First experience of using Brentuximab vedotin and modified program NHL-BFM-90 in the front-line treatment of patient with anaplastic large-cell lymphoma: a case report and a review of literature

Nodal anaplastic ALK-negative large cell lymphoma (nALCL, ALK-) is a Т-cell lymphoma that is characterized by aggressive clinical course and low sensitivity to СНОР (cyclophosphamide, doxorubicin, vincristine, prednisolone) and other chemotherapy regimen. In the article we present a literature review and describe our clinical case of nALCL, ALK-. For the first time a combination of Brentuximab vedotin with modified program NHL-BFM-90 was used as a first-line therapy. As a result of immunochemotherapy a complete antineoplastic effect was obtained. For consolidation of this effect high-dose chemotherapy with following autologous blood stem cell transplantation was performed. The chosen treatment tactics allowed to achieve a complete remission in a medium risk group patient

Synthesis and Antimicrobial Activity of Sulfenimines Based on Pinane Hydroxythiols

The widespread presence of multidrug-resistant pathogenic microorganisms challenges the development of novel chemotype antimicrobials, insensitive to microbial tools of resistance. To date, various monoterpenoids have been shown as potential antimicrobials. Among many classes of molecules with antimicrobial activity, terpenes and terpenoids are an attractive basis for the design of antimicrobials because of their low toxicity and availability for various modifications. In this work, we report on the synthesis of sulfenimines from chiral trifluoromethylated and non-fluorinated pinane-type thiols. Final compounds were obtained with yields of up to 81%. Among the 13 sulfenimines obtained, 3 compounds were able to repress the growth of both bacteria (S. aureus, both MSSA and MRSA; P. aeruginosa) and fungi (C. albicans) with an MIC of 8–32 µg/mL. Although compounds exhibited relatively high cytotoxicity (the therapeutic index of 3), their chemotype can be used as a starter point for the development of disinfectants and antiseptics for targeting multidrug-resistant pathogens

A comparison of the forms of chronic lympholeukemia in relation to the mutational status of the genes of the immunoglobulin variable region

AIMTo compare forms of chronic lymphoid leukemia (CLL) regarding mutational status of immunoglobulin variable genes.MATERIAL AND METHODSWe have compared clinical, prognostic and immunophenotypic data obtained on 25 cases with different mutational status of IgV genes. There were 10 patients in the mutated group (median age 49.2 years, male to female ratio = 7:3), and 15 patients in unmutated group (median age 46.5, M:F = 13:2).RESULTSStatistically significant differences were noted in overall survival and CD38 expression. 5-year overall survival in unmutated group was 35%, in mutated group 80% (p = 0.07). In unmutated group CD38 was expressed on more than 50% of cells in 7 out of 14 patients, while in the mutated group in 0 of 8 patients (p = 0.007). We noted high frequency of VH1-69 gene usage in unmutated group (7 of 15 patients), while in mutated group it was used in only 1 case of 10.CONCLUSIONWe confirm the differences between groups of CLL with different mutational status of IgV genes. Highly restricted usage of VH-genes and CD38 expression possibly suggest that unmutated group also arises from antigen driven cells

POLYMORPHISM OF THROMBOPHILIA GENES AND THEIR ROLE IN DEVELOPMENT OF DIFFERENT DISEASE PHENOTYPES AND THROMBOTIC COMPLICATIONS IN HEMOPHILIA PATIENTS

Objective was to study genetic markers of thrombophilia in patients with hemophilia, which can affect the course of the disease and contribute to thrombotic complications. Material and methods. The study included 96 patients with severe hemophilia: 75 (78.1 %) – hemophilia A, 16 (16.7 %) – hemophilia B, 5 (5.2 %) – hemophilia with inhibitor form. All patients were with severe hemophilic arthropathyand and underwent knee or hip replacement. The average age of patients was 39.6 years. All patients were examined for markers of thrombophilia. Results. Ninety three patients had either a heterozygous or homozygous form of thrombophilia marker polymorphism. One of thrombophilia markers was present in 15 (15.6 %) patients and in 78 (81.3 %) there was a combination of several markers. In patients with hemophilia B homozygous mutations in the MTHFR gene (A1298C and C677T) were more than 2 times more frequent than in patients with hemophilia A. Conclusion. The frequency of occurrence of polymorphism of FV (G1691A), MTHFR (C677T) and PAI-1 in the studied group of patients with hemophilia is higher than in the general Russian population
