Abstract
In different areas of the heart, action potential waveforms differ due to differences in the expressions of sodium, calcium, and potassium channels. One of the characteristics of myocardial infarction (MI) is an imbalance in oxygen supply and demand, leading to ion imbalance. After MI, the regulation and expression levels of K+, Ca2+, and Na+ ion channels in cardiomyocytes are altered, which affects the regularity of cardiac rhythm and leads to myocardial injury. Myocardial fibroblasts are the main effector cells in the process of MI repair. The ion channels of myocardial fibroblasts play an important role in the process of MI. At the same time, a large number of ion channels are expressed in immune cells, which play an important role by regulating the in- and outflow of ions to complete intracellular signal transduction. Ion channels are widely distributed in a variety of cells and are attractive targets for drug development. This article reviews the changes in different ion channels after MI and the therapeutic drugs for these channels. We analyze the complex molecular mechanisms behind myocardial ion channel regulation and the challenges in ion channel drug therapy.

Abstract
Gastrointestinal fistulation has been widely reported as an adverse effect of nicorandil therapy in Europe. People who have underlying diverticular disease are most at risk of this side effect. In Western countries, diverticular disease is highly prevalent and can be clinically silent. This study aimed to identify diverticular disease genetic risk scores (GRSs) associated with early nicorandil stoppage, a surrogate marker for drug intolerance. A case-control study was carried out on 1,077 patients from the Genetics of Diabetes Audit and Research Tayside Scotland (GoDARTS) database. Cases were defined as having < 9 nicorandil prescriptions with no identifiable reason for stopping (n = 230). Controls had either ≥ 9 prescriptions, treatment continuation to death/study end or stoppage post-myocardial infarction. Two diverticular GRSs were created and used in logistic regression models. Isosorbide mononitrate was used as a control analysis. Patients with a raised diverticular GRS, based on 23 replicable loci, had increased risk of stopping nicorandil therapy early (univariate (odds ratio (OR) 2.26; P = 0.04], multivariate (OR 3.96; P = 0.01)). Similar trends were noted when using the full 42 variant diverticular score but statistical significance was not reached. The isosorbide control analysis did not reach statistical significance. Our analysis demonstrates a novel positive association between a raised diverticular GRS and early stoppage of nicorandil therapy.

Abstract
PURPOSE OF REVIEW Increasing use of small bowel endoscopy unravels ulcers in a relevant number of patients. Although often attributed to inflammatory bowel disease (IBD), these ulcers may be unspecific or caused by a variety of other diseases. This review summarizes the recent literature related to differential diagnosis of small bowel ulcers. RECENT FINDINGS NSAID enteropathy is the major differential diagnosis to IBD in patients with small bowel ulcers. Intestinal tuberculosis must be considered in patients at risk. Rare causes for small bowel ulcers are autoinflammatory, neoplastic, vascular diseases, or nontuberculous infections. Morphology of small bowel ulcers cannot provide a reliable differentiation, and even histology is not specific in all cases. History with special focus on NSAID medication and clinical symptoms not typical for IBD, laboratory tests in the search of systemic disease, and microbiologic testing of biopsies can be helpful. Genetic testing allows identification of few rare entities like defects in prostaglandin metabolism. SUMMARY Due to a massive overlap in the endoscopic appearance of small bowel ulcers between possible causes, diagnosis should be based on broad information also including history, histology, imaging, and laboratory tests.

Curr Drug Saf 2019; 14:147-150. [PMID: 30648521 DOI: 10.2174/1574886314666190114124625] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Revised: 12/31/2018] [Accepted: 01/03/2019] [Indexed: 01/22/2023]
Abstract
BACKGROUND Either direct or indirect tumor necrosis factor (TNF)-alpha blockers are usually used to treat psoriatic arthritis (PA), but their use can increase susceptibility to infectious diseases. CASE PRESENTATION We report a rare case of double skin-knee wound and lung non-tubercular infection in a patient with PA under TNF-alpha blockers therapy. About 1 year after the beginning of adalimumab, a 48-year-old smoker suffering of PA was hospitalized for the skin-knee wound. RESULTS Clinical evaluation and biochemical markers excluded the presence of a systemic disease, and a skin infection sustained by leishmaniasis probably related to adalimumab was diagnosed (Naranjo score: 6). Adalimumab was discontinued and oral treatment with apremilast and topical treatment with meglumine antimoniate was started with a complete remission of skin wound in 2 weeks. About 7 months later when the patient was under apremilast treatment, he presented to our observation for dyspnea, cough and fever. High-Resolution Computer Tomography (HRCT) chest highlighted alveolar involvement with centrilobular small nodules, branching linear and nodular opacities. Microbiological culture of both broncho-alveolar lavage fluid and sputum documented an infection sustained by nontuberculous mycobacteria. Even if apremilast treatment probably-induced lung infection, we can't exclude that it worsened a clinical condition induced by adalimumab. Apremilast was stopped and an empirical antitubercular treatment was started. Patient's breathlessness and cough improved as confirmed also by HRCT chest. CONCLUSION This case highlights the importance to consider the possibility to develop leishmaniasis and/or non-tubercular mycobacterial infection in patients treated with TNF-alpha inhibitors.
