Background: Suboptimal use of antibiotics is a driver of antimicrobial resistance (AMR). Clinical decision support systems (CDSS) can assist prescribers with rapid access to up-to-date information. In low- and middle-income countries (LMIC), the introduction of CDSS for antibiotic prescribing could have a measurable impact. However, interventions to implement them are challenging because of cultural and structural constraints, and their adoption and sustainability in routine clinical care are often limited. Preimplementation research is needed to ensure relevant adaptation and fit within the context of primary care in West Africa., Objective: This study examined the requirements for a CDSS adapted to the context of primary care in West Africa, to analyze the barriers and facilitators of its implementation and adaptation, and to ensure co-designed solutions for its adaptation and sustainable use., Methods: We organized a workshop in Burkina Faso in June 2019 with 47 health care professionals representing 9 West African countries and 6 medical specialties. The workshop began with a presentation of Antibioclic, a publicly funded CDSS for antibiotic prescribing in primary care that provides personalized antibiotic recommendations for 37 infectious diseases. Antibioclic is freely available on the web and as a smartphone app (iOS, Android). The presentation was followed by a roundtable discussion and completion of a questionnaire with open-ended questions by participants. Qualitative data were analyzed using thematic analysis., Results: Most of the participants had access to a smartphone during their clinical consultations (35/47, 74%), but only 49% (23/47) had access to a computer and none used CDSS for antibiotic prescribing. The participants considered that CDSS could have a number of benefits including updating the knowledge of practitioners on antibiotic prescribing, improving clinical care and reducing AMR, encouraging the establishment of national guidelines, and developing surveillance capabilities in primary care. The most frequently mentioned contextual barrier to implementing a CDSS was the potential risk of increasing self-medication in West Africa, where antibiotics can be bought without a prescription. The need for the CDSS to be tailored to the local epidemiology of infectious diseases and AMR was highlighted along with the availability of diagnostic tests and antibiotics using national guidelines where available. Participants endorsed co-design involving all stakeholders, including nurses, midwives, and pharmacists, as central to any introduction of CDSS. A phased approach was suggested by initiating and evaluating CDSS at a pilot site, followed by dissemination using professional networks and social media. The lack of widespread internet access and computers could be circumvented by a mobile app with an offline mode., Conclusions: Our study provides valuable information for the development and implementation of a CDSS for antibiotic prescribing among primary care prescribers in LMICs and may, in turn, contribute to improving antibiotic use, clinical outcomes and decreasing AMR., (©Nathan Peiffer-Smadja, Armel Poda, Abdoul-Salam Ouedraogo, Jean-Baptiste Guiard-Schmid, Tristan Delory, Josselin Le Bel, Elisabeth Bouvet, Sylvie Lariven, Pauline Jeanmougin, Raheelah Ahmad, François-Xavier Lescure.

Background: The incidence of chronic kidney disease (CKD) is 10 times higher in human immunodeficiency virus (HIV)-infected patients than in the general population. We explored the prevalence and determinants of proximal tubular dysfunction (PTD) in HIV-infected individuals, and assessed the impact of the tubulopathy on the estimated glomerular filtration rate (eGFR) outcome., Methods: A cohort study was performed on 694 outpatients followed in a French centre to analyse the prevalence of PTD, the diagnosis performance of screening tools and the associated factors. eGFR was prospectively evaluated to analyse the predictive value of the tubulopathy on eGFR decrease., Results: At inclusion, 14% of the patients presented with PTD and 5% with CKD. No individual tubular marker, including non-glomerular proteinuria, glycosuria dipstick or hypophosphataemia, registered sufficient performance to identify PTD. We found a significant interaction between tenofovir disoproxil fumarate exposure and ethnicity (P = 0.03) for tubulopathy risk. Tenofovir disoproxil fumarate exposure was associated with PTD in non-Africans [adjusted odds ratio (aOR) = 4.71, P < 10-3], but not in patients of sub-Saharan African origin (aOR = 1.17, P = 0.73). Among the 601 patients followed during a median of 4.3 years, 13% experienced an accelerated eGFR decline. Unlike microalbuminuria and glomerular proteinuria, tubulopathy was not associated with accelerated eGFR decline., Conclusion: PTD is not rare in HIV-infected individuals but is less frequent in sub-Saharan African patients and is associated with tenofovir disoproxil fumarate exposure only in non-Africans. Its diagnosis requires multiple biochemical testing and it is not associated with an accelerated eGFR decline., (© The Author(s) 2019. Published by Oxford University Press on behalf of ERA-EDTA.

Objective: In 2014, the Joint United Nations Program on HIV and AIDS (UNAIDS) and partners set the '90-90-90 targets'. Many countries are facing the challenge of estimating the first 90. Our objective was to propose an alternative modelling procedure, and to discuss its usefulness for taking into account duplication., Results: For deduplication, we identified two important ingredients: the probability for an HIV+ person of being re-tested during the period and average number of HIV+ tests. Other adjusted factors included: the false positive probability; the death and emigration probabilities. The uncertainty of the adjusted estimate was assessed using the plausibility bounds and sensitivity analysis. The proposed method was applied to Cameroon for the period 1987-2016. Of the 560,000 people living with HIV estimated from UNAIDS in 2016; 504,000 out to know their status. The model estimates that 380,464 [379,257, 381,674] know their status (75.5%); thus 179,536 who do not know their status should be sought through the intensification of testing. These results were subsequently used for constructing the full 2016 Cameroon HIV cascade for identifying programmatic gap, prioritizing the resources, and guiding the strategies of the 2018-2022 National Strategy Plan and funding request.

Background: Like many African countries, the issue of sex between men in Burkina Faso remains taboo and sometimes result in social exclusion. This population which is vulnerable to HIV/AIDS is unknown, due to lack of scientific researches., Aim: Our study aimed to characterize knowledge, attitudes and sexual practices and to estimate HIV seroprevalence among men having sex with men (MSM) living in Ouagadougou., Methods: A cross-sectional study was conducted in order to describe and analyze MSM living in Ouagadougou. They were recruited by snowball sampling, aged at least 18 years, and accepted to participate at the study. Data were collected by qualified interviewers through administered questionnaire face to face. HIV test was systematically proposed., Results: A total of 142 MSM were recruited during the study period. The sample was mostly composed of students or pupils (60.8%), single men (91%), with age range 18-30 years (96.5%). The HIV knowledge median score was 8/10. HIV seroprevalence was 8.9% (4.5-15.4)., Conclusion: Our study confirms the vulnerability of MSM living in Ouagadougou about HIV/AIDS given the high rate of HIV seroprevalence. Targeted interventions for prevention, care and scientific research are challenges for the authorities to sustain the achievements of the national fight against HIV and AIDS., (Copyright © 2016 Elsevier Masson SAS.

Objective: To evaluate the vulnerability of male prisoners to HIV, risk behaviour and access to prevention., Methods: This cross-sectional descriptive study was conducted in july and August 2012 in Ouagadougou Prison in Burkina Faso. Two trained investigators collected data by means of individual interviews in the prison visiting room using a questionnaire administered to male inmates 18 years and older, imprisoned for more than three months. Two focus groups were conducted with prison guards and healthcare personnel., Results: A total of165 male prisoners were interviewed. The mean prison sentence was 19 months, the median age of the inmates was 28years and 45% of them were illiterate. About4% of male prisoners reported having had homosexual relations during their imprisonment. However, data indicate underreporting and denial of homosexual behaviour by prisoners. 49% of prisoners shared razors or razorblades in prison. None of the interviewees reported injected drug use or tattoos in prison. The majority (84%) of prisoners had a good knowledge of HIVjAIDS and 6% were aware of the risk of sexually transmitted infections. Only 5% of prisoners had had a screening test during their stay in prison., Conclusion: Prison conditions, homosexual behaviour and absence of condoms in prison accentuate the vulnerability of prisoners to HIV j AIDS. Implementation of a prevention programme and management HIV-positive prisoners would help to reduce significantly the risk of HIV transmission in prison.

Introduction: Gender differences in antiretroviral therapy (ART) outcomes are critical in sub-Saharan Africa. We assessed the association between gender and virologic failure among adult patients treated in a public routine clinic (one of the largest in West Africa) in Burkina Faso., Methods: We performed a case-control study between July and October 2012 among patients who had received ART at the Bobo Dioulasso Day Care Unit. Patients were eligible if they were 15 years or older, positive for HIV-1 or HIV-1+2, and on first-line ART for at least six months. Cases were all patients with two consecutive HIV loads >1000 copies/mL (Biocentric Generic or Abbott Real Time assays), or one HIV load >1000 copies/mL associated with immunologic or clinical failure criteria. Controls were all patients who only had HIV loads <300 copies/mL. The association between gender and virologic failure was assessed using a multivariate logistic regression, adjusted on age, level of education, baseline CD4+ T cell count, first and current antiretroviral regimens and time on ART., Results: Of 2303 patients (74.2% women; median age: 40 years; median time on ART: 34 months), 172 had virologic failure and 2131 had virologic success. Among the former, 130 (75.6%) had confirmed virologic failure, 38 (22.1%) had viro-immunologic failure, and four (2.3%) had viro-clinical failure. The proportion of men was significantly higher among the cases than among the controls (37.2% vs. 24.9%; p<0.001). Compared to controls, cases were also younger, more immunodeficient at ART initiation, less likely to receive a protease inhibitor-based antiretroviral regimen and had spent a longer period of time on ART. After adjustment, male gender remained strongly associated with virologic failure (odds ratio 2.52, 95% CI: 1.77-3.60; p<0.001)., Conclusions: Men on ART appeared more vulnerable to virologic failure than women. Additional studies are needed to confirm the poorer prognosis of men in this setting and to determine the causes for their vulnerability in order to optimize HIV care. From now on, efforts should be made to support the adherence of men to ART in the African setting.

Background and Objectives: The therapy and outcome of HIV infection have dramatically changed over the last 15 years, resulting in a change in renal complications. This study analyzed the characteristics of HIV-infected patients and biopsy-proven tubulointerstitial nephropathies to define disease patterns and therapeutic implications., Design, Setting, Participants, & Measurements: A clinico-pathologic retrospective study of 59 consecutive renal biopsies showing predominant tubular and/or interstitial lesions in HIV-infected patients referred to the nephrology department between 1995 and 2011 was performed. HIV-associated nephropathy and vascular diseases were excluded from the study., Results: Tubulointerstitial nephropathies accounted for 26.6% of 222 native renal biopsies performed in HIV-infected patients. Two pathologic groups were analyzed, tubulopathy and interstitial nephritis, which represented 49% and 51% of tubulointerstitial nephropathies, respectively. Most patients presented with AKI (76.3%) and high-grade proteinuria (57.7%). Drug-related nephrotoxicity was the leading cause (52.5%). Alternative etiologies included infections (15.2%), dysimmune disorders (8.5%), malignancies (3.4%), and chronic (10.2%) and acute (10.2%) tubulointerstitial nephropathies of undetermined origin. Tubulopathy was strongly associated with antiretroviral drug toxicity (75.9%) and mostly caused by tenofovir (55.2%), which was associated with proximal tubular dysfunction (87.5%), overt Fanconi's syndrome (37.5%), and nephrogenic diabetes insipidus (12.5%). Interstitial nephritis was associated with a broader spectrum of pathologic lesions and etiologies., Conclusions: In this series, tubulointerstitial nephropathies accounted for 26.6% of renal diseases in HIV-infected patients. Considering the therapeutic implications of diagnoses of drug toxicity, infection, and dysimmune syndromes, this study underscores the importance of monitoring renal parameters in HIV-infected patients and points to the relevance of kidney biopsy to allow an accurate diagnosis.

Objective: The authors had for aim to assess the prevalence of hepatitis B co-infection in a cohort of HIV-infected patients, routinely followed-up at the Day Care Unit of the Bobo Dioulasso Sanou Souro University Hospital, Burkina Faso., Patients and Methods: The Elisa technique was used to dose HBs antigen (AgHBs), antibodies anti-HBs and anti-HBc in all the patients followed by the biological laboratory, from October to December 2008., Results: The AgHBs prevalence was 12.7% [CI at 95%: 10.7-15.0%] and men were slightly more likely to be positive for AgHBs than women (16.5% [12.0-21.9%] versus 11.6% [9.4-14.1%]; P=0.047); 83.3% of the patients [80.8-85.6%] were positive for hepatitis B core antibody, and 32.6% [29.7-35.6%] for hepatitis B surface antibody; 29.9% of the patients [27.1-32.8%] had a complete profile of former hepatitis B infection, 41.3% [38.2-44.4%] expressed core antibodies only; 13.8% [11.7-16.0%] had a negative serological test, and 2.3% [1.5-3.4%] presented a vaccinal immunity., Conclusion: These results stress the usefulness of screening for hepatitis B in all HIV-infected patients, along with the initial biological tests. This would help adapt HIV treatment to co-infected patients and to build an expanded program of vaccination for non-immune patients., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

The aim of this survey was to assess the HIV risk practices of male prisoners and their access to prevention. This descriptive study took place at the House of Detention and Corrections in Ouagadougou from June through August 2012. In all, 165 prisoners (median age: 28 years, range: 18-65) were interviewed. A low proportion of the prisoners (16%) had accurate knowledge of the modes of HIV transmission. Before imprisonment, their sex lives featured multiple partners, occasional sex, and low condom use. Seven (4%) prisoners reported homosexual relations while in prison. The conditions of incarceration and the denial of homosexual practices at Ouagadougou aggravate prisoners' vulnerability to HIV/AIDS.

Objective: The goal of the study was to assess the activity of a multidisciplinary structure for HIV infected patients, two years after the opening of the day hospital., Design: A retrospective observational study of the Bobo Dioulasso day-hospital was made using the ESOPE (Epiconcept, France) software., Results: In 2002, 147 patients were followed in the Bobo Dioulasso university hospital, 27 (or 18.5 %) of whom were treated with antiretrovirals. Between 2005, opening of the day-hospital, and 2007, the total number of patients increased by 20 %. The number of patients on antiretrovirals rose from 47 to 70 % in the same time. The rate of patients with waved antiretroviral costs rose from 6 to 53 %. Three hundred and eighty-six patients died between 2002 and 2007. 1450 patients were lost to follow-up between 20002 and 2007., Conclusions: Two years after its opening, the Bobo Dioulasso day-hospital manages one of the largest HIV cohort in sub-Saharan Africa and has become a reference structure in Burkina Faso. The analysis of this cohort was an opportunity to identify issues concerning HIV patient treatment in 2009., ((c) 2009 Elsevier Masson SAS. All rights reserved.)

We examined factors associated with virological failure in 310 HIV-infected patients receiving atazanavir (ATV). Independent links were identified with virological failure under ATV: virological failure previous history (P = 0.006) and ATV underdosing (P = 0.04). A maintenance therapy was protective (P = 0.01). The optimal therapeutic ranges of ATV concentration were found to be from 300 ng/ml (or 180 for patients treated with maintenance therapy) to 650 ng/ml for C24 and from 1000 ng/ml (or 500 for patients treated with maintenance therapy) to 2000 ng/ml for C12.

Liver fibrosis (LF) must be assessed before talking treatment decisions in hepatitis B. In Burkina Faso, liver biopsy (LB) remains the "gold standard" method for this purpose. Access to treatment might be simpler if reliable alternative techniques for LF evaluation were available. The hepatitis B virus (HBV)-infected patients who underwent LB was invited to have liver stiffness measurement (Fibroscan) and serum marker assays. Fifty-nine patients were enrolled. The performance of each technique for distinguishing F0F1 from F2F3F4 was compared. The area under receiver operating characteristic (AUROC) curves was 0.61, 0.71, 0.79, 0.82, and 0.87 for the aspartate transaminase to platelet ratio index (APRI), Fib-4, Fibrotest, Fibrometre, and Fibroscan. Elastometric thresholds were identified for significant fibrosis and cirrhosis. Combined use of Fibroscan and a serum marker could avoid 80% of biopsies. This study shows that the results of alternative methods concord with those of histology in HBV-infected patients in Burkina Faso. These alternative techniques could help physicians to identify patients requiring treatment.

Chagas disease (CD) is endemic to Latin America; its prevalence is highest in Bolivia. CD is sometimes seen in the United States and Canada among migrants from Latin America, whereas it is rare in Europe. We report 9 cases of imported CD in France from 2004 to 2006.

In HIV/hepatitis C virus (HCV)-coinfected patients, it is recommended to repeat liver biopsy every 3 years when anti-HCV treatment is not indicated. We studied fibrosis progression in HIV/HCV-coinfected patients, who were not receiving anti-HCV treatment, on the basis of two successive liver biopsies. Thirty-two patients were retrospectively included. Twenty-six patients (79%) were on antiretroviral treatment at the first biopsy. The mean CD4 cell count was 470 +/- 283/mm(3). Three patients were staged F2 and the remainder F0/F1. The median interval between the two biopsies was 49 (24-80) months. At the second biopsy, the stage distribution was F0 0%, F1 41% (n = 13), F2 34% (n = 11), F3 19% (n = 6) and F4 6% (n = 2). The mean fibrosis progression rate (FPR) was 0.25 points/year. Nine patients (28%) were considered as rapid fibrosis progressors (progression by more than two points) and their FPR was 0.5 point/year; comparison of these subjects with the other 23 patients showed no relation between FPR and age, alcohol consumption, CD4+ cell count, HIV viral load, HCV genotype, aspartate aminotransferase or alanine aminotransferase. Analysis of the treatment received between the two liver biopsies did not find any correlation between liver FPR and a specific compound. Fifteen patients started anti-HCV therapy based on the second biopsy. Liver fibrosis in HIV/HCV-coinfected patients should be evaluated at least every 3 years, as nine of 32 (28%) of our patients progressed by at least two fibrosis points despite a high CD4+ cell count. The second biopsy showed that 15 patients (45%) qualified for anti-HCV therapy. Development of noninvasive methods of fibrosis evaluation should permit more frequent monitoring.

Haematological anomalies are frequent during HIV infection, and can be the fact of virus and or bone marrow toxicity of antiretroviral drugs. In order to analyze the evolution of the haematological parameters during HAART this work was carried out in the internal medicine department of the national teaching hospital Yalgado-Ouédraogo in Ouagadougou. So 107 patients receiving for the first time HAART and followed regularly were retained. The immunological efficacy at the end of the first six months was 60, 75% with an average gain of 119 CD4/mm3. The haematological changes at the end of these first six months showed: --an anaemia in 51.4% of the cases at month 6 versus 80.3% at baseline (p=0.0001). The average rate of haemoglobin was 11.8 versus 11.2 g/dl at baseline in the AZT containing HAART regimen (p=0.014) and 12.2 versus 10.7 g/dl at baseline in the group without AZT (p=0.00006). --a neutropenia in 35.5% of the cases at month 6 versus 31.7% at baseline (p=0.6). The average rate of neutrophil was 1908/mm3 versus 2267.1/mm3 at baseline in the AZT containing HAART regimen and 2150.7/mm3 versus 2001.9/mm3 at baseline in the group without AZT These results show that the therapeutic efficacy measured on the immunological answer is accompanied by a reduction of haematological anomalies. They also suggest the necessity to evaluate the cotrimoxazole impact before deciding the interruption of AZT.

HIV-infected patients who are on hemodialysis have a worse prognosis than noninfected patients who are on hemodialysis. Their outcome in the highly active antiretroviral therapy (HAART) era remains unclear. Outcomes in patients who were enrolled in the French Dialysis in HIV/AIDS (DIVA) cohort were determined in a 2-yr prospective follow-up. All HIV-infected patients who were on hemodialysis in France on January 1, 2002, were included and followed prospectively until January 1, 2004. Patients' survival was examined by Kaplan-Meier method, and mortality risk factors were examined using uni- and multicovariate analyses. Survival was compared with that of 584 hemodialysis patients who did not have HIV or diabetes and were enrolled in the French Dialysis Outcomes and Practice Patterns Study II (DOPPS II) in the same period (after standardization for the average age, gender, and ethnicity of the DIVA cohort). A total of 27,577 patients were receiving hemodialysis in France at the beginning of the study; 164 (0.59%) were infected with HIV, 72% were male, mean age was 44.8 +/- 10.9 yr, and 65% were black. The 2-yr survival rate was 89 +/- 2% and statistically indistinguishable from the survival of the French cohort extracted from the DOPPS II study. Significant mortality risk factors were low CD4 cell count (hazard ratio [HR] 1.4/100 CD4 cells per mm(3) lower), high viral load (HR 2.5/1 Log per ml), absence of HAART (HR 2.7), and a history of opportunistic infection (HR 3.7), the last two being independent (HR 2.6 and 3.6, respectively). Survival of HIV-infected patients who are hemodialysis has greatly improved. A prospective cohort of paired hemodialysis patients with and without HIV is required to compare better their mortality in the HAART era.

Background: A 30-year-old HIV-infected woman presented with fever and abdominal pain 4 days after initiation of highly active antiretroviral therapy (HAART), and 1 month after initiation of antimicrobial therapy for Mycobacterium tuberculosis infection. A diagnosis of immune restoration inflammatory syndrome (IRIS) was considered, and corticosteroids were started. Steroid therapy doses were progressively tapered, during which time the patient developed renal failure with enlarged kidneys. A renal biopsy showed acute interstitial nephritis. Extensive investigations failed to detect active infection. The efficacy of HAART was attested by increased CD4+ cell counts and undetectable viral replication., Investigations: Physical examination, plasma viral load and CD4+ cell count, abdominal and renal ultrasound, renal and peritoneal biopsies, renal and liver function, chest X-ray, and bronchoalveolar lavage culture., Diagnosis: Acute renal failure secondary to IRIS., Management: Prednisone therapy.

A review of the hospital charts for 788 patients treated in 19 public and private clinics in Cameroon showed that clinical follow-up visits, biologic follow-up visits, and drug supply were irregular and that many patients interrupted treatment. Virological and immunologic effectiveness of therapy was as expected in patients for whom results were available.

Background: In 1997, 0.38% of dialysis patients in France were infected by human immunodeficiency virus (HIV). No prevalence data were available in France since the widespread introduction of highly active antiretroviral therapy., Methods: This was a cross-sectional epidemiologic survey. A questionnaire was sent to all French dialysis centers in July 2002. The centers that did not respond were sent 3 additional mailing reminders. Finally, the nonresponding centers were called early in 2004., Results: Of the 27,577 patients on hemodialysis and 587 patients on peritoneal dialysis, 190 patients (0.67%) were infected by HIV. HIV-associated nephropathy was the cause of renal failure in 39.8% patients. Mean age was 44.6 +/- 10.9 years, the mean duration of dialysis was 4.9 +/- 5.9 years, the mean known duration of HIV infection was 8.9 +/- 5.6 years. Eighty-two percent of patients received antiretroviral therapy (ART). Fifty-eight percent of ART-treated patients had an undetectable HIV plasma viral load with a median CD4+ T-cell count 303/mm(3)., Conclusion: The prevalence of HIV infection among French dialysis patients was 0.67% in late 2002, a 79% increase since 1997. Possible reasons for this large increase include increased access to dialysis, better general status of HIV dialysis patients, and increasing proportion of patients originating from Africa and the Caribbean. The current efficacy of ART makes renal transplantation a realistic option for these young patients.

Malaria is the most frequent cause of fever among travellers returning from tropical countries. Each year about 7000 cases are notified in France, of which 90% are due to Plasmodium falciparum. We describe the case of a Caucasian female patient with no previous exposure to malaria in whom splenic infarction occurred during effective antimalarial treatment for initially uncomplicated acute malaria. Management was restricted to close clinical monitoring and analgesia (subcutaneous morphine). Imaging abnormalities resolved within a few months. We found seven other such cases in the literature. All seven patients were younger and splenic infarction occurred later than in the case we describe. Clinical outcome was favourable in all the cases. It is noteworthy that this rare complication can occur despite appropriate antimalarial prophylaxis and treatment. There are no known predictive signs. Clinicians must be aware that left hypochondrial pain occurring during treatment for acute malaria may be due to splenic infarction.

Introduction: The diagnostic approach when confronted with a pseudo-tumoral lesion and fever is difficult since it evokes an infectious, rheumatismal inflammatory or even systemic disease., Observation: A 39 year-old Vietnamese man was hospitalised for polyarthralgia if the arm and fever (39 degrees C). He was treated with non-steroidal anti-inflammatories, which were only partially effective. Biological examinations revealed a severe inflammatory syndrome and cytolysis three-fold higher than normal. Since the infectious, rheumatismal and immunological explorations were negative and in view of the appearance of a pseudo-tumoral inflammatory lesion of the left arm concomitant to infiltration of the underlying muscle revealed on MRI, a muscle biopsy was performed showing eosinophilic fasciitis. Diagnosis of Shulman's syndrome was made and the affection rapidly improved with corticosteroids., Comments: The presentation of our patient was atypical for several reasons: his Vietnamese origin, the initial fever peak at 39 degrees C, the unilateral involvement, the severe inflammatory syndrome, the initial absence of hypereosinophilia, the visceral involvement and notably myositis are all uncommon in Shulman's syndrome. Hence, it is important to rule out its differential diagnosis from local edematous scleroderma, which does not share the same prognosis.

Ritonavir (RTV) strongly increases the concentrations of protease inhibitors (PIs) in plasma in patients given a combination of RTV and another PI. This pharmacological interaction is complex and poorly characterized and shows marked inter- and intraindividual variations. In addition, RTV interacts differently with saquinavir (SQV), indinavir (IDV), amprenavir (APV), and lopinavir (LPV). In this retrospective study on 542 human immunodeficiency virus-infected patients, we compared inter- and intraindividual variability of plasma PI concentrations and correlations between the C(min) (minimum concentration of drug in plasma) values for RTV and the coadministered PI C(min) values. Mean RTV C(min)s are significantly lower in patients receiving combinations containing APV or LPV than in combinations with SQV or IDV. With the most common PI dose regimens (600 mg of IDV twice a day [BID], 800 mg of SQV BID, and 400 mg of LPV BID), the interindividual C(min) variability of patients treated with a PI and RTV seemed to be lower with APV and LPV than with IDV and SQV. As regards intraindividual variability, APV also differed from the other PIs, exhibiting lower C(min) variability than with the other combinations. Significant positive correlations between RTV C(min) and boosted PI C(min) were observed with IDV, SQV, and LPV, but not with APV. Individual dose adjustments must take into account the specificity the pharmacological interaction of each RTV/PI combination and the large inter- and intraindividual variability of plasma PI levels to avoid suboptimal plasma drug concentrations which may lead to treatment failure and too high concentrations which may induce toxicity and therefore reduce patient compliance.

CHARACTERISTIC FEATURES: Piercing, an act that modifies the body, has progressed considerably in France over the last few years. The population involved has grown and become more diversified. Performed with a solid needle or a catheter, a wide variety of anatomic localizations are concerned, particularly the nose, ears, and navel. The shape of the "rings", generally made of surgical steel, niobium or titanium, varies greatly. Wound healing by epithelialisation can take up to several months. INFECTIOUS RISK: Between 10% and 20% of all piercings lead to a local infection. The most commonly found causal agests are Staphylococcus aureus, group A Streptococcus and Pseudomonas sp. These germs can cause severe life-threatening complications even in common localizations (earlobe). Viral transmission is another risk (hepatitis B, hepatitis C, hepatitis delta, HIV). A few cases of fatal fulminant hepatitis have been described immediately after piercing. SAFETY MEASURES: Generally performed under less than desirable sanitary conditions, safety measures are needed for piercing. Among professional "piercers", a certain number have emphasized the need for providing their clients with safer services. The prevention of infection risk should be a priority for all. Work along this line has been done in the United States and Canada. In light of the impact on public health, it is important to rapidly develop guidelines and regulations for piercing in France. Both professional piercers and health care workers should participate in developing these safety measures in order to assure their implementation.

Objectives: (1) To determine the incidence and outcome of Pseudomonas aeruginosa infection in HIV-infected patients. (2) To study the antimicrobial susceptibility of P. aeruginosa isolates in this particular population. (3) To identify risk factors for these infections., Patients and Methods: A retrospective case-control study performed in a 28-bed infectious-diseases unit in a 940-bed university hospital. All cases were defined as HIV-infected patients with severe infections due to P. aeruginosa, including bacteremia, lower or upper respiratory tract infections, infections related to a central venous catheter, and cutaneous/muscular infection. Each case was matched with an HIV-seropositive control not infected by P. aeruginosa and hospitalized on the same dates as the cases., Results: One thousand and thirty-five HIV-infected patients were hospitalized during the study period. A first severe P. aeruginosa infection was documented in 41 patients, giving an overall annual incidence note of 2.51 episodes per 100 admissions. Forty of the 41 case notes were available for analysis. They consisted of 17 cases of bacteraemia, four upper respiratory tract infections, 10 lower respiratory tract infections, three catheter-related infections, and six cutaneous/muscular infections. Of these 40 cases, 60% were nosocomial and the remainder were community-acquired. The overall mortality rate was 22% (47% in bacteraemic forms). Twenty five percent of patients relapsed after an average of 37 days. The case-control comparison showed that AIDS was more frequent among the cases (92% vs. 74%, P = 0.04), who also had a lower PN count (P = 0.005), and a lower CD4 cell count (15.7 +/- 18.8/mm3 vs. 118 +/- 211/mm3; P = 0.0007). The number of days spent in hospital in the previous 3 months (29.3 +/- 20.7 vs. 19.7 +/- 14, P = 0.04) was significantly higher among the cases. In a multivariate analysis, examining treatments received in the previous month, only co-trimoxazole [OR = 5.5 (1.1-26.9)], penicillins [OR = 5.2 (1.1-25.3)], steroids [OR = 5.5, (1.2-25.5)] and a CD4 cell count below 50/mm3 [OR = 13.2 (1.4-129.4)] were identified as risk factors., Conclusion: P. aeruginosa infection is a not frequent bacterial disease in highly immunodeficient HIV-infected patients. It is frequently fatal and must be borne in mind in the advanced stages of HIV disease, especially when patients have received co-trimoxazole (trianthoprim-sulphamethoxazole), penicillins or steroids.

Background: Paragonimiasis, caused by a lung fluke, is an parasitic disease rarely encountered in France., Case Report: A 52-year-old man developed dyspnea, cough, mild fever and chest pain. Pleural effusion suggested possible pulmonary embolism or tuberculosis. Cell counts in blood and pleural effusion fluid revealed major eosinophila in this patient who had recently returned from a trip to Japan. Paragonimiasis was confirmed by ELISA. Treatment with praziquantel led to complete clinical and radiographic recovery., Discussion: The clinical and radiographic features of paragonimiasis are often similar to tuberculosis with pleuropneumopathy, mild fever and dyspnea. ELISA has now replaced parasitologic diagnosis. Cure is achieved with praziquantel.

A prospective cohort study on the mother-to-child transmission of human immunodeficiency virus type 1 (HIV1), type 2 (HIV2) and dual positivity (HIV1 + HIV2) was carried out in Banfora, West Burkina Faso. The study samples consist of 117 newborns of HIV-seropositive women matched to 234 newborns of HIV-seronegative women. Among cases, 91 were born of HIV1-seropositive mothers, 15 were born of HIV2-seropositive mothers and 11 were born of HIV1 and HIV2 dual-seropositive mothers and were included in an 18-month follow-up. Calculation of the mother-to-child transmission rate was according to the recommendations of the European Economic Community working group. The HIV1 mother-to-child transmission rate was estimated to be 27.8% (95% confidence interval (CI) 24.5 to 32.4) with one method and 25.5% (95% CI 13.5 to 37.5) with a second method. For HIV2, this rate was estimated to be 29.5% (95% CI 26.0 to 39.8) and was not statistically different from the HIV1 mother-to-child transmission rate. No case of transmission was observed in children born of dual seropositive mothers. Survival rate at month 18 was significantly lower for children born of HIV1 mothers: 83.7% (95% CI 78.2 to 92.2). Survival rates were similar between children born of HIV2-seropositive (86.7), dual HIV1 + 2-positive (100) and seronegative mothers (92.0%). Findings suggest a higher mother-to-child transmission rate of HIV2 in children born in Burkina Faso than in Europe and a low clinical expression of HIV2 in children.

The obstetrical referral patients admitted to the Sanon Souro hospital in Bobo-Dioulasso (Burkina Faso) during 1991 were retrospectively reviewed. During the study period 741 women were admitted. The median distance between the referring centre and Bobo-Dioulasso was 33 km. Median age was 22 years and median parity was 3. Indications for referral were dominated by obstructed labour, haemorrhages and infections. The proportion of maternal mortality in the study was 5.4% and was not related to maternal age or parity. However, there was a linear trend of increasing mortality according to the distance between the referring centre and Bobo-Dioulasso (X2 for trend: 7.56; p = 0.006). The perinatal mortality rate of 420 p. thousand was not related to maternal age, but a parity exceeding 4 was a risk factor for the occurrence of perinatal death (relative risk: 1.4; 95% C.I.: 1.2-1.7). As for maternal mortality, there was a linear increase of perinatal mortality with the distance from the referring centre (X2: 20.8; p = 0.00001). There was no marked seasonal variation in the number of referrals nor in the mortality rates per month.

The authors report a case of polyarteritis nodosa which coincide with serological conversion to parvovirus B19. After review of the literature, they recall the role of this virus in human pathology and also the role of different infectious agents in the PAN pathogenesis.
