Post COVID-19 Syndrome in Patients with Asymptomatic/Mild Form

Abstract:

Post COVID-19 Syndrome (PCS) is a complex of various symptoms developing a month or more after the acute phase of the disease. The cases of PCS development among patients with asymptomatic/mild forms are frequently reported; however, the pathogenesis of PCS in this group of patients is still not completely clear. The publications about COVID-19 which were published in online databases from December 2019 to September 2021 are analyzed in this review. According to the analysis, PCS develops on average in 30-60% of patients, mainly among women. Fatigue, shortness of breath, cough, and anosmia were reported as the most common symptoms. The possible association between the described PCS symptoms and brain damage was revealed.

We assume the possibility of an alternative course of COVID-19, which develops in genetically predisposed individuals with a stronger immune response, in which it predominantly affects the cells of the nervous system, possibly with the presence of an autoimmune component, which might have similarity with chronic fatigue syndrome or autoimmune disautonomia. Thus, the gender (female) and the presence of anosmia during an asymptomatic or mild course of the disease can be predictive factors for the development of PCS, which can be caused by autoimmune damage to neurons, glia, and cerebral vessels.

Addressing the Long COVID Crisis: Integrative Health and Long COVID

Abstract:

While COVID-19 has killed millions of people globally, its lasting effects on the health and well-being of entire populations are just becoming clear. As many as 30% of those diagnosed with COVID-19 report continuing health-related problems, regardless of the severity of the initial infection. Given the infection rate in the world, that translates to between 5.4 and 17.9 million globally; about 700 000 in the US. The syndrome goes by many names; here we call it “long COVID.” Patients experience a wide range of symptoms, including serious organ system effects such as pulmonary fibrosis, myocarditis, new diabetes diagnoses, stroke, and other cerebrovascular events. They also experience ongoing pain, fatigue, and cognitive dysfunction. We suggest here that these patients require an integrative health approach, one that combines traditional medical management, non-pharmacological approaches, and behavior and lifestyle changes. Such an approach has been shown to be beneficial in other chronic illnesses such as fibromyalgia, chronic fatigue syndrome, and post-Lyme disease.

Missteps in Creating a Long Haul COVID Case Definition

Excerpt:

Millions of individuals who have not recovered from the COVID virus are now dealing with a host of symptoms that are challenging our health care system. Many are experiencing significant problems in being recognized by health care workers as a real disorder, as for many of them, there are no biological markers of persistent illness. Just as with ME/CFS, we need to be sure that long haul COVID patients are not victimized first by the pandemic and then by the health care skepticism of their significant symptoms. We have the conceptual and theoretical grounding to develop clinical and research case definitions for those with persisting COVID symptoms. Patients must be instrumentally involved in all such efforts as failure to do so will only further delegitimize their condition.

Post-COVID syndrome: the aftershock of SARS-CoV-2

Introduction:

Significant time has passed since the coronavirus disease of 2019 (COVID-19) pandemic outbreak, which led to severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection in hundreds of millions of individuals all around the globe. Accumulation evidence along the pandemic raised an association between the SARS-CoV-2 and autoimmunity (1). SARS-CoV-2 infected patients have a high presence of various autoantibodies (1). Moreover, numerous cases of new-onset of autoimmune-related disorders had been documented following the infection, including both organ-specific and systemic autoimmune diseases (1).

Recent studies focused on analyzing recovered COVID-19 patients demonstrate a broad spectrum of persistent and systemic symptoms, which had got the novel terms of “post-COVID syndrome”, “long COVID” and “chronic COVID-19” (2). This new disorder had led to the understanding that the absence of SARS-CoV-2 following COVID-19 does not necessarily mean full recovery (2).

Studies conducted follow-ups on COVID-19 patients indicate that 50-80% of symptomatic COVID-19 patients who recovered report non-specific symptoms, most commonly fatigue, headache, dyspnea, anosmia, and memory complaint (3–5). An Italian study that examined patients after a mean of 60 days from the first COVID-19 symptom on-set had found only 12.6% of the patients completely recovered; 55% had three or more symptoms, and worsened quality of life was observed among 44% of patients (3). Intriguingly, a systematic review and meta-analysis reported more than 50 possible long-term effects of the SAR-CoV-2 infection (6). The chronic phase of COVID-19 is also presented in objective findings; for example, a study conducted in Germany had found that 78% of recently recovered symptomatic COVID-19 patients had at least one chronic symptom; the most common abnormality was myocardial inflammation (60%) (4).

In this issue of the journal, Bertin D et al. documented a case of post-COVID syndrome with a one-year follow-up. This case describes persistent anti-cardiolipin IgG autoantibodies and eosinopenia with ongoing neurologic symptoms, demonstrating the long-term disease course of COVID-19 in many patients. Anti-cardiolipin autoantibodies and eosinopenia were defined as independent factors associated with COVID-19 severity, indicating their active involvement in the progression of the disease (7,8). Additional studies that included follow-up on recovered COVID-19 patients describe similar findings: patients report respiratory, neurologic, and non-specific symptoms, accompanied by the presents of autoantibodies (6). Interestingly, in a one-year prospective cohort study, neurocognitive symptoms frequency were found significantly higher in patients with ANA titer of ≥1:160 in comparison to <1:160 at 12 months post–COVID-19 symptom onset (9). It should be emphasized that the development of autoantibodies, which appears to be common following symptomatic SARS-CoV-2 infection, could act as the preclinical stage of many autoimmune diseases. Thus, the long-term autoimmune implications of SARS-CoV-2 could be severe.

Involvement of the autonomic nervous system dysfunction in post-COVID syndrome

Many viruses are well known to contribute to autoimmunity in genetically pre dispositioned individuals, such as those with human leukocyte antigen B27 (10). SARS-CoV-2 had been associated with numerous autoantibodies (1); some are believed to be the basis of the severe forms of COVID-19 (11). Furthermore, these autoantibodies, along with others, could lead to the multi-organ involvement of post-COVID syndrome, which manifests as broad and unspecific symptoms (6). Autoantibodies against the autonomic nervous system compounds are believed to be an incremental part of the post-COVID syndrome etiology. A study that included post-COVID syndrome patients had unidentified in all the subjects between 2 and 7 different functionally active autoantibodies that acted as receptor agonists, such as β2-adrenoceptor, α1-adrenoceptor, and angiotensin II receptor type 1 receptor (12). Functionally active autoantibodies such as those were present in several neurological and cardiac disorders, which might clarify the onset of neurological and cardiovascular symptoms of the post-COVID syndrome (12).

Post-COVID patients commonly have a clinical presentation similar to the encephalomyelitis/chronic fatigue syndrome (ME/CFS): severe fatigue, sleep disorders, cognition impairments, and different manifestations of autonomic dysfunction exacerbated in physical exercise (6,13–15). ME/CFS has an autoimmune etiology, which can be demonstrated by high titers of autoantibodies against autonomic receptors, such as beta-adrenergic and muscarinic receptors (16,17). These autoantibodies, similar to those found in patients with post-COVID symptoms, lead to unspecific symptoms due to autonomic nervous system dysregulation. In addition to ME/CFS, many features of the post-COVID syndrome are shared with fibromyalgia patients. It had been shown that 189/616 (30.7%) of COVID-19 recovered patients satisfied the American College of Rheumatology criteria for fibromyalgia, 43.4% of which were men (18).

Therapeutic options and vaccination

ME/CFS and fibromyalgia have solid evidence of dysregulated immune involvement (16,17,19). Moreover, current studies suggest that immunosuppression, such as monoclonal anti-CD20 antibody and cyclophosphamide, may benefit patients suffering from ME/CFS (20,21). Such immunosuppressive therapeutic options can assist in the depletion of B cells, thus reducing the functionally active autoantibodies linked to autonomic dysfunction. Beneficial effects had also been demonstrated by the use of anti-ß2 adrenergic receptor-binding immunoadsorption (22). It should be emphasized that such treatment can diminish other pathogenic antibodies that the medical community had not yet recognized. Due to the possible involvement of autoantibodies against the autonomic nervous system in the post-COVID syndrome, similar immunosuppressive options in these patients may be effective, thereby should be investigated.

Most individuals infected by SARS-CoV-2 are asymptomatic or experience mild symptoms (23,24). While the frequency of post-COVID syndrome in such individuals is still uncertain, it seems to be much lower than in symptomatic patients (9). Thus, avoiding COVID-19 with SARS-CoV-2 vaccination could prominently assist in preventing long-term symptoms of COVID-19, lower the prevalence of post-COVID syndrome and help overcome the pandemic. Nonetheless, even with the ongoing heist mass vaccination programs, the COVID-19 pandemic will leave its mark.

Conclusion

Due to the accumulating evidence of persistent post-infectious symptoms reported by numerous recovered patients, the focus of the medical and research communities might need to start shifting focus from the acute phase of COVID-19 to the chronic manifestations of the SARS-CoV-2 infection, referred to as by “post-COVID syndrome”. Post-COVID syndrome presents as non-specific symptoms, most commonly fatigue, headache, dyspnea, anosmia, and memory complaint, which is suspiciously similar to the infection-induced myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and fibromyalgia (15,18). As current studies suggest an involvement of immune-related dysfunction in the development of post-COVID syndrome, immunosuppressive therapeutic options could be beneficial in parallel to heist SARS-CoV-2 vaccination of the population (15,20,21).

Estimating total morbidity burden of COVID-19: relative importance of death and disability

Abstract:

Objective: Calculations of disease burden of COVID-19, used to allocate scarce resources, have historically considered only mortality. However, survivors often develop postinfectious ‘long-COVID’ similar to chronic fatigue syndrome; physical sequelae such as heart damage, or both. This paper quantifies relative contributions of acute case fatality, delayed case fatality, and disability to total morbidity per COVID-19 case.

Study design and setting: Healthy life years lost per COVID-19 case were computed as the sum of (incidence*disability weight*duration) for death and long-COVID by sex and 10-year age category in three plausible scenarios.

Results: In all models, acute mortality was only a small share of total morbidity. For lifelong moderate symptoms, healthy years lost per COVID-19 case ranged from 0.92 (male in his 30s) to 5.71 (girl under 10) and were 3.5 and 3.6 for the oldest females and males. At higher symptom severities, young people and females bore larger shares of morbidity; if survivors’ later mortality increased, morbidity increased most in young people of both sexes.

Conclusions: Under most conditions most COVID-19 morbidity was in survivors. Future research should investigate incidence, risk factors, and clinical course of long-COVID to elucidate total disease burden, and decisionmakers should allocate scarce resources to minimize total morbidity. WHAT IS NEW; KEY FINDINGS: : Under most plausible model scenarios, most COVID-19 morbidity (death + disability) is likely to be due to disability (‘long-COVID’) or delayed death due to organ damage, rather than immediate death. Only if long-COVID resolves (atypical of postinfectious syndromes) is morbidity higher in old than young WHAT THIS ADDS TO WHAT IS KNOWN: : While COVID-19 deaths are numerous, they likely cause less morbidity overall than does disability or organ damage in survivors. Morbidity is highest in females, especially those infected young.

What should change now: Scarce resources such as vaccines should be allocated to minimize morbidity rather than focusing solely on mortality. Data on long-COVID, especially its sex bias, should be collected and publicized.

Clinical Heterogeneity in ME/CFS. A Way to Understand Long-COVID19 Fatigue

Abstract:

The aim of present paper is to identify clinical phenotypes in a cohort of patients affected of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. Ninety-one patients and 22 healthy controls were studied with the following questionnaires, in addition to medical history: visual analogical scale for fatigue and pain, DePaul questionnaire (post-exertional malaise, immune, neuroendocrine), Pittsburgh sleep quality index, COMPASS-31 (dysautonomia), Montreal cognitive assessment, Toulouse-Piéron test (attention), Hospital Anxiety and Depression test and Karnofsky scale. Co-morbidities and drugs-intake were also recorded.

A hierarchical clustering with clinical results was performed. Final study group was made up of 84 patients, mean age 44.41 ± 9.37 years (66 female/18 male) and 22 controls, mean age 45 ± 13.15 years (14 female/8 male). Patients meet diagnostic criteria of Fukuda-1994 and Carruthers-2011. Clustering analysis identify five phenotypes.

Two groups without fibromyalgia were differentiated by various levels of anxiety and depression (13 and 20 patients). The other three groups present fibromyalgia plus a patient without it, but with high scores in pain scale, they were segregated by prevalence of dysautonomia (17), neuroendocrine (15), and immunological affectation (19). Regarding gender, women showed higher scores than men in cognition, pain level and depressive syndrome.

Mathematical tools are a suitable approach to objectify some elusive features in order to understand the syndrome. Clustering unveils phenotypes combining fibromyalgia with varying degrees of dysautonomia, neuroendocrine or immune features and absence of fibromyalgia with high or low levels of anxiety-depression. There is no a specific phenotype for women or men.

Fatigue in post-acute sequelae of SARS-CoV2 (PASC) treated with oxygen-ozone autohemotherapy – preliminary results on 100 patients

Abstract:

Objective: Post-acute sequelae of SARS-CoV2 infection (PASC) are a novel terminology used to describe post-COVID persistent symptoms, mimicking somehow the previously described chronic fatigue syndrome (CFS). In this manuscript, we evaluated a therapeutical approach to address PASC-derived fatigue in a cohort of past-COVID-19 positive patients.

Patients and methods: A number of 100 patients, previously diagnosed as COVID-19 positive subjects and meeting our eligibility criteria, was diagnosed having PASC-related fatigue. They were recruited in the study and treated with oxygen-ozone autohemotherapy (O2-O3-AHT), according to the SIOOT protocol. Patients’ response to O2-O3-AHT and changes in fatigue were measured with the 7-scoring Fatigue Severity Scale (FSS), according to previously published protocols.

Results: Statistics assessed that the effects of O2-O3-AHT on fatigue reduced PASC symptoms by 67%, as a mean, in all the investigated cohort of patients (H = 148.4786 p < 0.0001) (Figure 1). Patients following O2-O3-AHT therapy, quite completely recovered for PASC-associated fatigue, a quote amounting to about two fifths (around 40%) of the whole cohort undergoing ozone treatment and despite most of patients were female subjects, the effect was not influenced by sex distribution (H = 0.7353, p = 0.39117).

Conclusions: Ozone therapy is able to recover normal functionality and to relief pain and discomfort in the form of PASC-associated fatigue in at least 67% of patients suffering from post-COVID sequelae, aside from sex and age distribution.

Evolving phenotypes of non-hospitalized patients that indicate long COVID

Abstract:

Background: For some SARS-CoV-2 survivors, recovery from the acute phase of the infection has been grueling with lingering effects. Many of the symptoms characterized as the post-acute sequelae of COVID-19 (PASC) could have multiple causes or are similarly seen in non-COVID patients. Accurate identification of PASC phenotypes will be important to guide future research and help the healthcare system focus its efforts and resources on adequately controlled age- and gender-specific sequelae of a COVID-19 infection.

Methods: In this retrospective electronic health record (EHR) cohort study, we applied a computational framework for knowledge discovery from clinical data, MLHO, to identify phenotypes that positively associate with a past positive reverse transcription-polymerase chain reaction (RT-PCR) test for COVID-19. We evaluated the post-test phenotypes in two temporal windows at 3-6 and 6-9 months after the test and by age and gender. Data from longitudinal diagnosis records stored in EHRs from Mass General Brigham in the Boston Metropolitan Area was used for the analyses. Statistical analyses were performed on data from March 2020 to June 2021. Study participants included over 96 thousand patients who had tested positive or negative for COVID-19 and were not hospitalized.

Results: We identified 33 phenotypes among different age/gender cohorts or time windows that were positively associated with past SARS-CoV-2 infection. All identified phenotypes were newly recorded in patients’ medical records 2 months or longer after a COVID-19 RT-PCR test in non-hospitalized patients regardless of the test result. Among these phenotypes, a new diagnosis record for anosmia and dysgeusia (OR 2.60, 95% CI [1.94-3.46]), alopecia (OR 3.09, 95% CI [2.53-3.76]), chest pain (OR 1.27, 95% CI [1.09-1.48]), chronic fatigue syndrome (OR 2.60, 95% CI [1.22-2.10]), shortness of breath (OR 1.41, 95% CI [1.22-1.64]), pneumonia (OR 1.66, 95% CI [1.28-2.16]), and type 2 diabetes mellitus (OR 1.41, 95% CI [1.22-1.64]) is one of the most significant indicators of a past COVID-19 infection. Additionally, more new phenotypes were found with increased confidence among the cohorts who were younger than 65.

Conclusions: The findings of this study confirm many of the post-COVID-19 symptoms and suggest that a variety of new diagnoses, including new diabetes mellitus and neurological disorder diagnoses, are more common among those with a history of COVID-19 than those without the infection. Additionally, more than 63% of PASC phenotypes were observed in patients under 65 years of age, pointing out the importance of vaccination to minimize the risk of debilitating post-acute sequelae of COVID-19 among younger adults.

Long COVID and Chronic Fatigue Syndrome: A survey of elderly female survivors in Egypt

Abstract:

Objectives: This study aimed to investigate post COVID 19 symptoms amongst elderly females and whether they could be a risk factor for developing Chronic Fatigue Syndrome (CFS) later on.

Methods: This was a retrospective cross-sectional study, in the form of an online survey. A total of 115 responses were finally included.

Results: The mean age was 73.18±6.42. Eighty-nine reported symptoms in the post recovery period; of these 54 had no symptoms of CFS, 60 were possible, and only 1 was probable. Fatigue was reported by 66, musculoskeletal symptoms by 56, and sleep problems by 73. Twenty-nine patients visited a doctor’s office as a result. Post recovery symptoms were significantly related to stress, sadness and sleep disturbances. Also, stress, sadness, sleep disturbances, fatigue, cognitive impairment, and recurrent falls were all significantly associated with CFS like symptoms.

Conclusions: From our findings the presence of fatigue, cognitive impairment, stress, sadness, sleep disturbances, and recurrent falls in the post-recovery period were all significantly associated with CFS like symptoms. To conclude it would be reasonable to screen for Long COVID and consider the potential for developing CFS later on. Whether it can be a risk factor for developing CFS like other viral infections will need more larger scale studies to confirm this.

Long COVID: Is it really myalgic encephalomyelitis? Bibliographic review and considerations

Abstract:

Clinical sequelae of a disease as widespread as COVID-19 can be of great importance for primary care due to their prevalence and the morbidity they entail. The definition of long COVID and the establishment of its temporality are various, but some authors consider possible that this syndrome is actually myalgic encephalomyelitis.

Similarities are observed when comparing the International Consensus Criteria for the diagnosis of myalgic encephalomyelitis with the symptoms described for long COVID. Blood tests, pulse oximetry, chest radiography, and thoracic ultrasound are recommended in patients with persistent symptoms after acute infection. Management in both conditions consists of treating the main symptoms.
