Severe (grade 3-5) adverse events were observed in 4 patients (13.3%). Nivolumab in a fixed dose of 40 mg was efficient in patients with r/r cHL, independent from dose per kg bodyweight. The results of this study are in good agreement with previously reported data and create a rationale for further studies aimed to define the optimal dosing regimen of nivolumab for the treatment of r/r cHL.

The recommendations of the French Innovative Leukemia Organization (FILO-CLL) group presented here are intended to provide practical recommendations for physicians taking care of CLL patients, taking into account the availability of both biological tests and therapies in daily practice in France at the time of publication. This text details the documented information and guidelines on diagnosis, indications for treatment, infectious complications and therapeutic strategies in frontline and relapsed CLL as well as in particular conditions such as autoimmune cytopenia or Richter syndrome.Peripheral T-cell lymphomas are a heterogeneous group of rare diseases with an aggressive behavior and dismal prognosis. Their classification is complex and still evolving, and several biomolecular markers now help refine the prognosis of specific disease entities, although still have limited impact in tailoring the treatment. First-line treatment strategies can cure only a minority of patients and relapsed-refractory disease still represents the major cause of failure. Frontline autologous transplantation may have an impact in the consolidation of response; however, its role is still questioned as far as complete responses obtained after induction chemotherapy are concerned. Newer drugs are now being evaluated in clinical trials, but effective salvage strategies for those who experience treatment failures are lacking. Here we review and discuss the most controversial aspects of diagnosis and treatment of peripheral T-cell lymphomas.Supplemental Digital Content is available in the text.The mouse (Mus musculus) has been extensively used for studying brucellosis, regarding pathogenesis, immunity and the evaluation of vaccines and therapeutics. In this work, RNA-seq was applied to explore the immunological potential of a live Brucella abortus S19∆per, a perosamine synthetase gene mutant of B. abortus S19. Comparison of transcriptome data was carried out for identifying differentially expressed genes among PBS (control) and B. abortus S19∆per immunized mice at 15 days post-immunization. Functional analysis revealed 545 significant differentially expressed genes related to mouse immunity. Specific activation of MHC-I and MHC-II antigen-processing pathways were identified as the highly enriched pathways based on Kyoto Encyclopedia of Genes and Genomes annotation. Other major immune response pathways regulated within the host were NF-kappa B signalling, chemokine signalling, T-cell receptor pathway, apoptosis, TNF signalling and nucleotide-binding oligomerization domain-like receptor signalling. These data provided new insights into the molecular mechanisms of B. abortus S19∆per-induced immune response in mice spleen that might facilitate the development of a highly immunogenic vaccine against brucellosis.

Invasive meningococcal disease (IMD) has a high rate of fatality and may cause severe clinical sequelae. Over the years, the epidemiology of IMD has changed significantly in various regions of the world, and laboratory surveillance of this disease is important for mapping epidemiologic changes.

To perform phenotypic characterization of

strains isolated from invasive disease in Brazil from 2002 to 2017, as a complementation of the data obtained in the period of 1990-2001.

In total, 8,689 isolates sent to Adolfo Lutz Institute confirmed as

by conventional methods were serogrouped by slide agglutination against MenA, MenB, MenC, MenE, MenW, MenX, MenY and MenZ; serotyped and serosubtyped by a whole-cell dot-blotting assay with monoclonal antibodies.

The isolates were sent from all regions of Brazil, and the southeast region was responsible for the largest number of isolates (57.2 %). Overall, the total sample (

=8,689) was represented by serogroups C (

=4,729; 54.4 %), B (

=3,313; 38.1 %), W (

=423; 4.9 %), Y (

=203; 2.3 %), X (

=5; 0.1 %) and others (

=16; 0.2 %). Tacrolimus cost A shift in the prevalence of serogroups was observed in 2006, when serogroup C became the most prevalent (65.5 %), surpassing the serogroup B (21.9 %). The main isolated phenotypes were C23P1.14-6; B4,7P1.19,15; W2aP1.5 and W2aP1.5,2.

The data show an important change in the distribution of meningococcal serogroups, serotypes and subtypes occurring during 2002-2017. A continuous laboratory-based surveillance provides robust information to implement appropriate strategies to IMD control.

The individual was found to have a foot wound infested with maggots, and clinical evidence of cellulitis. A blood culture was positive on day 2 with Ignatzschineria indica . The patient was treated successfully with a combination of antibiotics and manual removal of the maggots. Poor living conditions were central to his presentation.To better understand the prevalence of fluoroquinolone-resistant Escherichia coli among sheltered companion animals, we conducted a screening study of 38 dogs and 78 cats and investigated the resistance mechanisms and characteristics of the isolates. Fluoroquinolone-resistant E. coli was detected in 18 dogs (47.4 %) and 14 cats (17.9 %). The isolates carried one to four mutations in the gyrA, parC and parE genes of the quinolone resistance-determining region, and the number of mutations was proportional to the MIC for ciprofloxacin. For plasmid-mediated quinolone resistance, aac-(6')-Ib-cr was detected in nine isolates, qnrS in five isolates and qnrB in one isolate. A relationship between the presence of these genes and MIC for ciprofloxacin was not apparent. Statistical analysis indicated that fluoroquinolone-resistant E. coli was widely distributed among sheltered companion animals with various attributes. This may relate to the wide dissemination of fluoroquinolone resistance among humans and other animals in Japan.
