Neonatal lupus (NL) is a very rare condition with an estimated incidence of 1 in 20.000 pregnancies. It is caused by the transplacental passage of autoantibodies anti-Ro/SSA, antiSa/SSB antibodies and/or anti-U1 RNP antibodies into the fetal circulation. The mother may be completely asymptomatic or have a known inflammatory rheumatic disease, such as Sjögren syndrome (SS) or Systemic Lupus Erythematosus (SLE). Clinical manifestations are diverse, being the most common cutaneous and cardiac. The authors present a case series of eight cases diagnosed with NL between January 2008 and December 2016 in a tertiary hospital and a brief revision of the literature...

Proton pump inhibitors are among the most commonly used drugs worldwide. They are considered to be largely safe and cause little side-effects. We report a 69-year-old woman who suffered from erythematous plaques 2 months after initiating therapy with esomeprazole. The diagnosis of subacute cutaneous lupus erythematosus was based on the clinical picture together with characteristic histological features of a skin biopsy specimen and the detection of anti-Ro/SSA antibodies. In particular, the temporal relationship with the onset of proton pump inhibitor therapy led to the high-level suspicion of a drug-induced pathogenesis...

OBJECTIVE: To assess esophageal involvement (EI) in juvenile localized scleroderma (JLS) population and the possible association between this gastrointestinal manifestation and demographic data, clinical features, laboratory exams, treatments and outcomes. METHODS: For a period of 30 years, 5881 patients with rheumatic diseases were followed in our Pediatric Rheumatology Division. EI was defined by the presence of symptoms (solid/liquid dysphagia, heartburn, esophageal regurgitation, nausea/vomiting and epigastralgia) and confirmed by at least one EI exam abnormality: barium contrast radiography, upper gastrointestinal endoscopy and 24-hour esophageal pH-monitoring...

Background/Aims: To evaluate cellular immune function in systemic lupus erythematosus (SLE) patients over 60 years old, the association between antinuclear antibody (ANA) titers and the ratio of CD4+ /CD8+ was analyzed in this study. The distribution of ANAs and extractable nuclear antibodies (ENAs) in a healthy elderly population was also investigated. Methods: Serum ANA titers were assayed by indirect immunofluorescence (IIF) and the CD4+ /CD8+ T-cell ratio was determined by flow cytometry in 76 SLE patients and 30 healthy control individuals...

BACKGROUND: Approximately 8% of HIV-infected individuals are co-infected with hepatitis B virus (HBV) in sub-Saharan Africa (SSA). Knowledge of HBV status is important to guide optimal selection of antiretroviral therapy (ART) and monitor/prevent liver-related complications. We describe changes in testing practices and management of HBV infection over a 3-year period in HIV clinics across SSA. METHODS: A medical chart review was conducted in large urban HIV treatment centers in Côte d'Ivoire (3 sites), Benin, Burkina Faso, Cameroon, Kenya, Senegal, South Africa, Togo, Uganda and Zambia (1 site each)...

Thrombotic thrombocytopenic purpura (TTP) is a potentially lethal multisystem disorder which could be caused by autoimmune diseases. However, the concomitant occurrence of TTP and Sjögren's syndrome (SS) is an extremely uncommon scenario, especially in male patients. A 56-year-old Chinese male was admitted for the appearance of diffuse ecchymosis. Then he gradually developed transient slurred speech, progressive confusion, agitation, extremity weakness, and fever. Laboratory investigations suggested anemia, thrombocytopenia, significantly increased lactic dehydrogenase, schistocytes in peripheral blood smear, and a disintegrin-like metalloproteinase with thrombospondin motif type 1 member 13 (ADAMTS13) activity deficiency with high inhibitor titers...

This case report describes a patient with scleroderma who developed Mycobacterium intracellulare infection, which for more than a year mimicked worsening of her connective tissue disorder. The patient was diagnosed with scleroderma based on puffy fingers that developed into sclerodactyly, abnormal nail fold capillaries, interstitial lung disease, Raynaud's phenomenon, esophageal dysmotility, and positivity for rheumatoid factor and anti-SSA antibodies. She developed massive inflammatory changes of the cutis, the subcutis, and the muscle fasciae of the right leg, that after several failed attempts of immunosuppressive treatments were found to be caused by Mycobacterium intracellulare...

We investigated the correlation between the increased proportion of peripheral B cell subsets and clinical and immunological features in primary Sjögren's syndrome (pSS). We found that the proportion of CD19(+) B cells was significantly increased in pSS as compared with HC and was correlated with serum IgG levels. Moreover, in vitro IgG production by CD19(+) B cells was significantly increased in pSS and was positively and significantly correlated with serum IgG levels. FACS analysis revealed that the proportions of peripherally CD38(high)IgD(+) B cells and CD38(high)IgD(-) B cells were significantly increased in pSS...

OBJECTIVE: Fetal exposure to maternal anti-SSA/Ro antibodies is necessary but not sufficient for the development of autoimmune congenital heart block (CHB), suggesting that other factors, such as fetal genetic predisposition, are important. Given the previously described association between major histocompatibility complex alleles and CHB risk, we undertook the present study to test the hypothesis that a variant form of HLA-C Asn80Lys, which binds with high affinity to an inhibitory killer cell immunoglobulin-like receptor (KIR) and thus renders natural killer (NK) cells incapable of restricting inflammation, contributes to the development of CHB...

Maternal autoantibodies to Ro/SSA are often linked to congenital heart block and rarely associated with structural defects. We describe the case of a fetus with anti-Ro-mediated second-degree block at 19 weeks, which progressed to a complete block, fibroelastosis, atrioventricular valve insufficiency, and semilunar valve stenosis/insufficiency at 20, 22, 24, and 26 weeks, respectively, although the fetus received transplacental anti-arrhythmic drugs. The 2150-g fetus was vaginally delivered at 35 weeks. An external pacemaker was inserted immediately after birth and replaced with permanent pacemaker at the age of 3 months...

Objectives: Congenital heart block (CHB) develops in 1-2% of anti-Ro/SSA-positive pregnancies and has a recurrence rate of 12-20%, which indicates that factors other than maternal autoantibodies are crucial for CHB to occur. Here, we aimed to evaluate the influence of factors previously associated with CHB on the occurrence of milder forms of fetal cardiac conduction disturbances, shown to occur in up to 30% of anti-Ro/SSA-positive pregnancies, and on neonatal outcome in a large cohort of prospectively followed pregnancies...

OBJECTIVES: Congenital heart block (CHB) occurs in 1%-2% of anti-Ro/SSA antibody-positive pregnancies. A population-based recurrence rate of 12% indicates that factors other than maternal autoantibodies influence CHB development. Here we report the first investigation to identify environmental and lifestyle factors influencing the risk of CHB. METHODS: A questionnaire focused on environmental and lifestyle factors was distributed to anti-Ro/SSA antibody-positive women who had given birth to at least one child with CHB, and additional data were retrieved from national health registers...
