Long term outcome of patients with low level of cryoglobulin (<Â 0.05Â g/L)

Our study shows a high prevalence of cryoglobulin level ≤ 0.05 g/L in clinical practice. Our findings further underscore that non-HCV cryoglobulin level ≤ 0.05 g/L may be responsible for severe renal and neurological complications, leading to high morbidity and mortality in these patients. Thus, our data suggest that both appropriate therapy and close follow-up may be required to improve such patients' outcome.
