Early Detection of Cancer and Precancerous Lesions in Persons with HIV through a Comprehensive Cancer Screening Protocol.

BACKGROUND: Non-AIDS defining malignancies present a growing challenge for persons with HIV (PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment. Acceptability of the procedure was additionally assessed. METHODS: Cross-sectional analysis of a comprehensive screening protocol to detect precancer and cancer. The readiness of healthcare providers to implement the protocol was evaluated using a validated 4-item survey. RESULTS: Among the 1430 enrolled PWH, 1172 underwent 3181 screening tests, with positive findings in 29.4% of cases, leading to further investigation in 20.7%. Adherence to the protocol was 84%, with HIV providers expressing high acceptability (97.1%), appropriateness (91.4%), and feasibility (77.1%). A total of 145 lesions were identified in 109 participants, including 60 precancerous lesions in 35 patients (3.0%), 9 early-stage cancers in 9 patients (0.8%), and 76 low-risk lesions in 65 subjects (5.5%). Adverse events related to screening occurred in 0.8% of participants, all mild. The overall prevalence of cancer precursors or early-stage cancer was 3.8% (95% CI, 2.74%-5.01%), with highest rates observed in individuals screened for anal and colorectal cancers. CONCLUSIONS: The baseline comprehensive cancer screening protocol of the IMPAC-Neo study successfully identified a significant proportion of PWH with precancerous lesions and early-stage cancer. High adherence rates and positive feedback from providers suggest effective implementation potential in real-world healthcare settings.

Rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide as first-line therapy in HIV infection. A prospective study.

INTRODUCTION: Rapid initiation of ART after HIV diagnosis is recommended for individual and public health benefits. However, certain clinical and ART-related considerations hinder immediate initiation of therapy. METHODS: An open-label, single-arm, single-centre 48-week prospective clinical trial involving ART-naïve HIV-diagnosed adults who started bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) within a week from the first hospital visit, before the availability of baseline laboratory and genotype results. The primary aim was to determine the proportion of people with at least one condition that would hinder immediate initiation of any recommended ART regimen other than BIC/FTC/TAF. Clinicaltrials.gov: NCT04416906. RESULTS: We included 100 participants: 79% men, 64% from Latin America, median age 32 years. According to European AIDS Clinical Society (EACS) and US Department of Health and Human Services 2023 guidelines, 11% (95%CI 6; 19) of participants had at least one condition that made any ART different from BIC/FTC/TAF less appropriate for a rapid ART strategy. Seventy-nine percent of the people started BIC/FTC/TAF within the first 48 hours of their first hospital visit. There were 16 early discontinuations (11 lost to follow-up). By week 48, 92% (95%CI 86; 98) of the participants of the ITT population with observed data achieved viral suppression. Eight grade 3-4 adverse events (AEs), five serious AEs and six ART-related AEs were identified. Adherence remained high. CONCLUSIONS: BIC/FTC/TAF is an optimal treatment for rapid initiation of ART. However, additional strategies to improve retention in care must be implemented.

Effectiveness, safety and discontinuation rates of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in people with HIV using real-world data: a systematic review and meta-analysis.

BACKGROUND: The use of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) is based on the results of robust clinical trials. OBJECTIVES: To assess the effectiveness and safety of BIC/FTC/TAF in treatment-naïve (TN) and treatment-experienced (TE) people with HIV using available real-world cohort studies. METHODS: Systematic review and meta-analysis of publications and communications identified via Boolean search in Medline, PubMed and Embase, and conference abstracts reporting retrospective real-world use of BIC/FTC/TAF, published until 31 January 2024. The primary endpoint was the proportion of TN and TE people with HIV with viral load (VL) < 50 copies/mL at 48 weeks while on treatment. RESULTS: Of the 38 identified publications and conference abstracts, for the present analysis we included 12 publications (comprising 792 TN and 6732 TE individuals). For the three publications including 507 TN participants reporting the primary outcome, VL suppression was 97% [95% confidence intervals (CI): 89-100]. For the nine publications including 4946 TE participants reporting the primary outcome, VL suppression was 95% (95% CI: 94-96), with suppression >93% in all studies. Total discontinuations at 48 weeks in TE individuals were 3% (95% CI: 2-5), 1% (95% CI: 0-2) due to side effects. A total of four publications with 151 TE individuals with previous presence of M184V substitution were identified, reporting a suppression rate at 48 weeks of 95% (95% CI: 88-100). CONCLUSIONS: Real-world studies demonstrate low discontinuation rates and high rates of virologic suppression in individuals treated with BIC/FTC/TAF, both TN and TE with and without previous detection of M184V substitution.

Toxic-Induced Encephalopathy Following Chemsex in a Young HIV-Positive Male: A Complex Case of Acute Cognitive Impairment with Anterograde Amnesia and Behavioral Alterations.

BACKGROUND: A broadened clinical spectrum of concomitant complications emerges among the escalating incidence of substance use, particularly within the 'chemsex' context. This case exemplifies the profound neurotoxic repercussions and neurological risk of chemsex in a young HIV-positive male and addresses the multifaceted challenges of such evolving paradigms in substance utilization. CLINICAL FINDING: After consuming cannabis, poppers, methamphetamine, and cocaine, a 28-year-old HIV-positive male exhibited significant neurological and cognitive impairment. The initial presentation included dysarthria and profound anterograde amnesia. Laboratory findings showed leukocytosis with a PCR of 3 mg/dl - elevated cerebrospinal fluid protein levels with no cells. Urine toxicology returned positive for cannabis and amphetamines. A brain CT scan revealed bilateral and symmetrical hippocampi and pale globes hypodensity, indicative of toxic-metabolic encephalopathy. MRI further identified lesions in the globus pallidus, cerebellum, and hippocampi. Following the detection of toxic encephalopathy, Initial neuropsychological was performed screening using the Montreal Cognitive Assessment (MoCA), which highlighted immediate memory deficits. An in-depth neuropsychological assessment conducted 3 weeks later included the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), the Rey Auditory Verbal Learning Test (RAVLT), and tests for visuospatial skills, motor functions, and memory recall. The evaluations revealed pronounced anterograde amnesia, persistent long-term memory inconsistencies, and notable executive function challenges, detailed in Table 1. CONCLUSIONS: The detailed analysis of this case underpins the severe neurological consequences that can manifest from heavy substance use. Comprehensive diagnostic evaluations, including neuroimaging and neuropsychological assessments, are crucial in elucidating the full spectrum of substance-induced cognitive impairments. There is an urgent need for enhanced public awareness and preventative measures, especially in the context of chemsex, to bring forth multifaceted health, social, and government implications that modern society must adeptly navigate.

Major cardiovascular events after COVID-19 in people with HIV.

OBJECTIVES: To assess the effect of COVID-19 on the postacute risk of cardiovascular events (CVEs) among people with HIV (PWH). METHODS: Population-based matched cohort, including all PWH ≥16 years in the Catalan PISCIS HIV cohort. We estimated the incidence rate of the first CVE after COVID-19, analysed it a composite outcome (2020-2022). We adjusted for baseline differences using inverse probability weighting and used competing risk analysis. RESULTS: We included 4199 PWH with and 14 004 PWH without COVID-19. The median follow-up was 243 days (interquartile range [IQR]: 93-455), 82% (14 941/18 203) were men, with a median age of 47 years. Overall, 211 PWH with COVID-19 and 621 without developed CVE, with an incidence rate of 70.2 and 56.8/1000 person-years, respectively. During COVID-19 infection, 7.6% (320/4199) required hospitalization and 0.6% (25/4199) intensive care unit admission, 97% (4079/4199) had CD4+T-cell ≥200 cells/µL, 90% (3791/4199) had HIV-RNA<50 copies/mL and 11.8% (496/4199) had previous CVE at baseline. The cumulative CVE incidence was higher among PWH after COVID-19 compared with PWH without COVID-19 during the first year (log-rank p=0.011). The multivariable analysis identified significantly increased CVE risk with age, heterosexual men, previous cardiovascular disease (CVD), and chronic kidney or liver disease. COVID-19 was associated with increased subsequent risk of CVE (adjusted hazard ratio 1.30 [95% CI, 1.09-1.55]), also when only including individuals without previous CVD (1.60 [95% CI, 1.11-2.29]) or nonhospitalized patients (1.34 [95% CI, 1.11-1.62]). DISCUSSION: COVID-19 was associated with a 30% increased risk of major CVE in PWH during the subsequent year, suggesting that COVID-19 should be considered an additional CVD risk in PWH in the short term.

Efficacy of Elbasvir/Grazoprevir in Early Chronic G1/G4 Hepatitis C infection in HIV/HCV co-infected patients with mild fibrosis / Eficacia de elbasvir/grazoprevir en la infección por hepatitis C crónica reciente G1/G4 en pacientes coinfectados por el VIH/VHC con fibrosis leve

Background: Acute hepatitis C virus (AHC) infection is increasingly common among HIV+ men who have sex with men (MSM). Until 2017, the guidelines recommended therapy with pegylated-interferon plus ribavirin with a mild sustained virological response (SVR). This prompted many patients to reject that treatment, at that time, waiting to be treated with better and safer options with new Direct-Acting-Antivirals (DAA). Objectives: Assess the efficacy and safety of Elbasvir/Grazoprevir to treat recent chronic hepatitis C infection, genotype 1 or 4, in HIV+ MSM patients. Methods: Prospective, open-labeled, two center, pilot study. SVR is analyzed for treatment with Elbasvir/Grazoprevir (8 weeks in GT1b or 12 in GT1a or GT4) in patients with a recent chronic HCV infection, defined as HCV infection lasting less than 4 years and mild liver fibrosis (liver stiffness <8kPa). Results: Forty-eight patients were included (May 2017–March 2018): 2 GT1b, 24 GT1a and 22 GT4. HCV-RNA>800000UI in 63% and medium liver stiffness 4.9kPa. The SVR was 98%, one patient failed due to poor adherence. 67% of patients had adverse effects, but only 16% treatment related. The most frequent side effects were gastrointestinal (19%), related with the central nervous system (18%), respiratory (16%) and systemic symptoms (15%).During one year of follow-up post-therapy, 4 AHC and 18 patients with sexually transmitted diseases (STD) were diagnosed. Conclusions: Treatment with Elbasvir/Grazoprevir in this scenario is highly effective and safe. Patients with risky sexual practices must remain linked to the medical care system to detect new STD and HCV reinfection.(AU)

Antecedentes: La infección aguda por el virus de la hepatitis C (HCA) es cada vez más frecuente entre los hombres VIH+ que mantienen relaciones sexuales con hombres (HSH). Hasta 2017, las directrices recomendaban el tratamiento con interferón pegilado más ribavirina con una respuesta virológica sostenida (RVS) leve. Esto llevó a muchos pacientes a rechazar dicho tratamiento en ese momento, a la espera de recibir tratamiento con opciones mejores y más seguras con los nuevos antivirales de acción directa (AAD). Objetivos: Evaluar la eficacia y la seguridad de elbasvir/grazoprevir para tratar la infección por hepatitis C crónica reciente, genotipo 1 o 4, en pacientes HSH VIH+. Métodos: Estudio preliminar, prospectivo, abierto y realizado en 2 centros. Se evalúa la RVS para el tratamiento con elbasvir/grazoprevir (8 semanas en GT1b o 12 en GT1a o GT4) en pacientes con una infección por VHC crónica reciente, definida como una infección por VHC que dura menos de 4 años y fibrosis hepática leve (rigidez hepática <8kPa). Resultados: Se incluyeron 48 pacientes (mayo de 2017-marzo de 2018): 2 en GT1b, 24 en GT1a y 22 en GT4. ARN-VHC>800.000UI en el 63% y rigidez hepática media de 4,9Kpa. La RVS fue del 98%; un paciente fracasó debido a un cumplimiento terapéutico deficiente. El 67% de los pacientes presentó efectos adversos, pero solo el 16% estuvo relacionado con el tratamiento. Los efectos secundarios más frecuentes fueron síntomas gastrointestinales (19%), relacionados con el sistema nervioso central (18%), respiratorios (16%) y sistémicos (15%). Durante un año de seguimiento postratamiento se diagnosticaron 4 HCA y 18 pacientes con enfermedades de transmisión sexual (ETS). Conclusiones: El tratamiento con elbasvir/grazoprevir en este contexto es muy eficaz y seguro. Los pacientes con prácticas sexuales de riesgo deben permanecer vinculados al sistema de asistencia médica para detectar nuevas ETS y reinfecciones por VHC.(AU)

Brote epidémico de hepatitis aguda C en pacientes infectados por el virus de la inmunodeficiencia humana / Acute outbreak of hepatitis C in human immunodeficiency virus-infected patients

INTRODUCCIÓN: Estudios recientes confirman un aumento de la incidencia de infección aguda por el virus de la hepatitis C (HAC) en hombres que tienen sexo con hombres (HSH) infectados o no por el VIH. El tratamiento temprano con interferón-alfa, solo o asociado a ribavirina, reduce significativamente el riesgo de evolución a la cronicidad. MÉTODOS: Estudio retrospectivo que incluye todos los pacientes VIH diagnosticados de HAC en nuestro centro desde junio del 2003 a marzo del 2013, definida la HAC por la seroconversión de anticuerpos contra el VHC y la detección de ARN-VHC sérico. RESULTADOS: Se diagnosticaron 93 episodios de HAC en 89 pacientes. Excepto en 3 casos todos eran HSH con antecedentes de prácticas sexuales de riesgo. Treinta y 7 (40%) pacientes presentaban otra enfermedad de transmisión sexual asociada. El 29% (27) presentaron algún síntoma sugestivo de HAC. El genotipo 4 del VHC fue el más frecuente (41%), seguido del genotipo 1. En 70 casos se inició tratamiento con interferón-alfa y ribavirina ajustada a peso. En la actualidad 46 han finalizado el tratamiento y el seguimiento, alcanzando 26 de ellos (56,5%) una respuesta viral sostenida. CONCLUSIONES: La incidencia de HAC en los pacientes VIH HSH de nuestro centro ha aumentado de forma exponencial en los últimos años, siendo la transmisión sexual la vía principal de infección. El tratamiento precoz con interferón-alfa y ribavirina consigue una respuesta moderada en estos pacientes

BACKGROUND: Recent studies suggest an increased incidence of acute infection with hepatitis C virus (AHC) in men who have sex with men (MSM) co-infected with HIV. Early treatment with interferon-alpha, alone or in combination with ribavirin, significantly reduces the risk of chronic evolution. METHODS: This retrospective study includes all HIV patients with AHC in our centre from 2003 to March 2013. AHC was defined by seroconversion of HCV antibodies and detection of serum HCV RNA.RESULTS: 93 episodes of AHC were diagnosed in 89 patients. All but three were MSM with a history of unprotected sex. Thirty-seven (40%) patients had other associated sexually transmitted disease. The 29% (27) had any symptoms suggestive of AHC. HCV genotype 4 was the most common (41%), followed by genotype 1. Seventy patients started treatment with interferon-alfa and weight-adjusted ribavirin. Currently 46 have completed treatment and follow-up, reaching 26 of them (56.5%) sustained viral response. CONCLUSIONS: The incidence of AHC in HIV MSM patients from our centre has increased exponentially in recent years; sexual transmission remains the main route of infection. Early treatment with interferon-alpha and ribavirin achieved a moderate response in these patients
