Association Between FEV1 Decline Rate and Mortality in Long-Term Follow-Up of a 21-Patient Pilot Clinical Trial of Inhaled Liposomal Cyclosporine Plus Standard-of-Care Versus Standard-of-Care Alone for Bronchiolitis Obliterans Syndrome After Lung Transplantation.

BACKGROUND The association between forced expiratory volume in 1 second (FEV1) trajectory and mortality in bronchiolitis obliterans syndrome (BOS) is not well defined. Using long-term data from a prior clinical trial of inhaled liposomal cyclosporine A (L-CsA-I) for lung transplant patients with BOS, this study examined the association between longitudinal FEV1 change and mortality. MATERIAL AND METHODS We analyzed long-term data from a clinical trial which randomized 21 patients with BOS (³20% decrease in FEV1 from personal maximum) to receive L-CsA-I plus standard-of-care (n=11) or standard-of-care (SOC) alone (n=10) for 24 weeks. A joint statistical model, combining a linear mixed model for FEV1 change and Cox regression for mortality, was utilized to examine the overall association between FEV1 trajectory and mortality during follow-up. RESULTS The 21 trial participants (10 single, 11 double lung recipients) had a mean FEV1 of 1.7±0.6 Liters at randomization. Median follow-up post-randomization was 35 months. In joint model analysis, 1 percent FEV1 decline predicted 1.076-fold increased mortality risk (95% confidence interval: -0.998 to 1.160, p=0.058). FEV1 decline was reduced by 2.6% per year in L-CsA-I patients compared to SOC (p=0.210), and overall survival at 1/3/5 years was 91%/64%/27% vs 90%/20%/0% for L-CsA-I versus SOC, respectively (p=0.164). CONCLUSIONS In BOS patients, greater longitudinal FEV1 decline predicts increased mortality. Trends towards prolonged stabilization of FEV1 and improved survival were observed with L-CsA-I receipt. Further analyses will aid in evaluating the utility of FEV1 change as a survival predictor, having implications in BOS management and future trial design.

Autologous-allogeneic versus autologous tandem stem cell transplantation and maintenance therapy with thalidomide for multiple myeloma patients less than 60 years of age: a prospective phase II study

The role of autologous-allogeneic tandem stem cell transplantation (alloTSCT) followed by maintenance as upfront treatment for multiple myeloma (MM) is controversial. Between 2008 and 2014 a total of 217 MM patients with a median age of 51 years were included by 20 German centers within an open-label, parallel-group, multi-center clinical trial to compare alloTSCT to auto tandem transplantation TSCT (autoTSCT) followed by a 2-year maintenance therapy with thalidomide (100 mg/d) in both arms with respect to relapse/progression-free survival (PFS) and other relevant outcomes. A total of 178 patients underwent second SCT (allo n = 132 and auto n = 46). PFS at 4 years after the second SCT was 47% (CI: 38-55%) for alloTSCT and 35% (CI: 21-49%) for autoTSCT (p = 0.26). This difference increased to 22% at 8 years (p = 0.10). The cumulative incidences of non-relapse mortality (NRM) and of relapse at 4 years were 13% (CI: 8-20%) and 2% (CI: 0.3-2%) (p = 0.044) and 40% (CI: 33-50%) and 63% (CI: 50-79%) for alloTSCT and autoTSCT (p = 0.04), respectively. The difference for relapse/progression increased to 33% (alloTSCT: 44%, autoTSCT: 77%) at a median follow-up of 82 months (p = 0.002). Four-year OS was 66% (CI: 57-73%) for alloTSCT and 66% (CI: 50-78%) for auto TSCT (p = 0.91) and 8-year OS was 52% and 50% (p = 0.87), respectively. AlloTSCT followed by thalidomide maintenance reduced the rate of recurrence or progression during a follow-up period of up to 10 years but failed to improve PFS significantly.

Ivy leaves extract EA 575 in the treatment of cough during acute respiratory tract infections: meta-analysis of double-blind, randomized, placebo-controlled trials.

Ivy leaves extracts have been used successfully to treat acute cough, and data from well-controlled trials is accumulating. We present a meta-analysis of two double-blind, randomized, placebo-controlled trials. Patients with acute respiratory tract infection (ARTI) received ivy leaves dry extract EA 575 (n = 228) or placebo (n = 162) for 7 days, followed by a 7-day period without treatment. The main efficacy outcome was the Bronchitis Severity Score (BSS). Individual patient data meta-analyses were performed using mixed models for repeated measures, analysis of covariance and logistic ordinal regression. Significant BSS differences between EA 575 and placebo occurred already after 2 days and increased until treatment end, with BSS reductions of 8.6 ± 0.2 and 6.2 ± 0.2 (marginal means ± SEM; p < 0.001). The score reduction for placebo after 7 days was comparable to that for EA 575 after 4 days. In the EA 575 group, the proportion of cough-free patients was 18.1% at treatment end and 56.2% at end of follow-up, compared to 9.3% and 25.6% for placebo, respectively. Adverse event rates for EA 575 and placebo were comparable. EA 575 reduces effectively the intensity of acute cough associated with ARTIs and leads to a significant acceleration of recovery. No safety signals were observed.

Association between ivy leaves dry extract EA 575 prescriptions and antibiotic use, sick leave duration, and repeated infections in adult patients.

OBJECTIVES: The present study aimed to analyze the association between the prescription of ivy leaf dry extract EA 575 (licensed under the trade name Prospan® in Germany) and the incidence of antibiotic use, incident bacterial complications, and days of sick leave in adult patients with cold diseases. METHODS: This retrospective cohort study was based on the IQVIA Disease Analyzer database and included adult patients from 1032 general practices in Germany with a documentation of common cold between 2017 and 2020 (index date) and prescription of either EA 575 or an antibiotic drug within 3 days after index date. 1:1 propensity score matching based on age, sex, index month, physician, health insurance status, and the Charlson Comorbidity Index was carried out. Univariable regression models were used to investigate the association between EA 575 prescription and defined outcomes. RESULTS: Data of 7034 patients treated with EA 575 and 7034 matched patients receiving an antibiotic were available. EA 575 prescription was associated with significantly lower odds of an antibiotic prescription in the time periods of 4-30 days (OR: 0.83; 95% CI: 0.72-0.96) and 31-365 days (OR: 0.44; 95% CI: 0.40-0.48) after the index date. EA 575 prescription was significantly associated with a lower rate of sick leave of more than 7 days (33.0% vs. 37.7%, OR: 0.81; 95% CI: 0.73-0.90) in patients with any sick leave, as well as with lower odds of a new cough diagnosis (OR: 0.91, 95% CI: 0.85-0.98) when compared to antibiotic prescription. CONCLUSION: Our study provides further evidence that the use of phytopharmaceuticals, in particular ivy leaf dry extract EA 575, could contribute to a reduction in the number of inappropriate antibiotic prescriptions for respiratory infection with cough symptoms.

Acute GVHD prophylaxis plus ATLG after myeloablative allogeneic haemopoietic peripheral blood stem-cell transplantation from HLA-identical siblings in patients with acute myeloid leukaemia in remission: final results of quality of life and long-term outcome analysis of a phase 3 randomised study.

BACKGROUND: We previously showed that human anti-T-lymphocyte globulin (ATLG) plus ciclosporin and methotrexate given to patients with acute leukaemia in remission, having allogeneic haemopoietic stem-cell transplantation with peripheral blood stem cells from an HLA-identical sibling donor after myeloablative conditioning, significantly reduced 2-year chronic graft-versus-host disease (cGVHD) incidence and severity, without increasing disease relapse and infections, and improves cGVHD-free and relapse-free survival (cGRFS). The aim of an extended follow-up study was the assessment of long-term outcomes, which are, in this context, scarcely reported in the literature. We report unpublished data on quality of life (QoL) from the original study and the results of a follow-up extension. METHODS: In the original open-label study, patients with acute myeloid and lymphoblastic leukaemia in first or subsequent remission, having sibling HLA-identical allogeneic peripheral blood stem-cell transplantation, were randomly assigned (1:1) to receive ATLG plus standard GVHD prophylaxis with ciclosporin and short-term methotrexate (ATLG group) or standard GVHD prophylaxis without ATLG (non-ATLG group). Conditioning regimens were cyclophosphamide 120 mg/kg with either total body irradiation (12 Gy) or busulfan (12·8 mg/kg intravenously or 16 mg/kg orally), with or without etoposide (30-60 mg/kg). Randomisation was stratified according to centre and disease risk. The primary endpoint was cumulative incidence of cGVHD at 2 years. The primary and secondary endpoints, excluding QoL, have been published. QoL, assessed using European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-HDC29 questionnaires, was an unpublished secondary endpoint, which we now report here. A follow-up extension was then done, with the primary endpoint cumulative incidence of cGVHD. Enrolment has been completed for both studies. The original trial (number, NCT00678275) and follow-up extension (number, NCT03042676) are registered at ClinicalTrials.gov. FINDINGS: In the original study, from Dec 14, 2006, to Feb 2, 2012, 161 patients were enrolled and 155 were randomly assigned to either the ATLG group (n=83) or to the non-ATLG group (n=72). In the follow-up study, which started on Feb 7, 2017, and was completed on June 30, 2017, 61 patients were included in the ATLG group and 53 were included in the non-ATLG group. Global health status showed a more favourable time course in the ATLG group compared with the non-ATLG group (p=0·02; treatment by visit interaction). ATLG was descriptively superior to non-ATLG at 24 months for physical function (points estimate -14·8 [95% CI -26·4 to -3·1]; p=0·014) and social function (-19·1 [-38·0 to -0·2]; p=0·047), gastrointestinal side-effects (8·8 [2·5-15·1]; p=0·008) and effect on family (13·5 [1·2-25·8]; p=0·032). Extended follow-up (median 5·9 years [IQR 1·7-7·9]) confirmed a lower 5-year cGVHD incidence (30·0% [95% CI 21·4-41·9] vs 69·1% [59·1-80·1]; analysis for entire follow-up, p<0·001), no increase in relapses (35·4% [26·4-47·5] vs 22·5% [14·6-34·7]; p=0·09), improved cGRFS (34·3% [24·2-44·5] vs 13·9% [7·1-22·9]; p=0·005), and fewer patients still in immunosuppression (9·6% vs 28·3%; p=0·017) in the ATLG group compared with the non-ATLG group. 5-year overall survival, relapse-free survival, and non-relapse mortality did not differ significantly between groups. INTERPRETATION: The addition of ATLG to standard GVHD prophylaxis improves the probability of surviving without disease relapse and cGVHD after myeloablative peripheral blood stem-cell transplantation from an HLA-identical sibling donor for patients with acute leukaemia in remission. Further additional benefits are better QoL and shorter immunosuppressive treatment compared with standard GVHD prophylaxis without ATLG. Therefore, in this setting, ATLG plus standard GVHD prophylaxis should be preferred over the standard GVHD prophylaxis alone. FUNDING: Neovii Biotech.

Antilymphocyte Globulin for Prevention of Chronic Graft-versus-Host Disease.

BACKGROUND: Chronic graft-versus-host disease (GVHD) is the leading cause of later illness and death after allogeneic hematopoietic stem-cell transplantation. We hypothesized that the inclusion of antihuman T-lymphocyte immune globulin (ATG) in a myeloablative conditioning regimen for patients with acute leukemia would result in a significant reduction in chronic GVHD 2 years after allogeneic peripheral-blood stem-cell transplantation from an HLA-identical sibling. METHODS: We conducted a prospective, multicenter, open-label, randomized phase 3 study of ATG as part of a conditioning regimen. A total of 168 patients were enrolled at 27 centers. Patients were randomly assigned in a 1:1 ratio to receive ATG or not receive ATG, with stratification according to center and risk of disease. RESULTS: After a median follow-up of 24 months, the cumulative incidence of chronic GVHD was 32.2% (95% confidence interval [CI], 22.1 to 46.7) in the ATG group and 68.7% (95% CI, 58.4 to 80.7) in the non-ATG group (P<0.001). The rate of 2-year relapse-free survival was similar in the ATG group and the non-ATG group (59.4% [95% CI, 47.8 to 69.2] and 64.6% [95% CI, 50.9 to 75.3], respectively; P=0.21), as was the rate of overall survival (74.1% [95% CI, 62.7 to 82.5] and 77.9% [95% CI, 66.1 to 86.1], respectively; P=0.46). There were no significant between-group differences in the rates of relapse, infectious complications, acute GVHD, or adverse events. The rate of a composite end point of chronic GVHD-free and relapse-free survival at 2 years was significantly higher in the ATG group than in the non-ATG group (36.6% vs. 16.8%, P=0.005). CONCLUSIONS: The inclusion of ATG resulted in a significantly lower rate of chronic GVHD after allogeneic transplantation than the rate without ATG. The survival rate was similar in the two groups, but the rate of a composite end point of chronic GVHD-free survival and relapse-free survival was higher with ATG.

Dynamics and Diagnostic Relevance of Kynurenine Serum Level after Kidney Transplantation.

BACKGROUND: Inflammatory events after kidney transplantation (Tx) may lead to activation of the tryptophane-catabolizing enzyme indoleamine 2,3-dioxygenase followed by the formation of kynurenine (KYN). Post-transplant KYN serum levels in kidney allograft recipients were analyzed for their diagnostic value. MATERIAL AND METHODS: This was a retrospective analysis of KYN levels (normal value: 2.7±0.6 nmol/ml) measured in 4083 blood samples collected from 355 kidney graft recipients in connection with uncomplicated courses, acute rejections (ARs), infections, and type of immunosuppression. We performed descriptive data analysis and analysis of variance. RESULTS: In 212 recipients with immediately functioning grafts, the KYN levels dropped from pre-Tx 13.3±5.9 nmol/ml to nearly normal values at day 5 (5.8±3.0 nmol/ml). In patients with delayed graft function, the KYN reduction started only after the last hemodialysis treatment. With respect to ARs in recipients with creatinine values <300 µmol/l pre-AR, the increase of KYN levels depended on the severity of ARs (steroid-sensitive ARs: from 4.5±1.4 to 6.0±6.1 nmol/ml; steroid-resistant ARs: from 6.1±3.1 to 12.9±7.1 nmol/ml; vascular rejections: from 5.8±3.0 to 16.9±9.1 nmol/ml). In patients with creatinine values ≥300 µmol/l pre-AR, a further increase of the KYN level (from 10.1 to 13.2 nmol/ml) was only observed in severe, steroid-resistant ARs. With respect to infections evaluated, the KYN levels before diagnosis/start of treatment were 5.7±3.4 nmol/ml in asymptomatic CMV infections, 7.5±4.4 nmol/ml in CMV diseases, 8.3±3.3 nmol/ml in pneumonia, and 10.4±6.5 nmol/ml in bacterial sepsis. CONCLUSIONS: Serum KYN seems to be a reliable diagnostic tool for the assessment of post-transplant inflammatory complications, already in an early stage, and for monitoring the efficacy of therapeutic interventions. Prospective studies are recommended.

Causes and prognostic value of pre-transplant elevated kynurenine level in kidney allograft recipients.

BACKGROUND: The activation of the tryptophane catabolizing enzyme Indoleamine 2,3-dioxygenase leads to the formation of kynurenine and other metabolites that counter-regulate immune activation resulting in restoration of immune homeostasis. But in chronic immune activation, as in hemodialysed patients, the immunosuppressive feedback mechanisms continue as indicated by elevated kynurenine concentrations. However, its relevance is still a matter of debate. MATERIAL/METHODS: This retrospective analysis presents the pre-transplant kynurenine levels (quantified photometrically) of 307 kidney graft recipients in connection with some pre- and post-transplant variables and the type of immunosuppression (cyclosporine-based triple drug therapy without/with ATG-Fresenius-induction). Statistical analyses performed were analysis of variance, Scheffé's test for pairwise comparisons, Cox regression, Spearman's rank correlation, and extended segmentation analysis. RESULTS: The pre-transplant kynurenine level was significantly elevated as compared to healthy adults (14.1±5.9 vs. 2.7±0.6 nmol/ml, p<0.0001), significantly higher in PRA positive than in PRA negative patients (16.1 vs. 12.9 nmol/ml, p<0.001) and, supporting this observation, also higher (p<0.0001) in a cohort with predominant (89.7%) pre-sensitized patients (16.4±6.4 nmol/ml) having the longest time on the waiting list (median 39 months) as compared to cohorts with fewer (16.8-22%) pre-sensitized patients (12.7±4.4 resp. 13.4±5.8 nmol/ml) having shorter times on the waiting list (16-24 months). Patients with immediately functioning grafts showed a lower pre-transplant kynurenine level than patients with non-immediately functioning grafts (13.5±6.0 vs. 14.9±5.7 nmol/ml, p=0.053). No associations were found with basic diseases, rejections, or graft survival. CONCLUSIONS: The pre-transplant elevated serum kynurenine levels were highly associated with the patient's pre-sensitization status and their longer time on hemodialysis treatments, but did not allow prognostic assessments.

High graft protection and low incidences of infections, malignancies and other adverse effects with intra-operative high dose ATG-induction: a single centre cohort study of 760 cases.

BACKGROUND: In 1990 we introduced the intra-operative single high-dose induction (HDI) with ATG-Fresenius as a novel renal sparing concept. The aim of this analysis was to compare both the long-term patient and graft survival and the incidences of adverse effects in recipients treated with standard triple-drug therapy (TDT) alone or with an additional HDI with ATG-F. MATERIAL AND METHODS: A total of 760 renal transplant recipients receiving either TDT, consisting of steroids, azathioprine and cyclosporine (n=238) or TDT + 9mg/kg ATG-F intra-operatively (n=522) were included in this retrospective analysis. RESULTS: Compared to the TDT cohort the graft and patient survival over the entire ten year period was significantly prolonged in the TDT+HDI cohort. In contrast, main adverse effects (TDT+HDI vs. TDT) such as malignancies (4.4 vs. 2.1%), PTLD (0.4 vs. 0.4%), CMV diseases (18.6 vs. 15.5%), Herpes zoster infections (2.9 vs. 1.3%), bacterial pneumonias (3.1 vs. 1.3%) and post-operative thrombocytopenia <50×10³/µl (0.5 vs. 1.3%) did not significantly differ between the two immunosuppressive regimens. Only CMV-IgM seroconversions occurred significantly more in the HDI cohort (39.3 vs. 23.5%). The absolute numbers of CD3, CD4 and CD8 cell counts were significantly reduced in TDT+ATG-F HDI cohort only over a time period of about five days. CONCLUSIONS: This world-wide largest single-centre cohort analysis clearly shows the superiority of the HDI with ATG-F compared to TDT alone in improving long-term graft survival without increasing the risk for infections, malignancies or other adverse effects.

Efficacy and safety of adjunctive local moxifloxacin delivery in the treatment of periodontitis.

BACKGROUND: Moxifloxacin exerts excellent antibacterial activity against most putative periodontal pathogens and has been shown to kill bacteria in biofilm and host cells. METHODS: Patients with chronic periodontitis were randomly assigned to receive a single subgingival application of a 0.125%, 0.4%, or 1.25% moxifloxacin gel or placebo gel immediately after full-mouth scaling and root planing (SRP). Clinical efficacy measurements were assessed in sites with baseline probing depth (PD) of ≥5.4 mm at 6 weeks and 3 months and any adverse events were determined. In addition, putative periodontal pathogens and resistance of subgingival bacteria against moxifloxacin were assessed. RESULTS: Data of 57 patients were included in the statistical analysis. In all treatment groups, the PD decreased from baseline to 3 months, with the greatest reduction seen in patients treated with moxifloxacin 0.4% (1.5 ± 0.6 mm; P = 0.023 compared to placebo), followed by patients receiving moxifloxacin 1.25% (1.2 ± 0.4), moxifloxacin 0.125% (1.1 ± 1.1), and placebo (1.0 ± 0.6). No linear trend for PD reduction with increasing moxifloxacin concentrations was found. Porphyromonas gingivalis showed the greatest reduction in prevalence among the assessed pathogens, without any significant intergroup differences. No correlation or systematic relationship between adverse events, including bacterial resistance against moxifloxacin, and the investigational gels was found. CONCLUSIONS: In periodontal pockets with PD of ≥5.4 mm, a single subgingival administration of a 0.4% moxifloxacin gel as an adjunct to SRP may result in additional PD reduction compared to SRP alone. In addition, the investigated moxifloxacin gels seem to be safe.

Factors impacting short and long-term kidney graft survival: modification by single intra-operative -high-dose induction with ATG-Fresenius.

BACKGROUND: A majority of recipients benefited from the intra-operative single high-dose induction (HDI) with ATG-Fresenius (ATG-F) still leaving a group of recipients who did not profit from this kind of induction. Therefore the aim of this retrospective analysis was 1st to identify the risk factors impacting short and long-term graft survival, and 2nd to assess the efficacy of this type of induction in kidney graft recipients with or without these risk factors. MATERIAL/METHODS: A total of 606 recipients receiving two different immunosuppressive treatment regimens (1st: Triple drug therapy [TDT, n=196] consisting mainly of steroids, azathioprine and cyclosporine; 2nd: TDT + 9 mg/kg ATG-F intra-operatively [HDI, n=410]) were included in this analysis and grouped according to their kidney graft survival time (short GST: ≤1 yr, n=100 and long GST: >5 yrs, n=506). RESULTS: The main risk factors associated with a shortened graft survival were pre-transplant sensitization, re-transplantation, rejections (in particular vascular or mixed ones) and the necessity of a long-term anti-rejection therapy. Adding ATG-F single high dose induction to TDT was more efficient in prolonging kidney graft survival than TDT alone not only in recipients without any risk factors (p<0.005) but also in recipients with at least one risk factor (p<0.021). Only in 4.6% of recipients having two or more risk factors this effect could not be demonstrated. CONCLUSIONS: The intra-operative single high-dose induction with ATG-F significantly improves the kidney graft survival in recipients with or without risk factors and can therefore be recommended.

Supplementation of polyunsaturated fatty acids, magnesium and zinc in children seeking medical advice for attention-deficit/hyperactivity problems - an observational cohort study.

BACKGROUND: Polyunsaturated fatty acids are essential nutrients for humans. They are structural and functional components of cell membranes and pre-stages of the hormonally and immunologically active eicosanoids. Recent discoveries have shown that the long-chained omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) also play an important role in the central nervous system. They are essential for normal brain functioning including attention and other neuropsychological skills. MATERIALS AND METHODS: In our large observational study we monitored 810 children from 5 to 12 years of age referred for medical help and recommended for consuming polyunsaturated fatty acids (PUFA) in combination with zinc and magnesium by a physician over a period of at least 3 months. The food supplement ESPRICO® (further on referred to as the food supplement) is developed on the basis of current nutritional science and containing a combination of omega-3 and omega-6 fatty acids as well as magnesium and zinc. Study objective was to evaluate the nutritional effects of the PUFA-zinc-magnesium combination on symptoms of attention deficit, impulsivity, and hyperactivity as well as on emotional problems and sleep related parameters. Assessment was performed by internationally standardised evaluation scales, i.e. SNAP-IV and SDQ. Tolerance (adverse events) and acceptance (compliance) of the dietary therapy were documented. RESULTS: After 12 weeks of consumption of a combination of omega-3 and omega-6 fatty acids as well as magnesium and zinc most subjects showed a considerable reduction in symptoms of attention deficit and hyperactivity/impulsivity assessed by SNAP-IV. Further, the assessment by SDQ revealed fewer emotional problems at the end of the study period compared to baseline and also sleeping disorders. Mainly problems to fall asleep, decreased during the 12 week nutritional therapy. Regarding safety, no serious adverse events occurred. A total of 16 adverse events with a possible causal relationship to the study medication were reported by 14 children (1.7%) and only 5.2% of the children discontinued the study due to acceptance problems. Continuation of consumption of the food supplement was recommended by the paediatricians for 61.1% of the children. CONCLUSION: Our results suggest a beneficial effect of a combination of omega-3 and omega-6 fatty acids as well as magnesium and zinc consumption on attentional, behavioural, and emotional problems of children and adolescents. Thus, considering the behavioural benefit in combination with the low risk due to a good safety profile, the dietary supplementation with PUFA in combination with zinc and magnesium can be recommended.

Improved long-term survival after intra-operative single high-dose ATG-Fresenius induction in renal transplantation: a single centre experience.

BACKGROUND: In organ grafts donor-specific sensitization is initiated immediately after revascularization. Therefore, in 1990 we introduced the intra-operative single high-dose ATG-Fresenius (ATG-F) induction in addition to standard triple drug therapy (TDT) consisting of steroids, azathioprine and cyclosporin. A total of 778 first renal transplantations from deceased donors, performed between 1987 and 1998, were included in this evaluation. MATERIAL/METHODS: This retrospective analysis of clinic records and electronic databases presents data of all recipients of first kidney grafts who received two different ATG-F inductions (1(st) group: 9 mg/kg body weight as single high-dose intra-operatively, n=484; 2(nd) group: 3 mg/kg body weight on 7 or 8 consecutive days as multiple-dose starting also intra-operatively, n=78) and standard TDT alone (3(rd) group: TDT alone, n=216). RESULTS: The 10-year patient survival rates were 72.6+/-2.6% (TDT + ATG-F single high-dose), 79.5+/-5.1% (TDT + ATG-F multiple-dose) and 67.2+/-3.7%% (TDT alone; Kaplan-Meier estimates with standard errors; ATG-F vs TDT alone, p=0.001). The 10-year graft survival rates with censoring of patients that died with a functioning graft were 73.8+/-2.4%, 57.7+/-5.8% and 58.4+/-3.6% (Kaplan-Meier estimates with standard errors; 1(st) vs 2(nd )and 3(rd) group, respectively, p<0.001) and the 10-year graft survival rates with patient death counted as graft failure were 58.3+/-2.7%, 55.7+/-5.8% and 48.2+/-3.5% (Kaplan-Meier estimates with standard errors; ATG-F single high-dose vs TDT, p=0.023). In pre-sensitized recipients there were also significant differences in favour of ATG-F, more notably in the single high-dose ATG-F induction. A total of 69% of the patients in the two cohorts receiving ATG-F did not experience any transplant rejections compared to 56% in patients undergoing TDT alone (p=0.018). The incidence of infectious complications was comparable across all groups. CONCLUSIONS: According to evidence obtained from the routine documentation of 778 renal transplantations, ATG-F induction therapy administered as a part of immunosuppressive therapy significantly improves patient survival and reduces the risk of graft failure and transplant rejections.

The influence of sulthiame on EEG in children with benign childhood epilepsy with centrotemporal spikes (BECTS).

PURPOSE: To evaluate the effects of sulthiame (Ospolot; STM) monotherapy compared with placebo on the EEG in children with benign childhood epilepsy with centrotemporal spikes (BECTS). METHODS: Sixty-six patients (aged 3-11 years) entered a 6-month double-blind trial and were randomized to either STM (n = 31) or placebo (n = 35). Clinical data and general results have been reported elsewhere (1). One-hundred seventy-nine sleep EEGs were recorded at screening and after 4 weeks, 3 months, and 6 months. EEGs were analyzed by a blind reviewer using a standard protocol for each EEG. This standard protocol collected data on general changes, specific epileptiform, and nonspecific focal and generalized changes. A classification system was defined depending on rating of pathologic EEG changes. Because of the higher number of treatment-failure events (i.e., seizures) in the placebo group, there was an increasing imbalance between the two groups regarding the number of recorded sleep EEGs over time (STM, 104; placebo, 74). A Wilcoxon-Mann-Whitney U test was used to describe differences in the grade of pathology during individual follow-up between the two groups. RESULTS: The sleep-EEG was found to be normalized in 21 patients treated with STM (12/21 transient) and in five patients treated with placebo (4/5 transient). In the STM group, the EEG showed a marked improvement during intraindividual course when comparing the classification of follow-up EEGs at each time point with the screening EEG. Comparable improvements were not observed in the placebo group (exact two-tailed p value at 4 weeks, p < 0.0001; at 3 months, p = 0.0010; and at 6 months, p < 0.0001). CONCLUSIONS: STM had marked effects on the EEG in BECTS, which led to normalization in the majority of the patients. Most of those whose EEGs were not normalized showed improvement in the grade of EEG pathology. Normalization persisted in >50% of patients during the investigation. Spontaneous normalization in the placebo group reflects the wide spectrum of individual courses, which must be considered when analyzing drug effects on EEG in BECTS.

A prospective randomized controlled study on the efficacy and tolerance of two antilymphocytic globulins in the prevention of rejection in first-heart transplant recipients.

The usefulness of induction phase treatment in heart transplantation is a long-standing debate in the literature. Several centers report good short-term survival without such treatment, but no randomized trial addresses this question. If induction treatment is to be used, most centers prefer rabbit polyclonal antisera to OKT3. However, again, no randomized trial has compared the relative efficacy and tolerance of rabbit antisera. Fifty first-heart transplant recipients with standard triple immunosuppression were randomized to receive ATG Fresenius ( n=24) or Thymoglobulin Mérieux ( n=26) as an induction treatment and were followed for 1 year. The two groups were well matched for gender, age, pre-transplant diagnosis and ischemia time. Actuarial survival at 1 year was 87.5% in the Fresenius group and 84.6% in the Mérieux group (Fisher's exact test; P=1). The average number of rejection episodes per patient was comparable in both treatment groups (Fresenius: mean=2.63, SD=1.44; Mérieux: mean=2.46, SD=2.04). Mean time to first rejection was 48.9+/-37.2 days in the Fresenius group versus 59.6+/-54 days in the Mérieux group (Mann-Witney U-test: z=0.77; P=NS). The total number of rejections across all patients was also comparable (Fresenius: 63; Mérieux: 64) as well as the severity of rejection (seven moderate rejections out of a total of 63 in the Fresenius group and eight out of 64 in the Mérieux group). Eighteen Fresenius (75%) and 15 Mérieux (58%) patients suffered from at least one infection ( P=NS). The tolerance to treatment was excellent in both groups. Total lymphocyte count and all subsets of tested lymphocytes decreased rapidly after the introduction of either antiserum but was more pronounced and persisted for longer in the Mérieux group. ATG Fresenius or Thymoglobulin Mérieux as induction treatments in first-heart transplant recipients treated with standard immunosuppression have the same relative efficacy with regard to survival, acute rejection or infection rate, and are well tolerated.
