Abstract
BACKGROUND Once HIV/HCV-coinfection microelimination has been virtually achieved in some countries, there is no information about the burden of liver disease among people living with HIV (PLWH). The aim of this study was to define the current prevalence and causes of significant liver damage (SLD) in PLWH. METHODS Cross-sectional study including 619 PLWH. SLD was defined as liver stiffness (LS) ≥ 7.2 kPa measured by transient elastography. Nonviral liver damage (NVLD) was considered if there was no evidence injury due to chronic hepatitis C virus (HCV) infection, active hepatitis B (HBV) or E virus infections. RESULTS One hundred and twelve of 619 (18.2%) PLWH showed SLD, including 34/112 (5.5%) with LS ≥14 kPa. 72/112 (64.3%) had cured HCV infection, 4/112 (3.6%) active HBV infection, and 2/112 HBV/prior HCV coinfection. Thus, 40 (35.7%) showed NVLD. Metabolic associated steatohepatitis (MASH) was present in 29/40 (72.5%) of patients with NVLD, alcoholic liver damage in 2/40 (2.5%) and mixed steatohepatitis in 5/40 (12.5%). CONCLUSIONS After HIV/HCV microelimination the burden of liver damage is high among PLWH. Persistent injury after HCV is a very frequent cause of SLD. However, NVLD, mainly due to MASH, is also a common condition in this population.

Abstract
Abstract
Background
The aim of this post-hoc sub analysis of the EXAMINATION-EXTEND study was to analyze 10-year outcomes according to the age of the patient at the time of the first STEMI.
Methods
Out of 1498 STEMI patients included in the EXAMINATION-EXTEND study, those with a previous history of atherosclerotic cardiovascular disease (coronary ischemic event, ischemic stroke, or previous coronary revascularization) were excluded for this analysis. The remaining 1375 patients were divided into three age groups: <55, 55–65 and >65 years. The primary endpoint was 10-year patient oriented composite endpoint (POCE) of all-cause death, any myocardial infarction (MI), or any revascularization. Secondary endpoints included the individual components of the primary endpoint, cardiac death, target vessel myocardial infarction (TVMI), target lesion revascularization (TLR), and stent thrombosis. The association between age and endpoints was adjusted for baseline confounders.
Results
At 10-year follow-up, patients <55 years (Adjusted hazard ratio [HR]: 0.42, 95% CI: 0.33–0.53, p=0.001), and 55–65 years (Adjusted HR: 0.44, 95% IC: 0.35–0.56, p=0.001) showed lower risk of POCE compared with those >65 years, led by a lower incidence of all-cause death (<55: 5.8% vs. 55–65: 11.3% vs. >65 years: 40.67%, p=0.001). Cardiac death was more prevalent in the older group (<55: 3.5% vs. 55–65: 5.5% vs. >65 years: 21.3%, p=0.001). There were not significant differences in the incidence of TVMI, TLR and stent thrombosis among the different age groups. In the landmark analyses, between 5 and 10-year follow-up, young patients exhibited higher incidence of any revascularization (<55: 7.4% vs. 55–65: 4.9% vs. >65 years: 1.7%, p=0.001) and a trend towards a higher incidence of any MI (<55: 5.2% vs. 55–65: 3.6% vs. >65 years: 1.5%, p=0.064). No differences were found in any other endpoints.
Conclusions
In patients with a first STEMI, advanced age was associated with high rates of POCE at 10-year follow-up, in particular, due to all-cause and cardiac death. Conversely, patients who presented at younger age exhibited a high risk of revascularization at long-term follow-up.

Abstract
BackgroundInfections have been indicated to be the cause and / or consequence of the calving and decompensation of some Connective Tissue Diseases and, in principle, both the immunological disorder and the immunosuppressive action of medications contribute to this.ObjectivesTo describe the frequency of infections associated with the various rheumatological pathologies in patients admitted to hospitalization and to know their associated factors.MethodsA descriptive study was carried out in which 3328 medical records belonging to the patients of the Rheumatology service were reviewed during a follow-up period from January 2010 to December 2020, measures of central tendency such as mean, mode, median and applied the Chi square test to appreciate statistical value between the various variables to be correlated.ResultsMost of the patients were female. The main rheumatological pathology was Rheumatoid Arthritis, followed by Systemic Lupus Erythematosus, Osteoarthritis in 3 place and finally in the last box other entities other than those indicated. The main infectious were those of the urinary tract, in the second instance those of skin and soft tissues, in third place the respiratory ones and lastly those not included in the previous categories. The 2 main therapies related to infections were the use of steroids followed by biological therapy (p 0.001).Table 1.Medications received, categories of infections and reason for hospitalization presented by patients in frequencies and percentages.ConclusionIn the present study it was found that infections were the main cause of decompensation and hospitalization in these patients. Infection is the cause of significant morbidity and mortality in rheumatology patients. Conclusions: Based on the observations obtained in the present study, it is recommended that the risks for the development of infections in rheumatology patients be evaluated through stratification systems and thus generate strategies that reduce their frequency.References[1]D Aletaha T, Neogi AJ, Silman J, Funovits DT, Felson CO.

Abstract
BACKGROUND Liver stiffness (LS) at sustained viral response (SVR) is strongly associated with a lower incidence of subsequent hepatic events. HIV NNRTIs may have a beneficial impact on fibrogenesis. OBJECTIVES Our aim was to analyse the influence of NNRTI-based therapy on the change in LS from starting direct-acting antiviral (DAA) therapy to achieving SVR in HIV/HCV-coinfected patients. METHODS Three hundred and thirteen HIV/HCV-coinfected patients who fulfilled the following criteria were included: (i) had achieved SVR with an IFN-free, DAA-including regimen; (ii) LS ≥9.5 kPa before therapy; (iii) LS measurement available at SVR; (iv) seronegative for HBsAg; and (v) ART containing 2 NRTIs plus either 1 NNRTI or 1 integrase inhibitor (INI) or 1-2 NRTIs plus 1 PI. LS changes were assessed. RESULTS Seventy-four patients received NNRTI-based combinations [53 (71.6%) rilpivirine and 16 (21.6%) efavirenz] and 239 patients received other regimens. At baseline, the median (IQR) LS was 16.7 kPa (11.8-25.6) in the NNRTI group and 17.3 kPa (11.9-27.4) in the non-NNRTI group (P = 0.278). The median (IQR) percentage of LS decrease from baseline to SVR was 35.2% (18.2%-52.3%) for NNRTI-based therapy and 29.5% (10%-45.9%) for PI- or INI-based therapy (P = 0.018). In multivariate analysis, adjusted for sex, age, HCV genotype, NRTI backbone and propensity score for HIV therapy, NNRTI-based regimen use was associated with a higher LS decrease [β = 11.088 (95% CI = 1.67-20.51); P = 0.021]. CONCLUSIONS Treatment with NNRTI plus 2 NRTI combinations is associated with a higher LS decline than other ART combinations in HIV/HCV-coinfected patients receiving DAA-based therapy.

Abstract
OBJECTIVES Spain is close to HCV microelimination, so rates of recently acquired HCV infection (RAHC) should decrease. Nowadays, men who have sex with men (MSM) carry the highest risk of HCV acquisition. Our aim was to estimate the incidence of and the factors associated with RAHC, together with reinfection rates, among patients sexually infected by HIV. METHODS Primary RAHC infection was diagnosed when anti-HCV antibody seroconversion was documented. In anti-HCV positive patients, initially without HCV viraemia, a diagnosis of reinfection was established if plasma HCV RNA was detected. RESULTS All 350 patients tested negative for anti-HCV at baseline and had at least one follow-up visit. Among them, there were 16 RAHC cases from 2016 to 2019. RAHC incidence rates [IR (95% confidence interval, CI)] per 100 person-years were 3.77 (0.5-12.9) in 2016, 1.85 (0.6-4.3) in 2017, 1.49 (0.4-3.8) in 2018 and 1.98 (0.6-4.5) in 2019. Only previous sexually transmitted infections [incidence rate ratio (IRR) = 18.23, 95% CI: 1.93-172.1; P = 0.011], male sex (IRR = 8.33, 95% CI: 1.38-54.15; P = 0.026) and sharing chem-sex drugs (IRR: 4.93, 95% CI: 1.17-20.76; P = 0.030), were independently associated with RAHC. Four out of 42 (9.5%) patients became reinfected. CONCLUSIONS The incidence of RAHC among HIV-infected patients showed a decrease after 2016, although a lower but steady incidence of residual cases still remains. HCV reinfections showed a similar pattern. New infections were associated with sharing chem-sex drugs among MSM.

Abstract
BACKGROUND The aim of this study was to assess the impact of HIV infection on the risk of developing hepatocellular carcinoma (HCC) in HCV-infected patients who achieve sustained virological response (SVR) with direct-acting antiviral (DAA). METHODS Multisite prospective cohort study, where HCV-monoinfected patients and HIV/HCV-coinfected individuals were included if they met: 1) SVR with DAA-based combination; 2) Liver stiffness (LS) ≥9.5 kPa previous to treatment; 3) LS measurement at the SVR time-point. The main endpoint was the occurrence of HCC. Propensity score (PS) was calculated to address potential confounders due to unbalanced distribution of baseline characteristics of HIV/HCV-coinfected and HCV-monoinfected patients. RESULTS 1035 HCV-infected patients were included, 667 (64%) coinfected with HIV. After a median (Q1-Q3) follow-up time of 43 (31-49) months, 19 (1.8%) patients developed HCC [11 (3.0%) HCV-monoinfected, 8(1.2%) HIV/HCV-coinfected individuals; p=0.013]. In the multivariable analysis, HIV co-infection was associated with a lower adjusted risk of developing HCC [sHR=0.27, 95% IC (0.08-0.90); p=0.034]. Predictors of HCC emergence were: HCV genotype 3 [sHR=7.9 (2.5-24.9); p<0.001], MELD score at SVR>10 [sHR=1.37 (1.01-1.86); p=0.043] and LS value at SVR [sHR=1.03 (1.01-1.06) for 1 kPa increase; p=0.011]. Using inverse probability weighting method on the PS, HIV-infected patients had a lower risk of HCC [powered HR=0.33 (0.11-0.85)]. CONCLUSIONS Among HCV-infected patients with advanced fibrosis, who achieve SVR with DAA, HIV-coinfection seems to be associated with a lower risk of HCC occurrence. The underlying causes for this finding need to be investigated.

Abstract
CONTEXT Sulphur is one of the most abundant elements in the Universe. Surprisingly, sulphuretted molecules are not as abundant as expected in the interstellar medium and the identity of the main sulphur reservoir is still an open question. AIMS Our goal is to investigate the H2S chemistry in dark clouds, as this stable molecule is a potential sulphur reservoir. METHODS Using millimeter observations of CS, SO, H2S, and their isotopologues, we determine the physical conditions and H2S abundances along the cores TMC 1-C, TMC 1-CP, and Barnard 1b. The gas-grain model Nautilus is used to model the sulphur chemistry and explore the impact of photo-desorption and chemical desorption on the H2S abundance. RESULTS Our modeling shows that chemical desorption is the main source of gas-phase H2S in dark cores. The measured H2S abundance can only be fitted if we assume that the chemical desorption rate decreases by more than a factor of 10 when n H > 2 × 104. This change in the desorption rate is consistent with the formation of thick H2O and CO ice mantles on grain surfaces. The observed SO and H2S abundances are in good agreement with our predictions adopting an undepleted value of the sulphur abundance. However, the CS abundance is overestimated by a factor of 5 - 10. Along the three cores, atomic S is predicted to be the main sulphur reservoir. CONCLUSIONS The gaseous H2S abundance is well reproduced, assuming undepleted sulphur abundance and chemical desorption as the main source of H2S. The behavior of the observed H2S abundance suggests a changing desorption efficiency, which would probe the snowline in these cold cores. Our model, however, highly overestimates the observed gas-phase CS abundance. Given the uncertainty in the sulphur chemistry, we can only conclude that our data are consistent with a cosmic elemental S abundance with an uncertainty of a factor of 10.

Abstract
Hepatic steatosis (HS) is frequently observed in HIV-infected patients. It is not known whether HIV infection is an independent risk factor for HS development. We aimed to analyze whether HIV coinfection was associated with a higher frequency of HS in patients with chronic hepatitis C. This was a retrospective cross-sectional study. 574 subjects with chronic hepatitis C virus (HCV) infection were included, 246 (43%) of them coinfected with HIV. All of them underwent transient elastography with controlled attenuation parameter (CAP) measurement. HS was defined as CAP ≥ 248 dB/m. 147 individuals (45%) showed HS in the HCV-monoinfected group and 100 (40.7%) in the HIV/HCV-coinfected group (p = 0.318). HS was associated with body mass index (BMI) [<25 Kg/m2 vs. ≥25 Kg/m2, 67 (23.5%) vs. 171 (62.9%); p = 0.001], with plasma HDL-cholesterol [<50 mg/dL vs. ≥50 mg/dL, 122 (48.6%) vs. 95 (37.5%), p = 0.012], with plasma triglycerides [<150 mg/dL vs. ≥150 mg/dL, 168 (40.2%) vs. 65 (52.4%); p = 0.016] and with plasma total cholesterol [<200 mg/dL vs. ≥200 mg/dL, 181 (41%) vs. 53 (52.5%); p = 0.035]. In the multivariate analysis, HS was associated with BMI [adjusted OR (AOR) = 1.264 (1.194–1.339); p = 0.001], age [AOR = 1.029 (1.001–1.058); p = 0.047] and HCV genotype 3 infection [AOR = 1.901 (1.081–2.594); p = 0.026]. HIV coinfection was not associated with HS [AOR = 1.166 (0.719–1.892); p = 0.534]. In conclusion, HIV coinfection is not related with an increased frequency of HS in HCV-infected patients.

Abstract
Construction Biotechnology is a new scientific and engineering discipline that has been developing exponentially during the last decade. The main directions of this discipline are 1- the selection of adequate microorganisms, 2- development of micro-processed construction bioprocesses as well as 3- the development of new biotechnologies to produce construction biomaterials. Products resulting in construction biotechnologies are low-cost, sustainable, and environmentally friendly microbial biocements for the improvement of the construction terrain. The bioagents used in construction biotechnologies are pure or enrichment cultures of native microorganisms or microorganisms isolated and activated from the soil. Biotechnologically produced construction materials and microbial mediated construction technologies have many advantages compared to conventional construction materials and processes. The current technological landscape offers an objective vision and perspective of how microbes are used in the construction industry as additives for cement and concrete so that these new technologies be used in different provinces of Ecuador. In that sense, the current situation of cement and concrete production in Ecuador is briefly described to have an overview of the applicability of the new methods based on biogenic materials and the environmental advantages of the creation of construction biomaterials over conventional production.

Abstract
Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg is being investigated in two Phase III trials, AMBER (NCT02431247; treatment-naive adults) and EMERALD (NCT02269917; treatment-experienced, virologically suppressed adults). Week 48 AMBER and EMERALD resistance analyses are presented. Postbaseline samples for genotyping/phenotyping were analyzed from protocol-defined virologic failures (PDVFs) with viral load (VL) ≥400 copies/mL at failure/later time points. Post hoc analyses were deep sequencing in AMBER, and HIV-1 proviral DNA from baseline samples (VL <50 copies/mL) in EMERALD. Through week 48 across both studies, no darunavir, primary PI, or tenofovir resistance-associated mutations (RAMs) were observed in HIV-1 viruses of 1,125 participants receiving D/C/F/TAF or 629 receiving boosted darunavir plus emtricitabine/tenofovir-disoproxil-fumarate. In AMBER, the nucleos(t)ide analog reverse transcriptase inhibitor (N(t)RTI) RAM M184I/V was identified in HIV-1 of one participant during D/C/F/TAF treatment. M184V was detected pretreatment as a minority variant (9%). In EMERALD, in participants with prior VF and genoarchive data (N = 140; 98 D/C/F/TAF and 42 control), 4% had viruses with darunavir RAMs, 38% with emtricitabine RAMs, mainly at position 184 (41% not fully susceptible to emtricitabine), 4% with tenofovir RAMs, and 21% ≥ 3 thymidine analog-associated mutations (24% not fully susceptible to tenofovir) detected at screening. All achieved VL <50 copies/mL at week 48 or prior discontinuation. D/C/F/TAF has a high genetic barrier to resistance; no darunavir, primary PI, or tenofovir RAMs were observed through 48 weeks in AMBER and EMERALD. Only one postbaseline M184I/V RAM was observed in HIV-1 of an AMBER participant. In EMERALD, baseline archived RAMs to darunavir, emtricitabine, and tenofovir in participants with prior VF did not preclude virologic response.

Abstract
Abstract
Background
Some people living with hepatitis C virus (HCV) with sustained virological response (SVR) develop hepatic complications. Liver stiffness (LS) predicts clinical outcome in people living with human immunodeficiency virus (HIV) with active HCV coinfection, but information after SVR is lacking. We aimed to analyze the predictive ability of LS at SVR for liver complications in people living with HIV/HCV with advanced fibrosis treated with direct-acting antivirals (DAA).
Methods
In sum, 640 people living with HIV/HCV fulfilling the following criteria were included: (i) Achieved SVR with DAA-including regimen; (ii) LS ≥ 9.5 kPa before therapy; and (iii) LS measurement available at SVR. The primary endpoint was the occurrence of a liver complication—hepatic decompensation or hepatocellular carcinoma (HCC)—or requiring liver transplant after SVR.
Results
During a median (Q1–Q3) follow-up of 31.6 (22.7–36.6) months, 19 (3%) patients reached the primary endpoint. In the multivariate analysis, variables (subhazard ratio [SHR] [95% confidence interval]) associated with developing clinical outcomes were: prior hepatic decompensations (3.42 [1.28–9.12]), pretreatment CPT class B or C (62.5 [3.08–1246.42]) and MELD scores (1.37 [1.03–1.82]), CPT class B or C at SVR (10.71 [1.32–87.01]), CD4 cell counts <200/µL at SVR time-point (4.42 [1.49–13.15]), FIB-4 index at SVR (1.39 [1.13–1.70]), and LS at SVR (1.05 [1.02–1.08] for 1 kPa increase). None of the 374 patients with LS <14kPa at SVR time-point developed a liver complication or required hepatic transplant.
Conclusions
LS at the time of SVR after DAA therapy predicts the clinical outcome of people living with HIV/HCV with advanced fibrosis. These results suggest that LS measurement may be helpful to select candidates to be withdrawn from surveillance programs.

Abstract
OBJECTIVES The aim of this study was to evaluate adherence to the recommendations of the Spanish guidelines for the initial assessment of patients with HIV infection in the multicentre Cohort of the Spanish HIV/AIDS Network (CoRIS) during the years 2004-2017. METHODS We calculated the percentage of patients who had each of 11 clinical and analytical recommended examinations performed in their initial evaluation. We evaluated the factors associated with not performing each examination with multivariable logistic regression models. RESULTS We included 13 612 patients in the study. In the initial assessment, CD4 count and viral load were determined in more than 98.0% of the patients. Serologies for hepatitis A, B and C and syphilis were determined in 55.8%, 66.4%, 89.8% and 81.7% of the patients, respectively. Total cholesterol and creatinine were determined in 78.7% and 78.9% of the patients, respectively. The lowest proportions of examinations were observed for blood pressure, smoking status and latent tuberculosis screening, which were performed in 43.2%, 50.6% and 53.9% of the patients, respectively. Injecting drug users and heterosexual patients (compared to men who have sex with men) and patients with a lower educational level had a higher risk of having an incomplete initial assessment for a substantial number of examinations. Latent tuberculosis screening was less likely in patients with CD4 counts < 200 cells/µL. CONCLUSIONS The initial assessment of HIV-infected patients is suboptimal for the evaluation of cardiovascular risk, smoking status, screening of syphilis and viral hepatitis, and diagnosis of latent tuberculosis: adherence to the guidelines was low for these examinations.

Abstract
GEMS is an IRAM 30m Large Program whose aim is determining the elemental depletions and the ionization fraction in a set of prototypical star-forming regions. This paper presents the first results from the prototypical dark cloud TMC 1. Extensive millimeter observations have been carried out with the IRAM 30m telescope (3 mm and 2 mm) and the 40m Yebes telescope (1.3 cm and 7 mm) to determine the fractional abundances of CO, HCO+, HCN, CS, SO, HCS+, and N2H+ in three cuts which intersect the dense filament at the well-known positions TMC 1-CP, TMC 1-NH3, and TMC 1-C, covering a visual extinction range from A V ~ 3 to ~20 mag. Two phases with differentiated chemistry can be distinguished: i) the translucent envelope with molecular hydrogen densities of 1-5×103 cm-3; and ii) the dense phase, located at A V > 10 mag, with molecular hydrogen densities >104 cm-3. Observations and modeling show that the gas phase abundances of C and O progressively decrease along the C+/C/CO transition zone (A V ~ 3 mag) where C/H ~ 8×10-5 and C/O~0.8-1, until the beginning of the dense phase at A V ~ 10 mag. This is consistent with the grain temperatures being below the CO evaporation temperature in this region. In the case of sulfur, a strong depletion should occur before the translucent phase where we estimate a S/H ~ (0.4 - 2.2) ×10-6, an abundance ~7-40 times lower than the solar value. A second strong depletion must be present during the formation of the thick icy mantles to achieve the values of S/H measured in the dense cold cores (S/H ~8×10-8). Based on our chemical modeling, we constrain the value of ζ H2 to ~ (0.5 - 1.8) ×10-16 s-1 in the translucent cloud.

Abstract
Paclitaxel is a successful anti-cancer drug that kills cancer cells in two-dimensional culture through perturbation of mitosis, but whether it causes tumour regression by anti-mitotic actions is controversial. Drug candidates that specifically target mitosis, including inhibitors of kinesin-5, AurkA, AurkB and Plk1, disappointed in the clinic. Current explanations for this discrepancy include pharmacokinetic differences and hypothetical interphase actions of paclitaxel. Here, we discuss post-mitotic micronucleation as a special activity of taxanes that might explain their higher activity in solid tumours. We review data showing that cells which exit mitosis in paclitaxel are highly micronucleated and suffer post-mitotic DNA damage, and that these effects are much stronger for paclitaxel than kinesin-5 inhibitors. We propose that post-mitotic micronucleation promotes inflammatory signalling via cGAS–STING and other pathways. In tumours, this signalling may recruit cytotoxic leucocytes, damage blood vessels and prime T-cell responses, leading to whole-tumour regression. We discuss experiments that are needed to test the micronucleation hypothesis, and its implications for novel anti-mitotic targets and enhancement of taxane-based therapies.

Abstract
Little data are available on renal toxicity exerted by direct-acting antivirals (DAAs) in real life. The aim of this study was to assess the impact of direct-acting antivirals against hepatitis C virus infection currently used in Spain and Portugal on the estimated glomerular filtration rate (eGFR) in clinical practise. From an international, prospective multicohort study, patients treated with DAAs for at least 12 weeks and with eGFR ≥30 mL/min per 1.73 m2 at baseline were selected. eGFR was determined using the CKD-EPI formula. A total of 1131 patients were included; 658 (58%) were HIV/HCV-coinfected patients. Among the 901 patients treated for 12 weeks, median (interquartile range) eGFR was 100 (87-107) at baseline vs 97 (85-105) mL/min per 1.73 m2 at week 12 of follow-up (FU12) post-treatment (P < .001). For HIV-coinfected subjects who received tenofovir plus a ritonavir-boosted HIV protease inhibitor (PI/r), baseline vs FU12 eGFR were 104 (86-109) vs 104 (91-110) mL/min per 1.73 m2 (P = .913). Among subjects receiving ombitasvir/paritaprevir with or without dasabuvir, eGFR did not show any significant change. Of 1100 subjects with eGFR >60 mL/min per 1.73 m2 at baseline, 22 (2%) had eGFR <60 mL/min per 1.73 m2 at FU12, but none presented with eGFR <30 mL/min per 1.73 m2 . In conclusion, eGFR slightly declines during therapy with all-oral DAAs and this effect persists up to 12 weeks after stopping treatment in subjects with normal to moderately impaired renal function, regardless of HIV status. Concomitant use of tenofovir plus PI/r does not seem to have an impact on eGFR.

Abstract
The aim of the study was to evaluate whether bacterial translocation (BT) predicts the clinical outcome in HIV/HCV-coinfected patients with compensated cirrhosis. A cohort of 282 HIV/HCV-coinfected patients with cirrhosis and no previous liver decompensation (LD) was recruited. Serum levels of the DNA sequences encoding the well-conserved 16S rRNA subunit (16S rDNA), the lipopolysaccharide (LPS) and soluble CD14 (sCD14) at diagnosis of cirrhosis were measured. Primary endpoint was the emergence of the first LD and/or death of any cause. Secondary endpoints were LD, liver-related death (LRD) and death of any cause. After a median (Q1-Q3) follow-up of 51 (27-72) months, 67 patients (24%; 95% CI: 19-29) developed their first LD or died during follow-up. Baseline levels of 16S rDNA, LPS and sCD14 were not associated with the probability of developing the primary endpoint of the study. The mean (SD) survival time free of LD and/or death according to levels of 16S rDNA (<83, 83-196, 197-355, >355 [copies/μL]) was 78 (5), 72 (5), 81 (4) and 82 (4) months, respectively (P = .5). The corresponding figures for LPS (<0.1, 0.1-0.6, 0.6-1.5, > 1.5 [IU/mL]) were 76 (5), 71 (5), 77 (5) and 81 (4) months, respectively (P = .4). Baseline levels of BT serum markers were not associated with any of the secondary endpoints analysed in the study. Thus, BT does not seem to be a relevant predictor of clinical outcome in HIV/HCV-coinfected patients with compensated cirrhosis.

Abstract
OBJECTIVES There are scant data on the progression of hepatic steatosis (HS) in HIV infection. We therefore evaluated changes in HS over time in HIV-infected patients using the controlled attenuation parameter (CAP). METHODS A prospective cohort of 326 HIV-infected patients was included in this study. All patients underwent a CAP measurement. Changes in steatosis were evaluated by calculating the median (Q1-Q3) difference between baseline and 12-month CAP values. RESULTS The median (Q1-Q3) CAP was 221 (196-252) dB/m at baseline and 224 (198-257) dB/m at the 12-month visit (P = 0.617). Significant steatosis, that is, CAP ≥ 238 dB/m, was observed in 76 individuals (37%) at baseline and in 80 (39%) at the 12-month visit (P = 0.683). The following variables were associated with ΔCAP: plasma HIV RNA [< 50 vs. ≥ 50 HIV-1 RNA copies/mL: median (Q1-Q3) ΔCAP, 4 (-21, 27) vs. -21 (-49, 4) dB/m, respectively; P = 0.024]; body mass index (BMI) [no increase vs. increase: -13 (-40, 4) vs. 14 (-6, 32) dB/m, respectively; P < 0.001]; triglycerides [no increase vs. increase: -1 (-30, 22) vs. 15 (-3, 40) dB/m, respectively; P = 0.001]; fasting plasma glucose [not impaired vs. impaired: -4 (-31, 16) vs. 30 (15, 49) dB/m, respectively; P < 0.001]; and raltegravir [no vs. yes: 5 (-20, 29) vs. -11 (-37.5, 15) dB/m, respectively; P = 0.018]. The only factor independently associated with ΔCAP was BMI [B (standard error): 9.03 (1.9); P < 0.001]. CONCLUSIONS Increases in CAP values over a period of 12 months in HIV-infected patients were strongly associated with elevations in BMI. Other metabolic factors and antiretroviral drugs were not predictors of CAP changes independent of BMI.

Abstract
Our objective was to determine the incidence and clinical manifestations of acute hepatitis E virus (HEV) in HIV-infected patients. A prospective longitudinal study including HIV-infected HEV-seronegative patients was conducted; HEV seroconversion (to IgG and/or IgM) was the main outcome variable. All patients were tested for HEV antibodies every 3-6 months. For patients who developed HEV seroconversion, a data collection protocol was followed to identify associated clinical manifestations and analytical alterations. A total of 627 patients (89.9%) were followed during a median of 11.96 months (IQR: 8.52-14.52 months) and formed the study population. Forty-one patients developed detectable anti-HEV antibodies (7.2 cases per 100 patients/year). Our study found a high incidence of HEV in HIV-infected patients in southern Spain strongly associated with a rural habitat.

Abstract
OBJECTIVE The aim of this study was to determine the predictive capacity of response at treatment week (TW) 4 for the achievement of sustained virological response 12 weeks after the scheduled end of therapy date (SVR12) to treatment against hepatitis C virus (HCV) genotype 3 (GT3) infection with all-oral direct-acting antiviral (DAA) -based regimens. PATIENTS AND METHODS From a prospective multicohort study, HCV GT3-infected patients who completed a course of currently recommended DAA-based therapy at 33 Spanish hospitals and who had reached the SVR12 evaluation time-point were selected. TW4 HCV-RNA levels were categorized as target-not-detected (TND), below the lower limit of quantification (LLOQTD) and ≥LLOQ. RESULTS A total of 123 patients were included, 86 (70%) received sofosbuvir/ daclatasvir±ribavirin, 27 (22%) received sofosbuvir/ ledipasvir/ ribavirin and 10 (8.1%) received sofosbuvir/ ribavirin, respectively. In all, 114 (92.7%) of the 123 patients presented SVR12 in an on-treatment approach, but nine (7.3%) patients relapsed, all of them had presented cirrhosis at baseline. In those who achieved TND, LLOQTD and ≥LLOQ, SVR12 was observed in 81/83 (98%; 95% CI 91.5%-99.7%), 24/28 (85.7%; 95% CI 67.3%-96%) and 9/12 (75%; 95% CI 42.8%-94.5%), respectively; p(linear association) 0.001. Corresponding numbers for subjects with cirrhosis were: 52/54 (96.3%; 95% CI 87.3%-95.5%), 14/18 (77.8%; 95% CI 52.4%-93.6%) and 7/10 (70%; 95% CI 34.8%-93.3%); p 0.004. CONCLUSIONS TW4-response indicates the probability of achieving SVR12 to currently used DAA-based therapy in HCV genotype 3-infected individuals with cirrhosis. This finding may be useful to tailor treatment strategy in this setting.

Abstract
OBJECTIVES Fatty liver disease (FLD) is frequently observed in HIV-infected patients. Obesity and type 2 diabetes mellitus (T2DM) are strongly associated with FLD. Because genetic variants within the fat mass and obesity-associated (FTO) gene have been associated with both pathologies, our aim was to evaluate the association of single nucleotide polymorphisms (SNPs) within the FTO, previously related to obesity or T2DM, with FLD in HIV-infected patients. METHODS FLD was defined as a value of the controlled attenuation parameter (CAP) ≥ 238 dB/m, obtained by transient elastography. Four SNPs within FTO intron 1 (rs11642841, rs8050136, rs9939609 and rs9940128) were genotyped in 421 individuals using a custom Golden Gate protocol. The results were replicated in a validation sample consisting of a further 206 HIV-infected patients. Multivariate logistic regression analyses were conducted in the entire population. RESULTS Three SNPs (rs8050136, rs9939609 and rs9940128) were associated with FLD, with rs9940128 showing the strongest association. This polymorphism also showed an association with FLD in the validation sample. In total, rs9940128 was genotyped in 627 HIV-infected patients, including 267 (42.6%) FLD-diagnosed individuals. The frequency of FLD among rs9940128 AA carriers was 55.7% (63 of 113 individuals) and that in patients without this genotype was 39.7% (204 of 514 individuals) [P = 0.009; adjusted odds ratio 1.88; 95% confidence interval (CI) 1.17-3.01]. CONCLUSIONS Variations within FTO may be predictors of FLD in HIV-infected patients independently of metabolic factors.

Abstract
The purpose of this investigation was to evaluate the impact of liver stiffness (LS) on the response to direct-acting antiviral (DAA)-based therapy against hepatitis C virus (HCV) infection in cirrhotic patients. Those patients included in two Spanish prospective cohorts of patients receiving therapy based on at least one DAA, who showed a baseline LS ≥ 12.5 kPa and who had reached the scheduled time point for sustained virological response evaluation 12 weeks after completing therapy (SVR12) were analysed. Pegylated interferon/ribavirin-based therapy plus an HCV NS3/4A protease inhibitor (PR-PI group) was administered to 198 subjects, while 146 received interferon-free regimens (IFN-free group). The numbers of patients with SVR12 according to an LS < 21 kPa versus ≥21 kPa were 59/99 (59.6%) versus 46/99 (46.5%) in the PR-PI group (p = 0.064) and 41/43 (95.3%) versus 90/103 (87.4%) in the IFN-free group (p = 0.232). Corresponding figures for the relapse rates in those who presented end-of-treatment response (ETR) were 3/62 (4.8%) versus 10/56 (17.9%, p = 0.024) and 1/42 (2.4%) versus 8/98 (8.2%, p = 0.278), respectively. In a multivariate analysis adjusted for age, sex and use of interferon, a baseline LS ≥ 21 kPa was identified as an independent predictor of relapse [adjusted odds ratio, AOR (95% confidence interval, CI): 4.228 (1.344-13.306); p = 0.014] in those patients with ETR. LS above 21 kPa is associated with higher rates of relapse to DAA-based therapy in HCV-infected patients with cirrhosis in clinical practice. LS could help us to tailor the duration and composition of DAA-based combinations in cirrhotic subjects, in order to minimise the likelihood of relapse.

Abstract
OBJECTIVES The aim of the study was to analyse the frequency and degree of potential drug-drug interactions (DDIs) between direct-acting antivirals (DAAs) and concomitant medication used by HIV/hepatitis C virus (HCV)-coinfected patients, including antiretroviral therapy (ART) and other drugs. METHODS All patients with HIV infection and viraemic HCV genotype 1, 3 or 4 coinfection attending a tertiary care centre in Spain (November 2014 to November 2015) were included in the study. DDIs were classified as major, i.e. drugs should not be co-administered, or minor, i.e. close monitoring, dosage alteration or change in timing may be required if drugs are co-administered, following the http://www.hep-druginteractions.org database recommendations. RESULTS A total of 244 patients were included in the study, of whom 224 (92%) were previous injecting drug users. Major DDIs were found for: paritaprevir-r/ombitasvir plus dasabuvir (3D), in 60 (44%) of 138 individuals with genotype 1; paritaprevir-r/ombitasvir (2D), in 22 (37%) of 60 individuals with genotype 4; sofosbuvir/ledipasvir (SOF/LDV), in four (2%) of 198 patients with genotype 1 or 4; simeprevir (SMV) plus SOF, in 160 (81%) of 198 patients with genotype 1 or 4; daclatasvir (DCV) plus SOF, in seven (3%) of 244 patients with genotype 1, 3 or 4 (P < 0.001). Minor DDIs were found for: 3D, in 123 (89%) individuals with genotype 1; 2D, in 52 (87%) individuals with genotype 4; SOF/LDV, in 154 (78%) patients with genotype 1 or 4; SMV plus SOF, in 129 (65%) patients with genotype 1 or 4; DCV plus SOF, in 149 (61%) patients with genotype 1, 3 or 4 (P < 0.001). CONCLUSIONS Drug-drug interactions between DAAs and ART or other commonly prescribed medications are frequently found among HIV/HCV-coinfected patients. Potential major and minor DDIs are more frequent with 3D, 2D and SMV plus SOF regimens.

Abstract
Our aim was to evaluate the killer cell immunoglobulin-like receptors (KIRs) as a marker for the development of thrombocytopenia secondary to Peg-interferon (IFN) therapy in a cohort of human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infected patients. Patients were naive to HCV treatment, receiving a first course of Peg-IFN/Ribavirin combination therapy. Total platelet count (cells ml-1) was determined at each visit, determining platelet decline from baseline to weeks 1, 2, 4, 8 and 12 after starting therapy. The end point of the study was development of thrombocytopenia, defined as a platelet count of <1 50 000 cells ml-1. Fifty-eight HIV/HCV co-infected patients were included in the study, of whom 20 (34.4%) developed thrombocytopenia. The absence of KIR2DS2 was associated with higher and faster rate of thrombocytopenia (54.2% vs 22.5%; P=0.012; 6.6 vs 10.3 weeks; P=0.008). The absence of KIR2DS2 was associated with a greater decline in platelet count and development of thrombocytopenia during Peg-IFN treatment in HIV/HCV co-infected patients.

Abstract
Hepatitis C virus (HCV) viral persistence in patients with spontaneous viral clearance is controversial. Several studies have shown HCV-RNA in peripheral blood mononuclear cells (PBMCs) and/or liver tissue among patients who have cleared the virus spontaneously, suggesting that viral persistence is a common situation that could involve the entire population studied. Thus, our aim was to evaluate HCV-RNA persistence in PBMCs and hepatocytes in subjects infected with the human immunodeficiency virus (HIV). A total of 1508 patients were prospectively followed and tested for anti-HCV antibodies and HCV-RNA to identify the patients who achieved spontaneous viral clearance. In all of the patients, the persistence of HCV-RNA in PBMCs was evaluated longitudinally during 2 years of follow-up. Fifty-nine patients fulfilled the inclusion/exclusion criteria and were included in the study. HCV-RNA was not detected in the PBMCs at baseline [59 PBMCs samples tested; 0 %; 95 % confidence interval (CI): 0-3.3 %] or during the follow-up (147 PBMCs samples tested; 0 %; 95 % CI: 0-2.02 %). Our study shows that HCV viral persistence is not a frequent occurrence in HIV-infected patients who have spontaneously resolved an HCV infection. Thus, the lack of serum HCV-RNA should continue to be addressed as the standard of healing.

Abstract
It is commonly accepted that human immunodeficiency (HIV) coinfection negatively impacts on the rates of sustained virological response (SVR) to therapy with pegylated interferon plus ribavirin (PR). However, this hypothesis is derived from comparing different studies. The aim of this study was to determine the impact of HIV coinfection on SVR to PR in one single population. In a multicentric, prospective study conducted between 2000 and 2013, all previously naïve hepatitis C virus (HCV)-infected patients who started PR in five Spanish hospitals were analyzed. SVR was evaluated 24 weeks after the scheduled end of therapy. Of the 1046 patients included in this study, 413 (39%) were coinfected with HIV. Three hundred and forty-one (54%) HCV-monoinfected versus 174 (42%) HIV/HCV-coinfected patients achieved SVR (p < 0.001). The corresponding figures for undetectable HCV RNA at treatment week 4 were 86/181 (47%) versus 59/197 (30%), p < 0.001. SVR was observed in 149 (69%) HCV genotype 2/3-monoinfected subjects versus 91 (68%) HIV/HCV genotype 2/3-coinfected subjects (p = 0.785). In the HCV genotype 1/4-infected population, 188 (46%) monoinfected patients versus 82 (30%) with HIV coinfection (p < 0.001) achieved SVR. In this subgroup, absence of HIV coinfection was independently associated with higher SVR [adjusted odds ratio (95% confidence interval): 2.127 (1.135-3.988); p = 0.019] in a multivariate analysis adjusted for age, sex, baseline HCV RNA load, IL28B genotype, fibrosis stage, and type of pegylated interferon. HIV coinfection impacts on the rates of SVR to PR only in HCV genotype 1/4-infected patients, while it has no effect on SVR in the HCV genotype 2/3-infected subpopulation.

Abstract
The aim of this study was to assess the efficacy of and the risk of major bleeding during pegylated interferon (peg-IFN)/ribavirin (RBV) treatment among human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients according to the pretreatment platelet count. Two hundred and seventy-four HCV/HIV-coinfected, previously naïve individuals with compensated cirrhosis enrolled in one Spanish prospective cohort who received peg-IFN/RBV were included in this study. The frequency of severe bleeding and sustained virological response (SVR) rate were compared between patients with a pretreatment platelet count ≤70,000/mm(3) and >70,000/mm(3), respectively. Sixty-one (22 %) patients had a baseline platelet count ≤70,000/mm(3). The median (Q1-Q3) pretreatment platelet count was 58,000 (49,000-65,000) cells/mm(3) in the platelet ≤70,000 group and 129,000 (102,500-166,000) cells/mm(3) in the platelet >70,000 group (p < 0.0001). Seventeen (28 %) subjects of the platelet ≤70,000 group and 71 (33 %) patients of the platelet >70,000 group achieved SVR (p = 0.4). Only 2 (3.2 %) patients in the platelet ≤70,000 group developed a severe hemorrhagic event, specifically esophageal variceal bleeding. The efficacy of therapy with peg-IFN/RBV in HIV/HCV-coinfected patients with low pretreatment platelet counts is comparable to that found in the overall subset of subjects with compensated cirrhosis. The frequency of severe hemorrhagic events related with this therapy is low in this population.

Abstract
Con la finalidad de evaluar el efecto de la presencia o no de sombra durante el pastoreo sobre el crecimiento y confort térmico de corderas mestizas West African, se realizó un estudio utilizando 24 hembras ovinas de 13,08 ± 3,0 kg de peso vivo, las cuales fueron distribuidas al azar en dos tratamientos: SOMBRA: pastoreo en potrero de pasto estrella (Cynodon nlemfluensis) con acceso voluntario a sombra artificial o techo de lona de 36 m2 (3 m2 por animal) y SOL: pastoreo en potrero de pasto estrella sin disponibilidad de sombra natural o artificial. La experiencia se realizó en el Laboratorio-Sección Ovinos de la Facultad de Agronomía - Universidad Central de Venezuela. Los animales se encontraban pastoreando en dos potreros de pasto estrella durante 6 semanas. Las mediciones realizadas fueron: mediciones climáticas tomadas con dos estaciones meteorológicas portátiles (una para cada potrero y la de sombra colocada debajo del techo) que registraban temperatura ambiente (TA, °C), humedad relativa (HR, %) y radiación solar (RS, w/m2), con estas mediciones se estimó el índice de temperatura y humedad o ITH. Temperatura corporal (°C) y frecuencia respiratoria, para estimar el coeficiente de tolerancia al calor (CTC). El crecimiento de las corderas fue evaluado a través de las mediciones: peso vivo (PV), ganancia diaria de peso (GDP), largo corporal (LC), perímetro torácico (PT), altura a la cruz (AC), con las cuales se estimaron los índices de masa corporal 1 (IMC1) e índice de masa corporal 2 (IMC2). En cuanto a las variables climáticas, la TAmax y HR promedio resultaron mayores para SOMBRA que para SOL, en 1,3 °C y 8,1 %, respectivamente (p

Abstract
While hepatitis C virus (HCV) infection seems to be expanding among HIV-infected men who have sex with men (MSM), the rate of coinfection in intravenous drug users (IDU) is assumed to remain constant. We evaluated the serial prevalence of HIV/HCV coinfection across all risk groups for HIV infection in Spain. We used data from 7045 subjects included in the multicentre, prospective Spanish Cohort of Adult HIV-infected Patients (CoRIS) between 2004 and 2011. We analysed risk factors for HIV/HCV coinfection by logistic regression analyses. The prevalence of HIV/HCV coinfection decreased from 25.3% (95% CI, 23.1-27.5) in 2004-2005 to 8.2% (95% CI, 6.9-9.5) in 2010-2011. This trend was consistently observed from 2004 to 2011 among all risk groups: IDU, 92.4% to 81.4%; MSM, 4.7% to 2.6%; heterosexual men, 13.0-8.9%; and heterosexual women, 14.5-4.0% (all P < 0.05). Strongest risk factors for HIV/HCV coinfection were IDU (OR, 54.9; 95% CI, 39.4-76.4), birth decade 1961-1970 (OR, 2.1; 95% CI, 1.1-3.7) and low educational level (OR, 2.4; 95% CI, 1.6-3.5). Hence, the prevalence of HIV/HCV coinfection decreased in Spain between 2004 and 2011. This decline was observed across all risk groups and is likely to be explained by a declining burden of HCV in the general population.

Abstract
HIV-1 induces activation of complement through the classical and lectin pathways. However, the virus incorporates several membrane-bound or soluble regulators of complement activation (RCA) that inactivate complement. HIV-1 can also use the complement receptors (CRs) for complement-mediated antibody-dependent enhancement of infection (Ć-ADE). We hypothesize that hypofunctional polymorphisms in RCA or CRs may protect from HIV-1 infection. For this purpose, 139 SNPs located in 19 RCA and CRs genes were genotyped in a population of 201 Spanish HIV-1-exposed seronegative individuals (HESN) and 250 HIV-1-infected patients. Two SNPs were associated with infection susceptibility, rs1567190 in CR2 (odds ratio (OR) = 2.27, P = 1 × 10(-4)) and rs2842704 in C4BPA (OR = 2.11, P = 2 × 10(-4)). To replicate this finding, we analyzed a cohort of Italian, sexually HESN individuals. Although not significant (P = 0.25, OR = 1.57), similar genotypic proportions were obtained for the CR2 marker rs1567190. The results of the two association analyses were combined through a random effect meta-analysis, with a significant P-value of 2.6 x 10(-5) (OR = 2.07). Furthermore, we found that the protective CR2 genotype is correlated with lower levels CR2 mRNA as well as differences in the ratio of the long and short CR2 isoforms.

Abstract
BACKGROUND AND PURPOSE Excitatory amino acid transporters (EAATs) in the CNS contribute to the clearance of glutamate released during neurotransmission. The aim of this study was to explore the role of EAATs in the regulation of locus coeruleus (LC) neurons by glutamate. EXPERIMENTAL APPROACH We measured the effect of different EAAT subtype inhibitors/enhancers on glutamate- and KCl-induced activation of LC neurons in rat slices. EAAT2-3 expression in the LC was also characterized by immunohistochemistry. KEY RESULTS The EAAT2-5 inhibitor DL-threo-β-benzyloxaspartic acid (100 μM), but not the EAAT2, 4, 5 inhibitor L-trans-pyrrolidine-2,4-dicarboxylic acid (100 μM) or the EAAT2 inhibitor dihydrokainic acid (DHK; 100 μM), enhanced the glutamate- and KCl-induced activation of the firing rate of LC neurons. These effects were blocked by ionotropic, but not metabotrobic, glutamate receptor antagonists. DHK (100 μM) was the only EAAT inhibitor that increased the spontaneous firing rate of LC cells, an effect that was due to inhibition of EAAT2 and subsequent AMPA receptor activation. Chronic treatment with ceftriaxone (200 mg·kg(-1) i.p., once daily, 7 days), an EAAT2 expression enhancer, increased the actions of glutamate and DHK, suggesting a functional impact of EAAT2 up-regulation on the glutamatergic system. Immuhistochemical data revealed the presence of EAAT2 and EAAT3 surrounding noradrenergic neurons and EAAT2 on glial cells in the LC. CONCLUSIONS AND IMPLICATIONS These results remark the importance of EAAT2 and EAAT3 in the regulation of rat LC by glutamate. Neuronal EAAT3 would be responsible for terminating the action of synaptically released glutamate, whereas glial EAAT2 would regulate tonic glutamate concentrations in this nucleus.

Abstract
Several data suggest that low-density lipoprotein receptor (LDLR) is a co-receptor for hepatitis C virus (HCV). Soluble LDLR can inhibit HCV infectivity; greater plasma low-density lipoprotein levels are associated with treatment success; LDLR genotypes have a synergistic impact on the likelihood of achieving SVR with Peg-IFN plus RBV, as well as on viral kinetics after starting treatment. The objective of this study was to assess the impact of genetic polymorphisms in genes related to cholesterol synthesis and transport pathways on pre-treatment plasma HCV viral load (VL). A total of 442 patients infected with HCV and treatment naive were prospectively recruited. One hundred forty-four SNPs located in 40 genes from the cholesterol synthesis/transport and IL28B were genotyped and analyzed for genetic association with pre-treatment plasma HCV VL. SNPs rs1433099 and rs2569540 of LDLR showed association with plasma HCV VL (P=4 × 10(-4) and P=2 × 10(-3)) in patients infected with genotypes 1 and 4. A haplotype including the last three exons of LDLR showed association with the cutoff level of 600 000 IU ml(-1) VL for genotypes 1 and 4 (OR=0.27; P=8 × 10(-6)), as well as a quantitative VL (mean±s.d.: 6.19±0.9 vs CC+CG 5.58±1.1 logIU ml(-1), P=8 × 10(-5)). LDLR genotypes are a major genetic factor influencing HCV VL in patients infected with genotypes 1 and 4.

Abstract
The aim of this study was to assess the impact of the genetic pattern (GP) defined by the single nucleotide polymorphisms (SNPs) rs14158 of low-density lipoprotein receptor (LDLR) and rs12979860 of interleukin-28B (IL28B) genes on the outcome and features of hepatitis C virus (HCV) infection in patients with and without human immunodeficiency virus (HIV) coinfection. 314 HIV/HCV-coinfected and 109 HCV-monoinfected patients treated with pegylated interferon (Peg-IFN) plus ribavirin (RBV), as well as 51 patients with HCV spontaneous clearance (SC), were included. Variations in both SNPs were determined by the TaqMan polymerase chain reaction (PCR) assay. In the 286 patients chronically infected by HCV genotypes 1 or 4, both rs14158 CC and rs12979860 CC were associated with a higher rate of sustained virological response (SVR), and these effects were complementary in both HCV-monoinfected and HIV/HCV-coinfected patients. Thus, 24 % of patients with rs14158/rs12979860 TT-TC/TT-TC, 33 % with TT-TC/CC, 44.2 % with CC/TT-TC, and 75.8 % harboring CC/CC attained SVR (p < 0.001). SC was associated with the IL28B genotype (66.7 % CC in SC vs. 42.6 % among those with chronic infection, p < 0.001) but not with the LDLR genotype. There was no association between GP and the plasma level of alanine aminotransferase (ALT) or the presence of advanced fibrosis. There is a complementary effect between the IL28B and LDLR genotypes on the probability of achieving SVR after Peg-IFN/RBV therapy in patients with HCV 1 or 4. Thus, the predictive value of IL28B genotype is modulated by the LDLR genotype in both HCV-monoinfected and HIV/HCV-coinfected patients. This complementary effect of both genotypes is also observed on the plasma levels of low-density lipoprotein cholesterol (LDL-C).

Abstract
It has previously been shown that nitric oxide (NO) synthase is involved in the development of opioid tolerance. The aim of the present work was to study the effect of NO on μ-opioid receptor (MOR) desensitization. Furthermore, we explored the possible role of reactive oxygen species (ROS) in this effect. Single-unit extracellular and whole-cell patch-clamp recordings were performed on locus coeruleus (LC) neurons from rat brain slices. Perfusion with high concentrations of Met(5)-enkephalin (ME) caused a concentration-related reduction of opioid effect, reflecting the induction of homologous MOR desensitization. The NO donors sodium nitroprusside and diethylamine NONOate markedly enhanced the ME-induced MOR desensitization, although the acute effect of ME on K(+) conductance was not affected by sodium nitroprusside. Continuous perfusion with the antioxidants melatonin, trolox, 21-[4-(2,6-di-1-pyrrolidinyl-4-pyrrimidinyl)-1-piperazinyl]-pregna-1,4,9(11)-triene-3,20-dione(Z)-2-butenedioate (U74389G), and diethyldithiocarbamate prevented the effect of sodium nitroprusside on MOR desensitization, but they did not themselves alter the desensitization. Like sodium nitroprusside, the ROS-generating molecule H(2)O(2) enhanced MOR desensitization induced by ME. However, α(2)-adrenoceptor desensitization induced by noradrenaline was not modified by H(2)O(2), suggesting a selective action of ROS on MOR. Our results suggest that elevated levels of NO, which may be reached in pathological processes, enhance homologous desensitization of MOR in the LC, probably through a mechanism involving ROS generation.

Abstract
OBJECTIVE Noninvasive tests that can be used in place of liver biopsy to diagnose fibrosis have major limitations. They either leave a significant proportion of patients without a definitive diagnosis or produce inaccurate results. Moreover, the performance of these tests is lower in HIV/hepatitis C virus (HCV) coinfection. Against this background, we examined the utility of serum matrix metalloproteinase 2 (MMP-2) and tissue inhibitor of metalloproteinase 1 (TIMP-1) measurements in combination with routine clinical data to predict fibrosis in HIV/HCV-coinfected patients. METHODS Patients with a liver biopsy who had not received anti-HCV therapy were included in the study. A model including variables independently associated with fibrosis was constructed. Diagnostic accuracy was determined by measuring the area under the receiver operating characteristic curve (AUROC). Positive (PPV) and negative (NPV) predictive values were calculated. RESULTS Ninety patients were included in the study. Aspartate aminotransferase (AST), platelet count and MMP-2 were predictors of significant fibrosis (F≥2) and cirrhosis (F4). A score constructed using these variables yielded an AUROC of 0.76 for F≥2 and 0.88 for F4. Score cut-offs detected (value ≥3.5) and excluded (value ≤1.5) F≥2 with a PPV of 87% and an NPV of 88%. Thirty-one patients (34%) were correctly diagnosed using these cut-offs, with four (13%) incorrect classifications. Cirrhosis was excluded with a certainty of 98% and diagnosed with a probability of 83%. Two (17%) of 12 patients were misclassified as having cirrhosis. The AST to platelet count index and MMP-2 levels were sequentially applied to detect F≥2. Forty-one patients (46%) were identified with this approach, with six (15%) misclassifications. CONCLUSION MMP-2 levels can be used in combination with AST and platelet count to aid the diagnosis of liver fibrosis in HIV/HCV-coinfected patients.

Abstract
BACKGROUND Amiodarone is a drug widely used for the treatment of arrhythmias. In 16% of amiodarone-treated patients it causes changes in the thyroid function. The aim of this study was to determine the importance of amiodarone-induced thyroid dysfunction in the population of Navarre, studied between 2001 and 2007. METHODS We present a retrospective study that considers the characteristics of 182 amiodarone-treated patients with thyroid dysfunction who had been referred to our Institute. We determined a series of biochemical and instrumental investigations (measurement of thyrotrophin, free thyroid hormones and thyroid autoantibodies; thyroid sonography and thyroid scintigraphy uptake). RESULTS Screening of the thyroid function, recommended before starting amiodarone treatment, was carried out in only 20.9 % of the patients. Forty-one percent of patients developed amiodarone induced hypothyroidism; in 76% of them the drug was withdrawn. Hypothyroidism appears after 21 (+/- 12) months of amiodarone treatment. Forty-eight point six developed permanent hypothyroidism. This group of patients had higher serum levels of TSH (thyrotropin) and were treated for less time with amiodarone. Fifty-nine percent of patients developed amiodarone induced thyrotoxicosis; 59.4 % were diagnosed with thyrotoxicosis (AIT) type 1, 30.6% AIT type 2 and the remaining 10 % were diagnosed with mixed thyrotoxicosis. Thyrotoxicosis appears after 29.5 (+/- 17) months of amiodarone treatment. The serum levels of free thyroxine were significantly higher in the AIT type 2 than in the AIT type1. All patients were treated with antithyroid drugs and/or corticoids. Some patients were admitted to hospital due to the severity of their illness. CONCLUSIONS In our study, amiodarone induced thyrotoxicosis was more frequent than hypothyroidism (59% vs 41%) because Navarre is an iodine-deficient area. It is necessary to control the thyroid function after 2-3 years of amiodarone treatment.

Abstract
Transient elastometry (TE) could provide a more accurate evaluation of the frequency and risk factors of liver fibrosis in hepatitis C virus (HCV) infection than that based on biopsy. The aim of this study was to assess the prevalence of and factors associated with significant liver fibrosis in a large population of HIV/HCV-coinfected patients. HIV/HCV-coinfected patients, who had participated in a cross-sectional, multicenter, retrospective study of liver fibrosis using noninvasive markers and in whom a determination of liver stiffness (LS) by TE was available, were included in this analysis. Factors potentially associated with significant fibrosis (LS ≥ 9 kPa) were analyzed. One thousand three hundred and ten patients fulfilled the inclusion criteria, 526 (40%) of them showed LS ≥ 9 kPa and 316 (24%) cirrhosis (LS ≥ 14 kPa). The factors independently associated with significant fibrosis [adjusted odds ratio (95% confidence interval, P value) were the following: older age [1.04 (1.01-1.07), 0.002], daily alcohol intake > 50 g/day [1.58 (1.10-2.27), 0.013] and the length of HCV infection [1.03 (1.00-1.06), 0.023]]. A CD4 cell count lower than < 200 per mm(3) [1.67 (0.99-2.81), 0.053] and HCV genotype 4 [0.66 (0.42-1.02), 0.066] were marginally associated with LS ≥ 9 kPa. In conclusion, the prevalence of cirrhosis in HIV/HCV-coinfected patients seems to be higher than previously reported in studies based on liver biopsy. Older age, alcohol consumption and lower CD4 cell counts are related with significant fibrosis. The latter association supports an earlier starting of antiretroviral therapy in this setting.
