Due to complex comorbidity, high infectious complication rates, an elevated risk of relapsing for primary renal disease, as well as inferior recipient and allograft survivals, individuals with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAVs) are often considered as poor transplant candidates. Although several aspects of recurrent and de novo AAVs remain unclear, recent evidence suggests that kidney transplantation (KT) represents the best option, which is also the case for this particular subgroup of patients. Special counselling and individualized approaches are strongly recommended at the time of enlistment and during the entire post-transplant follow-up. Current strategies include avoiding transplantation within one year of complete clinical remission and thoroughly assessing the recipient for early signs of renal or systemic vasculitis. The main clinical manifestations of allograft AAV are impaired kidney function, proteinuria, and hematuria with ANCA positivity in most cases. Mixed results have been obtained using high-dose steroids, mycophenolate mofetil, or cyclophosphamide. The aim of the present review was to summarize the available literature on AAVs in KT, particularly focusing on de novo pauci-immune glomerulonephritis.

Collapsing glomerulopathy (CG) is a variant of focal segmental glomerulosclerosis (FSGS) characterized histologically by prominent glomerular capillary tuft collapse with hypertrophy and hyperplasia of podocytes and tubulointerstitial damage. Patients usually present with heavy proteinuria and rapidly progressive renal failure. We report a patient who developed de novo CG with severe clinical manifestations including worsening renal failure and nephrotic syndrome within six months of receiving deceased donor kidney transplant. Secondary work-up was negative, and despite therapy with high-dose steroids and plasmapheresis, allograft function rapidly deteriorated with the need for dialysis. Theories about the pathogenesis of this entity as well as treatment modalities are discussed.

Thirty-eight patients whose primary extremity or limb girdle osteosarcomas had been completely excised (37 amputations, one limb sparing procedure) were allocated at random to two treatment groups receiving respectively regular follow-up examinations plus a high-dose methotrexate (HDMTX) regimen or regular follow-up without primary adjuvant chemotherapy. Although the vincristine, HDMTX, leucovorin regimen was generally quite tolerable when given at three-week intervals for one year and most of the chemotherapy patients followed the planned HDMTX dose escalations from 3 to 6 to 7.5 g/m2, delayed methotrexate excretion limited dosage escalations in 25%. An estimated 52% of the 38 patients were surviving five years after randomization and an estimated 42% remained continuously relapse-free after five years. No significant differences between the outcomes of the 20 treated and the 18 untreated patients were apparent; however, power to detect differences was low. Furthermore, no significant differences in postmetastasis survival were apparent between the 12 treated and 10 untreated patients who relapsed. Approximately 20% of these failing patients appear to have been salvaged for long-term survival. This pilot study of HDMTX confirms the continuing need for controlled clinical trials in determining the therapeutic value of adjuvant chemotherapy programs for patients with primary osteosarcoma.

Prospective Longitudinal

Systemic sclerosis (SSc) is a collagen-vascular disorder characterized by fibrosis and vasculopathy. Delta finger to palm distance (delta FTP) is an index measuring the distance between the tip of the third finger to the distal palmar crease in the flexed and extended position. The present study aimed to evaluate the clinical value of delta FTP and to assess the correlation of delta FTP with modified Rodnan skin score (mRSS) and forced vital capacity (FVC) over the 12-month follow-up. This prospective longitudinal study began with 50 participants who were followed for twelve months. Lowess smoothing and linear regression were applied to detect and assess the relationship between delta FTP and mRSS. p-values were adjusted by the Benjamini-Hochberg method (BHM) as a control for false discovery rate. Delta FTP was lower among patients with higher disease duration (p-valueadj: 0.008), diffuse cutaneous SSc (p-valueadj: 0.006), digital ulcers (p-valueadj: 0.003), telangiectasia (p-valueadj: 0.006) and dysphagia (p-valueadj: 0.036). The mRSS has a significant negative linear effect on the delta FTP at the baseline and the end of the follow-up (r: -0.31 and -0.40, respectively). Moreover, changes of mRSS and delta FTP showed a negative linear association over time (r: -0.22). These linear effects remained significant after regrouping the patients based on their SSc subtype. Delta FTP and FVC were not correlated either at the baseline or at the end. It seems that the delta FTP can be a valuable clinical index, supported by its correlated changes with mRSS and other SSc clinical manifestations over the one-year follow-up.

Abstract Background and Aims Survival of patients with Multiple Myeloma (MM), Light Chain Amyloidosis (LCA) and Monoclonal Gammopathies of renal significance (MGRS) on chronic renal replacement therapy (RRT) is poor. The gold standand treatment of plasma cell dyscrasias (PCD) is high-dose chemotherapy followed by Autologous Stem Cell Transplantation (ASCT) which can induce complete remission and longer survival than chemotherapy alone. Kidney transplantation (KT) after ASCT could represent an option for patients with PCD and End Stage Renal Disease (ESRD). There is no evidence about the time of follow up required from MM remission and KT. Method We present a case series of 5 patients who underwent KT after ASCT and remission of MM among 2,500 transplant recipients followed at the Nephrology Dialysis and Renal Transplantation Unit of S.Orsola University Hospital from 1967 untill now. As in case of recovery from solid cancers, the feasibility of KT after MM was considered when no signs of relapse were assessed. In our cohort 3 patients were affected by Light Chain Deposition Disease (LCDD), 1 patient presented Myeloma Cast Nephropathy (MCN) and one patient Light Chain Amyloidosis (LCA). They all required RRT and underwent KT after ASCT. Results Time between ASCT and KT ranged from 3 and 11 years and clinical outcome was very different. The mean follow up period ranged from 2 to 4 years. In the first case (LCDD) KT was performed 11 years after ASCT, the graft failure occurred 6 years later because of chronic allograft nephropathy requiring RRT. In the second case (LCDD) patient received KT 3 years after ASCT. He developed Bence-Jones proteinuria requiring specific therapy with Dexametasone and Bortezomib determining progressive graft failure. In the third case (LCDD) KT was performed 4 years after ASCT and the 4 year follow up is negative for relapse of MM or ESRD. The fourth patient presented MCN and received KT 8 years after ASCT. MCN relapsed 6 years later; it caused ESRD requiring RRT. In the last patient (LCA) KT was performed 4 years after ASCT. No recurrence occurred in a 2-year follow up. Conclusion MM is the most frequent malignancy in dialytic population; the need for KT in MM remains high. ASCT improves the quality of life and offers higher survival in patients with myeloma/MGRS/amyloidosis-related ESRD. Therefore the combination of chemotherapy/ASCT and KT is pivotal to pursue renal restoring. Since high risk of recurrence larger study are required to clarify the better follow up period after MM remission and KT.

Abstract CCG-2961 tested an intensively timed induction therapy consisting of cytarabine (AC), etoposide, thioguanine, dexamethasone, idarubicin and daunorubicin. Patients in remission after induction were randomized to a second induction course (Arm A) or a 3-drug combination of fludarabine, AC, and idarubicin (Arm B). Course 3 for patients with related donors was bone marrow transplantation (BMT); for those without donors, high dose AC/l-asparaginase. After Course 3 patients without donors were randomized to 14 infusions of Interleukin 2 (IL2) over 18 days or follow-up. CNS prophylaxis was intrathecal AC. Eligibility included all subtypes of de novo AML except acute promyelocytic leukemia and AML in patients with Down syndrome. CCG-2961 opened in Oct.1996 and closed in Dec. 2002. The DSMC suspended the study between Oct. 1999 and May 2000 while the 2961 Committee developed supportive care policies to reduce treatment-related mortality (TRM). CCG-2961 enrolled 900 de novo patients aged 3 days to 21 years, with 495 and 405 patients accruing pre-and post suspension respectively. Remission induction rate is 88.5%. With median follow-up of 3.6 years (range: 0 – 8.1 years), event-free survival (EFS) at 3 years is 44±3% and survival (OS) 57±3%. Disease-free survival (DFS) following Course 2 Arms A and B are not different, although relapse is significantly higher in Arm A (7.3% .vs. 3.1% P=0.018) and TRM more common in Arm B (7.9% vs.4.2% P=0.059), despite 7 less days of neutropenia in Arm B (P<0.001). DFS is 65±9% for patients with a donor versus 50±5% for patients without a donor (P=0.005); respective OS, 74±8% and 66±5% (P=0.221). However, among 98 patients in CR1 with t(8;21) or inv(16) cytogenetics, outcomes in those without and with a donor were no different: DFS (61±12% vs. 72±18%, P = 0.49) and OS (78±10% vs. 77±17%, l P= 0.85). DFS with and without IL2 is 55±9% and 60±8%(P=0.606). Outcomes improved progressively over time. EFS pre- and post-suspension are 41±4% and 47±5%(P=0.038); OS, 52±5% and 63±5%(P=0.005); TRM is 17±3% pre- and 12±3% post-suspension (P=0.039). Factors predictive of inferior EFS are age >17 years, Afro-American and Hispanic ethnicity, body mass index <10th or >95th percentile for age, absence of related marrow donor, WBC > 50,000/mm3, karyotype with −7/7q, −5/5q- or > cytogenetic 5 abnormalities, FLT3/ITD, >15 % morphologic blasts on day 14 or >0.5% immunologically detectable blasts at the end of induction. CCG-2961 confirms the efficacy and high TRM of intensively timed therapy. Neither fludarabine nor IL2 increases DFS or OS, and availability of a donor does not improve outcomes in those with favorable cytogenetics.

Abstract Background: In children with ALL, current chemotherapy regimens produce an event-free survival (EFS) of greater than 80%. Adults with ALL have a much poorer prognosis, with EFS rates of 30–40%. Recent retrospective studies suggest that young adult patients may have superior outcomes when treated on more intensive pediatric regimens, but prospective studies are lacking. A phase II trial was performed in an effort to determine if an intensive pediatric regimen can be administered to adults with ALL. Methods: The therapeutic backbone of this protocol is based upon the high-risk arm of the DFCI Childhood ALL Consortium Protocol 00–01. Patients with newly diagnosed ALL were enrolled and received intensive multiagent remission induction chemotherapy, which included doxorubicin, prednisone, vincristine, high-dose methotrexate, high-dose asparaginase, and triple intrathecal therapy. CNS prophylaxis included triple intrathecal therapy and cranial radiation. Intensification therapy consisted of 3 week courses of doxorubicin, vincristine, dexamethasone, 6-mercaptopurine and 30 weeks of high-dose asparaginase that was individually dosed in order to maintain asparagine depletion. Continuation therapy consisted of 3 week courses of vincristine, dexamethasone, methotrexate and 6-mercaptopurine for a total of 2 years from an established complete remission (CR). Results: 71 patients have been enrolled to date. Although there was no initial upper age restriction, the protocol was amended to include only patients between the ages of 18–50 with de novo ALL; this amendment excluded 4 patients from the analysis. Two patients were enrolled but never received therapy. Demographic data are available for 61 evaluable patients. The median age was 28 years, (range, 18–50), 65% were male, 75% had B-lineage phenotype, and 13% were Philadelphia chromosome positive. In the 54 patients for whom response data was available, the 4 week CR rate was 82%. Among the patients who had the opportunity to complete Intensification therapy, asparaginase data was available for 23 patients, 18 (78%) of whom completed all 30 weeks. One death occurred during induction therapy from sepsis. Four patients developed grade 3 pancreatitis and one patient died of grade 5 pancreatitis. The latter case represented the only remission death on study. There were two cases of osteonecrosis, 10 cases of thrombosis/embolism and 12 cases of neutropenic infection that occurred during the post-remission period. At the median follow-up time of 18.4 months, the estimated EFS is 75% (95%CI: 61–89%) and the overall survival is 79% (95%CI: 65–93%). Conclusions: These results suggest that administration of a dose intensified pediatric-like strategy is feasible. Although the high EFS rate requires longer follow up and larger confirmatory studies, such intensive treatment of young adults with ALL could represent a major therapeutic advance.

Abstract The optimal induction regimen for patients with symptomatic myeloma who are eligible for transplantation is currently unknown. While thalidomide and dexamethasone is an effective regimen, it only has a 60 to 65% response rate and few complete responses (CR). Bortezomib based inductions have demonstrated a high response rate and an improved CR as well. Recently the IFM reported the initial results of the randomized bortezomib plus dexamethasone versus VAD induction followed by transplant, which demonstrated that fewer patients treated with bortezomib required tandem transplants. Wang et al reported a high induction response rate with the combination of BTD for only 2 cycles given over a 28 day cycle. Here we report our experience with the combination of BTD as induction therapy. 38 patients with symptomatic myeloma were treated with BTD as induction therapy. Patients received standard dose and schedule bortezomib at 1.3 mg/m2 on days 1, 4, 8, and 11 with thalidomide at 100 mg/day, and 8 days of 40 mg dexamethasone every 21 days. The median age was 58 years (38–70) with 19 males. This was first line therapy for 29 patients, second line for 7 patients and 3rd line for 2. 12 patients had ISS stage 2 and 8 had ISS stage 3. The median β2M was 3.4 (1.66–41.89). Median creatinine was 1.1 (0.6–21.0). Nineteen patients had an IgG paraprotein, 6 an IgA, and 16 patients had light chain disease. The median number of cycles administered was 4 (2–8). Fifteen patients developed neuropathy of any grade. One patient developed grade 3 neuropathy. The overall response rate (CR, VGPR, plus PR) was 92%, with 58% of patients achieving a VGPR or better, and 21% of patients achieving an immunofixation negative CR. 1 patient had a minimal response and 2 patients had progressive disease (both patients presented with plasma cell leukemia). These two patients were treated with the combination of BTD with PACE chemotherapy. One of the two died from progressive disease and the other patient remains in complete remission after high dose therapy and autologous transplantation. 29 patients had consolidation therapy with high dose melphalan and autologous peripheral blood stem cell transplantation. Eight patients have collected stem cells without proceeding with immediate consolidation therapy. After a median follow up of 373 days, median progression free survival and overall survival have not been reached. One year overall survival is 97%. One year progression free survival is 87%. In conclusion, we report a very high response rate with a short course of bortezomib, thalidomide and dexamethasone with an acceptable toxicity profile. Follow up of patients in CR treated without high dose therapy and autologous transplant is in progress. Further studies of this active regimen are warranted.

In contrast, adults with ALL have a much poorer prognosis, with EFS rates of 30–40%. Recent retrospective studies suggest that young adults may have superior outcomes when treated with intensive pediatric regimens. Unfortunately, prospective studies are lacking. This phase II trial was performed to determine if an intensive pediatric regimen could be administered to adults with ALL. Methods: The therapeutic backbone of this protocol is based on the high-risk arm of the DFCI Childhood ALL Consortium Protocol 00-01. Patients with newly diagnosed ALL received induction chemotherapy, which included doxorubicin, prednisone, vincristine, high-dose methotrexate, L-asparaginase (L-asp), and triple intrathecal therapy. CNS prophylaxis included triple intrathecal therapy and cranial radiation. Intensification therapy consisted of ten 3-week courses of doxorubicin, vincristine, dexamethasone, 6-mercaptopurine and 30 weeks of L-asp that was dosed to maintain asparagine depletion, defined as an L-asp level between 0.1 and 0.14. Continuation therapy consisted of 3 week courses of vincristine, dexamethasone, methotrexate and 6-mercaptopurine for a total of 2 years from an established complete remission (CR). Results: 89 patients have been enrolled and treated to date. The first 75 eligible patients were used for this analysis, 73 of whom had on-study data. Although there was no initial upper age restriction, the protocol was amended to include only patients between the ages of 18–50 with de novo ALL, which excluded 4 patients from the analysis. The median age was 28 years, (range, 18–50), 60% were male, 74% had B-lineage phenotype, and 20% were Philadelphia chromosome positive. The CR rate after 4 weeks was 84%. 39 patients had the opportunity to complete L-asp intensification therapy, and 27 (69%) completed all 30 weeks. The median L-asp dose was 16,582 U/m2 (starting dose was 12,500 U/m2). One death occurred during induction therapy (sepsis). Nine patients developed pancreatitis, one of whom died. This last case represented the only remission death on study. Two patients developed osteonecrosis, 14 thrombosis/embolism and 23 neutropenic infection during the post-remission period. With a median follow-up time of 15.3 months, the estimated 2-yr EFS is 72.5% (95%CI: 61–84%) and the estimated 2-yr overall survival (OS) is 77.1% (95%CI: 67–95%). Conclusions: The administration of a dose intensified pediatric regimen to adults with ALL is feasible. Although the high EFS and OS rates require longer follow up, such intensive treatment strategies for young adults with ALL could represent a major therapeutic advance.
