Associations between physical activity prior to infection and COVID-19 disease severity and symptoms: results from the prospective Predi-COVID cohort study.

OBJECTIVE: To investigate if the physical activity (PA) prior to infection is associated with the severity of the disease in patients positively tested for COVID-19, as well as with the most common symptoms. DESIGN: A cross-sectional study using baseline data from a prospective, hybrid cohort study (Predi-COVID) in Luxembourg. Data were collected from May 2020 to June 2021. SETTING: Real-life setting (at home) and hospitalised patients. PARTICIPANTS: All volunteers aged >18 years with confirmed SARS-CoV-2 infection, as determined by reverse transcription-PCR, and having completed the PA questionnaire (n=452). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was disease severity (asymptomatic, mild illness and moderate illness). The secondary outcomes were self-reported symptoms. RESULTS: From the 452 patients included, 216 (48%) were female, the median (IQR) age was 42 (31-51) years, 59 (13%) were classified as asymptomatic, 287 (63%) as mild illness and 106 (24%) as moderate illness. The most prevalent symptoms were fatigue (n=294; 65%), headache (n=281; 62%) and dry cough (n=241; 53%). After adjustment, the highest PA level was associated with a lower risk of moderate illness (OR 0.37; 95% CI 0.14 to 0.98, p=0.045), fatigue (OR 0.54; 95% CI 0.30 to 0.97, p=0.040), dry cough (OR 0.55; 95% CI 0.32 to 0.96, p=0.034) and chest pain (OR 0.32; 95% CI 0.14 to 0.77, p=0.010). CONCLUSIONS: PA before COVID-19 infection was associated with a reduced risk of moderate illness severity and a reduced risk of experiencing fatigue, dry cough and chest pain, suggesting that engaging in PA may be an effective approach to minimise the severity of COVID-19.

Prevalence of Post-COVID-19 Cough One Year After SARS-CoV-2 Infection: A Multicenter Study.

This multicenter study presents prevalence data and associated risk factors of post-COVID-19 cough one year after hospital discharge in COVID-19 survivors. Individuals recovered from COVID-19 at three public hospitals in Madrid (Spain) were scheduled for a telephonic interview. They were systematically asked about the presence of respiratory symptoms, e.g., fatigue, dyspnea, chest pain, and cough after hospital discharge. Clinical and hospitalization data were collected from hospital records. Overall, 1,950 patients (47% women, mean age:61, SD:16 years) were assessed at 11.2 months (SD 0.5) after hospital discharge. Just 367 (18.8%) were completely free of any respiratory post-COVID -19 symptom. The prevalence of long-term cough, chest pain, dyspnea, and fatigue was 2.5%, 6.5%, 23.3%, and 61.2%, respectively. Clinical and hospitalization factors were not associated with long-term post-COVID-19 cough. In conclusion, the prevalence of post-COVID-19 cough one year after SARS-CoV-2 infection was 2.5% in subjects who had survived hospitalization for COVID-19. No clear risk factor associated to long-term post-COVID-19 cough was identified.

'Long COVID': persistent COVID-19 symptoms in survivors managed in Lagos State, Nigeria.

BACKGROUND: Coronavirus disease once thought to be a respiratory infection is now recognised as a multi-system disease affecting the respiratory, cardiovascular, gastrointestinal, neurological, immune, and hematopoietic systems. An emerging body of evidence suggests the persistence of COVID-19 symptoms of varying patterns among some survivors. This study aimed to describe persistent symptoms in COVID-19 survivors and investigate possible risk factors for these persistent symptoms. METHODS: The study used a retrospective study design. The study population comprised of discharged COVID-19 patients. Demographic information, days since discharge, comorbidities, and persistent COVID-19 like symptoms were assessed in patients attending the COVID-19 outpatient clinic in Lagos State. Statistical analysis was done using STATA 15.0 software (StataCorp Texas) with significance placed at p-value < 0.05. RESULTS: A total of 274 patients were enrolled in the study. A majority were within the age group > 35 to ≤49 years (38.3%), and male (66.1%). More than one-third (40.9%) had persistent COVID-19 symptoms after discharge, and 19.7% had more than three persistent COVID-like symptoms. The most persistent COVID-like symptoms experienced were easy fatigability (12.8%), headaches (12.8%), and chest pain (9.8%). Symptomatic COVID-19 disease with moderate severity compared to mild severity was a predictor of persistent COVID-like symptoms after discharge (p < 0.05). CONCLUSION: Findings from this study suggests that patients who recovered from COVID-19 disease may still experience COVID-19 like symptoms, particularly fatigue and headaches. Therefore, careful monitoring should be in place after discharge to help mitigate the effects of these symptoms and improve the quality of life of COVID-19 survivors.

COVID-19 cardiac injury and the use of colchicine.

We report a case of cardiac injury in a 46-year-old man affected by COVID-19. The patient presented with shortness of breath and fever. ECG revealed sinus tachycardia with ventricular extrasystoles and T-wave inversion in anterior leads. Troponin T and N-terminal pro B-type natriuretic peptide were elevated. Transthoracic echocardiography showed severely reduced systolic function with an estimated left ventricle ejection fraction of 30%. A nasopharingeal swab was positive for SARS-CoV-2. On day 6, 11 days after onset of symptoms, the patient deteriorated clinically with new chest pain and type 1 respiratory failure. Treatment with colchicine 0.5 mg 8-hourly resulted in rapid clinical resolution. This case report highlights how cardiac injury can dominate the clinical picture in COVID-19 infection. The role of colchicine therapy should be further studied to determine its usefulness in reducing myocardial and possibly lung parenchymal inflammatory responses.

Symptomatic relapse and long-term sequelae of COVID-19 in a previously healthy 30-year-old man.

Much has been reported on the clinical course of severe COVID-19, but less is known about the natural history and sequalae of mildly symptomatic cases and the prospects of reinfection or recurrence of symptoms. We report a case of a patient with mildly symptomatic PCR-confirmed COVID-19 who, after being symptom-free for 2 weeks, redeveloped symptoms and was found to be PCR-positive again >4 weeks from original testing. Surprisingly, IgG and IgM antibody testing was negative 2 months after reinfection. Although no negative testing was performed between the two symptomatic bouts, this case raises the possibility of reinfection after controlling the virus and highlights the long period with which a patient can shed virus and experience symptoms after initial infection. Characterising variations in clinical symptoms and length of viral shedding after improvement is essential for informing recommendations on patients safely resuming contact with others.

"I Was Wrong": A Surgeon's First-Person Account of His COVID-19 Illness.

A surgeon failed to heed his own misgivings on taking a family vacation cruise. Despite scrupulous hand-washing and antiseptic precautions with anything within reach, he contracts COVID-19. His anxiety increased as his condition became increasingly serious: uncontrollable dry coughing spells, spiking fevers, and his worst symptom, progressive dyspnea and chest pain. From what he knew about the disease, he feared admission to the intensive care unit, a step that portended a significantly worse prognosis. After a week-and-a-half of illness, misery, and fear, he began to improve: first, his fevers diminished, breathing came more easily, and coughing spells occurred less frequently, if still unpredictably. Now with his strength slowly returning, he contemplated returning to work but was frustrated when tests showed he was still shedding active virions. Under quarantine and with time to reflect, he cautions against complacency with regard to the infectiousness of COVID-19. His own denial led to the loss of his health and livelihood. At home but still separated from his wife and children in a basement bedroom, the bittersweet circumstances of his reunion with them is a reminder of the preciousness of life and love of family.

Acute myocarditis associated with COVID-19 infection.

We present the case of a 20-year-old male patient without previous history of cardiovascular disease who was admitted to our hospital with a new onset febrile sensation and chest pain. Chest computed tomography revealed a subpleural consolidation with a halo of ground-glass opacification. Blood tests revealed elevated levels of markers of myocyte necrosis (troponin I and creatine kinase-MB). Nasopharyngeal swab was positive for COVID-19. Cardiac MRI showed myocardial edema and late gadolinium enhancement compatible with myocarditis associated with COVID-19 infection. This case showed that acute myocarditis can be the initial presentation of patients with COVID-19 infection.

Atypical presentation of COVID-19 in a patient with type 2 diabetes at an urban primary care facility in Accra, Ghana.

This is a case report of a 55-year-old man with Type 2 Diabetes Mellitus who presented with progressive breathlessness, chest pain and hyperglycaemia. An initial impression of a chest infection was made. Management was initiated with antibiotics, but this was unsuccessful, and he continued to desaturate. A screen for Coronavirus Disease of 2019 (COVID-19) returned positive. There was no prodrome of fever or flu-like illness or known contact with a patient known to have COVID-19. This case is instructive as he didn't fit the typical case definition for suspected COVID-19. There is significant community spread in Ghana, therefore COVID-19 should be a differential diagnosis in patients who present with hyperglycaemia and respiratory symptoms in the absence of a febrile illness. Primary care doctors must have a high index of suspicion in cases of significant hyperglycaemia and inability to maintain oxygen saturation. Patients known to have diabetes and those not known to have diabetes may develop hyperglycaemia subsequent to COVID-19. A high index of suspicion is crucial for early identification, notification for testing, isolation, treatment, contact tracing and possible referral or coordination of care with other specialists. Early identification will protect healthcare workers and patients alike from cross-infection.

Spontaneous splenic rupture in a patient with infectious mononucleosis.

We present a case of spontaneous, atraumatic splenic rupture secondary to Epstein-Barr virus (EBV) infection, in a young, female patient. Splenic rupture is a rare complication of EBV infection, but is associated with the highest mortality. Additionally, this case illustrates the diagnostic challenge in a patient presenting in atypical manner, with only left-sided pleuritic chest pain, and lacking any of the classical tonsillitis symptoms associated with EBV infection.

Young patient with hantavirus-induced myocarditis detected by comprehensive cardiac magnetic resonance assessment.

BACKGROUND: We report a case of hantavirus-induced myocarditis in a young adult. Hantavirus showed a rapid increase of infections in the year 2017. Only scarce data is available about potential myocardial involvement in hantavirus infections. With ECG and echocardiography providing often inconclusive results, a multiparametric cardiac magnetic resonance protocol with distinct myocardial tissue characterization seems to be the adequate tool for detecting even slight myocardial alterations. CASE PRESENTATION: This case started with the presentation of young adult suffering from headache and abdominal pain. Thrombocytes were decreased, creatinine was elevated, and there was massive proteinuria. Puumala virus IgG ELISA turned out to be positive, and specific antibodies (IgG and IgM) could be detected in the serum, and confirmed by immunoassay. The patient was admitted to the nephrology department for supportive therapy. Few days later, the patient reported chest pain and dyspnea. High sensitivity troponin I rose up to 0.32 µg/l (normal range below 0.04 µg/l) with an increase of the creatinkinase to 319 U/l (normal max. 190 U/l), no dynamic ECG changes could be observed. Echocardiography revealed a normal left ventricular function without regional wall motion abnormalities, no pericardial effusion or valve abnormalities, coronary artery disease could be excluded by computed tomography. A multiparametric cardiac magnetic resonance protocol including recent mapping techniques confirmed myocardial involvement induced by acute hantavirus infection. In the next few weeks, the patient's state of health rapidly improved and symptoms of chest pain and dyspnea disappeared. Follow up multiparametric CMR exam showed substantial decrease of the previously observed myocardial alterations during acute hantavirus infection suggesting myocardial healing. CONCLUSIONS: This case demonstrates that a CMR protocol including recent mapping techniques and established late gadolinium enhancement technique is an adequate non-invasive tool for both 1) initial detection, and 2) follow up of patients with hantavirus-induced myocarditis, which might be more common than previously known.

A Case Report of Parvovirus B19 Infection in a Renal Allograft.

Parvovirus B19 infection is undiagnosed in recipients undergoing solid organ transplantation. It is usually responsible for unexplained acute and chronic red blood cell aplasia that does not respond to erythropoietin therapy. Cases of parvovirus B19 infection associated with pancytopenia, solid organ dysfunction, and allograft rejection have been described in the literature. The deterioration of the immune system as a result of severe immunotherapy favors the reactivation of a previous infection or the acquisition of a new one. We present a case of a 32-year-old woman with a 1-year history of renal allograft transplant and previous cytomegalovirus (CMV) infection who presented with chest pain, polyarthritis, pancytopenia, and renal dysfunction. A serum sample using polymerase chain reaction showed a parvovirus titer of 13.8 trillion IU/mL and a CMV titer of 800 IU/mL. The renal biopsy revealed nucleomegaly with focal viral inclusions, along with changes associated with immunotherapy toxicity. Electron microscopy demonstrated capillary and tubular epithelial cells with "viral factories," thereby confirming the diagnosis. Thus, screening for parvovirus B19 is advised in high-risk patients who present with refractory anemia to avoid the complications of a chronic infection associated with the fatal rejection of the transplanted organ.

Cytomegalovirus esophagitis in an immunocompetent patient: case report.

Cytomegalovirus (CMV) esophagitis is well-documented in immunocompromised patients. A few studies have described CMV infection in immunocompetent patients diagnosed with a critical illness. However, CMV esophagitis has rarely been documented in immunocompetent hosts. We report a case of CMV esophagitis in an immunocompetent patient who presented with chest pain and dysphagia that was successfully resolved with ganciclovir treatment. Our case supports observations that CMV esophagitis can cause significant morbidity, regardless of immune system status.

Acute right ventricular myocarditis presenting with chest pain and syncope.

Myocarditis is assumed to involve both ventricles equally. Right ventricular predominant involvement is rarely described. A case of acute viral right ventricular myocarditis presenting with chest pain and syncope, grade 3 atrioventricular block, right ventricular dilatation and free wall hypokinesia is reported. Cardiac MRI showed late enhancement of the right ventricular free wall without involvement of the left ventricle. Anti-Coxsackie A9 virus neutralising IgM-type antibodies titre was elevated. This case emphasises that manifestations of myocarditis can be limited to the right ventricle and should be considered in the differential diagnosis of right ventricular enlargement.

Varicella myopericarditis mimicking myocardial infarction in a 17-year-old boy.

Varicella (chickenpox), a common childhood infection caused by the varicella-zoster virus, is self-limiting and usually benign. Although atypical manifestations of the virus are occasionally seen, it rarely presents with cardiovascular sequelae. Cardiovascular complications of varicella can include pericarditis, myocarditis, or endocarditis. Herein, we report the case of a 17-year-old boy who had varicella infection and severe chest pain. Examination revealed atypical electrocardiographic findings of pericarditis and remarkably elevated cardiac biomarker levels: peak cardiac troponin I, 37.2 ng/mL; total creatine kinase, 1,209 U/L; and creatine kinase-MB fraction, 133.6 ng/mL. After results of coronary angiography reliably excluded ischemia and myocardial infarction, the diagnosis was varicella myopericarditis. The patient was placed on a medical regimen during and after 5 days of hospitalization. In 2 weeks, he was asymptomatic, and at 6 months, he was doing well and had normal electrocardiographic and echocardiographic results.To our knowledge, cardiac enzyme elevations to these levels have not been reported in cases of cardiovascular sequelae of varicella. We discuss the diagnostic challenges of this atypical case and suggest that clinicians be aware that varicella disease is most often, but not always, benign.

Herpes zoster in older adults.

Herpes zoster (HZ) is a common condition among older adults, manifested by pain and the classic presentation of a unilateral rash that follows a dermatomal distribution and does not cross the midline of the body. It is caused by reactivation of the virus that caused chickenpox during an earlier infection. In many cases, acute HZ is followed by a severe and disabling complication known as postherpetic neuralgia (PHN), characterized by pain that persists for months or even years after the HZ rash heals. Using an individual example, this article provides information on the clinical manifestations, evidence-based treatment recommendations for, and prevention of HZ and PHN through use of the zoster vaccine Zostavax, licensed in the United States in 2006.
