Multisystem Inflammatory Syndrome in Adults Associated With COVID-19: A Case Series on the Importance of Early Diagnosis and Corticosteroid Therapy in Prognosis.

Multisystem inflammatory syndrome in adults (MIS-A) is a rare condition that can occur after an adult has been infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It can occur anywhere between two and 12 weeks after the beginning of acute coronavirus disease 2019 (COVID-19) infection and is characterized by extrapulmonary multiorgan failure. It is primarily seen in young and previously healthy individuals. The exact prevalence of MIS-A is unclear. It is likely underdiagnosed due to overlapping symptoms with severe COVID-19 and difficulty in identifying the syndrome without a preceding COVID-19 infection. The pathogenesis of MIS-A is also largely unknown but is likely caused by an immune response that is dysregulated or antibody-mediated. Treatment primarily involves corticosteroids, but severe cases may require intravenous immune globulin (IVIG). The timing of starting corticosteroid therapy is crucial, as delays can result in increased complications and a longer hospital stay.

Presumptive Rhino-Orbital Mucormycosis Secondary to Corticosteroid Therapy in a Diabetic Patient With COVID-19 Infection.

The coronavirus disease 2019 (COVID-19) pandemic has led to the widespread use of steroids as a life-saving measure. In patients with preexisting diabetes, the therapeutic use of steroids coupled with poorly controlled sugar has led to a surge of mucormycosis. We report a rare case of orbital apex syndrome secondary to mucormycosis post-COVID-19. A 43-year-old female with poorly controlled diabetes mellitus presented with right eye complete ptosis one week post-recovery from COVID-19 infection. During COVID-19 hospitalization, she received a course of dexamethasone. The visual acuity of the right eye was 6/60. She had complete ophthalmoplegia and diplopia in all gazes. There was a positive relative afferent pupillary defect (RAPD) and reduced optic nerve function test in the right eye. MRI showed right ethmoid sinusitis with possible extension to the right orbit and the presence of right perineural optic nerve enhancement. The nasal scope revealed fungal-like thick mucopurulent discharge at the middle meatus. She was clinically diagnosed with rhino-orbital mucormycosis and was started on antifungal for six weeks. Her overall condition improved with 6/6 visual acuity and minimum residual ophthalmoplegia. In conclusion, corticosteroid treatment for COVID-19 infection in diabetic patients causes poor glycemic control and immunosuppression that can lead to secondary infections such as rhino-orbital mucormycosis.

Black fungus outbreak in India - A direct consequence of COVID-19 surge: A myth or reality.

The deadly second wave of COVID-19 has seen an unprecedented surge in mucormycosis associated mortality in India, overwhelming the heath authorities with challenges beyond measure. Also known as black fungus, this life-threatening fungal infection usually manifests in the nose, spreads to the eyes, and in some cases also to the brain. Immune suppression, pre-existing conditions, prolonged and indiscriminate use of steroids, and unhygienic environments are some of the widely recognized risk factors for contracting black fungus in individuals recovered from COVID-19. However, diagnosis of the infection remains insufficient due to the lack a holistic understanding of the possible risks, symptoms, and exposure pathways and therefore no definite protocol exists for managing this fatal infection. Here, we synthesize the current state of knowledge on black fungus outbreak in India and identify key gaps in its understanding with respect to potential risk factors leading to the widespread infection. We looked at 3354 black fungus cases in India, enlisting ailment history (particularly diabetes) and steroid usage in COVID-19 patients as the key factors responsible for exacerbating risks associated with the disease. However, we also press on the possibilities that other less studied non-traditional risk factors may also have a role in causing the infection. Black fungus is therefore a reality of COVID-19, with or without diabetes or steroid use needs to be investigated. We believe such a review is imperative for making informed decisions specially around timely diagnosis and channelizing efforts in controlling the spread of COVID-19 associated mucormycosis.

Corticosteroid treatment in severe patients with SARS-CoV-2 and chronic HBV co-infection: a retrospective multicenter study.

BACKGROUND: The impact of corticosteroids on patients with severe coronavirus disease 2019 (COVID-19)/chronic hepatitis B virus (HBV) co-infection is currently unknown. We aimed to investigate the association of corticosteroids on these patients. METHODS: This retrospective multicenter study screened 5447 confirmed COVID-19 patients hospitalized between Jan 1, 2020 to Apr 18, 2020 in seven centers in China, where the prevalence of chronic HBV infection is moderate to high. Severe patients who had chronic HBV and acute SARS-cov-2 infection were potentially eligible. The diagnosis of chronic HBV infection was based on positive testing for hepatitis B surface antigen (HBsAg) or HBV DNA during hospitalization and a medical history of chronic HBV infection. Severe patients (meeting one of following criteria: respiratory rate > 30 breaths/min; severe respiratory distress; or SpO2 ≤ 93% on room air; or oxygen index < 300 mmHg) with COVID-19/HBV co-infection were identified. The bias of confounding variables on corticosteroids effects was minimized using multivariable logistic regression model and inverse probability of treatment weighting (IPTW) based on propensity score. RESULTS: The prevalence of HBV co-infection in COVID-19 patients was 4.1%. There were 105 patients with severe COVID-19/HBV co-infections (median age 62 years, 57.1% male). Fifty-five patients received corticosteroid treatment and 50 patients did not. In the multivariable analysis, corticosteroid therapy (OR, 6.32, 95% CI 1.17-34.24, P = 0.033) was identified as an independent risk factor for 28-day mortality. With IPTW analysis, corticosteroid treatment was associated with delayed SARS-CoV-2 viral RNA clearance (OR, 2.95, 95% CI 1.63-5.32, P < 0.001), increased risk of 28-day and in-hospital mortality (OR, 4.90, 95% CI 1.68-14.28, P = 0.004; OR, 5.64, 95% CI 1.95-16.30, P = 0.001, respectively), and acute liver injury (OR, 4.50, 95% CI 2.57-7.85, P < 0.001). Methylprednisolone dose per day and cumulative dose in non-survivors were significantly higher than in survivors. CONCLUSIONS: In patients with severe COVID-19/HBV co-infection, corticosteroid treatment may be associated with increased risk of 28-day and in-hospital mortality.

Creating Awareness of Deadly Cytokine Storm to Common People and A Self Case Study

This review with case study covers the severity and hidden symptoms of cytokine storm that were missed in other articles. Most of the review studies focus on cytokine storm in a random way but this paper creates awareness to common people so that the intensity of the disease spreading can be minimized and fatality can be prevented. Cytokine storm is an umbrella term encompassing several disorders of immune disregulation. The symptoms, properties, mechanism and treatment methods for cytokine storm have been discussed along with preventive methods. Details about silent hypoxemia and its effects were also highlighted which are a major reason for not detecting this disease at early stages. This paper also describes a case of life-threatening cytokine storm caused by COVID-19 infection that was treated with clonal antibody and suppressed the cytokine release. This paper also highlights the importance of Vitamin D level in a body, which can suppress cytokines production by simultaneously boosting the innate immune system. Lesson learnt from this disease are elderly patients, especially males, with comorbidities, demonstrate increased susceptibility to poor prognosis or increased risk of severe condition or even fatality from COVID-19. Reports indicate that men appear to suffer more severe cases and die of the disease at greater rates than women, with deaths possibly up to 20 percent higher. This issue leads to future research and can work on the methods to increase the immunity of men to reach at least the immunity level of women so that fatality rate can be minimized. It has been concluded that if covid is left untreated, the cytokine starts releasing from the body and progress to extensive tissue damage, organ failure, and death.

Effect of Dexamethasone in Hospitalized Covid-19 Patients-Preliminary Report

Introduction: Covid19 is a viral disease caused due to Severe Acute Respiratory Syndrome Coronavirus 2. It causes mild to moderate lung damage.. Most of the patients are either presenting with no symptoms or with mild symptoms but there are some patients who presented with severe lung damage and needed hospitalization. Severe covid 19 is marked by inflammatory organ injury. The use of Corticosteroids helped in suppressing inflammation and reduced chances of landing in respiratory failure. Method: The trial referred to as RECOVERY (Randomized Evaluation of COVID-19 Therapy) which is controlled, randomized, open trial was performed in which 6mg dexamethasone was randomly given once daily to the patients for ten days and was then compared to the patients given basic care only. The 28-day mortality was reduced as a result. Result: 4321 patients were randomly selected for usual care treatment whereas 2104 patients were treated with dexamethasone. As a result, about 1065 (24.6%) patients on usual care and 454 patients with dexamethasone died within 28days. The reduction in mortality rate varied based on the respiratory support level at randomization. It was observed that in patients receiving dexamethasone along with invasive mechanical support;mortality rate reduced by one-third whereas it was reduced by 1/5th in patients given oxygen with mask and no decline was noticed in patients without any mechanical ventilation at randomization. Conclusion: Dexamethasone was found to reduce 28-day mortality in patients hospitalized with covid-19 who were getting either invasive mechanical ventilation or oxygen alone at the time of randomization but not in those who were not receiving any respiratory support.

E-cigarette or Vaping Product Associated Lung Injury (EVALI) Presenting As Cardiac Arrest.

E-cigarettes or vaping products became available in the market in 2004. Since then, their use has rapidly increased in all sections of society. They have been increasingly used as a "safer" alternative for combustible cigarettes and as an aid toward smoking cessation. Over time, the acceptability of e-cigarettes in public spaces increased. Lack of regulatory control also led to a rapid rise in the rate of e-cigarette/vaping product users. We report a case of a 35-year-old female who recently switched from conventional cigarettes to e-cigarette usage, and who presented to the emergency department after an out-of-hospital cardiac arrest. She was found to have bilateral extensive nodular ground-glass opacities on a CT angiogram of the chest. She needed non-invasive ventilation and was initially started on broad-spectrum antibiotic treatment for possible pneumonia. Due to a worsening clinical status, e-cigarette or vaping product associated lung injury (EVALI) diagnosis was considered, and she was started on parenteral steroid therapy, leading to rapid recovery in respiratory status. With a tapering course of steroid therapy and cessation of e-cigarette use, there was complete clinical and radiological recovery. This case highlights that EVALI can have varied clinical presentations, and the diagnosis should be considered in anyone who presents with an acute cardio-pulmonary decline and a concomitant history of e-cigarette use.

Bilateral and Multiple Central Serous Chorioretinopathy Following COVID-19 Infection: A Case Report and Literature Review.

Central serous chorioretinopathy (CSCR) following coronavirus disease 2019 (COVID-19) infection is rare. We describe an adult patient who survived a COVID-19 infection and received intravenous and oral corticosteroid treatment for three weeks. He presented three weeks post COVID-19 infection with central visual loss in both eyes for six days. Fundus examination showed multiple localized serous retinal detachments in both eyes. Optical coherence tomography (OCT) of the macula confirmed the presence of multiple areas of serous retinal detachment and pigment epithelial detachment. The patient was treated with topical non-steroidal anti-inflammatory eye drops and regained full visual recovery after three months. Corticosteroid treatment for COVID-19 and psychological stress induced by the disease are potential risk factors for the development of CSCR. Physicians should be aware of this side effect, as an early referral to an ophthalmologist for treatment is essential.

Current drugs with potential for coronavirus disease 2019 therapy: a literature review

Coronavirus disease 2019 (COVID-19) was declared as a pandemic by the WHO on 2020 a novel disease with no confirmed and precise therapeutic agent. Lopinavir/ ritonavir has shown no benefit in 199 COVID-19 hospitalized adult patients compared with standard care alone. Remdesivir has shown promising results in the first case of COVID-19 in the USA, but recent reports were disappointing and still are under more investigation in clinical trials. The arbidol (Umifenovir) and Favipiravir act well in postexposure prophylaxis and viral clearance. Interferons in combination with other antiviral agents, if administered in the early stages of the disease, can cause advantageous effects. Ribavirin is no more recommended in new guidelines. Tocilizumab (Actemra) is an effective treatment in severe patients of COVID-19 and a new therapeutic strategy. Systemic corticosteroids seem to have a great impact in reducing mortality rate in mechanically ventilated patients. There are also some supplementary agents such as vitamin C, A, D, selenium, and zinc that have been reported to be effective in the prevention and treatment of viral infections. Recent findings indicate human recombinant soluble angiotensin-converting enzyme 2, niclosamide, and ivermectin had strong in-vitro results which can lead to fast in-vivo trials and help us to control infection.

COVID-19-Associated Eosinopenia in a Patient With Chronic Eosinophilia Due to Chronic Strongyloidiasis.

Eosinopenia was frequently encountered in patients with coronavirus disease 2019 (COVID-19). We describe a case of a 59-year-old man who was treated with high-dose corticosteroids and anti-interleukin 1 receptor antagonist therapy because of severe acute respiratory distress syndrome due to a so-called cytokine storm in COVID-19. He had chronic eosinophilia for many years due to an unknown Strongyloides stercoralis infection, proven by serology and a positive polymerase chain reaction test on a stool sample. COVID-19 led to a complete resolution of eosinophilia, even before immunosuppressive treatment was started. Eosinophilia returned after recovery from COVID-19 and started to decline under treatment with ivermectin. Our case confirms previous reports of eosinopenia in COVID-19, as it appears even in patients with chronic eosinophilia. Presence of eosinophilia should prompt screening for strongyloidiasis in all patients eligible for immunosuppressive therapy because of the risk of Strongyloides hyperinfection syndrome, especially if this treatment is empirical.

Risk Factors for Fungal Co-Infections in Critically Ill COVID-19 Patients, with a Focus on Immunosuppressants.

Severe cases of coronavirus disease 2019 (COVID-19) managed in the intensive care unit are prone to complications, including secondary infections with opportunistic fungal pathogens. Systemic fungal co-infections in hospitalized COVID-19 patients may exacerbate COVID-19 disease severity, hamper treatment effectiveness and increase mortality. Here, we reiterate the role of fungal co-infections in exacerbating COVID-19 disease severity as well as highlight emerging trends related to fungal disease burden in COVID-19 patients. Furthermore, we provide perspectives on the risk factors for fungal co-infections in hospitalized COVID-19 patients and highlight the potential role of prolonged immunomodulatory treatments in driving fungal co-infections, including COVID-19-associated pulmonary aspergillosis (CAPA), COVID-19-associated candidiasis (CAC) and mucormycosis. We reiterate the need for early diagnosis of suspected COVID-19-associated systemic mycoses in the hospital setting.

Impact of Systemic Corticosteroids on Mortality in Older Adults With Critical COVID-19 Pneumonia.

BACKGROUND: The most susceptible population group to critical and fatal coronavirus disease 2019 (COVID-19) is older adults. In severe acute respiratory syndrome coronavirus 2 infection, the host immune response is thought to play a key role in the pathophysiological effects of lung damage. Therefore, corticosteroid therapy could modulate inflammation-mediated pulmonary injury and thereby reduce progression to severe respiratory failure and death. The aim of this study was to analyze the safety and clinical efficacy of corticosteroid therapy in older adults with severe COVID-19 pneumonia. METHOD: We reviewed the clinical records of confirmed COVID-19 patients aged 75 years or older admitted to our hospital over a 3-month period (March 1-May 31, 2020). A total of 143 patients were included in the study cohort. From 2 April, 2020, in accordance with World Health Organization guidance on COVID-19, our hospital protocol added corticosteroid for COVID-19 treatment. We compared in-hospital mortality among patients with critical COVID-19 who received corticosteroids therapy and those who did not. RESULTS: In total, 88 patients (61.5%) were treated with corticosteroids, and 55 patients (38.4%) were not. Both groups were similar in baseline characteristics. The median age was 85 years (interquartile range: 82-89), and 61.5% (88/143) were male. In-hospital mortality was lower in the corticosteroid group (68.2%) compared with patients in the noncorticosteroid group (81.8%). Treatment with corticosteroids was an independent survival factor (hazard ratio: 0.61; 95% CI: 0.41-0.93; p = .006). CONCLUSIONS: In critically ill older adults with COVID-19 pneumonia, the use of corticosteroid treatment resulted in lower mortality without severe adverse events.

The effect of corticosteroid treatment on patients with coronavirus infection: a systematic review and meta-analysis.

OBJECTIVES: An outbreak of novel coronavirus in 2019 threatens the health of people, and there is no proven pharmacological treatment. Although corticosteroids were widely used during outbreaks of severe acute respiratory syndrome and Middle East respiratory syndrome, their efficacy remainedhighly controversial. We aimed to further evaluate the influence of corticosteroids on patients with coronavirus infection. METHODS: We conducted a comprehensive search of literature published in PubMed, Embase, Cochrane library, and China National Knowledge Infrastructure (CNKI) from January 1, 2002 to March 15, 2020. All statistical analyses in this study were performed on stata14.0. RESULTS: A total of 5270 patients from 15 studies were included in this meta-analysis. The result indicated that critical patients were more likely to require corticosteroids therapy (risk ratio [RR] = 1.56, 95% confidence interval [CI] = 1.28-1.90, P<0.001). However, corticosteroid treatment was associated with higher mortality (RR = 2.11, 95%CI = 1.13-3.94, P = 0.019), longer length of stay (weighted mean difference [WMD] = 6.31, 95%CI = 5.26-7.37, P<0.001), a higher rate of bacterial infection (RR = 2.08, 95%CI = 1.54-2.81, P<0.001), and hypokalemia (RR = 2.21, 95%CI = 1.07-4.55, P = 0.032) but not hyperglycemia (RR = 1.37, 95%CI=0.68-2.76, P = 0.376) or hypocalcemia (RR = 1.35, 95%CI = 0.77-2.37, P = 0.302). CONCLUSIONS: Patients with severe conditions are more likely to require corticosteroids. Corticosteroid use is associated with increased mortality in patients with coronavirus pneumonia.
