The Latin hypercube method was used to represent the uncertainty surrounding the input parameters. More accurate data on CE prevalence in humans particularly undiagnosed or asymptomatic cases and better methods to estimate productivity losses in animals are needed. CE continues to affect certain areas of Spain, despite several control initiatives since Given the high economic burden of CE, additional funding is needed to reduce human and animal infection rates through improved disease surveillance, regular treatment of dogs and greater cooperation between agencies.
Introduction Cystic echinococcosis CE or hydatid disease is a zoonotic infection caused by the larval stage of the taeniid tapeworm Echinococcus granulosus.
The parasite's life cycle is maintained through dogs which harbour the adult worm in their small intestine and a range of domestic livestock that serve as intermediate hosts. Ungulates hoofed animals can become infected by grazing on pasture contaminated with dog faeces. Ingested eggs hatch inside the intestine, penetrate the gut wall and are carried by the bloodstream to different organs and tissues mainly the liver and lungs where they develop into cysts metacestodes that can eventually cause severe pathological damage.
Humans can become infected by ingesting eggs through consuming contaminated food or water or from handling the faeces of infected dogs.
As in other countries of the Mediterranean basin, CE is endemic in Spain. Since the mids, a number of prevention and control programmes to reduce E. These programmes have led to a considerable decrease in human and animal CE infection rates.
A recent survey showed human CE annual incidence rates in the range of 1. Surveillance of CE in livestock is carried out through routine postmortem examination in all national slaughterhouses, with detected cases reported to the Spanish Food Safety Agency.
Animal-associated economic losses arise from decreases in carcass weight, milk production and fertility rates, and from increased condemnation of viscera. However, cost estimates at a national scale are lacking. The aim of this study was to estimate the overall economic losses due to human and animal CE in Spain in Methods Human epidemiological parameters The human epidemiological parameters used in the analysis included diagnosed cases in males and in females ; undiagnosed or asymptomatic cases; and diagnosed cases with surgery.
The number of reported CE cases by age and gender was obtained from the epidemiology surveillance network22 and was used to estimate the productivity losses in humans see below.
We assumed that the proportion of reported cases and the frequency of different types of treatment were uniform across age and gender. The burden associated with recurrence was captured in the "per intervention cost"of each surgical case.
Therefore, we assumed that the prevalence of undiagnosed or asymptomatic cases was proportional to that estimated in a study conducted in the Florida district of Uruguay. In that study, the prevalence of undiagnosed disease was estimated to be 1. However, because of the large uncertainty in this estimate, we used a triangular distribution with a mode of 0.
Diagnosed reported cases, as well as undiagnosed or asymptomatic cases, were assumed to have a reduction in productivity of 2. We assumed that the same level of lost opportunity applied to people who were asymptomatic, undiagnosed or diagnosed.
Estimation of human costs Costs incurred because of CE in humans were divided into direct and indirect costs. Direct cost estimates included separate calculations for surgical and nonsurgical patients. In both cases, a cost-per-patient estimate was calculated using the itemized prices for typical care, and the expected percentage of use for specific services, procedures and treatments.
Average wages according to sex and age were obtained from the Wage Distribution Survey of the National Statistics Institute.
All the selected patients had sent to the Pathology Department: gallbladder, cyst and pericyst. The main results of the study revealed no evidence to confirm the hypothesis that the gallbladder is a hydatid reservoir. Out of the 35 cases, in 16 we observed the tendency to include hepatic biliary ducts in the pericyst or the formation of new canals which lead to the formation of biliary fistulas.
Although it is a benign pathology, the evolution of hepatic hydatidosis can lead to severe complications and a low quality of life for the patient, both before and after surgery.
Better knowledge of the pathology behind the local evolution of the disease can influence the therapeutic approach. Keywords: 1. In: Cook GC, ed.
