McGuirt AF, Brezing CA. Opioid-induced hypogonadism in opioid use disorder, its role in negative reinforcement, and implications for treatment and retention. THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2024; 50:132-138. [PMID: 38320237 DOI: 10.1080/00952990.2023.2292012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 12/03/2023] [Indexed: 02/08/2024]
Abstract
Hypogonadism is a highly prevalent complication of chronic opioid use associated with a constellation of affective, algesic, and cognitive symptoms as well as decreased quality of life. Given that the mainstays of pharmacologic opioid use disorder (OUD) treatment - methadone and buprenorphine - are themselves agonists or partial agonists at the mu opioid receptor, opioid-induced hypogonadism (OIH) remains an underappreciated clinical concern throughout the course of OUD treatment. Prominent theoretical frameworks for OUD emphasize the importance of negative reinforcement and hyperkatifeia, defined as the heightened salience of negative emotional and motivational states brought on by chronic opioid use. In this perspective article, we highlight the striking parallels between the symptom domains of hyperfakifeia and hypogonadism in males, who comprise the vast majority of existing clinical research on OIH. By extension we propose that future research and ultimately clinical care should focus on the identification and treatment of OIH in OUD patients to help address the longstanding paradox of poor treatment retention despite efficacious therapies, particularly in the setting of the current opioid overdose epidemic driven by high potency synthetic opioids such as fentanyl. We then review evidence from chronic pain patients that testosterone replacement provides clinically significant benefits to men with OIH. Finally, using this framework, we compare extant OUD therapeutics and discuss critical gaps in the clinical literature-including the relative dearth of data regarding hypothalamic-pituitary-gonadal function in females who use opioids-where future study should be focused.

Abstract
Anabolic androgenic steroids (AAS) have medical utility but are often abused, and the effects of AAS on reward circuits in the brain have been suggested to lead to addiction. We investigated the previously reported correlations between AAS and the endogenous μ-opioid system in the rewarding properties of AAS in mice. We found that a single injection of a supraphysiological dose of natural or synthetic AAS strengthened excitatory synaptic transmission in putative ventral tegmental area (VTA) dopaminergic neurons. This effect was associated with the activation of μ-opioid receptors (MORs) and an increase in β-endorphins released into the VTA and the plasma. Irreversible blockade of MORs in the VTA counteracted two drug-seeking behaviors, locomotor activity and place preference. These data suggest that AAS indirectly stimulate a dopaminergic reward center of the brain through activation of endogenous opioid signaling and that this mechanism mediates the addictive effects of AAS.

Abstract
Male Syrian hamsters (Mesocricetus auratus) administered anabolic/androgenic steroids during adolescent development display increased aggression and decreased anxious behavior during the adolescent exposure period. Upon withdrawal from anabolic/androgenic steroids, this neurobehavioral relationship shifts and hamsters exhibit decreased aggression and increased anxious behavior. This study investigated the hypothesis that alterations in anterior hypothalamic signaling through serotonin type-3 receptors modulate the behavioral shift between adolescent anabolic/androgenic steroid-induced aggressive and anxious behaviors during the withdrawal period. To test this, hamsters were administered anabolic/androgenic steroids during adolescence then withdrawn from drug exposure for 21 days and tested for aggressive and anxious behaviors following direct pharmacological manipulation of serotonin type-3 receptor signaling within the latero-anterior hypothalamus. Blockade of latero-anterior hypothalamic serotonin type-3 receptors both increased aggression and decreased anxious behavior in steroid-treated hamsters, effectively reversing the pattern of behavioral responding normally observed during anabolic/androgenic steroid withdrawal. These findings suggest that the state of serotonin neural signaling within the latero-anterior hypothalamus plays an important role in behavioral shifting between aggressive and anxious behaviors following adolescent exposure to anabolic/androgenic steroids.

Abstract
Cannabis is the most commonly used illicit drug worldwide. Although its use is associated with multiple adverse health effects, including the risk of developing addiction, recreational and medical cannabis use is being increasing legalized. In addition, use of synthetic cannabinoid drugs is gaining considerable popularity and is associated with mass poisonings and occasional deaths. Delineating factors involved in cannabis use and addiction therefore becomes increasingly important. Similarly to other drugs of abuse, the prevalence of cannabis use and addiction differs remarkably between males and females, suggesting that sex plays a role in regulating cannabinoid sensitivity. Although it remains unclear how sex may affect the initiation and maintenance of cannabis use in humans, animal studies strongly suggest that endogenous sex hormones modulate cannabinoid sensitivity. In addition, synthetic anabolic-androgenic steroids alter substance use and further support the importance of sex steroids in controlling drug sensitivity. The recent discovery that pregnenolone, the precursor of all steroid hormones, controls cannabinoid receptor activation corroborates the link between steroid hormones and the endocannabinoid system. This article reviews the literature regarding the influence of endogenous and synthetic steroid hormones on the endocannabinoid system and cannabinoid action.

Abstract
Adolescent Syrian hamsters (Mesocricetus auratus) treated with anabolic/androgenic steroids display increased offensive aggression and decreased anxiety correlated with an increase in vasopressin afferent development, synthesis, and neural signaling within the anterior hypothalamus. Upon withdrawal from anabolic/androgenic steroids, this neurobehavioral relationship shifts as hamsters display decreased offensive aggression and increased anxiety correlated with a decrease in anterior hypothalamic vasopressin. This study investigated the hypothesis that alterations in anterior hypothalamic vasopressin neural signaling modulate behavioral shifting between adolescent anabolic/androgenic steroid-induced offensive aggression and anxiety. To test this, adolescent male hamsters were administered anabolic/androgenic steroids and tested for offensive aggression or anxiety following direct pharmacological manipulation of vasopressin V1A receptor signaling within the anterior hypothalamus. Blockade of anterior hypothalamic vasopressin V1A receptor signaling suppressed offensive aggression and enhanced general and social anxiety in hamsters administered anabolic/androgenic steroids during adolescence, effectively reversing the pattern of behavioral response pattern normally observed during the adolescent exposure period. Conversely, activation of anterior hypothalamic vasopressin V1A receptor signaling enhanced offensive aggression in hamsters exposed to anabolic/androgenic steroids during adolescence. Together, these findings suggest that the state of vasopressin neural development and signaling in the anterior hypothalamus plays an important role in behavioral shifting between aggression and anxiety following adolescent exposure to anabolic/androgenic steroids.

Abstract
RATIONALE For several decades, elite athletes and a growing number of recreational consumers have used anabolic androgenic steroids (AAS) as performance enhancing drugs. Despite mounting evidence that illicit use of these synthetic steroids has detrimental effects on affective states, information available on sex-specific actions of these drugs is lacking. OBJECTIVES The focus of this review is to assess information to date on the importance of sex and its interaction with other environmental factors on affective behaviors, with an emphasis on data derived from non-human studies. METHODS The PubMed database was searched for relevant studies in both sexes. RESULTS Studies examining AAS use in females are limited, reflecting the lower prevalence of use in this sex. Data, however, indicate significant sex-specific differences in AAS effects on anxiety-like and aggressive behaviors, interactions with other drugs of abuse, and the interplay of AAS with other environmental factors such as diet and exercise. CONCLUSIONS Current methods for assessing AAS use have limitations that suggest biases of both under- and over-reporting, which may be amplified for females who are poorly represented in self-report studies of human subjects and are rarely used in animal studies. Data from animal literature suggest that there are significant sex-specific differences in the impact of AAS on aggression, anxiety, and concomitant use of other abused substances. These results have relevance for human females who take these drugs as performance-enhancing substances and for transgender XX individuals who may illicitly self-administer AAS as they transition to a male gender identity.

Abstract
BACKGROUND Most studies on anabolic-androgenic steroids abuse have been done in adult rats, but few data are available to immature. OBJECTIVE This study was conducted to assay the effect of Nandrolone Decanoate (ND) on the testis and testosterone concentration in male immature rats compare with mature ones in short and long time. MATERIALS AND METHODS 40 mature rats were divided into 4 groups: group A (short term) and group B (long-term) received 10 mg/kg/day ND interaperitoneally for 35 and 70 days, respectively. Group C (control) without any treatment, and group D (vehicle) received dimethyl sulfoxide (DMSO) solution in two periods 35 and 70 days. 40 immature rats were divided into 4 groups same as mature ones. After surgery body weight, testis size, histomorphometry of testis, and serum testosterone level were evaluated. RESULTS Our results showed that ND decreased the number of Leydig cells in group B (39.9 ±. 919), group A (43.4 ±. 120), and long term (40.6 ±. 299) immature rats, which could result in a reduction of testosterone concentration significantly in all experimental groups except short term mature group. Number of sertoli cells, testis size, and diameter of seminiferous tubules decreased in the long-term immature group. Eventually, the number of sperm was decreased in mature and immature groups, but a severe depletion of sperm was occurred in both mature and immature in long time in comparison to the control group (p< 0.05). CONCLUSION This time course study showed that supraphysiological dose of ND may negatively affect the number of Leydig cells, sperm cell, and testosterone concentration of immature rats in the same matter of mature rats. However, the number of sertoli cell, testis size, and seminferous diameter were decreased only in the long immature rats.

Abstract
Androgens are mainly prescribed to treat several diseases caused by testosterone deficiency. However, athletes try to promote muscle growth by manipulating testosterone levels or assuming androgen anabolic steroids (AAS). These substances were originally synthesized to obtain anabolic effects greater than testosterone. Although AAS are rarely prescribed compared to testosterone, their off-label utilization is very wide. Furthermore, combinations of different steroids and doses generally higher than those used in therapy are common. Symptoms of the chronic use of supra-therapeutic doses of AAS include anxiety, depression, aggression, paranoia, distractibility, confusion, amnesia. Interestingly, some studies have shown that AAS elicited electroencephalographic changes similar to those observed with amphetamine abuse. The frequency of side effects is higher among AAS abusers, with psychiatric complications such as labile mood, lack of impulse control and high violence. On the other hand, AAS addiction studies are complex because data collection is very difficult due to the subjects' reticence and can be biased by many variables, including physical exercise, that alter the reward system. Moreover, it has been reported that AAS may imbalance neurotransmitter systems involved in the reward process, leading to increased sensitivity toward opioid narcotics and central stimulants. The goal of this article is to review the literature on steroid abuse and changes to the reward system in preclinical and clinical studies.

Abstract
Testosterone influences the brain via organizational and activational effects. Numerous relevant studies on rodents and a few on humans focusing on specific behavioral and cognitive parameters have been published. The results are, unfortunately, controversial and puzzling. Dosing, timing, even the application route seem to considerably affect the outcomes. In addition, the methods used for the assessment of psychometric parameters are a bit less than ideal regarding their validity and reproducibility. Metabolism of testosterone contributes to the complexity of its actions. Reduction to dihydrotestosterone by 5-alpha reductase increases the androgen activity; conversion to estradiol by aromatase converts the androgen to estrogen activity. Recently, the non-genomic effects of testosterone on behavior bypassing the nuclear receptors have attracted the interest of researchers. This review tries to summarize the current understanding of the complexity of the effects of testosterone on brain with special focus on their role in the known sex differences.

Abstract
Adolescents and adults engage in anabolic-androgenic steroid (AAS) misuse seeking their anabolic effects, even though later on, many could develop neuropsychological dependence. Previously, we have shown that nandrolone induces conditioned place preference (CPP) in adult male mice. However, whether nandrolone induces CPP during adolescence remains unknown. In this study, the CPP test was used to determine the rewarding properties of nandrolone (7.5 mg/kg) in adolescent mice. In addition, since D1 dopamine receptors (D1DR) are critical for reward-related processes, the effect of nandrolone on the expression of D1DR in the nucleus accumbens (NAc) was investigated by Western blot analysis. Similar to our previous results, nandrolone induced CPP in adults. However, in adolescents, nandrolone failed to produce place preference. At the molecular level, nandrolone decreased D1DR expression in the NAc only in adult mice. Our data suggest that nandrolone may not be rewarding in adolescents at least during short-term use. The lack of nandrolone rewarding effects in adolescents may be due, in part to differences in D1DR expression during development.

Abstract
In the U.S. and worldwide anabolic/androgenic steroid use remains high in the adolescent population. This is concerning given that anabolic/androgenic steroid use is associated with a higher incidence of aggressive behavior during exposure and anxiety during withdrawal. This study uses pubertal Syrian hamsters (Mesocricetus auratus) to investigate the hypothesis that an inverse behavioral relationship exists between anabolic/androgenic steroid-induced aggression and anxiety across adolescent exposure and withdrawal. In the first experiment, we examined aggression and anxiety during adolescent anabolic/androgenic steroid exposure and withdrawal. Adolescent anabolic/androgenic steroid administration produced significant increases in aggression and decreases in anxiety during the exposure period followed by significant decreases in aggression and increases in anxiety during anabolic/androgenic steroid withdrawal. In a second experiment, anabolic/androgenic steroid exposed animals were separated into groups based on their aggressive response during the exposure period and then tested for anxiety during exposure and then for both aggression and anxiety during withdrawal. Data were analyzed using a within-subjects repeated measures predictive analysis. Linear regression analysis revealed that the difference in aggressive responding between the anabolic/androgenic steroid exposure and withdrawal periods was a significant predictor of differences in anxiety for both days of testing. Moreover, the combined data suggest that the decrease in aggressive behavior from exposure to withdrawal predicts an increase in anxiety-like responding within these same animals during this time span. Together these findings indicate that early anabolic/androgenic steroid exposure has potent aggression- and anxiety-eliciting effects and that these behavioral changes occur alongside a predictive relationship that exists between these two behaviors over time.

Abstract
Aging is usually associated with a progressive disruption of the redox balance leading to recurrent damage resulting from oxidative stress. Oxidative stress resulting from excessive free-radical release is likely implicated in the initiation and progression of motor behavior disorders. Therefore, antioxidant therapies have received considerable attention in motor behavior defects treatment. The nuclear factor erythroid 2-related factor 2 (Nrf2) binds to antioxidant response element (ARE) to induce antioxidant and phase II detoxification enzymes under conditions of oxidative stress, which reduces oxidative stress and accumulation of toxic metabolites. Testosterone has many physiological and behavioral effects throughout the lifespan and shown to affect motor behavior in adult male rats and gonadectomized rats. However, whether Nrf2-ARE pathway is activated after testosterone administration has not been studied in aged rats. The tilting-plane test and the horizontal-wire test as well as the oxidative stress parameters, the expression of Nrf2, heme oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase-1 (NQO1) and the number of tyrosine hydroxylase immunoreactive (TH-ir) cells in brain were examined in aged rats following chronic subcutaneous injections of testosterone propionate (TP). Our study showed that chronic TP supplement significantly ameliorated the decline of balancing reactions and muscular strength associated with aging. Oxidative stress parameters were ameliorate, the expression of Nrf2, HO-1 and NQO1 at protein or gene levels and the number of TH-ir cells significantly increased in substantia nigra or caudate putamen after TP treatment in aged rats. Our findings demonstrated that chronic TP treatment activated Nrf2-ARE pathway may influence the maintenance of the balancing reactions and muscular strength and reduce TH-ir cells death in aged rats. Therefore, TP supplement have shown for therapeutic strategies in the treatment and modification of motor behavior disorders.

Ricci LA, Morrison TR, Melloni RH. Serotonin modulates anxiety-like behaviors during withdrawal from adolescent anabolic-androgenic steroid exposure in Syrian hamsters. Horm Behav 2012; 62:569-78. [PMID: 23026540 PMCID: PMC3612524 DOI: 10.1016/j.yhbeh.2012.09.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2012] [Revised: 09/20/2012] [Accepted: 09/21/2012] [Indexed: 12/27/2022]
Abstract
From the U.S. to Europe and Australia anabolic steroid abuse remains high in the adolescent population. This is concerning given that anabolic steroid use is associated with a higher incidence of pathological anxiety that often appears during withdrawal from use. This study uses pubertal Syrian hamsters (Mesocricetus auratus) to investigate the hypothesis that adolescent anabolic/androgenic steroid (AAS) exposure predisposes hamsters to heightened levels of anxiety during AAS withdrawal that is modulated by serotonin (5HT) neural signaling. In the first two sets of experiments, adolescent AAS-treated hamsters were tested for anxiety 21 days after the cessation of AAS administration (i.e., during AAS withdrawal) using the elevated plus maze (EPM), dark/light (DL), and seed finding (SF) tests and then examined for differences in 5HT afferent innervation to select areas of the brain important for anxiety. In the EPM and DL tests, adolescent AAS exposure leads to significant increases in anxiety-like response during AAS withdrawal. AAS-treated hamsters showed long-term reductions in 5HT innervation within several areas of the hamster brain implicated in anxiety, most notably the anterior hypothalamus and the central and medial amygdala. However, no differences in 5HT were found in other anxiety areas, e.g., frontal cortex and lateral septum. In the last experiment, adolescent AAS-treated hamsters were scored for anxiety on the 21st day of AAS withdrawal following the systemic administration of saline or one of three doses of fluoxetine, a selective serotonin reuptake inhibitor. Saline-treated hamsters showed high levels of AAS withdrawal-induced anxiety, while treatment with fluoxetine reduced AAS withdrawal-induced anxiety. These findings indicate that early AAS exposure has potent anxiogenic effects during AAS withdrawal that are modulated, in part, by 5HT signaling.

Abstract
OBJECTIVE Little is known about anabolic androgenic steroids (AAS) misuse in the Caribbean region in spite of increased popularity among athletes and adolescents. The present study examines the usage of AAS among competitive athletes in Puerto Rico. METHODS Doping test results of competitive athletes obtained by random sampling out of competition during the 2000-2009 period were analysed. Doping tests were executed by the Centre for Sports, Health and Exercise Sciences (Albergue Olímpico, Salinas, Puerto Rico). A total of 550 athletes were monitored during 2000-2009. Information was collected with regard to competitive sport, gender and AAS compounds whenever a positive test result was encountered. RESULTS From the total sample of monitored cases during the past decade, 5.4% showed adverse analytical findings. Anabolic androgenic steroids misuse was detected among male (62%) and female (38%) athletes. Weightlifting showed the greatest percentage of positive AAS doping test results (70% of total cases) and stanozolol was the most commonly misused exogenous androgen (60% of abused AAS whether alone or as part of a cocktail). Testosterone was the most common endogenous misused steroid (10% of misused compounds). CONCLUSION In Puerto Rico, AAS misuse was detected across competitive sports for both genders. Although AAS misuse among Puerto Rican athletes shares some features that are consistent with the international sports community, it is imperative to address AAS misuse in the Caribbean region.

Abstract
The neuroactive steroid hormone progesterone attenuates cocaine's abuse-related effects in women and in rodents under some conditions, but the effects of testosterone are unknown. We compared the acute effects of progesterone (0.1, 0.2, and 0.3 mg/kg, intramuscularly (i.m.)), testosterone (0.001, 0.003, and 0.01 mg/kg, i.m.), and placebo on cocaine self-administration and cocaine discrimination dose-effect curves in female rhesus monkeys. Cocaine self-administration (0.03 mg/kg per inj.) was maintained on a fixed ratio 30 schedule of reinforcement, and monkeys had unlimited access to cocaine for 2 h each day. Cocaine doses were administered in an irregular order during each dose-effect curve determination, and the same dose order was used in each subject in all treatment conditions. Blood samples for hormone analysis were collected at the end of each test session. Banana-flavored food pellets (1 g) were also available in three 1-h daily sessions. In drug discrimination studies, the effects of pretreatment with progesterone (0.032-0.32 mg/kg, i.m.) and testosterone (0.001-0.01 mg/kg, i.m.) on the discriminative stimulus effects of cocaine (0.18 mg/kg, i.m.) were examined. Progesterone and testosterone did not alter cocaine discrimination, and did not substitute for cocaine. In contrast, progesterone and testosterone each significantly decreased cocaine self-administration, and produced a downward and rightward shift in the cocaine self-administration dose-effect curve. These findings are concordant with clinical reports that progesterone administration may decrease ratings of positive subjective effects of cocaine in women, and suggest the possible value of neuroactive steroid hormones for the treatment of cocaine abuse and reduction of risk for relapse.

Abstract
AIM The purpose of this study was to provide a quantitative assessment of female rat sexual behaviors after acute exposure to the A-ring reduced testosterone metabolite, androstanediol (3α-Diol), through the nucleus accumbens (NA) shell. MAIN OUTCOME MEASURES Quantitative analyses of female rat sexual behaviors and assessment of protein levels for the enzyme glutamic acid decarboxylase isoform 67 (GAD67) and gephyrin, a protein that participates in the clustering of GABA-A receptors in postsynaptic cells, were accomplished. METHODS Female rats were ovariectomized and primed with estrogen and progesterone to induce sexual behaviors. Females received a 3α-Diol infusion via guided cannula that aimed to the NA shell five minutes prior to a sexual encounter with a stud male. The following parameters were videotaped and measured in a frame by frame analysis: lordosis quotient (LQ), Lordosis rating (LR), frequency and duration of proceptive behaviors (hopping/darting and ear wiggling). Levels of GAD67 and gephyrin were obtained by Western blot analysis two or twenty-four hours after the sexual encounter. RESULTS Acute exposure to 3α-Diol in the NA shell enhanced LR, ear wiggling, and hopping/darting but not LQ. Some of these behavioral effects were counteracted by co-infusion of 3α-Diol plus the GABAA-receptor antagonist GABAzine. A transient reduction of GAD67 levels in the NA shell was detected. CONCLUSIONS The testosterone metabolite 3α-Diol enhances sexual proceptivity, but not receptivity, when infused into the NA shell directly. The GABAergic system may participate in the androgen-mediated enhancement of female rat sexual motivation.
