The clinical presentation of toxocariasisa zoonotic parasitosis transmitted from dogs and cats to humans, can be very diverse, which is one of the reasons why Toxocara-related disease may go unnoticed. In brief, the diagnosis of human toxocariasis relies mainly on patient data, anamnestic information, symptoms, eosinophil count and total-IgE levels. Toxocariasis is one of the most commonly reported zoonotic helminth infections in the world with a higher prevalence in tropical settings and in rural populations.
It is caused by the larval stages of the ascarids Toxocara canis, the common roundworm exovtalmos dogs, and probably also by the larval stages of Toxocara cati, the roundworm of cats. The clinical spectrum of toxocariasis in humans varies from asymptomatic infection to severe organ injury caused by larval migration to the major organs “visceral larva migrans”.
Clinical involvement of the nervous system in visceral larva migrans due to Toxocara is thought to be rare, although causaas experimental animals the larvae frequently migrate to the brain.
The CNS migration leads to a variety of neurological disorders such as meningo-encephalitis, space-occupying lesion, cerebral vasculitis, epilepsy, and myelitis. Several studies have evidenced high seropositivity rates for T. Diagnosis of neurotoxocariasis is based on the history; blood tests, including differential blood cell count; CSF investigations, including determination of antibodies anti-Toxocara canis; and neuroimaging.
Like the visceral manifestations, neurological manifestations of toxocariasis are treated with benzimidazole components. Ocular toxocariasis is an uncommon worldwide parasitic infection that affects mostly children and is found in both rural and metropolitan areas.
In many parts of the world, parasitic infections of the eye are a major cause of blindness. The diagnosis of toxocariasis is essentially clinical, based on the lesion morphology and supportive laboratory data such as serum enzyme-linked immunosorbent assay ELISA titers and ELISA Toxocara titers on aqueous humor; other diagnostic methods are imaging studies including optical coherence tomography, fluorescein angiography, computed tomography, and ocular ultrasound.

Treatment is directed at complications arising from intraocular inflammation and vitreous membrane traction. Early vitrectomy may be of value both diagnostically and therapeutically. Signs and Symptoms Many kids won’ Highlights of human toxocariasis. Human toxocariasis is a helminthozoonosis due to the migration of Toxocara species larvae through human organism.
Humans become infected by ingesting either embryonated eggs from soil geophagia, picadirty hands or raw vegetables, or larvae from undercooked giblets. The diagnosis relies upon sensitive immunological methods ELISA or western-blot which use Toxocara excretory-secretory antigens. Seroprevalence is high in developed countries, especially in rural areas, and also in some tropical islands.
The clinical spectrum of the disease comprises four syndromes, namely visceral larva migrans, ocular larva migrans, and the more recently recognized “common” in adults and “covert” in children pictures. Therapy of ocular toxocariasis is primarily based upon corticosteroids use, when visceral larva migrans and few cases of common or covert toxocariasis can be treated by anthelmintics whose the most efficient appeared to be diethylcarbamazine.

When diagnosed, all of these syndromes require thorough prevention of recontamination especially by deworming pets and sanitary education. Ocular toxocariasis in Korea. To analyze the characteristics and clinical manifestations of clinically diagnosed and exodtalmos confirmed ocular toxocariasis in patients. Thirty-three eyes of 33 patients diagnosed as having ocular toxocariasis at the Hallym University Medical Center between January and December were included in causaas study.
The diagnosis of ocular toxocariasis was based on clinical features and confirmed serologically by enzyme-linked immunosorbent assay and immunoblotting. All patients were interviewed by using a structured questionnaire that included risk factors that might account for the introduction of Toxocara larvae. Demographics, social characteristics determined from the questionnaire, and clinical features were evaluated.
Meaning of “enoftalmo” in the Portuguese dictionary
A total of 33 eyes of 33 patients were enrolled in this study: The toxocariasis was unilateral in all patients, and the exoftalmow was acute in two-thirds of the patients. Ocular toxocariasis in Korea usually affects young adults to middle-aged men. The clinical manifestation is unilateral and presents as acute inflammation with a peripheral inflammatory mass. Visual prognosis with appropriate treatment is good.
Toxocariasis is a parasitosis which complicates the accidental infestation of the humans by larvae of a roundworms belonging of the genus Toxocara.
In adults, the discovery is often incidental during a hypereosinophilia check-up. Clinical signs are not specific and depend on affected organs.
We report the case of a year-old-woman who has consulted for a recent cough, after spontaneous resolution of abdominal pain. The laboratory examination isolated an hypereosinophilia and the liver sonography showed two hypoechogenic nodules. The CT-scan found bilateral lung nodules with ground glass halo.
Broncho-alveolar lavage identified caudas eosinophilic alveolitis.
Positive serologic results for toxocariasis and western blot results allowed to wxoftalmos to the diagnosis of pulmonary and hepatic toxocariasis. Although rare, pulmonary toxocariasis should be suspect in any lung eosinophilia, especially if the patient has never traveled. Toxocariasis is today the most widespread zoonotic, helminthic infection in Russia and other countries of the world. A large population of Toxocara has recently inhabited the urban populations of dogs and cats.
Human toxocariasis is polymorphic, from its subclinical course to significant organ pathology, and detectable as a manifestation of eosinophilia, fever, hepatomegaly, hyperglobulinemia, lung and central nervous system lesions, myocarditis, and skin rash. The diagnosis of toxocariasis is established by its clinical presentation and serological findings. It is important in the history that children have spent much time with dogs or cats. Laboratory diagnosis of human toxocariasis.
Toxocariasis is a helminth zoonosis caused by infection exoftalos the larvae of Toxocara spp. Only two species, Toxocara canis and Toxocara cati, are recognised as causative agents of human disease.
The best choice for serodiagnosis of the generalised forms of toxocariasisvisceral larva migrans VLM or covert toxocariasisrelies upon the initial use of TES-ELISA, after which any positive result should subsequently be tested by Western blotting WB. Covert toxocariasis is mostly a benign infection, so a large majority of infected subjects are asymptomatic or have very few symptoms and therefore go undiagnosed.
In this form, this helminthosis is often self-limiting, leaving residual specific antibodies. A positive serodiagnosis caused by residual antibodies that do not have any diagnostic significance can be associated with any infectious or non-infectious disease. If separated from the ongoing clinical and laboratory context, such a positive result has no diagnostic value and should be only taken into account after the possible etiologies of any observed syndromes have been ruled out.
Unlike the methods used for the immunodiagnosis of bacterial, viral or protozoal toxoplasmosis infections, it is not possible with toxocariasis to assess the age of the presence of specific IgG using the levels of specific IgM because IgM antibodies can be found throughout the course of helminthiasis.
The detection of other classes of immunoglobulins, namely IgE and IgA, the subclasses, namely IgG4 or circulating Ag was proven to be unable to discriminate between active and self-cured generalised toxocaral infections. Currently, the diagnosis of an active covert toxocariasis relies upon indirect arguments, e.
This situation is far from ideal and more research should be carried out to solve this difficult problem. To evaluate ophthalmic ultrasound findings in the three presentation forms of ocular toxocariasis peripheral or posterior pole granulomas and chronic endophthalmitisin patients with confirmed diagnosis of ocular toxocariasis. The patients were submitted to an ocular ultrasound examination MHz transducer, contact technique. In the series of 11 patients, mean age was 7.
In the analyses of compromised eyes 11 eyesthe ophthalmoscopic examination revealed the following distribution of the 3 forms of ocular toxocariasis: The most consistent ultrasound finding in the eye with toxocariasis was a high-reflectivity retinal mass, located in posterior pole or periphery, which may be calcified, and which has as main characteristic the adherence of vitreous membranes.
In addition to clinical history, systemic evaluation and serology, the ultrasound can help in the diagnosis of ocular toxocariasisespecially in media opacities.
Toxocariasis is a parasitic infection produced by helminths that cannot reach their adult stage in humans. For their etiological species Toxocara canis and Toxocara catiman is a paratenic host. Infection by such helminths can produce a variety of clinical manifestations, such as: In the visceral larvae migrans syndrome, the organs that are mainly involved include liver, lungs, skin, nervous system, muscles, kidneys and the heart.
Regarding the latter, the importance of cardiovascular manifestations in toxocariasisas well as its clinical relevance, has increasingly begun to be recognized. The current article is based on a systematic information search, focused mainly on the clinical and pathological aspects of cardiovascular manifestations in toxocariasisincluding its pathophysiology, laboratory findings, diagnosis and therapeutical options, with the objective of highlighting its importance as a zoonosis and its relevance to the fields of cardiovascular medicine in adults and children.
Toxocariasis is a zoonotic disease that occurs when humans are infected by the parasites Toxocara canis or Toxocara cati.
Toxocariasis is highly prevalent in tropical areas, but can also be found in industrialized countries, particularly in rural areas. Clinical presentation can range from asymptomatic infection to more severe disease. Diagnosis of toxocariasis is based on suggestive clinical findings, eosinophilia and a positive serological testing. Albendazole represents the first-line treatment, associated with corticosteroids in case of severe disease.
Here we describe three clinical cases of toxocariasis in order to illustrate the clinical presentation, diagnosis and treatment of this unrecognized disease. The most frequent clinical manifestations are the central retinal granuloma, peripheral retinal granuloma and chronic endophthalmitis.
Secondary complications due to the presence of parasite in the posterior segment of the eye may have significant consequences on visual function. We present the case of a 23 years old patient, admitted for progressive decrease of the right eye BCVA during the last 6 months.
After performing clinical examination and serological tests we established the diagnosis of ocular Toxocariasis. The patient presented a particular form of the disease consisting in the presence of both a central retinal granuloma and a peripheral one. We performed 23G pars plana vitrectomy and membrane peeling.
VA improved as soon as the first month after surgery. To provide an updated insight of concepts regarding the overview, epidemiology, risk factors, clinical manifestations, diagnosis, treatment and prevention of ocular toxocariasis. Perspective of literature review. Review and synthesis of literature about toxocariasiswith interpretation and perspective.
Mild to moderate infections are frequently reported in ocular toxocariasis which usually occurs in children and typically presents as unilateral vision impairment, blindness is common and could present invasion of the retina. There are three groups of presentation of toxocariasis according to the physical examination: Standard diagnosis of ocular toxocariasis is based on the identification of clinical signs, supported by additional diagnostic methods.
Regarding treatment, there is no commonly accepted regimen but most of the authors prefer to use steroids and anthelminthic agents, but nowadays there are no standardized parameters in terms of dosage, duration and route exoftqlmos administration.
Surgery has been recommended in some cases. Toxocariasis is still a problem of public health, particularly in developing countries with an increasing epidemiological burden in terms of morbidity and mortality and most of the authors agree on the utmost relevance of its prevention.
Clinical experience and suspicion of ophthalmologists make an important role in its diagnosis, but always with supportive diagnostic methods. Additional studies should explore new therapeutic options for toxocariasis.
Pediatrician Knowledge of Toxocariasis. Toxocariasisone of a group of parasitic diseases known as neglected parasitic infections, is a disease caused by the larvae of two species of Toxocara roundworms, Toxocara canisfrom dogs, and less commonly Toxocara catifrom cats.
