Trop Biomed, 2012 Dec;29(4):626-31.

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.

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.

Fulltext Diphyllobothriasis: the first case report from Malaysia

Rohela M, Jamaiah I, Chan KW, Yusoff WS

Southeast Asian J. Trop. Med. Public Health, 2002 Jun;33(2):229-30.

PMID: 12236417

Diphyllobothriasis is a disease caused by infection with adult tapeworms of the genus Diphyllobothrium. Humans acquire the infection by consuming the raw or inadequately cooked flesh, roe, liver, or other organs of infected fish. Diphyllobothrium latum infection has not been reported in Malaysia; we are reporting the first case. The patient was a 62 year old Chinese male seen at the outpatient clinic with complaints of watery stools and slight abdominal discomfort for four days. Physical examination was normal. He was treated for diarrhea. Two days after treatment, he passed out intact off-white proglottids in his stool. Diphyllobothriasis was confirmed by examination of these gravid proglottids; typical operculated eggs were seen after rupturing the gravid proglottids. The patient had a history of eating sashimi (Japanese raw fish). He was treated with a single dose of praziquantel and had been well since.

Cutaneous larva migrans in Hospital Kuala Lumpur, Malaysia: rate of correct diagnosis made by the referring primary care doctors

Yap FB

Trans R Soc Trop Med Hyg, 2011 Jul;105(7):405-8.

PMID: 21600621 DOI: 10.1016/j.trstmh.2011.04.002

A retrospective study was undertaken to determine the clinical features of cutaneous larva migrans (CLM) seen in the Department of Dermatology, Hospital Kuala Lumpur (Kuala Lumpur, Malaysia) and to assess the rate of correct diagnosis made by the referring primary care doctors. Clinical records of all 31 patients with CLM seen between January 2006 and June 2010 were retrieved. The majority of patients were male. The mean age was 32.2 years. Pruritus was reported in 83.9% of cases and serpiginous tracts in 100%. The mean lesion count was 4.4 and the mean duration of disease before presentation was 3.1 weeks. The majority of skin lesions were on the buttock and lower extremities. Only 45.2% of patients had the correct diagnosis made by the referring primary care doctors. Older age of patients and lower number of lesions were associated with a higher rate of correct diagnosis. The low rate of correct diagnosis made by the referring primary care doctors to the dermatologists in this study warrants the need for education of not only primary care doctors but also future primary care providers, consisting of medical students, house officers and junior medical officers.

Changes in complement C3 levels following treatment of patients with Brugia malayi infection

Yadav M

Southeast Asian J. Trop. Med. Public Health, 1989 Jun;20(2):183-7.

PMID: 2609207

Serum IgG levels and complement C3 levels were assayed on Day 0, 1, 3-4, 7 and 56-70 post-treatment with diethylcarbamizine citrate (DEC) in a series to 26 patients with Brugia malayi infection and 6 volunteers without infection. On treatment, the microfilariae were cleared from the blood within 24 hours. The eosinophils decreased dramatically on Day 1 post-treatment but increased rapidly by Day 4 to 7 and then dropped to normal levels in 45 days. The serum IgG mean levels decreased briefly following treatment with DEC but then returned to original levels. However, the complement C3 levels gradually increased over the 2 months period of study reaching statistical significance levels (p less than 0.01) in patients with initial high blood microfilariae. The observation suggests that Brugia malayi infection probably induces a high rate of synthesis of complement C3 and this process continued in the post-treatment phase. Since, DEC treatment did not cause a decrease in complement C3 with the elimination of blood microfilariae, it would appear that the complement C3 is consumed following antibody attachment to the microfilariae as they enter the blood circulation.

PMID: 16570721

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.

Anthelmintic resistance in sheep and goat farms on Peninsular Malaysia

Chandrawathani P, Adnan M, Waller PJ

Vet Parasitol, 1999 May;82(4):305-10.

PMID: 10384906

The faecal egg count reduction test (FECRT) was conducted on 39 sheep farms and 9 goat farms located in Peninsular Malaysia. The anthelmintic groups used in these tests were the benzimidazoles, levamisole, the benzimidazole/levamisole combination, macrocyclic lactones and closantel. Results indicated that the prevalence of resistance to the benzimidazole group was high, with approximately 50% of the sheep farms and 75% of the goat farms having resistant nematode parasite populations present. Resistance to levamisole, closantel and ivermectin was also detected. Differentiation of the infective larvae derived from faecal cultures indicated that by far the most predominant parasite species was Haemonchus contortus.

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.

PMID: 30477758 DOI: 10.1016/j.pt.2018.10.006

An elicitation exercise was conducted to collect and identify pressing questions concerning the study of helminths in livestock, to help guide research priorities. Questions were invited from the research community in an inclusive way. Of 385 questions submitted, 100 were chosen by online vote, with priority given to open questions in important areas that are specific enough to permit investigation within a focused project or programme of research. The final list of questions was divided into ten themes. We present the questions and set them briefly in the context of the current state of knowledge. Although subjective, the results provide a snapshot of current concerns and perceived priorities in the field of livestock helminthology, and we hope that they will stimulate ongoing or new research efforts.

Control of haemonchosis in Malaysian goats with closantel

Dorny P, Vercruysse J, Jalila A, Sani R, Symoens C

Vet Parasitol, 1994 Jun;53(3-4):233-41.

PMID: 7975118

The therapeutic and prophylactic effects of closantel on natural infections with Haemonchus contortus were studied in goats in Peninsular Malaysia. Closantel was highly effective against H. contortus, either at a subcutaneous (s.c.) injection of 5.0 mg kg-1 body weight (100%), or in an oral drench mixture with mebendazole at a dose of 10.0 mg kg-1 (99.2%), as indicated by faecal egg counts. H. contortus larvae were absent from faecal cultures for 5, 6 and 7 weeks following treatment with s.c. injections of closantel at doses of 2.5 mg kg-1, 5.0 mg kg-1 and 10.0 mg kg-1 respectively, and for 6 weeks after treatment with closantel at 10.0 mg kg-1, given orally. Through its sustained activity, closantel not only prevented reinfection with H. contortus but also caused a dramatic reduction in pasture contamination. The potential utility of closantel in the strategic control of haemonchosis in goats, and as an alternative treatment for benzimidazoles and levamisole resistant H. contortus strains, is discussed.

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

PLoS Negl Trop Dis, 2013;7(8):e2377.

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.

Anthelmintic resistance in Haemonchus contortus from sheep in Malaysia

Pandey VS, Sivaraj S

Vet Parasitol, 1994 May;53(1-2):67-74.

PMID: 8091619

Albendazole, oxfendazole, fenbendazole, levamisole, closantel, ivermectin and febantel were administered to sheep on four farms and their efficacy assessed by faecal egg count reduction test. High level of resistance of Haemonchus contortus was found to benzimidazoles (albendazole, oxfendazole, fenbendazole) on all farms and to febantel on the one farm where it was tested. No resistance to closantel and levamisole was observed. Resistance to ivermectin was absent on the three farms examined under this study, but has been reported on the fourth farm in earlier work. It is concluded that anthelmintic resistance to benzimidazoles and the probenzimidazole, febantel, is a serious and widespread problem in H. contortus in sheep in Malaysia.
