Hairy cell leukemia is an uncommon hematological malignancy characterized by an accumulation of abnormal B lymphocytes. It is usually classified as a subtype of chronic lymphocytic leukemia (CLL). Hairy cell leukemia makes up about 2% of all leukemias, with fewer than 2,000 new cases diagnosed annually in North America and Western Europe combined. Hairy cell leukemia (HCL) was originally described as histiocytic leukemia, malignant reticulosis, or lymphoid myelofibrosis in publications dating back to the 1920s. The disease was formally named leukemic reticuloendotheliosis, and its characterization was significantly advanced by Bertha Bouroncle and colleagues at the Ohio State University College of Medicine in 1958. Its common name, which was coined in 1966, is derived from the "hairy" appearance of the malignant B cells under a microscope. Signs and symptoms
In HCL, the "hairy cells" (malignant B lymphocytes) accumulate in the bone marrow, interfering with the production of normal white blood cells, red blood cells, and platelets. Consequently, patients may develop infections related to low white blood cell count, anemia and fatigue due to a lack of red blood cells, or easy bleeding due to a low platelet count.
Senna glycoside, also known as sennoside or senna, is a medication used to treat constipation and empty the large intestine before surgery. The medication is taken by mouth or via the rectum. It typically begins working in around 30 minutes when given by rectum and within twelve hours when given by mouth. It is a weaker laxative than bisacodyl or castor oil.Common side effects of senna glycoside include abdominal cramps. It is not recommended for long-term use, as it may result in poor bowel function or electrolyte problems. While no harm has been found to result from use while breastfeeding, such use is not typically recommended. It is not typically recommended in children. Senna may change urine to a somewhat reddish color. Senna derivatives are a type of stimulant laxative and are of the anthraquinone type. While its mechanism of action is not entirely clear, senna is thought to act by increasing fluid secretion within and contraction of the large intestine.It is on the World Health Organizations List of Essential Medicines. It is available as a generic medication. Sennosides come from the group of plants Senna. In plant form, it has been used at least since the 700s CE. In 2019, it was the 344th most commonly prescribed medication in the United States, with fewer than one million prescriptions. It is sold under a number of brand names including Ex-Lax and Senokot.
