Insights

Probiotics, like Lactobacillus and Saccharomyces cerevisiae, are beneficial bacteria and fungi used for gut health and diarrhea prevention. While generally safe, this review examines their potential risks, particularly for immunocompromised individuals.

Area of Science:

  • Microbiology
  • Gastroenterology
  • Immunology

Background:

  • Probiotics are live microorganisms conferring health benefits.
  • Commonly used probiotics include Lactobacillus species and Saccharomyces cerevisiae.
  • They are widely employed as dietary supplements for gastrointestinal health.

Purpose of the Study:

  • To review the established indications for probiotic use.
  • To critically evaluate the potential risks associated with probiotics.
  • To specifically assess risks in immunocompromised patient populations.

Main Methods:

  • Literature review of scientific articles on probiotics.
  • Analysis of studies detailing probiotic efficacy and safety.
  • Focus on clinical data concerning adverse events.

Main Results:

  • Probiotics modulate pathogenic growth and invasion in the bowel.
  • Lactobacillus and Saccharomyces cerevisiae are frequently utilized.
  • While generally safe, invasive infections are reported in specific patient groups.

Conclusions:

  • Probiotics offer therapeutic potential for various conditions, notably diarrhea.
  • Immunocompromised patients may face heightened risks.
  • Careful consideration of risk-benefit is essential, especially in vulnerable populations.

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
Microbiota Modulation by Antibiotics01:21

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Microbiota of the Stomach and Small Intestine01:27

Microbiota of the Stomach and Small Intestine

The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
