Abstract Background: Repeated implantation failure (RIF) is one of the difficulties that hinder the further improvement of clinical pregnancy rate by assisted reproductive technology. RIF has become an urgent clinical problem and hot research topic in the field of assisted reproduction, which is also a challenge for clinicians.Objective: The aim of this study was to evaluate the effects of intrauterine recombinant human granulocyte colony-stimulating factor(rhG-CSF) to improve implantation, clinical pregnancy, early abortion, multiple pregnancy and live birth rate(LBR) rate in women with RIF. Methods: A retrospective clinical analysis involving 142 women with RIF was conducted in the reproductive Medicine Center, the First Hospital of Lanzhou University between 1 January 2015 and 30 June 2018. They were divided into two groups: rhG-CSF group and control group, according to whether or not intrauterine rhG-CSF. In rhG-CSF group (n=47) granulocyte colony-stimulating factor (300 micrograms in 1 mL) was infused into the uterus within five minutes by embryo transfer cathete during the proliferative period of menstrual cycle before freeze-thaw embryo transfer(FET), while the control group was not given intrauterine perfusion. The implantation, clinical pregnancy, early abortion and multiple pregnancy were compared between the two groups. Results:The mean age for whole study group was 35.3±4.2 years old. There were no significant differences between demographic characteristics in two groups(p>0.05). The successful implantation (28.44% vs 12.44%, p=0.012), and clinical pregnancy (48.95% vs 27.35%, p=0.011) rates were significantly higher in the rhG-CSF group than in the control group. Binary logistic regression indicated that rhG-CSF treatment remained significantly associated with successful clinical pregnancy(OR=2.979, 95% CI=1.262-7.003).Conclusion: Intrauterine infusion of rhG-CSF can increase embryo implantation rate, clinical pregnancy rate in patients with RIF. In addition, the age and rhG-CSF are the independent risk factors affecting pregnancy outcomes.

Background: Nearly 25-50% of infertile women have endometriosis. There are reports of disorders in the expression of granulocyte colony-stimulating factor (G-CSF) receptors in women with endometriosis. Objective: To examine the effect of intrauterine administration of G-CSF in in vitro fertilization (IVF) cycles on the fertility rate of infertile women with moderate-to-severe endometriosis. Materials and Methods: This clinical trial was conducted on 66 infertile women with moderate-to-severe endometriosis, undergoing IVF and intracytoplasmic sperm injection (ICSI). The participants were allocated into two groups via simple randomization: the G-CSF (n = 27) and control (n = 39) groups. In the G-CSF intervention group, on the oocyte pick-up day, immediately after an ovarian puncture, 300 μg of G-CSF was injected through a transcervical catheter under abdominal ultrasound guide to visualize flushing into the uterine cavity. Women in the control group received no intervention. The two groups were evaluated for clinical pregnancy. Results: No significant difference was noted in the demographic characteristics of the two groups. The rate of clinical pregnancy was 28.2% in the control group and 25.9% in the G-CSF group, indicating no significant difference (p = 0.83). Conclusion: The results showed that the intrauterine injection of G-CSF had no effects on pregnancy in women with stage-3/4 endometriosis undergoing IVF.

Abstract Recent studies have revealed key roles for granulocyte colony-stimulating factor (GCSF) in embryo implantation process and maintenance of pregnancy, and some studies showed promising results by using local intrauterine infusion of GCSF in patients undergoing in vitro fertilization (IVF). This multicenter, randomized, controlled trial included 112 infertile women with repeated IVF failure to evaluate the efficacy of systemic single-dose subcutaneous GCSF administration on IVF success in these women. In this study, the Long Protocol of ovarian stimulation was used for all participants. Sealed, numbered envelopes assigned 56 patients to receive subcutaneous 300 µg GCSF before implantation and 56 in the control group. The implantation (number of gestational sacs on the total number of transferred embryos), chemical pregnancy (positive serum β-HCG), and clinical pregnancy (gestational sac and fetal heart) rates were compared between the two groups. This trial is registered at www.irct.ir (IRCT201503119568N11). The successful implantation (18% vs 7.2%, P=0.007), chemical pregnancy (44.6% vs 19.6%, P=0.005), and clinical pregnancy (37.5% vs 14.3%, P=0.005) rates were significantly higher in the intervention group than in the control group. After adjustment for participants’ age, endometrial thickness, good-quality oocyte counts, number of transferred embryos, and anti-Mullerian hormone levels, GCSF treatment remained significantly associated with successful implantation (OR=2.63, 95% CI=1.09–6.96), having chemical pregnancy (OR= 2.74, 95% CI=1.11–7.38) and clinical pregnancy (OR=2.94, 95% CI=1.23–8.33). In conclusion, administration of single-dose systemic subcutaneous GCSF before implantation significantly increases the IVF success, implantation, and pregnancy rates in infertile women with repeated IVF failure.

AbstractBackgroundThe aim of this study was to evaluate the therapeutic effects of coronary granulocyte colony-stimulating factor (G-CSF) on rats with chronic ischemic heart disease (CIHD).MethodsThirty healthy rats were randomly divided into control, subcutaneous and intracoronary G-CSF injection groups (n = 10) after the CIHD model was established. Left ventricular ejection fraction (LVEF), myocardial injury area, myocardial perfusion area and viable myocardium were observed by coronary angiography, dual-isotopic myocardial imaging and first-pass delayed myocardial perfusion magnetic resonance imaging (MRI) before modeling as well as 2 and 4 weeks after surgery.ResultsThe peak times of peripheral blood and subcutaneous G-CSF levels were 3 and 5 days after mobilization, respectively. The peripheral blood CD34+/CD133+ cell ratio of subcutaneous or intracoronary G-CSF injection group significantly exceeded that of the control group (P < 0.05). The distal stenosis degrees of target lesions in subcutaneous and intracoronary G-CSF injection groups were significantly lower than that of the control group (P < 0.05). Compared with the situation before mobilization, LVEF was significantly improved after 2 weeks in intracoronary and subcutaneous G-CSF injection groups (P < 0.01). Their infarcted myocardial areas were reduced, the left ventricular remodeling was relieved, the percentage of viable myocardium was increased, angiogenesis was promoted and cardiomyocyte apoptosis was inhibited.ConclusionIntracoronary G-CSF injection is safe and effective as subcutaneous injection, improving the cardiac function of CIHD rats.

Object Granulocyte colony-stimulating factor (G-CSF) has neuroprotective effects on the CNS. The authors have previously demonstrated that G-CSF also exerts neuroprotective effects in experimental spinal cord injury (SCI) by enhancing migration of bone marrow–derived cells into the damaged spinal cord, increasing glial differentiation of bone marrow–derived cells, enhancing antiapoptotic effects on both neurons and oligodendrocytes, and by reducing demyelination and expression of inflammatory cytokines. Because the degree of angiogenesis in the subacute phase after SCI correlates with regenerative responses, it is possible that G-CSF's neuroprotective effects after SCI are due to enhancement of angiogenesis. The aim of this study was to assess the effects of G-CSF on the vascular system after SCI. Methods A contusive SCI rat model was used and the animals were randomly allocated to either a G-CSF–treated group or a control group. Integrity of the blood–spinal cord barrier was evaluated by measuring the degree of edema in the cord and the volume of extravasation. For histological evaluation, cryosections were immunostained with anti–von Willebrand factor and the number of vessels was counted to assess revascularization. Real-time reverse transcriptase polymerase chain reaction was performed to assess expression of angiogenic cytokines, and recovery of motor function was assessed with function tests. Results In the G-CSF–treated rats, the total number of vessels with a diameter > 20 μm was significantly larger and expression of angiogenic cytokines was significantly higher than those in the control group. The G-CSF–treated group showed significantly greater recovery of hindlimb function than the control group. Conclusions These results suggest that G-CSF exerts neuroprotective effects via promotion of angiogenesis after SCI.

Objective: To investigate the clinical effect of granulocyte colony-stimulating factor combined with erythropoietin on chronic granulocytic leukemia with anemia and its effect on nutritional status. Methods: 60 patients of chronic granulocytic leukemia of our hospital with anemia induced by maintenance chemotherapy were randomly divided into two groups. Patients in the control group received routine treatment, while patients in the observation group received basal treatment with granulocyte colony-stimulating factor and erythropoietin. The nutritional status before and after treatment as well as the immune function and the incidence of blood transfusion and adverse events were compared between the two groups. Results: There was no significant difference in hemoglobin, hematocrit, nutritional status and immune function between the two groups before treatment (P>0.05). Those after treatment were significantly higher than that before treatment (P<0.05). After treatment, the percentage of CD4* cells in the control group was significantly higher than that before treatment (P<0.05), but the percentage of CD8* cells and CD47/CD8* cells did not change significantly (P>0.05). After treatment, the concentrations of IgA, IgM and IgG in the observation group were significantly higher than those before treatment (P<0.05), but only the concentrations of IgA and IgM in the control group were significantly higher than those in the observation group after treatment (P<0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group. Conclusion: Granulocyte colony-stimulating factor combined with erythropoietin can effectively correct anemia, improve nutritional status and improve immune function in patients with chronic myelogenous leukemia.

Abstract Study question To assess the role of subcutaneous granulocyte colony-stimulating factor (G-CSF) in thin endometrium cases. Summary answer G CSF has beneficial role to improve the endometrium thickness in thin endometrium. What is known already Endometrium is very important for embryo implantation and the endometrial thickness is the marker of receptivity of the endometrium. Study design, size, duration Study design - Retrospective analysis Size - 88 infertile females with thin endometrium (&lt; 7 mm) in the age group of 23 to 40 years Duration - one year. Participants/materials, setting, methods In the group 1 of 44 females, subcutaneous infusion of G CSF (300 mcg/ml) was added along with other supplements and if lining was not more than 7 mm in 72 hours, then second infusion was given. In the group 2 of 44 females, only estradiol valerate and sildenafil were given.The efficacy of G CSF was evaluated by assessing the endometrium thickness before embryo transfer, pregnancy rates and clinical pregnancy rates. Main results and the role of chance There was no difference between the two groups regarding demographic variables, egg reserve, sperm parameters, number of embryos transferred and embryo quality. . The pregnancy rate was 60% (24 out of 40 cases) in the group 1 that was significantly higher than in-group 2 that was 31% (9 out of 29 cases) with p value &lt; 0.0001. The clinical pregnancy rate was also significantly higher in-group 1 (55%) as compared to group 2 (24%) with p value &lt; 0.0001. Limitations, reasons for caution Further larger cohort studies are required to explore the subcutaneous role of G CSF in thin endometrium. Wider implications of the findings: Granulocyte colony-stimulating factor has beneficial role to improve the endometrium thickness in thin endometrium. In most of previous studies, the intrauterine infusion of G CSF was given to improve the uterine lining. This is one of the few studies done that showed subcutaneous role of G CSF in thin endometrium. Trial registration number Not applicable

Background: Treatment-resistant thin endometrium (TTE) during in-vitro fertilization is a relatively uncommon and challenging problem. Objective: The primary aim of the study was to assess the TTE rate during frozen embryo transfer (FET) cycles and the secondary aim was to evaluate the effect of intrauterine instillation of granulocyte colony stimulating factor (G-CSF) in these cases. Materials and Methods: In this cross-sectional study, all of the women who underwent FET cycles with hormonal endometrial preparation in Royan Institute from June 2015 to March 2018 were evaluated and all of the cases with TTE diagnosis (endometrial thickness < 7 mm after using high doses of estradiol) were included. In the eligible cases, 300 μgr of G-CSF was infused intrauterine. If the endometrium had not reached at least a 7-mm, a second infusion was prescribed within 48 hr later. Results: During the study, 8,363 of FET cycles were evaluated and a total of 30 infertile patients (0.35%) with TTE diagnosis were detected. Finally, 20 eligible patients were included. The changes of endometrial thickness after G-CSF therapy were significant (p< 0.001); however, the endometrial thickness did not reach 7 mm in nine patients (45%) and the embryo transfer was canceled. Conclusion: It was found that the rate of TTE during the FET cycle is very low and intrauterine perfusion of G-CSF has a potential effect to increase the endometrial thickness in these patients; however, the rate of cancellation was still high and poor pregnancy outcomes were observed.

Background: Granulocyte-colony stimulating factor (G-CSF) is an innovative therapy in reproductive medicine. Although its mechanisms of action have remained unknown, G-CSF seems to be effective in the case of recurrent abortion or implantation failure and thin endometrium. Objectives: This study was conducted to investigate whether subcutaneous administration of G-CSF has any effect on pregnancy outcome after assisted reproductive technology (ART). Methods: Fifty women with male infertility factors undergoing ART treatment were enrolled and stimulated with the standard long protocol. The G-CSF group of women received one dose of subcutaneous G-CSF (Filgrastim, 300 µg/1 mL) on the day of embryo transfer and again two days later while the placebo group received normal saline. Results: Seventeen patients had a positive β-human chorionic gonadotropin concentration after embryo transfer (8 and 9 in G-CSF and placebo groups, respectively) although the difference was not statistically significant. In addition, spontaneous abortion occurred in three patients (1 patient in the G-CSF group vs. 2 patients in the placebo group). Conclusion: Overall, although G-CSF failed to affect the endometrial thickness, as well as implantation, or clinical pregnancy rates, a lower prevalence of abortion in G-CSF group may be due to the positive effect of G-CSF administration on the endometrium as compared to the placebo group.
