Factores relacionados al interés e intención al uso de profilaxis preexposición al VIH en hombres gay y/o bisexuales, Colombia / Factors related to the interest and intention of using pre-exposure prophylaxis for HIV in gay and/or bisexual men, Colombia / Fatores relacionados ao interesse e intenção de usar profilaxia pré-exposição ao HIV em homens gays e/ou bissexuais, Colômbia

Resumen Introducción: la profilaxis preexposición al VIH (PrEP) ha demostrado disminuir la incidencia del VIH, pero su adopción en Colombia es aún incipiente. Para avanzar en la implementación de la PrEP como intervención de salud pública es necesario conocer el interés de las poblaciones en riesgo de VIH y los factores que facilitarían su uso. Objetivo: identificar los factores relacionados con el interés e intención de tomar PrEP en hombres gay/bisexuales. Metodología: estudio transversal analítico en una muestra no probabilística en ciudades principales de Colombia. Se exploraron las características sociodemográficas, conocimiento, motivaciones, habilidades conductuales y factores psicosociales, se utilizaron modelos logísticos para estimar la relación de estos factores con el interés y la intención de usar la PrEP. Resultados y conclusiones: participaron 552 hombres gay/bisexuales, 301 (54 %) reclutados en línea y 251 en persona. Solo el 40 % de la muestra sabía de la existencia de PrEP. 57.4 % (IC95%:54.9%-62.4%) reportaron interés e 52.9 % (IC95%: 48.5%-57.3%) intención de usar PrEP. El interés y la intención de usar la PrEP se relacionaron con actitudes y normas positivas hacia PrEP, así como con mayores habilidades relacionadas con servicios de PrEP. El estigma hacia la PrEP y los síntomas depresivos se relacionaron con menor interés e intención. Los resultados sugieren la necesidad de fomentar la información sobre PrEP, especialmente en poblaciones con más desventajas sociales y que experimentan más estigma, al igual que desarrollar intervenciones comunitarias que apoyen las motivaciones y las habilidades para usar la PrEP.

Abstract Introduction: HIV pre-exposure prophylaxis (PrEP) has been shown to reduce the incidence of HIV, but its adoption in Colombia is still beginning. To advance the implementation of PrEP as a public health intervention, it is necessary to know the interest of populations at risk of HIV and the factors that would facilitate its use. Objective: Identify factors related to interest and intention to take PrEP in gay/bisexual men. Methodology: Analytical cross-sectional study in a non-probabilistic sample in main cities of Colombia. Sociodemographic characteristics, knowledge, motivations, behavioral skills, and psychosocial factors were explored; logistic models were used to estimate the relationship of these factors with interest and intention to use PrEP. Results and conclusions: 552 gay/bisexual men participated, 301 (54%) recruited online and 251 in person. Only 40% of the sample knew of the existence of PrEP. 57.4% (95% CI: 54.9%-62.4%) reported interest and 52.9% (95% CI: 48.5%-57.3%) intention to use PrEP. Interest and intention to use PrEP were related to positive attitudes and norms toward PrEP, as well as greater skills related to PrEP services. Stigma toward PrEP and depressive symptoms were related to lower interest and intention. Our results suggest the need to promote information about PrEP, especially in populations with more social disadvantages and who experience more stigma, as well as to develop community interventions that support motivations and skills to use PrEP.

Resumo Introdução: Foi demonstrado que a profilaxia pré-exposição ao VIH (PrEP) reduz a incidência do VIH, mas a sua adopção na Colômbia está apenas a começar. Para avançar na implementação da PrEP como intervenção de saúde pública, é necessário conhecer o interesse das populações em risco de VIH e os fatores que facilitariam a sua utilização. Objetivo: Identificar fatores relacionados ao interesse e intenção de tomar PrEP em homens gays/bissexuais. Metodologia: Estudo analítico transversal em amostra não probabilística nas principais cidades da Colômbia. Foram exploradas características sociodemográficas, conhecimentos, motivações, habilidades comportamentais e fatores psicossociais; modelos logísticos foram utilizados para estimar a relação desses fatores com o interesse e intenção de uso da PrEP. Resultados e conclusões: Participaram 552 homens gays/bissexuais, 301 (54%) recrutados online e 251 pessoalmente. Apenas 40% da amostra sabia da existência da PrEP. 57,4% (IC 95%: 54,9%-62,4%) relataram interesse e 52,9% (IC 95%: 48,5%-57,3%) intenção de usar a PrEP. O interesse e a intenção de usar a PrEP estavam relacionados com atitudes e normas positivas em relação à PrEP, bem como com maiores competências relacionadas com os serviços de PrEP. O estigma em relação à PrEP e os sintomas depressivos foram relacionados com menor interesse e intenção. Os nossos resultados sugerem a necessidade de promover informação sobre a PrEP, especialmente em populações com mais desvantagens sociais e que sofrem mais estigma, bem como desenvolver intervenções comunitárias que apoiem motivações e competências para usar a PrEP.

Barriers and facilitators to HIV pre-exposure prophylaxis uptake among transgender women in Colombia: A qualitative analysis using the COM-B model.

Transgender women [TGW] in Colombia are disproportionately affected by HIV due to their low sociodemographic conditions, varied risk behaviours, difficulty accessing health services, and discrimination. Offering pre-exposure prophylaxis [PrEP] as part of a combination of prevention strategies is an appropriate option for this population to reduce their risk of HIV infection. However, little is known about how to implement a PrEP program for TGW in Colombia. Between June and October 2020, we conducted individual interviews with 16 TGW from four different cities in Colombia. The interviews assessed contextual influences, knowledge, skills, perceptions, and beliefs. We used qualitative thematic analysis to identify themes and the Capability, Opportunity, Motivation, and Behavior framework to further delineate barriers and possible interventions. After delineating the main themes across the three subdomains of the model, nine barriers were identified: one related to capability, knowledge, and perception of PrEP; six related to opportunity, which includes, family relations, sexual work environment, stable partner relations, interactions with healthcare workers, health service provision, and community interactions and opportunities; and two related to motivation, mental health, and concerns about medication side effects. Mapping barriers with interventions generated the following intervention functions: education, training, enablement, and environmental structure; and the following policy functions: communication/marketing, legislation, and changes in service provision. Examples of possible interventions are presented and discussed.

Applying implementation science frameworks to identify factors that influence the intention of healthcare providers to offer PrEP care and advocate for PrEP in HIV clinics in Colombia: a cross-sectional study.

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.

AC-2020-12-1420.R1 - HIV care providers' familiarity, concerns, and attitudes about HIV PrEP in Colombia: insights from the PrEP-Col-Study.

In 2019, Colombia approved the combination of tenofovir disoproxil fumarate/emtricitabine for HIV Pre-Exposure Prophylaxis (PrEP). Therefore, we conducted a situational analysis in HIV-care providers to identify barriers and facilitators for PrEP implementation. A survey was applied to a non-probabilistic sample of health care workers of HIV-specialized clinics. We examined PrEP awareness and familiarity, comfort with PrEP-related activities, perceived barriers for PrEP implementation, concerns, and attitudes. Poisson regressions assessed the relationship between these factors and the variable "having a plan to offer PrEP". The participation rate was 41% and included physicians (42.6%) and other health professionals (57.4%). Fifty-one percent of the participants reported more than five years of experience caring for people living with HIV. Forty-two percent of non-physician health care workers were nurses. Most reported high familiarity/comfort with PrEP-relevant activities. Concerns about PrEP were prevalent (> 50%) and included causing more harm than good, reducing condom use, medication non-adherence, drug resistance, and healthcare system barriers. Physicians had a plan to offer PrEP (72.2%) more often than other health professionals (52.6). Having a plan to offer PrEP was related to PrEP knowledge and comfort assessing sexual behavior and providing HIV counseling. Overall, about half of HIV-care providers seemed ready to offer PrEP and constitute an asset for PrEP implementation efforts in Colombia. PrEP awareness among non-physicians, PrEP concerns, and negative attitudes need to be addressed to enhance implementation.

Scales to Assess Knowledge, Motivation, and Self-Efficacy for HIV PrEP in Colombian MSM: PrEP-COL Study.

OBJECTIVE: We evaluated the construct validity Spanish version of knowledge, stigma, norms, and self-efficacy scales regarding PrEP in MSM. METHODS: Sample of 287 MSM. Exploratory confirmatory factor analysis and item response theory were used to validate the constructs. Correlations and confidence interval-based estimation of relevance analyses were conducted to correlate the scales with willingness and intention to use PrEP. RESULTS: Attitude, stigma, and descriptive and subjective norms scales showed good construct validity and were related to intention and willingness to use PrEP. However, the knowledge scale and self-efficacy scales require further refinement. CONCLUSIONS: The study provides useful information for assessing information, motivation, and self-efficacy related to PrEP use. Our results could be used to test the scales and the theoretical model in other contexts to confirm their usefulness.

Adaptation and Pilot Evaluation of an Intervention Addressing the Sexual Health Needs of Gay Men Living with HIV Infection in Colombia.

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.

Psychometric properties of a Spanish version of the 10-item Berger's stigma scale in Colombia: a validation study / Propiedades psicométricas de una versión en español de la escala de Berger de diez ítems en Colombia: un estudio de validación

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.

Application of the "syndemics" theory to explain unprotected sex and transactional sex: A crosssectional study in men who have sex with men (MSM), transgender women, and non-MSM in Colombia. / Aplicación de la teoría de la "sindemia" para entender el sexo sin protección y el sexo comercial: un estudio transversal en hombres que tienen sexo con hombres (HSH), mujeres transexuales y hombres que no tienen sexo con hombres en Colombia

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.

Examining a syndemic framework for HIV and Sexually Transmitted Infections Risk in Cali, Colombia / Examinando un marco sindémico para el VIH y el riesgo de infecciones de transmisión sexual en Cali, Colombia / Examinando um marco sindémico para o vih e o risco de infeções de transmissão sexual em Cali, Colômbia

Objective: We examined the role played by four psychosocial conditions: forced sex, early sexual initiation, and misuse of alcohol and illicit drugs on the risk of HIV and sexually transmitted infections in Cali-Colombia between 2013 and 2015. Methods: Using data from an HIV counseling and testing campaign in Cali, Colombia, we tested the effect of the accumulation and interactions of the four psychosocial conditions on both outcomes. Results: A total of 604 participants were representative subjects from key affected communities: men who have sex with men, transgender women and female sex workers. A total of 733 participants were heterosexual women and men. Only drug abuse was associated with HIV positivity (Prevalence ratio=2.3, CI 95%: 1.3­4.1), while all psychosocial conditions were associated with sexually transmitted infection history. The accumulation of the syndemic conditions was related to a higher likelihood of sexually transmitted infection history. None of the interactions tested was significant. Conclusions: Our findings highlight the importance of comprehensive mental health interventions in addressing HIV epidemics in Colombia.

Objetivo: Examinar el papel desempeñado por cuatro afecciones psicosociales: sexo forzado, iniciación sexual temprana, uso inadecuado de alcohol y drogas ilícitas en el riesgo de VIH e infecciones de transmisión sexual, en Cali-Colombia entre 2013-2015. Métodos: Utilizando datos de una campaña de consejería y pruebas de VIH en Cali, Colombia, probamos el efecto de la acumulación e interacciones de las cuatro condiciones psicosociales en la positividad al VIH y la positividad a otras enfermedades de transmisión sexual. Resultados: 604 participantes de las principales comunidades afectadas: hombres que tienen sexo con hombres, mujeres transgénero y trabajadoras sexuales. 733 participantes mujeres y hombres heterosexuales.

Só, abuso de drogas se associou com positividade VIH (Razão de prevalência = 2.3, IC 95%: 1.3­4.1), enquanto que, todas as condições psicossociais se associaram com história de infeções de transmissão sexual. Acumulação de condições sindémicas (palavra que reúne o social e o biológico) se relacionou com maior probabilidade de história de infeções de transmissão sexual. Nenhuma interação provada foi significativa. Conclusões: Nossos descobrimentos ressaltam a importância de intervenções integrais de saúde mental para abordar a epidemia de VIH na Colômbia.

Another piece of the Zika puzzle: assessing the associated factors to microcephaly in a systematic review and meta-analysis.

BACKGROUND: Although it is known that Zika virus (ZIKV) infection during pregnancy may lead to microcephaly in the fetus, the prognostic factors associated with this tragic disorder remain unclear. We conducted a systematic review and meta-analysis to assess the prognostic factors associated with the incidence of microcephaly in congenital ZIKV infection. METHODS: We conducted a comprehensive search in Ovid MEDLINE, Ovid MEDLINE (R) Epub ahead of print, Embase, Embase Classic, Web of Science, CINAHL, Cochrane CENTRAL, LILACS, and various thesis databases to identify human studies reporting microcephaly associated with congenital ZIKV infection. We requested primary data from the authors of the included studies to calculate summary estimates and conduct the meta-analysis of the most prevalent factors. RESULTS: We screened 4106 titles and abstracts, and identified 12 studies for inclusion in the systematic review. The assessment of ZIKV infection and the definition of microcephaly varied among studies. A total of 6154 newborns/fetuses were enrolled; of those, 1120 (18.20%) had a diagnostic of ZIKV infection, of which 509 (45.45%) were diagnosed with microcephaly. Nine studies addressed the link between congenital ZIKV infection and neurological findings in newborns/fetuses. Half of the studies provided primary data. Three out of 11 factors of interest seem to be prognostic factors of microcephaly: infant's sex - males compared to females: Relative Risk (RR) 1.30, 95% Confidence Interval (95% CI) 1.14 to 1.49; the stage of pregnancy when infection occurred - infection in the first trimester of pregnancy compared to infection at other stages of pregnancy: RR 1.41, 95% CI 1.09 to 1.82; and asymptomatic infection compared to symptomatic infection during pregnancy: RR 0.68; 95% CI 0.60 to 0.77. CONCLUSION: Our findings support the female-biased resistance hypothesis and reinforce the risk associated with the stage of pregnancy when ZIKV infection occurs. Continued surveillance of ZIKV infection during pregnancy is needed to identify additional factors that could contribute to developing microcephaly in affected fetuses. PROTOCOL REGISTRATION: This systematic review was registered with the International Prospective Register of Systematic Reviews (PROSPERO), registration no. CRD 42018088075.

Application of the "syndemics" theory to explain unprotected sex and transactional sex: A cross- sectional study in men who have sex with men (MSM), transgender women, and non-MSM in Colombia / Aplicación de la teoría de la "sindemia" para entender el sexo sin protección y el sexo comercial: un estudio transversal en hombres que tienen sexo con hombres (HSH), mujeres transexuales y hombres que no tienen sexo con hombres en Colombia

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.

Psychometric properties and validity of the Center for Epidemiological Studies Depression Scale (CES-D) in a population attending an HIV clinic in Cali, Colombia / Propiedades psicométricas y validez de la escala de depresión del Center for Epidemiological Studies (CES-D) en personas atendidas en una clínica de HIV en Cali, Colombia

INTRODUCTION: Depression in people living with HIV/AIDS is associated with poor health outcomes. Despite this, assessment of depressive symptoms is not a routine clinical practice in the care of people with HIV in Colombia. One reason could be the lack of validated depression screening scales for this population. OBJECTIVE: To test the reliability and construct validity of the 20- and 10-item-Center for Epidemiological Studies Depression Scale in patients attending an HIV clinic in Cali, Colombia. MATERIALS AND METHODS: A non-random sample of 105 adults was enrolled. The 20 item-CES-D (CES-D-20) scale was administered twice: At baseline and 2-4 weeks later. We calculated the Cronbach's alpha coefficient and the intraclass correlation coefficient. In addition, we used an exploratory and confirmatory factorial analysis, as well as the item response theory to assess the validity of the scale. RESULTS: Most participants were men (73%), with a mean age of 40 years, 53% of whom had not completed high school. Cronbach's coefficients were 0.92 and 0.94 at baseline and at the second interview, respectively. The intraclass correlation was 0.81 (95% CI: 0.72-0.88). Although all 20 items loaded distinctly in 4 factors, 5 items did not load as expected. The structure factor of the CES-D-20 was not confirmed, as 4 items had poor goodness of fit. The CES-D-10 appeared to perform better in this population. CONCLUSIONS: These results support the reliability and validity of the CES-D-10 instrument to screen for depressive symptoms in people living with HIV in Colombia.

Introducción. La depresión en personas con HIV/sida se asocia con resultados negativos para la salud. La evaluación de los síntomas depresivos no es una práctica clínica rutinaria en el cuidado de personas con HIV/sida en Colombia, lo cual puede deberse a la carencia de escalas validadas para la tamización de la depresión en esta población. Objetivo. Evaluar la reproducibilidad y validez de constructo de dos versiones de la escala de depresión del Center for Epidemiological Studies (CES-D), la de 20 ítems y la de 10 ítems, en personas con HIV/sida atendidas en una clínica de Cali, Colombia. Materiales y métodos. Se seleccionó una muestra no probabilística de 105 adultos con HIV/sida. La escala CES-D se utilizó dos veces (línea basal y 2 a 4 semanas después). La consistencia interna fue evaluada con el coeficiente alfa de Cronbach. La reproducibilidad se evaluó con el coeficiente de correlación intraclase. Para verificar la validez del constructo se utilizó un análisis factorial exploratorio y la teoría de respuesta al ítem. Resultados. El 73 % de la muestra correspondía a hombres, la edad promedio fue de 40 años y el 53 % tenía baja escolaridad. El coeficiente alfa de Cronbach fue de 0,92 (línea basal) y de 0,94 (segunda entrevista). El coeficiente de correlación intraclase fue de 0,81 (IC95% 0,72-0,88). Aunque en cuatro de los factores en la escala de 20 ítems claramente hubo carga factorial, cinco de los ítems no tuvieron un ajuste adecuado. La CES-D de 10 ítems parece funcionar mejor en esta población. Conclusiones. Los resultados respaldaron la reproducibilidad y la validez de la escala CES-D para la tamización de síntomas depresivos en personas con HIV/sida en Colombia.

HIV Testing and Counselling in Colombia: Local Experience on Two Different Recruitment Strategies to Better Reach Low Socioeconomic Status Communities.

HIV testing rates remain very low in Colombia, with only 20% of individuals at risk ever tested. In order to tackle this issue, the Corporacion de Lucha Contra el Sida (CLS) has implemented a multidisciplinary, provider-initiated, population-based HIV testing/counselling strategy named BAFI. In this report, we describe the experience of CLS at reaching populations from low socioeconomic backgrounds in 2008-2009. Two different approaches were used: one led by CLS and local health care providers (BAFI-1) and the other by CLS and community leaders (BAFI-2). Both approaches included the following: consented HIV screening test, a demographic questionnaire, self-reported HIV knowledge and behaviour questionnaires, pre- and posttest counselling, confirmatory HIV tests, clinical follow-up, access to comprehensive care and antiretroviral treatment. A total of 2085 individuals were enrolled in BAFI-1 and 363 in BAFI-2. The effectiveness indicators for BAFI-1 and BAFI-2, respectively, were HIV positive-confirmed prevalence = 0.29% and 3.86%, return rate for confirmatory results = 62.5% and 93.7%, return rate for comprehensive care = 83.3% and 92.8%, and ART initiation rate = 20% and 76.9%. Although more people were reached with BAFI-1, the community-led BAFI-2 was more effective at reaching individuals with a higher prevalence of behavioural risk factors for HIV infection.

Resistencia a fármacos en pacientes en tratamiento antirretroviral, Cali, Colombia, 2008-2010 / HIV drug resistance in ART-experienced patients in Cali, Colombia, 2008-2010

Introducción. En Colombia se ha publicado poco sobre farmacorresistencia del VIH en pacientes que reciben tratamiento antirretroviral. Las guías de VIH de Colombia de 2006, no recomiendan el uso de los estudios de genotipo de resistencia en pacientes nunca expuestos a medicamentos antirretrovirales ni después del primer fracaso terapéutico. Objetivo. Determinar la frecuencia de mutaciones de resistencia y el grado de sensibilidad/resistencia del VIH a los antirretrovirales en pacientes que han recibido tratamiento antirretroviral. Materiales y métodos. Se reclutó una muestra no probabilística de 170 pacientes con infección por VIH que recibían tratamiento antirretroviral, experimentaban fracaso virológico y que tenían estudios de genotipo de resistencia. Se estudió la farmacorresistencia del VIH en dos grupos: estudios de genotipo de resistencia tempranos Vs . tardíos. Resultados. El tipo de resistencia más frecuente en pacientes bajo tratamiento antirretroviral, afectó a los inhibidores no nucleosídicos (76 %). El grupo de estudio tardío tuvo mayor riesgo de resistencia a inhibidores nucleosídicos y a los inhibidores de proteasa, mayor número de mutaciones de resistencia y mayor complejidad de las resistencias, que el grupo de estudio temprano. También, se encontró un alto grado (30 %) de resistencia cruzada a los inhibidores nucleosídicos en el grupo de estudio tardío. Los medicamentos menos afectados fueron tenofovir y darunavir. Conclusiones. Los resultados de este estudio sugieren que practicar estudios de genotipo de resistencia tardíos se asocia con altos niveles de resistencia, lo cual puede restringir el uso de un gran número de antirretrovirales esenciales en esquemas subsiguientes. Es necesario revisar las actuales recomendaciones sobre el uso de dichos exámenes en las guías colombianas de manejo de VIH.

Introduction: Little has been published in Colombia on HIV drug resistance in patients taking antiretroviral treatment (ART). Currently, the Colombian guidelines do not recommend the use of genotypic antiretroviral resistance tests (GART) for treatment-naive patients or for those experiencing a first therapeutic failure. Objective: To determine the frequency of relevant resistance mutations and the degree of susceptibility/ resistance of HIV to antiretroviral drugs (ARVs) in ART-experienced patients. Materials and methods: A non-random sample of 170 ART-experienced HIV patients with virologic failure and who underwent GART was recruited. A study of HIV drug resistance was carried out in two groups of patients: one group that underwent early GART and the other group that received late GART testing. Results: The most frequent type of resistance affected the non-nucleoside class (76%). The late-GART group had higher risk of nucleoside analog and protease inhibitor drug resistance, a higher number of resistance mutations and more complex mutational profiles than the early-GART group. A high cross resistance level (30%) was found in the nucleoside analog class. The least affected medications were tenofovir and darunavir. Conclusions: Our results suggest that performing GART late is associated with levels of ARV resistance that could restrict the use of an important number of essential ARV in subsequent regimens. There is a need to revise the current recommendations to include GART prior to start of treatment and after the first virologic failure.

Resistencia transmitida del virus de la inmunodeficiencia humana en pacientes sin exposición previa a tratamiento antirretroviral, Cali, Colombia, 2010 / Transmitted HIV Resistance in ART-Naïve Patients in Cali, Colombia, 2010

Introducción: En Colombia, existe poca información publicada sobre farmacorresistencia transmitida en el virus de inmunodeficiencia humana (VIH), y actualmente, las pruebas genotípicas de resistencia no son recomendadas por las guías colombianas para pacientes nunca expuestos ( naïve ) a terapia antirretroviral (TAR). Se condujo un estudio para determinar la frecuencia de resistencias transmitidas en pacientes naïve a TAR, quienes fueron atendidos en una clínica especializada en VIH/síndrome de inmunodeficiencia adquirida en Cali, Colombia. Metodología: Se realizó un estudio transversal en 152 pacientes adultos elegibles, con infección confirmada por VIH, naïve a TAR, con pruebas genotípicas de resistencia disponibles, y que accedieron a participar. El período de reclutamiento fue de 2008 a 2010. Las mutaciones de resistencias incluidas en el análisis fueron las definidas por la Organización Mundial de la Salud 2009 e International AIDS Society-USA 2010. Adicionalmente, se recolectó información sociodemográfica y condiciones relacionadas con el VIH. Resultados: La edad promedio fue 32 ± 10,2 años, 76% fueron hombres. La frecuencia de resistencia primaria fue de 6,6% (según la lista de Bennett-Organización Mundial de la Salud 2009), pero se encontró algún nivel de resistencia hasta en un 11,8% de los casos (al considerar mutaciones de la lista International AIDS Society-USA 2010). Las mutaciones más comunes fueron K103N/S (2%), F77L (2%) y M46L (2%). Mutaciones a los inhibidores no nucleosídicos de transcriptasa reversa fueron encontradas en 5,3%, mutaciones a los inhibidores no nucleosídicos de transcriptasa reversa en 3,9% y mutaciones a inhibidor de proteasa en 2% de las secuencias. El único factor relacionado con la resistencia primaria fue la duración de la infección por VIH. Conclusiones: La frecuencia de resistencia transmitida es similar a la encontrada en estudios previos en Colombia y en otros países con amplio uso de antirretrovirales, y está por encima del umbral sobre el cual sería costo-efectivo incluir el estudio genotípico de resistencias como test de rutina antes de la iniciación de la TAR, especialmente en pacientes con infección por VIH de menos de un año de duración.

Introduction: In Colombia, little has been published on HIV-transmitted drug resistance, and genotype resistance testing (GART) is not recommended for antiretroviral therapy (ART)-Naïve patients, according to Colombian HIV guidelines. We conducted a study to determine the frequency of HIV-transmitted drug resistance from a sample of ART-Naïve patients attending an HIV clinic in Cali, Colombia. Methodology: A cross-sectional study was carried out on 152 eligible adult patients with confirmed HIV infection who were ART-Naïve, had HIV GART results, and who agreed to participate. The recruitment period was from 2008 to 2010. Resistance mutations included in the analysis are those defined by the WHO- 2009 and IAS-USA, 2010. Additional data was collected, including socio-demographic characteristics and HIV-related conditions. Results: The mean age was 32 ±10.2 years; 76% were men. Frequency of transmitted drug resistance was 6.6%, but some level of resistance was found in up to 11.8% of total cases (if IAS-USA 2010 mutations were also included). The most common mutations were K103N/S (2%), F77L (2%) and M46L (2%). NNRTI mutations were found in 5.3%, NRTI mutations in 3.9% and PI mutations in 2% of the sequences. The only factor associated with primary resistance was the duration of HIV infection.
