Review
Mesalamine, known as 5-aminosalicylic acid, is a medication used primarily in the treatment of inflammatory bowel disease, including ulcerative colitis and Crohn's disease. 5-Aminosalicylic acid can be measured using various benchtop laboratory techniques which involve liquid chromatography-mass spectroscopy, but these are sophisticated and large, meaning that they cannot be used on-site because transportation of the samples, chemicals, and physical and biological reactions can potentially occur, which can affect the sample's composition and potentially result in inaccurate results. An alternative approach is the use of electrochemical based sensing platforms which has the advantages of portability, cost-efficiency, facile miniaturization, and rapid analysis while nonetheless providing sensitivity and selectivity. We provide an overview of the use of the electroanalytical techniques for the sensing of 5-aminosalicylic acid and compare them to other laboratory-based measurements. The applications, challenges faced, and future opportunities for electroanalytical based sensing platforms are presented in this review.

Mesalamine is a first-line drug used in the treatment of inflammatory bowel disease (IBD), specifically ulcerative colitis (UC), with side effects ranging from gastrointestinal effects to cardiotoxicity. We present a rare case of mesalamine-induced myopericarditis in a patient with IBD, who presented with epigastric pain and was found to have elevated an c-reactive protein (CRP) in the absence of chest pain and any other gastrointestinal symptoms. This case highlights the importance of including myopericarditis as a differential for IBD patients on mesalamine with an isolated elevated CRP, especially within the first month of initiating this medication, as drug cessation usually leads to immediate clinical improvement.

BACKGROUND
Intestinal nontuberculous mycobacteriosis due to nontuberculous mycobacteria infection has clinical manifestations similar to intestinal tuberculosis and inflammatory bowel disease, causing difficulties in clinical diagnosis.
CASE PRESENTATION
A 42-year-old male patient was admitted to the Sino-Japanese Friendship Hospital of Jilin University in June 2021 for diarrhea and intermittent hematochezia since April 2021. He was diagnosed with inflammatory intestinal disease by colonoscopy and midtransverse colon biopsy. However, the symptoms did not relieve after 2 months of mesalazine treatment. In August 2021, the patient was admitted to the outpatient department for suspected "intestinal tuberculosis." A diagnosis of intestinal nontuberculous mycobacteriosis was confirmed based on pathology and nucleotide-based matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS). After 2 weeks of antimycobacterial therapy, the patient's diarrhea was relieved, and hematochezia no longer appeared. In November 2021, recolonoscopy revealed scattered erosions and ulcers in ileocecal valve and ascending colon, while both nucleotide-based MALDI-TOF MS and next-generation sequencing could still detect Mycobacterium intracellulare.
CONCLUSION
This study reported a patient with an intestinal nontuberculous mycobacteriosis diagnosed by colonoscopy biopsy and nucleotide-based MALDI-TOF MS, and symptoms were relieved after antimycobacterial treatment.

Mesalazine, a preparation of 5-aminosalicylic acid, is a medication widely used in clinical practice as a first-line therapy in the treatment of mild and moderate inflammatory bowel disease. However, the long-term safety of mesalazine in large sample population was unknown. The current study was to assess mesalazine -related adverse events of real-world through data mining of the US Food and Drug Administration Adverse Event Reporting System (FAERS). Disproportionality analyses, including the reporting odds ratio (ROR), the proportional reporting ratio the Bayesian confidence propagation neural network and the multi-item gamma Poisson shrinker (MGPS) algorithms were employed to quantify the signals of mesalazine -associated AEs. Out of 14,149,980 reports collected from the FDA Adverse Event Reporting System database, 24,284 reports of mesalazine -associated AEs were identified. A total of 170 significant disproportionality preferred terms conforming to the four algorithms simultaneously were retained. The most common AEs included colitis ulcerative, diarrhoea, condition aggravated, crohn's disease, fatigue, abdominal pain, nausea, haematochezia, which were corresponding to those reported in the specification and clinical trials. Unexpected significant AEs as dizziness, drug ineffective, drug hypersensitivity, infection, off label use, weight decreased, decreased appetite, arthralgia, rash might also occur. The median onset time of mesalazine -related AEs was 1,127 days (interquartile range [IQR] 1,127-1,674 days), and most of the cases occurred 2 years later (n = 610, 70.93%) and within the first 1 month (n = 89, 10.35%) after mesalazine initiation. Results of our study were consistent with clinical observations. We also found potential new and unexpected AEs signals for mesalazine, suggesting prospective clinical studies were needed to confirm these results and illustrate their relationship. Our results could provide valuable evidence for further safety studies of mesalazine.

Mesalazine is a drug used to treat ulcerative colitis and Crohn's disease, and is known to rarely cause lung injury. We show herein a unique case who developed this drug-induced injury. A 17-year-old boy presented with fever and anorexia after administration of mesalazine. Computed tomography showed extensive ground-glass opacities with peripheral distribution in both lungs. He had general weakness, but had no respiratory symptoms such as cough and dyspnea. With prednisolone, which is primarily aimed at controlling ulcerative colitis, the extensive opacity in both lungs were improved. All patients with this drug-induced lung injury reported to date have had respiratory symptoms, but this patient had no subjective respiratory symptoms and had no abnormalities in respiratory rate and oxyhaemoglobin saturation. Although very rare, we do believe that this clinical course will provide some suggestive information on treatment for patients with similar course in the future.

INTRODUCTION
Limited data exist regarding the prevalence and clinical practice involving generic drugs and biosimilars for treating ulcerative colitis (UC) in Japan. We aimed to clarify the clinical usage of these generic drugs and biosimilars for UC treatment in Japan using a nationwide database.
METHODS
We collected data from 30,675 UC cases, along with their prescriptions for both generic drugs or biosimilars and their original counterparts, using a medical claim database provided by DeSC Healthcare, Inc. We calculated the prescription and penetration rates of generic drugs and biosimilars and demonstrated the transition of these rates. Additionally, the cumulative retention rates between infliximab originator and biosimilar were compared using the Kaplan-Meier method.
RESULTS
The prescription rate of generic mesalazine increased from approximately 10% in 2015 to over 30% in 2021. Although the prescription rate of generic molecular targeting drugs (MTDs) also increased from approximately 0.15% in 2014 to 2.5% in 2021, the increment was lower than that of generic mesalazine. The penetration rates of generic 5-aminosalicylic acid and tacrolimus ranged from over 30% to approximately 50%. Infliximab biosimilar achieved an approximate 20% penetration rate, whereas adalimumab achieved <5%. The cumulative retention rates did not differ between infliximab originator and biosimilar.
CONCLUSIONS
The penetration rates of generics and biosimilars for UC treatment are relatively low compared with those for treatment in other fields and the goal of the Ministry of Health, Labor, and Welfare. Several countermeasures are necessary for the widespread use of generics and biosimilars, ultimately contributing to cost-effective and sustainable healthcare delivery.
