Pyrin responds to pathogen signals and loss of cellular homeostasis by forming an inflammasome complex that drives the cleavage and secretion of interleukin-1β (IL-1β). Mutations in the B30.2/SPRY domain cause pathogen-independent activation of pyrin and are responsible for the autoinflammatory disease familial Mediterranean fever (FMF). We studied a family… (More)
In the last decades, autoimmune diseases have experienced a dramatic increase in Western countries. The involvement of environmental factors is strongly suspected to explain this rise. Particularly, over the same period, obesity has followed the same outbreak. Since the exciting discovery of the secretory properties of adipose tissue, the relationship… (More)
We report a case of human African trypanosomiasis caused by Trypanosoma brucei rhodesiense. After the febrile period of parasite dissemination, the patient had meningeal involvement but normal CT. MRI showed the appearances of meningitis. After two periods of arsenical treatment, a severe encephalopathy occurred suggesting post-therapeutic reactive… (More)
Leptospirosis in Tahiti was studied during 1981. 42 cases were detected by positive blood cultures grown in Stuart's medium. The present paper describes the isolation of leptospira from the blood of four cases 30 days after the date of onset.
BACKGROUND The Hygiene Hypothesis (HH) attributes the dramatic increase in autoimmune and allergic diseases observed in recent decades in Western countries to the reduced exposure to diverse immunoregulatory infectious agents. This theory has since largely been supported by strong epidemiological and experimental evidence. DISCUSSION The analysis of these… (More)
Restrictive ventilatory dysfunction, lowered diffusing capacity, and apical fibrosis have been reported in ankylosing spondylitis. To investigate the pathogenesis of these abnormalities, we studied distal airspace cytology by performing bronchoalveolar lavage in 34 spondyloarthropathy patients (ankylosing spondylitis, n = 16; reactive arthritis, n = 4;… (More)
In a retrospective study of 60 cases of leptospirosis, the association of thrombocytopenia and acute renal failure as previously reported was confirmed. However, increased mortality, in our experience, was not associated with either thrombocytopenia or acute renal failure.
Only six of the many alphavirus known to affect humans can cause articular manifestations. They are the Ross River and Barmah Forest viruses from the South Pacific, the Chikungunya, O'Nyong Nyong and Sindbis viruses from tropical Africa, and the Mayaro virus from South America. In most cases, articular manifestations involve arthralgia or transient… (More)
