The melanocortin-4 receptor agonist setmelanotide compensates for upstream gene defects in the brain leptin-melanocortin pathway and reduces hyperphagia and obesity in selected monogenic obesity forms and Bardet-Biedl syndrome (BBS). We aimed to evaluate the short-term impact of setmelanotide treatment in BBS presenting original real-world data focusing on metabolic dysfunction-associated steatotic liver disease (MASLD) and kidney function. This monocentric, prospective observational cohort study was performed between June and December 2023 and included patients above the age of 6 years with genetically confirmed BBS, obesity, and/or hyperphagia and planned setmelanotide therapy. Ultrasound examination of the liver including shear wave elastography, dispersion and attenuation imaging (ATI), a bioimpedance analysis, and a hyperphagia questionnaire survey were applied in addition to clinical data collection. Twenty-six patients with BBS (mean age 19.2 years, range [6.2; 51.8]; mean body mass index (BMI) z-score 2.95, range [1.32; 4.84]) were included. All were classified with MASLD (54% S3, 23% each S1 and S2). After 6 months of setmelanotide treatment, estimated glomerular filtration rate increased up to 10.1 mL/min/1.73 m² (95% confidence interval (CI) [4.3; 15.9]). The following parameters also improved: BMI z-score -0.5 (95% CI [-0.6; -0.3]); hyperphagia score -12.3 (95% CI [-15.5; -9.0]); total body fat -3.1% (95% CI [-5.7; -0.5]); ATI -0.14 dB/cm/MHZ (95% CI [-0.17; -0.11]). A total of 85% of patients exhibited either resolution of MASLD or stabilization at grade S1. MASLD improvement correlated only with liver size, not BMI reduction. Setmelanotide treatment is associated with improvement of MASLD independent of BMI reduction as well as increased glomerular filtration rate in BBS. Show less

Post-COVID syndrome (PCS) is an important sequela of COVID-19, characterised by symptom persistence for >3 months, post-acute symptom development, and worsening of pre-existing comorbidities. The causes and public health impact of PCS are still unclear, not least for the lack of efficient means to assess the presence and severity of PCS. COVIDOM is a population-based cohort study of polymerase chain reaction (PCR) confirmed cases of SARS-CoV-2 infection, recruited through public health authorities in three German regions (Kiel, Berlin, Würzburg) between November 15, 2020 and September 29, 2021. Main inclusion criteria were (i) a PCR confirmed SARS-CoV-2 infection and (ii) a period of at least 6 months between the infection and the visit to the COVIDOM study site. Other inclusion criteria were written informed consent and age ≥18 years. Key exclusion criterion was an acute reinfection with SARS-CoV-2. Study site visits included standardised interviews, in-depth examination, and biomaterial procurement. In sub-cohort Kiel-I, a PCS (severity) score was developed based upon 12 long-term symptom complexes. Two validation sub-cohorts (Würzburg/Berlin, Kiel-II) were used for PCS score replication and identification of clinically meaningful predictors. This study is registered at clinicaltrials.gov (NCT04679584) and at the German Registry for Clinical Studies (DRKS, DRKS00023742). In Kiel-I ( PCS severity can be quantified by an easy-to-use symptom-based score reflecting acute phase disease burden and general psychological predisposition. The PCS score thus holds promise to facilitate the clinical diagnosis of PCS, scientific studies of its natural course, and the development of therapeutic interventions. The COVIDOM study is funded by the Network University Medicine (NUM) as part of the National Pandemic Cohort Network (NAPKON). Show less
