Both hepatitis B virus (HBV) and hepatitis C virus (HCV) are major sources of morbidity and mortality worldwide; however, their prevalence in key groups in Colombia is not yet known. We aimed to analyse the prevalence of HBV and HCV and its associated factors in key groups who were treated at an institution providing health services in Colombia during 2019. This was a multiple-group ecological study that included 2,624 subjects from the general population, 1,100 men who have had sex with men (MSM), 1,061 homeless individuals, 380 sex workers, 260 vulnerable young people, 202 drug users, 41 inmates and 103 people from the lesbian, gay, bisexual and transgender community. Prevalence of infection with a 95% confidence interval and its associated factors was calculated for each group. Confounding variables were assessed using logistical regression and SPSS 25.0 software. Prevalence of HBV and HCV in the general population was 0.15% and 0.27%, respectively; 0.27% and 2.09% in MSM; 0.37% and 2.17% amongst homeless individuals; 0.26% and 0.0% amongst sex workers; 0.39% and 0.0% amongst vulnerable youth; and 5.94% and 45.54 amongst injecting drug users. In the multivariate HBV model, the explanatory variables included the study group, city of origin and the type of health affiliation; for HCV they were group, origin, sex, age group, health affiliation, use of drugs and hallucinogen use during sexual intercourse. A high prevalence of HBV and HCV were evidenced for both viral infections, which was, consequently, much higher within the key groups. The main associated factors that were identified related to origin and type of health affiliation and demonstrated a double vulnerability, that is, belonging to groups that are discriminated and excluded from many health policies and living under unfavourable socioeconomic conditions that prevent proper affiliation and health care.
Background: Research conducted on the prevalence of HIV/AIDS and its associated factors among key groups in Colombia is scarce. The few available studies show heterogeneity in their results and increasing trends of infection. This study analyses the prevalence of HIV and associated factors in key groups served at a health care institution in Colombia in 2019. Methods: We performed a cross-sectional study with the sample comprised of 5771 subjects from the general population, the LGBTI community, sex workers, people who inject drugs and prisoners. The diagnosis was based on a fourth-generation ELISA. Variables related to sociodemographics, healthcare, sexual risk factors and biological measures of infected subjects were analysed. Prevalence and odds ratios were calculated with 95% confidence intervals, and logistic regression models were performed to identify confounding variables and interactions between independent variables using SPSS 25.0. Results: The prevalence of HIV was 0.27% among the general population, 0.53% among sex workers, 0.66% among the homeless, 2.44% among transgender persons, 2.44% among prisoners, 5.36% among men who have sex with men and 7.92% among injection drug users. The explanatory model showed higher prevalence among men, those with higher education levels, those with no health coverage, those who have sex with people from key groups and those with sexually transmitted infections, with some interactions between the latter variables. Conclusion: A high prevalence of infection was found in the key groups, while the main explanatory factors for high infection rates were identified. The data show that national and global goals related to controlling HIV have not been achieved mainly in groups that are at a higher risk of obtaining and transmitting it and, paradoxically, also that are excluded from the national health coverage.
La resistencia bacteriana es un problema serio, de magnitud creciente y presentación universal, que reviste gran importancia, especialmente en los ambientes hospitalarios; los microorganismos más frecuentemente aislados de pacientes con infecciones intrahospitalarias son Staphylococcus aureus y Escherichia coli. En Medellín, sin embargo, Klebsiella pneumoniae ha cobrado gran importancia en años recientes debido a su gran incremento como agente causal de ese tipo de infecciones, lo que motiva esta revisión. Se incluyen los siguientes aspectos: microbiología, epidemiología, diseminación, resistencia a los beta-lactámicos y sus mecanismos, impacto clínico e importancia del problema en la ciudad.
La pandemia del VIH/SIDA sigue aumentando en el mundo y el problema no es menor en Colombia; por lo tanto, es urgente que el médico general y los profesionales de todas las disciplinas cuyos esfuerzos terapéuticos se enfocan sobre esta población reciban una adecuada formación para diagnosticar y tratar esta fatal enfermedad antes de que el paciente alcance sus estadios más avanzados en los que ya es irreversible. A lo largo de la historia ha ido cambiando el rol del maestro, pasando del que era autoritario hasta llegar al que es más cercano a sus alumnos, con el cual ellos se identifican y del cual adquieren un conocimiento técnico, pero sobre todo de quien adquieren pasión y deseo por el saber mediante una serie de competencias sociales, éticas, políticas y culturales, que lo capacitan integralmente. Si bien la enseñanza en grupos pequeños y el aprendizaje basado en problemas son herramientas muy útiles en diferentes escenarios pedagógicos, no existen antecedentes que orienten sobre cómo implementarlos en los diferentes aspectos relacionados con el VIH/SIDA. Por tal motivo, en el ámbito clínico hemos adoptado en la Facultad de Medicina de la Universidad de Antioquia el “aprendizaje basado en la ronda clínica”, metodología que motiva al alumno a pensar con una posición reflexiva, formándolo para un medio laboral donde debe primar el trabajo en equipo, pero siempre acompañado por su maestro quien mantiene una posición definitiva en las decisiones que se toman, logrando posteriormente que el alumno adopte una independencia tal que le permita tomar decisiones dirigidas hacia la búsqueda del conocimiento y del bienestar de sus pacientes.
