Both rifampicin and plasmapheresis represent important therapeutic options of acute cholestatic attacks in patients with BRIC. As a noninvasive treatment, rifampicin may be the first choice.

Background The carnitine precursor trimethyllysine (TML) is associated with progression of atherosclerosis, possibly through a relationship with trimethylamine‐N‐oxide (TMAO). Riboflavin is a cofactor in TMAO synthesis. We examined prospective relationships of circulating TML and TMAO with acute myocardial infarction (AMI) and potential effect modifications by riboflavin status. Methods By Cox modelling, risk associations were examined amongst 4098 patients (71.8% men) with suspected stable angina pectoris. Subgroup analyses were performed according to median plasma riboflavin. Results During a median follow‐up of 4.9 years, 336 (8.2%) patients experienced an AMI. The age‐ and sex‐adjusted hazard ratio (HR) (95% CI) comparing the 4th vs. 1st TML quartile was 2.19 (1.56–3.09). Multivariable adjustment for traditional cardiovascular risk factors and indices of renal function only slightly attenuated the risk estimates [HR (95% CI) 1.79 (1.23–2.59)], which were particularly strong amongst patients with riboflavin levels above the median (Pint = 0.035). Plasma TML and TMAO were strongly correlated (rs = 0.41; P < 0.001); however, plasma TMAO was not associated with AMI risk in adjusted analyses [HR (95% CI) 0.81 (0.58–1.14)]. No interaction between TML and TMAO was observed. Conclusion Amongst patients with suspected stable angina pectoris, plasma TML, but not TMAO, independently predicted risk of AMI. Our results motivate further research on metabolic processes determining TML levels and their potential associations with cardiovascular disease. We did not adjust for multiple comparisons, and the subgroup analyses should be interpreted with caution.

Background Paediatric atopic dermatitis (AD) can be burdensome, affecting mental health and impairing quality of life for children and caregivers. Comprehensive guidelines exist for managing paediatric AD, but practical guidance on using systemic therapy is limited, particularly for new therapies including biologics and Janus kinase (JAK) inhibitors, recently approved for various ages in this indication. Objectives This expert consensus aimed to provide practical recommendations within this advancing field to enhance clinical decision‐making on the use of these and other systemics for children and adolescents aged ≥2 years with moderate‐to‐severe AD. Methods Nineteen physicians from Northern Europe were selected for their expertise in managing childhood AD. Using a two‐round Delphi process, they reached full or partial consensus on 37 statements. Results Systemic therapy is recommended for children aged ≥2 years with a clear clinical diagnosis of severe AD and persistent disease uncontrolled after optimizing non‐systemic therapy. Systemic therapy should achieve long‐term disease control and reduce short‐term interventions. Recommended are cyclosporine A for short‐term use (all ages) and dupilumab or methotrexate for long‐term use (ages ≥6 years). Consensus was not reached on the best long‐term systemics for children aged 2–6 years, although new systemic therapies will likely become favourable: New biologics and JAK inhibitors will soon be approved for this age group, and more trial and real‐world data will become available. Conclusions This article makes practical recommendations on the use of systemic AD treatments for children and adolescents, to supplement international and regional guidelines. It considers the systemic medication that was available for children and adolescents with moderate‐to‐severe AD at the time this consensus project was done: azathioprine, cyclosporine A, dupilumab, methotrexate, mycophenolate mofetil and oral glucocorticosteroids. We focus on the geographically similar Northern European countries, whose healthcare systems, local preferences for AD management and reimbursement structures nonetheless differ significantly.
