Abstract
The objective of this study was to describe the screening for imported diseases among an immigrant population. This retrospective observational study was of all adult immigrants attended at the Tropical Medicine Unit of the Vall d'Hebron Teaching Hospital from September of 2007 to March of 2010. The screening strategy was adjusted by symptoms, country of origin, and length of residence in Europe. Overall, 927 patients were included. The median age was 34.5 years, and 42.1% of patients were male. A diagnosis was made in 419 (45.2%) patients. The most frequent diagnoses were Chagas disease, anemia, latent tuberculosis infection, intestinal parasitosis, hepatitis B virus (HBV) infection, and human immunodeficiency virus (HIV) infection. After screening, more diseases were identified in immigrants from sub-Saharan Africa (new diagnoses in 56.6% of patients) than patients from other geographic areas. The geographic origin and length of residence in a developed country determine the prevalence of diseases; hence, screening protocols must be based on this information.

Abstract
Influenza and meteorological factors have been associated with increases in the incidence of invasive pneumococcal disease (IPD). However, scant data regarding the impact of influenza and the environment on the clinical presentation of IPD are available. An observational study of all adults hospitalized with IPD was performed between 1996 and 2012 in our hospital. The incidence of IPD correlated with the incidence rates of influenza and with environmental data. A negative binominal regression was used to assess the relationship between these factors. Clinical presentation of IPD during the influenza and non-influenza periods was compared. During the study, 1,150 episodes of IPD were diagnosed. After adjusting for confounding variables, factors correlating with the rates of IPD were the incidence of influenza infection (IRR 1.229, 95% CI 1.025-1.472) and the average ambient temperature (IRR 0.921, 95% CI 0.88-0.964). Patients with IPD during the influenza period had a worse respiratory status. A greater proportion of patients had respiratory failure (45.6% vs 52%, p = 0.032) and higher requirements for ICU admission (19.3% vs 24.7%, p = 0.018) and mechanical ventilation (11% vs 15.1%, p = 0.038). When we stratified by invasiveness of pneumococcal serotypes and the presence of comorbid conditions, the increase in the severity of clinical presentation was focused on healthy adults with IPD caused by nonhighly invasive serotypes. Beyond the increase in the burden of IPD associated with influenza, a more severe clinical pattern of pneumococcal disease was observed in the influenza period. This effect varied according to pneumococcal serotype, host comorbidities, and age.

Abstract
Spontaneous bacterial peritonitis (SBP) in liver transplantation (LT) recipients who progress to cirrhosis has received little attention. We investigated the adequacy of empirical treatment with third-generation cephalosporins for SBP in this population and the impact of transplantation on the evolution of the infection. We performed a cohort study with 138 SBP episodes: 19 in LT patients and 119 in non-LT patients. The etiology of SBP was identified for 73.7% of the episodes in LT patients and for 38.7% of the episodes in non-LT patients (P = 0.004). The main microorganisms in recipients were Escherichia coli (35.7%) and Streptococcus pneumoniae (21.4%). The etiologies did not differ in non-LT patients. The cephalosporin sensitivity was similar in the 2 groups (85.7% versus 78.4%, P = 0.7). LT recipients developed renal failure (57.9% versus 25.2%, P = 0.004) and encephalopathy (42.1% versus 22%, P = 0.08) more often than non-LT patients, and the mortality rates during episodes (52.6% versus 13.4%, P < 0.001) and at 6 months (70.6% versus 34.7%, P = 0.005) were higher. According to a multivariate analysis, the mortality-associated risk factors at diagnosis were a Model for End-Stage Liver Disease (MELD) score > 18 odds ratio (OR) = 6.1 and being an LT recipient (OR = 4.45). At 6 months, the risk factors for mortality were a MELD score > 18 (OR = 3.08), being an LT recipient (OR = 3.47), a known etiology (OR = 2.08), and the presence of hepatocellular carcinoma (OR = 3.73).

Abstract
INTRODUCTION Infections caused by resistant gram-positive cocci (GPC), especially to glycopeptides, are difficult to treat in solid organ transplant (SOT) recipients as a result of lower effectiveness and high rates of renal impairment. The aim of this study was to evaluate the use of daptomycin in this population. METHODS Over a 2-year period (March 2008-2010) in 9 Spanish centers, we enrolled all consecutive recipients who received daptomycin to treat GPC infection. The study included 43 patients, mainly liver and kidney transplant recipients. RESULTS The most frequent infections were catheter-related bacteremia caused by coagulase-negative staphylococci (23.2%), skin infection caused by Staphylococcus aureus (11.5%), and intra-abdominal abscess caused by Enterococcus faecium (20.9%). The daily daptomycin dose was 6 mg/kg in 32 patients (74.4%). On day 7 of daptomycin treatment, median estimated area under the curve was 1251 μg/mL/h. At the end of follow-up, analytical parameters were similar to the values at the start of therapy. No changes were observed in tacrolimus levels. No patient required discontinuation of daptomycin because of adverse effects. Clinical success at treatment completion was achieved in 37 (86%) patients. Three patients died while on treatment with daptomycin. CONCLUSION In summary, daptomycin was a safe and useful treatment for GPC infection in SOT recipients.

Abstract
BACKGROUND Current therapeutic options for Chagas' disease are limited to benznidazole and nifurtimox, which have been associated with low cure rates in the chronic stage of the disease and which have considerable toxicity. Posaconazole has shown trypanocidal activity in murine models. METHODS We performed a prospective, randomized clinical trial to assess the efficacy and safety of posaconazole as compared with the efficacy and safety of benznidazole in adults with chronic Trypanosoma cruzi infection. We randomly assigned patients to receive posaconazole at a dose of 400 mg twice daily (high-dose posaconazole), posaconazole at a dose of 100 mg twice daily (low-dose posaconazole), or benznidazole at a dose of 150 mg twice daily; all the study drugs were administered for 60 days. We assessed antiparasitic activity by testing for the presence of T. cruzi DNA, using real-time polymerase-chain-reaction (rt-PCR) assays, during the treatment period and 10 months after the end of treatment. Posaconazole absorption was assessed on day 14. RESULTS The intention-to-treat population included 78 patients. During the treatment period, all the patients tested negative for T. cruzi DNA on rt-PCR assay beyond day 14, except for 2 patients in the low-dose posaconazole group who tested positive on day 60. During the follow-up period, in the intention-to-treat analysis, 92% of the patients receiving low-dose posaconazole and 81% receiving high-dose posaconazole, as compared with 38% receiving benznidazole, tested positive for T. cruzi DNA on rt-PCR assay (P<0.01 for the comparison of the benznidazole group with either posaconazole group); in the per-protocol analysis, 90% of the patients receiving low-dose posaconazole and 80% of those receiving high-dose posaconazole, as compared with 6% receiving benznidazole, tested positive on rt-PCR assay (P<0.001 for the comparison of the benznidazole group with either posaconazole group). In the benznidazole group, treatment was discontinued in 5 patients because of severe cutaneous reactions; in the posaconazole groups, 4 patients had aminotransferase levels that were more than 3 times the upper limit of the normal range, but there were no discontinuations of treatment. CONCLUSIONS Posaconazole showed antitrypanosomal activity in patients with chronic Chagas' disease. However, significantly more patients in the posaconazole groups than in the benznidazole group had treatment failure during follow-up.

Abstract
BACKGROUND Cytomegalovirus (CMV)-negative recipients of a graft from a CMV-positive donor (D+/R-) are at high risk of CMV disease. Current preventive strategies include universal prophylaxis (UP) and preemptive therapy (PT). However, the best strategy to prevent CMV disease and achieve better long-term outcomes remains a matter of debate. METHODS We analyzed the incidence of CMV disease and long-term outcomes including graft dysfunction and patient mortality at 5 years after transplantation with both preventive strategies. High-risk (D+/R-) kidney and liver transplant recipients from the RESITRA cohort were included. RESULTS Of 2410 kidney or liver transplant patients, 195 (8.3%) were D+/R-. The final cohort included 58 liver and 102 kidney recipients. UP was given in 92 patients and 68 received PT; 10.9% and 36.8% developed CMV disease, respectively (P < 0.01). The independent risk factors for CMV disease were PT strategy (hazard ratio [HR], 3.30; 95% confidence interval [CI], 1.6-6.9), kidney transplantation (HR, 3.8; 95% CI, 1.4-9.9), and cyclosporine immunosuppression (HR, 2.4; 95% CI, 1.2-4.7). PT strategy was also a risk factor for CMV disease in both liver transplantation (HR, 11.0; 95% CI, 1.2-98.7) and kidney transplantation (HR, 2.7; 95% CI, 1.3-6.0), independently. The development of CMV replication during the first 2 years after transplantation was a risk factor for graft dysfunction at 5 years after transplantation (odds ratio, 3.4; 95% CI, 1.3-9.0). Nevertheless, no significant differences were seen in either graft dysfunction or mortality between the 2 strategies. CONCLUSIONS The study supports the benefit of the UP strategy to prevent CMV disease in D+/R- liver or kidney transplant patients. The development of CMV replication during the first 2 years after transplantation was associated with graft dysfunction at 5 years after transplantation.

Abstract
Data from published studies regarding risk factors for liver biopsy (LB)-related infectious complications in liver transplant recipients are inconsistent. We carried out a retrospective cohort study analyzing consecutive LBs for orthotopic liver transplant patients at a tertiary hospital (2001-2011): there were 667 LB procedures (575 percutaneous procedures and 92 transjugular procedures) in 286 liver transplant recipients. There were 20 complications in 19 patients (overall incidence = 3.0%): 10 were infectious complications (8 cases of bacteremia and 2 cases of peritonitis). The causal microorganisms were mainly Pseudomonas aeruginosa (4 patients) and Enterobacteriaceae (4 patients). All complications occurred with biopsies performed in patients hospitalized for more than 48 hours (381 biopsies for 201 patients); hence, only this group was included in the risk factor analysis. The variables associated with the development of infectious complications after LB were the presence of impaired biliary drainage at the time of biopsy (40% versus 15.1%, P = 0.03) and low albumin levels (2.4 versus 3.1 g/dL, P = 0.01). In conclusion, according to our experience, infectious complications secondary to LB in liver transplant recipients are related to hospitalization at the time of biopsy, particularly in the presence of impaired biliary drainage and low albumin levels.

Abstract
Strongyloides stercoralis infection is being increasingly diagnosed out of endemic areas. The aim of this study is to evaluate the usefulness of S. stercoralis serology for the management of probable strongyloidiasis in patients presenting with eosinophilia. Overall, 147 patients were included, 89 (60.5%) patients had a positive S. stercoralis serology. Strongyloides stercoralis larvae were detected only in 15 (10.2%) patients. Twenty-eight patients had human immunodeficiency virus infection. Eighty patients received ivermectin 200 mcg/Kg/day for 2 days, and follow-up 6 months after treatment could be performed in 32 patients: 26 (81.3%) patients reached the response to treatment criteria (negative serology 6 months after treatment or when by enzyme-linked immunosorbent assay the optical density ratio of post-treatment to pre-treatment decreased to 0.6), and 11 (34.4%) patients fulfilled the cure criteria (negative serology 6 months after treatment). Strongyloides stercoralis serology is a useful diagnostic tool both in the diagnosis of probable strongyloidiasis and follow-up after treatment.

Abstract
Pneumococcal serotypes are one of the main determinants of pneumococcal disease severity; however, data about their implication in respiratory failure are scarce. We conducted an observational study of adults hospitalised with invasive pneumococcal pneumonia to describe the host- and pathogen-related factors associated with respiratory failure. Of 1258 adults with invasive pneumococcal disease, 615 (48.9%) had respiratory failure at presentation. Patients with respiratory failure were older (62.1 years versus 55.4 years, p<0.001) and had a greater proportion of comorbid conditions. They also had a greater proportion of septic shock (41.7% versus 6.1%, p<0.001), required admission to the intensive care unit more often (38.4% versus 4.2%, p<0.001) and had a higher mortality (25.5% versus 3.5%, p<0.001). After adjustment, independent risk factors for respiratory failure were: age >50 years (OR 1.63, 95% CI 1.15-2.3), chronic lung disease (OR 1.54, 95% CI 1.1-2.15), chronic heart disease (OR 1.49, 95% CI 1.01-2.22) and infection caused by serotypes 3 (OR 1.97, 95% CI 1.23-3.16), 19A (OR 2.34, 95% CI 1.14-4.42) and 19F (OR 3.55, 95% CI 1.22-10.28). In conclusion, respiratory failure is a frequent complication of pneumococcal pneumonia and causes high morbidity and mortality. Pneumococcal serotypes 3, 19A and 19F are the main risk factors for this complication.

Abstract
Latent parasitic infections can reactivate because of immunosuppression. We conducted a prospective observational study of all human immunodeficiency virus (HIV)-infected immigrants who visited the Infectious Diseases Department of the Hospital Universitari Vall d'Hebron, Barcelona, Spain, during June 2010-May 2011. Screening of the most prevalent tropical diseases (intestinal parasitosis, Chagas disease, leishmaniasis, malaria, schistosomiasis, and strongyloidiasis) was performed according to geographic origin. A total of 190 patients were included: 141 (74.2%) from Latin America, 41 (21.6%) from sub-Saharan Africa, and 8 (4.2%) from northern Africa. Overall, 36.8% (70 of 190) of the patients had at least one positive result for any parasitic disease: 5 patients with positive Trypanosoma cruzi serology, 11 patients with positive Schistosoma mansoni serology, 35 patients with positive Strongyloides stercoralis serology, 7 patients with positive Leishmania infantum serology, intestinal parasitosis were detected in 37 patients, malaria was diagnosed in one symptomatic patient. We propose a screening and management strategy of latent parasitic infections in immigrant patients infected with HIV.

Abstract
Molecular methods have been proposed as an alternative tool for the diagnosis of visceral leishmaniasis (VL), but no data are available regarding use for monitoring clinical outcome. A prospective cohort study of human immunodeficiency virus-(HIV) and VL-coinfected patients was conducted in a university-affiliated hospital in Barcelona, Spain. Leishmania parasite load was monitored using a real-time polymerase chain reaction (PCR) at baseline and every 3 months. Cutoff values for PCR were determined using receiver operating characteristic (ROC) curves. Overall, 37 episodes were analyzed, and 25 of these episodes were considered as relapsing episodes. A significant decrease of parasite load measured 3 months after treatment could predict the clinical evolution of VL. A parasite load over 0.9 parasites/mL measured 12 months after treatment could predicts relapse with a sensitivity of 100% and a specificity of 90.9%. Monitoring parasite load by an ultrasensitive quantitative Leishmania PCR is useful to predict the risk of relapse after a VL episode in HIV-infected patients.

Abstract
The aim of this study was to describe the immediate and long-term prognosis of a contemporary cohort of patients with left-sided infective endocarditis (LSIE). A prospective observational cohort study was conducted in a referral centre. Between January 2000 and December 2011, all consecutive adult patients with LSIE were followed-up until death, relapse, recurrence, need for late surgery, or last control. During the active phase of IE, 174 of 438 patients underwent surgery (40% overall; 43% native valve (NVIE), 30% prosthetic valve (PVIE)) and 125 died (29% overall; 26% NVIE, 39% PVIE). The median follow-up in survivors was 3.2 years (interquartile range (IQR) 1.0-6.0 years). Relapses occurred in seven patients (2.2%; 95% CI, 1.1-4.5) and recurrences in eight (2.6%; 95% CI, 1.3-5.0), with an incidence density of 0.0067 per patient-year (95% CI, 0.0029-0.0133) and high mortality (75% of recurrences). Only four of 130 survivors (3.1%; 95% CI, 1.2-7.6) who were treated surgically during the active phase of the disease, and 14/183 (7.7%; 95% CI, 4.6-12.4) of those not undergoing surgery needed operation during follow-up (p 0.09). In the 313 survivors, actuarial survival was 86% at 1 year (87% NVIE, 83% PVIE), 79% at 2 years (81% NVIE, 72% PVIE) and 68% at 5 years (71% NVIE, 57% PVIE). At 1 year, 115 of 397 patients (29.0%; 95% CI, 24.7-33.6) remained alive, with no surgery requirement, relapse or recurrence. LSIE is associated with considerable in-hospital and long-term mortality, especially PVIE. However, relapses, recurrences and the need for late surgery are uncommon.

Abstract
Clostridium difficile-associated disease (CDAD) is the most common cause of nosocomial diarrhea. Information about CDAD in solid organ transplant (SOT) recipients is scarce. To determine its epidemiology and risk factors, we conducted a cohort study in which 4472 SOT patients were prospectively included in the RESITRA/REIPI (Spanish Research Network for the Study of Infection in Transplantation) database between July 2003 and July 2006. Forty-two episodes of CDAD were diagnosed in 36 patients. The overall incidence was 0.94%. Median onset of infection was 31.5 days (range 6-741); in half the cases, onset occurred during the first month after transplantation. In 26% of cases, there was no previous antibiotic use. Independent risk factors for CDAD using Cox regression analysis were previous use of first- and second-generation cephalosporins (HR 3.68; 95%CI 1.8-7.52; P < 0.001), ganciclovir prophylactic use (HR 3.09; 95%CI 1.44-6.62; P = 0.004) and corticosteroid use before transplantation (HR 2.95; 95%CI 1.1-7.9; P = 0.031). There were no deaths related to CDAD. In summary, the incidence of CDAD in SOT was low, most cases were diagnosed soon after transplantation and the prognosis was good.

Abstract
HIV-tuberculosis coinfection is currently one of the greatest health threats, affecting millions of people worldwide, with high morbidity and mortality. Treating both infections can be a challenge and requires some expertise due to multidirectional drug interactions, risk of overlapping side effects, high pill burden and risk of immune reconstitution inflammatory syndrome. This article reviews the general management of tuberculosis/HIV coinfection, focusing on the optimal time to start antiretroviral therapy and which treatments can be safely used. The randomized clinical trials designed to answer the question of when to start antiretroviral therapy (SAPIT, CAMELIA, STRIDE and TIME), published in the last two years, are described and discussed in detail. Summarizing these trials' conclusions, antiretroviral therapy should be started within two weeks of starting tuberculosis treatment if the patient has less than 50 CD4/mm3 and wait to the end of the induction phase (8-12 weeks after starting tuberculosis treatment) if higher CD4 cell counts exist. Treatment options for both tuberculosis and HIV, including the newer available drugs and those in clinical trials, are revised and recommendations for dose adjustments are made based on the latest available literature, with special attention to drug-drug interactions and the necessity of dose adjustments with some drug combinations.

Abstract
AIM AND METHOD The aim of this study was to describe the clinical characteristics and outcome of pandemic influenza A H1N1/2009 (pH1N1) infection, in a retrospective cohort of pediatric patients with kidney and/or liver transplant and confirmed pH1N1 infection from June to December 2009, diagnosed in 2 Spanish teaching hospitals. RESULTS Forty-nine patients were included. Pneumonia was diagnosed in 4 patients (8.2%), and 3 of them required respiratory support. There were no related deaths. CONCLUSION Antiviral treatment within 48 h was associated with a lower likelihood of pneumonia (0/38, 0%) than treatment started after 48 h (4/11, 36.3%) (P < 0.01).
