Case series Patients: Female, 29-year-old • Female, 34-year-old • Female, 24-year-old • Female, 39-year-old • Female, 46-year-old Final Diagnosis: COVID-19 • SARS-CoV-2 Symptoms: Anosmia • asthenia • chest pain • chills • diarrhea • dry cough • dyspnea • fever • headache • myalgias • odynophagia Medication: — Clinical Procedure: — Specialty: Rheumatology OBJECTIVE: Unusual clinical course BACKGROUND: This case series describes 5 patients with SARS-CoV-2 infection and COVID-19 in Ecuador who had been treated with hydroxychloroquine for systemic lupus erythematosus (SLE) prior to their COVID-19 illness. CASE REPORT: Case #1 reports a 29-year-old woman who had been treated with 200 mg of hydroxychloroquine per day for 1 year and presented with flu-like symptoms, chest pain, fever, odynophagia, asthenia, dry cough, and chills. Case #2 was a 34-year-old woman whose treatment for SLE included 200 mg of hydroxychloroquine per day since 2017. She arrived at the clinic with a dry cough, asthenia, and myalgias. Case #3 was a 24-year-old woman who had been using 200 mg of hydroxychloroquine per day since 2010. She presented with asthenia, myalgias, headaches, hypogeusia, and anosmia. Case #4 was a 39-year-old woman taking 200 mg of hydroxychloroquine every day for SLE who presented with dyspnea, chest pain, odynophagia, hypogeusia, anosmia, diarrhea, and fever. Case #5 was a 46-year-old woman who had been taking 200 mg of hydroxychloroquine since 2019. She came to our hospital complaining of chest pain, fever, and dyspnea. In all 5 patients, SARS-CoV-2 infection was confirmed with a nasopharyngeal SARS-CoV-2 reverse transcription-polymerase chain reaction (RT-PCR) test using the Cepheid/GeneXpert system. CONCLUSIONS: All 5 of our patients with SLE who were taking hydroxychloroquine presented with SARS-CoV-2 infection and symptoms of COVID-19. This case series provides support for a lack of prevention of COVID-19 by hydroxychloroquine.
