Taeniosis and cysticercosis in Serbia, 1990-2018: Significance of standard of living.

OBJECTIVES: As is the case for all of Southeast Europe, Serbia is an area traditionally endemic for Taenia saginata and Taenia solium infections. This study was performed to analyse the epidemiological data on taeniosis and cysticercosis in Serbia for the period 1990-2018. METHODS: Data on cases of T. saginata and T. solium infection were collected via a systematic search of published articles, the grey literature, and official reports, as well as by performing clinical observational studies of patients treated in the departments for infectious diseases of hospitals and university clinics in Serbia. RESULTS: A total of 212 cases of taeniosis were reported, all between 1997 and 2004 when taeniosis was notifiable (incidence range 0.04-0.9/100 000 population/year). From 1990 to 2018, 170 cases of cysticercosis (all but one of neurocysticercosis), were registered (incidence range 0-0.29/100 000 population/year), with a strong decrease since 2000 and a single case in the last 9 years. The annual number of cases of both taeniosis (Pearson's r = 0.914, p = 0.001) and cysticercosis (Pearson's r = 0.582, p = 0.014) correlated with the consumer price index. CONCLUSIONS: In Serbia, T. saginata and T. solium infections are autochthonous but occur only sporadically. However, the potential for re-emergence exists, depending on the socio-economic state of the country.

Epidemiology of taeniosis/cysticercosis in Europe, a systematic review: eastern Europe.

BACKGROUND: Taenia solium and Taenia saginata are food-borne parasites of global importance. In eastern Europe only fragmented information is available on the epidemiology of these zoonotic parasites in humans and animal populations. In particular for T. solium, on-going transmission is suspected. The aim of this systematic review was to collect the available data and describe the current knowledge on the epidemiology of T. solium and T. saginata in eastern Europe. METHODS: Literature published in international databases from 1990 to 2017 was systematically reviewed. Furthermore, local sources and unpublished data from national databases were retrieved from local eastern European experts. The study area included 22 countries. RESULTS: Researchers from 18 out of the 22 countries provided data from local and unpublished sources, while no contacts could be established with researchers from Belarus, Kosovo, Malta and Ukraine. Taeniosis and human cysticercosis cases were reported in 14 and 15 out of the 22 countries, respectively. Estonia, the Former Yugoslav Republic of Macedonia, Lithuania, Moldova, Poland, Romania, Serbia, and Slovakia reported cases of porcine cysticercosis. Croatia, Czech Republic, Estonia, Former Yugoslav Republic of Macedonia, Moldova, Poland, Romania, Serbia, Slovakia, and Ukraine reported bovine cysticercosis. CONCLUSIONS: There is indication that taeniosis and cysticercosis are present across eastern Europe but information on the occurrence of T. solium and T. saginata across the region remains incomplete. Available data are scarce and species identification is in most cases absent. Given the public health impact of T. solium and the potential economic and trade implications due to T. saginata, notification of taeniosis and human cysticercosis should be implemented and surveillance and notification systems in animals should be improved.

HUMAN SUBCUTANEOUS DIROFILARIASIS - CASE REPORT.

INTRODUCTION: Human dirofilariasis is a zoonotic disease caused by Dirofilaria repens and Dirofilaria immitis. It usually presents as a nodular lesion in the lung, subcutaneous tissues or eyes. In animals, dirofilariasis is a very common disease with serious cardiovascular and respiratory manifestations. If adequate therapy is not given at the beginning ofthe disease, dirofilariasis can lead to animal death. On the contrary, human dirofilariasis is frequently mild, sporadic and asymptomatic disease. Complications in humans are very rare. In Europe, human dirofilariasis is a very rare zoonotic disease even in endemic areas such as Italy, Spain and the Mediterranean. CASE REPORT: The authors reported the case of a 43-year-old male with a subcutaneous nodule caused by Dirofilaria repens. The patient who lives in Budva, Montenegro, had a nodule in the right-hand side of the anterior abdominal walljust below the sternum with maximum diameter of 3 cm. His health condition was good and all laboratory analyses were normal. The lesion was surgically removed and the histopathological examination confirmed the parasitic infection by Dirofilaria repens. After surgical excision, the patient was treated with dual antimicrobial therapy (100 mg doxycycline per os twice a day for 28 days and 200 mg albendazole per os twice a day for 10 days). CONCLUSION: It is very difficult to make the diagnosis of a subcutaneous nodule. The difficulties arise in the differential diagnosis because subcutaneous nodules are suspected to be malignant neoplasm or other pathologies such as tuberculosis, fungal infections, sebaceous cysts, hamartomas, abscesses, and so on. Although human dirofilariasis is a rare disease, the number of reported cases has recently been increasing worldwide.
