Objectives: The characteristics of patients with Acute Respiratory Distress Syndrome (ARDS) as a complication of Babesia microti infection have not been systematically described.Methods: Adult patients admitted to the medical intensive care unit (MICU) of a tertiary care hospital in the Lower Hudson Valley of New York from 1/1/2008 to 8/1/2016 were evaluated for ARDS complicating babesiosis.Results: Of 22 patients with babesiosis in the MICU, eight (36.4%; 95% CI: 19.7-57.0%) had ARDS. Six patients (75%) developed ARDS following initiation of anti-babesia drug therapy; however, the mean duration of symptoms in these patients exceeded that of patients who developed ARDS prior to initiation of treatment (7.50 ± 3.83d vs. 4.50 ± 0.71d, p = 0.34). Three patients (37.5%; 95% CI: 13.7-69.4%) expired without recovery from ARDS. In comparison, the mortality rate for the 14 MICU babesiosis patients without ARDS was 14.3% (p = 0.31). There was a trend toward younger age in survivors relative to non-survivors (mean age 54.6 ± 13.8y vs. 74.0 ± 6.24y, p = 0.07). Three of the five survivors did not require mechanical ventilation. The mean sequential organ failure assessment score of non-survivors was significantly higher than that of survivors (12.3 ± 1.15 vs. 6.0 ± 1.4, p = 0.0006).Conclusion: Among 22 critically ill adult patients with B. microti infection, ARDS developed in eight (35.4%), and three (37.5%) expired without resolution of the ARDS. ARDS often followed the initiation of anti-babesia drug therapy, raising the question of whether the death of the parasite per se contributed to its development. However, this observation was confounded by the longer duration of symptoms preceding initiation of drug therapy. [ABSTRACT FROM AUTHOR]

Background: The Centers for Disease Control and Prevention and New York State Department of Health recently identified the Capital District of New York (CDNY) as an emerging endemic area for blastomycosis. However, no clinical or epidemiological description of blastomycosis in the CDNY has been published.Methods: We performed a retrospective analysis of blastomycosis cases at Albany Medical Center (AMC) and Albany Stratton Veterans Affairs Medical Center (VAMC) from January 1, 2000, through June 1, 2019. Patients were identified via an institution-approved informatics system at the hospital's microbiology laboratory.Results: We identified 20 patients diagnosed with blastomycosis over the past 2 decades. There was a nearly 9-fold increase in the annual number of cases in 2016-2019 compared with 2000-2015. The majority of patients resided in the CDNY (90%), and 65% lived within the Mohawk River valley. Most cases (85%) were assumed to be malignancies or non-mycotic infections prior to diagnosis, with median time between presentation and diagnosis of 53 days.Conclusions: Our data support recent reports that blastomycosis is an emerging disease in the CDNY. Most patients were misdiagnosed as malignancy or non-mycotic infection, which led to treatment delays. [ABSTRACT FROM AUTHOR]
