RESUMO

The aim of the study was to investigate safety and if extracorporeal photopheresis (ECP) may change health criteria (HC) and quality of life (QoL). MATERIAL AND METHOD: 560 patients (33 % women) were treated with ECP for a total of 13,871 procedures during a 17-years period. Mean age was 48 years (±18, range 3-81 years). Self-estimation of QoL was graded: 0 (suicidal) up to 10 (best ever) and HC: 0 (Bed ridden, ICU condition) up to 10 (athletic). Adverse events were analyzed. ANOVA and paired comparisons were performed. RESULTS: Patients were treated due to graft versus host disease (GVHD, n = 317), skin lymphoma (n = 70), solid organ transplants (n = 47), skin diseases (n = 20) and other diseases (n = 106). Adverse events (AEs) were registered in 5.4 % of the first treatments and in 1.2 % of the subsequent procedures. Severe AEs were present in 0.04 % of all procedures. No patient died due to the procedure. Tingling and stitching were the most common AE. For those with GVHD an improvement was noticed within approximately 10 procedures of ECP in the severity stage, QoL (from a mean of 6.1 to 6.8, p < 0.002) and the HC (6.1 -> 6.4, p < 0.014) and improved further with added procedures. CONCLUSION: Photopheresis is an established therapy with few side effects. The present study of soft variables indicate that GVHD shows benefits upon ECP within approximately 10 procedures in regard to the severity of mainly skin GVHD, and lower baseline levels of HC and QoL.

RESUMO

OBJECTIVE: The World Apheresis Association (WAA) register contains data from more than 89 000 apheresis procedures in more than 12,000 patients. The aim of this study was to evaluate functional health and quality of life (QoL) in patients during apheresis treatment. MATERIAL AND METHODS: Estimates of health condition (HC) were made in 40,445 and of QoL in 22112 apheresis procedures. This study focused on a 10-step graded evaluation of HC (scale from: 'bedridden, unable to eat' to a level of 'athletic competition') and self-assessment of QoL (scale from: worst ever '0' to best ever '10'). Data were compared in relation to various apheresis procedures and if the patient underwent the first or subsequent apheresis procedure. RESULTS: Of the patients treated with plasma exchange (PEX) with centrifugation technique (n = 15787) 10% were 'bedridden, unable to come out of bed' while for patients treated with plasma filtration technique (n = 1018) the percentage was 27%. During the first procedure these figures were 16% and 30%, respectively. Self-estimates of QoL were graded 'zero' or '1' in 1.6% of patients during the first apheresis procedure; At the first contact patients undergoing PEX graded like this in 4.3%. CONCLUSION: Many of the patients undergoing apheresis treatment have poor HC and QoL at the start of therapy. Of all therapeutic apheresis procedures patients undergoing PEX had the lowest score of QoL.

RESUMO

BACKGROUND: Aging decreases bone marrow cellularity and alters the frequencies of stem cells. Aged hematopoietic stem cells can differ from their younger counterparts in functional capacity. STUDY DESIGN AND METHODS: We aimed to evaluate the relation between the age and the ability of colony forming capacity of peripheral blood-derived hematopoietic cell products collected for autologous stem cell transplantation (AHSCT). RESULTS: Elderly patients could be mobilized with lower total collected CD34+ cells. Colony forming capacity did not differ between young and old patients. CONCLUSION: This results can be translated into clinic as higher numbers of AHSCT candidates over age 60.

RESUMO

BACKGROUND: The viability of the hematopoietic stem cells infused to the patient is important for transplant outcome. STUDY DESIGN AND METHODS: We evaluated 31 peripheral blood stem cell product collected from 15 patients. We aimed to check the viabilities of the cells from patients with different age and diagnosis, in different stages of the cryopreservation procedure. RESULTS: We showed a markedly decreased viability rate after centrifugation and addition of DMSO. Percentages of viabilities were similar between young and old patients in each step. Type of hematological malignancy did not make a significant influence on the viability. CONCLUSION: High speed centrifugation has a negative impact on the viability.

RESUMO

INTRODUCTION: The impact of ABO mismatch on outcomes following allo-HSCT remains controversial. In this study, our aim is to define the effect of ABO mismatch on post-transplant outcomes, engraftment kinetics and complications in a large cohort. PATIENTS AND METHODS: We retrospectively identified 1000 patients who underwent allo-HSCT from either bone marrow or peripheral blood stem cells at our center between 1988 and 2016. P<0.05 was considered statistically significant. RESULTS: Five hundred and ninety (59%) patient-donor pairs were ABO matched, 164 (16.4%) were ABO major mismatched (MM), 191 (19.1%) were ABO minor MM, and 55 (5.5%) were ABO bi-directionally MM. ABO matched pairs were more common in transplants from related donors (P<0.001) and using bone marrow as a stem cell source (P<0.001). In minor ABO MM transplantations, mild delayed hemolytic reaction occurred more frequently compared to major and bidirectional ABO MM transplantations (47% vs 35% and 18%, P<0.001). Neutrophil engraftment was slightly delayed in ABO MM patient-donor pairs when compared ABO matched donor pairs according to median engraftment time in all group (167/410, 41% vs 204/590, 35%, P=0.046). Pure red cell aplasia was diagnosed in 6 patients (1%). Higher risk of death was shown in ABO MM transplants compared to ABO matched transplants in overall survival (OS) analysis (HR:1.201, 95% CI:1.004-1.437, P=0.045). The non-relapse mortality (P=0.546) and cumulative incidences of acute graft versus host disease (aGVHD) and chronic (c) GVHD were comparable between ABO MM and ABO matched patient-donor pairs (for aGVHD, P=0.235; for cGVHD, P=0.137). CONCLUSION: ABO MM transplants were associated with decreased OS and slightly delayed neutrophil engraftment. NRM and the risk of GVHD were not related to ABO incompatibility.

RESUMO

The renin-angiotensin system (RAS) is involved in cell growth, proliferation and differentiation in bone marrow in an autocrine-paracrine manner, and it modulates normal and neoplastic haematopoietic cell proliferation. This study aimed to assess expressions of the RAS components, renin, angiotensinogen and angiotensin-converting enzyme (ACE), during imatinib mesylate treatment of patients with chronic myeloid leukaemia (CML). Expressions of RAS components were studied in patients with CML at the time of diagnosis (n = 83) and at 3, 6 and 12 months after diagnosis (n = 35) by quantitative real-time polymerase chain reaction. De novo CML patients had increased ACE, angiotensinogen and renin mRNA levels and these expression levels decreased following administration of imatinib. The RAS activities were significantly different among Sokal risk groups of CML, highlighting the altered biological activity of RAS in neoplastic disorders. The results of this study confirm that haematopoietic RAS affects neoplastic cell production, which may be altered via administration of tyrosine kinase inhibitors such as imatinib mesylate.

RESUMO

OBJECTIVES: Chronic graft versus host disease (GVHD) is one of the major obstacles to achieve success in allogeneic hematopoietic stem cell transplantation (allo-HSCT). Extracorporeal photochemotherapy (ECP) has been demonstrated to be an effective modality for the treatment of GVHD in previous studies but they vary in terms of initiation and duration. Our aim is to demonstrate the characteristics of our patients who received ECP for chronic GVHD to clarify the best treatment scheme. MATERIAL AND METHODS: In this study, we retrospectively evaluated 34 patients with steroid refractory chronic GVHD (n=34) who were treated with ECP between 2001 and 2015. The initiation of ECP was determined according to patient status and the physician's preference. RESULTS: ECP was initiated early (≤3months) as the preferred second-line treatment after failure of methylprednisolone treatment in 12 patients (35%), 22 steroid refractory patients (65%) received ECP later. In all cohorts, 10 (29%) and 14 (41%) of 34 patients achieved complete response (CR) and partial response (PR), respectively, with an overall response rate (ORR) of 70. Early initiation of ECP after chronic GVHD diagnosis (≤3months vs more than 3months) was associated with increased rates of response (92% vs 59%, P=0.046) in which the severity of diseases were similar. Patients with skin involvement in early treatment group had statistically better response. Mild side effects were detected in only 6 patients (16%). CONCLUSION: ECP is a safe treatment modality and particularly effective when initiated soon after steroid failure in chronic GVHD.

RESUMO

Considerable information is available regarding the experimental and clinical applications of bone marrow derived stem cells (BMDSC) for regenerative medicine. Optimized stem cell delivery systems might help to maintain better stem cell viability. We have investigated whether needle diameters and flow rates through the needles cause any difference in terms of BMDSC viability.

RESUMO

OBJECTIVES: Extracorporeal photo-chemotherapy (ECP, photopheresis) is an approved treatment modality for mycosis fungoides (MF). Our aim is to present our ECP data for MF. METHODS: We retrospectively evaluated 50 MF patients who received ECP for clinical activity, toxicity, and response and outcome rates, and we compared these with combination therapies. RESULTS: The overall response rate (ORR) was 42% (21/50), while the median time to response was 11months (range, 3-48months). Ten of the responders (48%) had 3 or more treatment lines prior to ECP. Eight patients (16%) had adverse events related to ECP. The overall survival (OS) of 50 patients was 72months (range, 3-211). There was no statistically significant difference in the OS in early-stage vs late-stage patients (77 vs 69months, P=0.077). The stage 3 and 4 patients received an average of 31 cycles compared to 55 cycles in stage 1 and 2 patients (P=0.006). The increased extent of ECP was not correlated with the response. Combined treatment with ECP significantly improved the OS (84months vs 62months, P=0.005). DISCUSSION: A low frequency of side effects and improved OS observed in combination therapy makes ECP a favorable option for treating MF.

RESUMO

BACKGROUND: Increased serum levels of homocysteine (Hcy) have been reported in patients with Behçet's disease (BD) with an established risk factor for vascular involvement. Recently, the authors demonstrated that elevated Hcy levels are associated with ocular involvement in such patients. On the other hand, elevated levels of Hcy can result from genetic errors. Indeed, a mutation in the 5,10-methylenetetrahydrofolate reductase (MTHFR C677T) gene influences Hcy metabolism and, therefore, MTHFR C677T polymorphism provokes hyperhomocysteinaemia. AIM: To investigate the possible genetic factor for the elevation of plasma Hcy level in patients with BD by examining gene interaction with the MTHFR C677T polymorphism, a crucial factor of the Hcy metabolism. In addition, the authors aimed to evaluate if there is an association between the C677T polymorphism and the presence of ocular involvement in such patients. METHOD: A total of 59 patients with BD (25 men, 34 women) with a mean age of 34.9 years and 42 age and sex matched healthy control subjects (19 men, 23 women; mean age 32.2) were included in this investigation. MTHFR gene polymorphism was investigated by the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of a genomic DNA fragment at nucleotide 677 in all subjects in both groups. The genetic equilibrium is assumed for the gene frequencies of the MTHFR polymorphism in both samples. RESULTS: The genotype of the MTHFR gene differed between the Behçet's patients and control subjects (TT: 11.9 v 2.4%; CT: 55.9 v 61.9%; CC: 32.2 v 35.7 %). TT homozygous genotype was more frequently in BD patients than the controls, though the difference was not significant (p = 0.063). In BD patients with ocular involvement, however, the frequencies of MTHFR TT homogenetic type (27.8%) were significantly and statistically higher than those in BD patients without ocular involvement (4.9%, p = 0.022, odds ratio = 7.5), or the controls (2.4%, p = 0.003, odds ratio = 20.0). TT homozygous genotype was associated with an increased risk for ocular involvement. CONCLUSION: Elevated serum levels of Hcy seem to be a result of C677T polymorphism of the MTHFR gene, with increased TT individuals over CC and CT genotype BD patients. Although no association was shown between the MTHFR reductase C677T polymorphism and the increased risk of oral aphtahe or genital ulcers, a mutation in this gene was associated with an increased risk of ocular involvement, suggesting genetic instability with a potential initiation of Hcy lowering therapy in this patient group.

RESUMO

The clinical correlations of serum tumor necrosis factor alpha (TNF-alpha), a cytokine which can be released from leukemic blasts, has not been extensively studied. We have analyzed serum TNF-alpha in 20 ANLL, one CML-myeloblastic crisis, and 14 ALL adult patients by using a commercial ELISA kit. Sterile serum samples were taken on day 0, day 7, during remission and relapse with a mean follow-up period of 4.2 (1-19) months. After a median of 7 days following chemotherapy, serum TNF-alpha decreased both in responding ANLL (p = 0.004) and ALL (p > 0.05) but remained high in refractory leukemias. Values on day 7 were significantly different between responding and refractory patients in both ANLL (p = 0.0027) and ALL (p = 0.0099). At relapse, serum TNF-alpha increased starting at a median of 3 months preceding clinical symptoms in ANLL (p = 0.002). However, the relapse of ALL coincided with a slight increase which was not significant (p > 0.05). Together these findings indicate that serum TNF-alpha can be used as an early predictor of clinical response and relapse in ANLL.

RESUMO

PURPOSE: To evaluate the effectiveness of intravitreal triamcinolone acetonide as primary treatment of macular edema in branch retinal vein occlusion. METHODS: Fifteen eyes of 15 patients with macular edema due to branch retinal vein occlusion (Group 1) who received 8 mg/0.2 ml of intravitreal triamcinolone injection as primary treatment were retrospectively evaluated. The control group (Group 2) consisted of 19 eyes of 19 patients who had received laser treatment for macular edema. The main outcome measures included best-corrected visual acuity, intraocular pressure, and macular edema map values of Heidelberg Retinal Tomograph II. RESULTS: In Group 1, mean visual acuity improved significantly from a mean logMAR (logarithm of minimal angle of resolution) value of 0.98+/-0.19 at baseline to a maximum of 0.24+/-0.24 during a mean follow-up time of 6.3 months. In the control group, the mean baseline log-MAR visual acuity before laser treatment was 1.02+/-0.22, and it was 0.50+/-0.28 at 6-month examinations. Mean improvement in visual acuity at 1-, 3-, and 6-month examinations was significantly higher in Group 1 when compared with the control group (for each, p<0.001). The mean edema map value of Group 1 significantly decreased by 40% at 6-month examinations when compared with preinjection value (p<0.001). In Group 1, mean increase in intraocular pressure elevation was 19.8% at the 1-month, 26.9% at 3-month, and 5.7% at 6-month visits, but intraocular pressures were under control with topical antiglaucomatous medications. CONCLUSIONS: Intravitreal triamcinolone acetonide injection may be a new and promising approach as initial therapy for macular edema due to branch retinal vein occlusion.

RESUMO

Congenital alveolar synechiae is rarely seen as an isolated disease. It is generally observed together with various syndromes such as Van der Woude and cleft palate lateral alveolar synechiae syndrome, and is concomitant with other anomalies in the maxillofacial or other regions of the body. Prior to this case report , eight cases of isolated congenital alveolar synechiae have been reported. This paper reports a case of isolated congenital alveolar synechiae in a 10-month-old baby girl. The report concentrates on the clinical features of isolated congenital alveolar synechiae, the likely aetiological causes and the treatment.

RESUMO

OBJECTIVE: The resistance of blood to flow is called plasma viscosity. Increased blood viscosity has been described in patients with coronary and peripheral arterial disease. In this study, we evaluated the influence of clinical and laboratory findings on plasma viscosity in renal transplant recipients. METHODS: Eighty-one kidney transplant recipients (37.8 ± 11.3 years old, 50.38 ± 16.8 months post-transplantation period, 27 female) with normal graft functions were enrolled. The biochemical and clinical parameters in the 1st year after transplantation were retrospectively recorded, and graft function was evaluated by means of the yearly decline in eGFR. Plasma viscosity was measured and searched for the association with cross-sectionally analyzed cardiovascular parameters including body composition analyses, ambulatory blood pressure monitoring (ABPM) data, and pulse-wave velocity. RESULTS: Patients were divided into 2 groups according to the median value of serum viscosity. Patients with high viscosity had higher serum low-density lipoprotein (P = .042) and C-reactive protein (P = .046) levels than lower viscosity group. In ABPM, daytime (P = .047) and office systolic (P = .046) blood pressure levels and left ventricular mass index (LVMI; P = .012) were significantly higher in patients with hyperviscosity. Patients with high viscosity had higher hip circumference (P = .038) and fat mass (P = .048). Estimated glomerular filtration rate decline was significantly higher in high-viscosity patients than in patients with low viscosity levels (12.9% vs 17.2%; P = .001) at 2 years' follow-up. CONCLUSIONS: We suggest that the hyperviscous state of the renal transplant recipients may arise from the inflammatory state, hypertension, and increased fat mass and increased LVMI. Hyperviscosity is also closely related to renal allograft dysfunction.

RESUMO

Fourty-four patients who underwent allogeneic bone marrow transplantation (alloBMT) were studied for hepatitis B virus (HBV)-related complications. The mean follow-up period was 15.3 months. Positivity for HBV surface antigen (HBsAg) was observed in 10 patients (22.7%) throughout the study. Four of the 10 patients were HBsAg carriers before alloBMT, while the remaining six became HBsAg(+) after alloBMT. During the follow-up period (from 6 months to 45 months), an elevation in serum ALT activity was observed in the four carriers when immunosuppression was reduced or withdrawn. All of the four HBsAg carriers developed hepatitis, but none of them died of liver failure due to HBV. Only one death due to GVHD and diabetic ketoacidosis was observed in this group. Two of the four carriers received marrow from anti-HBs positive donors and one of them cleared HBsAg from his serum via adoptive immunity 8 months after transplantation. The remaining six patients acquired HBV after alloBMT, but we were unable to demonstrate the source of HBV. Five of them had a moderate increase in serum ALT activity while the other patient had a normal ALT. Two patients seroconverted to anti-HBs spontaneously. Two patients died during the follow-up, one due to intracranial hemorrhage and the other due to GVHD and accompanying pulmonary infection. The rest of the study group (34 patients) remained HBsAg(-) throughout the study. Two of them had an HBsAg(+) donor, but neither developed HBV infection in their follow-up period. The acquisition rate of HBV infection was relatively low in recipients who were positive for anti-HBs compared to those who were negative for anti-HBs (8 vs 19%). Anti-HBs positivity remained for a longer period in recipients who received marrow from anti-HBs positive donors compared to those recipients who had anti-HBs negative donors (median 12 vs 3 months). We think that HBV is a frequent cause of liver dysfunction in alloBMT patients where HBV infection is endemic. Whether the disease is in the form of reactivation of HBsAg-positive recipients, or is acquired from unknown sources in recipients who never had contact with the virus, the course of the disease is not fatal. Silent serologic changes can be demonstrated if viral serologic markers are sought serially. Among them, the disappearance of serum anti-HBs may be important as it increases the risk of HBV contamination in recipients.

RESUMO

The purpose of this study was to determine the maximum tolerated dose of carboplatin administered with 500 mg/m2 thiotepa and 100 mg/m2 melphalan followed by autologous peripheral blood stem cell (PBSC) infusion in patients with refractory malignancies. Twenty-eight patients with refractory malignancies received high-dose thiotepa (500 mg/m2, melphalan (100 mg/m2) and escalating doses of carboplatin 900-1500 mg/m2) followed by infusion of cryopreserved autologous PBSCs. The maximum tolerated doses were determined to be 500 mg/m2 thiotepa, 100 mg/m2 melphalan and 1350 mg/m2 carboplatin. Two consecutive patients receiving 1500 mg/m2 carboplatin experienced grade 3 mucositis and colitis. Ten patients were enrolled at the maximum tolerated dose and none had grade 3-4 regimen-related toxicity and mortality. All patients at this level experienced grade 1-2 mucositis, 90% grade 1-2 gastrointestinal toxicity, 30% grade 1-2 cardiac and renal toxicity, and 10% experienced grade 1 hepatic toxicity. The median time to achieve a granulocyte count of 0.5x10(9)/l was 9 days (range 7-12 days) and platelet count of 20x10(9)/l was 10 days (range 7-15 days). Of eight patients with stage IV refractory breast cancer, even were evaluable for response, one patient on day 75 will be evaluated soon. Five of seven (71.5%) evaluable patients achieved a complete remission (CR) and two had no response. Of seven patients with non-Hodgkin's lymphoma (n = 4) or Hodgkin's disease (n = 3), five achieved a CR (71.5%). Thiotepa, melphalan and carboplatin can be administered in high doses with tolerable mucositis as the major side-effect. This combination has significant activity in patients with breast cancer, and phase II studies in patients with breast cancer and other chemotherapy-sensitive malignancies are warranted.

RESUMO

Acquired ichthyosis (AI) has rarely been described following bone marrow transplantation (BMT). We report a 29-year-old male, who underwent allogeneic peripheral blood stem cell transplantation (alloPBSCT) for chronic myelogenous leukemia, and who developed AI associated with chronic graft-versus-host disease (cGVHD). Both of these disorders were treated successfully with cyclosporin A. We conclude that AI may be related to an autoimmune process on the basis of cGVHD, and dermathopathologic evaluation must be performed in patients with skin changes suggesting AI following allogeneic bone marrow transplantation.

RESUMO

Since transplantation cannot be performed immediately after the diagnosis of chronic myelogenous leukemia (CML), interferon treatment is usually required. This study aims to analyze the effects of interferon-alpha (IFN) treatment on allogeneic stem cell transplantation (SCT) outcome. A total of 106 patients aged 16-47 years and transplanted from HLA-identical sibling donors for CML in chronic phase (CP) were evaluated. In all, 48 had received IFN-alpha for a median duration of 5 months (1-18 months) until a median of 1 month prior to transplantation. Of the patients, 50 have received bone marrow transplant (BMT) whereas 56 have received peripheral blood stem cells (PBSCT) between 1991 and 1999 in three major transplant centers in Turkey. Patient characteristics in both groups were similar. More hematological responders were present in the IFN(+) patients (P=0.0001). No difference was found in engraftment kinetics. The incidences of acute or chronic graft-versus-host disease (GVHD), relapse and graft failure were similar in all patients regardless of stem cell source. Overall survival (OS) and disease-free survival (DFS) at 2 years were similar for both IFN(+) or (-) patients following SCT. With multivariate analysis, pretransplant IFN-alpha use, stem cell source, transplant year and CD34+ cell content were not found to be risk factors for OS. In conclusion, prior IFN exposure did not impair BMT or PBSCT outcome.

RESUMO

The purpose of this evaluation was to investigate the efficacy of high-dose chemotherapy with thiotepa, melphalan, and carboplatin (TMCb), and of autologous peripheral blood stem cell (PBSC) infusion in patients with aggressive non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD). A total of 42 patients, 23 with intermediate-grade NHL and 19 with HD, received thiotepa (500 mg/m2), melphalan (100 mg/m2), and carboplatin (1050-1350 mg/m2) followed by autologous PBSC infusion. Of 21 patients with more advanced disease, four had primary refractory disease, one was in complete remission (CR)-2, 11 were in first refractory relapse, and five were beyond first relapse. Of 21 patients with less advanced disease, two were in CR-1, four were in CR-2, and 15 were in first responding relapse. In all, 14 patients (33%) had received prior radiotherapy prohibiting a total-body irradiation (TBI)-based conditioning regimen. The projected 2-year probabilities of survival, event-free survival (EFS), and relapse for all patients were 0.65, 0.60, and 0.21 (0.85, 0.80, and 0.10 for patients with less advanced disease and 0.47, 0.42, and 0.33 for patients with more advanced disease). The probability of nonrelapse mortality in the first 100 days was 0.12. Grade 3-4 regimen-related toxicities (RRT) occurred in five of 42 (12%) patients and death due to grade-4 RRT occurred in only one (2.5%) patient. These preliminary data suggest that 0.42% EFS in this study for advanced disease patients is highly encouraging and high-dose TMCb followed by autologous PBSC transplantation is well tolerated as well as an effective regimen in patients with intermediate-grade NHL or HD, and may be comparable to some previously used regimens including TBI-based regimens.
