Most causes of abnormal bleeding can be determined from a complete blood count including platelet count and bleeding, prothrombin, activated partial thromboplastin, and thrombin times. Occasionally, further evaluation is necessary, such as tests of factor XIII function, fibrinolysis, and vascular integrity. Possible diagnoses include disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, vitamin K deficiency, von Willebrand's disease, heparin-induced thrombocytopenia, acquired inhibitors of factor VIII, lupus anticoagulants, and coagulation disorders related to the acquired immunodeficiency syndrome.

A retrospective study of all patients with systemic lupus erythematosus (SLE) who died at the University Hospital of the West Indies over a 14-year period is presented. The major cause of death was infection followed by renal failure. Gram-negative organisms were the major microbiological agents causing infections. Side-effects of therapy were common, in particular bone marrow depression and haemorrhage related to anticoagulants. It appears that controlling severe lupus activity without increasing the risk of lifethreatening complications remains an important goal in the treatment of SLE.

The 5'-terminal noncoding region sequences were determined for the genome RNAs of seven strains of St. Louis encephalitis virus (SLEV) and one strain of West Nile virus (WNV) using a single synthetic cDNA primer complementary to the 5'-terminus of the coding region of a strain of WNV RNA. The 5'-terminal sequences obtained for the SLEV and WNV RNAs were compared with published sequences for yellow fever virus (YFV), Murray Valley encephalitis virus (MVEV), and dengue virus. While only short regions within the 5'-noncoding sequence were conserved among different flavivirus RNAs, significant homology was observed in this region among members of the same flavivirus subgroup and almost complete conservation was observed between different strains of the same virus. For example, seven strains of SLE, isolated from different geographic locations over a 17-year period and differing in their neurovirulence phenotype, contained only two to four nucleotide changes in the 5'-noncoding region. Interestingly, each of three low-virulence strains shared the same unique base substitution at position 16. Secondary structures predicted to be formed by the 5'-termini of each of the different flavivirus genome RNAs were of similar size and shape, in each case consisting of a stem with a small top loop and a larger side loop. The prediction of a common structure among a number of different flaviviruses, despite the lack of extensive sequence homology, suggests that this secondary structure is functionally important. An additional stem and loop structure is predicted to be formed in the region spanning the translation initiation codon. This structure showed significantly less conservation of size and shape than the 5'-terminal secondary structure.

Systemic lupus erythematosus (SLE) has been found in all ethnic groups, but some of these groups--notably the black populations of the United States--seem to develop severe forms of the disease. We compared the signs and course of SLE in 20 black patients from the French West Indies, 20 patients of North African origin and 40 European Caucasians. At the onset of the disease, most of the West Indian and North African patients were living in France, and their social level was similar to that of the European patients. On the whole, our study confirmed that SLE is particularly severe in black populations. This severity is primarily due to renal involvement: 7 of the 13 renal biopsies we performed showed diffuse proliferative glomerulonephritis. In North African patients the severity of SLE was intermediate between that observed in West Indians and in European Caucasians. Five out of our 40 West Indian and North African patients died, as against only one female patient among the 40 European Caucasians. These differences seem to be ascribable to genetic factors rather than to environmental factors.

Sm antigen was purified by immunoaffinity chromatography using a murine monoclonal anti-Sm antibody and was confirmed to be free from contaminating polypeptides. This was then used to detect anti-Sm antibodies in patients' sera by enzyme linked immunosorbent assay (ELISA). Antibodies against Sm were detected in only 9/52 (17%) patients with systemic lupus erythematosus (SLE) by immunodiffusion, but 15/52 (29%) were positive for IgG anti-Sm antibodies by ELISA. The presence of anti-Sm antibodies remained disease specific despite the increase in sensitivity of this assay and validates its potential use for clinical application. There was no correlation between the presence of anti-Sm antibodies and any clinical features of SLE. In 23 renal biopsies a membranous component to the glomerulonephritis correlated with anti-Sm antibodies (p less than 0.05). Patients from West Africa, the Carribean Islands, and Asia had a higher prevalence of anti-Sm antibodies than the local Caucasian population.

To determine whether systemic lupus erythematosus (SLE) is associated with human T-lymphotropic virus, type I (HTLV-I) infection in Jamaica, an endemic area for the virus, we studied 63 patients with SLE at the University Hospital of the West Indies in Kingston. Antibodies to HTLV-I were measured by an enzyme-linked immunosorbent assay (ELISA) technique using purified disrupted whole virus as antigen, with confirmation by p24 protein RIA or competitive binding. Four of 63 SLE patients were HTLV-I seropositive (6.3%). There was no evidence for excess HTLV-I infection in SLE patients when their age- and sex-standardized HTLV-I seroprevalence rate was compared to that of a large group of healthy food service employees. None of 13 patients with rheumatoid arthritis were seropositive for HTLV-I. We conclude that HTLV-I infection does not appear to be linked with SLE in Jamaica.

In 1985 nearly 1,700 persons who had exposure to diethylstilbestrol (DES)--520 mothers, 1,079 daughters, and 94 sons--responded to a mailed questionnaire about their general health status. Results were compared with responses to the 1985 National Health Interview Survey and other population-based studies. As with research findings in animals, conditions that suggest possibly impaired immune function--that is, respiratory tract infections, asthma, arthritis, and lupus--were reported more frequently among the persons with DES exposure. Conditions that may involve altered endocrine function were also more frequent among such persons. Given the biased sample, findings from this preliminary survey are seen as guidelines to areas meriting more rigorous research.

As incidence of SLE is high in Blacks, we studied HLA and SLE associations in the French West Indies, whose population is racially mixed. Forty-seven coloured SLE patients have been typed in HLA A,B,C and DR. We observed B8 association in nearly all of the studies. B15 association, more frequent in Caucasians, was found, also B53 association, a Black variant of B5 more frequent in Blacks. We did not find any class II association.

One hundred and one patients with systemic lupus erythematosus (SLE) from North Indian stock are presented. The clinical manifestations, laboratory parameters, causes of death, and survival are compared and contrasted with the other major reported series. SLE of North Indian Asians has several features comparable to those reported from the West, but other features are more similar to the SLE seen in Mongoloid races.

Spontaneous bacterial peritonitis (SBP), a fascinating disease that had been reported perhaps 50 times in varying guises over the preceding century, suddenly burst forth in the 1960s and was recognized in clusters of cases almost simultaneously in Paris, London, and West Haven, Connecticut. The spectrum of the disease has broadened. Initially, it was associated almost exclusively with alcoholic cirrhosis, but it has now been found in association with posthepatitic cirrhosis, cryptogenic cirrhosis, chronic active liver disease, and, occasionally, in biliary cirrhosis and cardiac cirrhosis. Recently, it has been reported in alcoholic hepatitis and acute viral hepatitis. It occurs occasionally in malignant ascites and in pancreatitis in the absence of cirrhosis. It is surprisingly common in disseminated lupus, in which it occurs relatively more commonly than in alcoholic cirrhosis. A similar syndrome, primary peritonitis, occurs frequently in children with nephrotic ascites. The clinical pattern of SBP has broadened. Initially it consisted of abdominal pain, fever, rebound tenderness, hypoactive bowel sounds, hypotension, encephalopathy, and cloudy ascites with large numbers of polymorphonuclear leukocytes in ascitic fluid. Each and every symptom, sign, and laboratory abnormality may be absent; indeed, the syndrome can be completely silent. Initially, the causative bacteria appeared to be almost exclusively enteric, but now the list of bacteria isolated in cases of SBP looks like a bacteriology textbook. Anaerobes are rare. Multiple organisms usually suggest nonspontaneous origin such as perforation or vasopressin induction. The differentiation between spontaneous and nonspontaneous bacterial peritonitis is crucial in the differential diagnosis. The great majority of cases of SBP develop in the hospital, 80% more than one week after admission. It is therefore a nosocomial disease that may be precipitated by procedure-induced bacteremia, gastrointestinal bleeding, or diarrhea, and it tends to occur in patients with low ascitic fluid protein (complement) concentrations and severe portal-systemic shunting.
