Immune Adsorption for the Treatment of Fatigue-Dominant Long-/Post-COVID Syndrome

Introduction:

Following an infection with SARS-CoV-2, a relevant proportion of patients suffer from fatigue-dominant long-/post-COVID syndrome. In 57% of patients with long-/post-COVID syndrome, who were treated in a university hospital, increased levels of autoantibodies (AABs) to G-protein-coupled neurotransmitter receptors (including ß-adrenergic and muscarinic) were detected ().

Reduction of ß-adrenergic AABs by immunoadsorption therapy was associated with clinical improvement in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) (). Increasingly, reports of individual cases of successful treatment of long/post-COVID syndrome with the help of apheresis techniques have been widely disseminated via social media. By contrast, cases or studies with negative outcomes are much less likely to receive proper attention. Given the overall lack of data to date, medical societies are calling for a broader scientific basis, to which we would like to contribute with this case series.

Neuroimmunological Effect of Vitamin D on Neuropsychiatric Long COVID Syndrome: A Review

Abstract:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the coronavirus disease 2019 (COVID-19). COVID-19 is now recognized as a multiorgan disease with a broad spectrum of manifestations. A substantial proportion of individuals who have recovered from COVID-19 are experiencing persistent, prolonged, and often incapacitating sequelae, collectively referred to as long COVID. To date, definitive diagnostic criteria for long COVID diagnosis remain elusive.
An emerging public health threat is neuropsychiatric long COVID, encompassing a broad range of manifestations, such as sleep disturbance, anxiety, depression, brain fog, and fatigue. Although the precise mechanisms underlying the neuropsychiatric complications of long COVID are presently not fully elucidated, neural cytolytic effects, neuroinflammation, cerebral microvascular compromise, breakdown of the blood–brain barrier (BBB), thrombosis, hypoxia, neurotransmitter dysregulation, and provoked neurodegeneration are pathophysiologically linked to long-term neuropsychiatric consequences, in addition to systemic hyperinflammation and maladaptation of the renin–angiotensin–aldosterone system.
Vitamin D, a fat-soluble secosteroid, is a potent immunomodulatory hormone with potential beneficial effects on anti-inflammatory responses, neuroprotection, monoamine neurotransmission, BBB integrity, vasculometabolic functions, gut microbiota, and telomere stability in different phases of SARS-CoV-2 infection, acting through both genomic and nongenomic pathways.
Here, we provide an up-to-date review of the potential mechanisms and pathophysiology of neuropsychiatric long COVID syndrome and the plausible neurological contributions of vitamin D in mitigating the effects of long COVID.

The global challenges of the long COVID-19

Abstract:

COVID-19 may lead to a perseverance of symptoms after recovery from the disease, a condition known as long COVID, characterized by continual cognitive, somatic and behavioral symptoms. SARS-CoV-2 infection triggers different molecular to tissue level events, given by the inherent features of each patient. The potential pathological changes which determine the array of symptoms are arduous to anticipate.

There is an increasing interest to develop treatment strategies for survivors who experience a long COVID. In this respect, considering the anti-inflammatory, anti-oxidative and cytoprotective effects of melatonin (MEL) on viral infections, its potential links with COVID-19 should be researched. Several studies suggest that administration of MEL may prevent clinical deterioration and even death in patients with acute and long COVID-19.

This paper briefly reviews the current status of knowledge of the pathogenic, clinical, and therapeutic features of Long COVID-19 and forthcoming directions for research and implications for the management and therapy of the disease are analyzed.

Efficiency of comprehensive rehabilitation of chronic fatigue syndrome due to coronavirus infections COVID-19

Abstract:

The aim of the study was to study the effectiveness of complex rehabilitation in patients with chronic fatigue syndrome caused by coronavirus infections.

In 120 patients with a confirmed diagnosis of SARS-CoV-2 (COVID-19) aged 20-58 years, post-COVID syndrome or chronic fatigue syndrome was detected, 52 men and 68 women. Patients had asthenic, cognitive, vegetative manifestations, sleep disorders, smell and taste disorders, anxiety and depression.

Patients received drug therapy: succinic acid preparations, brain metabolic drugs, stimulating antidepressants, sleeping pills – melatonin and B vitamins, among other things, received micropolarization of the head and translingualneurostimulation.

The results of treatment confirmed the effectiveness of the proposed conservative therapy. The neurological symptoms of post-COVID syndrome – chronic fatigue syndrome (CFS) were studied in 120 patients with a confirmed diagnosis of SARS-CoV-2 (COVID-19), aged 20-58 years.

Patients were examined according to the “Questionnaire for the detection of asthenia”, “Mini Mental State Assessment (MMSE)”, et.al. Sleep disorders were studied using the Epworth Sleepiness Scale, anxiety and depression were studied using the “Questionnaire for Determining Anxiety and Depression”.

The patients were divided into 2 groups: the main group (MG) – 69 patients and the control group (CG) – 51 patients. Patients with MG and CG received drug therapy: succinic acid preparations, brain metabolic drugs, stimulating antidepressants, sleeping pills – melatonin and B vitamins. And patients with MG, among other things, received micropolarization of the head and translingualneurostimulation.

The Potential Role of Hypothalamic Phospholipid Liposomes in the Supportive Therapy of Some Manifestations of Post-COVID-19 Condition: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Brain Fog

Abstract:

Post-COVID-19 condition (commonly known as Long COVID) is a heterogeneous clinical condition in which Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and brain fog stand out among the different clinical symptoms and syndromes. Cerebral metabolic alterations and neuroendocrine disorders seem to constitute an important part of the pathophysiology of Post-COVID-19 condition (PCC).

Given the substantial lack of specific drugs and effective therapeutic strategies, hypothalamic phospholipid liposomes, which have been on the market for several years as adjuvant therapy for cerebral metabolic alterations resulting from neuroendocrine disorders, might represent a potential option in an overall therapeutic strategy that aims to control PCC-associated symptoms and syndromes. Their pharmacological mechanisms and clinical effects strongly support their potential effectiveness in PCC. Our initial clinical experience seems to corroborate this rationale. Further controlled clinical research is warranted in order to verify this hypothesis.

Long and Short-term Metformin Consumption as a Potential Therapy to Prevent Complications of COVID-19

Abstract:

Purpose: The aim of the study is to evaluate the effect of metformin in complication improvement of hospitalized patients with COVID-19.

Methods: This was a randomized clinical trial that involved 189 patients with confirmed COVID-19 infection. Patients in the intervention group received metformin-500 mg twice daily. Patients who received metformin before admission were excluded from the control group. Patients who were discharged before taking at least 2000 mg of metformin were excluded from the study. Primary outcomes were vital signs, need for ICU admission, need for intubation, and mortality.

Results: Data showed that patients with diabetes with previous metformin in their regimen had lower percentages of ICU admission and death in comparison with patients without diabetes (11.3% vs. 26.1% (P=0.014) and 4.9% vs. 23.9% (P≤0.001), respectively). Admission time characteristics were the same for both groups except for diabetes and hyperlipidemia, which were significantly different between the two groups. Observations of naproxen consumption on endpoints, duration of hospitalization, and the levels of spO2 did not show any significant differences between the intervention and the control group. The adjusted OR for intubation in the intervention group versus the control group was 0.21 [95% CI, 0.04-0.99 (P=0.047)].

Conclusion: In this trial, metformin consumption had no effect on mortality and ICU admission rates in non-diabetic patients. However, metformin improved COVID-19 complications in diabetic patients who had been receiving metformin prior to COVID-19 infection, and it significantly lowered the intubation rates.

Treatment of Brain Fog of Long COVID Syndrome: A Hypothesis

Abstract:

The emergence of the SARS-CoV-2 (COVID-19) virus has exacted a significant toll on the global population in terms of fatalities, health consequences, and economics. As of February 2023, there have been almost 800 million confirmed cases of the disorder reported to the WHO [1], although the actual case-positive rate is estimated to be much higher.

While many cases recover, the mortality rate associated with the illness is about 1% (based on the WHO data). Most patients experience the illness as a mild to moderate disorder and recover without significant sequelae. However, as the COVID-19 pandemic has continued, there has emerged a significant group of COVID-19 survivors who experience persistent symptoms beyond the acute course of the illness.

As many as one in eight patients report persistent symptoms 90 to 150 days after the initial infection [2]. These so-called Long COVID or post-COVID syndrome patients are mostly drawn from those who were hospitalised for the disorder, but both non-hospitalised and vaccinated subjects may also experience the syndrome [3]. While an agreed definition of Long COVID is yet to be settled, a multiplicity of symptoms affecting most major organ systems has been reported in patients.

Common Long COVID symptoms include fatigue, dyspnoea, headaches, myalgia, anosmia, dysgeusia, cognitive symptoms, and mental disorders such as depression and anxiety [4]. It is estimated that approximately a third of patients with Long COVID exhibit either fatigue, cognitive impairment, or both up to 12 weeks after a confirmed diagnosis of COVID-19 [5].

Long Covid & Antidepressants

Abstract:

Three years into this historic pandemic, the scientific and healthcare communities continue to learn agreat deal regarding COVID-19, the disease that is produced by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The most urgent and immediate focus has been on vaccine development for diseaseprevention/mitigation and on identification of effective therapeutic interventions for acute phase of illness. However, attention is increasingly being placed on formulating treatment strategies for individuals who arepost-COVID-19 and experiencing a syndrome of persistent cognitive, somatic and behavioral symptoms that is being referred to as long COVID.

In addition to identifying novel compounds that may improve outcome ineither acute or residual COVID-19, an alternate and parallel strategy is to repurpose or reposition drugs which have been approved for other conditions and subsequently assess their safety and efficacy when applied toCOVID-19. In this light, antidepressant medications, particularly serotonin reuptake inhibitors, have garnered attention amidst evidence supporting their anti-inflammatory and anti-viral properties. Results from several preliminary studies suggest that early administration of antidepressants may prevent clinical deterioration and even death in patients with acute COVID-19.

In this article, we present purported anti-inflammatory mechanisms of the antidepressants, review results from studies that have appeared in the literature to date regarding antidepressants and acute COVID-19, and discuss the possible utility of antidepressants as a potential therapeutic resource for long COVID.

L-Arginine in Restoring ‘Immune Dysregulation’ in Long COVID: It’s the Therapeutic Role Beyond the Routine Dietary Supplement!

Abstract:

COVID-19 pandemic is over now and we are in great peace of relief after three years. This pandemic has observed significant impact on quality of life globally and the put unforgettable imprints on history of mankind. Reason for more havoc in this pandemic was less studied virus by medical scientists regarding its pathophysiology, available treatment options and lack of effective vaccine to tackle this dragon. COVID-19 is the first observed and reported pandemic of corona virus related global disease apart from its previous SARS and MERS. Fast track developments in medical treatment options due to this ultrafast digital and artificial intelligence techniques have curtailed mortality on large scale globally.
Although mortality is significantly reduced, morbidity is documented on a large scale worldwide in this pandemic. Morbidity due to COVID-19 now called as ‘Long COVID’, which is underreported & half-heartedly evaluated globally. Long COVID is related to persistent immune dysregulation occurs during evolution of COVID-19 as natural trend of disease.
Immune dysregulation has documented during course of active viremia, during recovery of viral illness and after post viral phase. Immune dysregulation occurs in ‘selected group’ of cases irrespective of disease severity and vaccination status and observed in cases with negligible illness to advanced one mandates further research. Thus, Immune dysregulation in COVID-19 is predominant cause for long covid and leading to brainstorming effect on medical scientists and researchers as of today.
Globally, one third of recovered or affected cases of COVID-19 are facing long covid and needs prompt treatment options to tackle this dragon related long term effect on body. ‘Immunomodulatory’ or immunity modifying agents are the primary targets to curtail immune dysregulation and long covid. Some experts recommend ‘disease modifying agents’ to treat long covid cases. Still, many miles to go to reach to effective treatment options for long covid and we don’t have effective options for this ‘health issue of global concern’.
L-Arginine is amino acid with multiple beneficial effects such as immunomodulatory effects which will regulates immunological response in inhibit dysregulated immune system additional to its universally known antioxidant, vasodilatory and regenerative and cellular proliferation effects on immune cells. These Immunomodulatory and or diseases modifying effects of L-Arginine makes it the future candidate with ‘game changer’ role for management of Long covid resulting from immune dysregulation as a core pathophysiologic pathway of this Dragon Pandemic.

Compounding for the Treatment of COVID-19 and Long COVID, Part 4: The Legacy of Chronic COVID

Abstract:

People infected by severe acute respiratory coronavirus 2 (SARS-CoV-2) risk the development of not only acute coronavirus- disease-2019 (COVID-19) – the signs and symptoms of which range from none to severe illness that requires intensive treatment – but also long COVID (i.e., chronic COVID), a cyclical, progressive, multiphasic illness characterized by myriad debilitating conditions that persist long term. In some patients, those sequelae result in psychiatric disorders that can lead to suicide or other forms of self-harm, incidences of which have increased exponentially since before the COVID pandemic. It has been suggested that long COVID develops in an estimated 10% to 35% of people diagnosed as having COVID-19.

Because the success of therapy for either form of COVID can be complicated by each patient’s pharmacogenomic profile, personal treatment preferences, medical needs, and/or dosing requirements, we have found that in some people so afflicted, manufactured medications are ineffective or intolerable, and that for those individuals, a customized compound often provides relief and promotes recovery. The primary focus of this article is long COVID. The pathogenesis of that disease is reviewed, therapies for the signs and symptoms it engenders are examined, and 2 compounded formulations effective in treating both acute and chronic COVID-19 are presented.
