Abstract
SETTING Kinshasa, Democratic Republic of Congo. OBJECTIVE To identify programmatic interventions for improved survival in patients receiving treatment for tuberculosis (TB) at primary care clinics. DESIGN Retrospective cohort of adult patients initiating anti-tuberculosis treatment between January 2006 and May 2007. RESULTS Among 5685 patients, 390 deaths occurred during anti-tuberculosis treatment, of which half (52%) did so during the first 2 months. Patients with smear-negative pulmonary TB were at greater risk of death in the first 2 months of treatment (human immunodeficiency virus [HIV] positive HR 1.49, 95%CI 0.89-2.49; HIV-negative HR 1.77 95%CI 1.06-2.95), but not thereafter. Patients with extra-pulmonary TB were at increased risk of death in the first 2 months of anti-tuberculosis treatment if they were non-HIV-infected (HR 2.42, 95%CI 1.52-3.85), and were half as likely to die during the remainder of treatment (HIV-positive HR 0.46, 95%CI 0.22-0.97; HIV-negative HR 0.47, 95%CI 0.23-0.94). Antiretroviral therapy (ART) reduced the risk of death by an estimated 36% (HR 0.64, 95%CI 0.37-1.11). CONCLUSION High mortality in the first months of anti-tuberculosis treatment could be reduced by addressing diagnostic delays, particularly for extra-pulmonary and smear-negative TB cases and, in HIV-infected patients, by initiation of ART soon after starting anti-tuberculosis treatment.

Abstract
Objectives:To assess subclinical central nervous system (CNS) involvement in primary Sjögren syndrome (pSS), by comparing standard brain MRI, in-depth neuropsychological testing and 99mTc-ECD brain single-photon emission computed tomography (SPECT) of patients with pSS with matched controls.Methods:10 women (<55 years old), with pSS defined using European–American criteria, presence of anti-SSA and/or anti-SSB antibodies and no history of neurological involvement were prospectively investigated, and compared with 10 age- and sex-matched controls. All subjects underwent, within 1 month, brain MRI, neuropsychological testing, including overall evaluation and focal cognitive function assessment, and 99mTc-ECD brain SPECT.Results:99mTc-ECD brain SPECT abnormalities were significantly more common in patients with pSS (10/10) than controls (2/10; p<0.05). Cognitive dysfunctions, mainly expressed as executive and visuospatial disorders, were also significantly more common in patients with pSS (8/10) than controls (0/10; p<0.01). Notably, between-group comparisons enabled a significant correlation to be established between neuropsychological assessment and 99mTc-ECD brain SPECT abnormalities in patients with pSS (rs = 0.49, p<0.01). MRI abnormalities in patients and controls did not differ significantly.Conclusions:Neuropsychological testing and 99mTc-ECD brain SPECT seem to be the most sensitive tools to detect subclinical CNS dysfunction in pSS. The strong correlation between cortical hypoperfusion in 99mTc-ECD brain SPECT and cognitive dysfunction suggests an organic aetiology of CNS dysfunction in pSS. These data should be confirmed in a larger study.

Abstract
Objective:To characterise major infectious complications and analyse potential risk factors in patients with Wegener granulomatosis (WG).Methods:Data from 113 patients with WG (69 male) followed at least once between January 1984 and March 2006 in our internal medicine department, were analysed retrospectively.Results:A total of 35 patients (mean (SD) age at WG diagnosis: 50.2 (13.05) years) developed 53 major infections. Infections were: bronchopneumonias (n = 19), herpes zoster recurrences (n = 9), cellulitis (n = 4), prostatitis (n = 4), spondylodiscitis and septic arthritis (n = 3), digestive tract infections (n = 2), Enterococcus faecalis or Staphylococcus aureus septicaemia (n = 2), viral hepatitis B reactivations (n = 2), post transfusion HIV infection with fatal cerebral toxoplasmosis, oesophageal candidiasis, disseminated herpes simplex and cytomegalovirus infection, cytomegalovirus retinitis, herpetic keratitis, herpetic stomatitis, Serratia sp. node suppuration and fever resolving under broad spectrum antibiotics (n = 1 each). Half of the major infectious episodes occurred within 3 years after WG diagnosis. Eight (7%) patients died, with two (2%) infection-related deaths. Patients diagnosed with WG before 1996 had a significantly higher rate of infection than those diagnosed later (48% vs 24%, p = 0.02). Cyclophosphamide and corticosteroids were independently associated with significantly higher risk of major infection (p<0.05 and <0.001, respectively). All patients treated since 1993 received antipneumocystosis prophylaxis.Conclusion:Cyclophosphamide and corticosteroids were associated with higher risk of infection. Despite systematic cotrimoxazole prophylaxis, major infections, mostly bronchopneumonias and herpes zoster recurrences, were still common in the course of WG.

Abstract
BACKGROUND Leptin is a secreted adipocyte hormone that plays a key role in the regulation of body weight homeostasis. The leptin effect on human white adipose tissue (WAT) is still debated. OBJECTIVE The aim of this study was to assess whether the administration of polyethylene glycol-leptin (PEG-OB) in a single supraphysiological dose has transcriptional effects on genes of WAT and to identify its target genes and functional pathways in WAT. MATERIALS AND METHODS Blood samples and WAT biopsies were obtained from 10 healthy nonobese men before treatment and 72 h after the PEG-OB injection, leading to an approximate 809-fold increase in circulating leptin. The WAT gene expression profile before and after the PEG-OB injection was compared using pangenomic microarrays. Functional gene annotations based on the gene ontology of the PEG-OB regulated genes were performed using both an 'in house' automated procedure and GenMAPP (Gene Microarray Pathway Profiler), designed for viewing and analyzing gene expression data in the context of biological pathways. RESULTS Statistical analysis of microarray data revealed that PEG-OB had a major down-regulated effect on WAT gene expression, as we obtained 1,822 and 100 down- and up-regulated genes, respectively. Microarray data were validated using reverse transcription quantitative PCR. Functional gene annotations of PEG-OB regulated genes revealed that the functional class related to immunity and inflammation was among the most mobilized PEG-OB pathway in WAT. These genes are mainly expressed in the cell of the stroma vascular fraction in comparison with adipocytes. CONCLUSION Our observations support the hypothesis that leptin could act on WAT, particularly on genes related to inflammation and immunity, which may suggest a novel leptin target pathway in human WAT.

Abstract
PURPOSE Cyclophosphamide in monthly intravenous bolus is used to treat severe forms of systemic sclerosis with pulmonary involvement. Since 1996, cyclophosphamide therapeutic intensification with autologous haematopoietic stem cells transplantation allowed significant improvement in skin and functional scores in severe systemic sclerosis. Cyclophosphamide potential cardiotoxicity in this setting has been questioned. METHODS To analyse cyclophosphamide potential cardiopulmonary toxicity (as graded with WHO classification), we retrospectively studied all severe systemic sclerosis patients treated with cyclophosphamide either during autologous haematopoietic stem cells transplantation procedure (group A) or intravenous cyclophosphamide (group B) recruited in 7 French centers volunteers for the study. Parameters to evaluate heart and lung functions at inclusion, then at last follow-up between 6 and 12 months after start of treatment, were compared using the Mann-Whitney test. RESULTS (Mean+/-standard deviation): Groups A (N=14) and B (N=13) were similar at the beginning of the study in terms of skin, renal, heart and lung involvement. Cyclophosphamide total dose (/m(2)) received in group A was superior (P=0.02) to the one in group B. After respective follow-up of 10+/-2.8 (group A) and 9.9+/-2.7 (group B) months, cyclophosphamide cardio toxicity (group A: N=3; group B: N=2), evolution of the left ventricular ejection fraction and arterial and pulmonary pressures did not differ in the two groups. CONCLUSION In spite of higher cyclophosphamide doses during autologous haematopoietic stem cells transplantation than bolus treatment, cardiopulmonary toxicity appeared not increased. The ongoing European ASTIS trial will compare the respective benefits of these 2 cyclophosphamide regimens in severe Systemic sclerosis.
