Inflammatory markers in geriatric anemia: A study from North India

Background

Inflammation has several effects in the geriatrics with reference to iron deficiency anemia (IDA), anemia of chronic disease (ACD), and unexplained anemia (UA). Whether hyperinflammation is part of their pathogenesis or just incidental is unknown. Data are limited regarding inflammatory patterns in IDA, ACD, and UA in anemic geriatrics and inflammation as a component of UA. There is little known about the overlap of inflammation between ACD and UA.

Objective

The study was undertaken to find the proportion of anemic geriatric patients, aged ≥60 years with raised serum levels of inflammatory markers and their study within IDA, ACD, and UA.

Materials and Methods

Seventy-five anemic geriatric patients were evaluated for raised serum levels of inflammatory markers: high sensitive C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) along with serum ferritin (SF).

Results

Raised markers were seen in 94.7% of anemic geriatric patients.IL-8 was raised most frequently followed by TNF-α, IL-6, hsCRP, and SF. No distinct inflammatory profile could be elicited between ACD and UA. The hyperinflammatory profile irrespective of the underlying etiology of geriatric anemia suggests that aging per se is pro-inflammatory state.

Conclusion

Geriatric anemia can be thought to develop on background of subclinical low-grade inflammation along with superimposed nutritional deficiencies or chronic diseases.

[Profiling of patients in a specialized geriatric outpatient clinic]

BACKGROUND

In Germany geriatric outpatient care is predominantly done by family doctors and general practitioners (GP). There are regionally different concepts for additional specialized geriatric outpatient care but they have not yet been validated and established. Still, it remains unclear whether a geriatric patient has to be diagnosed rather in a specialized outpatient or inpatient setting. The aim of the present study is the profiling of geriatric outpatients to find key distinctions from geriatric patients that have to be admitted to hospital.

METHODS

Retrospective data analysis of patients sent to a specialized geriatric outpatient clinic by their GP, compared with data of geriatric inpatients sent to hospital by their GP during the same time period. Study parameters comprised elements of the comprehensive geriatric assessment as well as results of routinely applied laboratory tests.

RESULTS

Patients sent to the specialized geriatric outpatient clinic showed better results of functional assessments. Regression analysis: improvement of Barthel Index, GFR and total protein increased the chance of outpatient treatment.

CONCLUSION

Early identification of geriatric patients who can be treated in a specialized outpatient setting would ease the burden for GPs by interdisciplinary cooperation and prevent cost-intensive readmissions to hospital.

Anemia in Elderly Patients-The Impact of Hemoglobin Cut-Off Levels on Geriatric Domains

Background: The primary aim of this study was to evaluate the impact of anemia—according to the WHO criteria—on cognitive performances, mood, functional and nutritional status, and comorbidities in a population of subjects aged 65 years or older. The secondary aim of this study was to understand if different hemoglobin cut-off levels are associated with a variation of the mentioned domains’ impairment. Methods: We designed a cross-sectional study, including subjects aged 65 or more consecutively evaluated in an outpatient setting from July 2013 to December 2019. A sum of 1698 subjects met the inclusion criteria. They were evaluated with: MMSE and CDT (cognitive assessment), GDS (mood), BADL, IADL, PPT, and POMA (autonomies), MNA (nutritional status), and CIRS (comorbidities). Results: According to the WHO criteria, non-anemic patients reported significantly better performances than the anemics in BADL (p < 0.0001), IADL (p = 0.0007), PPT (p = 0.0278), POMA (p = 0.0235), MNA, CIRS TOT, CIRS ICC, and CIRS ISC (p < 0.0001). The same tendency has been found by considering the 12 g/dL- and the 13 g/dL-cut-off level in the whole population. The multivariate analysis showed that, considering the 12 g/dL-cut-off level, age (OR: 1.03, p = 0.0072), CIRS (OR: 1.08, p < 0.0001), and gender (OR: 0.57, p = 0.0007) were significant regressors of anemia, while considering the 13 g/dL-cut-off level, age (OR: 1.04, p = 0.0001), POMA (OR: 1.03, p = 0.0172), MNA (OR = 0.95, p = 0.0036), CIRS (OR: 1.17, p < 0.0001), ICC (OR = 0.83, p = 0.018), and gender (OR = 0.48, p < 0.0001) were significant regressors of anemia, while the other CGA variables were excluded by the model (p > 0.01). Conclusions: Our study showed that anemia negatively impact on geriatric people’s general status, regardless of which hemoglobin cut-off level is considered. It also highlighted that hemoglobin concentrations < 13 g/dL, regardless of gender, have an association with the impairment of the affective-functional-nutritional state as well as an increase in comorbidities; therefore, it should be pursuable to consider the elderly person “anemic” if Hb < 13 g/dL regardless of gender.

The clinical implications and importance of anemia in older women

OBJECTIVES

The objective of this study was to investigate associations between anemia with geriatric syndromes and comprehensive geriatric assessment (CGA) parameters in older women.

METHODS

886 older outpatient women were included. Anemia was defined as a hemoglobin concentration below 12 g/dL. patients were divided into two groups as anemic and non-anemic. The relationships between anemia and CGA parameters/geriatric syndromes were determined.

RESULTS

The mean age of the participants was 76.00 ± 8.91. The prevalence of patients with anemia was 15.35%. There was a significant difference between anemic and non-anemic groups in terms of age, Charlson Comorbidity Index, body mass index, the number of drugs used, and the presence of chronic renal failure (p < 0.05). After adjustment for these covariates, anemia was associated with Timed Up and Go test (OR: 1.10, 95% CI: 1.02-1.18), muscle strength (OR: 0.99, 95% CI: 0.83-0.99), dynapenia (OR: 1.92, 95% CI: 1.06-3.47), Mini Nutritional Assessment scores (OR: 0.88, 95% CI: 0.83-0.94), poor nutritional status (OR: 1.97, 95% CI: 1.10-3.48), Fried scores (OR: 1.42, 95% CI: 1.24-1.68), frailty (OR: 2.58, 95% CI: 1.42-4.69), falls (OR: 1.78, 95% CI: 1.10-2.92) and polypharmacy (OR: 2.31, 95% CI: 1.38-3.86).

CONCLUSION

In the present study anemia was associated with frailty, polypharmacy, poor nutritional status, falls, and decreased muscle strength. Therefore, anemia may be a sign of poor health status in older women. When anemia is detected in an older woman, CGA should be strongly considered if not routinely performed.

The prevalence of anemia and its associations with other geriatric syndromes in subjects over 65 years old: data of Russian epidemiological study EVKALIPT

Background. A low hemoglobin level in older adults impairs cognitive ability and functional status and associates with risk of falls and fractures, sarcopenia, malnutrition, depression, frailty, and decreased autonomy. Epidemiological data on the anemia prevalence in the geriatric population in our country is not available. Aim. To assess the prevalence of anemia and analyze its associations with geriatric syndromes (GS) in subjects aged 65 years. Materials and methods. 4308 subjects (30% of men) aged 65107 years, living in 11 regions of the Russian Federation, were examined and divided into age groups (6574 years, 7584 years and 85 years). All the participants underwent a comprehensive geriatric assessment and determined hemoglobin level. Results. The anemia prevalence in older adults was 23.9%. It has been shown that with an increase in age per 1 year, the risk of anemia detection increases by 4%. The incidence of anemia was higher in males than females (28.1% versus 22.1%; p0.001). In most cases, anemia was mild. The results of a comprehensive geriatric assessment show that patients with anemia had lower hand grip force, Barthel Index, the sum of points on Lawton instrumental activities of daily living scale, Mini Nutritional Assessment scale, the Mini-Cog test and higher the sum of points on the Geriatric Depression Scale (GDS-15) and the Age Is No Barrier scale. Patients with anemia were more likely to use hearing aids, absorbent underwear, and assistive devices during movement. Patients with anemia had a higher incidence of all GS, except for orthostatic hypotension and chronic pain syndrome. The presence of GS is associated with an increased risk of anemia by 1.33.4 times. Conclusion. EVKALIPT study obtained domestic data on the prevalence of anemia in older patients and examined its associations with other GS.

Molecular Aspects and Treatment of Iron Deficiency in the Elderly

Iron deficiency (ID) is the most frequent nutritional deficiency in the whole population worldwide, and the second most common cause of anemia in the elderly. The prevalence of anemia is expecting to rise shortly, because of an ageing population. Even though WHO criteria define anemia as a hemoglobin serum concentration <12 g/dL in women and <13 g/dL in men, several authors propose different and specific cut-off values for the elderly. Anemia in aged subjects impacts health and quality of life, and it is associated with several negative outcomes, such as longer time of hospitalization and a higher risk of disability. Furthermore, it is an independent risk factor of increased morbidity and mortality. Even though iron deficiency anemia is a common disorder in older adults, it should be not considered as a normal ageing consequence, but a sign of underlying dysfunction. Relating to the molecular mechanism in Iron Deficiency Anemia (IDA), hepcidin has a key role in iron homeostasis. It downregulates the iron exporter ferroportin, inhibiting both iron absorption and release. IDA is frequently dependent on blood loss, especially caused by gastrointestinal lesions. Thus, a diagnostic algorithm for IDA should include invasive investigation such as endoscopic procedures. The treatment choice is influenced by the severity of anemia, underlying conditions, comorbidities, and the clinical state of the patient. Correction of anemia and iron supplementation should be associated with the treatment of the causal disease.

Prevalence and Causes of Anemia in Hospitalized Patients: Impact on Diseases Outcome

Anemia is extremely common in hospitalized patients who are old and often with multiple diseases. We evaluated 435 consecutive patients admitted in the internal medicine department of a hub hospital and 191 (43.9%) of them were anemic. Demographic, historic and clinical data, laboratory tests, duration of hospitalization, re-admission at 30 days and death were recorded. Patients were stratified by age (<65, 65-80, >80 years), anemia severity, and etiology of anemia. The causes of anemia were: iron deficiency in 28 patients, vitamin B12 and folic acid deficiencies in 6, chronic inflammatory diseases in 80, chronic kidney disease in 15, and multifactorial in 62. The severity of the clinical picture at admission was significantly worse (p < 0.001), length of hospitalization was longer (p < 0.001) and inversely correlated to the Hb concentration, re-admissions and deaths were more frequent (p 0.017) in anemic compared to non-anemic patients. A specific treatment for anemia was used in 99 patients (36.6%) (transfusions, erythropoietin, iron, vitamin B12 and/or folic acid). Anemia (and/or its treatment) was red in the discharge letter only 54 patients. Even if anemia is common, in internal medicine departments scarce attention is paid to it, as it is generally considered a "minor" problem, particularly in older patients often affected by multiple pathologies. Our data indicate the need of renewed medical attention to anemia, as it may positively affect the outcome of several concurrent medical conditions and the multidimensional loss of function in older hospitalized patients.

[Perioperative patient blood management in the aged-more than only transfusion? : Review of the 4th symposium of the working group on anemia on the occasion of the annual meeting of the German Geriatric Society in Frankfurt 2019]

Anemia is frequent in older people with one in two geriatric inpatients being affected. Therefore, in elective surgery, such as endoprosthetic treatment it is very likely that anemia is already present in a preoperative setting. So far there are no particular guidelines about perioperative management of anemia in geriatric patients. The existing recommendations of the Patient Blood Management (PBM) network cooperation and the current Association of the Scientific Medical Societies in Germany (AWMF) S3 guidelines on preoperative anemia refer to all patients aged >18 years but without particular consideration of the growing number of oldest old orthogeriatric patients. This is more problematic as anemia in the aged has been shown to be different from anemia in younger patients in terms of diagnostics and treatment. Based on several interdisciplinary lectures, this year the symposium of the working group on anemia of the German Geriatric Society (DGG) focused on the problems of perioperative PBM in orthogeriatric patients and encouraged the discussion about developing PBM treatment recommendations for this patient group.

[The geriatric syndrome of anemia-Summary of the symposium of the working group anemia during the annual meeting of the German Geriatric Society 2018 in Cologne, Germany]

This year's symposium of the working group anemia of the German Geriatric Society (DGG) aimed to underline the multicausality of anemia in the aged and to highlight definition parallels with geriatric syndromes. For these reasons, nutritional and malignant causes for anemia were discussed and the influence of oxidative stress on the development of anemia was underlined. The need for ongoing research in the field of anemia in the aged was emphasized by the lack of perioperative transfusion strategies in geriatric patients.
