Dynamic profiles and predictive values of some biochemical and haematological quantities in COVID-19 inpatients.

INTRODUCTION: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in some hospitalized patients has shown some important alterations in laboratory tests. The aim of this study was to establish the most relevant quantities associated with the worst prognosis related to COVID-19. MATERIALS AND METHODS: This was a descriptive, longitudinal, observational and retrospective study, in a cohort of 845 adult inpatients from Bellvitge University Hospital (L'Hospitalet de Llobregat, Barcelona, Spain). A multivariate regression analysis was carried out in demographic, clinical and laboratory data, comparing survivors (SURV) and non-survivors (no-SURV). A receiver operating characteristic analysis was also carried out to establish the cut-off point for poor prognostic with better specificity and sensibility. Dynamic changes in clinical laboratory measurements were tracked from day 1 to day 28 after the onset of symptoms. RESULTS: During their hospital stay, 18% of the patients died. Age, kidney disease, creatinine (CREA), lactate-dehydrogenase (LD), C-reactive-protein (CRP) and lymphocyte (LYM) concentration showed the strongest independent associations with the risk of death in the multivariate regression analysis. Established cut-off values for poor prognosis for CREA, LD, CRP and LYM concentrations were 75.0 µmol /L, 320 U/L, 80.9 mg/L and 0.69 x109/L. Dynamic profile of laboratory findings, were in agreement with the consequences of organ damage and tissue destruction. CONCLUSIONS: Age, kidney disease, CREA, LD, CRP and LYM concentrations in COVID-19 patients from the southern region of Catalonia provide important information for their prognosis. Measurement of LD has demonstrated to be very good indicator of poor prognosis at initial evaluation because of its stability over time.

Genetic contribution to lipid target achievement with statin therapy: a prospective study.

Statin therapy response is highly variable. Variants of lipid metabolism genes and statin pharmacokinetic modulators could play a role, however, the impact of most of these variants remains unconfirmed. A prospective and multicenter study included 252 patients was carried out in order to assess, according to achievement of LDL-C or non-HDL-C therapeutic targets and quantitative changes in lipid profiles, the impact of CETP, ABCA1, CYP2D6, and CYP2C9 gene candidate variants on the simvastatin, atorvastatin, and rosuvastatin response. Patients carrier ABCA1 rs2230806 and CYP2D6*3 variants are less likely to achieve therapeutic lipid targets (p = 0.020, OR = 0.59 [0.37, 0.93]; p = 0.040, OR = 0.23 [0.05, 0.93], respectively). Among CETP variants, rs708272 was linked to a 10.56% smaller reduction in LDL-C with rosuvastatin (95% CI = [1.27, 19.86] %; p = 0.028). In contrast, carriers of rs5882 had a 13.33% greater reduction in LDL-C (95% CI = [25.38, 1.28]; p = 0.032). If these findings are confirmed, ABCA1, CYP2D6, and CETP genotyping could be used to help predict which statin and dosage is appropriate in order to improve personalized medicine.

KIF6 gene as a pharmacogenetic marker for lipid-lowering effect in statin treatment.

INTRODUCTION: The therapeutic response to statins has a high interindividual variability with respect to reductions in plasma LDL-cholesterol (c-LDL) and increases in HDL cholesterol (c-HDL). Many studies suggest that there is a relationship between the rs20455 KIF6 gene variant (c.2155T> C, Trp719Arg) and a lower risk of cardiovascular disease in patients being treated with statins. AIM: The aim of this study was to investigate whether or not the c.2155T> C KIF6 gene variant modulates the hypercholesteremic effects of treatment with simvastatin, atorvastatin, or rosuvastatin. MATERIALS AND METHODS: This was a prospective, observational and multicenter study. Three hundred and forty-four patients who had not undergone prior lipid-lowering treatment were recruited. Simvastatin, atorvastatin or rosuvastatin were administered. Lipid profiles and multiple clinical and biochemical variables were assessed before and after treatment. RESULTS: The c.2155T> C variant of the KIF6 gene was shown to influence physiological responses to treatment with simvastatin and atorvastatin. Patients who were homozygous for the c.2155T> C variant (CC genotype, ArgArg) had a 7.0% smaller reduction of LDL cholesterol levels (p = 0.015) in response to hypolipidemic treatment compared to patients with the TT (TrpTrp) or CT (TrpArg) genotype. After pharmacological treatment with rosuvastatin, patients carrying the genetic variant had an increase in c-HDL that was 21.9% lower compared to patients who did not carry the variant (p = 0.008). CONCLUSION: Being a carrier of the c.2155T> C variant of the KIF6 gene negatively impacts patient responses to simvastatin, atorvastatin or rosuvastatin in terms of lipid lowering effect. Increasing the intensity of hypolipidemic therapy may be advisable for patients who are positive for the c.2155T> C variant.

Tasa de filtrado glomerular estimada, eventos cardiovasculares y mortalidad por grupos de edad en individuos de 60 o más años del sur de Europa / Estimated glomerular filtration rate, cardiovascular events and mortality across age groups among individuals older than 60 years in Southern Europe

Introducción y objetivos: Los individuos con tasa de filtrado glomerular estimada (TFGe) disminuida tienen mayor riesgo de muerte por todas las causas (MT) y cardiovascular; se debate si los sujetos mayores con TFGe entre 45 y 59 ml/min/1,73 m2 también tienen un riesgo aumentado. Se evaluó la asociación entre la TFGe y la MT y los eventos cardiovasculares (ECV) en individuos de edad 60-74 y ≥ 75 años en un área de baja incidencia de enfermedad coronaria. Métodos: Se realizó un estudio retrospectivo de cohortes utilizando registros electrónicos de atención primaria y hospital. Se incluyó a 130.233 individuos de 60 o más años con una determinación de creatinina entre el 1 de enero de 2010 y el 31 de diciembre de 2011 y una TFGe según la fórmula de la Chronic Kidney Disease Epidemiology Collaboration. Las asociaciones independientes entre la TFGe y la MT y el ingreso por ECV se evaluaron mediante modelos de regresión de Cox y Fine-Gray respectivamente. Resultados: Media de edad, 70 años; el 56,1% eran mujeres. El 13,5% tenía una TFGe < 60 (el 69,7%, TFGe 45-59). Durante una mediana de seguimiento de 38,2 meses, 6.474 participantes fallecieron y 3.746 presentaron ECV. Tanto para la MT como para los ECV, las HR ajustadas de los participantes de 75 o más años fueron significativas con TFGe < 60. Con TFGe 45-59, para MT fueron HR = 1,61; IC95%, 1,37-1,89 y HR = 1,19; IC95%, 1,10-1,28 en los grupos de edad de 60-74 y ≥ 75 años respectivamente, y para ECV, HR = 1,28; IC95%, 1,08-1,51 y HR = 1,12; IC95%, 0,99-1,26. Conclusiones: En un área de baja incidencia de enfermedad coronaria, el riesgo de muerte y ECV fue de mayor a menor TFGe. A edades ≥ 75 años, la categoría de TFGe 45-59, en el límite significativo de ECV, incluyó a muchos individuos sin riesgo adicional significativo

Introduction and objectives: Individuals with a decreased estimated glomerular filtration rate (eGFR) are at increased risk of all-cause (ACM) and cardiovascular mortality; there is ongoing debate about whether older individuals with eGFR 45 to 59 mL/min/1.73 m2 are also at increased risk. We evaluated the association between eGFR and ACM and cardiovascular events (CVE) in people aged 60 to 74 and ≥ 75 years in a population with a low coronary disease incidence. Methods: We conducted a retrospective cohort study by using primary care and hospital electronic records. We included 130 233 individuals aged ≥ 60 years with creatinine measurement between January 1, 2010 and December 31, 2011; eGFR was estimated by using the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. The independent association between eGFR and the risk of ACM and hospital admission due to CVE were determined with Cox and Fine-Gray regressions, respectively. Results: The median was age 70 years, and 56.1% were women; 13.5% had eGFR < 60 (69.7% eGFR 45-59). During a median follow-up of 38.2 months, 6474 participants died and 3746 had a CVE. For ACM and CVE, the HR in older individuals became significant at eGFR < 60. Fully adjusted HR for ACM in the eGFR 45 to 59 category were 1.61; 95%CI, 1.37-1.89 and 1.19; 95%CI, 1.10-1.28 in 60- to 74-year-olds and ≥ 75-year-olds, respectively; for CVE HR were 1.28; 95%CI, 1.08-1.51 and 1.12; 95%CI, 0.99-1.26. Conclusions: In a region with low coronary disease incidence, the risk of death and CVE increased with decreasing eGFR. In ≥ 75-year-olds, the eGFR 45 to 59 category, which had borderline risk for CVE, included many individuals without significant additional risk

Estimation of glomerular filtration rate by MDRD-4 IDMS and CKD-EPI in individuals of 60 years of age or older in primary care.

OBJECTIVE: To compare the prevalence and classification of chronic kidney disease (CKD) in accordance with the estimated glomerular filtration rate (eGFR) by MDRD-4 IDMS and CKD-EPI in individuals ≥ 60 years of age in primary care. MATERIAL AND METHODS: Cross-sectional descriptive observational study. Subjects ≥ 60 years treated at 40 primary care centres with serum creatinine determination conducted between 1 January and 31 December 2010 at a single centralised laboratory. EXCLUSION CRITERIA: renal transplantation, home care. VARIABLES: socio-demographic, anthropometric, risk factors and cardiovascular disease as recorded in electronic medical records and serum creatinine concentration by a standardised compensated kinetic Jaffe method with IDMS and eGFR by MDRD-4 IDMS and CKD-EPI. Agreement was analysed using the kappa coefficient and the Bland-Altman graphical method. RESULTS: 97,554 individuals (57.3% women, mean age 70.0 [Q1: 65.0, Q3: 77.0]). Median eGFR with MDRD 78.7 [66.7, 91.0] ml/min/1.73m² (77.9 for women, 79.7 for men, P<.001) and 81.8 [68.5, 90.5] ml/min/1.73 m² (P=.311) with CKD-EPI, eFG(MDRD) prevalence <60 15.0% (16.5% women, 13.1% men and 6.5% in ≤ 70 years, 24%> 70 years) with CKD-EPI 14.2% (15.0% female, 13.0% male, 4.7% in ≤ 70 years, 24.1% in> 70 years) . There was an overall agreement of 85.6% (kappa coefficient = 0.75) in women> 70 years of 86.6% (kappa = 0.77), of 83.2% (kappa = 0.69) in men> 70 years, of 82.7% (kappa = 0.68) in women ≤ 70 years and 90% (kappa = 0.81) in men ≤ 70 years. CONCLUSIONS: CKD-EPI decreased the prevalence of CKD especially in women ≤ 70 years; the prevalence increased in men> 70 years. One in eight individuals with stage 3a was reclassified to no disease; reclassified individuals had lower comorbidity.
