• To explore the clinical characteristics and outcomes in Chinese patients with type I cryoglobulinemia (CG), we retrospectively analyzed the clinical data, management, and outcomes of 45 patients diagnosed with type I CG in our hospital from January 2015 to March 2019. In our study, all type I CGs were secondary to hematologic diseases, and monoclonal gammopathy of unknown significance was the most common primary disease, accounting for 48.9% ( n = 22). Additionally, B cell non-Hodgkin lymphoma, Waldenström’s macroglobulinemia, and multiple myeloma accounted for 24.4% ( n = 11), 20.0% ( n = 9), and 6.7% ( n = 3), respectively. In patients with type I CG, skin damage was the most common symptom, presenting in 57.8% of the patients, followed by peripheral neuropathy (22.2%) and renal involvement (15.6%). Treatment was initiated in 29 patients (64.4%), and the most common choice was a rituximab-based regimen in 13 patients (44.8%), followed by bortezomib-based regimen in 11 patients (37.9%). Clinical symptoms were significantly improved after treatment, and the clinical remission rate was 86.2%, including 34.5% of complete clinical remission, while the laboratory response rate was 88.9%, including 33.3% of complete response and 55.6% of partial response. The expected 1-year overall survival was 97.8%. In conclusion, for patients with multisystemic involvement, such as skin damage, kidney damage, or peripheral neuropathy, the diagnosis of type I CG should be considered, and the underlying disease needs to be explored. Symptoms and primary diseases should be taken into consideration before choosing initial management.
