Vitamin D deficiency after allogeneic hematopoietic cell transplantation promotes T-cell activation and is inversely associated with an EZH2-ID3 signature. Transplant Cell Ther 2022; 28:18.e1-18.e10. [PMID: 34597852 PMCID: PMC8792200 DOI: 10.1016/j.jtct.2021.09.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 07/10/2021] [Accepted: 09/22/2021] [Indexed: 01/03/2023]
Abstract
Vitamin D promotes a shift from a proinflammatory to a more tolerogenic immune state in allogeneic hematopoietic cell transplant (HCT) recipients. The dominant mechanism responsible for this shift has not been elucidated. We took a multifaceted approach to evaluating the clinical and immunologic impact of low vitamin D levels in 53 HCT recipients. We used 28-plex flow cytometry for immunophenotyping, serum cytokine levels, T-cell cytokine production, and T-cell whole genome transcription. The median day-30 vitamin D level was 20 ng/mL, and deficiency was common in younger patients undergoing myeloablative transplantation. Low vitamin D levels were associated with a high CD8/Treg ratio, increased serum levels and T-cell production of proinflammatory cytokines, and a gene expression signature of unrestrained T-cell proliferation and epigenetic modulation through the PRC2/EZH2 complex. Immunophenotyping confirmed a strong association between high levels of vitamin D and an activated EZH2 signature, characterized by overexpression of ID3, which has a role in effector T-cell differentiation. Our findings demonstrate the critical role of vitamin D in modulating T-cell function in human GVHD and identify a previously undescribed interaction with EZH2 and ID3, which may impact effector differentiation and has implications to cell therapies and other forms of cancer immunotherapy. © 20XX American Society for Blood and Marrow Transplantation.

Abstract
BACKGROUND Patients with vitiligo present with different repigmentation patterns in the early recovery stage. OBJECTIVES To analyze the relationships between early repigmentation patterns in vitiliginous patches, their clinical characteristics, and therapeutic choices. METHODS Patients with vitiligo seen in the Department of Dermatology, The First Affiliated Hospital of Nanjing Medical University from 2010 to 2015, were included, and their clinical records, especially photographs and medical treatments, were reviewed. RESULTS One hundred and sixteen patients were included in this study, and 326 lesions with different degrees of depigmentation, locations, stages, distributions, therapies, and repigmentation patterns were included and analyzed. Perifollicular repigmentation occurred more frequently in lesions with complete depigmentation (P = 0.005), in non-sun exposed areas (P < 0.001), a stable stage (P = 0.008), and lesions treated with narrow band ultraviolet B (NB-UVB) (P < 0.001, despite lesion distributions). Marginal repigmentation is more frequent in lesions with complete depigmentation (P = 0.016), lesions treated without NB-UVB (P = 0.002), and facial lesions treated with topical vitamin D analogs (TVDAs) monotherapy (P = 0.022). Diffuse repigmentation is the predominant pattern in lesions with incomplete depigmentation (P < 0.001), in sun-exposed areas (P < 0.001), progressive stage (P = 0.044), and truncal lesions treated with TVDAs (P < 0.001). CONCLUSIONS The different repigmentation patterns of vitiligo lesions depend on the different source and status of melanocytes and their abilities to produce melanin on the choice of therapy.

Abstract
BACKGROUND Vitiligo is a common disorder of depigmentation that has been associated with other autoimmune diseases. No recent large-scale data exist on the rates of comorbidities associated with vitiligo from the United States population. OBJECTIVES To identify the prevalence of comorbidities as well as associated laboratory abnormalities in vitiligo patients. METHODS All medical records dating from January 1, 2000 to June 21, 2011 within the Research Patient Data Repository were evaluated retrospectively using a novel artificial intelligence-based computer program. A total of 3,280 patients carrying the diagnosis of vitiligo were identified using ICD-9 code 709.01. We randomly selected 300 patients and validated the diagnosis by manually reviewing their medical records. These results were used to create a model that was then applied to the larger set yielding 2,441 true vitiligo patients. 1,657 (68%) were diagnosed by dermatologists and 784 (32%) by non-dermatologists. We identified the prevalence of other comorbid autoimmune conditions by searching problem lists of vitiligo patients and collected laboratory data from the first available data point in the system for each patient. RESULTS Women were more frequently represented (57.6%) than men (42.4%). The majority of vitiligo patients were White/Caucasian (56.9%), followed by Hispanic/Latino (19.4%). 565 (23%) had one of the following comorbidities: 287 thyroid-related, 186 psoriasis, 72 rheumatoid arthritis, 59 alopecia areata, 55 inflammatory bowel disease, 53 systemic lupus and 20 type I diabetes mellitus. 41% had elevated anti-nuclear antibody levels. Almost half of the patients tested had elevated thyroid peroxidase antibodies. Over 50% of the patients tested had low or insufficient levels of 25-OH vitamin D. CONCLUSION We found a high prevalence of comorbidities among individuals with vitiligo presenting to teaching hospitals in Boston, Mass. Comorbid autoimmune conditions were seen in 23% of vitiligo patients, thyroid disorders and psoriasis being the most common. Screening for these conditions, especially thyroid disorders, should be considered in vitiligo patients.

Abstract
Post pathogen invasion, migration of effector T-cell subsets to specific tissue locations is of prime importance for generation of robust immune response. Effector T cells are imprinted with distinct “homing codes” (adhesion molecules and chemokine receptors) during activation which regulate their targeted trafficking to specific tissues. Internal cues in the lymph node microenvironment along with external stimuli from food (vitamin A) and sunlight (vitamin D3) prime dendritic cells, imprinting them to play centre stage in the induction of tissue tropism in effector T cells. B cells as well, in a manner similar to effector T cells, exhibit tissue-tropic migration. In this review, we have focused on the factors regulating the generation and migration of effector T cells to various tissues along with giving an overview of tissue tropism in B cells.

Abstract
BACKGROUND Papular urticaria by flea bite is a chronic allergic condition in which clinical improvement may occur at the age of 7 years, thus representing a natural model of acquired immunologic tolerance in humans. The aim of this study was to characterize regulatory cells and specific responses to flea antigens of CD4(+) T lymphocytes expressing cutaneous migration markers in patients with papular urticaria caused by flea bite and with different disease evolution times. METHODS Cell populations were characterized by flow cytometry in samples from patients and healthy controls. Specific cell stimulation was performed with a complete flea body extract. The Mann-Whitney U test was used for comparisons. RESULTS Total dendritic cells were lower in patients than in healthy controls. No quantitative differences were found in CD4 regulatory T cells. CD4(+) T cells from patients produced more IL-4, lL-10, IL-17, and IFN-γ. Patients who experienced the onset of symptoms within the first 5 years of age showed a greater percentage of local (cutaneous lymphocyte antigen +) IL-4- and IL-17-producing cells, while patients who experienced the onset of symptoms after the age of 5 years had a higher percentage of systemic (cutaneous lymphocyte antigen -) IL-10-producing cells. CONCLUSION Analysis of the cellular immune response against whole flea antigen in patients with papular urticaria by flea bites suggests a possible participation of inflammatory cytokines in the skin reaction (Th17) and a systemic control mechanism (IL-10). This pattern of cytokine production in patients could be a consequence of an impaired dendritic cell population.

Abstract
We report here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of keratinocytes differentiation and anti-proliferative effects. Vitamin D3 analog is also reported to suppress T-cell mediated immunity, T-cell skin recruitment, and skin infiltration via down-regulating cutaneous lymphocyte antigen expression. Furthermore, vitamin D3 compounds are known to influence melanocyte maturation and differentiation and also to up-regulate melanogenesis. Autoreactive lymphocytes against melanocytes are one of the causes. Topical vitamin D3 analog may control vitiligo itself, however stronger immunosuppressive effects of topical corticosteroid may contribute to rapid re-pigmentation suppressing auto-reactive lymphocytes. The topical combination therapy is a simple, effective and safe option for vitiligo vulgaris in sun-exposed areas.

Abstract
Nonsegmental vitiligo is a depigmented skin disorder showing acquired, progressive, and depigmented lesions of the skin, mucosa, and hair. It is believed to be caused mainly by the autoimmune loss of melanocytes from the involved areas. It is frequently associated with other autoimmune diseases, particularly autoimmune thyroid diseases including Hashimoto's thyroiditis and Graves' disease, rheumatoid arthritis, type 1 diabetes, psoriasis, pernicious anemia, systemic lupus erythematosus, Addison's disease, and alopecia areata. This indicates the presence of genetically determined susceptibility to not only vitiligo but also to other autoimmune disorders. Here, we summarize current understanding of autoimmune pathogenesis in non-segmental vitiligo.

Abstract
BACKGROUND Vitamin D deficiency could be associated with the prevalence of atopic dermatitis (AD). OBJECTIVES We carried out a study to see whether deficient/insufficient levels of vitamin D correlate with the severity of atopic skin disease. METHODS Using the SCORAD index, we evaluated the severity of disease in 37 children (17 girls and 20 boys) aged between 8 months and 12 years with AD, consecutively enrolled in the study. Serum levels of 25-hydroxyvitamin D [25(OH)D] were determined by a chemiluminescent method. Specific IgE (sIgE) to Staphylococcus aureus enterotoxins and sIgE to Malassezia furfur were assayed by the ImmunoCAP system. anova and the Pearson correlation test were used for statistical evaluation. RESULTS We found severe, moderate and mild AD in nine (24%), 13 (35%) and 15 (41%) children, respectively. Mean ± SD serum levels of 25(OH)D were significantly higher (P < 0·05) in patients with mild disease (36·9 ± 15·7 ng mL(-1)) compared with those with moderate (27·5 ± 8·3 ng mL(-1)) or severe AD (20·5 ± 5·9 ng mL(-1)). The prevalence of patients with sIgE to microbial antigens increased in relation to vitamin D deficiency and AD severity. CONCLUSIONS These data suggest that vitamin D deficiency may be related to the severity of AD and advocate the need for studies evaluating the use of vitamin D as a potential treatment in patients with this disease.
