A case of disseminated intravascular coagulation (DIC) in a patient with systemic lupus erythematosus (SLE) with acute liver dysfunction is described. A 37-year-old man with SLE developed acute DIC and marked liver damage after fracture of the right clavicle and pharyngitis. Treatment with high-dose steroids, heparin, antithrombin III, gabexate mesilate, and antibiotics resulted in prompt improvement. The recovery of an SLE patient after acute DIC and marked liver damage is considered very rare. We report here such a case and discuss the previous reports.

The clinical and diagnostic features of 29 adult patients with H. influenzae septic arthritis are reviewed. Twelve men and 17 women ranging in age from 22 to 82 years developed the infection. H. influenzae septic arthritis is an acute, febrile disease with a mean duration of symptoms before diagnosis of 4 days. Fifteen patients had monoarticular arthritis, 6 with an infected knee. Polyarticular involvement, with a range of 2 to 9 joints, was diagnosed in 14 patients. Nineteen patients had concurrent extraarticular sites of infection, including meningitis, pneumonia, pharyngitis, sinusitis, conjunctivitis, and cellulitis. Twenty-two of 29 patients had predisposing factors for infection, including ethanolism, trauma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, splenectomy, multiple myeloma, lymphoma, gout, and acquired common variable hypogammaglobulinemia. Characteristic synovial fluid findings included purulent, greenish fluid, elevated WBC count, and gram-negative pleomorphic microorganisms. Treatment for these patients included antibiotic therapy, most often ampicillin and chloramphenicol, and joint drainage by repeated arthrocentesis or arthrotomy. A favorable outcome was reported in 25 of 29 patients. Hemophilus influenzae septic arthritis should be suspected in adults who are immunocompromised and have a concurrent extraarticular source of infection.

Rheumatoid factors (RF), autoantibodies to IgG, have been postulated to have some pathogenetic role in the development of some types of glomerulonephritis. A simple and sensitive solid-phase fluorescence immunoassay was employed to determine whether IgG, IgA and IgM RF were detectable in sera from patients with various types of glomerulonephritis, rheumatoid arthritis (RA) and those with various streptococcal infections. IgG, IgA and IgM RF were significantly increased in the majority of patients with RA, lupus nephritis (SLE), acute poststreptococcal glomerulonephritis (APSGN) and various streptococcal infections. The titers of IgG and IgA RF were significantly higher in patients with APSGN than in those with simple pharyngitis. IgM RF was increated in patients with IgA nephropathy (IgA-N) and in those with membranoproliferative glomerulonephritis type I (MPGN). No significantly high RF was observed in membranous nephropathy (MN) or chronic mesangial proliferative glomerulonephritis without IgA deposition (PGN). It is suggested that some autologous immune mechanisms may be involved in the pathogenesis of some types of glomerulonephritis.

Clinical experience suggests that allergic signs and symptoms are more frequently observed in patients with systemic lupus erythematosus than in the general population. The aim of this paper was to evaluate the frequency of allergic clinical manifestations in systemic lupus erythematosus (SLE) by anamnesis. Sixty three SLE patients, 51 cases of other autoimmune diseases and 133 healthy individuals, were included in the study. The protocol was taken from Goldman's paper on the same subject (4): urticaria, rhinitis, pharyngitis, conjunctivitis, asthma, eczema and allergy to foods, drugs and insect stings were recorded. The results disclosed that 76% of SLE cases, 37% of those with other autoimmune diseases and versus healthy controls had had one or more of those clinical manifestations throughout their lives (SLE versus other autoimmune diseases and versus healthy controls; p: less than 0,0005; other autoimmune diseases versus healthy controls; p: not significant). The frequency of each of the following-urticaria, pharyngitis, conjunctivitis and food allergy was statistically increased in SLE. Furthermore, patients with SLE had the highest incidence of different types of clinical manifestations per individual. Allergic manifestations in SLE are thought to express: a higher level of hypersensitivity to exogenous antigens, or disease activity through cytotropic autoantibodies or through anaphylactoid products of complement activation.

To analyze the outcome of systemic lupus erythematosus (SLE) associated with acute disseminated intravascular coagulation (DIC) and also to clarify the clinical factor(s) contributing to the outcome, we retrospectively investigated 120 SLE patients treated between 1981 and 1991. Eight of these patients (6.7%) developed acute DIC; four recovered and the other four died within 2 weeks of onset. Infection preceded acute DIC in all these patients. Acute DIC associated with atypical pneumonia was always fatal, while the patients with pharyngitis or urinary tract infection survived when they were treated adequately. Comparison of the dead and surviving groups revealed that the activity of SLE before the onset of DIC, the severity of DIC, and the treatment given for DIC and the coexistent infection were not significantly related to a fatal outcome. However, severe infection such as atypical pneumonia in patients with secondary immunodeficiency was likely to be fatal irrespective of the presence of DIC.

As a marker of in vivo B-cell activity, urine levels of free light chain (FLC) were measured twice weekly by radioimmunoassay (RIA) and correlated with disease activity over periods of 5-10 months in seven patients with systemic lupus erythematosus (SLE). In addition, RIA-measured urine albumin was used to track glomerular injury, and alpha1-microglobulin (alpha1-M) levels, 28- to 32-kDa protein, provided control measurements on excretion of low-molecular-weight proteins. As controls, urine FLC levels were obtained from healthy normals and in subjects with acute pharyngitis, sickle-cell anemia, and acute sepsis or pneumonia. The control results showed that with acute sepsis/pneumonia had marked increases in urine FLC, while pharyngitis and sickle-cell controls had normal FLC levels. In SLE, active patients receiving intravenous cyclophosphamide and high-dose steroids exhibited highly increased urine FLC that fluctuated widely during therapy and fell to normal range levels with disease remission. During active SLE, urine albumin often was increased, while alpha1-M levels remained in normal range. In contrast to the increased FLC of active disease, inactive patients on low-dose maintenance therapy had predominantly normal FLC levels throughout the collection period. These results support our hypothesis that longitudinal levels of urine FLC can be used to track disease-related B-cell activity in SLE. Furthermore, we suggest that the urine FLC of active SLE would share LC idiotype with the clonal associated in vivo secreted Ig, and thus permit the identification of these antibodies that are targeted to the culprit immunogen(s) responsible for the pathogenesis of SLE.

Rheumatic heart disease (RHD) or acute rheumatic fever (ARF) develops as a consequence of an exaggerated immune response to Group A beta haemolytic streptococci causing pharyngitis. The molecular mimicry appears between human cardiac myosin and M protein of group A streptococcal membranes. The polymorphism of the protein tyrosine phosphatase nonreceptor 22 (PTPN22) gene, which encodes an important negative regulator of T cell activation, has been reported to be associated with susceptibility to several autoimmune diseases such as SLE and RA. The objective of this study was to investigate whether PTPN22 R620W polymorphism confers susceptibility to RHD in Turkish population. PTPN 22 R620W (rs2476601, A/G) polymorphism was genotyped by PCR-RFLP in 121 patients with RHD who fulfilling the revised classification criteria of Jones, and 160 healthy control (HC), and also 137 SLE as a diseased-control. The frequency of GG and AG genotypes were found to be 94% (114), 6% (7) in RHD, respectively and 96% (153) and 4% (7) in HC, respectively. The homozygous AA genotype was not present in RHD and HC. There was no statistically significant difference between RHD and HC according to the frequency of AG heterozygote genotype (P = 0.831; OR = 1.13; 95% CI 0.37-3.46). The frequency of the rare allele A was also very similar in RHD patients and HC (3, 2% respectively). A similar result was also found between SLE and HC. Our results demonstrated that the PTPN22 R620W polymorphism is not associated with RHD nor with SLE in Turkish population.

Infections are considered one of the most common causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE), and occasionally can trigger a catastrophic antiphospholipid syndrome (APS). We describe a 22-year-old SLE patient with lupus nephritis under immunosuppressant therapy and asymptomatic carrier of antiphospholipid antibodies, who was admitted with tonsillitis and acute hepatitis, developing multiorgan failure in a few hours. Postmortem examination revealed hepatic necrosis, tonsillitis, pharyngitis and uterine cervicitis caused by herpes simplex virus (HSV) together with microthrombosis in lungs and glomerular arterioles, suggesting the diagnosis of fulminant HSV disseminated infection and catastrophic APS.
