Twenty to 40% of hepatitis C virus (HCV)-infected patients do not have a recognized parenteral risk factor, suggesting that still-unidentified modes of transmission exist. In order to investigate potential routes of HCV transmission for patients with no recognized parenteral risk factor, we conducted a multicentre case-control study. A total of 450 HCV-seropositive patients with no history of transfusion or intravenous drug use and 757 controls were recruited from the general population and matched for sex, age, geographical residence and number of chronic diseases. All subjects answered an interviewer-administered questionnaire on potential risk factors for HCV. Eighty per cent of cases had chronic hepatitis or cirrhosis. Respective percentages of genotypes 1, 2, 3, 4 and 5 were 65, 14, 11, 5 and 4. Among the 66 items considered, multivariate analysis identified 15 independent risk factors for HCV infection: nosocomial [admission to medical (odds ratio, OR = 2.1) or surgical ward (OR = 1.7), digestive endoscopy (OR = 1.9), abortion (OR = 1.7)], outpatient treatments [cutaneous ulcer and wound care (OR = 10.1), diathermy (OR = 3.0), gamma globulin (OR = 1.7), intravenous (OR = 1.7) or intramuscular (OR = 1.4) injections, varicose vein sclerotherapy (OR = 1.6), acupuncture (OR = 1.5)] and lifestyle-associated [intranasal cocaine use (OR = 4.5), practice of contact sports (OR = 2.3), beauty treatments (OR = 2.0), professional pedicure/manicure (OR = 1.7)]. These factors could explain 73% of community-acquired hepatitis C. In conclusion, for patients with unexplained routes of HCV infection, our data incriminate previously unidentified risk factors (abortions, some dermatological procedures, outpatient injections, contact sports, beauty treatments, professional pedicure/manicure) and confirm those already recognized (hospitalization, digestive endoscopy, acupuncture and intranasal cocaine use).

As the treatment of cirrhosis improves, pregnancy in patients with cirrhosis is likely to become more common. Although maternal and fetal mortality is expected to similarly improve, pregnant patients with cirrhosis face unique risks. These include higher rates of spontaneous abortion and prematurity and a potential for life-threatening variceal hemorrhage, hepatic decompensation, splenic artery aneurysm rupture, and postpartum hemorrhage. Pregnancy outcome may be influenced by the underlying etiology of liver disease, as in viral and autoimmune hepatitis. Medications also impact the course of pregnancy, and must be tailored appropriately during this time.

Pregnancy in patients with advanced liver disease is uncommon as most women with decompensated cirrhosis are infertile and have high rate of anovulation. However, if gestation ensued; it is very challenging and carries high risks for both the mother and the baby such as higher rates of spontaneous abortion, prematurity, pulmonary hypertension, splenic artery aneurysm rupture, postpartum hemorrhage, and a potential for life-threatening variceal hemorrhage and hepatic decompensation. In contrary, with orthotopic liver transplantation, menstruation resumes and most women of childbearing age are able to conceive, give birth and lead a better quality of life. Women with orthotopic liver transplantation seeking pregnancy should be managed carefully by a team consultation with transplant hepatologist, maternal-fetal medicine specialist and other specialists. Pregnant liver transplant recipients need to stay on immunosuppression medication to prevent allograft rejection. Furthermore, these medications need to be monitored carefully and continued throughout pregnancy to avoid potential adverse effects to mother and baby. Thus delaying pregnancy 1 to 2 years after transplantation minimizes fetal exposure to high doses of immunosuppressants. Pregnant female liver transplant patients have a high rate of cesarean delivery likely due to the high rate of prematurity in this population. Recent reports suggest that with close monitoring and multidisciplinary team approach, most female liver transplant recipient of childbearing age will lead a successful pregnancy.

Wilson's disease is a rare autosomal recessive disorder of copper metabolism. It causes cirrhosis of the liver, consequently followed by disorder of the menstrual cycle and infertility. Successful decopperizing may lead to restoration of the ovulatory cycle and enable pregnancy. Increased copper levels may cause preeclampsia, intrauterine growth restriction and neurologic damages in the fetus. Pregnant women with decompensated liver cirrhosis face more complications, including bleeding from esophageal varices, liver failure, encephalopathy, and rupture of the splenic artery. We present a case of Wilson's disease in a patient who had spontaneously conceived three times. The first pregnancy ended with delivery of a healthy baby at term. In second pregnancy, medically induced abortion was performed in the 12th week because of deterioration of the underlying disease, liver cirrhosis with portal hypertension. In the same year, the patient underwent liver transplantation. Two years after the transplantation, the patient spontaneously conceived and delivered vaginally a healthy child.

Vascular disorders of the liver frequently affect women of childbearing age. Pregnancy and the postpartum are prothrombotic states. Pregnancy seems to be a trigger for Budd-Chiari syndrome in patients with an underlying prothrombotic disorder. Whether pregnancy is a risk factor for other vascular liver disorders is unknown. In women with a known vascular liver disorder and a desire for pregnancy, stabilisation of the liver disease, including the use of a portal decompressive procedure when indicated, should be reached prior to conception. The presence of esophageal varices should be screened and adequate prophylaxis of bleeding applied in a manner similar to what is recommended for patients with cirrhosis. Most women likely benefit from anticoagulation during pregnancy and the postpartum. Labor and delivery are best managed by a multidisciplinary team with experience in this situation. Assisted vaginal delivery is the preferred mode of delivery. Although the risk of miscarriage and premature birth is heightened, current management of these diseases makes it very likely to see the birth of a live baby when pregnancy reaches 20 weeks of gestation.

Parasites reside inside or outside their hosts and get host nutrition and blood. Here, we have emphasized economic losses in cattle caused by parasitic diseases due to ecto- and endo- parasites (flies, ticks, mites and helminths). We have outlined different methods/models including economic evaluation techniques and dynamic analysis as a major class, used for the calculation of economic losses caused by parasites in cattle. According to already conducted studies, a decrease in production is mentioned in quantity and percentage while financial losses are expressed in the form of account with respect to per head, herd or for the specific study area. The parasites cause the reduced production and financial losses due to control, treatment and mortality costs. We calculated the average decrease in milk production and organ condemnation as 1.16 L animal-1 day-1 and 12.95%, respectively, from overall cattle parasitic infections. Moreover, the average calculated financial and percentage losses were US$ 50.67 animal-1 year-1 and 17.94%, respectively. Economically important parasitic diseases mentioned here are caused by specific spp. of protozoans and helminths according to data collected from the literature. Protozoan diseases include tick-borne diseases, coccidiosis, neosporosis, trypanosomiasis and cryptosporidiosis. Losses due to tick-borne infections were encountered for decreased milk production, mortality, treatment and control. Losses from coccidiosis were due to decreased weight gain, treatment costs and mortality. While abortion losses were encountered in neosporosis. Trypanosomiasis caused losses due to a decrease in milk yield. Moreover, only diagnostic (conventional or molecular techniques) cost was taken into account for cryptosporidiosis. Economically important nematode parasites are Oesophagostomum spp., Cooperia spp., Trichostrongylus spp., Strongyloides spp., Ostertagia spp. and Haemonchus placei. Due to the zoonotic importance of echinococcosis, Echinococcus granulosus is the most economically important cestode parasite. Losses caused by echinococcosis were due to organ condemnation, carcass weight loss and decreases hide value, milk production and fecundity. While, fascioliasis is one of the most economically important trematodal disease, which causes cirrhosis of the liver due to parasite migration, and thus, the organ becomes inedible. So, it would be helpful for farmers and researchers to approach these methods/models for calculation of parasitic losses and should adopt suitable measures to avoid long-term economic losses.

In brief, the classic form of Wilson's disease (WD) is an autosomal-recessive condition with hepatic, neurologic, psychiatric and systemic manifestations. However, the diagnosis should not be excluded because of a family history consistent with autosomal-dominant transmission. The latest next-generation sequencing (NGS) studies have demonstrated a gap between phenotype and genetic prevalences, and also suggest that WD may still be underdiagnosed. In a majority of WD patients, early recognition and appropriate treatment can result in resolution of symptoms and/or improved quality of life. Thus, finding WD in patients aged>40 years or with thrombocytopenia, hemolytic anemia, unexplained bone pain, amenorrhea, repeated spontaneous abortion or renal lithiasis is of major importance. These symptoms can all be found on their own or in association with mild-to-incapacitating neurological and/or neuropsychiatric manifestations. While brain lesions of the lenticular, midbrain and dentate nuclei are classic, white-matter changes and cortical lesions may also be observed: these are often asymmetrical with frontal lobe predilection and, when extensive, associated with a poor prognosis. These lesions are due mainly to copper deposition, but may also be related to focal accumulation of other metals, such as iron and manganese. A new biological marker called 'relative exchangeable copper' (REC) facilitates diagnosis and familial screening. Patient monitoring is important to ensure treatment adherence, efficacy and tolerability, and to detect rare complications such as copper deficiency induced by chronic copper chelation and hepatocarcinoma in patients with cirrhosis. Currently used treatments are copper chelators and zinc salts. Therapeutic perspectives are liver transplantation, new copper chelators as tetrathiomolybdate, hepatocyte/tissue transfer and gene therapy.

Pregnancy in women with portal hypertension is high risk due to the danger of variceal haemorrhage, which complicates 15-34% of cases. Variceal bleeding in pregnancy to women with non-cirrhotic portal hypertension is associated with increased risk of abortion (29%) and perinatal death (33%). Pregnancy in women with cirrhosis while less common due to hypogonadism, is associated with additional potential complications of hepatic decompensation and encephalopathy (10%), hepatorenal syndrome, ascites and bacterial peritonitis. Pregnancy in women with cirrhotic portal hypertension is associated with maternal death in 1.6%, and fetal loss in 10-66%. We present a case of non-cirrhotic portal hypertension in pregnancy, discussing two other potential critical complications of portal hypertension in pregnancy, splenic artery aneurysm (SAA) and pulmonary hypertension.
