TAC has been shown to be a potent immunosuppressive agent for solid organ transplantation in pediatrics. Neurotoxicity is a potentially serious toxic effect. It is characterized by encephalopathy, headaches, seizures, or neurological deficits. Here, we describe an eight-and-a-half-yr-old male renal transplant recipient with right BN. MRI demonstrated hyperintense T2 signals in the cervical cord and right brachial plexus roots indicative of both myelitis and right brachial plexitis. Symptoms persisted for three months despite TAC dose reduction, administration of IVIG and four doses of methylprednisolone pulse therapy. Improvement and eventually full recovery only occurred after TAC was completely discontinued and successfully replaced by everolimus.

Fluconazole-FK506 or fluconazole-cyclosporine drug combinations were tested in an ex vivo Trichophyton mentagrophytes human skin infection model. Conidia colonization was monitored by scanning electron microscopy over a 7-day treatment period. The fluconazole-FK506 combination demonstrated the most obvious advantage over single-drug therapy by clearing conidia and protecting skin from damage at low drug concentrations.

The aim of our study was to assess the association between FKBP5 gene polymorphisms and treatment response in patients with mood disorders using a meta-analysis. Eight separate studies that included data from 2199 subjects were identified. Meta-analysis was performed for three FKBP5 gene polymorphisms (rs1360780, rs3800373, and rs4713916). A significant association of FKBP5 gene rs4713916 polymorphism and response rate was found in patients with mood disorders (Overall: A versus G: OR=1.28, 95%CI=1.06-1.53, P=0.01; GA+AA versus GG: OR=1.32, 95%CI=1.05-1.67, P=0.02. Caucasian: A versus G: OR=1.28, 95%CI=1.06-1.55, P=0.01; GA+AA versus GG: OR=1.33, 95%CI=1.04-1.70, P=0.02). However, we did not detect the association between FKBP5 gene rs1360780 and rs3800373 polymorphisms and treatment response in patients with mood disorders (P>0.05). This meta-analysis demonstrates that treatment response in patients with mood disorders is associated with FKBP5 gene rs4713916 polymorphism, but not rs1360780 and rs3800373.
Vitiligo is an acquired loss of pigmentation and its treatment remains very difficult up to date. Narrow band ultraviolet B (NB-UVB) and topical immunomodulators are included among the most innovative approaches to vitiligo. We evaluated the efficacy and tolerability of NB-UVB, topical pimecrolimus and tacrolimus in the treatment of vitiligo. Adult patients with chronic and stable vitiligo refractory to conventional therapies were enrolled in an open parallel groups study. The patients were scheduled on the basis of a computer-generated randomization into three groups: 13 patients received NB-UVB phototherapy 3 times a week, 15 patients were treated with pimecrolimus 1% cream b.i.d. and 16 patients applied tacrolimus 0.1% ointment b.i.d. All three treatment regimens were performed for 24 weeks. At baseline and every three weeks for the whole period of therapy the patients were examined through digital photographs and, at the end of the study, based on the percentage of repigmentation, treatment outcome was classified as "absent" (0), "slight" (< 25%), mild (25-49%), "moderate" (50-74%), and "excellent" (> 75%). During the whole period of the study, possible side effects were recorded. The response to treatments varied according to the anatomical location of the lesions. No statistically significant differences in repigmentation for any anatomical site were recorded with the three treatments. The best results were obtained for lesions of the face with pimecrolimus cream and tacrolimus ointment and of the neck with NB-UVB. Statistically significant differences in repigmentation between photo-exposed and covered skin areas were recorded although the patients were asked to avoid direct UV exposition and to apply a very high protection sun screen on vitiligo lesions. All three treatments should be considered as a good option in the treatment of vitiligo. NB-UVB irradiation may represent the optimal choice in generalized vitiligo with topical immunomodulators in localized vitiligo.

Mean strength of the abdominal wall increased significantly over time in all groups (p<0.0001). Both the breaking strength and the bursting pressure of the ileum and colon anastomoses followed the same pattern. No differences were observed between control and experimental groups. In addition, no consistent differences were found between groups regarding wound hydroxyproline content and the activities of matrix metalloproteinase-2 and -9.

Tacrolimus is established as immunosuppressant after kidney transplantation. Polymorphism of the cytochrome P450 3A5 (CYP3A5) gene contributes significantly to tacrolimus dose requirements. Recently, CYP3A4*22 was reported to additionally affect tacrolimus pharmacokinetics (PK). In addition, there are further polymorphic genes, possibly influencing CYP3A activity [pregnane x receptor NR1I2, P450 oxidoreductase (POR), and peroxisome proliferator-activator receptor alpha (PPARA)]. We aimed to investigate combined effects of these gene variants on tacrolimus maintenance dose and PK in patients with stable kidney transplantation of 2 study centers.
Elderly kidney transplant recipients receiving rabbit antithymocyte globulin did not experience different short-term graft survival, graft function or rates of infection, malignancy or hematologic adverse reactions than did nonelderly patients; they experienced fewer episodes of delayed graft function, but had lower 3-year patient survival.
This article provides an update of the literature on the use of extended release once-daily tacrolimus in solid organ transplant recipients.

Our results confirm the impact of the CYP3A4*22 allele on TAC pharmacokinetics, as a second significant genetic factor (in addition to the CYP3A5*1 allele) influencing TAC dose-adjusted blood concentrations in kidney transplant recipients.

Great Dane dogs with DCM demonstrate abnormal calstabin2 and triadin expression. These changes likely affect Ca2+ flux within cardiac cells and may contribute to the pathophysiology of disease. Microarray-based analysis identifies calstabin2, triadin, and RyR2 function as targets of future study.
Desensitization in LDKT appears to offer an acceptable option for highly sensitized patients. In our series, 41% presented an AMR and 12.5% showed transplant glomerulopathy in protocol and/or indication biopsies. However, short-term outcomes and graft survival were satisfactory.
Hyperuricemia is common in pediatric renal transplant recipients, and it is associated with poor allograft outcomes. Hyperuricemia occurs early after transplant and is associated with use of diuretics, cyclosporine therapy, a history of hyperuricemia, and decreased glomerular filtration rate. We aimed to investigate causes and effects of hyperuricemia on allograft outcomes in our patients.

Efficacy was similar between the low-level FK778 and MMF groups. Increased FK778 exposure was poorly tolerated and did not improve efficacy.
