ABSTRACT
Trimethoprim-sulfamethoxazole (TMP-SMX) acute respiratory distress syndrome (ARDS) is a rare, but severe complication of a commonly prescribed antibiotic. TMP-SMX typically affects young, otherwise well patients with a specific human leukocyte antigen type (HLA-B*07:02 and HLA-C*07:02). The condition is poorly understood with a unique pathological appearance and mechanism that remains unclear. Mortality rate is greater than one third. We describe the case of a previously well 18-year-old woman treated with a prolonged course of TMP-SMX for a complex urinary tract infection who developed rapidly progressive respiratory failure requiring prolonged intensive care admission, extra-corporeal membranous oxygenation, and eventual lung transplantation. No targeted treatment exists, further research is required to better understand disease pathogenetic mechanisms and potential therapeutic interventions.
ABSTRACT
Kaposi Sarcoma (KS), a mucocutaneous cancer that most frequently occurs in the context of Acquired Immunodeficiency Syndrome (AIDS) secondary to Human Immunodeficiency Virus (HIV), is a relatively benign condition, acting more as a marker of immunodeficiency than directly causing harm itself. However, it has been known to spread both locally and in a metastatic fashion, with reports of KS affecting almost all organ systems. One of the most rarely reported areas of involvement is the musculoskeletal system, with secondary osseous spread representing an even smaller subset of these. We report a case of biopsy proven disseminated intraosseous KS involving the entire imaged skeleton that occurred with HIV/AIDS, despite maximal treatment and normal imaging 8 months prior.
