Hsp60 and AChR cross-reactivity in myasthenia gravis: An update.
2010
Clinical characteristics and outcomes of thymoma-associated myasthenia gravis
2021
[Background and purpose] Prognosis of myasthenia gravis (MG) in patients with thymoma is not well established. Moreover, it is not clear whether thymoma recurrence or unresectable lesions entail a worse prognosis of MG.
The impact of rituximab infusion protocol on the long-term outcome in anti-MuSK myasthenia gravis
2018
ObjectiveTo evaluate whether the clinical benefit and relapse rates in anti-muscle-specific kinase (MuSK) myasthenia gravis (MG) differ depending on the protocol of rituximab followed. MethodsThis retrospective multicentre study in patients with MuSK MG compared three rituximab protocols in terms of clinical status, relapse, changes in treatment, and adverse side effects. The primary effectiveness endpoint was clinical relapse requiring a further infusion of rituximab. Survival curves were estimated using Kaplan-Meier methods and survival analyses were undertaken using Cox proportional-hazards models. ResultsTwenty-five patients were included: 11 treated with protocol 4 + 2 (375 mg/m(2)/4 w…
Impact of Safety-Related Dose Reductions or Discontinuations on Sustained Virologic Response in HCV-Infected Patients: Results from the GUARD-C Cohor…
2015
Background: Despite the introduction of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, peginterferon alfa/ribavirin remains relevant in many resource-constrained settings. The non-randomized GUARD-C cohort investigated baseline predictors of safety-related dose reductions or discontinuations (sr-RD) and their impact on sustained virologic response (SVR) in patients receiving peginterferon alfa/ribavirin in routine practice. Methods: A total of 3181 HCV-mono-infected treatment-naive patients were assigned to 24 or 48 weeks of peginterferon alfa/ribavirin by their physician. Patients were categorized by time-to-first sr-RD (Week 4/12). Detailed analyses of the i…
The prevalence of post-thyroidectomy chronic asthenia: a prospective cohort study
2017
Chronic asthenia (CA) is complained by some patients that have undergone thyroid surgery. We evaluate its impact in patients undergoing unilateral or bilateral thyroidectomy, the trend during a 1-year follow-up, and the possible risk factors. A prospective, cohort study was carried out on 263 patients scheduled for thyroidectomy from 2012 and 2014. Exclusion criteria were as follows: Graves’ disease, malignancies requiring radioiodine therapy, post-surgical hypoparathyroidism, laryngeal nerve palsy, abnormal pre- and post-operative thyroid hormone levels, and BMI outside the normal range. Demographics; smoking and alcoholism addiction; cardiac, pulmonary, renal, and hepatic failure; diabete…
Five years experience on 3,4-diaminopyridine phosphate in Lambert-Eaton syndrome: Case reports
2017
Abstract Rationale: To report our experience on 7 patients (4 males and 3 females), affected by nonparaneoplastic Lambert–Eaton myasthenic syndrome, treated with 3,4-diaminopyridine phosphate (3,4-DAPP) either alone or in combination with other immunosuppressants or steroids. Patient concerns: Patients have been evaluated at specific timepoints (ie, baseline and last 5 year follow-up), with neurological examination, autoantibodies against presynaptic voltage-gated Cav2.1 (P/Q type) calcium ion channel (VGCC) dosage, neurophysiological evaluation focusing on the increased amplitude of the compound muscle action potential (cMAP) after maximum voluntary effort, quantitative myasthenia gravis (…
Bilateral thoracoscopic thymectomy using a novel positioning system.
2013
Several techniques of bilateral video-assisted thoracoscopic extended thymectomy have been proposed, and each has its own proponents. We summarize our experience in 20 patients who underwent bilateral video-assisted thoracoscopic extended thymectomy, using a new patient positioning that amplifies the thoracoscopic view of the cardiophrenic regions which are often difficult to visualize with standard techniques. In all cases, en-bloc thymectomy with complete dissection of the mediastinal fatty tissue was achieved without sternal retractors or additional incisions.
Good's syndrome and recurrent leishmaniasis: A case report and review of literature
2020
We report the case of a 56-year-old Caucasian male affected by thymoma and myasthenia gravis that developed recurrent visceral leishmaniasis 11 years after thymectomy. After treatment of each relapse with liposomal amphotericin B the PCR-Leishmania was negative and the patient showed clinical improvement. An immunologic work-up was performed showing lymphopenia with an important decrease in CD4+ T cells (52 cells/μ) and CD4/CD8 ratio (0.2). HIV test was negative. On the basis of previous thymoma and myasthenia gravis and on the basis of the immunological profile a diagnosis of Good's syndrome was made. Since IFNγ plays a main role in the control of Leishmania infection the production of IFN…
Other Types of Chaperonopathies
2013
A mechanism causing a chaperonopathy that is introduced in this chapter consists of the absence of a chaperone from the place where it is needed (i.e., chaperonopathies by misplacement). Also in this chapter are discussed the unfolded-protein response (UPR), chaperone-mediated autophagy (CMA), and illustrative examples of chaperonopathies by mistake, or collaborationism. In these conditions, one or more chaperones, apparently normal in structure, perform functions that favor disease rather than the contrary, hence the name of chaperonopathy by mistake or collaborationism (a molecule that ought to protect the cell and the organism promotes pathogenesis instead). Many examples of chaperonopat…
Drug‐refractory myasthenia gravis: Clinical characteristics, treatments, and outcome
2022
[Objective] To describe the clinical characteristics and outcomes in patients with refractory myasthenia gravis (MG) and to determine the effectiveness and side effects of the drugs used for their treatment.
