Abstract
Arboviruses are viral diseases transmitted by mosquitoes and tics bites. They are a major cause of morbidity and sometimes mortality. Their expansion is constant and due in part to climate change and globalization. Mostly found in tropical regions, arboviruses are sometimes the source of epidemics in Europe. Recently, the Chikungunya virus and the Zika virus were responsible for very large epidemics impacting populations that had never been in contact with those viruses. There are currently no effective antiviral treatments or vaccines. Ocular manifestations due to those infections are thus more frequent and increasingly better described. They are sometimes, as with Zika, complicated by a congenital ocular syndrome. The goal of this review is to describe the ophthalmological manifestations of Dengue fever, Chikungunya virus, Zika virus, West Nile virus, and yellow fever.

Abstract
OBJECTIVES Direct-Acting Antivirals (DAAs) opened a new era in HCV treatment. We report the impact of HCV treatment in French HIV-HCV coinfected patients. METHODS All HIV-HCV patients from the Dat'AIDS cohort followed between 2012 and 2015 were included. HCV status was defined yearly as naive, spontaneous cure, sustained virological response (SVR12), failure or reinfection. RESULTS Among 32,945 HIV-infected patients, 15.2% were positive for anti-HCV antibodies. From 2012 to 2015, HCV incidence rate increased from 0.35%PY to 0.69%PY in MSM, while median incidence was 0.08%PY in other patients. Median reinfection rate was 2.56%PY in MSM and 0.22%PY in other patients. HCV treatment initiation rate rose from 8.2% in 2012 to 29.6% (48.0% in pre-treated patients vs 22.6% in naïve patients). SVR12 rate increased from 68.7% to 95.2%. By the end of 2015, 62.7% of the patients were cured either spontaneously or following SVR. CONCLUSIONS HCV treatment dramatically increased in HIV-HCV patients in France from 2012 to 2015 resulting in HCV cure in nearly two-thirds of the patients in this cohort. Combined with a declining HCV prevalence, the prevalence of active HCV infection among HIV patients will drastically decrease in the forthcoming years.

Abstract
Treatments for hematological malignancies have improved considerably over the past decade, but the growing therapeutic arsenal has not benefited adult T-cell leukemia (ATL) patients. Oncolytic viruses such as vesicular stomatitis virus (VSV) have recently emerged as a potential treatment of solid tumors and leukemias in vitro and in vivo. In the current study, we investigated the ability of VSV to lyse primary human T-lymphotropic virus type 1 (HTLV-1)-infected T-lymphocytes from patients with ATL. Ex vivo primary ATL cells were permissive for VSV and underwent rapid oncolysis in a time-dependent manner. Importantly, VSV infection showed neither viral replication nor oncolysis in HTLV-1-infected, nonleukemic cells from patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), and in naive CD4(+) T-lymphocytes from normal individuals or in ex vivo cell samples from patients with chronic lymphocytic leukemia (CLL). Interestingly, activation of primary CD4(+) T-lymphocytes with anti-CD3/CD28 monoclonal antibody, and specifically with anti-CD3, was sufficient to induce limited viral replication and oncolysis. However, at a similar level of T-cell activation, VSV replication was increased fourfold in ATL cells compared to activated CD4(+) T-lymphocytes, emphasizing the concept that VSV targets genetic defects unique to tumor cells to facilitate its replication. In conclusion, our findings provide the first essential information for the development of a VSV-based treatment for ATL.

Abstract
Using TPHA instead of VDRL for syphilis blood-screening since 1995 showed an important increase of positive blood donors in Martinique. Yaws, another treponema disease, has been present on the island until 1975-1980. Usual tests are unable to identify which type--venereal or non venereal--of treponema is involved. Our study, carried out from January 1995 to May 1999, compares actual serological and epidemiological characteristics of TPHA reactive donors to former studies. In our results, the frequency of reactive TPHA is about 1.04% in blood donations. Donors are carrying serological tracks of a past treponema disease with very low rate of antibodies, sometimes linked to yaws. Among donors aged 18 to 30, prevalence is low and is going to become similar to the rate observed in Continental France. This means that this problem will disappear in new donor generations. We suggest the possibility for them to continue blood donation, if their personal preliminary enquiry fits the admission criteria for blood giving.

Abstract
Several reports suggest that HTLV-I/HIV coinfection may be associated with an increased risk of HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). In HTLV-I-monoinfected patients, the occurrence of HAM/TSP is associated with high peripheral blood HTLV-I proviral load. Using a real-time quantitative PCR assay, we assessed the proviral DNA load in peripheral blood mononuclear cells (PBMCs) from 15 asymptomatic HTLV-I-monoinfected patients, 15 HTLV-I-monoinfected patients with HAM/TSP, and 25 HTLV-I/HIV-1 coinfected patients, including 4 with HAM/TSP. We also measured HIV-1 proviral DNA load in PBMCs from the coinfected patients. The median HTLV-I proviral loads were 6,800 and 4,100 copies per 10(6) PBMCs in the asymptomatic monoinfected and coinfected groups, and 58,800 and 43,300 copies per 10(6) PBMCs in the monoinfected and coinfected patients with HAM/TSP, respectively. The difference between HTLV-I proviral loads in HAM/TSP and asymptomatic monoinfected patients was statistically significant (p < 0.0001), but there was no difference between the HTLV-I-monoinfected and HTLV-I/HIV-1-coinfected groups. There was no correlation between HTLV-I and HIV-1 proviral load. HTLV-I proviral load did not correlate with the CD4+ T lymphocyte count. Among patients with no HTLV-I disease, the median copy number of HTLV-I per 10(6) circulating CD4+ T cells was 114,000 in the coinfected group and 16,700 in the monoinfected group, but the difference was not significant (p = 0.089). These data do not confirm the hypothesis in which HIV-1 coinfection would increase HTLV-I proviral burden in the PBMCs. However, depletion of the CD4+ T cell subset, the main target of HTLV-I, could be counterbalanced by an up-regulation of HTLV-I replication or by greater resistance of HTLV-I-infected cells to HIV-1-induced destruction.

Abstract
BACKGROUND AND OBJECTIVES Posttransfusion hepatitis still occurs at an incidence of about 1 in 118,000 for HBV and 1 in 220,000 for HCV. This collaborative study aimed to determine the prevalence of a novel flavivirus, GBV-C/HGV, even though its role in transfusion-associated hepatitis is uncertain. MATERIALS AND METHODS GBV-C/HGV RNA was detected by PCR using either the Boehringer detection kit or by primers previously described. HGV antibodies were detected by a serological assay from Boehringer. RESULTS The observed GBV-C/HGV RNA frequency was 3.4%. HGV antibodies occurred in 9.5% of donors. CONCLUSION In our study, 12. 9% of the donors had been in contact with the GBV-C/HGV virus.

Abstract
The human retrovirus HTLV-I is responsible for the chronic progressive myelopathy, TSP/HAM, characterized by the presence of infiltrated T lymphocytes, cytokines, and matrix metalloproteinases (MMPs) within spinal cord lesions. MMPs have been associated with several neurological diseases, and we previously reported the specific presence of the extracellular matrix-degrading protease, MMP-9, in the cerebrospinal fluid of TSP/HAM patients. Nevertheless, previous studies have not yet shown whether the expression of MMP-9 is associated with HTLV-I infection per se, or with neurological symptoms following infection. In the present work, the presence of tissue inhibitors of metalloproteinases 1 and 3 (TIMP-1 and TIMP-3) and of MMP-9 in the CSF of HTLV-I-infected individuals was compared in TSP/HAM patients versus HTLV-I carriers without neurological symptoms. TIMP-3, a regulator of MMP activity and cell survival, was detected with a significantly higher frequency in the TSP/HAM group and paralleled the increased levels of MMP-9 and neopterin, a sensitive indicator of cellular immune activation. These data may reflect the intense cell remodeling that occurs intrathecally in inflamed tissue. Changes in MMP, TIMP, and neopterin expression were not related to age at onset of disease, grade of motor disability, progressor status, or duration of disease, presumably indicating that TSP/HAM patients are continuously subjected to viral and immunological pressure. All these observations suggest that TIMPs and MMPs may contribute to the pathogenesis of TSP/HAM, and hence a new therapeutic strategy targeting the MMP/TIMP balance is needed. These observations also suggest that MMP-9 and TIMP-3 in CSF may be useful markers in the follow-up of the efficacy of therapeutic trials in TSP/HAM patients.

Abstract
BACKGROUND The diagnosis of primary HIV infection is a crucial element in the fight against the AIDS epidemic. Clinical manifestations associated with primary infection are nonspecific. Dengue is a possible differential diagnosis. CASE REPORT A 15-year-old adolescent living in Martinique consulted for a syndrome suggestive of infectious mononucleosis. The annual dengue epidemic was at its acme at this time. Serum was positive for IgM and the diagnosis of dengue was retained. The diagnosis of recent HIV infection was made two months later (unprotected homosexual intercourse two weeks before onset of clinical signs). Retrospective analysis of the earlier samples at the time of the viral syndrome demonstrated that the patient actually had an acute retroviral syndrome. DISCUSSION The clinical and biological manifestations of dengue and primary HIV infection are nonspecific and similar to those of infectious mononucleosis. Potential exposure to HIV and recent presence in endemic dengue regions (tropical areas in America, Asia and Africa) can provide helpful guidance for differential diagnosis.

Abstract
We report on the frequency of genetic mutations associated with drug resistance in antiretroviral treatment-naive patients from Martinique (French West Indies), where zidovudine (ZDV) has been available since 1987 and where combination therapy developed simultaneously with its use in continental France. Genotypic resistance was studied in plasma HIV RNA from samples collected between 1988 and 1998 from 70 antiretroviral-naive study subjects, half presenting with either primary infection or documented seroconversion. A line probe assay (LIPA) was used to detect substitutions on the reverse transcriptase (RT) codons 41, 69, 70, 74, 184, and 215. Direct sequencing was used to complete the data for RT codons which were uninterpretable by LIPA. Of these patients, 17 harbored mutated viruses with one or more mutations in the RT gene codons analyzed. ZDV resistance mutations T215Y/F, M41L, and K70R were found in 2, 5, and 12 individuals, respectively. Mutant strains L74V (didanosine [ddI] and dideoxycytidine [ddC]) were detected in 3 patients and M184V (lamivudine/ddI/ddC) in 4 patients. However, pure mutant results at one or more codons of interest were observed in only 5 (7%; 95% confidence interval [CI], 1%-13%) patients, all involving ZDV resistance. One carried both mutations T215Y and M41L known to confer a high degree of phenotypic resistance to ZDV. Among a subgroup of 28 patients with a timepoint of infection after 1995, 24 [86%; approximately 95% CI, 73%-99%) presented with a wild-type pattern. The significance of the high prevalence of mixed patterns observed in drug-naive patients remains unclear. However, the frequency of primary mutant genotypes associated with high levels of drug resistance is low in Martinique and in this study we did not observe any currently increased tendency in this frequency.

Abstract
There have been several reports of vaso-occlusive events and sudden death in subjects with sickle cell trait. However, the precise mechanism underlying these episodes remains unclear. The clinical observations have been supported by in vitro studies in which haemoglobin AS (Hb AS) red cells showed abnormalities of their filterability, probably related to gelling or polymerisation of the Hb AS. These in vitro studies and reports in the literature of sickle-cell hearts led the authors to investigate the possible association between AS subject and coronary risk. The results of coronary angiography in 9 patients with Hb AS, paired with respect to the usual cardiovascular risk factors, were compared with those of 18 AA subjects. The number of patients who underwent coronary bypass surgery for three-vessel disease was much greater in the AS subjects. However, the difference was not statistically significant. This tendency of AS subjects to develop thrombosis and coronary artery disease requires further study with larger numbers of patients.

Abstract
GB virus C/hepatitis G virus (GBV-C/HGV) RNA was detected by reverse transcription-polymer- ase chain reaction with primers derived from the nonstructural region 3 (NS3) in 9 (4.1%) of 221 blood donors and 2 of 20 (10%) hemophilia patients in Martinique, French West Indies. Anti-E2 antibodies were found in sera from 33 (14.9%) of the blood donors and 5 (25%) of the hemophiliacs. None of the subjects was positive for both GBV-C/HGV RNA and anti-E2. Among the 20 hemophiliacs, 12 (60%) had anti-HCV antibodies and 7 (35%) were positive for HCV RNA by PCR. All patients positive for HCV markers belonged to the group of 13 patients exposed previously to blood factor concentrates that were not activated virally. Nucleotide sequences of the 5'-untranslated region (5'UTR) of the GBV-C/HGV genome were obtained for the 10 NS3 PCR positive samples. Phylogenetic comparison of these isolates with reference isolates published previously showed a strong homology with European and American GBV-C/HGV strains, 8 isolates belonging to the genotype 2a and 1 isolate to the type 2b. The isolate from 1 blood donor was identified as subtype 1a, indicating the presence of West African type strains.

Abstract
BACKGROUND Screening for human T-lymphotropic virus type I (HTLV-I) antibodies in volunteer blood donors has been systematic in the French West Indies since 1989. Western blot-indeterminate results are commonly obtained. The significance of these indeterminate serologic patterns in HTLV-I-endemic areas is still unclear. STUDY DESIGN AND METHODS During a 2-year period, 9759 blood donors were tested for HTLV-I antibodies. The epidemiologic features of HTLV-I-seropositive, -seroindeterminate, and -seronegative donors were compared. A lookback investigation was performed for the HTLV-I-seropositive donors, and the HTLV-I-seroindeterminate individuals were followed up. RESULTS Thirty-nine donors (0.4%) were HTLV-I seropositive and 49 (0.5%) were seroindeterminate. The age and sex ratio characteristics of the seroindeterminate donors are divergent from those of the HTLV-I-seropositive group and are more like those of the seronegative population. However, during the study period, three cases of seroconversion after an initial seroindeterminate profile were reported. Two cases were detected through follow-up of 38 HTLV-I-seroindeterminate donors over a mean of 8 months (2-24 months). The third seroconverter belonged to the HTLV-I-seropositive group and was identified through lookback investigation. This case is atypical, with p19 reactivity for several months before HTLV-I seropositivity. CONCLUSION These findings indicate that, although HTLV-I-seroindeterminate donors mainly are HTLV-I-noninfected, the rate of seroconversion in a repeat blood donor population from an endemic region must be taken into consideration. Moreover, the case of delayed seroconversion observed in this study suggests the difficulty of counseling seroindeterminate blood donors in endemic regions.

Abstract
We have compared the storage quality of three groups of 10 red blood cell concentrates of the AA, AS and AC haemoglobin phenotype. The 30 samples were drawn on CPD on day 0, and were centrifuged 6 hours later. Leukocytes were removed on D1 and the samples were kept at +4 degrees C for 42 days in SAG-mannitol. Viability tests were performed using a series of in vitro tests, including: ATP, 2,3-DPG, K+, glucose, lactic acid, pH, osmotic fragility tests and erythrocytic morphology determination. Results demonstrated a good functional quality for AS and AC haemoglobin RBCs. Higher 2,3-DPG levels were found in Hb AS and Hb AC. A lower osmotic fragility in Hb AC and AS RBCs versus Hb AA was observed; no significant difference was found in terms of ATP levels and other parameters. In addition no variation in S and C haemoglobin levels and no sickling were observed. In conclusion, these results indicate an overall good quality for haemoglobin AS and AC RBCs. Further in vivo studies must now be performed in order to confirm the transfusional quality of haemoglobin AS and AC RBCs.

Abstract
The tetrapeptide acetyl-N-Ser-Asp-Lys-Pro (AcSDKP) inhibits the entry into DNA synthesis of murine spleen colony-forming units (CFU-S) and protects these cells during chemotherapy. This synthetic peptide also inhibits the growth of normal human marrow progenitors granulocyte-macrophage colony-forming units (CFU-GM) and erythroid burst-forming units (BFU-E) and decreases their percentage in DNA synthesis at nanomolar concentration. In view of its clinical application as a marrow protector, we have investigated its effects on malignant cells. Studies were carried out on HL-60 cells and on fresh leukemic cells from patients with either chronic myeloid leukemia (CML) or acute myeloid leukemia (AML). Results showed that AcSDKP, whatever the doses used, did not modify the proliferation of both HL-60 cells and AML cells even when enhanced by stimulating factors such as interleukin 3 or granulocyte-macrophage colony-stimulating factor (GM-CSF). In addition, no change in the number and the percentage in S-phase of both HL-60 clonogenic cells and CML progenitors was observed. Our data clearly demonstrate that the tetrapeptide AcSDKP was ineffective on leukemic cells and therefore by acting selectively on normal progenitors represents a potent therapeutical agent for the protection of normal bone marrow progenitors during chemotherapy.
