Hepatitis virus infection in haemodialysis patients from Moldavia.

BACKGROUND: Although the epidemiology of hepatitis B (HBV) and C (HCV) now seems well established for Western European countries, in Central and Eastern Europe < 50% of all dialysis centres routinely test for hepatitis C antibodies since testing is not available or is not applied to all patients. This study describes the prevalence, risk factors and clinical significance of HBV and HCV infection for the haemodialysis population of the North Eastern region of Romania, Moldavia. METHODS: The presence of HBV antigens was determined with an ELISA kit (Wellcome, Abbot) and HCV antibodies with the ELISA-3 Ortho-HCV, third generation test. The following individual data were collected: gender, age, duration of dialysis, rural/urban domicile, actual and previous HBV status, actual HCV status, known acute, clinically evident hepatitis episodes in the last 3 years, monthly alanine aminotransferase (ALAT) and aspartate aminotransferase (ASAT) levels, complete biochemical hepatic assessment at the time of the study, transfusions for the past 3 years and family history. RESULTS: HBV and HCV prevalences were 17% (stable over the last 3 years) and 75%, respectively; co-infection was seen in 10% of the subjects. Hospitalization (nosocomial infection) for HBV, blood transfusions and duration on dialysis for HCV, emerged as the main risk factors for hepatitis infection. Socio-economic conditions appear to be equally important for HCV infection, since the prevalence was significantly higher among patients from rural, underdeveloped areas than urban areas (80.8 vs 60.3%), and infection was already present in a large proportion of patients (47%) before starting dialysis, without being related to previous disease duration or blood transfusions. HBV and/or HCV was not associated with a worse clinical or biochemical profile at the time of the study. However, infected patients had significantly more previous cytolytic episodes, with higher, transient increases in ALAT and ASAT levels. CONCLUSIONS: HCV infection is endemic among dialysis centres in Moldavia. Apart from previously well-known risk factors for hepatitis infection, our study demonstrates the negative impact of socio-economic underdevelopment. Simple measures such as enforced general asepsia rules, careful disinfection and equipment sterilization, routine testing of patients from economically disadvantaged areas and monthly, serial determination of hepatic enzymes should be the common practice in dialysis centres in Romania.

[Normal bone mineral content levels determined by quantitative computer tomography (QCT) in the population of Moldavia].

UNLABELLED: To determine by QCT-BMD the normal osteodensitometric levels in the population of both sexes (18-80 years) from Moldavia districts. MATERIAL AND METHOD: The study used the BMD (bone mineral density) option of CT PACE GE-CGR (QCT) device which compares the CT levels in the area of interest restricted to the trabecular area of L1-L4 vertebrae with the values of a phantom with different hydroxyapatite concentrations. In order to develop a regional standard, an average of 10 both sexes subjects free of osteoporosis-generating diseases were investigated per each 5-year age group, age range 18 to 80 years, selected at random from the 8 districts of Moldavia. In both genders, data were plotted against age and were analysed with linear regression tests and the evolution curve (age-related) for each gender was drawn. RESULTS: The levels of score Z in both sexes were obtained. The obtained standard may be used as a reference database for the QCT investigation of the spine both in the male and female Romanian population.

Medical geography of Moldavia: historical contribution.

The role of Hungarian surgeons and physicians in the medical care of Moldavia was discussed in its historical development. Two medico-geographical works about Moldavia in the first half of the 19th century were discussed: Andreas Wolff and the Moldavian Constantin Vernav wrote the related books.

[A seroepidemiologic and virological study of the presence of arboviruses in Moldavia in 1961-1982].

In Romania, St. Drăgănescu et al., Miszkolczy et al., based on clinical and epidemiological observations, affirmed the possible presence of "tick-borne encephalitis (TBE)". However, critical retrospective evaluation of certain others' papers published through 1958-1971 reveal some uncommon features. By way of example: a very high incidence of CF- and HI-antibodies in acute and chronic CNS illnesses as well as in general population; replication in nucleus and maturation in mitochondria of a strain of "TBE virus" isolated from a patient CSF; isolation of "group B arbovirus" from Ixodes persulcatus on Romanian territory. As known, this tick was not identified in Romania, "no tick-borne Flavivirus isolated outside the U.S.S.R. proved to be a strain of RSSE virus" and "no arbovirus (Alpha- and Flavivirus or Bunyavirus) was ever detected in nucleus". Based on the HI reaction with West Nile (WN) virus, strain Egypt 101, human, domestic and wild vertebrates sera, treated with acetone for removal of nonspecific inhibitors, were tested as part of a control study, in Moldavia in 1961. WN virus was selected for its capacity to crossreact in the HI test with many members of the family Flaviviridae, genus Flavivirus (formerly Group B arboviruses), including the agents of Central European encephalitis. In order to avoid the interference of nonspecific inhibitors, a new single radial haemolysis test for the assay of antibodies to haemagglutinating arboviruses was calibrated in 1979. The seroepidemiological study performed on all 19.853 sera (10.698 human, 6.452 domestic mammals, 2.477 wild small rodents and 226 migrating aquatic birds) pointed out a very low circulation of Flaviviruses in the investigated area. The attempts to isolate such viruses from Ixodes ricinus on suckling mice yielded a single strain of Kemerovo (genus Orbivirus) virus. The need of extending the study to other viruses transmitted by arthropods and rodents, and mainly on the haemorrhagic fever with renal syndrome, an illness already clinically identified in Moldavia, is emphasized. Final consideration of viability (specificity, sensitivity, accuracy and precision) of the tests used and the need for continuous quality control is also presented.

To the research of the gene pool of the Gagauz population of Moldavia.

Population genetic data on Gagauzes from Moldavia are reported here for the first time. AB0 and Rhesus blood groups, serum protein group (HP, TF, GC) and the red cell enzyme polymorphism PGM1 were determined in 190 Gagauzes. In addition to this the ability to taste PTC was tested. The following allele frequencies were found: AB0*0 = 0.5241, AB0*A = 0.3279, AB0*B = 0.1480; RH*D = 0.6083, RH*d = 0.3917; HP*1 = 0.3544, HP*2 = 0.6456; TF*C1 = 0.7472, TF*C2 = 0.1770, TF*C3 = 0.0730, TF*B = 0.0028; GC*1F = 0.1025, GC*1S = 0.5932, GC*2 = 0.3043; PGM*1+ = 0.5932; PGM*1- = 0.1000, PGM*2+ = 0.2607, PGM*2- = 0.1107. The frequency of the PTC*T allele was found to be 0.5298. These frequencies and genetic distance analyses show that the gene pool of the Gagauzes is similar to that of neighbouring southeastern European populations.

Serological researches in the south of Moldavia in connection with the problem of the ethnogeny of the Gagauzes, the Moldavians and the Bulgarians.

With the aid of data of frequencies of genetically determined blood group systems, the authors have tried to show the basic ethno-genetic directional patterns in Southern Moldavia and in the Dniester-Carpathian-Danubian region in its entirety. Blood Groups A1A27B0, RHESUS, MN, and KELL have been determined in six random samples from four Gagauz villages (n = 330), one Moldavian village (n = 101) and one Bulgarian village (n = 96). The analysis of gene frequencies demonstrates genetic homogeneity of the total Gagauz population. Statistically reliable differentiation is observed only for the RHESUS system. It is possible now to suppose that the haemotological types of modern Gagauz and Bulgarian populations have been developed on the basis of the Balcanic serogenetic types, partially transformed under influence of gene flow from probably Central Asian or other eastern centers. The position of the Moldavians on the serogenetic map of Europe is less certain, due to a considerable ambiguity in the allele frequencies of the various blood group systems. Founder effects may account for these observations. However, the genetic distance and cluster analyses carried out on the frequencies of the surveyed blood group systems have shown the affinity of Moldavians with the Romanians and Eastern European populations.

Circulation of influenza virus A(H1N1) in Moldavia (Romania) during 1978-1982.

The influenza virus A(H1N1) subtype that reappeared after an absence of 20 years was incriminated as an etiological agent of acute respiratory disease outbreaks in Moldavia (Romania). There were three epidemics in the winter--spring of 1978, 1979, and 1982, that affected mostly school communities and young adults. In 1980-1981 the circulation of A(H1N1) virus was limited. In all the epidemics mentioned the A(H1N1) subtype caused mild influenza cases, with minimal complications and insignificant mortality.

[The importance of some factors which endanger the eradication of malaria in Moldavia].

The present paper reports on the results of a haematologic and serologic survey carried out for assessing quantitatively and qualitatively the importation of malaria, in terms of the two routes of penetration of plasmodia in Moldavia. Examination of peripheral blood droplets and testing by indirect immunofluorescence showed the higher proportions recorded in subjects coming from endemic malarial areas (6.6% and 70.9% respectively) than in our citizens travelling abroad in malarial areas (0.1% and 3.3% respectively). Attention is drawn to the essential components of the epidemiologic situation today: the existence of a dynamic reservoir of import plasmodia that can only be partly detected and is added to the residual autochtonous reservoir of P. malariae, to the receptivity of the human population and the presence of the natural transmitter vector P. vivax.
