For Inflammatory Bowel Disease
250 NATIONAL INSTITUTE FOR CLINICAL EXCELLENCE INTERVENTIONAL PROCEDURES PROGRAMME Interventional procedures overview of leukapheresis (white cell apheresis) for inflammatory bowel disease Introduction This overview has been prepared to assist members of the Interventional Procedures Advisory Committee (IPAC) in making recommendations about the safety and efficacy of an interventional procedure. It is based on a rapid review of the medical literature and specialist opinion. It should not be regarded as a definitive assessment of the procedure. Date prepared This overview was prepared in August 2004. Procedure names • Leukapheresis • White cell apheresis. • Leukocyte removal therapy. • Selective granulocyte and monocyte adsorption apheresis. • Leukocytapheresis. Specialty society • British Society of Gastroenterology. Description Indications Inflammatory bowel disease. Ulcerative colitis and Crohn’s disease are the most common forms of inflammatory bowel disease. Ulcerative colitis causes inflammation and ulceration of the rectum and sometimes the colon. Symptoms include bloody diarrhoea and rectal bleeding. Crohn’s disease usually causes inflammation and ulceration of the small and large intestines, but it can affect any part of the digestive tract. The main symptoms are abdominal pain, diarrhoea and weight loss. Both of these are chronic conditions, characterised by periods of clinical relapse and remission. The incidence of ulcerative colitis is around 10 to 20 per 100,000 per year in the UK and the incidence of Crohn’s disease is approximately 5 to 10 per 100,000 per year.1 Current treatment and alternatives Conservative treatments include dietary measures, and medications to control inflammation. Immunosuppressants may be used if other medical therapies are ineffective at maintaining remission. Patients with ulcerative colitis that does not respond to medical therapy may be treated with surgery to remove the colon. -

Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease Bone Marrow (Stem Cell) Transplant
Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease Bone Marrow (Stem Cell) Transplant for Sickle Cell Disease 1 Produced by St. Jude Children’s Research Hospital Departments of Hematology, Patient Education, and Biomedical Communications. Funds were provided by St. Jude Children’s Research Hospital, ALSAC, and a grant from the Plough Foundation. This document is not intended to take the place of the care and attention of your personal physician. Our goal is to promote active participation in your care and treatment by providing information and education. Questions about individual health concerns or specifi c treatment options should be discussed with your physician. For more general information on sickle cell disease, please visit our Web site at www.stjude.org/sicklecell. Copyright © 2009 St. Jude Children’s Research Hospital How did bone marrow (stem cell) transplants begin for children with sickle cell disease? Bone marrow (stem cell) transplants have been used for the treatment and cure of a variety of cancers, immune system diseases, and blood diseases for many years. Doctors in the United States and other countries have developed studies to treat children who have severe sickle cell disease with bone marrow (stem cell) transplants. How does a bone marrow (stem cell) transplant work? 2 In a person with sickle cell disease, the bone marrow produces red blood cells that contain hemoglobin S. This leads to the complications of sickle cell disease. • To prepare for a bone marrow (stem cell) transplant, strong medicines, called chemotherapy, are used to weaken or destroy the patient’s own bone marrow, stem cells, and infection fi ghting system. -

Baiocchi3, Thomas A. Mace1 and William E. Carson III1,2* Abstract Background: Tumor-associated macrophages (TAM) are expanded and exhibit tumor-promoting properties within the tumor microenvironment. Current methods to study TAM have not been replicated across cancer types and often do not include exogenous growth factors from the tumor, a key factor in TAM differentiation in vivo. Methods: In this study, an in vitro method to generate monocyte- derived TAM using tumor- conditioned media (TCM) and a cytokine cocktail containing IL-4, IL-10, and M-CSF was utilized to study the phenotype, morphology, and function of TAM across multiple cancer types. TCM was generated from two breast cancer cell lines and an Epstein-Barr virus-positive lymphoma cell line. The properties of in vitro generated TAM were compared to in vitro generated M1 and M2- like macrophages and TAM isolated from patients with cancer. Results: TAM generated in this fashion displayed an increase in CD163/CD206 co-expression compared to M2- like http://jitc.bmj.com/ macrophages (87 and 36%, respectively). -
Myelodysplastic Syndromes Overview and Types
cancer.org | 1.800.227.2345 About Myelodysplastic Syndromes Overview and Types If you have been diagnosed with a myelodysplastic syndrome or are worried about it, you likely have a lot of questions. Learning some basics is a good place to start. ● What Are Myelodysplastic Syndromes? ● Types of Myelodysplastic Syndromes Research and Statistics See the latest estimates for new cases of myelodysplastic syndromes in the US and what research is currently being done. ● Key Statistics for Myelodysplastic Syndromes ● What's New in Myelodysplastic Syndrome Research? What Are Myelodysplastic Syndromes? Myelodysplastic syndromes (MDS) are conditions that can occur when the blood- forming cells in the bone marrow become abnormal. This leads to low numbers of one or more types of blood cells. MDS is considered a type of cancer1. Normal bone marrow 1 ____________________________________________________________________________________American Cancer Society cancer.org | 1.800.227.2345 Bone marrow is found in the middle of certain bones. It is made up of blood-forming cells, fat cells, and supporting tissues. A small fraction of the blood-forming cells are blood stem cells. Stem cells are needed to make new blood cells. There are 3 main types of blood cells: red blood cells, white blood cells, and platelets. Red blood cells pick up oxygen in the lungs and carry it to the rest of the body. These cells also bring carbon dioxide back to the lungs. Having too few red blood cells is called anemia. It can make a person feel tired and weak and look pale. Severe anemia can cause shortness of breath. White blood cells (also known as leukocytes) are important in defending the body against infection. -

LECTURE 05 Acquired Immunity and Clonal Selection
LECTURE: 05 Title: ACQUIRED "ADAPTIVE" IMMUNITY & CLONAL SELECTION THEROY LEARNING OBJECTIVES: The student should be able to: • Recognize that, acquired or adaptive immunity is a specific immunity. • Explain the mechanism of development of the specific immunity. • Enumerate the components of the specific immunity such as A. Primary immune response. B. Secondary immune response • Explain the different phases that are included in the primary and secondary immune responses such as: A. The induction phase. B. Exponential phase. C. Steady phase. D. Decline phase. • Compare between the phases of the primary and secondary immune responses. • Determine the type of the immunoglobulins involved in each phase. • Determine which immunoglobulin is induced first and, that last longer. • Enumerate the characteristics of the specific immunity such as: A. The ability to distinguish self from non-self. B. Specificity. C. Immunological memory. • Explain naturally and artificially acquired immunity (passive, and active). • Explain the two interrelated and independent mechanisms of the specific immune response such as : A. Humoral immunity. B. Cell-mediated (cellular) immunity. • Recognize that, the specific immunity is not always protective, for example; sometimes it causes allergies (hay fever), or it may be directed against one of the body’s own constituents, resulting in autoimmunity (thyroditis).
