Background: Outpatient parenteral antibiotic treatment (OPAT) has proven efficacious for treating infective endocarditis (IE). However, the 2001 Infectious Diseases Society of America (IDSA) criteria for OPAT in IE are very restrictive. We aimed to compare the outcomes of OPAT with those of hospital-based antibiotic treatment (HBAT)., Methods: Retrospective analysis of data from a multicenter, prospective cohort study of 2000 consecutive IE patients in 25 Spanish hospitals (2008-2012) was performed., Results: A total of 429 patients (21.5%) received OPAT, and only 21.7% fulfilled IDSA criteria. Males accounted for 70.5%, median age was 68 years (interquartile range [IQR], 56-76), and 57% had native-valve IE. The most frequent causal microorganisms were viridans group streptococci (18.6%), Staphylococcus aureus (15.6%), and coagulase-negative staphylococci (14.5%). Median length of antibiotic treatment was 42 days (IQR, 32-54), and 44% of patients underwent cardiac surgery. One-year mortality was 8% (42% for HBAT; P < .001), 1.4% of patients relapsed, and 10.9% were readmitted during the first 3 months after discharge (no significant differences compared with HBAT). Charlson score (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.04-1.42; P = .01) and cardiac surgery (OR, 0.24; 95% CI, .09-.63; P = .04) were associated with 1-year mortality, whereas aortic valve involvement (OR, 0.47; 95% CI, .22-.98; P = .007) was the only predictor of 1-year readmission. Failing to fulfill IDSA criteria was not a risk factor for mortality or readmission., Conclusions: OPAT provided excellent results despite the use of broader criteria than those recommended by IDSA. OPAT criteria should therefore be expanded., (© The Author(s) 2019. Published by Oxford University Press for the Infectious Diseases Society of America. All rights reserved.

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality., Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk., Results: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32-3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39-1.88),and non-performed surgery (HR:1.64;95% CI:11.16-1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality., Conclusion: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group., (Copyright © 2019.

Aim: To evaluate the effectiveness and safety of ertapenem in patients hospitalized at home., Patients & Methods: Retrospective analysis of data from Spanish Outpatient Parenteral Antimicrobial Therapy (OPAT) registry., Results: Data from 1428 patients (median age 70 years; 5.4% institutionalized) and 1547 infectious processes (24% self-administration) were analyzed. Clinical cure or improvement was achieved in 93.8% of cases. Rate of related readmissions was 4.2%, of clinically important complications -3.9%, and of adverse drug reactions -3.2%. High comorbidity burden, contagion in nursing home and certain types of infection were associated with worse prognosis. Self-administration was effective and safe, except in case of nursing home-acquired infections., Conclusion: Ertapenem OPAT was effective and safe. Caregivers in nursing homes should be better trained in OPAT-related procedures.

Objective: This study aimed to evaluate the efficiency of treatment of infectious endocarditis (IE) via Self-administered Outpatient Parenteral Antimicrobial Therapy (S-OPAT) supported by a shortening hospital admission program in a hospitalization-at-home unit (HAH), including a short review of the literature., Methods: Ambispective cohort study of 57 episodes of IE in 54 patients treated in an HAH unit between 1988 and 2014 who receive S-OPAT after prior intra-hospital clinical stabilization. Characteristics of each episode of IE, safety and efficiency of the care model, were analyzed., Results: Forty-three (76%) patients were males with a median age of 61 years (SD = 16.5). A total of 37 (65%) episodes affected the native valve (42% the aortic valve). In 75%, a micro-organism was isolated, of which 88% were Gram-positive bacteria. No deaths occurred during HAH program, clinical complications appeared in 30% of episodes, only 6 patients were re-admitted to hospital although no patient died. In the 12 months' follow-up 3 cases had a recurrence. The average cost of a day stay in HAH was €174 while in traditional cardiology hospitalization was €1100. The total average cost of treatment of each episode of IE managed entirely in hospital was calculated as €54,723. Application of the S-OPAT model based on HAH meant a cost reduction of 32.72%., Conclusions: In suitably selected patients, treatment of IE based on S-OPAT supported by a shortening hospital admission care program by means of referral to a HAH unit is a safe and efficient care model which entails a significant cost saving for the public healthcare system.

Background: Infective endocarditis (IE) caused by anaerobic bacteria is a rare and poorly characterized disease. Most data reported in the literature are from case reports [1-3]. Therefore, we assessed the situation of anaerobic IE (AIE) in Spain using the database of the Spanish Collaboration on Endocarditis (GAMES)., Methods: We performed a prospective study from 2008 to 2016 in 26 Spanish centers. We included 2491 consecutive cases of definite IE (Duke criteria)., Results: Anaerobic bacteria caused 22 cases (0.9%) of definite IE. Median age was 66 years (IQR, 56-73), and 19 (86.4%) patients were men. Most patients (14 [63.6%]) had prosthetic valve IE and all episodes were left-sided: aortic valves, 12 (54.5%); and mitral valves, 8 (36.4%). The most common pathogens were Propionibacterium acnes (14 [63.6%]), Lactobacillus spp (3 [13.63%]), and Clostridium spp. (2 [9.0%]), and the infection was mainly odontogenic. Fifteen of the 22 patients (68.2%) underwent cardiac surgery. Mortality was 18.2% during admission and 5.5% after 1 year of follow-up. When patients with AIE were compared with the rest of the cohort, we found that although those with AIE had a similar age and Charlson comorbidity index, they were more likely to have community-acquired IE (86.4% vs. 60.9%, p = 0.01), have undergone cardiac surgery (68.2% vs 48.7% p = 0.06), and have had lower mortality rates during admission (18.2% vs. 27.3%)., Conclusion: IE due to anaerobic bacteria is an uncommon disease that affects mainly prosthetic valves and frequently requires surgery. Otherwise, there are no major differences between AIE and IE caused by other microorganisms., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: Daptomycin is an optimal choice for outpatient parenteral antibiotic therapy (OPAT) because of its safety, once-daily administration and its activity against Gram-positive bacteria. Although daptomycin is increasingly being used in OPAT, limited information about its safety in this scenario is available., Methods: We performed a prospective multicentre pilot study to evaluate the safety of daptomycin in outpatients with proved or suspected Gram-positive infections (DAPTODOM). The primary objective was to evaluate the safety and the secondary objective to evaluate the efficacy in OPAT. We also looked at the development of daptomycin resistance in those cases with microbiological failure., Results: We included 54 patients from 12 Spanish hospitals, 67% male with a mean age of 67.1 years. Most patients (87%) had chronic underlying diseases. The main reason for inclusion was skin and soft-tissue infections in 52%, followed by bacteremia or endocarditis in 34%. Staphylococcus aureus accounted for 44% of the isolates (24% were methicillin-resistant), coagulase-negative staphylococci 15% and enterococci 7%. Two patients (4%) had to be readmitted because of complications; only one patient had an adverse effect related to daptomycin (increase in serum creatine kinase levels), which disappeared after discontinuation (2%). At the end of follow-up, 96% of patients had good outcome and only 4% of patients did not have a clinical or microbiological cure. The use of a 2-minute bolus in 18 cases was not associated with adverse effects., Conclusions: Daptomycin was safe and efficacious in outpatients with Gram-positive bacterial infections and can be administered in 2-minute bolus infusion.

Objective: At present there is a controversy regarding the impact of positive bile cultures on morbidity and mortality rates, and on the incidence of readmissions in patients with biliar disease. The aim of this study was to evaluate the role of bacteriobilia in postoperatory infections, mortality or readmissions in these patients., Methods: The information was obtained from all patients with bile cultures admitted to Hospital Universitario Marqués de Valdecilla (Santander, Spain) from January to December 2011. Clinical, epidemiological and microbiological data and laboratory findings were analyzed. The patients were followed for two years., Results: One hundred and fifty-two patients (65% men) were included. Mean age was 67 years (SD= 15 years). The most frequent diagnoses were acute cholecystitis (79%) and cholangitis (8%). Laparoscopic cholecystectomy was performed in 42% of patients, open cholecystectomy in 45% and percutaneous cholecystostomy in 8%. Bacteriobilia was present in 83 patients (55%). The most frecuent microorganisms isolated were Escherichia coli (31%), Enterococcus faecium (13%) and Klebsiella pneumoniae (13%). The initial antimicrobial agent was a carbapenem in 62 patients (44%) and piperacillin-tazobactam in 28 (18%). There were 39 postoperative infections (26%), 21 readmissions (14%) and 17 patients died during admission (11%). The presence of microorganisms in bile cultures was not a statistically significant predictor of neither complications nor readmissions., Conclusions: Intra-operative bile cultures would allow guide early appropriate antibiotic treatment use in case of infection, or empiric antimicrobial therapy, however there was no correlation between bacteriobilia and postoperative infections, length of stay, mortality or readmissions.

The safety and efficacy of treatment of infectious endocarditis (IE) was evaluated within a program of hospital-in-home (HIH) based on self-administered outpatient parenteral antimicrobial therapy (S-OPAT). IE episodes (n=48 in 45 patients; 71% middle-aged males) were recruited into the HIH program between 1998 and 2012. Following treatment stabilization at the hospital they returned home for HIH in which a physician and/or a nurse supervised the S-OPAT. Safety and efficacy were evaluated as mortality, re-occurrence, and unexpected re-admission to hospital. Of the episodes of IE, 83.3% had comorbidities with a mean score of 2.3 on the Charlson index and 1.5 on the Profund index; 60.4% had pre-existing valve disease (58.6% having had surgical intervention); 8.3% of patients had suffered a previous IE episode; 62.5% of all episodes affected a native valve; 45.8% being mitral; 70.8% of infection derived from the community. In 75% of the episodes there was micro-organism growth, of which 83.3% were Gram positive. Overall duration of antibiotic treatment was 4.8 weeks; 60.4% of this time corresponding to HIH. Re-admission occurred in 12.5% of episodes of which 33.3% returned to HIH to complete the S-OPAT. No deaths occurred during HIH. One year after discharge, 2 patients had recurrence and 5 patients died, in 2 of whom previous IE as cause-of-death could not be excluded. In conclusion, the S-OPAT schedule of hospital-in-home is safe and efficacious in selected patients with IE., (Copyright © 2015 European Federation of Internal Medicine. Published by Elsevier B.V.

Spain lacks detailed data on hip fracture trends despite being the country with the greatest increase in the pensioner-to-provider ratio in Europe. We reproduced a study on hip fracture incidence in a region of northern Spain (Cantabria) carried out 14 years ago to determine whether a secular trend to change is taking place. If such a trend could be found, our objective was to determine whether the effect is solely due to ageing or whether additional variables are involved. We assessed the incidence of hip fracture in patients aged > or =50 years through clinical records from Emergency Units and Orthopedic Surgical Units of all hospitals in the region of Cantabria in 1988 and 2002. A total of 318 new cases of hip fracture were recorded in 1988 and 490 in 2002 (54% increase; p<0.001). No significant changes were noticed following an adjustment for age. Women accounted for the increase in crude hip fracture incidence [246 women and 72 men suffered a hip fracture in 1988 compared to 404 women and 86 men in 2002 (64% increase in women and 19% increase in men; p<0.005 and not significant, respectively)]. The female:male ratio was 3.4 in 1988 versus 4.7 in 2002; following age-adjustment, no significant changes were found (1.8 in 1988 and 1.9 in 2002). The increase in crude hip fracture incidence was greater at cervical (versus trochanteric) sites. Patient residence, time of the year, site of fracture, kind of injury, previous contralateral hip fracture, length of stay, and peri-operative mortality did not differ significantly. In conclusion, a crude hip fracture incidence increase of about 50% in the northern Spanish region of Cantabria has taken place over the last 14 years. This effect does not persist after adjustments have been made for age. The crude rate increase occurred mainly at the expense of women, with a more noticeable rise in cervical fractures as opposed to trochanteric lesions.

Background: Sensitivity to Salsola kali is a frequent cause of allergic respiratory disease in various regions of Spain. However, there are very few articles in which this allergen has been studied., Methods and Results: In order to evaluate the tolerance of this extract, a prospective study has been performed. This study was observational, multi-centred and open, involving 88 patients with allergic respiratory disease due to sensitivity to Salsola, aged between 5 and 52 years. The administration of the extract was performed subcutaneously, through one of two treatment schedules: cluster (8 doses in 4 visits) or conventional (13 doses in 12 visits). A total of 42 adverse reactions were registered, in 26 patients (35 local reactions in 21 patients and 7 systemic reactions in 6 patients). Among the 7 systemic reactions, 4 were registered with the cluster protocol and 2 with the conventional protocol (p = 0.329). In no patients were serious adverse reactions registered., Conclusion: The subcutaneous administration of a Salsola extract is safe and well tolerated, both when administered using a conventional schedule and when using a cluster schedule.

Serum sickness consists of a systemic reaction resulting from the formation of soluble circulating immunocomplexes after the introduction of a foreign substance into the body We studied a 38-year-old woman diagnosed with anxiety, depression and right sacroileitis who was treated with phenylbutazone, ranitidine, clomipramine and levomepromazine. After taking this treatment for 1 month, she presented with fever, diarrhea, localized edemas, generalized pruritic papular and erythematous rash and lymphadenopathies. She presented the same symptoms after oral intake of metamizole. The diagnosis was confirmed following a single-blind, placebo-controlled provocation test with phenylbutazone and a biopsy of the affected skin.

Cross-reactivity between pollen extracts of four species of Oleaceae was studied: olive (Olea europaea), ash (Fraxinus excelsior), privet (Ligustrum vulgare), and lilac (Syringa vulgaris). Thus, 51 patients and 13 atopic controls were studied, by means of intracutaneous skin tests, histamine-release tests against the four extracts, and specific IgE to O. europaea. The proteic content of the four extracts was assessed by SDS-PAGE and immunoblotting, and similarity of all the extracts studied was observed after electrophoresis and immunodetection. Six common bands were found to be responsible for the cross-reactivity, with apparent molecular weights of 49.6, 40, 36.7, 19.7, 16.7, and 14 kDa, respectively. The cross-reactivity was also corroborated by immunoblotting inhibition and FEIA inhibition. The patients had a similar response to the four allergenic extracts used, although the response to Olea was greatest. When the patients were compared by their geographic origin (northern or southern Spain, according to the distribution of areas of olive pollen influence), there were no significant differences between the two groups in skin reactivity, but a higher histamine release was observed for the four extracts in the southern group, although it was significant only for Fraxinus and Ligustrum. This work corroborated the practicality of the diagnostic methods used and the cross-reactivity between the four species studied, as demonstrated by the different methods used. Therefore, we suggest that only O. europaea extract be used in diagnosis and immunotherapy in Oleaceae pollen allergy.

The use of corticosteroids, either oral, parenteral or as aerosol, means a great step forward in bronchial asthma treatment. Nevertheless, given the abuse of their administration, we find more and more frequently, cases of corticodependent bronchial asthma, due to a deficient control in the clinical evolution. For this reason, we performed a study with 39 patients diagnosed with corticodependent intrinsic bronchial asthma. Basal cortisol determination was performed in all, and all of them followed posttreatment with ACTH, antibiotics and mucolytics, as well as follow up of respiratory function parameters and clinical evolution. We found a mean increase in cortisol levels of 488% (basal: 2.49 +/- 0.33 micrograms/dl; posttreatment: 14.59 +/- 2.9 micrograms/dl). Regarding the respiratory function tests, FEV1 improved from 59.38 +/- 4.23% to 68.52% +/- 4.28% (15.4% increase); MEF50 went from 28.62 +/- 3.47% to 35.9 +/- 3.81% (25.4% increase) and MEF25-75 improved from 28.89 +/- 3.47% to 37.05 +/- 3.93% (28.2% increase). Clinical symptomatology and medication improved in general, going from an initial punctuation of 8.5 to a posttreatment score of 7.47. In general, 50% of the patients studied improved from the clinical point of view, only 47.2% had a discrete improvement, and only one patient got worse. Side effects with ACTH treatment appeared in 28.2% of the cases, mainly peripheral edemas, especially in the lower extremities. In conclusion, with patients undergoing lengthy corticosteroid therapy, control of their suprarenal function is absolutely necessary. If a glandular insufficiency appears with low levels of plasmatic cortisol, we advise treatment with ACTH in association with antibiotics.

The international study of asthma and allergy in childhood was designed for the epidemiological investigation of asthma, by means of a standardized methodology. It was started in 1989, as a consequence of very different results obtained in previous epidemiological studies, of which none could be considered as definitive. First, a standardized survey was performed, in order to determine the prevalence of asthma in the United Kingdom, New Zealand and Australia, and subsequently several countries joined them, Spain being one of them. The first objective was to discover the prevalence and severity of bronchial asthma in children who lived in different countries, and to compare the results. Also, it was intended to obtain baseline measurements, in order to assess future trends in asthma prevalence and severity, and to facilitate a base for a subsequent phase of etiologic investigation. For this study, following a protocol previously established, a written survey and a video-survey were given to children aged 13 and 14, and a written survey to the parents of the children aged 6 and 7. All the surveys were performed during the school year 1993-1994. A total of 8,087 surveys were conducted in 53 schools from Pamplona and neighbouring towns. Among the group of children aged 13 and 14, 5.3% had a crisis in the study period, whereas 4.4% suffered from an acute attack. This prevalence was not as high in children aged 6 and 7, for whom the percentages were 3.3% and 3.2%, respectively. We found lower prevalences in the two groups in relation to other countries, and we attribute this result, on one hand to the accessibility to doctors in our area, and on the other hand, to early diagnosis of the disease by specialists, periodic control and suitable etiologic treatment.

In the last years, latex has frequently been found to be involved in immediate hypersensitivity reactions. The first case mentioned with recurrent urticaria and laryngoedema was reported by Stern (1) in 1927. Since then, latex has also been implicated in generalized urticaria, rhinoconjunctivitis, asthma and anaphylaxis. Associated sensitization to several fruits is frequently seen in latex-allergic patients with the symptoms described above. This study was performed in seven patients (six females and one male) with hypersensitivity to latex and concomitant fruit sensitization. Six of them were healthcare personnel. The age of the patients ranged from 25-39 years, with a mean of 30 years. Prick tests and intracutaneous tests with latex (10% w/v in PBS), banana, chestnut, avocado, kiwi and melon were carried out. A specific histamine release test (HRT) was performed according to the fluorometric assay. Antigen-specific IgE was also performed. Latex CAP inhibition with banana and SDS-PAGE immunoblotting were carried out in one patient. Although in latex-allergic patients multiple sensitization to fruits may be observed, banana and avocado are those most frequently involved, followed by chestnut and melon. This is likely to be due to the presence of common antigens in these fruits and latex, as demonstrated in our study only for banana and avocado. We consider that further investigation is needed on the possible sensitization to latex in sanitary personnel reporting symptoms after fruit ingestion.
