Background/Objectives: Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease caused by an autoimmune attack on hepatocytes. The first-line treatment for AIH comprises two core components: glucocorticoids and thiopurine analog inhibitors and mycophenolate mofetil (MMF). Numerous studies have suggested an increased risk for lymphoma among patients with either rheumatoid arthritis or inflammatory bowel disease (IBD) who are treated with azathioprine/6-mercaptopurine (6-MP). The relative risk of non-Hodgkin lymphoma (NHL) among autoimmune hepatitis patients treated with these immunosuppressive drugs remains unclear. We aimed at investigating the risk of NHL across a large retrospective AIH cohort after a long-term follow-up. Methods: This retrospective, population-based study comprised approximately 2.7 million adults over two decades. It included adult patients aged 20 years or older at the time of autoimmune hepatitis diagnosis who had initiated treatment with azathioprine, 6-MP, or MMF. The primary outcome was the development of non-Hodgkin lymphoma. Results: The study initially included 834 patients diagnosed with AIH. A total of 685 patients remained in the research cohort after matching the data to the local cancer registry. Compared to the predicted NHL rate in the general population, NHL incidence was considerably higher in AIH patients (Standardized Incidence Ratio, SIR = 36.5). Subgroup studies showed that lymphoma mainly affected patients 45 years of age and over and was detected primarily during the first seven years following the AIH diagnosis. No correlation was found between the incidence of NHL and the treatment drug used. Conclusions: Patients with AIH exhibit a markedly higher risk of NHL compared to the general population.

One of the main groups of lipids is phospholipids, which are mainly involved in forming cell membranes. Neoplastic processes such as cell replication have increased lipid synthesis, making tumor cells dependent on this synthesis to maintain their requirements. Antiphospholipid antibodies attack phospholipids in the cell membranes. Three main types of antiphospholipid antibodies are recognized: anti-β2 glycoprotein I (anti-β2GP-I), anticardiolipin (aCL), and lupus anticoagulant (LA). These types of antibodies have been proven to be present in hematological neoplasms, particularly in LH and NHL. This review on antiphospholipid antibodies in hematological neoplasms describes their clinical relationship as future implications at the prognostic level for survival and even treatment.

The presented research focuses on the commonly used Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which is applied to an evaluation of a basic set of 581 national hockey league (NHL) players in the 2018/2019 season. This is used in combination with a number of objective methods for weighting indicators for identifying differences in their usage. A total of 11 indicators with their own testimonial values, including points, hits, blocked shots and more, are selected for this purpose. The selection of a method for weighting indicators has a major influence on the results obtained and the differences between them, and maintains the internal links within the ranked set of players. Of the evaluated methods, we prefer the Mean Weight method, and we recommend that the input indicators be considered equivalent when evaluating athletes. Full article
