Aim: The mechanism of MDMA (3,4-methylenedioxymethamphetamine)-induced toxicity is believed to be, in part, due to enhanced oxidative stress. As MDMA is eliminated via the kidney, the aim of this study was to investigate whether MDMA created conditions of oxidative stress within rat kidney.
Methods: Adult male Wistar rats were divided into three groups, control treatment (water), acute MDMA administration (single oral dose: 5, 10, 20 or 40 mg/kg body weight) and subacute MDMA administration (5, 10, or 20 mg/kg body weight per day during 14 days). Animals were sacrificed 8 h after the single oral MDMA administration in the acute MDMA administration group and after the last MDMA administration in the subacute MDMA administration group. Rectal temperature measurements, oxidative stress status parameters and histological examinations were performed.
Results: In all MDMA-administered rats, rectal temperature markedly increased peaking approximately 1 h after MDMA ingestion. Superoxide dismutase activity and thiobarbituric acid reactive substances increased after MDMA administration. Histological examinations of the kidney revealed dose-dependent disruption of tissue structure in subacute MDMA-administered rats. The latter was not observed in acute MDMA-administered rats.

Importance: There is unprecedented clinician, industry, and patient interest in the therapeutic development of psychedelic drugs. This is due to a combination of promising clinical trial results, positive media coverage, and the lack of novel pharmacologic treatments for psychiatric disorders in recent decades. However, the field faces a key methodological challenge: masking participants to treatment conditions in psychedelic clinical trials has been largely unsuccessful.

The guidelines from the European and American Societies for Gastrointestinal Endoscopy discourage endoscopic retrieval of drug bags in body stuffers. However, recent evidence challenges this stance, demonstrating successful bag retrieval without fatal outcomes. We present two distinct cases illustrating varying outcomes of intervention.

The recent rejection of 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy by the U.S. Food and Drug Administration (FDA) is a dramatic moment in the re-emergence of psychedelic research.
