Rheumatic manifestations of parasitic diseases.

OBJECTIVES: To consolidate the spectrum and frequency of parasite-related rheumatic syndromes, which have largely been regarded as exceedingly rare by the general medicine, infectious disease, and rheumatology literature. METHODS: A MEDLINE search was performed for articles on rheumatic syndromes related to parasitic infections published from 1966 through December 2000. Identified articles included clinical and epidemiologic studies describing cases of rheumatic syndromes associated with verified parasitic infection. RESULTS: Rheumatologic syndromes, including inflammatory arthritis, inflammatory myositis, and vasculitis, have been described among multiple different parasite infections of all parasitic divisions, including Protozoa, Nematoda, and Platyhelminthes. Individual parasitic divisions are often associated with particular rheumatic syndromes, such as reactive arthritis and spondyloarthropathy, inflammatory or infectious myositis, and reactive or parainfectious vasculitis. CONCLUSIONS AND RELEVANCE: Parasitic infection may underlie the clinical presentation of some rheumatic conditions. Given the continued and growing number of patients at risk for parasitosis by virtue of their country of origin, travel habits, and an immunocompromised state, potential parasitosis must be considered in patients undergoing evaluation for rheumatic complaints.

Cysteine proteinase inhibitors as therapy for parasitic diseases: advances in inhibitor design.

Clan CA (papain-like) cysteine proteinases of protozoan parasites are validated targets for the rational design of new anti-parasitic chemotherapies. Peptidyl and peptidomimetic proteinase inhibitors of differing chemistries limit parasite survival in vitro and in vivo. Also, the development of activity-based affinity labels has enabled the identification and characterization of potential cysteine proteinase targets in situ. This article reviews the biology and physicochemistry of parasite proteinases and the ongoing design of peptidyl and non-peptidyl inhibitors to generate anti-parasitic compounds of greater efficacy with decreased toxicity to the host.

[Research on intestinal parasitic diseases in dogs of the city of Rome].

A survey on the diffusion of intestinal parasites of dogs in the town of Rome. The results of a survey on the diffusion of cestodes and nematodes in a hundred dogs in Rome are reported. The dogs were subjected to fecal examinations --- using both the flottation method and the McMaster method -- and to the post-mortem examination of the intestine. At post-mortem examination 25 dogs were found parasitized by one or more species of nematodes, 19 by one or more species of cestodes and 12 both by cestodes and nematodes for a total of 56 animals parasitized. The parasites were identifed with the following frequency: Dipylidium caninum 28 per cent, Toxocara canis 17 per cent, Uncinaria stenocephala 15 per cent, Trichuris vulpis 10 per cent, Toxascaris leonina 9 per cent, Taenia pisiformis 4 per cent, Echinococcus granulosus 2 per cent, Ancylostoma caninum, T. hydatigena and Mesocestoides lineatus 1 per cent each. The most frequent parasite found in stray dogs was U. stenocephala (33.3 per cent) while among the dogs with owners the most frequent one was D. caninum (31.8 per cent) which was also identified most frequently in dogs over a year of age (31.1 per cent). The dogs under one year of age were more often affected by T. canis (43.7 per cent). In the paper a review of similar Italian surveys is also given.

[Parasitic diseases and fecal hazards: diseases due to helminths].

Ascaris, trichocephalus, hookworm, necator and anguillula--all of which are human parasites--are closely linked to fecal peril and especially prevalent among populations in developing countries, where fecal hygiene is insufficient or lacking. Epidemiological surveys seeking to evaluate the frequency of the various intestinal helminths are usually intermittent, few in number, and especially difficult to compare because of the different coprological techniques used. However this may be, the respective prevalence of these worms depends on geographical, climatic, economic, and human conditions. Their effect on health is not negligible, especially on children's health and in particular when malnutrition also occurs. To fight effectively against these verminoses, education and economic development must be promoted, but the present situation of the economy in most developing countries is postponing indefinitely the fight against fecal peril especially as its control is not seen as a priority.
