A 41-year-old Japanese male with uncontrolled diabetes mellitus and alcoholic liver dysfunction developed melioidosis after his business trip to Indonesia and Singapore in 1988. His disease started with spiked fever on the following day after extraction of a tooth, and a liver abscess developed, followed by abscesses in the spleen and in the subphrenic space. In spite of splenectomy and intensive antimicrobial treatments for three months, he developed parotitis, prostatitis, and abscess of the right submandibular gland at 5 to 16-month interval. Pseudomonas pseudomallei was isolated from the blood and pus from each abscess. The lung was not involved. At present, he has returned to work, with continued intravenous instillation of imipenem/cilastatin.

We report the first two indigenously acquired cases of melioidosis in Taiwan, diagnosed by positive culture and biochemically identified using the ID 32 GN system (BioMerieux Vitek Inc, Hazelwood, MO, USA). The first patient was a 75-year-old Chinese woman who had not travelled abroad since her arrival from mainland China (San-Tung province) 47 years ago. She presented with spontaneous bacterial peritonitis and hepatitis C-related liver cirrhosis with septic shock. Burkholderia pseudomallei (formerly Pseudomonas pseudomallei) was isolated from cultures of both blood and ascites fluid. The second patient, a 70-year-old Chinese man, presented with right lower lobar pneumonia complicated with empyema and septic shock. Blood cultures grew B. pseudomallei. Both patients had underlying diabetes mellitus; one also had liver cirrhosis and chronic renal failure, while the other had a renal stone. The first patient died of refractory septic shock prior to diagnosis. The second patient survived with the use of intravenous ceftazidime for 30 days, followed by oral amoxicillin-clavulanic acid for a further 3 months. These cases serve as a reminder to clinical physicians that melioidosis is now no longer exclusive to patients with a history of travel to endemic areas. A high index of clinical suspicion is required for early diagnosis and treatment in order to reduce the mortality and improve clinical outcome.

Melioidosis, an infectious disease that affects many mammals, was first identified in Burma by Whitmore in 1912. It is caused by Burkholderia pseudomallei, a gram negative bacillus of the Pseudomonas family, which is found in soil and water. Long present in Southeast Asia and numerous tropical areas, melioidosis has recently appeared in temperate zones including mainland France. The incidence in endemic areas is between 6% and 20% of the population and short period of exposure is sufficient to be contaminated. In man the contamination occurs mainly through skin wounds and the disease can be clinically inapparent. Diabetes, renal disease, and various forms of immunodepression are triggering factors for the onset of a variety of symptoms ranging from acute septicemia to abscesses involving almost any organ in the body. Ceftazidime alone or a combination of clavulanate and amoxicilline is the treatment of choice but the mortality rate in patients with acute forms is still 40% and relapse can occur if treatment is stopped too soon. Bacteriologic and serologic tests can fail and awareness of a history of geographic exposure is an important diagnostic criteria for this disease which has been expanded with the growth of international travel.

Melioidosis is an important infectious disease of southeast Asia caused by an intracellular bacterium, Burkholderia pseudomallei. Cellular immunity is postulated to play important roles in immunity to melioidosis that may influence the severity and clinical outcome of the disease. The present study was undertaken to investigate possible associations of melioidosis with HLA class II alleles. HLA typing of HLA-DRB1, -DQA1, and -DQB1 was performed using polymerase chain reaction and sequence-specific oligonucleotide hybridization (PCR-SSO). Seventy-nine melioidosis patients and 105 healthy, ethnically and geographically matched controls were studied. Among 24 DRB1 alleles, 7 DQA1 alleles, and 13 DQB1 alleles identified in this population, an association with melioidosis was observed with DRB1*1602 which was increased in melioidosis patients (10.1%) compared to normal controls (4.8%), p = 0.047 (odds ratio (OR) = 2.25). In addition, significant increase of DRB1*1602 allele frequency and decrease of DQA1*03 were also observed in septicemic melioidosis patients, the most severe form of the disease (p = 0.01, OR = 3.10; and p = 0.047, respectively). Furthermore, a trend of association of DRB1*0701, DQA1*0201, and DQB1*0201 with relapse cases of melioidosis was also noted. In contrast, no HLA association was observed in localized melioidosis or melioidosis with diabetes mellitus. These findings provide the suggestive evidence of an immunogenetic basis of certain aspects of melioidosis.

During the period 1989 to 1996, a total of 372 cases of melioidosis, with 147 deaths, were reported, giving a mean annual incidence rate of 1.7 per 100,000 population and a case-fatality rate of 39.5%. Majority (89%) of the clinical cases were confirmed by culture of Burkholderia pseudomallei, while the others were presumptive cases based on a single blood specimen with an indirect haemaglutination (IHA) antibody titre of > or = 1:16. The highest incidence rate was reported in those aged 45 years and above (5.7 per 100,000 population), males (2.8 per 100,000 population), and Indian ethnic group (3.0 per 100,000 population). Cases were distributed throughout the island all year round. There was no correlation with rainfall. Most of the cases (77.4%) had other concurrent medical conditions, the most common being diabetes mellitus (57.5%). Factors significantly associated with a higher case-fatality rate were age (55 years and above), septicaemia, smoking history and heart or renal failure. The overall case-fatality rate has been declining from 60% in 1989 to 27% in 1996 due to a greater awareness among medical practitioners to diagnose and treat the disease early. The overall seroprevalence of IHA antibody (titre of > or = 1:16) among asymptomatic population groups was 0.2%. B. pseudomallei isolated from clinical specimens were sensitive to imipenem (100%), ceftazidime (99.1%), piperacillin (99.7%), ampicillin-clavulanate (98.5%), minocycline (97.4%), chloramphenicol (94.3%), doxycycline (94.3%) and tetracycline (93.9%). Of 395 samples of soil collected during epidemiological investigation of reported cases, 1.8% were positive for B. pseudomallei.

Melioidosis is most frequently encountered in pulmonary localization. Melioidosis is an infectious disease caused by Burkholderia pseudomallei first described by Whitmore in 1912 in Burma. B. pseudomallei is a Gram negative rod belonging to the Pseudomonadaceae family. Soil and water are the natural reservoirs for the germ which is a specific pathogen for several mammal species. Long endemic in Southeast Asia and several tropical zones, B. pseudomallei has recently been found in temperate zones, including France. Human contamination occurs via the transcutaneous route and often leads to dormant inapparent infection. Many conditions, such as diabetes, renal lithiasis, various circumstances of immunodepression or stress, facilitate clinical manifestations which vary greatly. Pulmonary manifestations may be acute and extensive, producing a torpid pseudo-tuberculous condition or a variety of clinical and radiological features mimicking other diseases. Bacteriological and serological tests may be negative. Exposure in an endemic zone, the notion of a favorable context, weight loss, cavitary images on successive chest x-rays and the presence of extra-pulmonary localizations may be suggestive. Ceftazidime or the amoxicillin-clavulanic acid combination are indicated, but mortality in acute forms still reaches 40%. Relapse can be expected if the treatment duration is too short.

Melioidosis is a rare but potentially fatal infectious disease in Taiwan, although it has been endemic in Southeast Asia, especially northeast Thailand, and northern Australia. In this article, we report a male diabetes with fulminant pneumonia, and septicemia caused by Burkholderia pseudomallei without traveling abroad before this episode. Productive cough and intermittent chills, high fever for one week, followed by progressively deteriorating dyspnea, shock, disturbed consciousness status were the major presentations. Blood culture grew B. pseudomallei on the fifth admission day. Unfortunately, the patient died on the 9th admission day, despite intensive care and the broad-spectrum antimicrobial regimen used.

Melioidosis is a protean disease caused by Burkholderia pseudomallei. It is rare in the UK and is generally only seen in patients with a travel history to endemic areas such as Thailand, Singapore and Malaysia. Cases may present with disseminated bacteraemic, non-disseminated bacteraemic, multi-focal bacteraemic or localized disease. Subclinical infections also occur. Following acquisition of the organism a patient may remain asymptomatic for several years before infection becomes clinically apparent. Factors such as diabetes, renal failure or other causes for a decrease in host immunity may precipitate the appearance of overt disease. The current treatment choice for severe melioidosis is parenteral ceftazidime followed by oral amoxycillin-clavulanic acid or a combination of co-trimoxazole, doxycycline and chloramphenicol. We report a case of melioidosis in a 59-year-old male diabetic from Bangladesh who initially responded to piperacillin-tazobactam but was changed to ceftazidime when a definitive diagnosis was made. His condition deteriorated on the latter antibiotic. He subsequently responded to imipenem. The patient's long-term outcome is still not known.

A case-control study was conducted in four hospitals in northeastern Thailand to identify risk factors for melioidosis and bacteremic melioidosis. Cases were patients with culture-proven melioidosis, and there were two types of controls (those with infections, i.e., with community-acquired septicemia caused by other bacteria, and those without infection, i.e., randomly selected patients admitted with noninfectious diseases to the same hospitals). Demographic data, clinical presentations, and suspected risk factors were analyzed. Diabetes mellitus, preexisting renal diseases, thalassemia, and occupational exposure, classified by the soil and water risk assessment, were confirmed to be significant risk factors for melioidosis and bacteremic melioidosis. Only diabetes mellitus was a significant factor associated with bacteremic melioidosis, as compared with nonbacteremia. A significant interaction was found between diabetes mellitus and occupational exposure. Thus, diabetic rice farmers would be the most appropriate population group for targeted control measures such as vaccination in the future.

Melioidosis is a tropical environmental hazard that causes acute and chronic pulmonary disease, abscesses of the skin and internal organs, meningitis, brain abscess and cerebritis, and acute fulminant rapidly fatal sepsis. It is more common among adults, individuals with diabetes, and individuals with chronic renal disease, but it can occur in normal hosts and children. Burkholderia pseudomellei is the most prevalent cause of community-acquired pneumonia, liver and splenic abscess, and sepsis in northeastern Thailand. Melioidosis can reactivate years after primary infection and result in chronic or acute life-threatening disease. With increasing worldwide travel and migration, patients may present in nonendemic countries with reactivation melioidosis decades after leaving an endemic region. We discuss seven selected patients presenting with this disease to a tertiary care facility in Bangkok between 1995 and 1997. Awareness should allow early diagnosis and treatment, which can lead to decreased morbidity and mortality.
