RESUMO

An 83-year-old man with hepatocellular carcinoma developed muscle weakness, ptosis, and dyspnea 3 weeks after receiving atezolizumab. Soon after, mechanical ventilation was initiated, which was followed by marked blood pressure spikes. The levels of creatine kinase and troponin-I were significantly elevated, and acetylcholine receptor antibodies were positive. The patient was diagnosed with immune checkpoint inhibitor (ICI)-induced myositis, myasthenia gravis (MG), myocarditis, and suspected autoimmune autonomic ganglionopathy (AAG). After immunotherapy, the serum markers and blood pressure normalized, and he was weaned from the ventilator after five months. To our knowledge, this is the first reported case of AAG secondary to ICI-induced myositis, MG, and myocarditis.

RESUMO

A 47-year-old woman was admitted to our hospital for scrutiny of limb weakness and orthostatic hypotension that had progressed from childhood. She had been treated for alacrima and esophageal achalasia from childhood. On admission, she had hyperreflexia of upper and lower extremities, distal predominant muscle atrophy in the lower extremities, decreased sensation of the distal extremities, and autonomic neuropathy. Her blood test results ruled out adrenal insufficiency, but Schirmer's test was positive. Given the lacrimation symptoms, esophageal achalasia, and neuropathy, the patient was diagnosed with triple A syndrome in whom a c.463C>T mutation (p.R155C) was found in the AAAS gene by genetic testing. Triple A syndrome is an autosomal recessive inherited disease caused by mutations in the AAAS gene. Genetic testing of the AAAS gene should be considered in patients with one or two of main symptoms of triple A syndrome.

RESUMO

Previous studies have reported that transcranial direct current stimulation (tDCS) of the frontal polar area (FPA) ameliorated motor disability in patients with Parkinson's disease (PD). Here we report changes in neuromelanin (NM) imaging of dopaminergic neurons before and after rehabilitation combined with anodal tDCS over the FPA for 2 weeks in a PD patient. After the intervention, the patient showed clinically meaningful improvements while the NM-sensitive area in the SN increased by 18.8%. This case study is the first report of NM imaging of the SN in a PD patient who received tDCS.Abbreviations FPA: front polar area; PD: Parkinson's disease; NM: neuromelanin; DCI: DOPA decarboxylase inhibitor; STEF: simple test for evaluating hand function; TUG: timed up and go test; TMT: trail-making test; SN: substantia nigra; NM-MRI: neuromelanin magnetic resonance imaging; MCID: the minimal clinically important difference; SNpc: substantia nigra pars compacta; VTA: ventral tegmental area; LC: locus coeruleus; PFC: prefrontal cortex; M1: primary motor cortex; MDS: Movement Disorder Society; MIBG: 123I-metaiodobenzylguanidine; SBR: specific binding ratio; SPECT: single-photon emission computed tomography; DAT: dopamine transporter; NIBS: noninvasive brain stimulation; tDCS: transcranial direct current stimulation; MAOB: monoamine oxidase B; DCI: decarboxylase inhibitor; repetitive transcranial magnetic stimulation: rTMS; diffusion tensor imaging: DTI; arterial spin labeling: ASL.

RESUMO

BACKGROUND: Extracellular adenosine 5'-triphosphate (ATP) has been suggested to cause neuroinflammation and motor neuron degeneration by activating microglia and astrocytes in amyotrophic lateral sclerosis (ALS). Since we have developed a highly sensitive ATP assay system, we examined cerebrospinal fluid (CSF) ATP levels in patients with ALS whether it can be a useful biomarker in ALS. METHODS: Forty-eight CSF samples from 44 patients with ALS were assayed for ATP with a newly established, highly sensitive assay system using luciferase luminous reaction. CSF samples from patients with idiopathic normal pressure hydrocephalus (iNPH) were assayed as a control. Patients were divided into two groups depending on their disease severity, as evaluated using the Medical Research Council (MRC) sum score. Correlations between the CSF ATP levels and other factors, including clinical data and serum creatinine levels, were evaluated. RESULTS: CSF ATP levels were significantly higher in patients with ALS than in the iNPH (716 ± 411 vs. 3635 ± 5465 pmol/L, p < 0.01). CSF ATP levels were significantly higher in the more severe group than in the iNPH group (6860 ± 8312 vs. 716 ± 411 pmol/L, p < 0.05) and mild group (6860 ± 8312 vs. 2676 ± 3959 pmol/L, p < 0.05) respectively. ALS functional rating scale-revised (ALSFRS-R) (37.9 ± 5.7 vs. 42.4 ± 2.8, p < 0.01) and serum creatinine levels (0.51 ± 0.13 vs. 0.68 ± 0.23 mg/dL, p < 0.05) were significantly lower in the severe group than in the mild group respectively. A negative correlation of CSF ATP levels with MRC sum score was demonstrated in the correlation analysis adjusted for age and sex (r = -0.3, p = 0.08). CONCLUSIONS: Extracellular ATP is particularly increased in the CSF of patients with advanced ALS. CSF ATP levels may be a useful biomarker for evaluating disease severity in patients with ALS.

RESUMO

OBJECTIVES: Neurofilament light chain (NfL) levels have been suggested as reflecting axonal damage in various inflammatory and neurodegenerative disorders, including acquired peripheral neuropathies. We aimed to investigate if serum NfL (sNfL) levels can be a biomarker of disease activity and treatment response in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). MATERIALS AND METHODS: The sNfL levels of eleven newly diagnosed patients with CIDP were retrospectively assayed and compared with seven healthy volunteers. The levels were assayed before and after intravenous immunoglobulin treatment in patients with CIDP and were also assayed in the remission period. RESULTS: Baseline sNfL levels in patients with CIDP before treatment were significantly higher than those in healthy controls. The levels significantly decreased overtime after one month of treatment and in remission period. There were significant negative correlations between the sNfL levels and the disease duration (the interval between the onset of the disease and the time of sampling), and weak correlations between the sNfL levels and overall neuropathy limitations scale. CONCLUSIONS: sNfL may be a potential biomarker reflecting the disease activity in patients with CIDP.

RESUMO

This study aimed to evaluate genotype-phenotype correlations of Parkinson's disease (PD) patients with phospholipase A2 group V (PLA2G6) variants. We analyzed the DNA of 798 patients with PD, including 78 PD patients reported previously, and 336 in-house controls. We screened the exons and exon-intron boundaries of PLA2G6 using the Ion Torrent system and Sanger method. We identified 21 patients with 18 rare variants, such that 1, 9, and 11 patients were homozygous, heterozygous, and compound heterozygous, respectively, with respect to PLA2G6 variants. The allele frequency was approximately equal between patients with familial PD and those with sporadic PD. The PLA2G6 variants detected frequently were identified in the early-onset sporadic PD group. Patients who were homozygous for a variant showed more severe symptoms than those who were heterozygous for the variant. The most common variant was p.R635Q in our cohort, which was considered a risk variant for PD. Thus, the variants of PLA2G6 may play a role in familial PD and early-onset sporadic PD.

RESUMO

PURPOSE: The purpose of this study is to increase awareness of the importance of considering neuromyelitis optica spectrum disorder (NMOSD) as a differential diagnosis for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). METHODS: We report two NMOSD patients demonstrating magnetic resonance imaging (MRI) abnormalities resembling those of CADASIL. RESULTS: Brain MRIs of both patients showed symmetrical hyperintense signals in the temporal poles and cerebral hemispheres on T2 weighted images. One case also involved the bilateral external capsule. The chief complaint of both patients was loss of visual acuity, and neurologic examination showed no other apparent neurological signs or symptoms. Anti-aquaporin-4 antibodies were detected on serological examination, and NMOSD was subsequently diagnosed. Visual acuity improved following intravenous methylprednisolone therapy. One patient refused further immunological treatment. Although she remained clinically stable, gradual radiographic deterioration was observed. This deterioration then stabilized after the patient commenced oral prednisolone therapy. The other patient was treated with prednisolone and azathioprine. She is clinically stable, but we have observed gradual radiographic deterioration over the past 5 years. CONCLUSION: MRI findings in patients with NMOSD may resemble those of CADASIL, namely symmetrical hyperintensities in the temporal poles, external capsules and cerebral hemispheres. NMOSD is a differential diagnosis for CADASIL, and testing for anti-AQP4 antibodies should be considered.

RESUMO

A 17-year-old woman was admitted to our hospital because of a high fever, consciousness disturbance, and delirious behavior. Methicillin susceptible Staphylococcus aureus (MSSA) infection was confirmed by blood culture. Transthoracic echocardiogram showed no abnormality at first. Diffusion-weighted brain MRI showed a high intensity lesion in the middle portion of the splenium, which was shown as low intensity on apparent diffusion coefficient map. Then, antibiotics therapy was started against suspected bacterial meningitis, while the lumbar puncture was not performed because of the decreased number of platelets. Since the systolic murmur appeared at the apex on day 12, the diagnosis with infectious endocarditis was made by transthoracic echocardiogram. The MRI abnormalities disappeared on day 16 and we diagnosed her with clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) associated with infectious endocarditis. This case suggests that MERS can occur associated with infectious endocarditis caused by Staphylococcus aureus.

RESUMO

Parkinson's disease (PD) is a neurodegenerative disorder with motor and non-motor symptoms due to degeneration of dopaminergic neurons. The current pharmacological treatments induce complications associated with long-term use. However, current stimulation techniques for PD treatment, such as deep brain stimulation (DBS), are too invasive. In this context, non-invasive brain stimulation including transcranial direct current stimulation (tDCS) may be a safe and effective alternative treatment for PD. We previously reported that anodal tDCS over the frontal polar area (FPA) improved motor functions in heathy subjects. Therefore, in the present study, effects of tDCS over the FPA on motor and cognitive functions of PD patients were analyzed. Nine PD patients (3 men and 6 women) participated in this cross over study with three tDCS protocols; anodal, cathodal or sham tDCS over the FPA. Each tDCS protocol was applied for 1 week (5 times/week). Before and after each protocol, motor and cognitive functions of the patients were assessed using Unified PD Rating Scale [UPDRS (part III: motor examination)], Fugl Meyer Assessment set (FMA), Simple Test for Evaluating hand Function (STEF) and Trail Making Test A (TMT-A). The results indicated that anodal stimulation significantly decreased scores of motor disability in UPDRS-III compared with sham and cathodal stimulation, and significantly increased scores of motor functions in FMA compared with sham stimulation. Furthermore, anodal stimulation significantly decreased time to complete a motor task requiring high dexterity in STEF compared with those requiring low and medium levels of dexterity. In addition, anodal stimulation significantly decreased time to complete the TMT-A task, which requires executive functions, compared with sham stimulation. To the best of our knowledge, this is the first clinical research reporting that tDCS over the FPA successfully improved the motor and non-motor functions in PD patients. These findings suggest that tDCS over the FPA might be a useful alternative for the treatment of PD patients.

RESUMO

A 63-year-old man developed a syndrome of cauda equine, with the numbness which is a left lower extremity from the left buttocks, weakness of left leg, and a dysfunction of bladder and bowel. Enhanced MRI revealed the enhancement of lower cauda equine, and a nerve conduction test revealed decreased F-wave persistency in the tibial nerve and increased F-wave latency in the peroneal nerve on the both sides. M-proteinemia was admitted and myeloma was suspected. By a biopsy of a vertebral arch, we diagnosed with diffuse large B-cell lymphoma. We treated with dexamethasone and R-CHOP (rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, prednisone (prednisolone)), then the symptom was improved. In case of caude equine syndrome with M-proteinemia, a possibility of the malignant lymphoma should also be considered.

RESUMO

BACKGROUND: Although smoking is a risk factor for cardiovascular diseases, little is known about the impact of smoking on long-term outcomes in patients with atrial fibrillation (AF). METHODS: In 426 consecutive patients with nonvalvular AF (mean age, 66 years; 307 men; mean follow-up, 5.8±3.2 years), clinical variables including smoking status, CHADS2, and CHA2DS2-VASc score, incidences of cardiovascular events (stroke, myocardial infarction, or admission for heart failure), bleeding, and mortality were determined. RESULTS: Incidences of intracranial bleeding (0.7% vs 0.1%/year, p<0.01), all-cause mortality (4.9% vs 2.6%/year, p<0.01), and death from stroke (0.8% vs 0.2%/year, p<0.05) were higher in patients with history of smoking than in those without it. Incidence of intracranial bleeding was significantly higher in persistent smokers than in non-persistent smokers (1.2% vs 0.2%/year, p<0.01). History of smoking predicted all-cause mortality [hazard ratio (HR), 2.7; 95% confidence interval (CI), 1.7-4.5; p<0.01] and death from stroke (HR 4.7; 95% CI 1.0-22.3; p<0.05) independent of age, antithrombotic treatment, CHADS2, and CHA2DS2-VASc score. Persistent smoking predicted intracranial bleeding (HR 4.4; 95% CI 1.1-17.6; p<0.05) independent of age and antithrombotic treatment. CONCLUSIONS: Smoking status, independent of age, antithrombotic treatment, and clinical risk factors, predicted long-term adverse outcomes including bleeding events in patients with nonvalvular AF. There might be an obvious impact of persistent smoking on intracranial bleeding.

RESUMO

A 76-year-old man was admitted to our hospital presenting with fever, redness and pain in both the periocular regions, and disturbance of consciousness. He had neck stiffness, and cerebrospinal fluid analysis suggested aseptic meningoencephalitis. Laboratory tests showed increased levels of C-reactive protein, soluble IL-2 receptor (sIL-2R) and MPO-ANCA. Magnetic resonance imaging revealed hyperplastic bone marrow in the clivus and cervical vertebra. Although T-cell receptor gene rearrangement was detected in the bone marrow blood, bone marrow biopsy of the ilium showed no malignant findings. Then he experienced bilateral auricular inflammation and painful erythema of the ankle. A leg skin biopsy demonstrated neutrophilic infiltration into the dermis with no signs of vasculitis. His HLA-type was defined as Cw1. He was subsequently diagnosed with neuro-Sweet disease. Intravenous administration of methylprednisolone (1,000 mg/day) for 5 days and subsequent oral intake of prednisolone (60 mg/day) improved his symptoms. When the prednisolone dose was reduced to 30 mg/day, his symptoms returned and a new lesion was detected in the splenium of the corpus callosum. Upon additional treatment with cyclosporine, the prednisolone dose could be reduced without symptom relapse; sIL-2R and MPO-ANCA levels also decreased to normal. The present case suggested that the activity of neuro-Sweet disease may be associated with myeloid hyperplasia, T-cell receptor gene rearrangement and the amounts of soluble interleukin-2 receptor and MPO-ANCA.

RESUMO

It is still unclear whether deep brain stimulation targeted to the bilateral subthalamic nucleus (STN-DBS) affects cognitive function in Parkinson's disease (PD). This prospective study was aimed to systemically evaluate the impact of bilateral STN-DBS on motor and cognitive functions in patients with PD. This study included totally 11 Japanese patients with medically intolerant PD. Neurological and cognitive status was precisely evaluated before and 1 year after bilateral STN-DBS, using unified Parkinson's disease rating scale (UPDRS), levodopa equivalent doses, mini-mental state examination (MMSE), Japanese adult reading test (JART), repeatable battery for the assessment of neuropsychological status (RBANS), and Wechsler adult intelligence scale-revised (WAIS-R). Preoperative RBANS and WAIS-R identified cognitive dysfunction that could not be detected by MMSE and JART. Before surgery, PD patients had significantly impaired immediate memory and attention. Motor function significantly improved 1 year after bilateral STN-DBS. Bilateral STN-DBS did not affect any score on cognitive examinations. However, postoperative improvements of total score on RBANS and performance intelligence quotient (PIQ) scores on WAIS-R were closely related to those of UPDRS part III off (R(2) = 0.61, P < 0.01; R(2) = 0.39, P < 0.05, respectively). These findings strongly suggest that bilateral STN-DBS may significantly improve cognitive function in a certain subgroup of patients whose therapeutic effects on motor function are prominent.

RESUMO

BACKGROUND AND PURPOSE: Not only clinical factors, including the CHADS(2) score, but also echocardiographic findings have been reported to be useful for predicting the risk of ischemic stroke in patients with nonvalvular atrial fibrillation (NVAF). However, it remains to be determined which of these factors might be more relevant for evaluation of the risk of stroke in each patient. METHODS: In 490 patients with NVAF who underwent transesophageal echocardiography (TEE), we examined the long-term incidence of ischemic stroke events (mean follow-up time, 5.7±3.3 years). For each patient, the predictive values of gender, the CHADS(2) risk factors (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, history of cerebral ischemia), the CHADS(2) score, and the findings on echocardiography, including TEE risk markers, were assessed. RESULTS: The ischemic stroke rate was significantly correlated with the CHADS(2) score (p<0.05). According to the results of univariate analyses, age ≥75 years, history of cerebral ischemia, CHADS(2) score ≥2, and presence of TEE risk were significantly correlated with the incidence of ischemic stroke. Cox proportional hazards regression analyses identified age ≥75 years and presence of TEE risk as significant predictors of subsequent ischemic stroke events in patients with NVAF. As compared with that in persons below 75 years of age without TEE risk, the ischemic stroke rate was significantly higher in persons who were ≥75 years of age with TEE risk (4.3 vs. 0.56%/year, adjusted hazard ratio=8.94, p<0.001). CONCLUSIONS: TEE findings might be more relevant predictors of ischemic stroke than the CHADS(2) score in patients with NVAF. The stroke risk was more than 8-fold higher in patients aged ≥75 years with TEE risk.

RESUMO

BACKGROUND: We studied the usefulness of hemostatic biomarkers in assessing the pathology of thrombus formation, subtype diagnosis, prognosis in the acute phase of cerebral infarction, and differences between various hemostatic biomarkers. METHODS: Our study included 69 patients with acute cerebral infarction who had been hospitalized within 2 days of stroke onset. Fibrin monomer complex (FMC), soluble fibrin (SF), D-dimer, thrombin-antithrombin III complex, fibrinogen, antithrombin III, and fibrin/fibrinogen degradation products (FDPs) were assayed as hemostatic biomarkers on days 1, 2, 3, and 7 of hospitalization. RESULTS: In the cardioembolic (CE) stroke group, FMC and SF levels were significantly higher on days 1 and 2 of hospitalization, and D-dimer levels were significantly higher on day 1 of hospitalization, compared to the noncardioembolic (non-CE) stroke group. FDP levels were significantly higher at all times in the CE group compared to the non-CE group. Neither the National Institute of Health Stroke Scale (NIHSS) used during hospitalization nor the modified Rankin Scale (mRS) used at discharge found any significant correlations to hemostatic biomarkers, but the NIHSS score during hospitalization was significantly higher in the CE group than in the non-CE group. CONCLUSIONS: Measurements of hemostatic biomarkers, such as FMC, SF, and D-dimer on the early stage of cerebral infarction are useful for distinguishing between CE and non-CE stroke.

RESUMO

BACKGROUND: Few multiple case studies of the effects of deep brain stimulation for camptocormia associated with Parkinson's disease have been reported. Although deep brain stimulation was in some cases not effective against camptocormia, it is unclear in which types of patients it was effective in treating camptocormia. OBJECTIVE: We treated 4 Parkinson's disease patients with camptocormia and evaluated their paraspinal muscle status by computed tomography to specify the characteristics of cases of effective treatment. METHODS: The 2 female and 2 male patients in this study were 60-69 years old, with a disease duration from onset to surgery of 7-13 years and a follow-up period of 18-40 months. The electrodes were implanted bilaterally in the subthalamic nuclei. RESULTS: Camptocormia was improved in 3 cases, and was unchanged in the remaining case although other parkinsonian symptoms improved. The computed tomography number of paraspinal muscle in the unimproved patient was much smaller than that in the improved patients. CONCLUSIONS: A relationship may exist between improvement of camptocormia and severity of paraspinal muscle degeneration.

RESUMO

Chronic kidney disease is a risk factor for cardiovascular events, but how it relates to the prognosis associated with clinical risk factors for thromboembolism in patients with nonvalvular atrial fibrillation (AF) is not well known. Estimated glomerular filtration rate (eGFR), score for congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, and stroke/transient ischemic attack (CHADS(2)), and clinical outcomes of cardiovascular events were determined in 387 patients with nonvalvular AF (mean age 66 years, 289 men, mean follow-up 5.6 ± 3.2 years). Decreased eGFR (<60 ml/min/1.73 m(2)) combined with CHADS(2) score ≥2 was associated with higher all-cause (12.9% vs 1.4% per year, hazard ratio [HR] 6.9, p <0.001) and cardiovascular (6.5% vs 0.2% per year, HR 29.7, p <0.001) mortalities compared to preserved eGFR (≥60 ml/min/1.73 m(2)) combined with CHADS(2) score <2. This was also true for rates of cardiac events (cardiac death, nonfatal myocardial infarction, or hospitalization for worsening of heart failure, 10.4% vs 1.3% per year, HR 8.9, p <0.001), ischemic stroke (3.6% vs 0.2% per year, HR 11.0, p <0.001), and cardiovascular events (cardiac events and ischemic stroke, 13.6% vs 1.5% per year, HR 8.3, p <0.001). On multivariate analysis, CHADS(2) score ≥2, decreased eGFR, and male gender independently predicted all-cause mortality. In conclusion, combined eGFR and CHADS(2) score could be an independent powerful predictor of cardiovascular events and mortality in patients with nonvalvular AF. Long-term mortality, cardiac events, and stroke risk were >8 times higher when decreased eGFR (<60 ml/min/1.73 m(2)) was present with higher CHADS(2) score (≥2).

RESUMO

BACKGROUND AND PURPOSE: Plasma D-dimer levels are elevated during the acute phase of cerebral infarction (CI). We investigated whether the D-dimer level on admission and other clinical characteristics could be used to predict the poor outcome of patients with acute CI. METHODS: The clinical characteristics and plasma D-dimer levels measured within 3 days of onset were compared according to outcome among patients with acute CI. RESULTS: In total, 359 consecutive patients (mean age, 71.8 years) were examined, of which 174 had a poor outcome [score on the modified Rankin scale (mRS) ≥3] at 30 days after hospitalization. The mean mRS score was higher and a poor outcome was observed more frequently among women than among men (p<0.001 for each). The proportions of women, cardioembolism, atrial fibrillation, advanced age (≥75 years), prior history of CI or transient ischemic attack, and elevated D-dimer level (≥1.0 µg/mL) were significantly higher among patients with a poor outcome than among those with a good outcome. A multivariate analysis showed that elevated D-dimer level [≥1.0 µg/mL; odds ratio (OR), 2.45; 95% confidence interval (95% CI), 1.52-3.89; p<0.01], advanced age (OR, 1.93; 95% CI, 1.21-3.07; p<0.01), and female gender (OR, 1.75; 95% CI, 1.08-2.83; p=0.02) were independent predictors of a poor outcome. CONCLUSIONS: Certain clinical characteristics (gender and advanced age) and an elevated D-dimer level upon admission can be used to predict the outcome of patients with acute CI at 30 days after hospitalization.
