Development of giant cell arteritis after vaccination against SARS-CoV2: A case report and literature review.

RATIONALE: Giant cell arteritis (GCA) is an autoimmune vasculitis that affects large and medium-sized blood vessels. The mRNA vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) has been associated with the development of immune-mediated diseases. In this article, we present a case of GCA that developed after vaccination against SARS-CoV2. PATIENT CONCERNS: A 77-year-old man developed fever, general fatigue, and headache 1 day after the third dose of vaccination against SARS-CoV2. Nodular swelling and tenderness of the bilateral temporal arteries were observed. DIAGNOSES: Although right temporal artery biopsies were negative, the patient was diagnosed with GCA based on criteria established by the American College of Rheumatology for the classification of GCA. INTERVENTIONS: The patient received methylprednisolone 1000 mg for 3 days. This was followed by prednisolone 1 mg/kg/d, which was decreased by 10 mg every week to 30 mg. From day 16 of hospitalization, the patient received tocilizumab 162 mg/wk every other week. OUTCOMES: There was no occurrence of acute side effects. After 38 days of treatment, the condition improved and the patient was discharged from the hospital; as stated above, the dose of prednisolone was tapered to 30 mg/d. LESSONS: We experienced a case of GCA that occurred immediately after vaccination against SARS-CoV2 with an mRNA vaccine. Early signs of GCA include fever, fatigue, and headache, and often resemble those noted after vaccination against SARS-CoV2. The potential presence of GCA should be determined in individuals with persistent fever and headache after vaccination against SARS-CoV2.

A systematic review and meta-analysis of glucocorticoids treatment in severe COVID-19: methylprednisolone versus dexamethasone.

OBJECTIVE: The preferred agent of glucocorticoids in the treatment of patients with severe COVID-19 is still controversial. This study aimed to compare the efficacy and safety of methylprednisolone and dexamethasone in the treatment of patients with severe COVID-19. METHODS: By searching the electronic literature database including PubMed, Cochrane Central Register of Controlled Trials, and Web of Science, the clinical studies comparing methylprednisolone and dexamethasone in the treatment of severe COVID-19 were selected according to the inclusion criteria and exclusion criteria. Relevant data were extracted and literature quality was assessed. The primary outcome was short-term mortality. The secondary outcomes were the rates of ICU admission and mechanical ventilation, PaO2/FiO2 ratio, plasma levels of C-reactive protein (CRP), ferritin, and neutrophil/lymphocyte ratio, hospital stay, and the incidence of severe adverse events. Statistical pooling applied the fixed or random effects model and reported as risk ratio (RR) or mean difference (MD) with the corresponding 95% confidence interval (CI). Meta-analysis was performed using Review Manager 5.1.0. RESULTS: Twelve clinical studies were eligible, including three randomized controlled trials (RCTs) and nine non-RCTs. A total of 2506 patients with COVID-19 were analyzed, of which 1242 (49.6%) received methylprednisolone and 1264 (50.4%) received dexamethasone treatment. In general, the heterogeneity across studies was significant, and the equivalent doses of methylprednisolone were higher than that of dexamethasone. Our meta-analysis showed that methylprednisolone treatment in severe COVID-19 patients was related to significantly reduced plasma ferritin and neutrophil/lymphocyte ratio compared with dexamethasone, and that no significant difference in other clinical outcomes between the two groups was found. However, subgroup analyses of RCTs demonstrated that methylprednisolone treatment was associated with reduced short-term mortality, and decreased CRP level compared with dexamethasone. Moreover, subgroup analyses observed that severe COVID-19 patients treated with a moderate dose (2 mg/kg/day) of methylprednisolone were related to a better prognosis than those treated with dexamethasone. CONCLUSIONS: This study showed that compared with dexamethasone, methylprednisolone could reduce the systemic inflammatory response in severe COVID-19, and its effect was equivalent to that of dexamethasone on other clinical outcomes. It should be noted that the equivalent dose of methylprednisolone used was higher. Based on the evidence of subgroup analyses of RCTs, methylprednisolone, preferably at a moderate dose, has an advantage over dexamethasone in the treatment of patients with severe COVID-19.

Successive onset of Vogt-Koyanagi-Harada syndrome in father and son.

BACKGROUND: Vogt‒Koyanagi‒Harada (VKH) disease is a multifactorial systemic autoimmune disorder against melanocytes that is characterized by panuveitis. Familial occurrence of VKH disease is rare. Here, we report two cases of a father and his son with characteristic manifestations of VKH disease. CASE PRESENTATION: A 53-year-old male with typical clinical symptoms of VKH disease was referred to Tangshan Eye Hospital. Examination showed the presence of ciliochoroidal effusion and exudative retinal detachment in both eyes. The patient was given intravenous methylprednisolone 120 mg for 2 days and intravenous methylprednisolone 80 mg for 1 day followed by 48 mg (1 mg/kg/day) oral methylprednisolone daily, accompanied by oral azathioprine 50 mg daily. Cycloplegic agent (0.5% tropicamide three times daily [TID]) was added. The patient was free of symptoms and recurrence within more than 1-year-follow-up period, the best corrected visual acuity (BVCA) was increased and maintained in both eyes with complete resolution of subretinal fluid. One year and nine months later, case 2 (his son) also presented with the typical clinical symptoms of VKH disease at 29 years of age. The son also recovered from VKH disease after routine and standard treatment. CONCLUSIONS: To the best of our knowledge, this is the first VKH disease case report of a father-son relationship. Although genetic factors have been demonstrated to be involved in the pathogenesis of VKH disease, the different inheritance modes of VKH patients need to be further explored and studied.

Evaluation of steroid therapy in COVID-19 patients; in the right dose at the right time to the right patients.

Background: Although there is still no universally accepted treatment agent, steroids have been administered chronologically at every dose and at every stage of the COVID-19 pandemic. Aim: We aimed to evaluate the clinical efficacy of high-dose steroid therapy and its effect on mortality in COVID-19 patients with severe pneumonia, severe Acute Respiratory Distress Syndrome (ARDS), and septic shock. Patients and Methods: : Patients with severe pneumonia, septic shock, and ARDS due to COVID-19 who were followed up in the intensive care unit were retrospectively reviewed. Results: The study population was divided into two groups; the methylprednisolone pulse group (MP) (n = 55) and the dexamethasone group (Dex) (n = 39). When the values before and after treatment were compared; there was a statistically significant increase in the neutrophil/lymphocyte ratio after treatment in the MP group (p = 0.006). Although it was not statistically significant in the MP group, There was a numerical increase in D-dimer levels (p = 0.28). Thromboembolic complications developed in 2 patients in the MP group. The mortality outcomes of the groups were statistically similar (p = 0.943). Conclusion: We recommend steroids use in the condition that it is indicated in the critically ill group with the poor general condition. Since there is no significant difference between high-dose pulse steroid treatment and standard treatment doses, we think that the risk of complications should not be taken into account and high doses should not be used.

Transverse Myelitis as a Rare Neurological Complication of Coronavirus Disease 2019: A Case Report and Literature Review.

The novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is primarily a respiratory virus. However, an increasing number of neurologic complications associated with this virus have been reported, e.g., transverse myelitis (TM). We report a case of a 39-year-old man admitted to Namazi Hospital affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In December 2020, the patient was infected with Coronavirus Disease 2019 (COVID-19). During hospitalization, the patient suffered from sudden onset of paraplegia, and urinary retention, and had a T6-T7 sensory level. TM was diagnosed and an extensive workup was performed to rule out other etiologies. Eventually, para-infectious TM associated with COVID-19 was concluded. The patient received pulse methylprednisolone therapy of 1 g/day for 10 consecutive days followed by seven sessions of plasma exchange without a favorable response. The patient then underwent regular physical rehabilitation and tapering oral administration of prednisolone 1 mg/Kg. As a result, weakness in the lower extremities improved slightly after six months. Overall, we suspect a correlation between COVID-19 and TM, however, further studies are required to substantiate the association.

Anti-myelin Oligodendrocyte Glycoprotein Antibody-positive Myelitis after Coronavirus Disease 2019.

We herein report a case of anti-myelin oligodendrocyte glycoprotein (MOG) antibody-related myelitis caused by coronavirus disease (COVID-19) infection in 2021. A 22-year-old man with no history of any related illness contracted COVID-19. Eight days later, he developed bladder problems, paraplegia and sensory disturbances. Cervical spinal cord magnetic resonance imaging revealed extensive hyperintensity at T2 and spinal cord lesions extending from C4 to Th1. The patient was diagnosed with transverse myelitis and started on intravenous methylprednisolone, plasma exchange and intravenous immunoglobulin therapy. The symptoms improved only after intravenous methylprednisolone therapy. Anti-MOG antibodies were found in his serum and cerebrospinal fluid during routine screening. As this observation is unusual and could cause serious health problems, we wonder if COVID-19 triggered this autoimmune response.

Granulomatosis with Polyangiitis following COVID-19 in an Adolescent.

Granulomatosis with polyangiitis (GPA) is a systemic disease that causes vasculitis in various organs. Although the mechanism of pathogenesis remains unclear, infection has been reported to be a causative factor. We herein report a case of GPA that developed following coronavirus disease 2019 (COVID-19) in an adolescent girl. One month after contracting mild COVID-19, the patient had facial allodynia, a fever, and weight loss and was admitted for multiple nodular shadows on a chest roentgenogram. GPA was diagnosed based on pathological findings of the lung and nasal mucosal biopsies. She received methylprednisolone and rituximab, and her symptoms and radiological findings improved.

Ruxolitinib and methylprednisolone for treatment of patients with relapsed/refractory multiple myeloma.

Although Janus kinase (JAK) inhibitors have demonstrated efficacy for treating autoimmune disorders and myeloproliferative neoplasms, their efficacy in treating other types of cancer has not been clearly demonstrated. We evaluated oral ruxolitinib (15 mg twice daily) with oral methylprednisolone (40 mg every other day) for multiple myeloma (MM) patients with progressive disease who had received a proteasome inhibitor, lenalidomide, glucocorticosteroids and three or more prior regimens. All of the planned 29 patients had been enrolled with follow-up until 28 April 2022. Median lines of prior therapy were 6 (range 3-12). Cytogenetics and fluorescent in situ hybridization were evaluable in 28 patients; 9 (32%) and 17 (70%) patients showed high-risk cytogenetics and/or 1q+, respectively. The overall response rate was 31%. The median duration of response was 13.1 (range 2.8-22.0) months. Median progression-free survival rate was 3.4 (range 0.5-24.6) months, Overall, the treatment was well tolerated. The combination of ruxolitinib and methylprednisolone demonstrated significant clinical activity among previously heavily-treated MM patients, and responses were achieved among patients who had high-risk cytogenetics. This is the first clinical study to show activity of JAK inhibitors in combination with steroids for MM patients and expands the potential use of these drugs to those with cancers other than myeloproliferative neoplasms.

Lumbosacral Radiculoplexus Neuropathy After COVID-19.

INTRODUCTION: Lumbosacral Radiculoplexus Neuropathy (LRPN) is a subacute, painful, paralytic, asymmetric immune-mediated lower-limb neuropathy associated with weight loss and diabetes mellitus (called DLRPN). Approximately one-third of LRPN cases have a trigger. Our purpose is to show that COVID-19 can trigger LRPN. CASE REPORT: We describe the clinical, neurophysiological, radiologic, and pathologic findings of a 55-year-old man who developed DLRPN after severe acute respiratory syndrome coronavirus-2 infection. Shortly after mild coronavirus disease 2019 (COVID-19), the patient developed severe neuropathic pain (allodynia), postural orthostasis, fatigue, weight loss, and weakness of bilateral lower extremities requiring wheelchair assistance. One month after COVID-19, he was diagnosed with type 2 diabetes mellitus. Neurological examination showed bilateral severe proximal and distal lower extremity weakness, absent tendon reflexes, and pan-modality sensation loss. Electrophysiology demonstrated an asymmetric axonal lumbosacral and thoracic radiculoplexus neuropathies. Magnetic resonance imaging showed enlargement and T2 hyperintensity of the lumbosacral plexus. Cerebral spinal fluid (CSF) showed an elevated protein (138 mg/dL). Right sural nerve biopsy was diagnostic of nerve microvasculitis. He was diagnosed with DLRPN and treated with intravenous methylprednisolone 1 g weekly for 12 weeks. The patient had marked improvement in pain, weakness, and lightheadedness and at the 3-month follow-up was walking unassisted. CONCLUSION: COVID-19 can trigger postinfectious inflammatory neuropathies including LRPN.

Methylprednisolone versus intravenous immunoglobulins in children with paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS): an open-label, multicentre, randomised trial.

BACKGROUND: The emergence of paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) led to the widespread use of anti-inflammatory treatments in the absence of evidence from randomised controlled trials (RCTs). We aimed to assess the effectiveness of intravenous methylprednisolone compared with intravenous immunoglobulins. METHODS: This is an open-label, multicentre, two-arm RCT done at ten hospitals in Switzerland in children younger than 18 years hospitalised with PIMS-TS (defined as age <18 years; fever and biochemical evidence of inflammation, and single or multiorgan dysfunction; microbiologically proven or putative contact with SARS-CoV-2; and exclusion of any other probable disease). Patients were randomly assigned 1:1 to intravenous methylprednisolone (10 mg/kg per day for 3 days) or intravenous immunoglobulins (2 g/kg as a single dose). The primary outcome was length of hospital stay censored at day 28, death, or discharge. Secondary outcomes included proportion and duration of organ support. Analyses were done by intention-to-treat. The study was registered with Swiss National Clinical Trials Portal (SNCTP000004720) and ClinicalTrials.gov (NCT04826588). FINDINGS: Between May 21, 2021, and April 15, 2022, 75 patients with a median age of 9·1 years (IQR 6·2-12·2) were included in the intention-to-treat population (37 in the methylprednisolone group and 38 in the intravenous immunoglobulins group). The median length of hospital stay was 6·0 days (IQR 4·0-8·0) in the methylprednisolone group and 6·0 days (IQR 5·0-8·8) in the intravenous immunoglobulins group (estimated effect size -0·037 of the log10 transformed times, 95% CI -0·13 to 0·065, p=0·42). Fewer patients in the methylprednisolone group (ten [27%] of 37) required respiratory support compared with the intravenous immunoglobulin group (21 [55%] of 38, p=0·025). Need and duration of inotropes, admission to intensive care units, cardiac events after baseline, and major bleeding and thrombotic events were not significantly different between the study groups. INTERPRETATION: In this RCT, treatment with methylprednisolone in children with PIMS-TS did not significantly affect the length of hospital stay compared with intravenous immunoglobulins. Intravenous methylprednisolone could be an acceptable first-line treatment in children with PIMS-TS. FUNDING: NOMIS Foundation, Vontobel Foundation, and Gaydoul Foundation.

A case of antisynthetase syndrome presenting solely with life-threatening interstitial lung disease.

A previously fit and well 38-year-old man presented during the COVID-19 pandemic with dyspnoea, cough and palpitations. C-reactive protein was elevated and chest X-ray demonstrated bilateral lower zone consolidation. SARS CoV-2 swab was negative. He was diagnosed with community-acquired pneumonia and treated with oral antibiotics. He developed severe type 1 respiratory failure and was admitted to the high-dependency unit for non-invasive ventilation. CTPA was negative for pulmonary embolism, instead demonstrating bilateral organising pneumonia. Empirical treatment for swab-negative COVID-19 pneumonitis was started; however, further deterioration ensued and prompted intubation and ventilation. Microbiological testing did not yield any positive results, thereby raising suspicion for the presence of an autoimmune disease. Pulsed intravenous methylprednisolone was administered with good effect. ENA screen was positive for anti-Jo1 and myositis-specific autoantibodies were positive for Ro-52, Ku and PL-12. The patient was extubated and did not exhibit any muscle weakness on clinical examination. Creatine kinase was only mildly elevated. He was diagnosed with amyopathic antisynthetase syndrome - frequently considered as a form of idiopathic inflammatory myopathy (IIM) - and treated with further intravenous methylprednisolone and cyclophosphamide. Oxygen therapy was gradually weaned and the patient discharged on mycophenolate mofetil and a weaning course of oral steroids.

Myelin oligodendrocyte glycoprotein antibody-associated optic neuritis in a COVID-19 patient: A case report.

RATIONALE: Coronavirus disease 2019 (COVID-19) has spread worldwide. It involves multiple organs of infected individuals and encompasses diverse clinical manifestations. We report a case of acute optic neuritis (ON) associated with myelin oligodendrocyte glycoprotein (MOG) antibody possibly induced by COVID-19. PATIENT CONCERNS: A 47-year-old man presented to our clinic with left eye pain and vision loss. Magnetic resonance imaging of the orbit revealed the bilateral high intensity of the optic nerve sheaths. He tested positive for COVID-19 by polymerase chain reaction (PCR) testing on the day of admission but he had no signs of respiratory illness. Laboratory testing revealed that MOG immunoglobulin G (MOG IgG) was positive, but other antibodies including aquaporin-4 were negative. DIAGNOSIS: The patient was diagnosed with MOG antibody-positive acute ON possibly induced by COVID-19. INTERVENTIONS: Steroid pulse therapy consisting of methylprednisolone 1 g/day for a total of 3 days, followed by an oral prednisolone taper was performed. OUTCOMES: His left eye pain was immediately relieved, and his decimal vision improved from 0.03 to 0.1 on the day of discharge. Outpatient follow-up 2 weeks later revealed left a decimal vision of 1.2, and a complete resolution of the left eye pain. LESSONS: Our case indicated that COVID-19 might trigger an autoimmune response that leads to MOG antibody-associated ON, similar to other pathogens that were reported in the past. The treatment response to steroid pulse therapy was preferable following a typical course of MOG antibody-positive ON.

Fatal multisystem inflammatory syndrome in a 78-year-old adult after severe COVID-19 pneumonia during 2022 Omicron variant epidemic in Shanghai, China.

Multisystem inflammatory syndrome adult type (MIS-A) is a rare type of post-acute COVID-19 syndrome which more frequently occurred in younger population. Here we present a 78-year-old Chinese female, the oldest case reported, diagnosed with MIS-A who had severe SARS-CoV-2 infection. She was diagnosed with severe COVID-19 and experienced an unexpected sudden hemodynamic collapse in the recovery period within three weeks. Her platelet count was sharply dropped, accompanied with sustained cardiac, kidney and liver injury. She was diagnosed with MIS-A according to criteria established by Center of Disease Control and Prevention. Though her condition was improved under administrating with high dose of methylprednisolone and intravenous immunoglobulin, methylprednisolone was unable to withdraw till two weeks as her partial pressure of oxygen/fraction of inspiration oxygen ratio and platelet count dropped on the heels of decreasing dosage. Unfortunately, the patient's condition gradually deteriorated with the development of severe nosocomial pneumonia. We presented this rare case in order to emphasize that MIS-A could occur in the elderly and the management of this population might be more difficult as the condition of the elderly with SARS-CoV-2 infection and MIS-A might be more severe.

Polyarteritis nodosa presenting with posterior reversible leukoencephalopathy syndrome.

A man in his 20s presented following a generalised tonic-clonic seizure on a background of a recent diagnosis of hepatitis B (HBV). During admission, he was severely hypertensive and imaging findings confirmed a diagnosis of posterior reversible leukoencephalopathy syndrome (PRES). The patient subsequently developed multiorgan involvement with an axonal sensorimotor neuropathy, vascular cutaneous lesions and multiple bilateral renal and splenic infarcts. Based on the 2012 Revised International Chapel Hill Consensus Criteria, a diagnosis of polyarteritis nodosa (PAN) with secondary PRES was made. The patient was given intravenous methylprednisolone, followed by a prolonged course of oral prednisolone, and tenofovir antiviral therapy to target HBV seroconversion. He made a good neurological recovery with resolution of imaging changes. This case highlights the importance of a low threshold for systemic screening for young patients presenting with PRES secondary to uncontrolled hypertension and the importance of viral screening, particularly for HBV.

Early Stage Combination Treatment with Methylprednisolone Pulse and Remdesivir for Severe COVID-19 Pneumonia.

BACKGROUND: This study evaluated the clinical outcomes of patients with severe COVID-19 pneumonia treated with remdesivir plus standard corticosteroid treatment (SCT) or with remdesivir plus high-dose corticosteroid pulse therapy (HDCPT). METHODS: One hundred and two patients with severe COVID-19 pneumonia and respiratory failure were included. The patients were divided into two cohorts. The first comprised patients who received remdesivir and SCT, consisting of 6 mg dexamethasone daily for up to 10 days or until hospital discharge. The second included patients who received remdesivir and HDCPT, composed of 250 mg iv of methylprednisolone for three days, followed by a slow reduction in the dose of steroids. The severity of hypoxemia was assessed using the SaO2/FiO2 peripheral oxygen saturation index. RESULTS: 55 received remdesivir plus HDCPT, and 47 received remdesivir plus SCT. Mortality at 30 days was significantly lower among patients who received remdesivir plus HDCPT (4/55) than among those who did not (15/47). In patients who received remdesivir plus HDCPT, 7.3% required invasive mechanical ventilation and admission to the ICU and 36.4% non-invasive ventilation versus 29.8% and 61.7%, respectively, among those treated with remdesivir plus SCT. Remdesivir plus HDCPT induced a significantly faster improvement in the SaO2/FiO2 index. CONCLUSION: Early combination treatment with remdesivir plus HDCPT reduced in-hospital mortality and the need for admission to the ICU. Furthermore, it improved the SaO2/FiO2 index faster in patients with severe COVID-19 pneumonia.

Methylprednisolone in severe COVID-19 with acute respiratory distress syndrome - less is more?

INTRODUCTION: Corticosteroids, particularly methylprednisolone, are part of the treatment for severe COVID-19 with acute respiratory distress syndrome (ARDS). In this study, we aimed to compare the mortalities of patients treated with higher versus lower doses of methylprednisolone. Secondary outcomes included oxygenation, need for mechanical ventilation, length of stay in intensive care unit (ICU), secondary infection, improvement of PaO2/FiO2 (PF) ratio, and inflammatory response as expressed by C-reactive protein (CRP). MATERIALS AND METHODS: A retrospective cohort study conducted at Sarawak General Hospital from 1st June to 30th September 2021. Patients who received intravenous methylprednisolone for severe COVID-19 in the ICU were identified and divided into two groups: higher dose (cumulative dose more than 10 mg per kg) and lower dose (cumulative dose less than 10 mg per kg). RESULTS: Out of a total of 165 patients, 40 (24.2%) patients received higher dose methylprednisolone. There was no significant difference in socio-demographic characteristics (age, gender, body mass index), COVID-19 vaccination status, laboratory parameters (lymphocyte count, CRP, lactate dehydrogenase, D-dimer), or usage of immunomodulator therapy between the groups. Overall mortality was 23.6%. Mortality in the higher dose group was twice as high compared to lower dose group (37.5% versus 19.2%) (OR 3.79, 95% CI 1.24-11.59, p<0.05). In addition, the higher dose cohort developed more secondary infections (87.5%) and had longer stays in ICU (median 11 days, IQR 8- 15). No significant difference was found between both cohorts in terms of CRP reduction, improvement of PF ratio, or the need for mechanical ventilation post methylprednisolone. CONCLUSION: In this study, the use of higher dose methylprednisolone in COVID-19 with ARDS was not associated with better clinical outcomes. A lower dose of methylprednisolone might be sufficient in treating severe COVID-19 with ARDS.
