Role of adiponectin, resistin and monocyte chemo-attractant protein-1 in overweight/obese asthma phenotype in children.

BACKGROUND: Asthma is a chronic inflammatory disorder of the airways with diverse overlapping pathologies and phenotypes contributing to a significant heterogeneity in clinical manifestations. Obesity may modify asthma risk, phenotype, and prognosis. A suggested mechanism linking obesity and asthma is through systemic inflammation. Adipokines secreted by adipose tissue were suggested to provide a link between obesity and asthma. OBJECTIVE: To have an understanding for the contribution of adiponectin, resistin and MCP-1 to development of distinct asthma phenotype in overweight/obese children through assessment of their serum level and correlation to pulmonary function tests. SUBJECTS AND METHODS: The study included 29 normal weight asthmatics, 23 overweight/obese asthmatic children and 30 controls. All cases were subjected to detailed history taking, thorough examination and pulmonary function tests. Serum adiponectin, resistin, MCP-1 and IgE were assessed to all recruited subjects. RESULTS: Adiponectin level was significantly higher in overweight/obese asthmatics (24900 ± 1600 ng/ml) compared to normal weight asthmatics (21700 ± 1700 ng/ml) and control (23000 ± 3200 ng/ml), (p < 0.001 & 0.051 respectively). Normal weight asthmatics had significantly lower adiponectin level than control, (p = 0.039). A significant low level of MCP-1 in overweight/obese asthmatics (149.5 (20-545) ng/L) compared to control (175 (28 -1123.5) ng/L), p = 0.037. No significant difference was found regarding resistin. Normal weight asthmatics had significantly lower FEV1% and FVC% compared to overweight/obese asthmatics (p = 0.036, 0.016 respectively). A significant positive correlation was found between (FEV1%, FVC) and BMI in normal weight asthmatics (P = 0.01, < 0.01 respectively) and a significant negative correlation between PEF and BMI (-0.42, p = 0.05) in obese/overweight asthmatics. Resistin/adiponectin ratio was not affected by sex, degree of asthma severity or level of asthma control in either normal weight or overweight/obese asthmatic. CONCLUSION: This work could suggest that adiponectin may play a role in overweight/obese asthma phenotype where it is possible to have a dual action (pro & anti- inflammatory). It seems that resistin had no role in asthma pathogenesis.

Prevalence and Risk Factors of Asthma in Children and Adolescents in Rabigh, Western Saudi Arabia.

The worldwide prevalence of asthma in children is variable. The different epidemiological definitions of asthma, the use of various methods of measurement, and the environmental variations between countries are responsible for such different prevalence rates. This study has been performed to identify the prevalence/risk factors of asthma in Saudi children/adolescents in Rabigh. A cross-sectional epidemiological survey has been conducted using the validated Arabic version of the "International Study of Asthma and Allergies in Childhood questionnaire". Data on the sociodemographic characteristics of participants and risk factors of asthma have also been collected. Three hundred and forty-nine Children/adolescents with an age range of 5-18 years have been randomly selected for an interview from public places and houses in different regions of Rabigh City. The prevalence rates of physician-diagnosed asthma, any wheezing, and wheezing in the last 12 months among children/adolescents (mean age: 12.22 ± 4.14 years) have remarkably increased in association with the rapidly developing industrialization of Rabigh from previously recorded rates of 4.9%, 7.4%, and 6.4% in the only study that has previously been conducted in Rabigh in 1998 to 31.5%, 23.5%, and 14.9%, respectively. The univariate analysis has detected some significant risk factors for asthma. However, in younger aged children (5-9 years), allergic rhinitis, associated chronic illnesses, and viral respiratory infection-induced wheezing have remained significant risk factors of any wheezing. Drug allergy, exposure to dust, and viral respiratory infection-induced wheezing have persisted as significant risk factors for wheezing in the last 12 months. Eczema in the family, exposure to perfumes/incense, and viral respiratory infection-induced wheezing have remained as significant risk factors of physician-diagnosed asthma. The results of this survey should be useful in future targeted preventive plans/measures with special attention to improving air quality to limit the progressive increase in asthma prevalence in Rabigh, as well as in other similar industrial communities.

Evaluation of the virtual learning environment by school students and their parents in Saudi Arabia during the COVID-19 pandemic after school closure.

BACKGROUND: Very few previous studies have involved school students or their parents in the evaluation of virtual learning environment (VLE). Thus, this survey was performed to evaluate the satisfaction of both school students and their parents with the VLE in the Kingdom of Saudi Arabia during the COVID-19 pandemic. METHODS: A cross-sectional questionnaire-based survey was distributed online for VLE evaluation. The questionnaire was based on previous studies and expert opinions from validated instruments for assessing distance education, integrative and literature reviews of VLE environment. A median value >3 indicated participant satisfaction in each of the 5 domains of the questionnaire as well as overall VLE satisfaction. The used questionnaire was checked after its implementation by all possible statistical means and it was found to be of acceptable validity and reliability. RESULTS: Six hundred and ninety-three participants including 571 Saudi citizens and 122 non-Saudi residents participated in this survey. The number of school students who agreed or strongly agreed were significantly lower than the number of students who disagreed or strongly disagreed with preferring the VLE over traditional education (p<0.001). The participants evaluated the VLE experience as unsatisfactory with a median value ≤3 for 4 out of 5 questionnaire domains with an overall satisfaction value of 2.8. Among the 117 participants who gave further written opinions/comments, 42(35.9%) participants supported the VLE as an alternative to traditional classrooms, if equipment and internet are made available and for the safety of their children. CONCLUSIONS: This is one of few available adequate population-based studies for exploring the VLE satisfaction of both Saudi citizens and non-Saudi residents school students and their parents. This study showed the participants' unsatisfactory VLE experience. The VLE is accepted as an alternative to traditional classrooms to keep up with learning and to maintain the safety of children and it can be a supplementary learning method but many measures are still needed to develop the VLE.

COVID-19 related posttraumatic stress disorder in children and adolescents in Saudi Arabia.

INTRODUCTION: The COVID-19 pandemic resulted in quarantine/lockdown measures in most countries. Quarantine may create intense psychological problems including post-traumatic stress disorder (PTSD) especially for the vulnerable critically developing children/adolescents. Few studies evaluated PTSD associated with infectious disasters but no Saudi study investigated PTSD associated with COVID-19 in children/adolescents. This study was undertaken to screen for PTSD in children/adolescent in Saudi Arabia to identify its prevalence/risk factors during COVID-19 pandemic and its quarantine. METHODS: A cross-sectional survey was conducted after 2 months form start of quarantine for COVID-19 pandemic utilizing the original English version and an Arabic translated version for the University of California at Los Angeles Brief COVID-19 Screen for Child/Adolescent PTSD that can be parent-reported or self-completed by older children/adolescents. Participants (Saudi citizens/non-Saudi residents) were approached online via social media. RESULTS: Five hundred and thirty seven participants were enrolled. The participants were 262 boys and 275 girls with a mean age of 12.25±3.77 years. Symptoms of no, minimal, mild and potential PTSD were identified in 15.5%, 44.1%, 27.4% and 13.0% of children/adolescents, respectively. The age, gender, school grade, and residence were not predictive of PTSD symptoms. Univariate analysis of risk factors for PTSD revealed that work of a close relative around people who might be infected was significantly different between groups of PTSD symptoms, but this difference disappeared during multivariate analysis. Children/adolescents of Saudi citizens had significantly lower median total PTSD score than children/adolescents of expatriate families (p = 0.002). CONCLUSION: PTSD associated with the COVID-19 and its resultant quarantine shouldn't be overlooked in different populations as it is expected in a considerable proportion of children/adolescents with variable prevalence, risk factors and severity. Parents/healthcare providers must be aware of PTSD associated with COVID-19 or similar disasters, so, they can provide children/adolescent with effective coping mechanisms.

Topical nitroglycerin in newborns with ischemic injuries: A systematic review.

BACKGROUND: Arterial catheterization is frequently performed in neonatal intensive care units with an inherent risk of peripheral ischemic injury, especially in preterm infants. The treatment options following vascular damage involve invasive and non-invasive modalities. The primary objective of this systematic review was to evaluate the evidence of the use of topical nitroglycerine (TNG) either alone or as adjunctive therapy. The secondary aim was to develop an approach to the treatment of catheter induced ischemia in infants based on the available evidence. METHODS: A comprehensive search was conducted of available databases for relevant articles that involved the treatment of peripheral tissue ischemia in neonates with the use of TNG. Citations were restricted to human subjects. RESULTS: Six hundred and eighty-nine articles were identified, and twenty-seven case reports and case series were compatible with the inclusion and exclusion criteria. Sixty-eight infants out of the 76 published cases (89%) experienced a favorable outcome and 79% (n = 60) demonstrated complete recovery with the topical application of TNG to the ischemic site. CONCLUSION: The available evidence demonstrates that TNG is effective for the treatment of peripheral ischemia in neonates after standard conservative measures have failed. However, due to the absence of robust evidence for this therapeutic modality, there are no uniform guidelines regarding the frequency, duration, and safety of TNG use. Planning the management of peripheral ischemia in neonates with TNG should be a multidisciplinary decision that includes close surveillance of blood pressure, methemoglobin levels, and follow up cranial ultrasound.

Tissue Doppler imaging versus conventional echocardiography in assessment of cardiac diastolic function in full term neonates with perinatal asphyxia.

BACKGROUND AND OBJECTIVE: Limited number of studies evaluated cardiac diastolic function in neonates with perinatal asphyxia using tissue Doppler imaging. The aim of this study was to evaluate the echocardiographic parameters in full-term neonates with perinatal asphyxia compared to healthy full-term neonates. Diagnostic value of echocardiographic parameters of diastolic dysfunction in predicting mortality in asphyxiated neonates was assessed. SETTING: Neonatal intensive care unit at the Obstetric and Gynecology Hospital, Cairo University, Egypt (a tertiary care center). PATIENTS AND METHODS: This study included 20 neonates with perinatal asphyxia (cases) and 20 healthy full-term nonasphyxiated neonates (as controls). The studied groups were assessed by conventional pulsed wave Doppler and tissue Doppler imaging. RESULTS: Among pulsed wave Doppler parameters, cases had statistically significant lower values (denoting more diastolic dysfunction) than controls as regards mitral E velocity (p = .04) and mitral E/A ratio (p = .04). Similarly, among tissue Doppler parameters, cases had statistically significant lower values (denoting more diastolic dysfunction) than controls as regards septal E'/A' ratio (p = .019), left ventricular E' velocity (p = .001), and E'/A' ratio (p < .001). Septal E'/A' ratio and right ventricular E'/A' ratio were significantly lower (p = .012 and p = .025, respectively) among nonsurvivors (denoting more diastolic dysfunction) compared to survivors. Moreover, cases had statistically significant higher values (denoting more diastolic dysfunction) than controls as regards septal (p < .001), left ventricular (p < .001), and right ventricular (p < .001) tissue Doppler-based myocardial performance indices. Asphyxiated neonates showed statistically significant higher evidence of left ventricular diastolic dysfunction than controls in both pulsed wave Doppler and tissue Doppler with p < .001 and p = .001, respectively; while there was no difference as regards right ventricular diastolic dysfunction. Tissue Doppler was able to detect higher number of neonates with left ventricular diastolic dysfunction than conventional pulsed wave Doppler. CONCLUSIONS: Tissue Doppler imaging was found to be able to detect diastolic dysfunction early in neonates with perinatal asphyxia specifically as regards the left ventricle. Assessment of myocardial function is important in asphyxiated neonates. Tissue Doppler imaging should be considered an integral part of assessment of cardiac function in asphyxiated neonates.

Is Spinal Dexmedetomidine Aggravating Hypotension after Tourniquet Deflation?

BACKGROUND AND AIMS: The addition of dexmedetomidine to spinal anesthesia decreases the incidence of tourniquet pain but may aggravate hypotension after tourniquet deflation. METHODS: Fifty patients were included in this prospective, double-blinded, randomized study, randomly divided into two equal groups of 25 patients each. Spinal anesthesia was performed using 2.5 mL of 0.5% hyperbaric bupivacaine plus 0.5 mL of normal saline in control group (Group C) or 2.5 mL of 0.5% hyperbaric bupivacaine plus 0.5 mL (5 µg) of dexmedetomidine in (Group D). Tourniquet pain was treated by 50 mg of meperidine and repeated in a dose of 20 mg, and the total meperidine consumption was calculated. After tourniquet deflation, heart rate and mean blood pressure were measured for 15 min in the operating room and at these times: before induction of anesthesia (baseline), after inflating tourniquet (inflation), 1 min before deflating tourniquet (predeflation), after tourniquet deflation (10 min postdeflation), and maximum blood pressure and heart rate changes. Duration of time that started before the minimum blood pressure and maximum heart rate was changed until recovery was recorded. RESULTS: Pain after torniquet inflation was significantly higher in the Group C compared to the Group D. The maximal change of blood pressure was lower in the dexmedetomidine than in the control group. The mean time between the maximal change in blood pressure reached and started to recover was 135 ± 14 s in the dexmedetomidine group and 80 ± 31 s in the control group (P < 0.01) and maximal heart rate change was lower in dexmedetomidine group than the control group. The time between the maximal heart rate changes until recovery was 113.2 ± 19 s in the dexmedetomidine group and 53.2 ± 11 s in the control group P < 0.01. CONCLUSION: Adding dexmedetomidine to spinal anesthesia decreases the incidence of tourniquet pain but aggravates the hemodynamic effect of tourniquet deflation.

Effects of body weight and posture on pulmonary functions in asthmatic children.

BACKGROUND: Asthma is one of the most common chronic illnesses in the world. Pulmonary function tests are important tools in monitoring of asthmatic patients. There is need for investigating if spirometric indices were affected by body weight or posture or not. OBJECTIVES: The aim of this study was to evaluate the spirometric measurements in standing and sitting positions in a group of Egyptian asthmatic children with different body weights. METHODS: Sixty patients were included. They were stable asthmatics and were following up in the allergy clinic. Spirometry was conducted at pulmonary functions laboratory of Pediatric Allergy and Chest Unit of New Children's University Hospital, Cairo. The one-way analysis of variance was used to test the differences between groups. The Duncan multiple comparison test was used to test the significant differences between each pair of groups. RESULTS: The study found that sitting FEV1/FVC is significantly lower in overweight/obese asthmatic children compared to normal weight asthmatic children (p value=0.046). CONCLUSION: There was no effect of weight on standing spirometric data. Weight showed significant negative correlation with asthma control level. We concluded that in overweight/obese asthmatic children, spirometric position might affect the results.

Efficacy of Adding Dexmedetomidine to Intra-articular Levobupivacaine on Postoperative Pain after Knee Arthroscopy.

BACKGROUND AND AIMS: Intrarticular ingection of local anesthetics in the knee joint decreases postoperative pain after knee arthrosopy. Dexmedetomidine an α2 agonist has sedative and analgesic effects and decreases postoperative pain after knee arthroscopy when injected intraarticulary. Levobubivacaine is a long acting local anesthetic with less toxicity than bubivacaine. We compared the analgesic effects of dexmedetomidine when added to intraarticular levobupivacaine in patients posted for knee arthroscopy. METHODS: Data were first tested for normality by Kolmogorov-Smirnov test. Study was done on 90 patients. Patients were divided into 3 groups 30 patients each. Group (C) received 50 ml saline only as a control group. Group (L) received 50 ml 0.25% levobupivacaine. Group (L/D) received 50 ml 0.25% levobupivacaine and dexmedetomidine 1µg.kg-1. (VAS) score was used to assess postoperative pain. Time of first pethidine demand and total dose of pethidine in the first 24 h were recorded, also postoperative complications such as pruritis, nausea and vomiting. SPSS version 16 was used for data analysis. P < 0.05 was considered significant. RESULTS: Postoperative VAS sore at different intervals was less in Group LD than Group L than Group C, time to the first pethedine injection in (min) was longer (39 ± 6, 31 ± 7, 21 ± 6), and total pethedine dose given (mg) was lower (36 ± 9.8, 64 ± 19, 102 ± 24) in Group LD than Group L than Group C respectively. CONCLUSION: Adding dexmedetomidine to intraarticular levobupivacaine in patients undergoing knee arthroscopy provides more analgesic effect with lower pain scores than levobupivacaine alone with less use of postoperative analgesics during the first 24 h.

Assessment of myocardial viability after acute ST- elevated myocardial infarction using stress speckle tracking echocardiography and cardiac MRI

Background: Speckle-tracking echocardiography has emerged as a unique technique for accurately evaluating myocardial function by analyzing the motion of speckles identified. Speckle-tracking measured under stress may offer an opportunity to improve the detection of dynamic regional abnormalities and myocardial viability. Objective: The aim of the current study was to evaluate stress speckle tracking to detect myocardial viability in comparison to cardiac MRI in post-STEMI patients. Patients and methods: 74 patients were prospectively enrolled in 18-month's study. Dobutamine stress echocardiography was performed 4 days post-infarction accompanied with automated functional imaging analysis of left ventricle during rest and then during low dose stress. All patients underwent a follow up stress echocardiography at 3 months with speckle tracking analysis. Cardiac MRI took place concomitantly at 4 days post-infarction and 3 months. Results: Investigating strain rate obtained with stress speckle tracking after revascularization predicted the extent of myocardial scar, determined by contrast-enhanced magnetic resonance imaging. A good correlation was found between the global strain and total infarct size (R 0.75, p< 0.001). Furthermore, a clear inverse relationship was found between the segmental strain and the transmural extent of infarction in each segment. Meanwhile it provided 81.82% sensitivity and 82.6% specificity to detect transmural from non-transmural infarction at a cut-off value of -10.15. Conclusion: Strain rate obtained from speckle tracking during stress is a novel method of detecting myocardial viability after STEMI. Moreover, it carries a promising role in post-myocardial infarction risk stratification with a reasonable prediction of reversible cardiac-related hospital re-admission

Intraperitoneal Levobupivacaine Alone or with Dexmedetomidine for Postoperative Analgesia after Laparoscopic Cholecystectomy.

BACKGROUND AND AIMS: Local anesthetic injection in the peritoneal cavity decreases intensity of postoperative pain after laparoscopic surgeries. We compared adding dexmedetomidine to intraperitoneal levobupivacaine in patients undergoing laparoscopic cholecystectomy. METHODS: A total of 105 patients were included in this prospective, double-blinded, randomized study. Patients were randomly divided into three equal sized (n = 35) study groups. Group C patients received intraperitoneal 40 ml normal saline as controlled group. Group L was given 40 ml 0.25% levobupivacaine. Group LD received 40 ml 0.25% levobupivacaine + dexmedetomidine 1 µg/kg. The degree of postoperative pain was measured by visual analog scale (VAS) score. The time of first analgesic demand was recorded and also total dose of painkiller in the first 24 h and postoperative complications were collected. SPSS version 16 was used for statistical analysis. P < 0.05 was considered statistically significant. RESULTS: Postoperative VAS at different time intervals was significantly lower, time to the first demand of painkiller (min) was longer (30.2 ± 14.4, 45.9 ± 20.1, and 56.5 ± 13.2), and total painkiller consumption (mg) was lower (203.5 ± 42.9, 117.8 ± 63.7, and 46.3 ± 41.3) in Group LD than Group L than Group C. CONCLUSION: Adding dexmedetomidine to intraperitoneal levobupivacaine is superior to and gives better results than levobupivacaine alone in patients undergoing laparoscopic cholecystectomy.

Viral causes of acute respiratory infection among Egyptian children hospitalized with severe acute asthma exacerbation.

BACKGROUND: Viral respiratory infections are associated with nearly 80% of asthma exacerbation episodes. These can have severe adverse outcomes in patients with established asthma. AIM: The aim of the study was to identify the viral causes of acute respiratory infection that precipitate acute asthma exacerbation in Egyptian asthmatic children. PATIENTS AND METHODS: The current prospective study was conducted in Cairo University Children's Hospitals from December 2010 to December 2011. All asthmatic children (n=130) aged 2-12 years admitted with asthma exacerbation due to severe lower respiratory tract infection were included. All cases were subjected to nasopharyngeal or throat swabs that were analyzed for common respiratory viruses, including respiratory syncytial virus (RSV), human metapneumovirus (hMPV), influenza B (Flu B), human parainfluenza virus (hPIV), influenza A (H1N1), and adenovirus (ADV) using the real-time PCR technique. All patients were followed up to record the outcome. RESULTS: PCR analysis was positive for one respiratory virus in 54 asthmatic patients (41.5%) and was negative in 76 patients (58.5%), with a high predominance of RSV (51.9%) and hMPV (25.9%) especially in winter and early spring months. Hypoxia was detected in all patients with RSV infection; of these patients, 21.4% were admitted to the ICU, 14.3% required mechanical ventilation, and 14.3% died. In contrast, among those with hMPV infection, hypoxia was detected in 71.4%; none required ICU admission or mechanical ventilation. CONCLUSION AND RECOMMENDATIONS: Viral etiology of lower respiratory tract infections constitutes an important cause of acute asthma exacerbation in asthmatic children admitted to children's hospitals in Cairo, supporting the need for large-scale multicentric studies on asthmatic patients over multiple years using a wider-panel PCR for detection of respiratory viruses.

Cryptorchidism in Egyptian neonates.

UNLABELLED: Cryptorchidism is one of the most common genital malformations in newborn males, but its etiology remains largely unknown. The observation of geographical variability in the prevalence of cryptorchidism suggests a role for environmental factors. The aim of this study was to determine the prevalence of this condition among Egyptian neonates. METHODS: The initial study population comprised 1000 neonates recruited from El Galaa maternity teaching hospital. To determine the risk factors for cryptorchidism in Egypt, 40 healthy full term infants were selected randomly during the same time period as a control group. RESULTS: Twenty-nine cases of cryptorchidism per 1000 newborn males were detected, i.e. a frequency of 2.9%; 10 (34.5%) had bilateral cryptorchidism while 19 (65.5%) had a unilateral lesion. Other congenital anomalies were detected in 5 (17.2%) of the cryptorchid newborns. Five factors were significantly associated with higher risk of cryptorchidism: gestational age of 37 weeks or less, birth weight equal to or less than 2.75 kg, cesarean delivery, steroid therapy and twin pregnancy. Using logistic regression, birth weight ≤ 2.75 kg was the only independent factor predicting cryptorchidism, with an odds ratio of 10.3 and 95% confidence interval of 2.9-36.4. CONCLUSION: These results highlight low birth weight as the cardinal risk factor for cryptorchidism. A larger scale multi-centric study is needed to clearly identify all the risk factors for cryptorchidism in Egyptian neonates.

Gender differences in presentation, management, and in-hospital outcomes for patients with AMI in a lower-middle income country: evidence from Egypt.

BACKGROUND: Many studies in high-income countries have investigated gender differences in the care and outcomes of patients hospitalized with acute myocardial infarction (AMI). However, little evidence exists on gender differences among patients with AMI in lower-middle-income countries, where the proportion deaths stemming from cardiovascular disease is projected to increase dramatically. This study examines gender differences in patients in the lower-middle-income country of Egypt to determine if female patients with AMI have a different presentation, management, or outcome compared with men. METHODS AND FINDINGS: Using registry data collected over 18 months from 5 Egyptian hospitals, we considered 1204 patients (253 females, 951 males) with a confirmed diagnosis of AMI. We examined gender differences in initial presentation, clinical management, and in-hospital outcomes using t-tests and χ(2) tests. Additionally, we explored gender differences in in-hospital death using multivariate logistic regression to adjust for age and other differences in initial presentation. We found that women were older than men, had higher BMI, and were more likely to have hypertension, diabetes mellitus, dyslipidemia, heart failure, and atrial fibrillation. Women were less likely to receive aspirin upon admission (p<0.01) or aspirin or statins at discharge (p = 0.001 and p<0.05, respectively), although the magnitude of these differences was small. While unadjusted in-hospital mortality was significantly higher for women (OR: 2.10; 95% CI: 1.54 to 2.87), this difference did not persist in the fully adjusted model (OR: 1.18; 95% CI: 0.55 to 2.55). CONCLUSIONS: We found that female patients had a different profile than men at the time of presentation. Clinical management of men and women with AMI was similar, though there are small but significant differences in some areas. These gender differences did not translate into differences in in-hospital outcome, but highlight differences in quality of care and represent important opportunities for improvement.

Sperm caspase-9 in oligoasthenoteratozoospermic men with and without varicocele.

OBJECTIVE: To assess sperm caspase-9 activity in infertile oligoasthenoteratozoospermic (OAT) men with and without varicocele. DESIGN: Prospective. SETTING: Academic setting. PATIENT(S): Eighty men: healthy fertile control subjects (n = 20), OAT (n = 25), and OAT associated with left-side varicocele (n = 35). INTERVENTION(S): History taking, clinical examination, semen analysis,assessment of seminal caspase-9. MAIN OUTCOME MEASURE(S): Semen analysis, sperm caspase-9. RESULT(S): Sperm caspase-9 was significantly increased in infertile OAT men associated with varicocele compared with OAT men without varicocele and healthy fertile control subjects. Sperm casapse-9 activity demonstrated significant negative correlation with sperm count, sperm motility, sperm velocity, sperm linear velocity, sperm linearity index, and sperm normal morphology. CONCLUSION(S): Sperm caspase-9 is exaggerated in infertile OAT cases with varicocele compared with infertile OAT cases without varicocele or healthy fertile men. Sperm caspase-9 demonstrated significant negative correlation with semen variables.
