Abstract

Insights

Hepatobiliary ascariasis was found in 14.8% of recurrent pyogenic cholangitis (RPC) patients in India, suggesting a potential link. Recurrent pyogenic cholangitis cases were also associated with multi-drug-resistant bacteria, indicating carbapenems as a possible treatment.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Microbiology

Background:

  • Recurrent pyogenic cholangitis (RPC) is prevalent in Eastern India, with its exact cause debated.
  • Hepatobiliary Ascaris infestation is a suspected factor in RPC pathogenesis in Eastern Asia, but Indian data is limited.
  • RPC is frequently linked to multi-drug-resistant (MDR) bacteria, contributing significantly to patient morbidity and mortality.

Purpose of the Study:

  • To investigate the potential role of hepatobiliary ascariasis in the development of RPC.
  • To characterize the microbial profile of RPC patients.
  • To evaluate the implications of microbial findings for managing RPC.

Main Methods:

  • A comparative study of consecutive patients with biliary stones undergoing surgery from March 2020 to December 2021 in Eastern India.
  • Patients were categorized into RPC and non-RPC groups.
  • Bile and biliary stone samples were analyzed for bacterial culture, microscopy, and histopathology to detect ascariasis and identify microbial pathogens.

Main Results:

  • Hepatobiliary ascariasis was identified in 14.8% of RPC patients (8 out of 54), with no cases found in the non-RPC group.
  • Klebsiella was the predominant bacterial pathogen isolated from bile.
  • A high incidence of MDR pathogens (79%) was observed in RPC patients, with carbapenem antibiotics showing the highest sensitivity (66.6%).

Conclusions:

  • The study indicates a higher prevalence of hepatobiliary ascariasis in RPC patients, although a definitive etiological link requires further investigation.
  • RPC is strongly associated with a high prevalence of MDR bacteria.
  • Carbapenems may be considered a suitable empirical antibiotic choice for managing RPC.

Bacterial Phylum Chlamydiae

The phylum Chlamydiae or Chlamydiota is composed of a single order, Chlamydiales. This phylum consists entirely of obligate intracellular parasites that infect eukaryotic hosts. While human pathogens within this group have been studied extensively, the phylum encompasses many species capable of interacting with various eukaryotic organisms. Members of Chlamydiae are typically small cocci, approximately 0.5 μm in diameter, and exhibit a distinctive developmental cycle. As is characteristic...

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
