[Medication reconciliation: Interests and limits]. / Conciliation médicamenteuse : intérêts et limites.

Admission to hospital is a critical transition point for the continuity of care in medication management. Medication reconciliation can identify and resolve errors due to inaccurate medication histories. The practice of medication reconciliation is securing for the patient because of the medication errors detected with significant clinical impact. Its implementation must comply with the recommendations of the French National Authority for Health (HAS) and its deployment is now integrated into the contract for improving the quality and efficiency of care (CAQES). However, although it allows to intercept medication errors, its impact on the length of hospitalization, the rate of readmission and/or death following discharge seems limited. Given the limited human resources to carry out this time-consuming activity, patient prioritization should be considered. Studies on the fate of patients and on the medico-economic issues are also necessary in order to make this activity sustainable.

Identification of Frailty in a Population of Former Immigrant Workers in the South of France.

BACKGROUND: Frailty is unevenly distributed across the world but also within different populations in the same country. OBJECTIVES: This study sought to identify frailty in former immigrant workers, known as Chibanis, living in an immigrant hostel in Marseille. The secondary objective was to describe health care access, as well as any chronic diseases reported. DESIGN, PARTICIPANTS AND SETTING: Our descriptive, observational, monocentric study conducted from January to April 2021 included 67 Chibanis, living in an immigrant hostel in Marseille. MEASUREMENTS AND RESULTS: Almost all this population (97%), with a median age of 77 years, presented at least one frailty criterion: 7.5% were malnourished, 55.2% had a grip strength of < 27 kg, and 41.8% were on multiple drugs. Majority of Chibanis (86.6%) had multimorbidity. CONCLUSION: Identifying frailty in this population of Chibanis must be proposed through a specific, adapted care pathway including referral to a specialist.

HoSAGE: Sarcopenia in Older Patients before and after Treatment with Androgen Deprivation Therapy and Radiotherapy for Prostate Cancer.

BACKGROUND: Sarcopenia is a muscle disease defined by a loss of muscle strength associated to a decrease in skeletal muscle mass. In addition to aging, many factors may contribute to sarcopenia as cancer and/or androgen deprivation therapy (ADT). OBJECTIVES: The aims of this study are to describe the prevalence of sarcopenia in older prostate cancer patients before initiation of treatment with ADT and radiotherapy, and to evaluate the impact of ADT on the occurrence or aggravation of sarcopenia in this population. DESIGN: longitudinal study. PARTICIPANTS AND SETTING: Sarcopenia was prospectively evaluated in 31 consecutive patients aged 70 to 88 years, referred in one hospital unit of south eastern France, for a comprehensive geriatric assessment (CGA) before cancer treatment initiation. MEASUREMENTS AND RESULTS: CGA, measures of muscle strength and physical performances were performed at baseline (T0) and at the end of cancer treatment (T1). Appendicular skeletal muscle mass was measured by Dual-energy X-ray absorptiometry (DXA) at the end of treatment. At T0, 8 patients (among 31) had a probable sarcopenia according to European consensus, and 18 had altered physical performance. At T1, 15 patients (among 19) had abnormal one leg balance test. Finally, only one patient had a sarcopenia confirmed by DXA. CONCLUSION: This preliminary study showed a high prevalence of muscle disorders before initiation of ADT in a population of elderly cancer prostate patients with intermediate frailty status, and an increased risk of falls at the end of ADT. This highlighted the importance of screening for sarcopenia before treatment initiation, to prevent the occurrence or aggravation of sarcopenia by possible adjustment of treatment, and implementation of appropriate exercise and nutrition interventions.

Adherence to fracture liaison service programs in patients over 70: the hidden part of the iceberg.

Significant dropout rates have been observed throughout Fracture Liaison Service (FLS) programs, especially for elderly patients. In an FLS program set up specifically for patients over 70, the non-initiation of osteoporosis treatment was the only factor associated with poor adherence to the program. Neither age nor frailty factors affected adherence. INTRODUCTION: FLS programs are considered the most effective interventions for secondary prevention of osteoporotic fractures. Our objective was to identify risk factors for non-adherence to an FLS program set up specifically for patients over 70. METHODS: Our multifaceted, intensive program included five appointments over a 2-year period. One hundred sixty-seven patients (mean age 83.5 years) who presented with a recent fragility fracture were enrolled. Multivariable analysis was conducted to determine whether the demographic, clinical, frailty, and osteoporotic risk factors of the patients influenced their adherence to the program. RESULTS: About half of the patients did not attend the follow-up visits. According to the regression analysis, non-initiation of osteoporosis treatment was associated with poor adherence to the program (aHR 3.66). Demographic, clinical, dwelling, frailty factors, osteoporotic risk factors, fracture type, or densitometric scores were not associated with adherence. The first self-reported reason for withdrawal was the difficulty of attending several follow-up visits, and the second was the feeling of not being concerned. CONCLUSION: We observed that non-initiation of osteoporosis treatment was the only factor correlated with non-adherence to an FLS program. Thus, neither age nor frailty factors should result in patients not being included in FLS. Beyond the necessity of the osteoporosis treatment, good patient understanding of the relevance of all the interventions included in the program is the key.

Cyclophosphamide dose adjustment based on body weight and albuminemia in elderly patients treated with R-mini-CHOP.

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in elderly patients, and R-CHOP chemotherapy is the standard treatment protocol for DLBCL. Elderly patients (often defined as 75 years of age) are treated with anticancer drugs with precaution; however, the pharmacokinetics and pharmacodynamics (PK and PD) of these agents have not been thoroughly investigated in this population. In this study, we investigated the PK of cyclophosphamide (CP) and doxorubicin (DOXO) in elderly patients in order to verify if there is an influence of age on the PK of these anticancer drugs. MATERIALS AND METHODS: This is a prospective multi-center clinical trial investigating the PK of CP and DOXO in elderly and very elderly patients with DLBCL treated by R-mini-CHOP regimen. Dose levels were 25 mg/m2, 0.7-1.4 mg/m2, 750 mg/m2, and 375 mg/m2 for DOXO, Vincristine (VCR), CP, and Rituximab, respectively. For PK analysis, 7 time point samples were collected over 48 h post-administration on cycle 3. CP and VCR plasma concentrations were measured using UPLC-MS/MS validated method. DOX plasma concentrations were measured using UPLC coupled with fluorescence detection-validated method. PK-POP modeling has been performed with a non-linear mixed-effect model program (Monolix). RESULTS: 31 patients (15 males and 16 females), 75 to 96 years old, were treated with R-miniCHOP protocol. Among them, 19 patients were treated with VCR. A one-compartment (1cpt) open model with linear elimination adequately described CP concentration-time courses. The population PK parameters for CP were: CL = 3.58 L/h, Vmale = 32.2 L, and Vfemale = 28.7 L. Body weight (BW), albuminemia, and gender demonstrated a significant impact on CP PK. A 2-compartment (2cpt) open model with linear elimination best described DOXO concentration-time courses. The population PK parameters for DOXO obtained for the structural model were: CL = 51.1 L/h, Q = 49.6 L/h, V1 = 29.4 L, V2 = 1,130 L (clearances: CL, Q, volumes of distribution: V1, V2). The main covariate effects on DOXO PK were related to gender, BW, and VCR administration. VCR increases DOXO V1 from 29.4 L to 57.5 L (p = 0.02). No hematologic and cardiac grade 3 or 4 toxicity were recorded. CONCLUSIONS: Usually, in the absence of specific data, the majority of the physicians empirically reduce anticancer drug dose in the elderly patients (Tourani in J Geriatr Oncol 3(1): 41-48, 2012), or even does not treat these very-old patients. A better knowledge of the pharmacokinetics in very-old patients should allow a better dose adjustment based on the most significant physiological factors that modify the pharmacokinetic parameters. In this study, no serious toxicity was observed in these very elderly patients (84.1 years). This indicates that dose adjustment of chemotherapies should not only be based on age and creatinine clearance, but also, based upon appropriate physiological and biological data. Our findings indicate that, CP dose adjustment should be done according to serum albumin levels and patients BW and gender.

Cobalamin deficiency in the elderly: aetiology and management: a study of 125 patients in a geriatric hospital.

INTRODUCTION: Cobalamin deficiency is frequent in elderly patients and the main aetiologies are food-cobalamin malabsorption and pernicious anaemia. The aim of our retrospective study was to identify the causes and methods of management of cobalamin deficiency at Nice geriatric university hospital. METHODS: A retrospective monocentric study was conducted over 14 months at Nice geriatric hospital, which included patients with cobalamin deficiency having received supplementation. The clinical and paraclinical data, etiological diagnosis, treatment and follow-up modalities were analyzed retrospectively. RESULTS: We studied 125 elderly patients whose median age was 85.5 ± 7 years. The etiological diagnosis was food-cobalamin malabsorption for 72 patients (57.6 %), nutritional cobalamin deficiency for 15 patients (12 %), pernicious anaemia for 12 patients (9.6 %) and there was no etiological diagnosis for 26 patients (20.8 %). Concerning cobalamin therapy, 111 patients (88.8 %) received oral therapy and 14 (11.2 %) intramuscular therapy. Vitamin B12 levels increased significantly after supplementation (p<0.001) but cobalamin administration varied according to the diagnoses (p<0.001) and was less effective in patients with dementia (p=0.04) and food-cobalamin malabsorption. CONCLUSION: Our study showed the importance of food-cobalamin malabsorption in etiological diagnosis in accordance with the literature, but also the non-negligible share of nutritional cobalamin deficiency. Mainly oral cobalamin supplementation was used in our study with a significant increase in vitamin B12 levels. An oral cobalamin regimen is proposed for elderly patients with cobalamin deficiency but with no severe neurological signs.

[Is pure red cell aplasia a new extra digestive manifestation of celiac disease?]. / L'érythroblastopénie: nouvelle manifestation extradigestive de la maladie coeliaque?

INTRODUCTION: Celiac disease is an autoimmune enteropathy that appears on a predisposed genetic background. Its clinical presentation has been extended those last years by varied extradigestive manifestations. EXEGESIS: This is a case report of a twenty-year-old woman who presented simultaneously a celiac disease and pure red cell aplasia. The IgA and IgG antigliadin antibodies as well as antinuclear, anti-DNA, anti-SSA and anti-SSB antibodies were detected, without any clinical symptom supporting the diagnosis of systemic lupus erythematosus or Sjögren syndrome. Thoracic CT-scan reveals a thymus enlargement and biopsy concludes to thymus hyperplasia at histological examination. Pure red cell aplasia regressed after gluten-free diet, corticoid therapy and thymectomy. CONCLUSION: This observation, added to the three others paediatric cases previously published in the literature concern an uncommon association between pure red cell aplasia and celiac disease. However, they are not enough to conclude to a direct link between these two disorders. Pure red cell aplasia could represent un new dysimmune manifestation occurring in celiac disease, but this will need to be confirmed with others cases.
