Anthrax is still an endemic disease in some countries in the world and has become a re-emerging disease in western countries with recent intentional outbreak. The aim of this study was to review our clinical experience with cutaneous anthrax cases. From the patient's files, transmission of the diseases, clinical findings and severity of infection, treatment and outcome of patients were recorded. Twenty-two cases were diagnosed as cutaneous anthrax in the last 7 years. Of these cases, 10 cases were severe form of cutaneous anthrax, 10 cases were mild form and 2 cases were toxemic shock due to cutaneous anthrax. The incubation period was between 1 and 17 days. The main clinical characteristics of the cases with severe cutaneous anthrax were fever, hemorrhagic bullous lesions surrounded by an extensive erythema and edema, and leukocytosis. Two cases with toxemic shock had low systolic blood pressure, apathy and toxemic appearance, leukocytosis, hypoalbuminemia & hyponatremia. Penicillin G was given in 15 cases, amoxicillin in 4 and other antibiotics in 3 cases for 3-10 days. Skin lesion left deep tissue scar in 4 cases and were grafted. Physicians working in endemic areas and also in western countries should be aware of all clinical forms of anthrax.
"Seroreactivity to PA63 could also be observed in people who have been infected with Bacillus anthracis and survived. Since pulmonary and gastrointestinal Anthrax is usually fatal or debilitating, and since cutaneous Anthrax results in a characteristic black eschar, it is unlikely that prior Anthrax would be missed on a directed health questionnaire –. Thus, positive immune reactivity to PA63 would strongly suggest non-specific interaction of host antibodies with PA63 or prior exposure to an antigen with a shared epitope. We thus excluded samples that showed immunoreactivity against ETX and PA63 since these indicated equivocal results. "
[Show abstract][Hide abstract] ABSTRACT: We have isolated Clostridium perfringens type B, an epsilon toxin-secreting bacillus, from a young woman at clinical presentation of Multiple Sclerosis (MS) with actively enhancing lesions on brain MRI. This finding represents the first time that C. perfringens type B has been detected in a human. Epsilon toxin's tropism for the blood-brain barrier (BBB) and binding to oligodendrocytes/myelin makes it a provocative candidate for nascent lesion formation in MS. We examined a well-characterized population of MS patients and healthy controls for carriage of C. perfringens toxinotypes in the gastrointestinal tract. The human commensal Clostridium perfringens type A was present in approximately 50% of healthy human controls compared to only 23% in MS patients. We examined sera and CSF obtained from two tissue banks and found that immunoreactivity to ETX is 10 times more prevalent in people with MS than in healthy controls, indicating prior exposure to ETX in the MS population. C. perfringens epsilon toxin fits mechanistically with nascent MS lesion formation since these lesions are characterized by BBB permeability and oligodendrocyte cell death in the absence of an adaptive immune infiltrate.

"If not promptly treated with antibiotics such as penicillin, anthrax can result in the death of 10–40% of patients and is fatal within as few as 24 h . The most common of the three forms of this disease is cutaneous—with respiratory and gastrointestinal being the other two—having as clinical manifestations increased body temperature, and bullous lesions resulting in severe erythema, edema, and tissue necrosis [6, 7].

[Show abstract][Hide abstract] ABSTRACT: It has been recorded that one of the possible causes that eventually escalated into the 1857 manslaughter at Mountain Meadows in Southern Utah was the poisoning of an open spring by the Fancher–Baker party as they crossed the Utah territory on their way from Arkansas to California. Historical accounts report that a number of cattle died, followed by human casualties from those that came in contact with the dead animals. Even after the Arkansas party departed, animals continued to perish and people were still afflicted by some unknown plague. Proctor Hancock Robison, a local 14-year-old boy, died shortly after skinning one of the “poisoned” cows. A careful review of the historical records, along with the more recent scientific literature, seems to exclude the likelihood of actual poisoning in favor of a more recent theory that would point to the bacterium Bacillus anthracis as the possible cause of human and animal deaths. In order to test this hypothesis, Proctor’s remains were exhumed, identified through mitochondrial DNA analysis, and tested for the presence of anthrax spores. Although preliminary testing of remains and soil was negative, description of the clinical conditions that affected Proctor and other individuals does not completely rule out the hypothesis of death by anthrax.

"Systemic anthrax infection is associated with high mortality rates with 45% of patients with inhalation anthrax ultimately dying from the infection [17,18]. Cutaneous anthrax infection, however, is not associated with high mortality rates . "
[Show abstract][Hide abstract] ABSTRACT: In 2000, Ringertz et al described the first case of systemic anthrax caused by injecting heroin contaminated with anthrax. In 2008, there were 574 drug related deaths in Scotland, of which 336 were associated with heroin and or morphine. We report a rare case of septicaemic anthrax caused by injecting heroin contaminated with anthrax in Scotland.
A 32 year old intravenous drug user (IVDU), presented with a 12 hour history of increasing purulent discharge from a chronic sinus in his left groin. He had a tachycardia, pyrexia, leukocytosis and an elevated C-reactive protein (CRP). He was treated with Vancomycin, Clindamycin, Ciprofloxacin, Gentamicin and Metronidazole. Blood cultures grew Bacillus anthracis within 24 hours of presentation. He had a computed tomography (CT) scan and magnetic resonance imagining (MRI) of his abdomen, pelvis and thighs performed. These showed inflammatory change relating to the iliopsoas and an area of necrosis in the adductor magnus.He underwent an exploration of his left thigh. This revealed chronically indurated subcutaneous tissues with no evidence of a collection or necrotic muscle. Treatment with Vancomycin, Ciprofloxacin and Clindamycin continued for 14 days. Negative Pressure Wound Therapy (NPWT) device was applied utilising the Venturi™ wound sealing kit. Following 4 weeks of treatment, the wound dimensions had reduced by 77%.
Although systemic anthrax infection is rare, it should be considered when faced with severe cutaneous infection in IVDU patients. This case shows that patients with significant bacteraemia may present with no signs of haemodynamic compromise. Prompt recognition and treatment with high dose IV antimicrobial therapy increases the likelihood of survival. The use of simple wound therapy adjuncts such as NPWT can give excellent wound healing results.
