduce the risk of a measles epidemic. Following years of relatively low uptake of MMR vaccine, the pool of unprotected children is now large enough to raise the prospect of 30 000-100 000 measles cases in England. A catch-up campaign will now target children and young people who have never been vaccinated, followed by those who have not completed their course of immunisation. Resource materials are available at www.immunisation.nhs.uk. , A new brand of MMR vaccine is now available. Sanofi Pasteur MSD has replaced MMRII with a new formulation and presentation, MMRvaxPro. The new vaccine is equivalent to its predecessor and interchangeable with Priorix. Early primary prevention with low-dose aspirin? GPs should consider prescribing low-dose aspirin for primary prevention for men aged 48 and women aged 57, say UK researchers (Heart 2008; published online 15 August 2008. doi:10.1136/hrt.2008.150698). Using data from the THIN network of electronic patient records, they modelled the age at which 10-year coronary risk changed from <10 per cent to >10 per cent in men and women without diabetes, not taking lipid-lowering therapy and with no history of cardiovascular disease. Does COPD therapy slow progression? Treatment with an inhaled steroid and long-acting beta-agonist may slow progression of COPD, according to a new analysis of the TORCH study (Am J Respir Crit Care Med 2008;178:332-8). TORCH was designed to determine the effects of COPD treatment on mortality; the primary analysis found no significant difference between fluticasone/salmeterol (Seretide) and placebo (N Engl J Med 2007;356:775-89). This analysis found that the rate of decline in FEV1 (a marker of disease progression) was significantly greater with placebo (55ml per year) than with salmeterol or fluticasone monotherapy (both 42ml per year) or their combination (39ml per year). Faster decline in FEV1 was associated with current smoking, lower BMI and more frequent exacerbations. Copyright © 2008 Wiley Interface Ltd [source]
