Bone Marrow Findings in Multicentric Castleman Disease in HIV-negative Patients
2007
Because bone marrow histology in multicentric Castleman disease in human immunodeficiency virus-negative patients is not well reported, we investigated sequential bone marrow biopsies of 3 affected human immunodeficiency virus-negative patients, of which one was human herpes virus 8 (HHV8)-positive. The histologic evaluation of the bone marrow revealed lymphoid follicles with regressed germinal centers in 1 patient. Another patient showed tumorlike but bland polyclonal plasmacytosis with large perivascular plasma cell clusters. The HHV8-positive patient revealed interstitial HHV8-positive cells accompanied by a mild plasmacytosis. The atypical lymphoid follicles could be regarded as a bone …
Phenotypic analysis of peripheral lymphocyte subpopulations in hydatid patients.
1999
Peripheral T-lymphocytes were analyzed in three groups of people: (1) individuals with current liver hydatid disease (hydatid patients, n = 20), (2) persons who had undergone surgical cyst removal at least 2 years previously (recovered patients, n = 9), and (3) a control group of healthy volunteers (uninfected controls, n = 13). Group 1 was subdivided according to cyst status, relapse of disease, and the presence or absence of symptoms. Percentages of lymphocytes expressing CD3, CD4, CD8, CD56, CD25, CD45RA, CD45RO, and HLA-DR were determined. Symptomatic patients had proportionally fewer CD3+ CD8 + lymphocytes than the control group (P=0.038). Hydatid patients with active cysts had proport…
Autoimmune findings resembling connective tissue disease in a patient with Castleman's disease.
1997
Multicentric angiofollicular lymphnode hyperplasia (multicentric Castleman's disease) may be associated with acute phase reaction and several autoimmune features. Since lymphadenopathy is a common feature in connective tissue disease, a clear distinction between the different disease entities may be difficult. We describe a 26-year-old male patient with predominant cervical lymphadenopathy, hepatosplenomegaly and polyserositis, diagnosed as collagen disease. He showed several autoimmune features including autoimmune haemolytic anaemia, cryoglobulinaemia, positive antinuclear and anti smooth muscle antibodies, serum immune complexes and a sensorimotor polyneuropathy. Under immunosuppressive …
Soluble intercellular adhesion molecule-1 (s-ICAM-1/s-CD54) in diffuse large B-cell lymphoma: association with clinical characteristics and outcome
2003
Background: High serum levels of soluble intercellular adhesion molecule-1(s-ICAM-1/s-CD54) have been associated with adverse clinical features and poor outcome in chronic lymphocytic leukemia, Hodgkin’s disease and non-Hodgkin’s lymphoma, but their value in the different subtypes of non-Hodgkin’s lymphoma has not been well addressed. Patients and methods: Our aim was to study the serum levels of s-ICAM-1 in diffuse large B-cell lymphoma (DLBCL) and to correlate them with clinical characteristics and outcome. We analyzed the serum levels of s-ICAM-1 in a series of 55 patients with DLBCL diagnosed in a single institution. s-ICAM-1 levels were quantified by an immunoenzymatic assay. Median ag…
Risk of Non-Hodgkin Lymphoma in Celiac Disease
2002
CONTEXT: Celiac disease is one of the most common lifelong disorders. Non-Hodgkin lymphoma is a possible complication of celiac disease and may lead to a large portion of lymphoma cases. OBJECTIVE: To quantify the risk for developing non-Hodgkin lymphoma of any primary site associated with celiac disease. DESIGN AND SETTING: Multicenter, case-control study conducted between January 1996 and December 1999 throughout Italy. PATIENTS: Cases were older than 20 years (median, 57; range, 20-92 years) with non-Hodgkin lymphoma of any primary site and histological type and were recruited at the time of the diagnosis. Controls were healthy adults (2739 men and 2981 women) from the general population…
Sudden death due to cardiac sarcoidosis in a case of suspected homicide
1993
In a case of suspected homicide death due to natural causes — cardiac death (SCD) — was found at autopsy. Despite an extensive replacement of myocardial tissue by sarcoid granulomata there was no history of cardiac dysfunction or preceding symptoms. The transmurally infiltrating granulomata and the concomitant fibrosis were predominantly confluent. They occupied vast areas within the interventricular septum and the adjacent posterior wall of the left ventricle. The only other organs involved were mediastinal lymph nodes, which appeared macroscopically normal.
Ultrasound detection of abdominal lymphadenomegaly in subjects with hepatitis C virus infection and persistently normal transaminases: a predictive i…
1998
The indications for liver biopsy in anti-HCV-positive patients with persistently normal alanine aminotransferase levels are not clearly established. Recent studies have correlated the presence of abdominal lymphoadenomegaly with disease severity in patients with chronic hepatitis C. Our study aimed to evaluate the frequency of abdominal lymphoadenomegaly in an anti-HCV positive blood donor population with persistently normal alanine aminotransferase and the relationship of abdominal lymphoadenomegaly with the severity of liver changes.Eighty-six anti-HCV positive blood donors (58 M, 28 F) with normal alanine aminotransferase were followed up for a median of 31 months (range 12-50). To evalu…
Clinicopathological analysis of 1571 cutaneous malignant melanomas in Valencia, Spain: factors related to tumour thickness.
2006
Epidemiological studies on cutaneous melanoma in Mediterranean countries are scarce. Our aim was to perform a descriptive analysis of melanoma cases diagnosed in Valencia, Spain, and to evaluate the relationship between Breslow thickness and some clinical features. A total of 1571 patients with histologically confirmed cutaneous malignant melanoma diagnosed at the two main referral melanoma centres were evaluated retrospectively. For each patient the following clinical and pathological characteristics were selected: age, gender, anatomic site, histogenetic type, Breslow thickness, presence of ulceration, the stage, and symptoms such as bleeding, changes in size and colour, altered sensation…
Improved population level survival in younger Hodgkin lymphoma patients in Germany in the early 21st century.
2013
Summary Treatment for Hodgkin lymphoma (HL) is more aggressive in Germany than in the United States (US) and differences in treatment may lead to differences in population level survival. Patients diagnosed with HL in 11 German states in 1997–2006 were included in the analyses and were compared to similar analyses from patients in the Surveillance, Epidemiology, and End Results database in the US. Period analysis was used to calculate 5-year relative survival for the time period of 2002–2006 overall and by gender, age and histology. Overall 5-year relative survival for patients with HL in Germany was 84·3%, compared to 80·6% for the US. Survival was highest in patients aged 15–29 years at 9…
The Incidence of Myelofibrosis in Essential Thrombocythaemia, Polycythaemia vera and Chronic Idiopathic Myelofibrosis: A Retrospective Evaluation of …
2004
The incidence of myelofibrosis (MF) among the three major Philadelphia chromosome-negative chronic myeloproliferative disorders, i.e. essential thrombocythaemia (ET), polycythaemia vera (PV) and chronic idiopathic myelofibrosis (CIMF), is not well documented since the diagnostic criteria have recently been redefined by the WHO. Therefore we performed a retrospective analysis of follow-up biopsies of 275 patients with ET, PV and CIMF according to the WHO classification of chronic myeloproliferative disorders. In the diagnostic bone marrow biopsies, MF was observed in 57 of the 136 CIMF patients (42%), 4 of the 73 PV patients (5%) and none of the 66 patients with ET. Within a median observati…
