Castleman disease is a rare disorder that involves an overgrowth (proliferation) of cells in your body's disease-fighting network (lymphatic system). Also known as giant lymph node hyperplasia and angiofollicular lymph node hyperplasia, Castleman disease can occur in a localized (unicentric) or widespread (multicentric) form.
Fever. Night sweats. Fatigue and weakness. Loss of appetite. Unintended weight loss. Enlarged lymph nodes, usually around the neck, collarbone, underarm and groin areas. Enlarged liver or spleen.
At baseline, the mean number of symptoms reported was 9.2 (standard deviation 3.76) out of 16 total, as measured by the MCD–SS. Fatigue was a key symptom across all PRO instruments. Siltuximab-treated subjects reported early improvements in symptoms compared with subjects in the placebo arm on both the MCD–SS and FACIT–Fatigue scale.
