RESUMO
Introduction Vaccination is one of the pillars for the prevention of COVID-19 in healthcare workers (HCWs). The present study aims to determine the effectiveness of vaccination for COVID-19 as well as hybrid immunity in previously infected HCWs in a hospital in a developing country. Methods An observational study was carried out on health personnel with a complete COVID-19 vaccination schedule according to their previous infection status, with a follow-up period of 15 months. Results In this study, 335 subjects were enrolled, of which 32.8% had a previous infection with COVID-19. The safety of vaccines was determined by estimating the presence of adverse effects of vaccination and immunization (AEVI), with the first and second doses showing an incidence of 8.2% and 9.5% respectively, during the second and third waves. Around 5.7% of immunized personnel were sick and 8.4% in the fourth wave; the serum value of neutralizing antibodies was normal at 60.2% with no differences between vaccines (p=0.164). However, in personnel with hybrid immunity, there were normal levels of antibodies in 81.8% of cases (p= 0.023), fewer days of medical leave (6.4 days (standard deviation=1.4) (p=0.067)), higher immunoglobin values ââ(p=0.011) and an insignificantly (p=0.248) lower rate of COVID-19 presentation. Conclusion Vaccination, when applied to people who previously acquired natural immunity, generates a hybrid immunity that is robust, and could have a longer duration, as well as greater efficacy for new COVID-19 variants of concern.
RESUMO
Wiskott-Aldrich syndrome was first reported clinically in 1937, and in 1954 the classic triad was identified: eccema, recurrent infections and thrombocytopenia with an X-linked transmission. Its incidence is estimated at 1 to 10 in one million live births per year. Wiskott Aldrich syndrome is caused by mutations in a gene in the short arm of chromosome X that encodes the Wiskott-Aldrich syndrome protein (WASp), which identification and sequencing was first performed in 1994, and since then about 300 mutations have been reported. This paper describes the case of a boy with Wiskott-Aldrich syndrome, with clinical and genetic diagnosis, with a considerable diagnostic delay attributable to an atypical presentation misdiagnosed as immune thrombocytopenia.
El síndrome de Wiskott Aldrich fue descrito en 1937 y en 1954 se identificó su tríada característica: eccema, infecciones recurrentes y trombocitopenia, con herencia ligada al cromosoma X. Su incidencia se calcula en 1 a 10 por cada millón de recién nacidos vivos por año. Su causa es la mutación del gen localizado en el brazo corto del cromosoma X, que codifica la proteína del síndrome Wiskott-Aldrich (WASp), cuya identificación y secuenciación se realizan desde 1994, lo que ha permitido describir al menos 300 defectos genéticos. Comunicamos un caso de síndrome de Wiskott-Aldrich con diagnóstico clínico y genético, tipo nonsense Q203X, en el exón 7, en un preescolar con ausencia de eccema.
RESUMO
Latex allergy is an underdiagnosed condition, and it is the second cause of perioperative anaphylaxis. This condition represents a clinical challenge due to the severity of reactions caused by the exposure to latex in allergic individuals. It is necessary to know the risk factors in order to suspect the diagnosis of latex allergy, and to apply the preventive measures in the medical care of patients allergic to latex. Other safety measures and pre-medication, as avoiding objects and medical equipment made of latex, should be taken since they can cause anaphylaxis. We present six cases of patients with latex allergy, who underwent surgical procedures. In five of them with positive skin test with latex, we used preventive measures and pre-medication 72 hours before and 48 hours after surgery. Only one patient, a sixty year old woman, with urticaria related to kiwi, avocado and potatoes, who was surgically intervened without pre-medication, presented grade IV anaphylaxis.
