Ivermectin versus albendazole or thiabendazole for Strongyloides stercoralis infection

Background: Strongyloidiasis is a gut infection with Strongyloides stercoralis which is common world wide. Chronic infection usually causes a skin rash, vomiting, diarrhoea or constipation, and respiratory problems, and it can be fatal in people with immune deficiency. It may be treated with ivermectin or albendazole or thiabendazole. Objectives: To assess the effects of ivermectin versus benzimidazoles (albendazole and thiabendazole) for treating chronic strongyloides infection. Search methods: We searched the Cochrane Infectious Diseases Group Specialized Register (24 August 2015); the Cochrane Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library; MEDLINE (January 1966 to August 2015); EMBASE (January 1980 to August 2015); LILACS (August 2015); and reference lists of articles. We also searched the metaRegister of Controlled Trials (mRCT) using ‘strongyloid*’ as a search term, reference lists, and conference abstracts. Selection criteria: Randomized controlled trials of ivermectin versus albendazole or thiabendazole for treating chronic strongyloides infection. Data collection and analysis: Two review authors independently extracted data and assessed risk of bias in the included trials. We used risk ratios (RRs) with 95% confidence intervals (CIs) and fixed- or random-effects models. We pooled adverse event data if the trials were sufficiently similar in their adverse event definitions. Main results: We included seven trials, enrolling 1147 participants, conducted between 1994 and 2011 in different locations (Africa, Southeast Asia, America and Europe). In trials comparing ivermectin with albendazole, parasitological cure was higher with ivermectin (RR 1.79, 95% CI 1.55 to 2.08; 478 participants, four trials, moderate quality evidence). There were no statistically significant differences in adverse events (RR 0.80, 95% CI 0.59 to 1.09; 518 participants, four trials, low quality evidence). In trials comparing ivermectin with thiabendazole, there was little or no difference in parasitological cure (RR 1.07, 95% CI 0.96 to 1.20; 467 participants, three trials, low quality evidence). However, adverse events were less common with ivermectin (RR 0.31, 95% CI 0.20 to 0.50; 507 participants; three trials, moderate quality evidence). In trials comparing different dosages of ivermectin, taking a second dose of 200 mug/kg of ivermectin was not associated with higher cure in a small subgroup of participants (RR 1.02, 95% CI 0.94 to 1.11; 94 participants, two trials). Dizziness, nausea, and disorientation were commonly reported in all drug groups. There were no reports of serious adverse events or death. Authors’ conclusions: Ivermectin results in more people cured than albendazole, and is at least as well tolerated. In trials of ivermectin with thiabendazole, parasitological cure is similar but there are more adverse events with thiabendazole.

Are alternative strategies required to accelerate the global elimination of lymphatic filariasis? Insights from mathematical models

Background. With the 2020 target year for elimination of lymphatic filariasis (LF) approaching, there is an urgent need to assess how long mass drug administration (MDA) programs with annual ivermectin + albendazole (IA) or diethylcarbamazine + albendazole (DA) would still have to be continued, and how elimination can be accelerated. We addressed this using mathematical modeling. Methods. We used 3 structurally different mathematical models for LF transmission (EPIFIL, LYMFASIM, TRANSFIL) to simulate trends in microfilariae (mf) prevalence for a range of endemic settings, both for the current annual MDA strategy and alternative strategies, assessing the required duration to bring mf prevalence below the critical threshold of 1%. Results. Three annual MDA rounds with IA or DA and good coverage (?65%) are sufficient to reach the threshold in settings that are currently at mf prevalence <4%, but the required duration increases with increasing mf prevalence. Switching to biannual MDA or employing triple-drug therapy (ivermectin, diethylcarbamazine, and albendazole [IDA]) could reduce program duration by about one-third. Optimization of coverage reduces the time to elimination and is particularly important for settings with a history of poorly implemented MDA (low coverage, high systematic noncompliance). Conclusions. Modeling suggests that, in several settings, current annual MDA strategies will be insufficient to achieve the 2020 LF elimination targets, and programs could consider policy adjustment to accelerate, guided by recent monitoring and evaluation data. Biannual treatment and IDA hold promise in reducing program duration, provided that coverage is good, but their efficacy remains to be confirmed by more extensive field studies.

Cystic microfilarial infestation of the liver: A rare presentation

Cystic liver lesions in an adult may occur for a variety of reasons, most of which are benign in nature. Infiltrating benign lesions in the liver parenchyma may pose a clinical challenge in diagnosis and management. In the case presented herein, a cystic lesion adjacent to the gall bladder and involving the liver parenchyma had to be differentiated from gall bladder carcinoma, which is quite common in India. Parasitic infestation of the liver is an extremely rare presentation and may pose a significant challenge in its diagnosis and management. This case highlights an infrequent presentation and the challenges in the clinical approach and subsequent management.

Formulation, physical characterization and in vitro evaluation of medicated chewing gum: Diethylcarbamazine citrate

Truncate Infections close by helminthes, or parasitic worms, affect more than two billion people worldwide. Looking at this situation an attempt has been made to formulate a novel drug delivery system known as medicated chewing gum containing masticatory gum base with pharmacologically active ingredient diethylcarbamazine citrate (used as a first-line agent for control and treatment of Lymphatic filariasis and for therapy of tropical pulmonary eosinophilia caused by Wuchereria bancrofti and Brugia malayi). Optimized formulations of medicated chewing gum with varying concentration of gum base were formulated. Evaluation parameter like Texture analysis (Hardness, Firmness and Springiness test) is carried out by Texture analyzer apparatus (TAXT plus). Improve essentials of casting & In-Vitro release profile of drug in saliva was obtained by formulation Fc3 (96.2%). Buccal absorption studies showed that 39.2% of drug absorbed within one minute when available to buccal mucosa at pH 5.5, commensurate with explain diethylcarbamazine citrate- medicated chewing gum (DEC-MCG) can be considered as better formulation for buccal drug delivery system in which drug is absorbed buccally and reaches the systemic circulation via jugular vein.
