Plummer-Vinson syndrome in primary Sjögren syndrome: a case-based review

Abstract

This study aimed to describe a patient with Sjögren syndrome who developed Plummer-Vinson syndrome, and to review the literature and describe shared aspects of this rare association. A systematic screening of articles was conducted in PubMed/MEDLINE, LILACS, SciELO, Scopus, Web of Science, and Cochrane, dating 1940 to 2020. All the articles included the association between Sjögren syndrome and Plummer-Vinson syndrome. No language restriction was applied. The following terms were used: "Sjögren syndrome" or "sicca syndrome" and "Plummer-Vinson syndrome" or "Paterson-Kelly syndrome." We performed our analysis by adding our present case, with a total of 4 cases. Three out of four were female (75%), age varied from 56 to 58years old. In 2 cases, Sjögren syndrome preceded Plummer-Vinson syndrome diagnosis, and in 1 report, Plummer-Vinson syndrome appeared before Sjögren syndrome. Disease duration varied from 7 to 20years. In two cases, autoantibodies were available, and antinuclear antibodies and anti-Ro/SS-A were positive in both, and anti-La/SS-B in one of them was associated with anti-dsDNA; however, no data regarding lupus was available in the article. Treatment involved iron supplementation in 3/3. Two out of three received parenteral iron supplementation, and in these two cases, mechanical esophageal dilatation was needless. In the other case, an additional endoscopic esophageal dilatation was necessary to receive the oral iron supplement. All 3 cases had a good outcome. This case illustrates a patient with Sjögren syndrome who developed the rare Plummer-Vinson syndrome. In Sjögren syndrome, the presence of iron-deficiency anemia, dysphagia, and weight loss should alert the physician to search for associated Plummer-Vinson syndrome.
