Aspergilloma and Marijuana Smoking
Smoking (tobacco and marijuana) is commonly associated with the formation of air filled lung cavities (bullae) but this is the first report of these cavities containing fungal balls (aspergilloma) and of CPA in marijuana smokers. An understanding of the full health risk in smoking marjuana is difficult to assess since the lack of disclosure by patients of their smoking habits - for fear of legal issues - does not permit clinicians to fully assess the results of smoking this drug. Latest News and ArticlesThe Fungal Research Trust is 20 years old this year and are in the early stages of planning a meeting in London on 18th June 2011 to celebrate this anniversary. The meeting will include the first meeting for patients in London. More details to follow when available. Reports from Mumbai, India found that 15-20% of all patients suffering from breathing difficulties during a recent period prolonged of heavy smog. Authorities blame the prevailing weather conditions which have been cool but humid (ideal for fungal growth) combined with record levels of particulates (dust, soot, spores etc.) over the last 5 days. Patients who did not respond to standard treatment were tested for fungal infection. Articles: There have been 80 additions to the Articles section (76 full papers), of which 11 are reviews and 14 historical. We have picked out a few of the highlights here: Selective C-Rel Activation via Malt1 Controls Anti-Fungal T(H)-17 Immunity by Dectin-1 and Dectin-2 and Dectin-1 diversifies Aspergillus fumigatus-specific T cell responses by inhibiting T helper type 1 CD4 T cell differentiation Two papers that add a further piece each to the jigsaw of immune response to infection by Aspergillus. The first paper identifies Malt1 as a key intermediate in the activation of adaptive immunity to fungi by dendritic cells via c-Rel. The second paper uses a mouse knockout strain lacking Dectin-1 to demonstrate the changes to the mutant compared with wild-type immune reponse when challenged with Aspergillus fumigatus pulmonary infection. Dectin-1 is the major receptor in myeloid cells (part of our immune system) for the fungal cell wall component b-Glucan. It is this protein that directly recognises the presence of a fungus and initiates our immune system's response. The gene for Dectin-1 has many naturally ocurring variations in its sequence (polymorphism) and it has been observed that the polymorphism named Y238X which occurs in humans susceptible to fungal infection. This paper set out to test if patients that carry Y238X are more susceptible to fungal infection during a bone marrow transplant procedure. The surprising result was that they didn't seem to be more susceptible. Comparative genomics allowed the identification of drug targets against human fungal pathogens Genomic sequencing of all organisms is now relatively quick & cheap and as a consequence is being performed on many different fungal species and strains. Comparing the DNA sequences of these fungi reveals which genes are present in all fungi and thus by inference which genes are most important to the fungus. These genes are thus amongst the most highly prized target to develop drugs to kill the fungus. Stop any one of them working and the fungus is not likely to survive. Septins have a well established role in the development of fungal septa - the cell walls that separate one fungal cell compartment from another. This family of genes have never been studied in detail in Aspergillus fumigatus. This paper looks at the localisation of septins in the fungal hyphae and finds that septins may have a role in pathogenicity. ReviewsUpdate on the laboratory diagnosis of invasive fungal infections An assessment of the newer diagnostic techniques for the detection of invasive aspergillosis. Management of invasive fungal infections: a role for polyenes This older class of antifungal drug can receive less attention now we have the choice of several effective new drugs for the treatment of invasive fungal infections (IFI's) e.g. azoles, but polyenes are still very effective and the drug of choice in some circumstances. This review highlights important issues in the treatment of IFI's for consideration by clinicians.

Help the National Aspergillosis Centre carry out research. We are trying to contact patients willing to try to get their GP practice involved in some research with us on prevelence of ABPA and SAFS - we need details of respiration function of all asthma patients. The GP practice must be within 2 hours drive of Manchester. All you will have to do is hand over our documentation to the practice which will explain everything.

Our novel approach for fungal species diagnostics combines fluorescent staining of mounted cryosections with the optical brightener Blankophor, laser capture microdissection and PCR amplification with subsequent sequencing of the first internal transcribed spacer region (ITS-1). Using clinical specimens from infected birds, we show that the procedure is suitable for species identification from single hyphae of intralesional filamentous fungi. Our data also suggest that multiple Aspergillus fumigatus strain infections may occur frequently in pulmonary aspergillosis of birds.
