ABSTRACT

Background: The prevalence of low- turnover bone disease (LTBD) in peritoneal dialysis (PD) patients is higher than in hemodialysis (HD) patients. LTBD patients may be at risk for vascular calcification, and cardiovascular disease. Current therapy for chronic kidney disease metabolic bone disorders (CKD-MBD) is guided by biochemical parameters, as bone biopsy is not used in routine clinical care. Methods: We assessed intact PTH (iPTH: 1-84PTH plus non-1-84PTH), 1-84PTH, and the 1-84PTH/non-1-84PTH ratio in 129 hemodialysis and 73 PD prevalent patients dialyzed with solutions containing 1.75 mmol/L calcium. Results: Hemodialysis and PD patients presented similar iPTH and tCa values and prevalence of putative LTBD as defined according to KDOQI iPTH cut-off levels or 1-84 PTH levels. However, iCa accounted for a higher percentage of tCa in PD (53%) than in hemodialysis (39%) p < 0.001, and the 1-84PTH/non-1-84PTH ratio was lower in PD than in hemodialysis patients (0.44 ± 0.12) vs. (0.60 ± 0.10), p < 0.001. The prevalence of putative LTBD when using the coexistence of 1-84PTH/non-1-84PTH ratio < 1.0 and iPTH < 420 pg/m, was higher in PD than in hemodialysis patients (73 vs. 16% respectively, p < 0.001). In a multivariate logistic regression analysis, dialysis modality was the main determinant of the 1-84PTH/non-1-84PTH ratio. Conclusion: Solutions containing 1.75 mmol/L calciums are associated to a higher proportion of non-1-84PTH fragments in PD than in HD patients. Different analytical criteria result in widely different estimates of LTBD prevalence, thus impairing the ability of clinicians to optimize therapy for CKD-MBD.

ABSTRACT

Las complicaciones derivadas de la alteración del metabolismo óseo-mineral tienen un gran impacto sobre los pacientes con enfermedad renal crónica terminal. El arsenal terapéutico usado para prevenir y resolver estas complicaciones ha evolucionado. Estos fármacos –entre otros– son supervisados o administrados por el personal de enfermería. Los profesionales de enfermería tienen una importante labor de educación sanitaria y su conocimiento puede ayudar a aclarar las dudas de los pacientes y mejorar su adherencia terapéutica. El objetivo de este estudio ha sido valorar el grado de conocimiento que los profesionales de enfermería nefrológica tienen de los fármacos utilizados en la corrección de las alteraciones del metabolismo mineral que administran o supervisan en la sesión de diálisis. Se realizó un estudio descriptivo observacional mediante una encuesta de seis preguntas relacionadas con variables sociodemográficas y ocho tipo test, realizada en el XXXV Congreso Nacional de la SEDEN. Fueron entrevistados 72 profesionales. El 36% desempeñaba su labor en Unidades Periféricas. Sólo el 43 % trabajaba en centros donde se administraba medicación oral relacionada con el fósforo: 57% en el caso de los centros hospitalarios frente al 9% de los centros periféricos (p=0,002). La puntuación media, sobre un máximo de 8 puntos, fue de 3,32. Solamente el 17% respondió acertadamente los 2/3 de las preguntas. No existió relación entre la puntuación obtenida y la edad de los encuestados, aunque los encuestados mayores de 44 años (p=0.062) presentan puntuaciones más bajas. La puntuación obtenida por los profesionales de centros hospitalarios (3,41± 2,03) fue ligeramente superior a la obtenida por los profesionales de centros periféricos (3,15 ± 2,22) aunque sin significación estadística (p=0,62). Tampoco encontramos asociación entre el tiempo como profesionales de enfermería, el tiempo desempeñado en unidades de diálisis y la puntuación obtenida. Como conclusión podemos decir que son pocos los centros de diálisis que administran quelantes durante las sesiones, y que hay que mejorar sustancialmente la información sobre estos medicamentos que supervisa y administra enfermería y sobre los que los pacientes reclaman ayuda en forma de información (AU)


The complications deriving from the alteration of the bone mineral metabolism have a considerable impact on patients with terminal chronic renal disease. The therapeutic weapons used to prevent and overcome these complications have evolved. These drugs –among others– are supervised or administered by nursing staff. Nurses have an important health education task and their knowledge can help to clear up patients’ doubt and improve their adherence to treatment. The aim of this study was to evaluate the degree of knowledge that nephrology nursing professionals have of the drugs used in the correction of mineral metabolism alterations administered or supervised by them in the dialysis session. An observational descriptive study was carried out using a survey comprising six questions related to socio-demographic variables and eight multiple choice questions, drawn up in the 35th National Congress of SEDEN. A total of 72 professionals were interviewed. Of these, 36% worked in Peripheral Units. Only 43% worked in centres where oral medication related to phosphorous was administered: 57% in the case of hospitals compared to 9% in the peripheral centres (p=0.002). The mean score, out of a maximum of 8 points, was 3.32. Only 17% answered 2/3 of the questions correctly. There was no relationship between the score obtained and the age of the interviewees, although interviewees aged over 44 (p=0.062) had lower scores. The score obtained by professionals in hospitals (3.41± 2.03) was slightly higher than the score obtained by professionals from peripheral centres (3.15 ± 2.22) although not statistically significant (p=0.62). Nor did we find an association between the time in the nursing profession, the time spent in dialysis units and the score obtained. As a conclusion we can state that there are few dialysis centres that administer chelants during sessions, and substantial improvement is needed in relation to information on these medications which are supervised and administered by nursing staff and on which patients request help in the form of information (AU)
