Insights

A patient with hepatitis C developed Vibrio vulnificus septic shock after eating undercooked fish. Combined therapy including Polymyxin B hemoperfusion and IVIg reversed shock and lowered IL-6 levels.

Area of Science:

  • Infectious Diseases
  • Critical Care Medicine
  • Dermatology

Background:

  • Hepatitis C infection can predispose individuals to severe bacterial infections.
  • Undercooked seafood is a known source of Vibrio vulnificus.
  • Septic shock presents a critical medical emergency requiring prompt intervention.

Observation:

  • A 54-year-old man with hepatitis C presented with shock and enterocolitis-like symptoms after consuming undercooked mackerel.
  • Skin eruptions evolved into annular erythema with vesicles.
  • Initial treatment with corticosteroids and cefotiam did not prevent shock exacerbation.

Findings:

  • Vibrio vulnificus septic shock was diagnosed via skin biopsy culture.
  • Combined therapy with piperacillin, intravenous immunoglobulin (IVIg), and Polymyxin B immobilized fiber (PMX-F) hemoperfusion led to shock reversal.
  • Significant reduction in serum Interleukin-6 (IL-6) levels was observed, correlating with treatment efficacy.

Implications:

  • Hemoperfusion with PMX-F and IVIg is a potentially effective treatment strategy for severe Vibrio vulnificus septic shock.
  • This case suggests that debridement may not always be necessary in Vibrio vulnificus sepsis.
  • Monitoring IL-6 levels can be useful in assessing treatment response in septic shock.

Bacterial Toxins01:12

Bacterial Toxins

Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...
Cholera01:25

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Diphtheria01:28

Diphtheria

Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
Botulism01:22

Botulism

Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...
