RESUMO

BACKGROUND: The goal is to assess the role of immature granulocytes (IG) in the diagnosis of acute pelvic-inflammatory-disease (PID) and to determine whether they are useful for discriminating mild/moderate and severe PID. METHODS: Patients admitted with the diagnosis of acute PID were retrospectively assessed. Diagnosis was based on CDC criteria. Patients were grouped as severe and mild/moderate PID based on need for hospitalization. Control group consisted of patients in whom PID was excluded by laparoscopy. Sample size was calculated with statistical methods. IGs were compared within the groups. Cutoff values were determined for prediction of diagnosis and severity of acute PID. RESULTS: There were 74 severe, 32 mild/moderate acute PID, and 41 control patients. Thirty patients had surgery following no response to antibiotic treatment or tubo-ovarian abscess. IGs were significantly higher in the severe group compared to mild/moderate and control groups. ROC analysis showed IG counts (≥ 0.035 µL) and percentages (≥ 0.35%) were significantly effective in predicting acute PID and were associated with severity when they were ≥ 0.055 µL and ≥ 0.42%, respectively. IG count ≥ 0.085 was found to have 58.6% sensitivity and 63.1% speci-ficity for prediction of surgical intervention need. CONCLUSIONS: IGs are components of simple CBC tests and are easily obtainable, cheap markers. They were found to be elevated in acute PID and correlated significantly with the severity of the disease. These markers may serve as adjunctive markers for the diagnosis of acute PID and may be useful in discrimination between mild/moderate and severe PID.

RESUMO

OBJECTIVES: Our aim was to compare patients with high-risk chronic lymphocytic leukemia referred to our transplant center who underwent allogeneic stem cell transplant with those who did not receive this treatment. Factors compared included demographics, clinical characteristics, and survival rates in the novel targeted therapy era. MATERIALS AND METHODS: All 33 patients with high-risk chronic lymphocytic leukemia who were referred to the hematopoietic stem cell transplant center were enrolled in this retrospective, single-center nonrandomized study. Outcomes of patients who received allogeneic stem cell transplant were compared with those of nontransplant patients. Chemoimmunotherapy and ibrutinib were given when indicated. Factors related to overall and progression-free survival were assessed. RESULTS: Thirteen patients underwent allotransplant, and transplant was not done in 20 patients for various reasons. Demographic and clinical features of the transplant and nontransplant groups were similar. The estimated cumulative overall survival was 72.6 ± 15 and 84.3 ± 13 months in the nontransplant and transplant groups, respectively. The 5-year overall and progression-free survival rates in the transplant and nontransplant groups were 57.3%/36.0% and 40%/20.6%, respectively. In the nontransplant group, overall survival of those who used ibrutinib was longer than overall survival in patients in the transplant group who used the same drug, but the difference was not statistically significant. Although not significant, overall survival in patients who did not use ibrutinib was longer in the transplant group than in the nontransplant group. Cox regression analyses showed that transplant, relapse, and Binet stage were independent predictors of overall survival. CONCLUSIONS: In patients who do not use ibrutinib, allogeneic stem cell transplant improved survival compared with nontransplant patients. Addition of ibrutinib provided comparable life expectancies, showing that allogeneic stem cell transplant and ibrutinib may have complementary roles. Transplant is still an independent predictor of overall survival.

RESUMO

OBJECTIVES: Our aim was to identify factors associated with overall survival and the efficacy of postrelapse treatment protocols and to determine whether pretransplant consolidation therapy and minimal residual disease status pose a survival benefit. MATERIALS AND METHODS: Patients with acute myeloid leukemia who underwent stem cell transplant between 2007 and 2018 were enrolled retrospectively. The effects of pretransplant cytogenetic and minimal residual disease status, pretransplant consolidation therapies, development of graft-versus-host disease, postrelapse treatment protocols, and type of con-ditioning regimens on overall survival were analyzed. RESULTS: In 76 study patients, the cumulative overall 1- and 5-year relapse probabilities were 67.8% and 58.7%, respectively. Overall survival rates at 3 and 5 years in patients with and without relapse were 23.5% and 0% and 95.9% and 91.1% (P < .001), respectively. Although mean postrelapse overall survival was better with intensive salvage plus donor lymphocyte infusion, no significant differences were shown versus other therapies (intensive salvage, nonintensive salvage, intensive salvage or nonintensive salvage plus donor lymphocyte infusion, or supportive therapy). Twenty-three patients (30.3%) died during the study period with a median survival of 9.6 months. Patients with favorable, intermediate, and unfavorable cytogenetic status showed overall survival of 46.6 ± 10.4, 54.6 ± 4.4, and 36.9 ± 5.9 months (P = .807). Patients with and without minimal residual disease and patients who received or did not receive consolidation therapy had similar overall survival. Relapse was an independent predictor of overall survival (increased mortality risk of 26.22). Patients who developed graft-versus-host disease showed decreased relapse. CONCLUSIONS: Relapse is the most important predictor of overall survival and is associated with poor prognosis. Pretransplant minimal residual status and cytogenetic status showed no effect on relapse rates and overall survival, and consolidation therapy did not improve outcomes.

RESUMO

BACKGROUND: Approximately half of patients with relapsed chemosensitive disease achieve robust responses with BEAM (BCNU, etoposide, cytarabine, and melphalan) and autologous stem cell rescue. The scarcity of comparative studies further limits alternative treatment protocols, such as the MITO/MEL (mitoxantrone, melphalan) protocol. PATIENTS AND METHODS: In this retrospective multicenter study, we compared the BEAM and MITO/MEL regimens used before autologous hematopoietic stem cell transplantation (ASCT) in terms of efficacy and side effects in patients with Hodgkin lymphoma. Data met international accreditation rules. Before ASCT, 108 patients received the MITO/MEL, and 34 patients received the BEAM. RESULTS: The median follow-up time was 36 months in the MITO/MEL group (range, 3-178) and 23 months in the BEAM group (range, 4-99). After ASCT, the 3-year expected overall survival and disease-free survival rates were 86.1% and 86.1% for the MITO/MEL group and 91.3% and 76.5% for the BEAM group, respectively. Although 50% of patients developed febrile neutropenia attacks in the MITO/MEL group, this rate was 91.1% in the BEAM group. The grade II and higher rates of hepatic, renal, gastrointestinal, and cardiac toxicities were similar in both groups. However, the rate of pulmonary toxicity was determined to be 1.9% in the MITO/MEL group and 29.4% in the BEAM group (P < .001). CONCLUSION: The MITO/MEL conditioning regimen seems to be as effective as the BEAM regimen but has better tolerability in terms of pulmonary toxicity and may be used as an alternative option if necessary, depending on the comorbidity status of the patient.

RESUMO

BACKGROUND: In countries where frontline drug approval is limited to first-generation proteasome inhibitors or immunomodulatory drugs, relapses have been both more frequent and less durable. We investigated real world data on the efficacy and safety of daratumumab monotherapy among patients with relapsed refractory multiple myeloma (RRMM) from Turkey using a prospective early access program. PATIENTS AND METHODS: A total of 42 patients with RRMM after a minimum of 3 previous lines of proteasome inhibitor/immunomodulatory drug-based treatments were included from 25 centers across Turkey. Daratumumab monotherapy was administered intravenously at a dose of 16 mg/kg weekly (cycles 1-2), on alternate weeks (cycles 3-6), and monthly thereafter. RESULTS: The median daratumumab monotherapy duration was 5.5 months (range, 0.2-28.7 months). The overall response rate was 45.2%, including 14 (33.3%) partial responses, 4 (9.5%) very good partial responses, and 1 (2.4%) complete response. The median duration of response was 4.9 months. The median progression-free survival (PFS) was 5.5 (95% confidence interval, 2.6-8.4 months) with 12- and 18-month PFS rates of 35.7% and 31.0%, respectively. The median overall survival was not reached; the 12- and 18-month overall survival rates were 64.3% and 59.5%, respectively. The depth of response had a significant effect on PFS (log-rank test, P = .026). Overall, of the 76 adverse events reported, 33 (43.4%) were grade ≥ 3; only 4 (9.52%) were grade 3 infusion-related reactions. No infusion-related reactions or adverse events led to treatment discontinuation. CONCLUSION: The present findings from our daratumumab early access program have confirmed the efficacy and safety profile of daratumumab monotherapy in heavily pretreated Turkish patients with RRMM.

RESUMO

BACKGROUND: Chronic myeloid leukemia (CML) is a disease resulting from BCR-ABL gene fusion. It is possible to monitor treatment by molecular testing for BCR-ABL. The lymphocyte-to-monocyte ratio (LMR) is a commonly used marker associated with prognosis in various neoplasms. This study was performed to evaluate the relevance of absolute lymphocyte count (ALC), absolute monocyte count (AMC), and LMR in predicting molecular response status in patients with chronic phase CML. METHODS: Samples submitted to our hematology laboratory for BCR-ABL testing between April 2012 and October 2018 were retrospectively reviewed. Concurrent hemogram testing together with the results of quantitative reverse transcriptase-polymerase chain reaction were noted. Data were grouped according to molecular response status and the ALC, AMC, and LMR were compared among patient groups. RESULTS: A total of 224 samples from 95 patients were included in the study. Analysis revealed differences between groups when newly diagnosed patients were compared with patients undergoing treatment, regardless of response status. However, analyzing the groups according to molecular response status failed to reveal differences in ALC, AMC, or LMR. CONCLUSIONS: ALC, AMC, and LMR are not potential biomarkers for predicting molecular response status in patients with chronic phase CML.

RESUMO

OBJECTIVE/BACKGROUND: Anti-T lymphocyte globulin Fresenius (rATG-F; ATG-Fresenius) and antithymocyte globulin (thymoglobulin), which are included in transplant protocols, are used to reduce the risk of chronic graft-versus-host disease (cGVHD) or suppress allograft rejection. Available clinical studies have been conducted in heterogenous patient populations and with different administration protocols including stem cell sources. Additionally, the pharmacokinetics of ATG is variable, and the clinically effective dose of rATG-F, in particular, is not exactly known. The aim of the study was to investigate the clinical outcomes of acute myeloid leukemia (AML) patients who underwent hemopoietic peripheral stem cell transplantation from full-matched sibling donors and given two different doses of r-ATG-F. METHODS: This was a single-center, retrospective chart review conducted between July 2005 and July 2016. Sixty-nine consecutive AML patients who underwent transplant with fludarabine- and busulfan-based conditioning were included in the study. Patients in Group 1 received 15 mg/kg body weight rATG-F to 2013 (n = 46), and Group 2 received 30 mg/kg of rATG-F dose begining in 2013 to reduce to cGVHD (n = 23). Cyclosporine and methotrexate were used to treat acute GVHD (aGVHD) prophylaxis. Outcome parameters were compared between the groups. RESULTS: Although the recommended dose r-ATG-F had led to a decrease in the cumulative incidence of cGVHD (27 [58.7%] vs. 8 [34.8%]; p = .03), it also increased the infection rate at 1 year (3 [6.5%] vs. 4 [17.4%]; p = .02). The two groups were similar in terms of engraftment time, aGVHD, relapse, nonrelapse mortality, and rATG-F-related toxicity. A Cox regression model revealed that aGVHD III-IV was associated with increased nonrelapse mortality at 1 year (hazard ratio = 18.2; 95% confidence interval, 1.667-199.255; p = <.02). No patients developed rATG-F-related severe adverse events (Common Terminology Criteria grade 4 or 5). CONCLUSION: Dose difference of rATG-F did not influence survival parameters; however, increasing the dose to 30 mg/kg seems to be effective for reducing cGVHD with an increase in infection rate requiring close monitoring of infections in AML patients who received myeloablative fludarabine/busulfan conditioning.

RESUMO

The Eastern Mediterranean is among the regions where sickle cell disease (SCD) is common. The morbidity and mortality of this disease can be postponed to adulthood through therapies implemented in childhood. The present study focuses on the organ damage-reducing effects of the Baskent Sickle Cell Medical Care Development Program (BASCARE), which was developed by a team who lives in this region and has approximately 25 years of experience. The deliverables of the program included the development of an electronic health recording system (PRANA) and electronic vaccination system; the use of low citrate infusion in routine prophylactic automatic erythrocyte exchange (ARCE) programs including pregnant women; the use of leukocyte-filtered and irradiated blood for transfusion; the use of magnetic resonance imaging methods (T2) for the management of transfusion-related hemosiderosis; and the implementation of an allogeneic hematopoietic stem cell transplantation protocol for adult patients. The sample was composed of 376 study subjects and 249 control subjects. The hospital's Data Management System and the central population operating system were used for data collection. BASCARE enabled better analysis and interpretation of complication and mortality data. Vaccination rates against influenza and pneumococcal disease improved (21.5% vs 50.8% and 21.5% vs 49.2%, respectively). Effective and safe ARCE with low citrate infusion were maintained in 352 subjects (1003 procedures). Maternal and fetal mortality was prevented in 35 consecutive pregnant patients with ARCE. Chelating therapy rates reduced from 6.7% to 5%. Successful outcomes could be obtained in all 13 adult patients who underwent allogeneic peripheral stem cell transplantation from a fully matched, related donor. No patients died by day 100 or after the first year. Cure could be achieved without graft loss, grades III to IV acute graft versus host disease, extensive chronic graft versus host disease, or other major complications. The BASCARE program significantly improved patient care and thereby prolonged the life span of SCD patients (42 ± 13 years vs 29 ±â€Š7 years, P < .001). We may recommend using such individualized programs in centers that provide health care for patients with SCD, in accordance with holistic approach due to the benign nature but malignant course of the disease.

RESUMO

BACKGROUND AND OBJECTIVE: Assessment of Hemoglobin S trait donors has gained importance together with the increased allogeneic peripheral stem cell transplant activity for sickle cell disease in the regions where the disease is prevalent. Outcomes of Granulocyte-Colony Stimulating Factor (G-CSF) administration are obscure for hemoglobin S trait donors. This study aims at investigating the incidence of hemoglobin S carrier status and outcomes of G-CSF administration among donors who live in Eastern Mediterranean region. MATERIAL AND METHOD: The cross-sectional, single-center cohort study was performed with 147 donors between January 2013 and March 2017. Prevalence of hemoglobin S trait was estimated and subjects with or without Hemogobin S trait were compared with regard to stem cell characteristics, early and late clinical outcomes after G-CSF administration. RESULTS: Eleven out of 147 donors (7.48%) were found as hemoglobin S trait. G-CSF administration was successfully completed and yielded good harvesting results in hemoglobin S trait donors. No statistically significant difference was found between groups with regard to early and late side effects, stem cell characteristics. Blood pressures and QTc values were within normal ranges in both groups. Groups were similar with regard to CD34 values. CONCLUSION: G-CSF seems safe in hemoglobin S trait donors. Their being eligible as donors would increase the chance of the patients for allogeneic stem cell transplantation in high prevalence regions. Further studies are required to reveal the safety profile of G-SCF in hemoglobin S carriers in different regions.

RESUMO

Terlipressin is a synthetic vasopressin analogue that is used in the treatment of bleeding esophageal varices and hepatorenal syndrome in patients with cirrhosis. Hepatorenal syndrome is a form of renal failure seen in patients with cirrhosis, with fatal outcomes. Ischemic adverse effects related to terlipressin are rarely observed. Herein, two cases who developed ischemic skin necrosis due to terlipressin usage are presented. Terlipressin therapy was started in two cirrhotic patients with presumptive hepatorenal syndrome. During the therapy, ecchymotic and necrotic changes were observed on the scrotal regions of both patients. Skin lesions were relieved after terlipressin therapy. Biopsy results were consistent with ischemia. Even if seen rarely, possible emergence of ischemic complications must be considered.

RESUMO

OBJECTIVE: To examine the effects of linezolid in prevention of adhesion formation in a rat uterine horn model. DESIGN: Prospective randomized study. SETTING: University Experimental Animal Research Laboratory Center. SAMPLE: Ninety female Wistar albino rats. METHODS: A dose response study was first conducted with 60 Wistar albino rats that were randomly assigned to six equal groups by administering vehicle (control), 5 mg/kg (Group 1), 15 mg/kg (Group 2), 50 mg/kg (Group 3), 100 mg/kg (Group 4), and 150 mg/kg (Group 5) linezolid starting three days before the adhesion inducing operation and continuing for 14 days postoperatively. Adhesion was scored clinically with a scoring system. The minimum effective dose was found to be 100 mg/kg/day. With this dose time response (starting three days before the operation and continuing for seven days), only preoperative and postoperative administration studies were conducted. MAIN OUTCOME MEASURES: Extent and severity of adhesions. RESULTS: Total adhesion scores in the control and Groups 1 and 2 were significantly higher when compared with Groups 4 and 5, but not with Group 3. There were no significant differences in the adhesion scores between Groups 3, 4, and 5. In time response arm a total of 10 days treatment was not as effective as 17 days treatment. In postoperative and preoperative arms of the study, it was found that administration of linezolid only postoperatively or preoperatively did not affect adhesion formation significantly when compared with the control group. CONCLUSION: Linezolid was found to reduce intraperitoneal adhesion formation.

RESUMO

BACKGROUND: The effect of rosiglitazone, an activator of peroxisome proliferator-activated receptor-gamma, on the growth of ectopic uterine tissue was assessed. METHODS: Endometriosis was surgically induced in 28 rats by transplanting an autologous fragment of endometrial tissue onto the inner surface of the abdominal wall. Four weeks later, rats were randomly grouped and a second laparatomy was performed. The length, width, height and volume of the explants were measured. Rosiglitazone at 0.2 mg/kg/day was orally administered to one group, while vehicle treatment was given to the control group. Four weeks later, rats were sacrificed and ectopic uterine tissues were re-evaluated morphologically and histologically. Scoring system was used to evaluate the preservation of epithelia. RESULTS: One rat in the study group and two rats in the control group died as a result of complications related to surgery. There was a significant difference in post-treatment length, width, height, and spherical volumes between control and rosiglitazone-treated groups. The epithelia were found to be preserved significantly better in the control group when compared with the rosiglitazone-treated group. CONCLUSION: Rosiglitazone was found to cause regression of experimental endometriosis in rats.

RESUMO

OBJECTIVE: To assess the effect of the peroxisome proliferator-activated receptor (PPAR)-gamma agonist rosiglitazone on the induction of endometriosis in a rat model. METHODS: Endometriosis was surgically induced in 28 rats by transplanting an autologous fragment of endometrial tissue onto the inner surface of the abdominal wall. Group I was assigned as control and no medication was administered. Starting 3 days before the operation and continuing for 4 weeks, 0.2 mg/kg/d rosiglitazone was administered to the study group orally. Four weeks later rats were killed and ectopic uterine tissues were evaluated morphologically and histologically. Scoring systems were used to evaluate preservation of epithelia. RESULTS: Four rats in the study group and one rat in the control group died of complications related to surgery. There was a significant difference in post-treatment spherical volumes (64.00 mm3 [interquartile range (IQR): 354.42] vs 41.60 mm3 [IQR: 37.87], P = .018) and explant weights (77.97 mg [IQR: 431.27] vs 47.24 mg [IQR: 43.01], P = .005) between control and rosiglitazone-treated groups. The epithelia were found to be preserved significantly better in the control group when compared with the roziglitazone-treated group (2.00 [IQR:2.00] vs 0.00 [IQR:2.25], P = .014). CONCLUSIONS: Rosiglitazone was found to affect the induction of endometriosis negatively in this experimental rat model and seemed to interfere with the growth and maintenance of the uterine explant.
