Role of Vitamin D Supplementation for Symptoms and Lung Function Improvement in Long COVID Patient

Abstract:

Post-Acute COVID-19 Syndrome (PACS) or acute post-COVID-19 syndrome or also known as “Long Covid”, is a collection of persistent symptoms and long-term complications more than four weeks after the onset of initial symptoms. One of the leading causes of these long-term complications is pulmonary fibrosis, with an incidence of almost 25% in patients a year after hospitalization. Vitamin D is an important substance to our body homeostasis and regulation. Vitamin D has pleiotropic effect as pulmonary antifibrosis. This research aims to directly provide vitamin D3 supplements, especially in improving lung function in pulmonary fibrosis patients after COVID-19 infection.

This study was a one-group, quasiexperimental pretest-posttest design conducted at Labuang Baji hospitals in the eastern part of Indonesia. The population of this study was patients post-covid-19 infection with negative PCR results at least three months, had persistent symptoms of covid 19, and a CT scan confirmed pulmonary fibrosis or destroyed lung results. Lung function was measured using spirometry before and after the intervention (Vitamin D3 5000 IU supplementation with a frequency of once per day for two months). This study included 20 cases of Lung Fibrosis post-Covid-19. The majority of respondents were women and between the ages of 40 and 49. Among 20 patients, most of them fatigue or dyspneu or shortness of breath as their main symptoms.

After 2-months supplementation of Vitamin D 5000 IU, number of patients who had shortness of breath and fatigue reduced significantly (From 11 to 3 and from 11 to 2 patients, respectively). 85% of our patient had deficient-insufficient status of vitamin D. We found restrictive pattern as a dominant lung function in our patient. There was significant improvement in lung function status after 2-months vitamin D supplementation (p=0.02). Vitamin D supplementation for Long COVID may have benefit for symptoms and lung function improvement.

Antihistamines improve cardiovascular manifestations and other symptoms of Long-COVID attributed to Mast Cell Activation

Abstract:

Introduction: Long-COVID is a hardly defined condition and there are no effective therapies. Cardiovascular manifestations of Long-COVID include high heart rate, postural tachycardia, and palpitations. Previous studies have suggested that mast cell activation (MCA) may play a role in the pathophysiology of Long-COVID, including in the mechanisms of its cardiovascular manifestations. The aim of the study was to evaluate the effectiveness of a treatment with blockers of histamine receptors in Long-COVID patients who did not respond to other therapies.

Methods: Fourteen patients (F/M=9/5; 49.5±11.5 years) and 13 controls (F/M=8/5; 47.3±8.0 years) with Long-COVID symptoms attributed to MCA were evaluated. Patients were treated with fexofenadine (180 mg/day) and famotidine (40 mg/day). Fatigue, brain fog, abdominal disorders, and increased heart rate were evaluated in treated and untreated patients at baseline and 20 days later.

Results: Long-COVID symptoms disappeared completely in 29% of treated patients. There was significant improvement in each of the considered symptoms (improved or disappeared) in all treated patients, and the improvement grade was significantly greater in treated patients with respect to controls. No significant differences in the outcomes were observed in the controls.

Our data confirm that histamine receptors blockade may be an effective target to successfully treat long-COVID. Our finding supports the underlying role of MCA in the pathophysiology of Long-COVID.

Approaches towards menstrual cycle disorder therapy in reproductive-aged women with long COVID

Abstract:

Background. The mirror of a female’s reproductive health is the menstrual cycle. The SARS-CoV-2 pandemic itself acts as a significant stressor. This leads to women’s overall health and life quality disturbance. Moreover, patients struggle with long COVID effects, which is a prolongation of symptoms after recovery. Due to the expression of angiotensin-converting enzyme type 2 receptors in the intestinal mucosa and inflammation, the gastrointestinal (GI) tract is also triggered by the virus.

Objectives. To assess the efficacy of the chosen treatment approach in women with changes in premenstrual syndrome and cyclicity due to long COVID with or without GI symptoms.

Material and methods. A single-centre longitudinal interventional study was organized. Were studied data from the conducted tests (progesterone level, ultrasound follicle scan, etc.) and surveys. Then the effectiveness of the suggested treatment with the use of oral and vaginal forms of progesterone was evaluated. The study was held in the Kyiv City Center of Reproductive and Perinatal Medicine (Ukraine) from January to June 2021.

Results. On average 78% patients without GI symptoms experienced relief after 3 months and 89% patients after 6 months of suggested treatment. 71% patients with GI symptoms experienced improvement after 3 and 87% of them after 6 months. The vaginal progesterone had better results compared to oral form. Averagely 6–8% experienced side effects (nausea, hypotension, less compliance) due to progesterone intake. The vaginal micronised progesterone also presented better results than oral with fewer side effects compared to the total number of participants.

Conclusions. The proposed approach has shown particular correction of the menstrual cycle disturbances in women with long COVID. Vaginal micronized progesterone offers more promising outcomes in patients with GI symptoms and disrupted absorption, compared to the oral form.
Further investigation is required for a more reasonable conclusion.

Detrimental effects of COVID-19 in the brain and therapeutic options for long COVID: The role of Epstein–Barr virus and the gut–brain axis

Abstract:

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has resulted in a serious public health burden worldwide. In addition to respiratory, heart, and gastrointestinal symptoms, patients infected with SARS-CoV-2 experience a number of persistent neurological and psychiatric symptoms, known as long COVID or “brain fog”. Studies of autopsy samples from patients who died from COVID-19 detected SARS-CoV-2 in the brain. Furthermore, increasing evidence shows that Epstein–Barr virus (EBV) reactivation after SARS-CoV-2 infection might play a role in long COVID symptoms.

Moreover, alterations in the microbiome after SARS-CoV-2 infection might contribute to acute and long COVID symptoms. In this article, the author reviews the detrimental effects of COVID-19 on the brain, and the biological mechanisms (e.g., EBV reactivation, and changes in the gut, nasal, oral, or lung microbiomes) underlying long COVID.

In addition, the author discusses potential therapeutic approaches based on the gut–brain axis, including plant-based diet, probiotics and prebiotics, fecal microbiota transplantation, and vagus nerve stimulation, and sigma-1 receptor agonist fluvoxamine.

A Pilot Study of Short-Course Oral Vitamin A and Aerosolised Diffuser Olfactory Training for the Treatment of Smell Loss in Long COVID

Abstract:

Background: Olfactory dysfunction (OD) is a common neurosensory manifestation in long COVID. An effective and safe treatment against COVID-19-related OD is needed.
Methods: This pilot trial recruited long COVID patients with persistent OD. Participants were randomly assigned to receive short-course (14 days) oral vitamin A (VitA; 25,000 IU per day) and aerosolised diffuser olfactory training (OT) thrice daily (combination), OT alone (standard care), or observation (control) for 4 weeks. The primary outcome was differences in olfactory function by butanol threshold tests (BTT) between baseline and end-of-treatment. Secondary outcomes included smell identification tests (SIT), structural MRI brain, and serial seed-based functional connectivity (FC) analyses in the olfactory cortical network by resting-state functional MRI (rs–fMRI).
Results: A total of 24 participants were randomly assigned to receive either combination treatment (n = 10), standard care (n = 9), or control (n = 5). Median OD duration was 157 days (IQR 127–175). Mean baseline BTT score was 2.3 (SD 1.1). At end-of-treatment, mean BTT scores were significantly higher for the combination group than control (p < 0.001, MD = 4.4, 95% CI 1.7 to 7.2) and standard care (p = 0.009) groups. Interval SIT scores increased significantly (p = 0.009) in the combination group. rs–fMRI showed significantly higher FC in the combination group when compared to other groups. At end-of-treatment, positive correlations were found in the increased FC at left inferior frontal gyrus and clinically significant improvements in measured BTT (r = 0.858, p < 0.001) and SIT (r = 0.548, p = 0.042) scores for the combination group.
Conclusions: Short-course oral VitA and aerosolised diffuser OT was effective as a combination treatment for persistent OD in long COVID.

The potential role of Rhodiola rosea L. extract WS® 1375 for patients with post-COVID-19 fatigue

Abstract:

Fatigue and physical exhaustion are the dominant symptoms of post-coronavirus (COVID-19) conditions that might even develop after only mild acute disease. Post-acute infection syndromes have been observed after various infections, e.g., Coxiella burnetii, Ebola, Dengue, Polio, severe acute respiratory syndrome (SARS), Chikungunya, West Nile Virus, Borrelia, or Giardina lamblia. The similarities in symptoms and courses suggest a high likelihood of common pathogenetic pathways, including persistent infection, autoimmune reactions, dysregulation of the microbiome, inability to repair tissue damage, or endothelial dysfunction.

Some herbal drugs, so-called adaptogens, exert effects resulting in an increase in the resistance or regulatory potential of organisms against biological, chemical and physical burden or stress. Therefore, it seems possible that adaptogens can be helpful in cases of post-COVID-19 symptoms. One of these adaptogens is Rhodiola rosea L. The proprietary ethanolic extract made from roots and rhizomes of Rhodiola rosea WS® 1375 has been reported to modulate neuroinflammation in response to stress stimuli in preclinical models. Moreover, it activated the synthesis or resynthesis of adenosine triphosphate (ATP) in skeletal muscle mitochondria and counteracted muscle fatigue.

In three clinical trials with subjects suffering from burnout symptoms, prolonged or chronic fatigue symptoms or life-stress symptoms, clinically relevant improvements of fatigue and exhaustion were reported over 4 to 12 weeks of treatment at a very favorable tolerability and safety profile in heterogeneous patient populations. In conclusion, Rhodiola rosea extract WS® 1375 has a promising pharmacological and therapeutic profile for the treatment of fatigue and physical exhaustion associated with post-COVID-19 conditions.

Chronic inflammation, neuroglia dysfunction, and plasmalogen deficiency as a new pathobiological hypothesis addressing the overlap between post-COVID-19 symptoms and myalgic encephalomyelitis/chronic fatigue syndrome

Highlights:

  • Plasmalogens (Pls) are lipids containing a vinyl-ether bond in their glycerol backbone
  • Pls have antioxidant properties and are important for curved membrane assemblies
  • Post-COVID-19 symptoms are highly prevalent and share several features with ME/CFS
  • Pls depletion is a shared biological hallmark of ME/CFS and acute COVID-19 syndrome
  • Pls replacement is a promising tool against neuroinflammation in these two conditions

Abstract:

After five waves of COVID-19 outbreaks, it has been recognized that a significant portion of the affected individuals developed long-term debilitating symptoms marked by chronic fatigue, cognitive difficulties (“brain fog”), post-exertional malaise, and autonomic dysfunction. The onset, progression, and clinical presentation of this condition, generically named post-COVID-19 syndrome, overlap significantly with another enigmatic condition, referred to as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).

Several pathobiological mechanisms have been proposed for ME/CFS, including redox imbalance, systemic and central nervous system inflammation, and mitochondrial dysfunction. Chronic inflammation and glial pathological reactivity are common hallmarks of several neurodegenerative and neuropsychiatric disorders and have been consistently associated with reduced central and peripheral levels of plasmalogens, one of the major phospholipid components of cell membranes with several homeostatic functions.

Of great interest, recent evidence revealed a significant reduction of plasmalogens contents, biosynthesis, and metabolism in ME/CFS and acute COVID-19, with a strong association to symptom severity and other relevant clinical outcomes. These bioactive lipids have increasingly attracted attention due to their reduced levels representing a common pathophysiological manifestation between several disorders associated with aging and chronic inflammation. However, alterations in plasmalogen levels or their lipidic metabolism have not yet been examined in individuals suffering from post-COVID-19 symptoms.

Here, we proposed a pathobiological model for post-COVID-19 and ME/CFS based on their common inflammation and dysfunctional glial reactivity, and highlighted the emerging implications of plasmalogen deficiency in the underlying mechanisms. Along with the promising outcomes of plasmalogen replacement therapy (PRT) for various neurodegenerative/neuropsychiatric disorders, we sought to propose PRT as a simple, effective, and safe strategy for the potential relief of the debilitating symptoms associated with ME/CFS and post-COVID-19 syndrome.

The Role of Hypothalamic Phospholipid Liposomes in the Supportive Therapy of Some Manifestations of Long Covid: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Brain Fog

Abstract:

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. The cerebral metabolic alterations and neuroendocrine disorders seem to constitute an important part of Long Covid.

Given the substantial lack of drugs and effective therapeutic strategies, hypothalamic phospholipid liposomes which have been on the market for several years as adjuvant therapy of cerebral metabolic alterations resulting from neuroendocrine disorders, can be taken into consideration in an overall therapeutic strategy that aims to control the Long Covid associated symptoms and syndromes. Their pharmacological mechanisms and clinical effects strongly support their usefulness in Long Covid. Our initial clinical experience corroborates this rationale. Further research is imperative in order to obtain robust clinical evidence.
