ABSTRACT

Abstract Introduction: the relationship between lipid fractions and cardiovascular risk is clear. However, the operational characteristics of total cholesterol (TC) for the diagnosis of dyslipidemias due to elevated LDL cholesterol (LDLC), hypertriglyceridemia and low HDL cholesterol (HDLC) are not clear. Objective: to establish the sensitivity (Sen) specificity (Spe) and predictive values (PPV and NPV) of TC (>200 mg/dL) for diagnosing various types of dyslipidemias. Materials and methods: a study of diagnostic tests using all the lipid profiles processed at the Hospital Universitario San Ignacio in Bogotá (Colombia) from January 2006 to January 2017. Sensitivity, Spe, PPV and NPV were calculated for each dyslipidemia and for each LDLC goal. Results: in 25,754 profiles, the average age was 53.6±18 years. The prevalence of elevated LDLC (based on the goals of 160, 130, 100, 70 or 55 mg/dL) was: 19.9%, 44.5%, 72.7%, 92.1% and 96.8%, respectively; for hypertriglyceridemia (>150 mg/dL) it was 44.7%, and for low HDLC (< 40 mg/dL) it was 33.9%. The sensitivity of TC (>200 mg/dL) for elevated LDLC according to the same goals was: 100%, 95%, 70%, 56% and 53%, with a specificity of: 59%, 81%, 94%, 95% and 92%; PPV=37%, 80%, 97%, 99% and 99%; and NPV=100%, 95%, 54%, 15% and 5.8%. For hypertrygliceridemia: Sen=61%, Spe=61%, PPV=55% and NPV=66%. For low HDLC: Sen=36%, Spe=42%, PPV=26% and NPV=54%. Conclusions: given the operational characteristics of TC>200 mg/dL, it should not be used as an isolated tool for diagnosing dyslipidemia due to LDLC, HDLC or hypertriglyceridemia.

Resumen Introducción: es clara la relation entre las fracciones lipídicas y riesgo cardiovascular, sin embargo, no son claras las características operativas del colesterol total (CT) para el diagnóstico de dislipidemias por colesterol LDL (C-LDL) elevado, hipertrigliceridemia y colesterol HDL (C-HDL) bajo. Objetivo: establecer sensibilidad (S), especificidad (E), y valores predictivos (VPP y VPN) del CT (>200 mg/dL) para diagnóstico de diferentes tipos de dislipidemias. Material y métodos: estudio de pruebas diagnosticas a partir de la totalidad de perfiles lipídicos procesados en el Hospital Universitario San Ignacio de Bogotá (Colombia), desde enero de 2006 hasta enero de 2017. Se calcularon S, E, VPP y VPN para cada dislipidemia y para cada meta de C-LDL. Resultados: en 25 754 perfiles, la edad promedio fue 53.6±18 años. Las prevalencias de C-LDL elevado (según metas de 160, 130, 100, 70 o 55 mg/dL) fueron: 19.9%, 44.5%, 72.7%, 92.1% y 96.8% respectivamente; hipertrigliceridemia (>150 mg/dL) 44.7% y C-HDL bajo (< 40 mg/dL) 33.9%. Las sensibilidades del CT (>200 mg/dL) para C-LDL elevado según las mismas metas fueron: 100%, 95%, 70%, 56% y 53% y especificidades: 59%, 81%, 94%, 95% y 92%. VPP=37%, 80%, 97%, 99% y 99%, y VPN=100%, 95%, 54%, 15% y 5.8%. Para hipertrigliceridemia: S=61%, E=61%, VPP=55% y VPN=66%. Para C-HDL bajo: S=36%, E=42%, VPP=26% y VPN=54%. Conclusiones: dadas las características operativas del CT>200 mg/dL, éste no debe ser utilizado como herramienta aislada para el diagnóstico de dislipidemia por C-LDL, por C-HDL, ni para hipertrigliceridemia.

ABSTRACT

Resumen La miocarditis eosinofílica es una entidad poco difundida ya que su diagnóstico histopatológico se realiza en casos de mayor severidad, donde la biopsia endomiocárdica es mandatoria. No obstante, dado que esta entidad suele superponerse a muchas patologías: las infecciosas, las inmunológicas, o asociadas a la hipersensibilidad y esto se asocia con la reversibilidad, es importante tenerla presente como entidad nosológica en cuadros agudos de la disfunción ventricular izquierda. Puede o no estar asociada a la eosinofilia periférica, su ausencia no descarta la enfermedad. Se presenta un paciente joven (35 años de edad), con un cuadro clínico de la falla cardiaca aguda que progresa rápidamente a choque cardiogénico con poca respuesta al manejo inicial instaurado (inodilatadores, vasopresores), requiriendo el uso de soporte circulatorio extracorpóreo. Como antecedente: la reciente finalización del tratamiento para leishmaniasis mucocutánea, con antimoniato de meglumina (glucantime). Informe del servicio de patología: miocarditis eosinofílica. Se logra el destete del soporte circulatorio, presenta mejoría de la función sistólica del ventrículo izquierdo con recuperación total del cuadro clínico. Este caso es relevante en cuanto a diagnóstico de disfunción ventricular aguda, con una asociación previamente no descrita con antimoniato de meglumina (glucantime), nos recuerda la importancia de realizar: la biopsia endomiocárdica para definir la etiología, la toma de decisiones de terapias avanzadas, conociendo que en ciertas circunstancias puede presentarse reversibilidad de la disfunción miocárdica y mejoría del cuadro clínico.


Abstract Eosinophilic myocarditis is a little-known entity as its histopathological diagnosis is conducted in the most severe cases, where an endomyocardial biopsy is mandatory. However, because this condition is usually overlaps with many pathologies -infectious, immunological, or associated to hypersensitivity, and this is related to reversibility- it is important to keep it in mind as a nosological entity in acute presentations of left ventricular dysfunction. It may or may not be associated to peripheral eosinophilia, though its absence does not rule out the condition. A case of a young male patient (35 year-old) with clinical features of acute cardiac failure which progresses rapidly into cardiogenic shock with low response to initial management (inodilators, vasopressors) requiring the use of extracorporeal circulation support is presented. Previous history: recent completion of treatment for ucocutaneous leishmaniases with meglumine antimoniate (glucantime). Pathology service report: eosinophilic yocarditis. Weaning from circulatory support is achieved, presenting an improvement of systolic function of the left ventricle with complete recovery of the symptomatology. This case is relevant due to the diagnosis of acute ventricular dysfunction with an association with meglumine antimoniate (glucantime) that was previously not described. It reminds of the importance of carrying out an endomyocardial biopsy in order to define the aetiology and the decision-making on advances therapies, knowing that in some circumstances there can be a reversibility of the myocardial function and an improvement of the symptomatology.
