Abstract
IntroductionThere is substantial evidence that even minor perturbation of thyroid function plays a significant role in clinical course and treatment outcome in depressive disorder; however the same is not yet clear in bipolar disorders.Aims and objectivesTo study the relationship between pretreatment thyroid profile and response to treatment with lithium along with other predictors of response to treatment with lithium in cases of bipolar mood disorder.MethodsThis study was conducted in the indoor facilities of a regional Institute of Mental Health, Tezpur, India in the year of 2012. Forty-five consecutive indoor patients diagnosed with bipolar mood disorder using DSM-IV-TR criteria were selected. On day 1, blood was collected for thyroid profile and BPRS 24 item scale version 4.0 was applied. They were started on lithium monotherapy and only lorazepam was used on S.O.S basis. On day 30, the BPRS was applied again to check the response to treatment, statistical analysis was done using SPSS version 16.ResultsThe mean percentage fall of the BPRS score was 40%, with the maximum fall in the subscale of grandiosity and minimum for depression. Age, illness duration, substance use, family history second or later episodes were negatively correlated with treatment response. Pretreatment T4 level was positively correlated, while pretreatment TSH level was negatively correlated with the treatment response.ConclusionLithium monotherapy proved to be a good agent for first episode of bipolar Mood disorder patients with manic symptoms and pretreatment T4 and TSH level were predictors of treatment response.Disclosure of interestThe authors have not supplied their declaration of competing interest.
