Pulsed intravenous methylprednisolone combined with oral steroids as a treatment for poorly responsive type 2 amiodarone-induced thyrotoxicosis

OBJECTIVES

Amiodarone-induced thyrotoxicosis (AIT) affects up to 3% of treated patients. Type 2 AIT (AIT2) is a destructive thyroiditis and is usually treated with medium-high oral doses of prednisone. As AIT may worsen the underlying heart disease, a rapid control of thyroid function is desirable. We aimed to determine whether a combined intravenous methylprednisolone (IVMP) pulses therapy associated to prednisone in the interpulse period can represent an efficient and safe alternative to urgent total thyroidectomy in patients with AIT2 not responsive to prednisone alone.

DESIGN AND METHODS

Patients presenting with a severe AIT2 studied in a tertiary referral Center from August 2018 to April 2019. We included four patients requiring a rapid improvement of thyroid function for their underlying cardiac disorders. The baseline doses of oral prednisone (range: 5-12.5 mg/day) and IVMP (range: 250-500 twice a week) were determined according to the severity of the thyrotoxicosis and were titrated based on clinical response.

RESULTS

Combined treatment was effective in all patients in the prompt restoration of euthyroidism and no major adverse events were reported during the follow-up. In all cases, FT4 and FT3 levels normalized at 3-5 weeks of treatment. A permanent hypothyroidism was observed in one patient, 3 months after the discontinuation of treatment.

CONCLUSIONS

We report for the first time that the combined intravenous and oral steroid therapy is effective in patients with AIT2. The treatment is well tolerated and leads to a rapid improvement of thyroid function, avoiding urgent total thyroidectomy and favoring a quick functional recovery and rehabilitation of cardiac patients.

Transforaminal Versus Lateral Parasagittal Versus Midline Interlaminar Lumbar Epidural Steroid Injection for Management of Unilateral Radicular Lumbar Pain: A Randomized Double-Blind Trial

BACKGROUND

Epidural steroid injections (ESIs) are commonly used for management of lumbosacral radicular pain. Midline interlaminar (MIL) or transforaminal (TF) routes are commonly used. The TF route, although associated with higher delivery of drug to the ventral epidural space, has serious complications including spinal cord injury and permanent paralysis reported in literature. Therefore, there is a search for a technically better route with fewer complications and greater drug delivery into the ventral epidural space. Recently, a parasagittal interlaminar (PIL) approach has been defined.

OBJECTIVES

We conducted this study to compare therapeutic effectiveness of 3 techniques of ESIs in patients having unilateral lumbar radiculopathy. Further, effect of ESI on bone mineral density (BMD) and serum osteocalcin levels were studied.

STUDY DESIGN

Randomized double-blind trial.

SETTING

Pain clinic of a tertiary care hospital.

METHODS

Sixty-five patients were randomly allocated into group MIL, group PIL, and group TF to receive epidural injection with 80 mg of methylprednisolone and 2 mL of 2% lidocaine. Effective pain relief and improvement in disability were assessed using Visual Analog Scale (VAS) and Modified Oswestry Disability Questionnaire (MODQ) scores at 2 weeks, 4 weeks, 3 months, and 6 months, respectively. Patients with < 50% relief received additional injection. Primary outcome of study was effective pain relief at 6 months. Mean change in VAS and MODQ scores, BMD, and serum osteocalcin levels were secondary outcome assessed.

RESULTS

Patients having effective pain relief were significantly higher in group PIL (16 of 20 [80%]) and group TF (15 of 20 [75%]) compared with group MIL. Patients receiving ESI in group PIL and group TF showed significantly lower VAS scores than group MIL (P = 0.02, P = 0.50 at 3 months and P = 0.00, P = 0.02 at 6 months, respectively). Mean MODQ scores in group PIL and group TF were significantly lower than group MIL. However, group PIL and group TF did not significantly differ in MODQ scores. There was no significant change in serum osteocalcin and BMD, as assessed by dual energy x-ray absorptiometry scan at 3 months.

LIMITATIONS

The absence of a placebo control group, small sample size, and relatively short follow-up of 6 months were limitations.

CONCLUSIONS

PIL approach is equivalent to TF and superior to MIL approach in terms of effective pain relief and decrease in disability in patients with unilateral lumbar radiculopathy. This study showed no deleterious effect on BMD.

[Guillain-Barré syndrome with refractory optic neuropathy]

A 60-year-old woman with a 3-day history of ataxic gait, blurred vision, and upper extremity paresthesia was admitted to our hospital. She presented with severe visual disturbances (finger counting), ophthalmoplegia, neck weakness, and sensory ataxia. Serum anti-GQ1b antibody, anti-GM3 antibody, and anti-GD3 antibody were strongly positive, which might contribute to the pathogenesis. Since we suspected Guillain-Barré syndrome (GBS), intravenous immunoglobulin therapy (IVIg) and high-dose steroid therapy were administered; however, improvements in her visual acuity were minimal. Additional IVIg and high-dose steroid therapy resulted in limited visual acuity improvements. Therapeutic strategies for patients with GBS and refractory optic neuropathy remain controversial.

Efficacy and safety of pulsed intravenous methylprednisolone in early active thyroid eye disease

Introduction: The mainstay of therapy for active inflammatory phase of thyroid eye disease (TED) is immunosuppression. Patients in our centre with early active TED are treated with pulsed intravenous methylprednisolone (IVMP). Two different protocols are offered in our centre: High dose (1g/day for 3 days, monthly for 6 months), or EUGOGO protocol (500 mg weekly for six weeks, followed by 250 mg weekly for the next 6 weeks). Methods: A prospective cohort study of patients undergoing the two IVMP protocols was performed from January 2009 to May 2015. Main outcome measures were improvement of Clinical Activity Score (CAS) and International Thyroid Eye Disease (ITEDS) - VISA Inflammatory Index. Results: We had a total of 63 patients. Mean age was 43.1 ± 13.1years, females comprised 49.2% (n = 31), and 31 (49.2%) had a positive smoking history. Following IVMP, 65.0% (n = 41) had good response, 31.7% (n = 20) partial, and 3.3% (n = 2) poor. There were significant differences (p < 0.001) in CAS and ITEDS scores between pre-IVMP and post-IVMP visits, for both protocols. A higher proportion of patients receiving the modified EUGOGO protocol (58.3%) had persistent activity and required additional immunosuppression compared to those who underwent the high dose protocol (33.3%). Mild side effects were experienced by 5 (7.9%) and 3 (4.8%) patients at 3 and 6 months, respectively. There were no severe side effects, cardiovascular events or liver failure. Conclusion: With adequate screening and follow-up, six repeated cycles of high dose pulsed IVMP is an effective treatment for TED and can significantly reduce the morbidity associated with this debilitating condition. None of the 51 patients from the high dose protocol met with any serious side effects.

Efficacy of methylprednisolone on T-2 toxin-induced cardiotoxicity in vivo: A pathohistological study

Our aim was to compare the protective efficacy of two different formulations of methylprednisolone in T-2 toxin-induced cardiomyopathy. Methylprednisolone (soluble form, Lemod-solu^® and/or depot form, Lemod-depo^®, a total single dose of 40 mg/kg im) was given immediately after T-2 toxin (1 LD₅₀ 0.23 mg/kg sc). The myocardial tissue samples were examinated by using histopathology, semiquantitative and imaging analyses on day 1, 7, 14, 21, 28 and 60 of the study. Therapeutic application of Lemod-solu^® significantly decreased the intensity of myocardial degeneration and haemorrhages, distribution of glycogen granules in the endo- and perimysium, a total number of mast cells and the degree of their degranulation was in correlation with the reversible heart structural lesions (p <  0.01 vs. T-2 toxin). These changes were completely abolished by the therapeutic use of Lemod-solu^® plus Lemod-depo^® (p <  0.001 vs. T-2 toxin). Our results show that a significant cardioprotective efficacy of methylprednisolone is mediated by its anti-inflammatory activity.

Scalp EEG high frequency oscillations as a biomarker of treatment response in epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS)

PURPOSE

We investigated whether the presence of interictal scalp EEG high frequency oscillations (HFOs) in children with epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS) can predict seizure and cognitive outcome after steroid therapy.

METHODS

Twenty-two children with CSWS were prospectively enrolled and received methylprednisolone therapy. Interictal scalp HFOs, spike wave index (SWI) and intelligence quotient (IQ) were assessed before and after the treatment. The children were divided into two groups based on the early seizure reduction ratio at 2 weeks (≥50%, "response group"; otherwise "non-response group"). The "response group" was further divided into two subgroups ("relapse" and "non-relapse" subgroups) according to the late seizure outcome (after 3 months).

RESULTS

Interictal HFOs and electrical status epilepticus in sleep (ESES) (defined as SWI ≥ 85%) were detected in all children at the baseline. In the response with relapse group (n = 11), the detection ratio of HFOs was significantly higher than that of ESES at 2 weeks (81.2 vs. 27.3%), 3 months (90.9 vs. 36.4%), and 6 months (100 vs. 54.5%) post-therapy. In the non-response group (n = 4), both HFOs and ESES persisted in all children. The average IQ improved significantly only in the response with non-relapse group. The persistence of HFOs negatively correlated with both the average IQ, yet the persistence of ESES did not.

CONCLUSION

Interictal scalp HFOs may be a favorable non-invasive biomarker of predicting seizure and cognitive outcome in CSWS.

Management of an Adult with Goodpasture's Syndrome Following Brain Trauma with Extracorporeal Membrane Oxygenation: A Case Report

A 22-year-old man suffered from acute pulmonary hemorrhage and deteriorated renal function occurred within 3 days after traumatic brain injury. Mechanical ventilation cannot correct his severe hypoxemia, therefore, venoarterial extracorporeal membrane oxygenation (VA-ECMO) support was initiated and finally resolved his hypoxemia. Concomitantly, continuous renal replacement therapy was performed to improve his kidney function. Although no anti-glomerular basement membrane (anti-GBM) antibody was detected in serum, Goodpasture's syndrome was considered. After treated with methylprednisolone pulse therapy and plasmapheresis, his renal function was significantly improved. ECMO was eventually discontinued after 60 hours of treatment and extubated on day 10. He was discharged home with normal pulmonary and renal functions.

High dose intravenous methylprednisolone pulse therapy causes transient increase of serum calcium and phosphate levels

High and very high doses of intravenous methylprednisolone (IVMP) administered in pulses are the first-line treatment for active, moderateto- severe, as well as sight-threatening Graves' orbitopathy (GO). However, glucocorticoid therapy is associated with side effects, among others, it affects bone metabolism.

AIM

The aim of study was to assess the acute effects of high and very high doses of IVMP on calcium (Ca) and phosphate (P) balance in euthyroid patients with moderate-to-severe GO and sight-threatening GO due to dysthyroid optic neuropathy (DON).

MATERIALS AND METHODS

Thirty-six patients with active, moderate-tosevere GO were treated with twelve once-weekly pulses (with cumulative dose of 4.5 g IVMP) and 11 patients with DON received 3 intravenous pulses of 1.0 g IVMP on three consecutive days. We measured serum levels of Ca and P at baseline and on the following days after the beginning of the IVMP therapy.

RESULTS

We observed a significant increase in serum Ca level on the next day after the 1st IVMP pulse both in patients with moderate-tosevere GO and with DON. Then, on the day 3, the decrease of serum Ca was noticed. In patients with moderate-to-severe GO, on the day 2 serum P showed a significant increase and then, it returned to basal level on the day 3.

CONCLUSIONS

We observed a significant increase in serum Ca level on the next day after the 1st IVMP pulse both in patients with moderate-tosevere GO and with DON. Then, on the day 3, the decrease of serum Ca was noticed. In patients with moderate-to-severe GO, on the day 2 serum P showed a significant increase and then, it returned to basal level on the day 3.

Myositis as the initial presentation of panarteritis nodosa

A 47-year-old man presented with weight loss, bilateral calf pain, fever, hypertension, orchitis and oligoarthritis. Lab tests: anemia and elevated muscle enzymes. Resonance magnetic imaging: hyperintensity in gastrocnemius muscles (myositis). Histologic exam of the muscles: inflammatory infiltrate with atrophy and perifascicular regeneration. Treatment: methylprednisone (bolus) and cyclophosphamide. Muscle pain and swelling and difficulty in walking are common in panarteritis nodosa (PAN), whereas histologically demonstrated myositis is not. Even more rare is myositis as the initial presentation of this vasculitis.

Risk factors for cytomegalovirus infection in patients with antineutrophil cytoplasmic antibody-associated vasculitis

Aims

Cytomegalovirus (CMV) infection under immunosuppression sometimes causes death. This study aimed to elucidate risk factors for CMV infection in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV).

Methods

Patients with AAV who underwent remission induction treatment at Okayama University Hospital between 2006 and 2016 were retrospectively analyzed. The primary outcome was the development of CMV infection within 3 months.

Results

Of the 111 patients, 13 (11.7%) patients developed CMV infection. Patients with CMV infection were older (p = 0.030) and had a higher body mass index (p = 0.029) in comparison to those without CMV infection. A higher proportion had a severe form (p = 0.001) and granulomatosis with polyangiitis (GPA) (p = 0.001), as well as a higher Birmingham Vasculitis Activity Score (p = 0.018) and C-reactive protein (p = 0.018) levels at baseline. Using logistic regression analysis, severe form and GPA were independent risk factors (odds ratio [OR] = 9.68, 95% confidence interval [CI] = 1.92–60.23, and OR = 7.46, 95% CI = 1.46–47.60, respectively). In addition, patients with CMV infection were more likely than those without infection to be glucocorticoid-related diabetes mellitus (p = 0.025).

Conclusion

Our study highlights disease severity and subgroups of AAV as risk factors for CMV infection.

Long-term remarkable remission of SAPHO syndrome in response to short-term systemic corticosteroids treatment in an immunoglobulin E elevated patient: A case report

RATIONALE

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare auto-inflammatory disease with no standardized treatment. Systemic corticosteroids are only transiently effective, but long-term use would bring complications and would not bring long-term remission. Bone scintigraphy is a first-line method for systematic evaluation of osteoarticular lesions but seems to show an "imprinting" pattern.

PATIENT CONCERNS

A 31-year-old female patient presented significant palmoplantar pustulosis and nail lesion as well as typical tracer accumulation feature on bone scintigraphy with normal hypersensitivity C-reactive protein and erythrocyte sedimentation rate, but an elevated serum immunoglobulin E level.

DIAGNOSIS

The diagnosis was made by dermatological manifestations and classical sign in bone scintigraphy in accordance with the diagnostic criteria proposed in 1988.

INTERVENTIONS

Methylprednisolone was given with a primary dose of 40 mg/day for 1 week followed with a subsequent 20 mg/day oral prednisone for another 1 week and then reduced in a rate of 5 mg/week until the eventual cessation.

OUTCOMES

Long-term remarkable remission on clinical manifestations, MRI performance, and quantitative analysis of bone scintigraphy was achieved.

LESSONS

Identification of specific subtype of SAPHO patient according to skin and nail manifestations as well as immunoglobulin E level may guide the selection of short-term systemic corticosteroids strategy, leading to remarkable long-term remission. Besides, the lesions on bone scintigraphy can hardly disappear in SAPHO patients, and instead, the quantitative analysis of bone scintigraphy and MRI performances may better reflect the change of disease condition and serve as indicator for treatment efficiency.

Does Coadministration of Transforaminal Epidural Steroid Injection with Sedation Improve Patient Satisfaction? A Prospective Randomized Clinical Study

BACKGROUND

Transforaminal epidural steroid injection (TFESI) can be administered with or without sedation in clinical practice.

OBJECTIVES

The aim of this study was to compare both procedures in terms of patient and physician satisfaction, preoperative anxiety level, procedural pain level, and complications.

STUDY DESIGN

A prospective randomized trial.

SETTING

A university hospital interventional pain management center.

METHODS

The study included patients scheduled for single-level unilateral TFESI. The patients were randomized into 2 groups. The first group underwent TFESI without sedation, whereas the second group underwent TFESI with sedation. The Likert scale was used to determine the patient and physician satisfaction, and the Numeric Rating Scale (NRS-11) was used to determine the procedural pain level. Cases in which the procedure was to be repeated, the patient was questioned if they desired to undergo the procedure with the same technique.

RESULTS

A total of 64 patients, (31 [48.4%] in the sedation group) were included. In the sedation group, the patient and physician satisfaction were significantly higher (P = 0.0001), the periprocedural NRS-11 scores were significantly lower (P = 0.0001), and the rate of desire to have the intervention with the same technique was higher (P = 0.001). After the regression analysis, we reported that there was a significant correlation between being in the sedation group and NRS-11 procedure scores, the desire to have the same technique, and patient and physician satisfaction (odds ratio [OR], 0.341; OR, 0.648; OR, 0.329; OR, 0.514; P = 0.0001).

LIMITATIONS

Both patients and physicians were unblinded.

CONCLUSIONS

Coadministration of TFESI with sedation improves patient and physician satisfaction. Additionally, the low periprocedural pain level results in patients' demand for the intervention to be performed with sedation in the event of repetition of the procedure.

KEY WORDS

Patient satisfaction, transforaminal epidural steroid injection, sedation, physician satisfaction.

Single Intramuscular Methylprednisolone dose in Asthma and Chronic Obstructive Pulmonary Disease Patients on Discharge

OBJECTIVE

In this pilot study we aimed to evaluate the safety of a single intramuscular methylprednisolone (IM) injection at the time of discharge as a replacement for oral steroid therapy for patients in our population with asthma or chronic obstructive pulmonary disease (COPD).

METHODS

This proof-of-concept, open label clinical trial without randomisation was conducted at the Pulmonary Department of Ziauddin Hospital and University, Karachi from January 2018 to March 2018. Patients discharged after in-hospital treatment for exacerbations of either asthma or COPD were recruited for this study. Intramuscular injection of methylprednisolone was administered to these patients who were then followed-up after one week and one month. During that period, information was collected of the patients' self-report of any unscheduled emergency room visit, blood sugar and blood pressure control, symptoms suggestive of thrush, increase gastric acidity and weight gain. For the data analysis, frequency and percentages were calculated with SPSS version 21.

RESULTS

A total of 30 patients aged 52.83 ± 14.27 years were recruited for this pilot study. At one month follow-up, no unscheduled emergency room visits were observed in all of the study patients. Symptoms suggestive of oral thrush were recorded in only 2 (6.7%) patients and weight gain was reported by only 5 (16.7%). Controlled blood sugar and blood pressure was reported by all the patients. No incidence of nocturnal symptoms, awakening and dyspepsia were reported.

CONCLUSIONS

A single dose of methylprednisolone injection without any obvious side effects over one month among patients with asthma and COPD demonstrated a safe strategy for them.

Pre-emptive scalp infiltration with ropivacaine plus methylprednisolone versus ropivacaine alone for relief of postoperative pain after craniotomy in children (RP/MP vs RP): a study protocol for a randomised controlled trial

INTRODUCTION

Pre-emptive scalp infiltration with local anaesthetics is the simplest and most effective method to prevent postoperative incisional pain. However, local infiltration of an anaesthetic only provides relatively short-term pain relief. Methylprednisolone (MP) treatment, administered as an adjuvant at the wound site, has been shown to provide satisfactory pain management after lumbar laminectomy. However, there is no evidence regarding the efficacy of MP infiltration for the relief of postoperative pain after craniotomy. Currently, postoperative pain after craniotomy in children is undertreated. Therefore, we aim to investigate whether pre-emptive scalp infiltration with ropivacaine (RP) plus MP is superior to RP alone to improve postoperative pain after craniotomy in children.

METHODS AND ANALYSIS

The RP/MP versus RP trial is a prospective, single-centre, randomised, parallel-group study of 100 children aged 8-18 years undergoing intracranial surgery. Participants will be randomly allocated to receive pre-emptive scalp infiltration with either RP plus MP or RP alone. The primary outcome will be the cumulative fentanyl dose administered by patient-controlled intravenous analgesia within 24 hours postoperatively. The secondary outcomes will include postoperative Numerical Rating Scale scores, pain control satisfaction scores, length of stay and adverse events. Data will be analysed by the intention-to-treat principle.

ETHICAL APPROVAL AND DISSEMINATION

The study protocol has been approved by the Institutional Review Board of Beijing Tiantan Hospital Affiliated to Capital Medical University (Approval Number: KY 2018-066-02). The results will be disseminated in international academic meetings and published in peer-reviewed journals.

A pilot safety study of ublituximab, a monoclonal antibody against CD20, in acute relapses of neuromyelitis optica spectrum disorder

OBJECTIVE

To test the safety of ublituximab, a B cell depleting agent, as add-on therapy in the acute treatment of relapses of neuromyelitis optica spectrum disorder.

METHODS

We conducted an open-label phase 1b safety and proof-of-concept trial in 5 subjects with aquaporin-4 (AQP4)-immunoglobulin G (IgG) seropositive neuromyelitis optica spectrum disorder (NMOSD) who presented with acute transverse myelitis and/or optic neuritis. In addition to treating with 1 g of daily intravenous methylprednisolone, we infused a single dose of 450 mg of ublituximab within 5 days of relapse onset. The primary outcome measure was safety, and the secondary efficacy measures included change in Expanded Disability Status Scale (EDSS), durability of remission and B cell counts.

RESULTS

Five NMOSD subjects were enrolled, 4 of whom presented with acute transverse myelitis and 1 with acute optic neuritis. Ublituximab proved to be safe in all 5 NMOSD subjects, with no serious adverse events recorded. There were no opportunistic infections in any of the subjects; however, 1 subject experienced a transient leukopenia. EDSS scores dropped from a median of 6.5 on admission to 4.0 on 90-day follow up. Two subjects did not achieve total B cell depletion and relapsed within 3 months.

CONCLUSIONS

Ublituximab is a safe add-on therapy for NMOSD patients presenting with acute transverse myelitis and optic neuritis. Preliminary evidence suggests a promising benefit on durability of remission when B cell depletion is achieved. A placebo-controlled trial is necessary to confirm these findings.

CLASSIFICATION OF EVIDENCE

This study provides Class IV evidence that for patients with NMOSD with acute transverse myelitis or optic neuritis, ublituximab is safe and may improve neurological outcome.

A Case of Acquired Amegakaryocytic Thrombocytopenia with Anti-c-mpl Autoantibody: Comparison with Idiopathic Thrombocytopenic Purpura

Acquired amegakaryocytic thrombocytopenia (AAMT) is a rare disease that causes severe bleeding. The pathogenesis and treatment of AAMT have not yet been defined. We report the case of a 60-year-old woman diagnosed with AAMT, who presented with severe thrombocytopenia, gastroin-testinal bleeding, and significantly reduced bone marrow megakaryocytes. The patient was treated with methylprednisolone, cyclosporin, and intravenous immunoglobulin. After 2 weeks of treatment, her platelet count started to increase, and her bone marrow megakaryocyte count had normalized 3 months after diagnosis. At the time of diagnosis, the patient was seropositive for anti-c-mpl antibody but was seen to be seronegative once the platelet count recovered. In contrast, anti-c-mpl antibodies were not detected in the serum of 3 patients with idiopathic thrombocytopenic purpura. This case study suggests that anti-c-mpl antibody plays an important role in the development of AAMT, and that intensive immunosuppressive treatment is required for autoantibody clearance and recovery of megakaryocyte count.

[Case report of acute encephalopathy caused by enterohemorrhagic Escherichia coli infection in a 24-year-old woman]

Hemolytic uremic syndrome (HUS) and acute encephalopathy caused by enterohemorrhagic Escherichia coli infection occur commonly in children, whereas adult-onset disease is rare. Here we report the case of a 24-year-old woman who developed acute encephalopathy and recovered without sequelae. She initially developed abdominal pain and diarrhea. On day 6, O-157 Shiga toxin was detected in her stool and she developed HUS. On day 11, acute encephalopathy developed and she required artificial ventilation. She was treated with steroid pulse therapy and plasma exchange (PE) and then discharged on day 53 without any sequelae. Globotriaosylceramide, a Shiga toxin receptor, is more frequently present on the cellular membranes of women than on those of men. Therefore, it is conceivable that adult women are at a higher risk of developing acute encephalopathy than men. Steroid pulse therapy and PE may effectively treat acute encephalopathy by reducing inflammatory cytokine levels in the blood; therefore, these treatments should be proactively considered.

[Primary angiitis of the central nervous system with cerebral infarction and spinal hemorrhage]

A 61-year-old woman presented with acute intense lower back pain and weakness in her left leg. She also presented with throbbing headache on the same day. On admission, muscle weakness in her left leg, lower left quadrantanopia and left lower extremity deep sensory disturbance were observed. Laboratory data showed no coagulopathy and autoimmune antibody was negative. Cerebrospinal fluid examination showed bloody and inflammatory findings. Brain MRI revealed cerebral infarction with multiple intracranial arterial stenosis and convexal subarachnoid hemorrhage. Spinal MRI revealed spinal hemorrhage in the cervical, thoracic, and part of the lumbar spine. Because these lesions occurred simultaneously, we made a diagnosis of vasculitis. After high dose corticosteroids therapy was undertaken, the multiple arterial stenosis improved. Primary angiitis of the central nervous system is sometimes difficult to distinguish from reversible cerebral vasoconstriction syndrome in its initial stage; although symptoms, examination findings and treatment differ in both.

Pathological findings of progressive renal involvement in a patient with TAFRO syndrome

TAFRO syndrome (thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly) is thought of as an atypical type of idiopathic multicentric Castleman's disease. Interleukin-6, vascular endothelial growth factor (VEGF), and other cytokines are considered etiological factors. A 45-year-old woman was admitted to hospital with unknown fever and abdominal pain. She had thrombocytopenia, anasarca, proteinuria/hematuria, and slight hepatosplenomegaly. Based on her clinical course and laboratory data, she was diagnosed as having TAFRO syndrome. Kidney biopsy showed a membranoproliferative glomerulonephritis (MPGN)-like lesion containing lobulations of glomeruli, endothelial cell swelling, double contours of the glomerular basement membrane, and mesangiolysis. She was treated with methylprednisolone pulse (500 mg/day) and oral prednisolone (60 mg/day) therapy. The pleural effusion and ascites disappeared, and renal function normalized. Cyclosporine was added to prevent relapse. She went home, with no relapse 8 months after hospitalization. MPGN-like lesions were found frequently in patients with TAFRO syndrome in recent reports. However, there are few reports of pathologically confirmed cases of progressive renal involvement in TAFRO syndrome. The relationship between VEGF expression in renal tissue and the pathogenesis of renal injury in TAFRO syndrome was investigated in the present case.

Clinical Course and Treatment Response of Neuromyelitis Optica Spectrum Disease: An 8-Year Experience

PURPOSE

To report the clinical course and treatment response in a cohort of patients with neuromyelitis optica spectrum disorder (NMOSD) from a single referral center in Taiwan.

DESIGN

Case series.

METHODS

All NMOSD patients who received treatment and follow-up checks at National Taiwan University Hospital for at least 2 years between January 2008 and December 2016 were recruited. Demographic data and detailed characteristics of clinical course including acute episodes, maintenance therapies, and visual outcome were collected. Patients were examined every 6 months and during each episode of relapse.

RESULTS

A total of 96 patients were identified; of them, 68 (70.8%) had optic neuritis. Optic neuritis was the initial presentation of NMOSD in 44 patients. Among the patients with optic neuritis, 32.4% had recurrent optic neuritis within 1 year from the first episode. Compared with the group without optic neuritis, the group with optic neuritis had a younger age of presentation (34.4 ± 15.9 vs 42.4 ± 14.8 years, P = 0.02) and a higher 1-year recurrence rate (64.7% vs 17.9%, P < 0.001). Among the patients with optic neuritis, 51.5% had a final visual acuity of worse than 20/200. Multiple regression analysis showed that the presence of aquaporin-4-IgG antibodies and poor initial visual acuity were the risk factors for worse visual outcome.

CONCLUSIONS

In this study, patients with optic neuritis were younger and had a higher 1-year recurrence rate. Despite using steroid therapy during the acute phase and immunosuppressive agents as long-term treatment, visual prognosis was poor. Aquaporin-4-IgG antibodies and initial visual acuity were associated with final visual outcome.

Therapy of moderate-to-severe Graves' orbitopathy with intravenous methylprednisolone pulses is not associated with loss of bone mineral density

PURPOSE

To evaluate the influence of intravenous methylprednisolone (IVMP) pulse administration on bone mineral density (BMD) of the lumbar spine and the femoral neck in patients with moderate-to-severe Graves' orbitopathy (GO).

METHODS

Thirty-five patients with GO in euthyreosis were treated with 12 IVMP pulses (6 × 0.5 g, 6 × 0.25 g on a weekly schedule). Supplementation with 1.0 g of calcium and 800 IU of vitamin D was initiated in all patients before beginning therapy. BMD of the lumbar spine (L1-L4) and the femoral neck were assessed at baseline and after the last IVMP pulse using dual-energy X-ray absorptiometry. To determine differences in BMD between values at baseline and after treatment, we used the least significant change (LSC) methodology. LSC values were calculated to be 3 and 5% for the lumbar spine and the femoral neck, respectively. Change in BMD equal to or exceeding the LSC was assessed as either increase or decrease of BMD. We then compared pre-treatment and post-treatment mean BMD values at the lumbar spine and the femoral neck.

RESULTS

We did not observe a decrease of BMD at any site equal to or exceeding the LSC. We found an increase of BMD in at least one measurement site equal to or exceeding the LSC value in 43% of patients, mostly in the lumbar spine (31%). Mean femoral neck BMD did not change while mean lumbar BMD increased.

CONCLUSIONS

IVMP given in weekly intravenous pulses does not lead to loss of BMD of the lumbar spine and the femoral neck.

Autoimmune encephalitis with anti-IgLON5 and anti-GABAB-receptor antibodies: A case report

RATIONALE

Anti-IgLON5 disease is a complex neurological illness which is characterized by progressive sleep and movement disorders and defined by specific autoantibodies to IgLON5. We here describe the first case of a patient with coexisting anti-IgLON5 as well as anti-γ-aminobutyric acid B (GABAB)-receptor antibodies and predominant clinical features of anti-IgLON5 disease.

PATIENT CONCERNS

The patient initially presented with subacute symptoms of severe sleep disorder, gait stability, dysarthria, cognitive impairment, depressive episode and hallucinations.

DIAGNOSES

The patient was diagnosed with autoimmune encephalitis, based on clinical features and positive anti-IgLON5 antibodies in serum as well as in cerebrospinal fluid and anti-GABAB-receptor antibodies in serum only.

INTERVENTIONS

Initially, the patient was treated with high dosages of methylprednisolone and subsequently with plasmapheresis. Due to the lack of clinical improvement immunosuppressive treatment with intravenous cyclophosphamide was initiated.

OUTCOMES

Following the first year of cyclophosphamide treatment, neurological examination revealed an improvement in gait instability, visual and acoustic hallucinations and sleep disorder.

LESSONS

The case report demonstrates that anti-IgLON5 and anti-GABAB-receptor antibodies can coexist in the same patient whereas clinical leading symptoms are determined by those antibodies that were tested positive in cerebrospinal fluid.

Adult-onset Still's Disease as a Differential Diagnosis in Prolonged Fever: Diagnosis and Treatment Experience

Adult onset Still's disease is a rare systemic disease that may involve many organs and may mimick many disease such as infection, autoimmune disease, and also malignancy. The diagnostic approach and treatment strategies have not been well established due to its rarity; however, there are some diagnostic criteria that may help. We present a case of 36-year old man who experienced high prolonged fever which firstly thought as infection. He also had unilateral wrist and knee joint pain and maculopapular rash. Laboratory examination showed high leukocytes count with elevated polymorphonuclear neutrophil count, high platelet count, high ferritin level, and negative results of many infection markers (typhoid antibody, procalcitonin, malaria test, blood culture, urine culture, IgM pneumonia, ASTO, syphilis test, antiHIV, HBsAg, antiHCV, etc). Chest X-ray, joint X-ray, ultrasonography, and echocardiography showed normal result. The patient was then diagnosed with Adult-onset Still's disease and received intravenous methylprednisolone and the fever was disappeared in 3 days. Six months later the arthralgia appeared again, methotrexate was administered and the pain was then relieved.

Managing Pulmonary Toxicities Associated with Immunotherapy: A Case Discussion

Immunotherapy has changed the field of oncology around the world with the approval of immune checkpoint inhibitors for a number of tumor types over the last 5 years. However, immune-mediated adverse events can be challenging and difficult to treat, with one of the most dire consequences being immune-mediated pneumonitis. KEY POINTS: Rapid intervention and aggressive management for grade 3 or greater pneumonitisSlow taper of steroids and also recommend pneumocystis carinii pneumonia prophylaxisMonitor carefully for a pneumonitis flare with steroid taper, which can occur in the absence of resuming anti-programmed cell death protein 1 (PD-1) [1], and do not resume anti-PD-1 therapy until completely off steroids and no clinical or radiologic evidence of recurrenceConsider observation without anti-PD-1 resumption-in this case, durable response was maintained even without resuming anti-PD-1 therapy.

Biorelevant release testing of biodegradable microspheres intended for intra-articular administration

Characterization of controlled release formulations used for intra-articular (IA) drug administration is challenging. Bio-relevant synovial fluids (BSF), containing physiologically relevant amounts of hyaluronic acid, phospholipids and proteins, were recently proposed to simulate healthy and osteoarthritic conditions. This work aims to evaluate the performance of different controlled release formulations of methylprednisolone (MP) for IA administration, under healthy and disease states simulated conditions. Microspheres differed in grade of poly(lactide-co-glycolide) and in the theoretical drug content (i.e. 23 or 30% w/w). Their performance was compared with the commercially available suspension of MP acetate (MPA). Under osteoarthritic state simulated condition, proteins increased the MPA release and reduced the MPA hydrolysis rate, over 48 h. Regarding microspheres, the release patterns over 40 days were significantly influenced by the composition of BSF. The pattern of the release mechanism and the amount released was affected by the presence of proteins. Protein concentration affected the release and the concentration used is critical, particularly given the relevance of the concentrations to target patient populations, i.e. patients with osteoarthritis.

Efficacy and safety of adjunctive corticosteroids therapy for patients with severe community-acquired pneumonia: A systematic review and meta-analysis

BACKGROUND

The systemic use of corticosteroids for patients in severe community-acquired pneumonia (CAP) remains disputed in clinical practice. We undertook a systematic review and meta-analysis to assess the efficacy and safety of corticosteroids in patients with severe CAP.

METHODS

We searched MEDLINE (1946 to June 2018), EMBASE (1966 to June 2018), and the Cochrane Library database for randomized controlled trials (RCTs) conducted for severe CAP. The endpoints of the study included total mortality, length of intensive care unit (ICU) stay and mechanical ventilation.

RESULTS

Nine trials which contained 914 patients were included for final meta-analysis. Of the 488 patients in the corticosteroid group, there were 37 deaths (7.58%) and 56 deaths occurred in 426 patients in the control group (13.1%). Corticosteroid therapy was associated with a lower rate of all-cause mortality compared to control (odd ratio [OR] 0.63, 95% confidence interval [CI] 0.42-0.95, P = .03). Subgroup analysis was conducted to show that the drug type modified the effect of steroids for mortality rate: prednisolone or methylprednisolone therapy (OR 0.37, 95% CI 0.19-0.72) reduced total mortality, whereas hydrocortisone use did not (OR 0.90, 95% CI 0.54-1.49). We found the length of ICU stay was significantly shorter in the steroid group compared to control (MD -2.52 days, 95% CI -4.88 to -0.15; P = .04). And there was a reduction trend in the need for mechanical ventilation in corticosteroid group (OR 0.53, 95% CI 0.28-1.02; P = .06). There was no trend towards more adverse events in the corticosteroid arm compared to control (OR 0.92, 95% CI 0.58-1.47; P = .74).

CONCLUSION

Overall, adjunctive systemic corticosteroids therapy was effective and safe for patients with severe CAP. In addition, the effects of mortality may differ according to the type of corticosteroids.

Audiological outcomes in sudden sensorineural hearing loss with presumed inner ear hemorrhage

OBJECTIVE

To explore the hearing outcomes and prognostic factors in patients with sudden sensorineural hearing loss resulting from inner ear hemorrhage.

METHODS

42 patients (22 male and 20 female) were recruited from January 2016 to December 2017. Intravenous methylprednisolone and/or intratympanic corticosteroid were used as salvage therapy. The main measures included systemic risk factors and audiometric outcomes as proposed by American Academy of Otolaryngology-Head and Neck Surgery Hearing Loss Scale. All individuals were assessed at baseline, discharge (2 weeks post-treatment) and at 1, 3 and 6 months.

RESULTS

The mean ages of patients were 39.3 ± 14.8 yrs. Cardiovascular disorders were seen in 19.0-33.3% of cases. Restoration of hearing and speech discrimination abilities were assessed at the first month post-treatment versus initial levels (95.5 ± 15.5 vs. 109.2 ± 9.6 dB, p = 0.000; and 17.6 ± 24.4 vs. 1.3 ± 4.0%, p = 0.003, respectively). Word recognition scores continued to recover at month 6 (38.7 ± 35.4%, p = 0.000), whereas puretone ceased to change (90.8 ± 16.2 dB, p = 0.139). The final percentages of complete, partial and no recovery were 0%, 57.1% and 42.9% respectively. The prognosis was independent of accompanying systemic risk factors as analyzed in this study. Intratympanic intervention was associated with improved word recognition scores, although intravenous corticosteroid was not.

CONCLUSIONS

Profound sudden sensorineural hearing loss caused by inner ear hemorrhage often has an unsatisfactory prognosis. However, this cohort did experience partial audiological recovery with delayed onset. Immediate and effective intratympanic corticosteroid may have therapeutic potential for this intractable disease.

[A case of dementia with Lewy bodies and Hashimoto encephalopathy successfully treated with immunotherapy]

We report a 77-year-old woman suffering from dementia with Lewy bodies (DLB) who presented with Hashimoto encephalopathy. The patient began to mistakenly believe that another person was sleeping in her bed from approximately 70 years of age. She began to show symptoms of parkinsonism after 75 years of age. One night, the patient began to exhibit loitering behavior, and made incomprehensible comments while also exhibiting other abnormal behaviors. Clinical examination revealed rigidity and tremor of the limbs, as well as hallucination, abnormal speech and behavior. We first considered DLB. However, serum anti-thyroglobulin levels turned out to be elevated, indicating Hashimoto encephalopathy as well, and treated the patient with steroid pulse therapy. Her mental symptoms subsequently improved, but rigidity and tremor remained. ¹²³I-ioflupane SPECT demonstrated decreased accumulation in the bilateral caudal basal ganglia. Anti NH₂-terminal of α-enolase (NAE) antibody in the serum was positive. Therefore, we diagnosed the patient with the rare comorbidity of DLB and Hashimoto encephalopathy, successfully treated with immunotherapy.

[A case of meningoencephalitis associated with pembrolizumab treated for squamous cell lung cancer]

A 61-year-old man with squamous cell lung cancer was admitted to our hospital because of consciousness disturbance after treated with pembrolizumab. Cerebrospinal fluid examination revealed increased protein level (209.2 mg/dl) and lymphocytic pleocytosis(79/μl). He was diagnosed as a meningoencephalitis probably caused by an immune-related adverse event (irAE) of immune checkpoint inhibitors (ICIs), and was successfully treated with 1,000 mg methylprednisolone intravenously for 3 days twice and the consequent oral 1 mg/kg prednisolone. As ICIs, which activate the immune systems, are becoming important choices of the treatments against malignancies, we should keep the possibility of irAE in mind and, when needed, start the treatment as soon as possible.

High-dose intravenous methylprednisolone therapy in patients with Graves' orbitopathy is associated with the increased activity of factor VIII

PURPOSE

Venous thromboembolic events (VTE), with their life-threatening manifestation as pulmonary embolism, are potential adverse effects of intravenous methylprednisolone (IVMP) pulse therapy, partially due to a hypercoagulable state. The aim of the study was to analyze the influence of IVMP on selected hemostatic parameters in patients with moderate-to-severe Graves' orbitopathy (GO).

METHODS

26 euthyroid patients with GO were treated with 12 pulses of IVMP (6 × 0.5, 6 × 0.25 g every week). Hemostatic variables [factor (F) II, FV, FVII, FVIII, fibrinogen, antithrombin, activated partial thromboplastin time (aPTT), prothrombin time, international normalized ratio of prothrombin time, platelets and D-dimer] were analysed before, 24 and 48 h after 1st, 6th and 12th pulse.

RESULTS

A constant, transient trend in changes of some hemostatic variables was observed after all assessed pulses. We discovered an increase in median activity of FVIII 24 and 48 h after pulses, with a shortening of aPTT 24 h after each IVMP pulse (p < 0.00005). FVII decreased 24 h after each pulse (p < 0.0005 after 1st and 12th, p < 0.00005 after 6th). Fibrinogen level decreased 48 h after each pulse (P < 0.00005). We did not observe any statistically significant changes in hemostatic parameters in the long-term evaluation. Therapy was concluded in one patient after the 9th pulse due to pulmonary embolism.

CONCLUSIONS

The increase of FVIII activity is a consequence of treatment with IVMP and occurs after each pulse. In patients with additional risk factors of VTE, anticoagulation prophylaxis should be considered.

[A case of antisynthetase syndrome with anti-EJ antibody complicated by pericarditis]

A 69-year-old man was admitted with neck muscle weakness, symmetric proximal muscle weakness, skin rash and elevated serum creatine kinase levels. Muscle biopsy showed perifascicular necrosis and perimysial alkaline phosphatase activity. Chest CT revealed interstitial lung disease and colorectal cancer was diagnosed on colonoscopy. He was serologically positive for anti-EJ antibody, leading to the diagnosis of antisynthetase syndrome (ASS). After laparoscopic low anterior resection of the rectum, he received intravenous methylprednisolone (1,000 mg/d for 3 days) followed by oral prednisolone (50 mg/d). Although his muscle weakness improved after corticosteroid therapy, he developed pericardial effusion with resultant asymptomatic hypotension and arrhythmia possibly due to pericarditis. Corticosteroid monotherapy was insufficient to control the disease, and, we decided to use oral cyclosporin concurrently. After this combined therapy started, pericardial effusion and arrhythmia were improved. We should keep in mind that pericarditis can occur in patients with anti-EJ antibody-positive ASS, and early combined therapy with corticosteroid and immunosuppressive drugs for ASS may improve the patient's prognosis.

Factors associated with the efficacy of intravenous methylprednisolone in moderate-to-severe and active thyroid-associated ophthalmopathy: A single-centre retrospective study

OBJECTIVE

Intravenous methylprednisolone (IVMP) is recommended as the first-line treatment for moderate-to-severe and active thyroid-associated ophthalmopathy (TAO). This study aimed to identify potential predictors and establish a multivariable prediction model for the efficacy of IVMP therapy.

DESIGN

A single-centre retrospective study.

PATIENTS

A total of 302 consecutive patients diagnosed with moderate-to-severe and active TAO who underwent the full course of IVMP therapy were included.

METHODS

Participants were sequentially divided into the training set (n = 200) and the validation set (n = 102). Multivariate logistic regression analysis was used to identify the independent predictors and establish the predictive model.

RESULTS

In addition to the pretreatment clinical activity score (OR = 3.506, P < 0.001), elevated thyroid-stimulating hormone (TSH) levels during treatment (OR = 0.145, P = 0.005), pretreatment anti-TSH receptor antibody levels (OR = 0.061, P < 0.001) and duration of eye symptoms (OR = 0.878, P = 0.017), a significant relationship was found between therapeutic efficacy and the pretreatment triglyceride levels (OR = 0.090, P = 0.001). The prediction model showed good calibration and excellent discrimination, with an area under curve of 0.915 (P < 0.001) and 0.885 (P < 0.001) in the training and validation sets, respectively.

CONCLUSIONS

This study provides some novel insights into the factors associated with the efficacy of IVMP therapy. A multivariable prediction model has been established and validated to help determine the indication and prognosis of IVMP therapy. Moreover, several suggestions have been made in the management of TAO patients: early diagnosis and treatment (within 15 months); prompt restoration and maintenance of euthyroidism, especially meticulous control of TSH levels (≤5 μIU/mL); and regular monitoring of triglyceride levels.

[Elderly onset case of neuromyelitis optica that developed at the age of 90]

We report a case of neuromyelitis optica (NMO) that was diagnosed at the age of 90. After initially developing visual loss in the right eye, a patient was diagnosed with optic neuritis. Although treatment with methylprednisolone therapy provided relief, 3 months later she developed optic neuritis on the other side. Visual activity recovered after further administration of methylprednisolone. At the age of 91, she presented with muscle weakness of her left extremities. A cervical MRI revealed myelitis with a longitudinally extensive spinal cord lesion from the second to fifth cervical vertebrae. Anti-AQP-4 antibody was detected in her serum. She was diagnosed with NMO and treated with methylprednisolone therapy. Subsequently, she repeatedly relapsed within a short period, developing myelitis once and optic neuritis three times within a year. However, during each hospitalization period, methylprednisolone therapy proved to be effective for relieving her symptoms. As NMO patients with onsets over 60 years of the age have been reported, medical practitioners should be aware that disease onset can occur at extremely older ages, such as 90 years old.

Monocular Oculomotor Nerve Disorder Manifesting as Cranial Neuropathy in Systemic Lupus Erythematosus

We herein report the case of a patient who developed peripheral neuropathy of the bilateral lower legs that later became complicated with isolated oculomotor nerve disorder and was finally diagnosed as systemic lupus erythematosus (SLE). Based on the findings for oculomotor nerve paralysis and contrast-enhanced magnetic resonance imaging findings for the oculomotor nerve in the prepontine cistern, the isolated oculomotor nerve disorder was considered to be a manifestation of peripheral neuropathy. This oculomotor nerve disorder may contribute to the diagnosis of SLE and can be effectively treated with steroid pulse therapy. Reports of SLE manifesting as isolated oculomotor nerve paralysis are rare.

In vitro effects of three equimolar concentrations of methylprednisolone acetate, triamcinolone acetonide, and isoflupredone acetate on equine articular tissue cocultures in an inflammatory environment

OBJECTIVE To compare the effects of 3 equimolar concentrations of methylprednisolone acetate (MPA), triamcinolone acetonide (TA), and isoflupredone acetate (IPA) on equine articular tissue cocultures in an inflammatory environment. SAMPLE Synovial and osteochondral explants from the femoropatellar joints of 6 equine cadavers (age, 2 to 11 years) without evidence of musculoskeletal disease. PROCEDURES From each cadaver, synovial and osteochondral explants were harvested from 1 femoropatellar joint to create cocultures. Cocultures were incubated for 96 hours with (positive control) or without (negative control) interleukin (IL)-1β (10 ng/mL) or with IL-1β and MPA, TA, or IPA at a concentration of 10^-4, 10^-7, or 10^-10M. Culture medium samples were collected from each coculture after 48 and 96 hours of incubation. Concentrations of prostaglandin E₂, matrix metalloproteinase-13, lactate dehydrogenase, and glycosaminoglycan were determined and compared among treatments at each time. RESULTS In general, low concentrations (10^-7 and 10^-10M) of MPA, TA, and IPA mitigated the inflammatory and catabolic (as determined by prostaglandin E₂ and matrix metalloproteinase-13 quantification, respectively) effects of IL-1β in cocultures to a greater extent than the high (10^-4M) concentration. Mean culture medium lactate dehydrogenase concentration for the 10^-4M IPA treatment was significantly greater than that for the positive control at both times, which was suggestive of cytotoxicosis. Mean culture medium glycosaminoglycan concentration did not differ significantly. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that the in vitro effects of IPA and MPA were similar to those of TA at clinically relevant concentrations (10^-7 and 10^-10M).

Modified Siegel's criteria for sudden sensorineural hearing loss: Reporting recovery outcomes with matched pretreatment hearing grades

BACKGROUND

Sudden sensorineural hearing loss (SSNHL) is an emergency clinical otology condition defined as hearing loss greater than 30 dB over three consecutive frequencies within 72 h. We aimed to integrate pretreatment hearing grades with reports of treatment recovery outcomes of SSNHL using the modified Siegel's criteria.

METHODS

This was a retrospective cohort study comprising 110 patients with SSNHL seen between January 2014 and January 2015. The patients were treated with combined systemic and intra-tympanic steroid therapy. The audiometric results were recorded using the modified Siegel's criteria, including pretreatment hearing grades 1-5 (grade 1: hearing threshold under 25 dB, grade 2: hearing threshold 26-45 dB, grade 3: hearing threshold 46-70 dB, grade 4: hearing threshold 71-90 dB, grade 5: hearing threshold over 90 dB) and hearing recovery outcomes, consisting of complete recovery (CR), partial recovery (PR), slight improvement (SI), no improvement (NI) or non-serviceable ears (NS). Patients were further assessed based on the treatment modality (initial or salvage treatment) and duration of the treatment delay.

RESULTS

Hearing improvements (CR + PR + SI) were seen in 56 patients. Patients with pretreatment hearing grade 3 had the highest improvement rate (88.2% or 30/34). Patients who received the combined steroid therapy as the initial modality had a better overall hearing improvement rate than did the salvage group. Treatment within the first 14 days yielded a better hearing improvement rate than did late treatments of more than 14 days, especially in patients with a pretreatment hearing grade of 5.

CONCLUSION

Using the modified Siegel's criteria, we report the hearing recovery outcomes with matched pretreatment hearing grades of patients with SSNHL treated with combined intra-tympanic steroid therapy. Our results show the prognostic significance of pretreatment hearing grades in patients with SSNHL.

[A case of anti-myelin oligodendrocyte glycoprotein (MOG) and anti-N-methyl-D-aspartate (NMDA) receptor antibody-positive encephalitis with optic neuritis]

A 20-year-old female was hospitalized due to generalized seizure two weeks after an infection. She reported disorientation, neck stiffness and weakness in her legs. MRI FLAIR images and T₂WI on her first visit to our hospital showed hyperintense lesions in the bilateral cingulate gyrus and the medial region of the superior frontal gyrus. Gadolinium (Gd)-enhanced T₁WI showed enhancement in the upper part of the corpus callosum. Examination of her cerebrospinal fluid (CSF) revealed mildly elevated leucocytes. After the administration of high-dose intravenous methylprednisolone, her symptoms partially improved. However, MRI T₂WI at 16 days after admission showed a lesion with a peripheral hypointense rim in the left side of the cingulate gyrus, which had ring enhancement on contrast CT. FLAIR images at 28 days after admission showed the hyperintense lesion spreading in the subcallosal area and the brainstem, and coronal short inversion time inversion recovery (STIR) images demonstrated bilateral optic neuritis. She was treated with steroid pulse therapy and plasma exchange. Thereafter her symptoms improved. The patient's CSF at 27 days after admission tested positive for anti-myelin oligodendrocyte glycoprotein (anti-MOG) antibodies and anti-N-methyl-D-aspartate (anti-NMDA) receptor antibodies. Encephalitis with optic neuritis in a patient with both anti-MOG and anti-NMDA receptor antibodies is very rare. Coexistence of multiple antibodies in the same patient may contribute to the diversity of autoimmune diseases associated with anti-MOG antibodies or anti-NMDA receptor antibodies.

The clinical and cost-effectiveness of corticosteroid injection versus night splints for carpal tunnel syndrome (INSTINCTS trial): an open-label, parallel group, randomised controlled trial

BACKGROUND

To our knowledge, the comparative effectiveness of commonly used conservative treatments for carpal tunnel syndrome has not been evaluated previously in primary care. We aimed to compare the clinical and cost-effectiveness of night splints with a corticosteroid injection with regards to reducing symptoms and improving hand function in patients with mild or moderate carpal tunnel syndrome.

METHODS

We did this randomised, open-label, pragmatic trial in adults (≥18 years) with mild or moderate carpal tunnel syndrome recruited from 25 primary and community musculoskeletal clinics and services. Patients with a new episode of idiopathic mild or moderate carpal tunnel syndrome of at least 6 weeks' duration were eligible. We randomly assigned (1:1) patients (permutated blocks of two and four by site) with an online web or third party telephone service to receive either a single injection of 20 mg methylprednisolone acetate (from 40 mg/mL) or a night-resting splint to be worn for 6 weeks. Patients and clinicians could not be masked to the intervention. The primary outcome was the overall score of the Boston Carpal Tunnel Questionnaire (BCTQ) at 6 weeks. We used intention-to-treat analysis, with multiple imputation for missing data, which was concealed to treatment group allocation. The trial is registered with the European Clinical Trials Database, number 2013-001435-48, and ClinicalTrial.gov, number NCT02038452.

FINDINGS

Between April 17, 2014, and Dec 31, 2016, 234 participants were randomly assigned (118 to the night splint group and 116 to the corticosteroid injection group), of whom 212 (91%) completed the BCTQ at 6 weeks. The BCTQ score was significantly better at 6 weeks in the corticosteroid injection group (mean 2·02 [SD 0·81]) than the night splint group (2·29 [0·75]; adjusted mean difference -0·32; 95% CI -0·48 to -0·16; p=0·0001). No adverse events were reported.

INTERPRETATION

A single corticosteroid injection shows superior clinical effectiveness at 6 weeks compared with night-resting splints, making it the treatment of choice for rapid symptom response in mild or moderate carpal tunnel syndrome presenting in primary care.

[Guillain-Barré syndrome associated with acute hepatitis A-A case report and literature review]

A 44-year-old female developed acute hepatitis A (HA) 5 weeks after ingesting raw oysters. She developed ascending motor weakness, bilateral peripheral facial nerve palsy, and bulbar symptoms. A diagnosis of demyelinating Guillain-Barré syndrome (GBS) was made on the basis of her clinical manifestations and the results of a nerve conduction study. The patient showed improvement following combination treatment with intravascular immunoglobulin and high dose methylprednisolone. No antibodies against specific gangliosides, sulfated glucuronyl paragloboside (SGPG), or sulfatide were detected. HA virus (HAV) RNA was isolated from her serum and its full-length genome sequence was determined. It revealed a homology of 99.9% or more with HAV genotype IA (HAV-IA) of the 2014 outbreak. No mutant virus RNA was detected.

Blood Pressure Profile and N-Terminal-proBNP Dynamics in Response to Intravenous Methylprednisolone Pulse Therapy of Severe Graves' Orbitopathy

Hypercortisolemia is associated with increased risk of hypertension. Natural and synthetic glucocorticoids (GCs) have different effects on blood pressure (BP). The effect of synthetic GCs on BP depends on the dose, treatment duration, type of GCs, and route of administration. Intravenous methylprednisolone (IVMP) pulse therapy is the first line of treatment for severe Graves' orbitopathy (GO). The aim of this study was to evaluate influence of IVMP pulses on BP and N-terminal pro-brain natriuretic peptide (NT-proBNP) dynamics. A total of 32 patients with GO were treated with one IVMP pulse every week for 12 weeks. We performed 48-h BP monitoring (24-h before and 24-h after IVMP) and measured NT-proBNP before, 24 h, and 48 h after the 1st, 6th, and 12th IVMP pulse. Mean BP did not change after any of the pulses. We did not observe an increase in maximal systolic BP or mean nocturnal BP, except after the last pulse. Additionally, the dipping phenomenon was less frequent after the last pulse. We found a significant increase in median NT-proBNP levels after all analyzed pulses. Our study suggests that IVMP may have an unfavorable cumulative effect on BP. Variation in NT-proBNP concentration indicates a compensatory effect of brain natriuretic peptide secretion.

Efficacy and Safety of Low-to-Moderate Dose Oral Corticosteroid Treatment in Ocular Myasthenia Gravis

PURPOSE

To evaluate the response to corticosteroid therapy as a primary treatment for ocular myasthenia gravis.

METHODS

Patients diagnosed as having ocular myasthenia gravis by an acetylcholine receptor binding antibody test between January 2011 and September 2015 were included in the study and started receiving treatment with a corticosteroid. Patients with a blowout fracture, hyperthyroidism, diabetes mellitus, hypertension, cardiovascular disease, or history of strabismus surgery were excluded. Disappearance of diplopia and ptosis were considered a response to treatment.

RESULTS

Methylprednisolone therapy was administered to 29 patients (19 men and 10 women; average age: 49 ± 16.5 years) as an initial treatment. A total of 6 patients were lost to follow-up. Twenty-three of 29 patients (82.6%) were regarded as having presented a response to treatment. The average treatment duration was 3 weeks for patients responding to primary treatment. Eight patients complained of adverse effects from steroid therapy such as heartburn, insomnia, weight gain, and myalgia.

CONCLUSIONS

A corticosteroid could be considered as an initial treatment for patients diagnosed as having ocular myasthenia gravis by an acetylcholine receptor binding antibody test. [J Pediatr Ophthalmol Strabismus. 2018;55(5):339-342.].

Acute allograft rejection in liver transplant recipients: Incidence, risk factors, treatment success, and impact on graft failure

Objective This study was performed to identify risk factors for acute cellular rejection after liver transplantation (LT). Methods Consecutive LT recipients who underwent surgery in our institution from 2002 to 2015 were retrospectively evaluated. Results In total, 176 patients were eligible for statistical analysis. During a mean observation period of 61.1 ± 36.3 months, 43 episodes of acute rejection were evident. Of these, 34 (79.0%) were responsive to methylprednisolone, 3 (7.0%) were treated by adjusting the dosage of immunosuppressive agents, and 6 (14.0%) were methylprednisolone-resistant and treated using anti-thymocyte globulin. Biliary complications (odds ratio [OR] = 4.89, 95% confidence interval [CI] = 2.00-11.98); donor-negative, recipient-positive CMV mismatch (OR = 9.88, 95% CI = 1.18-82.36); sex mismatch (OR = 3.16, 95% CI = 1.31-8.10); and sex mismatch with a female donor (OR = 3.00, 95% CI = 1.10-7.58) were identified as significant risk factors for acute graft rejection after LT. Conclusion In patients who develop acute cellular rejection after LT, biliary complications should be evaluated as a potential cause. Most acute rejections after LT respond to bolus corticosteroid therapy.

Long-term adverse event: inflammatory orbitopathy induced by pembrolizumab in a patient with metastatic melanoma

The recent advent of immune checkpoint inhibitors (ICI), including anti-programmed cell death 1 protein (anti-PD-1) agents has revolutionized the therapeutic approach of metastatic malignancies. Yet, ICI can disrupt immune tolerance resulting in enhanced immune activation in normal tissues with significant toxicity. A dysregulated activation of T-cells directed to normal tissues stands as the main mechanism of immune-related adverse events (irAE). To date, only two cases of immune-related inflammatory orbitopathy related to anti-PD-1 agents have been reported. This rare immune adverse event usually occurred early after ICI initiation. Here, we report the first case of late inflammatory orbitopathy occurring in a melanoma patient treated with pembrolizumab. Consequently, the occurrence of irAE under ICI should be monitored, even late after treatment instauration.

[Efficacy and Safety of Salvage ESHAP Chemotherapy for Recurrent/Refractory PCNSLs]

BACKGROUND

Primary central nervous system lymphoma(PCNSL)is a primary brain tumor, which appears commonly and occupies around 4.6% of all primary brain tumors. The standard therapy for this tumor is high-dose methotrexate chemotherapy(HD-MTX)and whole-brain irradiation. No salvage therapies for HD-MTX therapy-refractory or recurrent PCNSLs have been standardized. In our institution, ESHAP therapy(high-dose cytarabine:2,000mg, cisplatin:25mg/m², etoposide:40mg/m², methylprednisolone:500mg)was administered as a secondary chemotherapy, and the efficiency was examined.

METHODS

We administered ESHAP therapy as secondary chemotherapy for patients with refractory/recurrent PCNSL after HD-MTX therapy. Patients with PCNSL who were diagnosed and treated at our institute since 1996 were retrospectively studied. Clinical evaluations were performed based on Karnofsky Performance Status and overall survival, and the effect of ESHAP therapy was evaluated using the Response Assessment in Neuro-Oncology criteria.

RESULTS

The number of patients with refractory/recurrent PCNSLs were 18(28-77 years of age, median age of 58.5 years). The response rate(RR)after the first course of salvage ESHAP therapy was 77.8%(14 cases), and complete response(CR)was achieved in 6 cases. The RR after the final course of ESHAP therapy was as high as 61.1%(11 cases), and 4 patients retained CR status. In patients with refractory PCNSL who were treated with HD-MTX, the RR in the final course of salvage ESHAP therapy was as high as 77.8%(7 cases), and 3 patients retained CR status during the periods. The occurrence rate of Grade 3 or higher adverse events, according to the Common Terminology Criteria for Adverse Events version 4.0, was 66.7%(12 cases);all events that were associated with blood and lymphatic system disorders were quickly alleviated, and no fatal adverse events occurred.

CONCLUSION

In this study, we retrospectively examined the efficacy of ESHAP therapy as a secondary chemotherapy for patients with refractory/recurrent PCNSL after receiving HD-MTX therapy. Based on our findings, we suggest that ESHAP therapy should be considered as an encouraging secondary chemotherapy for patients with refractory/recurrent PCNSL.

Steroid therapy in children with fulminant hepatitis A

Fulminant hepatic failure is a life-threatening disease. Hepatitis A virus (HAV) can cause fulminant hepatic failure and death in about 0.2% of cases. Extensive destruction of infected hepatocytes by immune-mediated lysis is thought to be the cause. We aimed to evaluate the use of steroid therapy in children with fulminant HAV. This study included 33 children with fulminant HAV in two groups. Steroid group: comprised of 18 children who received prednisolone (1 mg/kg/d) or its equivalent dose of methylprednisolone, and the nonsteroid group: comprised another 15 children who did not receive steroid therapy. Age and sex were matched for both groups (P > .05), and they were comparable regarding baseline clinical and laboratory characteristics. Of the steroid group, 15 patients survived and 3 died, while in the nonsteroid group, 4 patients survived and 11 died (P = .001). Of the living patients, 15 of 19 (78.9%) received steroids while only 3 of 14 (21.4%) of the dead patients received steroids (P = .001). Stepwise regression analysis showed that steroid therapy was the only independent variable associated with recovery (P = .001). Steroid therapy in children with fulminant HAV associated significantly with improved outcome and survival. Future studies on a larger population size are strongly recommended.
