Abstract
Background Hereditary angioedema (HAE) is associated with a heavy burden of illness. Objective To evaluate use of lanadelumab in a French Authorization for Temporary Use (ATU) program. Methods ATU requests were made between October 12, 2018, and March 13, 2019; patients were followed through September 23, 2019. At entry, patients received lanadelumab 300 mg every 2 weeks. HAE attack characteristics were evaluated at day (D) 0 and months (M) 3 and 6. Patients completed the Angioedema Quality of Life (AE-QoL) questionnaire at initiation and monthly and the Angioedema Activity Score questionnaire daily in 28 day cycles (AAS28). Results In total, 77 patients received ≥ 1 lanadelumab dose; 69 had ≥ 1 quarterly follow-up visit (analyzed population). Mean (standard deviation [SD]) lanadelumab exposure was 240.4 (53.7) days. Lanadelumab dose was modified in 12 patients (mostly to every 4 weeks). For the analyzed population, compared with attacks/month (mean [SD]) within 6 months before ATU (2.68 [2.54]), fewer attacks occurred between initiation and first visit (0.16 [0.42]; P < 0.001) or last visit (0.16 [0.42]; P < 0.001); D15 and last visit (0.15 [0.41]); and D70 and last visit (0.17 [0.70]). AE-QoL total and domain scores were significantly higher at initiation versus M3 and M6; 55% and 65% of patients, respectively, achieved a minimal clinically important difference from D0 to M3 and D0 to M6. Proportion of patients with AAS28 of 0 was higher during M3 (90%) and M6 (83%) than initiation (59%). The most frequently reported adverse events included headache (7.3%) and injection site pain (6.3%). Conclusions Lanadelumab reduced attack rates, improved quality of life, and was generally well tolerated.

Abstract
We discovered a highly virulent variant of subtype-B HIV-1 in the Netherlands. One hundred nine individuals with this variant had a 0.54 to 0.74 log10 increase (i.e., a ~3.5-fold to 5.5-fold increase) in viral load compared with, and exhibited CD4 cell decline twice as fast as, 6604 individuals with other subtype-B strains. Without treatment, advanced HIV-CD4 cell counts below 350 cells per cubic millimeter, with long-term clinical consequences-is expected to be reached, on average, 9 months after diagnosis for individuals in their thirties with this variant. Age, sex, suspected mode of transmission, and place of birth for the aforementioned 109 individuals were typical for HIV-positive people in the Netherlands, which suggests that the increased virulence is attributable to the viral strain. Genetic sequence analysis suggests that this variant arose in the 1990s from de novo mutation, not recombination, with increased transmissibility and an unfamiliar molecular mechanism of virulence.

Abstract
We assessed bone mineral density (BMD) in a cohort of human immunodeficiency virus (HIV)-positive patients after a median of 11 years of combination antiretroviral therapy (cART) and evaluated the respective role of HIV infection and antiretroviral drugs (ARVs). A cross-sectional study of 162 participants (131 male) from the ANRS-C08 cohort was performed with bone dual-energy X-ray absorptiometry (DXA) scans and renal assessment. The window of exposure to ARVs was defined as an exposure of more than six cumulative months during the last 3 years before the DXA evaluation to account for a cumulative exposure that could affect bone remodeling. The association with low BMD (Z-score < -2) was assessed by a multiple logistic regression model. The study population was 50 years (median), hepatitis C virus (HCV) (18%), and hepatitis B virus (HBV) (8%) coinfection with HIV-RNA <50 c/mL in 89%, median CD4 of 619/mm3. Prevalence of low BMD was 18% in males and 6% in females. The factors associated with a Z-score < -2 in males were uric acid renal loss [adjusted odds ratio (aOR): 6.1; 95% confidence interval (CI): 1.2-31.5; p = .03], HCV coinfection (aOR: 4.0; 95% CI: 1.3-12.2; p = .02), and less frequent window of exposure to nevirapine (NVP) (aOR: 0.1; 95% CI: 0.02-0.6; p = .01). For the full study sample, there was a strong positive association between duration of exposure to NVP and lumbar spine Z-score (p = .004). HIV-positive patients exposed to long-term cART have a high incidence of low BMD. Tenofovir disoproxil fumarate and ritonavir-boosted protease inhibitors did not seem to be associated with increased risk of low BMD, whereas NVP exposure appeared to have an independent positive association.

Abstract
OBJECTIVE Hereditary angiœdema (HAE) is a rare autosomal dominant disease characterized by recurrent, unpredictable, potentially life-threatening swelling. Objective is to assess the management of the acute HAE attacks in the real life setting through a call center in France. METHODS A pre-specified ancillary study of SOS-HAE, a cluster-randomized prospective multicenter trial, was conducted. HAE patients were recruited from 8 participating reference centers. The outcome of interest was the rate of hospitalization. RESULTS onerhundred patients were included. The median (quartile) age was 38 (29-53) years, and 66 (66%) were female. Eighty (80%) patients had HAE type I, 8 (8%) had HAE type II and 12 (12%) patients had FXII-HAE. Fifty-one (51%) patients had experienced at least one time the call center during the follow-up. Nine over 166 (5%) attacks for 9 different patients resulted in hospital admission to the hospital (in the short-stay unit, ie, <24 h) during the follow-up period. During 2 years, there were 166 calls to call center for 166 attacks. All attacks were treated at home after call center contact. CONCLUSIONS Use of emergency departments and hospitalizations are reduced by the use of a coordinated national call center in HAE after therapeutic education program that promoted self-administration of specific treatment and use of call to call center.

Abstract
The efficacy of plasma exchanges (PE) during the course of scleroderma has only been investigated for short periods. The aim of this study was to follow patients over a long enough period to observe the course of the clinical and paraclinical symptoms in the short, medium, and long term. Forty patients, 24 women and 16 men, were treated by PE and observed for 1–3, 3–12 and over 12 months. Immunological, biological and clinical course and any undesirable side effects were evaluated using a detailed questionnaire. Concomitant therapies were reported and most frequently consisted of corticosteroids, colchicine, factor XIII or vasodilators (nifedipine, captopril). The therapeutic effectiveness of PE was assessed on the basis of improvements in cutaneous, digestive, joint, muscular, lung, cardiovascular and renal lesions. Our findings confirmed the effectiveness of short-term PE on scleroderma (52% of the patients improved during the first 3 months). However, this improvement was transient (5% improvement between 3 and 12 months and only 2.5% over 12 months) and limited to the cutaneous and muscular lesions. Thus, PE cannot be recommended for the treatment of progressive systemic sclerosis.

Abstract
BACKGROUND In a context of the evolution of severe morbidities in patients living with HIV (PLWH), the aim of this study was to describe reasons for hospitalization and the mode of care for the patients requiring hospitalization. METHODS All admissions (≥24h) of PLWH to 10 hospitals in the south of Paris (COREVIH Ile-de-France Sud) between 1/1/2011 and 12/31/2011 were identified. The hospital database and the file of patients followed in the HIV referral department of each hospital were matched. Detailed clinical and biological data were collected, by returning to the individual medical records, for a random sample (65% of hospitalized patients). RESULTS A total of 3013 hospitalizations (1489 patients) were recorded in 2011. The estimated rate of hospitalized patients was about 8% among the 10105 PLWH routinely managed in COREVIH Ile-de-France Sud in 2011. The majority (58.5%) of these hospitalizations occurred in a unit other than the HIV referral unit. Non-AIDS-defining infections were the main reason for admission (16.4%), followed by HIV-related diseases (15.6%), hepatic/gastrointestinal diseases (12.0%), and cardiovascular diseases (10.3%). The median length of stay was 5 days overall (IQR: 2-11), it was longer among patients admitted to a referral HIV care unit than to another ward. HIV infection had been diagnosed >10 years previously in 61.4% of these hospitalized patients. They often had associated comorbidities (coinfection HCV/HVB 40.5%, smoking 45.8%; hypertension 33.4%, dyslipidemia 28.8%, diabetes 14.8%). Subjects over 60 years old accounted for 15% of hospitalized patients, most of them were virologically controlled under HIV treatment, and cardiovascular diseases were their leading reason for admission. CONCLUSION Needs for hospitalization among PLWH remain important, with a wide variety in causes of admission, involving all hospital departments. It is essential to prevent comorbidities to reduce these hospitalizations, and to maintain a link between the management of PLWH, that becomes rightly, increasing ambulatory, and recourse to specialized inpatient services.

Abstract
BACKGROUND Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) causes swelling in the skin and upper airways and pain in the abdomen because of mucosal swelling. C1-INH-HAE is frequently misdiagnosed, leading to delays in diagnosis, inadequate treatment, and unnecessary procedures. OBJECTIVE To evaluate the history of misdiagnosis in patients participating in the Icatibant Outcome Survey (IOS). METHODS The IOS is an observational study in which safety and effectiveness of icatibant have been evaluated since 2009. As part of the IOS, patients record any misdiagnoses received before being diagnosed as having C1-INH-HAE. RESULTS In January 2016, a total of 418 of 633 IOS patients with C1-INH-HAE type I or II had provided misdiagnosis data. Of these, 185 of 418 (44.3%) received 1 or more prior misdiagnoses. The most common misdiagnoses were allergic angioedema (103 of 185) and appendicitis (50 of 185). A variety of other misdiagnoses were reported, including a substantial number of gastrointestinal disorders (excluding appendicitis). Misdiagnosis rates were similar between males (41.1%) and females (46.5%) and between C1-INH-HAE type I (43.7%) and type II (51.6%). Patients with family members diagnosed as having C1-INH-HAE were significantly less likely to be misdiagnosed than patients without a family history (140 of 366 [41.7%] vs 38 of 58 [65.5%], respectively; P = .001). Patients with a prior misdiagnosis had longer median delay to C1-INH-HAE diagnosis (13.3 years) than patients without (1.7 years; P < .001). CONCLUSION From this large database, approximately 50% of patients with C1-INH-HAE type I or II have previously had their conditions misdiagnosed, most commonly as allergic angioedema or appendicitis. Misdiagnosis results in marked delays in receiving the correct diagnosis, during which time patients cannot access effective, lifesaving treatment. TRIAL REGISTRATION ClinicalTrials.gov: NCT01034969.

Abstract
Background Despite the availability of guidelines for the specific treatment of hereditary angioedema (HAE) attacks, HAE morbidity and mortality rates remain substantial. HAE attacks are a major medical issue requiring specific treatment as well as a considerable socio-economic burden. We report a protocol designed to test whether a dedicated call centre is more effective than usual practice in the management of patients experiencing an HAE attack. Methods/design This prospective, cluster-randomised, single-blind, parallel-group, multicentre trial evaluates the morbidity and consequent socio-economic costs of the management of patients experiencing an HAE attack by a dedicated call centre as compared to usual practice. The trial aims to recruit 200 patients. Patients in the intervention arm are provided with an SOS-HAE card with the call centre’s freephone number that they can access in the case of an attack. The centre’s mission is to provide recommended expert advice on early home treatment. The centre can route the call to a local emergency medical service with competency in HAE management or even arrange for the drugs needed for the specific treatment of an HAE attack to be sent to the emergency department of the local hospital. The primary outcome measure is the number of hospital admissions for an HAE attack. Each patient will be followed up every 2 months for 2 years. The study has been approved by the ethics committee (Comité de Protection des Personnes d’Ile de France 10; registration number: 2012-A00044-39; date of approval: 19 January 2012). Discussion The SOS-HAE protocol has been designed to address the handling of attacks experienced by patients with HAE in the home. The proposed trial will determine whether the setting up of a dedicated call centre is more effective than usual practice in terms of reducing morbidity as given by the numbers of hospital admissions. The results are also anticipated to have important implications in terms of socio-economic costs for both healthcare services and patients. Trial registration ClinicalTrials.gov NCT01679912.

Abstract
As part of an international intercomparison project, the weak temperature gradient (WTG) and damped gravity wave (DGW) methods are used to parameterize large-scale dynamics in a set of cloud-resolving models (CRMs) and single column models (SCMs). The WTG or DGW method is implemented using a configuration that couples a model to a reference state defined with profiles obtained from the same model in radiative-convective equilibrium. We investigated the sensitivity of each model to changes in SST, given a fixed reference state. We performed a systematic comparison of the WTG and DGW methods in different models, and a systematic comparison of the behavior of those models using the WTG method and the DGW method. The sensitivity to the SST depends on both the large-scale parameterization method and the choice of the cloud model. In general, SCMs display a wider range of behaviors than CRMs. All CRMs using either the WTG or DGW method show an increase of precipitation with SST, while SCMs show sensitivities which are not always monotonic. CRMs using either the WTG or DGW method show a similar relationship between mean precipitation rate and column-relative humidity, while SCMs exhibit a much wider range of behaviors. DGW simulations produce large-scale velocity profiles which are smoother and less top-heavy compared to those produced by the WTG simulations. These large-scale parameterization methods provide a useful tool to identify the impact of parameterization differences on model behavior in the presence of two-way feedback between convection and the large-scale circulation.

Abstract
As part of an international intercomparison project, a set of single-column models (SCMs) and cloud-resolving models (CRMs) are run under the weak-temperature gradient (WTG) method and the damped gravity wave (DGW) method. For each model, the implementation of the WTG or DGW method involves a simulated column which is coupled to a reference state defined with profiles obtained from the same model in radiative-convective equilibrium. The simulated column has the same surface conditions as the reference state and is initialized with profiles from the reference state. We performed systematic comparison of the behavior of different models under a consistent implementation of the WTG method and the DGW method and systematic comparison of the WTG and DGW methods in models with different physics and numerics. CRMs and SCMs produce a variety of behaviors under both WTG and DGW methods. Some of the models reproduce the reference state while others sustain a large-scale circulation which results in either substantially lower or higher precipitation compared to the value of the reference state. CRMs show a fairly linear relationship between precipitation and circulation strength. SCMs display a wider range of behaviors than CRMs. Some SCMs under the WTG method produce zero precipitation. Within an individual SCM, a DGW simulation and a corresponding WTG simulation can produce different signed circulation. When initialized with a dry troposphere, DGW simulations always result in a precipitating equilibrium state. The greatest sensitivities to the initial moisture conditions occur for multiple stable equilibria in some WTG simulations, corresponding to either a dry equilibrium state when initialized as dry or a precipitating equilibrium state when initialized as moist. Multiple equilibria are seen in more WTG simulations for higher SST. In some models, the existence of multiple equilibria is sensitive to some parameters in the WTG calculations.

Abstract
OBJECTIVES The objective of this study was to analyse the respective roles of personal factors and HIV infection markers on the systemic immune activation/inflammatory profile of long-term antiretroviral treatment-controlled patients. PATIENTS AND METHODS A panel of soluble immune activation/inflammatory biomarkers was measured in 352 HIV-infected treatment-controlled patients from the APROCO-COPILOTE cohort, all of whom were started on a PI in 1997-99 and had a final evaluation 11 years later, and in 59 healthy controls. RESULTS A total of 81.5% of the patients were male, with the following characteristics: median age 49 years; 620 CD4 cells/mm(3); 756 CD8 cells/mm(3); CD4/CD8 ratio 0.81; BMI 23.0 kg/m(2); waist-to-hip ratio 0.95. Markers of inflammation-high-sensitivity (hs) IL-6 (median and IQR) (1.3 pg/L, 0.7-2.6), hs C-reactive protein (CRP) (2.1 mg/L, 0.9-4.5) and D-dimer (252 ng/mL, 177-374)-were elevated compared with healthy controls (P < 0.001) and strongly related to each other, as were markers of immune activation [soluble (s) CD14 (1356 ng/mL, 1027-1818), β2-microglobulin (2.4 mg/L, 2.0-3.1) and cystatin-C (0.93 mg/L, 0.82-1.1)]. Inflammatory and immune activation markers were also associated with each other. In HIV-infected patients: age was related to D-dimer, β2-microglobulin and cystatin-C levels; being a smoker was related to increased IL-6 and cystatin-C; and BMI and waist-to-hip ratio were related to CRP. Conversely, markers of HIV infection, current CD4 or CD8 values, CD4 nadir, CD4/CD8 ratio, AIDS stage at initiation of PIs, current viral load and duration of ART were not associated with immune activation/inflammation markers. CONCLUSIONS In these long-term treatment-controlled HIV-infected patients, all systemic markers of inflammation and immune activation were increased compared with healthy controls. This was related to demographic and behavioural factors, but not to markers of severity of the HIV infection. Intervention to decrease low-grade inflammation must thus prioritize modifiable personal factors.

Abstract
Abstract
Columnar cell lesions of the breast are common findings in core biopsies for mammographically indeterminate calcifications. Atypical columnar cell lesions, also referred to as flat epithelial atypia (FEA), confer a mildly increased risk of subsequent carcinoma and are often co-localized with other patterns of atypia. The management of FEA diagnosed on core biopsy remains controversial with studies reporting carcinoma on excisional biopsy in 13 to 67% of cases. We report the frequency of carcinoma in excision specimens after a diagnosis of FEA on core biopsy over a nine year period at Carolinas Medical Center.
Cases were identified from our files for the period from January 2004 through October 2012. Core biopsies with FEA as the most “advanced” lesion were included. Exclusion criteria included another pattern of atypia, carcinoma in situ, or invasive carcinoma in ipsilateral core biopsies performed concurrently or within four months of the core biopsy with FEA alone. The pathology reports for excision specimens following a core biopsy with FEA alone were retrieved. For each core biopsy with pure FEA, the histologic and mammographic findings were correlated.
A total of 116 cases with a diagnosis of FEA on core biopsy were identified. Two (2) cases were ultrasound core biopsies, 1 was MRI-guided, and the remaining 113 cases were stereotactic core biopsies performed for calcifications. FEA was the most advanced lesion in 53 cases (46%), corresponding to 55 core biopsies. In the 63 cases with FEA and a more advanced lesion, 34 (29%) contained atypical ductal hyperplasia, 6 (5%) atypical lobular hyperplasia, 4 (3%) atypical ductal and lobular hyperplasia, 11 (10%) ductal carcinoma in situ, 2 (2%) lobular carcinoma in situ, and 6 (5%) invasive carcinoma. Of the 55 core biopsies with FEA alone, excision pathology reports were unavailable for 11 cases, and an ipsilateral core biopsy contained a more advanced lesion in 6 cases. Of the 38 remaining cases, 4 excision specimens (11%) contained carcinoma and 8 specimens (21%) contained another, higher risk pattern of atypia (atypical ductal hyperplasia or atypical lobular hyperplasia). Excision results are summarized in the table below: 10 (26%) contained no residual atypia, 16 (42%) residual FEA, 7 (18%) atypical ductal hyperplasia, 1 (3%) atypical lobular hyperplasia, 3 (8%) ductal carcinoma in situ, and 1 (3%) invasive carcinoma.

The data from a nine year period at our institution demonstrate an 11% upgrade rate to carcinoma for patients with a diagnosis of FEA on core biopsy. The higher risk patterns of atypia (atypical ductal hyperplasia or atypical lobular hyperplasia) found in 21% of cases also impact risk stratification and future clinical and radiographic follow-up. In total, future clinical management was altered in 32% of patients based on excision specimen results. The findings support performing an excisional biopsy for a core biopsy containing FEA.

Abstract
BACKGROUND Smoking prevalence is very high among people living with HIV/AIDS, and smoking is riskier for them than for HIV-seronegative people. Promoting smoking cessation among HIV-infected people is therefore an emerging public health priority. Raising cigarette prices is usually considered as one of the most effective ways to reduce smoking, but its effectiveness has never been studied among HIV-infected smokers. METHODS We studied the impact of cigarette price increases among HIV-infected smokers, with data extracted from the French cohort study APROCO-COPILOTE conducted between 1997 and 2007 among 1,146 patients. Data regarding respondents' smoking status was collected every 8 months over the first 5 years, and every 12 months thereafter. RESULTS We found striking differences across transmission groups regarding socio-demographic background and smoking prevalence. The Intravenous Drug Use (IDU) group was characterised by a lower socioeconomic status, a higher smoking prevalence and a smaller decrease in this prevalence over the period 1997-2007. The homosexual group had a higher socioeconomic status, an intermediate smoking prevalence in 1997, and the highest rate of smoking decrease. In the dynamic multivariate analysis, smoking remained correlated with indicators of socioeconomic disadvantage and with infection through IDU. Aging and cigarette price increase had a negative impact on smoking among the homosexual group, but not for the IDU group. CONCLUSION Among seropositive people, just as for the general population, poor smokers are poor quitters. Public health authorities should consider interventions which are not smoking-specific, but which contribute to improve the living conditions of the most deprived HIV-infected smokers.

Abstract
BACKGROUND The increase in CD4 count may reach a plateau after some duration of virological response to highly active antiretroviral therapy (HAART). METHODS A total of 1281 HIV-infected patients initiating HAART were enrolled in the AntiPROtease (APROCO) cohort. We investigated determinants of increase in CD4 count using longitudinal mixed models in patients who maintained a plasma HIV RNA <500 HIV-1 RNA copies/mL. RESULTS A total of 870 patients had a virological response at month 4. The median follow-up time was 57 months. Mean estimated increases in CD4 count in patients with persistent virological response were 29.9 cells/muL/month before month 4, 6.4 cells/microL/month between months 4 and 36, and 0.7 cells/microL/month (not significantly different from 0) after month 36. Three factors were associated with a significantly positive CD4 count slope after month 36: male gender (+0.9), no history of antiretroviral therapy at baseline (+1.7) and baseline CD4 count <100 cells/microL (+2.6). In patients who maintained a virological response after 5 years of HAART, a CD4 count >500 cells/microL was achieved in 83% of those with a baseline CD4 count >or=200 cells/microL and in 45% of those with a baseline CD4 count <200 cells/microL. CONCLUSION The increase in CD4 count reaches a plateau after 3 years of virological response. Even if patients initiating HAART with low CD4 counts still show a CD4 count increase after 3 years, it remains insufficient to overcome immune deficiency in all patients.

Abstract
BACKGROUND This study aimed to determine factors associated with higher levels of health related quality of life (HRQL) among individuals HIV-infected through drug injection and to evaluate the impact of injecting drug status and opiate substitution treatment (OST) on HRQL. METHODS Two hundred and forty-three patients, enrolled in the MANIF cohort of patients HIV-infected through IDUs, participated. They completed a self-administered questionnaire, which included an HRQL evaluation (SF-12) and socio-demographic/clinical characteristics at the 42-month visit. Injecting drug status, OST and experience of negative life events (NLE) were collected at any follow-up visit in order to reconstitute individual trajectories. RESULTS Among the 243 patients, 35% reported a normal mental HRQL and 37% a normal physical HRQL. Independent predictors of "normal" mental HRQL were social support from partner, being a former IDU, no experience of violence-related NLE and few self-reported HAART-related side effects. "Normal" physical HRQL was predicted by younger age, stable partner, being a former IDU (> or = 6 months), CD4 cell count > 500, no experience of financial-related NLE and few HAART self-reported side effects. CONCLUSIONS As HRQL has been found to have a prognostic value on the survival of HIV patients infected through drug injection, then providing more comprehensive care (for example by paying more attention to patients' experience of stressful events, meeting their needs in psychosocial support and better management of perceived toxicity) could globally improve treatment outcomes in this vulnerable population.

Abstract
BACKGROUND Efavirenz (EFV) is a highly active antiretroviral drug, use of which is associated with frequent (although transient) neurosensorial adverse reactions. Whether the use of EFV is associated with the risk of depression or suicide remains controversial. METHODS ALIZE-ANRS (Agence Nationale de Recherches sur le SIDA et les Hepatites Virales) 099 was a 48-week randomized trial involving virologically suppressed, human immunodeficiency virus (HIV)-infected patients that compared the maintenance of a treatment regimen that contained protease inhibitors (177 subjects) with a switch to a once-daily combination of EFV, didanosine, and emtricitabine (178 subjects). We used the trial's adverse events reporting system and a self-administered Center for Epidemiologic Studies-Depression Scale questionnaire to assess depressive disorders. Determinants were studied using a multivariate proportional hazards model adjusted for antiretroviral treatment, sex, age, HIV risk factor, history of depression, hepatic disorder, alcohol abuse, and HIV-related or non-HIV-related events. RESULTS Thirty cases of depressive disorder (26 cases of depression and 4 suicide attempts) occurred during treatment in 27 patients (12 patients [7%] and 15 patients [8%] in the protease inhibitor-based and EFV-based treatment arms, respectively; P = .56). In the proportional hazards model, only age (hazard ratio, 1.6 per 10 years younger; 95% confidence interval, 1.0-2.6) and a history of depressive disorder (hazard ratio, 5.0; 95% confidence interval, 2.1-12.0) were associated with a risk of depressive disorders. The proportion of depressive patients (24%), as determined on the basis of the Center for Epidemiologic Studies-Depression Scale data, was stable during the follow-up period, without difference between treatment groups. Patients with a history of depressive disorder were more frequently depressed (53%) than were those without such history (22%; P = .03). CONCLUSIONS The frequency of depressive disorders was high in this population, but the disorders were not related to EFV treatment. Younger age and a history of depression are important determinants for depression and should be considered for early detection and case management.

Abstract
Objective To study the prognosis of HIV-infected patients with virological failure after exposure to three classes of antiretroviral drugs (ARVs). Design Cohort study. Setting: French Hospital Database on HIV. Patients Patients previously exposed to at least two nucleoside reverse transcriptase inhibitors (NRTIs), two protease inhibitors and one non-NRTI, with viral load (VL) values of >5000 copies/ml after the exposure criteria were met and a new treatment initiated between 1998 and 2001 with VL >5000 copies/ml. Main outcome measures Risk of new AIDS-defining-events (ADEs) or death from first introduction of a drug never used before occurring between 1998 and 2001 defined as baseline. Results The main baseline characteristics of the 1092 patients were: previous ADE in 49% of cases, median CD4 cell count 181 μl, median VL 4.9 log10 copies/ml, median duration of ARV therapy 5.0 years and previous exposure to a median of nine ARVs. The crude progression rates were 20.1/100 patient-years among patients included in 1998, 15.1 in 1999, 11.1 in 2000 and 8.6 in 2001. After adjustment for baseline characteristics, the calendar year of inclusion was associated with the risk of clinical progression ( P<0.001). When the types of newly available drugs used at baseline or during follow-up were introduced into the model, year of inclusion was no longer associated with the risk of clinical progression ( P=0.42), while exposure to amprenavir/r, lopinavir/r, abacavir or tenofovir was associated with a lower risk. Conclusions The clinical prognosis of heavily pretreated patients experiencing virological failure improved between 1998 and 2001, mainly thanks to the use of newly available drugs with more favourable resistance profiles.

Abstract
The influence of HAART on the survival of patients with AIDS-related lymphoma (ARL) was evaluated. A retrospective analysis of 73 HIV-1-infected patients with proven ARL diagnosed between 1992 and 2000 was conducted. Patients received uniformly the same chemotherapy regimen according to CD4 cell counts at NHL diagnosis:, patients with CD4 cells below or above 100 cells x 10(6)/liter received CHOP or ACVBP regimens, respectively. Event-free survival (EFS) and survival were estimated by the Kaplan-Meir method and a Cox model was used to evaluate the effect of different variables on survival. At diagnosis of ARL, the median age was 37 years and 22 patients (30%) had prior AIDS-defining events. Median CD4 cell count was 99 x 10(6)/liter. The median follow-up was 60 months. Ann Arbor stage 3-4 was noted in 60 patients (82%) and bone marrow or meningeal involvement was present in 13 (17%) and 12 (16%) patients, respectively. Two groups were identified: group 1 (n = 38) included patients who had never received HAART and group 2 (n = 35) included those who received HAART either before the diagnosis or following ARL. There was no statistical significant differences in lymphoma extensive stage, presence of B symptoms, meningeal involvement, CD4 cell count at diagnosis, prior AIDS events, or chemotherapy regimens between the two groups. Median survival (MS) of the whole cohort of patients was 8 months. Estimated EFS was significantly higher (30 months) in group 2 compared to group 1 (6.1 months) (p = 0.03). In the multivariate Cox model HAART has an independent significant effect on EFS (p = 0.0085). No influence on outcome was found for other variables except for prior AIDS and bone marrow involvement. HAART has significantly improved the survival and EFS in patients with ARL, independently of chemotherapy regimen.

Abstract
OBJECTIVE To study immunologic and clinical responses to HAART in patients over 50 years old. DESIGN AND METHODS A prospective cohort study which included 68 hospitals in France. A total of 3015 antiretroviral-naive patients, 401 of whom were aged 50 years or over, were enrolled following initiation of HAART. The influence of age on the mean CD4 cell count increase on HAART was studied by using a two-slope mixed model. Progression, defined by the occurrence of a new AIDS-defining event (ADE) or death, was studied by Cox multivariate analyses. RESULTS Among patients with baseline HIV RNA above 5 log copies/ml, CD4 mean increase during the first 6 months on HAART was +42.9 x 10(6) cells/l per month in patients under 50 years and +36.9 x 10(6) cells/l per month in patients over 50 years (P < 0.0001); subsequently, the respective monthly changes were +17.9 and +15.6 x 10(6) cells/l per month (P < 0.0001). Similar trends were observed in patients with baseline HIV RNA below 5 log copies/ml, and also after stratification for the baseline CD4 cell count. After a median follow-up of 31.5 months, 263 patients had a new ADE and 44 patients died. After adjustment for baseline characteristics, older patients had a significantly higher risk of clinical progression (hazard ratio (HR) = 1.52 [95% confidence interval (CI), 1.15-2.00]) and were more likely to achieve a viral load below 500 copies/ml [HR = 1.23, (95% CI, 1.11-1.38)]. CONCLUSION Patients over 50 years of age have an immunologic response to HAART. However, their CD4 cell reconstitution is significantly slower than in younger patients, despite a better virologic response. This impaired immunologic response may explain their higher risk of clinical progression.

Abstract
Stathmin, also referred to as Op18, is a ubiquitous cytosolic phosphoprotein, proposed to be a small regulatory protein and a relay integrating diverse intracellular signaling pathways involved in the control of cell proliferation, differentiation and activities. It interacts with several putative downstream target and/or partner proteins. One major action of stathmin is to interfere with microtubule dynamics, by inhibiting the formation of microtubules and/or favoring their depolymerization. Stathmin (S) interacts directly with soluble tubulin (T), which results in the formation of a T2S complex which sequesters free tubulin and therefore impedes microtubule formation. However, it has been also proposed that stathmin's action on microtubules might result from the direct promotion of catastrophes, which is still controversial. Phosphorylation of stathmin regulates its biological actions: it reduces its affinity for tubulin and hence its action on microtubule dynamics, which allows for example progression of cells through mitosis. Stathmin is also the generic element of a protein family including the neural proteins SCG10, SCLIP and RB3/RB3'/RB3". Interestingly, the stathmin-like domains of these proteins also possess a tubulin binding activity in vitro. In vivo, the transient expression of neural phosphoproteins of the stathmin family leads to their localization at Golgi membranes and, as previously described for stathmin and SCG10, to the depolymerization of interphasic microtubules. Altogether, the same mechanism for microtubule destabilization, that implies tubulin sequestration, is a common feature likely involved in the specific biological roles of each member of the stathmin family.

Abstract
OBJECTIVE To assess the impact of different patterns of adherence to highly active antiretroviral therapy (HAART), in particular, the relative impact of early and late adherence, on long-term immuno-virological response in HIV-infected individuals started on a protease inhibitor-containing regimen. DESIGN Clinical, immuno-virological and self-reported adherence data were collected at 4 (M4), 12 (M12), 20 (M20), 28 (M28) and 36 (M36) months after HAART initiation in the French APROCO cohort. METHODS A standardized self-administered questionnaire classified patients as non-adherent, moderately or highly adherent at each visit. Stable viral suppression at both M28 to M36, and a CD4 cell increase > 200 between M0 and M36 were used as outcome measures. RESULTS Of the 582 patients followed regularly through M36, 360 patients had complete adherence data. Although 59.2% were highly adherent at M4, only 25.8% maintained consistent high adherence throughout the follow-up. High adherence at M4 was independently associated with both stable viral suppression at M28-M36 [OR (95% CI): 2.8 (1.4-5.5)] and a CD4 cell increase > 200 during the same period [OR (95% CI): 3.9 (1.7-9.7)]. However, 'moderately adherent' patients between M12 and M36 had the same likelihood [OR (95% CI): 1.9 (1.1-3.2)] as patients who were always high adherent [OR (95% CI): 1.9 (1.1-3.2)] of achieving stable viral load suppression, relative to those who reported non-adherence episodes. CONCLUSION Optimizing adherence in the early months of treatment is crucial to ensure long-term immuno-virological high adherence during follow-up have a less negative impact. Priority should be given to interventions aimed to improve adherence in the early months of HAART.

Abstract
BACKGROUND Buprenorphine was approved in France for treating opiate dependence in July 1995 and can be prescribed by general practitioners (GPs). Most studies assessing buprenorphine maintenance treatment (BMT) outcomes have taken place in GP settings. An evaluation of BMT outcomes in patients already followed for their HIV-infection could supply additional information about the changes in addictive practices in a non-GP setting. METHODS We assessed BMT discontinuations and the course of self-reported addictive behaviours and characteristics associated with buprenorphine-injection misuse in 114 HIV-infected patients on BMT who were followed in a hospital-based outpatient department. RESULTS The continuous series of follow-up visits at which these 114 patients reported regular buprenorphine prescriptions accounted for 237.5 person-years of observation, i.e. 475 follow-up visits. Of the 114 patients on BMT, 43% continued BMT throughout the follow-up, 40% stopped it, and results for 17% were not available either because they did not answer the self-administered questionnaire (5%) or because they were lost to follow-up (12%). Addictive behaviours declined but buprenorphine injection misuse remained stable. Depression measured by the CESD score (RR=1.04 95%CI [1.01-1.06]), cocaine use (RR=2.48 95%CI [1.31-4.68]) and alcohol consumption exceeding 4 alcohol units (AU) per day (RR=2.29, 95%CI [1.17-4.46]) were independently associated with buprenorphine injection misuse among stabilised BMT patients. CONCLUSIONS Despite the reduction in drug injection after starting BMT, buprenorphine injection misuse mainly involves patients with characteristics of severe addiction. Better monitoring of the illicit drug use patterns of patients on BMT may suggest new medical strategies for GPs to improve BMT outcomes.

Abstract
The study, carried out in the French MANIF 2000 cohort of HIV positive patients contaminated through injecting drug use, assessed the impact of patients' sociodemographic and psychological characteristics, behaviors toward drug abuse, and antiretroviral treatment characteristics on the maintenance of adherence to HAART (highly active antiretroviral therapies). A total of 96 patients (30 men and 66 women), who were initially adherent at their first visit after HAART prescription, were considered for analysis. Among these 96 patients, 22 (22.9%) experienced adherence failure defined as a self-reported, non-adherence behavior at any visit before the 18th month of treatment. Logistic regression showed that lack of a stable relationship, active drug injection, and depression were independently associated with adherence failure. Patients' counseling for facilitating maintenance of adherence to HAART over time should focus on prevention of drug use, provision of social support and consider the potential impact of difficulties with treatment on psychological well-being.

Abstract
Stathmin family proteins interact with tubulin and negatively regulate its assembly in microtubules. One stathmin molecule forms a complex with two alphabeta tubulin heterodimers in an interaction that is weakened upon stathmin phosphorylation. The X-ray structure of crystals of the complex reveals a head-to-tail arrangement of the two tubulins which are connected by a long stathmin alpha helix. By holding tubulins in a curved complex that is not incorporated in microtubules, stathmin lowers the pool of "assembly competent" tubulin. An alternate mechanism has been also proposed to account for the stathmin action in vivo; it involves a direct interaction of stathmin with microtubule (+) ends. More experiments are needed to evaluate the relative contribution of this alternative mechanism to the regulation of tubulin assembly by stathmin.

Abstract
Objective To compare the efficacy and safety of a triple nucleoside combination to a protease inhibitor-containing triple regimen as first-line antiretroviral therapy (ART) in HIV-1-infected patients. Design Open-label study in HIV-1-infected ART-naive adults, randomized to receive either Combivir® (lamivudine 150 mg/zidovudine 300 mg twice daily) + abacavir (300 mg twice daily), or Combivir® + nelfinavir (750 mg every 8 h) for 48 weeks. Plasma HIV-1 RNA, CD4 cell count and adverse events were assessed at baseline and weeks 4, 8, 16, 24, 32, 40 and 48. Results 195 subjects (131 men, 64 women), median age 34 years, were randomized: 98 received combivir/abacavir and 97 combivir/nelfinavir. Baseline median plasma HIV-1 RNA was 4.2 log10 copies/ml [Interquartile range (IQR): 3.7-4.5.2] and 4.1 log10 copies/ml (IQR: 3.8–4.6), respectively. Baseline median CD4 cell count was 387 cells/mm3 (IQR: 194–501) and 449 cells/mm3 (IQR: 334–605), respectively. Nine patients (3 vs 6, respectively) did not start treatment or did not have any available efficacy data. At week 48, using the intent to treat analysis (switch/missing equals failure), plasma HIV-1 RNA was <50 copies/ml in 54/95 (57%) and 53/91 (58%) of subjects, respectively. Median CD4 increase was +110 and +120 cells/mm3, respectively. Possible hypersensitivity reactions to abacavir were reported in four subjects (4%). Conclusion The triple nucleoside combination combivir/abacavir is well tolerated as a first-line ART regimen in HIV-1-infected adults, with comparable antiviral activity to a nelfinavir-containing regimen at week 48.

Abstract
The fastest growing population of children in foster care today is quite young, and many of these children have significant health care needs. The General Accounting Office (GAO) reported that children in foster care "are among the most vulnerable individuals in the welfare population" (GAO, 1995, p. 1). Poverty, increased homelessness, substance abuse, and a rise in the incidence of persons with HIV all contribute to the problems faced by these children. The Caring Communities for Children in Foster Care Project, funded by the Maternal Child Health Bureau Integrated Services Medical Home Initiative with the American Academy of Pediatrics (AAP), investigated the availability of comprehensive health care services for children in foster care. The AAP recommends that pediatricians serve as the primary health care provider for children in foster care and also as consultants to child welfare agencies. Pediatric nurses play a crucial role in providing health care services to children in foster care. With an increased understanding of the potential physical and mental health care needs of children in foster care and the important role of foster parents, pediatric nurses can increase the likelihood of positive health outcomes for children in foster care.

Abstract
PURPOSE To describe the clinical features in HIV-1-infected patients treated with protease inhibitors (PIs) or not, and to determine factors related to occurrence of lipodystrophy (LD). METHOD We performed a cross-sectional analysis of 685 treated HIV-1-infected patients that were routinely followed in 6 Paris hospital centers between January and May 1999. Demographic data, familial and personal vascular risk factors, history of antiretroviral treatment, HIV plasma viral load, CD4 cell count, and metabolic data were collected. Clinical examination was based on an assessment of changes in abdominal, dorso-cervical, and breast girth and wasting of the limbs, face, and skin as quoted by the clinician. RESULTS The mean age at inclusion in the study was 38 years; 29.5% were women. At study assessment, 77.5% of patients were PI-treated and 22.5% had never received a PI. LD was observed in 403 (58.8%) patients, of whom 340 were currently receiving a PI and 63 had never received a PI. More than half of the lipodystrophic patients had a mixed form (53.9%), while 25.3% were classified as exclusive lipoatrophic and 20.8% as exclusive hypertrophic. In multivariate analysis, older age, duration of antiretroviral treatment (ART), antiretroviral combinations including stavudine, antiretroviral combinations including a PI, AIDS status, and a low HIV RNA were independently associated with occurrence of LD. CONCLUSION LD is frequently observed in PI-treated patients, but it is also observed in patients receiving an ART regimen without PIs. Our study suggests different underlying mechanisms, because immunovirological response to treatment as well as certain therapies were linked to the occurrence of LD. This hypothesis would be best clarified in a large prospective cohort of naive patients.

Abstract
Stathmin/Op18 destabilizes microtubules in vitro and regulates microtubule polymerization in vivo. Both a microtubule catastrophe-promoting activity and a tubulin sequestering activity were demonstrated for stathmin in vitro, and both could contribute to microtubule depolymerization in vivo. Stathmin activity can be turned down by extensive phosphorylation on its four phosphorylatable serines, and down-regulation of stathmin activity by phosphorylation is necessary for cells to proceed through mitosis. We show here that microinjection of a nonphosphorylatable Ser to Ala (4A) quadruple mutant in Xenopus two-cell stage embryos results in cell cleavage arrest in the injected blastomeres and aborted development, whereas injection of a pseudo-phosphorylated Ser to Glu quadruple mutant (4E) does not prevent normal development. Addition of these mutants to mitotic cytostatic factor-arrested extracts in which spindle assembly was induced led to a dramatic reduction of spindle size with 4A stathmin, and to a moderate increase with 4E stathmin, but both localized to spindle poles. Interestingly, the microtubule assembly-dependent phosphorylation of endogenous stathmin was abolished in the presence of 4A stathmin, but not of 4E stathmin. Altogether, this shows that the phosphorylation-mediated regulation of stathmin activity during the cell cycle is essential for early Xenopus embryonic development.

Abstract
Stathmin family phosphoproteins (stathmin, SCG10, SCLIP, and RB3/RB3'/RB3") are involved in signal transduction and regulation of microtubule dynamics. With the exception of stathmin, they are expressed exclusively in the nervous system, where they display different spatio-temporal and functional regulations and hence play at least partially distinct and possibly complementary roles in relation to the control of development, plasticity, and neuronal activities. At the molecular level, each possesses a specific "stathmin-like domain" and, with the exception of stathmin, various combinations of N-terminal extensions involved in their association with intracellular membrane compartments. We show here that each stathmin-like domain also displays specific biochemical and tubulin interaction properties. They are all able to sequester two alpha/beta tubulin heterodimers as revealed by their inhibitory action on tubulin polymerization and by gel filtration. However, they differ in the stabilities of the complexes formed as well as in their interaction kinetics with tubulin followed by surface plasmon resonance as follows: strong stability and slow kinetics for RB3; medium for SCG10, SCLIP, and stathmin; and weak stability and rapid kinetics for RB3'. These results suggest that the fine-tuning of their stathmin-like domains contributes to the specific functional roles of stathmin family proteins in the regulation of microtubule dynamics within the various cell types and subcellular compartments of the developing or mature nervous system.

Abstract
Death rates in the APROCO cohort of 1,157 HIV-1 infected adults starting for the first time a protease inhibitor-containing therapy were standardized to the 1996 French general population mortality rates stratified by age and gender. Median follow-up was 23 months and mortality rate was 2.2% person-years (95% confidence interval [CI] = 1.6-2.9). Overall mortality was 7.8 times higher than in the general population (95% CI = 5.7-10.4), 4.7 in men and 19.5 in women. Among the 144 patients considered complete responders, the death rate was 1.2% person-years (95% CI = 0.2-3.5) and mortality remained 5.1 times higher (95% CI = 1.0-14.9) than in the general population. Failure of treatment, long-term adverse effects, or less favorable socio-demographic status could explain these trends.

Abstract
Stathmin/Op 18 is a microtubule (MT) dynamics-regulating protein that has been shown to have both catastrophe-promoting and tubulin-sequestering activities. The level of stathmin/Op18 phosphorylation was proved both in vitro and in vivo to be important in modulating its MT-destabilizing activity. To understand the in vivo regulation of stathmin/Op18 activity, we investigated whether MT assembly itself could control phosphorylation of stathmin/Op18 and thus its MT-destabilizing activity. We found that MT nucleation by centrosomes from Xenopus sperm or somatic cells and MT assembly promoted by dimethyl sulfoxide or paclitaxel induced stathmin/Op18 hyperphosphorylation in Xenopus egg extracts, leading to new stathmin/Op18 isoforms phosphorylated on Ser 16. The MT-dependent phosphorylation of stathmin/Op18 took place in interphase extracts as well, and was also observed in somatic cells. We show that the MT-dependent phosphorylation of stathmin/Op18 on Ser 16 is mediated by an activity associated to the MTs, and that it is responsible for the stathmin/Op18 hyperphosphorylation reported to be induced by the addition of "mitotic chromatin." Our results suggest the existence of a positive feedback loop, which could represent a novel mechanism contributing to MT network control.

Abstract
We have identified a rapid protein phosphorylation event at residue serine 16 of stathmin using two-dimensional gel electrophoresis coupled to matrix-assisted laser desorption/ionization mass spectrometry in combination with post-source decay analysis, which is induced by the epidermal growth factor receptor. Phosphorylation is specifically mediated by the small GTPases Rac and Cdc42 and their common downstream target, the serine/threonine kinase p65PAK. Both GTPases have previously been shown to regulate the dynamics of actin polymerization. Because stathmin destabilizes microtubules, and this process is inhibited by phosphorylation at residue 16, Rac and Cdc42 can potentially regulate both F-actin and microtubule dynamics.

Abstract
Stathmin and SCG10 belong to a family of phosphoproteins associated to cell proliferation and differentiation. In the present study, we have analyzed immunocytochemically the distribution of these proteins during neurogenesis in the mouse olfactory system, from midgestation to adulthood. Data show that already at embryonic day 12, stathmin and SCG10 immunoreactivities were present in the olfactory and vomeronasal neurons, and their number increased greatly, colocalizing with neuronal specific tubulin, a marker of immature neurons. Later on up to adulthood, the distribution of stathmin and SCG10 became progressively restricted to a few immature receptor and chemosensory neurons. Significantly, in the olfactory epithelium, stathmin was seen in immature neurons and also in basal cells representing precursors of neuronal elements. Interestingly, before birth stathmin and SCG10 immunopositive cells were seen outside the olfactory epithelium, seemingly migrating toward the olfactory bulb. After regeneration in the adult following peripheral lesion of the olfactory epithelium, stathmin and SCG10 were again strongly expressed and generally colocalized with neuronal specific tubulin immunoreactivity. Overall these results indicate that stathmin and SCG10 are expressed in immature olfactory neurons as well as in the migrating cells generated from the olfactory epithelium, supporting the role of these proteins in neurogenesis and cell migration.

Abstract
Phosphoproteins of the stathmin family interact with the alphabeta tubulin heterodimer (tubulin) and hence interfere with microtubule dynamics. The structure of the complex of GDP-tubulin with the stathmin-like domain of the neural protein RB3 reveals a head-to-tail assembly of two tubulins with a 91-residue RB3 alpha helix in which each copy of an internal duplicated sequence interacts with a different tubulin. As a result of the relative orientations adopted by tubulins and by their alpha and beta subunits, the tubulin:RB3 complex forms a curved structure. The RB3 helix thus most likely prevents incorporation of tubulin into microtubules by holding it in an assembly with a curvature very similar to that of the depolymerization products of microtubules.

Abstract
We present here a first appraisal of the phosphorylation site specificity of KIS (for 'kinase interacting with stathmin'), a novel mammalian kinase that has the unique feature among kinases to possess an RNP type RNA-recognition motif (RRM). In vitro kinase assays using various standard substrates revealed that KIS has a narrow specificity, with myelin basic protein (MBP) and synapsin I being the best in vitro substrates among those tested. Mass spectrometry and peptide sequencing allowed us to identify serine 164 of MBP as the unique site phosphorylated by KIS. Phosphorylation of synthetic peptides indicated the importance of the proline residue at position +1. We also identified a tryptic peptide of synapsin I phosphorylated by KIS and containing a phosphorylatable Ser-Pro motif. Altogether, our results suggest that KIS preferentially phosphorylates proline directed residues but has a specificity different from that of MAP kinases and cdks.

Abstract
Stathmin is a cytosoluble phosphoprotein proposed to be a regulatory relay integrating diverse intracellular signaling pathway. Its interaction with tubulin modulates microtubule dynamics by destabilization of assembled microtubules or inhibition of their polymerization from free tubulin. The aim of this study was to probe the native structure of stathmin and to delineate its minimal region able to interact with tubulin. Limited proteolysis of stathmin revealed four structured domains within the native protein, corresponding to amino acid sequences 22-81 (I), 95-113 (II), 113-128 (III), and 128-149 (IV), which allows us to propose stathmin folding hypotheses. Furthermore, stathmin proteolytic fragments were mixed to interact with tubulin, and those that retained affinity for tubulin were isolated by size exclusion chromatography and identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The results indicate that, to interact with tubulin, a stathmin fragment must span a minimal core region from residues 42 to 126, which interestingly corresponds to the predicted alpha-helical "interaction region" of stathmin. In addition, an interacting stathmin fragment must include a short N- or C-terminal extension. The functional significance of these interaction constrains is further validated by tubulin polymerization inhibition assays with fragments designed on the basis of the tubulin binding results. The present results will help to optimize further stathmin structural studies and to develop molecular tools to target its interaction with tubulin.

Abstract
We recently discovered that stathmin was overexpressed in a subgroup of human breast carcinomas. Stathmin is a cytosolic phosphoprotein proposed to act as a relay integrating diverse cell signalling pathways, notably during the control of cell growth and differentiation. It may also be considered as one of the key regulators of cell division for its ability to destabilize microtubules in a phosphorylation-dependent manner. To assess the significance of stathmin overexpression in breast cancer, we evaluated the correlation of stathmin expression, quantified by reverse transcription polymerase chain reaction, with several disease parameters in a large series of human primary breast cancer (n = 133), obtained in strictly followed up women, whose clinico-pathological data were fully available. In agreement with our preliminary survey, stathmin was found overexpressed in a subgroup of tumours (22%). In addition, overexpression was correlated to the loss of steroid receptors (oestrogen, P = 0.0006; progesterone, P = 0.008), and to the Scarff-Bloom-Richardson histopathological grade III (P= 0.002), this latter being ascribable to the mitotic index component (P= 0.02). Furthermore studies at the DNA level indicated that stathmin is overexpressed irrespective of its genomic status. Our findings raise important questions concerning the causes and consequences of stathmin overexpression, and the reasons of its inability to counteract cell proliferation in the overexpression group.

Abstract
Anti-CV2 autoantibodies have recently been discovered in patients with paraneoplastic neurological diseases (PND). These disorders are associated with neuronal degeneration, mediated by autoimmune processes, in patients with systemic cancer. Anti-CV2 autoantibodies recognize a brain protein of 66 kDa developmentally regulated and specifically expressed by a subpopulation of oligodendrocytes in the adult brain. Here, we demonstrate that anti-CV2 sera recognize several post-translationally modified forms of Ulip4/CRMP3, a member of a protein family related to the axonal guidance and homologous to the Unc-33 gene product in Caenorhabditis elegans. The sequence of the human Ulip4/CRMP3 was determined and the gene localized to chromosome 10q25.2-q26, a region mutated in glioblastomas and containing tumour suppressor genes. The identification of the Ulip/CRMP proteins as recognized by anti-CV2 sera should provide new insights into the role of Ulip/CRMPs in oligodendrocytes and into pathophysiology of PND.

Abstract
In the present work, we investigated the expression of cadherin mRNAs in the adult neuromuscular system either under normal conditions or following experimental neurotomy. Cadherin-6, a marker of Schwann cell precursors, was not expressed in the adult peripheral nerve, while M-cadherin, cadherin-11, and N-cadherin were expressed both by glial and conjunctive cells. Moreover, the three transcripts were transiently upregulated in the distal stump of neurotomized sciatic nerve during Wallerian degeneration: N-cadherin was abundant in myelinating Schwann cells during myelin degradation, while M-cadherin and cadherin-11 may be upregulated in proliferating Schwann cells. M-cadherin, cadherin-11, and N-cadherin were also detected in myofibres and endomysium of adult gastrocnemius muscle. Following neurotomy, cadherin-11 was only transiently increased in denervated myofibres, while M-cadherin was increased and sustained for at least 21 days postoperation. In contrast, N-cadherin was not upregulated in denervated myofibres. Thus, we defined here a combination of cadherins expressed in the adult nerve and muscle, and modulated during Wallerian degeneration and muscle denervation. The comparison of the expression pattern of this combination of cadherins to the one previously described during embryonic development shows that chronically denervated Schwann and muscle cells do not reverse to embryonic state (recapitulative hypothesis), but present specific phenotypic features.

Abstract
In order to determine the prevalence of HIV infection in french patients with end-stage renal disease (ESRD) on maintenance dialysis therapy, questionnaire forms were mailed out in february 1997 to the heads of the 260 dialysis facilities. We documented number of patients on maintenance dialysis therapy (hemo and peritoneal dialysis) and for HIV infected dialysis patients: age, gender, cause and duration of ESRD, known duration of HIV infection, risk factors for HIV infection, HBV and/or HCV infection, presence of clinical acquired immunodeficiency syndrome (AIDS), total CD4 count and treatment with antiretroviral agents. Questionnaire forms were returned from 98% of the dialysis facilities. As of february 1997 some 22,707 patients with ESRD were treated by renal replacement therapy, 19,947 by hemodialysis (HD) and 2760 by peritoneal dialysis (PD). 82 patients with ESRD and HIV infection were reported corresponding to 0.36% prevalence rate of all patients undergoing dialysis at the time specified. The 82 study subjects with ESRD and HIV infection received hemodialysis (79 patients) or peritoneal dialysis (3 patients) in 42 facilities. Forty seven patients were treated in Paris and suburbs and 9 in our own center. All 82 patients comprised 63% men and 47% women which included patients coming from Africa (37%), Caribbean and Oceania (28%), Europe (35%) of a mean age of 41.8 years. Modes of transmission were homobisexuals 15%, heterosexuals 31%, intravenous drug abusers 17%, blood transfusion 17% and unknown 20%. The mean duration of HIV infection was 96 months (range 12-168 months) and the mean duration of ESRD was 58 months (range 1-235 months). HIV associated nephropathy was established in 31%. AIDS was diagnosed in 25 patients. Seventy one percent of the patients were receiving an antiretroviral drug (tritherapy in 25% of cases). In conclusion HIV prevalence rate among French dialysis patients is low and focused in Paris and oversea. Sexual transmission is the most important HIV contamination but blood transfusion transmission remains greater than in general HIV population. Survival has improved compared with the survival rate reported in the 1980s.

Abstract
Stathmin is a 19 kDa cytosolic phosphoprotein, proposed to act as a relay integrating diverse intracellular signaling pathways involved in regulation of cell proliferation, differentiation, and function. To gain further information about its significance during early development, we analyzed stathmin expression and subcellular localization in mouse oocytes and preimplantation embryos. RT-PCR analysis revealed a low expression of stathmin mRNA in unfertilized oocytes and a higher expression at the blastocyst stage. A fine cytoplasmic punctuate fluorescent immunoreactive stathmin pattern was detected in the oocyte, while it evolved toward an increasingly speckled pattern in the two-cell and later four- to eight-cell embryo, with even larger speckles at the morula stage. In blastocysts, stathmin immunoreactivity was fine and intense in inner cell mass cells, whereas it was low and variable in trophectodermal cells. Electron microscopic analysis allowed visualization with more detail of two types of stathmin immunolocalization: small clusters in the cytoplasm of oocytes and blastocyst cells, together with loosely arranged clusters around the outer membrane of cytoplasmic vesicles, corresponding to the immunofluorescent speckles in embryos until the morula stage. In conclusion, it appears from our results that maternal stathmin is accumulated in the oocyte and is relocalized within the oocyte and early preimplantation embryonic cell cytoplasm to interact with specific cytoplasmic membrane formations. Probably newly synthesized, embryonic stathmin is expressed in the blastocyst, where it is localized more uniformly in the cytoplasm mostly of inner cell mass (ICM) cells. These expression and localization patterns are probably related to the particular roles of stathmin at the successive steps of oocyte maturation and early embryonic development. They further support the proposed physiologic importance of stathmin in essential biologic regulation.
