Post-infectious acute myocardial infarction following COVID-19 infection in a young patient

It is now widely known that COVID-19 can also cause various extrapulmonary manifestations. Possible mechanisms of cardiovascular damage include direct myocardial damage due to hypercoagulability caused by systemic inflammation, which may also lead to destabilisation of coronary plaques. We present a case of a 30-year-old young man following asymptomatic COVID-19 infection, who was admitted to the emergency room of the Grande Ospedale Metropolitano di Reggio Calabria, Italy, with typical chest pain. The patient had no cardiovascular disease, cardiovascular risk factors including no family history of cardiovascular disease. Urgent coronary angiography showed critical stenosis of the middle-proximal portion of the left anterior descending artery (80%) with ulcerated plaque appearance. Regardless of cardiovascular risk factors, our case report emphasises the need to determine COVID-19 status in all patients with acute myocardial infarction during this pandemic.Copyright © 2023, CKS.

COVID-19 and renal involvement: a prospective cohort study assessing the impact of mild SARS-CoV-2 infection on the kidney function of young healthy males.

PURPOSE: COVID-19 frequently affects the kidneys with symptoms ranging from mild proteinuria to progressive acute kidney injury. This prospective study aimed to assess the short- and long-term impact of asymptomatic and mild COVID-19 on the renal function of healthy young adults, and to determine the correlation between viral load and kidney function among these patients. METHODS: This was a prospective cohort study conducted over a period of 6 months. Patients were followed-up at baseline, and then after 3 and 6 months, respectively. Real-time PCR cycle threshold (CT) was used to determine the viral load and disease activity. Patients were classified into two groups with either asymptomatic COVID-19 or mild pneumonia. The assessment parameters were variables that could directly or indirectly relate to the renal function. RESULTS: A total of 48 patients were included and evaluated. The majority of patients (62.5%) had asymptomatic COVID-19 disease. Patients with mild pneumonia had significantly higher serum creatinine (SCr) at the time of COVID-19 diagnosis (beta = 12.836, 95% CI = 2.405-23.268, P = 0.019), after 3 months (beta = 14.345, 95% CI = 1.149-27.542, P = 0.035), and after 6 months (beta = 14.100, 95% CI = 0.730-27.470, P = 0.040) compared to asymptomatic patients. Mild pneumonia was also significantly associated with lower serum albumin level at the time of COVID-19 diagnosis (beta = - 6.317, 95% CI = - 9.448-- 3.185, P < 0.001). CONCLUSION: Mild COVID-19 is associated with mild renal involvement without AKI. Changes in the renal function appear to be related to reduced creatinine clearance and possible albumin leakage in the acute phase of the disease. The reduction in creatinine clearance is not predicted by viral load, and it appears to be a long-term effect of the disease that can last for at least 6 months.

Clinical characteristics of COVID-19 in young patients differ from middle-aged and elderly patients.

Introduction: Coronavirus disease-2019 (COVID-19) has spread worldwide. The study aimed to understand the clinical characteristics of young COVID-19 patients. Material and methods: Ninety patients with severe COVID-19 infection in western Chongqing were collected from 21 January to 14 March 2020. They were divided into 4 groups based on age: youth (< 39 years), middle-aged (39-48 years), middle-elderly aged (49-60 years), and elderly (> 60 years). The clinical symptoms, laboratory findings, imaging findings, and treatment effects were compared among the groups. Results: There were 22, 27, 19, and 22 cases in the youth, middle-aged, middle-elderly, and elderly groups, respectively. There were no significant differences with respect to gender or smoking status among the four groups. The clinical indicators of severe disease in the youth group were significantly different from the other three groups, and included the lymphocyte count (p < 0.001), C-reactive protein level (p = 0.03), interleukin-6 level (p = 0.01), chest computed tomography (CT) findings (p < 0.001), number of mild cases (p = 0.02), education level (p < 0.001), and CD4 + T lymphocyte level (p = 0.02) at the time of admission, and the pneumonia severity index (PSI) at the time of discharge (p < 0.001). The complications (p < 0.001) among the youth group were also significantly different from the other groups. Conclusions: Young patients have milder clinical manifestations, which may be related to higher education level, higher awareness and higher acceptance of the prevention and control of the COVID-19 epidemic, as well as their good immune function.

Can the Omicron variant of COVID-19 cause pneumonia in young patients without risk factors?

The Omicron variant (B.1.1.529) of coronavirus disease 2019 (COVID-19) has rapidly spread worldwide since December 2021. In daily medical practice, pneumonia does not often appear as a complication of the Omicron variant. We present a case of COVID-19 pneumonia by the Omicron variant in young patients without obvious risk factors.

Comparison of Clinical Characteristics and Outcomes of COVID-19 Between Young and Older Patients: A Multicenter, Retrospective Cohort Study.

Background Outcomes of coronavirus disease 2019 (COVID-19) have been reported to be different in the young and elderly populations. However, previous studies examining these characteristics and differences in outcomes between the two groups had a small sample size. Therefore, in this study, we evaluate the differences between young and elderly patients using a large multicenter dataset. Methodology We conducted a retrospective study of 1,116 consecutive COVID-19 patients admitted to two hospitals in southern California in the United States between March 2020 and March 2021. In this study, we categorized patients into two age groups: less than 65 years and 65 years and above. Finally, Kaplan-Meier and backward selection Cox multivariate regression analyses were done using mortality as the dependent variable. Results Our analysis showed increased survival in patients aged less than 65 years compared to those aged 65 years or above (p < 0.001). Furthermore, in patients aged 65 years and above, age (hazard ratio (HR) = 1.05; p < 0.001), C-reactive protein (CRP) (HR = 1.05; p < 0.001), and bradycardia (HR = 2.1; p < 0.001) were significantly associated with mortality. Similarly, CRP (HR 1.05; p = 0.02) was significantly associated with mortality in patients aged less than 65 years. However, contrary to many studies, being male (HR = 0.46; p = 0.002) was protective against mortality in patients aged less than 65 years. Conclusions Our study showed that the predictors of mortality in COVID-19 patients differed by age group. While age, CRP, and bradycardia were associated with mortality in those aged less than 65 years, only CRP was associated with mortality in those aged 65 years and above.

COVID-19 Related Fears of Patients Admitted to a Psychiatric Emergency Department during and Post-Lockdown in Switzerland: Preliminary Findings to Look Ahead for Tailored Preventive Mental Health Strategies.

Background and Objectives: While the impact on mental health of 2019 coronavirus (COVID-19) has been extensively documented, little is known about its influence on subjective fears. Here, we investigate the COVID-19 impact and its related restrictions on fears of patients admitted to a psychiatric Emergency Department (ED) during and post-lockdown. Materials and Methods: A retrospective study on 1477 consultations at the psychiatric ED of the University Hospital of Geneva (HUG) was performed using a mixed-methods analysis. The first analysis section was qualitative, aiming to explore the type of fears, while the second section statistically compared fears (i) during lockdown (16 March 2020-10 May 2020) and (ii) post-lockdown (11 May 2020-5 July 2020). Fears were also explored among different patient-age sub-groups. Results: 334 patients expressed one/more fears. Both in lockdown and post-lockdown, fears mostly pertained to "containment measures" (isolation, loneliness). When compared lockdown vs. post-lockdown, fears about "work status" (deteriorating, losing work) prevailed in lockdown (p = 0.029) while "hopelessness" (powerless feeling, inability to find solutions) in post-lockdown (p = 0.001). "Self around COVID-19" (dying, getting sick) fear was relatively more frequent in youth (p = 0.039), while "hopelessness" in the elderly (p < 0.001). Conclusions: Collectively, these findings highlight that lockdown/post-lockdown periods generated temporally and demographically distinct COVID-19 related fears patterns, with special regard to youth and elderly, two particularly vulnerable populations when faced with sudden and unexpected dramatic events. For this reason, the particular ED "front-line service" status makes it a privileged observatory that can provide novel insights. From a mental health perspective, these latter can be translated into pragmatic, more personalized prevention strategies to reinforce specific resilience resources and mitigate the current and long-term pandemic's impact.

Asymptomatic COVID-19 and ST-elevation myocardial infarction in young adults: lessons learned from two similar cases.

We present two cases of acute myocardial infarction in young patients with asymptomatic COVID-19 infection and ST-elevation myocardial infarction (STEMI), complicated by severe acute heart failure and ventricular fibrillation, resulting cardiopulmonary resuscitation and mechanical ventilatory support. Urgent primary percutaneous coronary intervention with further complex treatment was effective in both cases with critical cardiovascular state and co-morbid COVID-19 infection. This report illustrates the challenges in clinical severity of STEMI with COVID-19 infection, despite of young age and absence of clinical symptoms and chronic co-morbidities. STEMI patients with even asymptomatic COVID-19 infection may be presented with significantly higher rates of severe acute heart failure.

Predictors of mortality for hospitalized young adults aged less than 60 years old with severe COVID-19: a retrospective study.

BACKGROUND: To analyze the clinical characteristics and predictors for mortality of adult younger than 60 years old with severe coronavirus disease 2019 (COVID-19). METHODS: We retrospectively retrieved data for 152 severe inpatients with COVID-19 including 60 young patients in the Eastern Campus of Wuhan University affiliated Renmin Hospital in Wuhan, China, from January 31, 2020 to February 20, 2020. We recorded and analyzed patients' demographic, clinical, laboratory, and chest CT findings, treatment and outcomes data. RESULTS: Of those 60 severe young patients, 15 (25%) were died. Male was more predominant in deceased young patients (12, 80%) than that in recovered young patients (22, 49%). Hypertension was more common among deceased young patients (8, 53%) than that in recovered young patients (7, 16%). Compared with the recovered young patients, more deceased young patients presented with sputum (11, 73%), dyspnea (12, 80%) and fatigue (13, 87%). Only sputum, PSI and neutrophil counts were remained as independent predictors of death in a multivariate logistic regression model. Among ARDS patients, the recovered were administrated with corticosteroid earlier and anticoagulation. The addition of neutrophil counts >6.3×109/L to the SMART-COP score resulted in improved area under the curves. CONCLUSIONS: Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection in young deceased patients appears to cause exuberant inflammatory responses, leading to compromised oxygen exchange, coagulation and multi-organ dysfunction. In addition, young patients with ARDS could benefit from adjuvant early corticosteroid and anticoagulation therapy. The expanded SMART-COP could predict the fatal outcomes with optimal efficiency.

Comparison of COVID-19 disease between young and elderly patients: Hidden viral shedding of COVID-19.

OBJECTIVES: The symptoms of Coronavirus disease 2019 (COVID-19) vary among patients. The aim of this study was to investigate the clinical manifestation and disease duration in young versus elderly patients. METHODS: We retrospectively analyzed 187 patients (87 elderly and 100 young patients) with confirmed COVID-19. The clinical characteristics and chest computed tomography (CT) extent as defined by a score were compared between the two groups. RESULTS: The numbers of asymptomatic cases and severe cases were significantly higher in the elderly group (elderly group vs. young group; asymptomatic cases, 31 [35.6%] vs. 10 [10%], p < 0.0001; severe cases, 25 [28.7%] vs. 8 [8.0%], p = 0.0002). The proportion of asymptomatic patients and severe patients increased across the 10-year age groups. There was no significant difference in the total CT score and number of abnormal cases. A significant positive correlation between the disease duration and patient age was observed in asymptomatic patients (ρ = 0.4570, 95% CI 0.1198-0.6491, p = 0.0034). CONCLUSIONS: Although the extent of lung involvement did not have a significant difference between the young and elderly patients, elderly patients were more likely to have severe clinical manifestations. Elderly patients were also more likely to be asymptomatic and a source of COVID-19 viral shedding.
