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
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' 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.

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
Reversal of increased arterial stiffness in severely depressed women after 6-week antidepressant treatment
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. (C) 2009 Elsevier B.V. All rights reserved
