Analysis of clinical characteristics and prognosis factors of 71 cases with HIV-negative Castleman’s disease: hypoproteinemia is an unfavorable prognostic factor which should be treated appropriately

Abstract

Purpose

HIV negative Castleman's disease has been reported as a group of poorly understood lymphoproliferative disorder, and we want to explore the clinical feature and prognosis factors of CD.

Methods

We retrospectively collected the clinical information of 71 CD patients without HIV infection diagnosed in the first affiliated hospital of Zhengzhou university.

Results

Different clinical classifications, including 35 patients (49.30%) with unicentric Castleman disease and 36 (50.7%) with multicentric Castleman disease, has their specific features compared with each other and unfavorable risk factors calculated by the univariate analysis. As for all of CD patients without HIV infection, there were 7 significant risk factors identified by the results of log-rank test, including clinical complaint, edema (hydrothorax, ascites, pelvic effusion), fatigue, anemia, hypoproteinemia and elevated serum β2-MG. Then, we created a Cox regression model of these clinical and statistic significant factors which indicated hypoproteinemia was an independent poor prognosis factors of CD in both univariate and multivariate analysis.

Conclusions

Our study emphasized the distinction of clinical characteristics between UCD and MCD and the importance of different poor risk factors of different clinical classifications which may directed more precise and appropriate treatment strategy.
