  1. Intestinal helminths in relation to eosinophilic lung (tropical eosinophilia) in Singapore
    Schacher JF, Danaraj TJ
    Am J Trop Med Hyg, 1960 Nov;9(6):616-9.
    PMID: 13747131
    The above survey based on a study of single stool specimens from 569 patients, drawn from a hospital population belonging to different ethnic groups and having different cultural backgrounds, failed to indicate an association between intestinal helminth infection and eosinophilic lung. The higher prevalence of eosinophilic lung in Indians than in the other ethnic groups, as reported previously, cannot be explained on a basis of differences in the prevalence of the intestinal helminths, Ascaris lumbricoides, hookworm, Trichuris trichiura and Strongyloides stercoralis.

    PMID: 5938434
    Saline extracts of ether-treated Dirofilaria immitis, Ascaris suum, and Ancylostoma spp. were used in indirect hemagglutination tests of serum from 164 patients with a diagnosis of eosinophilic lung and 114 persons with other diseases or no disease (blood donors). In the first group, positive reactions with one, two or all three antigens were obtained in 89 percent of cases and the titers, at medium or high levels in 77 percent, decreased after treatment with diethylcarbamazine. In the other group, antibodies were demonstrable in the serum of only 22 percent of cases and titers usually were low. These observations indicate the presence of several antigen-antibody systems, some of which appear to be specific. With extracts of Dirofilaria the indirect hemagglutination and the complement-fixation tests were similar in sensitivity and specificity, but the results from neither test appeared to indicate infection with a specific worm.

  4. Eosinophilic meningitis beyond the Pacific Basin: the global dispersal of a peridomestic zoonosis caused by Angiostrongylus cantonensis, the nematode lungworm of rats

    The principal etiologic agent of human eosinophilic meningitis, Angiostrongylus cantonensis, was first detected in rats in Canton, China in 1933. The first human case was detected on Taiwan in 1944. Epidemic outbreaks were noted on Ponape (E. Caroline Is.) from 1944 to 1948. The disease may present as transient meningitis or a more severe disease involving the brain, spinal cord and nerve roots, with a characteristic eosinophilia of the peripheral blood and CSF. Since 1961 it has been known that human infections are usually acquired by purposeful or accidental ingestion of infective larvae in terrestrial mollusks, planaria and fresh-water crustacea. There is no effective specific treatment. The African land snail, Achatina fulica played an important role in the panpacific dispersal of the organism: it will be important in Africa in the future as well. Rats were, and will continue to be the principal agents of expansion of the parasite beyond the Indopacific area. During and just after WWII the parasite was introduced, and/or spread passively from South and Southeast Asia into the Western Pacific islands and eastward and southward through Micronesia, Melanesia, Australia and into Polynesia, sequestered in shipments of war material and facilitated by post-war commerce. In the 1950s numerous cases were identified for the first time on Sumatra, the Philippines, Taiwan, Saipan, New Caledonia, and as far east as Rarotonga and Tahiti. Then cases were detected in Vietnam, Thailand, Cambodia, Java, Sarawak, the New Hebrides, Guam and Hawaii during the 1960s. Subsequently in the Pacific Basin the disease has appeared on Okinawa, other Ryukyu islands, Honshu, Kyushu, New Britain, American Samoa and Western Samoa, Australia, Hong Kong, Bombay, India, Fiji and most recently in mainland China. The parasite in rats now occurs throughout the Indopacific Basin and littoral. Beyond the Indopacific region, the worm has been found in rodents in Madagascar (ca 1963), Cuba (1973), Egypt (1977), Puerto Rico (1984), New Orleans, Louisiana (1985) and Port Harcourt, Nigeria (1989). Human infections have now been detected in Cuba (1973), Réunion Island (1974) and Côte d'Ivoire (1979) and should be anticipated wherever infected rats of mollusks have been introduced. Caged primates became infected in zoos in Hong Kong (1978) and New Orleans and Nassau, Bahamas (1987). The use of mollusks and crustacea as famine foods, favored delicacies and medicines has resulted in numerous outbreaks and isolated infections. Economic and political instability, illicit trade, unsanitary peridomestic conditions and lack of health education promote the local occurrence and insidious global expansion of parasitic eosinophilic meningitis.(ABSTRACT TRUNCATED AT 400 WORDS)

    Zainudin BM, Ismail O
    Singapore Med J, 1990 Dec;31(6):629-31.
    PMID: 2281365
    A 44-year-old Indian housewife presented with prolonged cough, intermittent fever, loss of weight and shortness of breath on exertion. Physical examination revealed a thin lady with fine crackles on both lungs. Marked eosinophilia and elevated erythrocyte sedimentation rate were noted on peripheral blood. Chest radiograph showed characteristic bilateral infiltrates affecting the periphery of both lungs. Treatment with corticosteroid resulted in dramatic improvement in symptoms, signs and radiographic changes within a few days.

    PMID: 9432400
    The term 'tropical' refers to the region of the Earth lying between the Tropic of Cancer and the Tropic of Capricorn. Located between these equatorial parallels demarcating the Torrid Zone are several underdeveloped and developing countries: Thailand, the Philippines, Malaysia, Singapore, Indonesia, southern India, Sri Lanka, Brazil, Cuba, Ethiopia, Sudan and Nigeria, to name but a few considered to be 'tropical'. The climate in most of these countries is characterized by high temperatures and high humidity. The tropical climate and general state of socio-economic underdevelopment in such countries provide an ideal environment for pathogenic organisms, their vectors and intermediate hosts to flourish. Furthermore, the cultural habits and educational background of the people living in such countries expose them to pathogens and, when these people become infected, they readily become reservoirs for, or carriers of, those organisms. Ultimately, the adverse socioeconomic conditions of underdeveloped countries impede attempts to eradicate or control tropical diseases.

    Postgrad Med J, 1989 Nov;65(769):843-4.
    PMID: 2616421
    A 72 year old man developed acute organic brain syndrome associated with marked eosinophilia following self medication with a variety of drugs. Investigations revealed no other known causes of eosinophilia. Withdrawal of drugs resulted in dramatic drop in eosinophil count paralleled by clinical resolution of neurological problems. To our knowledge drug-induced eosinophilia has not previously been associated with acute organic brain syndrome.

  10. Kinetics of IgA and eosinophils following a low-dose, predominantly Haemonchus contortus infection of Boer goats
    Hayyan BN, Sharma RSK, Raimy N, Nisha M, Hussain K, Busin VM, et al.
    Parasite Immunol., 2020 06;42(6):e12707.
    PMID: 32118305 DOI: 10.1111/pim.12707
    AIMS: Most breeds of goat are more susceptible to nematode infection than sheep, and this appears to be a consequence of less effective immune responses. Several papers have considered the effectiveness of eosinophils and immunoglobulin A (IgA) in goats but differences in the induction of responses have not been studied in the same detail. The aim of this study was to look at the induction of eosinophil and IgA responses in Boer goats reared indoors under intensive conditions.

    METHODS AND RESULTS: The goats were experimentally infected with a low dose of 2400 Haemonchus contortus, Trichostrongylus spp. and Oesophagostomum spp. at a 6:1:1 ratio. Faecal egg counts (FEC), packed cell volume (PCV), IgA activity against third-stage larvae and peripheral eosinophilia were measured twice a week for eight weeks. The infection generated an IgA response but did not significantly increase peripheral eosinophilia in the 25 infected kids compared with the 4 control animals. FEC was not associated with IgA activity or eosinophilia.

    CONCLUSION: A detailed analysis of IgA and eosinophil responses to deliberate nematode infection in Boer goats showed that there was an increase in nematode-specific IgA activity but no detectable eosinophil response. In addition, there was no association between increased IgA activity or eosinophilia with egg counts and worm burdens. These suggest that IgA and eosinophils do not act to control nematode infection in goats.

  11. Fulltext Correlation between Soil Transmitted Helminth Infection and Eosinophil Levels among Primary School Children in Medan
    Darlan DM, Tala ZZ, Amanta C, Warli SM, Arrasyid NK
    Open Access Maced J Med Sci, 2017 Apr 15;5(2):142-146.
    PMID: 28507618 DOI: 10.3889/oamjms.2017.014
    BACKGROUND: Soil Transmitted Helminth infection is one of most prevalent health problems worldwide, especially in environments with poor sanitation. Based on World Health Organisation (WHO) data, more than 2 billion people, or 24% of the world's population, are infected with intestinal parasite. The highest prevalence is located in areas of poor sanitation and unsafe water supplies. In Indonesia, the prevalence of parasite infections is 15% of the entire population.

    AIM: The purpose of this study was to determine the relationship between Soil Transmitted Helminth infection on levels of eosinophils among primary school children. In addition, this study also aimed to determine the prevalence of different types of worm infections and the levels of eosinophils in children infected with worms.

    MATERIAL AND METHODS: This study was analytic observational using a cross-sectional method. The sampling technique was consecutive and in total 132 samples was obtained. The study involved primary school children in Amplas Medan and Hamparan Perak, Deli Serdang through May to October 2016. Univariate analysis was performed to determine STH infection prevalence and bivariate analysis was used to find the correlation between STH infection and eosinophil levels through a Chi square (χ2) test.

    RESULTS: The results showed that the prevalence of Soil Transmitted Helminth was 7.6%. The most common types of STH infection were 3.8% with Trichuris trichiura and 3% with Ascaris lumbricoides. A significant correlation was found between Parasite infection and eosinophil levels (Contingency Coefficient (C) = 0.2, χ2 = 5.3, p = 0.021) and the risk of STH infection that caused eosinophilia or increased eosinophil levels in the children with a Prevalence Ratio (PR) of 1.56 (Confidence Interval (CI) 95%: 1.10-2.22).

    CONCLUSION: It is recommended that schools at similar risk improve and maintain hygiene and healthy behaviour in the school environment and that parents and teachers pay greater attention to the cleanliness of their children.

    Eosinophilic granulomatosis with polyangiitis (formerly known as Churg-Strauss syndrome) is a rare vasculitis in children. It commonly presents with respiratory symptoms, especially asthma, allergic rhinitis, and peripheral eosinophilia. Involvement of other systems, such as renal and cardiac, may carry a poor prognosis. Anti-neutrophil cytoplasmic antibodies have been found less frequently in children with this condition. We report a case of a 15-year-old male who presented with indurated and pruritic papules on both legs and peripheral eosinophilia without other system involvement. Histopathological findings from a skin biopsy were suggestive of eosinophilic granulomatosis with polyangiitis. Anti-neutrophil cytoplasmic antibodies were negative.

    Thrombocytosis in children as well as in adult is defined as platelet count ≥ 450 × 109/L, and it is usually a reactive feature to various medical disorders. However, extreme thrombocytosis (platelet count ≥ 1000 × 109/L) is an uncommon finding among pediatric and adult patients, which may indicate more than a reactive phenomenon. We describe a case of a five-year-old boy who was admitted due to recurrent epistaxis. He had no history of allergic tendency or trauma. Physical examination was unremarkable except for shotty neck nodes. Laboratory results at presentation showed normal hemoglobin and total leukocyte count with eosinophilia (0.92 × 109/L), and extreme thrombocytosis. Other relevant investigations including coagulation profile, serum ferritin, liver, and renal function tests were all within normal ranges. Stool samples for ova and cysts were negative. The peripheral blood smear and bone marrow aspirate confirmed thrombocytosis with increased megakaryocytic proliferation and no artefactual reasons for the high platelets such as red blood cell fragments. Different causes of thrombocytosis in childhood were investigated after considering the possible differential diagnoses for extreme thrombocytosis.

    Epilepsy is a common neurological disorder affecting approximately 50 million people worldwide. Antiepileptic drugs (AEDs) are commonly used to treat the disease depending, mainlyon the type of seizure. However, the useof AEDs mayalso lead to cutaneous adverse drug reactions (cADR) such as toxic epidermal necrolysis (TEN), Stevens-Johnsonsyndrome (SJS), exfoliative dermatitis (ED) and drug‐induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms (DIHS/DRESS), which are unwanted comorbidities in epilepsy. It was first discoveredthat the HLA-B*15:02 allele was strongly associatedwith carbamazepine(CBZ)-induced SJS/TEN amongHan Chinese and this ledto the discovery of other HLAallelesand cytochrome P450 (CYP) genes that were significantly associatedwith various AED-inducedcADRsacross variouspopulations. This mini-reviewis an update on the latest findings ofthe involvement of various HLA alleles and CYP alleles in cADRs caused by CBZ, phenytoin (PHT), oxcarbazepine (OXC) and lamotrigine(LTG) in different case-control studies around the world. From our review, we found that CBZ-and PHT-induced cADRsweremore commonly reportedthan the other AEDs.Therefore,there were morerobust pharmacogenetics studies related to these AEDs. OXC-and LTG-induced cADRswereless commonly reported,and somore studies are needed to validate the reported association of the newer reported HLA alleles with theseAEDs. It is also importantto considerthe allelic frequency within a given population before concludingthe use of thesealleles as genetic markers to prevent AED-induced cADR. Overall, the current body of research pointto a combination of alleles as a better pharmacogenetic marker comparedto the use of a single gene as a genetic marker for AED-induced cADR.

    MyJurnal
    Kimura’s disease (KD) is a rare, benign chronic inflammatory disease of unknown aetiology, typically presents in the Orientals as subcutaneous masses in the head and neck region that could be easily misdiagnosed as a malignant tumour, leading to unnecessary radical surgery or intensive cytotoxic therapy. It has been mainly reported in the Chinese and Japanese literature. It is difficult to diagnose before tissue biopsy and fine needle aspiration cytology (FNAC) has limited value. Hence, unless the pathologists are aware of this entity, it might be mistaken as a malignant lesion. We encountered a case of KD in a Malay patient presenting as a parotid mass that was initially diagnosed as Hodgkin’s lymphoma (HL). This disorder should be suspected in young male Asian patients presenting with a painless unilateral mass in the head and neck region with associated hypereosinophilia.

    We would like to highlight an unusual clinical presentation of Kimura's disease, a rare, benign, idiopathic condition, usually seen as swelling and lesions of the head and neck region and commonly affecting young men of Asian descent. It is rare for this disorder to present with lesions on other parts of the body, especially the lower limbs. We report a 27-year-old man who presented with a large mass located at the inguinal region and extending down to the upper thigh. Due to the large size of the mass (28 x 18 cm), our provisional diagnosis was a soft tissue sarcoma. Open biopsy showed that the lesion was benign.

    Kimura disease presents as benign lesion and is commonly present among the Asian population. It is a disease with a favourable prognosis and a peak age of onset in the third decade. It is a chronic inflammatory disorder of unknown etiology that involves the lymph nodes and subcutaneous tissues of the head and neck region. We report a case of a 15-year-old boy with multiple Kimura lymphadenopathies involving the left posterior auricular region as well as the anterior and posterior triangles of the neck.

    MyJurnal
    This article highlights the case of a 44-year old Malay man who is diagnosed as having treatment resistant schizophrenia on Clozapine, which then developed Polycythemia Rubra Vera (PRV). It is known that a major side effect for Clozapine is of agranulocytosis, that is a potentially fatal side effect. However, there have been reported disturbances of other hematological parameters, which result in other abnormalities including leucopenia, leucocytosis, thrombocytopenia, thrombocytosis and eosinophilia. Could this case be a pure medical condition of PRV or is there a relation to the effects of Clozapine? In this paper, the aim is to report a case of blood dyscrasia in a 44-year old male who developed Polycythemia Rubra Vera a year after he was observed to have abnormal full blood count results.

    Introduction: Ascariasis is a parasitic infection, which commonly affects immunocompromised patients. Most pa-tients remained asymptomatic during the early larval migration stage and respond well with conventional anti-hel-minthic drugs. Previous literature had reported symptomatic Ascaris infection mimicking bacterial pneumonia and the typical eosinophilia found in Loeffler syndrome was absent in patients on corticosteroids. Thus, a high index of suspicion for ascariasis is needed for immunosuppressed patients presented with infection. We present here a case of severe ascariasis infection in a systemic lupus erythematosus patient. Case description: A 16-year-old boy presented with fever, generalized maculopapular rash associated with neutropenia and thrombocytopenia. He was treated initially as Dengue Fever initially. However his symptoms did not resolve at even day 14 of admission. On further assessment, we were convinced he has SLE based upon presence of malar rash, oral ulcers, urinary protein-uria, persistent leucopenia, thrombocytopenia with low complements and ANA positive. He was promptly started on IV hydrocortisone. He showed a good progress in the first few days. On day 5 of admission, he coughed out a round worm which later identified as Ascarisis lumbricoides. He was started on Albendazole. Unfortunately he developed hemoptysis and respiratory compromisation where he required intubation. Post intubation he went into cardiac arrest, which required CPR. Following that event, his condition further deteriorated with multi organ failure. He succumbed to his illness three days later. Conclusion: Immunocompromised patients are prone to opportunistic infections including parasitic infections. we present here a case of ascariasis in an SLE patient who unfortunately succumbed to the illness. Due to the variable clinical symptoms that mimic other infections, screening for parasitic infections needs to be considered especially if the patients do not respond to antibiotics and routine treatments.

    Introduction: Strongyloidiasis is endemic in the tropical and subtropical regions. Clinical manifestations of the dis-ease can range from asymptomatic eosinophilia in an immunocompetent host to a wide range of presentations in immunocompromised patients. Failure to consider the diagnosis of strongyloides infection, especially Strongyloides hyperinfection syndrome, is a major contributor of high mortality rate in such cases. Case Description: We report a case of 60 years old gentleman who was admitted to Sarawak General Hospital for a left subtrochanteric femur pathological fracture and the diagnosis of multiple myeloma was made in the same setting. He was started on treat-ment for multiple myeloma which includes high dose steroids. During his course of admission, he was diagnosed with hospital-acquired pneumonia was subsequently initiated with broad-spectrum antibiotics. Despite being exten-sively treated with multiple courses of broad-spectrum antibiotics, he deteriorated clinically, with eventual respirato-ry failure requiring ventilator support and ICU admission. A diagnosis of strongyloides hyperinfection syndrome was made after an incidental discovery of larvae in his sputum, which was later confirmed with stool sample. He was given a one-week course of albendazole 400mg twice daily and clinical improvement was observed. A repeated stool sample also demonstrated clearance of the parasites. Conclusion: This case highlights the need for clinical sus-picion of strongyloides hyperinfection syndrome in cases of unresolved pneumonia, especially for patients with risk factors of underlying immune-deficiency state. Preventive steps such early detection and eradication of strongyloides infection should be undertaken prior to initiation of immuno-suppressive therapy.
