In the Czech Republic in 1991 2064 patients with chronic renal failure were treated in 43 haemodialysation centres. The number of newly enlisted patients was high--655 patients. Despite this the mean number of 196.5 patients/1 million population is lower than the European average. Fear of doctors is aroused by inadequate technical equipment and the lagging replacement of amortized equipment. The age of dialyzed patients is rising, the number of polymorbid patients and diabetics is increasing. It can be assumed that the mortality will increase and the number of transplantable patients will decline. A high incidence of hepatitis still persists. The most frequent cause of acute renal failure are complications after surgery. Acute haemodialysis on account of intoxication was made most frequently after intoxications with drugs.

We examined plasma antigen levels of tissue factor (TF) in 95 cases of disseminated intravascular coagulation (DIC), to investigate the role of TF in DIC. A significant elevation of plasma antigen levels of TF was observed in cases of DIC associated with cancer. However, no such significant elevation was observed in cases of DIC associated with acute promyelocytic leukemia (APL), acute leukemia except APL, blastic crisis of chronic myelogenous leukemia, non-Hodgkin lymphoma (NHL), sepsis or fulminant hepatitis. No significant elevation of TF was observed in patients without DIC, except 4 cases of cancer who developed DIC thereafter. Plasma antigen levels of TF were higher in both cases of DIC with renal failure and chronic renal failure without DIC than its levels in those without renal failure. Therefore, plasma antigen levels of TF in DIC patients with renal failure were considered to be carefully estimated. The levels of TF were decreased with the clinical improvement in some cases of DIC but were further increased or remained at high levels in patients who showed no improvement of DIC. Thus, plasma antigen levels of TF is an important marker to predict the development and/or prognosis of DIC, especially in patients with cancer.

The study group screened for anti-HCV comprised 789 subjects of hepatitis, renal failure, thalassaemia and healthy voluntary blood donors coming from Central India during July 1992 to November 1995. The prevalence of HCV was low (4.85%) among 103 patients of acute viral hepatitis (AVH) while it was higher (25.64%) among 117 patients of chronic liver disease (CLD) with the highest rate of 31.57 percent in 57 patients of cirrhosis. The anti-HCV positivity among 101 patients with hepatic failure was around 10 percent. High risk groups such as chronic renal failure (CRF) patients mainly on haemodialysis and thalassaemics receiving multiple blood transfusions showed the prevalence of anti-HCV in 41.9 and 25.45 percent respectively. Only 1.78 percent of the 280 voluntary blood donors showed positivity for anti-HCV. Comparison of the data on HCV in the present study with data from other parts of India showed a wide variation in the different centers. The higher prevalence of HCV among CRF patients and thalassaemics indicates the need for screening of the blood units for anti-HCV before transfusion to these high risk patients.

Hepatitis E virus (HEV) is prevalent in Asia and Africa. Recently, it was also described in Mexico, but epidemiologic data from other Latin American countries are scarce. The seroprevalence of anti-HEV in a referral hepatology unit in northern Brazil was determined by testing for anti-HEV IgG in 701 serum samples from our serum bank. Specimens analyzed were from 200 blood donors, 79 patients with acute viral hepatitis (AVH), 392 hemodialyzed patients, and 30 carriers of schistosomiasis. Duplicate test results for anti-HEV were positive in four (2%) of 200 of the blood donors, three (10%) of the 30 carriers of schistosomiasis, and in none of the 392 hemodialyzed patients. Fourteen (17.7%) of the AVH patients were positive, as were six (25%) of 24 with hepatitis A virus, three (11%) of 26 with hepatitis B virus, 0 (0%) of 12 with hepatitis C virus, and five (29%) of 17 with non-A, non-B, non-C hepatitis viruses. Among AVH cases, those with hepatitis A virus had a higher frequency of anti-HEV positivity compared with all other hepatotropic viruses (P < 0.0003). We conclude that HEV is prevalent in northern Brazil. The higher prevalence in patients compared with blood donors could be explained by the lower social condition of patients who sought public health service in this area, in contrast with the heterogeneous socioeconomic distribution of blood donors. Patients with AVH due to hepatitis A had a greater frequency of anti-HEV, probably because of similar routes of transmission for both hepatitis A and E viruses. Finally, the absence of anti-HEV in the hemodialyzed group could be explained by a lower immunologic response found in patients with chronic renal failure.

A retrospective analysis of survival time and causes of death has been undertaken in 109 patients treated for multiple myeloma (MM) at the Hematologic Clinic of the Russian Research Institute of Hematology and Transfusiology in 1979-1995. Group I included cases of mono- and group II-polychemotherapy (PCT). Survival in patients with MM increased significantly (from 27 to 43 months) after PCT. The main causes of death in MM patients of group I were chronic renal failure and infectious complications, while in group II-intoxication syndrome including blood toxicity, toxic hepatitis, etc. In cases of this grave disease, the effectiveness of therapy appeared to depend on both main and supporting treatment. Of great importance was profuse hydration using diuretics, active rheologic preparations, plasmapheresis and other counter-complication means. Following the administration of immunity correction drugs (thymaline, tactivin, immunoglobulin), infectious complication incidence in group II dropped from 22 to 8.3%. It is suggested that the effectiveness of MM therapy is determined by stage-by-stage approach, course cycling of PCT and adequate evaluation of its criteria. PCT courses should be supplemented with infusion detoxication measures, particularly, in cases of highly aggressive PCT schemes, and procedures of immunity correction, hemo-component therapy and plasmapheresis.

Anaemia is an almost invariable sign of chronic renal failure [1]. Although many factors have been implicated as causes of this anaemia, it seems probable that deficiency of erythropoietin is the main cause for most patients [2]. Institution of chronic dialysis can improve anaemia in end-stage kidney disease, continuous ambulatory peritoneal dialysis being reported as more successful [3]. The aim of this study was to investigate the influence of haemodialysis and continuous ambulatory peritoneal dialysis on anaemia during the first six months of treatment. We examined 21 persons (14 males and 7 females, aged from 18 to 78 years) on haemodialysis treatment and 13 persons (6 males and 7 females aged from 22 to 64 years) on continuous ambulatory peritoneal dialysis (Table 1). Standard procedures were used for measuring biochemical parameters. Urea and creatinine levels were high, almost incompatible with life, in all tested persons before dialysis treatment. During the first three months of both dialysis techniques urea and creatinine were significantly (p < 0.01) corrected, but remained above the normal ranges (Table 2). Patients on continuous ambulatory peritoneal dialysis have shown significantly (p < 0.01) lower urea and creatinine values compared to patients on haemodialysis (Graph 1). These data suggest better preservation of renal function and better control of the internal environment during continuous ambulatory peritoneal dialysis [6]. All tested patients were severely anaemic before the beginning of dialysis. During the first six months of haemodialysis erythrocyte count, haematocrit and haemoglobin levels were unchanged (Table 3). Transfusions and hepatitis episodes only temporary improved anaemia. Patients on continuous ambulatory peritoneal dialysis exhibited significant correction of anaemia already during the first three months of treatment (Graph 2). Though less significantly, haemoglobin values continued to rise even during the next three months. The reached haemoglobin levels were lower than normal, but significantly higher than values in patients on haemodialysis (p < 0.01), suggesting better control of anaemia during continuous ambulatory peritoneal dialysis. Transfusion requirement was irrelevant, and hepatitis was not noticed, so they cannot be held responsible for the improvement of anaemia. Greater iron consumption, illustrated by higher transferrin saturation, also confirmed increased erythopoitesis in patients undergoing continuous ambulatory peritoneal dialysis. They also had lower blood iron level than those on haemodialysis (who had) numerous blood transfusions. The improvement of anaemia during continuous ambulatory peritoneal dialysis may be the result of reduction in plasma volume [7] as well as an increase in red cell mass and a better clearance of middle molecules in comparison to patients on haemodialysis. The main cause is higher erythropoietin level [8]. All tested patients had low folic acid level. Patients who corrected anaemia showed fall in folat level. This was statistically remarkable during the first three months of continuous ambulatory peritoneal dialysis-from 3.64 ng/ml to 2.09 ng/ml. All these data suggest that both dialysis modalities are effective in the control of protein waste products level, but continuous ambulatory peritoneal dialysis has better influence on the improvement of anaemia that haemodialysis. This can be attributed to better removal of uremic toxins, improved protein metabolism, lower parathyroid hormone level and higher erythropoietin value due to peritoneal macrophage production.

We report 81 of 107 cases of hemolytic uremic syndrome (HUS), admitted between July 1994 and February 1996, following an outbreak of Shigella dysenteriae type 1 dysentery in Kwazulu/Natal. All patients, excluding 1, were black with a mean age of 38 months (range 1-121); 50 (61.7%) were males. The mean duration of dysentery was 11.3 days (range 1-41) and HUS 15 days (range 1-91). Most patients had acute oliguric renal failure (90.1%), 42 (51.6%) required peritoneal dialysis. Complications included encephalopathy 30 (37.0%), convulsions 12 (14.8%) and hemiplegia 2 (2.3%), gastrointestinal perforation 8 (9.9%), protein losing enteropathy 26 (32.1%), toxic megacolon 4 (4.9%), rectal prolapse 5 (6.2%), hepatitis 11 (13.6%), myocarditis 5 (6.2%), congestive cardiac failure 3 (3.7%), cardiomyopathy 3 (3.7%), infective endocarditis 1 (1.2%), septicemia 15 (18.5%), disseminated intravascular coagulation 17 (21%). Leukemoid reactions were found in 74 (91.3%) patients, hyponatremia in 56 (69.1%), and hypoalbuminemia in 67 (82.7%). Stool culture for Shigella dysenteriae type I was positive in only 7 (8.6%) patients; Shiga toxin assays were not performed. Outcome was as follows: recovery 32 (39.5%), impaired renal function 8 (9.9%), chronic renal failure 26 (32.1%), end-stage renal disease 1 (1.2%), and death 14 (17.3%) patients.

The prevalence of GBV-C infection in voluntary blood donors and in groups at high risk for parenteral exposure to infectious agents was studied. The high risk groups included chronic renal failure patients on haemodialysis, renal transplant patients and haemophiliacs from Gauteng. The presence of GBV-C RNA in these populations was determined using reverse transcription polymerase chain reaction (RT-PCR) in the 5' non-coding region (NCR) of the virus. Of the blood donors, 11.1% (95% CI 7.6, 15.8) were positive, whereas 23.8% (95% CI 12.6, 40.2) of haemodialysis patients and 23.5% (95% CI 15.9, 33.3) of the haemophiliacs were infected with GBV-C. The highest proportion of infection was in the renal transplant patients, where 41.2% (95% CI 35.1, 47.7) were found to have circulating GBV-C RNA. Serological markers for hepatitis B (HBV) and hepatitis C viruses (HCV) were also measured as indicators of other hepatitis viruses with important parenteral transmission routes. Of the GBV-C positive blood donors, 3.6% were also HBsAg positive and none were positive for HCV. The GBV-C positive patients on haemodialysis were not positive for either HBsAg or antibodies to HCV, but had evidence of past infection with HBV since 40% were anti-HBc positive. The greatest proportion of HCV positives was in the haemophiliac group, 91.3%, none of these were HBsAg positive but 39.1% had anti-HBc. In the GBV-C positive renal transplant patients, 4% had HBsAg, 13.3% had anti-HBc and 2.1% had antibodies to HCV. This is the first report describing the prevalence of GBV-C in South African populations.

Ischemic hepatitis, a relatively infrequent disorder occurring in 0.16% to 0.50% of patients admitted to medical intensive care units, often follows episodes of hypotension or acute heart failure. Investigating the clinical characteristics of patients with ischemic hepatitis may add to our understanding of the pathogenesis and significance of this syndrome. We therefore conducted a retrospective analysis of 34 patients to examine the possible contribution of the various baseline characteristics to the severity of the hepatic damage. In all patients liver disease was unexpected and in some, liver dysfunction dominated the clinical picture. All patients had high serum glutamic pyruvic transaminase (SGPT) and lactic dehydrogenase (LDH) levels (mean +/- SE, 2073 +/- 255 international units and 6085 +/- 748 international units, respectively). The mean SGPT/LDH ratio was 0.34. Most patients had coagulopathy with a prolonged prothrombin time (mean +/- SE, 5.86 +/- 1.37 international normalized ratio [INR]). The most common diagnosis on admission was respiratory distress secondary to various causes. Before the development of the hepatic dysfunction, respiratory failure and hypoxemia were observed in 68% of the patients, whereas hypotension was observed in only 38%. More than 90% of the patients had three or more associated comorbid conditions. The most frequent of these were left heart failure (88.2%), right heart failure (67.6%), chronic obstructive lung disease (58.8%), and chronic renal failure (55.9%). During the acute episode, more than 90% of the patients had transient deterioration of their renal functions. Hypoglycemia was noted in 11 patients (32.4%), and the glucose level was inversely correlated with the SGPT level (r = -0.43, p = 0.01). Stepwise multiple regression analysis showed that left heart failure, systolic blood pressure lower than 90 mm Hg, and female gender, together, accounted for 34% of the variance of the peak SGPT levels (p = 0.002). Fourteen (41.2%) patients died during the 3-month follow-up period, but none from the hepatic injury. None of the clinical or laboratory parameters measured predicted mortality. Clearly, ischemic hepatitis is associated with a high risk of death. The characteristic patients are those with multiple underlying systemic diseases and conditions, especially those with left heart failure. Liver function test results and levels of liver enzymes should be monitored in these patients, particularly when they are admitted for respiratory deterioration and episodes of hypotension.

A 43-year-old man underwent living related-donor renal transplantation because of chronic renal failure in 1991. During the transplant period, both donor and recipient were seronegative for hepatitis B surface antigen (HBsAg). The donor was seropositive for antibody to hepatitis B surface antigen (anti-HBs) due to hepatitis B virus (HBV) vaccination. After transplantation, FK506 and methylprednisolone had been administered to the patient as immunosuppressants. In 1993, HBsAg appeared in his serum. His alanine aminotransferase level elevated gradually during 1995 and then in 1996, general fatigue, ascites and jaundice developed. At this time his serum was positive for hepatitis B e antibody, contained more than 100000 Meq/mL HBV-DNA and 100% precore mutant. Despite subsequent intensive therapy, liver dysfunction progressed and this patient died of hepatic failure 2 months following admission. At autopsy, the liver exhibited cholestasis, fibrosis extending from the portal tracts, mild inflammation and hepatocytes with a ground-glass appearance. In addition, HBsAg and hepatitis B core antigens had accumulated in the hepatocytes. Consequently, the final diagnosis was fibrosing cholestatic hepatitis (FCH) due to precore mutant HBV infection contracted after renal transplantation. It is unclear when and where the recipient liver became HBV infected. Nevertheless, after renal transplantation, while receiving immunosuppressive drugs, HBV appeared to have the potential to cause hepatic failure and FCH may have been a fatal complication for the recipient.
