A rare case of human pulmonary dirofilariasis with nodules mimicking malignancy: approach to diagnosis and treatment.

J Cardiothorac Surg 2018 Jun 11;13(1):65. Epub 2018 Jun 11.

Department for the Treatment and Study of Cardiothoracic Diseases and Cardiothoracic Transplantation, IRCCS ISMETT, Via Tricomi 5, Palermo, Italy.

Background: Human pulmonary dirofilariasis is a rare zoonosis caused by the dog worm Dirofilaria spp., a parasite transmitted by mosquitos and resulting in peripheral lung nodules. The filarial nematode enters the subcutaneous tissue, travels to the right ventricle and dies causing a small pulmonary infarction that may embolize through the pulmonary vessels and may appear as a solitary nodule.

Wolbachia, doxycycline and macrocyclic lactones: New prospects in the treatment of canine heartworm disease.

Vet Parasitol 2018 Apr 9;254:95-97. Epub 2018 Mar 9.

Department of Veterinary Science, University of Parma, Parma, Italy.

Melarsomine dihydrochloride (Immiticide®, Merial) is the only approved adulticidal drug for the treatment of canine heartworm disease (HWD). However, in cases where arsenical therapy is not possible or is contraindicated, a monthly heartworm preventive along with doxycycline for a 4-week period, which targets the bacterial endosymbiont Wolbachia, might be considered. There are published reports on the efficacy of ivermectin and doxycycline in both experimentally and naturally infected dogs, but no data on the use of other macrocyclic lactones (MLs) with a similar treatment regime.

Vet Parasitol 2018 Apr 25;254:178-182. Epub 2018 Feb 25.

Department of Comparative Diagnostic and Population Medicine, College of Veterinary Medicine, University of Florida, 2015 SW 16th Avenue, Gainesville, FL 32610-0123, USA. Electronic address:

Patient-side test kits for detecting antigenemia in dogs associated with sexually mature female heartworms (Dirofilaria immitis) have been available for three decades, and these tests are continually updated and improved. To define the sensitivity (Se) and specificity (Sp) of contemporary antigen detection tests against cardiopulmonary D. immitis burden, we evaluated five patient-side kits-Anigen Rapid One Step (Bio note), SNAP 4Dx Plus Test Kit (IDEXX), WITNESS Heartworm Canine Heartworm Antigen Test Kit (Zoetis), VetScan Canine Heartworm Rapid Test (Abaxis), and Solo Step CH Canine Heartworm Antigen Test (Heska), and one microplate ELISA (DiroCHEK; Zoetis), using archived canine sera divided into five subclasses of female worms (0, 1-5, 6-20, 21-40, and >40).

Detection of Dirofilaria immitis antigen and antibodies against Anaplasma phagocytophilum, Borrelia burgdorferi and Ehrlichia canis in dogs from ten provinces of China.

Acta Parasitol 2018 Jun;63(2):412-415

Jiangsu Co-innovation Center for Prevention and Control of Important Animal Infectious Diseases and Zoonoses, Yangzhou University College of Veterinary Medicine, Yangzhou, Jiangsu, 225009, People's Republic of China.

Despite the fact vector-borne diseases (VBDs) have been increasingly reported in dogs worldwide, there are only limited reports on VBDs in dogs in China with most being based on molecular detection of active infections. To provide further data on the exposure of dogs in China to VBD agents, we used commercial immunochromatographic assays to test plasma from 637 apparently healthy indoor and breeding colony dogs from 21 veterinary clinics in 10 provinces in China and a commercial dog breeding facility for circulating antigen of Dirofilaria immitis, and for circulating antibodies against Ehrlichia spp., Anaplasma spp. Read More

Dirofilaria immitis and Angiostrongylus vasorum: The current situation of two major canine heartworms in Portugal.

Vet Parasitol 2018 Mar 31;252:120-126. Epub 2018 Jan 31.

CIISA, Faculdade de Medicina Veterinária, Universidade de Lisboa, Avenida da Universidade Técnica, 1300-477 Lisboa, Portugal.

Cardiopulmonary nematodes are life-threatening pet parasites increasingly reported throughout Europe, with overlapping endemic areas. Dirofilaria immitis is a mosquito-borne whilst Angiostrongylus vasorum is a snail-borne pathogen. Both adult nematodes reside in the pulmonary arteries and right cardiac ventricle of domestic and wild canids, causing a wide spectrum of clinical presentations ranging from cough, dyspnoea and exercise intolerance to severe vascular and pulmonary disease with hearth failure that may lead to death.

Prime detection of Dirofilaria immitis: understanding the influence of blocked antigen on heartworm test performance.

Parasit Vectors 2018 03 20;11(1):186. Epub 2018 Mar 20.

Department of Veterinary Pathobiology, Center for Veterinary Health Sciences, Oklahoma State University, Stillwater, OK, USA.

Detection of circulating antigen of Dirofilaria immitis has been a mainstay of identifying heartworm infection in clinical practice for the past three decades. Several validated commercial antigen tests have very good sensitivity, specificity, and positive predictive values, especially when used in patients for which heartworm infection is likely. In some dogs and cats infected with heartworm, antigen may not be available for detection although present in the patient sample; heat pretreatment of these samples reveals the antigen, changing the false negative to positive.

Can P-glycoprotein and β-tubulin polymorphisms be used as genetic markers of resistance in Dirofilaria immitis from Rio de Janeiro, Brazil?

BMC Res Notes 2018 Feb 23;11(1):152. Epub 2018 Feb 23.

Laboratório de Imunomodulação e Protozoologia, Instituto Oswaldo Cruz, Fiocruz, Av. Brasil 4365, Rio de Janeiro, RJ, 21040-360, Brazil.

Objective: Dirofilaria immitis, the causative agent of canine heartworm infection, is worldwide the most important filarid to affect domestic dogs. Prevention of this infection is done by macrocyclic lactones, but some reports on the lack of efficacy have been published. Although the actual cause of resistance is unknown, single nucleotide polymorphisms (SNPs) on a P-glycoprotein ABC transporter and β-tubulin genes have been pointed out as candidates for genetic markers of resistance.

Evaluation of heat-treating heartworm-positive canine serum samples during treatment with Advantage Multi for Dogs and doxycycline.

Parasit Vectors 2018 02 20;11(1):98. Epub 2018 Feb 20.

University of Georgia, College of Veterinary Medicine, Athens, GA, USA.

Background: The use of heat-treatment in canine and feline serum has been hypothesized to break the formation of antigen-antibody complexes, thereby freeing the heartworm antigen allowing for detection by commercially available heartworm antigen kits. While studies have analyzed the effect of heat-treating serum and plasma samples in the detection of heartworm antigen, these studies have not utilized necropsy verified results for validation. This study evaluated the use of heat-treating serum samples in experimentally infected dogs during adulticidal treatment in comparison with necropsy adult heartworm recovery. Read More
