Chemsex/slamsex-related intoxications: A case report involving gamma-hydroxybutyrate (GHB) and 3-methylmethcathinone (3-MMC) and a review of the literature.

Chemsex and slamsex represent a serious public health concern that has to be considered by both clinical and forensic toxicologists. Indeed, such practices appear to carry a significant degree of risk, including acute intoxication. Here we report the case of the intoxication of a 31-year-old male involving 3-methylmethcathinone (3-MMC) and gamma-hydroxybutyrate (GHB) during a slamsex session. In addition, we conducted a review of further cases. The 31-year-old man was admitted to the emergency department for severe impaired consciousness following the administration of psychoactive substances during a chemsex party. The detection and determination of 3-MMC and GHB concentrations were achieved using liquid chromatography-tandem mass spectrometry. 3-MMC and GHB blood concentrations were 177 ng/mL and 131 mg/L, respectively. Further, an English and French exhaustive literature search was performed using several different electronic databases without any limiting period in order to identify all published case reports detailing chemsex/slamsex-related (fatal and nonfatal) intoxications. Nine publications detailing chemsex/slamsex-related intoxication cases have been published (between 2016 and 2020). These articles reported an overall of 13 cases, all involving men with a mean age of 39.1±9.8 years. The outcome was fatal in only 6 cases. 4-MEC and GHB were the two predominant drugs identified. However, given the rapid emergence of novel NPSs in the global market as well as the ease with which they can be accessed through the Internet, toxicological laboratories have to be ready to face new patterns of intoxications resulting from chemsex/slamsex.

Hydroxychloroquine in mild-to-moderate coronavirus disease 2019: a placebo-controlled double blind trial.

OBJECTIVES: To determine whether hydroxychloroquine decreases the risk of adverse outcome in patients with mild to moderate coronavirus disease 2019 (COVID-19) at high risk of worsening. METHODS: We conducted a multicentre randomized double-blind placebo-controlled trial evaluating hydroxychloroquine in COVID-19 patients with at least one of the following risk factors for worsening: need for supplemental oxygen, age ≥75 years, age between 60 and 74 years and presence of at least one co-morbidity. Severely ill patients requiring oxygen therapy >3 L/min or intensive care were excluded. Eligible patients were randomized in a 1:1 ratio to receive either 800 mg hydroxychloroquine on day 0 followed by 400 mg per day for 8 days or a placebo. The primary end point was a composite of death or start of invasive mechanical ventilation within 14 days following randomization. Secondary end points included mortality and clinical evolution at days 14 and 28, and viral shedding at days 5 and 10. RESULTS: The trial was stopped after 250 patients were included because of a slowing down of the pandemic in France. The intention-to-treat population comprised 123 and 124 patients in the placebo and hydroxychloroquine groups, respectively. The median age was 77 years (interquartile range 58-86 years) and 151/250 (60.4%) patients required oxygen therapy. The primary end point occurred in 9/124 (7.3%) patients in the hydroxychloroquine group and 8/123 (6.5%) patients in the placebo group (relative risk 1.12; 95% CI 0.45-2.80). The rates of positive SARS-CoV-2 RT-PCR tests at days 5 and 10 were 72.8% (75/103) and 57.1% (52/91) in the hydroxychloroquine group, versus 73.0% (73/100) and 56.6% (47/83) in the placebo group, respectively. No difference was observed between the two groups in any of the other secondary end points. CONCLUSION: In this underpowered trial involving mainly older patients with mild to moderate COVID-19, patients treated with hydroxychloroquine did not experience better clinical or virological outcomes than those receiving the placebo.
