Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population

Prescription appropriateness of anti-diabetes drugs in elderly patients hospitalized in a clinical setting: evidence from the REPOSI Register

Diabetes is an increasing global health burden with the highest prevalence (24.0%) observed in elderly people. Older diabetic adults have a greater risk of hospitalization and several geriatric syndromes than older nondiabetic adults. For these conditions, special care is required in prescribing therapies including anti- diabetes drugs. Aim of this study was to evaluate the appropriateness and the adherence to safety recommendations in the prescriptions of glucose-lowering drugs in hospitalized elderly patients with diabetes. Data for this cross-sectional study were obtained from the REgistro POliterapie-Società Italiana Medicina Interna (REPOSI) that collected clinical information on patients aged ≥ 65 years acutely admitted to Italian internal medicine and geriatric non-intensive care units (ICU) from 2010 up to 2019. Prescription appropriateness was assessed according to the 2019 AGS Beers Criteria and anti-diabetes drug data sheets.Among 5349 patients, 1624 (30.3%) had diagnosis of type 2 diabetes. At admission, 37.7% of diabetic patients received treatment with metformin, 37.3% insulin therapy, 16.4% sulfonylureas, and 11.4% glinides. Surprisingly, only 3.1% of diabetic patients were treated with new classes of anti- diabetes drugs. According to prescription criteria, at admission 15.4% of patients treated with metformin and 2.6% with sulfonylureas received inappropriately these treatments. At discharge, the inappropriateness of metformin therapy decreased (10.2%, P < 0.0001). According to Beers criteria, the inappropriate prescriptions of sulfonylureas raised to 29% both at admission and at discharge. This study shows a poor adherence to current guidelines on diabetes management in hospitalized elderly people with a high prevalence of inappropriate use of sulfonylureas according to the Beers criteria

Beta-Blocker Use in Older Hospitalized Patients Affected by Heart Failure and Chronic Obstructive Pulmonary Disease: An Italian Survey From the REPOSI Register

Beta (β)-blockers (BB) are useful in reducing morbidity and mortality in patients with heart failure (HF) and concomitant chronic obstructive pulmonary disease (COPD). Nevertheless, the use of BBs could induce bronchoconstriction due to β2-blockade. For this reason, both the ESC and GOLD guidelines strongly suggest the use of selective β1-BB in patients with HF and COPD. However, low adherence to guidelines was observed in multiple clinical settings. The aim of the study was to investigate the BBs use in older patients affected by HF and COPD, recorded in the REPOSI register. Of 942 patients affected by HF, 47.1% were treated with BBs. The use of BBs was significantly lower in patients with HF and COPD than in patients affected by HF alone, both at admission and at discharge (admission, 36.9% vs. 51.3%; discharge, 38.0% vs. 51.7%). In addition, no further BB users were found at discharge. The probability to being treated with a BB was significantly lower in patients with HF also affected by COPD (adj. OR, 95% CI: 0.50, 0.37-0.67), while the diagnosis of COPD was not associated with the choice of selective β1-BB (adj. OR, 95% CI: 1.33, 0.76-2.34). Despite clear recommendations by clinical guidelines, a significant underuse of BBs was also observed after hospital discharge. In COPD affected patients, physicians unreasonably reject BBs use, rather than choosing a β1-BB. The expected improvement of the BB prescriptions after hospitalization was not observed. A multidisciplinary approach among hospital physicians, general practitioners, and pharmacologists should be carried out for better drug management and adherence to guideline recommendations

Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year.

Coffee reduces liver damage in a rat model of steatohepatitis: the underlying mechanisms and the role of polyphenols and melanoidins

Epidemiological data associate coffee consumption with a lower prevalence of chronic liver disease and a reduced risk of elevated liver enzyme levels (gamma glutamyl transpeptidase and alanine aminotransferase), advanced liver disease and its complications, and hepatocellular carcinoma. Knowledge of the mechanisms underlying these effects and the coffee components responsible for these properties is still lacking. In this study, 1.5 mL/day of decaffeinated coffee or its polyphenols or melanoidins (corresponding to approximately 2 cups of filtered coffee or 6 cups of espresso coffee for a 70-kg person) were added for 8 weeks to the drinking water of rats who were being fed a high-fat, high-calorie solid diet (HFD) for the previous 4 weeks. At week 12, HFD + water rats showed a clinical picture typical of advanced nonalcoholic steatohepatitis compared with control rats (normal diet + water). In comparison, HFD + coffee rats showed: (1) reduced hepatic fat and collagen, as well as reduced serum alanine aminotransferase and triglycerides; (2) a two-fold reduced/oxidized glutathione ratio in both serum and liver; (3) reduced serum malondialdehyde (lipid peroxidation) and increased ferric reducing antioxidant power (reducing activity); (4) reduced expression of tumor necrosis factor alpha (TNF-alpha), tissue transglutaminase, and transforming growth factor beta and increased expression of adiponectin receptor and peroxisome proliferator-activated receptor alpha in liver tissue; and (5) reduced hepatic concentrations of proinflammatory TNF-alpha and interferon-gamma and increased anti-inflammatory interleukin-4 and interleukin-10. Conclusion: Our data demonstrate that coffee consumption protects the liver from damage caused by a high-fat diet. This effect was mediated by a reduction in hepatic fat accumulation (through increased fatty acid beta-oxidation); systemic and liver oxidative stress (through the glutathione system); liver inflammation (through modulation of genes); and expression and concentrations of proteins and cytokines related to inflammation

Coffee reduces liver damage in a rat model of steatohepatitis: The underlying mechanisms and the role of polyphenols and melanoidins

Epidemiological data associate coffee consumption with a lower prevalence of chronic liver disease and a reduced risk of elevated liver enzyme levels (γ glutamyl transpeptidase and alanine aminotransferase), advanced liver disease and its complications, and hepatocellular carcinoma. Knowledge of the mechanisms underlying these effects and the coffee components responsible for these properties is still lacking. In this study, 1.5 mL/day of decaffeinated coffee or its polyphenols or melanoidins (corresponding to approximately 2 cups of filtered coffee or 6 cups of espresso coffee for a 70-kg person) were added for 8 weeks to the drinking water of rats who were being fed a high-fat, high-calorie solid diet (HFD) for the previous 4 weeks.

Garlic extract prevents CCl4-induced liver fibrosis in rats: The role of tissue transglutaminase

Background and aim: Tissue transglutaminase contributes to liver damage in the development of hepatic fibrosis. In a model of neurodegeneration, the therapeutic benefit of cystamine has been partly attributed to its inhibition of transglutaminase activity. Garlic extract contains many compounds structurally related to cystamine. We investigated the anti-fibrotic effect of garlic extract and cystamine as specific tissue transglutaminase inhibitors. Methods: Rat liver fibrosis was induced by intraperitoneal injection of carbon tetrachloride (CCl4) for 7 weeks. Cystamine or garlic extract was administrated by daily intraperitoneal injection, starting from the day after the first administration of CCl4. Hepatic function, histology, tissue transglutaminase immunostaining and image analysis to quantify Red Sirius stained collagen deposition were examined. Reverse transcription-polymerase chain reaction to detect alpha-SMA, IL-1β and tissue transglutaminase expression and Western blot for tissue transglutaminase protein amount were performed. Transglutaminase activity was assayed on liver homogenates by a radio-enzymatic method. Results: Transglutaminase activity was increased in CCl4 group and reduced by cystamine and garlic extract (p<0.05). Treatment with cystamine and garlic extract reduced the liver fibrosis and collagen deposition, particularly in the garlic extract group (p<0.01). Moreover, the liver damage improved and serum alanine aminotransferase was decreased (p<0.05). Tissue transglutaminase immunolocalised with collagen fibres and is mainly found in the ECM of damaged liver. Alpha-SMA, IL-1β, tissue transglutaminase mRNA and tissue transglutaminase protein were down-regulated in the cystamine and garlic extract groups compared to controls. Conclusion: These findings concurrently suggest that transglutaminase may play a pivotal role in the pathogenesis of liver fibrosis and may identify garlic cystamine-like molecules as a potential therapeutic strategy in the treatment of liver injury

Interferon-free regimens improve kidney function in patients with chronic hepatitis C infection

Background and aim: The impact of directly acting antiviral agent (DAA) regimens on renal function is not well defined and quite controversial. We evaluated the effect of DAAs on kidney function and the factors associated with an improvement or worsening. Patients and methods: The changes in estimated glomerular filtration rate (eGFR) in a cohort of 403 patients treated with a DAA regimen were evaluated. Results: The overall sustained virological response (SVR12) rate was 98%. The median eGFR progressively increased throughout treatment from 84.54 ml/min/1.73 m2 (IQR 70.8-97.3) to 88.12 ml/min/1.73 m2. Conversely, rates of patients with a eGFR more than 60 ml/min/1.73 m2 progressively increased from 83.1% at baseline to 87.8% at 12 weeks post-treatment (p < 0.05). Considering the change in eGFR according to the different factors, a significant improvement in eGFR was observed in the patients without diabetes (p < 0.001), in those with cirrhosis (p < 0.05), in those receiving a Sof-based regimen (p < 0.01) or not receiving RBV (p < 0.05), in those with a baseline eGFR less than 60 ml/min/1.73 m2 (p < 0.001) and in those with SVR (p < 0.05). An improvement in eGFR (defined as an increase in baseline eGFR of at least 10 ml/min/1.73 m2) was observed in 148 patients (36.7%). At multivariate analysis, age (aHR 0.96; 95 CI 0.93-0.99, p < 0.01) and a diagnosis of diabetes (aHR 0.02; 95 CI 0.20-0.87, p < 0.05) were inversely and independently associated with improvement in renal function, while the presence of Child-Pugh B cirrhosis at baseline was associated with an improvement in renal function (aHR 3.07; 95 CI 1.49-6.30, p < 0.01). Conclusions: DAAs correlate with an improvement in renal function, underlining the importance of hepatitis C virus eradication to achieve also an improvement in extra-hepatic disorders

Efficacy of the "first wave" Direct Acting antivirals against HCV infection: results from the Italian LINA (Liver Network Activity) cohort

Approximately 71 million people are chronically infected with HCV worldwide. Recently, interferonfree therapies effective against HCV became available and nowadays, therapeutic strategies include a combination of two or three drugs with different mechanisms of action. In the present study, we reported real-life SVR rates in a large cohort of four prescribing centers in a high-endemic area of Southern Italy. We conducted a prospective multicenter study among all the patients with chronic HCV infection, who received therapy with the first available interferon-free therapies between March 2015 and December 2017 and who referred to one of the 4 DAA-prescribing centers in Campania, Southern Italy. Patients with Child C cirrhosis, a diagnosis of active HCC at the baseline or who refused the consent form, were excluded. Nine-hundred fifty-three patients were enrolled. Most of the enrolled patients had HCV genotype 1b infection (66.4%), were older than 65 years (64.1%) and had advanced liver fibrosis (Metavir &gt; F4) (73.5%). The overall SVR12 rate was 98.5%. Patients with clinical cirrhosis had a similar SVR12 rate compared with those without cirrhosis (97.8% vs 99.2%, p=0.09), while patients with decompensated cirrhosis had a significantly lower rate of SVR12 compared with those without decompensated disease (95.3% vs 99.0%, p&lt;0.05). Patients aged more than 65 years had a similar rate of SVR12 compared with patients aged ≤ 65 years (98.6% vs 98.0%, p=0.57). Among patients &gt;65 years, those with clinical cirrhosis, as well as those with advanced liver fibrosis, had a similar SVR12 rate compared with the patients with a Metavir score &lt; F4 (98.3% vs 99.0%, p=0.70 and 98.6% vs 98.6%, p=1.00, respectively). In the present, real-life study, DAA regimens are effective and safe in patients with chronic HCV infection, regardless of age and stage of liver disease, providing very high rates of SVR12 (98.5%)
