RESUMO

AIMS: Bacterial translocation, defined as the presence of living bacteria or bacterial fragments in both mesenteric lymph nodes or systemic circulation, can cause a severe inflammatory reaction in patients with cirrhosis. This study aimed to compare lipid peroxidation associated with liver damage in different experimental models of bile duct ligation: proximal double ligation and transection versus proximal simple ligation versus sham. MATERIALS AND METHODS: Sixty-two male rats underwent one of three bile duct surgical interventions: proximal double ligation and transection (n = 22); proximal simple ligation (n = 19); or sham operation (n = 21). We performed microbiological culture of mesenteric lymph nodes; portal and cava blood, spleen and liver cultures; and histological analysis of liver parenchyma. Samples of blood and liver were obtained at laparotomy for malondialdehyde quantification. KEY FINDINGS: Serum malondialdehyde levels were significantly higher in simple ligature animals (3.7 nmol/mg, standard deviation [SD] 2.1) compared to controls (1.6 nmol/mg SD 0.5; p = 0.001) or double ligature (0.3 nmol/mg SD 0.3; p = 0.001). Liver malondialdehyde levels were significantly higher in animals subjected to double ligation vs controls (9.0 nmol/mg SD 2.8 vs. 1.7 nmol/mg SD 1.0; p = 0.0007) and simple ligature (2.9 nmol/mg SD 2.0; p = 0.0001). Overall incidence of bacterial translocation was similar in simple and double ligatures (22.2 % and 21 % respectively), and significantly higher than in controls. SIGNIFICANCE: the type of bile duct ligation influences the type and localization of lipid peroxidation, but does not influence the development of bacterial translocation.

RESUMO

AIM: This work aims to assess the effect of weekly subcutaneous semaglutide on biomarkers of metabolic-associated fatty liver disease (MAFLD), namely the hepatic steatosis index (HSI) and the fibrosis-4 (FIB-4) index, at 24 weeks in outpatients attended to in internal medicine departments. METHODS: This study analyzed patients in an ongoing, multicenter, prospective, pre-post, uncontrolled cohort registry that enrolls unique, consecutive patients with type 2 diabetes treated with weekly subcutaneous semaglutide. Steatosis/fibrosis were determined by HSI (<30 ruled out, >36 steatosis) and FIB-4 (<1.3 ruled out, >2.67 fibrosis), respectively. RESULTS: The sample included 213 patients (46.9% women) with a median age of 64 (19) years. The median baseline body mass index and weight were 36.1 (8.4) kg/m2 and 98 (26.9) kg, respectively. A total of 99.9% had HSI values indicating steatosis, with a mean HSI of 47.9 (8.2). Additionally, 10.8% had fibrosis (FIB-4 > 2.67) and 42.72% had values in intermediate ranges (FIB-4 1.3-2.67). At 24 weeks, there was a significant reduction in HSI (-2.36 (95%CI 1.83-2.9) p < 0.00001) and FIB-4 (-0.075 (95%CI 0.015-0.14) p < 0.016), mainly related to declines in body weight, triglyceride levels, insulin resistance (estimated by the triglyceride-glucose index), and liver enzymes. CONCLUSION: These results show that weekly subcutaneous semaglutide had a beneficial effect on liver steatosis that went beyond glucose control. Its effects were mainly related to weight loss, a decline in biomarkers, and improvements in insulin sensitivity. For many patients, early detection is essential for improving MAFLD outcomes and may allow for selecting the most efficient treatment options.

RESUMO

Background: Describe the profile of patients with obesity in internal medicine to determine the role of adiposity and related inflammation on the metabolic risk profile and, identify various "high-risk obesity" phenotypes by means of a cluster analysis. This study aimed to identify different profiles of patients with high-risk obesity based on a cluster analysis. Methods: Cross-sectional, multicenter project that included outpatients attended to in internal medicine. A total of 536 patients were studied. The mean age was 62 years, 51% were women. Patients were recruited from internal medicine departments over two weeks in November and December 2021 and classified into four risk groups according to body mass index (BMI) and waist circumference (WC). High-risk obesity was defined as BMI > 35 Kg/m2 or BMI 30−34.9 Kg/m2 and a high WC (>102 cm for men and >88 cm for women). Hierarchical and partitioning clustering approaches were performed to identify profiles. Results: A total of 462 (86%) subjects were classified into the high-risk obesity group. After excluding 19 patients missing critical data, two profiles emerged: cluster 1 (n = 396) and cluster 2 (n = 47). Compared to cluster 1, cluster 2 had a worse profile, characterized by older age (77 ± 16 vs. 61 ± 21 years, p < 0.01), a Charlson Comorbidity Index > 3 (53% vs. 5%, p < 0.001), depression (36% vs. 19%, p = 0.008), severe disability (64% vs. 3%, p < 0.001), and a sarcopenia score ≥ 4 (79% vs. 16%, p < 0.01). In addition, cluster 2 had greater inflammation than cluster 1 (hsCRP: 5.8 ± 4.1 vs. 2.1 ± 4.5 mg/dL, p = 0.008). Conclusions: Two profiles of subjects with high-risk obesity were identified. Based on that, older subjects with obesity require measures that target sarcopenia, disability, psychological health, and significant comorbidities to prevent further health deterioration. Longitudinal studies should be performed to identify potential risk factors of subjects who progress from cluster 1 to cluster 2.

RESUMO

OBJECTIVE: To describe the impact of different doses of corticosteroids on the evolution of patients with COVID-19 pneumonia, based on the potential benefit of the non-genomic mechanism of these drugs at higher doses. METHODS: Observational study using data collected from the SEMI-COVID-19 Registry. We evaluated the epidemiological, radiological and analytical scenario between patients treated with megadoses therapy of corticosteroids vs low-dose of corticosteroids and the development of complications. The primary endpoint was all-cause in-hospital mortality according to use of corticosteroids megadoses. RESULTS: Of a total of 14,921 patients, corticosteroids were used in 5,262 (35.3%). Of them, 2,216 (46%) specifically received megadoses. Age was a factor that differed between those who received megadoses therapy versus those who did not in a significant manner (69 years [IQR 59-79] vs 73 years [IQR 61-83]; p < .001). Radiological and analytical findings showed a higher use of megadoses therapy among patients with an interstitial infiltrate and elevated inflammatory markers associated with COVID-19. In the univariate study it appears that steroid use is associated with increased mortality (OR 2.07 95% CI 1.91-2.24 p < .001) and megadose use with increased survival (OR 0.84 95% CI 0.75-0.96, p 0.011), but when adjusting for possible confounding factors, it is observed that the use of megadoses is also associated with higher mortality (OR 1.54, 95% CI 1.32-1.80; p < .001). There is no difference between megadoses and low-dose (p .298). Although, there are differences in the use of megadoses versus low-dose in terms of complications, mainly infectious, with fewer pneumonias and sepsis in the megadoses group (OR 0.82 95% CI 0.71-0.95; p < .001 and OR 0.80 95% CI 0.65-0.97; p < .001) respectively. CONCLUSION: There is no difference in mortality with megadoses versus low-dose, but there is a lower incidence of infectious complications with glucocorticoid megadoses.

RESUMO

AIM: To assess the efficacy of sodium-glucose cotransporter-2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptors agonist (GLP-1RA) therapy on liver steatosis measured by fatty liver index (FLI) and hepatic steatosis index (HSI) at 26 weeks in outpatients with diabetes and obesity. METHODS: Observational, prospective, multicenter study. Patients with steatosis determined by FLI (values <30 rule out and >60 indicate steatosis) and HIS (values <30 rule out and >36 indicate steatosis) who received combination therapy were included. Patients were stratified into three groups according to the sequential order of treatment. We used robust statistical methods. RESULTS: In our final report we included 174 patients (58.6% males), mean age 61.9 (10) years. Baseline body mass index, waist circumference and weight were 36.5 (6.8) kg/m2, 117.5 (15.1) cm and 99.4 (20.5) kg, respectively. One hundred percent of patients had altered biomarkers of fatty liver scores (FLI 96 [13] and HSI 49.2 [8.5]). At 26 weeks, significant reductions in FLI (-4.5 [95% CI 3.5-5.9] p < .001) and HSI (-2.4 [95% CI 1.6-3.2] p < .001) were found in the total sample and pre-specified treatment and FLI cut-off point subgroups. CONCLUSION: Our results show a beneficial effect of the combination of GLP-1RAs plus SGLT2is on liver steatosis that goes beyond glucose control, and it is related mainly to weight loss, a decline in biomarkers and reductions in abdominal circumference. For many patients, early detection is essential to improving outcomes in NAFLD and could allow us to select the most efficient treatment options.

RESUMO

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.

RESUMO

INTRODUCTION: This study assessed the efficacy and safety of insulin glargine 300 U/mL (Gla-300) during hospitalization and therapy intensification at discharge in insufficiently controlled people with type 2 diabetes. RESEARCH DESIGN AND METHODS: COBALTA (for its acronym in Spanish, COntrol Basal durante la hospitalizacion y al ALTA) was a multicenter, open-label, single-arm, phase IV trial including 112 evaluable inpatients with type 2 diabetes insufficiently controlled (glycosylated hemoglobin (HbA1c) 8%-10%) with basal insulin and/or non-insulin antidiabetic drugs. Patients were treated with a basal-bolus-correction insulin regimen with Gla-300 during the hospitalization and with Gla-300 and/or non-insulin antidiabetics for 6 months after discharge. The primary endpoint was the HbA1c change from baseline to month 6 postdischarge. RESULTS: HbA1c levels decreased from 8.8%±0.6% at baseline to 7.2%±1.1% at month 6 postdischarge (p<0.001, mean change 1.6%±1.1%). All 7-point blood glucose levels decreased from baseline to 24 hours predischarge (p≤0.001, mean changes from 25.1±66.6 to 63.0±85.4 mg/dL). Fasting plasma glucose also decreased from baseline to 24 hours predischarge (p<0.001), month 3 (p<0.001) and month 6 (p<0.001) postdischarge (mean changes 51.5±90.9, 68.2±96.0 and 77.6±86.4 mg/dL, respectively). Satisfaction was high and hyperglycemia/hypoglycemia perception was low according to the Diabetes Treatment Satisfaction Questionnaire at month 6 postdischarge. The incidence of confirmed (glucose<70 mg/dL)/severe hypoglycemia was 25.0% during hospitalization and 59.1% 6 months after discharge. No safety concerns were reported. CONCLUSIONS: Inpatient and intensification therapy at discharge with Gla-300 improved significantly glycemic control of patients with type 2 diabetes insufficiently controlled with other basal insulin and/or non-insulin antidiabetic medication, with high treatment satisfaction. Gla-300 could therefore be a treatment choice for hospital and postdischarge diabetes management.

RESUMO

BACKGROUND: In the last 10 years enzyme replacement therapy (ERT) has become an alternative for the treatment of patients with Hunter disease (HD). Nevertheless, the information regarding efficacy and safety is scarce and mainly based on the pivotal trials. This scarcity is especially evident for adults and severe forms of HD. METHODS: A systematic review of publications in the electronic databases PUBMED, EMBASE and Cochrane Central was undertaken. Clinical trials and observational studies were included. The data about efficacy and security were retrieved and analysed with Review Manager version 5.3. RESULTS: 677 records were found, 559 remaining after the removal of duplicates. By title and abstract review, 427 were excluded. Full reading of the rest was made (122 publications) and 42 were finally included. It was not possible to perform meta-analysis of all the endpoints due to high heterogeneity in the reporting and measuring of variables in each publication. Eight clinical trials were included, 6 with high risk of bias. The quality of the other studies was low in 12%, average in 68% and good in 21%. Main findings were: a reduction in the elimination of glycosaminoglycans (GAG) in urine in all the studies (26/26), decrease in liver and spleen size (18/18), increase of 52.59 m (95% CI, 36, 42-68.76, p < .001) in the 6-min walk test (TM6M), increase in forced vital capacity (FVC) of 9.59% (95% CI 4.77-14.51, p < .001), reduction of the left ventricular mass index of 3.57% (95% CI 1.2-5.93) and reduction in mortality (OR) of 0.44 (0.27-0.71). DISCUSSION: The data suggests a clear and consistent effect of ERT in HD reducing the accumulation of GAGs in the body, demonstrated by the reduction of its urinary excretion, as well as by the reduction of its deposits (spleen, liver and heart). Likewise, there is an improvement in physical and respiratory function. In addition, a reduction in mortality has been observed. Lack of studies, small size of the samples, and methodological deficiencies are the main limitations to establish definite conclusions. CONCLUSIONS: The data suggests that ERT is effective and safe in the treatment of HD. There is a need to evaluate patient-centred outcomes and the impact on quality of life.

RESUMO

OBJECTIVES: Scientific literature about the combination of glucagon-like peptide-1 receptor agonists (GLP-1ra) and sodium-glucose cotransporter 2 (SGLT2) inhibitors in older patients is scarce. We sought to assess the real-world efficacy and safety of SGLT2 inhibitors and GLP-1ra combination therapy in older patients (>65 years of age). METHODS: This was an observational, prospective, multicenter study based on clinical practice. Patients were stratified according to tertiles of baseline glycated hemoglobin (A1C) levels and to treatment schedule. RESULTS: We included 113 patients (65.5% men, mean age 70.4±8.8 years). The body mass index was 36.5 (±6.6) kg/m2. The baseline A1C level was 8.0% (±1.2%). At the 6-month follow up, we found a significant reduction in A1C levels (-1.1%; p<0.0001), body mass index (-2.1 kg/m2; p<0.00003) and systolic blood pressure (-13 mmHg; p<0.000005). Patients who had the highest baseline A1C levels (≥8.4%) showed greater improvement in A1C levels (p<0.0001), weight (p<0.0001) and quality-of-life scores (p<0.0001). The greatest reduction in A1C levels and weight was seen in patients who started both drugs simultaneously (p<0.0001). The second greatest reduction was seen when GLP-1ra was added to previous treatment with an SGLT2i (p<0.0001). Also of note was a decrease in systolic blood pressure in patients for whom an SGLT2i was added to previous GLP-1ra treatment (p<0.0001). Of the patients, 34.3% achieved the combined endpoint of A1C levels <7% and weight loss ≥5% without hypoglycemia. CONCLUSIONS: This study's findings provide evidence of clinically meaningful reductions in A1C level, body weight and systolic blood pressure in older patients with type 2 diabetes who are taking combined regimens. The dropout and hypoglycemia rates were minimal, and treatment was tolerated well.
