Serum Cholesterol and Impact of Age on Coronary Heart Disease Death in More Than 4 Million Veterans. J Am Heart Assoc 2023; 12:e030496. [PMID: 37889207 PMCID: PMC10727410 DOI: 10.1161/jaha.123.030496] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 09/29/2023] [Indexed: 10/28/2023]
Abstract
Background The lipid hypothesis postulates that lower blood cholesterol is associated with reduced coronary heart disease (CHD) risk, which has been challenged by reports of a U-shaped relation between cholesterol and death in recent studies. We sought to examine whether the U-shaped relationship is true and to assess the impact of age on this association. Method and Results We conducted a prospective cohort study of 4 467 942 veterans aged >18 years, with baseline outpatient visits from 2002 to 2007 and follow-up to December 30, 2018, in the Veterans Health Administration electronic health record system. We observed a J-shaped relation between total cholesterol (TC) and CHD mortality after a comprehensive adjustment of confounding factors: flat for TC <180 mg/dL, and greater risk was present at higher cholesterol levels. Compared with veterans with TC between 180 and 199 mg/dL, the multiadjusted hazard ratios (HRs) for CHD death were 1.03 (95% CI, 1.02-1.04), 1.07 (95% CI, 1.06-1.09), 1.15 (95% CI, 1.13-1.18), 1.25 (95% CI, 1.22-1.28), and 1.45 (95% CI, 1.42-1.49) times greater among veterans with TC (mg/dL) of 200 to 219, 220 to 239, 140 to 259, 260 to 279 and ≥280, respectively. Similar J-shaped TC-CHD mortality patterns were observed among veterans with and without statin use at or before baseline. Conclusions The cholesterol paradox, for example, higher CHD death in patients with a low cholesterol level, was a reflection of reverse causality, especially among older participants. Our results support the lipid hypothesis that lower blood cholesterol is associated with reduced CHD. Furthermore, the hypothesis remained true when TC was low due to use of statins or other lipid-lowering medication.

Lipid Profile as a Predictive Marker for Organ Dysfunction after Thoracoabdominal Surgery: A Cross-sectional Study. IRANIAN JOURNAL OF MEDICAL SCIENCES 2023; 48:465-473. [PMID: 37786464 PMCID: PMC10541545 DOI: 10.30476/ijms.2022.95364.2672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 08/16/2022] [Accepted: 09/24/2022] [Indexed: 10/04/2023]
Abstract
Background Plasma total cholesterol is considered a negative acute phase reactant. In various pathological conditions, such as trauma, sepsis, burns, and liver dysfunction, as well as post-surgery, serum cholesterol level decreases. This study aimed to investigate the role of lipid profiles in determining the probability of organ dysfunction after surgery. Methods This cross-sectional study included patients who underwent thoracoabdominal surgery and were admitted to the intensive care unit of Imam Reza Hospital in Tabriz, Iran, between October 2016 and September 2018. During the first two days of admission, blood samples were taken, and serum levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and albumin were measured. The relation between the changes in these laboratory markers and six organ functions including cardiovascular, respiratory, renal, central nervous system, hepatic, and hematologic, length of stay in the hospital and intensive care unit, mechanical ventilation duration, and vasopressor use were investigated. The independent t test was used to compare continuous variables. The association between different variables and organ dysfunction and mortality was evaluated by using logistic regression. Results The serum TC increased the risk of mortality (OR=1.09, 95%CI=1.06-1.11, P<0.001), renal dysfunction (OR=1.09, 95%CI=1.06-1.12; P<0.001), liver dysfunction (OR=1.07, 95%CI=1.03-1.10; P<0.001), respiratory dysfunction (OR=1.08, 95%CI=1.05-1.13; P<0.001). Moreover, LDL, HDL, and TG were found to be inversely related to mortality, organ dysfunction, length of stay in the hospital and intensive care unit, mechanical ventilation duration, and vasopressor use. Conclusion TC could be considered a risk factor for mortality, organ dysfunction, and clinical outcomes. On the other hand, LDL, HDL, and TG played a protective role in the patients' mortality, organ dysfunction, and clinical outcomes.

Abstract
Introduction India accounts for one-fourth of the global tuberculosis (TB) burden and also faces a rising burden of non-communicable diseases. Only a few have studied the association between the infective pathogenesis of TB and cardiovascular diseases (CVD). Methods A cross-sectional exploratory analytical design was used to compare CVD risk factors and immunological and radiological parameters. This was a pilot study conducted in two primary health centers in urban Puducherry between February 2020 and March 2021. Household contacts (HHC) were either spouses or siblings of the newly diagnosed pulmonary tuberculosis (PTB) patients selected for comparison as their exposure to infection would be similar to those who were diseased yet did not develop illness. Assuming a difference of 5% in CVD risk between the general population and TB patients, with a 95% confidence interval, the sample size calculated was 153 in each group by nMaster v2.0. Considering the feasibility and resource constrain, we recruited 50 newly diagnosed PTB patients, their age- and gender-matched 50 HHC and 50 PTB patients who completed treatment a year before. CVD risk factors were compared using chi-square or Fisher exact test. Interleukins-6 (IL-6), interferon-gamma (INF-γ), highly specific - C reactive protein (hs-CRP), and carotid intima-media thickness (CIMT) were compared using ANOVA or Kruskal-Wallis test. Results Most participants from each group belonged to lower socio-economic strata and were males (40/50). Alcohol intake was higher among newly diagnosed and treatment-completed PTB patients (82.5% vs 72.5%). Excess salt intake (58%) was present more in newly diagnosed PTB patients. General and abdominal obesity were seen more among HHC (64% and 84%) and treatment-completed PTB patients (50% and 74%). IL-6 was higher in newly diagnosed PTB patients, whereas INF-γ and hs-CRP were higher in treatment-completed PTB patients. The largest proportion of those having high CIMT values was also in the treatment-completed PTB patients. Conclusion Levels of immune markers hint at the role of inflammation due to TB disease being related to the high CIMT values among the newly diagnosed and treatment-completed PTB patients. CVD risk was higher among TB patients even if they had completed treatment and were declared cured.

Abstract
BACKGROUND Mycobacterium tuberculosis causes tuberculosis (TB), an infectious lung disease. There is mounting evidence linking low lipid levels to a variety of human diseases, including TB. Cholesterol, mainly due to its involvement in heart disease, gets more attention in recent years. The objectives of the study were to look into the link that connects hypolipidemia to the existence of pulmonary/extrapulmonary TB; we have tried to find the link in relation to patients who have been recently diagnosed with TB as well as in those who are having TB in the long term. MATERIALS AND METHODS An observational study was performed on TB patients attending respiratory medicine at the Saveetha Medical College and Hospital, Chennai, Tamil Nadu, India, from February 2021 to January 2022, and their lipid levels were tested from patients with consent and correlated. Student's t-test was applied to the obtained data. To convey quantitative data, measurements such as mean along with standard deviation were applied, and a p-value of 0.05 was considered statistically significant. RESULTS This research included 80 subjects, 40 of whom were diagnosed with TB, and the rest (40 controls) were deemed healthy. The age group with the highest low lipid levels in pulmonary TB was 40-50 years. A chi-square test of association was conducted; this test revealed that the fraction of TB patients having lower than normal levels of total cholesterol (p = 0.0001), triglyceride level (p = 0.006), high-density lipoprotein (p = 0.009), low-density lipoprotein (p = 0.006), and body mass index (p = 0.000) was statistically significantly higher in contrast to the control group. Thus, there was a significant correlation between a higher prevalence of hypolipidemia in patients with pulmonary tuberculosis (PTB) and normal healthy individuals. CONCLUSIONS We observed a strong relationship between hypolipidemia and TB, indicating that patients with low lipid levels tend to have severe inflammation as compared to patients with normal lipid levels.

Statins Use in Patients with Cardiovascular Diseases and COVID-19 Outcomes: An Italian Population-Based Cohort Study. J Clin Med 2022; 11:jcm11247492. [PMID: 36556112 PMCID: PMC9781425 DOI: 10.3390/jcm11247492] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND The role of statins among patients with established cardiovascular diseases (CVDs) who are hospitalized with COVID-19 is still debated. This study aimed at assessing whether the prior use of statins was associated with a less severe COVID-19 prognosis. METHODS Subjects with CVDs infected with SARS-CoV-2 and hospitalized between 20 February 2020 and 31 December 2020 were selected. These were classified into two mutually exclusive groups: statins-users and non-users of lipid-lowering therapies (non-LLT users). The relationship between statins exposure and the risk of Mechanical Ventilation (MV), Intensive Care Unit (ICU) access and death were evaluated by using logistic and Cox regressions models. RESULTS Of 1127 selected patients, 571 were statins-users whereas 556 were non-LLT users. The previous use of statins was not associated with a variation in the risk of need of MV (Odds Ratio [OR]: 1.00; 95% Confidence Intervals [CI]: 0.38-2.67), ICU access (OR: 0.54; 95% CI: 0.22-1.32) and mortality at 14 days (Hazard Ratio [HR]: 0.42; 95% CI: 0.16-1.10). However, a decreased risk of mortality at 30 days (HR: 0.39; 95% CI: 0.18-0.85) was observed in statins-users compared with non-LLT users. CONCLUSIONS These findings support the clinical advice for patients CVDs to continue their treatment with statins during SARS-CoV-2 infection.

Abstract
BACKGROUND Although the incidence of tuberculosis is higher in men than in women, the relationship of sex with tuberculosis treatment outcomes has not been adequately studied. METHODS We performed a retrospective cohort study and a systematic review and meta-analysis of observational studies during the last 10 years to assess sex differences in clinical and microbiological outcomes in tuberculosis. RESULTS In our cohort of 2894 Taiwanese patients with drug-susceptible pulmonary tuberculosis (1975 male and 919 female), male patients had higher adjusted hazards of 9-month mortality due to all causes (hazard ratio, 1.43 [95% confidence interval (CI), 1.03-1.98]) and infections (1.70 [1.09-2.64]) and higher adjusted odds of 2-month sputum culture positivity (odds ratio [OR], 1.56 [95% CI, 1.05-2.33]) compared with female patients. Smear positivity at 2 months did not differ significantly (OR, 1.27 [95% CI, .71-2.27]) between the sexes. Among 7896 articles retrieved, 398 were included in our systematic review describing a total of 3 957 216 patients. The odds of all-cause mortality were higher in men than in women in the pooled unadjusted (OR, 1.26 [95% CI, 1.19-1.34]) and adjusted (1.31 [1.18-1.45]) analyses. Men had higher pooled odds of sputum culture (OR, 1.44 [95% CI, 1.14-1.81]) and sputum smear (1.58 [1.41-1.77]) positivity, both at the end of the intensive phase and on completion of treatment. CONCLUSIONS Our retrospective cohort showed that male patients with tuberculosis have higher 9-month all-cause and infection-related mortality, with higher 2-month sputum culture positivity after adjustment for confounding factors. In our meta-analysis, male patients showed higher all-cause and tuberculosis-related mortality and higher sputum culture and smear positivity rates during and after tuberculosis treatment.

Abstract
Background There is an urgent need for novel therapeutic strategies for reversing COVID-19-related lung inflammation. Recent evidence has demonstrated that the cholesterol-lowering agents, statins, are associated with reduced mortality in patients with various respiratory infections. We sought to investigate the relationship between statin use and COVID-19 disease severity in hospitalized patients. Methods A retrospective analysis of COVID-19 patients admitted to the Johns Hopkins Medical Institutions between March 1, 2020 and June 30, 2020 was performed. The outcomes of interest were mortality and severe COVID-19 infection, as defined by prolonged hospital stay (≥ 7 days) and/ or invasive mechanical ventilation. Logistic regression, Cox proportional hazards regression and propensity score matching were used to obtain both univariable and multivariable associations between covariates and outcomes in addition to the average treatment effect of statin use. Results Of the 4,447 patients who met our inclusion criteria, 594 (13.4%) patients were exposed to statins on admission, of which 340 (57.2%) were male. The mean age was higher in statin users compared to non-users [64.9 ± 13.4 vs. 45.5 ± 16.6 years, p <0.001]. The average treatment effect of statin use on COVID-19-related mortality was RR = 1.00 (95% CI: 0.99–1.01, p = 0.928), while its effect on severe COVID-19 infection was RR = 1.18 (95% CI: 1.11–1.27, p <0.001). Conclusion Statin use was not associated with altered mortality, but with an 18% increased risk of severe COVID-19 infection.

Abstract
Background: Lipids play a central role in the pathogenesis of tuberculosis (TB). The effect of serum lipid levels on TB treatment (ATT) outcomes and their association with serum inflammatory markers have not yet been characterized. Methods: Our retrospective cohort study on drug-susceptible TB patients, at the National Taiwan University Hospital, assessed the association of baseline serum lipid levels such as low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC) and triglycerides (TG) with all-cause and infection-related mortality during first 9 months of ATT and baseline inflammatory markers namely C-reactive protein (CRP), total leukocyte count (WBC), and neutrophil-lymphocyte ratio (NL ratio). Results: Among 514 patients, 129 (26.6%) died due to any-cause and 72 (14.0%) died of infection. Multivariable Cox-regression showed a lower adjusted hazard ratio (aHR) of all-cause mortality in the 3rd tertiles of HDL (aHR 0.17, 95% CI 0.07-0.44) and TC (aHR 0.30, 95% CI 0.14-0.65), and lower infection-related mortality in the 3rd tertile of HDL (aHR 0.30, 95% CI 0.14-0.65) and TC (aHR 0.30, 95% CI 0.14-0.65) compared to the 1st tertile. The 3rd tertiles of LDL and TG showed no association in multivariable analysis. Similarly, 3rd tertiles of HDL and TC had lower levels of baseline inflammatory markers such as CRP, WBC, and NL ratio using linear regression analysis. Body mass index (BMI) did not show evidence of confounding or effect modification. Conclusions: Higher baseline serum cholesterol levels were associated with lower hazards of all-cause and infection-related mortality and lower levels of inflammatory markers in TB patients. BMI did not modify or confound this association.

Spannella F, Giulietti F, Bordicchia M, Burnett JC, Sarzani R. Association Between Cardiac Natriuretic Peptides and Lipid Profile: a Systematic Review and Meta-Analysis. Sci Rep 2019; 9:19178.

Abstract
Cardiac natriuretic peptides (NPs) play a fundamental role in maintaining cardiovascular (CV) and renal homeostasis. Moreover, they also affect glucose and lipid metabolism. We performed a systematic review and meta-analysis of studies investigating the association of NPs with serum lipid profile. A PubMed and Scopus search (2005–2018) revealed 48 studies reporting the association between NPs and components of lipid profile [total cholesterol (TC), low-density lipoprotein cholesterol (LDLc), high-density lipoprotein cholesterol (HDLc) and triglycerides (TG)]. Despite high inconsistency across studies, NPs levels were inversely associated with TC [k = 32; pooled r = −0.09; I2 = 90.26%], LDLc [k = 31; pooled r = −0.09; I2 = 82.38%] and TG [k = 46; pooled r = −0.11; I2 = 94.14%], while they were directly associated with HDLc [k = 41; pooled r = 0.06; I2 = 87.94%]. The relationship with LDLc, HDLc and TG lost significance if only studies on special populations (works including subjects with relevant acute or chronic conditions that could have significantly affected the circulating levels of NPs or lipid profile) or low-quality studies were taken into account. The present study highlights an association between higher NP levels and a favorable lipid profile. This confirms and extends our understanding of the metabolic properties of cardiac NPs and their potential in CV prevention.

Natural Killer Response and Lipo-Metabolic Profile in Adults with Low HDL-Cholesterol and Mild Hypercholesterolemia: Beneficial Effects of Artichoke Leaf Extract Supplementation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:2069701. [PMID: 30723511 PMCID: PMC6339758 DOI: 10.1155/2019/2069701] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Revised: 11/28/2018] [Accepted: 12/27/2018] [Indexed: 11/17/2022]
Abstract
The aim of the present study is to evaluate the effects of 60-day artichoke leaf extract (ALE) supplementation (250mg, twice daily) on cytokines levels, natural killer cell (NK) response, and lipo-metabolic profile (HDL, LDL, and total-cholesterol, triglycerides (TG), ApoB, ApoA, lipid accumulation product (LAP), glucose, insulin, and homeostasis model assessment of insulin resistance (HOMA-IR)) in twenty adults (9/11 males/females, age=49.10 ± 13.74 years, and BMI=33.12 ± 5.14 kg/m2) with low HDL-C and mild hypercholesterolemia. Hierarchical generalized linear model, adjusted for sex, BMI, and age, has been used to evaluate pre-post treatment changes. A significant increase for HDL-C (β=0.14, p=0.0008) and MCP-1 (β=144.77, p=0.004) and a significant decrease for ApoB/ApoA (β=-0.07, p=0.03), total-C/HDL-C ratio (β=-0.58, p<0.001), and NK response at stimulus low (β=0.43, p=0.04), medium (β=0.40, p<0.001), and high (β=0.42, p=0.001) have been found. These results support the benefits of ALE supplementation on metabolic profile.

Abstract
BACKGROUND AND AIMS Laboratory studies on human adipose tissue and differentiated adipocytes indicate that natriuretic peptides (NPs) affect lipid metabolism and plasma cholesterol. Few previous clinical studies in non-elderly populations found associations between NPs in the physiological range and cholesterol. AIM evaluate the association between NT-proBNP and lipid profile in very elderly hospitalized patients characterized by a wide range of NT-proBNP levels. METHODS AND RESULTS Cross-sectional study on 288 very elderly patients hospitalized for medical conditions, in which increased NT-proBNP levels are very common. NT-proBNP, total cholesterol (TC), HDL cholesterol (HDLc) and triglycerides were collected just few days before discharge. Patients taking lipid-lowering drugs and patients with an admission diagnosis of acute heart failure were excluded. Calculated LDL-cholesterol (LDLc) was used for the analyses. Mean age: 87.7 ± 6.2 years; female prevalence (57.3%). Median NT-proBNP: 2949 (1005-7335) pg/ml; mean TC: 145.1 ± 40.3 mg/dl; mean HDLc: 38.4 ± 18.6 mg/dl; median triglycerides: 100 (75-129) mg/dl; mean LDLc: 84.0 ± 29.5 mg/dl. We found negative correlations between NT-proBNP and both TC and LDLc (Rho = -0.157; p = 0.008 and Rho = -0.166; p = 0.005, respectively), while no correlations emerged between NT-proBNP and HDLc (Rho = -0.065; p = 0.275) or triglycerides (Rho = -0.009; p = 0.874). These associations were confirmed considering NT-proBNP tertiles. The inverse association between NT-proBNP and LDLc was maintained even after adjusting for confounding factors. CONCLUSION Our real-life clinical study supports the hypothesis that NPs play a role on cholesterol metabolism, given the association found between LDLc and NT-proBNP even in very elderly patients where NT-proBNP values are often in the pathological range.

Effects of home-based bench step exercise on inflammatory cytokines and lipid profiles in elderly Japanese females: A randomized controlled trial. Arch Gerontol Geriatr 2015; 61:443-51. [PMID: 26228714 DOI: 10.1016/j.archger.2015.06.017] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2015] [Revised: 06/19/2015] [Accepted: 06/24/2015] [Indexed: 11/26/2022]
Abstract
PURPOSE The purpose of the current study was to investigate the effects of a 12-week home-based bench step exercise program on inflammatory cytokines and lipid profiles in elderly females. METHODS Sixty-two postmenopausal females (65-85 years of age) were randomized to either the bench step exercise group (n=31) or the control group (n=31). The subjects in the bench step exercise group were instructed to perform bench step exercises at the exercise intensity corresponding to lactate threshold (LT), three times per day 10-20 min each session, for a goal of ≥140 min/week at home for 12 weeks. At baseline and 12 weeks, circulating levels of nine inflammatory cytokines (high-molecular-weight adiponectin, interleukin-4 [IL-4], IL-5, IL-6, IL-8, IL-15, tumor necrosis factor-α [TNF-α], TNF-β and interferon-γ [IFN-γ]) and serum lipids including high-density lipoprotein cholesterol (HDL-C) were measured. RESULTS The bench step training at the LT significantly increased HDL-C levels and decreased IFN-γ concentrations in the subjects with lower (< 63 mg/dL) baseline HDL-C levels (p<0.05). The change in IFN-γ inversely correlated with the change in HDL-C in the exercise group (ρ=-0.56, p<0.01), whereas this association was not observed in the control group. Additionally, principal component analysis-derived index of what we called "inflammatory status factor" was inversely associated with the changes in HDL-C in the exercise group. CONCLUSION The bench step exercise-induced reduction in the IFN-γ levels may partially explain the degree of improvement in the HDL-C levels with the exercise program.

Abstract
INTRODUCTION We aimed to investigate the relationship between radiological extent and serum biochemical changes and body mass index (BMI) in patients with pulmonary tuberculosis (PTB) and pneumonia and to determine the usefulness of C-reactive protein (CRP) in clinical discriminative diagnosis. MATERIAL AND METHODS One hundred fifteen patients with tuberculosis (group 1), 70 patients with pneumonia (group 2) and 30 healthy controls (group 3) were included in this case-control study. RESULTS Total cholesterol (TC, p < 0.001 in group 1; p = 0.011 in group 2), high-density lipoprotein (HDL, p < 0.001), albumin (ALB, p < 0.001) and BMI (p < 0.001) values were significantly lower group 1 and group 2 than group 3. Erythrocyte sedimentation rate (ESR), leucocyte (LEU) and CRP were higher in group 2 than group 1 and group 3 (p < 0.001). As important point; triglyceride (TG) and BMI were significantly lower in group 1 than group 2 (p < 0.001). In group 1; BMI, HDL, TG, total protein (TP) and albumin were found to decrease, while CRP and ESR increased as the radiological stage increased (p < 0.05). But no significant difference was found in levels of TC and LDL (p > 0.05). In group 2; BMI, TC, HDL, LDL, TP and ALB were observed to decrease, while LEU, CRP and ESR increased as the radiological stage increased (p < 0.05). But no significant difference was found in levels of TG (p > 0.05). The best serum CRP cut-off value in differential diagnosis of tuberculosis and pneumonia was defined as 9.4. CONCLUSIONS The acute phase response occurring in tuberculosis and pneumonia determines the severity of the disease, leads to a decrease of serum levels of lipoproteins and BMI, and is correlated with the radiological extent. The CRP and ESR were found to be useful in differential diagnosis of tuberculosis and pneumonia.

Abstract
AIM To explore whether routinely assessed biochemical markers tested on admission will predict 3 predefined adverse outcomes for hospitalized elderly patients: discharge to a long-term care facility, in-hospital mortality, and prolonged hospital length of stay (> 14 days). METHODS A prospective observational study of elderly patients (aged ≥ 75 years) admitted to an acute-care geriatric ward over a 6-month period. Patients were assessed on admission and baseline characteristics were collected. Activities of daily living were assessed by the Barthel Index and cognitive function by the abbreviated mental test. Results from biochemical markers tested on admission were downloaded from the pathology laboratory database using patient details. Patients were followed-up with until discharge or in-hospital mortality. RESULTS A total of 392 patients formed the study population. Mean (standard deviation) age was 83.2 (± 5.5) years and 283 (72%) patients were men. Thirty-eight (10%) patients were discharged to a long-term care facility, 134 (34%) had a prolonged hospital length of stay, and 33 (8%) died in the hospital. Results from testing 5 biochemical markers independently predicted in-hospital mortality: hypoalbuminemia (adjusted odds ratio [OR], 2.5; 95% CI, 0.9-6.7; P = 0.04), low total cholesterol level (adjusted OR, 2.9; 95% CI, 1.3-6.3; P = 0.01), hyperglycemia (adjusted OR, 2.9; 95% CI, 1.2-7.4; P = 0.02), high C-reactive protein level (adjusted OR, 4.2; 95% CI, 1.3-13.4; P = 0.01), and renal impairment (adjusted OR, 3.8; 95% CI, 1.7-8.7; P = 0.002). High C-reactive protein level independently predicted prolonged hospital length of stay (OR, 1.7; 95% CI, 1.1-2.9; P = 0.03). Hypoalbuminemia predicted discharge to a long-term care facility independent of confounding factors except for physical dysfunction (OR, 2.4; 95% CI, 1.1-5.1; P = 0.03). Significance was reduced after adjustment for Barthel Index score (OR, 1.9; 95% CI, 0.9-4.1; P = 0.08). CONCLUSION Testing of routinely assessed biochemical markers on admission predicted adverse hospital outcomes for elderly patients. Their inclusion in a standardized prediction tool may help to create interventions to improve such outcomes.

Abstract
AIM Observational studies in the elderly have shown that some of the classical cardiovascular (CV) risk factors are difficult to interpret. Thus, our study investigated whether increased aortic stiffness is associated with higher mortality risk in both the diabetic and non-diabetic elderly before and after adjusting for geriatric confounders such as inflammation (sedimentation rate, C-reactive protein, orosomucoid levels, leukocyte count) and denutrition parameters (body weight, body mass index [BMI], plasma albumin and prealbumin). METHODS In a cohort of 324 (84 men) hospitalized elderly subjects, including 255 non-diabetic and 69 diabetic subjects, aortic stiffness was assessed by carotid-femoral pulse wave velocity (PWV) together with CV risk factors. Subjects were studied over a 2-year mean follow-up period, thus enabling evaluation of long-term all-cause mortality. RESULTS A total of 105 subjects died during the follow-up. Kaplan-Meier curves showed a significantly higher mortality in the diabetics (P=0.024). Multivariate Cox analyses differed for non-diabetic subjects and diabetics. In the former, the hazard ratio (HR) for an increase of 1 SD (with confidence intervals) was 1.36 (1.07-1.72) for PWV, 0.73 (0.52-1.01) for plasma albumin and 0.63 (0.45-0.89) for BMI. In diabetic patients, the HR was 1.60 (1.02-2.50) for leukocyte count, 1.75 (1.03-2.96) for orosomucoid levels and 0.32 (0.15-0.68) for BMI. CONCLUSION In this very elderly population, although marginally significant on crude analysis, PWV, but not systolic or pulse pressure, was a powerful determinant of total mortality after taking into account the important role of type 2 diabetes. In diabetics, inflammation and denutrition predominated over mechanical factors.

Abstract
BACKGROUND Type 2 diabetes usually occurs in the context of obesity and associated insulin resistance. Current treatment recommendations are based on lifestyle modifications and incremental drug therapy. However, this approach could lead to inappropriate priorities upon ageing, when diabetes may be compounded by malnutrition and reduced insulin resistance. METHODS We prospectively evaluated glycaemic and nutritional parameters in 146 consecutive diabetic patients (age 82.5 +/- 7.3 years, mean +/- sd) admitted to our geriatric service. We also implemented nutritional support therapy and a drug therapy adjustment protocol. Oral hypoglycaemic agent withdrawal was attempted in cases of good glycaemic control (HbA(1c) < 7.5% (<47 mmol/mol) or fasting blood glucose < 7.5 mmol/l). RESULTS Mean BMI and HbA(1c) were 29.6 +/- 7.1 kg/m(2) and 6.9 +/- 1.2% (52 +/- 9 mmol/mol), respectively. Of the patients, 51.4% were taking 1-3 oral hypoglycaemic agents, 30.8% were on insulin and 9.6% on were on insulin and oral hypoglycaemic therapy. Low Mini Nutritional Assessment scores and serum marker levels indicated a high prevalence of malnutrition and/or chronic disease, even in obese patients. Mini Nutritional Assessment scores were positively associated with HbA(1c) values. Among patients treated by oral hypoglycaemic agents, complete drug withdrawal was achieved in 65.8%, much more often than new treatments were added (P = 0.002). Glycaemic control did not worsen after approximately 30 days, despite in-hospital nutritional therapy. Successful oral hypoglycaemic therapy withdrawal was associated with lower Mini Nutritional Assessment scores. CONCLUSIONS Malnutrition is highly prevalent in elderly diabetic inpatients and, paradoxically, contributes to 'good' glycaemic control. Malnutrition should be screened for in these patients and, when present, should prompt a revision in diet and drug therapy. In particular, the possibility of reducing unnecessary drug therapy should be considered.

Abstract
OBJECTIVES Aims of the study were 1) to investigate the association of C-reactive protein (CRP) with lipid (i.e. total, LDL, and HDL cholesterol, triglycerides) concentrations, and to evaluate their predictive value for mortality in very old subjects. DESIGN Cross-sectional and longitudinal analyses in a prospective cohort study. SETTING Participants. Data are from 336 community-dwelling subjects aged > or = 80 years old enrolled in the "Invecchiamento e Longevità nel Sirente" (ilSIRENTE) study. MEASUREMENTS High sensitivity CRP and lipid concentrations were measured at the baseline clinical visit. High sensitivity CRP concentrations were measured by ELISA assessment. Mortality outcome was evaluated over a 24-month follow-up. RESULTS Participants had a mean age of 85.8 (SD 4.8) years old. Spearman's correlations showed significant (p values < 0.01) inverse correlations between CRP and lipid parameters (except triglycerides). Adjusted linear regressions between CRP and lipid parameters concentrations showed no significant association in participants aged lower than 85 years old (all p values > 0.5). In the older age group, significant inverse associations of CRP with total (p=0.002), LDL (p=0.007), and HDL cholesterol (p=0.002) were found, even after adjustment for potential confounders. Adjusted Cox proportional hazard models demonstrated that CRP was the only biomarker significantly predictive of mortality, independently of age and lipid parameters. CONCLUSION An inverse relationship of total, LDL, and HDL cholesterol with CRP is present in very old persons. The prognostic value of CRP is particularly important among very old persons whereas lipid parameters tend to lose their capacity to predict events.

Serum total cholesterol, HDL-C and LDL-C concentrations significantly correlate with the radiological extent of disease and the degree of smear positivity in patients with pulmonary tuberculosis. Clin Biochem 2006; 40:162-6.

Abstract
BACKGROUND Low serum total cholesterol (TC) concentrations in patients with pulmonary tuberculosis (PTB) have been demonstrated. It was shown that a cholesterol-rich diet might accelerate the sterilization rate of sputum cultures in PTB patients. It is known that smear positivity might be related to the radiological extent of disease (RED) in PTB patients. OBJECTIVE We hypothesized that there might be a relationship between initial serum TC concentrations; the degree of RED (DRED) and the degree of smear positivity (DSP) in PTB patients. METHOD Eighty-three PTB patients and 39 healthy controls were included in the study. Serum TC, TG, HDL-C, VLDL-C and LDL-C concentrations were determined in all subjects. PTB patients were classified for their chest X-ray findings as minimal/mild, moderate and advanced. Correlations between serum lipid concentrations, DRED and DSP (0, 1+, 2+, 3+, 4+) were investigated. PTB patients and controls were also compared for serum lipid concentrations. RESULTS Significant differences between PTB patients and controls were detected for serum TC, HDL-C and LDL-C concentrations. On stepwise logistic regression analysis, DRED was found as one of the significant independent predictors of serum TC levels. We also found significant correlations between DRED and serum HDL-C concentrations (r=-0.60, p=0.0001) and between DRED and serum LDL-C concentrations (r=-0.28, p=0.011). There were also significant correlations between DSP and serum lipid concentrations. CONCLUSION Our study suggests that serum TC, HDL-C and LDL-C concentrations are generally lower in patients with PTB than those in healthy controls. In addition, changes in these parameters might be related to DRED and DSP in PTB patients.

Abstract
To assess the prevalence of metabolic syndrome (MS) and estimates of global risk by Framingham Risk Score in young subjects with acute myocardial infarction (MI), we assessed metabolic parameters and global risk assessment in 165 consecutive subjects who presented with myocardial infarction prior to 45 years of age. Nearly 80% of subjects were overweight or obese and at least one cardiovascular risk factor was present in 96% of patients. MS with or without overt diabetes was present in nearly two thirds of subjects. Excluding subjects with diabetes, the mean 10-year Framingham Risk Score estimate in the total cohort was 9.3%, with only 17.1% of subjects having a 10-year risk greater than 20%. Only 28% of subjects with MS had a Framingham Risk Score greater than 20%. Although MS is present in nearly two thirds of young patients with premature myocardial infarction, the Framingham Risk Score appears to underestimate global cardiovascular risk in this population.

Abstract
BACKGROUND The association between total serum cholesterol and health outcomes among older adults is controversial. The objective of the present study was to determine within a cohort of acutely hospitalized disabled elderly patients whether total cholesterol predicts recovery from disability in basic activities of daily living (ADL). METHODS Patients (3150) 65 years old or older admitted to 81 acute care units in Italy and presenting with ADL disability at hospital admission were included in this study. ADL disability was defined as need of assistance or total dependence in one or more ADLs (eating, dressing, personal hygiene, transferring, and toilet use). Recovery was defined as no disability at hospital discharge in any of the five ADLs considered. RESULTS Mean age of study participants was 80.5 +/- 7.2 years, and 1305 (41.1%) were men. The rate of recovery from ADL disability was 14.5% for participants with total cholesterol < 200 mg/dL (n = 306/2108), 20.2% for those with total cholesterol between 200 and 239 mg/dL (n = 144/713), and 23.1% for those with total cholesterol > or = 240 mg/dL (n = 76/329). After adjustment for potential confounders, relative to that of patients with cholesterol < 200 mg/dL, risk ratios for recovery were 1.31 for participants with cholesterol between 200 and 239 mg/dL (95% confidence interval [CI], 1.07-1.62) and 1.36 (95% CI, 1.04-1.79) for those with cholesterol > or = 240 mg/dL. After exclusion of 769 patients with total cholesterol < 145 mg/dL, the risk ratios (compared with those for participants with cholesterol < 200 mg/dL) for recovery were 1.33 (95% CI, 1.07-1.66) for participants with cholesterol between 200 and 239 mg/dL and 1.41 (95% CI, 1.06-1.88) for patients with cholesterol > or = 240 mg/dL. CONCLUSIONS Among hospitalized disabled older adults, elevated levels of cholesterol are associated with increased rate of recovery from ADL disability.

High interleukin-6 plasma levels are associated with low HDL-C levels in community-dwelling older adults: the InChianti study. Atherosclerosis 2006; 192:384-90.

Abstract
BACKGROUND Low levels of high density lipoprotein cholesterol (HDL-C) are associated with increased incidence of coronary heart disease (CHD). A better understanding of the mechanisms leading to low HDL-C and CHD is essential for planning treatment strategies. Clinical studies have demonstrated that cytokines might affect both concentration and composition of plasma lipoproteins, including HDLs. METHODS We investigated the possible association between low HDL-C levels, defined as < or =10th gender specific percentile, and circulating markers of inflammation (IL-1beta, TNF-alpha, IL-6, IL-10, IL-18, and CRP) in a population of 1044 community dwelling older Italian subjects from the InChianti study. RESULTS Using logistic regression analysis we demonstrated that IL-6 levels (III versus I tertile, OR: 2.10; 1.10-3.75), TG (III versus I tertile OR: 27.45; 8.47-88.93), fasting insulin (III versus I tertile OR: 2.84; 1.50-5.42), and age (OR: 1.038; 1.002-1.075) were associated with low HDL-C independent of smoking, BMI, waist circumference, hypertension, diabetes, physical activity, alcohol intake, oral hypoglycaemics, CRP, IL-18, and TNF-alpha levels. The adjusted attributable risk of low HDL-C in the exposed group (III tertile of IL-6) was 54%. CONCLUSIONS The present study provides the epidemiological evidence that besides triglycerides, fasting insulin, and age, IL-6 is one of the main correlates of low HDL-C levels in older individuals.

Abstract
BACKGROUND In several studies, it was shown that there was a marked decrease in serum levels of HDL-C during infection and inflammation in general. In particular, a decrease in the level of serum HDL-C was also shown in pneumonia. Correlations between inflammatory markers such as acute phase proteins, cytokines and serum HDL-C levels were shown. However, there are no studies indicating a correlation between serum HDL-C levels and the radiological extent of the disease (RED) in community-acquired pneumonia (CAP). AIM We hypothesized that there could be a relationship between serum HDL-C levels and RED in CAP. MATERIALS AND METHODS A case-controlled study, including 97 patients with CAP and 45 healthy subjects, was performed. Chest X-rays of CAP patients were scored for RED, and correlations were investigated between RED scores, serum lipid parameters, the erythrocyte sedimentation rate (ESR) and serum albumin levels. RESULTS The mean serum HDL-C level was lower in CAP patients than in controls. A significant and negative correlation between RED scores (REDS) and serum HDL-C levels was detected (r = -0.64, P = 0.0001). There were also significant correlations between REDS and other lipid parameters. Significant correlations between ESR and serum HDL-C levels and between ESR and other serum lipid parameters were also found. CONCLUSION It appears that serum HDL-C levels are generally lower in CAP cases than in healthy controls. Serum HDL-C levels and serum albumin levels might decrease and serum total cholesterol/HDL-C ratios and log (TG/HDL-C) values might increase proportionally with RED in CAP patients. These results might have some significance for individuals having long-standing and/or recurrent pneumonia and other cardiovascular risk factors.

Abstract
BACKGROUND Lipoproteins and their subfractions are associated with the incidence of atherosclerotic diseases. In patients with coronary artery disease (CAD), low serum concentrations of high density lipoprotein (HDL) and high low-density lipoproteins (LDL) are correlated to myocardial infarction and cardiovascular death. There is growing evidence indicating that those lipoprotein factors are related to the inflammatory process in atherogenesis. METHODS We investigated in a median follow up of 3.9 years the association of HDL, apolipoprotein A-I (apoA-I), LDL, apolipoprotein B (apoB), and triglycerides with the incidence of a combined endpoint (myocardial infarction and cardiovascular death) and their relation to markers of inflammation in 1298 patients with angiographically documented CAD. RESULTS In univariate analysis, serum concentrations of apoA-I were significantly and inversely related to the combined endpoint, whereas serum concentrations of LDL, apoB, and triglycerides were not. HDL was not significantly related to the endpoint in univariate analyses (p=0.057). Multivariate analyses showed that only apoA-I is an independent predictor. ApoA-I (and HDL) was significantly related to markers of inflammation. CONCLUSION Serum apoA-I levels were an independent predictor for fatal and non-fatal cardiovascular events in patients with CAD. This may be related to its anti-inflammatory effect.

Abstract
Epidemiological studies have enhanced the importance of high-density lipoprotein (HDL) as a risk factor for CAD, as well as disability and frailty in the oldest elderly. Therefore, HDL and molecules involved in HDL metabolism seem to be attractive candidates for longevity-promoting factors. A series of observational studies has demonstrated that the predominance of the larger, more lipid-rich HDL2 subclass is a reproducible phenotype among centenarians. This finding was recently evolved by nuclear magnetic resonance technology in quantification of lipoprotein particle size. However, results of investigations into the mechanisms underlying the lipoprotein profiles in the oldest elderly have been conflicting. Genetic variation in cholesteryl ester transfer protein (CETP), which is a carrier protein in reverse cholesterol transport, was demonstrated to have no association with longevity in one study, but to have positive impacts on large HDL particles and longevity in another. Regarding environmental factors, acute phase reactant and nutritional status are frequently associated with HDL-C levels in the oldest elderly, however, the causality of the association remains to be elucidated. Determination of the association between cognitive function and HDL in the oldest elderly is also a future task. To obtain further insight into the mechanistic roles of low HDL in the pathophysiology of geriatric syndrome, a much greater effort should be invested in this research field.

Abstract
BACKGROUND AND AIMS The aim of this study was to verify the hypothesis that a combined measurement of albumin and HDL-C might predict total mortality in institutionalized frail older residents. METHODS Participants were 344 older subjects (272 F, 72 M), living in the "Istituto Riposo Anziani" (I.R.A.), a nursing-home located in Padova, North-east Italy. Functional status, comorbidity, and clinical chemistry parameters were evaluated at entry. All-cause mortality was evaluated after 2 and 4 years. The sample was divided into 4 groups by using the 50 degrees percentile of albumin and HDL-C as cut-off value. The mortality odds ratio (OR) was estimated by multivariate logistic regression analysis. RESULTS Total mortality was 36.8% after 2 years and 51.8% after four years. A trend toward an increase in mortality from group 1 to 4 was observed (p for trend: 0.01). The OR for 2 and 4 years mortality was 3.83 (95% CI 1.86-7.58) and 2.66 (95% CI 1.37-5.17), respectively, in group 4 compared with group 1, after adjustment for age, gender, number of chronic diseases, functional status, BMI, diabetes, dementia, stroke, CHD, CHF, hypertension, depression, COPD, and total cholesterol levels. CONCLUSIONS Among frail older nursing-home residents, simple measurement of serum albumin and HDL-C levels may be useful in identifying varying degrees of frailty.

Abstract
BACKGROUND The possible relationship between serum total cholesterol (TC) levels and outcome following ischemic stroke is still controversial. We evaluated the association between TC levels and 30-day mortality in a sample of older patients with acute ischemic stroke. METHODS We enrolled 490 older patients with severe ischemic stroke consecutively admitted to University Hospital's Internal Medicine or Geriatrics Department. Stroke type was classified according to the Oxfordshire Community Stroke Project. The data recorded included clinical features, medical history, electrocardiogram, and blood analyses. Patients were divided into three groups by TC levels: group I (TC<4.1 mmol/L), group II (TC 4.1-5.2 mmol/L), and group III (TC>5.2 mmol/L). RESULTS The overall mortality was 27.7%. Mortality was higher in patients with low TC levels (47.4%) compared with those with normal and high TC levels (23.0% and 24.1%, respectively). The odds ratio (OR) for short-term death was 2.17 (95% confidence interval [CI] 1.22-3.85) in group I compared with group III, after adjustment for age and gender. This result did not change after adjustment for possible confounders (OR 2.87; 95% CI 1.23-6.68). A similar trend was observed after adjustment for the Oxfordshire classification, age, and gender (OR 1.67; 95% CI 0.83-3.33). CONCLUSIONS Short-term mortality following ischemic stroke is higher in older participants with low TC levels, independent of a large number of factors. Low TC levels might be useful in identifying frail older participants at high risk of stroke short-term mortality.

Abstract
Clinical data show that a 1% increase in serum concentrations of high-density lipoprotein cholesterol (HDL-C) can decrease cardiovascular risk by 2% to 3%. Therefore, mechanisms affecting the level and functionality of high-density lipoprotein (HDL) and its constituents are being investigated as targets for the rational development of drugs to prevent or treat cardiovascular disease. High-density lipoprotein-related research may also increase our understanding of the link between atherosclerosis and metabolic disorders. This report and update of the HDL Working Group discusses HDL metabolism and reverse cholesterol transport, impaired HDL as a marker and a cause of proatherogenic states, and experimental and current approaches to HDL-related therapy.

Abstract
PURPOSE Although total cholesterol levels among middle-aged persons correlate with long-term mortality from all causes, this association remains controversial in older persons. We explored whether total cholesterol levels were independently associated with in-hospital mortality among elderly patients. METHODS We analyzed data from a large collaborative observational study, the Italian Group of Pharmacoepidemiology in the Elderly (GIFA), which collected data on hospitalized patients. A total of 6984 patients aged 65 years or older who had been admitted to 81 participating medical centers during four survey periods (from 1993 to 1998) were enrolled. Patients were divided into four groups based on total cholesterol levels at hospital admission: <160 mg/dL (n = 2115), 160 to 199 mg/dL (n = 2210), 200 to 239 mg/dL (n = 1719), and >or=240 mg/dL (n = 940). RESULTS Patients (mean [+/- SD] age, 78 +/- 7 years) were hospitalized for an average of 15 +/- 10 days. The mean total cholesterol level was 186 +/- 49 mg/dL. A total of 202 patients died during hospitalization. Mortality was inversely related to cholesterol levels (<160 mg/dL: 5.2% [110/2115]; 160-199 mg/dL: 2.2% [49/2210]; 200-239 mg/dL: 1.6% [27/1719]; and >or=240 mg/dL: 1.7% [16/940]; P for linear trend <0.001). After adjustment for potential confounders (demographic characteristics, smoking, alcohol use, indicators of nutritional status, markers of frailty, and comorbid conditions), low cholesterol levels continued to be associated with in-hospital mortality. Compared with patients who had cholesterol levels <160 mg/dL, the odds ratios for in-hospital mortality were 0.49 (95% confidence interval [CI]: 0.34 to 0.70) for participants with cholesterol levels of 160 to 199 mg/dL, 0.41 (95% CI: 0.26 to 0.65) for those with cholesterol levels of 200 to 239 mg/dL, and 0.56 (95% CI: 0.32 to 0.98) for those with cholesterol levels >or=240 mg/dL. These estimates were similar after further adjustment for inflammatory markers and after excluding patients with liver disease. CONCLUSIONS Among older hospitalized adults, low serum cholesterol levels appear to be an independent predictor of short-term mortality.

Abstract
OBJECTIVES To investigate the relationship between low cholesterol and mortality in older persons to identify, using information collected at a single point in time, subgroups of persons with low and high mortality risk. DESIGN Prospective cohort study with a median follow-up period of 4.9 years. SETTINGS East Boston, Massachusetts; New Haven, Connecticut; and Iowa and Washington counties, Iowa. PARTICIPANTS Four thousand one hundred twenty-eight participants (64% women) age 70 and older at baseline (mean 78.7 years, range 70-103); 393 (9.5%) had low cholesterol, defined as < or =160 mg/dl. MEASUREMENTS All-cause mortality and mortality not related to coronary heart disease and ischemic stroke. RESULTS During the follow-up period there were 1,117 deaths. After adjustment for age and gender, persons with low cholesterol had significantly higher mortality than those with normal and high cholesterol. Among subjects with low cholesterol, those with albumin> 38 g/L had a significant risk reduction compared with those with albumin < or =38 g/L (relative risk (RR) = 0.57; 95% confidence interval (CI) = 0.41-0.79). Within the higher albumin group, high-density lipoprotein cholesterol (HDL-C) level further identified two subgroups of subjects with different risks; participants with HDL-C <47 mg/dl had a 32% risk reduction (RR = 0.68; 95% CI = 0.47-0.99) and those with HDL-C > or =47 mg/dl had a 62% risk reduction (RR = 0.38; 95% CI = 0.20-0.68), compared with the reference category; those with albumin < or =38 g/L and HDL-C <47 mg/dl. CONCLUSIONS Older persons with low cholesterol constitute a heterogeneous group with regard to health characteristics and mortality risk. Serum albumin and HDL-C can be routinely used in older patients with low cholesterol to distinguish three subgroups with different prognoses: (1) high risk (low albumin), (2) intermediate risk (high albumin and low HDL-C), and (3) low risk (high albumin and high HDL-C).

Abstract
Patients with chronic renal impairment (CRI) are at greatly increased risk for premature vascular disease; however, little is known about its evolution. This paper describes a cohort of patients with CRI and reports study design, baseline demographic and biochemical data, and comparisons with two contemporaneous age- and sex-matched control groups, one with established coronary artery disease and the other without overt vascular disease. Among 369 individuals (median age, 63 years; range, 18 to 88 years; 67% men) with CRI, 34% had a history of vascular disease and 21% had electrocardiographic left ventricular hypertrophy (LVH). Even in those with mild renal impairment (serum creatinine < 2.1 mg/dL), approximately one third had vascular disease and 12% had LVH. A history of hypertension was present in 76% of the CRI group, but as compared with controls, systolic and diastolic blood pressures were not elevated. Low-density lipoprotein (LDL) cholesterol concentration also was not elevated, but CRI was associated with elevated serum triglyceride and plasma homocysteine levels and reduced high-density lipoprotein (HDL) cholesterol, hemoglobin, and serum albumin concentrations. Across the spectrum of CRI, more severe renal dysfunction was associated with lower levels of diastolic blood pressure, LDL and HDL cholesterol, albumin, and hemoglobin, but increased levels of plasma homocysteine. This cross-sectional analysis shows that vascular disease is common in individuals with mild CRI attending a nephrology program and also suggests trends in the levels of a number of potential vascular risk factors with respect to severity of renal dysfunction. These results will be further quantified in a prospective biennial follow-up.

Abstract
Recent studies have proposed an association between hyperlipidemia and venous thromboembolism (VTE). We review the epidemiological evidence linking dyslipidemia with VTE and examine several possible underlying mechanisms. We discuss the possible role of HMG CoA reductase inhibitors (statins) in the prevention and treatment of VTE and suggest future directions for research.

Abstract
BACKGROUND The total cholesterol concentration decreases with age in older people. The reasons for this phenomenon are controversial. This study investigated the hypothesis that poor health status is a determinant of the inverse association between age and cholesterol in older persons. METHODS Cross-sectional study of 2,486 (53% women) older medical patients (> or =65 years) admitted at 35 centers of the Gruppo Italiano di Farmacovigilanza nell'Anziano (GIFA) study in Italy. Total cholesterol was measured on the first day after admission to the hospital. Disease burden and comorbidity were assessed by the Charlson index; low serum albumin and iron were considered markers of frailty and poor health. RESULTS In men there was a significant, inverse age-cholesterol relationship (-0.97 mg/dl per year, p<0.001). In women the association was nonlinear and cholesterol significantly decreased after the age of 75 (-0.95 mg/dl per year, p<0.005). In multiple linear regression analysis, indicators of poor health accounted for almost two thirds of the crude effect of age on the cholesterol level in both men and women (adjusted coefficients for age were: for men, -0.38 mg/dl per year, p = 0.044; for women after the age of 75, -0.37 mg/dl per year, p = 0.205). The unadjusted probability of having low cholesterol significantly increased with age among men (p for trend <0.005). In multiple logistic regression, indicators of poor health were strongly associated with low cholesterol in both men and women. After adjusting for indicators of poor health, the association between age and low cholesterol in men was no longer present. CONCLUSION These findings suggest that the age-dependent reduction of cholesterol often observed in clinical and epidemiologic studies is substantially explained by the effect of poor health status. Low cholesterol in older persons may be a marker of poor health.

Abstract
BACKGROUND Some alterations of the lipoprotein profile have been associated with cerebrovascular disease. Recently, it has been suggested that cerebrovascular disease might play a role in the pathogenesis of both vascular dementia (VD) and Alzheimer's disease (AD). Nevertheless, the possible association of dyslipidemias with VD or AD is still a controversial issue. METHODS We investigated the lipoprotein profile in 100 older patients with vascular dementia (VD; no degrees: 60) or Late Onset Alzheimer's Disease (LOAD; no degrees: 40). The patients were compared with 54 community dwelling non-demented older controls. RESULTS After adjustment for functional status, blood sedimentation rate, and serum albumin levels, no differences in lipoprotein profile emerged between the three groups, with the exception of HDL-C that was lower in VD compared with controls. Low HDL-C (< 45 mg/dL) was associated with VD (O.R.: 6.52, C.I. 95%: 1.42-30.70 vs controls, and 4.31, C.I. 95%: 0.93-19.82 vs LOAD), after multivariate adjustment. No differences in plasma lipid levels emerged between the three groups after stratification for apo E4 genotype. CONCLUSIONS In this cross-sectional study low HDL-C levels are associated with VD, but not with LOAD, in a sample of older subjects.
