Description of Cryptococcosis Following SARS-CoV-2 Infection: A Disease Survey Through the Mycosis Study Group Education and Research Consortium (MSG-19).

BACKGROUND: Invasive fungal infections have been described throughout the COVID-19 pandemic. Cryptococcal disease after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been reported in several isolated case reports and 1 larger case series. We sought to describe cryptococcal infections following SARS-CoV-2 through establishing a database to investigate underlying risk factors, disease manifestations, and outcomes. METHODS: We created a crowdsourced call for cases solicited through the Mycoses Study Group Education and Research Consortium, the Centers for Disease Control and Prevention Emerging Infectious Diseases Network, and infectious diseases Twitter groups. Data were collected in a web-based and secure REDCap survey without personal identifiers. RESULTS: Sixty-nine cases were identified and submitted by 29 separate institutional sites. Cryptococcosis was diagnosed a median of 22 days (interquartile range, 9-42 days) after SARS-CoV-2 infection. Mortality among those with available follow-up was 72% (26/36) for the immunocompetent group and 48% (15/31) for the immunocompromised group (likelihood ratio, 4.01; P = .045). We observed a correlation between disease manifestation (central nervous system infection, proven/probable disseminated disease, and respiratory) and mortality (P = .002). CONCLUSIONS: The mortality rate of 59% for patients with cryptococcosis following SARS-CoV-2 is higher than that of modern Cryptococcus cohorts. There was an association between immunocompromised status and cryptococcal disease manifestations as well as mortality. Moreover, our series emphasizes the need for clinical and laboratory assessment of opportunistic infections beyond 30 days when concerning symptoms develop.

Hepatic Steatosis is Associated with an Increased Risk of Postoperative Infections and Perioperative Transfusion Requirements in Patients Undergoing Hepatectomy.

BACKGROUND: To determine the impact of hepatic steatosis on perioperative outcomes of patients undergoing hepatectomy. METHODS: We analyzed all hepatectomy patients with normal and fatty liver texture, between 2014 and 2018 using NSQIP. Main endpoints included perioperative transfusions (within 72 h) and infectious complications. RESULTS: A total of 8,237 patients underwent hepatectomy during the study period. The overall rate of fatty liver texture (FLG) was 31% (2,557). Operative duration was significantly longer; inflow occlusion was more common (Pringle maneuver), and the need of transfusions was significantly higher in the FLG compared to the normal liver group (NLG) (p = < 0.001). On multivariate analysis, patients in the FLG had increased risk of developing infectious complications (OR 1.22 [95%IC 1.05-1.41]) and transfusion requirements within 72 h after hepatectomy (OR 1.43 [95% CI 1.24-1.63]). CONCLUSIONS: Hepatic steatosis is an independent risk factor for the development of infectious complications and increased perioperative transfusion requirements in patients undergoing hepatectomy. Those requiring transfusions within 72 h had also an increased risk of infections after hepatectomy.

Bartonellosis in transplant recipients: A retrospective single center experience.

BACKGROUND: Bartonellosis is a rare but challenging condition to diagnose with a spectrum of clinical presentations in the immunocompromised host. AIM: To further characterize the presentation of Bartonella henselae (B. henselae) infections in solid organ and hematopoietic stem cell transplant recipients. METHODS: We conducted a single-center retrospective study of all B. henselae testing for 5012 transplant recipients receiving care at a single institution between 2011 and 2018. RESULTS: We identified 38 patients who underwent testing for B. henselae, and three of 38 were found to have bartonellosis. Two of the patients were renal transplant recipients who presented with visceral bartonellosis and symptoms concerning for post-transplant lymphoproliferative disorder. One autologous stem cell transplant recipient presented with cat scratch disease. We detail the clinical courses of these three cases and review the literature concerning the clinical presentations, differential diagnosis, and limitations of diagnostic tests for B. henselae infections in transplant recipients. CONCLUSION: Although the incidence of B. henselae infection in transplant recipients is unknown, it merits inclusion in the differential diagnosis for fever of unknown origin in this population.

Strongyloides Stercoralis Infection Among Human Immunodeficiency Virus (HIV)-Infected Patients in the United States of America: A Case Report and Review of Literature.

BACKGROUND Strongyloides stercoralis infection is endemic in subtropical and tropical regions but is reported rather sporadically in temperate countries. In the USA, the highest rates of infection are from the southeastern states, predominantly among immigrants. There is paucity of case reports on S. stercoralis infection among HIV-infected patients who were born and raised in the USA. CASE REPORT A 61-year-old male with known HIV infection (CD4 count: 235 cells/uL, undetectable HIV RNA, on antiretroviral therapy) presented with a 3-month history of diarrhea. He was initially diagnosed to have diarrhea secondary to norovirus and later with Escherichia coli. He was treated with levofloxacin but the diarrhea persisted. Stool PCR, Clostridium difficile enzyme-linked immunoassay, cryptosporidium and giardia antigen, cyclospora and isospora smear, and fecal microscopy were all negative. Peripheral blood eosinophil count was 1,000 eosinophils/mcL. Colonic biopsies revealed fragments of S. stercoralis larvae within the crypts. The patient was treated with ivermectin with improvement of symptoms. Social history revealed that he was born and raised in the northeastern USA. He was a daily methamphetamine user and engaged in anal sex with men. He denied travel to endemic areas, except for a visit to Japan more than 30 years ago. CONCLUSIONS Our case highlights that S. stercoralis may be an underdiagnosed/under-reported cause of chronic diarrhea among HIV-infected patients. What makes this case peculiar is that the patient was born and raised in the continental USA, absence of recent travel to endemic areas, and relatively high CD4 counts. Parasitic infections, such as S. stercoralis, should be considered among HIV-infected patients with persistent diarrhea and eosinophilia regardless of ethnicity or recent travel history.
