RESUMO

Case of a patient with acute myeloid leukemia (AML) positive for mutations in both genes NPM1 and FLT3-ITD who underwent two allogeneic haematopoietic stem cell transplants (HSCT); the second allograft one was followed by extramedullary relapse (granulocytic sarcoma of right breast), with blast cells positive for FLT3-ITDmutation.  Treatment with Gilteritinib, a second generation selective oral type I FLT3 inhibitor, was started after the second HSCT with complete regression of breast granulocytic sarcoma in absence of hematological and extra hematologic toxicity. We conclude that Gilteritinib can represent an effective therapy for extra hematologic relapse, with acceptable toxicity and outpatient management.

RESUMO

Retinoic acid (RA) in association with chemotherapy or with arsenic trioxide (ATO) results in high cure rates of acute promyelocytic leukemia (APL). We show that RA-induced differentiation of human leukemic cell lines and primary blasts dramatically increases their sensitivity to endoplasmic reticulum (ER) stress-inducing drugs at doses that are not toxic in the absence of RA. In addition, we demonstrate that the PERK pathway, triggered in response to ER stress, has a major protective role. Moreover, low amounts of pharmacologically induced ER stress are sufficient to strongly increase ATO toxicity. Indeed, in the presence of ER stress, ATO efficiently induced apoptosis in RA-sensitive and RA-resistant APL cell lines, at doses ineffective in the absence of ER stress. Our findings identify the ER stress-related pathways as potential targets in the search for novel therapeutic strategies in AML.

RESUMO

OBJECTIVES: Thrombocytopenia is a hallmark for patients with cirrhosis and it is perceived as a risk factor for bleeding events. However, the relationship between platelet count and bleeding is still unclear. METHODS: We investigated the relationship between platelet count and major or clinical relevant nonmajor bleedings during a follow-up of ∼4 years. RESULTS: A total of 280 cirrhotic patients with different degrees of liver disease (67% males; age 64±37 years; 47% Child-Pugh B and C) were followed up for a median of 1,129 (interquartile range: 800-1,498) days yielding 953.12 patient-year of observation. The annual rate of any significant bleeding was 5.45%/year (3.57%/year and 1.89%/year for major and minor bleeding, respectively). Fifty-two (18.6%) patients experienced a major (n=34) or minor (n=18) bleeding event, predominantly from gastrointestinal origin. Platelet counts progressively decreased with the worsening of liver disease and were similar in patients with or without major or minor bleeding: a platelet count ≤50 × 103/µl was detected in 3 (6%) patients with and in 20 (9%) patients without any bleeding event. Conversely, prothrombin time-international normalized ratio was slightly higher in patients with overall or major bleeding. On Cox proportional hazard analysis, only a previous gastrointestinal bleeding (hazard ratio (HR): 1.96; 95% confidence interval: 1.11-3.47; P=0.020) and encephalopathy (HR: 2.05; 95% confidence interval: 1.16-3.62; P=0.013) independently predicted overall bleeding events. CONCLUSIONS: Platelet count does not predict unprovoked major or minor bleeding in cirrhotic patients.

RESUMO

This research paper aims to investigate if oxidative stress biomarkers increase after a painful procedure in term newborns and if nonpharmacological approaches, or sex, influence pain degree, and the subsequent OS. 83 healthy term newborns were enrolled to receive 10% oral glucose or sensorial saturation (SS) for analgesia during heel prick (HP). The ABC scale was used to score the pain. Advanced oxidation protein products (AOPP) and total hydroperoxides (TH) as biomarkers of OS were measured at the beginning (early-sample) and at the end (late-sample) of HP. The early-sample/late-sample ratio for AOPP and TH was used to evaluate the increase in OS biomarkers after HP. Higher levels of both AOPP and TH ratio were observed in high degree pain (4-6) compared with low degree pain score (0-3) (AOPP: p = 0.049; TH: p = 0.001). Newborns receiving SS showed a significantly lower pain score (p = 0.000) and AOPP ratio levels (p = 0.021) than those without. Males showed higher TH levels at the end of HP (p = 0.005) compared to females. The current study demonstrates that a relationship between pain degree and OS exists in healthy full-term newborns. The amount of OS is gender related, being higher in males. SS reduces pain score together with pain-related OS in the newborns.

RESUMO

BACKGROUND: Even if the jejunoileal bypass has been definitely abandoned due to the high rate of hepatic complications, cases of liver injury after the new bariatric procedures are still reported. We aimed to review the available literature concerning liver damage associated with the older and newer types of bariatric surgeries. METHODS: An extensive literature search of MEDLINE was performed using different combinations of the following terms: "bariatric surgery OR biliopancreatic diversion OR jejunoileal bypass OR roux-en-y gastric bypass OR vertical banded gastroplasty OR laparoscopic adjustable gastric banding" AND "hepatic/liver damage OR hepatic/liver impairment OR hepatic/liver failure". RESULTS: Although weight loss after bariatric surgery frequently induces an improvement of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis, and even the regression of hepatic fibrosis, bariatric procedures have been also associated with cases of acute liver failure or of chronic liver disease evolving until cirrhosis. After the jejunoileal bypass has been definitely abandoned, most of the recently described cases concern biliopancreatic diversion with/without duodenal switch, but liver damage has been reported after almost all types of bariatric surgeries. Protein-calorie malnutrition, bacterial overgrowth, lipotoxicity and genetic background are likely to play a central role in the physiopathology of hepatic injury. CONCLUSIONS: Understanding the inner mechanisms underlying acute or chronic liver injury after bariatric surgery can help in the prevention, early recognition and treatment of these rare but concrete cases.

RESUMO

BACKGROUND: Platelet (PLT) gel has been successfully used in tissue regeneration of diabetic and surgical wounds through the releasing of growth factors such as basic fibroblast and PLT-derived growth factors. Based on this background, our previous clinical trial have assessed the feasibility and efficacy of PLT gel for the treatment of muco-cutaneous lesions related to graft versus host disease (GvHD) after allogeneic haematopoietic stem cell transplantion (HSCT). The promising results reported in a small series of 6 patients, of whom 1 with oral ulcers, represent the rationale of the present study. MATERIALS AND METHODS: The aim of this study was to verify the efficacy and safety of PLT gel for treating oral ulcers due to chronic GvHD. Allogeneic hemocomponents were used to obtain PLT gel with an automated system for the on-site preparation and application of patient (autologous) or healthy blood donor (allogeneic)-derived fibrin sealant or PLT-rich fibrin (Vivostat system, Vivostat A/S). Ten patients with multiple oral lesions related to chronic GvHD underwent allogeneic PLT gel as local therapy alone or in combination with systemic therapy in half of the cases. RESULTS: After the second PLT gel application, all patients resumed the feeding and a significant improvement of the oral pain was observed. After a median of five PLT gel applications (range, 2-15), 7 out of 10 patients showed a complete response. No side effects were documented. CONCLUSION: These data confirm that the PLT gel may be used as a safe and effective tool, alone or in combination with systemic therapy, for the treatment of mucosal lesions of mouth related to cGvHD.

RESUMO

OBJECTIVE: The aim of this prospective observational study was to identify local risk factors for the development of clinical manifestations of oral chronic Graft versus Host Disease (cGvHD) in a cohort of patients affected by haematological malignant diseases who underwent allogeneic haematopoietic stem cell transplantation (HSCT). MATERIALS AND METHODS: In the context of an active collaboration between the Rome Transplant Network of the Hematology and the Oral Pathology Division at "Policlinico Tor Vergata", in Rome, 47 haematological patients were included in this trial based on a systematic dental screening and follow-up protocol. The dental checks were planned 1 month before the transplant procedure while the subsequent follow ups were scheduled on day +100, +180, +365 and + 730 after the transplant. The tool used for the dental checks was a detailed report including all the potential oral features responsible of mechanical, chemical or infective injuries, except for the drugs. RESULTS: Overall, 64% of patients (N=30) did not perform dental hygiene during the screening pre-transplant and 53% (25/47) developed cGvHD with oral involvement. The most part of patients (84%) who experienced oral manifestations of cGvHD during the follow-up period after HSCT did not perform dental hygiene before the transplant procedure. Moreover, the comparison between the "presence" or "absence" of dental hygiene before the allogeneic HSCT showed a statistical significant increasing during the follow-up period in the occurrence of oral lesions due to the cGvHD for patients who lack pre-transplant dental care (p=0.029).On the contrary, the frequency of the other factors such as malocclusions, fractured teeth, incongruous prosthesis, food, smoke, alcol and bad habits, resulted similar between the group with or without typical oral lesions of cGvHD. CONCLUSIONS: The prevention of oral infectious complications provided by primary and secondary dental cares can result in a great benefit for haematological patients who underwent allogeneic HSCT. The combined hematological and dental management represents a clinical need before and after allogeneic HSCT for the removal of inconvenient issues with impact on the short and long-term outcome. Poor dental hygiene seems to be a local risk factor for the development of oral lesions due to cGvHD. However, a larger cohort of patients is necessary to confirm these preliminary data and to evaluate the best preventive and therapeutic oral hygiene protocol in this specific setting.

RESUMO

The overall rate of hepatitis B virus (HBV) reactivation was evaluated in a population of 373 haematological stem cell transplant (HSCT) patients treated with lamivudine (LMV) if they were anti-HBc-positive/HBV-DNA-negative recipients or if they were HBV-negative recipients with an anti-HBc-positive donor. The incidence of HBV reactivation was calculated in two groups of autologous (auto) or allogeneic (allo) HSCT patients who were stratified according to their HBV serostatus. The former group included 57 cases: 10 auto-HSCT and 27 allo-HSCT anti-HBc-positive recipients, two auto-HSCT and three allo-HSCT inactive carriers, and 15 allo-HSCT recipients with an anti-HBc-positive donor. Forty-seven (82.4%) patients in this group received LMV prophylaxis (the median (interquartile range, IQR) of LMV treatment was 30 (20-38) months). The second group consisted of 320 anti-HBc-negative auto-HSCT and allo-HSCT recipients with anti-HBc-negative donors. None of these patients received any prophylaxis. Two patients in the first group and two in the second group experienced reactivation of HBV infection, with an incidence of 3.5% (95% CI 0.4-12.1%) and 0.6% (95% CI 0.1-2.2%), respectively. Only one out of four reactivated patients was LMV-treated. The cumulative probability of HBV reactivation at 6 years from HSCT was 15.8% (95% CI 15.2-16.4%). Three of four viral isolates obtained from the HBV-reactivated patients harboured mutations in the immune-active HBsAg-region. In a HSCT population carefully evaluated for HBV prophylaxis, a risk of HBV reactivation persisted in the group of patients who were not LMV-treated. Only one LMV-treated patient experienced reactivation of HBV with a resistant HBV isolate.

RESUMO

OBJECTIVE: There is considerable uncertainty about whether depression screening programs in primary care may improve outcomes and what specific features of such programs may contribute to success. We tested the effectiveness of a program involving substantial commitment from local mental health services. METHODS: Prospective, randomised, patient- and evaluator-masked, parallel-group, controlled study. Participants were recruited in several urban primary care practices where they completed the PC-SAD screener and WHOQOL-Bref. Those who screened positive and did not report suicidal ideation (N=115) were randomised to an intervention group (communication of the result and offer of psychiatric evaluation and treatment free of charge; N=56) or a control group (no feedback on test result for 3 months; N=59). After 3 months, 100 patients agreed to a follow-up telephone interview including the administration of the PC-SAD5 and WHOQOL-Bref. RESULTS: Depression severity and quality of life improved significantly in both groups. Intent-to-treat analysis showed no effect of the intervention. As only 37% of patients randomised to the intervention group actually contacted the study outpatient clinic, we performed a per-protocol analysis to determine whether the intervention, if delivered as planned, had been effective. This analysis revealed a significant positive effect of the intervention on severity of depressive symptoms, and on response and remission rate. Complier average causal effect analysis yielded similar results. CONCLUSION: Due to the relatively small sample size, our findings should be regarded as preliminary and have limited generalizability. They suggest that there are considerable barriers on the part of many patients to the implementation of depression screening programs in primary care. While such programs can be effective, they should be designed based on the understanding of patients' perspectives.

RESUMO

Ninety-seven patients affected by high-risk hematological malignancies underwent G-CSF primed, unmanipulated bone marrow (BM) transplantation from a related, haploidentical donor. All patients were prepared with an identical conditioning regimen including Thiotepa, Busilvex, Fludarabine (TBF) and antithymocyte globulin given at myeloablative (MAC = 68) or reduced (reduced intensity conditioning (RIC) = 29) dose intensity and received the same GvHD prophylaxis consisting of the combination of methotrexate, cyclosporine, mycofenolate-mofetil and basiliximab. Patients were transplanted in 1st or 2nd CR (early phase: n = 60) or in > 2nd CR or active disease (advanced phase: n = 37). With a median time of 21 days (range 12-38 days), the cumulative incidence (CI) of neutrophil engraftment was 94 ± 3%. The 100-day CI of III-IV grade acute GvHD and the 2-year CI of extensive chronic GvHD were 9 ± 3% and 12 ± 4%, respectively. Overall, at a median follow-up of 2.2 years (range 0.3-5.6), 44 out of 97 (45%) patients are alive in CR. The 5-year probability of overall survival (OS) and disease-free survival (DFS) for patients in early and advanced phase was 53 ± 7 vs 24 ± 8% (P = 0.006) and 48 ± 7 vs 22 ± 8% (P = 0.01), respectively. By comparing MAC with RIC patient groups, the transplant-related mortality was equivalent (36 ± 6 vs 28 ± 9%) while the relapse risk was lower for the MAC patients (22 ± 6 vs 45 ± 11%), who showed higher OS (48 ± 7 vs 29 ± 10%) and DFS (43 ± 7 vs 26 ± 10%). However, all these differences did not reach a statistical significance. In multivariate analysis, diagnosis and recipient age were significant factors for OS and DFS. In conclusion, this analysis confirms, on a longer follow-up and higher number of patients, our previous encouraging results obtained by using MAC and RIC TBF regimen as conditioning for G-CSF primed, unmanipulated BM transplantation from related, haploidentical donor in patients with high-risk hematological malignancies, lacking an HLA-identical sibling or unrelated donor and in need to be urgently transplanted.

RESUMO

Outcomes after unmanipulated haploidentical stem cell transplantation (Haplo) and after unrelated cord blood transplantation (UCBT) are encouraging and have become alternative options to treat patients with high-risk acute leukemia without human leukocyte antigen (HLA) matched donor. We compared outcomes after UCBT and Haplo in adults with de novo acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Median follow-up was 24 months. Analysis was performed separately for patients with AML, n=918 (Haplo=360, UCBT=558) and ALL, n=528 (Haplo=158 and UCBT=370). UCBT was associated with delayed engraftment and higher graft failure in both AML and ALL recipients. In multivariate analysis, UCBT was associated with lower incidence of chronic graft-vs-host disease both in the AML group (hazard ratio (HR)=0.63, P=0.008) and in the ALL group (HR=0.58, P=0.01). Not statistically significant differences were observed between Haplo and UCBT for relapse incidence (HR=0.95, P=0.76 for AML and HR=0.82, P=0.31 for ALL), non-relapse mortality (HR=1.16, P=0.47 for AML and HR=1.23, P=0.23 for ALL) and leukemia-free survival (HR 0.78, P=0.78 for AML and HR=1.00, P=0.84 for ALL). There were no statistically differences on main outcomes after unmanipulated Haplo and UCBT, and both approaches are valid for acute leukemia patients lacking a HLA matched donor. Both strategies expand the donor pool for patients in need.

RESUMO

BACKGROUND: The purpose is to measure the worsening of the Quality of Life (QoL) in people with Multiple Sclerosis (MS) and the concomitant role of co-morbid Major Depressive Disorder (MDD) and Bipolar Disorder (BD), the latter not yet studied even though it was found strictly associated with MS. CASES: 201 consecutive-MS-patients. CONTROLS: 804 sex-and-age-matched subjects without MS, randomly selected from an epidemiological database study. Psychiatric diagnoses according to DSM-IV were determined by physicians using structured interview tools (ANTAS-SCID). Bipolar Spectrum Disorders were identified by Mood Disorders Questionnaire (MDQ). QoL was measured by SF-12. RESULTS: MS was the strongest determinant in worsening the QoL in the overall sample. Both MDD and BD type-II lifetime diagnoses were significantly associated with a poorer quality of life in the total sample as in cases of MS. In MS the impairment of the QoL attributable to BD type-II was even greater than that in MDD. LIMITATIONS: The MS diagnosis was made differently in cases and controls. Although this may have produced false negatives in controls, it would have reinforced the null hypothesis (no role of MS in worsening the QoL); therefore, it does not invalidate the study. CONCLUSIONS: MDD as well BD type-II are co-determinants in worsening QoL in MS. Clinicians should consider depressive symptoms as well as the hypomanic and mixed components in MS. Additional research is required to confirm our results and further clarify the manner in which BD and the mixed symptoms of BD type-II may affect awareness of both the underlying disease and psychiatric component and finally to what extent they impact treatment adherence with the available therapies for MS.

RESUMO

OBJECTIVES: To test the hypothesis that neonatal supplementation with lutein in the first hours of life reduces neonatal oxidative stress (OS) in the immediate postpartum period. METHODS: A randomized controlled, double-blinded clinical trial was conducted among 150 newborns divided into control group, not supplemented (n = 47), and test group, supplemented with lutein on the first day postpartum (n = 103). Blood Samples were collected at birth from cord and at 48 hrs postpartum while routine neonatal metabolic screenings were taking place. Total hydroperoxide (TH), advanced oxidation protein products (AOPP), and biological antioxidant potential (BAP) were measured by spectrophotometry and data were analyzed by Wilcoxon rank sum test and by multivariate logistic regression analysis. RESULTS: Before lutein supplementation, the mean blood concentrations of AOPP, TH, and BAP were 36.10 umol/L, 156.75 mmol/H2O2, and 2361.04 umol/L in the test group. After lutein supplementation, significantly higher BAP increment (0.17 ± 0.22 versus 0.06 versus ± 0.46) and lower TH increment (0.46 ± 0.54 versus 0.34 ± 0.52) were observed in the test group compared to controls. CONCLUSION: Neonatal supplementation with lutein in the first hours of life increases BAP and reduces TH in supplemented babies compared to those untreated. The generation of free radical-induced damage at birth is reduced by lutein. This trial is registered with ClinicalTrials.gov NCT02068807.

RESUMO

A 57-year-old Italian man was admitted to our Hospital for investigation of a progressively raising alfa-fetoprotein (AFP) on the background of chronic hepatitis B infection. At abdominal imaging,liver morphology was suspected for advanced fibrosis but without any focal lesion. Clinical and ultrasonographic examinations were negative for testicular masses. When the patient was screened for gastroesophageal varices, upper intestinal endoscopy did not show signs of portal hypertension, while it revealed a gastric lesion which was histologically characterized as hepatoid adenocarcinoma of the stomach (HAS), with strong immunohistochemical positivity for AFP. The patient underwent subtotal gastrectomy and AFP fell within the normal range. This is a very rare case in which AFP-producing gastric cancer (AFPPGC), in the form of HAS, presented in a patient with chronic liver disease. Physicians should be particularly aware of AFPPGC when following patients with liver disorders due to the common use of AFP in this setting.

RESUMO

The incidence of cytomegalovirus (CMV) reactivations in patients with multiple myeloma (MM) receiving autologous stem cell transplantation (ASCT) is relatively low. However, the recent increased use of novel agents, such as bortezomib and/or immunomodulators, before transplant, has led to an increasing incidence of Herpesviridae family virus infections. The aim of the study was to establish the incidence of post-engraftment symptomatic CMV reactivations in MM patients receiving ASCT, and to compare this incidence with that of patients treated with novel agents or with conventional chemotherapy before transplant. The study was a survey of 80 consecutive patients who underwent ASCT after treatment with novel agents (Group A). These patients were compared with a cohort of 89 patients treated with VAD regimen (vincristine, doxorubicin, and dexamethasone) before ASCT (Group B). Overall, 7 patients (4.1%) received an antiviral treatment for a symptomatic CMV reactivation and 1 died. The incidence of CMV reactivations was significantly higher in Group A than in Group B (7.5% vs. 1.1%; P = 0.048). When compared with Group B, the CMV reactivations observed in Group A were significantly more frequent in patients who received bortezomib, whether or not associated with immunomodulators (9.4% vs. 1.1%; P = 0.019), but not in those treated with immunomodulators only (3.7% vs. 1.1%; P = 0.396). These results suggest that MM patients treated with bortezomib-based regimens are at higher risk of developing a symptomatic CMV reactivation after ASCT.

RESUMO

HLA matching is a critical determinant of outcomes for patients who have undergone umbilical cord blood transplantation (UCBT). Data have been published on the importance of donor/recipient HLA mismatch direction on UCBT outcomes. HLA mismatch in the graft-versus-host (GVH) direction is defined as a donor homozygous at an HLA locus, while the recipient shares one HLA Ag with the donor. HLA mismatch in the host-versus-graft (HVG) direction is defined as a recipient homozygous with the donor sharing one HLA Ag. In our study we focused on confirming, using an independent population, whether transplantation outcomes would be different when HLA mismatch direction was considered. We analyzed 1565 patients who received a single-unit UCBT for malignant disease. Median age was 15 years and 72% of patients were transplanted for leukemia. In multivariate analysis, using the 5/6 HLA-matched population as reference, one or two HLA mismatches in the GVH or HVG direction were not associated with non-relapse related mortality and survival. On the basis of our results, there is no evidence to support a change in the current practice for cord blood unit selection.
