The Blunt Liver and Spleen Trauma (BLAST) audit: national survey and prospective audit of children with blunt liver and spleen trauma in major trauma centres

PURPOSE

To compare the reported and observed management of UK children with blunt liver or spleen injury (BLSI) to the American Pediatric Surgical Association (APSA) 2019 BLSI guidance.

METHODS

UK Paediatric Major Trauma Centres (pMTCs) undertook 1 year of prospective data collection on children admitted to or discussed with those centres with BLSI and an online questionnaire was distributed to all consultants who care for children with BLSI in those centres.

RESULTS

All 21/21 (100%) pMTCs participated; 131 patients were included and 100/152 (65%) consultants responded to the survey. ICU care was reported and observed to be primarily determined using haemodynamic status or concomitant injuries rather than injury grade, in accordance with APSA guidance. Bed rest was reported to be determined by grade of injury by 63% of survey respondents and observed in a similar proportion of patients. Contrary to APSA guidance, follow-up radiological assessment of the injured spleen or liver was undertaken in 44% of patients before discharge and 32% after discharge, the majority of whom were asymptomatic.

CONCLUSIONS

UK management of BLSI differs from many aspects of APSA guidance. A shift towards using clinical features to determine ICU admission and readiness for discharge is demonstrated, in line with a strong evidence base. However, routine bed rest and re-imaging after BLSI is common, contrary to APSA guidance. This disparity may exist due to concern that evidence around the incidence, presentation and natural history of complications after conservatively managed BLSI, particularly bleeding from pseudoaneurysms, is weak.

Tobacco mosaic virus for the targeted delivery of drugs to cells expressing prostate-specific membrane antigen

Prostate-specific membrane antigen (PSMA) is a membrane-bound protein that is preferentially expressed in the prostate gland and induced in many prostate cancers, making it an important target for new diagnostics and therapeutics. To improve the efficacy of nanoparticle formulations for the imaging and/or eradication of prostate cancer, we synthesized the PSMA-binding glutamic acid derivative DUPA and conjugated it to the external surface of tobacco mosaic virus (TMV) particles. DUPA-targeted TMV was subsequently loaded with the antineoplastic agent mitoxantrone (MTO) or conjugated internally with the fluorescent dye cyanine 5 (Cy5). We found that TMV particles could be efficiently decorated with DUPA and loaded with MTO or Cy5 while maintaining structural integrity. DUPA-targeted TMV particles were able to bind more efficiently to the surface of PSMA⁺ LNCaP cells compared to non-targeted TMV; but there was little difference in binding efficiency between targeted and untargeted TMV when we tested PSMA⁻ PC3 cells (both cell lines are prostate cancer cell lines). DUPA-targeted TMV particles were internalized by LNCaP cells enabling drug delivery. Finally, we loaded the DUPA-targeted TMV particles and untargeted control particles with MTO to test their cytotoxicity against LNCaP cells in vitro. The cytotoxicity of the TMV-MTO particles (IC₅₀ = 10.2 nM) did not differ significantly from that of soluble MTO at an equivalent dose (IC₅₀ = 12.5 nM) but the targeted particles (TMV-DUPA-MTO) were much more potent (IC₅₀ = 2.80 nM). The threefold increase in cytotoxicity conferred by the DUPA ligand suggests that MTO-loaded, DUPA-coated TMV particles are promising as a therapeutic strategy for PSMA⁺ prostate cancer and should be advanced to preclinical testing in mouse models of prostate cancer.

Methodological Recommendations for Trials of Psychological Interventions

Recent years have seen major developments in psychotherapy research that suggest the need to address critical methodological issues. These recommendations, developed by an international group of researchers, do not replace those for randomized controlled trials, but rather supplement strategies that need to be taken into account when considering psychological treatments. The limitations of traditional taxonomy and assessment methods are outlined, with suggestions for consideration of staging methods. Active psychotherapy control groups are recommended, and adaptive and dismantling study designs offer important opportunities. The treatments that are used, and particularly their specific ingredients, need to be described in detail for both the experimental and the control groups. Assessment should be performed blind before and after treatment and at long-term follow-up. A combination of observer- and self-rated measures is recommended. Side effects of psychotherapy should be evaluated using appropriate methods. Finally, the number of participants who deteriorate after treatment should be noted according to the methods that were used to define response or remission.

Use of a Single CAR T Cell and Several Bispecific Adapters Facilitates Eradication of Multiple Antigenically Different Solid Tumors

Most solid tumors are comprised of multiple clones that express orthogonal antigens, suggesting that novel strategies must be developed in order to adapt chimeric antigen receptor (CAR) T-cell therapies to treat heterogeneous solid tumors. Here, we utilized a cocktail of low-molecular-weight bispecific adapters, each comprised of fluorescein linked to a different tumor-specific ligand, to bridge between an antifluorescein CAR on the engineered T cell and a unique antigen on the cancer cell. This formation of an immunologic synapse between the CAR T cell and cancer cell enabled use of a single antifluorescein CAR T cell to eradicate a diversity of antigenically different solid tumors implanted concurrently in NSG mice. Based on these data, we suggest that a carefully designed cocktail of bispecific adapters in combination with antifluorescein CAR T cells can overcome tumor antigen escape mechanisms that lead to disease recurrence following many CAR T-cell therapies. SIGNIFICANCE: A cocktail of tumor-targeted bispecific adapters greatly augments CAR T-cell therapies against heterogeneous tumors, highlighting its potential for broader applicability against cancers where standard CAR T-cell therapy has failed.

Abstract 3571: Use of a universal CAR T cell plus bispecific adapters to eradicate antigenically heterogeneous tumors

Chimeric antigen receptor (CAR) T cell therapies have attracted considerable attention because of their abilities to focus the killing power of T cells specifically onto tumor antigen expressing cancer cells. Despite impressive successes in the clinic, CAR T cell technologies still suffer from an inability to kill cancer cells that mutate to avoid expression of the CAR T cell recognized antigen. While current CAR T cell technologies would require the engineering of a new CAR to recognize a second tumor-specific antigen, we have instead developed a universal CAR that can recognize any tumor antigen. In this modification of standard CAR T cell technology, we fuse an scFv that binds fluorescein to the exoplasmic domain of a T cell receptor that contains the usual 4-1BB and CD3 zeta activation domains within its cytoplasmic domain. We then promote engagement of the resulting CAR T cell with the desired cancer cell by administering a bispecific adapter molecule that contains fluorescein linked to a tumor-specific ligand via a short spacer. Upon addition of this adapter, simultaneous binding of the fluorescein to the CAR and the tumor-specific ligand to the cancer cell mediates multivalent binding of the CAR T cell to the cancer cell. With the simultaneous administration of a cocktail of different tumor-specific adaptors, each comprised of a fluorescein linked to a distinct tumor-specific ligand, multiple orthogonal cancer cells within a heterogeneous solid or liquid tumor can be simultaneously eliminated by a single CAR T cell. To test the ability of our proposed universal CAR T cell to eradicate solid tumors with multiple orthogonal tumor antigens, we first demonstrate the capacity of our anti-fluorescein CAR T cell to kill a variety of cultured human cancer cells in vitro upon addition of the optimal adapter. In this effort, we show that the same anti-fluorescein CAR T cell can kill: i) multiple folate receptor-expressing cancer cells upon addition of folate-fluorescein, ii) PSMA-expressing cancer cells upon addition of a PSMA ligand-fluorescein conjugate, iii) carbonic anhydrase IX-expressing cancer cells upon addition of a CA9 ligand-fluorescein conjugate, and iv) neurokinin-1 receptor expressing cancer cells upon addition of a NK1R ligand-fluorescein conjugate. We then demonstrate that this same universal killing potency is also effective in vivo by transfecting separate MDA-MB-231 breast cancer cell cultures with one of the above tumor antigens and then implanting the MDA-MB-231 cells expressing the orthogonal tumor antigens in NSG mice and showing that our universal CAR T cell can eradicate the resulting tumors upon administration of the appropriate bispecific adapter. Taken together these results establish that a single anti-fluorescein CAR T cell can be exploited to eliminate antigenically heterogeneous tumors upon addition of the correct cocktail of ligand-fluorescein conjugates.

The Maudsley Daily Living Programme

This paper outlines a three-year controlled study, funded by the Department of Health and Social Security, which started at the Maudsley Hospital in October 1987. The research will compare seriously mentally ill patients maintained outside hospital on the daily living programme (DLP) with standard hospital-based care, and devise a multi-disciplinary training course in DLP for mental health care providers. It will be the first UK attempt at controlled replication of successful controlled studies from North America and Australia, and the first anywhere to devise systematic training in the approach.

Observations from community care for serious mental illness during a controlled study

A controlled study of community care in serious mental illness (SMI) was carried out. Patients with SMI were randomised to have hospital care or be looked after by a community psychiatric care team in a Daily Living Programme (DIP). The day-to-day work of a clinical team with the difficulties encountered in delivering community psychiatric care in an inner city is described. There were seven deaths from self-harm during the 45-month study. One DIP patient committed homicide. An ordeal by media following this and the suicides are described. Lessons learnt include the need for the community care team to be responsible for discharge from any in-patient phases and for attention to team morale, especially during adversity, and to time spent working under pressure.

Psychotherapy by computer

Aims and Method

Computerised self-help psychotherapies are fast becoming part of psychiatric practice. The aim of the study was to assess potential user preferences for the delivery of self-help psychotherapy for obsessive-compulsive disorder (OCD) and phobic anxiety disorders. A postal survey was undertaken of enquirers responding to a teletext article on self-help psychotherapies for OCD and agoraphobia. Subjects were asked their preferences for the delivery of self-help services for anxiety disorders, their acceptance or refusal of general practitioner (GP) referrals for such therapy, and how much they would be willing to pay for such a service.

Results

Of 326 questionnaires sent out 113 completed questionnaires were returned (35%). Twenty-seven per cent of respondents did not wish to access such services via their GP, 91% wanted access via a computer system and respondents were willing to pay an average of $10 per computer session (range 0–100).

Clinical Implications

Computerised self-help psychotherapies for OCD, phobic anxiety disorders and depression are becoming part of everyday clinical practice. This may be the first survey directly asking potential users about their preferred access to self-help psychotherapies for anxiety disorders. A significant proportion of responders did not wish to go via their GP to receive therapy and the vast majority welcomed therapy delivered by some form of computer system.

Community-oriented psychiatric care

The College is debating how to train psychiatrists for community care (CC) that is spreading – ahead of hard evidence of its value for certain problems in the UK. Much future psychiatry will be practised in the community outside hospital within multidisciplinary teams not always led by a psychiatrist, and wherein the lead-rôle changes frequently within a single meeting depending on whose expertise and readiness to accept responsibility emerge.

Problem severity in people using alternative therapies for anxiety difficulties

Aims and Method

The use of alternative therapies by people with mental health problems seems to be rising. Are the people who access alternative therapies those with mild or more severe problems? A postal survey was undertaken of enquirers responding to a teletext article on self-help psychotherapies for obsessive–compulsive disorder and agoraphobia. Respondents were asked to rate the severity and duration of their problem and the therapies and services they had used.

Results

Of 326 questionnaires sent out, 113 (35%) completed questionnaires were returned. Seventeen (15%) respondents had sought no help for their anxiety problems, 76 (67%) had been treated by their general practitioner (GP), 62 (55%) by a psychiatrist or psychologist and 48 (42%) had used alternative therapies. People who had sought help from their GP did not rate their problems significantly more severe than those who had not sought treatment. Those who had been treated by a psychiatrist or psychologist and those who had used alternative therapies rated their problem as being significantly more severe than those who had not sought help for it.

Clinical Implications

In this selected sample it was the more severe anxiety sufferers who had used alternative therapies.

Psychiatry in the future

A hundred and fifty years ago, physical disease was known to be widespread but was usually untreated. Anxiety and depression is now like that. Up to a fifth of the entire population are affected, of whom 84% were untreated in a UK community survey (Bebbington et al, 2000). ‘Developed’ countries are underdeveloped when it comes to treating anxiety and depressive disorders, even though effective treatment is available in the form of brief cognitive–behavioural therapy. In the UK, waiting times for such therapy can be as long as 2 years. Routine therapy outcomes are rarely reported. The delivery and monitoring and also teaching of therapy still largely conform to a 19th century model, and could be advanced by greater use of information technology. Such technology could catalyse a model of community care delivered mainly in the home, by enhancing access to effective self-help, audit of outcome and professional training.

Single-item screening for agoraphobic symptoms: validation of a web-based audiovisual screening instrument

The advent of web-based treatments for anxiety disorders creates a need for quick and valid online screening instruments, suitable for a range of social groups. This study validates a single-item multimedia screening instrument for agoraphobia, part of the Visual Screener for Common Mental Disorders (VS-CMD), and compares it with the text-based agoraphobia items of the PDSS-SR. The study concerned 85 subjects in an RCT of the effects of web-based therapy for panic symptoms. The VS-CMD item and items 4 and 5 of the PDSS-SR were validated by comparing scores to the outcomes of the CIDI diagnostic interview. Screening for agoraphobia was found moderately valid for both the multimedia item (sensitivity.81, specificity.66, AUC.734) and the text-based items (AUC.607–.697). Single-item multimedia screening for anxiety disorders should be further developed and tested in the general population and in patient, illiterate and immigrant samples.

Adult Recall of Having Been Bullied in Attenders of an Anxiety Disorder Unit and Attenders of a Dental Clinic: A Pilot Controlled Study

Little is known about the prevalence of having been bullied in adults with versus adults without an anxiety disorder, so a pilot comparison was undertaken. A questionnaire on recall of having been bullied was completed by 81 attenders of a behavioural psychotherapy unit for anxiety disorders and by 81 attenders of a dental clinic who had no psychiatric problems but who were similar to the anxiety disorder group in gender, marital and employment characteristics. Recall of being bullied was significantly more common in the anxiety disorder referrals than in the dental patients. Results warrant testing of whether being bullied as a child increases the likelihood of developing an anxiety disorder in later life, controlling for demographic, personality and ethnic variables.

The effectiveness of problem solving therapy in deprived South African communities: results from a pilot study

BACKGROUND

The majority of South Africans with a DSM-IV diagnosis receive no treatment for their mental health problems. There is a move to simplify treatment for common mental disorders (CMDs) in order to ease access. Brief problem solving therapy (PST) might fill the treatment gap for CMD's in deprived communities in South Africa. This pilot study evaluates the feasibility, acceptability and effectiveness of this PST program for CMD's in deprived communities around Cape Town.

METHODS

A Dutch problem solving program was adapted and translated into English, Xhosa and Afrikaans and thereafter implemented in townships around Cape Town. An initial attempt to recruit participants for online PST proved difficult, and so the program was adapted to a booklet format. Volunteers experiencing psychological distress were invited to participate in the either individually or group delivered 5-week during self-help program. To evaluate the effectiveness, psychological distress was administered through self-report questionnaires. After completion of the intervention participants also rated the program on various acceptability aspects.

RESULTS

Of 103 participants, 73 completed 5 weeks of brief PST in a booklet/workshop format. There were significantly more dropouts in those who used the booklet individually than in the group. Psychological distress measured on the K-10 and SRQ fell significantly and the program was evaluated positively.

CONCLUSIONS

The results suggest that brief problem solving in a booklet/workshop format may be an effective, feasible and acceptable short-term treatment for people with CMD's in deprived communities. In this setting, group delivery of PST had lower drop-out rates than individual delivery, and was more feasible and acceptable. Randomized controlled trials are needed to evaluate the effect of brief self-help PST more rigorously.

Quick and easy self-rating of Generalized Anxiety Disorder: validity of the Dutch web-based GAD-7, GAD-2 and GAD-SI

Screening of Generalized Anxiety Disorder (GAD), which is often undetected and untreated, could be improved by quick and easy web-based data collection. This paper aims to validate the web-based self-rated 7-item GAD-7, its shortened 2-item GAD-2 and a single item from the GAD-7 scale (GAD-SI) to screen for GAD. Of a total of 502 subjects aged 18-80 who rated the web-based GAD-7, Center for Epidemiological Studies Depression scale (CES-D) and Hospital Anxiety and Depression Scale (HADS), 157 (31%) subjects had a WHO Composite International Diagnostic Interview for DSM-IV-disorders by telephone. The GAD-7 had good reliability. Subjects with a GAD-diagnosis had significantly higher means on GAD-2, GAD-SI and GAD-7 than subjects without a GAD-diagnosis. The AUC (Area Under the Curve) of the GAD-SI and GAD-2 was accurate and not significantly different to the GAD-7 AUC. The web-based GAD-SI, GAD-2 and GAD-7 are reliable, valid tools to quickly screen for GAD in busy mental health settings and clinical research. More research is needed to validate the GAD-SI 'Do you have trouble relaxing' to see if its screening properties approach those of the GAD-7.

Brief self-rated screening for depression on the Internet

BACKGROUND

The Internet offers promising possibilities for the quick screening of depression for treatment and research purposes. This paper aims to validate three self-rated measures to screen for depression on the Internet: SID (single-item depression scale), CES-D (Center for Epidemiological Studies Depression scale) and K10 (Kessler psychological distress scale).

METHODS

Of the 502 subjects aged 18-80 who rated the SID, CES-D and K10 measures on the Internet, 157 (31%) subjects were also interviewed by telephone using the WHO Composite International Diagnostic Interview (C)IDI) for DSM-IV-disorders.

RESULTS

Cronbach's alpha for both web self-rated measures CES-D and K10 was 0.90. The SID correlated 0.68 (P<0.001) with the CES-D and with the K10. The CES-D correlated 0.84 with the K10 (P<0.001). Subjects with a DSM-IV diagnosis for any depressive disorder had significantly higher means (P<0.001) on the three self-rated measures for depressive symptoms than subjects without a diagnosis of any depressive disorder. Using any depressive disorder as the gold standard, the area under the curve (AUC) of the SID was 0.71 (95% CI: 0.63-0.79), which was significantly lower than the AUC of the CES-D (AUC: 0.84; 95% CI: 0.77-0.90, P=0.003) and of the K10 (AUC: 0.81; 95% CI: 0.73-0.88, P=0.0024). The AUCs for the K10 and CES-D did not differ significantly from each other.

LIMITATIONS

The CIDI interviews were not recorded, so inter-rater reliability could not be calculated.

CONCLUSIONS

The CES-D and K10 are reliable, valid tools for care providers to quickly screen depressive patients on the Internet and for researchers to collect data.

Social support moderates outcome in a randomized controlled trial of exposure therapy and (or) cognitive restructuring for chronic posttraumatic stress disorder

OBJECTIVE

To understand what predicts good outcome in psychiatric treatments, thus creating a pathway to improving efficacy.

METHOD

Our study investigated relations between predictor variables and outcome (on the Clinician Administered Posttraumatic Stress Disorder [PTSD] Scale [CAPS]) at posttreatment for 77 treatment completers in a randomized controlled trial of exposure therapy and (or) cognitive restructuring, compared with relaxation, for chronic PTSD in adults.

RESULTS

More social support on the Significant Others Scale significantly predicted better outcome on the CAPS, even after controlling for the effects of treatment group and of pretreatment severity. Importantly, social support was only a significant predictor of outcome for participants receiving cognitive restructuring and (or) exposure therapy and not for participants in the relaxation condition.

CONCLUSIONS

Better social support is associated with significantly greater gain following cognitive restructuring and (or) exposure therapy for PTSD. Future interventions should consider augmenting social support as an adjunct to treatment.

Implementation of Internet-based preventive interventions for depression and anxiety: role of support? The design of a randomized controlled trial

Background

Internet-based self-help is an effective preventive intervention for highly prevalent disorders, such as depression and anxiety. It is not clear, however, whether it is necessary to offer these interventions with professional support or if they work without any guidance. In case support is necessary, it is not clear which level of support is needed. This study examines whether an internet-based self-help intervention with a coach is more effective than the same intervention without a coach in terms of clinical outcomes, drop-out and economic costs. Moreover, we will investigate which level of support by a coach is more effective compared to other levels of support.

Methods

In this randomized controlled trial, a total of 500 subjects (18 year and older) from the general population with mild to moderate depression and/or anxiety will be assigned to one of five conditions: (1) web-based problem solving through the internet (self-examination therapy) without a coach; (2) the same as 1, but with the possibility to ask help from a coach on the initiative of the respondent (on demand, by email); (3) the same as 1, but with weekly scheduled contacts initiated by a coach (once per week, by email); (4) weekly scheduled contacts initiated by a coach, but no web-based intervention; (5) information only (through the internet). The interventions will consist of five weekly lessons. Primary outcome measures are symptoms of depression and anxiety. Secondary outcome measures are drop-out from the intervention, quality of life, and economic costs. Other secondary outcome measures that may predict outcome are also studied, e.g. client satisfaction and problem-solving skills. Measures are taken at baseline (pre-test), directly after the intervention (post-test, five weeks after baseline), 3 months later, and 12 months later. Analysis will be conducted on the intention-to-treat sample.

Discussion

This study aims to provide more insight into the clinical effectiveness, differences in drop-out rate and costs between interventions with and without support, and in particular different levels of support. This is important to know in relation to the dissemination of internet-based self-help interventions.

A brief Web-based screening questionnaire for common mental disorders: development and validation

BACKGROUND

The advent of Internet-based self-help systems for common mental disorders has generated a need for quick ways to triage would-be users to systems appropriate for their disorders. This need can be met by using brief online screening questionnaires, which can also be quickly used to screen patients prior to consultation with a GP.

OBJECTIVE

To test and enhance the validity of the Web Screening Questionnaire (WSQ) to screen for: depressive disorder, alcohol abuse/dependence, GAD, PTSD, social phobia, panic disorder, agoraphobia, specific phobia, and OCD.

METHODS

A total of 502 subjects (aged 18 - 80) answered the WSQ and 9 other questionnaires on the Internet. Of these 502, 157 were assessed for DSM-IV-disorders by phone in a WHO Composite International Diagnostic Interview with a CIDI-trained interviewer.

RESULTS

Positive WSQ "diagnosis" had significantly (P < .001) higher means on the corresponding validating questionnaire than negative WSQ "diagnosis". WSQ sensitivity was 0.72 - 1.00 and specificity was 0.44 - 0.77 after replacing three items (GAD, OCD, and panic) and adding one question for specific phobia. The Areas Under the Curve (AUCs) of the WSQ's items with scaled responses were comparable to AUCs of longer questionnaires.

CONCLUSIONS

The WSQ screens appropriately for common mental disorders. While the WSQ screens out negatives well, it also yields a high number of false positives.

Computer-aided psychological treatments: evolving issues

Evidence is growing that several computer-aided psychotherapy (CP) systems can effectively improve a range of common mental health problems. Most clients find CP acceptable because of its convenience, confidentiality, and reduction of stigma. CP can be accessed in a clinic, but recently clients have used CP especially on the Internet at home, with brief support on a telephone helpline and/or by email. Brief and efficient screening and support greatly reduce attrition. CP's efficacy, and encouragement of its dissemination and implementation by some national funding bodies and governmental agencies, has led to its spread as a regular care option and is increasing access to psychological therapies in some countries. Transfer of this new approach from use in tight research studies to use as an integrated part of everyday care under widely varying conditions generates teething problems that are being managed in diverse ways across different centers. Anonymized Internet audit of CP outcomes facilitates effective care and clinical governance. This review examines the current state of the art as well as the science and broad applications of CP.

Self-exposure treatment of recurrent nightmares: waiting-list-controlled trial and 4-year follow-up

BACKGROUND

In open and randomized controlled trials self-exposure therapy reduced the frequency of nightmares but follow-up ceased at 7 months post-entry.

METHOD

Ten adults who attended an outpatient clinic and had DSM-IV nightmare disorder were put on a 3-month waiting-list. After 3 months they were given a self-exposure manual and were asked to follow its instructions for 4 weeks and were then followed up for 4 years. They were rated at 0, 3, 4, 5, 7, 10, 16, 28 and 52 months. At month 0 only, a matched control group of 10 subjects from the same clinic who had no axis I or II disorder was also rated.

RESULTS

At month 0, the nightmare sufferers had more nightmares, anxiety, depression, hostility and somatic symptoms than the matched control group. All 10 nightmare sufferers completed the 3-month waiting-list, 4-week self-exposure therapy and 4-year follow-up without any dropouts. The recurrent nightmares and most associated symptoms did not improve while on the waiting-list but improved markedly after self-exposure therapy and remained improved over the 4-year follow-up.

CONCLUSIONS

Adults' recurrent nightmares and associated symptoms failed to improve over a 3-month waiting-list period but reduced greatly after subsequent self-exposure therapy with minimal therapist contact over 1 month, and these gains continued over the next 4 years.

Oral pimecrolimus in the treatment of moderate to severe chronic plaque-type psoriasis: a double-blind, multicentre, randomized, dose-finding trial

BACKGROUND

There is a need for safe and effective alternative treatments for patients with moderate to severe psoriasis.

OBJECTIVES

Pimecrolimus is a calcineurin inhibitor that is being investigated in oral form for the treatment of psoriasis.

PATIENTS AND METHODS

A double-blind, randomized, parallel-group, dose-finding study was performed. Healthy adult outpatients with moderate to severe chronic plaque-type psoriasis (n = 143) were randomized to receive oral placebo or pimecrolimus 10 mg, 20 mg or 30 mg twice daily (b.d.) for 12 weeks.

MAIN OUTCOME MEASURES

The Psoriasis Area and Severity Index (PASI) was used to assess clinical severity of psoriasis. Results were analysed at weeks 7 (primary endpoint) and 13. Safety was assessed by monitoring all adverse events, laboratory investigations (blood chemistry, urinalysis, haematology) and physical examinations.

RESULTS

The change from baseline in PASI at week 7 showed a dose-dependent effect. The differences between each of the two higher doses of pimecrolimus and placebo were statistically significant (P < 0.001; ANOVA). The mean percentage decreases from baseline in PASI in the placebo group and pimecrolimus 10 mg, 20 mg and 30 mg b.d. groups at week 7 were 3.1%, 22.2%, 51.3% and 54.0%, respectively. Most adverse events were of mild or moderate severity. The only adverse event to show a dose-response relationship was a transient feeling of warmth. No clinically relevant effects on laboratory parameters were observed, and no increase in skin infection with pimecrolimus was seen.

CONCLUSIONS

Oral pimecrolimus produces a dose-dependent reduction in psoriasis severity, with doses of 20 mg and 30 mg b.d. being the most effective and well tolerated.

Efficacy and tolerability of three different doses of oral pimecrolimus in the treatment of moderate to severe atopic dermatitis: a randomized controlled trial

BACKGROUND

Adult atopic dermatitis (AD) can seriously affect quality of life of patients and their families, and patients' disease is frequently not satisfactorily controlled with topical therapy. There is a need for alternatives to topical treatment in patients with moderate to severe AD.

OBJECTIVES

To investigate the efficacy and safety of oral pimecrolimus, and to determine the response to three different doses in the treatment of AD.

METHODS

In a double-blind, placebo-controlled, parallel-group, dose-finding study, patients with moderate to severe AD were randomized to receive either placebo, or oral pimecrolimus 10, 20 or 30 mg twice daily. The study consisted of a pretreatment phase, a 12-week double-blind treatment phase, and a 12-week post-treatment phase.

RESULTS

In total, 103 patients were randomized. A clear, dose-dependent therapeutic effect of pimecrolimus treatment was observed, with a statistically significant onset of efficacy at week 2 and the greatest reduction from baseline of the Eczema Area and Severity Index of 66.6% at week 7 in the 30 mg twice daily dose group. Oral pimecrolimus was well tolerated and there were no signs of nephrotoxicity or the induction of hypertension.

CONCLUSIONS

These data demonstrate the clinically relevant efficacy and short-term safety of oral pimecrolimus in adults with moderate to severe AD. Longer-term studies in larger cohorts are now required.

Brief scheduled phone support from a clinician to enhance computer-aided self-help for obsessive-compulsive disorder: Randomized controlled trial

Treatment-resistant obsessive-compulsive disorder (OCD) patients from around the United Kingdom who employed computer-guided self-help by using BTSteps over 17 weeks were randomized to have brief live phone support from a clinician either (1) in nine Scheduled clinician-initiated calls or (2) only in calls Requested by the patient (n=22 per condition). Call content and mean duration were similar across conditions. Scheduled-support patients dropped out significantly less often, did more homework of self-exposure and self-imposed ritual prevention (95% vs. 57%), and showed more improvement in OCD symptoms and disability. Mean total support time per patient over 17 weeks was 76 minutes for Scheduled and 16 minutes for Requested patients. Giving brief support proactively by phone enhanced OCD patients' completion of and improvement with computer-aided self-help.

Cost-effectiveness of computerised cognitive-behavioural therapy for anxiety and depression in primary care: randomised controlled trial

BACKGROUND

Cognitive-behavioural therapy (CBT) is effective for treating anxiety and depression in primary care, but there is a shortage of therapists. Computer-delivered treatment may be a viable alternative.

AIMS

To assess the cost-effectiveness of computer-delivered CBT.

METHOD

A sample of people with depression or anxiety were randomised to usual care (n=128) or computer-delivered CBT (n=146). Costs were available for 123 and 138 participants, respectively. Costs and depression scores were combined using the net benefit approach.

RESULTS

Service costs were 40 British pounds (90% CI - 28 British pounds to 148 British pounds) higher over 8 months for computer-delivered CBT. Lost-employment costs were 407 British pounds (90% CI 196 British pounds to 586 British pounds) less for this group. Valuing a 1-unit improvement on the Beck Depression Inventory at 40 British pounds, there is an 81% chance that computer-delivered CBT is cost-effective, and it revealed a highly competitive cost per quality-adjusted life year.

CONCLUSIONS

Computer-delivered CBT has a high probability of being cost-effective, even if a modest value is placed on unit improvements in depression.

Clinical efficacy of computerised cognitive-behavioural therapy for anxiety and depression in primary care: randomised controlled trial

BACKGROUND

Preliminary results have demonstrated the clinical efficacy of computerised cognitive-behavioural therapy (CBT) in the treatment of anxiety and depression in primary care.

AIMS

To determine, in an expanded sample, the dependence of the efficacy of this therapy upon clinical and demographic variables.

METHOD

A sample of 274 patients with anxiety and/or depression were randomly allocated to receive, with or without medication, computerised CBT or treatment as usual, with follow-up assessment at 6 months.

RESULTS

The computerised therapy improved depression, negative attributional style, work and social adjustment, without interaction with drug treatment, duration of preexisting illness or severity of existing illness. For anxiety and positive attributional style, treatment interacted with severity such that computerised therapy did better than usual treatment for more disturbed patients. Computerised therapy also led to greater satisfaction with treatment.

CONCLUSIONS

Computer-delivered CBT is a widely applicable treatment for anxiety and/or depression in general practice.

Computer-aided self-help for phobia/panic via internet at home: a pilot study

In an open study, ten people with phobia or panic disorder who could not travel repeatedly to a therapist accessed a computer-aided exposure self-help system (FearFighter) at home on the internet with brief therapist support by telephone. They improved significantly, and their outcome and satisfaction resembled those in patients with similar disorders who used FearFighter in clinics with brief face-to-face therapist support.

Computer-aided CBT self-help for anxiety and depressive disorders: Experience of a London clinic and future directions

This article describes a broad-spectrum, computer-aided self-help clinic that raised the throughput of anxious/depressed patients per clinician and lowered per-patient time with a clinician without impairing effectiveness. Many sufferers improved by using one of four computer-aided systems of cognitive behavior therapy (CBT) self-help for phobia/panic, depression, obsessive-compulsive disorder, and general anxiety. The systems are accessible at home, two by phone and two by the Web. Initial brief screening by a clinician can be done by phone, and if patients get stuck they can obtain brief live advice from a therapist on a phone helpline. Such clinician-extender systems offer hope for enhancing the convenience and confidentiality of guided self-help, reducing the per-patient cost of CBT, and lessening stigma. The case examples illustrate the clinical process and outcomes of the computer-aided system.

Routine monitoring of outcome over 11 years in a residential behavioural psychotherapy unit

BACKGROUND

Though research trials have to rate clinical outcome, few units monitor outcome of their routine care over many years. We report such monitoring to evaluate therapy over time and under changing operating and economic conditions.

METHOD

Clinical outcome data were collected routinely over 11 years in a behavioural psychotherapy unit whose residential patients mostly had severe, chronic obsessive-compulsive disorder (OCD) treated by self-exposure therapy. Data were from 218 referrals during 4 of the 11 available years.

RESULTS

In each of the 4 time periods, the patients improved consistently and highly significantly by 30-50% on symptoms and disability, which resembled outcome in a multi-centre controlled trial. There were almost no significant differences in pre-treatment ratings between patients who attended follow-up, patients who completed residential treatment but not follow-up and those who did not complete residential treatment. When the unit became a hostel and the UK government introduced an internal market, more chronic patients were admitted who often lived far away.

CONCLUSIONS

The fact that successive OCD cohorts had improved comparably by discharge suggests there was no 'burn-out' in staff standards of care over 11 years, and no loss of gains when the unit became a more cost-effective hostel.

Computerized, interactive, multimedia cognitive-behavioural program for anxiety and depression in general practice

BACKGROUND

Cognitive-behavioural therapy (CBT) brings about significant clinical improvement in anxiety and depression, but therapists are in short supply. We report the first phase of a randomized controlled trial of an interactive multimedia program of cognitive-behavioural techniques, Beating the Blues (BtB), in the treatment of patients in general practice with anxiety, depression or mixed anxiety/depression.

METHOD

One hundred and sixty-seven adults suffering from anxiety and/or depression and not receiving any form of psychological treatment or counselling were randomly allocated to receive, with or without medication, BtB or treatment as usual (TAU). Measures were taken on five occasions: prior to treatment, 2 months later, and at 1, 3 and 6 months follow-up using the Beck Depression Inventory, Beck Anxiety Inventory and Work and Social Adjustment Scale.

RESULTS

Patients who received BtB showed significantly greater improvement in depression and anxiety compared to TAU by the end of treatment (2 months) and to 6 months follow-up. Symptom reduction was paralleled by improvement in work and social adjustment. There were no interactions of BtB with concomitant pharmacotherapy or duration of illness, but evidence, on the Beck Anxiety Inventory only, of interaction with primary care practice. Importantly, there was no interaction between the effects of BtB and baseline severity of depression, from which we conclude that the effects of the computer program are independent of starting level of depression.

CONCLUSIONS

These results demonstrate that computerized interactive multimedia cognitive-behavioural techniques under minimal clinical supervision can bring about improvements in depression and anxiety, as well as in work and social adjustment, with and without pharmacotherapy and in patients with pre-treatment illness of durations greater or less than 6 months. Thus, our results indicate that wider dissemination of cognitive-behavioural techniques is possible for patients suffering from anxiety and/or depression.

Reducing demands on clinicians by offering computer-aided self-help for phobia/panic. Feasibility study

BACKGROUND

Many patients with phobia/panic find it hard to access effective treatment.

AIMS

To test the feasibility of computer-guided exposure therapy for phobia/panic.

METHOD

Self-referrals were screened for 20 min and, if suitable, had six sessions of computer-guided self-help (from a system called FearFighter). Pre- and post-treatment ratings of 54 patients were compared with those of 31 similar out-patients with phobia/panic who received the same treatment guided by a clinician.

RESULTS

At pre-treatment, computer-guided cases were slightly less severe than clinician-guided patients. In a post-treatment intent-to-treat analysis, both groups improved comparably but computer-guided patients spent 86% less time with a clinician than did purely clinician-guided patients, who had no access to the computer system.

CONCLUSIONS

Computer-guided self-exposure therapy appeared feasible and effective for self-referrals and saved much clinician time. A controlled study is now needed.

Family and past history of mental illness as predisposing factors in post-traumatic stress disorder

BACKGROUND

Family studies of post-traumatic stress disorder (PTSD) have given inconsistent results to date. Identifying predisposing factors in PTSD compared to anxiety disorders may help to clarify the classification of PTSD as a diagnostic entity.

METHOD

Retrospective case note study of 87 PTSD patients who participated in an RCT, and 51 PTSD patients and 87 agoraphobics treated routinely in outpatients.

RESULTS

Compared to agoraphobics, PTSD patients had significantly less family history of anxiety disorder but not mental illness in general. They also had significantly less personal history of mental illness prior to the index episode.

CONCLUSIONS

Trauma precipitated PTSD in subjects who had significantly fewer premorbid predisposing factors than did agoraphobics. Such factors may predispose agoraphobics to become psychiatrically ill after more minor trauma. Research is needed to systematically compare the events which precipitate PTSD as opposed to agoraphobia and other anxiety disorders.

Self-exposure therapy for panic disorder with agoraphobia: randomised controlled study of external v. interoceptive self-exposure

BACKGROUND

Exposure to external phobic cues is an effective therapy for panic/agoraphobia but the value of exposure to interoceptive cues is unclear.

AIMS

Randomised controlled comparison in panic/agoraphobia of the effects of (a) external, (b) interceptive or (c) combined external and interoceptive self-exposure to (d) control subjects.

METHOD

Eighty out-patients were randomised to a control group or to one of three forms of self-exposure treatment (external, interoceptive, or combined). Each treatment included seven sessions over 10 weeks and daily self-exposure homework. Assessments were at pre- and post-treatment and up to 1 year post-entry. Assessors remained blind during treatment.

RESULTS

The three self-exposure groups improved significantly and similarly at post-treatment and up to 1-year followup, and significantly more than did the control subjects. Rates of improvement on main outcome measures averaged 60% at post-treatment and 77% at follow-up.

CONCLUSIONS

The three methods of self-exposure were equally effective in reducing panic and agoraphobic symptoms in the short- and long-term.

Adult gender identity disorder can remit

A 4-year remission in a case of gender identity disorder (GID in DSM-IV, previously termed transsexualism) plus obsessive-compulsive disorder (OCD) prompted a search for further similar cases. Reports were reviewed for apparent remissions in adult GID. GID and paraphilias may wax and wane. This fluctuation can be in tandem with that of comorbid psychopathology or in response to sexual and other life events. Remission has been documented at up to 10 years. If evaluated over many years, GIDs and paraphilias can be less fixed than is often thought. The frequency of permanent remission may be underestimated, as such subjects may not consult clinicians. Implications for the clinician are that such subjects require a long trial period of cross-gender living prior to any surgical interventions.

Obsessive-compulsive disorder and delusions revisited

BACKGROUND

The concept of fixed, unshakeable (delusional) beliefs within the context of obsessive-compulsive disorder (OCD) is one that has received varying amounts of attention in the literature, and has not yet received universal acknowledgement. There are good grounds for including these cases within the diagnostic concepts of OCD, with significant implications for clinical management.

AIMS

To present cases with unusual OCD, in order to re-evaluate the issue of delusions and OCD.

METHOD

The cases of five subjects with delusions in the course of obsessive-compulsive disorder are presented to illustrate 'delusional' OCD. The management and outcome of these cases are discussed.

RESULTS

Fixity and bizarreness of beliefs in OCD occur on a continuum from 'none' to 'delusional intensity' and may fluctuate within subjects.

CONCLUSIONS

The idea that these cases may represent a form of OCD has implications for management, as, if this is correct, they should be able to respond to appropriate behavioural and/or pharmacological strategies used in OCD.

Phobic nature of social difficulty in facially disfigured people

BACKGROUND

Over 390,000 people in the UK are disfigured. Facial disfigurement distresses sufferers markedly but has been studied little.

AIMS

To compare fearful avoidance of people with a facial disfigurement with that of a group of patients with phobia.

METHOD

Comparison of Fear Questionnaire agoraphobia, social phobia and anxiety depression sub-scale scores of 112 facially disfigured people (who scored high on Fear Questionnaire problem severity in three survey studies) with those of 66 out-patients with agoraphobia and 68 out-patients with social phobia.

RESULTS

Facially disfigured people and patients with social phobia had similar Fear Questionnaire scores. In contrast, facially disfigured people scored lower on the agoraphobia sub-score but higher on the social phobia sub-score than did patients with agoraphobia.

CONCLUSIONS

Facially disfigured people with psychological difficulties resembled people with social phobia on Fear Questionnaire social phobia, agoraphobia and anxiety/depression sub-scores but were less agoraphobic and more socially phobic than were people with agoraphobia. Facially disfigured people thus appeared to be socially phobic and to deserve the cognitive--behavioural therapy that is effective for such phobias.
