L-Ornithine-L-Aspartate and Intermittent Renal Replacement Therapy in Fulminant Hepatitis A: A Case Report

Hepatitis A is a common viral infection worldwide that is transmitted via the fecal-oral route. Since the introduction of an efficient vaccine, the incidence of infection has decreased but the number of cases has risen due to widespread community outbreaks among unimmunized individuals. Classic symptoms include fever, malaise, dark urine, and jaundice, and are more common in older children and adults. People are often most infectious 14 days prior to and 7 days following the onset of jaundice. We will discuss the case of a young male patient, diagnosed with acute hepatitis A, leading to fulminant hepatitis refractory to conventional therapy and the development of subsequent kidney injury. The medical treatment through the course of hospitalization was challenging and included the use of L-ornithine-L-aspartate and prolonged intermittent hemodialysis, leading to a remarkable outcome. Hepatitis A is usually self-limited and vaccine-preventable;supportive care is often sufficient for treatment, and chronic infection or chronic liver disease rarely develops. However, fulminant hepatitis, although rare, can be very challenging to manage as in the case of our patient.Copyright © 2023 The Author(s).

Corynebacterium amycolatum infective endocarditis in a patient with severe COVID-19: a case report.

Objective. To present a case of successful treatment of a secondary bacterial infection caused by non-diphtheritic corynebacterium in a patient with severe COVID-19 and known beta-lactam intolerance. Materials and methods. A clinical case of infective endocarditis (IE) caused by Corynebacterium amycolatum in a 74-year-old patient hospitalized with severe COVID-19 is presented. Comorbidity (secondary immune deficiency due to active malignancy, chemotherapy courses;previous heart disease) and the need for immunosuppressive therapy were triggers for infection caused by a rare Gram-positive bacterium which is usually considered as clinically non-significant. The choice of empiric antimicrobial treatment was limited by the patient's history of beta-lactam intolerance. Results. A multidisciplinary approach to medical care of the patient and alertness to secondary infections helped to diagnose IE in a timely manner and to choose effective antimicrobial therapy. Combination therapy with vancomycin and amikacin helped to make blood flow free from infection. The further switch to oral doxycycline in outpatient settings resulted in the patient recovery from the infection. Conclusions. Under conditions of limited choice of drug therapy, it is critical to have access to modern microbiological diagnostics which make it possible to diagnose rare pathogens. A dialogue between treating physician and clinical pharmacologist helps to choose an empirical and targeted antimicrobial therapy with the best efficacy-safety ratio. There is a need to be alert to secondary infections, including those of atypical locations and courses and caused by rare or opportunistic pathogens.Copyright © 2022, Interregional Association for Clinical Microbiology and Antimicrobial Chemotherapy.

An unusually fulminant case of encephalomyelitis in an 80 year old

Background: There have been reports of demyelinating syndromes in association with COVID-19 and to a much lesser extent COVID 19 vaccines. The association between demyelination and vaccines, in general, remains controversial. We review a presentation of fulminant demyelination, and discuss antecedent COVID-19 vaccination, the formulation of a broader differential diagnosis and ultimately the pathologic diagnosis. Case presentation: An 80-year-old woman presented with seizure, encephalopathy, quadriparesis and ultimately expired. She received a SARS-CoV-2 vaccine one day prior. Imaging revealed contrast enhancing cerebral lesions, longitudinally extensive transverse myelitis. CSF was markedly inflammatory. Pathologic examination of the CNS lesions revealed demyelination and inflammation beyond white matter, not restricted to a perivenular distribution. Conclusion(s): This case depicts a seemingly fulminant course of a diffuse demyelinating syndrome characterized clinicopathologically as Marburg's variant of multiple sclerosis. There are several unique aspects of this case including the extremely rapid course, the unusual evolution of CSF abnormalities, with hypoglycorrhachia and markedly elevated protein. The proximity to vaccination is a pertinent association to document, though we cannot unequivocally prove causation.Copyright © 2022 The Authors

Massive empyema due to Lactococcus garvieae

Introduction Lactococcus garvieae, a zoonotic pathogen, may rarely infect humans through the consumption of fish. Documented manifestations of L. garvieae infection in humans include infective endocarditis, prosthetic joint infections, liver abscesses, peritoneal dialysis-associated peritonitis, osteomyelitis, meningitis, infective spondylodiscitis, acalculous cholecystitis, and urinary tract infection. Case report An 87-year-old female was hospitalized for coffee-ground emesis secondary to acute gastritis after eating cooked fish. One week after her discharge, she developed new-onset confusion and was returned to the hospital. Chest computed tomography revealed total consolidation of the left lung and a multiloculated left pleural effusion. The patient required intubation and direct admission to the intensive care unit. Pleural fluid and blood cultures grew L. garvieae, which was susceptible to ceftriaxone, penicillin, and vancomycin. Despite intensive antibiotic therapy and supportive care for thirteen days, the patient remained in irreversibl e shock, and the family opted for comfort care. Conclusions Heretofore unreported, this case demonstrates that L. garvieae can cause bronchopneumonia and empyema. Copyright © GERMS 2022.
