SUMMARY OBJECTIVE To present scientific evidence based on a systematic review of the literature (PRISMA), aiming to systematize evidence of the ototoxic effects of hydroxychloroquine (HCQ). METHODS The studies were selected using a combination based on the Medical Subject Headings (MeSH). The databases searched were MEDLINE (PubMed), LILACS, SciELO, and BIREME, encompassing articles from January 2010 to May 2020, with no restrictions of language and place of publication. RESULTS A total of 148 articles with the potential to be included were retrieved. Of these, two answered the research question, which consisted of seeking evidence of the ototoxic effects of hydroxychloroquine. These studies scored 11 in their quality assessment with the modified protocol by Pithon et al.13. CONCLUSIONS The studies reported possible ototoxicity of HCQ. Audiovestibular changes, such as hearing loss, peripheral vestibular syndrome, and tinnitus were evidenced in patients submitted to HCQ. The improvement in the audiological examinations and the regression in the vestibular syndrome after stopping the treatment with HCQ are strong arguments in favor of the ototoxicity caused by this medication. However, there are still divergences about the relationship between ototoxic effects and the use of HCQ.

This study will evaluate the safety, tolerability and efficacy (objective response rate) of using hydroxychloroquine (HCQ) in combination with nivolumab and ipilimumab or with nivolumab alone in subjects with advanced/metastatic melanoma.

This is an open-label, non-randomized clinical trial study. The number of 40 COVID-19 patients with moderate severity will be admitted in progressive care units (PCUs) and intensive care units (ICUs) enrolled in the study. The sampling will be purposive and based on the same independent variables, including age, gender, past medical histories, and the situation of the patient at the admission day, and ventilator support. The patients will be allocated into two groups with different regimens. Group \"A\" (regimen A)will be defined as Favipiravir 1600 mg a first dose and 600 mg in 3 divided doses daily plus 400 mg in 2 divided doses of Hydroxychloroquine every day. The group \"B\" (regimen B) will be contained 400 mg of Lopinavir/Ritonavirin 2 divided doses plus the first dose (400 mg) of Hydroxychloroquine. Hydroxychloroquine will not be used for adverse drug reactions. The regimen remained at least 7 up to 10 days.
Data will be analyzed using statistical package for social sciences (SPSS) version 18 (SPSS Inc. Chicago, IL, USA) for windows. The variables will be compared using independent and paired T-test for normally distributed variables and Wilcoxon, Chi-square for non-normal distributed variables. The Kaplan Meier test will be used for survival analysis and the one-sample Kolmogorov-Smirnov test for the evaluation of distributions.

The current outbreak of COVID-19 caused by SARS-CoV-2 is a global health emergency with a case fatality rate so far approximately 4% and a growing number of confirmed cases (\>9500) in Germany. There is no data available on the efficacy of antiviral agents for the treatment of COVID-19. In vitro data show that hydroxychloroquine can inhibit SARS-CoV-2 replication and anecdotal reports from COVID-19 patients in China and France suggest that chloroquine or hydroxychloroquine is a good candidate for treatment. In the French study a favourable effect was seen when hydroxychloroquine was used together with azithromycin in a small series of COVID-19 patients. However, so far all published evidence is based on non-controlled use of hydroxychloroquine.
We propose to conduct a placebo-controlled trial in COVID-19 patients with mild to moderate disease in Germany to assess virological efficacy, tolerability and safety of hydroxychloroquine in the treatment of COVID-19. The objective of this trial is to identify an effect of hydroxychloroquine on viral clearance in vivo. This data will inform practice for the design of larger trials on clinical efficacy of hydroxychloroquine in the treatment and post-exposure prophylaxis of COVID-19.
