Psychotic symptoms in bipolar disorder and their impact on the illness: A systematic review. World J Psychiatry 2022; 12:1204-1232. [PMID: 36186500 PMCID: PMC9521535 DOI: 10.5498/wjp.v12.i9.1204] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 05/02/2022] [Accepted: 08/26/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Lifetime psychotic symptoms are present in over half of the patients with bipolar disorder (BD) and can have an adverse effect on its course, outcome, and treatment. However, despite a considerable amount of research, the impact of psychotic symptoms on BD remains unclear, and there are very few systematic reviews on the subject.
AIM To examine the extent of psychotic symptoms in BD and their impact on several aspects of the illness.
METHODS The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. An electronic literature search of six English-language databases and a manual search was undertaken to identify published articles on psychotic symptoms in BD from January 1940 to December 2021. Combinations of the relevant Medical Subject Headings terms were used to search for these studies. Articles were selected after a screening phase, followed by a review of the full texts of the articles. Assessment of the methodological quality of the studies and the risk of bias was conducted using standard tools.
RESULTS This systematic review included 339 studies of patients with BD. Lifetime psychosis was found in more than a half to two-thirds of the patients, while current psychosis was found in a little less than half of them. Delusions were more common than hallucinations in all phases of BD. About a third of the patients reported first-rank symptoms or mood-incongruent psychotic symptoms, particularly during manic episodes. Psychotic symptoms were more frequent in bipolar type I compared to bipolar type II disorder and in mania or mixed episodes compared to bipolar depression. Although psychotic symptoms were not more severe in BD, the severity of the illness in psychotic BD was consistently greater. Psychosis was usually associated with poor insight and a higher frequency of agitation, anxiety, and hostility but not with psychiatric comorbidity. Psychosis was consistently linked with increased rates and the duration of hospitalizations, switching among patients with depression, and poorer outcomes with mood-incongruent symptoms. In contrast, psychosis was less likely to be accompanied by a rapid-cycling course, longer illness duration, and heightened suicidal risk. There was no significant impact of psychosis on the other parameters of course and outcome.
CONCLUSION Though psychotic symptoms are very common in BD, they are not always associated with an adverse impact on BD and its course and outcome.

Effects of gender and psychiatric comorbidity on the age of illness onset and the outcome of psychotic depression-A birth cohort study. J Affect Disord 2022; 296:587-592. [PMID: 34634319 DOI: 10.1016/j.jad.2021.09.077] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 08/28/2021] [Accepted: 09/26/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Psychotic depression (PD) is an under-researched disorder with severe symptoms and course of illness. Little is known about gender differences relating to this condition and possible variation of prognosis based on comorbid pathology. Our aim was to analyze the effects of gender and psychiatric comorbidities on the age of illness onset and on the outcome of psychotic depression. METHODS The study was carried out in the Northern Finland Birth Cohort 1966. We utilized register data to acquire information about lifetime psychiatric diagnoses, hospitalization, age of illness onset, rate of disability pensions and mortality. The PD group (n = 58) was defined based on a lifetime register diagnosis. We compared outcome variables in sub-groups based on gender and comorbid alcohol use or personality disorder. RESULTS The prevalence of comorbid personality disorders was 38% (22/58) and comorbid alcohol use disorders 41% (24/58). PD patients with a personality disorder diagnosis had an earlier onset age (p<0.01) and a higher mortality rate (p = 0.03). Male gender (p = 0.03), comorbid alcohol use disorder (p<0.01) and personality disorder (p < 0.01) were all associated with more psychiatric hospitalization. Comorbid alcohol use disorder was more common among men (males: 61%; females: 29%; p = 0.03). LIMITATIONS National registers were the main source of diagnostic information. CONCLUSIONS Gender and psychiatric comorbidity have significant implications for the course of illness in PD in naturalistic settings, which is an important message for all clinicians. More research into the heterogeneity of PD is needed in order to guide research and clinical practice.

Clinical characteristics and sociodemographic features of psychotic major depression. Ann Gen Psychiatry 2021; 20:24. [PMID: 33771161 PMCID: PMC8004453 DOI: 10.1186/s12991-021-00341-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Accepted: 03/07/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Psychotic major depression (PMD) is a subtype of depression with a poor prognosis. Previous studies have failed to find many differences between patients with PMD and those with non-psychotic major depression (NMD) or schizophrenia (SZ). We compared sociodemographic factors (including season of conception) and clinical characteristics between patients with PMD, NMD, and schizophrenia. Our aim was to provide data to help inform clinical diagnoses and future etiology research. METHODS This study used data of all patients admitted to Shandong Mental Health Center from June 1, 2016 to December 31, 2017. We analyzed cases who had experienced an episode of PMD (International Classification of Diseases, Tenth Revision codes F32.3, F33.3), NMD (F32.0-2/9, F33.0-2/9), and SZ (F20-20.9). Data on sex, main discharge diagnosis, date of birth, ethnicity, family history of psychiatric diseases, marital status, age at first onset, education, allergy history, and presence of trigger events were collected. Odds ratios (OR) were calculated using logistic regression analyses. Missing values were filled using the k-nearest neighbor method. RESULTS PMD patients were more likely to have a family history of psychiatric diseases in their first-, second-, and third-degree relatives ([OR] 1.701, 95% confidence interval [CI] 1.019-2.804) and to have obtained a higher level of education (OR 1.451, 95% CI 1.168-1.808) compared with depression patients without psychotic features. Compared to PMD patients, schizophrenia patients had lower education (OR 0.604, 95% CI 0.492-0.741), were more often divorced (OR 3.087, 95% CI 1.168-10.096), had a younger age of onset (OR 0.934, 95% CI 0.914-0.954), less likely to have a history of allergies (OR 0.604, 95% CI 0.492-0.741), and less likely to have experienced a trigger event 1 year before first onset (OR 0.420, 95% CI 0.267-0.661). Season of conception, ethnicity, and sex did not differ significantly between PMD and NMD or schizophrenia and PMD. CONCLUSIONS PMD patients have more similarities with NMD patients than SZ patients in terms of demographic and clinical characteristics. The differences found between PMD and SZ, and PMD and NMD correlated with specificity of the diseases. Furthermore, allergy history should be considered in future epidemiological studies of psychotic disorders.

Abstract
OBJECTIVE It still remains unclear whether psychotic features increase the risk of suicidal attempts in major depressive disorder. Thus, we attempted, through a systematic review coupled with a meta-analysis, to elucidate further whether unipolar psychotic depression (PMD) compared to non-PMD presents higher levels of suicidal attempts. METHOD A systematic search was conducted in PubMed, EMBASE, PsycINFO as well as in various databases of the so-called gray literature for all studies providing data on suicidal attempts in PMD compared to non-PMD, and the results were then subjected to meta-analysis. RESULTS Twenty studies met our inclusion criteria, including in total 1,275 PMD patients and 5,761 non-PMD patients. An elevated risk for suicide attempt for PMD compared to non-PMD patients was found: The total (lifetime) fixed-effects pooled OR was 2.11 (95% CI: 1.81-2.47), and the fixed-effects pooled OR of the five studies of the acute phase of the disorder was 1.93 (95% CI: 1.33-2.80). This elevated risk of suicidal attempt for PMD patients remained stable across all age groups of adult patients. CONCLUSION Despite data inconsistency and clinical heterogeneity, this systematic review and meta-analysis showed that patients with PMD are at a two-fold higher risk, both during lifetime and in acute phase, of committing a suicidal attempt than patients with non-PMD.

Psychotic (delusional) depression and completed suicide: a systematic review and meta-analysis. Ann Gen Psychiatry 2018; 17:39.

Abstract
BACKGROUND It remains unclear whether psychotic features increase the risk of completed suicides in unipolar depression. The present systematic review coupled with a meta-analysis attempts to elucidate whether unipolar psychotic major depression (PMD) compared to non-PMD presents higher rates of suicides. METHODS A systematic search was conducted in Scopus, PubMed, and "gray literature" for all studies providing data on completed suicides in PMD compared to non-PMD, and the findings were then subjected to meta-analysis. All articles were independently extracted by two authors using predefined data fields. RESULTS Nine studies with 33,873 patients, among them 828 suicides, met our inclusion criteria. PMD compared to non-PMD presented a higher lifetime risk of completed suicides with fixed-effect pooled OR 1.21 (95% CI 1.04-1.40). In a sub-analysis excluding a very large study (weight = 86.62%), and comparing 681 PMD to 2106 non-PMD patients, an even higher pooled OR was found [fixed-effect OR 1.69 (95% CI 1.16-2.45)]. Our meta-analysis may provide evidence that the presence of psychosis increases the risk of suicide in patients suffering from severe depression. The data are inconclusive on the contribution of age, mood congruence, comorbidity, and suicide method on PMD's suicide risk. The lack of accurate diagnosis at the time of suicide, PMD's diagnostic instability, and the use of ICD-10 criteria constitute the main study limitations. CONCLUSIONS The presence of psychosis in major depression should alert clinicians for the increased risk of completed suicide. Thus, the implementation of an effective treatment both for psychotic depression and patients' suicidality constitutes a supreme priority.

Abstract
Research suggests that cognitive and behavioral therapies produce significant benefits over medications alone in the treatment of severe, nonpsychotic major depression or primary psychotic disorders such as schizophrenia. However, previous research has not demonstrated the efficacy of psychotherapy for major depression with psychotic features. In this initial treatment development study, we conducted an open trial of a new behavioral intervention that combines elements of behavioral activation and acceptance and commitment therapy for depression and psychosis. Fourteen patients with major depressive disorder with psychotic features were provided with up to 6 months of Acceptance-Based Depression and Psychosis Therapy (ADAPT) in combination with pharmacotherapy. Patients reported a high degree of treatment credibility and acceptability. Results showed that patients achieved clinically significant and sustained improvements through posttreatment follow-up in depressive and psychotic symptoms, as well as psychosocial functioning. In addition, the processes targeted by the intervention (e.g., acceptance, mindfulness, values) improved significantly over the course of treatment, and changes in processes were correlated with changes in symptoms. Results suggest that ADAPT combined with pharmacotherapy is a promising treatment approach for psychotic depression that should be tested in a future randomized trial.

The effect of severity and personality on the psychotic presentation of major depression. Psychiatry Res 2011; 190:98-102.

Abstract
The aim of the present study was to evaluate whether symptom severity or personality traits are associated with psychotic symptoms in major depression (MD), since it is still debated whether psychotic depression represents the most severe form of depression or the effect of personality structure. The study included 163 patients affected by MD who were divided into four groups on the basis of the presence/absence of melancholic features and psychotic symptoms. All subjects completed the Structured Clinical Interview for DSM-IV Disorders (SCID-IV), the Structured Clinical Interview for DSM-IV Personality Disorders (SIDP-IV) and the Hamilton Rating Scale for Depression (Ham-D). Personality was assessed after MD remission (absence of DSM-IV criteria and Ham-D score lower than 7 for at least 2 months). Psychotic symptoms were positively associated with symptom severity (higher Ham-D total score) and with paranoid and schizotypal traits and negatively related to histrionic traits. Our data support the view that the effect of paranoid-schizotypal traits and symptom severity on the presence of psychotic symptoms in MD occurs separately and they are independent of each other.

Abstract
Major depressive disorder (MDD) with psychotic features is relatively frequent in patients with greater depressive symptom severity and is associated with a poorer course of illness and greater functional impairment than MDD without psychotic features. Multiple studies have found that patients with psychotic mood disorders demonstrate significantly poorer cognitive performance in a variety of areas than those with nonpsychotic mood disorders. The Mini Mental State Examination (MMSE) and the Dementia Rating Scale, Second Edition (DRS-2) are widely used to measure cognitive functions in research on MDD with psychotic features. Established total raw score cut-offs of 24 on the MMSE and 137 on the DRS-2 in published manuals suggest possible global cognitive impairment and dementia, respectively. Limited research is available on these suggested cut-offs for patients with MDD with psychotic features. We document the therapeutic benefit of electroconvulsive therapy (ECT), which is usually associated with short-term cognitive impairment, in a 68-year-old woman with psychotic depression whose MMSE and DRS-2 scores initially suggested possible global cognitive impairment and dementia. Over the course of four ECT treatments, the patient's MMSE scores progressively increased. After the second ECT treatment, the patient no longer met criteria for global cognitive impairment. With each treatment, depression severity, measured by the 24-item Hamilton Rating Scale for Depression, improved sequentially. Thus, the suggested cut-off scores for the MMSE and the DRS-2 in patients with MDD with psychotic features may in some cases produce false-positive indications of dementia.

Abstract
The presence of comorbidity in major psychoses (e.g., schizophrenia and psychotic subtypes of bipolar disorder and major depressive disorder) seems to be the rule rather than the exception in both DSM-IV and ICD-10. Examining comorbidity in major psychoses, however, requires an investigation into the different levels of comorbidity (either full-blown and subsyndromal) which should be analyzed in both psychopathological and medical fields. On one hand, the high prevalence of psychiatric comorbidity in major psychoses may be the result of the current nosographic systems. On the other hand, it may stem from a common neurobiological substrate. In fact, comorbid psychopathological conditions may share a biological vulnerability, given that dysfunction in specific brain areas may be responsible for different symptoms and syndromes. The high rates of comorbidity in major psychoses require targeted pharmacological treatments in order to effectively act on both the primary diagnosis and comorbid conditions. Nevertheless, few controlled trials in comorbid major psychoses had been carried out and treatment recommendations in this field have mostly an empirical basis. The aim of the present article is to provide a comprehensive and updated overview in relation to epidemiological and clinical issues of comorbidity in major psychoses.

Abstract
The purpose of this study was to examine the trait impulsivity of patients with a major depressive disorder and to explore the possible connections between impulsivity and clinical and sociodemographic variables. The sociodemographic and clinical properties of 60 patients with major depression, who were euthymic according to Hamilton Depression Scale scores, were recorded. Their trait impulsivity was evaluated using the Barratt Impulsiveness Scale (BIS-11) and the impulsivity subscale of the Temperament and Character Inventory, and the results were compared with those of 50 age- and sex-matched healthy controls. We used general linear model analysis to evaluate the manner in which the variables contributed to BIS-11 scores. Some impulsivity scores were higher in those with a major depressive disorder than in comparison subjects. There were significant effects of education and sex in these differences. Elevated BIS-11 scores were associated with a history of psychotic mood episode and suicide attempts. These relationships persisted when age, sex, and education were taken into account. These results show that, after accounting for common confounding factors, trait-like impulsivity was substantially higher in subjects with major depressive disorder than in comparison subjects and may be associated with sociodemographic and clinical properties.

Is depression severity the sole cause of psychotic symptoms during an episode of unipolar major depression? A study both between and within subjects. J Affect Disord 2009; 114:103-9.

Abstract
BACKGROUND Despite the common clinical assumption that psychosis is an indicator of severity in depression, it is not known what determines the presence of psychotic features in major depression. Our aim was to answer the question: Is depression severity the sole cause of psychotic symptoms during an episode of unipolar major depression? METHODS In a sample of 585 patients from the UK, meeting criteria for both DSM-IV and ICD-10 major recurrent depression, we assessed measures of severity of depression and the presence of psychotic features, both within and between subjects. RESULTS Within patients, psychotic episodes tended to be more severe than non-psychotic episodes. However, between patients there was wide variation in severity in both those that did, and did not, experience psychotic episodes. LIMITATIONS We used retrospective interview information together with case note data. Our cases may not be typical of usual case loads because they were selected to avoid family history of bipolar illness or schizophrenia. CONCLUSIONS Individuals with a predisposition to psychotic features tend to display such features during more severe episodes of depression. However, patients with no history of psychosis may experience non-psychotic depressive episodes of equal or greater severity, in terms of depressive symptomatology, compared to patients with psychotic depression. Thus, there is individual variation in susceptibility to psychosis during mood episodes and severity is not the sole determinant.

Abstract
BACKGROUND Psychotic major depression (PMD) is a severe mental disorder characterized by high levels of illness severity, chronicity, impairment, and treatment resistance. However, most past research on PMD has been conducted in inpatient hospital samples, and relatively little is known about PMD patients presenting for treatment in the community specifically. METHODS In this study, we examined the prevalence and clinical characteristics of PMD in a large sample (n=2,500) of treatment-seeking outpatients who were administered structured clinical interviews by trained diagnosticians. RESULTS Of the patients diagnosed with major depression, 5.3% had psychotic features. PMD patients were more likely to be members of a racial/ethnic minority and to have lower educational attainment compared to those with nonpsychotic major depression. In addition, PMD patients were found to have greater current depression severity, suicidal ideation, and social and work impairment. These patients also were more likely to have histories of suicide attempts and psychiatric hospitalizations, to report an earlier age of illness onset, and to meet criteria for chronic depression. In terms of psychiatric comorbidity, PMD patients had higher rates of certain anxiety disorders as well as more somatoform and cluster A personality disorders. CONCLUSIONS Results indicated that PMD was present in a relatively small percentage of treatment-seeking outpatients but was associated with disproportionately high levels of severity and impairment. Similarities and differences between the current findings and those from past research are discussed, including clinical implications for the identification and treatment of PMD in routine practice settings.

Abstract
BACKGROUND While some prior studies have found higher rates of psychotic depression in those with bipolar disorder or a bipolar relative, others have failed to confirm these observations. We examined the relationship of psychotic depression to polarity in several large familial samples of mood disorder. METHODS A total of 4,724 subjects with major mood disorder in three family studies on the genetics of bipolar I disorder (BPI) or recurrent major depressive disorder (MDDR) were administered semi-structured interviews by clinicians. Determination of psychotic features was based on a report of hallucinations and/or delusions during the most severe depressive episode in the Schedule for Affective Disorders and Schizophrenia-Lifetime Version or the Diagnostic Interview for Genetic Studies interview. Rates of psychotic depression were calculated by diagnostic category and comparisons were made between diagnoses within and across studies using the generalized estimating equation. RESULTS A diagnosis of BPI disorder was strongly predictive of psychotic features during depression compared to MDDR [odds ratio (OR) = 4.61, p < 0.0005]. Having bipolar II compared to MDDR was not predictive of psychosis (OR = 1.05, p = 0.260), nor was having a family history of BPI in MDDR subjects (OR = 1.20, p = 0.840). CONCLUSIONS Psychotic features during a depressive episode increased the likelihood of a BPI diagnosis. Prospective studies are needed to confirm these findings. The potential genetic underpinnings of psychotic depression warrant further study.

Abstract
BACKGROUND Psychotic depression is a relatively prevalent mood disorder associated with greater symptom severity, a poorer course of illness and higher levels of functional impairment compared with nonpsychotic depression. Separate lines of investigation suggest that various forms of cognitive-behavioral therapy are efficacious for treating severe forms of nonpsychotic depression as well as primary psychotic disorders. However, there currently are no empirically supported psychotherapies specifically designed for treating psychotic depression. METHOD We review the efficacy of current somatic treatments for the disorder and discuss the limited data to date on potentially useful psychotherapeutic approaches. In particular, we describe the clinical improvement observed in a subgroup of hospitalized patients with psychotic depression treated with Acceptance and Commitment Therapy as part of a larger clinical trial. RESULTS Pilot results demonstrated that Acceptance and Commitment Therapy was associated with clinically significant reductions in acute symptom severity and impairment compared with treatment as usual. CONCLUSION The findings suggest that patients with psychotic depression can benefit from psychotherapy. Clinical and research recommendations in this area are presented.

Abstract
Previous research suggests that psychotic major depression (PMD) is associated with greater illness severity and functional impairment as well as poorer treatment response to antidepressants and psychotherapies compared with nonpsychotic major depression. Although patients with PMD exhibit a number of neurobiological abnormalities, little research has been conducted to date on possible psychological factors that are related to illness in this depression subtype. In the current study, baseline data were pooled from 2 clinical trials in which depressed patients (n = 235) were recruited during a psychiatric hospitalization for an acute episode. Twelve percent (n = 28) of this treatment-seeking sample met criteria for PMD and showed elevated levels of depression severity and dysfunctional beliefs compared with individuals with nonpsychotic major depression. However, even after controlling for depression severity and other relevant baseline variables, only a measure of common dysfunctional beliefs differentiated those with vs those without psychotic features. Furthermore, higher levels of depressive cognitions were related to poorer psychosocial functioning and suicidality in PMD patients. Results suggest that elevated levels of common negative cognitions in depressed patients may be associated with the presence of more severe psychotic symptoms. Adapted cognitive-behavioral treatments may be useful for treating patients with PMD specifically.

Abstract
In bipolar depression, psychomotor agitation is relatively common and often is associated with other noneuphoric hypomanic symptoms and suicidal ideation. Our goal in this retrospective study was to ascertain the co-occurrence of agitation, bipolar features, and suicidal ideation in unipolar disorder. We retrospectively evaluated 314 inpatients with DSM-IV major depressive disorder (MDD) and no other Axis I diagnosis with the National Institutes of Mental Health (NIMH) Life Chart Method and the Operational Criteria for Psychotic Illness (OPCRIT) checklist to ascertain their symptom profiles across all episodes. Univariate and multivariate comparisons were performed between the subgroups with and without psychomotor agitation (OPCRIT item 23> or =1). Agitated depression (AD, a major depressive episode with psychomotor agitation) was present in 19% of the sample. Compared to nonagitated counterparts, patients with AD were older and had lower educational levels and more dysphoria, insomnia, positive thought disorder, and psychotic manifestations. Hypomanic symptoms other than agitation were relatively uncommon (<10%) and more represented in subjects with AD. No significant differences emerged between AD and control groups with respect to most bipolar validators (gender, familiarity, recurrence). Patients with AD had higher levels of suicidal ideation than non-AD controls; however, such a difference was no longer significant after controlling for psychotic features. Excessive self-reproach, early awakening, diurnal changes, poor appetite, and hypomanic symptoms were independently associated with suicidal thoughts in nonpsychotic MDD. Incomplete information on drug treatment, exclusion of patients with Axis I comorbidity, and tertiary care setting were the most important limitations of the study. Although we failed to support the bipolar nature of MDD-AD by common validators, probably because we used a more heterogeneous definition of agitation compared to similar studies, our data confirm the association of agitation with hypomanic symptoms and suicidal thoughts in major depression, and emphasize the complex phenomenology of AD in an inpatient setting.

Abstract
OBJECTIVE To obtain a comprehensive view of the clinical epidemiology of bipolar I and II disorder in secondary-level psychiatric settings. METHODS In the Jorvi Bipolar Study (JoBS), 1630 non-schizophrenic psychiatric in- and outpatients in three Finnish cities were screened for bipolar I and II disorders with the Mood Disorder Questionnaire. Diagnoses were made using semistructured SCID-I and -II interviews. Information collected included clinical history, current episode, symptom status, and other characteristics. RESULTS A total of 191 patients with bipolar disorder (90 bipolar I and 101 bipolar II) were included in the JoBS. The majority of bipolar II (50.5%) and many bipolar I (25.6%) patients were previously undiagnosed; the remainder had a median 7.8 years delay from first episode to diagnosis. Despite several lifetime episodes, 26 and 58% of bipolar I and II patients, respectively, had never been hospitalized. A polyphasic episode was current in 51.3%, rapid cycling in 32.5%, and psychotic symptoms in 16.2% of patients. Mixed episodes occurred in 16.7% of bipolar I, and depressive mixed states in 25.7% of bipolar II patients. CONCLUSION Even in psychiatric settings, bipolar disorders usually go undetected, or recognized only after a long delay. A significant proportion of not only bipolar II, but also bipolar I patients are never hospitalized. Polyphasic episodes and rapid cycling are prevalent in both types. Depressive mixed states are at least as common among bipolar II patients as mixed episodes among bipolar I.

Depressive syndrome in major psychoses: a study on 1351 subjects. Psychiatry Res 2004; 127:85-99.

Abstract
The aim of this study was to investigate depressive symptomatology across distinct major psychiatric disorders. A total of 1351 subjects affected by major depressive disorder (MDD = 389), bipolar disorder (BP = 511), delusional disorder (DD = 93) and schizophrenia (SKZ = 358) were included in our study. Subjects were assessed using the Operational Criteria for Psychotic Illness checklist (OPCRIT). The most frequently represented depressive symptoms in MDD were Loss of energy/tiredness, Loss of pleasure, Poor concentration, and Sleep disorders. Compared with MDD, BP had higher occurrences of Agitated activity, Excessive sleep, and Increased appetite and/or Weight gain, as well as lower Loss of pleasure. In our sample, 32.3% and 26.8% of DD and SKZ, respectively, had quite consistent depressive symptomatology, with at least four or more depressive symptoms. The most common depressive symptoms were Sleep disorders, Poor concentration and Loss of energy/Tiredness, followed by Psychomotor symptoms in SKZ only. Excessive self-reproach, Suicidal ideation, and Appetite and/or Weight changes were more specific to mood disorders. Finally, compared with SKZ, DD suffered from more depressive symptoms and had more severe depressive symptomatology. A quite consistent level of depressive symptomatology is therefore present in subpopulations of delusional and schizophrenic subjects other than in affective subjects. We identified some symptoms that are common across all major psychoses and symptoms that are more specific to each group.

A retrospective comparison of inpatients with mixed and pure depression. Psychopathology 2003; 36:292-8.

Abstract
Some authors advocate a broadening of the narrow concept of mixed episodes in the direction of mania leading to the concept of mixed mania, and in the direction of depression leading to the concept of mixed depression. The latter has been little investigated so far. In the present article, we retrospectively compare 49 patients with pure depression with 51 patients with mixed depression in terms of socio-demographic and clinical variables in order to contribute to the validation of the distinction between mixed and pure depression. Supporting this distinction, we observed that mixed depressive patients more frequently had past histories of bipolar disorder and alcohol abuse and had longer durations of hospital stay. These last two points remain significant even when we control for the effect of the association with bipolarity.

Abstract
The present study investigated possible clinical differences between bipolar patients with and without manic or hypomanic switch during antidepressant (AD) treatment. The authors undertook a retrospective assessment of 169 individuals affected by bipolar disorder type I (BP I: n=96) and II (BP II: n=73) who experienced at least one manic or hypomanic episode following depression without any interposed normothymic period ("manic switch") during AD therapy. They were compared with a sex, age (+/-5 years), and ethnicity-matched group of 247 subjects, randomly selected from our pool of bipolar subjects who have never had manic switches. Only 2 of the 169 patients had had spontaneous switches before the AD-related one. Switched subjects were marginally older (t=-2.65, df=414, P=.008) compared to not switched and less frequently delusional (chi2=13.86, P=.0002). Polarity of the onset episode was more frequently depressive in switched patients (chi2=21.93, P=.00002), which had also less previous manic episodes than not switched (t=3.44, df=332, P=.0006). Those differences were more pronounced in the BP I subsample. Switched patients were more frequently BP I (chi2=29.66; P<.00001). Maintenance with mood stabilizers appears to be a strong protective factor; in fact, of the 124 individuals undertaking a mood stabilizer therapy, 21 had a switch and 103 had no switches (chi2=41.10, P<.000001). In conclusion, some clinical variables, such as the number of manic episodes, the presence of delusions, the polarity of onset episode, and the mood-stabilizing treatment, may be involved in AD-related switches. Further studies are required to investigate the causal relationships between those factors.

Abstract
The aim of this study was to investigate demographic, clinical and symptomatologic features of the following mood disorder subtypes: bipolar disorder I (BP-I); bipolar disorder II (BP-II); major depressive disorder, recurrent (MDR); and major depressive episode, single episode (MDSE). A total of 1832 patients with mood disorders (BP-I=863, BP-II=141, MDR=708, and MDSE=120) were included in our study. The patients were assessed using structured diagnostic interviews and the operational criteria for psychotic illness checklist (n=885), the Hamilton depression rating scale (n=167), and the social adjustment scale (n=305). The BP-I patients were younger; had more hospital admissions; presented a more severe form of symptomatology in terms of psychotic symptoms, disorganization, and atypical features; and showed less insight into their disorder than patients in the other groups. Compared with the major depressive subgroups, BP-I patients were more likely to have an earlier age at onset, an earlier first lifetime psychiatric treatment, and a greater number of illness episodes. BP-II patients had a higher suicide risk than both BP-I and MDSE patients. MDSE patients presented less severe symptomatology, lower age at observation, and a higher number of males. The retrospective approach and the selection constraints due to the inclusion criteria are the main limitations of the study. Our data support the view that BP-I disorder is quite different from the remaining mood disorders from a demographic and clinical perspective, with BP-II disorder having an intermediate position to MDR and MDSE, that is, as a less severe disorder. This finding may help in the search for the biological basis of mood disorders.

Abstract
We studied the possible association between the prophylactic efficacy of lithium in mood disorders and the following gene variants: catechol-O-methyltransferase (COMT) G158A, monoamine oxydase A (MAO-A) 30-bp repeat, G-protein beta 3-subunit (Gbeta3) C825T. A total of 201 subjects affected by bipolar (n = 160) and major depressive (n = 41) disorder were followed prospectively for an average of 59.8 months and were typed for their gene variants using PCR techniques. COMT, MAO-A, and Gbeta3 variants were not associated with lithium outcome, even when possible stratification effects such as sex, polarity, age at onset, duration of lithium treatment, and previous episodes were included in the model. The pathways influenced by those variants are not therefore involved with long-term lithium outcome in our sample.

Abstract
The aim of this study was to investigate the possible association between the functional polymorphism in the upstream regulatory region of the serotonin transporter gene (5-HTTLPR) and the prophylactic efficacy of lithium in mood disorders. Two hundred and one subjects affected by bipolar (n = 167) and major depressive (n = 34) disorder were followed prospectively for an average of 58.2 months and were typed for their 5-HTTLPR variant using polymerase chain reaction techniques. 5-HTTLPR variants were associated with lithium outcome (F = 5.35; df = 2,198; P = 0.005). Subjects with the s/s variant showed a worse response compared to both l/s and l/l variants. Consideration of possible stratification effects such as sex, polarity, age at onset, duration of lithium treatment and previous episodes did not influence the observed association. 5-HTTLPR variants may be a possible influencing factor for the prophylactic efficacy of lithium in mood disorders.

Abstract
BACKGROUND It has been recently reported that the short variant of the serotonin transporter (5-HTT) gene-linked functional polymorphic region (5-HTTLPR) influences the antidepressant response to certain selective serotonin reuptake inhibitors. The aim of the present study was to test this finding in a sample of major and bipolar depressives, with or without psychotic features. METHODS One hundred fifty-five inpatients were treated with fluvoxamine 300 mg and either placebo or pindolol in a double-blind design for 6 weeks. The severity of depressive symptoms was weekly assessed with the Hamilton Rating Scale for Depression. Allelic variation of 5-HTTLPR in each subject was determined using a polymerase chain reaction-based technique. RESULTS 5-HTTLPR short variant was associated with a poor response to fluvoxamine treatment, independently from the recorded clinical variables. More specifically, the diagnosis, the presence of psychotic features, and the severity of depressive symptomatology did not influence this association. Conversely, pindolol augmentation may ameliorate the rate of response in 5-HTTLPR short variant subjects, thus reducing the difference in the response rate among the genotype variants. CONCLUSIONS If confirmed, these results may improve patient care by helping the clinician to individualize treatment according to the patient's genetic 5-HTTLPR pattern.

Abstract
The aim of this study is to investigate possible clinical predictors of the long-term outcome of mood disorders. We undertook a retrospective assessment of 426 inpatients affected by major depressive disorder (n=182) and bipolar disorder (n=244), with at least two episodes of illness alternating with complete recovery; subjects were affected for an average of 14.43+/-11.34 years and presented an average of 4.4+/-2.1 episodes. Random regression model analysis (http://www.uic.eu/hedeker/mix.html) was used to investigate the longitudinal time course of the illness. A progressive cycle shortening was observed, whereby the more episodes a subject experienced, the shorter the interval was between episodes, up to a plateau frequency of one episode/year on average. Bipolar diagnosis was the strongest predictive factor toward high frequency of episodes; a manic onset among bipolars was associated with an even worse outcome. Gender, education level, family history, duration of the first interval, severity of the first episode, lifetime mean severity and lifetime mean treatment level were not associated with outcome in terms of episode frequency. Our results suggest that recurrent affective disorders recruited in a clinical setting have a marked deteriorating mean time course.
