RESUMEN

A 67 year-old male was admitted in the ICU because of multi-organ failure due to sepsis secondary to Fournier's gangrene. He had sustained radical prostatectomy in the last 48 hours. Peritoneal fluid and fatty tissue biopsies grew Aspergillus Fumigatus without concomitant pulmonary involvement. Postoperative acquisition via exogenous and endogenous routes is discussed, as this nosocomial entity is very rarely reported apart from peritoneal dialysis, especially in non-immunosuppressed patients.

RESUMEN

BACKGROUND: Fungal infections, during or as a consequence of SARS-CoV-2 infection, associated with uncontrolled diabetes mellitus and indiscriminate use of corticosteroids have been reported. In the jaw, mostly mucormycosis has been diagnosed in hospitals. METHODS: A retrospective, cross-sectional, descriptive study of the clinical, imaging, and histopathologic characteristics of maxillary invasive fungal infection in post-COVID-19 patients diagnosed in a private non-hospital oral pathology service in Mexico during 2020-2022 was conducted. RESULTS: We found 20 cases of maxillary invasive fungal infections in post-COVID-19 patients, 75% including a diagnosis of mucormycosis and 25% diagnosed as probable aspergillosis. The most common signs and symptoms were exposed necrotic bone followed by tooth mobility, discharge, and pain. On imaging, unilateral maxillary sinus involvement was observed in 6 cases (30%), and bilateral maxillary sinus involvement was observed in 3 cases (15%). CONCLUSIONS: It is essential to consider the association of osteonecrosis of the jaw in post-COVID-19 patients, with aspergillosis, not only mucormycosis, for early diagnosis and appropriate treatment.

RESUMEN

BACKGROUND: Viral pneumonia such as COVID-19-associated aspergillosis could increase susceptibility to fungal super-infections in critically ill patients. METHODS: Here we report a pediatric case of Aspergillus quadrilineatus cerebral infection in a recently diagnosed COVID-19-positive patient underlying acute lymphocytic leukemia. Morphological, molecular methods, and sequencing were used to identify this emerging species. RESULTS: Histopathological examination showed a granulomatous necrotic area containing dichotomously branching septate hyphae indicating a presumptive Aspergillus structure. The species-level identity of isolate growing on brain biopsy culture was confirmed by PCR sequencing of the ß-tubulin gene as A. quadrilineatus. Using the CLSI M38-A3 broth microdilution methodology, the in vitro antifungal susceptibility testing demonstrated 0.032 µg/mL MIC for posaconazole, caspofungin, and anidulafungin and 8 µg/mL against amphotericin B. A combination of intravenous liposomal amphotericin B and caspofungin therapy for 8 days did not improve the patient's condition. The patient gradually continued to deteriorate and expired. CONCLUSIONS: This is the first COVID-19-associated cerebral aspergillosis due to A. quadrilineatus in a pediatric patient with acute lymphocytic leukemia. However, comprehensive screening studies are highly recommended to evaluate its frequency and antifungal susceptibility profiles. Before being recommended as first-line therapy in high-risk patients, more antifungal susceptibility data are needed.

RESUMEN

Infection by Aspergillus covers a broad clinical spectrum, including invasive pulmonary aspergillosis (IPA) and its disseminated extrapulmonary form, invasive aspergillosis (IA). It typically occurs in severely immunocompromised hosts, but it sometimes affects the immunocompetent population, especially patients with acute diseases being treated at the intensive care unit (ICU) and less often those with chronic conditions. In this article, we report the case of a 50-year-old male, with diabetes mellitus (DM) as the only risk factor, treated for IPA and IA with cardiac and central nervous system (CNS) involvement at a high complexity institution in Cali-Colombia. Clinical presentation and radiological findings are unspecific and require a high level of suspicion. To confirm the case, histological or cytological of the fungus is required; histopathological examination of lung tissue is the gold standard, but it is difficult to perform due to respiratory compromise and high risk of bleeding, so bronchoscopy and bronchoalveolar lavage (BAL) plays an essential role in the diagnostic process. A diagnostic algorithm that includes risk assessment, symptoms, imaging findings, and isolation in cultures is essential to allow the diagnosis and initiation of treatment promptly, which includes a combination of surgery and antifungal medications for long periods, even life-long treatment.

RESUMEN

Cytomegalovirus (CMV) and invasive aspergillosis (IA) cause morbidity among lung transplant recipients (LTXr). Early diagnosis and treatment could improve outcomes. We examined rates of CMV after IA and vice versa to assess whether screening for one infection is warranted after detecting the other. All Danish LTXr, 2010-2019, were followed for IA and CMV for 2 years after transplantation. IA was defined using ISHLT criteria. Adjusted incidence rate ratios (aIRR) were estimated by Poisson regression adjusted for time after transplantation. We included 295 LTXr, among whom CMV and IA were diagnosed in 128 (43%) and 48 (16%). The risk of CMV was high the first 3 months after IA, IR 98/100 person-years of follow-up (95% CI 47-206). The risk of IA was significantly increased in the first 3 months after CMV, aIRR 2.91 (95% CI 1.32-6.44). Numbers needed to screen to diagnose one case of CMV after IA, and one case of IA after CMV was approximately seven and eight, respectively. Systematic screening for CMV following diagnosis of IA, and vice versa, may improve timeliness of diagnosis and outcomes for LTXr.

RESUMEN

BACKGROUND: Kidney transplant recipients are at increased risk for invasive aspergillosis (IA), a disease with poor outcomes and substantial economic burden. We aimed to determine risk factors for posttransplant IA by using a national database and to assess the association of IA with mortality and allograft failure. METHODS: Using the United States Renal Data System database, we performed a retrospective case-control study of patients who underwent kidney transplant from 1998 through 2017. To evaluate risk factors for IA, we performed conditional logistic regression analysis by comparing characteristics between IA-infected patients and their matched uninfected controls. We performed Cox regression analysis to evaluate the effects of IA on mortality and death-censored allograft failure. RESULTS: We matched 359 patients with IA to 1436 uninfected controls (1:4). IA was diagnosed at a median of 22.5 months (interquartile range, 5.4-85.2 months) after kidney transplant. Risk factors for IA were Black/African American race, duration of pretransplant hemodialysis, higher Elixhauser Comorbidity Index score, weight loss, chronic pulmonary disease, need for early posttransplant hemodialysis, and a history of cytomegalovirus infection. Receiving an allograft from a living donor was protective against IA. IA was a strong independent predictor of 1-year mortality (adjusted hazard ratio [aHR], 5.02 [95% confidence interval {CI}, 3.58-7.04], P < .001). Additionally, IA was associated with 1-year allograft failure (aHR, 3.37 [95% CI, 1.96-5.77], P < .001). CONCLUSIONS: Our findings emphasize the importance of timely transplant to mitigate the risk of posttransplant IA. An individualized approach to disease prevention is essential to decrease mortality and allograft failure.

RESUMEN

Mucocutaneous mycotic infections are common complications in patients on IL-17 inhibitor therapy. We report a case of a 33-year-old male with severe psoriasis and psoriatic arthritis on secukinumab combined with methotrexate and prednisone with swelling, otorrhea, and pain of the right ear and external auditory canal. Due to progressive hypacusis, a surgical solution was chosen. Tissue samples taken during surgery revealed the presence of Aspergillus fumigatus. Aspergillosis should be suspected in prolonged otorrhea, especially in immunocompromised patients. Without intervention, the disease could be fatal.

RESUMEN

Aspergillosis is a rare and life-threatening fungal infection in immunocompetent children, particularly in infants. We present a case of invasive Aspergillosis (IA) that developed hepatic and mesh infection due to Aspergillus flavus following the rupture of a giant omphalocele. A male baby was born at 37 weeks of gestation with a giant omphalocele. No other congenital abnormalities were found. In the pediatric surgery operation room, the amniotic membrane seemed to be ruptured in some parts, which had been repaired within a few hours of birth. No further intervention to reduce the volume of visceral organs could be performed due to the tiny abdominal cavity. Postoperatively piperacillin-tazobactam and fluconazole were empirically initiated. Abdominal defects had been covered with polypropylene polylactic acid synthetic Mesh on postnatal day 11 to protect the organs and prevent abdominal infections. Fungal hepatic lesions were observed during surgery, and black necrotic lesions were also observed on the mesh on day 12. On the 16th postnatal day, Aspergillus flavus grew in the wound, graft, hepatic biopsy cultures. Serum galactomannan (GM) assay test was positive (GM:2.9), and voriconazole was initiated. All necrotic lesions resolved with liposomal amphotericin B (L-AmB) and voriconazole treatment, and antifungal therapy was discontinued after 134 days. Eye examination for the retinopathy didn't show any abnormalities. The patient was discharged with full recovery on day 155. In conclusion, IA is a rare and life-threatening infection in the neonatal period. To the best of our knowledge, this is the first case of hepatic and mesh infection caused by Aspergillus flavus that was successfully treated with voriconazole and l-AmB.

RESUMEN

INTRODUCTION: Invasive Aspergillus infection (IA) in lung transplantation can result in poor outcomes. Itraconazole has been shown to be effective for fungal prophylaxis in lung transplant recipients. However, IA remains a major cause of death after lung transplantation. Therefore, we aimed to clarify the risk factors for IA on itraconazole prophylaxis. METHODS: We examined 120 recipients to uncover their IA epidemiology, clinical characteristics, and outcomes. In addition, a case-control study was performed to identify risk factors of IA. RESULTS: Of the 120 patients, 12 developed IA under itraconazole prophylaxis. The patient demographics and clinical characteristics were compared among the following two groups: IA group, 12 patients, and control group, 108 patients. Significant differences were observed in age (p = 0.004), history of interstitial pneumonia (p = 0.032), and CMV infection (p < 0.001) between the groups. Before the onset of IA, 92% (11/12) of the patients received itraconazole with trough concentrations above the therapeutic range. IA developed at 272.9 ± 114.1 days after lung transplantation. Of the 12 patients who developed IA, 66.7% (8/12) had early cessation of cytomegalovirus (CMV) prophylaxis due to toxicity of valganciclovir, as follows: leukocytopenia in 4 patients, and renal dysfunction in 4 patients. Of the 8 patients who stopped valganciclovir, 75% (6/8) developed CMV infection subsequently. CONCLUSION: This study suggests that older age, history of interstitial pneumonia, and CMV infection may be important risk factors for IA on itraconazole prophylaxis. These results may help clinicians optimize prophylactic strategies for IA.

RESUMEN

PURPOSE: To report a case of infectious necrotizing scleritis secondary to Aspergillus terreus after intravitreal injection therapy. METHODS: This is a case report with literature review. RESULTS: A 98-year-old woman receiving intravitreal aflibercept injections for neovascular age-related macular degeneration in the left eye presented with severe pain, redness, and purulent discharge at the injection site. She was initially treated with topical fortified antibiotics, and clinical improvement was achieved, although microbial cultures showed negative results. Two months later, she presented with severe ocular pain and was diagnosed with anterior necrotizing scleritis. Scleral scrapings were collected for cultures, and intensive topical antibiotic therapy was reintroduced. Evaluation for autoimmune etiology and microbiological testing showed negative results. Because of the progression of the scleral necrotic area, empirical therapy with topical voriconazole was initiated, and surgical debridement was performed. Finally, the culture was positive for A. terreus. The modified therapy consisted of topical voriconazole and oral voriconazole for 3 months with an excellent clinical outcome. CONCLUSIONS: To our knowledge, this is the first case of fungal necrotizing scleritis secondary to intravitreal injection. Diagnosis was delayed due to its chronic clinical course and the slow fungal growth in culture media, but the combined medical and surgical approach resulted in a satisfactory outcome.

RESUMEN

There is a matter of debate about the clinical impact of cytomegalovirus (CMV) reactivation on the development of late-onset invasive aspergillosis (IA), which occurs 40 days or later after allogeneic hematopoietic stem cell transplantation (HSCT). Using a Japanese transplant registry database, we analyzed the risk factors for the development of late-onset IA in 21,015 patients who underwent their first allogeneic HSCT between 2006 and 2017. CMV reactivation was defined as the initiation of preemptive anti-CMV antiviral therapy. Overall, there were 582 cases of late-onset IA, which occurred at a median of 95 days after HSCT. The 2-year cumulative incidence was 3.4% (95% confidence interval (CI), 3.0-3.9) in patients with CMV reactivation within 40 days after HSCT and 2.5% (95% CI, 2.3-2.8) in those without it (P < 0.001). In a multivariate analysis, CMV reactivation as a time-dependent covariate was significantly associated with the development of late-onset IA (hazard ratio (HR) 1.40, P < 0.001), as well as grade II-IV acute GVHD, age > 50 and HCT-CI ≥ 3 in the entire cohort. If we focus on the subgroup without grade II-IV acute GVHD, which is generally an indication for systemic corticosteroid therapy (n = 12,622), CMV reactivation was still a significant factor for the development of late-onset IA (HR 1.37, P = 0.045) as well as age > 50 years, HCT-CI ≥ 3, and cord blood transplantation. In conclusion, CMV reactivation was associated with an increased risk of late-onset IA after allogeneic HSCT independently of acute GVHD. Close monitoring for late-onset IA is necessary for patients who develop CMV reactivation even without grade II-IV acute GVHD.
