Budesonide/Formoterol (Symbicort) combination therapy as both maintenance and reliever treatment (SMART) is a novel approach in asthma management. We examined its 'real-life effectiveness' in treating Malaysian patients with moderate-to-severe asthma in whom despite on combined inhaled corticosteroids and long-acting beta2-agonist, were still inadequately controlled. In a retrospective study, 22 eligible adult patients on SMART [mean (range) age: 49 (36-65) years; FEV1: 41 (21-74)% predicted] were identified from medical records of an urban-based university hospital chest clinic, and their clinical outcomes studied at three months. Another 16 patients [50 (14-66) years; 48 (20-91)% predicted] of similar severity and treatment (i.e. Symbicort maintenance treatment plus short-acting beta2-agonist as reliever), but not on SMART, were used as comparator over the same assessment period. In addition, the patients were separately interviewed with standard questionnaire on their satisfaction and compliance to the SMART approach. In SMART group, rescue treatment requirement (p<0.001) and FEV1 [median difference = 2.5%, p=0.015; mean difference: 90 ml, p=0.013] showed significant improvement while in comparator, there was significant improvement only in the requirement for rescue treatment (p=0.023). Hospital admission rates were significantly reduced in SMART group compared to the other (p=0.039), but not in emergency treatment. Five patients asked to discontinue SMART while all others were satisfied, compliant and perceived improvement of their asthma with SMART. The maximum daily doses of inhaled budesonide and formoterol were 1400 microg and 31.5 microg respectively. Our preliminary findings suggest that SMART approach can be attempted as an effective and safe treatment option for patients with inadequately controlled moderate-to-severe asthma in Malaysian setting.

The simian parasite Plasmodium knowlesi causes severe human malaria; the optimal treatment remains unknown. We describe the clinical features, disease spectrum, and response to antimalarial chemotherapy, including artemether-lumefantrine and artesunate, in patients with P. knowlesi malaria diagnosed by PCR during December 2007-November 2009 at a tertiary care hospital in Sabah, Malaysia. Fifty-six patients had PCR-confirmed P. knowlesi monoinfection and clinical records available for review. Twenty-two (39%) had severe malaria; of these, 6 (27%) died. Thirteen (59%) had respiratory distress; 12 (55%), acute renal failure; and 12, shock. None experienced coma. Patients with uncomplicated disease received chloroquine, quinine, or artemether-lumefantrine, and those with severe disease received intravenous quinine or artesunate. Parasite clearance times were 1-2 days shorter with either artemether-lumefantrine or artesunate treatment. P. knowlesi is a major cause of severe and fatal malaria in Sabah. Artemisinin derivatives rapidly clear parasitemia and are efficacious in treating uncomplicated and severe knowlesi malaria.
