Elevated intraocular pressure in children with acute lymphoblastic leukaemia: A prospective study.

Most childhood acute lymphoblastic leukaemia (ALL) protocols include high-dose steroid therapy. However, the known potential of high-dose steroids to significantly elevate intraocular pressure (IOP) and lead to glaucomatous optic neuropathy has not been intensively investigated in children with ALL. Moreover, as children with ALL do not routinely undergo IOP measurements, the need for IOP monitoring and therapy is unknown. We prospectively measured IOP in 90 children with newly diagnosed ALL attending a tertiary paediatric haematology/oncology centre, at diagnosis and at the middle and end of induction therapy. Ocular hypertension (IOP > 21 mm Hg) at any time point was documented in 64 children (71%), and the prevalence increased during induction. Thirty-six children (40%) had elevated IOP at ALL diagnosis before therapy initiation, and stratification to non-standard ALL was a risk factor. IOP reduction therapy was administered to 13 children (14%); none required surgery. Values normalised in all cases. On multivariate logistic regression analysis, dexamethasone therapy was a significant risk factor for ocular hypertension. High body mass index was an additional risk factor in children with elevated IOP at ALL diagnosis. Routine evaluation of IOP during steroid therapy is very important in children with ALL to ensure early intervention which may prevent permanent ocular damage.

High-dose steroids in high pain responders undergoing total knee arthroplasty: a randomised double-blind trial.

BACKGROUND: Total knee arthroplasty (TKA) is associated with moderate-to-severe postoperative pain despite multimodal opioid-sparing analgesia. Pain catastrophising or preoperative opioid therapy is associated with increased postoperative pain. Preoperative glucocorticoid improves pain after TKA, but dose-finding studies and benefit in high pain responders are lacking. METHODS: A randomised double-blind controlled trial with preoperative high-dose intravenous dexamethasone 1 mg kg-1 or intermediate-dose dexamethasone 0.3 mg kg-1 in 88 patients undergoing TKA with preoperative pain catastrophising score >20 or regular opioid use was designed. The primary outcome was the proportion of patients experiencing moderate-to-severe pain (VAS >30) during a 5 m walk 24 h postoperatively. Secondary outcomes included pain at rest during nights and at passive leg raise, C-reactive protein, opioid use, quality of sleep, Quality of Recovery-15 and Opioid-Related Symptom Distress Scale, readmission, and complications. RESULTS: Moderate-to-severe pain when walking 24 h postoperatively was reduced (high dose vs intermediate dose, 49% vs 79%; P<0.01), along with pain at leg raise at 24 and 48 h (14% vs 29%, P=0.02 and 12% vs 31%, P=0.03, respectively). C-reactive protein was reduced in the high-dose group at both 24 and 48 h (both P<0.01). Quality of Recovery-15 was also improved (P<0.01). CONCLUSIONS: When compared with preoperative dexamethasone 0.3 mg kg-1 i.v., dexamethasone 1 mg kg-1 reduced moderate-to-severe pain 24 h after TKA and improved recovery in high pain responders without apparent side-effects. CLINICAL TRIAL REGISTRATION: NCT03763734.

Rare and Atypical Presentations of Acute Disseminated Encephalomyelitis in Children: A Case Series.

Acute disseminated encephalomyelitis (ADEM) is a monophasic demyelinating disorder of central nervous system occurring in children with a wide range of clinical manifestations after infection or vaccination. There are few case reports in literature, describing atypical presentations of ADEM with fever of unknown origin, autonomic dysfunction, complex movement disorders such as myoclonus, dystonia and chorea, acute psychosis and myocarditis. Here, we report four cases of ADEM with atypical features like uniocular blindness, myelin oligodendrocyte glycoprotein antibodies negative multiphasic disseminated encephalomyelitis, ADEM mimicking Guillain-Barre syndrome at presentation and isolated spinal ADEM. Treatment with high-dose steroids elicited an excellent neurological outcome in all patients. A high index of clinical suspicion along-with awareness of atypical features, magnetic resonance imaging and cerebrospinal fluid studies are of paramount importance in establishing ADEM diagnosis and initiation of early treatment for better outcome.

Veno-occlusive disease of the liver in the absence of elevation in bilirubin in pediatric patients after hematopoietic stem cell transplantation.

Veno-occlusive disease (VOD) of the liver is a well-described and significant complication of hematopoietic stem cell transplantation (HSCT), with limited successful therapeutic options in severe cases. Prompt diagnosis and initiation of treatment is crucial to restrict the extent of disease. However, a subset of patients may not meet all current diagnostic criteria at presentation, and waiting for these to be met may delay therapy. We retrospectively reviewed 794 HSCT patients treated at our institution between 2003 and 2013, identifying 17 (2.1%) who developed VOD. Of these, 5 (29%) were noted to have an absence of elevated bilirubin at the time of VOD diagnosis and reversal of portal venous flow on ultrasound. Median total and conjugated bilirubin at VOD diagnosis were 1.0 and 0.2 mg/dL, respectively. All 5 patients were subsequently diagnosed with multiorgan failure associated with VOD, including 1 with encephalopathy. Four were treated with intravenous high-dose methylprednisolone (500 mg/m(2) per dose every 12 hours for 6 doses). One patient received defibrotide therapy in addition to steroids and another supportive care alone. VOD resolved in 4 of 5 patients, with median time to resolution of VOD, defined as recovery of all organ function and normalization of bilirubin and portal venous flow, of 8 days. Two patients died later from progressive primary disease and chronic graft-versus-host disease, respectively. We conclude that a high index of suspicion for VOD should be maintained in patients despite lack of bilirubin elevation in the presence of other diagnostic criteria such as hepatomegaly, abdominal pain, ascites, or weight gain. Early ultrasound evaluation in these patients may lead to more timely diagnosis and therapeutic interventions.

Case report: Autoimmune encephalomyelitis following cytomegalovirus infection after allogeneic hematopoietic stem cell transplantation.

Introduction: Cytomegalovirus (CMV) can cause various end-organ diseases in immunocompromised hosts, including allogeneic hematopoietic cell transplant (allo-HSCT) recipients. Interestingly, CMV viremia has been associated with various complications and poor prognosis in allo-HSCT recipients. Complications involving the central nervous system (CNS) occur in 9-14% of patients following allo-HSCT. However, autoimmune encephalitis (AE) secondary to CMV infection after allo-HSCT has rarely been reported. Here we report a case of possible AE following CMV viremia after allo-HSCT, which was successfully treated with high-dose pulsed methylprednisolone and intravenous immunoglobulins (IVIg). Case description: A 53-year-old female underwent allo-HSCT for T-lymphoblastic lymphoma/leukemia. The patient developed CMV viremia on day 36 after transplantation, and serum CMV-DNA remained positive after initiating ganciclovir antiviral therapy, turning negative one month later. Four months later, she started experiencing memory impairment, weakness in the left limbs, cognitive dysfunction, and hallucinations. A magnetic resonance imaging brain scan showed scattered ischemic lesions under the bilateral frontal cortex. Viral detection in cerebral spinal fluid (CSF) by next-generation gene sequencing technology showed no obvious abnormality. Antibodies specific to AE and paraneoplastic diseases in serum and CSF were absent. The oligoclonal bands in the CSF were detected using isoelectric focusing and immunofixation, and the results were negative. However, after extensive investigation regarding infections, autoimmune disorders, and recurrence of the malignancy, possible AE could not be excluded. The patient was treated with high-dose steroids combined with IVIg therapy; the patient's symptoms were significantly improved. Conclusion: The mechanisms of AE after allo-HSCT and the relationship with CMV infection should be further studied. Therefore, reporting this and similar cases will improve our awareness and understanding of the underlying disease mechanisms.

Long-term follow up of the combination of ofatumumab, high-dose methylprednisolone, and lenalidomide for untreated chronic lymphocytic leukemia with biomarker analysis.

BACKGROUND: Advancements in frontline therapy and chemotherapy-sparing treatments in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) have altered the treatment algorithms of this disease. We present a frontline alternative for treatment- naïve (TN) CLL/SLL patients. METHODS: This was a single-center, phase 2 study of high-dose methylprednisolone (HDMP) and ofatumumab with lenalidomide and ofatumumab consolidative therapy for all comers with TN CLL/SLL. Treatment was continued until disease progression or intolerable side effects. Patients were assessed for response per iwCLL 2008 criteria after completing cycles 3 and 12. RESULTS: Forty-five patients were enrolled (median age, 62.6 years). High-risk features included del17p (18%), Del11q (22%), and unmutated IGHV gene (76%). Median treatment duration was 32·2 (2·7-75·9) months. Thirty-six patients discontinued treatment due to disease progression (22%), adverse events (40%), allogeneic hematopoietic cell transplantation (allo-HCT) (7%), consent withdrawal (4%), and secondary malignancies (7%). The best overall and complete response rates were 96& and 29% respectively. At median follow-up of 61·7 (5·6-84·9) months, 9 patients remained on treatment. Median progression-free survival was 54·4 (2·9-77·6) months. Three patients underwent allo-HCT after a median of 3 (3-4) treatment cycles. Treatment was well tolerated, with a grade 3/4 infusion reaction in one patient. The most common grade 3/4 hematological adverse event was neutropenia (69%). Four patients had grade 3/4 infections. No grade 3/4 tumor flares, tumor lysis syndrome, or thrombosis were observed. CONCLUSION: The combination of ofatumumab, HDMP, and lenalidomide was effective and relatively well tolerated in treatment-naive CLL/SLL. Its role in the frontline setting remains unclear given the current available and effective treatment options. FUNDING: The funders had no role in the study.

Neurosarcoidosis: A Rare Presentation as a Seizure.

Neurosarcoidosis is a rare disorder that can develop in patients with a history of sarcoidosis or can develop even when sarcoidosis is not diagnosed. It is a granulomatous disease of the nervous system that causes different neurological disorders based on its location. However, diagnosing neurosarcoidosis remains a challenge as it mimics many other neurological disorders and does not have any biochemical markers of high specificity. A tissue-proven biopsy is the gold standard but is difficult to obtain in neurological illnesses. Thus, diagnosis is established based on the clinical syndrome and imaging, which mostly show meningeal/parenchymal lesion enhancement, in addition to the exclusion of other causes. Glucocorticoids, immunosuppressants, and anti-tumour necrosis factor (TNF) drugs are the mainstays of treatment. We discuss a case of neurosarcoidosis in a 52-year-old woman with a known history of sarcoidosis.

Neuro-Behçet's disease with atypical subcortical nodular lesions: A case report and treatment approach.

Neuro-Behçet's disease (NB) is a rare complication of Behçet's disease (BD) characterised by central nervous system involvement. While NB typically presents with brainstem lesions, we report an unusual case of NB in a 27-year-old male with multiple subcortical nodular brain lesions but without brainstem, thalamic, or basal ganglia involvement, making this presentation exceptionally rare. The patient had a prior diagnosis of BD and was HLA-B51 positive. He presented with a sudden loss of consciousness, which was attributed to a seizure. Imaging studies showed low-density areas in the white matter of the bilateral temporal lobes and the right frontoparietal lobe on brain CT. Cerebrospinal fluid examination indicated elevated initial pressure and protein concentration, along with increased interleukin-6. Despite presenting with nodular brain lesions, distinguishing between NB and infectious diseases such as tuberculosis (TB) was challenging, and required brain biopsy revealing vasculitis. However, even with this biopsy result, TB could not be ruled out, so TB was treated at the same time. Treatment with anti-TB drugs and standard steroid therapy initially failed to improve the patient's condition. However, increasing the steroid dosage considering the increased steroid degradation by rifampicin, including pulse therapy with 2 g of methylprednisolone, followed by 18 mg of betamethasone, led to remission of the nodular brain lesions and resolution of the nasopharyngeal ulcer. This case highlights the diagnostic challenge of differentiating between NB and TB based on imaging alone and the potential efficacy of high-dose steroid therapy in cases of steroid-resistant NB with subcortical nodular brain lesions.

Neurosarcoidosis Presenting With Confusion and Speech Alteration.

Neurosarcoidosis (NS) is a rare manifestation of sarcoidosis, a multisystem inflammatory granulomatous disease. We describe a unique case of NS with confusion and speech alteration as presenting symptoms. A 65-year-old male with a history of Ramsay Hunt syndrome and Lyme infection presented to the emergency room after an acute episode of disorientation, garbled speech, and left facial droop, along with months of worsening generalized fatigue, gait ataxia, left-sided periorbital headaches, bilateral peripheral neuropathy, and bladder disturbance. A recent CT scan of his chest showed mediastinal lymphadenopathy, and a lymph node biopsy revealed non-necrotizing granulomas, Langhans giant cells, and focal Schaumann bodies. A brain MRI revealed a mildly enlarged anterior pituitary gland, mild prominent enhancement of the trigeminal nerves bilaterally, and right frontal, parietal, and superior temporal leptomeningeal enhancement. Lumbar puncture cerebrospinal fluid analyses were consistent with aseptic meningitis. A diagnosis of probable NS was made. The patient received IV methylprednisolone 1 g for three days, followed by a prednisone taper with clinical improvement. NS is a diagnostic challenge due to the variability of clinical presentations of the disease. This case demonstrates how vague chronic neurologic symptoms preceding an unusual acute clinical presentation delayed the diagnosis of NS in a patient with sarcoidosis.

Severe polymyositis occurring in a cancer patient directly after chemotherapy: etiology and management.

A 72-year-old woman was diagnosed with metastatic colorectal cancer and treated with oxaliplatin-based chemotherapy and bevacizumab. One week after the second administration of chemotherapy, she presented acute-onset dysphagia and rapidly progressing proximal muscle weakness, associated with elevation of the creatinine phosphokinase enzymes. Magnetic resonance imaging raised suspicion of polymyositis. Etiology remained unclear but paraneoplastic origin or immune modulation by chemotherapy was considered. High-dose methylprednisolone and intravenous immunoglobulins were started with continuation of chemotherapy. Although there was rapid normalization of muscle enzyme, the general status deteriorated rapidly with aggravation of dysphagia, complete immobilization and death. This case highlights the importance of considering muscle weakness as paraneoplastic syndrome or drug-induced toxicity in colorectal cancer patients. Despite aggressive management, prognosis remains poor.

Predictive Factors of Resistance to High-Dose Steroids Therapy in Acute Attacks of Neuromyelitis Optica Spectrum Disorder.

High-dose steroids, the first-line therapy for acute attacks in neuromyelitis optica spectrum disorder (NMOSD), were ineffective in a proportion of NMOSD attacks. This study aimed to explore possible predictors of high-dose steroid resistance. Demographics and disease characteristics of acute attacks were compared between those who responded to high-dose intravenous methylprednisolone (IVMP) and those resistant to IVMP. In total, 197 attacks in 160 patients were identified in our NMOSD registry. Compared with responders, attacks resistant to high-dose steroids tended to have a higher proportion of previous history of immunosuppressive use (25.5 vs. 15.5%, p = 0.080). Significantly higher levels of proteins in the cerebrospinal fluid (CSF) were found in non-responders than in responders [485.5 (388-656) vs. 387 (291.5-532) mg/L, p = 0.006]. More active lesions were found in the brain stem of non-responders (8 attacks in 55, 14.5%), especially in the pons (7.3%) and medulla (14.5%), as opposed to responders (7 patients in 142, 4.9%). Multivariable logistic regression showed that resistance to high-dose steroid treatment was associated with previous immunosuppressant use [odds ratio (OR), 2.31; 95% confidence interval (CI) 1.002-5.34, p = 0.049], CSF protein level above 450 mg/L (OR 3.42, 95% CI 1.72-6.82, p < 0.001), and active lesions in the brainstem (OR 3.80, 95% CI 1.17-12.32, p = 0.026). In conclusion, NMOSD patients with previous use of immunosuppressants, higher levels of CSF protein, and active lesions in the brainstem are more likely to respond poorly to high-dose IVMP alone during an acute attack.

Interstitial Lung Disease Associated Acute Respiratory Failure Requiring Invasive Mechanical Ventilation: A Retrospective Analysis.

BACKGROUND: Interstitial Lung Disease [ILD] patients requiring Invasive Mechanical Ventilation [IMV] for Acute Respiratory Failure [ARF] are known to have a poor prognosis. Few studies have investigated determinants of outcomes and the utility of trialing Non-Invasive Positive Pressure Ventilation [NIPPV] prior to IMV to see if there are any effect[s] on mortality or morbidity. METHODS: A retrospective study was designed using patients at four different intensive care units within one health care system. The primary objective was to determine if there are differences in outcomes for in-hospital and one-year mortality between patients who undergo NIPPV prior to IMV and those who receive only IMV. A secondary objective was to identify potential determinants of outcomes. RESULTS: Out of 54 ILD patients with ARF treated with IMV, 20 (37.0%) survived until hospital discharge and 10 (18.5%) were alive at one-year. There was no significant mortality difference between patients trialed on NIPPV prior to IMV and those receiving only IMV. Several key determinants of outcomes were identified with higher mortality, including higher ventilatory support, idiopathic pulmonary fibrosis (IPF) subtype, high dose steroids, use of vasopressors, supraventricular tachycardias (SVTs), and higher body mass index. CONCLUSION: Considering that patients trialed on NIPPV prior to IMV were associated with no mortality disadvantage to patients treated with only IMV, trialing patients on NIPPV may identify responders and avoid complications associated with IMV. Increased ventilator support, need of vasopressors, SVTs, and high dose steroids reflect higher mortality and palliative care involvement should be considered as early as possible if a lung transplant is not an option.

Short Course of High-dose Steroids for Anaphylaxis Caused Flare Up of Tuberculosis: A Case Report.

A 25-year-old male patient received high-dose intravenous steroids for life-threatening anaphylaxis because of bee sting only for 4 days resulted in reactivation of latent tuberculosis infection (LTBI). Clinical presentation is acute form of progressive pulmonary tuberculosis with pleural efusion that can be misdiagnosed as a community-acquired pneumonia. High index of suspicion with adequate evaluation is must in all cases to have satisfactory treatment outcome. Bronchoscopy is crucial in evaluation with histopathology expertise is must while managing such cases.

Atrial fibrillation following therapy with high-dose i.v. methylprednisolone: A brief case-based review.

Atrial fibrillation following high-dose i.v. steroids for treatment of severe immune-mediated diseases has been rarely reported in the literature. Here we report a further case of atrial fibrillation following high-dose i.v. methylprednisolone (HDIVMP) therapy of severe thrombocytopenia in a female patient with a flare-up of systemic lupus erythematosus (SLE). The available literature on this topic is reviewed as well.

A Case of Tolosa-Hunt Syndrome Presented with Headache, Ptosis and Vision Loss

Cavernous sinus syndrome (CSS) is defined as the involvement of two or more of the third, fourth, fifth (V1, V2) or sixth cranial nerves or involvement of only one of them in combination with a neuroimaging-confirmed lesion in the cavernous sinus. Some cases of CSS are attributed to Tolosa-Hunt syndrome (THS), an idiopathic inflammatory disease of the cavernous sinus. THS is characterized by painful ophthalmoplegia due to granulomatous inflammation in the cavernous sinus. THS is a diagnosis of exclusion that requires a vigorous series of differential diagnoses, and corticosteroid therapy is known to dramatically resolve clinical findings of THS. We report a case of a patient with painful ophthalmoplegia associated with vision loss, which was suspected to be THS. This patient followed a relatively typical clinical course of THS on steroid pulse therapy. We emphasize the differential diagnosis of THS, its presentation, and treatment.

Idiopathic Retroperitoneal Fibrosis Treated with High Dose Steroids / 대한신장학회잡지

Idiopathic retroperitoneal fibrosis is proliferation of fibrous tissue with inflammatory process due to unknown etiology, that may involve the ureters and other retroperitoneal structures. The majority of reported cases have been treated surgically by ureterolysis or intraperitonealization of the ureters. Recently, successful management of retroperitoneal fibrosis by administration of steroids also has been reported. We report two cases of patients who underwent successful treatment of an idiopathic retroperitoneal fibrosis with high dose steroids therapy.
