RESUMO

BACKGROUND: Little is known about the benefits of lipid-lowering medications in those age ≥ 75 years. We assessed the effect of lipid-lowering medications on progression to severe atherosclerosis in patients age > 75. METHODS: Data was retrospectively obtained from the Stroke Prevention & Atherosclerosis Research Centre, Canada. Atherosclerosis burden was measured as carotid total plaque area (TPA), a powerful predictor of cardiovascular risk. Survival time free of severe atherosclerosis (SFSA) was defined as the period when TPA remained <1.19 cm2. Kaplan-Meier, multiple Cox proportional hazard and hierarchical mixed-effect models were used to determine the effects of lipid-lowering medications on progression to severe atherosclerosis. RESULTS: In total 1404 cases (mean age 81 ± 4 years; women 52%) were included. Those taking lipid-lowering medications were more likely to have a history of diabetes and a higher burden of atherosclerosis at baseline. In Kaplan-Meier analysis, the SFSA was significantly longer in those receiving lipid-lowering therapy. In multivariable-adjusted analyses, those not receiving lipid lowering therapy (irrespective of their vascular disease at baseline) were more likely to have TPA > 1.19 cm2 (hazard ratio (HR) = 1.37, 95% confidence interval (CI): 1.09,0.71). Similar findings were observed in mixed effects models when plaque progression was defined as any change >0.05 cm2 per year (odds ratio (OR):2.17, 95% CI:1.38,3.57). CONCLUSION: Lipid-lowering therapy is effective in controlling the burden of atherosclerosis among older adults with and without vascular disease. The measurement of plaque burden can guide selection and follow-up of those who may benefit from treatment.

RESUMO

BACKGROUND: This systematic review and meta-analysis aimed to determine whether the combination of hydrocortisone, vitamin C (ascorbic acid), and thiamine (HAT therapy) diminishes the mortality and is effective in expediting the resolution of sepsis and septic shock or not. METHODS: The following databases of PubMed, Scopus, ISI Web of Science, and Google Scholar were explored until March 2021 for all existing literature related to this field. An automatic alert for all databases was also activated to update our search. Meta-analysis was performed on clinical trials and cohorts separately as well as on all the pooled populations. RESULTS: This study evaluated nine clinical trials (1358 participants) and nine cohorts (339,437 participants) and is the most comprehensive systematic review in this field. The results of our meta-analysis demonstrated a significant difference in the reduction of Sepsis-Related Organ Failure Assessment (SOFA) score changes (Δ-SOFA) over 72 h (Standard Mean Difference (SMD) = -0.429; 95% CI: -0.737, 0.120; P = 0.006), duration of vasopressor (VP) (SMD = -0.373; 95% CI: -0.619, -0.128; P = 0.003), and procalcitonin (PCT) clearance (SMD = 0.496; 95% CI: 0.061, 0.931%; P = 0.026). Considering the results of cohorts, HAT therapy was effective in the survival of intensive care units (ICUs) patients (OR = 0.641; 95% CI: 0.423-0.970, P = 0.035). However, no significant difference was observed between the intervention and control groups in hospital mortality (Odds Ratio (OR) = 0.811, 95% CI: 0.544-1.209, P = 0.304), 28- to 30-day mortality (OR = 1.000; 95% CI: 0.782-1.279, P = 0.998), new onset acute kidney injury requiring renal replacement therapy ((OR = 0.856, 95% CI: 0.526, 1.391; P = 0.529), in-hospital length of stay (LOS) (SMD = 0.090; 95% CI: -0.036, 0.216 days; P = 0.162), LOS in ICU (SMD = 0.016, 95% CI: -0.138, 0.170 days; P = 0.838), and mechanical ventilation-free days (SMD = 0.004; 95% CI: -0.154, 0.163 days; P = 0.956). CONCLUSION: Supplementation of septic and septic shock patients with HAT therapy has significant beneficial effects on SOFA score over 72 hours, duration of exogenous vasopressor infusion and procalcitonin clearance. Considering the results of cohort studies, supplementation with HAT is efficacious in reducing ICU mortality.

RESUMO

COVID-19 disease manifests itself in a wide range of signs and symptoms, beginning with mild symptoms, such as fever, cough, and dyspnea, progressing to acute respiratory distress syndrome (ARDS) and death in some cases. The cytokine storm, or an excess of cytokines released locally, is assumed to be the primary cause of ARDS and mortality in COVID-19 patients. To enhance the survival rate of COVID-19 patients, early management of the cytokine storm with immunomodulators is crucial. Although the effectiveness of some immunosuppressants, such as corticosteroids and tocilizumab, has been studied in clinical trials, the administration of these drugs should be exercised cautiously. Cannabidiol (CBD) is a non-psychotropic phytocannabinoid from Cannabis sativa extracts with anti-inflammatory properties. This review is intended to discuss the possible utility of CBD for the management of COVID-19 patients, particularly those with ARDS.

RESUMO

BackgroundImmunocompromised patients have lower seroconversion rate in response to COVID-19 vaccination. The aim of this study is to evaluate the humoral immune response with short-term clinical outcomes in solid organ transplant recipients vaccinated with SARS-CoV-2 vaccine (BBIBP-CorV; Sinopharm).MethodsThis prospective cohort was conducted from March to December 2021 in Abu Ali Sina hospital, Iran. All transplant recipients, older than 18 years were recruited. The patients received two doses of Sinopharm vaccine 4 weeks apart. Immunogenicity was evaluated through assessment of antibodies against the receptor-binding domain (RBD) of SARS-CoV-2 after the first and second dose of vaccine. The patients were followed up for 6 months after vaccination.ResultsOut of 921 transplant patients, 115 (12.5%) and 239 (26%) had acceptable anti S-RBD immunoglobulin G (IgG) levels after the first and second dose, respectively. Eighty patients (8.68%) got infected with COVID-19 which led to 45 (4.9%) of patients being hospitalized. None of the patients died during follow-up period. Twenty-four (10.9%) liver transplant recipients developed liver enzyme elevation, and increased serum creatinine was observed in 86 (13.5%) kidney transplant patients. Two patients experienced biopsy-proven rejection without any graft loss.ConclusionOur study revealed that humoral response rate of solid organ transplant recipients to Sinopharm vaccine was low.

RESUMO

INTRODUCTION: Delirium is one of the most prevalent complications in intensive care unit (ICU) patients, which is related to worse clinical outcomes including a longer ICU stay, longer duration of mechanical ventilation, higher mortality rates and increased risk of cognitive impairment. Observational studies have suggested that statins might have a positive effect on delirium status of hospitalized patients. To date, there has been no trial assessing the effect of atorvastatin on delirium status in critically ill patients. Thus, the aim of the current study was to determine the efficacy of atorvastatin on delirium status of patients in the ICU. METHODS: In this randomized, double-blind and controlled trial, a total of 90 patients in the general ICU who had delirium for at least 2 days were randomly divided into atorvastatin (40 mg/day) (n = 40) and control (n = 50) groups. Delirium status of the patients was determined twice a day at 10:00 a.m. and 18:00 p.m. using the Richmond Agitation-Sedation Scale (RASS). RESULTS: Administration 40 mg/day of atorvastatin significantly reduced the mean RASS score and increased delirium-free days at both morning and afternoon time points compared to the control group (p < 0.05). CONCLUSIONS: Administration of atorvastatin had a significant positive effect on delirium status in patients admitted to the ICU.

RESUMO

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility, for which the insulin sensitizer metformin has been used therapeutically. It has been shown that curcumin also exhibits insulin-sensitizing properties. Given that metformin acts as an ovulation inducing agent and both curcumin and metformin can reduce insulin resistance, the aim of the current study was to evaluate the effect of metformin with and without curcumin nanomicelles in the treatment of women with polycystic ovary syndrome. This clinical trial was conducted on 100 women with PCOS, diagnosed according to the Rotterdam criteria, who were sequentially recruited and randomly divided into two groups (n = 50 each). Group 1 received 500 mg metformin three times daily and group 2 received 80 mg/day capsule of curcumin nanomicelle and 500 mg metformin three times a day for 3 months. After collecting fasting blood samples, biochemical parameters including triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol, plasma glucose, alanine amino transferase (ALT) and aspartate aminotransferase (AST) were evaluated based on enzymatic methods. Hormonal parameters were assessed using immunoassay kits. Insulin resistance (HOMA-IR) and insulin-sensitivity check index (QUICKI) were also assessed. After treatment, fasting insulin, HOMA-IR, and total testosterone in group 2 were significantly lower than those in group 1 (p < 0.05). Post-treatment LDL-C levels in groups 1 and 2 were 117.9 ± 24 and 91.12 ± 19.46 mg/dL, respectively (p < 0.01). In addition, HDL-C levels were increased with curcumin (group 1: 38.1 ± 4.36 mg/dL; group 2: 44.12 ± 7.3 mg/dL, p < 0.05). Total cholesterol was decreased with curcumin level (group 1: 207.9 ± 39.84 mg/dL; group 2; 159.7 ± 48.43 mg/dL, p < 0.05), with a decrease in triglycerides levels (group 1: 141.6 ± 9.57; group 2: 97.5 ± 8.8 mg/dL, p < 0.01). This study showed that curcumin has a synergistic effect with metformin in the improvement of insulin resistance and lipid profile in patients with PCOS. Therefore, the combined use of metformin and curcumin may have therapeutic utility in patients with PCOS.

RESUMO

Cutaneous leishmaniosis (CL) is one of the important neglected tropical diseases caused by Leishmania spp. such as L. major, L. tropica in the Old World. In recent years, some reports of treatment failure in patients with CL have been reported worldwide. Therefore, in this study, we assessed LmHSP 83, LmTRYR, and LmTRYP gene expressions in treatment failure clinical isolates of L. major. After sampling from the cutaneous lesions, DNA was extracted and then genera verification and species identification was done using ITS1-PCR-RFLP method. A part of each sample was used in order to RNA extraction and cDNA synthesized. LmHSP 83, LmTRYR, and LmTRYP gene expressions were assessed using SYBR Green real-time PCR. The treatment failure clinical isolates had the mean expression of 5.55±1.67, 247.024±23.54, and 1.204±2.14 for LmHSP 83, LmTRYR, and LmTRYP , respectively less than the same genes in treatment response isolates (P=0.001). This study recommended the other mechanisms may involve in response to treatment in treatment failure clinical isolates of L. major.

RESUMO

BACKGROUND: Antibiotic resistance is associated with longer hospitalizations, higher treatment costs, and increased morbidity and mortality rates. PURPOSE: This study aimed to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in Iranian children. METHODS: International databases, including Web of Science, PubMed, Embase, and Scopus, and Iranian databases, including Scientific Information Database (www.sid.ir), Magiran, and Iranian Database for Medical Literature (idml.research.ac.ir), were systematically searched for articles published between January 2000 and August 2019. Sources of heterogeneity were determined using subgroup analysis and meta-regression. RESULTS: Overall, 343 studies were identified; of them, 20 were included in the meta-analysis to estimate the pooled prevalence. The pooled prevalence of MRSA was 42% (95% confidence interval [CI], 29-55) among culture-positive cases of S. aureus, 51% (95% CI, 39-62) in hospitalized children, and 14% (95% CI, 0.05-27) in healthy children. CONCLUSION: The overall pooled prevalence of MRSA in children was 42%. Appropriate infection control measures and effective antibiotic therapy are needed.

RESUMO

BACKGROUND: Few studies have been conducted regarding the comparison of the efficacy of methadone and tincture of opium (TOP) in controlling agitation induced by withdrawal syndrome. Therefore, the current randomized trial study is carried out with the aim to evaluate comparisons on the efficacy of methadone and TOP in controlling agitation caused by withdrawal syndrome in opium addicted patients in the intensive care units (ICUs). METHODS: This clinical trial study was conducted on 60 patients admitted to ICU of Shahid Bahonar Hospital, Kerman, Iran. After classification of the patients into two groups, the first and second groups consumed methadone syrup (5 mg/ml) and TOP (10 mg/ml), respectively. Agitation in these patients was assessed through the Richmond Agitation-Sedation Scale (RASS). Vital signs were also assessed. Paired sample t-test and independent t-test were used for data analysis. FINDINGS: In the current study, the administered dose of methadone and TOP was 36.17 ± 26.99 and 112.67 ± 102.74 mg, respectively (P < 0.010). Methadone administration led to a significant decrease of the patients' vital signs, including systolic blood pressure, heart rate, respiratory rate, and Glasgow Coma Scale (GCS) (P < 0.05). Though TOP administration decreased systolic blood pressure and GCS significantly (P < 0.05), it had no effect on patients' diastolic blood pressure, body temperature, heart rate, and respiratory rate (P > 0.05). In total, no significant difference was detected between two groups regarding vital signs (P > 0.05). However, a significant difference was seen between methadone and TOP groups in terms of RASS score (P < 0.01). CONCLUSION: According to the results of the current study, lower dose of methadone, compared to TOP, could control agitation caused by opium withdrawal symptoms.

RESUMO

With continuous development of therapeutic options for atherosclerosis, image-based biomarkers sensitive to the effect of new interventions are required to be developed for cost-effective clinical evaluation. Although 3D ultrasound measurement of total plaque volume (TPV) showed the efficacy of high-dose statin, more sensitive biomarkers are needed to establish the efficacy of dietary supplements expected to confer a smaller beneficial effect. This study involved 171 subjects who participated in a one-year placebo-controlled trial evaluating the effect of pomegranate. A framework involving a feature selection technique known as discriminative feature selection (DFS) and a semi-supervised graph-based regression (SSGBR) technique was proposed for sensitive detection of plaque textural changes over the trial. 376 textual features of plaques were extracted from 3D ultrasound images acquired at baseline and a follow-up session. A scalar biomarker for each subject were generated by SSGBR based on prominent textural features selected by DFS. The ability of this biomarker for discriminating pomegranate from placebo subjects was quantified by the p-values obtained in Mann-Whitney U test. The discriminative power of SSGBR was compared with global and local dimensionality reduction techniques, including linear discriminant analysis (LDA), maximum margin criterion (MMC) and Laplacian Eigenmap (LE). Only SSGBR (p=4.12×10-6) and normalized LE (p=0.002) detected a difference between the two groups at the 5% significance level. As compared with ΔTPV, SSGBR reduced the sample size required to establish a significant difference by a factor of 60. The application of this framework will substantially reduce the cost incurred in clinical trials.

RESUMO

BACKGROUND: Radiculopathy due to lumbar or cervical disc disease is the most common chronic neuropathic pain in adults. The aim of present study was evaluation of low dose of sodium valproate (VPA) on radicular pain and determining VPA pharmacokinetics. MATERIALS AND METHODS: In this double blind randomized placebo control clinical study, 80 patients with established lumbar or cervical radicular pain, have been randomly allocated into two study groups: 40 have received sodium valproate 200 mg/day and Celecoxib 100 mg/day and acetaminophen 500 mg PRN as rescue medication, and second group has received placebo, Celecoxib and acetaminophen. Quantitative assessment of pain was done by visual analogue scale (VAS) prior to perform the intervention and after ten days (treatment duration). Blood sample has been taken for determining mean through concentration after five half-lives. Evaluation of plasma concentration of VPA and that of efficacy on pain score relationship by comparing VAS before and after the therapy was done. RESULTS: Group A and B have demonstrated significant alleviation in mean VAS score; -21.97 ± 25.41, -14.39 ± 23.03 respectively (P < 0.001). The mean plasma concentration of VPA in group A was: 26.9 ± 13.5 mg/L. Moreover, no significant correlation was seen between pain score with age, gender, and weight (p > 0.05). CONCLUSION: Low dose of sodium valproate especially together with NSAIDs demonstrated good efficacy in lumbar and cervical radicular pain management.

RESUMO

BACKGROUND AND OBJECTIVE: Dietary supplements are expected to confer a smaller beneficial effect than medical treatments. Therefore, there is a need to develop cost-effective biomarkers that can demonstrate the efficacy of such supplements for carotid atherosclerosis. The aim of this study is to develop such a biomarker based on the changes of 376 plaque textural features measured from 3D ultrasound images. METHODS: Since the number of features (376) was greater than the number of subjects (171) in this study, principal component analysis (PCA) was applied to reduce the dimensionality of feature vectors. To generate a scalar biomarker for each subject, elements in the reduced feature vectors produced by PCA were weighted using locality preserving projections (LPP) to capture essential patterns exhibited locally in the feature space. 96 subjects treated by pomegranate juice and tablets, and 75 subjects receiving placebo-matching juice and tablets were evaluated in this study. The discriminative power of the proposed biomarker was evaluated and compared with existing biomarkers using t-tests. As the cost of a clinical trial is directly related to the number of subjects enrolled, the cost-effectiveness of the proposed biomarker was evaluated by sample size estimation. RESULTS: The proposed biomarker was more able to discriminate plaque changes exhibited by the pomegranate and placebo groups than total plaque volume (TPV) according to the result of t-tests (TPV: p=0.34, Proposed biomarker: p=1.5×10-5). The sample size required by the new biomarker to detect a significant effect was 20 times smaller than that required by TPV. CONCLUSION: With the increase in cost-effectiveness afforded by the proposed biomarker, more proof-of-principle studies for novel treatment options could be performed.

RESUMO

Recently, carbon dots (CDs) have attracted great attention due to their superior properties, such as biocompatibility, fluorescence, high quantum yield, and uniform distribution. These characteristics make CDs interesting for bioimaging, therapeutic delivery, optogenetics, and theranostics. Photoluminescence (PL) properties enable CDs to act as imaging-trackable gene nanocarriers, while cationic CDs with high transfection efficiency have been applied for plasmid DNA and siRNA delivery. In this review, we have highlighted the precursors, structure and properties of positively charged CDs to demonstrate the various applications of these materials for nucleic acid delivery. Additionally, the potential of CDs as trackable gene delivery systems has been discussed. Although there are several reports on cellular and animal approaches to investigating the potential clinical applications of these nanomaterials, further systematic multidisciplinary approaches are required to examine the pharmacokinetic and biodistribution patterns of CDs for potential clinical applications.

RESUMO

OBJECTIVE: Most patients admitted to Intensive Care Units (ICU) have problems in using oral medication or ingesting solid forms of drugs. Selecting the most suitable dosage form in such patients is a challenge. The current study was conducted to assess the frequency and types of errors of oral medication administration in patients with enteral feeding tubes or suffering swallowing problems. METHODS: A cross-sectional study was performed in the ICU of Shahid Sadoughi Hospital, Yazd, Iran. Patients were assessed for the incidence and types of medication errors occurring in the process of preparation and administration of oral medicines. FINDINGS: Ninety-four patients were involved in this study and 10,250 administrations were observed. Totally, 4753 errors occurred among the studied patients. The most commonly used drugs were pantoprazole tablet, piracetam syrup, and losartan tablet. A total of 128 different types of drugs and nine different oral pharmaceutical preparations were prescribed for the patients. Forty-one (35.34%) out of 116 different solid drugs (except effervescent tablets and powders) could be substituted by liquid or injectable forms. The most common error was the wrong time of administration. Errors of wrong dose preparation and administration accounted for 24.04% and 25.31% of all errors, respectively. CONCLUSION: In this study, at least three-fourth of the patients experienced medication errors. The occurrence of these errors can greatly impair the quality of the patients' pharmacotherapy, and more attention should be paid to this issue.

RESUMO

BACKGROUND & OBJECTIVES: The mechanism of antimony resistance in Leishmania has been studied extensively, in connection with decreased influx and/or increased eflux of the drug. Aquaporin 1 (AQP1) protein has been shown to mediate the uptake of trivalent antimony. This study was aimed to find the expression level of AQP1 gene in resistant versus non-resistant clinical isolates of Leishmania major in Iranian patients. METHODS: Clinical isolates were obtained from 16 considered patients referred to Navab Safavi Clinical Center, Isfahan, Iran from October 2014 to December 2015. After diagnosis of cutaneous leishmaniasis using microscopic observation, biopsy was performed from lesion(s) of each patient and stored inside RNAlater solution at -20΀C. Written informed consent was obtained from all the patients to participate in the study before recording their information and sampling based on Helsinki declaration. Each patient was treated with Glucantime and followed for three months. All sensitive and resistance isolates were considered and compared with AQP1 gene expression using real time PCR that was analyzed with delta-delta Ct. RESULTS: Out of 16 clinical isolates, four patients were resistant and 12 were non-resistant. The AQP1 gene expression in resistant isolates was significantly higher than the one in response failure isolates (p = 0.001). INTERPRETATION & CONCLUSION: The significant over expression (0.5 fold) of AQP1 gene in resistant versus non- resistant isolates suggests different mechanism of drug resistance such as mutations. Mutations may change the physiological function of the Aquaporin 1 protein that might affect its expression level.

RESUMO

BACKGROUND: Insulin resistance and hyperinsulinemia may play a role in pathogenesis of PCOS. One of the common therapeutic methods is using insulin-sensitizing drugs such as metformin and thiazolidinediones. OBJECTIVE: The purpose was to determine the effect of metformin and pioglitazone on clinical, hormonal and metabolic parameters in women with PCOS. MATERIALS AND METHODS: Eighty four women randomly received one of the following for 3 months: metformin (n=28) (500 mg three times a day), pioglitazone (30 mg daily) (n=28) and combination of both metformin and pioglitazone (n=28) (30 mg/day pioglitazone plus 500 mg metformin three times a day). Hormonal profile, fasting serum insulin, body weight, body mass index, menstrual status and waist to hip ratio were evaluated before and after treatment. RESULTS: Metformin and pioglitazone and combination therapy induced favorable changes in fasting serum insulin, HOMA-IR index, QUICKI, fasting glucose to insulin ratio in women with PCOS. Body weight, BMI, and waist to hip ratio increased significantly after treatment with pioglitazone but the data were similar after administration of metformin or combination therapy. Total testosterone level decreased significantly only after treatment with metformin. After 3 months in patients who received pioglitazone or combination therapy, menstrual cycles became regular in 71.4% and 73.9% respectively. While menstrual improvement happened only in 36.4% of the patients treated with metformin. CONCLUSION: These findings suggest that insulin-sensitizing drugs induce beneficial effect in insulin resistance and menstrual cyclicity but only metformin ameliorated hyperandrogenemia in women with PCOS. Treatment with combination of metformin and pioglitazone did not show more benefit than monotherapy with each drug alone.

RESUMO

Nearly 15% to 25% of patients in general hospitals have a catheter at some time during their stay. Up to 97% of nosocomial urinary tract infections (UTIs) are related to catheter. The type of bacteremia is usually polymicrobial which makes the treatment more difficult. Previous studies showed an increase in mortality from bacteremia in these patients. The aim of the present study was to compare the prevalence of UTIs among patients with and without catheter, and to detect the type of bacteriuria and antibacterial resistance pattern. In this cross sectional study, samples were taken between Jan 2011 and July 2011. 678 hospitalized patients in different wards of Afzalipour hospital, Kerman- Iran, were enrolled in the study. E-test was applied to detect the pattern of resistance to gentamicin, nitrofurantoin, ciprofloxacin, ceftriaxon and co-trimoxazole. Results showed positive culture samples in 86% of female patients. Escherichia coli, Candida and Staphylococcus aureus were detected in 72, 20 and 7 percent of the positive cultures, respectively. 52.3% of detected E.coli was sensitive to gentamicin , 62% to ceftriaxone, 71.4% to ciprofloxacin, and 91.9% were sensitive to nitrofurantoin. Therefore, the most sensitive antibiotics in UTIs were ciprofloxacin and ceftriaxone. Unfortunately, the rate of antibacterial drug resistance was high in comparison with developed countries. Wise selection of antibiotics at hospitals and increasing the knowledge of patients to prevent self use of antibiotics can reduce antimicrobial resistance.

AIM: The aim was to evaluate the level of interleukin 8 (IL-8), transforming growth factor ß1 (TGF ß1) and Nitric oxide (NO) in diffuse axonal injury (DAI) and its association to the outcome and clinical status. MATERIAL AND METHODS: This cross-sectional study was conducted on 20 patients with DAI and 20 patients with multiple traumas without head injury and 20 healthy subjects as controls. Blood levels of IL-8, TGF ß1 and nitric oxide in the 1st, 2nd, 3rd and 7th days of injury were measured. Glasgow coma scale (GCS) of patients was recorded. The patients' outcome was evaluated by Glasgow Outcome Scale (GOS). RESULTS: The level of TGF ß1 was increasing during the admission and had the maximum level at the 7th day. In the DAI group, there was significant correlation between GOS score and serum IL-8 at 7th day of admission (r=-0.68, p= 0.002). In this group the GCS was found to be significantly correlated with the IL-8 concentration at 7th day of admission (p= 0.026, r=-0.55). CONCLUSION: IL-8 has negative correlation with GCS and GOS. TGF ß1 could protect the brain from cytotoxics, hypoxia and acidosis so its level comes down in brain injuries as a result of its overuse.

RESUMO

INTRODUCTION: This study aimed to investigate the effectiveness of low-dose daclizumab for prevention of acute kidney allograft rejection and to evaluate differences between men and women receiving living donor transplants. MATERIALS AND METHODS: This randomized controlled trial was performed on 120 living donor kidney transplant recipients. Participants in the case group received a low dose of daclizumab (1 mg/kg) before and 14 days after transplantation in addition to their standard immunosuppressant regimen. Participants in the control group received the standard treatment protocol only. Acute rejection episodes and graft survival were compared between the two groups. Additionally, graft survival of women and men was compared separately between the two groups. RESULTS: Acute rejection was significantly less frequent in the daclizumab group than in the controls (6.7% versus 18.3%; P = .048). The 6-month survival rates were 95% (95% CI, 92% to 98%) in the daclizumab group and 85% (95% CI, 81% to 89%) in the control group (P = .03). The 6-month graft survival rates of the women were 97% (95% CI, 95% to 99%) in the daclizumab group and 74% (95% CI, 65% to 83%) in the control group (P = .02). However, the difference in graft survival rates was not significant among the men. CONCLUSIONS: The use of induction therapy with two doses of daclizumab reduces the incidence of acute rejection and improves graft survival of living donor kidney transplant recipients. This study shows that these effects are prominent among the female recipients.
