(Case 1) A 13-years-old female had multiple arthralgia and butterfly rush, when she admitted in our hospital in May 2001. Nephropathy, hemolytic anemia (Hb 6.3 g/dl and direct Coombs 3+) and high titers of antinuclear antibodies and anti-ds-DNA antibody were disclosed and she was diagnosed as systemic lupus erythematosus (SLE). Although combination therapy of PSL 60 mg/day with a steroid pulse ...
Listeria monocytogenes is a facultative intracellular pathogen that secretes the cytolysin listeriolysin O (LLO), which enables the bacteria to cross the phagosomal membrane. L. monocytogenes regulates LLO activity in the phagosome and minimizes its activity in the host cytosol. Mutants that fail to compartmentalize LLO activity are cytotoxic and have attenuated virulence. Here, we showed that ...
An improved method is described for preparing the enzyme which hydrolyzes the polysaccharide acid contained in vitreous humor, umbilical cord, synovial fluid, and the mucoid phase of group A hemolytic streptococci. Preparations have been obtained from pneumococci, group A hemolytic streptococci, Clostridium welchii, and from splenic tissue, which display the same specific activity. Evidence is ...
Vibrio anguillarum is a causative agent of vibriosis in fish. Hemolytic activity has been suggested as a virulence factor by contributing to hemorrhagic septicemia and diarrhea. In order to identify and characterize the hemolysin genes and examine the role of hemolytic activity in virulence, a mini-Tn10Kan mutagenesis clone bank of V. anguillarum was screened. While no hemolysin-negative strain...
OBJECTIVE If pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections is a unique clinical entity, we hypothesized that children meeting diagnostic criteria would have more clinical exacerbations temporally linked to bona fide group A beta-hemolytic streptococcus infection than matched control subjects (chronic tic and/or obsessive-compulsive disorder with no kno...
The intensity of hemolytic anemia has been proposed as an independent risk factor for the development of certain clinical complications of sickle cell disease, such as pulmonary hypertension, hypoxemia and cutaneous leg ulceration. A composite variable derived from several individual markers of hemolysis could facilitate studies of the underlying mechanisms of hemolysis. In this study, we asses...
hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (avr).the mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. it appears to be independent of its severity as assessed by echocardiography. we present a case of a 24-year-old man with a histo...
Objective: To identify the prevalence of group A beta hemolytic streptococcus related pharyngitis in Pakistan. Study Design: Retrospective Place and Duration Study: Department ENT Head & Neck Surgery, Liaquat College Medicine Dentistry, Karachi from 1st July 2021 to 31st March 2022. Methodology: One hundred seventy patients who showed symptoms were enrolled. Two throat swabs taken where fir...
