Association of MTHF 677TT with adverse drug reactions and RFC G80A with non-response and adverse drug reactions in methotrexate therapy

Publication date: July 2018Source: Personalized Medicine Universe, Volume 7Author(s): Manahel Mahmood AlSabbaghAbstractBeing an anti-metabolite and anti-inflammatory agent, Methotrexate, a folate analogue, is indicated for a wide spectrum of diseases including moderate to severe chronic inflammatory disorders like psoriasis and rheumatoid arthritis and malignant diseases such as childhood acute lymphoblastic leukaemia and choriocarcinoma. The outcome of Methotrexate treatment varies. Though up to 50% of patients with inflammatory disorders show a favourable response; one third discontinues Methotrexate due to adverse drug reactions or non-response. Such diversity suggests an inter-individual variation due to multiple factors including genetic polymorphisms. This review was conducted to identify genotypes predictive of Methotrexate treatment outcome. More than 15 alleles located in eight genes were explored by over 25 studies. Among those, we identified MTHFrs1801133TT genotype to be likely associated with adverse drug reactions and RFCrs1051266A allele to be associated with both, non-response and adverse drug reactions. We recommend the conduction of meta-analysis to verify these findings.

ConclusionsChoriocarcinomas can rarely originate outside of the female reproductive tract (non-gestational, primary choriocarcinomas). In the infrequent cases where a gestational origin is clinically unlikely, the differential diagnosis includes a non-gestational primary choriocarcinoma and choriocarcinomatous differentiation in another primary malignancy. Careful correlation with imaging and clinico-pathologic studies is paramount to determining their origin and guiding further clinical treatment.

ConclusionsPCPs report several barriers in providing care to hematologic malignancy/HCT survivors. Clinical experience with this patient population is associated with greater confidence in providing survivorship care. Several barriers identified by PCPs in providing survivorship care to hematologic malignancy/HCT survivors are potentially addressable by education, clinical decision support tools and guidelines, enhancing clinical experience, and care coordination with hematologist-oncologists.

The understanding of this chronic inflammatory skin disease remains unclear and all available treatments have their limitations currently. Here, we showed that IM...

Authors: Cui XF, Cui XG, Leng N Abstract Papillary renal cell carcinoma (PRCC) accounts for about 10 percent of all renal cell carcinomas, and the prognosis is poor for people with advanced disease. Interleukin-20 receptor subunit beta (IL20RB) is a single-pass type I membrane protein of the type II cytokine receptor family and is related to the pathogenesis of chronic inflammation and autoimmune diseases, including psoriasis, glaucoma, vitiligo, rheumatoid arthritis, and inflammatory bowel disease. However, little has been reported on IL20RB with respect to cancer, especially in PRCC. Thus, we performed this study...

AbstractThe immunohistochemical stain ERG is a useful diagnostic marker for leukemia cutis. Translocations involving theERG gene have been identified in acute myeloid leukemia (AML) and it plays critical roles in differentiation of hematopoietic stem cells. However, little is known about ERG expression in the bone marrow or in myeloid neoplasms. The aim of this study is to characterize ERG expression in normal bone marrow specimens, and those with various myeloid neoplasms. We performed immunohistochemical studies assessing ERG expression in bone marrow biopsies obtained over a 1-year period, in which myeloperoxidase (MPO)...

This study does not provide evidence for an increased skin cancer risk in patients treated with NB-UVB phototherapy. However, we have detected the occurence of 10 cases of solar lentigines. Still, definitive prospective longitudinal studies with a greater number of patients and prolonged follow-up are required to specifically address skin cancer risk in relation to NB-UVB phototherapy.

Abstract Our objective was to determine the association between the methylenetetrahydrofolate reductase polymorphisms (C677T and A1298C) and the risk of developing acute lymphoblastic leukemia (ALL), chronic myeloid leukemia (CML), acute myeloid leukemia (AML), and multiple myelomas (MM) in Latinos. PubMed, SCOPUS, EBSCO, LILACS, and other Latin-specific databases were searched for case-control studies that investigated the association between these polymorphisms and hematologic malignancies until November 2017. Genotype distributions were extracted and either fixed-effects or random-effects models were used to calculate t...

In this study, we used nanoString technology to design, validate, and evaluate a multiplex panel for detection of B-ALL fusion transcripts. Fifty-one B-ALL fusion transcripts reported in children in the literature were included in the design of the nanoString panel. Twenty-six fusion transcripts were validated using 64 positive control samples and 74 negative control samples with 100% sensitivity and 99% in comparison to Reverse Transcription-PCR. Our results support a potential role of nanoString as a robust and cost-effective technique that could be used in the detection of fusion transcripts and implemented in diagnosti...
