Abstract
NSI‐566 is a stable, primary adherent neural stem cell line derived from a single human fetal spinal cord and expanded epigenetically with no genetic modification. This cell line is being tested in clinical trials in the U.S. for treatment of amyotrophic lateral sclerosis and spinal cord injury. In a single‐site, phase I study, we evaluated the feasibility and safety of NSI‐566 transplantation for the treatment of hemiparesis due to chronic motor stroke and determined the maximum tolerated dose for future trials. Three cohorts (n = 3 per cohort) were transplanted with one‐time intracerebral injections of 1.2 × 107, 2.4 × 107, or 7.2 × 107 cells. Immunosuppression therapy with tacrolimus was maintained for 28 days. All subjects had sustained chronic motor strokes, verified by magnetic resonance imaging (MRI), initiated between 5 and 24 months prior to surgery with modified Rankin Scores [MRSs] of 2, 3, or 4 and Fugl‐Meyer Motor Scores of 55 or less. At the 12‐month visit, the mean Fugl‐Meyer Motor Score (FMMS, total score of 100) for the nine participants showed 16 points of improvement (p = .0078), the mean MRS showed 0.8 points of improvement (p = .031), and the mean National Institutes of Health Stroke Scale showed 3.1 points of improvement (p = .020). For six participants who were followed up for 24 months, these mean changes remained stable. The treatment was well tolerated at all doses. Longitudinal MRI studies showed evidence indicating cavity‐filling by new neural tissue formation in all nine patients. Although this was a small, one‐arm study of feasibility, the results are encouraging to warrant further studies. stem cells translational medicine2019;8:999–1007

Abstract
BACKGROUND There are very few reports describing the development of gallstone disease after renal transplantation (GSDART) in Asia. The aim of this population-based study was to explore the prevalence, predictive factors, and outcomes of newly developed GSDART. The relationship between immunosuppressant and GSDART was also explored. PATIENTS AND METHODS Renal transplantation (RT) recipients were identified from the National Health Insurance Research Database of Taiwan during January 1998-December 2012. In total, 2,630 adult patients, who had neither been diagnosed with gallstone disease (GSD) nor undergone cholecystectomy, were included in this study. These patients underwent follow-up till the diagnosis of GSDART was established. Risk factors and post-RT immunosuppressant treatments were investigated and analyzed using Cox regression analysis. The cumulative mortality in patients with and without GSDART was also evaluated. RESULTS The final dataset comprised 143 patients who developed GSDART and 2,487 patients who had not been diagnosed with GSDART during the follow-up period. The prevalence of GSDART was 5.4%. On performing univariate analysis, age (p=0.0276) and certain immunosuppressant administrations were identified as significant risk factors for GSDART. After adjusting for age, multivariable analysis showed that everolimus (adjusted hazard ratio 0.287, p=0.0013) was independently associated with the development of GSDART. The overall mortality rate (6.99%, p=0.0341) was significantly decreased in the GSDART group. CONCLUSION Increased age was the most consistent risk factor for GSD, and everolimus-based immunotherapy indicated a decreased incidence of GSDART in RT recipients. The long-term mortality rate was significantly decreased in patients with GSDART.

Acute cholecystitis is a common complication after allogeneic stem cell transplantation and is associated with the use of total parenteral nutrition. Biol Blood Marrow Transplant 2014; 21:768-71. [PMID: 25543093 DOI: 10.1016/j.bbmt.2014.12.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2014] [Accepted: 12/01/2014] [Indexed: 02/07/2023]
Abstract
The incidence and risk factors for acute cholecystitis after allogeneic hematopoietic stem cell transplantation (HSCT) are not well defined. Of 644 consecutive adult transplants performed at our institution between 2001 and 2011, acute cholecystitis occurred in the first year of transplant in 32 patients (5.0%). We conducted 2 retrospective case-control studies of this population to determine risk factors for cholecystitis after HSCT and to evaluate the performance of different methods of imaging to diagnosis cholecystitis in patients undergoing HSCT compared with non-HSCT patients. In the HSCT population, development of cholecystitis was associated with an increased 1-year overall mortality rate (62.5% versus 19.8%, P < .001). The risk of developing cholecystitis was higher in patients who received total parenteral nutrition (TPN) (adjusted odds ratio, 3.41; P = .009). There was a trend toward more equivocal abdominal ultrasound findings in HSCT recipients with acute cholecystitis compared with nontransplant patients (50.0% versus 30.6%, P = .06). However, hepatobiliary iminodiacetic acid (HIDA) scans were definitively positive for acute cholecystitis in most patients in both populations (80.0% of HSCT recipients versus 77.4% of control subjects, P = .82). In conclusion, acute cholecystitis is a common early complication of HSCT, the risk is increased in patients who receive TPN, and it is associated with high 1-year mortality. In HSCT recipients with findings suggestive of acute cholecystitis, especially those receiving TPN, early use of HIDA scan may be considered over ultrasound.

Abstract
PURPOSE To determine risk factors for the development of gallstones and the prevalence of related cholecystectomy in children following hematopoietic cell transplantation (HCT). PATIENTS AND METHODS A retrospective chart review of 1343 patients aged below 18 years old who survived at least 1 year after HCT from 1969 to 2011 was performed. Multivariate Cox regression models were used to estimate the hazard ratio (HR) of risk factors associated with gallstones. RESULTS Gallstones developed in 91 patients, a median of 3.5 (range, 0.1 to 30.9) years after HCT at 16.3 (range, 0.8 to 44.2) years of age, with a 40-year cumulative incidence of 11%. At initial diagnosis, 61 (67%) patients were symptomatic and 30 (23%) had incidental gallstones. Risk factors associated with gallstones included autologous transplant (HR=2.7, P=0.02), unrelated donor (HR=2.0, P=0.05), grade 3 to 4 acute graft-versus-host disease (GVHD) (HR=2.2, P=0.03), chronic GVHD (HR=2.0, P=0.05), second transplant (HR=2.3, P=0.03), diabetes (HR=2.2, P=0.05), and estrogen therapy (HR=1.8, P=0.03). Fifty-six patients underwent cholecystectomy. The prevalence of cholecystectomy among 853 surviving patients was 5.2%. CONCLUSIONS Childhood HCT patients have an increased risk of developing gallstones.

Abstract
AIM To determine the steady state concentration and the pharmacokinetics of Cyclosporine A (CsA) in heart transplant recipients. METHODS A single dose of 100 mg CsA capsules twice daily was given to five heart transplant recipients of steady state. The concentrations of CsA in plasma were determined by streptavidin peroxidase fluorescent polarization immunoassay. RESULTS The main pharmacokinetic parameters of CsA were as follows: t(max) (1.60 ± 0.55) h, ρmax(951.60 ± 229.20) μg.L-1, t1/2(6.53 ± 2.40) h, and AUC0 -t(5162.10 ± 1355.01) μg.h.L-1. CONCLUSION The study obtained the steady state pharmacokinetic parameters of CsA in Chinese heart transplant recipients.
