ABSTRACT
Introduction: The coronavirus disease 2019 (COVID-19) infection has changed everyday clinical practice, with a shortage of solid data about its implications for ST-elevation myocardial infarction (STEMI) patients. Aim: To evaluate the impact of COVID-19 on 6-month clinical outcomes of patients with STEMI and determine the mortality predictors after STEMI during the COVID-19 pandemic. Material and methods: This prospective observational study was conducted on consecutive STEMI patients who presented to our hospital between April and October 2021. A total of 74 COVID-19-positive patients were included in group I and compared to 148 COVID-19-negative patients (group II). We compared the two cohorts' rates of major adverse cardiovascular events (MACEs; composite of death from any cause, recurrent MI, target-vessel revascularization, and stroke) at 6 months. Results: COVID-19 STEMI patients were more likely to present with angina equivalent symptoms, had higher Killip class at admission, and higher levels of high-sensitive cardiac troponin T and serum C-reactive protein. The 6-month rates of MACEs were significantly higher in STEMI patients with COVID-19 compared to non-COVID-19 patients (41.9% vs. 16.9%, respectively; p < 0.001) and were mainly due to higher in-hospital mortality (20.3% vs. 6.1%, respectively; p = 0.001). The independent predictors of 6-month mortality in STEMI patients during the COVID-19 pandemic were the absence of ST resolution, low systolic blood and higher Killip class on admission, presence of severe MR and atrial fibrillation, and anterior wall STEMI. Conclusions: STEMI patients with superimposed COVID-19 infection had worse clinical outcomes, with almost three times higher in-hospital mortality and 6-month MACEs.
ABSTRACT
Type 2 diabetes mellitus (T2DM) is a potential risk factor for the development of COVID-19 and is associated with higher severity and mortality rates. T2DM patients are commonly treated with metformin monotherapy or metformin plus sitagliptin. In the present case-control, single-center cohort study, a total number of 112 T2DM patients suffering from COVID-19 and aged 44-62 years old were compared with 78 T2DM patients without COVID-19 and aged 42-56 years old. Both the patient group and the control group were allocated into four groups. Group A: T2DM patients with COVID-19 on metformin treatments plus standard therapy (n = 60); group B: T2DM patients with COVID-19 on metformin plus sitagliptin plus standard therapy (n = 52); group C: T2DM patients without COVID-19 on metformin treatments (n = 40); and group D: T2DM patients without COVID-19 on metformin plus sitagliptin (n = 38). The investigation duration was 2-3 weeks. Anthropometric measurements, serological and biochemical investigations, pulmonary radiological findings, and clinical outcomes were evaluated. Only 101 T2DM patients with COVID-19 continued the study, 71 (70.29%) with mild-moderate COVID-19 and 30 (29.7%) with severe COVID-19 were compared with 78 T2DM patients as a control. Inflammatory biomarkers (C reactive protein, ferritin, and procalcitonin), a lung injury biomarker (lactate dehydrogenase), and a coagulopathy biomarker (D-dimer) were elevated in severe COVID-19 patients compared with mild-moderate COVID-19 (p < 0.05) and T2DM patients (p < 0.05). However, metformin plus sitagliptin was more effective than metformin monotherapy in T2DM patients with COVID-19, as evidenced by the mitigation of oxidative stress, CT scan score, and clinical outcomes. The present study confirmed the protective effects of this combination against the development of COVID-19 severity, as most T2DM COVID-19 patients develop mild-moderate forms. Herein, the combination of metformin and sitagliptin may lead to more beneficial effects than metformin monotherapy.
ABSTRACT
Background: Migraine is one of the neurological diseases that have a negative impact on subjects' productivity and daily activity of patients. Introducing monoclonal antibodies as a valuable option for resolving the persistent problem of migraine is still under investigation. The current study aimed to evaluate the efficacy and safety profile related to Erenumab. Methods: A prospective study for clinical data collection and analysis from recruited therapy-refractory migraine subjects were carried through 6 months for each subject. All subjects received Erenumab 70 mg monthly. Each patient provided the clinical data monthly starting from 0 months and for the next 6 months. Migraine disability assessment (MIDAS) questionnaire was used for evaluation of the Erenumab efficacy every 3 months. In addition, data regarding adverse effects, migraine triggers, and the impact of previous COVID-19 on migraine severity were collected and analyzed. Results: Ninety subjects were recruited in the study. Erenumab injections resulted in a significant (p < 0.001) reduction in MIDAS score in the 3rd month compared with baseline, also this significance was continuous in the 6th month. In contrast, there was no significant difference in the 6th month compared with the 3rd. Previously infected COVID-19 subjects showed a higher severity of migraine attacks compared with non-infected subjects. Skin redness and local pain were the most common adverse effects 63.3%, 47.77% respectively associated with Erenumab. Conclusion: Using Erenumab therapy showed a great beneficial impact regarding the reduction of migraine-related disabilities. COVID-19 was related to the increased severity of migraine attacks.
ABSTRACT
BACKGROUND: Post-COVID-19 symptoms and diseases appeared on many survivors from COVID-19 which are similar to that of the post-severe acute respiratory syndrome (SARS) fatigue. Hence, the study aims to investigate and characterise the manifestations which appear after eradication of the coronavirus infection and its relation to disease severity. METHOD: About 287 survivors from COVID-19 were included in the study, each received a questionnaire divided into three main parts starting from subjects' demographic data, data about the COVID-19 status and other comorbidities of the subject, and finally data about post-COVID-19 manifestations. Response surface plots were produced to visualise the link between several factors. RESULTS: Only 10.8% of all subjects have no manifestation after recovery from the disease while a large percentage of subjects suffered from several symptoms and diseases. The most common symptom reported was fatigue (72.8%), more critical manifestations like stroke, renal failure, myocarditis and pulmonary fibrosis were reported by a few percent of the subjects. There was a relationship between the presence of other comorbidities and severity of the disease. Also, the severity of COVID-19 was related to the severity of post-COVID-19 manifestations. CONCLUSION: The post-COVID-19 manifestation is largely similar to the post-SARS syndrome. All subjects recovered from COVID-19 should undergo long-term monitoring for evaluation and treatment of symptoms and conditions that might be precipitated with the new coronavirus infection.
