Functional disability and death wishes in older Europeans: results from the EURODEP concerted action

Purpose

Physical illness has been shown to be a risk factor for suicidal behaviour in older adults. The association between functional disability and suicidal behaviour in older adults is less clear. The aim of this study was to examine the relationship between functional disability and death wishes in late life.

Methods

Data from 11 population studies on depression in persons aged 65 and above were pooled, yielding a total of 15,890 respondents. Level of functional disability was trichotomised (no, intermediate, high). A person was considered to have death wishes if the death wish/suicidal ideation item of the EURO-D scale was endorsed. Odds ratios for death wishes associated with functional disability were calculated in a multilevel logistic regression model.

Results

In total, 5 % of the men and 7 % of the women reported death wishes. Both intermediate (OR 1.89, 95 % CI 1.42; 2.52) and high functional disability (OR 3.22, 95 % CI 2.34; 4.42) were associated with death wishes. No sex differences could be shown. Results remained after adding depressive symptoms to the model.

Conclusions

Functional disability was independently associated with death wishes in older adults. Results can help inform clinicians who care for older persons with functional impairment.     

Histamine: a novel approach to cancer immunotherapy

The functions of intratumoral lymphocytes in many human malignant tumors are inhibited by reactive oxygen species (ROS), generated by adjacent monocytes/macrophages (MO). In vitro data suggest that immunotherapeutic cytokines such as interleukin-2 (IL-2) or interferon-alpha (IFN-alpha) only weakly activate T cells or natural killer (NK) cells in a reconstituted environment of oxidative stress and that inhibitors of the formation of ROS or scavengers of ROS synergize with IL-2 and IFN-alpha to activate T cells and NK cells. In this review, we focus on the immunoenhancing properties of histamine, a biogenic amine. Histamine inhibits ROS formation in MO via H2-receptors; thereby, histamine protects NK cells from MO-mediated inhibition and synergizes with IL-2 and IFN-alpha to induce killing of NK cell-sensitive human tumor cells in vitro. Histamine also optimizes cytokine-induced activation of several subsets of T cells by affording protection against MO-inflicted oxidative inhibition. The putative clinical benefit of histamine as an adjunct to immunotherapy with IL-2 and/or IFN-alpha is currently evaluated in clinical trials in metastatic malignant melanoma and acute myelogenous leukemia.     

First-trimester diagnosis of juvenile neuronal ceroid lipofuscinosis by demonstration of fingerprint inclusions in chorionic villi

One of the most common hereditary, progressive encephalopathies in children--juvenile neuronal ceroid lipofuscinosis (NCL)--lacks methods for carrier detection and prenatal diagnosis. A transcervical chorionic villus biopsy was performed at 9 completed weeks in a fetus at high risk of this disease. The syncytiotrophoblast of the chorionic villi contained fingerprint inclusions similar to those observed in various cells from children with this disease. Together with previous reports of second-trimester diagnosis in a case with late-infantile NCL (MacLeod et al., 1984, 1985), the presence of typical inclusions in placental tissue sampled at term in the infantile NCL (Rapola et al., 1987) and the lack of pathological alterations in one fetus at high risk of juvenile NCL and without clinical and morphological signs of disease at the age of 15 months (Kohlschutter et al., 1989), our findings strongly indicate that an early prenatal diagnosis of (juvenile) NCL is possible.     

Direct hospital resource utilization and costs of treating patients with multiple myeloma in Southwest Sweden: a 5-year retrospective analysis

BACKGROUND: Approximately 570 patients are diagnosed with multiple myeloma (MM) in Sweden each year. Few studies have estimated the cost of treatment for these patients. OBJECTIVE: The purpose of this study was to retrospectively investigate the direct hospital resource utilization and costs associated with the treatment of patients with MM in southwest Sweden. METHODS: Patients aged > or =18 years who initiated first-line chemotherapy in the year 2001 at hospitals in southwestern Sweden were included in this retrospective chart review. Direct hospital-based resources and their corresponding costs (year-2006 euros) for each patient were calculated until the patient's death, or until December 31, 2005. Costs for outpatient and terminal stage care related to MM were not included. RESULTS: Ninety-four patients were included; 20 were still alive at study completion. Mean age at diagnosis was 76 years and patients were followed for a mean of 32.7 months; 55% were males and 74% had at least 1 comorbidity. First-, second-, and third-line treatment lasted a mean of 24.3, 5.8, and 2.6 months, and included 2.8, 2.6, and 3.1 chemotherapy drugs per patient, respectively. Of the 80 patients who received first-line chemotherapy, 72 were prescribed melphalan and 55 patients received a combination of melphalan and prednisone, as recommended by Swedish treatment guidelines. The mean total cost per patient was euro88,199, or euro2770 per patient-month. Therapy-induced and comorbidity-related events constituted 42% of total costs, as much as autologous stem-cell transplantation and inpatient care together. Chemotherapy, bisphosphonate, and blood cell-enhancement drugs each amounted to only 2% of total costs, but chemotherapy drugs increased from euro29/month in first-line therapy to euro453/month in third-line therapy. CONCLUSIONS: The cost of treating Swedish patients with MM varied greatly between individuals but, overall, chemotherapy drugs constituted only a minor part of the total monthly cost (2%), whereas costs for inpatient stays and therapy-induced adverse events or comorbidity-related events accounted for 35% and42%, respectively. There was no significant differencein monthly cost between treatment lines.     

Plasma thrombopoietin levels in thrombocytopenic states: implication for a regulatory role of bone marrow megakaryocytes

To evaluate the diagnostic value of thrombopoietin (TPO, c-mpl ligand) measurements, and clarify the regulatory mechanisms of TPO in normal and in thrombocytopenic conditions, the plasma TPO concentration was determined in normal individuals (n = 20), umbilical cord blood (n = 40), chronic idiopathic thrombocytopenic purpura (ITP; n = 16), in severe aplastic anaemia (SAA; n = 3), chemotherapy-induced bone marrow hypoplasia (n = 10), myelodysplastic syndrome (MDS; n = 11), and sequentially during peripheral blood progenitor cell transplantation (n = 7). A commercially available ELISA and EDTA-plasma samples were used for the analysis. The plasma TPO concentration in the normals and umbilical cord blood were 52 ± 12 pg/ml and 66 ± 12 pg/ml, respectively. The corresponding values in patients with SAA and chemotherapy-induced bone marrow hypoplasia were 1514 ± 336 pg/ml and 1950 ± 1684 pg/ml, respectively, and the TPO concentration, measured sequentially after myeloablative chemotherapy and peripheral blood progenitor cell transplantation, was inversely related to the platelet count. In contrast, the plasma TPO recorded in patients with ITP (64 ± 20 pg/ml) and MDS (68 ± 23 pg/ml) were only slightly higher than normal levels. In conclusion, TPO levels were significantly elevated in patients in which bone marrow megakaryocytes and platelets in circulation were markedly reduced, whereas TPO levels were normal in ITP patients, and only slightly increased in the MDS patients. These latter patients displayed a preserved number of megakaryocytes in bone marrow biopsies. Our data support the suggestion that megakaryocyte mass affects the plasma TPO concentration. In thrombocytopenic patients a substantially increased plasma TPO implies deficient megakaryocyte numbers. However, TPO measurements do not distinguish between ITP and thrombocytopenia due to dysmegakaryopoiesis, as seen in MDS patients.     

Personal and family history of immune-related conditions increase the risk of plasma cell disorders: a population-based study

The associations between immune-related conditions and multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) have previously been investigated with inconsistent results. In a large population-based study, we identified 19 112 patients with MM, 5403 patients with MGUS, 96 617 matched control subjects, and 262 931 first-degree relatives. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for the association of MM and MGUS with immune-related conditions by use of logistic regression. A personal history of all infections combined was associated with a significantly increased risk of MM (OR = 1.2; 95% CI, 1.1-1.3), and a personal history of all conditions in the categories infections (OR = 1.6; 95% CI, 1.5-1.7), inflammatory conditions (OR = 1.4; 95% CI, 1.2-1.5), and autoimmune diseases (OR = 2.1; 95% CI, 1.9-2.4) was associated with a significantly increased risk of MGUS. Several specific immune-related conditions elevated the risk of MM and/or MGUS. A family history of autoimmune disease was associated with a significantly increased risk of MGUS (OR = 1.1; 95% CI, 1.00-1.2), but not MM. Our findings suggest that immune-related conditions and/or their treatment are of importance in the etiology of MGUS and possibly MM. The association of both personal and family history of autoimmune disease with MGUS indicates the potential for shared susceptibility for these conditions.     

Impact of age on survival after intensive therapy for multiple myeloma: a population-based study by the Nordic Myeloma Study Group

The value of intensive therapy, including autologous stem cell transplantation, in newly diagnosed myeloma patients >60 years is not clear. We evaluated the impact of age (<60 years vs. 60-64 years) on survival in a prospective, population-based setting and compared survival with conventionally treated historic controls. The prospective population comprised 452 patients registered between 1998 and 2000. Of these, 414 received intensive therapy. The historic population, derived from our most recent population-based study on conventional therapy, comprised 281 patients. Of these, 243 fulfilled our eligibility criteria for intensive therapy. For patients undergoing intensive therapy it was found that two factors, beta-2-microglobulin and age <60 years vs. 60-64 years, had independent prognostic impact on survival. However, compared with the historic controls a survival advantage was found both for patients <60 (median 66 months vs. 43 months, P < 0.001) and 60-64 years (median 50 months vs. 27 months; P = 0.001). We conclude that in a population-based setting higher age adversely influences outcome after intensive therapy. Our results indicate that intensive therapy prolongs survival also at age 60-64 years but with less superiority than in younger patients.     

Melphalan 100 mg/m2 with stem cell support as first relapse treatment is safe and effective for myeloma patients with long remission after autologous stem cell transplantation

Introduction: Today, a number of therapeutic options are available as the patient with myeloma relapses from initial treatment with high‐dose melphalan and autologous stem cell transplantation (ASCT). For patients who experience a durable response to primary ASCT, retreatment with high‐dose melphalan is recommended by many current guidelines. Yet, toxicity is an important aspect in the choice of relapse treatment, and a second ASCT in this setting could be associated with enhanced toxicity. As the goal for the treatment for relapsed myeloma should be disease control while maintaining quality of life, lower doses of melphalan might be preferable. Methods and Objectives: In this retrospective study, we account for the outcome of 66 patients with myeloma in first systemic relapse after ASCT, who were treated with intermediate‐dose melphalan, 100 mg/m², and stem cell support (MEL 100). The aim was to evaluate this treatment in relation to prior response duration after initial ASCT and with respect to response rate, toxicity and survival. Results: The overall response rate was 62%. There was limited, mostly haematological, toxicity, and no treatment–related mortality was observed. The median progression‐free survival (PFS) was 8.5 months, and the median overall survival was 24 months. Patients with time to progression of 34 months or more (n = 17; ≥75th percentile) after initial ASCT had a median PFS of 12.5 months after MEL 100. Conclusion: For patients with a long‐lasting response after ASCT, MEL 100 could be a therapeutic option with low toxicity and with efficacy comparable to newer immunomodulatory drugs.
