Case report: A case of Acute Macular Neuroretinopathy secondary to Influenza A virus during Long COVID

Abstract:

Ocular abnormalities have been reported in association with viral infections, including Long COVID, a debilitating illness caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This report presents a case of a female patient diagnosed with Acute Macular Neuroretinopathy (AMN) following an Influenza A virus infection during Long COVID who experienced severe inflammation symptoms and ocular complications. We hypothesize that the rare occurrence of AMN in this patient could be associated with the immune storm secondary to the viral infection during Long COVID.

Spinal cord infarction attributed to SARS-CoV-2, with post-acute sequelae of COVID-19: A case report

Abstract:

Background: While stroke and lower extremity venous thromboemboli have been commonly reported following acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), spinal cord infarction or ischemia has been extremely rare. Findings of long coronavirus disease (COVID) in this select population have not been studied.

Case summary: We present the case of a 70-year-old female with sudden onset of trunk and lower extremity sensorimotor loss due to spinal cord infarction, attributed to acute infection with SARS-CoV-2. Diagnostic work up confirmed a T3 complete (ASIA impairment Scale A) paraplegia resulting from a thrombotic infarct. Her reported myalgias, neuropathic pain, spasticity, bladder spasms, and urinary tract infections exceeded the frequency and severity of many spinal cord injury (SCI) individuals of similar age and degree of neurologic impairment.

In her first year after contracting COVID-19, she underwent 2 separate inpatient rehabilitation courses, but also required acute hospitalization 6 additional times for subsequent infections or uncontrolled pain. Yet other complications of complete non-traumatic SCI (NTSCI), including neurogenic bowel and temperature hypersensitivity, were mild, and pressure injuries were absent. She has now transitioned from the acute to chronic phase of spinal cord injury care, with subsequent development of post-acute sequelae of SARS-CoV-2 infection (PASC).

Conclusion: This individual experienced significant challenges with the combined effects of acute T3 NTSCI and acute COVID-19, with subsequent progression to PASC.

Long post-COVID-19 postural tachycardia syndrome (PoTS): A novel case

Introduction

There are no established ESC/NICE guidelines for early risk preventive strategies for postural tachycardia syndrome following long COVID-19 infection.1 A lack of early multi-disciplinary input and risk preventive strategies for this population has led to significant cardiovascular implications such as postural tachycardia and syncope, contributing to long-term emotional distress in recent years.1,2

Case presentation

A previously fit 36-year-old woman was admitted to our tertiary centre with a 3-month history of palpitations, chest discomfort and dizziness that were prominent while standing and improved with recumbence. She also described her palpitations, which were sometimes associated with missed beats, and it took longer than expected (at least 10–15 minutes) to settle after postural changes. These symptoms had all significantly impacted on her daily physical activities and caused emotional distress. She gave a history of serious COVID-19 infection requiring hospital admission 4 months previously. She reported that she was treated as having COVID pneumonitis requiring antibiotics, oxygen and steroids but no intensive care admission. Since then, she had noticed frequent episodes of postural palpitations with chest tightness, which had led to her recent admission. On examination, she has normal cardiorespiratory findings and no features of systemic involvement. She has no other significant family and social history with regard to other cardiovascular risk factors.

Initially, she was enrolled into a postural assessment of resting heart rate and blood pressure when she had her symptoms of palpitations. Her resting heart rate was 100 bpm while standing. Interestingly, her resting heart rate returned to normal (54 bpm) after 10 minutes of supine position. Her blood pressure 100/60 while supine and 98/74 when standing, which had ruled out postural hypotension. Following this, an active stand test (tilt table test) was administered on subsequent day. Her electrocardiogram (Fig 1) revealed sinus tachycardia when she had episodes of palpitation but it returned to normal sinus rhythm with heart rate 60 bpm after 10 minutes of recumbent position from standing. All blood investigations, including full blood count, troponins, inflammatory markers and renal profile including electrolytes, revealed normal findings, which had ruled out other differentials.

Discussion

As a whole, these postural assessments (Tables 1 and 2) had met the criteria for definition of postural tachycardia syndrome2 (typical symptoms with significant heart rate increase of >30 beats per minute within 10 minutes of standing and without orthostatic hypotension). To support this, her echocardiogram showed no significant signs of structural heart disease and satisfactory blood investigations. Given her timing of her postural cardiovascular symptoms related to post-COVID-19 infection and criteria being met for postural assessment, she was finally diagnosed as having postural tachycardia syndrome as a cause for long-COVID-19 symptoms.3 Overall, she was advised to increase her fluid intake to 3 litres per day with increased salt intake, to use lower body compression garments and to take non-upright exercise.1 This was followed by early multidisciplinary team (MDT) input, including the recommendation of webinars on living with POTS and psychological counselling.2

Conclusion

It is well-recognised in recent literature that a diagnosis of PoTS post-COVID infection is easily overlooked as it does not associate with structural or arrhythmic heart disease and its specific aetiology is poorly defined apart from autonomic dysregulation.1,3 Therefore, more epidemiology study and detailed prospective research in long-COVID-19 patients are crucial for early recognition of this syndrome and long-term risk prevention.1,2

Single-Cell RNA Sequencing Reveals Alterations in Patient Immune Cells with Pulmonary Long COVID-19 Complications

Abstract:

Since the emergence of the COVID-19 pandemic, the effects of SARS-CoV-2 have been extensively researched. While much is already known about the acute phase of the infection, increasing attention has turned to the prolonged symptoms experienced by a subset of individuals, commonly referred to as long COVID-19 patients. This study aims to delve deeper into the immune landscape of patients with prolonged symptoms by implementing single-cell mRNA analysis.
A 71-year-old COVID-19 patient presenting with persistent viral pneumonia was recruited, and peripheral blood samples were taken at 3 and 2 years post-acute infection onset. Patients and control peripheral blood mononuclear cells (PBMCs) were isolated and single-cell sequenced. Immune cell population identification was carried out using the ScType script.
Three months post-COVID-19 patients’ PBMCs contained a significantly larger immature neutrophil population compared to 2-year and control samples. However, the neutrophil balance shifted towards a more mature profile after 18 months. In addition, a notable increase in the CD8+ NKT-like cells could be observed in the 3-month patient sample as compared to the later one and control. The subsequent change in these cell populations over time may be an indicator of an ongoing failure to clear the SARS-CoV-2 infection and, thus, lead to chronic COVID-19 complications.

Electroencephalographic Abnormalities in a Patient Suffering from Long-Term Neuropsychological Complications following SARS-CoV-2 Infection

Abstract:

Introduction: Emotional apathy has recently been identified as a common symptom of long COVID. While recent meta-analyses have demonstrated generalized EEG slowing with the emergence of delta rhythms in patients hospitalized for severe SARS-CoV-2 infection, no EEG study or dopamine transporter scintigraphy (DaTSCAN) has been performed in patients with long COVID presenting with apathy. The objective of this case report was to explore the pathophysiology of neuropsychological symptoms in long COVID.

Case presentation: A 47-year-old patient who developed a long COVID with prominent apathy following an initially clinically mild SARS-CoV-2 infection underwent neuropsychological assessment, cerebral MRI, DaTSCAN, and resting-state high-density EEG 7 months after SARS-CoV-2 infection. The EEG data were compared to those of 21 healthy participants. The patient presented with apathy, cognitive difficulties with dysexecutive syndrome, moderate attentional and verbal episodic memory disturbances, and resolution of premorbid mild gaming disorder, mild mood disturbances, and sleep disturbances. His MRI and DaTSCAN were unremarkable. EEG revealed a complex pattern of oscillatory abnormalities compared to the control group, with a strong increase in whole-scalp delta and beta band activity, as well as a decrease in alpha band activity. Overall, these effects were more prominent in the frontal-central-temporal region.

Conclusion: These results suggest widespread changes in EEG oscillatory patterns in a patient with long COVID characterized by neuropsychological complications with prominent apathy. Despite the inherent limitations of a case report, these results suggest dysfunction in the cortical networks involved in motivation and emotion.

Long COVID with Persistent High Fever as the Main Manifestation: A Case Report

Abstract:

Background COVID-19, caused by SARS-CoV-2, has had a profound global impact, affecting millions of people. Long COVID, also known as Post-Acute Sequelae of SARS-CoV-2 infection (PASC), is characterized by persistent symptoms following acute COVID-19, affecting more than 65 million individuals worldwide. In this case report, we highlight a rare occurrence of Long COVID with high fever, underlining its clinical significance.

Case presentation A 34-year-old female with a 24-day history of recurrent fever, initially reaching 37.5°C, accompanied by headache, fatigue, and joint pain, was admitted with a diagnosis of “fever of unknown origin.” Extensive testing, including negative nucleic acid tests for the novel coronavirus, negative blood cultures, and normal imaging, prompted the use of blood Next-Generation Sequencing (NGS) to detect COVID-19. Despite repeated negative nucleic acid tests, elevated COVID-19 antibody levels indicated the presence of long COVID. Methylprednisolone was administered, resulting in the resolution of symptoms. The patient remained asymptomatic during the follow-up.

Pediatric de novo movement disorders and ataxia in the context of SARS-CoV-2

Abstract:

Objective: In the fourth year of the COVID-19 pandemic, mortality rates decreased, but the risk of neuropsychiatric disorders remained the same, with a prevalence of 3.8% of pediatric cases, including movement disorders (MD) and ataxia.

Methods: In this study, we report on a 10-year-old girl with hemichorea after SARS-CoV-2 infection and immunostained murine brain with patient CSF to identify intrathecal antibodies. Additionally, we conducted a scoping review of children with MD and ataxia after SARS-CoV-2 infection.

Results: We detected antibodies in the patient’s CSF binding unknown antigens in murine basal ganglia. The child received immunosuppression and recovered completely. In a scoping review, we identified further 32 children with de novo MD or ataxia after COVID-19. While in a minority of cases, MD or ataxia were a symptom of known clinical entities (e.g. ADEM, Sydenham’s chorea), in most children, the etiology was suspected to be of autoimmune origin without further assigned diagnosis. (i) Children either presented with ataxia (79%), but different from the well-known postinfectious acute cerebellar ataxia (older age, less favorable outcome, or (ii) had hypo-/hyperkinetic MD (21%), which were choreatic in most cases. Besides 14% of spontaneous recovery, immunosuppression was necessary in 79%. Approximately one third of children only partially recovered.

Conclusions: Infection with SARS-CoV-2 can trigger de novo MD in children. Most patients showed COVID-19-associated-ataxia and fewer-chorea. Our data suggest that patients benefit from immunosuppression, especially steroids. Despite treatment, one third of patients recovered only partially, which makes up an increasing cohort with neurological sequelae.

Long COVID-19 and Insulin Autoimmune Syndrome: A Case Report

Abstract:

Purpose: To describe a case report of a patient with symptoms associated with metabolic alterations 1 month after having COVID-19.

Methods: Laboratory tests, clinical evaluations, and body composition assessments were performed by specialists.

Findings: The patient presented excessive sweating, hot flashes, dizziness, blurred vision, and seizure. Laboratory tests indicated low glucose levels after convulsions (50, 42.7, and 55 mg/dL), high insulin levels (basal, 638 µIU/mL; 2-hour, >1000 µU/mL), and positivity for anti-insulin antibodies. The patient was diagnosed with insulin autoimmune syndrome. Treatment with azathioprine and nutritional recommendations improved remission.

Implications: SARS-CoV-2 infection or vaccination might induce insulin tolerance failure.
