Objective. Controversial results on remdesivir efficacy have been reported. We aimed to report our real-life experience with the use of remdesivir from its availability in Spain. Methods. We performed a descriptive study of all patients admitted for ≥48 hours with confirmed COVID-19 who received remdesivir between the 1st of July and the 30th of September 2020. Results. A total of 123 patients out of 242 admitted with COVID-19 at our hospital (50.8%) received remdesivir. Median age was 58 years, 61% were males and 56.9 % received at least one anti-inflammatory treatment. No adverse events requiring remdesivir discontinuation were reported. The need of intensive care unit admission, mechanical ventilation and 30-days mortality were 19.5%, 7.3% and 4.1%, respectively. Conclusion. In our real-life experience, the use of remdesivir in hospitalized patients with COVID-19 was associated with a low mortality rate and good safety profile.

Cada vez sabemos más sobre este enemigo mortal de la familia de los Betacoronavirus, llamado inicialmente 19-nCoV, causante de la COVID-19 (Coronavirus infectous disease por su sigla en inglés), hoy clasificado SARS-CoV-2, porque es responsable de producir el SARS (síndrome respiratorio agudo severo, por sus siglas en inglés) y que comparte una fuerte homología de secuencia con el SARS-CoV, su primo hermano causante de la epidemia en 2003 del SARS, ambos capaces de diseminarse rápidamente, en particular este, y causar un gran caos mundial como ha sucedido con esta pandemia. Con base en estudios previos de focalización en el SARS-CoV, y también en el virus causante del MERS (síndrome respiratorio del Oriente Medio, por sus siglas en inglés), y con el conocimiento que se tiene actualmente sobre el SARS-CoV-2, se exploran en este articulo algunas opciones terapéuticas para el manejo de la infección por este virus complejo y con capacidad letal, mencionando algunos aspectos de relevancia patogénica.Se enfatizó en las posibles alternativas de manejo desde la fisiopatología y patogénesis hasta la evidencia actualmente disponible. Exploraremos el uso probable de ECA2 recombinante, algunas moléculas experimentales, revisaremos los antimaláricos (cloroquina e hidroxicloroquina), esteroides, azitromicina, antivirales específicos como remdesivir, lopinavir/ritonavir, biológicos como tocilizumab, anticuerpos monoclonales antivirales, y haremos énfasis en la trasfusión de plasma de convalecientes desde el principio de inmuni- zación pasiva, de gran utilidad

The development of direct-acting antivirals (DAAs) has been a turning point in chronic hepatitis C treatment. With an efficacy rate on viral eradication close to 100% and an excellent safety profile, they have replaced interferon-based treatments as first-line therapy for hepatitis C virus (HCV). Following the encouraging results observed during the first years with these treatments, new publications suggested an unexpectedly high incidence of hepatocellular carcinoma (HCC) in patients previously treated with DAAs as well as a higher HCC recurrence rate in them. The possible interaction between DAAs and HCC and its impact on HCC incidence and recurrence still remains controversial. The aim of the present work is to review the current state of the matter by analyzing studies that evaluate the association between chronic hepatitis C treatment with DAAs and the development of HCC either de novo or as a recurrence. Following this, clinical practice recommendations are done.

The impact of drug–drug interactions (DDI) between ritonavir-boosted lopinavir (LPV-r) to treat patients with coronavirus disease 2019 (COVID-19) and commonly used drugs in clinical practice is not well-known. Thus, we evaluated the rate and severity of DDI between LPV-r for COVID-19 treatment and concomitant medications. This was a cross-sectional study including all individuals diagnosed of SARS-CoV-2 infection treated with LPV-r and attended at a single center in Southern Spain (March 1st to April 30th, 2020). The frequency [95% confidence interval (95% CI)] of potential and major DDI were calculated. Overall, 469 patients were diagnosed of COVID-19, 125 (27%) of them were prescribed LPV-r. LPV-r had potential DDI with concomitant medications in 97 (78%, 95% CI 69–85%) patients, and in 33 (26%, 95% CI 19–35%) individuals showed major DDI. Twelve (36%) patients with major DDI and 14 (15%) individuals without major DDI died (p = 0.010). After adjustment, only the Charlson index was independently associated with death [adjusted OR (95% CI) for Charlson index ≥ 5: 85 (10–731), p, This study has not been funded.

Resumen Objetivo: identificar y caracterizar las acciones/intervenciones realizadas desde los servicios farmacéuticos en el abordaje de pacientes con hepatitis C y proponer una vía clínica para la gestión de la enfermedad que incluya la participación del farmacéutico. Método: revisión sistemática en PubMed y EMBASE empleando los términos “Hepatitis C”, “Pharmaceutical Services”, “Community Pharmacy Services”, y “Pharmacies”; artículos publicados hasta el 31 de marzo de 2019, cuyo tema central fueran las actividades realizadas por los servicios farmacéuticos en la atención a pacientes con hepatitis C. Se recopiló información sobre la actividad realizada, responsable, si la intervención era individual o colectiva y el entorno de aplicación. Las actividades se agruparon en promoción y prevención, gestión administrativa, atención farmacéutica, investigación y otros servicios de apoyo. De acuerdo con esto, se propuso una vía clínica para el manejo de la hepatitis C con participación del farmacéutico. Resultados: se incluyeron 60 artículos, principalmente de estudios descriptivos. La mayoría de las publicaciones reportó intervenciones realizadas en Estados Unidos y España. Se identificó la participación del personal farmacéutico en cada una de las etapas del proceso de atención, que incluye la provisión de servicios de reducción del daño, tamizaje del virus de la hepatitis C, vinculación de los pacientes al tratamiento, prescripción de medicamentos y órdenes de laboratorio. Conclusiones: se identifican y caracterizan las acciones/intervenciones realizadas desde el servicio farmacéutico para el manejo de la hepatitis C y se propone una vía clínica en la que se integran los servicios profesionales farmacéuticos a las demás actividades de la atención del paciente. Abstract Objective: To identify and characterize the actions/interventions carried out by pharmaceutical services to approach patients with Hepatitis C and propose a clinical pathway for managing the disease that involves pharmacists. Methodology: A systematic review was conducted in PubMed and EMBASE using the terms “Hepatitis C,” “Pharmaceutical Services,” “Community Pharmacy Services,” and “Pharmacies.” Articles published until March 31, 2019, whose central topic was the activities carried out by the pharmaceutical services in the care of patients with Hepatitis C, were included. Information on the activity performed, the person in charge, whether the intervention was individual or collective, and the implementation environment was collected. The activities were grouped into promotion and prevention, administrative management, pharmaceutical care, research, and other support services. Based on the above, a clinical pathway for the management of Hepatitis C involving pharmacists was proposed. Results: Sixty articles were included, mainly descriptive studies. Most publications reported interventions in the United States and Spain. Pharmaceutical staff involvement was identified at each stage of the care process, including the provision of harm reduction services, Hepatitis C virus screening, enrolling patients to treatment, medication prescription, and laboratory orders. Conclusions: The actions/interventions carried out by the pharmaceutical service for Hepatitis C management were identified and characterized. A clinical pathway has been proposed to integrate professional pharmaceutical services with other patient care activities.

Our objective was to compare clinical protocols for the treatment of the novel coronavirus disease 2019 (COVID-19) among different hospitals in Andalusia, Spain. We reviewed the current COVID-19 protocols of the 15 largest hospitals in Andalusia. Antiviral treatment, empirical antibacterial agents, adjunctive therapies, anticoagulant treatment, supportive care, hospital organization, and discharge recommendations were analyzed. All protocols included were the latest updates as of July 2020. Hydroxychloroquine in monotherapy was the most frequent antiviral drug recommended for mild respiratory illness with clinical risk factors (33.3%). Combined hydroxychloroquine with azithromycin or lopinavir/ritonavir was found in 40% of protocols. The recommended treatment for patients with mild and moderate pneumonias was different antiviral combinations including hydroxychloroquine plus azithromycin (93.3%) or hydroxychloroquine plus lopinavir/ritonavir (79.9%). Different combinations of hydroxychloroquine and lopinavir/ritonavir (46.7%) and triple therapy with hydroxychloroquine, azithromycin, and lopinavir/ritonavir (40%) were the most recommended treatments for patients with severe pneumonia. There were five corticosteroid regimens, which used dexamethasone, methylprednisolone, or prednisone, with different doses and treatment durations. Anakinra was included in seven protocols with six different regimens. All protocols included prophylactic heparin and therapeutic doses for thromboembolism. Higher prophylactic doses of heparin for high-risk patients and therapeutic doses for patients in critical condition were included in 53.3% and 33.3% of protocols, respectively. This study showed that COVID-19 protocols varied widely in several aspects (antiviral treatment, corticosteroids, anakinra, and anticoagulation for high risk of thrombosis or critical situation). Rigorous randomized clinical trials on the proposed treatments are needed to provide consistent evidence.

From January 2020, COVID-19 is spreading around the world producing serious respiratory symptoms in infected patients that in some cases can be complicated by the severe acute respiratory syndrome, sepsis and septic shock, multiorgan failure, including acute kidney injury and cardiac injury. Cost and time efficient approaches to reduce the burthen of the disease are needed. To find potential COVID-19 treatments among the whole arsenal of existing drugs, we combined system biology and artificial intelligence-based approaches. The drug combination of pirfenidone and melatonin has been identified as a candidate treatment that may contribute to reduce the virus infection. Starting from different drug targets the effect of the drugs converges on human proteins with a known role in SARS-CoV-2 infection cycle. Simultaneously, GUILDify v2.0 web server has been used as an alternative method to corroborate the effect of pirfenidone and melatonin against the infection of SARS-CoV-2. We have also predicted a potential therapeutic effect of the drug combination over the respiratory associated pathology, thus tackling at the same time two important issues in COVID-19. These evidences, together with the fact that from a medical point of view both drugs are considered safe and can be combined with the current standard of care treatments for COVID-19 makes this combination very attractive for treating patients at stage II, non-severe symptomatic patients with the presence of virus and those patients who are at risk of developing severe pulmonary complications.

ObjectivesSARS-CoV-2 is a rapidly evolving pandemic causing great morbimortality. Medical therapy with hydroxicloroquine, azitromycin and protease inhibitors is being empirically used, with reported data of QTc interval prolongation. Our aim is to assess QT interval behaviour in a not critically ill and not monitored cohort of patients.DesignWe evaluated admitted and ambulatory patients with COVID-19 patients with 12 lead electrocardiogram at 48 hours after treatment initiation. Other clinical and analytical variables were collected. Statistical analysis was performed to assess the magnitude of the QT interval prolongation under treatment and to identify clinical, analytical and electrocardiographic risk markers of QT prolongation independent predictors.ResultsWe included 219 patients (mean age of 63.6 ± 17.4 years, 48.9% were women and 16.4% were outpatients. The median baseline QTc was 416 ms (IQR 404–433), and after treatment QTc was prolonged to 423 ms (405–438) (P < 0.001), with an average increase of 1.8%. Most of the patients presented a normal QTc under treatment, with only 31 cases (14,1 %) showing a QTc interval > 460 ms, and just one case with QTc > 500 ms. Advanced age, longer QTc basal at the basal ECG and lower potassium levels were independent predictors of QTc interval prolongation.ConclusionsAmbulatory and not critically ill patients with COVID-19 treated with hydroxychloroquine, azithromycin and/or antiretrovirals develop a significant, but not relevant, QT interval prolongation.What is already known about this subject?Treatment for COVID 19 with empirical drugs hydroxicloroquine, azitromycin and protease inhibitors affects ventricular repolarization by prolonging the QT interval in a variable degree basing upon heterogeneous studiesWhat does this study add?Not critically ill patients with COVID 19 develop a non relevant QT interval prolongation, leading to a modest arrhythmic risk increase, overall in patients with normal basal ECGHow might this impact on clinical practice?Our findings are significant as ECG monitoring of COVID 19 patients is costly and difficult. Ambulatory and stable patients with normal basal ECG might nor benefit from QT assessment afeter treatment initiation

Introducción: debido a la emergencia del coronavirus SARS-CoV-2 desde diciembre del 2019, se ha generado un gran volumen de producción científica, en algún caso incierta o controvertida especialmente en el manejo farmacológico de los pacientes con esta infección; por lo tanto, se considera relevante buscar alternativas metodológicas para realizar su síntesis rigurosa, sistemática y de calidad, pero con menor tiempo de ejecución y menor costo. Objetivo: presentar la evidencia disponible respecto al manejo farmacológico de personas con sospecha o diagnóstico de infección respiratoria por SARS-CoV-2 (COVID-19) utilizando el método de revisiones sistemáticas rápidas (RS-R) en medicamentos poten- cialmente eficaces para su manejo. Metodología: se realizó una búsqueda sistemática y estructurada en Medline, Embase, Scopus, Cochrane Library, Clinical trials y Google Scholar en inglés. Los estudios incluidos fueron guías de práctica clínica, consensos, revisiones sistemáticas, metaanálisis, ensayos clínicos y otros estudios primarios. La búsqueda y extracción de datos se realizó por múltiples revisores, pero ninguna fue pareada. Resultados: dieciseis preguntas de interés clínico fueron resueltas, relacionadas con el uso en COVID-19 de lopinavir/ ritonavir, nelfinavir, oseltamivir, remdesivir, ribavirina, teicoplanina, umifenovir, favipiravir, tocilizumab, ivermectina y plasma convaleciente; también se evaluó el uso de medicamentos de soporte e incluidos en el manejo como la dexametasona, así como el uso concomitante de medicamentos que generaron dudas como son los AINES, los IECA y los ARA II. Conclusiones: los resúmenes de evidencia se muestran dentro del escenario de la pandemia como una buena alternativa metodológica para ofrecer información de calidad a corto plazo para los tomadores de decisiones

Resumen Introducción: la hepatitis C (HepC) representa un problema de salud pública a nivel mundial. Se estima que en Colombia la prevalencia de virus de la hepatitis C (VHC) está entre el 0,5-1 %, y asciende al 2,1 % en pacientes mayores de 50 años. La Unidad de Hepatología del Hospital Pablo Tobón Uribe (HPTU) ha sido un referente en el manejo de la HepC en Medellín y Colombia durante años. Objetivo: describir las características sociodemográficas/clínicas y los resultados en salud de los pacientes con HepC crónica atendidos en el HPTU entre 2013 y 2018. Materiales y métodos: estudio observacional, descriptivo, retrospectivo de pacientes con HepC crónica atendidos entre el 1 de enero de 2013 y el 31 de marzo de 2018. Resultados: se analizaron 108 pacientes. La edad promedio fue de 55,8 años (desviación estándar [DE] 13,7), 51,9 % eran hombres, y 78,7 % pertenecían al régimen contributivo. El mecanismo de transmisión más frecuente fue la hemotransfusión; el genotipo 1 predominó en el grupo de pacientes analizados. La efectividad de los esquemas con interferón fue del 46,9 % y de los antivirales de acción directa (AAD) del 94,6 %. La presencia de reacciones adversas a medicamentos (RAM) fue del 68,2 % en pacientes con esquemas con interferón/ribavirina y del 25,9 % en pacientes con AAD. Conclusiones: se realiza la caracterización de los pacientes atendidos en el HPTU, en quienes los AAD han mostrado mayor efectividad y seguridad en comparación con esquemas con interferón/ribavirina. Abstract Introduction: Throughout the world hepatitis C (HepC) is a public health problem. Estimates for its prevalence in Colombia range from 0.5% to 1% but 2.1 % for patients over 50 years of age. The Hepatology Unit at the Hospital Pablo Tobón Uribe (HPTU) has been a benchmark for management of HepC in Medellín and Colombia for years. Objective: To describe sociodemographic and clinical characteristics together with health outcomes of patients with chronic HepC who were treated at the HPTU between 2013 and 2018. Materials and methods: This is an observational, descriptive and retrospective study of patients with chronic HepC, treated between January 1, 2013 and March 31, 2018. Results: One hundred and eight patients were analyzed. The average age was 55.8 years (SD 13.7), 51.9% were men, and 78.7% belonged to the contributory health care scheme. Most frequently, the disease was transmitted by blood, and genotype 1 predominated in the group of patients analyzed. The effectiveness of interferon schemes was 46.9% while that of Direct-Acting Antivirals (DAA) was 94.6%. Adverse drug reactions were found in 68.2% of patients treated with interferon/ribavirin schemes but in only 25.9% of the patients treated with DAA. Conclusions: In this group of patients treated at HPTU, DAA were safer and more effective than interferon/ribavirin schemes.

Real-life cohorts have shown that the effectiveness of all-oral, direct-acting antivirals (DAA) for HCV treatment is > 90%. We aimed to explore the predictive factors of DAA success in HIV coinfection. This is an observational prospective study within the cohort BVIH-DOC^, Madrid, Spain. HIV/HCV-coinfected patients were included if they had been treated with DAAs between 9 January 2015 and 31 August 2016. The sustained virological response (SVR) was analysed in the intention-to-treat population. Binary logistic regression was used to study the impact of cirrhosis, anti-HCV therapy experience and the IL28B polymorphism on SVR, besides factors with a p value < 0.15 from the univariate analysis. DAA were prescribed to 423 patients. SVR was confirmed in 92.9%. The univariate analysis showed higher proportion of patients with SVR among those with DAA adherence ≥ 95% (difference + 10.3%, 95%CI 3.5–19.6) and a baseline CD4+ cell count ≥ 200/μL (difference + 14.7%, 95%CI 4.1–31.0). Logistic regression evinced that both DAA adherence and baseline CD4+ cell counts predicted the SVR (OR 3.9, 95% CI 1.8– 8.8, and OR 5.2, 95% CI 1.9–13.9, respectively). Moreover, men who reported having sex with other men (MSM) were less likely to achieve SVR (OR 4.2, 95% CI 1.1–16.1). Among MSM, three of three patients without SVR were suspected to have experienced HCV reinfection. DAA for HCV in HIV-coinfected patients is highly effective. DAA adherence ≥ 95% and a baseline CD4+ count ≥ 200/μL predicted a higher probability of SVR. A lower rate of SVR was found in MSM, presumably due to a higher frequency of HCV reinfection.

Resumen Aunque las bacterias son los principales patógenos involucrados en la neumonía adquirida en la comunidad, algunos virus son responsables directos o en coinfección de un importante número de neumonías adquiridas en la comunidad. La clínica de estas neumonías puede ser muy similar, en el caso de los virus afectan más frecuentemente a la población infantil y geriátrica, con frecuencia no elevan la cifra de leucocitos, la fiebre es inconstante y frecuentemente se acompañan de síntomas de vías respiratorias altas. Característicamente no elevan la procalcitonina. Durante años el diagnóstico ha recaído en cultivos celulares y en detección de antígenos; desde la incorporación en la clínica de la PCR, la identificación de estos patógenos ha aumentado, descubriéndose nuevos microorganismos como el bocavirus. En general, el virus influenza A y el virus respiratorio sincitial siguen siendo los principales virus implicados. Sin embargo, la irrupción en los últimos años de epidemias con alta letalidad de coronavirus y de zoonosis de virus influenza hace que sea necesario mostrarse alerta ante estos nuevos patógenos emergentes. Los inhibidores de la neuraminidasa para neumonías víricas han demostrado disminuir la transmisión en casos expuestos y mejorar la evolución clínica en pacientes en Cuidados Intensivos; su uso en infecciones banales no está recomendado. La ribavirina ha sido utilizada en niños con infecciones por virus respiratorio sincitial, así como en inmunodeprimidos. Fuera de estos fármacos, ningún otro antiviral ha probado su eficacia. Las medidas de prevención con vacunación para virus influenza y con anticuerpos monoclonales para virus respiratorio sincitial podrían disminuir la incidencia de neumonía.

La infección por virus influenza ocasiona importante morbilidad y mortalidad en Chile durante elperíodo de otono-invierno. La mayoría de las personas infectadas con el virus de la gripe presentan síntomas respiratorios agudos y fiebre autolimitados, sin complicaciones, o son asintomáticos. Sin embargo, enfermedad respiratoria grave y complicaciones debido a la infección viral, incluida la hospitalización y la muerte, pueden ocurrir en personas de edad avanzada, en ninos menores de dos anos, personas con condiciones médicas subyacentes (incluida la enfermedadpulmonar y cardiaca crónica, diabetes e inmunosupresión), embarazadas y en personas previamente sanas. Lapesquisa y tratamiento precoz con medicamentos antivirales (inhibidores de la neuraminidasa) puede reducir la gravedad y duración de los síntomas, riesgo de hospitalización y complicaciones (otitis media, bronquitis, neumonía), ypuede reducir el uso de los servicios de atención ambulatoria yprescripción de antibióticos, acortar el período de transmisibilidad de la infección en la comunidad y, posiblemente, la mortalidad en ciertas poblaciones de riesgo. La vacunación es el método de elección para la prevención de la gripe en la comunidad, pero los medicamentos antivirales también pueden ser utilizados como medio primario o secundario de prevención de la transmisión de la influenza en ciertos contextos epidemiológicos. Se revisan las principales recomendaciones para el diagnóstico, tratamiento y prevención de la influenza en nuestro país.

Although bacteria are the main pathogens involved in community-acquired pneumonia, a significant number of community-acquired pneumonia are caused by viruses, either directly or as part of a co-infection. The clinical picture of these different pneumonias can be very similar, but viral infection is more common in the pediatric and geriatric populations, leukocytes are not generally elevated, fever is variable, and upper respiratory tract symptoms often occur; procalcitonin levels are not generally affected. For years, the diagnosis of viral pneumonia was based on cell culture and antigen detection, but since the introduction of polymerase chain reaction techniques in the clinical setting, identification of these pathogens has increased and new microorganisms such as human bocavirus have been discovered. In general, influenza virus type A and syncytial respiratory virus are still the main pathogens involved in this entity. However, in recent years, outbreaks of deadly coronavirus and zoonotic influenza virus have demonstrated the need for constant alert in the face of new emerging pathogens. Neuraminidase inhibitors for viral pneumonia have been shown to reduce transmission in cases of exposure and to improve the clinical progress of patients in intensive care; their use in common infections is not recommended. Ribavirin has been used in children with syncytial respiratory virus, and in immunosuppressed subjects. Apart from these drugs, no antiviral has been shown to be effective. Prevention with anti-influenza virus vaccination and with monoclonal antibodies, in the case of syncytial respiratory virus, may reduce the incidence of pneumonia.

BACKGROUND Etravirine is a second-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) with reduced cross-resistance to first-generation NNRTIs. Because many perinatally HIV-infected patients have been treated with first-generation NNRTIs, they may have acquired resistance-associated mutations to etravirine (RAMe). METHODS We determined for the interval 1998-2009 the prevalence and factors associated with the presence of RAMe. RESULTS Twenty-three of 66 (34.8%) children had RAMe; the most common were 181C (19.6%), 190A (7.5%), 98G (6%), 106I (4.5%), 179D (4.5%), 100I (3%), 181I (1.5%), 138A (1.5%) and 179T (1.5%). Eleven children with RAMe (17%) had a mutation score between 2.5 and 3.5 and 1 (1.5%) a score ≥4, indicating an intermediate and reduced response to etravirine. For each 1% increase in CD4% there is a 7% decrease in the odds of RAMe (OR 0.93; 95% CI 0.88-0.97; P < 0.01). History of nevirapine use (OR 8.95; 95% CI 2.31-34.73; P < 0.01) and Hispanic ethnicity (OR 4.76; 95% CI 1.03-21.87; P = 0.04) are significantly associated with risk of RAMe. CONCLUSIONS RAMe are present and common among antiretroviral-experienced perinatally HIV-infected children without previous exposure to etravirine. This could limit the efficacy of etravirine-based regimens. In addition, our results underscore the importance of taking previous history of nevirapine into account for combined antiretroviral therapy regimens that contain etravirine.

Objectives: To describe the clinical presentation and prognosis of elderly adults hospitalized with pandemic 2009 A(H1N1) influenza infection and to compare these data with those of younger patients. Design: Prospective, observational, multicenter study. Setting: Thirteen hospitals in Spain. Participants: Adults admitted to the hospital with confirmed pandemic 2009 A(H1N1) influenza infection. Measurements: Demographic, clinical, laboratory, radiological, and outcome variables. Results: Between June 12 and November 10, 2009, 585 adults with confirmed 2009 A(H1N1) influenza were hospitalized, of whom 50 (8.5%) were aged 65 and older (median age 72, range 65�87). Older adults (?65) were more likely to have associated comorbidities (88.0% vs 51.2%; P < .001), primarily chronic pulmonary diseases (46.0% vs 27.3%; P < .001). Lower respiratory tract symptoms and signs such as dyspnea (60.0% vs 45.6%) and wheezing (46.0% vs 27.8%; P = .007) were also more common in these elderly adults, although pulmonary infiltrates were present in just 14 (28.0%) of the older adults, compared with 221 (41.3%) of the younger adults (P = .06). Multilobar involvement was less frequent in elderly adults with pulmonary infiltrates than younger adults with pulmonary infiltrates (21.4% vs 60.0%; P = .05). Rhinorrhea (4.0% vs 21.9%; P = .003), myalgias (42.0% vs 59.1%; P = .01), and sore throat (14.0% vs 29.2%; P = .02) were more frequent in younger adults. Early antiviral therapy (

Los errores en la prescripcion de medicamentos son frecuentes en escenarios ambulatorios y no hay informacion disponible sobre el uso de antivirales en el tratamiento del herpes zoster. Para conocer la dosis y oportunidad en la prescripcion de aciclovir o valaciclovir se aplico un cuestionario a 31 medicos que trabajan en hospitales o sitios de atencion primaria en Santiago y que declararon haber atendido este tipo de pacientes. El compuesto aciclovir fue mas indicado que valaciclovir (71,9 vs 28,1%) pero menos de un tercio de las prescripciones (27,3%) cumplieron simultaneamente con una dosis minima (4 g/dia) y ventanas de tiempo apropiadas de aciclovir (hasta 72 horas del rash). El reducido tamano de la muestra impidio efectuar un analisis de los factores ligados a este fenomeno. El conocimiento apropiado sobre dosis y oportunidad de aciclovir o valaciclovir fue infrecuente en un grupo de medicos que declararon atender pacientes con herpes zoster en Santiago

ResumenIntroducción. El cuadro clínico del síndrome erosivo corneal recurrente (SECR) puede ser confundido con el de la queratitis epitelial herpética.Materiales y métodosSerie de casos de SECR con diagnóstico erróneo de queratitis epitelial herpética en la que se comparan las diferencias clínicas entre ambas patologías para establecer el diagnóstico correcto y el tratamiento adecuado.ResultadosEstudio de 10 (23.8%) pacientes de un total de 42. Siete mujeres y 3 hombres con SECR, en 2 de los casos bilateral, quienes acudieron con diagnóstico erróneo de queratitis epitelial herpética. Los 10 pacientes fueron referidos o acudieron a segunda opinión por recurrencia y exacerbación sintomatológica sin respuesta a antivirales. Ambas entidades se presentan con dolor ocular, ojo rojo, lagrimeo, fotofobia, sensación de cuerpo extraño y visión borrosa.ConclusionesLos rasgos distintivos del SECR son: inicio abrupto por la noche o madrugada al despertar, antecedente de trauma corneal o distrofia corneal anterior y ausencia de leucomas corneales. La semejanza sintomatológica y el desconocimiento del SECR incrementan la posibilidad de confundir el diagnóstico.AbstractIntroductionThe signs and symptoms of recurrent corneal erosion syndrome (RCES) may be confused with those of herpetic epithelial keratitis.Materials and methodsCase series of RCES patients erroneously diagnosed as herpetic epithelial keratitis. Clinical differences were compared between both pathologies in order to establish the correct diagnosis and adequate treatment.ResultsCase series of 10 (23.8%) out of 42 patients were included in the study. Seven women and three men with RCES were initially misdiagnosed and treated as herpetic epithelial keratitis. Patients were referred for a second opinion due to poor or no response to antiviral therapy. Symptoms of both entities may consist of ocular pain, red eye, watering, photophobia, foreign body sensation, and blurred vision.ConclusionsThe distinguishing features of RCES are the sudden ocular pain at night or at awakening, history of corneal trauma, and lack of corneal leucomas. Similarity of symptomatology, plus unawareness of RCES increases the possibility of misdiagnosis.
