Abstract
: We herein describe a case of Wuchereria bancrofti infection in a previously healthy 37-year-old Nepalese man. The patient presented with a history of milky urine with subsequent acute urinary retention lasting for a few days. The presence of microfilariae was confirmed on both peripheral blood and urine smears obtained at midnight. He was conservatively treated with diethylcarbamazine combined with doxycycline. Filariasis was previously endemic in southern parts of Japan, although it has been eradicated. Clinicians should remember filariasis as a potential etiology of urinary retention, especially in cases that may be associated with imported infectious disease.

A 38-year-old man presented with a history of passage of milky urine for the past 6 months; he had lost weight but denied dysuria and fever. Physical examination showed a thin, malnourished man weighing 52 kg and no lymphadenopathy but mild bipedal pitting edema. Urine sample showed milky-appearing urine (Figure 1A). Urinalysis showed urinary triglycerides of 167 mg/dL against serum of 84 mg/dL, and 24-hour urinary proteins were 6.5 g. Centrifuged urine revealed sheathed microfilaria having a un...

Human population migration is a common phenomenon in developing countries. Four categories of migration—endemic to nonendemic areas, rural to urban areas, non-MDA areas to areas that achieved lymphatic filariasis (LF) control/elimination, and across borders—are relevant to LF elimination efforts. In many situations, migrants from endemic areas may not be able to establish active transmission foci and cause infection in local people in known nonendemic areas or countries. Urban areas are at risk ...

Some alphaviruses and flaviviruses, such as the transfusion-relevant Chikungunya and West-Nile virus, are transmitted by mosquitoes. Such viruses are called arboviruses. Bacteria typically transmitted by ticks include Coxiella burnetii [1], Borrelia, Ehrlichia, and Anaplasma. These are referred to as arbobacteria [2]. Protozoae include plasmodia which are transmitted via mosquitoes, leishmania transmitted via sand flies (Phlebotomus), and for example trypanosoma transmitted via kissing bugs (Tri...

Globally, 40 million people live with the chronic effects of lymphatic filariasis (LF), making it the second leading cause of disability in the world. Despite this, there is limited research into the experiences of people living with the disease. This review summarises the research on the experiences of people living with LF disability. The review highlights the widespread social stigma and oppressive psychological issues that face most people living with LF-related disability. Physical manifest...

Filariasis is a global health problem commonly seen in tropics and subtropics. Microfilariae has been reported in cytological specimens from various sites but is an unusual finding from sediments of centrifuged normally voided urine samples. This highlights the presence of adult worms in the lymphatics and thus helping in prompt decision to start antihelminthic treatment besides providing surgical treatment for chyluria. Diagn.

Japan is said to have eradicated filariasis some 25 years ago, but the exact time (and even the definition of eradication) is not clear. However, the results of successful control programs clearly indicate that the number of microfilaria carriers had been reduced to a very low level long before the “eradication”. As filariasis disappeared, the once stigmatized disease quickly lost clinical significance. At the same time, the number of parasitologists and researchers interested in filariasis dwin...

We present filaria-nested polymerase chain reaction (PCR), which is based on amplification of first internal transcribed spacer rDNA to distinguish three parasitic filarial species (Onchocerca volvulus, Mansonella ozzardi and Mansonella perstans) that can be found in the Amazon Region. Nested PCR-based identifications yielded the same results as those utilizing morphological characters. Nested PCR is highly sensitive and specific and it detects low-level infections in both humans and vectors. No...

Besides peripheral blood smears, microfilariae have been described in aspirate smears from different sites. Identification of microfilariae in the chylous urine of otherwise asymptomatic filarial patients has been rarely described. One such case is presented.

The ambitious and exciting Global Programme to Eliminate Lymphatic Filariasis (GPELF) is largely based on a strategy of mass drug administration (MDA) of repeated rounds of antifilarial medications to endemic populations around the world. Diagnostic tools are important to GPELF because they affect decisions regarding where to distribute MDA, how to measure its effects, how to define targets and endpoints for stopping MDA, and how to monitor populations for possible resurgence of filariasis trans...

Summary Objective To assess the impact of hydrocele and lymphoedema on the quantity and quality of productive work of weavers. Method Case–control study in an endemic village in Andhra Pradesh, India. We collected qualitative data on work activities from cases and age- and sex-matched controls through informal discussions and observation. Results The mean (±standard deviation) daily work time of cases was 7.38 h (±2.47), significantly less than that of controls (8.17 ± 2.41 h). Lost work time wa...

Lymphatic filariasis is a major public health problem in the developing countries. In India, around 90% of the cases are attributed to Wuchereria bancrofti species morphologically identified as sheathed parasites with tail tip free of nuclei. Microfilariae have been described in urine specimens from patients with chylous and achylous hematuria as well as in a spectrum of other body fluids. Case reports describe their presence in aspirates from numerous neoplasms. However, their association with ...

Although Sierra Leone lies within the worldwide filarial belt, chyluria (the passage of milky coloured urine) is a rare presenting symptom in clinical practice. This report describes a confirmed case of parasitic filariasis presenting in a 72-year-old woman. After treatment with a combination of ivermectin and albendazole, her symptoms resolved within 48 h and she was symptom free at 6 months.

Background The current treatment therapies for chyluria are often invasive and recurrent. Here, we investigated a novel noninvasive treatment of chyluria with high-intensity focused ultrasound (HIFU) and evaluated its clinical efficacy.

Abstract Human filariae are vector-borne parasites and the causative agents of various diseases, including human onchocerciasis and lymphatic filariasis. Onchocerciasis causes a spectrum of cutaneous and ophthalmologic manifestations (including blindness) and has long been a major public health problem in Bioko Island (Equatorial Guinea). Bioko Island has been included in the WHO's Onchocerciasis Control Program since 1987. In Bioko Island, the specificity and sensitivity of clinical Onchocerca ...

Chyluria, commonly seen in south Asian countries, is mainly a manifestation of lymphatic filariasis as a result of infestation with Wuchereria bancrofti, although many other causes can contribute. Many patients can be effectively treated with dietary modifications and drug therapy. The most widely used drug is diethyl carbamazine. The recurrences are common after such treatment. Such patients would benefit from sclerotherapy to obliterate the lympatico-renal fistulae located mainly in the renal ...

repeated examinations for microfilaremia at midnight did not detect the parasite at all. Medical therapy was initiated with dietary restriction and oral administration of ezetimibe; however, the treatment did not improve the symptoms. Subsequently, a combination of DEC and doxycycline was administered, then, chyluria promptly and successfully disappeared. Wuchereria bancrofti has been gradually eradicated, and physicians in developed countries are not familiar with filariasis [2]. The parasitosi...
