Avaliação da cascata de cuidado contínuo em indivíduos com HIV/AIDS em um centro ambulatorial de referência no Nordeste do Brasil / Evaluación de la cascada de cuidados en individuos con VIH/SIDA en un centro ambulatorio de referencia en el Nordeste de Brasil / Evaluation of the care cascade in individuals with HIV/AIDS at an ambulatory reference center in Northeast Brazil

HISTÓRICO: A cascata de cuidado contínuo surgiu como uma estratégia para se transpor a infecção por HIV e se alcançar o objetivo final em cuidados, que seria a supressão viral. Este estudo tem como objetivo descrever a cascata de cuidado contínuo em indivíduos com HIV/AIDS em um Serviço Ambulatorial Especializado. METODOLOGIA: Esse é um estudo de coorte retrospectivo que analisou indivíduos adultos com diagnóstico confirmado de HIV/AIDS e que iniciaram seu acompanhamento no Núcleo de Atenção Médica Integrada (NAMI) da Universidade de Fortaleza (UNIFOR), cidade de Fortaleza, estado do Ceará, na região Nordeste do Brasil. Os dados que se seguem foram usados na pesquisa: carga viral CD4+/CD8+ e carga viral do HIV. Os participantes foram classificados em dois grupos: retidos no cuidado em saúde (grupo 1) e não retidos no cuidado em saúde (grupo 2), totalizando uma coorte de 511 participantes. RESULTADO: A análise univariada entre os grupos demonstrou que havia predominância significativa de pacientes homens com média de idade mais alta no grupo 1 (p = 0,01). Um histórico prévio de dependência química, e na primeira consulta, foi mais frequente no grupo 2 (p = 0,001 e p = 0,01 respectivamente). Os pacientes do grupo 1 tinham um histórico mais frequente de infecções sexualmente transmissíveis (IST) (p=0,002) e estavam mais imunossuprimidos quando do diagnóstico (p = 0,002). O uso de terapia antirretroviral (TARV) na primeira consulta foi mais significativo no grupo de pacientes retidos (p<0,001). CONCLUSÕES: Este estudo sugere a necessidade de aprimoramento da "cascata de cuidados" através de sua expansão, na medida em que considere riscos comportamentais dinâmicos, o que poderia transpor as barreiras sistêmicas de acesso aos serviços de saúde para as pessoas que vivem com HIV/AIDS.

ANTECEDENTES: La cascada constante de tratamiento/cuidados ha emergido como una estrategia a fin de dejar atrás la infección por VIH en busca de la meta última del tratamiento, que es la supresión viral. El estudio apunta a describir la cascada de cuidados en individuos con VIH/SIDA en un Servicio Ambulatorio Especializado. MÉTODOS: El diseño del estudio es un grupo retrospectivo de individuos adultos con diagnosis confirmada del VIH/SIDA, quienes iniciaron su seguimiento en el Centro de Cuidados Médicos Integrados (NAMI) de la Universidad de Fortaleza (UNIFOR), en la ciudad de Fortaleza, estado de Ceará, en el nordeste de Brasil. Las informaciones siguientes fueron utilizadas en la investigación: CD4+/CD8+ carga viral y carga viral del VIH/SIDA. Los individuos fueron clasificados en dos grupos: retenidos (grupo 1) y no retenidos (grupo 2), totalizando una muestra de 511 participantes. RESULTADOS: El análisis de variable única entre estos grupos demostró que había una predominancia significativa de pacientes masculinos con una edad promedio más elevada en el grupo 1 (p = 0.01). Un antecedente de adicción previa a narcóticos durante la primera consulta fue más frecuente en el segundo grupo (p = 0.001 y p = 0.01 respectivamente). Los pertenecientes al grupo 1, de manera más frecuente, tenían antecedentes de infecciones sexualmente transmitidas (IST) (p = 0.002) y estaban más inmunosuprimidos a la época del diagnóstico (p = 0.002). El uso de TARV (terapia antirretroviral) en la primera consulta fue también más significativo en el grupo de pacientes retenidos (p <0.001). CONCLUSIONES: El estudio sugiere la necesidad de mejorar la "cascada de tratamiento/cuidados" mediante su expansión, a fin de abordar los riesgos de conducta dinámica, lo cual puede transponer las barreras sistémicas de acceso a los servicios de salud para las personas que conviven con VIH/SIDA.

BACKGROUND: The continuous care cascade has emerged as a strategy to transpose HIV infection to attain the ultimate goal of care, which is viral suppression. The study aims to describe the care cascade in individuals with HIV / AIDS in a Specialized Ambulatory Service. METHODS: The study design is a retrospective cohort of adult individuals with a confirmed diagnosis of HIV/AIDS who initiated their follow-up at the Integrated Medical Care Center (NAMI) of Universidade de Fortaleza (UNIFOR), in the city of Fortaleza, state of Ceará, northeastern Brazil. The following data were used in the investigation: CD4+/CD8+ viral load and HIV viral load. The subjects were classified into two groups: retained (group 1) and non-retained (group 2), totaling a sample of 511 participants. RESULTS: The univariate analysis between these groups showed that there was a significant predominance of male patients with a higher mean age in group 1 (p = 0.01). A history of previous drug addiction and at the first consultation was more frequent in the second group (p = 0.001 and p = 0.01 respectively). Patients from group 1 more often had a history of sexually-transmitted infections (STIs) (p = 0.002) and were more immunosuppressed at the time of diagnosis (p = 0.002). The use of ART at the first consultation was also more significant in the group of retained patients (p <0.001). CONCLUSIONS: The study suggests a need to improve the "cascade of care" by expanding it to address dynamic behavioral risks, which can transpose the systemic barriers of access to health services for people living with HIV/AIDS.

Dengue: 30 years of cases in an endemic area

The present study aimed to review literature on studies of dengue cases conducted over 30 years in the state of Ceará. Between November 2015 and January 2016, articles published in Portuguese and English in 7 databases were searched using keywords and a Boolean operator. A total of 191 articles were identified in the databases; 133 were excluded according to the exclusion criteria, and 58 were included in the study. Of the 58 articles analyzed, 6 reported data from Brazil; including the Northeast region and the state of Ceará; 41 reported data for only the city of Fortaleza; 7 reported data for the state of Ceará; 4 reported data for cities in the interior of the state; and 3 included only children. The studies adopted different approaches and focused on different aspects of the disease. Study outcomes included the identification of serological, epidemiological, clinical, and laboratory characteristics; potential larvicides and biological predators of mosquitoes; potential antiviral agents; vector density characteristics; and educational dengue prevention and control strategies. Additionally, one vaccine trial was included. Although studies on dengue in the state of Ceará are scarce, they are encompassing, including several lines of research, and the number of studies and reports on dengue in the state of Ceará continues to increase.

Is early HIV infection diagnosis at a reference center a reality in the state of Ceara?

Abstract INTRODUCTION: Early diagnosis of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) can decrease transmission and significantly affect morbidity and mortality; however, Brazil still confronts the reality of late HIV diagnosis. METHODS: Medical records of 284 HIV-positive patients were reviewed in this cross-sectional study. RESULTS: Of all patients, 28% were diagnosed in the context of health assessments, whereas 27% were symptomatic at diagnosis. Early HIV infection (Group 1) was diagnosed in 60.2% of participants. They were younger than those with late diagnosis (Group 2) (p = 0.002). CONCLUSIONS: These findings highlight the need for strategies to increase HIV testing in asymptomatic individuals and older patients.

Is Visceral Leishmaniasis the same in HIV-coinfected adults?

ABSTRACT Introduction: Visceral Leishmaniasis is the most severe form of disease caused by the Leishmania donovani complex, with significant morbidity and mortality in developing countries. Worse outcomes occur among HIV-positive individuals coinfected with Leishmania. It is unclear, however, if there are significant differences on presentation between Visceral Leishmaniasis patients with or without HIV coinfection. Methods: We reviewed medical records from adult patients with Visceral Leishmaniasis treated at a reference healthcare center in Fortaleza - Ceará, Brazil, from July 2010 to December 2013. Data from HIV-coinfected patients have been abstracted and compared to non-HIV controls diagnosed with Visceral Leishmaniasis in the same period. Results: Eighty one HIV-infected patients and 365 controls were enrolled. The diagnosis in HIV patients took significantly longer, with higher recurrence and death rates. Kala-azar's classical triad (fever, constitutional symptoms and splenomegaly) was less frequently observed in Visceral Leishmaniasis-HIV patients, as well as jaundice and edema, while diarrhea was more frequent. Laboratory features included lower levels of hemoglobin, lymphocyte counts and liver enzymes, as well as higher counts of blood platelets and eosinophils. HIV-infected patients were diagnosed mainly through amastigote detection on bone marrow aspirates and treated more often with amphotericin B formulations, whereas in controls, rK39 was the main diagnostic tool and pentavalent antimony was primarily used for treatment. Conclusions: Clinical and laboratory presentation of Visceral Leishmaniasis in HIV-coinfected patients may differ from classic kala-azar, and these differences may be, in part, responsible for the delay in diagnosing and treating leishmaniasis, which might lead to worse outcomes.

HIV and dementia: prevalence and risk factors / HIV e demência: prevalência e fatores de risco / VIH y demencia: prevalencia y factores de riesgo

Objective: To determine the prevalence of patients at risk of developing HIV-associated neurocognitive disorder (HAND) and identify factors possibly associated with its occurence. Methods: Quantitative cross-sectional study conducted at the Specialized Care Service (Serviço de Atendimento Especializado - SAE) for HIV/Aids of the Integrated Medical Care Center (Núcleo de Atendimento Médico Integrado - NAMI) of the University of Fortaleza (Universidade de Fortaleza - UNIFOR), Fortaleza, Ceará, Brazil. We reviewed medical records of all 249 patients that started medical follow-up at SAE/NAMI since its foundation (August/2010) until January/2014, including in the analysis those who completed the international HIV dementia scale - IHDS during routine medical visits. Epidemiological, clinical and laboratory variables were collected in addition to IHDS score and the sample was classified in two groups: patients with IHDS≥10 (Group 1) and IHDS<10 (Group 2). Chisquared test was used for categorical variables and student t test, mann whitney test and linear regression were used for numerical variables. Results: The study population consisted of 178 patients with mean IHDS score of 9.5 (+/- 1.6). HAND prevalence was 41.6% (74/178) (IHDS<10). These patients presented older mean age (37.4 years) and longer mean time from HIV diagnosis to medical follow-up than the others (10.1 months) when compared to Group 2 (31 years old and 4.6 months, respectively), suggesting that these two variables were possibly associated with HAND occurrence. Conclusion: The IHDS application showed a high prevalence of HAND in the study population. More advanced age and longer time from HIV diagnosis to medical follow-up are possibly associated with its occurence.

Objetivo: Determinar a prevalência de pacientes sob risco de desenvolver desordem cognitiva relacionada ao HIV (HAND ­ HIV associated neurocognitive disorder) e identificar fatores que possivelmente estariam associados à sua ocorrência. Métodos: Estudo quantitativo, transversal, conduzido no Serviço de Atendimento Especializado (SAE) em HIV/AIDS do Núcleo de Atenção Médica Integrada (NAMI), Universidade de Fortaleza (UNIFOR), Fortaleza/Ceará/Brazil. Foram revisados todos os 249 prontuários de pacientes que iniciaram acompanhamento no SAE/NAMI desde a sua criação (agosto/2010) até janeiro/2014, incluindo-se na análise aqueles que apresentavam o registro da aplicação da escala de demência do HIV (IHDS ­ international HIV dementia scale) nas consultas de rotina. Coletaram-se variáveis epidemiológicas, clínicas e laboratoriais, além do valor do IHDS, classificando-se a amostra em dois grupos: pacientes com IHDS≥10 (Grupo 1) e IHDS<10 (Grupo 2). Utilizaram-se testes Qui-quadrado para variáveis categóricas, e T de Student, Mann Whitney e regressão linear para variáveis numéricas. Resultados: A população do estudo consistiu em 178 pacientes, com escore médio da IHDS de 9.5 (+/-1.6). A prevalência de HAND foi de 41,6% (74/178) (IHDS<10). Nesses pacientes, a idade média era mais elevada (37,4 anos) e o intervalo médio de tempo entre o diagnóstico do HIVe o início do acompanhamento era maior que os demais (10,1 meses), quando comparados com o Grupo 2 (31 anos e 4,6 meses respectivamente), sugerindo que essas duas variáveis possivelmente estavam associadas com a ocorrência da HAND. Conclusão: A utilização do IHDS demonstrou uma elevada prevalência de HAND na população estudada. A idade mais elevada e o intervalo de tempo maior entre o diagnóstico do HIV e o início do acompanhamento estão possivelmente relacionados com essa ocorrência.

Métodos: Estudio cuantitativo, transversal realizado en el Servicio de Atención Especializada (SAE) en VIH/SIDA del Núcleo de Atención Médica Integrada (NAMI), Universidad de Fortaleza (UNIFOR), Fortaleza/Ceará/Brasil. Se revisó todos los 249 historiales clínicos de pacientes que iniciaron seguimiento em el SAE/NAMI desde su creación (agosto/2010) hasta enero/2014, incluyéndose en el analisis aquellos que presentabam el registro de la aplicación de la escala de demencia del VIH (IHDS ­ international HIV dementia scale) en las consultas de rutina. Se recogieron variables epidemiológicas, clinicas y de laboratório además del valor del IHDS clasificando la muestra en dos grupos: pacientes con IHDS≥10 (Grupo 1) y IHDS<10 (Grupo 2). Se utilizó las pruebas Chi-cuadrado para las variables categóricas y la prueba T de Student, Mann Whitney y regresión linear para las variables numericas. Resultados: La población del estudio fue de 178 pacientes con puntuación media para la IHDS de 9.5 (+/- 1.6). La prevalencia de HAND fue del 41,6% (74/178) (IHDS<10). En eses pacientes la edad media fue más elevada (37,4 años) y el intervalo de tiempo medio entre el diagnostico del VIH y el inicio del seguimiento fue mayor que los demás (10,1 meses) al comparar con el Grupo 2 (31 años y 4,6 meses respectivamente) lo que sugiere que esas dos variables posiblemente estaban asociadas a la ocurrencia de la HAND. Conclusión: La utilización del IHDS demonstró una elevada prevalencia de HAND en la población estudiada. La edad más elevada y el intervalo de tiempo mayor entre el diagnostico del VIH y el inicio del seguimiento están posiblemente relacionados con esta ocurrencia.

O abscesso de psoas é uma entidade clínica rara com aproximadamente 12 casos relatados por ano na literatura médica e tem no Mycobacterium tuberculosis, um dos seus agentes etiológicos. O objetivo deste trabalho é relatar dois casos de tuberculose vertebral associada a abscesso de psoas atendidos em nosso serviço, bem como uma revisão da literatura.

Antiretroviral resistance mutations in human immunodeficiency virus type 1 infected patients enrolled in genotype testing at the Central Public Health Laboratory, São Paulo, Brazil: preliminary results

Antiretroviral resistance mutations (ARM) are one of the major obstacles for pharmacological human immunodeficiency virus (HIV) suppression. Plasma HIV-1 RNA from 306 patients on antiretroviral therapy with virological failure was analyzed, most of them (60 percent) exposed to three or more regimens, and 28 percent of them have started therapy before 1997. The most common regimens in use at the time of genotype testing were AZT/3TC/nelfinavir, 3TC/D4T/nelfinavir and AZT/3TC/efavirenz. The majority of ARM occurred at protease (PR) gene at residue L90 (41 percent) and V82 (25 percent); at reverse transcriptase (RT) gene, mutations at residue M184 (V/I) were observed in 64 percent. One or more thymidine analogue mutations were detected in 73 percent. The number of ARM at PR gene increased from a mean of four mutations per patient who showed virological failure at the first ARV regimens to six mutations per patient exposed to six or more regimens; similar trend in RT was also observed. No differences in ARM at principal codon to the three drug classes for HIV-1 clades B or F were observed, but some polymorphisms in secondary codons showed significant differences. Strategies to improve the cost effectiveness of drug therapy and to optimize the sequencing and the rescue therapy are the major health priorities.
