    We report 2 cases of leishmaniasis in patients with autoimmune rheumatic diseases in Greece. To assess trends in leishmaniasis reporting in this patient population, we searched the literature for similar reports from Europe. Reports increased during 2004–2008, especially for patients treated with anti–tumor necrosis factor agents

    Hypoparathyroidism in a patient presenting with severe myopathy and skin rash. Case report and review of the literature.

    No full text
    A 47-year old man with idiopathic hypoparathyroidism (IHP), presented as severe myopathy and skin rash is described. The serum muscle enzymes were increased. After treatment with calcium and vitamin D, the clinical condition improved, the skin rash gradually disappeared, and the muscle enzymes decreased and remained within the normal range thereafter

    Autopathogenic correlation of periodontitis and rheumatoid arthritis

    Recently, a number of studies have pointed to a potential relationship between periodontitis (PO) and RA and vice versa. Both diseases are characterized by chronic inflammation, osseous destruction, damage of the supporting soft tissues, similar cellular immune responses and common immunogenetic findings. Although a definite, methodological report associating these diseases is missing from the literature, it is possible that both diseases share a common aetiopathogenic background. This background includes the post-translation modification citrullination, which guides the conversion of the amino acid arginine to citrulline in certain self-proteins, generating neo-epitope structures. This results in reduced self-tolerance, development of autoimmunity and the production of ACPAs. The current hypothesis suggests that certain oral bacteria induce the citrullination of proteins under the action of the enzyme peptidyl arginine deiminase (PAD), which exists in both Porphyromonas gingivalis and inflammatory cells. Antibodies against citrullinated proteins and peptides constitute a common serological finding in both RA and PO. The aim of this review is to map the immunological and serological profiles of PO, and to unveil the parameters that connect PO with the appearance of RA at clinical, prognostic and pathogenetic levels. Until now, there have been no reports sufficiently mapping the immunological profile of PO and defining its aetiopathogenic connection with RA, although a similarity between the immunological profile of PO and RA is highly expected. © The Author 2011.

    Extended fungal skin infection due to Aureobasidium pullulans

    Black yeasts are a rare cause of infections especially in Europe, yet their pathological significance is increasing, particularly in cases of immunosuppression. We report a 53-year-old immunocompetent woman with an extensive skin infection due to Aureobasidium pullulans, who responded well to treatment with liposomal amphotericin B. © 2008 British Association of Dermatologists

    Trial of canakinumab, an IL-1β receptor antagonist, in patients with inclusion body myositis

    ObjectiveTo assess whether canakinumab, a monoclonal antibody against IL-1β approved for autoinflammatory diseases, is effective as target-specific therapy in patients with sporadic inclusion body myositis (sIBM).MethodsBecause in sIBM IL-1β colocalizes with amyloid precursor protein and upregulates amyloid aggregates enhancing degeneration, targeting IL-1β with canakinumab may arrest disease progression. On this basis, 5 ambulatory patients with sIBM participated in an institutional review board-approved open-labeled study with 150 mg canakinumab [4 bimonthly, then monthly subcutaneous injections] for a mean period of 15.8 months. Patients were assessed bimonthly with a manual dynamometer in 12 proximal and distal muscles and with grip force (GF) in both hands. Total muscle strength (TMS) was expressed in kilograms. Efficacy was defined as >15% increased strength after 12 months.ResultsPatient 1 stopped at month 5 because of 23% loss in TMS and 32.35% in GF; patient 2 showed 37.1% increase in TMS and 13% in GF by month 9; patient 3 exhibited 26.7% reduction in TMS and 10% in GF at month 33; patient 4 showed 6.5% reduction in TMS and 1.6% in GF after 15 months, denoting relative stability; and patient 5 showed 30.4% loss in TMS and 20.8% in GF after 18 months. In patients 2 and 4, in whom 3-year longitudinal data were available, no effect on disease progression was noted.ConclusionsIn this long-term, open-label study, canakinumab showed small, but not clinically appreciable, stabilizing benefits in 2 of 5 patients with sIBM over 1 year, was ineffective in 2 others, and might have worsened one. No patient improved.Classification of evidenceThis study provides Class IV evidence that canakinumab was ineffective for patients with sIBM. © 2019 American Academy of Neurology
