Rivaroxaban (Xarelto®): Update on new clinical data and therapeutic perspectives

Cédric Hermans Published in the journal : October 2020 Category : Actualité thérapeutique

Direct oral anticoagulants (AODs), which target coagulation Factors Xa or IIa, represent a major therapeutic innovation. Even if classical anticoagulants, such as vitamin K antagonists (AVK) and low molecular weight heparins, still play a crucial role in preventive or curative treatment, AODs have revolutionized the medical management of thrombotic diseases, concerning both arterial and venous conditions.

In addition to being able to replace conventional anticoagulants in common indications like atrial fibrillation and venous thromboembolic disease, there is a plethora of Xarelto data from recent and original studies, as well as from registries and Phase III sub-analyses, which are currently revolutionizing the modalities and benefits of oral anticoagulation at all stages of life and in a wide spectrum of indications.

This article provides a synthetic and practical review of these data and their therapeutic implications.

Semaglutide (Ozempic®), a new weekly GLP- 1 analogue for the treatment of type 2 diabetes mellitus

Michel P. Hermans Published in the journal : July 2019 Category : Actualité thérapeutique

Semaglutide is a GLP-1 analogue recently marketed in Belgium for the treatment of hyperglycaemia in patients with type 2 diabetes, by weekly subcutaneous administration. Among GLP-1 receptor agonists, semaglutide, at a maintenance dose of 0.5 or 1.0 mg/week, is currently the most effective compound for reducing chronic hyperglycaemia and body weight, as monotherapy or in combination with other hypoglycaemic medications, including basal insulin. The SUSTAIN 6 study also suggests a clinical benefit at the cardiovascular level. The tolerance and safety of semaglutide are comparable to those of other GLP-1 receptor agonists currently available in Belgium

Biotherapies in the management of moderate-to-severe psoriasis

Deborah Debois, Marie Baeck, Pierre-Dominique Ghislain (1) Published in the journal : May 2019 Category : Actualité thérapeutique

Psoriasis, a very common systemic inflammatory disease, is potentially disabling from a functional and aesthetic point of view. In recent years, treatments for managing moderate- to-severe psoriasis have significantly evolved since the advent of biologic therapies. Undoubtedly, these latter have favorably impacted the patient quality of life.

Degludec (Tresiba®): a new ultra-long acting basal insulin analog

Michel P. Hermans, Vanessa Preumont (1) Published in the journal : May 2019 Category : Actualité thérapeutique

Insulin degludec (Tresiba®) is an ultra-long acting basal insulin analog recently marketed in Belgium. Controlled clinical trials have demonstrated that insulin degludec provides similar reductions in HbA1c compared to the basal analogs glargine or detemir in Type 1 and Type 2 diabetes, with superior fasting glucose control in the majority of studies. The data additionally show a clinically relevant reduction in the incidence of hypoglycemia episodes, especially at night. The results of controlled and observational studies point towards the therapeutic added value of degludec in the management of Type 1 and Type 2 diabetes.

Canagliflozin (Invokana®) associated with exemplary nephro- and cardioprotection in Type 2 diabetes. Synopsis of the CREDENCE study

Martin Buysschaert Published in the journal : May 2019 Category : Actualité thérapeutique

The CREDENCE study sought to compare the efficacy of canagliflozin vs. placebo in preventing clinically-relevant kidney and cardiovascular events in patients with diabetes and established kidney disease. With regard to the primary endpoint (terminal kidney failure; doubling of creatinine; renal or cardiovascular death), the authors reported a 30% reduction in the relative risk (hazard ratio [HR]: 0.70; 95% CI: 0.59-0.82, p=0.00001) after 2.6 years of follow-up. The risk was reduced by 17-39% with regard to secondary cardiovascular or renal endpoints. These results should be integrated in our therapeutic approach for Type 2 diabetes patients, in terms of both nephro- and cardioprotection.

Direct Oral Anticoagulants : recommendations for the general practitioner

Cédric Hermans Published in the journal : October 2018 Category : Actualité thérapeutique

Direct oral anticoagulants (DOACs) represent one of the greatest therapeutic innovations of the last decades. Their effectiveness and safety have been clearly demonstrated in a large number of indications. The main precautions for use have been identified. While initially limited to specialists, the prescription of DOACs is now part of the daily practice of many general practitioners. This article reviews, in a concise and practical way, some essential information about DOACs that are useful for any general practitioner.

Rational use of antibiotics in adults in general practice – from the right diagnosis to the right treatment duration

Sophie Paternostre (1), Leila Belkhir (1), Jean-Cyr Yombi (1) Published in the journal : October 2018 Category : Actualité thérapeutique

Respiratory, urinary, and cutaneous infections make up a significant proportion of general practice consultations. Few new antibiotics are available on the market and given the increase of multiresistant bacteria, a rational use of antibiotics proves necessary. Rhinopharyngitis, rhinosinusitis, and bronchitis are most often of viral origin, and treatment is therefore symptomatic. Antibiotics are only required in case of suspected bacterial superinfection, in which case treatment duration is 5 days. Among urinary tract infections, a distinction should be made between complicated and uncomplicated infections, while taking into account some specific risk factors. Both can be complicated by severe sepsis. Escherichia coli remains the predominant uropathogen. There is an increase in multiresistant bacteria, even in the community. Asymptomatic bacteriuria (AB) is common, especially among elderly people. Screening and treatment of AB are indicated only in pregnant women and patients undergoing urinary tract instrumentation with a risk of mucosal bleeding. Skin infections, such as impetigo, do not always require systemic antibiotics. This article is aimed at supplementing and updating the data of an article on the rational use of antibiotics in general medicine published in 2015 in the same journal. It additionally includes recent data on the management of pneumonia, pertussis, and skin infections.

PCSK9 inhibitors in therapeutic arsenal of cardiovascular risk management

Olivier S. Descamps Published in the journal : October 2018 Category : Actualité thérapeutique

In clinical practice, it may at times prove difficult to attain the recommended LDL cholesterol levels due to either high initial levels or low drug tolerance. The 2003 discovery of a new protein named PCSK9 (proprotein convertase subtilisin/kexine Type 9), involved in the metabolism of LDL particles, led to the development of several monoclonal antibodies that neutralize this protein (evolocumab from Amgen, alirocumab from Sanofi/REGENERON, and bocozicumab from Pfizer). When combined with statins and ezetimibe, these agents cause a highly significant reduction in LDL cholesterol levels, associated with very good safety profiles and tolerance, along with significant benefits in terms of cardiovascular prevention. Therefore, they constitute an additional therapeutic strategy to help patients reach their LDL cholesterol targets, especially those with severely elevated cholesterol levels, as observed in familial hypercholesterolemia cases.
