BMJ case reports 15 ( 7 ) 2022.07 [International journal]

A man in his 80s who had a history of diabetes mellitus and aortic valve replacement was referred to our hospital for treatment of early gastric cancer and underwent endoscopic submucosal dissection (ESD). Three days after ESD, the patient presented with low back pain and fever (38.7°). We initially considered adverse events associated with gastric ESD such as delayed perforation. Moreover, thromboembolism and infectious endocarditis were suspected because of his medical history. However, there were no remarkable findings suggestive of these diseases. Finally, based on the results of blood cultures and MRI, the diagnosis of pyogenic spondylitis (PS) was made. We administered antibiotics for 12 weeks, and the patient improved without neurological impairments. This case indicates that bacteraemia and subsequent PS can occur following gastric ESD. Physicians should not overlook the patient's physical signs related to various adverse events after ESD.

Immunotherapy using anti-programmed death 1 ligand 1 (PD-L1) antibodies has shown clinical efficacy against hepatocellular carcinoma (HCC) and is recognized as the first-line treatment for unresectable HCC. PD-L1 expression is affected by various cytokines produced by immune cells in the tumor microenvironment; however, there is limited information about the effects of cytokine interactions on PD-L1 expression. In this study, we examined how cytokines induce PD-L1 expression in HCC cells. Both interferon gamma (IFN-γ) and interleukin 1 beta (IL-1β) induced PD-L1 expression, and the two cytokines enhanced PD-L1 expression in combination compared to that when administered alone. The Janus kinase/signal transducer and activator of transcription signaling pathway activated by IFN-γ is the major pathway of PD-L1 expression. The increase in interferon regulatory factor 1 expression and IFN-γ receptor expression induced by IL-1β was associated with the synergistic effect of IFN-γ and IL-1β on PD-L1 expression. These findings strongly indicate that IFN-γ and IL-1β affect the mechanism underlying immune resistance in HCC cells.

BACKGROUND: Noninvasive biomarkers of intestinal inflammation can reduce the number of endoscopies in children with inflammatory bowel disease (IBD). This study aimed to prospectively investigate the usefulness of fecal calprotectin (FCP) and fecal immunochemical test (FIT) in pediatric IBD. METHODS: Patients aged 6-17 years who underwent ileocolonoscopy for established or suspected IBD were eligible for this study. Fecal samples for FCP and FIT were collected before colonoscopy. RESULTS: A total of 251 samples were analyzed: 88 from ulcerative colitis (UC), 74 from Crohn's disease (CD), 75 from healthy controls (HC), and 14 from children with functional gastrointestinal disorders and normal colonoscopy (NC). At IBD diagnosis, both FCP and FIT were significantly higher in the newly diagnosed UC/CD group than in the HC/NC group (P < 0.001). The optimal cutoffs of FCP and FIT to predict IBD diagnosis were 217 mg/kg and 87 ng/mL, respectively. Patients without mucosal healing (MH) showed higher FCP and FIT than those with MH in both UC and CD (P < 0.001). The FCP increased exponentially as the endoscopic activity score increased. The optimal cutoff values of FCP and FIT for predicting MH were 161 mg/kg and 106 ng/mL for UC and 367 mg/kg and 57 ng/mL for CD, respectively. FCP showed better specificity than the FIT. Patients with CD and normal ileocolonoscopy had elevated FCP during active small intestinal inflammation. CONCLUSIONS: Both FCP and FIT correlate well with endoscopic activity in pediatric patients with IBD. The FCP is a superior marker for predicting MH.

Introduction: The use of a simple diagnostic system for nonalcoholic fatty liver disease (NAFLD) instead of a biopsy is expected. We investigated a positive pattern recognition system for the evaluation of nonalcoholic fatty liver (NAFL) and the stages of nonalcoholic steatohepatitis (NASH). Methods: A total of 68 Japanese patients with biopsy-confirmed NAFLD were enrolled. Serological biomarkers and medical imaging markers were investigated to determine candidate markers. The markers were statistically evaluated, and the patients were distributed to pattern combinations. Results: We selected three markers based on natural history and set the critical values: alanine aminotransferase/ALT (persistent ≧ 44 IU/L) as a marker for hepatitis, type IV collagen 7S (≧5.1 ng/mL) for fibrosis, and E value (≧5.5 kPa) for stiffness. After evaluation of statistical accuracies, every patient was classified into their combination patterns. Comparing the relationships between histological classifications and positive patterns, the patients with NAFL were mainly distributed in pattern (ALT, type IV collagen, E value: -, -, -), those with NASH stage 0-1 in (+, -, +), those with NASH stage 2-3 in (+, +, +), and those with NASH stage 4 in (-, +, +). Conclusions: The positive patters changed with the NAFL and NASH conditions. Our results indicated a correlation between the positive patterns using three markers and the histological results. The positive pattern recognition system based on natural history is useful for the differential diagnosis of NAFLD and for the evaluation of the severity of fibrosis in patients with NASH.

BACKGROUND: The spread of coronavirus disease 2019 (COVID-19) had a major impact on the health of people worldwide. The clinical background and clinical course of inflammatory bowel disease (IBD) among Japanese patients with COVID-19 remains unclear. METHODS: This study is an observational cohort of Japanese IBD patients diagnosed with COVID-19. Data on age, sex, IBD (classification, treatment, and activity), COVID-19 symptoms and severity, and treatment of COVID-19 were analyzed. RESULTS: From 72 participating facilities in Japan, 187 patients were registered from June 2020 to October 2021. The estimated incidence of COVID19 in Japanese IBD patients was 0.61%. The majority of IBD patients with COVID-19 (73%) were in clinical remission. According to the WHO classification regarding COVID-19 severity, 93% (172/184) of IBD patients had non-severe episodes, while 7% (12/184) were severe cases including serious conditions. 90.9% (165/187) of IBD patients with COVID-19 had no change in IBD disease activity. A logistic regression analysis stepwise method revealed that older age, higher body mass index (BMI), and steroid use were independent risk factors for COVID-19 severity. Six of nine patients who had COVID-19 after vaccination were receiving anti-tumor necrosis factor (TNF)-α antibodies. CONCLUSION: Age, BMI and steroid use were associated with COVID-19 severity in Japanese IBD patients.
