ABSTRACT
Thyroid eye disease (TED), also known as Graves' orbitopathy or ophthalmopathy (GO) or Graves' eye disease, is an autoimmune condition of the retroocular tissues associated with Graves' disease. In isolated GO, the patient can present without thyroid hormone dysfunction or systemic symptoms of Graves' disease, in which case it is called euthyroid Graves' ophthalmopathy (EGO). It is very rare for this condition to have negative thyroid-stimulating hormone receptor (TSHR) autoantibodies, and we present such a rare case of a young female, who had progressive bilateral vision loss, intermittent left-sided retroocular headache, and severe bilateral proptosis. The patient was diagnosed with EGO based on multidisciplinary consults, diagnostic orbital magnetic resonance imaging (MRI) results, and a good response to treatment with intravenous steroids. Later, the patient was followed as an outpatient and treated with thyroid orbitopathy-specific immunotherapy with teprotumumab. The patient's response to teprotumumab was excellent and caused significant improvement in visual acuity, proptosis, and chemosis. This adds valuable literature to the medical field and gives insight to clinicians to consider the diagnosis of GO even with seronegative TSHR autoantibodies and euthyroid hormone status. It also adds to the understanding of the complex pathophysiology of this rare condition.
ABSTRACT
BACKGROUND: The aim of this study was to identify vaginal Lactobacillus spp. and quantify vaginal inflammatory cytokines in primigravida vs. multigravida women and pregnant vs. non-pregnant women. METHODS: Vaginal swabs were obtained from four groups of patients. A real-time PCR was carried out to identify the Lactobacillus spp. Multiplex immunoassays were performed to quantify a total of 27 cytokines using the Bio-Plex MAGPIX multiplex reader and MesoQuick Plex SQ 120 (Meso Scale Diagnostics LLC, Rockville, MD, USA). Inferential statistics using hypothesis tests were applied to detect differences in cytokine levels. RESULTS: Significant differences in cytokines and chemokines exist among the four populations of women studied. IP-10 is significantly higher in multigravida women as compared to primigravida women. IFN-γ, MCP-1, MIP-1ß, IL-2 and IL-10 are significantly higher in non-pregnant women compared to pregnant women. L. iners was the most abundant species in multigravida, pregnant and non-pregnant patients, while L. crispatus was the most abundant species in primigravida patients. Significant differences in the levels of MIP-1ß, TNF-α, PDGF-BB, VEGF-A, IL-12, and IL-10 exist between women identified with Lactobacillus species and women not identified with Lactobacillus species. CONCLUSIONS: There were significant differences regarding cytokines, chemokines, and Lactobacillus spp. among four groups of studied patients. With these results, we increase our understanding of the role that vaginal cytokines and Lactobacillus species have during pregnancy, with the goal that this novel research will be useful for examining vaginal biomarkers in obstetrical conditions.
