Development of the Pharmacist's Stress Scale for Home Care (PSS) and evaluation of its reliability and validity

BACKGROUND

As the needs for home care increase, contact with patients and jobs out of the pharmacy such as the patients' homes have increased, and there is concern that the situation increases pharmacists' work-related stress. Stress deteriorates pharmacists' quality of life (QOL) and affects the quality of services they provide. In this study, we developed a scale for the measurement of stress of pharmacists engaged in home care and evaluated it in pharmacists in 3 prefectures of the Tokai district, Japan.

METHODS

Based on the stress factors of pharmacists in home care extracted by previous studies, a 59-item questionnaire was developed. The questionnaires were sent to 1785 pharmacies engaged in home care in 3 prefectures of the Tokai district, and anonymous responses were obtained from 399 (valid response rate: 22.4%). The answers to each question were scored using 5-point scale (1: I feel no stress to 5: I always feel strong stress).

RESULTS

As a result of factor analysis, the Pharmacist's Stress Scale for Home Care (PSS) was prepared with 51 items, i.e., 14 related to the first factor, "difficulty and feeling of incompetence in patient care", 9 related to the second factor, "relationship with superiors and work environment", 13 related to the third factor, "burdens related to work load and work contents", 10 related to the fourth factor, "communication with patients and families", and 5 related to the fifth factor, "communication with other professions". Cronbach's α coefficients for the entire scale and each factor were ≥ 0.833, and sufficient internal consistency was obtained.

CONCLUSIONS

The scale developed in this study is considered to be useful for the measurement of stress of pharmacists derived from interpersonal work and home care services. Leaving the job and burnout are expected to be prevented by perceiving the stress level of the pharmacists by themselves using this scale and coping with stress.

Long-term outcomes of delayed clozapine initiation in treatment-resistant schizophrenia: a multicenter retrospective cohort study

BACKGROUND

Clozapine is the only antipsychotic medication with proven efficacy against treatment-resistant schizophrenia. This multicenter retrospective cohort study aimed to evaluate the impact of a delay in clozapine initiation on long-term outcomes.

METHODS

Patients who initiated clozapine treatment between July 2009 and December 2018 were included in this study. According to the length of time from the diagnosis of schizophrenia to clozapine initiation, the patients were categorized into one of three groups: early (≤ 9 years), intermediate (10-19 years), and late (≥ 20 years) initiation. The endpoints were psychiatric rehospitalization and all-cause clozapine discontinuation within 3 years. Hazard ratios (HR) and 95% confidence interval (CI) were estimated using the Fine and Gray method or the Cox proportional hazards model.

RESULTS

The incidence rates of rehospitalization within three years, according to the cumulative incidence function, were 32.3% for early, 29.7% for intermediate, and 62.2% for late initiation, respectively. Late initiation had a significantly higher risk of psychiatric rehospitalization than early initiation (HR, 2.94; 95% CI, 1.01- 8.55; P = 0.016 by the Gray's test). The risk of psychiatric rehospitalization was not significantly different between the early and intermediate initiation groups. The incidence rate of all-cause clozapine discontinuation within three years using the Kaplan-Meier method was 13.0% for early, 10.6% for intermediate, and 20.1% for late initiation. The risk of all-cause clozapine discontinuation was not significantly among the groups. The late initiation group had more patients discontinuing because of death due to physical diseases than the other groups.

CONCLUSIONS

The study suggests that clozapine should be initiated promptly in patients with treatment-resistant schizophrenia to prevent psychiatric rehospitalization during long-term treatment. Further prospective studies with appropriate consideration of confounding factors and large sample sizes are needed to strengthen the evidence.

Subjective assessment of brexpiprazole in patients with schizophrenia: a prospective observational study

OBJECTIVES

To investigate the subjective assessments of an antipsychotic treatment with brexpiprazole.

METHODS

This was a 14-week prospective observational study. Nineteen patients participated in the study between February 2019 and January 2020.

RESULTS

Patients had a mean age of 40.6±14.2 years and a Clinical Global Impressions-Severity of Illness scale (CGI-S) score of 4.6±1.2 at the initiation of brexpiprazole treatment. The Subjective Well-being under Neuroleptic drug treatment Short form, Japanese version (SWNS-J) total score significantly improved from 68.1±22.3 in week 2 to 79.5±21.0 in week 14 (p=0.0084). The SWNS-J subscales of self-control and social integration status also significantly improved from 14.0±4.7 and 13.9±6.0 in week 2 to 17.0±4.7 and 16.0±5.1 in week 14, respectively (p=0.0053 and 0.012, respectively). No significant improvements were observed in any other SWNS-J subscales or the Drug Attitude Inventory-10 (DAI-10) in the 14-week observation period. Moreover, the SWNS-J total score did not correlate with the DAI-10 (r=0.31, p=0.19), or CGI-S (r=-0.18, p=0.47) scores.

CONCLUSIONS

The present results suggest that brexpiprazole might improve subjective well-being, although this may not necessarily reflect psychopathological improvements. To enhance medication adherence, it is important to perform subjective assessments on patients over time.

Polypharmacy Management of Antipsychotics in Patients with Schizophrenia

Schizophrenia is a chronic psychiatric disease that is characterized by psychotic symptoms, including positive, negative, affective, and aggressive symptoms, as well as cognitive dysfunction, and is primarily treated using drug therapy, the continuation of which is essential to prevent recurrence/recrudescence. Various second-generation antipsychotics with pharmacological properties or adverse events that differ from those of conventional antipsychotics have recently been introduced, and pharmaceutical management is required for drug efficacy assessments and adverse event monitoring/management of these drugs. Antipsychotic monotherapy (APM) is the gold standard treatment for schizophrenia and is recommended in various guidelines. However, a subgroup of patients with schizophrenia do not or only partially respond to APM. Therefore, antipsychotic polypharmacy (APP), in which ≥2 antipsychotics are combined, has been routinely utilized to compensate for insufficient responses to APM in clinical practice. APP has recently been proposed as an evidence-based treatment option, but does not consider clinicians' experience. However, the risk of APP-related adverse events is high. The application of APP needs to be carefully reviewed, whilst taking into consideration patient backgrounds. Furthermore, the risk of APP-related adverse events is higher in elderly patients than in the general population; therefore, caution is needed. This review discusses the merits of APP, matters that need to be considered, and a switch from APP to APM, and also focuses on the application of APP in clinical practice.

Students' perception of a hybrid interprofessional education course in a clinical diabetes setting: a qualitative study

OBJECTIVES

To explore what the student participants learned and how they felt about the use of three educational settings, namely, face-to-face workshop setting, asynchronous and synchronous online learning environments and interactions with outpatients in a real-world clinical setting in a hybrid interprofessional education course.

METHODS

This qualitative study used semi-structured in-depth interviews with healthcare undergraduate student participants in a course comprising workshops in three educational settings. A total of 15 healthcare undergraduate students, which included four medical, three pharmacy, five nursing and three nutrition students, completed this IPE course. All students agreed to participate in the study. We conducted four focus groups selected using convenient sampling. Focus group transcripts were analysed using the 'Steps for Coding and Theorization' qualitative data analysis method. We investigated the students' perception through the experience of three educational settings in the hybrid interprofessional education course.

RESULTS

The students recognised that this course had three types of educational spaces, namely, real, semi-real and unreal. Then, the positive changes in the awareness of students are trained in recognition of the patient perspective, the recognition of the roles discharged by the other professions and the recognition of the functions of their own profession after experiencing the educational spaces designated for this course.

CONCLUSIONS

The repeated experience of participants to real, semi-real and unreal educational spaces promoted changes over time in the students' awareness of interprofessional competencies with respect to patient-centred care and ameliorated their readiness to undertake interprofessional tasks.

Usefulness of a psychomotor function test as a cognitive function scale for patients with schizophrenia: A pilot study

As cognitive dysfunction due to schizophrenia is strongly associated with patients' social rehabilitation, cognitive functions have been examined as a therapeutic target. Although the Brief Assessment of Cognition in Schizophrenia (BACS) has been used to evaluate cognitive function, it is difficult to administer in routine clinical practice due to its time-consuming nature. Therefore, a novel tool is needed to facilitate the assessment of cognitive function. In the present study, we examined whether cognitive function can be assessed effectively by testing psychomotor function in patients with schizophrenia. Test batteries consisting of choice reaction time (CRT) and compensatory tracking task (CTT) and the BACS were examined in 20 schizophrenic patients to evaluate the correlation between the scales by Pearson correlation coefficient. Of the test batteries, the CRT was significantly correlated with attention functions, a subtest of the BACS (r = -0.506, p = 0.023), and the CTT was strongly correlated with attention functions (r = -0.716, p < 0.001) and working memory (r = -0.633, p = 0.003). A multiple regression analysis was performed to clarify the association between psychomotor function tests and the total BACS score, and peripheral awareness task, a component of CTT, was independently associated with the total BACS score (β = -0.59, p = 0.004) with an R2 of 0.37. Thus, of the psychomotor function tests, the CRT and the CTT are highly useful in assessing cognitive functions in schizophrenic patients. However, no having large sample size in this study is a limitation.

Trend survey on adverse event profiles of antipsychotic long-acting injections and oral agents using the Japanese adverse drug event report database

This study aims to assess the differences in adverse event profiles of long-acting injectable antipsychotics (LAIs) and oral antipsychotics (OAPs) using real-world data in the Japanese Adverse Drug Event Report database. Reporting odds ratios were determined using disproportionality analysis to estimate the risk of adverse events for LAIs and OAPs. Differences in adverse event profiles between formulations were determined after propensity score matching. Time-to-onset of adverse events was compared between LAIs and OAPs using the Weibull shape parameter. Signals were detected for approximately 50% of the adverse events (12 of 22) with LAIs and for the majority of adverse events (19 of 22) with OAPs. LAIs was associated with significantly lower reporting rate than OAPs for extrapyramidal symptom, neuroleptic malignant syndrome, and dystonia. For QT prolongation, convulsions, and hyperglycemia associated with LAIs, the 95% Confidence Interval of β included 1 in time-to-onset analysis. Real-world data suggest that LAIs tend to reduce the occurrence of extrapyramidal symptom and neuroleptic malignant syndrome, but a number of other adverse events have potential risks as well as OAPs. In addition, onset of adverse events with LAIs have been shown to be slightly delayed, requiring more careful long-term monitoring.

Acceptance of the Deltoid Muscle Injection of Aripiprazole Long-acting Injectable in the Patients with Schizophrenia

Objective

To improve poor medication adherence in schizophrenic patients, long-acting injectable (LAI) antipsychotics are used. However, it has not yet become common in Japan. Recently, aripiprazole LAI was approved for alternative injection into the deltoid muscle in addition to the gluteal muscle. The acceptance for the proposal to switch from gluteal to deltoid injections of aripiprazole LAI was investigated.

Methods

The subjects were 32 outpatients with schizophrenia who had continuously received aripiprazole LAI administration into the gluteal muscle for ≥ 6 months. In the patients who had continued deltoid injection for 3 months after switching, the changes in the pain and shame in comparison with gluteal injections were evaluated.

Results

Switching to the deltoid injection was chosen by 17 out of 32 patients. Three months later, 9 patients were still receiving deltoid injections with highly rated satisfaction. The main reasons for switching to deltoid injections included the pain and shame associated with gluteal injections. The main reason for returning to the gluteal injection was the pain experienced from the injection in the deltoid.

Conclusion

The option to select the injected area was based on the amount of pain in the deltoid and gluteal sites, leading to the widespread use of aripiprazole LAI.

Effectiveness in Switching from Antipsychotic Polypharmacy to Monotherapy in Patients with Schizophrenia: A Case Series

In Japan, drug therapy for schizophrenia is characterized by high-dose antipsychotic polypharmacy, which is an uncommon approach internationally. In this study, we reduced the number of antipsychotic agents in 5 patients using the Safety Correction of High-dose Antipsychotic Polypharmacy (SCAP) method and conducted a survey regarding treatment satisfaction. The switch from polypharmacy to monotherapy was achieved in all patients. There was no deterioration in psychiatric symptoms, and adverse reactions were reduced. Three of the subjects were satisfied with the decrease in the number of antipsychotic agents and dose-reduction. These results suggest that the SCAP method is a safe and useful method that can be applied in a clinical setting.

Relationship between peer evaluation and interprofessional self-evaluation in a joint healthcare team-based learning class involving three universities

OBJECTIVE

This study aimed to clarify the relationship between interprofessional self-evaluation and peer evaluation during interprofessional education (IPE) using team-based learning (TBL). We also aimed to clarify differences in interprofessional cooperation between students with high and low peer evaluation scores.

METHODS

In total, 483 students (grades 3-5) from nine faculties at three universities participated in a TBL-based IPE program. The students completed five interprofessional self-evaluation domains (the modified Tsukuba IPE model) before and after IPE. Students also completed peer evaluation after IPE. Students were divided into three groups by peer evaluation scores (low, middle, high), and the post-class self-evaluation scores of these groups were compared using a Kruskal-Wallis test. Multiple regression analysis was also performed. Peer evaluation comments were analyzed using a qualitative inductive method.

RESULTS

Students in the low peer evaluation group had significantly lower scores in the "Regarding participation in group work" domain than students in the high group (P<0.05). Students in the high group received positive comments, such as [good communication] and [working cooperatively], whereas students in the low group were required to improve in two areas: [speaking up more] and [need more communication].

CONCLUSIONS

There was a significant relationship between peer evaluation by team members and self-evaluation for "Regarding participation in group work." Students with high peer evaluation scores participated with active attitudes, whereas students with low scores were considered passive. This study suggested that using peer evaluation may enhance students' professional cooperation by improving their communication and attitudes toward active participation.

The effects of different periods of co-administration of oral and long-acting injectable aripiprazole: A propensity score analysis

OBJECTIVE

Long-acting injectable (LAI) aripiprazole is recommended to be combined with oral aripiprazole for 2 weeks after its introduction. However, we often experience patients who require more than 2 weeks of combined use. Therefore, differences in combination periods need to be examined.

METHODS

This was a case-control study. We surveyed prescription profiles for oral aripiprazole administration in conjunction with LAI aripiprazole introduction and assessed the clinical course during a 12-week follow-up period.

RESULTS

Among 121 patients, 58 (47.9%) were administered both oral and LAI aripiprazole for more than 2 weeks. Although there was no significant difference in treatment failure (defined as psychiatric hospitalization or discontinuation of LAI aripiprazole from any cause) between the two groups, the group that was administered oral aripiprazole for more than 2 weeks received less additional benzodiazepines compared with that of the 2 weeks group (adjusted odds ratio, 0.055; 95% confidence interval [0.0060, 0.50]; p < 0.01).

CONCLUSIONS

Our data support a flexible co-administration period for oral and LAI aripiprazole in consideration of the pharmacokinetics, but further studies are needed.

An internet-based survey in Japan concerning social distance and stigmatization toward the mentally ill among doctors, nurses, pharmacists, and the general public

Stigma associated with psychiatric disorders tends to be manifested as negative attitudes or behavior toward the mentally ill. It has negative influences, such as leading to difficulty in establishing trust-based relationships and interfering with medical treatment. In order to reduce such stigma, it is necessary to clarify its extent and characteristics in healthcare professionals. Considering this, an Internet-based questionnaire survey was conducted, involving doctors (n = 186), nurses (n = 161), and pharmacists (n = 192) in comparison with the general public (n = 331), and using the Whatley Social Distance Scale (WSDS) and Index of Attitudes toward the Mentally Ill (IATM) as stigma-related indices. Median total WSDS scores and interquartile range were as follows: doctors: 15.5(12.0-18.0), nurses: 14.0(12.0-16.5), pharmacists: 15.0(13.0-17.0), and the general public: 16.0(13.0-18.0). Similarly, median IATM scores were as follows: doctors: 39.0(36.0-42.0), nurses: 39.0(37.0-43.0), pharmacists: 40.0(36.0-42.0), and the general public: 37.0(33.0-41.0). IATM scores were significantly higher in the professional groups than the general public group. Both healthcare professionals and the general public with prior exposure to mental illness were more favorable attitudes toward the mentally ill. Especially among healthcare professionals, they working in psychiatric departments were more favorable attitudes. These results suggest that the stigma of healthcare professionals toward the mentally ill was shown to have a smaller and relatively favorable attitude than that of the general public. In order to correct the stigma it was suggested that a good contact experience with the patient such as work and training in psychiatry is effective.

Assessment of Switching to Suvorexant versus the Use of Add-on Suvorexant in Combination with Benzodiazepine Receptor Agonists in Insomnia Patients: A Retrospective Study

Objective

Suvorexant is a novel hypnotic drug that does not interact with the conventional γ-aminobutyric acid (GABA)-A receptor. We investigated the method by which suvorexant was introduced in insomnia patients who were taking benzodiazepine receptor agonists (BzRA).

Methods

This was a retrospective study. We extracted clinical data for patients who were prescribed suvorexant and were already using BzRA. The patients were assigned to two groups, the switching and add-on groups. We assessed the suvorexant discontinuation rate at one month after the prescription of the drug.

Results

One hundred and nineteen patients were assigned to the switching group, and 109 were assigned to the add-on group. The add-on group exhibited a significantly higher all-cause discontinuation rate than the switching group (odds ratio, 2.7; 95% confidence interval, 1.5 to 5.0; adjusted p<0.001). Intolerability was a significantly stronger risk factor for suvorexant discontinuation in the add-on group (22.0% vs. 7.6%, p<0.002), and the most common adverse effect was oversedation.

Conclusion

Our results show that the add-on of suvorexant increases the frequency of oversedation compared with switching in insomnia patients that are taking BzRA. However, this was only a preliminary retrospective study, and further studies will be required to confirm our findings.

Diagnostic Usefulness of APRI and FIB-4 for the Prediction of Liver Fibrosis After Liver Transplantation in Patients Infected with Hepatitis C Virus

BACKGROUND

Aspartate transaminase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) are well known as representative indirect serum biomarkers related to liver fibrosis. The usefulness of these markers for the diagnosis of liver fibrosis after liver transplantation (LT) in hepatitis C virus (HCV)-infected patients and the influence of splenectomy were investigated.

METHODS

From June 2003 to May 2014, 31 HCV-infected patients who underwent LT and postoperative follow-up liver biopsies were included in this study. The association between liver fibrosis and serum biomarkers and the influence of splenectomy on APRI and FIB-4 were also investigated.

RESULTS

A total of 195 biopsy specimens were collected, and liver fibrosis was identified as: F0, 59.7%; F1, 34.1%; and F2, 6.3%. Both APRI and FIB-4 were significantly higher in patients who showed F1 and F2 in liver biopsy specimen than F0 (P values, .009 and .022, respectively); sensitivity and specificity of APRI were, respectively, 63.4% and 66.7%, and those of FIB-4 were 57.7% and 69.6%. In 11 patients (35.5%) who underwent splenectomy at the time of LT, the cutoff values for APRI and FIB-4 were 0.61 and 1.41, which were significantly lower than the corresponding values (1.00 and 3.64) of patients without splenectomy.

CONCLUSIONS

APRI and FIB-4 could effectively estimate liver fibrosis after LT for HCV-related liver disease. For LT patients with splenectomy, APRI and FIB-4 were also useful to estimate liver fibrosis, but the standard values should be adjusted lower than those for patients without splenectomy.

Effectiveness of the repeated administration of scopolamine ointment on clozapine-induced hypersalivation in patients with treatment-resistant schizophrenia: A preliminary study

INTRODUCTION

This study investigated the efficacy of scopolamine (an anticholinergic agent) ointment against clozapine-induced hypersalivation.

METHODS

The patients enrolled in this study consisted of 10 clozapine-treated schizophrenia patients and 10 healthy adult men. A prospective, randomized, double-blind, crossover, placebo-controlled clinical trial was designed.

RESULTS

A total of 10 patients and 10 healthy adult men completed the study. No significant reduction in the saliva production of the clozapine-treated patients was observed; however, that of the healthy adult men decreased significantly.

DISCUSSION

Scopolamine ointment was not effective against clozapine-induced hypersalivation. A further study is necessary for confirming its effect.

Usefulness of Interprofessional Education (Tsurumai-Meijo IPE) in Program Collaborating with Simulated Patients

Collaboration with multiple healthcare professionals is important to provide safer and higher quality care. Interprofessional education (IPE) promotes the practice of team-based care. The establishment of Tsurumai-Meijo IPE, including interprofessional education and practice (IPEP) and video-teaching materials, was conducted in collaboration with school of medicine/nursing in Nagoya University and Fujita Health University, because Meijo University does not have its own clinical settings and faculties except for pharmacy. In the established Tsurumai-Meijo IPE, pharmacy, medicine, and nursing students interviewed simulated patients (SP) together or separately and practiced team-based care through Tsurumai-Meijo IPEP. Students could learn in advance and on their own about each professional's knowledge related to patient care by using video-teaching materials from the Meijo IPE homepage. Using a questionnaire survey at the end of program, this study was examined whether Tsurumai-Meijo IPEP, and video-teaching materials were useful for understanding importance of team-based care. More than 83% of students indicated that Tsurumai-Meijo IPE is useful on future clinical practice. This suggests that the program and materials are beneficial to the medical student education. In the optional survey of some clinical pharmacists, who had participated in Tsurumai-Meijo IPE before graduation, they utilized it in their work and it facilitated their work related to team-based care. Tsurumai-Meijo IPE collaborating with SP is likely to contribute to provide high quality and safe team-based care by taking advantage of specialized professional ability of healthcare professionals.

Successful Blood Transfusion Management of a Living Donor Liver Transplant Recipient in the Presence of Anti-Jra: A Case Report

A 48-year-old Japanese woman was diagnosed with Budd-Chiari syndrome and transferred for possible living donor liver transplantation (LDLT). Examinations before LDLT revealed that the recipient had anti-Jr^a and preformed donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA). Rituximab was administrated at 16 days prior to the patient's scheduled LDLT for the prophylaxis of antibody-mediated rejection by DSA. The clinical significance of anti-Jr^a has not been clearly established because of the rarity of this antibody, so we discussed blood transfusion strategy with the Department of Blood Transfusion Service and prepared for Jr^a-negative packed red blood cells (RBCs). Intraoperative blood salvage was used during LDLT procedures to reduce the use of packed RBCs. Although post-transplantation graft function was excellent, a total of 44 U of Jr^a-negative RBCs were transfused during the entire perioperative period. Because sufficient amounts of Jr^a-negative packed RBCs were supplied, Jr^a mismatched blood transfusion was avoided. The patient was discharged from our hospital on postoperative day 102 without clinical evidence of any blood transfusion-related adverse events. Although there are some controversies of blood transfusion related to anti-Jr^a antibodies, the current strategies of blood transfusion for liver transplantation with anti-Jr^a are as follows: (1) sufficient supply and transfusion of Jr^a-negative matched packed RBCs and (2) application of intraoperative blood salvage to reduce the total amount of rare blood type RBCs. These strategies may be changed when the mechanism of anti-Jr^a alloimmunization is fully understood in the future.

Assessment of the Latent Adverse Events of Antipsychotic Treatment Using a Subjective Questionnaire in Japanese Patients with Schizophrenia

Objective

The adverse effects of antipsychotic agents can have a marked influence on medication adherence. In this study, we investigated the adverse events of antipsychotics that are less likely to be reported by patients and the reasons why such symptoms remain latent.

Methods

Data were collected by interviewing patients using a subjective questionnaire, and the associations between unreported symptoms and background factors were investigated.

Results

A total of 306 patients with schizophrenia or schizoaffective disorder were examined. Their major symptoms were daytime sleepiness (50.0%), weight gain (42.2%), and sexual dysfunction (38.9%). Sexual dysfunction was nominal significantly more common among the patients that had been treated with antipsychotic agent polypharmacy (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.07 to 4.30), and was nominal significantly more common among outpatients (OR, 1.78; 95% CI, 1.02 to 3.13). Only approximately 30% of the patients had reported their symptoms to their physicians.

Conclusion

Patients receiving antipsychotic treatment tolerate some symptoms and do not feel able to report them to their physicians. The most common reason for this is an insufficient patient-physician relationship. Sexual dysfunction is especially hard to identify because it is a delicate problem, and our findings demonstrate that subjective questionnaires are helpful for detecting such symptoms.

Effects of communication skill training (CST) based on SPIKES for insurance-covered pharmacy pharmacists to interact with simulated cancer patients

Background

With the development of pharmacotherapy and radiotherapy, cancer treatment is being shifted from surgical to outpatient services, consequently increasing insurance-covered pharmacies’ frequency of dealing with cancer patients. As the psychology of these patients is complex, it is necessary for pharmacists to educate them in consideration of their cognitive/medical and psychosocial aspects. This study analyzed cancer patient management by pharmacists working in such pharmacies and their communication skills before and after communication skill training based on SPIKES, a six-step protocol for delivering bad news, to confirm the usefulness of such training.

Methods

The study involved 20 pharmacists working in insurance-covered pharmacies within Aichi Prefecture. Before and after communication skill training, role-play sessions were held using standardized patients, whose levels of satisfaction were subsequently measured. Patient management by the pharmacists was analyzed using the Roter Interaction Analysis System as a method to analyze dialogues.

Results

The rate of each category, representing the pharmacists’ conversation styles when dealing with the patients, changed after communication skill training as follows: [Giving information]: decreased from 37.0 to 27.6%; [Empathy statements]: increased from 12.0 to 17.2%; and [Data gathering]: increased from 18.0 to 23.3%. The increase was particularly marked in: [Acceptance], accepting patients’ emotions and events in line with [Empathy statements]; [Promoting dialogues] as a sub-category of [Building a relationship]; and [Checks for understanding] as a sub-category of [Data gathering]. Furthermore, the results of pharmacist assessment by the patients, including their levels of overall satisfaction, showed significant correlations with [Empathy statements] and [Building a relationship].

Conclusions

Communication skill training may be effective to improve pharmacists’ conversation styles to listen to patients more attentively, accept their emotions, and provide education in accordance with their needs, rather than unilaterally providing information.

Trial registration

The study was approved by the Ethical Review Board of Meijo University as a research activity involving humans (approval number: H26-1).

Changes in Muscle Strength and Six-Minute Walk Distance Before and After Living Donor Liver Transplantation

BACKGROUND

Impaired exercise capacity and muscle weakness are important characteristics of liver transplantation recipients. Perioperative rehabilitation has been introduced to promote early mobilization of patients and to prevent postoperative pulmonary complications. However, it is unknown how physical status recovers during the hospital stay after a liver transplant. The purpose of this study was to evaluate the changes in clinical indicators that represent the functional exercise capacity and muscle strength before and after living donor liver transplantation (LDLT).

METHODS

We retrospectively reviewed 21 consecutive patients who underwent LDLT with perioperative rehabilitation from April 2014 to December 2015. Twelve patients who were tested for 6-minute walk distance, hand-grip strength, and isometric knee extensor muscle strength before and 4 weeks after LDLT were enrolled.

RESULTS

At the preoperative baseline, the 6-minute walk distance significantly correlated with the Model for End-stage Liver Disease score and pulmonary functions (vital capacity, forced vital capacity, and forced expiratory volume in 1 second of predictive values). Comparisons between the preoperative and postoperative values revealed significant decreases in weight, Barthel Index, hand-grip strength, and isometric knee extensor muscle strength. Changes in hand-grip strength and isometric knee extensor muscle strength after LDLT correlated with the preoperative Model for End-stage Liver Disease score.

CONCLUSIONS

Physical functional status had not been fully recovered 4 weeks after LDLT. Further investigation regarding developing a strategy for prevention of muscle atrophy before LDLT and recovery of physical fitness after LDLT would be helpful.

A Questionnaire-based Study of the Views of Schizophrenia Patients and Psychiatric Healthcare Professionals in Japan about the Side Effects of Clozapine

Objective

It is well documented that clozapine treatment causes agranulocytosis, but it can also induce drowsiness, constipation, and hypersalivation; however, these symptoms are usually less severe. It has been reported that clozapine-treated patients with schizophrenia and psychiatric healthcare professionals consider different side effects to be important. The aim of this study was to assess current practice related to the side effects of clozapine in clozapine-treated patients with schizophrenia and psychiatric healthcare professionals in Japan.

Methods

Data were collected from January 2014 to August 2015 in Okehazama Hospital, Kakamigahara Hospital, and Numazu Chuo Hospital. Clozapine-treated patients with schizophrenia and psychiatric healthcare professionals (psychiatrists and pharmacists) were enrolled in this study.

Results

Of the 106 patients and 120 psychiatric healthcare professionals screened, 100 patients and 104 healthcare professionals were included in this study. We asked the patients what side effects caused them trouble and we asked psychiatric healthcare professionals what side effects caused them concern. The patients and psychiatrists held similarly positive views regarding the efficacy of clozapine. The healthcare professionals were concerned about agranulocytosis (92.4%), blood routines (61.3%). On the other hand, the patients experienced hypersalivation (76.0%), sleepiness (51.0%). A positive correlation (R=0.696) was found between patient satisfaction and DAI-10 score.

Conclusion

Patients experienced more problems than healthcare professionals expected. However, usage experience of clozapine healthcare professionals tended to have similar results to patients. It is necessary that all healthcare professionals fully understand the efficacy and potential side effects of clozapine. This is very important for promoting clozapine treatment in Japan.

Postoperative Psychiatric Complications in Living Liver Donors

BACKGROUND

To understand the impact of psychologic variables on donor quality of life, we studied long-term data on postoperative psychiatric complications in living liver donors. This study is a focused psychological investigation of diagnoses, treatments, and long-term clinical courses of living liver donors with psychiatric complications.

METHODS

Of the 142 donors who underwent live-donor liver transplantation at Nagoya University Hospital between April 2004 and July 2014, we investigated those without a history of mental illness who had developed such illness after transplantation and required psychiatric treatment.

RESULTS

A total of 6 (4.2%) donors developed the following psychiatric complications after transplantation: major depressive disorder (n = 2), panic disorder (n = 2), conversion disorder (n = 1), and substance use disorder (n = 1). Concerning psychiatric treatment, all donors received antianxiety drugs, 3 took antidepressants, and supportive psychiatric therapy was concomitantly provided to all subjects. The average treatment period was 53.3 months. Regarding subject outcomes, 3 donors achieved remission, and the other 3 continued treatment. All subjects showed improvement in Global Assessment of Functioning Scale.

CONCLUSION

It is important to accurately diagnose postoperative psychiatric complications and provide long-term treatment in close coordination with transplant surgeons.

Vitamin E reduces liver stiffness in nonalcoholic fatty liver disease

AIM: To evaluate the efficacy of vitamin E treatment on liver stiffness in nonalcoholic fatty liver disease (NAFLD).

METHODS: Thirty-eight NAFLD patients were administered vitamin E for > 1 year. The doses of vitamin E were 150, 300, or 600 mg; three times per day after each meal. Responses were assessed by liver enzyme levels [aspartate aminotransferase (AST), alanine aminotranferease (ALT), and γ-glutamyl transpeptidase (γ-GTP)], noninvasive scoring systems of hepatic fibrosis-4 [FIB-4 index and aspartate aminotransferase-to-platelet index (APRI)], and liver stiffness [velocity of shear wave (Vs)] measured by acoustic radiation force impulse elastography. Vs measurements were performed at baseline and 12 mo after baseline. The patients were genotyped for the patatin-like phospholipase domain containing 3 (PNPLA3) polymorphisms and then divided into either the CC/CG or GG group to examine each group’s responses to vitamin E treatment.

RESULTS: We found marked differences in the platelet count, serum albumin levels, alkaline phosphatase levels, FIB-4 index, APRI, and Vs at baseline depending on the PNPLA3 polymorphism. AST, ALT, and γ-GTP levels (all P < 0.001); FIB-4 index (P = 0.035); APRI (P < 0.001); and Vs (P < 0.001) significantly decreased from baseline to 12 mo in the analysis of all patients. In the subset analyses of PNPLA3 genotypes, AST levels (P = 0.011), ALT levels (P < 0.001), γ-GTP levels (P = 0.005), APRI (P = 0.036), and Vs (P = 0.029) in genotype GG patients significantly improved, and AST and ALT levels (both P < 0.001), γ-GTP levels (P = 0.003), FIB-4 index (P = 0.017), and APRI (P < 0.001) in genotype CC/CG patients.

CONCLUSION: One year of vitamin E treatment improved noninvasive fibrosis scores and liver stiffness in NAFLD patients. The responses were similar between different PNPLA3 genotypes.

Effects of Prescription Drug Reduction on Quality of Life in Community-Dwelling Patients with Dementia

Purpose: Due to the use of multiple drugs and prevalence of diminished cognitive function, community-dwelling elderly individuals are more likely to have drug-related issues. We examined changes in quality of life (QOL) and activities of daily living (ADL) 3 months and 6 months after reducing drug use of dementia patients who had newly begun community-dwelling care.  Methods: Prescription drug use was reduced in the intervention group, whereas the non-intervention group continued their regimen or began using additional drugs. QOL and ADL were assessed with the Japanese version of the EQ-5D and the Barthel Index, respectively.  Results: Subjects were 32 individuals aged ≥65 years who had begun community-dwelling between March and July 2014 and had received approval for long-term care insurance. On average, the intervention group (n = 19) stopped using 2.6 prescription drugs. After 6 months, the differences in the QOL and ADL scores in the intervention group were -0.03 ± 0.29 and 6.32 ± 18.6, respectively, while the differences in the QOL and ADL scores in the non-intervention group (n = 13) were -0.13 ± 0.29 and -2.69 ± 23.7, respectively. In the intervention group, ADL scores were significantly increased by 14.0 ± 11.1 6 months after reduced benzodiazepine use.  Conclusions: QOL was maintained with reduced drug use, while ADL score was slightly increased. In addition, the reduction of benzodiazepine use significantly increased ADL. In order to reduce polypharmacy among community-dwelling elderly patients, it is necessary to create an opportunity for pharmacists to re-examine their prescriptions This article is open to POST-PUBLICATION REVIEW.

Effect of Adenine on Clozapine-induced Neutropenia in Patients with Schizophrenia: A Preliminary Study

Objective

This study examined the utility of adenine for preventing clozapine-induced neutropenia.

Methods

This retrospective study examined the effect of adenine on clozapine-induced neutropenia in patients with treatment-resistant schizophrenia and was conducted at Okehazama Hospital in Japan from July 2010 to June 2013. Adenine was available for use from June 2011 onwards. Twenty-one patients started receiving clozapine treatment from July 2010 to April 2011 (the pre-adenine adoption group), and 47 patients started receiving it from May 2011 to June 2013 (the post-adenine adoption group). The effects of adenine were assessed based on changes in the patients’ leukocyte counts and the frequency of treatment discontinuation due to clozapine-induced neutropenia.

Results

Sixty-eight patients were treated with clozapine from July 2010 to June 2013. Of the 21 patients in the pre-adenine adoption group, 4 discontinued treatment due to clozapine-induced neutropenia, whereas only 2 of the 47 patients in the post-adenine adoption group discontinued treatment. The frequency of treatment discontinuation due to clozapine-induced neutropenia was significantly lower in post-adenine adoption group than in the pre-adenine adoption group (p=0.047).

Conclusion

Adenine decreased the frequency of treatment discontinuation due to clozapine-induced neutropenia. Our data suggest that combined treatment with clozapine and adenine is a safe and effective strategy against treatment-resistant schizophrenia.

Comparison of the Effects of a Brand-name Drug and Its Generic Drug on the Quality of Life of Alzheimer's Disease Patients

Objective

The pharmacological effects of generic (GE) donepezil are the same as Aricept, its brand-name counterpart. However, little is known as to whether these two drugs provide the same quality of life (QOL). The study subjects were patients with Alzheimer’s disease who were taking donepezil hydrochloride tablets, and were selected by visiting either the local pharmacies or the patients’ homes. We chose the brand-name drug Aricept and its GE form donepezil to investigate, from a long-term caregiver’s perspective, the influence of both drugs on the patients’ QOL.

Methods

An EuroQol-5 Dimension (EQ-5D) was used to assess the QOL of patients with Alzheimer’s disease, before and after various Aricept and/or donepezil regimens. Patients were divided into four groups: first time users of Aricept (n=43), first time users of GE donepezil (n=45), users refilling previous prescriptions of Aricept (n=51), and users switching from Aricept to GE donepezil (n=51).

Results

The average change in the EQ-5D utility indices rose significantly in the patients starting a new regimen of Aricept and its GE drug. The patients continuing an existing regimen of Aricept showed no significant differences, even after Aricept was switched to a GE drug.

Conclusion

The QOL of patients starting a new regimen of Aricept and its GE drug improved. The QOL was maintained upon switching to the GE drug form.

Effect of Scopolamine Butylbromide on Clozapine-induced Hypersalivation in Schizophrenic Patients: A Case Series

Clozapine has been demonstrated to be useful for treating refractory schizophrenia. However, hypersalivation occurs in 31.0–97.4% of the patients treated with clozapine. Accordingly, some patients who are disturbed by their hypersalivation refuse to continue with clozapine treatment. This study investigated the efficacy of the anticholinergic agent scopolamine butylbromide against clozapine-induced hypersalivation. Five schizophrenia patients were coadministered scopolamine butylbromide (30–60 mg/day) for 4 weeks. At the baseline and after 4 weeks’ treatment, we subjectively evaluated hypersalivation using a visual analog scale and objectively assessed it using the Drooling Severity Scale and Drooling Frequency Scale. As a result, improvements in the patients’ Drooling Severity Scale and Drooling Frequency Scale scores, but no improvements in their visual analog scale scores, were observed after scopolamine butylbromide treatment. These results indicate that at least some schizophrenic patients with clozapine-induced hypersalivation would benefit from scopolamine butylbromide treatment. We conclude that clozapine-induced hypersalivation is one factor of stress to patients. Subjective hypersalivation was not improved, but objective hypersalivation was, by scopolamine butylbromide treatment. However, scopolamine butylbromide and clozapine possess anticholinergic effects so clinicians should closely monitor patients who take scopolamine butylbromide.

Living donor liver transplantation using a right liver graft with additional vein reconstructions for patient with situs inversus

Living donor liver transplantation (LDLT) using a right liver graft with additional vein reconstructions has not been previously reported in a situs inversus (SI) patient. A 60-year-old man with SI was referred for LDLT for end-stage cirrhosis secondary to hepatitis B. The calculated regional volumes of the individual hepatic vein territories in the right liver graft suggested that the middle hepatic vein (MHV) tributaries and the inferior right hepatic veins (IRHVs) should be reconstructed in addition to the right hepatic vein (RHV). On the back-table, the recipient's recanalized umbilical vein graft was anastomosed to the V5 opening, and the other side of vein graft was anastomosed to the RHV and V8 opening to create a large single orifice. After total hepatectomy, the right liver graft was placed in the left subphrenic space at the reversed position. The common orifice of hepatic venous drainage from RHV, V8 and V5 was anastomosed to the anatomical RHV conduit of the recipient, followed by IRHV anastomosis to the inferior vena cava. Postoperative course was almost uneventful, and no vascular complications were experienced. Even for SI patients, LDLT using a right liver graft with reconstructions of the MHV tributaries and the IRHVs is feasible.

Lipopolysaccharide of Aggregatibacter actinomycetemcomitans up-regulates inflammatory cytokines, prostaglandin E2 synthesis and osteoclast formation in interleukin-1 receptor antagonist-deficient mice

BACKGROUND AND OBJECTIVE

The interleukin (IL)-1 receptor antagonist (Ra) binds to IL-1 receptors and inhibits IL-1 activity. However, it is unclear whether the IL-1Ra plays a protective role in periodontal disease. The purpose of this study was to compare IL-1Ra knockout (KO) and wild-type (WT) mice in regard to proinflammatory cytokine production, osteoclast formation and bone resorption in response to periodontal bacterial lipopolysaccharide (LPS).

MATERIAL AND METHODS

Peritoneal macrophages (Mφs) were obtained from 13-wk-old IL-1Ra KO and WT mice. Peritoneal Mφs were cultured with or without 10 μg/mL of Aggregatibacter actinomycetemcomitans LPS for 24 h. The levels of IL-1alpha (IL-1α), IL-1beta (IL-1β), tumor necrosis factor-α (TNF-α) and IL-6 were measured in periotoneal Mφs supernatant fluid (PM-SF) using an ELISA. Bone marrow cells were obtained from the mice and stimulated with PM-SF for 9 d, then stained with TRAP. The frequency of TRAP-positive multinucleated giant cell formation was calculated based on a fusion index. PM-SF-stimulated calvarial bone resorption was analyzed using micro-computed tomography, and calvarial histological analysis was performed using hematoxylin and eosin and TRAP staining. The expression of cyclooxygenase-2 (Cox2), prostanoid receptor EP4 (Ep4) and Rank mRNAs in bone marrow cells were measured using real-time quantitative PCR, while prostaglandin E2 (PGE2 ) production was determined by ELISA.

RESULTS

The levels of IL-1α, IL-1β, TNF-α and IL-6 in IL-1Ra KO mice PM-SF stimulated with A. actinomycetemcomitans LPS were significantly increased by approximately 4- (p < 0.05), 5- (p < 0.05), 1.3- (p < 0.05) and 6- (p < 0.05) fold, respectively, compared with the levels in WT mice. Moreover, osteoclast formation, expression of Rank, Ep4 and Cox2 mRNAs and production of PGE2 were significantly increased by approximately 2- (p < 0.05), 1.6- (p < 0.05), 2.5- (p < 0.05), 1.6- (p < 0.05) and 1.9- (p < 0.05) fold, respectively, in IL-1Ra KO mice stimulated with A. actinomycetemcomitans LPS compared with WT mice.

CONCLUSION

IL-1Ra regulates IL-1 activity and appears to reduce the levels of other inflammatory cytokines, including TNF-α and IL-6, while it also reduces expression of the EP4 receptor related to prostanoid sensitivity and osteoclast formation. These results suggest that IL-1Ra is an important molecule for inhibition of inflammatory periodontal bone resorption.

Placental extract improves hippocampal neuronal loss and fear memory impairment resulting from chronic restraint stress in ovariectomized mice

We have recently found that combination of ovariectomy (OVX) and chronic restraint stress causes cognitive dysfunction and reduces hippocampal CA3 neurons in female rats and mice and that estrogen replacement and chronic treatment with Ginkgo biloba extract EGb 761 suppress the OVX/stress-induced behavioral and morphological changes. In this study, we examined the effect of placental extract on the memory impairment and neuromorphological change in OVX/stress-subjected mice. Female Slc:ICR strain mice were randomly divided into four groups: vehicle-treated OVX, porcine placental extract (120 and 2160 mg/kg)-treated OVX, and sham-operated control groups. Two weeks after surgical operation, OVX mice underwent restraint stress for 21 days (6 h/day), and all animals were then subjected to a contextual fear conditioning test followed by morphological examination by Nissl staining. Placental extract was orally administered once daily until the behavioral analysis was carried out. Chronic treatment with both doses of placental extract improved the OVX/stress-induced fear memory impairment and Nissl-positive cell loss of the hippocampal CA3 region, although it did not affect the loss of bone mineral density and increase in body weight after OVX. These results have important implications for the neuroprotective and cognition-enhancing effects of placental extract in postmenopausal women.

Effects of single therapeutic doses of promethazine, fexofenadine and olopatadine on psychomotor function and histamine-induced wheal- and flare-responses: a randomized double-blind, placebo-controlled study in healthy volunteers

Since most first-generation antihistamines have undesirable sedative effects on the central nervous systems (CNS), newer (second-generation) antihistamines have been developed to improve patients’ quality of life. However, there are few reports that directly compare the antihistaminic efficacy and impairment of psychomotor functions. We designed a double-blind, placebo controlled, crossover study to concurrently compare the clinical effectiveness of promethazine, a first-generation antihistamine, and fexofenadine and olopatadine, second-generation antihistamines, by measuring their potency as peripheral inhibitors of histamine-induced wheal and flare. Further, we investigated their sedative effects on the CNS using a battery of psychomotor tests. When single therapeutic doses of fexofenadine (60 mg), olopatadine (5 mg) and promethazine (25 mg) were given in a double-blind manner to 24 healthy volunteers, all antihistamines produced a significant reduction in the wheal and flare responses induced by histamine. In the comparison among antihistamines, olopatadine showed a rapid inhibitory effect compared with fexofenadine and promethazine, and had a potent effect compared with promethazine. In a battery of psychomotor assessments using critical flicker fusion, choice reaction time, compensatory tracking, rapid visual information processing and a line analogue rating scale as a subjective assessment of sedation, promethazine significantly impaired psychomotor function. Fexofenadine and olopatadine had no significant effect in any of the psychomotor tests. Promethazine, fexofenadine and olopatadine did not affect behavioral activity, as measured by wrist actigraphy. These results suggest that olopatadine at a therapeutic dose has greater antihistaminergic activity than promethazine, and olopatadine and fexofenadine did not cause cognitive or psychomotor impairment.

Therapeutic potential of nicotine for methamphetamine-induced impairment of sensorimotor gating: involvement of pallidotegmental neurons

INTRODUCTION

We have previously found that a disruption to prepulse inhibiton (PPI) induced by methamphetamine (METH) is associated with impaired functioning of pallidotegmental neurons, which play a crucial role in PPI of the startle reflex, through the activation of gamma-aminobutyric acid type B receptors in pedunculopontine tegmental neurons in mice.

OBJECTIVES

Here, we examined the effect of nicotine on METH-induced impairment of PPI of the startle reflex focusing on dysfunctional pallidotegmental neurons and the neural system.

RESULTS

Nicotine (0.15-0.5 mg/kg) ameliorated the deficit in PPI induced by acute METH, and the ameliorating effect of nicotine was antagonized by nicotinic receptor antagonists such as methyllycaconitine and dihydro-beta-erythroidine. The acute METH-induced disruption of PPI was accompanied by suppression of c-Fos expression in the lateral globus pallidus (LGP) as well as its induction in the caudal pontine reticular nucleus (PnC) in mice subjected to the PPI test. Nicotine-induced amelioration of PPI deficits in METH-treated mice was accompanied by a reversal of the changes in c-Fos expression in both the LGP and PnC to the basal level.

CONCLUSIONS

Nicotine is effective in ameliorating the impairment of PPI caused by METH, which may be associated with normalization of the pallidotegmental neurons.

A phase II trial of erlotinib monotherapy in pretreated patients (pts) with non-small cell lung cancer (NSCLC) who do not possess active EGFR mutations

8067

Background: Efficacy of gefitinib therapy strongly depends on the presence of active EGFR mutations in Asian NSCLC pts, with objective response rates (ORR) of 71.2% and only 1.1% in active mutant-positive (EGFRmt+) and -negative (EGFRmt-) tumors, respectively [Mok T, ESMO2008]. Recently, the survival advantage of erlotinib, another TKI, is observed even in pts with EGFRmt- tumors (HR=0.74, p=0.09 [Zhu C, JCO2008]), indicating such subpopulation might also benefit from this TKI. The aim of this trial was to evaluate its efficacy and toxicity in Japanese pts with relapsedEGFRmt- tumors. Methods: Primary endpoint was ORR. Patients with EGFRmt--NSCLC previously treated with one to three chemotherapy regimens were enrolled in this trial. The mutation status was assessed by the PCR clamp methods. Erlotinib was administered at a dose of 150mg/day until disease progression or unacceptable toxicities. Results: Thirty pts were enrolled between Jan and Dec 2008. Median duration of erlotinib treatment was 60 days. All pts were assessable for efficacy and safety. Demographics of the pts were as follows: M/F:24/6, Ad/others:20/10, ECOG-PS 0/1/2:7/19/4, and smoker/non-smoker:22/8. Platinum-based regimens were commonly used as the prior chemotherapy. Objective response was obtained in one pt (3.3%; RECIST). Seventeen pts obtained SD (56.7%). Toxicity profiles were almost tolerable with the treatment interruption in 11 pts (median duration; 10 days). Skin rash was common (grades 1, 2 and 3 in 7, 15, and 7 pts, respectively; NCI-CTCAE ver3). One pt developed grade 4 pulmonary embolism, but it seemed due to disease progression. Other 2 pts developed interstitial lung disease (grades 2 and 3 in one pt each). No treatment-related deaths (TRD) occurred. With a median follow-up time of 6.4 months, MST and MPFS time were 8.6 and 2.1 months, respectively. Conclusions: This is a first prospective biomarker study showing that erlotinib therapy for pretreated pts with EGFRmt- tumors seems as almost effective and safe as the standard docetaxel therapy (PR: 5.8%, SD: 42.7%, MST: 7.0 months, MTTP: 2.5 months and TRD: 4.9% [Shepherd JCO2000]).

Mild hepatic macrovesicular steatosis may be a risk factor for hyperbilirubinaemia in living liver donors following right hepatectomy

Background

The aim of this study was to evaluate the effects of mild macrovesicular steatosis on the outcome of living liver donors following right hepatectomy.

Methods

The medical records of 46 living liver donors who underwent right hepatectomy were studied. Ten donors had mild macrovesicular steatosis (5–10 per cent in seven and 11–20 per cent in three patients). Five donors with other liver pathology were excluded. Outcome in these ten donors (group 1) was compared with that in the remaining 31 donors with normal liver histology (group 2).

Results

The median duration until normalization of total bilirubin levels was 14 and 5 days in groups 1 and 2 respectively (P = 0·028). The peak total bilirubin level was significantly higher in group 1 than in group 2 (80·4 versus 49·6 µmol/l; P = 0·033). Multivariable analysis showed mild macrovesicular steatosis to be an independent risk factor for hyperbilirubinaemia (odds ratio 7·94 (95 per cent confidence interval 1·17 to 54·03); P = 0·034).

Conclusion

Mild macrovesicular steatosis may be related to adverse outcome in living liver donors who undergo right hepatectomy and, in terms of donor safety, is of potential concern in donor selection.

Simultaneous monitoring by real-time polymerase chain reaction of epstein-barr virus, human cytomegalovirus, and human herpesvirus-6 in juvenile and adult liver transplant recipients

Cytomegalovirus (CMV), Epstein-Barr virus (EBV), and human herpesvirus-6 (HHV-6) cause symptomatic diseases in liver transplant recipients. The loads of these viruses, the associations between viral DNAemia, serologic status, and acute rejection reactions were investigated in a group of 17 juvenile and 17 adult recipients of living donor liver transplantation (LDLT) for a median of 8 weeks posttransplantation. At least 1 plasma sample from 15/34 (44.1%) patients was positive for CMV DNA. For most of the CMV-positive patients, the CMV DNA appeared in the second week of LDLT, and disappeared by the eighth week. A minimum of 200 EBV DNA copies/mug peripheral blood mononuclear cell DNA (defined as positive for EBV) was detected in 5/34 (14.7%) patients, and the number of EBV-positive children was significantly greater than the number of EBV-positive adults. In most of the EBV-positive patients, the EBV loads increased after 4 weeks posttransplantation. Plasma HHV-6 was detected in 7/34 (20.6%) patients. HHV-6 DNA appeared for a short period from the second week of LDLT. In addition, 8 of the 19 virus-positive recipients carried 2 viruses, with the combination of CMV and HHV-6 being the most frequent. Serologic status seemed to be an important factor for all 3 viral infections. The rate of acute cellular rejection was not significantly higher in the CMV-, EBV-, or HHV-6-positive groups. Simultaneous monitoring for 3 herpesviruses revealed the impact of these viruses on LDLT recipients.
