Herpes gestationis is a recurring pruritic, vesiculobullous disease of pregnancy and puerperium. Recently, Lawley et al (1979) reported a high frequency (38 per cent) of fetal morbidity and mortality in 40 cases of immunologically proven herpes gestationis. This study was undertaken to determine whether the antibody to skin basement membrane (found in most patients with herpes gestationis) is able to bind to the placenta basement membranes and thereby to threaten the pregnancy. We were unable to detect this antibody in the placental basement membranes of a patient with herpes gestationis, nor could we demonstrate that the anti-basement membrane antibody, found in the sera of herpes gestationis patients, binds to homologous or autologous placentas and fetal membranes. The importance of an accurate diagnosis and appropriate treatment of this condition is discussed. [less ▲]

BACKGROUND: The most common human prion disorder is Creutzfeldt-Jakob disease (CJD); it includes sporadic, familial, iatrogenic, and variant subtypes. Diagnostic tests aim at detection with the highest specificity of very small deposits of abnormal prion protein (PrP). METHODS: We used immunoquantitative PCR (iqPCR) to detect proteinase K-resistant PrP (PrPRes) in tissue from the middle frontal gyrus of 7 patients with sporadic CJD and 7 non-CJD cases. We compared iqPCR with routine optimized ELISA, Western blotting, and immunohistochemical analyses. RESULTS: The 4 methods showed similar 100% sensitivity and specificity for the diagnosis of CJD. Along with high specificity, however, iqPCR had a threshold for PrP(Res) detection at least 10-fold lower than that of the classic ELISA. CONCLUSIONS: iqPCR is a new method for PrPRes detection that combines 100% specificity with a detection threshold at least 10-fold lower than classic techniques. This method may improve the detection of minute PrPRes deposits in tissues and body fluids and thus be useful for diagnostic and sterilization applications. [less ▲]

A real-time immunoquantitative PCR (iqPCR) method for detection of Staphylococcus aureus enterotoxin B (SEB) was developed and evaluated using both pure cultures and foods. The assay consisted of immunocapture of SEB and real-time PCR amplification of the DNA probe linked to the detection antibody. iqPCR was compared to an in-house enzyme-linked immunosorbent assay (ELISA) using the same couple of capture-detection antibodies and to commercial kits for detection of S. aureus enterotoxins (SE). The iqPCR was approximately 1,000 times more sensitive (< 10 pg ml(-1)) than the in-house ELISA and had a dynamic range of approximately 10 pg ml(-1) to approximately 30,000 pg ml(-1). iqPCR was not inhibited by any of the foods tested and was able to detect SEB present in these foods. No cross-reactivity with SE other than SEB was observed. Application of iqPCR for detection of SEB in cultures of S. aureus revealed the onset of SEB production after 4 It of incubation at 22, 37, and 42 degrees C, which was in the first half of the exponential growth phase. The total amounts of SEB produced by the two strains tested were larger at 42 degrees C than at 37 degrees C and were strain dependent. [less ▲]

The Immunosuppression in Pancreas Transplantation was historically based on the fact that the pancreas is an extremely immunogenic organ. Quadruple drug therapy with polyclonal or monoclonal antibodies induction was the mainstay therapy since the introduction of Cyclosporine A. In the modern era of Immunosuppression, Mycophenolate Mofetil replaced Azathioprine while Tacrolimus-another potent calcineurin inhibitor-had-and still has-a difficult challenge to replaced Cyclosporine A, due to its potential diabetogenic effect. Thanks to the first two EuroSPK studies which prospectively tried to answer several questions in that field. But, the future challenge will be in understanding the impact of innate immunity and ischemic reperfusion injuries on the long term graft function. Hopefully, new drugs will be available and tested to block unspecific deleterious reactions to attenuate the proinflammatory response. It will be the aim of the third Euro SPK Stud [less ▲]

Allogeneic hematopoietic stem cell transplantation (HSCT) is used for the treatment of selected haematological malignancies. Its curative potential is based on two different mechanisms, i.e. the conditioning regimen and the graft-versus-host immunologic reactions. However, because of its toxicity, it is restricted to younger and fitter patients. These observations led several groups to set up new (less toxic) transplant protocols. These transplants are called nonmyeloablative HSCT or minitransplants. These are feasible with a relatively low transplant-related mortality even in patients up to 70 years. In addition, strong anti-tumor responses are observed in several haematological malignancies. [less ▲]

Environmental contaminants are suspected to have detrimental effects on marine mammal health. They were notably hypothesised to be involved in the severity and extent of catastrophic viral epidemics that recently affected the harbour seal (Phoca vitulina) population from the North Sea. High levels were indeed found in their tissues. However, the exact effects of those pollutants on free-ranging harbour seal health are not yet elucidated. In the field of immunotoxicology, in vitro cell culture techniques have been developed and are considered as valuable tools to assess specific toxicity mechanisms. The first objective of this study was to investigate the relationships between environmental contaminant levels found in harbour seal blood and lymphocyte proliferation responses in vitro. Indeed, wild harbour seal cells used in the framework of in vitro culture studies are isolated from the blood of animals that are contaminated, but little is known about the possible relationships between them. They were thus investigated in harbour seals from the North Sea. Peripheral blood leucocytes were isolated and cultured during 72h with Concanavalin A (ConA), a mitogen agent, to evaluate the lymphocyte proliferative responses as a stimulation index. The ConA-induced lymphocyte proliferation assay evaluates their ability to proliferate in response to a polyclonal stimulation, which is considered to reflect the activation of the immune response after an antigenic stimulation in vivo. No statistically significant relationship was found between the lymphocyte stimulation index and blood pollutants or class of pollutants studied (i.e. mercury, lead, persistent organic pollutants, pentachlorophenol, tribromoanisole) in harbour seals sampled while in good body condition and presenting no sign of disease. However, the number of lymphocytes per milliliter of whole blood appeared to be negatively correlated to pentachlorophenol, an organochlorine pesticide. A high interindividual variability of lymphocyte stimulation indexes was observed although cells were isolated in the same way and cultured in identical conditions. This is probably linked to a whole set of parameters such as precise age, sex, life history leading to particular immune status (probably partly related to pollutant loads), physiological parameters and inevitable experimental variability. So, in a general manner, experiments with in vitro immune cell cultures of wild marine mammals should be designed so as to minimise confounding factors in which case they remain a valuable tool to study pollutant effects in vitro. The second objective of this study was to determine underlying mechanisms of methylmercury immunotoxicity. Indeed, among the numerous contaminants found in harbour seal tissues, methylmercury is one of the most hazardous organic compounds known to have numerous detrimental effects on living organisms. It has the property to bioaccumulate and biomagnify in the trophic chain, and can reach very high levels in harbour seal tissues. Peripheral blood leucocytes exposed to relatively low concentrations of methylmercury chloride (MeHg) in vitro revealed a significant decrease of viable cell counts with obvious ultrastructural effects. A higher frequency of apoptosis was observed in lymphocytes, in which mitochondria and nuclei may have been targeted, as demonstrated by ultrastructural analysis. These results were in accordance with the significant decrease of the mitochondrial membrane potential and of lymphocyte proliferation (BrdU assay) observed. The toxicity of this compound was shown to be counteracted by selenium. However, little is known about that interaction in marine mammal blood and the underlying mechanisms still remain unclear. The present study aimed to investigate the in vitro effects of relatively low (0.75 µM) MeHgCl levels on harbour seal ConA-stimulated leucocytes while added concomitantly to Se. Two different forms of Se were studied: selenite and selenomethionine. Their concentrations were within the range of those measured in free-ranging harbour seal blood, and in a Hg:Se ratio of 1:10. Lymphocyte proliferation as well as the mitochondrial membrane potentials were significantly reduced following in vitro exposure to MeHgCl during 72h. No significant difference was found when sodium selenite or selenomethionine was added concomitantly to MeHgCl. Conversely, on average, Se alone did not lead to significant decreased proliferation and mitochondrial membrane potentials. The absence of protection of Se, either in organic or inorganic form, against Hg toxicity in harbour seal blood leucocytes in vitro raises concern as regards the deleterious effects this toxic compound could have on marine mammal immune system. The range of current Hg levels found in free-ranging harbour seals from the North Sea encompasses exposure levels which elicited deleterious effects on lymphocytes in the present study. This highlights the potential for effects on host resistance to disease. [less ▲]
