Farrugia A, Smit C, Buzzi A. The legacy of haemophilia: Memories and reflections from three survivors. Haemophilia 2022; 28:872-884.

Abstract
Following the publication of a book of personal memories by one of us (CS1,2), we have attempted to synthesis our joint memories of three ageing men, born in the era preceding universal access to treatment, in an attempt to describe our experience, our challenges and our reflections on the development of therapies, which have ensured that our experience of growing up with haemophilia in the 1950s and 1960s has not been mirrored by the current generation of patients. We describe our upbringing in different parts of Europe in health care systems which, while of varying standards, were all unable to offer the kind of care which developed after the development of specific therapies. We assess the effect of the contamination of these therapies by blood‐borne pathogens on our own development, and the development of our communities around us. In addition, we reflect on the lessons learnt, sometimes painfully, by our generation of people with haemophilia and how some of these enabled us to overcome substantial hurdles, survive and build productive lives. Finally, we survey the development of therapies in the past 20 years, and offer some reflections on how our experience can be integrated in a realistic expectation of what the future holds for our community, in our own affluent societies and in countries less advantaged economically. We hope that our thoughts may contribute to continued progress in the field of haemophilia care.

Abstract
Hepatitis C virus (HCV) infection is the leading cause of liver disease in hemophilia patients. In those with human immunodeficiency virus (HIV)/HCV coinfection, the rate of liver disease progression is greater than in HCV monoinfected individuals. Despite antiretroviral therapy, which slows HCV liver disease progression, some require transplantation. Whether transplant outcomes are worse in hemophilic (H) rather than nonhemophilic (NH) candidates is unknown. In order to determine rates and predictors of pretransplant and posttransplant survival, we conducted a retrospective observational study using United Network for Organ Sharing national transplant registry data, comparing HCV+ H and NH candidates. We identified 2502 HCV+ liver transplant candidates from 8 US university-based transplant centers, between January 1, 2004 to December 31, 2010, including 144 HIV+ (6%) and 2358 HIV-; 36 H (1%) and 2466 NH; 1213 (48%) transplanted and 1289 not transplanted. Other than male predominance and younger age, each were P < 0.001. Baseline data were comparable between H and NH. In univariate analysis, 90-day pretransplant mortality was associated with higher baseline Model for End-Stage Liver Disease (MELD; hazard ratio [HR] = 1.15; P < 0.001), lower baseline platelet count (HR = 0.9 per 25,000/µL; P = 0.04), and having HIV/HCV+ hemophilia (P = 0.003). In multivariate analysis, pretransplant mortality was associated with higher MELD (P < 0.001) and was significantly greater in HIV+ than HIV- groups (P = 0.001). However, it did not differ between HIV+ H and NH (HR = 1.7; P = 0.36). Among HIV/HCV+, posttransplant mortality was similar between H and NH, despite lower CD4 in H (P = 0.04). In conclusion, this observational study confirms that hemophilia per se does not have a specific influence on transplant outcomes and that HIV infection increases the risk of mortality in both H and NH patients.

Abstract
SUMMARY Despite continuous improvement in safety and purity of blood products for individuals with haemophilia, transmissible agents continue to affect individuals with haemophilia. This chapter addresses three viral pathogens with significant clinical impact: HIV, hepatitis C and parvovirus B19. Hepatitis C is the leading cause of chronic hepatitis and the major co-morbid complication of haemophilia treatment. Clinically, asymptomatic intermittent alanine aminotransferase elevation is typical, with biopsy evidence of advanced fibrosis currently in 25%. Current treatment is effective in up to 70%, and many new agents are in development. For those progressing to end-stage liver disease, liver transplantation outcomes are similar to those in non-haemophilia subjects, although pretransplant mortality is higher. HIV infection, the second leading co-morbid condition in haemophilia, is managed as a chronic infection with highly active antiretroviral therapy (HAART). HAART also slows hepatitis C virus (HCV) progression in those with HIV/HCV co-infection. Viral inactivation and recombinant technologies have effectively prevented transfusion-transmitted viral pathogens in haemophilia. Human parvovirus B19 infection, typically associated with anaemia or, rarely severe aplastic crisis, is a non-lipid enveloped virus, for which standard inactivation techniques are ineffective. Thus, nucleic acid testing (NAT) to screen the blood supply for B19 DNA is currently under consideration by the Food and Drug Administration. To the extent, viral inactivation, recombinant, and NAT technologies are available worldwide, and the lifespan for those with haemophilia is approaching that of the normal population. The purpose of this chapter is to provide an update on three clinically significant transfusion-transmitted viral pathogens.

Abstract
Hepatitis C is a major cause of morbidity and mortality in haemophiliacs who received clotting factor concentrates before the availability of virus-inactivated factors in the mid-1980s. Early studies gave conflicting indications as to the severity of hepatitis C (originally termed non-A non-B hepatitis), as mild, slowly progressive hepatitis was documented in several infants and young adults with haemophilia who were examined with repeat liver biopsies, whereas more progressive hepatitis and cirrhosis was documented in others. One major point of dispute was whether these discrepancies could in part be accounted for by epidemiological differences among studies, as hepatitis C acquired early in life may initially run a benign course and later worsen owing to spontaneous recrudescence of hepatitis or interference with such comorbidity factors as alcohol abuse or infection with the human immunodeficiency virus (HIV). In the mid 1990s, the latter infection overshadowed hepatitis C as a cause of death in this patient population. Because hepatocellular carcinoma is emerging as an important complication in haemophiliacs with long-standing hepatitis C virus (HCV) infection who survived HIV infection, and because of recent advances in treating HIV, morbidity and mortality associated with chronic hepatitis C have regained emphasis amongst haemophiliacs. The development of newer interferon-based therapies provides an opportunity for modifying the natural history of HCV infection in a substantial number of haemophilic patients.

Abstract
The haemophilias are inherited disorders in which one of the coagulation factors is deficient. Although deficiencies of factor VIII (haemophilia A) and factor IX (haemophilia B) are well recognised, von Willebrand's disease is much more common. Rare defects can occur in any of the coagulation factors. In the past, men with haemophilia were likely to die in their youth. With advances in diagnosis, and especially with development of safe and effective treatment, affected individuals can now look forward to a normal life expectancy. Complications of the disorder, particularly the development of antibodies that make treatment ineffective, and of treatment, such as transfusion-transmitted infections, have taken a severe toll on these patients. The future holds the realistic possibility of gene therapy. However, we must not forget that haemophilia is a worldwide disorder that requires significant economic resources not available for the majority.

Abstract
Three groups of Lebanese patients (haemophiliacs, patients on cycled cancer chemotherapy who were regularly receiving blood transfusions, and intravenous drug users) and a control group of healthy blood donors were checked for markers of infection with hepatitis viruses (B and C) and human retroviruses (HIV and HTLV-I). Compared with the controls, all three groups of patients were more likely to be seropositive for antibody to hepatitis C virus (anti-HCV), and the haemophiliacs and cancer patients (but not the relatively young drug users) were more likely to be seropositive for hepatitis B virus (HBV). All the haemophiliacs and cancer patients found to be carrying the surface antigen of HBV (HBsAg) and/or to be seropositive for anti-HCV had given the same result when tested before the screening of blood and blood products for HBsAg and anti-HCV became routine practice in Lebanon (a decade before the present study). The four intravenous drug users (IVDU) found seropositive for HBV (two cases) or anti-HCV (two cases) had seroconverted in the 2 years prior to the present study. In addition to highlighting the problem of HCV infection among IVDU, the present results emphasise the need for the careful screening of donated blood for all blood-borne viruses, and for the exclusive use of disposable equipment in the management of cancer patients. The anti-HBV vaccination of IVDU is recommended but only the results of further clinical evaluation will show whether the similar vaccination of patients on cycled cancer chemotherapy is of value. Although none of the patients or controls was found positive for anti-HIV-1, anti-HIV-2 or anti-HTLV-I, the routine screening of blood and blood products for these viruses (particularly for HIV) should remain mandatory.

Abstract
Our aim was to evaluate the severity of liver disease resulting from chronic hepatitis C in haemophilia or von Willebrand disease and the efficacy of 6 months treatment with interferon alpha and ribavirin. Fifty-five liver biopsies were performed in 43 patients without any bleeding complications, as seen with ultrasound immediately after the biopsy and 48 h thereafter. Histological changes were mild, with low scores for both inflammation and fibrosis, in spite of long exposure to blood products (mean 27 years). Two patients had compensated cirrhosis. Thirty-five out of 39 included patients completed study treatment. Hepatitis C virus (HCV)-RNA was negative in 77% (30/39) of patients at the end of treatment, and 36% (14/39) achieved a complete sustained response at follow-up 6 months after treatment. Treatment failure was more frequent in patients with virus genotype 1 compared with non-1 (P = 0.0003). The response rate correlated well with that of non-haemophilic patients. In summary: (1) liver biopsy was safe with our regimen; (2) liver disease in our patients was usually mild and had a slow progress; (3) only HCV genotype 1 predicted treatment failure; (4) our treatment results agreed with those from non-haemophilic patients.

Abstract
Because of changes in factor replacement therapy and in treatment of human immunodeficiency virus (HIV) infection, we examined death record data for persons with hemophilia A in the United States to evaluate effects of HIV infection on age and causes of death. Multiple cause-of-death data from 1968 through 1998 were examined to assess death rates for persons with hemophilia A. ICD-9 coded causes of death from 1979 through 1998 were examined to assess long-term trends. From 1979 through 1998, 4,781 deaths among persons with hemophilia A were reported, of which 2,254 (47%) had HIV-related disease listed as a cause of death. In the late 1980s, mortality among persons with hemophilia A increased markedly, and the age-adjusted death rate peaked at 1.5 per 1,000,000 population in 1992. Median age at death decreased from 55 years in 1979-1982 to 40.5 years in 1987-1990, and increased to 46 years in 1995-1998. In the period 1995-1998, the median age of hemophilia A decedents with HIV-related disease was 33 years, compared to 72 years for those without HIV-related disease; the most frequently listed causes of death for those without HIV-related disease were hemorrhagic and circulatory phenomena; the most frequently listed for those with HIV-related disease were diseases of liver and the respiratory system. From 1995 to 1998, hemophilia A-associated deaths decreased by 41%, with a 78% decrease among those who had HIV-related disease. Although HIV infection has adversely effected mortality for persons with hemophilia A, the marked recent decrease in the death rate among persons with hemophilia A appears to reflect advances in care for those with HIV-related disease and is consistent with a decline in HIV mortality observed in the general population.

Abstract
We report the relationship between hepatitis C virus (HCV) titre, liver histology and HCV genotype in patients with bleeding disorders. One hundred and thirty-two RIBA-2-positive patients, including 56 who were also HIV positive, were identified at our centre. Fifty of these patients, including nine who were HIV infected, underwent percutaneous liver biopsy. Liver histology was assessed using a modified histological activity index (HAI). Qualitative serum HCV PCR was positive in 87 (87%) of the 101 patients tested including 43 of 50 biopsied patients. HCV RNA titres, measured by quantitative PCR, were significantly higher in HIV-positive patients compared with HIV-negative patients (P < 0.05) but were not related to HAI, mean factor concentrate usage, duration of HCV infection or HCV genotype. There was no relationship between HCV genotype and HAI. Qualitative HCV PCR was positive in 30 of 43 liver biopsies tested. Biopsy PCR-positive and -negative cohorts were not distinguished by HAI or serum HCV titre. We conclude that although serum HCV PCR is useful in confirming the presence of HCV infection in patients with bleeding disorders, little meaningful information concerning the severity of the disease can be obtained from serum HCV quantification.

Abstract
BACKGROUND/AIM This retrospective study aimed to better define the respective biological and pathological impact of human immunodeficiency virus infection and chronic alcohol consumption on the course of hepatitis C virus infection in intravenous drug users. METHODS Two hundred and ten consecutive anti-HCV positive intravenous drug users, among whom 60 were also anti-HIV positive, took part in the study at the University Hospital, Paris, France. RESULTS The activity of aspartate aminotransferase and gamma-glutamyl transpeptidase was significantly increased in serum from anti-HIV positive patients. The mean hepatitis activity index was significantly higher in anti-HIV positive patients (p<0.05), among whom there was also a higher proportion of patients with cirrhosis as compared to anti-HIV negative patients (30.0 vs 15.3%, p<0.0001). Excessive alcohol drinking (recorded in around 35% of the patients, whatever their HIV status), as compared to non-excessive drinking, was more often associated with cirrhosis in anti-HIV negative (24.5 vs 11.3%, p<0.05) than in anti-HIV positive patients (30.4 vs 29.7%, not significant). In a multivariate analysis, HIV infection (relative risk 2.2, confidence interval 1.1-4.5) and excessive alcohol drinking (relative risk 1.9, confidence interval 1.0-3.9) were the variables independently associated with the risk of cirrhosis. CONCLUSION Human immunodeficiency virus infection worsens the course of chronic hepatitis C in intravenous drug users. Excessive alcohol drinking also appears to be a crucial negative cofactor, and therefore alcohol withdrawal should be proposed as an integral part of the therapy.

Abstract
The world-wide prevalence of hepatitis C virus (HCV) is approximately 1%. Being primarily a blood-borne virus, the major risk factors for HCV include the receipt of blood and blood products, as well as intravenous drug use. As a result, many individuals infected with HIV are also infected with HCV. Any effect of coinfection on progression of either HIV or HCV is likely to have a tremendous impact on the mortality and morbidity of these individuals and should be considered when managing coinfected individuals. This review will describe the epidemiology and clinical manifestations of HCV and will consider the evidence for an impact of coinfection on the progression of both viruses.

Abstract
We examined 41 Turkish children with haemophilia for evidence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections using the enzyme-linked immunosorbent assay (ELISA). Hepatitis B surface antigen was found to be positive in 11 patients (26.8%) and HCV-specific antibody (anti-HCV) was detected in 10 (24.4%) patients. There was a close relationship of the number of transfusions of blood plasma to the presence of HCV specific antibody, but not to the serum markers of HBV infection. In countries where HBV infection is commonly seen and problems in transfusion practice continue, as in Turkey, children with haemophilia are at greater risk for HBV and HCV infections.

Abstract
Twenty-one HIV negative Japanese patients with chronic hepatitis C who had congenital bleeding disorders, 15 hemophilia A, 3 hemophilia B, 1 von Willebrand's disease, 1 afibrinogenemia and 1 thrombasthenia, were treated with 9 million units 3 times a week of natural interferon (IFN)-alpha for 6 months. They were followed, biochemically and virologically, for at least 18 months after therapy discontinuation to evaluate the long-term results. Liver biopsy, hepatitis C virus (HCV) genotyping and quantification of viral load by polymerase chain reaction (PCR) were performed to identify the predictors of a favorable response to IFN treatment. One male patient with hemophilia A dropped out because of general fatigue and was excluded from evaluation. Ten (50.0%) patients continued to be HCV RNA negative in serum together with normal ALT levels throughout the study. Subtype 1b and a high level of viremia significantly associated with an unfavorable outcome on the response to IFN although liver histology was not definitive for predicting the response. We concluded that a 6-month treatment with high doses of natural IFN-alpha was effective in inducing a long-term response without relapse of viremia in 50% of chronic hepatitis C patients with congenital bleeding disorders and that HCV subtype and pretreatment level of viremia were useful predictors of the response to IFN in treating such patients.

Abstract
The natural history of hepatitis C is complex and still poorly known. Hepatitis C virus (HCV) replication can be detected very soon after exposure and, at least in the transfusional setting, it persists indefinitely in up to 90% of the cases. While liver damage during the acute phase of hepatitis is almost invariably mild (fulminant cases are exceptions), chronic sequelae of HCV infection may be severe in the long run. Chronic hepatitis C, in fact, is a long-lasting indolent process which leads to cirrhosis in approximately 20% of all infected patients. Hepatocellular carcinoma is a well-recognized complication of old infections, as are a number of extrahepatic manifestations, including type II cryoglobulinaemia. The determinants of the severity of the liver disease are still unclear. However, the risk of cirrhosis seems to be greater for patients with old infections, those infected with the genotype 1b and those with associated conditions. The latter are a heterogeneous and increasing group of 'problem' patients, including patients who are co-infected with the human immunodeficiency virus (HIV1), or who are being treated with cytotoxic or immunomodulating drugs. Data suggest that the natural history of hepatitis C is altered in patients with associated conditions, and this might have an impact on strategies of patient management and treatment.

Abstract
A 14-year follow-up of 153 haemophilic patients treated with clotted factor concentrates was made to assess liver function. Investigations included measurement of alanine amino transferase (ALT), immunoglobulins, HIV antibody, HBsAg, antibody to HBs and HBc antigens, antibodies to HCV (assayed by ELISA-2 and by RIBA-2) and HCV viraemia assessed by PCR. Assessment of liver function also included liver ultrasound scan and oesophageal X-ray. A positive correlation was found between abnormal liver function and age, HIV infection, HBV infection, HCV infection and hepatomegaly. However, there was no correlation between abnormal liver function and annual clotting factor concentrate use. The increasing incidence of liver insufficiency with increasing age is likely to result in substantial morbidity and mortality amongst haemophilic patients.

Abstract
The authors describe a young man with hemophilia complicated by chronic hepatic dysfunction, hypodysfibrinogenemia, and immune thrombocytopenia that resulted in a complex coagulopathy. The patient had a ruptured occipital arteriovenous malformation. The malformation was managed by temporary correction of the coagulopathy using cryoprecipitate, platelet transfusions, and plasmapheresis with fresh frozen plasma replacement. The patient underwent staged preoperative embolization followed by surgical excision of the lesion. Hemostasis was acceptable during the neurointerventional and subsequent surgical management, and no complications of coagulopathy occurred. Plasmapheresis may provide effective preparation for patients with hemophilia and complex coagulation abnormalities who require neurosurgical intervention.

Abstract
We have studied morbidity and mortality related to hepatitis C virus infection in haemophilic patients treated at our centre. 11/255 HCV seropositive patients have developed hepatic decompensation. 20 years after first exposure to lyophilized clotting factor concentrate the risk of hepatic decompensation is estimated to be 10.8% (95% CI 3.8-17.8%). There is a significantly increased risk associated with HIV infection, and also with increased age. For HIV seropositive patients the rates of decline in CD4 lymphocyte count and the development of p24 antigenaemia are significant risk factors for hepatic decompensation. Cirrhosis was seen in 9/19 HIV seropositive patients at post mortem. There was an association of cirrhosis with increased age but not with CD4 count, p24 antigenaemia, or AIDS. In conclusion, HCV infection is associated with serious liver disease in haemophilic patients, but so far this has been restricted to a minority of those at risk. HIV co-infection accelerates progression to hepatic decompensation, and we speculate that this is probably due to enhanced HCV replication in the presence of immune deficiency.

Abstract
Thirteen patients with congenital coagulation disorders and chronic hepatitis C were treated with alpha-interferon (IFN). Serum transaminases (ALT) and hepatitis C virus (HCV)-RNA in plasma and peripheral blood mononuclear cells (PBMC) were followed during and after treatment. During IFN treatment ALT levels normalized in 8/13 patients. In all patients HCV-RNA disappeared from PBMC. In 9/13 HCV-RNA also became undetectable from plasma; in six of these nine this occurred earlier in PBMC than in plasma; in the remaining three the disappearance of HCV-RNA occurred simultaneously in plasma and PBMC. All but two patients relapsed within 3 weeks after cessation of IFN, one relapsed after 6 weeks and one patient remains in remission after 6 months. HCV-RNA reappeared either earlier in plasma (3/12) or simultaneously in plasma and PBMC (9/12). Viral replication in PBMC thus can easily be suppressed by IFN, whereas longer treatment is needed for the eradication of HCV-RNA in plasma. The detection of HCV-RNA in PBMC cannot be used as a prognostic marker for the identification of patients with chronic hepatitis C who will have a sustained response to IFN treatment.

Abstract
To examine recent changes in longevity and the causes of death among persons with hemophilia A, we evaluated death certificate data for persons who died in the United States from 1968 through 1989 and had hemophilia A or congenital Factor VIII disorder (ICD code 286.0) listed on the death certificate as one of the multiple causes of death. Multiple-cause-of-death mortality data for the United States from 1968 to 1989 were examined to compare death rates by year, focusing on death rates and causes of death for 1979-1981, 1983-1985, and 1987-1989. Gender, age group, race, geographic region, and median age at death of persons with hemophilia A and human immunodeficiency virus (HIV)-related disease listed as a cause of death were compared with those with hemophilia A without HIV-related disease. From 1968 through 1989, 2,792 hemophilia A deaths were reported. The death rate increased from 0.5 to 1.3 per 1,000,000 persons. From 1979-1981 through 1987-1989, mortality increased in all age groups above 9 years of age and age at death shifted markedly to lower ages. Median age at death decreased from 57 years in 1979-1981 to 40 years in 1987-1989. The percentage of deaths due to hemorrhage or diseases of the circulatory system decreased markedly as the result of the increase in deaths associated with HIV infection or infections other than HIV infection. Spread of HIV-1 infection in persons with hemophilia A has disrupted the reduction in mortality seen with factor replacement therapy, implementation of home care, and use of comprehensive hemophilia treatment centers. It is hoped that advances in the care of HIV-infected persons will improve survival in the hemophilia community.

Abstract
Chronic hepatitis affects almost all haemophiliacs treated with non-virally inactivated clotting factor concentrates. The virus responsible is hepatitis C (HCV) and most patients have non-neutralising antibodies with circulating virus. Although the majority also have evidence of past infection with hepatitis B, less than 5% are chronic carriers of HBsAg. Chronic hepatitis C can be associated with severe and progressive liver disease but the development of complications is slow. Treatment with recombinant interferon alpha given subcutaneously normalises the liver function in 50% of patients, but 50% of responders relapse on stopping treatment. Liver transplantation is successful in patients with advanced liver disease and it offers the added advantage of phenotypic cure of the haemophilic state.

Abstract
The hepatitis C virus (HCV) has been cloned, and assays capable of detecting antibody to HCV recombinant proteins (anti-HCV) have been developed. Concurrent with the cloning and development of the anti-HCV screening tests, trials with interferon alfa-2b have documented biochemical and histologic improvement in the indices of hepatitis C and non-A, non-B (NANB) in patients who were chronically infected. Subsequently, the anti-HCV assays and interferon alfa-2b have become clinically available. These new detection and treatment modalities can now be used in the management of hemophilics and other chronically transfused patients who bear great risk for blood-borne infections and manifest signs of chronic hepatitis.

Abstract
One hundred and thirty-five patients who developed non-A, non-B post-transfusion hepatitis mostly after cardiac surgery, were followed for a mean (+/- S.D.) of 90 +/- 41 months (range: 13-180) to evaluate clinical and histological outcome. Thirty-one cases resolved within 12 months, while 104 (77%) progressed to chronicity. Twenty-one of 65 (32%) biopsied patients developed cirrhosis at the end of the follow-up, and one further progressed to hepatocellular carcinoma. One patient had a complete histological remission (1%). The remaining cases had chronic active (37%), chronic persistent (27%) or chronic lobular hepatitis (3%). About half of the cases with cirrhosis developed portal hypertension, and three of these died due to esophageal varices hemorrhage, one due to liver failure, and one due to hepatocellular carcinoma. Out of 26 patients with the initial histologic diagnosis of chronic hepatitis that were rebiopsied during follow-up, 13 (50%) progressed to cirrhosis. These patients were significantly older than patients who did not develop cirrhosis (mean age 57 and 45 years respectively; p < 0.01). During acute hepatitis anti-HCV was positive in all but one of the 114 patients tested. Percentages were similar for patients who recovered (95%) and those who developed chronic hepatitis (100%). However, during follow-up, 71% of the 1st generation and 21% of the 2nd generation ELISA test patients with acute resolved hepatitis became anti-HCV negative, while the same figures in chronic cases were only 8.5% (p < 0.0001) and 1.4% (p = 0.012). This suggests a correlation between anti-HCV antibody activity, hepatitis C virus replication, and the development of chronic liver disease.

Abstract
The antibody responses and the prevalence patterns of antibodies to hepatitis C virus (anti-HCV) in a cohort of patients (n = 210) with bleeding disorders were studied using a first-generation and a second-generation enzyme immunoassays (EIA-1, EIA-2) as well as a second-generation recombinant immunoblot assay (RIBA-2). The anti-HCV prevalence as determined by EIA-1 and EIA-2 was 183/210 (87.1%) and 197/210 (93.8%), respectively (p = 0.0026). None of the 17 EIA-2(+)/EIA-1(-) samples was scored nonreactive by RIBA-2. At follow-up, samples of 123 patients were tested. Twenty-nine out of 111 patients reactive by EIA-1 seroreverted according to EIA-1 while the seroreversion rate with EIA-2 was 0 out of the 121 (p < 10(-8)). The anti-HCV prevalence by EIA-2 was 150/154 (97.4%) in anti-HIV-1-positive individuals and 47/56 (83.9%) in the anti-HIV-1-negative ones (p = 0.001). However, high assay signals (OD 492 nm > 2.0) were observed in 94/150 (62.7%) and 45/47 (95.7%) of the anti-HIV-1-positive and -negative patients, respectively (p = 10(-5)). The decreasing anti-HCV reactivity among anti-HIV-1-positive individuals was mainly due to diminishing c33c reactivity. Seroconversion to anti-HCV was observed in 3/7 (42.9%) cases with acute icteric non-A, non-B hepatitis by both EIA-1 and EIA-2, while the remaining 4 cases had detectable levels of anti-HCV 1-18 months before the acute episode.

Abstract
10 years ago, it became apparent that haemophiliacs were developing diseases which were indicative of underlying immunodeficiency. The results of investigation confirmed that many had abnormal immune systems, particularly with regard to cell-mediated immunity. These abnormalities were thought to be a consequence of the use of clotting factor concentrates, and indeed the discovery of HIV and its mode of transmission, confirmed these suspicions. However, it subsequently became clear that HIV infection did not explain all the abnormalities observed. Many in vivo studies have shown that the immune systems of HIV-negative haemophiliacs are not entirely normal, and in vitro studies have shown that clotting factor concentrates per se have a modulating effect on immune function. We have reviewed particularly the abnormalities seen in HIV-negative haemophiliacs and their possible causes, as well as the specific features of HIV infection in haemophiliacs.

Abstract
All reported studies to date, whether comparative or not, have shown a tendency toward a slower decrease in CD4+ numbers in patients receiving very high-purity agents with the rapidity in fall-off being affected by level of CD4+ numbers (low CD4+ numbers decreasing more rapidly), age (older persons showing more rapid CD4+ cell fall-off), and anti-HIV therapy. Clearly, these observations need to be extended in numbers, and the high-purity agents should also be similarly compared with the very high-purity therapies.

Abstract
The prevalence of antibodies to hepatitis C virus (anti-HCV) was studied in various population subsets in the Netherlands with anti-HCV C100 enzyme linked immunosorbent assay (ELISA), and confirmed with recombinant immunoblot assay (RIBA). Anti-HCV C100 ELISA positivity and RIBA positivity were found in 39 (0.7%) and 5 (0.1%) of 5,434 blood donors from Amsterdam; 25 (5%) and 2 (0.4%) of 481 blood donors from Surinam (South America); 19 (9%) and 2 (1%) of 213 multitransfused patients; 28 (4%) and 15 (2%) of 633 hemodialysis patients; 179 (80%) and 150 (67%) of 225 hemophilia A and B patients; 8 (80%) and 4 (40%) of 10 intravenous drug abusers; 18 (15%) and 2 (2%) of 119 anti-HIV-positive homosexual men; 2 (2%) and none of 106 anti-HIV-negative homosexual men; 6 (32%) and 3 (16%) of 19 patients with acute hepatitis non-A, non-B (NANBH); 13 (65%) and 8 (40%) of 20 patients with chronic NANBH and/or cryptogenic cirrhosis; and 4 (40%) and 1 (10%) of 10 patients with idiopathic autoimmune chronic hepatitis. Among blood donors, a positive correlation between a history of jaundice after the age of 18 years and the presence of RIBA-confirmed anti-HCV antibodies was found. Among both blood donors and hemodialysis patients, a positive correlation of RIBA-confirmed anti-HCV positivity with elevated alanine aminotransferase levels, but not with the presence of anti-hepatitis B core antibodies was found.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A questionnaire-based survey involving 11,801 hemophiliacs from 54 hemophilia centers in the USA and Europe documented the occurrence of hepatocellular carcinoma (HCC) in 10 patients. The crude rate of HCC was 3.2/100,000 patients/year, at least 30 times higher than the background incidence of this tumor in the countries of origin of the patients. All patients were Caucasians with hemophilia A, 39 to 74 years of age, and had liver cirrhosis. All had one or more risk factor for cirrhosis and HCC: 5 were positive for serum hepatitis B surface antigen, 4 had the antibody to hepatitis C virus, and 4 had histories of alcohol abuse. Serum alpha-fetoprotein, measured in 6 patients, was significantly elevated in 4 (range: 807-1399 ng/ml), and only moderately elevated in 2 (25 and 171 ng/ml). The onset of HCC was asymptomatic in 5 patients, whereas it was accompanied by jaundice, abdominal pain, or ascites in the remaining patients. Thus, HCC seems to be a more important secondary disease for hemophiliacs than formerly recognized. Since HCC is often asymptomatic, screening hemophiliacs with chronic liver disease with periodic ultrasound scans might increase the changes of detecting HCC at a stage amenable to surgical treatment.

Abstract
Lane (1840) first noted the beneficial effect of blood transfusion in controlling haemophilic bleeding following ophthalmic surgery. The appreciation that haemophilia is due to a plasma defect, at first thought to be prothrombin, coincided with the discovery of blood groups. This led in due course to the discovery of citrate anti-coagulant and the ability to store blood. The beneficial effect of citrated plasma in haemophilia led to the exploitation of stored blood, fresh frozen plasma, and the subsequent development of cryoprecipitate and factor concentrates. All this would not have been possible, however, without the selfless contribution of blood donors and the development of an organized blood transfusion service. In the United Kingdom, P. L. Oliver pioneered the development of blood donor panels, the London Blood Transfusion Service and the British Red Cross Society Blood Transfusion Service leading directly to the National Blood Transfusion Service; recognized as the World's senior service. The development of haemophilia therapy owes much, therefore, to Oliver's energetic and pioneering work and it is entirely appropriate that the first Oliver Memorial Lecture be directed to the evolution and future of haemophilia therapy. It is indeed an honour to be invited to deliver this Oliver Memorial Lecture at the combined meeting of the British Blood Transfusion Society and the British Society for Haematology here in Wembley.

Abstract
Parenterally transmitted non-A, non-B (NANB) hepatitis virus or hepatitis C virus is a common cause of both acute and chronic hepatitis. Using a recently developed enzyme-linked immunosorbent assay we looked at the prevalence of antibodies to hepatis C virus (anti-HCV) in a number of groups. People with haemophilia (75.6%) and intravenous drug users (61.9%) had the highest prevalence, while homosexual men attending a sauna (34.1%) and prisoners (30.8%) had a moderately high prevalence of anti-HCV. A lower prevalence of antibody was detected in female prostitutes (10.4%), institutionalised mentally retarded subjects (9.5%), homosexual men requesting human immunodeficiency virus (HIV) testing through their local doctor (8.8%), dialysis patients (5.9%), renal transplant patients (6.9%), and patients referred from a sexually transmitted diseases clinic (6.2%). The lowest prevalence of anti-HCV was recorded in women attending a provincial hospital for antenatal care (0.4%). The predominance of anti-HCV in groups of people exposed to blood-borne and sexually transmitted infections suggests that these routes may be primarily involved in the spread of hepatitis C virus infection.

Abstract
A radioimmunoassay was used to detect antibodies to hepatitis C virus (anti-HCV) in 154 patients with haemophilia. Prevalence of anti-HCV was associated with exposure to clotting factor concentrates. 76 of 129 (59%) who had received factor VIII or IX had anti-HCV: 42 of 55 (76%) who required over 10,000 units of concentrate annually had anti-HCV, compared with 34 of 74 (46%) who required less, and 0 of 25 patients who had never received concentrates. Anti-HCV were significantly more common in patients seropositive for antibodies against human immunodeficiency virus (anti-HIV) or with markers of previous hepatitis B infection than in those without anti-HIV or hepatitis B markers (88% vs 39% and 75% vs 46%, respectively). 5 of 23 (22%) haemophiliacs treated only with heated concentrates had anti-HCV compared with 71 of 106 (67%) patients who received unmodified products. 35 patients with chronic liver disease underwent liver biopsy: histological examination showed features associated with post-transfusion hepatitis in 24, all of whom were anti-HCV-positive; of the other 11 patients with no histological features of non-A, non-B hepatitis, 5 were anti-HCV-positive. HCV appears to be the major predisposing factor for most non-A, non-B hepatitis and chronic liver disease in haemophilia.

Abstract
Guidelines have been prepared by the National Hemophilia Foundation, USA, for treating patients with haemophilia, these are: 1. General recommendations. The risks of withholding treatment far outweigh risks of treatment. Patients should however be educated to use appropriate clotting factor doses to minimize overuse and contain costs. 2. Factor VIIIC-deficient patients. DDAVP should be used whenever possible by patients with mild or moderate factor VIIIC deficiency. When feasible, an alternative to concentrates may be the use of cryo-precipitate prepared from one well-screened donor or from a small number of such donors. (a) Prevention of hepatitis. Hepatitis B vaccination is essential for uninfected patients. Preliminary data suggest that products that are pasteurized, solvent/detergent-treated or monoclonal antibody-purified are at a reduced risk of transmitting hepatitis viruses. (b) Prevention of HIV-1. Concentrates pasteurized, treated with solvent/detergent, purified with monoclonal antibody, heated in suspension with organic solvents, or dry heat-treated for long periods are preferred. These products carry a substantially reduced risk of transmitting HIV-1. 3. Factor IX deficiency. For patients with severe deficiency the use of virus-inactivated Factor IX concentrate is recommended. For mild to moderate patients when feasible an alternative would be fresh, frozen plasma prepared from one well-screened and repeatedly-tested donor or from a small number of such donors. In the past few years, significant progress has been made in understanding the nature of the defect in haemophilia both at the molecular and structural levels, such a foundation is necessary for definitive treatments in the future. For now, however, the dark side of replacement therapy must be accepted along with its benefits.

Abstract
No information is available on the role of non-A, non-B hepatitis in the various hepatic abnormalities described in patients with the acquired immune deficiency syndrome. Of 97 patients referred with suspected non-A, non-B hepatitis, 3 were found to have antibody to the human immunodeficiency virus. These latter 3 patients all developed symptomatic cirrhosis within 3 yr of onset of hepatitis. Such a rapid progression of liver disease was rare in patients with non-A, non-B hepatitis who did not have simultaneous human immunodeficiency infection. These findings suggest that human immunodeficiency virus infection may potentiate the liver injury of chronic non-A, non-B hepatitis.
