RESUMEN
A 54-year-old male with chronic pancreatitis presented with dyspnea. Computed tomography scans demonstrated a subdiaphragmatic fluid collection with pericardial fistulization. Pericardial fluid cultures were polymicrobial in nature. Purulent pericarditis is rare but carries a high mortality rate. We present the first documented case of pancreatico-pericardial fistulization causing purulent pericarditis.
RESUMEN
Here, we present the case of a 55-year-old male with HIV and persistent lymphopenia who developed a paroxysmal severe cough for over three weeks. Microbiology studies were positive for abundant colonies of Bordetella bronchiseptica. He reports that his dog was also ill with a severe cough, suggesting a possible canine-to-human transmission. This zoonosis has been increasingly recognized and possesses significant morbidity and mortality, especially in immunocompromised hosts.
RESUMEN
COVID-19 can cause serious illness requiring multimodal treatment and is associated with secondary infections. Studies have suggested an increased risk of fungal infections, including candidemia following severe COVID-19 though understanding of risk factors and clinical outcomes remains unclear. OBJECTIVES: To describe clinical characteristics, outcomes and risk factors of candidemia among patients hospitalized with severe COVID-19. DESIGN SETTING AND PARTICIPANTS: A multicenter, case-control study of patients with severe COVID-19 was conducted to evaluate risk factors and clinical outcomes in patients who developed candidemia between August 2020 and August 2021. MAIN OUTCOMES AND MEASURES: Chart review evaluating institutional and patient demographics, clinical and mycological characteristics, concomitant interventions (antibiotics, immunosuppressive agents, parenteral nutrition, degree of oxygen support, mechanical ventilation, surgery), treatment regimens, and outcomes (length of stay and discharge disposition). RESULTS: A total of 275 patients were enrolled in the study, including 91 patients with severe COVID-19 and subsequent candidemia and 184 with severe COVID-19 without candidemia. Most patients received antibiotics prior to candidemia episode (93%), while approximately one-quarter of patients received biologic for COVID-19. In-hospital mortality was significantly higher in the cases compared with the controls (68% vs 40%; p < 0.01). Candida albicans was the most common (53%), followed by C. glabrata (19%). Use of central lines, biologic, and paralytics were independent risk factors for candidemia. CONCLUSIONS AND RELEVANCE: Candidemia following COVID-19 infection is a concern that requires clinical consideration and patient monitoring. Risk factors for the development of candidemia in the setting of COVID-19 infection are largely consistent with traditional risk factors for candidemia in hospitalized patients.
RESUMEN
Here we present a rare case of Clostridium paraputrificum bacteremia in the setting of presumptive complicated appendicitis. The patient was an elderly male who presented in respiratory failure secondary to a suspected aspiration pneumonia. A blood culture result for C. paraputrificum guided the investigation toward an abdominal source of infection as this uncommon isolate has been reported as a gastrointestinal species. He was treated with ampicillin-sulbactam while in the hospital and discharged with metronidazole along with a planned appendectomy as an outpatient. There is no tissue histopathology to date to confirm the presumptive likely diagnosis of complicated appendicitis found on abdominal imaging.
RESUMEN
Brevibacterium is a large genus that is not often involved in pathogenesis, however, since 1991 there have been several case reports of Brevibacterium-associated illness, most often due to bacteremia in the setting of an immunocompromised patient with a central venous catheter (CVC). Here we detail the case of an elderly woman with many comorbidities and a peripherally inserted central catheter (PICC) line for over four years, who presented with septic shock and Brevibacterium bacteremia. In nearly all previous cases of Brevibacterium bacteremia it was thought to be due to a CVC which was removed as part of the treatment in conjunction with antibiotics. In this case, the patient was treated with empiric antibiotics and her blood cultures cleared within 48 hours without catheter removal or antibiotic-lock therapy. The clinical outcome was favorable at 50 days follow-up.
RESUMEN
HIV transmission via solid organ transplant is a rare but serious complication. Here, we describe long-term outcomes in a case of living donor-derived transmission of HIV in a kidney transplant recipient. After 11 years since transplant surgery, the donor shows no evidence of abnormal renal function, while the recipient continues to have a functioning graft. HIV is well controlled in both individuals. This single case report highlights the possibility of acceptable long-term outcomes in living kidney donors with HIV as well as in donor-derived HIV transmission to kidney transplant recipients.

Early in the SARS-CoV-2 pandemic, convalescent plasma (CP) therapy was proposed as a treatment for severely ill patients. We conducted a CP treatment protocol under the Mayo Clinic Extended Access Program at University Hospital Brooklyn (UHB). Potential donors were screened with a lateral flow assay (LFA) for IgM and IgG antibodies against the SARS-CoV-2 S1 receptor-binding domain (RBD). Volunteers that were LFA positive were tested with an ELISA to measure IgG titers against the RBD. Subjects with titers of at least 1:1024 were selected to donate. Most donors with positive LFA had acceptable titers and were eligible to donate. Out of 171 volunteers, only 65 tested positive in the LFA (38.0%), and 55 (32.2%) had titers of at least 1:1024. Before our donation program started, 31 CP units were procured from the New York Blood Center (NYBC). Among the 31 CP units that were obtained from the NYBC, 25 units (80.6%) were positive in the LFA but only 12 units (38.7%) had titers of at least 1:1024. CP was administered to 28 hospitalized COVID-19 patients. Patients who received low titer CP, high titer CP and patients who did not receive CP were followed for 45 days after presentation. Severe adverse events were not associated with CP transfusion. Death was a less frequent outcome for patients that received high titer CP (>1:1024) 38.6% mortality, than patients that received low titer CP (≤1:1024) 77.8% mortality.

BACKGROUND: The coronavirus disease of 2019, also known as COVID-19, has been declared a global pandemic. Significant controversies exist regarding treatment modalities for this novel disease, especially in immunocompromised patients. Experience with management of COVID-19 in kidney transplant recipients is scarce; effects of this virus on immunosuppressed individuals are not well understood. METHODS: We identified 30 renal transplant recipients with confirmed COVID-19 pneumonia who were admitted to inpatient between March 2020 and April 2020. All patients received a 5-day course of hydroxychloroquine and azithromycin; half of the patients received methylprednisolone. During hospitalization, calcineurin inhibitors and antimetabolites were held; prednisone was continued. RESULTS: Clinical presentation of flu-like symptoms was similar to those in the general population. Hyponatremia, lymphopenia, acute kidney injury, and elevated inflammatory markers were common. Over the course of follow-up, 23 have been discharged home with a functioning allograft and in stable condition; 4 experienced acute kidney injury requiring renal replacement therapy; 7 patients were intubated, and 6 expired. The mortality rate in our cohort was 20%. CONCLUSION: Our findings described the characteristics and outcomes of this highly fatal illness in a multi-ethnic kidney transplant cohort, with insights on immunosuppression management that could further our understanding of this unique disease in immunocompromised populations.
