Evaluation of Pleural Fluid Lactate for Diagnosis and Management of Parapneumonic Pleural Effusion.

BACKGROUND: The aim was to measure the accuracy of pleural fluid lactate concentration for diagnosis of parapneumonic pleural effusion (PPE) and to discriminate between uncomplicated (UPPE) and complicated PPE (CPPE). METHODS: Pleural fluid lactate was measured in patients with pleural effusion. Patients were classified into two groups according to the etiology of pleural effusion: PPE and NOT PPE. RESULTS: We studied 173 patients. Thirty patients were PPE (10 UPPE and 20 CPPE) and 143 were NOT PPE. The AUC value was 0.831 (p < 0.0001) and the optimal cutoff value was 5.6 mmol/L exhibiting 70% sensitivity and 90.9% specificity for diagnosis of PPE. Also, pleural fluid lactate could be used to discriminate between UPPE and CPPE, the AUC value was 0.740 (p = 0.0089) and the optimal cutoff value was 10.2 mmol/L, exhibiting 45% sensitivity and 90% specificity. CONCLUSIONS: Pleural fluid lactate has a high accuracy for diagnosis and management of PPE.

Advanced chronic renal failure (ACRF) study. Baseline characteristics, evaluation of the application of the structured information for the election of renal replacement therapy and one-year evolution of the incident patients in the ACRF medical office. / Estudio ERCA. Características basales, evaluación de la aplicación de la información estructurada para la elección de tratamiento renal sustitutivo y evolución a un año de los pacientes incidentes en la consulta ERCA.

BACKGROUND AND OBJECTIVES: Analyze evolution Renal Chronic Failure stage 4-5 (ACRF) patients and influence information they receive (educational process, EP) in modality Renal Replacement Therapy (RRT) or conservative treatment (CT) in multidisciplinar ACRF Office. MATERIAL AND METHODS: Prospective, multicenter study (3 centers). Inclusion: from June-01-2014 to October-01-2015; observation: 12 months or until start RRT or death if they occur before 12 months; ends October-01-2016. RESULTS: 336 patients were included (60% males), median and intercuartile rank 71.5 (17), 55% ≥ 70 years; Follow up initiation eGFR CKD-EPI: 21 (9) ml / min / 1.73m2; Charlson Index (ChI) with / without age 8 (3) / 4 (2); Diabetic patients: 52,4%. The EP was carried out in 168, eGFR 15 (10) ml / min / 1.73m2. The initial treatment election: 26% peritoneal dialysis (PD), 45% hemodyalisis (HD), 26% CT, kidney trasplant 3%; 60 patients started RRT: 3.3% kidney traspant; 30% PD, 66% HD; 104 admissions in 73 patients, the most frequent cause: cardiovascular disease (42%). Fallecimiento: 23 patients (6.8%). Age was higher (78.4 (6) vs. 67.8 (13.4), P<.001), higher ChI 9.8 (2.1) vs. 7.4 (2.5), P<.001). All deceased who received EP had chosen CT; 61% of deceased had at least one hospital admission vs. 39% alive (P<0.001). Cox regression: age and Charlson index were the predictive mortality variables. CONCLUSIONS: The population of ACRF patients is elder, comorbid, with high rate hospitalizations rate. The PD election is higher than usual. The EP has been very useful tool and has favored the PD choice.

Pleural fluid cell-free DNA in parapneumonic pleural effusion.

OBJECTIVES: To measure the accuracy of pleural fluid cell-free DNA (cfDNA) concentration for diagnosis of parapneumonic pleural effusions (PPE). DESIGN AND METHODS: We studied pleural fluids obtained by thoracocentesis in patients with pleural effusion. DNA was automatically extracted from pleural fluid using the MagNa Pure Compact instrument (Roche Diagnostics), and was measured by a real-time quantitative PCR assay for the ß-globin gene using a Light-Cycler 480 Real-Time PCR instrument (Roche Diagnostics). Patients were classified into two groups according to the etiology of pleural effusion: PPE and NOT PPE. The diagnostic accuracy was determined using receiver operating characteristic (ROC) techniques by analyzing the area under the ROC curve (AUC). RESULTS: We studied 78 patients with ages between 1 and 86 years old (median=64). Sixteen patients were PPE and 62 were NOT PPE (24 transudative, 30 malignant and 8 other etiology). Pleural fluid cfDNA concentration was higher in patients with PPE (median=46,240 ng/mL) than in those with NOT PPE (median=224 ng/mL). The AUC value was 0.907 (p<0.0001) and the optimal cut-off value was 6740 ng/mL exhibiting 87.5% sensitivity and 80.6% specificity. Also, there were significant differences between transudative and exudative effusions according to pleural fluid cfDNA concentration (p<0.0001). The AUC value was 0.994 and the optimal cut-off value was 162ng/mL exhibiting 100% sensitivity and 96.3% specificity. CONCLUSIONS: Pleural fluid cfDNA concentration showed high accuracy for diagnosis of PPE and to discriminate between transudative and exudative effusions.

ANTECEDENTES Y OBJETIVOS: Conocer evolución de pacientes ERC estadios 4 y 5 (ERCA) e influencia de la información (proceso educativo [PE]) que reciben para elección de la modalidad de tratamiento renal sustitutivo (TRS) o tratamiento conservador (TC) en consulta multidisciplinar de ERCA. MATERIAL Y MÉTODOS: Estudio prospectivo, multicéntrico (3 centros españoles). Pacientes incidentes: consulta ERCA desde el 1 de junio del 2014 al 1 de octubre del 015; observación: 12 meses o inicio del TRS o fallecimiento si antes de los 12 meses; finaliza el 1 de octubre del 2016. RESULTADOS: Trescientos treinta y tres pacientes (60% varones), mediana y rango intercuartil: edad 71,5 (17) años (55% ≥ 70 años), FGe CKD-EPI inicio 21 (9) ml/min/1,73 m2, índice de Charlson (ICh) con/sin edad 8 (3)/4 (2). Pacientes diabéticos: 52,4%. Recibieron PE 168 pacientes, FGe al inicio 15 (10) ml/min/1,73 m2. Tratamiento inicial elegido: 26% diálisis peritoneal (DP), 45% hemodiálisis (HD), 26% TC, trasplante renal 3%; 60 pacientes iniciaron TRS: 3,3% trasplante renal, 30% DP, 66% HD. Ingresos: 104 en 73 pacientes, la causa más frecuente fue por enfermedad cardiovascular (42%). Fallecimiento: 23 pacientes (6,8%), de mayor edad (78,4 [6] vs. 67,8 [13,4], p < 0,001), ICh más elevado 9,8 [2,1] vs. 7,4 [2,5], p < 0,001). Todos los fallecidos con PE habían decidido TC; el 61% de los fallecidos tenían al menos un ingreso hospitalario vs. 39%vivos (p < 0,001). Regresión Cox: variables predictivas mortalidad: edad e ICh. CONCLUSIONES:La población de ERCA es añosa, comórbida y con elevado índice de ingresos hospitalarios. La incidencia de DP es mayor a la habitual. El PE ha sido una herramienta de gran utilidad y favorece la elección de DP
