Abstract
With a growing number of patients receiving immunosuppressive drugs, lung specialists are faced with new problems. This review addresses: 1: specific interactions between some pre-existing respiratory diseases (asthma, bronchiectasis, infiltrative lung disease, repeated pneumonia, etc) and immunosuppressants; 2: some particular issues in the care of respiratory complications (infections, thoracic surgery, neoplasia, thromboembolism, etc) in patients undergoing immunosuppressive treatment.

Abstract
A 15-month-old boy treated with amoxicillin and clavulanic acid therapy for 8 days was admitted for persistent gastroenteritis and fever. He received ceftriaxone for pneumonia modified on day 4 for cefotaxime and josamycin due to extension of alveolar lesions. On day 7, persistent fever and worsened respiratory distress led to addition of rifampicin. The child was then admitted to an intensive care unit. A hemophagocytic syndrome was suspected based on clinical signs and laboratory findings and confirmed by cytological examination of bone marrow. Adenovirus type 7 was identified by polymerase chain reaction and culture of bronchoalveolar fluid. Prognosis was good within 3 weeks. B and T immunologic evaluations were normal 5 months after the infection. This case of severe adenovirus pneumonia was associated with hemophagocytic syndrome in a child without identified primary immunodeficiency. Adenovirus type 3 and 7 are most frequently responsible for severe or fatal respiratory infections.

Abstract
Nonclassical human leukocyte antigen (HLA)-G and -E loci are separated by approximately 660 kb on the short arm of chromosome 6. Interestingly, some functional and expression characteristics are relatively identical or associated for both molecules. For example, expression of HLA-E on the cell surface has been linked to preferential binding of nonameric leader peptides derived from the signal sequence of HLA-G. It has been suggested that these two molecules act synergistically in modulating susceptibility to infectious or chronic inflammatory diseases. A possible explanation for these observations is that HLA-E and HLA-G are evolving under analogous selective pressures and have functions that place them under selective regimes differing from classical HLA genes. The purpose of this study was to investigate the consistency of this hypothesis based on the characterization of the molecular polymorphism of these two genes and their linkage disequilibrium (LD) in three populations, i.e. Southeastern French (n = 57), Teke Congolese (n = 84) and Tswa Pygmies (n = 74). Allelic frequencies observed for HLA-G and HLA-E and for 14-bp ins/del polymorphism in the three populations were similar to those observed in the literature for populations from corresponding geographic areas. Only one of the recently described HLA-G polymorphisms (HLA-G*01:07-01:16) was found, i.e. HLA-G*01:15 in one individual from Congo. We showed that two haplotypes in Tswa Pygmies, i.e. HLA-G*01:04-E*01:03:01 and G*01:04-E*01:01, exhibited highly significant positive and negative D' values respectively. Although these LD could have functional implications, it is more likely because of the genetic drift as the two other populations did not display any significant LD.

Abstract
Three major types of rearrangements are involved in acute myeloid leukemias (AML): t(8;21)(q22;q22), inv(16)(p13q22), and 11q23/MLL abnormalities. Their precise identification becomes essential for diagnosis, prognosis, and therapeutic choices. Resulting fusion transcripts (FT) are also powerful markers for monitoring the efficacy of treatment, the minimal residual disease (MRD) and could become therapeutic targets. Today, the challenge is to propose an individual follow-up for each patient even for those with a rare fusion event. In this study, we propose a biochip-based assay integrated in a global strategy for identification of rare FT in AML, after fluorescence in situ hybridization detection, as described by the World Health Organization classification. Using cell lines, we developed and validated a biochip-based assay called the AMLFusionChip that identifies every FT of AML1-ETO, CBFbeta-MYH11 as well as MLL-AF9, MLL-ENL, MLL-AF6, and MLL-AF10. The original design of our AMLFusionChip.v01 enables the identification of these FT wherever the breakpoint on the partner gene may be. In case of biochip negative result, our 3'RACE amplification strategy enables to clone and then sequence the new translocation partner. This AMLFusionChip strategy fits into the concept of personalized medicine for the largest number of patients.

Abstract
X-linked lymphoproliferative disease (XLP) is an inherited immunodeficiency, partially characterized by a defect in cytotoxicity to Epstein-Barr virus. This viral infection is therefore often fatal in affected boys, whilst a variety of immune disorders or proliferative diseases may occur in surviving patients. We report an atypical case of a 41year-old male who presented with a primitive B-cell cerebral lymphoma, revealing an XLP. This presentation was unusual because of its late onset, the broad spectrum of the familial characteristics, its initial presentation as a cerebral lymphoma, and the occurrence of B-cell alymphocytosis associated with a-gamma-globulinemia.

Abstract
The mechanical behaviour of adherent cells cultured in vitro is known to be dependent on the mechanical properties of the substrate. We show that this mechanical behaviour is also strongly affected by the cells' environment. We focus here on the impact of temperature and pH. Experiments carried out on individual cells in a tuneable environment reveal that the intra-cellular mechanical behaviour exhibits large and fast changes when the external cell environment is changed. Fast passive microrheometry measurements allow for the precise characterisation of the transient regime observed during a temperature drop. When maintained at a non-physiological temperature, the cells reach a stabilised state distinct from the state observed in physiological conditions. The perturbation can be reversed but exhibits hysteretic behaviour when physiological conditions are restored. The transient regime observed during the recovery process is found to be different from the transient regime observed when leaving physiological conditions. A modified generalized Stokes-Einstein equation taking into account the cell activity through an effective temperature is proposed here to fit the experimental results. Excellent agreement between the model and the measurements is obtained for time lags from 10⁻³ to 1 s considered in this study.

Abstract
Gd and Eu complexes of PMN-tetraacetic acid show interesting properties either for MRI or for optical imaging; that is, for the Gd-complex, a high proton relaxivity with favorable water residence time; for the Eu-complex, a luminescence lifetime of 400 micros at room temperature compatible with the use of time-resolved luminescence technique. Both complexes have a good stability in physiological medium.

Abstract
This study has investigated quantification of chimerism in sex-mismatched transplantations by quantitative real time PCR (RQ-PCR) using FTA paper for blood sampling. First, we demonstrate that the quantification of DNA from EDTA-blood which has been deposit on FTA card is accurate and reproducible. Secondly, we show that fraction of recipient cells detected by RQ-PCR was concordant between the FTA and salting-out method, reference DNA extraction method. Furthermore, the sensitivity of detection of recipient cells is relatively similar with the two methods. Our results show that this innovative method can be used for MC assessment by RQ-PCR.

Abstract
BACKGROUND Health-related quality of life (HRQoL) has been rarely evaluated as a primary endpoint in the assessment of the effect of probiotics on the irritable bowel syndrome (IBS). AIM To study the effects of fermented milk containing Bifidobacterium animalis DN-173 010 and yoghurt strains on the IBS in a multicentre, double-blind, controlled trial. METHODS A total of 274 primary care adults with constipation-predominant IBS (Rome II) were randomized to consume for 6 weeks either the test fermented milk or a heat-treated yoghurt (control). HRQoL and digestive symptoms were assessed after 3 and 6 weeks on an intention-to-treat population of 267 subjects. RESULTS The HRQoL discomfort score, the primary endpoint, improved (P < 0.001) in both groups at weeks 3 and 6. The responder rate for the HRQoL discomfort score was higher (65.2 vs. 47.7%, P < 0.005), as was the decrease in bloating score [0.56 +/- (s.d.)1.01 vs. 0.31 +/- 0.87, P = 0.03], at week 3 in the test vs. the control group. In those subjects with <3 stools/week, stool frequency increased (P < 0.001) over 6 weeks in the test vs. control group. CONCLUSIONS This study suggests a beneficial effect of a probiotic food on discomfort HRQoL score and bloating in constipation-predominant IBS, and on stool frequency in subjects with <3 stools/week.

Abstract
Nontuberculous mycobacterial infections are rare in immunocompetent children, and usually present as adenitis. We report a case of a 6-year-old girl with a multifocal chronic osteomyelitis and pulmonary localisation due to Mycobacterium intracellulare associated with an autosomal dominant mutation of interferon gamma receptor 1 gene (INFGR1) leading to a syndrome of mendelian predisposition to mycobacteria infections by partial deficiency of intracellular signalisation of gamma interferon. This child has been cured with anti-mycobacteria drugs and gamma interferon. This report focus on the importance of looking for a susceptibility of the host to infectious diseases, which can lead to a specific treatment. As far as we know, this is the first case described in a tropical area.

Abstract
This paper presents a liquid surface biosensor whose potential applications are analogue to the well-known quartz crystal microbalance. The technique involved is based on the resonance of meniscus capillary waves here excited at a functionalized air-water interface. The strategy proposed in this paper can be seen as a promising way to avoid as much as possible any transfer of Blodgett type. Meniscus capillary waves supplied by the electrodynamical vibration of a brimful cylinder filled with water are used as a way to characterize the surface aging of an air-water interface covered by a lipidic monolayer. An optical technique based on one-dimensional interferometry is developed to measure continuously the resonant behavior of the surface elevation at the center of the cell around the natural frequencies of the meniscus waves. The frequency dependence of the wave amplitude is investigated during the transient regime associated to the immobilization of DNA strands at the lipidic matrix. Resonant frequencies are found to be very sensitive to the chemical loading supported by the air-water interface. The technique is seen as a mean to discriminate between single- and double-stranded DNA.

Abstract
Ghosal hemato-diaphyseal dysplasia is a rare autosomal recessive disorder characterized by a progressive sclerosing diaphyseal dysplasia and refractory anemia. The pathogenesis and genetic bases of this syndrome remain hitherto unknown. We have performed a genome wide search in two inbred families originating from Algeria and Tunisia. Here, we report on the mapping of a disease gene to chromosome 7q33-34 (Zmax = 4.21 at theta = 0 at locus D7S2513) in a 3.4 Mb defined by loci D7S2560 and AC091742. Ongoing studies will hopefully lead to identification of the disease-causing gene.

Abstract
Adult patients with acute lymphoblastic leukemia (ALL) and t(1;19)/E2A-PBX1 or t(4;11)/MLL-AF4 have a poor outcome. We have evaluated the impact of an intensified post-remission therapy using a high-dose chemotherapy course followed by allogeneic or autologous SCT on the outcome of 58 patients with t(1;19)/E2A-PBX1 (E2A group, n=24) or t(4;11)/MLL-AF4 (MLL group, n=34) treated in the LALA-94 multicenter prospective study. Patients in the MLL group had higher WBC counts and more frequent DIC. CR rates achieved by MLL and E2A groups were similar to other B-cell ALL (87, 82 and 86% respectively). While in CR, patients with a donor were assigned to alloSCT (n=22), the remaining patients with were randomized between autoSCT (n=15) or chemotherapy (n=8). Five-year overall survival was 31 and 45% for E2A and MLL groups, respectively. In both groups, DFS was higher in the alloSCT arm as compared to autoSCT and chemotherapy arms. The results of this study show that chemotherapy intensification did not overcome the poor prognosis of adults with t(1;19)/E2A-PBX1. Allogeneic SCT should thus be offered in first CR to patients with t(1;19)/E2A-PBX1 or t(4;11)/MLL-AF4. New therapeutic approaches are needed for patients without donor.

Abstract
The aim was to evaluate the "strategical place" of the new commercial test Chlamylege (Argene-Biosoft-France) which allows the simultaneous detection in respiratory samples of Chlamydophila pneumoniae, Mycoplasma pneumoniae and most Legionella species using a PCR multiplex. 41 patients with an atypical pneumonia were included, all standard procedures of diagnosis were done and in addition the chamylege test. A pathogen was identified in 12 patients, an other microorganisms than the 3 targeted by our study was found in 8 patients. 4 positive PCR were obtained, 3 with M. pneumoniae and 1 with Legionella pneumophila 1. That means that for 29 patients no aetiology was found. Among them 23 clearly improved under antibiotic treatment. Though that PCR multiplex is an attractive test, easy to perform, sensitive, specific and convenient, we need further studies to approach the place of this PCR test in the diagnosis of multifaceted atypical pneumonia. We also need to know if the cost associated with the microbiological diagnosis (culture, serology, immunofluorescence, urinary antigen test, PCR...) for atypical pneumonia worth value? An algorithm as to be drawn to determine the value of intensive microbiological investigation. An other point to discuss, may be this kind of rapid and multiplex PCR technique could lead to spare the use of some antibiotics.

Abstract
Adenovirus infections result in significant morbidity and mortality in allogeneic haematopoietic stem cell transplanted (hSCT) children. Adenovirus from species C and B account for more than 90% of adenoviruses recovered after hSCT. However, infections due to adenovirus A31 have been increasingly reported in recent years. Between April 2002 and April 2005, blood samples obtained every 2 weeks from 58 hSCT children were screened for adenovirus species A to C by quantitative real-time PCR. Phylogenetic analysis was realized after amplification and sequencing of the entire hexon gene. Fifteen cases of adenovirus infection with viraemia were recovered during this 3 years period. During spring/summer 2003, seven cases occurred and were due to an adenovirus species A. Phylogenetic analysis of the seven strains showed that they belonged to the A31 genotype and shared 100% homology. Clinical features of the seven HSCT children with A31 adenovirus viraemia are described. We describe here an epidemic spread of adenovirus genotype A31 in a paediatric haematology unit. Timing, location and hexon gene genotyping results highly suggested a nosocomial origin to this epidemic. The burden of adenovirus A31 infection needs to be further assessed in this context.

Abstract
Killer-cell immunoglobulin-like receptors (KIRs) expressed by natural killer cells are cell surface molecules able to recognize groups of HLA class I alleles. The number and distribution of KIR genes vary among individuals and populations. The aim of this study is to analyse the KIR gene content in a Comorian population in order to investigate genetic relationships with other populations and to reconstruct past migration events. The Comorian population consisted of 54 unrelated immigrants living in France and a control population consisted of 38 individuals from Southeast France. We investigated the presence or absence of 15 KIR genes, two pseudogenes expressed and non-expressed forms of KIR2DL5 and the two major subtype full-length and deleted forms of KIR2DS4. All individuals were typed positive for the framework genes, i.e. KIR2DL4, KIR3DL2 and KIR3DL3, and the two pseudogenes KIR3DP1 and KIR2DP1. The frequencies of full-length KIR2DS4 (*00101/00102/002) were lower in the French population (F = 29%) than in the Comorian population (F = 72%) (P(c) < 0.05). No significant differences were found for other KIR genes. A total of 11 genotypes were identified in the Southeast French population and 22 genotypes in the Comorian population. The most common genotype (2DL1, 2DL3, 2DL4, 3DL1, 3DL2, 3DL3 and 2DS4) accounted for 41% in the Comorian population and 34% in the Southeast French population. Principal component analysis using KIR gene data from 20 populations was performed to determine genetic differences and relations between populations. The Comorian population exhibited closest kinship with Africans and Asians. As KIR gene content is heterogeneous among ethnic groups, it can probably be used to assess the genetic relationships among populations from different geographic areas.

Abstract
INTRODUCTION The diagnosis of diffuse intra-alveolar haemorrhage (DAH) is suggested by the combination of haemoptysis, anaemia and pulmonary infiltrates. Broncho-alveolar lavage produces macroscopically haemorrhagic fluid and/or haemosiderin laden macrophages. The diagnostic approach should allow distinction between immune mediated and other causes on account of the therapeutic implications. BACKGROUND The main immunological causes are small and medium vessel vasculitis (Wegener's granulomatosis, microscopic polyangeitis), lupus and Goodpasture's syndrome. Other immune disorders are only rarely involved. The association of DAH with an acute glomerulonephritis, indicating the pulmonary-renal syndrome, extra-thoracic involvement and immunological abnormalities suggest an immune aetiology. Immunosuppressant treatment should be started as soon as possible with corticosteroids often combined with intravenous cyclophosphamide. Plasmapharesis is indicated for Goodpasture's syndrome and poorly responding lupus. Aggravating factors such as hypervolaemia and disorders of haemostasis should be searched for and treated. Hospital mortality is close to 20%. VIEWPOINT AND CONCLUSION Immune mediated DAH is a disorder whose rarity justifies the establishment of a national registry with the aim of developing standardised diagnostic and therapeutic strategies.
