OBJECTIVETo investigate the relationship between the etiology, laboratory findings and prognosis of secondary HPS, so as to enhance the understanding of the secondary HPS and the related factors affecting prognosis, reduce the misdiagnosis and to understand the factors that affect the prognosis.

METHODSThe etiology, laboratory findings and prognosis of 61 patients with secondary HPS were analyzed retrospectively.

RESULTSUnivariate analysis showed that TG, FIB, SF, ANC, ALB, TBIL, ALT, LDH were significantly different between the 2 groups of the patients with secondary HPS. Multiariate factor analysis showed that the LDH and the etiology affected the prognosis of the patients with secondary HPS. The prognosis of the patients with elevated LDH, viral infection, especially EB virus infection, tumor and unknown causes might be poor.

CONCLUSIONSThe etiology and clinical characteristics of prognosis are diverse. The cause needs to be identified as soon as possible. The prognosis should be judged according to LDH and other indicators. Then, targeted therapy should be used to control the disease in the short time.

OBJECTIVE: Review and analyze the characteristics of bone marrow cell morphology in patients with Epstein-Barr virus (EBV) infection, and explore the diagnostic value of bone marrow cell morphology for the early identification of EBV infection. METHODS: A total of 33 patients with EBV-DNA positive detection in the First Affiliated Hospital of Guangxi Medical University from January 2018 to May 2021 were collected as the research objects. Bone marrow cell morphology and peripheral blood cell analysis were performed, and the significance in disease diagnosis was analyzed by statistical methods. RESULTS: The sampling satisfaction of 33 patients with EBV infection was 100%. In the clinical diagnosis of all cases, 7 cases were IM, 17 cases were EBV-HLH, 3 cases were lymphoma, 2 cases were EBV-associated lymphoid hyperplasia, and 4 cases were not diagnosed. Among them, 31 patients had active bone marrow hyperplasia or above, 26 patients had active granulocytic hyperplasia or above, 21 patients had active erythroid hyperplasia or above, and 17 cases of megakaryocyte production platelet function decreased. The abnormal components of bone marrow mainly indude atypical lymphocyte cells (33 cases), hemophagocytic cells (22 cases), abnormal histiocyte (10 cases). CONCLUSION According to the proliferation of granulocytes, erythrocytes and megakaryocytes in the bone marrow, and the emergence of abnormal components such as atypical lymphocytes, hemophagocyte, abnormal histiocyte. Bone marrow cell morphological examination can indicate the possibility of EBV infection, which is certain diagnostic value for early identification of EBV infection.

Objective: To investigate the clinicopathological features and prognosis of cytotoxic T-cell lymphoma (CTL). Methods: The clinicopathological data of 134 CTL patients in Beijing Friendship Hospital Affiliated to Capital Medical University, the 989 Hospital of PLA Joint Logistics Support force (formerly the 152 Hospital) and the Fourth Hospital of Hebei Medical University from 2008 to 2020 were retrospectively collected. Immunophenotype, Epstein-Barr virus infection status and T cell receptor (TCR) clonality of tumor cells were assessed, and clinicopathological features and prognosis of patients were analyzed. Results: Among the 134 CTL patients, the male to female ratio was 1.7∶1.0, the median age was 49.5 years (range 3-83 years), and 100 cases (74.6%) were under 60 years old. Forty-six point nine percent of the patients (53/113) had B symptoms. Most of the patients presented with systemic superficial lymphadenopathy. According to the Ann Arbor staging system, 36.8% (39/106) of the patients were in stage Ⅰ-Ⅱ, and 63.2% (67/106) in stage Ⅲ-Ⅳ. The rate of extranodal involvement was 51.6% (66/128). Spleen was involved in 24.2% (31/128) of the cases. Morphology showed diffuse growth of abnormal lymphocytes, infiltrating and destroying normal tissue structure. Immunohistochemical staining showed that tumor cells expressed T cell antigens (CD2, CD3, CD5, and CD7), and 72.0% (77/107) of them had decreased or lost expression of one or more antigens. According to the numbers of CD4 and CD8 expression in tumor cells, 70 cases (52.2%) were grouped into CD8⁺>CD4⁺group. The expression rates of TIA-1 and granzyme B were 99.2% (119/120) and 79.8% (95/119), respectively. CD20 abnormal expression rate was 27.6% (37/134) and CD56 was negative in all cases. The median Ki-67 proliferative index was 45.0% (range 5%-80%). In situ hybridization of small RNA encoded by Epstein-Barr virus was negative. Clonal TCR gene rearrangement analysis was performed on 49 cases and was positive in all cases. Ninety-one patients were followed up for a median of 36 months (range, 1 to 240 months), and 40 of the 91 patients (44.0%) died. The twenty-three patients were in complete remission (including 13 cases with localized single extranodal mass). The 3-year and 5-year overall survival rates were 53.5% and 49.4%, respectively. Univariate analysis showed that B symptom, spleen involvement, extranodal involvement, clinical stage, CD8⁺>CD4⁺phenotype, abnormal expression of CD20 and Ki-67 proliferation index (>60%) were associated with overall survival (P<0.05). The multivariate Cox regression analyses showed that spleen involvement and CD8⁺>CD4⁺ phenotype were independent prognostic factors for overall survival in CTL patients. Conclusions: CTL are more commonly found in adult males under 60 years old, often accompanied by B symptom, with a high proportion of extranodal involvement and more CD8 positive phenotypes. Spleen involvement and CD8⁺>CD4⁺phenotype are independent predictors of CTL overall survival. Some patients with localized extranodal CTL may have a good prognosis.
