Quality of life in newly-debuted epilepsy. An empirical study

Investigation on the Influencing Factors Related to Quality of Life of Adult Epilepsy Patients in Wenzhou, China, Based on Structural Equation Model

Objective. The aim of the study is to investigate the influencing factors of quality of life in adult patients with epilepsy in Wenzhou in China. Methods. A total of 190 patients who visited our hospital from July 2019 to February 2021 were included in the study. Demographic data and disease status were collected. Moreover, QOLIE-31, PSQI, ESS, HAMD-17, and GAD-7 were used in the questionnaire survey. Structural equation model fitting was used to analyze the influencing factors of quality of life in adult patients with epilepsy. Results. The scores of the dimension of onset worry in men were greater than those of women (P = 0.049), and the scores of the dimension of life satisfaction were lower than women (P = 0.047). The scores of cognitive function decreased with age (P = 0.047). The scores of quality of life of unemployed and drinking patients significantly decreased $\left(P<\mathit{0.05}\right)$ . The score of quality of life positively correlated with good economic status and family relations $\left(P<\mathit{0.05}\right)$ . The score of emotional health increased first and then decreased with the course of the disease. With the decrease in seizure frequency and the extension of months without a seizure, the score of quality of life gradually increased. Furthermore, the structural equation model showed that health status was directly correlated to the quality of life of patients with epilepsy. Conclusion. Male, unemployment, drinking, older age, and disease are negatively related to the quality of life in patients with epilepsy. However, good economic status, good family relations, and good colleague relationships are positively related to the quality of life.

Long-term outcome of medically treated epilepsy

PURPOSE

To review the long-term outcome of epilepsy in population-based studies.

METHOD

Analysis of population-based studies.

RESULTS

About two of three patients with new-onset epilepsy will, in the long run, enter five-year terminal remission. Chances for remission are best for those with idiopathic or cryptogenic epilepsy. It is unclear whether the seizure outcome has improved over the last several decades. Social outcome, however, may have become better because of the improved level of knowledge on and public attitudes toward people with epilepsy, and possibly fewer prejudices at home, daycare, school, military and labor market.

CONCLUSION

While we still do not have a cure for epilepsy for all patients, relief of the medical and social consequences is available for many and hope is on the horizon for people with epilepsy.

Quality of life and sense of coherence in young people and adults with uncomplicated epilepsy: A longitudinal study

OBJECTIVES

The aim of the study was, in a ten-year follow-up, to describe and explore potential changes in quality of life and sense of coherence in relation to gender differences among persons with epilepsy in the transition from adolescence to adulthood.

MATERIALS AND METHODS

A longitudinal study of sense of coherence (SOC) and quality of life with repeated measurement design (1999, 2004, and 2009) was conducted in a population of persons (n = 69) who were aged 13-22 years in 1999 and 23-33 years in 2009. The Quality-of-Life Index (QLI) and the Sense of Coherence (SOC) scale were used.

RESULTS

There was a significant decrease (p ≤ 0.001) in seizures compared with the 2004 results, mainly among the women (p = 0.003). When comparing the total QLI scores, no significant differences were found between the three data collections and there were no differences in total scores between men and women. There was a decrease in the SOC total score over the 10-year period study. Total SOC was significantly higher among those being 30-33 years old compared to those being 23-29 years old (p = 0.014) and among those having a driving license (p = 0.029) compared to those not having a driving license.

CONCLUSIONS

Both quality of life and sense of coherence are important for maintaining health and well-being. Promoting health and well-being requires effective high-quality multidisciplinary person-centered care.

The Significance of Importance: An Evaluation of Ferrans and Powers’ Quality of Life Index

Ferrans and Powers' Quality of Life Index (QLI) defines and assesses quality of life (QoL) in terms of importance-weighted life satisfaction. This study assessed the value of such weights and explored the relationship between weighted and unweighted (satisfaction only) scores and single-item rated overall life satisfaction (LS) and QoL. Data were collected by a postal survey to 81 Parkinson's disease patients (88% response rate). Correlations between weighted and unweighted QLI scores were >or=0.96, except for one subscale (r ( s ) = 0.85). Item non-response rates ranged between 4.2 and 45.1% and 1.4 and 38% for the weighted and unweighted QLI, respectively. Cronbach's alpha exceeded 0.7 for weighted and unweighted versions of two out of the four subscales and the total score. Scaling success rates were similar for weighted and unweighted scores and did not support the current subscale structure. Unexpectedly, weighted total scores correlated stronger with LS than with QoL, and unweighted scores displayed the opposite pattern. This study found no advantages by using importance-weighted satisfaction scores. The correlational pattern with overall LS and QoL challenges the QLI approach to QoL, although these observations may relate to the use of multiplicative item weights. This study has implications also beyond the QLI regarding, e.g., the use of multiplicative weights and the relationship between life satisfaction and QoL.

Quality of life among the elderly with locomotor disabilities in Sweden and Poland in the 1990s

PURPOSE

To estimate the proportion of locomotor disabilities in two elderly populations in Sweden and Poland, respectively. To estimate the perceived quality of life (QoL) in the disabled groups in samples from each country using a model developed by Carol Estwing Ferrans.

METHODS

The study comprised three parts: an epidemiological screening test for identification of individuals with a locomotor disability, an analysis of background data of importance and home visits with evaluations of quality of life and functional capacity. Home visits were made using the Quality of Life Index, (QLI) of Ferrans and Powers and a functional scale, the Standardized Practical Equipment (SPE). Data were collected for the period 1991-1996.

RESULTS

In the population part of the study, with 1,380 respondents (78%) comprising elderly Swedish persons, 288 reported a locomotor disability. This can be compared with 425 among 1,045 respondents (52%) in a Polish elderly group. The tests at the home visits (Sweden, n = 89; Poland, n = 84) showed that both men and women in the Swedish group reported significantly higher scores for the total QLI (max. 30.00) with men reporting 26.68 points compared to 19.73 and women reporting 21.39 points compared to 19.40 and for three of the four subscales. Also, the Polish group scored lower for balance and mobility (SPE).

CONCLUSION

The study provides an important view of the life situation measured with the QLI tool and the SPE for elderly persons with locomotor disorders in Sweden and Poland during the mid-1990s. The results are congruent with epidemiological reports on the poor health situation in Poland, particularly during that time. A new investigation among the elderly with locomotor disorders in the two countries today might provide different results.

Examining the relationships of depressive symptoms, stigma, social support and regimen-specific support on quality of life in adult patients with epilepsy

Epilepsy research efforts have primarily focused on medical treatment and physical management of epilepsy; however, to provide comprehensive care, efforts cannot focus solely on physical manifestations of epilepsy. Research findings show that people with epilepsy face many challenges that can negatively affect quality of life (QOL). In this descriptive study, we examined the individual relationships between depressive symptoms, stigma, social support and regimen-specific support and QOL in adults with epilepsy. Study data were obtained from a subset of patients (N = 147) who participated in a longitudinal study of adult patients with epilepsy. Measures of QOL, depressive symptoms, stigma, social support and regimen-specific support were analyzed to answer the research questions. The results of correlational analyses revealed statistically significant negative correlations between depressive symptoms, stigma and sometimes regimen-specific support and QOL and statistically significant positive correlations between social support and QOL. A hierarchical multiple linear regression model revealed that depressive symptoms accounted for the most variance in QOL. Psychosocial variables measured 3 months prior to QOL were entered into a hierarchical multiple linear regression model, revealing that depressive symptoms, stigma and social support can be used to predict QOL at a later time.

Parental anxiety and quality of life of epileptic children

OBJECTIVE

To investigate the prevalence of parental anxiety associated with epileptic children, and to explore whether and how this specific condition affects children's quality of life (QOL), and what are the significant determinants for parental anxiety.

METHODS

Three hundred and forty parents whose children were affected with known epilepsy were enrolled in the study. Questionnaires for quality of life in childhood epilepsy (QOLCE), and hospital anxiety and depression (HAD) of parents were used to collect demographic data of both children and their parents, as well as clinical manifestations of epilepsy and family status.

RESULTS

Parental anxiety (of any severity) was observed in 191 subjects at interview, giving a prevalence rate of 56.2%. Of the 191 subjects, 18.5% reported mild anxiety, 24.4% moderate anxiety, and 13.2% severe anxiety. Factors associated with parental anxiety included frequency of seizure in children, average monthly income per person and parents' knowledge about epilepsy (P < 0.05). Parental anxiety significantly (P = 0.000) correlated with quality of life of children with epilepsy.

CONCLUSION

Parents of children with epilepsy are at high risk of having anxiety. Factors associated with parental anxiety originate both from children and from parents. Parental anxiety is significantly related with children's QOL. It is important for experts concerned to recognize such a relationship to improve the QOL of children and their parents.

The impact of epilepsy on older veterans

Despite the fact that old age is the time with the highest incidence of epilepsy, little is known specifically about the impact of epilepsy on the daily lives of the elderly. Previous studies have explored the impact of epilepsy on health status in a general population, but typically have not included enough older individuals to adequately describe this population. The study on which this chapter is based used a general survey instrument to begin exploration of this issue in a population of older veterans with epilepsy. Older patients (> or =65 years of age) were identified who had both International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), codes indicating epilepsy and prescriptions of antiepileptic drugs in national Veterans Affairs (VA) administrative and pharmacy databases during fiscal year 1999. Using these databases, patients were further identified as newly or previously diagnosed. Diagnostic data were then linked with data from the 1999 Large Health Survey of Veteran Enrollees, using encrypted identifiers, and the impact of epilepsy on patients of different ages was assessed using individual scales and component summaries of the Veterans SF-36. Results showed that older individuals with epilepsy had lower scores on measures of both physical and mental health than did their counterparts with no epilepsy. Further, scores associated with mental health functioning were significantly lower for those with newly diagnosed epilepsy than for those with chronic epilepsy, but differences associated with scores on physical functioning were not significant. Thus, while previous studies suggest that the effects of chronic neurological disorders such as epilepsy are most obvious on measures of mental health, these data suggest that older patients experience difficulties in both physical and mental health.

The psychological impact of a newly diagnosed seizure: losing and restoring perceived control

This study aimed to characterize the process of psychosocial adjustment following a newly diagnosed seizure. Eighty-five adult patients were assessed 1 and 3 months after a first seizure presentation with a purpose-developed semistructured interview, the NEWQOL, and the COPE. Among a broad range of patient concerns, psychological issues were paramount, representing a process of losing and restoring perceived control. Two psychological adjustment trajectories were identified, which hinged on the experience of a limited (n=37) or pervasive (n=48) loss of control. These adjustment trajectories were predicted by demographic and clinical factors. The pervasive group described a more extensive process of reevaluation, leading to an improved sense of self at 3 months. Pervasive loss of control, anxiety, and depression predicted subsequent seizure recurrence. Overall, a first seizure can trigger a complex adjustment process, which might require therapeutic management in some patients.

Factors affecting the quality of life in childhood epilepsy in China

OBJECTIVES

To explore the level of, and factors affecting the quality of life (QOL) in childhood epilepsy in China.

SUBJECTS AND METHODS

At the Peking University First Hospital, we consecutively identified 418 parents whose children were with known epilepsy to complete a questionnaire, which included children's demographic characteristics, clinical message of epilepsy, QOL, familial message, parental symptoms of anxiety/depression.

RESULTS

Significant (p<0.05) affecting factors of children's quality of life included current educational degree, mental development, age at diagnosis, age at onset, seizure frequency, duration, AED number; parental significant (p<0.05) affecting factors included anxiety, depression and health. On regression analysis, parental anxiety was the most important factor in explaining lower QOL in childhood epilepsy. AEDs, familial economic state, paternal career, seizure frequency were also significant factors.

CONCLUSION

Parental anxiety outweighed the physical factors in determining QOL in childhood epilepsy. Recognition of this will be helpful for professionals to treat disease and improve the QOL of childhood epilepsy.

Oxcarbazepine: a review of its use in children with epilepsy

Oxcarbazepine (Trileptal, Timox) is structurally related to carbamazepine and has anticonvulsant activity. Studies suggest that the anticonvulsant activity of oxcarbazepine is mediated via the blocking of neuronal ion channels. In patients aged <18 years, the efficacy of oxcarbazepine monotherapy was similar to that of phenytoin in children with partial onset or generalized tonic-clonic seizures in a 48-week trial. Additional supporting findings demonstrated that 43-71% of patients with partial onset, generalized or undetermined epilepsy were seizure free after oxcarbazepine monotherapy (mean dosage 27.7-50 mg/kg/day; duration 1-5 years). In contrast, one small nonblind trial showed more patients treated with oxcarbazepine monotherapy than with carbamazepine monotherapy had recurrent seizures during 16 months of therapy (although the conclusions that can be drawn from this trial are limited). As adjunctive therapy, oxcarbazepine was significantly better than placebo at reducing seizure frequency in children and adolescents with refractory partial onset seizures with or without secondary generalization: the median percentage change in partial onset seizure frequency was 35% vs 9%, respectively, during 16 weeks of therapy. In noncomparative trials of adjunctive oxcarbazepine (mean dosage of 34.5-56.7 mg/kg/day), 7-11% of patients with partial onset or generalized seizures were seizure free during treatment, and 20-54% had seizure reductions of > or=50%. Oxcarbazepine was generally well tolerated during monotherapy and adjunctive therapy; 2.5% and 10% of patients withdrew from well controlled trials of oxcarbazepine monotherapy and adjunctive therapy. Oxcarbazepine monotherapy was better tolerated than phenytoin and events observed in oxcarbazepine-treated patients were transient. Oxcarbazepine metabolism is largely unaffected by induction of the cytochrome (CYP) P450 system. However, oxcarbazepine can inhibit CYP2C19 and induce CYP3A4 and CYP3A5, thereby interfering with the metabolism of other drugs (e.g. phenytoin). In addition, oxcarbazepine decreases plasma levels of oral contraceptives and alternative contraceptive methods should be used. In conclusion, oxcarbazepine (as both monotherapy and adjunctive therapy) has shown efficacy in the treatment of partial onset seizures in children with epilepsy. Nevertheless, the generally favorable tolerability profile and relatively low potential for drug interactions of oxcarbazepine make it a valuable option in the treatment of childhood epilepsy.

Psychometric testing of the NEECHAM Confusion Scale among patients with hip fracture

The main aim of this study was to assess the reliability and validity of a Swedish translation of the NEECHAM Confusion Scale among 73 patients having surgery for hip fractures. Cronbach's alpha before and 7 days after surgery were.73 and.82, respectively. Principal-component analyses yielded three factors explaining 69% of the variance of the variables preoperatively and 73.6% of the variance 7 days postoperatively. Four months after discharge vital function, factor II in the NEECHAM scale, significantly predicted the total score on the Ferrans and Powers Quality of Life Index. Items reflecting information processing, behavior, and urinary continence, factor I, also predicted functional capacity, using the Standardized Practical Equipment test, a tool measuring instrumental daily activity. The scale seems to be a reliable and valid instrument for evaluating acute confusional state among patients with hip fracture.

Oxcarbazepine: an update of its efficacy in the management of epilepsy

Oxcarbazepine (10,11-dihydro-10-oxo-5H-dibenz[b,f]azepine-5-carboxamide) is a 10-keto analogue of carbamazepine with anticonvulsant activity. In newly diagnosed adult patients, oxcarbazepine monotherapy is as effective as phenytoin and vaiproic acid at reducing generalised tonic-clonic and partial seizure frequency. Furthermore, oxcarbazepine 2400 mg/day as monotherapy has also proved effective in the treatment of refractory partial seizures in adult patients. Oxcarbazepine 600, 1200 and 2400 mg/day as adjunctive therapy significantly reduced seizure frequency compared with placebo in 692 patients with refractory partial seizures. The efficacy of oxcarbazepine monotherapy is similar to that of phenytoin in the treatment of children and adolescents with newly diagnosed partial or generalised tonic-clonic seizures. Additionally, adjunctive therapy with oxcarbazepine was significantly more effective than placebo at reducing seizure frequency in children and adolescents with refractory partial seizures. The most commonly reported adverse events associated with oxcarbazepine monotherapy and/or adjunctive therapy in adults and/or children are somnolence, dizziness, headache, nausea and vomiting. Oxcarbazepine monotherapy is better tolerated than phenytoin (in both adults and children) and valproic acid (in adults), and although 75 to 90% of adult patients in 5 recent monotherapy studies reported adverse events while receiving oxcarbazepine, <8% withdrew from treatment because of them. Acute hyponatraemia, although usually asymptomatic, develops in 2.7% of patients treated with oxcarbazepine. Adverse events most likely to resolve upon switching to oxcarbazepine therapy from treatment with carbamazepine are undetermined skin reactions (rashes, pruritus, eczema), allergic reactions and a combination of malaise, dizziness and headache. Although oxcarbazepine does have a clinically significant interaction with some drugs (e.g. phenytoin and oral contraceptives), it has a lower propensity for interactions than older antiepileptic drugs (AEDs) because its major metabolic pathway is mediated by noninducible enzymes.

CONCLUSION

Oxcarbazepine as monotherapy is a viable alternative to established AEDs in the treatment of partial and generalised tonic-clonic seizures in adults and children. Furthermore, it is also effective as adjunctive therapy in the treatment of refractory partial seizures in both age groups. In addition, the drug is tolerated better than the older, established AEDs, and has a lower potential for drug interactions. These attributes make oxcarbazepine an effective component in the initial treatment of newly diagnosed partial and generalised tonic-clonic seizures, and also as an adjunct for medically intractable partial seizures in both adults and children.

Quality of life in patients with epilepsy and impact of treatments

Epilepsy is a chronic condition with numerous social and psychological consequences. This work aimed to review available data on epilepsy and the impact of surgical and pharmaceutical treatments on the quality of life in adults and children. Research on quality of life in epilepsy is characterised by a wide and fragmentary range of methodology, both in terms of study design and instruments used. Quality of life is worse in patients with epilepsy than in the general population; it is comparable or worse in patients with epilepsy than that in patients with other chronic conditions; and it is similar to that of healthy persons when patients with epilepsy are well-controlled. Frequency of seizures seems to be one of the most relevant determinants of poor quality-of-life (QOL) scores, and quality of life is worsened by the co-existence of depression. The impact of surgical treatment on quality of life is positive, in all ages, in correlation with seizure control. There is no exhaustive or even contradictory results available concerning the impact of drug treatment. Role activities, emotional status and cognition have been the most investigated domains of quality of life in epilepsy research. There is a substantial lack of information regarding the functional status domain. At present, quality of life and psychosocial functioning in people with epilepsy have been investigated in many studies. Nevertheless, the lack of a standardised approach makes it extremely difficult to summarise and indicate what measures should be used, in which patients, and in which sub-populations. In the pursuit of developing valid, reliable and sensitive measures of quality of life, it seems no longer appropriate to consider seizure frequency alone.
