ABSTRACT

OBJECTIVE: To establish the scanning protocol for 2-dimensional shear wave elastography (SWE) on normal entheses by investigating the possible confounding factors that may increase the variability of measured elasticity. MATERIAL AND METHODS: 30 normal quadriceps entheses were scanned using SWE to compare the stiffness and coefficient variation by changing the ultrasonic coupling gel thickness, knee position, region of interest size, and scanning plane. RESULTS: No significant difference in median shear wave velocity (SWV) was observed in different coupling gel thicknesses. The median SWV was higher in the knee flexion position than in the extended position (p < 0.001). Increased knee flexion led to stiffer quadriceps enthesis and higher SWV (ρ = 0.8, p < 0.001). The median SWV was higher when the diameter region of interest was 4.0 mm than 2.0 mm (p = 0.001). The median SWV was higher in the transverse plane than in the longitudinal plane (p < 0.001). Strong correlation was found between SWV and the degree of the shear wave to muscle fiber direction (ρ = 0.8, p < 0.001). The coefficient variation was lower in a gel thickness of 2.5 cm, with an extended knee, a region of interest of 2.0 mm, and a longitudinal plane (p > 0.05). For interobserver reliability for the proposed protocol, the intraclass correlation coefficients was 0.763. CONCLUSION: In this study, we determined supine position with the knee extended; using 2.0 mm diameter region of interest and image acquisition at the longitudinal plane with thicker layer coupling gel seems most appropriate to reliably image healthy quadriceps entheses with SWE.

ABSTRACT

Objectives: Gout is a treatable disease. A complication of untreated or poorly-controlled gout is tophi formation. We conducted this study to investigate the associated factors of tophaceous gout among patients who attended 20 primary care clinics in Selangor, an urbanized state in Malaysia. Methods: We conducted a cross-sectional study from July to October 2019 that included all patients with gout who attended the clinics. Data on clinical demographics and laboratory results were collected. Comparison between tophaceous and non-tophaceous groups was performed using descriptive analysis. Results: A total of 421 patients with gout were involved in this study, 83 (19.7%) patients had visible tophi and were categorized into the tophaceous group, while the other 338 (80.3%) patients were categorized into the non-tophaceous group. The majority of patients were male with a mean age of 57.6±12.8 years. Three factors found to be significantly associated with tophaceous gout were age at symptom onset [tophaceous (45.6±13.3 years) vs. non-tophaceous (49.7±13.9 years), p = 0.026], mean disease duration of gout [tophaceous (105.2±92.6 months) vs. non-tophaceous (77.6±88.6 months), p = 0.013], and baseline serum uric acid level [tophaceous (622.3±129.1 µmol/L) vs. non-tophaceous (582.6±102.3 µmol/L), p = 0.021]. Conclusions: Tophaceous gout is associated with longer disease duration, higher baseline serum uric acid level, and younger age at symptoms onset. Hence, early initiation of urate-lowering therapy with a treat-to-target approach is crucial to prevent tophi formation.

ABSTRACT

Objectives: Although the risk of diabetes mellitus has been recognised in rheumatoid arthritis, undiagnosed dysglycaemia remained under-reported. The study aimed to determine the prevalence and associated factors of dysglycaemia among patients with rheumatoid arthritis, utilising the oral glucose tolerance test. Methods: This cross-sectional study involved patients with rheumatoid arthritis, aged ⩾30 years. Following an oral glucose tolerance test, they were divided into two: dysglycaemia and normoglycaemia. Demographic and laboratory parameters were compared using logistic regression analyses. Results: There were 35.5% (55/155) patients with dysglycaemia (including 25.8% impaired glucose tolerance, 7.1% diabetes mellitus and 1.9% with both impaired fasting glucose and impaired glucose tolerance). Patients with dysglycaemia were heavier (65.5 ± 12.3 versus 60.7 ± 10.6 kg, p = 0.01), had wider waist (89.0 ± 12.5 versus 83.1 ± 9.6 cm, p < 0.01), lower high-density lipoprotein cholesterol (1.4 ± 0.3 versus 1.5 ± 0.4 mmol/L, p = 0.02), higher triglyceride (1.3 (0.9-1.8) versus 0.9 (0.8-1.2) mmol/L, p < 0.01) and intercellular adhesion molecule-1 (361.79 (290.38-481.84) versus 315.92 (251.45-407.93) ng/mL, p = 0.01). History of smoking (odds ratio: 5.70, confidence interval: 1.27-25.7), elevated triglyceride (odds ratio: 2.87, confidence interval: 1.33-6.22) and intercellular adhesion molecule-1 (odds ratio: 1.003, confidence interval: 1.001-1.006) were significantly associated with dysglycaemia. Conclusions: Prevalence of undiagnosed dysglycaemia, particularly impaired glucose tolerance, was high in these patients with rheumatoid arthritis, using a 75-g oral glucose tolerance test, which was not associated with disease activity or corticosteroid use. Those with high triglyceride, history of smoking and elevated intercellular adhesion molecule-1 were the two significant predictors for dysglycaemia in our patients with rheumatoid arthritis. Oral glucose tolerance test could be an important laboratory investigation for dysglycaemia in these high-risk patients.

ABSTRACT

OBJECTIVES: The Coronavirus Disease 2019 (COVID-19) outbreak is a global pandemic and has caught the attention of the rheumatology fraternity, where patients are thought to be at higher risk of infection. We aimed to study the incidence of COVID-19 infection and depression and anxiety symptoms among patients with rheumatic disease (RD) in Hospital Selayang, Malaysia, during the COVID-19 pandemic. METHODS: A cross-sectional study was conducted via phone interview using a structured questionnaire in patients with RD aged > 18 years old scheduled for clinic appointments from 4 to 28 May 2020, which coincided with the second wave of COVID-19 cases in Malaysia. The questionnaire included demographics, COVID-19 screening questions, depression and anxiety symptoms screening using questions derived from the Patient Health Questionnaire-2 (PHQ-2) and Generalized Anxiety Disorder-2 (GAD-2). RESULTS: Among the 361 patients enrolled, the majority were females (83.1%), and over half (54.3%) were ethnic Malays, 41.6% had rheumatoid arthritis, 34.6% had systemic lupus erythematosus, 12.2% had spondyloarthropathy, and only one (0.3%) patient had COVID-19 infection. The mean age of patients was 48.2 years (range: 16-80 years). The frequency of patients with depression and anxiety symptoms was 8.6% and 6.9%, respectively. Married patients reported feeling more anxious (p =0.013), while patients with tertiary education levels reported feeling more depressed (p =0.012). CONCLUSIONS: The incidence of COVID-19 infection is low, probably due to the low rate of testing. Depression and anxiety symptoms reported by patients in our cohort were modest. Our findings suggest that the COVID-19 pandemic has a greater impact on married patients with RD and those with a higher education level.

ABSTRACT

BACKGROUND: The 2013 Malaysian Clinical Practice Guidelines on the Management of Osteoarthritis (OA) recommend a linear step-up approach to manage knee OA. However, patients with knee OA often require a multimodal approach to address OA-related pain symptoms and functional limitations. This consensus aimed to provide doctors with an updated set of evidence-based, clinical experience-guided recommendations to manage knee OA. METHODS: A multi-speciality expert panel consisting of nine Malaysian physicians from different healthcare settings who manage a diverse OA patient population was convened. Using a combination of the ADAPTE process and modified Delphi method, the panel reviewed current evidence on the management of knee OA and synthesised a set of nine recommendations on the management of knee OA, supported by an algorithm that summarises the consensus' core messages. RESULTS: A multimodal intervention strategy is the mainstay of OA management and the choice of any single or multimodal intervention may vary over the course of the disease. Overall, a non-pharmacological core treatment set of patient education, weight loss and exercise is recommended for all patients. When pharmacotherapy is indicated, symptomatic slow-acting drugs for osteoarthritis are recommended at the early stage of disease, and they can be paired with physical therapy as background treatment. Concurrent advanced pharmacotherapy that includes non-steroidal anti-inflammatory drugs, intraarticular injections and short-term weak opioids can be considered if patients do not respond sufficiently to background treatment. Patients with severe symptomatic knee OA should be considered for knee replacement surgery. Management should begin with specific treatments with the least systemic exposure or toxicity, and the choice of treatment should be determined as a shared decision between patients and their team of healthcare providers. CONCLUSIONS: This consensus presents nine recommendations that advocate an algorithmic approach in the management of patients living with knee OA. They are applicable to patients receiving treatment from primary to tertiary care providers in Malaysia as well as other countries.

ABSTRACT

Lymphocytic interstitial pneumonia (LIP) is a rare condition, commonly associated with Sjogren's syndrome (SS). We report a 53-year-old woman with an incidental finding of an abnormal chest radiograph. LIP was diagnosed based on high-resolution computed tomography and lung biopsy, but treatment was not initiated. Six years later, she developed cough and dyspnoea, associated with dry eyes, dry mouth, and arthralgia. While being investigated for the respiratory symptoms, she developed cutaneous vasculitis and was treated with 1 mg/kg prednisolone, which resulted in the improvement of her respiratory symptoms. Physical examination revealed fine bibasal crepitations, active vasculitic skin lesions, and a positive Schirmer's test. Investigations revealed a restrictive pattern in the pulmonary function test, stable LIP pattern in HRCT, and positive anti-Ro antibodies. She was treated with prednisolone and azathioprine for 18 months, and within this time, she was hospitalised for flare of LIP, as well as respiratory tract infection on three occasions. During the third flare, when she also developed cutaneous vasculitis, she agreed for prednisolone but refused other second-line agents. To date, she remained well with the maintenance of prednisolone 2.5 mg monotherapy for more than one year. The lessons from this case are (i) patients with LIP can be asymptomatic, (ii) LIP can precede symptoms of SS, and (iii) treatment decision for asymptomatic patients with abnormal imaging or patients with mild severity should be weighed between the risk of immunosuppression and risk of active disease.

ABSTRACT

Cysts are a common finding of lymphocytic interstitial pneumonia (LIP) on imaging. Usually, they are limited in number and size. Tiny and numerous cysts of peribronchovascular distribution are less typical but a recognized appearance in LIP.

ABSTRACT

Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae with predominant involvement of skin and nerves. We present a 70-year-old man with leprosy whose initial presentation resembled rheumatologic disease, due to leprae reaction. He presented with an 8-week history of worsening neuropathic pain in the right forearm, associated with necrotic skin lesions on his fingers that had ulcerated. Physical examination revealed two tender necrotic ulcers at the tip of the right middle finger and the dorsal aspect of the left middle finger. The patient had right wrist tenosynovitis and right elbow bursitis. Apart from raised inflammatory markers, the investigations for infection, connective tissue disease, vasculitis, thromboembolic disease and malignancy were negative. During the fourth week of hospitalization, we noticed a 2-cm hypoesthetic indurated plaque on the right inner arm. Further examination revealed thickened bilateral ulnar, radial and popliteal nerves. A slit skin smear was negative. Two skin biopsies and a biopsy of the olecranon bursa revealed granulomatous inflammation. He was diagnosed with paucibacillary leprosy with neuritis. He responded well to multidrug therapy and prednisolone; his symptoms resolved over a few weeks. This case illustrates the challenges in diagnosing a case of leprosy with atypical presentation in a non-endemic country.
