Compatibility of prolonged infusion antibiotics during Y-site administration.

BACKGROUND: Antimicrobial resistance is a threat to global public health. The use of prolonged infusions in the hospital setting for certain antimicrobials is widely increasing in order to improve their efficacy and safety, including resistance development. Due to limited vascular access, it is important to clarify whether they can be infused through the same line with other drugs during Y-site administration. AIM: The aim of this review is to update and summarize the evidence on Y-site compatibility of antibacterial agents administered as prolonged infusions in intensive care units (ICUs). STUDY DESIGN: A literature review of PubMed, EMBASE and Trissel's Handbook on Injectable Drugs databases was conducted on the compatibility of selected antimicrobials administered simultaneously at a Y-site connection with parenteral nutrition and other widely used drugs in ICUs. All articles published up to October 30, 2021, in English or Spanish were included, regardless of the type of publication (original articles, case reports, letters, etc.). Eligible antimicrobials were those that can be administered as prolonged infusions: ceftazidime, cefepime, piperacillin/tazobactam, meropenem, ceftolozane/tazobactam, ceftaroline, cloxacillin, ceftobiprole, vancomycin and fosfomycin. RESULTS: A total of 1302 drug-to-drug potential combinations were explored, 196 (15.05%) were found to be incompatible, and in 541 (41.55%), data were not available. The results were presented in a simple 2-dimensional consultation chart as a quick reference for health care professionals. CONCLUSIONS: This review provides useful and reliable information on the compatibility of antimicrobials administered as Y-site infusion with other drugs commonly used in the critical setting. This review contributes to patient safety in nursing practice. RELEVANCE TO CLINICAL PRACTICE: To our knowledge, this is the first review on Y-site compatibility of antimicrobials used as prolonged infusions with other commonly used drugs, including anti-emetics, analgesics and anti-epileptic and parenteral nutrition. The results of the current review need to be addressed to promote the knowledge sharing between health professionals and improve the quality and safety of patients. We believe that this review may serve as a simple and effective 2-dimensional updated drug-to-drug compatibility reference chart for critical care nurses.

Anafilaxia. Taller de casos clínicos / Anaphylaxis. Clinical case workshop

La anafilaxia en la infancia es una enfermedad grave, potencialmente mortal, que precisa ser diagnosticada y recibir tratamiento del pediatra de modo inmediato. La principal causa de anafilaxia en la infancia es la alergia a los alimentos. Su diagnóstico es fundamentalmente clínico y se debe sospechar cuando de modo agudo, en minutos o pocas horas, aparecen en un niño manifestaciones cutáneas (urticaria, angioedema) acompañadas de manifestaciones respiratorias o circulatorias. Ocasionalmente la clínica cutánea puede no aparecer, lo cual dificulta el diagnóstico. El tratamiento de elección es la administración precoz, ante la sospecha, de adrenalina intramuscular en la cara externa del muslo. En la edad pediátrica no existe ninguna contraindicación para el uso de adrenalina ante un caso de anafilaxia. La administración de cualquier otro tratamiento no es prioritaria y su uso dependerá de la evolución de la anafilaxia y siempre después de haber administrado adrenalina intramuscular. Todo niño con anafilaxia deberá acudir a un hospital, aunque su anafilaxia haya mejorado o revertido tras la adrenalina, y permanecerá unas horas en observación. Será dado de alta con un informe escrito en donde se especifiquen los posibles desencadenantes del cuadro y cómo evitarlos, y se le prescribirá al menos un autoinyector de adrenalina adecuado a su peso. Deben ser instruidos, tanto el niño como su familia y cuidadores, en el manejo del autoinyector de adrenalina al alta y posteriormente de modo regular por su pediatra por medio de simuladores. Siempre tiene que ser remitido para valoración y estudio a un especialista en Alergia Infantil

Anaphylaxis in childhood is a serious, life-threatening disease that needs to be diagnosed and treated immediately by the pediatrician. The main cause of anaphylaxis in childhood is food allergy. Its diagnosis is fundamentally clinical and should be suspected when, in minutes or a few hours, acute skin manifestations appear in a child (urticaria, angioedema), accompanied by respiratory or circulatory manifestations. Occasionally the cutaneous clinic may not appear, which makes diagnosis difficult. The treatment of choice is the early administration, on suspicion, of intramuscular adrenaline on the outer side of the thigh. In the pediatric age there is no contraindication for the use of adrenaline in the case of anaphylaxis. The administration of any other treatment is not a priority and its use will depend on the evolution of anaphylaxis and always after administering intramuscular adrenaline. Every child with anaphylaxis should go to a hospital, even if their anaphylaxis has improved or reversed after adrenaline, and will remain in observation for a few hours. They will be discharged with a written report specifying the possible triggers of the box and how to avoid them, and they will be prescribed at least one adrenaline autoinjector appropriate to their weight. They must be instructed, both the child and his family and caregivers, in the handling of the adrenaline autoinjector at discharge and later on a regular basis by his pediatrician through simulators. They always have to be sent for assessment and study to a specialist in Child Allergy

Calidad de vida y características asociadas del síndrome de piernas inquietas en la población adulta de Burgos, España / Quality of life and associated characteristics of restless legs syndrome in the adult population of Burgos, Spain

Introducción. El síndrome de piernas inquietas (SPI) es un trastorno neurológico con una prevalencia de hasta un 15%, cuyo impacto sobre la calidad de vida resulta poco conocido. Objetivo. Analizar el impacto del síndrome de piernas inquietas (SPI) en la calidad de vida relacionada con la salud. Sujetos y métodos. Estudio descriptivo transversal. Se incluyó una muestra aleatoria, estratificada por edad, de 1.275 sujetos mayores de 18 años en el área urbana de Burgos, con las estimaciones de prevalencia, 10%; alfa, 5%; precisión, 3%; y pérdidas, 70%, usando un estudio en dos fases (cribado y confirmación diagnóstica de casos de SPI y no casos por un médico). Los datos clínicos y sociodemográficos se recogieron usando cuestionarios semiestructurados: European Quality of Life-5 Dimensions, Restless Legs Syndrome Quality of Life Questionnaire, escala de Epworth, escala de Goldberg, escala del sueño y cuestionario internacional del síndrome de piernas inquietas. Resultados. La prevalencia del SPI fue del 5,6% (IC 95%: 2,5-8,7%). El 79,4% de los casos eran mujeres; sólo el 7% tenía un diagnóstico previo de SPI. El dolor intenso, el insomnio y la depresión-ansiedad fueron más frecuentes en los pacientes con SPI que en los controles (p < 0,001 en los tres casos). La calidad de vida entre los pacientes con SPI, especialmente en las mujeres, fue peor que en los controles (p < 0,001). En el 11,7% de los casos, el SPI produjo dificultades para trabajar. Conclusiones. El SPI está asociado con ansiedad-depresión, con un significativo impacto en el sueño, en las relaciones sociales y laborales, y en la calidad de vida relacionada con la salud (AU)

Introduction. Restless legs syndrome (RLS) is a neurological disorder with a prevalence of up to 15%, although little is known about its impact upon quality of life. Aim. To analyse the impact of RLS on health-related quality of life. Subjects and methods. A descriptive cross-sectional study. A random sample of 1,275 subjects over 18 years old, stratified by age, was taken from the urban area of Burgos, with an estimated prevalence, 10%; alpha, 5%; accuracy, 3%; and losses, 70%, using a two-phase study (screening and diagnosis of cases of RLS and non-cases confirmed by a doctor). The clinical and sociodemographic data were collected by means of semi-structured questionnaires, the European Quality of Life-5 Dimensions, the Restless Legs Syndrome Quality of Life Questionnaire, the Epworth Scale, the Goldberg Scale, the Sleep Scale and the International Restless Legs Syndrome Rating Scale. Results. The prevalence of RLS was 5.6% (CI 95%: 2.5-8.7%). Of the total number of cases, 79.4% were women and only 7% had been previously diagnosed with RLS. Intense pain, insomnia and depression-anxiety were more frequent among the cases of RLS than in the controls (p < 0.001 in the three cases). The quality of life among the cases of RLS, especially in women, was poorer than among the controls (p < 0.001). For 11.7% of the cases, RLS made it difficult for the patients to work. Conclusions. RLS is associated with depression-anxiety, with a significant impact on sleep, on social and work relationships, and on the health-related quality of life (AU)

Prevalencia, valor diagnóstico y características clínicas asociadas a la presencia de niveles circulantes y depósitos renales de anticuerpos contra el receptor tipo M de la fosfolipasa A2 en nefropatía membranosa idiopática / Prevalence, diagnostic value and clinical characteristics associated with the presence of circulating levels and renal deposits of antibodies against the M-type phospholipase A2 receptor in idiopathic membranous nephropathy

El receptor tipo M de la fosfolipasa A2 (PLA2R) ha sido identificado como uno de los antígenos diana de la respuesta autoinmune en la nefropatía membranosa (NM) idiopática. La prevalencia de anticuerpos anti-PLA2R en enfermos con NM idiopática oscila en torno al 70 %, pero varía en función del área geográfica y hasta la fecha no se ha demostrado que la presencia de anti-PLA2R se asocie a un determinado perfil clínico de presentación de la enfermedad. Métodos: Se estudiaron 64 adultos con síndrome nefrótico y diagnóstico de NM confirmado por biopsia renal. Cuarenta y siete pacientes presentaban NM idiopática y 17 NM secundaria. Se determinó la presencia de anticuerpos circulantes antiPLA2R por inmunofluorescencia indirecta (IFI) y su título mediante ELISA. La presencia de depósitos renales de anticuerpos anti-PLA2R se determinó mediante técnicas de inmunohistoquímica. Se calculó la sensibilidad y especificidad de las técnicas de IFI y ELISA para la identificación de los enfermos con depósitos renales y para la identificación de los enfermos con NM idiopática. Se analizó si había diferencias en el perfil clínico de la enfermedad en el momento del diagnóstico en función de la presencia o no de anticuerpos anti-PLA2R. Resultados: No se observaron diferencias significativas en las variables clínico-demográficas entre enfermos con NM idiopática y secundaria. La prevalencia de depósitos glomerulares de anti-PLA2R por IHQ fue del 76,6 %. Las técnicas de IFI y de ELISA tuvieron una sensibilidad (94,4 % IFI y 97,2 % ELISA) y una especificidad (100 %) similar para la identificación de los enfermos con depósitos renales de anti-PLA2R. La determinación de anti-PLA2R por IFI identificó a los enfermos con NM idiopática con una sensibilidad del 72,3 % y una especificidad del 94,2 %. Un título de anticuerpos > 15 RU/ml medido por ELISA tuvo una sensibilidad del 74,45 % y una especificidad del 94,2 % para la identificación de los enfermos con NM idiopática. Los pacientes con NM idiopática y anti-PLA2R presentaron cifras de proteinuria significativamente mayores (13,25 [P25-P75: 9,05-15,87] frente a 9,43 [P25-P75: 6,30-15] g/día, p: 0,018). No se apreció correlación estadística entre el título de anticuerpos medido por ELISA con la edad, el filtrado glomerular, la albuminemia y la proteinuria en 24 horas. Conclusiones: Las técnicas empleadas para la determinación de anti-PLA2R en pacientes con NM presentan alta especificidad para el diagnóstico de formas idiopáticas de la enfermedad glomerular. La frecuencia con la que se identifican pacientes con NM y anti-PLA2R es parecida a la descrita en estudios previos. La tinción por inmunohistoquímica es el método más sensible para la detección de casos de NM asociados a presencia de anticuerpos anti-PLA2R. Las técnicas de IFI y de ELISA permiten la detección de anticuerpos circulantes anti-PLA2R en la mayor parte de los enfermos con depósitos renales, pero con muy baja frecuencia pueden dar resultados falsamente negativos. La concordancia de estas pruebas es alta. Los enfermos con NM idiopática y depósitos renales de anticuerpos anti-PLA2R tienen mayor proteinuria que los enfermos anti-PLA2R negativos, pero las diferencias tienen escasa relevancia clínica (AU)

The M-type phospholipase A2 receptor (PLA2R) has been identified as one of the target antigens of the autoimmune response in idiopathic membranous nephropathy (MN). The prevalence of anti-PLA2R antibodies in patients with idiopathic MN is around 70% but this varies in accordance with geographic region, and until present, anti-PLA2R has not been shown to be associated with any particular clinical profile of the disease. Methods: We studied 64 adults with nephrotic syndrome who were diagnosed with MN, confirmed by renal biopsy. Forty-seven patients had idiopathic MN and 17 had secondary MN. We determined the presence of circulating anti-PLA2R antibodies by indirect immunofluorescence (IIF) and their titre by ELISA, and we analysed the presence of anti-PLA2R antibody renal deposits by immunohistochemical techniques. We calculated the sensitivity and specificity of the IIF and ELISA techniques for the identification of patients with renal deposits and for the identification of those with idiopathic MN and we tested whether there were differences in the clinical profile of the disease at the time of diagnosis according to the presence or absence of anti-PLA2R antibodies. Results: We did not observe significant differences in the clinical-demographic variables between patients with idiopathic and secondary MN. The prevalence of anti-PLA2R glomerular deposits by IHC was 76.6%. The IIF and ELISA techniques had a similar sensitivity (IIF 94.4% and ELISA 97.2%) and specificity (100%) for the identification of patients with anti-PLA2R renal deposits and the detection of circulating anti-PLA2R antibodies. The determination of anti-PLA2R by IIF identified patients with idiopathic MN with a sensitivity of 72.3% and a specificity of 94.2%. A titre of antibodies >15RU/ml measured by ELISA had a sensitivity of 74.45% and a specificity of 94.2% for the identification of patients with idiopathic MN. Patients with idiopathic MN and anti-PLA2R had significantly higher proteinuria figures (13.25 [P25-P75: 9.05-15.87] compared to 9.43 [P25-P75: 6.30-15] g/day, P:.018). No statistical correlation was observed between the antibody titre measured by ELISA and age, glomerular filtration rate or 24-hour proteinuria or albuminaemia. Conclusions: The techniques employed to determine anti-PLA2R in patients with MN are highly specific for the diagnosis of idiopathic forms of the glomerular disease. The frequency with which patients with MN and anti-PLA2R were identified is similar to that reported in previous studies. Staining by immunohistochemistry is the most sensitive method for detecting cases of MN associated with the presence of anti-PLA2R antibodies. The IIF and ELISA techniques allow circulating anti-PLA2R antibodies to be detected in most patients with renal deposits, but they may very infrequently have false negative results. The concordance of these tests is high. Patients with idiopathic MN and anti-PLA2R antibody renal deposits have higher proteinuria than patients that are anti-PLA2R negative, but the differences have little clinical importance (AU)

Multi-Stencil Streamline Fast Marching: A General 3-D Framework to Determine Myocardial Thickness and Transmurality in Late Enhancement Images.

We propose a fully 3-D methodology for the computation of myocardial nonviable tissue transmurality in contrast enhanced magnetic resonance images. The outcome is a continuous map defined within the myocardium where not only current state-of-the-art measures of transmurality can be calculated, but also information on the location of nonviable tissue is preserved. The computation is done by means of a partial differential equation framework we have called multi-stencil streamline fast marching. Using it, the myocardial and scarred tissue thickness is simultaneously computed. Experimental results show that the proposed 3-D method allows for the computation of transmurality in myocardial regions where current 2-D methods are not able to as conceived, and it also provides more robust and accurate results in situations where the assumptions on which current 2-D methods are based-i.e., there is a visible endocardial contour and its corresponding epicardial points lie on the same slice-, are not met.

Tratamiento de la glomeruloesclerosis focal y segmentaria idiopática: opciones en caso de resistencia a corticosteroides y anticalcineurínicos / Treatment of idiopathic focal segmental glomerulosclerosis: options in the event of resistance to corticosteroids and calcineurin inhibitors

La mitad de los enfermos con síndrome nefrótico causado por glomeruloesclerosis focal y segmentaria (GFS) primaria presentan resistencia al tratamiento con esteroides. En caso de corticorresistencia, la mejor opción basada en la evidencia ha sido clásicamente el tratamiento con inhibidores de calcineurina, aunque estudios recientes indican que micofenolato podría tener una eficacia similar. En los enfermos con resistencia a anticalcineurínicos, no existe ninguna opción capaz de modificar el curso clínico de la enfermedad, avalada por ensayos clínicos de diseño apropiado, aunque en estudios observacionales se ha sugerido la posible utilidad de micofenolato, sirolimus, rituximab, aféresis o altas dosis de galactosa como opciones terapéuticas. En las GFS de origen idiopático, resistentes a esteroides y anticalcineurínicos, antes de tomar la decisión de ensayar o no otros fármacos inmunosupresores, podría ser apropiado realizar un análisis sistemático que contemplara: 1) considerar si la dosis y el tiempo de tratamiento con esteroides y anticalcineurínicos fueron adecuados; 2) analizar el nivel de expresión de la glicoproteína P en los linfocitos; 3) considerar realizar una nueva biopsia renal en caso de que en la primera no se disponga de estudio de microscopía electrónica; 4) en enfermos jóvenes, considerar un estudio genético para descartar la presencia de la variante p.R229Q de la podocina en combinación con mutaciones heterozigotas en NPHS2, y 4) considerar la gravedad y dificultad de manejo del síndrome nefrótico y la probabilidad de pérdida progresiva de la función renal. En la actualidad, hay múltiples vías de estudio para intentar identificar los mecanismos patogénicos causantes de la lesión podocitaria y hay también en curso varios estudios para analizar la eficacia de fármacos como adalimumab, fresolimumab, rosiglitazona, ACTH (corticotropina) o galactosa a altas dosis, cuyos resultados preliminares han generado expectativas que requieren ser confirmadas en estudios clínicos a mayor escala. En un futuro, es posible que el mejor conocimiento de la vía o vías patogénicas causantes de GFS permita diferenciar entre las formas inmunomodulables y las que no lo son, pero, hoy por hoy, este desafío continúa plenamente vigente

Half of patients with nephrotic syndrome caused by primary focal segmental glomerulosclerosis (FSGS) have resistance to treatment with steroids. In the case of corticosteroid resistance, the best evidence-based option has classically been treatment with calcineurin inhibitors, although recent studies indicate that mycophenolate may have similar efficacy. In patients with resistance to calcineurin inhibitors, there is no option that allows the clinical course of the disease to be modified, and this is supported by appropriately designed clinical trials, although observational studies have suggested the potential usefulness of mycophenolate, sirolimus, rituximab, apheresis or high galactose doses as treatment options. In FSGS of idiopathic origin, resistant to steroids and calcineurin inhibitors, before taking the decision whether or not to test other immunosuppressive drugs, it might be appropriate to conduct a systematic analysis that considers: 1) evaluating whether the dose and duration of treatment with steroids and calcineurin inhibitors were suitable, 2) analysing the level of P-glycoprotein expression in lymphocytes, 3) performing a new renal biopsy if there is no electron microscopic study available for the first, 4) in young patients, considering a genetic study to rule out the presence of the podocin variant pR229Q in combination with heterozygous mutations in NPHS2, and 5) evaluating the seriousness and difficulty of managing the nephrotic syndrome and the likelihood of progressive loss of renal function. Currently, there are multiple study avenues that attempt to identify the pathogenic mechanisms that cause podocyte injury and there are also several studies underway to analyse the efficacy of drugs such as adalimumab, fresolimumab, rosiglitazone, ACTH (corticotropin) or galactose at high doses, whose preliminary results have generated expectations that require confirmation in larger-scale clinical studies. In the future, it is possible that a better understanding of the pathogenic pathway or pathways that cause FSGS may allow differentiation between immunomodulable and non-immunomodulable forms, however, this continues to be a challenge for today

Uno de los retos a los que debe enfrentarse la nefrología moderna es el de identificar biomarcadores que se asocien a patrones anatomopatológicos o a mecanismos patogénicos definidos y permitan el diagnóstico no invasivo de la causa del síndrome nefrótico o establecer subgrupos pronósticos en cada tipo de enfermedad, prediciendo la respuesta al tratamiento y/o la aparición de recidivas. Los avances en el conocimiento de la patogenia de las distintas enfermedades causantes de síndrome nefrótico, sumados al progresivo desarrollo y estandarización de las técnicas de proteómica plasmática y urinaria, han permitido ir identificando un número creciente de moléculas que podrían ser útiles para los fines anteriormente mencionados. En el momento actual, los datos de muchos de los candidatos identificados, sobre todo mediante técnicas de proteómica, son todavía muy preliminares. En la presente revisión, se resume la evidencia disponible sobre las moléculas que en la actualidad cuentan con mayor evaluación en estudios clínicos (AU)

One of the major challenges modern nephrology should face is the identification of biomarkers that are associated with histopathological patterns or defined pathogenic mechanisms that might aid in the non-invasive diagnosis of the causes of nephrotic syndrome, or in establishing prognosis sub-groups based on each type of disease, thus predicting response to treatment and/or recurrence. Advancements in the understanding of the pathogenesis of the different diseases that cause nephrotic syndrome, along with the progressive development and standardisation of plasma and urine proteomics techniques, have facilitated the identification of a growing number of molecules that might be useful for these objectives. Currently, the available information for many of the possible candidates identified to date, above all those discovered using proteomics, are still very preliminary. In this review, we summarise the available evidence for the different molecules that have been best assessed using clinical studies (AU)

[Effectiveness of the application of therapeutic touch on weight, complications, and length of hospital stay in preterm newborns attended in a neonatal unit]. / Efectividad de la aplicación de toques terapéuticos en el peso, las complicaciones y los días de estancia, en recién nacidos pretérmino ingresados en una unidad de neonatología.

OBJECTIVE: To determine the effectiveness of therapeutic touch on weight, the presence of postnatal complications, and length of hospital stay in preterm newborns, as well as on parental satisfaction with the care provided. METHOD: We performed an experimental study in the Neonatal Intensive Care Unit of the Virgen Macarena University Hospital in Seville (Spain). Seventy eight premature neonates were randomly assigned to one of the comparison groups (39 in the control group and 39 in the experimental group). The outcome variables of weight, length of hospital stay, the presence of complications, and parental satisfaction were evaluated. Control variables related to maternal socio-demographic and clinic characteristics were also measured. The intervention was based on the application of therapeutic touch. RESULTS: The mean weight in grams was 1,867.80 (SD=149.72) in the experimental group and 1,860 (SD=181.92) in the control group (t=0.148; p=0.883). Length of hospital stay was 16.82 (SD=6.47) in the experimental group and 20.30 (SD=8.04) in the control group (t=2.100; p=0.039). Complications developed in 5.3% of the premature neonates in the experimental group and in 20% of those in the control group (chi(2)=3.78; p=0.049). The odds ratio for developing complications was 1.673 (CI 1.089-2.571). CONCLUSIONS: The application of therapeutic touch reduces the length of hospital stay and the presence of complications. Nevertheless, further research in larger samples is required.

Transporte aéreo sanitario del paciente adulto crítico / Medical air transport for the critically ill adult patient

La progresiva implantación de los servicios de emergencias ennuestra sociedad, como consecuencia de la gran demanda de asistenciasanitaria en el lugar donde se producen los accidentes, hacambiado la concepción del transporte sanitario: se ha pasado de“transportar para salvar” a “salvar para luego transportar”.El traslado del paciente en un medio de transporte aéreo requiereunos cuidados específicos derivados de su situación crítica y de lascaracterísticas propias del medio utilizado.En este trabajo se expone una clasificación de los medios aéreos,que han pasado de ser rudimentarios globos aerostáticos a sofisticadasaeronaves presurizadas/no presurizadas (helicópteros y aviones)y se describe un protocolo de los cuidados necesarios antes,durante y después del traslado aéreo de un paciente adulto críticohospitalizado

The progressive implantation of emergency services in our society,as a result of the high demand for healthcare at the site wherethe accidents occur, has changed the idea of medical transportation,going from “to transport to safe a live” to “safe a life andthen to transport”.The transportation of the patient in an air transportation systemrequires specific care derived from a critical situation and theactual characteristics of the used transportation mode.This paper presents a classification of air means that have gonefrom being rudimentary aerostatic balloons to sophisticated pressurised/non-pressurised aircrafts (helicopters and airplanes). Thepaper also describes a protocol of the appropriate patient carebefore, during and after a critically ill hospitalised adult patient islifted by air

In vivo studies on mouse erythrocytes linked to transferrin.

Transferrin (Tf), a plasma protein with numerous, highly specific receptors in proliferating and differentiating cells was already discussed as a targeting ligand for drugs and liposomes in previous studies. In this paper, we deal with erythrocytes linked to Tf as possible physiological targeting carrier systems for delivering anticancer drugs. For that purpose we have used glutaraldehyde (0.1%) as a coupling agent between Tf and erythrocytes. The highest amount of Tf linked to erythrocytes turned out to be 0.76 +/- 0.13 microg Tf/10(6) cells, while reaching 65% of cell recovery. After 13 days, the Tf-erythrocytes hemolysis reached 50%, with transferrin still coupled to erythrocytes. The in vivo kinetic behaviour of intravenously injected 51Cr-Tf-erythrocytes showed a reduced half-life to hours as compared to days of controls. However, a considerable percentage of Tf-erythrocytes (close to 20%) remained circulating for a relatively long period (around 2 days), which made possible the specific targeting by these carrier systems. In vivo biodistribution studies indicated that 51Cr-Tf-erythrocytes rapidly accumulated in the different studied organs (liver, spleen, lungs, kidneys, femur-tibia, and heart), suggesting a selective removal of Tf-erythrocytes by the cells of the mononuclear phagocytic system present mainly in liver and spleen. On the other hand, Tf-erythrocytes showed a poor targeting of heart tissue, therefore a reduced cardiac toxicity should be expected after administration of erythrocyte-encapsulated drugs. The presence of Tf-erythrocytes in femur-tibia and spleen could be related to the Tf-specific binding to the hematopoietic cells containing Tf receptors. The final results of this study encourage additional research on Tf-erythrocyte to investigate the relationship between transferrin-mediated targeting by carrier erythrocytes and uptake of different erythrocyte-encapsulated drugs. Consequently, the current study showed possible use of these carriers as a potential therapeutic tool for drug targeting in animal models with alterations affecting mononuclear phagocytic system or carcinomas of various origins whose cells show elevated number of Tf receptors.
