Antipsychotic polypharmacy in inpatients with schizophrenia in Asia (2001-2009)

OBJECTIVE

This study aimed to identify trends in the use of antipsychotic polypharmacy (APP) and their demographic and clinical correlates in the treatment of schizophrenia in Asia between 2001 and 2009.

METHOD

A total of 6,761 schizophrenia inpatients in 9 Asian countries and territories were examined; 2,399 in 2001, 2,136 in 2004, and 2,226 in 2009. Patients’ socio-demographic and clinical characteristics and prescriptions of psychotropic drugs were recorded using a standardized protocol and data collection procedure.

RESULTS

The proportion of APP prescription decreased from 46.8 % in 2001, to 38.3 % in 2004, and increased to 43.4 % in 2009, with wide intercountry variations at each survey. Multiple logistic regression analysis of the whole sample revealed that patients on APP were younger, had a higher dose of antipsychotics in chlorpromazine equivalents, and more severe positive and negative symptoms. They were also more likely to receive depot and fi rst-generation antipsychotic drugs.

CONCLUSIONS

The frequency of APP prescription varied between countries and territories, suggesting that a host of clinical and socio-cultural factors played a role in determining APP use in Asia. To resolve the discrepancy between treatment recommendation and clinical practice, regular reviews of prescription patterns are needed.

Depression in patients of myocardial infarction--a cross-sectional study in northern India

OBJECTIVES

To assess the prevalence of major depressive disorder and subsyndromal depression in patients with first episode of myocardial infarction (MI) and to compare the socio-demographic, clinical and coronary risk factors in patients with and without depression.

METHODS

Patients of acute MI (n = 101) attending OPD at 4 to 6 weeks after the index event were the subjects. Diagnoses of Major Depressive Disorder were established according to Diagnostic and Statistical Manual for Mental Disorders fourth edition Test Revision (DSN-IV-TR) criteria. Schedule for Affective Disorder and Schizophrenia changed version modified for Bipolar disorder (SADS-CB) was applied to detect cases with depressive symptoms not amounting to major depressive disorder (sub-syndromal). It was a single point cross sectional study.

RESULTS

No depressive symptoms (Group-A) were found in 56 patients (55.4%). Major Depressive Disorder (Group-B) was found in 24 patients (23.8%) and subsyndromal symptoms (Group-C) in 21 patients (20.8%). Sociodemographic and clinical variables were similar amongst three groups except, more patients in Group-C were from nuclear family (p = 0.01) and were educated (p = 0.03). More patients in Group-B had hypertension (p = 0.001), diabetes (p = 0.03) or were overweight (p = 0.02) as compared to Group-A. Similarly higher number of Group-C patients had hypertension (p = 0.04), diabetes (p = 0.01) and were current smokers (p = 0.01) as compared to Group-A.

CONCLUSION

Unrecognized and untreated major depressive disorder and sub-syndromal symptoms were frequent in patients of MI. Established coronary factors were more commonly present in these groups as compared to no depressive symptom group. This emphasizes the need for routine screening for depression in post MI phase in our population.

Indian experiences with International Classification of Mental and Behaviour Disorders-10: Pathway for ICD-11

BACKGROUND

International Classification of Mental and Behavioural Disorders (ICD)-10 has been serving its purpose in the spheres of diagnosing psychiatric patients, research, and education since long. With ICD-11 is on the horizon, this is the right time to assess issues in the application of these guidelines in routine clinical practice.

AIM

In this study, an effort was made to find out day-to-day difficulties in application of ICD-10.

MATERIALS AND METHODS

A total of 130 patients attending for the first time the outpatient Department of Psychiatry, CSMMU, Lucknow, were taken as sample for the present study. The "provisional diagnosis", which was made after the usual assessments on a single day at the clinical setting was recorded. The selected patients were later assessed in detail and a "final diagnosis was recorded for these patients. The diagnoses were matched with ICD-10 and rated on a five-point scale.

STATISTICS

The direct count and percentage analysis was done.

RESULTS

Results show that 67.69% "provisional diagnosis" were fully matched, while 8% and 5% diagnosis had no match and some match, respectively with the "final diagnosis". There were also some cases that had significant match (1.5%) and almost match (17.69%).

CONCLUSION

In a busy clinical setting, the focus of the clinicians is more on management and accurate diagnosis based on ICD-10 may be ignored.

The low frequency of reported sexual dysfunction in Asian patients with schizophrenia (2001-2009): low occurrence or ignored side effect?

OBJECTIVE

The purpose of the study was to evaluate the frequency of reported sexual dysfunction (SD) in schizophrenia and its associations with sociodemographic and clinical variables in selected Asian countries.

METHODS

A total of 5877 schizophrenia patients in nine Asian countries and territories were examined between 2001 and 2009. The patients' sociodemographic and clinical characteristics, prescription of psychotropic drugs, and drug-induced side effects were recorded using a standardized protocol and data collection. SD was evaluated as "present" or "absent" according to the clinical judgment of experienced psychiatrists.

RESULTS

The frequency of reported SD in the whole sample in women and men was 3.0%, 0.8%, and 4.6%, respectively, with variations across study sites. In the multivariate analyses, male sex, more second-generation antipsychotics, benzodiazepines, and antidepressants were independently associated with higher likelihood of reported SD, whereas negative symptoms had an inverse association with reported SD.

CONCLUSIONS

The results of this study indicate that SD was seldom recorded as a side effect by Asian psychiatrists while treating patients with schizophrenia. It is unclear whether the low prevalence of reported SD compared with Western data is real or whether the results are being insufficiently recognized.

Indian psychiatry, research and Asian countries

Asia has some of the largest conglomerations of human populations and also the fastest growing economies of the world. About 23% of the world's population lives in the South Asian region, and one-fifth of psychiatrically ill patients in the world live in this part of the world. Despite vast cultural, religious, geographical, and political diversities, the factors influencing mental health remain the same throughout this wide region, as highlighted at the recently concluded Asian summit, where the slogan, 'One vision, one identity, one community,' was launched. Thus, the need to strengthen regional cooperation in the field of mental health has always been felt. This article highlights facts about influence of Indian Psychiatry research as well as of some Asian countries in the world psychiatry and vice versa.

The geriatric population and psychiatric medication

With improvement in medical services in the last few years, there has been a constant rise in the geriatric population throughout the world, more so in the developing countries. The elderly are highly prone to develop psychiatric disorders, probably because of age related changes in the brain, concomitant physical disorders, as well as increased stress in later life. Psychiatric disorders in this population may have a different presentation than in other groups and some of psychopathologies might be mistaken for normal age related changes by an unwary clinician. Therefore the need of the day is to train psychiatrists and physicians to better recognize and manage mental disorders in this age group.

Rapid urbanization - Its impact on mental health: A South Asian perspective

Rapid increase in urban population as a proportion of total population is resulting in rapid urbanization of the world. By the end of 2008, a majority of the world's population will be living in the cities. This paradigm shift in the dynamics of human population is attracting attention of demographers, sociologists, scientists, and politicians alike. Urbanization brings with it a unique set of advantages and disadvantages. Though it is driving the economies of most of the nations of the world, a serious concern regarding the impact of urbanization on mental health is warranted. The impact of urbanization on mental health in South-Asian countries needs to be examined. These countries by virtue of their developing economies and a significant proportion of population still living below poverty line are particularly vulnerable and tend to have a higher burden of diseases with an already compromised primary health care delivery system. The range of disorders and deviancies associated with urbanization is enormous and includes psychoses, depression, sociopathy, substance abuse, alcoholism, crime, delinquency, vandalism, family disintegration, and alienation. Thus, it is a heterogenous mix of problems and categorizing them to one particular subtype seems daunting and undesirable. Urbanization is affecting the entire gamut of population especially the vulnerable sections of society - elderly, children and adolescents, and women. Rapid urbanization has also led to creation of "fringe population" mostly living from hand to mouth which further adds to poverty. Poverty and mental health have a complex and multidimensional relationship. Urban population is heavily influenced by changing cultural dynamics leading to particular psychiatric problems like depression, alcoholism, and delinquency. Judicious use of resources, balanced approach to development, and sound government policies are advocated for appropriate growth of advancing economies of South-Asian region.

Neurocognition in first-degree healthy relatives (siblings) of bipolar affective disorder patients

AIM

Cognitive deficits have been presupposed to be endophenotypic markers in bipolar disorder, but few studies have ascertained the cognitive deficits in healthy relatives of bipolar disorder patients. The aim of the present study was to assess the cognitive functions of first-degree relatives of patients with bipolar disorder and compare them with healthy controls.

METHODS

Ten first-degree apparently healthy relatives of patients with bipolar disorder were compared with 10 age- and education-matched control subjects on computer-based cognitive tests.

RESULTS

As compared to the control group, the relatives group performed significantly poorly on tests for executive function and vigilance, while on the test for working memory the performance was not significantly different on most of the parameters.

CONCLUSIONS

Executive functioning and vigilance could be potential markers of the endophenotype in bipolar patients.

Cognitive functions in euthymic state of bipolar disorder: an Indian study

INTRODUCTION

It has recently been observed that some cognitive deficits in bipolar disorders persist even after the subsidence of active symptoms. The authors aim to study the cognitive functioning of patients with bipolar disorder, currently in euthymia and compare them with normal healthy controls.

METHODS

Fifteen patients having bipolar-I disorder and currently in euthymia were compared with fifteen age- and education-matched controlled subjects. Cognitive assessments were done using three computer-based tests, i.e., Wisconsin's Card Sorting Test (WCST), Spatial Working Memory Test (SWMT), and Continuous Performance Test (CPT).

RESULTS

Euthymic bipolar patients showed significant deficits in executive functions. Subtle deficits were present in attention and working memory that were not statistically significant.

CONCLUSIONS

Executive deficits may be trait markers in bipolar disorder and may have clinical implications in patient rehabilitation.

Cognitive functions in stable schizophrenia & euthymic state of bipolar disorder

BACKGROUND & OBJECTIVES

Some cognitive deficits in schizophrenia and bipolar disorders persist after the subsidence of active symptoms. We carried out this study to assess and compare the cognitive functioning of patients with stable schizophrenia and bipolar disorder.

METHODS

Fifteen each of stable maintained schizophrenic patients and euthymic bipolar-I patients attending outpatient clinic in a tertiary care psychiatric hospital in north India were included in the study as also equal number of age and education matched control subjects. Cognitive assessments were done using Wisconsin's Card Sorting Test (WCST), Spatial Working Memory Test (SWMT) and Continuous Performance Test (CPT).

RESULTS

Stable schizophrenia patients performed poorly on all the neurocognitive parameters as compared to both controls and bipolar euthymic patients. Euthymic bipolar patients showed significant difference on executive functions with normal controls. Patterns of cognitive disturbances in tasks of executive function are similar in both groups but are quantitatively more marked in schizophrenia.

INTERPRETATION & CONCLUSIONS

Our results showed that stable schizophrenia patients performed significantly worse on cognitive measures than patients of euthymic bipolar disorder which was consistent with their poorer functional outcome. The results further indicated that stable schizophrenia and euthymic bipolar disorders may be distinguished qualitatively in neuropsychological terms with different profiles of cognitive impairment.

Depression among women in the South-Asian region: the underlying issues

BACKGROUND

The condition of women in third-world countries continues to be dismal. They are constantly exposed to such circumstances which make them prone to sufferings. These sufferings bear an irreparable brunt upon the mental health condition of females which are presented as greater psychological problems in terms of depressive disorders. The impact, in turn is felt by the society as a whole which lags behind due to the huge burden. This study is presented to highlight the various factors affecting the presentation of women in the region.

METHODS

This is a review of studies in which various issues pertaining to presentation, course, and outcome of depression among women in South-Asian region are discussed. The studies were chosen from Internet-based search.

RESULTS

The various factors affecting the problems can be grouped into: social milieu, reproductive health factors, and biological milieu.

LIMITATIONS

This study incorporates various studies which were undertaken at different time durations; hence, its finding cannot be reproduced in an exact sense. It is worth mentioning that these factors need to be studied comprehensively for better health care.

CONCLUSION

This study gives an indication of specific health care needs of women in the region which are to be customized as per local needs and cultural sanctions.

Culturally-sensitive complaints of depressions and anxieties in women

BACKGROUND

Current classifications of Mental Disorders are centered on Westernized concepts and constructs. "Cross-cultural sensitivity" emphasizes culturally-appropriate translations of symptoms and questions, assuming that concepts and constructs are applicable.

METHODS

Groups and individual psychiatrists from various cultures from Asia, Latin America, North Africa and Eastern Europe prepared descriptions of main symptoms and complaints of treatment-seeking women in their cultures, which are interpreted by clinicians as a manifestation of a clinically-relevant dysphoric disorder. They also transliterated the expressions of DSM IV criteria of main dysphoric disorders in their cultures.

RESULTS

In many non-western cultures the symptoms and constructs that are interpreted and treated as dysphoric disorders are mostly somatic and are different from the Western-centered DSM or ICD systems. In many cases the DSM and ICD criteria of depression and anxieties are not even acknowledged by patients.

LIMITATIONS

The descriptive approach reported here is a preliminary step which involved local but Westernized clinicians-investigators following a biomedical thinking. It should be followed by a more systematic-comprehensive surveys in each culture.

CONCLUSIONS

Westernized concepts and constructs of mental order and disorders are not necessarily universally applicable. Culturally-sensitive phenomena, treatments and treatment responses may be diversified. Attempts at their cross-cultural harmonization should take into consideration complex interactional multi-dimensional processes.

An open-label multicentric study of the tolerability and response to escitalopram treatment in Indian patients with major depressive disorder

To evaluate the tolerability and response to escitalopram in Indian patients with major depression, over an 8-week open-label multicentric study was carried out among 18-65 years old Indian patients suffering from DSM IV major depressive disorder with Montgomery-Asberg depression rating scale (MADRS) total score> or =22. Patients received a fixed dose of escitalopram 10 mg daily for 2 weeks, followed by flexible dose of 10 to 20 mg daily for 6 weeks. Patients were evaluated for depression and rated on MADRS score and clinical global impressions-severity (CGI-S) and--improvement (CGI-I) scores. They were monitored for treatment-emergent adverse effects. A total of 119 patients were enrolled and 103 completed the trial. There was a decrease from baseline in the MADRS total score after one week of treatment continuing until 8 weeks. By week 8, 76.9% patients had responded to treatment (> or =50% or more reduction of MADRS total score). A similar pattern of improvement to that seen with the MADRS total score was seen with CGI-S and CGI-I scores. Escitalopram was well tolerated, with only 2 patients (1.7%) withdrawing from the study due to adverse events. There were no serious adverse events.

Regional cooperation in South Asia in the field of mental health

The South Asian region accounts for around one fourth of the world population and one fifth of psychiatrically ill patients in the world. The region lacks mental health policies and infrastructure. Issues like community care, trained manpower, patient satisfaction and better legislation have been a focus of attention in recent years. As this region is fast developing, cooperation is needed in the field of mental health to keep pace with the other areas. Cooperation is needed to develop culturally acceptable forms of psychotherapy and new technologies for delivery of mental health services. Another area of potential cooperation is the development of a classification of mental disorders that is more informative in our setting. The development of a mental health programme and its inclusion at various levels of health care delivery has also gained precedence. As most of countries in the area have limited financial resources, the funds are to be used in the most cost-effective manner, and for this a greater collaboration amongst the countries is needed. New research needs to be undertaken in the area especially to meet the local requirements and to understand diseases in a regional perspective, but research cannot be fruitful if regional cooperation is lacking. To enhance the cooperation in mental health, world bodies like the WPA will need to come forward and bring all the countries at a common platform. The WPA has done commendable work in this regard and has always extended support to the regional bodies to uplift the mental health in this region.

Cognitive deficits in psychiatric disorders: Current status

Cognition denotes a relatively high level of processing of specific information including thinking, memory, perception, motivation, skilled movements and language. Cognitive psychology has become an important discipline in the research of a number of psychiatric disorders, ranging from severe psychotic illness such as schizophrenia to relatively benign, yet significantly disabling, non-psychotic illnesses such as somatoform disorder. Research in the area of neurocognition has started unlocking various secrets of psychiatric disorders, such as revealing the biological underpinnings, explaining the underlying psychopathology and issues related to course, outcome and treatment strategies. Such research has also attempted to uproot a number of previously held concepts, such as Kraepelin's dichotomy. Although the range of cognitive problems can be diverse, there are several cognitive domains, including executive function, attention and information processing, and working memory, which appear more frequently at risk. A broad range of impairment across and within the psychiatric disorders are highlighted in this oration. The oration summarizes the studies investigating cognitive processing in different psychiatric disorders. I will also discuss the findings of my own research on neurocognitive deficits in mood disorders, schizophrenia, obsessive-compulsive disorder, somatoform disorder, including studies on 'high-risk' individuals. Tracing the evaluation of neurocognitive science may provide new insights into the pathophysiology and treatment of psychiatric disorders.

Disability assessment in mental illnesses using Indian Disability Evaluation Assessment Scale (IDEAS)

BACKGROUND & OBJECTIVE

Psychiatric disorders cause disability in individuals and pose significant burden on their families. In most of the cases residual disability and poor quality of life continue even after disability evaluation in patients with chronic mental illness in very important. The present study was undertaken to assess and compare the disability in patients with schizophrenia and obsessive-compulsive disorder (OCD) using Indian Disability Evaluation Assessment Scale (IDEAS).

METHODS

Patients diagnosed to have schizophrenia and OCD with mild severity of illness were included in the study. Indian Disability Evaluation Assessment Scale (IDEAS) was applied. Disability was assessed in these patients on all domains of IDEAS.

RESULTS

Majority of the patients with schizophrenia were from rural areas whereas most of the patients with OCD were from urban background. There was comparable disability in the patients with schizophrenia with duration of illness in the range of 2-5 yr and >5 yr. Significant disability in work and global score was seen in patients of obsessive-compulsive disorder with duration of illness >5 yr. Patients with schizophrenia had significantly higher disability in all domains than patients with OCD.

INTERPRETATION & CONCLUSION

Schizophrenia causes greater disability than obsessive-compulsive disorder in patients. These illnesses affect all areas of daily functioning leading to greater disability, and thus increasing the burden on the family, pose greater challenge for the rehabilitation of patients and their inclusion in the mainstream of the family and society. Further studies on a larger sample need to be done to confirm the finding.

Suicide: an Indian perspective

Suicide, as an issue, has attracted the attention of society since time immemorial. Its situation in India and the socio-demographic variables have been discussed along with management profile. The education of physicians and general practitioners in suicide prevention has been stressed.

Better mental health care for older people in India

Demographic aging will soon lead to a sudden increase in the number of older people with dementia and depression in India. We need to develop services to meet the mental health needs of the aged in the population. Geriatric Psychiatry section of IPS has initiated a process of consultations to address this emerging public health issue. Health professionals involved in the care of older people with mental health problems took part in focus group discussions Their opinion and suggestions regarding development of psychogeriatric services and research were gathered. Urgent action is needed to improve the existing low levels of public awareness about mental health problems of older people. Home based care needs to be supported through formal services in the community. If sensitised properly clinicians, can be more effective in managing depression and dementia at primary care level. Research initiatives can be facilitated by networking of researchers and active efforts at dissemination of important research findings. Community health workers could be trained to identify and provide help to older people with mental health problems and their carers. Community outreach programmes for elderly could be particularly relevant in the rural areas where as development of clinic based psycho-geriatric services may be feasible in urban settings. Good research can influence and shape policies which in turn can result in better mental health care for older people.

Depression in general clinical practice

Worldwide currently about 340 million people suffer from depression. If not treated, it leads to increased morbidity and mortality. Risk factors include female sex, young age, lower socio-economic study, separated or divorced, positive family history, stressful life events, certain medical illness and so on. Aetiology lies on genetic factors, biochemical abnormality and personality and environmental factors. Clinical features lie on cardinal and other common symptoms. Depression usually starts before 40 years of age, average duration of one episode being 3-9 months. Treatment consists of a variety of psychotherapeutic approaches, pharmacotherapy and electroconvulsive therapy. A clinician may start therapy with low dose SSRIs which is considered as 1st line drugs. To educate patients about anti-depressants is very important.

Escitalopram Versus Citalopram and Sertraline: A Double-Blind Controlled, Multi-centric Trial in Indian Patients with Unipolar Major Depression

The present randomized, double blind, parallel group, controlled, multi-centric trial was designed to evaluate the efficacy and tolerability of escitalopram in comparison with citalopram and sertraline in the treatment of major depressive disorder. Outpatients (N=214) with an ongoing/newly diagnosed ICD-10 major depressive episode and a Hamilton Rating Scale for Depression (HAM-D) score of > 18 were randomly assigned to citalopram, 20-40 mg/day (74 patients), escitalopram, 10-20 mg/day (69 patients) and sertraline, 50-150 mg/day (71 patients), for a 4-week double-blind treatment period, with dosage adjustment (after 2 weeks of treatment) according to the response to treatment. Clinical response was evaluated by the 17 items HAM-D and the Clinical Global Impression (CGI) scales, which were recorded at baseline and at weekly intervals. Tolerability was evaluated by observed/spontaneously reported adverse changes in laboratory parameters (baseline and after 4 weeks). Response rate was defined as a decrease in HAM-D score by 50% from baseline and remission rate was defined as a HAM-D score of < 8. Response rate at the end of two week were 58% for escitalopram (10mg/day), 49% for citalopram (20mg/day) and 52% for sertraline (50-100mg/day). Response rate at the end of four week were 90% for escitalopram (10-20mg/day), 86% for citalopram (20-40mg/day) and 97% for sertraline (100-150mg/day). The Remission rates at the end of four weeks were 74% for escitalopram, 65% for citalopram and 77% for sertraline. Adverse experiences were reported by 45% of patients in escitalopram group, 58% patients in citalopram and 56% patients in the sertraline group. Additionally, there were lesser dropouts and lesser requirement for dose escalation in escitalopram than in citalopram and sertraline group. In conclusion Escitalopram, the Senantiomer of the citalopram is a safe and effective antidepressant in the Indian population. It has potentially superior efficacy than citalopram and a comparable efficacy to sertraline with fewer side effects than both citalopram and sertraline.

Urban mental health services in India : how complete or incomplete?

The information about Urban Mental Health Services has been nearly nonexistent in India, although the developed countries have been focusing on programmes for "Healthy Cities". The initiative taken as part of the WHO-ICMR Pilot Project on Urban Mental Health Services, with a public health perspective is being shared. The objectives of the Health Services Research (HSR) Arm of the project were to study the distribution and the availability of tertiary Mental Health Services, availability of human resources, average service load, mental health service gap, and perceptions of the users and the service providers, regarding the barriers in accessibility of mental health services, unmet service needs and strategies for improvement.The Research Methods involved Mapping Exercises with estimation of Service Loads and Qualitative Research Methods (QRM) like In-Depth Interviews (IDIs), Key Informant Interviews (KIIs), Free Listing and Focused Group Discussions (FGDs). The results indicate uneven availability of mental health services, human resource deficit specially for non-medical mental health professionals and mental health service gap (82% to96%). The average service load in the specialist mental health services is largely carried by the Govt. sector (half to two thirds), followed by the private sector (one third to half), with only a small portion by the NGO sector. The average mental health service load in the primary care general health services is largely carried by the private sector, with significant contribution from the non-formal service providers. The barriers to access, unmet needs and possible strategies as perceived by the community, users and service providers have been identified. The findings are discussed in the context of the mental health programmes and the public policy issues. The implications of the conclusions which suggest that Urban Mental Health Services are far from complete are highlighted.
