Clinical assessment of coded Unani formulation D-worm and mebandazole for the treatment of hook worm, roundworm and whip worm.

A case control, multicenter, prospective randomized two arm parallel group clinical trials was conducted on 190 patients. The main objective of this study is to provide comparative efficacy results of both trialed medicines. The comparison was done in between herbal medicine D-Worm and Mebandazole allopathic drug for the treatment of helminthiasis. All the rules of GCP (Good Clinical Practices) were followed including clinical history, clinical presentation, examination findings and stool tests. Stool D/R and Parasite antigen tests were performed before and after treatment. The comparison of symptoms were also done including the improvement in abdominal pain, worms in stool, anal itching, nausea and vomiting, loss of appetite, and fatigue etc. The data on clinical proforma was gathered and subjected to statistical analysis. Parasite specific antigen test and stool D/R is considered as gold standard test for the diagnosis and confirmation of helminthes infection. Different parameter i.e. age, sex, and other clinical sign and symptoms were studied and compared between two treatment groups (Control and Test groups) at baseline and end of therapeutic application. Consent of patient was taken at first before the start of examination. Majority of the patients (90%) included in this study group get cured after herbal treatment. The statistical analysis used for the assessment of the effect of the treatment also showed significant improvement after treatment.

The potential economic value of a hookworm vaccine.

Hookworm infection is a significant problem worldwide. As development of hookworm vaccine proceeds, it is essential for vaccine developers and manufacturers, policy makers, and other public health officials to understand the potential costs and benefits of such a vaccine. We developed a decision analytic model to evaluate the cost-effectiveness of introducing a hookworm vaccine into two populations in Brazil: school-age children and non-pregnant women of reproductive age. Results suggest that a vaccine would provide not only cost savings, but potential health benefits to both populations. In fact, the most cost-effective intervention strategy may be to combine vaccine with current drug treatment strategies.

Uncinaria stenocephala: assessment of antigens for the immunodiagnosis of canine uncinariosis.

Although Uncinaria stenocephala is the most frequent hookworm in the intestine of dogs from Northern, Central and Southern Europe, little is known about its host-parasite relationship. Three groups of sera from dogs (Group 1: dogs naturally infected only by U. stenocephala; Group 2: helminth-free dogs at necropsy, and Group 3: dogs parasitized by other helminths) were analyzed by ELISA using U. stenocephala antigens from adult worms (somatic and excretory-secretory antigens) and from L3 larvae (somatic antigens). All three sources of antigens were found to be suitable for immunodiagnosis of canine uncinariosis with up to 90% efficacy. However, an analysis to assess the diagnostic value of the different antigens demonstrated that the adult excretory-secretory antigens had a higher diagnostic efficacy (96.7%), indicating that this is the best antigen source for the diagnosis of Uncinaria infection.
