Insights
Long-term use of hydroxychloroquine (HCQ) did not prevent a patient from contracting COVID-19. Further research is needed to determine if HCQ helps alleviate COVID-19 symptoms or reduces hospital stays.
Area of Science:
- Infectious Diseases
- Rheumatology
- Pharmacology
Background:
- The COVID-19 pandemic highlights the urgent need for effective treatments, with hydroxychloroquine (HCQ) being a subject of significant debate regarding its efficacy.
- This report details a case of a patient with rheumatoid arthritis on long-term HCQ treatment who contracted COVID-19.
Observation:
- A 63-year-old female rheumatoid arthritis patient on long-term HCQ (200 mg/day) contracted COVID-19.
- The patient presented with pneumonia, lymphopenia, elevated hs-CRP, and IL-6.
- She received standard COVID-19 treatment alongside HCQ.
Findings:
- Long-term hydroxychloroquine use did not confer immunity against SARS-CoV-2 infection.
- The patient recovered from COVID-19, developing antibodies post-treatment.
- The study did not definitively prove or disprove HCQ's efficacy in symptom management or hospital stay duration.
Implications:
- This case suggests that HCQ may not prevent COVID-19, even with prolonged use.
- Further clinical trials are necessary to evaluate HCQ's therapeutic potential in COVID-19 patients.
- Investigating HCQ's interaction with COVID-19 in patients with underlying autoimmune diseases is warranted.
Introduction:
Current pandemic of the coronavirus induced disease 2019 (COVID-19) presents an urgent issue to the world due to lack of vaccine and medication. Hydroxychloroquine (HCQ) has generated a lot of controversies whether it is effective in prevention and treatment of COVID-19. Current report presents a 63-year-old woman who has taken HCQ for many years but still infected by COVID-19.
Case Presentation:
A patient with rheumatoid arthritis came to the clinic with fever and sore throat. The patient has been treated with 200 mg HCQ per day since 2016. Laboratory tests showed that the patient had lymphopenia, increased levels of high-sensitive C-reactive protein (hs-CRP) and serum Interleukin-6 (IL-6). Chest radiography showed that the patient had pneumonia. Throat swab test confirmed COVID-19 positive. On admission, she was treated with nebulized interferon alfa-2b, oral Lopinavir/Ritonavir, and ceftriaxone sodium for the COVID-19 in addition to HCQ. The patient stayed in hospital for 18 days, recovered from oxygen intake, and eventually discharged from hospital. Follow up investigation showed the patient developed antibody against COVID-19.
Conclusions:
Long-term application of HCQ could not prevent COVID-19 infection, but whether HCQ exerts benefit to alleviation of clinical symptoms and duration of hospital stays remains to be further investigated.
