The influence of age on the prevalence of individual clinical manifestations of systemic lupus erythematosus (SLE) has not been adequately distinguished from racial or gender influences. Therefore, we examined variations in the clinical manifestations of SLE with age in a group of 361 patients. Multivariate regression techniques, including logistic regression and analysis of covariance, were used to identify clinical features associated with age, while controlling for important confounding factors, including race, gender, duration of followup, and treatment effects. Lymphopenia was found more frequently with increasing age, while malar rash, seizures, false-positive VDRL, thrombocytopenia (in whites), proteinuria (0.5-3.5 g/day), elevated antidouble stranded DNA antibodies, and hypocomplementemia were found less frequently. No age relationship was found for the prevalence of 16 of 24 clinical features examined, including the important disease manifestations of arthritis, serositis, psychosis, nephrotic-range proteinuria, renal failure, autoimmune hemolytic anemia, and leukopenia. The use of regression analysis allows the recognition of similarities and differences in cumulative clinical features of SLE due to age in isolation from the effects of other demographic factors.

The distribution of DR3 and of extended haplotypes bearing DR3 was studied in three groups of subjects: 35 patients with rheumatoid arthritis (RA) with gold induced thrombocytopenia or proteinuria, 185 patients with RA without these side effects, and 300 normal healthy controls. The extended haplotypes bearing DR3 were analysed with cDNA probes for DR alpha, DR beta, DQ alpha, and DQ beta genes. The data showed that the prevalence of DR3 was significantly higher in patients who developed gold induced thrombocytopenia or proteinuria than in normal controls or patients with RA without these side effects. Distribution of three extended haplotypes bearing DR3 (B8, DR3; B18,DR3; non-B8,non-B18,DR3) in patients with RA with thrombocytopenia or proteinuria was significantly different from that in normal controls, but not from that in patients with RA without these toxic reactions. Southern blot analysis of DR, DQ genes with cDNA probes showed that the extended haplotype bearing B8,DR3, which carries DQA2.1 and DQB2.1 genes, was present in a significantly higher proportion of patients with RA with gold induced thrombocytopenia or proteinuria (22/24, 92%) than in patients with RA without these side effects (32/45, 71%) or normal subjects (40/61, 66%). The data suggest that the genomic region on chromosome 6 involved in susceptibility to gold induced thrombocytopenia or proteinuria should be extended to the DQA2, DQB2 gene loci.

A 12-year-old girl with transverse myelopathy, massive pleural effusion and ascites as the presenting features of systemic lupus erythematosus (SLE), is described. All these features developed within a week, but other manifestations of SLE such as malar rash and arthritis were not seen during the illness. Investigations revealed positive direct Coombs' test, high titer of antinuclear antibodies, elevation of serum anti-DNA antibodies, depressed complement activity, thrombocytopenia and proteinuria, indicating that she had SLE. A week after starting treatment with prednisolone 35 mg/day, the thrombocytopenia improved, and following an increase in dosage to 60 mg/day the pleural effusion and ascites diminished after two weeks, and the serological abnormalities improved after two months. The neurological disturbances were unchanged in spite of injections of methylprednisolone 1 g/day for three days from the 89th day of her illness. Review of other cases reported to be improved neurologically, suggested that the earlier initiation of corticosteroids in higher dosage might be beneficial in transverse myelopathy in SLE.

In a serological survey among Dutch patients suspected of leptospirosis, using a recently developed enzyme-linked immunosorbent assay, a patient was traced with a high antibody titre to Hantaan virus. No anti-leptospira antibodies were detected in this 27-year-old man. Shortly before he had been admitted to the hospital with progressive dyspnoea and coughing, accompanied with high fever. An interstitial pneumonia was diagnosed. He subsequently developed a progressive renal failure with proteinuria and polyuria. Later a liver failure accompanied with thrombocytopenia, anaemia and coagulation disturbances occurred. Before an aetiological diagnosis was made, the patient was treated with erythromycin. The patient eventually recovered completely. Based on the clinical symptoms and the positive serology, it was concluded that the disease diagnosed had probably been caused by a Hantaan virus infection. The diagnostic value of Hantaan virus serology in patients with similar symptoms is stressed.

Clinical symptoms and laboratory measures of renal and liver function, coagulation, and inflammatory parameters were prospectively studied in 74 hospitalized patients (14-74 years of age) with serologic evidence of nephropathia epidemica. The most common clinical findings were acute onset of symptoms, fever (greater than or equal to 38 degrees C), thirst, headache, nausea, back pain, vomiting, myalgia, and abdominal pain. Twenty-seven patients (37%) had hemorrhagic manifestations, i.e., epistaxis, melena, hematemesis, petechial bleeding, macroscopic hematuria, or metrorrhagia. Disseminated intravascular coagulation developed in four patients. Fifty-one percent had thrombocytopenia. Proteinuria was recorded for all patients, while hematuria and glucosuria were noted for 85% and 58%, respectively. Serum creatinine levels were elevated in 71 (96%) of the patients. Levels of C-reactive protein or erythrocyte sedimentation rates were elevated in all cases, usually to levels found in serious bacterial diseases. Sixty-six (89%) of the patients were followed for up to 7 months, at which time all had recovered clinically. No patient died or required dialysis. We conclude that nephropathia epidemica in Sweden has a clinical picture similar to that of hemorrhagic fevers in other parts of the world, but with a milder course and a better prognosis.

In this study, we demonstrated that the patients with PSS who develop proteinuria during the course are much more prone to develop lung fibrosis, telangiectasia, serositis and esophageal hypomotility. They also exhibited positive LE cell phenomenon, lupus band test, thrombocytopenia and leukopenia. The mortality rate is significantly higher in proteinuria positive patients and abnormal clinical data described above seem to be the risk factors for the development of renal involvement in PSS.

To evaluate risk for exacerbation of systemic lupus erythematosus (SLE) during pregnancy, we prospectively evaluated 80 pregnant women with SLE for manifestations of disease activity. Fifty-three of these women were not taking prednisone at the time of conception. Disease activity was scored in 4 ways: global assessment, prednisone therapy, cumulative number of organ systems with abnormalities, and display of abnormalities of each organ system. No patient received prophylactic therapy to prevent disease exacerbation. Thrombocytopenia, proteinuria, and hypocomplementemia were the most common abnormalities and were usually attributable to the pregnancy complications of preeclampsia and anticardiolipin antibody syndrome rather than to SLE. If all possible abnormalities were attributed to SLE, disease exacerbation occurred in less than 25% of all patients; if only SLE-specific abnormalities were counted, disease exacerbation occurred in less than 13%. Worsening of SLE is uncommon in pregnancy, and prophylactic prednisone therapy is unnecessary.

Renal vein thrombosis in early infancy is a complication of dehydration and prolonged hypotension. The onset is usually acute and the most common clinical signs are uni- or bilateral frank masses, hematuria, proteinuria and thrombocytopenia. In most cases, with conservative management, the late outcome is favorable. In the adult, renal vein thrombosis is often a silent complication of the nephrotic syndrome, the hypercoagulability of which may be an important factor in the pathogenesis of the thrombosis. Clinically, the presentation of a sudden complete occlusion is that of severe abdominal and lumbar pain with hematuria and loss of function of the kidney that suffers hemorrhagic infarction. Physical examination often reveals an enlarged kidney. With gradual occlusion, renal function is preserved. The initial diagnostic approach is with ultrasound studies and computed tomography; definitive diagnosis is established by renal venography or by selective renal arteriography. In general, a conservative approach including the use of anticoagulant treatment is preferred to surgical intervention. Priapism is a persistent painful penile erection due to ischemic or non-ischemic causes; therapeutic intracavernosal injection of papaverine is becoming the most common cause. In early and mild stages, aspiration of blood from the corpora cavernosa supplemented with intracavernosal irrigation with alpha-stimulating agents is the procedure of first choice; in late and severe ischemia, a shunt procedure may become necessary. Hepatic vein thrombosis occurs in association with a number of conditions considered predisposing factors including the use of oral contraceptives. The clinical picture may be that of an acute illness with abdominal pain, hepatomegaly, ascites and hepatic failure as well as early death. More often, the onset is insidious with slowly developing ascites and wasting. For the diagnosis, hepatic scintigraphy may be helpful but, at present, ultrasonography, computed tomography and magnetic resonance scanning are procedures of choice. There is, as yet, no adequate treatment. A fatal outcome may be prevented by surgical decompression of the congested liver and, in recent years, liver transplantation has been employed. Portal vein thrombosis, in children, is usually considered a complication of umbilical sepsis or a result of a congenital abnormality of the portal vein. In adults, the most frequent causes are hepatic cirrhosis and neoplasia. Clinically, there may be a sudden appearance of ascites with resolution in a symptom-free interval until the onset of other features of portal hypertension occur. Currently, ultrasound real-time imaging supplemented with Doppler capability, computed tomography and magnetic resonance scanning provide the necessary diagnostic information. Variceal hemorrhage is often the first major complication requiring treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

The effects of injected native and cationized bovine serum albumin (BSA- and BSA+ respectively) were evaluated in rats which subsequently received anti-BSA. Thrombocytopenia, low creatinine clearance (Ccr), increased proteinuria, capillary swelling, mild tuft necrosis and BSA+ deposits in glomeruli resulted within 24 h of BSA+ injection. Later BSA+ produced mesangial expansion glomerular capillary wall (GCW) thickening and deposits of BSA+ accompanied by rabbit anti-BSA and rat anti-BSA which correlated well with small mesangial, subendothelial and subepithelial electron-dense granular accumuli. These latter enlarged considerably after the injection of anti-BSA. BSA- controls showed minimal or no lesions. The disappearance from the blood (t1/2) of a single dose of immune complexes (IC) prepared with chromatography-purified, radioiodinated anti-BSA - BSA- and BSA+ was determined in another group of rats. The t1/2 of BSA- anti-BSA was 42.8 h (95% confidence: 39.8-46.2) while that of BSA+ anti-BSA was 52.5 h (48.1-57.8). These results suggested that serum sickness glomerulitis developed only in rats injected with BSA+, due to in situ IC which presumably grew by accretion of foreign anti-BSA. Circulating IC may have developed and colocated with the latter, with dissociation and recombination at these sites. It is postulated that the functional-immunomorphological changes and the slow removal of cationized IC reported herein could be explained by the highly positive net charge of the injected antigen.

The purpose of this study was to establish the prevalence and clinical significance of thrombocytopenia in pregnancy-induced hypertension (PIH). Thrombocytopenia, defined as a platelet count less than 100,000/mm3 was found in 11.6% of all patients with PIH. Logistic regression analysis was used to assess the relative contribution of thrombocytopenia, proteinuria, and the degree of hypertension to maternal and perinatal outcome. Thrombocytopenia was the principal contributor to the occurrence of abdominal pain, liver dysfunction, the presence of schistocytes in the peripheral smear, proteinuria, fetal distress, and the requirement for blood transfusions. Thrombocytopenia was also associated with a higher incidence of preterm delivery and intrauterine growth retardation. The nadir platelet count occurred within 48 hours of delivery in 56.7% (21 of 37) of cases. The median number of days for recovery of the thrombocytopenia was 2.0 days (range, 0 to 8 days). In five patients thrombocytopenia preceded the clinical manifestations of PIH. We conclude that thrombocytopenia is an independent and important risk factor for the occurrence of maternal and perinatal complications in PIH.
