RESUMEN
OBJECTIVES: Using data of patients from the inception cohort Registro Español de Lupus Eritematoso Sistémico (RELES), we aimed to analyse the incidence of severe infection in the first two years of follow-up and how predictors of infection change during the course of systemic lupus erythematosus (SLE). MATERIAL AND METHODS: The study included 282 patients. Markers of lupus activity, prednisone doses and immunosuppressive therapy were compared between patients with and without infections in the first and second year of the disease. Drug therapy administered during the first month of follow-up has been considered as a potential predictor of infections during the first year and medications administered during the first year have been considered potential predictors of infections during the second. RESULTS: Nineteen patients (6.4%) had a documented episode of major infection during the first year of follow-up and 16 patients (5.67%) during the second. The following variables were associated with infections during the first year: hypocomplementaemia at diagnosis ( p < 0.01), nephritis at diagnosis ( p = 0.03), SLEDAI score ( p < 0.01), prednisone >30 mg/day ( p = 0.01), methylprednisolone pulses ( p = 0.05) and mycophenolate use ( p = 0.02). The independent variables in the final model were hypocomplementaemia (odds ratio (OR) 4.41, 95% confidence interval (CI) 0.96-20.20, p = 0.05) and a dose of prednisone >30 mg/day (OR 6.60, 95% CI 1.34-32.42, p = 0.02). The following variables were associated with infections during the second year: dose of prednisone > 7.5 mg/day ( p = 0.05), methylprednisolone pulses ( p = 0.07), duration of therapy with antimalarials ( p = 0.09), therapy with mycophenolate ( p = 0.01), therapy with cyclophosphamide ( p = 0.05). The independent variables in the final model were a dose of prednisone >7.5 mg/day (OR 4.52, 95% CI 0.99-21, p = 0.054) and duration of therapy with antimalarials as a protective factor (OR 0.99, 95% CI 0.99-1.00, p = 0.053). CONCLUSIONS: The low incidence of early infections in the RELES cohort is partially explained by the extended use of antimalarials and by the general avoidance of prolonged high doses of prednisone. Patients with high baseline activity are at a higher risk of infection during the first months but therapy with medium-high doses of prednisone is the main predictor of infectious events. Thus, every effort should be made to limit oral glucocorticoid use from the very beginning of the SLE course.

OBJECTIVES: To evaluate the clinical characteristics of patients with interstitial lung disease (ILD) in the setting of a large cohort of systemic sclerosis (SSc) patients, and to analyse the differences according to the SSc subtype (following the modification of classification criteria of the American College of Rheumatology for SSc proposed by LeRoy and Medsger), factors are associated with moderate-to-severe impairment of lung function, as well as mortality and causes of death. METHODS: A descriptive study was performed, using the available data from the Spanish Scleroderma Study Group. RESULTS: Twenty-one referral centers participated in the registry. By April 2014, 1374 patients with SSc had been enrolled, and 595 of whom (43%) had ILD: 316 (53%) with limited cutaneous SSc (lcSSc), 240 (40%) with diffuse cutaneous SSc (dcSSc), and 39 (7%) with SSc sine scleroderma (ssSSc). ILD in the lcSSc and the ssSSc subsets tended to develop later, and showed a less impaired forced vital capacity (FVC) and a ground glass pattern on high-resolution computed tomography (HRCT) less frequently, compared with the dcSSc subset. Factors related to an FVC < 70% of predicted in the multivariate analysis were: dcSSc, positivity to anti-topoisomerase I antibodies, a ground glass pattern on HCRT, an active nailfold capillaroscopy pattern, lower DLco, older age at symptoms onset, and longer time between symptoms onset and ILD diagnosis. Finally, SSc-associated mortality and ILD-related mortality were highest in dcSSc patients, whereas that related to pulmonary arterial hypertension was highest in those with lcSSc-associated ILD. CONCLUSIONS: Our study indicates that ILD constitutes a remarkable complication of SSc with significant morbidity and mortality, which should be borne in mind in all three subgroups (lcSSc, dcSSc, and ssSSc).

The objective of the study is to determine the importance of the mode of onset as prognostic factor in systemic sclerosis (SSc). Data were collected from the Spanish Scleroderma Registry (RESCLE), a nationwide retrospective multicenter database created in 2006. As first symptom, we included Raynaud's phenomenon (RP), cutaneous sclerosis, arthralgia/arthritis, puffy hands, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), and digestive hypomotility. A total of 1625 patients were recruited. One thousand three hundred forty-two patients (83%) presented with RP as first symptom and 283 patients (17%) did not. Survival from first symptom in those patients with RP mode of onset was higher at any time than those with onset as non-Raynaud's phenomenon: 97 vs. 90% at 5 years, 93 vs. 82% at 10 years, 83 vs. 62% at 20 years, and 71 vs. 50% at 30 years (p < 0.001). In multivariate analysis, factors related to mortality were older age at onset, male gender, dcSSc subset, ILD, PAH, scleroderma renal crisis (SRC), heart involvement, and the mode of onset with non-Raynaud's phenomenon, especially in the form of puffy hands or pulmonary involvement. The mode of onset should be considered an independent prognostic factor in systemic sclerosis and, in particular, patients who initially present with non-Raynaud's phenomenon may be considered of poor prognosis.

PURPOSE: As elective axillary dissection is loosing ground for early breast cancer (BC) patients both in terms of prognostic and therapeutic power, there is a growing interest in predicting patients with (nodal) high tumour burden (HTB), especially after a positive sentinel node biopsy (SNB) because they would really benefit from further axillary intervention either by complete lymph-node dissection or axillary radiation therapy. METHODS/PATIENTS: Based on an analysis of 1254 BC patients in whom complete axillary clearance was performed, we devised a logistic regression (LR) model to predict those with HTB, as defined by the presence of three or more involved nodes with macrometastasis. This was accomplished through prior selection of every variable associated with HTB at univariate analysis. RESULTS: Only those variables shown as significant at the multivariate analysis were finally considered, namely tumour size, lymphovascular invasion and histological grade. A probability table was then built to calculate the chances of HTB from a cross-correlation of those three variables. As a suggestion, if we were to follow the rationale previously used in the micrometastasis trials, a threshold of about 10% risk of HTB could be considered under which no further axillary treatment is warranted. CONCLUSIONS: Our LR model with its probability table can be used to define a subgroup of early BC patients suitable for axillary conservative procedures, either sparing completion lymph-node dissection or even SNB altogether.

OBJECTIVE: To determine the perception of healthcare professionals (tutors, residents and teaching collaborators) involved in specialist medical training on the core values and skills to develop their tasks. METHODS: A tailor-made questionnaire aimed at healthcare professionals in 9health care centres and a referral hospital. Questionnaire: 4 sections and 51 variables (scale 1-10). RESULTS: A total of 287 professionals participated, which included 97% tutors (n=59), 38% residents (n=61), and 56% others (97 teaching collaborators and 70 not associated with teaching). The alfa Cronbach coefficient was 0.945. Best rated values were work compliance (8.7 points), ethics in professional practice (8.6 points), and respect for their team (8.3 points). The best rated competence was communication with patients and families (8.1 points), followed by self-motivating leadership (7.9 points), and the practical application of medical and healthcare theoretical knowledge (7.8 points). The values received, on average, 0.7 points above competences (95% CI: 0.5-0.9). There were no differences between tutors and residents, although differences were found between doctors and nurses, and between males and females. CONCLUSION: Most of the professionals (tutors, residents, and teaching collaborators) share the same perception of the values and competencies that influence their professional development. This perception was influenced by the professional category and gender, but not age or working in a hospital or primary health care.

The aim of the study was to investigate the epidemiology and clinical features of bloodstream infections due to Escherichia coli producing AmpC ß-lactamases (AmpC-Ec-BSI). In a multi-centre case-control study, all third-generation-cephalosporin-resistant Escherichia coli BSI (3GC-Ec-BSI) isolates were analysed. Acquired bla AmpC (bla ac-AmpC) detection was done by polymerase chain reaction (PCR) and sequencing. Chromosomal bla AmpC (bla c-AmpC) expression was quantified by real-time PCR. Cases were patients with AmpC-Ec-BSI. Controls were patients with cephalosporin-susceptible E. coli BSI, matched 1:1 by sex and age. Demographics, comorbidities, intrinsic and extrinsic risk factors for antimicrobial resistance, clinical presentation and outcomes were investigated. Among 841 E. coli BSI, 17 were caused by AmpC-Ec (2 %). Eleven isolates (58.8 %) had bla ac-AmpC and six were bla c-AmpC overproducers. The mean age of cases was 66.2 years and 71 % were men. Cases were more frequently healthcare-related (82 vs. 52 % controls, p < 0.05) and presented more intrinsic and extrinsic risk factors. At least one risk factor was present in 94.1 % of cases vs. 41.7 % of controls (p = 0.002). Severity and length of stay (LOS) were higher among cases (mean Pitt Score 2.6 vs. 0.38 in controls, p = 0.03; LOS 17.5 days vs. 6 in controls, p = 0.02). Inappropriate empirical therapy (IET) was administered to 70.6 % of cases and 23.5 % of controls (p < 0.003). No differences were found in terms of cure rate at the 14th day and mortality. Bloodstream infections due to AmpC-Ec (mostly plasmid-mediated) are infrequent in our area. AmpC-Ec-BSI affects mainly patients with intrinsic risk factors and those with previous antibiotic exposure. A high proportion received IET.

AIM: To study the influence of prednisone dose during the first month after systemic lupus erythematosus (SLE) diagnosis (prednisone-1) on glucocorticoid burden during the subsequent 11â months (prednisone-2-12). METHODS: 223 patients from the Registro Español de Lupus Eritematoso Sistémico inception cohort were studied. The cumulative dose of prednisone-1 and prednisone-2-12 were calculated and recoded into a four-level categorical variable: no prednisone, low dose (up to 7.5â mg/day), medium dose (up to 30â mg/day) and high dose (over 30â mg/day). The association between the cumulative prednisone-1 and prednisone-2-12 doses was tested. We analysed whether the four-level prednisone-1 categorical variable was an independent predictor of an average dose >7.5â mg/day of prednisone-2-12. Adjusting variables included age, immunosuppressives, antimalarials, methyl-prednisolone pulses, lupus nephritis and baseline SLE Disease Activity Index (SLEDAI). RESULTS: Within the first month, 113 patients (51%) did not receive any prednisone, 24 patients (11%) received average low doses, 46 patients (21%) received medium doses and 40 patients (18%) received high doses. There was a strong association between prednisone-1 and prednisone-2-12 dose categories (p<0.001). The cumulative prednisone-1 dose was directly associated with the cumulative prednisone-2-12 dose (p<0.001). Compared with patients on no prednisone, patients taking medium (adjusted OR 5.27, 95% CI 2.18 to 12.73) or high-dose prednisone-1 (adjusted OR 10.5, 95% CI 3.8 to 29.17) were more likely to receive prednisone-2-12 doses of >7.5â mg/day, while patients receiving low-dose prednisone-1 were not (adjusted OR 1.4, 95% CI 0. 0.38 to 5.2). If the analysis was restricted to the 158 patients with a baseline SLEDAI of ≥6, the model did not change. CONCLUSION: The dose of prednisone during the first month after the diagnosis of SLE is an independent predictor of prednisone burden during the following 11â months.
RESUMEN
OBJECTIVES: To validate the CODEX index in outpatients with advanced chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS: We studied all patients with COPD treated in a chronic respiratory disease unit. We calculated the BODEX and CODEX indices and their relationship with mortality, hospitalisations or both and performed an analysis by number of events (mortality and/or readmissions), using the Cox proportional hazards analysis. RESULTS: We included 80 patients (90% men) with a mean age of 73.4 years. The mean follow-up was 656 days, with an interquartile range (25-75%) of 417-642 days. Seventeen patients died (21%) and 57 (71.3%) required hospitalisation for COPD. The CODEX index was significantly related to mortality (P<.008; HR: 1.56; 95% CI: 1.1-2.15), hospitalisations (P<.01; HR: 1.35; 95% CI: 1.13-1.62) and the combined variable (P<.03; HR: 1.27; 95% CI: 1.1-1.5). The BODEX index was not associated with mortality (P=.17) but was associated with hospitalisation (P<.001; HR: 1.4; 95% CI: 1.15-1.73) and the combined variable (P<.03; HR: 1.2; 95% CI: 1.02-1.34). There were 187 events during follow-up. Both the CODEX (P<.001; HR: 1.17; 95% CI: 1.1-1.27) and BODEX (P<.02; HR: 1.12; 95% CI: 1.02-1.23) indices were related to the number of events. However, after adjusting for the interaction between the 2 indices, only the CODEX index maintained statistical significance for the combined variable for patients (P<.03) and in the analysis by number of events (P<.001). CONCLUSIONS: Both the CODEX and BODEX indices are useful for predicting hospitalisations, although the prognostic ability of the CODEX index is greater than that of the BODEX index, both for mortality and hospitalisations.
RESUMEN
INTRODUCTION AND HYPOTHESIS: The levator ani is the most important muscle in the pelvic floor. This pilot study using 3D power Doppler aimed to identify normal vascularization of the puborectalis/pubovisceralis muscle at its insertion in nulliparous and premenopausal women. METHODS: Forty nulliparous and premenopausal women were evaluated at the Gynecological Unit of a tertiary hospital. All women underwent a translabial ultrasound (US) with 3D power Doppler. Pubic insertion of the puborectalis/pubovisceralis muscle was assessed in the axial plane, and vascularization index (VI), flow index (FI), and vascularization-flow index (VFI) were calculated bilaterally. Volumes were analyzed offline by two independent observers, and interobserver agreement and correlation between variables was calculated. RESULTS: A high, statistically significant, correlation was found between the three US indices on each side (p < 0.005). No correlation was found between the US index and either of the demographic parameters of body mass index [(BMI), p > 0.241], or age (p > 0.398). The degree of correlation between the same index on the different sides was not statistically significant. CONCLUSION: Puborectalis/pubovisceralis muscle vascularization at its insertion can be identified using 3D Doppler US, but values differ substantially from those of the contralateral side.

Systemic sclerosis (SSc) is a complex autoimmune disease which genetic component has not been yet completely understood. IL6 encodes a cytokine with a crucial role in the development of autoimmunity and fibrosis and its actions mainly are controlled by IL-6 receptor (IL-6R). We aimed to investigate whether the functional genetic variants rs8192284 and rs2228044 previously associated with several autoimmune diseases, located within the IL-6 receptor (IL-6R) subunits IL6R and IL6ST genes, respectively, are involved in the susceptibility to SSc and/or its major clinical subphenotypes. A Spanish cohort including 1013 SSc patients and 1375 controls was genotyped using the TaqMan® allelic discrimination technology. SSc patients were subdivided according to the major clinical forms, autoantibody status and presence of fibrotic lung affection. Our data showed no influence of the selected variants in global SSc susceptibility (rs8192284: P=0.67, odds ratios (OR)=0.98; rs2228044: P=0.99, OR=1.00). Similarly, the clinical/autoantibody subphenotype analyses did not yielded significant results. Our data suggest that the analyzed polymorphisms may not play a significant role in the SSc susceptibility.

INTRODUCTION: The aim of our study was to describe the characteristics of bacteremia detected in patients over 79 years and to identify possible factors associated with the mortality. METHODS: A retrospective cohort study, which included all patients over 17 years of age with bacteremia detected between 2004-7 was performed. Demographic variables, comorbidities, source of bacteremia, causing microorganism, severity and hospital mortality were recorded. Patients were classified into three age groups: 18 to 64 years (G1), 65 to 79 (G2) and ≥80 years (G3). RESULTS: We analyzed 1594 episodes of bacteremia (35% in G1, 35% in G2 and 29% in G3). In G3, 47% had renal failure, 83% solid neoplasm, 2% immunosuppression 5% malnutrition and 38% decubitus ulcers. These proportions were 27, 30, 5 and 2%, respectively in G2, and 15, 16, 12 and 5% in G1 (P<.01). The urinary focus accounted for 28%, 43% and 44% in G1, G2 and G3, respectively (P<.01) and biliary focus 6, 11 and 16% (P<.01), in each group. E. coli accounted for 32% in G1, 44% in G2 and 51% in G3. Mortality in each age group was 9, 16 and 21%. In multivariate analysis, mortality in the ≥80 years was associated with renal failure, malnutrition, the presence of ulcers and shock. CONCLUSIONS: Bacteremia in the elderly are mainly of urinary origin. Mortality in these cases depends primarily on the patient's baseline status rather than their age.

OBJECTIVE: To determine the frequency of avulsion of the levator ani muscle in primiparous women according to delivery mode, using introital four-dimensional ultrasonography. METHODS: We performed a prospective observational study at a tertiary obstetric unit. One hundred and eighty primiparous women were included and divided into three groups: normal vaginal delivery without episiotomy, forceps delivery and Cesarean section groups. Between 40 and 120 days after delivery, four-dimensional ultrasonography was performed in order to evaluate the integrity of the levator ani muscle. The operator was blinded to all clinical data and was not aware of delivery mode. The influence of other variables associated with delivery such as birth weight, body mass index, maternal age and use of epidural anesthesia was also studied. RESULTS: Avulsion of the puborectalis component of the levator ani muscle was detected on ultrasonography in 61.7% of women who had undergone a forceps delivery, compared with 13.3% of those who had had a normal vaginal delivery and 0% of those who had had a Cesarean section. Bilateral avulsion was observed in 12/60 (20.0%) of the forceps group and in 2/60 (3.3%) of the normal vaginal delivery group (P < 0.001). Other variables did not seem to influence prevalence. CONCLUSIONS: Forceps delivery is associated with an increased rate of avulsion of the puborectalis component of the levator ani muscle. The effect of forceps use is independent of other delivery-related variables.

BACKGROUND: There is no information about the frequency of liver dysfunction in patients with inflammatory bowel disease (IBD) treated with immunosuppressants and infected with hepatitis B (HBV) and/or C virus (HCV). AIM: To assess the influence of immunosuppressants on the course of HBV and HCV infection in IBD. METHODS: Patients with IBD with HBV and/or HCV infection from 19 Spanish hospitals were included. Clinical records were reviewed for the type of immunosuppressant used, treatment duration, liver function tests and viral markers before, during and after each immunosuppressant. Logistic and Cox regression analysis were used to identify predictors of outcome. RESULTS: 162 patients were included; 104 had HBV markers (25 HBsAg positive) and 74 had HCV markers (51 HCV-RNA positive), and 16 patients had markers of both infections. Liver dysfunction was observed in 9 of 25 HBsAg positive patients (36%), 6 of whom developed hepatic failure. Liver dysfunction in HCV was observed in 8 of 51 HCV-RNA positive patients (15.7%), and only one developed hepatic failure. The frequency and severity of liver dysfunction was significantly higher in HBV-infected patients than in HCV-infected patients (p=0.045 and p=0.049, respectively). Treatment with ≥2 immunosuppressants was an independent predictor of HBV reactivation (OR 8.75; 95% CI 1.16 to 65.66). The majority of patients without reactivation received only one immunosuppressant for a short period and/or prophylactic antiviral treatment. No definite HBV reactivations were found in anti-HBc positive patients lacking HBsAg. CONCLUSION: Liver dysfunction in patients with IBD treated with immunosuppressants is more frequent and severe in those with HBV than in HCV carriers and is associated with combined immunosuppression.

BACKGROUND: Evidence-based international guidelines on chronic obstructive pulmonary disease (COPD), and their corresponding recommendations, were established to improve individual COPD prognosis, and ultimately to improve survival. The aim of this study was to determine whether the long-term mortality after discharge from a COPD hospitalisation has improved recently, and the effect of co-morbidity treatment in improving COPD prognosis. METHODS: In a prospective cohort study design of two cohorts 7 years apart, patients discharged from the same university hospital after a COPD exacerbation were followed-up, and their outcomes compared. Demographic and clinical variables, as well as lung function, were collected with the same protocol by the same investigators. Comprehensive assessments of co-morbidities and treatments were undertaken. Kaplan-Meier survival curves were estimated, and outcomes were compared by means of Cox regression methods. RESULTS: Overall, 135 participants in the 1996-7 cohort and 181 participants in the 2003-4 cohort were studied. Both cohorts were comparable in their baseline demographic and clinical variables, and median follow-up was 439 days. The 3-year mortality was lower in the 2003-4 cohort (38.7%) than in the 1996-7 cohort (47.4%) (p=0.017), and the RR of death after adjustment for gender, age, body mass index, co-morbidities, lung function and mMRC (modified Medical Research Council scale) dyspnoea was 0.66 (95% CI 0.45 to 0.97). Long-term survival improved in the second cohort for patients with COPD with heart failure or cancer (p<0.001). CONCLUSIONS: A recent trend towards better prognosis of patients with COPD after hospital discharge is described and is likely to be associated with better management and treatment of COPD and co-morbidities.

The aim of our study was to analyse the impact of time from onset of symptoms on the systemic cytokine concentrations in patients with pneumococcal pneumonia. Adults with severe pneumococcal pneumonia were prospectively included. At admission, vital signs, time from onset of pneumonia symptoms and circulating levels of C-reactive protein (CRP), serum amyloid A (SAA), tumour necrosis factor (TNF)-alpha, and interleukin (IL)-1beta, IL-6, IL-8, IL-10 and IL-1ra were recorded. 32 patients were included; 13 patients had <48 h of evolution and 19 patients had been sick for >48 h. The group with a longer time of evolution presented higher plasmatic levels of TNF-alpha (19.1+/-8.5 versus 35.5+/-26 pg.mL(-1)), fibrinogen (6+/-1.8 versus 9+/-2); CRP (130+/-85 versus 327+/-131) and SAA (678+/-509 versus 984+/-391). Concentrations of TNF-alpha were associated with the presence of bacteraemia, initial blood pressure <90 mmHg and with a lower oxygen saturation at admission. Likewise, TNF-alpha levels were correlated with concentrations of IL-1beta (r = 0.49), IL-6 (r = 0.41) and IL-8 (r = 0.40). In pneumococcal pneumonia, patients with a longer time of evolution presented with higher levels of pro-inflammatory cytokines and a higher expression of acute phase proteins, suggesting a sustained release of pneumococcal antigens over time.

BACKGROUND: The BODE index can accurately predict mortality in ambulatory patients with COPD, although its utility in hospitalized patients is unknown. MATERIAL AND METHODS: We prospectively evaluated all patients hospitalized during one year for acute exacerbation of COPD with one or more admissions in the previous year. On discharge, previous functional dependence, comorbidity, depression and quality of life, among other variables, were evaluated. Body mass index, 6-minute walking test, dyspnea scale and spirometry with a post-bronchodilator test were performed on the last day of hospitalization and the BODE index was calculated using these data. RESULTS: A total of 66 patients were included, with a mean age of 71.6 +/- 8.9 years. Of these patients, 42 (63.6%) died before the end of the study (median follow-up 1,490 days). A higher mortality was observed among the oldest patients (p < 0.004), those with more comorbidities (p < 0.05), worse score on the BODE index (p < 0.006; OR 1.3; CI 95%: 1.07-1.54) and the dyspnea scale (p < 0.008). Functional dependence (p < 0.02), and pCO2 > 45 mmHg at discharge (p < 0.001) were also significant predictors of mortality. In the multivariate analysis, only hypercapnia (p < 0.004; OR 3.48; CI 95% 1.49-8.14) and the BODE index (p < 0.0005; OR 1.47; CI 95%: 1.18-1.82) were independent predictors of mortality. CONCLUSIONS: The BODE index measured at hospital discharge is an accurate and reliable predictor of mortality in patients who require several admissions for acute exacerbations of COPD.

Risk factors for Pseudomonas aeruginosa (PA) isolation in patients hospitalised for chronic obstructive pulmonary disease (COPD) exacerbation remain controversial. The aim of our study was to determine the incidence and risk factors for PA isolation in sputum at hospital admission in a prospective cohort of patients with acute exacerbation of COPD. We prospectively studied all patients with COPD exacerbation admitted to our hospital between June 2003 and September 2004. Suspected predictors of PA isolation were studied. Spirometry tests and 6-min walking tests were performed 1 month after the patients were discharged. High-resolution computed tomography (HRCT) was performed in a randomised manner in one out of every two patients to quantify the presence and extent of bronchiectasis. Patients were followed up during the following year for hospital re-admissions. A total of 188 patients were included, of whom 31 (16.5%) had PA in sputum at initial admission. The BODE (body mass index, airflow obstruction, dyspnoea, exercise capacity) index (OR 2.18, CI 95% 1.26-3.78; p = 0.005), admissions in the previous year (OR 1.65, CI 95% 1.13-2.43; p = 0.005), systemic steroid treatment (OR 14.7, CI 95% 2.28-94.8; p = 0.01), and previous isolation of PA (OR 23.1, CI 95% 5.7-94.3; p<0.001) were associated with PA isolation. No relationship was seen between bronchiectasis in HRCT and antibiotic use in the previous 3 months. PA in sputum at hospital admission is more frequent in patients with poorer scoring on the BODE index, previous hospital admissions, oral corticosteroids and prior isolation of PA.

The purpose of the study was to compare the clinical characteristics and outcomes of bacteraemic pneumococcal pneumonia (BPP) in chronic obstructive pulmonary disease (COPD) and non-COPD patients. A case-control study was conducted. Cases were any adult with BPP and forced expiratory volume in 1 second (FEV(1)) <80% and FEV(1)/forced expiratory vital capacity (FVC) <70%. Controls were patients with BPP without clinical diagnosis of COPD matched 1:2 by age, gender and date of isolation. Variables included co-morbidities, serotypes, pneumonia severity index (PSI), treatment and mortality. There were 45 cases and 90 controls. No significant differences were found in Charlson scores, antibiotic treatment, serotype distribution and severity. Malignancy, shock and mechanical ventilation were less frequent in COPD patients. One patient died vs 14 controls (p = 0.02). In univariate analysis, shock, multilobar involvement, Charlson score, heart failure and absence of COPD were associated with mortality. After adjustment for the presence of shock there were no differences in mortality. BPP presents less frequently with shock and has a lower mortality rate in COPD patients than in non-COPD patients.
