ABSTRACT

BACKGROUND: Convalescent plasma is frequently administered to patients with Covid-19 and has been reported, largely on the basis of observational data, to improve clinical outcomes. Minimal data are available from adequately powered randomized, controlled trials. METHODS: We randomly assigned hospitalized adult patients with severe Covid-19 pneumonia in a 2:1 ratio to receive convalescent plasma or placebo. The primary outcome was the patient's clinical status 30 days after the intervention, as measured on a six-point ordinal scale ranging from total recovery to death. RESULTS: A total of 228 patients were assigned to receive convalescent plasma and 105 to receive placebo. The median time from the onset of symptoms to enrollment in the trial was 8 days (interquartile range, 5 to 10), and hypoxemia was the most frequent severity criterion for enrollment. The infused convalescent plasma had a median titer of 1:3200 of total SARS-CoV-2 antibodies (interquartile range, 1:800 to 1:3200). No patients were lost to follow-up. At day 30 day, no significant difference was noted between the convalescent plasma group and the placebo group in the distribution of clinical outcomes according to the ordinal scale (odds ratio, 0.83; 95% confidence interval [CI], 0.52 to 1.35; P = 0.46). Overall mortality was 10.96% in the convalescent plasma group and 11.43% in the placebo group, for a risk difference of -0.46 percentage points (95% CI, -7.8 to 6.8). Total SARS-CoV-2 antibody titers tended to be higher in the convalescent plasma group at day 2 after the intervention. Adverse events and serious adverse events were similar in the two groups. CONCLUSIONS: No significant differences were observed in clinical status or overall mortality between patients treated with convalescent plasma and those who received placebo.

ABSTRACT

We report to simultaneous use of extracorporeal life support (ECLS), plasmapheresis, hemodiafiltration and exogenous surfactant for the treatment of pulmonary hemorrhage, arterial hypertension, and renal failure secondary to nodose polyarteritis (NPA) in a 23-month-old patient. NPA is an autoimmune disease that affects small -and medium- caliber muscular arteries. Hypoxemia refractory to treatment with conventional and high frequency oscillatory ventilation was supported by ECMO while awaiting control of the autoimmune disease through the use of plasmapheresis and immunosuppressive treatment. Although the combination of ECLS with plasmapheresis is rare, it has been described during the management of cases of organ transplant, intoxication, cardiac failure, and sepsis. There are only two previous reports describing the use of this combined therapy for the treatment of pulmonary hemorrhage secondary to autoimmune vasculitis in childhood.

ABSTRACT

Se comunica el caso de un paciente de 23 meses de edad, con hemorragia pulmonar, hipoxemia refractaria, hipertensión arterial y falla renal secundarias a poliarteritis nodosa (PN) que ha requerido asistencia simultánea con soporte cardiopulmonar extracorpóreo (ECMO), plasmaféresis, hemodiafiltración y surfactante exógeno. La PN es una vasculitis autoinmunitaria que afecta los vasos arteriales de pequeño y mediano calibres. La hipoxemia, refractaria al tratamiento con ventilación mecánica convencional y de alta frecuencia oscilatoria, fue sostenida con ECMO mientras se controló la enfermedad autoinmunitaria mediante plasmaféresis y tratamiento inmunosupresor. La combinación de ECMO con plasmaféresis es infrecuente, pero ha sido descripta en relación al trasplante de órganos, intoxicaciones, fallo cardíaco y sepsis. Existen dos casos descriptos en la bibliografía sobre el uso combinado de estas terapéuticas para el tratamiento de hemorragia pulmonar secundaria a vasculitis autoinmunitaria en niños.

ABSTRACT

La presencia del Inhibidor Adquirido de Factor VIII, con una frecuencia poblacional de 1 caso por millón al año, es una patología que puede presentar episodios de sangrados muy graves. Cerca del 50 por ciento de los casos son idiopáticos. En esta presentación se reportan dos casos internaados en nuestra institución entre 2006 y 2007.

ABSTRACT

Presentamos el caso de una puérpera con síndrome HELLP e insuficiencia renal aguda bajo tratamiento hemodialítico y plasmaféresis, que desarrolla síndrome de dificultad respiratoria aguda (SDRA). A la etiología multifactorial vinculada con esta variedad grave de preeclampsia, podrían sumarse otros factores durante la evolución de la enfermedad, que agravarían la injuria pulmonar inicial. Interrumpido el embarazo, otras medidas terapéuticas coadyuvantes deberán considerarse para favorecer la resolución de la lesión respiratoria. El objetivo en la prevención del SDRA es el anjo de los líquidos que deberá guiarse mediante el monitoreo hemodinámico
