Randomized trial comparing caregiver-only family-focused treatment to standard health education on the 6-month outcome of bipolar disorder.

OBJECTIVES: Caregivers of people with bipolar disorder often have depression and health problems. This study aimed to evaluate the sustained effects of a 12-15 week psychoeducational intervention on the health and mental health of caregivers of persons with bipolar disorder. We also evaluated the effects of the intervention on patients' mood symptoms over 6 months post-treatment. METHODS: Caregivers of 46 persons with bipolar disorder were randomized to 12-15 weeks of a caregiver-only adaptation of family-focused treatment (FFT), in which caregivers were instructed on self-care strategies and ways to assist the patient in managing the illness, or to 8-12 sessions of standard health education. Independent evaluators assessed caregivers' depression and physical health and patients' mood symptoms before treatment, immediately after the treatment, and at 6 months post-treatment. RESULTS: Randomization to FFT was associated with greater decreases in depression for both caregivers and patients over a 6-month follow-up period post-treatment. Reductions in patients' depression scores over 6 months post-treatment were mediated by reductions in caregivers' depression scores (z = -2.74, P < .01). CONCLUSIONS: Interventions that are effective in reducing mood symptoms and improving health behavior in caregivers may have important health and mental health benefits for patients with bipolar disorder. Specifically, a treatment focused on caregiver education about bipolar disorder and the need for the caregiver to attend to his/her own health and mental health can benefit patients, even without their direct participation.

Family-focused treatment for caregivers of patients with bipolar disorder.

OBJECTIVES: Family members of patients with bipolar disorder experience high rates of subjective and objective burden which place them at risk for adverse physical health and mental health outcomes. We present preliminary efficacy data from a novel variation of Family Focused Treatment [Miklowitz DJ. Bipolar Disorder: A Family-Focused Treatment Approach (2(nd) ed.). New York: The Guilford Press, 2008] that aimed to reduce symptoms of bipolar disorder by working with caregivers to enhance illness management skills and self-care. METHODS: The primary family caregivers of 46 patients with bipolar I (n = 40) or II (n = 6) disorder, diagnosed by the Structured Clinical Interview for DSM-IV Axis I Disorders, were assigned randomly to receive either: (i) a 12-15-session family-focused, cognitive-behavioral intervention designed to provide the caregiver with skills for managing the relative's illness, attaining self-care goals, and reducing strain, depression, and health risk behavior [Family-Focused Treatment-Health Promoting Intervention (FFT-HPI)]; or (ii) an 8- to 12-session health education (HE) intervention delivered via videotapes. We assessed patients pre- and post-treatment on levels of depression and mania and caregivers on levels of burden, health behavior, and coping. RESULTS: Randomization to FFT-HPI was associated with significant decreases in caregiver depressive symptoms and health risk behavior. Greater reductions in depressive symptoms among patients were also observed in the FFT-HPI group. Reduction in patients' depression was partially mediated by reductions in caregivers' depression levels. Decreases in caregivers' depression were partially mediated by reductions in caregivers' levels of avoidance coping. CONCLUSIONS: Families coping with bipolar disorder may benefit from family interventions as a result of changes in the caregivers' ability to manage stress and regulate their moods, even when the patient is not available for treatment.

A randomized controlled clinical trial of psychoanalytic psychotherapy for panic disorder.

OBJECTIVE: The purpose of this study was to determine the efficacy of panic-focused psychodynamic psychotherapy relative to applied relaxation training, a credible psychotherapy comparison condition. Despite the widespread clinical use of psychodynamic psychotherapies, randomized controlled clinical trials evaluating such psychotherapies for axis I disorders have lagged. To the authors' knowledge, this is the first efficacy randomized controlled clinical trial of panic-focused psychodynamic psychotherapy, a manualized psychoanalytical psychotherapy for patients with DSM-IV panic disorder. METHOD: This was a randomized controlled clinical trial of subjects with primary DSM-IV panic disorder. Participants were recruited over 5 years in the New York City metropolitan area. Subjects were 49 adults ages 18-55 with primary DSM-IV panic disorder. All subjects received assigned treatment, panic-focused psychodynamic psychotherapy or applied relaxation training in twice-weekly sessions for 12 weeks. The Panic Disorder Severity Scale, rated by blinded independent evaluators, was the primary outcome measure. RESULTS: Subjects in panic-focused psychodynamic psychotherapy had significantly greater reduction in severity of panic symptoms. Furthermore, those receiving panic-focused psychodynamic psychotherapy were significantly more likely to respond at treatment termination (73% versus 39%), using the Multicenter Panic Disorder Study response criteria. The secondary outcome, change in psychosocial functioning, mirrored these results. CONCLUSIONS: Despite the small cohort size of this trial, it has demonstrated preliminary efficacy of panic-focused psychodynamic psychotherapy for panic disorder.

Impact of point-of-care B-type natriuretic peptide (BNP) measurement on medical decision-making for older emergency department patients with dyspnea.

Measurement of B-type natriuretic peptide (BNP) has been shown to aid in the Emergency Department (ED) diagnosis of heart failure. We sought to determine how point-of-care BNP measurement influences real-world medical decision-making. Using a commercially available, point-of-care assay, BNP levels were measured in a convenience sample of ED patients over the age of 55 years who complained of dyspnea. Blinded to BNP results, emergency physicians were asked to formulate a differential diagnosis and management plan for each patient. Immediately thereafter, BNP results were disclosed and the physicians were asked what (if any) decisions they would change. With physicians blinded to BNP results, 24 of 88 patients (27%) were given a primary diagnosis of heart failure, and 18 patients (20%) were given a secondary or alternative diagnosis of heart failure. For the former group, disclosure of BNP results resulted in no changes in diagnosis or management. For the latter group, disclosure of BNP results caused heart failure to become the primary diagnosis in 4 patients (22%), and led to five changes in medical management. For the 46 patients initially given neither a primary nor secondary diagnosis of heart failure, disclosure of BNP results caused heart failure to become the primary diagnosis in one patient (2%) and a secondary diagnosis in 4 patients (9%), and led to five changes in medical management. Thus, for ED patients with a primary clinical diagnosis of heart failure, BNP testing had no impact on medical decision-making. However, for other patients with dyspnea, elevated BNP levels did influence medical decision-making, particularly when heart failure was in the differential diagnosis.

Panic disorder and depression: a psychodynamic exploration of comorbidity.

Eight of twenty-one patients presenting for treatment in an open trial of brief psychodynamic psychotherapy for panic disorder also carried the diagnosis of major depression. For the patients who completed the study, depression remitted as well as panic disorder. The authors highlight psychodynamic factors that they hypothesize may contribute to the significant overlap between panic disorder and depression, and describe three videotaped cases to illustrate these points.

Bartter syndrome complicated by immune complex nephropathy. Case report and literature review.

The unusual coincidence of Bartter syndrome and C1q nephropathy is described and the literature reviewed. An African-American girl presented at 4 years of age with acute hyponatremic dehydration and failure to thrive. Persistent hypokalemic alkalosis and secondary hyperaldosteronism were found. The case was atypical for Bartter syndrome in that proteinuria (0.19 g/day) was present. Renal biopsy showed juxtaglomerular hyperplasia and C1q nephropathy. Molecular analysis showed deletion of the renal chloride channel gene (CLCNKB) typical of autosomal recessive childhood Bartter syndrome. Chronic sodium and potassium chloride replacement therapy together with indomethacin normalized her metabolic status, and she experienced catch-up growth. Proteinuria persisted, however. This is the first documentation of C1q nephropathy, in mild form, complicating autosomal recessive Bartter syndrome. This case shows the importance of the renal biopsy and of molecular analysis in delineating the cause of atypical nephropathy associated with Bartter syndrome. These findings add to the evidence of a possible association between the congenital syndrome and acquired immune complex nephropathy.
