Metrics details. Rotavirus RV induces diarrhoea through a sequence of enterotoxic and cytotoxic effects. The former are NSP4-dependent, induce calcium-dependent chloride secretion and involve oxidative stress. Diosmectite DS is a natural clay that has been recommended as an active therapy for diarrhoea, but the mechanism of its effect is not clear. Electrical parameters may be used to measure the direct enterotoxic and cytotoxic effects in polar epithelial intestinal cells.

To investigate the effects of DS on RV-induced enterotoxic and cytotoxic damage. Caco-2 cells were used as a model of RV infection to evaluate chloride secretion, epithelial integrity, oxidative stress and viral infectivity in Ussing chambers.

Diosmectite reduced the expression of NSP4 and oxidative stress, resulting in a strong inhibition of chloride secretion. Preincubating RV with DS reduced the cytotoxic effect. Finally, the viral load was reduced by DS but not by control clay. This result suggests that DS specifically affects the early events of RV infection protecting the enterocyte, whereas it does not restore already-established cell damage. These findings indicate that DS exerts an anti-diarrhoeal effect by inhibiting viral replication and the expression of NSP4.

Both ion secretion and cell damage induced by RV are strongly inhibited consequent to the antiviral effect, which explains its clinical efficacy.

Diosmectite DS is a natural clay that acts on the intestinal epithelium without being absorbed and exerts multiple effects in the intestine [ 1 ]. It interacts with the mucous layer and inhibits the mucolysis of intestinal epithelial cells in rabbit ileum infected with enteropathogenic Escherichia coli [ 2 ].

DS increases the resistance of the intestinal epithelium to toxic stimuli in humans [ 3 ].

Anti-Diarrheal Effects of Diosmectite in the Treatment of Acute Diarrhea in Children

It upregulates the colonic expression of MUC2, which is the main secretory mucin, thereby protecting the epithelium from the antigens produced during the inflammatory process [ 4 ]. In addition, DS restores the intestinal barrier function in an in vitro model of inflammation [ 5 ].

Previous studies have indicated that DS absorbs bacterial toxins, bacteria and viruses [ 678 ]. Diosmectite is proposed as an active treatment for acute gastroenteritis AGE. The key treatment of AGE in children is the administration of oral rehydration solution ORS [ 9 ], but this neither shortens the duration of diarrhoea nor reduces the frequency of stool output.

Therefore, active therapies are now recommended as an adjunct to ORS. The latter have shown that DS reduces the stool volume in children with gastroenteritis, including those infected with RV [ 311 ].

Diosmectite

Rotavirus RV is the commonest aetiological agent of AGE in children and induces severe watery diarrhoea. Its severity is related to its mechanism of action, namely, a sequence of time-related mechanisms leading to secretory diarrhoea and intestinal epithelial damage [ 12 ]. In the early phase of infection, RV directly induces chloride and water secretion in the intestinal lumen through the enterotoxic effects of the non-structural viral protein NSP4. As recently reported, oxidative stress is a key mechanism in the enterotoxic effect induced by RV [ 14 ].

Following early ion secretion, RV infection results in severe damage to the structure of villi, with the disruption of epithelial integrity [ 15 ]. Clark et al. However, there are no data regarding the effects on RV infection.Diosmectite brand names SmectaSmecdral is a natural silicate of Aluminium and magnesium used as an intestinal adsorbent in the treatment of several gastrointestinal diseasesincluding infectious and non-infectious acute and functional chronic Diarrheaincluding irritable bowel syndrome diarrhea subtype.

Other uses include: chronic diarrhea caused by radiation-induced, chemotherapy-induced, and acquired immune deficiency syndrome-associated chronic diarrhea.

The use of Diosmectite as an adjuvant to rehydration therapy for acute infectious functional diarrhea in children may reduce the duration of diarrhea by starting its use from day one; it increases cure rate by third day; and may reduce stool output but has no effect on hospitalization rates or need for intravenous therapy. Its effectiveness in improving stool consistency is the result of its ability to absorb bacteria, viruses and toxins as well as strengthening the intestinal mucus barrier to reduce luminal antigens passing through the mucus barrier which in turn helps to reduce inflammation.

Sign Up.Background: Diosmectite DSan antidiarrheal absorbent natural clay, was proposed for treatment of acute gastroenteritis and more recently considered for diarrhea within the functional bowel disorder syndrome.

Objective: To review pharmacology efficacy, mechanisms of action and safety of DS. Conclusions: Solid data show that DS is effective in infectious diarrhea, mainly as an ion antisecretory agent and in preventing intestinal damage.

Despite clinical data being consistent and convincing, DS is not considered as first-line treatment because of the presence of alternative therapeutic options.

This differs from a mechanism of action, as it is a more specific term that focuses on the interaction between the drug itself and an enzyme or receptor and its particular form of interaction, whether through inhibition, activation, agonism, or antagonism. Not applicable. Its mechanisms of action are not yet fully understood, but are probably multiple. Disinfectants having same mechanism may lead to develop the resistance in microbes.

Although the exact mechanism of action of macrolides is not clear, it has been hypothesized that macrolides show their action by blocking protein synthesis in bacteria in the following ways: 1 Preventing the Transfer of the Peptidyl tRNA from the A-site to the P-site. All hormones can be divided two groups, water-soluble and lipid-soluble. There are various classes of neurotransmitters, with different functions and mechanisms of action. As a result, some hormones exist in two forms, free and bound.

To better understand the mechanism of hormone action, it is crucial to comprehend various definitions. Oral zinc for treating diarrhoea in children. The animation begins by introducing the Philadelphia Chromosome, the result of a reciprocal translocation between chromosomes 9 and Though it is not approved for use around the world, and is unavailable in the United Kingdom and the United States, it is considered to be safe for use and is frequently administered to young children and infants as well as to adults.

It is important to utilize different types of sanitizers in pharmaceuticals because the mode of action in each is needed to prevent the resistance of microbes. It has also been known to relieve inflammation in the digestive system and can also help to rid the body of certain viruses or bacteria. These outbreaks have resulted in reconsideration of the safety of oysters harvested from contaminated waters in other countries.Acute diarrhea caused by an infectious organism is highly prevalent, particularly in developing countries, and is usually self-limiting.

The condition is a major contributor to the global disease burden and is associated with a significant economic cost. Diarrhea almost always occurs by one or more of four mechanisms: disruption of osmotic forces in the intestine; disruption of normal secretory processes; disruption of epithelial cells or the epithelial tight junctions; or motility disorders.

Oral rehydration therapy ORT is central to the management of acute diarrhea, and is sufficient to prevent complications due to dehydration in most patients while the disease runs its course. However, ORT has no effect on the duration of the disease or frequency of bowel motions, and any agent that could meet these needs would therefore be a useful addition to ORT.

Diosmectite is a natural aluminomagnesium silicate clay with a lamellar, non-fibrous crystalline structure that gives it strong adsorbent properties.

Its mechanisms of action are not yet fully understood, but are probably multiple. Diosmectite reduces inflammation, modifies mucus rheologic properties, inhibits mucolysis, and adsorbs bacteria, bacterial enterotoxins, viruses and other potentially diarrheogenic substances.

A number of studies have shown that diosmectite reduces the duration of diarrhea and decreases the frequency of bowel motions after 2 days of treatment in children with mild-to-moderate acute diarrhea.

Two recent trials have indicated a reduction in stool output with diosmectite. Because of its very favorable safety profile, with no serious adverse effects, diosmectite is frequently used, mainly in European countries but also in Asia and Africa. Diosmectite should be used as an adjunct, not an alternative, to ORT and, when needed, to antibacterial therapy.

Diosmectite should be used as an adjunct, not an alternative, to ORT and, when needed, to antibacterial therapy. Acute diarrhea is defined as a diarrheal disease consisting of the passage of unformed or watery stools three or more times per day lasting up to 14 days.

Diarrhea occurs as the result of a nonspecific intestinal response to various stimuli, including infections, drugs, and inflammatory bowel disease. Acute diarrhea is attributable to various infectious causes, although the infecting organism s often cannot be identified.

Invasive diarrhea occurs when the infecting pathogen crosses the mucosal lining of the gastrointestinal GI tract. Viruses, particularly rotavirus, are the predominant pathogens associated with diarrhea in developed countries, while bacteria are the most frequent cause in developing regions.

Diarrhea occurs when absorptive and secretory changes increase the volume of water that enters the colon to a level beyond its absorptive capacity.

It almost always arises as a result of one or more of four basic mechanisms: osmotic diarrhea, secretory diarrhea, exudative diarrhea, and diarrhea associated with motility disorders.

Osmotic diarrhea occurs when large quantities of poorly absorbed, low molecular-weight solutes in the lumen drive the transport of excessive water into the lumen via osmotic forces.

In exudative diarrhea, bacterial and viral pathogens destroy epithelial cells or disrupt the tight junctions of the intestinal epithelium.
