ABSTRACT

RESUMEN Las alteraciones hematológicas son comunes en los pacientes con lupus eritematoso sistémico (LES). Pueden expresarse relacionadas con el compromiso de las líneas celulares y con la presencia de alteraciones de la coagulación. El compromiso en la coagulación se asocia con manifestaciones trombóticas. Se han descrito factores de riesgo asociados a trombosis, como la presencia de niveles elevados de homocisteína, déficit adquirido de la proteína S, proteína C y antitrombina. Sin embargo, la diátesis hemorrágica también se ha descrito con menor frecuencia y relacionada con el déficit de factores de la coagulación, secundaria a la presencia de inhibidores. Presentamos 3 pacientes con LES juvenil con manifestaciones hematológicas poco usuales y revisión de la literatura relacionada. Se concluye que las manifestaciones hematológicas en LES juvenil no solo se relacionan con alteraciones en las líneas celulares. Trombosis vasculares y trastornos hemorrágicos deben sospecharse. El diagnóstico precoz y el tratamiento temprano disminuyen la morbimortalidad relacionada con este tipo de manifestaciones.


ABSTRACT Haematological alterations are common in patients with systemic lupus erythematosus (SLE). These haematological manifestations may be expressed related to the involvement of cells affected and coagulation changes. The compromise in coagulation is associated with thrombotic manifestations. Risk factors associated with thrombosis have been described, such as the presence of elevated levels of homocysteine, acquired deficit of protein S, protein C, and antithrombin. However, the haemorrhagic diathesis has also been described at a lower frequency and related to the acquired deficiency of coagulation factors caused by the development of autoantibodies directed against coagulation factors. The cases are presented of 3 patients with juvenile SLE with unusual haematological manifestations, as well as a review of the literature in relation to them. The haematological manifestations in juvenile SLE are not only related to alterations in cell lines, vascular thrombosis and bleeding disorders should also be suspected. Early diagnosis and treatment reduces morbidity and mortality related to this type of manifestations.

ABSTRACT

Introducción: los accidentes cerebrovasculares son raros en niños, y generalmente se asocian a trombofilias; sin embargo, se deben considerar procesos infecciosos de tipo miocarditis infecciosa que pudieran conducir a formación de trombos. Presentación del caso: se presenta el caso de un niño de 13 meses de edad, previamente sano, con evidencia de accidente cerebrovascular isquémico extenso, que comprometió ambos hemisferios cerebrales, con antecedente de infección gastrointestinal que podría sugerir sepsis y miocarditis secundaria a esta, que contribuye a un evento trombótico, el cual, probablemente, desencadenó el proceso cerebrovascular descrito. Conclusiones: las infecciones, aunque se han relacionado como la tercera causa de eventos cerebrovasculares, se deben tener en cuenta para así instaurar tratamiento antibiótico oportuno, y con esto, evitar secuelas(AU)


Introduction: cerebrovascular accidents are rare in children, and they are generally associated with thrombophilia. However, infectious processes such as myocarditis should also be considered, for they may lead to thrombus formation. Case presentation: a previously healthy 13-month-old male child presents with evidence of extensive ischemic cerebrovascular accident compromising both cerebral hemispheres, with a history of gastrointestinal infection which might suggest the presence of sepsis and myocarditis secondary to it contributing to a thrombotic event which probably triggered the cerebrovascular process herein described. Conclusions: although they have been ranked as the third cause of cerebrovascular events, infections should be taken into account so as to timely indicate the appropriate antibiotic treatment and avoid the occurrence of sequels(AU)
