BackgroundThe long-term efficacy of Highly Active Antiretroviral Therapies (HAART) has enlightened the crucial role of health-related quality of life (HRQL) among HIV-infected patients. However, any analysis of such extensive longitudinal data necessitates a suitable handling of dropout which may correlate with patients–health status.MethodsWe analysed the HRQL evolution over 5 years for 1,000 patients initiating a protease inhibitor (PI)-containing therapy, using MOS SF-36 physical (PCS) and mental (MCS) scores. In parallel with a classical separate random effects model, we used a joint parameter-dependent selection model to account for non-ignorable dropout.ResultsHRQL evolved according to a two-phase pattern, characterized by an initial improvement during the year following HAART initiation and a relative stabilization thereafter. Immunodepression and self-reported side effects were found to be negative predictors of both PCS and MCS scores. Hepatitis C virus coinfection and AIDS clinical stage were found to affect physical HRQL. Results were not significantly altered when accounting for dropout.ConclusionSuch results, obtained on a large sample of HIV-infected patients with extensive follow-up, underline the need for a regular monitoring of patients–immunological status and for a better management of their experience with hepatitis C and HAART.

Bacteria can induce human lymphomas, whereas lymphoproliferative disorders have been described in patients with Q fever. We observed a lymphoma in a patient with Q fever that prompted us to investigate the association between the 2 diseases. We screened 1468 consecutive patients of the 2004 to 2014 French National Referral Center for Q fever database. The standardized incidence ratios (SIRs) of diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) were calculated comparatively to the 2012 Francim Registry. The presence of Coxiella burnetii was tested using immunofluorescence and fluorescence in situ hybridization using a specific 16S ribosomal RNA probe and genomic DNA probe. Seven patients (0.48%) presented mature B-cell lymphoma consisting of 6 DLBCL and 1 FL. An excess risk of DLBCL and FL was found in Q fever patients compared with the general population (SIR [95% confidence interval], 25.4 [11.4-56.4] and 6.7 [0.9-47.9], respectively). C burnetii was detected in CD68(+) macrophages within both lymphoma and lymphadenitis tissues but localization in CD123(+) plasmacytoid dendritic cells (pDCs) was found only in lymphoma tissues. Q fever patients with persistent focalized infection were found more at risk of lymphoma (hazard ratio, 9.35 [1.10-79.4]). Interleukin-10 (IL10) overproduction (P = .0003) was found in patients developing lymphoma. These results suggest that C burnetii should be added to the list of bacteria that promote human B-cell non-Hodgkin lymphoma, possibly by the infection of pDCs and IL10 overproduction. Screening for early lymphoma diagnosis should be considered in the management of patients with Q fever, especially those with persistent focalized infections.

Abstract The aim of this study was to determine factors associated with complete satisfaction with the care provided (satisfaction with physicians and satisfaction with services and organization) among HIV-infected patients followed up in the French ANRS CO8 APROCO-COPILOTE cohort. Analyses focused on cross-sectional data collected during the ninth year of cohort follow-up. Satisfaction with care, sociodemographic characteristics, and behavioral data were collected using self-administered questionnaires, while clinical data were derived from medical records. Complete satisfaction with care was defined as being 100% satisfied. Two logistic regression models were used to identify predictors of (1) complete satisfaction with physicians (n=404) and (2) complete satisfaction with services and organization (n=396). Sixteen percent of patients were completely satisfied with physicians, while 15.9% were completely satisfied with services and organization. Being older and reporting fewer discomforting antiretroviral therapy (ART) side effects were factors independently associated with complete satisfaction with both physicians and services and organization. Strong support from friends and absence of hepatitis C (HCV) co-infection were independently associated with complete satisfaction with physicians, while strong support from ones family and comfortable housing conditions were independently associated with complete satisfaction with services and organization. Even after nine years of follow-up, social vulnerabilities still strongly influence HIV-infected patients’ interactions with the health care system. Day-to-day experience with the disease, including perceived treatment side effects, appears to play a key role in the quality of these interactions. More attention should be given to patient satisfaction, especially for socially vulnerable patients, in order to avoid potentially detrimental consequences such as poor adherence to ART.

BACKGROUND Coxiella burnetii endocarditis is considered to be a late complication of Q fever in patients with preexisting valvular heart disease (VHD). We observed a large transient aortic vegetation in a patient with acute Q fever and high levels of IgG anticardiolipin antibodies (IgG aCL). Therefore, we sought to determine how commonly acute Q fever could cause valvular vegetations associated with antiphospholipid antibody syndrome, which would be a new clinical entity. METHODS We performed a consecutive case series between January 2007 and April 2014 at the French National Referral Center for Q fever. Age, sex, history of VHD, immunosuppression, and IgG aCL assessed by enzyme-linked immunosorbent assay were tested as potential predictors. RESULTS Of the 759 patients with acute Q fever and available echocardiographic results, 9 (1.2%) were considered to have acute Q fever endocarditis, none of whom had a previously known VHD. After multiple adjustment, very high IgG aCL levels (>100 immunoglobulin G-type phospholipid units; relative risk [RR], 24.9 [95% confidence interval {CI}, 4.5-140.2]; P = .002) and immunosuppression (RR, 10.1 [95% CI, 3.0-32.4]; P = .002) were independently associated with acute Q fever endocarditis. CONCLUSIONS Antiphospholipid antibody syndrome with valvular vegetations in acute Q fever is a new clinical entity. This would suggest the value of systematically testing for C. burnetii in antiphospholipid-associated cardiac valve disease, and performing early echocardiography and antiphospholipid dosages in patients with acute Q fever.

Objectives To study the association between CD4/CD8 ratio and morbidity in HIV-infected patients on antiretroviral therapy (ART). Methods The APROCO/COPILOTE cohort enrolled patients initiating a protease inhibitor-containing ART in 1997–1999. The association between occurrence of first non AIDS-defining severe events (NADE) and time-dependent measures of immune restoration was assessed by 4 Cox models with different definitions of restoration, CD4+ cell counts (CD4), CD4/CD8 ratio, both CD4 and CD4/CD8 ratio, or a composite variable (CD4< 500/mm3, CD4 > 500/mm3 and CD4/CD8 ratio < 1, CD4 > 500/mm3 and CD4/CD8 ratio > 1). Models adjusted on baseline characteristics and time-dependent viral load were compared using Akaike Information Criterion. Results We included 1227 patients. Median duration of follow-up was 9.2 years (IQR: 4.2–11.4). Median CD4 was 530/mm3 at 9 years. Median CD4/CD8 ratio was 0.3 (IQR: 0.2–0.5) at baseline and 0.6 (IQR: 0.4–0.9) after 9 years. Incidence of first NADE was 7.4/100 person-years, the most common being bacterial infections (21%), cardiovascular events (14%) and cancers (10%). For both bacterial infections and cardiovascular events, the CD4/CD8 ratio did not add predictive information to the CD4 cell count. However, low CD4/CD8 ratio was the best predictor of non-AIDS cancers (adjusted HR = 2.13 for CD4/CD8 < 0.5; 95% CI = 1.32–3.44). Conclusions CD4/CD8 ratio remains < 1 in most HIV-infected patients despite long-term CD4+ cell counts restoration on ART. A CD4/CD8 ratio < 0.5 could identify patients who require a more intensive strategy of cancer prevention or screening.

In recent years, France has witnessed both structural changes in the population of people living with HIV and a relative improvement in the social representation of HIV infection. However, potential changes in peoples day-to-day experience with HIV have not been documented. We used data from the national surveys ANRS-VESPA (2003) and VESPA2 (2011) to compare the levels and patterns of correlates of health-related quality of life (HRQL) in adult HIV-infected patients followed up in French hospitals over a period of eight years. Mean physical and mental SF-12 scores were compared (VESPA, n = 2072; and VESPA2, n = 2267) using analysis of variance (ANOVA) F tests. Heckman regression models were then used to identify independent correlates of physical and mental quality of life in the two surveys, while accounting for possible bias due to missing score values. A common set of potential socio-demographic, clinical, behavioral, and psychosocial correlates was tested. Individuals reported a decrease in physical quality of life in VESPA2 compared with VESPA (mean score (standard error): 47.5 (0.2) versus 49.6 (0.2), p < .0001), and better mental HRQL (44.3 (0.3) versus 42.3 (0.3), p < 0.0001). In both surveys, financial difficulties and patient-perceived experience of rejection behaviors by medical staff were independently associated with impaired physical and mental quality of life. Older age and unemployment were independently associated with impaired physical quality of life. Immigrants from Sub-Saharan Africa reported better mental quality of life. Findings show that quality of life levels in adult HIV-infected patients followed up at hospital in France has significantly, yet modestly, changed in recent years. However, the pattern of quality of life correlates has remained relatively stable. The impact of patient–provider relationships on self-reported outcomes is confirmed. Further research is needed to identify potential differences in quality of life correlates in specific subgroups of patients, such as men who have sex with men, women, immigrants, and injecting drug users.

Abstract The majority of HIV-infected people in sub-Saharan Africa are women, many of reproductive age. Cameroon is severely hit by the AIDS epidemic and has developed a large national program for improving access to antiretroviral treatment (ART). The reproductive intentions of women living with HIV/AIDS (WLHA) who obtain access to ART in this country remain poorly documented. Our study aimed at exploring factors associated with the desire to have a child among 1433 ART-treated fertile WLHA aged <50. Analyses were based on data collected during the national cross-sectional survey EVAL (ANRS 12-116), which was conducted between September 2006 and March 2007 in 27 HIV care centers in Cameroon. Logistic regression was used to explore factors associated with womens desire to have a child, defined as reporting the wish to have a/another child. A total of 791 women (55%) reported the desire to have a child. After adjusting for age, matrimonial status, number of biological children, and sexual activity, the main factors independently associated with this desire in a multivariate analysis were having a good physical health-related quality of life (1.02 [1.01–1.03] for a one-point increment on the 12-item Short-Form Health Survey scale) and a CD4 count at ART initiation <200 cells/mm3 (1.7 [1.2–2.4]). As a conclusion, the desire to have a child is frequent among ART-treated WLHA in Cameroon. HIV care and family planning programs should be integrated more thoroughly in order to support WLHAs reproductive choices.
