Abstract

Abstract Substantial COVID-19 research investment has been allocated to randomized clinical trials (RCTs) on hydroxychloroquine/chloroquine, which currently face recruitment challenges or early discontinuation. We aim to estimate the effects of hydroxychloroquine and chloroquine on survival in COVID-19 from all currently available RCT evidence, published and unpublished. We present a rapid meta-analysis of ongoing, completed, or discontinued RCTs on hydroxychloroquine or chloroquine treatment for any COVID-19 patients (protocol: https://osf.io/QESV4/ ). We systematically identified unpublished RCTs (ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Cochrane COVID-registry up to June 11, 2020), and published RCTs (PubMed, medRxiv and bioRxiv up to October 16, 2020). All-cause mortality has been extracted (publications/preprints) or requested from investigators and combined in random-effects meta-analyses, calculating odds ratios (ORs) with 95% confidence intervals (CIs), separately for hydroxychloroquine and chloroquine. Prespecified subgroup analyses include patient setting, diagnostic confirmation, control type, and publication status. Sixty-three trials were potentially eligible. We included 14 unpublished trials (1308 patients) and 14 publications/preprints (9011 patients). Results for hydroxychloroquine are dominated by RECOVERY and WHO SOLIDARITY, two highly pragmatic trials, which employed relatively high doses and included 4716 and 1853 patients, respectively (67% of the total sample size). The combined OR on all-cause mortality for hydroxychloroquine is 1.11 (95% CI: 1.02, 1.20; I² = 0%; 26 trials; 10,012 patients) and for chloroquine 1.77 (95%CI: 0.15, 21.13, I² = 0%; 4 trials; 307 patients). We identified no subgroup effects. We found that treatment with hydroxychloroquine is associated with increased mortality in COVID-19 patients, and there is no benefit of chloroquine. Findings have unclear generalizability to outpatients, children, pregnant women, and people with comorbidities.

Abstract

Background: Early recurrence of Plasmodium vivax is a challenge for malaria control in the field, particularly because this species is associated with lower parasitemia, which hinders diagnosis and monitoring through blood smear testing. Early recurrences, defined as the persistence of parasites in the peripheral blood despite adequate drug dosages, may arise from resistance to chloroquine. The objective of the study was to estimate early recurrence of P. vivax in the Brazilian Amazon by using a highly-sensitive detection method, in this case, PCR. Methods: An ultra-sensitive qPCR that targeted mitochondrial DNA was used to compare a standard qPCR that targeted 18S rDNA to detect early recurrence of P. vivax in very low densities in samples from patients treated with chloroquine. Results: Out of a total of 312 cases, 29 samples (9.3%) were characterized as recurrences, from which 3.2% (10/312) were only detected through ultra-sensitive qPCR testing. Conclusions: Studies that report the detection of P. vivax early recurrences using light microscopy may severely underestimate their true incidence.

Abstract

Anopheles aquasalisis a primary malaria vector in coastal South America that grows in brackish waters of mangroves. Its importance has increased in recent years as it has been established as a model for parasite-vector studies for non-modelPlasmodiumspecies, such asP. yoelli. In this study, we present the complete genome ofAn. aquasalisand offer some insights into evolution and physiology. With a 162Mb and 12,446 coding proteins, theAn. aquasalisgenome is similar in size and gene content as other neotropical anophelines. 1,038 single-copy orthologs are present inAn. aquasalisand all Diptera and it was possible to infer thatAn. aquasalisdiverged fromAn. darlingi(the main malaria vector in inland South America) nearly 14 million years ago (mya). Ion transport and metabolism proteins is one the major gene families inAn. aquasaliswith 660 genes. Amongst these genes, important gene families relevant for osmosis control (e.g., aquaporins, vacuolar-ATPases, Na+/K+-ATPases and carbonic anhydrases) were identified in one-to-one orthologs with other anophelines. Evolutionary analysis suggests that all osmotic regulation genes are under strong purifying selection. We also observed low copy number variation in immunity-related genes (for which all classical pathways were described) and insecticide resistance genes. This is the third genome of a neotropical anopheline published so far. The data provided by this study may offer candidate genes for further studies on parasite-vector interactions and for studies on how brackish water anophelines deals with high fluctuation in water salinity.Significance StatementThe brackish water mosquitoAnopheles aquasalisis a primary malaria vector in coastal South America. Besides its peculiar ecological features (it is one of the few anopheline mosquitoes that survives high fluctuation of water salinity),An. aquasalishas gained relevance in recent years as a model for parasite-vector studies for non-modelPlasmodiumparasites. Still, the physiology and genetics ofAn. aquasalisare poorly understood. Here we present the genome ofAn. aquasaliswith more than 12,000 annotated genes, offering insights in genome evolution, osmoregulation related, immunity, chemosensory and insecticide resistance genes. The data presented here will help to further advance the studies onAn. aquasalisgenetics and physiology to better understand parasite-vector interactions in non-model organisms.
