Cat scratch disease. A therapeutic dilemma.

Cat scratch disease, a relatively common infectious disease, is caused by a small gram-negative pleomorphic bacillus. The course of CSD is usually benign and self-limiting and is characterized by tender regional chronic (3 weeks or longer) lymphadenopathy and frequently preceded by a primary skin lesion following cat contact or scratches. Persistence of adenopathy for several months in a generally healthy patient with gradual spontaneous resolution of the enlarged node is the natural course.

Cat-scratch disease and bacillary angiomatosis.

Cat-scratch disease (CSD) was first described by Debré in 1950, yet the causative bacterial agent of CSD remained obscure until 1992, when Bartonella (formerly Rochalimaea) henselae was implicated in CSD by serological and microbiological studies. B. henselae had initially been linked to bacillary angiomatosis (BA), a vascular proliferative disease most commonly associated with long-standing human immunodeficiency virus (HIV) infection or other significant immunosuppression. B. henselae has also been associated with bacillary peliosis, relapsing bacteraemia and endocarditis in humans. Cats are healthy carriers of B. henselae, and can be bacteraemic for months or years. It has recently been demonstrated that B. henselae can be transmitted from cat to cat by the cat flea, but not by direct contact between animals. The author discusses the present state of knowledge on the aetiology, clinical features and epidemiological characteristics of cat-scratch disease and bacillary angiomatosis.

Neuroretinitis in cat scratch disease.

We report a patient with neuroretinitis, whose associated lymphadenopathy, exposure to cats, and strongly positive cat scratch antigen skin tests suggested the diagnosis of cat scratch disease. Cat scratch disease should be added to the list of infectious agents believed to produce the clinical picture of neuroretinitis.

[Disciform keratatis caused by Bartonella henselae infection: detection of a rare ocular complication of cat-scratch disease with PCR].

BACKGROUND: Cat scratch disease (CSD) is a common infectious disease, however its association with a disciforme keratitis is to our knowledge a previously unreported ocular complication. PATIENT: A 65-year old female was treated unsuccessfully with topical antibiotics, acyclovir and corticosteroids for several weeks because of a disciforme keratitis. Repeatedly, microbiological investigations (microscopy and culture) were negative. 16S rDNA-PCR with subsequent DNA-sequencing on material obtained by corneal scrape identified Bartonella henselae. Based on this result we have initiated a treatment with topical cephotaxim and within a short period of time the cornea healed with a paracentral scar. CONCLUSION: 16S rDNA-PCR was very helpful in identifying the intracellular sited bacterium Bartonella henselae as the causative pathogen of an unusual form of disciforme keratitis.

Mucopolysaccharidosis in a domestic short-haired cat--a disease distinct from that seen in the Siamese cat.

A 10-month-old male domestic short-haired cat was examined because of progressive lameness, a broad face with depressed nasal bridge, small ears, corneal clouding, and multiple bone dysplasia. The cat excreted excessive amounts of glycosaminoglycan (a component of connective tissue) in its urine and had evidence of lysosomal storage of glycosaminoglycans in fibroblasts and neurons. Activity of alpha-L-iduronidase, a lysosomal enzyme involved in glycosaminoglycan degradation, was deficient in cultured fibroblasts and leukocytes. The mucopolysaccharidosis was distinct from that seen in Siamese cats in terms of the pathologic changes and the specific enzyme deficiency.

Disseminated hepatic and splenic calcifications following cat-scratch disease.

Patients with cat-scratch disease (CSD) may develop visceral manifestations such as hepatic and splenic granulomas. Normally, the granulomas disappear within 1-5 months. Two previous reports have described the evolution of splenic lesions into small calcifications. We report a case of cat-scratch disease in which long lasting multiple and disseminated hepatic and splenic granulomas evolved into coarse calcifications.

Nutrition and lower urinary tract disease in cats.

Lower urinary tract disease occurs commonly in cats and is often associated with crystal-related disease. Dietary modification is beneficial in managing some of these diseases, including idiopathic cystitis, urolithiasis, and urethral matrix-crystalline plugs. Altering dietary formulation may result in decreasing urinary concentrations of crystallogenic compounds, increasing urinary concentrations fo crystallogenic inhibitors, and diluting urine composition.

Cat scratch disease. Survey on the presence of Bartonella henselae among cats of Tuscany.

To verify the presence of Bartonella henselae-infection in cats living in Tuscany (central Italy) serological and bacteriological surveys were carried out. The blood serum samples of 427 cats, 254 living in private houses and gardens and 173 in public or private catteries, were tested for anti-B. henselae antibodies by indirect immunofluorescence assay (IFA). Among these samples, 35 were examined by IFA to detect antibodies against Bartonella quintana. Bacteriological examinations were performed on the blood samples, collected in EDTA (ethylene diaminetetraacetic acid), of 18 cats (10 seropositive to B. henselae and 8 negative). From each of the same 18 specimens DNA was extracted and used as template in polymerase chain reaction (PCR). The primers p24E and p12B were employed in the PCR assay to amplify a 296 bp fragment of the Bartonella 16S rRNA gene. IFA detected 98 (22.95%) B. henselae-positive serum samples (40-40.82% from cats living in houses and gardens and 58-59.18% from cats of catteries) at different antibody titers (70 at 1:64 titer, 4 at 1:128, 22 at 1:256, 2 at 1:512). Among the 35 sera tested to detect antibodies against B. quintana, 9 (25.71%) resulted positive at 1:64 titer; all these samples showed higher antibody titers to B. henselae. Out of the 26 negative sera, 20 were negative to B. henselae too and 6 had antibodies against B. henselae at 1:64. Hemocultures gave negative results. PCR scored positive with DNA of 4 B. henselae-seropositive cats, two of which belonged to two children with cat scratch disease (CSD).

Cat-scratch disease in veterinary-associated populations and in its cat reservoir in Taiwan.

In Taiwan, the first human case of cat-scratch disease (CSD) was diagnosed by a serologic test in 1998. Since then, no studies have been conducted to understand the epidemiology of the infection in Taiwan. Therefore, this study is the first epidemiologic survey of CSD in cats and humans in this country. Using veterinary-associated individuals as the study population, it was identified that 1.7% of them were seropositive for B. henselae, and residence was the only factor associated with seropositivity. Bartonella species were successfully isolated from 25 (19.1%) of the 131 cats tested. Only B. henselae and B. clarridgeiae were obtained from bacteremic cats. Furthermore, 9.2% of 131 cats were dually-infected with genotypes I and II of B. henselae. It is the highest prevalence of co-infection that has ever been reported worldwide. In cats, the seroprevalence was 23.7% by indirect immunofluorescence antibody assay with B. henselae Houston-1 (type I) as the antigen. When 12 bacteremic but seronegative cats were re-tested by IFA slides coated with B. henselae U-4 antigen (type II), 9 cats were identified to be seropositive. Our study further suggested that using only direct PCR of 16S-23S rRNA intergenic region or the combination of the PCR method and indirect immuno-fluorescence test will be useful to diagnose Bartonella-free cats.

Cat-scratch disease: orthopaedic presentation.

Although cat-scratch disease is not uncommonly treated by pediatricians, it is rarely seen by orthopaedists. In this review of cat-scratch disease, two cases with orthopaedic manifestations are high-lighted. One patient had a positive bone scan in the distal humerus that simulated osteomyelitis on presentation. The second patient presented with a rapidly enlarging soft-tissue mass in the arm that resembled a soft-tissue sarcoma. The diagnosis of cat-scratch disease eventually was made late in the course of management in both cases. Both patients underwent surgical drainage and evacuation of the suppurated lymph node and recovered without sequelae.

Cat-scratch disease: a case report.

Cat-scratch disease is the most common cause of benign lymphadenopathy in children and young adults. A 21-year-old patient presented with a 14-day history of asymptomatic left submental swelling. Clinical and radiographic examination revealed no dental cause. An enlarged, firm nodule was excised. The histopathologic appearance was consistent with cat-scratch disease. This article summarizes the relevant literature and discusses diagnosis and treatment of cat-scratch disease.

Cat-scratch disease simulating Histiocytosis X.

Cat-scratch disease is a self-limited condition commonly causing a benign chronic lymphadenopathy in children. Osteolytic lesions are a rare complication, but have been previously reported. We report a case of a solitary osteolytic lesion of the skull whose clinical, radiographic and pathological features were initially interpreted as being consistent with Histiocytosis X. Subsequently, positive serological titers for Bartonella, a history of a cat-scratch antecedent to the onset of clinical symptoms and review of the original histopathology confirmed the diagnosis of cat-scratch disease. We reviewed the English language literature on osteolytic lesions associated with cat-scratch disease and compare the current case with those previously reported.
