Serum proteins C and S levels as early biomarkers for kidney dysfunction in hemophilic patients

Background: Hemophilia is an inherited genetic disease characterized by the inability to coagulate blood after injury. The rationale of the current study was to evaluate serum proteins S and C and correlate to kidney function test in hemophilic patients for early diagnosis of abnormality in renal function.Subjects and Methods: This study was conducted on 80 males subjects divided into four groups. Group I: Control: Healthy subjects. Group II: Renal dysfunction (serum Creatinine >2mg/dl): Group III: Hemophilic patients. Group IV: Hemophilic patients with renal disorder. Serum urea, creatinine, sodium, potassium, protein C and protein S level were determined. Resuts: Protein C and S levels showed a significant decrease in hemophilic/and with renal dysfunction (P < 0.001,p<0.001). The level of plasma protein C and S levels were positively correlated with increased urinary albumin (P < 0.01). Urinary albumin was increased about 15 folds in hemophilic patients with renal dysfunction and nephrotic patients as compared with the control group. The cut-off value in 90% patients at the hemophilic patients with renal dysfunction 70%. Positive correlations were observed between urinary albumin (r=0.66), and creatinine (r=0.73). Conclusion: These biomarkers showed good predictive values with regard to ROC-AUC (0.41 and 0.75 for Proteins C and S, respectively).Keywords: Hemophilia, renal dysfunction, protein C, protein S

Association of serum asymmetric dimethyl-arginine and troponin I levels as a risk of myocardial infarction in thalassemia

Background: The current study evaluated level of serum asymmetric dimethylarginine (ADMA) and its association to cardiac biomarkers in thalassemia patients for early diagnosis of abnormality in myocardial infarction. Subjects and methods: This study was conducted on 80 subjects divided into four groups each with 20 subjects. Group I: Control: healthy subjects. Group II: Myocardial infarction: Patients with elevated serum troponin T. Group III: thalassemia patients. Group IV: thalassemia with myocardial infarction patients: Included 20 thalassemia patients with Myocardial infarction. Serum samples were subjected for assay of creatine kinase (CK:MB), Lactate dehydrogenase, troponin I ,ADMA, Serum MDA level was determined. Results: Data obtained showed that serum CKMB, LDH1, AST, Troponin T and ADMA levels were significant elevated in MI with or without Thalassemia compared with control groups. Serum MDA was statistically significantly elevated in MI with or without Thalassemia compared with control groups. The serum level of troponin T showed an area under curve (AUC) of 0.92 ,(sensitivity 91.0 % and specificity, 88%). Also, the ADMA supported the diagnostic profile, showing an AUC of 0.85 with (sensitivity, 92.0%; specificity, 91,9%). Conclusion: Serum ADMA is sensitive marker for incidence of MI in thalassemia patients.Keywords: CKMB, LDH1, AST, Troponin T, asymmetric dimethylarginie, Thalassemia

Ultrasonographic and biochemical assessments as early prediction of polycystic ovarian syndrome in obese women

Backgroud: Polycystic ovary syndrome (PCOS) is considered as a common cause of hormonal disturbance and obesity. The diagnosis of PCOS was done by different methods including clinical signs as anovulation, hyperandrogenism, biochemical markers and ultrasounographic investigation. This study investigated comparative outcomes of ultrasonographic and biochemical markers for early prediction of PCOS in obese women. Subjects and methods: Seventy-five patients were clinically diagnosed with obese, PCOS and obese with PCOS and twenty-five normal age matched subjects were enrolled as control. Abdominal and transvaginal ultrasonographic for assessment of ovarian properties. In addition, BMI, serum free testosterone, dehydroepiandrosterone (DHEA), insulin, glycosylated hemoglobin (HbA1c) and LDL-c levels were evaluated. Results: In obese patients with PCOs (20%) ovaries revealed normal appearance in morphology while the rest (80%) showed PCOs in the form of cysts of 2\u20138 mm in diameter peripherally arranged around stroma. A significant elevation of free testosterone, DHEA and insulin in obese with or without PCOS compared with obese group (p<0.001). A positive correlation with hormonal abnormalities of increased HA1c, LDL-c, free testosterone, DHEA and insulin compared with obese only. Conclusion: According to our study findings, ovarian morphology combined with biochemical markers is more reliable for early prediction and diagnosis of PCOS for interpretation and management

Hemorrhagic fever in Saudi Arabia: challenge to public health, effective management and future considerations

Background: Viral hemorrhagic fevers (VHF) refers to a group of febrile illnesses caused by different viruses that result in high mortality in animals and humans. Many risk factors like increased human-animal interactions, climate change, increased mobility of people and limited diagnostic facility have contributed to the rapid spread of VHF. Materials: The history of VHFs in the Saudi Arabian Peninsula has been documented since the 19th century, in which many outbreaks have been reported from the southwestern region of Saudi Arabia. Despite presence of regional network of experts and technical organizations, which expedite support and respond during outbreaks, there are some more challenges that need to be addressed immediately. Gaps in funding, exhaustive and inclusive response plans and improved surveillance systems are some areas of concern in the region which can be dealt productively. This review primarily focusses on the hemorrhagic fevers that are caused by three most common viruses namely, the Alkhurma hemorrhagic fever virus, Rift valley fever virus, and Dengue fever virus. Conclusion: In summary, effective vector control, health education, possible use of vaccine and concerted synchronized efforts between different government organizations and private research institutions will help in planning effective outbreak-prevention and response strategies in future
