Lamotrigine in the treatment of psychotic depression associated with hereditary coproporphyria -- case report and a brief review of the literature.

OBJECTIVE: We report a successful treatment with lamotrigine of a patient with hereditary coproporphyria presenting with affective and psychotic symptoms. CASE REPORT: M.F., a 38-year-old, single woman was admitted to an acute psychiatric ward because of suddenly emerging psychosis. Ms F's hereditary coproporphyria was diagnosed 9 years before the current admission. While on treatment with olanzapine (20mg/day) the psychotic symptoms have gradually disappeared. In view of her significant mood fluctuations predominantly with depressed phases, lamotrigine was started and titrated up to 125 mg/day. Ms F's mood gradually became euthymic, suicidal ideations and anxiety disappeared. At 5-month follow-up, while still on lamotrigine, her porphyria was asymptomatic. CONCLUSION: To the best of our knowledge, this is the first report about the safe administration of lamotrigine in hereditary coproporphyria. Lamotrigine did not trigger an acute porphyric attack as confirmed by clinical and laboratory findings.

[Clinical characteristics of cannabis-induced schizophrenia spectrum disorder]. / Kannabiszhasználat mellett kialakuló szkizofréniaspektrum-zavar klinikai jellegzetességeinek vizsgálata.

Marijuana (cannabis) is the most commonly abused drug by adolescents and young adults and also by people with schizophrenia or other psychotic disorders. An increasing number of studies suggest that regular cannabis users can show psychotic episodes similar to schizophrenic disorders but it still unclear if cannabis induced psychotic disorder is a distinct entity requiring special therapy or regular cannabis use consequently leads to schizophrenia. Therefore, we retrospectively compared psychotic patients with and without cannabis use by clinical profile. Clinical data of 85 patients with schizophrenia spectrum disorder were analyzed retrospectively. Cannabis use was not reported by 43 persons (Cnbs0 subgroup) and 42 patients used regularly cannabis during at least 1 year (Cnbs1 subgroup). Clinical data were collected from electronic medical documentation of patients concerning anamnesis, family history, socio-demographic condition, symptoms and psychiatric state, acute and long-term therapies. Men were over-represented in the cannabis abuser group while mean age was lower among them compared to the Cnbs0 subgroup. Prevalence of suicidal attempts was increased in men without cannabis use. Patients without cannabis use spent more time in hospital and smoking was more frequent among them. Positive and negative symptoms and family history did not differ significantly between the two subgroups. Dosage, intensity and length of pharmacotherapy was different between the two subgroups. These results revealed that certain clinical aspects were different in case of cannabis-related schizophrenia spectrum disorder compared to schizophrenia.

Psychopharmacological comparison of schizophrenia spectrum disorder with and without cannabis dependency.

BACKGROUND: Although incidence of schizophrenia is higher among cannabis users and marijuana is the most common abused drug by adolescents, etiological linkage between schizophrenia and cannabis use is still not clarified. Clinical experiences suggest that regular cannabis user can show similar psychotic episode to schizophrenic disorders but it is still unclear if chronic cannabis use with schizophreniform disorder is a distinct entity requiring special therapy or it can be treated as classical schizophrenia. There are no data available on the comparison of pharmacotherapy between schizophreniform patients with and without cannabis use. METHODS: Clinical data of 85 patients with schizophrenia spectrum disorder were analyzed retrospectively. Cannabis use was not reported by 43 persons (Cnbs0 subgroup) and 42 patients used regularly cannabis during at least 1 year (Cnbs1 subgroup). Comparison of anamnesis, family history, social-demographic condition, positive and negative symptoms, acute and long-term therapies recorded by clinical interviews was performed with chi square tests, logistic binary regression and t-tests using SPSS 13.0 for Windows software. RESULTS: Men were over-represented in cannabis dependent group while mean age was lower among them compared to Cnbs0 subgroup. Prevalence of suicidal attempt was increased in men without cannabis use (OR = 5.25, p = 0.016). Patients without cannabis use spent more time in hospital (p = 0.026) and smoking was more frequent among them (OR = 1.36, p = 0.047). The chance to get olanzapine for acute therapy and aripiprazol for long term therapy was more than two fold in Cnbs1 subgroup (OR = 2.66, OR = 3.67, respectively). However, aripiprazol was used for acute therapy with significantly lower risk in Cnbs1 subgroup (OR = 0.47, p = 0.023). Olanzapine was administered for long term therapy in a higher dose to Cnbs0 patients (p = 0.040). Also higher dose of risperidon LAI was used in women without cannabis dependency compared to women of Cnbs1 subgroup (p=0.020). Positive and negative symptoms and family history did not differ significantly between the two subgroups. CONCLUSION: Although symptom profile was similar, hospitalization time, suicidal anamnesis, smoking habit and also dosage, intensity and lasting of therapy were different between the two subgroups. Further prospective studies are required for the investigation of the clinical and molecular background of this discrepancy in order to determine a relevant protocol of prevention and treatment of the chronic cannabis use related psychotic disorder.

[SCHIZOBANK - The Hungarian national schizophrenia biobank and its role in schizophrenia research and in personalized medicine]. / Magyar szkizofrénia-biobank a szkizofréniakutatás és a személyre szabott orvoslás szolgálatában.

Delineating the pathogenesis of multifactorial diseases is a major challenge of the postgenomial era. Genetic factors are known to play an important role in the pathogenesis of certain psychiatric disorders as well as in the development of adverse reactions to psychoactive drugs. Containing large numbers of samples and linking them clinical data, biobanks are gaining importance in the studies of chronic multifactorial diseases. Several biobanks are under establishment in Hungary. The first initiative to collect samples in neurological and psychiatric disorders was the NEPSYBANK coordinated by the Hungarian Society of Clinical Neurogenetics. The national biobank network is currently established by the NEKIFUT project of the National Office of Research and Technology. In this article we describe the structure, logistics and informatical background of the national schizophrenia biobank (SCHIZOBANK). The initiative of the SCHIZOBANK originates from a consortium in which academy and health industry partners are collecting biological materials and data in five major psychiatric center under the coordination of the Medical and Health Science Center of the University of Debrecen. We review other international schizophrenia biobanks as well. Major strength of the SCHIZOBANK is the collection of very detailed phenotypic data and of RNA and plasma both in psychotic and non-psychotic state of the patient which permits longitudinal follow-up and the study of both static and dynamically changing transcriptomic, proteomic and metabolomic markers. The collection of the SCHIZOBANK is available not only to consortial partners but to other national and international research groups as well.

Early experience with Suboxone maintenance therapy in Hungary.

BACKGROUND: Suboxone (Buprenorphine/naloxone) is a novel drug used in opiate substitution therapy. In Hungary, it was introduced in November 2007. Suboxone is a product for sublingual administration containing the partial mu-receptor agonist buprenorphine and antagonist naloxone in a 4:1 ratio. OBJECTIVE: Objectives of our study were to monitor and evaluate the effects of Suboxone treatment. METHOD: 6 outpatient centers participated in the study, 3 from Budapest and 3 from smaller cities in Hungary. At these centers, all patients entering Suboxone maintenance therapy between November 2007 and March 2008, altogether 80 persons (55 males, 35 females, mean age = 30.2 years, SD=5.48) were included in the study sample. During the 6-month period of treatment, data were collected 4 times; when entering treatment, 1 month, 3 months, and 6 months after entering treatment. Applied measures were the Addiction Severity Index, SCID-I, SCID-II, Hamilton Depression Scale, Hamilton Anxiety Scale, STAI-S State Anxiety Inventory, Beck Depression Inventory, Heroin Craving Questionnaire, WHO Well-being Inventory, Perceived Stress Scale, ADHD retrospective questionnaire, TCI short version, and Ways of Coping questionnaire. RESULTS: Nearly fourth of the altogether 80 heroin dependent patients (18 persons, 22.5%) dropped out of treatment during the first month (the majority, 12 persons [15%] during the first week) or chose methadone substitution instead. Following this period however, dropout rate decreased and the six-month treatment period was completed by 32 patients (40%). During the first month of treatment significant positive changes were experienced in all studied psychological and behavioral dimensions that proved to be stabile throughout the studied period. CONCLUSIONS: According to the early experience with Suboxone treatment, it is a well tolerable and successfully applicable drug in the substitution therapy of opiate addicts. A critical phase seems to be the first one or two weeks of treatment. Dropout rate is high during this early period, while after a successful conversion clients presumably remain in therapy for a long period. At the beginning of administration special emphasis must be put on informing patients, especially concerning withdrawal symptoms that might be present during the first week, which highly contributes to better retention in treatment.
