INTRODUCTION

Takayasu arteritis (TA) is a rare chronic large vessel vasculitis that affects the aorta and its major branches with a median age of onset of 25 years. The disease has a worldwide incidence of 1-2 per million, primarily affecting females with a 9:1 ratio. It is considered as an autoimmune disease that leads to progressive vessel thickening and stenosis, or aneurysmal dilatation. Coronary artery involvement is observed in 5.9%-58.2% of TA cases. We present a case of TA in a Filipino male presenting concurrently with myocardial infarction (MI) and ischemic stroke.

CASE REPORT

A 41-year-old Filipino male smoker with hypertension presented with chest pain, left-sided paresthesia and hemiparesis. Initial assessment revealed differential blood pressure between the arms, sensory and motor deficits, and abnormal ABI. Electrocardiogram confirmed anteroseptal ST-elevation MI and cranial computed tomography (CT) showed ischemic stroke. Arterial duplex scan had findings suggestive of hemodynamically significant lower extremity stenosis. A CT aortogram revealed multiple occlusions, including in the left subclavian artery, suggesting TA. Coronary angiography was attempted but was deferred due to peripheral arterial occlusion. A CT coronary angiogram revealed severe stenosis of the left anterior descending artery and moderate stenosis of the other coronaries. The patient was treated with dual antiplatelet therapy, statins, anticoagulation, corticosteroids and methotrexate. He experienced significant improvement in neurological symptoms and was chest pain-free upon discharge. At the 1-month follow-up, the patient remained asymptomatic.

DISCUSSION

Coronary involvement in TA can manifest as angina, MI, or other coronary lesions. The coexistence of MI and ischemic stroke in the same event is rare. Traditional risk factors for ischemic heart disease (IHD) in this patient such as hypertension and smoking may have contributed to the presentation, though TA itself is known to accelerate atherosclerosis. Limited vascular access hindered coronary intervention in this case and revascularization strategies remain challenging in active TA. The formation of extensive collateral arteries, along with early initiation of immunosuppressive therapy, likely contributed to the patient’s survival.

CONCLUSION

This case illustrates a rare and complex case of TA in a male patient with concurrent MI and ischemic stroke. Although coronary revascularization was not pursued due to occluded access, immunosuppressive therapy successfully managed the patient’s condition. Extensive collateral artery formation and early therapeutic intervention were key factors in the patient’s favorable outcome.

Background and Objectives: Pruritus is a common and disabling symptom affecting as much as 50-90% of chronic kidney disease (CKD) patients undergoing dialysis. The pruritus experienced by these patients is often resistant to common anti-pruritic agents and has an overall negative impact on quality of life. With its antioxidant property and anti-inflammatory effects, omega-3 fatty acids have been used to alleviate pruritus. The objective of this study is to assess the effect of omega-3 fatty acid supplementation in reducing the severity of pruritus among dialytic CKD patients. Methods: Various electronic databases were searched from inception to August 2022. Randomized controlled trials comparing the effect of omega-3 fatty acids versus placebo on the pruritus scores were included. The studies were independently assessed by three reviewers. Revman version 5.4 was used to analyze the data extracted from the studies while heterogeneity was evaluated using Chi2 and I2. Results: A total of four studies with a population of 166 patients were included in the meta-analysis. The results show an overall beneficial effect of omega-3 fatty acids with a standardized mean difference of -1.40 (CI -1.74 to -1.05, Z=7.95, p value <0.00001). With a Chi2 of 2.91 (p=0.41) and I2 of 0%, there was no significant heterogeneity observed in the pooled analysis. Conclusion Overall, the results of the meta-analysis support the finding that omega-3 fatty acid supplementation may have a beneficial effect on reducing the severity of pruritus among CKD patients on dialysis.

Background and Objectives: The immediate post-discharge period of COVID-19 patients is a vulnerable state due to several complications that may arise during this time. Some patients get readmitted shortly after being discharged while others report persistence of symptoms, develop specialized needs, or observe a decline from their baseline functional capacity. Information on the outcomes of post-COVID discharge patients in our institution is currently lacking. This study described the outcomes of patients with COVID-19 after their discharge from the service areas of Philippine General Hospital. Methods: This study is a retrospective chart review involving charts of all adult patients discharged from the PGH COVID service areas last August 2021 to October 2021. Data from their follow up consults at 1 week, 1 month, and 3 months post-discharge were reviewed. Baseline characteristics and post-discharge outcomes including post-COVID symptoms, special care needs, mortality, rehospitalization, emergency consult, level of dependence, and ability to return to work were assessed. Results: A total of 171 patient charts were included. The mean age of patients was 53.7 years. Most were male (60.2%), unemployed (59.7%), non-smoker (55%), hypertensive (57.9%), diabetic (50.2%), and obese (50.2%). Most of them were oxygen requiring (80%) and with severe to critical COVID infection (72.5%) during admission. At 3 months post-discharge, 113 (66%) were stable and able to complete the follow up, 8 (4.6%) died, 9 (5.2%) got readmitted, and 41 (23.9%) were lost to follow up. Among those who were able to follow up after 3 months, 84 (74%) were asymptomatic. Among those who remained symptomatic, the most common symptoms were dyspnea, fatigue, and cough. After 3 months, 100 (88%) did not require special care needs, 100 (88%) were fully independent, and 45 (39.8%) were able to return to baseline work. Conclusions Despite the majority of patients having severe to critical COVID infection during admission, most were asymptomatic within 3 months post-discharge. In those who developed persistent symptoms, dyspnea, cough, and fatigue were the most common symptoms identified regardless of COVID severity. Majority did not require special care needs.

Objectives: Adherence to clinical practice guidelines (CPG) has been shown to reduce inter-physician practice variation and improve quality of care. This study evaluated guideline adherence of physicians in two tertiary public hospitals to local CPG on COVID-19. Methods: This was a multicenter, retrospective chart review, rapid assessment method study. Guideline adherence and non-adherence (overuse and underuse) to 15 strong recommendations in the prevailing Philippine COVID-19 Living Recommendations were assessed among a sample of patients admitted in two centers from July to October 2021. Differences in adherence across COVID-19 disease severities and managing hospital units were analyzed. Results: A total of 723 patient charts from two centers were reviewed. Guideline adherence to dexamethasone use among patients with hypoxemia is 91.4% (95% CI 88.6 to 93.6) with 9.2% overuse. Tocilizumab was underused in 52.2% of patients with indications to receive the drug. There was overuse of empiric antibiotics in 43.6% of patients without suspicion of bacterial coinfection. Lowest adherence to antibiotic use was seen among patients with critical disease severity and those managed in the intensive care unit. None of the other non-recommended treatment modalities were given. Conclusion Management of COVID-19 in both centers was generally adherent to guideline recommendations. We detected high underuse of tocilizumab probably related to the global supply shortage during the study period and high overuse of antibiotics in patients without suspicion of bacterial coinfection. While the results of this study cannot be generalized in other healthcare settings, we recommend the application of similar rapid assessment studies in guideline adherence evaluation as a quality improvement tool and to identify issues with resource utilization especially during public health emergencies.
