Repeated Intravenous Methylprednisolone May Prevent Deterioration of Hypertrophic Pachymeningitis in Rosai-Dorfman Disease.

Rosai-Dorfman disease (RDD) is a rare form of non-Langerhans cell histiocytosis. Although 20% of patients with RDD have spontaneous remission, some cases with central nervous system (CNS) involvement require surgery or systemic treatment. We encountered a case of RDD in which hypertrophic pachymeningitis was diffuse, eliminating the need for surgical intervention. A 72-year-old Japanese man was diagnosed with RDD based on pathological lymph node findings. Repeated intravenous methylprednisolone (IVMP) administration resolved and stabilized the hypertrophic pachymeningitis without any sequelae. If surgery or anticancer medications are contraindicated, repeated IVMP may be a good therapeutic option for CNS-associated RDD.

Effectiveness of intravenous methylprednisolone pulse in patients with severe microscopic polyangiitis and granulomatosis with polyangiitis.

OBJECTIVES: To evaluate the effectiveness and safety of two different intravenous methylprednisolone (IVMP) pulse doses in patients with severe microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). METHODS: We emulated a target trial using observational data from the nationwide registry in Japan. Patients with severe glomerulonephritis or diffuse alveolar haemorrhage were selected and pseudo-randomised into three groups using propensity score-based overlap weighting as follows: non-IVMP, IVMP 0.5 g/day, and IVMP 1.0 g/day. The primary outcome was all-cause death, and the secondary outcomes were composite all-cause death and kidney failure, severe relapse, and serious infection from 2 to 48 weeks after treatment initiation. To estimate the treatment effects, the Cox proportional hazard model and Fine-Gray subdistribution hazard model were used. RESULTS: In this emulated target trial, of 201 eligible patients (MPA, 175; GPA, 26), 6 (2.8%) died, 4 (2.0%) had kidney failure, 11 (5.3%) had severe relapse, and 40 (19.8%) had severe infections. Hazard ratios (HR) for IVMP 0.5 g/day and IVMP 1.0 g/day pulse groups compared with non-IVMP pulse were as follows: all-cause death = 0.46 (95% confidence interval [95%CI]: 0.07-2.81) and 0.07 (95%CI: 0.01-0.41); all-cause death/kidney failure = 1.18 (95%CI: 0.26-5.31) and 0.59 (95%CI: 0.08-4.52); subdistribution HRs for severe relapse = 1.26 (95%CI: 0.12-13.70) and 3.36 (95%CI: 0.49-23.29); and serious infection = 1.88 (95%CI: 0.76-4.65) and 0.94 (95%CI: 0.28-3.13). CONCLUSIONS: IVMP 1.0 g/day pulse may improve 48-week mortality in patients with severe MPA/GPA.

Late orbital radiotherapy combined with intravenous methylprednisolone in the management of long-lasting active graves' orbitopathy: a case report and literature review.

PURPOSE: To present a case and review the literature on Orbital Radiotherapy (OR) combined with intravenous methylprednisolone, focusing on its late application in patients with long-lasting active Graves' Orbitopathy (GO). Additionally, we suggest emerging perspective for future research in this context. METHOD: Relevant literature (randomized controlled studies, retrospective studies and reviews) was explored on PubMed from January 1973 to January 2024, searching "orbital radiotherapy" & "Graves disease". RESULTS: OR is a well-established second-line treatment for moderate-to-severe active GO, providing response rates comparable to glucocorticoids. Its anti-inflammatory effect makes OR particularly suitable for early active GO, and when combined with glucocorticoids, outcomes are synergistically improved. The emergence of the new Volumetric Modulated Arc Image-Guided Radiation Therapy (VMAT-IGRT) technique enables precise radiation delivery to the target, significantly reducing associated toxicity. This technological advancement enhances the feasibility of radiotherapy in benign diseases like GO. A retrospective study indicated that late OR in patients with long-lasting active GO may improve diplopia and visual acuity, decreasing disease activity. Our case report supports this conclusion. CONCLUSIONS: This report and literature review underscores the importance of considering late OR combined with intravenous methylprednisolone as a viable treatment option for GO patients with prolonged disease activity, emphasizing the crucial role of personalized therapy in managing GO. However, further investigations are warranted to validate this approach in cases of long-lasting active GO.

A Case of Acute Necrotizing Encephalopathy With Multiple Organ Failure Following COVID-19.

Neurological complications are frequent non-respiratory complications associated with coronavirus disease 2019 (COVID-19), and acute encephalopathy (AE) has been reported to occur in 2.2% of patients. Among many phenotypes of AEs, acute necrotizing encephalopathy (ANE) is associated with multiple organ failure (MOF), leading to severe neurological morbidity and mortality. A previously healthy seven-year-old girl presented with a one-day history of fever followed by 12 hours of vomiting and altered consciousness. On arrival, the patient was in shock. Blood tests revealed severe acute liver failure and kidney injury, accompanied by coagulopathy. The serum interleukin-6 levels were also elevated. PCR testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was positive. A head CT scan showed heterogeneous low-density areas in the bilateral thalamus, without brainstem involvement. She was diagnosed as ANE complicated with MOF (ANE severity score = 6). Intravenous methylprednisolone and therapeutic plasma exchange (TPE) were initiated with neurocritical care. After the introduction of TPE, hemodynamics improved rapidly, followed by gradual improvement in neurological manifestations. Upon follow-up after two months, no neurological or systemic sequelae were noted. Although further studies are needed, our case suggests that early immunomodulatory therapy and TPE may have contributed to the improvement in ANE and MOF associated with COVID-19.

Safety of non-standard regimen of systemic steroid therapy in patients with Graves' orbitopathy: a single-centre experience.

BACKGROUND: Graves' orbitopathy (GO) is an autoimmune disorder of the orbit and retro-ocular tissues and the primary extrathyroidal manifestation of Graves' disease. In moderate-to-severe and active GO iv glucocorticoids (GCs) are recommended as first-line treatment. The aim was to assess the safety profile of methylprednisolone administered intravenously for three consecutive days at 1 g in patients with active, moderate-to-severe or sight-threatening Graves' orbitopathy. METHODS: We retrospectively evaluated 161 medical records of patients with GO treated with high-dose systemic GCs in the Department of Endocrinology, Metabolic Disorders, and Internal Medicine in Poznan between 2014 and 2021. Clinical data included age, gender, laboratory results, activity and severity of GO, smoking status, disease duration, and presented side effects. RESULTS: The presence of mild side effects was observed during 114 (71%) hospitalizations. The most common complications were hyperglycemia (n = 95) and elevated aminotransferases (n = 31). Increased levels of aminotransferases were more likely observed in smokers and GO duration above 12 months. Based on the multivariate logistic regression, higher TRAb and CAS values were significantly associated with lower odds of hyperglycemia. In turn, the increased odds of elevated aminotransferases were significantly correlated with higher initial ALT levels, female gender, and GO duration above 12 months. In addition, the multidimensional correspondence analysis (MPA) showed that GO patients who declared smoking and had not L-ornithine L-aspartate applied demonstrated a higher probability of elevated aminotransferases. CONCLUSIONS: Active GO treatment with high-dose systemic GCs is not associated with serious side effects. Hyperglycemia is the most common steroid-induced complication.

Comparative effectiveness and safety of intravenous methylprednisolone and tacrolimus monotherapy in ocular myasthenia gravis with unsatisfactory prednisone responses: a retrospective study.

BACKGROUND: Oral prednisone has been recognized as the first-line therapy for the treatment of ocular myasthenia gravis (OMG). However, its long-term use is complicated by numerous adverse effects and is ineffective for some OMG patients in reaching remission. This study aimed to evaluate the effectiveness and safety of intravenous methylprednisolone (IVMP) and tacrolimus monotherapy for OMG patients with unsatisfactory responses to conventional prednisone therapy. METHODS: We retrospectively reviewed 57 OMG patients who had not achieved satisfactory improvement after prednisone therapy and thereby received IVMP or tacrolimus monotherapy for at least 6 months. Ocular symptoms were evaluated by the ocular-quantitative MG (QMG) score at each time point. A ≥ 2-point fall in ocular QMG score was defined as the cut-off point to indicate clinical improvement. Logistic regression analysis was performed to identify factors associated with the efficacy of IVMP at discharge. Adverse events were recorded. RESULTS: Both IVMP and tacrolimus monotherapy demonstrated significant clinical efficacy, with no statistical differences observed at the study endpoint. The proportions of patients who reached the cut-off point for efficacy evaluation were higher in the IVMP group than in the tacrolimus group (1, 3, and 6 months: 51.7% (15/29) vs 12.0% (3/25), p = 0.002; 69.0% (20/29) vs 40.0% (10/25), p = 0.033; 69.0% (20/29) vs 46.4% (13/28), p = 0.085, respectively). Multivariate logistics analysis showed that high ocular QMG scores at baseline indicated favourable responses to IVMP treatment (OR = 1.781; 95% CI 1.066-2.975; p = 0.028). All the adverse events were transient and tolerable. CONCLUSION: Our findings suggest that both IVMP and tacrolimus monotherapy hold promise as viable treatment options for OMG patients with unsatisfactory responses to oral prednisone. The study supports the safety and effectiveness of both therapies, with IVMP exhibiting faster improvement and favourable efficacy in patients with high ocular QMG scores.

Effect of high-dose intravenous methylprednisolone pulse (IVMP) therapy in the survival of patients with anti-melanoma differentiation-associated gene 5-related rapidly progressive interstitial lung disease: a retrospective analysis.

OBJECTIVES: To assess the impacts of high-dose intravenous methylprednisolone pulse (IVMP) therapy in survival and the occurrences of treatment-related infection of patients with anti-melanoma differentiation-associated gene 5 antibody-related rapidly progressive interstitial lung disease (MDA5-RPILD). METHODS: Patients with MDA5-RPILD from June 2017 to August 2022 in our hospital were retrospectively reviewed. IVMP therapy was defined as intravenous methylprednisolone (mPSL) 0.5g/day for 3 consecutive days during hospitalization or 7 days prior to admission and patients were divided into IVMP group and non-IVMP group based on who had ever received IVMP therapy. All-cause mortality and the incidence of adverse events during treatment were compared between the two groups. RESULTS: Sixty-four patients with MDA5-RPILD were enrolled. Among them, twenty-three (35.9%) patients had ever received IVMP therapy. The overall mortality was comparable between IVMP and non-IVMP group (IVMP group: 22/23, 95.7% vs. non-IVMP group: 38/41, 92.7%, p=0.11). And the incidence of treatment-related infections was also close (IVMP group: 21/23, 91.3% vs. non-IVMP group: 32/41, 78.0%, p=0.30). After adjustment for gender, age, smoking history, duration from symptom onset to diagnosis, and combination with steroid-sparing agent treatment, the Cox proportional hazards model showed that IVMP therapy was not associated with an improved survival (adjusted HR 1.10; 95% CI 0.57-2.13; p=0.77). CONCLUSION: Our study showed that the survival benefits and adverse events were comparable between IVMP-treated and untreated MDA5-RPILD patients. Future prospective trials are needed to investigate the optimal treatment regimen in MDA5-RPILD. Key Points • This observational study found that IVMP therapy may be not associated with an improved outcome in patients with MDA5-RPILD. • Treatment-related infections are common; however, the incidence of treatment-related infections had no difference between IVMP and non-IVMP group.

Lead Encephalopathy in a 73-year-old Man Manifesting as Acute Disturbance of Consciousness with a Unique Magnetic Resonance Imaging Appearance.

A 73-year-old man was admitted with Cheyne-Stokes respiration and progressive disturbance of consciousness over the course of a month. Cranial magnetic resonance imaging revealed signs suggestive of angioedema in the posterior limb of the internal capsule, external capsule, and subcortical white matter. Acute lead encephalopathy was diagnosed based on abnormally high plasma lead levels. After methylprednisolone pulse therapy followed by chelation therapy, the patient fully recovered. In this case, the angioedema with a distinctive magnetic resonance imaging appearance was attributed to the cytotoxic effects of lead on the nervous system, which responded well to methylprednisolone pulse therapy.

Plasma exchange for two patients with autoimmune GFAP astrocytopathy with rapid progression to respiratory failure: a case report.

Background: Patients with autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy can present with early neurological deterioration, but rapidly progressive respiratory failure is rarely reported. We present the cases of two patients with autoimmune GFAP astrocytopathy who experienced rapid progression to respiratory failure and were effectively treated using plasma exchange therapy. Case report: Two patients were diagnosed with autoimmune GFAP astrocytopathy. Their initial symptoms were consistent with those of previously observed cases of autoimmune GFAP astrocytopathy. However, they experienced rapid progression to respiratory failure due to their lesion location. Specifically, case 1 had lesions in the medulla oblongata, and case 2 had lesions in the high cervical spinal cord, which are both common sites of lesions causing respiratory failure. The patients did not respond well to intravenous methylprednisolone and intravenous immunoglobulin initially and could not be withdrawn from ventilator support. Fortunately, subsequent plasma exchange therapy led to significant clinical improvements and successful withdrawal from ventilator support. Discussion: Patients with autoimmune GFAP astrocytopathy can present with rapidly progressive respiratory failure. Early treatment with plasma exchange can be beneficial in withdrawing patients from ventilator support.

Childhood-onset systemic lupus erythematosus: characteristics and the prospect of glucocorticoid pulse therapy.

Childhood-onset systemic lupus erythematosus (cSLE) is an autoimmune disease that results in significant damage and often needs more aggressive treatment. Compared to adult-onset SLE, cSLE has a stronger genetic background and more prevalent elevated type I Interferon expression. The management of cSLE is more challenging because the disease itself and treatment can affect physical, psychological and emotional growth and development. High dose oral glucocorticoid (GC) has become the rule for treating moderate to severe cSLE activity. However, GC-related side effects and potential toxicities are problems that cannot be ignored. Recent studies have suggested that GC pulse therapy can achieve disease remission rapidly and reduce GC-related side effects with a reduction in oral prednisone doses. This article reviews characteristics, including pathogenesis and manifestations of cSLE, and summarized the existing evidence on GC therapy, especially on GC pulse therapy in cSLE, followed by our proposal for GC therapy according to the clinical effects and pathogenesis.

Krill's Disease: A Newer Management Option.

Purpose: To report a case of a young female who presented with scotoma in the right eye for few days. Case Report: Krill's disease or acute retinal pigment epithelitis (ARPE) is a self-limiting retinal disease with no specific treatment. Typical clinical and imaging features helped us to diagnose her with ARPE. Intravenous methylprednisolone (IVMP), which gives a rapid anti-inflammatory response, was advised. An SD-OCT scan post-injection showed a reduction in hyperreflectivity and height of lesion at day 3 and near total resolution by day 5. Conclusion: This case suggests rapid resolution of ARPE with the use of IVMP.

Efficacy and Safety of 6-Weekly versus 12-Weekly Intravenous Methylprednisolone in Moderate-to-Severe Active Thyroid-Associated Ophthalmopathy.

PURPOSE: To compare the efficacy and safety of 6-weekly and 12-weekly intravenous methylprednisolone (IVMP) regimens in moderate-to-severe, active thyroid-associated orbitopathy (TAO) patients. BASIC PROCEDURES: Retrospective comparative study of patients who received IVMP between January 2011 and July 2021 at the Thyroid Eye Clinic, the Chinese University of Hong Kong. Outcome measures included the 7-item clinical activity score (CAS), exophthalmos, extraocular muscle motility (EOMy), marginal reflex distance (MRD), best corrected visual acuity (BCVA), intraocular pressure (IOP), the requirement of additional treatment, and complications. MAIN FINDINGS: A total of 65 (63% (41/65) females) moderate-to-severe, active TAO patients aged 50 ± 13 (25-74) years received 6-weekly (n = 22) or 12-weekly (n = 43) IVMP. Sex, age, smoking status, and Graves' disease status were comparable in the two groups (all p > 0.05). CAS at week 6 (p = 0.0279), 12 (p = 0.00228), and 52 (p = 0.0228) were lower at each time for the 12-weekly group. Exophthalmos improved more at week 6 (p = 0.0453) and 12 (p = 0.0347) in the 12-weekly group. The improvement of diplopia, MRD1, MRD2, and EOMy were comparable between the two groups. More patients in the 6-weekly group (p = 0.00169) required additional treatments including IVMP+/-ORT. Patients in the 6-weekly group who did not require additional treatment had a lower presenting CAS (p = 0.0193) than those who required additional treatment. The total numbers of adverse events were comparable between the two groups.

Overlapping rheumatoid meningitis with anti-N-methyl-D-aspartate receptor encephalitis: A case report.

A 66-year-old woman in treatment for rheumatoid meningitis was found to be positive for anti-N-methyl-D-aspartate receptor (NMDAR) antibodies in the cerebrospinal fluid, and intravenous immunoglobulin improved her psychiatric symptoms. The co-existence of NMDAR antibodies should be considered in cases of poor response to treatments or atypical symptoms in rheumatoid meningitis.

Unilateral Autoimmune Encephalitis: A Case Report on a Rare Manifestation of Myelin Oligodendrocyte Glycoprotein Antibody Disease.

Myelin oligodendrocyte glycoprotein (MOG)-associated disease (MOGAD) is a rare, antibody-mediated inflammatory demyelinating disorder of the central nervous system (CNS) that has varying phenotypes. FLAIR (fluid-attenuated inversion recovery)-hyperintense Lesions in Anti-MOG-associated Encephalitis with Seizures (FLAMES) is a much rarer manifestation of cortical encephalitis encountered in MOGAD. We report a rare case of a nine-year-old girl who presented with a drop in her academic performance and right-sided Epilepsia partialis continua. Magnetic resonance imaging (MRI) of the brain detected evidence for unilateral (left) cortical encephalitis with peri-ictal juxtacortical edema. An electroencephalogram revealed a hemi-generalized poly spike and wave discharges in the left hemisphere, several of which correlated with myoclonic jerks. The cerebrospinal fluid (CSF) analysis was normal. Autoimmune workup resulted in a positive serum MOG-immunoglobulin G (IgG), which confirmed the diagnosis of FLAMES. The child showed an excellent clinical response to intravenous methylprednisolone and intravenous immunoglobulins therapy.

Early response to intravenous methylprednisolone therapy for restrictive myopathy in patients with thyroid eye disease.

PURPOSE: To report the therapeutic efficacy of intravenous methylprednisolone (IVMP) in patients with restrictive myopathy caused by thyroid eye disease (TED). METHODS: The present prospective uncontrolled study comprised 28 patients with TED and restrictive myopathy who presented with diplopia that had developed within 6 months before their visit. All patients were treated with IVMP for 12 weeks. Deviation angle, limitation of extraocular muscle (EOM) movement, binocular single vision score, Hess score, clinical activity score (CAS), modified NOSPECS score, exophthalmometric value, and the size of EOMs on computed tomography were evaluated. The patients were divided into two groups: those whose deviation angle had decreased or remained unchanged 6 months after treatment (group 1; n = 17) and those whose deviation angle had increased in that time (group 2; n = 11). RESULTS: The mean CAS of the whole cohort significantly decreased from baseline to 1 month and 3 months after treatment (P = 0.03 and P = 0.02, respectively). The mean deviation angle significantly increased from baseline to 1, 3, and 6 months (P = 0.01, P < 0.01, and P < 0.01, respectively). The deviation angle decreased in 10 (36%), remained constant in seven (25%), and increased in 11 (39%) of the 28 patients. When groups 1 and 2 were compared, no single variable was identified as a cause of deviation angle deterioration (P > 0.05). CONCLUSIONS: When treating patients with TED who have restrictive myopathy, physicians should be aware that some patients show worsening of the strabismus angle despite inflammation control with IVMP therapy. Uncontrolled fibrosis can result in motility deterioration.

Intravenous pulse methylprednisolone and corticosteroid-induced psychiatric disorders: A retrospective study.

OBJECTIVE: Corticosteroids can cause psychiatric symptoms known as corticosteroid-induced psychiatric disorders (CIPDs). Little is known regarding the relationship between intravenous pulse methylprednisolone (IVMP) and CIPDs. Therefore, we aimed to examine the relationship between corticosteroid use and CIPDs in this retrospective study. METHODS: Patients who were prescribed corticosteroids during their hospitalization at a university hospital and referred to our consultation-liaison service were selected. Patients diagnosed with CIPDs according to the ICD-10 codes were included. The incidence rates were compared between patients receiving IVMP and those receiving any other corticosteroid treatment. The association between IVMP and CIPDs was examined by classifying patients with CIPD into three groups according to the use of IVMP and timing of CIPD onset. RESULTS: Of the 14,585 patients who received corticosteroids, 85 were diagnosed with CIPDs, with an incidence rate of 0.6%. Among the 523 patients who received IVMP, the incidence rate of CIPDs was 6.1% (n = 32), which was significantly higher than that in patients receiving any other corticosteroid treatment. Among the patients with CIPDs, 12 (14.1%) developed CIPDs during IVMP, 19 (22.4%) developed CIPDs after IVMP, and 49 (57.6%) developed CIPDs without IVMP. There was no significant difference in the doses at the time of CIPD improvement among the three groups when we excluded one patient whose CIPD improved during IVMP. CONCLUSION: Patients receiving IVMP were more likely to develop CIPDs than those who did not receive IVMP. Furthermore, corticosteroid doses at the time of improvement of CIPDs were constant, regardless of IVMP use.

A single-center analysis of visual outcomes and associated factors after intravenous methylprednisolone treatment for dysthyroid optic neuropathy.

BACKGROUND: Dysthyroid optic neuropathy (DON) is a serious threatening vision loss in Graves' ophthalmopathy (GO). Although the European Group on Graves' Ophthalmopathy (EUGOGO) recommend intravenous methylprednisolone therapy for first line treatment, some characteristics predicting the response are still inconclusive. AIM: To study the efficacy of intravenous pulse methylprednisolone (IVMP) in treating dysthyroid optic neuropathy (DON) and to identify factors predicting poor response to the treatment. METHODS: All patients diagnosed with DON between January 2010 and December 2021 at Rajavithi Hospital, Thailand, receiving IVMP 1 g/ day for 3 consecutive days were analyzed. The efficacy at 1 week and 3, 6, 12-months in terms of improvement of best corrected visual acuity (BCVA) and proptosis were compiled. RESULTS: Of the entire 57 DON cases that received IVMP, 50.9% gained at least 0.2 Logarithm of the Minimum Angle of Resolution (logMAR) at 1 week, and the improvement from initial to 1-week BCVA was 0.63 ± 0.63 logMAR (p < 0.001) and the decrease in proptosis was 1.8 ± 1.36 mm (p < 0.001). The remaining 23 orbits underwent orbital decompression and were excluded from the long-term efficacy analysis. In the last 12-months' follow-up time, there was an improvement of BCVA (0.53 ± 0.47 logMAR) and proptosis (0.59 ± 0.66 mm) (both p < 0.001). At last visit, there was an improvement of BCVA (0.2 logMAR) and proptosis (2 mm) in 76.5, and 5.9% respectively. Significant predictive factors of poor treatment response were age ≥ 55 years (odds ratio [OR]: 8.28, 95% confidence interval [CI]: 1.368-50.121, p = 0.021); longer onset duration before treatment (OR: 5.10, 95%CI: 1.061-24.501, p = 0.042); and proptosis at baseline (OR: 9.31, 95%CI: 1.872-46.280, p = 0.006). The strongest risk factor for predicting poor response to IVMP was poor initial visual acuity (OR: 10.26, 95%CI: 1.363-77.234, p = 0.024). CONCLUSIONS: IVMP is effective for both short- and long-term treatment to improve visual acuity greater than proptosis. Older age, longer disease duration, poor initial visual acuity, and proptotic orbits were identified as risk factors for predicting poor response to IVMP treatment in Thai population. DON patients having those risk factors should be suspected, and treated early with IVMP to preserve their future vision.
