    Insights

    Normal human immunoglobulin effectively protected newborn infants from echovirus 11 infections during an epidemic. This treatment prevented illness in 205 exposed infants, highlighting its value for neonatal care.

    Area of Science:

    • Virology
    • Neonatal Medicine
    • Immunology

    Background:

    • An echovirus 11 epidemic in 1982 affected a special-care baby unit, causing severe illness and death in infants.
    • Infections presented with meningitis, respiratory distress, and other serious complications.

    Purpose of the Study:

    • To evaluate the efficacy of normal human immunoglobulin in preventing echovirus 11 infection in newborn infants.
    • To assess the safety and protective action of immunoglobulin against echovirus 11.

    Main Methods:

    • Intramuscular administration of normal human immunoglobulin (250 mg) containing echovirus 11 antibodies to exposed newborn infants.
    • Clinical monitoring for symptoms and ill-effects post-administration.
    • Serological studies to confirm antibody presence and protective action.

    Main Results:

    • None of the 205 infants receiving immunoglobulin immediately after delivery developed symptoms or adverse effects.
    • Confirmed infections in 21 infants prior to immunoglobulin administration included fatalities and severe morbidity.
    • Serological data supported the protective role of antibodies in immunoglobulin.

    Conclusions:

    • Normal human immunoglobulin is a valuable prophylactic measure for newborn infants exposed to echovirus 11.
    • Early administration of immunoglobulin provides a crucial safeguard against severe outcomes of echovirus 11 infection in neonates.
    • The study reinforces the importance of antibody-based interventions in managing neonatal viral epidemics.

    Bacterial Meningitis01:24

    Bacterial Meningitis

    Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

    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...

    Viral Meningitis

    Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

    Respiratory Syncytial Virus Disease

    Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
