Objectives: The aims of the study were to assess in patients with advanced HIV disease receiving antiretroviral therapy (ART) intensification with enfuvirtide (i) resistance at virological failure (VF), (ii) impact of baseline tropism on immunovirological response, and (iii) HIV-1 DNA tropism evolution during ART. Methods: The ANRS 130 APOLLO randomized trial evaluated in naive patients the immunovirological impact of standard ART without (control arm) or with enfuvirtide. Tropism was determined on RNA and DNA by V3-loop sequencing interpreted using the Geno2Pheno algorithm. Results: At baseline the median CD4 cell count was 30 cells/mm3. Among the 170 patients assessable in this virological substudy, HIV-1 RNA tropism was as follows: 60% of viruses were R5 and 40% were R5X4/X4. HIV-1 DNA tropism was as follows: 54% were R5 and 46% were R5X4/X4. At week 24, 39% and 49% of patients experienced VF in the enfuvirtide and control arms, respectively. In the enfuvirtide arm, only resistanceassociated mutations to enfuvirtide were detected. In the control arm, two patients displayed drug-resistant viruses at the time of VF. No impact of baseline tropism was observed on immunovirological response, regardless of the study arm. Among the 25 patients experiencing DNA tropism switch between baseline and week 24, 16 (64%) switched from R5 to R5X4/X4. These latter were mostly successfully suppressed patients receiving enfuvirtide and exhibiting poorer immunological response. Conclusions: Baseline RNA tropism had no impact on the immunovirological response. Drug resistance mutations were only detected for the fusion inhibitor. Finally, the mechanism of replenishment of the viral cellular reservoir with X4 viruses observed needs to be further analysed. © The Author 2012.

Melioidosis is an endemic disease in Southeast Asia and northern Australia. It habitually affects immune-depressed hosts and may have a wide range of clinical manifestations. The use of positron emission tomography-computed tomography (PET-CT) has not been described previously for this disease. We report the case of a European traveler without comorbidities who developed melioidosis with pulmonary and bone marrow involvement 1 year after exposure. Antibiotic treatment was managed by taking into account the evolution on PET-CT. We review the literature and suggest the use of PET-CT for the initial evaluation of melioidosis, especially to look for a bone location, and to manage the length of antibiotic therapy. © 2013 International Society for Infectious Diseases.

Objective: We examined if the CNS Penetration-Effectiveness (CPE) score of antiretroviral drugs was associated with survival after a diagnosis of HIV-related encephalopathy, progressive multifocal leukoencephalopathy (PML), cerebral toxoplasmosis, or cryptococcal meningitis. Methods: Using data from the FHDH-ANRS CO4, we compared the survival of 9,932 HIV-infected patients diagnosed with a first neurologic AIDS-defining event in the pre-combination antiretroviral therapy (cART) (1992-1995), early cART (1996-1998), or late cART (1999-2004) periods. Follow-up was subdivided (CPE < 1.5 and CPE 1.5), and relative rates (RR) of death were estimated using multivariable Poisson regression models. Results: In the pre-cART and early cART periods, regimens with CPE 1.5 were associated with lower mortality after HIV-related encephalopathy (RR 0.64; 95% confidence interval [CI] 0.47-0.86 and RR 0.45; 95% CI 0.35-0.58) and after PML (RR 0.79; 95% CI 0.55-1.12 and RR 0.45; 95% CI 0.31-0.65), compared to regimens with CPE < 1.5, while in the late cART period there was no association between the CPE score and the mortality. A higher CPE score was also associated with a lower mortality in all periods after cerebral toxoplasmosis (RR 0.68, 95% CI 0.56-0.84) or cryptococcal meningitis (RR 0.50, 95% CI 0.34-0.74). Whatever the neurologic event, these associations were not maintained after adjustment on updated plasma HIV-RNA (missing, <500, 500 copies/mL) with RR ranging from 0.82 (95% CI 0.36-1.91) to 1.02 (0.69-1.52). Conclusion: At the beginning of the cART era, the CPE score was of importance for survival after severe neurologic event, while in the late cART period, the additional effect of CPE score vanished with more powerful antiretroviral regimens associated with plasma viral load control.

Context: Human lipodystrophies are characterized by loss of adipose tissue, insulin resistance, and metabolic complications. The mechanisms linking fat loss to severe insulin resistance remain unclear. Adipokines may have important roles as intermediary players in metabolism. Objective: Wesought to determine the plasma concentrations of leptin and adiponectin in patients with Berardinelli-Seip congenital lipodystrophy (BSCL) harboring mutations in the genes encoding either 1-acylglycerol-3-phosphate-O-acyltransferase-2 (AGPAT2) or BSCL2/seipin, in comparison with patients with other forms of inherited or acquired lipodystrophies or insulin receptor alterations. Design: Leptin and total and high-molecular-weight adiponectin were measured in plasma of 16 BSCL1/AGPAT2 and 19 BSCL2/seipin patients and compared with heterozygous (n = 22) or nonmutated relatives (controls, n = 30); patients with Dunnigan-type partial lipodystrophy due to lamin A/C mutations (n = 23), HIV-related lipodystrophy (n = 124), and insulin receptor dysfunctions caused by mutations or autoantibodies (n = 17). Results: Leptin was dramatically decreased in BSCL patients as compared with other subgroups. Adiponectin was decreased in BSCL as compared with controls and patients with altered insulin receptor but was discrepant between the two BSCL subgroups. Whereas total and high-molecular-weight adiponectin levels were almost undetectable in BSCL1/AGPAT2 patients, higher levels were detected in BSCL2/seipin patients, comparable with those of patients with partial lipodystrophy. Adiponectin greater than 1.6 mg/liter had a100%negative predictive value for AGPAT2 mutations in inherited lipodystrophies. Conclusions: The presence of circulating adiponectin in BSCL2/seipin patients with near absence of adipose tissue outlines the complexity of adiponectin biology. Use of circulating adiponectin might be helpful to guide the genetic investigations in BSCL. Copyright © 2010 by The Endocrine Society. Source

OBJECTIVE: To describe features of reactive haemophagocytic syndrome (RHS) in HIV-1-infected adult patients. To compare characteristics of patients with malignancy-associated RHS and infection-associated RHS. DESIGN AND SETTING: Retrospective study in three departments of Infectious Diseases/Internal Medicine at three French tertiary centres. PATIENTS AND METHODS: Medical charts of HIV-1-infected adult patients and RHS seen between January 2006 and December 2007 were reviewed. Demographic, clinical and laboratory data obtained at the time of RHS episode were compared between patients with malignancy-associated RHS and infection-associated RHS using non-parametric tests. The overall survival was assessed using the Kaplan-Meier method. RESULTS: Fifty-eight HIV-1-infected patients were diagnosed with RHS [certain RHS n = 43, possible RHS n = 15, median (range) age 42 (23-85) years, men 76%]. At time of RHS, the median duration of HIV infection was 4 (0-22) years and 57% received HAART. The median CD4 lymphocyte count was 91 (2-387)/μl and 35% of patients had a plasma HIV-1 RNA less than 50 copies/ml. Underlying haemopathy/malignancy (Hodgkin lymphoma n = 10) or infection (tuberculosis n = 9, cytomegalovirus infection n = 5) were evidenced for 31 and 23 patients, respectively. Patients with haemopathy/malignancy-associated RHS presented more frequently with splenomegaly (97 vs. 70%, P < 0.01), lower aspartate aminotransferase (36 vs. 84 UI/l, P < 0.01) and lactate dehydrogenase (530 vs. 911 UI/l, P < 0.01) levels and CD8 cell count (234 vs. 588/μl, P < 0.01). Eighteen (31%) patients died. The overall survival was not statistically different between the two groups (P = 0.68). CONCLUSION: In the HAART era, RHS is frequently associated with underlying haemopathy/malignancy, especially Hodgkin lymphoma. The prognosis remains poor but seems, however, better than in the pre-HAART era. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source
