Utilidad de los enjuagues con povidona yodada y peróxido de hidrógeno en pacientes con COVID-19 / Utility of mouth rinses with povidone-iodine and hydrogen peroxide in patients with COVID-19

Introducción: La povidona yodada y el peróxido de hidrógeno podrían ser eficaces contra el SARS-CoV-2. Métodos: Estudio observacional de seguimiento prospectivo (EPA-AS) en 88 pacientes (43±17 años, 55% varones) con SARS-CoV-2 en muestras nasofaríngeas (RT-PCR). Treinta y uno recibieron enjuagues/gargarismos con povidona yodada cada 8h 2 días consecutivos, 17 con la misma pauta de peróxido de hidrógeno y 40 controles sin enjuagues. Se repitió PCR a los 3, 11 y 17 días. Resultados: Tras la intervención no hubo diferencias en la carga viral: povidona yodada (4,3±2,7 copias/ml), peróxido de hidrógeno (4,6±2,9 copias/ml), controles (4,4±3,0 copias/ml). El porcentaje de pacientes con una 2.ª PCR negativa fue 27% povidona yodada, 23% peróxido de hidrógeno y 32% controles; en la 3.ª PCR 62%, 54% y 58% respectivamente y en la 4.ª PCR, 81%, 75% y 81%. Conclusión: Nuestros resultados no apoyan la utilidad de los enjuagues de estos 2 antisépticos en pacientes con COVID-19.(AU)

Introduction: Povidone-iodine and hydrogen peroxide could be effective in against SARS-CoV-2. Methods: A “non-interventional trial” in 88 patients (43±17 yrs, 55% men) with SARS-CoV-2 in nasopharyngeal swabs (RT-PCR). 31 received mouth rinses/gargling with povidone-iodine (every 8h, two consecutive days), 17 with mouth rinses/gargling of hydrogen peroxide, and 40 controls. PCR were repeated at 3, 11 and 17 days. Results: After intervention the viral load (Log10copies/ml) remained similar in povidone-iodine (4.3±2.7copies/ml), hydrogen peroxide (4.6±2.9copies/ml; p=0.40) and controls (4.4±3.0copies/ml). The percentage of patients with a negative result in the second PCR was 27% in povidone-iodine group, 23% in hydrogen peroxide and 32% in controls; in the third PCR, 62%, 54% and 58% respectively; and in the fourth PCR, 81%, 75% and 81%. Conclusion: Our results do not support the clinical usefulness of mouth rinses/gargling with povidone-iodine or hydrogen peroxide in patients with COVID-19.(AU)

Serum Calcitonin Gene-Related Peptide α and ß Levels are Increased in COVID-19 Inpatients.

BACKGROUND: Vasoactive peptides play an important role in a wide range of physiological and pathological conditions. Due to its known functions, the calcitonin gene-related peptide (CGRP) has been suggested as a possible modulator of the hyperimmune response in COVID-19 and thus, blocking its action may lessen the pulmonary effects of COVID-19. AIM OF THE STUDY: To compare the circulating levels of CGRPα and CGRPß in healthy controls compared to hospitalized COVID-19 patients. The study also analyzed how different comorbidities and treatments may affect these concentrations in cases of COVID-19 infection with pulmonary involvement METHODS: Serum samples were collected from the antecubital vein of 51 control subjects (mean age = 55 ± 14 years; range = 26-77; 56.9% female) and 52 patients hospitalized with COVID-19 infection (mean age = 55 ± 13; range = 23-77; 55.8% female) from December 2020 to May 2021. Enzyme-linked immunosorbent assays (ELISAs) were used for CGRPα (Abbexa, UK) and CGRPß (CUSABIO, China) measurements. Comorbidities, symptoms, and treatments of infection were listed. RESULTS: The results showed that the serum levels of both isoforms of CGRP were significantly higher in patients with COVID-19 (α: 57.9 ± 35.8 pg/mL; ß: 6.1 ± 2.6 pg/mL) compared to controls (α: 41.8 ± 25.4 pg/mL; ß: 4.5 ± 2.4 pg/mL) (p <0.01). Also, the presence of arterial hypertension (HT), obesity, or corticosteroid treatment significantly alter the serum concentration of CGRPα in the subgroups compared to controls. CONCLUSION: The elevated serum CGRP levels found in our COVID-19 group compared to controls may suggest that CGRP plays a role in the pathophysiology of the disease, more specifically, in the cytokine storm and in the pulmonary involvement. Future studies should focus on the source of this CGRP elevation.

Vitamin D Status in Hospitalized Patients with SARS-CoV-2 Infection.

BACKGROUND: The role of vitamin D status in COVID-19 patients is a matter of debate. OBJECTIVES: To assess serum 25-hydroxyvitamin D (25OHD) levels in hospitalized patients with COVID-19 and to analyze the possible influence of vitamin D status on disease severity. METHODS: Retrospective case-control study of 216 COVID-19 patients and 197 population-based controls. Serum 25OHD levels were measured in both groups. The association of serum 25OHD levels with COVID-19 severity (admission to the intensive care unit, requirements for mechanical ventilation, or mortality) was also evaluated. RESULTS: Of the 216 patients, 19 were on vitamin D supplements and were analyzed separately. In COVID-19 patients, mean ±â€…standard deviation 25OHD levels were 13.8 ±â€…7.2 ng/mL, compared with 20.9 ±â€…7.4 ng/mL in controls (P < .0001). 25OHD values were lower in men than in women. Vitamin D deficiency was found in 82.2% of COVID-19 cases and 47.2% of population-based controls (P < .0001). 25OHD inversely correlates with serum ferritin (P = .013) and D-dimer levels (P = .027). Vitamin D-deficient COVID-19 patients had a greater prevalence of hypertension and cardiovascular diseases, raised serum ferritin and troponin levels, as well as a longer length of hospital stay than those with serum 25OHD levels ≥20 ng/mL. No causal relationship was found between vitamin D deficiency and COVID-19 severity as a combined endpoint or as its separate components. CONCLUSIONS: 25OHD levels are lower in hospitalized COVID-19 patients than in population-based controls and these patients had a higher prevalence of deficiency. We did not find any relationship between vitamin D concentrations or vitamin deficiency and the severity of the disease.

Analysis of sex differences in the clinical presentation, management and prognosis of infective endocarditis in Spain.

INTRODUCTION: Sex-dependent differences of infective endocarditis (IE) have been reported. Women suffer from IE less frequently than men and tend to present more severe manifestations. Our objective was to analyse the sex-based differences of IE in the clinical presentation, treatment, and prognosis. MATERIAL AND METHODS: We analysed the sex differences in the clinical presentation, modality of treatment and prognosis of IE in a national-level multicentric cohort between 2008 and 2018. All data were prospectively recorded by the GAMES cohort (Spanish Collaboration on Endocarditis). RESULTS: A total of 3451 patients were included, of whom 1105 were women (32.0%). Women were older than men (mean age, 68.4 vs 64.5). The most frequently affected valves were the aortic valve in men (50.6%) and mitral valve in women (48.7%). Staphylococcus aureus aetiology was more frequent in women (30.1% vs 23.1%; p<0.001).Surgery was performed in 38.3% of women and 50% of men. After propensity score (PS) matching for age and estimated surgical risk (European System for Cardiac Operative Risk Evaluation II (EuroSCORE II)), the analysis of the matched cohorts revealed that women were less likely to undergo surgery (OR 0.74; 95% CI 0.59 to 0.91; p=0.05).The observed overall in-hospital mortality was 32.8% in women and 25.7% in men (OR for the mortality of female sex 1.41; 95% CI 1.21 to 1.65; p<0.001). This statistical difference was not modified after adjusting for all possible confounders. CONCLUSIONS: Female sex was an independent factor related to mortality after adjusting for confounders. In addition, women were less frequently referred for surgical treatment.

Usefulness of the COVID-GRAM and CURB-65 scores for predicting severity in patients with COVID-19.

AIM: The aim of this study was to determine the usefulness of COVID-GRAM and CURB-65 scores as predictors of the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Caucasian patients. METHODS: This was a retrospective observational study including all adults with SARS-CoV-2 infection admitted to Hospital Universitario Marqués de Valdecilla from February to May 2020. Patients were stratified according to COVID-GRAM and CURB-65 scores as being at low-medium or high risk of critical illness. Univariate analysis, multivariate logistic regression models, receiver operating characteristic curve, and area under the curve (AUC) were calculated. RESULTS: A total of 523 patients were included (51.8% male, 48.2% female; mean age 65.63 years (standard deviation 17.89 years)), of whom 110 (21%) presented a critical illness (intensive care unit admission 10.3%, 30-day mortality 13.8%). According to the COVID-GRAM score, 122 (23.33%) patients were classified as high risk; 197 (37.7%) presented a CURB-65 score ≥2. A significantly greater proportion of patients with critical illness had a high COVID-GRAM score (64.5% vs 30.5%; P < 0.001). The COVID-GRAM score emerged as an independent predictor of critical illness (odds ratio 9.40, 95% confidence interval 5.51-16.04; P < 0.001), with an AUC of 0.779. A high COVID-GRAM score showed an AUC of 0.88 for the prediction of 30-day mortality, while a CURB-65 ≥2 showed an AUC of 0.83. CONCLUSIONS: The COVID-GRAM score may be a useful tool for evaluating the risk of critical illness in Caucasian patients with SARS-CoV-2 infection. The CURB-65 score could be considered as an alternative.

We did not find any relationship between vitamin D concentrations or vitamin deficiency and the severity of the disease.

Gentamicin may have no effect on mortality of staphylococcal prosthetic valve endocarditis.

PURPOSE: To analyze the influence of adding gentamicin to a regimen consisting of ß-lactam or vancomycin plus rifampicin on survival in patients suffering from Staphylococcal prosthetic valve endocarditis (SPVE). METHODS: From January 2008 to September 2016, 334 patients with definite SPVE were attended in the participating hospitals. Ninety-four patients (28.1%) received treatment based on ß-lactam or vancomycin plus rifampicin and were included in the study. Variables were analyzed which related to patient survival during admission, including having received treatment with gentamicin. RESULTS: Seventy-seven (81.9%) were treated with cloxacillin (or vancomycin) plus rifampicin plus gentamicin, and 17 patients (18.1%) received the same regimen without gentamicin. The causative microorganism was Staphylococcus aureus in 40 cases (42.6%) and coagulase-negative staphylococci in 54 cases (57.4%). Overall, 40 patients (42.6%) died during hospital admission, 33 patients (42.9%) in the group receiving gentamicin and 7 patients in the group that did not (41.2%, P = 0.899). Worsening renal function was observed in 42 patients (54.5%) who received gentamicin and in 9 patients (52.9%) who did not (p = 0.904). Heart failure as a complication of endocarditis (OR: 4.58; CI 95%: 1.84-11.42) and not performing surgery when indicated (OR: 2.68; CI 95%: 1.03-6.94) increased mortality. Gentamicin administration remained unrelated to mortality (OR: 1.001; CI 95%: 0.29-3.38) in the multivariable analysis. CONCLUSIONS: The addition of gentamicin to a regimen containing vancomycin or cloxacillin plus rifampicin in SPVE was not associated to better outcome.

Daptomycin treatment in Gram-positive vascular graft infections.

BACKGROUND: Daptomycin is a bactericidal antibiotic approved for the treatment of skin and soft tissue infections and right-side endocarditis. However, there is a lack of published data outlining its usefulness in vascular graft infections (VGI). The aim of this study was to describe the clinical experience of daptomycin use in the treatment of VGI caused by Gram-positive bacteria. METHODS: This was a retrospective cohort study of patients diagnosed with VGI receiving daptomycin at a tertiary care hospital during the period January 2010 to December 2012. RESULTS: Of a total 1066 consecutive patients who had undergone vascular grafts (VG), 25 were diagnosed with VGI. Fifteen of these patients (11 prosthetic VG, three autologous VG, one both types) received daptomycin (median dose 6.7mg/kg/day, range 4.1-7.1mg/kg/day; median age 69 years, range 45-83 years; 80% male). The infected bypass was removed in 13 cases. The most common reason for selecting daptomycin was kidney failure (53%). The Gram-positive organisms isolated were coagulase-negative Staphylococcus (n=10), Staphylococcus aureus (n=3) (two methicillin-resistant S. aureus), Enterococcus faecium (n=2), and Enterococcus faecalis (n=1). The mean follow-up was 69 months (interquartile range 48-72 months). Ten patients (66.7%) achieved complete healing of the VGI. A recurrence of the infection was observed in 100% of patients in whom the bypass was not removed. Among patients who did not achieve complete healing, one needed a supracondylar amputation and one died as a consequence of infection. Five patients received treatment with rifampicin in addition to daptomycin and they were all cured. CONCLUSIONS: The use of daptomycin and surgery for Gram-positive VGI was effective and well tolerated, and this may be a good alternative for the treatment of VGI in patients with peripheral arterial disease in whom renal insufficiency is common.

Infective endocarditis in patients with cancer: a consequence of invasive procedures or a harbinger of neoplasm?: A prospective, multicenter cohort.

The aim of the study was to draw a comparison between the characteristics of infective endocarditis (IE) in patients with cancer and those of IE in noncancer patients.Patients with IE, according to the modified Duke criteria, were prospectively included in the GAMES registry between January 2008 and February 2014 in 30 hospitals. Patients with active cancer were compared with noncancer patients.During the study period, 161 episodes of IE fulfilled the inclusion criteria. We studied 2 populations: patients whose cancer was diagnosed before IE (73.9%) and those whose cancer and IE were diagnosed simultaneously (26.1%). The latter more frequently had community-acquired IE (67.5% vs 26.4%, P < .01), severe sepsis (28.6% vs 11.1%, P = .013), and IE caused by gastrointestinal streptococci (42.9% vs 16.8%, P < .01). However, catheter source (7.1% vs 29.4%, P = .003), invasive procedures (26.2% vs 44.5%, P = .044), and immunosuppressants (9.5% vs 35.6%, P = .002) were less frequent.When compared with noncancer patients, patients with cancer were more often male (75.2% vs 67.7%, P = .049), with a higher comorbidity index (7 vs 4). In addition, IE was more often nosocomial (48.7% vs 29%) and originated in catheters (23.6% vs 6.2%) (all P < .01). Prosthetic endocarditis (21.7% vs 30.3%, P = .022) and surgery when indicated (24.2% vs 46.5%, P < .01) were less common. In-hospital mortality (34.8% vs 25.8%, P = .012) and 1-year mortality (47.8% vs 30.9%, P < .01) were higher in cancer patients, although 30-day mortality was not (24.8% vs 19.3%, P = .087).A significant proportion of cases of IE (5.6%) were recorded in cancer patients, mainly as a consequence of medical interventions. IE may be a harbinger of occult cancer, particularly that of gastrointestinal or urinary origin.

[Hydatidosis: epidemiological, clinical, diagnostic and therapeutic aspects]. / Hidatidosis: aspectos epidemiológicos, clínicos, diagnósticos y terapéuticos.

Hydatidosis or cystic echinococcosis (CE) is a parasitic zoonosis caused by Echinococcus granulosus. Its life cycle involves dogs, sheep and sometimes other animals. CE has a worldwide distribution, with greater prevalence in temperate zones. In Spain, Castile and León, La Rioja, Navarre, Aragón, and the Mediterranean coast are the areas where it is most commonly diagnosed, although there have also been published cases in other regions, such as Cantabria. Clinical signs and symptoms of EC may be related to the mass effect of the cyst, its superinfection or anaphylactic reactions secondary to its rupture. Because of its slow growth, diagnosis is usually made in adulthood by combining clinical symptoms with imaging and serological tests. There is no universal consensus on the management of CE. Treatment is based mainly on three pillars: medical treatment (mainly albendazole), surgery, and percutaneous drainage. The choice of the most appropriate approach is based on the patient's symptoms and the characteristics of the cysts.

Hidatidosis: aspectos epidemiológicos, clínicos, diagnósticos y terapéuticos / Hydatidosis: epidemiological, clinical, diagnostic and therapeutic aspects

La hidatidosis o equinococosis quística (EQ) es una zoonosis parasitaria causada por Echinococcus granulosus. Su ciclo vital incluye perros, ovejas y otros animales. La EQ tiene distribución mundial, con mayor prevalencia en zonas templadas. En España, Castilla y León, La Rioja, Navarra, Aragón y la costa mediterránea son las áreas donde se diagnostica más frecuentemente, aunque también se han publicado casos en otras regiones, como Cantabria. Los signos y síntomas de la EQ pueden deberse al efecto masa del quiste, su sobreinfección o reacciones de anafilaxia secundarias a su ruptura. Debido a su lento crecimiento, el diagnóstico habitualmente se realiza en la edad adulta, mediante los síntomas clínicos y las pruebas de imagen y serológicas. No hay consenso universal respecto al tratamiento de la EQ. Éste se basa en tres pilares fundamentales: cirugía, drenaje percutáneo y antiparasitarios (habitualmente albendazol). La elección del tratamiento más apropiado se basa en la sintomatología del paciente y las características del quiste (AU)

Self-administered outpatient parenteral antimicrobial therapy (S-OPAT) for infective endocarditis: a safe and effective model.

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.

Pandemic 2009 A(H1N1) infection requiring hospitalization of elderly Spanish adults.

OBJECTIVES: To describe the clinical presentation and prognosis of elderly adults hospitalized with pandemic 2009 A(H1N1) influenza infection and to compare these data with those of younger patients. DESIGN: Prospective, observational, multicenter study. SETTING: Thirteen hospitals in Spain. PARTICIPANTS: Adults admitted to the hospital with confirmed pandemic 2009 A(H1N1) influenza infection. MEASUREMENTS: Demographic, clinical, laboratory, radiological, and outcome variables. RESULTS: Between June 12 and November 10, 2009, 585 adults with confirmed 2009 A(H1N1) influenza were hospitalized, of whom 50 (8.5%) were aged 65 and older (median age 72, range 65-87). Older adults (≥ 65) were more likely to have associated comorbidities (88.0% vs 51.2%; P < .001), primarily chronic pulmonary diseases (46.0% vs 27.3%; P < .001). Lower respiratory tract symptoms and signs such as dyspnea (60.0% vs 45.6%) and wheezing (46.0% vs 27.8%; P = .007) were also more common in these elderly adults, although pulmonary infiltrates were present in just 14 (28.0%) of the older adults, compared with 221 (41.3%) of the younger adults (P = .06). Multilobar involvement was less frequent in elderly adults with pulmonary infiltrates than younger adults with pulmonary infiltrates (21.4% vs 60.0%; P = .05). Rhinorrhea (4.0% vs 21.9%; P = .003), myalgias (42.0% vs 59.1%; P = .01), and sore throat (14.0% vs 29.2%; P = .02) were more frequent in younger adults. Early antiviral therapy (<48 hours) was similar in the two groups (34.0% vs 37.9%; P = .58). Two older adults (4.0%) died during hospitalization, compared with 11 (2.1%) younger adults (P = .30). CONCLUSION: Elderly adults with 2009 A(H1N1) influenza had fewer viral-like upper respiratory symptoms than did younger adults. Pneumonia was more frequent in younger adults. No significant differences were observed in hospital mortality.

Clinical characteristics and outcome of patients with pandemic 2009 Influenza A(H1N1)v virus infection admitted to hospitals with different levels of health-care.

BACKGROUND: The outcome of patients with influenza A 2009 (H1N1)v virus infection taking into account hospital type has not been elucidated. OBJECTIVES: To compare risk factors, clinical features and outcome of patients admitted to 3 public hospitals with different levels of health-care. METHODS: Prospective study of all non-pregnant adult patients admitted to 3 hospitals with pandemic H1N1 infection, from June 1 to December 31 and followed up until 1 month after discharge. RESULTS: During the study period, 111 patients with a mean age of 49 years (15-89) were hospitalized: 52 in hospital 1 (900-bed tertiary-teaching-hospital), 33 in hospital 2 (315-beds secondary-hospital) and 26 in hospital 3 (150-beds primary-care-hospital).Overall 80% of patients had at least 1 comorbid condition with no differences between hospitals. Symptoms or signs on admission were similar except for cough (P=0.01) more frequent in patients in hospital 1 and dyspnea (P=0.05), myalgia, arthralgia (P=0.04) and hypoxemia (P=0.009) present in more patients in hospital 2. In-hospital mortality rates were not statistically different between hospitals. In the stepwise analysis, independent predictors of mortality were pneumonia on admission (adjusted OR=8.68, 95%CI 1.0-82.43) and cardiac complications during hospitalization (adjusted OR=13.2, 95%CI 1.67-103.98). CONCLUSIONS: Mortality of patients with pandemic H1N1 infection was influenced by patients underlying conditions, severity of disease (pneumonia) on admission and complications during hospitalization. Hospital-characteristics do not appear to have influenced severe outcome.

Introducción. La evolución de los pacientes con infección por el virus de la influenza A (H1N1)v 2009, teniendo en cuenta el tipo de hospital donde ingresan no ha sido estudiada. Objetivos. Comparar las características clínicas y la evolución de los pacientes con infección por el virus pandémico influenza A (H1N1)v 2009, teniendo en cuenta el tipo de hospital donde ingresan. Métodos. Estudio prospectivo de todos los pacientes que ingresaron en 3 hospitales públicos con diferentes niveles de atención de salud con infección por el virus pandémico influenza A (H1N1)v entre el 1 de junio y el 31 de diciembre de 2009. Se excluyeron las mujeres embarazadas. Resultados. Durante el período de estudio ingresaron 111 pacientes (edad media de 49 años; rango: 15-89): 52 en el hospital 1 (hospital universitario de 900 camas), 33 en el hospital 2 (315 camas) y 26 en el hospital 3 (150 camas). El 81% de los pacientes tenían al menos 1 enfermedad de base. Los síntomas o signos al ingreso fueron similares, excepto para la tos (P=0,01) más frecuente en los pacientes ingresados en el hospital 1 y disnea (P=0,05), mialgia, artralgia (P=0,04) e hipoxemia (P=0,009) presentes en más pacientes en el hospital 2. No hubo diferencias estadísticamente significativas en la tasa de mortalidad entre los pacientes ingresados en los 3 hospitales. En el análisis multivariante la neumonía al ingreso (OR ajustada=8,68; CI95% 1,0-82,43) y las complicaciones cardiacas durante la hospitalización (OR ajustada=13,2; CI95% 1,67-103,98) fueron predictores independientes de mortalidad. Conclusiones. La mortalidad de los pacientes con infección por el virus de la gripe nueva (H1N1)v 2009 se relacionó la comorbilidad de los pacientes, la gravedad de la enfermedad (neumonía) al ingreso y las complicaciones durante la hospitalización. Las características del hospital donde ingresaron los pacientes no influyeron en su evolución(AU)

Background. The outcome of patients with influenza A 2009 (H1N1)v virus infection taking into account hospital type has not been elucidated. Objectives. To compare risk factors, clinical features and outcome of patients admitted to 3 public hospitals with different levels of health-care. Methods: Prospective study of all non-pregnant adult patients admitted to 3 hospitals with pandemic H1N1 infection, from June 1 to December 31 and followed up until 1 month after discharge. Results. During the study period, 111 patients with a mean age of 49 years (15-89) were hospitalized: 52 in hospital 1 (900-bed tertiary-teaching-hospital), 33 in hospital 2 (315-beds secondary-hospital) and 26 in hospital 3 (150-beds primary-care-hospital).Overall 80% of patients had at least 1 comorbid condition with no differences between hospitals. Symptoms or signs on admission were similar except for cough (P=0.01) more frequent in patients in hospital 1 and dyspnea (P=0.05), myalgia, arthralgia (P=0.04) and hypoxemia (P=0.009) present in more patients in hospital 2. In-hospital mortality rates were not statistically different between hospitals. In the stepwise analysis, independent predictors of mortality were pneumonia on admission (adjusted OR=8.68, 95%CI 1.0-82.43) and cardiac complications during hospitalization (adjusted OR=13.2, 95%CI 1.67-103.98). Conclusions. Mortality of patients with pandemic H1N1 infection was influenced by patients underlying conditions, severity of disease (pneumonia) on admission and complications during hospitalization. Hospital-characteristics do not appear to have influenced severe outcome(AU)
