RESUMO

BACKGROUND: This was a substudy of a Phase IV, randomized clinical trial (ClinicalTrials.gov identifier: NCT04295460) aiming to compare the activity of dolutegravir/lamivudine versus dolutegravir plus tenofovir alafenamide/emtricitabine (DTG + TAF/FTC) in the male genital tract. METHODS: Participants were asymptomatic adults without sexually transmitted diseases, treatment-naive people living with HIV (PLWH), with CD4+ T cell counts >200 cells/mm3 and plasma HIV-1-RNA levels >5000 and <500 000 copies/mL, randomized (1:1) to DTG + TAF/FTC or dolutegravir/lamivudine. Blood plasma (BP) and seminal plasma (SP) were collected at baseline and Weeks 4, 8, 12 and 24. HIV-1-RNA was measured in BP and SP using the Cobas 6800 system (Roche Diagnostics) with a lower detection limit of 20 copies/mL. The primary efficacy endpoint was the proportion of subjects with undetectable SP HIV-1-RNA at Week 12 by intention-to-treat analysis. RESULTS: Fifteen participants in the DTG + TAF/FTC and 16 in the dolutegravir/lamivudine arms were analysed, with basal SP viral load of 4.81 (4.30-5.43) and 4.76 (4.09-5.23), P = 0.469, respectively. At Week 12, only one participant in each treatment arm had a detectable SP HIV-1-RNA (DTG + TAF/FTC, 141 copies/mL; dolutegravir/lamivudine, 61 copies/mL). Based on the estimated means, there was no significant difference in the decay of HIV-1-RNA in both BP and SP over time between the two arms of treatment (F = 0.452, P = 0.662, and F = 1.147, P = 0.185, respectively). CONCLUSIONS: After 12 weeks of treatment, there were no differences in the percentage of undetectable SP HIV-1-RNA in naive PLWH who started dolutegravir/lamivudine compared with DTG + TAF/FTC.

RESUMO

BACKGROUND: People living with HIV have an increased risk of anal cancer. OBJECTIVE: To estimate anal cancer incidence and related risk factors in a national cohort of HIV-infected patients. DESIGN: Prospective multicenter cohort study. SETTINGS: Multicenter study including patients from the Spanish HIV Research Network. PATIENTS: We collected data from 16,274 HIV-infected treatment-naive adults recruited from January 2004 to November 2020. MAIN OUTCOMES MEASURES: The primary outcome measures of this study were the incidence and prevalence of anal carcinoma. The secondary outcome measures included the associations between baseline and time-dependent covariables and the primary end point. RESULTS: Twenty-six cases of anal cancer were diagnosed, 22 of which were incident cases resulting in a cumulative incidence of 22.29 of 100,000 person-years, which was stable during the study period. At the end of the study, 20 of the 43 centers had screening programs for high-grade anal dysplasia. Patients with anal cancer were males (26/26; 100% vs 13,833/16,248; 85.1%), were mostly men who have sex with men (23/26; 88.5% vs 10,017/16,248; 61.6%), had a median age of 43 years (interquartile range, 35-51), were more frequently previously diagnosed with an AIDS-defining illness (9/26; 34.6% vs 2429/16,248; 15%), and had lower nadir CD4 cell counts (115 vs 303 µL). About a third (34.6%, 9/26) were younger than 35 years. In multivariable analysis, men who have sex with men and patients with previous AIDS-defining illness had an 8.3-fold (95% CI, 1.9-36.3) and 2.7-fold (95% CI, 1.1-6.6) increased HR for developing anal cancer, respectively. Patients with higher CD4 cell counts during the follow-up showed a 28% lower risk per each additional 100 CD4 cell/µL (95% CI, 41%-22%). LIMITATIONS: Lack of information on some potential risk factors, screening, and treatment of high-grade anal dysplasia were not uniformly initiated across centers during the study period. CONCLUSIONS: Although the overall incidence in our study was low, there was a significant number of patients younger than 35 years with anal cancer. In addition to age, other factors, such as men who have sex with men and patients with severe immunosuppression (current or past), should be prioritized for anal cancer screening. INCIDENCIA DEL CNCER DE ANO Y LOS FACTORES DE RIESGO RELACIONADOS CON PACIENTES INFECTADOS POR VIH INCLUIDOS EN LA COHORTE PROSPECTIVA NACIONAL ESPAOLA CORIS: ANTECEDENTES:Las personas portadoras del virus de la inmunodeficiencia humana tienen un mayor riesgo de cáncer anal.OBJETIVO:Nosotros queremos estimar la incidencia de cáncer anal y los factores de riesgo relacionados en una cohorte nacional española de pacientes infectados por VIH.DISEÑO:Estudio de cohortes de tipo multicéntrico y prospectivo.ÁMBITO:Se incluyeron pacientes de la Red Española de Investigación en VIH.PACIENTES:Recolectamos los datos de 16,274 adultos infectados por el VIH que nunca habían recibido tratamiento, reclutados desde enero de 2004 hasta noviembre de 2020.MEDIDAS DE RESULTADO PRINCIPALES:Las medidas de resultado primarias de este estudio fueron la incidencia y la prevalencia del carcinoma anal. Las medidas de resultado secundarias incluyeron las asociaciones entre las covariables basales y dependientes del tiempo y el criterio principal de valoración.RESULTADOS:Se diagnosticaron 26 casos de cáncer anal, de los cuales 22 fueron casos incidentales resultando con una incidencia acumulada de 22,29/100.000 personas-año que se mantuvo estable durante el período de estudio.Al final de nuestro estudio, 20 de los 43 centros referentes tenían programas de detección de displasia anal de alto grado. Los pacientes con cáncer anal eran hombres (26/26; 100% vs 13 833/16 248; 85,1%), en su mayoría hombres que mantenían sexo con otros hombres (23/26; 88,5% vs 10 017/16 248; 61,6%), la mediana de edad fue de 43 años (IQR: 3 -51), 34,6% (9/26) < 35 años, previa y frecuentemente diagnosticados con una enfermedad definitoria de SIDA (9/26; 34,6% vs 2429/16248; 15%) y que tenían un punto opuesto mucho más bajo en el recuentos de células CD4 (115 µL frente a 303 µL).En el análisis multivariable, los hombres que tenían relaciones sexuales con otros hombres y los pacientes con enfermedades definitorias de sida anteriores, tenían un aumento de 8,3 veces (IC del 95%: 1,9 a 36,3) y de 2,7 veces (IC del 95%: 1,1 a 6,6) en el cociente de riesgos instantáneos para desarrollar cáncer anal, respectivamente. Los pacientes con recuentos de células CD4 más altos durante el seguimiento mostraron un riesgo 28 % menor por cada 100 células CD4/µl adicionales (95% IC: 41%- 22%).LIMITACIONES:La falta de información sobre algunos factores potenciales de riesgo, la detección y el tratamiento de la displasia anal de alto grado no se iniciaron uniformemente en todos los centros durante el período de estudio.CONCLUSIONES:Si bien la incidencia general en nuestro estudio fue baja, hubo un número significativo de pacientes de <35 años con cáncer anal. Además de la edad, otros factores como los hombres que tienen sexo con hombres y los pacientes con inmunosupresión severa (actual o pasada) deben priorizarse para la detección del cáncer anal.

RESUMO

BACKGROUND: Anal squamous cell carcinoma is rare, in general, but considerably higher in HIV-infected men who have sex with men. There is no consensus on the screening of at-risk populations. OBJECTIVE: This study aimed to determine the incidence rates of anal squamous cell carcinoma and the efficacy of a screening program. DESIGN: This is a cohort study (SeVIHanal/NCT03713229). SETTING: This study was conducted at an HIV outpatient clinic in Seville, Spain. PATIENTS: From 2004 to 2017, all patients with at least 1 follow-up visit were analyzed (follow-up group), including a subgroup of men who have sex with men who participated in a specialized program for screening and treating anal neoplasia (SCAN group) from 2011 onward. MAIN OUTCOME MEASURES: The primary outcome measure was the incidence rate of anal squamous cell carcinoma. RESULTS: Of the 3878 people living with HIV included in the follow-up group, 897 were transferred to the SCAN group; 1584 (41%) were men who have sex with men. Total follow-up was 29,228 person-years with an overall incidence rate for anal squamous cell carcinoma of 68.4/100,000 person-years (95% CI, 46.7-97.4). The changes in the incidence rate/100,000 person-years (95% CI) over time was 20.7 (3.40-80.5) for 2004 to 2006, 37.3 (13.4-87.3) for 2007 to 2010, and 97.8 (63.8-144.9) for 2011 to 2017 (p < 0.001). The strongest impact on the incidence of anal squamous cell carcinoma was made by the lack of immune restoration (adjusted incidence rate ratio (95% CI): 6.59 (4.24-10); p < 0.001), the Centers for Disease Control and Prevention category C (adjusted incidence rate ratio (95% CI): 7.49 (5.69-9.85); p < 0.001), and non-men who have sex with men (adjusted incidence rate ratio (95% CI): 0.07 (0.05-0.10); p < 0.001) in a Poisson analysis. From 2010 to 2017, incidence rates (95% CI) of anal squamous cell carcinoma within the SCAN group and the men who have sex with men of the follow-up group were 95.7 (39.6-202) and 201 (101-386)/100,000 person-years (adjusted incidence rate ratio (95% CI): 0.30 (0.23-0.39); p<0.001). The incidence rate ratio (95% CI) including non-men who have sex with men in the follow-up group was 0.87 (0.69-1.11); p = 0.269. LIMITATIONS: Adherence to the visits could not be quantified. CONCLUSION: Incidence rates of anal squamous cell carcinoma in people living with HIV increased significantly from 2004 to 2017, especially in men who have sex with men who were not being screened. Participation in the SCAN program significantly reduced the incidence of anal squamous cell carcinoma in men who have sex with men, in whom focus should be placed, especially on those presenting with Centers for Disease Control and Prevention category C and advanced immune suppression.

TASA DE INCIDENCIA Y FACTORES DE RIESGO DEL CARCINOMA ANAL A CLULAS ESCAMOSAS EN UNA COHORTE DE PERSONAS QUE VIVEN CON EL VIH DE A IMPLEMENTACIN DE UN PROGRAMA DE DETECCIN: ANTECEDENTES:El carcinoma anal a células escamosas es generalmente raro, pero considerablemente más alto en hombres infectados por el VIH que tienen relaciones sexuales con hombres. No hay consenso sobre el cribado de poblaciones en riesgo.OBJETIVO:Este estudio tuvo como objetivo determinar las tasas de incidencia del carcinoma anal a células escamosas y la eficacia de un programa de detección.DISEÑO:Estudio de cohorte (SeVIHanal / NCT03713229).AJUSTE:Clínica ambulatoria de VIH en Sevilla, España.PACIENTES:De 2004 a 2017, se analizaron todos los pacientes con al menos una visita de seguimiento (grupo F / U), incluido un subgrupo de hombres que tenían relaciones sexuales con hombres que participaron en un programa especializado de cribado y tratamiento de neoplasias anales (SCAN-group) a partir de 2011.PRINCIPALES MEDIDAS DE RESULTADO:Tasas de incidencia del carcinoma anal a células escamosas.RESULTADOS:De las 3878 personas que viven con el VIH incluidas en el grupo F / U, 897 fueron transferidas al grupo SCAN, 1584 (41%) eran hombres que tenían relaciones sexuales con hombres. El seguimiento total fue de 29228 personas-año con una tasa de incidencia general de carcinoma anal a células escamosas de 68,4 / 100000 personas-año [intervalo de confianza del 95%: 46,7-97,4]. El cambio en las tasas de incidencia / 100000 personas-año (intervalo de confianza del 95%) a lo largo del tiempo fue 20,7 (3,40-80,5) para 2004-2006, 37,3 (13,4-87,3) para 2007-2010 y 97,8 (63,8-144,9) para 2011-2017, p <0,001. El impacto más fuerte en la incidencia del carcinoma a células escamosas anal fue la falta de restauración inmunológica [índice de tasa de incidencia ajustado (intervalo de confianza del 95%): 6,59 (4,24-10); p <0,001], categoría C de los Centros de Control de Enfermedades [índice de tasa de incidencia ajustado (intervalo de confianza del 95%): 7,49 (5,69-9,85); p <0,001] y no hombres que tenían relaciones sexuales con hombres [razón de tasa de incidencia ajustada (intervalo de confianza del 95%): 0,07 (0,05-0,10); p <0,001] en el análisis de Poisson. Desde 2010-2017, las tasas de incidencia (intervalo de confianza del 95%) de carcinoma anal a células escamosas dentro del grupo SCAN y los hombres que tienen relaciones sexuales con hombres del grupo F / U fueron 95,7 (39,6-202) y 201 (101- 386) / 100000 personas-año [razón de tasa de incidencia ajustada (intervalo de confianza del 95%): 0,30 (0,23-0,39); p <0,001]. La razón de la tasa de incidencia (intervalo de confianza del 95%), incluidos los no hombres que tenían relaciones sexuales con hombres en F / U, fue de 0,87 [0,69-1,11); p = 0,269].LIMITACIONES:No se pudo cuantificar la adherencia a las visitas.CONCLUSIÓNES:La tasa de incidencia del carcinoma anal a células escamosas en personas que viven con el VIH aumentó significativamente de 2004 a 2017, especialmente en hombres que tenían relaciones sexuales con hombres que no se someten a pruebas de detección. La participación en el programa SCAN redujo significativamente la incidencia de carcinoma anal a células escamosas en hombres que tenían relaciones sexuales con hombres, en quienes se debe prestar una especial atención, sobre todo en aquellos que se presentan en la categoría C de los Centros de Control de Enfermedades con inmunodeficiencia avanzada.

RESUMO

Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components. Dendritic cells (DCs) play a key role in the defense against viral infections, for instance plasmacytoid DCs (pDCs), have the capacity to produce vast amounts of interferon-alpha (IFN-α). In COVID-19 there is a deficit in DC numbers and IFN-α production, which has been associated with disease severity. In this work, we described that in addition to the DC deficiency, several DC activation and homing markers were altered in acute COVID-19 patients, which were associated with multiple inflammatory markers. Remarkably, previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+ myeloid DCs and pDCs seven months after SARS-CoV-2 infection. Moreover, the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients, while no restoration of integrin ß7 and indoleamine 2,3-dyoxigenase (IDO) levels were observed. These findings contribute to a better understanding of the immunological sequelae of COVID-19.

RESUMO

Introduction: The use of systemic corticosteroids in severely ill patients with coronavirus disease 2019 (COVID-19) is controversial. We aimed to evaluate the efficacy and safety of corticosteroid pulses in patients with COVID-19 pneumonia. Methods: A quasi-experimental study, before and after, was performed in a tertiary referral hospital, including admitted patients showing COVID-19-associated pneumonia. The standard treatment protocol included targeted COVID-19 antiviral therapy from 23rd March 2020, and additionally pulses of methylprednisolone from 30th March 2020. The primary outcome was a composite endpoint combining oro-tracheal intubation (OTI) and death within 7 days. Results: A total of 24 patients were included. Standard of care (SOC) (before intervention) was prescribed in 14 patients, while 10 received SOC plus pulses of methylprednisolone (after intervention). The median age of patients was 64.5 years and 83.3% of the patients were men. The primary composite endpoint occurred in 13 patients (92.9%) who received SOC vs. 2 patients (20%) that received pulses of methylprednisolone (odds ratio, 0.02; 95% confidence interval, 0.001 to 0.25; p = 0.019). Length of hospitalization in survivors was shorter in the corticosteroids group (median, 14.5 [8.5-21.8] days vs. 29 [23-31] days, p = 0.003). There were no differences in the development of infections between both groups. There were 3 deaths, none of them in the corticosteroids group. Conclusions: In patients with severe pneumonia due to COVID-19, the administration of methylprednisolone pulses was associated with a lower rate of OTI and/or death and a shorter hospitalization episode.


Introducción: El uso de corticosteroides sistémicos en pacientes gravemente enfermos por enfermedad coronavírica de 2019 (covid-19) es controvertido. Nuestro objetivo fue evaluar la eficacia y la seguridad de los pulsos de corticoesteroides en los pacientes con neumonía por covid-19. Métodos: Se realizó un ensayo cuasiexperimental, tipo antes y después, en un hospital terciario de referencia que incluyó a pacientes ingresados por neumonía asociada a covid-19. El protocolo de tratamiento estándar incluía un tratamiento antiviral dirigido contra el virus de la covid-19 desde el 23 de marzo de 2020 y añadió pulsos de metilprednisolona desde el 30 de marzo de 2020. El resultado primario fue un criterio combinado compuesto por la intubación orotraqueal y el fallecimiento durante los siguientes siete días. Resultados: Se incluyó un total de 24 pacientes. El protocolo de tratamiento (antes de la intervención) se prescribió en 14 pacientes, mientras que 10 recibieron el protocolo de tratamiento además de los pulsos de metilprednisolona (después de la intervención). La edad media de los pacientes fue de 64,5 años y el 83,3% de los pacientes eran hombres. El resultado combinado primario tuvo lugar en 13 pacientes (92,9%) que recibieron el protocolo de tratamiento frente a 2 pacientes (20%) que recibieron los pulsos de metilprednisolona (odds ratio = 0,02; intervalo de confianza del 95% = 0,001-0,25; p = 0,019). La duración de la hospitalización en los supervivientes fue más corta en el grupo que recibió corticoesteroides (media = 14,5 [8,5-21,8] días frente a 29 [23-31] días, p = 0,003). No hubo diferencias en el desarrollo de infecciones entre ambos grupos. Hubo tres fallecimientos, ninguno de ellos en el grupo que recibió corticoesteroides. Conclusiones: En los pacientes con neumonía grave por covid-19, la administración de pulsos de metilprednisolona se asoció a unas tasas menores de intubación orotraqueal y/o muerte y a episodios de hospitalización más cortos.

RESUMO

Almost half of new diagnoses of human immunodeficiency virus (HIV) infection are made late, leading to increased morbidity and mortality, greater spread of infection, and higher public health care costs. Emergency services care for many patients who share behaviors associated with HIV transmission risk who arrive in clinical situations that are associated with HIV infection. A strategy to increase the rates of early diagnosis by promoting serology for HIV when caring for patients with certain clinical profiles might therefore be the key to improvement. This approach is hardly used at present, however, unless the result of serology would change the management of the acute complaint that led to the visit. These recommendations based on evidence from a search and review of recent publications were developed by a group of experts appointed by the Spanish Society of Emergency Medicine (SEMES). The resulting statement aims to support decision-making by emergency physicians and promote HIV screening and referral to appropriate specialists for follow-up in patients with certain conditions (sexually transmitted infections, herpes zoster, community-acquired pneumonia) or reporting certain scenarios (practice of chemsex, need for post-exposure prophylaxis). These 6 settings were selected because they are often seen in emergency departments and are common in patients with HIV-positive tests. The recommendations address when to order serology for HIV and how to manage the referral process. Included are decision-making tools for emergency physicians.


Casi la mitad de los nuevos diagnósticos de infección por el virus de la inmunodeficiencia humana (VIH) se realizan de forma tardía, lo cual provoca un aumento en la morbimortalidad, una mayor expansión de la epidemia y un incremento en los costes sanitarios públicos. En los servicios de urgencias se atiende a muchos de los pacientes que presentan situaciones indicadoras de infección por VIH o que comparten su misma vía de transmisión. Por lo tanto, pueden ser clave en una estrategia que mejore las tasas de diagnóstico precoz mediante la promoción de la solicitud de serologías frente al VIH durante la atención de determinados perfiles clínicos. Sin embargo, esto en la actualidad se produce escasamente a no ser que el resultado de la serología vaya a modificar el manejo del proceso agudo que ha motivado la consulta en urgencias. Las presentes recomendaciones se han desarrollado por un grupo de expertos designados por la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES) en base a la identificación y revisión de la evidencia científica más reciente. El objetivo de este documento es dar soporte a los médicos de urgencias en la toma de decisiones, promoviendo el cribado del VIH y la derivación de los pacientes al especialista adecuado para su seguimiento posterior en seis entidades clínicas seleccionadas por su elevada prevalencia en pacientes VIH positivos y la alta frecuencia con la que son atendidas en urgencias: 1) infecciones de transmisión sexual; 2) profilaxis post exposición; 3) herpes zoster; 4) práctica del chemsex; 5) neumonía adquirida en la comunidad, y 6) síndrome mononucleósico. Las recomendaciones incluyen indicaciones sobre en qué pacientes debe realizarse una serología, el proceso de derivación y herramientas para ayudar a los médicos de urgencias en la toma de decisiones.

RESUMO

BACKGROUND: Screening methods for anal squamous intraepithelial lesions (SILs) are suboptimal. We aimed to determine the diagnostic performance of a composite endpoint comprising anal liquid-based cytology (aLBC) and high-risk human papillomavirus (HR-HPV) testing to predict histological high-grade SILs (hHSILs). METHODS: From the SeVIHanal cohort, human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) who had an aLBC with concomitant HR-HPV testing were included. hHSILs were determined by high-resolution anoscopy (HRA)-guided biopsy. RESULTS: A total of 705 visits obtained from 426 patients were included. The prevalence of HR-HPV among aLBC results were 51.9% (133/215) normal, 87.9% (20/232) low-grade SILs (LSILs), and 90.9% (149/164) high-grade SILs; P (linear association) < .001. Low prevalence of hHSILs was only observed for the composite aLBC/HR-HPV testing endpoint "normal/noHR-HPV" (10%) and "LSIL/noHR-HPV" (4%). The prognostic values (95% confidence interval) for HR-HPV to predict hHSILs in normal cytology were positive predictive value (PPV), 29.3% (25.6%-33.3%); negative predictive value (NPV), 90.2% (82.8%-94.7%); sensitivity, 83% (69.2%-92.4%); and specificity, 44.1% (36.4%-51.9%). Corresponding figures for cytologic LSILs were PPV, 39.2% (37.4%-41.1%); NPV, 96.4% (78.9%-99.5%); sensitivity, 98.8% (93.3%-99.9%); and specificity, 17.9% (12.1%-24.9%). A positive interaction and a synergistic effect for the composite endpoint were observed (relative excess risk = 1.50, attributable proportion of histological results to interaction = 0.17, synergy index = 1.24). CONCLUSIONS: HRA should not be indicated in the setting of LSILs/noHR-HPV following aLBC-based screening. In contrast, HIV-infected MSM with normal aLBC/HR-HPV infection should be considered for HRA.

RESUMO

OBJECTIVE: To determine the required learning time for high-resolution anoscopy (HRA)-guided biopsy to detect histological high-risk squamous intraepithelial lesions (hHSIL) and to identify factors that impact on the training process. METHODS: All HIV-infected, screening-naïve men-who-have-sex-with-men who underwent HRA conducted by one single observer from 2010 to 2017 in a Spanish HIV-outpatient clinic were analysed. RESULTS: Eighty-five (14.7%) of the 581 patients included presented hHSIL. The factors associated with the capacity to detect hHSIL [adjusted odds ratio (aOR), 95% confidence interval (95%CI)] were the presence of cytological HSIL (3.04, 1.78-5.21; p < 0.001), infection with high-risk human papilloma virus (HR-HPV) (2.89, 1.38-6.05; p = 0.005), the number of biopsies taken/HRA (aOR: 1.28, 1.07-1.52; p = 0.006) and tobacco smoking (1.75; 1.12-2.73; p = 0.014). Two events independently augmented the detection rate of hHSIL: one single experienced pathologist interpreted biopsies after 409 HRA (2.80, 1.74-4.48; p = 0.035) and the anoscopist underwent an additional training after 536 HRA (2.57, 1.07-6.16; p = 0.035). A learning process could be observed throughout the whole study with stable HR-HPV prevalence. CONCLUSION: The data support the growing evidence that the proposed training volume of 50-200 performances is underestimated. Extensive training of both anoscopist and pathologist is warranted and the development of tools to support the diagnostic performance may be considered.
