Abstract

Canine heartworm disease is caused by infection with Dirofilaria immitis, a filarial nematode that resides in the pulmonary arteries and occasionally in the right heart chambers of infected dogs. Here the authors evaluated the effect of a combination of doxycycline (10 mg/kg/sid for 30 days) and ivermectin–pyrantel(6μg/kg [DOSAGE ERROR CORRECTED] of ivermectin+5mg/kg of pyrantel every 15 days for 180 days) on microfilariemia, antigenemia and parasite load at echocardiography in naturally infected dogs from an endemic region of Italy. Dogs were examined monthly for 6 months and followed-up 4 months later. One hundred percent of dogs became negative for circulating microfilariae by day 90, while 8/11 (72.7%) of dogs became antigen-negative by day 300. Of the 7 dogs that were positive for visualization of parasites at echocardiography, 6 (85.7%) became negative by day 300. Treatment was well-tolerated by all dogs. These results suggest that a combination of doxycycline and ivermectin is adulticide in dogs with D. immitis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A combination of doxycycline (10 mg/kg die for 30 days) and ivermectin (6 mcg/kg every 15 days for 6 months) has a potential efficacy, as high as 73%, in the adulticide therapy in dogs infested with Dirofilaria immitis.

    “Therefore, it has been suggested that a combination of doxycycline (10 mg/kg die for 30 days) and ivermectin (6 mcg/kg every 15 days for 6 months) has a potential efficacy, as high as 73%, in the adulticide therapy in dogs infested with D. immitis[107,108].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
