Rheumatologic and autoimmune manifestations in patients with chronic hepatitis C virus infection.

Hepatitis C virus (HCV) has been associated with several autoimmune and rheumatologic disorders. The aim of this study was to determine the incidence of these abnormalities in patients with chronic HCV. We studied 56 patients, 29 of whom (52%) had biochemical abnormalities that suggested immunological disorders. Cryoglobulinemia was detected in nine patients (22%), antinuclear antibodies in eleven (20%), rheumatoid factor in seven (19.27%) and hypocomplementemia in fourteen (29.16%). The most common clinical manifestations were: arthralgias (52%), myalgias (16%), xerostomia (28.5%) and xerophthalmia (14%). These results indicate the existence of a relationship between HCV and rheumatologic disorders. We conclude that HCV may play a role in the pathogenesis of these autoimmune phenomena, but more studies are required to define the extent of this role.

[The response to hepatitis B vaccine prior to orthotopic liver transplantation].

UNLABELLED: HBV hepatitis is a severe complication of orthotopic liver transplantation (OLT) due to the immunosuppression therapy. OBJECTIVES: The aim of this study is to evaluate the efficacy of the active HBV immunization on these patients before OLT. PATIENTS AND METHODS: This was a prospective trial, with 34 patients (20 M and 14 F), that received a double dose (40 micrograms) of HBV surface proteic Ag, on the 0th, 30th and 60th days of the study and posterior control of anti-HBs levels. If there wasn't a response, they received two more doses on the 90th and 120th days. RESULTS: There was a seroconversion in 22 patients (64.7%). Chronic alcoholism determined a lower rate of response than other etiologies (p < 0.05); this was the same in HCV chronic liver disease (p < 0.01). During their follow up, two patients had acute HBV hepatitis: one of them presented a negative response from the beginning, and in the other, anti-HBs developed transiently, when the HBV markers appeared. CONCLUSIONS: Previous HBV active immunization in OLT patients with double dose in a quick sequence, determined a positive response in a high number of patients with a higher rate of seroconversion than in other studies. The response was not so high in patients with chronic alcoholism or HVC chronic liver disease. We conclude that HVB vaccination should be done in these patients.

[Mixed cryoglobulinemia associated with hepatitis C virus].

We report six cases of essential mixed cryoglobulinemia associated with chronic liver disease and positive HCV markers, who showed several acute symptoms of vasculitis, arthralgias, neuropathy and glomerulonephritis. The presence in the serum and cryoprecipitates of anti HCV antibodies detected by the second-generation ELISA (ELISA 2) and the of HCV RNA by PCR in the serum in all six cases, suggest an important role for this virus in the pathogenesis of mixed cryoglobulinemia.

[Ischemic hepatitis following liver biopsy in a patient with transplanted liver].

We report a case of ischemic hepatitis following a percutaneous liver biopsy in a 51 year old female patient, who had had an orthotopic liver transplant 6 months before. The angiographic study demonstrated a marked stenosis in the hepatic artery at the anastomosis site and a small arterioportal fistula. We suggest that the percutaneous liver biopsy was partially responsible for the ischemic hepatitis, due to the development of a small arterioportal fistula in a previously damaged vascular area with hepatic artery stenosis.

[Hepatic angiosarcoma with splenic metastasis].

Angiosarcoma of the liver is an extremely rare tumor with a rapidly fatal course. This report describes the case of a 52-year-old male with an hepatic angiosarcoma not related to any known carcinogen. The hepatosplenic metastases and the brief clinical course, did not let us to complete diagnostic and therapeutic strategies.

Acute pancreatitis associated with milk allergy.

We are reporting the case of a 23-yr-old patient who had recurring episodes of acute pancreatitis characterized by the typical abdominal pain, elevated serum levels of pancreatic enzymes, and enlargement of the pancreas and edema on sonogram. These episodes were accompanied by facial erythema with conjunctival injection, generalized pruritus, diarrhea, and eosinophilia, and they were induced by the consumption of milk. The serum levels of IgE specific to cow milk proteins and to beta-lactoglobulin were increased. We suggest that these episodes are caused by a milk allergy (milk), that has been described as an unusual cause of acute pancreatitis.

[Transjugular hepatic biopsy. Apropos the first 100 cases and a review of the literature].

Under certain conditions a percutaneous liver biopsy cannot be carried out. In many of these patients transjugular liver biopsy is the correct option. We present our first hundred biopsies: in 92 cases a liver specimen was obtained; in 80 cases (87%) the tissue specimen allowed the histopathologic diagnosis; in five cases perforation of the hepatic capsule was observed, without producing hemoperitoneum. The mortality in our series was nil. In our experience and the revision of the literature, we consider that transvenous (transjugular) needle biopsy is an efficient and reliable procedure.

[Survey of informed consent in a gastrointestinal endoscopy unit].

OBJECTIVES: Gastrointestinal endoscopy, like all diagnostic and therapeutic techniques, must be preceded by written informed consent. The aim of this study was to evaluate the patients' acceptance and understanding of the aim of informed consent as well as to determine their perception of the investigation. METHODS: For 2 months, informed consent forms were given together with a questionnaire to 221 consecutive patients who underwent diagnostic gastrointestinal endoscopy. RESULTS: Distribution of the patients according to level of education was: university graduated (6.5%), high-school graduate (21.1%) those who had completed primary school (48.6%) and those with no schooling (23.9%). The document was read by 144 patients (65.1%) and the attending physician had previously explained it to 69.6%. Informed consent was understood by 90.7% of the patients who read the document. Understanding was related to education (university and high-school graduates (83.3%) vs. those who had completed primary school or who had no schooling (60%); p < 0.005) and was not related to the information given by the attending physician. Patients' opinion on the aim of informed consent was: absolve the doctor of responsibility (42%), provide information in the patients' interests (51.1%) and senseless document (42%). Signing the document provoked fear in 20% of those surveyed. This fear was greater in patients who had not been informed by the attending physician (31.2% vs. 14.5%; p > 0.01). CONCLUSIONS: Informed consent is understood by most patients who read the form but a significant proportion perceive it as designed to defend the physician. When the technique is explained by the attending physician and the doctor performing the procedure, acceptance is increased and fear is reduced.
