ABSTRACT
INTRODUCTION: The aim of this study was to systematically review the clinical and paraclinical findings in patients with reactive arthritis (ReA) caused by giardiasis. METHODS: In this study, papers describing ReA in patients with giardiasis were found after searching in international databases including MEDLINE/PubMed, Web of Science, Scopus, and ScienceDirect up to 2021. Google Scholar was also searched to find more articles. RESULTS: Finally, 16 studies met the inclusion criteria with reporting 115 patients, ranging in age from 19 months to 49 years. This disease was more reported in children and adolescents than adults. The most frequently involved joints with arthritis were the knee and ankle followed by the hip, wrist, elbow, shoulder, axial skeleton, metatarsophalangeal, and proximal interphalangeal. The most common extra-articular symptoms included diarrhea, allergic symptoms, and abdominal pain. CONCLUSION: The signs and symptoms of ReA caused by giardiasis can be various, from moderate to severe manifestations. Also, they can be similar to some other diseases, so it is recommended that physicians and specialists have more knowledge about this disease to treat patients with a correct diagnosis.
