Recently cases of tsutsugamushi disease have been reported in various areas in Japan. We met a case infected in a rural area, Sennan of Osaka prefecture. The patient suffered from high fever, left axillary lymphadenitis. At his left elbow an eschar was detected, so tsutsugamushi disease was suspected, despite no rash nor CRP elevation. By indirect immunofluorescence (IF) method, the diagnosis was confirmed. At an early stage (the fifth day after onset) he was followed by probable DIC, remitted successfully by administration of minocycline. For 20 years tsutsugamushi disease has not been reported in Osaka prefecture. This case is the second one and the first child case in Wakayama prefecture. Epidemiologic assessments may need to be investigated in Osaka and Wakayama Prefecture.

Hantaviruses, the causative agents of HFRS, have become more widely recognized. Epidemiologic evidence indicates that these pathogens are distributed worldwide. People who come into close contact with infected rodents in urban, rural and laboratory environments are at particular risk. Transmission to man occurs mainly via the respiratory tract. The epidemiology of the hantaviruses is intimately linked to the ecology of their principal vertebrate hosts. Four distinct viruses are now recognized within the hantavirus genus and that number is likely to increase to six very soon; however, further investigations are necessary. Much more work is still needed before we fully understand the wide spectrum of clinical signs and symptoms of HFRS as well as the pathogenicity of the different viruses in the hantavirus genus of the Bunyaviridae family. HFRS is difficult to diagnose on clinical grounds alone and serological evidence is often needed. A fourfold rise in IgG antibody titer in a 1-week interval, and the presence of the IgM type of antibodies against hantaviruses are good evidence for an acute hantavirus infection. Physicians should be alert for HFRS each time they deal with patients with acute febrile flu-like illness, renal failure of unknown origin and sometimes hepatic dysfunction. Especially the mild form of HFRS is difficult to diagnose. Acute onset, headache, fever, increased serum creatinine, proteinuria and polyuria are signs and symptoms compatible with a mild form of HFRS. Differential diagnosis should be considered for the following diseases in the endemic areas of HFRS: acute renal failure, hemorrhagic scarlet fever, acute abdomen, leptospirosis, scrub typhus, murine typhus, spotted fevers, non-A, non-B hepatitis, Colorado tick fever, septicemia, dengue, heartstroke and DIC. Treatment of HFRS is mainly supportive. Recently, however, treatment of HFRS patients with ribavirin in China and Korea, within 7 days after onset of fever, resulted in a reduced mortality as well as shortened course of illness.

A 64-year-old male was admitted to our division because of fever. After admission, the patient was given beta-lactam antibiotics intravenously because he had no eruption and eschar. However, the fever continued, and he became unconsciousness and DIC appeared. We diagnosed the patient as Tsutsugamushi disease from indirect fluorescent antibody technique. Minocycline was excellently effective. Several reports of Tsutsugamushi disease without eruption have been given, so we must always be careful of Tsutsugamushi disease.

We compared the severity of clinical symptoms and laboratory test results of tsutsugamushi disease patients in Oita Prefecture according to the serotype of infected R. tsutsugamushi. Of the 45 patients, except one with the Karp-type, who were suffering in Oita Prefecture between 1992 and 1994, 20 were the Irie-type and 24 were the Hirano-type. There was no apparent difference with regard to clinical symptoms between the two groups of patients. Laboratory tests showed that CRP increased almost equally in the two groups. The ESR level was slightly higher in the Irie-type patients than in the Hirano-type, but did not differ significantly between the two groups. Both leukocyte count in the acute stage and platelet count decreased in the Hirano-type, as compared with those of normal ranges in the Irie-type. GPT values elevated in proportion to the day of illness in the acute stage. This trend continued after the initiation of specific chemotherapy in the Hirano-type. The median GOT, GPT and LDH values were 71, 65 and 709 IU/l for the patients in the Hirano-type, as compared with 37, 36.5 and 546.5 for the patients in the Irie-type, respectively. Above results show that the Hirano-type rickettsiae produces a more severe illness than the Irie-type ricketsia. Platelet count had a significant correlation with ESR, suggesting the pathophysiologic changes leading to disseminated intravascular coagulation, a symptom of severe tsutsugamushi disease. There may be common causes in leukopenia and thrombopenia, as being suggested by the significant correlation between leukocyte count and platelet count.

The spectrum of clinical severity for scrub typhus ranges from inapparent, mild, to severe or fatal. The pathologic changes are focal or disseminated multiorgan vasculitis of the small blood vessels, a fact that helps explain the great diversity of clinical manifestations that can be encountered. We reported a case of scrub typhus with unusual and serious multiorgan involvement, including tubulointerstitial nephritis (TIN) with acute renal failure (ARF), interstitial pneumonitis with adult respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC), liver function impairment, upper gastrointestinal bleeding, prolonged hyperamylasaemia and hyperlipasaemia. Chloramphenicol administration rapidly altered the clinical course, but with sequelae of renal impairment and prolonged hyperamylasaemia and hyperlipasaemia for 10 months.

Clinical features of tsutsugamushi disease (scrub typhus) were analyzed, based on 416 cases reported in Japan in 1998. Three major clinical symptoms: eschar, fever and rash were found in 87%, 98% and 92% of the cases, respectively. Elevated levels of CRP, GOT, GPT and LDH were observed in 96%, 85%, 78% and 91%, respectively. These clinical and laboratory findings were observed in the majority of the cases and considered important for diagnosis. Disseminated intravascular coagulation developed in 21 cases, indicating that scrub typhus can be life threatening. Lymphadenopathy was observed in 51% of the cases. Enlarged lymph nodes were limited to the local sites in 75% of these lymphadenopathy cases and most of these sites were adjacent to eschars. Most eschars were scabbed and located in the abdomen and the lower half of the body, especially the feet. This suggests that these parts are frequently exposed to tsutsugamushi mites. Furthermore, the skin is soft in these parts and covered by cloth. These factors may make it possible for mites to keep biting without being noticed for several hours, long enough for rickettsial transmission. Interestingly, eschar and rash were absent in 14% and 8% of the cases, respectively. This result suggests that the cases without the unique symptoms may have been misdiagnosed as common cold or other febrile illnesses. One hundred and fifty-four suspected cases were not scrub typhus cases by the serological tests. The three major clinical symptoms were present in approximately a half of these negative cases, eschar being observed in approximately 70%. This may suggest the presence of new type of scrub typhus can not be diagnosed by the present laboratory tests. Clinical features of scrub typhus in Japan were well revealed, and information obtained in the present study is useful for improving clinical diagnosis. It should, however, be stressed that there were cases that could not be correctly diagnosed only by the clinical symptoms, suggesting that it is important to improve the serological tests.

Surveillance for scrub typhus was conducted in Japan in 1998 using a questionnaire. A total of 462 cases were reported. Scrub typhus occurred in both the fall and spring in the northern part of Honshu (the main island), and in the fall in the central part of Honshu and on the island of Kyushu. The occurrence of the disease varied with age, gender, and activity. Seventy-six percent of the patients were more than 51 years old, and 36% and 16% of the patients were engaged in farm work and forestry, respectively. Fever, rash, and eschar were detected in 98%, 93%, and 97% of the patients, respectively. Elevated levels of C-reactive protein, aspartate transaminase, and alanine transaminase were detected in 96%, 87%, and 77% of the patients, respectively. Disseminated intravascular coagulation developed in 34 cases and had a unique regional distribution. This study shows the status of scrub typhus in Japan in 1998 and provides important information for diagnosis and prevention.

Scrub typhus is an acute febrile illness caused by infection with Orientia tsutsugamushi transmitted by the bite of larval trombiculid mites (chiggers). A prospective study was conducted in septic shock patients in Maharat Hospital, Nakhon Ratchasima Province, Thailand, from 12 November 2001 to 5 January 2002. Of the 51 septic shock patients studied during the 7 week period, 18 (35.3%) were found to have evidence of scrub typhus infection; 3 patients (16.7%) died. In this study, septic shock caused by Orientia tsutsugamushi is the most prominent (35.3%) in endemic area of scrub typhus. Scrub typhus with septic shock patients results in organ failure: respiratory failure, DIC were predominant, followed by renal and hepatic involvement. Two deaths were due to respiratory failure and one death was as a result of combined respiratory and renal failure. Fever was the most common symptom, followed by headache, myalgia and dyspnea; lymphadenophathy and eschar are common signs. Laboratory findings revealed that almost all of the patients had a mild leukocytosis, reduced hematocrit and thrombocytopenia; SGOT, ALP, direct bilirubin (DB), total billirubin (TB), BUN, Cr were elevated; hypoalbuminemia was noted. Urinalysis showed that 88.9% of the patients had albuminuria. 77.8% of patients had abnormal chest X-rays.

Acute renal failure associated with scrub typhus infection is not rare as previously thought. The possibility of scrub typhus should be borne in mind when patients present with fever and varying degrees of acute renal failure, particularly if an eschar exists, along with a history of environmental exposure in an area like Taiwan, where scrub typhus is endemic. Prompt diagnosis and the use of appropriate antibiotics can rapidly alter the clinical course of the disease and prevent the development of serious or fatal complications. To illustrate the above point, this study reports 3 cases of scrub typhus associated with acute renal failure. They were seen at Chang Gung Memorial Hospital in a 2-year interval. Case 1 was referred from district hospital with clinical features of multiple organ dysfunctions, including shock, fever, acute respiratory failure, acute renal failure, and acute hepatitis. Case 2 was admitted with the chief problems of shock, fever, acute renal failure, and DIC. Case 3 visited our outpatient clinic due to fever, maculopapular rash and acute renal failure. In all these patients, the diagnosis was confirmed using immunofluorescence techniques, which showed that Orientia tsutsugamushi had an IgM titer of 1:80 or greater. Notably, despite having varying degrees of acute renal deterioration, the patients responded very well to doxycycline therapy and recovered completely. Additionally, a total of 4 similar cases of scrub typhus associated with acute renal failure were reviewed from the past literature.

A 65-year-old man was admitted because of high grade fever and cough after 3 days of gathering edible wild plants. Although ceftriaxone was given to him, his symptoms did not improve. His high grade fever escalated after changing the antibiotics (imipenem with erythromycin). His situation further declined with disseminated intravascular coagulation (DIC) and acute respiratory distress syndrome (ARDS). As a result, he was transferred to the Department of Respiratory Medicine 7 days after admission. He was intubated and placed on mechanical ventilation and treated by polymyxin-direct hemoperfusion. The eschar on his chest wall caused us to suspect Tsutsugamushi disease and a blood test confirmed our suspicion. Since the antibodies for Tsutsugamushi were elevated we arrived at the diagnosis of Tsutsugamushi disease with DIC and ARDS. The administration of tetracycline was sufficient to significantly improve his condition. Because its complications are life threatening, when we see a patient with fever and eruptions, it is necessary to keep in mind the possibility of Tsutsugamushi disease. Careful anamnesis and physical examinations are most important for the diagnosis of Tsutsugamushi disease.
