Toxoplasma gondii is a zoonotic protozoan parasite that infects a wide range of warm-blooded animals throughout the world. In the present study, antibodies to T. gondii were determined using a commercial indirect hemagglutination (IHA) test in wild animals in a zoo. Three of 11 giraffes (Giraffa camelopardalis) (27%), 1 of 5 wolves (Canis lupus laniger) (20%), 1 of 6 hippopotamuses (Hippopotamus amphibious) (17%), and 2 of 9 tundra swans (Cygnus columbianus) (22%) were found to be positive. No antibodies were detected in leopards (Panthera pardus), wild geese (Anser cygnoides), and Eastern grey kangaroos (Macropus giganteus)...

OBJECTIVE: To investigate the nationwide prevalence and incidence of serious infections among children with systemic lupus erythematosus (SLE) enrolled in Medicaid, the U.S. health insurance program for low-income patients. METHODS: From Medicaid claims (2000-2006) we identified children 5 to <18 years old with SLE (≥3 ICD-9 codes of 710.0, each >30 days apart) and lupus nephritis (LN; ≥2 ICD-9 codes for kidney disease on/after SLE codes). From hospital discharge diagnoses, we identified infection subtypes (bacterial, fungal, viral)...

Complement system homeostasis is important for host self-protection and anti-microbial immune surveillance, and recent research indicates roles in tissue development and remodelling. Complement also appears to have several points of interaction with the blood coagulation system. Deficiency and altered function due to gene mutations and polymorphisms in complement effectors and regulators, including Factor H, have been associated with familial and sporadic autoimmune inflammatory - thrombotic disorders, in which autoantibodies play a part...

There is a surprisingly scarce amount of epidemiological and molecular data on the prevalence, frequency, and diversity of the intestinal protozoan parasites Giardia duodenalis and Cryptosporidium spp. in wildlife in general and mesocarnivore species in particular. Consequently, the extent of the cyst/oocyst environmental contamination attributable to these wild host species and their potential implications for public veterinary health remain largely unknown. In this molecular epidemiological survey a total of 193 individual faecal samples from badgers (Meles meles, n=70), ferrets (Mustela putorius furo, n=2), genets (Genetta genetta, n=6), Iberian lynxes (Lynx pardinus, n=6), beech martens (Martes foina, n=8), mongooses (Herpestes ichneumon, n=2), otters (Lutra lutra, n=2), polecats (Mustela putorius, n=2), red foxes (Vulpes vulpes, n=87), wildcats (Felis silvestris, n=2), and wolves (Canis lupus, n=6) were obtained from road-killed, hunted, and accidentally found carcasses, and from camera-trap surveys or animals entering rescue shelters, during the period December 2003-April 2016...

Lymphopenia is frequent in systemic lupus erythematosus (SLE) and profound (<500/mm(3)) in 10% of cases. T lymphocytes, especially CD4+, are more affected than B cells. The pathophysiological mechanisms are complex, involving lymphocytotoxic antibodies, excess of apoptosis, increased susceptibility of T cells to complement mediated cytolysis, as well as lymphopoiesis impairment and lymphocyte sequestration. Lymphopenia in SLE is independent from other cytopenia and immunosuppressive drug regiments, and associated with disease activity, risk of flare and damage scores...

To better clarify the clinical features and therapeutic strategy of CMV infection in lupus nephritis patients, we retrospectively surveyed a total of 40 lupus nephritis patients, who had been hospitalized and underwent renal biopsy and diagnosed as having CMV infection during their hospitalization at our institution within the last 10 years. The percentage of CMV infections in the entire hospitalized lupus nephritis population was 5.3% (40/755). The principal clinical features of the 40 CMV-infected patients were hematological disorders (n = 25), fever (n = 21), liver dysfunction (n = 19), and respiratory symptoms (n = 12)...

Cutaneous adverse drug reactions are among the most common noninfectious rashes of childhood. Cutaneous adverse drug reactions are classified as morbilliform, urticarial, bullous, pustular, or psoriasiform. Atopic dermatitis is one of the most common inflammatory cutaneous eruptions, and is characterized by pruritus and flexural distribution. Emollients and topical corticosteroids are first-line therapies. Topical calcineurin inhibitors are second-line, steroid-sparing drugs for certain conditions, such as face and eyelid eczema...

Neutrophils have a significant yet controversial role in the innate immune response to Mycobacterium tuberculosis (M. tb) infection, which is not yet fully understood. In addition to neutrophils' well-known effector mechanisms, they may also help control infection of M. tb through the formation of neutrophil extracellular traps (NETs), which are thought to further promote the killing of M. tb by resident alveolar macrophages. Cytokines such as IFN-γ have now been shown to serve an immunomodulatory role in neutrophil functioning in conjunction to its pro-inflammatory function...

It is currently believed that autoimmune conditions are triggered and aggravated by a variety of environmental factors such as cigarette smoking, infections, ultraviolet light or chemicals, as well as certain medications and vaccines in genetically susceptible individuals. Recent scientific data have suggested a relevant role of these factors not only in systemic lupus erythematosus, but also in cutaneous lupus erythematosus (CLE). A variety of environmental factors have been proposed as initiators and exacerbators of this disease...

OBJECTIVES: Pneumocystis jiroveci pneumonia (PJP) is an opportunistic infection with high mortality among patients with underlying rheumatologic conditions. Given the paucity of prospective data to guide treatment, clinical guidelines to initiate PJP prophylaxis are based on expert opinion and identify patients on ≥20 mg daily prednisone for ≥4 weeks duration for treatment. Herein we describe the PJP experience in rheumatic disease over a 20-year period at a single academic medical centre to investigate this 20 mg threshold and risk associated with lymphocyte counts, co-existing lung disease and immunosuppressive medications...

Nearly 20% of SLE corresponds to the pediatric population, and 75% of them have kidney involvement representing an important etiology of chronic kidney disease. A correlation between SLE and ANCA-associated vasculitis has been identified as an overlapping syndrome. Kidney allograft recurrence is rare in SLE when disease control is achieved and with nowadays immunosuppression treatment. Histologic transformation is unusual, especially when there are negative serologic markers and no immune complex deposition reported in native kidneys...

During the last decade, the development of large clinical and population-based cohorts led to new findings in the epidemiology and the pharmacoepidemiology of immune thrombocytopenia (ITP). The incidence is estimated to 3-4 for 10(5) inhabitants/year, with a slight female predominance and peaks in children and patients after 60 years. The incidence rate is 9 for 10(5) inhabitants/year in males after 75 years. Variations across ethnic groups are discussed. In France, there is a North-South gradient and a peak of incidence during winter suggesting the role of viruses in ITP pathophysiology...

The recent recolonisation of the Central European lowland (CEL) by the grey wolf (Canis lupus) provides an excellent opportunity to study the effect of founder events on endoparasite diversity. Which role do prey and predator populations play in the re-establishment of endoparasite life cycles? Which intrinsic and extrinsic factors control individual endoparasite diversity in an expanding host population? In 53 individually known CEL wolves sampled in Germany, we revealed a community of four cestode, eight nematode, one trematode and 12 potential Sarcocystis species through molecular genetic techniques...
