ABSTRACT
OBJECTIVE: To investigate the clinical efficacy and prognosis of Rituximab combined with DHAX and CHOP regimen in the first-line treatment of elderly patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). METHODS: A total of 36 elderly patients with DLBCL who were admitted and treated with 3 of more courses of treatment from August 2011 to August 2021 were retrospectively analyzed, and they were divided into rituximab±DHAX (R±DHAX) regimen group (18 cases) and rituximab±CHOP (R-CHOP) regimen group (18 cases) according to the treatment plan, and clinical features, efficacy and survival of the patients were observed. RESULTS: Compared with R-CHOP group, patients of the R±DHAX group were older, and had worse performance status and higher IPI score, the differences between two groups in age, ECOG score and IPI score were statistically significant ( P =0.005 P =0.018, P =0.035), but there were no significant differences beween two groups in gender, whether there were B symptoms, whether LDH was elevated, whether there was extranodal involvement, cell origin, bone marrow infiltration, and whether rituximab was combined ( P =0.738, P =1, P =0.315, P =0.305, P =0.413, P =0.177, P =0.711, P =0.229). The efficacy could be evaluated in 36 cases, including CR 14 (38.9%), PR 17 (47.2%), PD 5 (13.9%), and ORR of 86.1% (31/36). There were no statistically significant differences in CRï¼»(27.8%ï¼5/18ï¼ vs 50.0%ï¼9/18ï¼; P >0.05ï¼½ and PR ï¼»44.4%ï¼8/18ï¼ vs 50.0%ï¼9/18ï¼; P >0.05ï¼½ of R±DHAX group and R-CHOP group, there was statistically significant difference in ORRï¼»72.2%ï¼13/18ï¼ vs 100.0%ï¼18/18ï¼; P =0.045ï¼½ between two groups. The 1-year OS of R±DHAX group and R-CHOP group was (38.9±11.5%)% and (94.4±7.4%)%, respectively, 2-year OS was (16.7±8.8)% and (72.2±10.6)%, respectively, and the differences between two groups were statistically significant ( P =0.001, P =0.002). The median survival time in the R±DHAX group was 11 months(95%CI :8.9-13.1), and the median survival time in the R-CHOP group was not reached, and there was a statistically significant difference between the groups (P < 0.001). CONCLUSION: For elderly DLBCL patients, R±DHAX may not be superior to R-CHOP in OS, and ECOG score, IPI score and age may affect the survival of elderly DLBCL patients. However, R±DHAX regimen is safe, tolerable and has a certain efficacy, which can be used as one of the clinical treatment options for elderly DLBCL.

RATIONALE: Neuroblastoma amplified sequence (NBAS)-associated disease is an autosomal recessive disorder and a broad spectrum of clinical symptoms has been reported. However, autoimmune mediated hemolytic anemia (AIHA) is rarely reported in NBAS disease. PATIENT CONCERNS: A now 21-year-old male harbors heterozygous variants of c.6840G>A and c.335 + 1G>A and was found had retarded growth, hypogammaglobulinemia, B lymphopenia, optic atrophy, horizontal nystagmus, slight splenomegaly and hepatomegaly since childhood. This case had normal hemoglobin level and platelet count in his childhood. He developed AIHA first in his adulthood and then thrombocytopenia during the treatment of AIHA. The mechanism underlying a case with pronounced hypogammaglobulinemia and B lymphopenia is elusive. In addition to biallelic NBAS mutations, a germline mutation in the ANKRD26 (c.2356C>T) gene was also detected. So either autoimmune or ANKRD26 mutation-mediated thrombocytopenia is possible in this case. INTERVENTION AND OUTCOME: He was initially managed with steroid and intermittent intravenous immunoglobulin supplement. After treatment, he responded well with a normalization of hemoglobin and serum bilirubin. But the patient subsequently experienced severe thrombocytopenia in addition to AIHA. He was then given daily avatrombopag in addition to steroid escalation. He responded again to new treatment, with the hemoglobin levels and platelet counts went back to the normal ranges. Now he was on de-escalated weekly avatrombopag and low-dose steroids maintenance. CONCLUSION: The phenotype of this case indicates that c.335 + 1G>A NBAS variant is probably a pathogenic one and c.2356C>T ANKRD26 variant is improbably a pathogenic one. AIHA may respond well to steroid even when happened in patients with NBAS disease.

OBJECTIVE: To study the incidence and risk factors of herpes zoster in patients with multiple myeloma and to evaluate the preventive effect of antiviral therapy. METHODS: The clinical features of multiple myeloma patients with herpes zoster were retrospectively analyzed, the risk factors of herpes zoster and the effect of antiviral prophylaxis were analyzed. RESULTS: Among 180 patients with multiple myeloma, 23 cases developed herpes zoster (12.8%). The incidence of herpes zoster was 19.1% in patients with renal dysfunction and 23.5% after autologous hematopoietic stem cell transplantation (ASCT). The incidence of herpes zoster was higher in patients receiving bortezomib-containing regimens (21/137, 15.3%) than that in those without bortezomib (2/43, 4.7%), but there was no statistical difference (P =0.067). Antiviral prophylaxis was associated with fewer zoster infections, 8/111(7.2%) developed herpes zoster in patients who received antiviral prophylaxis, and 15/69 (21.7%) in those receiving no prophylaxis(P =0.005). 65.2% of patients with herpes zoster did not receive antiviral prophylaxis. Multivariate analysis showed that bortezomib treatment, AHSCT and renal dysfunction were independent risk factors for multiple myeloma with herpes zoster, while antiviral prophylaxis was independently associated with reducing the risk of herpes zoster. Herpes zoster had no effect on OS in patients with multiple myeloma. CONCLUSION: The risk of herpes zoster in multiple myeloma patients was increased. Antiviral prophylaxis can reduce the risk of herpes zoster in patients on bortezomib-based therapy.
