Nouvelles armes thérapeutiques contre le mélanome de stade IV [New therapeutic weapons in stage IV melanoma].

The treatment of stage IV melanoma has been revolutionized over the last years with the development of immunotherapies that, for the first time, have shown a significant benefit in overall survival, as well as with extremely effective targeted therapies, that also led to improved survival. These results are the fruits of an important translational research effort that allowed a rational approach with a very fast clinical development. The treatment of metastatic melanoma is, therefore, an illustration of the new paradigms of modern molecular research in oncology. In this review, we will present the various agents that have made the proof of their clinical benefit, as well as the scientific discoveries that allowed their development. Some of the remaining questions will be touched upon with the ongoing clinical trials. Inclusion of patients in these studies remains the top priority to improve on the clinical care.

Targeting Toll-Like Receptors: Promising Therapeutic Strategies for the Management of Sepsis-Associated Pathology and Infectious Diseases.

Toll-like receptors (TLRs) are pattern recognition receptors playing a fundamental role in sensing microbial invasion and initiating innate and adaptive immune responses. TLRs are also triggered by danger signals released by injured or stressed cells during sepsis. Here we focus on studies developing TLR agonists and antagonists for the treatment of infectious diseases and sepsis. Positioned at the cell surface, TLR4 is essential for sensing lipopolysaccharide of Gram-negative bacteria, TLR2 is involved in the recognition of a large panel of microbial ligands, while TLR5 recognizes flagellin. Endosomal TLR3, TLR7, TLR8, TLR9 are specialized in the sensing of nucleic acids produced notably during viral infections. TLR4 and TLR2 are favorite targets for developing anti-sepsis drugs, and antagonistic compounds have shown efficient protection from septic shock in pre-clinical models. Results from clinical trials evaluating anti-TLR4 and anti-TLR2 approaches are presented, discussing the challenges of study design in sepsis and future exploitation of these agents in infectious diseases. We also report results from studies suggesting that the TLR5 agonist flagellin may protect from infections of the gastrointestinal tract and that agonists of endosomal TLRs are very promising for treating chronic viral infections. Altogether, TLR-targeted therapies have a strong potential for prevention and intervention in infectious diseases, notably sepsis.

Therapeutic concepts in adult and paediatric eosinophilic oesophagitis.

Eosinophilic oesophagitis (EoE) was first described in the early 1990s. Although initially reported to be a rare entity, EoE has rapidly become a regularly diagnosed disease with a prevalence of approximately 1 in 2,000 individuals in the USA and Europe. The disease is characterized by a combination of oesophageal dysfunction and predominant eosinophilic infiltration of the oesophageal tissue. At diagnosis, other diseases that can be associated with oesophageal eosinophilic infiltration must be ruled out. Children with EoE present with a wide variety of symptoms, whereas adults mostly present with dysphagia for solid food and chest pain. Histologic features of EoE resemble those of T-helper type 2 inflammation. Endoscopy should be carried out to establish the diagnosis, but endoscopic abnormalities are not pathognomonic for EoE and the examination might not show histologic abnormality. Treatment modalities for EoE include drugs (corticosteroids, PPIs, antiallergic and biologic agents), hypoallergenic diets and oesophageal dilatation for strictures that are unresponsive to medical therapy. Unresolved eosinophilic inflammation leads to the formation of oesophageal strictures, which probably increase the risk of food bolus impactions. To date, long-term strategies for the therapeutic management of this chronic inflammatory disease remain poorly defined.

Nouvelles approches therapeutiques de l'hypertension arterielle. [New therapeutic approaches to arterial hypertension]

Today two largely new approaches are available for the treatment of clinical hypertension. First, captopril, an orally active angiotensin converting enzyme inhibitor, makes possible chronic blockade of the renin-angiotensin system. This compound, given alone or in combination with a diuretic, normalizes the blood pressure of most hypertensive patients. Unfortunately, because captopril may induce serious adverse effects the use of this inhibitor must be restricted to patients with high blood pressure refractory to conventional antihypertensive drugs. Second, compounds such as verapamil and nifedipine are capable of producing a marked vasodilating effect by inhibiting the entry of calcium into the vascular smooth muscle cells. However, the role of calcium channel blockers in the treatment of hypertensive disease awaits more precise definition.

Therapeutisches Drug-Monitoring in der Psychiatrie : Kurze Zusammenfassung des neuen Konsensuspapiers der Arbeitsgruppe TDM der AGNP [Therapeutic drug monitoring in psychiatry : A brief summary of the new consensus paper by the task force on TDM of the AGNP].

In October 2011 the Task Force Therapeutic Drug Monitoring of the Association for Neuropsychopharmacology and Pharmacopsychiatry (AGNP) published an update (Pharmacopsychiatry 2011, 44: 195-235) of the first version of the consensus paper on therapeutic drug monitoring (TDM) published in 2004. This article summarizes the essential statements to make them accessible to a wider readership in German speaking countries.

Analytical methods for the quantitative determination of selective serotonin reuptake inhibitors for therapeutic drug monitoring purposes in patients.

Five selective serotonin reuptake inhibitors (SSRIs) have been introduced recently: citalopram, fluoxetine, fluvoxamine, paroxetine and sertraline. Although no therapeutic window has been defined for SSRIs, in contrast to tricyclic antidepressants, analytical methods for therapeutic drug monitoring of SSRIs are useful in several instances. SSRIs differ widely in their chemical structure and in their metabolism. The fact that some of them have N-demethylated metabolites, which are also SSRIs, requires that methods be available which allow therapeutic drug monitoring of the parent compounds and of these active metabolites. most procedures are based on prepurification of the SSRIs by liquid-liquid extraction before they are submitted to separation by chromatographic procedures (high-performance liquid chromatography, gas chromatography, thin layer chromatography) and detection by various detectors (UV, fluorescence, electrochemical detector, nitrogen-phosphorus detector, mass spectrometry). This literature review shows that most methods allow quantitative determination of SSRIs in plasma, in the lower ng/ml range, and that they are, therefore, suitable for therapeutic drug monitoring purposes of this category of drugs.
