Risk of psychiatric disorders in patients taking isotretinoin: A nationwide, population-based, cohort study in Taiwan. J Affect Disord 2022; 296:277-282. [PMID: 34628248 DOI: 10.1016/j.jad.2021.09.055] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 09/06/2021] [Accepted: 09/16/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND After isotretinoin's approval to treat patients with recalcitrant acne, there have been continued debates around its psychiatric safety profile. This study aimed to assess the risk of psychiatric disorders in patients with acne who are taking isotretinoin. METHODS We used de-identified information from Taiwan's National Health Insurance Research Database from 2000 to 2015 to examine the risk for psychiatric disorders among patients with acne who were taking isotretinoin. We performed subgroup analyses based on the dosage and duration of isotretinoin administration. RESULTS This study included 29,943 participants during a 16-year follow-up period. We found no significantly increased risk for psychiatric disorders among patients taking isotretinoin compared with patients who did not receive isotretinoin treatment (adjusted hazard ratio [aHR]: 1.009, 95% confidence interval [CI]: 0.422-1.696). Subgroup analyses showed no significantly increased risk for psychiatric disorders in patients taking different doses of isotretinoin (≤ 20 mg per day, aHR: 0.892, 95% CI: 0.371-1.501; > 20 mg per day, aHR: 1.068, 95% CI: 0.446-1.798). There was also no significant increase in risk for patients undergoing isotretinoin treatment over different periods (≤ 6 months, aHR: 0.924, 95% CI: 0.392-1.612; > 6 months, aHR: 1.196, 95% CI: 0.488-2.004). LIMITATIONS We did not analyze the risk of suicidal ideation, and it could be underestimated in medical claims databases. CONCLUSIONS We found no increased risk of psychiatric disorders among Taiwanese patients with acne who were taking isotretinoin. Higher dosage or longer duration of isotretinoin treatment did not increase the risk for developing a psychiatric disorder.

Abstract
Background Isotretinoin (13-cis-retinoic acid, marketed under the names Accutane, Roaccutane, and others) is an effective treatment for acne that has been on the market for over 30 years, although reports of neuropsychiatric side effects continue to be reported. Isotretinoin is an isomer of the active form of Vitamin A, 13-trans-retinoic acid, which has known psychiatric side effects when given in excessive doses, and is part of the family of compounds called retinoids, which have multiple functions in the central nervous system. Methods The literature was reviewed in pubmed and psychinfo for research related to isotretinoin and neuropsychiatric side effects including depression, suicidal thoughts, suicide, mania, anxiety, impulsivity, emotional lability, violence, aggression, and psychosis. Results Multiple case series have shown that successful treatment of acne with isotretinoin results in improvements in measures of quality of life and self esteem However, studies show individual cases of clinically significant depression and other neuropsychiatric events that, although not common, are persistent in the literature. Since the original cases of depression were reported to the United States Food and Drug Administration, numerous cases have been reported to regulatory agencies in the United Kingdom, France, Ireland, Denmark, Australia, Canada, and other countries, making isotretinoin one of the top five medications in the world associated with depression and other neuropsychiatric side effects. Clinicians are advised to warn patients of the risks of neuropsychiatric side effects with isotretinoin which may arise from the medication itself, and not just as a side effect of acne or youth.

Abstract
Isotretinoin, an active form of vitamin A, is the drug of last resort for the treatment of severe acne. Depression, suicidal ideation, and psychosis are among the most well-documented psychiatric side effects. Here, we report a case of isotretinoin-induced psychosis, which was diagnosed as delusional disorder somatic subtype, in a young male in the absence of any prodromal symptoms, previous psychiatric history, or family history of mental illness. The onset of psychosis was in the context of a dosage increase from 40 mg/day to 80 mg/day. Isotretinoin was discontinued, and the patient showed improvement on low-dose quetiapine.

Abstract
Isotretinoin, a synthetic vitamin A derivative, is primarily used in the
management of severe nodulocystic acne. Since its introduction, isotretinoin has
been linked with various psychiatric side effects. In particular, depression and
suicidality have been extensively reported as side effects. This case report
features a young male who developed a first psychotic episode within 3 months of
starting isotretinoin therapy. The patient was hospitalized, and organic
pathologies and use of psychoactive substances that could explain his
presentation were ruled out. After stopping isotretinoin and starting olanzapine
10 mg, the psychotic symptoms remitted completely within 2 weeks. This case
highlights the need for increased vigilance toward psychiatric manifestations of
isotretinoin. In addition, it suggests that secondary psychosis should be
considered as a differential diagnosis by clinicians, especially in patients
with no past psychiatric history or family history of mental illness.

Abstract
Novel targets for depression and anxiety disorders are necessary for the development of more effective pharmacotherapeutics. Our previous study found that the retinoic acid (RA) signaling pathway is the signaling pathway most enhanced in the nucleus accumbens (NAc) shell, a region important for depression, anxiety, and addiction. Genetic manipulations of RA signaling in the NAc affecting addiction-related behavior prompted our study of the role of retinoic acid signaling in depression-related and anxiety-related behavior using in vivo RNA interference. Knockdown of the retinoic acid degradation enzyme cytochrome p450 family 26 subfamily b member 1 (Cyp26b1) in the nucleus accumbens shell increased depression-related behavior while decreasing anxiety-like behavior. Knockdown of the retinoic acid binding protein, cellular RA binding protein 2 (Crabp2), also increased depression-related behavior. Knockdown of another RA binding partner fatty acid binding protein 5 (Fabp5), did not alter these behaviors. These results further support the contention that RA signaling in the NAc shell can affect emotional behavior and that targeting some components of this pathway could be a promising avenue for developing novel treatments for depression and anxiety.

Abstract
Isotretinoin teratogenicity well established; psychiatric effects documented, controversial Disturbed retinoid signaling implicated in isotretinoin teratogenic and psychiatric effects Effect of genetics on susceptibility to psychiatric side effects is possible, not yet known Postnatal neurocognitive effects of isotretinoin not yet established
Background An association between isotretinoin (13-cis-retinoic acid, sold under trade names including Accutane [Hoffmann-La Roche Inc, Basel, Switzerland]) and birth defects, depression, and suicide is well documented but controversial. A link to psychosis and exacerbation of bipolar symptoms is less extensively addressed in the literature. Objective Given recent conceptualization of psychotic disorders as neurodevelopmental, and current interest in possible shared etiology of different neurodevelopmental disorders such as psychosis, autism, and intellectual disability, this review concurrently examines the literature on developmental (primarily teratogenic) and psychiatric side effects of isotretinoin exposure. The goal of concurrent review is to identify shared mechanisms in the literature that may inform future efforts to clarify the neurocognitive and psychiatric effects of isotretinoin exposure at different developmental stages or given different genetic backgrounds. Methods Literature was obtained by PubMed search for the term isotretinoin in combination with each of the terms psychosis, psychiatric, and teratogenic. Resulting articles met inclusion criteria for review if they addressed psychiatric side effects of isotretinoin treatment or the neurobehavioral teratology of isotretinoin. Results The association of isotretinoin exposure with prenatal developmental toxicity is well established. Although numerous reports also link isotretinoin treatment with psychiatric side effects, this association remains controversial. Conclusions The extent to which isotretinoin influences pediatric and adult development and cognition, and whether and why certain individuals may be susceptible to psychiatric side effects, remains to be clarified.

Abstract
BACKGROUND The link between isotretinoin, treatment of a severe form of acne, and psychiatric disorders remains controversial, as acne itself could explain the occurrence of psychiatric disorders. This study aims at assessing the disproportionality of psychiatric adverse events reported with isotretinoin in the French National PharmacoVigilance Database, compared with other systemic acne treatments and systemic retinoids. MATERIALS AND METHODS Data were extracted from the French National PharmacoVigilance Database for systemic acne treatments, systemic retinoids and drugs used as comparators. Each report was subjected to double-blind analysis by two psychiatric experts. A disproportionality analysis was performed, calculating the number of psychiatric ADRs divided by the total number of notifications for each drug of interest. RESULTS Concerning acne systemic treatments: all 71 reports of severe psychiatric disorders involved isotretinoin, the highest proportion of mild/moderate psychiatric adverse events was reported with isotretinoin (14.1%). Among systemic retinoids, the highest proportion of severe and mild/moderate psychiatric events occurred with isotretinoin and alitretinoin. CONCLUSION Our study raises the hypothesis that psychiatric disorders associated with isotretinoin are related to a class effect of retinoids, as a signal emerges for alitretinoin. Complementary studies are necessary to estimate the risk and further determine at-risk populations.

Abstract
OBJECTIVE To analyse cases of 9 patients (18-27 yo) who were consequently admitted to our department and treated with affective disorders (AD) while undergoing isotretinoin (INN) therapy. METHODS A semi-structured questionnaire designed by the authors was used to analyse many variables related to demographic characteristics, dermatologic and psychiatrics symptoms, AD course and treatment, family history of mental disorders, building on medical histories of patients and their families, and available medical records. RESULTS Patients were diagnosed (DSM-IV-TR) with: a major depressive episode (4 patients), a recurrent major depressive episode (3), a bipolar mixed episode (1), and rapid cycling bipolar I disorder (1). The mean time from the first use of INN to: I. the onset of mental disorders was approximately 2 months (1-6 months), II. a visit with a psychiatrist was about 12 months (1-38 months). The predictors of occurrence of AD included a family history of AD and a prior episode of mental disorders. The onset of AD was in most cases preceded by prodromal symptoms such as headaches, sleep disorders, fatigue, drowsiness, or general weakness. Five patients reported suicidal ideation, four patients showed suicidal tendencies, and two persons attempted to commit suicide during the treatment. CONCLUSIONS Psychiatrists should pay special attention to isotretinoin as a drug that may trigger episodes of AD, particularly in patients with a family history of AD or prior episodes of mental disorders. Isotretinoin therapy of patients with acne and a family history of AD or prior episodes of mental disorders requires special care and, if symptoms of depression develop or worsen during the INN treatment, collaboration between a dermatologist and a psychiatrist is needed.

Abstract
Isotretinoin (Accutane) is a treatment for severe acne that is resistant to other forms of treatment, including antibiotics and topical treatments. The prescription of this drug has been controversial ever since its initial marketing in 1982. It is the only non-psychotropic drug in the Food and Drug Administration top 10 drugs found to be associated with depression. Recently, Bremner et al published an extensive review (until 2010) of the evidence for the association of retinoic acid (RA) with depression and suicide. Some patients who are admitted in psychiatric hospitals report a history of present or past treatment with isotretinoin. Then, the imputability of the molecule in the occurrence of disorders represents necessarily an important question for both professionals and their patients. This paper aims to specify the links between the drug and specific psychiatric disorders. A review of the literature related to isotretinoin, RA, vitamin A, depression, suicide, anxiety, bipolar disorder, psychosis, schizophrenia was performed. Many studies demonstrated an increased risk of depression, attempted suicide and suicide following isotretinoin treatment. However, isotretinoin may have an antidepressant impact, according to some dermatological papers. They consider treating acne with this efficient treatment could improve self-image and make the patient feel better. Several studies showed that patients with bipolar disorder had an increased risk for a clinical exacerbation of symptoms undergoing treatment with isotretinoin. A few studies also seem to suggest a possible link between isotretinoin and psychosis. Nonetheless, studies point out a link between retinoid dysregulation and schizophrenia through modulation of dopamine receptors. From this review, we propose guidelines for isotretinoin prescription to healthcare professionals.

Abstract
Isotretinoin is used for the treatment of severe acne. Psychiatric side-effects, particularly depression, have been well-documented. This dramatic case report is about a young male patient who developed acute psychosis within a few days of starting isotretinoin. Due to his persecutory delusions, the patient, who was an Indian engineer working in Germany, decided to immediately return to India fearing for his life in Germany. Careful history taking established the cause of the psychosis. Isotretinoin was stopped; patient showed rapid improvement, within a week, on a low dose of risperidone. Risperidone was continued as a precaution for 3 months. After a further 8 months, the patient remains well without any psychotropic medication.

Abstract
Postpartum depression (PPD) is an international public health problem affecting at least 1 in 8 mothers. Known risk factors include: giving birth to a preterm or low birth weight infant, babies with greater symptoms of illness at age 4-6 weeks, formula feeding, younger maternal age, smoking, and fatigue. Prolonged breastfeeding is associated with a reduced risk of PPD but the mechanisms are not well understood. Interventions for PPD focusing on psychosocial risk factors have been largely unsuccessful, suggesting that the condition has a mainly biological basis. The hypothesis proposed for consideration is that breastfeeding protects against PPD by maintaining endogenous retinoids (vitamin A-related compounds) below a threshold concentration. In fact, breast milk is rich in retinoids; pregnant women accumulate retinoids in liver and breast in preparation for lactation; there is increasing evidence that retinoids in higher concentration are associated with cognitive disturbances and mood disorders, including depression and suicide; and prolonged lactation reduces maternal stores of retinoids. Consistent with this hypothesis, it is estimated that an amount of vitamin A is transferred from mother to infant during the first six months of exclusive breastfeeding equivalent to 76% of a dose known to cause acute vitamin A poisoning in an adult. Breastfeeding may thus have evolutionary-adaptive functions for both mother and infant, transferring vital nutrients to an infant unable to feed itself, yet at the same time providing a natural means of reducing potentially toxic concentrations of retinoids in the mother.

Abstract
Mefloquine use has been linked to severe gastrointestinal and neuropsychiatric adverse effects, including cognitive disturbances, anxiety, depression, psychosis, and violence. The adverse effects of the drug are thought to result from the secondary consequences of hepatocellular injury; in fact, mefloquine is known to cause a transient, anicteric chemical hepatitis. However, the mechanism of mefloquine-associated liver damage and the associated neuropsychiatric and behavioral effects of the drug are not well understood. Mefloquine and other 8-amino-quinolines are the only antimalarial drugs that target the liver-stage malaria parasites, which selectively absorb vitamin A from the host. Vitamin A is also stored mainly in the liver, in potentially poisonous concentrations. These observations suggest that both the therapeutic effectiveness of mefloquine and its adverse effects are related to the ability of the 8-aminoquinolines to alter the metabolism of retinoids (vitamin A and its congeners). Several lines of evidence support the hypothesis that mefloquine neurotoxicity and other adverse effects reflect an endogenous form of hypervitaminosis A due to a process involving: mefloquine-induced dehydrogenase inhibition; the accumulation of retinoids in the liver; retinoid-induced hepatocellular damage; the spillage of stored retinoids into the circulation; and the transport of these compounds to the gut and brain in toxic concentrations. The retinoid hypothesis could be tested clinically by comparing cases of mefloquine toxicity and untreated controls in terms of retinoid profiles (retinol, retinyl esters, percent retinyl esters, and retinoic acid). Subject to such tests, retinoid profiling could provide an indicator for assessing mefloquine-associated adverse effects.

Abstract
BACKGROUND Depression and mood changes appear as potentional side effects of isotretinoin in the Summary of Product Characteristics. There have been many studies treating this topic but in most cases not identifying any significant depression or suicide risk. To further investigate this issue, we conducted a prospective, uncontrolled study to evaluate mood changes and suicidal ideations in patients receiving isotretinoin therapy. METHODS One-hundred patients were included in our single center, no-blind, and no controlled prospective study. All patients completed the Beck's Depression Inventory, Version II (BDI-II) before the treatment, following the first month of the treatment and then every third month until finishing the isotretinoin therapy. All questionnaires were checked by a psychiatrist. Suicidal ideations were monitored. Statistical analysis of BDI-II scores was performed. RESULTS All patients completed the study. Before the treatment, six percent of the patients had suffered from depressive symptoms. During the isotretinoin treatment, we did not find any deterioration of depression problems in any of these patients. On the contrary, in most patients the depressive symptoms disappeared. Symptoms of depression occurred in two patients, in which case coexisting situational factors were found to be the cause. No occurrence of suicidal ideations was found. CONCLUSIONS We did not find any depressive symptoms or suicide risk caused by isotretinoin. On the contrary, a statistically significant improvement of BDI-II scores was found. In our opinion, patients have to be informed about the risk of depression but emphasizing the fact that it is very rare.

Abstract
OBJECTIVE Isotretinoin (13-cis-retinoic acid), approved by the US Food and Drug Administration for the treatment of acne, carries a black box warning related to the risk of depression, suicide, and psychosis. Retinoic acid, the active form of vitamin A, regulates gene expression in the brain, and isotretinoin is its 13-cis isomer. Retinoids represent a group of compounds derived from vitamin A that perform a large variety of functions in many systems, in particular the central nervous system, and abnormal retinoid levels can have neurologic effects. Although infrequent, proper recognition and treatment of psychiatric side effects in acne patients is critical given the risk of death and disability. This article reviews the evidence for isotretinoin's relationships with depression and suicidality. DATA SOURCES The PsycINFO, MEDLINE, and PubMed searchable database indexes were searched for articles published in the English language from 1960 to June 2010 using the key words isotretinoin, retinoids, retinoic acid, depression, depressive disorders, and vitamin A. Evidence examined includes (1) case reports; (2) temporal association between onset of depression and exposure to the drug; (3) challenge-rechallenge cases; (4) class effect (other compounds in the same class, like vitamin A, having similar neuropsychiatric effects); (5) dose response; and (6) biologically plausible mechanisms. STUDY SELECTION All articles in the literature related to isotretinoin, depression, and suicide were reviewed, as well as articles related to class effect, dose response, and biologic plausibility. DATA EXTRACTION Information from individual articles in the literature was extracted, including number of episodes of depression, suicidality, suicide, psychosis, violence and aggression, past psychiatric history, time of onset in relation to isotretinoin usage, medication dosage, duration of treatment, and dechallenge and challenge history. RESULTS The literature reviewed is consistent with associations of isotretinoin administration with depression and with suicide in a subgroup of vulnerable individuals. CONCLUSIONS The relationship between isotretinoin and depression may have implications for a greater understanding of the neurobiology of affective disorders.

Abstract
Retinoids, a family of molecules that is derived from vitamin A, are involved in a complex signaling pathway that regulates gene expression and controls neuronal differentiation in the central nervous system. The physiological actions of retinoids are mainly mediated by retinoic acid receptors. Here we describe the distribution of retinoic acid receptor α (RARα) in the human hypothalamus by immunohistochemistry. RARα immunoreactivity showed a widespread pattern throughout the hypothalamus, with high density in the suprachiasmatic nucleus (SCN), paraventricular nucleus (PVN), supraoptic nucleus (SON), infundibular nucleus and medial mamillary nucleus. No staining was observed in the sexually dimorphic nucleus of preoptic area, tuberomamillary nucleus and lateral hypothalamic area. RARα was co-localized with vasopressin (AVP) neurons in the SCN, PVN and SON, and co-localized with corticotropin releasing hormone (CRH) neurons in the PVN. These findings provide a neurobiological basis for the participation of retinoids in the regulation of various hypothalamic functions. As shown earlier, the co-localization of RARα in CRH neurons suggests that retinoids might directly modulate the hypothalamus-pituitary-adrenal axis in the PVN, which may have implications for the stress response and its involvement in mood disorders. Functional studies in the other sites of RARα localization have to follow in the future.

Abstract
Isotretinoin, a drug used for moderate to severe acne, has been repeatedly associated with various psychiatric complications, although a definitive causal relationship has not been established to date. This case report describes a 25-year-old male who developed obsessive-compulsive disorder at the age of 23 years following isotretinoin treatment for acne (10-20 mg/day) since the age of 16 years. Although standard treatment for obsessive-compulsive disorder caused mood swings, the combination of fluvoxamine 300 mg/day and olanzapine 15 mg/day significantly improves the clinical picture. Although rare, severe adulthood psychiatric complications may occur following isotretinoin treatment, requiring management which is individually tailored to the patient.

Abstract
BACKGROUND Isotretinoin (Accutane(R)) has been available for the treatment of severe cystic acne for about twenty-five years. There have been several reports of adverse psychiatric reactions to isotretinoin, including depressive symptoms and suicide. However, there have been only three case reports of patients with bipolar disorder (BD) who experienced an untoward psychiatric side effect while receiving isotretinoin treatment. In this study, the psychiatric side effects from isotretinoin were assessed in a larger group of BD patients than has previously been reported. METHODS A retrospective chart review of 300 BD outpatients identified ten patients treated with isotretinoin. RESULTS Nine of these ten patients experienced a significant worsening of mood symptoms, and three developed suicidal ideation. Eight experienced a reversal of the relapsed mood symptoms when the isotretinoin was discontinued, whether prematurely or after a full course. LIMITATIONS The limitations of this study include small sample size, retrospective data collection, absence of double-blind controlled design, and inability to control for spontaneous mood episodes in patients with BD. CONCLUSIONS These results indicate that BD patients treated with isotretinoin for acne are at risk for clinically significant exacerbation of mood symptoms, including suicidal ideation, even with concurrent use of psychiatric medicines for BD. The clinical implications of this study are especially relevant to the treatment of patients with BD because acne usually occurs during adolescence, which is often the age of onset of BD and because a common side effect of lithium (a standard treatment for BD) is acne.

Abstract
Retinoids, vitamin A related compounds, have an established role in the development of the nervous system and are increasingly recognized to play a role in adult brain function. The synthetic retinoid, 13-cis-retinoic acid (13-cis-RA, Roaccutane) is widely used to treat severe acne but has been linked to an increased risk of neuropsychiatric side effects, including depression. Here we report that chronic administration with 13-cis-RA (1 mg/kg i.p. daily, 7-14 days) in adult rats reduced aggression- and increased flight-related behaviours in the resident-intruder paradigm. However, in the forced swim, sucrose consumption and open field tests treatment for up to 6 weeks with 13-cis-RA did not modify behaviour in adult or juvenile animals. The behavioural change observed in the resident-intruder paradigm is directly opposite to that observed with chronic antidepressant administration. These findings indicate that when a suitably sensitive behavioural test is employed then chronic administration of 13-cis-RA in adult rats induces behavioural changes consistent with a pro-depressant action.

Abstract
BACKGROUND Corticotropin-releasing hormone (CRH) is considered the central driving force in the stress response and plays a key role in the pathogenesis of depression. Retinoic acid (RA) has been suggested by clinical studies to be associated with affective disorders. METHODS First, hypothalamic tissues of 12 patients with affective disorders and 12 matched control subjects were studied by double-label immunofluorescence to analyze the expression of CRH and retinoic acid receptor-alpha (RAR-alpha). Second, critical genes involved in the RA signaling pathways were analyzed in a rat model of depression. Finally, the regulatory effect of RAR-alpha on CRH gene expression was studied in vitro. RESULTS We found that the expression of RAR-alpha was colocalized with CRH neurons in human hypothalamic paraventricular nucleus (PVN). The density of RAR-alpha-immunoreactive neurons and CRH-RAR-alpha double-staining neurons was significantly increased in the PVN of patients with affective disorders. The ratio of the CRH-RAR-alpha double-staining neurons to the CRH-immunoreactive neurons in affective disorder patients was also increased. Recruitment of RAR-alpha by the CRH promoter was observed in the rat hypothalamus. A dysregulated RA metabolism and signaling was also found in the hypothalamus of a rat model for depression. Finally, in vitro studies demonstrated that RAR-alpha mediated an upregulation of CRH gene expression. CONCLUSIONS These results suggest that RAR-alpha might contribute to regulating the activity of CRH neurons in vivo, and the vulnerable character of the critical proteins in RA signaling pathways might provide novel targets for therapeutic strategies for depression.

Abstract
Isotretinoin, a synthetic oral retinoid that is used against severe nodulocystic acne, has been associated with various psychiatric side effects such as depression, suicidality and psychotic symptoms. A great number of reports on its effects have been published since its introduction into the market. However, a causal relationship has not been established and the link between isotretinoin use and psychiatric events remains controversial. The present paper reviews the available evidence regarding the association of isotretinoin and psychiatric side effects. All published material reporting psychiatric side effects following isotretinoin treatment, including case reports, case series, reports from adverse drug event reporting systems, prospective surveys and retrospective case-control studies, are presented. In addition, the neurobiology of the retinoids and possible biological mechanisms that may lead to psychopathology are described.

Abstract
There is extensive evidence that oxidative damage of dopamine (DA)-containing neurons in the substantia nigra pars compacta (SNc) may contribute to the pathogenesis of Parkinson's disease (PD). We evaluated the potential neuroprotective effect of diets enriched with wild-type Red Setter (RS) tomato or transgenic High Carotene (HC) tomato, rich in beta-carotene, obtained by the activation of lycopene beta-cyclase (tlcy-b), in an animal model of PD. Male Fischer 344 rats were fed for 14 days with standard Altromin diet, 5% RS- or 5% HC-enriched diet. Seven days after the beginning of this diet regimen, the rats were lesioned by 6-hydroxydopamine (6-OHDA) injected into the left SNc. After further 7 days, the rats were sacrificed, and DA and 3,4-dihydroxyphenylacetic acid (DOPAC) levels in both the left (ipsilateral) and the right (contralateral) striata were measured. Striatal DA levels were reduced by 86.5 +/- 5.0% in control, 86.2 +/- 5.0% in HC-, and 56.0 +/- 9.0% in RS-fed group. Striatal DOPAC was decreased by 85.6 +/- 5.0% in controls, 83.0 +/- 6.0% in HC-, and 58.9 +/- 10.0% in RS-fed group. Blood was obtained from the rats on day 14 and the plasma level of licopene and beta-carotene was measured by liquid chromatography-atmospheric pressure chemical ionization-mass spectrometry (LC-APCI-MS) for the determination of lycopene and beta-carotene levels. The plasma level of lycopene was 4.7 +/- 0.2 ng/ml in 5% RS-fed rats, while it was undetectable (< 2.5 ng ml(-1)) in control and HC-fed rats. The efficacy of RS diet to preserve striatal dopaminergic innervation can be attributed to the ability of lycopene to prevent the degeneration of DA-containing neurons in the SNc.

Abstract
Current models of affective disorders implicate alterations in norepinephrine, serotonin, dopamine, and CRF/cortisol; however treatments targeted at these neurotransmitters or hormones have led to imperfect resolution of symptoms, suggesting that the neurobiology of affective disorders is incompletely understood. Until now retinoids have not been considered as possible contributors to affective disorders. Retinoids represent a family of compounds derived from vitamin A that perform a large number of functions, many via the vitamin A product, retinoic acid. This signaling molecule binds to specific retinoic acid receptors in the brain which, like the glucocorticoid and thyroid hormone receptors, are part of the nuclear receptor superfamily and regulate gene transcription. Research in the field of retinoic acid in the CNS has focused on the developing brain, in part stimulated by the observation that isotretinoin (13-cis retinoic acid), an isomer of retinoic acid used in the treatment of acne, is highly teratogenic for the CNS. More recent work has suggested that retinoic acid may influence the adult brain; animal studies indicated that the administration of isotretinoin is associated with alterations in behavior as well as inhibition of neurogenesis in the hippocampus. Clinical evidence for an association between retinoids and depression includes case reports in the literature, studies of health care databases, and other sources. A preliminary PET study in human subjects showed that isotretinoin was associated with a decrease in orbitofrontal metabolism. Several studies have shown that the molecular components required for retinoic acid signaling are expressed in the adult brain; the overlap of brain areas implicated in retinoic acid function and stress and depression suggest that retinoids could play a role in affective disorders. This report reviews the evidence in this area and describes several systems that may be targets of retinoic acid and which contribute to the pathophysiology of depression.

Abstract
Retinoid signaling plays a well-established role in neuronal differentiation, neurite outgrowth, and the patterning of the anteroposterior axis of the developing neural tube. However, there is increasing evidence that nutritional vitamin A status and retinoid signaling play an important role in the function of the adult brain. 13-Cis-retinoic acid (13-cis-RA) (isotretinoin or Accutane), a synthetic retinoid that is an effective oral treatment for severe nodular acne, has been linked with depression and suicide in patients. The purpose of this study was to test the hypothesis that chronic administration of 13-cis-RA would lead to depression-related behaviors in mice. Young, adult male mice received 13-cis-RA (1 mg/kg) by daily intraperitoneal injection for 6 weeks. This treatment paradigm produced plasma levels of 13-cis-RA that are comparable to those reported in human patients taking Accutane. In both the forced swim test and the tail suspension test, we found that 13-cis-RA-treated mice spent significantly more time immobile compared to vehicle-treated controls. In the open field test, there was no change in anxiety-related behavior in 13-cis-RA-treated mice. Furthermore, chronic administration of 13-cis-RA did not impair locomotion in either the open field or the rotarod test. Taken together, these results suggest that administration of 13-cis-RA increases depression-related behaviors in mice.

Abstract
BACKGROUND The association between exposure to Isotretinoin, the development of depression and suicide attempts is controversial. OBJECTIVE To retrospectively assess pattern of utilization of mental health services in the Israeli Defense Forces (IDF) during a 5-year period for all subjects exposed to Isotretinoin in comparison to a control group consisting of army conscripts suffering from psoriasis. All subjects were young adults (18 to 21 years old) in compulsory military service. METHOD Exposure to Isotretinoin mandates reporting and marking as a coded medical profile in the IDFs' computerized medical record of each conscript and soldier. Medical data, tracked by military medical profiles, were summarized from medical records of all subjects treated by Isotretinion during the years 1999-2003 and for the control group for the same period. Use of mental health services was the a-priori defined primary outcome measure. RESULTS During the study period 1419 subjects were exposed to Isotretinoin and 1102 suffered from psoriasis. Utilization of mental health services was highest for the index group wherein 17.2% (245/1419) of subjects were evaluated or treated compared to 12.5% in the control group (psoriasis). The inter-group differences were statistically significant; Chi-square=15.9 (df=2), p=0.0003. CONCLUSIONS We suggest that psychiatric evaluation be regularly undertaken prior to initiation of Isotretinion treatment in young adults at risk, as well as providing follow-up visits during and at completion of treatment.

Abstract
Acne is a common disorder that may have a considerable psychologic impact including anxiety and depression. Depression and suicide occur frequently in adolescents and young adults. Although case reports suggest an association between isotretinoin and depression and suicide, more rigorous observational studies and epidemiologic studies, using different designs, have not shown any effect of isotretinoin use in increasing the occurrence of depression and suicide. It is prudent for the practitioner to continue to use isotretinoin to treat severe acne, while at the same time informing patients and their relatives that depressive symptoms should be actively assessed at each visit and, if necessary, referral to a psychiatrist and a discontinuation of isotretinoin should be considered.
