Objective: To evaluatre the risk of immunogenicity in patients with chronic inflammatory diseases who experienced successive non-medical swiches to different biosimilars infliximab.

Patients And Methods: Observational study over a 3-year observation period assessing the risk of immunogenicity in i) patients in maintenance therapy with innovator infliximab who were successively switched to CT-P13, then to SB2 (cohort-1) and ii) biologic-naive patients initiated with CT-P13 before being switched to SB2 (cohort-2). A propotion meta-analysis was also performed, integrating our results to 16 additional studies.

Article Synopsis
  • - The study evaluated the effectiveness of switching from innovator infliximab to its biosimilar in adult patients at Cochin University Hospital, measuring retention rates after three infusions and examining associated factors.
  • - Out of 260 patients, an 85% retention rate for the biosimilar was noted, but 23% (59 patients) eventually discontinued due to inefficacy, with no serious side effects reported.
  • - Overall, objective disease activity measures showed no significant changes post-switch, although some subjective outcomes, particularly in patients with axial spondyloarthritis, indicated a slight increase, suggesting potential attribution effects rather than actual efficacy changes.

Faecal microbiota transplantation is effective for treating recurrent forms of Clostridium difficile infection and its use in this indication is recommended in the most recent European and North American guidelines. In this context, faecal microbiota transplantation is beginning to be performed in France in clinical practice, while the rules governing this procedure have been defined in France only for clinical trials. To unify, secure, and evaluate practice in this field in France, the French Group of Faecal microbiota Transplantation (FGFT) was created in October 2014 with the support of the French National Society of Gastroenterology, the French Infectious Disease Society, and the National Academy of Pharmacy.

Purpose: To evaluate the effect of spironolactone, a mineralocorticoid receptor antagonist, for nonresolving central serous chorioretinopathy.

Methods: This is a prospective, randomized, double-blinded, placebo-controlled crossover study. Sixteen eyes of 16 patients with central serous chorioretinopathy and persistent subretinal fluid (SRF) for at least 3 months were enrolled.

Background And Objectives: Obesity and opioid use for chronic pain in obese individuals are both important public health concerns. The pharmacokinetics of oral morphine after Roux-en-Y gastric bypass (RYGB) are unknown. Therefore, we aimed to study the pharmacokinetics of oral morphine in morbidly obese patients before and after RYGB surgery, to identify the effects of RYGB and the subsequent reversal of morbid obesity on the pharmacokinetic parameters of morphine.

Purpose: The objective of this study was to develop a population pharmacokinetic model and investigate the effect of several demographic covariates on metformin pharmacokinetics in patients with type 2 diabetes mellitus, over a wide range of weights.

Methods: A total of 105 patients received different metformin regimens, and pharmacokinetic sampling included a minimum of two concentrations per patient. Plasma determination of metformin was assayed by high performance liquid chromatography.

Theriaca, after the Greco-Roman antiquity, survived centuries with some continuity. The formula used during the 17th century, inherited from the tradition of Hippocrates and Galen is closed to what it was centuries earlier, despite the difficulties of supply of raw materials. It is considered a mainstay of therapy by the apothecaries of the 16th century as Houel or Bauderon and 17th as Charas or Lemery.

History of pharmacology intermingled with the history of poisons. The main alkaloids were discovered between 1817 and 1860. In 1845 purchase and sell of poisons were regulated and in 1884 cocaine appeared on the market and heroin in 1898.

Apollinaire Bouchardat (1806-1886) begins its hospital formation by the pharmacy internship and then starts his medical studies. He becomes chief pharmacist of the Hôtel-Dieu in 1835 and during 20 years, he devotes his life to the study of diabetes. Through observations and experiments, he builds new concepts allowing to establish the bases of clinical diabetology due to a solid competence in fundamental sciences and his intelligence in semiologic observations.

Introduction: Methadone, the most widely delivered maintenance therapy for heroin addicts, may be responsible for life-threatening poisonings with respiratory depression. The toxicokinetics and the toxicokinetic/toxicodynamic (TK/TD) relationships of methadone enantiomers have been poorly investigated in acute poisonings. The aim of this study was to describe the relationships between methadone-related respiratory effects and their corresponding concentrations.

Born from growing organic chemistry laboratories, dyes were extensively used par textile industry before to be applied in field of biology and therapeutics. Besides their interest for diagnostic techniques due to cell visualization (Virchow, Papanicolaou), dyes allowed scientists to propose scientific hypothesis founding, in conjunction with new microscopy tools, modern basis for biology : tissue constitution, cellular and sub cellular structure, s.o.

Medication errors can lead to treatment failure and adverse drug reactions with potentially life-threatening consequences, especially when the patient is fragile or the drug is highly toxic. Both these latter factors are frequent in the cancer setting. Computers can be used to securitize the prescription (through validated protocols), preparation and administration of anticancer drugs, including experimental drugs, as they can store a wealth of information on both the individual patient and the product.
