The expression "immunocompromised host" refers to an individual who has one or more defects in the body's natural defense, which leads to severe, often life-threatening, infections. Alcoholism, diabetes mellitus, advanced age, the use of antacids, and viral infections have immune-modulating effects. The human immunodeficiency virus, cytomegalovirus, Epstein-Barr virus, and Non A, Non B hepatitis virus also contribute to immunosuppression. The lung has a special vulnerability to infection, and pneumonia accounts for more than 40% of deaths in the immunosuppressed population. Diagnostic methods include detection of microbial antigens by monoclonal antibodies, DNA sequences by the polymerase chain-reactions or DNA probes, and unique metabolites of pathogens by gas chromatography. Transtracheal aspiration was used to obtain uncontaminated respiratory secretions, but fiberoptic bronchoscopy with shielded brush and bronchoalveolar lavage (BAL) is a better means of diagnosis because of a 90% sensitivity in diagnosing pneumocystis infection. Percutaneous aspiration and open lung biopsy are reserved for more complicated cases. Empiric treatment is justified in far advanced AIDS or relapsed myelogenous leukemia with limited life expectancy, or when there is uncontrollable bleeding diathesis or impaired pulmonary function as invasion diagnostic procedures will not be tolerated. The most important antiinfective measure is careful hand washing, while prophylactic antibiotics, selective decontamination, and antifungal, antiviral, and antiparasitic agents can be used. Active and passive immunization against specific pathogens, immunological reconstitution with granulocyte-macrophage colony-stimulating factor (GM-CSF) and reducing the dosage of immunosuppression are the other strategies for prevention. In the last several decades there has been substantial progress in the management of chronic diseases which used to be fatal.

We recently reported the anti-hepatitis effect of a polysaccharide, designated as the D-fraction, extracted from maitake. Its effect includes immuno-regulating activities. We investigated the effect of the glucan in collagen-induced arthritis (CIA). The D-fraction was administered to CIA mice for 30 consecutive days. Arthritis development was observed from the 4th day after the second immunization. The D-fraction did not have any influence on anti-type II collagen antibodies in blood serum or activated B cells. To determine how cellular immunity may be involved in the development of CIA, ratios of CD4+ T cells and their activated form in the axillary and inguinal lymph node T cells were detected by flow cytometry analysis. The ratios were not different between the D-fraction group and the control group. However, interleukin-1beta, granulocyte-macrophage colony-stimulating factor and tumor necrosis factor-alpha productions from splenic macrophages were significantly increased to 2.0, 4.7 and 1.9 times the control group level, respectively. The ratio of macrophages in the whole spleen cells was 2.3 times that of the control group, and their migrating ability was 1.9 times higher. Based on these results, we concluded that the arthritis development induced by D-fraction administration is attributable to the activation of splenic macrophages.

We report the first case of hepatitis due to Aspergillus terreus in a 13-year-old boy with common variable immunodeficiency that occurred while the patient was receiving secondary prophylaxis with fluconazole after an episode of pulmonary candidosis. The infection subsided after the addition of itraconazole to the combination of liposomal amphotericin B and granulocyte-macrophage colony-stimulating factor that he was receiving.
