[Seroprevalence of viral hepatitis A in France in homosexuals and intravenous drug users].

OBJECTIVES: In industrialized countries with a high level of sanitation, immunity against hepatitis A (HVA) is not acquired during childhood, and infection typically occurs in adults, mainly in travelers returning from developing countries where infection is endemic. However, the introduction of hepatitis A virus (HAV) among certain population groups, such as intravenous drug users (IVDU) or homosexual men, leads to a significant increase in the disease. We conducted a retrospective analysis of seroprevalence of anti-HAV antibodies. METHODS: The study group included 296 patients (174 homosexual men and 122 IVDU) for comparison with 76 control subjects (nurses in pediatric wards and workers in hospital kitchen). RESULTS: We found a significantly higher anti-HAV seroprevalence among less than 35-year old IVDU, HIV positive or negative, in comparison with control subjects but not among homosexual men, whatever their HIV status. CONCLUSION: Our experience illustrates that HVA is a health risk for IVDU in industrialized nations, and given its morbidity among adults population, IVDU should receive HVA vaccine.

Hepatitis B-like infection in a Pacific white-sided dolphin (Lagenorhynchus obliquidens).

A Pacific white-sided dolphin (Lagenorhynchus obliquidens) developed clinical signs, serum biochemical values, and serologic viral markers consistent with chronic persistent hepatitis caused by a hepatitis B-like virus. The hepatitis had a sporadic cyclical pattern of lethargy, inappetance, and icterus, with leukocytosis and increased serum activities of alanine transaminase, aspartate transaminase, and gamma-glutamyltransferase. The serum from this dolphin contained hepatitis B virus core antibodies, hepatitis B surface antibodies, and hepatitis B viral DNA. Supportive treatment consisted of administration of antibiotics, cimetidine, menadiol sodium diphosphate, and vitamin/dextrose supplementation. A clinically normal killer whale (Orcinus orca) housed in the same pool had serum hepatitis B surface antibodies, suggesting immunologic responsiveness and that this disease was not species-specific.

Cardiovascular changes in infants with beta-hemolytic streptococcus sepsis.

Sequential hemodynamic and biochemical changes were studied in 24 infants with sepsis due to beta-hemolytic streptococcus to define the temporal patterns of physiologic events and to compare them in surviving (n = 11) and nonsurviving (n = 13) infants. Septicemia was documented by positive blood culture in all. Biophysical and biochemical measurements were obtained before and hourly, for 11 h after antibiotic therapy was initiated. Surviving infants had significantly higher Hct and systolic and mean arterial pressures than nonsurvivors. In nonsurvivors, low BP was associated with a concomitant rise in CVP and severe metabolic acidosis refractory to therapy. Although there were no differences in PaO2 or PaCO2 between survivors and nonsurvivors, arterial-alveolar oxygen gradients were significantly greater in nonsurviving infants. These data show cardiorespiratory and metabolic alterations that differentiate surviving and nonsurviving infants with beta-hemolytic streptococcal septicemia.
