Multicenter Study
[Detection of activating mutations in RAS/RAF/MEK/ERK and JAK/STAT signaling pathways].
The study of activating mutations (NRAS,KRAS,FLT3,JAK2,CRLF2genes) of RAS/RAF/MEK/ERK and JAK/STAT signaling pathways in B-cell acute lymphoblastic leukemia (B-ALL) in adult patients which are included in Russian multicenter clinical trials. ⋯ NRAS,KRAS,FLT3,JAK2activating mutations do not affect the long-term results of the therapy and the rate of the negative status achievement of the minimum residual disease in patients withBCR-ABL1-negative B-ALL treated by the Russian multicenter clinical trials.

Currently, the main pathogenetic method for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) is the treatment with recombinant monoclonal antibodies that block the C5 component of the complement system. Eculizumab is the first biotechnological drug, which is a monoclonal antibody, with proven clinical efficacy and safety for the treatment of patients with PNH, which is used in world clinical practice. In Russia, in the framework of the state program Development of the pharmaceutical and medical industry for 20132020 was developed Elizaria (JSC GENERIUM) the first biosimilar of the original drug eculizumab.

Was to evaluate clinical efficacy, adverse events and changes in the gut microbiome after fecal microbiota transplantation (FMT) in patients with gastrointestinal (GI) form of graft-versus-host disease (GVHD). ⋯ FMT in patients with refractory GI GVHD was associated with favorable clinical outcomes and recovery in certain marker bacterial populations. Multiplex PCR can be used to assess an engraftment of a donor microbiota. FMT in GI GVHD was not associated with life-threatening adverse events, but further studies are required to validate clinical efficacy.

Our case demonstrates severe bone disease in primary AL-amyloidosis without concomitant multiple myeloma. A 30-year-old man had spontaneous vertebral fracture Th8. A computed tomography scan suggested multiple foci of lesions in all the bones. ⋯ There was also spontaneous scarring of the some lesions (without therapy). Thus, the diagnosis of multiple myeloma was excluded on the basis based on x-ray signs, of the duration of osteodestructive syndrome (15 years), the absence of plasma infiltration in the bone marrow, including from foci of bone destruction by open biopsy. This observation proves the possibility of damage to the skeleton due to amyloid deposition and justifies the need to include AL-amyloidosis in the spectrum of differential diagnosis of diseases that occur with osteodestructive syndrome.

POEMS syndrome is a rare paraneoplastic syndrome whose name is an acronym formed from the initial letters of the names of the symptoms originally used to determine it: polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes. Due to the rarity of the disease and the small number of cases described in the literature, its diagnosis is difficult. ⋯ Moreover, the prognosis of the disease depends on the early onset of specific treatment. The article describes a clinical case of POEMS-syndrome in a 53-year-old man, which illustrates the difficulties associated with the timely recognition of this unusual disease.
