Treatment of refractory paediatric giardiasis using secnidazole plus albendazole: a case series.

Giardia lamblia, the aetiological agent of human giardiasis, is a frequently identified protozoan infection of the upper small intestine. It mainly affects children and has a wide range of clinical manifestations, from asymptomatic carriage to acute or chronic diarrhoea with dehydration, abdominal pain, nausea, vomiting, excessive flatulence and weight loss. Standard treatment for giardiasis is commonly with 5-nitroimidazole (5-NI) compounds, or nitazoxanide; however, some individuals experience treatment failure.

Efficacy of mebendazole in paediatric patients with giardiasis: A systematic review and meta-analysis.

Mebendazole (MBZ), a benzimidazole compound, has received attention in treating patients with giardiasis because it has shown beneficial effects both in vitro and in vivo. The aim of this study was to assess with a systematic review and meta-analysis of randomized controlled trials (RCTs) the efficacy of MBZ compared to other antigiardial agents in children. We searched RCTs of MBZ for the treatment of Giardia infections published in PubMed and EBSCOhost.

Potential sexual transmission of Giardia in an endemic region: a case series.

We present four cases in which probable sexual transmission of Giardia lamblia was suspected. Diagnosing this mode of transmission in endemic areas is often difficult and should be considered only as possible, because exposure to poor sanitation and a potentially contaminated environment are always latent. However, as patients reported, there was no history of drinking tap water, exposure to recreational water, eating contaminated food, or other potential sources of infection but anilingus with an infected partner.

Giardiasis: a diagnosis that should be considered regardless of the setting.

Although Giardia, the aetiological agent of giardiasis, is one of the most prevalent intestinal parasitic infections world-wide, for industrialised countries, it is mainly appreciated as an imported disease with the minimal local transmission. However, the current evidence challenges this perception; Giardia has relevance beyond the high prevalence areas. This infection may be asymptomatic or cause gastrointestinal complains and long-term sequelae, including irritable bowel syndrome, chronic fatigue and impaired child growth and cognitive development.

Combination therapy in the management of giardiasis: What laboratory and clinical studies tell us, so far.

Treatment failures in patients suffering from giardiasis are not uncommon feature. The most frequent approach in these cases is to treat these patients with longer repeated courses and/or higher doses of the primary therapy, or using drugs from a different class to avoid potential cross-resistance. However, a higher rate of adverse events may limit this strategy.

A meta-analysis of the efficacy of albendazole compared with tinidazole as treatments for Giardia infections in children.

Metronidazole is frequently used against Giardia infection; however, it has been associated with significant failure rates in clearing parasites from the gut; additionally, as it should be taken for 5 to 10 days, it is associated with poor compliance, probably due to side effects. Other drugs, including tinidazole (TNZ) and albendazole (ABZ) have been included in the antigiardial armamentarium. Our aim was to assess the efficacy of ABZ compared with TNZ in Giardia infections in children.

Chloroquine: An Old Drug with New Perspective Against Giardiasis.

The occurrence of treatment failures to first-line treatment for giardiasis, one of the most widespread although neglected parasitic disease, has long been recognised. Nowadays, it starts to represent a great challenge to clinicians, especially in endemic countries. This requires the introduction of new drug interventions, but the development of novel drugs is a time and money consuming effort with most of the compounds never reaching the market.

A bibliometric study of international scientific productivity in giardiasis covering the period 1971-2010.

Introduction: Despite years of relative neglect, interest in Giardia infection seems to be recently growing, perhaps in part due to its inclusion into the World Health Organization's Neglected Diseases Initiative since 2004. The purpose of this study was to provide an overview of Giardia and giardiasis research over time, as represented by the quantity of published papers.

Methodology: Data for this study were collected from the electronic PubMed/Medline database of National Library of Medicine's (NLM), due to it is easily accessibility and wide use.

Care-seeking behaviour and diagnostic processes for symptomatic giardiasis in children attending an academic paediatric hospital.

Giardiasis is one of the commonest intestinal parasitic infections in Cuba. In order to determine care-seeking behaviour and diagnostic processes in paediatric in-patients with giardiasis, structured questionnaires were administered by interview mothers of children with giardiasis during January to December 2010. During the study period, 97 children were diagnosed with giardiasis, of whom 86 (88·6%) caregivers were interviewed.

Potential impact of macroclimatic variability on the epidemiology of giardiasis in three provinces of Cuba, 2010-2012.

Climate change and variability are common phenomena affecting various infectious diseases. Many studies have been performed on vector-borne diseases; however, few studies have addressed such influences on intestinal parasitic diseases (e.g.

Management of chronic Giardia infection.

Advances in our understanding of chronic giardiasis (CG) may improve our care of patients in this stage of the disease. This review proposes a new concept of CG and highlights the recent advances in our understanding and management of this condition. According to this review, management requires, initially, an accurate diagnosis, which may exclude several conditions that can mimic CG.

[Clinical features of giardiasis in different age groups of pediatric in-patients].

Introduction: It has been suggested that the clinical features of giardiasis might vary in patients of different age groups.

Objective: To compare clinical presentation of giardiasis in children less than 5 years of age and older children.

Methods: A retrospective study of patients hospitalized with giardiasis during 2007 was performed.

Abdominal pain and asthenia as common clinical features in hospitalized children for giardiasis.

Giardiasis is a disease with worldwide distribution, although its prevalence differs from country to country. In order to investigate the clinical pattern of giardiasis in in-patient children, a case-control study was carried out. In-patient children who had Giardia lamblia infection were compared with non Giardia-infected children, focusing only on 4 clinical manifestations: diarrhoea, abdominal pain, asthenia and vomiting.

Parental perceptions of giardiasis: a study in an outpatient paediatric hospital setting in havana, cuba.

Background. Giardia lamblia is an important cause of diarrhoeal disease throughout the world. Giardiasis- a mild and self-limiting disease that this protozoan causes- is perceived as a harmful disease.

Mebendazole compared with secnidazole in the treatment of adult giardiasis: a randomised, no-inferiority, open clinical trial.

To compare the efficacy and safety of mebendazole and secnidazole in the treatment of giardiasis in adult patients, a single-centre, parallel group, open-label, randomized non-inferiority trial was carried out. One-hundred and 26 participants who had symptomatic Giardia mono-infection took part in the study. Direct wet mount and/or Ritchie concentration techniques and physical examinations were conducted at the time of enrolment and at the follow-up visit.

Caregiver perspectives for the prevention, diagnosis and treatment of childhood giardiasis in Havana City, Cuba. A qualitative study.

Although long considered a non-pathogenic protozoan, Giardia lamblia is now a well recognized cause of abdominal discomfort, diarrhoea and failure-to-thrive in children. The overall prevalence of this infection in Cuban population is about 7.2%; however, higher prevalences have been found among young children attending day-care centres and primary school in the country.

Giardiasis: the ever-present threat of a neglected disease.

Although giardiasis has been a threat to mankind for thousands of years, this protozoan infection was, until recently, relatively neglected. Giardia duodenalis is recognised as a major cause of parasite-induced diarrhoea in humans and animals, and is currently an important public health problem, placing a heavy burden on both diagnostic and treatment services at health care institutions, mostly in developing countries, but also in highly developed countries. Steady progress in recent years, using a combination of molecular, immunological, and clinical approaches, has substantially increased our understanding of Giardia and important aspects of the clinical manifestations that it causes.
