[Antibiotic resistance of Helicobacter pylori in Reunion Island: therapeutic consequences].

The aims of this paper were to assess resistance of Helicobacter pylori to antibiotics included in the so-called French triple regimens and to identify the possible causes of therapeutic failure in Reunion island. Antibiotic resistance was determined for 109 strains. All the strains were sensitive to amoxicillin and tetracycline, 93.6% were sensitive to ciprofloxacin, 92.7% to erythromycin and 60.6% to metronidazole. Fifty three patients who had previously tested positive for H. pylori received for one week regimen of amoxicillin (1 g bd), clarithromycin (0.5 g bd) and omeprazole (20 mg bd). Eradication rate after therapy was of 73.6%. Therapeutic failure was analysed for 9 patients using random amplified polymorphic DNA and the presence or not of antibiotic resistance. One cause of failure is clarithromycin resistance. These data show that triple therapy can be used in Reunion Island. In case of failure, sensitivity must be detected because the rate of resistance to metronidazole is over 30%.

[Prevalence of hepatitis A, B, C virus markers in Réunion (south hospital and Saint Pierre prison)].

We studied the prevalence of Hepatitis A, B, C in different groups in the population of the South of Reunion Island. The aims of this study were the following: to estimate the prevalence of Hepatitis C virus (HCV) (anti-HCV antibodies) and Hepatitis B virus (HBV) (anti-HBc, HBs Ag and anti-HBs) in a population of 1455 women, who delivered in the Centre hospitalier Sud Reunion (CHSR), to estimate the prevalence of these two viruses in a population selected for risk factors (100 prisoners), to estimate the prevalence of Hepatitis A in a group of 400 persons (aged 0 to 19) hospitalised in CHSR since 1st January 1998 (100 for each 5-year age bracket), to research risks factors in these populations and immunity. The overall prevalence of anti-HCV was 0.14% in pregnant women and risk factor associated was found in 28.9% of this population (2.9% history of transfusion, 0.21% drug users). In the group of prisoners seroprevalence was 2%, far below that of prisoners in France. Anti-HCV seroprevalence is weak in Reunion Island and very inferior to seroprevalence in the French population as in other Indian Ocean islands. This is due to the low risk of parenteral transmission. Anti-HBc was found in 90 serum samples from women (overall prevalence 6.35%) and of these 90 positive samples, 9 were positive for HBs Ag (overall prevalence 0.63%), 68 were positive for anti-HBs (4.81%) and 22 (1.54%) were anti-HBc isolated (without HBs Ag and anti-HBs). The overall prevalence of anti-HBs was 62.8%. In the population of 100 prisoners, 2 were HBs Ag positive, 10 anti-HBc positive (2 anti-HBc isolated, 2 associated with HBs Ag, 6 with anti-HBs). The prevalence of anti-HBs was 22%. The major risk factor observed in this population of prisoners was tattooing and/or piercing (46%). These results show that: Reunion island is an area of low endemicity for HBV virus. The measure of protective inoculation is well followed. i.v. drug abuse and previous transfusion are weak routes of transmission. In the group aged 0 to 19, overall prevalence of anti-HAV was 11.9% with the highest rate found among 15 to 19 year-olds (25%). Seroprevalence falls with socio-economic progress. At the present time, the endemic is intermediate in Reunion Island. Given immunity levels within the young population, there is a risk of outbreak. This risk is due to the conditions in Reunion Island, but also to people who travel to other Indian Ocean countries where endemicity is high. It is thus very important that a vaccination strategy be determined.

[Prevalence of hepatitis C virus infection in pregnant woman on the island of Réunion].

AIMS: The aim of this prospective study was to assess the prevalence of anti-hepatitis C virus antibodies in a population of pregnant women in Réunion. METHODS: Over a 6-month period, all blood samples of pregnant women who delivered at a hospital in the south of Réunion were tested with a third generation enzyme-linked immunoassay. In addition, risk factors for hepatitis C transmission were systematically looked for. RESULTS: Among the 1,455 women tested during this period, only 2 sera were found to be positive, resulting in a prevalence of 0.14%. One of these women had a history of intravenous drug use, whereas the other had no identified risk factor. This low prevalence was found to be associated with a low frequency of risk factors of C virus infection in this population: a history of transfusion and intravenous drug use was found in 2.9% and 0.21% of cases, respectively. CONCLUSIONS: The prevalence of hepatitis C virus infection is particularly low in Réunion. This low prevalence is explained by the rarity of risk factors for hepatitis C transmission in this region which is close to the African continent and has a similar high prevalence of hepatitis B virus infection.

[Penile metastasis of recto-sigmoid adenocarcinoma. Apropos of a case].

Metastases to the penis from rectocolic adenocarcinoma are extremely uncommon with 50 cases reported; the diagnosis is often delayed and the prognosis is very poor. The choice between an aggressive surgical approach and a palliative treatment is difficult, but surgery seems to give the best results in limited penile lesions. The authors report a case of metastatic involvement of the penis by a recurrent rectocolic adenocarcinoma in a 42 year old patient. A MR scan was performed before surgical treatment of both lesions.

Endoscopic management of obstructive jaundice due to portal cavernoma.

This report describes 2 cases of calcified cavernous transformation of portal vein of unknown etiology. In both cases the revealing symptom was jaundice due to extrinsic compression of the common bile duct by the cavernoma. Only 4 other cases have been previously described in the literature. The cause of the jaundice was discovered only during surgery and confirmed by arteriography. Endoscopic retrograde cholangiography allowed both the diagnosis and the palliative treatment of the stricture of the distal common bile duct. Surgical treatment could not be performed.

[Treatment of achalasia by pneumatic dilatation].

Between 1979 and 1988, 60 patients with achalasia were treated by pneumatic dilatation under general anaesthesia, using the Rider-Moeller apparatus. The diagnosis rested on clinical, radiological, manometric and endoscopic criteria. These 60 patients underwent a total of 99 dilatations: 63.3 per cent were dilated once and 37.7 per cent were dilated several times. Forty seven of the 60 patients were followed up for more than 12 months (mean: 44 months): 2 of them (4.2 per cent) had to be operated upon, while 45 (95.7 per cent) are asymptomatic. Immediate complications were perforation in one case and cardial fissure in another; both were treated medically and cured. There was no oesophagitis or peptic stenosis, and no patient died. These results are compared with those found in the literature. The authors underline the simplicity, safety and effectiveness of pneumatic dilatation and suggest that it should be used as first-line treatment of achalasia, surgery being performed only when dilatation fails.

[Celiac disease, autoimmune cirrhosis, chronic pancreatitis: apropos of a triple association].

We report the case of a 60 year old lady suffering from celiac disease and autoimmune cirrhosis who developed exocrine pancreatic insufficiency with canalicular lesions consistent with chronic pancreatitis. Celiac disease is known to be associated with either pancreatic insufficiency or liver disease, but association of all three diseases has not yet been described. We suggest that chronic pancreatitis be added to the list of idiopathic inflammatory pancreatitis of possible autoimmune origin, enabling to explain the pathophysiology of all three disorders with one hypothesis.

[Value of MRI in the study of hepatocellular carcinoma. Preliminary study apropos of 12 cases].

The authors have tested different MR imaging sequences to detect hepatocellular carcinomas. The most performing is a spin-echo T2-weighted sequence with long TR (1800 or 2000 ms), and three echoes. The first echo, early at 40 ms, may allow an analysis of the vessels, later, at 80 and 120 ms, the two other echoes permit a better visualization of the tumor. With this type of sequence, the method's sensibility is excellent.

[Gastric pseudolymphomas. Apropos of 3 cases. Review of the literature].

The authors report three cases of gastric pseudolymphoma, before going on to review the literature on the subject. The pseudolymphoma has only recently been identified in relation to other primitive gastric lymphoid growths, on the basis of histological and evolutional criteria, which show it to be benign. It raises two problems. Firstly, a practical problem of diagnosis, as it often visualizes radiologically and endoscopically as a malignant tumor, and this diagnostic uncertainty persists, even after endoscopic biopsy. This necessarily implies surgical management of the case, normally leading to a clear diagnosis based on study of the gastrectomy specimen. Histologically, a growth of this nature consists of a very large lymphoid hyperplasia, often of an organoid type, strictly confined to the mucosa, which, incidentally, shows no real recent or ancient ulceration. Cytologically, this lymphoid infiltrate is benign and the neighbouring nodes are always normal. Point by point, therefore, these characteristics distinguish the pseudolymphoma from the real lymphoma and the lymphoid hyperplasia associated with ulcers. Fluorescence microscopic study of the intracytoplasmic immunoglobulin, which was carried out in the cases treated by the authors, and also in another recent case reported in the literature, shows a polyclonal type immunofluorescence. The pseudolymphoma is therefore, a benign form of lymphomatosis without ulceration. The second problem concerns the real nature of the lesion: a local immunosuppressive pathology? An atypical lymphoid presarcomatous hyperplasia? In order to support these hypotheses, fresh tissue lymphocyte typing tests covering the entire field of digestive lymph pathology should be carried out to complete the intracytoplasmic immunofluorescent study of the immunologically competent cells.
