Conjunctival T Cell Profile in Allogeneic Hematopoietic Stem Cell Transplant Patients after Instilling Topical Cyclosporine-A 0.1% Cationic Emulsion.

ABSTRACT:

Introduction

To profile conjunctival T cell populations in allogeneic hematopoietic stem cell transplant (HSCT) patients after instillation of daily topical cyclosporine-A (CsA) 0.1% cationic emulsion (Ikervis), and to evaluate patients' tolerance to these eye drops.

Methods

Nineteen participants were prescribed Ikervis prophylaxis once daily to both eyes from 3-5 weeks pre-HSCT to 12 months post-HSCT. The outcome measure was conjunctival T cell proportions from flow cytometry after impression cytology. Covariates included visual acuity, intraocular pressure, slit lamp and fundal examination, dry eye (SPEED) and quality of life questionnaires, non-invasive keratograph tear break-up time (NIKBUT), conjunctival redness, meibography, lipid thickness, Schirmer test, tear cytokines, fluorescein staining, tear osmolarity, and meibomian gland expressibility.

Results

The conjunctival T cell analysis showed either stable or decreased proportions of conjunctival CD4 T cells at the last visit from baseline in compliant patients. CD4 proportions were increased in non-compliant patients and in the single patient who developed ocular graft-versus-host disease (GVHD). All patients were tolerant to Ikervis but 6/19 were not compliant. In the majority of patients, vision did not affect activities of daily living. Pre- and post-HSCT up to the last study visit, there was no statistically significant change in clinical covariates. Only one participant developed ocular GVHD at 9 months post-HSCT.

Conclusion

Superficial conjunctival T cell profile reflects compliance to daily topical Ikervis eye drops and clinical ocular surface parameters in allogenic HSCT patients. Tolerance is comparable to other formulations of topical CsA in the first 12 months.

Project description:IntroductionThe PERSPECTIVE study evaluated, in routine clinical practice, the effectiveness, tolerability and safety of cyclosporine A (CsA) 0.1% cationic emulsion (CE) in controlling severe keratitis in adults with dry eye who remained insufficiently controlled despite artificial tear (AT) use.MethodsA prospective, multicenter, observational study was conducted at 44 ophthalmology clinics across Finland, Germany, Norway, Sweden and the UK. Adults treated with ATs for severe keratitis and dry eye received CsA 0.1% CE therapy (1 drop in both eyes at bedtime) and were followed up at weeks 4, 12 and 24 and at month 12. Primary endpoint was mean [standard deviation (SD)] change from baseline in corneal fluorescein staining (CFS; Oxford Grade Scale) at month 12 following CsA 0.1% CE initiation. Secondary endpoints examined ocular sign and symptom severity and adverse events (AEs).ResultsThe full analysis set included 472 adults (75.9% female). Mean (SD) age was 61.9 (15.41) years. Mean (SD) CFS score was significantly reduced from baseline [2.56 (1.10)] at month 12 [1.10 (SD 1.13); P < 0.0001]. CFS score reductions were statistically significant from week 4, with further incremental decreases reported at study visits through month 12 (P < 0.0001). Severity of eyelid and conjunctival erythema was significantly reduced from baseline at week 4 and maintained through month 12 (P < 0.001). Tear film breakup time increased significantly from baseline at all study visits through month 12 (P < 0.001). Ocular symptom severity was significantly reduced from baseline at all study visits through month 12 (P < 0.001). Overall, 101 treatment-related AEs were reported. Most were mild/moderate (83.6%) and resolved by month 12 (73.3%).ConclusionsIn routine clinical practice, CsA 0.1% CE provided statistically significant reductions in dry eye signs and symptoms. Improvements were seen at week 4 and maintained over 12 months. Treatment tolerability was good and consistent with previous CsA 0.1% CE clinical studies.Trial registrationEU PAS register number: EUPAS 22376.

Project description:Importance:Studies demonstrating improved survival after allogeneic hematopoietic cell transplant generally exclude infants. Objective:To analyze overall survival trends and other outcomes among infants who undergo allogeneic hematopoietic cell transplant. Design, Setting, and Participants:In this cohort study, we used time-trend analysis to evaluate 3 periods: 2000 through 2004, 2005 through 2009, and 2010 through 2014. The study was conducted in a multicenter setting through the Center for International Blood and Marrow Transplant Research, which is made up of a voluntary working group of more than 450 transplant centers worldwide. Two groups of infants aged 1 year or younger in 2 cohorts were included: those with malignant conditions, such as leukemia, and those with nonmalignant disorders, including immunodeficiencies. Data analysis was conducted from July 2017 to December 2018. Exposures:Allogeneic hematopoietic cell transplant. Main Outcomes and Measures:Survival trends, disease relapse, and toxicity. Results:A total of 2498 infants with a median age of 7 months (range, <1-12 months) were included. In the nonmalignant cohort (n = 472), survival rates improved from the first to the second period (hazard ratio, 0.77 [95% CI, 0.63-0.93]; P = .007) but did not change after 2004. Compared with infants with nonmalignant diseases (n = 2026; 3-year overall survival: 2000-2004, 375/577 [65.0%]; 2005-2009, 503/699 [72.0%]; and 2010-2014, 555/750 [74.0%]), those with malignant conditions had poorer survival rates, without improvement over time (3-year overall survival: 2000-2004, 109/199 [54.8%]; 2005-2009, 104/161 [64.6%]; and 2010-2014, 66/112 [58.9%]). From 2000 through 2014, relapse rates increased in infants with malignant conditions (3-year relapse rate: 2000-2004, 19% [95% CI, 14%-25%]; 2005-2009, 23% [95% CI, 17%-30%]; 2010-2014, 36% [95% CI, 27%-46%]; P = .01). Sinusoidal obstruction syndrome was frequent, occurring with a cumulative incidence of 13% (95% CI, 11%-16%) of infants with nonmalignant diseases and 32% (95% CI, 22%-42%) of those with malignant diseases. Generally, recipients of human leukocyte antigen-identical sibling bone marrow grafts had the best outcomes. Conclusions and Relevance:Survival rates have not improved for infants with malignant diseases over the 15-year study period. Infants with nonmalignant diseases had improved survival rates in the earlier but not the later study period. Higher relapses for the malignant cohort and toxicities for all infants remain significant challenges. Strategies to reduce relapse and toxicity and optimize donor and graft selection may improve outcomes in the future.
