Safety and immunogenicity of the quadrivalent human papillomavirus (qHPV) vaccine in HIV-positive Spanish men who have sex with men (MSM). AIDS Res Ther 2017; 14:34.

Abstract
Background Safety and immunogenicity of the quadrivalent human papillomavirus (qHPV) vaccine were evaluated in HIV-positive Spanish MSM. The prevalence of High Squamous Intraepithelial Lesions (HSIL) and genotypes of high-risk human papillomavirus (HR-HPV) were also determined, as well as risk factors associated with the presence of HR-HPV in anal mucosa. Methods This is a randomised, double blind, placebo-controlled trial of the quadrivalent HPV (qHPV) vaccine. The study enrolled from May 2012 to May 2014. Vaccine and placebo were administered at 0, 2 and 6 months (V1, V2, V3 clinical visits). Vaccine antibody titres were evaluated at 7 months. Cytology (Thin Prep® Pap Test), HPV PCR genotyping (Linear Array HPV Genotyping Test), and high-resolution anoscopy (Zeiss 150 fc© colposcope) were performed at V1. Results Patients (n = 162; mean age 37.9 years) were screened for inclusion; 14.2% had HSIL, 73.1% HR-HPV and 4.5% simultaneous infection with HPV16 and 18. Study participants (n = 129) were randomized to qHPV vaccine or placebo. The most common adverse event was injection-site pain predominating in the placebo group [the first dose (83.6% vs. 56.1%; p = 0.0001]; the second dose (87.8% vs. 98.4%; p = 0.0001); the third dose (67.7% vs. 91.9%; p = 0.0001). The vaccine did not influence either the viral load of HIV or the levels of CD4. Of those vaccinated, 76% had antibodies to HPV vs. 30.2% of those receiving placebo (p = 0.0001). In the multivariate analysis, Older age was associated with lower HR-HPV infection (RR 0.97; 95% CI 0.96–0.99), and risk factor were viral load of HIV >200 copies/µL (RR 1.42 95% CI 1.17–1.73) and early commencement of sexual activity (RR 1.35; 95% CI 1.001–1.811). Conclusions This trial showed significantly higher anti-HR-HPV antibody titres in vaccinated individuals than in unvaccinated controls. There were no serious adverse events attributable to the vaccine. In our cohort, 1 of every 7 patients had HSIL and the prevalence of combined infection by genotypes 16 and 18 was low. This suggests that patients could benefit from receiving qHPV vaccine. Older age was the main protective factor against HR-HPV infection, and non-suppressed HIV viremia was a risk factor.

Economic impact of optimising antiretroviral treatment in human immunodeficiency virus-infected adults with suppressed viral load in Spain, by implementing the grade A-1 evidence recommendations of the 2015 GESIDA/National AIDS Plan. Enferm Infecc Microbiol Clin 2017; 36:157-164.

Abstract
INTRODUCTION The objective of this study is to estimate the economic impact associated with the optimisation of triple antiretroviral treatment (ART) in patients with undetectable viral load according to the recommendations from the GeSIDA/PNS (2015) Consensus and their applicability in the Spanish clinical practice. METHODS A pharmacoeconomic model was developed based on data from a National Hospital Prescription Survey on ART (2014) and the A-I evidence recommendations for the optimisation of ART from the GeSIDA/PNS (2015) consensus. The optimisation model took into account the willingness to optimise a particular regimen and other assumptions, and the results were validated by an expert panel in HIV infection (Infectious Disease Specialists and Hospital Pharmacists). The analysis was conducted from the NHS perspective, considering the annual wholesale price and accounting for deductions stated in the RD-Law 8/2010 and the VAT. RESULTS The expert panel selected six optimisation strategies, and estimated that 10,863 (13.4%) of the 80,859 patients in Spain currently on triple ART, would be candidates to optimise their ART, leading to savings of €15.9M/year (2.4% of total triple ART drug cost). The most feasible strategies (>40% of patients candidates for optimisation, n=4,556) would be optimisations to ATV/r+3TC therapy. These would produce savings between €653 and €4,797 per patient per year depending on baseline triple ART. CONCLUSION Implementation of the main optimisation strategies recommended in the GeSIDA/PNS (2015) Consensus into Spanish clinical practice would lead to considerable savings, especially those based in dual therapy with ATV/r+3TC, thus contributing to the control of pharmaceutical expenditure and NHS sustainability.

Abstract
OBJECTIVES Maraviroc (MVC) is a suitable drug for aviraemic subjects on antiretroviral treatment (ART) developing toxicity. Its prescription requires prior tropism testing. It is unknown if proviral DNA genotypic tropism testing is reliable for guiding MVC initiation in aviraemic subjects, so this study was carried out to address this issue. METHODS PROTEST was a phase 4, prospective, single-arm clinical trial carried out in 24 HIV care centres in Spain. MVC-naïve HIV-1-infected patients with HIV-1 RNA < 50 copies/mL on stable ART during the previous 6 months who required an ART change because of toxicity and who had R5 HIV, as determined by proviral DNA genotypic tropism testing, initiated MVC with two nucleoside reverse transcriptase inhibitors (NRTIs) and were followed for 48 weeks. Virological failure was defined as two consecutive viral load measurements > 50 copies/mL. RESULTS Tropism results were available for 141 of 175 (80.6%) subjects screened: 60% had R5 and 85% of these (n = 74) were finally included in the study. Previous ART included protease inhibitors (PIs) in 62% of subjects, nonnucleoside reverse transcriptase inhibitors (NNRTIs) in 36%, and integrase inhibitors (INIs) in 2%. Main reasons for treatment change were dyslipidaemia (42%), gastrointestinal symptoms (22%) and liver toxicity (15%). MVC was given alongside tenofovir (TDF)/emtricitabine (FTC) (54%) and abacavir (ABC)/lamivudine (3TC) (40%) in most patients. Eighty-four per cent of patients maintained a viral load < 50 copies/mL to week 48, whereas 16% discontinued treatment: two withdrew informed consent, one had an R5 to X4 shift between screening and baseline, one was lost to follow-up, one developed an adverse event (rash), two died from non-study-related causes, and five developed protocol-defined virological failure. CONCLUSIONS Initiation of MVC plus two NRTIs in aviraemic subjects based on genotypic tropism testing of proviral HIV-1 DNA is associated with low rates of virological failure for up to 1 year.

Abstract
BACKGROUND Since 1982, HIV-1 epidemics have evolved to different scenarios in terms of transmission routes, subtype distribution and characteristics of transmission clusters. We investigated the evolutionary history of HIV-1 subtype B in south Spain. PATIENTS & METHODS We studied all newly diagnosed HIV-1 subtype B patients in East Andalusia during the 2005-2012 period. For the analysis, we used the reverse transcriptase and protease sequences from baseline resistance, and the Trugene® HIV Genotyping kit (Siemens, Barcelona, Spain). Subtyping was done with REGA v3.0. The maximum likelihood trees constructed with RAxML were used to study HIV-1 clustering. Phylogeographic and phylodynamic profiles were studied by Bayesian inference methods with BEAST v1.7.5 and SPREAD v1.0.6. RESULTS Of the 493 patients infected with HIV-1 subtype B, 234 grouped into 55 clusters, most of which were small (44 clusters ≤ 5 patients, 31 with 2 patients, 13 with 3). The rest (133/234) were grouped into 11 clusters with ≥ 5 patients, and most (82%, 109/133) were men who have sex with men (MSM) grouped into 8 clusters. The association with clusters was more frequent in Spanish (p = 0.02) men (p< 0.001), MSM (p<0.001) younger than 35 years (p = 0.001) and with a CD4+ T-cell count above 350 cells/ul (p<0.001). We estimated the date of HIV-1 subtype B regional epidemic diversification around 1970 (95% CI: 1965-1987), with an evolutionary rate of 2.4 (95%CI: 1.7-3.1) x 10-3 substitutions/site/year. Most clusters originated in the 1990s in MSMs. We observed exponential subtype B HIV-1 growth in 1980-1990 and 2005-2008. The most significant migration routes for subtype B went from inland cities to seaside locations. CONCLUSIONS We provide the first data on the phylodynamic and phylogeographic profiles of HIV-1 subtype B in south Spain. Our findings of transmission clustering among MSMs should alert healthcare managers to enhance preventive measures in this risk group in order to prevent future outbreaks.

Abstract
In order to improve infection prognosis and reduce the existing microbial resistance problem (a challenge similar to that of climate change), a higher implication of the Administration, an increased level of social awareness and the development of specific corporate networks, including the pharmaceutical industry, is needed. However, we must first consolidate Antimicrobial Stewardship Programmes with experts who seek to improve antibiotic therapy effectivity in severe infections and to reduce global antibiotic exposure.

Abstract
Patients with human immunodeficiency virus type 1 (HIV-1) who receive antiretroviral therapy (ART) often achieve increased survival and improved quality of life. In this respect, monotherapy with darunavir/ritonavir (mDRV/r) can be a useful treatment strategy. This prospective study analyses the effect of mDRV/r on sperm quality and viral load in a group of 28 patients who had previously been given conventional ART and who had recorded a viral load <20 copies/mL for at least six months. These patients were given mDRV/r at a dose of 800/100 mg for 48 weeks. At baseline (V0), CD4, CD8, FSH, LH and testosterone levels were measured, together with HIV-1 viral load in plasma and semen. In addition, seminal fluid quality was studied before mDRV/r treatment was prescribed. At week 48 (V1), HIV-1 viral load in plasma and semen and the quality of the seminal fluid were again measured. The results obtained indicate that at V0, 10% of the patients with ART had a positive viral load in seminal fluid (>20 copies/ml), and that at V1, after mDRV/r treatment, this figure had fallen to 3%. The quality of seminal fluid was close to normal in 57% of patients at V0 and in 62% at V1. We conclude that, similar to ART, mDRV/r maintains HIV-1 viral load in most patients, and that there is no worsening in seminal fluid quality.

Abstract
With the efficacy of antiretroviral therapy already guaranteed for all practical purposes, the main objective in the management of HIV-positive patients has moved to reduce and prevent potential long-term toxicities. Nucleos(t)ide-sparing regimens could enable the best to address this issue, with a wide range of current options that may allow adaptation to distinct patient populations. Monotherapy with boosted darunavir and lopinavir has been safely prescribed as maintenance therapy to stable patients on stable antiretroviral therapy without nadir CD4 count < 200/mm³, low-level baseline viremia, prolonged viral suppression, and without prior virologic failure. In the presence of all these requirements, dual therapy with lamivudine plus boosted lopinavir or atazanavir has been shown to be equivalent to standard triple therapy. Other nucleoside-sparing dual therapies, especially using raltegravir combined with boosted darunavir or lopinavir and etravirine or rilpivirine in combination with boosted darunavir, have performed well as simplification strategies or rescue interventions in a wide spectrum of patients as long as drug resistance was absent. With current economical constrains, nuke-sparing regimens have attained a degree of maturity that makes it possible to anticipate that they will play an important role in the optimization of antiretroviral therapy in the near future.

Abstract
The management of infectious diseases is always complex, not only because of its high incidence and mortality, but the difficulty of designing effective treatments that minimize the development of bacterial resistance in the clinical setting. One of the most important options is the reduction of exposure to antibiotic treatment, optimizing by desescalation and shortening the duration of therapy.

Abstract
There are few data about the immunovirological efficacy, safety/tolerability, and durability of maraviroc (MVC) addition to aging patients on suppressive antiretroviral therapy (cART) and undetectable viral load (<50 copies/ml). The aging population is underrepresented in most HIV clinical trials. This study included 80 patients aged ≥50 years and 161 aged <50 years and showed that after 48 weeks of treatment, there was no between-group differences in the median increase of CD4(+) T cells or the virological suppression rate. Safety and tolerability were also comparable. In multivariable analysis, the effect of age was not modified and was independent of the response to MVC. An immunological recovery of ≥100 CD4(+) T cells was significantly less common in those with a longer HIV history (≥15 years) (OR 0.43; p=0.016) or having <200/mm(3) CD4(+) T cells at MVC initiation (OR 0.27; p=0.004). Meanwhile, achieving a CD4/CD8 ratio ≥0.5 at week 48 was less likely in those with CD4(+) T cell counts <200 at MVC initiation (OR 0.09; p<0.0001) or with a previous AIDS event (OR 0.43; p=0.028). In summary, the immunovirological efficacy, safety/tolerability, and durability of MVC addition in patients virologically suppressed were independent of the patient's age at treatment onset.

Abstract
BACKGROUND Problems associated with lifelong antiretroviral therapy, such as need for strict adherence, drug-related toxic effects, difficulties with treatment schedules, and cost, mean that simplification strategies should be sought. We aimed to explore the efficacy and safety of dual treatment with atazanavir-ritonavir plus lamivudine as an option to switch to from standard combination antiretroviral therapy in patients with an HIV-1 infection who are virologically suppressed. METHODS In this randomised, open-label, non-inferiority trial, we recruited patients aged 18 years and older with chronic HIV-1 infection and no previous treatment failure or resistance, and with HIV-1 RNA of less than 50 copies per mL for at least 6 months, negative hepatitis B virus surface antigen, and good general health, from 30 hospitals in Spain. Exclusion criteria were switch in antiretroviral therapy during the previous 4 months, previous virological failure, pregnancy or breastfeeding, Gilbert's syndrome, use of contraindicated drugs, grade 4 laboratory abnormalities, and previous intolerance to any of the study drugs. We randomly assigned patients (1:1; stratified by active hepatitis C virus infection and previous treatment; computer-generated random number sequence) to dual treatment with oral atazanavir (300 mg once daily) and ritonavir (100 mg once daily) plus lamivudine (300 mg once daily) or triple treatment with oral atazanavir (300 mg once daily) and ritonavir (100 mg once daily) plus two nucleos(t)ide reverse transcriptase inhibitors at the discretion of the investigators. The primary endpoint was virological response, defined as HIV-1 RNA of less than 50 copies per mL at week 48, in the per-protocol population, with a non-inferiority margin of 12%. We included patients who received at least one dose of the study drug in the safety analysis. This study is registered at ClinicalTrials.gov, number NCT01307488. FINDINGS Between Sept 29, 2011, and May 2, 2013, we randomly assigned 286 patients (143 [50%] to each group). At week 48 in the per-protocol population, 112 (84%) of 133 patients had virological response in the dual-treatment group versus 105 (78%) of 135 in the triple-treatment group (difference 6% [95% CI -5 to 16%), showing non-inferiority at the prespecified level. 14 (5%) patients developed severe adverse events (dual treatment six [4%]; triple treatment eight [6%]), none of which we deemed related to the study drug. Grade 3-4 adverse events were similar between groups (dual treatment 77 [55%] of 140; triple treatment 78 [55%] of 141). Treatment discontinuations were less frequent in the dual-treatment group (three [2%]) than in the triple-treatment group (ten [7%]; p=0·047). INTERPRETATION In our trial, dual treatment was effective, safe, and non-inferior to triple treatment in patients with an HIV-1 infection who are virologically suppressed who switch antiretroviral therapy because of toxic effects, intolerance, or simplification. This combination has the potential to suppress some of the long-term toxic effects associated with nucleos(t)ide reverse transcriptase inhibitors, preserve future treatment options, and reduce the cost of antiretroviral therapy.

Abstract
Maraviroc is approved for treatment-experienced HIV+ adults in twice-daily administration. Limited data are available on safety, efficacy and use in routine clinical practice, outside of restrictive clinical trials. This retrospective multicenter (27 centers) study included 667 subjects starting a regimen with maraviroc. The primary endpoint was plasma HIV-RNA <50copies/mL and CD4(+) cell count change at 48 and 96weeks (FDA snapshot analysis). 94.4% had CCR5 tropism (58.3% Trofile™, 29.2% population genotype, and 12% genotyping proviral DNA). Half of the subjects received the drug in scenarios or dosages outside the initial approval. Maraviroc was prescribed for salvage in 346 (51.9%) individuals, as a switch strategy due to toxicity in 135 (38.7%), for immune discordance in 75 (11.2%), and for simplification in 48 (7.2%). After salvage therapy, 223 (64.5%) subjects had HIV-RNA <50copies/mL at 48weeks, and 178 (51.4%) at 96weeks. Darunavir/r was included in 224 (64.7%) subjects and associated with higher rates of virological and immunologic efficacy (p<0.001). In multivariate analysis MSM (OR 2.25; 95%CI 1.29-3.94) and baseline HIV-RNA <100,000copies/mL (OR 1.96; 1.06-3.70) were associated with virological suppression. An increase in CD4(+) counts was seen at 48 and 96weeks in subjects with immune discordance (p<0.001). Maraviroc was used once-daily in 142 (21.3%) subjects overall, and 68 (57.4%) in switch/simplification. No new safety signals were identified. Besides in salvage regimens, maraviroc was frequently used in switch due to toxicity, simplification, and immune discordance. The efficacy in salvage in clinical practice was higher than in phase III clinical trials, likely due to availability of new active drugs in the regimen. These results increase our understanding of the efficacy, safety, and conditions of prescription of maraviroc beyond the initial registrational trials and the early manufacturer pharmacovigilance programs.

INTRODUCTION Despite the availability of new antibiotics such as daptomycin, methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia continues to be associated with high clinical failure rates. Combination therapy has been proposed as an alternative to improve outcomes but there is a lack of clinical studies. The study aims to demonstrate that combination of daptomycin plus fosfomycin achieves higher clinical success rates in the treatment of MRSA bacteraemia than daptomycin alone. METHODS AND ANALYSIS A multicentre open-label, randomised phase III study. Adult patients hospitalised with MRSA bacteraemia will be randomly assigned (1:1) to group 1: daptomycin 10 mg/kg/24 h intravenous; or group 2: daptomycin 10 mg/kg/24 h intravenous plus fosfomycin 2 gr/6 g intravenous. The main outcome will be treatment response at week 6 after stopping therapy (test-of-cure (TOC) visit). This is a composite variable with two values: Treatment success: resolution of clinical signs and symptoms (clinical success) and negative blood cultures (microbiological success) at the TOC visit. Treatment failure: if any of the following conditions apply: (1) lack of clinical improvement at 72 h or more after starting therapy; (2) persistent bacteraemia (positive blood cultures on day 7); (3) therapy is discontinued early due to adverse effects or for some other reason based on clinical judgement; (4) relapse of MRSA bacteraemia before the TOC visit; (5) death for any reason before the TOC visit. Assuming a 60% cure rate with daptomycin and a 20% difference in cure rates between the two groups, 103 patients will be needed for each group (α:0.05, ß: 0.2). Statistical analysis will be based on intention to treat, as well as per protocol and safety analysis. ETHICS AND DISSEMINATION The protocol was approved by the Spanish Medicines and Healthcare Products Regulatory Agency (AEMPS). The sponsor commits itself to publishing the data in first quartile peer-review journals within 12 months of the completion of the study. TRIAL REGISTRATION NUMBER NCT01898338.

Abstract
INTRODUCTION AND OBJECTIVE Protease and reverse transcriptase HIV-1 sequences provide useful information for patient clinical management, as well as information on resistance to antiretrovirals. The aim of this study is to evaluate transmission events, transmitted drug resistance, and to georeference subtypes among newly diagnosed patients referred to our center. METHODS A study was conducted on 693 patients diagnosed between 2005 and 2012 in Southern Spain. Protease and reverse transcriptase sequences were obtained for resistance to cART analysis with Trugene(®) HIV Genotyping Kit (Siemens, NAD). MEGA 5.2, Neighbor-Joining, ArcGIS and REGA were used for subsequent analysis. RESULTS The results showed 298 patients clustered into 77 different transmission events. Most of the clusters were formed by pairs (n=49), of men having sex with men (n=26), Spanish (n=37), and below 45 years of age (73.5%). Urban areas from Granada, and the coastal areas of Almeria and Granada showed the greatest subtype heterogeneity. Five clusters were formed by more than 10 patients, and 15 clusters had transmitted drug resistance. CONCLUSIONS The study data demonstrate how the phylogenetic characterization of transmission clusters is a powerful tool to monitor the spread of HIV, and may contribute to design correct preventive measures to minimize it.

Abstract
Survey in 349 HIV infected subjects in 19 Spanish Hospitals in 2010-2011, to assess the reasons for antiretroviral treatment change. Simplification was the most frequent reason for change (37%), followed by toxicity (30%) and treatment failure (21%). There were statistically significant differences according to treatment line and transmission category. In conclusion, in many patients treatment is changed in order to obtain the benefits of a regimen easier to follow.

Abstract
BACKGROUND Assisted reproductive technology (ART) with washed semen can achieve pregnancy with minimal risk of horizontal and vertical transmission of chronic viral diseases (CVD) such as human immunodeficiency virus (HIV), hepati- tis C virus (HCV) and hepatitis B virus (HBV) among serodiscordant couples. How- ever, few studies have been made of the use made by these couples of ARTs or of the obstetric results achieved. MATERIALS AND METHODS In this retrospective study, 93 men who were seropositive for HIV, HCV or HBV and who underwent assisted reproduction treatment at our centre (Hospital Universitario Virgen de las Nieves, Granada, Spain) were included. Washed semen was tested to detect viral particles. Non-infected women were tested before and after each treatment, as were the neonates at birth and after three months. RESULTS A total of 62 sperm samples were washed, and none were positive for the detec- tion of viral molecules. Semen samples from 34 HBV positive males were not washed since the female partner had immunity to hepatitis B. In total, 38 clinical pregnancies were achieved (22% per cycle and 40.9% per couple) out of 173 cycles initiated, and 28 births were achieved (16.2% per cycle and 30.1% per couple), producing 34 live births. The rate of multiple pregnancies was 21.4%. Obstetric and neonatal results were similar in the groups of couples studied. At follow-up, no seroconversion was detected in the women or neonates. CONCLUSION Sperm washing and intracytoplasmic sperm injection are shown to be a safe and effective option for reducing the risk of transmission or super infection in serodiscordant or concordant couples who wish to have a child. Pregnancies ob- tained by ART in couples when the male is CVD infected achieve good obstetric and neonatal results.

Abstract
BACKGROUND Staphylococcus aureus bacteremia (SAB) is associated with significant morbidity and mortality. Several aspects of clinical management have been shown to have significant impact on prognosis. The objective of the study was to identify evidence-based quality-of-care indicators (QCIs) for the management of SAB, and to evaluate the impact of a QCI-based bundle on the management and prognosis of SAB. METHODS A systematic review of the literature to identify QCIs in the management of SAB was performed. Then, the impact of a bundle including selected QCIs was evaluated in a quasi-experimental study in 12 tertiary Spanish hospitals. The main and secondary outcome variables were adherence to QCIs and mortality. Specific structured individualized written recommendations on 6 selected evidence-based QCIs for the management of SAB were provided. RESULTS A total of 287 and 221 patients were included in the preintervention and intervention periods, respectively. After controlling for potential confounders, the intervention was independently associated with improved adherence to follow-up blood cultures (odds ratio [OR], 2.83; 95% confidence interval [CI], 1.78-4.49), early source control (OR, 4.56; 95% CI, 2.12-9.79), early intravenous cloxacillin for methicillin-susceptible isolates (OR, 1.79; 95% CI, 1.15-2.78), and appropriate duration of therapy (OR, 2.13; 95% CI, 1.24-3.64). The intervention was independently associated with a decrease in 14-day and 30-day mortality (OR, 0.47; 95% CI, .26-.85 and OR, 0.56; 95% CI, .34-.93, respectively). CONCLUSIONS A bundle orientated to improving adherence to evidence-based QCIs improved the management of patients with SAB and was associated with reduced mortality.
