Abstract
BACKGROUND Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma, with median age at diagnosis in the seventh decade. FL in young adults (YAs), defined as diagnosis at ≤40 years, is uncommon. No standard approaches exist guiding the treatment of YA FL, and little is known about their disease characteristics and outcomes. To gain further insights into YA FL, we analyzed the National LymphoCare Study (NLCS) to describe characteristics, initial treatments, and outcomes in this population versus patients aged >40 years. PATIENTS AND METHODS Using the NLCS database, we stratified FL patients by age: 18-40 (YA), 41-60, 61-70, 71-80, and >80 years. Survival probability was estimated using Kaplan-Meier methodology. We examined associations between age and survival using hazard ratios and 95% confidence intervals (CIs) from multivariable Cox models. RESULTS Of 2652 eligible FL patients in the NLCS, 164 (6%) were YAs. Of YA patients, 69% had advanced disease, 80% had low-grade histology, and 50% had good-risk disease according to the Follicular Lymphoma International Prognostic Index (FLIPI). Nineteen percent underwent observation, 12% received rituximab monotherapy, and 46% received chemoimmunotherapy [in 59% of these: R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone)]. With a median follow-up of 8 years, overall survival (OS) at 2, 5, and 8 years was 98% (95% CI 93-99), 94% (95% CI 89-97), and 90% (95% CI 83-94), respectively. Median progression-free survival (PFS) was 7.3 years (95% CI 5.6-not reached). CONCLUSIONS In one of the largest cohorts of YA FL patients treated in the rituximab era, disease characteristics and outcomes were similar to patients aged 41-60 years, with favorable OS and PFS in YAs. Longer-term outcomes and YA-specific survivorship concerns should be considered when defining management. These data may not support the need for more aggressive therapies in YA FL. CLINICAL TRIAL NUMBER Roche/Genentech ML01377 (U2963n).

Abstract
New applications are always being developed for immunoglobulins; new recommendations are regularly published. We wished to know the indications used in a large hospital. A hundred and thirty-six adult patients were prescribed immunoglobulins from January to December 2008. Three preparations in intravenous immunoglobulins were available (one liquid, 2 freeze-dried). Fourteen charts were rejected for clerical errors. A hundred and twenty two charts were available for statistical study. Thirty-six patients were on immunoglobulins for antibody deficiency, 19 were followed in haematology for chronic lymphoid leukaemia or multiple myeloma, 19 were treated after lung transplantation, 17 had received a kidney transplant, 1 after heart transplantation: these indications were substitution. Twenty for Guillain Barré and chronic demyelinating polyneuropathy, 10 in immune thrombocytopenic purpura: this was for immunomodulation. Recommendations were followed by the prescribers; charts were reviewed in March and November 2009. Side-effects were rare. (0.6%) (1).

Abstract
A tired 32-year-old woman complaining of tiredness was referred for work-up of a possible immune deficiency. She had a history of recurrent infections since birth, which usually responded to antibiotics within a few days. Her mother, a nurse, had reported that early charts had disappeared. Munchausen's by proxy was suspected for years. Careful anamnesis indicated possible recurrent fever. Serum IgD levels were high, which led us to suspect Hyper IgD Syndrome. Sequencing of the mevalonate kinase gene revealed 2 mutations, leading to amino acid substitutions: one already described (V3771) and R40W: never reported before. Mevalonate kinase activity was very low in the patient's peripheral blood cells. We used the "Poly Phen" prediction program successfully. Our experiments confirmed the diagnosis of mevalonate kinase deficiency. We used steroids to abort recurrent crises.

Abstract
8530 Background: Low IV doses of veltuzumab, a second-generation anti-CD20 monoclonal antibody with structure-function differences from chimeric rituximab, have shown clinical activity, thus justifying subcutaneous (SC) injections. Methods: A phase I/II study was initiated in patients (pts) with previously untreated or relapsed CD20+ indolent NHL or CLL who received 4 SC injections of veltuzumab 2 weeks apart at dose levels of 80, 160, or 320 mg. Efficacy was assessed by CT-based IWG (NHL) or hematology-based NCI/IWCLL (CLL) criteria 4 and 12 weeks later, with responding pts continuing follow-up. Other evaluations included AEs, safety laboratories, B-cell blood levels (CD19), serum veltuzumab levels, and human anti-veltuzumab antibody (HAHA) titers. Results: Nineteen pts (8M/11F, median age 63), including 14 NHL pts (11 follicular, 3 other indolent NHL; 5 treatment naive) most with stage III or IV disease (11/14) and 5 CLL pts (4 treatment naïve) all with Rai stage II or III disease, have now received SC veltuzumab at 80 mg (3 NHL, 3 CLL), 160 mg (9 NHL, 2 CLL) or 320 mg (2 NHL) dose levels. Pre-treatment with antihistamines or steroids has not been required, and SC veltuzumab was well tolerated with only mild, transient injection site reactions and tenderness. To date, all HAHA results have been negative. In NHL pts, SC veltuzumab demonstrates good bio-availability, with a slow release pattern over several days and depletion of circulating B cells starting after 1st injection. Initial response information is currently available for 10 pts. For 7 NHL pts, 4 weeks after treatment with 80 or 160 mg doses, 2 pts had partial responses, 3 pts showed stable disease, and 2 pts had disease progression. For 3 CLL pts who received 80 mg doses, serum veltuzumab levels were lower, but all pts still achieved 65–75% decreases in circulating leukemic cells over the course of treatment. Conclusions: SC administration of veltuzumab is well tolerated, achieves slow but efficient delivery into the blood, and is pharmacologically active. The low doses currently evaluated in B-cell malignancies show evidence of therapeutic activity, achieving objective responses in NHL and notable reductions in circulating leukemic cells in CLL.

Abstract
PURPOSE Cytomegalovirus (CMV) retinitis is the most common ocular opportunistic infection associated with AIDS. It usually affects the peripheral retina, sparing the macula. We describe an atypical CMV retinitis exclusively confined to the macula. METHODS A 43-year-old man with the diagnosis of AIDS developed a white retinal lesion confined to the macula of the right eye. Two weeks later, a more typical granular appearance was observed leading to presumption of CMV retinitis. RESULTS The patient was treated with ganciclovir without success. With foscarnet, a good response was obtained, leading to total healing of the lesion. CONCLUSIONS CMV retinitis has to be taken into consideration in all lesions confined to the macula in immunodepressed patients. An early diagnosis is crucial to avoid blindness.

Abstract
Physicians of the unit have first taken care of patients with acquired Immunodeficiency in 1981. We have become an independent "Reference Centre" in 1998. The multidisciplinary team follows more than 300 patients on a regular basis. AIDS has been amply publicized, but other immuno-deficiencies have not. Primary immunodeficiencies are "orphan" diseases; they can be as serious, or more severe even, than AIDS. About 60 patients with "PID" are followed by the team. We are involved in research, and have participated in the identification of a mutation of an HIV co receptor that protects against HIV infection. We also studied the pathogenesis of Kaposi's sarcoma, and the immunological basis of adverse reactions to intravenous gammaglobulins.

Abstract
Twelve HIV-1-infected, nine HIV-2-infected patients and eight HIV-negative subjects were given a 40IU booster dose of tetanus toxoid (TT). Blood was collected on days 0, 7 and 30 after immunization. Changes in HIV-1 or HIV-2 RNA load were evaluated by nested PCR. TT-IgG antibody levels were quantified by ELISA. CD4 cell counts as well as activation, memory and maturation markers of T lymphocyte subsets were determined by flow cytometry. The induction of apoptosis was investigated using 7-aminoactinomycin D (AAD) and propidium iodide (PI) staining. Proliferative responses to TT and pokeweed mitogen (PWM) were determined by the level of [(3)H] thymidine incorporation. Seven and 30 days after immunization, there was no detectable increase in HIV-1 or HIV-2 plasma load. There were also no changes in CD4 cell counts, CD69, HLA-DR and memory CD45RO or naive CD45RA antigens. Immunization did not increase the spontaneous apoptosis of peripheral blood mononuclear cells (PBMCs), CD4+ and CD8+ T cells subsets neither in controls nor in HIV-infected patients. Similarly, apoptosis induced in vitro by PWM or by the specific TT recall antigen did not vary during the study period. The proliferative response to PWM and to the TT recall antigen was decreased both in HIV-1- and HIV-2-infected patients compared to HIV-negative controls. Immunization significantly increased the TT-IgG levels in healthy controls and in HIV-infected patients. However, the anti-TT-IgG response, as measured by the fold-increase index between days 0 and 30, was significantly higher in healthy controls than in HIV-1- (P=0.036) and HIV-2-infected patients (P=0.003). In conclusion, we found no deleterious immunologic or virologic effect was detected in healthy HIV-1- and HIV-2-infected individuals after antigenic challenge with a TT booster. However, the response to TT vaccination was lower in HIV-1- and in HIV-2-infected individuals than in healthy HIV-negative controls.

Abstract
Severe primary immunodeficiencies (PID) are rare; their global incidence is comparable to that of childhood leukemia; they include more than 100 different entities. Clinical manifestations are: unusually severe or frequent infections or infections that do not respond to adequate treatment; an increased risk of certain malignancies; sometimes auto-immune manifestations. Delayed diagnosis and management of PID can lead to severe and irreversible complications or to death. PID can become manifest only in the adult; in common variable immune deficiency, the median age at diagnosis is between the 2nd and the 3rd decade of life. PID are often transmitted genetically; recent progresses in molecular biology have allowed more precise and earlier, including antenatal, diagnosis. Molecular treatment of 3 infants with a severe immunodeficiency has recently been achieved in April 2000. Those progresses were mostly based on the study of immunodeficiency databases. We present here the work of a Belgian group specialized in PID; meetings have started in June 1997. This group establishes guidelines for the diagnosis and treatment of PID, adapted to the local situation. The elaboration of a national register of PID is also underway; this has to provide all guaranties of anonymity to patients and families. Such a register already exists at the European level; it has provided the basis for new diagnostic and therapeutic possibilities. The inclusion of Belgian data in this register should allow essential progresses essential for our patients.

Abstract
Increased programmed cell death (PCD) or apoptosis has been detected in the T cells of HIV-infected subjects; it is held partially responsible for the continuous loss of CD4+ T cells during the natural course of HIV infection. Highly active antiretroviral therapy (HAART) decreases the viral load and leads to an increase of CD4+ count in vivo. In this study we evaluated PCD in total peripheral blood mononuclear cells, CD8+ and CD4+ lymphocytes before and four weeks after initiation of HAART. Seven HIV-1-infected patients were investigated. Viral load was assessed by RT-polymerase chain reaction and PCD by flow cytometry using apoptosis by 7 amino actinomycin D (7AAD) and propidium iodide (PI). After four weeks of HAART, CD4+ T and CD8+ T cell levels were stable, and plasma HIV-RNA copies were significantly decreased. In four of the patients (4/7), HIV-RNA levels were reduced to undetectable levels (fewer than 400 copies per milliliter). A statistically significant reduction of apoptosis among CD4+ cells was observed (P < 0.03), though neither in the CD8+ T cell population nor in peripheral blood mononuclear cells (PBMCS). These results demonstrate the beneficial effect of HAART on apoptosis of CD4+ cells in the early treatment stage.

Abstract
The role of iron in the pathogenesis of several tumours is being increasingly investigated. In particular, its involvement in the pathogenesis of Kaposi's sarcoma (KS) is suggested by the distribution of the endemic form of KS corresponding to continental rifts and associated iron-oxide-rich volcanic clays. We investigated in vitro to what extent iron supplementation or withdrawal could affect the growth of KS-derived cells, by analysing the effects of adding iron salts (iron chloride and ferric nitrilotriacetate) and/or reducing iron by iron chelators (desferrioxamine) on KS-derived cell cultures. The addition of iron salts strongly stimulated the growth of KS cells, as reflected by increase in thymidine incorporation and cell number. Conversely, desferrioxamine and deferiprone inhibited cell growth. The inhibitory effect of iron chelation was more pronounced on rapidly dividing basic fibroblast-growth-factor-stimulated cells. These results may point to a novel therapeutic approach to KS.

Abstract
Kaposi's sarcoma (KS) is an angioproliferative disease characterized by proliferating spindle-shaped cells, angiogenesis, and inflammatory cell infiltration. Several lines of evidence suggest that KS is a multifocal cytokine-mediated disease of vascular origin. Because metalloproteinases (MMPs) are important enzymes involved in angiogenesis, we studied their activity in five different KS-derived cell lines and compared these data with those obtained with human umbilical vein endothelial cells (HUVEC). We focused on the activity of the 72- and 92-kd type IV collagenases because these enzymes are thought to play an important role in the process of tumoral invasion. Nonstimulated HUVEC released a weak 72-kd collagenase activity and no 92-kd collagenase activity, as determined by zymographic analysis. Stimulation of HUVEC with phorbol myristate acetate (PMA) or TNF-alpha increased the 72-kd collagenase activity and also induced a 92-kd collagenase activity. By contrast, KS-derived cells constitutively released significant 72- and 92-kd collagenase activities. The basal release of these enzymes by KS cells was further enhanced by TNF-alpha or PMA. Conversely after in vivo exposure to chemotherapy, KS-derived cells showed a downregulation of the production of MMPS that could be reversed by the addition of TNF or PMA. These results suggest that KS cells have constitutive features of activated cells that have an invasive and metastasizing potential.

Abstract
We present the case of an asymptomatic HIV carrier, who presented with acute myeloblastic leukemia in third relapse and successfully underwent autologous stem cell transplantation as a rescue treatment. This observation supports the conclusion that tolerance of autologous bone marrow or stem cell transplant in patients with HIV may correlate with a low viral burden and relatively good immune function.

Abstract
A patient with the Acquired ImmunoDeficiency Syndrome (AIDS) treated with a daily low dose of corticosteroids for chronic atopic dermatitis experienced a sudden episode of unilateral knee arthritis. Culture of the purulent synovial liquid yielded a pure culture of Streptococcus Equisimilis. A four week period of intravenous antibiotherapy combined with repeated drainages allowed a complete recovery of articular function.
