Abstract Aims: Granulocyte colony–stimulating factor (G-CSF) has raised much interest due to its role to cocaine addiction in preclinical models. We analyzed the circulating expression of G-CSF in abstinent chronic users of alcohol and/or cocaine with or without comorbid major depressive disorders to investigate the role of this trophic factor with complicated substance use disorders.Methods: We recruited 176 patients and 136 controls. Patients were divided in 50 patients with major depressive disorder (MDD) and 126 abstinent substance use disorders (SUD) patients undergoing treatments for alcohol (N=66) or cocaine (N=60) addiction according to DSM-IV-TR criteria. A blood sample was collected to examine plasma concentrations of G-CSF.Results: The plasma concentrations of G-CSF were significantly decreased in the cocaine group compared with the SUD control group. There was a sex dimorphism in the alcohol group, with lower G-CSF concentrations in women compared with men. Plasma concentrations of G-CSF were associated with abstinence and with the length of alcohol problems. The decrease in G-CSF was associated with comorbid MDD, a finding specific for SUD patients since there were no alterations of G-CSF primary settings MDD outpatients.Conclusions: Circulating G-CSF is reduced in SUD patients, being associated to comorbid MDD. A sex-dependent effect was observed in female AUD. Plasma G-CSF concentrations might be used as a predictor of length of chronic alcohol use and as a stratification role in the dual diagnosis in SUD. Further investigation is needed to explore the role of G-CSF as potential biomarker of pathogenic/prognosis in SUD population.

AbstractGranulocyte colony–stimulating factor (G-CSF) has raised much interest because of its role in cocaine addiction in preclinical models. We explored the plasma concentrations of G-CSF in patients diagnosed with substance use disorder (SUD) and highly comorbid psychiatric disorders. In particular, we investigated the association between G-CSF concentrations and comorbid major depressive disorder (MDD) in patients with cocaine and alcohol use disorders (CUD and AUD, respectively). Additionally, patients with MDD but not SUD were included in the study. Three hundred and eleven participants were enrolled in this exploratory study: 136 control subjects, 125 patients with SUD (SUD group) from outpatient treatment programs for cocaine (N = 60, cocaine subgroup) and alcohol (N = 65, alcohol subgroup), and 50 patients with MDD but not SUD (MDD group) from primary-care settings. Participants were assessed based on DSM-IV-TR criteria, and a blood sample was collected to examine the plasma concentrations of G-CSF. G-CSF concentrations were negatively correlated with age in the entire sample (r = − 0.233, p < 0.001) but not in the patients with MDD. G-CSF concentrations were lower in patients with SUD than in controls (p < 0.05), specifically in the cocaine subgroup (p < 0.05). Patients with SUD and comorbid MDD had lower G-CSF concentrations than patients with SUD but not comorbid MDD or controls (p < 0.05). In contrast, patients with MDD but not SUD showed no differences compared with their controls. The negative association between G-CSF concentrations and age in the sample was not observed in patients with MDD. G-CSF concentrations were decreased in patients with SUD and comorbid MDD but not in patients with MDD. Therefore, G-CSF may be useful to improve the stratification of patients with dual diagnosis seeking treatment. Further investigation is needed to explore the impact of sex and type of drug on the expression of G-CSF.

Cortisol Release

Under stressful conditions, the hypothalamic-pituitary-adrenal (HPA) axis acts to promote transitory physiological adaptations that are often resolved after the stressful stimulus is no longer present. In addition to corticosteroids (e.g., cortisol), the neurosteroid allopregnanolone (3α,5α-tetrahydroprogesterone, 3α-hydroxy-5α-pregnan-20-one) participates in negative feedback mechanisms that restore homeostasis. Chronic, repeated exposure to stress impairs the responsivity of the HPA axis and dampens allopregnanolone levels, participating in the etiopathology of psychiatric disorders, such as major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). MDD and PTSD patients present abnormalities in the HPA axis regulation, such as altered cortisol levels or failure to suppress cortisol release in the dexamethasone suppression test. Herein, we review the neurophysiological role of allopregnanolone both as a potent and positive GABAergic neuromodulator but also in its capacity of inhibiting the HPA axis. The allopregnanolone function in the mechanisms that recapitulate stress-induced pathophysiology, including MDD and PTSD, and its potential as both a treatment target and as a biomarker for these disorders is discussed.

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

Multiple hematopoietic cytokines can stimulate granulopoiesis; however, their relative importance in vivo and mechanisms of action remain unclear. We recently reported that granulocyte colony-stimulating factor receptor (G-CSFR)-deficient mice have a severe quantitative defect in granulopoiesis despite which phenotypically normal neutrophils were still detected. These results confirmed a role for the G-CSFR as a major regulator of granulopoiesis in vivo, but also indicated that G-CSFR independent mechanisms of granulopoiesis must exist. To explore the role of interleukin-6 (IL-6) in granulopoiesis, we generated IL-6 × G-CSFR doubly deficient mice. The additional loss of IL-6 significantly worsened the neutropenia present in young adult G-CSFR–deficient mice; moreover, exogenous IL-6 stimulated granulopoiesis in vivo in the absence of G-CSFR signals. Near normal numbers of myeloid progenitors were detected in the bone marrow of IL-6 × G-CSFR–deficient mice and their ability to terminally differentiate into mature neutrophils was observed. These results indicate that IL-6 is an independent regulator of granulopoiesis in vivo and show that neither G-CSFR or IL-6 signals are required for the commitment of multipotential progenitors to the myeloid lineage or for their terminal differentiation.

OBJECTIVE: To investigate in a community sample the association of suicide-related cognitions and behaviors ("thoughts of death", "desire for death", "suicidal thoughts", and "suicidal attempts") with the comorbidity of depressive disorders (major depressive episode or dysthymia) and alcohol or substance use disorders. METHOD: The sample was 1464 subjects interviewed in their homes using the Composite International Diagnostic Interview to generate DSM-III-R diagnosis. Descriptive statistics depicted the prevalence of suicide-related cognitions and behaviors by socio-demographic variables and diagnoses considered (major depressive episode, dysthymia, alcohol or substance use disorders). We performed a multivariate logistic regression analysis to estimate the effect of comorbid major depressive episode/dysthymia and alcohol or substance use disorders on each of the suicide-related cognitions and behaviors. RESULTS: The presence of major depressive episode and dysthymia was significantly associated with suicide-related cognitions and behaviors. In the regression models, suicide-related cognitions and behaviors were predicted by major depressive episode (OR = range 2.3-9.2) and dysthymia (OR = range 5.1-32.6), even in the presence of alcohol use disorders (OR = range 2.3-4.0) or alcohol or substance use disorders (OR = range 2.7-2.8). The interaction effect was observed between major depressive episode and alcohol use disorders, as well as between dysthymia and gender. Substance use disorders were excluded from most of the models. CONCLUSION: Presence of major depressive episode and dysthymia influences suicide-related cognitions and behaviors, independently of the presence of alcohol or substance use disorders. However, alcohol use disorders and gender interact with depressive disorders, displaying a differential effect on suicide-related cognitions and behaviors.
