Advances with the Chinese anthelminthic drug tribendimidine in clinical trials and laboratory investigations.

The anthelminthic drug tribendimidine has been approved by Chinese authorities for human use in 2004, and a first comprehensive review was published in Acta Tropica in 2005. Here, we summarise further advances made through additional clinical trials and laboratory investigations. Two phase IV trials have been conducted in the People's Republic of China, the first one enrolling 1292 adolescents and adults aged 15-70 years and the second one conducted with 899 children aged 4-14 years who were infected with one or multiple species of soil-transmitted helminths. Oral tribendimidine (single 400mg

Diagnostic dilemmas in helminthology: what tools to use and when?

Available data regarding the distribution, prevalence and severity of various diseases are based on the performance and operational characteristics of the diagnostic techniques applied; this is a fact that is particularly apparent in the study of helminth infections. An important lesson learnt from the efforts to rein in dracunculiasis, lymphatic filariasis and schistosomiasis is that the diagnostic approach needs to be changed as further progress is made towards control and ultimate elimination of the disease. This insight prompted the opinion piece presented here, which highlights diagnostic

[Helminth diagnosis in pathologic anatomy].

Most publications devoted to diagnosis of helminths emphasize characteristic parasitological features. Histological feature are seldom described in detail. The purpose of this study was to propose a diagnostic method suitable for use by histologists who, unlike parasitologists, do not visualize the whole worm but rather pieces randomly scattered over a slide. It is relatively easy to distinguish helminths which have smooth muscle, no respiratory or circulatory system, and no coelom from arthropods which have striated muscle, both respiratory and circulatory systems, and coelom. At the adult st

Parasitic infections associated with malignancy and leprosy.

Results of parasitic infections, as revealed by urine and stool examination was significant (P less than 0.05) in 43.3% of patients suffering from different malignant diseases and non significant (P greater than 0.05) in 29.3% of leprosy patients compared to 22% in control subjects. The most prevalent parasites were E. histolytica and G. lamblia. Cryptosporidium occysts were not detected. By stool examination and culture, S. stercoralis larvae were detected only in the malignancy group. The most common parasites occurring concomitantly were A. duodenale and S. stercoralis. By the IFAT, strongy

Effect of mass deworming with antihelminthics for soil-transmitted helminths during pregnancy.

BACKGROUND: Helminthiasis is an infestation of the human body with parasitic worms. It is estimated to affect 44 million pregnancies, globally, each year. Intestinal helminthiasis (hookworm infestation) is associated with blood loss and decreased supply of nutrients for erythropoiesis, resulting in iron-deficiency anaemia. Over 50% of the pregnant women in low- and middle-income countries (LMIC) suffer from iron-deficiency anaemia. Though iron-deficiency anaemia is multifactorial, hookworm infestation is a major contributory cause in women of reproductive age in endemic areas. Antihelminthics …

Costs of integrated mass drug administration for neglected tropical diseases in Haiti.

We conducted a cost analysis of Haiti's Ministry of Public Health and Population neglected tropical disease program, Projet des Maladies Tropicales Negligées and collected data for 9 of 55 communes participating in the May 2008-April 2009 mass drug administration (MDA). The Projet des Maladies Tropicales Negligées Program partnered with IMA World Health and Hôpital Ste. Croix to implement MDA for treatment of lymphatic filariasis and soil-transmitted helminthiasis by using once a year treatment with albendazole and diethylcarbamazine in a population of approximately 8 million persons. Methods …

Как интегрировать (или не интегрировать) вертикальные программы по борьбе с основными забытыми тропическими заболеваниями в странах Африки к югу от Сахары.

Сочетание различных мероприятий в области здравоохранения может свести к минимуму расходы и расширить охват населения мероприятиями. В связи с этим в странах Африки, расположенных к югу от Сахары, поощряется интеграция управления массовыми лекарственными препаратами в целях проведения профилактической химиотерапии (ПХТ) для борьбы с онхоцерциозом, лимфатическим филариатическим филариатозом, шистосомозом, рулетиазом, передаваемым из почвы, и трахомой, поскольку эти забытые тропические заболевания (НТР) во многом совпадают по географическому признаку. Поскольку лишь несколько стран приступили к

Combining the delivery of multiple health interventions has the potential to minimize costs and expand intervention coverage. Integration of mass drug administration is therefore being encouraged for delivery of preventive chemotherapy (PCT) to control onchocerciasis, lymphatic filariasis, schistosomiasis, soil-transmitted helminthiasis, and trachoma in sub-…

[Diagnosis of and anthelminthic therapy for enterobius vermicularis infections during pregnancy: review of the literature and case report].

Intestinal infection due to the pinworm Enterobius vermicularis is the most prevalent helminthiasis in Europe and North America. Humans are the only known reservoir and young children are most often affected. The disease is highly contagious and is transmitted via the faecal-oral route. Insufficient hand hygiene, contaminated bed linens and clothes may play a role in transmission. Clinical symptoms often encompass severe nocturnal anal pruritus, when female worms deposit an abundance of eggs in the perianal region. The infection is diagnosed by applying an adhesive tape on the perianal region,…

[Reactive hypereosinophilia in parasitic diseases].

Hypereosinophilia is often linked to the presence of pluricellular parasites in host tissues. Polynuclear eosinophils are sprung from the bo … osinophilia may be seen. Subsequently, maggots producing myiasis yield to hypereosinophilia too. In helminthiasis, the action of the eosinophil granulocyte is double. In tissues, it destroys the parasite and plays a regulatory role in mastocytes degranulation. Eosinophils which participate in the inflammatory reaction secrete factors which neutralize mediators …

Intestinal helminths and their influence on the indicators of iron status in the elderly.

The intestinal helminthiasis and hematological status was assessed in 100 elderly residents of two low-land communities, one at sea-level and the other at 61; m, equally representative of men and women. These are beth low-income communities. The population showed a 48% helminth infection rate which consisted of hookworm, Trichuris, and Ascaris infection. The prevalence of each of the individual parasites was considered light to moderate and the intensity of infection was generally low in this population. A strong inverse association between intensity of hookworm infection and hemoglobin levels…

[Control of schistosomiasis in Brazil].

The great area with transmission of schistosomiasis in Brazil (11% of the hole country) associated to the focal distribution of the helminthiasis makes the disease control a difficult goal, not only methodologically but also in terms of operation. Since 1976, year when the Special Programme of Schistosomiasis Control was begun, it has been possible to develop regular activities of control. Since then, these activities are conducted in a vertical programme, which is being maintained till it will be possible to get to a prevalence of five percent or under this value. The regular checking of prev…

MALDI-TOF mass spectrometry as a diagnostic tool in human and veterinary helminthology: a systematic review.

BACKGROUND: Matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry (MS) has become a widely used technique for the rapid and accurate identification of bacteria, mycobacteria and certain fungal pathogens in the clinical microbiology laboratory. Thus far, only few attempts have been made to apply the technique in clinical parasitology, particularly regarding helminth identification. METHODS: We systematically reviewed the scientific literature on studies pertaining to MALDI-TOF MS as a diagnostic technique for helminths (cestodes, nematodes and trematodes) of

Intestinal parasitism--protozoa and helminths--in primates at the Barcelona Zoo.

The faunistic results regarding intestinal parasitism by protozoa and helminths in 21 primate species (three Cebidae, thirteen Cercopithecidae, one Hylobatidae, one Lemuridae, three Pongidae) are reported. The primate species were housed in four separate galleries. Six faecal samples of each host species were subjected to coprological analysis. Fifteen parasite species were detected: 11 protozoa (Entamoeba coli, E. chattoni, E. hartmanni, Iodamoeba bütschlii, Endolimax nana, Giardia intestinalis, Chilomastix mesnilii, Enteromonas hominis, Trichomonas intestinalis, Balantidium coli, and Blastoc
