Rivero-Corvalho Symptom

Rivero-Corvalho syndrome is a clinical and laboratory syndrome manifested in the form of eosinophilia, leukocytosis, increased ESR and the level of C-reactive protein in the blood in patients with allergic diseases. It is also characterized by an increase in the concentration of IgE in the blood serum in combination with an increase in the level of total IgE and IgA in the secretion.

The syndrome was first described in 1988 by Spanish physician Joaquín Rivero-Corvaló. In 1990, he proposed the name “Rivero-Corvalo syndrome” for this syndrome.

In 2006, at an international conference in Rome, it was proposed to rename the syndrome “Rivero-Corvalier syndrome”, since the word “syndrome” is too general for this condition.

Rivero-Corvallo syndrome is characterized by eosinophilia, leukocytosis, increased ESR and CRP levels in the blood serum, as well as increased levels of IgE, IgA and total IgE in secretions. It can be caused by various allergic reactions such as atopic dermatitis, bronchial asthma, urticaria, etc. This condition may be associated with chronic inflammation of the airways caused by an allergic process.

Treatment of Rivero-Corval symptoms involves the use of antihistamines, corticosteroids and other medications aimed at eliminating the allergic reaction. Immunotherapy techniques such as desensitization and immunotherapy may also be used.

Rivero-Corvalho is an involuntary grasping reaction of the upper limbs during swallowing, most often occurring during prolonged sitting with the head tilted forward. At rest, the process of swallowing is carried out using the muscles of the tongue, which connect the pharynx to the esophagus. A grasping reaction can occur without disruption of the act of swallowing (
