Key Findings There is some short-term benefit from the use of mesenchymal stem cell therapy for severe COVID-19 in a lowquality, small randomized controlled trial (RCT). Further studies, ideally with good quality RCTs, are needed to confirm benefit and safety. • Mesenchymal stem cells (MSCs) are non-hematopoietic adult stem cells that are able to self-renew and differentiate into various cells of any cell lineage. MSCs have the ability to migrate (homing) to damaged tissue for repair and regeneration, as well as signal other cells to help in tissue repair. It can effect cellular differentiation, consequently shifting the immune system from Th1 to Th2 responses.1,2 • A recent review showed improved disease-associated parameters in experimental acute respiratory distress syndrome (ARDS).3 • We found three studies (one case report, one prospective cohort, and one small randomized controlled trial) reporting the effects of MSC on COVID-19. Based on low-quality evidence, it appeared that human umbilical cord blood-derived MSC, given after failure to improve with standard treatment, had beneficial effects in terms of earlier onset of clinical improvement among individuals with severe or critical COVID-19. However, 28-day clinical improvement and mortality were not significantly different compared to standard treatment. There was no reported adverse reaction. • There are 52 registered and ongoing clinical trials to investigate the efficacy and safety of mesenchymal stem cells as treatment for COVID-19. • Mesenchymal stem cell therapy is not included in any of the existing guidelines for the treatment of COVID-19.

Key Findings Among patients with confirmed COVID-19 infection and hypertension, there is insufficient evidence that RAS antagonists are associated with mortality or severe COVID-19 disease. • There is uncertainty with regards to the safe use of renin-angiotensin system (RAS) antagonists, such as angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB), for COVID-19 patients with hypertension and other comorbidities (heart failure, chronic kidney disease) because of two possible contradictory mechanisms 1) upregulation of ACE2 receptors that may facilitate the virus entry into the lung. and 2) control of unabated angiotensin II levels reducing acute lung injury. • Based on very low-quality retrospective cohort studies, there is insufficient evidence that RAS antagonists are associated with increased mortality (6 studies) or severe disease (10 studies) among patients with confirmed COVID-19 infection and hypertension. • There are 36 ongoing studies (21 RCTs, 1 single-arm trial, 4 prospective cohorts, 4 retrospective cohorts, 4 casecontrol, and 2 cross-sectional) on this topic. • The European Society of Cardiology (ESC) Council on Hypertension, the International Society of Hypertension (ISH) and the joint statement by the American College of Cardiology (ACC), American Heart Association (AHA), and Heart Failure Society of America (HFSA) all caution against discontinuing RAS-related treatments in patients with hypertension who become infected with COVID-19.

Objectives: Recent studies show that patients with young-onset gout present with visible tophi or nephrolithiasis on diagnosis. In the Philippines, where gout is prevalent, there is no published work on this subset of patients. This study presents the clinical characteristics of a cohort of Filipino patients with gout whose symptoms started at 30 years of age or younger. Methods: The case records of all patients who fulfilled the 1977 American College of Rheumatology (ACR) criteria for gout seen in four adult rheumatology services were reviewed. We selected those whose age of onset of gout was at 30 years or younger. The demographic characteristics, medical history, laboratory parameters, and presenting manifestations were described. Results: Six hundred sixty-nine records of patients with gout were reviewed; 101 (15%) fulfilled the young-onset gout criteria. The mean age of onset was 25±4.40 years (range 14-30), and the mean disease duration before diagnosis was 12.64±11.91 years. All of the patients were male and most were married; 76% were alcoholic beverage drinkers and 38% were smokers. A family history of gout was noted in 47%. Most patients (66%) were already on nonsteroidal anti-inflammatory drugs (NSAIDs), 24% on colchicine, and 14% on urate-lowering therapy before consult at the rheumatology clinic. By history, at onset, the most common pattern of joint involvement was monoarthritis (95%), affecting the ankles (60%), knees (52%), and 1st metatarsophalangeal (MTP) joint (51%). However, on the first rheumatology clinic visit, 34% of arthritis was polyarticular, more than 68% had more than three arthritis attacks per year, and there were tophi in 35%. The mean duration before visible tophi formation was 2.81±6.75 years. Around 21% had nephrolithiasis or a history thereof. The mean serum uric acid (SUA) was 9.18 mg/dL and the mean serum creatinine was 1.5 mg/dL. Thirty-seven percent had estimated glomerular filtration rate (GFR) <60 mL/min. Conclusion Young-onset gout was present in 15% of our patients and gout was familial in 47%. There was a delay in diagnosis of as long as ten years in most of the patients. On presentation at the rheumatology clinic, more than 34% had polyarticular arthritis, 35% had tophi, and 37% had low estimated GFR. This emphasizes the importance of awareness and prompt diagnosis to ensure correct treatment and prevention of complications

Introduction: Cognitive impairment (CI) in patients with systemic lupus erythematosus (SLE) presents with or without overt signs of central nervous involvement. The prevalence of CI is variable, ranging from 19-80%. It is often overlooked, leading to high healthcare costs and productivity loss. The usual tools for detection are expensive, time-consuming and not locally available. Detection of CI using the Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Test (MoCA) is more clinically relevant and practical. The objectives of this study are to determine the prevalence of CI in SLE patients using MMSE/MoCA, to determine the degree of impairment in the different cognitive domains, and to characterize patients with CI in terms of disease activity, education, and employment. Methods: This is a cross-sectional study of 62 SLE patients, 19 years or older, at a rheumatology clinic. Demographic and disease characteristics were collected. The validated Filipino versions of the MMSE/MoCA test were administered. Descriptive and non-parametric statistics were applied. Results: Most patients are female (96.77%), below collegiate level of education (58.06%), and unemployed (70.97%). Mean disease duration is 8.92 (SD±7.03) years. Mean age at diagnosis is 28 (SD±10.30) years. Hypertension is the most common co-morbidity. Most have low lupus disease activity or are in remission (80.65%). Most are on prednisone (72.58%), with an average dose of 11.88mg/day (SD±10.66). The prevalence of CI is 38.71% (MMSE-P) and 77.42% (MoCA-P). The presence of CI is not related to educational level, employment, and disease activity. Conclusion Cognitive impairment (CI) is common in this cohort of SLE patients. Disease activity, level of education and employment do not seem to affect its occurrence. The MMSE-P and MoCA-P are rapid tools to assess the presence of CI and should be used in clinical practice to improve the quality of care for patients with lupus.
