ABSTRACT

Resumen En 2019, México fue uno de los primeros países en Latinoamérica en comprometer recursos para eliminar la hepatitis C antes de 2030. Un año después de este compromiso, la pandemia mundial de COVID-19 desvió la atención hacia las necesidades inmediatas de salud para combatir la propagación de esta última. Como resultado, los esfuerzos para implementar programas de prevención y manejo de la hepatitis C se suspendieron indefinidamente. Asimismo, las poblaciones con alto riesgo de contraer el virus de la hepatitis C y que representan el mayor peso de la epidemia nacional, como las personas que se inyectan drogas y las personas que viven con infección por el virus de la inmunodeficia humana, permanecen expuestas a disparidades de salud extremas que potencialmente se han exacerbado durante la pandemia de COVID-19. En este artículo discutimos el impacto potencial que la pandemia de COVID-19 ha tenido sobre los esfuerzos de eliminación de la hepatitis C en México y la necesidad urgente de reanudarlos, ya que sin ellos los objetivos de eliminación no se alcanzarán en el país en 2030.


Abstract In 2019, Mexico was one of the first countries in Latin America to commit resources to achieve hepatitis C elimination by 2030. One year after this commitment, the global COVID-19 pandemic diverted attention to address immediate health needs to combat the spread of the disease. As a result, efforts to implement hepatitis C prevention and management programs were indefinitely postponed. Furthermore, populations at high risk of contracting the hepatitis C virus (HCV) and who bear the greatest burden of HCV national epidemic, including people who inject drugs and people who live with human immunodeficiency virus infection, remain exposed to extreme health disparities, which have potentially been exacerbated during the COVID-19 pandemic. In this article, we discuss the potential impact the COVID-19 pandemic has had on HCV elimination efforts in Mexico and the urgent need to resume them, since without these efforts, HCV elimination goals are likely not be achieved in the country by 2030.

ABSTRACT

ABSTRACT OBJECTIVE To characterize recent HIV infections among newly diagnosed men who have sex with men and transgender women in Tijuana. METHODS Limiting Antigen (LAg)-Avidity testing was performed to detect recent HIV infection within a cohort of newly-diagnosed men who have sex with men and transgender women in Tijuana. Logistic regression was used to determine characteristics associated with recent infection. A partial transmission network was inferred using HIV-1 pol sequences. Tamura-Nei 93 genetic distances were measured between all pairs of sequences, and the network was constructed by inferring putative transmission links (genetic distances ≤ 1.5%). We assessed whether recent infection was associated with clustering within the inferred network. RESULTS Recent infection was detected in 11% (22/194) of newly-diagnosed participants. Out of the participants with sequence data, 60% (9/15) with recent infection clustered compared with 31% (43/139) with chronic infection. Two recent infections belonged to the same cluster. In adjusted analyses, recent infection was associated with years of residence in Tijuana (OR = 1.5; 95%CI 1.01-1.09), cocaine use (past month) (OR = 8.50; 95%CI 1.99-28.17), and ever experiencing sexual abuse (OR = 2.85; 95%CI 1.03-7.85). DISCUSSION A total of 11% of men newly diagnosed with HIV who have sex with men and transgender women in Tijuana were recently infected. The general lack of clustering between participants with recent infection suggests continued onward HIV transmission rather than an outbreak within a particular cluster.

ABSTRACT

Abstract Introduction Needle and syringe programs (NSP) reduce syringe sharing and HIV transmission among people who inject drugs (PWID). However, their effectiveness relies on sufficient individual and population level coverage. In Tijuana, Mexico, the Global Fund (GF) supported NSP during 10/2011-12/2013, but withdrew funds at the end of 2013 following Mexico's re-classification as an upper-middle income country. Objective We tested the hypothesis of higher NSP access and lower receptive syringe sharing among PWID in Tijuana during the GF support period compared to pre-GF initiation and post-GF withdrawal. Method We used data from an ongoing cohort study of PWID in Tijuana (03/2011-10/2015) to implement a segmented regression analysis investigating changes in the self-reported probability of NSP access, reported difficulty in finding sterile syringes and receptive syringe sharing before GF initiation and after GF discontinuation. Results We found a large significant increase in the probability of NSP access (+.07) and decrease in receptive syringe sharing (-.23) right after GF initiation, which continued over the GF period. Subsequently, we found a significant decline in NSP access (-.05) and an increase in receptive syringe sharing (+.02) right after post-GF withdrawal, which continued thereafter. Discussion and conclusion We demonstrated significant temporal changes in NSP access and receptive syringe sharing among PWID in Tijuana after GF initiation and withdrawal consistent with our hypothesis. Coordinated efforts with local authorities are needed to sustain major coverage NSP in settings receiving GF or external aid to guarantee continuity of harm reduction services and prevent reinside in risk behaviors associated with HIV transmission.


Resumen Antecedentes Los programas de intercambio de jeringas (PIJ) reducen la transmisión del VIH entre las personas que se inyectan drogas (PID). Sin embargo, su efectividad depende de una cobertura suficiente a nivel individual y poblacional. En Tijuana, México, el Fondo Mundial (FM) apoyó los PIJ durante 10/2011-12/2013, pero retiró los fondos a fines de 2013. Objetivo Probamos la hipótesis de un mayor acceso a los PIJ y un menor uso receptivo de jeringas compartidas entre las PID en Tijuana durante el período de financiamiento del FM en comparación con el periodo anterior y posterior al FM. Método Usando datos de un estudio de cohorte de PID en Tijuana (03/2011-10/2015), implementamos un análisis de regresión segmentado para investigar cambios en la probabilidad de acceso a las PIJ, la dificultad para encontrar jeringas estériles y el uso receptivo de jeringas compartidas sobre los periodos pre-, durante y post-FM. Resultados Identificamos un aumento en la probabilidad de acceso a PIJ (+.07) y una disminución en el uso de jeringas compartidas (-.23) justo después del inicio del FM, ambos significativos, que se sostuvieron durante el período del FM. Después del retiro del FM, identificamos una disminución en el acceso a PIJ (-.05) y un aumento en el uso de jeringas compartidas (+.02), ambos también significativos. Discusión y conclusión Esfuerzos coordinados con las autoridades locales son necesarios para garantizar una mayor cobertura de los programas de reducción del daño, independientemente de financiamientos externos, para prevenir reincidir en las conductas de riesgo para el VIH en PID.

ABSTRACT

Objective. To compare distributions of human rights violations and disease risk; to juxtaposethese patterns against demographic and structural environmental variables, and to formulateimplications for structural interventions.Methods. Female sex workers who inject drugs were surveyed in Tijuana and CiudadJuarez, Mexico. Structured interviews and testing for sexually transmitted infections (STIs)were conducted (October 2008 to October 2009). Frequencies of individual and environmentalfactors, including police abuse, risk of HIV infection, and protective behaviors, were comparedbetween sites using univariate logistic regression.Results. Of 624 women, almost half reported police syringe confiscation despite syringesbeing legal; 55.6% reported extortion (past 6 months), with significantly higher proportions inCiudad Juarez (P < 0.001). Reports of recent solicitation of sexual favors (28.5% in Tijuana,36.5% in Ciudad Juarez, P = 0.04) and sexual abuse (15.7% in Tijuana, 18.3% in CiudadJuarez) by police were commonplace. Prevalence of STIs was significantly lower in Tijuanathan in Ciudad Juarez (64.2% and 83.4%, P < 0.001), paralleling the lower prevalence ofsexual risk behaviors there. Ciudad Juarez respondents reported significantly higher mediannumber of monthly clients (6.8 versus 1.5, P < 0.001) and lower median pay per sex act(US$ 10 versus US$ 20, P < 0.001) (in the past month). Relative to Tijuana, security deployment,especially the army’s presence, was perceived to have increased more in Ciudad Juarezin the past year (72.1% versus 59.2%, P = 0.001).Conclusions. Collateral damage from police practices in the context of Mexico’s drug conflictmay affect public health in the Northern Border Region. Itinerant officers may facilitate diseasespread beyond the region. The urgency for mounting structural interventions is discussed.


Objetivo. Comparar las distribuciones de las violaciones a los derechos humanos yel riesgo de enfermedades; yuxtaponer los patrones obtenidos con las variables demográficasy estructurales del entorno, y formular las implicaciones de llevar a cabointervenciones estructurales.Métodos. Se entrevistaron trabajadoras del sexo que consumían drogas inyectablesen Tijuana y Ciudad Juárez, México. Entre octubre del 2008 y octubre del 2009 sellevaron a cabo entrevistas estructuradas y pruebas para detectar infecciones de transmisiónsexual (ITS). Se compararon entre las dos ciudades las frecuencias de factoresindividuales y ambientales, como el abuso policial, el riesgo de infección por el VIH ylas conductas protectoras, usando regresión logística de una sola variable.Resultados. De 624 mujeres, casi la mitad comunicaron la confiscación de jeringaspor la policía a pesar de que es legal poseerlas; 55,6% informaron extorsión (en losúltimos 6 meses), con proporciones significativamente mayores en Ciudad Juárez(P < 0,001). Los informes de solicitación reciente de favores sexuales (28,5% en Tijuana,36,5% en Ciudad Juárez, P = 0,04) y de abuso sexual (15,7% en Tijuana, 18,3%en Ciudad Juárez) por la policía fueron comunes. La prevalencia de ITS fue significativamentemenor en Tijuana que en Ciudad Juárez (64,2% y 83,4%, P < 0,001), en formaanáloga a la menor prevalencia de conductas sexuales de riesgo en la primera ciudad.Las mujeres entrevistadas en Ciudad Juárez informaron una mediana del número declientes mensual significativamente mayor (6,8 frente a 1,5, P < 0,001) y una medianadel pago por acto sexual menor (US$ 10 frente a US$ 20, P < 0,001) en el último mes.En el último año, las mujeres entrevistadas percibieron un mayor aumento del desplieguede seguridad, especialmente la presencia del ejército, en Ciudad Juárez queen Tijuana (72,1% frente a 59,2%, P = 0,001).Conclusiones. Los daños colaterales derivados de las prácticas policiales en el contextodel conflicto de narcotráfico de México pueden afectar a la salud pública enla región de la frontera norte de México. Los oficiales itinerantes pueden facilitar lapropagación de enfermedades más allá de la región. Se analiza la urgencia para establecerintervenciones estructurales.
