Melioidosis is an infectious disease that is initiated by a bacteria recognized as Burkholderia pseudomallei. Despite the high fatality rate from melioidosis, there is a minimal published study about the disease in Malaysia.This study aimed to identify the prognostic factors of mortality among melioidosis patients in northern Malaysia.All inpatient patients who were admitted to Hospital Sultanah Bahiyah, Kedah and Hospital Tuanku Fauziah, Perlis with culture-confirmed melioidosis during the period 2014 to 2017 were included in the study. The study retrospectively collected 510 melioidosis patients from the Melioidosis Registry. Hazard ratio (HR) used in advanced multiple Cox regression was used to obtain the final model of prognostic factors of melioidosis. The analysis was performed using STATA/SE 14.0 for Windows software.From the results, among the admitted patients, 50.1% died at the hospital. The mean age for those who died was 55 years old, and they were mostly male. The most common underlying disease was diabetes mellitus (69.8%), followed by hypertension (32.7%). The majority of cases (86.8%) were bacteremic. The final Cox model identified 5 prognostic factors of mortality among melioidosis patients. The factors were diabetes mellitus, type of melioidosis, platelet count, white blood cell count, and urea value. The results showed that bacteremic melioidosis increased the risk of dying by 3.47 (HR: 3.47, 95% confidence intervals [CI]: 1.67-7.23, P = .001) compared to non-bacteremic melioidosis. Based on the blood investigations, the adjusted HRs from the final model showed that all 3 blood investigations were included as the prognostic factors for the disease (low platelet: HR = 1.76, 95% CI: 1.22-2.54, P = .003; high white blood cell: HR = 1.49, 95% CI 1.06-2.11, P = .023; high urea: HR = 2.92, 95% CI: 1.76-4.85, P

Melioidosis is an important cause of community-acquired infection in Southeast Asia and northern Australia. Studies from endemic countries have demonstrated differences in the epidemiology and clinical features among children diagnosed with melioidosis. This suggests that local data are needed to determine the risk factors and outcome in specific areas.

We reported a case of a young female patient presented with sepsis and diagnosed with melioidosis and systemic lupus erythematosus (SLE) within the same admission. She presented with 1-week history of productive cough, progressive dyspnoea together with prolonged fever, arthralgia, rashes and oral ulcers. She had septicemic shock, respiratory failure requiring intubation and ventilation in intensive care unit and subsequently developed acute renal failure requiring haemodialysis. Antibiotics and immunosuppressive treatment including low-dose intravenous cyclophosphamide were commenced. She had a remarkable recovery and was discharged after 6 weeks. There was no evidence of active SLE or relapse of melioidosis during clinic follow-ups.

Septicaemic melioidosis: a review of 50 cases from Malaysia

Puthucheary SD, Parasakthi N, Lee MK

Trans R Soc Trop Med Hyg, 1992 11 1;86(6):683-5.

PMID: 1287945

Fifty cases of septicaemic melioidosis were reviewed. There was a preponderance of disease among males (male:female ratio 3.2:1) and those aged over 30 years. The presenting clinical features were very varied and not pathognomonic, ranging from fever, cough and septicaemia to fulminant septicaemia and shock. Pulmonary involvement was recorded in 58% of the patients. Skin and soft tissue sepsis was seen in 24%, but many had signs and symptoms of multiorgan involvement. Associated underlying illness was identified in 76% of patients, diabetes mellitus being the commonest (38%), while 34% had more than one predisposing factor. The mortality of 65% in our series is a reflection of the less than satisfactory status of the diagnosis and therapy of septicaemic melioidosis. Only 24% of our patients received appropriate empirical antibiotic therapy. A high index of suspicion of melioidosis in endemic areas and the use of appropriate empirical antimicrobial therapy would be a step towards reducing the high mortality rate.

Fulltext Relapse of chronic melioidosis in a paediatric cystic fibrosis patient: first case report from Malaysia

Mariappan V, Thavagnanam S, Vellasamy KM, Teh CJS, Atiya N, Ponnampalavanar S, et al.

BMC Infect Dis, 2018 Sep 05;18(1):455.

PMID: 30185168 DOI: 10.1186/s12879-018-3371-7

BACKGROUND: Burkholderia pseudomallei is the causative agent of melioidosis, which is a potentially life threatening disease endemic in Southeast Asian countries. In Malaysia, cystic fibrosis (CF) is an uncommon condition. The association between CF and B.pseudomallei infections has been reported previously. However, this is the first case report of a pediatric melioidosis relapse and co-infection with other Gram-negative bacteria in Malaysia.

CASE PRESENTATION: A 14-year-old Chinese Malaysian boy presented with a history of recurrent pneumonia, poor growth and steatorrhoea since childhood, and was diagnosed with CF. B. pseudomallei was cultured from his sputum during three different admissions between 2013 and 2016. However, the patient succumbed to end stage of respiratory failure in 2017 despite antibiotics treatment against B.pseudomallei. The isolates were compared using multilocus-sequence typing and repetitive-element polymerase chain reaction (PCR), and confirmed that two of the isolates were of same sequence type, which may indicate relapse.

CONCLUSIONS: CF patients should be aware of melioidosis in endemic regions, as it is an emerging infectious disease, especially when persistent or recurrent respiratory symptoms and signs of infection occur. The high prevalence rates of melioidosis in Malaysia warrants better management options to improve quality of life, and life expectancy in patients with CF. Travel activities to endemic regions should also be given more consideration, as this would be crucial to identify and initiate appropriate empiric treatment.

Potential of repurposing chloroquine as an adjunct therapy for melioidosis based on a murine model of Burkholderia pseudomallei infection

Ganesan N, Embi N, Hasidah MS

Trop Biomed, 2020 Jun 01;37(2):303-317.

PMID: 33612800

Burkholderia pseudomallei is the etiologic agent of melioidosis, a major cause of community-acquired pneumonia and sepsis in the endemic areas. The overall mortality of patients with severe melioidosis remains high due to severe sepsis attributed to overwhelming inflammatory cytokine response in spite of recommended antibiotic therapy. It is crucial that therapeutic approaches beyond just effective antibiotic treatment such as adjunct therapy be considered to mitigate the dysregulated inflammatory signaling and augment host defenses. In an acute B. pseudomallei infection model, we have previously demonstrated that treatment with anti-malarial drug, chloroquine, modulated inflammatory cytokine levels and increased animal survivability via Akt-mediated inhibition of glycogen synthase kinase-3β (GSK3β). GSK3β is a downstream effector molecule within the phosphatidylinositol 3-kinase (PI3K)/ Akt axis which plays a pivotal role in regulating the production of pro- and anti-inflammatory cytokines. Here we evaluate the effect of chloroquine treatment in combination with a subtherapeutic dose of the antibiotic doxycycline on animal survivability, cytokine levels and phosphorylation states of GSK3β (Ser9) in a murine model of acute melioidosis infection to investigate whether chloroquine could be used as an adjunct therapy along with doxycycline for the treatment of melioidosis. Our findings revealed that 50 mg/kg b.w. chloroquine treatment together with a dose of 20 mg/kg b.w. doxycycline improved survivability (100%) of mice infected with 3 X LD50 of B. pseudomallei and significantly (P<0.05) lowered the bacterial loads in spleen, liver and blood compared to controls. B. pseudomallei-infected mice subjected to adjunct treatment with chloroquine and doxycycline significantly (P<0.05) reduced serum levels of pro-inflammatory cytokines (TNF-α, IFN-γ and IL-6) but increased levels of antiinflammatory cytokines (IL-4 and IL-10). Western blot analysis demonstrated that the intensities of pGSK3β (Ser9) in liver samples from mice treated with chloroquine and doxycycline combination were significantly (P<0.05) higher suggesting that the adjunct treatment resulted in significant inhibition of GSK3β. Taken together the bacteriostatic action of doxycycline coupled with the cytokine-modulating effect of chloroquine gave full protection to B. pseudomallei-infected mice and involved inhibition of GSK3β. Findings from the present study using B. pseudomallei-infected BALB/c mice suggest that chloroquine is a plausible candidate for repurposing as adjunct therapy to treat acute B. pseudomallei infection.

Fulltext Melioidotic septic arthritis: a case report and literature review

Raja NS

J Microbiol Immunol Infect, 2007 Apr;40(2):178-82.

PMID: 17446969

Burkholderia pseudomallei, the causative agent of melioidosis, is endemic in southeast Asia and northern Australia. In recent years, the incidence of melioidosis has increased worldwide. Septic arthritis is a rare but well-recognized manifestation of melioidosis. Patients with underlying medical conditions, such as diabetes mellitus, renal impairment, cirrhosis, and malignancy are at greater risk. The presentations of melioidotic septic arthritis often mimic other disease processes and patients may not always be clinically septic. We present a case of septic arthritis due to B. pseudomallei in a 66-year-old male with diabetes mellitus presenting with a history of fever and ankle swelling. Follow-up ankle X-ray showed soft tissue swelling. Synovial fluid and blood samples grew B. pseudomallei. The patient improved gradually after parenteral administration of ceftazidime (2 g 8-hourly) and cotrimoxazole (1440 mg 8-hourly). He was discharged on oral cotrimoxazole (1440 mg 12-hourly), doxycycline (100 mg 12-hourly), and chloramphenicol (500 mg 6-hourly) for 6 months. This case highlights the possible occurrence of melioidotic septic arthritis, and the importance of prompt initiation of appropriate antimicrobials to achieve good outcomes.

PMID: 19421682

Melioidosis is caused by Burkholderia pseudomallei, a Gram-negative bacillus. Melioidosis can affect many organs, including the prostate. However, prostatic abscess due to melioidosis is uncommon. We describe five cases of melioidosis with prostatic abscess. Four of five patients had diabetes mellitus and had more than one organ involvement. The diagnosis of prostatic abscess in our patients was only made with computed tomography of the abdomen and pelvis. None of our patients underwent surgical drainage and all remained well after treatment with antibiotics, except for one mortality secondary to severe septicaemia.

Ng WM, Kwan MK, Merican AM

Singapore Med J, 2006 Jan;47(1):71-4.

PMID: 16397726

Melioidosis is caused by an infection by Burkholderia pseudomallei. Osteomyelitis is a recognised manifestation of melioidosis but Burkholderia pseudomallei is a relatively rare aetiological agent in musculoskeletal infections. We report a 32-year-old diabetic man with septicaemia due to melioidotic infection of the spleen, liver and distal femur. The osteomyelitis relapsed despite being treated with the standard radical debridement and insertion of gentamycinimpregnated polymethylmetacrylate (PMMA) beads, followed by an optimal antibiotic therapy. The PMMA-gentamycin beads were then removed. The bone defect was debrided and packed with calcium hydroxyapatite blocks filled with ceftazidime powder. The osteomyelitis was successfully treated and the patient remained free of infection four years postoperatively. Computed tomography demonstrated successful incorporation of the calcium hydroxyapatite into host bone.

Fulltext Melioidosis: misdiagnosed in Nepal

Shrestha N, Adhikari M, Pant V, Baral S, Shrestha A, Basnyat B, et al.

BMC Infect Dis, 2019 Feb 19;19(1):176.

PMID: 30782129 DOI: 10.1186/s12879-019-3793-x

BACKGROUND: Melioidosis is a life-threatening infectious disease that is caused by gram negative bacteria Burkholderia pseudomallei. This bacteria occurs as an environmental saprophyte typically in endemic regions of south-east Asia and northern Australia. Therefore, patients with melioidosis are at high risk of being misdiagnosed and/or under-diagnosed in South Asia.

CASE PRESENTATION: Here, we report two cases of melioidosis from Nepal. Both of them were diabetic male who presented themselves with fever, multiple abscesses and developed sepsis. They were treated with multiple antimicrobial agents including antitubercular drugs before being correctly diagnosed as melioidosis. Consistent with this, both patients were farmer by occupation and also reported travelling to Malaysia in the past. The diagnosis was made consequent to the isolation of B. pseudomallei from pus samples. Accordingly, they were managed with intravenous meropenem followed by oral doxycycline and cotrimoxazole.

CONCLUSION: The case reports raise serious concern over the existing unawareness of melioidosis in Nepal. Both of the cases were left undiagnosed for a long time. Therefore, clinicians need to keep a high index of suspicion while encountering similar cases. Especially diabetic-farmers who present with fever and sepsis and do not respond to antibiotics easily may turn out to be yet another case of melioidosis. Ascertaining the travel history and occupational history is of utmost significance. In addition, the microbiologist should be trained to correctly identify B. pseudomallei as it is often confused for other Burkholderia species. The organism responds only to specific antibiotics; therefore, correct and timely diagnosis becomes crucial for better outcomes.

PMID: 725999 DOI: 10.1016/0035-9203(78)90175-X

Previous reports of melioidosis in Sabah are reviewed and a detailed account of a case, presenting as prostatitis, in a 40-year-old British male is given. The history suggested that the organism, Pseudomonas pseudomallei, was transmitted by a fly which entered the eye. Diagnosis was delayed and treatment presented some difficulty, the organism being relatively insensitive to amplicillin and gentamicin. Co-trimoxazole was the most effective, followed by minocycline. Cure was eventually achieved and after four years the patient was fit and normal, except for sterility.

Melioidosis is an infectious disease caused by Burkholderia pseudomallei whose clinical diagnosis can be difficult due not only to its varied clinical presentation but also to the difficulties in the microbiological diagnosis.Thus, it may be necessary to use molecular techniques for its proper identification once it is suspected.
There are few antibiotics available for the treatment of this disease, which must be used over a long period of time. Although it is known to be endemic in Thailand, Malaysia, Singapore, Vietnam, and Australia, in Colombia there are few reported cases.
We describe a case of melioidosis in the northern region of Colombia. Additionally, we review its clinical characteristics and treatment and we describe the local epidemiology of this disease.

PMID: 16234087

Bacterial arteritis is relatively uncommon and management of this condition, which carries high morbidity and mortality, is difficult and time-consuming. Common organisms implicated include Salmonella and Staphylococcus. Arteritis as a result of infection by Burkholderia pseudomallei (formerly Pseudomonas pseudomallei) has been rarely reported in the English literature. This organism, which is endemic in our part of the world, is well known to cause a wide spectrum of septic conditions. A review of cases managed at Hospital Kuala Lumpur revealed that bacterial arteritis due to melioidosis is not such a rare entity. We share our experience in the management of this condition using three cases as examples.
