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

This is an electronic version of an article published in Amyloid 2009, Vol. 16, No. 3 : Pages 183-185. Amyloid is available online at: http://informahealthcare.com/doi/pdf/10.1080/13506120903151825A male patient with primary AL amyloidosis who had been suffering from systemic lymphadenopathy with IgM kappa-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 amyloidogenic immunoglobulin light chains.ArticleAMYLOID. 16(3):183-185 (2009)journal articl

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 IgG lambda lambda-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 lambda lambda-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.ArticleAMYLOID-JOURNAL OF PROTEIN FOLDING DISORDERS. 18(2):79-82 (2011)journal articl

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. Both subtypes are classified into Harding's ADCA III, but little attention has been given to the differences in the severity and progression rate of cerebellar ataxia between 16q-ADCA and SCA6. We investigated the clinical severity and progression rate of cerebellar ataxia of 16q-ADCA patients using international cooperative ataxia rating scale and scale for the assessment and rating of ataxia and compared them with those of SCA6 patients. The age at onset was much higher in 16q-ADCA patients (60.1 +/- 9.8 years, n = 66) than in SCA6 patients (41.1 +/- 8.7 years, n = 35). Clinical features of 16q-ADCA were basically consistent with pure cerebellar ataxia, as well as in SCA6, but gaze-evoked nystagmus was observed less frequently in 16q-ADCA patients than in SCA6 patients. When compared at almost the same disease duration after onset, the severity of cerebellar ataxia was a little higher, and the progression rate seemed more rapid in 16q-ADCA patients than in SCA6 patients, but the differences were not significant.ArticleCEREBELLUM. 8(1):46-51 (2009)journal articl

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

Abstract 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. Results Nine patients with PM and 6 with DM were enrolled in this study. TAC was added because of difficulty in reduction of PSL in 12 patients and recurrence with corticosteroid-induced complications in the remaining 3. Both PM and DM patients showed significant increases in the MMT score and significant decreases in serum CK 1 to 3 months after starting TAC compared with before. Skin symptoms in a clinically amyopathic DM patient also improved 1 month after starting TAC. The daily dosage of PSL could be significantly reduced in both PM and DM after starting TAC compared with before. No serious adverse events ascribable to TAC occurred in any patients. Conclusion Additional use of TAC with PSL may safely promote improvement of PM/DM and also accelerate tapering of the latter.</p
