    Orlistat is a widely used drug in treating obesity as it promotes weight reduction. The aim of this study was to determine the protective effects of orlistat (10 mg/kg/day) on cardiovascular parameters and oxidative stress biomarkers in high-fat diet (HFD)-induced obese rats. Methods:Twenty-four male rats Sprague Dawley rats were divided into three groups and fed with normal diet (N), HFD and HFD with orlistat (HFD+O). Orlistat was administered daily by oral gavage and after six weeks, all rats were sacrificed. Results:Administration of orlistat along with HFD (HFD+O) has brought significant decreases in Lee obesity index and LDL level compared to HFD group. Activities of cardiac superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) were significantly higher, whereas level of oxidised LDL was significantly lower in HFD+O group compared to HFD group. HFD group had significantly higher necrotic patch area in myocardium while minimal histological changes were seen in HFD+O group. Conclusion:This study may suggest that administration of orlistat at 10 mg/kg/day for 6 weeks may have protective effects against the changes on Lee obesity index, lipid profiles, cardiac oxidative stress biomarkers and histology of myocardium in HFD-induced obese rats possibly through its hypolipidaemic and antioxidant actions.

    Cavitary lung lesions of various etiologies may be encountered in patients with respiratory symptoms associated with fever. Non-malignant cavitary lesions may mimic malignant lung lesions on most of radiographic modalities including chest radiographs or thoracic computed tomography (CT). Primary lung malignancy can be detected in as high as one-fifths of CT thorax as cavitary lesions and the remaining aetiologies may be due to bacterial, parasitic, and invasive fungal infections, as well as Granulomatosis with polyangiitis (GPA), sarcoidosis, septic thrombo-embolism, and lung metastasis from extra-pulmonary primaries. We report an interesting case of melioidosis infection complicated with pulmonary embolism, both of which can lead to cavitary lung lesions and subsequently cause a clinical conundrum.

    We report a case of 28-year-old Malay woman who initially presented with multiple joints pain with underlying poorly controlled asthma since her childhood. She was treated as seronegative arthritis. However, the involvement of joints, asthma and high-eosinophil counts raised suspicion of Churg-Strauss syndrome. This disease is undoubtedly rare in Malaysians or even in Asian populations. After appropriate therapy was delivered for the correct diagnosis her clinical condition improved. She is currently receiving maintenance treatment.

    This article aims to report a case of a young female patient with anti-neutrophil cytoplasmic antibodies-associated vasculitis complicated with pulmonary renal syndrome, multiple relapses, and who later developed venous thromboembolism. Pulmonary renal syndrome is a well- recognized and lethal complication; however, incidence of venous thromboembolism has not been well-described. In this article, we described a 38-year-old Malay female patient admitted in 2008 with three-month history of peripheral neuropathy of lower limbs and right ankle ulcers. Initial inflammatory markers were high and perinuclear Anti-Neutrophil Cytoplasmic Antibodies were positive. She was diagnosed as anti-neutrophil cytoplasmic antibodies-associated vasculitis and started on intravenous methylprednisolone with methotrexate. She presented with relapse of skin vasculitis complicated with pulmonary renal syndrome after being stable for one year. She was intubated and proceeded with plasmapheresis and hemodialysis. She completed six cycles of cyclophosphamide. Renal biopsy revealed chronic changes consistent with end stage renal disease. She further relapsed in 2011 with nasal blockage, epistaxis, and nasal deviation. Chest X-ray revealed lung nodules. Prednisolone was increased, her symptoms settled, and she was discharged with azathioprine. She was readmitted at the end of the same year due to two-day history of right deep vein thrombosis and she later succumbed to methicillin-resistant Staphylococcus aureus sepsis.

    A 47-year-old Malay man who presented with fever, poor oral intake and loss of weight for 1 month duration. Further work-up revealed evidence of disseminated Salmonella infection that was further complicated with pericardial and pleural empyema. Cultures from pericardial and pleural fluids grew Salmonella species with negative serial blood cultures. Contrast enhanced CT thorax showed pleural effusion with large pericardial effusion. The patient was treated with antibiotics and drainage of pericardial and pleural empyema was done and he was discharged well.

    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.

    We report a case of a 46-year-old Malay woman with underlying hypothyroidism post thyroidectomy who presented with worsening breathlessness, orthopnoea, productive cough and left-sided pleuritic chest pain of 3 days duration. Chest X-ray on admission showed left-sided massive hydropneumothorax. Pleural tapping revealed empyema. A chest tube was inserted immediately. The culture of pleural fluid grew Streptococcus constellatus The patient was treated with antibiotics for a total of 6 weeks and underwent open thoracotomy and decortication during admission. Subsequently, her lung condition improved and there was no evidence of recurrence during follow-up.

    A previously healthy 20-year-old man presented with prolonged intermittent low grade fever and cough for 6months. He had bilateral calf pain and lower limb weakness 2days prior to admission. Physical examination revealed multiple enlarged lymph nodes with hepatomegaly. There was bilateral calf tenderness with evidence of proximal myopathy. Full blood picture showed lymphocytosis with reactive lymphocytes and eosinophilia. Creatine kinase and lactate dehydrogenase were markedly elevated. Over 2 weeks of admission, patient was treated symptomatically until the muscle biopsy of right calf revealed eosinophilic myositis with muscular sarcocystosis. He was treated with albendazole and high-dose corticosteroids. Symptoms subsided on reviewed at 2weeks and the dose of corticosteroid was tapered down slowly over a month. Due to poor compliance, he was readmitted 1month later because of relapsed. High-dose corticosteroid was restarted and duration for albendazole was prolonged for 1month. His symptom finally resolved over 2weeks.

    We report a case of severe Plasmodium knowlesi and dengue coinfection in a previously healthy 59-year-old Malay man who presented with worsening shortness of breath, high-grade fever with chills and rigors, dry cough, myalgia, arthralgia, chest discomfort and poor appetite of 1 week duration. There was a history mosquito fogging around his neighbourhood in his hometown. Further history revealed that he went to a forest in Jeli (northern part of Kelantan) 3 weeks prior to the event. Initially he was treated as severe dengue with plasma leakage complicated with type 1 respiratory failure as evidenced by positive serum NS1-antigen and thrombocytopenia. Blood for malarial parasite (BFMP) was sent for test as there was suspicion of malaria due to persistent thrombocytopenia despite recovering from dengue infection and the presence of a risk factor. The test revealed high count of malaria parasite. Confirmatory PCR identified the parasite to be Plasmodium knowlesi Intravenous artesunate was administered to the patient immediately after acquiring the BFMP result. Severe malaria was complicated with acute kidney injury and septicaemic shock. Fortunately the patient made full recovery and was discharged from the ward after 2 weeks of hospitalisation.

    A previously healthy 80-year-old woman presented with a history of a thorn prick injury over the
    distal phalange of her left finger obtained while gardening two months ago. She claimed to have a
    non-healing cut with a nodular lesion, which progressively increased in size, extending upwards
    towards the region of her left arm. There was no fever or palpable lymph nodes in the axillary region.
    She had been prescribed antibiotics from the local hospital but her condition did not improve.

    We present an interesting case of late-onset intracranial bleeding (ICB) as a complication of Streptococcus gordonii causing infective endocarditis. A previously healthy young woman was diagnosed with infective endocarditis. While she was already on treatment for 2 weeks, she had developed seizures with a localising neurological sign. An urgent non-contrasted CT brain showed massive left frontoparietal intraparenchymal bleeding. Although CT angiogram showed no evidence of active bleeding or contrast blush, massive ICB secondary to vascular complication of infective endocarditis was very likely. An urgent decompressive craniectomy with clot evacuation was done immediately to release the mass effect. She completed total 6 weeks of antibiotics and had postoperative uneventful hospital stay despite having a permanent global aphasia as a sequel of the ICB.

    We report a case of Raynaud's phenomenon in a patient with psoriatic arthritis (PsA). A middle-aged right-handed housewife presented with complaints of severely painful hand discolouration for 1 week, which usually worsened with cold exposure. She was diagnosed with PsA 6 months earlier. Her PsA was well controlled with weekly methotrexate. Physical examination showed no features of scleroderma or skin necrosis of her right hand. Both radial pulses were strong and symmetrical. Her nailfolds were visibly normal. The extractable nuclear antigen panel and other blood investigations were negative for scleroderma and other possible causes of secondary Raynaud's phenomenon. Occupational or environmental factors were also excluded. Dermatoscope examination of the nailfolds revealed some areas of dilated capillary loops, areas of vascular sparing and proximal nail fold telangiectasia. The diagnosis of secondary Raynaud's phenomenon was made, and an oral calcium channel blocker was started. The patient had significant improvement in symptoms shortly afterwards.

    Vanishing lung syndrome (VLS) is a rare condition characterized by giant emphysematous bullae. It is frequently misdiagnosed as pneumothorax. We describe a case of a 30-year-old male who presented with shortness of breath, reduced effort tolerance, and pleuritic chest pain for three months. He was initially diagnosed with bilateral pneumothorax based on clinical examination and chest radiograph findings. However, further imaging with a high resolution computed tomography (HRCT) of the thorax confirmed bilateral giant emphysematous bullae. Our patient subsequently underwent video-assisted thoracoscopic surgery (VATS) and bullectomy. In this report, we discuss the clinical presentations, radiological features, and the management of VLS. We also highlight the differentiating features of VLS from a pneumothorax.

    Obesity and hyperlipidemia are major risk factors for developing vascular diseases. Bee bread (BB) has been reported to exhibit some biological actions, including anti-obesity and anti-hyperlipidemic. This study aims to investigate whether bee bread can ameliorate vascular inflammation and impaired vasorelaxation activity through eNOS/NO/cGMP pathway in obese rats. Forty male Sprague-Dawley rats were randomly divided into four groups (n = 10/group), namely: control (normal group), obese rats (OB group), obese rats treated with bee bread (0.5 g/kg/day, OB/BB group) and obese rats treated with orlistat (10 mg/kg/day, OB/OR group). The latter three groups were given a high-fat diet (HFD) for 6 weeks to induced obesity before being administered with their respective treatments for another 6 weeks. After 12 weeks of the total experimental period, rats in the OB group demonstrated significantly higher Lee obesity index, lipid profile (total cholesterol, triglyceride, low-density lipoprotein), aortic proinflammatory markers (tumor necrosis factor-α, nuclear factor-κβ), aortic structural damage and impairment in vasorelaxation response to acetylcholine (ACh). Bee bread significantly ameliorated the obesity-induced vascular damage manifested by improvements in the lipid profile, aortic inflammatory markers, and the impaired vasorelaxation activity by significantly enhancing nitric oxide release, promoting endothelial nitric oxide synthase (eNOS) and cyclic guanosine monophosphate (cGMP) immunoexpression. These findings suggest that the administration of bee bread ameliorates the impaired vasorelaxation response to ACh by improving eNOS/NO/cGMP-signaling pathway in obese rats, suggesting its vascular therapeutic role.

    Background: Gouty arthritis is a disease of global burden in which defective metabolism of uric acid causes arthritis. Gouty arthritis or medications used for its treatment may lead to uric acid-associated complications such as upper gastrointestinal bleeding (UGIB) and renal impairment.

    Methods: In this cross-sectional study with retrospective record review, 403 established gouty arthritis patients were recruited to determine the incidence of UGIB and associated factors among gout patients who were on regular nonsteroidal anti-inflammatory drugs (NSAIDs).

    Results: The mean age of the 403 gouty arthritis patients was 55.7 years old and the majority (n = 359/403; 89.1%) were male. The incidence of UGIB among gouty arthritis patients who were on NSAIDs was 7.2% (n = 29/403). Older age (p < 0.001), diclofenac medication (p = 0.003), pantoprazole medication (p = 0.003), end-stage renal failure (ESRF) (p = 0.007), smoking (p = 0.035), hypertension (p = 0.042) and creatinine (p = 0.045) were significant risk factors for UGIB among the gouty arthritis patients in univariable analysis. Older age (p = 0.001) and diclofenac medication (p < 0.001) remained significant risk factors for UGIB among the gouty arthritis patients in multivariable analysis.

    Conclusions: Age and diclofenac were significantly associated with UGIB among patients with gouty arthritis on regular NSAIDs, indicating that these factors increased the risks of developing UGIB in gout patients. Hence, these high-risk groups of gouty arthritis patients should be routinely monitored to avoid the potential onset of UGIB. Our data also suggest that diclofenac should be prescribed for the shortest duration possible to minimize the risk of developing UGIB in gout patients.

    Rheumatoid Arthritis (RA) is a chronic inflammatory polyarthritis disease predominantly involving synovial tissue of the joints and characterized by destructive and debilitating arthritis (Choy et al., 2012; Weyand, 2000; reviewed by Worthington, 2005; Gabriel et al., 1999). It can cause progressive and irreversible destruction of tendons, cartilage and bone, which leads to lack of ability to perform daily activities (Singh et al., 2015). Although the aetiology of RA remains unsolved, the strength of the genetic component in RA is estimated based on familial aggregation and information about epidemiology and population prevalence (reviewed by Gregersen, 1999, Choy et al., 2012). (Copied from article).

    The receptors for IL-35, IL-12Rβ2 and gp130, have been implicated in the inflammatory pathophysiology of autoimmune diseases. In this study, we set out to investigate the serum IL-35 levels and the surface levels of IL-12Rβ2 and gp130 in CD3+CD4+, CD3+CD4─ and CD3─CD4─ lymphocyte subpopulations in systemic lupus erythematosus (SLE) patients (n=50) versus healthy controls (n=50). The potential T cell subsets associated with gp130 transcript (i.e. IL6ST) expression in CD4+ T cells of SLE patients was also examined in publicly-available gene expression profiling (GEP) datasets. Here, we report that serum IL-35 levels were significantly higher in SLE patients than healthy controls (p=0.038) but it was not associated with SLEDAI-2K scores. The proportions of IL-12Rβ2+ and gp130+ cells in SLE patients did not differ significantly with those of healthy controls in all lymphocyte subpopulations investigated. Essentially, higher SLEDAI-2K scores were positively correlated with increased proportion of gp130+ cells, but not IL-12Rβ2+ cells, on CD3+CD4+ T cells (r=0.425, p=0.002, q=0.016). Gene Set Enrichment Analysis (GSEA) of a GEP dataset of CD4+ T cells isolated from SLE patients (n=8; GSE4588) showed that IL6ST expression was positively associated with genes upregulated in CD4+ T cells vs myeloid or B cells (q<0.001). In an independent GEP dataset of CD4+ T cells isolated from SLE patients (n=9; GSE1057), IL6ST expression was induced upon anti-CD3 stimulation, and that Treg, TCM and CCR7+ T cells gene sets were significantly enriched (q<0.05) by genes highly correlated with IL6ST expression (n=92 genes; r>0.75 with IL6ST expression) upon anti-CD3 stimulation in these SLE patients. In conclusion, gp130 signaling in CD3+CD4+ T cell subsets may contribute to increased disease activity in SLE patients, and it represents a promising therapeutic target for inhibition in the disease.
