Effectiveness and safety of intravenous tocilizumab to treat COVID-19-associated hyperinflammatory syndrome: Covizumab-6 observational cohort.

Although the starting event in COVID-19 is a viral infection some patients present with an over-exuberant inflammatory response, leading to acute lung injury (ALI) and adult respiratory distress syndrome (ARDS). Since IL-6 plays a critical role in the inflammatory response, we assessed the efficacy and safety of tocilizumab (TCZ) in this single-centre, observational study in all Covid-19 in-patient with a proven SARS-CoV-2 rapidly progressing infection to prevent ALI and ARDS. 104 patients with COVID-19 treated with TCZ had a lower mortality rate (5·8%) compared with the regional mortality rate (11%), hospitalized patient's mortality (10%), and slightly lower than hospitalized patients treated with our standard of care alone (6%). We found that TCZ rapidly decreased acute phase reactants, ferritin and liver release of proteins. D-Dimer decreased slowly. We did not observe specific safety concerns. Early administration of IL6-R antagonists in COVID-19 patients with impending hyperinflammatory response, may be safe and effective treatment to prevent, ICU admission and further complications.

Krebs von den Lungen-6 glycoprotein circulating levels are not useful as prognostic marker in COVID-19 pneumonia: A large prospective cohort study.

Coronavirus disease 2019 (COVID-19) has rapidly expanded worldwide. Currently, there are no biomarkers to predict respiratory worsening in patients with mild to moderate COVID-19 pneumonia. Small studies explored the use of Krebs von de Lungen-6 circulating serum levels (sKL-6) as a prognostic biomarker of the worsening of COVID-19 pneumonia. We aimed at a large study to determine the prognostic value of sKL-6 in predicting evolving trends in COVID-19. We prospectively analyzed the characteristics of 836 patients with COVID-19 with mild lung disease on admission. sKL-6 was obtained in all patients at least at baseline and compared among patients with or without respiratory worsening. The receiver operating characteristic curve was used to find the optimal cutoff level. A total of 159 (19%) patients developed respiratory worsening during hospitalization. Baseline sKL-6 levels were not higher in patients who had respiratory worsening (median {IQR} 315.5 {209-469} vs. 306 {214-423} U/ml p = 0.38). The last sKL-6 and the change between baseline and last sKL-6 were higher in the respiratory worsening group (p = 0.02 and p < 0.0001, respectively). The best sKL-6 cutoff point for respiratory worsening was 497 U/ml (area under the curve 0.52; 23% sensitivity and 85% specificity). sKL-6 was not found to be an independent predictor of respiratory worsening. A conditional inference tree (CTREE) was not useful to discriminate patients at risk of worsening. We found that sKL-6 had a low sensibility to predict respiratory worsening in patients with mild-moderate COVID-19 pneumonia and may not be of use to assess the risk of present respiratory worsening in inpatients with COVID-19 pneumonia.

Drug related problems in clinical practice: a cross-sectional study on their prevalence, risk factors and associated pharmaceutical interventions.

Drug-related problems (DRP) cause preventable negative health outcomes, especially during hospital admissions. The aim of our study was to examine the prevalence and characteristics of DRP in regular clinical pharmacy, as well as to determine those factors associated with a higher risk of DRP in the hospital setting. We analyzed data from a standardized registry database of regular pharmacy practice (2015- 2016). DRP were classified according to the Pharmaceutical Care Network Europe v6.2 classification. Cross-sectional data were obtained from 1602 adults admitted to medical wards. Crude and adjusted binary logistic regressions were performed to identify associations between potential risk factors and DRP. Overall DRP prevalence was high across medical specialties (45,1%), in a population characterized by advanced age, polypharmacy and multimorbidity. Problems leading to DRP were mainly classified into two domains (effectiveness and adverse reactions), being drug and dose selection the most frequent causes. Interventions were accepted and DRP were totally or partially solved in 74.1% and 4.81% of cases, respectively. In the adjusted model polypharmacy, allergies, BMI > 25 kg/m2 and clearance < 30 mL/min were associated with a higher risk of DRP. The participation of clinical pharmacists into multidisciplinary teams promotes the detection and solution of DRP. Polypharmacy, obesity, renal impairment and allergy are associated with a higher risk of DRP during admission.

Sarilumab (IL-6R antagonist) in critically ill patients with cytokine release syndrome by SARS-CoV2.

ABSTRACT: Blocking IL-6 pathways with sarilumab, a fully human anti-IL-6R antagonist may potentially curb the inflammatory storm of SARS-CoV2. In the present emergency scenario, we used "off-label" sarilumab in 5 elderly patients in life-threatening condition not candidates to further active measures. We suggest that sarilumab can modulate severe COVID-19-associated Cytokine Release Syndrome.

Causes of failure to achieve the low density lipoprotein cholesterol therapeutic target in patients with high and very high vascular risk controlled in Lipid and Vascular Risk Units. EROMOT study. / Causas de no consecución del objetivo terapéutico del colesterol de las lipoproteínas de baja densidad en pacientes de alto y muy alto riesgo vascular controlados en Unidades de Lípidos y Riesgo Vascular. Estudio EROMOT.

OBJECTIVES: Determination of the level of achievement of the low density lipoprotein cholesterol (LDL-C) therapeutic target in patients with high and very high vascular risk treated in Lipid Units, as well as the causes of non-achievement. PATIENTS AND METHOD: Multicentre retrospective observational study that included patients over 18 years with high and very high vascular risk, according to the criteria of the 2012 European Guidelines on Cardiovascular Disease Prevention, referred consecutively to Lipid Units between January and June 2012 and with follow-up two years after the first visit. RESULTS: The study included a total of 243 patients from 16 lipid units. The mean age was 52.2 years (SD 13.7), of whom 62.6% were males, and 40.3% of them were very high risk. At the first visit, 86.8% (25.1% in combination) and 95.0% (47.3% in combination) in the second visit (P<.001) were treated with lipid-lowering treatment. The therapeutic target was achieved by 28% (95 CI: 22.4-34.1). As regards the causes of non-achievement, 24.6% were related to the medication (10.3% maximum tolerated dose and 10.9% due to the appearance of adverse effects), 43.4% due to the physician (19.4% by inertia, 13.7% considering that target already reached), and 46.9% due to the patient, highlighting the therapeutic non-compliance (31,4%). CONCLUSIONS: LDL-C targets were achieved in about one-third of patients. The low adherence of the patient, followed by medical inertia are the most frequent causes that can explain these results.

[Differences in the reduction of blood pressure according to drug administration at activity hours or rest hours]. / Diferencias en la reducción de la presión arterial en función de la toma de la medicación en horario diurno o nocturno.

BACKGROUND AND OBJECTIVE: In this study, 123 recordings of blood pressure (BP) obtained by ambulatory BP monitoring were analyzed. These recordings were measured in 2011 in patients from a Spanish tertiary university hospital. All participating patients were treated with 2, 3 or 4 anti-hypertensive drugs. The main aim of this study was to determine differences in BP control, if any, depending on the medication schedule. Thus, BP levels were studied at 3 periods of the day: activity hours, rest hours and 24h. PATIENTS AND METHOD: We compared subjects taking all anti-hypertensive agents during the day (n=70, group 1) with those taking at least one at night (n=53, group 2). RESULTS: Significant differences were found on diastolic BP, where group 2 patients had lower levels at activity, 24h periods and sleep-time. Even if it was not statistically significant, lower levels of systolic BP from group 2 were also observed at activity and 24h periods as well as lower levels of systolic, diastolic and mean BP at rest hours periods. There were also significant group differences in relation to the number of prescribed agents (with the mean being higher for group 2) and the type of agent (beta-blockers and calcium antagonists were more prevalent in group 2). Nevertheless, the multivariate regression analysis done taking into account these variables did not change the observed statistical significance. CONCLUSION: The administration of anti-hypertensive drugs at night could be associated with lower BP levels.

[Atherosclerosis and anti-oxidized low density lipoprotein antibodies in an elderly population]. / Aterosclerosis y anticuerpos anti-OxLDL en una población geriátrica.

BACKGROUND: Antibodies to oxidized LDL (anti-OxLDL) have been found to be associated with atherosclerosis. The aim of the study was to evaluate the relationship between anti-OxLDL antibodies and atherosclerosis in the elderly. PATIENTS AND METHOD: We studied several risk factors and different clinical manifestations of atherosclerosis in 100 people older than 65 years and in 48 healthy blood donor controls (age range: 20 to 55 years). Anti-OxLDL antibodies were measured by ELISA. RESULTS: Thirty-one percent of the patients tested positive for anti-OxLDL. This percentage increased in the group of subjects without any risk factor or clinical manifestation (66.6%) as it was the case of the mean optical density (O.D.) value (O.D. = 0.671 vs. 0.357 in our general geriatric population). Most of those with a proven atherosclerotic event tested negative for anti-OxLDL antibodies and a statistically significant difference was shown for those with a calcified aortic arch (P = 0.041, 95% CI 0.15-0.97). Mean value of risk factors and clinical manifestations was 3.50 among anti-OxLDL-negative patients, whereas it was 2.51 in the anti-OxLDL-positive group (P = 0.035, 95% CI 0.07-1.91). Actually, when more adverse effects were present, patients' trend to test negative for anti-OxLDL antibodies was higher. An inverse correlation was observed between anti-OxLDL titers and the relative risk of coronary heart disease (P = 0.020). CONCLUSIONS: The cause of the decrease of free anti-OxLDL antibodies in situations that lead to an oxidative stress is unknown but it may be explained by the formation of immunocomplexes in an effort to ease the clearance of oxidized substrates.
