Cardiomyopathy following COVID-19 vaccination in a patient with systemic lupus erythematosus.

There are an increasing number of reports of myocarditis associated with mRNA-based COVID-19 vaccination. We describe the case of a female patient with underlying systemic lupus erythematosus, who developed heart failure symptoms following a second dose of the BNT162b2 vaccine. Despite her history of refractory systemic lupus erythematosus, the disease remained stable after she began rituximab treatment. She underwent serial transthoracic echocardiogram and cardiac magnetic resonance imaging for the evaluation of cardiomyopathy. She showed improvement in cardiac function after treatment with glucocorticoids and intravenous immunoglobulin therapy.

Multifocal osteoarticular tuberculosis in a systemic lupus erythematosus (SLE) patient: a rarity or an underdiagnosed condition?

Tuberculosis (TB) and its association with rheumatic diseases have been widely recognised. Occurrence of multifocal skeletal involvement constitutes <5% of all skeletal TB cases. We present a Malay patient with multifocal osteoarticular TB (OATB). A 35 year-old SLE woman with background usage of corticosteroid therapy and Azathioprine presented with lupus nephritis flare. Renal biopsy revealed diffuse proliferative lupus nephritis and intravenous (IV) Cyclophosphamide 0.5 g/m2 (850 mg) was initiated. One week later, patient complained dorsum of left hand and right knee swelling. On physical examination, patient was afebrile and the left hand swelling was cystic in consistency while right knee was warm and tender. Erythrocyte Sedimentation Rate (ESR) was 50 mm/hr and C-Reactive Protein (CRP) was 9.4 mg/L. Her Mantoux test was positive with 20 mm induration. Wrist radiograph and chest radiograph was normal. Musculoskeletal ultrasound showed 4th extensor compartment tenosynovitis with Doppler signal and right knee effusion with synovial proliferation. Extensor tenosynovectomy and right knee aspiration was performed. Left hand excised tissue and right knee synovial fluid for acid-fast bacilli (AFB) stain, TB PCR, bacterial and fungal cultures were negative. Urgent histopathological examination of the excised tissue showed necrotising granulomatous inflammation. Patient was empirically started on TB treatment and subsequent mycobacterial culture confirmed the diagnosis of TB. The joints swelling resolved after one month of TB treatment. Multifocal OATB is an infrequent form of extrapulmonary TB and diagnosing OATB requires high index of suspicion particularly in SLE patient on immunosuppression. Prompt investigations are essential to the diagnosis of this rare condition for early initiation of anti-tuberculous therapy.

Pulmonary manifestation as initial presentation for systemic lupus erythematosus.

We report a 29-year-old Malay man who had pulmonary manifestations as an initial presentation for systemic lupus erythematosus. He had prolonged hospitalization and was treated with intensive care therapy with immunosuppressants.

Takayasu Arteritis in Major Rheumatology Centers in Malaysia.

OBJECTIVE: There is paucity of data for Takayasu arteritis (TAK) among South Asians. We aimed to evaluate the clinical features, angiographic findings, as well as treatment and outcome of TAK among Malaysian multiethnic groups. METHODS: This is a retrospective review of 40 patients with TAK seen in major rheumatology centres in Malaysia between April 2006 and September 2013. RESULTS: Majority were female patients (92.5%), with a female-to-male ratio of 12:1. Median duration of disease from diagnosis was 66 months (interquartile range, 33-177 months). Fifteen (37.5%) were Malays, 9 (22.5%) each were Indians and indigenous from East Malaysia and 7 (17.5%) were Chinese. Indian and indigenous from East Malaysia were overrepresented in this disease. The mean (SD) age of symptom onset and diagnosis were 25.5 (8.1) and 27.4 (8.4), respectively. The 3 most common clinical presentations at diagnosis were diminished or absent pulse, which occurred in 80% of the patients, followed by blood pressure discrepancy (60%) and arterial bruit (52.5%). There was no difference in clinical presentation among ethnic groups. The subclavian artery was the commonest vessel involved (72.5%), followed by the carotid artery (65%) and renal artery (47.5%). Eight patients had coronary artery involvement, and 2 patients had pulmonary artery involvement. Type I arterial involvement was the commonest (80.0%), followed by type IV (35%), present in isolation or mixed type. Glucocorticoid was the main medical treatment (90.0%). Nineteen patients (47.5%) underwent revascularization procedures. Five patients died during the follow-up period. CONCLUSIONS: The Malaysian TAK cohort had similarities with and differences from other published TAK cohort. A nationwide TAK registry is needed to determine the prevalence of the disease among different ethnic groups.

Rituximab for refractory digital infarcts and ulcers in systemic sclerosis.

Systemic sclerosis is an uncommon connective tissue disease characterised by excessive deposition of collagen and vasculopathy which affects the skin and multiple internal organs. It is associated with autoimmunity, inflammation, vasculopathy and fibrosis. Managing Raynaud's phenonemon, digital infarcts and ulcers in systemic sclerosis patients is often a challenge particularly among rheumatologists. We report a case of systemic sclerosis patient with refractory digital infarcts and ulcers responded successfully with rituximab.
