Abstract
Fas and Fas ligand (FasL)-induced cell death is critical for the appropriate regulation of immune responses, especially those mediated by T cells. In this letter, several studies are discussed that reinforce the importance of FasL intracellular signaling for CD4 + T cell death, which might involve PSTPIP phosphatase and/or MAPKs.

Abstract
BACKGROUND Autoantibodies against C1-inhibitor (C1-INH-Ab) have a diagnostic value in acquired angioedema due to C1-inhibitor deficiency (C1-INH-AAE), even though antibodies can circulate in complexes, which can be undetectable by proven methods. Our aim was to measure C1-INH/C1-INH-Ab complexes (CAC) and investigate their connection to C1-INH-Ab and the changes in their titer over time. RESULTS 19 patients were diagnosed with C1-INH-AAE in the Hungarian Angioedema Center of Reference and Excellence; 79% of them had an underlying disease. Samples were examined with a newly developed in-house complex ELISA method. Patients with high C1-INH-Ab titer had a CAC titer which did not exceed the normal level and the ones with high CAC titer had a C1-INH-Ab titer which did not exceed the normal level. In case of those patients who had C1-INH-Ab and CAC of the same type of immunoglobulin, the increasing titer of C1-INH-Ab went together with the decreasing level of CAC and vice versa. CAC titer was already increased before the diagnosis of the underlying disease. CONCLUSIONS Free circulating and complex antibodies are in a dynamically changing equilibrium. CAC measurements can help to predict the development of an underlying disease. The efficiency of the treatment for underlying disease can be monitored by the decreasing CAC titers. Our results show that the CAC can be of important additional information besides the complement panel examination in case of C1-INH-AAE. Measurement of CAC is recommended to be done parallelly with C1-INH-Ab, so as to detect both free and bound antibodies.

Abstract
BACKGROUND Celiac disease has been associated with increased mortality, but data on long-term mortality are scarce. AIMS To determine long-term mortality in celiac disease. METHODS The study cohort consisted of all celiac disease patients (n=1,392) diagnosed in Tampere University Hospital catchment area 1960 - 2000. Patients were categorized into subgroups based on demographic (age, gender, decade of diagnosis) and celiac disease characteristics (e.g., phenotype, severity of villous atrophy) collected from medical records. Overall and cause-specific mortality was compared to those of age-, sex-, and place of residence matched reference individuals (n=4,177) over time. RESULTS During the 41 years of follow-up (median 26.5 years), 376 celiac disease patients and 1,155 reference individuals died. All-cause mortality was not increased (hazard ratio (HR) 0.96, 95% confidence intervals (CI) 0.85-1.08). Mortality from lymphoproliferative diseases and diseases of the central nervous system was increased (HR 2.42, 95% CI 1.38-4.24 and HR 2.14, 95% CI 1.05-4.36 respectively) while the risk from alcohol related diseases was decreased (HR 0.31, 95% CI 0.09-1.00). Examination of various celiac disease phenotypes revealed no significant differences in mortality CONCLUSIONS: Overall mortality was not increased in any celiac disease phenotype during a very long-term follow-up.

Abstract
BACKGROUND Acquired deficiency of C1 inhibitor (AAE-C1-INH) is a very rare cause of recurrent angioedema, with few cases reported in the literature. We aimed to describe a series of patients with AAE-C1-INH who were diagnosed and received care at angioedema reference centers in Brazil, affiliated to the Brazilian Group of Studies on Hereditary Angioedema. METHODS Fourteen patients from 8 Brazilian Angioedema Reference Centers, diagnosed with AAE-C1-INH, were included in this study. Clinical data collected included sex, date of birth, date of onset of symptoms, date of diagnosis, plasma levels of antigenic and/or functional C1-INH, levels of C4 and C1q, location and treatment of angioedema attacks, long-term prophylaxis, associated diseases, and definitive treatment. RESULTS Fourteen patients were identified with AAE-C1-INH. Most patients (10/14; 71.4%) were female. The median age at onset of symptoms was 56.5 years (range, 14-74 years; interquartile range [IQR], 32-64 years), and median age at diagnosis was 58.0 years (range, 20-76 years; IQR, 38-65 years), with a median time until diagnosis of 2 years (range, 0-6 years; IQR, 1-3 years). The most common manifestations were cutaneous (face, eyelids, lips, trunk, hands, feet, and genitals). Most patient had low levels of C4 (13/14; 92.8%) and of antigenic C1-INH (8/14; 57.1%). Four had decreased functional activity of C1-INH (4/7; 57.1%) and C1q levels were low in 5 patients (5/12; 41.6%). Underlying diseases were identified in all 14 patients, with lymphoma of the splenic marginal zone and monoclonal gammopathy of undetermined significance being the most frequent. Nine patients (64.2%) needed long-term prophylactic treatment for recurrent angioedema and 5 patients (46.7%) required treatment for angioedema attacks. Most of them (12/14; 85.7%) had resolution of angioedema. CONCLUSION Therapy of AAE-C1-INH aims to control symptoms; however, diagnosis and treatment of the underlying disease, when present, should be an important target and may lead to the resolution of angioedema in patients with AAE-C1-INH.

Abstract
Neurofibromatosis 1 (NF1) is an inherited, autosomal-dominant, tumor predisposition syndrome with a birth incidence as high as 1:2000. A patient with NF1 is four to five times more likely to develop a malignancy as compared to the general population. The number of epidemiologic studies on lymphoproliferative malignancies in patients with NF1 is limited. The aim of this study was to determine the incidence rate of lymphoproliferative malignancies (lymphoma and leukemia) in NF1 patients followed in our referral center for neurofibromatoses. We used the Informatics for Integrated Biology and the Bedside (i2b2) platform to extract information from the hospital’s electronic health records. We performed a keyword search on clinical notes generated between Jan/01/2014 and May/11/2020 for patients aged 18 years or older. A total of 1507 patients with confirmed NF1 patients aged 18 years and above were identified (mean age 39.2 years; 57% women). The total number of person-years in follow-up was 57,736 (men, 24,327 years; women, 33,409 years). Mean length of follow-up was 38.3 years (median, 36 years). A total of 13 patients had a medical history of either lymphoma or leukemia, yielding an overall incidence rate of 22.5 per 100,000 (0.000225, 95% confidence interval (CI) 0.000223–0.000227). This incidence is similar to that of the general population in France (standardized incidence ratio 1.07, 95% CI 0.60–1.79). Four patients had a medical history leukemia and 9 patients had a medical history of lymphoma of which 7 had non-Hodgkin lymphoma, and 2 had Hodgkin lymphoma. Our results show that adults with NF1 do not have an increased tendency to develop lymphoproliferative malignancies, in contrast to the general increased risk of malignancy. While our results are consistent with the recent population-based study in Finland, they are in contrast with the larger population-based study in England whereby NF1 individuals were found to be 3 times more likely to develop both non-Hodgkin lymphoma and lymphocytic leukemia. Large-scale epidemiological studies based on nationwide data sets are thus needed to confirm our findings.

Abstract
Richter's transformation from chronic lymphocytic leukemia (CLL) to aggressive lymphoma is a relatively rare event with well-characterised clinical and radiological features, and can typically be distinguished from infectious complications of CLL. Opportunistic infections in CLL happen predominantly in the context of immunosuppressive therapy and/or relapsed/refractory disease. Herpes simplex viral (HSV) lymphadenitis is a rare phenomenon in treatment-naive CLL patients with only six cases reported in the English-language literature. Its diagnosis is challenging; its management and the outcome of the subsequent treatment for CLL are not well documented. We report three cases of rapidly progressive lymphadenopathy occurring in the context of previously untreated CLL, clinically and radiologically mimicking Richter's transformation, but histologically confirmed as necrotic HSV lymphadenitis. We describe the presentation, diagnosis and management of all three cases, including for the first time the positron emission tomography-computed tomography (PET-CT) appearance of this condition, as well as how we later on delivered CLL-directed immunochemotherapy safely and successfully without recrudescence of HSV-related disease. Our cases underscore the importance of obtaining biopsy in all cases of rapidly progressive or disconcordant lymphadenopathy in CLL patients, or in those with highly 18FDG-avid adenopathy on PET-CT.

Abstract
INTRODUCTION Due to the beginning of the use of immunophenotypic and cytogenetic techniques, new nosological forms of lymphoproliferative diseases have appeared over the past few decades. According to the WHO classification (2008), today there are more than 50 known lymphoproliferative diseases. CASE PRESENTATION We present the case of a 51-year-old man with lymphoproliferative syndrome. Our patient underwent morphological and immunohistochemical investigations of biopsy materials from the right inguinal lymph node. The morphological picture was characteristic for small cell lymphoma. Immunophenotypically, tumor proliferate cells expressed CD20, CD76b, CD5, and cyclin D, and the tumor immunophenotype matched mantle cell lymphoma. DISCUSSION At the present stage of the development of medicine, the diagnosis of lymphoproliferative diseases is based on the clinical picture of the disease with the definition of localization and characteristics of the tumor process, morphological study of tumor tissue and cells, and immunophenotypic and/or cytogenetic analyses are mandatory to determine the final diagnosis.

Abstract
Epstein-Barr virus (EBV) is one of the most common viruses, infecting more than 90% of the adult population worldwide. EBV genome is detected in some lymphoid neoplasms. Not only their histopathological subtypes, but also their backgrounds and their clinical courses are variable. A number of B-cell lymphoproliferative disorders associated with the immunocompromised state are related to EBV infection. The incidences of these disorders have been increasing along with generalization of organ transplantations and use of immunosuppressive treatments. Furthermore, some EBV-positive lymphoma can also occur in immunocompetent patients. While evaluating patients with generalized lymphadenopathy of unknown cause by positron emission tomography/computed tomography with 2-deoxy-2-[18F]fluoro-D-glucose (FDG-PET/CT), the possibility of lymphoid neoplasms should be considered in some patients, and a careful review of the background and previous history of the patients is necessary. In this review article, we describe the pathogenesis of EBV-related lymphoid neoplasms and then present FDG-PET/CT images of representative diseases. In addition, we also present a review of other EBV-related diseases, such as infectious mononucleosis and nasopharyngeal carcinoma.

Abstract
AIM To assess the potential value of femoral head (FH) volume measurements to predict joint collapse, as compared to articular surface involvement, in post-treatment osteonecrosis (ON) in pediatric patients affected by lymphoproliferative diseases.
METHODS Considering 114 young patients with lymphoproliferative diseases undergone a lower-limbs magnetic resonance imaging (MRI) examination between November 2006 and August 2012 for a suspected post-treatment ON, we finally considered a total of 13 cases (7 males, mean age 15.2 ± 4.8 years), which developed a FH ON lesions (n = 23). The MRI protocol included coronal short tau inversion recovery and T1-weighted sequences, from the hips to the ankles. During the follow-up (elapsed time: 9.2 ± 2 mo), 13/23 FH articular surface (FHS) developed articular deformity. The first MRI studies with diagnosis of ON were retrospectively analyzed, measuring FH volume (FHV), FHS, ON volume (ONV) and the articular surface involved by ON (ONS). The relative involvement of FHS, in terms of volume [relative volume (RV): ONV/FHV] and articular surface [relative surface (RS): ONS/FHS], was then calculated.
RESULTS By using receiver operating characteristic curve analysis (threshold of 23% of volume involvement), RV predicted articular deformity in 13/13 FHS [sensitivity 100%, specificity 90%, accuracy 95%, positive predictive value (PPV) 93%, negative predictive value (NPV) 100%]. Considering a threshold of 50% of articular involvement, RS predicted articular deformity in 10/13 femoral heads (sensitivity 77%, specificity 100%, accuracy 87%, PPV 100%, NPV 77%).
CONCLUSION RV might be a more reliable parameter than RS in predicting FH deformity and could represent a potential complementary diagnostic tool in the follow-up of femoral heads ON lesions.

Abstract
Mixed cryoglobulinemia is often associated with hepatic C virus infection and is less common with hepatitis B virus infection, and it often progresses into lymphoproliferative diseases. Rituximab is known to achieve systemic B-cell depletion and clinical remission of the systemic effects of cryoglobulins in hepatitis C virus-associated cryoglobulinemia. Conversely, there are few reports regarding the use of rituximab in hepatitis B virus-associated cryoglobulinemia. We report here the case of a 65-year-old Japanese female who presented with lymphoproliferative disease-related cryoglobulinemia with hepatitis B virus, including membranoproliferative glomerulonephritis with renal failure. The vasculitis was refractory to conventional and antiviral therapy, but rituximab use led to control the disease. Our case highlights the benefit and efficacy of rituximab in association with antiviral therapy in small vessel vasculitis related to lymphoproliferative disease-related cryoglobulinemia with hepatitis B virus.

Abstract
Molecular methods are important tools for diagnosis and monitoring of many lymphoproliferative disorders. The reliability of lymphoma diagnoses is strikingly different between developed and developing countries, partly due to lack of access to these advanced molecular analyses. To overcome these problems, we propose a new application of dried blood spots (DBS) for detecting clonal B-cell populations in peripheral blood (PB). We ensured that the DBS contained sufficient lymphocytes to perform a PCR-based clonality assay without producing false positives. Using the Namalwa B-cell line, we established that the assay is sensitive enough to detect 200 clonal cells in the analyzed sample. Very similar clonal results were obtained between DNA from DBS and fresh whole blood from patients with B-cell chronic lymphocytic leukemia. B-cell clonality can also be detected in DBS from African children with EBV-associated diseases. This is the first study demonstrating that clonality testing can be performed on DBS samples, thus improving the diagnostic and monitoring options for lymphoproliferative diseases in resource-limited settings.

Abstract
BACKGROUND The clinical course of patients with B-cell CLL is often complicated by autoimmune phenomena. The DAT might be positive at some time during the course of the disease in up to 35% of cases. The aim of this retrospective study was to investigate the relationship between the occurrence of a positive DAT and biological features of CLL patients. PATIENTS AND METHODS In our institution, 146 untreated patients with CLL were studied using the DAT. RESULTS According to the statistical analysis, a high level of β2-microglobulin and unmutated IgHV emerged as factors significantly related to the presence of DAT positivity. Time to first TFS was significantly shorter in DAT-positive patients. The adverse effect of a DAT positive result was maintained in terms of TFS when patients with mutated IgHV status were excluded from statistical analysis. CONCLUSION These results suggest that the DAT might provide additional prognostic information regarding patients with IgHV unmutated status.

Abstract
Involvement of the serosa may be the presenting feature in a wide and complex variety of lymphoproliferative diseases, with differing clinical outcomes covering a spectrum of benign and malignant conditions. Effusions involving peritoneal and pericardial cavities are uncommon during the course of hematological malignancies. Obstructive and/or infiltrative tumor mass or vascular leakage due to stimulation by vascular endothelial growth factor contribute to the pathogenesis. In addition to clinical findings, cytomorphology and flow cytometric immunophenotyping of the serosal fluid yield valuable information in the differential diagnosis of lymphocytic infiltrates. Herein, we describe the case of primary mantle cell lymphoma in a 75-year-old man presenting with abdominal fullness and weight loss, suggesting a gastrointestinal pathology.
