Three Autopsy Cases of Non-Meningococcal Waterhouse-Friderichsen Syndrome with Hypoplastic Spleen or Post-Splenectomy Status.

We report three cases of Waterhouse-Friderichsen syndrome (WFS) that were confirmed during forensic autopsies. Case 1 involved a man in his 50s post-splenectomy. Bacteriological examination revealed Streptococcus pneumoniae (S. pneumonia). The patient was considered to have died of asphyxiation after aspirating vomit. Case 2 involved a man in his 40s. Bacteriological examination again revealed S. pneumoniae. Histopathological examination showed hypoplasia of the spleen. This patient was considered to have died of multiple-organ failure due to sepsis, disseminated intravascular coagulation, and WFS. Case 3 involved a post-splenectomy woman in her 60s with a history of systemic lupus erythematosus. Bacteriological examination revealed Streptococcus oralis. This patient was considered to have died of multiple-organ failure due to sepsis, disseminated intravascular coagulation, and WFS. These three cases were included among forensic autopsies conducted in the last 5 years. WFS has been considered a rare disease, but may be more frequent than previously assumed. If a mildly ill patient displays a sudden change in status and dies within a short period of time, we consider it necessary to perform not only bacteriological examinations, but also histopathological examination of the spleen during autopsy.

A case report of spontaneous staphylococcal meningitis in a cynomolgus monkey.

This report describes a suppurative meningitis in a young cynomolgus. The animal had neutrophil aggregation in the subarachnoid space and hemorrhage in bilateral adrenal glands. Staphylococcus was identified by FISH in brain. To our knowledge, this is the first case of staphylococcal meningitis with Waterhouse-Friderichsen syndrome in a cynomolgus monkey.

Streptococcus Pneumoniae Detection Long Time After Death in a Fatal Case of Waterhouse-Friderichsen Syndrome.

We report a fatal case of Waterhouse-Friderichsen syndrome in a 64-year-old man. The diagnosis, suspected during the autopsy (performed 63 hours after death), was confirmed through the successful detection of Streptococcus pneumoniae DNA and antigens in samples (blood and liver) collected during the autopsy. These results conformed with blood cultures performed antemortem, which became available only the day after the autopsy. The case underlines the need to collect biological material (liver and blood samples) during autopsy for microbiological investigations, although the collection is performed a long time after the death, suggesting that a liver sample works for DNA and liver and blood work for Streptococcus pneumoniae antigen detection.

Waterhouse-Friderichsen syndrome, septic adrenal apoplexy.

Waterhouse-Friderichsen syndrome is a rare but potentially fatal disorder of the adrenal gland characterized by bilateral adrenal hemorrhage. It is classically a result of meningococcal sepsis and presents acutely with features of shock, petechial rashes, abdominal pain, and non-specific symptoms such as headache, fatigue, and vomiting. Treatment consists of fluid resuscitation, corticosteroid replacement, and possibly surgery. The prognosis is poor despite treatment. This chapter will review the etiology, pathogenesis, clinical features, and management of the disease.

Waterhouse-Friderichsen Syndrome with Bilateral Adrenal Hemorrhage Associated with Methicillin-Resistant Staphylococcus aureus (MRSA) Bacteremia in an Adult Patient with History of Intravenous Drug Use.

BACKGROUND Waterhouse-Friderichsen syndrome, also known as acute adrenal insufficiency due to adrenal gland hemorrhage, is an uncommon and frequently fatal condition classically presenting with fever, shock, rash, and coagulopathy. Although most often associated with Meningococcemia, many other etiologies have been implicated, including reports of Staphylococcus aureus infection on autopsy examinations. This report details an adult intravenous drug user with adrenal hemorrhage associated with methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. CASE REPORT A 58-year-old man with a history of intravenous drug use presented to the hospital with weakness. Vitals were initially normal and exam findings were notable for decreased right-sided motor strength. Magnetic resonance imaging (MRI) revealed a cervical epidural abscess with spinal cord compression. Despite initiation of broad-spectrum antibiotics and intravenous fluids, the patient progressed to shock, requiring vasopressor administration, and his blood cultures later grew MRSA. Further imaging of the abdomen/pelvis was completed, revealing bilateral adrenal hemorrhage. Random cortisol at that time was 5.6 µg/dL, confirming a diagnosis of critical illness-related corticosteroid insufficiency in addition to likely septic and spinal shock. The patient was initiated on hydrocortisone with improvement in his hypotension. He was transitioned to prednisone and fludrocortisone in addition to 8 weeks of antibiotics after achieving clinical stability. CONCLUSIONS This report brings to attention the risk of adrenal hemorrhage and acute adrenal insufficiency as a sequela of the relatively common illness of Staphylococcus aureus bacteremia. As symptoms of adrenal insufficiency can overlap with septic shock related to the primary condition, this diagnosis requires a high index of suspicion in the critically ill patient.

Fatal Waterhouse-Friderichsen syndrome in an adult due to serogroup Y Neisseria meningitidis.

Waterhouse-Friderichsen syndrome (WFS), defined as severe adrenal insufficiency due to bilateral adrenal gland haemorrhagic necrosis, occurred in a 59-year-old woman. An underlying serogroup Y Neisseria meningitidis (NM) infection was diagnosed, with a rapid progression to purpura fulminans, disseminated intravascular coagulation and WFS. Intensive treatment including fluid resuscitation, broad-spectrum antibiotic therapy, ventilatory support, platelet and factor replacement were administered. The meningococcaemia in the presence of WFS had a fulminant progression, leading to a fatal outcome within 24 hours of symptom onset. This case details the diagnosis and management challenges of the WFS, a rare complication of NM septicaemia, and describes the identification of a NM serogroup that is rare in Portugal in middle-aged patients.

[The Waterhouse-Friderichsen syndrome]. / Het syndroom van Waterhouse-Friderichsen.

BACKGROUND: The Waterhouse-Friderichsen syndrome (WFS) is a serious illness associated with a high mortality rate and characterized by septic shock and signs of adrenocortical insufficiency. CASE DESCRIPTION: A 33-year-old male was seen in the emergency department with severe abdominal and back pain with diffuse mottled skin and rapidly progressive petechiae all over his body. Laboratory results showed severe lactate acidosis with renal dysfunction and indications of diffuse intravascular coagulation. Because he had signs of progressive septic shock, the patient was admitted to the ICU. There he subsequently developed hypoglycaemia (glucose < 0.1 mmol/l) and CPR had to be performed twice - the patient died shortly afterwards. Autopsy showed bilateral necrosis and haemorrhage of the adrenal glands, indicative of the diagnosis of WFS. Streptococcus pneumoniae was identified. CONCLUSION: In case of sepsis, with fever, rapidly expanding petechiae and purpura the Waterhouse-Friderichsen syndrome should be considered. Intensive therapy with antibiotics, fluids, vasopressors, and corticosteroids should be initiated immediately.

A rare case of Waterhouse- Friderichsen syndrome during primary Varicella zoster infection.

Primary Varicella zoster virus infection in adults is associated with a higher risk of complications when compared with the benign disease course of primary infection during childhood. We present a rare complication of adult primary Varicella zoster in the form of acute, irreversible adrenal insufficiency due to bilateral adrenal haemorrhage, which is also known as the WaterhouseFriderichsensyndrome.

[Waterhouse-Friderichsen cases in the archives of ZMS PAM--epidemiological conditions and diagnostic difficulties]. / Przypadki zespolu Waterhouse'a-Friderichsena w materialach ZMS PAM--uwarunkowania epidemiologiczne oraz trudnosci diagnostyczne.

15 cases of meningococcal infections from 2003-2004 were discussed in the study. Their therapy ended in failure and they had been typically autopsied in our Forensic Med. Department. During the autopsy material for classical microbiological investigations was collected. That type of death is characterised with pathognomonic and autopsy image. The problem is the microbiological identification of the pathogen group and type. It is connected with the characteristic of the analysed material and the biological features of Neisseria meningitidis. The molecular and genetic methods show their usefulness in this type of diagnostic of the properly selected and collected material which typically are: cerebrospinal fluid, brain tissue with the arachnoid membranes and spleen tissue.

Waterhouse-Friderichsen syndrome as a result of non-meningococcal infection.

Waterhouse-Friderichsen syndrome--massive adrenal haemorrhage in the setting of overwhelming clinical sepsis--is usually taken at necropsy to indicate meningococcal infection, and may be the only evidence of this pathogen. This report describes three fatal cases of the syndrome in which the causative organism proved to be a streptococcus. The organisms were detected during routine coroners' autopsies with histology and microbiological investigations. In two cases, the syndrome followed Streptococcus pneumoniae infection and in a third beta haemolytic streptococcus group A. Thus, adrenal haemorrhage alone cannot be taken to indicate meningococcal disease and other pathogens, particularly streptococcus, must be considered.

The protective effect of brachial plexus palsy in purpura fulminans.

Acute infectious purpura fulminans is reported in a 16-month-old male with a history of posttraumatic asplenia and complete left brachial plexus palsy. This patient developed peripheral necrosis of both lower extremities and the right upper extremity, whereas the left upper extremity was completely spared from ischemia and tissue damage. Amputation of four digits on the right hand and debridement of both lower extremities were required. This patient demonstrated the protective effect of a traumatic sympathectomy, which suggests the requirement of an intact sympathetic reflex in the development of purpura fulminans.

Waterhouse-Friderichsen syndrome secondary to Capnocytophaga canimorsus septicemia and demonstration of bacteremia by peripheral blood smear.

Waterhouse-Friderichsen syndrome caused by Capnocytophaga canimorsus septicemia was fatal in a previously healthy 47-year-old woman. The patient died suddenly in less than 12 hours after presentation, in spite of supportive measures, including ventilation, antibiotic coverage, pressor therapy, and multiple transfusions of blood products. The diagnosis of infection due to an unusual organism was suspected earlier in the course of management after review of the peripheral blood smear. The importance of the findings in the blood smear and their correlation with infection due to this organism are discussed.

Rupert Waterhouse and Carl Friderichsen: adrenal apoplexy.

The Waterhouse-Friderichsen (WFS) syndrome, also known as purpura fulminans, is described as acute hemorrhagic necrosis of the adrenal glands and is most often caused by meningococcal infection. This clinical entity is more frequently seen in the pediatric than the adult population and is associated with a high morbidity and mortality. The initial presenting complaints for patients with the WFS usually include a diversity of nonspecific, vague symptoms such as cough, dizziness, headache, sore throat, chills, rigors, weakness, malaise, restlessness, apprehension, myalgias, arthralgias, and fever. These symptoms are usually abrupt in their onset. Petechiae are present in approximately 50-60% of patients. The clinical diagnosis of WFS may be relatively straightforward or extremely challenging. Patients who appear in the initial and nontoxic-appearing stage without any skin lesions may be difficult to distinguish from a benign viral illness. When a patient presents with fever and petechiae, WFS must be considered, even when the patient has a non-toxic appearance. Due to the rapid progression and often devastating consequences, therapy should be instituted as soon as the diagnosis is suspected.

Sepsis-associated purpura fulminans in adults.

Sepsis-associated purpura fulminans is defined as septicemia, shock, disseminated intravascular coagulation and circulatory failure leading to multiple organ dysfunction. 40-70% of patients with sepsis-associated purpura fulminans die. Early prognostic factors in adults have not been well delineated yet. Aim of our study was 1) to evaluate currently used scoring systems for meningococcal septicemia in the setting of sepsis-associated purpura fulminans and 2) to assess if other parameters are feasible as early prognostic factors. From 1.1 1994-31.12.1998 twelve patients (female: 7; mean age: 31 (21; 43) years) were studied. Six patients (50%) died within 2 hours and 7 days after admission despite standard intensive treatment. On admission non-survivors had a more pronounced degree of disseminated intravascular coagulation compared to survivors (platelet count 18000 (15000; 45000) G/l vs. 119.000 (111000; 152000) G/l, (p = 0.03); fibrinogen 67 (50; 108) mg/dl vs. 356 (234; 483) mg/dl, (p = 0.02); PTZ 28% (20%; 30%) vs. 44% (35%; 51%), (p = 0.05); aPTT 120 (120; 128) sec vs. 46 (44; 69) sec, (p = 0.001). Severity of lactic acidosis was significantly higher in non-survivors than in survivors (pH 7.08 (6.92; 7.21) vs. pH 7.4 (7.25; 7.4), (p = 0.02); lactate 13.5 (11; 15) mval/l vs. 6.0 (4.4; 6) mval/l, (p = 0.02); data presented as median (25-75% interquartile range). In our patients the Glasgow Meningococcal Septicemia Prognostic Score (GMSPS) and the Niklasson-Score failed to distinguish between survivors and non-survivors (GMSPS 7 (6; 11) vs 7.5 (7; 9) out of 15; predicted mortality according to Niklasson-Score 73% vs 88%). There was no difference in the APACHE II Score (22 (18.5, 24) vs 22 (20.25, 26)). The severity of disseminated intravascular coagulation assessed by routine laboratory parameters and the degree of lactic acidosis on admission were the strongest predictors of outcome in patients with sepsis-associated purpura fulminans. Scoring systems developed for patients with meningococcal septicemia are of limited value in the setting of sepsis-associated purpura fulminans.

[Recombinant human activated protein C in the treatment of children with meningococcal purpura fulminans]. / Proteína C activada humana recombinante en el tratamiento de niños con púrpura fulminante meningocócica.

Meningococcal purpura fulminans (MPF) produces high mortality and morbidity, despite appropriate standard therapy. Administration of recombinant human activated protein C (rhAPC) has been successfully applied in adults with MPF and pediatric studies are under way. We report three pediatric patients with MPF treated with rhAPC as compassionate therapy. In two of these patients, positive clinical and laboratory effects were observed and both children achieved full recovery. The remaining patient died after 36 hours from refractory multiorgan failure. No rhAPC-related adverse effects were detected. The reported cases highlight the usefulness of rhAPC in children with MPF at least as a rescue compassionate treatment. Further clinical trials are needed to better delineate its efficacy and administration schedule in children.
