[Severe acute syphilitic hepatitis]. / Hépatite aiguë sévère d'origine syphilitique.

We report the case of a 23-year-old patient with very marked hepatic cytolysis (ASAT: 18N; ALAT: 44N) associated with biological icterus and mucocutaneous jaundice. Initially, no etiology was identified due to the absence of toxic consumption, the negativity of hepatotropic virus serologies and tests for autoimmune pathologies. Following the appearance of cutaneous signs three weeks after the onset of hepatic involvement, a syphilis serology was performed, which proved positive and led to the diagnosis of secondary syphilis. To our knowledge, only one case of hepatic syphilis with such intense hepatic cytolysis has been described. Usually, the hepatic damage is moderate, with transaminases not exceeding 5 times normal values. Syphilitic hepatitis is rare and occurs in less than 10% of syphilis cases. This case makes it possible to identify syphilis as a neglected etiology of acute hepatitis which should be considered in a context suggestive of infection even in the absence of skin signs.

Sarcoidosis, inorganic dust exposure and content of bronchoalveolar lavage fluid: the MINASARC pilot study.

Inhalation of mineral dust was suggested to contribute to sarcoidosis. We compared the mineral exposome of 20 sarcoidosis and 20 matched healthy subjects. Bronchoalveolar lavage (BAL) samples were treated by digestion-filtration and analyzed by transmission electron microscopy. The chemical composition of inorganic particles was determined by energy-dispersive X-ray (EDX) spectroscopy. Dust exposure was also assessed by a specific questionnaire. Eight sarcoidosis patients and five healthy volunteers had a high dust load in their BAL. No significant difference was observed between the overall inorganic particle load of each group while a significant higher load for steel was observed in sarcoidosis patients (p=0.029). Moreover, the building activity sub-score was significantly higher in sarcoidosis patients (p=0.018). These results suggest that building work could be a risk factor for sarcoidosis which could be considered at least in some cases as a granulomatosis caused by airborne inorganic dust. The questionnaire should be validated in larger studies. (Sarcoidosis Vasc Diffuse Lung Dis 2018; 35: 327-332).
