“Living like an empty gas tank with a leak”: Mixed methods study on post-acute sequelae of COVID-19

Abstract:

Background: The burden and presentation of post-acute sequela of SARS-CoV-2 infection (PASC) are a developing major public health concern.

Objectives: To characterize the burden of PASC in community-dwelling individuals and understand the experiences of people living with PASC.

Methods: This mixed-methods study of COVID-19 positive community-dwelling persons involved surveys and in-depth interviews. Main outcome was self-report of possible PASC symptoms 3 weeks or longer after positive COVID-19 test. In-depth interviews were guided by a semi-structured interview guide with open-ended questions and probes based on emerging literature on PASC and the impact of COVID-19.

Results: With a survey response rate of 70%, 442 participants were included in this analysis, mean (SD) age 45.4 (16.2) years, 71% female, 12% Black/African American. Compared to those with no PASC symptoms, persons who reported PASC symptoms were more likely to be older (mean age: 46.5 vs. 42; p = 0.013), female (74.3% vs. 61.2%; p = 0.010), to have pre-existing conditions (49.6% vs. 34%; p = 0.005), and to have been hospitalized for COVID-19 (14.2% vs. 2.9%; p = 0.002). About 30% of the participants experienced severe fatigue; the proportion of persons reporting severe fatigue was 7-fold greater in those with PASC symptoms (Adjusted Prevalence Ratio [aPR] 6.73, 95%CI: 2.80-16.18). Persons with PASC symptoms were more likely to report poor quality of life (16% vs. 5%, p<0.001) and worse mental health functioning (Mean difference: -1.87 95%CI: -2.38, -1.37, p<0.001). Themes from in-depth interviews revealed PASC was experienced as debilitating.

Conclusions: In this study, the prevalence of PASC among community-dwelling adults was substantial. Participants reported considerable coping difficulties, restrictions in everyday activities, invisibility of symptoms and experiences, and impediments to getting and receiving PASC care.

Risk factors, health outcomes, healthcare services utilization, and direct medical costs of long COVID patient

Abstract:

Background: Data on the economic burden of long-COVID are scarce. We aimed to examine the prevalence and medical-costs for treating long-COVID.

Methods: We conducted this historical-cohort study using data of patients with COVID-19 among members of a large health-provider in Israel. Cases were defined according to physician diagnosis (definite long-COVID) or suggestive symptoms given ≥4-weeks from infection (probable cases). Healthcare resource utilization (HCRU) and direct healthcare costs (HCCs) in the period prior to infection and afterwards were compared across study groups.

Findings: Between March 2020, and March 2021, a total of 180,759 COVID-19 patients (mean[SD] age=32.9y [19.0y]; 89,665 [49.6%] females) were identified. Overall, 14,088(7.8%) individuals developed long-COVID (mean[SD] age=40.0y [19.0y]; 52.4% females). Among them, 1,477(10.5%) were definite long-COVID and 12,611(89.5%) were defined as probable long-COVID. Long-COVID was associated with age (AOR=1.058 per year, 95%CI:1.053-1.063), female sex (AOR=1.138;1.098-1.180), smoking (AOR=1.532;1.358-1.727), and symptomatic acute-phase (AOR=1.178;1.133-1.224), primarily muscle-pain and cough. Hypertension was an important risk factor for long-COVID among younger adults. Compared to non-long-COVID patients, definite and probable cases were associated with AORs of 2.47(2.22-2.75) and 1.76(1.68-1.84) for post-COVID hospitalization, respectively. While among non-long COVID patients HCCs decreased from US$ 1400 during 4 months before the infection to US$ 1021, among long-COVID patients HCC increased from $US 2435 to $US 2810.

Interpretation: Long-COVID is associated with a substantial increase in healthcare services utilization and direct-medical costs. Our findings underline the need for timely planning and allocating resources for long-COVID patient-centered care as well as for its secondary-prevention in high-risk patients.

A comparison of health-related factors between patients diagnosed with ME/CFS and patients with a related symptom picture but no ME/CFS diagnosis: a cross-sectional exploratory study

Abstract:

Background: In chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS), the capacity for activity and participation is strongly limited. The disease definition is very broad, and considering the lack of evidence for best treatment, it is important to understand what is ME/CFS-specific in the biopsychosocial perspective in comparison with similar syndromes. The objective was to study the difference between those diagnosed with ME/CFS and those with similar symptoms but no ME/CFS diagnosis for self-perceived level of physical activity, work ability, anxiety/depression, and health-related quality of life.

Methods: This was a clinical cross-sectional study with data collected from mailed questionnaires. The following variables were compared between patients diagnosed with ME/CFS (n = 205) and those with similar symptoms but no diagnosis (n = 57); level of physical activity, Work ability index (WAI), Hospital anxiety and depression scale (HAD-A/HAD-D), and RAND-36 Physical functioning, Role limitations due to physical health problems, Role limitations due to personal or emotional problems, Social functioning, Energy/fatigue, Bodily pain, Emotional well-being, and General health perceptions. The Chi-squared test (nominal data), the Mann-Whitney U test, the Student’s t test and regression analysis were used to analyze the data.

Results: The group diagnosed with ME/CFS had a more impaired physical and mental exertion ability as compared to the group that had similar symptoms but was not diagnosed with ME/CFS, shown by a RAND-36 lower index of physical role functioning, social functioning, energy, worse pain and poorer overall health (p ≤ 0.05). In contrast, no significant group differences emerged for weekly level of physical activity, work ability, anxiety/depression, and RAND-36 Emotional role limitation and well-being.

Conclusion: Our results indicate that those with a diagnosis of ME/CFS are characterized by an impaired ability for physical or mental exertion, worse pain, and poorer overall health as compared to individuals with similar symptoms but for whom ME/CFS-diagnosis was not established. The results may be cautiously interpreted as support when focusing on patients’ self-care in terms of management of energy levels. The results must however be verified in future studies.

Association between long COVID symptoms and employment status

Abstract:

Background: Symptoms of Coronavirus-19 (COVID-19) infection persist beyond 2 months in a subset of individuals, a phenomenon referred to as long COVID, but little is known about its functional correlates and in particular the relevance of neurocognitive symptoms.

Method: We analyzed a previously-reported cohort derived from 8 waves of a nonprobability-sample internet survey called the COVID States Project, conducted every 4-8 weeks between February 2021 and July 2022. Primary analyses examined associations between long COVID and lack of full employment or unemployment, adjusted for age, sex, race and ethnicity, education, urbanicity, and region, using multiple logistic regression with interlocking survey weights.

Results: The cohort included 15,307 survey respondents ages 18-69 with test-confirmed COVID-19 at least 2 months prior, of whom 2,236 (14.6%) reported long COVID symptoms, including 1,027/2,236 (45.9%) reporting either ‘brain fog’ or impaired memory. Overall, 1,418/15,307 (9.3%) reported being unemployed, including 276/2,236 (12.3%) of those with long COVID and 1,142/13,071 (8.7%) of those without; 8,228 (53.8%) worked full-time, including 1,017 (45.5%) of those with long COVID and 7,211 (55.2%) without. In survey-weighted regression models, presence of long COVID was associated with being unemployed (crude OR 1.44, 95% CI 1.20-1.72; adjusted OR 1.23, 95% CI 1.02-1.48), and with lower likelihood of working full-time (crude OR 0.73, 95% CI 0.64-0.82; adjusted OR 0.79, 95% CI 0.70 -0.90). Among individuals with long COVID, the presence of cognitive symptoms — either brain fog or impaired memory — was associated with lower likelihood of working full time (crude OR 0.71, 95% CI 0.57-0.89, adjusted OR 0.77, 95% CI 0.61-0.97).

Conclusion: Long COVID was associated with a greater likelihood of unemployment and lesser likelihood of working full time in adjusted models. Presence of cognitive symptoms was associated with diminished likelihood of working full time. These results underscore the importance of developing strategies to respond to long COVID, and particularly the associated neurocognitive symptoms.

Beyond COVID-19 and SARS-CoV-2, cardiovascular outcomes of “long covid” from a pathological perspective – a look back and road ahead

Abstract:

With the decrease in severity of COVID-19 there is a sense of relief in the general population. However, there has been an increased incidence of cardiovascular and other organ complications post-infection, which have raised concerns about long COVID. The term “long COVID” was first used by Perego on social media to denote the persistence of symptoms weeks or months after initial SARS-CoV-2 infection and the term ‘long haulers’ was first described by Watson and by Yong to identify post-COVID conditions.

There has been an increased incidence of sudden cardiac death and MI post-COVID-19 in healthy individuals, sports persons and prominent movie stars. Potential mechanisms contributing to the pathophysiology of post-acute COVID-19 may include 1) Damage to tissues and cells that are important for blood flow, so clotting of blood is increased. 2) Persistence of fragments of virus or its sub-particles/ protein material in a wide range of body sites and, 3) an immune system gone haywire.

As the majority of countries across the globe are easing coronavirus precautionary measures, there is an urgent need by health care organizations and policymakers worldwide to generate awareness by educating the public at large, about the ill effects of long-COVID and varied types of post-acute sequelae of COVID-19.

Understanding the experiences of caring for a partner with myalgic encephalopathy: a qualitative study of men in Norway

Abstract:

Background: Informal caring is expanding in many countries as populations age. There is a lot of research on how to care responsibilities are experienced by next of kin, but there is little research on men, which is the focus of this study. This specific focus is Myalgic Encephalopathy (ME), which is a condition that often affects women. This means that it is men who often find themselves in a caring role.

Aim: This project aims to explore what it was like for Norwegian men to have a caring role toward a partner with ME and how it affects everyday life.

Method: A qualitative approach was used. Ten semi-structured interviews were conducted, and the participants were recruited from different places in Norway. All were between the ages of 30 to 60 years old and were caring for a partner for several years. To analyze the data, thematic analysis was used, to find different patterns in the data.

Results: A data emerged two main themes and seven under the themes “experiencing the impact of caring for a partner with ME on everyday life “and providing different kinds of support. The experience around the role of caring was influenced by several factors, such as changes in finances and family dynamics as well as accessing formal support. Overall, the mean men felt that being in a caring role meant that life was being put on hold.

Conclusion: Findings from this study help to strengthen previous research. Having a caring role for a sick partner with ME was demanding and greatly affects everyday life. Men found the role of care challenging and it could negatively affect the person psychologically. For most people in a caring role, there was potential for better support both emotionally and financially.

Unpaid carers are the missing piece in treatment guidelines and research priorities for ME/CFS

Dear Editor,

The recent publication of a new NICE Guideline1 , an All-Party Parliamentary Group Report (APPG)2, and new Research Priorities3 heralds a dramatic shift in approaches and attitudes to Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS) in the UK. Largely ignored in all three publications, however, are unpaid carers (known outside the UK as family carers or caregivers). The vast majority of people with ME/CFS rely on their families for care and many of those families have been the driving force behind the changes to research and treatment
that are now unfolding.

There has been limited research on unpaid care in the specific context of ME/CFS, but the few existing studies clearly show that the usual toll of caring for a sick or disabled family member is compounded by the historic prejudice surrounding ME/CFS and the absence of evidence-based treatments.g.4-7.

While we applaud the commitment of NICE, the APPG, and the Priority Setting Partnership, it may still be decades before biomedical breakthroughs are made or translated into effective, widely available treatments for ME/CFS8. In the meantime, families will continue to provide the majority of
care for people with ME/CFS and bear the physical, psychological, and economic scars of doing so.

The new NICE guideline does recommend support for carers, but the supports it recommends are generic. They will do little to address the unique needs of ME/CFS carers or their systemic mistreatment by health and social care professionals. A change in the UK’s approach to ME/CFS is long overdue, but without a focus on unpaid carers the puzzle will always be missing a piece. The wellbeing of carers must also be a priority in ME/CFS
research and effective strategies must be developed to address their needs, and recognise and respect their expertise, in clinical practice and social care.

The prevalence of SARS-CoV-2 infection and long COVID in US adults during the BA.5 surge, June-July 2022

Abstract:

Due to changes in SARS-CoV-2 testing practices, passive case-based surveillance may be an increasingly unreliable indicator for monitoring the burden of SARS-CoV-2, especially during surges. We conducted a cross-sectional survey of a population-representative sample of 3,042 U.S. adults between June 30 and July 2, 2022, during the Omicron BA.5 surge. Respondents were asked about SARS-CoV-2 testing and outcomes, COVID-like symptoms, contact with cases, and experience with prolonged COVID-19 symptoms following prior infection.

We estimated the weighted age and sex-standardized SARS-CoV-2 prevalence, during the 14-day period preceding the interview. We estimated age and gender adjusted prevalence ratios (aPR) for current SARS-CoV-2 infection using a log-binomial regression model.

An estimated 17.3% (95% CI 14.9, 19.8) of respondents had SARS-CoV-2 infection during the two-week study period, equating to 44 million cases as compared to 1.8 million per the CDC during the same time period. SARS-CoV-2 prevalence was higher among those 18-24 years old (aPR 2.2, 95% CI 1.8, 2.7) and among non-Hispanic Black (aPR 1.7, 95% CI 1.4 ,2.2) and Hispanic (aPR 2.4, 95% CI 2.0 , 2.9). SARS-CoV-2 prevalence was also higher among those with lower income (aPR 1.9, 95% CI 1.5, 2.3), lower education (aPR 3.7 95% CI 3.0,4.7), and those with comorbidities (aPR 1.6, 95% CI 1.4, 2.0). An estimated 21.5% (95% CI 18.2, 24.7) of respondents with a SARS-CoV-2 infection more than 4 weeks prior reported long COVID symptoms.

The inequitable distribution of SARS-CoV-2 prevalence during the BA.5 surge will likely drive inequities in the future burden of long COVID.

Inequity and disparities mar existing global research evidence on Long COVID

Abstract:

Since the pandemic began in December 2019, SARS-Cov2 has accentuated the wide gap and disparities in socioeconomic and healthcare access at individual, community, country, and regional levels. More than two years into the current pandemic, up to three-fourths of the patients are reporting continued signs and symptoms beyond the acute phase of COVID-19, and Long COVID portends to be a major challenge in the future ahead.

With a comprehensive overview of the literature, we found that most studies concerning long COVID came from high and upper-middle income countries, and people of low-income and lower-and-middle income regions and vulnerable groups with comorbid conditions have been neglected. Apart from the level of income, there is a significant geographical heterogeneity in investigating the Post-Acute Sequelae of COVID-19 (PASC) or what we call now, long COVID. We believe that these recognizing health disparities is crucial from equity perspective and is the first step toward global health promotion.

Exposure-response relationship between K. brevis blooms and reporting of upper respiratory and neurotoxin-associated symptoms

Abstract:

In southwest Florida, Karenia brevis (K. brevis) blooms occur frequently, can be very intense and persist over several years. Individuals living in coastal communities around the Gulf of Mexico are particularly vulnerable to brevetoxins released by K. brevis in seawater and carried inland within marine aerosol. Exposure to K. brevis occurs during residential, recreational, and occupational activities and has been associated with upper respiratory tract (URT) symptoms in healthy and medically vulnerable individuals. Additionally, ingestion of brevetoxin-contaminated seafood causes neurotoxic shellfish poisoning (NSP), and severe headaches prompting emergency department visits which occur in excess during K. brevis blooms.

The current study examined a dose-response relationship between K. brevis in coastal waters and URT and NSP-like symptoms and headaches among southwest Florida residents. Data on past medical history (PMH) and medical symptoms were collected from the participants (n = 258) in five southwest Florida counties between June 2019 to August 2021. A dose-response relationship was observed between K. brevis blooms and reporting of URT and NSP-like symptoms and headaches. Reporting of NSP-like symptoms was higher among participants with a PMH of migraines, chronic fatigue syndrome (CFS) and mild memory loss, while the association of headaches with K. brevis blooms was accentuated among individuals with a PMH of migraines.

These results suggest further investigations into the threshold of aerosolized brevetoxin dose required to elicit URT, headaches and/or NSP-like symptoms. These symptoms ultimately cause significant public health safety concerns, primarily among vulnerable populations with preexisting neurological conditions.
