Purpose: Valproic acid (VPA) is not only an antiepileptic drug but also a mood stabilizer for patients with bipolar disorder. Long-term VPA therapy can cause carnitine deficiency, which may result in an increase in the blood ammonia level, in patients with epilepsy. However, information about this effect in patients with bipolar disorder is limited. The aim of this study was to investigate the associations between the serum VPA level and the carnitine and ammonia levels in psychiatric adult patients with epilepsy. Methods: The subjects were 182 consecutive Japanese adult patients (mean age 54.3 ± 19.5 years) diagnosed with bipolar disorder and treated with VPA. The serum VPA level, carnitine fraction, and plasma ammonia level were measured. Furthermore, the free carnitine and acylcarnitine fractions were measured using an enzyme cycling method. Results: Sixty-nine patients (38%) had a low free carnitine level. There were significant differences in sex, height, VPA dose, serum VPA level, total carnitine level, acylcarnitine level, and acylcarnitine/free carnitine ratio between patients with a low free carnitine level and those with a normal range of free carnitine. The simple and multiple regression analyses revealed that the VPA dose and the serum VPA level were inversely and significantly correlated with the free carnitine level. The plasma ammonia level was correlated with the VPA dose, serum VPA level, and acylcarnitine level but not with the free carnitine level. Conclusions: These findings suggest that carnitine deficiency is associated with the VPA dose and the serum VPA level in patients with bipolar disorder. However, it is unlikely that carnitine deficiency is associated with hyperammonemia in patients with bipolar disorder.

ObjectivesTo determine whether etiological beliefs are different among schizophrenia patients, their family, and medical staff.Patients and methodsA cross-sectional study was performed at five hospitals and one mental clinic and included 212 patients, 144 family members, and 347 medical staff other than psychiatrists. A questionnaire about the possible etiological causes of schizophrenia was used.ResultsThere were significant differences in response scores among the three groups on using Angermeyer’s and Goulding’s classifications. Factor analyses revealed the following four subscales: Psychosocial, Biological, Environmental, and Cultural connotations. The structure varied among patients, family, and medical staff.ConclusionThe perspectives of schizophrenia etiology were different among patients, family, and medical staff.

We describe herein a case of severe relapsed pyoderma gangrenosum (PG) concomitantly with severe pouchitis treated by tacrolimus. A 25-year-old woman had undergone proctocolectomy with construction of ileo-anal pouch surgery for refractory ulcerative colitis (UC). She first developed PG with refractory pouchitis, and infliximab (IFX) was administered to induce remission due to resistance to glucocorticoid therapy. After achieving remission, IFX was stopped. Five years later, severe skin ulcers concomitantly with severe pouchitis recurred and treatment with 30 mg oral prednisolone (PSL) combined with topical tacrolimus showed partial improvement. When PSL was tapered to 15 mg, the skin ulcers and diarrhea aggravated. Endoscopy revealed multiple ulcers in the ileal pouch. Treatment with oral tacrolimus was initiated for severe pouchitis and refractory PG. Forty days later, all skin ulcers became scars and multiple ulcers in the ileal pouch were also improved. Our case suggests that oral tacrolimus treatment could be a valuable treatment option for UC patients with refractory PG and pouchitis.

ObjectivesDelirium signifies underlying brain dysfunction; however, its clinical significance in hemodialysis remains unclear. In this study, we sought to determine whether the occurrence of delirium during hemodialysis was associated with higher mortality.Patients and methodsThis was a retrospective, 10-year cohort study. This study was performed at the urology department located within a hospital in Oyokyo, Hirosaki. We analyzed 338 of 751 patients who underwent hemodialysis. Psychiatrists diagnosed patients with delirium according to the corresponding DSM-IV-TR criteria. Cox proportional hazard regression, which was adjusted for patient age at the time of hemodialysis initiation, sex, and the presence of diabetes mellitus, was performed. Hazard ratios (HRs) and their 95% CIs were also reported.ResultsIn total, 286 patients without psychiatric diseases and 52 patients with delirium were evaluated. Eighty percent of patients with delirium died within 1 year of hemodialysis initiation, while only 22% of patients without delirium died within the same time period (P<0.01). Kaplan–Meier plots demonstrated the existence of associations between delirium and all-cause mortality (global log-rank P<0.001), cardiovascular disease-related mortality (global log-rank P<0.001), and infection-related mortality (global log-rank P<0.001). Moreover, Cox proportional hazard regression showed that delirium was associated with all-cause mortality (HR=1.96, 95% CI: 1.32–2.90), cardiovascular disease-related mortality (HR=2.65, 95% CI: 1.31–5.35), and infection-related mortality (HR=3.30, 95% CI: 1.34–8.10).ConclusionDelirium is an independent predictor of death in patients undergoing hemodialysis.
