[A man with unilateral erythema of the leg]. / Een man met een rood been.

We report the case of an otherwise healthy 47 year-old man who presented to the dermatology outpatient clinic with asymptomatic, one sided erythema of his leg, without edema. The diagnosis acrodermatitis chronica atrophicans was made based on positive IgG antibodies to Borrelia burgdorferi.

Tralokinumab treatment for patients with moderate-to-severe atopic dermatitis in daily practice.

BACKGROUND: Evidence about tralokinumab treatment for moderate-to-severe atopic dermatitis (AD) in daily practice is limited. AIM: To report the first evidence, to our knowledge, from daily practice of treatment with tralokinumab in patients with AD. METHODS: In this observational prospective study, patients with AD who received tralokinumab treatment in the context of routine care at the Erasmus Medical Centre were included between November 2021 and February 2022. This included 28 patients who had previously been treated with dupilumab, and 14 patients who had been treated with a Janus kinase inhibitor (JAKi). The Investigator's Global Assessment (IGA; 0-4) and the numeric rating scale peak pruritus during the past 7 days (NRS itch 7d: 0-10), adverse events and reasons for discontinuation were analysed. A good clinical response was defined as any decrease in IGA and NRS itch 7d and if a patient was satisfied with the treatment and wished to continue with therapy. RESULTS: In total, 37 patients were treated with tralokinumab. Twenty-two (59%) patients showed a good response to tralokinumab treatment. Fifteen (41%) patients discontinued treatment because of inadequate AD control or adverse events. Treatment-related adverse events were mild in most patients. Half of the patients where treatment with dupilumab had failed had a good clinical response to tralokinumab. CONCLUSIONS: Tralokinumab was found to be effective in most patients in this cohort with difficult-to-treat, severe AD from daily practice. Interestingly, tralokinumab was also found to be effective in 50% of patients who had previously experienced insufficient response or adverse events with dupilumab treatment.

The impact of implementing the WHO-2013 criteria for gestational diabetes mellitus on its prevalence and pregnancy outcomes: A comparison of the WHO-1999 and WHO-2013 diagnostic thresholds.

AIMS/HYPOTHESIS: To determine the impact of implementing the new WHO-2013 criteria on prevalence of gestational diabetes mellitus (GDM) and pregnancy outcomes compared to the WHO-1999 criteria. METHODS: A retrospective study conducted in pregnant women who were referred to the Erasmus MC for an oral glucose tolerance test (OGTT) between 2010 and 2015. RESULTS: Of 3089 women, 11.5 % (n = 354) were diagnosed with GDM based on the WHO-1999 criteria and 17.0 % (n = 524) based on the 2013-criteria, with 97 (3.1 %) reclassified as non-GDM and 267 (8.6 %) reclassified as GDM when shifting from the 1999 to 2013-criteria. In contrast to 60 % of patients in the WHO-2013 group, only 2 % of the WHO-1999 group was diagnosed with GDM because of an elevated fasting glucose only. Patients reclassified as GDM by WHO-2013 criteria had a higher body mass index (p < 0.001) and delivered babies with a higher birth weight (p = 0.01). Maternal and neonatal adverse outcomes were comparable between patients with GDM based on WHO-1999 criteria and patients newly included by WHO-2013 criteria. CONCLUSIONS: Implementing the new diagnostic criteria leads to a considerable increase of prevalence of GDM. The newly included patients were more frequently overweighed and delivered babies with a higher birth weight. The added diagnostic value of the fasting glucose threshold of the WHO-1999 criteria is very low compared to the 2-h post-OGTT threshold, supporting the use of a lower fasting glucose threshold value as advocated by the WHO-2013 criteria. TWEET: The new WHO-2013 criteria leads to a considerable increase of prevalence of GDM.
