Long COVID burden and risk factors in 10 UK longitudinal studies and electronic health records

Abstract:

The frequency of, and risk factors for, long COVID are unclear among community-based individuals with a history of COVID-19. To elucidate the burden and possible causes of long COVID in the community, we coordinated analyses of survey data from 6907 individuals with self-reported COVID-19 from 10 UK longitudinal study (LS) samples and 1.1 million individuals with COVID-19 diagnostic codes in electronic healthcare records (EHR) collected by spring 2021. Proportions of presumed COVID-19 cases in LS reporting any symptoms for 12+ weeks ranged from 7.8% and 17% (with 1.2 to 4.8% reporting debilitating symptoms). Increasing age, female sex, white ethnicity, poor pre-pandemic general and mental health, overweight/obesity, and asthma were associated with prolonged symptoms in both LS and EHR data, but findings for other factors, such as cardio-metabolic parameters, were inconclusive.

Long COVID: systemic inflammation and obesity as therapeutic targets

Management of the post-COVID-19 condition—often referred to as long COVID—is a challenge for health-care professionals because of the heterogeneity and complexity of its clinical manifestations and the probable need for multidisciplinary management approaches. Identification and understanding of modifiable determinants associated with manifestations of long COVID would help in the adaptation of treatment pathways for particular phenotypes. In The Lancet Respiratory Medicine, the PHOSP-COVID Collaborative Group report the latest results from the UK-based, multicentre, prospective Post-hospitalisation COVID-19 (PHOSP-COVID) study, in which the investigators identified systemic inflammation and obesity as factors that might be associated with long COVID, representing potentially treatable traits in people with more severe post-COVID-19 symptoms.

In the current report, the PHOSP-COVID Collaborative Group found increased levels of several biomarkers related to systemic inflammation and lung damage in individuals with more severe physical and mental health impairments 1 year after hospital discharge. The presence of increased levels of systemic inflammatory biomarkers (eg, cytokines) in individuals with severe acute COVID-19 has been reported previously. Moreover, the use of anti-inflammatory agents such as corticosteroids or interleukin-6 (IL-6)-blocking agents has been found to be associated with positive outcomes in patients hospitalised with acute COVID-19.

Obesity and lipid metabolism disorders determine the risk for development of long COVID syndrome: a cross-sectional study from 50,402 COVID-19 patients

Abstract:

Purpose: Metabolic disorders have been identified as major risk factors for severe acute courses of COVID-19. With decreasing numbers of infections in many countries, the long COVID syndrome (LCS) represents the next major challenge in pandemic management, warranting the precise definition of risk factors for LCS development.

Methods: We identified 50,402 COVID-19 patients in the Disease Analyzer database (IQVIA) featuring data from 1056 general practices in Germany. Multivariate logistic regression analysis was used to identify risk factors for the development of LCS.

Results: Of the 50,402 COVID-19 patients included into this analysis, 1,708 (3.4%) were diagnosed with LCS. In a multivariate regression analysis, we identified lipid metabolism disorders (OR 1.46, 95% CI 1.28-1.65, p < 0.001) and obesity (OR 1.25, 95% CI 1.08-1.44, p = 0.003) as strong risk factors for the development of LCS. Besides these metabolic factors, patients’ age between 46 and 60 years (compared to age ≤ 30, (OR 1.81 95% CI 1.54-2.13, p < 0.001), female sex (OR 1.33, 95% CI 1.20-1.47, p < 0.001) as well as pre-existing asthma (OR 1.67, 95% CI 1.39-2.00, p < 0.001) and depression (OR 1.27, 95% CI 1.09-1.47, p = < 0.002) in women, and cancer (OR 1.4, 95% CI 1.09-1.95, p = < 0.012) in men were associated with an increased likelihood of developing LCS.

Conclusion: Lipid metabolism disorders and obesity represent age-independent risk factors for the development of LCS, suggesting that metabolic alterations determine the risk for unfavorable disease courses along all phases of COVID-19.

Severity of COVID-19: Causes and Consequences — From Obesity to Chronic Fatigue Syndrome

Introduction:

In circumstances of COVID-19 epidemiological uncertainty, the causes and consequences of the disease remain important issues.

The aim of this study was to investigate obesity as a potential predisposition and chronic fatigue syndrome (CFS) as a possible consequence of COVID-19.

The study was conducted in two parts: a theoretical part, in which a literature review was performed, and an empirical part, in which COVID-19 patient survey data were analysed. To identify the main findings regarding the relationship between obesity and COVID-19, the literature review was focused on the investigation of systematic reviews and meta-analyses by three databases – Medline(via  PubMed),  Cochrane  COVID-19  Study  Register,  and  PROSPERO  (International prospective register of systematic reviews).

The patient survey was performed to investigate the relationship between obesity and severity of the disease, as well as the presence of CFS symptoms in COVID-19 patients in Latvia.

The main findings of the literature review showed that obesity increases the risk of hospitalisation, disease severity, clinical complications, poor outcomes, and mortality. The results of the patient survey showed that overweight and obesity were more critical factors for men (males) suffering with COVID-19 than for women (females) in Latvia.

The patient group with obesity caused almost half of all hospitalisations. The research data assumed that CFS  patients  were  not  a  high-risk  group  for  COVID-19,  but  COVID-19  caused  CFS-like symptoms in patients and potentially increased the number of undiagnosed patients.

In the context of further epidemiological uncertainty and the possibility of severe post-viral consequences, preventive measures are becoming increasingly important.

Obesity in adolescents with chronic fatigue syndrome: an observational study

Abstract:

OBJECTIVE: Identify the prevalence of obesity in patients with chronic fatigue syndrome (CFS) compared with healthy adolescents, and those identified with CFS in a population cohort.

DESIGN: Cross-sectional analysis of multiple imputed data.

SETTING: Data from UK paediatric CFS/myalgic encephalomyelitis (CFS/ME) services compared with data collected at two time points in the Avon Longitudinal Study of Parents and Children (ALSPAC).

PATIENTS: 1685 adolescents who attended a CFS/ME specialist service between 2004 and 2014 and 13 978 adolescents aged approximately 13 years and 16 years participating in the ALSPAC study.

MAIN OUTCOME MEASURES: Body mass index (BMI) (kg/m2), sex-specific and age-specific BMI Z-scores (relative to the International Obesity Task Force cut-offs) and prevalence of obesity (%).

RESULTS: Adolescents who had attended specialist CFS/ME services had a higher prevalence of obesity (age 13 years: 9.28%; age 16 years: 16.43%) compared with both adolescents classified as CFS/ME in ALSPAC (age 13 years: 3.72%; age 16 years: 5.46%) and those non-CFS in ALSPAC (age 13 years: 4.18%; age 16 years: 4.46%). The increased odds of obesity in those who attended specialist services (relative to non-CFS in ALSPAC) was apparent at both 13 years (OR: 2.31 (1.54 to 3.48)) and 16 years, with a greater likelihood observed at 16 years (OR: 4.07 (2.04 to 8.11)).

CONCLUSIONS: We observed an increased prevalence of obesity in adolescents who were affected severely enough to be referred to a specialist CFS/ME service. Further longitudinal research is required in order to identify the temporal relationship between the two conditions.

Examining the impact of obesity on individuals with chronic fatigue syndrome

Abstract:

Chronic fatigue syndrome (CFS) is a complex disorder affecting multiple body systems. The most commonly used definition of CFS is 6 or more months of fatigue and the presence of at least four of eight minor symptoms. In addition, many health and psychological conditions, including severe obesity-body mass index (BMI) of 40 kg/m(2) or greater-exclude individuals from a diagnosis of CFS. Obesity has been correlated with fatigue, sleep problems, and less satisfaction with general health, functioning, and vitality.

The current study investigated weight trends over time in a community-based sample of individuals with CFS and healthy controls. The study further investigated the impact of comorbid weight issues on several health and disability outcomes in a subset of overweight individuals.

Overweight and obese individuals with CFS demonstrated poorer functioning than controls who were similarly weighted. One participant was excluded because she had gained weight at a monitoring visit and her BMI was greater than 40 kg/m(2). The implications of these findings for health care workers are discussed.
