Which electrolyte abnormality is listed as a negative prognostic indicator in parvovirus infection?

Which electrolyte abnormality is listed as a negative prognostic indicator in parvovirus infection?

• A. Higher CRP
• B. Vomiting, depression, hypoalbuminemia, lymphopenia
• C. Hypocholesterolemia
• D. Hyperglycemia

Answer: (C)

Hypocholesterolemia signals more severe systemic disease in parvovirus infection. When the infection becomes extensive, there is profound inflammation and hepatic dysfunction, along with intestinal protein-losing enteropathy. The liver’s ability to synthesize lipids and transport lipoproteins drops, and overall nutritional status worsens, so serum cholesterol levels fall. This drop reflects the body’s overwhelmed state and has been linked with higher mortality in affected patients, making it a negative prognostic indicator. The other options either describe non-electrolyte findings (like inflammation marker CRP or clinical signs) or represent less-specific metabolic changes; they don’t specifically capture the prognostic signal that low cholesterol provides in severe parvoviral disease.
