Acute onset of ulcerative colitis during chemoradiotherapy for anaplastic lymphoma kinase ‐positive lung adenocarcinoma

We report a case of acute onset of ulcerative colitis (UC) during chemoradiotherapy in a patient with anaplastic lymphoma kinase (ALK)‐positive lung adenocarcinoma. A 46‐year‐old male patient with an abnormal chest shadow was referred to our hospital. He was diagnosed with lung adenocarcinoma, clinical stage T1aN3M0 and stage IIIB. Concurrent chemoradiotherapy was selected for his initial therapy. After two cycles of cisplatin and vinorelbine administration, he experienced persistent diarrhoea and anorexia. Findings of the colonoscopy revealed a pancolitis type of UC. After discontinuation of chemotherapy, oral administration of mesalazine was initiated. The development of UC during chemotherapy is very rare and only a few case reports have been published. Although adverse events are rare, it is very important to assess the colitis precisely by performing a colonoscopy when protracted abdominal pain is experienced by the patient, along with diarrhoea or bloody stool during chemotherapy. Cytotoxic chemotherapy can cause various adverse effects involving the mucosa of the gastrointestinal tract. Although drug‐induced enterocolitis is a common phenomenon, ulcerative colitis (UC) is a very rare condition and only a few cases have been previously reported. Here, we discuss a case of acute onset UC during chemoradiotherapy in a patient with anaplastic lymphoma kinase‐positive non‐small cell lung cancer.

Authors: Chang C, Wu H, Lu Q Abstract Food allergy is a global health problem, particularly in developed countries. It is mainly mediated by Th2 cell and IgE produced by B cells. While the pathogenesis of IgE-mediated food allergy is quite straightforward, the factors that lead to the development of food allergies at any age in children and adults are unclear. Recent studies have revealed that genetics, epigenetics, and environmental exposures contribute to the development of atopy. In this chapter, we discuss the interplay between these three key elements, reveal how epigenetic modifications may mediate genetic su...

Authors: Ceribelli A, Selmi C Abstract Genomic predisposition fails to fully explain the onset of complex diseases, which is well illustrated by the largely incomplete concordance among monozygotic twins. Epigenetic mechanisms, including DNA methylation, chromatin remodeling, and non-coding RNA, are the link between environmental stimuli and disease onset on a permissive genetic background in autoimmune and chronic inflammatory diseases. Autoimmune diseases now include almost 100 conditions and are estimated to cumulatively affect up to 5% of the world population with a healthcare expenditure superior to cancer wor...

Authors: Zhang L, Lu Q, Chang C Abstract Epigenetic mechanisms, which include DNA methylation, histone modification, and microRNA (miRNA), can produce heritable phenotypic changes without a change in DNA sequence. Disruption of gene expression patterns which are governed by epigenetics can result in autoimmune diseases, cancers, and various other maladies. Mechanisms of epigenetics include DNA methylation (and demethylation), histone modifications, and non-coding RNAs such as microRNAs. Compared to numerous studies that have focused on the field of genetics, research on epigenetics is fairly recent. In contrast to ...
