Predicting the response to methylprednisolone pulses in patients with SARS-COV-2 infection.

Introduction: Treating systemic inflammation caused by SARS-COV 2 (COVID-19) has become a challenge for the clinician. Corticosteroids have been the turning point in the treatment of this disease. Preliminary data from Recovery clinical trial raises hope by showing that treatment with dexamethasone at doses of 6 mg/day shows a reduction on morbidity in patients requiring added oxygen therapy. However, both the start day or what kind of corticosteroid, are still questions to be clarified. Since the pandemic beginning, we have observed large differences in the type of corticosteroid, dose and initiation of treatment.Our objective is to assess the predictive capacity of the characteristics of patients treated with methylprednisolone pulses to predict hospital discharge. Materials and methods: We presented a one-center observational study of a retrospective cohort. We included all patients admitted between 03/06/2020 and 05/15/2020 because of COVID-19. We have a total number of 1469 patients, of whom 322 received pulses of methylprednisolone. Previous analytical, radiographic, previous disease data were analyzed on these patients. The univariant analysis was performed using Chi-squared and the T test of Student according to the qualitative or quantitative nature of the variables respectively. For multivariate analysis, we have used binary logistic regression and ROC curves. Results: The analysis resulted statistically significant in dyspnea, high blood pressure, dyslipidemia, stroke, ischemic heart disease, cognitive impairment, solid tumor, C-reactive protein (CRP), lymphopenia and d-dimer within 5 days of admission. Radiological progression and FIO2 input are factors that are associated with a worst prognosis in COVID-19 that receive pulses of methylprednisolone. Multivariate analysis shows that age, dyspnea and C-reactive protein are markers of hospital discharge with an area below the curve of 0.816. Conclusions: In patients with methylprednisolone pulses, the capacity of the predictive model for hospital discharge including variables collected at 5 days was (area under the curve) 0.816.

Los datos preliminares del ensayo clínico Recovery alentan esperanza mostrando que con el tratamiento con dexametasona a dosis de 6 mg/día hay una disminución de la morbimortalidad en pacientes que requieren oxigenoterapia añadida. Sin embargo, tanto el día de inicio, o qué tipo de corticosteroide, son todavía preguntas por aclarar. Desde el inicio de la pandemia hemos observado grandes diferencias en cuanto al tipo de corticoide, dosis e inicio de tratamiento.Nuestro objetivo es valorar la capacidad predictiva de las características de los pacientes tratados con bolos de metilprednisolona para predecir el alta hospitalaria. Materiales y métodos: Presentamos un estudio unicéntrico observacional de cohorte retrospectiva. Incluimos a todos los pacientes ingresados entre el 06/03/2020 y el 15/05/2020 por COVID-19. Contamos con un número total de 1469 pacientes, de los cuales 322 recibieron pulsos de metilprednisolona. De estos pacientes se analizaron los datos clínicos, analíticos, radiográficos, enfermedades previas. El análisis univariante se realizó mediante Chi cuadrado y el test t de Student según la naturaleza cualitativa o cuantitativa de las variables respectivamente. Para el análisis multivariante hemos empleado la regresión logística binaria y las curvas ROC. Resultados: En el análisis resultó estadísticamente significativo la disnea, hipertensión arterial, dislipemia, accidente cerebrovascular, cardiopatía isquémica, deterioro cognitivo, tumor sólido, la proteína C reactiva (PCR), linfopenia y d-dímero a los 5 días de ingreso. La progresión radiológica y de aporte de FIO2 son factores que se asocian a peor pronóstico en la COVID-19 que reciben pulsos de metilprednisolona. En el análisis multivariante se observa que la edad, disnea y la proteína C reactiva son marcadores de alta hospitalaria con un área bajo la curva de 0,816. Conclusión: En pacientes con bolos de metilprednisolona, la capacidad del modelo predictivo del alta hospitalaria incluyendo variables recogidas a los 5 días ha sido (Área Bajo la Curva) de 0.816.

Estudio de coste-efectividad del diagnóstico microbiológico de tuberculosis mediante geneXpert MTB/RIF(R) / Cost-effectiveness study of the microbiological diagnosis of tuberculosis using geneXpert MTB/RIF(R)

Introducción/Objetivo: Evaluar mediante un análisis de coste-efectividad la aplicación de una técnica de biología molecular al diagnóstico de tuberculosis frente a la alternativa diagnóstica clásica. Métodos: Se realizó un análisis de coste-efectividad para evaluar la aplicación teórica de un procedimiento de biología molecular que incluye 2 alternativas de una técnica para la detección precoz de Mycobacterium tuberculosis Complex y resistencia a rifampicina (alternativa1: una determinación a pacientes seleccionados; alternativa2: 2 determinaciones a todos los pacientes). Ambas alternativas se compararon con el procedimiento habitual de diagnóstico microbiológico de tuberculosis realizado a 1972 pacientes durante 2008-2012 (microscopia y cultivo). La medida de la efectividad se hizo en QALY y la incertidumbre se trató mediante análisis de sensibilidad univariable, multivariable y probabilístico. Resultados: Para el método habitual se obtuvo un valor de 8.588€/QALY. En la alternativa1 el gasto fue de 8.487€/QALY, mientras que en la alternativa2 el cociente coste-efectivo ascendió a 2.960€/QALY. La alternativa2 fue la de mayor eficiencia diagnóstica, alcanzando una reducción del 75% del número de días que un paciente con tuberculosis permanece sin tratamiento adecuado, así como una reducción del 70% del número de días que un paciente sin tuberculosis permanece ingresado. Conclusión: La aplicación de una técnica microbiológica molecular en el diagnóstico de tuberculosis es sumamente coste-efectiva frente al método habitual. Su introducción en el procedimiento diagnóstico de rutina supondría una mejora en la calidad asistencial de los pacientes al evitar ingresos y tratamientos innecesarios, reflejándose en un ahorro económico al hospital (AU)

Introduction/Objective: To perform a cost-effectiveness analysis of a molecular biology technique for the diagnosis of tuberculosis compared to the classical diagnostic alternative. Methods: A cost-effectiveness analysis was performed to evaluate the theoretical implementation of a molecular biology method including two alternative techniques for early detection of Mycobacterium tuberculosis Complex, and resistance to rifampicin (alternative1: one determination in selected patients; alternative2: two determinations in all the patients). Both alternatives were compared with the usual procedure for microbiological diagnosis of tuberculosis (staining and microbiological culture), and was accomplished on 1,972 patients in the period in 2008-2012. The effectiveness was measured in QALYs, and the uncertainty was assessed by univariate, multivariate and probabilistic analysis of sensitivity. Results: A value of €8,588/QALYs was obtained by the usual method. Total expenditure with the alternative1 was €8,487/QALYs, whereas with alternative2, the cost-effectiveness ratio amounted to €2,960/QALYs. Greater diagnostic efficiency was observed by applying the alternative2, reaching a 75% reduction in the number of days that a patient with tuberculosis remains without an adequate treatment, and a 70% reduction in the number of days that a patient without tuberculosis remains in hospital. Conclusion: The implementation of a molecular microbiological technique in the diagnosis of tuberculosis is extremely cost-effective compared to the usual method. Its introduction into the routine diagnostic procedure could lead to an improvement in quality care for patients, given that it would avoid both unnecessary hospitalisations and treatments, and reflected in economic savings to the hospital (AU)

[Economic impact of the introduction of a technique for early detection of Mycobacterium tuberculosis Complex in clinical samples in a Spanish hospital]. / Impacto económico de la introducción de una técnica de detección precoz de Mycobacterium tuberculosis Complex en las muestras clínicas de un hospital español.

BACKGROUND: Tuberculosis (TB) remains an important public health problem worldwide. Our objective was to estimate the economic and health care impact of the introduction of an early diagnosis tecnique of TB, the Xpert MTB/RIF® assay (Xpert). METHODS: The savings was estimated on the basis of reduction in the time of TB hospitalization at avoid the false-negative (FN) and false-positive (FP) TB cases diagnosed by auramine staining that could have been detected by Xpert between 2008-2012 in our hospital. The costs analysis was made by adding the cost arising from FN (hospitalization, special tests and equipment for respiratory isolation) and FP (TB treatment, successive medical consultations, analytical and microbiological controls). RESULTS: We detected 19 FP and 22 FN during the 5-year study. Xpert would have detected 19 FP and 15 FN. It was estimated a minimum cost of 3217 euros per FP (treatment, successive medical consultations, analytical and microbiological controls), while each FN has required an extension of hospitalization from 7 days on average (62229 euros), both translated into a global cost of 62229 euros. After an initial investment of 16250 euros (50 cases with high suspicion of TB at 65 euros/test), the hospital would have saved 45979 euros overall in five years. CONCLUSIONS: The introduction of Xpert would improve the quality of health care of patients, avoiding both unnecessary hospitalizations and treatments. Also, Xpert carries a saving for our hospital.

Fundamentos: La tuberculosis (TB) continúa siendo un problema importante de salud pública a nivel mundial. El objetivo del estudio fue estimar el impacto económico y asistencial de la introducción de Xpert MTB/RIF® (Xpert), técnica de diagnóstico rápido de TB. Métodos: Se estimó el ahorro en base a la reducción del tiempo de ingreso por TB al evitar los falsos negativos (FN) y falsos positivos (FP) de la baciloscopia que se habrían detectado por Xpert en el periodo 2008-2012. El análisis y cálculo de gastos se hizo sumando el coste de los FN (estancias más pruebas especiales y aislamiento respiratorio) y los FP (tratamiento antituberculoso, consultas sucesivas, analíticas y controles microbiológicos). Resultados: Durante los 5 años de estudio se detectaron 19 FP y 22 FN. Xpert habría detectado los 19 FP y 15 FN. El gasto mínimo estimado para los FP fue de 3.217 euros (tratamiento, consultas sucesivas, analíticas y controles microbiológicos), mientras que cada FN supuso una prolongación de una estancia media de 7 días (59.012 euros), traducidos ambos en un coste total de 62.229 euros. Con una inversión inicial de 16.250 euros (50 casos con elevada sospecha de TB a 65 euros/prueba) el hospital habría ahorrado un global de 45.979 euros en 5 años. Conclusión: La introducción de Xpert supondría un ahorro económico para el hospital y una mejora en la calidad asistencial, evitando estancias y tratamientos innecesarios(AU)

[Effect of Helicobacter pylori eradication on iron deficiency anemia of unknown origin]. / Efecto de la erradicación de Helicobacter pylori en la anemia ferropénica de origen incierto.

UNLABELLED: Iron deficiency anemia of unknown origin is a frequent cause of anemia in which etiological diagnosis is often not achieved, despite currently available diagnostic techniques. Recent studies suggest that, in the absence of digestive tract lesions, Helicobacter pylori infection could be the cause of iron deficiency anemia, due to the alterations produced in gastric iron absorption. OBJECTIVES: To evaluate whether H. pylori eradication resolves iron deficiency anemia and removes the need for oral iron administration. PATIENTS AND METHODS: We performed an observational descriptive study in patients with iron deficiency anemia refractory to treatment with oral iron administration and with out causes that could explain their anemia. Gastroscopy, ileocolonoscopy, intestinal transit study and/or endoscopic capsule were performed. Female patients also underwent gynecological study. All patients were H. pylori-positive and standard eradication therapy was administered until elimination was achieved. The patients were followed-up for a minimum of 3 months after H. pylori eradication and the need for oral iron intake after eradication was evaluated. RESULTS: Ten patients, aged 53+/-8.2 years, were included. Hemoglobin (Hbg) before treatment was 10.06+/-0.53 mg/dl, mean corpuscular volume (MCV) was 75.43+/-6.02 fl and ferritin was 6.1+/-3.28 ng/ml. Eradication therapy was administered until elimination of H. pylori. The mean time before disappearance of anemia was 4.5 months. Laboratory parameters after treatment were as follows: Hgb 12.86+/-0.75 mg/dl, MCV 85.02+/-4.8 fl and ferritin 28+/-22.19 ng/dl. CONCLUSIONS: In the absence of lesions that could explain iron deficiency anemia, this disease can be related to H. pylori infection. Eradication of this infection is closely followed by disappearance of anemia and ferropenia.

Efecto de la erradicación de Helicobacter pylori en la anemia ferropénica de origen incierto / Effect of Helicobacter pylori eradication on iron deficiency anemia of unknown origin

La anemia ferropénica (AF) de origen incierto es una causa frecuente de ferropenia. A pesar de las técnicas disponibles en la actualidad, no se llega a establecer su diagnóstico etiológico. Recientes estudios sugieren que la infección por Helicobacter pylori podría ser causa de AF en ausencia de lesiones del tracto digestivo, debido a la alteración que se produce en la absorción gástrica de hierro. Objetivos: Evaluar si la eliminación de H. pylori consigue la desaparición de la AF y suprime la necesidad del consumo de hierro oral. Pacientes y métodos: Estudio observacional descriptivo, en el que se han incluido pacientes con AF refractaria al tratamiento con hierro oral y sin causas que la justifiquen. Se realizó una gastroscopia, una ileocolonoscopia, un tránsito intestinal y/o una cápsula endoscópica, así como un estudio ginecológico a las mujeres. Todos los pacientes presentaban H. pylori positivo, por lo que se realizó un tratamiento erradicador estándar hasta su eliminación. Se hizo un seguimiento mínimo de 3 meses tras la eliminación de H. pylori y se valoraron las necesidades de hierro oral tras la erradicación. Resultados: Se incluyó a 10 pacientes con una media ± desviación estándar de edad de 53 ± 8,2 años. La hemoglobina (Hb) antes del tratamiento era de 10,06 ± 0,53 mg/dl, el volumen corpuscular medio (VCM) de 75,43 ± 6,02 fl y la ferritina de 6,1 ± 3,28 ng/ml. Se llevó a cabo un tratamiento erradicador hasta la desaparición de H. pylori. El tiempo medio hasta la desaparición de la anemia fue de 4,5 meses. Los parámetros analíticos tras el tratamiento fueron: Hb 12,86 ± 0,75 mg/dl, VCM 85,02 ± 4,8 fl y ferritina 28 ± 22,19 ng/dl. Conclusiones: La AF de origen incierto, en ausencia de lesiones que la justifiquen, puede relacionarse con la infección por H. pylori. La eliminación de esta infección se sigue a corto plazo con la desaparición de la anemia y de la ferropenia
