The severity of systemic lupus erythematosus (SLE) patients with pulmonary bacterial infection varies widely. We investigated the significance of procalcitonin (PCT) and C-reactive protein (CRP) in evaluating the severity of pulmonary infection in SLE patients. This retrospective study contained a total of 117 patients (107 women and 10 men) with SLE from January 2010 to June 2011. Serum levels of PCT and CRP were measured by enzyme-linked immunosorbent assay. The severity of pulmonary bacterial infection (PBI) was evaluated using the pneumonia severity index (PSI)...

Cervical cancer, the second most common cancer affecting women in Northern Brazil, is strongly associated with human papillomavirus (HPV) infection. Diseases affecting the immune state of a patient, including autoimmune diseases like systemic lupus erythematosus (SLE), can lead to persistent HPV infection and cancer. We evaluated cervical HPV prevalence and the associated risk factors in 70 women with SLE in the city of Belém, located in Brazilian Amazon. HPV DNA was detected by PCR using primers MY9 and MY11...

Anti-lipid IgG antibodies are produced in some mycobacterial infections and in certain autoimmune diseases [such as anti-phospholipid syndrome, systemic lupus erythematosus (SLE)]. However, few studies have addressed the B cell responses underlying the production of these immunoglobulins. Anti-lipid IgG antibodies are consistently found in a murine model resembling human lupus induced by chlorpromazine-stabilized non-bilayer phospholipid arrangements (NPA). NPA are transitory lipid associations found in the membranes of most cells; when NPA are stabilized they can become immunogenic and induce specific IgG antibodies, which appear to be involved in the development of the mouse model of lupus...

SLE is a chronic autoimmune disease involving multiple systems. Patients with SLE are highly susceptible to infections due to the combined effects of their immunosuppressive therapy and the abnormalities of the immune system that the disease itself causes, which can increase mortality in these patients. The differentiation of SLE activity and infection in a febrile patient with SLE is extremely difficult. Activity indexes are useful to identify patients with lupus flares but some clinical and biological abnormalities may, however, make it difficult to differentiate flares from infection...

IgG autoantibodies mediate pathology in systemic lupus patients and lupus-prone mice. In this study, we showed that the class-switched IgG autoantibody response in MRL/Fas(lpr/lpr) and C57/Sle1Sle2Sle2 mice was blocked by the CID 1067700 compound, which specifically targeted Ras-related in brain 7 (Rab7), an endosome-localized small GTPase that was upregulated in activated human and mouse lupus B cells, leading to prevention of disease development and extension of lifespan. These were associated with decreased IgG-expressing B cells and plasma cells, but unchanged numbers and functions of myeloid cells and T cells...

Over the last 10 years, the number of identified polyomaviruses has grown to more than 35 subtypes, including 13 in humans. The polyomaviruses have similar genetic makeup, including genes that encode viral capsid proteins VP1, 2, and 3 and large and small T region proteins. The T proteins play a role in viral replication and have been implicated in viral chromosomal integration and possible dysregulation of growth factor genes. In humans, the Merkel cell polyomavirus has been shown to be highly associated with integration and the development of Merkel cell cancers...

Connective tissue diseases (CTDs) are a heterogeneous group of conditions characterized by circulating autoantibodies and autoimmune-mediated organ damage. Common CTDs with lung manifestations are rheumatoid arthritis, scleroderma or systemic sclerosis, Sjögren syndrome, polymyositis/dermatomyositis, systemic lupus erythematosis, mixed connective tissue disease, and undifferentiated connective tissue disease. The most common histopathologic patterns of CTD-related interstitial lung disease are nonspecific interstitial pneumonia, usual interstitial pneumonia, organizing pneumonia, and lymphoid interstitial pneumonia...

BACKGROUND: The current standard for induction phase treatment of lupus nephritis is steroid combined with mycophenolate mofetil or pulse intravenous cyclophosphamide (IVC). The lowest dose of IVC recommended for induction therapy is that used in the Euro-Lupus Trial. It is not known whether same cumulative dose of IVC would be effective when given over six months. METHODS: We carried out a prospective, observational study on 41 patients of biopsy-proven lupus nephritis (class III, IV, V or mixed)...

We encountered a case of a middle-aged woman with systemic lupus erythematosus. As the patient had progressive peripheral neuropathy including foot drop, we intended to treat her with intensive immunosuppressive therapy as soon as possible. Pretreatment assessment, however, revealed multiple nodular lesions in the lungs and bones, suggesting disseminated tumor metastasis or miliary tuberculosis. To our surprise, gallium and bone scintigraphy as well as cytodiagnosis revealed no sign of malignancy or infection, leading us to suspect the presence of another multisystem disorder...

Patients with systemic lupus erythematosus (SLE) often require immunosuppression to induce remission of active disease exacerbations. Over the past two decades, treatment modalities for this condition have emerged leading to improved morbidity from disease related outcomes. However, as a result, infection risks and patterns have changed, leading to higher rates of opportunistic infections among this population. We report four cases of cytomegalovirus (CMV) in patients with SLE who received immunosuppressive therapy, including pulse steroids, antimetabolites such as mycophenolate mofetil, and alkylating agents such as cyclophosphamide...

A patient with severe lupus nephritis developed thrombocytopenia during treatment with high-dose steroids. In addition to viral- or disease-induced cytopenia, the pathology was believed to arise from diverse contributing factors, such as thrombotic microangiopathy and heparin-related thrombocytopenia (HIT). By combining plasma exchange therapy and intravenous cyclophosphamide, we successfully controlled the SLE activity and improved the thrombocytopenia. An antecedent bacterial infection or SLE activity is believed to have contributed to the concurrent HIT...

The aim of this study was to review and evaluate systematically the scientific evidence on the relationship between systemic lupus erythematosus (SLE) and cutaneous warts (CW) caused by human papillomavirus (HPV) infection. With strict inclusion and exclusion criteria, we extensively searched the PUBMED, BVS (Virtual Health Library), and SCOPUS databases for the studies that evaluated the prevalence of CW in patients with SLE. Secondary references were additionally obtained from the selected articles. Only four articles met the research criteria and showed a higher frequency of CW in SLE patients compared to healthy controls...

An association between immune-mediated diseases and cervical pre-malignant and malignant lesions is described, having the human papillomavirus (HPV) infection a causal role. Related studies have been generally focused on systemic lupus erythematosus (SLE) patients, but relatively to other diseases, such as rheumatoid arthritis (RA), Sjögren's syndrome (SS) and systemic sclerosis (SSc), data has not been systematically evaluated. We conducted a systematic review analysis of the literature in PubMed, including articles published until March of 2015, in patients with RA, SS, SLE and SSc, to evaluate the frequency of HPV infection, cervical dysplasia and cervical cancer, and associated factors, with particular interest on the role of glucocorticoids and immunosuppressive treatment...

Immune-mediated autoinflammatory diseases are occupying an increasingly prominent position among the pantheon of debilitating conditions that afflict mankind. This review focuses on some of the key developments which have occurred since the original description of autoinflammatory disease in 1999, and focuses on underlying mechanisms that trigger autoinflammation. The monogenic autoinflammatory disease range has expanded considerably during that time, and now includes a broad spectrum of disorders, including relatively common conditions such as cystic fibrosis and subsets of systemic lupus erythematosus...
