EpistemisClinical fragility
Specialty: Geriatrics.
Why it occurs
- Advanced sarcopenia associated with senile neuroendocrine deregulation (decrease in growth hormone, IGF-1, testosterone and DHEA-S)
- Low-grade chronic systemic inflammation ("inflammaging") mediated by elevation of proinflammatory cytokines such as IL-6 and TNF-alpha
- Subclinical protein-calorie malnutrition and chronic micronutrient deficiencies (especially Vitamin D and vitamin B12)
- Mitochondrial dysfunction and accumulation of oxidative stress at the cellular level that limits muscle energy production
- High burden of accumulated comorbidity (chronic kidney disease, heart failure, severe generalized osteoarthritis)
Initial workup
Formal evaluation of the frailty phenotype using the Fried Criteria (grip strength measured with a dynamometer, 4-meter walking speed, weight loss, physical activity level assessed by the Minnesota questionnaire, and self-perceived fatigue) or the FRAIL scale; blood analysis that includes complete blood count, albumin, prealbumin, high-sensitive C-reactive protein, thyroid profile (TSH, free T4), serum levels of 25-hydroxyvitamin D, vitamin B12 and folic acid; bone densitometry if suspicion of osteoporosis coexists.
red flags
Involuntary weight loss of more than 5% in the last six months associated with a state of extreme exhaustion reported by the patient, repeated falls that acutely compromise independence for basic self-care, repeated episodes of delirium due to minor stressors (such as room changes or mild infections), or absolute inability to get up from a chair without the help of the arms.
Standard management
- Cholecalciferol — Vitamin D3, 1000 IU to 2000 IU orally daily, indicated to improve skeletal muscle contraction force and bone density in patients with 25(OH)D levels less than 30 ng/ml
- High protein and high calorie enteral nutritional supplementation — rich in essential amino acids, leucine and beta-hydroxy-beta-methylbutyrate [HMB], recommended after sessions of guided strength-resistance physical exercise
- Active and structured deprescription of drugs on the Beers list that do not have a clear indication to reduce polypharmacy and the risk of interactions.
