Reduced maternal mortality in Tunisia and voluntary commitment to gender-related concerns.

OBJECTIVE: To estimate the number and causes of maternal deaths in Tunisia from 1999 to 2007, and compare the results with the last report (1993-1994). METHODS: Data on all deaths of women of reproductive age in the public (1999-2007) and private (2006 only) health sectors were collected and assessed for whether the death was due to pregnancy. Number of live births was provided by the National Institute of Statistics. RESULTS: Mean maternal mortality ratio (MMR) in Tunisia decreased from 68.9 per 100000 live births in 1993-1994 to 36.3 (95% confidence interval, 27.9-46.5) in 2005-2007 (P<0.001). Causes of maternal death did not change significantly during the study period (1999-2007): hemorrhage and hypertensive disorders were the main causes. The gap between urbanized and more rural regions observed in 1993-1994 had narrowed, although MMR remained higher in central and western regions than on the east coast. CONCLUSION: The improvement in MMR can be credited to the voluntary political commitment focused on gender-related concerns that has been made in Tunisia, including access to family planning; legalization of abortion; and creation of the National Board for Family and Population, and the Tunisian Safe Motherhood initiative in 1999.

[Evaluating the therapeutic care of HIV infection in Tunisia]. / Evaluation de la prise en charge thérapeutique de l'infection par le VIH en Tunisie.

OBJECTIVE: Our aim is to determine different therapeutic response profiles in Tunisian HIV-1 infected patients, to identify those with therapeutic failure and to compare the results of the genotypic resistance test used in Tunisia (INNO LiPA Test) with those of automatic sequencing to evaluate its efficacy. METHODS: The retrospective survey concerns 392 infected patients enrolled from January 2001 to December 2006. Evaluation of HIV INNO LiPA test was performed by comparing these test results with those of automatic sequencing in 36 plasmatic samples for 13 infected patients with therapeutic failure. RESULTS: on the basis of the HIV viral load evolution, 57.55% of patients present a good therapeutic response and 42.44% a bad one. Patients with therapeutic failure require genotypic resistance test. A comparison of HIV INNO LiPA test and direct sequencing showed a strong concordance between the two tests results either for reverse transcriptase gene or protease gene. However, the results obtained by INNO LiPA test (8.79% of analysed codons ) and the limited number of analysed codons were the defaults of INNO LiPA technique. CONCLUSION: the contribution of INNO LiPA technique in the knowledge of the epidemiological HIV resistance profiles of virus strains of HIV infected individuals failing therapy was considerable. However, due to INNO LiPA technique limitations, sequence analysis must be considered a more complete assay for the monitoring of antiretroviral resistance of HIV infected patients.

[Virological diagnosis and follow-up of HIV infection. State of the art and situation in Tunisia]. / Diagnostic et suivi virologique de l'infection par le VIH : etat actuel et situation en Tunisie.

Human immunodeficiency virus (HIV) is a retrovirus infecting approximatively 40 million people worldwide. HIV is characterized by a great variability with epidemiological, diagnostic and therapeutic implications. The course of infection goes through three stages (acute infection, clinical latency and AIDS) with the evolution of virological markers (anti-HIV antibodies, p24 antigenemia, plasma RNA and proviral DNA). Direct virological diagnosis is mainly based on molecular tools allowing viral genome detection and amplification with specific primers and nucleic probes besides p24 antigenemia detection, and more rarely viral culture. Antigenic properties of viral proteins elicit in infected patients antibody synthesis, which is detected using serology (ELISA and Western blot tests). The follow-up of infected patients is carried out with plasma HIV-1 RNA quantitation and phenotypic or genotypic characterization of variant isolates. Virological tests are prescribed according to clinical presentation (screening, acute infection, newborn from HIV-infected mother). Most of these virological tools are available in Tunisia, allowing both diagnosis of HIV infection and monitoring of infected individuals. Regarding diagnostic tests indication and interpretation, multidisciplinary concertation is hopeful in order to optimize patient management.

[Effect of triple antiretroviral therapy on Tunisian AIDS profile: study of 139 cases]. / Impact de la trithérapie anti-retrovirale sur le profil evolutif du sideen Tunisien: etude de 139 cas.

We report a retrospective study to estimate highly active antiretroviral therapy (HAART) effect in 139 HIV infected patients. Four criteria are studied: prevalence of opportunistic infections, CD4 cell count evolution, viral load progression and mortality. Gastrointestinal side effects are the most common clinical adverse reaction (61.1 percent), and hematological side effects are the most common biological adverse reaction (61.2 percent). During the 22.8 months (3 months to 6 years) follow-up average period, CD4 cell counts remained above 500 per cubic millimeter in only 25.8 percent of cases, while 63.5 percent of patients had a viral load below 400 copies per milliliter. During the study on patients receiving HAART, opportunistic infections appeared in 17.3 percent of cases (24 cases) and mortality in 6.4 percent of cases.
