Intra-articular injection of platelet lysate-derived extracellular vesicles recovers from knee osteoarthritis in an in vivo rat model.

Objective: MSCs and Platelet-Rich Plasma are the main focus in the study of new regenerative treatments aimed to reverse Osteoarthritis (OA). However, extracellular vesicles (EVs) present several advantages to cell-based treatments. Thus, the aim of this study was to compare and evaluate the regenerative potential of MSC-derived EVs (cEVs) and platelet-derived EVs (pEVs) in an OA cartilage rat model. Design: OA in vivo model was established through injection of 6 mg MIA in the rat knee joints. After 14 and 21 days, OA knee joints were treated with 1 × 1010 particles of pEVs or cEVs. At day 28, the animals were sacrificed, plasma was collected to quantify CTX-II and knee joints were excised to be evaluated by Cone Beam Computed Tomography (CBCT). After decalcification, histology was used to determine the OARSI score and to visualize collagen and glycosaminoglycan content. Results: pEVs and cEVs samples did not show significant differences per se but they did in terms of regenerative effects on OA knee joints. pEVs-treated knee joints showed better subchondral bone integrity in CT-analysed parameters when compared to cEVs or OA group, showing similar values to the healthy control group. Moreover, OARSI score indicated that pEVs showed a greater OA reversion in knee joints, especially in female rats, and so indicated the analysed histological images. Conclusions: pEVs are proposed as a viable regeneration treatment for OA since they are not only capable of exerting their regenerative potential on osteoarthritic cartilage, but also outperform cEVs in terms of efficacy, particularly in females. Significance statement: Osteoarthritis (OA) is one of the most age-related diseases. It is estimated that 500 million people suffer from OA worldwide, representing the principal cause of chronic disability in adults. In the present study we evaluated the therapeutic effect of extracellular vesicles (EVs) from different sources (platelet lysate and human umbilical cord mesenchymal stromal cells) in an in vivo rat model. Our results demonstrate that platelet-derived EVs (pEVs) induce an OA reversion in knee joints, thus evidencing the therapeutic potential of pEVs as cell-free regenerative agents for OA treatment. The translational potential of this article: Platelet-derived extracellular vesicles (pEVs) offer a promising cell-free therapy option for OA treatment. Their production could be easily standardized and reproduced without extensive platelet harvesting and amplification, thus paving the way for their clinical translation.

Serum Vitamins A and E at Mid-Pregnancy and Their Relationships with Both Maternal and Cord Blood Antioxidant Status and Perinatal Conditions: The NELA Cohort.

INTRODUCTION: Most of the pregnant women do not achieve the recommended dietary intake of vitamins A and E. These vitamins may counteract oxidative stress involved in some adverse perinatal outcomes. We aimed to assess the associations between maternal vitamin A and E at mid-pregnancy with both maternal and fetal outcomes and to identify possible early biomarkers during pregnancy to predict and prevent oxidative stress in the offspring. METHODS: Data on dietary and serum levels of vitamins A and E were collected from 544 pregnant women from the Nutrition in Early Life and Asthma (NELA) study, a prospective mother-child cohort set up in Spain. RESULTS: There were large discrepancies between low dietary vitamin E intake (78% of the mothers) and low serum vitamin E levels (3%) at 24 weeks of gestation. Maternal serum vitamins A and E at mid-pregnancy were associated with higher antioxidant status not only in the mother at this time point (lower hydroperoxides and higher total antioxidant activity [TAA]) but also with the newborn at birth (higher TAA). Gestational diabetes mellitus (GDM) was negatively associated with maternal serum vitamin A (OR: 0.95 CI: 0.91-0.99, p = 0.009) at mid-pregnancy. Nevertheless, we could not detect any association between GDM and oxidative stress parameters. CONCLUSIONS: In conclusion, maternal vitamin A and E serum levels may be used as an early potential biomarker of antioxidant status of the neonate at birth. Control of these vitamins during pregnancy could help avoid morbid conditions in the newborn caused by oxidative stress in GDM pregnancies.

Extracellular Vesicle-Based Hydrogels for Wound Healing Applications.

Hydrogels and extracellular vesicle-based therapies have been proposed as emerging therapeutic assets in wound closure. The combination of these elements has given good results in managing chronic and acute wounds. The intrinsic characteristics of the hydrogels in which the extracellular vesicles (EVs) are loaded allow for overcoming barriers, such as the sustained and controlled release of EVs and the maintenance of the pH for their conservation. In addition, EVs can be obtained from different sources and through several isolation methods. However, some barriers must be overcome to transfer this type of therapy to the clinic, for example, the production of hydrogels containing functional EVs and identifying long-term storage conditions for EVs. The aim of this review is to describe the reported EV-based hydrogel combinations, along with the obtained results, and analyze future perspectives.

Influence of Laboring People's Mobility and Positional Changes on Birth Outcomes in Low-Dose Epidural Analgesia Labor: A Systematic Review with Meta-Analysis.

INTRODUCTION: Freedom of movement has been identified as a key issue for pregnant individuals during the birthing process, even if they opt for epidural analgesia, which has relegated people to more static positions during birth for many years. The aims of this systematic review were to evaluate the influence of mobility and positional changes on perinatal and neonatal outcomes in people in labor with epidural analgesia, describe the range of movement interventions used during the first and second stage of labor, and describe the level of motor blockade among people with low-dose epidural analgesia. METHODS: Bibliographic databases (Web of Science, Cochrane, CINAHL) were consulted from December 2020 to January 2021. The articles selected were clinical trials and observational or analytical studies, the subject of which was mobilization during labor in people with epidural analgesia. The outcome measures were mode of birth, duration of labor, and extrauterine adaptation after birth. A narrative synthesis was used to describe the types of movements interventions employed during the stages of labor and the level of motor blockade among people with low-dose epidural analgesia. RESULTS: Ten articles were selected (8 clinical trials, one cross-sectional study, and one quasiexperimental study), with a total sample of 6086 individuals. A meta-analysis showed nonsignificant results between groups for mode of birth (relative risk [RR], 1.00; 95% CI, 0.87-1.14), duration of labor (RR, 1.64; 95% CI, -34.57 to 37.86), and extrauterine adaptation after birth (RR, 0.86; 95% CI, 0.39-1.93). There was heterogeneity among studies in the type of movement interventions used during the first and second stage of labor. DISCUSSION: Although no clear benefit was observed for mobilization in epidural labor, no detrimental effects were found either, so perinatal care providers should encourage mobilization if the laboring person so desires, throughout the entire childbirth process.

Dietary Patterns in Pregnancy and Biomarkers of Oxidative Stress in Mothers and Offspring: The NELA Birth Cohort.

Background: Although adherence to the Mediterranean and antioxidant-rich diets during pregnancy is suggested to improve maternal-fetal health by reducing oxidative stress, yet there is no study available. Objective: We examined whether maternal dietary patterns in pregnancy impact the biomarkers of oxidative stress in mothers and their offspring. Methods: Study population included 642 mothers and 335 newborns of the "Nutrition in Early Life and Asthma" (NELA) birth cohort. Maternal diet during pregnancy was assessed by a validated food frequency questionnaire and a priori-defined dietary indices (relative Mediterranean Diet [rMED], alternative Mediterranean Diet [aMED], Dietary Approach to Stop Hypertension [DASH], Alternate Healthy Index [AHEI], and AHEI-2010) were calculated. Biomarkers measured were: hydroperoxides, carbonyl groups, and 8-hydroxydeoxyguanosine (8OHdG) determined in maternal blood and newborn cord blood, and urinary maternal and offspring 15-F2t-isoprostane. Multivariate linear regression models were performed. Results: Maternal rMED score was inversely associated with the maternal levels of 8OHdG at mid-pregnancy (beta per 1-point increase = -1.61; 95% CI -2.82, -0.39) and the newborn levels of hydroperoxides (beta per 1-point increase = -4.54; 95% CI -9.32, 0.25). High vs. low maternal rMED score was marginally associated with the decreased levels of 8OHdG in newborns (beta = -9.17; 95% CI -19.9, 1.63; p for trend 0.079). Maternal DASH score tended to be inversely associated with maternal urinary 15-F2t-isoprostane (beta per 1-point increase = -0.69; 95% CI, -1.44, 0.06). High vs. low maternal AHEI score was associated with reduced offspring urinary levels of 15-F2t-isoprostane (beta = -20.2; 95% CI -38.0, -2.46; p for trend 0.026). Conclusion: These results suggest that maternal adherence to healthy dietary patterns during pregnancy may reduce DNA damage and lipid oxidation in mothers and offspring.

Self-Reported DHA Supplementation during Pregnancy and Its Association with Obesity or Gestational Diabetes in Relation to DHA Concentration in Cord and Maternal Plasma: Results from NELA, a Prospective Mother-Offspring Cohort.

Maternal supplementation of docosahexaenoic acid (DHA) during pregnancy has been recommended due to its role in infant development, but its effect on materno-fetal DHA status is not well established. We evaluated the associations between DHA supplementation in pregnant women with obesity or gestational diabetes mellitus (GDM) and maternal and neonatal DHA status. Serum fatty acids (FA) were analyzed in 641 pregnant women (24 weeks of gestation) and in 345 venous and 166 arterial cord blood samples of participants of the NELA cohort. Obese women (n = 47) presented lower DHA in serum than those lean (n = 397) or overweight (n = 116) before pregnancy. Linoleic acid in arterial cord was elevated in obese women, which indicates lower fetal retention. Maternal DHA supplementation (200 mg/d) during pregnancy was associated with enhanced maternal and fetal DHA levels regardless of pre-pregnancy body mass index (BMI), although higher arterial DHA in overweight women indicated an attenuated response. Maternal DHA supplementation was not associated with cord venous DHA in neonates of mothers with GDM. The cord arteriovenous difference was similar for DHA between GDM and controls. In conclusion, maternal DHA supplementation during pregnancy enhanced fetal DHA status regardless of the pre-pregnancy BMI while GDM may reduce the effect of DHA supplementation in newborns.

Air pollution from traffic during pregnancy impairs newborn's cord blood immune cells: The NELA cohort.

BACKGROUND: Hazards of traffic-related air pollution (TRAP) on the developing immune system are poorly understood. We sought to investigate the effects of prenatal exposure to TRAP on cord blood immune cell distributions; and to identify gestational windows of susceptibility. METHODS: In-depth immunophenotyping of cord blood leukocyte and lymphocyte subsets was performed by flow cytometry in 190 newborns embedded in the Nutrition in Early Life and Asthma (NELA) birth cohort (2015-2018). Long-term (whole pregnancy and trimesters) and short-term (15-days before delivery) residential exposures to traffic-related nitrogen dioxide (NO2), particulate matter (PM2.5 and PM10), and ozone (O3) were estimated using dispersion/chemical transport modelling. Associations between TRAP concentrations and cord blood immune cell counts were assessed using multivariate Poisson regression models. RESULTS: Mean number of natural killer (NK) cells decreased 15% in relation to higher NO2 concentrations (≥36.4 µg/m3) during whole pregnancy (incidence relative risk (IRR), 0.85; 95% CI, 0.72, 0.99), with stronger associations in the first trimester. Higher PM2.5 concentrations (≥13.3 µg/m3) during whole pregnancy associated with a reduced mean number of cytotoxic T cells (IRR, 0.88; 95% CI, 0.78, 0.99). Newborns exposed to higher PM10 (≥23.6 µg/m3) and PM2.5 concentrations during the first and third trimester showed greater mean number of helper T type 1 (Th1) cells (P < 0.05). Decreased number of regulatory T (Treg) cells was associated with greater short-term NO2 (IRR, 0.90; 95% CI, 0.80, 1.01) and PM10 (IRR, 0.88; 95% CI, 0.77, 0.99) concentrations. CONCLUSIONS: Prenatal exposure to TRAP, particularly in early and late gestation, impairs fetal immune system development through disturbances in cord blood leukocyte and lymphocyte distributions.

Síndrome opsoclonus-mioclonus secundario a intoxicación por duloxetina / Opsoclonus-myoclonus syndrome secondary to duloxetine poisoning

Introducción: El síndrome opsoclonus-mioclonus es una entidad poco frecuente, de origen autoinmune y que puede aparecer a cualquier edad, siendo mucho más frecuente en la edad pediátrica. Su etiología es muy diversa, frecuentemente paraneoplásica o de origen infeccioso. Los casos secundarios a intoxicación por drogas o medicamentos son infrecuentes. Caso clínico: Mujer de 43 años valorada por Psiquiatría de Enlace por sobreingesta de 80 comprimidos de duloxetina 30mg. Acude a Urgencias por un cuadro de inicio brusco de visión borrosa, temblor generalizado, dificultad para caminar y alucinaciones visuales. Ingresa en Neurología por sospecha de síndrome opsoclonus-mioclonus, recibe tratamiento esteroideo precoz, tras el que se observa mejoría clínica y recuperación temprana. Las pruebas complementarias resultan normales, excepto los niveles de duloxetina, que están muy por encima del rango normal. Discusión: El síndrome opsoclonus-mioclonus es un trastorno del movimiento infrecuente, que requiere una correcta evaluación debido a la posibilidad de estar relacionado con neoplasias subyacentes

Introduction: Opsoclonus-myoclonus syndrome is a rare entity of autoimmune origin, which can appear at any age, being much more common in paediatric patients. Its aetiology is very diverse, often of para-neoplastic or of infectious origin. Cases secondary to poisoning by drugs or other kind of medication are uncommon. Clinical case: A 43 year-old woman was examined by Liaison Psychiatry due to an overdose of 80 tablets of duloxetine 30mg. The patient went to the Emergency Service due to a sudden onset of blurred vision, general tremor, difficulty to walk, and visual hallucinations. She was admitted to the Neurology Department due to a clinical suspicion of opsoclonus-myoclonus syndrome. She received early steroid treatment, after which both clinical improvement and early recovery were observed. Complementary tests were normal except for duloxetine levels, which were found to be well above their normal range. Discussion: Opsoclonus-myoclonus syndrome is an uncommon disorder, which requires a correct diagnostic evaluation and analysis, as it could possibly be related to underlying neoplasms

Comparative study analysing women's childbirth satisfaction and obstetric outcomes across two different models of maternity care.

OBJECTIVES: To describe the differences in obstetrical results and women's childbirth satisfaction across 2 different models of maternity care (biomedical model and humanised birth). SETTING: 2 university hospitals in south-eastern Spain from April to October 2013. DESIGN: A correlational descriptive study. PARTICIPANTS: A convenience sample of 406 women participated in the study, 204 of the biomedical model and 202 of the humanised model. RESULTS: The differences in obstetrical results were (biomedical model/humanised model): onset of labour (spontaneous 66/137, augmentation 70/1, p=0.0005), pain relief (epidural 172/132, no pain relief 9/40, p=0.0005), mode of delivery (normal vaginal 140/165, instrumental 48/23, p=0.004), length of labour (0-4 hours 69/93, >4 hours 133/108, p=0.011), condition of perineum (intact perineum or tear 94/178, episiotomy 100/24, p=0.0005). The total questionnaire score (100) gave a mean (M) of 78.33 and SD of 8.46 in the biomedical model of care and an M of 82.01 and SD of 7.97 in the humanised model of care (p=0.0005). In the analysis of the results per items, statistical differences were found in 8 of the 9 subscales. The highest scores were reached in the humanised model of maternity care. CONCLUSIONS: The humanised model of maternity care offers better obstetrical outcomes and women's satisfaction scores during the labour, birth and immediate postnatal period than does the biomedical model.

Episiotomy and its relationship to various clinical variables that influence its performance.

OBJECTIVE: to understand the episiotomy rate and its relationship with various clinical variables. METHOD: a descriptive, cross-sectional, analytic study of 12,093 births in a tertiary hospital. VARIABLES: Parity, gestational age, start of labor, use of epidural analgesia, oxytocin usage, position during fetal explusion, weight of neonate, and completion of birth. The analysis was performed with SPSS 19.0. RESULTS: the global percentage of episiotomies was 50%. The clinical variables that presented a significant association were primiparity (RR=2.98), gestational age >41 weeks (RR=1.2), augmented or induced labor (RR=1.33), epidural analgesia use (RR=1,95), oxytocin use (RR=1.58), lithotomy position during fetal expulsion (RR=6.4), and instrumentation (RR=1.84). Furthermore, maternal age ≥35 years (RR=0.85) and neonatal weight <2500 g (RR=0.8) were associated with a lower incidence of episiotomy. CONCLUSIONS: episiotomy is dependent on obstetric interventions performed during labor. If we wish to reduce the episiotomy rate, it will be necessary to bear in mind these risk factors when establishing policies for reducing this procedure.

Si deseamos reducir la tasa de episiotomía será necesario tener en cuenta los factores de riesgo para establecer políticas de reducción de este procedimiento.

Adecuación entre la práctica clínica obstétrica en el Hospital Clínico Universitario Virgen de la Arrixaca (Murcia) y las recomendaciones de la Estrategia de Atención al Parto Normal / Adaptation between the obstetric clinical practise at the University Hospital Virgen de la Arrixaca (Murcia) and the recommendations of the Strategy Normal Birth Care

OBJETIVO: Comprobar el grado de adecuación de la práctica clínica obstétrica a las recomendaciones de la Estrategia de Atención al Parto Normal. Personas, material y método: Estudio descriptivo, transversal, de la actividad obstétrica de 12.093 mujeres durante el proceso de parto (en los años 2011 y 2012) en el Hospital Clínico Universitario Virgen de la Arrixaca (Murcia). Las variables estudiadas fueron: paridad, edad gestacional, inicio del parto, utilización de analgesia epidural, uso de oxitocina, posición durante la etapa de expulsión fetal, peso del recién nacido y finalización del parto. RESULTADOS: Se observa una adecuación de la práctica clínica a las recomendaciones de la Estrategia de Atención al Parto Normal en la tendencia a disminuir las siguientes practicas: el rasurado perineal (13%), el uso de enemas (7%) y el número de cesáreas urgentes (11,38%). Asimismo, se constata una tendencia a aumentar el acompañamiento al parto (88,7%), la monitorización continua (99%), la ingesta de líquidos intraparto (34,8%), el número de partos vaginales tras cesárea previa (93,1%) y el porcentaje de epidural (77%). El resto de variables estudiadas (realización de amniotomia y partos instrumentados) se mantienen sin cambios. CONCLUSIONES: Las recomendaciones de la Estrategia no se siguen en su totalidad. Se han identificado puntos de mejora. Es necesario desarrollar políticas que permitan reducir los procedimientos desaconsejados por el Ministerio de Sanidad, así como reforzar la formación del equipo interdisciplinar

OBJECTIVE: The aim is to check the adaption of the obstetric clinical practise and the recommendations of the Strategy Normal Birth Care. Persons, material and methods: This has been a descriptive, transversal and analytical study of the obstetrical activity of 12,093 childbirths which took place between 2011 and 2012 in the Clinical University Hospital Virgen de la Arrixaca (Murcia). The studied variables were: parity, gestational age, onset of labor, use of epidural analgesia, use of oxytocin, stage position during fetal expulsion, new-born weight and type of delivery (eutocic, implemented or cesarean). RESULTS: The clinical appropriateness of the recommendations of the Strategy Normal Birth Care presents a tendency to decrease in the following practises: perineal saving (13%), the use of enemas (7%) and the number of emergency caesareans (11.38%). Likewise, some practices have also had a tendency to increase: accompaniment of childbirth (88.7%), continuous monitoring (99%), intrapartum fluid intake (34.8%), the number of vaginal births after cesarean (93.1%) and the number of women with epidural (77%). There has not been any variation in the remaining studied variables (amniotomy and performing instrumental births). CONCLUSIONS: The recommendations of the Strategy are not followed entirely. Some points of improvement have been identified. It will be necessary to develop some reduction policies of procedure advised against by the Ministry, and to reinforce the interdisciplinary team training

La voz de las mujeres sometidas a mutilación genital femenina en la Región de Murcia / The voice of women subjected to female genital mutilation in the Region of Murcia (Spain)

Objetivo: Explorar las percepciones de un grupo de mujeres sometidas a mutilación genital femenina sobre el impacto de esta práctica en su salud sexual y reproductiva. Material y método: Estudio cualitativo de tipo fenomenológico. La muestra está formada por nueve mujeres, cuya media de edad es de 30 años, residen en España entre 1 y 14 años, y proceden de África subsahariana, que fueron sometidas a mutilación genital en sus países de origen. Para la recopilación de datos se ha aplicado un cuestionario sociodemográfico y una entrevista personal estructurada, en profundidad. Posteriormente se ha realizado un análisis temático del discurso. Resultados: Los discursos se han agrupado en cuatro categorías relativas a la percepción sobre la mutilación genital femenina, las relaciones de pareja, el embarazo y el parto, y la repercusión social. Conclusiones: La mutilación genital femenina es una práctica que las mujeres mantienen debido a la presión sociofamiliar, que se transmite de generación en generación y que es silenciada por las propias mujeres. Esta práctica afecta a su salud sexual y reproductiva, debido a la anorgasmia y la dispareunia que comporta. Se sienten satisfechas con la asistencia sanitaria recibida durante el embarazo y el parto, pero se identifica una planificación familiar insatisfecha en la mayoría de ellas (AU)

Objective: To explore the perceptions of a group of women who underwent female genital mutilation on the impact of this practice on their sexual and reproductive health. Methods: We performed a phenomenological qualitative study in a sample of 9 sub-Saharan Africa women, whose mean age was 30 years old and who had lived in Spain for 1 to 14 years. These women underwent genital mutilation in their countries of origin. Data was collected using a socio-demographic survey and an in-depth, structured personal interview. Subsequently, we performed a thematic discourse analysis. Results: The discourses were grouped into four categories related to participants' perceptions of female genital mutilation. These categories were intimate relationships, pregnancy, childbirth, and social impact. Conclusions: The practice of female genital mutilation is maintained due to social and family pressure, transmitted from generation to generation and silenced by women themselves. This practice affects their sexual and reproductive health, as demonstrated by anorgasmia and dyspareunia. The women were satisfied with the healthcare received during pregnancy and childbirth. Nevertheless, most of them were not satisfied with family planning (AU)

Striated muscle hamartoma in a newborn.

Striated muscle hamartoma (SMH) is an uncommon benign lesion, that is usually congenital, polypoid, and primarily located on the head and neck. The key histopathologic sign is the existence of individualized fascicles of striated muscle affecting the dermis and subcutaneous fat tissue. Here we report the case of a newborn girl with an SMH, who presented with a congenital infiltrated plaque on her chin without any other associations.

Formación y detección de la violencia de género en la profesión sanitaria / Formação e detecção da violência de gênero na profissão de saúde / Formation and detection of gender violence in the healthcare profession

Objetivos: identificar a formação em violência de gênero (VG) dos profissionais de saúde e o conhecimento do protocolo de desempenho em VG tendo recebido formação com a descoberta de abuso. Métodos: estudo transversal, observacional e descritivo. A amostra foi de 119 profissionais de saúde de Múrcia (Espanha). Foram realizadas tabelas de contingência mediante a X2 de Pearson. Resultados: 82,9% dos profissionais desconhece a existência de protocolos para VG e 92,4% refere não ter recibo formação específica. 74,8%nunca detectaram casos de maus tratos em mulheres em sua prática profissional. O conhecimento dos protocolos de atuação e formação específica está significativamente relacionado (p<0,05) a detecção de VG. Conclusão: a formação, o conhecimento dos protocolos de atuação e uma maior sensibilização dos profissionais de saúde para o tema incrementariam o número de detecções de maus tratos, reduzindo problemas crônicos de saúde e gastos sanitários.

Aim: to identify the specific formation health professionals have on gende rviolence (GV) and knowledge about the actuation protocol on GV having received formation in mistreatment detection. Methods: transversal, observational and descriptive study. The sample size was 119 health professionals from Murcia (Spain). A statistical study of contingency tables was made, using the X2 of Pearson. Results: 82.9% of the professionals don’t know if there is a protocol of GV and 92.4% report never having received specific training. 74.8% have never detected a case of abuse in women during practice. Knowledge of the protocols and specific training is significantly related (p <0.05) with the detectionof GV. Conclusions: the specific formation, the knowledge of domestic violence protocols and a greater sensitization of health professionals would increase the number of detections of poorly treated women, reducing chronic health problems and health care spending.

Conversion from Prograf to Advagraf in stable paediatric renal transplant patients and 1-year follow-up.

BACKGROUND: The conversion from Prograf to Advagraf on a 1:1 (mg:mg) basis has been questioned in light of the publication of studies showing a decrease in tacrolimus blood concentrations after the administration of Advagraf. METHODS: The bioavailability of Prograf and Advagraf was evaluated in an open-label conversion study in 21 stable renal transplant paediatric patients. Serial blood samples for determining tacrolimus levels were collected during a 24-h period before (on Prograf) and after (on Advagraf) conversion. Tacrolimus pharmacokinetic parameters were calculated using a non-compartmental approach and the relative bioavailability calculated. Clinical and analytical data were obtained at 30, 90, 180 and 360 days after study enrolment. RESULTS: The mean ratio and 90 % confidence interval (CI) for peak plasma drug concentration (C(max)) and the area under the time-concentration curve during the first 24 h (AUC(0-24)) were 81.54 (95 % CI 71.6-92.87) and 87.19 (95 % CI 79.91-95.13), respectively. Renal glomerular filtration rate remained stable over the course of the follow-up. Two patients presented clinical events unrelated to tacrolimus. Tacrolimus levels decreased in the first month, the dose/level ratio increased between months 1 and 6 and slight dose adjustments were required during the follow-up period. CONCLUSIONS: Our results show that Advagraf bioequivalence cannot be ensured in this population. Significant changes in tacrolimus levels and dose were observed on long-term follow-up.
