The effect of paromomycin on the interaction of ribosomal subunits was studied. Paromomycin inhibited the antiassociation activity of initiation factor 3 (IF3). Furthermore, ribosomal subunits were associated to form 70S ribosomes by paromomycin even in the presence of 1 mM Mg(2+). Paromomycin did not inhibit the binding of IF3 to the 30S ribosomal subunits. On the other hand, IF3 bound to the ...
the current treatment of choice for cutaneous leishmaniasis is either parenteral or intralesional antimonial compounds. each of these treatments has its own downfalls which include toxic side effects with the parentral injection and pain at the site of injection with the intralesional injection. in recent years, there has been more focus on paromomycin as an alternative drug; however, current d...
The mechanism conferring resistance to paromomycin in Streptomyces rimosus forma paromomycinus, the producing organism, was studied at the level of both protein synthesis and drug-inactivating enzymes. Ribosomes prepared from this organism grown in either production or nonproduction medium were fully sensitive to paromomycin. A paromomycin acetyltransferase and a paromomycin phosphotransferase,...
Paromomycin, an aminoglycoside, is known to cause several side effects like nephrotoxicity and ototoxicity like other aminoglycosides but tetany has not been reported. Three cases of tetany were detected in the patients of kala-azar treated with paromomycin. They were promptly treated with intravenous 10 per cent calcium gluconate and tetany was relieved immediately and treatment with paromomyc...
BACKGROUND There is a need for a simple and efficacious treatment for cutaneous leishmaniasis with an acceptable side-effect profile. METHODS We conducted a randomized, vehicle-controlled phase 3 trial of topical treatments containing 15% paromomycin, with and without 0.5% gentamicin, for cutaneous leishmaniasis caused by Leishmania major in Tunisia. We randomly assigned 375 patients with one...
This study evaluated the pharmacokinetics of topical creams containing 15% paromomycin ("paromomycin alone") and 15% paromomycin plus 0.5% gentamicin (WR 279,396) in patients with cutaneous leishmaniasis. The investigational creams were applied topically to all lesions once daily for 20 days. Plasma samples were analyzed for simultaneous quantitation of paromomycin and gentamicin isomers and to...
OBJECTIVES To evaluate in vitro interactions between paromomycin sulphate and the antileishmanial drugs meglumine antimoniate, amphotericin B, miltefosine and azithromycin against intracellular Leishmania (Leishmania) infantum chagasi, Leishmania (Viannia) braziliensis and Leishmania (Leishmania) amazonensis amastigotes in peritoneal mouse macrophages. METHODS First, drug susceptibility was a...
In this randomized, double-blinded Phase 2 trial, 30 patients with Leishmania panamensis cutaneous leishmaniasis were randomly allocated (1:1) to receive once daily topical treatment with WR 279,396 (15% paromomycin + 0.5% gentamicin) or Paromomycin Alone (15% paromomycin) for 20 days. The index lesion cure rate after 6 months follow-up was 13 of 15 (87%) for WR 279,396 and 9 of 15 (60%) for Pa...
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 10(5) Cryptosporidium parvum oocysts. From day 0 to day 12 post-infection, one group (n=14) was treated with 200 mg/...
Cryptosporidium parvum, which causes intractable diarrhea and lethal wasting in people with AIDS, occupies an unusual intracellular but extracytoplasmic niche. No reliable therapy for cryptosporidiosis exists, though the aminoglycoside paromomycin is somewhat effective. We report that paromomycin and the related compound geneticin manifest their major in vitro anti-C. parvum activity against in...
