Abstract Background Type-1 diabetes mellitus (DM) is a lifelong serious condition which often renders the application of standard treatment options for patients' comorbid conditions, such as bipolar disorder I, risky – especially for acute manic episodes. We present such a case whereby the application of standard anti-manic treatments would have jeopardized a patient whose physical condition was already compromised by DM. Methods We report the case of a 55-year-old female with a history of type-1 DM since the age of 11, and severe ocular and renal vascular complications thereof. While on the waiting list for pancreatic islet cell transplantation, she developed a manic episode that proved recalcitrant to a treatment with gabapentin, lorazepam and quetiapine. Moreover, her mental state affected adversely her already compromised glycemic control, requiring her psychiatric hospitalization. Her psychotropic medication was almost discontinued and replaced by oxcarbazepine (OXC) up to 1800 mg/day for 10 days. Results The patient's mental state improved steadily and on discharge, 3 weeks later, she showed an impressive improvement rate of over 70% on the YMRS. Moreover, she remains normothymic 6 months after discharge, with OXC at 1200 mg/day. Conclusion Standard prescribing guidelines for acute mania recommend a combination of an antipsychotic with lithium or, alternatively, a combination of an antipsychotic with valproate or carbamazepine. However, in our case, administration of lithium was at least relatively contra-indicated because of patient's already compromised renal function. Furthermore, antipsychotics increase glucose levels and thus were also relatively contra-indicated. Moreover, the imminent post-transpantation immunosupressant treatment with immuno-modulating medicines also contra-indicated both valproate and carbamazepine. Despite the severe methodological limitations of case reports in general, the present one suggests that OXC as monotherapy might be both safe and efficacious in the treatment of acute mania in patients with early-onset type-1 DM, whose already compromised physical condition constitutes an absolute or relative contra-indication for the administration of standard treatments, though there are no, as yet, randomized clinical trials attesting to its efficacy unambiguously.

Background: Increased arterial stiffness (AS) might be one significant acute mediator of the well-attested association between female depression and cardiovascular disease., Methods: We tested this hypothesis in an inpatient sample of 20 drug-free women undergoing a new clinically severe major depressive episode of recent onset with an adequately matched mentally healthy control group. Patients' clinical (Hamilton Depression Rating Scale) and vascular (Pulse-Wave-Velocity, PWV) assessments were performed both before the initiation and after the completion of their six-week antidepressant treatment., Results: Although initially patients exhibited significantly higher PWV values than controls, this was decreased and reached comparable levels to controls after treatment completion. Moreover, full-responders exhibited significantly greater vascular improvement than their partial-responders counterparts and the magnitude of their amelioration was strongly associated with the magnitude of their clinical improvement., Limitations: Our sample-size was small and patients' follow-up short., Conclusions: Our findings provide support to the hypothesis that current severe major depressive episode in women leads acutely to aggravation of arterial stiffness, reversible however upon timely and effective antidepressant treatment., (Copyright 2009 Elsevier B.V.

Despite the recent progress in the pharmacological treatment of obsessive-compulsive disorder (OCD)--especially with high doses of serotonin reuptake inhibitors, alone or in combination with low doses of antipsychotics--a non-negligible proportion of patients remains refractory to it. For these patients augmentation tactics with drugs from other chemical classes, including antiepileptic drugs, seems advisable. We report on the case of a female inpatient with OCD, whereby the adjunction of tiagabine, a selective GABA reuptake inhibitor at 15 mg/day, to a fluvoxamine (400 mg/day)-risperidone (1 mg/day) combination led to the patient's marked improvement as reflected in the reduction by almost 47% of her score on the Yale-Brown Obsessive Compulsive Scale. With respect to tiagabine's specifically anti-OCD mechanism of action, we note that enhanced inhibitory GABAergic neurotransmission slows down excitatory glutamatergic transmission in the cortico-striato-thalamic system, which presumably constitutes the core pathophysiological mechanism of OCD symptoms.

Objective: Tolerance, dependence, and adverse effects on cognitive functions are well-known consequences of long-term use of benzodiazepines (BDZ), especially at high doses, raising thorny therapeutic problems in their discontinuation. One promising pharmacological agent in BDZ discontinuation might be the newer anti-epileptic pregabalin, already successfully tested in the treatment of anxiety disorders., Methods: We report on a sample of 15 patients with long-term, mostly high-dose dependence from BDZ, treated with pregabalin in an open-label study at doses 225-900 mg., Results: All patients discontinued successfully BDZ in 3-14 weeks, moreover with a significant reduction of their previous anxiety levels under BDZ. In addition, patients showed also a significant amelioration in their cognitive functioning. Pregabalin's side-effects were mild and transient, lasting only during the first 2 weeks of treatment., Conclusion: Although preliminary, our findings suggest that pregabalin may be one new promising agent in the treatment of BDZ dependence., ((c) 2008 John Wiley & Sons, Ltd.)

Tolerance, dependence, and adverse effects on cognitive functions are well known consequences of long-term use of benzodiazepines (BDZ), especially at high doses; this raises thorny therapeutic problems in their discontinuation. One promising pharmacological agent in BDZ discontinuation might be the newer antiepileptic, pregabalin (PGB), which has already successfully been tested in the treatment of anxiety disorders. We report on a series of four women with long-term, high-dose dependence on BDZ, who were treated with PGB at doses of 225-600 mg. All four patients discontinued BDZ successfully in 3-7 weeks. Moreover, they had an impressive reduction of their previous anxiety levels under BDZ. In addition, the patients showed a clinically significant amelioration in their cognitive functioning. The side effects of PGB were mild and transient, persisting only during the first 2 weeks of treatment. Although our findings are preliminary, they suggest that PGB might be one of the most promising of the newer agents in the treatment of BDZ dependence.
