Dietary habits in adult Japanese patients with vitiligo.

Vitiligo is an autoimmune skin disease with acquired depigmentation. Dietary habits may modulate the pathogenesis of vitiligo. We evaluated dietary habits in adult Japanese patients with nonsegmental vitiligo, and compared their results with those of age- and sex-matched controls. We also examined the relationship between dietary habits and Vitiligo Area Scoring Index (VASI), or vitiligo on different anatomical sites. The intakes of energy, nutrients, and foods in the participants were analyzed using a brief-type self-administered diet history questionnaire. Patients with vitiligo showed higher body mass index (BMI) and lower intakes of manganese, vitamin D, pulses, and confection, compared with controls. Multivariate logistic regression analysis showed that vitiligo was associated with high BMI. VASI was higher in males than in females, and negatively correlated with age or intakes of potatoes and vegetables other than green/yellow vegetables. Linear multivariate regression analysis showed that high VASI was associated with younger age. Multivariate logistic regression analysis showed that moderate to severe vitiligo (VASI ≥ 4.25) was associated with male sex and longer disease duration. Multivariate logistic regression analyses showed the following association with vitiligo on respective anatomical sites: high intake of eggs and dairy products and high VASI on the head or neck, high intake of oils and fats and high VASI on the trunk, high intake of cereals and high VASI on the upper limbs, male sex and high VASI on the lower limbs, and high BMI and high VASI on the hands or feet. In conclusion, the control of obesity might have prophylactic or therapeutic effects on vitiligo.

Clinical Impact of a Pharmacist-Driven Prospective Audit with Intervention and Feedback on the Treatment of Patients with Bloodstream Infection.

Evidence for the utility of pharmacist-driven antimicrobial stewardship programs remains limited. This study aimed to evaluate the usefulness of our institutional pharmacist-driven prospective audit with intervention and feedback (PAF) on the treatment of patients with bloodstream infections (BSIs). The effect of pharmacist-driven PAF was estimated using an interrupted time series analysis with a quasi-experimental design. The proportion of de-escalation during BSI treatment increased by 44% after the implementation of pharmacist-driven PAF (95% CI: 30−58, p < 0.01). The number of days of therapy decreased by 16 per 100 patient days for carbapenem (95% CI: −28 to −3.5, p = 0.012) and by 15 per 100 patient days for tazobactam/piperacillin (95% CI: −26 to −4.9, p < 0.01). Moreover, the proportion of inappropriate treatment in empirical and definitive therapy was significantly reduced after the implementation of pharmacist-driven PAF. Although 30-day mortality did not change, compliance with evidenced-based bundles in the BSI of Staphylococcus aureus significantly increased (p < 0.01). In conclusion, our pharmacist-driven PAF increased the proportion of de-escalation and decreased the use of broad-spectrum antibiotics, as well as the proportion of inappropriate treatment in patients with BSI. This indicates that pharmacist-driven PAF is useful in improving the quality of antimicrobial treatment and reducing broad-spectrum antimicrobial use in the management of patients with BSI.

Dietary habits in Japanese patients with palmoplantar pustulosis.

Palmoplantar pustulosis (PPP) is a chronic dermatitis characterized by sterile intra-epidermal pustules associated with erythema and scales on the palms and soles. Tumor necrosis factor (TNF)-α/interleukin (IL)-23/IL-17 inflammatory pathway may be involved in the pathogenesis of PPP, and the skin lesions manifest the enhanced expression of IL-8 in keratinocytes and increased levels of antimicrobial peptide cathelicidin, leucine leucine-37 in vesicles/pustules. Some PPP patients are associated with arthro-osteitis, called pustulotic arthro-osteitis (PAO). Dietary habits may modulate the pathogenesis of PPP, however, have not been investigated in PPP patients. We evaluated dietary habits in adult Japanese PPP patients, using a validated, brief-type self-administered diet history questionnaire, and compared their results to those of age- and sex-matched healthy controls. The results in PPP patients with PAO were compared to those in the patients without. Japanese PPP patients showed higher body mass indices (BMIs), higher intakes of pulses and sugar/sweeteners, and lower intake of vitamin A, compared to those of healthy controls. The bivariate and multivariable logistic regression analysis showed that PPP was associated with high BMI, high intake of pulses, and low intake of vitamin A. The sodium intake and BMI were positively correlated with palmoplantar pustulosis area and severity index (PPPASI). The linear multivariate regression analysis revealed that sodium intake and BMI were predictors of PPPASI. The age and sodium intake in the patients with PAO were lower than those in the patients without. The bivariate and multivariable logistic regression analysis showed that PAO was negatively associated with age and sodium intake. This is the first study showing the dietary habits in patients with PPP. Further studies should clarify if the dietary intervention to correct the BMI and sodium intake will alter the progress of PPP.

A combined analysis of data to identify predictive factors for spermatogenesis in men with hypogonadotropic hypogonadism treated with recombinant human follicle-stimulating hormone and human chorionic gonadotropin.

OBJECTIVE: To compare the efficacy and safety of recombinant human FSH (r-hFSH) and hCG treatment for male hypogonadotropic hypogonadism (HH) in different populations and to identify characteristics predictive of spermatogenesis. DESIGN: A combined analysis of data from four clinical trials. SETTING: Phase III, open-label, noncomparative studies with similar designs conducted in Australia, Europe, Japan, and the United States. PATIENT(S): One hundred men with complete idiopathic or acquired HH. INTERVENTION(S): Pretreatment with hCG for 3-6 months, followed by combination therapy with hCG and r-hFSH (150 IU three times weekly) for up to 18 months. Doses of r-hFSH were adjusted according to spermatozoa count until the maximum dose was reached. MAIN OUTCOME MEASURE(S): The primary efficacy endpoint was a spermatozoa concentration of >or=1.5 x 10(6)/mL. RESULT(S): A total of 81 men remained azoospermic but achieved normal serum T concentrations after hCG pretreatment. Of these, 68 (84.0%) achieved spermatogenesis and 56 (69.1%) achieved spermatozoa concentrations >or=1.5 x 10(6)/mL. Large baseline mean testicular volume, low body mass index, and advanced sexual maturity were predictors of good response to therapy. Similar treatment responses were observed across different study populations. CONCLUSION(S): R-hFSH (combined with hCG) is effective for the restoration of fertility in the majority of men with HH.
