ABSTRACT

OBJECTIVES: Hydroxychloroquine/chloroquine has been widely used as part of the standard treatment for patients with coronavirus disease 2019 (COVID-19). We conducted a systematic review and meta-analysis to determine whether hydroxychloroquine/chloroquine increases the risk of acute kidney injury (AKI) in COVID-19 patients. METHODS: PubMed and Embase were searched for related publications from inception to Dec 31, 2021, including randomized controlled trials (RCTs) and non-randomized studies of interventions (NRSIs) comparing the risk of AKI and/or increased creatinine in COVID-19 patients receiving hydroxychloroquine/chloroquine and other controls (active treatment and placebo). We conducted separate meta-analyses for RCTs and NRSIs based on fixed-effect model, with odds ratios (ORs) being considered as effect sizes. RESULTS: We included 21 studies in the analysis, with 12 were RCTs. Based on the RCTs, compared to placebo, the OR was 1.19 (95% confidence interval [CI]: 0.86, 1.64; p = .30, n = 4, moderate quality) for AKI and 1.00 (95%CI: 0.64, 1.56; p = .99, n = 5, moderate quality) for increased creatinine for patients received hydroxychloroquine/chloroquine treatment; compared to active treatment, the odds was 1.28 (95%CI: 0.65, 2.53; p = .47, n = 2, low quality) for AKI and 0.64 (95%CI: 0.13, 3.20; p = .59, n = 1, low quality) for increased creatine. Evidence from NRSIs showed slightly increased odds of AKI, with low quality. CONCLUSION: Based on current available studies which were graded as low to moderate quality, there is insufficient evidence to conclude that hydroxychloroquine/chloroquine use is associated with increased risk of AKI or raised creatinine.

ABSTRACT

This article aims to understand the changes in the detection rates of H5, H7, and H9 subtypes of avian influenza viruses (AIVs) in the live poultry markets (LPMs) in Nanchang City, Jiangxi Province, before and after the outbreak of the COVID-19. From 2019 to 2020, we monitored the LPM and collected specimens, using real-time reverse transcription polymerase chain reaction technology to detect the nucleic acid of type A AIV in the samples. The H5, H7, and H9 subtypes of influenza viruses were further classified for positive results. We analyzed 1,959 samples before and after the outbreak and found that the positive rates of avian influenza A virus (39.69%) and H9 subtype (30.66%) after the outbreak were significantly higher than before the outbreak (26.84% and 20.90%, respectively; P < 0.001). In various LPMs, the positive rate of H9 subtypes has increased significantly (P ≤ 0.001). Positive rates of the H9 subtype in duck, fecal, daub, and sewage samples, but not chicken samples, have increased to varying degrees. This study shows that additional measures are needed to strengthen the control of AIVs now that LPMs have reopened after the relaxing of COVID-19-related restrictions.

ABSTRACT

RATIONALE: Hydroxychloroquine has excellent anti-inflammatory and immunomodulatory effects as one of the antimalarial drugs. In particular, hydroxychloroquine was once widely used as a treatment for the new coronavirus pneumonia epidemic in 2020. Retinopathy caused by hydroxychloroquine is normally irreversible, but little attention has been paid to it. PATIENT CONCERNS: A 38-year-old young Chinese woman was taking oral hydroxychloroquine 400 mg daily to control lupus disease activity for six years after the diagnosis of systemic lupus erythematosus (SLE). She did not have any history of eye disease and was admitted to the hospital with a sudden blurring of both eyes. DIAGNOSES: The diagnosis of retinal macular degeneration caused by hydroxychloroquine was made after excluding other interfering diseases based on the patient's long-term use of hydroxychloroquine and the results of the eye examination. INTERVENTIONS: The patient was discontinued from hydroxychloroquine. To control the recurrence of SLE, she was given intravenous methylprednisolone, oral tacrolimus and mycophenolate. Meanwhile, she was asked to take extra care of her eyes and to come to the hospital every three months to have her vision checked. OUTCOMES: The patient's blurred vision improved one week later. Three months later, her vision examination showed no further decline (0.4 in the right eye and 0.6 in the left eye). Meanwhile, the SLE disease activity index (SLEDAI) decreased from six points to five points currently. LESSONS: Retinopathy caused by hydroxychloroquine is irreversible and there is no particularly effective treatment. Discontinuation of hydroxychloroquine, better daily eye protection, and regular vision checks are the keys to preventing retinopathy. Although hydroxychloroquine causing retinal toxicity was mentioned several years ago, the rate and severity of retinal toxicity require further research. How to get more patients to take care of their eyes requires continuous and increased education by doctors.
