1. 11. Colonization, infection and dissemination in intensive care patients

   Författare :Christina Agvald-Öhman; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Colonization; multi-resistant bacteria; dissemination; intensive care unit; invasive Candida infection;

   Sammanfattning : Nosocomial infections are a substantial problem in hospitals all over the world and the incidence is among the highest in the intensive care unit, affecting mortality and morbidity for the individual patient and cost for the society. In order to prevent these infections it is important to gain knowledge about colonization and infection pathways as well as about bacterial dissemination between patients. LÄS MER

3. 12. Immune modulation in chronic HBV and HCV infection

   Författare :Catharina Hultgren; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :HBV; HBeAg; HCV; NS3; chronic infection; humoral cellular immune response; Th1 Th2 cells; proliferative response;

   Sammanfattning : Chronic viral hepatitis is a major health problem worldwide. The two major viral causes for chronic hepatitis are the hepatitis B (HBV) and C viruses (HCV). HBV is a DNA virus with a rather limited genetic variability whereas HCV is an RNA virus with a high genetic variability. LÄS MER

   Sammanfattning : Aims: The aims of the study were to establish and evaluate the best eradication treatment, the optimal diagnostic methods and the impact of Helicobacter pylori infection in Vietnam. Materials: In a treatment trial of patients with peptic ulcer disease (PUD), gastric biopsies and serum samples were obtained from 296 PUD patients (age 18-88 years). LÄS MER

5. 14. Markers of Infection in Childhood Autoimmune Diabetes and Related Disorders

   Författare :Anna-Lena Nilsson; Celiaki och diabetes; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autoimmune type 1 diabetes Ljungan virus antibodies Islet autoantibodies HLA;

   Sammanfattning : The main aim of this thesis was to contribute to the knowledge about mechanisms involved in the development of type 1 diabetes (T1D) and other autoimmune diseases in children. Immune markers in relation to genetic propensity in children with autoimmune disease, mainly T1D and a small group of juvenile idiopathic arthritis (JIA) and thyroiditis (THYR), as well as healthy controls have been studied.

7. 15. HIV-1 immune responses induced by natural infection or immunisation

   Författare :Lindvi Gudmundsdotter; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The development of an effective HIV-1 vaccine must be considered as one of today s greatest biomedical goals and challenges. The nature of the HIV-1 virus, characterised by its tropism for the CD4+ T cells of the immune system and its integration into the host genome, together with the vast viral variability, allows the HIV-1 virus to establish a latent infection and evade the host defence mechanisms.
