Value of Fine-Needle Aspiration Cytology in Diagnosis of Hodgkin’s Lymphoma and Anaplastic Large Cell Lymphoma: One Centre Experience

The aim of the study was to determine the value and limitations of cytology in diagnosis of Hodgkin’s lymphoma (HL) and anaplastic large cell lymphoma (ALCL) as well as differentiation between these two entities. We analysed the FNA cytodiagnoses and histopathological reports, as well as treatment and survival in 89 newly diagnosed consecutive patients with these lymphomas treated in our clinical department. These patients (40 male, 49 female; age range 16–93 years; 44 in clinical stages I–II; 38 with B symptoms) were diagnosed and treated during a period of 64 months (1.1. 2004–1.5.2009). The FNA cytodiagnoses were available in 86 patients and the pathohistological diagnoses were available in 84 patients. Cytology revealed 65 classic HL, 18 ALCL and three patients in which diagnosis was not informative. Among 65 FNA cytodiagnoses of HL, comparison with histopathology was made in 61 cases and the histopathological diagnoses were as follows: 56 (91.8%) HL; three ALCL; one diffuse large B cell lymphoma and one marginal zone B cell lymphoma. In the group of 18 FNA cytodiagnoses of ALCL eight patients (53.3%) had definitive diagnosis of ALCL (either as T-cell or O type), five (33.3%) of HL and in three cases a histopathological diagnosis could not be made. These results confirm the value of FNA in diagnostic procedure in patients with HL and ALCL, especially in HL group of patients. Since we have an almost uniform group of patients according to therapeutic approach, we did univariate analyses and found out that patients with FNA cytodiagnoses of HL, younger than 55 years, with early stage of the disease and without B symptoms had significantly longer overall survival (OS). FNA cytodiagnosis has clinical relevance in differentiation between HL and ALCL

AUTOLOGOUS STEM CELL TRANSPLANTATION IN REFRACTORY OR RELAPSED DIFFUSE LARGE B CELL LYMPHOMA – A SINGLE CENTRE EXPERIENCE

Autologna transplantacija perifernih matičnih stanica zlatni je standard u liječenju refraktornog ili relapsnoga kemosenzitivnog difuznog B-velikostaničnog limfoma u pogodnih bolesnika. Cilj je ovog rada prikazati ishode autologne transplantacije perifernih matičnih stanica u bolesnika s refraktornim ili relapsnim ne-Hodgkinovim limfomom difuznoga B-velikostaničnog tipa. Retrospektivno smo analizirali podatke 62-je bolesnika liječenih autolognom transplantacijom u našem centru u razdoblju od 2000. do 2013. godine. Većina bolesnika (71%) liječena je kemoterapijom miniBEAM, a svi su primili mijeloablativnu kemoterapiju BEAM s reinfuzijom vlastitih matičnih stanica. Ukupna stopa odgovora (kom­pletna i parcijalna remisija) nakon autologne transplantacije iznosila je 75,8%. Medijan ukupnog preživljenja iznosio je 37,2 mjeseca. Medijan preživljenja bez događaja vezanih uz bolest iznosio je 16,9 mjeseci. Čimbenici statistički značajno povezani s ukupnim preživljenjem bili su aktivnost bolesti prije visokodozne spasonosne terapije, odgovor na spasonosnu terapiju. Internacionalni prognostički indeks, stadij bolesti, odgovor na autolognu transplantaciju perifernih matičnih sta­nica te radioterapija nakon autologne transplantacije. Liječenje rituksimabom nije bilo statistički značajno povezano s ishodom. U ovoj skupini bolesnika autologna je transplantacija perifernih matičnih stanica bila učinkovita u postizanju remisije i preživljenja, što je dobar i očekivan ishod navedenog postupka. Naglašavamo da je i u skupini bolesnika s kemorezistentnom bolešću autologna transplantacija bila učinkovita u 32,5% bolesnika.Autologous stem cell transplantation represents the gold standard in chemosensitive diffuse B large cell lymphoma in relapse or in refractory setting. The aim of this study was to present the outcome of peripheral autologous stem cell transplantation in patients with refractory or relapsed diffuse large B cell lymphoma. We retrospectively analysed the data of 62 patients, who underwent this procedure for the period 2000–2013. The majority of patients (71%) were treated with miniBEAM salvage chemotherapy and all received BEAM myeloablative protocol followed by the stem cell reinfusion. The overall response rate for autologous transplantation was 75.8%. Median overall survival was 37.2 months. Median event-free survival was 16.9 months. Factors associated with overall survival were state of disease prior to salvage chemotherapy, chemosensitivity of disease, International prognostic index, disease activity at the relapse, response to autologous transplantation and post-transplantation radiotherapy. The use of rituximab was not significantly correlated to the outcome. In this patient group autologous stem cell transplantation was found to be effective in achieving remission and survival showing the adequate role of this procedure in this clinical setting. We stress out that autologous stem cell transplantation was effective in 32.5% patients with chemorefractory disease after salvage therapy

Preserved C-peptide secretion in patients with type 1 diabetes and incipient chronic complications is associated with lower serum resistin and higher uric acid levels

Background and aims: Previous studies suggested that long-term perseverance of beta-cell function in patients with type 1 diabetes (T1DM) is associated with lower incidence of microvascular complications. The objective of this study was to evaluate preserved C-peptide secretion in patients with T1DM without overt chronic complications and to explore associations with resistin and uric acid as biomarkers of microvascular complication pathogenesis. ----- Materials and methods: We assessed residual beta-cell function in 164 T1DM patients (male/female = 91/73; age/diabetes duration range = 18-70/1-30 years) using an ultrasensitive C-peptide ELISA assay with detection limit of 2.5 pmol/L and total coefficient of variation (CV) 5,8% (Mercodia, Sweden). Serum level of uric acid was measured by enzymatic method (AU680, Beckman Coulter, USA) while resistin concentration was determined by the ELISA assay (Biovendor, Czech Republic). ----- Results: C-peptide secretors had shorter diabetes duration (5.1 vs. 16 years; p < 0,001), lower resistin (4.53 vs. 4.93 mg/mL p = 0.045), and higher uric acid (259 vs 238 μmol/L, p = 0.048) level than T1DM patients with no detectable C-peptide levels, while no differences in routine anthropometric and laboratory variables, including HbA1c, were observed. Although the proportion of C-peptide secretors significantly decreased across categories of diabetes duration (70%, 38%, 17% and 15% for <5, 5-10, 10-20 and 20-30 years of duration, respectively; p < 0,001), detectable C-peptide was found in 5/23 T1DM patients who were diagnosed with T1DM more than 20 years ago. ----- Conclusion: The results of our study revealed that patients with detectable C-peptide had lower resistin and higher uric acid level compared to patients with undetectable C-peptide

Serum adipocytokines are associated with microalbuminuria in patients with type 1 diabetes and incipient chronic complications

Recent studies have implicated possible contribution of adipocytokines in development and progression of microvascular complications in patients with type 1 diabetes (T1DM). The aim of our study was to investigate relationship between adipocytokines, namely leptin, resistin, adiponectin and dipeptidyl peptidase-4 (DPP-4) activity, with albuminuria in T1DM. This study included 202 T1DM without or with incipient microvascular complications. Urinary albumin excretion rate (UAE) was measured from at least two 24-h urine samples. Serum DPP-4 activity was measured by a colorimetric assay procured, and the level of adiponectin, leptin, and resistin was determined by the ELISA method. Serum DPP-4 activity and adiponectin was significantly higher in patients with normoalbuminuria compared to patients with microalbuminuria (47 vs 36 U/L, and 10.9 vs 7.3 ug/mL, respectively, p≤0.02). In multivariate logistic regression analysis adiponectin and serum DPP-4 activity was significantly associated with risk of microalbuminuria in our subjects (p≤0.04), with odds ratios of 0.72 to 0.99. However, after adjustment for age, sex, HbA1c, duration of diabetes and BMI, only serum DPP-4 activity was significantly associated with risk of microalbuminuria (p=0.008). The results of our study suggest that serum DPP-4 activity is lower in T1DM with microalbuminuria. Prospective studies are warranted to evaluate the relationship between serum DPP-4 activity and progression and development of albuminuria and nephropathy in T1DM

Association between symptoms of depression, diabetes complications and vascular risk factors in four European cohorts of individuals with type 1 diabetes - InterDiane Consortium

Aims: To investigate the association between depressive symptomatology and health markers in type 1 diabetes. Methods: Four countries from the InterDiane Consortium had adopted the Finnish Diabetic Nephropathy Study protocol, including the Beck Depression Inventory (BDI). Associations between depression symptomatology, diabetes complications (diabetic nephropathy, proliferative retinopathy, major adverse cardiovascular events [MACE]) and vascular risk factors (metabolic syndrome, body mass index, glycaemic control) were investigated. Results: In a sample of 1046 participants (Croatia n = 99; Finland n = 314; Latvia n = 315; Lithuania n = 318), 13.4% displayed symptoms of depression (BDI score 16) with no statistically significant difference in the prevalence of depression among the cohorts. The highest rates of diabetic nephropathy (37.1%) and proliferative retinopathy (36.3%) were observed in Lithuania. The rates of MACE and metabolic syndrome were highest in Finland. In joint analyses, individuals exhibiting depression symptomatology had higher HbA(1c) (79 vs. 72 mmol/mol, p <0.001) and higher triglyceride concentration (1.67 vs. 1.28 mmol/l, p <0.001), than those without. In the multivariable model, BDI score was positively associated with the presence of diabetic nephropathy, proliferative retinopathy, MACE, and metabolic syndrome and its triglyceride component. Moreover, BDI score was positively associated with the number of metabolic syndrome components, triglyceride concentration, and HbA(1c). Conclusions: Comorbid depression should be considered a relevant factor explaining metabolic problems and vascular outcomes. Causality cannot be inferred from this crosssectional study.
