[Three children with systemic cat scratch disease].

Three girls with systemic cat scratch disease, aged 10, 13 and 9 years, were reported. They presented a prolonged fever and back pain in the early stage of the disease, and had no regional lymphadenopathy. Two of them had hepatosplenic granulomas, one with multiple 5 mm hypoechoic lesions in the liver and spleen, and the other with a single 2.5 cm hypodense lesion in the left hepatic lobe. The latter patient underwent a partial left hepatic lobectomy. All patients had elevated titers of antibodies to Bartonella henselae. Polymerase chain reaction detected B. henselae DNA in tissue specimens of the patient who underwent a hepatic lobectomy. Cat scratch disease should be recognized as a cause of fever of unknown origin because the prevalence of B henselae infection might be higher in Japan.

Recent Advances in Diagnosis and Treatment of Cat Scratch Disease.

The cause of cat scratch disease (CSD), first described in France in 1950 and in the United States in 1951, was unknown until 1983 when the bacterium in lymph nodes was detected using a Warthin-Starry silver stain. Afipia felis has been an infrequent cause of CSD since1988, when this gram-negative bacterium was first isolated from 10 patients with CSD. In 1992 Bartonella organisms were isolated from immunocompetent and immunocompromised patients. An indirect fluorescent antibody test to detect bartonella-specific serum immunoglobulins was developed in 1992. Since then multiple studies have shown that three Bartonella species may produce either CSD in humans, usually Bartonella henselae or Bartonella clarridgeiae, or bacteremia in healthy cats. Also, these two bacteria and Bartonella quintana cause bacillary angiomatosis, bacillary peliosis, or relapsing bacteremia in humans. Cats are healthy carriers of Bartonella organisms and may be bacteremic for months to years. Cat-to-cat transmission of Bartonella organisms involves the cat flea in absence of direct contact transmission. CSD is the most common cause of regional lymphadenitis in children and adolescents. Present knowledge on the etiology, clinical features, epidemiology, pathogenesis, diagnosis, and management of CSD are presented. Also, brief comments about the etiology, clinical presentation, and treatment of bacillary angiomatosis and bacillary peliosis are provided.

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.

Submacular exudates with serous retinal detachment caused by cat scratch disease.

PURPOSE: To present submacular exudates as a manifestation of cat scratch disease. METHODS: Report of two cases. RESULTS: The first patient, a 34-year-old man, developed submacular exudates with serous retinal detachment ten days after having axillary lymphadenopathy and fever. The second patient, a 30-year-old woman, developed submacular exudates with serous retinal detachment mimicking central serous chorioretinopathy. Fluorescein angiography revealed late staining of the subretinal lesions in both cases. The lesion resolved spontaneously in the first patient, while sulfamethoxazole and trimethoprim was required for the second patient. Both patients had a positive IgG titer for Bartonella henselae. CONCLUSIONS: Submacular exudates with serous retinal detachment can occur in cat scratch disease. Cat scratch disease should be included in the differential diagnosis of submacular exudates with central serous chorioretinopathy.

Multiple scattered granulomatous skin lesions in cat scratch disease.

We report a patient with cat scratch disease who presented with multiple scattered nodular lesions on the legs. Examination of skin biopsy specimens revealed a granulomatous pattern. In our opinion, this is a previously undescribed secondary cutaneous reaction of cat scratch disease. The pathogenesis of this reaction is unclear but some data suggest that the eruption might be caused by a hematogenous spread of cat scratch disease bacteria to the skin. Pathogenetic relationships with so-called bacillary angiomatosis, recently described in patients with acquired immunodeficiency syndrome, are reviewed here.

[Cat-scratch disease: series of 14 cases. The diagnostic usefulness of serology].

BACKGROUND: Disease by cat scratch (CSD) is a syndrome characterized by regional adenopathies following cat scratch or bite. Despite knowing the etiologic agent of the same, there is still controversy in the diagnosis of the syndrome in daily clinical practice. MATERIALS AND METHODS: The cases of CSD diagnosed from 1990 to 1997 with positive serology for Bartonella henselae performed by indirect immunofluorescence were reviewed. RESULTS: In 13 out of the 14 patients studied direct contact with cats was reported. Lymph node involvement corresponded to the following regions: axillary (57%), inguinal (28%), epitroclear (21%), cervical (14%), and periauricular (7%). In 35% of the cases, several territories were involved. In 3 patients the adenopathies were fluctuating. Eleven anatomopathologic studies were performed with 6 diagnoses of granulomatous adenitis, 3 reactive adenitis and 2 purulent adenitis. The serology for Bartonella henselae was positive in all the patients with a range of 1/64-1/256. The evolution was favorable in all the patients. DISCUSSION: Interpretation of the results of serology should be cautions and always related to the clinical and epidemiological picture of the patient. This technique should be considered as another criteria in the diagnosis of cat scratch disease to the detriment of the cutaneous test.

[A case of cat scratch disease: from the clinical pathological point of view].

We described a forty-four-year-old female who was scratched by her cat, and developed lymphadenopathy. Cat scratch disease skin-test was positive. Cat scratch disease is well known, but there are not many reports in Japan. Reports of cat scratch disease will increase as the pathogen was recently detected. Attention must be drawn to zoonosis containing cat scratch disease.

Disseminated cat scratch disease with vertebral osteomyelitis and epidural abscess.

A 5-year-old boy with cat scratch disease presented with fever of unknown origin and osteomyelitis of the thoracic spine and epidural abscess. He did not have localizing signs or symptoms. Computed tomography of the abdomen, which was initially negative, showed hepatosplenic disease. Cat scratch disease has variable systemic presentations and should be included in the differential diagnosis of fever of unknown origin if an epidemiologic risk factor is present.

Cat scratch disease: no longer a diagnostic dilemma.

Cat scratch disease is a relatively common cause of localized lymphadenopathy with about 80% of cases occurring in children. This self-limited infection is caused by a small pleomorphic gram-negative bacillus that has been identified in ocular granulomas, skin and lymph node specimens. Unusual manifestations of the disease, such as the oculoglandular disease of Parinaud, encephalopathy, or severe systemic disease, occur in about 12% of patients. Management consists of symptomatic treatment, occasionally aspiration of a node or selected antibiotic therapy in moderate to severely ill patients. 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. 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).

Fine needle aspiration cytology of cat scratch disease.

The cytologic features of cat scratch disease diagnosed by fine needle aspiration cytology of a right inguinal lymph node in a 23-year-old woman are reported. Characteristic granulomas, with peripherally palisading epithelioid histiocytes and centrally located neutrophils, and an associated polymorphic cell population were observed. The cytologic pattern closely parallels the expected histopathologic findings and therefore can suggest the diagnosis in unsuspected cases or can confirm the clinical impression. The cytologic differential diagnosis and a discussion of other granulomatous lymphadenitis are presented.

Use of silver staining (dieterlé's stain) in the diagnosis of cat scratch disease.

Lymph node involvement in cat scratch disease is characterized by a granulomatous lymphadenitis with micro-abscesses. Recently, it has been shown that the possible aetiological agent is a micro-organism which stains with some silver stains. In this study 60 lymph nodes were studied from 60 patients, using a modified Dieterlé's stain. In 40 cases (66%) rod-shaped bacilli with rounded extremities were observed. They were negative both with the Gram and Ziehl-Neelsen stains. Since such micro-organisms were demonstrated in the majority of the nodes examined, it can be concluded that silver stains are appropriate for the diagnosis of this condition.

Prevalence of Bartonella henselae bacteremia, the causative agent of cat scratch disease, in an Australian cat population.

In order to determine the prevalence of Bartonella henselae becteremia in an Australian cat population we examined blood cultures on a group of Sydney cats. Cats referred to the Concord Animal Hospital for euthanasia were selected randomly for blood culture and serum sampling. Blood samples were lysed and centrifuged and then cultured for up to five weeks. Suspicious colonies were identified biochemically as probable B. henselae. Selected isolates were confirmed as B. henselae using the polymerase chain reaction. Of the cats accrued throughout Sydney, 27/77 (35%) were culture positive for B. henselae, of these 24/59 (40%) were feral cats and 3/18 (16%) were domestic. Most cats in the study were younger than one year (mean 9.9 months). Our study demonstrates that bacteremia with B. henselae is common in the metropolitan cat population and suggests that it is particularly prevalent among feral animals. By contrast Cat Scratch Disease (CSD) is a relatively uncommon clinical diagnosis in the Australian population. Explanations for this discrepancy may include poor transmission, low bacterial virulence and underdiagnosis. It is possible that feral animals are a greater potential risk source for this infection than domestic cats.

[Cat-scratch disease as cause of Lymphadenitis colli].

Cat-scratch Disease as Cause of Lymphadenitis colli. Cat-scratch disease is a frequent cause of lymphadenitis colli. It mainly affects children and adolescents younger than 21 years. Since the clinical picture is not characteristic, a history of contact to cats or kittens is highly valuable for diagnosing the disease. Major aspects of the disease concerning epidemiology, diagnostic procedures, clinical presentation and therapy are discussed.

[Sudden sight impairment revealing a cat-scratch disease: report of three cases].

UNLABELLED: Cat-scratch disease is a frequent but innocuous cause of chronic lymphadenopathy in children. Numerous atypical forms have been described. We report three cases of acute sight impairment revealing a cat-scratch disease. BACKGROUND: A 13 year-old boy and two girls aged 10 and 13 suffered from a sudden bilateral sight impairment with papillary edema, with fever in two cases. Neurological examinations, X-rays and lumbar puncture results were found normal. However, all patients were tested positive to Bartonella Henselae. Antibiotic and anti-inflammatory treatments were efficient in two cases. CONCLUSION: Cat-scratch disease can be characterized by an isolated and acute sight impairment with a stellate neuroretinitis. The potency of antibiotic treatments is debatable.
