We herein report a 56-year-old man with severe hypocalcemia during ruxolitinib therapy for myelofibrosis transitioning from JAK2 mutation-positive polycythemia vera. Blood transfusions were administered every one to two weeks for ruxolitinib-induced anemia. Blood tests revealed hypocalcemia with low TRACP-5b, 25-hydroxyvitamin D (25 (OH) D), and 1,25-dihydroxyvitamin D (1,25 (OH) D) levels within the lower reference range.

We present the case of a 41-year-old man with an anterior mediastinal mass and constellation of clinical symptoms, including dyspnea, pleural effusions, pericardial effusions, renal insufficiency, and pancytopenia. After inconclusive results on several laboratory tests and a nondiagnostic surgical biopsy specimen, a specimen from a second surgical biopsy identified the patient's condition as Castleman disease associated with TAFRO (thrombocytopenia, anasarca, fevers, reticulin myelofibrosis, organomegaly) syndrome. This case highlights the importance of obtaining large tissue biopsy samples, interval follow-up, and acknowledging cognitive biases.

Background And Objectives: The oral, potent, and highly selective activin receptor-like kinase 2 (ALK2) inhibitor zilurgisertib (INCB000928) is in development as a treatment for fibrodysplasia ossificans progressiva (FOP), and for anemia due to myelofibrosis, myelodysplastic syndromes, and multiple myeloma. Saliva is an attractive alternative to blood for drug monitoring and pharmacokinetic analysis, as it is non-invasive to retrieve. This is beneficial for patients, such as those with FOP, for whom blood draws can be challenging due to soft tissue damage susceptibility that can cause progressive heterotopic ossification, and for whom tourniquet time and blood draws must be minimized.
