A case of naltrexone-induced acute eosinophilic pneumonia.

Acute eosinophilic pneumonia (AEP) is a rare cause of acute respiratory failure. Clinical presentations can range from dyspnoea, fever and cough, to rapidly progressive and potentially fulminant respiratory failure. While its exact cause is often unknown, associations with inhalational injuries and exposures to new medications have been described.We report a case of a middle-aged, non-smoking man with a history of alcohol use disorder. He presented with 4 days of shortness of breath that started hours after taking injectable naltrexone (Vivitrol). The patient had rapidly worsening hypoxaemia, necessitating emergent bronchoscopy with transbronchial biopsies and bronchoalveolar lavage which showed 66% eosinophils. The patient was intubated for the procedure and unable to get extubated due to worsening hypoxaemic respiratory failure with high fractional inspired oxygen requirements. Chest radiograph showed worsening lung infiltrates and with a high index of suspicion for AEP, he was started empirically on methylprednisolone. He had rapid improvement in his respiratory status and was extubated on day 5 of admission then discharged on day 8. Histopathological examination confirmed acute/subacute eosinophilic pneumonia. A 3-week post-discharge follow-up chest radiograph confirmed the full resolution of pulmonary infiltrates.Naltrexone-induced AEP is rare, with only six other cases reported in the literature. Careful history taking and prompt evaluation for AEP are important given the potential for rapid progression to acute hypoxic respiratory failure and the excellent response to steroid treatment.

Terminal ileitis: a rare gastrointestinal manifestation of IgA vasculitis in a child.

A girl in middle childhood was referred to the paediatric surgical team with acute colicky abdominal pain and bile-stained vomiting. This was preceded by a viral illness. Investigations revealed raised inflammatory markers, and imaging of the abdomen demonstrated ileal and jejunal thickening. Concerns were raised regarding whether she had inflammatory bowel disease. Endoscopy revealed gastritis and duodenitis, and colonoscopy was unremarkable. Video capsule endoscopy demonstrated ulcers in the jejunum and ileum.On day 8 of admission, she developed a symmetrical purpuric rash over both ankles leading to the diagnosis of Henoch-Schonlein-related ileitis. Multidisciplinary team working led to appropriate management of the patient and avoided surgery. Video capsule endoscopy enabled visualisation of the small bowel. She was managed with 5 days of methylprednisolone followed by oral steroids. She made a good recovery with no sequelae. This case highlighted that terminal ileitis is a rare complication of IgA vasculitis with a good prognosis.

A Phase I Trial Evaluating the Addition of Lenalidomide to Patients with Relapsed/Refractory Multiple Myeloma Progressing on Ruxolitinib and Methylprednisolone.

BACKGROUND: Ruxolitinib (RUX), an orally administered selective Janus kinase 1/2 inhibitor, has received approval for the treatment of myelofibrosis, polycythemia vera, and graft-versus-host disease. We have previously demonstrated the anti-multiple myeloma effects of RUX alone and in combination with the immunomodulatory agent lenalidomide (LEN) and glucocorticosteroids both pre-clinically and clinically. OBJECTIVE: This study aims to evaluate whether LEN can achieve clinical activity among patients with multiple myeloma progressing on the combination of RUX and methylprednisolone (MP). METHODS: In this part of a phase I, multicenter, open-label study, we evaluated the safety and efficacy of RUX and MP for patients with multiple myeloma with progressive disease who had previously received a proteasome inhibitor, LEN, glucocorticosteroids, and at least three prior regimens; we also determined the safety and efficacy of adding LEN at the time of disease progression from the initial doublet treatment. Initially, all subjects received oral RUX 15 mg twice daily and oral MP 40 mg every other day. Those patients who developed progressive disease according to the International Myeloma Working Group criteria then received LEN 10 mg once daily on days 1-21 within a 28-day cycle in addition to RUX and MP, which were administered at the same doses these patients were receiving at the time progressive disease developed. RESULTS: Twenty-nine subjects (median age 64 years; 18 [62%] male) were enrolled in this part of the study and initially received the two-drug combination of RUX and MP. The median number of prior therapies was six (range 3-12). The overall response rate from this two-drug combination was 31% and the clinical benefit rate was 34%. The best responses were 1 very good partial response, 8 partial responses, 1 minor response, 12 stable disease, and 7 progressive disease. The median progression-free survival was 3.5 months (range  0.5-36.2 months). The median time to response was 3.0 months. The median duration of response was 12.5 months (range 2.8-36.2 months). Twenty (69%) patients who showed progressive disease had LEN added to RUX and MP; all patients had prior exposure to LEN and all but one patient was refractory to their last LEN-containing regimen. After the addition of LEN, the overall response rate was 30% and the clinical benefit rate was 40%. The best responses of patients following the addition of LEN were 2 very good partial responses, 4 partial responses, 2 minor responses, 8 stable disease, and 4 progressive disease. The median time to response was 2.6 months (range 0.7-15.0 months). The median duration of response was not reached. The median progression-free survival following the addition of LEN was 3.5 months (range 0.3-25.9 months). CONCLUSIONS: For patients with multiple myeloma, treatment with RUX and MP is effective and well tolerated, and LEN can be used to extend the benefit of this RUX-based treatment. CLINICAL TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, NCT03110822, and is ongoing.

Mini-dose methotrexate combined with methylprednisolone for the initial treatment of acute GVHD: a multicentre, randomized trial.

BACKGROUND: There is an urgent unmet need for effective initial treatment for acute graft-versus-host disease (aGVHD) adding to the standard first-line therapy with corticosteroids after allogeneic haematopoietic stem cell transplantation (allo-HSCT). METHODS: We performed a multicentre, open-label, randomized, phase 3 study. Eligible patients (aged 15 years or older, had received allo-HSCT for a haematological malignancy, developed aGVHD, and received no previous therapies for aGVHD) were randomly assigned (1:1) to receive either 5 mg/m2 MTX on Days 1, 3, or 8 and then combined with corticosteroids or corticosteroids alone weekly. RESULTS: The primary endpoint was the overall response rate (ORR) on Day 10. A total of 157 patients were randomly assigned to receive either MTX plus corticosteroids (n = 78; MTX group) or corticosteroids alone (n = 79; control group). The Day 10 ORR was 97% for the MTX group and 81% for the control group (p = .005). Among patients with mild aGVHD, the Day 10 ORR was 100% for the MTX group and 86% for the control group (p = .001). The 1-year estimated failure-free survival was 69% for the MTX group and 41% for the control group (p = .002). There were no differences in treatment-related adverse events between the two groups. CONCLUSIONS: In conclusion, mini-dose MTX combined with corticosteroids can significantly improve the ORR in patients with aGVHD and is well tolerated, although it did not achieve the prespecified 20% improvement with the addition of MTX. TRIAL REGISTRATION: The trial was registered with clinicaltrials.gov (NCT04960644).

An updated systematic review of neuroprotective agents in the treatment of spinal cord injury.

This systematic review aims to summarize the findings from all clinical randomized trials assessing the efficacy of potential neuroprotective agents in influencing the outcomes of acute spinal cord injuries (SCI). Following the PRISMA guidelines, we conducted comprehensive searches in four electronic databases (PubMed, Scopus, Cochrane Library, and Web of Science) up to September 5th, 2023. Our analysis included a total of 30 studies. We examined the effects of 15 substances/drugs: methylprednisolone, tirilazad mesylate, erythropoietin, nimodipine, naloxone, Sygen, Rho protein antagonist, granulocyte colony-stimulating factor, autologous macrophages, autologous bone marrow cells, vitamin D, progesterone, riluzole, minocycline, and blood alcohol concentration. Notable improvements in neurological outcomes were observed with progesterone plus vitamin D and granulocyte colony-stimulating factor. In contrast, results for methylprednisolone, erythropoietin, Sygen, Rho Protein, and Riluzole were inconclusive, primarily due to insufficient sample size or outdated evidence. No significant differences were found in the remaining evaluated drugs. Progesterone plus vitamin D, granulocyte colony-stimulating factor, methylprednisolone, Sygen, Rho Protein, and Riluzole may enhance neurological outcomes in acute SCI cases. It is worth noting that different endpoints or additional subgroup analyses may potentially alter the conclusions of individual trials. Therefore, certain SCI grades may benefit more from these treatments than others, while the overall results may remain inconclusive.

Intravenous immunoglobulin for chronic inflammatory demyelinating polyradiculoneuropathy.

BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) causes progressive or relapsing weakness and numbness of the limbs, which lasts for at least two months. Uncontrolled studies have suggested that intravenous immunoglobulin (IVIg) could help to reduce symptoms. This is an update of a review first published in 2002 and last updated in 2013. OBJECTIVES: To assess the efficacy and safety of intravenous immunoglobulin in people with chronic inflammatory demyelinating polyradiculoneuropathy. SEARCH METHODS: We searched the Cochrane Neuromuscular Specialised Register, CENTRAL, MEDLINE, Embase, and two trials registers on 8 March 2023. SELECTION CRITERIA: We selected randomised controlled trials (RCTs) and quasi-RCTs that tested any dose of IVIg versus placebo, plasma exchange, or corticosteroids in people with definite or probable CIDP. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcome was significant improvement in disability within six weeks after the start of treatment, as determined and defined by the study authors. Our secondary outcomes were change in mean disability score within six weeks, change in muscle strength (Medical Research Council (MRC) sum score) within six weeks, change in mean disability score at 24 weeks or later, frequency of serious adverse events, and frequency of any adverse events. We used GRADE to assess the certainty of evidence for our main outcomes. MAIN RESULTS: We included nine RCTs with 372 participants (235 male) from Europe, North America, South America, and Israel. There was low statistical heterogeneity between the trial results, and the overall risk of bias was low for all trials that contributed data to the analysis. Five trials (235 participants) compared IVIg with placebo, one trial (20 participants) compared IVIg with plasma exchange, two trials (72 participants) compared IVIg with prednisolone, and one trial (45 participants) compared IVIg with intravenous methylprednisolone (IVMP). We included one new trial in this update, though it contributed no data to any meta-analyses. IVIg compared with placebo increases the probability of significant improvement in disability within six weeks of the start of treatment (risk ratio (RR) 2.40, 95% confidence interval (CI) 1.72 to 3.36; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 3 to 5; 5 trials, 269 participants; high-certainty evidence). Since each trial used a different disability scale and definition of significant improvement, we were unable to evaluate the clinical relevance of the pooled effect. IVIg compared with placebo improves disability measured on the Rankin scale (0 to 6, lower is better) two to six weeks after the start of treatment (mean difference (MD) -0.26 points, 95% CI -0.48 to -0.05; 3 trials, 90 participants; high-certainty evidence). IVIg compared with placebo probably improves disability measured on the Inflammatory Neuropathy Cause and Treatment (INCAT) scale (1 to 10, lower is better) after 24 weeks (MD 0.80 points, 95% CI 0.23 to 1.37; 1 trial, 117 participants; moderate-certainty evidence). There is probably little or no difference between IVIg and placebo in the frequency of serious adverse events (RR 0.82, 95% CI 0.36 to 1.87; 3 trials, 315 participants; moderate-certainty evidence). The trial comparing IVIg with plasma exchange reported none of our main outcomes. IVIg compared with prednisolone probably has little or no effect on the probability of significant improvement in disability four weeks after the start of treatment (RR 0.91, 95% CI 0.50 to 1.68; 1 trial, 29 participants; moderate-certainty evidence), and little or no effect on change in mean disability measured on the Rankin scale (MD 0.21 points, 95% CI -0.19 to 0.61; 1 trial, 24 participants; moderate-certainty evidence). There is probably little or no difference between IVIg and prednisolone in the frequency of serious adverse events (RR 0.45, 95% CI 0.04 to 4.69; 1 cross-over trial, 32 participants; moderate-certainty evidence). IVIg compared with IVMP probably increases the likelihood of significant improvement in disability two weeks after starting treatment (RR 1.46, 95% CI 0.40 to 5.38; 1 trial, 45 participants; moderate-certainty evidence). IVIg compared with IVMP probably has little or no effect on change in disability measured on the Rankin scale two weeks after the start of treatment (MD 0.24 points, 95% CI -0.15 to 0.63; 1 trial, 45 participants; moderate-certainty evidence) or on change in mean disability measured with the Overall Neuropathy Limitation Scale (ONLS, 1 to 12, lower is better) 24 weeks after the start of treatment (MD 0.03 points, 95% CI -0.91 to 0.97; 1 trial, 45 participants; moderate-certainty evidence). The frequency of serious adverse events may be higher with IVIg compared with IVMP (RR 4.40, 95% CI 0.22 to 86.78; 1 trial, 45 participants, moderate-certainty evidence). AUTHORS' CONCLUSIONS: Evidence from RCTs shows that IVIg improves disability for at least two to six weeks compared with placebo, with an NNTB of 4. During this period, IVIg probably has similar efficacy to oral prednisolone and IVMP. Further placebo-controlled trials are unlikely to change these conclusions. In one large trial, the benefit of IVIg compared with placebo in terms of improved disability score persisted for 24 weeks. Further research is needed to assess the long-term benefits and harms of IVIg relative to other treatments.

Methylprednisolone taper is an effective addition to multimodal pain regimens after total shoulder arthroplasty: results of a randomized controlled trial: 2022 Neer Award winner.

BACKGROUND: Perioperative corticosteroids have shown potential as nonopioid analgesic adjuncts for various orthopedic pathologies, but there is a lack of research on their use in the postoperative setting after total shoulder arthroplasty (TSA). The purpose of this study was to assess the effect of a methylprednisolone taper on a multimodal pain regimen after TSA. METHODS: This study was a randomized controlled trial (clinicaltrials.gov NCT03661645) of opioid-naive patients undergoing TSA. Patients were randomly assigned to receive intraoperative dexamethasone only (control group) or intraoperative dexamethasone followed by a 6-day oral methylprednisolone (Medrol) taper course (treatment group). All patients received the same standardized perioperative pain management protocol. Standardized pain journal entries were used to record visual analog pain scores (VAS-pain), VAS-nausea scores, and quantity of opioid tablet consumption during the first 7 postoperative days (POD). Patients were followed for at least one year postoperatively for clinical evaluation, collection of patient-reported outcomes, and observation of complications. RESULTS: A total of 67 patients were enrolled in the study; 32 in the control group and 35 in the treatment group. The groups had similar demographics and comorbidities. The treatment group demonstrated a reduction in mean VAS pain scores over the first 7 POD. Between POD 1 and POD 7, patients in the control group consumed an average of 17.6 oxycodone tablets while those in the treatment group consumed an average of 5.5 tablets. This equated to oral morphine equivalents of 132.1 and 41.1 for the control and treatment groups, respectively. There were fewer opioid-related side effects during the first postoperative week in the treatment group. The treatment group reported improved VAS pain scores at 2-week, 6-week, and 12-week postoperatively. There were no differences in Europe Quality of Life, shoulder subjective value (SSV), at any time point between groups, although American Shoulder and Elbow Surgeons questionnaire scores showed a slight improvement at 6-weeks in the treatment group. At mean follow-up, (control group: 23.4 months; treatment group:19.4 months), there was 1 infection in the control group and 1 postoperative cubital tunnel syndrome in the treatment group. No other complications were reported. CONCLUSIONS: A methylprednisolone taper course shows promise in reducing acute pain and opioid consumption as part of a multimodal regimen following TSA. As a result of this study, we have included this 6-day methylprednisolone taper course in our multimodal regimen for all primary shoulder arthroplasties. We hope this trial serves as a foundation for future studies on the use of low-dose oral corticosteroids and other nonnarcotic modalities to control pain after shoulder surgeries.

Methylprednisolone Does Not Enhance Paraoxonase 1 Activity During Cardiopulmonary Bypass Surgery-A Randomized, Controlled Clinical Trial.

OBJECTIVES: Cardiopulmonary bypass (CPB) is linked to systemic inflammatory responses and oxidative stress. Paraoxonase 1 (PON1) is an antioxidant enzyme with a cardioprotective role whose activity is decreased in systemic inflammation and in patients with acute myocardial and global ischemia. Glucocorticoids counteract the effect of oxidative stress by upregulating PON1 gene expression. The authors aimed to determine the effect of methylprednisolone on PON1 activity during cardiac surgery on CPB. DESIGN: Prospective, randomized, controlled clinical trial. SETTING: The University Medical Center Ljubljana, Slovenia. PARTICIPANTS: Forty adult patients who underwent complex cardiac surgery on CPB between February 2016 and December 2017 were randomized into methylprednisolone and control groups (n = 20 each). INTERVENTIONS: Patients in the methylprednisolone group received 1 g of methylprednisolone in the CPB priming solution, whereas patients in the control group were not given methylprednisolone during CPB. MEASUREMENTS AND MAIN RESULTS: The effect of methylprednisolone from the CPB priming solution was compared with standard care during CPB on PON1 activity until postoperative day 5. Correlations of PON1 activity with lipid status, mediators of inflammation, and hemodynamics were analyzed also. No significant differences were found between study groups for PON1 activity, high-density lipoprotein, and low-density lipoprotein in any of the measurement intervals (p > 0.016). The methylprednisolone group had significantly lower tumor necrosis factor alpha (p < 0.001) and interleukin-6 (p < 0.001), as well as C-reactive protein and procalcitonin (p < 0.016) after surgery. No significant difference was found between groups for hemodynamic parameters. A positive correlation existed between PON1 and lipid status, whereas a negative correlation was found between PON1 activity and tumor necrosis factor alpha, interleukin-6, and CPB duration. CONCLUSIONS: Methylprednisolone does not influence PON1 activity during cardiac surgery on CPB.

Bilateral retrobulbar optic neuritis combined with optic perineuritis associated with atezolizumab treatment for small cell lung carcinoma.

INTRODUCTION: Ocular immune-related adverse events (OirAEs) associated with novel cancer therapies of immune checkpoint inhibitors (ICIs) are emerging. Retrobulbar optic neuritis (ON) combined with optic perineuritis (OPN), associated with atezolizumab, has been rarely reported and has a unique clinical manifestation. CASE DESCRIPTION: A 67-year-old woman was diagnosed with small-cell lung cancer. As maintenance therapy, atezolizumab was administered continuously for 10 cycles for approximately 14 months. One week after the administration of the tenth dose of atezolizumab, the patient experienced a bilateral, successive painless visual decline. The fundus and the retinal nerve fiber layer revealed no abnormalities, but the ganglion cell of the macula disappeared loss. The concentric shrinking of the peripheral visual field of the left eye was noticed. Orbital MRI revealed bilateral optic nerve thickening and peripheral optic nerve sheath enhancement ("tram-track" and "doughnut" signs). Serology, cerebrospinal fluid results, and image examination ruled out common causes of vision decline, and the condition was identified as bilateral retrobulbar ON combined with OPN as a probable atezolizumab-related immune adverse event. Thereafter, atezolizumab was discontinued, and intravenous methylprednisolone pulse (IVMP) (160 mg/day for 5 days) plus intravenous immunoglobulin (20 g/day for 3 days) was administered. The patient's visual function considerably improved after three weeks. CONCLUSIONS: Retrobulbar ON and OPN associated with atezolizumab are rare side effects that are easily overlooked. Immune-related ON has unique features and requires early identification. The primary treatment for optic nerve irAEs is corticosteroids, but this is not standardized and should be used with caution.

Evolving trends in the surgical, anaesthetic, and intensive care management of acute spinal cord injuries in the UK.

PURPOSE: We surveyed the treatment of acute spinal cord injuries in the UK and compared current practices with 10 years ago. METHODS: A questionnaire survey was conducted amongst neurosurgeons, neuroanaesthetists, and neurointensivists that manage patients with acute spinal cord injuries. The survey gave two scenarios (complete and incomplete cervical spinal cord injuries). We obtained opinions on the speed of transfer, timing and aim of surgery, choice of anaesthetic, intraoperative monitoring, targets for physiological parameters, and drug treatments. RESULTS: We received responses from 78.6% of UK units that manage acute spinal cord injuries (33 neurosurgeons, 56 neuroanaesthetists/neurointensivists). Most neurosurgeons operate within 12 h for incomplete (82%) and complete (64%) injuries. There is a significant shift from 10 years ago, when only 61% (incomplete) and 30% (complete) of neurosurgeons operated within 12 h. The preferred anaesthetic technique in 2022 is total intravenous anaesthesia (TIVA), used by 69% of neuroanaesthetists. Significantly more intraoperative monitoring is now used at least sometimes, including bispectral index (91%), non-invasive cardiac output (62%), and neurophysiology (73-77%). Methylprednisolone is no longer used by surgeons. Achieving at least 80 mmHg mean arterial blood pressure is recommended by 70% neurosurgeons, 62% neuroanaesthetists, and 75% neurointensivists. CONCLUSIONS: Between 2012 and 2022, there was a paradigm shift in managing acute spinal cord injuries in the UK with earlier surgery and more intraoperative monitoring. Variability in practice persists due to lack of high-quality evidence and consensus guidelines.

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.

Dysthyroid optic neuropathy: a case series at a tertiary ophthalmic referral centre.

BACKGROUND/OBJECTIVES: To determine risk factors and treatment outcomes in dysthyroid optic neuropathy (DON) at a single tertiary ophthalmic centre. METHODS: Retrospective audit of DON patients who have received intravenous methylprednisolone (IVMP) therapy at Royal Victorian Eye and Ear Hospital, Melbourne, Australia from July 2015 to October 2021. RESULTS: Study included 24 patients (58% female) with an average age of 59.8 ± 14.7 years at DON diagnosis. Majority (92%) had Graves' hyperthyroidism and 77% had a smoking history. At diagnosis, average visual acuity (VA) of worse eye was LogMAR 0.46, and 48% had relative afferent pupillary defect. Proptosis (89%) and diplopia (73%) were most commonly present at diagnosis. 78% showed predominantly extra-ocular muscle enlargement, and apical crowding (52%) on radiology. 38% (n = 9/24) responded to IVMP alone, 58% (n = 14/24) progressed to surgical orbital decompression. The average total cumulative dose of IVMP during DON treatment was 6.8 ± 1.9 g. 29% required further treatment after IVMP and surgical decompression, 4 (17%) had additional radiotherapy, and three (13%) required immuno-modulatory therapy. Average final VA was LogMAR 0.207, with all patients having inactive TED at final follow-up (mean 1.7 years). In refractory DON cases, 71% retained VA ≥ 6/9 and 48% had DON reversal. CONCLUSIONS: DON patients typically present in late 50s, with a smoking history and predominant extra-ocular muscle enlargement. High-dose IVMP fully resolved DON in only 38%. A considerable proportion required urgent orbital decompression. Most patients retained good vision at final follow-up.

Comparison of oral versus intravenous steroid in the management of Bell's palsy: a systematic review and meta-analysis of randomized clinical trials.

BACKGROUND: Bell's palsy is a condition affecting cranial nerve VII that results in acute peripheral unilateral facial weakness or paralysis of unclear etiology. Corticosteroids are the primary therapy choice, because they improve outcomes. According to a recent study, prednisolone effectively treats Bell's palsy in the short and long term. This study aimed to assess the effectiveness and safety of Single-Dose Intravenous Methylprednisolone to Oral Prednisolone in treating Bell's palsy patients. METHODS: PRISMA statement guidelines were used to design and conduct this systemic review. MEDLINE, Cochrane Library, and EMBASE databases were used in our search. We conducted the database search in November 2022. RESULTS: Thirty-three publications were reviewed as a result of the literature review. Three studies were included in the meta-analysis after applying our criteria. 317 Bell's palsy patients were included in our study. Regarding complete recovery to grade 1 in 1 month, IV methylprednisolone was higher than oral prednisolone; (log OR = 0.52, 95% CI [0.08, 0.97], P = 0.022). However, at 3 months, the two groups had no significant difference. Patients with grade 4 Bell's palsy were more likely to fully recover to grade 1 in 1 month with IV methylprednisolone than with oral prednisolone (log OR = 0.73, 95% CI [0.19, 1.26], P = 0.008), but not for patients with grade 3 or grade 2 Bell's palsy. CONCLUSION: This study shows evidence that patients with Bell's palsy can fully recover to grade 1 in 1 month when IV methylprednisolone is used instead of oral prednisolone. At 3 months, however, there was no discernible difference between the two treatments. Within 3 days of the onset of symptoms, IV methylprednisolone treatment can be started, which may help patients recover fully to grade 1 in 1 month. However, administering IV methylprednisolone may not always have long-term advantages compared to oral prednisolone.

Single-dose rituximab plus glucocorticoid versus cyclophosphamide plus glucocorticoid in patients with newly diagnosed acquired hemophilia A: A multicenter, open-label, randomized noninferiority trial.

Acquired hemophilia A (AHA) is a rare but serious bleeding disorder. Randomized controlled trial (RCT) comparing the efficacy of immunosuppression therapy for AHA lacks. We conducted the first multicenter RCT aiming to establish whether the single-dose rituximab combination regimen was noninferior to the cyclophosphamide combination regimen. From 2017 to 2022, 63 patients with newly diagnosed AHA from five centers were randomly assigned 1:1 to receive glucocorticoid (methylprednisolone 0.8 mg/kg per day for the first 3 weeks and then tapered) plus single-dose rituximab (375 mg/m2 ; n = 31) or plus cyclophosphamide (2 mg/kg per day until inhibitor becomes negative, for a maximum of 5 weeks; n = 32). The primary outcome was complete remission (CR, defined as FVIII activity ≥50 IU/dL, FVIII inhibitor undetectable, immunosuppression tapered and no bleeding for 24 h without bypassing agents) rate measured within 8 weeks. The noninferiority margin was an absolute difference of 20%. Twenty-four (77.4%) patients in the rituximab group and 22 (68.8%) patients in the cyclophosphamide group achieved CR, which showed the noninferiority of the single-dose rituximab-based regimen (absolute difference = -8.67%, lower limit of the 95% confidence interval = -13.11%; Pnoninferiority = 0.005). No difference was found in the incidence of treatment-related adverse events. Single-dose rituximab plus glucocorticoid regimen showed similar efficacy and safety, without a reported risk of secondary malignancies or reproductive toxicity seen in cyclophosphamide, it might be recommended as a first-line therapy for AHA, especially in China where there is a young age trend in AHA patients. This trial was registered at ClinicalTrials.gov as #NCT03384277.

Methylprednisolone Following Minimally Invasive Lumbar Decompression: A Large Prospective Single-Institution Study.

STUDY DESIGN: Prospective randomized. OBJECTIVE: Intraoperative methylprednisolone is a common adjunct following microscopic laminectomy/microdiscectomy. The goal of epidural instillation is a rapid symptomatic reduction in irritation of neural elements. There is inconsistent data supporting its use intraoperatively. To understand whether this maneuver results in any clinical effect, we performed a multiyear prospective study. SUMMARY OF BACKGROUND DATA: Previous work has demonstrated equivocal effects on pain with a suggestion of an increased risk of complication. These studies tend to suffer from small sample sizes and short follow-ups. MATERIALS AND METHODS: Study obtained IRB approval. During the study period from 2013 to 2019, nearly equivalent numbers of patients who had received steroids during MIS decompressions were followed. Primary outcomes included pain (visual analog scale) and disability [Oswestry Disability Index (ODI)] at 2 weeks and 4 months. Secondary outcomes included complications, readmissions, and reoperation rates during the study period. RESULTS: Four hundred eighty-six patients were followed for a mean follow-up of 5.17 years. The index case was more likely to be a revision surgery in the steroid group. Across all patients, there was no difference in pain at 2 weeks or 4 months. Disability was reduced at 2 weeks in the steroid group (ODI: 16.71 vs . 21.02, P = 0.04) but not at 4 months. By subgroup analysis, this is largely explained by ODI reduction in patients with high preoperative ODI (13.00 vs . 43.43, P = 0.03). Patients in the steroid cohort were more likely to undergo subsequent spinal surgery during the study period. CONCLUSION: Methylprednisolone instillation is associated with a large, transient reduction in ODI for patients with high preoperative ODI; there is no measurable effect on pain. There is equivocal effect on risk of subsequent reoperation. This issue was clarified in peer review but changes did not make it to the abstract. Therefore, the technique is likely best reserved for patients with significant preoperative disability.

The role of plasmapheresis in severe acute disseminated encephalomyelitis with clinical findings of transverse myelitis.

INTRODUCTION: Acute disseminated encephalomyelitis is a rare acute demyelinating disease of the central nervous system (CNS). The pathogenesis remains unclear but is suspected to be autoimmune. High doses of methylprednisolone (HDMP) are currently considered standard of treatment. Plasmapheresis (PE) is typically given in steroid refractory cases. There is currently limited evidence supporting its use in ADEM. MATERIALS AND METHODS: We report a 16-year-old girl with ADEM who improved rapidly after initiating PE. RESULTS: The patient presented with acute onset of multifocal CNS symptoms, including encephalopathy, requiring intensive care unit management. Despite HDMP administration, her clinical condition continued to deteriorate. PE was therefore initiated on the same day as HDMP. Her clinical condition improved significantly following the first session. She was extubated and discharged from the intensive care unit the following day. CONCLUSION: HDMP combined with PE may be an effective first-line treatment in patients with fulminant ADEM.

Effect of preoperative single-dose methylprednisolone administration on early postoperative pain following retrograde intrarenal surgery.

PURPOSE: To evaluate the effect of preoperative single-dose methylprednisolone use on postoperative early pain after retrograde intrarenal surgery (RIRS). METHODS: Patients who had 10-20 mm solitary kidney stones and underwent RIRS procedures were included in this prospective cohort study between February 2022 and May 2023. Patients who were administered methylprednisolone at a dose of 1 mg/kg preoperatively were included in group 1 (n: 31), and the other first 90 patients who met the inclusion criteria and did not receive methylprednisolone before surgery were included in group 2 (n: 90). Demographic data, features of stone, postoperative pain at 1, 6, 12, 18, and 24 hour, the need for analgesics, changes in serum glucose levels, and the prevalence of postoperative fever were compared. RESULTS: Age, sex, stone laterality, localization, size, Hounsfield Unit, modified Satava scores, stone-free status, duration of the RIRS procedure, and duration of the ureteral access sheath were found to be similar between groups. Visual Analog Scale (VAS) scores at postoperative 1, 6, 12, 18, and 24 h were found to be statistically significantly lower in group 1 (p = .001, p = .001, p = .001, p = .001, and p = .001, respectively). Similarly, postoperative analgesic requirements were found to be significantly lower in group 1 (p = .048) with a similar postoperative fever rate and changes in serum glucose levels between groups. CONCLUSION: Giving a single dose of methylprednisolone at a dose of 1 mg/kg preoperatively for the RIRS procedure is safe and effective at preventing early pain and the need for analgesics after the RIRS procedure.
