Does Hepatitis C Virus Infection Increase Hematocrit and Hemoglobin Levels in Hemodialyzed Patients
(Dustri-Verlag Dr. Karl Feistle, 2003) Sahin, I.; Arabaci, F.; Sahin, H.A.; Ilhan, M.; Ustun, Y.; Mercan, R.; Eminov, L.
Objective: Some case reports indicated that red cell status increased after hepatitis C viral infection. The aim of study was to define the influence of hepatitis C infection (HCV) on red cell status in hemodialyzed patients. Materials and methods: A total of 49 (21 anti-HCV-positive and 28 anti-HCV-negative) patients with ESRD were included in this study. Exclusion criteria were blood transfusion and massive blood loss in the last 6 months preceding the study. None of the patients used any drug containing aluminum. Results: The prevalence of anti-HCV antibody was 42.8%. Mean age was 51.6 ± 14.3 in anti-HCV (+) group and 50.4 ± 17.0 in anti-HCV (-) group. There was no statistically significant difference between the ages of the 2 groups. Mean duration time of hemodialysis was significantly longer in patients with anti-HCV antibody (+) group (54.9 ± 34.2 months) compared to anti-HCV-negative group (12.5 ± 9.0 months) (p < 0.001). Mean hemoglobin (Hb) and hematocrit (Htc) levels were significantly higher in anti-HCV-positive patients than in anti-HCV-negative patients (Hb: 10.4 ± 1.8 g/dl, Htc: 30.5 ± 5.5% vs Hb: 8.8 ± 1.7 g/dl, Htc: 26.1 ± 5.3%) (for Hb p < 0.005, for Htc p < 0.007). There was no significant difference regarding the usage of rHuEPO between the 2 study groups (57.1% in anti-HCV antibody (+)/59.3% in anti-HCV antibody (-)) (p > 0.05). All patients not receiving rHuEPO did so because of economical reasons. Serum AST and ALT levels were significantly higher in the anti-HCV antibody-positive group compared with the anti-HCV antibody-negative group. (AST p < 0.04, ALT p < 0.04). Conclusion: Anti-HCV antibody-positive ESRD patients have higher hemoglobin and hematocrit levels compared to HCV-negative patients.
Eight Years' Experience of Uterine Rupture Cases
(2005) Zeteroglu, S.; Ustun, Y.; Engin-Ustun, Y.; Sahin, H.G.; Kamaci, M.
Ruptured uterus is a serious obstetric emergency with a high maternal and perinatal mortality. It is a preventable and common obstetric problem in developing countries. The objective of this study was to review the incidence, methods of diagnosis and maternal and perinatal morbidity and mortality associated with uterine rupture. Case notes were reviewed for all patients with a ruptured uterus at Yüzüncü Y1l University Medical Faculty Department of Obstetrics and Gynaecology from January 1995 to August 2003. Relevant data relating to the clinical characteristics of labour, operative procedures, maternal and perinatal outcome were assessed. There were 20 cases of ruptured uteri. The incidence was 0.40%. When patients referred from other hospitals were excluded, the revised ratio was 0.12%. There were 13 (65%) complete and seven (35%) incomplete ruptures. Nine (45%) cases occurred in patients with scarred uteri. Ten (50%) cases were grand multiparous. Subtotal abdominal hysterectomy was performed in five (25%) cases, total abdominal hysterectomy was performed in two (10%) cases and the remaining 13 (65%) cases had uterine rupture repair. There were two (10%) maternal deaths. Both of them were referred from other hospitals. There were seven (35%) perinatal deaths attributable to uterine rupture. Occurrence of uterine rupture is significantly associated with grand multiparity, scarred uterus, lack of antenatal care, unsupervised labour at home and low socioeconomic status of the patients. These factors are largely preventable. © 2005 Taylor & Francis.
