A case of disseminated Kaposi's sarcoma (KS) in a 21-yr-old white heterosexual male with cryptogenic cirrhosis and no serological or immunological evidence of acquired immune deficiency syndrome (AIDS) is reported. The patient died 2 wk after diagnosis. Postmortem examination showed involvement of lymph nodes, liver, spleen, gastrointestinal tract, and bone marrow. This case demonstrates that Kaposi's sarcoma can occur in a young heterosexual male with normal immune function and in the absence of HIV infection.

Infections with the B, D, A, NANB viruses and with the human immunodeficiency virus (HIV) are very common among drug addicts, some of whom may harbour several of these pathogens. The serum of 90 per cent of drug addicts contains one of the HBV markers, and 20 per cent of them carry an anti-D antibody which is more often present in HBs Ag-positive subjects but may also be found in those who are positive for anti-HBs and anti HBc antibodies. The presence of an anti-delta antibody increases the risk of severe histological lesions (chronic active hepatitis, cirrhosis), as does chronic alcoholism associated with drug addiction. Fifty to sixty per cent of drug addicts are seropositive for HIV. At the AIDS stage, hepatic lesions are extremely frequent (90 per cent), but they have low activity and are seldom responsible for death.

We describe a 78-year-old man with a diffuse large-cell lymphoma that was limited to the liver and was associated with micronodular cirrhosis and Kaposi's sarcoma that involved abdominal lymph nodes and gastric mucosa. The serum of the patient reacted positively to a test for human T-cell lymphotropic virus type III antibodies. We discuss the clinical and autopsy findings for this unusual patient, the criteria for the diagnosis of primary lymphoma of the liver, and its occurrence in patients with the acquired immunodeficiency syndrome.

Liver disease, although usually asymptomatic, is a frequent accompaniment of AIDS. Hepatomegaly and macrosteatosis are prevalent but non-specific findings. Evidence of remote hepatitis B virus infection is extremely common; however, the HBsAg carrier state, chronic active hepatitis, or cirrhosis occur no more frequently in AIDS patients than in the general population. Opportunistic intrahepatic infections (such as MAI, fungi, and CMV) or neoplasms (such as lymphoma or KS) usually reflect a disseminated process; liver involvement generally does not directly cause morbidity or result in death. Although biochemical liver tests are commonly elevated in the AIDS population, alkaline phosphatase has proved to be the most specific enzyme for infiltrative processes. Percutaneous liver biopsy has a high diagnostic yield, although the treatment options are currently limited. Acalculous cholecystitis and biliary tract obstruction have been recently described and probably result from CMV and/or cryptosporidial infection. Radiologic features of papillary stenosis and/or sclerosing cholangitis have been demonstrated. In contrast to hepatic parenchymal disease, these entities may be amenable to surgical or endoscopic therapeutic maneuvers.

Accurate classification of clinical severity is important for interpreting casemix in clinical studies and for stratifying patients for clinical trials. To evaluate whether clinical judgment might be an effective method of estimating severity, all 604 patients admitted to the medical service in a one month period were rated at the time of admission by the responsible resident as to how sick they were. Within the 13 comorbid disease groups, and within the 15 basic categories of reason for admission, the physicians' severity ratings were the most significant predictor of in-hospital mortality. Death rates rose from 0% in those rated as not ill, to 2% in the mildly ill, to 6% in the moderately ill, to 23% in the severely ill, and to 58% in those rated as moribund (p less than 0.001). Sickness ratings also predicted time to death: mildly ill patients died after prolonged hospitalizations, while the moribund died shortly after admission. The patients' age, sex, race, the number of comorbid diseases or problems did not predict mortality. Patients with serious comorbidity (metastases, AIDS, or cirrhosis) had a higher mortality rate than other patients (p less than 0.001); however, the severity ratings predicted outcomes within this group (p less than 0.001) as well as among those without such serious comorbidity (p less than 0.001). Patients who were admitted with acute neurologic (p less than 0.05) or acute cardiovascular (p less than 0.01) events did have an independently worse prognosis. In conclusion, physicians' estimates or sickness provided an accurate estimate of illness severity, with mortality rates that essentially tripled from one stratum to the next. Clinical judgment may suffice to classify the clinical severity of patients at the time of enrollment in prospective trials and can provide a useful method of controlling for casemix.

At a time when the acquired immunodeficiency syndrome as well as hepatitis and other blood-borne diseases are a threat to patients with bleeding disorders who need treatment with blood products, it is rewarding to realize that a number of these patients can be safely and effectively treated with their own desmopressin-stimulated F.VIII:C and vWF. Desmopressin is clinically useful for treatment of patients with moderate and mild hemophilia. The limits of the clinical indications are established by the nature of the bleeding episode, the resting factor level, the level that must be achieved, and the length of time the level must be maintained to manage any given bleeding episode. In von Willebrand disease, desmopressin can be used more extensively to raise F.VIII:C levels than in classic hemophilia, because fewer of the patients have the severe form of the disease that is unresponsive to desmopressin. Increases in the level of F.VIII:C of about four times the resting value can be expected both in hemophilia and von Willebrand disease, but it must be borne in mind that the range of individual responses is large. Even though it is not easy to correct the prolonged bleeding time, particularly in patients with dysfunctional vWF, this drawback is of clinical relevance only in a minority of cases. A role for the use of desmopressin in acquired diseases of primary hemostasis has been proposed more recently, and experience is more limited than in congenital bleeding disorders. Uremia is probably the most firmly established indication because it has been shown that the bleeding time is often dramatically shortened by desmopressin, and hemorrhages can be stopped or prevented before surgical procedures. The indications for use of the compound in liver cirrhosis and congenital and acquired platelet dysfunctions are promising but much less established from a clinical standpoint. The bulk of available clinical experience is based on intravenous administration. Intranasal and subcutaneous administration have been successfully attempted and might be more convenient in selected circumstances, such as home treatment and the stimulation of blood donors to provide more abundant supplies of F.VIII:C and vWF. However, the responses after intranasal administration are less predictable and consistent than after intravenous administration. Desmopressin has few troublesome side-effects. Mild facial flushing, a small increase in heart rate, and, more rarely, mild headache can occur transiently during infusion. Signs of hyponatremia or cerebral edema are extremely rare, providing that excessive fluid intake is avoided.(ABSTRACT TRUNCATED AT 400 WORDS)

In an attempt to predict progressive liver damage in hemophiliac patients by noninvasive means, we conducted a retrospective analysis of clinical and laboratory data from 44 liver biopsies taken from 35 hemophiliac patients. This showed that serum IgG was normal in patients with chronic persistent hepatitis (CPH) but significantly elevated in those with chronic active hepatitis (CAH) or cirrhosis (CIR) (P less than .001). Relationships were less significant between liver histology and IgM (P less than .01), IgA (P less than .05), and globulin (P less than .05). This was unaffected by human immunodeficiency virus (HIV) antibody status in asymptomatic individuals. Although patients with progressive liver disease were also older than those with CPH (P less than .001), the immunoglobulin abnormalities were independent of this. Neither clinical examination nor liver biochemistry at the time of biopsy were of significant diagnostic value. Our results indicate that in the absence of AIDS an elevated IgG level is a reliable indicator of progressive hemophilic liver disease.

At this time, when the acquired immunodeficiency syndrome, hepatitis, and other blood-borne diseases threaten patients, with bleeding disorders, who need treatment with blood products, it is rewarding to realize that a number of them can be safely and effectively treated through the stimulation of their own VIII:C and vWF production with desmopressin. Desmopressin is clinically useful for treatment of patients with moderate and mild hemophilia. The limits of the clinical indications are the nature of the bleeding episode, the resting factor level, the level that must be achieved, and the length of time the level must be maintained to manage any given bleeding episode. Desmopressin can be used more extensively to raise VIII:C in von Willebrand's disease, than in classic hemophilia, because fewer of the patients have the severe form of the disease that is unresponsive to desmopressin. VIII:C increases to about four times the resting values that can be expected in both hemophilia and von Willebrand's disease, but it must be kept in mind that the range of individual responses is large. Even though it is not easy to correct the prolonged bleeding time, particularly in patients with dysfunctional vWF, this drawback is of clinical importance for only a minority of cases. Use of desmopressin in acquired diseases of primary hemostasis has been proposed more recently, and our experience is more limited than for congenital bleeding disorders. Uremia is probably the most firmly established indication, because the bleeding time is often dramatically shortened by desmopressin, and hemorrhages can be stopped or prevented. The indications for the compound in liver cirrhosis and congenital and acquired platelet dysfunctions are promising but much less well-established. The mechanism of action of desmopressin is not well-known, and more work must be done to fill this important gap. This problem is not only of theoretical importance, because understanding of the mechanism of action of the compound should open up new perspectives into understanding the physiological mechanisms that regulate hemostasis. Many unclarified aspects of the mechanism of desmopressin action might be elucidated by using specific antagonists and also by using appropriate animal models. (Dogs and primates respond partially to desmopressin, but rats and rabbits do not respond at all).(ABSTRACT TRUNCATED AT 400 WORDS)

The CDC estimates that about 200,000 Americans become infected with HBV each year. About 200 die of fulminant hepatitis. Most importantly, 12,000 to 20,000 persons become chronically infected, placing themselves at increased risk of developing chronic sequelae such as cirrhosis and primary hepatocellular carcinoma and also putting their families and close personal contacts at risk of hepatitis B infection. An effective vaccine to protect against hepatitis B is currently available. The vaccine is produced according to a rigorous process known to kill HBV, the agent causing AIDS, and all other viruses known to be present in human plasma. Well-controlled clinical studies have shown the vaccine to be well tolerated, immunogenic, and highly effective in preventing hepatitis B. The benefits of vaccination are clear.

Clinical and autopsy findings obtained from 15 male patients treated for acquired immunodeficiency syndrome (AIDS) at 3 hospitals in Sao Paulo provided a clearer profile of AIDS cases in Brazil. Of the 12 patients whose sexual orientation was recorded, 9 were homosexual and 3 were bisexual. 75% were between the ages of 22-36 years; 14 were white. The duration of diseases ranged from 14 days-7 months in this series, confirming the rapid evolution of AIDS from 1st symptom to death. The most common clinical manifestations of disease were fever, cough, weight loss, diarrhea, and lymphadenopathy. Organs most frequently involved were the lungs (13 cases) and encephalum (9 cases). Microscopic findings revealed 9 types of microorganisms, fungi, and protozoa, the most common of which was Cytomegalovirus (7 cases). The cause of death was meningoencephalitis in 7 cases and panlobar pneumonia in 3 cases. The incidence of Kaposi's sarcoma (2 cases) was surprisingly low in this series. In addition to lesions produced by microorganisms, there were important associated lesions represented by lymphocytic depletion, acute myocarditis, brown atrophy of neuronia, acute pancreatitis, and liver cirrhosis. Several microorganisms and tumors in these AIDS patients were discovered only at autopsy, confirming the importance of necropsy to the study of the natural history of this disease. An unexpected pathological finding in this series was the absence of cellular reactions to microorganisms, particularly Pneumocystis carinii, Cryptococcus neoformans, and Mycobacterium tuberculosis.
