Janus kinase (JAK) inhibitors have heralded a paradigm shift in the management of immune-mediated diseases. While their efficacy is well-established, the safety concerns associated with these agents, particularly regarding thromboembolic events (TE), remain a focus of extensive research and clinical scrutiny. This comprehensive literature review embarks on an exploration of the multifaceted landscape of JAK inhibitors, providing insights into their safety profiles across diverse immune-mediated diseases. The introduction highlights the transformative influence of JAK inhibitors in the treatment of immune-mediated diseases. Historically, the therapeutic arsenal for these conditions included corticosteroids, disease-modifying antirheumatic drugs (DMARDs), and biologics. The advent of JAK inhibitors has revolutionized this landscape, although concerns about their safety persist. This review strives to comprehensively evaluate their safety, amalgamating knowledge from multiple studies and trials. The subsequent sections delve into the safety of specific JAK inhibitors in the context of rheumatoid arthritis, inflammatory bowel diseases, and dermatologic conditions and their associations with venous thromboembolism. The evolving understanding of TE risk, particularly the intricate relationship between these agents and immune-mediated diseases, is meticulously unravelled. The concluding remarks underscore the dynamic nature of TE risk assessment with regard to immune-mediated diseases involving JAK inhibitors. It underscores that risk assessment is multifactorial, influenced not only by the choice of JAK inhibitor but also by the nuances of the underlying immune-mediated disease and the unique patient characteristics. This review offers a holistic perspective on TE risks associated with JAK inhibitors and contributes to the ongoing dialogue regarding their safety in the realm of immune-mediated diseases.

Introduction: Benign prostatic hyperplasia (BPH) is a histological diagnosis characterized by an increase in the number of epithelial and stromal cells in the transitional zone of the prostate gland. The clinical manifestation of BPH is associated with the appearance of so-called lower urinary tract symptoms (LUTS) which can also be a consequence of other conditions not related to the prostate. Covid-19, also known as severe acute respiratory syndrome coronavirus 2 was discovered as a disease in late 2019 in the city of Wuhan, China. Materials and Methods: A case-control study was conducted between September 2021 and May 2022. Information was initially collected on 60 patients followed up and treated conservatively for BPH in two outpatient practices and recovered from Covid-19. After processing the received information, 27 patients were excluded from the study and 33 patients remained for observation The assessment of patients is carried out through an internationally validated questionnaire – international prostate symptom score (IPPS), prostate specific antigen, digital rectal examination (DRЕ), and ultrasound diagnostics of the prostate gland with consideration of its volume and the amount of residual urine. Results: Our data show a strong correlation between the changes in LUTS in patients with BPH and Covid-19 infection. Conclusion: Although almost 3 years have passed since the beginning of this pandemic, there are still many unanswered questions surrounding this disease. We believe that with our experience we will enrich the information about the relationship between Covid-19 and LUTS, and the results obtained by us can serve as a basis for future large-scale and more in-depth studies on the subject.

Cases of adenocarcinoma of the bladder are extremely low - 2%, respectively. Primary signet-ring cell carcinoma (SRCC) of the bladder accounts for 0.12–0.6% among the different histological subtypes of bladder carcinomas.

Primary malignant melanoma of the female urethra is an extremely rare disease. Its frequency is only 0.2% of all malignant melanomas. This type of carcinoma is associated with a poor prognosis and short survival due to the early occurrence of metastases and delayed diagnosis. We present a patient with primary malignant melanoma invading the distal urethra, part of the labia minora, and sections of the anterior vaginal wall, where 15 months of overall survival were achieved against the background of the complex treatment.
