A family case of giardiasis manifested as allergic urticaria in the joint practice of a family doctor and a pediatrician

Abstract

To date, giardiasis remains an urgent disease in the practice of family doctors, internists and pediatricians. Family cases of giardiasis are quite common. If one case of giardiasis is detected in the family, it is necessary to examine all family members. Currently, giardiasis remains relevant, especially in pediatrics. The difficulty of detecting giardiasis in children is primarily due to the fact that its manifestations are often disguised as various clinical variants of gastroenterological pathology (functional disorders of the gastrointestinal tract, syndrome of excessive growth of microflora in the small intestine, malabsorption syndrome) and often occur with the clinic of allergic diseases — recurrent urticaria, atopic dermatitis, gastrointestinal forms of food allergies and others forms.

The article presents a clinical case of familial giardiasis, in which the primary diagnosis of the disease in a child caused the greatest difficulty due to its allergic manifestations by the type of severe urticaria in the presence of possible allergens at home, which led to a long diagnosis and two emergency hospitalizations in children’s hospitals, where despite the examination and treatment, the correct diagnosis was not suspected timely. Differential diagnosis at the first stages of patient management was carried out between allergic urticaria, infectious mononucleosis and streptococcal infection, the possibility of giardiasis was not considered. Difficulties in diagnosis led to the appointment of systemic glucocorticosteroids and unjustified antibacterial therapy. Indirectly, prolonged diagnosis and untimely start of treatment led to a decrease in motivation for examination and treatment of the patient’s parents due to distrust of doctors.
