RESUMO

OBJECTIVE: Thiols are organic compounds containing sulfhydryl groups that exert antioxidant effects via dynamic thiol-disulfide homeostasis. The shift towards disulfide indicates the presence of an oxidative environment. Different modes of delivery can affect thiol-disulfide homeostasis. Accordingly, we planned this research to evaluate the effects of the mode of delivery on thiol-disulfide homeostasis in both maternal serum and fetal cord blood samples. PATIENTS AND METHODS: We conducted a prospective case-control study involving two groups: vaginal delivery (n=50) and elective cesarean section (CS) (n=45). The vaginal delivery group exclusively comprised uncomplicated term deliveries, while the CS group included pregnant individuals with scheduled cesarean deliveries due to the absence of spontaneous labor onset. Maternal serum and fetal cord blood samples were collected, and thiol-disulfide exchanges were analyzed using an automated method capable of measuring both aspects of the thiol-disulfide balance. RESULTS: The levels of native thiol (-SH) and total thiol in both maternal serum and fetal cord blood samples were significantly higher in the vaginal delivery group than those in the CS group. An important discovery of our study was that fetal cord disulfide (-SS) level, which may reflect oxidative stress, was higher in newborns born via vaginal delivery when examined alone. However, in both maternal and fetal cord blood, the combined ratios, SS/SH ratio (%), SS/Total thiol ratio (%), and SH/Total thiol ratio (%) were observed to be similar between the groups in both maternal and fetal cord blood. It was observed that as the mother's weight gained during pregnancy increased, SS/SH and SS/total thiol increased (positive correlation), while SH/total thiol decreased (negative correlation). CONCLUSIONS: Our results showed that the dynamic thiol-disulfide homeostasis was greatly influenced by the way of delivery and supported the idea that vaginally-delivered infants may have more oxidative stress.

RESUMO

As significant transition metal sulfides, nickel sulfides integrated with carbon were successfully synthesized in the presence of polyethylenimine and glutaraldehyde with a solvothermal route at 180 °C followed by carbonization. Glutaraldehyde prevented complete sulfur loss and allowed the formation of a mixed phase of nickel sulfide. The electrochemical performances of pure NiS2, NiS@C0, NiS2/NiS@C1, and NiS2/NiS@C2 electrodes were tested by a series of measurements. The specific capacitances obtained from GCD analysis were 698, 1160, 1484, and 908 F g-1 at 1 A g-1 for NiS2, NiS@C0, NiS2/NiS@C1, and NiS2/NiS@C2 electrodes, respectively. The results implied that the NiS2/NiS@C1 electrode possessed the highest specific capacitances and this study can be a good reference for the preparation of other hybrid metal sulfides as pseudocapacitive electrode materials.

RESUMO

Background: In patients with coronavirus disease-2019 (COVID-19), severe dyspnea is the most dramatic complication. Severe respiratory difficulties may include electrocardiographic frontal QRS axis rightward shift (Rws) and clockwise rotation (Cwr). Aim: This study investigated the predictability of advanced lung tomography findings with QRS axis shift and rotation. Patients and Methods: This was a retrospective analysis of 160 patients. Patients were divided into the following two groups: normal (n = 80) and low (n = 80) oxygen saturation. These groups were further divided into four groups according to the rightward and leftward axis shift (Lws) on the electrocardiographic follow-up findings. These groups were compared in terms of electrocardiographic rotation (Cwr, counterclockwise rotation, or normal transition), tomographic stage (CO-RADS5(advanced)/CO-RADS1-4), electrocardiographic intervals, and laboratory findings. Results: In patients with low oxygen saturation, the amount of QRS axis shift, Cwr, and tomographic stage were significantly higher in the Rws group than in the Lws group. There were no differences in the above parameters between the Rws and Lws groups in patients with normal oxygen saturation. Logistic regression analysis revealed that the presence of Cwr and Rws independently increased the risk of CO-RADS5 by 18.9 and 4.6 fold, respectively, in patients with low oxygen saturation. Conclusion: In COVID-19 patients who have dyspnea with low oxygen saturation, electrocardiographically clockwise rotation with a rightward axis shift demonstrated good sensitivity (80% [0.657-0.943]) and specificity (80% [0.552->1]) for predicting advanced lung tomographic findings.

RESUMO

Methotrexate (MTX) is widely used for treating cancers and inflammatory diseases; it is a potential anti-metabolite and folate antagonist. We investigated potential protective effects of benfotiamine on MTX damage. We used a rat model of MTX induced gastric injury to assess changes in gastric histopathology, oxidative stress and visfatin levels due to MTX treatment. Rats were divided into four groups: an untreated control group, an MTX group treated with a single dose of MTX, a benfotiamine group treated with benfotiamine daily for two weeks, and a benfotiamine + MTX group treated with a single dose of MTX followed by benfotiamine daily for two weeks. Total tissue antioxidant status (TAS), total oxidant status (TOS) and visfatin levels were measured at the end of the experiment. At the end of the experiment, we investigated both visfatin expression and the histopathology of gastric tissues. The mean visfatin level was lower in the MTX group than in the benfotiamine group. The mean tissue TOS levels were higher in MTX group than in the control, benfotiamine or benfotiamine + MTX groups. Significant gastric gland dilation, and erosion and loss of mucosa were found on the gastric surface in the MTX group compared to the control group. The dilation, erosion and mucosal loss were decreased significantly in the benfotiamine + MTX group compared to the MTX group. Compared to the control group, visfatin immunoreactivity was reduced significantly in the MTX group. Decreased visfatin levels appear to play a role in the mechanism of gastric damage. Benfotiamine may be useful for preventing MTX induced gastric injuries.

RESUMO

BACKGROUND: There is an increased risk of long-term dental and periodontal disease in autoimmune bullous diseases (AIBD). AIMS: In this cross-sectional study, we aimed to determine whether the oral health-related quality of life status (OHRQoL) was associated with disease severity and activity in patients with AIBD. SUBJECTS AND METHODS: 67 patients with AIBD were enrolled in this study. Autoimmune Bullous Skin Disorder Intensity Score (ABSIS) was used to evaluate the disease severity. The score was categorized as a significant course (≥17) and moderate course (<17). Oral health impact profile-14 (OHIP-14) questionnaire was filled to assess the OHRQoL. Self-reported oral health status and oral lesion related pain score were also evaluated in the study group. RESULTS: OHIP-14 score was significantly higher in active patients (42.28 ± 13.66) than inactive patients (29.08 ± 12.25) (P = 0.004) and it was correlated with the pain score (6.33 ± 2.78; r = 0.409, P = 0.013). Furthermore, OHIP-14 score was higher in patients with a significant disease course (45.18 ± 15.08) (P = 0.010) than in patients with a moderate course (36.09 ± 9.73). CONCLUSIONS: OHRQoL may be useful in the disease management and treatment. Since it can be affected by both presence of oral erosions and disease severity, a collaboration between dermatologists and dentists could be crucial to the disease management in AIBD.

RESUMO

A successful root canal treatment can only be achieved by gaining adequate access to all root canals, ensuring adequate mechanical preparation, and disinfection as well as placing a three-dimensional impermeable filling in these root canals. Practitioners must be very careful when detecting the root canals in mandibular first molar tooth, because it shows a wide variety of root canal variations and it is the first permanent tooth erupted in the mouth that frequently requires endodontic treatment. Our case report presents the endodontic retreatment of a left permanent mandibular first molar having two roots that consist of three distal canals and two mesial canals (Type XVIII root canal pattern). After all the root canals were identified with endodontic explorer adequate preparation and disinfection were provided, the root canals were filled with calcium hydroxide-based canal sealer and gutta-percha and the crown was restored with resin composite at the second appointment. In addition, a short review of literature for similar cases is presented in this paper.

RESUMO

OBJECTIVE: Endothelial dysfunction may play an important role in the evolution of coronary artery ectasia (CAE). Endocan and thrombomodulin (TM) are two biomarkers released from the endothelium that are associated with dysfunction. We aimed to evaluate the levels of these markers in patients with isolated CAE. PATIENTS AND METHODS: Thirty-two patients with isolated CAE and thirty-five sex- and age-matched control patients with normal coronary angiograms were enrolled. Serum endocan and TM concentrations were measured with an enzyme-linked immunosorbent assay kit. RESULTS: The basal characteristics of the two groups were similar. Both endocan (1.19 ± 0.18 vs. 1.07 ± 0.15 ng/ml; p = 0.006) and TM (687.28 ± 150.85 vs. 571.27 ± 171.23 pg/ml; p = 0.007) were significantly increased in the CAE  group compared to controls. However, no significant differences were detected in the concentration of these markers when we grouped the subjects according to the Markis classification. CONCLUSIONS: We found higher endocan and TM levels in isolated CAE patients. However, these markers were not associated with CAE severity as assessed using the Markis classification. The results suggest that these markers play an important role in the development of isolated CAE.

RESUMO

INTRODUCTION: Mushroom intoxication (MT) can lead to acute liver injury which may result in Mushroom intoxication-related liver failure (M-ALF) requiring liver transplantation (LT). In the present study, we want to share the experience of our institute regarding living-donor LT (LDLT) due to mushroom poisoning. AIM: The aim of this study is to identify the predictors of poor prognosis in patients with ALF secondary to mushroom intoxication requiring LDLT. MATERIALS AND METHODS: All patients with MT between 2008 and 2016 were evaluated. Demographics, symptoms, interval between symptoms and admission to our institute, laboratory data, model for end-stage liver disease (MELD)/pediatric end-stage liver disease (PELD) scores, clinical course, and outcomes of supportive therapy and LT were evaluated. There were two groups in the study: Group A = responsive to supportive therapy (n = 9) versus Group B = unresponsive to supportive therapy (n = 9). RESULTS: During the study, a total of 18 patients were admitted with M-ALF. Twelve (66.7%) of them were female, and the mean age was 39.9 ± 18.2 years. All of the nine patients in Group A fully recovered with supportive therapy. In Group B, one patient died during waiting period for LT and 8 patients received LDLT LDLT. Three of the eight patients who were transplanted died in the postoperative early period within postoperative 5 days. The patients in Group B had significantly higher MELD/PELD scores and encephalopathy rate than in Group A (P < 0.05). International normalized ratio (INR), bilirubin, ammonium levels, and platelet count were significantly different between groups (P < 0.05). The patients in Group B had significantly longer interval before admission to our institute (P < 0.05). CONCLUSION: The presence of encephalopathy, higher MELD/PELD, INR, bilirubin, ammonium levels, and lower platelet count was related to poor prognosis in MT. LDLT provides a good therapeutic option in patients with M-ALF. The time is a crucial factor in successful treatment of MT. Early admission to a tertiary referral center with expertise in LT results in a better prognosis and increased survival following M-ALF.

RESUMO

BACKGROUND: The outcome of medical treatment is worse in fulminant liver failure (FLF) developing on acute or chronic ground. Recently, liver transplantations with the use of living and cadaveric donors have been performed in these diseases and good results obtained. In this study, we aimed to present the factors affecting the recovery of cerebral functions after liver transplantation in hepatic encephalopathy (HE) developing in FLF, to identify irreversible patient groups and to prevent unnecessary liver transplantation. METHODS: In Inonu University's Liver Transplant Institute, 69 patients who made an emergency notice to the National Coordination Center for liver transplantation owing to FLF from January 2012 to December 2015 were included in the study. Patients were divided into 2 groups. Group 1 consisted of 52 patients who underwent liver transplantation and recovered normal brain function, and group 2 had 17 patients who underwent liver transplantation and did not recover normal brain function and had cerebral death. All patients were evaluated before surgery for clinical encephalopathy stage, light reflex, and convulsions. Groups were compared and assessed according to age (>40, 10-40 and <10 years), body mass index, etiologic factor, preoperative laboratory values, transplantation type, mortality, and encephalopathy level. Multivariate analysis was done for specific parameters. RESULTS: Prothrombin time (PT), international normalized ratio (INR), and total bilirubin values were significantly different between the groups. There was no significant difference between the groups regarding ammonia and lactate levels. There was a statistically significant difference between the groups regarding sodium and potassium levels from serum electrolytes. However, the averages of both groups were within normal limits. pH and total bilirubin levels were meaningful for multivariate analysis. CONCLUSIONS: HE reversibility, mortality, and morbidity are important in patients with HE who undergo liver transplantation. Therefore, West Haven clinical staging and serum INR, PT, and total bilirubin level may be helpful in predicting the reversibility of FLF patients with HE before liver transplantation. It was determined that West Haven encephalopathy grading is important in determining the reversibility of HE after transplantation in FLF; especially the probability of reversibility of stage 4 HE decreases significantly. High PT and INR levels, hyperbilirubinemia, and serum sodium and potassium concentrations were risk factors for the reversibility of HE in this study.

RESUMO

PURPOSE: To determine the impact of clinical variables and adjuvant therapy on survival in patients with Stage IVB endometrial cancer (EC) confined to abdomen. METHODS AND METHODS: A total of 65 patients were included. Curative chemotherapy was defined as using only chemotherapy (platin based) or sandwich therapy. Patients receiving only radiotherapy had standard pelvic radiotherapy and extended-field radiotherapy when necessary. RESULTS: The optimal cytoreduction was achieved in 89.3% of patients. With a median follow-up of 18 months, two-year progression free survival (PFS) and overall survival (OS) were calculated as 33.4% and 42.2%, respectively. Optimal cytoreduction provided more longer PFS and OS compared to suboptimal cytoreduction. In univariate analysis, curative chemotherapy instead of radiotherapy improved the two-year PFS and two-year OS. Type of adjuvant therapy, tumor grade, and peritoneal cytology were found as the independent prognostic factors for PFS. Peritoneal cytology, adnexal involvement, and adjuvant therapy were independent prognostic factor for OS. CONCLUSION: Curative chemotherapy significantly improved both two-year PFS and OS in patients with Stage IVB endometrial disease confined to abdomen over only radiotherapy.

RESUMO

The effects of menopausal status and age on the intra-operative and post-operative pathology results of patients operated on with a pre-operative diagnosis of complex hyperplasia with atypia (CHA) were assessed. A hundred and eleven patients diagnosed in our centre between January 1993 and March 2013 were included. Cancer was detected in the paraffin blocks (PBs) of 52 (46.8%) patients. Among these, 50 patients had stage-IA disease. In 31.1% of the pre-menopausal patients and 66% of the post-menopausal patients, PB revealed cancer (p < 0.0001). The results of frozen section (FS) and PB were concordant in 51% and 70% in the pre-menopausal and post-menopausal patients, respectively (p = 0.041). In the patients operated on with a pre-operative diagnosis of CHA, the probability of detecting cancer in PB increases with increasing age and menopause. The reliability of FS is limited in younger and pre-menopausal patients.

RESUMO

BACKGROUND: The number of suitable donors for organ transplantation is limited in many countries. This limitation can be overcome with the use of organs removed from marginal donors (expanded-criteria donors [ECDs]). We examined the long-term results of 187 patients who underwent marginal cadaveric liver transplantation in our institution. METHODS: The data of patients who underwent cadaveric liver transplantation from January 2007 to April 2014 were retrospectively reviewed. ECDs were evaluated by considering 19 internationally accepted criteria. The clinical data of recipients including age, clinical status, and Model for End-Stage Liver Disease (MELD) score were also assessed. RESULTS: A total of 287 patients underwent cadaveric liver transplantation. A graft from an ECD was used in 181 (63.06%) patients. The mean MELD score was 18.8. In all, 45 patients (24.86%) underwent transplantations for fulminant liver failure and 136 patients (75.14%) underwent transplantations for other chronic conditions. The majority of donors died of cerebrovascular disease and trauma. Only hypotension requiring inotropic drugs and obesity significantly affected survival. The 90-day and 12-month survival rates of the recipients who received a graft from an ECD were 51.93% and 46.2%, respectively. CONCLUSIONS: The use of ECD allografts immediately and significantly expands the existing donor pool. Because of persistent organ scarcity, pressure to use a greater proportion of the existing donor pool will continue to increase.

RESUMO

AIM: Donor safety is the major concern in living-donor liver transplantation. Studies in literature related to donor hepatectomy (DH) have generally considered intra-abdominal complications. The aim of this study is to specifically evaluate pulmonary complications (PCs) after DH. MATERIALS AND METHODS: We evaluated retrospectively 1150 living donors who underwent to DH between January 2007 and July 2014. Patients with PCs, such as pneumonia, pleural effusion, pneumothorax, and respiratory insufficiency, were considered. A complication was considered only when it was clinically apparent and/or requiring interventions. Any special diagnostic tool was used to expose the clinically silent pathologies. RESULTS: A total of 986 right hepatectomies (RH) and 164 left hepatectomies (LH) (left lobectomy or left lateral segmentectomy) were performed in the study interval. There were 18 (1.6%) donors with PCs (15 males and 3 females). Mean age was 33.8 ± 9.3 years (18-51). Mean hospital stay was 23.8 ± 13.5 days (5-62). Presented PCs were pleural effusion (n = 5, 0.4%), pneumonia (n = 4, 0.3%), combinations (n = 2, 0.2%), pneumothorax (n = 2, 0.2%), and acute respiratory insufficiency (n = 5, 0.4%). Sixteen cases (1.7%) were seen after RH, whereas 2 cases (1.2%) were seen after LH (P = 1.000). CONCLUSION: The most common PCs after living donor hepatectomy were pleural effusion and acute respiratory insufficiency. There was no significant difference between RH and LH. It is possible to overcome those PCs with careful monitoring and timely and appropriate treatment.

RESUMO

INTRODUCTION: A shortage of deceased donors has compelled the use of extended-criteria donor organs in liver transplantation. The purpose of this study was to evaluate the impact of using deceased donors older than 80 years. MATERIALS AND METHODS: We retrospectively evaluated 13 patients who received a liver graft from cadaveric donors older than 80 years between December 2007 and March 2014. We analyzed the donor and their recipient characteristics together with morbidity and mortality of recipients. RESULTS: All 13 donors were older than 80 years (median age, 82.7; range, 80-93). There were 9 male and 4 female recipients with an average age of 50.7 (range, 2-65) years. All of the recipients did not have a living donor for liver transplantation. Recipients' mean model for end-stage liver disease (MELD) score was 14.2 (range, 7-20). Graft with macroscopic steatosis was not accepted. Medium follow-up was 19.5 months. The most frequent cause for liver transplantation (LT) was hepatitis B virus (HBV) cirrhosis (8/13 patients). We had 1 case of primary nonfunction, and 4 patients died in 2 weeks after surgery. Of these patients, 2 of them received a split transplant from an 80-year-old cadaver liver. Overall the survival rate after 1 year was 61.5%. CONCLUSIONS: Deceased elderly donor usage in LT could expand the donor pool. Liver grafts from donors older than 80 years can be used in necessity or emergency situations. However, care should be taken to avoid early mortality and primary nonfunction. Procedures extending cold ischemia time such as split liver transplantation may increase the risk of primary nonfunction.

RESUMO

INTRODUCTION: Liver transplantation may result in graft failure, requiring time and supportive treatment for regeneration of the graft. The aim of this study was to compare the laboratory parameter changes after single-session molecular adsorbent recirculating system (MARS) and plasmapheresis procedures among living donor liver transplantation patients experiencing graft failure. PATIENTS AND METHOD: We analyzed retrospectively the results in 45 liver transplantation patients treated with plasmapheresis and/or MARS between June 2011 and July 2012: (plasmapheresis, n = 17; MARS, n = 15; MARS + plasmapheresis, n = 13). When cadaveric donor cases (n = 11) were excluded, the remaining 34 included patients, underwent. MARS (n = 18) or plasmapheresis (n = 16) at the first session. FINDINGS: Both groups were similar in age, sex, and body mass index features. The MARS group displayed significantly higher levels of international normalized ratio, blood urea nitrogen, and Model for End-stage Liver Disease score. The plasmapheresis cohort, displayed significantly higher levels of initial direct bilirubin and gamma glutamyl transferase (P < .05). The plasmapheresis group showed a significant decrease in GGT after treatment (P < .05). RESULTS: An initial MARS session provided significantly greater decrease in renal function associated with graft failure after living donor liver transplantation.

Graft-versus-host disease (GVHD) after orthotopic liver transplantation (OLT) is a rare but significant complication, occurring in 1%-2% of cases with a mortality rate of 85%- 90%. It occurs when donor passenger lymphocytes mount an alloreactive response against the host's histocompatibility antigens. It presents as fever, rash, and diarrhea with or without pancytopenia. Between March 2002 and September 2011, among 656 OLT patients 1 (0.15%) had acute GVHD. A biopsy at the 7th posttransplantation month revealed chronic GVHD. Consequently, in the cases that had fever, rash, and/or desquamation of the any part of body after liver transplantation, GVHD must be considered and skin biopsies must be planned for the diagnosis.

RESUMO

In this study, we investigated gene delivery properties of Jeffamine-cored polyamidoamine (PAMAM) dendrimers (JCPDs). The effects of dendrimer concentration, generation, and core size on the gene delivery have been analyzed. The experimental results showed that the JCPD effectively delivered plasmid DNA inside the HeLa cells, and the transfection efficiency improved considerably as the number of generation increased. The cytotoxicity of JCPD in different concentration was tested for HeLa cell line. JCPD was complexed with a lacZ gene carrying plasmid and tested for transfection efficiency using quantitative ß-galactosidase expression assay. Additionally, confocal microscopy results revealed that JCPD effectively delivered green fluorescent protein-expressing plasmid into HeLa cells and produced fluorescent signal with satisfactory efficiency. The highest transfection efficiency was obtained from JCPDs G4 and G5, which mixed with expression plasmid vectors at a 10/1 weight ratio. These results indicated that under optimized conditions, JCPD can be considered as an efficient transfection reagent and can be effectively used for gene delivery applications.

RESUMO

OBJECTIVE: We report an extremely rare case of the oropharyngeal form of tularaemia, causing a parapharyngeal abscess. CASE REPORT: A 48-year-old woman presented with fever, sore throat, breathing difficulty and a right-sided neck swelling. This mass had previously been treated with penicillin without response, and had already been surgically drained once in another hospital. On physical examination, the tonsils were exudative and hypertrophic and the pharynx was hyperaemic. A fluctuant, 4 × 4 cm mass was seen on endoscopic examination, originating from the left parapharyngeal area and protruding towards the pyriform sinus, and partly obstructing the airway. Microagglutination test antibody titres for Francisella tularensis were positive (1/1280). The patient healed completely after definitive drainage of the abscess and antimicrobial therapy for 14 days (streptomycin, 2 × 1 g intramuscularly). CONCLUSION: Tularaemia should be considered in the differential diagnosis of patients presenting with tonsillopharyngitis, cervical lymphadenitis and parapharyngeal abscess who do not respond to treatment with penicillin, even if they do not live in an endemic region.

RESUMO

OBJECTIVES: This study investigated salivary lipid peroxidation (LPO) as an oxidative stress marker and salivary total sialic acid (TSA) as an inflammatory response during gestation and postpartum. DESIGN AND METHODS: Salivary LPO and TSA levels, using the Ledwozyw and Warren methods respectively, were obtained in healthy pregnant women followed up during gestation and 6-8 weeks postpartum, and in healthy non-pregnant controls. All were with good oral health. RESULTS: LPO was significantly higher than controls during all trimesters and postpartum and in the second trimester than in the third trimester and postpartum. TSA in the second trimester was significantly higher than in any other group. First trimester levels were significantly higher than postpartum . Oral health indices remained within normal levels for the duration. CONCLUSION: The salivary LPO profile followed plasma gestation and postpartum profiles in the literature but the salivary TSA differed in that after the 2nd trimester, rather than persisting, it decreased.

RESUMO

The aim of this study was to evaluate the efficacy and toxicity of EMA/CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine) regimen for the treatment of high-risk gestational trophoblastic neoplasia (GTN). Thirty-three patients with high-risk GTN, scored according to World Health Organization, received 159 EMA/CO treatment cycles between 1994 and 2004. Twenty-three patients were treated primarily with EMA/CO, and 10 patients were treated secondarily after failure of single agent or MAC (methotrexate, actinomycin D, cyclophosphamide, or clorambucile) III chemotherapy. Adjuvant surgery and radiotherapy were used in selected patients. Survival, response, and toxicity were analyzed retrospectively. The overall survival rate was 90.9% (30/33). Survival rates were 91.3% (21/23) for primary treatment and 90% (9/10) for secondary treatment. Six (18.2%) of 33 patients had drug resistance. Four of them underwent surgery for adjuvant therapy. Three of these patients with drug resistance died. Survival and complete response to EMA/CO were influenced by liver metastasis, antecedent pregnancy, and histopathologic diagnosis of choriocarcinoma. Survival rate was also affected by blood group. The treatment was well tolerated. The most severe toxicity was grade 3-4 leukopenia that occurred in 24.3% (8/33) of patients and 6.9% (11/159) of treatment cycles. Febrile neutropenia occurred in one patient (3%). EMA/CO regimen is highly effective for treatment of high-risk GTN. Its toxicity is well tolerated.
