Abstract
OBJECTIVE To identify the most common causes of diffuse alveolar hemorrhage (DAH) and the evolution of cases during hospitalization. PATIENTS AND METHODS A review of cases diagnosed with DAH; the diagnoses were classified according to existing criteria and the progression of the cases was determined. RESULTS We identified 17 cases of DAH, with the leading cause being ANCA associated vasculitis (41% of cases), followed by cases secondary to drugs (18%). In 35% of the cases, there was a failure in identifying an etiology. Six patients died (35%), the only factor associated with mortality was male gender 5/6 vs 3/11, p=0.05. CONCLUSIONS The most frequent cause of alveolar hemorrhage was ANCA associated vasculitis. The mortality in DAH is about 35%, males seem to have a worse prognosis.

Abstract
This study was conducted to investigate the frequency and significance of some antinuclear autoantibodies in Omani patients with systemic lupus erythematosus (SLE). Anti-nuclear antibodies (ANA), anti-double stranded-DNA (anti-dsDNA), and anti-Smith (anti-Sm) autoantibodies were investigated in 60 Omani patients clinically diagnosed with SLE according to the American College of Rheumatology Criteria. The SLE group included 57 females and 3 males with an average age of 26 years. In addition, a group of 60 healthy Omanis (26 females and 34 males; average age 25 years) was used as a control. ANA patterns and autoantibody profile were assayed by indirect immunofluorescence assay using Hep-2 cells and liver/kidney/stomach tissue, respectively. Anti-dsDNA were examined by enzyme-linked immunosorbent assays; anti-Sm antibodies were measured by immunoblotting technique. Out of the 60 SLE patients, 59/60 (98.3%) were seropositive for ANA. Anti-dsDNA and anti-Sm each was detected in 50/60 (83.3%) of the Omani patients. The homogenous pattern of ANA was detected in 30/60 (50%) of patients, whereas the frequency of fine-speckled and coarse-speckled was 16/60 (26.7%) and 6/60 (10%), respectively. High titers (≥ 1:320) of ANA was detected in 56/60 (93.3%) of SLE patients. High titers of anti-Sm were detected in 22/60 (33.3%) of patients. High titers (>100 IU/ml) of anti-dsDNA were detected in 40/60 (66.7%) of patients. In the control group, ANA were detected in 8/60 (13.3%) but at low titers, whereas anti-dsDNA and anti-Sm were not detected in the healthy control group. This study shows that anti-Sm is as important as the anti-dsDNA for confirming the diagnosis of SLE and that anti-Sm occurs at a much higher frequency (83.3%) than that reported in other populations indicating the importance of this specific autoantibody for the diagnosis and possibly prognosis of Omani SLE patients.

Abstract
Systemic lupus erythematosus (SLE) is characterized by multiple autoantibodies and complement activation. Recent studies have suggested that anti-nuclear antibody (ANA) positivity may disappear over time in some SLE patients. Anti-double-stranded DNA (dsDNA) antibody titers and complement levels may vary with time and immunosuppressive treatment, while the behavior of anti-extractable nuclear antigen (ENA) over time is less well understood. This study sought to determine the correlation between historical autoantibody tests and current testing in patients with SLE. Three hundred and two SLE patients from the ACR Reclassification of SLE (AROSE) database with both historical and current laboratory data were selected for analysis. The historical laboratory data were compared with the current autoantibody tests done at the reference laboratory and tested for agreement using percent agreement and Kappa statistic. Serologic tests included ANA, anti-dsDNA, anti-Smith, anti-ribonucleoprotein (RNP), anti-Ro, anti-La, rheumatoid factor (RF), C3 and C4. Among those historically negative for immunologic markers, a current assessment of the markers by the reference laboratory generally yielded a low percentage of additional positives (3-13%). However, 6/11 (55%) of those historically negative for ANA were positive by the reference laboratory, and the reference laboratory test also identified 20% more patients with anti-RNP and 18% more with RF. Among those historically positive for immunologic markers, the reference laboratory results were generally positive on the same laboratory test (range 57% to 97%). However, among those with a history of low C3 or C4, the current reference laboratory results indicated low C3 or C4 a low percentage of the time (18% and 39%, respectively). ANA positivity remained positive over time, in contrast to previous studies. Anti-Ro, La, RNP, Smith and anti-dsDNA antibodies had substantial agreement over time, while complement had less agreement. This variation could partially be explained by variability of the historical assays, which were done by local laboratories over varying periods of time. Variation in the results for complement, however, is more likely to be explained by response to treatment. These findings deserve consideration in the context of diagnosis and enrolment in clinical trials.

Abstract
OBJECTIVE To determine some of the neuropsychiatric manifestations of systemic lupus erythematosus (SLE) by applying multimodal neurophysiological and psychometric studies. PATIENTS AND METHODS Twenty-six SLE patients were evaluated for neurological and psychiatric disorders and compared with 26 healthy controls matched for age, sex, education, and social class. The severity of SLE disease was assessed. Each subject was subjected to the following examinations: laboratory, neurophysiology, magnetic resonance imaging of the brain, transcranial duplex, Modified Mini-mental State Examination, Cognitive Assessment Scale Inventory, Hamilton Depression Scale, and Hamilton Anxiety Scale. RESULTS The mean age of subjects was 25.9 ± 8.9 years. The most prevalent neurological manifestations were (in order of frequency) anxiety in 17 cases (65.4%), depression in 15 cases (57.7%), headache in 10 cases (38.5%), peripheral neuropathy in 7 cases (26.9%), seizures in 6 cases (23.1%), psychosis in 5 cases (19.2%), dementia in 4 cases (15.4%), radiculopathy in 4 cases (15.4%), myositis in 3 cases (11.5%), and stroke in 2 cases (7.7%). There was a significant affection in amplitude of the ulnar nerve, cognitive function impairment, and electroencephalography changes. There was a significant increased mean velocity and decreased Pulsatility Index of the most studied intracranial vessels in the patients. CONCLUSION The use of multimodal neurophysiological, transcranial duplex, and psychometric scales increases the sensitivity for detecting nervous system involvement.

Abstract
Systemic lupus erythematosus (SLE) and mixed connective tissue disease (MCTD) are autoimmune illnesses characterized by the presence of high titers of autoantibodies directed against a wide range of 'self ' antigens. Proteins of the U1 small nuclear ribonucleoprotein particle (U1 snRNP) are among the most immunogenic molecules in patients with SLE and MCTD. The recent release of a crystallized U1 snRNP provides a unique opportunity to evaluate the effects of tertiary and quaternary structures on autoantigenicity within the U1 snRNP. In the present study, an epitope map was created using the U1 snRNP crystal structure. A total of 15 peptides were tested in a cohort of 68 patients with SLE, 29 with MCTD and 26 healthy individuals and mapped onto the U1 snRNP structure. Antigenic sites were detected in a variety of structures and appear to include RNA binding domains, but mostly exclude regions necessary for protein-protein interactions. These data suggest that while some autoantibodies may target U1 snRNP proteins as monomers or apoptosis-induced, protease-digested fragments, others may recognize epitopes on assembled protein subcomplexes of the U1 snRNP. Although nearly all of the peptides are strong predictors of autoimmune illness, none were successful at distinguishing between SLE and MCTD. The antigenicity of some peptides significantly correlated with several clinical symptoms. This investigation implicitly highlights the complexities of autoimmune epitopes, and autoimmune illnesses in general, and demonstrates the variability of antigens in patient populations, all of which contribute to difficult clinical diagnoses.

Abstract
The skin is the second most frequently affected organ system in lupus erythematosus. Although only very rarely life threatening--an example is lupus erythematosus-associated toxic epidermal necrolysis--skin disease contributes disproportionally to disease burden in terms of personal and psychosocial wellbeing, vocational disability, and hence in medical and social costs. Since several manifestations are closely associated with the presence and activity of systemic lupus erythematosus, prompt and accurate diagnosis of cutaneous lupus erythematosus is essential. This review aims to cover common, rare, and atypical manifestations of lupus erythematosus-associated skin disease with a detailed discussion of histopathological correlates. Cutaneous lupus erythematosus covers a wide morphological spectrum well beyond acute, subacute and chronic cutaneous lupus erythematosus, which are commonly classified as lupus-specific skin disease. Other uncommon or less well-known manifestations include lupus erythematosus tumidus, lupus profundus, chilblain lupus, mucosal lupus erythematosus, and bullous lupus erythematosus. Vascular manifestations include leukocytoclastic and urticarial vasculitis, livedoid vasculopathy and livedo reticularis/ racemosa. Finally, we discuss rare presentations such as lupus erythematosus-related erythema exsudativum multiforme (Rowell syndrome), Kikuchi-Fujimoto disease, extravascular necrotizing palisaded granulomatous dermatitis (Winkelmann granuloma), and neutrophilic urticarial dermatosis.

Abstract
OBJECTIVE To estimate the prevalence of neuropsychiatric disorders, cerebral atherosclerosis in patients with systemic lupus erythematosus (SLE) and explore the relation between transcranial duplex findings of different intracranial vessels with neuropsychiatric affect, and Systemic lupus erythematosus disease activity index (SLEDAI). METHODS Twenty-six consecutive SLE patients were evaluated for neurological and psychiatric disorders. Another 26 subjects matched with respect to age, sex, education, and socioeconomic status formed the control group. SLE disease activity was assessed by the SLEDAI. For each participant, a complete medical history was obtained and clinical, laboratory, and neurophysiological examinations, magnetic resonance imaging of the brain, transcranial duplex for intracranial vessels, and psychometric evaluations were performed. For the psychometric evaluation, we used the Modified Mini-mental State Examination and Cognitive Assessment Scale Inventory to assess cognitive function, and Hamilton Depression Rating Scale and Hamilton Anxiety Scale to assess symptoms of depression and anxiety. RESULTS Anxiety in 65.4% is the most prevalent manifestation followed by depression in 57.7%, headache in 38.5%, peripheral neuropathy in 26.9%, seizures in 23.1%, psychosis in 19.2%, radiculopathy and dementia in 15.4% for each, myositis in 11.5%, and stroke in 7.7%. There was a significant increased mean velocity and decreased pulsatility index of most studied intracranial vessels in both patient groups than in the control group. There was significant negative correlation between SLEDAI and transcranial Doppler findings in the pulsatility index of medial circumflex artery and procoagulant activity. CONCLUSION Neurological disorders, cognitive impairment, depression, anxiety, psychosis and cerebrovascular changes detected by transcranial Doppler ultrasound are common in SLE.

Abstract
The current 2002 classification criteria do not cover the broad clinical and immunological heterogeneity of primary Sjögren syndrome (SS), since five of the six criteria focus exclusively on glandular involvement and the remaining criterion is the mandatory presence of anti-Ro/La antibodies. The aim of this study was to analyze the clinical features of patients with a well-established diagnosis of primary SS who do not fulfill the 2002 classification criteria. Five hundred seven patients diagnosed with primary SS (1993 criteria) were consecutively included and followed up. Two hundred twenty-one (44%) patients did not fulfill the 2002 criteria. These patients were older at diagnosis (p < 0.001) and had a lower frequency of parotid enlargement (p = 0.002), fever (p = 0.041), arthritis (p = 0.041), vasculitis (p = 0.050), peripheral neuropathy (p = 0.002), cranial nerve involvement (p = 0.015), raised erythrocyte sedimentation rate ( ESR) levels (p < 0.001), anemia (p < 0.001), leukopenia (p = 0.037), hypergammaglobulinemia (p < 0.001), positive rheumatoid factor ( RF; p = 0.002), and cryoglobulinemia (p = 0.049) in comparison with those fulfilling 2002 criteria. However, there were no significant differences in the prevalence of sicca features, diagnostic tests, overall systemic involvement, antinuclear antibodies , complement levels, development of B-cell lymphoma, or survival. Patients with anti-Ro antibodies had the highest frequencies of systemic features, hematological abnormalities, and altered immunological markers. In conclusion, patients fulfilling the 2002 criteria, who have either a specific histological diagnosis (lymphocytic infiltration) or highly specific autoantibodies (Ro/La), might well be considered to have Sjögren "disease." In contrast, etiopathogenic mechanisms other than lymphocytic-mediated epithelial damage could be involved in patients with negative Ro and negative biopsy, in whom the term Sjögren "syndrome" seems more adequate.

Abstract
Diagnosing vulvar intraepithelial neoplasia in a young woman presenting mainly with skin manifestations of lupus and with no other risk factors is a major challenge. The case of a 27-year-old woman with systemic lupus erythematosus and vulvar intraepithelial neoplasia is described. Although progression of vulvar intraepithelial neoplasia to invasive planocellular carcinoma is rare, prompt and adequate diagnosis and treatment will help ensure the best possible quality of life.

Abstract
The purpose of this study was to characterize the clinical and serological features of a large cohort of patients with antinuclear antibody (ANA) positive undifferentiated connective tissue disease (UCTD). Consecutive patients with UCTD, followed up at the Rheumatology Clinic of the participating centers, were included. Data from these patients were obtained by clinical evaluation and chart review. All patients were diagnosed as having UCTD on basis of the following criteria: positive ANA plus at least one clinical feature of connective tissue disease, but not fulfilling classification criteria for any differentiated connective tissue disease. One hundred eighty-four patients were studied (female patients-94.5%; mean age at time of evaluation-47 years). The most prevalent manifestations were arthralgia (66%), arthritis (32%), Raynaud's phenomenon (30%), sicca symptoms (30%), and leukopenia (19%). The prevalence of ANA was 100%, anti-SSA 20%, anti-dsDNA 14%, and anti-SSB 7%. Patients with anti-dsDNA/anti-Sm, anticentromere/anti-Scl70, or anti-SSA/anti-SSB antibodies more frequently presented a set of manifestations close to systemic lupus erythematosus (SLE), systemic sclerosis, or Sjögren syndrome, respectively. We analyze a large cohort of UCTD. Seventy-two percent of these UCTD patients present lupus-, scleroderma-, or Sjögren-like features but do not fulfill classification criteria and mostly present a mild disease.

Abstract
No new therapy for systemic lupus erythematosus has been approved. In the last decade, the development of several novel compounds has been pursued for lupus, but so far nothing has been proven to be effective. This review discusses some of the reasons why it may be so difficult to demonstrate that a novel therapy is effective for this disease. These include the complexity of the disease itself; the lack of reliable outcome measures; our limited understanding of the pathogenesis of the disease; the propensity of lupus patients to have bad outcomes and to react to medicines in unusual ways; the heterogeneity of the patient population; the unpredictable course of disease in individual patients; and the lack of reliable biomarkers. Although some of the tested targeted compounds that are apparently based on strong preclinical and mechanistic data may indeed not be effective therapies for SLE, it is hard not to believe that among the various specific agents now being tested that at least some of them should downregulate the abnormal immunoregulation characteristic of SLE, and thus be clinically effective. We need to be persistent and imaginative in identifying these effective agents and proving their efficacy so that they may be widely used in our lupus populations.

The role of tumour necrosis factor (TNF-α) signalling adapters in lupus nephritis (LN) is poorly understood. This study investigated renal expression of TNF-α and TNF signalling adapter proteins, including TNF receptor-associated death domain protein (TRADD), receptor-interacting protein (RIP) and TNF receptor-associated factor-2 (TRAF-2) in patients with LN. The renal expression of proliferating cell nuclear antigen (PCNA) and CD68 was also measured. The study showed that glomerular and tubular expression of TNF-α, TRADD, RIP and TRAF-2 was significantly up-regulated in class III and IV LN in which the intense staining was observed on the crescents, proximal and distal tubules and interstitial mononuclear cells. The number of PCNA-positive cells and CD68-positive cells (macrophages) was increased obviously in class III and IV LN. There was a correlation between the expression levels of TNF-α, TRADD, RIP, TRAF-2 and the number of PCNA-positive or CD68-positive cells and active index of renal pathology. These findings suggest that TNF-α and TNF-α adapters in patients with LN play a role in immunopathogenic injury via transmitting abnormal cell proliferating and proinflammatory signals. The findings have provided further insights into the role of TNF-α and its adapter proteins in the pathogenesis of LN and have important therapeutic implications.

Abstract
To validate the use of multiplex case families in studying the pathogenesis of systemic lupus erythematosus (SLE), we investigated the pattern of familial SLE in relation to sporadic SLE in the highly consanguineous Kuwaiti population. We sought to determine whether familial and sporadic SLEs have the same clinical and serological features. We compared 21 cases of familial SLE in 21 families with 42 non-familial SLE controls matched for age, sex and duration of disease. Twenty-one families, in which the diagnosis of SLE was verified in at least two relatives, were included in the study. The diagnosis was made according to the revised 1982 American College of Rheumatology criteria. There were no significant differences in clinical features or serological manifestations between familial SLE cases and their matched controls. However, our results showed that the frequency of La/SSB antibodies was higher in the sporadic group (P = 0.048), although this was not significant after application of Bonferroni's correction for the number of comparisons. Familial cases of SLE were more likely to present at younger age of 20 years and sporadic cases at 26 years (P = 0.006). The prevalence of familial SLE was 27.4%. We have found that familial and sporadic cases of SLE are broadly similar, and it is justified to include multiple case families in genetic studies.

Abstract
Approximately 15% of patients with systemic lupus erythematosus (SLE) will have the onset of their disease in childhood or adolescence. Due to the broad range of possible clinical features of SLE, the diagnosis may be difficult to make in a general pediatric or community setting. The common symptoms of SLE in children and adolescents include fever, fatigue, weight loss, arthritis, rash and renal disease. SLE is more common in non-Caucasian ethnic groups and should be considered in the differential diagnosis of a multisystem disease in these patients. In this article, the classification criteria for SLE are discussed, and an approach to making an accurate and timely diagnosis of this disease is considered.

Abstract
Antinucleosome antibodies (AnuA) are increasingly recognized as an important biomarker in the diagnosis and subset stratification of patients with systemic lupus erythematosus (SLE). The aim of the study was to determine the sensitivity, specificity, and clinico-serological correlates of AnuA in black South Africans with SLE. We performed a cross-sectional study of 86 SLE patients attending a tertiary center and 87 control subjects. AnuA were tested using a second-generation enzyme-linked immunosorbent assay (ELISA). The sensitivity, specificity, positive predictive value, and negative predictive value of AnuA were 45.3, 94.3, 88.6, and 63.6%, respectively. The presence of AnuA were strongly associated with the co-presence of anti-dsDNA antibodies (OR = 3.4, p < 0.0005) and antihistone antibodies (OR = 15.7, p < 0.00001). Patients who were seropositive for AnuA were more likely to have skin involvement (discoid lupus and/or malar rash) and had higher SLE disease activity index (SLEDAI) scores and Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) damage scores (p < 0.05). IgG anticardiolipin antibody (aCL) levels showed a significant correlation with AnuA ratios (p < 0.01). Our findings provide further evidence that AnuA are a sensitive and specific diagnostic biomarker in SLE. Moreover, our finding that the presence of AnuA, but not anti-dsDNA antibodies, are associated with worse SLICC/ACR damage scores suggest that AnuA may have a role in predicting disease outcome. The correlation between IgG aCL and AnuA is a novel finding that merits further studies to determine possible common peptide specificities of the antibodies.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem inflammatory disease that is often difficult to diagnose in the emergency department. It is an autoimmune disease with great variability in presentation and course. Moreover, the atypical or incomplete presentation is common in children and can result in delay in diagnosis. Consideration of the possibility of SLE is important when evaluating a patient with symptoms and/or signs suggesting multisystem disease. The emergency physician must maintain a high degree of suspicion for the early diagnosis and management of this important condition. We present 3 children who presented to emergency department with different initial manifestations of SLE.

Abstract
The 'ESHRE/ASRM consensus on diagnosis, nomenclature and long-term health risks of polycystic ovarian syndrome (PCOS)' (conference in Rotterdam, Netherlands, March, 2003), which was criticized shortly after its oral presentation in 2003, is still being debated following its publication in 2004. Therefore, an extended, intensive analysis of all parameters and their combinations has been performed, differentiating between inclusion and exclusion criteria. By doing this, the profound significance of the endocrinological part of the syndrome is highlighted. The nomenclature, semantic meaning of terms, definitions, structural balancing, specificity, practicability, flexibility, limitations and reproducibility for both individualization, as well as grouping from the clinical and scientific perspective, have been examined in detail. This analysis supports previous critical comments, and reaches the conclusion that the recommendations of the consensus lack accuracy and specificity, a weakness that results in the risk of overdiagnosis and in a lack of reproducibility. Altogether, they fail to fulfil the criteria of universal guidelines on several levels. Instead, a profound paradigm shift is demanded, from an inconsistent perception to a more systematic, balanced and comprehensive view. A short indication on an alternative sweeping concept of a strictly defined, therapy-targeted classification and diagnostic procedure of female functional androgenization is presented.
