Abstract

Background and objectives: Vitamin D deficiency in viral infection associated with autoimmune diseases is well documented. This study assessed the prevalence of JC virus in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), and its correlation with vitamin D level.

Materials and methods: Serum and urine samples were collected from 50 patients with RA and SLE. DNA was extracted and subjected to PCR test. Positive PCR products were sequenced, phylogenetic tree was constructed to determine the JC virus genotype. The patient's vitamin D level was evaluated.

Results: Of 50 patients, 19 (38%) were diagnosed as RA, and 31 (62%) were identified as SLE. JC virus DNA was detected in 17 (34%) patients' urine samples including 5 (26.3%) RA and 12 (38.7%) SLE cases. JC virus DNA was detected 2 (4%) in patients' serum samples (one RA. and one SLE). JC virus genotype 3A was dominant. Interestingly, the SLE patients with positive JC virus showed lowered vitamin D compared to patients with negative JC virus (P<0.005).

Conclusion: Given the high rate of JC virus, DNA detection and susceptibility of patients for PML development, it is recommended that detection of JC virus DNA and vitamin D level should be implemented for patients with RA/SLE prior to treatment.

类风湿性关节炎和系统性红斑狼疮患者的 JC 多瘤病毒流行率及其与维生素 D 水平的相关性。

背景和目的：与自身免疫性疾病相关的病毒感染导致的维生素 D 缺乏已得到充分证实。本研究评估了类风湿性关节炎（RA）和系统性红斑狼疮（SLE）患者中 JC 病毒的感染率及其与维生素 D 水平的相关性：收集了 50 名类风湿关节炎和系统性红斑狼疮患者的血清和尿液样本。提取 DNA 并进行 PCR 检测。对阳性 PCR 产物进行测序，构建系统发生树以确定 JC 病毒基因型。对患者的维生素 D 水平进行了评估：50名患者中，19人（38%）被诊断为RA，31人（62%）被确定为系统性红斑狼疮。在 17 名（34%）患者的尿液样本中检测到了 JC 病毒 DNA，其中包括 5 名（26.3%）RA 患者和 12 名（38.7%）系统性红斑狼疮患者。在患者的血清样本中检测到了 2 份（4%）JC 病毒 DNA（1 份为 RA，1 份为系统性红斑狼疮）。JC病毒的基因型为3A。有趣的是，与 JC 病毒阴性的患者相比，JC 病毒阳性的系统性红斑狼疮患者的维生素 D 含量较低：鉴于 JC 病毒、DNA 的高检出率以及患者对 PML 的易感性，建议在治疗前对 RA/SLE 患者进行 JC 病毒 DNA 和维生素 D 水平的检测。

期刊介绍： The Iranian Journal of Microbiology (IJM) is an international, multi-disciplinary, peer-reviewed journal that provides rapid publication of the most advanced scientific research in the areas of basic and applied research on bacteria and other micro-organisms, including bacteria, viruses, yeasts, fungi, microalgae, and protozoa concerning the development of tools for diagnosis and disease control, epidemiology, antimicrobial agents, clinical microbiology, immunology, Genetics, Genomics and Molecular Biology. Contributions may be in the form of original research papers, review articles, short communications, case reports, technical reports, and letters to the Editor. Research findings must be novel and the original data must be available for review by the Editors, if necessary. Studies that are preliminary, of weak originality or merely descriptive as well as negative results are not appropriate for the journal. Papers considered for publication must be unpublished work (except in an abstract form) that is not under consideration for publication anywhere else, and all co-authors should have agreed to the submission. Manuscripts should be written in English.
