Despite the refinements in molecular methods for the detection of cytomegalovirus (CMV) and the advent of highly effective preemptive strategies, CMV remains a leading cause of morbidity and mortality in hematopoietic cell transplant (HCT) recipients. CMV can cause tissue-invasive disease including pneumonia, hepatitis, colitis, retinitis, and encephalitis. Mortality in HCT recipients with CMV disease can be as high as 60%. CMV infection has been associated with increased risk of secondary bacterial and fungal infections, increased risk of graft-versus-host disease, and high rates of nonrelapse mortality following HCT...

Infectious diseases have serious impacts on human and wildlife populations, but the effects of a disease can vary, even among individuals or populations of the same host species. Identifying the reasons for this variation is key to understanding disease dynamics and mitigating infectious disease impacts, but disentangling cause and correlation during natural outbreaks is extremely challenging. This study aims to understand associations between symbiotic bacterial communities and an infectious disease, and examines multiple host populations before or after pathogen invasion to infer likely causal links...

Ali S Omrani, Reem S Almaghrabi
Patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are at increased risk of invasive fungal infections, especially during the early neutropenic phase and severe graft-versus-host disease. Mold-active prophylaxis should be limited to the highest risk groups. Empiric antifungal therapy for HSCT with persistent febrile neutropenia is associated with unacceptable response rates, unnecessary antifungal therapy, increased risk of toxicity, and inflated costs. Empiric therapy should not be a substitute for detailed work up to identify the cause of fever in such patients...

Functional endoscopic sinus surgery (FESS) has considerably evolved over the past 20 years while minimally-invasive surgery also applies to sinus procedures. Development of new technologies combined with better knowledge of risks has allowed surgeons to achieve improved results in their FESS indications. One of the most difficult areas to visualize using the exclusive endoscopic approach is still the anterior recess of the maxillary sinus. Hence, external approaches, such as the Caldwell-Luc procedure, are still used by many surgeons to ensure visual control of this area in diseases such as fungal balls, mucoceles, inverted papilloma and other tumors...

β-(1,3)-d-glucan (BDG) is used to rule out invasive fungal disease (IFD) but its usefulness in cystic fibrosis (CF) has not been evaluated. We measured serum BDG in CF patients with no clinical suspicion of IFD. Samples from 46 adult CF patients during a stable period and during pulmonary exacerbation were tested. The association of BDG with clinical variables was analyzed. Three hundred and three non-CF patients with suspected IFD were used as comparators. Both samples were negative in 52% of CF patients, whereas 67% of comparators had only negative results (P=0...

Invasive fungal and fungal-like infections contribute to substantial morbidity and mortality in immunocompromised individuals. The incidence of these infections is increasing-largely because of rising numbers of immunocompromised patients, including those with neutropenia, human immunodeficiency virus, chronic immunosuppression, indwelling prostheses, burns, and diabetes mellitus, and those taking broad-spectrum antibiotics. Invasive fungal pathogens include primary mycotic organisms such as Histoplasma capsulatum, Coccidioides immitis, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, which are true pathogens and inherently virulent...

The widespread implementation of immunosuppressants, immunomodulators, hematopoietic stem cell transplantation and solid organ transplantation in clinical practice has led to an expanding population of patients who are at risk for invasive candidiasis, which is the most common form of fungal disease among hospitalized patients in the developed world. The emergence of drug-resistant Candida spp. has added to the morbidity associated with invasive candidiasis and novel therapeutic strategies are urgently needed...

Aspergillus fumigatus is an opportunistic fungal pathogen that causes invasive aspergillosis (IA), a life-threatening disease in immunocompromised humans. The echinocandin caspofungin, adopted as a second-line therapy in combating IA, is a β-1,3-glucan synthase inhibitor, which, when used in high concentrations, reverts the anticipated A. fumigatus growth inhibition, a phenomenon called the "caspofungin paradoxical effect" (CPE). The CPE has been widely associated with increased chitin content in the cell wall due to a compensatory upregulation of chitin synthase-encoding genes...

Myeloid sarcoma is a rare malignant extramedullary neoplasm of myeloid precursor cells. The majority of these cases occur in patients with known leukemia or those who eventually develop the disease. It can occur in various sites but sinonasal cavity involvement along with invasive fungal infection is exceedingly rare.

Candida albicans is a ubiquitous mucosal commensal that is normally prevented from causing acute or chronic invasive disease. Neutrophils contribute to protection in oral infection but exacerbate vulvovaginal candidiasis. To dissect the role of neutrophils during mucosal candidiasis we took advantage of a new, transparent zebrafish swimbladder infection model. Intravital microscopic tracking of individual animals revealed that blocking neutrophil recruitment leads to rapid mortality in this model through faster disease progression...

WHAT IS KNOWN AND OBJECTIVE: Bacterial infections are the leading causes of morbidity and mortality in haematologic patients with chemotherapy-induced neutropenia. The only strategy shown to be effective in reducing febrile neutropenia incidence is fluoroquinolone prophylaxis, but the safety of this class of drugs in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD-), the most common human enzyme defect, is still controversial because of the claimed association with acute haemolytic anaemia...

WHAT IS KNOWN AND OBJECTIVES: Triazoles including fluconazole, itraconazole, voriconazole and posaconazole are now widely used, whereas in some countries, they are reportedly used in inappropriate way frequently; thus, it is clearly a matter of urgency to regulate the use of triazole drugs. Several studies have made good attempts to evaluate antifungal use, but they did not cover the entire medication process. This study aimed to establish indicators for the appropriate use of triazoles for invasive fungal disease, so as to produce a reference for evaluating and standardizing the rational application of triazole antifungals...

The devastating bat fungal disease, white-nose syndrome (WNS), does not appear to affect all species equally. To experimentally determine susceptibility differences between species, we exposed hibernating naïve little brown myotis (Myotis lucifugus) and big brown bats (Eptesicus fuscus) to the fungus that causes WNS, Pseudogymnoascus destructans (Pd). After hibernating under identical conditions, Pd lesions were significantly more prevalent and more severe in little brown myotis. This species difference in pathology correlates with susceptibility to WNS in the wild and suggests that survival is related to different host physiological responses...

Invasive fungal disease(IFD) is a common yet highly lethal complication in patients with hematological malignancies receiving chemotherapy or stem cell transplantation, as well as immune suppressive conditions including aplastic anemia and other malignancies. According to the diagnostic criteria, patients are defined as proven, probable, possible and undefined IFD based on the evidence provided by histopathologic/cytologic, culture, radiographic and biomarker examinations. For the management of IFD, the major treatment strategies consist of prophylaxis, empirical, diagnostic-driven and target therapy...

Cryptococcosis is a major invasive fungal disease related worldwide with the AIDS population. New reports of HIV/AIDS cases to the national public health surveillance system (SIVIGILA) in Colombia have shown that there is a growing community at risk of contracting cryptococcosis throughout the country who do not have access to ART. Even though the most prevalent species Cryptococcus neoformans is mainly associated with the HIV population, we report a fatal case of cryptococcosis in an AIDS patient in Barranquilla, associated with Cryptococcus gattii VGI, isolated from blood culture...
