    Los inhibidores adquiridos del factor IX son extremadamente raros. Un hombre de 70 años presentó sangrado profuso continuo luego de una cirugía ortopédica. Su PTT activado inicial fue 77.4 segundos (intervalo normal, 25-36) y su PT fue normal. La corrección del PTT activado expandido, resulta a favor del déficit del factor IX, confirmando el nivel de dicho factor 52%, con niveles normales de factor VIII. Esto fue realizado con plasma fresco congelado. Se presenta una revisión exhaustiva del tema. [Sossa Cl, Jiménez SI, Rodríguez P. Inhibidores contra los factores de la coagulación adquiridos espontáneamente: Hemofilia B adquirida.Acquired factor IX inhibitors are extremely rare. A 70-year-old man presented with continuous profuse bleeding after orthopedic surgery. His initial activated PTT was 77.4 seconds (normal range, 25-36) and his PT was normal. The correction of the expanded activated PTT results in favor of the factor IX deficiency, confirming the level of said factor 52%, with normal levels of factor VIII. This was performed with fresh frozen plasma. An exhaustive review of the topic is presented. [Sossa Cl, Jiménez SI, Rodríguez P.

    La anemia hemolítica autoinmune se asocia con una variedad de virus hepatotrópicos, en particular citomegalovirus (CMV), virus del Epstein-Barr y de la hepatitis B. No es frecuente dentro de la historia natural de la hepatitis A, la aparición de anemia hemolítica, y cuando se presenta, generalmente se asocia a deficiencia de glucosa-6-fosfato deshidrogenasa. Presentamos el caso de un paciente de sexo masculino sin hemólisis previa, con astenia e ictericia de dos meses de evolución y hepatomegalia 14 cm por debajo del reborde costal derecho. Los hallazgos en los exámenes de laboratorios mostraron anemia hemolítica con Coombs directo positivo, anticuerpos tipo inmunoglobulina M contra el virus de la hepatitis A positivos, niveles de bilirrubinas 20 veces y aminotrasferasas cuatro veces por arriba del rango normal; con estos datos el paciente fue diagnosticado como hepatitis A complicada con anemia hemolítica y probable hepatitis autoinmune asociada, por lo que se inició manejo con corticoides, alcanzándose mejoría clínica. Resaltamos la importancia de descartar la infección por el virus de la hepatitis A como posible etiología de anemia hemolítica autoinmune. &nbsp

It is not frequent within the natural history of hepatitis A, the appearance of hemolytic anemia, and when it occurs, it is generally associated with glucose-6-phosphate dehydrogenase deficiency. We present the case of a male patient without previous hemolysis, with asthenia and jaundice for two months and hepatomegaly 14 cm below the right costal margin. Laboratory examination findings showed direct positive Coombs hemolytic anemia, positive immunoglobulin M antibodies against hepatitis A virus, bilirubin levels 20 times and aminotrases four times above the normal range; With these data, the patient was diagnosed as complicated hepatitis A with hemolytic anemia and probable associated autoimmune hepatitis, for which management with corticosteroids was initiated, achieving clinical improvement. We highlight the importance of ruling out hepatitis A virus infection as a possible etiology of autoimmune hemolytic anemia

    Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

The typical course of hepatitis A is rarely complicated with glucose-6-phosphate dehydrogenase deficiency. Wepresent the case of a man without previous haemolysis, he had been unwell for two months with fatigue and jaundice, the liver edge was palpable and tender 14 cm below the costal margin. Clinical chemistry showed haemolytic anaemia with positive direct coombs test, immunoglobulin M antibodies to hepatitis A virus were detected, the total bilirrubin concentration 20 times the upper and transaminase 4 times upper limit for normal levels; with this finds the case was diagnosed hepatitis A complicated by haemolytic anaemia and associated with probable autoimmune hepatitis, therefore was started treatment with corticosteroids, over the following week he gradually improved clinically. We described the importance rule out hepatitis A viral infection as possible etiology for haemolytic anaemia
