Challenges and opportunities for cancer stem cell-targeted immunotherapies include immune checkpoint inhibitor, cancer stem cell-dendritic cell vaccine, chimeric antigen receptor immune cells, and modified exosomes.

Cancer stem cells (CSCs) are associated with the tumor microenvironment (TME). CSCs induce tumorigenesis, tumor recurrence and progression, and resistance to standard therapies. Indeed, CSCs pose an increasing challenge to current cancer therapy due to their stemness or self-renewal properties. The molecular and cellular interactions between heterogeneous CSCs and surrounding TME components and tumor-supporting immune cells show synergistic effects toward treatment failure. In the immunosuppressive TME, CSCs express various immunoregulatory proteins, growth factors, metabolites and cytokines, and also produce exosomes, a type of extracellular vesicles, to protect themselves from host immune surveillance. Among these, the identification and application of CSC-derived exosomes could be considered for the development of therapeutic approaches to eliminate CSCs or cancer, in addition to targeting the modulators that remodel the composition of the TME, as reviewed in this study. Here, we introduce the role of CSCs and how their interaction with TME complicates immunotherapies, and then present the CSC-based immunotherapy and the limitation of these therapies. We describe the biology and role of tumor/CSC-derived exosomes that induce immune suppression in the TME, and finally, introduce their potentials for the development of CSC-based targeted immunotherapy in the future.

Retention and Viral Suppression Among Adolescents Newly Initiating Antiretroviral Therapy in Adult HIV Care in Lima, Peru: A Retrospective Cohort Study.

PURPOSE: Published data on outcomes among adolescents newly initiating antiretroviral treatment in the Latin American context are sparse. We estimated the frequency of sustained retention with viral load suppression (i.e., successful transition) and identified predictors of successful transition into adult care among youth (aged 14-21 years) with recently acquired HIV in Lima, Peru. METHODS: A retrospective cohort study was conducted among 184 adolescents and young adults who initiated antiretroviral therapy in an adult public sector HIV clinic between June 2014 and June 2019. Sustained retention (no loss-to-follow-up or death) with viral suppression was calculated for the first 12 and 24 months following treatment initiation. We conducted regression analyses to assess factors associated with successful transition to adult HIV care, including gender, age, occupation, nationality, pregnancy, same-sex sexual behavior, presence of treatment supporter, number of living parents, and social risk factors that may adversely influence health (e.g., lack of social support, economic deprivation). RESULTS: Patients were predominantly male (n = 167, 90.8%). Median age was 19 years (interquartile range: 18-21). Frequency of sustained retention with viral load suppression was 42.4% (78/184) and 35.3% (30/85) at 12 and 24 months following treatment initiation. In multivariable analyses, working and/or studying was inversely associated with successful transition into adult care at 12 months; number of known living parents (relative risk: 2.20; 95% confidence interval: 1.12, 4.34) and absence of social risk factors (relative risk: 1.68; 95% confidence interval: 0.91, 3.11) were positively associated with successful transition at 24 months. DISCUSSION: Sustained retention in HIV care was uncommon. Parental support and interventions targeting social risk factors may contribute to successful transition into adult HIV care in this group.

Recent HIV infection and annualized HIV incidence rates among sexual and gender minorities in Brazil and Peru (ImPrEP seroincidence study): a cross-sectional, multicenter study.

Background: HIV incidence estimation is critical for monitoring the HIV epidemic dynamics and the effectiveness of public health prevention interventions. We aimed to identify sexual and gender minorities (SGM) with recent HIV infections, factors associated with recent HIV infection, and to estimate annualised HIV incidence rates. Methods: Cross-sectional multicentre study in HIV testing services in Brazil and Peru (15 cities). Inclusion criteria: 18+ years, SGM assigned male at birth, not using pre-/post-exposure prophylaxis. We identified recent HIV infection using the Maxim HIV-1 LAg-Avidity EIA assay as part of a recent infection testing algorithm (RITA). Annualized HIV incidence was calculated using the UNAIDS/WHO incidence estimator tool. Multivariable logistic regression models were used to estimate factors associated with recent HIV infection. Trial registration: NCT05674682. Findings: From 31-Jan-2021 to 29-May-2022, 6899 individuals participated [Brazil: 4586 (66.5%); Peru: 2313 (33.5%)]; 5946 (86.2%) cisgender men, 751 (10.9%) transgender women and 202 (2.9%) non-binary/gender diverse. Median age was 27 (IQR: 23-34) years. HIV prevalence was 11.4% (N = 784/6899); 137 (2.0%) SGM were identified with recent HIV infection. The overall annualized HIV incidence rate was 3.88% (95% CI: 2.86-4.87); Brazil: 2.62% (95% CI: 1.78-3.43); Peru: 6.69% (95% CI: 4.62-8.69). Participants aged 18-24 years had higher odds of recent HIV infection compared to those aged 30+ years in both countries. Interpretation: Our results highlight the significant burden of HIV epidemic among SGM in large urban centres of Brazil and Peru. Public health policies and interventions to increase access to effective HIV prevention methods such as PrEP are urgently needed in Latin America.

HIV treatment cascade in regions of Peru with the highest HIV prevalence.

OBJECTIVES: To describe the HIV treatment cascade and care continuum in regions of highest HIV prevalence in Peru. METHODS: An observational longitudinal study was carried out in 14 tertiary hospitals in Peru. These are the main hospitals that administer antiretroviral treatment (ART) in the regions that represent approximately 95% of reports of HIV/AIDS cases in Peru in 2013. We included individuals older than 18 years newly diagnosed with HIV from 1 January 2011 to 31 December 2012. Medical records were reviewed until 2015. RESULTS: A total of 2119 people living with HIV (PLHIV) were identified in the selected health facilities (mean age = 35.26 years, 78% male). 97.25% [1845/1897; 95% confidence interval (CI): 96.4-97.9%] of the patients attended the consultation at least once during the follow-up, but only 64.84% (885/1365; 95% CI: 62.2-67.4%) attended within a month after the diagnosis. After starting ART, 74.63% (95% CI: 71.9-77.2%) of PLHIV remained in healthcare. Regardless of the time after diagnosis, 88.40% (1837/2078; 95% CI: 86.9-89.7%) of PLHIV started ART during the observation time. However, 78.68% (95% CI: 76.8-80.4%) did so during the first post-treatment year and only 28.88% (95% CI: 27.9-31.9%) after 1 month. After starting treatment, it was observed that 51.60% (95% CI: 49.2-54%) of PLHIV reached viral suppression during the follow-up period. CONCLUSIONS: Further analysis and improvements in the definition of indicators are required to achieve conclusive results; however, these data will give us a general understanding of the progress of Peruvian health policies in achieving the goal established by the WHO.

Patient and provider perceptions of a community-based accompaniment intervention for adolescents transitioning to adult HIV care in urban Peru: a qualitative analysis.

INTRODUCTION: Adolescents living with HIV (ALWH) experience higher mortality rates compared to other age groups, exacerbated by the suboptimal transition from paediatric to adult HIV care, during which decreased adherence to antiretroviral therapy (ART) and unsuppressed viremia are frequent. Care transition-a process lasting months or years-ideally prepares ALWH for adult care and can be improved by interventions that are youth-friendly and address psychosocial issues affecting ART adherence; however, such interventions are infrequently operationalized. Community-based accompaniment (CBA), in which laypeople provide individualized support and health system navigation, can improve health outcomes among adults with HIV. Here, we describe patient and provider perceptions of a novel HIV CBA intervention called "PASEO" for ALWH in Lima, Peru. METHODS: PASEO consisted of six core elements designed to support ALWH during and after the transition to adult HIV care. During 2019-2021, community-based health workers provided tailored accompaniment for ALWH aged 15-21 years over 9 months, after which adolescent participants were invited to provide feedback in a focus group or in-depth interview. HIV care personnel were also interviewed to understand their perspectives on PASEO. A semi-structured interview guide probing known acceptability constructs was used. Qualitative data were analysed using a framework analysis approach and emergent themes were summarized with illustrative quotes. RESULTS: We conducted five focus groups and 11 in-depth interviews among N = 26 ALWH and nine key-informant interviews with HIV care personnel. ALWH participants included males, females and one transgender female, and those with both early childhood and recent HIV infection. ALWH praised PASEO, attributing increased ART adherence to the project. Improved mental health, independence, self-acceptance and knowledge on how to manage their HIV were frequently cited. HIV professionals similarly voiced strong support for PASEO. Both ALWH and HIV professionals expressed hope that PASEO would be scaled. HIV professionals voiced concerns regarding financing PASEO in the future. CONCLUSIONS: A multicomponent CBA intervention to increase ART adherence among ALWH in Peru was highly acceptable by ALWH and HIV programme personnel. Future research should determine the efficacy and economic impact of the intervention.

Community-based accompaniment for adolescents transitioning to adult HIV care in urban Peru: a pilot study.

We piloted a community-based intervention to improve outcomes among adolescents living with HIV who were transitioning to adult-oriented care in Lima, Peru. We assessed feasibility and potential effectiveness, including within-person changes in self-reported adherence, psychosocial metrics (NIH Toolbox), and transition readiness ("Am I on TRAC" questionnaire, "Got Transition" checklist). From October 2019 to January 2020, we enrolled 30 adolescents (15-21 years). The nine-month intervention consisted of logistical, adherence and social support delivered by entry-level health workers and group sessions to improve health-related knowledge and skills and social support. In transition readiness, we observed within-person improvements relative to baseline. We also observed strong evidence of improvements in adherence, social support, self-efficacy, and stress, which were generally sustained three months post-intervention. All participants remained in treatment after 12 months. The intervention was feasible and potentially effective for bridging the transition to adult HIV care. A large-scale evaluation, including biological endpoints, is warranted.

RESUMEN: Piloteamos una intervención comunitaria para mejorar los resultados de adolescentes viviendo con el VIH que se encontraban en transición a la atención de VIH orientada a adultos en Lima, Perú. Evaluamos la viabilidad y la eficacia potencial, incluidos los cambios personales en la adherencia auto-reportada, criterios psicosociales (NIH Toolbox), y preparación para la transición (cuestionario "Estoy en el TRAC", lista de verificación "Got Transition"). Desde octubre de 2019 hasta enero de 2020, enrolamos a 30 adolescentes (15 a 21 años). La intervención de nueve meses consistió en apoyo logístico, de adherencia y social brindado por técnicos de enfermería y sesiones grupales para mejorar tanto el conocimiento y las habilidades relacionados con la salud, como el apoyo social. En cuanto a la preparación para la transición, observamos mejoras comparada con el basal. También observamos una fuerte evidencia de mejoras en la adherencia, apoyo social, autoeficacia y estrés, que se mantuvieron, generalmente, tres meses después del fin de la intervención. Todos los participantes seguían en tratamiento después de 12 meses. La intervención fue factible y potencialmente efectiva para tender un puente en la transición a la atención del VIH para adultos. Esto amerita una evaluación a mayor escala y que incluya criterios clínicos.

Antimicrobial Susceptibility of Neisseria gonorrhoeae Isolates From Peru, 2018 and 2019.

BACKGROUND: Currently, in Latin America, including Peru, the treatment of gonorrhea is still empiric and information regarding antimicrobial resistance is scarce in some countries because of the limited resources, which can contribute to the rising rates of reported multidrug-resistant gonococcal strains. In that context, it is mandatory to continuously monitor and report antimicrobial resistance in N. gonorrhoeae to update treatment recommendations. METHODS: This descriptive study analyzed genital and anal samples from symptomatic patients who attended 15 sexually transmitted infections health facilities from 8 different regions in Peru during the years 2018 to 2019 within the framework of Sentinel Surveillance. After establishing the presumptive diagnosis, the isolates were sent to the Laboratory of Sexually Transmitted Bacteria of the National Institute of Health of Peru in Lima where the species were confirmed (N = 165) and susceptibility profiles were determined. RESULTS: Among the 165 isolates, 95.2% corresponded to male patients, between 18 and 22 years of age (40.6%), half reported having a sexual partner and being heterosexual. Clinically, 89.7% manifested the presence of urethral exudate. Microbiology showed 95.2% of the isolates resistant to ciprofloxacin and 9.1% non-susceptible to azithromycin. Reduced susceptibility to ceftriaxone and cefixime was observed in 1.2% and 3.6% of the isolates respectively. All strains tested were susceptible to spectinomycin. CONCLUSIONS: This study demonstrated that in Peru, fluoroquinolones should not be recommended or used in N. gonorrhoeae infections due to the high percentage of resistant strains. In addition, nationwide access to gonococcal resistance testing, molecular diagnostics and antimicrobial stewardship should be implemented to control the spread of gonococcal antimicrobial resistance.

[Impact of SARS-CoV-2 pandemic on adolescents living with HIV in Lima, Peru]. / Impacto de la pandemia por SARS-CoV-2 en adolescentes que viven con el VIH en Lima, Perú.

Adolescents living with HIV (ALWH) have lower rates of virologic suppression and higher rates of immunologic decline compared to their older counterparts, potentially placing them at high-risk for developing severe SARS-CoV-2 disease. ALWH who are transitioning to adult care face additional challenges to remaining in care and adhering to treatment. In this special section we report the experiences of ALWH in the process of transitioning to adult HIV services during the COVID-19 pandemic. In first place, the government-mandated stay-at-home order has substantially limited access to full HIV care by restricting public transportation, HIV medication stock-outs, and the suspension of routine medical and laboratory appointments. In addition, financial hardship, uncertainty about their future plans, emotional stressors, lifestyle disruptions, and concerns of involuntary disclosure have further challenged continuity in care for this adolescent population.

Los adolescentes que viven con el VIH (AVVIH) tienen tasas más bajas de supresión virológica y tasas más altas de deterioro inmunológico en comparación con sus contrapartes mayores, colocándolos potencialmente en alto riesgo de enfermedad severa por SARS-CoV-2. Los AVVIH que están transicionando hacia el cuidado de adultos enfrentan dificultades adicionales para permanecer en el cuidado y adherirse al tratamiento antirretroviral. En esta sección especial reportamos el impacto observado en AVVIH transicionando al servicio de VIH para adultos durante la pandemia por SARS-CoV-2. En primer lugar, el acceso a la atención del VIH se ha visto perjudicado por la restricción del transporte público, la falta de antirretrovirales, y la suspensión de citas médicas y laboratoriales. Adicionalmente, dificultades financieras, incertidumbre sobre el futuro, estresores emocionales, alteración del estilo de vida y el temor de divulgar el diagnóstico involuntariamente han desafiado aún más la continuidad en la atención de esta población adolescente.

[Continuum of care of people living with HIV and gaps in achieving the 90-90-90 goals in Peru]. / Continuo de la atención de personas que viven con VIH y brechas para el logro de las metas 90-90-90 en Perú.

In 2013, the Joint United Nations Programme on HIV/AIDS (UNAIDS) proposed, in terms of public health, to end the HIV epidemic by 2030 by achieving the so-called 90-90-90 targets by 2020. This goal will only be possible if coverage in the HIV care continuum indicators is increased. With the methodology proposed by PAHO/WHO, this paper estimates the indicators of the continuum of care in Peru for 2014, consisting of diagnostic coverage, antiretroviral treatment (ART), and viral suppression in people living with HIV (PLHIV). Of the 72,000 PLHIV estimated in Peru for 2014, 64% were diagnosed, 56% and 55% were linked and retained in the system, respectively; 46% were receiving ART, and 36% had viral suppression. The main gaps identified were: 19,917 PLHIV did not know their diagnosis, 25,078 had no access to treatment, and 25,633 did not achieve viral suppression at study closing. This is the first estimation exercise of the continuum of care indicators in Peru. These indicators will serve as a baseline for the monitoring progress toward the 90- 90-90 Targets. It is also the starting point for analysis and research on the determinants of each gap and new proposals by authorities and actors involved in the fight against HIV in Peru.

En 2013, el Programa Conjunto de las Naciones Unidas sobre el VIH/Sida (ONUSIDA) propone, en términos de salud pública, poner fin a la epidemia de VIH hacia el 2030, mediante el logro de las denominadas Metas 90-90-90 hacia el 2020. Esta meta será posible solamente si se elevan las coberturas en los indicadores del continuo de la atención del VIH. En el presente artículo, utilizando la metodología propuesta por OPS/OMS, se estimaron los indicadores del continuo de la atención en el Perú para el 2014, consistentes en coberturas de diagnóstico, tratamiento antirretroviral (TARV) y supresión viral en las personas viviendo con VIH (PVV). De las 72 000 PVV estimadas en el Perú para el 2014, el 64% fueron diagnosticadas, el 56% y 55% vinculadas y retenidas en el sistema respectivamente, 46% recibían TARV y el 36% tuvieron supresión viral. Las principales brechas identificadas fueron: 19 917 PVV no conocían su diagnóstico, 25 078 no accedían al tratamiento y 25 633 no consiguieron supresión viral al cierre del estudio. Este es el primer ejercicio de estimación de los indicadores del continuo de la atención en el Perú. Estos indicadores servirán como línea de base para el monitoreo del avance hacia las Metas 90-90-90. Asimismo, constituye el punto de partida para el análisis e investigaciones en los determinantes de cada brecha y nuevas propuestas por parte de las autoridades y los actores involucrados en la lucha contra el VIH en el Perú.

This is the first estimation exercise of the continuum of care indicators in Peru. These indicators will serve as a baseline for the monitoring progress toward the 90-90-90 Targets. It is also the starting point for analysis and research on the determinants of each gap and new proposals by authorities and actors involved in the fight against HIV in Peru.

Prevención de la transmisión materno-infantil del VIH en gestantes y madres awajún y wampis de la región amazonas en Perú / Prevention of Maternal-Child Transmission of HIV in Pregnant Women and Mothers of the Awajun and Wampis Communities in the Amazon Region of Peru

RESUMEN Objetivos Identificar las barreras que limitan el cumplimiento de las medidas de prevención de la transmisión materno-infantil (TMI) del VIH, en comunidades indígenas de la región Amazonas en Perú. Materiales y métodos Investigación cualitativa con enfoque fenomenológico. Se realizaron entrevistas semiestructuradas a gestantes y madres de niños menores de un año de las comunidades indígenas awajún y wampis diagnosticadas con VIH durante el 2014-2015. Resultados Participaron 15 de 29 mujeres, siendo el 87% de la etnia awajún. Se identificaron limitaciones y posibles efectos cuando se impone medidas sanitarias para la prevención de la TMI. Dada la concepción que tienen de las enfermedades, que implica la presencia de síntomas e incapacidad, muchas no creen tener VIH y consideran el diagnóstico una mentira o lo relacionan con "daño", estas ideas las disuaden de aceptar las indicaciones médicas, afectando la credibilidad y confianza hacia los servicios de salud. Además, piensan que sus hijos inevitablemente nacerán enfermos y morirán pronto, por lo que consideran la cesárea y el cuidado del niño un esfuerzo vano. A estas barreras se suman las diferencias de idioma y lejanía de los establecimientos de salud; también el temor al juicio y condena moral de su comunidad. Conclusiones Las medidas para la prevención de la TMI parecen extrañas para las costumbres, valores y creencias de las gestantes/madres, por lo que no son comprendidas ni aceptadas, resultando ineficaces y perjudicando la relación con el personal de salud. Se necesita una mejor comprensión de la cultura y el diseño de intervenciones adecuadas a ésta población.

ABSTRACT Objectives To identify the barriers that limit compliance with the prevention of mother-to-child transmission (PMTCT) of HIV measures in two indigenous communities of the Amazon region of Peru. Materials and methods Qualitative study with a phenomenological approach. Semi-structured interviews were conducted with pregnant women and mothers of children younger than 1 year of the awajún and wampis indigenous communities diagnosed with HIV in the period 2014-2015. Results The study sample included 15 of 29 eligible women and 87% were Awajún. Limitations and possible negative effects were observed in cases in which sanitary measures for PMTCT were imposed. Considering their knowledge of diseases, including the presence of symptoms and disabilities, many women from these communities do not believe they are infected with HIV and consider the diagnosis a lie or relate the diagnosis to harm, and these beliefs limit their compliance with medical indications and decrease their trust in health services. In addition, the women believe that their children will inevitably be born sick and will die soon, and thus consider cesarean sections and child care a futile effort. Other factors influencing the successful implementation of PMTCT measures include language barriers, remoteness of health centers, and the fear of judgment and moral condemnation by the local community. Conclusions PMTCT measures challenge the customs, values, and beliefs of pregnant women and mothers in the Awajún and Wampis indigenous communities, and thus these measures are not understood or accepted, jeopardizing the relationship of the mothers with health personnel. Therefore, cultural factors and interventions appropriate to this population must be better understood.

[Access barriers to comprehensive care for people affected by tuberculosis and human immunodeficiency virus coinfection in Peru, 2010-2015]. / Barreras para el acceso a la atención integral de las personas afectadas por la coinfección por tuberculosis y virus de inmunodeficiencia humana en Perú, 2010­2015.

OBJECTIVE: Identify the programmatic barriers that hinder access to comprehensive care of patients with tuberculosis and human immunodeficiency virus (TB/HIV) coinfection. METHODS: This is a mixed-method study. Qualitative research was conducted via in-depth interviews with key actors and the quantitative component involved cross-sectional descriptive analysis of programmatic data from 2010-2015 on tuberculosis and HIV programs at health facilities in the cities of Lima and Iquitos. RESULTS: Twenty-two key actors in seven establishments were interviewed. The identified barriers were: little or no coordination between tuberculosis and HIV teams, separate management of tuberculosis and HIV cases at different levels of care, insufficient financing, limited or poorly trained human resources, and lack of an integrated information system. It was found that HIV screening in TB patients increased (from 18.8% in 2011 to 95.2% in 2015), isoniazid coverage of HIV patients declined (from 62% to 9%), and the proportion of deaths among TB/HIV coinfection cases averaged 20%. CONCLUSIONS: There is poor coordination between HIV and TB health strategies. Management of TB/HIV coinfection is fragmented into different levels of care, which has an impact on comprehensive patient care. As a result of this research, a technical document was prepared to establish joint procedures that should be implemented to improve comprehensive care of TB/HIV coinfection.
