Cellular immunodeficiency related to chronic dermatophytosis in a patient with Schistosoma mansoni infection: can schistosomiasis induce immunodeficiency?

Abstract: Here, we describe a case of hepatosplenic schistosomiasis that progressed to widespread persistent dermatophytosis. Significant T and B lymphocytopenia was confirmed. T-cell deficit is associated with increased susceptibility to fungal infections of skin and mucous membranes. The accumulation of a large amount of blood cells in the spleen could have played a crucial role in the development of lymphocytopenia in the present case. Alternatively, the schistosomiasis-induced increase in prostaglandin E2 levels could have inhibited the production of interferon- γ , a cytokine fundamental to fungal resistance. This case shows the potential of hepatosplenic schistosomiasis to impair the immune response.

We present the case of an immunocompetent 55-year-old woman, treated with corticosteroids, developing a cerebral fungal infection with autoptic ascertainment of aspergillosis and mucormycosis. This is the first report of cerebral co-infection by mucorales and aspergillus in an immunocompetent host. A possible explanation is that corticosteroids, even if taken for a short time, led to a transient lowering of immune function and contributed to negative outcome.

ConclusionThere are very limited studies related to the immune modulation status of HIV co-infected with Cryptococcus before the initiation of any drug therapy. Such information might through in-depth light to understand the initial state of the immune environment which certainly would play a pivotal role in the outcome of the immune modulation.

Authors: Gil-Gouveia R, Marto N, Vilela P, Catarino A Abstract Susac syndrome is a rare, probably immune-mediated endotheliopathy presenting with encephalopathy, sensorineural hearing loss and retinal arterial occlusions. A 33-year-old female with Susac syndrome was worsening despite high-dose steroids so a brain biopsy was performed which suggested a possible fungal infection. Treatment with amphotericin B resulted in prompt reversal of symptoms and radiological findings, and no further symptoms occurred during 8 years of follow-up. A diagnosis of fungal infection was not confirmed. The etiolog...

AbstractThe aim of the study was to evaluate antifungal prescriptions among hospitalized adult patients in Greek hospitals. This multicenter two-times, 1-day, point-prevalence study was carried out in 2015 and 2017 in five and six hospitals, respectively. Among the 5812 patients screened in both periods, antifungals were prescribed in 129 patients (73 in 2015 and 56 in 2017); antifungals were used as prophylaxis in 31 patients (24%), pre-emptively in 32 (25%), empirically in 38 (30%), and as targeted therapy in 28 (22%). Triazoles were the class most commonly used (65 patients; 50%), followed by echinocandins (59; 46%) and...

The incidence and prevalence of serious fungal infections is rising, especially in immunosuppressed individuals. Moreover, co-administration of antibiotics and immunosuppressants has driven the emergence of new multidrug-resistant pathogens. The significant increase of multidrug-resistant pathogens, together with their ability to form biofilms, is associated with morbidity and mortality. Research on novel synthetically prepared immunomodulators as potential antifungal immunotherapeutics is of serious interest. Our study demonstrated the immunobiological activity of synthetically prepared biotinylated mannooligosaccharides ...
