Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in elderly people. The clinico-hematological profile and treatment outcome of patients with CLL were assessed using retrospective case record analysis over 11 years. There were 95 (75 males: 20 females) patients with a median age of 61 years. Thirty patients were aged 55 years or less (young CLL patients) and 65 were more than 55 years of age (elder CLL patients). Sixty percent patients had non-specific complaints, such as weakness, cough and indigestion. Twenty-six (27%) patients had pallor and 24 (25%) had fever as initial presenting manifestation. Bleeding manifestations were seen in 7 patients. Seven patients were diagnosed incidentally. Lymphadenopathy, splenomegaly and hepatomegaly were seen in 52 (55%), 63 (66%) and 60 (63%) patients, respectively. The median white blood cell count and absolute lymphocyte counts were 70,600 and 51,490/mul, respectively. Three patients had autoimmune hemolytic anemia. Twenty-five patients (26%) had anemia with hemoglobin < 11 g/dl and thrombocytopenia with platelet count 100 x 10(3)/mm(3) was seen in 17 (18%). Interstitial nodular, mixed and diffuse bone marrow (BM) involvement was seen in 10.2, 67.3, 6.1 and 16.3% cases, respectively. Eighteen (60%) young patients and 35 (54%) older patients required treatment with chlorambucil. The mean time from initial diagnosis to treatment was 4.6 +/- 10.7 months. None of our patient attained complete response. Six patients obtained partial response. Median duration of chlorambucil was 7 months (1-86 months). Forty-six patients had stable disease. Three patients died. Median survival of study group was 4 years (8 months-13 years). In older CLL it was 4 years (8 months-11 years) and in young patients, survival duration was 5.5 years (1-13 years).

Angioimmunoblastic T-cell lymphoma most often affects the elderly. Patients present with generalized lymphadenopathy and systemic symptoms; half also have hepatomegaly, splenomegaly and a rash. Polyclonal hypergammaglobulinemia, elevated lactate dehydrogenase, and anemia are the main laboratory abnormalities. Autoimmune phenomena (including autoimmune hemolytic anemia, immunologic thrombocytopenia, and autoantibodies) are common. Lymph node biopsy is needed to confirm this diagnosis. Genetic analysis that reveals a monoclonal T-cell population is also relevant. The underlying immune deficiency explains the frequency of infections. Most patients are treated with combination chemotherapy. Autologous stem cell transplantation is proposed to the youngest. Immunosuppressive drugs may be appropriate for elderly or relapsing patients. The overall 5-year survival rate is 30%.

The authors discuss the case of a 76-year-old female patient who has been suffering from subacute cutaneous lupus erythematosus since 1983. In 1999 she was diagnosed with systemic lupus erythematosus (SLE) based on her symptoms of malar rash, polyarthritis, leukopenia, autoimmune hemolytic anemia and positive anti-DNA antibody test. For this she received methylprednisolone and cyclophosphamide. After 3 years of remission, symptoms of cutaneous vasculitis appeared in 2004, which transitionally responded to treatment with azathioprin and methylprednisolone. Her cutaneous symptoms, however, progressed quickly along with generalized lymphadenopathy, splenomegaly and thrombocytopenia. Immunohistological evaluation of the lymph node biopsy showed diffuse large B-cell lymphoma. She developed complete remission after treatment with six-cycle R-CHOP (rituximab, and reduced doses of cyclophosphamide, vincristin, adriablastin, methylprednisolone). SLE became inactive and her symptoms of vasculitis resolved. The authors are bringing attention to one of the possible late complications of systemic lupus, and also underscoring that treatment with rituximab (+CHOP) was beneficial not only for the lymphoma but the SLE as well.

The prevalence, clinical characteristics, and prognostic significance of immune thrombocytopenia (IT) in patients with chronic lymphocytic leukemia (CLL) have not been clearly determined. To clarify this, we retrospectively analyzed 1278 consecutive newly diagnosed patients with CLL. Criteria for IT diagnosis included the following: rapid (< 2 weeks) and severe fall (half of the initial level and below 100 x 10(9)/L) in platelet count; normal or augmented megakaryocytes in bone marrow; no or limited (not palpable) splenomegaly; no cytotoxic treatment in the preceding month. Sixty-four patients (5%) were diagnosed with IT. The median time to IT from CLL diagnosis was 13 months (range, 0-81 months), and median platelet count at IT diagnosis was 14 x 10(9)/L (range, 1-71 x 10(9)/L). Fifty-six of the 64 patients (87%) received treatment for IT. The probability of responding to treatment for IT was significantly higher for patients receiving chemotherapy with or without steroids than for patients treated with intravenous immunoglobulins with or without steroids (P = .01). The development of IT was significantly associated with unmutated IgVh, a positive direct antiglobulin test, and the occurrence of autoimmune hemolytic anemia. Patients with CLL and IT had poorer survival than other patients with CLL (5-year overall survival 64% vs 82%, P < .001), and this effect was independent from common clinical prognostic variables.

A 51-year-old woman, who presented with dyspnea on effort and was diagnosed with autoimmune hemolytic anemia in July 2004, was suspected of having splenic marginal zone lymphoma (SMZL) because of clonality of B cell on bone marrow and splenomegaly. She underwent splenectomy, and histopathological examination of the resected specimen confirmed the diagnosis of SMZL. The patient was treated with rituximab, and complete remission was achieved. Up to the present, three years after diagnosis, the patient has shown no evidence of progression.

Hereditary spherocytosis (HS) is a genetic disorder of the red blood cell membrane clinically characterized by anemia, jaundice and splenomegaly. Evans' syndrome is a clinical syndrome characterized by autoimmune hemolytic anemia (AIHA) accompanied by immune thrombocytopenic purpura (ITP). It results from a malfunction of the immune system that produces multiple autoantibodies targeting at least red blood cells and platelets. HS and Evans' syndrome have different mechanisms of pathophysiology one another. We reported the quite rare case of an infant who had these diseases concurrently. Possible explanations of the unexpected complication are discussed.

Autoimmune manifestations are increasingly being recognized as a component of several forms of primary immunodeficiencies (PID). Defects in purging of self-reactive T and B cells, impaired Fas-mediated apoptosis, abnormalities in development and/or function of regulatory T cells, and persistence of immune activation as a result of inability to clear infections have been shown to account for this association. Among autoimmune manifestations in patients with PID, cytopenias are particularly common. Up to 80% of patients with autoimmune lymphoproliferative syndrome (ALPS) have autoantibodies, and autoimmune hemolytic anemia and immune thrombocytopenia have been reported in 23% and 51% of ALPS patients, and may even mark the onset of the disease. ALPS-associated cytopenias are often refractory to conventional treatment and represent a therapeutic challenge. Autoimmune manifestations occur in 22% to 48% of patients with common variable immunodeficiencies (CVIDs), and are more frequent among CVID patients with splenomegaly and granulomatous disease. Finally, autoimmune cytopenias have been reported also in patients with combined immunodeficiency. In particular, autoimmune hemolytic anemia is very common among infants with nucleoside phosphorylase deficiency. While immune suppression may be beneficial in these cases, full resolution of the autoimmune manifestations ultimately depends on immune reconstitution, which is typically provided by hematopoietic cell transplantation.

We present the case of a 65 years old male, admitted in the Hematology Department of the Universitary Emergency Hospital Bucharest, complaining of physical asthenia and weight loss; periodical medical examination has revealed splenomegaly and leucocytosis with lymphocytosis, persistent for the past 3 years. The clinical and paraclinical exam demonstrated splenomegaly (21 cm in diameter on computer tomography scan), hepatomegaly and generalized lymphadenopathies. The laboratory tests confirmed leucocytosis with lymphocytosis--a clonal population of B lymphocytes CD20+ CD19+ CD23+/- CD79b+(low), CD43+ FMC7+ CD5+ CD38+ ZAP70+ cyclin D1-. Lymph node and bone marrow biopsy together with flowcytometry established the diagnosis of Malignant non-Hodgkin Lymphoma--Atypical Splenic Marginal Zone B-cell lymphoma (aberrant expression of CD5) stage IVB, with leukemic picture, complicated with autoimmune hemolytic anemia with highly positive Coombs' tests. We performed therapeutic splenectomy, which was difficult because of the dimensions of the organ. The short term evolution was complicated by acute complete thrombosis of the splenic vein, but the long term evolution (1 year follow-up) was favorable--remission of anemia, significant improvement of performance status, decrease of leucocytosis and reduction of the tumoral mass.

Patients with autoimmune lymphoproliferative syndrome (ALPS) have defective lymphocyte apoptosis with increased risk for lymphoid malignancies. Herein, we report a patient with ALPS who developed histiocytic sarcoma in a background of sinus histiocytosis and massive lymphadenopathy or Rosai- Dorfman disease. This patient had documented ALPS type Ia with a germline missense mutation in exon 9 of the TNFRSF6 gene (973 A>T, D244V) encoding Fas (CD95/Apo-1). He presented at 10 months with hepatosplenomegaly and autoimmune hemolytic anemia and was diagnosed with ALPS. At the age of 6 (1/2) years, he developed classic Hodgkin lymphoma which was treated using standard chemotherapy. Two years later, a biopsy of a positron emission tomography-positive axillary node showed features of ALPS and focal involvement by sinus histiocytosis and massive lymphadenopathy. Thereafter, the patient continued to have continued lymphadenopathy and progressive splenomegaly, leading to exploratory surgery at the age of 13 years for suspicion of lymphoma. Para-abdominal nodes revealed sheets of malignant- looking histiocytes with increased mitotic activity and areas of necrosis, indicative of histiocytic sarcoma. Spleen and lymph nodes also showed involvement by Rosai-Dorfman disease. Both components had an identical phenotype of S-100+/CD68+/ CD163+. The occurrence of malignancies involving 2 separate hematopoietic lineages in ALPS has not been reported earlier. Given the central role of defective Fas signaling in ALPS, histiocytes may be yet another lineage at risk for neoplastic transformation secondary to a block in apoptosis.

The response rates and overall survival of hairy cell leukemia has changed remarkably with cladribine. Twenty patients diagnosed as hairy cell leukemia over a 5 year period were evaluated. Median age of the patients was 52.5 years. Splenomegaly was seen in 85% and hepatomegaly in 50% patients. At presentation, pancytopenia was seen in 45% and bicytopenia in 20% patients. Tartrate resistant acid phosphatase was positive in 73.68%. Cladribine was given in 13 patients. Overall survival was 84.6%. Median duration of follow-up was 17 months (4-108 months). Direct Coombs' test positive autoimmune hemolytic anemia was seen in two patients (15.38%) on cladribine therapy who required treatment with steroids.
