Increase in reported adverse events following seasonal influenza vaccination among the French armed forces, 2008–2009: Possible role of stimulated reporting and background cases of influenza-like infection

In September 2009, an increase in seasonal influenza vaccine adverse events (VAE), compared with reports for previous years, was detected among the French armed forces in the setting of an extended immunization campaign. This work presents the results of this investigation. VAE were surveyed among all French military personnel from 2008 to 2009 by Epidemiological Departments of the French Military Health Service. For each case, a notification form was completed, providing patient and clinical information. Case definitions were derived from the French drug vigilance guidelines. Three types of VAE were considered: non-serious, serious and unexpected. Incidence rates were calculated by relating VAE to the number of vaccine doses injected. Forty-seven seasonal influenza VAE were reported in continental France: 18 in 2008 and 29 in 2009. The annual reporting rate was higher in 2009 (31.6 vs 16.6 VAE per 100,000 injections, respectively). The highest monthly incidence was observed in September 2009 (60.8 events per 100,000 injections). Two other peaks were observed in February 2008 and March 2009. The incidence in September 2009 was not significantly different from the incidences in February 2008 and March 2009. It was observed that incidence peaks occurred during influenza epidemic periods. One serious neurological VAE was observed. The increase in seasonal influenza VAE in late 2009 mainly involved non-serious events, and could reflect stimulated reporting in the context of the A(H1N1)pdm09 pandemic. VAE reporting rates were highest during influenza epidemic periods, which could be explained by VAE being wrongly attributed to the vaccine when symptoms could reflect coincident background cases of viral infection.

Blood and body fluid exposures in the French military

Occupational exposure to blood and body fluids (BBFs) is a hazard of many occupations, particularly hospital-based health care providers. However, non-hospital-based health care workers (HCWs) and other personnel not providing health care are also at risk. To present the results of surveillance of accidental exposure to BBFs among non-hospital-based French military personnel between 2007 and 2009, comparing different occupational categories. The study population included all French military personnel subjected to occupational BBF exposure in a non-hospital setting. BBF exposure was defined as any percutaneous (needlestick injury, scalpel cut, etc.) or mucocutaneous (splash to mucosa, eyes or non-intact skin) exposure to blood, a biological fluid contaminated with blood or a fluid known to transmit blood-borne pathogens. Between 1 January 2007 and 31 December 2009, 704 occupational BBF exposures were reported in non-hospital-based French military personnel. Annualized BBF exposure incidence rates were statistically different among health care workers in non-hospital settings, firefighters, 'gendarmes' and other military personnel, with respectively 38.7, 5.4, 0.8 and 0.1 exposures per 1000 persons per year. Among the 97 cases of HIV post-exposure prophylaxis (PEP) initiated, the source patient's HIV status was unknown in 78 cases (84%). These results suggest that the appropriateness of HIV PEP initiation in the French military should be reviewed. Adapting French guidelines for managing BBF exposure, for non-hospital-based environments should be considered.

Plasmodium vivax Malaria among Military Personnel, French Guiana, 1998-2008

We obtained health surveillance epidemiologic data on malaria among French military personnel deployed to French Guiana during 1998–2008. Incidence of Plasmodium vivax malaria increased and that of P. falciparum remained stable. This new epidemiologic situation has led to modification of malaria treatment for deployed military personnel.

Sclérose latérale amyotrophique (SLA) chez les militaires français : enquête rétrospective

An apparent increased risk for developing Amyotrophic Lateral Sclerosis (ALS), a multifactorial neurodegenerative disease, is considered to exist in the military population. ALS military and veteran patients were retrospectively recruited in April 2008 by searching medical data (Hippocrate) and repayment data (Erasme) of the French National Military Health Care Fund (Caisse nationale militaire de sécurité sociale, CNMSS) from de January 1991 to December 2007. We report a series of 73 patients, 69 male and four female, average age of 52.5 years (range 27 to 72 years) with a peak of patients in the 50-59 year age class. The branch of military service was Army (n=26 patients), Air force (n=14), Navy (n=10) and State Police Force (n=22). The incidence among male active duty military personnel was stable from 2002 to 2007; it was less than the general population (1.7/100,000 per year in 2007), but higher in the 40-44 and 50-54 year age classes (1.90 and 5.07/100,000 per year in 2007 respectively). Duration of active duty was on average 31 years. The retrospective nature of the data and the incomplete population with loss of retired military personnel without CNMSS affiliation are limitations of our study. Another means of collecting all cases of ALS among French military personnel and veterans would be to conduct a search in the 17 ALS centers in France with analysis by occupational activity for entire career.

Expositions sexuelles au VIH dans les armées françaises de 2005 à 2007

Non-occupational HIV exposure in the French forces has been placed under epidemiological surveillance since 2000. This surveillance programme provides an indirect indicator of risky sexual behaviour among military personnel.All cases of non-occupational exposures in French military personnel that meet the notification criteria, wherever they occur, are reported by a military physician, with data being collected from 2005 to 2007.Between January 2005 and December 2007, 2241 cases of sexual exposure within the French forces were filed. The annual incidence was 214.3 per 100,000 with an average patient age of 26 years. Sexual exposures concerned men in 99.2% of cases and occurred overseas in 92.9% of cases. Partners were sex-workers in 66.7% of cases. Failure to use condoms adequately during sexual intercourse was reported in 15.5% of cases. In cases where condoms were used, exposure to HIV resulted either from condom rupture or slippage. Postexposure HIV prophylaxis was prescribed in 70.5% of cases.The majority of cases of sexual exposure reported in the French armed forces involved high risk of HIV transmission. However, since the beginning of surveillance in 2000, no cases of HIV seroconversion have been reported following postexposure antiretroviral prophylaxis. The non-occupational postexposure prophylaxis strategy is not in question.

Caractérisation de groupes de consommateurs de médicaments psychotropes : application d’un modèle d’analyse en classes latentes aux bases de données de la Caisse régionale de l’assurance-maladie des Pays-de-la-Loire

L’objectif de l’étude est d’analyser les remboursements de buprénorphine haut dosage et de méthadone, effectués au cours de l’année 2007 par la Caisse nationale militaire de Sécurité sociale au profit des militaires d’active. Il était observé 181 consommateurs militaires de médicaments substitutifs aux opiacés (MSO) soit 167 hommes et 14 femmes répartis dans l’ensemble des trois armées, de la gendarmerie et des formations rattachées. L’âge moyen des consommateurs était de 26,6 ans. L’ancienneté moyenne de service était de 6,1 ans. La prévalence de la consommation des MSO chez les militaires (52 p. 100 000) est faible par rapport à la population générale. Selon les critères du Plan national inter-régimes de l’assurance maladie pour la lutte contre les fraudes, cette population n’est quasiment pas concernée par les actions prioritaires prévues par le plan. Les médecins généralistes sont les prescripteurs de MSO dans 88 % des délivrances. Un seul prescripteur militaire a été identifié. On a observé que le médecin militaire est mis quasiment systématiquement en dehors du processus de substitution. C’est seulement au terme d’une analyse approfondie de la situation de l’individu concerné que la décision d’aptitude à un poste donné pourra être prise.The use of psychoactive drugs by militaries is not compatible with the analytical skills and self-control required by their jobs. Military physicians take this problem into consideration by organising systematic drugs screening in the French forces. However, for technical reasons, opiates are not concerned by this screening with the agreement of the people concerned. The estimated number of militaries who use an opiate substitute may be an approach of heroin consumption in the French forces. This study describes buprenorphine and methadone reimbursements made during 2007 by the national military healthcare centre to French militaries.Each French soldier is affiliated to a special health insurance. The national military healthcare centre has in its information system, all the data concerning drug reimbursement made to French military personnel. This is a retrospective study of buprenorphine and methadone reimbursements made during 2007 by the military healthcare centre, to militaries from the three sectors of the French forces, and from the gendarmerie and joint forces. Only one reimbursement of one of these two drugs during this period allowed the patient to be included in our study. Daily drug dose and treatment steadiness profile have been calculated according to the criteria of the French monitoring centre for drugs and drug addiction. The criteria of the National guidelines against frauds have been used to identify misuse of these drugs. Doctors’ shopping behaviour has also been studied. Finally, the nature of the prescriber and the consumption of other drugs in combination with opiate substitute have been analysed.One hundred and eighty-one military consumers of opiate substitute drugs (167 men and 14 women) participated. This sample included people from the three sectors of the French forces as well as from the gendarmerie and from the joint forces. The average age of the consumers was 26.6 years (20–42 years). The average length of service was 6.1 years (maximum 22 years service). One hundred and fifty-nine militaries had been delivered buprenorphine, 15 had been delivered methadone and seven had been delivered both. The prevalence of opiate substitute drug consumption by the militaries (52 per 100,000) is lower than in general population. According to the criteria of the National Healthcare Insurance, this population is not affected by abuse or fraud behaviour. Doctors’ shopping behaviour is unusual. Opiate substitutes are prescribed by general physicians in 88% of issues. Only one prescriber was a military physician. An analysis of reimbursement of some drugs associated with opiate substitute has been made. The sampled military consume more psychoactive drugs (anxiolytics, antidepressants, hypnotics) than the French population under opiate substitution.In our observation, the military physician is almost always excluded the process of substitution. His/her different responsibilities of care, but also in determining the working aptitude, lead to dissimulation behaviour by the militaries. The difficulty for military physicians is to identify such consumption. They have to evaluate the capacity to work through a physical and psychological examination.

Situation actuelle et perspectives de la prophylaxie du paludisme chez le voyageur et dans les forces armées

Malaria remains a major public health problem, both for travellers and for the 40,000 French soldiers deployed each year to endemic areas. Epidemiological data show that imported malaria (IM) is on the increase, and that migrants account for more than 60% of malaria cases notified each year in France. The increase in IM among French military personnel is explained by prematurely terminated chemoprophylaxis on return, repeated short missions, and more cases of P. vivax and P. ovale infection. The choice of chemoprophylaxis depends mainly on the level of chloroquine resistance in the country visited. The atovaquone-proguanil combination is well tolerated and only requires 7 days of intake on return from the endemic area. Doxycycline monohydrate is cheaper and better-tolerated than mefloquine, and is thus preferred for French military personnel. However, its short half-life necessitates very good compliance. Chemoprophylaxis should be combined with vector control measures and with personal protection (impregnated bednets, protective clothing, repellents, and indoor insecticide spraying). The need for these measures should be clearly explained before departure, during the stay, and after return.

Epidemiology of the metabolic syndrome in 2045 French military personnel (EPIMIL study)

The Metabolic syndrome is considered to be an important public health problem, but few epidemiological studies have defined the present situation in France. EPIMIL is a prospective epidemiological study that began on February 1, 2003. This study was designed to identify the clinical and laboratory parameters of metabolic syndrome and cardiovascular risk factors in a population of 2045 male military personnel based in the Paris region. The initial 1-year cross-sectional study will be followed by a 10-year follow-up and patient care. The 2045 subjects included 185 (9%) presented at least 3 of the 5 NCEP ATP III criteria defining metabolic syndrome. They were significantly older (42.2 +/- 8.5 yrs) than the other subjects (37.3 +/- 8.7 yrs, P<0.001), had a higher BMI (29.5 +/- 3.4 vs 24.8 +/- 2.9 kg/m2, P<0.001) and a greater body weight at age 20 (75.4 +/- 11 vs 70.4 +/- 8.5 kg, P<0.01). Smoking, little physical activity and family histories of diabetes and arterial hypertension were more frequent in these men. While levels of the cholesterol and CRP us were higher, Lp(a) and homocysteine concentrations were normal. Plasma insulin and BMI (r = 0.456 P<0.0001) and plasma insulin and waist circumference (r = 0.446 P<0.0001) were well correlated. Lastly, plasma insulin, free fatty acids and cardiovascular risk increased steadily with the increase in the number of metabolic syndrome criteria. These results in a large and particularly uniform population of men show the prevalence of metabolic syndrome in adult men, and demonstrate its link with insulin resistance. Men with several risk factors require specific care, particularly for hypertension and dyslipidemia; the effectiveness of this care will be evaluated during the follow-up period.

Cost-Benefit Analysis of Vaccination against Tick-Borne Encephalitis among French Troops

French troops are exposed to tick-borne encephalitis (TBE) during their tours of duty in the Balkans. This disease, potentially serious because of its lethality and morbidity, has an effective vaccination. The epidemiological characteristics of TBE in the Balkans are not well known. In order to provide the French Department of Defence with arguments on the utility of vaccinating troops on missions in this area of Europe, we conducted a cost-benefit study. Through a decision analysis, we estimated the net benefit of a three-injection vaccination programme for all French military personnel in the Balkans versus no vaccination during a period from 2004 to 2014. We used a review of the literature to estimate the parameters necessary for the present study: the disease's morbidity and death incidence rate; the disease's sequelae; and the adverse effects of the vaccination. The initial hypothesis of the seroconversion rate of TBE in the Balkans was 834 per 100,000 person-years. Human life was valued in Euro (year 2004 values) by calculating the amounts paid by the French Department of Defence to military personnel in case of disabling sequelae and to their heirs in case of death. The net benefit was negative: -5.68 million Euro. The vaccination programme's cost was 10.05 million Euro. 121 cases of TBE could be prevented by this vaccination; however, the sensitivity analysis showed that the results are closely related to the incidence of the disease. Very high incidence rates of TBE were initially hypothesised compared with what has actually been reported. As a result, the vaccination programme against TBE for French military personnel should not be implemented unless the objective of the armed forces is to prevent all cases of TBE and they are willing to assume the cost of doing so.

Efficacy of Permethrin-Treated Uniforms in Combination with DEET Topical Repellent for Protection of French Military Troops in Côte d’Ivoire

In 2000, 22,000 French military personnel were deployed overseas. The French military health service implemented a vector control strategy including personal protection by the use of permethrin preimpregnated battlefield uniforms (BFUs) and the application on the skin of a topical repellent (50% DEET). In 2000, French forces used an industrial process to impregnate cloth with permethrin by soaking it before cut-out of the BFU. A study was implemented in four experimental huts in Côte d'Ivoire to assess the field efficacy of the impregnated BFUs and their resistance to washing. Taking into account the systematic variations in each variable in the field and using a modeling based on logistic regression and discriminant analysis, this study showed that after 6 h without reapplication, the protective effects of the use of DEET as skin repellent was not significant, perhaps due to the high density of Anopheles mosquitoes during the night catching sessions and an average time of effective repellency of < 2 or 3 h in the field. The analysis also showed that the French process of industrial impregnation of permethrin of the BFU offered in 2000 some protection from mosquito bites but not enough to reduce significantly the incidence of malaria among nonimmune troops. No positive or negative interaction was noted when DEET and the impregnated BFUs were used together.

In the German Federal Republic: The maintenance of military graves in accordance with the Geneva Conventions

The Central Tracing Agency in Geneva has always had, amongst many other tasks in time of war, that of tracing the graves of missing military personnel. If we are more especially considering the Second World War, we can see that this activity began for the Central Prisoners of War Agency (its official title at that time), when hundreds of thousands of regimental enquiries were opened for French prisoners of war in Germany, in order to discover the fate of French military personnel missing during the summer of 1940.

Political Parties and the French Army since the Liberation

In a recent article in Le Monde, a military writer remarked that ‘A country has the army it merits.”1 The expression is an old one. For a hundred years at least, French politicians and French military personnel have been quoting one another to the effect that the army is but the reflection of the state. But in a democracy, the strength of an army is not so much a question of merit as one of desire, desire as expressed by the people through the votes of their representatives. Certainly, it has little or nothing to do with international necessity.
