RESUMO

BACKGROUND: An increasing number of coronavirus disease 2019 (COVID-19) related autoimmune hepatitis (AIH) and autoimmune liver disease (AILD) has been already described so far in the last three years. This rise has set up some diagnostic and therapeutic concerns, although steroid therapy has mostly been efficient, avoiding main significant side effects. CASE REPORT: We report the case of a 52-year-old subject displaying liver function impairment at the laboratory tests while positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) swab. Needle liver biopsy showed severe portal inflammation, interface hepatitis, lobular inflammation, abundant plasma cells, bridging necrosis, endothelialitis, bile duct vanishing disease, and ductular reaction. The diagnosis of autoimmune liver disease (AILD) was performed. After a month of steroid and ursodeoxycholic acid medications, liver function fully recovered. Azathioprine was introduced, and steroids were gradually reduced. CONCLUSIONS: Probably triggered by the SARS-CoV-2-induced cytokine storm, the association between COVID-19 and autoimmune-related inflammatory injury may display a particular paradigm of AILD pathogenesis.

RESUMO

PURPOSE: It is well known that interferon-α (IFN-α), used for long time as the main therapy for HCV-related disease, induces thyroid alterations, but the impact of the new direct-acting antivirals (DAAs) on thyroid is not established. Aim of this prospective study was to evaluate if DAAs therapy may induce thyroid alterations. METHODS: A total of 113 HCV patients, subdivided at the time of the enrollment in naïve group (n = 64) and in IFN-α group (n = 49) previously treated with pegylated interferon-α and ribavirin, were evaluated for thyroid function and autoimmunity before and after 20-32 weeks of DAAs. RESULTS: Before starting DAAs, a total of 8/113 (7.1%) patients showed Hashimoto's thyroiditis (HT) all belonging to IFN-α group (8/49, 16.3%), while no HT cases were found in the naïve group. Overall, 7/113 (6.2%) patients were hypothyroid: 3/64 (4.7%) belonging to naïve group and 4/49 (8.2%) to IFN-α group. Furthermore, a total of 8/113 patients (7.1%) showed subclinical hyperthyroidism: 2/64 (3.1%) were from naïve group and 6/49 (12.2%) from IFN-α group. Interestingly, after DAAs therapy, no new cases of HT, hypothyroidism and hyperthyroidism was found in all series, while 6/11 (54.5%) patients with non-autoimmune subclinical thyroid dysfunction became euthyroid. Finally, the only association between viral genotypes and thyroid alterations was genotype 1 and hypothyroidism. CONCLUSIONS: This study supports evidence that DAAs have a limited or missing influence on thyroid in patients with HCV-related diseases. Moreover, it provides preliminary evidence that subclinical non-autoimmune thyroid dysfunction may improve after HCV infection resolution obtained by DAAs.

RESUMO

Congenital toxoplasmosis (CT) is a zoonosis resulting from the fetal transmission of the obligate intracellular parasite, T. gondii, transplacentally in pregnant women usually in the first trimester of pregnancy. This research consisted in the review of indexed articles made in the Ecuador in the period between the years 2012 and 2017 with prevalence studies of the aforementioned pathology. The purpose of this collection was to determine the current situation of this disease in the Ecuadorian territory and, in addition, to recognize the risk factors involved, affected age groups, signs and symptoms, diagnosis and prevalence of the infection. Among the risk factors were the consumption of raw or undercooked meat, contact with feces of young cats and climatic conditions that stimulate the spread of oocysts, among others. Most affected ages by this disease fluctuate between 20 and 30 years. In 90% of the cases, the disease is asymptomatic or it may present adenopathies, maculo papular erythema, hepatosplenomegaly and other general signs such as fever, malaise, headache and myalgias. According to studies conducted with specific populations, it was established that the causative agent remains latent in first-trimester pregnant women from the provinces of Pichincha (71.4% of 140 pregnant women), Guayas (73% of 5683) and El Oro (16% of 250). The results of this research evidenced missing information in Ecuador, finding few and isolated studies regarding to this pathology. Therefore, it is concluded that an updated research should be conducted in order to elucidate the true epidemiological situation of congenital toxoplasmosis in Ecuador.

RESUMO

BACKGROUND & AIMS: There is convincing clinical evidence to suggest that flavanol-containing foods/beverages are capable of inducing improvements in human vascular function. However, whilst (-)-epicatechin has been tested for efficacy, a full dose-dependency has yet to be established, particularly at doses below 1 mg/kg BW. The current study examined the dose-dependent effects of (-)-epicatechin on human vascular function with concurrent measurement of plasma (-)-epicatechin metabolites and levels of circulating nitrite and nitrate species, NOx. METHODS: An acute, double-blind, placebo-controlled, crossover intervention trial was conducted in 20 healthy males with 4 treatment arms: water-based (-)-epicatechin (0.1, 0.5 and 1.0 mg/kg BW) and a water only as control. Vascular function was assessed by flow-mediated dilatation (FMD) measured at the brachial artery, laser Doppler imaging with iontophoresis (LDI) at the subcutaneous capillaries of the forearm (response to Ach and SNP) and peripheral blood pressure (BP) at baseline, 1, 2, 4 and 6 h post-intervention. Plasma analysis of epicatechin metabolites was conducted by LC-MS and circulating plasma of nitrite and nitrate species were performed using an HPLC-based system (ENO-30). RESULTS: Significant increases in % FMD were found to occur at 1 and 2 h following intake of 1 mg/kg BW, and at 2 h for the 0.5 mg/kg BW intake. There were no significant changes in LDI or BP at any time-points or intake levels. Increases in FMD over the 6 h timeframe were closely paralleled by the appearance of total plasma (-)-epicatechin metabolites. Non-significant changes in circulating NOx was observed. CONCLUSIONS: Our data add further evidence that (-)-epicatechin is a causal vasoactive molecule within flavanol-containing foods/beverages. In addition, we show for the first time that intake levels as low as 0.5 mg/kg BW are capable of inducing acute improvements in vascular function (FMD) in healthy volunteers.

RESUMO

OBJECTIVES: Identifying factors predictive of long-term morbidity should improve clinical planning limiting disability and mortality associated with bipolar disorder (BD). METHODS: We analyzed factors associated with total, depressive and mania-related long-term morbidity and their ratio D/M, as %-time ill between a first-lifetime major affective episode and last follow-up of 207 BD subjects. Bivariate comparisons were followed by multivariable linear regression modeling. RESULTS: Total % of months ill during follow-up was greater in 96 BD-II (40.2%) than 111 BD-I subjects (28.4%; P=0.001). Time in depression averaged 26.1% in BD-II and 14.3% in BD-I, whereas mania-related morbidity was similar in both, averaging 13.9%. Their ratio D/M was 3.7-fold greater in BD-II than BD-I (5.74 vs. 1.96; P<0.0001). Predictive factors independently associated with total %-time ill were: [a] BD-II diagnosis, [b] longer prodrome from antecedents to first affective episode, and [c] any psychiatric comorbidity. Associated with %-time depressed were: [a] BD-II diagnosis, [b] any antecedent psychiatric syndrome, [c] psychiatric comorbidity, and [d] agitated/psychotic depressive first affective episode. Associated with %-time in mania-like illness were: [a] fewer years ill and [b] (hypo)manic first affective episode. The long-term D/M morbidity ratio was associated with: [a] anxious temperament, [b] depressive first episode, and [c] BD-II diagnosis. CONCLUSIONS: Long-term depressive greatly exceeded mania-like morbidity in BD patients. BD-II subjects spent 42% more time ill overall, with a 3.7-times greater D/M morbidity ratio, than BD-I. More time depressed was predicted by agitated/psychotic initial depressive episodes, psychiatric comorbidity, and BD-II diagnosis. Longer prodrome and any antecedent psychiatric syndrome were respectively associated with total and depressive morbidity.

RESUMO

BACKGROUND: Menarche age has been associated inconsistently with the occurrence, timing or severity of major depressive disorder (MDD), but rarely studied in women with bipolar (BDs) or anxiety disorders. METHODS: We investigated women patients at a Sardinian mood disorder center for associations of age at menarche with age at illness onset for major affective or anxiety disorders, year of birth, and other selected factors, using bivariate comparisons and multivariate regression modeling. RESULTS: Among women (n=1139) with DSM-IV MDD (n=557), BD-I (n=223), BD-II (n=178), or anxiety disorders (n=181), born in 1904-1998, of mean age 42.9 years, menarche age averaged 12.8 [CI: 12.7-12.9] years. Illness onset age averaged 30.9 [30.1-31.8] years, ranking: BD-I, 25.8; anxiety disorders, 28.0; BD-II, 30.3; MDD, 34.1 years. Menarche age declined secularly over birth years, and was associated with younger illness-onset, having no or fewer siblings, more psychiatrically ill first-degree relatives, living in rural environments, being suicidal, substance abuse, and being unemployed. Earlier menarche and earlier illness-onset were significantly associated for onset age groups of ≤ 20, 20-39, and > 40 years. Menarche age versus diagnosis ranked: BD-II

RESUMO

INTRODUCTION: Honey as a topical treatment for infected wounds dates back to ancient times. However, few studies have been reported concerning the medical properties of Italian honey. In this study, the microbial contamination, the antimicrobial activity and the antibiotic residues of 6 different varieties of Piedmont honeys were evaluated. The antimicrobial activity of honeys was tested by agar well diffusion method and 1 honey for each variety has been selected and tested by broth micro-dilution test to determine Minimum Inhibitory Concentrations (MICs) and evaluated by Minimum Bactericidal Concentrations (MBCs). The honeys with a high level of antibacterial activity were analyzed for the presence of tetracyclines, sulfonamides and macrolide residues. The agar well diffusion method showed the greatest antimicrobial activity for honeydew, chestnut and lime tree honeys. The MICs and MBCs identified the close similarity to the medical manuka honey of honeydew, polyfloral and chestnut honey. The levels of antibiotic residues on these honeys were below the limit of quantification. Based on our results the Italian variety of honeydew showed the best antimicrobial activity and can be considered for the treatment of infected wounds in animals.


INTRODUCTION: L'utilisation du miel pour le traitement des plaies infectées remonte à loin dans l'antiquité. Dans le présent travail, on étudie les contaminations microbiennes, l'activité antimicrobienne et les résidus d'antibiotiques dans 6 sortes de miels différentes provenant du Piémont. L'activité antimicrobienne a été mesurée au moyen d'une méthode de diffusion sur gel d'agar et un échantillon de chaque sorte de miel a été examiné quant à sa concentration minimale inhibitrice (CMI) et sa concentration minimale bactéricide (CMB) au moyen d'un test de micro-dilution. Les échantillons présentant une haute activité antibactérienne ont été analysés quant à la présence de tétracycline, de sulfamidés et de macrolides. Au test de diffusion sur agar, le miel de miellat ainsi que ceux de châtaignier et de tilleul ont démontré la plus grande activité antimicrobienne. Les CIM et CBM permettent de reconnaitre une grande similitude entre les miels de miellat, de nectar et de tilleul avec le miel de Manuka utilisé à des fins thérapeutiques. Les résidus d'antibiotiques de ces échantillons se situaient en dessous des limites de détection. Sur la base de ces constatations, les divers miels de miellat italiens présentent la plus grande activité antimicrobienne et peuvent être utilisés pour le traitement de plaies infectées chez les animaux.

RESUMO

Connective tissue diseases (CTDs) are a heterogeneous group of idiopathic inflammatory diseases involving various organs. A thoracic involvement is frequent, and chest-CT represents the imaging technique of reference in its assessment. Pulmonary abnormalities related to CTDs are various; although several disease-specific aspects have been described, the two most clinically relevant complications are represented by interstitial lung disease and pulmonary arterial hypertension. The early identification of a thoracic involvement, with the adoption of specific therapies, can significantly change patient's prognosis. The aim of this article is to review the most common typical and atypical CT features of thoracic involvement occurring in CT, especially focusing on interstitial lung disease.

RESUMO

BACKGROUND: Anal fissure (AF) is a common cause of anal pain with a tendency not to heal spontaneously because of ischemia of the anoderm caused by sphincter spasm. Lateral internal sphincterotomy, while very effective, can cause fecal incontinence and chemical sphincterotomy by application of cream may have discouraging side effects and/or low efficacy. The aim of this prospective multicenter study was to evaluate the safety and effectiveness of a new medical treatment based on Emulgel cream, with emollient, soothing and protective agents, on AF healing. METHODS: Consecutive patients with AF treated in nine coloproctology units during 6 months entered the study on topical treatment with Levorag(®) Emulgel (THD S.p.A Correggio (RE), Italy). Before treatment, they had a proctologic examination and pain was measured using a visual analog scale. THD Levorag(®) Emulgel was applied every 12 h for 40 days. Monitoring was scheduled at 10, 20 and 40 days. At time 0 and at the end of treatment, patients underwent anorectal manometry, if possible. RESULTS: Two hundred eighty-four AF patients were recruited (171 acute fissures). Complete healing was achieved in 47.9 % of the cases, an improvement in 31.0 % (global efficacy 78.9 %). In patients with acute fissure, the rate of efficacy was 89.4 % (complete healing: 64.3 %, improvement: 25.1 %), in those with chronic fissure the rate of efficacy was 62.8 % (complete healing: 23 %, improvement: 39.8 %), p < 0.001. Pain and resting anal pressure decreased significantly after treatment. CONCLUSIONS: Treatment with THD Levorag(®) Emulgel proved to be effective for the reepithelization of AF and the reduction of pain in the short term in about 80 % of patients.

RESUMO

Systemic primary vasculitides are rare idiopathic diseases causing an inflammatory injury to the vessel walls. A pulmonary involvement is frequent, and chest-CT is the imaging technique of reference in its assessment. An extremely wide variety of parenchymal, vascular and airways abnormalities, has been described and diagnosis can be challenging: knowledge of clinical data and a close cooperation with the referring physician is often crucial. The aim of this work is to describe the most common typical and atypical CT features of pulmonary vasculitis and their possible changes over time and therapy, focusing on the differential diagnosis with other inflammatory/infectious or neoplastic diseases.

RESUMO

A new project was recently initiated for the realization of the "Land Unit and Soil Capability Map of Sardinia" at a scale of 1:50,000 to support land use planning. In this study, we outline the general structure of the project and the methods used in the activities that have been thus far conducted. A GIS approach was used. We used the soil-landscape paradigm for the prediction of soil classes and their spatial distribution or the prediction of soil properties based on landscape features. The work is divided into two main phases. In the first phase, the available digital data on land cover, geology and topography were processed and classified according to their influence on weathering processes and soil properties. The methods used in the interpretation are based on consolidated and generalized knowledge about the influence of geology, topography and land cover on soil properties. The existing soil data (areal and point data) were collected, reviewed, validated and standardized according to international and national guidelines. Point data considered to be usable were input into a specific database created for the project. Using expert interpretation, all digital data were merged to produce a first draft of the Land Unit Map. During the second phase, this map will be implemented with the existing soil data and verified in the field if also needed with new soil data collection, and the final Land Unit Map will be produced. The Land Unit and Soil Capability Map will be produced by classifying the land units using a reference matching table of land capability classes created for this project.

RESUMO

OBJECTIVE: To determine whether CT-perfusion (CT-p) can be used to evaluate the effects of chemotherapy and anti-angiogenic treatment in patients with non-small-cell lung carcinoma (NSCLC) and whether CT-p and standard therapeutic response assessment (RECIST) data obtained before and after therapy correlate. METHODS: 55 patients with unresectable NSCLC underwent CT-p before the beginning of therapy and 50 of them repeated CT-p 90 days after it. Therapeutic protocol included platinum-based doublets plus bevacizumab for non-squamous carcinoma and platinum-based doublets for squamous carcinoma. RECIST measurements and calculations of blood flow (BF), blood volume (BV), time to peak (TTP) and permeability surface (PS) were performed, and baseline and post-treatment measurements were tested for statistically significant differences. Baseline and follow-up perfusion parameters were also compared based on histopathological subclassification (2004 World Health Organization Classification of Tumours) and therapy response assessed by RECIST. RESULTS: Tumour histology was consistent with large cell carcinoma in 14/50 (28%) cases, adenocarcinoma in 22/50 (44%) cases and squamous cell carcinoma in the remaining 14/50 (28%) cases. BF and PS differences for all tumours between baseline and post-therapy measurements were significant (p=0.001); no significant changes were found for BV (p=0.3) and TTP (p=0.1). The highest increase of BV was demonstrated in adenocarcinoma (5.2±34.1%), whereas the highest increase of TTP was shown in large cell carcinoma (6.9±22.4%), and the highest decrease of PS was shown in squamous cell carcinoma (-21.5±18.5%). A significant difference between the three histological subtypes was demonstrated only for BV (p<0.007). On the basis of RECIST criteria, 8 (16%) patients were classified as partial response (PR), 2 (4%) as progressive disease (PD) and the remaining 40 (80%) as stable disease (SD). Among PR, a decrease of both BF (18±9.6%) and BV (12.6±9.2%) were observed; TTP increased in 3 (37.5%) cases, and PS decreased in 6 (75%) cases. SD patients showed an increase of BF, BV, TTP and PS in 6 (15%), 21 (52.5%), 23 (57.5%) and 2 (5%) cases, respectively. PD patients demonstrated an increase of BF (26±0.2%), BV (2.7±0.1%) and TTP (3.1±0.8%) while only PS decreased (23±0.2%). CONCLUSION: CT-p can adequately evaluate therapy-induced alterations in NSCLC, and perfusion parameters correlate with therapy response assessment performed with RECIST criteria. ADVANCES IN KNOWLEDGE: Evaluating perfusional parameters, CT-p can demonstrate therapy-induced changes in patients with different types of lung cancer and identify response to treatment with excellent agreement to RECIST measurements.

RESUMO

PURPOSE: The authors evaluated the role of magnetic resonance (MR) imaging of the chest in comparison with chest X-ray in the follow-up of pulmonary abnormalities detected by computed tomography (CT) in paediatric patients with middle lobe syndrome. MATERIALS AND METHODS: Seventeen patients with middle lobe syndrome (mean age 6.2 years) underwent chest CT at the time of diagnosis (100 kV, CARE dose with quality reference of 70 mAs; collimation 24×1.2 mm; rotation time 0.33 s; scan time 5 s); at follow-up after a mean of 15.3 months, all patients were evaluated with chest MR imaging with a respiratory-triggered T2-weighted BLADE sequence (TR 2,000; TE 27 ms; FOV 400 mm; flip angle 150°; slice thickness 5 mm) and chest X-ray. Images from each modality were assessed for the presence of pulmonary consolidations, bronchiectases, bronchial wall thickening and mucous plugging. Hilar and mediastinal lymphadenopathies were assessed on CT and MR images. RESULTS: Baseline CT detected consolidations in 100% of patients, bronchiectases in 35%, bronchial wall thickening in 53% and mucous plugging in 35%. MR imaging and chest X-ray identified consolidations in 65% and 35%, bronchiectases in 35% and 29%, bronchial wall thickening in 59% and 6% and mucous plugging in 25% and 0%, respectively. Lymphadenopathy was seen in 64% of patients at CT and in 47% at MR imaging. CONCLUSIONS: Patients with middle lobe syndrome show a wide range of parenchymal and bronchial abnormalities at diagnosis. Compared with MR imaging, chest X-ray seems to underestimate these changes. Chest MR imaging might represent a feasible and radiation-free option for an overall assessment of the lung in the follow-up of patients with middle lobe syndrome.

RESUMO

Hypohidrotic ectodermal dysplasia (HED) was first described in 1848 by Thurnam. HED belongs to ectodermal dysplasias (EDs), which are developmental impairments of ectodermal-derived tissues. X-linked hypohidrotic ectodermal dysplasia (XLHED) is the most common form of the EDs and consists in abnormal development of teeth, hair, and eccrine sweat glands. XLHED is determined by mutations in the ED1 gene, which is responsible for the coding of ectodysplasin-A(EDA-A), a protein that regulates ectodermal appendage formation. In the present study we found both in our proband and in the mother the same missense mutation in exon 9 (c.957 C>A), which resulted in an aminoacid change at position 319 (Ser319Arg). This latter anomaly might alter the charges in the TNF domain of EDA-A, affecting the stability of the protein and therefore the interaction with its receptor. The male propositus presented classical manifestations of HED except for keratoconus (KC) and, to the best of our knowledge, this association has not been previously described. The identification of this new mutation may contribute to evaluating the genotype/phenotype correlations. Finally, this report can give useful information about the genetic basis of KC and HED. Future studies will allow us to understand if a genetic bond exists between them.

RESUMO

The geste antagoniste is a voluntary maneuver that temporarily reduces the severity of dystonic posture or movements. It is a classical feature of focal and particularly cervical dystonia. However, the precise historical aspects of geste antagoniste still remain obscure. The goals of this review were (1) to clarify the origin of the geste antagoniste sign; (2) to identify the factors that led to its diffusion in the international literature; (3) to follow the evolution of that term across the twentieth century. We used medical and neurological French, German and English literature of the late nineteenth and early twentieth centuries, and the PubMed database by entering the terms geste antagoniste, antagonistic gesture and sensory trick. The geste antagoniste sign is a legacy of the Paris Neurological School of the end of the nineteenth century. The term was introduced by Meige and Feindel in their 1902 book on tics, written in the vein of their master, Brissaud, who first described this sign in 1893. The almost immediate translations of this book by Giese into German and Kinnier Wilson into English contributed to the rapid spreading of the term geste antagoniste, which is still in use worldwide today. The term antagonistic gesture is the translation proposed by Kinnier Wilson, which also led to the use of the term geste antagonistique. The geste antagoniste sign has long been considered a solid argument for the psychogenic origins of dystonia until the 1980s when Marsden made strong arguments for its organic nature.

RESUMO

PURPOSE: This study was done to assess the diagnostic potential of dual-source computed tomography (DSCT) in the functional evaluation of lung cancer patients undergoing surgical resection. The CT data were compared with pulmonary perfusion scintigraphy and pulmonary function tests (PFTs). MATERIALS AND METHODS: All patients were evaluated with DSCT, scintigraphy and PFTs. The DSCT scan protocol was as follows: two tubes (80 and 140 kV; Care Dose protocol); 70 cc of contrast material (5 cc/s); 5- to 6-s scan time; 0.6 mm collimation. After the automatic calculation of lung perfusion with DSCT and quantification of air volumes and emphysema with dedicated software applications, the perfusional CT studies were compared with scintigraphy using a visual score for perfusion defects; CT air volumes and emphysema were compared with PFTs. RESULTS: The values of accuracy, sensitivity, specificity and positive (PPV) and negative (NPV) predictive values of DSCT compared with perfusion scintigraphy as the reference standard were: 0.88, 0.84, 0.90, 0.93 and 0.88, respectively. The McNemar test did not identify significant differences either between the two imaging techniques (p=0.07) or between CT and PFTs (p=0.09). CONCLUSIONS: DSCT is a robust and promising technique that provides important and accurate information on lung function.

RESUMO

White matter hyperintensities (WMHs) refer to areas of hyperintense signal on T2- or proton density-weighted brain magnetic resonance imaging. Although WMHs are a common finding in patients with bipolar disorder (BD), particularly with a later disease onset, some studies report a higher frequency of WMHs only in unipolar affective disorders. We reviewed the literature examining examining both the severity and presence of WMHs in late life and particularly in individuals with late-onset BD (LOBD). Studies investigating white matter lesions in LOBD were systematically retrieved and the reference lists of these studies were scanned for additional relevant studies of neuroimaging in LOBD. The majority of neuroimaging studies reported an association between older age and LOBD and the presence of WMHs in LOBD. Also, we found in a small sample of patients preliminary evidence of a significant relationship between older age with late-onset BD and WMHs having a higher prevalence of cardiovascular and cerebrovascular risk factors. In conclusion over 60 years older individuals with LOBD and WMHs might have a type of illness characterized by more neuropathological changes and biologically different compared to non LOBD. This is consistent with the hypothesis of vascular mania. WMHs could be a reliable biological risk marker for late onset mood disorders.

RESUMO

BACKGROUND: In large-scale clinical trials, the proliferation signal inhibitor (PSI) everolimus (EVL) combined with cyclosporine (CsA) and steroids, has been shown to be efficacious among de novo renal transplant recipients. Development of proteinuria has been shown to be an important predictor of renal dysfunction after conversion from CsA to a PSI-based regimen, and a key marker of allograft disease progression. Whether EVL de novo treatment is associated with a similar proteinuric effect is still under investigation. METHODS: We compared the development of proteinuria among a cohort of 24 renal transplant recipients who were prescribed EVL (3 mg/d; n = 12; high-dose group) or 1.5 mg/d (n = 12; standard-dose group), in association with CsA, versus third control cohort of 12 patients who received mycophenolate mofetil (control group). EVL doses were adjusted to achieve trough blood levels of 3-8 ng/mL and 8-12 ng/mL among the standard and high-dose groups, respectively. We assessed renal function and protein excretion over a 2-year observation. RESULTS: The high-dose group showed a trend toward greater proteinuria than the standard-dose on control groups. They showed significantly greater proteinuria from 9 months until 2 years; 0.86 +/- 0.5, 0.5 +/- 0.3, 0.47 +/- 0.2 g/24 h (P = .03 and P = .02, respectively, at 24 months). Mean proteinuria significantly correlated with mean EVL doses (n = .73; P = .0001). Concomitantly, the estimated glomerular filtration rate (eGFR) was significantly lower among patients treated with EVL 3.0 versus 1.5 mg/d (53.7 +/- 24 vs 73.04 +/- 17.6 mL/min; P = .037). Among patients in the standard-dose, the eGFR was consistently higher than the control group (62.6 +/- 29 mL/min). CONCLUSION: EVL/CsA therapy is a safe alternative regimen for de novo renal transplant recipients. Higher EVL doses are correlated with greater increases in proteinuria. The standard EVL dose seems to be useful treatment strategy to prevent acute rejection episodes, with a better renal prognosis in the long term.
