Interestingly, a cross-sectional study investigated the relationship between PhA and inflammation (measured by C-reactive protein, CRP) in 15 patients with PWS (28 ± 6.8 years, 43.8 ± 10.7 kg/m2) compared to gender-, age-, and BMI- matched individuals without PWS (n = 15, 30 ± 6.9 years, 43.9 ± 8.8 kg/m2) [80]. Here, CRP is linked to Prader-Willi syndrome.
