&NA; The objective of this study was to describe the epidemiology, clinical presentation and consequences of chronic daily headache (CDH) in France. A representative nation‐wide sample of the general population was identified using a stratified sampling method. Ten thousand five hundred and eight‐five subjects were screened in face‐to‐face interviews, and data collected using a standard questionnaire. An overall point prevalence of CDH in the general population of 2.98% was observed. Two‐thirds of these subjects presented migraine‐like features. Severity, functional impact and healthcare consumption were higher than in subjects reporting episodic migraine in the same sample. Of the subjects, 28.2% reported the most severe migraine disability assessment scores (Grades 3 and 4), compared to 12% of episodic migraineurs. A qualité de vie et migraine score of 68.4 was observed, indicating severely attenuated quality of life. Only 6.6% of subjects were taking prophylactic treatment, whilst 88% were using non‐specific acute headache treatments. The frequency of physician consultations and laboratory examinations was significantly higher than in individuals with episodic headache. CDH is thus a relatively prevalent condition in the general French population, associated with an important burden of suffering and with considerable expenditure in the health service. Management of this condition is generally inappropriate.

There have been many epidemiological studies of chickenpox but only a few of herpes zoster. We report data from an observational study, conducted in France during a 1-year period, of 9038 patients who presented with acute herpes zoster (n = 8103) or postherpetic neuralgia (PHN; n = 935) at the office practices of 4635 general practitioners or dermatologists. The incidence of herpes zoster in France was found to be similar to that in the literature: from 1.4 to 4.8 cases per 1000 population per year. The patient profiles and clinical patterns were delineated, as well as the management decisions made according to the type of treating physician. The impact of herpes zoster on quality of life was evaluated on the basis of the Medical Outcome Study Short Form 36 (MOS SF 36) scale, which is widely used for assessing quality of life in the field of health. This study provides reference data on the substantial deterioration in quality of life associated with herpes zoster and PHN.

OBJECTIVES:The noninvasive serum markers, FibroTest–ActiTest (FT–AT), are an alternative to liver biopsy in patients with chronic hepatitis C and B. The aim was to use these markers in a prospective study of patients treated with lamivudine in order to assess the impact of treatment, as well as the factors associated with fibrosis progression.METHODS:Two hundred and ninety-eight patients were included in a prospective longitudinal study in 50 hospitals across France. FT–AT were measured at baseline, and then after 6, 12, and 24 months of lamivudine 100-mg treatment. Epidemiological, clinical, and virologic characteristics were analyzed by univariate and multivariate analysis.RESULTS:Two hundred and eighty-three patients were included for analysis. The accuracy of FT–AT versus biopsy was validated with the area under the ROC curve, 0.77 (SE = 0.03) for bridging fibrosis and 0.75 (SE = 0.06) for severe activity (A3). At baseline, bridging fibrosis (METAVIR stages F2–F3–F4) was highly associated (p < 0.001) in multivariate analysis with male gender and age and marginally associated with anti-HBe presence (p= 0.05) and non-Asian ethnic origin (p= 0.046). Lamivudine treatment had a very significant impact overall. FT decreased significantly from 0.51 at baseline to 0.37 at 24 months (p < 0.001), and 85% of patients had improvement at 24 months. AT also decreased significantly from 0.56 to 0.13 (p < 0.0001), and 91% of patients had improvement at 24 months. A three-phase kinetics was observed for both fibrosis and activity; there was a marked improvement during the first 6 months, followed by a plateau between 6 and 12 months, and another improvement between 12 and 24 months. The occurrence of a YMDD variant does not entirely explain these three-phase variations. The first phase impact on fibrosis rates was higher in Asian patients (p= 0.01) and in patients younger than 40 yr (p < 0.001).CONCLUSIONS:In patients with chronic hepatitis B, a 24-month course of lamivudine treatment leads to a significant decrease in necroinflammatory grades and fibrosis stages as assessed by noninvasive markers, with the occurrence of a three-phase kinetics. FT–AT should be useful in the noninvasive follow-up of lamivudine treatment.

AIMS To assess the impact of irritable bowel syndrome (IBS) on patient-reported health-related quality of life (HRQOL). METHODS Two HRQOL instruments were administered by telephone interviews to a sample of 253 IBS French patients recruited from the general population. IBS was diagnosed according to the Manning, Rome I and Rome II criteria. Patients with organic diseases were excluded from the study. A generic instrument, the Short Form 36 (SF-36), and an IBS disease-specific instrument, the IBSQOL, were used. RESULTS Patients with IBS had statistically significant (P<0.05) lower scores for all SF-36 QOL domains compared with the general French population. Women (N=192) reported significantly (P<0.05) poorer HRQOL on both the SF-36 and the IBSQOL scores than men (N=61) for all domains except energy on the SF36 and the sleep on the IBSQOL. HRQOL deteriorated with time since onset of IBS symptoms for some domains such as diet. For both instruments, a positive correlation was observed between low scores and intensity of pain and discomfort. IBS patients with a predominance of diarrhea (N=72) exhibited significantly greater impairment of HRQOL in the emotional domain than IBS persons with constipation predominance (N=65) (P<or=0.05). CONCLUSION IBS has a significant impact on HRQOL of patients. In addition, specific characteristics such as gender, symptom severity and time since onset of symptoms are predictive of more impaired health-related quality of life.

AbstractBackground: Migraine is a prevalent and incapacitating condition that affects individuals in the prime of their productive life, thus generating an economic burden for both society and healthcare systems. The direct annual healthcare costs of migraine in France were assessed over 10 years ago, and the current study updates these figures. Objective: The objective of this study was to determine the economic cost (primarily direct costs) of migraine and other episodic headache in France based on a general population survey of headache, the GRIM2000 (Groupe de Researche Interdisciplinaire sur la Migraine). Design: From a representative general population sample of 10 585 individuals aged ≥15 years in France in 1999, 1486 individuals experiencing headaches were identified and interviewed regarding healthcare resource consumption in the previous 6 months. By applying unit costs to the resource data, costings (in 1999 values) were determined for physician consultations, hospitalisation, medication use and diagnostic/laboratory tests, and evaluated from a healthcare system perspective. Information on absenteeism and lost productivity was derived from the Migraine Disability Assessment Score (MIDAS) questionnaire. Results: The prevalence of migraine (including migrainous disorder) was determined to be 17%. Total annual direct healthcare costs were estimated to be €128 per individual with migraine in 1999, corresponding to €1044 million when extrapolated to all individuals experiencing migraine and aged ≥15 years. Around two-thirds of this cost accrued to the social security system (€698 million; €85 per individual). The total annual direct cost of other forms of episodic headache was much lower at €28 per individual (social security cost €18); with a prevalence of 9.2%, the annual national direct cost for other forms of episodic headache totalled €124 million. The principal cost element was physician consultations. However, it was found that many individuals had never consulted a physician for their headaches, and self-medication contributed substantially to the medication costs (the second greatest cost factor for migraine). The cost per individual rose steeply with increasing severity of headache. Conclusion: The direct healthcare costs of migraine do not seem to have risen significantly over the past decade. A small minority of individuals with more severe headaches consume most of the healthcare resources devoted to migraine, while most individuals generate relatively low direct costs. The total annual direct costs in France for migraine are almost 10-fold higher than those of other episodic headache.

Few recent comparative data exist on smoking habits in the Middle East and North Africa (MENA) region. The objective of this analysis was to evaluate smoking patterns in a large general population sample of individuals aged ≥ 40 years in ten countries in the region (Algeria, Egypt, Jordan, Lebanon, Morocco, Saudi Arabia, Syria, Tunisia, Turkey and United Arab Emirates), together with Pakistan, using a standardised methodology. A random sample of 457,258 telephone numbers was generated and called. This identified 65,154 eligible subjects, of whom 62,086 agreed to participate. A screening questionnaire was administered to each participant, which included six questions relating to cigarette consumption and waterpipe use. The age- and gender-adjusted proportion of respondents reporting current or past smoking of cigarettes or waterpipes was 31.2% [95% CI: 30.9-31.6%]. This proportion was significantly higher (p < 0.001) in men (48.0%) than in women (13.8%), but no relevant differences were observed between age groups. Smoking rates were in general lowest in the Maghreb countries and Pakistan and highest in the Eastern Mediterranean countries, ranging from 15.3% in Morocco to 53.9% in Lebanon. Consumption rates were 28.8% [28.4-29.2%] for cigarette smoking and 3.5% [3.4-3.6%] for waterpipe use. Use of waterpipes was most frequent in Saudi Arabia (8.5% of respondents) but remained low in the Maghreb countries (< 1.5%). Cumulative cigarette exposure was high, with a mean number of pack · years smoked of 18.5 ± 20.5 for women and 29.1 ± 26.2 for men. In conclusion, smoking is a major health issue in the MENA region.

BACKGROUND Occasional cases of acyclovir resistance have been documented in the treatment of herpes simplex virus (HSV) infection. Thirty-eight subjects with acyclovir-resistant infections were identified in an epidemiological surveillance program involving 1811 HSV-infected subjects in France. METHODS Twenty-three index cases from whom acyclovir-resistant HSV strains had been isolated were compared with 46 control subjects matched for immunological status. Sociodemographic characteristics, features of the acyclovir-resistant HSV episode, history of HSV infection, treatment, outcome, and immunological history were recorded. RESULTS Twenty-two index case patients presented with immunodepression. Sixty-five percent reported clinically manifest recurrences, compared with 33% of matched control subjects. Significantly more index case patients had used antiviral drugs, and they had used them more often than had control subjects. However, 26.1% of index case patients reported no antiviral exposure in the previous 2 years. Two-thirds of the strains recovered from the index case patients were isolated because of suspicion of clinical resistance to acyclovir. CONCLUSIONS Clinical treatment resistance is associated with acyclovir-resistant HSV strains, but acyclovir-resistant strains were also isolated from treatment-naive subjects.

BACKGROUND Bronchial asthma is the most frequent chronic respiratory disease in both adults and children. The prevalence and burden of asthma vary considerably between different regions of the world. Information on asthma in Africa is fragmentary and relatively old. OBJECTIVE The objective of this cross-sectional epidemiological survey was to determine the prevalence and burden of asthma in the North African countries of Algeria, Morocco and Tunisia using the methodology developed in the Asthma Insights and Reality (AIR) programme. METHODS A general population sample was generated using a stratified sampling method based on randomly-generated lists of telephone numbers. The target sample consisted of 10,000 households in each country, which were contacted by telephone. A structured interview was proposed. Two screening questions were asked to identify subjects with asthma. Subjects who met these criteria were then questioned in more detail about their asthma. RESULTS Of 30 350 households contacted, 1090 subjects with asthma were identified of whom 872 provided complete data. The age- and gender-adjusted prevalence of asthma was 3.45% [95% CI: 3.09 3.80%] in Algeria, 3.89% [95% CI: 3.52 4.27%] in Morocco and 3.53% [95% CI: 3.18 3.89%] in Tunisia. Prevalence was highest in children and older adults, and in urban areas. Annual incidence rates ranged between 28/10,000 in Tunisia and 46/10,000 in Algeria. 74.3% of adults reported being handicapped by their asthma all or most of the time, 26.4% reported a visit to a hospital emergency department in the previous year and 23.9% absence from work or school due to asthma. 48.0% reported that their sleep was very or quite disturbed by asthma. CONCLUSIONS The prevalence of asthma in the Maghreb countries is moderate, but its impact is high.
