Upper gastrointestinal symptoms and therapies in elderly out-patients, users of non-selective NSAIDs or coxibs.

BACKGROUND: The association between coxib or non-steroidal anti-inflammatory drug use with gastrointestinal symptoms and drug prescriptions in ambulatory elderly patients is not well defined. AIM: To evaluate the association between non-steroidal anti-inflammatory drug NSAID and coxib use with gastrointestinal symptoms and therapies in elderly subjects managed by their general practitioner. MATERIALS: The study was carried out by 133 general practitioners in Italy. By using a structured interview, sex, age, physical function, current medications, new drug prescriptions and upper gastrointestinal symptoms were registered from all elderly subjects who were referred to their general practitioners during a 2-week period. The numbers of hospitalizations, gastrointestinal bleeding events and gastrointestinal diagnostic procedures occurring during the last 6-month period were recorded. RESULTS: Included in this study were 5515 elderly subjects. The overall prevalence of drug use was 92%. Musculo-skeletal drugs were taken by 15% of patients; NSAIDs were taken by 6%, and coxibs by 3% of patients. A significantly higher prevalence of upper gastrointestinal symptoms was observed in elderly NSAID users compared with coxib users and non-users of musculo-skeletal drugs (44% vs. 33% vs. 32% respectively, P = 0.001). The prescriptions of drugs for acid-related disorders were significantly higher in patients who were concomitantly taking NSAID rather than coxibs (13% vs. 6%, P < 0.01). The prescriptions of drugs for acid-related disorders were significantly associated with the presence of upper gastrointestinal symptoms (OR = 1.7, 95% CI = 1.6-1.9), previous gastrointestinal disorders (OR = 1.1, 95% CI = 1.0-1.3) and NSAID use (OR = 1.5, 95% CI = 1.0-2.2), but no coxib use. CONCLUSION: In this elderly population, upper gastrointestinal symptoms and prescriptions for gastroenterological drugs were higher in non-steroidal anti-inflammatory drug users than coxib users and non-users of musculo-skeletal drugs.

Effect of diet and red wine consumption on serum total antioxidant capacity (TAC), dehydroepiandrosterone-sulphate (DHEAS) and insulin-like growth factor-1 (IGF-1) in Italian centenarians.

The traditional mediterranean diet is associated with a hope for longer survival. It has also been shown that the red wine possesses a protective effect against the oxidative stress. We studied TAC, the DHEAS and the IGF-1 in a group of 26 healthy centenarians, 17 women and 9 men, of the age range of 100--105 years. Furthermore, we analyzed also serum urate and bilirubin levels between drinkers and abstainers. Most of centenarian subjects have been moderate wine consumers (<500 ml/day of red wine). These subjects were subdivided as follows: (i) Group A: those who had maintained the style of their dietary habits as compared to the previous years (n=3 males, 10 females); (ii) Group B: those who actually consumed a diet being deficient compared to that of the previous years, but remained moderate drinkers of red wine (n=3 males, 4 females); and (iii) Group C: those who actually consumed a diet being deficient compared to that of the previous years, and at the same time, were abstainers in wine consumption (n=3 males, 3 females). The results show that in men three of the studied parameters decreased from Group A to C to considerable extents, as follows (mean+/-S.D.). TAC: 302.4+/-32.3; 142.0+/-24.1 and 96.4+/-20.1 micromol/l; DHEAS: 3.35+/-0.81; 2.52+/-0.18 and 1.34+/-0.14 micromol/l; IGF-1: 85.7+/-6.7; 76.6+/-6.7 and 65.6+/-2.6 ng/ml, respectively. For the same parameters, the results in the women were: TAC: 258.4+/-12.2; 182.1+/-14.0 and 107.6+/-10.0 micromol/l; DHEAS: 3.85+/-0.16; 2.34+/-0.19 and 2.05+/-0.04 micromol/l; IGF-1: 89.7+/-6.7; 76.6+/-4.7 and 64.2+/-2.7 ng/ml, respectively. We did not find any significant difference in the other serum parameters between drinkers (n=14) and abstainers (n=3) (urate: 267.6+/-52.9, and 289.5+/-80.1; bilirubin: 9.81+/-4.29 and 7.18+/-2.89 micromol/l, respectively). Our data suggest that the deteriorated diet caused a reduction of TAC, DHEAS and IGF-1 in the centenarians. However, red vine consumption exerted a protective effect against this trend, even if this protection is not reaching statistical significance in some cases (in men), which is due most probably to the lower number of male subjects in the study.

Healthy centenarian subjects: the effect of red wine consumption on liver function tests.

Liver function is well maintained with increasing age. The aim of our study was to investigate if long-term moderate (<or=500 ml/day) red wine consumption influences the most common laboratory tests of liver function in healthy centenarians. Wine consumption habits were classified as moderate red wine drinkers (D) (<or=500 ml/day of red wine consumption in the past and present) (no.=3 males, 16 females) and abstainers (A) who never consumed red wine or alcoholic beverages (no.=1 male, 4 females). None were heavy drinkers. Laboratory tests revealed low levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). AST was higher in A (Mean+/-SE=8.40+/-0.32 U/l) in comparison to D (Mean+/-SE=6.25+/-0.72 U/l), but this difference was not statistically significant. Total-bilirubin (Tbil), alkaline phosphatase (AlkP), gamma- glutamyltransferase (GGT) and pseudocholinesterase (CHE) were in the normal range, and there was no difference between D and A. We conclude that red wine consumption in centenarians had no negative effect on circulating liver enzyme activities.

Effectiveness and safety of cholinesterase inhibitors in elderly subjects with Alzheimer's disease: a "real world" study.

Clinical trials have demonstrated the efficacy of cholinesterase inhibitors (ChEI) in improving cognitive status and disability in subjects with mild to moderate Alzheimer's disease (AD). However, little is known about the effectiveness of ChEI in clinical practice, and no large clinical trials comparing different ChEI are available at present. Aim of this study was to evaluate safety and effectiveness of ChEI in a sample of elderly outpatients diagnosed with mild to moderate AD. We selected 407 subjects for ChEI treatment (donepezil,rivastigmine or galantamine). Their cognitive function was evaluated by means of the mini mental state examination (MMSE), and the global functional status was estimated by using the activities of daily living (ADL) and the instrumental activities of daily living (IADL) scales at baseline (To), then after 1 (T1), 3 (T2) and 9 months (T3), respectively. T3 follow-up was completed by 212 subjects. The patients were considered as responders (R), if the MMSEscore at T2 was unchanged or improved, if compared to that of T0. In 35 patients (8.6 %)treatment was withdrawn because of mostly gastrointestinal adverse events. Compared to the other drugs, donepezil was associated with a lower incidence of withdrawals due to adverse events. Subjects who completed T3 follow-up (age 78 +/- 6 years, MMSE scores 18.8 +/- 3.9) showed an increase at T2 of 0.7 +/- 2.7 (p = 0.001) and a decrease at T3 of -0.6 +/- 3.4 (p = 0.008) in the MMSE scores, as compared to To . The ADL and IADL scores did not show significant changes at T2; however, both decreased significantly at T3. The patients Rat-T2 showed a better cognitive and functional outcome at T3 , compared to the nonresponders(NR-at-T2), displaying values of MMSE R-at-T2 0.4 +/- 3.1 vs. NR-at-T2 -3.0 +/- 2.5, p = 0.001, and ADL values of -0.3 +/- 1.2 vs. -0.7 +/- 1.3, p = 0.03, respectively. No significant difference was found in the changes of MMSE scores between donepezil and rivastigmine (galantamine was not included in the comparison due to the small number of treated subjects). In conclusion, in this sample of elderly subjects with mild to moderate AD,treated with ChEI, a small but significant decline in cognitive and functional status was observed after 9 months. Subjects who showed a good response to treatment after 3 months, had a better cognitive and functional outcome at 9 months. No significant difference in cognitive outcome was found between drugs, while donepezil was better tolerated.

Isolated ambulatory hypertension is common in outpatients referred to a hypertension centre.

The present investigation was aimed at determining the prevalence and the blood pressure (BP) profile of isolated ambulatory hypertension, defined as an elevated ambulatory BP with normal office blood pressure, in a series of 1488 consecutive outpatients referred for routine clinical evaluation of suspected or established arterial hypertension. All patients underwent both office BP (OBP) measurement by a physician and 24-h ambulatory blood pressure monitoring (ABPM). Using OBP values (cutoff for diagnosis of hypertension >/=140/90 mmHg) and daytime ABPM (cutoff for diagnosis of hypertension >/=135/85 mmHg), patients were classified into eight subgroups. In the whole series we found that, independent of treatment status, the prevalence of isolated ambulatory hypertension exceeded 10%. More importantly, 45.3% of individuals who presented with normal OBP values, showed elevated BP at ABPM. Night-time BP, 24-h pulse pressure, and BP variability were significantly higher in isolated ambulatory hypertensives than in normotensive or in white-coat hypertensive individuals. Therefore, isolated ambulatory hypertension is characterized by a blood pressure profile that is similar to that observed in sustained hypertension. These findings suggest that isolated ambulatory hypertension is very common and probably the indications for ABPM should be more extensive in outpatients referred to hypertensive centre.

Epidemiological profile of symptomatic osteoarthritis in older adults: a population based study in Dicomano, Italy.

OBJECTIVES: To assess the prevalence of hand, hip, and knee osteoarthritis (OA) in an older Italian community dwelling population and its association with disability. METHOD: A cross sectional survey of the whole community aged 65 years and over, was carried out in Dicomano, a small rural town in Tuscany, Italy. Subjects were screened by geriatricians for major chronic conditions, including hip, knee, and hand OA, using diagnostic algorithms based on the American College of Rheumatology (ACR) clinical criteria. A rheumatologist examined subjects who screened positive. Disability was assessed by a World Health Organisation questionnaire. RESULTS: 697 of 864 eligible subjects (81% of the eligible population) were screened. OA of the knee, hand, or hip was identified by clinical ACR criteria respectively in 159, 139, and 81 subjects, and was confirmed by the rheumatologist in 158/182 (87%), 75/101 (74%), and 63.2% of cases. The estimated prevalence was 29.8%, 14.9%, and 7.7%, respectively. Only hip OA was significantly associated with disability in basic activities of daily living. CONCLUSIONS: About one third of community dwelling older people are affected by symptomatic peripheral OA. Hip OA was strongly associated with disability.

Features of excessive alcohol drinking in older adults distinctively captured by behavioral and biological screening instruments. An epidemiological study.

The entire > or =65-year-old population living in a small Italian town, where alcohol use is almost ubiquitous, was assessed with a frequency-quantity questionnaire for alcohol intake and with two screening instruments for alcohol problems, the CAGE questionnaire and the MCV-gammaGT test. Aim of the study was to assess whether these instruments identify different subsets of subjects with alcohol problems. Of the 649 participants, 19.1% were at-risk drinkers (average intake > 40 g/day in men and > 20 g/day in women). Both the screening instruments were positive in only a minority of participants. Of the 377 drinkers, 53 gave > or =1 affirmative response to the CAGE questionnaire, whereas 24 had a positive MCV-gammaGT test. The concordance between positive CAGE questionnaire and MCV-gammaGT test was limited to seven subjects (kappa = 0.10), and these tests identified subjects who differed for several health and psychosocial characteristics. Participants aged > or =75 years drank less, but had similar prevalence of CAGE and MCV-gammaGT positive markers as compared to younger participants. In conclusion, excessive drinking is common in the elderly. Screening tests based on behavioral and biological markers identify two different sets of subjects with possible alcohol problems. This might indicate the opportunity to use these instruments in conjunction.

Cumulative effect of complete left bundle-branch block and chronic atrial fibrillation on 1-year mortality and hospitalization in patients with congestive heart failure. A report from the Italian network on congestive heart failure (in-CHF database).

BACKGROUND: Many clinical variables have been proposed as prognostic factors in patients with congestive heart failure. Among these, complete left bundle-branch block and atrial fibrillation are known to impair significantly left ventricular performance in patients with congestive heart failure. However, their combined effect on mortality has been poorly investigated. The aim of this study was to determine whether left bundle-branch block associated with atrial fibrillation had an independent, cumulative effect on mortality for congestive heart failure. METHODS AND RESULTS: We analysed the Italian Network on congestive heart failure (IN-CHF) Registry that was established by the Italian Association of Hospital Cardiologists in 1995. One-year follow-up data were available for 5517 patients. Complete left bundle-branch block and atrial fibrillation were associated in 185 (3.3%) patients. In this population the cause of congestive heart failure was dilated cardiomyopathy (38.4%), ischaemic heart disease (35.1%), hypertensive heart disease (17.3%), and other aetiologies (9.2%). This combination of electrical defects was associated with an increased 1-year mortality from any cause (hazard ratio, HR: 1.88; 95% CI 1.37-2.57) and sudden death (HR: 1.89; 95% CI 1.17-3.03) and 1-year hospitalization rate (HR: 1.83; 95% CI 1.26-2.67). CONCLUSIONS: In patients with congestive heart failure, the contemporary presence of left bundle-branch block and atrial fibrillation was associated with a significant increase in mortality. This synergistic effect remained significant after adjusting for clinical variables usually associated with advanced heart failure. We can conclude that this combination of electrical disturbances identifies a congestive heart failure specific population with a high risk of mortality.

Cardiac and vascular remodeling in older adults with borderline isolated systolic hypertension: the ICARe Dicomano Study.

Although borderline isolated systolic hypertension (ISH), defined as a blood pressure of 140 to 159/<90 mm Hg, is a proven cardiovascular risk factor, the major clinical trials on treatment of ISH have used a cutoff of 160 mm Hg. Moreover, no data exist on the cardiovascular modifications associated with borderline ISH. Therefore, we compared subjects with borderline ISH to subjects with diastolic hypertension (diastolic blood pressure > or =90 mm Hg) or ISH. Community-dwelling residents (age > or =65 years) of a small town in Italy (Dicomano) underwent extensive clinical examination, echocardiography, carotid ultrasonography, and applanation tonometry. Only untreated subjects were included in this analysis: 95 with diastolic hypertension, 87 with borderline ISH, and 43 with ISH. Despite lower systolic and mean pressures in borderline ISH, left ventricular mass was similar to that in diastolic hypertension. In univariate and multivariate analysis, pulse pressure but not systolic pressure was related to left ventricular mass. Borderline ISH subjects had a tendency to greater carotid cross-sectional area and stiffness index than did diastolic hypertensive subjects despite lower mean carotid pressure, whereas the number of atherosclerotic plaques was similar in the 2 groups. Pulse pressure but not systolic pressure was independently related to carotid remodeling. In our community-based, older population, individuals with borderline ISH had a similar prevalence of left ventricular hypertrophy and carotid atherosclerosis as that of subjects with diastolic hypertension, despite lower systolic and mean pressures. Among blood pressure values, pulse pressure was the single or strongest independent predictor of cardiovascular remodeling.

Accuracy of equations for predicting stature from knee height, and assessment of statural loss in an older Italian population.

We determined the applicability of deriving the stature from knee height in an older Italian population, and, in the same population, we assessed longitudinally the change in stature over a 6-year interval. The standing stature and knee height in a supine position were measured in the entire home-dwelling older (65 + years) population of a small Italian town (N = 606). Stature measured in 1989 and in 1995 was used to assess longitudinal changes in 258 subjects of the same population. Stature derived from knee height was greater than measured stature in this population and in the two sexes. This difference disappeared when subjects with evident kyphosis were excluded. From 1989 to 1995, stature decreased by 1.7+/-3.0 cm, with women showing a larger decrement than men. Stature estimated from knee height is more accurate than measured stature in subjects with kyphosis. In accordance with previous studies, stature decreases with aging, and such height loss is greater in women than in men.

Changes in renal autacoids and hemodynamics associated with aging and isolated systolic hypertension.

The aging kidney is characterized by a decrease in renal blood flow and glomerular filtration rate mainly due to glomerulosclerosis. Nevertheless, even in the presence of these changes, the kidney maintains its functionality until advanced age. However, there is a tendency towards greater renal vasoconstriction in the elderly as compared with young individuals. This occurs either in physiological circumstances such as physical exercise, or in disease manifestations, such as the effective circulatory volume depletion that develops, for example, in heart failure. This tendency may be secondary to the reduction of renal autacoid modulatory capacity, particularly at the vasodilating prostaglandin level. In an acute experimental model we could demonstrate that, in the healthy elderly, the renal response to adrenergic activation by mental stress is characterized by a prolonged and pronounced vasoconstriction. In addition to this, in elderly patients affected by isolated systolic hypertension, we demonstrated an impairment of renal hemodynamic and humoral adaptation capacity in response to adrenergic activation and blood pressure increase. In the presence of sudden blood pressure increase, the kidney of these patients responds with a passive vasodilation and a glomerular filtration rate increase without any activation of humoral modulatory substances. The impairment in renal adaptation capacity may predispose these patients to renal injury, particularly in the presence of the many hypertensive peaks which characterize everyday life of elderly individuals. In conclusion, these results show that renal adaptation capacity of elderly patients with isolated systolic hypertension is completely lost. Further studies will elucidate whether antihypertensive treatment per se, or specific classes of antihypertensive drugs, are able to revert this impairment.

Prevalence of symptomatic hand osteoarthritis in community-dwelling older persons: the ICARe Dicomano study. Insufficienza Cardiaca negli Anzizni Residenti a Dicomano.

OBJECTIVE: To assess whether the American College of Rheumatology (ACR) classification criteria for hand osteoarthritis (OA) may be used successfully to detect hand OA in population-based studies and to estimate the prevalence of hand OA in an elderly italian population. DESIGN: This study was part of a cross-sectional population-based survey on heart failure in the elderly (ICARe Dicomano study). All community-dwelling citizens aged >65 were considered eligible and screened by expert geriatricians for the presence of major chronic conditions, including hip, knee and hand OA, using custom-made algorithms based on standard criteria. Those subjects who screened positively were subsequently assessed by a rheumatologist. RESULTS: Six hundred and ninety-seven subjects (80% of the eligible population) underwent a general examination by a geriatrician. One hundred and thirty-nine of these met the ACR criteria for hand OA at screening: 22 subjects with isolated first carpometacarpal (CMC) joint OA and 117 with generalized nodal OA. 74.2% of the diagnoses were confirmed in the 101 participants re-examined in a second phase by a rheumatologist (19 subjects presented with isolated thumb-base OA and 56 with nodal OA). The estimated prevalence in the cohort was 14.9%. CONCLUSIONS: The ACR clinical criteria for hand OA may be used in population studies, especially when the burden of this disease is evaluated.

Cardiopulmonary resuscitation of older, inhospital patients: immediate efficacy and long-term outcome.

OBJECTIVE: To determine the independent effect of advancing age on prognosis after cardiopulmonary resuscitation (CPR). DESIGN AND SETTING: Retrospective analysis of clinical records of patients who received CPR in a geriatric department equipped with an intensive care unit. PATIENTS: A total of 245 patients (146 men, 99 women; mean age, 70+/-11 yrs) received CPR. Of these, 221 had a cardiocirculatory arrest (CA) in the intensive care unit and 24 had a CA in the general ward of the department. Acute myocardial infarction was the most frequent admission diagnosis. INTERVENTIONS: CPR according to standard guidelines in all cases. MEASUREMENTS AND MAIN RESULTS: Immediate, short-term (hospital discharge), and long-term (median follow-up, 31.5 months; range, <1-124 months) survival. Older patients had a lower immediate survival (<70 yrs [72/137] 52.6% vs. > or =70 yrs [43/108] 39.4%; p < .05) and, less frequently, ventricular tachycardia/ fibrillation (VT/VF) as a cause of CA. VT/VF bore the lowest immediate mortality rate (19/104; 18.3%) as compared with asystole/complete heart block (66/102; 64.7%) or pulseless electrical activity (40/49; 81.6%; p < .001). Acute myocardial infarction, acute heart failure, hypotension, and occurrence of CA in the intensive care unit were also univariate predictors of unfavorable, immediate prognosis. However, in a multiple logistic analysis model, the mechanism of CA (asystole/complete heart block or pulseless electrical activity vs. VT/VF), acute myocardial infarction, heart failure, and hypotension were independent predictors of unfavorable immediate prognosis, whereas advancing age was not. Similarly, after initially successful CPR, short-term survival was independently associated with acute myocardial infarction, hypotension before CA, initial rhythm at CA, and need for mechanical ventilatory support after CPR, but not with age. Longterm survival (42 patients; 17.2% of the original cohort; median survival, 32 months) was also independent of age, whereas it was negatively associated with heart failure. CONCLUSION: Immediate, short- and long-term prognosis after in hospital CPR is independent of age, at least when possible confounders are simultaneously taken into account.
