Construction of a coagulation prediction model of the extracorporeal circulation circuit during hemodialysis with regional citrate anticoagulant (RCA)
Research article published in The International journal of artificial organs (2024)
Abstract
OBJECTIVE: To construct a prediction model of coagulation in the extracorporeal circulation circuit during hemodialysis with regional citrate anticoagulant(RCA) conditions. METHODS: This was a single-center, retrospective study. The clinical data of patients who received hemodialysis with RCA from February 2021 to March 2022 were collected. The risk predictors of coagulation in the extracorporeal circulation circuit were screened by LASSO regression. On this basis, we used multivariate logistic regression analysis to establish a nomogram prediction model. RESULTS: A total of 98 patients received RCA hemodialysis for 362 times. Among them, 155 treatments with complete data were included in the study. Among the 155 treatments, coagulation of the extracorporeal circulation circuit occurred 12 times. The use of arteriovenous fistulas(AVF), the venous pressure at 4 h after hemodialysis initiation, blood flow velocity, dialyzer manufacturer, Systemic iCa2+ at 1 h after hemodialysis initiation, plasma albumin level, and plasma d-dimer level were influencing factors of coagulation in the extracorporeal circuit during hemodialysis with RCA (p < 0.05). A nomogram model was made out of the above indicators. The area under the receiver operating characteristic (ROC) curve for predicting coagulation in the circuit was 0.967 (95% CI: 0.935-0.998). The internal validation result of the memory testing (bootstrap method) showed that the area under the ROC curve was 0.967 (95% CI: 0.918-0.991). CONCLUSION: The nomogram model has good discrimination and calibration and can intuitively and succinctly predict the risk of coagulation in the extracorporeal circulation circuit during hemodialysis with RCA.

Por qué esto importa para la hirudoterapia
Este estudio retrospectivo unicéntrico utilizó LASSO y regresión logística multivariada para construir un nomograma que predice la coagulación del circuito extracorpóreo durante la hemodiálisis bajo anticoagulación regional con citrato, basándose en 155 tratamientos completados (en los que la coagulación del circuito ocurrió 12 veces) e identificando factores como el tipo de acceso, la presión venosa tras el inicio, la velocidad del flujo sanguíneo, el dializador, el calcio ionizado, la albúmina y el dímero-d, con un área reportada bajo la curva ROC de 0.967. Su relevancia para la hirudoterapia es contextual más que directa: ilustra el problema clínico persistente de controlar la coagulación extracorpórea y local, la misma biología de la coagulación sobre la que actúan la hirudin de la sanguijuela y otros anticoagulantes salivales, y refuerza por qué las estrategias anticoagulantes robustas siguen siendo una prioridad de investigación. Advertencia honesta: este es un estudio pequeño, unicéntrico y retrospectivo de modelado predictivo con solo 12 eventos de resultado y únicamente validación interna; no involucra ningún producto de sanguijuela y el alto AUC no ha sido validado externamente, por lo que no debe interpretarse como evidencia sobre la hirudoterapia.
