[Translated article] Retrospective Study of Risk Markers for Developing High-Grade Anal Intraepithelial Neoplasm in Men Who Have Sex With Men Living With HIV.

BACKGROUND: High-grade anal intraepithelial squamous lesion is significantly prevalent among men who have sex with men and are infected with the human immunodeficiency virus (HIV). This condition-the precursor to anal cancer-significantly increases the risk of developing it. Conversely, low-grade anal intraepithelial squamous typically follow a benign course and usually regress spontaneously. MATERIALS AND METHODS: To describe a population of men who have sex with men living with HIV followed in a specialized anal cancer screening unit we conducted an observational, retrospective, and single-center study. RESULTS: Ninety-four patients were analyzed, with a mean age of 39±9 years, and a 87% positivity rate for high-risk human papillomavirus (HR-HPV). At the initial visit, 47% presented with low-grade squamous intraepithelial lesions. The progression rate to high-grade squamous intraepithelial lesion was 37.2 per 100,000 patients/year. None of the patients developed anal cancer. Tobacco and alcohol consumption were associated with this progression. DISCUSSION: In this series, longer duration of HIV infection, tobacco and alcohol use and the presence of HR-HPV were significantly associated with the occurrence of high-grade intraepithelial lesions. A lower risk of progression was seen in patients with higher education. CONCLUSION: In men who have sex with men living with HIV, the association of factors such as smoking, alcohol, the presence of HR-HPV and an increased burden of human papillomavirus disease makes these patients more susceptible to develop high-grade anal squamous lesions.

Routinely obtaining a sexual history is a necessary first step to identify which patients have specific sexual behaviours that may put them at risk and use appropriate protective measures, especially in vulnerable populations. However, late diagnosis of HIV infection remains very high. Combination prevention strategies based on condom promotion, harm reduction programs for people who inject drugs plus PrEP and HIV PEP are the best options to prevent new infections. Screening for STIs (including hepatotropic viruses) and early diagnosis and treatment are essential for the person since it improves the prognosis and complications and also for the community because it breaks the chain of transmission. People living with HIV who have an undetectable viral load do not transmit the virus sexually (undetectable=untransmittable).

Case report on activated PI3K-delta syndrome.

BACKGROUND: Activated phosphoinositide 3-kinase delta syndrome (APDS) [OMIM 615513] is an inborn error of immunity with autosomal dominant inheritance caused by a pathogenic variant in the PIK3CD gene. The prevalence ratio of APDS is < 1: 1,000,000 newborns. The main clinical features of APDS are sinopulmonary infections, benign lymphoproliferation, autoinflammatory disease, and a major risk of lymphoid neoplasms. CLINICAL CASE: A 17-year-old female with a history of pneumonia at 9 months of age subsequently developed recurrent respiratory tract infections, bronchiectasis, perforated otitis media, unilateral tonsillar lymphoid hyperplasia, pansinusitis, recurrent oral candidiasis, and chronic rhinitis. Laboratory studies reported persistent leukopenia and lymphopenia, low CD4 lymphocyte subpopulation, and persistently elevated immunoglobulin M immunoglobulin studies with values up to 692 mg/dL. An inborn error of immunity next-generation sequencing and multiplex ligation-dependent probe amplification analysis detected a heterozygous pathogenic variant in the PIK3CD gene, compatible with APDS. Treatment with monthly injectable gamma globulin and prophylactic antibiotics was started, allowing better control of the infectious processes. CONCLUSION: This is the second case of APDS reported in Mexico in the literature. It is important to be aware of this condition to make a timely diagnosis, which requires a high clinical suspicion and immunological and genetic studies to provide adequate treatment and prevent complications.

INTRODUCCIÓN: El síndrome de la Fosfoinositida 3-cinasa delta activado (Activated Phosphoinositide 3-kinase δ síndrome, APDS) [OMIM 615513] es un error innato de la inmunidad con patrón de herencia autosómica dominante causada por una variante patogénica heterocigota del gen PIK3CD. Su prevalencia es < 1: 1,000,000 nacidos vivos. Las principales manifestaciones clínicas son infecciones sinopulmonares, linfoproliferación benigna, autoinmunidad y aumento del riesgo de malignización linfoide. CASO CLÍNICO: Femenino de 17 años de vida con antecedentes de neumonía a los 9 meses de edad, posteriormente infecciones de vías respiratorias recurrentes, bronquiectasias, otitis media perforada, hiperplasia linfoide de amigdala unilateral, pansinusitis, candidiasis oral recurrente y rinitis crónica. Los estudios de laboratorio reportaron leuco linfopenia persistente, subpoblación linfocitaria con CD4 baja y estudios de inmunoglobulinas con IgM persistentemente elevada con valor de hasta 692 mg/dl. Se realizó estudio molecular de secuenciación de siguiente generación (NGS por sus siglas en inglés Next-Generation Sequencing) y amplificación de sondas dependientes de ligandos múltiples (MLPA por sus siglas en inglés Multiplex Ligation-dependent Probe Amplification) dirigido a errores innatos de la inmunidad que detectó una variante patogénica en estado heterocigoto en el gen PIK3CD, compatible con APDS. Se inició tratamiento con gammaglobulina intravenosa mensual y antibiótico profiláctico, permitiendo mejor control de los procesos infecciosos. CONCLUSIONES: Este es el segundo caso reportado en la literatura de APDS en México, por lo que es importante su conocimiento para poder realizar un diagnóstico oportuno, para el cual se requiere una alta sospecha clínica, además de estudios inmunológicos y genéticos, con la finalidad de otorgar el tratamiento adecuado y prevenir complicaciones.

Autoimmunity in patients with inborn errors of immunity: A case series.

OBJECTIVE: To assess the prevalence of systemic and organ-specific autoimmunity among individuals with human inborn errors of immunity (IEI). METHODS: Retrospective study. We recorded demographic variables, type of immunodeficiency, and systemic and organ specific autoimmunity. RESULTS: We included 48 patients (54.1% men) with mean age of 32.1 years. The most common IEIs included combined immunodeficiency with syndromic features (31.2%) and predominantly antibody deficiency (20.1%). We observed autoimmunity in 15 patients (31.2%): 12 organ-specific autoimmunity and 5 systemic autoimmunity, not mutually exclusive groups. Organ-specific autoimmunity preceded the onset of IEI in 5 patients, was concurrent in one patient, and developed after the diagnosis of IEI in 6 cases. From the systemic autoimmunity group, we observed polyarteritis nodosa (n = 2), antiphospholipid syndrome (APS) (n = 2), and overlap of limited systemic sclerosis/APS/Sjögren's syndrome (n = 1), and in all cases, this occurred after the IEI diagnosis. CONCLUSION: Our findings confirm the coexistence of autoimmunity and IEI. This overlap may be attributed to B and T cell disorders, as well as potential alterations in the microbiota in these patients.

Qualidade do acesso percebida por usuários de serviços especializados em HIV/AIDS da Bahia, Brasil / Quality of access perceived by users of HIV/AIDS specialized services in Bahia, Brazil / Calidad de acceso percibida por los usuarios de servicios especializados en VIH/SIDA en Bahía, Brasil

Este artigo descreve o acesso e a percepção do acesso de usuários a serviços especializados no tratamento do vírus da imunodeficiência humana e da Síndrome da Imunodeficiência Humana (HIV/AIDS) em municípios baianos por meio de um recorte epidemiológico descritivo-analítico, com abordagem quantitativa de dados primários de estudo realizado em cinco serviços localizados na capital e oito no interior do estado da Bahia, Brasil. Participaram deste estudo 475 usuários, de 21 municípios baianos, predominantemente do sexo feminino, com faixa etária entre 25 e 44 anos, negros, cristãos, desempregados, com escolaridade compreendendo o ensino fundamental, renda de até três salários mínimos, heterossexual e cisgênero. O acesso à testagem para HIV e outras Infecções Sexualmente Transmissíveis (IST), profilaxias de pós-exposição e pré-exposição e outros insumos de prevenção não constituíram motivação de inserção no serviço. O tratamento específico e a assistência médica para HIV e outras IST foi motivação para que a maioria dos participantes se direcionassem ao serviço especializado. O deslocamento até o serviço de referência é realizado principalmente por transportes coletivos, e o trajeto casa-serviço tem duração de pelo menos uma hora. O horário de funcionamento da unidade atende às necessidades da maior parte dos participantes, mas parcela dos usuários mencionaram o desejo de funcionamento em horários alternativos. A marcação de consultas é realizada principalmente de forma presencial e por telefone, com possibilidade de agendamento diário, assim a maioria dos usuários avaliaram a organização do serviço para marcação de consultas como boa ou muito boa. O tempo de espera, entre marcação e consulta, mais comum é de uma semana a um mês.

This article describes user access and perception of access to specialized HIV/AIDS services in Bahia municipalities by applying a qualitative epidemiological, descriptive-analytical approach to primary data from research conducted in five services located in the capital and eight in the countryside. A total of 475 users from 21 municipalities in Bahia participated in this study. Most were female, between 25 and 44 years old, Black, Christian, unemployed, with complete primary education, income of up to 3 minimum wages, heterosexual and cisgender. Access to HIV testing and other STIs, post-exposure and pre-exposure prophylaxis and other prevention inputs did not constitute motivation for procuring the service. Specific treatment and medical care for HIV and other STIs motivated most participants to turn to specialized services. Commuting to the reference service is made mainly by public transport and the home-service journey takes at least one hour. The unit's opening hours meet the needs of most participants, but some mentioned the desire for alternative operating times. Appointments are booked mainly in person and over the phone, with the possibility of daily scheduling, so most users rated the service organization for scheduling appointments as good or very good. The most common waiting time between booking and consultation is one week to one month.

Neumonía atípica por Lophomonas blattarum en un paciente inmunocomprometido: reporte de un caso / Atypical pneumonia due to Lophomonas blattarum in an immunocompromised patient: case report

Resumen La infección respiratoria por Lophomonas blattarum es una patología oportunista poco frecuente, sin embargo, las personas inmunodeprimidas son susceptibles a contraer esta infección. A continuación, se presenta un caso de neumonía por Lophomonas blattarum en un paciente de 44 años de edad con Virus de Inmunodeficiencia Humana (VIH), quien ingresó al Hospital Militar Regional de Puebla con cuadro de dificultad respiratoria, tos no productiva, dolor torácico y fiebre; durante su abordaje inicial se detecta una prueba de anticuerpos VIH 1-2 con resultado presuntivo positivo. Los estudios de imagen muestran hallazgos característicos de neumonía por microorganismos atípicos por lo que se decide tratamiento empírico a base de cefalosporina, macrólido, triazoles y sulfonamida. El cultivo de secreción bronquial reveló un parásito protozoo multiflagelado (L. blattarum), por lo que se inició manejo farmacológico con metronidazol con una dosis de impregnación de 1500 miligramos, continuando con 500 miligramos cada 8 horas por 2 semanas, con lo que se logró mejoría de los síntomas y función respiratoria. Concluye su estancia en el Hospital Regional de Puebla, para seguimiento y confirmación de VIH en tercer nivel de atención. Finalmente, a pesar del tratamiento antibiótico, los pacientes inmunodeprimidos aunado a cualquier infección oportunista, la mortalidad está presente en más de un 80 %.

Abstract Respiratory infection by Lophomonas blattarum is a rare opportunistic pathology, however, immunocompromised individuals are susceptible to contract this infection. The following is a case of Lophomonas blattarum pneumonia in a 44-year-old patient with Human Immunodeficiency Virus (HIV), who was admitted to the Regional Military Hospital of Puebla with respiratory distress, non-productive cough, chest pain and fever; during his initial approach a presumptive positive HIV 1-2 Ac. test was detected. Imaging studies showed findings characteristic of pneumonia caused by atypical microorganisms, so empirical treatment with cephalosporin, macrolide, triazoles and sulfonamide was decided. The bronchial secretion culture revealed a multiflagellate protozoan parasite (L. blattarum), so pharmacological management was started with metronidazole with an impregnation dose of 1500 milligrams, continuing with 500 milligrams every 8 hours for 2 weeks, which resulted in improvement of symptoms and respiratory function. She concluded her stay at the Regional Hospital of Puebla, for follow-up and confirmation of HIV at the third level of care. Finally, despite antibiotic treatment, immunosuppressed patients, together with any opportunistic infection, mortality is present in more than 80%.

Antibody persistence 7 years after hepatitis-A vaccine in children with human immunodeficiency virus infection / Persistencia de anticuerpos siete años después de la vacuna de la hepatitis A en niños con infección por el virus de la inmunodeficiencia humana

Abstract 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.

Resumen 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.

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.

Neoplasia endócrina múltiple y enfermedad inflamatoria intestinal de inicio muy temprano. Una asociación inesperada / Multiple endocrine neoplasia and very early onset in flammatory bowel disease. An unexpected association

Resumen La enfermedad inflamatoria intestinal de inicio muy temprano (VEOIBD) es una entidad rara en pediatría. Es conocida su asociación con inmunodeficiencias prima rias de origen monogénico. Presentamos el caso de una paciente con diagnóstico de VEOIBD a quien se le realizó una secuenciación masiva del exoma. El resultado del estudio permitió identificar una variante patogénica en el proto oncogen RET, asociada con enfermedad neoplasia endocrina múltiple tipo 2A. No hay reportes de asociación de variantes en el proto oncogen RET con VEOIBD. No se puede adjudicar la presencia de estas dos entidades clínicas a una única causa genética.

Abstract Very early onset inflammatory bowel disease (VEOI BD) is a rare entity in pediatrics. Its association with pri mary immunodeficiencies of monogenic origin is known. We present the case of a patient diagnosed with VEOIBD who underwent massive paralleled exome sequencing. The result of the study showed a pathogenic variant in the RET proto-oncogene, associated with multiple endo crine neoplasia type 2A disease. There are no previous reports of association of RET proto-oncogene variants with VEOIBD. The presence of these two clinical entities cannot be attributed to a single genetic cause.

Características clínicas y respuesta al tratamiento del linfoma en personas que viven con el virus de la inmunodeficiencia humana (VIH) en un centro de referencia de Latinoamérica / Clinical characteristics and response to lymphoma treatment in people living with the human immunodeficiency virus (HIV) in a reference center in Latin America

Resumen Introducción. Los linfomas son neoplasias malignas caracterizadas por la proliferación clonal de linfocitos. Las personas portadoras del virus de inmunodeficiencia humana (VIH) desarrollan los subtipos más agresivos de linfoma. En México se conoce poco acerca de las características clínicas y la respuesta al tratamiento del linfoma en las personas que viven con el VIH. Material y métodos. Un estudio descriptivo, retrospectivo y transversal fue realizado en un hospital de referencia en el estado de Veracruz, México, la tercera entidad federativa mexicana con mayor número de casos de VIH. Pacientes ≥18 años, portadores del VIH y diagnosticados con linfoma no Hodgkin o Hodgkin entre junio 2017 a junio 2022 fueron incluidos en el estudio. Además del análisis descriptivo, se calcularon las curvas de KaplanMeier para la sobrevida y las hazard ratio (HR) mediante regresión de Cox para determinar el riesgo de muerte asociada a los diferentes factores. Resultados. Se analizó una cohorte de 32 personas que viven con el VIH con linfoma no Hodgkin (n= 30) o linfoma de Hodgkin (n= 2). El 90% del total de los pacientes fueron del sexo masculino con una mediana de edad de 39.3 años (25-68). El 40% de los pacientes presentó el linfoma y VIH al mismo tiempo, el 60% restante desarrollaron el linfoma en un período entre 1 y 22 años, con una media de tiempo de 6.8 años, de los cuales el 79% recibió terapia antirretroviral y registraba carga viral indetectable. El linfoma más frecuente fue el linfoma difuso de células grandes B (37.5%). La media de supervivencia global de los pacientes fue 6.65 años, con intervalos de confianza (IC) del 95% de 3.93 a 9.37 años con error estándar de 1.38 años; la probabilidad acumulada de supervivencia fue 0.4, con un error estándar de 0.1. En la regresión de Cox la albúmina ≤ 3 g/ dL tuvo un alto cociente de riesgo (HR= 5.69; IC 95%: 1.38-23.45, p= 0.016) para mortalidad, donde los pacientes con estos niveles de albúmina tuvieron una media de sobrevida de 9.8 meses. Discusión. A pesar de que los linfomas asociados a VIH son agresivos y se presentan en estadios avanzados, la sobrevida global alcanzada en este estudio fue similar a estudios previos. El esquema R-CHOP mostró buena respuesta en el LDCGB, pero continúa siendo controvertido el manejo de los otros tipos de linfoma. La hipoalbuminemia fue un factor de riesgo para mortalidad, por lo que podría incluirse en nuevas escalas pronósticas.

Abstract Introduction. Lymphomas are malignant neoplasms characterized by clonal proliferation of lymphocytes. Persons carrying the human immunodeficiency virus (HIV) develop the most aggressive subtypes of lymphoma. In Mexico, little is known about the clinical characteristics and response to treatment of lymphoma in people living with HIV. Material and methods. A descriptive, retrospective, cross-sectional study was conducted at a referral hospital in the state of Veracruz, Mexico, the third Mexican federative entity with the highest number of HIV cases. Patients ≥18 years old, HIV carriers and diagnosed with non-Hodgkin's or Hodgkin's lymphoma between June 2017 to June 2022 were included in the study. In addition to the descriptive analysis, Kaplan-Meier curves for survival and hazard ratio (HR) by Cox regression were calculated to determine the risk of mortality associated with the different factors. Results. A cohort of 32 people living with HIV with non-Hodgkin's lymphoma (n= 30) or Hodgkin's lymphoma (n= 2) was analyzed. Ninety percent of the total patients were male with a median age of 39.3 (25-68). The remaining 60% developed lymphoma in a period between 1 and 22 years, with a mean time of 6.8 years, of which 79% received antiretroviral therapy and had an undetectable viral load. The most frequent lymphoma was diffuse large B-cell lymphoma (37.5%). The mean overall survival of the patients was 6.65 years, with a 95% confidence interval (CI) of 3.93 to 9.37 years and standard error of 1.38 years; the cumulative probability of survival was 0.4, with a standard error of 0.1. In Cox regression albumin ≤ 3 g/dL had a high hazard ratio (HR= 5.69; 95% CI: 1.38-23.45, p= 0.016) for mortality, where patients with these albumin levels had a mean survival of 9.8 months. Discussion. Despite the fact that HIV-associated lymphomas are aggressive and present in advanced stages, the overall survival achieved in our unit is similar to that reported in the world literature. The R-CHOP scheme has a good response in DLBCL, but the management of other types of lymphoma remains controversial. Hypoalbuminemia was found to be the most important predictor of mortality, so it could be included in new prognostic scales.

Prescrição de profilaxia pós exposição ao vírus da imunodeficiência humana por enfermeiros / Prescription of post exposure prophylaxis to the human immunodeficiency virus by nurses / Prescripción de profilaxis post exposición al virus de la inmunodeficiencia humana por enfermeros

Objetivo: Analisar e comparar as prescrições de profilaxia pós exposição ao HIV por enfermeiros e médicos nos serviços públicos de saúde de Florianópolis. Métodos: Estudo descritivo exploratório retrospectivo de abordagem quantitativa, que visou identificar as prescrições de profilaxia pós exposição ao vírus do HIV consoante com os dados dos relatórios do Sistema de Controle Logístico de Medicamentos e sistema de prontuário eletrônico CELK Saúde no período de maio de 2020 a maio de 2022. Resultados: A pesquisa demonstrou que houve 2899 prescrições de PEP no município, sendo 540 realizadas por enfermeiros e 1315 por médicos e demais prescrições desconsideradas da pesquisa devido inconsistências. Conclusão: Os números da pesquisa sinalizaram um quantitativo de prescrições de enfermagem inferior ao dos profissionais médicos. Apesar das prescrições em número reduzido quando comparado aos médicos, o profissional de enfermagem tem um papel de destaque no aumento da adesão aos tratamentos de saúde, diagnósticos precoces e redução de soroconversões. Por essa razão, faz-se crucial o fomento da autonomia prescritiva nessa profissão, dado a importância dos enfermeiros no aumento do acesso à saúde. (AU)

Objective: To analyze and compare prophylaxis prescriptions after exposure to the human immunodeficiency virus by nurses and doctors in public health services in Florianópolis. Methods: Retrospective exploratory descriptive study with a quantitative approach, which aimed to identify prophylaxis prescriptions after exposure to the HIV virus according to data from reports from the Medication Logistics Control System and the CELK Saúde electronic medical record system from May 2020 to May 2022. Results: The research demonstrated that there were 2899 PEP prescriptions in the municipality, 540 of which were carried out by nurses and 1315 by doctors and other prescriptions were disregarded from the research due to inconsistencies. Conclusion: The research numbers indicated a lower number of nursing prescriptions than that of medical professionals. Despite prescriptions being reduced in number when compared to doctors, nursing professionals play a prominent role in increasing adherence to health treatments, early diagnoses and reducing seroconversions. For this reason, it is crucial to promote prescriptive autonomy in this profession, given the importance of nurses in increasing access to healthcare. (AU)

Objetivo: Analizar y comparar las prescripciones de profilaxis después de la exposición al virus de la inmunodeficiencia humana por parte de enfermeros y médicos en servicios públicos de salud de Florianópolis. Métodos: Estudio descriptivo exploratorio retrospectivo, con enfoque cuantitativo, que tuvo como objetivo identificar prescripciones de profilaxis después de la exposición al virus VIH según datos de los informes del Sistema de Control Logístico de Medicamentos y del sistema de historia clínica electrónica CELK Saúde de mayo de 2020 a mayo de 2022. Resultados: La investigación mostró que hubo 2.899 prescripciones de PEP en el municipio, de las cuales 540 fueron realizadas por enfermeros y 1.315 por médicos y otras prescripciones fueron descartadas de la investigación por inconsistencias. Conclusión: Los números de la encuesta indicaron un número menor de prescripciones de enfermería que de los profesionales médicos. Aunque las prescripciones son reducidas en número en comparación con las de los médicos, los profesionales de enfermería desempeñan un papel destacado en el aumento de la adherencia a los tratamientos de salud, el diagnóstico precoz y la reducción de las seroconversiones. Por este motivo, es crucial promover la autonomía prescriptiva en esta profesión, dada la importancia de las enfermeras para aumentar el acceso a la atención sanitaria. (AU)

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)

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.
