- Objective: The aim was to prospectively measure quality of fife in patients with malignant blood disorders following stem cell transplantation (SCT) using an individualized and a standardized measure. Methods: Twenty-two consecutive patients were assessed before and one year following SCT, using a generic and disease-related version of the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) and the EORTC QLQ-C30. Results of the QLQ-C30 were compared with Swedish norm values. Results: A majority of the patients reported concerns related to health before as well as one year after SCT, recorded by both instruments. Mean scores produced by the SEIQoL-DW, and four scales of the EORTC QLQ-C30, showed a change over time, indicating improved quality of life one year after SCT. In comparison with Swedish norm values for the EORTC QLQ-C30, SCT recipients reported a worse functioning. Conclusions: In addition to well-known disease and treatment-related problems, areas not typically included in standardized instruments were nominated in the disease-related SEIQoL-DW. Such areas included positive aspects, e.g. a changed view of fife and oneself. The results support the use of the generic and disease-related SEIQoL-DW to achieve a comprehensive picture of patient's clinical situation under treatment or when recovering from illness.

- BACKGROUND:Recent studies indicate increased risks of malignant lymphomas among individuals treated with corticosteroids, but have not taken into account the underlying reasons for steroid use, so the increased risks might be attributable to the underlying disease or concomitant treatments other than steroids. Polymyalgia rheumatica (PMR) and temporal arteritis (giant cell arteritis, GCA) are common inflammatory conditions treated with steroids as single immunosuppressive therapy, but data on lymphoma risk in GCA/PMR are limited.OBJECTIVE:To assess the risk of lymphoma associated with steroid treatment of GCA/PMR.METHODS:The association between GCA/PMR and malignant lymphomas (overall, and separately for non-Hodgkin lymphoma, Hodgkin lymphoma, and chronic lymphatic leukaemia) was examined in a nationwide, population based, case-control study of 42,676 lymphoma cases and 78,487 matched population controls, using prospectively recorded data on lymphomas from the Swedish cancer register 1964-2000 and data on pre-lymphoma hospital admissions for GCA/PMR from the Swedish inpatient register 1964-2000. Odds ratios (OR) associated with a pre-lymphoma hospital admission for GCA/PMR were calculated using conditional logistic regression.RESULTS:153 lymphoma cases and 345 population controls had a history of GCA/PMR, resulting in an overall OR for malignant lymphomas of 0.81 (95% confidence interval, 0.67 to 0.98). The OR varied little with lymphoma type, sex, age, and calendar period. The OR for GCA was 0.67 (0.48 to 0.98) and for PMR, 0.83 (0.67 to 1.04).CONCLUSIONS:Treated GCA is not associated with increased lymphoma risks, which suggests that even at considerable cumulative doses, steroids may not appreciably increase lymphoma risk.

- BACKGROUND: There are limited data on survival patterns among patients with monoclonal gammopathy of undetermined significance. DESIGN AND METHODS: We compared the survival of 4,259 patients with monoclonal gammopathy of undetermined significance, collected from hematology outpatient units in Sweden, with the survival of the general population by computing relative survival ratios. We also compared causes of death in these patients with those in 16,151 matched controls. RESULTS: One-, 5-, 10-, and 15-year relative survival ratios were 0.98 (95% CI 0.97-0.99), 0.93 (0.91-0.95), 0.82 (0.79-0.84), and 0.70 (0.64-0.76), respectively. Younger age at diagnosis of the gammopathy was associated with a significantly lower excess mortality compared to that in older patients (p<0.001). The excess mortality among patients with gammopathy increased with longer follow-up (p<0.0001). IgM (versus IgG/A) gammopathy was associated with a superior survival (p=0.038). Patients with monoclonal gammopathy of undetermined significance had an increased risk of dying from multiple myeloma (hazards ratio (HR)=553; 95% CI 77-3946), Waldenström's macroglobulinemia (HR=infinity), other lymphoproliferative malignancies (6.5; 2.8-15.1), other hematologic malignancies (22.9; 8.9-58.7), amyloidosis (HR=infinity), bacterial infections (3.4; 1.7-6.7), ischemic heart disease (1.3; 1.1-1.4), other heart disorders (1.5; 1.2-1.8), other hematologic conditions (6.9; 2.7-18), liver (2.1; 1.1-4.2), and renal diseases (3.2; 2.0-4.9). CONCLUSIONS: Our finding of decreased life expectancy in patients with monoclonal gammopathy of undetermined significance, which was most pronounced in the elderly and explained by both malignant transformation and non-malignant causes, is of importance in the understanding and clinical management of this disease. The underlying mechanisms may be causally related to the gammopathy, but may also be explained by underlying disease that led to the detection of the hematologic disease. Our results are of importance since they give a true estimation of survival in patients with monoclonal gammopathy of undetermined significance diagnosed in clinical practice.

- Young-adult-onset (15-44 years of age) Hodgkin lymphoma (HL) is believed to arise as a consequence of late primary infection in susceptible individuals. The properties of this susceptibility remain little understood. We have previously reported an increased occurrence of HL in patients with rheumatoid arthritis and among their offspring, suggesting that susceptibility to autoimmunity might be of importance also in the pathogenesis of HL. To explore this hypothesis, we assessed the association of personal and family history of diabetes mellitus, with risk of subsequent HL in a population-based case-control study, including as cases all individuals diagnosed with HL above 15 years of age 1964-1999 (n = 6,873) in Sweden, and matched population controls (n = 12,565). First-degree relatives of cases and controls were identified through linkage with the Multi-generation Register. We identified discharges listing diabetes mellitus through linkage with the Inpatient Register (1964-2000). We used odds ratios (OR) as measures of relative risk. Cases with young-adult-onset HL were less likely to have a personal (OR =0.5, 95% CI 0.2-1.1) or family (OR =0.7, 95% CI 0.6-0.8) history of diabetes mellitus. In contrast, HL diagnosed at older ages was neither associated with a personal (OR =1.0) nor family (OR =1.0) history of diabetes mellitus. These findings suggests that characteristics of the immune system associated with conditions such as diabetes mellitus type I are of importance in the pathogenesis of young-adult-onset HL.Copyright 2005 Wiley-Liss, Inc.

- BACKGROUND: Campylobacter jejuni is widespread in the environment and is the major cause of bacterial gastroenteritis in humans. In the present study we use microarray-based comparative genomic hybridizations (CGH), pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) to analyze closely related C. jejuni isolates from chicken and human infection. RESULTS: With the exception of one isolate, the microarray data clusters the isolates according to the five groups determined by PFGE. In contrast, MLST defines only three genotypes among the isolates, indicating a lower resolution. All methods show that there is no inherit difference between isolates infecting humans and chicken, suggesting a common underlying population of C. jejuni. We further identify regions that frequently differ between isolates, including both previously described and novel regions. Finally, we show that genes that belong to certain functional groups differ between isolates more often than expected by chance. CONCLUSION: In this study we demonstrated the utility of 70-mer oligonucleotide microarrays for genotyping of Campylobacter jejuni isolates, with resolution outperforming MLST.

- Individual measures of quality of life (QoL) have been initiated to overcome the possible limitations with standardized measures using predefined domains for evaluation. The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) uses personal interviews to explore the five most important areas in life, both positive and negative, crucial for QoL. The nominated areas are rated regarding satisfaction and weighted to capture the importance of each selected area. The Swedish version has been extended with a disease-specific module, which evaluates the areas in life influenced by disease. The aim of this study was to validate the disease-specific SEIQoL-DW and furthermore, to evaluate the influence of the importance ratings on the overall index score in a cohort of Hodgkin lymphoma survivors. The results support the construct validity of the disease-specific SEIQoL-DW and indicate that the instrument appears to be a sensitive measure with ability to differentiate between groups with disparate subjective health status. The SEIQoL-DW succeeds to capture both positive and negative areas in life influenced by disease. The present study gave no evidence that the weighting procedure has any impact on the total index. The results support the use of the new extended version including a disease-specific module.
