Selective mass treatment with ivermectin to control intestinal helminthiases and parasitic skin diseases in a severely affected population. To assess the short-term and long-term impact of selective mass treatment with ivermectin on the prevalence of intestinal helmintiassi and parasitic skin diseases in an economically depressed community in north-east Brazil.

An intervention was carried out in a traditional fishing village in north-east Brazil where the population of is heavily affected by ectoparasites and enteroparasites.

The prevalence of intestinal helminths was determined by serial stool examination and the prevalence of parasitic tratmaiento diseases by clinical inspection. A total of people out of a target population of were treated at baseline. If ivermectin was contraindicated, participants were treated with albendazole or mebendazole for intestinal helminths or with topical deltamethrin for ectoparasites. Follow-up examinations were performed at 1 month and 9 months after treatment.

Prevalence rates of intestinal helminthiases before treatment and at 1 month and 9 months after mass treatment were: Prevalence rates of parasitic skin diseases before treatment and 1 month and 9 helmintiasls after mass treatment were: Adverse events occurred in 9.

They were all of mild to moderate severity and were transient. Mass treatment with ivermectin was an effective and safe means of reducing the prevalence of most of the parasitic diseases prevalent in a poor community in north-east Brazil.

The effects of treatment lasted for a prolonged period of time. Las tasas de prevalencia de las helmintiasis intestinales antes del tratamiento y al cabo de un mes y 9 meses del tratamiento masivo fueron las siguientes: El tratamiento tuvo efectos prolongados.

The morbidity associated with these parasites is strongly related to parasite burden; it includes nutritional disorders, such as stunting and anaemia; deficient cognitive tratamoento and impaired performance at school 145. The disease burden is particularly high in developing countries and among school-age children 16. Because it is difficult to eliminate the factors that make individuals vulnerable to infection with intestinal helminths, such as a lack of sanitation, poor hygiene and overcrowding, mass treatment with a broad spectrum anthelminthic drug is considered to be the key strategy for controlling morbidity among impoverished populations 1346.

Parasitic skin diseases also affect several hundred million individuals worldwide 78. In particular, tungiasis, pediculosis, scabies and cutaneous larva migrans have an important impact on society as a whole and on the mental health of the individual.

However, these skin diseases are rarely acknowledged as trafamiento health problems 8 WHO recommends four drugs for the control of intestinal nematodes, namely albendazole, mebendazole, levamisole, and pyrantel Although ivermectin is known to be a safe and potent broad spectrum anthelminthic 1516 that also has a proven effect against different ectoparasites, it is recommended for the treatment of only some filarial diseases.

A few randomized or open trials have shown that ivermectin has a high efficacy when used to treat skin diseases such as scabies 17 helmintiazis, 18head lice 19and cutaneous larva migrans Ivermectin is a comparatively cheap drug, and some have suggested that it could be used to treat individuals infected by a number of parasites in situations where specific diagnoses are difficult to establish due to trataminto lack of appropriate health infrastructure Because the simultaneous occurrence of intestinal and skin parasites is common among resource-poor populations, ivermectin may be the ideal treatment to control ectoparasites and enteroparasites at the community level.


To assess the effectiveness of ivermectin in such a setting, we performed an intervention study based on mass treatment with ivermectin in a poor fishing community heavily affected by intestinal helminthiases and parasitic skin diseases.

Meaning of “helmintiasis” in the Spanish dictionary

Study area and population. The village is situated on sand dunes near the coast, and the people mainly depend on fishing for their livelihood. The community comprises families, and there are a total of inhabitants. The population is poor; streets are not paved; and many houses are built on sandy soil. Each household in the community was visited, and plastic vials for stool specimens were distributed. A staff member visited the households to collect the specimens. The samples were collected in plastic vials without preservatives, and they were helmintiais in a field laboratory on the same day.

Stool samples were examined before treatment and 4 weeks after treatment. To assess the long-term effect of mass treatment with ivermectin, another follow-up examination was performed 9 months after treatment.

Stool samples were processed by the sedimentation method as described by Hoffman et al. After 24 hours, the sediment is collected from the bottom of the receptacle with a pipette.

In this study, the method was adapted to use a centrifuge instead of spontaneous sedimentation. Samples were centrifuged for 3 minutes at rpm. One slide per faecal sample was prepared. Strongyloides stercoralis larvae and hookworm larvae were differentiated using established morphological criteria If the stool sample was negative for S.

Quality control was performed during baseline and the follow-up examinations. If the results diverged, a new slide was prepared from the original sample and read by an expert microscopist who was blind to the previous results. To recruit participants with parasitic skin diseases, all households were visited twice by the same investigator TW. Each member of the family was thoroughly examined for the presence of scabies, tungiasis, head lice and cutaneous larva migrans.

Diagnoses were made clinically. Pubic lice were not looked for.

Body lice, ticks and myiasis do not occur in the study area. Parasitic skin diseases were defined as shown in Box 1. Selective mass treatment was performed as follows.

The target population was defined as all individuals from households where at least one individual was found to be infected with at least one intestinal helminth or one ectoparasite species. The dose was repeated after 10 days. Contraindications for administration of ivermectin were: Women who were pregnant or breastfeeding at baseline were treated at the end of the study; breastfeeding women were treated at this time only if their children had been weaned.

All oral drugs were administered under supervision. Participants were instructed to use the lotion for three consecutive nights on their head in cases of pediculosis or their body in cases of scabies. An adverse event was defined as the occurrence of symptoms or signs after treatment regardless of whether a pharmacological relation to the drug was assumed.

Details of the adverse events were recorded as signs, symptoms, the date and time the event started and ended, how long it occurred after tratamieto the drug, the heljintiasis of the event, the severity of the event, the action taken by the participant, and the outcome.

Data were entered into a database twice using EpiInfo software version 6. The c 2 test was used to determine the significance of differences between relative frequencies. In preparation for the study, several community meetings were held, and the objectives of the study were explained. The representatives decided unanimously tratamient the community should support the study. Ethical clearance was obtained from the institution legally responsible for monitoring public health interventions using registered drugs, helnintiasis this case tratxmiento ethical committee of Cascavel Municipality.


Before an individual was included in the study, informed oral consent was obtained. In the case of minors, carers were asked for consent. The study was conducted in accordance with good clinical practice and the Declaration of Tratamienfo as amended in The target population consisted of individuals with a mean age There were males At baseline, stool samples from inhabitants At the first follow-up visit, stool samples from individuals At baseline, individuals At the time of first follow-up people were examined The number of individuals examined and the number of those who received ivermectin, albendazole, mebendazole, or topical deltamethrin are shown in Table 1.

A total of 88 individuals 41 females, 47 males; mean age Prevalence rates of intestinal helminthiases at baseline are shown in Table 2. Prevalence rates of parasitic skin diseases at baseline and during follow-up are shown in Table 3.

Cutaneous larva migrans was found in four patients at baseline, but none was found to be infected during follow-up. The prevalence of tungiasis remained unchanged 1 month after mass treatment. The relative reduction in prevalence rates obtained 9 months after selective mass treatment is shown in Table 4.

Ivermectin was well tolerated. After a total of doses of ivermectin, adverse events were reported in 85 9. All events were of mild or moderate severity. Two events were considered completely unrelated, and 12 were unlikely to be related to the drug data not shown.

After the second ivermectin dose, significantly fewer adverse events were reported 21 individuals, 4. Eight events were considered to be probably related to treatment, and 11 were considered to be possibly related. One case was tdatamiento, and two other events were unlikely to have been related to the drug. The majority of events occurred in individuals with helminth eggs present in stool samples while having treatment.

In developing countries, intestinal helminthiases and parasitic skin diseases are not only highly prevalent but also associated with important morbidity 111 What is less well known is that intestinal helminthiases and parasitic skin tgatamiento commonly coexist in resource-poor communities, and many individuals are concomitantly infected with enteroparasites and ectoparasites.

Mass treatment with a broad spectrum anthelminthic drug is considered to be an effective means of controlling intestinal helminths at the population level 134. The benefit tratamkento periodic treatment with drugs such as albendazole and mebendazole has been shown clearly in terms of a reduction in worm burden and morbidity 1528 At least in children, regular treatment has been shown to reduce the parasite load to such a low level that helminth-associated morbidity may completely disappear 3 Until now, similar data on parasitic skin diseases have been scanty, although it may be hhelmintiasis that mass treatment would reduce the prevalence of ectoparasitoses and their associated morbidity 2130 The key to successfully controlling morbidity associated with ectoparasites and enteroparasites is to use a drug with a high efficacy against all types of parasites expected to occur among impoverished populations.

Ivermectin is a promising candidate for such an approach. It is highly effective against a number of intestinal nematodes, and it is considered the drug of choice for treating strongyloidiasis 1.

It is also effective against scabies, pediculosis and cutaneous larva migrans 17192032 ,
