Rickettsial infections of a spotted fever group have recently been experience in Japan. Although there have been 50 cases reported by this time, they were exclusively distributed in the areas along the Pacific coast. We report in this paper the first case of spotted fever group rickettsiosis in Shimane prefecture, an area faced to the Japan Sea. A 57 year-old man with high fever, general fatigue and rash was admitted to the hospital of Shimane Medical University at the end of September 1987, who had been treated with cefaclor for a few days without effect before his visit to the University Hospital. Physical examination revealed erythematous eruption, eschar on the left side of the abdomen, and generalized lymphadenopathy. Hepatosplenomegaly was not detected. Laboratory studies showed normal leukocyte counts with relative lymphopenia, high ESR and increased CRP. Transaminase levels were slightly elevated. Paul-Bunnel and Weil-Felix tests resulted in negative. Specific immunofluorescence tests demonstrated that IgG and IgM antibodies of acute-phase serum to Rickettsia japonica, a spotted fever group rickettsia isolated from patients in Japan, were not detected, while both IgG and IgM antibody titers of convalescent-phase serum increased to 1:320. Convalescent-phase serum reacted at significantly lower titers with R.typhi as well as other pathogenic spotted fever group rickettsiae. The patient was treated with ofloxacin for six days and then with combination of ofloxacin and minocycline. It should be noted that clinical symptoms such as high fever and general fatigue disappeared during a single therapy with ofloxacin.(ABSTRACT TRUNCATED AT 250 WORDS)

To clarify the clinical manifestations of pediatric Japanese spotted fever (JSF), which remain unclear, we retrospectively reviewed the records of 9 consecutive hospitalized children 5 boys and 4 girls aged 0-15 years (median: 2.3) whose diagnosis was patients with JSF who were serologically confirmed from April 2008 to October 2009. We initially studied the polymerase chain reaction (PCR) assay validity for specific Rickettsia japonica DNA in the blood. We also studied febrile duration, the history of contact with tick-infested areas, body temperature, eschars at tick bite sites, skin rash, treatment drugs, and laboratory data. Five of the 9 (56%) had positive PCR tests. Prehospitalization febrile duration was 1-5 days. Five had had contact with tick-infested areas and 4 had not despite living near such areas. Body temperature was 40 degrees C in 7. Only 4 had eschars at bite sites. Characteristic spotted palmar and/or plantar erythema seen in 8 was useful in diagnosis. Laboratory studies showed typical hyponatremia of < 135mEq/L in 6 JSF was diagnosed easily at hospitalization in 7. Diagnosis in a 2-month-old infant proved difficults, however, worsening the child's condition and causing hepatosplenomegaly, thrombocytopenia, anemia, and hyperferritinema. The infant was treated with high-dose gamma-globulin and azithromycin (AZM) followed by minocycline (MINO). Another case was difficult to diagnose due to clinical manifestations consistent with Kawasaki disease. The child was treated with high-dose gamma-globulin and AZM. Three of the 9 were treated with MINO alone and 4 with combined MINO and new quinolones. Fever was resolved within 2 days of treatment in all cases. Our findings show that children with high fever and spotted palmar and/or plantar erythema should be treated immediately for JSF in prevalent areas, even in the absence of eschars.
