Aortic stenosis (AS) may soon become a significant public health issue. Referring elderly suffering from aortic stenosis for a transcatheter aortic valve implantation (TAVI) versus surgical valve replacement might be difficult and requires a multidisciplinary staff. G8 is a geriatric screening scale for frailty, validated in oncogeriatry. We study sensibility and specificity of G8 used by cardiologists in comparison to a comprehensive geriatric assessment (CGA) performed by geriatrician. Prospective study, from February to July 2015, in Bordeaux university Hospital, France. Every elderly admitted for a TAVI had a G8 scale performed by cardiologist and CGA by a geriatrician in blind. Comorbidities were assessed using Cumulative Illness Rating Scale in his geriatric version (CIRS-G). CGA was abnormal if: MMSE <24/30 or GDS ≥7/15 or ADL ≤5/6 or IADL ≤7/8 or TUG ≥20 seconds or if malnutrition was noticed. G8 was abnormal if ≤14/17. We calculated sensibility, specificity, positive and negative predictive value in comparison to gold-standard CGA. 49 patients were included (55.1% women, mean age 84.8 years old). Nearly half of the patients (48.96%) had multiple comorbidities (CIRS G score >3 for at least three items excluding the cardiology item). 38 CGA were abnormal (77.55%) and 41 G8 (83.67%). G8 had a sensibility of 100% (IC 95% [0.9-1]), a specificity of 72.7% (IC 95% [0.43-0.9]), a positive predictive value of 92.6% and a negative prospective value of 100% (IC: 95%). G8 scale seems to be an efficient geriatric screening tool for frailty in elderly undergoing TAVI in comparison to CGA. Simple and useful, G8 scale could be performed by cardiologists in older patients with AS for identifying patients with a geriatric risk profile in consultation before surgery. Further studies with bigger samples are needed to confirm these results.

Background: In the general geriatric population, programs linking geriatric evaluation with interventions are effective for improving functional status and survival of the patients. Whether or not these interventions improve health related quality of life (HRQoL) or overall survival (OS) in older patients with cancer is not yet clear. Indeed, randomized data on the effect of such interventions on survival and HRQoL are rare and conflicting. We describe the rationale and design of a phase III multicenter trial aimed at assessing the efficacy of geriatric intervention in the management of elderly patients with cancer., Methods/design: Approximately 1200 patients, 70 years and older, considered in need of a geriatric intervention based on the G8 screening tool will be randomized into two intervention arms. The 'Usual-care' arm involves standard oncological care based on pre-defined oncological protocols. In addition to the standard oncological care, the 'Case-management' arm involves a multidimensional geriatric assessment and interventions tailored for the patient. Efficacy will be assessed using a co-primary endpoint encompassing OS and HRQoL., Discussion: This trial has been designed to assess whether focused geriatric case management can either improve OS or HRQoL in elderly cancer patients considered in need of geriatric assessment., Trial Registration: Clinicaltrials.gov ID: NCT02704832 .

Background: Although non-drug interventions are widely used in patients with Alzheimer's disease, few large scale randomized trials involving a long-term intervention and several cognitive-oriented approaches have been carried out. ETNA3 trial compares the effect of cognitive training, reminiscence therapy, and an individualized cognitive rehabilitation program in Alzheimer's disease to usual care., Methods: This is a multicenter (40 French clinical sites) randomized, parallel-group trial, with a two-year follow-up comparing groups receiving standardized programs of cognitive training (group sessions), reminiscence therapy (group sessions), individualized cognitive rehabilitation program (individual sessions), and usual care (reference group). Six hundred fifty-three outpatients with Alzheimer's disease were recruited. The primary efficacy outcome was the rate of survival without moderately severe to severe dementia at two years. Secondary outcomes were cognitive impairment, functional disability, behavioral disturbance, apathy, quality of life, depression, caregiver's burden, and resource utilization., Results: No impact on the primary efficacy measure was evidenced. For the two group interventions (i.e. cognitive training and reminiscence), none of the secondary outcomes differed from usual care. The larger effect was seen with individualized cognitive rehabilitation in which significantly lower functional disability and a six-month delay in institutionalization at two years were evidenced., Conclusions: These findings challenge current management practices of Alzheimer's patients. While cognitive-oriented group therapies have gained popularity, this trial does not show improvement for the patients. The individualized cognitive rehabilitation intervention provided clinically significant results. Individual interventions should be considered to delay institutionalization in Alzheimer's disease.

Objective: The G8 is a screening test to identify frail elderly patients with cancer. Objectives were to design and evaluate the performance of alternative tests taking into account other predictive domains for frailty., Methods: We conducted a literature review to identify predictive factors of frailty. Using a Delphi consensus, we collected 24 European experts' opinions to validate the most relevant items to improve the G8. Alternative tests were created and performance assessed on a development population (ONCODAGE cohort). The highest performing test was compared to the G8, and validated through both an internal and an external population validation (Aquitaine Geriatric Oncology cohort)., Results: The study population consisted of 1435 patients (ONCODAGE cohort) and 364 patients (Aquitaine Geriatric Oncology cohort). Twenty-three experts validated two items with a strong consensus (>75%): modification of the threshold for the G8 polypharmacy item to six drugs per day and replacement of the G8 item on neuropsychological problems by four Instrumental Activities of Daily Living (IADL) items predictive of incident dementia, creating three modified G8 tests (addition of either item, or both). Only the G8 IADL-modified test had better performance than the G8 when tested on the ONCODAGE cohort: sensitivity=77%, specificity=67%. This test was validated on the internal (sensitivity=78%, specificity=71%) and external (sensitivity=88%, specificity=69%) validation populations., Conclusion: Adding the four IADL items improves the performance of the G8. We have developed and validated a G8-modified test that is more specific than the G8 to detect frail elderly, while still sensitive and feasible in less than 10 min., (Copyright © 2016 Elsevier Inc.

Purpose: The MNA (Mini Nutritional Assessment) is known as a prognosis factor in older population. We analyzed the prognostic value for one-year mortality of MNA items in older patients with cancer treated with chemotherapy as the basis of a simplified prognostic score., Methods: The prospective derivation cohort included 606 patients older than 70 years with an indication of chemotherapy for cancers. The endpoint to predict was one-year mortality. The 18 items of the Full MNA, age, gender, weight loss, cancer origin, TNM, performance status and lymphocyte count were considered to construct the prognostic model. MNA items were analyzed with a backward step-by-step multivariate logistic regression and other items were added in a forward step-by-step regression. External validation was performed on an independent cohort of 229 patients., Results: At one year 266 deaths had occurred. Decreased dietary intake (p = 0.0002), decreased protein-rich food intake (p = 0.025), 3 or more prescribed drugs (p = 0.023), calf circumference <31 cm (p = 0.0002), tumor origin (p<0.0001), metastatic status (p = 0.0007) and lymphocyte count <1500/mm3 (0.029) were found to be associated with 1-year mortality in the final model and were used to construct a prognostic score. The area under curve (AUC) of the score was 0.793, which was higher than the Full MNA AUC (0.706). The AUC of the score in validation cohort (229 subjects, 137 deaths) was 0.698., Conclusion: Key predictors of one-year mortality included cancer cachexia clinical features, comorbidities, the origin and the advanced status of the tumor. The prognostic value of this model combining a subset of MNA items and cancer related items was better than the full MNA, thus providing a simple score to predict 1-year mortality in older patients with an indication of chemotherapy.

Mild cognitive impairment occurs frequently with ageing, concerning memory complaint, attention and executive dysfunction without any consequence on the activities of daily living. They are strongly linked to the presence of vascular risk factors in adulthood. Nevertheless with the continuous progression of life expectancy, the incidence of dementia drastically increases after sixty-five years of age and the number of old people with dementia is expected to increase by 75% in 2030 in France. Caring for elderly patients with cancer needs to face the possibility of cognitive impairment and its consequences on a good comprehension of diagnosis and treatment and ability to properly take medication. Comprehensive geriatric assessment can help to diagnose cognitive impairment and evaluate the consequences on instrumental activities of daily living (IADL) and activities of daily living (ADL). Home care may be organised with the help of the family or social workers. Physiotherapy and speech rehabilitation are often useful. Assistance for housekeeping, shopping and cooking may be financed by social organisations such as APA in France. Complex cases must be referred to case managers in homes for patients suffering for Alzheimer's disease (MAIA) who liaise between doctors and home carers with good results., (Copyright © 2015.

Treating non-Hodgkin's lymphoma in patients with comorbidities can be challenging because of possible interactions that may alter the treatment efficacy. We conducted a systematic review to determine the impact of comorbidities on various outcomes, evaluate the current data, and provide recommendations for future research. Twenty-one articles were selected. However, the study populations and design were greatly heterogeneous, and the quality of reporting was generally weak. The majority of studies demonstrated significant impact of comorbidity on survival, reporting poorer survival rates for patients with comorbidities compared to those with no comorbidities. However, the existing evidence is limited and of insufficient quality to establish solid conclusions and to guide treatment decisions. Prospective, well-designed studies are warranted.

Background: Geriatric Assessment is an appropriate method for identifying older cancer patients at risk of life-threatening events during therapy. Yet, it is underused in practice, mainly because it is time- and resource-consuming. This study aims to identify the best screening tool to identify older cancer patients requiring geriatric assessment by comparing the performance of two short assessment tools the G8 and the Vulnerable Elders Survey (VES-13)., Patients and Methods: The diagnostic accuracy of the G8 and the (VES-13) were evaluated in a prospective cohort study of 1674 cancer patients accrued before treatment in 23 health care facilities. 1435 were eligible and evaluable. Outcome measures were multidimensional geriatric assessment (MGA), sensitivity (primary), specificity, negative and positive predictive values and likelihood ratios of the G8 and VES-13, and predictive factors of 1-year survival rate., Results: Patient median age was 78.2 years (70-98) with a majority of females (69.8%), various types of cancer including 53.9% breast, and 75.8% Performance Status 0-1. Impaired MGA, G8, and VES-13 were 80.2%, 68.4%, and 60.2%, respectively. Mean time to complete G8 or VES-13 was about five minutes. Reproducibility of the two questionnaires was good. G8 appeared more sensitive (76.5% versus 68.7%, P =  0.0046) whereas VES-13 was more specific (74.3% versus 64.4%, P<0.0001). Abnormal G8 score (HR = 2.72), advanced stage (HR = 3.30), male sex (HR = 2.69) and poor Performance Status (HR = 3.28) were independent prognostic factors of 1-year survival., Conclusion: With good sensitivity and independent prognostic value on 1-year survival, the G8 questionnaire is currently one of the best screening tools available to identify older cancer patients requiring geriatric assessment, and we believe it should be implemented broadly in daily practice. Continuous research efforts should be pursued to refine the selection process of older cancer patients before potentially life-threatening therapy.

Background: Knowledge of functional evolution in dementia is crucial for the patients and their families as well as the clinician., Objective: This review identifies scales and outcomes used to describe the natural history of functional decline and describes the natural history of functional decline in a representative clinical population sample of published studies of patients with Alzheimer's disease (AD)., Methods: A search of three relevant databases was conducted and limited to articles published in English and French between 1998 to March 2012, using the keywords "Dementia", "Activities of Daily Living", "Instrumental Activities of Daily Living", "Functional Impairment", "Prognosis", and "Disease Progression"., Results: The search strategy displayed 683 articles, 20 of which were found to be related to the functional evolution of AD. In these studies, different scales were used to describe the evolution of the functional decline, except for the decline of instrumental activities, for which the Lawton scale was used in all studies. Thus, it is difficult to represent the evolution of the functional decline from a clinical point of view., Conclusion: Relatively little data are available to estimate the functional evolution of AD. A consensus with broadened thought is required to know if the progression of the incapacities in these scales is additive or hierarchical.

Purpose: To determine factors associated with early functional decline during first-line chemotherapy in older patients., Patients and Methods: Patients age ≥ 70 years receiving first-line chemotherapy for cancer were prospectively considered for inclusion across 12 centers in France. Functional decline was defined as a decrease of ≥ 0.5 points on the Activities of Daily Living (ADL) scale between the beginning of chemotherapy and the second cycle. Factors associated with functional decline were sought from pretreatment abbreviated comprehensive geriatric assessment, including ADL, Instrumental ADL (IADL), Mini-Nutritional Assessment (MNA), Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS15), and Timed Get Up and Go (GUG) test, and from comorbidities (Cumulative Illness Rating Scale-Geriatrics), MAX2 index, and baseline biologic and clinical information., Results: Of 364 included patients, 50 experienced functional decline (16.7%; median, 0.5 points). Abnormal preadmission performance status, IADL, GDS15, MMSE, GUG, and MNA were associated with increased likelihood of functional decline (univariate analysis). In the multivariate model adjusted for baseline ADL and MAX2 index, high baseline GDS (odds ratio [OR], 2.16; 95% CI, 1.09 to 4.30; P = .03) and low IADL scores (OR, 2.87; 95% CI, 1.06 to 7.79; P = .04) were independently associated with increased risk of functional decline., Conclusion: Our results outline associations between baseline depression, instrumental dependencies, and early functional decline during chemotherapy for older patients. ADL should be sequentially evaluated early during treatment. Baseline evaluation of GDS15 and IADL may be proposed to anticipate this event.

Background: Many studies have identified advanced age as a barrier to accessing specialized oncological care., Objectives: To identify elements from the literature influencing general practitioners (GPs) in their decisions to refer elderly patients with cancer to oncology teams, and propose focused actions to improve referral processes., Methods: Eligible articles published up to July 2010 identifying factors associated with referral decisions for elderly cancer patients were selected. A quality assessment of each article was performed. All factors identified were considered for possible interventions classified by the Effective Practice and Organisation of Care (EPOC) taxonomy and development of recommendations for referral of elderly patients., Results: Thirty eligible articles were found with only 18 articles specifically exploring factors influencing physicians in the referral of their patients with cancer. Twelve focused on delay to treatment and only two uniquely on elderly patients. Patient age was the main factor associated with referral decisions, but this factor can influence GP's differently depending on the type of cancer. The small size of these studies, heterogeneity of study populations, and diversity of outcome measures used meant that compilation of guidelines based on high-quality evidence was not possible. However, organizational factors hindering decisions to refer are identified and highlighted as crucial for inclusion in intervention programs, specifically to reach GPs in smaller locations or with less experience in collaborating with specialists. For patient-related factors, professional and organizational interventions are necessary, aimed at both GPs and patients to update knowledge of the non-linear relationship between chronological age and a patient's ability to tolerate treatment., Conclusions: First and foremost, this article highlights the scarcity of literature specific to elderly patients with cancer. It also identifies the public health need for better knowledge of the factors for referral of elderly patients. Focussed action proposals are presented to improve knowledge and consequently, optimize the referral process., (Copyright © 2012. Published by Elsevier Ltd.)

Background: The health of the agricultural population has been previously explored, particularly in relation to the farming exposures and among professionally active individuals. However, few studies specifically focused on health and aging among elders retired from agriculture. Yet, this population faces the long-term effects of occupational exposures and multiple difficulties related to living and aging in rural area (limited access to shops, services, and practitioners). However, these difficulties may be counter-balanced by advantages related to healthier lifestyle, richer social support and better living environment. The general aim of the AMI cohort was to study health and aging in elderly farmers living in rural area through a multidisciplinary approach, with a main focus on dementia., Methods/design: The study initially included 1 002 participants, randomly selected from the Farmer Health Insurance rolls. Selection criteria were: being 65 years and older; living in rural area in Gironde (South-Western France); being retired from agriculture after at least 20 years of activity and being affiliated to the Health Insurance under own name. The study started in 2007, with two follow-up visits over 5 years. Baseline visits were conducted at home by a neuropsychologist then by a geriatrician for all cases suspected of dementia, Parkinson's disease and depression (to confirm the diagnosis), and by a nurse for others. A large panel of data were collected through standardised questionnaires: complete neuropsychological assessment, material and social living environment, psychological transition to retirement, lifestyle (smoking, alcohol and diet), medications, disability in daily living, sensory impairments and some clinical measures (blood pressure, depression symptomatology, anxiety, visual test, anthropometry...). A blood sampling was performed with biological measurements and constitution of a biological bank, including DNA. Brain MRI were also performed on 316 of the participants. Finally, the three-year data on health-related reimbursements were extracted from the Health System database (medications, medical and paramedical consultations, biological examinations and medical devices), and the registered Long-Term Diseases (30 chronic diseases 100% covered by the Insurance System)., Discussion: AMI is the first French longitudinal study on health and aging set up in a population of elderly farmers living in rural area through a multidisciplinary approach.

Objectives: To assess the impact of a hygiene-encouragement program on reducing infection rates (primary end point) by 5%., Design: A cluster randomized study was carried out over a 5-month period., Settings and Participants: Fifty nursing homes (NHs) with 4345 beds in France were randomly assigned by stratified-block randomization to either a multicomponent intervention (25 NHs) or an assessment only (25 NHs)., Intervention: The multicomponent intervention was targeted to caregivers and consisted of implementing a bundle of infection prevention consensual measures. Interactive educational meetings using a slideshow were organized at the intervention NHs. The NHs were also provided with color posters emphasizing hand hygiene and a kit that included hygienic products such as alcoholic-based hand sanitizers. Knowledge surveys were performed periodically and served as reminders., Measurements: The primary end point was the total infection rate (urinary, respiratory, and gastrointestinal infections) in those infection cases classified either as definite or probable. Analyses corresponded to the underlying design and were performed according to the intention-to-treat principle. This study was registered (#NCT01069497)., Results: Forty-seven NHs (4515 residents) were included and followed. The incidence rate of the first episode of infection was 2.11 per 1000 resident-days in the interventional group and 2.15 per 1000 resident-days in the control group; however, the difference between the groups did not reach statistical significance in either the unadjusted (Hazard Ratio [HR] = 1.00 [95% confidence interval (CI) 0.89-1.13]; P = .93]) or the adjusted (HR = 0.99 [95% CI 0.87-1.12]; P = .86]) analysis., Conclusion: Disentangling the impact of this type of intervention involving behavioral change in routine practice in caregivers from the prevailing environmental and contextual determinants is often complicated and confusing to interpret the results., (Copyright © 2012 American Medical Directors Association.

Objective: Current chemotherapy protocols for gastric cancer present high toxicity. The FOLFIRI regimen has shown promising results with elderly colorectal cancer patients and for gastric cancer patients but this is the first report on elderly gastric cancer patients., Design: In this multicenter non-randomized phase II trial, we administered the FOLFIRI chemotherapy protocol (irinotecan [180 mg/m(2)], fluorouracil [5-FU] [400 mg/m(2)] and folinic acid 400 mg/m(2) or 200mg/m(2) of l-folinic acid) to patients aged over 70 years with locally-advanced or metastatic gastric cancer combined with Comprehensive Geriatric Assessment (CGA). Responses were assessed at 2 months., Results: Forty-two patients received eight cycles of the FOLFIRI regimen, with 82.5% of patients showing disease control: 10 patients (26%) showing objective (partial or complete) responses and 23 (57.5%) showing stable disease. One-year overall survival (OS) was 41.5% [95%CI 26.5-56.0] and one-year progression-free survival (PFS) was 31.8% [95%CI 18.4-46.1%]. We observed 10 Grade 3/4 hematologic toxicities with one febrile neutropenia. CGA data demonstrated that geriatric functions were not altered by treatment and that nutritional status improved over treatment., Conclusions: Results show excellent disease control and relatively high survival rates with limited toxicity similar to younger patients indicating that this regimen should be considered as a possible treatment in advanced gastric cancer of the elderly., (Copyright © 2011 Elsevier Masson SAS.

Background: Little is known about normal kidney function level and the prognostic significance of low estimated glomerular filtration rate (eGFR) in the elderly., Methods: We determined age and sex distribution of eGFR with both the Modification of Diet in Renal Disease (MDRD) study and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations in 8705 community-dwelling elderly aged ≥ 65 years and studied its relation to 6-year mortality. In a subsample of 1298 subjects examined at 4 years, we assessed annual eGFR decline and clinically relevant markers including microalbuminuria (3-30 mg/mmol creatinine) with diabetes, proteinuria ≥ 50 mg/mmol, haemoglobin <11 g/L or resistant hypertension despite three drugs., Results: Median (interquartile range) MDRD eGFR was 78 (68-89) mL/min/1.73 m(2) in men and 74 (65-83) in women; there were 79 (68-87) and 77 (67-85) for CKD-EPI eGFR, respectively. Prevalence of MDRD eGFR <60 mL/min/1.73 m(2) was 13.7% and of CKD-EPI eGFR was 12.9%. After adjustment for several confounders, only those with an eGFR <45 mL/min/1.73 m(2) had significantly higher all-cause and cardiovascular mortality than those with an eGFR of 75-89 mL/min/1.73 m(2) whatever the equation. In the subsample men and women with an MDRD eGFR of 45-59 mL/min/1.73 m(2), 15 and 13% had at least one clinical marker and 15 and 3% had microalbuminuria without diabetes, respectively; these percentages were 41 and 21% and 23 and 10% in men and women with eGFR <45, respectively. Mean MDRD eGFR decline rate was steeper in men than in women, 1.75 versus 1.41 mL/min/1.73 m(2)/year., Conclusions: Moderately decreased eGFR is more often associated with clinical markers in men than in women. In both sexes, eGFR <45 mL/min/1.73 m(2) is related to poor outcomes. The CKD-EPI and the MDRD equations provide very similar prevalence and long-term risk estimates in this elderly population.

Background: A number of studies have identified advanced age as a barrier to accessing specialised oncological care. Many factors can influence the care provided for elderly patients after a diagnosis of cancer has been established or is suspected. Only one European study has analysed the decision processes leading general practitioners (GPs) to refer elderly patients with cancer to oncologists. The objectives of the current study are to describe the factors that influence these decisions and to identify the particular factors and GP characteristics that are associated with systematic referral of these patients in South-West France., Methods: This is a cross-sectional study on a representative sample of GPs in Aquitaine, South-West France. Questionnaire items were selected using a Delphi consensus approach and sent by post. Two logistic regression models were constructed to investigate GPs' decisions to refer these patients., Results: The response rate obtained was 30%. Half of the general practitioners reported "always" referring their elderly cancer patients to oncologists. More than 75% reported being influenced by patient-related elements (patient and/or family wishes, comorbid factors, unsuitability of invasive investigations, physical and mental autonomy), by cancer-related elements (severity of symptoms, expected side-effects) and an organisational element (whether the general practitioner was used to collaborating with oncologists). Logistic regression analysis showed that cancer site and organisational difficulties in patient management were significantly associated with the decision to refer elderly patients with early-stage cancer. For advanced stages, oncology training, patient age, organisational difficulties in patient management and stage of cancer were significantly associated with the decision to refer elderly patients., Conclusions: Cancer-linked factors and organisational difficulties have been highlighted as influencing the decisions of GPs in the referral of elderly patients to a cancer team. These results highlight the need to implement continuous medical education specific for the management of elderly patients, to better apprehend the nature of these difficulties and to suggest solutions suited to local settings.

The increase in life expectancy combined with the increase in the global incidence of cancers will probably results in an increase in the number of cancers observed in the elderly. The increase in the incidence of prostate cancers in geriatric patients (45% of prostate cancers are diagnosed after 75 years old) is in sharp contrast with the lack of strong scientific data on the topic. By the meantime, oncogeriatrics has been developing for some years now under the guidance of the International Society of Oncogeriatrics. Such an approach aims at palliating the low quality of care of cancers in geriatric patients. The reasons for the low quality of care come from the characteristics of these patients and from the training of the care providers. The authors recall the principles of oncogeriatric evaluation and the classification of patients as it is actually proposed. They describe the main treatments and their results in the geriatric population and they describe the decision process concerning the choice of the treatment. They also suggest some guidelines on the diagnosis of prostate cancer, evaluation of the patients and the treatments of the disease in the elderly. Prostate cancer is almost the perfect model for oncogeriatrics. Urologists should remain the corner stone of its management, whatever the age of their patient.

Lymphoma is a malignant disease that often occurs in elderly patients. Although many treatment options are available, comorbidities and limitations of functional reserves limit their use in frail patients. Still, because of the high sensitivity of disease to these treatments, even reduced doses and schedules may allow long-term disease control or even cure. The question that remains is how to use these treatments while controlling risks. Fortunately, both biological and clinical researches allow for progress that will help clinicians improve treatment strategies. During the last years, interest for research in the elderly with lymphoma has increased. Most of it concerned fit patients but not only. Among those, availability of specific monoclonal antibodies, which improve treatment efficiency without significantly increasing toxicity, appears as a major step forward which should be further developed. Yet, recent data has also been published on other topics including trials on frail patients and specific biological data. Early evaluation of response is also among important topics which should be scrutinized. Overall, recently published results raise hopes for future management of our patients and more is expected soon.

Objective: Observation of insulin use in consecutive hospitalized diabetic older patients in acute care wards with reference to nutritional intakes, measures of functional status, and varying clinical situations., Methods: Prospective case study in a geriatric medicine ward with CGA, dietary intake measure and used insulin dosage., Results: Among 600 inpatients, 90 diabetic subjects were found. Only 12.2 % diabetic patients had MMSE > 23 and 23.3% were unable to eat without assistance. During the stay 54 patients had received insulin. From admission to discharge or death, doses were 0.39 to 0.19 U/kg (SD 0.41-0.15) during palliative care, 0.43 to 0.45 U/kg (SD 0.20-0.20) in the event of failure of oral therapy, 0.38 to 0.42 U/kg (SD 0.18-0.25) if creatinine clearance was 30 ml/min or lower, and 0.38 to 0.27 U/kg (SD 0.24-0.26) in critical diseases. Dietary intake increased in all during the stay with an energy intake close to 20 kCal/kg/d at discharge, except for those in palliative care, who had a final intake of 8.2 kCal/kg/d (SD 9.1)., Conclusion: Insulin treatment guidelines adapted to this frail diabetic population are necessary.

In recent years, geriatricians and oncologists have worked together to evaluate elderly patients with cancer before and during treatment, to estimate the balance between the efficacy and safety of chemotherapy and to upgrade treatment in this population according to their comorbidity and physiological status. The clinical and biological factors of this population need to be assessed in multidisciplinary comprehensive geriatric assessment (CGA) in order to optimize treatment without inducing major adverse effects. We reviewed the nutritional aspects of this evaluation that highlight the impact of undernutrition on poor survival. In this paper we briefly describe tumoral cachexia (molecular and physiological), the impact of undernutrition on cancer prognosis (predictive factors), therapeutic effects of cancer on nutritional status, nutritional indicators (biological, anthropometric) and undernutrition in the elderly (specific needs of this population). The potential for nutritional intervention in geriatric oncology with regard to CGA is explored.

Increasing comorbidity with aging reduces the predictive power of cardiovascular risk factors. From the age of 70 onward, total cholesterol levels decrease, perhaps associated with changes in the composition of some lipoprotein fractions. In subjects older than 75 years, being in the lowest quartile of cholesterol, insulinemia or serum albumin concentrations is associated with increased mortality. Cholesterol levels below 189 mg/dL in subjects older than 75 years should be considered an early sign of unidentified comorbidity or of rapid functional decline. HDL cholesterol levels, rather than total or LDL cholesterol, were inversely associated with increased mortality from ischemic coronary disease and stroke appears to rise as HDL cholesterol levels fall, rather than total or LDL cholesterol. On the other hand, LDL concentrations below 106 mg/dL and HDL concentrations below 36 mg/dL were associated with an increased risk of death from infectious disease. Stroke incidence, in particular, ischemic stroke, is highest in subjects older than 75 years. HDL cholesterol levels above 35 mg/dL appear to have a protective effect against ischemic stroke in subjects younger than 70 years. Two interventional drug studies investigating the effects of two statins (simvastatin and pravastatin) found that in subgroups of subjects older than 75 these drugs were associated with a reduction in all-cause mortality and cardiovascular morbidity, regardless of total cholesterol levels, but had no short-term effect on cognitive function.

Background: In older people, the decrease in muscle mass and strength has a bad effect on functional status. Malnutrition and lack of physical activity exacerbate this phenomenon., Objective: The main purpose of this study was to estimate isokinetic lower limb muscle strength in recovering older subjects on the basis of nutritional status., Design: Twenty-eight elderly subjects hospitalized for an acute event (85.8 +/- 6 years), including 16 malnourished, were enrolled in this study when clinically stable (T0). Re-assessment at one-month was performed in nine after oral supplementation and conventional physiotherapy (T1). The Maximal Peak Torque (MPT) of the ankle plantar flexors was estimated in concentric mode at 30 and 60 degrees /s. The MPT of the knee flexors and extensors was evaluated in the same mode at 30 degrees /s, 60 degrees /s and 120 degrees /s. All patients underwent a nutritional examination with anthropometric measures, dietary intake survey, biochemical indexes and determination of the medial gastrocnemius volume by magnetic resonance imaging., Results: At T0, whatever the muscle group tested (except at 120 degrees /s for the knee), the MPT appeared significantly lower in the malnourished group. At T1, the increase in MPT (plantar flexors) in malnourished patients was greater at 60 degrees /s (+23.8 %) than at 30 degrees /s (+14.8 %). Correlations between MPT and nutritional parameters were observed in the malnourished group only at T1 and in the normal-nourished group., Conclusion: Isokinetic assessment seems to be a pertinent method to estimate lower limb muscle strength in older and frail subjects. Early modifications in strength were observed in malnourished patients who received oral supplementation and physiotherapy.

Introduction: Lamotrigine is an antiepileptic agent used in a wide range of seizure disorders among the elderly. In rare cases, it can induce a drug hypersensitivity syndrome (DHS)., Cases: DHS due to lamotrigine was observed in two patients (85 and 91 years-old). The first case was characterized by febrile erythema with eosinophilia and the second by isolated fever. Lamotrigine was replaced by sodium valproate for one patient. Both patients had satisfactory outcomes after discontinuing lamotrigine., Discussion: Lamotrigine can induce DHS that is clinically and biologically similar to the DHS observed with standard antiepileptic drugs. It may involve concomitant or consecutive treatment with other antiepileptic agents, in particular, valproate acid, which decreases lamotrigine clearance. Potentially serious and even fatal, these adverse reactions are to be feared in a population with multiple comorbidities and can cause harmful diagnostic mistakes. They are especially fearsome in geriatric populations with high epilepsy rates.

Background: Hyperosmolar syndromes are associated with high mortality rates, yet little is known about their incidence and their prognosis., Objective: To determine the 1-year incidence of hyperosmolar states and the prognostic factors for in-hospital and 1-year mortality., Method: A 6-month prospective cohort study was conducted in a 40-bed acute care geriatric unit and included all patients who developed plasma osmolarity of 320 mosm/l or greater. Age, sex and known cognitive impairment as possible risk factors of hyperosmolarity were assessed. In-hospital and 1-year mortality were calculated and risk factors for death among baseline patient characteristics were sought., Results: 48 (11) of the 436 inpatients in the study were identified as hyperosmolar. Diabetic hyperosmolarity was found in 8 patients. Cognitive impairment was a risk factor for hyperosmolarity (relative risk 2.39, 95% confidence interval 2.18-3.33, p < 0.001), but not age or sex. Infections were accompanied by hyperosmolarity in 30 (62.5). Thirty-five patients (72.9) were bed- or chair-ridden. In-hospital mortality was higher in hyperosmolar patients (35.4) than in the others (16.7%, p = 0.003). Causes of death were infection in 5 (29.4), terminal cachexia in 5, thrombosis in 3, gastric bleeding in 1, renal failure in 2 and heart failure in 1. Functional dependency for mobility was a risk factor for in-hospital mortality but not the degree of hyperosmolarity. One-year mortality was 68.7%. Functional dependency and pressure ulcers were independent predictors of 1-year mortality (p = 0.005 and p = 0.044, respectively)., Conclusion: Hyperosmolar states occurred in cognitively impaired and dependent patients and resulted in high mortality rates at short and at mid-term. Mortality was related to functional dependency rather than to hyperosmolarity., (Copyright 2004 S. Karger AG, Basel)

Introduction: The assessment and treatment of pain in elderly hospitalised patients are essential elements for the management of these patients. Within the context of a policy aimed at fighting against pain, a transversal survey was conducted at the university hospital centre in Bordeaux to enhance knowledge on pain, its impact and the difficulties in its assessment in these elderly patients., Objective: Analyse the data of this survey concerning patients aged 65 and over, hospitalised in various departments of medicine and in the Geriatric centre., Methods: In this "on a given day" transversal survey, 221 patients underwent self-assessment of their pain using a questionnaire and the numerical scale. 365 patients with cognitive or phasic disorders were assessed using a behavioural scale (Doloplus). The prevalence of pain was calculated in the various departments. The type of pain, its impact, its acknowledgment by the nurses and the physicians and the treatments were described., Results: The prevalence of pain was of 47.5% in the patients who underwent self-assessment. In the patients who underwent a hetero-assessment, it was of 63.6% in Medicine and 20% in the Geriatric centre. Acute pain predominated in medicine (49%) and chronic pain in the Geriatric centre (52%). The impact of pain on morale was moderate or severe in 60% of patients, and on sleep in 51%. The simultaneous agreement of the nurses and physicians on the pain felt by the patients was of 32% in Medicine and 44.5% in the Geriatric centre., Conclusion: There is a problem in the acknowledgment of pain in elderly patients. This is related to the systematic non-use of assessment tools and the overlooking of rules for the use of analgesics, particularly in the treatment of chronic pain.

Background: Plasma homocysteine concentrations increase with age and remain an independent risk factor for vascular disease in the elderly. There are negative correlations between plasma homocysteine and serum folate and vitamin B12 concentrations. Two mechanisms, poor nutritional status, and chronic atrophic gastritis, could explain hyperhomocysteinemia., Objective: The purpose of the study was to determine prevalence and mechanisms of hyperhomocysteinemia in older hospitalized patients., Designs: During a 12-month period, all the consecutive hospitalized patients who underwent gastric endoscopy were recruited in this observational prospective study. Clinical, histological, and biological data concerning nutritional status, gastric analysis, homocysteine, vitamin B12, and folate concentrations were collected during the study for each included patient., Results: One hundred and ninety six patients (132 women and 64 men, mean age: 85.3 5.7 years) were included. Hyperhomocysteinemia (>or= 18 mmol/l) was diagnosed in 45.4 %, cobalamin deficiency in 13.3 %, and folate deficiency in 11.7 % patients. Hyperhomocysteinemia was significantly correlated to cobalamin deficiency (r = - 0.21; p = 0.005). In a sub group of patients without hypothyroidism, or chronic renal impairment, univariate and multivariate analysis showed a significant association between hyper homocysteinemia and low MNA (OR: 0.92; 95% CI 0.85-0.99), and low albumin (OR: 0.92; 95% IC: 0.83-0.99; p = 0.04). No correlation was found between homocysteine concentrations and chronic atrophic gastritis or Helicobacter pylori infection., Conclusion: Hyperhomocysteinemia seems to be frequent in the elderly and is associated with poor nutritional status rather than chronic atrophic gastritis.

Comprehensive geriatric assessment is a useful complement to the standard clinical examination of elderly people. It focuses on a systematic evaluation of functional status, dependency, cognitive functions, psychological status, continence, nutritional status and social way of life, administered by a multidisciplinary team. Standardized test, well-validated in the elderly, are used. Most studies have demonstrated the efficacy of geriatric assessment programs in outpatients, hospitalized patients or in emergency unit patients. Mostly useful in frail elderly patients, geriatric assessment results in a decrease in morbidity and dependency, shorter hospital stays and fewer referrals to nursing homes. By introducing adequate medical and social interventions, comprehensive geriatric assessment, even in very old people, is useful in preventing acute situations leading to emergency referrals.

Background: The objectives of the study were to estimate the incidence of readmission one month after discharge, to determine the proportion of planned readmissions and of those avoidable, and to identify risk factors associated with early readmissions in elderly admitted to an acute geriatric unit., Methods: A prospective study was conducted on a sample of 322 patients, 75 years of age or older, discharged from an acute geriatric service. A phone follow-up was realized one month after discharge. A multivariate logistic regression model was used to identify risk factors for readmission., Results: Global incidence of early readmission was 16.2% (that is 50 rehospitalizations), 18.0% of which were planned. Among the 21 readmissions to the same service, five were avoidable according to the Appropriateness Evaluation Protocol. Logistic regression analysis identified three patient characteristics that were independent predictors of early readmission, which were: a need of help for locomotion (OR=4.38, p=0.002), a negative answer to the question "do you feel that your life is empty?" (OR=2.22, p=0.02) and a short length of stay (p<0.02)., Conclusion: A better knowledge of risk factors should allow targeting patients at high risk of early hospital readmission, which should profit by preventive interventions during the first hospitalization. Two domains of possible action were identified in this study: a sufficient length of stay and a better attention to patients with reduced autonomy, especially for those who go back home after discharge.

Objective: Description of the nutritional status of healthy elderly people and investigation of its longitudinal relationship with mortality and cognitive or functional decline., Design: Longitudinal study., Setting: In Dordogne, France., Subjects: A total of 169 French elderly community dwellers aged 68 y and older from in the PAQUID (Personnes Agées QUID) study were included. Dietary intake was assessed by a 3 day food record and a dietary history. Self-reported weight and height were used to calculate the body mass index (BMI, kg/m(2)). Mortality, activities of daily living (ADL), instrumental activities of daily living (IADL) and the Mini Mental State Examination (MMSE) were measured at 5 y follow-up., Results: Nutritional intake and BMI vary according to age and sex. Men generally have a higher nutritional intake than women. Intake decreases with age especially in men. Among the 169 subjects, 22 died. When analyzed by logistic regression, there was no relation between markers of risk of poor nutrition and mortality but a BMI greater or equal 27 at baseline was associated with a increased risk of 5 y mortality (OR=6.27, 95% CI 1.29-30.37) adjusted for sex and age. With regard to cognitive decline, subjects with a BMI greater or equal than 23 kg/m(2) had 3.6 times lower chance of presenting a decline in the subsequent 5 y adjusted by age and sex (OR=0.28, 95%, CI 0.09-0.90). BMI ranging between 23 and 27 was associated with a significantly decreased risk of IADL disability (OR=0.31, 95% CI 0.10-0.93) in multivariate analyses., Conclusion: In apparently healthy elderly people a BMI ranging between 23 and 27 is associated with lower risks of functional and cognitive declines in the subsequent 5 y.

Purpose: Elderly inpatients are particularly exposed to the risk of nosocomial infections, thus the study of their risk factors and consequences is of interest., Methods: Among 1,565 subjects referred to a short-term geriatric unit, patients hospitalised for a year for an acute event and unable to move themselves were followed up for the occurrence of nosocomial infections., Results: Among these 402 immobilised patients (age: 86.3 +/- 7.6 years), 102 nosocomial infections occurred in 91 patients (22.6%), whereas the estimation of the incidence in the total hospitalised population (1,565 subjects, age: 85.1 +/- 6.2 years) was 9.4% (95% confidence interval [CI] 8.3-11.2). Forty-seven point seven percent of nosocomial infections were urinary tract nosocomial infections, 27.5% were lower respiratory nosocomial infections, 9.2% were cutaneous nosocomial infections, 7.3% were septicaemia and 8.2% were of unknown origin. The relative risk (RR) of NI linked to functional dependency for mobility was 5.5 (95% CI: 3.93-7.7, P < 0.001). Other risk factors were: for all nosocomial infections: cancer diagnosis (RR 1.1, 95% CI: 1.1-1.2, P = 0.01); and respectively for urinary tract NI: bladder indwelling (RR 4.8, 95% CI: 2.9-7.7, P < 0.001), pulmonary NI: swallowing disorders (RR 5.4, 95% CI: 2.8-10.5, P < 0.001); and septicaemia: venous catheter (RR 5.4, 95% CI: 1.3-23.3, P = 0.002). NI were associated with an increased length of stay (22.1 +/- 11.7 days in infected patients vs 16.3 +/- 9.5 days in immobilised non-infected subjects, P < 0.001). The mean length of stay for the 1,565 subjects was 10.3 +/- 7.6 days. Death was attributed to nosocomial infections in 13 subjects. In conclusion, functional dependency for mobility, bladder indwelling, venous catheter, swallowing disorders and diagnosis of cancer were risk factors for nosocomial infections in hospitalised elderly subjects in an acutecare setting.

Objectives: to investigate blood markers of oxidative stress, and enzymatic and non-enzymatic antioxidants in normally nourished elderly people with Alzheimer's disease., Design: case-control study., Subjects: twenty patients with Alzheimer's disease and 23 elderly control subjects, living at home, free from disease and not undergoing any treatment known to have a strong influence on blood oxidative stress markers or antioxidant defence systems., Methods: we performed a nutritional evaluation, including anthropometric and biological measures and a 3-day dietary record. We determined concentrations of antioxidant vitamins (alpha-tocopherol, retinol) and malondialdehyde in plasma and erythrocytes. We also measured erythrocyte enzymatic activities of glutathione peroxidase and copper-zinc superoxide dismutase., Results: the two groups were similar in age, body mass index, dietary record and serum albumin concentration. After adjustment for age, sex and cardiovascular co-morbidity, mean plasma concentration of alpha-tocopherol was lower in those with Alzheimer disease than in control subjects (15+/-3.5 mg/l compared with 18.2+/-3.5; P=0.002), as was the mean plasma concentration of retinol (0.54+/-0.2 mg/l vs 0.7+/-0.2; P=0.014). The mean concentration of free plasma malondialdehyde was higher in those with Alzheimer's disease (0.70+/-0.2 mmol/l vs 0.5+/-0.1; P=0.036). In Alzheimer disease patients, free plasma malondialdehyde concentrations were inversely correlated with levels of alpha-tocopherol (P=0.002) and retinol (P=0.025). Erythrocyte levels of vitamins and enzymatic activities were similar in the two groups., Conclusion: lower plasma concentrations of alpha-tocopherol and retinol in normally nourished elderly patients with Alzheimer's disease than in controls could suggest that these antioxidant vitamins had been consumed as a result of excessive production of free radicals.

Background: Metabolic alterations in skeletal muscle associated with malnutrition and the potential reversibility of such alterations during refeeding are not fully understood., Objective: We characterized early changes in muscle during refeeding in malnourished, hospitalized elderly subjects., Design: Muscle function, metabolism, and mass were evaluated in 24 clinically stable patients (11 were malnourished) by using isokinetic plantar flexor torque measurements and nuclear magnetic resonance (NMR) imaging for medial gastrocnemius mass assessment and 31P and 13C NMR spectroscopy for inorganic phosphate (Pi), phosphocreatine, and glycogen quantitation., Results: Malnourished subjects had lower muscle mass (P < 0.02) and tended to have lower strength than did control subjects. In malnourished subjects, muscle strength increased after refeeding (P < 0.01) whereas muscle mass was unchanged. The ratio of Pi to ATP was lower in malnourished than in control subjects (P < 0.001) and increased during refeeding (P < 0.01). The mean ratio of phosphocreatine to ATP was lower in malnourished than in control subjects (P < 0.01) and increased to control values after refeeding. Muscle glycogen showed a scattered distribution for malnourished subjects; the mean value did not differ significantly from that of control subjects, either at baseline or after refeeding., Conclusions: The lower ratio of phosphocreatine to ATP in malnourished subjects could have resulted from either lower total muscle creatine or reduced oxidative capacities. High or normal glycogen associated with a low Pi-to-ATP ratio in malnourished subjects suggested preferential use of lipid over carbohydrate for energy supply, which is known to reduce muscle performance. The data suggest that normalization of muscle metabolite content after refeeding improves muscle strength in malnourished subjects.

Purpose: The real prevalence of Helicobacter pylori (H. pylori) infection is difficult to determine in the elderly because of the frequency of drug intake (antibiotics or anti-secretory drugs). The aim of this study was to evaluate the diagnostic performance of five tests in the elderly., Methods: The study population consisted of consecutive patients undergoing a routine endoscopy between August 1998 and December 1999. We evaluated the diagnostic performance of four tests in all of the included patients: culture and histology of biopsy specimens, serology (ELISA) and urea breath test (13C-UBT). Detection of H. pylori antigens in stool samples (HpSA) was realized in a subgroup. Patients were considered H. pylori + when result for culture was positive or when two tests were positive., Results: One hundred and sixty-seven patients were included in this study (55 men, 112 women; mean age: 85.6 +/- 5.1 years). Only 38 (22.8%) patients were H. pylori+. Test performances showed the following results: serology sensitivity: 90.9% (IC 95%: 75.6-98.1) versus 86.9% (IC 95%: 63.6-96.9) for culture versus 77.8% (IC 95%: 60.8-89.9) for histology and 74.3% (IC 95%: 56.7-87.5) for 13C-UBT. Eighty-nine (53.3%) took antibiotics or anti-secretory drugs, only 13C-UBT performances decreased significantly (sensitivity: 94.4% [72.7-99.8] versus 52.9% [27.8-77]; P < 10(-6)). When gastric or duodenal ulcer were endoscopically diagnosed in older patients, both histology and 13C-UBT could not improve the diagnosis of H. pylori infection. HpSA was realized in 107 patients (sensitivity: 74.1%, specificity: 98.7%). We showed no statistical difference between HpSA performances and drug intake., Conclusion: Diagnostic performances decreased in older patients especially because of drug intake.

PHYSIOLOGICAL AGING: Anatomical and physiological renal changes occur during normal aging in humans. These changes are different from the renal effects of many diseases frequently linked to aging and which require specific diagnosis, prevention and therapy. Renal aging varies from one patient to another or from one population to another. During common aging, anatomical changes are mild and physiological changes mainly affect glomerular filtration rate and water and salt metabolism regulation. IN THE ELDERLY: Glomerular filtration rate decreases slowly in healthy elderly people to reach 80 ml/mn at 80 years without any metabolic consequence. However, in old hospitalized patients, acute renal failure is frequent and occurs mainly during inflammatory or infectious disorders, dehydration or drug combinations enhancing regulation of glomerular filtration. Tubular function changes expose the elderly to increasing risk of dehydration which could be prevented in highly predictable situations such as gastrointestinal symptoms, poorly salted diets or anorexia. Estimation of the creatinine clearance is necessary whenever an acute medical events, mostly infectious diseases, occur in elderly people to adapt drugs doses to renal catabolism.

Atrial natriuretic factor (ANF) is a peptide hormone secreted by the atria in response to increased transmural pressure. This peptide is the first of a series of natriuretic hormones which also includes brain natriuretic peptide (BNP). It is destroyed mainly by an ubiquitous enzyme, neutral endopeptidase (NEP). Its main actions are vasodilatation and natriuresis. It is the main physiological agonist of the renin/angiotensin/aldosterone system. In elderly subjects free of cardiovascular disease, baseline concentrations are higher than in younger subjects. In patients with congestive heart disease (CHD), the level of ANF rises due to permanent increased filling pressures. Both atrial and ventricular secretion increase ANF levels which loose their day/night rhythm. ANF is a risk factor independent of mortality, rhythm disorders and acute heart failure in patients with heart failure. BNP is also raised in CHD. There is an inverse correlation between concentration and severity of left ventricule dysfunction. There has been little work on ANF in elderly subjects with CHD. ANF is elevated in these patients and is an independent risk factor for cardiac decompensation. In addition, in very elderly subjects where the diagnosis of CHD is difficult and echocardiography not always possible, assay of BNP could be an interesting diagnostic tool. Currently work on therapeutic possibilities (administration of exogenous ANF, combinations with NEP inhibitor/conversion enzyme inhibitor, ANF/diuretics) have revealed certain problems (short half life of ANF, transient effects, non-specific activity of NEP). The usefulness of ANF and BNP in heart failure in elderly subjects will undoubtedly lie in its capacity to mark disease severity and as a diagnostic tool, particularly in case of acute dyspnoea.

Studies have revealed a partial deficiency of growth hormone (GH) secretion in the elderly. Aging has a central effect on the GH secretion and probably a peripheral effect on insulin-like growth factor 1 (IGF-1) or somatomedin C through changes in body composition. Simultaneously therapeutic efficiency of recombinant GH was confirmed in adults with GH deficiency. These notions have led to some controlled trials of GH treatment in elderly. Further studies of GH replacement are needed, examining issues such as dosage, tolerance (still inadequate) and efficacy before the widespread use of GH or IGH-F 1 in the elderly is advocated.

In 2 patients with the nephrotic syndrome, unsuspected solid tumors were found. One was a small cell lung carcinoma, accompanied with the syndrome of inappropriate ADH secretion. The other was a cancer of the breast with lymph node and bone metastases. In both, renal biopsy showed minimal change disease without immune complex deposits. There are only 14 other reported cases of paraneoplastic lipoid nephrosis complicating solid tumors. Such cases lead to the discussion on the respective roles of tumor cell gene product(s) inducing proteinuria and of lymphokine secretion by lymphocytes directed against the tumor itself. Cancer should be considered as a possible etiology of the minimal change nephrotic syndrome in the adult.

Rationale: atheromatous stenosis of both renal arteries, or of the artery of a functionally solitary kidney is a frequent cause of renal failure in the elderly. Atheromatous Ischemic Renal Insufficiency (AIRI) can be ameliorated by surgery or angioplasty. However, such procedures can be hazardous in a patient with extensive aortic atheromatous plaques. This justified a study of the validity of Pulsed Doppler (PD), a diagnostic procedure less invasive than renal angiography in AIRI., Objectives: to evaluate the diagnostic interest of PD in AIRI, using renal angiography as a criterion of adequacy., Methods: renal arteries PD (Ultramak-4, 3.5 and 5 Mhz probes) followed by renal angiography (Seldinger). "Significant" stenosis = 50% on angiography. "Positive" PD = turbulences and/or acceleration., Patients: 32 patients were investigated for suspected AIRI on the grounds of 1) age greater than 50; 2) atheromatous background and 3) renal insufficiency with no other evident etiology, or rapidly declining GFR in such a patient treated with ACE inhibitors., Results: 16/32 angiographies disclosed significant stenosis of at least 1 renal artery. 56 renal arteries were investigated with both angio. and PD. Prevalence of stenoses was 16/56. PD had 93.7% sensitivity and 55% specificity. Positive predictive value was 45.5% and negative predictive value was 95.7%. Specificity was 80% when PD disclosed acceleration., Conclusions: negative PD is sufficient argument to reconsider the indication of renal angiography in a high risk pt with suspected AIRI.

We present here a glomerulonephritis in a patient with dermatomyositis, Sjögren's syndrome and Hashimoto's thyroiditis. Glomerulonephritides are rarely described in dermatomyositis and Sjögren's syndrome. Glomerular histology is variable. Nephrotic syndrome and renal failure are not frequent. Moderate doses of corticosteroids produce a rapid improvement.

We report on a case of tuberous sclerosis in a 36-year-old female with chronic renal failure, who was treated by hemodialysis and transplantation. The diagnosis of tuberous sclerosis was ascertained by the association of typical cutaneous retinal and osseous lesions. On the contrary, the renal localisations were unusual. Early hypertension was exacerbated in the course of 2 pregnancies but was never severe. It preceded the late onset of renal failure which progressed slowly. The kidneys were small, with a peculiar angiographic aspect: the renal tissue was not invaded by hamartomas but the whole arterial bed was diffusely modified, with a cortical perfusion defect. Both kidneys were studied after bilateral nephrectomy. The lesions were far more complex than a simple replacement of the renal tissue by angiomyolipomas: they involved the vessels, the interstitium (with lipids inclusions surrounded by a macrophagic reaction) and the glomeruli (with focal and segmental sclerosis). This observation (which is the 11th case in the literature of tuberous sclerosis with chronic renal failure and the 3rd treated by transplantation) documents a particular variety of congenital and familial nephropathy with delayed revelation.
