Risk factors for hepatitis C transmission in HIV patients, Hepacam study, ANRS 12267 Cambodia.

In 2009, we conducted a case-control study to explore the routes of HCV transmission in people living with HIV/AIDS (PLHIV) in Cambodia. Cases were HCV/HIV co-infected patients (who tested RT-PCR positive for HCV-RNA or had confirmed presence of HCV antibodies) (n = 44). Controls were HIV mono-infected patients, with no HCV antibodies (n = 160). They were recruited among the PLHIV presenting at one national reference centre of HIV/AIDS. Multivariate analysis showed that factors associated with the co-infection were the age older than 50 years (OR 5.4, 95 % confidence interval (CI) 1.5-19.6), the exposure to multiple parenteral infusions before the year 2000 (OR 3.4, 95 % CI 1.5-7.6), to surgery (OR 2.6, 95 % CI 1.2-5.7) and to fibroscopy (OR 2.4, 95 % CI 1.0-5.7). These results show the need to implement HCV screening in PLHIV, to support the implementation of national infection control guidelines, and to reinforce public awareness on the risks linked to parenteral medications.

Psychiatric Symptoms and Cognitive Disorders in Behçet's Disease: A Single-Center, Cross-Sectional Study.

BACKGROUND: Behçet's disease (BD) is a rare form of vasculitis involving both veins and arteries of all calibers. Psychological symptoms and cognitive impairment appear to be frequent, but few data are available. METHODS: All consecutive patients in our center fulfilling the 2013 BD criteria underwent a psychometric evaluation with auto- (SCL-90-R and Modified Fatigue Index) and hetero-questionnaires (MINI). A standardized test battery assessed cognitive dysfunction. Data were correlated with BD activity as well as quality of life (SF-36). RESULTS: We included 20 consecutive patients (16 men, four women) with a median [IQR] age of 38 (30.0-45.5) and a median disease duration of 7 years (1.8-11.0). Five patients had an abnormal brain MRI. The SCL-90-R questionnaire highlighted eight psychopathological profiles (42.1%) that correlated with altered quality of life and more severe fatigue. The most frequent symptoms were anxiety (9/19, 47.4%), somatization (8/19, 42.1%) and phobia (5/19, 26.3%). Psychopathological symptoms appeared to be more severe, but not more frequent, in neuro-Behçet's patients. Based on standardized cognitive evaluation, nine patients had cognitive impairment defined by three or more altered tests. Notably, 6/9 patients did not have any complaint of memory loss and were thus considered ansognostic. CONCLUSION: Cognitive involvement was significantly associated with BD activity score (BSAS) but not with brain MRI abnormalities.

18F-FDG PET/CT and MRI in Necrotizing Autoimmune Myopathy: "The Scarface Sign".

Necrotizing autoimmune myopathy (NAM) is a relatively newly recognized subgroup of idiopathic inflammatory myopathies. The common histopathologic features are myocyte necrosis without significant inflammation. Necrotizing autoimmune myopathy can be associated with connective tissue disorders but can also be triggered by viral infections such as human immunodeficiency virus or malignancy, be statin-induced NAM, or be idiopathic. Here, the authors present the case of a 58-year-old man who was referred to our PET unit for a suspected paraneoplastic syndrome in a context of NAM. Complementary contrast-enhanced CT and 3-dimensional T1-weighted MRI were carried out subsequently in order to resolve the PET/CT abnormalities.

Intra-venous bevacizumab in hereditary hemorrhagic telangiectasia (HHT): A retrospective study of 46 patients.

BACKGROUND: Bevacizumab, an anti-VEGF monoclonal antibody, has recently emerged as a new option for severe forms of hereditary hemorrhagic telangiectasia (HHT). Its utilization in this orphan disease has rapidly spread despite the lack of randomized trials and international guidelines. The objective of this study is to report the main clinical data (baseline characteristics, dose schedule, efficacy, adverse events and deaths) of HHT patients treated by intravenous bevacizumab in France. METHODS: Retrospective observational study of HHT patients treated with bevacizumab for a severe form of the disease in the 14 centers of the French HHT network. RESULTS: Forty-six patients (median age: 68 years) were treated between March 2009 and May 2015. Ten patients were treated for high output cardiac failure, 20 patients for severe hemorrhages and 16 for both indications. The standard protocol (6 infusions of 5mg/kg every 2 weeks) was initially used in 89% of the cases but diverse strategies were subsequently applied. A clinical improvement was noted by the referent physician for 74% of the patients with a median effect's duration of 6 months. Wound healing complications led to 2 amputations. Arthralgia/arthritis and arterial hypertension occurred in 5 patients each. One third of the patients were dead at the time of the final update, coherently with age and the poor prognosis of these highly symptomatic patients. CONCLUSION: Intravenous bevacizumab seems to provide a clinical benefice in severe HHT patients. Precautions concerning wound healing and vascular pathologies must be respected. Prospective double blinded versus placebo trials are needed.

Epstein-Barr virus viral load in human immunodeficiency virus-positive patients with reactive hemophagocytic syndrome.

Because human immunodeficiency virus (HIV)-infected patients control Epstein-Barr virus (EBV) replication poorly, we hypothesized that reactive hemophagocytic syndrome (HS) in these patients may be associated with poor control of EBV. The files of 314 patients with a suspected diagnosis of HS were retrospectively reviewed. EBV viral load at the time of HS was compared between HIV-positive and -negative patients. A confirmed diagnosis of HS was made in 162 patients [109 males, median age 48 (35-62) years]. Among them, 61 (38%) were HIV positive [median HIV viral load 3.2 (1.6-5.5) log/ml, median CD4 count 94 (28-190)/mm(3)]. The median EBV viral load was significantly higher in HIV-positive than in HIV-negative patients [4.0 (2.9-4.6) vs 2.5 (0-4.2) log/ml, p = 0.002]. It was higher both in patients with hematological malignancy-associated HS [4.0 (2.9-4.4) vs 2.9 (0-4.9) log/ml, p = 0.03] and in patients with infection-associated HS [3.9 (0-4.9) vs 0 (0-4.1) log/ml, p = 0.14]. However, EBV viral load was not significantly higher in HIV-infected patients with confirmed HS than in HIV-infected patients for whom HS was unlikely [4.0 (2.9-4.6) vs 3.9 (2.6-4.1) log/ml, p = 0.48].The high EBV viral load observed in HIV-infected patients with HS may be more likely to reflect the chronic HIV infection than to be the direct trigger of HS.

Immunologic and Virologic Progression in HIV Controllers: The Role of Viral "Blips" and Immune Activation in the ANRS CO21 CODEX Study.

Some HIV controllers (HICs) experience CD4+T cell count loss and/or lose their ability to control HIV. In this study, we investigated the rate of immunologic and/or virologic progression (ImmP/VirP) and its determinants in the ANRS CO21/CODEX cohort. Immunologic progression was defined as a lasting fall in CD4+T cell count below 350/mm(3) or more than 200/mm(3) with a baseline count below 600/mm(3). Virologic progression was defined as a HIV viral load (VL) above 2000 copies/mL on two consecutive determinations. Clinical characteristics, immune activation, ultrasensitive HIV VL and total HIV DNA were analyzed. Disease progression was observed in 15 of the 217 patients followed up between 2009 and 2013 (ImmP, n = 10; VirP, n = 5). Progressors had higher ultrasensitive HIV RNA levels at inclusion (i.e. 1-2 years before progression) than non-progressors. ImmP had also lower CD4+T cell nadir and CD4+T cell count at inclusion, and VirP had higher HIV DNA levels in blood. T cell activation and IP10 levels at inclusion were significantly higher in ImmP than in non-progressors. In summary, the lasting loss of CD4+T cells, residual HIV replication and basal levels of immune activation appear to be major determinants of progression in HICs. These factors should be considered for adjusting their follow-up.

Mucor irregularis-associated cutaneous mucormycosis: Case report and review.

Solid organ transplant recipients are at risk for invasive fungal diseases, and are also exposed to healthcare-associated mucormycosis. Mainly causing localized cutaneous mucormycosis, Mucor irregularis infection is reported for the first time in a kidney-transplant recipient. A healthcare-associated origin was highly suspected in this case. We performed a literature review and highlight the characteristics of this very rare fungus.

High efficacy of lopinavir/r-based second-line antiretroviral treatment after 24 months of follow up at ESTHER/Calmette Hospital in Phnom Penh, Cambodia.

BACKGROUND: The number of patients on second-line highly active antiretroviral therapy (HAART) regimens is increasing in resource-limited settings. We describe the outcomes after 24 months for patients on LPV/r-based second-line regimens followed up by the ESTHER programme in Phnom Penh, Cambodia. METHODS: Seventy patients who initiated second-line HAART regimens more than 24 months earlier were included, and immuno-virological data analyzed. HIV RNA viral load was determined by real-time RT-PCR. HIV-1 drug resistance was interpreted according to the ANRS algorithm. RESULTS: Of the 70 patients, two were lost to follow up, three died and 65 (92.8%) remained on second-line treatment after 24 months of follow up (median duration of treatment: 27.4 months). At switch to second-line, the median CD4 T cell count was 106 cells/mm³ and the median viral load was 4.7 Log10. Second-line regimens prescribed were ddI/3TC/LPV/r (65.7%), ddI/TDF/LPV/r (10.0%), ddI/AZT/LPV/r (8.6%) and TDF/3TC/LPV/r (7.1%). The median CD4 T cell gain was +258 cells/mm³ at 24 months (n = 63). After 24 months of follow up, 92.3% (60/65) of the patients presented undetectable viral loads, giving an overall treatment success rate of 85.7% (CI: 75.6- 92.0) in intent-to-treat analysis. CONCLUSIONS: These data suggest that a LPV/r-based second-line regimen is associated with a high rate of virological suppression and immune reconstitution after 24 months of follow up in Cambodia.

Prolonged valproic acid treatment does not reduce the size of latent HIV reservoir.

OBJECTIVE: To investigate the impact of prolonged valproic acid treatment on the HIV reservoir in patients on highly active antiretroviral therapy. DESIGN: In a single-center pilot study, the size of the HIV reservoir of 11 patients receiving valproic acid for seizures for more than 2 years was compared with 13 matched patients. In addition, the outcome of patients receiving valproic acid in the French clinical trials of scheduled treatment interruption was recorded. METHODS: Total and integrated HIV-1 DNA in, respectively, peripheral blood mononuclear cells and CD4 T cells of the patients were quantified by real-time PCR methods. The frequency of CD4 T cells carrying replication-competent virus was estimated by a quantitative limiting-dilution assay in which virus growth was detected by RT-PCR in culture supernatants of activated CD4 T cells. Clinical charts of the patients included in scheduled treatment interruption trials receiving valproic acid were reviewed. RESULTS: Total and integrated HIV DNA were logarithmically more abundant than cells carrying replication-competent virus, but there was no significant difference in these three parameters between the two groups of matched patients. Three patients receiving valproic acid were included in scheduled treatment interruption trials. The rebound of viral replication was similar to that of the other patients of the trials. CONCLUSION: Long-term valproic acid therapy seems to be insufficient to reduce the size of the HIV-1 reservoir.
