RESUMEN

BACKGROUND: Atopic eczema (AE) may be associated with several mental health problems. In Germany, existing data from selected patient cohorts may lead to misestimation of the problem. OBJECTIVES: We aimed to cross-sectionally determine associations of AE with depression, anxiety, quality of life (QoL) and social interactions in subjects from the population-based LIFE-Adult-Study. METHODS: Subjects underwent standardized interviews (medical history) and answered standardized questionnaires [Centre of Epidemiologic studies-Depression scale (CES-D), Generalized Anxiety Disorder (GAD-7), Lubben Social Network Scale (LSNS), Short Form Health Survey (SF-8)]. We compared data from subjects with AE with those from subjects with selected other chronic/disabling diseases (cardiovascular, diabetes, cancer) and adjusted for selected sociodemographic parameters. Multivariate binary logistic regression was used for categorical variables, linear regression for continuous variables. RESULTS: Out of 9104 adults included (57% female, median age 54 years), 372 (4.1%) had a history of AE. Compared with controls, subjects with AE showed higher scores for depressive symptoms (9.3% vs. 6.3%; P < 0.001) and anxiety (8.4% vs. 5.6%, P < 0.001). Odds ratio (OR) was 1.5 [CI 1.0; 2.3] (P = 0.031) for depression, which was comparable to OR in patients with a history of cancer (OR 1.6 [1-2.3], P = 0.001. OR for anxiety in AE was 1.5 [1.0; 2.2], P < 0.049, which was slightly higher than in diabetes mellitus (OR 1.2) and stroke (OR 1.4). Other than in diabetes and/or stroke, we did not find a significant association between AE and social isolation. QoL scores were lower in AE than in controls (mean 46.9 vs. 48.0, P < 0.001 for physical and 50.6 vs. 52.5, P < 0.001 for mental components). CONCLUSIONS: Subjects with AE showed higher values for depression and anxiety as well as lower QoL scores compared to controls. With regard to depression, odds in AE and cancer were hardly different. Medical care of AE patients should therefore include mental health evaluation and treatment if indicated.

RESUMEN

BACKGROUND: Cancer patients can feel depression and anxiety any time after a cancer diagnosis. The Generalized Anxiety Disorder Scale (GAD-7) is an instrument for the assessment of anxiety. The main objective of this work was to compare general anxiety levels between cancer survivors and individuals without a history of cancer in a population-based study (LIFE-ADULT) with 10,000 participants. METHODS: All participants (18-80 years) completed the GAD-7 and other psychological and medical questionnaires. A score of 10 or greater for GAD-7 (of total 21) indicates a probable generalized anxiety disorder. RESULTS: 954 participants reported a diagnosis of cancer in their medical history. In the multivariate analysis an anxiety disorder was associated with prior cancer diagnosis (OR: 1.8; 95% CI [1.4-2.4]), age -every additional year- (OR: 0.983; [0.976-0.991]), female gender (OR: 1.8; [1.5-2.2]) and low socioeconomic status (OR: 2.0; [1.7-2.5]) all p < 0.001. There were no significant associations between general anxiety and other comorbidities, such as myocardial infarction (OR: 1.0; p = 0.948), stroke (OR: 1.4; p = 0.237) or diabetes (OR: 1.0; p = 0.326). There was also no significant difference in anxiety disorder among cancer survivors regarding the time passed since the initial cancer diagnosis (OR: 1.1; [0.6-1.9], p = 0.804 comparing 5-10 years after a diagnosis of cancer vs. ≤5 years and OR: 0.6; [0.4-1.1], p = 0.107 comparing >10 vs. ≤5 years). LIMITATIONS: This study has a cross-sectional character, therefore, causal conclusions cannot be drawn. CONCLUSION: Cancer survivors may require screening for anxiety disorders and long-term professional psychosocial support.

RESUMEN

Effective methods to increase awareness of preventable infectious diseases are key components of successful control programmes. Rabies is an example of a disease with significant impact, where public awareness is variable. A recent awareness campaign in a rabies endemic region of Azerbaijan provided a unique opportunity to assess the efficacy of such campaigns. A cluster cross-sectional survey concerning rabies was undertaken following the awareness campaign in 600 households in 38 randomly selected towns, in districts covered by the campaign and matched control regions. This survey demonstrated that the relatively simple awareness campaign was effective at improving knowledge of rabies symptoms and vaccination schedules. Crucially, those in the awareness campaign group were also 1·4 times more likely to report that they had vaccinated their pets, an essential component of human rabies prevention. In addition, low knowledge of appropriate post-exposure treatment and animal sources of rabies provide information useful for future public awareness campaigns in the region and other similar areas.

RESUMEN

The Caucasus is a region of geopolitical importance, in the gateway between Europe and Asia. This geographical location makes the region equally important in the epidemiology and control of transboundary infectious diseases such as rabies. Azerbaijan is the largest country in the Caucasus, and although rabies is notifiable and considered endemic, there is little information on the burden of human and animal rabies. Here, we describe a cross-disciplinary international collaboration aimed at improving rabies control in Azerbaijan. Partial nucleoprotein gene sequences were obtained from animal rabies cases for comparison with those from surrounding areas. Reported human and animal rabies cases between 2000 and 2010 were also reviewed and analysed by region and year. Comparison of rabies virus strains circulating in Azerbaijan demonstrates more than one lineage of rabies virus circulating concurrently in Azerbaijan and illustrates the need for further sample collection and characterization. Officially reported rabies data showed an increase in human and animal rabies cases, and an increase in animal bites requiring provision of post-exposure prophylaxis, since 2006. This is despite apparently consistent levels of dog vaccination and culling of stray dogs.

RESUMEN

BACKGROUND: To improve outcome of elderly patients with diffuse large B-cell lymphoma, dose-dense rituximab was evaluated in the prospective DENSE-R-CHOP-14 trial. PATIENTS AND METHODS: Rituximab (375 mg/m(2)) was given on days 0, 1, 4, 8, 15, 22, 29, 43, 57, 71, 85, and 99 together with six CHOP-14 cycles. Results were to be compared with patients who had received the same chemotherapy in combination with eight 2-week applications of rituximab in RICOVER-60. RESULTS: One hundred twenty-four patients are assessable. Dose-dense rituximab resulted in considerably higher serum levels during the first 50 days of treatment, but rituximab exposure time was not prolonged. Grade 3 and 4 infections were exceptionally high in the first 20 patients without anti-infective prophylaxis, but decreased after introduction of prophylaxis with aciclovir and cotrimoxazole in the remaining 104 patients (from 13% to 6% per cycle and from 35% to 18% per patient; P = 0.007 and P = 0.125, respectively). Patients with international prognostic index = 3-5 had higher complete response/complete response unconfirmed rates (82% versus 68%; P = 0.033) than in the respective RICOVER-60 population, but this did not translate into better long-term outcome, even though male hazard was decreased (event-free survival: from 1.5 to 1.1; progression-free survival: from 1.7 to 1.1; overall survival: from 1.4 to 1.0). CONCLUSIONS: Dose-dense rituximab achieved higher rituximab serum levels, but was not more effective than eight 2-week applications in the historical control population, even though minor improvements in poor-prognosis and male patients cannot be excluded. The increased, though manageable toxicity, precludes its use in routine practice. Our results strongly support anti-infective prophylaxis with aciclovir and cotrimoxazole for all patients receiving R-CHOP.

RESUMEN

Bi-weekly (R)-CHOP therapy is one of the standard treatmentS for elderly patients with aggressive B-cell lymphoma, but it is only feasible with supportive G-CSF treatment. In the trials of the DSHNHL, either unpegylated G-CSF was given daily over 7 or 10 days or pegylated G-CSF was applied at day 4 of each cycle. These schedules were planned on the basis of simulations of a biomathematical pharmacokinetic/pharmacodynamic model. By analysing the observed data, we investigated whether our model predictions were correct and whether even better schedules can be proposed. We used data on 249 matched patients of two prospective trials, RICOVER-60 and PEGFILGRASTIM. The three G-CSF-schedules showed similar outcomes regarding leukocytopenia, infections and days in hospital, with pegylated G-CSF having slightly but not significantly better scores in all three endpoints. Regarding pegylated G-CSF, the best timing is predicted to be any day between days 4 and 7. With respect to unpegylated G-CSF, the starting day is less important, but it should be continued until the end of each cycle.The three G-CSF-schedules are interchangeable in (R)-CHOP-14 for elderly patients with aggressive B-cell lymphoma. Our model correctly predicts time courses of leukocytes. Further model predictions are presented, which can be tested in subsequent clinical trials.

RESUMEN

BACKGROUND: To describe incidence, risk factors, and influence of treatment on occurrence of central nervous system (CNS) relapse or progression in younger patients with aggressive B-cell lymphoma. PATIENTS AND METHODS: We analyzed 2210 patients with aggressive B-cell lymphoma treated on various studies for CNS relapse/progression. Treatment consisted of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) ± etoposide. Six hundred and twenty patients also received rituximab. CNS prophylaxis was intrathecal methotrexate on High-CHOEP and MegaCHOEP phase III studies if upper neck, head, bone marrow, or testes were involved. RESULTS: Fifty-six of 2196 patients (2.6%) developed CNS disease. It occurred early (median 7.0 months), median survival was 5.0 months. Patients with age-adjusted International Prognostic Index (aaIPI) 0 or 1 treated with rituximab showed a low risk for CNS disease (2-year rates: 0% or 0.5%), and rituximab decreased the risk (relative risk 0.3, 95% confidence interval 0.1-0.9, P = 0.029). Patients with aaIPI 2 or 3 showed a moderate risk (4.2%-9.7%) and no significant reduction of CNS disease with rituximab. CNS prophylaxis was of no significant benefit. CONCLUSIONS: In younger patients with aaIPI 0 or 1, CNS relapse/progression is very rare; in patients with aaIPI 2 or 3, the risk is higher (up to 10%) and requires new diagnostic strategies and treatment.

RESUMEN

BACKGROUND: To study the effects of deferring pegfilgrastim until day 4 on the reduction of chemotherapy-induced leukocytopenia. PATIENTS AND METHODS: Patients of age 61-80 years with aggressive lymphoma were randomly assigned to receive 6 mg pegfilgrastim on day 2 or 4 of a 2-week chemotherapy regimen (R-CHOP-14). RESULTS: Two hundred and ninety-two and 313 chemotherapy cycles were evaluable in 103 patients. Post-nadir pegfilgrastim serum levels were higher after day 4 than after day 2 application. This was associated with an attenuated leukocyte nadir after day 4 pegfilgrastim and there were fewer days with leukocytes <2 × 10(3)/mm(3) compared with day 2 pegfilgrastim. Grade 3 and 4 leukocytopenias (70% versus 43.3%; P < 0.001) and grade 4-only leukocytopenias (47% versus 20.5%; P < 0.001) were more frequent after day 2 pegfilgrastim. There were more chemotherapy cycles with grade 3 and 4 infections after day 2 than day 4 pegfilgrastim (9.4% versus 6.0%; P = 0.118). Interventional antibiotics were given more often after day 2 than after day 4 pegfilgrastim (30.7% versus 21.9% of cycles; P = 0.008). There were five deaths during leukocytopenia after day 2 and none after day 4 pegfilgrastim (P = 0.027). CONCLUSIONS: Administration of pegfilgrastim on day 4 was more effective in reducing severe leukocytopenias and resulted in fewer deaths during leukocytopenia. Pegfilgrastim should be given on day 4 to better exploit its myeloprotective potential.

RESUMEN

BACKGROUND: Bleeding from esophageal varices is a severe complication of portal hypertension. Endoscopic band ligation (EBL) is the treatment of choice for acute variceal bleeding. It is also performed for primary and secondary prophylaxis of bleeding from esophageal varices. After EBL, patients are at risk of postinterventional bleeding; the risk factors for this complication are poorly evaluated. METHODS: We retrospectively analyzed data from patients who underwent EBL. We evaluated clinical data, laboratory and endoscopic findings. RESULTS: 255 patients with 387 ligation sessions were included in the analysis. Patients with bleeding complications had a significantly higher severity of liver disease as measured by a higher Child-Pugh score (10.5 vs. 8, p = 0.002), lower albumin (26.5 vs. 31.9 [g/L], p = 0.0001) and lower prothrombin activity (46.5 vs. 70 [%], p = 0.0001). The incidence of bacterial infection was significantly higher in patients with postinterventional bleeding. As well, the white blood cell count was significantly higher in the bleeding group (9.5 vs. 6.5 [× 10 (9) /L], p = 0.030). In patients with bleeding events we observed an elevated heart rate compared to those without this complication (80 vs. 72 [bpm], p = 0.017). Furthermore, we found a lower hemoglobin level (5.9 vs. 6.4 [mmol/L], p = 0.028) and a lower hematocrit (0.280 vs. 0.314, p = 0.031) in the bleeding group. Younger patients suffered more often from postinterventional bleeding (52.5 vs. 58 [years], p = 0.012). CONCLUSION: There are clinical data which can be ascertained easily in order to reflect the risk of bleeding complications after EBL.

RESUMEN

BACKGROUND: T-cell lymphomas (T-NHL) generally carry a poor prognosis. High-dose therapy (HDT) and autologous stem cell transplantation (ASCT) are increasingly used to treat younger patients. DESIGN AND METHODS: We treated patients <61 years with high-risk aggressive lymphoma with four to six courses of dose-escalated CHOP plus etoposide (MegaCHOEP) necessitating repeated ASCT. Outcomes of patients with mature T-NHL (excluding anaplastic lymphoma kinase-positive anaplastic large cell lymphoma) and aggressive B-NHL were compared using multivariate Cox regression analysis. RESULTS: Compared with 84.4% of B-NHL patients, 66.7% of T-NHL patients were able to receive all treatments; the rates of progressive disease were 27.3% in T-NHL and 16.3% in B-NHL patients. At 3 years, event-free survival (EFS) and overall survival were significantly worse for T-NHL [25.9% confidence interval (CI) 10.4% to 41.4% and 44.5% CI 26.5% to 62.5%) than for B-NHL patients (60.1% CI 52.1% to 68.1%; P < 0.001 and 63.4% CI 55.4% to 71.4%; P = 0.016). In multivariate analysis, T-NHL was a strongly significant adverse risk factor for EFS (relative risk 2.2, P = 0.001). CONCLUSIONS: MegaCHOEP for T-NHL patients was no better than other high-dose regimens and was unable to address the major problems of HDT/ASCT: neither early progressions nor early relapses were reduced. This study sheds some doubt on expectations that HDT/ASCT will significantly improve outcomes for patients with T-NHL.

RESUMEN

BACKGROUND: Recently published data indicate that host germline variations in immune genes can influence the outcome of lymphoma patients. Interleukin (IL)-4 and IL13 are crucial immune factors and may influence the course of the disease. Both cytokines signal through the interleukin-4 receptor (IL4R). Therefore, we investigated whether polymorphisms of IL4, IL13 and IL4R genes could predict the outcome of diffuse large B-cell lymphoma (DLBCL) patients. METHODS: In 228 DLBCL samples of the German High-Grade Non-Hodgkin's Lymphoma Study Group, the polymorphisms of IL4 (-524CT, rs2243250), IL13 (-1069CT, rs1800925) and IL4R (I75V, rs1805010; S503P, rs1805015; Q576R, rs1801275) were analyzed and the soluble interleukin-4 receptor (sIL4R) serum level was measured before the start of chemotherapy. RESULTS: Patients harboring IL4R V75 (IL4R(I75V-AG) and IL4R(I75V-GG)) had shorter overall survival (OS) (P = 0.044) and event-free survival (EFS) (P = 0.056) periods compared with I75 carriers (IL4R(I75V-AA)). Multivariate analysis adjusted to the International Prognostic Index revealed a relative risk of 1.9 for carriers of the IL4R V75 (P = 0.011) in relation to OS. DLBCL patients homozygous for the IL4R I75 and low sIL4R serum levels have the most favorable OS and EFS. CONCLUSIONS: These data support the role for host germline gene variations of immunologically important factors like the IL4R I75V gene variation to predict the survival in DLBCL patients.

RESUMEN

Recent retrospective studies of heterogeneously treated patients have suggested that chromosomal aberrations of the MYC gene locus indicate an unfavorable prognosis in diffuse large B-cell lymphoma (DLBCL). Here, we investigated the prognostic impact of MYC aberrations analyzed by interphase fluorescence in situ hybridization in 177 patients with de novo DLBCL treated within the two prospective, randomized trials non-Hodgkin's lymphoma NHL-B1 and NHL-B2. MYC aberrations were detected in 14 DLBCL (7.9%). In a univariate analysis compared with MYC-negative DLBCL, MYC-positive cases showed a significantly shorter overall survival (OS) (P=0.047) and relevantly, though not significantly, shorter event-free survival (EFS) (P=0.062). In a Cox model adjusted for the international prognostic index, the presence of a MYC gene rearrangement was the strongest statistically independent predictor of OS (relative risk 3.4, P=0.004) and EFS (relative risk 2.5, P=0.015), and this also held true when the cell-of-origin signature detected by immunohistochemistry was included in the model.

RESUMEN

BACKGROUND: The addition of etoposide to combination chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone [etoposide to combination chemotherapy with cyclophosphamide, vincristine and prednisone (CHOEP)] improved outcome of young patients with good-prognosis aggressive lymphoma. To improve results further, the maximal dose-escalated version of CHOEP-21 tolerable without stem-cell support (high CHOEP: cyclophosphamide 1400 mg/m2, doxorubicin 65 mg/m2, vincristine 2 mg, etoposide 175 mg/m2 x3, prednisone 100 mg x5) was compared with CHOEP-21. PATIENTS AND METHODS: Intention-to-treat analysis of 389 young (18-60 years) patients with good-prognosis (age-adjusted International Prognostic Index = 0, 1) aggressive lymphoma randomized to CHOEP-21 (n = 194) or high CHOEP (n = 195). RESULTS: There was no difference in 3-year event-free (64% versus 67%; P = 0.734) or overall survival (83% versus 87%; P = 0.849). Neither low-risk nor low-intermediate risk patients benefited from high CHOEP. High CHOEP was more toxic than CHOEP-21 (grades 3 and 4 leukocytopenia 100% versus 87.2%, P < 0.001; thrombocytopenia 80.8% versus 9.6%, P < 0.001; infections 35% versus 11%, P < 0.001; therapy-associated deaths 3.1% versus 0%, P = 0.03). CONCLUSION: Dose-escalated CHOEP-21 does not provide clinical benefit for young patients with good-prognosis aggressive lymphomas. Since differences between chemotherapy regimens are compressed by the addition of rituximab, the results of this trial have bearing on strategies aiming to improve outcome of good-prognosis aggressive lymphomas in the rituximab era.

RESUMEN

BACKGROUND: Central nervous system (CNS) relapse is a devastating and usually fatal complication of aggressive lymphoma. The extent of the disease, the proliferation rate and the sites of extranodal involvement have been discussed as risk factors. We analyzed the patients treated on protocols of the German High-Grade Non-Hodgkin's Lymphoma Study Group (DSHNHL) between 1990 and 2000, evaluated the rate and prognostic factors for CNS recurrence and developed a risk model trying to identify subsets of patients suitable for future prophylactic strategies. PATIENTS AND METHODS: From 1993 to 2000, 1399 patients [60 years irrespective of LDH] were randomized to receive six cycles of combination chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP)-21, CHOP-14 or six cycles of CHOP+etoposide (CHOEP)-21, CHOEP-14 in a 2x2 factorial study design in the NHL-B1/B2 studies. From 1990 to 1997, 312 patients
