[Should there be a specific management for HIV infected-immigrants in France?]. / Faut-il une prise en charge spécifique des migrants infectés par le VIH en France?

Immigrants living in France account for one third of new cases of infection and are a target population for prevention. Care givers should adapt their management practice, taking into account this population's specificities which are not restricted to cultural differences but include major socioeconomic factors. In addition to training on alien rights and basic sociocultural knowledge, care-givers (especially clinicians) must spend more time with the patient (especially at the beginning of the relationship) and accept sharing the "medical power" with other people with a better knowledge of other aspects of the patients' life in addition to the medical one. As in other chronic diseases, mediation is one of the available tools with evident benefits for any patient. Assuming compliance is the same for migrants as for other patients, using this mediation will warrant therapeutic success.

Oral contraception and unprotected sex with occasional partners of women HIV-infected through injection drug use.

Among HIV-infected women, unprotected sex with the main sexual partner is common practice. Conversely, studies about condom use with sexual partners of unknown HIV sero-status are sparsely reported. We aimed to assess the impact of oral contraception on unsafe sexual behaviours with occasional partners in women HIV-infected through injection drug use. The analysis focused on 90 women, enrolled in the French cohort MANIF 2000 and reported having engaged in sexual relationships with occasional partners during a 48-month period. Visits where women reported unprotected sex with occasional partners in the prior 6 months were compared to visits where they reported protected sex using a logistic model based on Generalised Estimating Equations. Unprotected sex with occasional partners was independently associated with oral contraception (OR[95%CI] = 3.2[1.4-7.2]), reporting only one occasional partner (OR[95%CI] = 3.1[1.6-6.2]) and antiretroviral treatment receipt. No significant association was found between unprotected sex and CD4 level or plasma viral load. With the growing population of people living with HIV as a chronic infection, the development and evaluation of HIV-prevention interventions tailored toward women remain a public health priority. Risk reduction counselling and interventions are needed to promote either the use of dual contraception or, alternatively, that of female condom.

[Peritoneal tuberculosis: 27 cases in the suburbs of northeastern Paris]. / Tuberculose péritonéale: 27 cas dans la banlieue nord-est de Paris.

SETTING: Peritoneal tuberculosis did not disappear from France during the 1990s. OBJECTIVE: To determine the characteristics of peritoneal tuberculosis in the north-eastern suburbs of Paris. METHOD: A retrospective study of cases diagnosed with peritoneal tuberculosis between 1990 and 1998 in five suburban hospitals in the north-east region of Paris. RESULTS: Twenty-seven cases of adult peritoneal tuberculosis were diagnosed. There were nine women and 18 men, with a mean age of 37.5 years, 88.9% of whom were foreign born. General and digestive symptoms--abdominal pain and/or ascites--were present in 96.3% of the cases. The mean delay in treatment was 30 days. Peritoneal involvement was isolated in 25.9% of cases, and associated with pulmonary tuberculosis in 40.7% or hepatic tuberculosis in 25.9%. Co-infection with HIV (human immunodeficiency virus) was present 14.8% of cases. Culture of ascites fluid, laparoscopy and/or laparotomy (n = 17), with directed biopsy, aided in the formal diagnosis of peritoneal tuberculosis in 59.2%. One relapse and one case of multiresistance were observed. The mean duration of treatment was 9 months (range 6-12 months). Three patients received treatment with corticosteroids, and 91.2% of the patients achieved cure without sequelae. CONCLUSION: Peritoneal tuberculosis is not rare in the Paris region. The diagnosis should be suspected in case with ascites and fever, and can be confirmed by laparoscopy with sampling for bacteriology and histology. The methods of treatment need to be standardised.

Mycobacterium kansasii septic arthritis: French retrospective study of 5 years and review.

Septic arthritis due to Mycobacterium kansasii is rare; only 40 cases have been published. A French national inquiry revealed the occurrence of 10 new cases between 1992 and 1997 (8 men and 2 women: mean age, 37 years; range, 25-54 years). Seven had an underlying condition: AIDS (n=4), chronic skin psoriasis and AIDS (n=2), or a renal transplant (n=1). Trauma to the joint, use of intra-articular corticosteroid(s) 1 month to 2 years after the event, and chronic skin psoriasis were risk factors. The mean interval between appearance of the first symptoms of arthritis and the diagnosis was 5 months. Monarthritis was localized to the knee (n=4), wrist (n=3), finger (n=1), elbow (n=1), or ankle (n=1). The main diagnostic procedure was culture of a synovial biopsy specimen. In all cases, debridement was associated with antimycobacterial treatment. Three patients died of AIDS during treatment, and another is still undergoing treatment; the other 6 patients were cured. M. kansasii infection should be considered in all cases of indolent arthritis with any of the following risk factors: local trauma, local or systemic corticosteroid therapy, chronic skin psoriasis, and immunodepression, especially that due to human immunodeficiency virus infection.

Impact of protease inhibitors on AIDS-defining events and hospitalizations in 10 French AIDS reference centres. Fédération National des Centres de Lutte contre le SIDA.

OBJECTIVE: To assess the clinical and economic consequences of the use of protease inhibitors in the treatment of HIV infection. DESIGN: Multicentric, observational, retrospective cohort study. SETTING: Ten AIDS reference centres in France. PATIENTS: All patients followed in each centre from September 1995 through October 1996. MAIN OUTCOME MEASURES: AIDS-defining events, death, health-care resources use, administration of antiretroviral therapy. RESULTS: Data from 7749 patients in 10 centres showed a drop in hospitalization days by 35%, new AIDS cases by 35%, and deaths by 46%. In the same period, the proportion of patients receiving antiretrovirals rose from 36 to 53% including highly active antiretroviral therapy (HAART), which rose from 0.3 to 18%. Overall cost evaluation showed a slight increase of monthly treatment cost of US$ 12 per patient. Comparison of the three centres that used HAART earliest to the three centres that used it latest showed a clear benefit to early HAART with a drop in hospitalization days by 41%, new AIDS cases by 41% and deaths by 69%. The proportion of patients with HAART rose to 27% and monthly health-care cost decreased by US$ 248852 (i.e., by US$ 101 per patient per month). Late prescribing centres experienced a less marked effect with a drop in hospitalization days by 22%, new AIDS cases by 31%, and deaths by 32.5%. Proportion of patients with HAART rose to 12% and monthly health-care costs increased by US$ 113578 (i.e., by US$ 38 per patient per month). CONCLUSIONS: This study supports the extensive use of HAART in HIV-infected patients.

Amphotericin B in a lipid emulsion for the treatment of cryptococcal meningitis in AIDS patients.

We determined the safety and efficacy of deoxycholate-amphotericin B (d-AmB) mixed with Intralipid (IL) as the initial treatment of AIDS-associated cryptococcal meningitis in a phase II, multicentre, non-comparative open study, assessing two dosages of ILd-AmB: 1 mg/kg (group A, n = 9) and 1.5 mg/kg (group B, n = 6). Patients were treated daily for 2 weeks, then three times weekly for 4 weeks. The ILd-AmB dosage was decreased due to toxicity in three patients in each group. Serum creatinine increased significantly on day 14 in group A and on day 7 in group B. Nephrotoxicity, (serum creatinine level > 165 mumol/L) was noted in two and five patients in groups A and B, respectively. Nine adverse haematological events were noted (seven cases of anaemia requiring transfusion, and two cases of neutropenia < 750/mm). Two patients had an increase in serum alkaline phosphatase. In each cohort, 15% of the infusions were associated with fever and/or chills. Successful outcome was obtained in half of the patients. We conclude that, in AIDS patients with cryptococcosis, tolerance to ILd-AmB was acceptable when the daily dosage did not exceed 1 mg/kg, but the higher 1.5 mg/kg daily dosage was associated with an unacceptable rate of nephrotoxicity. Neither of these relatively high daily dosages of ILd-AmB achieved an improved rate of successful outcomes compared with lower daily dosages of conventional d-AmB in glucose.

OKT4 epitope deficiency in patients infected with the human immunodeficiency virus: a cause of underestimation of the CD4 lymphocyte count.

Two black patients who were infected with the human immunodeficiency virus (HIV) and who had hereditary deficiency of OKT4 epitope were investigated. The patients' lymphocytes lacked the OKT4 surface antigen but reacted with other monoclonal antibodies recognizing the CD4+ helper-inducer T lymphocytes. The CD4 lymphocyte count is a surrogate marker for clinical progression of HIV disease, but it could be unreliable in regard to patients with partial or complete OKT4 epitope deficiency.

[Chronic refractory pain in cancer patients. Value of the spinal injection of lysine acetylsalicylate. 60 cases]. / Douleur chronique rebelle des cancéreux. Intérêt de l'injection intrarachidienne d'acétylsalicylate de lysine. Soixante observations.

Several animal studies have demonstrated that pain is modulated by spinal mechanisms involving prostaglandins and that acetylsalicylic acid (ASA) administered intrathecally has an analgesic effect. We report our experience of this treatment in 60 patients with proven and advanced cancer. An isobaric solution of lysine acetylsalicylate was administered by lumbar puncture in doses ranging from 120 to 720 mg of ASA. The results were evaluated using the habitual criteria: scoring system, behaviour, consumption of analgesic drugs. In this trial the method proved astonishingly effective (78% of the cases). Analgesia was strong, almost immediate and without influence on motricity. No thermic or neurovegetative changes were noted. The effect of one injection lasted from 3 weeks to 1 month on average; it was reproduced and often more prolonged after a repeat injection. Pain associated with bone metastases seems to constitute the best indication, notably in breast and lung cancer and in myeloma. Visceral (pancreas) or neural pain requires higher doses to respond. Failures (22%) were due to such factors as insufficient dosage at the very beginning of our experience or severe depressive syndrome. The perineal and sphincteral pain of rectal cancer often resists treatment. This simple, inexpensive and very effective method with no other complication than a frequent tendency to fatigue should rank among other analgesic measures in cancer. The lack of respiratory depression is a major advantage over catheter spinal opiate analgesia. We consider that its main indications are pain associated with osteolytic metastases of adenocarcinomas, and myelomas. Owing to the absence of formal toxicological data, its use must be limited to cancer pain and to patients with a life expectancy of less than 2 years.

[The Duffy blood group in migrants of French-speaking Africa]. / Le groupe sanguin Duffy chez les migrants d'Afrique francophone.

The Duffy blood types survey in 544 subjects coming from French speaking African countries, shows the high percentage of subjects having a Duffy a- b- blood type (94%). It ought to be emphasized that this predominantly Duffy a- b- population resides in areas in where there is according to the WHO data, a very low incidence of Plasmodium vivax invasion. Moreover, we have taken for another example North Vietnam, an area where there is a large Plasmodium vivax invasion and where we have found a small percentage of Duffy negative subjects (5.6%). In agreement with many authors reporting an association between Duffy negatively and vivax malarial refractoriness, this survey demonstrate that in French speaking African areas where there is a very low incidence of Plasmodium vivax invasion we have found, as expected, a high rate of Duffy negative subject.

[Bone scintigraphy and diagnosis of osteoarticular tuberculosis in migrant workers. Study of a series of 50 scintigraphies]. / La scintigraphie osseuse et le diagnostic de la tuberculose ostéo-articulaire du transplanté: Etude d'une série de 50 scintigraphies.

Bone scintigraphy with 99 m technetium labelled phosphorus compounds was achieved in 50 west Africans migrant workers in Paris. Bone and joint tuberculosis was assumed in 20 cases. In 5 of these 20 cases, bone scan, but not X-Ray, showed abnormalities, and in 4, bone scan disclosed more localisations than X-Rays. In 7 cases, yet, bone scan was normal, with major osteolytic X-Rays lesions in 3 cases, minor in 2 cases, and isolated cold abscesses in two more cases: these means 7 false-negative results. Among the 30 other cases, 29 were considered as mechanical vertebral pathology, and 1 sacro-iliitis Brucellosis. Bone scan was normal in 28 cases the 2 others are unexplained false-positive. Although non-specific and not completely reliable, we think that bone-scanning is useful in bone-tuberculosis check-up, especially to obtain early diagnosis and detect multifocal localisations.
