Vulvovaginal candidosis is one of the most frequent disorders in obstetrics and gynaecology. Candida albicans is commonly considered to be the true vaginopathic agent. The secreted acid proteinase might be especially relevant in the pathogenesis of vulvovaginal candidosis. A fluorometric determination of acid proteinase activity of clinical C. albicans isolates was carried out during the present work using fluorescamine. L-Leucyl-L-alanine was included as an internal standard and the results were expressed as nmoles of leucylalanine equivalents h-1 per 2 x 10(4) cells. The 13 isolates were taken from non-diabetic, non-pregnant women aged 22-35 years with vulvovaginal candidosis. Candida albicans ATCC 44858 was used as a control. The proteinase activity in culture supernatants was detectable starting from the mid- to late- exponential phase of growth, peaked between 30 and 46 h, and then declined. The control had an activity of 2.72 nmol h-1 per 2 x 10(4) cells, whereas eight of the samples had a lower activity (1.05 nmol h-1 per 2 x 10(4) cells on average) and five of the samples had a higher activity (6.53 nmol h-1 per 2 x 10(4) cells on average). The fluorometric determination of acid proteinase activity was found to be more reproducible and sensitive than the previously used spectrophotometric determinations.

Asymptomatic bacteriuria in infants in eastern Turkey.

In this study, the prevalence of asymptomatic bacteriuria (ABU) was investigated in the 146 infants without symptoms suggesting urinary tract infection, age ranged from 29 days to 15 months (mean 4.56 +/- 3.30 months). Our purpose was to determine the prevalence ofABU in infants living in Eastern Turkey and to define the relationship between pyuria and ABU in infants. Of 146 infants, 77 (52.7%) were males, and 69 (47.3%) were females. Although we would like to select randomized healthy infants for the study, 47 (32.1%) infants had a mild to severe malnutrition. While various microorganisms were cultured in 41 (28%) infants in the first urinary culture, only 18 (12.3%) infants had a positive culture in the second urinary culture. The prevalence of ABU was 12.3%. Although ABU prevalence was higher in the infants with malnutrition than those without malnutrition (14.8% 1 vs. 11.1%), there was not a difference between the groups (p>0.05). There was a positive relation between urinary culture positiveness and pyuria (p < 0.001). The prevalence of ABU was much higher (12.3%) than the literature data, which was probably related to very low socioeconomic status of our region where malnutrition and its related disorders are commonly seen. The high ratio might also be related to the method of urine collection, because we used sterile collecting bag, but not suprapubic aspiration method.

Serum vitamin-E levels and its relation to clinical features in nonalcoholic fatty liver disease with elevated ALT levels.

BACKGROUND: Oxidative stress and free oxygen radicals play an important role in the progression from simple fatty liver to steatohepatitis. Deficiency of antioxidants like vitamin-E has been reported to trigger this progression. The main aims of our study were to measure plasma vitamin-E levels in nonalcoholic fatty liver disease (NAFLD), to explain its relationship with biochemical parameters and to examine the possible therapeutic and prophylactic role of vitamin-E. METHODS: 52 patients with NAFLD and elevated liver function tests were enrolled. After 6 months of follow-up with a standard low-fat, low-calorie diet, changes in liver enzymes were evaluated. RESULTS: Deficiency of vitamin-E was detected in 16 patients with NAFLD. Homogenous echo pattern of the liver and attenuation was found to be significantly higher in the low vitamin-E group (p = 0.03). The low vitamin-E group had significantly higher levels of triglyceride (p = 0.02). After 6 months, patients in the low vitamin-E group did not respond to the diet and no decrease in ALT levels was detected (p = 0.04). CONCLUSION: This is the first study measuring the serum vitamin-E levels in nonalcoholic fatty liver disease. A correlation was found between low vitamin-E levels, high triglyceride levels, as well as sonographic findings, both of which are negative prognostic factors causing progression of fatty liver to steatohepatitis. Patients with low vitamin-E levels did not respond to a classical diet for fatty liver disease. Based on the data, we suggest that diet alone is not adequate for patients with fatty liver, and vitamin-E supplementation should be added.

Percutaneous drainage of hepatic abscesses: therapy does not differ for those with identifiable biliary fistula.

BACKGROUND/AIMS: Surgical drainage of pyogenic and amoebic hepatic abscesses has been an accepted therapy for decades. Modern imaging modalities have changed both the diagnostic and therapeutic management of many hepatic lesions, particularly abscesses. Specifically, percutaneous aspiration and drainage with either ultrasound or computed tomography guidance has been reported as an alternative treatment for hepatic abscesses in recent years. Little is known about aspiration of hepatic abscesses that communicate with the biliary tree. MATERIAL AND METHODS: Fifteen patients with hepatic abscesses treated by percutaneous aspiration and drainage are herein reported. Six had a demonstrable fistulous communication between the abscess and the biliary tree. RESULTS: During a four year period of follow-up, only two of these 15 patients experienced a recurrence. Neither had a biliary fistula complicating their abscess initially. CONCLUSIONS: Based upon this experience, it is suggested that percutaneous aspiration and drainage should be the initial treatment of choice of both pyogenic and amoebic liver abscesses even when large. Abscesses with demonstratable biliary fistulas have a larger mean volume than do those without fistulous involvement. The finding of a communication between the abscess and the biliary tree should not change this treatment approach.

Congenital hepatic fibrosis associated with cavernous transformation of the portal vein.

BACKGROUND/AIMS: Congenital hepatic fibrosis (CHF), which is one of the fibropolycystic diseases, occurs in various forms. Portal hypertension, a very common clinical feature of this condition, has been attributed to the compression of portal vein radicles in the fibrous bands. We investigated whether there are any other contributing factors in the development of portal hypertension in patients with CHF. METHODOLOGY: A total of 1285 patients with portal hypertension of different etiologies were studied using ultrasonography as the screening test. Forty-seven (including portal vein involvement and/or CHF) of these 1285 patients were prospectively studied to evaluate the etiology of the portal hypertension by portography, abdominal computed tomography, exploratory laparotomy, peritonoscopy, liver biopsy and laboratory tests. The patients with CHF were divided into two groups, according to whether or not they had portal vein involvement. RESULTS: Eleven (0.8%) of the 1285 patients with portal hypertension had CHF, and 41 (3.2%) had cavernous transformation of the portal vein (CTPV), resulting from different or unknown etiologies. Five patients had both pathologies (CTPV and CHF). In the 11 patients with CHF, there was CTPV in 5 patients, Caroli's disease in 2 patients, cholangiocarcinoma in 1 patient, inferior vena caval obstruction in 1 patient, and CHF in only 2 patients. There were statistically significant differences in the age of the CHF patients at clinical onset, the incidence of bleeding from esophageal varices, and laboratory findings between the 2 groups with and without CTPV. Despite a thorough investigation, we could not distinguish any predisposing factor in 25 of the 41 patients with CTPV. The incidence of CTPV was 48% in patients with CHF and 3.2% in patients with portal hypertension. CONCLUSIONS: These results suggest that the association of CTPV with CHF is not coincidental, but that CTPV may be associated with CHF and a new possible factor in portal hypertension, and that it can be a major factor in the manifestation of esophageal bleeding from varices.

What is the association of primary sclerosing cholangitis with sex and inflammatory bowel disease in Turkish patients?

BACKGROUND/AIMS: In the Western world, primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease that is associated with inflammatory bowel disease (IBD), particularly chronic ulcerative colitis and, to a lesser degree, Crohn's disease. The goal of this study was to determine the prevalence of PSC in Turkish patients with IBD and chronic amebic colitis, a disease that is endemic in Turkey. METHODOLOGY: During a 10-year period, between 1986 and 1996, a total of 81 IBD (64 ulcerative colitis and 17 Crohn's disease) patients and 127 patients with chronic amebic colitis were seen and evaluated with radiologic, serologic, immunologic and pathologic tests. Whenever a clinical or biochemical finding suggested the presence of co-existent hepatic and/or biliary disease, the patient was further evaluated by liver biopsy, auto-antibodies and endoscopic retrograde cholangiopancreatography (ERCP) to determine whether they also had PSC or some other form of liver disease. As a disease control group, a total of 752 patients with clinical and/or laboratory evidence of pancreaticobiliary disease were also studied. In 86 of these 752 patients (10%), a primary disorder of the biliary tree was diagnosed by ultrasonography, computed tomography, peritoneoscopy, liver biopsy, ERCP and abdominal laparotomy. In addition, all 86 patients of the control group were evaluated endoscopically in order to determine whether they had any associated gastrointestinal condition of the upper or lower gastrointestinal tracts. After establishing final diagnoses of IBD, amebic colitis and PSC, these patients were evaluated with respect to their socio-economic status. A high protein diet (1.8 gram/kg/day) was administered to those patients with chronic amebic colitis and IBD during the active period of the disease. RESULTS: Of the 208 patients (81 with IBD and 127 with chronic amebic colitis), no cases of PSC were identified. Of the 86 patients in the control group with primary biliary tract disease, 45 had a biliary system malignancy, 14 had primary biliary cirrhosis (PBC), 16 had PSC, 3 had Caroli's disease, 6 had a common bile duct cyst, and 2 had gallbladder adenomatosis. All but 1 of the 16 patients with PSC were female. CONCLUSIONS: These data suggest that, in contrast to findings in Western Europe and the USA, in Turkey: 1) PSC is not regularly associated with idiopathic IBD; 2) most patients with PSC are female; 3) PSC accounts for only 18% of patients with a primary disorder of the biliary tree; 4) the incidence of small-duct primary sclerosing cholangitis is greater than that reported in the literature; and, 5) the incidence of IBD and PSC in Turkey is relatively lower than in other countries.
