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.

Fulltext Systemic lupus erythematosus and melioidosis

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.

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.

Fulltext Honeycomb and necklace signs in liver abscesses secondary to melioidosis

Melioidosis is endemic in Southeast Asia and tropical Australia with varying clinical features from benign skin lesions to fatal septicaemia. Imaging plays an important role in evaluation of the melioid liver abscesses. A 45-year-old man with underlying diabetes presented with fever and lethargy for 2 weeks and abdominal pain for 2 days. His liver was enlarged on examination. Blood investigations revealed mild leucocytosis and raised liver enzymes. Ultrasound showed multiple multiloculated hypoechoic lesions throughout the liver and spleen. CT of abdomen confirmed that some liver lesions were made up of asymmetric locules of varying sizes (honeycomb sign), while others had hypodense centre with small symmetric peripheral locules in radial fashion (necklace sign). Blood culture was positive for Burkholderia pseudomallei He was subsequently treated with ceftazidime for a month followed by oral trimethoprim-sulfamethoxazole for 3 months. Follow-up CT of abdomen a month after diagnosis and treatment showed resolving hepatic and splenic lesions.

Clinical characteristics and outcomes of bacteraemic melioidosis in a teaching hospital in a northeastern state of Malaysia: a five-year review

PMID: 20818090

BACKGROUND: Melioidosis is an important public health problem causing community acquired sepsis in the northeastern part of Malaysia.
METHODOLOGY: From January 2001 to December 2005, we reviewed case reports of all bacteraemic melioidosis admitted to a tertiary teaching hospital, Hospital Universiti Sains Malaysia.
RESULTS: Thirty-five patients had positive blood culture for meliodosis and 27 case reports were traceable for further analysis. The mean age was 46.8 + 20.0 years. Twenty patients (74.1%) were male. The main clinical presentation was fever that occurred in 23 (85.2%) patients. Eighteen patients (66.7%) had lung involvement and three patients had liver abscess. Two patients presented with scrotal swelling, one of whom further developed Fournier's Gangrene. Nineteen (70.4%) patients had underlying diabetes, five of whom were newly diagnosed during the admission. Thirteen (48.1%) patients were treated with high-dose ceftazidime and six (22.2%) patients were treated with imipenem. Eight (29.6%) patients were not given anti-melioidosis therapy because the causative agents were not identified until after the patients died. The patients were admitted 16.8 days + 18.1. Seventeen patients (63.0%) died in this series, 13 patients of whom died within four days of admission.
CONCLUSIONS: The wide range of clinical presentations and the fatal outcomes of melioidosis require a high level of suspicion among physicians to develop an early appropriate therapy and reduce the mortality rate.

Fulltext Genome wide transcriptome profiling of a murine acute melioidosis model reveals new insights into how Burkholderia pseudomallei overcomes host innate immunity

At present, very little is known about how Burkholderia pseudomallei (B. pseudomallei) interacts with its host to elicit melioidosis symptoms. We established a murine acute-phase melioidosis model and used DNA microarray technology to investigate the global host/pathogen interaction. We compared the transcriptome of infected liver and spleen with uninfected tissues over an infection period of 42 hr to identify genes whose expression is altered in response to an acute infection.
