Reported cases suggest emotional stress reactions as the most common inciting events. The pathogenesis of the condition is not well understood. We describe a 9-year old boy and his 6-month old half-sister with a history of bleeding episodes from the ears, eyes, and scalp, as well as other sites. Symptoms in both children have shown a positive response to propranolol, with decreased frequency and severity of bleeding. There are no prior reports of siblings with hematohidrosis, suggesting a possible genetic predisposition. / Revisión por pares

Previous studies of the ontogeny of the mucosal immune system have shown a significant increase in salivary Immunoglobulin A levels occurring at about five years of age. This study has monitored a group of 3 and 4 year old children during one year of attendance at Pre-School to examine whether such an increase could be linked to increased antigenic exposure associated with moving into a school like environment. Saliva samples were collected at regular intervals and analysed for immunoglobulin and total protein levels. Daily health records were maintained for each child, and a detailed social and medical history was collected for each child at the beginning of the study. The elevated mucosal immune response observed in previous studies involving children in day care centres and attending school was not seen in this study. No significant difference was observed between children who had previously attended Pre-School or child care centres and those who were attending for the first time. However, a marked seasonal increase in mean salivary IgA during the winter months was observed and this increase correlated with an increase in respiratory infections. Hence, in studies of developmental aspects of mucosal immune response it is essential that modifiers such as season and infection be recorded.

The immense global tuberculosis (TB) burden highlights the shortcomings of current vaccination and antibiotic regimens. Novel prophylactic TB vaccines that can either boost or replace BCG entirely remains an active area of research. Additionally, the success of current antibiotic therapies against TB is hindered by their complexity and duration, with large percentages of patients failing to complete treatment. Multi-armed approaches are required to properly and efficiently combat diseases. Besides prophylactic vaccines, development of therapeutic vaccine strategies as an adjunct to antibiotic treatment would represent another major step in TB control. To achieve such a goal, vaccines must consider the pathogen’s life cycle, the immunological responses which they drive, and the populations in which they will ultimately be administered. As such, the purpose of this dissertation is to utilize state-of-the-art molecular cloning techniques to construct novel chimpanzee adenovirus-vectored vaccines that provide prophylactic and therapeutic immunity against pulmonary TB. By considering different phases of the pathogen’s life cycle, we aim to select a collection of antigens that are protective, regardless of disease state. Development of such platforms would lay and bolster the groundwork for improved vaccine strategies against TB. / Dissertation / Doctor of Philosophy (PhD)
