ABSTRACT

Background: Medical 3D imaging is a promising emerging technology that allows recreating the details of human anatomy. The use of this innovative technology has resulted in improved surgical efficiency and better clinical outcomes. However, its incorporation in gynaecologic surgery has not been widely adopted. Objectives: To demonstrate the use of Hyper Accuracy 3D reconstruction in a patient with infertility who underwent multiple myomectomy. Materials and Methods: A stepwise approach describing the incorporation of Hyper Accuracy 3D imaging technology into the preoperative surgical planning and intraoperative guidance of a patient with multiple myomas undergoing multiple myomectomy. Main Outcome Measures: Preoperative evaluation of a patient with multiple myoma and infertility who presented to our department seeking surgical management. Hyper Accuracy 3D image was obtained, and a 3D digital image reconstruction of the uterus delineating the exact number, volume, and location of the fibroids was created. The 3D digital image was available during the surgical procedure which helped to plan the surgical steps allowing a systematic surgical approach resulting in an effective surgery with minimal blood loss. Results: The benefits of intraoperative guidance using Hyper Accuracy 3D in a patient with multiple myomas and infertility are demonstrated. Conclusions: The adoption of this promising imaging technology into gynaecologic surgery is feasible and should be further investigated. Additional studies evaluating the clinical impact of using Hyper Accuracy 3D imaging in the preoperative planning of patients with gynaecologic surgical pathology are needed.

ABSTRACT

The ATP-dependent molecular chaperone Hsp70 is over-expressed in cancer cells where it plays pivotal roles in stabilization of onco-proteins, promoting cell proliferation and protecting cells from apoptosis and necrosis. Moreover, a relationship between the ability of cancer cells to migrate and the abundance of membrane-associated Hsp70 was shown. However, although Hsp70 is a promising target for cancer therapy, there is a still unsatisfied requirement of inhibitors possibly blocking its cancer-associated activities. Moving from the evidence that the plant diterpene oridonin efficiently targets Hsp70 1A in cancer cells, we set up a small kaurane diterpenoids collection and subjected it to a Surface Plasmon Resonance-screening, to identify new putative inhibitors of this chaperone. The results obtained suggested epoxysiderol as an effective Hsp70 1A interactor; therefore, using a combination of bioanalytical, biochemical and bioinformatics approaches, this compound was shown to bind the nucleotide-binding-domain of the chaperone, thus affecting its ATPase activity. The interaction between epoxysiderol and Hsp70 1A was also demonstrated to actually occur inside cancer cells, significantly reduced the translocation of the chaperone to the cell membrane, thus suggesting a possible role of epoxysiderol as an anti-metastasis agent.

ABSTRACT

Adenosarcoma is an extremely rare malignancy of the female genital tract composed of stromal sarcoma with a benign epithelial component. Current treatment recommendations include total hysterectomy with bilateral salpingo-oophorectomy, precluding future fertility. Although most frequently diagnosed in postmenopausal women, it is occasionally present in younger women of reproductive age with desire for future fertility. In 2015, we reported the case of a 23-year-old patient diagnosed with uterine adenosarcoma, who having strong desire of future fertility, opted for fertility sparing surgery. At a follow-up five years later, we can now report her case of spontaneous pregnancy and livebirth. A review of the literature concerning fertility outcomes in patients with uterine adenosarcoma undergoing fertility sparing therapeutic options is presented.

ABSTRACT

Trabectedin is a marine-derivate antitumor drug with a relevant cytotoxic activity and good safety profile. It has been investigated for the treatment of solid diseases, including ovarian cancer (OC), breast cancer, and soft-tissue sarcoma. In 2009, results from the pivotal trial OVA-301 led the European Medicines Agency (EMA) to the approval of trabectedin in combination with PEGylated liposomal doxorubicin for the treatment of platinum-sensitive recurrent OC; further studies revealed an additional benefit also in the subgroup of patients with partially platinum-sensitive disease and in those with a BRCA-mutated status. Additionally, trabectedin demonstrated to prolong the time interval to the subsequent chemotherapy line. Recently, the improved understanding of the antitumor action exerted by trabectedin paved the way to new investigational trials exploring its combination with targeted therapies.

ABSTRACT

Postmenopausal bleeding (PMB) is a relevant aspect for health-care providers in clinical practice: the first objective is to rule out potential gynecological cancer. The purpose of this narrative review is to evaluate the role of office hysteroscopy in the management of PMB. Office hysteroscopy is a minimally invasive procedure allowing direct visualization of uterine pathology without the need for general anesthesia and the use of an operating room, generating cost savings and greater compliance among patients. Here, we focus on major intrauterine diseases (polyps, submucosal myomas, endometrial hyperplasia, and cancer) as causes of PMB. Office hysteroscopy appears to be safe and feasible, and could allow accurate diagnosis of intrauterine pathologies, especially that with a focal growth pattern, otherwise misdiagnosed with blinded procedures. However, studies focusing exclusively on postmenopausal women are still few, so further research, especially randomized controlled trials, is needed.

ABSTRACT

BACKGROUND: The therapeutic value of lymphadenectomy in early stage endometrial cancer (EC) is still debated. Sentinel-lymph-node identified with indocyanine green (ICG) can replace lymphadenectomy in the staging of endometrial cancer minimizing the potential morbidity of a complete lymphadenectomy. The aim of this study was to analyze our initial experience using indocyanine green for sentinel-lymph-node mapping in a minimally robotic-assisted laparoscopic approach with Da Vinci XI near-infrared (NIR) fluorescence imaging system. METHODS: A total of 23 patients who underwent robot-assisted laparoscopic surgery with the Da Vinci Xi Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) with NIR imaging and ICG fluorescence detection for early stage EC were retrospectively analyzed. RESULTS: Sentinel-lymph-node mapping was achieved in 18 patients for a detection rate of 78.26%, bilateral pelvic detection was possible in 14 patients (60.9%) and no sentinel-lymph-node mapping was noted in 4 patients (17.4%). We compared 11 patients (Group 1) at intermediate and high- risk of recurrence who underwent sentinel-lymph- node mapping and pelvic lymphadenectomy and 12 patients (Group 2) at low risk of recurrence who underwent only sentinel-lymph-node mapping. A statistically significant difference was found for the average operation time and for the hospital stays. CONCLUSIONS: The high detection rate, absence of intraoperative or postoperative complications, the short time required for mapping and removal of the sentinel-lymph-nodes and the short duration of the hospital stay, support performing sentinel-lymph-node in all women with early endometrial cancer.

ABSTRACT

BACKGROUND: Several randomised controlled trials (RCTs) have investigated the usefulness of pituitary block with gonadotrophin-releasing hormone (GnRH) antagonists during intrauterine insemination (IUI) cycles, with conflicting results. OBJECTIVE: The aim of the present systematic review and meta-analysis of RCTs was to evaluate the effectiveness of GnRH antagonist administration as an intervention to improve the success of IUI cycles. SEARCH STRATEGY: Electronic databases (MEDLINE, Scopus, EMBASE, Sciencedirect) and clinical registers were searched from their inception until October 2017. SELECTION CRITERIA: Randomised controlled trials of infertile women undergoing one or more IUI stimulated cycles with GnRH antagonists compared with a control group. DATA COLLECTION AND ANALYSIS: The primary outcomes were ongoing pregnancy/live birth rate (OPR/LBR) and clinical pregnancy rate (CPR). Pooled results were expressed as odds ratio (OR) or mean differences with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. The body of evidence was rated using GRADE methodology. Publication bias was assessed with funnel plot, Begg's and Egger's tests. MAIN RESULTS: Fifteen RCTs were included (3253 IUI cycles, 2345 participants). No differences in OPR/LBR (OR 1.14, 95% CI 0.82-1.57, P = 0.44) and CPR (OR 1.28, 95% CI 0.97-1.69, P = 0.08) were found. Sensitivity and subgroup analyses did not provide statistical changes in pooled results. The body of evidence was rated as low (GRADE 2/4). No publication bias was detected. CONCLUSION: Pituitary block with GnRH antagonists does not improve OPR/LBR and CPR in women undergoing IUI cycles. TWEETABLE ABSTRACT: Pituitary block with GnRH antagonists does not improve the success of IUI cycles.

ABSTRACT

OBJECTIVE: Cesarean scar pregnancy (CSP) is a rare condition that occurs when the pregnancy implants in a cesarean scar. An early diagnosis and a proper management are fundamental to prevent maternal complications. We review and discuss the different treatment employed in our unit to reduce morbidity, preserve fertility, and predict possible complications. METHODS: The reported treatment has been expectant management, operative hysteroscopy approach, and intramuscular injection of 50 mg methotrexate (MTX), followed by cervical dilation and manual vacuum aspiration (D&S) with a Karman cannula under ultrasound guidance, uterine artery embolization (UAE), and manual vacuum aspiration under ultrasound guidance and uterine artery embolization before surgical laparotomic resection. RESULTS: Complications were more frequent in women with a history of three or more cesarean section deliveries and with a myometrial thickness thinner than 2 mm. MTX and D&S treatment appear to be most effective and safe at the early age of pregnancy, while UAE and D&S are related to the highest risk of complication in any age of pregnancy. CONCLUSION: An appropriate preoperative diagnostic evaluation, the identification of cases at higher risk, and those eligible for a conservative treatment are fundamental to reduce complications.

ABSTRACT

OBJECTIVE: There is a growing body of evidence that suggests that the surgical technique for uterine closure following Cesarean delivery influences the healing of the Cesarean scar, but there is still no consensus on the optimal technique. The aim of this systematic review and meta-analysis was to compare the effect of single- vs double-layer uterine closure on the risk of uterine scar defect. METHODS: MEDLINE, Scopus, ClinicalTrials.gov, PROSPERO, EMBASE and the Cochrane Central Register of Controlled Trials were searched from inception of each database until May 2016. All randomized controlled trials (RCTs) evaluating the effect of single- vs double-layer uterine closure following low transverse Cesarean section on the risk of uterine scar defect were included. The primary outcome was the incidence of uterine scar defects detected on ultrasound. Secondary outcomes were residual myometrial thickness evaluated by ultrasound and the incidence of uterine dehiscence and/or rupture in subsequent pregnancy. Summary measures were reported as relative risk (RR) or mean difference (MD), with 95% CIs. Quality of the evidence was assessed using the GRADE approach. RESULTS: Nine RCTs (3969 participants) were included in the meta-analysis. The overall risk of bias of the included trials was low. Statistical heterogeneity within the studies was low, with no inconsistency in the primary and secondary outcomes. Women who received single-layer uterine closure had a similar incidence of uterine scar defects as did women who received double-layer closure (25% vs 43%; RR, 0.77 (95% CI, 0.36-1.64); five trials; 350 participants; low quality of evidence). Compared with double-layer uterine closure, women who received single-layer closure had a significantly thinner residual myometrium on ultrasound (MD, -2.19 mm (95% CI, -2.80 to -1.57 mm); four trials; 374 participants; low quality of evidence). No difference was found in the incidence of uterine dehiscence (0.4% vs 0.2%; RR, 1.34 (95% CI, 0.24-4.82); three trials; 3421 participants; low quality of evidence) or uterine rupture (0.1% vs 0.1%; RR, 0.52 (95% CI, 0.05-5.53); one trial; 3234 participants; low quality of evidence) in a subsequent pregnancy. CONCLUSIONS: Single- and double-layer closure of the uterine incision following Cesarean delivery are associated with a similar incidence of Cesarean scar defects, as well as uterine dehiscence and rupture in a subsequent pregnancy. However, the quality level of summary estimates, as assessed by GRADE, was low, indicating that the true effect may be, or is even likely to be, substantially different from the estimate of the effect.

ABSTRACT

The aim of this study was to evaluate whether supplementation of bovine culture medium with the natural antioxidant L-ergothioneine (LE), improves in vitro blastocyst development and quality, assessed as resistance to cryopreservation, total cells number, cellular differentiation, and apoptosis index. Abattoir-derived oocytes were matured and fertilized in vitro according to standard procedure. Twenty hours after IVF, presumptive zygotes were cultured in synthetic oviduct fluid with 0, 0.05 mM, 0.1 mM, 0.5 mM, and 1 mM of LE (experiment 1) at 39 °C under humidified air with 5% CO2, 7% O2, and 88% N2. On the basis of the results of this dose-response trial, the range of concentrations to test was reduced in experiment 2, in which presumptive zygotes were cultured with 0, 0.05 mM, and 0.1 mM of LE. On Day 7, embryo yields were assessed, and the blastocysts (BL) were vitrified by Cryotop method in 16.5% ethylene glycol, 16.5% DMSO and 0.5 M sucrose. Finally, BL produced on Day 8 in the absence (control) and presence of 0.1 mM LE were used for transferase-mediated dUTP nick end labeling and differential staining to evaluate, respectively the apoptotic rate and the allocation of cells into inner cell mass (ICM) and trophectoderm lineages (experiment 3). Despite similar blastocyst yields, supplementation of culture medium with 0.1 mM LE improved the cryotolerance of in vitro-produced (IVP) embryos compared to the control group, as indicated by higher (P < 0.05) hatching rates recorded after 48-hour post-warming culture (48.5%, 50.0%, and 63.8%, respectively with 0, 0.05, and 0.1 mM LE). Interestingly, when embryos were cultured in the presence of 0.1 mM LE, the percentage of BL with the most physiological ICM:total cells ratio (20%-40%) increased (85.1 vs. 66.0%, P < 0.05), confirming a beneficial effect on embryo quality. Furthermore, 0.1 mM LE decreased (P < 0.01) both the average number (4.3 ± 0.2 vs. 9.1 ± 0.3) and the proportion (3.6 ± 0.3 vs. 8.1 ± 0.5) of apoptotic cells in BL compared to the control. In conclusion, the enrichment of bovine culture medium with 0.1 mM LE improves embryo quality, as indicated by the improved cryotolerance, the lower apoptotic rate, and the higher percentage of BL with the most physiological ICM:total cells ratio.

ABSTRACT

OBJECTIVES: To assess and compare the ovarian reserve in patients with different-sized endometriomas undergoing cystectomy or ablative surgery in order to determine the best surgical approach to safeguard healthy ovarian tissue. STUDY DESIGN: Prospective randomized study on 48 patients with unilateral single ovarian endometriomas. Patients were allocated into two groups based on endometrioma size: <5cm (n=26, Group A, small endometriomas) and ≥5cm (n=22, Group B, large endometriomas). Each group was randomized to coagulation or excision treatment (1:1 ratio) before the procedure. Anti-Müllerian hormone (AMH) levels were evaluated before surgery and 3 months after surgery. RESULTS: Both ablation and excision resulted in a significant reduction in AMH level regardless of endometrioma size. A significant interaction effect was observed between endometrioma size and type of surgical technique (analysis of covariance p for interaction=0.039): in Group A, no significant difference was found between the two surgical techniques (-17.6±4.7% vs -18.2±10.6%), whereas in Group B, the excision group showed a significantly greater percentage decrease in AMH level compared with the ablation group (-24.1±9.3% vs -14.8±6.7%, p=0.011). CONCLUSIONS: Both ablative and excision treatment of endometriomas have a negative effect on ovarian function. Endometrioma size is associated with the magnitude of ovarian reserve damage following excision treatment, but in the case of ablative treatment, the decrease in AMH serum level is independent of the size of the cyst. In surgical treatment of large endometriomas, the decrease in AMH level is more consistent and much more severe following cystectomy than ablation.

ABSTRACT

The aims of this study were to assess the efficacy of alphacypermethrin (ACYP) on pediculosis due to Haematopinus tuberculatus and to evaluate the influence of the treatment on productive and reproductive performance in buffaloes (Bubalus bubalis) reared in an intensive system. The trial was performed on 56 pluriparous buffaloes at 86.8 ± 8.1 d in milk. The animals underwent individual louse count and were divided into 2 homogenous groups according to louse count, age, number of lactations, days in milk, live BW, BCS, pregnancy status, and milk yield. Group A (n = 28) was treated by a pour-on formulation of ACYP, and Group S (n = 28) was treated by pour-on saline solution. Individual louse counts were performed weekly on 10 buffaloes in each group. Feed intake was recorded daily and the total mixed ration, individual ingredients, and orts were analyzed to calculate DM ingestion. Individual milk yield was recorded daily and milk samples were analyzed at the beginning of the trial, after 4 wk, and at the end of the trial to assess milk composition. Individual BCS was also evaluated simultaneously. Finally, the animals underwent synchronization of ovulation starting 4 wk after treatment and the pregnancy rate and the calving-conception interval were evaluated. Data were analyzed by the Mann-Whitney test and ANOVA for repeated measures. The infestation was constant in Group S, whereas no lice were present in Group A throughout the study. Daily DMI was similar in the 2 groups (16.7 ± 0.4 vs. 16.3 ± 0.3 kg/d in Group A vs. Group S, respectively), although buffaloes in Group A showed higher (P < 0.05) BCS score at the end of the trial (7.39 ± 0.1 vs. 7.14 ± 0.1 in Group A vs. Group S, respectively). The average milk yield/buffalo was higher (P < 0.05) in Group A compared to Group S (10.58 ± 0.1 vs. 10.39 ± 0.1 kg in Group A vs. Group S, respectively) and this was mainly due to the higher milk production recorded in buffaloes at less than 75 d in milk (11.81 ± 0.1 vs. 11.45 ± 0.1 kg in Group A vs. Group S, respectively). Despite of a similar fertility rate (90.5 vs. 80.9% in Group A vs. Group S, respectively), a lower (P < 0.05) calving-conception interval was recorded in Group A compared to Group S (118 ± 16 vs. 177 ± 16 d in Group A vs. Group S, respectively). In addition to the pour-on treatment against pediculosis, productive and reproductive performance were also improved. This represents a significant improvement in dairy buffalo herd management.

ABSTRACT

The aim of the study was to evaluate whether resveratrol supplementation of bovine culture medium improves in vitro blastocyst development, embryo cryotolerance and cell numbers. Abattoir-derived oocytes were matured and fertilized in vitro according to standard procedure. Twenty hours after IVF, zygotes were cultured in SOF medium, supplemented with 0 (control, n=439), 0.25µM (n=422), 0.5µM (n=447) and 1µM resveratrol (n=416). On Day 7 (IVF=Day 0) blastocysts were vitrified by cryotop in 16.5% ethylene glycol, 16.5% dimethyl sulfoxide and 0.5M sucrose. Development rate, i.e. the percentage of embryos resuming development to reach a more advanced stage, and hatching rate were evaluated after 24 and 48h culture. Blastocysts cultured with (0.5µM) and without resveratrol underwent differential staining to count inner cell mass (ICM) and trophectoderm (TE) cells. Resveratrol during culture did not increase blastocyst yields (57.1, 57.7, 59.2 and 46.6%, respectively in 0, 0.25, 0.5 and 1µM resveratrol). However, 0.5µM resveratrol improved embryo cryotolerance compared to the control, as indicated by higher development rates (67.3% vs 50.3%, respectively; P<0.01) and hatching rates (58.9% vs 30.9%, respectively; P<0.01) recorded after 48h post-warming culture. Blastocysts produced in the control and in 0.5µM resveratrol groups had similar numbers of ICM (34.1 and 36.4, respectively), TE (88.1 and 85.3, respectively) and total (122.2 and 121.7, respectively) cells. In conclusion, low levels of resveratrol during in vitro culture improve the quality of IVP bovine embryos, as indicated by their increased resistance to cryopreservation.

ABSTRACT

OBJECTIVES: Lymphoceles are among the most common post-operative complications of pelvic lymphadenectomy, with a reported incidence of 1% to 29% in gynecology oncology. Several studies evaluated the effectiveness of biological glues on reducing lymphoceles, but no data on gynecological patients are available. We evaluated the effectiveness of cyanoacrylic glues (n-butyl cyanoacrylate) (Glubran 2 - GEM s.r.l., Italy) in preventing lymphocele on 30 patients who underwent pelvic lymphadenectomy for endometrial or cervical cancer. METHODS: Single-blind prospective randomized study. Patients were divided into 2 groups: pelvic lymphadenectomy plus n-butyl cyanoacrylate (treatment group: 44 patients) and pelvic lymphadenectomy without n-butyl cyanoacrylate (control group: 44 patients). Primary endpoint was incidence of pelvic lymphocele in the two groups 30 days after surgery, and evaluated with pelvic ultrasound and RMI examination. Secondary endpoints evaluated drainage volume of lymphorrhea 36, 48, 72 and 96 h after surgery. RESULTS: 15% in the treatment group and 36.6% in the control group had lymphocele 1month after the procedure (p<0.03; RR 0.4 [95% CI 0.152-0.999]). Concerning the secondary outcome in group A the amount of lymphorrhea presented a constant significant decrease during evaluation; on the contrary, in group B, after an initial decrease at 48 h, the amount of lymphorrhea remained unchanged; at all considered times the amount of lymphorrhea resulted significantly greater in controls. CONCLUSION: Intraoperative application of n-butyl cyanoacrylate seems to reduce lymph production after pelvic lymphadenectomy, providing a useful additional treatment option for reducing drainage volume and preventing lymphocele development after pelvic lymphadenectomy.

ABSTRACT

This paper describes an experience with the Alphascope, a fibreoptic hysteroscopy system (Gynecare, Ethicon Women's Health and Urology). This prospective observational study was carried out at a tertiary hospital in Naples, Italy. The study population comprised patients undergoing outpatient hysteroscopy with the semi-rigid Versascope Hysteroscopy System using the Alphascope. 7-Fr gauge mechanical instruments and 5-Fr bipolar electrodes (Versapoint, Gynecare, Ethicon Inc., Somerville, NJ) were used for the operative procedures. Outpatient hysteroscopy was successful in 97% of cases. These were diagnostic in 41%, while operative hysteroscopy was performed in 59% of cases. The endoscopic view was subjectively defined by the operator as good/excellent in 95% of procedures. A total of 98% of patients expressed moderate/high degree of satisfaction and only 2% were dissatisfied. The system is successful in the outpatient setting in 95% of attempts.

ABSTRACT

GOALS: To evaluate differences and changes in quality of life (QoL), lifestyle behavior and employment experience of young in comparison to midlife adults in response to early stage gynecologic cancer diagnoses. METHODS: 263 patients, divided into two age groups (Group A: ≤ 45 and Group B: >45 years), were interviewed on their QoL, lifestyle behavior (dietary habits, tobacco and alcohol use, physical activity) and employment experience (employment status and working time) at diagnosis and within 4 years from the treatment. The QoL was evaluated by European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) and its specific modules for each cancer type (in particular endometrium, cervix, ovarian and breast). RESULTS: Global health status was significantly different between the two groups. In the younger age group a more relevant cancer interference on family life and social activities and a greater impact on perception of health status have been observed. Young women were more affected by fatigue, constipation, gastrointestinal symptoms, lymphedema, poor body image and impaired sexuality. Cancer diagnosis had a major negative impact on employment of younger patients. Conversely, younger patients had overall better health behavior. They reported a higher daily intake of fruits and vegetables, along with lower alcohol consumption, furthermore they were a little more physically active than midlife adults. CONCLUSIONS: To enhance quality of life and to promote healthy lifestyle behavior of female cancer patients, particularly in younger age, it is essential to assure multidisciplinary approaches with specific medical intervention and psychosocial supports. Indeed, midlife adults seem to have a more rapid adaptive tendency to return towards levels of well-being, following cancer diagnosis and treatment, than younger patients.

ABSTRACT

BACKGROUND: Primary endometrial squamous cell carcinoma (PSECC) is a rare neoplasm. Squamous epithelium derived from endometrioid cancer or from cervical squamous cell carcinoma. The prevalence is about 0.1%. The genesis, histogenesis and biological behavior are unknown. CASE PRESENTATION: A 48-year old woman in postmenopause, referring pelvic pain and vaginal bleeding. Transvaginal ultrasound showed a bulky uterus with the endometrium containing an hyperecogenic area. Endometrial biopsy found an epidermoid carcinoma. MRI showed a 4 x 2 x 1.2 cm mass occupying the uterine cavity. The patient underwent radical treatment. Pathological examination showed features of PSECC. The mutation of p53 tumor suppressor protein was disclosed in 15% of neoplastic cells. PCR revealed the absence of HPV DNA. CONCLUSIONS: The findings of our case move us to underline that the pathogenesis of this tumor is still unclear. Moreover, preoperative diagnosis and staging of PESCC is extremely difficult. Most patients do not show characteristic symptoms and predisposing factors, making it almost impossible to diagnose the precise localization of tumor origin.

ABSTRACT

6-ethyl-chedeoxycholic acid (6E-CDCA) is a farnesoid X receptor (FXR) ligand endowed with agonistic activity under development for treatment of cholestatic liver diseases including primary biliary cirrhosis (PBC) and liver-related metabolic disorders including non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). FXR is a bile sensor that acts in coordination with other nuclear receptors to regulate essential steps of bile acid uptake, metabolism and excretion. 6E-CDCA has been investigated in preclinical models of cholestasis, liver fibrosis and diet-induced atherosclerosis. In a phase II clinical trial in patients with PBC, 6E-CDCA met the primary endpoint of a reduction in alkaline phosphatase levels but safety data indicated that the drug exacerbated pruritus, one of the main symptoms of PBC, suggesting that 6E-CDCA or FXR are mediators of pruritus in humans. Treatment of patients with diabetes and liver steatosis resulted in amelioration of insulin sensitivity despite a reduction a slight reduction in HDL and increased levels of LDL were observed. These side effects on bile acids and lipid metabolism were all predicted by pre-clinical studies, suggesting that potent FXR ligands hold promise but potential side effects might limit their development.
