Long-term evolution in liver disease markers and immune and lipid profiles in vertically HIV/HCV-coinfected youths with sustained viral response after direct-acting antivirals therapy.

This study aimed to analyse the long-term effect of direct-acting antivirals (DAAs) in vertically acquired HIV/HCV-coinfected youths. We performed a multicentre, longitudinal and observational study within the Spanish Cohort of HIV-infected children and adolescents and vertically HIV-infected patients transferred to Adult Units (CoRISpe-FARO). We included HIV/HCV-coinfected youths (n = 24) that received DAAs between 2015 and 2017 with successful sustained viral response (SVR) with a subsequent follow-up of at least three years. Long-term evolution in liver disease severity and haematologic markers, lipid and immune profiles after SVR were assessed. Study times were the start date of DAAs treatment (baseline, T0) and 1, 2, 3, 4 and 5 years after SVR (T1, T2, T3, T4 and T5, respectively). We observed global improvements in liver function data that persist over time and a favourable haematologic and immune outcome at the long-term including a constant augment in leucocytes, neutrophils, neutrophils to lymphocytes ratio (NLR) and CD4/CD8 ratio over-time. Regarding the lipid profile, we found a significant increase in total cholesterol T2, total cholesterol/high-density lipoprotein (HDL) ratio at T4, triglycerides at T5, low-density lipoprotein (LDL) over time, and a decrease in HDL in all patients but with marked higher levels in the subgroup receiving anti-HIV Protease Inhibitor (PI)-based regimens. Comparisons of vertically HIV/HCV-coinfected youths after SVR at 3-year follow-up and a control group of vertically HIV-monoinfected youths never infected by HCV showed no significant differences in most variables analysed, suggesting a possible normalization in all parameters.

Diferencias epidemiológicas y de mortalidad entre hombres y mujeres con infección por VIH en la cohorte CoRIS entre los años 2004 y 2014 / Differences in epidemiology and mortality between men and women with HIV infection in the CoRIS cohort from 2004 to 2014

Objetivos: Analizar en la cohorte CoRIS las diferencias epidemiológicas y en la mortalidad entre mujeres y hombres que viven con VIH y su evolución en el tiempo. Métodos: Se compararon las variables de interés entre mujeres que viven con VIH y hombres que viven con VIH. Se realizó un análisis de tendencias usando la prueba de Mantel-Haenszel. Para estudiar la supervivencia se utilizaron las curvas de supervivencia de Kaplan Meier y un análisis de regresión de Cox. Resultados: Se incluyeron un total de 10.469 personas, de las cuales 1.742 (16,6%) eran mujeres. En el momento de inclusión en la cohorte las mujeres que viven con VIH con respecto a los hombres que viven con VIH tenían un mayor porcentaje de transmisiones por el uso de drogas intravenosas (UDI), coinfección por el virus de la hepatitisC (VHC), estadio de sida y origen extranjero. También presentaron una peor situación inmunovirológica y nivel de estudios. Estas diferencias se mantuvieron en el estudio de tendencias. En cuanto a la edad, las mujeres que se incluyeron en la cohorte fueron cada vez más mayores, y lo contrario sucedió con los hombres. En el análisis comparativo entre mujeres según su lugar de origen encontramos mujeres más mayores, con más transmisión por UDI y coinfección por VHC en el grupo de las mujeres que viven con VIH españolas; en cambio, la infección por sífilis fue más frecuente entre las nacidas fuera de España. No hubo grandes diferencias en relación con otras características, como el nivel de estudios o la situación de enfermedad. El sexo no fue un condicionante de supervivencia, y sí lo fueron factores que se asociaban más a las mujeres. Conclusiones: Las mujeres infectadas por el VIH se presentaron al diagnóstico con unas características epidemiológicas y asociadas a la infección por VIH que las hacen más vulnerables, y estas tendencias fueron acentuándose o no mejoraron durante los años de observación.(AU)

Introduction: This study sought to analyse differences in epidemiology and survival between women and men living with HIV in the CoRIS cohort and the course of their disease over a 10-year period. Methods: Variables of interest between women living with HIV and men living with HIV were compared. A trend analysis was performed using the Mantel-Haenszel test. Kaplan-Meier survival curves and a Cox regression analysis were used to study survival. Results: A total of 10,469 people were enrolled; of them, 1,742 (16.6%) were women. At the time of enrolment in the cohort, women living with HIV, compared to men living with HIV, had higher rates of transmission due to intravenous drug use (IDU), hepatitisC virus (HCV) coinfection, AIDS-stage disease and foreign origin. They also had a worse immunovirological status and a lower educational level. These differences were maintained in the trend study. Regarding age, the women included in the cohort were older whereas the men were younger. In the comparative analysis between women according to place of origin, we found that the group of Spanish women living with HIV featured older women with higher rates of IDU transmission and HCV coinfection, whereas the group of women living with HIV born outside of Spain featured women with higher rates of syphilis infection. There were no major differences in relation to other characteristics such as educational level or disease status. Although sex was not a determinant of survival, conditions more prevalent in women were determinants of survival. Conclusions: HIV-infected women presented at diagnosis with certain epidemiological and HIV-associated characteristics that made them more vulnerable. These trends became more marked or did not improve during the years of observation.(AU)

Differences in epidemiology and mortality between men and women with HIV infection in the CoRIS cohort from 2004 to 2014.

INTRODUCTION: This study sought to analyse differences in epidemiology and survival between women and men living with HIV (WLHIV and MLHIV) in the CoRIS cohort and the course of their disease over a 10-year period. METHODS: Variables of interest between WLHIV and MLHIV were compared. A trend analysis was performed using the Mantel-Haenszel test. Kaplan-Meier survival curves and a Cox regression analysis were used to study survival. RESULTS: A total of 10,469 people were enrolled; of them, 1,742 (16.6%) were women. At the time of enrolment in the cohort, WLHIV, compared to MLHIV, had higher rates of transmission due to intravenous drug use (IDU), hepatitis C virus (HCV) coinfection, AIDS-stage disease and foreign origin. They also had a worse immunovirological status and a lower educational level. These differences were maintained in the trend study. Regarding age, the women included in the cohort were older whereas the men were younger. In the comparative analysis between women according to place of origin, we found that the group of Spanish WLHIV featured older women with higher rates of IDU transmission and HCV coinfection, whereas the group of WLHIV born outside of Spain featured women with higher rates of syphilis infection. There were no major differences in relation to other characteristics such as educational level or disease status. Although sex was not a determinant of survival, conditions more prevalent in women were determinants of survival. CONCLUSIONS: HIV-infected women presented at diagnosis with certain epidemiological and HIV-associated characteristics that made them more vulnerable. These trends became more marked or did not improve during the years of observation.

Late HIV diagnosis among immigrants in Spain vs. native-born Spaniards, 2010-15.

BACKGROUND: In 2012, the central government of Spain enacted Royal Decree-Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012, which abolished universal healthcare coverage, thus limiting access to care for undocumented immigrants. Free health care was also no longer granted to anyone who has never been employed. In this context, this study investigated the prevalence of late HIV diagnoses (LHDs) among immigrants living in Spain vs. native-born Spaniards. METHODS: Data (n = 5943) from the 2010 to 2015 Cohort of the Spanish AIDs Research Network were used, including HIV-positive and antiretroviral therapy (ART)-naïve patients throughout Spain. Multivariate logistic models were fitted to compare the prevalence of LHD among the groups, adjusting for covariates. RESULTS: The prevalence of LHD in the total sample was 39.5%. Compared with native-born Spaniards (n = 4445), immigrants (n = 1488) were more likely to have LHD (37.4% vs. 45.7%, respectively; P < 0.001). Multivariate analysis showed that the prevalence ratio of LHD among immigrants vs. native-born Spaniards was 1.15 [95% confidence interval (CI), 1.02-1.28], after adjusting for covariates. This disparity widened from 2010 to 2011 (APR = 1.14, 95% CI, 1.02-1.29) to 2012-15 (APR = 1.28, 95% CI, 1.17-1.39), although the change was not statistically significant. CONCLUSIONS: Immigrants in Spain had a higher risk of LHD compared with native-born counterparts. LHD is an important healthcare marker due to the positive benefits of early HIV diagnosis, including prevention, improvements in health outcomes and decreases in overall cost of treatment. More research is needed on the causes of the disparity and potential social and policy interventions to reduce the prevalence of LHD among immigrants.

COVID-19 in hospitalized HIV-positive and HIV-negative patients: A matched study.

OBJECTIVES: We compared the characteristics and clinical outcomes of hospitalized individuals with COVID-19 with [people with HIV (PWH)] and without (non-PWH) HIV co-infection in Spain during the first wave of the pandemic. METHODS: This was a retrospective matched cohort study. People with HIV were identified by reviewing clinical records and laboratory registries of 10 922 patients in active-follow-up within the Spanish HIV Research Network (CoRIS) up to 30 June 2020. Each hospitalized PWH was matched with five non-PWH of the same age and sex randomly selected from COVID-19@Spain, a multicentre cohort of 4035 patients hospitalized with confirmed COVID-19. The main outcome was all-cause in-hospital mortality. RESULTS: Forty-five PWH with PCR-confirmed COVID-19 were identified in CoRIS, 21 of whom were hospitalized. A total of 105 age/sex-matched controls were selected from the COVID-19@Spain cohort. The median age in both groups was 53 (Q1-Q3, 46-56) years, and 90.5% were men. In PWH, 19.1% were injecting drug users, 95.2% were on antiretroviral therapy, 94.4% had HIV-RNA < 50 copies/mL, and the median (Q1-Q3) CD4 count was 595 (349-798) cells/µL. No statistically significant differences were found between PWH and non-PWH in number of comorbidities, presenting signs and symptoms, laboratory parameters, radiology findings and severity scores on admission. Corticosteroids were administered to 33.3% and 27.4% of PWH and non-PWH, respectively (P = 0.580). Deaths during admission were documented in two (9.5%) PWH and 12 (11.4%) non-PWH (P = 0.800). CONCLUSIONS: Our findings suggest that well-controlled HIV infection does not modify the clinical presentation or worsen clinical outcomes of COVID-19 hospitalization.

Mortality in Perinatally HIV-infected Adolescents After Transition to Adult Care in Spain.

INTRODUCTION: After the introduction of combination antiretroviral treatment, (ART) mortality in HIV-infected patients has dramatically decreased. However, it is still high in patients at risk, as adolescents transitioning to adult care (AC) without virologic control. The aim of this study was to characterize mortality and comorbidities of perinatally infected HIV (PHIV) patients after transition to AC. METHODS: A multicenter retrospective study from patients included in the CoRISpe-FARO Spanish cohort was conducted. PHIV patients who died after transition to AC between 2009 and 2019 were included. Clinical, immunovirologic characteristics, treatments received, comorbidities and causes of death were described. RESULTS: Among 401 PHIV patients, 14 died (3.5%). All were Spanish, 11/14 (78.6%) women. The median age at diagnosis was 1.5 years (interquartile range [IQR] 0.5-3.9), at transfer to AC was 18 years [16.1-19.9] and at death was 25.8 years [23.6-27.1]. In pediatric units [pediatric care (PC)], CD4+ nadir was 85 cells/µL [IQR 9.7-248.5] and 6/14 patients were classified as C-clinical stage. During AC, all patients were on C-clinical stage and CD4+ nadir dropped to 11.5 cells/µL [4.5-43.3]. cART adherence was extremely poor: in PC, 8/14 patients registered voluntary treatment interruptions; only one had undetectable VL at transition. In AC, 12/14 patients stopped treatment 2 or more periods of time. All deaths were related to advanced HIV disease. Mental health disorders were observed in 7/14 (50%). Main complications described: recurrent bacterial infections (57.1%), wasting syndrome (42.9%), esophageal candidiasis (28.6%) and Pneumocystis jirovecii pneumonia (28.6%). Four women had 11 pregnancies; 5 children were born (none infected). CONCLUSIONS: Young adults PHIV infected who transition to AC without virologic suppression or proven ability to adhere to ART are at high risk of mortality. Mortality was noted as a consequence of advanced HIV disease, frequent mental health problems and poor adherence to ART.

These trends became more marked or did not improve during the years of observation.

Increased rate of FEV1 decline in HIV patients despite effective treatment with HAART.

INTRODUCTION: Previous studies have reported that the rate of FEV1 decline over time is increased in HIV patients but the mechanisms underlying this observation are unclear. Since current HIV treatment with Highly Active Antiretroviral Therapy (HAART) results in very good immune-viral control, we hypothesized that HAART should normalize the elevated rate of FEV1 decline previously reported in HIV patients if it was somehow related to the immune alterations caused by HIV, particularly in never smokers or quitters, since smoking is a well established risk factor for accelerated FEV1 decline in the general population. METHODS: We explored this hypothesis in a prospectively recruited cohort of 188 HIV (smoker and non-smoker) patients treated with HAART in Palma de Mallorca (Spain) and followed-up for 6 years. The cross-sectional characteristics of this cohort have been published elsewhere. RESULTS: We found that: (1) HAART resulted in good immune-viral control; (2) the rate of FEV1 decline remained abnormally elevated, even in non-smokers and quitters; and, (3) alcohol abuse during follow-up was related to FEV1 decline in these patients. DISCUSSION: Despite adequate immune-viral control by HAART, lung function decline remains increased in most HIV patients, even in non-smokers and quitters. Alcohol abuse is a preventable risk factor to decrease the accelerated FEV1 decline in this population.

Interatrial blocks prevalence and risk factors for human immunodeficiency virus-infected persons.

BACKGROUND: Interatrial blocks are considered a new important risk factor for atrial fibrillation and cerebrovascular events. Their prevalence and clinical implications have been reported in general population and several subgroups of patients but no data from HIV-infected populations, with a non-negligible prevalence of atrial fibrillation, has been previously reported. METHODS: We conducted a cross-sectional study in a previously enrolled cohort of randomly selected middle-aged HIV-infected patients who attended our hospital and were clinically stable. Patients underwent both a 12-lead rest electrocardiogram and clinical questionnaires while epidemiological, clinical and HIV-related variables were obtained from electronic medical records and interviews with the patients. Electrocardiograms were then analyzed and codified using a standardized form by two trained members of the research team who were blinded to clinical variables. RESULTS: We obtained electrocardiograms from 204 patients with a mean age of 55.22 years, 39 patients (19.12%) presented an interatrial block, 9 (4.41%) advanced and 30 (14.71%) partial. Patients with interatrial block had a lower nadir lymphocyte CD4 count (124 vs 198 cells, p = 0.02) while advanced interatrial blocks were associated to older age (62.16 vs. 54.95 years, p = 0.046) and hypertension (77.8% vs. 32.3%, p = 0.009). We did not find differences regarding baseline CD4 lymphocyte count or CD4/CD8 lymphocyte ratio. Clinical variables and functional capacity among patients with or without interatrial block were similar. CONCLUSIONS: In a cohort of clinically stable HIV infected patients the prevalence of interatrial blocks, specially advanced, is high and associated to previously known factors (age, hypertension) and novel ones (nadir CD4 lymphocyte count).

Effectiveness and safety of dual therapy with rilpivirine and boosted darunavir in treatment-experienced patients with advanced HIV infection: a preliminary 24 week analysis (RIDAR study).

BACKGROUND: The objective was to analyze the effectiveness and safety of dual therapy with rilpivirine plus boosted-darunavir (RPV + bDRV) in real-life patients. METHODS: Observational, retrospective, multi-center study in HIV+ patients who had received RPV + bDRV for 24 weeks to optimize/simplify their previous antiretroviral treatment. We determined the percentage of patients without virologic failure (2 consecutive viral loads > 50 copies/mL) at 24 weeks of treatment. RESULTS: The study included 161 patients from 15 hospitals with median age of 49 years; 29.3% had previous AIDS stage and median CD4+ lymphocyte nadir of 170 cells/uL. They had been diagnosed with HIV for a median of 17 years and had received 14 years of ART, with five previous treatment combinations, and 36.6% had a history of virological failure. The reasons for the switch were simplification/optimization (49.7%), toxicity/intolerance (17.4%), or inadequate effectiveness of previous ART (10.6%). Baseline VL of 50-1000 copies/mL was recorded in 25.5% of the patients. In the"intention-to-treat" analysis at 24 weeks, 87.6% of 161 patients continued the study treatment without virologic failure criteria. In the "on treatment" analysis (excluding patients who discontinued treatment with dual therapy for any reason other than virologic failure) the efficacy was 94.6% (141/149 patients). CONCLUSIONS: Dual therapy with RPV + DRVb proved to be effective and safe in patients with advanced HIV infection, long exposure to ART, low CD4 nadir, previous virologic failure, and/or history of ineffective ART.

Raltegravir plus abacavir/lamivudine in virologically suppressed HIV-1-infected patients: 48-week results of the KIRAL study.

BACKGROUND: Long-term combination antiretroviral therapy often results in toxicity/tolerability problems, which are one of the main reasons for switching treatment. Despite the favorable profile of raltegravir (RAL), data on its combination with abacavir/lamivudine (ABC/3TC) are scarce. Based on clinical data, we evaluated this regimen as a switching strategy. DESIGN: Multicenter, non-controlled, retrospective study including all virologically suppressed HIV-1-infected patients who had switched to RAL+ABC/3TC. METHODS: We evaluated effectiveness (defined as maintenance of HIV-1-RNA <50 copies/mL at 48 weeks) safety, tolerability, laboratory data, and CD4+ count at week 48 of this switching strategy. RESULTS: The study population comprised 467 patients. Median age was 49 years (IQR: 45-53). Males accounted for 75.4%. Median CD4+ count at baseline was 580 cells/µL (IQR, 409). The main reasons for switching were toxicity/tolerability problems (197; 42.2%) and physician's criteria (133; 28.5%). At week 48, HIV-1 RNA remained at <50 copies/mL in 371/380 (97.6%; 95%CI: 96.4-99.0) when non-virological failure was censured. Virological failure was recorded in 1.9% patients and treatment failure in 20.5% of patients (96/467 [95%CI, 16.9-24.2]). The main reasons for treatment failure included switch to fixed-dose combination regimens (31; 6.6%), toxicity/poor tolerability (27; 5.8%), and physician's decision (17; 3.6%). A total of 73 adverse events were detected in 64 patients (13.7%). These resolved in 43 patients (67.2%). Of the 33 cases related or likely related to treatment, 30 were Grade-1 (90.9%). CD4+ count and renal, hepatic, and lipid profiles remained clinically stable over the 48 weeks. CONCLUSIONS: Our findings suggest that RAL+ABC/3TC could be an effective, safe/tolerable, and low-toxicity option for virologically suppressed HIV-1-infected patients.

Pharmacogenetics of efficacy and safety of HCV treatment in HCV-HIV coinfected patients: significant associations with IL28B and SOCS3 gene variants.

BACKGROUND AND AIMS: This was a safety and efficacy pharmacogenetic study of a previously performed randomized trial which compared the effectiveness of treatment of hepatitis C virus infection with pegylated interferon alpha (pegIFNα) 2a vs. 2b, both with ribavirin, for 48 weeks, in HCV-HIV coinfected patients. METHODS: The study groups were made of 99 patients (efficacy pharmacogenetic substudy) and of 114 patients (safety pharmacogenetic substudy). Polymorphisms in the following candidate genes IL28B, IL6, IL10, TNFα, IFNγ, CCL5, MxA, OAS1, SOCS3, CTLA4 and ITPA were assessed. Genotyping was carried out using Sequenom iPLEX-Gold, a single-base extension polymerase chain reaction. Efficacy end-points assessed were: rapid, early and sustained virological response (RVR, EVR and SVR, respectively). Safety end-points assessed were: anemia, neutropenia, thrombocytopenia, flu-like syndrome, gastrointestinal disturbances and depression. Chi square test, Student's T test, Mann-Whitney U test and logistic regression were used for statistic analyses. RESULTS: As efficacy is concerned, IL28B and CTLA4 gene polymorphisms were associated with RVR (p<0.05 for both comparisons). Nevertheless, only polymorphism in the IL28B gene was associated with SVR (p = 0.004). In the multivariate analysis, the only gene independently associated with SVR was IL28B (OR 2.61, 95%CI 1.2-5.6, p = 0.01). With respect to safety, there were no significant associations between flu-like syndrome or depression and the genetic variants studied. Gastrointestinal disturbances were associated with ITPA gene polymorphism (p = 0.04). Anemia was associated with OAS1 and CTLA4 gene polymorphisms (p = 0.049 and p = 0.045, respectively), neutropenia and thromobocytopenia were associated with SOCS3 gene polymorphism (p = 0.02 and p = 0.002, respectively). In the multivariate analysis, the associations of the SOCS3 gene polymorphism with neutropenia (OR 0.26, 95%CI 0.09-0.75, p = 0.01) and thrombocytopenia (OR 0.07, 95%CI 0.008-0.57, p = 0.01) remained significant. CONCLUSIONS: In HCV-HIV coinfected patients treated with PegIFNα and ribavirin, SVR is associated with IL28B rs8099917 polymorphism. HCV treatment-induced neutropenia and thrombocytopenia are associated with SOCS3 rs4969170 polymorphism.

Effectiveness of polysaccharide pneumococcal vaccine in HIV-infected patients: a case-control study.

BACKGROUND: Polysaccharide pneumococcal vaccine (PPV) is recommended among human immunodeficiency virus (HIV)-infected patients, although its effect in reducing the incidence of pneumonia or invasive pneumococcal disease is not well established. Our objective was to determine the effectiveness of 23-valent PPV in HIV-infected adults and the risk factors for pneumococcal pneumonia or invasive pneumococcal disease. METHODS: We performed a retrospective case-control study in 4 Spanish hospitals for the period from January 1995 through December 2005 using the HIV database from each hospital to identify case patients with Streptococcus pneumoniae disease and control subjects without a history of pneumococcal infection. RESULTS: A total of 184 case patients and 552 control subjects were identified. The factors associated with pneumococcal disease in bivariate analysis were active injection drug use (odds ratio [OR], 3.33; 95% confidence interval [CI], 2-5.55), alcoholism (OR, 3.03; 95% CI, 1.86-4.91), chronic obstructive pulmonary disease (OR, 2.58; 95% CI, 1.3-5.1), cirrhosis (OR, 6.05; 95% CI, 3.2-11.4), antiretroviral therapy (OR, 0.23; 95% CI, 0.16-0.32), trimethoprim-sulfamethoxazole prophylaxis (OR, 0.66; 95% CI, 0.45-0.97), viral load <5000 copies/mL (OR, 0.38; 95% CI, 0.26-0.54), and previous PPV (OR, 0.39; 95% CI, 0.24-0.65). Risk factors for pneumococcal disease in multivariate analysis were cirrhosis (OR, 5.64; 95% CI, 2.53-12.53), chronic obstructive pulmonary disease (OR, 2.90; 95% CI, 1.21-6.94), and alcoholism (OR, 2.15; 95% CI, 1.11-4.19), whereas protective factors were receipt of antiretroviral therapy (OR, 0.23; 95% CI, 0.14-0.36) and receipt of pneumococcal vaccine (OR, 0.44; 95% CI, 0.22-0.88), even in patients with CD4 lymphocyte counts <200 cells/microL. CONCLUSIONS: Antiretroviral therapy and PPV have a significant, independent protective effect against pneumococcal disease, regardless of CD4 lymphocyte count; thus, all patients with HIV infection should be vaccinated with PPV to prevent pneumococcal disease.
