ABSTRACT

Resumen: La trombocitopenia inducida por heparina es una entidad clínica infrecuente; sin embargo, la amplia y masiva utilización de anticoagulantes en épocas de pandemia por COVID-19 pone de manifiesto una realidad evidente a la cual no podemos escapar. Presentamos el caso de un paciente masculino en la sexta década de vida con SARS-CoV-2, quien luego de la administración de heparina en el escenario de una enfermedad pulmonar tromboembólica desarrolló consumo plaquetario asociado a presencia de anticuerpos antifactor de agregación plaquetaria 4.


Abstract: Heparin-induced thrombocytopenia is an uncommon clinical entity, however the wide and massive use of anticoagulants in times of pandemic by COVID-19 reveals an evident reality and we can not escape. we present the case of a male patient in sixth decade of life with SARS-CoV-2 who after the administration of heparin in the clinical setting of thromboembolic lung disease development platelet consumption associated with the presence of antibodies anti platelet activating factor 4.


Resumo: A trombocitopenia induzida por heparina é uma entidade clínica rara, no entanto, a ampla e massiva utilização de anticoagulantes em tempos de pandemia de COVID-19 revela uma realidade óbvia à qual não podemos fugir. Apresentamos o caso de um doente do sexo masculino na sexta década de vida com SARS-CoV-2 que, após administração de heparina no contexto de doença pulmonar tromboembólica, desenvolveu consumo de plaquetas associado à presença de anticorpos anti-fator de agregação plaquetária 4.

ABSTRACT

Resumen: Presentamos el caso clínico de una paciente de 59 años de edad con sepsis por neumonía polimicrobiana con aislamientos virales condicionantes de sobreinfección bacteriana y trombosis. Su escanografía de tórax reportó colapsos posterobasales con atelectasias e infiltrados intersticiales reticulares; evolucionó con deterioro cognitivo relacionado con enfermedad cerebro vascular multiinfarto documentado por tomografía cerebral con emisión de fotón único por medicina nuclear debido a estudios de cráneo normales; ante la evolución neurológica se realizaron estudios de extensión con ecocardiograma Doppler dúplex color transtorácico, el cual fue normal, así como estudio contrastado de cuatro vasos de cuello, Holter de ritmo eléctrico y perfil metabólico completo también normales. Realizamos una revisión en la literatura con miras a brindar entendimiento y evidenciar la relación directa entre síndromes sépticos e infecciones virales con diferentes estados de hipercoagulabilidad, inflamación y apoptosis.


Abstract: We present the clinical case of a 59-year-old patient with sepsis due to polymicrobial pneumonia with viral isolates conditioning bacterial infection and thrombosis. His chest scannography reported basals collapses with atelectasis and reticular interstitial infiltrates; Evolved with cognitive impairment related to multi-infarction vascular brain disease documented by single-photon emission brain tomography by nuclear medicine due to normal scannographies studies; Given the neurological evolution, extension studies were carried with transthoracic duplex Doppler echocardiogram which was normal, as well as a contrasted study of four neck vessels, electrical rhythm holter and complete metabolic profile also normal. We conducted a review in the literature with a view to providing understanding and evidence of the direct relationship between septic syndromes and viral infections with different states of hypercoagulability, inflammation and apoptosis.


Resumo: Apresentamos o caso clínico de um paciente de 59 anos com sepse por pneumonia polimicrobiana com isolados virais condicionando superinfecção bacteriana e trombose. Sua cintilografia de tórax relatou colapsos póstero-basais com atelectasia e infiltrados intersticiais reticulares; Evoluiu com deterioração cognitiva relacionada à doença cerebrovascular multi-infarto documentada por tomografia cerebral com emissão de fóton único pela medicina nuclear devido a estudos de crânio normais; dada a evolução neurológica, realizaram-se estudos de extensão com ecocardiograma Doppler colorido transtorácico duplex, que foi normal, bem como estudo contrastado de quatro vasos do pescoço, Holter de ritmo elétrico e perfil metabólico completo, também normais. Realizamos uma revisão da literatura com o objetivo de compreender e evidenciar a relação direta entre síndromes sépticas e infecções virais com diferentes estados de hipercoagulabilidade, inflamação e apoptose.

ABSTRACT

Objective To study the dynamic changes and clinical significance of D-D, t-PA and PAI in patients with acute renal failure during the process of different methods of blood purification. Methods Thirty-seven ARF patients were divided into three groups: HD group, HDF group and HF group. Plasma D-D level, t-PA and PAI activity were determined 1 hour, 4 hours before and after treatment. Normal control group consisted of fourteen healthy people. Results ① Plasma D-D level and PAI activity in ARF patients were obviously higher than those in control group, while t-PA activity was lower(P0.05). ③ After 4 hours of the treatment, compared with HD group, HDF and HF groups had significant difference in plasma D-D level, t-PA and PAI activity(P
