Objectives: To identify and characterize the observations of sarcoidosis occurring during anti-TNF blockade collected in the French Pharmacovigilance system database and reported in the literature.

Results: Seven cases were reported in the French Pharmacovigilance system database and 39 cases (37 original) have been reported internationally. Monoclonal antibodies (infliximab and adalimumab) and fusion protein (etanercept) are equally involved. Sarcoidosis have been confirmed histologically and occurred predominantly in the rheumatoid arthritis (22) and spondylarthropathy (16).

Conclusion: The lack of protopathic bias suggests that these paradoxical sarcoidosis occurring during treatment with anti-TNF are a class-effect, as with psoriasis, uveitis, and IBD reported under similar conditions. Their pathogenesis remains unclear.

The 2023-2024 updates on teratovigilance, with a focus on antiseizure medications, highlight several key points. American medical societies have revised their recommendations: maintaining effective seizure control is essential for both maternal and fetal health; lamotrigine, levetiracetam, and oxcarbazepine are preferred first-line treatments, whereas valproic acid and topiramate should be avoided if possible. In March 2024, an update on topiramate indicated an increased risk of neurodevelopmental disorders with prenatal exposure.

Article Synopsis
  • The study focused on identifying situations that lead to metformin-associated lactic acidosis (MALA) in ICU patients and evaluating its preventability.
  • A total of 198 MALA cases were assessed, with 19.2% resulting in death; the majority of patients had acute events like dehydration or severe infections that contributed to the condition.
  • The findings indicated that MALA is often preventable, highlighting the need for better physician and patient education regarding metformin use during high-risk medical situations.

Background: We sought to comprehensively describe drug-related components associated with acute kidney injury (AKI) in patients with chronic kidney disease (CKD), describing the incidence of drug-related AKI, the proportion of preventable AKI, identified the various drugs potentially associated with it, explored the risk factors, and assessed the 1-year incidences of the recurrence of drug-related AKI, kidney failure, and death.

Methods: CKD-REIN is a French national prospective cohort of 3033 nephrology outpatients with a confirmed diagnosis of CKD (eGFR <60 ml/min/1.73 m²).

Continuous compensation for cerebral dopamine deficiency represents an ideal treatment for Parkinson's disease. Dopamine does not cross the digestive and blood-brain barriers and is rapidly oxidized. The new concept is the intracerebroventricular administration of anaerobic dopamine (A-dopamine) using an abdominal pump connected to a subcutaneous catheter implanted in the third ventricle, near the striatum.
