RESUMO

Introducción: En el síndrome de inmunodeficiencia adquirida las neoplasias han jugado un papel preponderante, y con el advenimiento del tratamiento antirretroviral (TAR), la infección por VIH se ha transformado en una enfermedad crónica, siendo los tumores malignos una causa importante de morbilidad y mortalidad. Objetivo: Describir las características demográficas, clínicas y de laboratorio de las personas que viven con VIH (PVVIH) y han sido diagnosticadas con cáncer en Colombia y comparar los grupos de neoplasias definitorias y no definitorias de Sida. Métodos: Revisión multicéntrica retrospectiva, en la que se recolectó y analizó datos relacionados con la infección por VIH y de diagnóstico de cáncer y tipo. Incluyó PVVIH diagnosticadas con neoplasias malignas atendidas en 23 centros de atención de pacientes con VIH en 11 ciudades de Colombia desde 1986 hasta 2018. Resultados: En 23.189 pacientes, se identificaron 650 casos de malignidad (prevalencia de 2,8 % [IC de 95%: 2,6-2,9]). La neoplasia definitoria de Sida (NDS) sigue siendo el tipo de cáncer prevalente (71,1%), las neoplasias malignas más frecuentes fueron sarcoma de Kaposi (n: 330; 50,8%), linfoma no Hodgkin (n: 110; 16,9%), cáncer de piel (n: 48; 7,4%) y linfoma de Hodgkin (n: 25; 3,8%). Los pacientes con NDS tenían más probabilidades de ser HSH y estar en un estadio CDC 3, un recuento de linfocitos T CD4 < 200/μL y una carga viral del VIH ≥ 50 copias/mL al momento del diagnóstico de malignidad. Las personas con neoplasias no definitorias de Sida (NNDS) eran significativamente mayores y tenían más probabilidades de ser fumadores. Conclusiones: Estos hallazgos son relevantes considerando la creciente carga de cáncer en las PVVIH que envejecen y las causas cambiantes de morbilidad y mortalidad. La presentación tardía a la atención del VIH y el retraso en el inicio del TAR son probablemente factores que contribuyen al cambio más lento hacia NNDS en comparación con las regiones de altos ingresos donde hay un acceso más rápido y temprano al TAR. El conocimiento de las tendencias epidemiológicas actuales y el perfil del cáncer en las PVVIH es fundamental para mejorar los esfuerzos de prevención y tratamiento del cáncer en el contexto de la atención integral del VIH.


Background: In the acquired immunodeficiency syndrome, neoplasms have played a preponderant role, and with the advent of antiretroviral treatment (ART), HIV has become a chronic disease, with malignant tumors being an important cause of morbidity and mortality. Aim: To describe the demographic, clinical, and laboratory characteristics of people living with HIV (PLHIV) who have been diagnosed with cancer in Colombia and to compare the groups of AIDS-defining (ADC) and non-AIDS-defining neoplasms (NADC). Methods: Retrospective, multicenter study that included people living with HIV/AIDS (PLHIV) diagnosed with malignancies treated at 23 HIV care centers located in 11 Colombian cities from 1986 to 2018. Data related to HIV infection and cancer diagnosis were collected and analyzed. Results: Among 23,189 patients, 650 malignancy cases were identified (prevalence of 2.8% [95% CI 2.6-2.9]). AIDS-defining neoplasm remains the most prevalent type of cancer (71.1%), The most frequent individual malignancies were Kaposi sarcoma (n: 330; 50.8%), non-Hodgkin lymphoma (n: 110; 16.9%), skin cancer (n: 48; 7.4%), and Hodgkin lymphoma (n: 25; 3.8%). Compared people with NADC, with ADC were more likely to be MSM and have a CDC HIV stage 3, CD4 T cell count < 200/μL, and HIV viral load ≥ 50 copies/mL at the time of malignancy diagnosis. PLHIV and with NADC were significantly older and were more likely to be smokers. Conclusions: These findings are relevant considering the increasing burden of cancer in the aging PLHIV and the changing causes of morbidity and mortality. Late presentation to HIV care and delayed ART initiation are likely factors contributing to the slower shift toward NADCs compared with high-income regions where access to ART is better. Knowledge of the current epidemiological trends and profile of cancer in PLWHA is critical to improve cancer prevention and treatment efforts in the context of comprehensive HIV care.

RESUMO

INTRODUCTION: HIV is an independent risk factor for cardiovascular diseases (CVD). There is insufficient information regarding comorbidities and cardiovascular risk factors in the Colombian HIV population. The aim of this study is to describe the prevalence of cardiovascular risk factors and comorbidities in patients from the HIV Colombian Group VIHCOL. METHODS: This is a multicenter, cross-sectional study conducted in the VIHCOL network in Colombia. Patients 18 years or older who had at least 6 months of follow-up were included. A stratified random sampling was performed to estimate the adjusted prevalence of cardiovascular risk factors and comorbidities. RESULTS: A total of 1616 patients were included. 83.2% were men, and the median age was 34 years. The adjusted prevalence for dyslipidemia, active tobacco use, hypothyroidism, and arterial hypertension was 51.2% (99% CI: 48.0%-54.4%), 7.6% (99% CI: 5.9%-9.3%), 7.4% (99% CI: 5.7%-9.1%), and 6.3% (99% CI: 4.8%-7.9%), respectively. CONCLUSIONS: In this Colombian HIV cohort, there is a high prevalence of modifiable CVD risk factors such as dyslipidemia and active smoking. Non-pharmacological and pharmacological measures for the prevention and management of these risk factors should be reinforced.

RESUMO

BACKGROUND: Few studies have used implementation science frameworks to identify determinants of PrEP prescription by healthcare providers. In this work, we developed and psychometrically examined a questionnaire using the theoretical domains framework (TDF) and the consolidated framework for implementation research (CFIR). We used this questionnaire to investigate what factors influence the intention of healthcare providers to offer PrEP care and advocate for PrEP. METHODS: We conducted a cross-sectional study in 16 HIV healthcare organizations in Colombia. A 98-item questionnaire was administered online to 129 healthcare professionals. One hundred had complete data for this analysis. We used exploratory factor analysis to assess the psychometric properties of both frameworks, and multinomial regression analysis to evaluate the associations of the frameworks' domains with two outcomes: (1) intention to offer PrEP care and (2) intention to advocate for PrEP impmentation. RESULTS: We found support for nine indices with good internal consistency, reflecting PrEP characteristics, attitudes towards population needs, concerns about the use of PrEP, concerns about the role of the healthcare systems, knowledge, beliefs about capabilities, professional role, social influence, and beliefs about consequences. Notably, only 57% of the participants were likely to have a plan to care for people in PrEP and 66.7% were likely to advocate for PrEP. The perception of the need for PrEP in populations, the value of PrEP as a practice, the influence of colleagues, and seeing PrEP care as a priority was related to being less likely to be unwilling to provide or advocate for PrEP care. CONCLUSION: Our findings suggested the importance of multilevel strategies to increase the provision of PrEP care by healthcare providers including adquisition of new skills, training of PrEP champions, and strength the capacity of the health system.

RESUMO

Interventions addressing the sexual health need of HIV-positive men who have sex with men (MSM) in Latin America are scarce. We adapted and evaluated GPS, a group-based intervention led by peers, developed using the Information-Motivation-Behavioral (IMB) model and motivational interviewing (MI). We used McKleroy et al framework to culturally adapt GPS to MSM living with HIV infection in Colombia. Then, a one-armed pilot trial examined changes in depressive symptoms, loneliness, self-efficacy for engaging in sexual risk reduction behaviors, sexual sensation seeking and sexual compulsivity at pre-intervention, post-intervention, and 3-month follow-up. These results were complemented with semistructured interviews with participants 3 months after the intervention. GPS was identified to be culturally acceptable with few changes in materials and exercises. Facilitators showed high levels of adherence and fidelity to MI principles. Seven of 11 eligible participants finished the intervention; GPS positively influenced self-efficacy for condom negotiation, depressive symptoms, and condomless anal sex with partners of unknown HIV status. Exit interviews revealed that GPS was well-designed, relevant, facilitated discussion of sex in a nonjudgmental manner, and helped make positive changes in participants' sexual lives. These results provided preliminary evidence of an intervention to address sexual and mental health of MSM living with HIV in Latin America.

RESUMO

Introduction: HIV-related stigma is detrimental to people living with HIV (PLH), and reducing it is essential for achieving an HIV/AIDS-free generation. Abbreviated stigma scales can improve the feasibility of surveys that broadly explore factors affecting PLH. This study tested the psychometric properties of a Spanish translation of the abbreviated 10-item Berger's HIV stigma scale. Methods:We recruited a sample of 105 PLH regularly attending a specialized clinic in Cali, Colombia. English-to-Spanish and Spanish-to-English back translation was performed of the Berger's 10-item HIV stigma scale.Exploratory and confirmatory factor analyses were carried out to assess its validity. Pre- and post-test reliability (15 days) was estimated with the intra-class correlation coefficient (ICC). Results: The Confirmatory Factor Analysis (CFA) was used to confirm a two-factor solution with three poor items removed, resulting in a 7-item HIV Stigma Scale. The resulting 7-item HIV stigma scale had a Cronbach's alpha of 0.73 with an ICC of 0.83 (CI 95%: 0.75­0.89). One factor loaded three items related to negative self-image (internalised stigma), and the other four items were related to personalized (enacted) HIV stigma. Both factors were related to depression and adherence to antiretroviral therapy. Conclusion: The Spanish translation of the 10-item HIV stigma scale did not perform well due to problems in items 4, 5, and 6. Rather, a modified 7-item version had a good fit with a two-factor loading in which both HIV stigma factors correlated significantly with depression and HIV medication adherence.


Introducción: el estigma asociado al VIH atenta contra la salud de las personas que viven con VIH (PVV), así que reducirlo es esencial para erradicar el VIH/SIDA. Las escalas abreviadas para estigma pueden facilitar la ejecución de encuestas amplias sobre factores que afectan a las PVV. Este estudio examinó las propiedades psicométricas de una traducción al español de la escala de Berger de 10 ítems. Métodos: se reclutaron 105 PVV en una clínica de VIH en Cali, Colombia. La escala de Berger de 10 ítems se tradujo del inglés al español y después del español al inglés. La validez de constructo se evaluó con análisis factoriales (exploratorios/confirmatorios). La confiabilidad pre y postest (15 días) se estimó con el coeficiente de correlación intraclase (CCI). Resultados: el análisis factorial confirmó una solución de dos factores carente de tres ítems de pobre desempeño, resultando en una escala final de siete ítems, la cual tuvo un coeficiente alfa de Cronbach de 0,73 y un CCI de 0,83 (IC 95%: 0,75-0,89). Un factor cargó tres ítems relacionados con autoimagen negativa (estigma internalizado), y otros cuatro ítems relacionados con el estigma personalizado (estigma declarado/ejercido por terceros). Ambos factores estuvieron asociados a depresión y baja adherencia a tratamiento antirretroviral. Conclusión: la escala de 10 ítems en español para estigma asociado al VIH tuvo pobre desempeño por problemas con los ítems 4, 5 y 6. En cambio, una versión modificada de siete ítems tuvo mejor desempeño, cargando dos factores correlacionados significativamente con depresión y adherencia al tratamiento antirretroviral.

RESUMO

INTRODUCTION: Men who have sex with men (MSM) and transgender women (TW) in Colombia are highly affected by HIV. To improve understanding of the role of HIV risk behaviors in HIV acquisition, we used the syndemic framework, a useful concept to inform prevention efforts. OBJECTIVE: To examine the effect of four psychosocial conditions, namely, forced sex, history of childhood sexual abuse, frequent alcohol use, and illicit drug use on unprotected sex and the synergistic effects ("syndemic" effects) of these conditions on HIV risk behavior. MATERIALS AND METHODS: We enrolled a total of 812 males (54.7% men who have sex with men, MSM; 7.3% transgender women, and 38% non-MSM). The participants were recruited from neighborhoods of low socioeconomic status through free HIV-counseling and -testing campaigns. We performed Poisson regression analysis to test the associations and interactions between the four psychosocial conditions and unprotected sex with regular, occasional, and transactional partners. To test the "syndemic" model, we assessed additive and multiplicative interactions. RESULTS: The prevalence of any psychosocial condition was 94.9% in transgender women, 60.1% in MSM, and 72.2% in non-MSM. A higher likelihood of transactional sex was associated in MSM (prevalence ratio (PR)=7.41, p<0.001) and non-MSM (PR=2.18, p< 0.001) with three or all four conditions compared to those with one condition. Additive interactions were present for all combinations of psychosocial problems on transactional sex n MSM. No cumulative effect or additive interaction was observed in transgender women. CONCLUSIONS: Our study highlights the need for bundled mental health programs addressing childhood sexual abuse, illicit drug use, and frequent alcohol use with other HIV prevention programs.


Introducción. Los hombres que tienen sexo con hombres (HSH), y las mujeres transgenero (MT) en Colombia continuan estando a mayor riesgo de VIH. Para entender como los comportamientos se asocian al VIH, se uso la teoria de la sindemia, la cual se ha considerado muy útil en el desarrollo de estrategias de prevención. Objetivo. Examinar el efecto de cuatro afecciones psicosociales, a saber: historia de sexo forzado, historia de abuso sexual infantil, consumo frecuente de alcohol y consumo de drogas ilícitas en las relaciones sexuales sin protección, así como los efectos sinérgicos (efectos "sindémicos") de estas afecciones sobre el comportamiento de riesgo para HIV. Materiales y métodos. Se hizo un estudio transversal que incluyó 812 participantes (hombres que tienen sexo con hombres, HSH: 54,7 %; mujeres transgénero: 7,3 % y hombres que no tenían sexo con otros hombres: 38 %). Los participantes se reclutaron en barrios de estratos socioeconómicos bajos a través de campañas gratuitas de asesoramiento y pruebas de HIV. Se hizo un análisis de regresión de Poisson para probar las asociaciones e interacciones entre las cuatro condiciones psicosociales y las relaciones sexuales sin protección con parejas regulares, ocasionales y comerciales. Para probar el modelo "sindémico" se evaluaron las interacciones aditivas y multiplicativas. Resultados. La prevalencia de cualquiera de las condiciones psicosociales fue de 94,9 % en mujeres transexuales, de 60,1 % en HSH y de 72,2 % en hombres que no tienen sexo con hombres. Se encontró una mayor probabilidad de tener sexo comercial en los HSH (razón de prevalencia (RP)=7,41, p<0,001) y en los que no tienen sexo con otros hombres (RP=2.18, p<0,001) con tres de las condiciones psicosociales, o con las cuatro, en comparación con aquellos con una sola condición. Las interacciones aditivas se registraron entre todas las combinaciones de problemas psicosociales con el sexo comercial en los HSH. No se observó un efecto acumulativo ni interacciones en mujeres transexuales. Conclusiones. El estudio resalta la necesidad de combinar programas de salud mental que aborden el abuso sexual infantil, el abuso de drogas y el consumo frecuente de alcohol con otros programas de prevención del HIV.

RESUMO

Objective:To determine HIV presence and risk behaviors ofpersons of low socio-economic status in the city of Popayan-Colombia.Methods:Cross-sectional study; between 2008 and 2009, 363participants of Popayan signed informed consent and receivedpre and post HIV test counseling. Socio-demographic charac-teristics and history of STDs, risk behaviors and previous HIVtesting were assessed. Descriptive statistics, correlations andmultivariate logistic regression were calculatedResults:Mean age 33,5±10,2; 66 percentwomen. Frequency of HIV-positive patients was 3.86 percent (95 percentCI: 1.87-5.85), greater inmen (7.38 percent; p=0,013). Greater frequency of HIV-positive pa-tients was observed in people age 29-37, those without a stablepartner, and those with history of risky alcohol consumption(more than five drinks in 2 hours) .Conclusions:HIV-positive patients frequency in this popu-lation was greater than national estimate for general popula-tion, aged 15-49 in Colombia, with even greater frequency inmen. This study suggests that characteristics associated withlow socioeconomic status, in economically active population,without a stable partner and with risky alcohol use, can poten-tially increase risk of HIV infection.

METHODS: Cross-sectional study; between 2008 and 2009, 363 participants of Popayan signed informed consent and received pre and post HIV test counseling. Socio-demographic characteristics and history of STDs, risk behaviors and previous HIV testing were assessed. Descriptive statistics, correlations and multivariate logistic regression were calculated. RESULTS: Mean age 33.5±10,2; 66 %women. Frequency of HIV-positive patients was 3.86 % (95% CI:1.87-5.85), greater in men (7.38%; p= 0.013). Greater frequency of HIV-positive patients was observed in people age 29-37, those without a stable partner, and those with history of risky alcohol consumption (more than five drinks in 2 h). CONCLUSIONS: HIV-positive patients frequency in this population was greater than national estimate for general population, aged 15-49 in Colombia, with even greater frequency in men. This study suggests that characteristics associated with low socioeconomic status, in economically active population, without a stable partner and with risky alcohol use, can potentially increase risk of HIV infection.


OBJETIVOS: Determinar la frecuencia de VIH y comportamientos de personas en contexto de vulnerabilidad por estrato socioeconómico bajo de la ciudad de Popayán-Colombia. MÉTODOS: Estudio transversal; entre 2008 y 2009, 363 participantes de Popayán dieron su consentimiento informado y recibieron consejería previa y posterior a la prueba del VIH. Se evaluaron características socio-demográficas, antecedentes de enfermedades de transmisión sexual, comportamientos y prueba previa del VIH. Se calcularon estadísticas descriptivas, correlaciones y regresión logística multivariada. RESULTADOS: La edad promedio 33.5 ± 10.2; 66% mujeres. La frecuencia de pacientes VIH positivo fue 3.86% (IC95: 1.87-5 .85), mayor en hombres (7.38%, p= 0.013). Personas de 29-37 años de edad, sin una pareja estable y aquellos con historia de consumir más de cinco copas de licor en dos horas seguidas presentaron mayor frecuencia de pacientes VIH positivo. CONCLUSIONES: La positividad para VIH en esta población es mayor que el estimado nacional para población general en edad 15-49, con frecuencia aún mayor en hombres. Los datos sugieren que la vulnerabilidad asociada con un estrato socioeconómico bajo en la población económicamente activa, sin una pareja estable y con consumo riesgoso de alcohol, puede aumentar potencialmente el riesgo de infección por el VIH.

RESUMO

Cuando los trabajadores de la salud o las personas con escasos conocimientos de bioestadística se involucran en investigaciones, especialmente de tipo cuantitativo, aplican técnicas estadísticas con las que pretenden analizar la información obtenida como resultado de un proceso de recolección de datos en cuya plantación no se hizo previsión del tipo de análisis que se podría necesitar para que los resultados fueran consecuentes con las hipótesis que desde un principio se ligan con todo proceso de indagación empírica, sistemática, controlada y reproducible -investigación- que busca resolver un problema especifico. Por ello, cuando se trata de interpretar los resultados de un estudio se pueden presentar errores respecto a la validez de los resultados obtenidos, especialmente cuando de manera empírica se quiere establecer el nivel de significación y, además, aclarar lo relacionado con el error que se produce cuando se acepta como válido un hallazgo que se origina por no haber formulado la hipótesis de trabajo (Error de tipo I).


Usually health professionals and people with little knowledge of statistics when involved with quantitative research they are faced to make statistical techniques to fulfill the data analysis resulting from a previous data collection. Generally they state hypothesis and later the information analysis can support the evidence in favor or against such hypothesis. In that point commonly they are faced to confusion when they try to interpret p value and type I error. The concept of p value and significance level will be approached in this paper and the difference among them will be cleared.
