ABSTRACT

The S100a7a protein is expressed in keratinocytes, its level is increased in acne condition. As isotretinoin therapy is known to alter some of S100 peptides, these could be important specific targets for acne therapy and may have an important role in clinical remission. A randomized controlled trial was held in a dermatology clinic in Baghdad, where 30 patients with moderate to severe acne vulgaris condition aged 16-31 years were enrolled. Five milliliters of venous blood samples were taken before and after 6 weeks of isotretinoin therapeutic trial. A placebo-control group of 26 acne patients was also enrolled. The S100a7a peptide was measured in both groups using the ELISA technique before and after the trial. High levels of serum S100a7a were found in acne patients of both groups before therapeutic trial. Following the trial, a significant statistical difference (p = .0003) was noticed between mean S100a7a protein level of study and control groups. By comparing the mean S100a7a protein level before and after isotretinoin therapy in the study group, a highly significant statistical difference was also found (p = .001). The current study showed a downregulatory effect of isotretinoin therapy on the S100a7a peptide mean level.

ABSTRACT

BACKGROUND: Hyperprolactinemia may reflect neuroendocrine stress reaction against acute coronary syndromes. AIM: The aim of the present study was evaluation of the serum prolactin level in the acute myocardial infarction (MI) regarding the current pharmacotherapy in management of MI. SETTING AND DESIGN: Cross-sectional clinical based study. SUBJECTS AND METHODS: This cross-sectional clinical study involved all patients with acute MI in a coronary care unit, a total number of 44 patients (45% males and 55% females) with age ranged from 40 to 75 years. A full history for modifiable risk factors and current therapy with aspirin, clopidogrel and or metformin, all patients are nonsmokers. The anthropometric measurements; for estimations of body mass index (kg/m(2)), electrocardiography was obtained. Fasting blood samples were taken in the morning from all patients and the sera used for estimations of routine investigation and determination of ischemic cardiac biomarkers like cardiac troponin I (cTnI) and serum prolactin level. RESULTS: This study shows a significant increase in the serum prolactin in acute MI as compared with the control. In acute MI serum cTnI elevation was correlated with serum prolactin increments. In metformin-treated group, there was a lowest prolactin serum level. CONCLUSIONS: Serum prolactin level increased in acute MI, and positively correlated with cardiac troponin level and reflects underlying cardiovascular complications.
