To compare the efficacy and safety of gecacitinib (also known as jaktinib) with hydroxyurea (HU) in treating myelofibrosis (MF) patients. In this multicenter, randomized phase 3 trial (ZGJAK016), intermediate- or high-risk primarily JAK inhibitor naïve MF patients were assigned in a 2:1 ratio to receive either gecacitinib (100 mg twice a day, BID) or HU (500 mg BID). The primary endpoint was the proportion of patients with ≥35% reduction in spleen volume (SVR35) from baseline at week 24.

Severe hypophosphataemia and hypocalcaemia following intravenous ferric derisomaltose and denosumab administration.

Serum calcium and phosphorus levels are tightly regulated by the calciotropic hormone parathyroid hormone, fibroblast growth factor 23 and 1,25(OH) vitamin D. Commonly prescribed therapies for iron-deficiency anaemia (IDA) such as ferric carboxymaltose and ferric derisomaltose (FDM) have been shown to disrupt phosphorus homeostasis, resulting in hypophosphataemia. Similarly, denosumab use can result in hypocalcaemia due to the inhibition of osteoclastic maturation, activity and survival.

Successful rituximab treatment in a seronegative rheumatoid arthritis patient with concurrent cold agglutinin syndrome and immune thrombocytopenia.

Cold agglutinin disease, a subtype of cold-type autoimmune hemolytic anemia, is referred to as cold agglutinin syndrome (CAS) when it develops secondary to other conditions. Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by the peripheral destruction of platelets. While both CAS and ITP can occur in patients with rheumatoid arthritis (RA), their concurrent manifestation in a single patient has not been reported, leaving the optimal treatment strategy for such a complex case unclear.
