El cólera, el cólera no vibratorio y el ácido estomacal
Lancet (London, England)
|October 21, 1978
Resumen
El bajo nivel de ácido estomacal (hipoclorhidria) no es el resultado del cólera, pero puede predisponer a las personas a enfermedades graves. Esta condición podría explicar las altas tasas de diarrea por patógenos sensibles al ácido en los países en desarrollo.
Área de la Ciencia:
- Gastroenterología y Gastroenterología.
- Enfermedades infecciosas Enfermedades infecciosas.
- Epidemiología La epidemiología.
Sus antecedentes:
- El cólera es una preocupación importante para la salud pública, especialmente en los países en desarrollo.
- Se ha observado una reducción de la producción de ácido estomacal (hipoclorhidría) en pacientes con cólera, pero su relación causal no estaba clara.
Objetivo del estudio:
- Investigar si el cólera causa hipoclorhidria o si la hipoclorhidria es un factor predisponente para el cólera severo.
- Explorar el papel de la hipoclorhidria en la incidencia de enfermedades diarreicas causadas por patógenos sensibles al ácido.
Principales métodos:
- Se midió el ayuno y la producción de ácido estomacal postprandial en pacientes bengalíes que se recuperaban de cólera.
- Se evaluó la producción de ácido basal y estimulada por betazol-clorhidrato en voluntarios estadounidenses antes y después de la infección por cólera.
Principales resultados:
- 16 de los 37 pacientes de Bangalee mostraron una baja producción de ácido estomacal después del cólera.
- El ácido gástrico de los pacientes hipoclorhidricos no pudo matar a los vibrios de cólera in vitro.
- El cólera no alteró la secreción de ácido estomacal en voluntarios estadounidenses.
- La baja producción de ácido antes del cólera se correlacionó con un aumento de la gravedad del cólera.
Conclusiones:
- La hipoclorhidria en pacientes de cólera de Bengalee precede a la infección y no es causada por ella.
- La hipoclorhidria tropical idiopática puede ser un factor de riesgo significativo para las enfermedades diarreicas en los países en desarrollo.
- Comprender los patógenos sensibles al ácido y los factores de acogida es crucial para las intervenciones de salud pública.

Stomach pH Regulation
The human body carefully regulates the internal pH of different organs to maintain homeostasis. For example, while the blood plasma maintains a neutral pH of 7, the stomach lumen has an acidic pH of 1.5 - 3.5. The low pH of stomach lumen helps kill pathogens in the food and break down complex food molecules.
The acid-secreting gastric mucosal epithelial cells (parietal cells) lining the stomach lumen maintain the low pH in the lumen. Numerous ion transporters and channels on these parietal...

Acids, Bases and Neutralization Reactions
Acids and bases play several important roles in biology. The pH of a biological system can significantly impact the function of biological molecules, including enzymes, proteins, and nucleic acids. For example, enzymes have optimal pH ranges for their activity, and changes in pH can denature or alter their structure, affecting their function. Acids and bases also play a crucial role in cellular signaling and communication. The pH of the extracellular fluid around cells can influence the...
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,...
Reservoir of Infection
Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
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...
Cholera
Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...
