Objectives: To evaluate the efficacy of nitazoxanide and paromomycin in biliary tract cryptosporidiosis in an immunosuppressed Mongolian gerbil (Meriones unguiculatus) model.. Methods: Gerbils (1-month-old) were dexamethasone-immunosuppressed for 10 days and challenged orally with 105 Cryptosporidium parvum oocysts. From day 0 to day 12 post-infection, one group (n = 14) was treated with 200 mg/kg/day nitazoxanide and another (n = 15) with 100 mg/kg/day paromomycin. Infection and efficacy of nitazoxanide and paromomycin were assessed by measuring oocyst shedding in faeces, biliary tract and ileum histological examination.. Results: In nitazoxanide-treated and paromomycin-treated groups as compared with untreated animals (P , 0.05), oocyst shedding was partially suppressed in a similar manner (P , 0.05). Parasites were present in histological sections of the ileal mucosa of 16/16 infected untreated animals versus 3/14 and 6/15 in the nitazoxanide-treated and the paromomycin-treated groups, ...

Patients should be counseled that antibacterial drugs including Paromomycin Sulfate Capsules should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Paromomycin Sulfate Capsules is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Paromomycin Sulfate Capsules or other antibacterial drugs in the future ...

When Venus was used as a GOI with this system, a positive correlation was found between paromomycin resistance and Venus fluorescence, indicating that expression from the two ORFs is coupled. It initially seemed possible that a mechanism such as stop-codon read through (Jackson et al. 2012) might result in expression of the GOI and APHVIII products as a single fusion protein that provides paromomycin resistance. However, this appears not to be the case, because the method works equally well when two or three different stop codons are inserted between the ORFs, and/or the ORFs are placed out-of-frame, and Western blotting detected no such fusion products. Thus, it seems most likely that APHVIII is translated by post-termination reinitiation (Kozak 2007; Skabkin et al. 2013), in which the ribosome remains associated with the mRNA after termination, continues scanning, and reinitiates translation at a downstream (or, occasionally, upstream: Skabkin et al. 2013) AUG. Such events have been well ...

Paromomycin is an aminoglycoside that is active against Gram-negative and many Gram-positive bacteria as well as some protozoa and cestodes. It is out of use as an antibiotic but was licensed in 2007 in India as an effective, well tolerated and affordable treatment for visceral leishmaniasis (VL) at a dose of 11mg/kg (base) for 21 days. Currently, the non-profit group Drugs for Neglected Diseases Initiative is conducting studies on paromomycin (as monotherapy and in combination) in VL in Africa, and the Institute for OneWorld Health is conducting a Phase IV study in India. Paromomycin in combination with sodium stibogluconate has proven to be effective in African and Indian VL and improves survival in African VL. To prevent the emergence of drug-resistant leishmaniasis in areas of anthroponotic transmission (India and Africa), paromomycin should be used as part of combination therapy for VL. Further trials testing different combinations are much needed. In addition, the distribution of ...

Paromomycin and neomycin are aminoglycoside antibiotics, which are effective against a number of aerobic and facultative anaerobic gram-positive bacilli and staphylococci (9, 11). Paromomycin and neomycin differ in chemical structure by the functional group attached to the C′ 6 of ring 1. Paromomycin has a hydroxyl group at this position, while neomycin possesses an amino group (20).. Both antibiotics bind specifically to the 30S ribosomal subunit (20). They interact with the 16S rRNA of the ribosome within an internal loop of the decoding site (12, 16, 18). Binding to this region results in a conformational change of the conserved bases within the loop of the A-site, which facilitates high-affinity binding between the rRNA of the internal loop and rings I and II of the aminoglycoside antibiotic (7, 8, 15). The tightly bound antibiotic contributes to codon misreading and mistranslation of mRNA.. Previous work with a number of structurally different inhibitors of 50S subunit function has ...

A randomized vehicle-controlled phase 3 trial of topical PM 15% vs. PM 15% + GM 0.5% vs. vehicle control was conducted in Tunisian patients with CL due to Leishmania major. 375 patients were randomized. Patients had from 1-5 lesions each. Lesions were treated daily for 20 days.

Background: Improved treatment approaches are needed for visceral leishmaniasis. We assessed the efficacy and safety of three potential short-course combination treatments compared with the standard monotherapy in India. Methods: Standard treatment (1 mg/kg amphotericin B infusion on alternate days for 30 days, total dose 15 mg/kg) was compared with three drug combinations (single injection of 5 mg/kg liposomal amphotericin B and 7-day 50 mg oral miltefosine or single 10-day 11 mg/kg intramuscular paromomycin; or 10 days each of miltefosine and paromomycin) in an open-label, parallel-group, non-inferiority, randomised controlled trial in two hospital sites in Bihar, India. Patients aged 5-60 years with parasitologically confirmed visceral leishmaniasis were randomly assigned one of the four treatments by the trial statistician using a computer-generated list. Clinical assessments were done at the end of treatment (15 days on combination treatment; 31 days for standard treatment) and after 45 ...

The Institute for OneWorld Health announced today it has received Orphan Drug Designation from the two leading regulatory agencies in the world, the FDA and the European Agency for the Evaluation of Medicinal Products (EMEA), for paromomycin to treat visceral leishmaniasis (VL).

The serious biological consequences of metal toxicity are well documented, but the key modes of action of most metals are unknown. To help unravel molecular mechanisms underlying the action of chromium, a metal of major toxicological importance, we grew over 6,000 heterozygous yeast mutants in competition in the presence of chromium. Microarray-based screens of these heterozygotes are truly genome-wide as they include both essential and non-essential genes. The screening data indicated that proteasomal (protein degradation) activity is crucial for cellular chromium (Cr) resistance. Further investigations showed that Cr causes the accumulation of insoluble and toxic protein aggregates, which predominantly arise from proteins synthesised during Cr exposure. A protein-synthesis defect provoked by Cr was identified as mRNA mistranslation, which was oxygen-dependent. Moreover, Cr exhibited synergistic toxicity with a ribosome-targeting drug (paromomycin) that is known to act via mistranslation, while

A 40-year-old NIH male scientist camped and fished in a remote lake in Alaska. On his return, he developed diarrhea, cramps, and loose stools without blood or mucus in the absence of fever and was diagnosed with giardiasis. A 3-year-old female living in the Florida Keys complained of intermittent stomachaches over a 2-month period. Her stools were variably loose. The patient was diagnosed with giardiasis, which led to examination of her mother, father, and brother, who were mildly symptomatic; all 3 were subsequently diagnosed with giardiasis. The childs only exposure was from swimming in a local community pool. A 40-year-old male from Mexico, who resided in Virginia and worked as a cook in a fast food restaurant, was diagnosed with giardiasis. He denied any symptoms and was not allowed to prepare food. Treatment with metronidazole, nitazoxanide, and albendazole failed to eradicate the infection. He was successfully treated with the combination of paromomycin and metronidazole.. ...

We have identified a novel tRNA methyltransferase in Saccharomyces cerevisiae that we designate Trm9. This enzyme, the product of the YML014w gene, catalyzes the esterification of modified uridine nucleotides, resulting in the formation of 5-methylcarbonylmethyluridine in tRNA(Arg3) and 5-methylcarbonylmethyl-2-thiouridine in tRNA(Glu). In intact yeast cells, disruption of the TRM9 gene results in the complete loss of these modified wobble bases and increased sensitivity at 37 degrees C to paromomycin, a translational inhibitor. These results suggest a role for this potentially reversible methyl esterification reaction when cells are under stress ...

Digoxin can interact with a wide range of over-the-counter and prescription medications. Certain drugs interact so badly that they should not usually be given to someone taking digoxin. They include the gout medicine colchicine, the strong anti-nausea drug dolasetron (Anzemet), the anti-arrhythmic drug dronedarone (Multaq) and the multiple sclerosis medicine fingolimod (Gilenya). Milnacipran (Savella), used to treat fibromyalgia, can increase the risk of dizziness and fainting and irregular heart rhythms in conjunction with digoxin. The antibiotics neomycin and paromomycin can lower digoxin levels unacceptably.. Other interactions can also be troublesome and should be discussed with the physician.. Antacids, for example, may diminish the proper absorption of digoxin. So can certain diarrhea medicines.. A number of other medications, such as amiodarone (Cordarone), propafenone (Rythmol) and quinidine drugs, may make Lanoxin more toxic.. So can Sandimmune, used to prevent transplant ...

Leishmaniasis is a complex disease, with visceral and cutaneous manifestations, and is caused by over 15 different species of the protozoan parasite genus Leishmania. There are significant differences in the sensitivity of these species both to the standard drugs, for example, pentavalent antimonials and miltefosine, and those on clinical trial, for example, paromomycin. Over 60% of patients with visceral leishmaniasis in Bihar State, India, do not respond to treatment with pentavalent antimonials. This is now considered to be due to acquired resistance. Although this class of drugs has been used for over 60 years for leishmaniasis treatment, it is only in the past 2 years that the mechanisms of action and resistance have been identified, related to drug metabolism, thiol metabolism, and drug efflux. With the introduction of new therapies, including miltefosine in 2002 and paromomycin in 2005-2006, it is essential that there be a strategy to prevent the emergence of resistance to new drugs; ...

Cryptosporidium is a ubiquitous protozoan parasite causing gastrointestinal disorder in various hosts worldwide. The disease is self-limiting in the immunocompetent but life-threatening in immunodeficient individuals. Investigations to find an effective drug for the complete elimination of the Cryptosporidium infection are ongoing and urgently needed. The current study was undertaken to examine the anti-cryptosporidial efficacy of curcumin in experimentally infected mice compared with that of paromomycin. Oocysts were isolated from a pre-weaned dairy calf and identified as Cryptosporidium parvum using a nested- polymerase chain reaction (PCR) on Small subunit ribosomal ribonucleic acid (SSU rRNA) gene and sequencing analysis ...

Although Blastocystis is one of the most common enteric parasites, there is still much controversy surrounding the pathogenicity and potential treatment options for this parasite. In this review we look at the evidence supporting Blastocystis as an intestinal pathogen as shown by numerous case studies and several in vivo studies and the evidence against. We describe the chronic nature of some infections and show the role of Blastocystis in immunocompromised patients and the relationship between irritable bowel syndrome and Blastocystis infection. There have been several studies that have suggested that pathogenicity may be subtype related. Metronidazole is the most widely accepted treatment for Blastocystis but several cases of treatment failure and resistance have been described. Other treatment options which have been suggested include paromomycin and trimethroprim- sulfamethoxazole.

Staphylococcus aureus quickly develops resistance to antibiotics and poses a significant health threat to humans. New antibiotic targets are needed for the development of new antibiotics. Trans-translation has important roles in maintaining bacterial viability. Small molecules, KKL-35 and KKL-40, were recently identified as specific inhibitors of trans-translation. We have investigated the roles of trans-translation on S. aureus viability and the potential of KKL-35 and KKL-40 as antibiotics. We find that KKLs show bactericidal activity against multiple S. aureus strains at relatively low concentration. We also find that sub-lethal doses of KKLs make S. aureus more susceptible to antimicrobials. Neither KKL-35 nor KKL-40 are cytotoxic to human HeLa cells. Unfortunately, KKL-40 is inactivated by human serum. Therefore, new inhibitors will need to be identified in future studies. Notably, the development of resistance by S.aureus against KKLs remains at a low level. Therefore trans-translation is ...

Background: Miltefosine has been used successfully to treat visceral leishmaniasis (VL) in India, but it was unsuccessful for VL in a clinical trial in Brazil. Methods: To identify molecular markers that predict VL treatment failure whole genome sequencing of 26 L. infantum isolates, from cured and relapsed patients allowed a GWAS analysis of SNPs, gene and chromosome copy number variations. Findings: A strong association was identified (p = 0·0005) between the presence of a genetically stable L. infantum Miltefosine Sensitivity Locus (MSL), and a positive response to miltefosine treatment. The risk of treatment failure increased 9·4-fold (95% CI 2·11-53·54) when an isolate did not have the MSL. The complete absence of the MSL predicted miltefosine failure with 0·92 (95% CI 0·65-0·996) sensitivity and 0·78 (95% CI 0·52-0·92) specificity. A genotyping survey of L. infantum (n = 157) showed that the frequency of MSL varies in a cline from 95% in North East Brazil to ,5% in the South ...

Unique bacterial process, trans-translation, has been studied to be an important process in many bacteria. However, there was nothing known about the significance of this process in mycobacteria, especially in relation to drug susceptibility. Consistent with findings in Escherichia coli, Salmonella typhimurium, and Synechocystis sp., we found that interfering with the expression of tmRNA and the smpB gene (critical components of trans-translation) in Mycobacterium smegmatis caused increased bactericidal activity of antimicrobial agents that target the ribosomes. Moreover, exposure to ribosome inhibitors increased the expression of tmRNA. This increase was driven by the tmRNA gene promoter which activity seemed to utilize a de-repression mechanism. Not only is trans-translation important to the bacterial response to ribosome inhibitors, evidence from this laboratory suggests that trans-translation is essential in mycobacteria. Thus, we believe that trans-translation may represent a new important ...
