TREATMENT PATTERNS OF SCHIZOPHRENIA BASED ON THE DATA FROM SEVEN CENTRAL AND EASTERN EUROPEAN COUNTRIES

Objective: The aim is to analyze how schizophrenia is pharmacologically treated in seven CEE countries: Croatia, Estonia, Hungary, Poland, Serbia, Slovakia and Slovenia. Methods: Psychiatrists from selected centers in each of participating countries were asked to complete a pre-defined questionnaire on their current clinical practice. Information on protocols and resource utilization in schizophrenia treatment was included and derived from randomly selected patient medical records. Expert opinions on country-wide treatment patterns were additionally sought. This sub-analysis focuses on pharmacological treatment patterns in the last six months and over the course of the disease. Results: 961 patients’ data show that during last six months the most commonly prescribed medications were oral atypical antipsychotics: olanzapine (n=268), clozapine (n=234) and risperidone (n=160). The most frequently prescribed atypical antipsychotics over course of disease were: risperidone (54.5%), olanzapine (52.4%) and clozapine (35.1%), along with haloperidol (39.3%). Experts reported risperidone (four countries) and olanzapine (three countries) as first-line treatment, with the same two medications prescribed as second-line treatment. Clozapine was the most reported medication for refractory patients. Approximately 22% of patients received polypharmacy with antipsychotics in at least one period over the disease course. Mean time since diagnosis was 13.1 years and on average 4.8 treatment courses received during that period. Anxiolytics (70%), antidepressants (42%), moodstabilizers (27%) were also prescribed, with diazepam (35.4%), sertraline (10.5%), valproic acid (17.5%) the most commonly reported, respectively, in each group. The most frequently reported treatment change was switch from one oral atypical antipsychotic to another (51%). Conclusion: Oral atypical antipsychotics, mostly older drugs (risperidone, olanzapine, clozapine), were most commonly prescribed for schizophrenia treatment in participating countries. Given that results are from the first large-scale analysis of RWD, we believe these findings can be a benchmark for future real-world studies, which could contribute to the optimization of treatment for this debilitating disease

SCHIZOPHRENIA CAUSES SIGNIFICANT BURDEN TO PATIENTS’ AND CAREGIVERS’ LIVES

Background: Schizophrenia is a serious public health problem and is ranked among the most disabling diseases in the world. The sub-study presented here was part of a larger project to characterize the burden of schizophrenia on healthcare systems and on individuals living with the disease in Central and Eastern Europe (CEE). Aims: This sub-study aimed to assess and analyze the impact of schizophrenia on many aspects of the lives of patients and caregivers. Methods: Psychiatrists from selected centers in seven Central and Eastern European countries were asked to complete a questionnaire in order to collect information about the disease history, characteristics, treatment protocols and resources used for each randomly selected patient. All data were statistically analyzed and compared between countries. Results: Data from 961 patients with schizophrenia (mean age 40.7 years, 45.1% female) were included in the analysis. The mean number of days spent in hospital per patient per year across all seven countries was 25.3 days. Hospitalization occurred on average once per year, with psychiatrist visits 9.4 times per year. Of the patients in the study, 61% were single, 12% divorced and 22% married or cohabiting. Almost 84% were living with relatives or a partner; only 17% lived alone and, on average, 25% of patients received support from social workers. Relatives provided care for approximately 60% of patients and 4% of them had to stop working in order to do so. Twenty-nine percent of the patients were unemployed, and 56% received a disability pension or were retired, with only 19% in full-time employment or education. Conclusion: Schizophrenia has a significant effect on the lives of patients and caregivers and impacts their social integration

Epidemiology and Treatment Guidelines of Negative Symptoms in Schizo-phrenia in Central and Eastern Europe: A Literature Review

AIM: To gather and review data describing the epidemiology of schizophrenia and clinical guidelines for schizophrenia therapy in seven Central and Eastern European countries, with a focus on negative symptoms. Methods : A literature search was conducted which included publications from 1995 to 2012 that were indexed in key databases. Results : Reports of mean annual incidence of schizophrenia varied greatly, from 0.04 to 0.58 per 1,000 population. Lifetime prevalence varied from 0.4% to 1.4%. One study reported that at least one negative symptom was present in 57.6% of patients with schizophrenia and in 50-90% of individuals experiencing their first episode of schizophrenia. Primary negative symptoms were observed in 10-30% of patients. Mortality in patients with schizophrenia was greater than in the general population, with a standardized mortality ratio of 2.58-4.30. Reasons for higher risk of mortality in the schizophrenia population included increased suicide risk, effect of schizophrenia on lifestyle and environment, and presence of comorbidities. Clinical guidelines overall supported the use of second-generation antipsychotics in managing negative symptoms of schizophrenia, although improved therapeutic approaches are needed. Conclusion : Schizophrenia is one of the most common mental illnesses and poses a considerable burden on patients and healthcare resources alike. Negative symptoms are present in many patients and there is an unmet need to improve treatment offerings for negative symptoms beyond the use of second-generation antipsychotics and overall patient outcomes

Metabolic Effects of Paliperidone Extended Release Versus Oral Olanzapine in Patients With Schizophrenia A Prospective, Randomized, Controlled Trial

Metabolic effects are generally more pronounced with second-generation than first-generation antipsychotics. This study was designed to compare long-term metabolic effects and efficacy of paliperidone extended release (ER) with those of oral olanzapine in patients with schizophrenia. In this 6-month, multicenter, prospective, randomized, controlled, open-label, parallel-group study, adults with schizophrenia were treated with paliperidone ER (6-9 mg/d; n = 239) or oral olanzapine (10-15 mg/d; n = 220). The primary outcome was mean change in the ratio of serum triglyceride level to high-density lipoprotein level (TG/HDL), a marker of insulin resistance. Other outcome measures included the Positive and Negative Syndrome Scale scores, measures of lipid and glucose metabolism, and body weight. Significant improvements in psychotic symptoms were observed with both treatments (P < 0.0001). The TG/HDL ratio was significantly higher at end point versus baseline with olanzapine compared with that of paliperidone ER. Mean end point change in TG/HDL ratio was 0.097 +/- 2.72 for olanzapine (P < 0.0001, reflecting worsening), with no significant change for paliperidone ER (-0.17 +/- 2.51). Newly diagnosed impairment in TG and metabolic syndrome was more common with olanzapine (P < 0.05). Insulin resistance, as measured by the homeostasis model assessment of insulin resistance, worsened significantly with olanzapine (P = 0.0003), but not with paliperidone ER. Glucose sensitivity for insulin worsened significantly with olanzapine (P < 0.03), with no significant changes for paliperidone ER. End point increase in body weight was significantly higher with olanzapine than paliperidone ER (3.8 vs 1.2 kg; P = 0.0013). In summary, both paliperidone ER and olanzapine effectively treated schizophrenia; however, undesirable metabolic effects were significantly greater with olanzapine

Paliperidone palmitate versus oral antipsychotics in recently diagnosed schizophrenia

Objective: Relapse and acute exacerbation are common in schizophrenia and may impact treatment response and outcome. Evidence is conflicting in respect to superiority of long-acting injectable antipsychotic therapies versus oral antipsychotics in relapse prevention. This randomized controlled study assessed the efficacy of paliperidone palmitate versus oral antipsychotics for relapse prevention
