Prevalencia de diagnóstico tardío en infección por VIH / Prevalence of late diagnosis of HIV infection

OBJETIVO: Prevalencia de diagnóstico tardío (DT) e identificar oportunidades perdidas. MÉTODOS: Estudio observacional retrospectivo de nuevos diagnósticos de VIH entre el 2013 y el 2018 en nuestra área de referencia. Se analizan variables sociodemográficas y clínico-analíticas en el momento del diagnóstico. Se revisa la atención sanitaria prestada en los 5 años previos para identificar oportunidades perdidas de diagnóstico precoz. RESULTADOS: Setenta y cuatro pacientes. Edad media 35,3 años, 83,8% hombres. Prevalencia de DT del 44,6% y de enfermedad avanzada del 23,0%. Tendencia aumentada de DT en los pacientes mayores de 40 años, en especial entre los españoles. Ser testado de VIH protege de presentar un DT. Todos los pacientes con contacto previo con el sistema sanitario presentaban indicadores o factores de riesgo asociados al VIH, pero tan solo el 50% había sido testado del VIH. CONCLUSIONES: A pesar del contacto repetido de nuestros pacientes con el sistema sanitario, casi la mitad de nuevos diagnósticos se realizan de forma tardía. Es importante implementar estrategias que permitan identificar mejor a aquellos pacientes con factores de riesgo o indicadores clínicos para una detección más precoz del VIH

BACKGROUND: Prevalence of late diagnosis (LD) and identifying missed opportunities. METHODS: Retrospective observational study of new HIV diagnoses between 2013 and 2018 in our referral area. Sociodemographic and clinical-analytical variables were analysed at the time of diagnosis. The patient's clinical history in the last 5 years before the HIV diagnoses was reviewed to identify missed opportunities for early diagnosis. RESULTS: Seventy-four patients were included. The prevalence of LD was 44.6%, and 23% as an advanced disease. A tendency for LD was observed in patients older than 40 years, especially among Spaniards. Being tested 11for HIV protected against LD. All patients who had previous contact with the health system had clinical indicators or risk factors associated with HIV, but only 50% had ever been tested in their lifetime of HIV. CONCLUSIONS: In spite of multiple contacts with our health system, almost half of the new cases of HIV infection are diagnosticated late. Different strategies should be implemented to improve the identification of the risk factors and clinical indicators of possible HIV infection

[Prosthetic joint infection: a prospective study in five Catalonian hospitals]. / Infección de prótesis articulares: estudio prospectivo en 5 hospitales de Cataluña.

BACKGROUND: Prosthetic joint infections are a cause of increasing morbidity and medical expenditure. OBJECTIVES: To determine the incidence and the clinical and the epidemiological characteristics of knee and hip prosthetic infections (PI) in patients undergoing elective surgery in five Catalonian hospitals. To determine the predictive factors of PI. METHODS: A total of 425 patients operated on between 8 January and 8 July 2001 were prospectively followed for a period of two years. The cumulative incidence, incidence rate and effect measures were determined. Logistic regression was used to identify variables associated with PI. RESULTS: Average age was 71 years and 63.1% were women. Antibiotic prophylaxis with cefazolin was given to 44.7% of the patients, with a mean duration of two days. Prophylaxis was administered during anesthesia induction in 75.6% of the patients. Among the total, 63.4% of the patients were ASA 2. Microbiological confirmation was obtained in all the infected patients; Staphylococcus epidermidis was found in 58%. Fourteen PI were diagnosed, 71% during the first 3 months, with a cumulative incidence of 3.29% and a 3-month incidence rate of 63 patients/10,000 patients/month. Diabetes mellitus was the only variable related to PI in the multivariate analysis: 3.18, 95% CI (1.1-9.9). CONCLUSIONS: The cumulative incidence of PI was slightly higher than that seen in other studies. Variations were observed in the antibiotic used for prophylaxis, and the place where it was administered. PI occurred 3.18 times more frequently in diabetic patients.

Infección de prótesis articulares: estudio prospectivo en 5 hospitales de Cataluña / Prosthetic joint infection: A prospective study in five Catalonian hospitals

Antecedentes. Las infecciones de prótesis (IP) articulares son causa de morbilidad y aumento del gasto. Objetivos. Conocer la incidencia y características clínicas y epidemiológicas de las IP de cadera y rodilla, en pacientes intervenidos en cinco hospitales. Identificar factores predictores. Métodos. Se identificaron prospectivamente 425 pacientes intervenidos entre el 8 de enero y el 8 de julio de 2001. Se realizó un seguimiento de 2 años. Se determinaron la incidencia acumulada (IA), tasa de incidencia (TI) y medidas de efecto. Para identificar variables relacionadas con la IP se realizó una regresión logística. Resultados. La edad media fue de 71 años; el 63,1% fueron mujeres. En el 44,7% se realizó profilaxis antibiótica con cefazolina, con una duración media de 2 días. Se administró durante la inducción anestésica en el 75,6%. El 63,4% de los pacientes tenían un ASA 2. Se obtuvo confirmación microbiológica en todos, aislándose Staphylococcus epidermidis en el 58%. Se diagnosticaron 14 IP, 71% de ellas en el primer trimestre; con una IA acumulada a los 2 años del 3,29%, una tasa de incidencia a los 3 meses de 63 casos por 10.000 sujetos/mes de exposición. En el análisis multivariado la diabetes mellitus fue la única variable relacionada con la IP (OR: 3,18; IC 95%: 1,1-9,9). Conclusiones. La IA de la IP es algo superior que en otros estudios. Se evidencia una variabilidad en el antibiótico utilizado en la profilaxis y en el lugar de administración. La IP es 3,18 veces más frecuente en pacientes diabéticos (AU)
