Immunoglobulin allotypes Gm and Km in hematologic malignancies

Immunoglobulin allotypes of the Gm and Km systems have been compared in patients with various forms of hematologic malignancies and healthy controls of the same ethnographic background. These comparisons found an increased frequency of the haplotype Gm and a decreased frequency of Gm in patients with Hodgkin's disease; a decreased frequency of Gm in diffuse, large-cell lymphoma patients; a decreased frequency of Gm and an increased frequency of Gm in acute myeloid leukemia patients; a decreased frequency of Gm in chronic myeloid leukemia patients, and an increased frequency of the phenotype Km(1+) in chronic lymphocytic leukemia patients. These results support previous suggestions of the involvement of immunoglobulin allotypes in the susceptibility to some forms of human hematologic malignancy

Health-related quality of life in patients with interstitial cystitis/bladder pain syndrome and frequently associated comorbidities

PURPOSE: To estimate the association of chronic non-urologic conditions [i.e., fibromyalgia (FM), chronic fatigue syndrome (CFS), and irritable bowel syndrome (IBS)] with health-related quality of life (HRQOL) in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS: A total of 276 women with established diagnoses of IC/BPS completed a telephone interview which included demographics, self-reported medical conditions, the SF-36 health survey, and the interstitial cystitis symptom index (ICSI). Multivariate linear regression analysis was used to identify correlates of SF-36 physical and mental component summary scores. RESULTS: Mean patient age was 45.1 (SD 15.9) years, and 83 % of the subjects were white. Mean values for the SF-36 Physical Component Score (PCS) and Mental Component Score (MCS) means were 39 (SD 14) and 45 (SD 12), respectively, indicating significant HRQOL reductions. Mean ICSI score was 11.27 (SD = 4.86). FM and IBS were significantly associated with worse SF-36 scores: −8 points on the PCS (p <0.001) and −6 points on the MCS (p <0.001). CFS and the presence of other pelvic conditions (overactive bladder, vulvodynia, endometriosis) were not significantly associated with SF-36 PCS and MCS scores. CONCLUSIONS: In patients with IC/BPS, the presence of FM, CFS, and IBS has a significant association with HRQOL, equivalent in impact to the bladder symptoms themselves. These results emphasize the importance of a multidisciplinary approach to treating patients with IC/BPS and other conditions
