[Choice of initial regimen for antiretroviral-naïve HIV patients: Analysis of motivation]. / Analyse des motivations du choix des antirétroviraux (ARV) prescrits chez des patients infectés par le VIH (PVVIH) naïfs.

OBJECTIVE: Several therapeutic combination antiretroviral therapy regimen are available for initial treatment in naïve HIV infected patients. The choice of a particular regimen remains often subjective. The aim of this study was to determine factors associated with the choice of molecules in initial ARV prescriptions. METHODS: From 01/01 to 30/10/2014, every initial cART prescription was analyzed regarding patients and physicians characteristics. Then, prescriptions were evaluated by an independent committee of ART prescribers. RESULTS: One hundred and thirty two consecutive initial prescriptions by 34 physicians of 11 medical centers were included: 71 M, migrants: 57 %, MSM: 21 %, CD4<200/mm3: 26 %, HIV RNA>100 000 cp/mL (33 %). cART regimen were: NRTI/PI (43 %), NRTI/NNRTI (29.5 %), NRTI/integrase inhibitor (23 %). 75 % of initial cART regimen were consistent with expert guidelines recommendations. The choice of initial cART was not influenced by the type of HIV contamination risk group, patient's geographic origin, CD4 levels. In contrast, working or not (P=0.007), pregnancy wish (P=0.07), pregnancy (P=0.001), HIV RNA levels (P=0.02) and HIV primary infection (P=0.049) influenced the initial choice. Neither physician's age, nor physician's experience influenced this choice. The prescription's non accordance to 2013 French guidelines was mainly related to integrase inhibitor utilisation (P= 0.0001). CONCLUSION: Overall, cART initial choice is mostly consistent with guidelines. Primary HIV infection, procreation features and high viral load are the main factors influencing this choice. New regimen with better tolerability is prescribed even if it is not yet included in the guidelines.

Pulmonary capillary blood volume in patients with probable pulmonary Kaposi's sarcoma.

BACKGROUND: An increase in pulmonary capillary blood volume secondary to angiogenesis has been described in Kaposi's sarcoma. The value of the pulmonary capillary blood volume as an early marker of pulmonary Kaposi's sarcoma was evaluated. METHODS: In a prospective study 45 HIV positive patients (nine asymptomatic for Kaposi's sarcoma, 29 with cutaneous or mucocutaneous Kaposi's sarcoma, and seven with pulmonary Kaposi's sarcoma), underwent pulmonary function tests and determination of transfer capacity for carbon monoxide (TLCO) with its components, pulmonary capillary volume and membrane factor. RESULTS: Total lung capacity (TLC), TLCO, and its components were similar in the three groups. TLCO was normal in patients with pulmonary Kaposi's sarcoma and no changes in membrane factor or pulmonary capillary volume were observed. CONCLUSION: Pulmonary function tests and pulmonary capillary volume alone are not useful for identifying patients with pulmonary Kaposi's sarcoma.

Pulmonary function tests in HIV-infected patients.

OBJECTIVE: To evaluate alterations in lung function during the course of HIV infection. DESIGN: Total lung capacity (TLC), the ratio of forced expiratory volume in one second to vital capacity (FEV1/VC), the carbon monoxide transfer factor (TLCO) and the alveolar-arterial oxygen gradient [delta (A-a)O2] were determined in this retrospective study. PATIENTS: Pulmonary function tests (PFT) were performed on 331 patients at various stages of HIV infection. Patients with a history of intravenous drug use or Kaposi's sarcoma were excluded. RESULTS: No significant differences were observed between the results for asymptomatic patients and those with AIDS-related complex (ARC). TLC, delta (A-a)O2 and TLCO were greatly altered in patients with acute Pneumocystis carinii pneumonia (PCP). No significant differences were observed in the TLC, delta(A-a)O2 or TLCO results between AIDS patients with no history of PCP and those with a history of a single episode of PCP. TLCO was significantly lower (P < 0.001) in AIDS patients with one previous episode of PCP than in the patients with ARC. Interestingly, both TLC and TLCO were significantly lower in the AIDS patients with no history of PCP than in the patients with ARC. Follow-up of 28 patients at different stages of HIV infection confirmed the alteration of PFT results in the late stages. CONCLUSIONS: The reasons for alterations in PFT results in PCP-free AIDS patients remain to be determined. Our findings suggest that PFT can provide valuable information throughout the course of HIV infection, particularly with regard to the indication for bronchoalveolar lavage.
