Table 3 Serotonin uptake characteristics in platelets of control subjects and patients with fibromyalgia

From: Alteration of serotonin transporter density and activity in fibromyalgia

Variable

Controls (n = 38)

Patients with FM (n = 40)

Vmax (pmol/109 platelets per minute)

114 ± 6

90 ± 4a

Km (nM)

114 ± 15

96 ± 15

  1. Results are shown as means ± SEM. FM, fibromyalgia; Km, Michaelis constant; Vmax, maximal uptake rate of specific serotonin transporter. ap < 0.001.
