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

OBJECTIVES: To compare causes of death (CoDs) from two independent sources: National Basic Death File (NBDF) and deaths reported to the Spanish HIV Research cohort [Cohort de adultos con infección por VIH de la Red de Investigación en SIDA CoRIS)] and compare the two coding algorithms: International Classification of Diseases, 10th revision (ICD-10) and revised version of Coding Causes of Death in HIV (revised CoDe). METHODS: Between 2004 and 2008, CoDs were obtained from the cohort records (free text, multiple causes) and also from NBDF (ICD-10). CoDs from CoRIS were coded according to ICD-10 and revised CoDe by a panel. Deaths were compared by 13 disease groups: HIV/AIDS, liver diseases, malignancies, infections, cardiovascular, blood disorders, pulmonary, central nervous system, drug use, external, suicide, other causes and ill defined. RESULTS: There were 160 deaths. Concordance for the 13 groups was observed in 111 (69%) cases for the two sources and in 115 (72%) cases for the two coding algorithms. According to revised CoDe, the commonest CoDs were HIV/AIDS (53%), non-AIDS malignancies (11%) and liver related (9%), these percentages were similar, 57, 10 and 8%, respectively, for NBDF (coded as ICD-10). When using ICD-10 to code deaths in CoRIS, wherein HIV infection was known in everyone, the proportion of non-AIDS malignancies was 13%, liver-related accounted for 3%, while HIV/AIDS reached 70% due to liver-related, infections and ill-defined causes being coded as HIV/AIDS. CONCLUSION: There is substantial variation in CoDs in HIV-infected persons according to sources and algorithms. ICD-10 in patients known to be HIV-positive overestimates HIV/AIDS-related deaths at the expense of underestimating liver-related diseases, infections and ill defined causes. CoDe seems as the best option for cohort studies. © 2012 Wolters Kluwer Health | Lippincott Williams &Wilkins.

Extensively pretreated subjects with virological failure (VF) may receive salvage regimens containing NRTIs with only residual or no activity. Once virological suppression is achieved, their contribution remains elusive.This was a multicentre, randomized, prospective study. Subjects with at least one prior VF, HIV-1 RNA <50 copies/mL for 6 months and receiving a regimen with at least two active drugs (one of them a boosted PI) were randomized 1:1 to stop (experimental arm) or maintain (control arm) NRTIs. EudraCT: 2012-000198-21.Ninety subjects were randomized (experimental, n=45; and control, n=45). The mean age was 50 years, 80% were male, the mean CD4+ cell count was 542 cells/mm(3) and the median number of prior VFs was 3. Seventy-four subjects (82%) harboured the mutation M184V/I and the median number of thymidine-associated mutations was 3 (IQR: 0-4). In the experimental arm, thirty-two (71%) subjects removed one NRTI and 13 (29%) subjects removed two. Twenty-two of 45 (49%) discontinued tenofovir disoproxil fumarate. Forty-one of 45 (91.1%, experimental arm) and 44 of 45 (97.8%, control arm) had HIV-1 RNA <50 copies/mL at 48 weeks (difference: -6.7%; 95% CI: -17.4, 4.1). In a post-hoc analysis allowing NRTI reintroduction, efficacy rates were 95.6% and 97.8%, respectively (difference: -2.2%; 95% CI: -7.2, 2.7). Rates of discontinuation at 48 weeks were 2% in both arms. One subject developed a late VF with resistance selection.In patients receiving a successful multidrug salvage regimen with at least two active drugs (one a boosted PI), the withdrawal of inactive NRTIs was safe, rates of VF were low and drug resistance was uncommon at 48 weeks in this small study. This strategy could potentially prevent long-term toxicities, reduce the number of drugs and reduce costs if non-inferiority was met in a fully powered trial.

To evaluate non-adherence to prescribed subcutaneous biologicals in rheumatoid arthritis (RA) patients in Spain.ARCO (Study on Adherence of Rheumatoid Arthritis patients to SubCutaneous and Oral Drugs) was a multicentre, non-interventional retrospective study involving 42 rheumatology clinics from representative hospitals throughout Spain. The primary objective was to assess the percentage of patients (aged 18 years with an established RA diagnosis) with non-adherence to prescribed subcutaneous biologicals using clinical records and hospital pharmacy dispensing logs as the primary information sources. Adherence was assessed using the Medication Possession Ratio (MPR). Additionally, patients completed the Morisky-Green Medication Adherence Questionnaire.A total of 364 patients (77.5% females, mean age 54.9 years, median RA duration since diagnosis 7.8 years) were enrolled in ARCO. Non-adherence (MPR 80%) was reported in 52/363 evaluable patients (14.3%), and was lower in patients receiving initial monthly drug administration (6.4%) than with weekly (17.4%; p=0.034) or every two weeks (14.4%; p=0.102) administration. By multivariate analysis, non-adherence was positively associated with RA duration above the median and with using induction doses. Monthly administration, compared to weekly administration, was inversely associated with non-adherence. Age, gender, order of administration, and changes in the interval of administration, showed no association with non-adherence. Compared with the MPR, the Morisky-Green questionnaire performed poorly in detecting non-adherence.Non-adherence to the prescribed subcutaneous biological drug occurred in 14.3% of patients with RA. Patients using the most convenient administration period (i.e. monthly) had better adherence than those using more frequent dosing schedules.

Local allergic rhinitis is a newly described type of rhinitis involving nasal production of specific immunoglobulin (sIg) E antibodies in the absence of atopy. It can affect patients previously diagnosed with non-allergic rhinitis. Evidence for this entity is supported by clinical symptoms, local production of sIgE, a type 2 helper T cell inflammatory pattern in nasal secretions during natural exposure to aeroallergens, and a positive response to nasal allergen provocation with local nasal production of sIgE to aeroallergens, tryptase, and eosinophil cationic protein (ECP). Based on these new findings, an advanced diagnostic approach is proposed in patients with symptoms suggestive of allergic rhinitis but negative results in skin prick test and serum sIgE determination. Detection of local sIgE in nasal secretions during natural exposure to aeorallergens and a positive nasal allergen provocation test with local production of tryptase, ECP, and sIgE are useful for detecting patients with local allergic rhinitis. © 2010 Esmon Publicidad.

Knowledge of human papillomavirus (HPV) type distribution in populations at risk for anal cancer is needed. Here, we describe the anal HPV genotype distribution in a large Spanish cohort (Cohort of the Spanish HIV Research Network HPV [CoRISHPV]) of HIV-positive men who have sex with men (MSM) according to geographical origin, age, and cytological status. A crosssectional analysis of baseline data from 1,439 HIV-infected MSM (2007 to 2012) was performed. Anal HPV genotyping was performed using the Linear Array HPV genotyping test. Descriptive analyses of subject characteristics, prevalences, and 95% confidence intervals (CI) were performed. The global prevalences of HPV, high-risk HPV (HR-HPV), and low-risk HPV (LRHPV) types were 95.8%, 83.0%, and 72.7%, respectively. Among the HR-HPV types, HPV16 was the most common, followed by HPV59, -39, -51, -18, and -52. The prevalence of multiple HR-HPV infections was 58.5%. There were no differences in the crude analyses between Spanish and Latin-American MSM for most HPV types, and a peak in prevalence for most HPV types was seen in patients in their late thirties. Globally and by specific HPV groups, men with abnormal anal cytologies had a higher prevalence of infection than those with normal cytologies. This study has the largest number of HIV-positive MSM with HPV genotype data analyzed according to cytological status as far as we know. The information gained from this study can help with the design of anal cancer prevention strategies in HIV-positive patients. Copyright © 2013, American Society for Microbiology.

Background. Thymidylate synthase and hypoxia inducible factor-1α play a central role in the control of tumor progression. In the present study, we investigated the effect of three DNA polymorphisms within the thymidylate synthase gene and two within hypoxia inducible factor-1α on the prognosis of pancreatic cancer. Patients and methods. A retrospective study was performed in 59 patients diagnosed with invasive ductal adenocarcinoma of the pancreas and 159 healthy volunteers. The studied DNA polymorphisms were a variable tandem repeat of 28 bp (rs45445694), a G/C single nucleotide polymorphism (rs34743033), and a deletion of 6 bp (ins1494del 6bp; rs34489327) within the thymidylate synthase gene and C1772T and G1790A single nucleotide polymorphisms within hypoxia inducible factor-1α (rs11549465 and rs11549467, respectively). Variable tandem repeats were determined by specific polymerase chain reaction, whereas thymidylate synthase single nucleotide polymorphism G/C, ins1494del 6pb, and hypoxia inducible factor-1α polymorphisms were identified by polymerase chain reaction and RFLP. Thymidylate synthase and hypoxia inducible factor-1α genotype distributions in patients and healthy volunteers were determined. The impact of the polymorphisms on clinico-pathological variables, including survival, was also studied. Results. The frequency of carriers of the variant del6bp allele was significantly higher among patients (70.0% vs 51.0% of healthy donors, P = 0.02); 42% of male patients were homozygous 2R/2R vs 13.6% of females (P = 0.03), but differences regarding gender were not observed among healthy volunteers. Concerning hypoxia inducible factor-1α C1772T and G1790A single nucleotide polymorphisms, the rates of variant T/T and A/A homozygous genotypes were significantly elevated among patients (18.6% vs 5.3%, P = 0.001, and 5.1% vs none, P = 0.021 respectively). Conclusions. In our study, the variant del14946bp allele within the thymidylate synthase gene, and TT and AA genotypes of C1772T and G1790A hypoxia inducible factor-1α single nucleotide polymorphisms were associated with the development of pancreatic cancer. The 2R/2R genotype of variable tandem repeat thymidylate synthase polymorphism might be a risk factor for pancreatic cancer in males. © Il Pensiero Scientifico Editore.

Background: Patients with venous thromboembolism (VTE) treated with anticoagulants are at risk of death from pulmonary embolism (PE) and/or bleeding. However, whether patients who develop VTE in hospital have a higher complication rate than those who develop VTE in an outpatient setting is unclear. Patients and methods: RIETE is an ongoing, prospective registry of consecutive patients with acute, objectively confirmed, symptomatic VTE. We compared the 3-month incidence of fatal PE and fatal bleeding in patients in whom the VTE had developed while in hospital for another medical condition (inpatients) with those who presented to the emergency ward because of VTE (outpatients). Results: Up to April 2008, 22,133 patients with acute VTE were enrolled: 10,461 (47%) presented with PE, 11,672 with deep vein thrombosis. Overall, 6445 (29%) were inpatients. During the study period, those who developed VTE as inpatients had a significantly higher incidence of fatal PE (2.1% vs. 1.5%; odds ratio: 1.4; 95% CI: 1.1-1.7), overall death (7.0% vs. 5.4%; odds ratio: 1.3; 95% CI: 1.2-1.5), and major bleeding (2.9% vs. 2.1%; odds ratio: 1.4; 95% CI: 1.1-1.6) than outpatients. The incidence of fatal bleeding was not significantly increased (0.7% vs. 0.5%; odds ratio: 1.2; 95% CI: 0.9-1.8). In multivariable analysis, inpatient status was significantly associated with a higher risk for fatal PE (odds ratio: 1.3; 95% CI: 1.1-1.7). Conclusions: VTE occurring in hospitalized patients carries a significantly higher risk for death of PE than in outpatients, underscoring the importance of VTE prevention strategies in the hospital setting. © 2010 European Federation of Internal Medicine.

Background: Fournier gangrene is a necrotizing fasciitis, arising in the genital and perineal area. This entity is still associated with a high mortality rate despite improvements in antibiotic and surgical treatment. Methods: This is a retrospective study of all the patients diagnosed and surgically treated for Fournier gangrene at General University Hospital Ramon y Cajal between 1988 and 2008. Possible prognostic factors that could have any influence on the evolution of Fournier gangrene were analyzed. Results: Seventy patients were analyzed, 62 males (88.6%) and 8 females (11.4%) with a mean age of 57.9 ± 13.5 years. Most frequent clinical manifestations were perineal pain (82.9%) and fever (60%). Physical examination revealed edema (91.4%), erythema (88.6%) and perineal skin necrosis (60%). All the patients underwent surgical debridement of necrotic tissue. In 54.3% reoperations were necessary for new surgical debridements. Medical complications rate was 27.1% and mortality one 22.9%. Ethylism, coexistence of neoplasms, presence of skin necrosis, myonecrosis, abdominal wall affection, number of debrided areas, reoperations, concentration of creatinine in serum>1.4 mg/dL, and hemoglobin <10 g/dL, and platelet count <150 × 10 9/L in whole blood are associated with higher mortality rates. Conclusion: Identification of prognostic factors may help to determine high-risk patients in order to establish an optimal treatment, according to severity of the infection and general status. © 2012, Asian Surgical Association.
