Tissue plasminogen activator for acute branch atheromatous disease exhibits transient improvement and worsening.

Background: Tissue plasminogen activator (tPA) is an effective treatment for acute ischemic stroke. Although initial improvement is observed when administered for branch atheromatous disease (BAD), some cases subsequently worsen. Clinical data on the characteristics of these patients is lacking, and the benefits of tPA are unclear.

[Peripheral neuropathy associated with severe glial fibrillary acidic protein (GFAP) astrocytopathy: a case report].

A 44-year-old man was admitted due to a fever. He developed unconsciousness and respiratory failure, necessitating mechanical ventilation. After the administration of methylprednisolone and intravenous immunoglobulin for suspected autoimmune encephalitis, his consciousness and respiratory state improved.

Bortezomib-dexamethasone versus high-dose melphalan for Japanese patients with systemic light-chain (AL) amyloidosis: a retrospective single-center study.

Bortezomib-dexamethasone (BD) and high-dose melphalan (HDM) are effective for systemic light-chain (AL) amyloidosis, but have not been compared in detail. We retrospectively investigated patients treated with BD or HDM at our center between September 2001 and June 2016. Among 234 patients, 20 were treated with BD and 30 received HDM.

Polyarteritis nodosa with central nervous system involvement mimicking relapsing-remitting multiple sclerosis.

We report a patient with polyarteritis nodosa (PN) who showed frequent episodes of acute-onset central nervous system (CNS) involvement mimicking relapsing-remitting multiple sclerosis (MS) for 22 years. Long-term use of oral prednisolone successfully avoided recurrence of neurological symptoms. PN can sometimes affect the CNS, and is an important item in the differential diagnosis of neurological manifestations with lesion dissemination in time and space, as seen in MS.

Patient with adult-onset type II citrullinemia beginning 2 years after operation for duodenal malignant somatostatinoma: Indication for liver transplantation.

We report a 51-year-old female patient with adult-onset type II citrullinemia (CTLN2) who had a history of pancreatoduodenectomy for duodenal somatostatinoma with metastases to regional lymph nodes at age 49 years, paying special attention to indications for liver transplantation. At age 50 years, she developed hepatic encephalopathy with elevation of plasma ammonia and citrulline levels. A diagnosis of CTLN2 was made by DNA analysis of the SLC25A13 gene and treatment with conservative therapies was begun, including a low-carbohydrate diet and supplementation with arginine and sodium pyruvate.

Coadministration of tacrolimus with corticosteroid accelerates recovery in refractory patients with polymyositis/ dermatomyositis: a retrospective study.

Background: To investigate whether or not coadministration of tacrolimus (TAC) with prednisolone (PSL) can produce a beneficial effect in the treatment of polymyositis/ dermatomyositis (PM/DM).

Methods: We reviewed medical records of 32 PM/DM patients who had been admitted to our hospital, and abstracted those who had received TAC in addition to oral PSL for treatment. The clinical usefulness of TAC in PM/DM was objectively evaluated focusing upon the manual muscle strength test (MMT) score, serum creatine kinase (CK) and tapering of PSL.

ANCA-associated vasculitis with central retinal artery occlusion developing during treatment with methimazole.

A 63-year-old woman suddenly developed central retinal artery occlusion following a slight fever while being treated with methimazole (MMI) for hyperthyroidism. She was diagnosed to have anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) based on increased inflammatory reactions with positive myeloperoxidase-ANCA in the serum. Her visual acuity remained low despite immediate treatment with corticosteroids and cyclophosphamide after cessation of MMI, which may have played a role in the pathogenesis of AAV.

First two cases of adult-onset type II citrullinemia successfully treated by deceased-donor liver transplantation in Japan.

We report the first two cases of adult-onset type II citrullinemia (CTLN2) successfully treated by liver transplantation from deceased donors in Japan. One patient was a 34-year-old female, who had suffered from depression since the age of 28 years and developed consciousness disturbance at 34 years old. The other patient was a 41-year-old man who began to experience consciousness disturbance with abnormal behavior at 37 years old.

Coadministration of cyclosporin a with prednisolone in acute interstitial pneumonia complicating polymyositis/dermatomyositis.

Objective: To investigate clinical effectiveness of prednisolone (PSL) and cyclosporin A (CyA), particularly continuous intravenous administration of the latter, in patients with interstitial pneumonia (IP) associated with polymyositis/dermatomyositis (PM/DM).

Methods: We reviewed the clinical findings and therapeutic outcomes of patients with PM/DM who had received PSL and CyA (PSL + CyA, n = 21 for DM and 2 for PM) or the former alone (n = 12 for DM and 7 for PM). All patients receiving PSL + CyA had active IP.

Surgical removal of amyloid-laden lymph nodes: a possible therapeutic approach in a primary systemic AL amyloidosis patient with focal lymphadenopathy.

We report a patient with primary systemic AL amyloidosis who suffered from remarkable bilateral cervical lymphadenopathy. Intensive chemotherapies, including two cycles of high-dose melphalan with autologous peripheral blood stem cell transplantation, were insufficiently effective for both the lymphadenopathy and amyloidogenic IgGλ-type M-protein in serum, but the patient showed complete haematological remission after extensive surgical removal of enlarged lymph nodes that had massive depositions of λ-type immunoglobulin light chain-derived amyloid. Lymphadenectomy may be a possible therapeutic approach with regard to both cosmetic and haematological aspects in primary systemic AL amyloidosis patients with focal lymphadenopathy.

Intestinal angina due to atherosclerosis in a 45-year-old systemic lupus erythematosus patient.

We report a patient with systemic lupus erythematosus (SLE) who developed progressive emaciation and postprandial abdominal pain with a 27-year history of corticosteroid treatment. The patient was diagnosed as having intestinal angina based on computed tomography that showed severe stenosis of the superior mesenteric artery (SMA) in addition to complete occlusion of the celiac and inferior mesenteric arteries. Histopathology of the SMA and abdominal aorta showed atherosclerosis with no vasculitis or thrombus formation.

Marked shrinkage of amyloid lymphadenopathy after an intensive chemotherapy in a patient with IgM-associated AL amyloidosis.

A male patient with primary AL amyloidosis who had been suffering from systemic lymphadenopathy with IgMkappa-type M-proteinemia received two courses of VAD and high-dose melphalan with in vivo elimination of CD20(+) cells using rituximab followed by autologous peripheral blood stem cell transplantation. Four years after complete hematological remission he showed marked reduction in size of the amyloid-laden lymph nodes. Deposits of AL amyloid may regress from the tissue if the chemotherapy succeeds in persistent inhibition of the production of an amyloidogenic immunoglobulin light chain.

Spinal nerve root hypertrophy on MRI: clinical significance in the diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy.

Objective: To investigate the clinical usefulness of measuring diameters of spinal nerve roots on magnetic resonance imaging (MRI) in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with regard to the diagnosis and estimation of neurofunctional impairment.

Patients And Methods: Fourteen patients with CIDP (mean age, 38.9+/-19.

Severity and progression rate of cerebellar ataxia in 16q-linked autosomal dominant cerebellar ataxia (16q-ADCA) in the endemic Nagano Area of Japan.

16q22.1-linked autosomal dominant cerebellar ataxia (16q-ADCA) is a recently defined subtype of ADCA identified by a disease-specific C/T substitution in the 5' untranslated region of the puratrophin-1 gene. In Nagano, the central mountainous district of the main island of Japan, 16q-ADCA and spinocerebellar ataxia type 6 (SCA6) are the most and second most prevalent subtypes of ADCA, respectively.

Long-term follow-up of plasma cells in bone marrow and serum free light chains in primary systemic AL amyloidosis.

Objective: Primary systemic AL amyloidosis arises from immunoglobulin light chains produced by plasma cell dyscrasia. To prospectively investigate the production of M-protein and plasma cells in bone marrow before and after chemotherapy, we performed flow cytometry and analysis of serum free light chains (FLCs).

Patients And Methods: Fifty-nine patients with primary systemic AL amyloidosis (mean age, 59.

Therapeutic outcome of cyclic VAD (vincristine, doxorubicin and dexamethasone) therapy in primary systemic AL amyloidosis patients.

Objective: Intensive chemotherapy targeting plasma cell dyscrasia has been recently employed for the treatment of primary systemic AL amyloidosis. We prospectively studied the clinical usefulness of cyclic VAD (vincristine, doxorubicin and dexamethasone) in patients with primary systemic AL amyloidosis who were ineligible for high-dose melphalan with autologous stem cell support.

Patients And Methods: Eight patients (mean age, 60.

Systemic AL amyloidosis mimicking rheumatoid arthritis.

We report a patient with myeloma-associated systemic AL amyloidosis who showed chronic polyarthralgia as the main symptom. The clinical picture was similar to that of rheumatoid arthritis with regard to symmetrical swelling with tenderness in multiple joints, but inflammatory reactions were almost normal and autoantibodies were negative. He was diagnosed as having systemic AL amyloidosis based on deposition of kappa-light chain-immunoreactive amyloid in biopsied tissue and Bence Jones protein in serum and urine.

Nephrotic syndrome due to primary systemic AL amyloidosis, successfully treated with VAD (vincristine, doxorubicin and dexamethasone) alone.

We report 3 patients with nephrotic syndrome ascribed to primary systemic AL amyloidosis that were successfully treated with VAD (vincristine, doxorubicin and dexamethasone) alone. M-protein in serum disappeared soon after VAD, and nephrotic syndrome gradually improved in parallel with a decrease in daily protein excretion in urine. Long-term follow-up of these patients showed neither relapse of nephrotic syndrome nor reappearance of M-protein.

Successful treatment with infliximab and low-dose methotrexate in a Japanese patient with familial Mediterranean fever.

We report a Japanese patient with familial Mediterranean fever (FMF) who was successfully treated with the anti-tumor necrosis factor (TNF)-alpha monoclonal antibody, infliximab, and low-dose methotrexate. This patient was diagnosed as having FMF based on periodic fever with polyarthralgia typical of this disease and heterozygous mutations in the MEFV gene. Conventional treatment, such as colchicine and reserpine, failed to sufficiently control the FMF attacks.
