RESUMEN
Presentamos el caso de un paciente varón de 24 años con hemofilia A de 14 años de evolución. El paciente presentó hemartrosis recurrente en rodilla derecha, luego desarrolló artritis séptica en dicha articulación producida por Serratia marcescens con respuesta satisfactoria al lavado intra-articular con solución salina y 28 días de tratamiento con carbapenémicos. En pacientes con artritis séptica, hemartrosis previa y múltiples ingresos hospitalarios debe sospecharse la presencia de este germen. El tratamiento es quirúrgico y con antibióticos de amplio espectro.
We present the case of a 24-year-old male patient with hemophilia A of 14 years of evolution. The patient presented recurrent hemarthrosis in the right knee, who developed septic arthritis in knee due to Serratia marcescens with a satisfactory response to intra-articular lavage with saline solution and 28 days of treatment whith carbapenems. In patients with septic arthritis, previous hemarthrosis and multiple hospital admissions, the presence of this germ should be suspected. The treatment is surgical and with broad spectrum antibiotics.
RESUMEN
Background: The numbers of severe COVID cases and COVID-related deaths on the African continent are lower than expected. We hypothesize that this paradox may be due to the achieved immunity in black Africans. Materials and Methods: A prospective study was conducted on Angolan people who performed the Panbio Abbott COVID-19 IgG/IgM Rapid Test in a health unit in Luanda. One hundred randomly selected subjects in those with positive immunoglobulin G (IgG) underwent the serological mini VIDAS BIOMERIEUX test. Results: In our population study (2409 subjects), 791 (32.83%) had positive IgG at the Panbio Abbott COVID-19 test. One hundred were randomly selected. The mean age was 39.55, and 96% were males. The positivity to IgG was validated in 72 subjects at the mini VIDAS BIOMERIEUX test. Conclusion: These results support our hypothesis that in the Angolan/African population a previously achieved immunity may be one of the reasons why this continent was not affected by COVID-19 as expected.
