Дирофиляриоз – инфекция, которая широко распространена среди собак в Северной и Южной Америке, Австралии, Южной Азии, Японии, регистрируется в европейском регионе. Дирофиляриоз у людей длительное время считали редким, характерным преимущественно для стран с жарким климатом заболеванием. У человека паразит обычно не достигает взрослой стадии и остается в незрелой форме. Это может вызвать синдром мигрирующей личинки и образование подкожных узелков. В данной публикации представлен клинический случай дирофиляриоза, выявленного в Республике Беларусь и претендующего на роль «местного» возбудителя. Согласно результатам гистологического исследования извлеченного паразита особь не обладала свойствами половозрелого организма, имела морфологические признаки, характерные для личинки. Учитывая наличие у пациентки постоянного контакта с собаками, проживающими на дворовой территории, проявление локальных признаков потенциального места внедрения возбудителя, появление множественных подкожных узелков (со слов пациента), вероятнее всего, речь идет о повторном инфицировании. С учетом анамнеза отсутствия посещения регионов, эндемичных по дирофиляриозу, расширяющегося ареала распространения возбудителя, представленный случай может быть отнесен к аутохтонному. Dirofilariasis is a widespread infection among dogs in North and South America, Australia, South Asia, Japan, and it is registered in the European region. Dirofilariasis in humans has long been considered rare, characteristic mainly of countries with hot climates. In humans, the parasite usually does not reach the adult stage and remains in an immature form. This can cause migrating larva syndrome and the formation of subcutaneous nodules. This publication presents a clinical case of dirofilariasis identified in the Republic of Belarus and claiming to be a “local” pathogen. According to the results of histological examination of the extracted parasite, the individual did not possess the properties of a sexually mature organism, had morphological signs characteristic of a larva. The patient in this case had constant contact with dogs living in outside, the manifestation of local signs of a potential site of introduction of the pathogen, the appearance of multiple subcutaneous nodules, most likely we are talking about re-infection. Taking into account the anamnesis of the absence of visits to regions endemic to dirofilariasis, the expanding range of the pathogen, the presented case can be attributed to local case.

The article presents the current state of the problem of dirofilariasis. Helminth infection caused by nematodes of the genus Dirofilaria is mainly a disease of carnivores from the canine and feline families. Humans are considered occasional hosts in which Dirofilaria spp., more commonly D. repens, rarely reach sexual maturity. The climatic conditions of the territory are one of the determining factors for the spread of vector-borne diseases. Due to the fact that in recent years there has been a tendency to increase average temperatures everywhere, these changes lead to a shift and expansion of the ranges of many organisms, including pathogens and vectors of various diseases. The clinical picture of human dirofilariasis caused by D. repens most often manifests itself in one of two clinical forms -subcutaneous and ocular, although, according to the literature, there are cases of damage to other localizations. Due to the fact that damage to the organs of vision occurs most often in humans, the clinical case presented by us is relevant. The patient, in our clinical case, permanently lived in one of the districts of the Ryazan region. The landscape and natural complex of this region, taking into account the presence of a large number of wetlands, an abundance of water bodies and suitable climatic conditions, creates a favorable environment for the development of insects of the Culicidae family (mosquitoes of the genera Anopheles, Culex, etc.), which are transmissible carriers of various human and animal diseases, including dirofilariasis. The complex cycle of the parasite, the possibility of migration in the body can lead to multiple organ damage. Scientific publications describe cases of finding dirofilaria in the lungs, heart, and genitourinary system. In this regard, the awareness of doctors and patients about this disease is very relevant, and will reduce the likelihood of prolonging the correct diagnosis and treatment.
