Oxcarbazepine as monotherapy of acute mania in insufficiently controlled type-1 diabetes mellitus: a case-report

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusion</p> <p>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.</p

Remission of migraine attacks in a patient with depression who is taking pregabalin

Antiepileptic drugs (AED) are increasingly used in the treatment of migraine. Pregabalin (PGB) is an AED that has been used in the treatment of partial seizures, of various types of pain, and of certain anxiety disorders, but to the best of our knowledge, there has been no report on the use of PGB in the treatment of migraine. We report the case of a 60-year-old female inpatient with depression, long experiencing migraine, whose migraine symptoms improved markedly after receiving PGB in combination with escitalopram administered for her depression. The PGB mechanism of action in conjunction with its structural similarity with gabapentin, already successfully tested in the treatment of migraine, provide additional supportive evidence, theoretical and clinical, respectively, for PGB potential to alleviate migraine symptoms. However, only carefully randomized, controlled studies, or at the very least, open-label series of large patient samples treated in a similar fashion could establish the efficacy of PGB in migraine treatment

Pregabalin in the discontinuation of long-term benzodiazepine use: a case-series

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

Tiagabine augmentation to fluvoxamine-risperidone combination in the treatment of obsessive-compulsive disorder

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

The safety of the electroconvulsive therapy-aripiprazole combination: Four case reports

In clinical practice, a proportion of patients with psychotic or mood disorders are treated with electroconvulsive therapy (ECT) while receiving concomitantly antipsychotic and/or other psychotropic agents. Aripiprazole is a second-generation antipsychotic that seems to have a favorable side-effect profile. However, to the best of our knowledge, there are, as yet, no available reports oil the safety of ECT-aripiprazole combination. We report the cases of 4 female inpatients-3 suffering from major depression and I from schizophrenia-who underwent ECT-1 of them twice-while receiving aripiprazole (10-15 mg/d), as part of their regimen. I it all cases, the combination was well tolerated and only minimal side effects were reported

Pregabalin in the discontinuation of long-term benzodiazepines&apos; use

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. Copyright (c) 2008 John Wiley &amp; Sons, Ltd

Levetiracetam in the treatment of antipsychotics-resistant Tourette syndrome

Levetiracetam, an anti-epileptic agent that enhances GABAergic neurotransmission, is one of the newest alternative treatments of Tourette syndrome (TS). We present the case of a 23-year-old female patient suffering from TS since the age of 7, who exhibited poor response to a variety of agents (haloperidol, pimozide, clonidine and various adjunctive agents) and had four hospitalizations during the previous 2 years due to the deterioration of her clinical state. On her last admission, in addition to clonidine 600 g/day (already part of her regimen for the previous 4 years), levetiracetam was prescribed, up to 2000 mg/day, progressively titrated over a 3-week period. The patient presented a significant improvement on her TS symptomatology (the score on the Yale Global Tic Severity Scale dropped from 70 at admission, to 25 five weeks later, at discharge), which was preserved during the subsequent 4 months, without any serious side-effect
