SALSANO, ETTORE. « Clinical and Genetic Characterization of Leukoencephalopathies in Adults ». Doctoral thesis, Università degli Studi di Milano-Bicocca, 2022. http://hdl.handle.net/10281/374739.
Texte intégralBackground In adults, many cases (about 30-40%) of leukoencephalopathies (LKENs), i.e. white matter (WM) diseases, are without definitive diagnosis. Patients who remain undiagnosed despite extensive investigations may have atypical forms of known acquired or genetic diseases, or novel diseases more likely genetic in nature. Aims of our work were to explore the efficiency of a systematic approach, including next generation sequencing (NGS), in the diagnosis of a cohort of adult patients with LKEN of unknown cause, and to describe their clinical features. Patients and Methods In this analytical observation study, we first reviewed the clinical and laboratory features of the adult patients (age >= 18 years) with undiagnosed LKEN assessed at the Unit of Rare Neurodegenerative and Neurometabolic Diseases of the Istituto Neurologico “C. Besta”, Milan, Italy, from 2012 to 2018. A targeted-gene panel sequencing (TGPS) was subsequently used to investigate 142 genes responsible for genetic LKENs, and a whole-exome sequencing (WES) was performed in one familial case remained undiagnosed. Results We identified 57 adult patients with LKEN of unknown cause (mean age 43 years, range 18-72; 23 males; 53 with late-adolescence or adult-onset). Thirty of them, henceforward called hypomyelinating leukoencephalopathies (HypoLKENs), presented an MRI pattern suggestive of hypomyelination (mild T2-hyperintensity and normal T1 signal), whereas the remaining 27 (henceforward called demyelinating leukoencephalopathies, DemLKENs) had an MRI pattern suggestive of demyelination (prominent T2-hyperintensity and prominent T1-hypointensity). In 13 HypoLKENs, TGPS identified the disease-causing genes, i.e., POLR3A (n = 2), POLR1C, TUBB4A, RARS1, GJA1, PLP1, GJC2, TBCD, CYP7B1, SPG11, PEX3, and PEX13, while in two further patients, WES led to the identification of a novel disease-causing gene (preliminarily called GENE_A). In contrast, TGPS identified the disease-causing gene (i.e., AUH) in only one (out of 27) DemLKEN patient affected by methylglutaconic aciduria type 1. In two other DemLKEN patients, the diagnosis was made on the basis of their clinical and MRI features directly by single gene analysis (PSAP-related metachromatic leukodystrophy), or by skin biopsy after negative results of TGPS (neuronal intranuclear inclusion disease, NIID). Three patients (one with HypoLKEN and two with DemLKEN) had acquired diseases mimicking a leukodystrophy, i.e., a primary cerebral vasculitis (diagnosed by brain biopsy without genetic analyses) and rare variants of multiple sclerosis, diagnosed after negative results of TGPS. Finally, in eight subjects with an incidentally found DemLKEN who remained without clinical manifestations over a long period of time, no mutation was found by TGPS. Conclusions In adults, a hypomyelinating pattern characterizes a large number (about 50%) of LKENs of unknown cause. HypoLKENs are most commonly due to genes causing severe early-onset hypomyelinating leukodystrophies (HLDs), such as POLR3A and TUBB4A, or can be due to genes associated with hereditary spastic paraplegias, such as CYP7B1 and SPG11, peroxisomal biogenesis disorders, such as PEX3 and PEX13, or even novel disease-causing genes. Among the DemLKENs of unknown cause, only very few are diagnosed by TGPS if clinical and paraclinical data pointing toward specific diagnoses are lacking. Occasionally, atypical variants of acquired WM diseases can mimic a genetic leukoencephalopathy with demyelinating or hypomyelinating features on MRI. Finally, a subset of DemLKENs characterized by lack of neurological manifestations and no mutation after comprehensive NGS testing may constitute a novel entity we termed subclinical diffuse leukoencephalopathy (SDL).

Texte intégralGuillain-Barré syndrome (GBS) is the prototype of a post-infective immune-mediated neuropathy. Patients with GBS after Campylobacter jejuni enteritis have anti-ganglioside antibodies and Campylobacter jejuni strains isolated from such patients have ganglioside-like structures in the lipopolysaccharide (LPS), supporting the hypothesis that anti-ganglioside antibodies, induced through molecular mimicry by the antecedent Campylobacter jejuni infection, attack gangliosides expressed in the human peripheral nerve. We isolated monocytes from 4 healthy subjects and 5 GBS patients. The patients had acute axonal motor neuropathy (AMAN) and had an antecedent Campylobacter jejuni infection. All patients had serum antibodies against GM1 and/or GD1a. Immature dendritic cells expressing CD1 molecules, cultured with autologous T cells, were stimulated with LPS obtained from two Campylobacter jejuni strains isolated from GBS patients and with GM1. The T cell response to LPS and to GM1 was determined by the release of the proinflammatory cytokines IFNg and TNFa. Our results show that in most cases where T cell reactivity to the gangliosides was determined, a tight correlation existed with a concomitant antibody response towards the same antigen. We find T cell response to gangliosides also in patients with multiple sclerosis desease. In conclusion, our data for the first time provides evidence of molecular mimicry at the level of the T cell response and suggests an important contribution of the cellular arm of the immune response in GBS.
