A unique seroepidemiologic situation for hepatitis B markers in Guadeloupe. Results of a prospective study in blood donors.

Screening for HBsAg, anti-HBc, anti-HCV and ALAT levels is now performed on donated blood to prevent post-transfusion hepatitis. A prospective study of 2,368 blood donors was performed in Guadeloupe (French West Indies) to determine risk factors associated with serologic abnormalities: 571 donations (24%) were positive for at least 1 of the 4 analyzed markers with 3.2% positive for HBsAg, 22% for anti-HBc, 0.8% for anti-HCV and 1.4% with ALAT > or = 45 IU/L. The anti-HCV prevalence was significantly different according to ALAT levels (P < 10(-4)). Transfusion history and work status (worker or serviceman) were found to be risk factors, with an odds ratio of 1.94 for serviceman population. Other unexpected risk factors were: number of years residency in Guadeloupe (progressively increased risk with the number of years), birthplace and residence in southern part of the island as well as the existence of gastrointestinal discomfort unrelated to viral hepatitis (odds ratio = 2.91). The results of this study show a unique epidemiologic situation for hepatitis B virus in Guadeloupe necessitating careful selection of blood donors.

[Bone and visceral manifestations of lipoatrophic diabetes. Apropos of a case].

Lipoatrophic diabetes, known by pediatricians as Lawrence-Seip disease or Berardinelli lipodystrophy syndrome, is an infrequent condition of which approximately one hundred cases have been published to date. A case in a 24-year-old female with a fifteen-year follow-up is reported. Manifestations included acanthosis nigricans, generalized lipoatrophy, hirsutism, muscle hypertrophy, and intellectual impairment. Biologic tests revealed insulin-resistant diabetes mellitus with major diet-dependent type V hypertriglyceridemia. The patient had nephrotic syndrome (focal and segmental endocapillary proliferative glomerulonephritis without dense deposits). Phosphorus and calcium determinations were normal, as were the endocrinologic tests. Roentgenograms of the bones disclosed increased density of axial bones and large epiphyseal defects with increased bone density as determined by osteodensitometric studies. The bone manifestations of this syndrome have been documented but are often overshadowed by the severe metabolic alterations.

Risk factors associated with hepatitis B or C markers or elevated alanine aminotransferase level among blood donors on a tropical island: the Guadeloupe experience.

Donated blood is currently screened for hepatitis B surface antigen (HBsAg), antibody to hepatitis B core antigen (anti-HBc), antibody to hepatitis C virus (anti-HCV), and alanine aminotransferase (ALT) levels to prevent posttransfusion hepatitis. A prospective study of 2368 blood donors was carried out in Guadeloupe (French West Indies) with a view to determining the risk factors associated with serologic abnormalities. Blood donors included in the study had to complete a questionnaire. Statistical analysis was performed on the data thus obtained: 571 donations (24%) were positive for at least one of the four analyzed markers. The results were that 3.2 percent were positive for HBsAg, 22 percent for anti-HBc, and 0.8 percent for anti-HCV, and 1.4 percent had ALT > or = 45 IU per L. A good correlation was found between anti-HCV and elevated ALT. Transfusion history and two socioeconomic categories (working class, military personnel) were found to be risk factors. Other risk factors were lifelong residence in Guadeloupe (with risk increasing with the number of years), birthplace and current residence in the southern part of the island, and the existence of gastrointestinal discomfort unrelated to viral hepatitis (odds ratio = 2.98). The results of this study illustrate the difficulty of implementing a preventive policy against posttransfusion hepatitis in a tropical area. The unique epidemiologic situation of Guadeloupe as regards hepatitis B virus has led to more restrictive criteria for the acceptance of blood donors.

Adult onset Still's disease and related renal amyloidosis.

A 57 year old woman presented with clinical and biological features of adult onset Still's disease. A kidney biopsy was performed at the onset of the condition and was found to be normal. Four years later, in view of a nephrotic syndrome, histopathological examination of a new kidney biopsy specimen was made and showed typical amyloid deposition. Renal amyloidosis was suspected in five previously reported cases but demonstrated by kidney biopsy in only two of them. In the present case renal amyloidosis was recorded after disease of four years' duration. The normality of the first renal biopsy specimen suggests the possibility of a direct relation between amyloidosis and adult onset Still's disease.

[Prevention of post-transfusion hepatitis in Guadeloupe: results after application of new measures for detecting blood donors potentially at risk].

One of the main concerns of blood transfusion centers is viral hepatitis as a direct result of blood transfusion. Ninety-five percent of these cases are non-A, non-B hepatitis. In order to prevent this disease, blood collections were screened for antibody anti-HBc as well as the level of activity of the alanine aminotransferase in 3,051 blood donors in Guadeloupe. this revealed a particular epidemiological situation, which caused this French country to be rated among moderate endemic zones for hepatitis B virus. As a result of this new screening procedure, 25 percent of the blood collected had to be discarded and was classified with prevalence rates of 21.8 percent HBc antibody, 2.9 percent HBs antigen, and 2.6 percent alanine aminotransferase (45 IU/l). Differences were noted according to sex, age, social-economical level and geographical origin of the blood donors. These data raised many significant questions regarding the vertical transmission of hepatitis B virus, the epidemiological situation of hepatitis B virus in the Guadeloupe population as well as in the rest of the French West-Indies, and also the type of action which must be taken against non-A, non-B hepatitis in a moderate endemic zone for HBV.

Neuroblastoma-like epidural localization in non-Hodgkin's lymphoma.

We report a case of non-Hodgkin's lymphoma with CNS involvement confined to the epidural space causing cranial suture diastasis. Cerebrospinal fluid and bone marrow were normal. Two cases only of cranial epidural lymphoma have been reported in the literature; in both cases, the leptomeninges were also involved but without suture diastasis.

[Angioimmunoblastic lymphadenopathy: a pathogenetic intersection between dysimmune, viral and lymphomatous diseases].

Angioimmunoblastic lymphadenopathy (AIL) still is a clinico-pathological syndrome with little known physiopathology. The advent of molecular biology has improved our understanding of this syndrome by characterization of the clonal cell. With this technique, combined with cytogenetics and immunohistochemistry, three pathological states have been individualized: 1) true AIL without evidence of monoclonal proliferation; 2) transformed AIL, and 3) AIL-like T-cell lymphoma. This clinical complex can be integrated in an evolutive continuum, starting with simple lymphoid hyperplasia and ending with frank malignant T-cell lymphoma.
