    Insights

    Severe bacterial infections can cause jaundice, a condition with a high mortality rate. This study suggests a selective defect in conjugated bilirubin excretion, not true cholestasis, in these patients.

    Area of Science:

    • Hepatology
    • Infectious Diseases
    • Critical Care Medicine

    Background:

    • Jaundice can occur during severe bacterial infections.
    • The underlying mechanisms of jaundice in infection are not fully understood.
    • Previous studies have not clearly defined the pattern of liver enzyme abnormalities.

    Purpose of the Study:

    • To investigate the clinical and biochemical features of jaundice associated with severe bacterial infections.
    • To differentiate this type of jaundice from other causes of liver dysfunction.
    • To explore the potential mechanisms of bilirubin elevation in infected patients.

    Main Methods:

    • Retrospective analysis of 30 patients with jaundice and severe bacterial infection.
    • Review of clinical data, blood cultures, and biochemical tests including bilirubin, alkaline phosphatase, transaminases, cholesterol, urea, creatine phosphokinase, and lactic dehydrogenase.
    • Liver histology examination in a subset of patients.

    Main Results:

    • High mortality rate (43%) observed in the patient group.
    • Elevated conjugated bilirubin with normal or mildly elevated alkaline phosphatase and transaminases.
    • Significant elevation in serum urea, creatine phosphokinase, and lactic dehydrogenase; normal serum cholesterol.
    • Histological findings showed mild to moderate bile stasis in some patients, but otherwise nonspecific changes.
    • No correlation between jaundice severity/duration and prognosis.

    Conclusions:

    • Jaundice in severe bacterial infections may represent a selective defect in conjugated bilirubin excretion rather than true cholestasis.
    • The observed biochemical profile suggests a specific impairment in bilirubin transport or metabolism.
    • Further research is needed to elucidate the precise pathophysiological mechanisms involved.

    Changes in Skin Color: Clinical Perspectives

    The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
    Albinism
    Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

    Diseases of the Liver and Gallbladder

    Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
    Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

    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...

    Bacterial Meningitis I: Introduction

    Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

    Jaundice01:25

    Jaundice

    Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

    Cholecystitis01:20

    Cholecystitis

    Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
