Liver injury in patients with COVID-19 who received dexamethasone monotherapy

Introduction: Liver injury is frequently seen in coronavirus disease 2019 (COVID-19), and it has been reported to be associated with the severity of COVID-19. The direct action of the virus, cytokine storm, coagulation abnormalities, drug-induced, etc. are considered to be the causes of liver injury, and antiviral agents against COVID-19 and steroids used as anti-inflammatory agents have also been reported to contribute to the appearance of liver injury. In Japan, remdesivir, dexamethasone (Dex), baricitinib, etc. are used as therapeutic agents for COVID-19, but there is still not enough evidence about the frequency of liver injury as an adverse event. Aims & Methods: This study aimed to clarify the influence of Dex monotherapy for liver injury in COVID-19 with respiratory failure. We examined 171 patients with COVID-19 with liver injury in the respiratory failure groups and the nonrespiratory failure groups and investigated 41 patients with moderate COVID-19 with respiratory failure who received Dex monotherapy in the liver injury group and the nonliver injury group at the time before treatment. Result(s): The respiratory failure group had 64% more liver damage than the non-respiratory failure group, was older, had more men, and had significantly more complications of lifestyle-related diseases such as hypertension and diabetes. Obesity was more common in the liver injury group prior to Dex monotherapy, and the liver CT value was significantly lower than in the non-liver injury group. Liver injury worsened in 41% of patients after Dex monotherapy, but there was no significant difference in the frequency before Dex monotherapy between the liver injury group and the non-liver injury group, and the degree of liver injury was mild in all cases, improving in 38% of the liver injury group. Conclusion(s): Dex monotherapy was a safe treatment for moderate COVID-19 with respiratory failure, which frequently resulted in liver injury.

Updates in Nephrology for the Hospitalist

This chapter gives a broad overview of nephrology as it affects hospitalists while also hoping to answer a few of the essential questions hospitalists may ask their nephrology colleagues. Evaluation and treatment of both acute and chronic kidney disease is constantly evolving as the small but tight-knit community of hospital-nephrologists continue to collect, review, and research data. The majority of the chapter will be focused on discussing a few new updates in the field of nephrology and how these updates could potentially change hospital care. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Clinical Approaches to the COVID-19 Pandemic

SARS-CoV-2 is a highly contagious virus that can affect almost any system in the body. New developments in understanding its transmissibility, management, and sequelae are unfolding almost daily. However, no medical publication in 2021 would be complete without a snapshot of the current status of this pandemic. The virus continues to mutate to more contagious, and therefore more dangerous, strains. The best path forward through this pandemic is vaccination against SARS-CoV-2 for all those who are eligible. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Methylprednisolone Versus Dexamethasone for Treatment of Severe or Critical Covid-19: A Quasi-Experimental Study (Md Treat)

Intro: Dexamethasone, a corticosteroid, was recently demonstrated to be the only medication capable of reducing mortality in severe COVID disease in the UK's Recovery Trial. There is a need to compare different steroids because it is well recognised that different corticosteroids have varied pharmacodynamic properties. The aim of our study was to compare outcomes in severe or critical COVID-19 when treated with Dexamethasone versus Methyl prednisolone. Method(s): We conducted a retrospective quasi-experimental, non-randomized study to determine whether intravenous or oral dexamethasone reduces mortality compared with intravenous methylprednisolone in patients with severe or critical COVID-19.The study was conducted on all patients aged 18 and over admitted at a 700-bedded academic medical center.The primary outcome was the mortality. The secondary outcome included length of stay. Finding(s): A total of 706 hospitalized patients with moderate to severe COVID- 19 were included in the study. There were n=217 patients in Dexamethasone group, n= 393 patients in Methylprednisolone group and n=96 patients who did not receive steroids.Among the baseline characteristics between the groups, there was no significant difference in median age (55 years in dexamethsone group vs 57 years in methyl prednisolone group p=0.09). There was male predominance in methylprednisolone group (74% versus 54% p<0.001) and a greater proportion of patients who required invasive mechanical ventilation (13.7% versus 3.2% p<0.001). Mortality was found to be significantly higher in methylprednisolone group compared to dexamethasone group on univariate logistic regression analysis (13.7% versus 3.2% p<0.001) and longer length of stay (7 days versus 4 days p<0.001). In multivariable model, dexamethsone was found to be associated with lower risk of mortality (aOR: 0.24;95% CI: (0.09- 0.62)(p=0.003) and lesser length of stay (aOR: 0.87;95% CI: (0.82-0.92) (p<0.001). Conclusion(s): Dexamethasone was associated with lower mortality and lesser length of stay when compared to Methyl prednisolone in moderate to critical COVID-19.Copyright © 2023

High mortality among patients with severe COVID-19 and Do Not Intubate orders

INTRODUCTION. Moderate to severe respiratory distress among patients with COVID-19 is associated with a high mortality. This study evaluated ventilator support and mortality by Do Intubate (DI) or Do Not Intubate (DNI) orders. METHODS. This was a retrospective study of patients with COVID-19 and a supplemental oxygen requirement of 15 l/min. The patients were divided into two groups corresponding to the first and second wave of COVID-19 and were subsequently further divided according to DI and DNI orders and analysed regarding need of ventilator support and mortality. RESULTS. The study included 178 patients. The mortality was 24% for patients with DI orders (n = 115) and 81% for patients with DNI orders (n = 63) increasing to 98% (n = 46) for patients with DNI orders and very high flow oxygen requirements ( 30 l/min.). From the first to the second wave of COVID-19, the use of constant continuous positive airway pressure (cCPAP) increased from 71% to 91% (p < 0.001), whereas the use of mechanical ventilation decreased from 54% to 28% (odds ratio = 0.38 (95% confidence interval: 0.17-0.85)). CONCLUSION. The mortality was high for patients with DNI orders and respiratory distress with very high levels in supplemental oxygen in both the first and second wave of COVID-19 despite an increase in use of cCPAP and treatment with dexamethasone and remdesivir during the second wave. Hence, careful evaluation on transition to palliative care must be considered for these patients.

Viral Myopericarditis and Viral Encephalitis as Manifestations of Covid-19 Infection: A Case Report

Intro: Coronavirus disease (COVID-19) is currently a global health crisis and is caused by a new strain of coronavirus. However, emerging literature of case reports noted possible extrapulmonary manifestations of the disease. Because COVID 19 is a relatively new disease, at present, little existing literature tackles the diagnosis and therapeutic management of COVID-19-related conditions outside the pulmonary system. Method(s): This is a case of a 24-year-old male presented with the chief complaint of sudden stiffening of all extremities. Non-contrast computed tomography (CT) scan was unremarkable. Chest X-ray revealed interstitial pneumonia and SARS-CoV-2 RT-PCR (OPS/NPS) was positive. Electrocardiogram (ECG) findings showed supraventricular tachycardia and had elevated Troponin I levels. Pertinent physical findings noted were slurring of speech, dysmetria, and vertical nystagmus. Finding(s): The patient was initially treated as a case of Bacterial Abscess versus Viral encephalitis. Pericardial ultrasound revealed small pericardial effusion and was started on Colchicine. Repeat cranial CT scan noted unremarkable results but due to persistence of symptoms, the patient was started with Dexamethasone. On Day 16 of illness, the patient was noted to have full resolution of symptoms. Rapid antibody testing was done which revealed positive for both IgG and IgM hence the patient was discharged with the final diagnosis of Viral Myopericarditis resolved, Viral encephalitis resolved, COVID-19 pneumonia recovered. Conclusion(s): Extrapulmonary manifestations have been reported increasingly as an atypical presentation of COVID 19 infection. Early recognition of viral myopericarditis and viral encephalitis as a manifestation of COVID 19 can lead to the initiation of proper treatment and management. More reports on these cases can aid future studies on diagnostics and therapeutic approaches during the COVID-19 pandemic.Copyright © 2023

Acute Kidney Injury in Critical Care COVID-19 Patients on Invasive Mechanical Ventilation: The Potential Preventive Role of Dexamethasone.

Background: A high incidence of acute kidney injury (AKI) has been reported in coronavirus disease 2019 (COVID-19) patients in critical care units and those undergoing invasive mechanical ventilation (IMV). The introduction of dexamethasone (DXM) as treatment for severe COVID-19 has improved mortality, but its effects in other organs remain under study. Objective: The objective of this study was to evaluate the association between DXM and AKI in COVID-19. Methods: In this prospective observational cohort study, we evaluated the incidence of AKI in critically ill COVID-19 patients undergoing mechanical ventilation, and the association of DXM treatment with the incidence, severity, and outcomes of AKI. The association between DXM treatment and AKI was evaluated by multivariable logistic regression. The association of the combination of DXM treatment and AKI on mortality was evaluated by Cox-regression analysis. Results: We included 552 patients. AKI was diagnosed in 311 (56%), of which 196 (63%) corresponded to severe (stage 2 or 3) AKI, and 46 (14.8%) received kidney replacement therapy. Two hundred and sixty-seven (48%) patients were treated with DXM. This treatment was associated to lower incidence of AKI (Odds Radio 0.34, 95% Confidence intervals [CI] 0.22-0.52, p < 0.001) after adjusting for age, body mass index, laboratory parameters, SOFA score, and vasopressor use. DXM treatment significantly reduced mortality in patients with severe AKI (HR 0.63, 95%CI 0.41-0.96, p = 0.032). Conclusions: The incidence of AKI is high in COVID-19 patients under IMV. DXM treatment is associated with a lower incidence of AKI and a lower mortality in the group with severe AKI.

Management of autoimmune retinopathy treated with intravitreal dexamethasone implant.

PURPOSE: The purpose of this study is to evaluate clinical outcomes of autoimmune retinopathy (AIR) in the patients treated with intravitreal dexamethasone implant (IDI). METHOD: Twenty-one eyes of 11 AIR patients treated with at least 1 injection of IDI were retrospectively reviewed. Clinical outcomes before and after treatment, including best corrected visual acuity (BCVA), optic coherence tomography (OCT), fundus autofluorescence (FAF), full-field electroretinography (ff-ERG), and visual field (VF) at last visit within 6 and/or 12 months, were recorded. RESULTS: Among all the patients, 3 had cancer-associated retinopathy (CAR) and 8 had non-paraneoplastic-AIR (npAIR) with mean followed up of 8.52 ± 3.03 months (range 4-12 months). All patients achieved improved or stable BCVA within 6 and/or 12 months after the treatment. Cystoid macular edema (CME) in 2 eyes and significant retinal inflammation in 4 eyes were markedly resolved after single injection. Central retinal thickness (CFT) in all eyes without CME, ellipsoid zone (EZ) on OCT in 71.4% of eyes, ERG response in 55% of eyes, and VF in 50% of eyes were stable or improved within 6 months after treatment. At last visit within 12 months, both BCVA and CFT remained stable in the eyes treated with either single or repeated IDI; however, progression of EZ loss and damage of ERG response occurred in some patients with single IDI. CONCLUSION: Clinical outcomes, including BCVA and parameters of OCT, ERG, and VF, were stable or improved after IDI in a majority of AIR patients. Local treatment of AIR with IDI was a good option to initiate the management or an alternative for the patients' refractory to the systemic therapy but with limited side effect.
