Will the real agent of cat-scratch disease please stand up?

Cat-scratch disease has been recognized since 1889 in association with the oculoglandular syndrome of Parinaud. The epidemiologic association with cats was first made in 1931 and further substantiated throughout the years, refining the interaction predominantly to kittens. Putative infectious agents have included numerous species of bacteria, chlamydiae, and viruses. The cultivation of Afipia spp. in the late 1980s appeared to answer the mystery of the identity of the agent. However, even more recent analysis, which has combined traditional microbiology, molecular methods, and additional epidemiology, has demonstrated that Bartonella (Rochalimaea) henselae is the definitive agent of cat-scratch disease. Our understanding of the pathogenesis of cat-scratch disease and other diseases caused by Bartonella species is incomplete and the spectrum of diseases continues to emerge. We review historic and modern efforts to understand the etiology of cat-scratch disease and related syndromes.

Oculoglandular disease of parinaud. A manifestation of cat-scratch disease.

Among patients with cat-scratch disease, the oculoglandular form is the most common unusual manifestation. This condition, seen in 14 of 585 patients with the infection encountered in a private pediatric practice over a span of 23 years, belongs in the syndrome of the oculoglandular disease of Parinaud. Most of the 14 patients described were only mildly ill and had but little discomfort. All patients recovered without residuals. Diagnosis is based on four criteria: exposure to a cat, usually an immature one; the presence of a localized granuloma of the eye; the presence of preauricular lymphadenopathy; and a positive skin test to cat-scratch antigen of known potency. Several unusual features, never before described, of oculoglandular disease due to cat-scratch disease are submitted.

Pulmonary arterial disease in cats seropositive for Dirofilaria immitis but lacking adult heartworms in the heart and lungs.

OBJECTIVE: To determine the prevalence and severity of pulmonary arterial lesions in cats seropositive for heartworms (Dirofilaria immitis) but lacking adult heartworms in the heart and lungs during necropsy. ANIMALS: 630 adult cats from an animal control shelter in Florida. PROCEDURE: Cats were tested for adult heartworms in the heart and pulmonary arteries and antibody against heartworms in the serum. Histologic examination was conducted on the right caudal lung lobe of 24 heartworm- and antibody-positive cats; 24 heartworm-negative and antibody-positive cats; and 24 heartworm-, antibody-, and antigen-negative cats. Wall areas of 10 small to medium-sized pulmonary arteries of each cat were measured and expressed as a proportion of total cross-sectional area. RESULTS: Heartworm infection or seropositive status was significantly and strongly associated with seventy of medial hypertrophy of pulmonary arterial walls. Heartworm- and antibody-positive cats and heartworm-negative and antibody-positive cats had a significant increase in wall thickness, compared with wall thickness for heartworm- and antibody-negative cats. Heartworm- and antibody-positive cats had the most severe hypertrophy. The proportion with occlusive medial hypertrophy was significantly higher in heartworm- and antibody-positive cats (19/24 [79%]) and heartworm-negative and antibody-positive cats (12/24 [50%]), compared with heartworm- and antibody-negative cats (3/24 [13%]). CONCLUSIONS AND CLINICAL RELEVANCE: Cats with serologic evidence of exposure to heartworms, including those without adult heartworms in the lungs and heart, have a greater prevalence of pulmonary arterial lesions than heartworm-negative cats without serologic evidence of exposure. Additional studies are needed to define the pathogenesis, specificity, and clinical importance of these lesions.

Successful treatment of cat-scratch disease with ciprofloxacin.

Cat-scratch disease is usually a benign, self-limited disease. Infection may be asymptomatic but is commonly associated with painful regional lymphadenitis. Occasionally, disease may result in systemic symptoms and dissemination. Five adult patients, aged 24 to 57 years, were diagnosed as having cat-scratch disease, based on a positive history of cat scratches followed by typical symptoms including painful regional lymphadenitis, malaise, and positive cat-scratch skin tests. Diagnostic evaluations revealed no other cause for the lymphadenitis. Three patients had not received prior treatment with antibiotics, and two patients had failed to improve on other antibiotics. All five were treated with oral ciprofloxacin, 500 mg by mouth, twice daily. All patients had dramatic improvement in symptoms within a few days and none has relapsed during follow-up. This is the first report of successful treatment of cat-scratch disease with ciprofloxacin, which appears to be an effective therapy for cat-scratch disease in adults.
