Objectives: To investigate the association between Kaposi's sarcoma-associated immune reconstitution inflammatory syndrome (KS-IRIS) and mortality, with the use of glucocorticoids in HIV-infected individuals.
Design: Case-control study.
Methods: We reviewed the medical records of 145 individuals with HIV-associated Kaposi's sarcoma receiving antiretroviral therapy. The association of different variables with KS-IRIS and Kaposi's sarcoma-related mortality was explored by univariate and multivariate analyses. The main exposure of interest was the use of glucocorticoids. We also compared the time to KS-IRIS and the time to death of individuals treated with glucocorticoids vs. those nontreated with glucocorticoids, and the time to death of individuals with KS-IRIS vs. those without KS-IRIS by hazards regression.
Results: Sixty of 145 individuals received glucocorticoids (41.4%) for the management or suspicion of Pneumocystis jirovecii pneumonia. Fifty individuals had KS-IRIS (37%). The use of glucocorticoids was more frequent in individuals with KS-IRIS than in those without KS-IRIS (54.9 vs. 36.47%, P = 0.047). Kaposi's sarcoma-related mortality occurred in 17 cases (11.7%), and glucocorticoid use was more frequent in this group (76.47 vs. 36.7%, P = 0.003). Glucocorticoid use was a risk factor for mortality (adjusted odds ratio = 4.719, 95% confidence interval = 1.383-16.103, P = 0.0132), and was associated with shorter periods to KS-IRIS (P = 0.03) and death (P = 0.0073). KS-IRIS was a risk factor for mortality (P = 0.049).
Conclusion: In HIV-infected individuals, the use of glucocorticoids is a risk factor for KS-IRIS and Kaposi's sarcoma-associated mortality. In addition, KS-IRIS is a risk factor for mortality. Therefore, glucocorticoid administration in this population requires careful consideration based on individualized risk-benefit analysis.

Background: Lynch syndrome (LS), an autosomal dominant disorder resulting from germline pathogenic variants in DNA mismatch repair genes, poses an elevated risk of developing different types of cancer, particularly colorectal and endometrial. Early identification of LS individuals is vital for implementing preventive measures. This study aims to assess the adherence rate of LS individuals to colorectal surveillance and identify influencing factors.

Ventricular assist device (VAD) and cardiac transplant patients experience significant strain on their physical and mental wellbeing postoperatively. Mental health and substance use disorders (MHDs and SUDs) have substantial effects on the quality of life and compliance of transplant and VAD patients. In this study, we compare and characterize MHDs and SUDs between VAD and cardiac allograft patients and transplant list patients with and without VADs.

Aims: Doctors have an increased risk of SARS-CoV-2 infection caused by exposure to contagious patients. We aimed to identify which clinical specialities among medical doctors had the highest occupation-related risk of testing positive for SARS-CoV-2, utilizing data for all publicly employed medical doctors in Sweden.
Methods: Data regarding positive SARS-CoV-2 test results and employment for publicly employed doctors in Sweden were divided into three observation periods: 1) 1 February to 31 December 2020, 2) 1 January to 30 June 2021 and 3) 1 July 2021 to 31 March 2022.
Immune checkpoint inhibitor-associated diabetic ketoacidosis and insulin-dependent diabetes: a case report.
J Med Case Rep
December 2024
Emergency Medicine, Vancouver General Hospital, Vancouver, Canada.
Background: Immunotherapy, including the use of immune checkpoint inhibitors such as nivolumab, is increasingly common in cancer treatment and can lead to various immune-related adverse effects, including rare cases of diabetic ketoacidosis. This case report highlights an unique instance of nivolumab-induced diabetic ketoacidosis in a patient without prior history of diabetes, emphasizing the importance of careful monitoring even in those without traditional risk factors.
Case Presentation: We report a case of a 70-year-old Caucasian male with metastatic esophageal adenocarcinoma who developed diabetic ketoacidosis 3 weeks after stopping nivolumab therapy.
