Clinical criteria for the diagnosis of bullous pemphigoid: a reevaluation according to immunoblot analysis of patient sera.

BACKGROUND: We previously proposed a set of 4 clinical criteria for the diagnosis of bullous pemphigoid (BP) that consisted of age greater than 70 years, absence of atrophic scars, absence of mucosal involvement and absence of predominant bullous lesions on the neck and head. These results have been challenged because direct immunoelectron microscopy (IEM), which was used as the standard diagnostic criterion in our initial study, does not identify the different antigens of the basement membrane zone. OBJECTIVE: To reassess the validity of these clinical criteria for the diagnosis of BP using immunoblot analysis of patient sera as the main diagnostic criterion, in order to precisely identify the antigens recognized by patient sera. METHODS: One hundred and eighty-nine sera from patients with various subepidermal autoimmune blistering diseases (AIBDs) were tested by immunoblotting using dermal and epidermal extracts. IEM was used as a complementary diagnostic procedure in a few patients whose serum recognized BPAG2 exclusively or was negative in immunoblotting. RESULTS: 142 patients (75%) had at least 3 of the 4 clinical diagnostic criteria. Sera from patients who lacked the set of BP clinical criteria were more frequently immunoblot negative (34%) than sera from patients who had the criteria (18%; p = 0.025). BPAG1 was more frequently recognized by sera from patients with the set of BP clinical criteria (78%) than by sera from patients without the criteria (45%; p = 5.10(-4)). In contrast, BPAG2 was recognized by a great number of sera from patients who lacked the criteria of BP (71%), which was in accordance with the presence of numerous patients with cicatricial pemphigoid in this group. Among patients with various subepidermal AIBDs, the diagnosis of BP could be made with a sensitivity of 86%, a specificity of 90% and an excellent prognostic positive value over 95%, if 3 of these clinical criteria were present. CONCLUSION: These results confirm the interest of this set of clinical criteria for the rapid diagnosis of BP.

[Risk factors for cutaneous wart onset in transplant recipients].

INTRODUCTION: Transplant recipients are at increased risk for cutaneous warts. We have investigated the delay of their onset warts and some possible risk factors for their occurrence. PATIENTS AND METHODS: Clinical data were summarized on a standard question and examination sheet. Warts were diagnosed on clinical grounds and course duration assessed on patients' report. Immunosuppressive therapy and HLA group were collected from clinical transplantation records. An actuarial curve was used to evaluate the delay of onset of warts. To compare associated risk factors among the two groups (patients with warts and patients without warts) at 1 year and 3 years following transplant, single variate analysis was performed. RESULTS: At the time of transplant, the prevalence of warts was 16 p. 100. It was increased with the duration of immunosuppression: 23 p. 100 at 1 year, 35 p. 100 at 3 years, 45 p. 100 at 5 years and 54 p. 100 at 7 years. Warts were multiple and principally localized on the hands. Transplant recipients without cutaneous warts 3 years after transplant had less intensive immunosuppressive therapy than the group with cutaneous warts. No association was found between age, sex, HLA markers, actinic keratosis and wart onset. DISCUSSION: The prevalence of warts increases with the duration of transplantation. Cutaneous warts are generally multiple and have a chronical course without spontaneous remission. More intensive immunosuppressive therapy increases their occurrence. This trial cannot evaluate the association between carcinoma and warts. On the basis of our study, there is no relationship between actinic keratosis and warts, nor HLA markers and warts.

[Notoriety of the French dermatology: analysis through dermatological publications].

INTRODUCTION: The aim of this study was to evaluate the publications of French dermatologists in medical journals. METHODS: All papers published in 1998 and indexed in PubMed were searched under the names of all dermatologists listed in a French registry of hospital dermatologists and analyzed. A sample of 8 departments of dermatology in University hospitals was selected at random and the publications from these departments were compared to those from the departments of rheumatology in the same hospitals. In addition the publications of French, German and Italian dermatologists were compared for the years 1989, 1994 and 1999. RESULTS AND CONCLUSION: In 1998, 452 papers were published by French dermatologists. This was more than for rheumatologists in the selected sample (133 vs 82). The impact factor was rather low (1.8 +/- 3), in part because many papers (43 p. 100) were written in French. In addition original studies and research papers accounted for only 20 p. 100 of all papers. The numbers of papers devoted to clinical research had increased in the last 10 years and compared favorably with German and Italian dermatology. In contrast, the number of research papers had decreased in the last 10 years in strong contrast with the dramatic increase of research papers originating from Germany.

[Dermatology in private practice in France in 2000].

OBJECTIVES: Data regarding French dermatological practice are scarce. Our objective was to identify the skin disorders most commonly diagnosed by office-based dermatologists. We also documented the severity of these skin disorders, as reflected by the repercussions on patient's everyday life, and the way physicians managed patients. DESIGN: We carried out a one-day survey of visits to a randomly selected sample of 900 French office-based dermatologists. The randomization was stratified according to the five French different dialing area codes. RESULTS: Office-based dermatologists saw 6411 patients with 7839 skin disorders during the survey. The daily number of visits to French dermatologists was estimated at 47 000 and the annual number between 12 and 14 millions. Office-based dermatologists mostly managed warts, acne, nevus, dermatitis, malignancies and pre-malignancies, fungal infection and psoriasis. Repercussions on patients'everyday life were assessed by physicians as important or very important in 28 p. 100 of cases. Half of the patients received topical treatment, 20.5 p. 100 a systemic drug and 40 p. 100 a minor surgical procedure (including cryotherapy). CONCLUSION: Although dermatologists frequently see benign skin disorders such as warts or nevus, more severe diseases represent an important part of their activity.

[Survey on the activity of hospital departments of dermatology in France].

INTRODUCTION: The Collège des Enseignants de Dermatologie de France initiated a study to assess the activity of the departments of dermatology in French hospitals. We report the results of this survey. MATERIAL AND METHODS: The study was conducted during a randomly selected week in the year 2000. An anonymous questionnaire was sent to all the departments of dermatology in the hospitals in France and was completed for each patient leaving the hospital during that week. The data collected were: the type of establishment, admission method, hospitalization method, type of pathology, motive for hospitalization, length of hospitalization and type of treatment used. RESULTS: The response rate was of 96 p. 100 for the University hospital centers and 80 p. 100 for the non-university hospitals. The number of patients treated per year was of 65 628 for the University hospitals and of 16,000 for the others. Ninety percent of the hospitalizations corresponded to direct admissions. The pathologies at the origin of the majority of yearly hospitalizations were, for the University hospitals: melanoma, leg ulcers, highly specialized dermatoses and systemic diseases and for the other hospitals: leg ulcers, HIV infection, highly specialized dermatoses and erysipela. The pathologies requiring the greatest number of hospitalization days were melanoma, leg ulcers, erysipela and highly specialized dermatoses. DISCUSSION: This study shows that the activity in the departments of dermatology is centered on pathologies that are clearly severe in terms of Public Health (oncology, infectious diseases and angiology). It also shows the efforts made for the management of patients in out-patient settings.
