l-Glutamine for sickle cell anemia: more questions than answers
1Division of Hematology, Cincinnati Children's Hospital Medical Center, Cincinnati, OH.
Abstract:
In 2017, the Food and Drug Administration approved 2 medications for sickle cell anemia (SCA): hydroxyurea for children and l-glutamine for children and adults. The approval of hydroxyurea was long overdue, but the approval of l-glutamine was a surprise to many. Any effective new treatment for SCA is a welcome advance, but there are few published studies of l-glutamine as a specific treatment for SCA. Accordingly, there are many unanswered questions about its efficacy, safety, and role in current therapy.

Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...
