Abstract

OBJECTIVE: The aim of the study was both to evaluate the natural outcome of acute hepatitis C (AHC), in this factors influencing chronicity of HCV, and to assess results of antiviral therapy in acute phase of disease. PATIENTS AND METHODS: Seventy-seven pts with diagnosis of AHC (all HCVRNA-positive, in this 44 anti-HCV-positive at entry) were seen. Sixty-four of them (F/M: 33/31; mean age: 45.4y +/- 16.0) were non-treated (NT pts) with IFN during 6-months follow-up and thirteen patients (F/M: 5/8; mean age: 36.6ys +/- 11.9) were treated (T pts) with IFN. Antiviral therapy was started within 2 to 18 (median 10) weeks after the onset of AHC including seven pts with IFN alpha-2b at 5MU thrice weekly (TIW) and one pt with IFN-alpha-2a at 6MU TIW for 24 weeks, three pts with combined (Rebetron) therapy according to HCV genotype (1F/3a for 24 weeks and 2M/1b for 48 weeks) and two pts with PEG-Intron for one month followed by Intron at 3MU TIW for 20 weeks. RESULTS: 64.1% of NT pts developed chronic hepatitis. In multivariate logistic regression analysis age > 40y, nonicteric course and medical procedures as route of infection were independently and significantly associated with chronicity. Ten of the thirteen (77%) treated pts presented sustained response (SR) at the end of follow-up. Only one seronegative pt no responded to the therapy. The others 12 pts (all seropositive) presented rapid normalisation of ALT levels. However, 3 of them developed breakthrough between 12 and 20 week of therapy and ribavirin was added with beneficial effect. At the end of treatment point, all seropositive patients showed biochemical and virological response but two (with breakthrough history) of them relapsed. CONCLUSIONS: Seropositive, nonicteric patients with acute hepatitis C should be treated as soon as possible and pegylated-IFN for 24 weeks seems to be currently the best choice. Combination therapy with PEG and ribavirin could be proposed to the patients who failed to monotherapy. The beneficial effect of AHC therapy is indicative for necessity of creating conditions for diagnosed AHC more frequent than hitherto.

The effect of acute pain crisis on exhaled nitric oxide levels in children with sickle cell disease.

Exhaled nitric oxide (FE(NO)) has been shown to be decreased in children with sickle cell disease. We sought to evaluate the effect of sickle cell vaso-occlusive crisis (VOC) on FE(NO) levels. We measured FE(NO) levels in 42 children with sickle cell disease, 29 in their baseline health and 13 during an acute VOC. There was no difference in FE(NO) levels between children at baseline (15.12 +/- 9.32 ppb) and those during an acute VOC (15.68 +/- 7.26 ppb; P = 0.794). FE(NO) is not a useful marker of acute VOC in children with sickle cell disease.

[Megadolichobasilar anomaly causing acute deafness with vertigo].

Megadolichobasilar anomaly, a dilatant arteriopathy of the basilar artery attributable to chronic arterial hypertension, can cause cranial nerve compression syndromes of the cerebellopontine angle or infarcts of the vertebrobasilar circulation. In this paper, we report on a patient with known megadolichobasilar anomaly and a partially thrombosed fusiform aneurysm of the basilar artery, who presented with acute-onset vertigo and subsequent deafness due to thromboembolic occlusion of the labyrinthine artery. Because of the vascular origin of the patient's symptoms, his vertigo disappeared over time while the deafness persisted.

Retrieval of a leaflet escaped in a Tri-technologies bileaflet mechanical prosthetic valve.

The escape of the prosthetic heart valve disc is one of the causes of prosthetic dysfunction that requires emergency surgery. The removal of the embolized disc should be carried out because of the risk of a progressive extrusion on the aortic wall. Several imaging techniques can be used for the detection of the missing disc localization. In this report we describe a 32-year-old man who underwent mitral valve replacement with a Tri-technologies bileaflet valve three years ago, and was admitted in cardiogenic shock. Transesophageal echocardiography showed acute-onset massive mitral regurgitation. The patient underwent emergency replacement of the prosthetic valve. Only one of the two leaflets remained in the removed prosthetic valve. The missing leaflet could not be found within the cardiac cavity. The abdominal fluoroscopic study and plain radiography were unable to detect the escaped leaflet. The abdominal computed tomography scan and the ultrasound showed the escaped leaflet in the terminal portion of the aortic bifurcation. To retrieve the embolized disc laparotomy and aortotomy were performed three months later. The escaped leaflet shows a fracture of one of the pivot systems caused by structural failure. This kind of failure mode is usually the result of high stress concentration.
