ABSTRACT
Background: Disseminated infections such as tuberculosis are known to result in a systemic inflammatory response leading to thrombosis, with increasing reported cases of thrombotic event being observed in patients infected with covid-19. This is the first reported case on co-infection with COVID-19 pneumonia and disseminated tuberculosis causing catastrophic antiphospholipid syndrome (CAPS). Method(s): The report highlighted the challenges in the diagnosis and management which include the use of corticosteroid in setting of systemic infections. Another diagnostic dilemma was to explain the cause of myositis by tuberculous or autoimmune. Case Presentation: We report a 26-year- old man with HbE trait thalassemia who reported unintentional weight loss, night sweats for 1 month prior to the diagnosis of covid-19 infection on 10th March 2022. Seven days later, he was hospitalized for suspected perforated appendix. Computed tomography (CT) abdomen revealed hepatosplenomegaly, prostatitis, seminal vesiculitis. Multiple matted abdominal lymph nodes were not amenable for biopsy. Soon, he appeared toxic, dyspneic required non-invasive ventilation with bilateral parotitis. He had raised erythrocyte sedimentation (ESR) 52 mm/hour, C-reactive protein (CRP) 221 mg/dl, lactate dehydrogenase (LDH) 730U/L. Direct Coomb's antibody was positive but did not have any form of haemolysis. Complement 3 (0.45 g/L) and complement 4 (0.1 g/L) levels were low. Serum IgG4, procalcitonin, anti-nuclear antibody, cultures and virology were negative. Sputum for acid fast bacilli (AFB) was positive on Auramine O stain but the Ziehl-Nelson (ZN) stain and tuberculous PCR (GeneXpert) were negative. Diagnosis of disseminated tuberculosis was made but his abdominal pain persisted despite being on anti-tuberculous therapy (ATT), and he had new evidence of splenic infarct. CT angiogram also revealed celiac trunk and superior mesenteric artery thrombosis. Antiphospholipid (aPL) test was positive for lupus anticoagulant, beta 2 glycoprotein 1 and anti-cardiolipin antibodies. Therapeutic anticoagulation and plasma exchange were initiated for probable CAPS followed by intravenous immunoglobulin and corticosteroid. Thereafter, the patient developed severe bilateral pelvic girdle pain with evidence of myositis on the MRI (Figure 2). Serum creatine kinase was never elevated. Anti-PL- 7 and anti Ro-52 were borderline elevated. He recovered well and ambulant before discharged home. Conclusion(s): Our case highlight the complexicity of presentation of CAPS who manifested as multiple arterial thrombosis. The diagnosis of disseminated tuberculosis relied strongly on microbiological, imaging and clinical presentation as histopathological evidence was not feasible. Management challenges were deciding on corticosteroid in disseminated infection and the need for confirmation of persistent positive aPL test and to monitor myositis symptom to help guide decision making.

ABSTRACT
Background: COVID-19 pandemic has been devastating not only medically but also socially and economically. Selangor, an urbanised state in Malaysia, has been severely affected by COVID19. There is concern that patients with rheumatic diseases (RD) may have higher risk of infection, with increased mortality1. Objectives: To investigate patients' characteristics which are associated with 'feeling stressed' among patients with RD during the second wave of COVID19 infection in Selangor. Methods: This is a cross-sectional study conducted over 3 weeks during the second wave of COVID19 infection in Malaysia. Patients with RD, scheduled for rheumatology clinic appointment in a rheumatology referral centre were invited to participate in this study. Personal and clinical data were collected by phone interview and from patients' medical records respectively. Patients were asked to grade their disease activity by giving a score from 0 (not active) to 10 (active). All patients were asked 'are you feeling stressed' and the answer was recorded as yes or no. Reasons explored for a yes answer, included financial, social disruption, physical illness and future uncertainties. Categorical and continuous data were analysed using chi-squared test and student t-test, respectively. A p-value of <0.05 is considered statistically significant. Results: Three hundred and sixty-one patients with various RD participated in this study. The mean age of these was 48.2 years (range between 16-80 years). More than half (54.3%) were Malay and other ethnicities were Chinese (25.5%), Indian (18.2%) and others (2%). A quarter of patients (24.7%) were not working (unemployed, retired and students) and a third of patients (32.1%) had unpaid work (mainly housewife). The other patients' characteristics are shown in Table 1. Eighty-three (23%) admitted to 'feeling stressed' and the stressors identified were physical illness in 34 (40.9%), social disruption in 23 (27.7%), financial problems in 23 (27.7%) and future uncertainties in 19 (22.9%). Patients' characteristics that were significantly different between patients who were 'feeling stressed' and not 'feeling stressed' were age, employment status and perceived disease activity (Table 1). Conclusion: The COVID19 pandemic has caused mental distress in a significant number of RD patients and associations were found with older age, having paid work and perceived disease activity. Issues that may influence patients' responses, including access to rheumatology care, medication and fear of getting infection were not explored in this study.
