Short-course antibiotic treatment of bone and joint infections in children: a retrospective study at Montpellier University Hospital from 2009 to 2013.

BACKGROUND: Acute haematogenous bone and joint infections (AHBJI) represent a diagnostic and therapeutic emergency in children, with significant potential sequelae in the case of delayed treatment. Although historically the recommendations for treatment have been based on surgery and prolonged antibiotic therapy, recent studies have demonstrated that short-course antibiotic therapy is also effective. OBJECTIVES: We evaluated a short-term antibiotic protocol for both osteomyelitis and septic arthritis in a 6 year retrospective study at the University Hospital of Montpellier. METHODS: This protocol was based on an initial intravenous treatment with a re-evaluation after 48 h and an early switch to oral therapy in the case of a favourable clinical course for a minimum total duration of 15 days. Antibiotics were selected based on local microbiological epidemiology and systematically adapted to bacteriological results. RESULTS: One hundred and seventy-six cases of AHBJI were included, comprising 56 patients with osteomyelitis, 95 with septic arthritis and 25 who had both of these. The aetiological agent was identified in 42% of the cases, with the main pathogens being Staphylococcus aureus (39%) and Kingella kingae (27%). The mean intravenous treatment duration was 4 days, while the total treatment duration was 15 days. There were no treatment failures, mild sequelae occurred in 1% of the cases and the secondary surgical revision rate was 7%. CONCLUSIONS: The results of this study are comparable to those reported for evaluations of prolonged antibiotic therapy protocols, thus indicating that a common short-term antimicrobial therapy for the management of both osteomyelitis and septic arthritis (minimum of 15 days) is a viable option for treating AHBJI in children. Further prospective studies to confirm these findings are hence warranted.

Implementing screening, brief intervention and referral to treatment in a French cohort of people living with HIV: a pilot study.

OBJECTIVES: Screening, brief intervention and referral to treatment (SBIRT) is an evidence-based practice used to identify, reduce and prevent problematic use and abuse of, and dependence on, tobacco, alcohol and psychoactive substances. To date, the pertinence of this practice among people living with HIV (PLHIV) is unknown. In this pilot study, we aimed to assess the acceptability of SBIRT in a cohort of HIV-infected out-patients who were asked about their consumption of alcohol, tobacco and psychoactive substances. METHODS: A monocentric study was performed at the University Hospital of Montpellier. In a 6-month period, 20 trained physicians screened for the consumption of alcohol [using the Alcohol Use Disorders Identification Test (AUDIT)], tobacco (using the Short Fagerstrom Test) and psychoactive substances [using the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) V3.0] via an auto-questionnaire and proposed a brief intervention to patients with misusage. RESULTS: One thousand and eighteen PLHIV completed the questionnaire, and 861 [84.6%; 95% confidence interval (CI) 82.2-86.7%] PLHIV returned it to the physician. Among the latter, 650 patients wished to discuss the answers with their physician (75.5%; 95% CI 72.5-78.3%), and brief interventions were realized in 405 patients (62.3%). CONCLUSIONS: SBIRT is a simple screening and harm reduction tool that is well accepted by PLHIV in out-patient clinics. This method could be implemented in routine HIV care to screen and manage patients systematically for harmful substance use.

Patient-controlled oral analgesia versus nurse-controlled parenteral analgesia after caesarean section: a randomised controlled trial.

We assessed the effectiveness of early patient-controlled oral analgesia compared with parenteral analgesia in a randomised controlled non-inferiority trial of women undergoing elective caesarean section under regional anaesthesia. Seventy-seven women received multimodal paracetamol, ketoprofen and morphine analgesia. The woman having patient-controlled oral analgesia were administered four pillboxes on the postnatal ward containing tablets and instructions for self-medication, the first at 7 h after the spinal injection and then three more at 12-hourly intervals. Pain at rest and on movement was evaluated using an 11-point verbal rating scale at 2 h and then at 6-hourly intervals for 48 h. The pre-defined non-inferiority limit for the difference in mean pain scores (patient-controlled oral analgesia minus parenteral) was one. The one-sided 95% CI of the difference in mean pain scores was significantly lower than one at all time-points at rest and on movement, demonstrating non-inferiority of patient-controlled oral analgesia. More women used morphine in the patient-controlled oral analgesia group (22 (58%)) than in the parenteral group (9 (23%); p = 0.002). The median (IQR [range]) number of morphine doses in the patient-controlled oral analgesia group was 2 (1-3 [1-7]) compared with 1 (1-1 [1-2]); p = 0.006) in the parenteral group. Minor drug errors or omissions were identified in five (13%) women receiving patient-controlled oral analgesia. Pruritus was more frequent in the patient-controlled oral analgesia group (14 (37%) vs 6 (15%) respectively; p = 0.03), but no differences were noted for other adverse events and maternal satisfaction. After elective caesarean section, early patient-controlled oral analgesia is non-inferior to standard parenteral analgesia for pain management, and can be one of the steps of an enhanced recovery process.

Are healthcare workers at higher risk of HIV infection than the general population in Burkina Faso?

In order to assess the HIV prevalence in healthcare workers (HCWs) in Burkina Faso, we conducted a national survey in 97 health facilities from urban and rural areas. Of 1570 HCWs who agreed to participate, 1013 (64·5%) provided a urine sample for HIV testing. The crude prevalence of HIV in HCWs was 3·5% (95% CI 2·3-4·6). HIV prevalence was 0·7% in students and trainees, 3·8% in nurses and midwives, 4·5% in administrative workers, and 4·6% in laboratory workers. After age and area standardization, men from the Demographic Health Survey (DHS) had a similar HIV prevalence (2·3%, 95% CI 1·4-2·9) as male HCWs (2·5%, 95% CI 1·1-4·0), while female HCWs were more infected (4·5%, 95% CI 2·5-6·0) than women from the DHS (2·1%, 95% CI 1·3-2·4). A voluntary counselling and testing (VCT) programme should be specifically implemented and adapted for female HCWs.

[Determinants of low birth weight among newborns to HIV-infected mothers not eligible for antiretroviral treatment in Africa]. / Déterminants du faible poids de naissance chez des enfants nés de mères séropositives pour le VIH, non éligibles au traitement antirétroviral, en Afrique.

BACKGROUND: Low birth weight (LBW) increases the risk of infant death, but little is known about its rate and determinants among babies born to HIV-infected mothers in sub-Saharan Africa. METHODS: This study was conducted in South Africa, Burkina Faso, Uganda and Zambia, during the recruitment process of the PROMISE-PEP (ANRS 12174) clinical trial. The study sample included 1196 subjects screened between August 2009 and December 2011, respectively 254 in South Africa, 221 in Burkina Faso, 197 in Uganda and 524 in Zambia, all ineligible for antiretroviral therapy. Data were collected during ANRS12174 clinical trial antenatal and postnatal screening visits, and during an inclusion visit for completion of an electronic case report form (eCRF). RESULTS: The mean (±SD) age of mothers was 27±5years and their mean CD4 count was 576±195cells/µL. Most mothers lived in a couple (78.7%), had no employment (72.3%) and had a good level of education (74% had gone to school). Male newborns predominated (51.7%). The mean birth weight was 3043g±435g, and 7.8% ([95%CI: 6.3%-9.3%]) of newborns weighed less than 2500g. In univariate analyses, being married or cohabiting, body mass index, WHO HIV disease stage II, female newborn and low gestational age were associated with risk of LBW. In multivariate regression model, low gestational age (aOR=3.74, P<0.0001) and female newborn (aOR=1.63, P=0.04) were significantly associated with LBW. CONCLUSION: The risk factors for LBW found in HIV-infected women ineligible for antiretroviral therapy were the same as in the general population. There was no evidence of additional risk factors associated with HIV infection.

Long-term hepatitis B virus surface antigen decay in HIV-1/hepatitis B virus-coinfected adults initiating a tenofovir-containing regimen.

Hepatitis B virus (HBV) surface antigen (HBsAg) decay was explored in HIV-1- and HBV-coinfected patients beginning antiretroviral (ARV) therapy containing tenofovir disoproxil fumarate (TDF). The mean HBsAg decay was 0.38 log(10) IU/ml/year (95% confidence interval [CI], 0.71 to 0.05) in 18 patients with sustained plasma HIV-1 RNA suppression and 0.15 log(10) IU/ml/year (0.21 to 0.09) in 12 patients experiencing HIV-1 virologic failure due to suboptimal adherence to ARV (P = 0.17). We estimated that six of these 18 patients will attain HBsAg values below 10 IU/ml after 10 years of treatment.

[Do commercial sex workers who discuss treatment with family and friends adhere to it better?]. / Communiquer avec son entourage sur son traitement aide-t-il les femmes impliquées dans le commerce du sexe à l'observer?

INTRODUCTION: The number of HIV trials in Africa is increasing, and they target population groups with high HIV incidence, such as sex workers. Little information, however, is available about the adherence to long-term therapy among such marginalized groups with few economic resources and poor social and family support. A project called "Yerelon" ("know herself" in the Dioula language) began in 1998 in Bobo-Dioulasso to improve the health of women involved in commercial sex through STI/HIV prevention and care adapted to them. This study was conducted before introducing long-term treatment to the population, to assess the effect of communication with those around them on the capacity of these vulnerable women to adhere to drug prescriptions. METHODS: The study was based on interviews conducted during the pilot phase of a 3-month trial of vitamins with potential participants. It concerned two groups of women: one group was infected with HIV (N = 22), the other was not (N = 20); all women in both groups were infected by HSV-2, however. For 5 weeks, the two psychologists of the study team in charge of adherence assessment carried out weekly in-depth interviews with the participants. The qualitative data analysis was organised around several themes. The data were related to aspects of communication with family and friends, serologic results, and adherence. RESULTS: According to our definition of communication about treatment, 20 participants communicated with their family and friends; adherence was good for all but three of them. Women who reported that they were married or living with someone (7/42) nearly all spoke about the study treatment (06/07) with him. Of 16 participants living in a family, 10 communicated with them about the treatment. On the other hand, as seems logical, single women who lived alone spoke less often about the treatment with family and friends (04/19). Talking about the treatment did not appear to involve the family or friends in the treatment; no one reminded any participant, whether she lived alone or in a family, to take her medicine. Nor did this discussion seem "helpful" to any of the women. Twenty-two participants hid the study treatment from family and friends; adherence was good for all but two of these. Social management of the treatment was related to HIV serologic status and relationships with family and friends. Concern about gossip about HIV status made it difficult to integrate the treatment into conversation. Those who did not agree to communicate with their family about the treatment did not even take the drug in the sight of the others. Sometimes, refusal to communicate was aimed at avoiding disapproval when the family did not have a favorable perception of prolonged treatment. Hiding the treatment was not an obstacle to good adherence. Adherence was related to perception of the treatment more than to communication about it. CONCLUSION: Adherence was similar in cases with and without communication. It appeared that these marginalized women, without social networks, were able to adhere correctly to a long-term treatment. To minimize the risks of non-adherence, the support system planned must take into account the factors influencing perceptions of the drug. Specific psychological support centered on the relation with the drug appears necessary during treatment initiation and follow up.

Effect of HIV-1 and antiretroviral therapy on herpes simplex virus type 2: a prospective study in African women.

OBJECTIVES: To document the natural history of herpes simplex virus type 2 (HSV-2) in relation to HIV and highly active antiretroviral therapy (HAART) in Africa, a longitudinal study was conducted of women in the placebo arms of two randomised controlled trials of HSV-suppressive therapy in Burkina Faso. METHODS: 22 HIV-uninfected women (group 1), 30 HIV-1-infected women taking HAART (group 2), and 68 HIV-1-infected women not eligible for HAART (group 3) were followed over 24 weeks. HSV-2 DNA was detected on alternate weeks using real-time PCR from cervicovaginal lavages. Plasma HIV-1 RNA was measured every month. CD4 cell counts were measured at enrollment. RESULTS: Ulcers occurred on 1.9%, 3.1% and 7.2% of visits in groups 1, 2 and 3 (p = 0.02). Cervicovaginal HSV-2 DNA was detected in 45.5%, 63.3% and 67.6% of women (p = 0.11), and on 4.3%, 9.7% and 15.5% of visits in the three groups (p<0.001). Among HIV-infected women, cervicovaginal HSV-2 DNA was detected more frequently during ulcer episodes (adjusted risk ratio (aRR) 2.79, 95% CI 2.01 to 3.86) and less frequently among women practising vaginal douching (aRR 0.60, 95% CI 0.40 to 0.91). Compared with women not taking HAART and with CD4 cell counts of 500 cells/microl or greater, women on HAART had a similar risk of HSV-2 shedding (aRR 0.95, 95% CI 0.52 to 1.73), whereas women with CD4 cell counts of 200-500 cells/microl were more likely to shed HSV-2 (aRR 1.71, 95% CI 1.02 to 2.86). CONCLUSIONS: HSV-2 reactivations occur more frequently among HIV-infected women, particularly those with low CD4 cell counts, and are only partly reduced by HAART. HSV therapy may benefit HIV-infected individuals during HAART.

Longitudinal effect following initiation of highly active antiretroviral therapy on plasma and cervico-vaginal HIV-1 RNA among women in Burkina Faso.

BACKGROUND: Highly active antiretroviral therapy (HAART) could decrease HIV-1 transmissibility by reducing genital and plasma HIV-1 RNA. METHODS: We evaluated the effect of HAART on genital and plasma HIV-1 RNA in a cohort of 39 antiretroviral-naïve women in Burkina Faso. Cervico-vaginal lavages were collected before HAART initiation and at six visits over 28 weeks while on HAART. Blood samples were collected at baseline and at three and four visits for CD4 and plasma HIV-1 RNA measurements, respectively. RESULTS: Before HAART, 72% of women had detectable genital HIV-1 RNA. After 18 weeks on HAART, only one woman (2.5%) had detectable plasma HIV-1 RNA and two women (5.1%) had detectable genital HIV-1 RNA. Similar results were observed at each follow-up visit. However, 16/34 (47%) women with consistently undetectable plasma HIV-1 RNA shed HIV-1 at least once between weeks 18 and 28. In samples with detectable genital HIV-1, the mean quantity of HIV-1 RNA decreased from 3.87 prior to HAART to 3.04 log(10) copies/mL at last visit (median 29 weeks; a 6.8-fold decrease in absolute number of copies/mL) (p = 0.04). A significant median CD4 lymphocyte cell gain of 121 cells/muL (interquartile range 59 to 204) was measured between pre-HAART and last visit. CONCLUSION: These findings suggest that HAART could play a role in reducing HIV transmission in Africa; however, they underscore the need to emphasise safe sex practices with patients taking HAART.

Effect of intra-articular Botulinum toxin injections on temporo-mandibular joint pain.

Temporo-mandibular joint dysfunction can be painful and disabling. In some cases, it is refractory to classical treatment. Intra-articular Botulinum toxin injections have been shown to have an anti-inflammatory and analgesic effect. The aim of this study was to evaluate the effectiveness of such injections on severe, refractory temporo-mandibular joint pain. This was a retrospective study. Patients were included if they still had joint pain≥5 on a Visual Analogue Scale following completion of all other treatments. A complete treatment protocol (including physiotherapy, tongue splints, intra muscular injections of Botulinum toxin and injections of hyaluronic acid, excluding surgery) having being done before the injection of 30 Botox* units (Botulinum toxin A), the treatment being considered clinically successful if the Visual Analogue Scale decreases by at least 2 points. Seventy-seven patients were included. Sixty-six percent of patients have a significant reduction in pain at 1 month which lasted at least until 3 months. Mouth opening and quality of life also improved. Moreover, no complications were reported. Further randomized, controlled studies are needed to confirm the results, however this study suggests intra-articular injection of Botulinum toxin is a safe and effective treatment for severe, refractory temporo-mandibular joint pain, avoiding surgery.

[Anemia, a new severity factor in young infants with acute viral bronchiolitis?] / L'anémie, un nouveau facteur de sévérité de la bronchiolite aiguë du nourrisson ?

INTRODUCTION: The role of anemia is raised as a risk of low respiratory infection of the child, but there are no data on anemia as a severity factor in acute viral bronchiolitis (AVB) in infants. METHODS: All infants less than 16 weeks old admitted to Montpellier University Hospital from 2015/10/01 to 2016/04/01 for AVB were included in a retrospective observational study. The primary objective was to determine whether the hemoglobin (Hb) concentration on admission was an independent factor of clinical severity, judged by the modified Wood's clinical asthma score (m-WCAS). The secondary objective was to assess the impact of Hb level on the characteristics of hospitalization, including the type and duration of respiratory support. RESULTS: The m-WCAS was used at least once during hospitalization in 180 out of 220 patients (82%), making it possible to distinguish patients with mild AVB (maximum m-WCAS<2, n=81) from patients with severe AVB (maximum m-WCAS>2, n=99). A logistic regression model indicated that the Hb concentration, for every 1g/dL decrement, was an independent factor of AVB severity (OR 1.16 [1.03-1.29], P=0.026). A level under 10g/dL on admission was associated with a higher use of continuous positive airway pressure (P<0.001), as well as a longer duration of respiratory support (P=0.01). CONCLUSION: This study suggested that anemia may influence the clinical expression of AVB in young infants.

[Childhood steroid-dependent idiopathic nephrotic syndrome: Predictive factors for the need of immunosuppressive treatment]. / Syndrome néphrotique idiopathique corticodépendant de l'enfant : facteurs prédictifs de recours à un traitement immunosuppresseur.

BACKGROUND AND AIMS: More than half of the children with idiopathic nephrotic syndrome become steroid-dependent (or frequent relapsers) and will later require the use of complementary treatment aiming to reduce steroids' side effects and to limit the number of proteinuria relapses. It appears important to identify these children as early as possible in order to adapt their treatment. The aim of this study was to analyze the population of children, under 18 years of age, diagnosed between 1/01/2000 and 31/05/2015 with an idiopathic nephrotic syndrome and followed at the Montpellier University Hospital to search for criteria predictive of steroid-sparing agent use. METHODS: In this retrospective study of children with idiopathic nephrotic syndrome, the exclusion criteria were primary steroid resistance and children with no proteinuria relapse after diagnosis. RESULTS: Eighty-four children (54 boys) were included in this study. The mean follow-up duration was 5.5 years (0.75-16). The mean age at diagnosis was 4.6 years. Sixty-five children (77%) received at least one steroid-sparing agent during their follow-up, within a mean 10 months after diagnosis. In these patients, the first relapse of the disease occurred earlier when compared with the children who were maintained on steroid alone (4 months vs 7 months; P<0.001). The use of methylprednisolone pulses to obtain a remission, the cumulative dose of steroid treatment, and the number of proteinuria relapses were also significantly correlated with the use of complementary immunosuppressive therapy. CONCLUSION: We found no predictive criteria of the use of steroid-sparing agents at diagnosis in our population of children. Nevertheless, with the steroid regimen used, the time within which the first proteinuria relapse occurred appears to be a significant criterion for the secondary use of a steroid-sparing agent. These data should be taken into account when choosing the treatment regimen.

Early glucose and methylene blue are effective against unripe ackee apple (Blighia sapida) poisoning in mice.

The ingestion of unripe ackee fruit (Blighia sapida) is responsible for lethal epidemic encephalopathy in West Africa and the Caribbean. The treatment of ackee poisoning remains empirical and lethality was 100% in a recent epidemic in Burkina Faso. Because ackee poisoning has certain biochemical similarities to ifosfamide encephalopathy, we evaluated the efficacy of methylene blue (MB) and glucose (G), alone and in combination (MB+G) in mice, as a treatment for ackee poisoning. MB administration showed some efficacy towards early mortality (P=0.07) but not to late mortality. No deaths were observed when 8 mg/kg MB was administrated within 1h of the ackee poisoning. The treatment was ineffective if given 6h or later after poisoning. Survival in G and G+MB groups was higher than in MB group (75% and 25% respectively) (P=0.008, R=2.0, 1.14

Evaluation of an intravenous-endovascular strategy in patients with acute proximal middle cerebral artery occlusion.

BACKGROUND AND PURPOSE: IVT administered in acute ischemic stroke provides low recanalization rates in proximal intracranial occlusions, with consequently poor clinical outcome. The safety and efficacy of an IES by using mechanical thrombectomy after IVT failure were assessed in acute MCA occlusions. MATERIALS AND METHODS: Patients presenting with acute MCA occlusion within 4.5 hours with an NIHSS score between 8 and 25 and a DWI ASPECTS of >5 were eligible. From September 2009 to September 2010, mechanical thrombectomy by using the Solitaire FR device was systematically performed if no clinical improvement was observed 1 hour after the initiation of IVT (IES group). Results in terms of clinical outcome were compared with those from an IVT series from January 2007 to August 2009 (IVT group). RESULTS: Alteplase was administered in 123 patients with proximal intracranial occlusion. Fifty-six had a confirmed MCA occlusion: 32 were included in the IVT group; and 24, in the IES group. At 24 hours, the median NIHSS improvement was 8.5 points in the IES group (25%-75% CI, 1.5-13) and 3 points in the IVT group (25%-75% CI, 1-5) (P = .001). At 3 months, 17/22 (77%) patients from the IES group and 15/30 (50%) from the IVT group had an mRS score of ≤2. After adjustment for confounding variables, IES was strongly associated with favorable clinical outcome (77% versus 50%; adjusted odds ratio = 11.9; 95% CI, 1.6-89.1; P < .02). No symptomatic intracranial hemorrhage was observed. CONCLUSIONS: IES by using systematic mechanical thrombectomy after IVT failure safely improves the clinical outcome at 3 months and could represent an interesting alternative in the management of patients with acute MCA occlusion.

Combining rapid diagnostic tests and dried blood spot assays for point-of-care testing of human immunodeficiency virus, hepatitis B and hepatitis C infections in Burkina Faso, West Africa.

People screened for human immunodeficiency virus (HIV) using rapid diagnostic tests (RDTs) in Africa remain generally unaware of their status for hepatitis B (HBV) and hepatitis C (HCV) infections. We evaluated a two-step screening strategy in Burkina Faso, using both HIV RDTs and Dried Blood Spot (DBS) assays to confirm an HIV-positive test, and to test for HBV and HCV infections. HIV counselling and point-of-care testing were performed at a voluntary counselling and testing centre with HBV, HCV status and HIV confirmation using DBS specimens, being assessed at a central laboratory. Serological testing on plasma was used as the reference standard assay to control for the performance of DBS assays. Nineteen out of 218 participants included in the study were positive for HIV using RDTs. A fourth-generation HIV ELISA and immunoblot assays on DBS confirmed HIV status. Twenty-four out of 25 participants infected with HBV were found positive for hepatitis B surface antigen (HBsAg) using DBS. One sample with a low HBsAg concentration on plasma was not detected on DBS. Five participants tested positive for HCV antibodies were confirmed positive with an immunoblot assay using DBS specimens. Laboratory results were communicated within 7 days to participants with no loss to follow up of participants between the first and second post-test counselling sessions. In conclusion, DBS collection during HIV point-of-care testing enables screening and confirmation of HBV, HCV and HIV infections. Diagnosis using DBS may assist with implementation of national programmes for HBV, HCV and HIV screening and clinical care in middle- to low-income countries.

Roles of clinical and subclinical reactivated herpes simplex virus type 2 infection and human immunodeficiency virus type 1 (HIV-1)-induced immunosuppression on genital and plasma HIV-1 levels.

BACKGROUND: Few longitudinal studies have described the interactions between reactivation of herpes simplex virus type 2 (HSV-2) infection (hereafter, "HSV-2 reactivation") and genital and systemic replication of human immunodeficiency virus type 1 (HIV-1). METHODS: Women in Burkina Faso who were seropositive for both HIV-1 and HSV-2 were enrolled in a randomized placebo-controlled trial of therapy to suppress reactivation of HSV-2 infection (hereafter, "HSV suppressive therapy"). During the baseline phase, 6 enriched cervicovaginal lavage specimens were obtained over 12 weeks to detect and quantify the HIV-1 RNA and HSV-2 DNA loads. RESULTS: Women with genital ulcer disease (GUD) detected at least once were more likely than women in whom GUD was not detected (risk ratio [RR], 1.23; 95% confidence interval [CI], 1.09-1.37) to have genital HIV-1 RNA detected during >or=1 visit. Similarly, women with genital HSV-2 DNA detected during >or=1 clinic visit were more likely than women in whom genital HSV-2 DNA was not detected (RR, 1.17; 95% CI, 1.01-1.34) to have genital HIV-1 RNA detected at least once. In addition, the mean genital HIV-1 RNA loads for women with GUD detected during >or=1 visit and women with HSV-2 genital shedding detected during >or=1 visit were greater than that for women in whom genital HSV-2 DNA or GUD was never detected. The plasma HIV-1 RNA load was increased among women for whom >or=1 visit revealed GUD (+0.25 log(10) copies/mL; 95% CI, -0.05-0.55) or genital HSV-2 DNA (+0.40 log(10) copies/mL; 95% CI, 0.15-0.66), compared with women who did not experience GUD or HSV-2 genital shedding, respectively. The association of HSV-2 reactivations on HIV-1 replication tended to be stronger in patients with a higher CD4(+) cell count (i.e., >500 cells/microL). The contribution of HSV-2 to HIV-1 replication among women with CD4(+) cell count of 500 cells/microL deserves further investigation. CLINICAL TRIALS REGISTRATION: The ANRS 1285 Study is registered with the National Institutes of Health (registration number NCT00158509).

Human papillomavirus genotype distribution and cervical squamous intraepithelial lesions among high-risk women with and without HIV-1 infection in Burkina Faso.

Human papillomavirus (HPV) infection and cervical squamous intraepithelial lesions (SILs) were studied in 379 high-risk women. Human papillomavirus DNA was detected in 238 of 360 (66.1%) of the beta-globin-positive cervical samples, and 467 HPV isolates belonging to 35 types were identified. Multiple (2-7 types) HPV infections were observed in 52.9% of HPV-infected women. The most prevalent HPV types were HPV-52 (14.7%), HPV-35 (9.4%), HPV-58 (9.4%), HPV-51 (8.6%), HPV-16 (7.8%), HPV-31 (7.5%), HPV-53 (6.7%), and HPV-18 (6.4%). Human immunodeficiency virus type 1 (HIV-1) seroprevalence was 36.0%. Human papillomavirus prevalence was significantly higher in HIV-1-infected women (87 vs 54%, prevalence ratio (PR) = 1.61, 95% confidence interval (CI): 1.4-1.8). High-risk HPV types (71 vs 40%, PR = 1.79, 95% CI: 1.5-2.2), in particular HPV-16+18 (22 vs 9%, PR = 2.35, 95% CI: 1.4-4.0), and multiple HPV infections (56 vs 23%, PR = 2.45, 95% CI: 1.8-3.3) were more prevalent in HIV-1-infected women. High-grade SIL (HSIL) was identified in 3.8% of the women. Human immunodeficiency virus type 1 infection was strongly associated with presence of HSIL (adjusted odds ratio = 17.0; 95% CI 2.2-134.1, P = 0.007) after controlling for high-risk HPV infection and other risk factors for HSIL. Nine of 14 (63%) HSIL cases were associated with HPV-16 or HPV-18 infection, and might have been prevented by an effective HPV-16/18 vaccine.

Intrarectal pharmacokinetics of two formulations of quinine in children with falciparum malaria.

OBJECTIVE: To compare the intrarectal bioavailabilities of two parenteral formulations of quinine most available in French- (Cinchona alkaloid mixture) and English (hydrochloride salt) -speaking areas of Africa. METHODS: The pharmacokinetics of quinine was investigated in four groups of 12 children with acute Plasmodium falciparum malaria receiving 8 mg/kg quinine base every 8 h either as hydrochloride salt or Cinchona alkaloid mixture by a slow 4-h intravenous infusion or intrarectal administration. Body temperature and parasitaemia were monitored, and blood quinine concentrations were measured by means of high-performance liquid chromatography. RESULTS: At 72 h, all the children were aparasitaemic and apyretic. Quinine C(max) values were higher after intravenous infusion of the hydrochloride salt and Cinchona alkaloid mixture (6.9+/-1.9 micro g/ml and 5.2+/-1.3 micro g/ml) than after intrarectal administration (3.5+/-1.4 micro g/ml and 3.1+/-1.6 micro g/ml), but t(max) values were similar (3.6+/-1.5, 4.2+/-1.0, 4.0+/-1.9, and 4.7+/-2.0 h, respectively). Intrarectal relative bioavailabilities of hydrochloride salt solution (57%) and Cinchona alkaloid mixture (62%) were similar. CONCLUSION: Whatever the parenteral formulation of quinine, the blood concentration-time profiles of quinine were similar after intrarectal administration. Intrarectal administration of hydrochloride salt solution is a possible mode of quinine delivery in remote rural areas of Africa.

Review of STI and HIV epidemiological data from 1990 to 2001 in urban Burkina Faso: implications for STI and HIV control.

OBJECTIVES: To better understand the sexually transmitted infection (STI)/HIV dynamics in an urban west African setting in order to adapt STI/HIV control efforts accordingly. METHODS: Review of STI and HIV epidemiological studies performed over the past decade in Bobo-Dioulasso, the second city of Burkina Faso. Trends in STI prevalence among commercial sex workers and the general population were assessed over time through studies that used the same recruitment and laboratory diagnostic procedures. Variations in aetiologies of vaginal discharge, urethral discharge, and genital ulcers were also evaluated among patients consulting for genital infection complaints. Antenatal clinic based surveys provided data to assess HIV trend among the general population. RESULTS: We observed an important decline of classic bacterial STI such as syphilis, Neisseria gonorrhoea, Chlamydia trachomatis, and Haemophilus ducrey infections in all study groups. Trichomoniasis also declined but to a lesser extent. HIV infection followed the same trend at the same time, with a significant decline in the 15-19 year age group of pregnant women, suggesting a possible decrease of HIV incidence. Although no evidence of a causal relation can be drawn from this review, adoption of safer sex behaviour, introduction of the syndromic management (SM) approach, or higher antibiotic use may have contributed to these changes. CONCLUSIONS: Classic bacterial STI declined over the past decade in parallel with a stabilisation of HIV infection. Variations in syndromes aetiology and sexual behaviours should be monitored as part of STI surveillance in order to improve STI syndromic management algorithms and to adapt HIV/STI prevention efforts.
