Estimation of Admission D-dimer Cut-off Value to Predict Venous Thrombotic Events in Hospitalized COVID-19 Patients: Analysis of the SEMI-COVID-19 Registry.

BACKGROUND: Venous thrombotic events (VTE) are frequent in COVID-19, and elevated plasma D-dimer (pDd) and dyspnea are common in both entities. OBJECTIVE: To determine the admission pDd cut-off value associated with in-hospital VTE in patients with COVID-19. METHODS: Multicenter, retrospective study analyzing the at-admission pDd cut-off value to predict VTE and anticoagulation intensity along hospitalization due to COVID-19. RESULTS: Among 9386 patients, 2.2% had VTE: 1.6% pulmonary embolism (PE), 0.4% deep vein thrombosis (DVT), and 0.2% both. Those with VTE had a higher prevalence of tachypnea (42.9% vs. 31.1%; p = 0.0005), basal O2 saturation <93% (45.4% vs. 33.1%; p = 0.0003), higher at admission pDd (median [IQR]: 1.4 [0.6-5.5] vs. 0.6 [0.4-1.2] µg/ml; p < 0.0001) and platelet count (median [IQR]: 208 [158-289] vs. 189 [148-245] platelets × 109/L; p = 0.0013). A pDd cut-off of 1.1 µg/ml showed specificity 72%, sensitivity 49%, positive predictive value (PPV) 4%, and negative predictive value (NPV) 99% for in-hospital VTE. A cut-off value of 4.7 µg/ml showed specificity of 95%, sensitivity of 27%, PPV of 9%, and NPV of 98%. Overall mortality was proportional to pDd value, with the lowest incidence for each pDd category depending on anticoagulation intensity: 26.3% for those with pDd >1.0 µg/ml treated with prophylactic dose (p < 0.0001), 28.8% for pDd for patients with pDd >2.0 µg/ml treated with intermediate dose (p = 0.0001), and 31.3% for those with pDd >3.0 µg/ml and full anticoagulation (p = 0.0183). CONCLUSIONS: In hospitalized patients with COVID-19, a pDd value greater than 3.0 µg/ml can be considered to screen VTE and to consider full-dose anticoagulation.

Health-related quality of life in nonvalvular atrial fibrillation patients with controlled or uncontrolled anticoagulation status.

BACKGROUND: There is a dearth of evidence regarding Health-Related Quality of Life (HRQoL) in nonvalvular atrial fibrillation (NVAF) patients undergoing oral anticoagulation therapy. Our objective was to describe HRQoL in NVAF patients on oral anticoagulation, focusing on uncontrolled patients on vitamin K antagonists (VKAs) versus controlled patients on VKAs or non-vitamin K antagonist oral anticoagulants (NOACs), in a real-world setting. Additionally, we assessed the clinical characteristics of patients with uncontrolled anticoagulation. METHODS: An observational, multicentre, and cross-sectional study, enrolling 38 Spanish Hospitals' Internal Medicine Departments. HRQoL was assessed using the validated Spanish version of the Sawicki questionnaire. High self-perceived HRQoL was indicated by high scores in the general treatment satisfaction and self-efficacy dimensions, and by low scores in the strained social network, daily hassles and distress dimensions. RESULTS: Five hundred and one patients were included for assessment. Mean scores ± SD were closer to a high perceived HRQoL in controlled than uncontrolled patients for the five dimensions of the questionnaire: 4.9 ± 1.0 versus 3.6 ± 1.3 for general treatment satisfaction; 4.3 ± 1.0 versus 3.6 ± 1.0 for self-efficacy, 3.1 ± 0.9 versus 3.9 ± 1.1 for strained social network, 2.1 ± 0.8 versus 3.0 ± 1.0 for daily hassles and 1.8 ± 0.9 versus 2.6 ± 1.2 for distress. CONCLUSIONS: HRQoL in patients with controlled anticoagulant status treated with NOACs or VKAs was better than in patients with uncontrolled anticoagulant status. This seems to indicate that anticoagulation control status influences perception of HRQoL, highlighting the importance of its evaluation when assessing HRQoL in NVAF patients.

Factors related to NT-proBNP levels in HIV patients aged over 40 years.

OBJECTIVE: To determine the levels of NT-pro BNP in HIV patients over 40 years who are receiving highly active antiretroviral therapy (HAART) and investigating potential independent clinical or laboratory factors. METHOD: We determine levels of NT-pro BNP in peripheral blood of HIV patients from Costa del Sol Hospital, over 40 years. We collected epidemiological, classical cardiovascular risk factors and variables associated with HIV infection status. The qualitative variables were compared using the χ2 test. NT-proBNP levels were taken as the dependent variable. The association between these levels and the quantitative variables were studied by analysis of variance (ANOVA), and the association with the qualitative variables, using Student's t test. RESULTS: Nt-pro BNP levels were determined in 146 HIV patients. We assess the 10-year cardiovascular risk calculated by the Framingham equation, 59 (41.5%) were classified as low risk, 46 (32.4%) as a moderate risk and 37 (26.1%) as a high risk. The higher levels of NT-pro BNP were found in women, and in those patient with lower filtration rate and high levels of triglycerides. An association was also observed between higher levels of NT-proBNP and the recent use of lamivudine and fosamprenavir. After a multivariate analysis we found an association between higher levels of NT-proBNP and the current use of fosamprenavir and a lower glomerular filtration rate. CONCLUSIONS: We found, with the limitations of a small serie, that higher levels of NTproBNP in HIV patients could be linked to the occurrence of cardiovascular events, this fact suggest that NTpro BNP could be used in patients at moderate or high vascular risk in order to optimise the primary prevention of vascular events.

Increase in hospital care at the end of life: Retrospective analysis of the last 20 years of life of a cohort of patients.

BACKGROUND: There is an increasing need for end-of-life care due to society's progressive aging. This study aimed to describe how hospitalizations evolve long-term and in the last months life of a cohort of deceased patients. METHODS: The study population were those who died in one year who lived in a district in southern Spain. The number of hospital stays over the previous 20 years and number of contacts with the emergency department, hospitalization, outpatient clinics, and medical day hospital in the last three months of life were determined. The analyses were stratified by age, sex, and pattern of functional decline. RESULTS: The study population included 1773 patients (82.5% of all who died in the district). The hospital stays during the last 20 years of life were concentrated in the last five years (66%) and specially in the last six months (32%). Eighty percent had contact with the hospital during their last three months of life. The older group had the minimun of stays over the last 20 years and contacts with the hospital in the last months of life. CONCLUSIONS: The majority of hospitalizations occur at the end of life and these admissions represent a significant part of an acute-care hospital's activity. The progressive prolongation of life does not have to go necessarily along with a proportional increase in hospital stays.

Seroprevalence of antibodies to the influenza A (H1N1) virus among healthcare workers prior to the 2009 pandemic peak.

OBJECTIVE: Our aim was to study the proportion of healthcare workers with a positive serology for Influenza A(H1N1)2009 without having flu, in a Spanish hospital at the beginning of the pandemic. METHODS: A survey study carried out during August 2009 (before the peak of the pandemic in Spain) in the Hospital Costa del Sol, a second level hospital with almost 300 beds in the South of Spain. The participants were workers in the following hospital units: Emergencies, Medical Area (Internal Medicine, Chest Diseases), Surgical Area (General Surgery and Anaesthesia) of any professional category. A study was made of the proportion of healthcare workers in our hospital with positive serology for the new influenza A (H1N1)2009 virus, as determined by the haemagglutination inhibition technique (≥1/40). The subjects completed a health status questionnaire, and provided a blood sample for serology testing. RESULTS: A total of 239 workers participated, of whom 25.1% had positive serology. The hospital area in which most individuals had positive serology was the Emergency Department (36.6%), while the professional category in which most individuals with a positive serology worked was that of the orderlies (41.7%). CONCLUSION: Around 25% of healthcare workers in our hospital had positive serology before the peak of the pandemic, none of them had received vaccine for Influenza A (H1N1) 2009 or had been diagnosed of influenza previously.

Epidemiology of atrial fibrillation-related ischemic stroke and its association with DOAC uptake in Spain: first national population-based study 2005 to 2018.

INTRODUCTION AND OBJECTIVES: The incidence and prevalence of atrial fibrillation (AF), a major risk factor for stroke, has increased substantially in the past few years. However, several studies have reported a decline in AF-related stroke rates associated with higher uptake of direct oral anticoagulants (DOACs). This ecological study evaluated the association between DOAC uptake in Spain and the incidence rate (IR) of AF-related ischemic stroke. METHODS: Data were obtained from the Registry of Activity of Specialized Healthcare of the Spanish Ministry of Health (RAE-MDS). AF-related ischemic strokes were identified using International Classification of Diseases codes. IR were age-standardized and adjusted to the 2013 European standard population. Poisson regression models were used to identify the association between DOAC uptake and AF-related ischemic stroke in patients aged ≥ 65 years. RESULTS: Before the use of DOACs, the adjusted IR of AF-related ischemic stroke increased steadily from 2005 (IR=2.20 per 100 000 person/y) to 2012 (IR=2.67). Upon DOAC uptake in Spain from 2012 onwards for AF-related ischemic stroke prevention, the IR remained constant or decreased slightly (IR in 2018=2.66). Poisson regression showed that DOAC uptake was a significant predictor for the rate of AF-related ischemic stroke in patients older than 65 years (IRR=0.995; 95%CI, 0.995-0.996). CONCLUSIONS: This study shows an association between DOAC use and a reduced incidence of AF-related ischemic stroke. While this association is based on aggregate data and cannot demonstrate causality, these findings suggest that higher DOAC uptake could improve health outcomes in AF patients in Spain.

Role of telemedicine in the management of oral anticoagulation in atrial fibrillation: a practical clinical approach.

Compared with face-to-face consultations, telemedicine has many advantages, including more efficient use of healthcare resources, partial relief of the burden of care, reduced exposure to COVID-19, treatment adjustment, organization of more efficient healthcare circuits and patient empowerment. Ensuring optimal anticoagulation in atrial fibrillation patients is mandatory if we want to reduce the thromboembolic risk. Of note, telemedicine is an excellent option for the long-term management of atrial fibrillation patients. Moreover, direct oral anticoagulants may provide an added value in telemedicine (versus vitamin K antagonists), as it is not necessary to monitor anticoagulant effect or make continuous dosage adjustments. In this multidisciplinary consensus document, the role of telemedicine in anticoagulation of this population is discussed and practical recommendations are provided.

Coronavirus disease 2019 hospitalization outcomes in persons with and without HIV in Spain.

OBJECTIVE: To compare coronavirus disease 2019 (COVID-19) hospitalization outcomes between persons with and without HIV. DESIGN: Retrospective observational cohort study in 150 hospitals in Spain. METHODS: Patients admitted from 1 March to 8 October 2020 with COVID-19 diagnosis confirmed by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 positive) PCR test in respiratory tract samples. The primary data source was the COVID-19 Sociedad Española de Medicina Interna's registry (SEMI-COVID-19). Demographics, comorbidities, vital signs, laboratory parameters, and clinical severity as well as treatments received during admission, treatment duration, ICU admission, use of invasive mechanical ventilation, and death were recorded. Factors associated with mortality and the composite of ICU admission, invasive mechanical ventilation, and death, were analyzed. RESULTS: Data from 16 563 admissions were collected, 98 (0.59%) of which were of persons with HIV infection. These patients were younger, the percentage of male patients was higher, and their Charlson comorbidity index was also higher. Rates of mortality and composite outcome of ICU admission, invasive mechanical ventilation or death were lower among patients with HIV infection. In the logistic regression analysis, HIV infection was associated with an adjusted odds ratio of 0.53 [95% confidence interval (CI) 0.29-0.96] for the composite outcome. CONCLUSION: HIV infection was associated with a lower probability of ICU admission, invasive mechanical ventilation, or death.

[Ankle-brachial index in the assessment of cardiovascular risk among HIV infected patients]. / Uso del índice tobillo-brazo en la reclasificación del riesgo vascular en pacientes con infección VIH.

BACKGROUND: Vascular risk is an important cause of morbidity and mortality in HIV infected patients. AIM: To study the value of the ankle-brachial index (ABI) in vascular risk stratification in a cohort of people with HIV infection. PATIENTS AND METHODS: Vascular risk was calculated in all the patients that agreed to participate in the study and clinical reports were reviewed retrospectively. Ten year risk of fatal myocardial infarction was calculated according to Framingham equation, National Cholesterol Education Program (NCEP) III and Systematic Coronary Risk Evaluation (SCORE) project score. ABI was calculated measuring resting systolic blood pressure at the ankle, that was compared with the systolic brachial pressure. The ratio of the two pressures defined ABI, that was considered abnormal if it was ≤ 0.9 or ≥ 1.3. RESULTS: A total of 231 HIV infected patients aged 23 to 82 years (80% males) were enrolled. Ten years risk according to Framingham equation was 8.4%, 95% confidence intervals (CI): 7.54-9.15 and according to SCORE scale was 0.8%, 95% CI: 0.62-1.01. According to NCEP III 9% of patients had a high or very high cardiovascular risk. Median ABI was 1.17 (95% CI intervals: 1.16-1.19) and 58 patients (25%) had an abnormal value. Using ABI results, approximately 20% of patients were re-classified as having a high vascular risk. CONCLUSIONS: ABI identified approximately 20% of this cohort of HIV infected subjects as having high vascular risk.

Calcifediol Treatment and Hospital Mortality Due to COVID-19: A Cohort Study.

CONTEXT: Calcifediol has been proposed as a potential treatment for COVID-19 patients. OBJECTIVE: To compare the administration or not of oral calcifediol on mortality risk of patients hospitalized because of COVID-19. DESIGN: Retrospective, multicenter, open, non-randomized cohort study. SETTINGS: Hospitalized care. PATIENTS: Patients with laboratory-confirmed COVID-19 between 5 February and 5 May 2020 in five hospitals in the South of Spain. INTERVENTION: Patients received calcifediol (25-hydroxyvitamin D3) treatment (0.266 mg/capsule, 2 capsules on entry and then one capsule on day 3, 7, 14, 21, and 28) or not. MAIN OUTCOME MEASURE: In-hospital mortality during the first 30 days after admission. RESULTS: A total of 537 patients were hospitalized with COVID-19 (317 males (59%), median age, 70 years), and 79 (14.7%) received calcifediol treatment. Overall, in-hospital mortality during the first 30 days was 17.5%. The OR of death for patients receiving calcifediol (mortality rate of 5%) was 0.22 (95% CI, 0.08 to 0.61) compared to patients not receiving such treatment (mortality rate of 20%; p < 0.01). Patients who received calcifediol after admission were more likely than those not receiving treatment to have comorbidity and a lower rate of CURB-65 score for pneumonia severity ≥ 3 (one point for each of confusion, urea > 7 mmol/L, respiratory rate ≥ 30/min, systolic blood pressure < 90 mm Hg or diastolic blood pressure ≤ 60 mm Hg, and age ≥ 65 years), acute respiratory distress syndrome (moderate or severe), c-reactive protein, chronic kidney disease, and blood urea nitrogen. In a multivariable logistic regression model, adjusting for confounders, there were significant differences in mortality for patients receiving calcifediol compared with patients not receiving it (OR = 0.16 (95% CI 0.03 to 0.80). CONCLUSION: Among patients hospitalized with COVID-19, treatment with calcifediol, compared with those not receiving calcifediol, was significantly associated with lower in-hospital mortality during the first 30 days. The observational design and sample size may limit the interpretation of these findings.

Early use of tocilizumab in patients with severe pneumonia secondary to severe acute respiratory syndrome coronavirus 2 infection and poor prognostic criteria: Impact on mortality rate and intensive care unit admission.

ABSTRACT: The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2, keeps spreading globally. Evidence suggests that a subgroup of patients with severe symptomatology might have cytokine storms, which increases mortality. The use of interleukin-6 (IL-6) inhibitors may help in controlling the pathological immune response to the virus. Tocilizumab, a monoclonal antibody against IL-6, stands as an optional treatment for COVID-19 patients presenting this inflammatory hyper-response.We conducted a retrospective, observational, cohort study including 50 patients affected by COVID-19 with severe pneumonia and poor prognosis criteria, who have also undergone standard treatment; 36 of these patients additionally received tocilizumab in an early stage. The need for intensive care unit (ICU) admission, mortality, recovery of respiratory function, and improvement of biochemical and hematological parameters were compared between cohorts.Most patients were men, non-smokers and the most frequently reported comorbidities were hypertension and diabetes. Recurrent symptoms were fever, cough, and dyspnoea. 54.8% of patients from the tocilizumab group needed intubation, while in the control group 85.7% needed it. Treatment with tocilizumab significatively increased IL-6 levels, (554.45; CI 95% 186.69, 1032.93; P < .05) while C-reactive protein mean levels were reduced (-108.19; CI 95% -140.15, -75.33; P < .05), but no significant difference was found between cohorts. In comparison with the controls, tocilizumab reduced mortality (25.0% vs 42.9%, P = .021) and the number of ICU admissions (63.9% vs 100.0%, P = .021). 44.1% of patients treated with tocilizumab showed favorable radiological evolution, when compared with 15.4% of patients from the control group.Tocilizumab may improve clinical symptoms and mitigate deterioration observed in severe COVID-19 patients, and could be considered as an effective therapeutic option in subjects experiencing a significant inflammatory response to the disease.

[Factors associated with an abnormal ankle-braquial index in a cohort of patients with HIV-1 infection]. / Factores asociados a índice tobillo-brazo alterado en una cohorte de pacientes con infección por el virus de la inmunodeficiencia humana de tipo 1.

INTRODUCTION AND OBJECTIVES: An abnormal ankle-braquial index (ABI) has been related to a higher vascular mortality in the general population. People with HIV infection have a higher prevalence of abnormal ABI than general population. Our aim was to study that prevalence in a cohort of patients with HIV chronic infection and associated factors with an abnormal ABI. METHODS: ABI was calculated consecutively in all the patients who agreed to participate. Abnormal ABI was defined as that lower than 0.9 or higher than 1.3. Demographic variables and those related to vascular risk, HIV infection status and antiretroviral therapy were assessed. RESULTS: 231 patients collaborated in the study, and 25% of them had abnormal ABI (<0.9 in only 3 patients). Age, hypertension, lipid lowering agents use, vascular risk using Framingham equation, proportion of AIDS, CD4 nadir, years with the infection and protease inhibitors use were greater in the group with abnormal ABI. In logistic regression, lipid lowering agents use (OR: 0.39, CI95%: 0.16-0.94) and protease inhibitors use (OR: 2.59, CI95%: 1.33-5.05) remained in the model. CONCLUSION: Protease inhibitors use is associated with abnormal ABI, overall with an ABI greater than 1.3.

Search for asymptomatic carriers of SARS-CoV-2 in healthcare workers during the pandemic: a Spanish experience.

BACKGROUND: Asymptomatic carriers of SARS-CoV-2 can be a vehicle for transmission of the infection. This fact is of particular importance in the case of healthcare workers (HCWs). DESIGN: Cross-sectional study in HCWs in a medium size hospital in the South of Spain. METHODS: between April 15 and 25, 2020, naso and oropharyngeal PCR determination was performed together with IgG and IgM antibody determination by immunochromatography to the HCWs of the Costa del Sol Hospital in Marbella of the units involved in patient care with CoVID-19: Emergencies, Intensive Care and Anesthesia, Internal Medicine and Pneumology. Other units not directly involved in the care of these patients were offered to participate. On the day of sampling, a health questionnaire was answered, reporting symptoms on the same day and in the previous fourteen days. RESULTS: 498 HCWs were studied. Two individuals were detected with PCR for SARS-CoV-2 positive. Both were asymptomatic on the day of sampling, but one of them had had a CoVID-19 compatible picture in the previous two weeks and had positive IgG and IgM; therefore, only one subject was truly asymptomatic carrier (0.2%). 9 workers with positive IgG (1.8%) were detected. CONCLUSIONS: the prevalence of asymptomatic carriers among health workers of the services directly involved in the care of patients with CoVID-19 was very low in our center. This type of strategy can be one more tool in controlling the pandemic.

Reducing residual thrombotic risk in patients with peripheral artery disease: impact of the COMPASS trial.

Patients with peripheral artery disease (PAD) are at a high risk not only for the classical cardiovascular (CV) outcomes (major adverse cardiovascular events; MACE) but also for vascular limb events (major adverse limb events; MALE). Therefore, a comprehensive approach for these patients should include both goals. However, the traditional antithrombotic approach with only antiplatelet agents (single or dual antiplatelet therapy) does not sufficiently reduce the risk of recurrent thrombotic events. Importantly, the underlying cause of atherosclerosis in patients with PAD implies both platelet activation and the initiation and promotion of coagulation cascade, in which Factor Xa plays a key role. Therefore, to reduce residual vascular risk, it is necessary to address both targets. In the Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) trial that included patients with stable atherosclerotic vascular disease, the rivaroxaban plus aspirin strategy (versus aspirin) markedly reduced the risk of both CV and limb outcomes, and related complications, with a good safety profile. In fact, the net clinical benefit outcome composed of MACE; MALE, including major amputation, and fatal or critical organ bleeding was significantly reduced by 28% with the COMPASS strategy, (hazard ratio: 0.72; 95% confidence interval: 0.59-0.87). Therefore, the rivaroxaban plus aspirin approach provides comprehensive protection and should be considered for most patients with PAD at high risk of such events.

Residual risk reduction opportunities in patients with chronic coronary syndrome. Role of dual pathway inhibition.

INTRODUCTION: In this review, the role of the rivaroxaban-plus-aspirin approach (dual pathway inhibition - DPI) in patients with chronic coronary syndrome (CCS) and to perform practical recommendations about its use was updated. AREAS COVERED: The contents of this review were proposed in an expert meeting. To identify relevant articles, a systematic search of Medline/Embase was performed (to July 2019), using the key words 'rivaroxaban', 'vascular dose', 'COMPASS' and 'coronary artery disease' in the search strategy. EXPERT OPINION: Despite current antithrombotic strategies (single/dual antiplatelet therapy) have decreased rates of recurrent cardiovascular events among patients with CCS, residual risk remains unacceptably high. The COMPASS trial showed in CCS patients that compared with aspirin 100 mg rivaroxaban 2.5 mg bid plus aspirin 100 mg reduced the risk of major cardiac events, cardiovascular hospitalization and mortality, without an increase of intracranial or fatal bleedings. Importantly, residual risk with the rivaroxaban plus aspirin approach was lower than with different dual antiplatelet therapy regimens. The rivaroxaban plus aspirin strategy is of particular benefit in patients with CCS and high-risk cardiovascular feature (i.e. ≥2 vascular beds, heart failure, renal insufficiency, peripheral artery disease, previous stroke or diabetes) and should be considered in these populations.

Ankle-brachial index in HIV infection.

Prognosis for patients with the human immunodeficiency virus (HIV) has improved with the introduction of highly active antiretroviral therapy (HAART). Evidence over recent years suggests that the incidence of cardiovascular disease is increasing in HIV patients. The ankle-brachial index (ABI) is a cheap and easy test that has been validated in the general population. Abnormal ABI values are associated with increased cardiovascular mortality. To date, six series of ABI values in persons with HIV have been published, but none was a prospective study. No agreement exists concerning the risk factors for an abnormal ABI, though its prevalence is clearly higher in these patients than in the general population. Whether this higher prevalence of an abnormal ABI is associated with a higher incidence of vascular events remains to be determined.

Pre-hospital antibiotic treatment and mortality caused by invasive meningococcal disease, adjusting for indication bias.

BACKGROUND: Mortality from invasive meningococcal disease (IMD) has remained stable over the last thirty years and it is unclear whether pre-hospital antibiotherapy actually produces a decrease in this mortality. Our aim was to examine whether pre-hospital oral antibiotherapy reduces mortality from IMD, adjusting for indication bias. METHODS: A retrospective analysis was made of clinical reports of all patients (n = 848) diagnosed with IMD from 1995 to 2000 in Andalusia and the Canary Islands, Spain, and of the relationship between the use of pre-hospital oral antibiotherapy and mortality. Indication bias was controlled for by the propensity score technique, and a multivariate analysis was performed to determine the probability of each patient receiving antibiotics, according to the symptoms identified before admission. Data on in-hospital death, use of antibiotics and demographic variables were collected. A logistic regression analysis was then carried out, using death as the dependent variable, and pre-hospital antibiotic use, age, time from onset of symptoms to parenteral antibiotics and the propensity score as independent variables. RESULTS: Data were recorded on 848 patients, 49 (5.72%) of whom died. Of the total number of patients, 226 had received oral antibiotics before admission, mainly betalactams during the previous 48 hours. After adjusting the association between the use of antibiotics and death for age, time between onset of symptoms and in-hospital antibiotic treatment, pre-hospital oral antibiotherapy remained a significant protective factor (Odds Ratio for death 0.37, 95% confidence interval 0.15-0.93). CONCLUSION: Pre-hospital oral antibiotherapy appears to reduce IMD mortality.

Efficacy and safety of the switch of Triumeq® to generic (abacavir + lamivudine) + Tivicay®: data at 48 weeks.

Introduction: Generic drugs are helpful to enhance the efficiency of the sanitary system. A generic coformulation of abacavir (ABC) and lamivudine (3TC) is available since 2016 in Spain. A report of our experience with its use is exposed. Methods: Patients between February 2017 and June 2017 who were taking Triumeq® were switched to the generic ABC + 3TC plus DTG. Efficacy, safety, reasons for discontinuation and costs savings were evaluated at 48 weeks. Results: Switch was made in 93 patients, with a median age of 47 years and a mean time of 12.33 years with HIV infection. Six patients (6.5%) discontinued the new ART, being toxicity of the central nervous system the most frequent reason. The effective saving derived from the change after 1 year of treatment was 151.127 €. Conclusions: The change from Triumeq® to a generic regimen of ABC + 3TC and another pill of DTG seems to be safe and efficient at 48 weeks.

Experience of Using an App in HIV Patients Older Than 60 Years: Pilot Program.

BACKGROUND: New technologies can promote knowledge of HIV infection among patients suffering from this disease. Older patients with HIV infection represent an increasingly large group that could benefit from the use of specific apps. OBJECTIVE: The aim of the study was to observe the acceptability and use of a mobile app on HIV infection in patients at least 60 years old and offer them the possibility of anonymously establishing contact with their peers. METHODS: A series of clinical and psychosocial parameters were studied in 30 HIV-infected patients of over 60 years. The patients must be at least 60 years old, with a follow-up in the outpatient clinic for at least 1 year and without pathologies that limit his or her life expectancy to less than a year. They must know how to read and write. To be part of the group assigned to the app, they had to have their own smartphone and confirm that they were connected to the internet from that device. Overall, 15 of them were randomized to use an app and 15 were in the control group. All tests were repeated after 6 months. RESULTS: The median age of patients was 66.5 years. Among them, 29 patients had an undetectable viral load at baseline. The median number of comorbid diseases was 2. Overall, 11 of them lived with their partners and 19 lived alone. They spent an average of 5 hours a day sitting down, and 56% (17/30) of them referred high physical activity. They scored 4 out of 5 for general quality of life perception. Moreover, 80% (24/30) presented high adherence to their treatment, and the average number of concomitant medications was 5. In the 6-min walking test, they covered a distance of 400 meters, and 3 of them desaturated during the test. The 15 patients made frequent use of the app, with 2407 sessions and an average of 7 min and 56 seconds time of use with a total of 13,143 screen views. During the 6 months of the trial, 3 non-AIDS events took place. There were no significant modifications to body mass index, blood pressure measurements, lipid profile, or immuno-virology information data. There were no differences in the questionnaire scores for perception of quality of life, confessed physical activity, or antiretroviral treatment (ART) and non-ART treatment adherence. CONCLUSIONS: Significant differences between studied parameters were not objectified in these patients, possibly because this trial has significant limitations, such as a small sample size and only a brief follow-up period. However, patients did use the app frequently, making this a possible intervention to be proposed in future subsequent studies.
