Pre-exposure prophylaxis program in the Community of Madrid: Two years of experience.

INTRODUCTION: Pre-exposure prophylaxis (PrEP) against the human immunodeficiency virus (HIV) is an effective and safe preventive measure. However, it has not reached all target users who could benefit from it. The study aimed to understand the sociodemographic, clinical and behavioral baseline characteristics of PrEP users. As a secondary objective, the use of concomitant medication and drug consumption were described. METHODOLOGY: Observational, retrospective and descriptive study of the sociodemographic, clinical and behavioral characteristics of the users who were included in the PrEP program of the Community of Madrid during the first two years of experience. RESULTS: Two thousand two hundred fifty-six PrEP users were included, 99.0% men, with a mean age of 36.9 years (SD 8.68). 33.1% presented a sexually transmitted infection (STI) on the first visit, highlighting chlamydiasis and rectal gonococci. 70.4% reported using drugs associated with sex, and 42.4% participated in chemsex sessions in the last 3 months. A high percentage of users with concomitant medication was observed (37.6%), highlighting drugs related to mental health and alopecia. CONCLUSIONS: A multidisciplinary approach is required to cover all the needs of PrEP users, including mental health evaluation measures and addiction treatment with the clinical approach.

Concepciones de usuarios sobre nuevas vías de administración de profilaxis pre-exposición para el VIH / Users' expectations of the new pre-exposure prophylaxis for the HIV modalities

Resumen Este artículo tiene como objetivo discutir las concepciones de los Hombres Gay, Hombres Bisexuales y una Mujer Transgénero que usan o quieren usar profilaxis previa a la exposición por el virus de la inmunodeficiencia humana oral (PrEP) sobre nuevas vías de administración. Fueron entrevistados 17 usuarios del BCN Checkpoint. Las entrevistas fueron grabadas en audio, sometidas a análisis categorial temático teniendo en cuenta la perspectiva praxeográfica. Todos están adaptados al uso de la PrEP diaria y a demanda. En relación con las nuevas vías de administración (PrEP inyección intramuscular cada dos meses; pastilla mensual; inyección subcutánea cada seis meses) todos son muy receptivos a esas posibilidades, pero les falta información sobre las especificidades de cada una de ellas y una evaluación específica de sus necesidades. Tanto la satisfacción con el uso de PrEP oral, como las expectativas sobre las nuevas vías de administración son positivas. Sin embargo, lo más importante para los/a entrevistados/a es la garantía de que tendrán seguimiento para continuar cuidando de la salud afectivo-sexual, lo que no depende del tipo de vía de administración.

Abstract This article aims to discuss the expectations of Homosexual Men, Bisexual Men and a Transgender Woman, who use or want to use an oral pre-exposure prophylaxis (PrEP) for the human immunodeficiency virus (HIV) about PrEP modalities. Sixteen PrEP users, who are followed up in the BCN Checkpoint, were interviewed,. The interviews were audio-recorded, subjected to thematic categorical analysis within the theoretical framework from the praxiographic perspective. They are all adapted to the use of daily oral and event-based PrEP. In relation to the new PrEP modalities (monthly pill; intramuscular injection every two months; subcutaneous injection every six months), they are all very receptive to these possibilities, but they lack information on the specificities of each and specific assessment of their needs. Comments about the use of oral PrEP are positive, and expectations regarding the new PrEP modalities are visibly high. However, the most important thing for the interviewees is the guarantee that they will have follow-up appointments to continue taking care of their affective-sexual health, which is not dependent on the type of PrEP modalities.

Antibody persistence 7 years after hepatitis-A vaccine in children with human immunodeficiency virus infection.

BACKGROUND: HIV-infected children have a higher risk of presenting infections, including the hepatitis A virus (HAV). The inactivated HAV vaccine is immunogenic in immunocompetent hosts; however, there are insufficient studies on the duration of seroprotection in HIV-infected children. METHODS: An analytical cohort study was conducted. HIV-1-infected children who received the inactivated HAV vaccine (2 doses) were included. Blood samples were taken for antibody measurement, the first one 28 days after the second dose and another 7 years after the vaccination schedule. Information on viral load, immunological category, weight, height, and response to antiretroviral treatment from diagnosis to the last assessment was obtained. RESULTS: 19 patients were included, with a mean age of 12.6 years (SD ± 2.29). 58% were male. 80% of the patients presented protective immunoglobulin G antibodies against HAV 7-year post-vaccination. The antibody concentration was found to be between 13 and 80 mIU/mL (median of 80 mIU/mL). 52% showed some degree of immunosuppression. There was no statistically significant relationship between the presence of seroprotection and viral load, treatment failure, immunological category, and malnutrition. Twelve patients presented with antiretroviral treatment failure, and in 33% of them, the antibodies did not offer satisfactory seroprotection. CONCLUSION: 7-year post-vaccination, 80% of HIV-infected children maintain seroprotection titers against HAV.

INTRODUCCIÓN: Los niños infectados por el virus de la inmunodeficiencia humana (VIH) tienen mayor riesgo de presentar infecciones, incluyendo hepatitis por virus A (VHA). La vacuna inactivada contra el VHA es inmunógena en el huésped inmunocompetente. No hay estudios suficientes sobre el tiempo de seroprotección en niños infectados por el VIH. MÉTODO: Estudio de cohorte, analítico. Se incluyeron niños con infección por VIH-1 que recibieron la vacuna inactivada contra el VHA (dos dosis). Se les tomaron muestras sanguíneas para medición de anticuerpos, una 28 días después de la segunda dosis y otra 7 años después del esquema de vacunación. Se obtuvo información de carga viral, categoría inmunológica, peso y talla, y respuesta al tratamiento antirretroviral desde el diagnóstico hasta la última valoración. RESULTADOS: Se incluyeron 19 pacientes con una edad media de 12.6 años (± 2.29). El 58% fueron del sexo masculino. El 80% de los pacientes presentaron anticuerpos immunoglobulin G (IgG) contra el VHA protectores a los 7 años de la vacunación. La concentración de anticuerpos se encontró entre 13 y 80 mUI/ml (mediana: 80 mUI/ml). El 52% mostraron algún grado de inmunosupresión. No existe relación estadísticamente significativa entre la presencia de seroprotección y la carga viral, la falla al tratamiento, la categoría inmunológica ni la desnutrición. Doce pacientes presentaron falla al tratamiento antirretroviral; en el 33% de ellos los anticuerpos no ofrecían seroprotección satisfactoria. CONCLUSIONES: A 7 años posvacunación, el 80% de los niños con VIH mantienen títulos de seroprotección frente al VHA.

Evaluation of a HIV screening strategy in the hospital setting to reduce undiagnosed infection.

INTRODUCTION: In Spain, half of new HIV diagnoses are late and a significant proportion of people living with HIV have not yet been diagnosed. Our aim was to evaluate the effectiveness of an automated opportunistic HIV screening strategy in the hospital setting. METHODS: Between April 2022 and September 2023, HIV testing was performed on all patients in whom a hospital admission analytical profile, a pre-surgical profile and several pre-designed serological profiles (fever of unknown origin, pneumonia, mononucleosis, hepatitis, infection of sexual transmission, rash, endocarditis and myopericarditis) was requested. A circuit was started to refer patients the specialists. RESULTS: 6407 HIV tests included in the profiles were performed and 18 (0.3%) new cases were diagnosed (26.4% of diagnoses in the health area). Five patients were diagnosed by hospital admission and pre-surgery profile and 13 by a serological profile requested for indicator entities (fever of unknown origin, sexually transmitted infection, mononucleosis) or possibly associated (pneumonia) with HIV occult infection. Recent infection was documented in 5 (27.8%) patients and late diagnosis in 9 (50.0%), of whom 5 (55.5%) had previously missed the opportunity to be diagnosed. CONCLUSIONS: This opportunistic screening was profitable since the positive rate of 0.3% is cost-effective and allowed a quarter of new diagnoses to be made, so it seems a good strategy that contributes to reducing hidden infection and late diagnosis.

Analysis of the reasons for requesting HIV serology in the emergency department other than those defined in the targeted screening strategy of the "Urgències VIHgila" program and its potential inclusion in a future consensus document.

OBJECTIVE: To describe other reasons for requesting HIV serology in emergency departments (ED) other than the 6 defined in the SEMES-GESIDA consensus document (DC-SEMES-GESIDA) and to analyze whether it would be efficient to include any of them in the future. METHODS: Review of all HIV serologies performed during 2 years in 20 Catalan EDs. Serologies requested for reasons not defined by the DC-SEMES-GESIDA were grouped by common conditions, the prevalence (IC95%) of seropositivity for each condition was calculated, and those whose 95% confidence lower limit was >0.1% were considered efficient. Sensitivity analysis considered that serology would have been performed on 20% of cases attended and the remaining 80% would have been seronegative. RESULTS: There were 8044 serologies performed for 248 conditions not recommended by DC-SEMES-GESIDA, in 17 there were seropositive, and in 12 the performance of HIV serology would be efficient. The highest prevalence of detection corresponded to patients from endemic countries (7.41%, 0.91-24.3), lymphopenia (4.76%, 0.12-23.8), plateletopenia (4.37%, 1.20-10.9), adenopathy (3.45%, 0.42-11.9), meningoencephalitis (3.12%, 0.38-10.8) and drug use (2.50%, 0.68-6.28). Sensitivity analysis confirmed efficiency in 6 of them: endemic country origin, plateletopenia, drug abuse, toxic syndrome, behavioral-confusional disorder-agitation and fever of unknown origin. CONCLUSION: The DC-SEMES-GESIDA targeted HIV screening strategy in the ED could efficiently include other circumstances not previously considered; the most cost-effective would be origin from an endemic country, plateletopenia, drug abuse, toxic syndrome, behavioral-confusional-agitation disorder and fever of unknown origin.

HIV and childhood tuberculosis: fragmentation of the flow of information in the countryside of the state of São Paulo / HIV e tuberculose infantil: a fragmentação do fluxo de informação no interior paulista / VIH y tuberculosis infantil: la fragmentación del flujo de información en el interior del estado de São Paulo

Background and objectives: children are still affected by HIV and tuberculosis (TB). This study aimed to identify the occurrence of HIV and TB cases in children. Methods: this is an epidemiological, non-experimental, retrospective study, in which the population was made up of records of HIV and TB cases in children living in a municipality in the countryside of the state of São Paulo, from 2012 to 2022, in the age group of zero to 13 years old. After data collection, data consistency and validity was checked, followed by categorization of information for descriptive analyses and presentation in absolute and relative frequency tables. Results: during the study period, six HIV cases and seven TB cases were identified in children with a respective average annual incidence of 0.033 and 0.031 cases/1,000 inhabitants aged up to 13 years. There were 146 notifications of HIV-exposed children. There was a difference of months to years between the dates of diagnosis and notification, which deviates from the Ministry of Health recommendations. Incompatibility was found between municipal and state registration platforms, which shows a breakdown in flow of information on notifications. Conclusion: there have been HIV and childhood TB cases in the last ten years. Structural problems were identified in the fragmentation of the flow of information that subsidizes health actions according to the population's needs, which overshadows the health system's ability to respond.(AU)

Justificativa e Objetivos: crianças ainda são afetadas pelo HIV e pela tuberculose (TB). Dessa forma, o objetivo do estudo foi identificar a ocorrência de casos de HIV e TB em crianças. Métodos: trata-se de estudo epidemiológico, não experimental, retrospectivo, em que a população foi constituída pelo registro de casos infantis de HIV e TB residentes em um município do interior do estado de São Paulo, no período de 2012 a 2022, na faixa etária de zero a 13 anos de idade. Após a coleta de dados, foi realizada a verificação de consistência e validade dos dados, seguida do tratamento categorizado das informações para análises descritivas e apresentação em tabelas de frequência absoluta e relativa. Resultados: no período de estudo, foram identificados seis casos de HIV e sete de TB em crianças com média anual respectiva de 0,033 e 0,031 casos/1.000 habitantes com idade até 13 anos. Verificaram-se 146 notificações de criança exposta ao HIV. Houve diferença de meses a anos entre as datas de diagnóstico e de notificação, o que diverge do recomendado pelo Ministério da Saúde. Foi verificada a incompatibilidade entre plataformas de registro de âmbito municipal e estadual, o que evidencia uma quebra do fluxo de informação das notificações. Conclusão: houve ocorrência de casos de HIV e TB infantil nos últimos dez anos. Foram identificados problemas estruturais na fragmentação do fluxo da informação que subsidia ações de saúde de acordo com as necessidades da população, o que ofusca a capacidade de resposta do sistema de saúde.(AU)

Antecedentes y Objetivos: los niños siguen estando afectados por el VIH y la tuberculosis (TB). El objetivo de este estudio fue identificar la ocurrencia de casos de VIH y TB en niños. Métodos: se trata de un estudio epidemiológico, no experimental, retrospectivo, en el cual la población fue constituida por los registros de casos de VIH y TB en niños residentes en un municipio del interior del estado de São Paulo entre 2012 y 2022, con edad entre cero y 13 años. Después de la recolección de datos, se verificó la consistencia y validez de los mismos, seguido del tratamiento categorizado de la información para análisis descriptivos y presentación en tablas de frecuencias absolutas y relativas. Resultados: durante el periodo de estudio, se identificaron seis casos de VIH y siete de TB en niños, con una incidencia media anual respectiva de 0,033 y 0,031 casos/1.000 habitantes de hasta 13 años. Hubo 146 notificaciones de niños expuestos al VIH. Hubo una diferencia de meses a años entre las fechas de diagnóstico y notificación, lo que se desvía de lo recomendado por el Ministerio de Salud. Hubo incompatibilidad entre las plataformas de registro municipal y estatal, lo que muestra una ruptura en el flujo de información sobre las notificaciones. Conclusión: se han registrado casos de VIH y de tuberculosis infantil en los últimos diez años. Se identificaron problemas estructurales en la fragmentación del flujo de información que subvenciona las acciones sanitarias según las necesidades de la población, lo que ensombrece la capacidad de respuesta del sistema sanitario.(AU)

Epidemiological profile of individuals with HIV/Aids in a municipality in Maranhão State, Brazil, from 2017 to 2020 / Perfil epidemiológico de individuos con VIH/SIDA en municipio en Maranhão, Brasil, de 2017 a 2020 / Perfil epidemiológico de indivíduos com HIV/Aids em município no Maranhão, Brasil, de 2017 a 2020

Background and Objective: To understand the main forms of transmission of HIV in order to foster the containment of the transmission chain, early diagnosis and the epidemiological profile of patients. In this sense, it will enable the analysis of the epidemiological profile and the transmissibility variables of patients with HIV/Aids from the municipality of Imperatriz-MA.. Method: This is an observational cross-sectional study. Data collection was performed from the analysis of patients' records registered in the Center for Testing and Counseling (CTA) from 2017 to 2020. For data collection, a questionnaire with transmission variables and epidemiological characteristics of patients was used. Results: From January 2017 to December 2020, 211 medical records were filed. Of these, 71.6% were male, 55.5% of the participants were between 21 and 40 years, and 66.4% from Imperatriz-MA. The most prevalent type of exposure was sexual intercourse without a condom. Among the participants, 83.9% (n=177) were positive only for HIV. About 140 people with HIV had an undetectable viral load (VL) (< 50 copies/ml) after 6 months of using antiretroviral therapy, making it low transmissibility. Conclusion: The study was able to characterize the epidemiological profile of patients from the Specialized Assistance Service (SAE) in Imperatriz between 2017 and 2020. Despite the increase in the number of cases among women, the most affected public remains young men, from 21 to 40 years of age, with 8 to 11 years of education, single and brown. Sexual intercourse without a condom is the main type of exposure.(AU)

Conclusões: O estudo conseguiu caracterizar o perfil epidemiológico dos usuários de SAE em Imperatriz entre 2017 e 2020. Apesar do aumento no número de casos em mulheres, o público mais afetado continua sendo homens jovens, de 21 a 40 anos, com 8 a 11 anos de educação, solteiros e pardos. A relação sexual sem preservativo é o principal tipo de exposição.(AU)

Resistencia a los inhibidores de la integrasa en niños con el virus de la inmunodeficiencia humana por transmisión vertical: primeros casos en Uruguay / Resistance to integrase inhibitors in children with vertically-transmitted human immunodeficiency virus: First cases in Uruguay

La resistencia a los antirretrovirales (ARV) es un problema de salud pública. Con el uso de inhibidores de la integrasa (INSTI) en pediatría, también comienzan a aparecer resistencias. El objetivo de esta comunicación es describir 3 casos con resistencia a los INSTI. Se describen 3 pacientes pediátricos con transmisión vertical del virus de la inmunodeficiencia humana (VIH). Iniciaron ARV de lactantes y preescolares, con mala adherencia al tratamiento, cursaron con diferentes planes secundarios a comorbilidades asociadas y fallas virológicas por resistencia. Los 3 casos clínicos describen la rápida aparición de resistencia frente a la falla virológica y el compromiso de los INSTI. La adherencia debe ser supervisada para detectar precozmente el aumento de la viremia. La falla virológica en un paciente tratado con raltegravir obliga a un rápido cambio de esquema ARV, ya que continuar utilizándolo podría favorecer nuevas mutaciones y resistencia a los INSTI de segunda generación.

Antiretroviral (ARV) drug resistance is a public health issue. Resistance has also been observed in the case of integrase strand transfer inhibitors (INSTIs) used in pediatrics. The objective of this article is to describe 3 cases of INSTI resistance. These are the cases of 3 children with vertically-transmitted human immunodeficiency virus (HIV). They were started on ARVs as infants and preschoolers, with poor treatment adherence, and had different management plans due to associated comorbidities and virological failure due to resistance. In the 3 cases, resistance developed rapidly as a result of virological failure and INSTI involvement. Treatment adherence should be monitored so that any increase in viremia can be detected early. Virological failure in a patient treated with raltegravir forces to a rapid change in ARV therapy because its continued use may favor new mutations and resistance to second-generation INSTIs.

Consensus document of the Spanish Society of Paediatric Infectious Diseases and the Advisory Committee on Vaccines of the Spanish Association of Pediatrics for vaccination of immunosuppressed individuals.

The number of people with immunosuppression is increasing considerably due to their greater survival and the use of new immunosuppressive treatments for various chronic diseases. This is a heterogeneous group of patients in whom vaccination as a preventive measure is one of the basic pillars of their wellbeing, given their increased risk of contracting infections. This consensus, developed jointly by the Sociedad Española de Infectología Pediátrica (Spanish Society of Pediatric Infectious Diseases) and the Advisory Committee on Vaccines of the Asociación Española de Pediatría (Spanish Association of Paediatrics), provides guidelines for the development of a personalised vaccination schedule for patients in special situations, including general recommendations and specific recommendations for vaccination of bone marrow and solid organ transplant recipients, children with inborn errors of immunity, oncologic patients, patients with chronic or systemic diseases and immunosuppressed travellers.

Evolución temporal de la terapia antirretroviral (2017-2021): análisis de la modificación del tratamiento y su impacto económico / Temporal evolution of antiretroviral therapy (2017-2021): analysis of treatment change and its economic impact

Objetivos. Analizar las modificaciones de la terapia antirre troviral (TAR) y su impacto económico en la práctica clínica diaria. Material y métodos. Estudio observacional, retrospectivo de los pacientes que iniciaron TAR entre 01/2017-12/2021 (se guimiento hasta 12/2022). Variables recogidas: TAR, duración, motivo del cambio y costes del tratamiento. Resultados. 280 pacientes iniciaron TAR. La mediana de durabilidad de la 1ª línea fue: 19,9 meses en 2017 (IC95% 13,9-25,9), 12,2 meses en 2018 (IC95% 4,7-19,7), 27,4 meses en 2019 (IC95% 6,8-48,1) y no se alcanzó la mediana para los años 2020 y 2021 (p p<0,001). De un total de 541 líneas prescri tas, la triple terapia con inhibidores de la proteasa se modificó en el 63,8% (81/127), seguido de los inhibidores de la integrasa 52,1% (159/305), mientras que, la terapia dual (DTG/3TC) solo en el 8,3% (7/84). De un total de 261 modificaciones, la simpli ficación/optimización 47,5% (124/261) fue el principal motivo, seguido de efectos adversos 21,8% (57/261), siendo el 2017 el único año donde ambos motivos se encontraban al mismo nivel. El impacto económico de los cambios supusieron una re ducción del coste medio de 34,0€ [-391,4 a +431,4] al mes/ paciente. El año 2019 es el único año donde estos cambios se asociaron con un incremento del coste adicional medio (23,4€ [-358,3 a +431,4]). Conclusiones. Dejando atrás el fracaso virológico, la sim plificación a regímenes de un solo comprimido y de mayor tolerancia han marcado la nueva la era TAR. Con un impacto económico que, a pesar del punto de inflexión del 2019, refleja una reducción progresiva de costes mantenida en el tiempo (AU)

Objectives. To analyze the modifications of antiretrovi ral therapy (ART) and their economic impact on daily clinical practice. Material and methods. Observational, retrospective study of patients who started ART between 01/2017-12/2021 (follow-up until 12/2022). Variables collected: prescribed ART, duration, the reason for the change, and treatment costs. Results. A total of 280 patients initiated ART therapy. The median durability of 1st line was: 19.9 months in 2017 (95%CI 13.9-25.9), 12.2 months in 2018 (95%CI 4.7-19.7), 27.4 months in 2019 (95%CI 6.8-48.1) and the median was not reached for the years 2020 and 2021 (p<0.001). Triple therapy with protease inhibitors was changed in 63.8% (81/127) of cases, followed by integrase inhibitors 52.1% (159/305), while dual therapy (DTG/3TC) only in 8.3% (7/84). The main cause of dis continuation was simplification/optimization 47.5% (124/261), followed by adverse effects 21.8% (57/261), with 2017 being the only year where simplification/optimization was at the same level as adverse effects. The economic impact of ART changes resulted in an average cost reduction of 34.0€ [-391.4 to +431.4] per month per patient. The year 2019 stands out as the only year where these changes were associated with an increase in mean additional cost (23.4€ [-358.3 to +431.4]). Conclusions. Optimization/simplification accounts for almost half of the reasons for TAR change, with an econom ic impact that, despite the inflection point of 2019, each year manages to exceed the previous one, achieving a progressive cost reduction maintained over time (AU)

Infecciones orales por VPH en personas HIV positivas de Corrientes, Argentina / Oral HPV infection in HIV-positive persons from Cor rientes, Argentina

Resumen Introducción : Las infecciones por virus del papiloma humano (VPH) en cavidad oral se asocian a un subgrupo de cánceres cuya prevalencia está en incremento en todo el mundo. Las personas portadoras HIV (PHIV) tienen un mayor riesgo de contraer una infección por VPH y eventualmente desarrollar cáncer. El presente estudio trata de relevar la frecuencia y variabilidad genotípica de dicho virus en cavidad oral y su asociación con pro bables factores de riesgo en una población HIV+ de la provincia de Corrientes. Métodos : Se tomaron enjuagados bucales de 133 participantes. Luego de la extracción de ADN se detectó por PCR anidada la presencia de VPH. Los casos positivos se tipificaron por Reverse Line Blot y por secuenciación. Resultados : En la serie analizada se detectó una fre cuencia global de VPH del 22% (29/133) en los enjuagados bucales. El 62% (18/29) de los casos positivos presentó al menos un genotipo de alto riesgo. Los participantes con más de 36 años (p = 0.03, aOR = 3.2, IC = 1.1-9,4) y una carga viral de más de 40 copias/mL (p = 0.04, aOR = 3.3, IC = 1.1-10.3) reflejaron mayor riesgo de infección por VPH. La edad de inicio de relaciones sexuales también resultó un indicador útil en los casos que presenta ron infecciones por genotipos de alto riesgo (p = 0.04, aOR = 7.2, IC = 1.6-32.3). Además, se observaron genotipos de bajo riesgo no reportados con anterioridad en cavidad oral de habitantes de la región (VPH-13 y VPH-114). Discusión : Relevar datos epidemiológicos basales en pobla ciones vulnerables y altamente expuestas a VPH ayuda a clarificar la historia natural del virus en localizaciones extragenitales y a focalizarnos en particularidades regio nales que permitan elaborar políticas de salud acordes a la magnitud del problema local.

Abstract Introduction : Oral cavity HPV infections are associ ated with a subgroup of cancers whose prevalence is increasing worldwide. HIV infected people are in an increased risk of contracting HPV infection and devel oping cancer. The present study reveals the frequency and genotypic variability of this virus in the oral cavity and its association with probable risk factors in an HIV+ population of the province of Corrientes. Methods : Mouthwashes were taken from 133 partici pants. After DNA extraction, the presence of HPV was detected by nested PCR. Positive cases were typed by reverse line blot or by sequencing. Results : HPV was detected in 22% (29/133) of the mouthwashes. In 62% (18/29) of the positive samples, at least one high-risk genotype was detected. Participants older than 36 years (p = 0.03, aOR = 3.2, CI = 1.1-9.4) and a viral load of more than 40 copies (p = 0.04, aOR = 3.3, CI = 1.1-10.3) had higher risk of infection by any HPV genotype. In relation to the age of initiation of sexual intercourse, it was a significant parameter in the case of patients with infections by high-risk genotypes (p = 0.04, aOR = 7.2, IC = 1.6-32.3). In addition, previously unreport ed low-risk genotypes were observed in the oral cavity of inhabitants of the region like HPV-13 and HPV-114. Discussion : Collecting baseline epidemiological data in this type of vulnerable population helps to clarify the natural history of the virus in extragenital locations and focus on regional particularities that allow the development of health policies in accordance with the magnitude of the regional problem.

Se describe el caso clínico de un paciente infectado por el virus de la inmunodeficiencia humana en fase sintomática precoz, quien fue asistido en el Servicio de Dermatología del Hospital Clínico Quirúrgico Docente Dr. León Cuervo Rubio en Pinar del Río por presentar lesiones eritematosas infiltradas de tres meses de evolución en el miembro inferior derecho, con alteración de la sensibilidad térmica y dolorosa. Se le indicó baciloscopia y estudio histopatológico que confirmaron el diagnóstico de sospecha de lepra dimorfa tuberculoide, por lo que se comenzó a aplicar poliquimioterapia combinada con terapia antirretroviral, lo cual favoreció la evolución del paciente.

The case report of a patient infected by the human immunodeficiency virus in early symptomatic phase is described, who was seen at the Dermatology Service of the Dr. León Cuervo Rubio Teaching Clinical Surgical Hospital of Pinar del Río for presenting infiltrated erythematous lesions of three months of evolution in the right lower limb, with altered pain and thermal sensation. A basiloscopic and histopathologic study was indicated, which confirmed the presumptive diagnosis of borderline tuberculoid leprosy, and therefore polychemotherapy combined with antiretroviral therapy was started, which favored the patient's evolution.

Utilidad de la ecografía de la arteria femoral complementaria a la exploración carotídea para la detección de ateromatosis subclínica en pacientes con infección por el virus de la inmunodeficiencia humana / Usefulness of artery femoral ultrasound complementary to carotid exploration for the detection of subclinical atheromatosis in patients with human immunodeficiency virus infection

Introducción La detección de la enfermedad ateromatosa subclínica (EAS) en los pacientes con el virus de la inmunodeficiencia humana (VIH) se basa habitualmente en la ecografía carotídea. Sin embargo, estudios en otras enfermedades muestran una infraestimación de la EAS cuando se explora exclusivamente la región carotídea. Este estudio evalúa el impacto de la exploración combinada carotídea y femoral en la detección de la EAS. Métodos Estudio transversal y prospectivo de pacientes con VIH, diagnosticados entre 2008 y 2017. Se realizó ecografía carotídea y femoral. La EAS fue definida según los criterios de Mannheim. Resultados Se incluyeron 102 pacientes (edad media: 40 años, el 73,5% varones). La prevalencia de la EAS por exploración carotídea fue del 15,7% (n=16), y por exploración femoral fue del 18,6% (n=19). La proporción de pacientes con criterios de EAS global (afectación carotídea o femoral) fue del 23,5% (n=24) lo que implica un aumento absoluto de la detección de EAS del 7,84% (IC 95%: 2,63-13,06%). Conclusiones La detección de la EAS aumenta de forma importante con el uso combinado de la ecografía carotídea y femoral en la población con VIH. (AU)

Introduction Detection of subclinical atheromatosis disease (SAD) in patients with human immunodeficiency virus (HIV) infection is usually based on carotid ultrasound. However, studies in other pathologies have shown a probable underestimation of SAD when its detection is exclusively based on carotid exploration. This study evaluates the impact on detection of SAD in patients with HIV through combined carotid and femoral exploration. Methods Cross-sectional and prospective study of patients with HIV, diagnosed between 2008-2017. Carotid and femoral ultrasound examination was performed in all patients. EAS was defined according to Mannheim criteria. Results One hundred two patients were included (mean age: 40 years, 73.5% being male). The prevalence of carotid SAD in the total sample was 15.7% (n=16), and the prevalence of femoral SAD was 18.6% (n=19). The proportion of patients with global SAD criteria (carotid or femoral) was 23.5% (n=24), which implies an absolute increase in SAD detection of 7.84% (95% CI; 2.63-13.06%) at the total sample. Conclusions Detection of SAD is significantly increased by the combined use of carotid and femoral arterial ultrasound in the population affected by HIV infection. (AU)

Síndrome de linfocitosis infiltrativa difusa con neumonía intersticial en un paciente con VIH / Diffuse infiltrative lymphocytosis syndrome with interstitial pneumonia in a patient with HIV

El síndrome de linfocitosis infiltrativa difusa se produce en asociación con la infección por virus de la inmunodeficiencia humana; requiere cumplir con los criterios diagnósticos y descartar otras patologías infecciosas y autoinmunes. Se presenta el caso de una mujer de 47 años que consultó por edema parotídeo bilateral, síndrome sicca, tos y síndrome de impregnación. Se observó en la tomografía de tórax infiltrado en «vidrio esmerilado¼, parcheado y bilateral. Se realizó diagnóstico de virus de la inmunodeficiencia humana positivo y fibrobroncoscopia con lavado broncoalveolar sin desarrollo de patógenos. Se interpreta como neumonía intersticial linfoidea asociada a síndrome de linfocitosis infiltrativa difusa. Se inició terapia antirretroviral con buena evolución y desaparición de los síntomas y de los infiltrados pulmonares.

Diffuse infiltrative lymphocytosis syndrome occurs in association with HIV infection; it requires meeting the diagnostic criteria and ruling out other infectious and autoimmune pathologies. We present the case of a 47-year-old woman who consulted for bilateral parotid edema, sicca syndrome, cough and impregnation syndrome, which was observed in the chest tomography infiltrated in ground glass, patched and bilateral. A diagnosis of HIV positive and fiberoptic bronchoscopy with bronchoalveolar lavage was made without the development of pathogens. It is interpreted as lymphoid interstitial pneu monia associated with DILS. Antiretroviral therapy was started with good evolution and disappearance of symptoms and pulmonary infiltrates.

INTRODUCTION: Detection of subclinical atheromatosis disease (SAD) in patients with human immunodeficiency virus (HIV) infection is usually based on carotid ultrasound. However, studies in other pathologies have shown a probable underestimation of SAD when its detection is exclusively based on carotid exploration. This study evaluates the impact on detection of SAD in patients with HIV through combined carotid and femoral exploration. METHODS: Cross-sectional and prospective study of patients with HIV, diagnosed between 2008-2017. Carotid and femoral ultrasound examination was performed in all patients. EAS was defined according to Mannheim criteria. RESULTS: One hundred two patients were included (mean age: 40 years, 73.5% being male).

CONCLUSIONS: Detection of SAD is significantly increased by the combined use of carotid and femoral arterial ultrasound in the population affected by HIV infection.

Experiencia de un programa de profilaxis preexposición en una unidad de virus de la inmunodeficiencia humana hospitalaria. Descripción del perfil basal del usuario e identificación de oportunidades de mejora / PrEP program experience in a hospital HIV unit. Description of baseline user profile and identification of opportunities for improvement

Introducción: La profilaxis preexposición (PrEP) es una intervención biomédica dirigida a prevenir la infección por el VIH en personas seronegativas con alto riesgo de contraer la infección. Esta estrategia fue aprobada por el Ministerio de Salud de España en octubre de 2019. Objetivo: Presentar la experiencia inicial de la PrEP en la Unidad de VIH del Hospital Clínic de Barcelona, poniendo especial atención en el análisis de los factores de vulnerabilidad de la cohorte. Materiales y métodos: Estudio retrospectivo, descriptivo. Se analizan las características epidemiológicas, sociodemográficas y clínicas basales de los usuarios incluidos en el programa durante el primer año de funcionamiento, prestando particular atención a las infecciones, las prácticas de riesgo y el consumo de sustancias. Resultados: Se incluyeron 190 individuos, 177 hombres y 12 mujeres transexuales con una edad media de 35 años (8DE). El 70% tenía estudios superiores y la mitad nacionalidad española. Informaron de tener 10 parejas de media al trimestre y el 60% de practicar sexo anal desprotegido. El 31% presentó al menos una PCR positiva para ITS, siendo la N. gonorrhoeae el germen más prevalente (51%) y la muestra rectal la más afectada (21%). El 63% reportó el uso de chemsex, el 19% policonsumo y el 8% slamming. La mitad expresó su preocupación por el consumo y/o prácticas sexuales y un 25% la necesidad de ayuda. Conclusiones: El perfil del usuario de PrEP visitado en nuestra unidad hospitalaria justifica la creación de equipos multidisciplinares que permitan prestar una atención holística de la vida sexual de estas personas.(AU)

Introduction: Pre-Exposure Prophylaxis (PrEP) is a biomedical intervention to prevent HIV infection in seronegative people at high risk of becoming infected. This strategy was endorsed in October 2019 by the Spanish Ministry of Health. Objective: To present the PrEP initial experience in the HIV Unit of the Hospital Clínic of Barcelona, paying special attention to the analysis of the vulnerability factors in the cohort. Materials and methods: Retrospective, descriptive study. The epidemiological, sociodemographic, and clinical characteristics of the users included in the program during the first year are analyzed, paying particular attention to Infections, risky practices, and substance use. Results: 190 individuals were included, 177 men and 12 trans women with a mean age of 35 years (8 SD). 70% had higher education, and half had Spanish nationality. An average of 10 couples per trimester and 60% reported unprotected anal sex. 31% had at least one positive PCR for STIs, with N. gonorrhoeae being the most prevalent microorganism (51%) and the rectal sample the most affected (21%). 63% reported chemsex use, 19% polydrug use, and 8% “slamming”. Half expressed concern about consumption and/or sexual practices and 25% the need for help. Conclusions: The PrEP user profile attended in our Hospital Unit justifies the creation of multidisciplinary teams that allow us to provide holistic attention to the sexual life of these people.(AU)

Condições de vulnerabilidades de pessoas idosas vivendo com o Vírus da Imunodeficiência Humana (HIV) / Conditions of vulnerability of elderly people living with the Human Immunodeficiency Virus (HIV) / Condiciones de vulnerabilidades de personas ancianas que viven con el Virus de la Inmunodeficiencia Humana (HIV)

Estudo com objetivo de descrever as condições de vulnerabilidades de pessoas idosas ao Vírus da Imunodeficiência Humana (HIV). Trata-se de um estudo qualitativo e que utilizou como método a história oral temática, realizado no Serviço de Atendimento Especializado, com seis idosos com 65 anos ou mais. A coleta de dados se deu por uma entrevista em profundidade com questões sobre vulnerabilidades individuais, sociais e programáticas e os dados foram explorados por meio da análise de conteúdo temática. Entre as condições encontradas estão a ausência de preservativo nas relações sexuais; baixo grau de conhecimento e de procura por consultas e exames de rotina; presença do preconceito e discriminação; ruptura no convívio familiar; descoberta tardia do HIV e baixa capacitação da equipe de saúde. Enfrentar essas condições de vulnerabilidade pressupõe um debate sobre as políticas e normativas do cuidado às pessoas com HIV e a reconfiguração do modelo de cuidado focado na prevenção. (AU)

The aim of this study was to describe the conditions of vulnerability to HIV among older people. Using the thematic oral history method, we conducted a qualitative study in the SAE with six people aged 65 and over. The data were collected using in-depth interviews covering issues related to individual, social and programmatic vulnerabilities. The data were analyzed using content analysis. Vulnerability conditions included not using a condom, low level of knowledge of appointments and tests and health-seeking behavior; prejudice and discrimination; family break-ups; late diagnosis of HIV; and limited capacity of health teams. To tackle these vulnerability conditions, it is necessary to promote a debate about policies and regulations geared towards the care of people with HIV and reshape the prevention-based care model.

Hyperferritinemic sepsis secondary to invasive Toxoplasma gondii in a child with untreated HIV / Sepsis hiperferritinémica secundaria a Toxoplasma gondii invasiva en un paciente pediátrico con virus de inmunodeficiencia humana sin tratamiento

Abstract Background: Untreated human immunodeficiency virus (HIV)-immunosuppressed pediatric patients show high morbidity and mortality from opportunistic infections. Limited cases of hyperferritinemic sepsis have been described in patients with toxoplasmosis. Case report: We describe the case of a 13-year-old female patient with a history of untreated HIV who presented with hyperferritinemic sepsis secondary to Toxoplasma gondii infection and Pneumocystis jirovecci pneumonia. She received ventilatory support, inotropic drugs, treatment for opportunistic germs, and high-dose corticosteroids, but with unfavorable evolution. Conclusions: The global approach to sepsis with elevated ferritin guides to using of therapies aimed at neutralizing the severe inflammatory response. A timely diagnosis would allow prompt treatment and minimize complications.

Resumen Introducción: Los pacientes pediátricos inmunodeprimidos por el virus de la inmunodeficiencia humana (VIH) sin tratamiento presentan una elevada morbilidad y mortalidad por infecciones oportunistas. Se han descrito limitados casos de sepsis hiperferritinémica en pacientes con toxoplasmosis. Caso clínico: Se describe el caso de una paciente de 13 años con antecedente de VIH sin tratamiento que presentó sepsis hiperferritinémica secundaria a una infección por Toxoplasma gondii y neumonía por Pneumocystis jirovecci. Recibió soporte ventilatorio, uso de inotrópicos, tratamiento para gérmenes oportunistas y corticoides en altas dosis, pero su evolución fue desfavorable. Conclusiones: El abordaje global de la sepsis con ferritina elevada orienta a utilizar terapias dirigidas a neutralizar la respuesta inflamatoria severa, por lo que un diagnóstico oportuno permitiría iniciar el tratamiento prontamente y minimizar las complicaciones.
