Lymphoproliferative disorders and autoimmune diseases have some common aspects in their clinical appearance. We reviewed 940 patient charts with malignant lymphomas to assess the rate of associated autoimmune diseases. Of 421 non-Hodgkin's lymphoma (NHL) patients (230 males, 191 females), 32 (7.6%) had an autoimmune disease (26 females, six males, mean age 48.3 years). The most common diagnosis was Sjögren's syndrome. The other cases were autoimmune skin diseases (5), thyroiditis (3), polymyositis (2), scleroderma (2), other musculoskeletal disorders (2), rheumatoid arthritis (1), vasculitis (1), undifferentiated collagenosis (1), colitis ulcerosa (1), autoimmune hepatitis (1), Addison's disease (1), and autoimmune hemolytic anemia (1). Of 519 Hodgkin's lymphoma patients (308 males, 211 females), an associated autoimmune disease occurred in 45 (8.6%) (25 females, 20 males, mean age 39.2 years). In 31 cases, we found autoimmune thyroid disorders, then came glomerulonephritis (3), immune thrombocytopenia (3), insulin-dependent diabetes mellitus (2), autoimmune hemolytic anemia (1), seronegative spondylarthritis (1), systemic lupus erythematosus (1), mixed connective tissue disease (1), scleroderma (1), and vasculitis (1). We also analyzed histology, choice of treatment, and sequence of appearance of the disease types. We found a difference between NHL and Hodgkin's lymphoma patients, since in NHL autoimmunity - mostly from Sjögren's syndrome - preceded the lymphoma diagnosis (70%), but in Hodgkin's the autoimmunity developed mainly after the treatment of malignancy. The relatively high prevalence of autoimmune diseases in malignant lymphomas has several explanations. Clinicians have to consider autoimmunity when treating lymphoproliferative disorders.
During the follow-up of thyroid function of 151 patients with Hodgkin’s disease in complete remission for at least 1 year, 26 cases of subclinical, 12 cases of manifest clinical hypothyroidism and 2 cases of hyperthyroidism (Graves-Basedow disease) were confirmed. Thyroid dysfunction was more frequent in patients who had undergone mantle or neck radiotherapy. Hypothyroidism was most often revealed from the 6th year on following radiotherapy. Thyroid autoantibody positivity was found to be more frequent in patients with thyroid dysfunction, and conversely, thyroid dysfunction was more frequent among the 28 patients with autoantibody positivity. Ultrasound examination and fine needle aspiration cytology of the thyroid confirmed thyroiditis in 96% of the patients with antibody positivity. No relationship was found between thyroiditis and the form of treatment for Hodgkin’s disease. We have found that both neck irradiation and thyroiditis may play a role in the increased number of thyroid dysfunction in patients treated for Hodgkin’s disease. Thyroiditis is not caused by neck radiotherapy but may be the result of immune regulation disorders in Hodgkin’s disease. For substitution or isohormone therapy, levothyroxine is suggested for use. We suggest that examination of the thyroid should be performed at least once a year during the follow-up of Hodgkin’s disease patients.
Daratumumab is a human anti-CD38 monoclonal antibody used in the treatment of refractory and relapsed multiple myeloma. We investigated the efficacy and safety of daratumumab therapy in a real-world setting. Ninety-nine Hungarian patients were included; 48 received monotherapy, while lenalidomide and bortezomib combinations were administered in 29 and 19 cases, respectively. Overall response rate was assessable in 88 patients, with 12 complete, 10 very good partial, 34 partial, and seven minor responses. At a median duration of follow-up of 18.6 months, median progression-free survival (PFS) among all patients was 17.0 months. These values were inferior in the bortezomib combination and monotherapy groups. Patients with early-stage disease (ISS1) had better survival results than those with stage 2 or 3 myeloma (p = 0.009). Heavily pretreated patients had inferior PFS compared to those with 1-3 therapies (p = 0.035). Patients with impaired renal function had PFS results comparable with those having no kidney involvement. There were 10 fatal infections, and the most frequent adverse events were mild infusion-associated reactions and hematologic toxicities. Our results confirm that daratumumab is an effective treatment option for relapsed/refractory MM with an acceptable safety profile in patients with normal and impaired renal function.
Ixazomib-Revlimid-Dexamethasone is an all-oral treatment protocol for multiple myeloma with a manageable tolerability profile which was available through a named patient program for Hungarian patients from December 2015 to April 2017. We analyzed the clinical characteristics and survival of 77 patients treated at 7 centers within this program. The majority of patients responded, we found complete response in 9, very good partial response in 8, partial response in 32, minor response or stable disease in 13 and progressive disease in 11 patients. Progression free survival was 11.4 months. There was a trend of longer progression free survival in those with 1 vs. >1 prior treatment, with equally good effectivity in standard risk and high risk cytogenetic groups. The adverse events were usually mild, none leading to permanent drug interruptions. There were 5 fatalities: 3 infections and 2 pulmonary embolisms. Our real word data support the use of Ixazomib-Revlimid-Dexamethasone as a highly effective and well tolerated oral treatment protocol for relapsed myeloma.
The addition of rituximab to conventional chemotherapy has significantly improved the treatment outcome in diffuse large B-cell lymphoma. However, differences in treatment response and survival data can be observed independently from the International Prognostic Index scores. The current study evaluated the impact of Fc-gamma-receptor IIIa polymorphism and gene expression profile on the response of DLBCL patients to R-CHOP therapy as well as on their survival results. Fifty-one patients were involved, thirty-two females, nineteen males, their median age was 53.1 years. The FCGR3A polymorphism at the 158. amino acid position determined with PCR method showed the following results: VV: 12 cases (23.5%), VF: 29 cases (56.8%) and FF: 10 cases (19.6%), respectively. There was no significant difference between the treatment responses of the three groups. The event-free survival data were less favorable in the F-allele carriers than in V/V homozygous patients, but without any significancy, and the overall survival curves were almost the same. As for the gene expression profile, 20 patients' biopsy specimens showed germinal center and 31 showed non-germinal center characteristics. Treatment results did not differ from each other in the two groups. Both the event-free and the overall survival data were more favorable in the GC group, however the differences were not significant. Our results contest the predictive value of Fc-gamma-receptor IIIa polymorphism and gene expression profile in diffuse large B-cell lymphoma.
