RESUMO

Fundamento: en la insuficiencia renal crónica terminal, tratamientos como la hemodiálisis inducen cambios sustanciales en el estilo de vida. Los tratamientos se dirigen a lograr la mejoría funcional mediante la reducción de síntomas y/o el enlentecimiento de la progresión de la enfermedad. Objetivo: evaluar la calidad de vida relacionada con la salud de los pacientes en hemodiálisis periódica intermitente. Métodos: se realizó un estudio descriptivo, transversal, en pacientes con insuficiencia renal crónica con tratamiento de hemodiálisis periódica en el servicio de hemodiálisis y diálisis peritoneal del Hospital Militar Dr. Carlos J. Finlay durante el periodo de enero a febrero del año 2013. Para evaluar la calidad de vida relacionada con la salud, se utilizó el instrumento Kidney Disease Quality of Life Short Form versión 1.3. Resultados: las dimensiones genéricas de menores puntuaciones fueron el rol físico, la percepción general de salud y el rol emocional. Las dimensiones específicas con menores puntuaciones fueron la carga de la enfermedad renal, el estatus laboral y la función sexual y las dimensiones con mayores puntuaciones fueron las específicas: relación con el personal de diálisis (85,62 puntos), función cognitiva (84,33 puntos) y calidad de la relación social (82,88 puntos). Conclusión: al igual que en otros países, en Cuba el KDQOL-SF permite evaluar la calidad de vida relacionada con la salud en el paciente en hemodiálisis periódica intermitente, pues permite identificar de manera efectiva las dimensiones y esferas más afectadas en estos.


Background: in end-stage chronic renal failure, treatments like hemodialysis induce substantial changes in lifestyle. Such therapies aim to achieve functional improvement by reducing symptoms and/or slowing disease progression. Objective: to evaluate the health-related quality of life in patients undergoing regular hemodialysis. Methods: a cross-sectional study was conducted in chronic renal failure patients undergoing regular hemodialysis in the hemodialysis and peritoneal dialysis service of the Dr. Carlos J. Finlay Military Hospital from January through February 2013. The Kidney Disease Quality of Life Short Form version 1.3 was used to evaluate the health-related quality of life. Results: generic dimensions with lower scores were the physical role, general health perception and emotional role. The specific dimensions with lower scores were the burden of kidney disease, employment status and sexual function while dimensions with higher scores were specific: relationship with the dialysis staff (85.62 points), cognitive function (84.33 points) and quality of social relationship (82.88 points). Conclusion: As in other countries, the KDQOL-SF enables the evaluation of health-related quality of life in regular hemodialysis patients in Cuba, since it allows effectively identifying the dimensions and areas most affected.

RESUMO

BACKGROUND: The progressive decline in the immune function during ageing is termed immunosenescence. Previous studies have reported differences between males and females in the distribution and cell responses of lymphocyte subsets. Most studies of immunosenescence have been done in populations of industrialized countries living in a rather cold environment, and facing lower antigenic challenges such as Cytomegalovirus (CMV). The aim of this study was to determine the effect of ageing on lymphocytes in a population with a high prevalence of CMV infection in all ages, and to compare gender differences related to the immunosenescence markers. RESULTS: Different populations of peripheral blood leukocytes from healthy young and old IgG-CMV seropositive individuals were examined using flow cytometry. With age, the number and frequency of B cells and T cells significantly decreased, while highly differentiated T cells increased. Such changes were different in males and females. The age-associated decline of less differentiated lymphocyte subsets (CD19, CD4 and CD8 cells) and the increase of highly differentiated T cells were more prominent in females. In males, there were no significant changes in CD19, CD4 and CD8 subsets but there was a significant increase in the proportion of highly differentiated T cells. CONCLUSION: Shifts in lymphocyte subsets distribution were influenced by age and gender in an IgG-CMV seropositive population. These results suggest different patterns of immunosenescence in respect to gender differences. These patterns could have implications in the design of immunotherapy in the elderly.

RESUMO

Epidermal Growth Factor (EGF) promotes tumor cell proliferation and survival uponbinding to its receptor. We have developed a new active specific immunotherapy based on EGF deprivation. In the present paper, we show the results of a Phase I trial in 43patients with advanced non-small cell lung cancer (NSCLC) who received the EGF vaccine. Patients who had already received first line therapy were randomized to receive a singleor double dose of the EGF vaccine, weekly for four weeks and monthly thereafter. No significant toxicity was seen after vaccination. Adverse events consisted primarily of fever,chills, nausea, vomiting and flushing. Fifteen patients (39percent) developed a good antibody response (GAR) against EGF. The geometric mean of the antibody titer was higher in thedouble dose group. EGF concentration was quantified in serum. An inverse correlation between anti-EGF antibody titers and EGF concentration was seen after immunization. Vaccinated patients achieved median survival times of 8.23 months from randomization. Patients who received the double dose of treatment showed a trend toward increased survival in comparison with patients who received the single dose. GAR and patients in whom the serum EGF decreased below the 168 pg/ml cut-off point had a significantly better survival when compared to poor responders or patients in which the EGF levels were not considerably reduced. Our results confirm the immunogenicity of the EGF vaccine in the treatment of patients with advanced stage NSCLC. Antibody titers and serum EGF levels appear to correlate with patient survival(AU)


Factor de Crecimiento Epidérmico (FEAG) promueve la proliferación celular tumoral y la supervivencia a unión a su receptor. Hemos desarrollado un nuevo principio activo basado en la inmunoterapia específica sobre la privación FEAG. En el presente trabajo, mostramos los resultados de un ensayo fase I en 43 pacientes con avanzado de células no pequeñas de cáncer de pulmón (CPNM) que recibieron la vacuna contra el FEAG. Los pacientes que ya habían recibido terapia de primera línea fueron asignados aleatoriamente a recibir un solo o doble dosis de la vacuna contra el FEAG, la semana durante cuatro semanas y mes. No toxicidad significativa fue visto después de la vacunación. Los eventos adversos se componía fundamentalmente de fiebre, escalofríos, náuseas, vómitos y enrojecimiento. Quince pacientes (39 por ciento) desarrollaron un buen anticuerpo respuesta (GAR) contra FEAG. La media geométrica de los anticuerpos fue mayor en el dosis doble grupo. FEAG se cuantificó la concentración en el suero. Una correlación inversa entre la lucha contra la FEAG los títulos de anticuerpos y FEAG concentración fue visto después de la vacunación. Pacientes vacunados alcanzado los tiempos medios de supervivencia de 8,23 meses desde la aleatorización. Los pacientes que recibieron la dosis doble de tratamiento mostraron una tendencia hacia un mayor la supervivencia en comparación con los pacientes que recibieron la dosis única. GAR y los pacientes en los cuales el suero FEAG disminuyó por debajo de los 168 pg / ml punto de corte tenía una significativa una mejor supervivencia en comparación con los pobres o los pacientes con respuesta en la que el FEAG niveles no se redujo considerablemente. Nuestros resultados confirman la inmunogenicidad de la vacuna contra el FEAG en el tratamiento de pacientes con CPNM avanzado. Los títulos de anticuerpos en suero y FEAG niveles parecen correlacionarse con la supervivencia de los pacientes
