Background: The role of the 43-kDa transactivation-responsive DNA-binding protein (TDP43) in neurodegenerative diseases is not yet clearly established. Objective: To assess for the first time the presence of TDP43 in a patient with motor neuron disease (MND) and Parkinson’s disease (PD). Methods: A 78-year-old woman developed poorly dopa-responsive parkinsonism without cognitive alteration. Three years later, MND appeared and led to death in less than a year. Neuropathologic examination was performed. Results: We observed the presence of PD and MND lesions with TDP43-positive cytoplasmic inclusions in the spinal cord and bulbar nuclei but not in the dentate gyrus and neocortex. The MND was characterized by a severe degeneration of bulbar and cervical lower motor neurons. Numerous senile plaques and topographically limited neurofibrillary tangles were also observed. Conclusion: The mechanisms underlying the rare co-occurrence of PD and MND are still unclear. The assessment of an abnormal reactivity for TDP43 in our case might gain more insight into the pathophysiology of this association of two diseases. Further studies are needed to confirm these findings and to understand the role of TDP43 in neurodegenerative diseases.

Facteurs de risque de la maladie d'Alzheimer : vers une prévention ?

Points essentiels Les etudes longitudinales recentes ont mis en evidence des associations epidemiologiques entre certains facteurs et la maladie d’Alzheimer (MA), notamment les facteurs de risque cardiovasculaires, comme l’hypertension arterielle, le diabete, les apports nutritionnels, l’obesite, l’hyperhomocysteinemie et les dyslipemies. Ils paraissent tous associes a un risque majore de survenue de MA incidente, tout particulierement l’hypertension arterielle et le diabete. Inversement, la consommation moderee d’alcool a pu etre associee a un risque minore de MA incidente. Le benefice cognitif du controle des facteurs de risque vasculaires a ete principalement etudie pour les antihypertenseurs et les statines avec des resultats encourageants. Les benefices d’autres mesures therapeutiques comme les anti-inflammatoires non steroidiens ou les antioxydants, restent incertains. Le traitement hormonal substitutif de la menopause ne semble pas confirmer les espoirs initiaux. Des mesures dites comportementales (activites physiques, sociales, cognitives) paraissent par contre diminuer le risque de MA incidente. L’interpretation de ces donnees doit neanmoins rester critique et integrer la possibilite de biais potentiels (facteurs confondants, biais de survie, bais de dilution du a la regression, biais d’indication). Ces donnees epidemiologiques remettent en question les limites nosologiques des diagnostics de MA et des demences vasculaires. Des travaux complementaires sont necessaires pour preciser ces notions novatrices et confirmer le benefice des mesures de prevention.

(L265P)) may be helpful because it is present only in WM. Computed tomographic scans of the chest, abdomen, and pelvis help to stage the disease. Beta 2 microglobulin levels and the WM International Prognostic Scoring System (IPSS) assist with prognostication. Indications for treatment include pancytopenia (hemoglobin <10 g/dL and platelets <100,000/lL), symptomatic hyperviscosity, moderate to severe peripheral neuropathy, cryoglobulinemia, cold agglutinin disease, and bulky adenopathy and splenomegaly. Chemotheraputic agents for primary therapy include monoclonal antibodies (rituximab and alemtuzumab), proteasome inhibitors (e.g., bortezomib), alkylating agents (cyclophosphamide and chlorambucil), nucleoside analogues (fludarabine and cladribine), and immunomodulators such as thalidomide. Rituximab may be associated with an IgM flare that may worsen symptoms of hyperviscosity. Individuals with such symptoms should receive prophylactic plasmapheresis if their IgM levels are greater than 5 g/dL. Individuals with symptomatic hyperviscosity, moderate to severe pancytopenia, peripheral neuropathy, and cryoglobulinemia should receive early plasmapheresis for immediate disease control, followed by chemotherapy. A widely used regimen involves rituximab, bortezomib, and dexamethasone, as in the individual described above. Treatment response is assessed according to IgM levels, bone marrow examination, resolution of symptoms and evidence of adenopathy or organomegaly. Individuals who have a complete response may then be observed until disease progression or initiated on rituximab maintenance therapy. Median survival varies from 60 to 120 months.

Corrélats anatomocliniques au cours de la démence de la maladie de Parkinson

Michèle Kiesmann; Thomas Vogel; Georges Kaltenbach; Michel Mohr

INTRODUCTION Cognitive disorders such as deficit of attention and executive and visuoconstructive dysfunctions occur in Parkinsons disease dementia (PDD). Memory impairment is not an early feature and statement not well delimited. CASE REPORT A 78-year-old man with PDD underwent neuropsychological assessment and moreover demonstrated memory decline. After death, pathology examination of the brain and immunohistochemy analysis confirmed PD and showed Lewy body pathology (LBP) in the insula, limbic and especially in CA3 hippocampus areas. Hippocampus and gyrus parahippocampic also exhibited neurofibrillary tangles. Lack of senile plaque and lack of beta A4 amyloid deposition were noticeable in the whole brain examination. CONCLUSION Severe executive dysfunctions are probably related to LBP and dysfunction in memory process may be related to DNF lesions in medial temporal area.

V - 5 La démence à corps de Lewy diffus (DCL) et la démence parkinsonienne (DP) : aspects communs cliniques, scintigraphiques et histopathologiques

Introduction L’examen histopathologique du cerveau de deux patients decedes et suspects de DP et de DCL selon des criteres cliniques et scintigraphiques permet d’argumenter le diagnostic etiologique de demence. Observations Cas 1 (05-061310930) : Un patient de 80 ans avec un syndrome akineto-hypertonique intolerant a la levodopa developpait un an plus tard des troubles cognitifs fluctuants et des hallucinations. Il presentait une DCL probable avec a la TEMP une hypofixation severe du traceur dopaminergique (calcul de ratio : rapport noyau caude/occipital a 1,5 a droite et 1,7 a gauche pour une normale > a 2,5) et une hypoperfusion corticale diffuse. L’examen histopathologique retrouvait de tres nombreux corps de Lewy dans le tronc cerebral et le cortex ou ils etaient diffus, associes a des lesions de MA au stade IV de Braak et Braak. Cas 2 (06-0666783587) : Un patient de 77 ans avait depuis douze ans une MP arrivee au stade IV de Hoehn et Yahr et traitee par 700 mg de levodopa et 25 mg de clozapine. Depuis quatre ans avaient debute des troubles cognitifs suivis d’hallucinations, de delires et d’une demence. La TEMP mettait en evidence une hypofixation severe du traceur dopaminergique (ratio : 1,4 a gauche et 1,5 a droite) avec une hypoperfusion corticale majeure. L’examen histologique montrait des corps de Lewy dans le tronc cerebral et des corps de lewy dans le cortex ou ils etaient diffus ainsi que des lesions de MA au stade V de Braak et Braak. Discussion Dans ces deux cas la DP et la DCL presentent de nombreux aspects similaires : 1) cliniques (troubles cognitifs dysexecutifs avec hallucinations, delires et syndrome parkinsonien, 2) scintigraphiques (aspect en TEMP cerebrale au 99mTc-ECD et au 123-I-FP-CIT ou DATscan) et 3) histopathologiques. Il est interessant de noter dans les deux cas, l’association de lesions de type Parkinson et de type Alzheimer. Conclusion Les similitudes importantes constatees dans nos cas entre la Demence a Corps de Lewy et la Demence Parkinsonienne font remettre en question les criteres encore utilises pour les differencier.
