RESUMEN
Resumen La enfermedad COVID-19, causada por el virus SARS-CoV-2, surgió a fines de 2019 en Wuhan, China. La evolución clínica es variable, así como la tasa de mortalidad, que es mayor en pacientes mayores de 65 años y en quienes padecen enfermedades subyacentes. Las inmunodeficiencias son potenciales factores de riesgo para formas graves de COVID-19. Los pacientes con inmunodeficiencias tienen además mayor frecuencia de complicaciones no infecciosas, que podrían representar un riesgo adicional. Hasta el momento existen escasas publicaciones sobre asociación COVID-19 e inmunodeficiencias humorales. Considerando la importancia del estudio de esta nueva enfermedad viral y de su potencial repercusión en la salud de los pacien tes con inmunodeficiencias presentamos seis casos de COVID-19 en adultos con déficit de anticuerpos (tres mujeres y tres varones, edad promedio 48.5 años, rango 20-67). Cuatro tenían inmunodeficiencias primarias inmunodeficiencia común variable (n 3) y agammaglobulinemia ligada al cromosoma X (n 1). Los otro dos tenían hipogammaglobulinemia secundaria, en un caso asociada a timoma (síndrome de Good), y en el otro a tratamiento con rituximab. La evolución fue favorable en todos menos en el paciente con síndrome de Good, quien presentaba un marcado deterioro del estado general antes de contraer COVID-19.
ABSTRACT
Abstract COVID-19, caused by SARS-CoV-2, emerged in late 2019 in Wuhan, China. Its clinical course is variable, as well as the mortality rate, which is higher among people over 65 years of age and persons with underlying conditions. Immunodeficiencies are po tential risk factors for severe forms of COVID-19. Furthermore, patients with immunodeficiencies often undergo non-infectious complications, which could bear additional risk. So far, few reports of patients with COVID-19 and humoral immunodeficiencies have been published. Considering the importance of the study of this new viral disease and its potential health impact on patients with immunodeficiency disorders, we present six cases of COVID-19 in patients with impaired humoral immunity. Three were women and three were men. The average age was 48.5 years (range 20-67). Four had been diagnosed with primary antibody deficiency three had common variable immunodeficiency and one had X-linked agammaglobulinemia. The other two patients had secondary hypogammaglobulinemia, one was associated with thymoma (Good's syndrome), and the other was associated with rituximab treatment. The evolution was favorable in all except the patient with Good's syndrome, who pre sented a marked decline in clinical status before contracting COVID-19.
