Among the 1,991 studies in Stroke with a site in United States, from their registry updates:
Various molecules (cytokines: interleukins, interferons and neural proteins) found in human and animal blood are reported to be elevated in acute stroke (Ischemic and hemorrhagic). Cytokines can be pro-inflammatory or anti-inflammatory. There are studies confirming level changes in serum of humans in the setting of several rheumatologic and cardiovascular diseases. As new molecular markers (cytokines and neural tissue markers) are established in scientific literature, stroke scientists are interested to evaluate the role of these in the pathophysiology of stroke. Investigators intend to study the role of these molecules in the development of stroke.
Acute stroke treatment has advanced considerably in the last 10 years with the establishment of comprehensive stroke centers and approval of neuro-interventional techniques. However, the molecular advancement in stroke pathogenesis has yet to reach a milestone in the world of stroke treatment. In our opinion, creating a database of acute stroke patients containing all pertinent medical demographics and clinical information along with the laboratory data, molecular levels of pertinent cytokines/neural factors from consenting patients, will help us define and delineate the most relevant molecules that are altered in acute stroke patients and can help us further improve us understanding of the role of these in acute stroke and thereby hopefully help in the improvement of our understanding and management of stroke. Moreover, analyzing the cytokines in stroke and ICH patients would help understand their role in the acute phase, which may become potential therapeutic adjuncts for tPA and endovascular thrombectomy.
Stroke is the fifth cause of all-cause mortality in US http://www.cdc.gov/stroke/facts.htm . Early identification and treatment not only prevent mortality but also morbidity. Recent advancement in the imaging and diagnostic technique and novel therapeutic modalities has dramatically helped to downgrade stroke from the list of top mortality index in the last 3 years. However, studies determining factors which help predict stroke outcome are still underway and much work needs to be done in this direction. Many factors currently are used to predict stroke outcome with varying results, for e.g. NIHSS is a good predictor of stroke outcome at 3 months; however, we need better predictors, outcome scales or outcome measures which are easy, reliable and has better specificity and sensitivity.
There is also some correlation of clinical and biochemical predictors in subarachnoid, cerebral venous thrombosis including Hunt and Hess, SAH score, WFNS-SAH grading among others with variable predictive quality. (Rosen et al; Neurocritical Care; April 2005, Volume 2, Issue 2, pp 110- 118: Subarachnoid hemorrhage grading scales).
During the acute phase of focal cerebral ischemia, there is an elevation of thrombin activity and a decline in fibrinolytic activity. Moreover, the role of pro-inflammatory cytokines has been proven in the last few decades, as markers of inflammation have been closely studied in mice models; there are indications that elevated levels correlate with the extent of ischemic injury. Various interleukins were found to be elevated in most if not all patients with acute ischemic stroke. Correlation of hemostatic (procoagulant and fibrinolytic markers) with inflammatory markers is under discussion, with no confirmed common marker identified as of yet.
As new cytokines and tissue markers are established in scientific literature, stroke scientists are interested in evaluating the role of these markers in the pathophysiology of stroke. The role of glial cell markers has been of remarkable interest. Recently, an astrocyte marker S100B has shown association with infarct size, neurological outcome, and prognosis. Moreover, analyzing the cytokines in stroke and ICH patients would help understand their role in the acute phase, which may become potential therapeutic adjuncts for tpa and endovascular thrombectomy. In summary, inflammation in acute stroke is an area of interest in the recent years, with the theoretical benefit of aborting the inflammatory chain during acute stroke might be useful in limiting stroke-related brain damage or hemorrhagic transformation in acute stroke.
Two sets of serum samples will be obtained and analyzed; one upon admission to the hospital, and the 2nd, the next morning after overnight fasting. Both sets of blood draw are done for a clinical purpose, and any extra stored sample that is drawn and not used by pathology will be used for the study. Twenty-five percent of the total stroke patient serum samples will be matched by appropriate controls to confirm the level changes in stroke patients. ELISA-PCR assays will be performed on serum samples.

Exclusion Criteria:
Adult stroke patients with the stroke diagnosis will be recruited on admission to the University of New Mexico Hospital. Serum and Urine measurement of cytokines from two sets of serum and urine samples will be done on the admission and at the 24-hour mark respectively, form the specimens collected for the clinical purposes and are meant to be discarded. Consent will be taken from the patients to use these samples for our study.
Other: Serum and Urine measurement of cytokines.
Age/Sex matched adult control patients without the diagnosis of stroke, myocardial infarction, inflammatory flare, acute trauma, neurodegenerative or neuroinflammatory disease (AD, PD, TM, PSP, etc.) except MS will be recruited on admission to the University of New Mexico Hospital. Serum and Urine measurement of cytokines from two sets of serum and urine samples will be done on the admission and at the 24-hour mark respectively, form the specimens collected for the clinical purposes and are meant to be discarded. Consent will be taken from the patients to use these samples for our study.
Other: Serum and Urine measurement of cytokines.
To evaluate serum cytokine levels and identifying serum inflammatory markers (serum interleukin-33, IL-37, IL-36, IL-4, IL-6, IL-10, IL-17, IL-23, IL-1, TNF, PDGF, VEGFM TNFa, ANNULIN, MMP-9, MMP-12, NFk-B levels plus metabolic products like MPO, etc and glial factors like GMF, SI000B, GM6001) in patients with acute ischemic \& hemorrhagic stroke.
Change in the cytokine levels at the 24-hour mark from the baseline levels done at the time of admission for acute stroke.
Investigators will assess the variations in the levels of cytokines and inflammatory biomarkers at the 24-hour mark from the baseline levels done at the time of admission for acute stroke. Their correlation with each other may enable investigators to identify and streamline their efforts on only a few cytokines, interleukins, glial factors or metabolic products proved to be altered in acute stroke patients.

Ran from May 2019 to primary completion in Dec 2021, 31 months.
Of 835 non-industry observational studies under Stroke, half reached primary completion within 41 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 92. This study's 31 months is below that.
Counting every sponsor, half of 897 studies reached it within 40 months; a quarter within 18 and three quarters within 85.
