Total anthelmintic failure to control nematode parasites of small ruminants on government breeding farms in Sabah, East Malaysia

Chandrawathani P, Yusoff N, Wan LC, Ham A, Waller PJ

Vet Res Commun, 2004 Aug;28(6):479-89.

PMID: 15509022

Government-owned small-ruminant breeding farms in Malaysia provide the source of sheep and goats to smallholder farmers in the country. In the eastern Malaysian state of Sabah, high-level stock losses have been recorded on these farms for several years, frequently accompanied by clinical signs indicating pathogenic levels of infections with the nematode parasite Haemonchus contortus. This suggests that their dependence on chemotherapy to control parasite infections had failed. Accordingly, tests for anthelmintic efficacy using the faecal egg count reduction test (FECRT) on the range of drugs used to control nematode parasites were carried out on the five government small-ruminant breeding farms in Sabah. These tests showed a total failure of the benzimidazole, imidothiazole, macrocyclic lactone and salicylanilide groups of anthelmintics to control H. contortus infections of sheep and goats on all farms. Drastic changes in animal management need to be made in an attempt to deal with this situation, for which suggestions are made.

Fulltext The effect of long-term deworming on the prevalence of soil-transmitted helminthiases in Malaysia

Kan SP

Med J Malaysia, 1985 Sep;40(3):202-10.

PMID: 3842715

Once-yearly, mass deworming with broad spectrum anthelmintics over a period of five years among four types of communities in Malaysia resulted in an overall education in the prevalence of soil-transmitted helminthiases by one-third to two-thirds. The reduction in prevalence of infection was highest among inhabitants in semi-urban settlements (65.5%), followed by those in the rural estates (53.0%) and high-rise flats (43.9%). Soil-transmitted helminthiases were only reduced by 35.5% in the urban slums. Reduction in infection with Trichuris trichiura was better than that with Ascaris lumbricoides whereas hook-infection was completely eliminated in some of the communities surveyed. The reduction in prevalence ofsoil-transmitted helminthiases by long-term, once-yearly deworming alone, without other supplementary interventions, reinforces the potential and feasibility of regular mass-deworming as an immediate and effective measure for the control ofsoil-transmitted helminthiases. This is of great public health significance especially in highly endemic communities where some form of intervention is urgently needed and facilities for other control measures such as the improvement of environmental sanitation and nutritional status and health education are neither feasible nor possible nor immediately available.

Fulltext Symptomatic chronic strongyloidiasis in children following treatment for solid organ malignancies: case reports and literature review

Norsarwany M, Abdelrahman Z, Rahmah N, Ariffin N, Norsyahida A, Madihah B, et al.

Trop Biomed, 2012 Sep;29(3):479-88.

PMID: 23018511

Strongyloidiasis is an infection caused by the intestinal nematode Strongyloides stercoralis. Infected healthy individuals are usually asymptomatic, however it is potentially fatal in immunocompromised hosts due to its capacity to cause an overwhelming hyperinfection. Strongyloidiasis could be missed during routine screening because of low and intermittent larval output in stool and variable manifestations of the symptoms. We present two cases of strongyloidiasis occurring in children with solid organ malignancies suspected to have the infection based on their clinical conditions and treatment history for cancer. Both patients were diagnosed by molecular and serological tests and were successfully treated. Thus, strongyloidiasis in patients undergoing intensive treatment for malignancies should be suspected, properly investigated and treated accordingly.

PMID: 23202608

Trichuris dysentery syndrome is caused by Trichuris trichiura which contributes to one of the most common helminthic infections in the world. It is associated with heavy colonic infection that manifests as mucoid diarrhoea, rectal bleeding, rectal prolapse, iron deficiency anaemia, and finger clubbing. Here, we report a case of trichuris dysentery syndrome complicated with severe chronic iron deficiency anaemia in a 4-year-old girl who required blood transfusion. The nematode was visualized on stool microscopic and colonoscopic examination. A longer duration of anti-helminthic treatment is required to achieve effective and better outcome.

Resistance to benzimidazole anthelmintics by Haemonchus contortus in goats in peninsular Malaysia

Rahman WA

Vet Parasitol, 1994 Oct;55(1-2):155-7.

PMID: 7886916

A previous study had suggested that local strains of goat trichostrongyles, comprising largely Haemonchus contortus, might have developed resistance to benzimidazole anthelmintics. A trial involving 18 goats was conducted to confirm this. There was a significant (P < 0.01) reduction in worm burdens in goats given levamisole, but this was not so for those animals given albendazole, fenbendazole, oxfendazole and mebendazole (P > 0.05).

Fulltext Prevalence and associated factors of Schistosomiasis among children in Yemen: implications for an effective control programme

Sady H, Al-Mekhlafi HM, Mahdy MA, Lim YA, Mahmud R, Surin J

PMID: 23991235 DOI: 10.1371/journal.pntd.0002377

BACKGROUND: Schistosomiasis, one of the most prevalent neglected tropical diseases, is a life-threatening public health problem in Yemen especially in rural communities. This cross-sectional study aims to determine the prevalence and associated risk factors of schistosomiasis among children in rural Yemen.

METHODS/FINDINGS: Urine and faecal samples were collected from 400 children. Urine samples were examined using filtration technique for the presence of Schistosoma haematobium eggs while faecal samples were examined using formalin-ether concentration and Kato Katz techniques for the presence of S. mansoni. Demographic, socioeconomic and environmental information were collected via a validated questionnaire. Overall, 31.8% of the participants were found to be positive for schistosomiasis; 23.8% were infected with S. haematobium and 9.3% were infected with S. mansoni. Moreover, 39.5% of the participants were anaemic whereas 9.5% had hepatosplenomegaly. The prevalence of schistosomiasis was significantly higher among children aged >10 years compared to those aged ≤ 10 years (P<0.05). Multivariate analysis confirmed that presence of other infected family member (P<0.001), low household monthly income (P = 0.003), using unsafe sources for drinking water (P = 0.003), living nearby stream/spring (P = 0.006) and living nearby pool/pond (P = 0.002) were the key factors significantly associated with schistosomiasis among these children.

CONCLUSIONS/SIGNIFICANCE: This study reveals that schistosomiasis is still highly prevalent in Yemen. These findings support an urgent need to start an integrated, targeted and effective schistosomiasis control programme with a mission to move towards the elimination phase. Besides periodic drug distribution, health education and community mobilisation, provision of clean and safe drinking water, introduction of proper sanitation are imperative among these communities in order to curtail the transmission and morbidity caused by schistosomiasis. Screening and treating other infected family members should also be adopted by the public health authorities in combating this infection in these communities.

PMID: 33612805

The health impact of a Malaysian national helminth control program which provided school-based anthelmintic chemotherapy from 1974 to 1983 was re-visited after three decades post MDA and associated risk factors amongst urban poor communities identified. Stool samples collected were screened using the formalin ethyl-acetate concentration technique recovered at least one species of helminth and/or protozoan. Despite a steady decline observed between 1974-1983 however, post MDA infections continue to persist in pockets of communities moderately (18.9%; n=39/206) with higher infection recorded amongst PPR flat residents (22.5%, n=16/71). Among risk factors identified, waste management method was the primary factor for Ascaris lumbricoides infections (n=33; 16.0%), whereas age, education, employment and source of drinking water were significant risk factors for cryptosporidiosis. Despite the government's efforts to improve health through the provision of basic amenities to the general public, higher prevalence values amongst PPR flat dwellers suggests the need to implement targeted chemotherapeutic treatment of, once a year deworming as recommended by World Health Organization when the baseline prevalence of soil-transmitted helminth infections in the community is over 20%, in addition to preventive measures though improvements in health awareness programs and improved waste management methods.

Neurocysticercosis, infection of the central nervous system (CNS) by larvae of the pork tapeworm Taenia solium, is the commonest neuroparasitic infection in humans. However in countries as in Malaysia it poses a diagnostic problem as the disease in not seen amongst the local population; however with the arrival of immigrant workers, a number of cases have recently been diagnosed. There were 3 cases of neurocysticercosis reported in our centre over the last 5 years.

PMID: 7886917

The anthelmintic efficacy of benzimidazoles, levamisole, closantel, ivermectin and moxidectin was evaluated on an institutional farm in Malaysia using faecal egg count reduction tests, controlled slaughter trials and an in vitro egg hatch assay. The results of this study indicated simultaneous resistance of Haemonchus contortus against benzimidazoles and ivermectin and of Trichostrongylus colubriformis against benzimidazoles and levaminsole on the same farm. Moxidectin was effective against the ivermectin resistant H. contortus.

Mahendra Raj S

Southeast Asian J. Trop. Med. Public Health, 1998 Mar;29(1):112-7.

PMID: 9740282

A cohort of one hundred 8-9 year old school children in Northeastern Peninsular Malaysia underwent stool examination, weight and height measurements. Seventy-three children were infected with Ascaris lumbricoides and/or Trichuris trichiura. All infected children were treated with albendazole at baseline, 6 months and 9 months. Measurements were repeated on all but 2 children at 1 year. Repeat stool examination (n = 94) at 1 year revealed a marked reduction in the level of Ascaris infection and a modest reduction in Trichuris infection. There was no difference in net growth between treated children and uninfected controls. Post-hoc analysis by gender however revealed that infected girls (n = 33) experienced significantly higher increments in weight, height and weight for age. Furthermore, children found to be infected at baseline level but worm free at follow-up, were observed to have experienced greater increments in height and height for age. The evidence suggests that periodic antihelminthic treatment may have a positive effect on the growth of subsets of pre-adolescent children but it is emphasised that further work is required to validate these findings.

Human intestinal parasitic infection: a narrative review on global prevalence and epidemiological insights on preventive, therapeutic and diagnostic strategies for future perspectives

Wong LW, Ong KS, Khoo JR, Goh CBS, Hor JW, Lee SM

Expert Rev Gastroenterol Hepatol, 2020 Nov;14(11):1093-1105.

PMID: 32755242 DOI: 10.1080/17474124.2020.1806711

INTRODUCTION: Intestinal parasitic infection (IPI) is a global health concern among socioeconomically deprived communities in many developing countries. Many preventative strategies have been deployed to control IPI, however, there is a lack in standards on the techniques used to diagnose and monitor the prevalence of IPI.

AREAS COVERED: The present article will review the diseases associated with IPI and discuss the current IPI control strategies such as the water, sanitation, and hygiene (WASH) interventions, community-led total sanitation (CLTS) approach, and regular anthelminthic treatments. For the first time, this review will also evaluate all currently practised diagnostic techniques for the detection of intestinal parasites and provide insights on future IPI control strategies.

EXPERT OPINION: Advanced and improved diagnostic methods such as qPCR coupled with a high-resolution melting curve, aptamers, biosensors, and detection of extracellular vesicles can be used for detection of IPI. Vaccination against intestinal parasites can be made available to increase antibodies to interfere with the blood-feeding process by the parasites, which subsequently reduces the reproductive rates of the parasites. These methods collectively can serve as future management strategies for intestinal parasitic infections.

Growth reduction among primary schoolchildren with light trichuriasis in Malaysia treated with albendazole

Tee MH, Lee YY, Majid NA, Noori NM, Raj SM

Southeast Asian J. Trop. Med. Public Health, 2013 Jan;44(1):19-24.

PMID: 23682433

We studied asymptomatic primary schoolchildren in northeastern Malaysia with light to moderate trichuriasis to determine the effect of albendazole treatment on growth rates and TNF-alpha levels. Thirty-seven schoolchildren aged 6-7 years with stool samples positive for Trichuris trichiura and negative for other geohelminths and protozoa were randomized to receive albendazole 400 mg or a placebo daily for 2 days. Anthropometric parameters at baseline, 3, 6 and 12 months were compared between the 2 groups. The placebo group had a significantly greater increase in height (p = 0.04) than the albendazole treatment group. There were no significant differences in urinary TNF-alpha levels (p = 0.8) between the 2 groups and no significant changes between baseline and 1 month post-treatment levels. Further studies are needed to determine the etiology of this apparent association between the albendazole treatment group and the delay in growth rate at 6 months post-treatment.
