Factors associated with social deprivation among older persons living with HIV.

Aging persons living with HIV may develop multiple health problems, including comorbidities, and altered physical and mental health, earlier than non-infected people. They may also experience social deprivation. We assessed the prevalence of social deprivation and its relationship with health indicators in older persons living with HIV. An 18-month, multicenter, cross-sectional study was carried out between 2013 and 2014 focusing on patients ≥50-years of age followed-up in 12 dedicated HIV medical hospital units located in the South of France and involved the VISAGE study group. Social deprivation was measured with the EPICES (Evaluation of Deprivation and Inequalities in Health Examination Centers) score (ES) and defined as ES ≥30.17. The following data were recorded: health indicators (gender, age, body mass index), comorbidities, frailty markers, socioeconomic, behavioral and age-related variables. Among 509 patients recruited, 494 completed the ES social deprivation evaluation. Mean age was 58.5 ± 7.0 years and 72.9% were male. The prevalence of social deprivation was 49.0%. Multivariable logistic regression analysis showed that higher social deprivation was significantly linked to alcohol consumption (OR = 4.07 [95%CI: 1.23-13.48]), risk of depression (OR = 3.59 [95%CI: 2.26-5.70]), chronic obstructive pulmonary disease (OR = 3.10 [95%CI: 1.36-7.09]), hepatitis C (OR = 1.96 [95%CI: 1.10-3.52]), and chronic pain (OR = 1.11 [95%CI: 1.01-1.21]). Social deprivation was not related to HIV status. Our study showed that not only did older patients with HIV suffer from social deprivation, but they also received little support from social workers. Physicians should be aware of this situation and should systematically evaluate social deprivation in order to provide comprehensive targeted care involving global, social, and psychological support to reduce the burden of social deprivation.

Safety and tolerability of immune checkpoint inhibitors in people with HIV infection and cancer: insights from the national prospective real-world OncoVIHAC ANRS CO24 cohort study.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have been a major advance in cancer management. However, we still lack prospective real-world data regarding their usage in people with HIV infection (PWH). METHODS: The ANRS CO24 OncoVIHAC study (NCT03354936) is an ongoing prospective observational cohort study in France of PWH with cancer treated with ICI. We assessed the incidence of grade ≥3 immune-related adverse events (irAEs). All grade ≥3 irAEs were reviewed by an event review. RESULTS: Between January 17, 2018, and December 05, 2023, 150 participants were recruited from 33 sites and 140 were included in this analysis. At the data cut-off date of December 05, 2023, the median follow-up was 9.2 months (IQR: 3.9-18.3), with a total of 126.2 person-years.Median age was 59 years (IQR: 54-64) and 111 (79.3%) were men. Median time since HIV diagnosis was 25 years (12-31), the median duration on antiretroviral (ARV) was 19.5 years (7.7-25.4), and the CD4 nadir was 117/µL (51-240). ICI regimens comprised anti-programmed cell death protein-1 (PD-1) for 111 (79.3%) participants, anti-programmed death-ligand 1 for 25 (17.9%), a combination of anti-PD-1 and anti-cytotoxic T-lymphocyte associated protein 4 for 3 (2.1%), and anti-PD-1 along with anti-vascular endothelial growth factor receptor for 1 (0.7%). The most frequent cancers were lung (n=65), head/neck (n=15), melanoma (n=12), liver (n=11) and Hodgkin's lymphoma (n=9).During follow-up, a total of 34 grade ≥3 irAEs occurred in 20 participants, leading to an incidence rate of 26.9 per 100 person-years. The Kaplan-Meier estimates of the proportion of participants with at least one episode of grade ≥3 irAEs were 13.8% at 6 months, 15.0% at 12 months and 18.7% at 18 months. One treatment-related death due to myocarditis was reported (0.7%). Multivariable analysis of cumulative incidence showed that participants with time since HIV diagnosis >17 years (incidence rate ratio (IRR)=4.66, p=0.002), with CD4<200 cells/µL (IRR=4.39, p<0.0001), with positive cytomegalovirus (CMV) serology (IRR=2.76, p=0.034), with history of cancer surgery (IRR=3.44, p=0.001) had a higher risk of incidence of grade ≥3 irAEs. CONCLUSION: This study showed that the incidence of a first episode of grade ≥3 irAE was 15.0% (95% CI: 9.6% to 22.9%) at 1 year and the cumulative incidence of all severe irAE episodes was 26.9 per 100 person-years. Low CD4 count, positive CMV serology, history of cancer surgery and a longer time since HIV diagnosis were associated with the occurrence of severe irAEs.

Despite being highly diverse, immunovirological status strongly correlates with clinical symptoms during primary HIV-1 infection: a cross-sectional study based on 674 patients enrolled in the ANRS CO 06 PRIMO cohort.

OBJECTIVES: To analyse immunovirological status during primary HIV-1 infection (PHI) according to contemporary clinical status and time since infection. METHODS: Plasma HIV-RNA and peripheral blood mononuclear cell (PBMC) HIV-DNA levels and CD4 cell counts were determined at enrolment in the ANRS PRIMO cohort. Time since infection was estimated based on both the number of antibodies on western blot at enrolment (0-1, 2-4 or > or =5 specific antibodies) and the estimated interval between infection and enrolment based on clinical and epidemiological features. Patients were classified according to the presence or absence of clinical symptoms at enrolment. RESULTS: Between 1996 and 2006, 674 patients were enrolled an estimated median of 47 days after infection. Median marker values were as follows: HIV-RNA 5.10 log(10) copies/mL (range <1.70-8.33); HIV-DNA 3.30 log(10) copies/10(6) PBMCs (<1.84-4.93); and 506 CD4 cells/mm(3) (40-1542). Median HIV-RNA and PBMC HIV-DNA levels were significantly higher in patients with 0 or 1 specific antibody (n = 71) than in patients with 2-4 (n = 228) or > or =5 antibodies (n = 375). Symptomatic patients had significantly higher HIV-RNA and PBMC HIV-DNA levels and lower CD4 cell counts. However, 10% of symptomatic patients recruited shortly after infection had favourable immunovirological status. CONCLUSIONS: Plasma HIV-RNA, PBMC HIV-DNA and CD4 cell count values were highly diverse and correlated strongly with clinical status during PHI. Early diagnosis was not always associated with severe PHI. Combining PBMC HIV-DNA with HIV-RNA, CD4 cell count and clinical symptoms would have allowed identification of 179 patients (26.5%) at high risk of rapid disease progression who did not meet current guidelines for early treatment initiation.

Lethal toxicities after capecitabine intake in a previously 5-FU-treated patient: why dose matters with dihydropryimidine dehydrogenase deficiency.

Dihydropryimidine dehydrogenase (DPD) deficiency is a pharmacogenetic syndrome associated with severe or lethal toxicities with oral capecitabine. Usually, patients with history of 5-FU-based therapy with no signs for life-threatening toxicities are considered as not DPD-deficient individuals who can be safely treated next with capecitabine if required. Here we describe the case of a woman originally treated with standard FEC100 protocol for metastatic breast cancer with little severe toxicities but grade-3 mucosities that were quickly resolved by symptomatic treatment. When switched to capecitabine + vinorelbine combo, extremely severe toxicities with fatal outcome were unexpectedly observed. Pharmacogenetic investigations were performed on cytidine deaminase and DPYD, and showed that this patient was heterozygous for the 2846A>T mutation on the DPYD gene. DPD phenotyping (i.e., uracil plasma levels >250 ng/ml, dihydrouracil/uracil ratio <0.5) confirmed that this patient was profoundly DPD deficient. Differences in fluoropyrimidine dosing between FEC100 (i.e., 500 mg/m2 5-FU) and capecitabine (i.e., 2250 mg daily) could explain why initial 5-FU-based protocol did not lead to life-threatening toxicities, whereas capecitabine rapidly triggered toxic death. Overall, this case report suggests that any toxicity, even when not life threatening, should be considered as a warning signal for possible underlying profound DPD deficiency syndrome, especially with low-dose protocols.

Real-World Efficacy of Daclatasvir and Sofosbuvir, With and Without Ribavirin, in HIV/HCV Coinfected Patients With Advanced Liver Disease in a French Early Access Cohort.

BACKGROUND: Efficacious, well-tolerated, direct antiviral agents have drastically changed the prognosis of hepatitis C virus (HCV) disease, but real-world data for oral treatments are limited in key populations such as HIV/HCV coinfection with advanced liver disease. Daclatasvir (DCV) efficacy and safety was assessed in the French "Autorisation Temporaire d'Utilisation" (ATU) program, providing DCV ahead of market authorization to patients with advanced HCV disease without other treatment options. METHODS: This was a subanalysis of HIV/HCV coinfected ATU patients treated with DCV plus sofosbuvir (SOF). Recommended duration was 24 weeks; addition of ribavirin (RBV) and/or shorter treatment was at the physician's discretion. The primary efficacy analysis was sustained virologic response at posttreatment week 12 (SVR12; modified intention-to-treat). Safety was assessed by spontaneous adverse event reporting. RESULTS: The efficacy population (N = 407) was mostly cirrhotic (72%, of whom 18% were decompensated), HCV treatment-experienced (82%), and infected with genotypes 1 (69%), 3 (12%), or 4 (19%). Median CD4 was 555 cells/mm; 95% had HIV RNA <50 copies/mL. Most (74%) were treated for 24 weeks; 14% received RBV. SVR12 was 92% overall (95% confidence interval: 88.6% to 94.0%); 90% (86.4% to 93.2%) in patients with cirrhosis; 95% (88.9% to 97.5%) in patients without cirrhosis. SVR12 was consistent across HCV genotypes and antiretroviral regimens. Among 617 patients with safety data, 7 discontinued for an adverse event and 10 died. CONCLUSIONS: DCV+SOF±RBV achieved high SVR12 and was well tolerated in this large real-world cohort of HIV/HCV coinfected patients with advanced liver disease.

Impact of IL28B on the treatment decision in naïve and experienced patients with genotype 1 and 4 chronic hepatitis C in real-life clinical practice: a prospective multicenter cohort.

BACKGROUND: The impact of the IL28B genotype on the real-life treatment decisions for patients infected with the hepatitis C virus (HCV) is unknown. OBJECTIVE: To prospectively analyze the impact of IL28B genotype in HCV genotype 1 (G1)- or 4 (G4)-infected patients using buccal epithelial cell samples in real-life clinical practices. PATIENTS AND METHODS: From October 2011 to March 2013, 1007 CHC patients were included among 127 French clinical centers. RESULTS: The IL28B CC, CT, and TT genotype distribution was 252 (25%), 576 (57%), and 177 (18%), respectively. The treatment decisions were recorded and matched with the initial intentions for 433 patients. Multivariate analysis on intention to start treatment showed that patients with HCV G4 were less likely to be intended to be treated than HCV G1 patients (odds ratio [OR]=0.43 [95% CI 0.19-0.97], P=0.04); similarly HIV-HCV coinfected patients were less likely to be intended to be treated than HCV monoinfected patients (OR=0.20 [0.09-0.41], P<.0001); conversely, F3-F4 patients were more likely to be intended to be treated than F0-F2 patients (OR=2.24 [1.29-3.89], P=0.004). Multivariate analysis on final decision to treat showed that Patients with F3-F4 were more likely to be treated than others (OR=2.06 [1.26-3.38], P=0.004). Conversely, although P-values are not significant, patients recruited in public hospitals tended to be less treated (OR=0.65 [0.40-1.04], P=0.069), similarly to HIV-HCV coinfected patients (OR=0.55 [0.28-1.11], P=0.095). CONCLUSION: Our study showed that the IL28B genotype is used for the management of HCV-infected patients. In the context of future treatments, IL28B genotyping may remain useful if it can be used to develop individualized treatment strategies, identifying patients who can be successfully treated with shorter, simpler, or cheaper regimens.

A single HIV-1 cluster and a skewed immune homeostasis drive the early spread of HIV among resting CD4+ cell subsets within one month post-infection.

Optimizing therapeutic strategies for an HIV cure requires better understanding the characteristics of early HIV-1 spread among resting CD4+ cells within the first month of primary HIV-1 infection (PHI). We studied the immune distribution, diversity, and inducibility of total HIV-DNA among the following cell subsets: monocytes, peripheral blood activated and resting CD4 T cells, long-lived (naive [TN] and central-memory [TCM]) and short-lived (transitional-memory [TTM] and effector-memory cells [TEM]) resting CD4+T cells from 12 acutely-infected individuals recruited at a median 36 days from infection. Cells were sorted for total HIV-DNA quantification, phylogenetic analysis and inducibility, all studied in relation to activation status and cell signaling. One month post-infection, a single CCR5-restricted viral cluster was massively distributed in all resting CD4+ subsets from 88% subjects, while one subject showed a slight diversity. High levels of total HIV-DNA were measured among TN (median 3.4 log copies/million cells), although 10-fold less (p = 0.0005) than in equally infected TCM (4.5), TTM (4.7) and TEM (4.6) cells. CD3-CD4+ monocytes harbored a low viral burden (median 2.3 log copies/million cells), unlike equally infected resting and activated CD4+ T cells (4.5 log copies/million cells). The skewed repartition of resting CD4 subsets influenced their contribution to the pool of resting infected CD4+T cells, two thirds of which consisted of short-lived TTM and TEM subsets, whereas long-lived TN and TCM subsets contributed the balance. Each resting CD4 subset produced HIV in vitro after stimulation with anti-CD3/anti-CD28+IL-2 with kinetics and magnitude varying according to subset differentiation, while IL-7 preferentially induced virus production from long-lived resting TN cells. In conclusion, within a month of infection, a clonal HIV-1 cluster is massively distributed among resting CD4 T-cell subsets with a flexible inducibility, suggesting that subset activation and skewed immune homeostasis determine the conditions of viral dissemination and early establishment of the HIV reservoir.

Hepatitis E virus in HIV-infected patients.

OBJECTIVES: Many cases of acute autochthonous hepatitic E virus (HEV) hepatitis have been reported in France, mainly from the south. Chronic HEV infection has recently been described in immunosuppressed patients. Although a potential risk of chronicity exists in HIV-infected patients, no survey has been conducted in this population. The aim of this study was to assess the sero-virological prevalence of HEV in French HIV-infected patients. METHODS: Two hundred and forty-five HIV-infected patients followed at two Infectious Diseases Departments (one in the south, one in the north) were included from January to March 2009. Sera were collected from all patients and tested using anti-HEV IgG and IgM kits. HEV RNA was systematically amplified in the ORF2 region with an in-house method. The IgG avidity index of all IgG-positive samples was determined. RESULTS: Three of the 133 southern patients showed both anti-HEV IgG and IgM positivities, along with cytolysis and biological cholestasis; HEV RNA was amplified in two of these cases, whereas a low IgG avidity index was observed in all three samples. Twelve of the 130 remaining southern patients (9%) showed anti-HEV IgG positivity. The serological prevalence in the 112 northern patients was 3%, which was significantly lower than in the southern patients (P=0.04). No case of acute hepatitis was reported in the north, whereas the prevalence of patients with biochemical liver abnormalities was similar in both areas (P=0.22). CONCLUSIONS: In France, HIV-infected patients are at risk of HEV infection with a serological north-to-south gradient. No case of chronic HEV infection was detected in this study.

Employment loss following HIV infection in the era of highly active antiretroviral therapies.

BACKGROUND: Employment is a major factor in maintaining living conditions of patients with chronic diseases. This study aimed to quantify the frequency and to identify the determinants of employment loss during the first years of HIV disease in the era of highly active antiretroviral therapies (HAART). METHODS: The French PRIMO multicentre prospective cohort of 319 patients enrolled during primary HIV-1 infection between 1996 and 2002. Employment loss was defined as moving from employment to inactivity between two visits. Characteristics associated with employment loss were assessed using generalized estimating equations. RESULTS: During a median follow-up time of 2.5 years, 56 employment losses occurred among 51 patients (18.0%). In multivariate analysis, female gender (adjusted odds ratio 3.1; 95% confidence interval 1.1-8.5), non-permanent job (3.8; 1.5-9.3) and poor accommodation (4.2; 1.6-11.2) constituted independent risk factors for employment loss; subjects with a high occupational position had a decreased risk of job loss. Moreover, an updated HIV viral load above 10 000 copies/ml either persistent (2.4; 1.1-5.0) or incident (3.7; 1.0-13.9) and hospitalization in the preceding 6 months (3.9; 1.6-9.7) constituted independent risk factors for employment loss, as tended to be a baseline CD4 cell count <350/mm(3) (1.9; 0.9-4.3) and chronic comorbidity (1.8; 0.9-3.6). CONCLUSIONS: In the HAART era, employment loss is frequent from the first months of HIV infection. Employment loss occurs especially in women and in patients with adverse socioeconomic conditions, severe HIV infection and/or comorbidity. Social interventions should seek to prevent HIV-infected patients from leaving their job from the earliest times of the disease.

Therapeutic drug monitoring of lopinavir/ritonavir given alone or with a non-nucleoside reverse transcriptase inhibitor.

AIMS: To evaluate the interindividual variability in the plasma concentrations of lopinavir in the context of routine monitoring with or without treatment with a non-nucleoside reverse transcriptase inhibitor and to assess the interaction between the coformulation of lopinavir/ritonavir and efavirenz or nevirapine. METHODS: Plasma trough and peak concentrations (C(trough), C(max)) of lopinavir from 182 HIV-1-infected patients were analysed by high-performace liquid chromatography. Three lopinavir/ritonavir regimens were assessed, namely (A) 400 mg lopinavir/100 mg ritonavir twice daily given alone (n = 125), (B) 400/100 mg twice daily together with a non-nucleoside reverse transcriptase inhibitor (n = 25), and (C) 533/133 mg twice daily together with a non-nucleoside reverse transcriptase inhibitor (n = 32). RESULTS: Median (ng ml(-1)) C(trough) and C(max) lopinavir (interquartile range, CV) were: (A) 4852 (3198-6891, 56%) and 8501 (6333-11 584, 41%), (B) 2979 (1704-5186, 74%) and 5612 (3362-11 704, 76%) and (C) 5082 (2696-7226, 74%) and 9757 (4883-12 963, 60%). Median C(trough) of lopinavir was lower in patients taking both efavirenz [P = 0.01, 95% confidence interval (CI) for difference between medians 343, 2713] and nevirapine (P = 0.019, 95% CI for difference between medians 354, 3681) compared with those taking lopinavir/ritonavir alone. A higher interindividual variability was observed when lopinavir/ritonavir was given with a non-nucleoside reverse transcriptase inhibitor. The risk of achieving a 'suboptimal'C(trough) of lopinavir (below a threshold of 3000 ng ml(-1)) was statistically higher in patients treated with a non-nucleoside reverse transcriptase inhibitor (P < 0.001, 95% CI for difference between percentages 8.8, 43.1%) compared with those receiving lopinavir/ritonavir alone. CONCLUSIONS: Our results confirmed the interaction between lopinavir and efavirenz, and also demonstrated a significant interaction between the former drug and nevirapine, resulting in lower C(trough) of lopinavir. The wide interpatient variability in this interaction suggests that therapeutic drug monitoring may be useful in optimizing the dose of lopinavir.
