RESUMO

Objective: This study aimed to explore the predictive value of neutrophil gelatinase-associated lipocalin (NGAL) and β2 microglobulin (β2-MG) in blood and urine amongst patients with acute pancreatitis (AP) and acute kidney injury (AKI). Methods: The clinical data of 80 patients with AP, who were treated in the study hospital from November 2019, to November 2022, were selected for retrospective analysis. They were divided into AKI group (n = 25) and non-AKI group (n = 55) in accordance with the presence of AKI. The levels of serum NGAL and β2-MG in blood and urine were compared in both groups. Logistic regression analysis was used to explore the influencing factors of AKI in patients with AP and the receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of serum NGAL and β2-MG in the blood and urine of patients with AKI and AP. Results: The AKI group had higher serum NGAL and β2-MG in blood and urine than the non-AKI group. Logistic regression analysis showed that the high levels of serum NGAL and β2-MG in blood and urine were risk factors for AKI in patients with AP (p < 0.05). The areas under the curve (AUC), sensitivity and specificity of the combined prediction were 0.97, 84.00% and 98.20%, respectively, showing a good prediction efficiency. Conclusions: The increased levels of serum NGAL and β2-MG in blood and urine have a warning significance for patients with AP and AKI and a certain predictive value. So, their combination detection provides a reliable reference for the identification of clinical AKI (AU)

RESUMO

INTRODUCCIÓN: Recientemente, se ha incorporado a nuestras posibilidades terapéuticas una nueva clase de dializadores, las membranas de medio cut-off (MCO), diseñadas para mejorar la permeabilidad y que podrían alcanzar una eficacia similar a la hemodiafiltración. Para aumentar el conocimiento sobre su uso, el objetivo del estudio fue valorar en las membranas de MCO el efecto de la superficie y del flujo sanguíneo (Qb) sobre la eficacia depurativa. MATERIAL Y MÉTODOS: Se incluyó a 19 pacientes en programa de hemodiálisis. Cada paciente recibió 6 sesiones, en las que se varió la superficie de membrana, de 1,7 o 2,0 m2, y el Qb (300, 350, 400 o 450 mL/min). En cada sesión se determinaron diferentes solutos al inicio y al final de la diálisis. RESULTADOS: El cambio de superficie del dializador no mostró diferencias significativas en la depuración de pequeñas o grandes moléculas, sin cambios en la pérdida de albúmina. El aumento del Qb se acompañó de un aumento de depuración de pequeñas moléculas, sin mostrar diferencias en el porcentaje de reducción de β2-microglobulina, mioglobina, prolactina, α1-microglobulina y α1-glicoproteína ácida, a excepción de alguna comparación con Qb 450mL/min. Tampoco se observaron diferencias en la pérdida de albúmina en el líquido de diálisis, inferior a 2,5 g en todas las situaciones. CONCLUSIÓN: El incremento de la superficie de 1,7 a 2,0 m2 en el dializador de MCO no ha significado una mayor eficacia depurativa. En estos dializadores el aumento del Qb no parece ser tan determinante como en la hemodiafiltración, a excepción de la depuración de pequeñas moléculas


INTRODUCTION: Recently, a new class of dialyzers, medium cut-off membranes (MCO), designed to improve the permeability, which could provide an efficacy similar to hemodiafiltration, have been incorporated into our therapeutic possibilities. To increase the knowledge about its use, the objective of the study was to evaluate the effect of the surface and blood flow (Qb) on the depurative efficacy in the MCO membranes. MATERIAL AND METHODS: We included 19 patients in the hemodialysis. Each patient received 6 sessions, in which the membrane surface was varied, from 1.7 to 2.0 m2, and/or the Qb (300, 350, 400 or 450 mL/min). In each session, different solutes were determined at the beginning and end of dialysis. RESULTS: The surface change of the dialyzer did not show significant differences in the removal of small or large molecules, without changes in albumin loss. The increase in Qb was accompanied by an increase in clearance of small molecules, without showing differences in the percentage reduction of β2-microglobulin, myoglobin, prolactin, α1-microglobulin and α1-acid glycoprotein, except for some comparison with Qb 450 mL/min. There were also no differences in the loss of albumin in the dialysis fluid, less than 2.5 g in all situations. CONCLUSION: The increase of the surface area from 1.7 to 2.0 m2 in the MCO dialyzer has not meant a greater depurative effectiveness. In these dialyzers the increase of Qb does not seem to be as determinant as in hemodiafiltration except for the clearance of small molecules

RESUMO

OBJECTIVE: The common reference genes of choice in relative gene expression studies based on quantitative real time polymerase chain reaction, ACTB and B2M, were shown to be regulated differently in respect to tissue type. In this study, the stability of the selected housekeeping genes for normalizing the qPCR data were identified in the tumor and its adjacent tissues in invasive breast cancer, and the variability of their levels according to the stages and the histopathologic subtypes was analyzed. METHODS: Four housekeeping genes: PUM1, RPL13A, B2M, and ACTB were analyzed in 99 surgically excised tissue specimens (50 tumor, 45 tumor adjacent and 4 normal breast tissues). Three of the most common softwares (GeNorm, NormFinder, and BestKeeper) were used for calculation purposes. RESULTS: When all of the tissue samples were included in analyses, PUM1 was the most stable gene according to calculations made with both NormFinder and BestKeeper; while PUM1/RPL13A combination was the most stable by GeNorm software. The PUM1 gene was also identified as the most stable gene among the four in all sample groups (in both Estrogen Receptor positive and Estrogen Receptor negative subgroups of invasive breast carcinoma and in normal breast tissue) according to calculations made using the NormFinder software. CONCLUSION: While suggesting PUM1 is one of the most stable single gene and the PUM1/RPL13A pair as one of the best housekeeping genes for the normalization of expression studies in invasive breast tumor studies, it will be more practical to evaluate stability once more and decide upon the reference gene accordingly within the sample group itself (AU)

RESUMO

OBJETIVO: El objetivo principal del estudio es el análisis de la evolución de la función renal residual según la técnica de diálisis (diálisis peritoneal o hemodiálisis) y la frecuencia del tratamiento (dos o tres sesiones de hemodiálisis a la semana). Como objetivos secundarios hemos estudiado la evolución de la concentración sérica de β2-microglobulina y la respuesta de la anemia a los agentes eritropoyéticos. MATERIAL Y MÉTODOS: Se incluyeron 193 enfermos no anúricos, que comenzaron tratamiento renal sustitutivo con diálisis en nuestro hospital entre el 1 de enero de 2006 y el 31 de diciembre de 2011, y tuvieron un seguimiento superior a tres meses. De ellos, 61 enfermos (32 %) iniciaron tratamiento con dos sesiones de hemodiálisis a la semana, 49 enfermos (25 %) con tres sesiones de hemodiálisis a la semana y 83 enfermos (43 %) con diálisis peritoneal. Se midió el filtrado glomerular como la media de los aclaramientos renales de urea y creatinina. RESULTADOS: El ritmo de descenso del filtrado glomerular fue igual en los enfermos que comenzaron tratamiento con la pauta de dos sesiones de hemodiálisis a la semana y con diálisis peritoneal (mediana 0,18 ml/min/mes) y fue superior en los enfermos que iniciaron tratamiento con tres sesiones de hemodiálisis a la semana (mediana 0,33 ml/min/mes, p < 0,05). A lo largo de toda la evolución, la tasa de filtrado glomerular no mostró diferencias entre el grupo que comenzó con dos sesiones semanales de hemodiálisis y el grupo de diálisis peritoneal, y fue inferior en el grupo que comenzó tratamiento con tres sesiones de hemodiálisis a la semana con significación estadística durante los primeros 24 meses de seguimiento. En los tres grupos de enfermos la concentración de β2-microglobulina fue aumentando conforme disminuía el filtrado glomerular y fue más elevada en el grupo de tres sesiones de hemodiálisis a la semana durante los primeros 12 meses de seguimiento. En todos los controles realizados hubo una correlación negativa entre la concentración de β2-microglobulina y el filtrado glomerular (p < 0,001). La dosis de eritropoyetina se relacionó negativamente con el filtrado glomerular. Los enfermos que comenzaron con dos sesiones de hemodiálisis a la semana necesitaron una dosis menor de eritropoyetina que los enfermos que iniciaron tratamiento renal sustitutivo con tres sesiones a la semana. La dosis de eritropoyetina en el grupo de diálisis peritoneal fue inferior a la del grupo de dos hemodiálisis a la semana, a pesar de mantener un filtrado glomerular similar. CONCLUSIONES: Los enfermos que comienzan tratamiento con dos sesiones de hemodiálisis a la semana experimentan el mismo ritmo de descenso de la función renal residual que los enfermos tratados con diálisis peritoneal. La evolución de la concentración de β2-microglobulina es paralela a la del filtrado glomerular. Los enfermos tratados con dos sesiones de hemodiálisis necesitan una dosis de eritropoyetina menor que los que reciben tres sesiones a la semana, pero significativamente superior a la de los enfermos tratados con diálisis peritoneal, lo cual indica que la respuesta de la anemia a los agentes eritropoyéticos no solo está relacionada con la función renal residual, sino también con otros factores inherentes a la técnica de diálisis


OBJECTIVE: The main objective of the study was to analyse the progression of residual renal function according to the dialysis technique (peritoneal dialysis or haemodialysis) and the frequency of treatment (two or three sessions of haemodialysis per week). As secondary objectives, we studied the progression of the serum concentration levels of β2 microglobulin and the response of anaemia to erythropoietic agents. MATERIAL AND METHOD: 193 non-anuric patients were included and began renal replacement therapy with dialysis in our hospital between 1 January 2006 and 31 December 2011, with a follow-up period of over three months. 61 patients (32%) began treatment with two haemodialysis sessions per week, 49 patients (25%) with three haemodialysis sessions per week and 83 patients (43%) with peritoneal dialysis. The glomerular filtration rate was measured as the mean of the renal clearances of urea and creatinine. RESULTS: The rate of decrease in glomerular filtration was the same in patients who began treatment with two haemodialysis sessions per week and with peritoneal dialysis (median 0.18ml/min/month) and it was higher in patients who began treatment with three sessions of haemodialysis per week (median 0.33 ml/min/month, P<.05). Throughout progression, the glomerular filtration rate did not display differences between the group that began with two weekly sessions of haemodialysis and the group on peritoneal dialysis, and it was lower in the group that began treatment with three sessions of haemodialysis per week with statistical significance during the first 24 months of follow up. In the three patient groups, β2- microglobulin concentration increased as the glomerular filtration rate decreased and it was higher in the group on three weekly haemodialysis sessions for the first 12 months of follow up. In all the controls carried out, there was a negative correlation between the β-2 microglobulin concentration and the glomerular filtration rate (P<.001). The erythropoietin dose was negatively related to glomerular filtration. Patients who began with two sessions of haemodialysis per week required a lower dose of erythropoietin than patients that began renal replacement therapy with three weekly sessions. The erythropoietin dose in the peritoneal dialysis group was below that of the group of two weekly haemodialysis sessions despite maintaining a similar glomerular filtration rate. CONCLUSIONS: Patients who begin treatment with two sessions of haemodialysis per week experience the same rate of decrease in residual renal function as patients treated with peritoneal dialysis. The progression of the concentration of β2-microglobulin is parallel to that of the glomerular filtration rate. Patients treated with two haemodialysis sessions require a lower dose of erythropoietin than those who receive three sessions per week, but a significantly higher dose than those treated with peritoneal dialysis, which suggests that the response of anaemia to erythropoietic agents is not only related to residual renal function, but also to other factors that are inherent to the dialysis technique

RESUMO

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)

RESUMO

OBJETIVO: Evaluar de manera prospectiva si la infección post-litotricia por ondas de choque aumenta el daño renal en los pacientes que se trataron por calculos renales con este método.MÉTODOS: Los niveles de LDH, CPK y β2 – microglobulina se midieron en la orina de 171 pacientes con litiasis renal de más de 3 cm antes y despues de la litotricia. Los cambios en los valores de los biomarcadores pre y post litotricia se evaluaron mediante la prueba de X2 para ámbos grupos y se compararon entre los 2 grupos con los valores post-tratamiento.RESULTADOS: A pesar del tratamiento previo con antibioticos el 21,6% de los pacientes presentaron una infeccion post-litotricia. En el grupo de pacientes con orina esteril después de la litotricia hubo un aumento de 5.8, 2.2 y 0.7 veces de los valores de CPK, LDH y β-2 microglobulina respectivamente (p < 0.001), lo que indica un cierto grado de daño renal immediato. En el grupo de los pacientes con infección urinaria post-litotricia el aumento era 80, 15 y 2.2 veces respectivamente mucho mayor del grupo anterior (p<0.001).CONCLUSIONES: La litotricia extracorpórea provoca un daño renal transitorio mayor en pacientes que presentan infección urinaria post-litotricia. La importancia de este hallazgo debe investigarse a largo plazo(AU)


OBJECTIVES: To prospectively assess if urinary tract infection (UTI) after extracorporeal shock wave lithothripsy (ESWL) enhances immediate renal damage in patients with renal stones.METHODS: Levels of lactic dehydrogenase (LDH), crea-tine phosphokinase (CPK), and β2 microglobulin were measured in the urine of 171 patients, before and after ESWL for treatment of up to 3cm renal stones. Standard investigation included urine sample before and after treatment. Patients were divided in two groups in ac-cordance to presence of positive bacterial urine sample after ESWL. Changes in biomarker values pre- and post- ESWL were assessed via X2 test for both groups and compared between the two groups for post-treatment values. RESULTS: Despite pre-treatment antibiotic therapy, 21.6% of the patients presented with UTI after ESWL. In the group with clear post-treatment urine samples there was a 5.8, 2.2, and 0.7 fold increase of CPK, LDH, and β2 microglobulin levels after ESWL, respectively (p<0.001), indicating some degree of immediate renal damage. In patients with UTI, the levels of the enzymes elevated by 80, 15, and 2.2 fold after ESWL, respectively, which represents a significantly increased elevation comparing with the sterile urine group (p<0.001).CONCLUSIONS: ESWL results in transient immediate renal damage, which is exaggerated in patients with persistent or treatment prompted UTI. Long-term importance of this finding must be determined(AU)

RESUMO

La hemodiafiltración en línea proporciona una alta eficacia depurativa de moléculas de mediano y gran peso molecular. Existe consenso sobre la necesidad de conseguir al menos 20 L de ultrafiltración en postdilución y tasas de reducción de B2-microglobulina mayores del 70%. Desafortunadamente muchos pacientes tienen un acceso vascular inadecuado siendo muy difícil lograr esos volúmenes de ultrafiltración sin complicaciones clínicas. El objetivo de este trabajo fue conseguir un volumen de ultrafiltración equivalente a 20 L en postdilucional, mediante la técnica «Secuencial» (HDF-OL-S) que comienza siendo postdilucional y cuando la PTM alcanza los 250 mmHg se trasforma en predilucional. Se realizó una sesión de hemodiálisis de alto flujo (HD-HF), una de hemodiafiltración postdilucional (HDF-OL-P) y otra sesión en modo secuencial a 16 pacientes durante 3 semanas consecutivas, en la sesión de mitad de semana. Se compararon los rendimientos de eliminación de pequeñas y medianas moléculas entre las diferentes técnicas. Se midió la presión prefiltro (PPF) mediante manómetro predializador. No encontramos diferencias en el Kt/V, tasa de reducción de urea y de creatinina entre las3 técnicas. La tasa de reducción de B2-microglobulina y mioglobina fue significativamente mayor tanto en HDFOL-P como en HDF-OL-S con respecto a la HD-HF, no habiendo diferencias entre ambas técnicas de HDF. Existió una correlación directa entre PTM y PPF a lo largo de la sesión en todas las técnicas. La PPF horaria se correlacionaba mejor que PTM con los niveles basales de albúmina sérica, hematocrito y porcentaje de hemoconcentración al final de la diálisis. La HDF-OL-S es una técnica de hemodiálisis con los mismos beneficios de la postdilucional que permite lograr volúmenes de ultrafiltración dentro de los objetivos planteados. Creemos podría ser útil en pacientes con flujos sanguíneos limitados para lo cual habría que diseñar nuevos estudios. La PPF aporta información complementaria a la PTM (AU)


Background: On line haemodiafiltration provides the greatest clearance for low and high-molecular weight uremic toxins, which is associated with a lower risk of mortality in our patients. Nowadays, there’s increasing evidence about the need of achieving at least 20 litters ultrafiltration in postdilution mode and70% reduction of beta-2-microglobulin (B2M), however it requires a vascular access’s high blood flow. Unfortunately, we do not succeed in these objectives because of our patients being older, diabetic and with poor vascular access; in this situation highblood flows are more difficult to get at the expense of lower postdilution exchange volumes. The aim of this study was to assess the efficiency of OL-S-HDF to obtain an equivalent ultrafiltration volume as 20 L in OL-postdilution-HDF (OL-P-HDF). OL-SHD Finitially begins in postdilution mode changing to predilution once the transmembrane pressure (TMP) reached 250 mmHg. Methods: We performed one high-flux HD session (HF-HD), one OL-P-HDF session and one OL-S-HDF session in each of the 16adult patients who participated during 3 consecutive weeks. We compared the clearance rates of low and middle molecules such asurea, creatinine, B2M, myoglobulin and levels of albumin and haematocrit between the 3 different techniques. We measured the pre-filter pressure (PFP) by a manometer set before the dialyzer. Results: The main characteristics of the sessions are described in table Nº1. There wasn¿t significant difference in Kt/V, urea and creatinine removal between the three techniques. B2M and myoglobulin¿s clearance rates were significantly higher in both hemodiafiltration modes than in HF-HD (p = 0.000), however we didn¿t find differences between OL-P-HDF and OL-S-HDF. There was a direct correlation between PFP and TMP along the sessions in every technique (p < 0.05). We found that PFP was better than TMP to correlate with pre-dialysis levels of albumin and haematocrit and also with the haemoconcentration percentage at the end of the sessions. Conclusions: This study confirms that OL-S-HDF is as good as OL-P-HDF and it could be a useful technique to treat patients with suboptimal access¿s blood flow to get to achieve ultrafiltration volumes within the objectives. PFP could offer extra information than TMP (AU)

RESUMO

Antecedentes y objetivos: El sarcoma de Kaposi es la neoplasia más frecuente en pacientes VIII positivos siendo, a veces, una de las primeras manifestaciones del SIDA. Nos proponemos establecer la prevalencia del sarcoma de Kaposi epidémico en nuestros pacientes VIII positivos y analizar sus características clínicas y datos de laboratorio. Material y método: Se han revisado un total de 160 historias clínicas de pacientes VIII positivos de los últimos diez años, controlados en la Unidad VIII del Servicio de Enfermedades Infecciosas del Hospital Militar Gómez-Ulla de Madrid. Se realiza un estudio descriptivo transversal retrospectivo. Se valoraron la edad, sexo, localización de las lesiones, evolución del sarcoma, así como los parámetros de laboratorio: VSG, linfocitos CD4÷, carga viral de VIH por PCR (Amplicor) y f2 microglobulina. Resultados: La prevalencia del sarcoma kaposi fue del 5%, todos varones, siendo la edad media de 45 años. En el 50% fue la primera manifestación de la infección por VIII. En el momento del diagnóstico, las medias de los datos de laboratorio fueron VSG: 44,38 ± 28 mm; Linfocitos CD4+: 210,4 ± 378 cel /jiL; carga viral de VIII: 311400 ± 434983 copias/ml y 32- microglobulina: 3,17 ± 1,28 mg/L. Fallecieron el 62,5% de pacientes, con una supervivencia media de 8,4 meses. Conclusiones: En nuestros pacientes VIH + hemos observado una baja frecuencia de sarcoma de Kaposi. En el momento del diagnóstico presentaban cifras muy elevadas de carga viral, con descenso de linfocitos CD4+ y aumento de VSG y 3z-microglobulina (AU)
