An elevated HScore is associated with poor clinical outcomes in COVID-19 / Un HScore elevado se asocia a mal pronóstico en pacientes con COVID-19

BACKGROUND: Patients with Coronavirus Disease 2019 (COVID-19) frequently experience a hyperinflammatory syndrome leading to unfavorable outcomes. This condition resembles Secondary Hemophagocytic Lymphohistiocytosis (sHLH) described in neoplastic, rheumatic and other infectious diseases. A scoring system (HScore) that evaluates underlying immunosuppression, temperature, organomegaly, cytopenias, ferritin, triglycerides, fibrinogen and AST was validated for sHLH, and recently proposed to evaluate hyperinflammation in COVID-19. AIM: To assess the presence of sHLH among patients with COVID-19 admitted for hospitalization and to evaluate Hscore as a prognostic tool for poor outcomes. MATERIAL AND METHODS: One hundred forty-three patients aged 21-100 years (64% males) admitted because of COVID-19 were enrolled in a prospective study. HScore was calculated within 72 hours admission. The incidence of sHLH during hospitalization was evaluated. Additionally, the relationship between a HScore ≥ 130 points and either the requirement of mechanical ventilation or 60-days mortality was explored. RESULTS: The median HScore was 96 (33-169). A SHLH was diagnosed in one patient (incidence 0.7%), whose HScore was 169. After adjusting for age, sex, comorbidities and obesity, HScore ≥ 130 was independently associated with the composite clinical outcome (Hazard rartio 2.13, p = 0.022). CONCLUSIONS: sHLH is not frequent among COVID-19 patients. HScore can be useful to predict the risk for poor outcomes.

ANTECEDENTES: Los pacientes con Enfermedad por Coronavirus 2019 (COVID-19), experimentan frecuentemente un síndrome hiperinflamatorio que lleva a resultados desfavorables. Esta situación se asemeja al Síndrome Hemofagocítico Secundario (sHLH) descrito en enfermedades neoplásicas, reumatológicas y por otros agentes infecciosos. Un sistema simple de puntaje (HScore) que evalúa inmunosupresión, temperatura organomegalia, citopenias, ferritina, triglicéridos, fibrinógeno y AST ha sido validado para el diagnóstico de sHLH y ha sido propuesto recientemente para evaluar la hiperinflamación en COVID-19. OBJETIVO: Medir la frecuencia de sHLH entre pacientes con COVID-19 hospitalizados, y evaluar a HScore como una herramienta pronóstica. MATERIAL Y MÉTODOS: Ciento cuarenta y tres pacientes de 21 a 100 años (64% hombres) fueron ingresados en este estudio de cohorte prospectivo, unicéntrico. Se calculó HScore dentro de las primeras 72 horas desde el ingreso, y se midió la incidencia de sHLH durante la hospitalización. Adicionalmente, se evaluó la relación entre HScore ≥ 130 puntos y un desenlace compuesto de ventilación mecánica o muerte a los 60 días. RESULTADOS: La mediana de HScore fue 96 (33-169) puntos. Un paciente fue diagnosticado con sHLH (incidencia 0,7%). Luego de ajustar por edad, sexo, comorbilidades y obesidad, un HScore ≥ 130 se asoció de manera independiente con el desenlace compuesto. CONCLUSIONES: El sHLH no es frecuente en los pacientes con COVID-19. El uso de HScore puede ser útil para predecir el riesgo de desenlaces clínicos desfavorables.

Hepatitis sifilítica: reporte de una serie de casos / Syphilitic hepatitis: report of three cases

Liver involvement occurs in 0.2 to 3% of patients with syphilis. We report three patients with liver involvement in syphilis. A 52-year-old male presenting with erythema and malaise. Laboratory showed a gamma glutamyl transpeptidase (GGT) of 853 u/l, alkaline phosphatases of 1,010 U/L and VDRL was positive. Treatment with penicillin resolved the skin problem and normalized liver enzymes. A HIV positive 30-year-old male in peritoneal dialysis presenting with itching, malaise and markedly elevated GGT and alkaline phosphatases. VDRL was positive. He was treated with penicillin with remission of symptoms and enzyme normalization. A 43-year-old male presenting with erythema, malaise, arthralgias and elevated GGT and alkaline phosphatases. VDRL was positive and treatment with penicillin reverted symptoms and laboratory abnormalities.
