Cognitive impairment among older adults with HIV: a systematic review protocol of cohort studies / Transtornos cognitivos em idosos vivendo com HIV: protocolo de revisão sistemática com estudos de coorte

OBJECTIVES: This review will determine whether the incidence of cognitive impairment in HIV patients aged ≥ 50 years is greater than that of their HIV-negative peers. METHODS: The MEDLINE, EMBASE, LILACS, Web of Science, and Scopus databases will be searched for studies with a sample of individuals aged ≥ 50 years or a mixed population with ≥ 50% aged ≥ 50 years). It will include studies that evaluate seropositive patients compared to and an unexposed control group. STUDY DESIGN: Cohort studies with follow-up ≥ 24 months will be included. Three reviewers will independently screen for eligibility criteria, extract data, and assess the risk of bias in the included studies, as well as evaluate the overall quality of evidence. A narrative synthesis will be prepared according to synthesis without meta-analysis guidelines. EXPECTED RESULTS: We expect to find correlations between older age, HIV, and cognitive impairment. RELEVANCE: The association of geriatric syndromes and HIV is becoming an important field of study. Increased life expectancy accompanied by an active sex life is contributing to this public health problem. This protocol is reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols and is registered in PROSPERO (CRD42022321914). This study was financed in part by the CAPES foundation (financial code: 001)

OBJETIVOS: Esta revisão abordará o questionamento: a incidência de comprometimento cognitivo é maior em pacientes com 50 anos ou mais com o vírus da imunodeficiência humana do que em idosos soronegativos? METODOLOGIA: As bases de dados Medical Literature Analysis and Retrieval System Online (MEDLINE), EMBASE, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Web of Science e Scopus serão pesquisadas. A estratégia de busca considerará estudos com amostra de 50 anos ou mais e população mista (pelo menos 50% com 50 anos ou mais). Incluirá estudos que avaliam pacientes soropositivos, e o controle considerará pesquisas que abordem pessoas não expostas. DESENHO DO ESTUDO: Serão incluídos estudos de coorte com seguimento de pelo menos 24 meses. Três revisores, de forma independente, farão a triagem dos artigos quanto aos critérios de elegibilidade, extrairão dados, avaliarão o risco de viés dos trabalhos e avaliarão a qualidade geral das evidências.

Neurochagas: atualização clínica / Neurochagas: clinical update

A doença de Chagas ainda é uma doença tropical muito prevalente no Brasil. Pode apresentar duas fases (aguda e crônica) e exibe grandes repercussões, sobretudo as que envolvem o sistema nervoso periférico e/ou central. Com o aumento do número de pessoas vivendo em estado (transitório ou permanente) de imunossupressão, os casos de manifestações neurológicas por neurochagas aumentaram, e este tornou-se um importante diagnóstico diferencial com outras doenças oportunistas. Este artigo teve como objetivo revisar os principais aspectos clínicos e terapêuticos da doença de Chagas no sistema nervoso central.

Chagas disease is still a very prevalent tropical disease in Brazil. It can have two phases - acute and chronic ­ and shows major repercussions, especially those involving the peripheral and/ or central nervous system. With the increase in the number of people living in the (transient or permanent) state of immunosuppression the cases of neurological manifestations of Chagas disease increased and this became an important differential diagnosis with other opportunistic diseases. This article aimed to review the main clinical and therapeutic aspects of central nervous system Chagas disease

Estudio comparativo de los resultados del tratamiento del carcinoma anal escamoso en los pacientes HIV positivos y negativos / Comparative study of the results of the treatment of squamous anal carcinoma in HIV positive and negative patients

Introducción: El tratamiento del carcinoma anal escamoso (CAE) en los pacientes HIV positivos resulta controvertido. Si bien las guías actuales recomiendan realizar en los pacientes con buen estado inmunológico la quimiorradioterapia (QRT) concurrente estándar, algunos autores consideran que estos pacientes presentan mayor toxicidad y peores resultados a largo plazo, por lo que requerirían un abordaje diferente. El objetivo de este trabajo es comparar los resultados del tratamiento del CAE en los pacientes VIH positivos y negativos. Diseño: Estudio retrospectivo comparativo. Pacientes y métodos: Se revisaron retrospectivamente las historias clínicas de los pacientes tratados en el Sector Coloproctología, Hospital Fernández, entre 01/2007 y 10/2018. Los del conducto anal se dividieron en: Grupo I: VIH negativos y Grupo II: VIH positivos. Se compararon variables demográficas, factores de riesgo específicos, estadificación, QRT (drogas, toxicidad y respuesta), tratamiento quirúrgico curativo/paliativo, persistencia/recurrencia y supervivencia específica y global. Resultados: Se incluyeron 28 pacientes (18 mujeres); margen: 2, conducto: 26 (Grupo I: 15. Grupo II: 11). Los VIH positivos eran en su mayoría hombres que tienen sexo con hombres vs. 100% de mujeres VIH negativas (p<0,01), más jóvenes (45,2±0,9 vs. 63,6±8; p<0,01) y tabaquistas (82% vs. 27%; p=0,005). No hubo diferencia significativa en la estadificación, aunque el Grupo II tuvo tumores con complicaciones más severas. Pudieron completar el tratamiento: Grupo I: 93%, Grupo II: 64% (p<0,05). Tuvieron respuesta completa a la QRT 13/14 (93%) pacientes del Grupo I y 3/7 (43%) del Grupo II (p<0,01). Hubo 3 recurrencias, 2 locorregionales y 1 a distancia (p=NS). Los VIH positivos requirieron más cirugías (82% vs. 27%; p<0,01). A 5 pacientes (4 del Grupo II) se les realizó una resección abdominoperineal (RAP). Tuvieron colostomía definitiva, con o sin RAP, el 46% de los pacientes, la mayoría VIH positivos (82% vs. 27%; p=0,002). En los VIH positivos el RR de mortalidad por cáncer fue 4 (IC95%: 1,01-16,5; p=0,02) y el RR de mortalidad global fue 5,45 (IC95%: 1,42-20,8; p=0,002). Tuvieron menor supervivencia, tanto global (p=0,001) como libre de enfermedad (p=0,01). Mediana de seguimiento: 27 meses (4-216).Conclusiones: Los pacientes VIH positivos con CAE se diferenciaron de los VIH negativos en una menor tasa de respuesta completa a la QRT y una mayor necesidad de tratamiento quirúrgico. Además, tuvieron una supervivencia global y libre de enfermedad significativamente menor que los VIH negativos. (AU)

INTRODUCTION: The treatment of anal squamous cell carcinoma (SCC) in HIV-positive patients is controversial. Although current guidelines recommend performing standard concurrent chemoradiotherapy (CRT) in patients with good immune status, some authors believe that these patients have greater toxicity and worse long-term results, so they would require a different approach. The purpose of this study was to compare the results of SCC treatment in HIV-positive and HIV-negative patients.DESIGN: Comparative retrospective study.PATIENTS AND METHODS: The records of patients treated in the Coloproctology Section, Hospital Fernández, between 01/2007 and 10/2018 were retrospectively reviewed. Those of the anal canal were divided into: Group I: HIV-negative and Group II: HIV-positive. Demographic variables, specific risk factors, staging, CRT (drugs, toxicity, and response), curative/palliative surgical treatment, persistence/recurrence, and cancer-specific and global survival were compared.RESULTS: 28 patients (18 women), margin: 2, conduit: 26 (Group I: 15. Group II: 11). The HIV-positive were mostly men who have sex with men (vs. 100% HIV-negative women; p<0.01), younger (45.2 ± 0.9 vs. 63.6 ± 8; p<0.01) and smokers (82% vs. 27%; p=0.005). There was no significant difference in staging, although Group II had tumors with more severe complications. Completed the treatment: Group I: 93%, Group II: 64% of patients (p<0,05). Thirteen out of 14 (93%) patients in Group I, and 3/7 (43%) patients in Group II had a complete response to CRT (p<0.01). There were 3 recurrences, 2 loco-regional and 1 distance (p=NS). HIV-positive required more surgery (82% vs. 27%; p<0.01). 5 patients (4 of Group II) underwent an abdominal-perineal resection (APR). Forty six percent of patients had permanent colostomy, with or without APR, most of them were HIV-positive (82% vs. 27%; p=0.002). In HIV-positive patients, the RR of cancer mortality was 4 (95% CI: 1.01-16.5; p=0.02) and the RR of overall mortality was 5.45 (95% CI: 1.42-20, 8; p=0.002). They also had lower overall (p=0.001) and disease-free survival (p=0.01). Median follow-up: 27 months (4 - 216).CONCLUSION: HIV-positive patients with anal SCC were different from HIV-negative patients in that they had a lower complete response rate to CRT, and a greater need for surgical treatment. They had a significantly lower overall and disease-free survival than HIV-negative patients. (AU)

TB-HIV co-infection: spatial and temporal distribution in the largest Brazilian metropolis / Coinfecção TB-HIV: distribuição espacial e temporal na maior metrópole brasileira

ABSTRACT OBJECTIVE To describe the spatial and temporal distribution of TB-HIV co-infection, as well as the profile of the characteristics of the co-infected population in the municipality of São Paulo. METHODS This is an ecological and time series study with data from the Tuberculosis Patient Control System (TBWeb), including all new cases of tuberculosis co-infected individuals with HIV living in the municipality from 2007 to 2015. Time trends of the disease were analyzed using Prais-Winsten regression. The cases were geocoded by the address of residence for the elaboration of maps with the incidence rates smoothed by the local empirical Bayesian method. The global and local Moran indexes evaluated spatial autocorrelation. Individuals' profiles were described and the characteristics of the cases with and without fixed residence were compared by Pearson's chi-square or Fisher's exact tests. RESULTS We analyzed 6,092 new cases of TB-HIV co-infection (5,609 with fixed residence and 483 without fixed residence). The proportion of TB-HIV co-infection ranged from 10.5% to 13.7%, with a drop of 3.0% per year (95%CI -3.4 - -2.6) and was higher in individuals without fixed residence. Incidence rates decreased by 3.6% per year (95%CI -4.4% - -2.7%), declining from 7.0 to 5.3 per 100,000 inhabitants/year. Co-infection showed positive and significant spatial autocorrelation, with heterogeneous spatial pattern and a high-risk cluster in the central region of the municipality. Cure was achieved in 55.5% of cases with fixed residence and in 32.7% of those without a fixed residence. CONCLUSIONS The data indicate an important advance in the control of TB-HIV co-infection in the period analyzed. However, we identified areas and populations that were unequally affected by the disease and that should be prioritized in the improvement of actions to prevent and control co-infection.

RESUMO OBJETIVO Descrever a distribuição espacial e temporal da coinfecção TB-HIV, assim como o perfil das características da população coinfectada no município de São Paulo. MÉTODOS Estudo ecológico e de série temporal com dados do Sistema de Controle de Pacientes com Tuberculose (TBWeb), incluindo todos os casos novos de tuberculose coinfectados pelo HIV residentes no município no período de 2007 a 2015. Tendências temporais do agravo foram analisadas por regressão de Prais-Winsten. Os casos foram geocodificados pelo endereço de residência para a elaboração de mapas com as taxas de incidência suavizadas pelo método bayesiano empírico local. Os índices de Moran global e local avaliaram a autocorrelação espacial. O perfil dos indivíduos foi descrito e as características dos casos com e sem residência fixa foram comparadas pelos testes de qui-quadrado ou exato de Fisher. RESULTADOS Foram analisados 6.092 casos novos de coinfecção TB-HIV (5.609 com residência fixa e 483 sem residência fixa). A proporção de coinfecção TB-HIV variou de 10,5% a 13,7%, com queda de 3,0% ao ano (IC95% -3,4 - -2,6), e foi maior nos indivíduos sem residência fixa em todo o período. As taxas de incidência apresentaram diminuição de 3,6% ao ano (IC95% -4,4% - -2,7%), declinando de 7,0 para 5,3 por 100 mil habitantes/ano. A coinfecção apresentou autocorrelação espacial positiva e significativa, com padrão espacial heterogêneo e um aglomerado de alto risco na região central do município. A cura foi alcançada em 55,5% dos casos com residência fixa e em 32,7% daqueles sem residência. CONCLUSÕES Os dados indicam um importante avanço no controle da coinfecção TB-HIV no período analisado. Todavia, foram identificadas áreas e populações que se apresentaram desigualmente afetadas pelo agravo, e que devem ser priorizadas no aprimoramento das ações de prevenção e controle da coinfecção.

Vulnerability factors associated with HIV/AIDS hospitalizations: a case-control study / Factores de vulnerabilidad asociados a la hospitalización del VIH/SIDA: estudio de control de casos / Fatores de vulnerabilidade associados às internações por HIV/aids: estudo caso controle

ABSTRACT Objectives: to identify the association between HIV/AIDS hospitalizations and factors that integrate individual, social, and programmatic vulnerabilities. Methods: a case-control study conducted in 2014 in a municipality in the state of São Paulo. "Cases" included people living with HIV (PLHIV) hospitalized and "control" those who were outpatients. Interviews were conducted using a tool with sociodemographic variables, clinical characteristics and other vulnerabilities. Data were analyzed by conditional logistic regression. Results: fifty-six cases and 112 control participated. Risk factors for HIV hospitalization were: unemployed and retired individuals; homeless people; non-antiretroviral users; individuals who did not regularly attend returns. Access to social workers was a protective factor for hospitalization. Conclusions: this research contributed to measure the social, individual and programmatic vulnerabilities that interfere with HIV worsening and, consequently, unfavorable outcome such as hospitalization.

RESUMEN Objetivos: identificar la asociación entre las hospitalizaciones por VIH/SIDA y los factores que integran las vulnerabilidades individuales, sociales y del programa. Métodos: estudio de casos y controles realizado en 2014 en un municipio del estado de São Paulo. Los "casos" incluyeron a personas que viven con VIH (PVVIH) hospitalizadas y "controla" a los pacientes ambulatorios. Las entrevistas se realizaron utilizando un instrumento con variables sociodemográficas, características clínicas y otras vulnerabilidades. Los datos fueron analizados por regresión logística condicional. Resultados: participaron 56 casos y 112 controles. Los factores de riesgo de hospitalización por VIH fueron: personas desempleadas y jubiladas; personas sin hogar; usuarios no antirretrovirales; individuos que no asistieron regularmente a las declaraciones. El acceso a los trabajadores sociales fue un factor protector para la hospitalización. Conclusiones: esta investigación contribuyó a medir las vulnerabilidades sociales, individuales y programáticas que interfieren con la agudización del VIH y, en consecuencia, el resultado desfavorable, como la hospitalización.

RESUMO Objetivos: identificar a associação entre as internações por HIV/aids e os fatores que integram as vulnerabilidades individuais, sociais e programáticas. Métodos: estudo caso-controle realizado em 2014 em um município do estado de São Paulo. "Casos" compreenderam pessoas que viviam com HIV (PVHIV) internadas e "controles" aquelas que faziam acompanhamento ambulatorial. Foram realizadas entrevistas utilizando um instrumento com variáveis sociodemográficas, características clínicas e outras vulnerabilidades. Os dados foram analisados por meio de regressão logística condicional. Resultados: participaram 56 casos e 112 controles. Constituíram fatores de risco para internação hospitalar por HIV: indivíduos desempregados e aposentados/do lar; pessoas em situação de rua; não usuários de antirretroviral; indivíduos que não compareciam regularmente aos retornos. Acesso à assistente social constituiu-se um fator de proteção para internação. Conclus ões: esta investigação contribuiu para mensurar as vulnerabilidades sociais, individuais e programáticas que interferem na agudização do HIV e, consequentemente, no desfecho desfavorável, como a internação hospitalar.

HIV-related nephropathy: new aspects of an old paradigm

SUMMARY The scenario of infection by the human immunodeficiency virus (HIV) has been undergoing changes in recent years, both in relation to the understanding of HIV infection and regarding the treatments available. As a result, the disease, which before was associated with high morbidity and mortality, is now seen as a chronic disease that can be controlled, regarding both transmission and symptoms. However, even when the virus replication is well controlled, the infected patient remains at high risk of developing renal involvement, either by acute kidney injury not associated with HIV, nephrotoxicity due to antiretroviral drugs, chronic diseases associated with increased survival, or glomerular disease associated to HIV. This review will cover the main aspects of kidney failure associated with HIV.

RESUMO O panorama da infecção pelo vírus da imunodeficiência humana (HIV) vem sofrendo alterações nos últimos anos, tanto em relação ao entendimento da infecção pelo HIV quanto aos tratamentos disponíveis. Como resultado, a doença, que antes estava associada a alta morbimortalidade, é agora considerada uma doença crônica que pode ser controlada, tanto em relação à transmissão quanto aos sintomas. No entanto, mesmo quando a replicação viral é bem controlada, o paciente infectado tem um alto risco de desenvolver complicações renais, seja através de lesão renal aguda não relacionada ao HIV, por nefrotoxicidade causada por drogas antirretrovirais, por doenças crônicas associadas com o aumento da sobrevida ou por doença glomerular associada ao HIV. Esta revisão abordará os principais aspectos da insuficiência renal associada ao HIV.

Prevalence and risk factors for erectile dysfunction in HIV-infected patients in Salvador, Brazil

ABSTRACT Background: Effective antiretroviral therapy (ART) has increased life expectancy for HIV patients to levels close to that observed for general population. Comorbidities are also increasing, due to ageing of such population. Erectile dysfunction (ED) has been a frequent finding in men living with HIV. Objectives: The goals of the present study were to define the prevalence of ED and associated factors in HIV-infected men, in a referral center of Salvador city, Brazil. Methods: HIV-infected men ≥18 years of age, receiving care at the AIDS Clinics of Complexo Hospitalar Professor Edgard Santos (C-HUPES), Universidade Federal da Bahia were consecutively included in the study until the estimated sample size (N = 134) was reached. Patients filled a structured questionnaire on clinical-epidemiological characteristics, as well as the International Index on Erectile Function to assess ED. Results: Most (55%) were black and single (79%), mean age 44.8 years. ED was detected in 29 (21.6%) patients; 86% of ED cases were classified as severe. The only factors associated with ED were low income (p = 0.02) and unemployment (p = 0.01). No association was found between ED and frequency of comorbidities, age, or ART used by patients. Conclusion: In a referral center in Salvador city, socio-economic problems were the main factors associated with ED. Psychological impact of poor social conditions should be routinely assessed in patients with ED to implement preventive measures for ED.

Microbiological study of the subgingival biofilm in HIV+/HAART patients at a specialized dental service / Estudio microbiológico del biofilm subgingival de pacientes VIH+ bajo TARGA en un servicio dental especializado

ABSTRACT The aim of this study was to describe the microbiological profile of HIV patients under highly active antiretroviral treatment (HAART). This crosssectional study comprised 32 HIV patients with periodontal disease (PD) who had been under HAART for more than 6 months. Information about the patients' medical history was obtained from clinical records. Clinical dental examination was performed by a calibrated researcher using standard dental instruments to determine probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP). A total 4,765 periodontal sites were evaluated, 125 of which were also studied microbiologically. Subgingival biofilm samples were obtained using sterile paper points; one set was used for microbiological culture studies and the other for endpoint PCR. Statistical analysis was performed using KruskalWallis and posthoc DunnBonferroni contrast tests. All participants were on HAART at the time of the study, and 90.6% had a viral load below 50 copies/mm3. Prevalence of periodontally active sites was low in the study population. Microbiological studies: Black pigmented anaerobic bacteria and fusiform CFU counts were significantly higher in samples from sites with BOP and PD ≥4mm (p 0.020 and p 0.005, respectively). Molecular Assays: Detection of Porphyromonas gingivalis (p 0.002), Tannerella forsythia (p 0.023) and Treponema denticola (p 0.015) was significantly more frequent at sites with BOP and PD ≥4mm. Conclusions: The patients living with HIV/AIDS under HAART studied here had low prevalence of clinical periodontal disease signs. However, significant detection of P. gingivalis, T. denticola, and T. forsythia in periodontal active sites, and the involvement of these microorganisms as potential HIV reactivators, show the importance of creating awareness among dental health professionals of the need for close dental and periodontal monitoring in HIV patients.

RESUMEN El objetivo de este estudio fue describir el perfil microbiológico del biofilm subgingival de los pacientes con VIH bajo tratamiento antirretroviral de alta actividad (TARGA). El estudio comprendió a 32 pacientes VIH seropositivos con enfermedad periodontal (EP) que se encontraran en tratamiento con TARGA por más de 6 meses. Los antecedentes médicos de los pacientes se obtuvieron de las historias clínicas. El examen clínico instrumental (profun didad de sondaje (PS), nivel de inserción clínico (NIC) y sangrado al sondaje (SS)) fue realizado con instrumental odontológico estándar por un investigador calibrado. De este modo, se evaluaron un total de 4.765 sitios periodontales de los cuales 125 fueron estudiados microbiológicamente. Las muestras de biope lícula subgingival se obtuvieron empleando conos de papel estéril. Las muestras se emplearon en estudios microbiológicos y moleculares por PCR de punto final. El análisis estadístico se realizó según KruskalWallis y pruebas de contrastes posthoc de DunnBonferroni. El 90,6% de la población en estudio presentó carga viral inferior a 50 copias/mm3. La prevalencia de sitios periodontales activos fue baja (1%). Los recuentos de bacterias anaerobias estrictas pigmentadas de negro y fusiformes fueron significativamente más altos en muestras de sitios periodontales con SS positivo y PS ≥4 mm (p 0.020 y p 0.005). La detección molecular de Porphyromonas gingivalis (p 0.002), Tannerella forsythia (p 0.023) y Treponema denticola (p 0.015) fue significativamente mayor en los sitios con SS y PS ≥4mm. La prevalencia del 1% de enfermedad periodontal en el grupo de pacientes estudiados fue menor a la esperada, sin embargo; la detección significativa de P. gingivalis, T. denticola y T. forsythia en sitios periodontales activos y su potencial participación como agentes reactivadores del VIH, nos alerta de la importancia de crear conciencia en los profesionales de la salud (médicos y odontólogos) acerca de la necesidad de un monitoreo minucioso del estado periodontal de pacientes con características semejantes a las descriptas en la muestra poblacional estudiada.

Social representations of the elderly about HIV/AIDS / Representaciones sociales de ancianos soropositivos acerca del VIH/SIDA / Representações sociais de idosos soropositivos acerca do hiv/aids

ABSTRACT Objective: to understand the representational content about HIV/AIDS among seropositive elderly people. Method: a qualitative study carried out from April to May 2017, in the city of Recife/PE, with 48 seropositive elderly people, through a semi-structured interview. The Social Representations Theory was used as theoretical framework and the method of lexical analysis through IRAMUTEQ software. Results: it was observed that the social representation of HIV is structured around the proximity of death and that it is a disease of restricted groups, leading to feelings of sadness. On the other hand, it is evident a transformation of the representation linked to the reified knowledge, leading to the process of naturalization of the disease. Final considerations: it is concluded that the elderly living with HIV, when they undergo a process of reframing about the disease, become more flexible to deal with their condition of seropositivity.

RESUMEN Objetivo: aprehender los contenidos representacionales acerca del VIH/SIDA entre personas mayores seropositivas. Método: la investigación cualitativa, realizada de abril a mayo de 2017, en el municipio de Recife/PE, con 48 personas ancianas seropositivas, por medio de una entrevista semiestructurada. Se utilizó la Teoría de las Representaciones Sociales como referencial teórico y el método de análisis léxico a través del software IRAMUTEQ. Resultados: se observó que la representación social del VIH se estructura en torno a la proximidad de la muerte y de que es una enfermedad de grupos restringidos, llevando a sentimientos de tristeza. Por otro lado, se evidencia una transformación de la representación ligada al conocimiento reificado, conduciendo al proceso de naturalización de la enfermedad. Consideraciones finales: se concluye que los ancianos que viven con VIH, al pasar por un proceso de resignificación sobre la enfermedad, se vuelven más flexibles para lidiar con su condición de seropositividad.

RESUMO Objetivo: apreender os conteúdos representacionais acerca do HIV/Aids entre pessoas idosas soropositivas. Método: pesquisa qualitativa, realizada de abril a maio de 2017, no município de Recife/PE, com 48 pessoas idosas soropositivas, por meio de entrevista semiestruturada. Utilizou-se a Teoria das Representações Sociais como referencial teórico e o método de análise lexical através do software IRAMUTEQ. Resultados: observou-se que a representação social do HIV se estrutura em torno da proximidade da morte e de que é uma doença de grupos restritos, levando a sentimentos de tristeza. Por outro lado, evidencia-se uma transformação da representação ligada ao conhecimento reificado, conduzindo ao processo de naturalização da doença. Considerações finais: conclui-se que os idosos que vivem com HIV, ao passarem por um processo de ressignificação acerca da doença, se tornam mais flexíveis para lidar com a sua condição de soropositividade.

Actinomicosis esofágica en pacientes con infección por VIH / Esophageal actinomycosis in patients with HIV infection

La patología esofágica es común en pacientes con VIH, frecuentemente debido a Candida, citomegalovirus o virus herpes simple. Sin embargo, la actinomicosis esofágica es una infección rara, incluso en pacientes con infección VIH. Reportamos el caso en un paciente varón de 33 años, con diagnóstico reciente de VIH que acudió a consulta por fiebre, odinofagia, disfagia y dolor retroesternal. La endoscopia digestiva alta evidenció múltiples úlceras esofágicas y el informe histopatológico de la biopsia esofágica describió una esofagitis crónica con presencia de colonias de bacilos PAS positivos, compatibles con Actinomyces, iniciando tratamiento antimicrobiano con evolución favorable. Aunque es una enfermedad no común, cerca de un tercio de los casos de actinomicosis esofágica se presentan en pacientes con infección VIH, y es preciso el estudio endoscópico con toma de biopsia para definir el diagnóstico y manejo apropiado.

Esophageal pathology is common in patients with HIV, frequently due to Candida, cytomegalovirus or herpes virus. However, esophageal actinomycosis is a rare infection, even in patients with HIV. We report the case of a 33-year-old male patient, with a recent diagnosis of HIV who was admitted for fever, odynophagia, dysphagia and retrosternal pain. Upper gastrointestinal endoscopy evidenced multiple esophageal ulcers and the histopathological report of the esophageal biopsy described a chronic esophagitis with colonies of PAS positive bacilli, compatible with Actinomyces, initiating favorable antimicrobial therapy. Although it is an uncommon disease, about one-third of cases of esophageal actinomycosis occur in patients with HIV infection, and endoscopic biopsies are required to define diagnosis and appropriate treatment.

Epidemiological, clinical, and laboratory factors associated with chronic kidney disease in Mexican HIV-infected patients / Fatores epidemiológicos, clínicos e laboratoriais associados à doença renal crônica em pacientes mexicanos infectados pelo HIV

ABSTRACT Aim: To determine the prevalence of chronic kidney disease (CKD) and the epidemiological, clinical, and laboratory factors associated with CKD in Mexican HIV-infected patients. Methods: Cross-sectional study. We included 274 patients with HIV/AIDS. CKD was defined by the estimated glomerular filtration rate (eGFR < 60 mL/min/1.73 m2 assessed by CKD-EPI) and albuminuria criteria from KDIGO guidelines. Clinical, epidemiological, and laboratory characteristics were compared between patients with and without CKD. The factors associated with CKD were assessed by logistic regression analysis. Results: The mean age was 41±11 years, and 72.3% of the patients were men. The global prevalence of CKD was 11.7% (n = 32); 7.2% (n = 20) were defined by eGFR criterion; 7.6% (n = 21), by the albuminuria criterion; and 3.2% (n = 9), by both CKD criteria. The most frequently observed stages of CKD were KDIGO G3A1 stage with 4.7% (n = 13), KDIGO G1A2 stage with 3.6% (n = 10) and KDIGO G3A2 stage with 1.7% (n = 5). The factors associated with CKD were use of abacavir/lamivudine (OR 3.2; 95% CI 1.1-8.9; p = 0.03), a CD4 lymphocyte count < 400 cells/µL (OR 2.6; 95% 1.03-6.4, p = 0.04), age (OR 1.1; 95% CI 1.04-1.2, p = 0.001) and albuminuria (OR 19.98; 95% CI: 5.5-72.2; p < 0.001). Conclusions: CKD was a frequent complication in HIV-infected patients. These findings confirm the importance of screening and the early detection of CKD, as well as the importance of identifying and treating traditional and non-traditional risk factors associated with CKD.

RESUMO Objetivo: Determinar a prevalência de doença renal crônica (DRC) e os fatores epidemiológicos, clínicos e laboratoriais associados à DRC em pacientes mexicanos infectados pelo HIV. Métodos: Estudo transversal. Incluímos 274 pacientes com HIV/AIDS. A DRC foi definida pela taxa de filtração glomerular estimada (TFGe < 60 mL/min/1,73 m2, avaliada pelo CKD-EPI) e pelos critérios de albuminúria das diretrizes do KDIGO. As características clínicas, epidemiológicas e laboratoriais foram comparadas entre pacientes com e sem DRC. Os fatores associados à DRC foram avaliados por análise de regressão logística. Resultados: A média da idade foi de 41 ± 11 anos e 72,3% dos pacientes eram homens. A prevalência global de DRC foi de 11,7% (n = 32); 7,2% (n = 20) foram definidos pelo critério TFGe; 7,6% (n = 21), pelo critério da albuminúria; e 3,2% (n = 9), pelos dois critérios para DRC. Os estágios mais frequentemente observados da DRC foram o estágio KDIGO G3A1 com 4,7% (n = 13); estágio KDIGO G1A2 com 3,6% (n = 10) e estágio KDIGO G3A2 com 1,7% (n = 5). Os fatores associados à DRC foram o uso de abacavir/lamivudina (OR 3,2; IC95% 1,1-8,9; p = 0,03), contagem de linfócitos CD4 < 400 células/µL (OR 2,6; 95% 1,03-6,4, p = 0,04), idade (OR 1,1; IC95% 1,04-1,2, p = 0,001) e albuminúria (OR 19,98; IC95%: 5,5-72,2; p < 0,001). Conclusões: A DRC foi uma complicação frequente em pacientes infectados pelo HIV. Esses achados confirmam a importância do rastreamento e da detecção precoce da DRC, bem como a importância de identificar e tratar os fatores de risco tradicionais e não tradicionais associados à DRC.

HTLV 1/2 Prevalence and risk factors in individuals with HIV/AIDS in Pernambuco, Brazil

Abstract INTRODUCTION: Apart from masking the diagnosis of AIDS in patients with HIV/AIDS, human T-cell lymphotropic virus (HTLV), when present, also increases the risk of myelopathies and neurological disease in these patients. METHODS: Disease prevalence was estimated by ELISA and confirmed by Western blot. RESULTS: The coinfection rate was 1.5% (11/720); 10 of 11 patients had HTLV-1, and the remaining one had HTLV-2. The majority were male, over 40 years old, and of pardo color (ethnicity). CONCLUSIONS: There was no association between the risk factors examined and HTLV/HIV coinfection. This is the first study to report the occurrence of HTLV-2 in Pernambuco.

Influence of exposure and vertical transmission of HIV-1 on the neuropsychomotor development in children

Abstract INTRODUCTION: Exposure to human immunodeficiency virus (HIV)-1 during pregnancy is a major risk factor for neurodevelopmental delay and deleterious effects in children. However, limited information about these conditions exists in poor geographical areas in Brazil. Prevention of vertical transmission of HIV-1 is dealt differently in different regions of the country and in poorer areas it is more difficult to evaluate the impact of the prevention methods. The outcomes of the exposure to HIV-1 and the impact of vertical HIV-1 transmission on neuropsychomotor development was evaluated for the first time in children born to HIV-infected mothers in the North region of Brazil, where the majority of the population has poor access to health services. METHODS: Sixty children born to HIV-1-infected mothers (case group) and 58 born to non-infected mothers (control group) were followed for the first 12 months of life in a prospective case-control study. Neuropsychomotor development was assessed using the Denver II test. RESULTS: Suspected neuropsychomotor developmental delays were more frequent in the case group (33.3%), namely in language (38.9%) and gross motor skills (27.8%). These delays were reversed in most children after 12 months of life due to therapeutic intervention. The delays were not reversed in three children, all of whom belonged to the case group. Only one of these was infected with HIV-1, and this child had the poorest neuropsychomotor outcomes. CONCLUSIONS: Maternal HIV-1 infection negatively affected the neuropsychomotor development in children, although other factors may have played a role.

Absence of cytomegalovirus in gingivitis and chronic periodontitis in HIV-1 patients in Northern Brazil

Abstract INTRODUCTION The influence of cytomegalovirus (CMV) on the progression of chronic periodontitis in HIV patients is poorly investigated. METHODS ELISA was used for anti-CMV antibody IgG titer measurements and real-time polymerase chain reaction for qualitative and quantitative CMV detection. Data on the CD4 + T lymphocyte count and plasma HIV viral load were obtained from patient records. RESULTS CMV DNA was detected in samples of subgingival biofilm in only three individuals, two of them with chronic periodontitis (4%) and one with gingivitis (3.3%). CONCLUSIONS The prevalence of CMV is very low both in HIV-1 patients with gingivitis and chronic periodontitis.

Prevalence and risk factors of mild chronic renal failure in HIV-infected patients: influence of female gender and antiretroviral therapy

ABSTRACT Background In people living with HIV, much is known about chronic kidney disease, defined as a glomerular filtration rate under 60 mL/min. However, there is scarce data about prevalence and risk factors for milder impairment (60-89 mL/min). Objective The present study aims to assess the influence of sex, antiretroviral therapy, and classical risk factors on the occurrence of mild decreased renal function in a large Spanish cohort of HIV-infected patients. Methods Cross-sectional, single center study, including all adult HIV-1-infected patients under antiretroviral treatment with at least two serum creatinine measures during 2014, describing the occurrence of and the risk factors for mildly decreased renal function (eGFR by CKD-EPI creatinine equation of 60-89 mL/min). Results Among the 4337 patients included, the prevalence rate of mildly reduced renal function was 25%. Independent risk factors for this outcome were age older than 50 years (OR 3.03, 95% CI 2.58-3.55), female sex (OR 1.23, 95% CI 1.02-1.48), baseline hypertension (OR 1.57, 95% CI 1.25-1.97) or dyslipidemia (OR 1.48, 95% CI 1.17-1.87), virologic suppression (OR 1.88, 95% CI 1.39-2.53), and exposure to tenofovir disoproxil-fumarate (OR 1.67, 95% CI 1.33-2.08) or ritonavir-boosted protease-inhibitors (OR 1.19, 95% CI 1.03-1.39). Conclusions Females and patients over 50 seem to be more vulnerable to renal impairment. Potentially modifiable risk factors and exposure to tenofovir disoproxil-fumarate or ritonavir-boosted protease-inhibitors are present even in earlier stages of chronic kidney dysfunction. It remains to be determined whether early interventions including antiretroviral therapy changes (tenofovir alafenamide, cobicistat) or improving comorbidities management will improve the course of chronic kidney disease.

Acute kidney injury and other factors associated with mortality in hiv-infected patients

SUMMARY OBJECTIVE: HIV-related mortality is still high, especially in developed countries. The aim of this study is to investigate factors associated to death in HIV-infected patients. METHODS: This is a cross-sectional study with all HIV adult patients admitted to a tertiary infectious diseases hospital in Fortaleza, Northeast Brazil, from January 2013 to December 2014. Patients were divided into two groups: survivors and non-survivors. Demo-graphical, clinical and laboratory data were compared and a logistic regression was performed in order to investigate risk factors for death. P values ≤0.05 were considered statistically significant. RESULTS: A total of 200 patients with mean age of 39 years were including in the study, 69.5% males. Fifteen patients (7.5%) died. Non-survivors presented a higher percentage of males (93.3 vs. 67.3%, p = 0.037). Non-survivors presented AKI (73.3 vs. 10.3%, p < 0.001), liver dysfunction (33.3 vs. 11.5, p = 0.031), dyspnea (73.3 vs. 33.0%, p = 0.002) and disorientation (33.3 vs. 12.4%, p = 0.025) more frequently. Non-survivors also had higher levels of urea (73.8 ± 52.7vs. 36.1 ± 29.1 mg/dL, p < 0.001), creatinine (1.98 ± 1.65 vs. 1.05 ± 1.07 mg/dL, p < 0.001), aspartate aminotransferase (130.8 vs. 84.8 U/L, p = 0.03), alanine aminotransferase (115.6 vs. 85.4 U/L, p = 0.045) and lactate dehydrogenase (LDH) (1208 vs. 608 U/L, p = 0.012), as well as lower levels of bicarbonate (18.0 ± 4.7 vs. 21.6 ± 4.6 mEq/L, p = 0.016) and PCO2 (27.8 ± 7.7 vs. 33.0 ± 9.3 mmHg, p = 0.05). In multivariate analysis, disorientation (p = 0.035, OR = 5.523, 95%CI = 1.130 - 26.998), dyspnoea (p = 0.046, OR = 4.064, 95%CI = 1.028 - 16.073), AKI (p < 0.001, OR = 18.045, 95%CI = 4.308 - 75.596) and disseminated histoplasmosis (p = 0.016, OR = 12.696, 95%CI = 1.618 - 99.646) and LDH > 1000 U/L (p = 0.038, OR = 4.854, 95%CI = 1.093 - 21.739) were risk factors for death.]CONCLUSION: AKI and disseminated histoplasmosis (DH) were the main risk factors for death in the studied population. Neurologic and respiratory impairment as well as higher levels of LDH also increased mortality in HIV-infected patients.

RESUMO INTRODUÇÃO: A mortalidade relacionada ao HIV ainda é alta, especialmente nos países em desenvolvimento. O objetivo deste estudo é investigar os fatores associados ao óbito em pacientes com HIV. MÉTODOS: Trata-se de um estudo transversal com todos os pacientes com HIV admitidos consecutivamente em um hospital terciário de doenças infecciosas em Fortaleza, Nordeste do Brasil, entre janeiro de 2013 e dezembro de 2014. Os pacientes foram divididos em dois grupos: sobreviventes e não sobreviventes. Dados demográficos, clínicos e laboratoriais foram comparados e análise de regressão logística foi feita para investigação dos fatores de risco para óbito. RESULTADOS: Um total de 200 pacientes, com média de idade de 39 anos, foi incluído no estudo, sendo 69,5% do sexo masculino. Óbito ocorreu em 15 pacientes (7,5%). Os não sobreviventes apresentaram maior percentual de homens (93,3 vs. 67,3%, p = 0,037) e um menor tempo de internação (8 ± 6 vs. 18 ± 15 dias, p = 0,005). Na análise multivariada, desorientação (p = 0,035, OR = 5,523), dispneia (p = 0,046, OR = 4,064), LRA (p < 0,001, OR = 18,045), histoplasmose disseminada (p = 0,016, OR = 12,696) e desidrogenase lática (LDH) > 1.000 U/L (p = 0,038, OR = 4,854) foram fatores de risco para óbito. CONCLUSÕES: LRA e histoplasmose disseminada foram os principais fatores de risco para óbito na população estudada. Distúrbios neurológicos e respiratórios, bem como níveis elevados de LDH, também estiveram associados com o aumento da mortalidade em pacientes com HIV.

Frequency of Subclinical Atherosclerosis in Brazilian HIV-Infected Patients / Frequência de Aterosclerose Subclínica em Brasileiros Infectados pelo HIV

Abstract Background: AIDS as well as atherosclerosis are important public health problems. The longer survival among HIV-infected is associated with increased number of cardiovascular events in this population, and this association is not fully understood. Objectives: To identify the frequency of subclinical atherosclerosis in HIV-infected patients compared to control subjects; to analyze associations between atherosclerosis and clinical and laboratory variables, cardiovascular risk factors, and the Framingham coronary heart disease risk score (FCRS). Methods: Prospective cross-sectional case-control study assessing the presence of subclinical atherosclerosis in 264 HIV-infected patients and 279 controls. Clinical evaluation included ultrasound examination of the carotid arteries, arterial stiffness by pulse wave velocity (PWV) and augmentation index (AIx), laboratory analysis of peripheral blood, and cardiovascular risk according to FCRS criteria. The significance level adopted in the statistical analysis was p < 0.05. Results: Plaques were found in 37% of the HIV group and 4% of controls (p < 0.001). Furthermore, carotid intima-media thickness was higher in the HIV group than in controls (p < 0.001). Patients with carotid plaque had higher fasting glucose, total cholesterol, low-density lipoprotein cholesterol, and triglycerides than those without plaques. The presence of HIV, adjusted for age, overweight/obesity, and smoking increased by almost fivefold the risk of atherosclerotic carotid plaque (OR: 4.9; 95%CI: 2.5-9.9; p < 0.001). Exposure to protease inhibitors did not influence carotid intima-media thickness, was not associated with carotid plaque frequency, and did not alter the mechanical characteristics of the arterial system (PWV and AIx). Conclusions: HIV-infected patients are at increased risk of atherosclerosis in association with classical cardiovascular risk factors. Treatment with protease inhibitors does not promote functional changes in the arteries, and shows no association with increased frequency of atherosclerotic plaques in carotid arteries. The FCRS may be inappropriate for this population.

Resumo Fundamento: Aterosclerose e AIDS são importantes problemas de saúde pública. A maior sobrevida de indivíduos infectados pelo HIV acha-se associada com maior número de eventos cardiovasculares nessa população, mas tal associação ainda não foi completamente esclarecida. Objetivos: Identificar a frequência de aterosclerose subclínica em pacientes infectados pelo HIV em comparação a controles; analisar as associações entre aterosclerose e variáveis clínicas e laboratoriais, fatores de risco cardiovascular e escore de risco de Framingham (ERF) para doença coronariana. Métodos: Estudo prospectivo transversal caso-controle avaliando a presença de aterosclerose subclínica em 264 pacientes infectados pelo HIV e 279 controles. A avaliação clínica incluiu ultrassonografia das artérias carótidas, análise da rigidez arterial através da velocidade de onda de pulso (VOP) e augmentation index (AIx), exames laboratoriais do sangue periférico e determinação do risco cardiovascular segundo os critérios do ERF. O nível de significância adotado na análise estatística foi p < 0,05. Resultados: Placas foram identificadas em 37% do grupo infectado pelo HIV e em 4% dos controles (p < 0,001). A espessura médio-intimal carotídea foi maior no grupo HIV do que nos controles (p < 0,001). Pacientes com placa carotídea apresentaram maiores níveis de glicemia de jejum, colesterol total, colesterol da lipoproteína de baixa densidade e triglicérides do que aqueles sem placas. A presença do HIV, ajustada por idade, sobrepeso/obesidade e tabagismo aumentou em quase cinco vezes o risco de placa aterosclerótica carotídea (OR: 4,9; IC95%: 2,5-9,9; p < 0,001). Exposição aos inibidores da protease não influenciou a espessura médio-intimal carotídea, não se associou com frequência de placa carotídea e não alterou as características mecânicas do sistema arterial (VOP e AIx). Conclusões: Pacientes infectados pelo HIV apresentam maior risco de aterosclerose na associação com os clássicos fatores de risco cardiovascular. Tratamento com os inibidores da protease não promove alterações funcionais nas artérias, nem se associa com maior frequência de placas ateroscleróticas carotídeas. O ERF pode ser inadequado para essa população.
