ABSTRACT

O vírus da imunodeficiência humana é o agente etiológico da AIDS, doença crônica que destrói o sistema imunológico e é caracterizada pela baixa contagem de células TCD4, alta contagem de partículas virais no sangue e manifestações clínicas da doença. O diagnóstico se dá com o aparecimento de infecções oportunistas, que levam a contagem de TCD4 a níveis menores que 200 céls/mm³. Os exames laboratoriais para o diagnóstico do HIV foram os principais avanços para o início do tratamento, reduzindo a transmissão. Detecção de anticorpos, detecção de antígenos e amplificação do genoma do vírus são alguns dos exames laboratoriais utilizados para diagnóstico. Os dois principais biomarcadores são os exames de contagem de células TCD4, que verifica o sistema imune, e a quantificação de carga viral, que informa a quantidade de partículas virais, mostrando a progressão da infecção. Quanto maior a carga viral, maior o dano ao sistema imune. Uma carga viral indetectável é inferior a 50 cópias/mL, mas valores menores ou iguais a 200 cópias/mL também impedem a transmissão. Uma declaração de consenso afirma que Indetectável é igual a Intransmissível. Portanto, quando indetectável, a transmissão inexiste. O presente estudo relata e discute o caso clínico de uma paciente diagnosticada com HIV/AIDS aos 28 anos, que sobreviveu, apesar do diagnóstico tardio, e sob presença de doença oportunista com um grave grau de diminuição de células TCD4 (22 cél/mm³). Por meio do diagnóstico, introdução e adesão correta da terapia antirretroviral e monitorização de exames laboratoriais, conseguiu evitar a morte e ter uma vida semelhante à de um HIV negativo. Ultrapassou a expectativa de vida que na descoberta era de 10 anos, com uma qualidade de vida considerável, não sendo transmissora do vírus, diminuindo assim o estigma e preconceito. O biomédico é peça fundamental nesse contexto, considerando que deve fornecer informações precisas e fidedignas, tão necessárias ao acompanhamento de pessoas vivendo com HIV, para que autoridades e profissionais de saúde adotem medidas adequadas, tanto na prevenção, quanto no diagnóstico e monitoramento da doença.


The human immunodeficiency virus is the etiological agent of AIDS, a chronic disease that destroys the immune system and is characterized by low TCD4 cell count, high viral particle count in blood and clinical manifestations of the disease. The diagnosis is due to the appearance of opportunistic infections, which lead to TCD4 counts below 200 cells / mm³. Laboratory tests for the diagnosis of HIV were the main advances in starting treatment, reducing transmission. Antibody detection, antigen detection and virus genome amplification are some of the laboratory tests used for diagnosis. The two main biomarkers are the TCD4 cell count tests, which checks the immune system, and viral load quantification, which reports the number of viral particles, showing the progression of infection. The higher the viral load, the greater the damage to the immune system. An undetectable viral load is less than 50 copies / mL, but values less than or equal to 200 copies / mL also prevent transmission. A consensus statement states that Undetectable equals Non-Transmissible. Therefore, when undetectable, transmission does not exist. The present study reports and discusses the clinical case of a patient diagnosed with HIV / AIDS at age 28, who survived despite late diagnosis and under the presence of opportunistic disease with a severe degree of TCD4 cell reduction (22 cells / mm³). Through the diagnosis, introduction and correct adherence of antiretroviral therapy and monitoring of laboratory tests, she was able to avoid death and have a life similar to that of an HIV negative. Exceeded the life expectancy that in the discovery was 10 years, with a considerable quality of life, not transmitting the virus, thus reducing the stigma and prejudice. The biomedical is a key player in this context, considering that he must provide accurate and reliable information, which is so necessary for the monitoring of people living with HIV, so that authorities and health professionals adopt appropriate measures, both in prevention, diagnosis and monitoring of the disease.

ABSTRACT

The aim of this study was to investigate possible factors related to antiretroviral therapy (ART) that contribute to the understanding of the highest rate of Aids detection on the coast of the state of Paraná, a port region identified administratively as the 1stRegional Health Division (1stHD) in the state of Paraná. Data on the sociodemographic profile of the population undergoing antiretroviral treatment (ART), medication changes, dropout of therapy, proportion of the population undergoing treatment and viral load were obtained through computerized systems. Between July 1, 2018 and June 31, 2019, 1,393 people were on ART in the 1stRS. Of these, 57.6% were male. During this period, 110 people started ART with a predominance of the age group between 30 and 39 years old. ART was switched for169 people and 211 patient dropouts were detected. The proportion of people diagnosed with HIV without treatment (gap) is still high, however 92.7% people on ART have suppressed viral load. It can be concluded that the lower educational level of the population undergoing treatment, the late diagnosis of those infected and the treatment gapprobably contribute to the highest rate of Aids detection in the 1stRS.

ABSTRACT

ABSTRACT OBJECTIVE Recognize incident infection to better characterize the groups that fuel HIV epidemic. We propose a simple score to identify recent infections among newly diagnosed patients as a HIV surveillance tool. METHODS Newly diagnosed patients were defined as recent infections when a negative serological test in the previous year was available. Laboratory tests, such as the avidity index (Bio-Rad, according to the CEPHIA protocol), chemiluminescent intensity (CMIA, architect, Abbott), and the nucleotide ambiguity index of partial pol sequences were used as proxies of recency. A simple score based on clinical symptoms of acute retroviral syndrome during the previous year, CD4+ T cell count, and viral load at admission was tested to assess the predictive power, using receiver operating characteristic (ROC) curves, to identify recent cases of infection. RESULTS We evaluated 204 recently diagnosed patients who were admitted to the Ambulatório de Referência em Moléstias Infecciosas de Santo André (Santo André Reference Infectious Diseases Outpatient Clinic), in the metropolitan region of São Paulo, Brazil, recruited between 2011 and 2018. An HIV-negative test in the year prior to enrollment was documented in 37% of participants. The proportion of cases classified as recent infections (less than one year), according to the laboratory proxies were: 37% (67/181) for an avidity index < 40%, 22% (30/137) for a CMIA < 200, and 68% (124/181) for an ambiguity index < 0.5%. Using different combinations of recency definitions, our score showed an area under the ROC curve from 0.66 to 0.87 to predict recency. CONCLUSIONS Using data from patients' interviews and routine laboratory tests at admission, a simple score may provide information on HIV recency and thus, a proxy for HIV incidence to guide public policies. This simple for the Brazilian public health system and other low- and middle-income countries.

ABSTRACT

Objective: To analyze the dynamic changes and influencing factors of HIV-1 DNA load in HIV-1 infected individuals under antiretroviral therapy (ART) in Dehong Dai and Jingpo autonomous prefecture, Yunnan province, and provide information support for the clinical use of HIV-1 DNA quantitative detection. Methods: The HIV infection cases in recent infection cohort from Dehong Center for Disease Control and Prevention during 2009-2018 were selected as study subjects. The dynamic curve of HIV-1 DNA load varrying with time was generated and logistic regression analysis was conducted to identify the risk factors for HIV-1 load in the recent follow up after ART and statistical analysis was performed by using SPSS 17.0. Results: Among the 113 HIV infection cases detected from the recent infection cohort, the recent HIV infection rate were 49.6%(56/113) males, sexual transmission cases and drug injection transmission cases accounted for 53.1% (60/113), 80.5% (91/113) and 19.5% (22/113), respectively. The dynamic changes curve showed that HIV-1 DNA load was relatively high (>800 copies /106 PBMCs) before ART, and droped rapidly (<400 copies /106 PBMCs) after ART for 1 year. However, HIV-1 DNA load decreased insignificantly from the second year of ART, and remained to be 269 copies/106 PBMCs after ART for 6 years. Univariable logistic regression analysis indicated that OR (95%CI) of CD8, CD4/CD8 and HIV-1 DNA load were 1.00 (1.00-1.00), 0.30 (0.09-1.05) and 1.01 (1.00-1.01), respectively. Multivariable logistic regression analysis showed that OR value of HIV-1 DNA load base was 1.00 (1.00-1.01). Conclusions: HIV-1 DNA load decreased significantly in the first year of ART, then remained stable for years. HIV-1 DNA load base was the key factor associated with the decrease of HIV-1 DNA load, the lower the HIV-1 DNA load base, the lower HIV-1 DNA load. Therefore, earlier ART can contribute to the decrease of HIV-1 DNA load.

ABSTRACT

Background. Better integration of HIV and sexually transmitted infection (STI) prevention and treatment services is needed to accelerate progress towards the goal of zero new HIV infections. Objectives. To describe HIV positivity, antiretroviral therapy (ART) use, viral suppression and recency of HIV infection among symptomatic STI service attendees at two primary care clinics in South Africa. Methods. In a cross-sectional study, male and female STI service attendees presenting with symptoms consistent with STI syndromes were enrolled following informed consent. An interviewer-administered questionnaire was completed and appropriate genital and blood specimens were collected for STI testing and HIV biomarker measurements including recency of infection and antiretroviral (ARV) drug levels. Descriptive statistics were used to describe enrolled attendees, and to determine the proportion of attendees who were HIV-positive, recently infected, taking ART and virally suppressed. HIV-positive attendees with detectable ARVs were considered to be on ART, while those with viral loads (VLs) ≤200 copies/mL were considered virally suppressed. Results. Of 451 symptomatic attendees whose data were analysed, 93 (20.6%) were HIV-positive, with 15/93 (16.1%) being recently infected. Recent infection was independently associated with genital ulcer disease at presentation, especially ulcers with no detectable STI pathogens. Among the 78 (83.9%) with long-term infection, only 30 (38.5%) were on ART, with 23/30 (76.7%) virally suppressed. Conclusions. In a population at risk of HIV transmission, there was a high burden of recent infection and unsuppressed VLs. Incorporating pre-exposure prophylaxis, ART initiation and adherence support into STI services will be necessary for progress towards eliminating HIV transmission

ABSTRACT

Background: Only 66% of South African people living with HIV (PLWH) are virologically suppressed. Therefore, it is important to develop strategies to improve outcomes.Objectives: Assess the effect of interventions on 12-month retention in care and virological suppression in participants newly initiated on antiretroviral therapy.Method: Fifty-seven clinics were randomised into four arms: Ward-based primary health care outreach teams (WBPHCOTs); Game; WBPHCOT­Game in combination; and Control (standard of care). Sixteen clinics were excluded and four re-allocated because lay counsellors and operational team leaders failed to attend the required training. Seventeen clinics were excluded due to non-enrolment. Results: A total of 558 participants from Tshwane district were enrolled. After excluding ineligible participants, 467 participants were included in the analysis: WBPHCOTs (n = 72); Games (n = 126); WBPHCOT­Games (n = 85); and Control (n = 184). Retention in care at 12 months was evaluable in 340 participants (86.2%) were retained in care and 13.8% were lost to follow-up. The intervention groups had higher retention in care than the Control group, but this only reached statistical significance in the Games group (96.8% vs 77.8%; relative risk [RR] 1.25; 95% confidence interval [CI]: 1.13­1.38; P = 0.01). The 12 month virologic suppression rate was 75.3% and was similar across the four arms.Conclusion: This study demonstrated that an adherence game intervention could help keep PLWH in care.What this study adds: Evidence that interventions, especially Games, could improve retention in care

ABSTRACT

Background: The coronavirus disease 2019 (COVID-19) pandemic poses challenges to paediatric and adolescent HIV treatment programme. Modelling exercises raised concerns over potential impact of disruptions. Objectives: To describe the impact of the COVID-19 pandemic on viral load (VL) testing among infants, children and adolescents on antiretroviral treatment (ART) in Durban, South Africa. Method: Routinely collected, aggregated data of monthly VL counts done on all those less than 19 years old from January 2018 to January 2022 was analysed. An interrupted time series analysis using a Prais-Winsten linear regression model, including terms for lockdowns and excess mortality determined VL trends. Results: The unadjusted mean VL was 2166 (confidence interval [CI]: 252.2) and 2016 (CI: 241.9), P = 0.039, and percentage VL suppression rates (72.9%, CI: 2.4% vs 73.6%, CI: 1.8%) across COVID and pre-COVID periods, showing no significant difference, P = 0.262. In the interrupted time series analysis, modelled monthly VL counts did not differ significantly by lockdown level (e.g., level 5 lockdown: ­210.5 VLs, 95% CI: ­483.0 to +62.1, P = 0.138) or excess mortality (­0.1, 95% CI: ­6.3 to 6.1, P = 0.969). A significant downward trend in VL testing over time, including during the pre-COVID-19 period (­6.6 VL per month, 95% CI: ­10.4 to ­2.7, P = 0.002), was identified. Conclusion: Viral load suppression for children and adolescents were not negatively affected by COVID-19. A trend of decrease in VL testing predated COVID-19. What this study adds: Evidence presented that HIV VL testing and suppression rates in children and adolescents in a high burden setting were sustained through the COVID pandemic.

ABSTRACT

INTRODUCCIÓN: Se desconoce el grado de supresión viral en pacientes con infección por VIH que inician terapia antirretroviral (TAR) con cargas virales (CV) muy altas. OBJETIVO: Conocer el porcentaje de supresión viral en pacientes con VIH que inician TAR con CV ≥ 500.000 copias/mL a 96 semanas. PACIENTES Y MÉTODO: Estudio retrospectivo. Se incluyeron pacientes que iniciaron TAR con CV ≥ 500.000 copias/mL, entre los años 2008 y 2018, estratificándose en base a escala logarítmica. Se determinó el porcentaje de supresión viral, y las variables asociadas a este desenlace. RESULTADOS: Se incluyeron 221 pacientes. La mediana de edad y CV era de 43 años y 6,0 log, respectivamente, estando la mayoría (37%) en estadio C3 al inicio de TAR. El 48,8 y 87,7% de los pacientes logró la supresión viral al año y dos años de seguimiento, respectivamente. Se observó que, a mayor edad, a mayor inmunosupresión, y a mayor CV, mayor el tiempo para lograr la indetectabilidad. Sólo se demostró fracaso virológico en tres pacientes. DISCUSIÓN: Los pacientes con infección por VIH que inician TAR con CV muy altas demoran más tiempo en lograr la supresión viral, lo cual es proporcional a la magnitud de ésta y al grado de inmunosupresión, sin que esto conlleve mayor riesgo de fracaso virológico.


BACKGROUND: The degree of viral suppression in HIV patients who start antiretroviral therapy (ART) with very high viral loads (CV) is unknown. AIM: To know the percentage of viral suppression in HIV patients who start ART with CV ≥ 500,000 copies/mL at 96 weeks. METHOD: Retrospective study. Patients who started ART with a CV ≥ 500,000 copies/mL between 2008 and 2018 were included, stratifying on the basis of a logarithmic scale. The percentage of viral suppression and the variables associated with this outcome were determined. RESULTS: 221 patients were included. The median age and CV were 43 years and 6.0 log, respectively, with the majority (37%) being in stage C3 at the start of ART. 48.8 and 87.7% of the patients achieved viral suppression at one year and two years of follow-up, respectively. It was observed that the older the immunosuppression, and the higher CV, the longer the time to achieve undetectability. Virological failure was only demonstrated in three patients. DISCUSSION: Patients with HIV infection who start ART with very high CVs take longer to achieve viral suppression, which is proportional to the magnitude of this and the degree of immunosuppression, without this entailing a greater risk of virological failure.

ABSTRACT

Resumen Objetivo: Describir la supervivencia a siete años y los principales factores asociados a esta, en las personas con VIH que fueron atendidas en el sistema de salud colombiano entre 2011 a 2018. Métodos: Análisis de supervivencia de una cohorte de 64 039 personas diagnosticadas con VIH en Colombia. Se aplicó el método de Kaplan-Meier para estimar la probabilidad de supervivencia a partir de la fecha del diagnóstico. Se ajustó un modelo de supervivencia paramétrico flexible de Royston Parmar. Resultados: La estimación de la supervivencia global a 7 años fue de 94,8% (IC 95%: 94,5-95,2). El mayor riesgo de muerte se presentó en los hombres (HR: 1,2; IC 95%: 1,1-1,4; p: 0,010); en personas ≥50 años de edad (HR: 3,1; IC 95%: 1,6-6,3; p: 0,002); en el régimen subsidiado (HR: 2,2; IC 95%: 1,9-2,5; p: <0,001); en la etapa sida (HR: 2,8; IC 95%: 2,1-3,7; p: <0,001); en quienes presentaron la última carga viral detectable (HR: 7,1; IC 95%: 6,0-8,3; p: <0,001); y en quienes mostraron conteo de linfocitos T CD4+ <350 células/μL (HR: 1,9; IC 95%: 1,4-2,4; p: <0,001). Conclusión: La probabilidad de la supervivencia de las personas que viven con VIH aumenta al ser diagnosticados en edades jóvenes, en quienes presenten un recuento de linfocitos T CD4+ ≥350 células/μL, una carga viral indetectable (< 50 copias/mL) y no se encuentren en etapa sida.


Summary Objective: to describe the seven-year survival and predictors of mortality among people with HIV who were treated in the Colombian health system between 2011 and 2018. Methods: 64 039 people diagnosed with HIV in Colombia were included. Kaplan-Meier analysis estimated the probability of survival from the date of diagnosis. A Royston Parmar flexible parametric survival model was fitted. Results: The overall survival at 7 years was 94.8% (95% CI: 94.5-95.2). Survival was related to sex (men, HR: 1.2; 95% CI: 1.1-1.4; p: 0.010); people ≥50 years of age (HR: 3.1; 95% CI: 1.6-6.3; p: 0.002); subsidized regime (HR: 2.2; 95% CI: 1.9-2.5; p: <0.001); AIDS stage (HR: 2.8; 95% CI: 2.1-3.7; p: <0.001); a detectable viral load (HR: 7.1; 95% CI: 6.0-8.3; p: <0.001); and a CD4+ Lymphocyte count <350 cells/μL (HR: 1.9; 95% CI: 1.4-2.4; p: <0.001). Conclusion: The probability of survival of people living with HIV increases when they are diagnosed at a young age, in those with a CD4+ T Lymphocyte count ≥350 cells/μL, an undetectable viral load (<50 copies/mL) and are not in the AIDS stage.

ABSTRACT

Abstract Introduction: Cytomegalovirus (CMV) is one of the most common agents of infection in solid organ transplant patients, with significant morbidity and mortality. Objective: This study aimed to establish a threshold for initiation of preemptive treatment. In addition, the study compared the performance of antigenemia with qPCR results. Study design: This was a prospective cohort study conducted in 2017 in a single kidney transplant center in Brazil. Clinical validation was performed by comparing in-house qPCR results, against standard of care at that time (Pp65 CMV Antigenemia). ROC curve analysis was performed to determine the ideal threshold for initiation of preemptive therapy based on the qPCR test results. Results: Two hundred and thirty two samples from 30 patients were tested with both antigenemia and qPCR, from which 163 (70.26%) were concordant (Kappa coefficient: 0.435, p<0.001; Spearman correlation: 0.663). PCR allowed for early diagnoses. The median number of days for the first positive result was 50 (range, 24-105) for antigenemia and 42 (range, 24-74) for qPCR (p<0.001). ROC curve analysis revealed that at a threshold of 3,430 IU/mL (Log 3.54), qPCR had a sensitivity of 97.06% and a specificity of 74.24% (AUC 0.92617 ± 0.0185, p<0.001), in the prediction of 10 cells/105 leukocytes by antigenemia and physician's decision to treat. Conclusions: CMV Pp65 antigenemia and CMV qPCR showed fair agreement and a moderate correlation in this study. The in-house qPCR was revealed to be an accurate method to determine CMV DNAemia in kidney transplant patients, resulting in positive results weeks before antigenemia.


Resumo Introdução: Citomegalovírus (CMV) é um dos agentes infecciosos mais comuns em pacientes com transplante de órgãos sólidos, com morbidade e mortalidade significativas. Objetivo: Este estudo visou estabelecer um limite para o início do tratamento preemptivo. Além disso, comparou o desempenho da antigenemia com os resultados da qPCR in house. Desenho do estudo: Este foi um estudo de coorte prospectivo realizado em 2017 em um centro único de transplante renal no Brasil. A validação clínica foi realizada comparando resultados de qPCR in house, com o padrão de atendimento na época (Antigenemia para CMV Pp65). A análise da curva ROC foi realizada para determinar o limite ideal para o início da terapia preemptiva baseado nos resultados do teste qPCR in house. Resultados: 232 amostras de 30 pacientes foram testadas com antigenemia e qPCR, das quais 163 (70,26%) foram concordantes (Coeficiente Kappa: 0,435, p<0,001; Correlação Spearman: 0,663). PCR permitiu diagnósticos precoces. O número médio de dias para o primeiro resultado positivo foi 50 (intervalo, 24-105) para antigenemia e 42 (intervalo, 24-74) para qPCR (p<0,001). A análise da curva ROC revelou que em um limite de 3.430 UI/mL (Log 3,54), qPCR teve sensibilidade de 97,06% e especificidade de 74,24% (AUC 0,92617 ± 0,0185, p<0,001), na previsão de 10 células/10(5) leucócitos por antigenemia e na decisão do médico de tratar. Conclusões: Antigenemia para CMV Pp65 e qPCR para CMV mostraram uma concordância aceitável e uma correlação moderada neste estudo. qPCR in house revelou-se um método preciso para determinar DNAemia do CMV em pacientes transplantados renais, obtendo resultados positivos semanas antes da antigenemia.

ABSTRACT

Abstract Aim: To assess the epidemiological situation of people living with HIV and AIDS (PLWHA) in the municipalities and regions of Colombia in 2018. Materials and methods: A cross-sectional study was conducted with secondary data from the High-Cost Diseases Fund from February 1st, 2018 to January 31st, 2019. We included sociodemographic, clinical variables, and related to geographic location. We calculated incidence, prevalence, and mortality according to the Colombian geographical regions, department and municipality of residence. Crude and age-standardized rates were estimated. Results: By 2018, 10,930 new cases of PLWHA were reported, being more frequent in males, aged between 25 to 49 years. 39.32% were reported with AIDS and 35.27% had undetectable HIV viral load. During 2018, there are 109,056 PLWHA in Colombia. The highest age-standardized incidence and prevalence were reported in Florencia (Cauca) (354.28 per 100,000 and 3.32 per 100people, respectively). The age-standardized incidence rate was 22.12 per 100,000 population (95% CI 21.71-22.54). Age-standardized prevalence and mortality were 0.23 per 100 population (95% CI 0.22-0.23) and 3.78 per 100,000 population (95% CI 3.61-3.96), respectively. Conclusion: Different strategies should be implemented to improve the identification of risk factors in the population, especially in some regions of Colombia and prevent transmission.

ABSTRACT

Introducción: Se estima que en Argentina son 129 mil las personas que poseen el virus de inmunodeficiencia humana, aunque un 20% de ellas lo desconoce. El 20% de 5800 nuevos casos por año en el país corresponden a CABA. No hay datos sobre la situación de pacientes que se atienden en hospitales públicos de CABA con respecto a objetivos de la OMS. Objetivo: Analizar esquemas antirretrovirales y situación virológica e inmunológica de las personas con VIH (PcVIH) en TAR que se asisten hospitales públicos de CABA. Métodos: Estudio descriptivo y retrospectivo, bajo muestreo por conveniencia. Análisis de datos obtenidos del Sistema de Administración de Pacientes VIH (SVIH), activos a junio de 2018. Es dable aclarar que la primera parte se refiere a la fuente de información, y que sean activos a junio de 2018 se refiere a criterio de inclusión y periodo de análisis respectivamente. Variables analizadas: sexo, edad, distribución de TAR, CV y CD4 utilizando el programa SPSS 20. Resultados: 6878 PcVIH en TAR, 66,6% hombres. 79% con al menos 1 CV. De ellas, con CV indetectables (<40 copias) 62% (78% del total de PcVIH con CV). Datos de CD4 en 56% PcVIH: 65% con >500. En primera línea de TAR 88,3%: 42% IP potenciados, 45% INNTI, 13% INSTI. De CV indetectables (<40 copias), 92% en primera línea de TAR (significativo) y de las detectables, 80%. INNTI como tercera droga, significativo para CV indetectable (<40 copias). 45% de PcVIH en TAR sin CV y/o CD4. Discusión: La muestra representa la mitad de las PcV1 de CABA atendidas en el sistema público. Más de la mitad de la población estudiada se encuentra indetectable (<40 copias). INNTI siguen siendo las terceras drogas más utilizadas. Alto % de PcVIH en TAR sin CV y/o CD4. Insuficientes laboratorios (CV y CD4), baja disponibilidad de datos y lejanía del objetivo de OMS indican deficiencias del sistema de salud. Mejoras en acceso a TAR, a determinaciones de laboratorio, y en la calidad de los datos son necesarios.


Introduction: HIV infection is significant in Buenos Aires City. 20% of 5800 new cases/year in the country are from this region. There ́s no data about PLwHIV treated in public hospitals of Buenos Aires City about WHO objectivesObjetives: To know and analyze the situation PLwHIV treated in p ublic hospitals of Buenos Aires City about treatment, and virological and immunological responses.Methods: Descriptive and retrospective study. Data obtained from the Administration System of HIV Patients actives in June 2018. Variables analyzed: gender, age, ART distribution, VL and CD4 counts, with SPSS 20 ProgramResults: 6878 PLwHIV on ART, 66,6% male. 79% with at least 1 VL. Of them, 62% with undetectable VL (78% of all PLwHIV with VL). CD4 data in 56% PLwHIV: 65% >500: In 1st line of TAR 88,3%: 42% boosted IPs, 45% NNRTIs, 13% INIs. Of PLwHIV with undetectable VL, 92% in 1st line of ART (significant). NNRTIs significant for undetectable VL.Discussion:Our cohort represents 50% de los PLwHIV of Buenos Aires City. 62% currently with undetectable VL. NNRTIs still the more used 3rd antiretroviral. High % of PLwHIV on ART without VL and/or CD4 count. Not enough laboratory determinations (VLs and CD4 counts), low data ava ilability and remoteness of WHO ́s goals for 2020, show health system ́s weakness. Improvements in Access to ART and laboratory determinations and in the data availability andquality are necessary.

ABSTRACT

INTRODUCCIÓN: La medición de carga viral (CV) de virus hepatitis B (VHB) y C (VHC) es fundamental en el seguimiento de pacientes con terapia antiviral. La metodología más utilizada para su determinación es COBAS ®-TaqMan ®. Recientemente, se desarrolló la tecnología Xpert ®, que se debe evaluar. OBJETIVO: Comparar la medición de la CV de VHB y VHC por metodología Xpert® con COBAS®-TaqMan® como método de referencia. MATERIAL Y MÉTODOS: 39 muestras de suero de pacientes con VHB y 39 con VHC, previamente cuantificadas por COBAS ®-TaqMan ®, fueron analizadas mediante Xpert® y los resultados se compararon utilizando la regresión de Deming y gráfico Bland-Altman. RESULTADOS: Hubo una alta correlación entre Xpert® y COBAS®-TaqMan®. Para VHB, la ecuación de Deming fue XpertHBV = 0,44 + 0,99xCOBASTaqManHBV, con coeficiente de correlación de 0,94 y diferencia entre medias de -0,401 log10 (IC95%: -1,985 a 1,183). Para VHC, la ecuación de Deming fue XpertHCV = 0,36 + 0,87x COBASTaqManHCV, con coeficiente de correlación de 0,98 y diferencia entre medias de 0,328 log (IC95%: -0,449 a 1,105). CONCLUSIÓN: El nuevo sistema Xpert® muestra una buena correlación con COBAS ®-TaqMan ® para la medición de la CV de VHB y VHC, siendo una buena alternativa para el seguimiento de pacientes en tratamiento.


BACKGROUND: The measurement of viral load (VL) of hepatitis B (HBV) and C (HCV) viruses is essential in the follow-up of patients with antiviral therapy. The most widely used methodology for this determination is COBAS®-TaqMan®. Recently, the Xpert® technology was developed and needs to be evaluated. AIM: To compare the measurement of the VL of HBV and HCV by Xpert® methodology with COBAS®-TaqMan® as a reference method. MATERIAL AND METHODS: 39 serum samples from patients with HBV and 39 with HCV, previously quantified by COBAS®-TaqMan®, were analyzed using Xpert® and the results were compared using Deming regression and Bland-Altman plot. RESULTS: There was a high correlation between Xpert® and COBAS®-TaqMan®. For HBV, the Deming equation was XpertHBV = 0.44 + 0.99xCOBASTaqManHBV, with a correlation coefficient of 0.94 and a difference between means of -0.401 log (95% CI: -1.985 to 1.183). For HCV, the Deming equation was XpertHCV = 0.36 + 0.87x COBASTaqManHCV, with a correlation coefficient of 0.98 and a difference between means of0.328 log10 (95% CI: -0.449 to 1.105). CONCLUSION: The new Xpert® system shows a good correlation with COBAS®-TaqMan® for the measurement of the VL of HBV and HCV, being a good alternative for the follow-up of patients under treatment.

ABSTRACT

Abstract Objective: To evaluate the relationship between tobacco use and viral load and CD4+ T cell count in HIV patients. Results: The research conducted was a descriptive study of 317 patients on highly active antiretroviral therapy (HAART), 18 years old and above, who attended the "Unidad de Atención Integral" (UAI) at the Hospital Regional Universitario José María Cabral y Báez, in Santiago, Dominican Republic. Of those 317 patients, 172 were included in the data analysis. It was found that a 77.3% of smokers had a CD4+ T cell count equal to or below 250 cells/mm3. 75% of smokers had a viral load equal to or greater than 400 copies/ml. In addition, 82.9% of nonsmokers presented with a viral load below 400 copies/ml. The smokers were more likely to have a viral load equal to or greater than 400 copies/ml (OR = 6.285, P < 0.001), in comparison with nonsmokers. Patients younger than 45 years old were more likely to have a viral load equal to or above 400 copies/ml compared to older patients (OR = 3.313, P = 0.024).


Resumen Objetivo: Evaluar la relación entre el consumo de tabaco, la carga viral y el recuento de linfocitos T CD4+ en pacientes con VIH. Resultados: La investigación fue realizada mediante un estudio descriptivo a 317 pacientes en terapia antirretroviral de alta actividad (TARGA), de 18 años o ma yores, que asistían a la Unidad de Atención Integral (UAI) del Hospital Regional Universitario José María Cabral y Báez, en Santiago, República Dominicana. De esos 317 pacientes, 172 se incluyeron en el análisis de datos. Se encontró que un 77,3% de los fumadores tenían un recuento de células T CD4 + igual o inferior a 250 células / mm3. El 75% de los fumadores tenían una carga viral igual o superior a 400 copias / ml. Además, el 82,9% de los no fumadores presentaba una carga viral inferior a 400 copias / ml. Los fumadores tenían más probabilidades de tener una carga viral igual o superior a 400 copias / ml (OR = 6.285, P <0.001), en comparación con los no fumadores. Los pacientes menores de 45 años tenían más probabilidades de tener una carga viral igual o superior a 400 copias / ml en comparación con los pacientes mayores (OR = 3,313, P = 0,024).

ABSTRACT

La actual pandemia de COVID-19 provocada por el virus SARS-CoV-2 es un problema de salud que afecta a la población globalmente. Su desarrollo puede ser asintomático o exhibir manifestaciones clínicas moderadas o severas dependiendo en gran medida de la respuesta inmune de quien la padece. Esta enfermedad afecta principalmente a los pulmones a través del desarrollo del síndrome respiratorio agudo severo (SRAS), tanto como por la «tormenta de citocinas¼, una respuesta inflamatoria exacerbada que podría provocar una falla multisistémica y, en casos severos, la muerte. Se conoce que la enzima convertidora de angiotensina 2 (ECA-2), presente en diversos tejidos del cuerpo, actúa como receptor funcional del virus SARS-CoV-2 facilitando la entrada de éste a las células. Se ha demostrado la presencia de dicho receptor en varios tejidos orales, por lo que se puede considerar a la cavidad bucal como una vía latente de infección por dicho coronavirus, ya que su mecanismo de transmisión es a través de la inhalación de partículas virales, ya sea por vía nasal u oral. Así mismo, la presencia de carga vírica en la saliva y algunos de los síntomas de la COVID-19, por ejemplo la ageusia, pueden indicar la presencia de contagio viral en etapas tempranas. La presente revisión muestra evidencia que sugiere que diversos tejidos en la cavidad oral podrían ser considerados sitios potenciales de contagio por el SARS-CoV-2, teniendo un papel importante en el mecanismo de transmisión y en el desarrollo de coinfecciones (AU)


The COVID-19 pandemic caused by the SARS-CoV-2 virus is currently a global healthcare problem. The onset of this disease can exhibit several clinical manifestations ranging from mild to severe symptoms, depending on the individual's immune response. COVID-19 primarily affects the lungs by developing the Severe Acute Respiratory Syndrome (SARS) and the «cytokine storm¼, an exacerbated inflammatory reaction that can lead to multiorgan failure and consequently death. The angiotensin-converting enzyme 2 (ACE-2), present in several tissues in the human body, is known to act as the functional receptor of the SARS-CoV-2 germ facilitating its entrance into the cells. Such receptor is also present in diverse oral cavity tissues, indicating a latent route of infection due to its influence in the transmission mechanism by inhalation, either oral or nasal, of virus particles. Also, viral load in saliva and taste disorder symptoms like ageusia could indicate a viral infection in its early stages. This article presents evidence suggesting that several tissues in the oral cavity can be considered potential sites of SARS-CoV-2 infection, thus playing an essential role in the transmission mechanism and development of co-infections (AU)

ABSTRACT

ABSTRACT BACKGROUND: High prevalence of human immunodeficiency virus (HIV) infection and occurrence of drug-resistant strains have been recorded in northern Brazil. Abandonment of treatment and insufficient and inadequate adherence to antiretroviral therapy (ART) among people living with HIV/AIDS (PLWHA) have been recorded in the metropolitan area of Belém, the capital of the state of Pará. OBJECTIVES: To identify the sociodemographic profile and level of adherence to ART among women seen at a referral unit in the interior of Pará, northern Brazil. DESIGN AND SETTING: Cross-sectional study at a referral unit for care for PLWHA. METHODS: We included 86 women living with HIV/AIDS (WLWHA) in the Rio Caeté integrated region, northeastern Pará. Social, demographic and behavioral information, as well as the ART level, were obtained using forms that have been described in the scientific literature. Logistic regression models were used to assess associations of variables with ART. RESULTS: Most WLWHA were single (52.4%), young (47.7%) and heterosexual (97.7%), had low levels of education (63.0%), were unemployed (69.8%), had one sexual partner (75.7%), used condoms (46.7%) and were not using either licit drugs (68.7%) or illicit drugs (89.6%). Their adherence level was classified as insufficient , and only their viral load showed an association with ART. CONCLUSIONS: The participants' low level of education and poor socioeconomic conditions may have been interfering with their adherence to ART. Such influences can be minimized through multiprofessional interventions that take the individuality of women served by the healthcare service into consideration.

ABSTRACT

INTRODUCTION: The city of Santarém, the regional healthcare center in the western Pará State, lacks studies on the epidemic of the human immunodeficiency virus (HIV), in particular, on the causes of death. OBJECTIVE: To characterize the sociodemographic and clinical profile related to the evolution of HIV infection to death. METHODS: The sample consisted of 94 medical records of patients from a reference center in the city of Santarém-PA, who died between 2010-2018. Data were collected on the sociodemographic profile, immunological and clinical characteristics of the patients. Data were analyzed using descriptive and inferential statistics, adopting p<0.05. RESULTS: Most deaths were male (67%), aged between 15-29 years (39%) and diagnosed between 30-44 years (41%), single (54%), mixed race (91.5%), from Santarém (77%) and with sexual intercourse being the main type of exposure (95.7%). Most patients were not being treated at the moment of death (56.4%), the main cause of death was respiratory failure (5%), in which, these individuals had, at the moment of death, TCD4+ lymphocytes <200 cell/mm3 (26%) and detectable viral load (29%). CONCLUSION: The lifetime from diagnosis to death was 48.45±50,30 months, and immunosuppression in the diagnosis was positively associated with the shortest survival time. However, sex was not associated with the immunological profile, age at the time of diagnosis, and death. There was only a tendency for women towards immunosuppression and detectable viral load.


INTRODUÇÃO: A cidade de Santarém, o polo assistencial da região oeste do Pará, carece de estudos sobre a epidemia do vírus da imunodeficiência humana (HIV), especialmente, sobre as causas de óbitos. OBJETIVO: Caracterizar o perfil sociodemográfico e clínico relacionado à evolução da infecção pelo HIV até a morte. MÉTODO: A amostra foi de 94 prontuários de pacientes de um centro de referência do município de Santarém-PA, que evoluíram a óbito entre os anos de 2010-2018. Foram levantados os dados sobre o perfil sociodemográfico, características imunológicas e clínicas dos pacientes. Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. RESULTADOS: A maioria dos óbitos foi de indivíduos do sexo masculino (67%), com faixa etária do diagnóstico entre 15-29 anos (39%) e de falecimento entre 30-44 anos (41%), solteiros (54%), pardos (91,5%), procedentes de Santarém (77%) e com a relação sexual sendo o principal tipo de exposição (95,7%). A maioria dos pacientes não estava em tratamento no momento do óbito (56,4%), a principal causa de morte foi por insuficiência respiratória (5%), no qual, esses indivíduos apresentavam, no momento da morte, linfócitos TCD4+ <200 cél/mm3 (26%) e carga viral detectável (29%). CONCLUSÃO: O tempo de vida do diagnóstico ao óbito foi de 48,45±50,30 meses e a presença de imunossupressão no diagnóstico associou-se positivamente com o menor tempo de sobrevida. Contudo, o sexo não apresentou associação com o perfil imunológico, a idade no momento do diagnóstico e do óbito, apenas notou-se uma tendência das mulheres para a imunossupressão e carga viral detectável.
