RESUMO

BACKGROUND: Older subjects with chronic kidney disease (CKD) are often affected by multiple geriatric impairments that may benefit from a comprehensive geriatric assessment (CGA). However, ordinary execution of CGA in all these individuals would be unaffordable. We evaluated if Frailty Phenotype (FP) could identify older CKD-patients that may benefit the most from a CGA. METHODS: We evaluated 112 CKD patients not yet on dialysis (age ≥ 65 years, eGFR < 45 ml/min). FP was defined according to the criteria proposed by Fried and co-authors. CGA evaluated four domains (nutrition, physical performance, cognition and depression). Malnutrition was defined in accordance to Malnutrition-Inflammation Score (MIS) and/or by the presence of Protein Energy Wasting syndrome (PEW). Physical performance was evaluated using Short Physical Performance Battery (SPPB) and handgrip strength. Cognitive status was assessed by using Mini Mental State Examination (MMSE) and Clock Drawing Test. Mood was investigated with Geriatric Depression Scale (GDS). RESULTS: Average age of our cohort was 80 ± 6 years and mean eGFR 24 ± 11 ml/min/1.73 m2. Prevalence of frailty was 45%. Frail patients (F-CKD) had higher prevalence of malnutrition (58 vs 29%, p = 0.0005), physical impairment (100% vs 78%; p < 0.0001), cognitive dysfunction (83% vs 37%; p < 0.0001) and depression (50% vs 21%; p < 0.001) compared to robust ones (NF-CKD). Moreover, F-CKD patients had higher probability to have > 2 impaired domains (83% sensitivity and 76% specificity) respect to NF-CKD individuals. CONCLUSIONS: FP is a reliable screening tool to identify older CKD-patients that may benefit from a CGA.

RESUMO

PURPOSE: Hyponatremia and hypokalemia are common among elderly and have been associated with osteoporosis, we evaluate the role of these electrolytes as risk for fragility fractures. METHODS: This study is divided in two parts: one retrospective and one prospective. We retrospectively collected data on urgently admitted patients for femoral fragility fractures (Fx) or for acute myocardial infarction (AMI), and patients admitted for elective hip/knee replacement surgery for osteoarthrosis (OA). Age, sex, serum sodium, potassium, creatinine, and comorbidities were recorded. We enrolled prospectively in-patients from our unit: age, sex, comorbidities, drugs, and fragility fractures were recorded. Blood electrolytes were measured. Cognitive function, nutrition, muscular strength, and balance were evaluated by standard tests. The mortality rate was recorded with a follow-up after hospital discharge. RESULTS: The retrospective study included 2166 subjects: 702 Fx and 1464 controls (907 AMI, 557 OA): the prevalence of hyponatremia was similar in Fx and AMI, whereas it was higher in Fx with respect to OA (p < 0.001) as well as hypokalemia (p < 0.001). Sodium decrease was associated with higher fracture risk. Among the 284 subjects included in the prospective study, 50 patients were hyponatremic, more likely malnourished, and presented a higher prevalence of fragility fractures (p = 0.008). They had a higher mortality after hospital discharge (HR = 1.80, p = 0.005), however, this association disappears after correction for confounding variables. CONCLUSIONS: We suggest that hyponatremia and hypokalemia have to be considered as a marker of poor health more than an independent fracture risk.

RESUMO

OBJECTIVE: Chronic kidney disease (CKD) is a disabling condition associated with different medical comorbidities including depression and cognitive impairment. We investigated the association between malnutrition, inflammation and depressive/cognitive symptoms in elderly subjects with advanced CKD. METHODS: We evaluated cross-sectionally 132 elderly subjects (age ≥65 years) with advanced CKD (stage 4-5, non-dialytic-ND) in regular follow up at the outpatient clinic of nephrology. Blood and urinary samples were collected after an overnight fast. All patients were evaluated by Geriatric Depression Scale (GDS)-30 items for severity of depressive symptoms, Mini Mental State Examination (MMSE) and the Clock Drawing Test (CDT) for cognition. Nutritional status was assessed by Malnutrition Inflammation Score (MIS). Different linear regression models were performed to study the association between clinical variables, diet and inflammatory parameters with the above mentioned rating scale scores. A final linear regression model with only previous statistically significant variables was performed for GDS scores. RESULTS: Our cohort consisted of 95 males and 37 females with a mean age of 78 ±â€¯7. Female gender (B = 3.20, p < .01), higher MIS (B = 0.29, p = .02) and higher IL-12p70 serum levels (pg/mL) (B = 0.37, p = .03) were associated with severity of depressive symptoms. MIS was associated with the severity of cognitive impairment as assessed by MMSE (B = -0.19, p < .01) and CDT (B = 0.10, p = .03). CONCLUSION: In elderly subjects affected by CKD the severity of depressive symptoms and cognitive impairment is associated with specific inflammatory and nutritional parameters. These results have to be considered as preliminary and need replication by further studies.
