Reasons for not starting antiretroviral therapy in HIV-1-infected individuals: a changing landscape.

PURPOSE: A cross-sectional survey was conducted to better understand why chronically HIV-1-infected individuals stratified by CD4 count (≤349; 350-499; ≥500 cells/µL) were not on antiretroviral therapy (ART). METHODS: Before the consultation, treatment-naive patients and their physicians independently completed a 90-item-questionnaire about barriers and their readiness to start/defer ART. The study was carried out at 34 sites in nine countries in Europe and Australia. RESULTS: Between December 2011 and October 2012, 508 pairs of patient- and physician-questionnaires were completed. 426 (84 %) patients were male and 39 (8 %), 138 (27 %), and 330 (65 %) were in the three stratified groups based on CD4 count, respectively. In the category 'Body and symptoms' the most commonly identified reason for patients not to start was: "As long as I feel good I don't have to take medication" (44 %). Less than 20 % of respondents indicated fears of side effects and toxicity or problems to manage pills. Most patients were in the lowest stage of treatment-readiness (N = 323, 68 %), especially patients with CD4 cells ≥500 cells/µL (N = 240, 79 %). Physicians answered in 92 (18 %) cases that ART was not indicated for CD4 cells <500 cells/µL. Main reasons for physicians not starting treatment for these patients were their perception that patients were 'too depressed' (13 %) or that they had not known them long enough (13 %). CONCLUSIONS: Nowadays patient-barriers to ART are commonly related to health-and treatment-beliefs compared to fear of toxicity or ART manageability in the past. This new barrier pattern seems to reflect the era of well tolerated, easier ART regimens and has to be considered in light of the new recommendations to treat all HIV-infected individuals regardless of the CD4 cell count.

Burden of anemia in patients with osteoarthritis and rheumatoid arthritis in French secondary care.

BACKGROUND: Arthritic disorders can be the cause of hospitalizations, especially among individuals 60 years and older. The objective of this study is to investigate associations between health care resource utilization in arthritis patients with and without concomitant anemia in a secondary care setting in France. METHODS: This retrospective cohort study utilized data on secondary care activity in 2001 from the Programme de Médicalisation des Systèmes d'Information database. Two cohorts were defined using ICD-10 codes: patients with an arthritis diagnosis with a concomitant diagnosis of anemia; and arthritis patients without anemia. Health care resource utilization for both populations was analyzed separately in public and private hospitals. Study outcomes were compared between the cohorts using standard bivariate and multivariable methods. RESULTS: There were 300,865 hospitalizations for patients with arthritis only, and 2,744 for those with concomitant anemia. Over 70% of patients with concomitant anemia were in public hospitals, compared with 53.5% of arthritis-only patients. Arthritis patients without anemia were younger than those with concomitant anemia (mean age 66.7 vs 74.6, public hospitals; 67.1 vs 72.2, private hospitals). Patients with concomitant anemia/arthritis only had a mean length of stay of 11.91 (SD 14.07)/8.04 (SD 9.93) days in public hospitals, and 10.68 (SD 10.16)/9.83 (SD 7.76) days in private hospitals. After adjusting for confounders, the mean (95% CI) additional length of stay for arthritis patients with concomitant anemia, compared with those with arthritis only, was 1.56 (1.14-1.98) days in public and 0.69 (0.22-1.16) days in private hospitals. Costs per hospitalization were €;480 (227-734) greater for arthritis patients with anemia in public hospitals, and €;30 (-113-52) less in private hospitals, than for arthritis-only patients. CONCLUSIONS: Arthritis patients with concomitant anemia have a longer length of stay, undergo more procedures, and have higher hospitalization costs than nonanemic arthritis patients in public hospitals in France. In private hospitals, concomitant anemia was associated with modest increases in length of stay and number of procedures; however, this did not translate into higher costs. Such evidence of anemia-related health care utilization and costs can be considered as a proxy for the clinical significance of anemia.

Severe nucleoside-associated lactic acidosis in human immunodeficiency virus-infected patients: report of 12 cases and review of the literature.

Lactic acidosis is a rare but often fatal complication reported in some human immunodeficiency virus (HIV)-infected patients treated with nucleoside-analogue reverse-transcriptase inhibitors. We report a series of 12 patients with HIV infection treated with nucleoside analogues who developed unexplained metabolic acidosis. We have also reviewed 60 additional published cases. The aim of the present study is to describe the clinical picture, prognostic factors, and final outcome for nucleoside-associated lactic acidosis. The mortality rate is high: 33% for our patients, and 57% for the patients described in the literature. In the multivariate analysis, a lactate serum level of >10 mM (odds ratio [OR], 13.23; 95% confidence interval [CI], 2.96-59.25) was the only factor associated with higher mortality. The administration of specific therapy with cofactors against acidosis was associated with a lower mortality (OR, 0.17; 95% CI, 0.04-0.73). We conclude that specific therapy with cofactors may improve the outcome for patients with this syndrome.
