The presence of rhabdomyolysis secondary to multiple infections has been reported, predominantly viral, but also bacterial and fungal. It is well known that COVID-19 can present a wide variety of complications during the course of infection; however, the presence of rhabdomyolysis as an initial condition has not been reported so far. We report a case of rhabdomyolysis as an initial presentation in a patient diagnosed with SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) infection.
Immune thrombocytopenia (ITP) has been widely reported as a complication of SARS-CoV-2 infection, but to our knowledge, there have been no reports on the association of the COVID-19 vaccine with thrombocytopenia. Here, we report a case of secondary ITP in a patient who was recently immunised with the messenger RNA COVID-19 vaccine BNT162b2 (Pfizer–BioNTech).
ABSTRACT. Several studies have demonstrated that matrix metalloproteinases (MMPs) play a major role in atherosclerotic plaque disruption and lead to myocardial infarction (MI). We investigated the association between the MMP1 -1607 1G/2G (rs1799750), MMP3 -1612 5A/6A (rs3025058), and MMP9 -1562 C/T (rs3918242) polymorphisms and the risk of developing MI in a Mexican mestizo cohort. The genotype analysis was performed using the restriction fragment length polymorphism-polymerase chain reaction technique in a group of 236 patients with a history of MI and 285 healthy controls. Similar distributions of rs1799750 and rs3025058 were observed in both groups; however, the MMP9 rs3918242 T allele and the CT genotype were associated with the risk of developing MI (OR = 2.32, pC = 0.02 and OR = 2.40, pC = 0.02, respectively). Multiple logistic analysis was performed between MI patients and controls to estimate the risk, and after adjusting for identified risk factors, the CT + TT genotypes of MMP9 rs3918242 were found to be significantly associated with increased risk of developing MI than those with the CC genotype (OR = 2.88, P < 0.01). In summary, our results reveal that the rs3918242 polymorphism of the MMP9 gene plays a major role in the risk of developing MI.
Background: Coronavirus Disease 2019 pandemic since its first confirmed case, has changed the world. The need for accurate and truthful information is vital.Mexico and Latin America have been widely affected, so having local epidemiological data, will be of great clinical utility.Methods: A total of 33 hospitalized patients with Covid-19 pneumonia (either severe or critical) were identified from electronic health record in a third level care private hospital in Mexico City from March 13rd to April 13rd, 2020. We conducted a descriptive study of patients for characterization of the clinical, laboratory and radiologic findings, as well as complications.Results: The mean age was 60.6±12.68 years and 23 (69.7%) were males. Twentythree patients (69.6%) were overweight or obese. The median duration of symptoms before admission was 7 days. All the patients required mechanical invasive ventilation.The median duration of the mechanical ventilation was 12±2.6 days and all patients were extubated except one. All patients were started on antiviral treatment in the first 24 hours after admission once the diagnosis of Covid19 pneumonia was made. There was no difference between the treatment option and the length of stay. The extubation rate was higher (91.6%) than in other series, with no fatalities even though they were treated with different regimens.
Conclusions:This one-centre experience describes the epidemiology, treatment and outcome of 33 patients with severe or critical COVID pneumonia admitted to the ICU.Most patients in our series were overweight or obese male, which we observed were of
Small-sized apo(a) isoforms are an independent risk factor for MACCE in patients with coronary artery disease in follow-up. Lp(a) plasma concentration and apo(a) fibrin-binding were associated, although not significant.
Background. Thrombin has been implicated as a key molecule in atherosclerotic progression. Clinical evidence shows that thrombin generation is enhanced in atherosclerosis, but its role as a risk factor for coronary atherosclerotic burden has not been proven in coronary artery disease (CAD) stable patients. Objectives. To evaluate the association between TAT levels and homocysteine levels and the presence of coronary artery disease diagnosed by coronary angiography in patients with stable CAD. Methods and Results. We included 95 stable patients admitted to the Haemodynamics Department, including 63 patients with significant CAD and 32 patients without. We measured the thrombin-antithrombin complex (TAT) and homocysteine concentrations in all the patients. The CAD patients exhibited higher concentrations of TAT (40.76 μg/L versus 20.81 μg/L, p = 0.002) and homocysteine (11.36 μmol/L versus 8.81 μmol/L, p < 0.01) compared to the patients without significant CAD. Specifically, in patients with CAD+ the level of TAT level was associated with the severity of CAD being 36.17 ± 24.48 μg/L in the patients with bivascular obstruction and 42.77 ± 31.81 μg/L in trivascular coronary obstruction, p = 0.002. Conclusions. The level of in vivo thrombin generation, quantified as TAT complexes, is associated with the presence and severity of CAD assessed by coronary angiography in stable CAD patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
