Abstract
BACKGROUND In the setting of hepatitis C virus (HCV) active infection, liver stiffness (LS)-based strategies identify patients with low risk of developing esophageal variceal bleeding (VB) episodes, in whom unnecessary upper esophagogastroduodenoscopy (UGE) screening can be safely avoided. However, after sustained virological response (SVR), data on the accuracy of the criteria predicting this outcome in HCV-infected patients with cirrhosis, with or without human immunodeficiency virus (HIV) coinfection, are very limited. METHODS This was a multicenter prospective cohort study, where HCV-monoinfected patients and HIV/HCV-coinfected individuals were included if they had (1) SVR with direct-acting antiviral-based therapy; (2) LS ≥9.5 kPa previous to treatment; and (3) LS measurement at the SVR time-point ≥14 kPa. Diagnostic accuracy of HEPAVIR, expanded Baveno VI, and HIV cirrhosis criteria, at the time of SVR, was evaluated. Missed VB episodes, negative predictive values (NPVs), and number of spared UGEs were specifically assessed. RESULTS Four hundred thirty-five patients were included, 284 (65%) coinfected with HIV. Seven (1.6%) patients developed a first episode of VB after SVR. In patients without a previous VB episode, HEPAVIR, expanded Baveno VI and HIV cirrhosis criteria achieved NPV for first VB episode after SVR of 99.5% (95% confidence interval [CI], 97.1%-100%), 100% (95% CI 97.8%-100%), and 100% (95% CI 98%-100%) while sparing 45%, 39%, and 44% of UGEs, respectively. When considering HIV coinfection, the performance of the 3 criteria was similar, both in HCV-monoinfected and HIV/HCV-coinfected individuals. CONCLUSIONS After SVR, predictive LS-based strategies accurately identify HCV-infected patients, HIV coinfected or not, with low risk of developing VB during follow-up. In these specific patients, using HIV cirrhosis criteria maximize the number of spared UGEs while missing no VB episode.

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
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
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
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
PURPOSE Our aim was to analyze the efficacy and safety of didanosine-lamivudine-efavirenz in a cohort of HIV patients starting antiretroviral therapy between January and September 2003. METHOD We undertook a prospective, open-label, observational, multicenter study. RESULTS 163 patients were enrolled. Over a 48-week period, plasma HIV RNA levels declined sharply, with a median decrease at the end of the observation time of >4.62 log copies/mL. The proportion of patients achieving a plasma HIV RNA level below 50 copies/mL was 62.9% (intention-to-treat analysis) at the end of the study period. The mean CD4 cell count increased steadily over time by 199 cells/microL. Antiviral efficacy was similar in patients with a baseline HIV RNA level above or below 100,000 copies/mL. Overall, 57 (34.1%) patients interrupted therapy; 9 due to lack of treatment response, 18 due to adverse side-effects, and 30 patients lost to follow-up or who withdrew their consent. Adherence was very high (90%-95%) and quality of life was good or very good in 69%. CONCLUSION The once-daily combination of didanosine-lamivudine-efavirenz resulted in sustained viral suppression and was well-accepted by patients under real-life conditions, even immunosuppressed patients and those with a high viral load. Associated adverse events and virological failures were few.

Abstract
Abnormal Wnt signaling and impaired cell–cell adhesion due to abnormal E-cadherin and β-catenin function have been implicated in many cancers, but have not been fully explored in nasopharyngeal carcinoma. The aim of this study was to analyze β-Catenin cellular location and E-cadherin expression levels in nasopharyngeal carcinoma. E-cadherin expression levels were also correlated with clinical data and underlying pathology. β-Catenin and E-cadherin expression were examined in 18 nasopharyngeal carcinoma and 7 non-tumoral inflammatory pharynx tissues using immunohistochemical methods. Patient clinical data were collected, and histological evaluation was performed by hematoxylin/eosin staining. β-catenin was detected in membrane and cytoplasm in all cases of nasopharyngeal carcinoma, regardless of histological type; in non-tumoral tissues, however, β-catenin was observed only in the membrane. As for E-cadherin expression levels, strong staining was observed in most non-tumoral tissues, but staining was only moderate in nasopharyngeal carcinoma tissues. E-cadherin expression was associated with β-catenin localization, study group, metastatic disease, and patient outcomes. Reduced levels of E-cadherin protein observed in nasopharyngeal carinoma may play an important role in invasion and metastasis. Cytoplasmic β-catenin in nasopharyngeal carcinoma may impair cell–cell adhesion, promoting invasive behavior and a metastatic tumor phenotype.

Abstract
The objective was to evaluate the effectiveness and safety of simplification from tenofovir-lamivudine (TDF-3TC) to Truvada (TVD) in virologically suppressed HIV patients. We carried out an open-label, multicentre, non-controlled study of HIV patients on a stable regimen including TDF-3TC who switched from TDF-3TC to TVD. Viral load responses at 24 and 48 weeks were evaluated. Changes in the calculated glomerular filtration rates (cGFR; Cockcroft-Gault equation) were analysed at baseline and at 24 and 48 weeks. Patients with drug-related nephrotoxicity (cGFR < 60 mL/min at 48 weeks or interruption of TVD because of renal toxicity) were analysed in detail. Two hundred and ninety-five patients with a mean time on TDF-3TC of 19.9 months (range 8.8-29.8) were enrolled. The third drug was a non-nucleoside reverse transcriptase inhibitor, which was administered to 187 patients (76.4% efavirenz) and a protease inhibitor was administered to 108 (43.5% lopinavir/ritonavir). At 48 weeks, 85.7% of the patients were still taking the same regimen, all with an undetectable viral load. The cGFR (mL/min) decreased from baseline (111 [89-130]) to 48 weeks (105 [84-121]); p < 0.0001. The percentage of patients with a cGFR <60 mL/min at 48 weeks was 3.5. Six patients ceased TVD because of drug-related nephrotoxicity. The only factors associated with nephrotoxicity were age, baseline weight and cGFR. Simplification from TDF-3TC to TVD was associated with a decrease in cGFR, with a low prevalence of nephrotoxicity at 48 weeks.

Abstract
OBJECTIVES To assess the effect of early syphilis on HIV viral load (VL) and CD4 cell count in patients with HIV and to analyze factors associated with changes in HIV VL and CD4 cell count. DESIGN Multicenter study of a series of patients with HIV who were diagnosed with early syphilis infection during 2004 through 2005. Patients who started or changed their highly active antiretroviral therapy (HAART) regimen during the analysis period were excluded. RESULTS One hundred eighteen patients were analyzed: 95.8% were men, mean patient age was 38.2 years, 83.9% were homosexual men, 50.8% were on antiretroviral therapy at the time syphilis was diagnosed, and HIV and syphilis diagnoses were coincident in 38 (32.2%) cases. CD4 cell counts were lower during syphilis than before (590 vs. 496 cells/microL; P = 0.0001) and after syphilis treatment (509 vs. 597 cells/microL; P = 0.0001). The HIV VL increased in 27.6% of patients during syphilis. The only factor associated with an HIV VL increase was not being on HAART, and the only factor associated with a CD4 count decrease >100 cells/microL during syphilis was the prior CD4 cell count. CONCLUSIONS Syphilis infection was associated with a decrease in the CD4 cell count and an increase in the HIV VL in almost one third of the patients. In this series, more than two thirds of the syphilis cases were diagnosed in patients who were previously known to be infected with HIV.

Abstract
Human immunodeficiency virus (HIV) codes for a protein, Rev, that mediates the viral RNA export from the nucleus to the cytoplasm. Recently, it has been found that Sam68, the substrate of Src associated in mitosis, is a functional homologue of Rev, and a synergistic activator of Rev activity. Thus, it has been suggested that Sam68 may play an important role in the post-transcriptional regulation of HIV. Sam68 contains an RNA binding motif named KH [homology to the nuclear ribonucleoprotein (hnRNP) K]. Tyrosine phosphorylation of Sam68 and binding to SH3 domains have been found to negatively regulate its RNA binding capacity. Besides, tyrosine phosphorylation of Sam68 allows the formation of signalling complexes with other proteins containing SH2 and SH3 domains, suggesting a role in signal transduction of different systems in human lymphocytes, such as the T cell receptor, and leptin receptor, or the insulin receptor in other cell types. In the present work, we have found that Sam68 is tyrosine phosphorylated in peripheral blood mononuclear cells (PBMC) from HIV infected subjects, leading to the formation of signalling complexes with p85 the regulatory subunit of PI3K, GAP and STAT-3, and decreasing its RNA binding capacity. In contrast, PBMC from HIV infected subjects have lower expression levels of Sam68 compared with controls. These results suggest that Sam68 may play some role in the immune function of lymphocytes in HIV infection.

Abstract
BACKGROUND The aim of the present study was to analyze the diagnostic profitability of echography as an indicator of extrapulmonary tuberculosis in patients with HIV infection. PATIENTS AND METHODS HIV positive patients presenting fever of long duration were prospectively studied with an active search for specific echographic lesions. Descriptive statistics were performed by variance analysis. The diagnostic profitability of echography was evaluated by the calculation of sensitivity, specificity, positive predictive values (PPV) and negative predictive value (NPV). RESULTS Criteria of prolonged fever was fulfilled by 116 patients. Thirty-five (30.2%) presented specific echographic alterations: 12 had multiple hyoechoic splenic lesions (34.3%), 11 abdominal adenopathies (31.4%), 9 splenic lesions and adenopathies (25.7%) and 3 showed hepato-splenic involvement and adenopathies (8.6%). The final diagnoses of these patients were: one case of toxoplasmosis, 2 MAI infection, 7 with no definitive diagnosis, and 25 (71.4%) tuberculosis. The mean CD4 lymphocyte count was 46.6 x 10(6)/L in patients with tuberculosis with no echographic findings, with a statistically significant difference of p < 0.05. The appearance of some echographic alterations had a global sensitivity of 37.3%, a specificity of 79.6% a PPV of 0.65 and a NPV of 0.51. The isolated findings of hypoechoic splenic lesions showed a sensitivity of 19.23%, a specificity of 95.12%, a PPV of 0.83 and a NPV of 0.47. CONCLUSIONS The presence of multiple hypoechoic splenic lesions showed an elevated specificity, being greater than 95%, making this finding, although infrequent, that of greatest diagnostic profitability in the echographic study of tuberculosis. We therefore consider abdominal echography to be of great usefulness in the evaluation of patients with HIV infection and prolonged fever since the presence of these lesions, in the most severely immunosuppressed patients, may strongly suggest the diagnosis of extrapulmonary tuberculosis.

Abstract
PURPOSE To assess the clinico-biological features appearing in 307 patients with non-Hodgkin's lymphomas (NHL). PATIENTS AND METHODS The clinical records of 338 patients diagnosed of NHL between January 1975 and December 1988 were revised in retrospect. All cases with histologic diagnosis of NHL aged over 14 years were included, and classified in accordance with the Working Formulation criteria. The following data were analysed: age, sex, first complaints, time elapsed since onset, histologic type, number of sites involved, bulky disease, anaemia, thrombocytopenia, LDH, stage, type of treatment and initial response, survival, and cause of death. The statistical evaluation was performed by actuarial analysis (Kaplan and Meier) and comparison (log-rank test) of survival. RESULTS According to the three categories of the malignancies, the NHL were distributed into low-grade (37.8%), intermediate (36.1%) and high-grade (26.9%). The mean age of the series was 56.6 years and the M/F ratio was 1.3. Lymph node enlargement was the commonest finding; 36.4% of the patients had symptoms related with the disease, and 26.7% had bulky disease. Anaemia was present in 37.7% of the cases and thrombocytopenia in 14.3%, with similar distribution among the three grades. High LDH levels were found in 44% of the patients. At diagnosis, 85% of the patients were in advanced stages (III+IV) already. Complete response was attained in 51.1% of the cases, with median survival of 48 months. CONCLUSIONS The clinico-evolutive data found here are similar to other reports in the literature. In one-half of the patients the cause of the first visit is lymph node enlargement. Complete remission is achieved by one out of two patients, this figure being similar for each of the histologic groups. The Working Formulation is useful in determining the different prognostic groups with respect to survival.
