ABSTRACT
INTRODUCTION: Haemophagocytic syndrome (HS) is a rare disease with a severe prognosis that is defined by clinical, laboratory and histopathological criteria. Infections represent the classical cause of HS. HS secondary to Mediterranean spotted fever (MSF) is rare with only a few cases being reported in the literature. OBSERVATIONS: We report two cases of HS secondary to MSF in 2 men aged 77 and 63 years presenting a febrile maculo-purpuric eruption with inoculation ulcer associated with laboratory abnormalities (cytopenia, elevated ferritin, hypertriglyceridaemia). Haemophagocytosis was present in 2 cases. Serology and PCR for Rickettsia conorii were positive and militated in favour of recent infection responsible for the diagnosis of MSF. DISCUSSION: The first case of HS was described in 1979. Sixteen cases of HS secondary to MSF are described in the literature. Cytopenia associated with hyperferritinaemia and hypertriglyceridaemia strongly suggests MSF complicated by HS. The prognosis depends on the time elapsed since diagnosis and host-specific factors. Immunosuppressants and antibiotics may be necessary to ensure healing. CONCLUSION: Rickettsioses can induce HS, and this potential complication with a severe prognosis must be known.

Immune checkpoint inhibitors (ICIs) can cause numerous and complex immune-related adverse events whose management need a multidisciplinary approach. Herein, we investigated 114 requests, mostly concerning patients suffering from lung cancer, that were submitted to the « ToxImmun ¼ multidisciplinary meeting in Eastern Occitania between December the 17th 2018 and January the 20th 2020. The leading reasons for the request concerned the putative causal link between immunotherapy and immune-toxicity and its management, followed by possible retreatment after temporary withdrawn because of adverse event, and finally the possibility to initiate ICIs in patients with pre-existing autoimmunity. Colitis, hepatitis and myocarditis were the most frequent immune-related adverse events (IRAEs), both all grade and grade 3-4. Sicca syndrome (with or without Sjogren criteria) was also frequent (26% of cases) and seems to be associated with severe toxicity and multi-toxicity. The mean time to first IRAE was 3.8 months, a time shortened with the use of anti-PD-L1 agents or ICI combination. A majority of requests came from initial evaluation by the internist confirming the early and main role of this specialty in the management of immunotoxicity. Expansion of this regional multidisciplinary meeting, coordinated by internists and medical oncologists, could improve management of immune-related adverse events for the patients' benefits.

The purpose of this report is to describe a case involving severe anemia in a patient from New Caledonia. Endoscopic discovery of adult hematophagic hookworms in mainland France is novel because it is exceptional. However, this case also reminds us that hookworm disease is extremely widespread in the world. It often goes unrecognized causing progressive, insidious anemia that can be severe though long-term tolerance is good.

INTRODUCTION: Acute pericarditis is a frequent hospitalization cause. A prospective, bicentric study aimed at different goals: population description, aetiologies screening, and evaluation of the interest of a coordinated and combined management between cardiologists and internists. PATIENTS AND METHODS: Between May 2005 and September 2007, all patients admitted for acute pericarditis were prospectively enrolled. Physical examination, ECG, echocardiography, biological screening were performed. Patients were asked to consult both cardiologist and internist, one month later. RESULTS: Hundred and three patients were enrolled (mean age 43 years). Clinical outcome was classical in 60% of cases. ECG was typical in 59%. Troponin elevation was noted in 30% of patients. CRP was normal at diagnosis in 27% of patients, and increased significantly at first day (P=0.002). Possible cause was identified in 44 patients. In 26 patients (24.3%), precise diagnosis was performed: six cancers, one hemopathy, three connectivities, one EBV and one parvovirus B19 seroconversions, two untreated HIV patients, four inflammatory diseases, three endocrinology troubles, one oesophagitis, one dental sepsis, one amyloidosis, one acute pancreatitis, one declined dialysis indication. Eighteen de novo diagnoses (16.5%) were performed, out of them at least 12 benefited from specific management. CONCLUSION: Population of patients admitted for acute pericarditis are very heterogeneous. Our co-management between internists and cardiologists aims to diagnose earlier and easier curable diseases. Long-term follow-up remains of great interest, in order to diagnose later other disorders, which remained hidden, and to follow evolution of the population.
