The Lancet Doubles Down on anti-HCQ Fraud

The Lancet doubled down on its previous smear of Hydroxychloroquine (Mehra et al.), the main component of an effective COVID-19 treatment. On July 9, the Lancet published

Retraction and republication: cardiac toxicity of hydroxychloroquine in COVID-19

Christian Funck-Brentano, Lee S Nguyen, Joe-Elie Salem

Notice that two of the three authors (Funck-Brentano and Salem) were also authors of the op-ed or comment to Mehra et al., published on the same day, which was also retracted.

This latest article re-uses the debunked Magagnoli et al., Rosenberg et al., and the tragicomic RECOVERY trial. In addition, it relies on an earlier fraudulent paper from the same authors Nguyen et al. (with additional co-authors). Coincidentally, it was published on the same day as Mehra et al.

Cardiovascular Toxicities Associated with Hydroxychloroquine and Azithromycin: An Analysis of the World Health Organization Pharmacovigilance Database

This is another example of “database studies”. It uses fake methodology, described in gibberish. This is an excerpt from the methods (self-references are omitted):

 Association between hydroxychloroquine, azithromycin, and their combination with CV-ADR was assessed using reporting-odds-ratio (ROR) and information component (IC), an indicator value for disproportionate Bayesian reporting that compares observed and expected values to find associations between drugs and ADR. The lower end of the IC’s 95% credibility interval is IC025. It is considered significant when above 0.

ROR and IC are BS. The authors made up these quantities. The data is extracted from WHO’s VigiBase, using VigiAccess interface (Vigi– comes from vigilance. Its description can be found in https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5051262/). VigiBase is similar to FDA’s FAERS, containing mostly unverified reports of adverse effects, possibly linked to the drug. In addition, it contains complaints about the drugs’ effectiveness and even administration procedures.

The number of records in this database has little relation to the drug’s safety.  For comparison, on July 13 there were the following number of adverse reports for each of the following drugs:

Paracetamol: 151, 575

Ibuprofen: 147,755

Azithromycin: 59,190

Hydroxychloroquine: 25,719

These numbers represent unverified reports, not adjudicated cases. For HCQ, the largest group category of concern was “General disorders and administration site conditions” (accounting for 10422 of the reports); the largest subcategory of concern was “Drug ineffective” (accounting for 6182 of the reports).

The authors claim that they have found “76,822 ADR cases associated with hydroxychloroquine alone” – this number is significantly higher than actual non-duplicate records. In less than 500 of these cases, HCQ was associated with cardiovascular adverse reactions. Hydroxychloroquine with Azithromycin were suspected in only 9 (nine) cases.

This paper contains no abstract and no subsections. Its only coherent conclusion, “Hydroxychloroquine was also associated with potentially lethal HF [heart failure] when exposure was prolonged over several months“, is neither relevant for a 5-day treatment needed for COVID-19, nor in agreement with other literature on the subject. Another oddity of this paper is that it has only five references, three of which are self-references (i.e., references to papers including at least one of the same authors).  Most papers have dozens of references to the work of many other scientists who have come to the same conclusions.

As expected, the authors have hidden conflicts of interest. Christian Funck-Brentano is a Scientific Advisor to Banook Group (http://www.banookgroup.com/ap/webinar/). The Banook Group (formerly Cardiabase)  offers services in the field of cardiac safety (https://www.banookgroup.com/for-all/solutions/cardiac-safety/).

RECOVERY TRIAL

A huge clinical trial RECOVERY, conducted in the Britain, would be comical if it were not so tragic. The clinical researchers confused HCQ with another drug and consequently gave their patients 6x the dose normally recommended (2,400 mg/day instead of 400 mg/day). Even at this exorbitant dosage, the drug was tolerated well.

CQ/HCQ Cardiac Safety

In 2017, WHO investigated suspicions of cardiotoxicity of various anti-malarial drugs. It found CQ and HCQ to be exceptionally safe. Out of hundreds of millions of doses, only 11 deaths were reportedly in association with CQ or HCQ, four of which were clearly shown to be overdoses.

Exposure to chloroquine and hydroxychloroquine was reported in six and five cases of sudden death, respectively. In four of these cases, overdose was listed as the indication. Hydroxychloroquine was used to treat rheumatoid arthritis, systemic lupus erythematosus and small cell lung carcinoma in one case each.

Despite hundreds of millions of doses administered in the treatment of malaria, there have been no reports of sudden unexplained death associated with quinine, chloroquine or amodiaquine, although each drug causes QT/QTc interval prolongation.
