Article Synopsis
  • - The study examined the impact of the HLADQA1*05 gene on patients with inflammatory bowel disease receiving first-line anti-TNF therapies (adalimumab or infliximab) from 2000 to 2021, focusing on response rates, loss of response (LOR), and adverse events (AE).
  • - Out of 408 patients, HLADQA1*05 was linked to a significant increase in the risk of LOR and immunogenicity, especially related to infliximab, while HLADQA1*03 appeared to protect against LOR when using adalimumab.
  • - The findings suggest that genetic factors like HLADQA1*05 and sex play crucial roles in treatment

Natural products (NPs) are secondary metabolites of natural origin with broad applications across various human activities, particularly the discovery of bioactive compounds. Structural elucidation of new NPs entails significant cost and effort. On the other hand, the dereplication of known compounds is crucial for the early exclusion of irrelevant compounds in contemporary pharmaceutical research.

The role of the inflammasomes in aging and progeroid syndromes remain understudied. Recently, MCC950, a NLRP3 inhibitor, was used in Zmpste24 mice to ameliorate the phenotypes. However, the safety of MCC950 was questioned due to liver toxicity observed in humans.

Merkel cell carcinoma is a very aggressive primary skin tumour with a high risk of local recurrences and lymphatic and distant metastases. The frequent association between this carcinoma and other skin tumour and lymphoid malignancies, its similar cellular morphology with leukocytes, and limited infiltration in bone marrow constituted a challenging diagnosis. We report an unusual case of an 82-year-old male who simultaneously presented Merkel cell carcinoma and acute myeloid lymphoma.
