Post-COVID-19 neuropsychiatric manifestations among COVID-19 survivors suffering from migraine: a case-control study

Abstract:

Background: The burden of post-coronavirus disease (COVID)-19 symptoms has been increasing and is of great concern in patients with pre-existing chronic medical conditions.This study aimed to delineate the post-COVID-19 neuropsychiatric symptoms among migraine patients compared to the non-migraine control group.

Methods: Two groups, each of 204 COVID-19 survivors, were enrolled in the study after 3 months of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, one group fulfilling the episodic migraine criteria and the other serving as a matching control group. Subjects were evaluated through an in-person interview for post-COVID-19 neuropsychiatric symptoms, including detailed headache patterns and severity, using the visual analogue scale.

Results: The Frequency of headache during the acute phase of COVID-19 was more frequent in migraine patients (OR = 1.60, 95%CI = 1.04-2.45, P-value = 0.031). The reported significant post-COVID-19 neuropsychiatric symptoms in migraine patients compared to controls were fatigue (OR = 1.662, 95%CI = 1.064-2.596, P-value = 0.025), anosmia/hyposmia (OR = 2.06, 95%CI = 1.164- 3.645, P-value = 0.012), cacosmia (OR = 2.663, 95%CI = 1.145-6.195, P-value = 0.019), depression (OR = 2.259, 95%CI = 1.284- 3.975, P-value = 0.004), anxiety (OR = 3.267, 95%CI = 1.747- 6.108, P-value ≤ 0.001), insomnia (OR = 2.203, 95%CI = 1.298- 3.739, P-value = 0.003), and headache (OR = 3.148, 95%CI = 1.616-6.136, P-value = ≤ 0.001).While there was no statistically significant difference between migraine patients and controls regarding the post-COVID-19 functional status score (P-value = 0.102). The pattern of post-COVID-19 headache was reported as chronic headache transformation in 17.6% of the migraine group, with the median intensity rate being 5.5 and IQR (3-7). In the control group, 14% experienced chronic headache attributed to systemic viral infection with a median intensity rate of 2 and IQR (2-5), while 12% experienced a new daily persistent headache with a median intensity of 5 and IQR (1-6).

Conclusion: The study highlighted the importance of follow-up migraine patients upon recovery from COVID-19 infection, being more vulnerable to post-COVID-19 symptoms.

The COVID-19 Pandemic and Post-Infection Irritable Bowel Syndrome: What Lies Ahead for Gastroenterologists

Clinical Problem

An increasingly recognized subset of patients develops post-infection sequelae also described as long COVID or postacute COVID-19 syndrome (PACS). These patients experience a myriad of neurologic, respiratory, cardiac, psychiatric, and/or GI symptoms that persist for 4 weeks or more from the initial diagnosis of SARS-CoV-2.

Epidemiology

In a survey study of 749 survivors, 29% reported at least 1 new chronic GI symptom 6 months after their COVID-19 infection, with heartburn, constipation, diarrhea, and abdominal pain being the most common.2 Of the patients with abdominal pain, 39% met Rome IV criteria for irritable bowel syndrome (IBS). Other studies also reported a 30%–40% prevalence of GI PACS. Additionally, COVID-19 infection was associated with worsening severity of preexisting IBS symptoms. Some risk factors for GI PACS include the presence of GI symptoms during acute infection, psychiatric diagnoses (depression, anxiety) both pre- and post-COVID-19, need for hospitalization during acute illness, and loss of smell and taste. Infectious gastroenteritis is an established risk-factor for development of disorders of gut-brain interaction (DGBI), particularly post-infection IBS (PI-IBS). Many of the risk factors for GI PACS described are also known predisposing factors for PI-IBS, with some exceptions, such as female gender, a risk factor for PI-IBS but not consistently associated with GI PACS. In addition to IBS, other de novo DGBIs, such as functional dyspepsia, heartburn, chest pain, and dysphagia, can be experienced in the spectrum of GI PACS.

Disease Mechanisms

The pathophysiology of PACS including that of the GI manifestations is incompletely understood; however, it is likely multifactorial (Figure 1). Epithelial invasion by SARS-CoV-2 is substantiated by the high expression levels of angiotensin-converting enzyme-2 on the enterocytes and colonocytes. The angiotensin-converting enzyme-2 is a negative regulator of the renin-angiotensin system and has a protective cellular role, including in the intestinal tract. Following the entry of SARS-CoV-2 in the cell, angiotensin-converting enzyme-2 protein is downregulated, resulting in an increase in angiotensin-II, the likely molecular mechanism of severe acute respiratory syndrome and systemic inflammatory response development with this coronavirus. Intestinal microbial dysbiosis has also been associated with acute SARS-CoV-2 infection and PACS. Long-term respiratory dysfunction after COVID-19 is associated with altered gut microbiota and persistently elevated lipopolysaccharide-binding protein levels. One study showed that dysbiosis in COVID-19 patients continued throughout their hospitalizations and up to 21 days from disease onset, with a decrease in health-promoting, short-chain fatty acid–forming bacteria.3 Gut microbiome of patients with PACS was characterized by higher levels of Ruminococcus gnavus and Bacteroides vulgatus, and lower levels of Faecalibacterium prausnitzii. Interestingly, presence of butyrate-producing bacteria showed an inverse correlation with development of PACS at 6 months.4 A recent study also suggested that salivary microbiome during acute infection may predict the development of GI PACS.5

Clinical, sociodemographic and environmental factors impact post-COVID-19 syndrome

Abstract:

Background: Sociodemographic and environmental factors are associated with incidence, severity, and mortality of COVID-19. However, little is known about the role of such factors in persisting symptoms among recovering patients. We designed a cohort study of hospitalized COVID-19 survivors to describe persistent symptoms and identify factors associated with post-COVID-19 syndrome.

Methods: We included patients hospitalized between March to August 2020 who were alive six months after hospitalization. We collected individual and clinical characteristics during hospitalization and at follow-up assessed ten symptoms with standardized scales, 19 yes/no symptoms, a functional status and a quality-of-life scale and performed four clinical tests. We examined individual exposure to greenspace and air pollution and considered neighbourhood´s population density and socioeconomic conditions as contextual factors in multilevel regression analysis.

Results: We included 749 patients with a median follow-up of 200 (IQR = 185-235) days, and 618 (83%) had at least one of the ten symptoms measured with scales. Pain (41%), fatigue (38%) and posttraumatic stress disorder (35%) were the most frequent. COVID-19 severity, comorbidities, BMI, female sex, younger age, and low socioeconomic position were associated with different symptoms. Exposure to ambient air pollution was associated with higher dyspnoea and fatigue scores and lower functional status.

Conclusions: We identified a high frequency of persistent symptoms among COVID-19 survivors that were associated with clinical, sociodemographic, and environmental variables. These findings indicate that most patients recovering from COVID-19 will need post-discharge care, and an additional burden to health care systems, especially in LMICs, should be expected.

Long COVID Symptomatology After 12 Months and Its Impact on Quality of Life According to Initial Coronavirus Disease 2019 Disease Severity

Abstract:

Background: “Long COVID” is characterized by a variety of symptoms and an important burden for affected people. Our objective was to describe long COVID symptomatology according to initial coronavirus disease 2019 (COVID-19) severity.

Methods: Predi-COVID cohort study participants, recruited at the time of acute COVID-19 infection, completed a detailed 12-month symptom and quality of life questionnaire. Frequencies and co-occurrences of symptoms were assessed.

Results: Among the 289 participants who fully completed the 12-month questionnaire, 59.5% reported at least 1 symptom, with a median of 6 symptoms. Participants with an initial moderate or severe acute illness declared more frequently 1 or more symptoms (82.6% vs 38.6%, P < .001) and had on average 6.8 more symptoms (95% confidence interval, 4.18-9.38) than initially asymptomatic participants who developed symptoms after the acute infection. Overall, 12.5% of the participants could not envisage coping with their symptoms in the long term. Frequently reported symptoms, such as neurological and cardiovascular symptoms, but also less frequent ones such as gastrointestinal symptoms, tended to cluster.

Conclusions: Frequencies and burden of symptoms present 12 months after acute COVID-19 infection increased with the severity of the acute illness. Long COVID likely consists of multiple subcategories rather than a single entity. This work will contribute to the better understanding of long COVID and to the definition of precision health strategies.

A Review of Respiratory Post-Acute Sequelae of COVID-19 (PASC) and the Potential Benefits of Pulmonary Rehabilitation

Abstract:

With the SARS-CoV-2 pandemic continuing into its third year, the number of patients who survive acute COVID-19 infection but go on to develop long-term symptoms is increasing daily. Those individuals who experience one or more of a variety of persistent symptoms post-COVID-19 are now diagnosed with the syndrome called post-acute sequelae of COVID-19 (PASC), often colloquially called “Long COVID.” This article discusses relevant research and current hypotheses regarding the pathophysiology and management of respiratory symptoms of PASC, in order to provide primary care physicians with context for management of this heterogeneous population. We focus on the growing body of research that supports the use of pulmonary rehabilitation for patients with PASC to improve symptoms and quality of life.

Cognitive Complications of COVID-19 Infection

Abstract:

SARS-CoV-2 is associated with a post-infectious neurocognitive syndrome characterized by fatigue and deficits in attention, memory, and executive function. As screening cognitive testing generally remains normal, the pathophysiologic basis of these symptoms remains controversial and there is no standardized treatment paradigm.

We present a clinical case demonstrative of typical neurocognitive sequelae of SARS-CoV-2 infection, highlighting medical and social factors that may have contributed to the severity of symptoms. We discuss the pathophysiologic evidence for cognitive “brain fog” following COVID-19 infection as well as lifestyle changes and rehabilitation strategies that may improve recovery. As the benefits of pharmacologic therapy remain unproven, we close with a brief discussion of medication options that might be appropriate targets for future clinical trials in the context of rehabilitative treatment.

Prevalence of symptoms, comorbidities, fibrin amyloid microclots and platelet pathology in individuals with Long COVID/Post-Acute Sequelae of COVID-19 (PASC)

Abstract:

Background: Fibrin(ogen) amyloid microclots and platelet hyperactivation previously reported as a novel finding in South African patients with the coronavirus 2019 disease (COVID-19) and Long COVID/Post-Acute Sequelae of COVID-19 (PASC), might form a suitable set of foci for the clinical treatment of the symptoms of Long COVID/PASC. A Long COVID/PASC Registry was subsequently established as an online platform where patients can report Long COVID/PASC symptoms and previous comorbidities.

Methods: In this study, we report on the comorbidities and persistent symptoms, using data obtained from 845 South African Long COVID/PASC patients. By using a previously published scoring system for fibrin amyloid microclots and platelet pathology, we also analysed blood samples from 80 patients, and report the presence of significant fibrin amyloid microclots and platelet pathology in all cases.

Results: Hypertension, high cholesterol levels (dyslipidaemia), cardiovascular disease and type 2 diabetes mellitus (T2DM) were found to be the most important comorbidities. The gender balance (70% female) and the most commonly reported Long COVID/PASC symptoms (fatigue, brain fog, loss of concentration and forgetfulness, shortness of breath, as well as joint and muscle pains) were comparable to those reported elsewhere. These findings confirmed that our sample was not atypical. Microclot and platelet pathologies were associated with Long COVID/PASC symptoms that persisted after the recovery from acute COVID-19.

Conclusions: Fibrin amyloid microclots that block capillaries and inhibit the transport of O2 to tissues, accompanied by platelet hyperactivation, provide a ready explanation for the symptoms of Long COVID/PASC. Removal and reversal of these underlying endotheliopathies provide an important treatment option that urgently warrants controlled clinical studies to determine efficacy in patients with a diversity of comorbidities impacting on SARS-CoV-2 infection and COVID-19 severity. We suggest that our platelet and clotting grading system provides a simple and cost-effective diagnostic method for early detection of Long COVID/PASC as a major determinant of effective treatment, including those focusing on reducing clot burden and platelet hyperactivation.

Herpesvirus and neurological manifestations in patients with severe coronavirus disease

Abstract:

Background: Certain clinical manifestations of coronavirus disease (COVID-19) mimic those associated with human herpesvirus (HHV) infection. In this study, we estimated the prevalence of herpesvirus in patients with COVID-19 and determined if coinfection is associated with poorer outcomes and neurological symptoms.

Methods: We analyzed samples of 53 patients diagnosed with COVID-19. The samples were evaluated for the presence of alphaherpesviruses, betaherpesviruses, and gammaherpesviruses, and the viral loads were quantified using quantitative polymerase chain reaction (qPCR) method.

Results: Among the patients, in 79.2% had detection at least one type of herpesvirus. HHV-6 (47.2%), cytomegalovirus (43.3%), and HHV-7 (39.6%) showed the highest detection rates. Patients with a high severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) load were more likely to show herpes simplex virus 1 detection (p = 0.037). Among patients coinfected with SARS-CoV-2 and HHVs, 26.4% showed central nervous system-associated neurological symptoms and herpetic manifestations. A statistically significant association was observed between neurological changes and HHV-6 detection (p = 0.034).

Conclusions: The findings showed a high prevalence of herpesvirus in patients with COVID-19. Furthermore, even though SARS-CoV-2 and HHV coinfection was not associated with poorer outcomes, the findings demonstrated the association between neurological symptoms and HHV-6 detection.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is common in post-acute sequelae of SARS-CoV-2 infection (PASC): Results from a post-COVID-19 multidisciplinary clinic

Summary:

Background The global prevalence of PASC is estimated to be present in 0·43 and based on the WHO estimation of 470 million worldwide COVID-19 infections, corresponds to around 200 million people experiencing long COVID symptoms. Despite this, its clinical features are not well defined.

Methods We collected retrospective data from 140 patients with PASC in a post-COVID-19 clinic on demographics, risk factors, illness severity (graded as one-mild to five-severe), functional status, and 29 symptoms and principal component symptoms cluster analysis. The Institute of Medicine (IOM) 2015 criteria were used to determine the ME/CFS phenotype.

Findings The median age was 47 years, 59·0% were female; 49·3% White, 17·2% Hispanic, 14·9% Asian, and 6·7% Black. Only 12·7% required hospitalization. Seventy-two (53·5%) patients had no known comorbid conditions. Forty-five (33·9%) were significantly debilitated. The median duration of symptoms was 285·5 days, and the number of symptoms was 12. The most common symptoms were fatigue (86·5%), post-exertional malaise (82·8%), brain fog (81·2%), unrefreshing sleep (76·7%), and lethargy (74·6%). Forty-three percent fit the criteria for ME/CFS.

Interpretations Most PASC patients evaluated at our clinic had no comorbid condition and were not hospitalized for acute COVID-19. One-third of patients experienced a severe decline in their functional status. About 43% had the ME/CFS subtype.
