[Liver biopsy in patients with chronic hepatitis C virus infection: experience in a district hospital]. / Biopsia hepática en pacientes con infección crónica por el VHC: experiencia de un hospital comarcal.

INTRODUCTION: Liver biopsy is a highly useful tool in the evaluation of patients with chronic hepatitis C. However, the technique is not free of complications and presents a series of limitations (lack of representativity and interobserver variability in sample interpretation). Due to these limitations and the development of new noninvasive techniques, the role of liver biopsy is currently being reevaluated. MATERIAL AND METHOD: We performed a descriptive retrospective study of liver biopsies performed in patients with chronic hepatitis C virus (HCV) infection from January 2002 to January 2005. Age, gender, genotype, histology of the hepatic cylinder, and the percentage of patients who received treatment after liver biopsy was analyzed. The indications for biopsy in our patients and the reasons for nontreatment after biopsy were identified. We also analyzed whether the decision to start treatment was influenced by the histological grade of the lesion and whether there is any association between histological grade and transaminase levels. RESULTS: A total of 156 patients were included and 72% received treatment after biopsy. Transaminase levels were elevated in 86%. Alanine aminotransferase (ALT) levels were elevated in 92.30% of treated patients and in 66% of untreated patients. The most frequent cause of nontreatment after biopsy was fibrosis stage < 2. The histological results were as follows: G0 in 2%, G1 in 26.8%, G2 in 47.7%, G3 in 22.2% and G4 in 1.3%; stage of fibrosis was F0 in 7.2%, F1 in 30.1%, F2 in 37.9%, F3 in 19.6%, and F4 in 5.2%. Fibrosis was advanced (F >= 2) in 41% of the patients with normal ALT levels and was mild (< F2) in 33% of those with elevated ALT levels. CONCLUSION: Liver biopsy could be useful in patients with indication for treatment but a high risk of treatment-related adverse effects, as well as in those with normal transaminase levels, in whom the degree of fibrosis observed could influence the therapeutic approach.

[Crohn's disease and pregnancy. A descriptive and retrospective study]. / Enfermedad de Crohn y embarazo: un estudio descriptivo y retrospectivo.

OBJECTIVES: To determine the behavior of Crohn's disease during pregnancy, as well as the influence of this disease on the presence of low birthweight neonates. MATERIAL AND METHODS: A descriptive and retrospective study of all patients with Crohn's disease followed-up in the Hospital Costa del Sol was performed. A total of 124 pregnant women were included, classified in two groups: women who became pregnant before and those who became pregnant after Crohn's disease was diagnosed. In all patients, clinical and epidemiological data, disease activity during pregnancy and in the immediate postpartum period, type of assisted delivery, and neonatal birthweight were recorded. RESULTS: A total of 66.1% of pregnancies occurred before Crohn's disease was diagnosed, 31.5% occurred after diagnosis and 2.4% coincided with disease onset. No significant differences were found between women with and without a diagnosis of Crohn's disease in type of assisted delivery or low birthweight (p = 0.064; p = 0.643). All non-smoking patients remained in the quiescent phase and did not present disease recurrences during pregnancy. Among smokers, the disease remained inactive in 61.1%, while chronic activity or recurrences were observed in 38.9% (p = 0.003). CONCLUSIONS: The course of inflammatory bowel disease does not adversely affect pregnancy or the immediate postpartum period, nor does it increase the presence of low birthweight neonates or the number of cesarean deliveries performed.

[Pulmonary sarcoidosis associated with pegylated interferon in the treatment of chronic hepatitis C]. / Sarcoidosis pulmonar asociada a interferón pegilado en el tratamiento de la hepatitis C crónica.

Treatment with pegylated interferon is usually used in active chronic hepatitis C in association with ribavirin. The adverse effects of interferon include influenza-like syndrome and mild respiratory manifestations, which are highly frequent. Among the immunomodulatory effects is the possibility of inducing or exacerbating autoimmune phenomena such as cutaneous or systemic sarcoidosis. We present a new case of pulmonary sarcoidosis induced by pegylated interferon in a 35 year-old woman with chronic hepatitis C who developed respiratory symptoms 4 months after starting therapy with pegylated interferon associated with ribavirin. Radiological images showed a micronodular pattern in both pulmonary fields together with hilar and mediastinal adenopathies. Transbronchial biopsy confirmed the presence of sarcoidal granulomas. After the diagnosis of pulmonary sarcoidosis, antiviral therapy was suspended with subsequent resolution of the clinical symptoms.
