[Tardive dyskinesia following discontinuation of neuroleptic therapy in 87-year-old patient]. / Dyskinésies tardives et neuroleptiques chez une patiente de 87 ans.

In the absence of a therapeutic alternative, the use of neuroleptics in geriatrics should be limited to the bare minimum, given their potentially serious deleterious effects in frail elderly patients. Dyskinesia is one of their most common side effects. Case of an elderly patient in whom the dyskinesia was revealed following abrupt cessation of a neuroleptic taken in the long term with discussions of the etiological hypotheses of this rare situation, which nevertheless deserve to be known.

[Strokes and Giant cell arteritis: imaging characteristics]. / AVC et Horton : caractéristiques de l'imagerie.

Giant cell arteritis (GCA) is associated with an increased risk of cardio- or cerebro-vascular death. The stroke rate in patients with GCA varies between 2.7 and 7.4%. The etiological diagnosis may be challenging between atherosclerotic stroke and stroke related to GCA. Case of an old woman who had ischemic stroke and concomitant diagnosis of GCA and brain imaging characteristics.

Exposure to psychotropics in the French older population living with dementia: a nationwide population-based study.

BACKGROUND: Little is known about the level of psychotropic chronic exposure in all patients living with dementia. The aim of the study was to quantify chronic psychotropic exposure in older adults with dementia compared with the general population of the same age. METHODS: This prospective cohort study was conducted in France between 2009 and 2011. Aged at least 65 years, 10,781,812 individuals (440,215 of them with dementia) either community based or nursing home residents were included. The numbers of single or combined prescriptions, per year for antipsychotics, antidepressants, anxiolytics, or hypnotics were measured. RESULTS: Of patients with dementia, 15.5% are exposed to antipsychotics compared with 2.2% of the age-matched population (relative risk [RR] = 6.44, 95% confidence interval [CI] [6.39-6.48]), 39.5% to antidepressants compared with 12.6% (RR = 4.10, 95% CI [.4.07-4.12]), and 39.6% to anxiolytics or hypnotics compared with 26.9% (RR = 1.74, 95% CI [1.72-1.75]). Among older adults with dementia, 13.8% simultaneously consumed at least three psychotropics. All class age of older patients with dementia is more exposed to all psychotropics except for long-acting benzodiazepines. During the study period, chronic anxiolytic/hypnotic and antipsychotic exposure slightly decreased in population with dementia while chronic exposure to antidepressant drugs tended to increase. CONCLUSION: This nationwide, population-based, drug-used study showed for the first time that older patients with dementia are chronically overexposed not only to antipsychotics but also to psychotropics.

Biomarkers of vascular dysfunction and cognitive decline in patients with Alzheimer's disease: no evidence for association in elderly subjects.

BACKGROUND: Several studies have suggested that vascular dysfunction plays an important role in Alzheimer's disease. AIMS: We hypothesized that significant differences might be observed in the levels of blood endothelial biomarkers across elderly population of subjects with dementia. METHODS: We analyzed, in a prospective monocentric study, three different endothelial biomarkers, endothelial microparticles (EMPs), endothelial progenitor cells (EPCs) and circulating endothelial cells (CECs) in 132 older patients who underwent a full evaluation of a memory complaint. RESULTS: There was no difference in specific EMP, EPC or CEC levels between demented or non-demented patients, nor considering cognitive decline. DISCUSSION: Blood endothelial biomarkers may be too sensitive and it is likely that the multimorbidity observed in our patients may lead to opposite and confounding effects on endothelial biomarkers levels. CONCLUSION: Unlike younger AD patients, our results suggest that endothelial biomarkers are not valuable for the diagnosis of dementia in elderly patients.

Atypical Presentation of Bacteremia in Older Patients Is a Risk Factor for Death.

BACKGROUND: The absence of fever in bacteremia in patients who are older is known to delay diagnosis. Our objective was to determine whether atypical presentation was associated to mortality as a result of bacteremia in this patient cohort as well as possible factors associated with this atypical presentation. METHODS: We conducted an observational prospective study in 2 French university hospitals in 2016-2017 including patients ages ≥75 years with bacteremia. Atypical presentation was defined as the absence of a temperature ≥38.3°C or <36°C, chills, or hypotension. Mortality and dependence for activities of daily living (ADL) were recorded at 1 week (D7) and 3 months (D90). RESULTS: Among the 151 patients (mean age 85.4±5.8 years) enrolled, atypical presentation prevalence was 21.2%. D7 and D90 mortality rates were 7.9% and 40.0%, respectively. Atypical presentation was independently associated with D7 (odds ratio (OR) 4.46, 95% confidence interval (CI) 1.04-19.24) and D90 mortality (OR 3.76, 95% CI 1.30-10.92) after controlling for other prognostic factors. Patients with diabetes and those infected with Staphylococcus aureus were more likely to have atypical signs of infection. ADL score decreased from 3.6±2.0 before bacteremia to 2.8±2.1 at D90 (P <0.001). CONCLUSION: Patients who are older with bacteremia have poor vital and functional prognoses in the short and long terms. The absence of typical signs of infection is associated with mortality. Blood culture should be considered for patients who are older, especially with diabetes with acute unexplained clinical manifestations.

Determinants of clinical presentation on outcomes in older patients with myocardial infarction.

AIM: Myocardial infarction without chest pain misleads the clinician, resulting in a diagnosis delay and an increase of mortality. The main objective of the present study was to determine the risk factors of atypical presentation in older patients with myocardial infarction. METHODS: All consecutive patients aged ≥75 years presenting with myocardial infarction and hospitalized in the cardiology intensive care unit were included in the present prospective multicenter observational study. All patients benefited from both specialized cardiac management and geriatric assessment. RESULTS: A total of 215 consecutive patients were included. The mean age was 85 ± 6 years. A total of 142 patients (66%) had a typical presentation (i.e. chest pain) and 73 patients (34%) had an atypical clinical presentation (i.e. no chest pain). A total of 29 (13.5%) patients died within 30 days of the index hospitalization. Higher Cumulative Illness Rating Score-Geriatric severity index score (P = 0.019) and initial atrial fibrillation (P = 0.022) were predictive of 30-day all-cause mortality. Typical presentation (P = 0.010) was a protective factor of 30-day all-cause mortality. A Cumulative Illness Rating Score for Geriatrics total score increase (P = 0.0003) and residing in a nursing home (P = 0.024) emerged as independent risk factors for atypical presentation. CONCLUSIONS: In "real-life" elderly patients, comorbidities influence the prognosis of myocardial infarction, but also clinical presentation. Identification of patients at risk of atypical presentation; that is, patients with multiple comorbid conditions, might help refine the prognostic value in older patients with myocardial infarction.

Determinants of invasive strategy in elderly patients with non-ST elevation myocardial infarction.

BACKGROUND: Knowledge gaps across literature prevent current guidelines from providing the profile of elderly patients most likely to derive benefit from invasive strategy (IS) in non ST-elevation myocardial infarction (NSTEMI). Furthermore, the benefit of IS in a real-world elderly population with NSTEMI remains unclear. The aims of this study were to determine factors that lead the cardiologist to opt for an IS in elderly patients with NSTEMI, and to assess the impact of IS on the 6-month all-cause mortality. METHODS: This multicenter prospective study enrolled all consecutive patients aged ≥ 75 years old who presented a NSTEMI and were hospitalized in cardiology intensive care unit between February 2014 and February 2015. Patients were compared on the basis of reperfusion strategy (invasive or conservative) and living status at six months, in order to determine multivariate predictors of the realization of an IS and multivariate predictors of 6-month mortality. RESULTS: A total of 141 patients were included; 87 (62%) underwent an IS. The strongest independent determinants of IS were younger age [odds ratio (OR): 0.85, 95%-confidence interval (CI): 0.78-0.92; P < 0.001) and lower "Cumulative Illness Rating Scale-Geriatric" number of categories score (OR: 0.83, 95%CI: 0.73-0.95; P = 0.002). IS was not significantly associated with 6-month survival (OR: 0.80, 95%CI: 0.27-2.38; P = 0.69). CONCLUSIONS: In real-world elderly patients with NSTEMI, younger patients with fewer comorbidities profited more often from an IS. However, IS did not modify 6-month all-cause mortality.

Isolated cardiac troponin rise does not modify the prognosis in elderly patients with hip fracture.

Perioperative myocardial infarction remains a life-threatening complication in noncardiac surgery and even an isolated troponin rise (ITR) is associated with significant mortality. Our aim was to assess the prognostic value of ITR in elderly patients with hip fracture.In this cohort study, all patients admitted between 2009 and 2013 in our dedicated geriatric postoperative unit after hip fracture surgery with a cardiac troponin I determination were included and divided into Control, ITR, and acute coronary syndrome (ACS) groups. The primary end point was a composite criteria defined as 6-month mortality and/or re-hospitalization. Secondary end points included 30-day mortality, 6-month mortality, and 6-month functional outcome.Three hundred twelve patients were (age 85 ±â€Š7 years) divided into Control (n = 217), ITR (n = 50), and ACS (n = 45) groups. There was no significant difference for any postoperative complications between ITR and Control groups. In contrast, atrial fibrillation, acute heart failure, hemorrhage, and ICU admission were significantly more frequent in the ACS group. Compared to the Control group, 6-month mortality and/or rehospitalization was not significantly modified in the ITR group (26% vs. 28%, P = 0.84, 95% confidence interval [CI] of the difference -13%-14%), whereas it was increased in the ACS group (44% vs. 28%, P = 0.02, 95% CI of the difference 2%-32%). ITR was not associated with a higher risk of new institutionalization or impaired walking ability at 6 months, in contrast to ACS group.In elderly patients with hip fracture, ITR was not associated with a significant increase in death and/or rehospitalization within 6 months.

[Link between non hypoxemic chronic obstructive pulmonary disease and executive functioning in oldest old]. / Étude du lien entre la broncho-pneumopathie obstructive non hypoxémiante et le fonctionnement exécutif de patients de plus de 75 ans.

COPD (chronic obstructive pulmonary disease) may result in cognitive disorders (mainly executive) even without hypoxemia. The aim of this descriptive study was to highlight a deficit in task-switching in non-hypoxemic patient with COPD and mild cognitive impairment (MCI) or Alzheimer disease (AD). The main judgment criterion was patients' performances on the TMTA and B. COPD patients were recruited via the database (CogDisCo) of the geriatric medicine department at Pitié Salpêtrière hospital in Paris. 7 patients had Alzheimer's disease (AD), and 11 mild cognitive impairment (MCI): they were matched for age, sex, MMSE, education level with controls subjects without COPD. There was no significant difference between the two groups. However, patients with COPD and MCI required, on average, an extra 13 seconds compared with patient without COPD for the TMTA and 18 seconds for the TMTB. Patients with COPD and AD needed, on average, an extra 63 seconds for TMTA and 97 seconds for TMTB. The number of errors for the TMTB was the same in the both groups. This preliminary study does not show statistically significant results but the time for achieving TMT was longer in the population with COPD whether AD or MCI. These results encourage us to continue with prospective studies on larger samples.

[Analysis of 736 blood transfusions in a geriatric teaching hospital]. / Seuils et objectifs transfusionnels chez des patients de plus de 75ans : analyse de 736 transfusions de culots globulaires et comparaison aux recommandations.

BACKGROUND: Red blood cell transfusion in elderly patients with anemia requires taking into account a hemoglobin threshold, as well as comorbidities that may be decompensated by anemia. In the absence of consensual indications for blood transfusion in the elderly population, it seems important to evaluate the practical approach of blood transfusion in geriatrics. We analyzed prescriptions of red blood cell transfusion in very old patients hospitalized in a geriatric teaching hospital. METHODS: This retrospective study was based on information collected during one year in 736 red blood cell transfusion prescriptions. Hemoglobin levels, numbers of red blood cell units and clinical informations notified by prescribing physicians have been collected and analyzed. RESULTS: The mean hemoglobin level before red blood cell transfusion was 8.45±0.94g/dL. Two variables were significantly associated with an increase of the transfusion threshold above 9g/dL: the poor tolerance of anemia (P<10(-4)) and clinical situations at risk for poor tolerance of anemia (P=0.0076). The most frequent symptoms of poor tolerance of anemia were cardiovascular symptoms and also acute neuropsychiatric symptoms that could be considered as specific criteria for the red cell transfusion in the elderly. The mean number of red blood cell units prescribed for each transfusion was 1.88±0.55 and the only predictive factor was the hemoglobin level (P<0.001). PERSPECTIVES: In our geriatric practice, transfusion thresholds and target hemoglobin levels after transfusion seemed to be comparable with the thresholds recommended in the only available French guidelines edited in 2002 by the Afssaps. However, our study pointed out specific geriatric particularities in red blood cell transfusion prescriptions with the use of some tolerance criteria that seem related to non-cardiovascular comorbidities. Future prospective interventional studies could be conducted in order to evaluate the clinical relevance of these potential specific geriatric criteria in transfusion indications.

Persistent high nevirapine blood level with DRESS syndrome 12 days after interruption of antiretroviral therapy.

Nevirapine is an antiretroviral agent associated with drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. Such a case in an immunocompetent woman recently treated with nevirapine for postexposure HIV prophylaxis is reported here. Despite a period of 12 days after interruption of treatment, a high blood level of nevirapine was still observed.
