A few years later, she noticed a round lesion on her left buttock. Since the lesion had been asymptomatic and never grown, more than 20 years had passed before she saw a local doctor to consult about it. Although the lesion was suspected to be tinea corporis, no fungi were found on microscopic examination. Subsequently, administered topical corticosteroids were not effective. She was referred to our hospital for further evaluation, and a skin biopsy confirmed the diagnosis of porokeratosis. There was a possibility that chemotherapy, total body radiation, or immunosuppressive therapy associated with allogeneic bone marrow transplantation was involved in the development of porokeratosis. Numerous cases of acquired porokeratosis in immunocompromised status have been observed; as for those after allogenic bone marrow transplantation, 12 cases have been reported in the English literature, 4 of which had only one or a few lesions on a limited area of body surface. Our case was relatively uncommon in that the lesion was solitary and comparatively large. In a localized type of porokeratosis, it was suggested that a malignant skin tumor developed earlier than in other types. Careful follow-up for malignant transformation is especially required.","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129996265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gastrointestinal (GI) events are among the most frequent irAEs and the hallmark symptom is diarrhea. Intestinal hypomotility as irAEs is exceedingly rare, and needs wider recognition given that the presentation is insidious.Here, we report a case of 79-year-old woman with metastatic melanoma under nivolumab and ipilimumab combination therapy. She developed ileus symptom, and was diagnosed with acute colonic pseudo-obstruction. The symptom relieved soon after administering high-dose prednisolone five days after the onset. ICI therapy was discontinued.Intestinal hypomotility as GI irAEs is exceedingly rare and there have been five reported cases to our knowledge. In reviewing past cases, we speculate that the prompt initiation of corticosteroids resulted in a favorable outcome. Our case illustrates that early recognition of these rare irAEs is essential in order to ensure prompt treatment.","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129667006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The selected 96 healthy adult SD rats were randomly divided into the experimental group and control group; 48 in each group. Each group was randomly subdivided into 6 groups with 8 rats in each group. The superior mesenteric artery was ligated in the experimental group and the peritoneal switch operation was performed in the control group. The venous blood samples were extracted from each group rats’ right ventricle at 0.5 h, 1 h, 2 h, 4 h, 8 h, 12 h after the operation and the concentration of I-FABP was tested respectively. Then the rats were killed, and the diseased intestinal tubes were cut out for paraffin sections. The I-FABP in intestinal tissue was stained by routine HE staining and direct immunofluorescence staining. Results: The I-FABP was mainly expressed in the epithelial villi of intestinal mucosa, and there was a small amount of expression in the intestinal submucosa and even the muscularis. Within 1 hour of intestinal ischemia, the number of I-FABP positive granules in the intestine and intestinal cavity increased gradually, and then gradually decreased after 1 hour. The difference has statistically significant between the experimental group and the control group (P < 0.05). The serum I-FABP: In the experimental group, the serum I-FABP concentration began to increase at 0.5 h, and reached a peak at 1 h (290. 24 ± 156.69) μg·L–1, then gradually decreased. Compared with the control group, the difference was statistically significant (P < 0.05). Conclusion: I-FABP usually mainly exists in the epithelial cells of intestinal mucosa. When acute intestinal ischemia occurs, the epithelial cells of intestinal mucosa permeability changes; I-FABP expression rapidly releases to intestinal tissue and intestinal cavity, and is absorbed into the blood. Therefore, I-FABP has certain clinical significance in early diagnosis and treatment of acute intestinal ischemia.","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133309369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: NCI-H460 cells were implanted into nude mice and the transplantation tumor block from nude mice of more than 2 generations was inoculated to the right armpits of BALB/c mice with dissecting needle to establish a lung cancer xenograft model. When the transplanted volume was about 50 mm3, the mice were randomly divided into 6 groups: (1) model group; (2) 10 mg·kg–1 cisplatin group; (3) 10 mg·kg–1 PDTC group; (4) TUA high dose group (30 mg·kg–1); (5) TUA middle dose group (12 mg·kg–1); (6) TUA low dose group (6 mg·kg–1). Administration approach was intratumoral injection. The effects of each group on the weight of transplanted tumor animals, the volume and weight of tumor were continuously observed for 14 days. Tumor volume growth curve was drawn and tumor inhibitory rate and index were calculated; HE staining was used to observe nude mice tumor tissue pathological changes. The effects of TUA on NF-κB signaling pathway related proteins were detected by immunohistochemistry and Western blot. Results: In vivo experiments showed that the transplanted tumors in nude mice became smaller compared with the models. With the increase of TUA dose, the tumor tissue became smaller and smaller, especially in high TUA dose (30 mg·kg–1). It had the similar size with the NF-κB inhibitor PDTC (10 mg·kg–1) group. HE dyeing observation results confirmed the degree of tumor necrosis and fission in TUA treated tumor tissues obviously decreased. Immunohistochemical results showed that comparing the TUA treatment group with the model group, p65 expression in tumor tissues was reduced, and expression of IκBα increased. Western blot results also showed that the NF-κB related p65 protein expression levels decreased, at the same time IκBα protein expression level increased; the apoptosis related proteins Survivin protein expression was depressed, Caspase-3 protein expression was promoted. Conclusion: TUA significantly inhibits the growth of lung transplantation tumor and its mechanism. It may be related to the decreasing the expression of p65, Survivin and increasing the expression of IκBα, Caspase-3 in tumor tissues.","PeriodicalId":401129,"journal":{"name":"Trends in Immunotherapy","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117062787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
