ABSTRACT
OBJECTIVES: Herpes zoster is characterized by acute neuritis and post-herpetic neuralgia. Currently, data concerning the zoster-associated impact on quality of life and healthcare resource utilization in Brazil are scarce. This study measured the zoster-associated burden in a Brazilian population. METHODS: This was a prospective, observational, single-cohort study conducted in a primary hospital's emergency room in São Paulo, Brazil. Patients enrolled at various timepoints during a zoster episode were followed over 180 days. The Zoster Brief Pain Inventory and the Initial Zoster Impact Questionnaire assessed zoster-associated pain. The EuroQoL assessed the impact of herpes zoster and/or zoster-associated pain on quality of life. Healthcare resource utilization was assessed by patient-reported questionnaires. RESULTS: One-hundred forty-six zoster patients were enrolled [mean (SD) age of 69.9 (10.9) years]. Mean (SD) worst pain scores decreased from 5.3 (3.5) at baseline to 1.9 (3.0) 180 days following rash onset. Mean (SD) EuroQoL scores significantly decreased from 0.9 (0.2) before rash appearance to 0.7 (0.2) after rash onset (p<0.001), followed by gradual improvements in quality of life over 180 days, with pre-herpes zoster quality of life achieved at the end of the observation period. The majority of patients purchased prescription medications (89.7%) and required doctor's office visits (65.8%) for zoster episodes. CONCLUSIONS: Herpes zoster is associated with a significant disease burden, including zoster-associated pain, impaired quality of life and increased healthcare resource utilization in Brazil. These results support the implementation of early intervention and prevention programs such as vaccinations to reduce the herpes zoster-associated disease burden in Brazil.

AbstractBackground: Herpes zoster is a distressing illness that significantly reduces patients' quality of life. However, Costa Rican data regarding the clinical burden of herpes zoster and associated health care resource utilization is limited. This study aimed to assess the zoster-associated burden evaluating pain, impact on quality of life and health care resource utilization in a Costa Rican sample.Methods:Herpes zoster patients recruited in Costa Rica at a private geriatric practice were enrolled at various time points during a zoster episode and were actively followed over 6 months. Outcomes including zoster-associated pain, quality of life and health care resource utilization were assessed via patient self-reported questionnaires.Results: 50 zoster patients were included [68.0% female, mean (SD) age = 69.5 (10.8) years]. Zoster-associated pain decreased over time while quality of life improved though without full base recovery. The highest health care resource utilization included doctor's office (98.0%), emergency room (60.0%) and specialists (60.0%) visits. Sixteen (32.0%) patients were hospitalized [mean (SD)= 4.3 (4.1) days].Conclusion: Similar to other Latin American countries, high herpes zoster burden was observed in a private geriatric practice in Costa Rica, supporting the need for early intervention and preventive strategies, one of such could be the implementation of a HZ vaccination program.
ResumenJustificación: El herpes zoster es una enfermedad estresante que reduce significativamente la calidad de vida de los pacientes. Sin embargo, datos relativos a la carga clínica de herpes zoster y la utilización de recursos de salud son limitados en Costa Rica. El objetivo de este estudio fue evaluar la carga asociada al herpes zoster evaluando dolor, impacto sobre la calidad de vida y utilización de recursos de salud en una muestra costarricense.Métodos:Pacientes con herpes zoster fueron reclutados en una práctica geriátrica privada en diferentes etapas de un episodio de zoster y fueron activamente seguidos durante 6 meses. Se evaluaron los resultados en el paciente, incluyendo el dolor asociado a zoster, calidad de vida y utilización de recursos de salud mediante cuestionarios autoadministrados.Resultados: Se incluyeron 50 pacientes con herpes zoster [68,0% mujeres, media de edad (SD) = 69.5 (10.8) años]. El dolor asociado a zoster disminuyó con el tiempo mientras que calidad de vida mejoró, aunque sin plena recuperación comparado con la calidad de vida inicial. La utilización de recursos de salud más alta fue visitas al consultorio (98.0%), visitas a sala de urgencias (60.0%) y visitas a especialistas (60.0%). Dieciséis pacientes (32.0%) fueron hospitalizados [media (SD) = 4.3 (4.1) días].Conclusión: Similar a otros países de América Latina, se observó una alta carga de enfermedad debido a herpes zoster en una práctica privada geriátrica en Costa Rica, lo cual respalda la necesidad de la intervención temprana y uso de estrategias preventivas, una de las cuales podría ser la implementación de un programa de vacunación a herpes zoster.

El herpes zoster (HZ) es causado por reactivación del virus varicela-zoster latente. Se caracteriza por exantema vesicular unilateral, neuri-tis aguda y neuralgia posherpética. Aún hay escasos datos sobre el do-lor asociado al HZ (DAZ), su repercusión en la calidad de vida (CdV) y la utilización de recursos sanitarios (URS) asociada en Argentina. En este estudio prospectivo, observacio-nal, de una cohorte, realizado en 3 centros argenti-nos se valuó la carga de morbilidad asociada al HZ en Argentina en contextos clínicos reales. Los pa-cientes fueron enrolados en diversos momentos du-rante un episodio herpético, y seguidos activamen-te los días 14, 21, 30, 60, 90, 120, 150 y 180. Hubo 96 enrolados(edad 70±10,7 años; tiempo desde el inicio del exantema 16±16,9 días[media±DE]). El puntaje del peor dolor (media±DE) disminuyó de 5,5±3,1 en el enrolamiento a 0,2±0,7 a los 180 días de seguimiento. El puntaje del cuestionario de cali-dad de vida EQ-5D (media±DE) disminuyó significa-tivamente de 0,8±0,1 antes del inicio del exantema a 0,6±0,2 tras su inicio (P<0,001), con mejoría gra-dual de la CdV durante 180 días (0,9±0,1), hasta un puntaje similar al previo al inicio del exantema. La URS más frecuente fueron visitas al consultorio mé-dico (96,9%). La gran mayoría de pacientes compró medicamentos recetados (95,8%) y de venta sin receta (83,3%) para los episodios herpéticos. El DAZ estuvo asociado a gran carga de morbili-dad, deterioro de CdV, aumento de URS y costos asociados en Argenti-na. Esto subraya la importancia de estrategias de intervención precoz o prevención para disminuir la carga de morbilidad asociada al HZ
Herpes zoster (HZ) is caused by re-activation of latent varicella zoster virus and is characterized by unilateral, vesicular cutaneous eruptions, acute neuritis, and post-herpetic neuralgia. To date, data on HZ associated pain (ZAP) and its impact on quality of life (QoL) and associated healthcare resource utilization use (HCRU) in Argentina is scarce. This study assessed the burden of illness associated with HZ in Argentina in a real-life clinical setting. This was a prospective, observational, single-cohort study conducted in 3 sites across Argentina. Patients were enrolled at various time points during the course of a zoster episode and were actively followed on days 14, 21, 30, 60, 90, 120, 150, and 180. There were 96 HZ patients enrolled with a mean±SD age and time since rash onset of 70±10. 7 years and 16±16. 9 days, respectively. Mean±SD worst pain score decreased from 5. 5±3. 1 at enrollment to 0. 2±0.7 at 180 days of follow-up. The mean±SD EQ-5D score significantly decreased from 0. 8±0. 1 before rash onset to 0. 6±0. 2 after rash onset (P <0.001) followed by gradual improvement in QoL over 180 days (0. 9±0.) reaching a similar score to that prior to rash onset. The most common HCRU was visits to the doctor's office with 96.9%. The vast majority of patients purchased prescription medications (95.8%) and over-the-counter medications (83.3%) for HZ episodes. ZAP was found to be associated with severe burden of illness, impaired QoL, increased HCRU, and associated cost in Argentina; highlighting the importance of early intervention or prevention strategies to reduce HZ-associated disease burden
