    Background Lithium is regarded as a first-line treatment for bipolar disorder (BD), but partial response and non-response commonly occurs. There exists a need to identify lithium non-responders prior to initiating treatment. The Pharmacogenomics of Bipolar Disorder (PGBD) Study was designed to identify predictors of lithium response. Methods The PGBD Study was an eleven site prospective trial of lithium treatment in bipolar I disorder. Subjects were stabilized on lithium monotherapy over 4 months and gradually discontinued from all other psychotropic medications. After ensuring a sustained clinical remission (defined by a score of ≤3 on the CGI for 4 weeks) had been achieved, subjects were followed for up to 2 years to monitor clinical response. Cox proportional hazard models were used to examine the relationship between clinical measures and time until failure to remit or relapse. Results A total of 345 individuals were enrolled into the study and included in the analysis. Of these, 101 subjects failed to remit or relapsed, 88 achieved remission and continued to study completion, and 156 were terminated from the study for other reasons. Significant clinical predictors of treatment failure (p < 0.05) included baseline anxiety symptoms, functional impairments, negative life events and lifetime clinical features such as a history of migraine, suicidal ideation/attempts, and mixed episodes, as well as a chronic course of illness. Conclusions In this PGBD Study of lithium response, several clinical features were found to be associated with failure to respond to lithium. Future validation is needed to confirm these clinical predictors of treatment failure and their use clinically to distinguish who will do well on lithium before starting pharmacotherapy.

    Diagnostic Interview for Genetic Studies: validity and reliability of the Croatian version
    (Wolters Kluwer, 2017-02) Kralj, Žana; Dedić, Milenka; Kovačević, Anđela; Malički, Mario; Dedić, Jelena; Pelivan, Marina; Vuković, Dubravka; Fisher, Carrie; Kember, Rachel L.; Nurnberger, John; Bućan, Maja; Britvić, Dolores; Psychiatry, School of Medicine
    OBJECTIVE: To test the validity and reliability of the Diagnostic Interview for Genetic Studies (DIGS) in patients with mental illness in Croatia. MATERIALS AND METHODS: Following translation, back-translation, and pilot testing, the Croatian version of DIGS (CRO-DIGS) was administered to a total of 150 inpatients and outpatients diagnosed at the Clinical Hospital in Split with bipolar and major depressive disorder (n=56), schizophrenia and schizoaffective disorder (n=62), and alcohol dependence or use disorders (n=32). Initial testing was performed independently by one interviewer and one observer blinded to the diagnosis, and a retest was performed after 8 weeks by a third examiner. RESULTS: The validity of CRO-DIGS was high (κ=0.916), with an excellent inter-rater (κ=0.824) reliability, especially for bipolar disorder (κ=0.956). Following an 8 week test-retest interval, the reliability for all diagnoses was found to be excellent (κ=0.843). CONCLUSION: Our study has shown excellent validity and reliability of the Croatian version of DIGS, making it a promising instrument to assess mental illness of patients. The development of a valid and reliable diagnostic tool such as the CRO-DIGS will considerably advance the scientific communities' ability to carry out genetic studies of psychiatric illness in the region.

    Focal adhesion is associated with lithium response in bipolar disorder: evidence from a network-based multi-omics analysis
    (Springer Nature, 2024) Niemsiri, Vipavee; Rosenthal, Sara Brin; Nievergelt, Caroline M.; Maihofer, Adam X.; Marchetto, Maria C.; Santos, Renata; Shekhtman, Tatyana; Alliey-Rodriguez, Ney; Anand, Amit; Balaraman, Yokesh; Berrettini, Wade H.; Bertram, Holli; Burdick, Katherine E.; Calabrese, Joseph R.; Calkin, Cynthia V.; Conroy, Carla; Coryell, William H.; DeModena, Anna; Eyler, Lisa T.; Feeder, Scott; Fisher, Carrie; Frazier, Nicole; Frye, Mark A.; Gao, Keming; Garnham, Julie; Gershon, Elliot S.; Goes, Fernando S.; Goto, Toyomi; Harrington, Gloria J.; Jakobsen, Petter; Kamali, Masoud; Kelly, Marisa; Leckband, Susan G.; Lohoff, Falk W.; McCarthy, Michael J.; McInnis, Melvin G.; Craig, David; Millett, Caitlin E.; Mondimore, Francis; Morken, Gunnar; Nurnberger, John I.; O'Donovan, Claire; Øedegaard, Ketil J.; Ryan, Kelly; Schinagle, Martha; Shilling, Paul D.; Slaney, Claire; Stapp, Emma K.; Stautland, Andrea; Tarwater, Bruce; Zandi, Peter P.; Alda, Martin; Fisch, Kathleen M.; Gage, Fred H.; Kelsoe, John R.; Psychiatry, School of Medicine
    Lithium (Li) is one of the most effective drugs for treating bipolar disorder (BD), however, there is presently no way to predict response to guide treatment. The aim of this study is to identify functional genes and pathways that distinguish BD Li responders (LR) from BD Li non-responders (NR). An initial Pharmacogenomics of Bipolar Disorder study (PGBD) GWAS of lithium response did not provide any significant results. As a result, we then employed network-based integrative analysis of transcriptomic and genomic data. In transcriptomic study of iPSC-derived neurons, 41 significantly differentially expressed (DE) genes were identified in LR vs NR regardless of lithium exposure. In the PGBD, post-GWAS gene prioritization using the GWA-boosting (GWAB) approach identified 1119 candidate genes. Following DE-derived network propagation, there was a highly significant overlap of genes between the top 500- and top 2000-proximal gene networks and the GWAB gene list (Phypergeometric = 1.28E-09 and 4.10E-18, respectively). Functional enrichment analyses of the top 500 proximal network genes identified focal adhesion and the extracellular matrix (ECM) as the most significant functions. Our findings suggest that the difference between LR and NR was a much greater effect than that of lithium. The direct impact of dysregulation of focal adhesion on axon guidance and neuronal circuits could underpin mechanisms of response to lithium, as well as underlying BD. It also highlights the power of integrative multi-omics analysis of transcriptomic and genomic profiling to gain molecular insights into lithium response in BD.

    A high-risk study of bipolar disorder. Childhood clinical phenotypes as precursors of major mood disorders
    (AMA, 2011-10) Nurnberger, John I. Jr.; McInnis, Melvin; Reich, Wendy; Kastelic, Elizabeth; Wilcox, Holly C.; Glowinski, Glowinski; Mitchell, Philip; Fisher, Carrie; Erpe, Mariano; Gershon, Elliot S.; Berrettini, Wade; Laite, Gina; Schweitzer, Robert; Rhoadarmer, Kelly; Coleman, Vegas V.; Cai, Xueya; Azzouz, Faouzi; Liu, Hai; Kamali, Masoud; Brucksch, Christine; Monahan, Patrick O.; Department of Medicine, IU School of Medicine
    CONTEXT: The childhood precursors of adult bipolar disorder (BP) are still a matter of controversy. OBJECTIVE: To report the lifetime prevalence and early clinical predictors of psychiatric disorders in offspring from families of probands with DSM-IV BP compared with offspring of control subjects. DESIGN: A longitudinal, prospective study of individuals at risk for BP and related disorders. We report initial (cross-sectional and retrospective) diagnostic and clinical characteristics following best-estimate procedures. SETTING: Assessment was performed at 4 university medical centers in the United States between June 1, 2006, and September 30, 2009. PARTICIPANTS: Offspring aged 12 to 21 years in families with a proband with BP (n = 141, designated as cases) and similarly aged offspring of control parents (n = 91). MAIN OUTCOME MEASURE: Lifetime DSM-IV diagnosis of a major affective disorder (BP type I; schizoaffective disorder, bipolar type; BP type II; or major depression). RESULTS: At a mean age of 17 years, cases showed a 23.4% lifetime prevalence of major affective disorders compared with 4.4% in controls (P = .002, adjusting for age, sex, ethnicity, and correlation between siblings). The prevalence of BP in cases was 8.5% vs 0% in controls (adjusted P = .007). No significant difference was seen in the prevalence of other affective, anxiety, disruptive behavior, or substance use disorders. Among case subjects manifesting major affective disorders (n = 33), there was an increased risk of anxiety and externalizing disorders compared with cases without mood disorder. In cases but not controls, a childhood diagnosis of an anxiety disorder (relative risk = 2.6; 95% CI, 1.1-6.3; P = .04) or an externalizing disorder (3.6; 1.4-9.0; P = .007) was predictive of later onset of major affective disorders. CONCLUSIONS: Childhood anxiety and externalizing diagnoses predict major affective illness in adolescent offspring in families with probands with BP.

    Traumatic Stress Interacts With Bipolar Disorder Genetic Risk to Increase Risk for Suicide Attempts
    (Elsevier, 2017-12) Wilcox, Holly C.; Fullerton, Janice M.; Glowinski, Anne L.; Benke, Kelly; Kamali, Masoud; Hulvershorn, Leslie A.; Stapp, Emma K.; Edenberg, Howard J.; Roberts, Gloria M. P.; Ghaziuddin, Neera; Fisher, Carrie; Brucksch, Christine; Frankland, Andrew; Toma, Claudio; Shaw, Alex D.; Kastelic, Elizabeth; Miller, Leslie; McInnis, Melvin G.; Mitchell, Philip B.; Nurnberger, John I., Jr.; Psychiatry, School of Medicine
    Objective Bipolar disorder (BD) is one of the most heritable psychiatric conditions and is associated with high suicide risk. To explore the reasons for this link, this study examined the interaction between traumatic stress and BD polygenic risk score in relation to suicidal ideation, suicide attempt, and nonsuicidal self-injury (NSSI) in adolescent and young adult offspring and relatives of persons with BD (BD-relatives) compared with adolescent and young adult offspring of individuals without psychiatric disorders (controls). Method Data were collected from 4 sites in the United States and 1 site in Australia from 2006 through 2012. Generalized estimating equation models were used to compare rates of ideation, attempts, and NSSI between BD-relatives (n = 307) and controls (n = 166) and to determine the contribution of demographic factors, traumatic stress exposure, lifetime mood or substance (alcohol/drug) use disorders, and BD polygenic risk score. Results After adjusting for demographic characteristics and mood and substance use disorders, BD-relatives were at increased risk for suicidal ideation and attempts but not for NSSI. Independent of BD-relative versus control status, demographic factors, or mood and substance use disorders, exposure to trauma within the past year (including bullying, sexual abuse, and domestic violence) was associated with suicide attempts (p = .014), and BD polygenic risk score was marginally associated with attempts (p = .061). Importantly, the interaction between BD polygenic risk score and traumatic event exposures was significantly associated with attempts, independent of demographics, relative versus control status, and mood and substance use disorders (p = .041). Conclusion BD-relatives are at increased risk for suicide attempts and ideation, especially if they are exposed to trauma and have evidence of increased genetic vulnerability.
