Clonal Hematopoiesis of Indeterminate Potential in Crohn's Disease and Ulcerative Colitis.

Background: Clonal hematopoiesis of indeterminate potential (CHIP) is the presence of somatic mutations in myeloid and lymphoid malignancy genes in the blood cells of individuals without a hematologic malignancy. Inflammation is hypothesized to be a key mediator in the progression of CHIP to hematologic malignancy and patients with CHIP have a high prevalence of inflammatory diseases. This study aimed to identify the prevalence and characteristics of CHIP in patients with inflammatory bowel disease (IBD).

Prostate Cancer Patient With Lymph-node Metastasis Treated Only With Methionine Restriction Has Stable Disease for Two Years Demonstrated With PET/CT and PSMA-PET Scanning and PSA Testing.

Background/aim: Metastatic prostate cancer is a recalcitrant disease. Our laboratory has previously treated prostate-cancer patients with methionine restriction effected by a low methionine diet and oral recombinant methioninase (o-rMETase), both alone and in combination with other agents. The present case is a 66-year-old patient who had a radical prostatectomy in 2019 with a Gleason score 3+3 and 3+4.

Elevated-c-MYC-expressing Fibrosarcoma Cells With Acquired Gemcitabine Resistance Remain Sensitive to Recombinant Methioninase: A Potential Clinical Strategy for a Recalcitrant Disease.

Background/aim: For second-line chemotherapy of soft-tissue sarcoma, gemcitabine is administered in combination with docetaxel. However, more effective treatments are required for advanced soft-tissue sarcoma, where the efficacy is limited. The purpose of the present study was to compare the efficacy of rMETase and gemcitabine against HT1080 human fibrosarcoma cells and Hs27 normal fibroblasts, as well as to identify and effectively treat HT1080 cells that are resistant to gemcitabine associated with elevated c-MYC.

Complete Response (CR) in a Previously-progressing Chronic Lymphocytic Leukemia (CLL) Patient Treated With Methionine Restriction in Combination With First-line Chemotherapy.

Background/aim: Chronic lymphocytic leukemia (CLL) is currently incurable. CLL is characterized by disordered DNA methylation. The aim of the present study was to target methylation with methionine restriction in a patient with progressive CLL.

Subsequent pregnancies in the IMPAACT 2010/VESTED Trial: high rate of adverse outcomes in women living with HIV.

Introduction: Women with HIV (WHIV) have higher risks of adverse pregnancy outcomes, particularly in the absence of antiretroviral treatment(ART), and timing of ART may impact risk.

Methods: In IMPAACT 2010 (VESTED), 643 pregnant WHIV in 9 countries were randomized 1:1:1 to initiate ART: dolutegravir (DTG)+emtricitabine(FTC)/tenofovir alafenamide(TAF); DTG+FTC/tenofovir disoproxil fumarate (TDF) or efavirenz (EFV)/FTC/TDF. We describe adverse pregnancy outcomes in women with a subsequent pregnancy during 50 weeks of postpartum follow-up: spontaneous abortion (<20 weeks), stillbirth (≥20 weeks), preterm delivery (<37 weeks) and small-for-gestational-age (SGA).
