Immunogenicity and booster efficacy of pre-exposure rabies vaccination.

A multivariate analysis was used to identify factors influencing the immunogenicity of rabies vaccine and to assess the efficacy of booster injections in a cohort of 407 people monitored prospectively for 10 years after primary vaccination. Rabies vaccine (HDCV or PVRV) was injected by intramuscular route either on days 0 and 28 or on days 0, 7 and 28. All the participants received a booster injection on day 365.

[Laparoscopic diagnosis of stenosing eosinophilic jejuno-ileitis].

Introduction: Eosinophilic gastroenteritis of unknown origin could be isolated or integrated in idiopathic hypereosinophilic syndrome. Clinical expression is variable since the lesion may affect any area of the gastrointestinal tract and any layer of the wall.

Exegesis: A 25-year-old male patient had digestive symptoms such as peritoneal, obstructive and diarrheal signs, associated with blood eosinophilia, giving evidence for eosinophilic jejuno-ileitis.

[Tick-born encephalitis].

Introduction: Tick-borne encephalitis (TBE), a disease contracted through tick bites, is caused by a Flavivirus. Its geographical distribution comes from the geographical distribution of the reservoir of infection--i.e.

Pre-exposure rabies vaccination: strategies and cost-minimization study.

An alternative strategy for pre-exposure rabies vaccination to the institutional recommendations of the World Health Organization and the Centers for Disease Control and Prevention is proposed based on recent long-term follow-up of post-vaccinal seroconversion rates. The alternative strategy uses the same primary series (i.e.

[Rabies in France: an update].

Introduction: In 1996, rabies was responsible for more than 35,000 deaths worldwide. Three cases of human rabies that had been contracted abroad were diagnosed in France during the same year. Cases notified in 1997 followed exposure outside the country.

Predictive factors for the neutralizing antibody response following pre-exposure rabies immunization: validation of a new booster dose strategy.

A prospective cohort of 312 subjects who received pre-exposure rabies immunization and who were monitored serologically with a 10-year follow-up was assessed using multivariate analysis. The aim was to propose a new booster dose strategy by identifying predictive factors for the durability of the neutralizing antibody response. Evaluation bore on several factors relating to: (1) demographic characteristics: age, gender; (2) vaccines: type of vaccine (HDCV or PVRV), injection regimen (D0-D28-D365 or D0-D7-D28-D365) and vaccine lots' antigenic potency; and (3) resulting antibody titers.

Antibody persistence following preexposure regimens of cell-culture rabies vaccines: 10-year follow-up and proposal for a new booster policy.

Subjects (n = 312) received either the human diploid cell rabies vaccine (HDCV) or the purified Vero cell rabies vaccine (PVRV) according to either two-injection (days 0 and 28) or three-injection (days 0, 7, and 28) primary regimens. They received a booster injection at 1 year. Rabies antibody levels were measured after the primary series and the booster and then each year for the next 10 years.

[Immunoprophylaxis of rabies: current recommendations].

Pre-exposure rabies vaccination should comprise 3 injections (day 0, day 7, day 28) followed by boosters 1 year later then every 5 years. Populations who are particularly exposed due to occupation, regular contact with animals in endemic areas during leisure activities or holidays should be vaccinated, especially if access to post-exposure treatment is difficult. Post-exposure treatment should comprise 5 injections (day 0, day 3, day 7, day 14, day 28) which must be given with specific immunoglobulins on day 0 if there are penetrating wounds.

[Granular-cell tumor: review of the literature apropos of a case of bronchial site].

Abrikossoff's tumor, also called granular cell tumor, is an uncommon condition, generally benign, which can affect every organ and specially skin and tongue. The authors report an observation of a bronchial tumor and review the literature. Possible relapse after treatment, locally or everywhere in the body, may occur as local or regional complication that may necessit heavy surgery.

[Human periorbital dirofilariasis].

We present the case of a 72 year-old-woman with recurrent periocular inflamatory mass caused by an infection with Dirofilaria repens. The zoonotic infection is spreading by mosquito vectors from dogs to humans. Residence in endemic areas (ex-USSR, Italy, Sri Lanka, Southeastern United States) should always be suspected in patients with this type of symptomatology.

[Brucellosis among occupationally exposed people: evaluation of immunological tests after vaccination].

For the evaluation of immunological tests during an epidemiological survey and of vaccination with the PI brucellin vaccine, in an occupationally exposed environment, a sample group of 354 subjects was studied. The vaccinal strategy was based on the outcome of a skin test for hypersensitivity: the PS brucellin test. In this framework, the serological status and evolution of individuals with positive or negative reactions to this test were analysed.

[Pre-exposure rabies immunization in occupational exposed milieu. A 5-year prospective and comparative study of immunogenicity].

Pre-exposure rabies immunization has been the object of numerous immunogenicity studies with cultivated cell vaccines. Several primary immunizations and booster injection schedules have been suggested. The purpose of the present study was to compare simultaneously the immunogenicities of two vaccines at 5 years and those of two primary immunization schedules with a booster injection at 1 year.

[Brucella vaccination in professionally exposed subjects. Prospective study].

This prospective phase IV study on cohort concerns a vaccine made of the phenol-insoluble fraction of Brucella abortus biotype 1 (B19 strain). Three hundred and three professionally exposed subjects entered the study; 161 out of 182 subjects (88.5 percent) with negative response to an intradermal test for detection of previous contamination accepted to be vaccinated.

Immunisation with canarypox virus expressing rabies glycoprotein.

Poxviruses have many useful features as vectors for genes that carry immunising antigens from other viruses, such as ease of production and induction of cellular and humoral immunity, but there is concern about the safety of vaccinia virus. We turned to an avian poxvirus (canarypox); this virus undergoes abortive replication in mammalian cells that enables presentation of early gene products to the immune system. Canarypox virus was used as a vector for the rabies glycoprotein G gene.

[Animal bites. Epidemiology and infection risks].

A review of 5,116 cases of animal bites (587 of which were studied prospectively) has shed some light on their epidemiological aspects and on the risk of infection they carry. It has also led to a more objective assessment of the real effect of the therapeutic and prophylactic measures usually applied in such cases. The most frequent wounds are those of the hands and face, the former rising an infectious problem, the latter a predominantly cosmetic problem.
