Management of patients in Germany with suspected viral haemorrhagic fever and other potentially lethal contagious infections

Patients suffering from viral haemorrhagic fevers must be handled specifically. The clinical diagnosis of these diseases in the initial stage is difficult because early symptoms are non specific. In Germany, specific diagnosis is available at two diagnostic centres with biosafety level 4 facilities. Five high security infectious disease isolation units for patient care are available in Munich, Leipzig, Hamburg, Berlin, and Frankfurt. In addition, a corresponding number of centres of competence are established to offer support and advice to the hospitals initially treating the patients and to the local public health officers. The decentralisation of these centres of competence is recommended to allow for more timely and reactive responses to VHF epidemic threats. The risk categorisation for contacts has proved to be very useful in practice.     

Viral haemorrhagic fever in Sweden: experiences from management of a case.

The first recognized case in Scandinavia with potential man to man transmission of viral haemorrhagic fever occurred in Link?ping, Sweden, in January 1990. Following a visit to Kenya a 21-year-old male student suffered a very severe illness including extremely prolonged high grade fever, rash, disseminated intravascular coagulation with thrombocytopenia and severe bleedings. This necessitated one month of intensive care support including respirator treatment. The patient was discharged after 2 1/2 months in good condition, with a partial femoral nerve paresis. About 100 medical personnel were exposed to aerosol or blood before a strict containment regimen was established. No secondary cases occurred.     

Bichat guidelines for the clinical management of haemorrhagic fever viruses and bioterrorism-related haemorrhagic fever viruses

Haemorrhagic fever viruses (HFVs) are a diverse group of viruses that cause a clinical disease associated with fever and bleeding disorder. HFVs that are associated with a potential biological threat are Ebola and Marburg viruses (Filoviridae), Lassa fever and New World arenaviruses (Machupo, Junin, Guanarito and Sabia viruses) (Arenaviridae), Rift Valley fever (Bunyaviridae) and yellow fever, Omsk haemorrhagic fever, and Kyanasur Forest disease (Flaviviridae). In terms of biological warfare concerning dengue, Crimean-Congo haemorrhagic fever and Hantaviruses, there is not sufficient knowledge to include them as a major biological threat. Dengue virus is the only one of these that cannot be transmitted via aerosol. Crimean-Congo haemorrhagic fever and the agents of haemorrhagic fever with renal syndrome appear difficult to weaponise. Ribavirin is recommended for the treatment and the prophylaxis of the arenaviruses and the bunyaviruses, but is not effective for the other families. All patients must be isolated and receive intensive supportive therapy.

Nitritoid reactions: case reports, review, and recommendations for management.

OBJECTIVE: We assessed nitritoid reactions, which are a well recognized side effect of chrysotherapy that occur in roughly 5% of patients taking gold sodium thiomalate (GST). METHODS: Between January 1996 and January 2000, 8 patients followed in our gold monitoring program at Mary Pack Arthritis Centre experienced nitritoid reactions observed by the clinic nurse. We undertook a chart review to determine the risk factors, timing, course, and outcome of nitritoid reactions. RESULTS: Patients' ages ranged from 36 to 69 years, and 7 of 8 were women. Duration of gold therapy prior to nitritoid reactions ranged from 13 months to 13 years. Seven had previously had mucocutaneous reactions, and one experienced gold dermatitis following a nitritoid reaction. Two of 8 patients were taking angiotensin converting enzyme inhibitor agents. Seven reactions were classified as mild, and one was a severe reaction with hypotension, syncope, and angina. CONCLUSIONS: Management includes a high index of suspicion in patients experiencing nausea, flushing, or dizziness following gold injections, switching from GST to gold sodium aurothioglucose, injection in the recumbent position, and observation for 20 minutes after injections in individual patients.     

The outbreak and control of Ebola viral haemorrhagic fever in a Ugandan medical school

Uganda has just experienced the largest outbreak of Ebola haemorrhagic fever (EHF) ever recorded. Mbarara University Teaching Hospital (MUTH) is responsible for training approximately one-third of Uganda's doctors. Mbarara is located in SouthWest Uganda, 614 km from Gulu, the main epicentre of the outbreak. On 23 October a patient was admitted to the medical ward of MUTH with an acute fever. He soon exhibited haemorrhagic symptoms and died. He was later confirmed to have suffered Ebola. Three more patients subsequently contracted the disease. All died. There were no further cases in Mbarara. No members of staff or medical student was infected. We give details of the clinical features of those patients who contracted the disease, the setting up of an Ebola isolation unit, the case surveillance and the search for the source of the outbreak. The implications for similar institutions in East Africa are discussed.     

Filovirus hemorrhagic fever outbreak case management: a review of current and future treatment options

Testing an innovative therapy for filovirus hemorrhagic fever (FHF) in an outbreak setting may be years away. Moreover, beyond anecdotal evidence, little is known about best practice for outbreak case management. Currently, Médecins Sans Frontières and others provide FHF patients with basic supportive treatment. We describe and discuss treatment possibilities, challenges, and potential next steps for FHF outbreak case management. More comprehensive supportive treatment, including vital sign monitoring, intensive care components, and goal-directed interventions may contribute to improved clinical outcome; the feasibility and effectiveness of this more comprehensive supportive treatment should be assessed. Our outlined summary may assist future FHF outbreak case management teams to create collaborative platforms and develop relevant treatment protocols aimed at improving clinical outcome.     

Current management of patients with viral haemorrhagic fevers in the United Kingdom

In the UK, suspected and confirmed cases of viral haemorrhagic fever are currently managed according to the 1996 Guidance of the Advisory Committee on Dangerous Pathogens, which describes an approach to the risk categorisation of suspected cases. It also provides guidance on patient management including transfer, laboratory investigations, infection control, and monitoring of contacts based on the risk assessment. Confirmed cases are managed in bed isolators ("Trexler units"), two of which are available in high security infectious disease units in the UK. This guidance is under review and may change. Recent experience has shown that communication and reassurance for health care workers and the public are major tasks in managing such cases.     

Clinical features of septic discitis in the UK: a retrospective case ascertainment study and review of management recommendations

Septic discitis is a rare but important cause of spinal pain caused by intervertebral disc infection. This retrospective observational case series analysis will examine the clinical features and management of septic discitis in 23 patients and compare with a similar 2001 study. We will also review the evidence behind management recommendations to identify areas for future research. The incidence of septic discitis was 2 per 100,000 per year. Patients presented with spinal pain (96 %), fever (70 %) and raised inflammatory markers. All patients had blood cultures and 52 % had targeted microbiological analysis. Staphylococcus aureus was the most common causative organism (39 %). Treatment was most often with intravenous flucloxacillin or ceftriaxone. CT-guided sampling for culture before commencing antibiotics increased organism detection from 33 to 67 %, and organism identification reduced the antibiotic course from an average of 142 days to 77 days. An increased number of significant co-morbid conditions were associated with worse outcomes. Results broadly resembled the 2001 study. Key differences were increased use and yield of magnetic resonance imaging and computerised tomography (CT) scanning and more frequent use of intravenous antibiotics. Comparisons between the studies suggest that improvements in the consistency of management have been slow. We suggest this due to the large spectrum of disease and the lack of guidelines in the UK. It is widely recommended to perform blood cultures and CT-guided biopsies before starting antibiotics, but it is unclear how long to withhold antibiotics if cultures remain negative. Six weeks of intravenous followed by 6 weeks of oral therapy is often suggested as treatment, whereas some recommend using inflammatory markers to guide antibiotic duration. Larger studies addressing these specific questions are required to provide more definitive guidance for these clinical decisions.     

A case of Crimean-Congo haemorrhagic fever successfully treated with therapeutic plasma exchange and ribavirin

Crimean-Congo haemorrhagic fever (CCHF) has become an important problem in certain parts of the world. Cytokine storm plays a critical role in the pathogenesis of CCHF. Early diagnosis, supportive therapy and invasive monitoring are the cornerstones of the management of CCHF. Ribavirin is active against CCHF virus in vitro, however, evidence of clinical efficacy is still conflicting. Here, we describe a patient successfully recovered from CCHF with a combination of plasma exchange and ribavirin therapy.     

Hospital preparedness and management of patients affected by viral haemorrhagic fever or smallpox at the Lazzaro Spallanzani Institute, Italy

The US cases of anthrax in 2001 and the recent severe acute respiratory syndrome outbreak have heightened the need for preparedness and response to naturally emerging and re-emerging infections or deliberately released biological agents. This report describes the response model of the Istituto Nazionale per le Malattie Infettive Lazzaro Spallanzani (INMI), Rome, Italy for managing patients suspected of or affected by smallpox or viral haemorrhagic fever (VHF) either in the context of an intentional release or natural occurrence. The INMI is Italy's leading hospital in its preparedness and response plan to bioterrorism-related infectious agents. All single and double rooms of INMI are equipped with negative air pressure, sealed doors, high efficiency particulate air (HEPA) filters and a fully-equipped anteroom; moreover, a dedicated high isolation unit with a laboratory next door for the initial diagnostic assays is available for admission of sporadic patients requiring high isolation. For patient transportation, two fully equipped ambulances and two stretcher isolators with a negative pressure section are available. Biomolecular and traditional diagnostic assays are currently performed in the biosafety level 3/4 (BSL 3/4) laboratories. Continuing education and training of hospital staff, consistent application of infection control practices, and availability of adequate personnel protective equipment are additional resources implemented for the care of highly infectious patients and to maintain the readiness of an appropriately trained workforce to handle large scale outbreaks.     

Familial Mediterranean fever with chronic ascites: a case report and a review of literature

Familial Mediterranean fever (FMF) is an autosomal recessive inflammatory disease especially seen in Turks, Sephardic Jews, Armenians, and Arabs. Peritoneal and pleural inflammation, arthritis, erysipelas-like erythema, and arthralgia are well-known features of FMF. A small amount of peritoneal fluid collection can be seen during peritoneal attacks in FMF patients, but chronic ascites is a rather rare complication. We herein report a female FMF patient who developed chronic ascites. She was compound heterozygote for M694V/M680I mutation of the MEFV gene. Aspiration of the ascites fluid revealed a small amount of erythrocytes and mesothelial cells. After dose adjustment of colchicine the amount of ascites decreased. In conclusion, FMF should be considered in the differential diagnosis of chronic ascites in populations where the disease is endemic.     

The effectiveness of a consultation: Compliance with initial recommendations

To identify the attributes of an effective consultation, 202 general medicine consultations were analyzed to assess the extent of compliance with the consultant's initial recommendations. The overall compliance rate was 77 percent. Compliance decreased as the number of recommendations increased. The consultant made more recommendations among patients who had more complex and more severe illnesses. Although compliance did increase significantly in severely ill patients (p < 0.01), with each severity level, compliance was higher when five or fewer recommendations were made. In fact, compliance decreased from 96 percent in severely ill patients with small consultation lists to 79 percent in those with large lists. Compliance was greatest with recommendations involving medications and least with those requiring direct physician and nursing action. Multivariate analysis confirmed that clinical severity of the patients' illnesses and the type and number of recommendations were all predictors of compliance. To promote overall compliance, consultants should limit the total number of recommendations in their initial consultation to five or fewer, focusing on issues central to current patient care. This is especially true in severely ill patients. Since recommendations that must be implemented by physicians or nurses have a lower compliance rate, consultants must carefully follow up those requests.     

Rat-bite fever in children: case report and review

We report 2 cases of rat-bite fever (RBF), a multisystem zoonosis, in children and review the literature. RBF is caused by I of 2 Gram-negative organisms: Streptobacillus moniliformis or, less commonly, Spirillum minus. Both of our cases developed in school-aged girls with a history of rat exposure who presented with a multisystem illness consisting of fever, petechial and purpuric rash, arthralgia and polyarthritis. Both responded promptly to antibiotic treatment. An additional 10 cases from a MEDLINE review (1960-2000) are reviewed. RBF must be included in the differential diagnosis of febrile patients with rashes and a history of exposure to rats.
