Background and aims Limited data are available on the effectiveness and tolerability of direct-acting antivirals (DAAs) therapies in the real world for HCV-infected patients with comorbidities. This study aimed to describe the effectiveness of OBV/PTV/r +/- DSV (3D/2D regimen) with or without ribavirin (RBV) in HCV or HCV/HIV co-infected patients with GT1/GT4 and CKD (IIIb-V stages), including those under hemodialysis and peritoneal dialysis in routine clinical practice in Spain in 2015. Material and methods Non-interventional, retrospective, multicenter data collection study in 31 Spanish sites. Socio-demographic, clinical variables, study treatment characteristics, effectiveness and tolerability data were collected from medical records. Results Data from 135 patients with a mean age (SD) of 58.3 (11.4) years were analyzed: 92.6% GT1 (81.6% GT1b and 17.6% GT1a) and 7.4% GT4, 14 (10.4%) HIV/HCV co-infected, 19.0% with fibrosis F3 and 28.1% F4 by FibroScan (R), 52.6% were previously treated with pegIFN and RBV. 11.1%, 14.8% and 74.1% of patients had CKD stage IIIb, IV and V respectively. 68.9% of patients were on hemodialysis; 8.9% on peritoneal dialysis and 38.5% had history of renal transplant. A total of 125 (96.2%) of 135 patients were treated with 3D, 10 (7.4%) with 2D and 30.4% received RBV. The overall intention-to-treat (ITT) sustained virologic response at week 12 (SVR12) was 92.6% (125/135) and the overall modified-ITT (mITT) SVR12 was 99.2% (125/126). The SVR12 rates (ITT) per sub-groups were: HCV mono-infected (91.7%), HCV/HIV co-infected (100%), GT1 (92.0%), GT4 (100%), CKD stage IIIb (86.7%), stage IV (95%) and stage V (93%). Among the 10 non-SVR there was only 1 virologic failure (0.7%); 4 patients had missing data due lost to follow up (3.0%) and 5 patients discontinued 3D/2D regimen (3.7%): 4 due to severe adverse events (including 3 deaths) and 1 patient ' s decision. Conclusions These results have shown that 3D/2D regimens are effective and tolerable in patients with advanced CKD including those in dialysis with GT 1 or 4 chronic HCV mono-infection and HIV/HCV coinfection in a real-life cohort. The overall SVR12 rates were 92.6% (ITT) and 99.2% (mITT) without clinically relevant changes in eGFR until 12 weeks post-treatment.

[Aim] We describe the effectiveness and safety of the interferon-free regimen ombitasvir/paritaprevir/ritonavir plus dasabuvir with or without ribavirin (OBV/PTV/r ± DSV ± RBV) in a nationwide representative sample of the hepatitis C virus (HCV) monoinfected and human immunodeficiency virus-1/hepatitis C virus (HIV/HCV) coinfected population in Spain., [Material and methods] Data were collected from patients infected with HCV genotypes 1 or 4, with or without HIV-1 coinfection, treated with OBV/PTV/r ± DSV ± RBV at 61 Spanish sites within the initial implementation year of the first government-driven “National HCV plan.” Effectiveness was assessed by sustained virologic response at post-treatment week 12 (SVR12) and compared between monoinfected and coinfected patients using a non-inferiority margin of 5% and a 90% confidence interval (CI). Sociodemographic and clinical characteristics or patients and adverse events (AEs) were also recorded., [Results] Overall, 2,408 patients were included in the intention-to-treat analysis: 386 (16%) were patients with HIV/HCV. Patient selection reflected the real distribution of patients treated in each participating region in Spain. From the total population, 96.6% (95% CI, 95.8–97.3%) achieved SVR12. Noninferiority of SVR12 in coinfected patients was met, with a difference between monoinfected and coinfected patients of −2.2% (90% CI, −4.5% - 0.2%). Only genotype 4 was associated with non-response to OBV/PTV/r ± DSV ± RBV treatment (p, [Conclusions] Our results confirm that OBV/PTV/r ± DSV ± RBV is effective and generally well tolerated in a representative sample of the HCV monoinfected and HCV/HIV coinfected population in Spain within the experience of a national strategic plan to tackle HCV., The design, study conduct, and financial support for the study were provided by AbbVie (https://www.abbvie.com/).

Objetivo: Rever o tratamento farmacológico mais eficaz, entre corticoides e antivíricos, na melhoria clínica da Paralisia Facial Periférica Idiopática. Fontes de dados: Pubmed, sítios de medicina baseada na evidência, Índex de Revistas Médicas Portuguesas e referências bibliográficas dos artigos selecionados. Métodos de Revisão: Foi realizada uma pesquisa de normas de orientação clínica, revisões sistemáticas, meta-análises (MA) e ensaios clínicos aleatorizados e controlados, publicados entre 01/2005 e 04/2012, em inglês e português, utilizando os termos MeSH: Glucocorticoids; Antiviral Agents; Bell Palsy; Facial Paralysis. Para avaliação dos níveis de evidência (NE) e atribuição de forças de recomendação foi utilizada a escala Strength of Recommendation Taxonomy (SORT) da American Family Physician. Resultados: Foram encontrados 181 artigos, dos quais foram selecionados sete MA. Três MA suportam de forma consistente e significativa o benefício clínico do uso de corticoide versus placebo (NE 1). O uso de antivíricos não foi melhor que o placebo em dois estudos (NE 2). A combinação de corticoide e antivírico foi semelhante ao corticoide isolado em dois estudos e em quatro estudos foi reportado um benefício da combinação relativamente ao uso isolado de corticoide, sem significado estatístico. Este benefício da combinação de corticoide e antivírico foi potencialmente mais relevante em casos de paralisia severa (NE 2). Conclusões: A corticoterapia continua a ser o tratamento com a melhor evidência clínica (Recomendação A). Não existe evidência de benefício dos antivíricos, isoladamente ou em associação com corticoides, no tratamento da Paralisia de Bell (Recomendação B). Em doentes com paralisia severa poderá, potencialmente, existir um pequeno benefício na adição de antivíricos à terapêutica com corticoides (Recomendação B). São de realçar as diversas limitações metodológicas, assim como a heterogeneidade dos estudos. Objective: The objective of this study was to review the evidence for the most effective pharmacological treatment for idiopathic peripheral facial paralysis using corticosteroids and antiviral agents. Data sources: PubMed, evidence based medicine websites, Portuguese Medical Journal Index and references of selected articles were searched. Methodology: An electronic database search was conducted for clinical guidelines, systematic reviews, meta-analysis (MA) and randomized controlled clinical trials, published between 01/2005 and 04/2012, in English and Portuguese, using the MeSH terms: Glucocorticoids; Antiviral Agents; Bell Palsy; Facial Paralysis. The Strength of Recommendation Taxonomy (SORT) of the American Family Physician was used for the assessment of levels of evidence (LE) and the strength of recommendations. Results: Of the 181 articles found, seven MA were included. Three MA found significant clinical benefit from corticosteroid therapy compared to placebo treatment (LE 1). The use of antiviral drugs was no better than placebo in two studies (LE 2). The combination of corticosteroids and antiviral drugs was found to be similar to isolated corticosteroid therapy in two studies. In four studies, increased benefit from combination therapy was found compared to corticosteroid treatment alone, though this difference was not statistically significant. Benefit from the combination treatment was possibly more likely in cases of severe paralysis (LE 2). Conclusions: Evidence is strongest for the benefits of corticosteroids in the treatment of idiopathic facial nerve paralysis (Recommendation A). There is no evidence of benefit for antiviral drugs either alone or in combination with corticosteroids in the treatment of Bell’s palsy (Recommendation B). In patients with severe paralysis, there may be a small benefit in adding an antiviral drug to steroid therapy (Recommendation B). Numerous methodological limitations in the reported studies as well as the heterogeneity between studies were noted.

To assess the long-term healthcare costs and health outcomes in association with the access to new direct-acting antivirals (DAAs), during the first year of the National Strategic Plan for Chronic Hepatitis C (SPCHC) in patients with chronic hepatitis C (CHC) in Spain. A decision tree and a lifetime Markov model were developed to simulate the natural history, morbidity, and mortality of a cohort of 51,900 patients with CHC before (pre-DAA strategy) and after (post-DAA strategy) access to DAAs, following SPCHC approval. The percentage of patients treated, transition probabilities, disease management costs, health state utility values, sustained virologic response rates and treatment costs were obtained from the literature and published data from Spain. The results were expressed in terms of costs (€, 2016), quality-adjusted life years (QALYs) and prevention of clinical events, with an annual discount rate of 3%. The post-DAA strategy would prevent 8,667 cases of decompensated cirrhosis, 5,471 cases of hepatocellular carcinoma, 1,137 liver transplants and 9,608 liver-related deaths. The cohort of 51,900 patients would require investments of 1,606 and 1,230 million euros with the post-DAA and pre-DAA strategies, respectively. This would produce 819,674 and 665,703 QALYs. The use of new DAA-based treatments in CHC patients during the first year after the implementation of the SPCHC significantly reduced long-term morbidity and mortality and increased quality of life; demonstrating that this plan is an efficient use of public health resources. Gilead Sciences for the development of the analysis.

AIM To demonstrate the non-inferiority (15% non-inferiority limit) of monotherapy with tenofovir disoproxil fumarate (TDF) vs the combination of lamivudine (LAM) plus adefovir dipivoxil (ADV) in the maintenance of virologic response in patients with chronic hepatitis B (CHB) and prior failure with LAM. METHODS This study was a Phase IV prospective, randomized, open, controlled study with 2 parallel groups (TDF and LAM+ADV) of adult patients with hepatitis B e antigen (HBeAg)-negative CHB, prior failure with LAM, on treatment with LAM+ADV for at least 6 mo, without prior resistance to ADV and with an undetectable viral load at the start of the study, in 14 Spanish hospitals. The follow-up time for each patient was 48 wk after randomization, with quarterly visits in which the viral load, biochemical and serological parameters, adverse effects, adherence to treatment and consumption of hospital resources were analysed. RESULTS Forty-six patients were evaluated [median age: 55.4 years (30.2-75.2); 84.8% male], including 22 patients with TDF and 24 with LAM+ADV. During study development, hepatitis B virus DNA (HBV-DNA) remained undetectable, all patients remained HBeAg negative, and hepatitis B surface antigen (HBsAg) positive. Alanine aminotransferase (ALT) values at the end of the study were similar in the 2 groups (25.1 +/- 7.65, TDF vs 24.22 +/- 8.38, LAM+ADV, P = 0.646). No significant changes were observed in creatinine or serum phosphorus values in either group. No significant differences between the 2 groups were noted in the identification of adverse effects (AEs) (53.8%, TDF vs 37.5%, LAM+ADV, P = 0.170), and none of the AEs which occurred were serious. Treatment adherence was 95.5% and 83.3% in the TDF and the LAM+ADV groups, respectively (P = 0.488). The costs associated with hospital resource consumption were significantly lower with the TDF treatment than the LAM+ADV treatment ((sic)4943 +/- 1059 vs (sic)5811 +/- 1538, respectively, P < 0.001). CONCLUSION TDF monotherapy proved to be safe and not inferior to the LAM+ADV combination therapy in maintaining virologic response in patients with CHB and previous LAM failure. In addition, the use of TDF generated a significant savings in hospital costs.

Introduction: Boceprevir (BOC) was one of the first oral inhibitors of hepatitis C virus (HCV) NS3 protease to be developed. This study assessed the safety and efficacy of BOC + pegylated interferon-alpha 2a/ribavirin (PEG-IFN/RBV) in the retreatment of HIV-HCV co-infected patients with HCV genotype 1. Methods: This was a phase III prospective trial. HIV-HCV (genotype 1) co-infected patients from 16 hospitals in Spain were included. These patients received 4 weeks of PEG-IFN/RBV (lead-in), followed by response-guided therapy with PEG-IFN/RBV plus BOC (a fixed 44 weeks was indicated in the case of cirrhosis). The primary endpoint was the sustained virological response (SVR) rate at 24 weeks post-treatment. Efficacy and safety were evaluated in all patients who received at least one dose of the study drug. Results: From June 2013 to April 2014, 102 patients were enrolled, 98 of whom received at least one treatment dose. Seventy-three percent were male, 34% were cirrhotic, 23% had IL28b CC, 65% had genotype 1a, and 41% were previous null responders. The overall SVR rate was 67%. Previous null-responders and cirrhotic patients had lower SVR rates (57% and 51%, respectively). Seventy-six patients (78%) completed the therapy scheme; the most common reasons for discontinuation were lack of response at week 12 (12 patients) and adverse events (six patients). Conclusions: Response-guided therapy with BOC in combination with PEG-IFN/RBV led to an overall SVR rate of 67%, but an SVR rate of only 51% in patients with cirrhosis. The therapy was generally well tolerated. Although the current standards of care do not include BOC + PEG-IFN/RBV, the authors believe that this combination can be beneficial in situations where new HCV direct antiviral agent interferonfree therapies are not available yet., Funded by Merck: BOC-HIV Study.Maria Martinez-Rebollar is funded by a grant Sara Borrell, CM13-00123, from Instituto de Salud Carlos III, Ministerio Economia y Competitividad. - Other authors declare no other conflict of interest.

Introduction Patients with influenza A (H1N1)v infection have developed rapidly progressive lower respiratory tract disease resulting in respiratory failure. We describe the clinical and epidemiologic characteristics of the first 32 persons reported to be admitted to the intensive care unit (ICU) due to influenza A (H1N1)v infection in Spain. Methods We used medical chart reviews to collect data on ICU adult patients reported in a standardized form. Influenza A (H1N1)v infection was confirmed in specimens using real-time reverse transcriptase-polymerase-chain-reaction (RT PCR) assay. Results Illness onset of the 32 patients occurred between 23 June and 31 July, 2009. The median age was 36 years (IQR = 31 - 52). Ten (31.2%) were obese, 2 (6.3%) pregnant and 16 (50%) had pre-existing medical complications. Twenty-nine (90.6%) had primary viral pneumonitis, 2 (6.3%) exacerbation of structural respiratory disease and 1 (3.1%) secondary bacterial pneumonia. Twenty-four patients (75.0%) developed multiorgan dysfunction, 7 (21.9%) received renal replacement techniques and 24 (75.0%) required mechanical ventilation. Six patients died within 28 days, with two additional late deaths. Oseltamivir administration delay ranged from 2 to 8 days after illness onset, 31.2% received high-dose (300 mg/day), and treatment duration ranged from 5 to 10 days (mean 8.0 +/- 3.3). Conclusions Over a 5-week period, influenza A (H1N1)v infection led to ICU admission in 32 adult patients, with frequently observed severe hypoxemia and a relatively high case-fatality rate. Clinicians should be aware of pulmonary complications of influenza A (H1N1)v infection, particularly in pregnant and young obese but previously healthy persons., This study has been supported in part by SEMICYUC (Sociedad Espanola de Medicina Intensiva, Criticos y Unidades Coronarias), Generalitat de Catalunya Grant (AGAUR/SGR09/1226), CIBERes Enfermedades Respiratorias (06/06/036) and Institut Recerca Pere Virgili (IISPV).

Background: Postherpetic neuralgia (PHN) is a chronic neuropathic pain that results from alterations of the peripheral nervous system in areas affected by the herpes zoster virus. The symptoms include pain, paresthesia, dysesthesia, hyperalgesia, and allodynia. Despite the availability of pharmacological treatments to control these symptoms, no treatments are available to control the underlying pathophysiology responsible for this disabling condition. Methods/design: Patients with herpes zoster who are at least 50 years old and have a pain score of 4 or higher on a visual analogue scale (VAS) will be recruited. The aim is to recruit 134 patients from the practices of general physicians. Participants will be randomized to receive gabapentin to a maximum of 1800 mg/day for 5 weeks or placebo. Both arms will receive 1000-mg caplets of valacyclovir three times daily for 7 days (initiated within 72 h of the onset of symptoms) and analgesics as needed. The primary outcome measure is the percentage of patients with a VAS pain score of 0 at 12 weeks from rash onset. The secondary outcomes measures are changes in quality of life (measured by the SF-12 questionnaire), sleep disturbance (measured by the Medical Outcomes Study Sleep Scale), and percentage of patients with neuropathic pain (measured by the Douleur Neuropathique in 4 Questions). Discussion: Gabapentin is an anticonvulsant type of analgesic that could prevent the onset of PHN by its antihypersensitivity action in dorsal horn neurons., This study was funded by the Ministry of Health, Carlos III Institute (grant PI12/01813). We also received support from the Health Promotion and Preventive Activities-Primary Health Care Network, sustained by the Ministry of Health, Carlos III Institute, Redes Tematicas de Investigacion Cooperativa en Salud (RETIC) award RD12/0005/0011, co-financed by the European Union European Regional Development Fund.
