This cohort, the largest reported to date, increases the spectrum of knowledge on PBL, rarely described. However, specific guidelines to clarify treatment are lacking, and may improve the poor prognosis of this rare disease.

In October 2014, an outbreak of 12 autochthonous chikungunya cases, 11 confirmed and 1 probable, was detected in a district of Montpellier, a town in the south of France colonised by the vector Aedes albopictus since 2010. A case returning from Cameroon living in the affected district was identified as the primary case. The epidemiological investigations and the repeated vector control treatments performed in the area and around places frequented by cases helped to contain the outbreak. In 2014, the chikungunya and dengue surveillance system in mainland France was challenged by numerous imported cases due to the chikungunya epidemic ongoing in the Caribbean Islands. This first significant outbreak of chikungunya in Europe since the 2007 Italian epidemic, however, was due to an East Central South African (ECSA) strain, imported by a traveller returning from West Africa. Important lessons were learned from this episode, which reminds us that the threat of a chikungunya epidemic in southern Europe is real.

The present data do not support the use of ASCT for up-front consolidation for all patients with PTCL-NOS, AITL, or ALK-ALCL with partial or complete response after induction.

Ibrutinib, obinutuzumab plus venetoclax demonstrate synergy in pre-clinical models of mantle-cell lymphoma (MCL). OAsIs (NCT02558816), a single-arm multi-center prospective phase I/II trial, aimed to determine the maximum tolerated dose (MTD) of venetoclax in combination with fixed doses of ibrutinib and obinutuzumab, in relapsed MCL patients. At the venetoclax MTD, extension cohorts were opened for relapsed and untreated patients. Safety and efficacy were secondary objectives. Minimal residual disease (MRD) was assessed by allele-specific oligonucleotide-quantitative polymerase chain reaction (ASO-qPCR). Between Oct 14, 2015 to May 29, 2018, forty-eight patients were enrolled. No dose limiting toxicity (DLT) was reported, and venetoclax at 400mg per day was chosen for extension. Eighteen (75%) relapsed and 8 (53%) untreated patients experienced grade 3/4 adverse events (AEs). The complete response rate assessed by positron-emission tomography at the end of cycle 6 was 67% in relapsed and 86.6% in untreated patients. MRD clearance for evaluable patients was seen in 71.5% of relapsed (10 out of 14) and 100% of untreated MRD-evaluable patients (n=12), at the end of three cycles. The median follow-up (mFU) for relapsed patients was 17 months (range, 10 to 35). The 2-years PFS was 69.5% (95% CI, 52.9- 91.4%) and 68.6% (95% CI, 49.5- 95.1%) for OS. The mFU was 14 months (range, 5 to 19) for untreated patients, the 1-year PFS was 93.3% (95% CI, 81.5- 100%). Obinutuzimab, ibrutinib and venetoclax combination is well tolerated and provides high response rates including at the molecular level in relapsed and untreated MCL patients.
