Abstract
Immune-mediated neuropathies (IMNs) following hematopoietic stem cell transplantation have been described recently, which, excluding Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy, may present with atypical patterns. This retrospective, nested, case-control study reviewed data from 3858 patients who received haploidentical hematopoietic stem cell transplantation (haplo-HSCT) during the past 10 years at a single center, and 40 patients (1.04%) with IMN following haplo-HSCT were identified. Chronic graft-versus-host disease (cGVHD) (P = .043) and cytomegalovirus (CMV) viremia (P = .035) were recognized as independent risk factors for the development of IMN after haplo-HSCT. There were no significant differences in overall survival (P = .619), disease-free survival (P = .609), nonrelapse mortality (P = .87), or the incidence of relapse (P = .583) between patients with and without IMN after haplo-HSCT. However, patients with post-transplant IMN were at higher risk of developing cGVHD (P = .012) than patients who did not develop IMN. Twenty-four of the 40 patients with IMN (60%) attained neurologic improvement after treatments including vitamins B1 and B12 and/or immunomodulatory agents. However, 19 (47.5%) patients still had persistent motor/sensory deficits despite receiving timely treatment. More studies are needed to help develop standardized diagnostic and therapeutic strategies for patients with post-transplant IMN.

Pediatric blood & cancer. 2015;(12):2232-4
Abstract
Children undergoing intense cancer treatment frequently require total parenteral nutrition (TPN). Rarely, vitamins are removed due to hypersensitivity to the carrier vehicle in the formulation. We present the case of a 5-year-old patient with stage 4, high-risk neuroblastoma who developed altered mental status, ataxia, and tachycardia during consolidative autologous stem cell transplantation. Skin findings and brain MRI were consistent with thiamine (vitamin B1) deficiency and Wernicke encephalopathy. Vitamin B1 administration rapidly reversed all skin and neurologic symptoms. This case highlights the importance of close monitoring of micronutrients in pediatric patients receiving prolonged courses of chemotherapy and stem cell transplantation.

Abstract
OBJECTIVE To compare the combination of biotin plus thiamine to thiamine alone in treating patients with biotin-responsive basal ganglia disease in an open-label prospective, comparative study. METHODS twenty patients with genetically proven biotin-responsive basal ganglia disease were enrolled, and received for at least 30 months a combination of biotin plus thiamine or thiamine alone. The outcome measures included duration of the crisis, number of recurrence/admissions, the last neurological examination, the severity of dystonia using the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS), and the brain MRI findings during the crisis and after 30 months of follow-up. RESULTS Ten children with a mean age of 6 years(1/2) were recruited in the biotin plus thiamine group (group 1) and ten children (6 females and 4 males) with a mean age of 6 years and 2 months were recruited in the thiamine group (group 2). After 2 years of follow-up treatment, 6 of 20 children achieved complete remission, 10 had minimal sequelae in the form of mild dystonia and dysarthria (improvement of the BFMDRS, mean: 80%), and 4 had severe neurologic sequelae. All these 4 patients had delayed diagnosis and management. Regarding outcome measures, both groups have a similar outcome regarding the number of recurrences, the neurologic sequelae (mean BFMDS score between the groups, p = 0.84), and the brain MRI findings. The only difference was the duration of the acute crisis: group 1 had faster recovery (2 days), versus 3 days in group 2 (p = 0.005). CONCLUSION Our study suggests that over 30 months of treatment, the combination of biotin plus thiamine is not superior to thiamine alone in the treatment of biotin-responsive basal ganglia disease.

Abstract
BACKGROUND The therapeutic efficacy of CP/CPPS is not very satisfactory and the impact on young male's quality of life is considerable. The aim of the present study is to evaluate the efficacy of pollen extract associated with vitamins (DEPROX 500®) in order to improve the quality of life of young patients affected by chronic prostatitis type IIIb (CP/CPPS) by pain relieving. METHODS All patients with clinical and instrumental diagnosis of CP/CPPS (class b) underwent DEPROX 500® 2 tablets in a single dose daily for 30 days. Clinical and microbiological analyses were carried out at the enrolment and after 1 month. NIH-CPSI and IPSS questionnaires have been used. The main outcome measure was the improvement of quality of life at the end of the whole study period, evaluated by questionnaires results. RESULTS 20 men (mean age 32.8 ± 6.78) were enrolled in this pilot study. The baseline questionnaire mean scores were 25.90 ± 2.1 and 8.01 ± 3.64 for NIH-CPSI and IPSS, respectively. At the follow-up examination (1 month after treatment), 18 out of 20 patients (90.0%) reported an improvement of quality of life, in terms of pain reduction. The questionnaire results after 1 month from treatment were as follows: NIH-CPSI 12.8 ± 2.20, IPSS 7.6 ± 1.58. Statistically significant differences were then reported between the two visits, in terms of NIH-CPSI scores (p<0.001). No statistically significant differences have been reported in terms of IPSS between the two groups. All patients were negative at the Meares-Stamey test evaluation. The compliance to the study protocol was 100%. CONCLUSIONS The pollen extract associated with vitamins (DEPROX 500®) significantly improved
total symptoms, pain, and QoL in patients with non-inflammatory CP/CPPS without severe side
effects.

Abstract
BACKGROUND Acute renal failure is a serious complication in critically ill patients and frequently requires renal replacement therapy, which alters trace element and vitamin metabolism. OBJECTIVE The objective was to study trace element balances during continuous renal replacement therapy (CRRT) in intensive care patients. DESIGN In a prospective randomized crossover trial, patients with acute renal failure received CRRT with either sodium bicarbonate (Bic) or sodium lactate (Lac) as a buffering agent over 2 consecutive 24-h periods. Copper, selenium, zinc, and thiamine were measured with highly sensitive analytic methods in plasma, replacement solutions, and effluent during 8-h periods. Balances were calculated as the difference between fluids administered and effluent losses and were compared with the recommended intakes (RI) from parenteral nutrition. RESULTS Nineteen sessions were conducted in 11 patients aged 65 +/- 10 y. Baseline plasma concentrations of copper were normal, whereas those of selenium and zinc were below reference ranges; glutathione peroxidase was in the lower range of normal. The replacement solutions contained no detectable copper, 0.01 micromol Se/L (Bic and Lac), and 1.42 (Bic) and 0.85 (Lac) micromol Zn/L. Micronutrients were detectable in all effluents, and losses were stable in each patient; no significant differences were found between the Bic and Lac groups. The 24-h balances were negative for selenium (-0.97 micromol, or 2 times the daily RI), copper (-6.54 micromol, or 0.3 times the daily RI), and thiamine (-4.12 mg, or 1.5 times the RI) and modestly positive for zinc (20.7 micromol, or 0.2 times the RI). CONCLUSIONS CRRT results in significant losses and negative balances of selenium, copper, and thiamine, which contribute to low plasma concentrations. Prolonged CRRT is likely to result in selenium and thiamine depletion despite supplementation at recommended amounts.

Abstract
The depressed ETKA in ESRD patients is supposed to be caused and/or aggravated by several factors among which the diminished content of thiamine in blood and/or disturbances of thiamine utilization seem to play the major role. This role stems from the fact that thiamine acts as the cofactor of transketolase. In order to check the therapeutic significance of this relationship we introduced the thiamine pyrophosphoric acid ester chloride (Cocarboxylasum-CC) administration in 25 patients (mHD + CC). Immediately after each HD performance CC was given i.v. during 12 weeks in a doses of 5 mg/kg b.w., 3 times a week. The blood for ETKA value, free and total thiamine in plasma and erythrocytes, as well as, the total protein and albumins/globulins index investigation was drawn before, after 6 and 12 weeks of CC administration, and 3 months after cessation of this therapy. In 10 patients, on maintenance HD nontreated by CC (mHD), the blood was drawn at the same time intervals. Normal values we obtained from 15 healthy volunteers. For ETKA evaluation photocolorimetric method was used, thiamine content in blood was estimated by fluorimetric method. At the beginning of the study the mean value of ETKA, in two examined groups, was found statistically decreased (p < 0.01) when compared with normals. Mean values of thiamine in plasma and erythrocytes were lower but did not differ significantly from those in normals. After 6 weeks of CC administration ETKA value increased, but only after 12 weeks it increased significantly (p < 0.01), reaching normal value. On the other hand, striking increase in plasma thiamine and erythrocyte thiamine levels was observed after 6 weeks of CC administration already (p < 0.01). Three months after cessation of CC administration significant decrease in ETKA value and thiamine level in blood was observed (p < 0.01). ETKA returned to lower value than in normals even in the presence of still high thiamine levels in blood. In mHD patients nontreated by CC the ETKA value and thiamine levels in blood did not change significantly during all periods of study. The nutritional status assessed by total protein and albumins/globulins index did not change in both groups through the study. We conclude, the administration of high doses of CC to ESRD patients on maintenance hemodialysis HD was successful in terms of increasing ETKA value and thiamine levels in blood without any side effects. Thus, supplementation with large doses of CC deserves further study because it promises to be another adjunct in the treatment of potential thiamine deficiency and metabolic disturbances in the course of dialysotherapy.
