The surgical strategy of Purpura fulminans triggered by pyothorax associated with lung cancer

Purpura fulminans is a rare disease that usually causes sepsis and is accompanied by disseminated intravascular coagulation and symmetric gangrene of distal extremities. We had to consider the most appropriate surgery approach. The most important point was attempting to rescue the patient’s ability to walk under his own power.

Uncommon Location of Purpura Fulminans: Case Report and Literature Review

Purpura fulminans is a critical, mostly fatal, thrombotic syndrome that requires urgent intervention. Purpura fulminans is an acute purpuric rash characterized by coagulation of the microvasculature, which leads to purpuric lesions and skin necrosis. In this report, we present a rare case of an adult patient who was admitted with rapidly forming purpura fulminans in an uncommon location.

[Diagnosis and management of early-onset thrombophilia/thrombosis: a review]

Evidence of the molecular epidemiology of thrombophilia is growing, and the clinical management of adult thromboembolism patients has recently made significant progress. On the other hand, there is little or no evidence concerning the genetic variation, treatment, and prophylaxis of thromboembolism development in the early life stage. The clinical presentation of early-onset thrombosis/thrombophilia, which mostly occurs in newborns and adolescents, differs from that in cases of adult-onset. Recurrent purpura fulminans and/or intracranial hemorrhage/infarction leads to dangerous lifelong complications. As in the setting of cancer genomic medicine, germline variants require determination for the individualized control of early-onset thrombophilia. The genetic predisposition to thrombosis varies among ethnicities. In the Japanese population, the protein S variant (PS-Tokushima, K196E) has attracted attention as the cause of a common and low-risk prothrombotic predisposition in adults, while protein C deficiency greatly impacts the onset of pediatric thrombosis. In 2020, 3 years after the registration of idiopathic thrombosis as a designated intractable disease, genetic tests have been promulgated for health insurance portability. Disease-specific therapy for early-onset thrombophilia is crucial. Here, we review the genetic heterogeneity, prophylaxis, and treatment strategy of the rare subgroups of severe heritable thrombosis conditions in Japan.

Purpura Fulminans: a Rare but Fierce Presentation of Pneumococcal Sepsis

Infectious purpura fulminans (PF) is a rare presentation of disseminated intravascular coagulopathy (DIC) due to diffuse intravascular thrombosis and haemorrhagic infarction of the skin. PF can present in infancy/childhood or adulthood and usually presents as ecchymotic skin lesions, fever and hypotension. It is most commonly a consequence of sepsis related to Neisseria meningitidis, Streptococcus pneumoniae or Haemophilus influenzae. Despite aggressive management of sepsis with intravenous fluids, antibiotics, and conventional and nonconventional therapies, the condition still carries a mortality rate of 43%^[1]. Streptococcus pneumoniae mostly presents with community-acquired pneumonia. We present a case of PF secondary to DIC related to Pneumococcal sepsis in an otherwise healthy and immunocompetent patient.

Fulminant Neisseria meningitidis septicaemia with purpura fulminans requiring limb amputation

Despite the isolation of Neisseria meningitidis over 200 years ago, meningococcal disease remains a feared cause of bacterial sepsis, with significant morbidity and mortality, despite prompt antibiotic use and modern critical care support. Neisseria meningitides is a Gram-negative encapsulated diplococcus, which exists only in the human host (Kvalsvig and Unsworth, 2003). The bacterium can cause life-threatening septic shock and coagulopathy, which may rapidly manifest within a matter of hours from preceding mild symptoms (Kvalsvig and Unsworth, 2003). Whilst N. meningitidis is recognised as a common commensal organism in the nasopharynx, associated with asymptomatic carriage in up to 10 %, manifestation of life-threatening disease is rare (Rappuoli and Pizza, 2015). We report the case of 31-year-old male presenting with devastating meningococcal septicaemia with disseminated intravascular coagulopathy (DIC) and purpura fulminans, requiring surgical debridement and a right above-knee amputation for sepsis-driven skin necrosis. The patient suffered extensive tissue loss secondary to a type 3 immune hypersensitivity reaction involving immune-complex mediated inflammation and tissue necrosis. Due to a strong immune component driving the patient’s failure to convalesce pulsed intravenous methylprednisolone was used alongside antimicrobial therapy. The use of steroids was associated with fever subsidence and significant clinical improvement, highlighting the benefit of corticosteroid use in immune-complex mediated pathology.

[Inflammatory myopathy following acute meningoccemia in a properdin-deficient patient: A case report]

INTRODUCTION

Myalgia is a classical sign in invasive meningococcal diseases (IMD), but severe and persistent myalgia following an IMD have never been reported to date.

CASE REPORT

A 20-year-old man presented with purpura fulminans and meningitis caused by Neisseria meningitidis serogroup Y, revealing properdin deficiency. Although meningitis symptoms improved after antibiotherapy, initial myalgia of the lower limbs increased, associated with mild rhabdomyolysis. Magnetic resonance imaging (MRI) revealed an increased STIR (Short TI inversion recovery) signal of both quadriceps muscles, without abscess. After exclusion of other causes of myopathy, a post-infectious myositis was diagnosed. A four-week course of corticosteroids led to dramatic improvement.

CONCLUSION

Post-infectious inflammatory myopathy should be suspected in case of severe and persistent myalgia associated with rhabdomyolysis following an IMD, after exclusion of pyomyositis especially. A short course of corticosteroids seems to be effective.

Surgical outcomes in adults with purpura fulminans: a systematic review and patient-level meta-synthesis

Background

Cutaneous manifestations of purpura fulminans (PF) present many challenges for clinicians and surgeons. In a state of septic shock complicated by limb ischemia, surgical interventions are necessary to control the pathological cascade and improve patient outcomes. The objective of this article was to report etiologies and surgical outcomes associated with cutaneous manifestations in adults.

Methods

This systematic review and meta-analysis compared 190 adult patients with etiologies, signs and symptoms, and surgical outcomes associated with cutaneous manifestations of PF. The PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases were systematically and independently searched. Patient and clinical characteristics, surgical interventions, outcomes, and complications were recorded.

Results

Seventy-nine studies were eligible for the systematic review, and 77 were eligible for meta-analysis using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) and Cochrane guidelines. A total of 71/190 (38%) cases reported surgical debridement. Fasciotomies were reported in 12/190 (6%) cases and 20 procedures. Amputations were reported in 154/190 (81%) cases. Reconstruction was reported in 45 cases. Skin grafts were applied in 31 cases. Flaps were used for reconstruction in 28 cases. Median (IQR) surgical procedures per patient were 4 (4, 5) procedures. Infectious organisms causing PF were 32% Neisseria meningitidis (n = 55) and 32% Streptococcus pneumonia (n = 55). Coagulase-negative Staphylococcus (95% confidence interval (CI)(8.2-177.9), p = 0.032), Haemophilus influenza (95%CI (7.2-133), p = 0.029), Streptococcus pneumonia (95% CI (13.3-75.9), p = 0.006), and West Nile Virus (95%CI (8.2-177.9), p = 0.032) were associated with significantly more extensive amputations compared to other organisms.

Conclusion

This systematic review and patient-level meta-analysis found the most common presentation of PF was septic shock from an infectious organism. Neisseria meningitidis and Streptococcus pneumonia were equally the most common organisms associated with PF. The majority of cases were not treated in a burn center. The most common surgeries were amputations, with below-the-knee-amputations being the most common procedure. Skin grafting was the most commonly performed reconstructive procedure. The most common complications were secondary infections. Organisms with significantly more extensive amputations were coagulase-negative Staphylococcus, Haemophilus influenza, Streptococcus pneumonia, and West Nile Virus. Interpretation of findings should be cautioned due to limited sample data.

Genotypic and phenotypic character of Chinese neonates with congenital protein C deficiency: a case report and literature review

Background

Our objective was to study the phenotype of and molecular genetic mechanisms underlying congenital protein C (PC) deficiency in Chinese neonates. We report the case of a neonate who presented 4 h after birth with purpura fulminans of the skin and thrombosis in the kidney. We also carried out a through literature review to study the genotype and phenotype, relevance, diagnosis, management, and prognosis of neonates with congenital PC deficiency in China.

Case presentation and literature review

Following a septic work-up and check of PC and protein S (PS) levels that showed PC deficiency, we investigated the patient’s and her parents’ genotypes. Our patient was found to have a plasma PC level of 0.8%. Molecular testing revealed a compound heterozygous mutation of the PROC gene: From the father, a c._262 G > T p. ASP88Tyr mutation in exon 4; from the mother, a C. 400 + 5G mutation in intron 5 that had been previously reported as likely pathogenic. Both parents were found to have heterozygous mutations for PC deficiency. In China, 5 other cases of congenital PC deficiency in the neonatal period were reported in the literature. In those cases, purpura fulminans and thrombosis were the main symptoms, and homozygous or compound heterozygous mutations of the PROC gene were identified.

Conclusion

Congenital PC deficiency should be ruled out for neonates presenting with purpura fulminans and thrombosis.

Purpura fulminans manifesting with Staphylococcus aureus endocarditis: a case report

BACKGROUND

Purpura fulminans (PF) is a haematologic emergency that can occur in the setting of severe septic shock. Its pathophysiology is not well-understood; however, some evidence suggests it may be mediated by excessive protein C consumption.

CASE SUMMARY

In this case report, we describe a patient with PF secondary to methicillin-resistant Staphylococcus aureus endocarditis. She presented with severe septic shock and, despite haemodynamic improvement, developed a significant purpuric rash. Diagnostic work-up was notable for severely decreased serum levels of protein C. This patient was successfully treated with protein C concentrate and surgical valve replacement.

DISCUSSION

While PF is rarely associated with S. aureus infection, this presentation may be more frequently encountered among clinicians in the current opioid epidemic. Quick recognition is crucial and a multidisciplinary approach, including intravenous infusion of protein C, may be considered.

Meningococcal purpura fulminans and severe myocarditis with clinical meningitis but no meningeal inflammation: a case report

Background

During fulminant meningococcal septicaemia, meningococci are often observed in the cerebrospinal fluid (CSF) although the patients have frequently no meningeal symptoms. Meningococcal meningitis, by contrast, usually features clinical meningeal signs and biochemical markers of inflammation with elevated white blood cell count (pleiocytosis) in the CSF. Cases of typical symptomatic meningitis without these biochemical features are uncommon in adults.

Case presentation

A 21-year-old male presented with meningococcal purpura fulminans and disseminated intravascular coagulation (DIC) associated with multiple organ dysfunction syndrome requiring hospitalization in the Intensive Care Unit. Despite typical meningeal clinical signs, lumbar puncture showed no pleiocytosis, normal glycorachia and normal proteinorachia, whereas the lactate concentration in the CSF was high (5.8 mmol/L). CSF culture showed a high inoculum of serogroup C meningococci. On day 2, after initial improvement, a recurrence of hypotension led to the diagnosis of acute meningococcal myocarditis, which evolved favourably within a week. During the hospitalization, distal ischemic and necrotic lesions were observed, predominantly on the fingertips, which were treated with local and systemic vasodilators.

Conclusions

We report a rare case of adult meningococcal disease characterized by an intermediate form of meningitis between purulent meningitis and meningeal inoculation from fulminant meningococcal septicaemia, without classical signs of biological inflammation. It highlights the diagnostic value of CSF lactate, which may warrant administration of a meningeal dosing regimen of beta-lactam antibiotics. This case also demonstrates the potential severity of meningococcal myocarditis; we discuss its pathophysiology, which is distinct from other sepsis-related cardiomyopathies. Finally, the observed effects of vasodilators on the meningococcal skin ischemia in this case encourages future studies to assess their efficacy in DIC-associated necrosis.

[Purpura fulminans related to paroxysmal nocturnal haemoglobinuria: a case report and literatures review]

Objective: To improve the understanding of the rare clinical presentation and management of purpura fulminans (PF) in patients with paroxysmal nocturnal haemoglobinuria (PNH). Methods: A case of PF occurring in PNH is reported, while the related literature review is conducted. Results: A 49-year-old male patient suffered from one-week history of fever, greenish-brown colour urine, multiple well demarcated and painful purpura of the head and neck. He had been reported to have two thromboembolic events during the 22-year course of PNH. Skin biopsy displayed classic PF features. Laboratory testing showed a high PNH clone, intravascular hemolysis and coagulation system changes. After sufficient anticoagulation and short course of glucocorticoid therapy, the clinical conditions were improved correspondingly. During a follow-up period of 6 month, there was no recurrence of thrombosis. Conclusion: PF should be considered in PNH patients with unexplained, quickly developed painful purpura. Extensive work-up should be performed to find out other potential thrombophilic risk factors after diagnosis of PF. Early diagnosis, adequate anticoagulation therapy and control hemolysis were essential to PF treatment occurring in PNH. The survival of patients and the qualities of life can be improved. The PNH clone detection is needed to evaluate the status of procoagulation and predict the risk of recurrent thrombosis.

Purpura fulminans with Lemierre's syndrome caused by Gemella bergeri and Eikenella corrodens: a case report

BACKGROUND

Gemella bergeri is one of the nine species of the genus Gemella and is relatively difficult to identify. We herein describe the first case of septic shock due to a Gemella bergeri coinfection with Eikenella corrodens.

CASE PRESENTATION

A 44-year-old Asian man with a medical history of IgG4-related ophthalmic disease who was prescribed corticosteroids (prednisolone) presented to our hospital with dyspnea. On arrival, he was in shock, and a purpuric eruption was noted on both legs. Contrast enhanced computed tomography showed fluid retention at the right maxillary sinus, left lung ground glass opacity, and bilateral lung irregular opacities without cavitation. Owing to suspected septic shock, fluid resuscitation and a high dose of vasopressors were started. In addition, meropenem, clindamycin, and vancomycin were administered. Repeat computed tomography confirmed left internal jugular and vertebral vein thrombosis. Following this, the patient was diagnosed with Lemierre's syndrome. Furthermore, he went into shock again on day 6 of hospitalization. Additional soft tissue infections were suspected; therefore, bilateral below the knee amputations were performed for source control. Cultures of the exudates from skin lesions and histopathological samples did not identify any pathogens, and histopathological findings showed arterial thrombosis; therefore it was concluded that the second time shock was associated with purpura fulminans. Following this, his general status improved. He was transferred to another hospital for rehabilitation. The blood culture isolates were identified as Gemella bergeri and Eikenella corrodens. Gemella bergeri was identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry and confirmed by 16S rRNA gene sequencing later. The primary focus of the infection was thought to be in the right maxillary sinus, because the resolution of the fluid retention was confirmed by repeat computed tomography.

CONCLUSIONS

Gemella bergeri can be the causative pathogen of septic shock. If this pathogen cannot be identified manually or through commercial phenotypic methods, 16S rRNA gene sequencing should be considered.

Clinical spectrum and short-term outcome of adult patients with purpura fulminans: a French multicenter retrospective cohort study

PURPOSE

Data on purpura fulminans (PF) in adult patients are scarce and mainly limited to meningococcal infections. Our aim has been to report the clinical features and outcomes of adult patients admitted in the intensive care unit (ICU) for an infectious PF, as well as the predictive factors for limb amputation and mortality.

METHODS

A 17-year national multicenter retrospective cohort study in 55 ICUs in France from 2000 to 2016, including adult patients admitted for an infectious PF defined by a sudden and extensive purpura, together with the need for vasopressor support. Primary outcome variables included hospital mortality and amputation during the follow-up period (time between ICU admission and amputation, death or end of follow-up).

RESULTS

Among the 306 included patients, 126 (41.2%; 95% CI 35.6-46.9) died and 180 (58.8%; 95% CI 53.3-64.3) survived during the follow-up period [13 (3-24) days], including 51/180 patients (28.3%, 95% CI 21.9-35.5) who eventually required limb amputations, with a median number of 3 (1-4) limbs amputated. The two predominantly identified microorganisms were Neisseria meningitidis (63.7%) and Streptococcus pneumoniae (21.9%). By multivariable Cox model, SAPS II [hazard-ratio (HR) = 1.03 (1.02-1.04); p < 0.001], lower leucocytes [HR 0.83 (0.69-0.99); p = 0.034] and platelet counts [HR 0.77 (0.60-0.91); p = 0.007], and arterial blood lactate levels [HR 2.71 (1.68-4.38); p < 0.001] were independently associated with hospital death, while a neck stiffness [HR 0.51 (0.28-0.92); p = 0.026] was a protective factor. Infection with Streptococcus pneumoniae [sub-hazard ratio 1.89 (1.06-3.38); p = 0.032], together with arterial lactate levels and ICU admission temperature, was independently associated with amputation by a competing risks analysis.

CONCLUSION

Purpura fulminans carries a high mortality and morbidity. Pneumococcal PF leads to a higher risk of amputation.

Sloughing skin in intravenous drug user

A 32 year old female, an active intravenous drug user, was admitted for fever, myalgias and an erythematous macular rash on her distal extremities. She quickly decompensated and developed septic shock. Her examination was significant for a progressive rash which within two days developed bullae and necrosis with progression to a confluent rash involving her palms and soles (Figs. 1 and 2). Her rash involved nearly one third of her body with what was equivalent to a third degree burn. Her labs were significant for leukocytosis with bandemia, elevated liver function tests with worsening thrombocytopenia and fibrinogen levels consistent with disseminated intravascular coagulation (DIC) Her transthoracic echocardiogram (Fig. 3) showed a 5 cm vegetation on the tricuspid valve. Her blood cultures were positive for methicillin-sensitive Staphylococcus aureus. She was meeting the clinical criteria for toxic shock syndrome (TSS) and subsequent testing for toxic shock syndrome toxin antibody was positive. She was treated with antibiotics and intravenous gamma globulin (IVIG). Due to her worsening rash she was transferred to a burns unit. She was diagnosed with Purpura fulminans (PF) which is a skin manifestation of DIC and has a rare association with Staphylococcus aureus infection.The main focus of this case report is to emphasise this rare association, prompt an early diagnosis and referral to prevent life threatening complications.

Rare presentation of rickettsial infection as purpura fulminans: a case report

BACKGROUND

Purpura fulminans is an acute life-threatening disorder characterized by intravascular thrombosis and hemorrhagic infarction of the skin complicated with disseminated intravascular coagulation. It is commonly seen in acute infections following meningococcal and streptococcal infections. Few cases of purpura fulminans following rickettsial infections have been described in the literature.

CASE PRESENTATION

We report a case of a 55-year-old Sri Lankan woman who presented to Teaching Hospital Peradeniya with a febrile illness, headache, and myalgia that progressed to an erythematous rash starting over the bilateral lover limbs and hands and that became black and necrotic with a few hemorrhagic blebs. She had normocytic anemia, platelet clumps, and monocytosis as well as a deranged clotting profile. The result of immunofluorescence antibody testing for rickettsial immunoglobulin G was strongly positive for Rickettsia conorii with a rise in titer convalescent sera, and a diagnosis of purpura fulminans following rickettsial infection was made. The patient made an excellent recovery with chloramphenicol treatment.

CONCLUSIONS

The treating physician should consider the rare but very treatable condition of rickettsial infection as a differential diagnosis in the etiological diagnostic workup of patients presenting with severe purpuric and hemorrhagic rash with fever.

Establishing the critical role of peripheral blood vessel colonisation by Neisseria meningitidis in invasive meningococcal disease

In this issue of Virulence, Capel and colleagues describe the use of a unique humanised mouse model to elucidate specific interactions between Neisseria meningitidis and human endothelial cells during blood-borne infection in vivo. Here, a number of the key findings from their study and their implications for our understanding of invasive meningococcal disease are explored.

Purpura Fulminans: Mechanism and Management of Dysregulated Hemostasis

Purpura fulminans (PF) is a highly thrombotic subtype of disseminated intravascular coagulation that can accompany severe bacterial, and more rarely, viral infections. PF is associated with an extremely high mortality rate, and patients often die of overwhelming multisystemic thrombosis rather than septic shock. Survivors typically experience amputation of involved extremities and significant scarring in affected areas. Despite the devastating clinical course associated with this hemostatic complication of infection, the mechanism of PF remains poorly understood. Severe acquired deficiency of protein C and dysfunction of the protein C-thrombomodulin pathway as well as other systems that exert a negative regulatory effect on coagulation have been implicated. Management of PF involves treatment of the underlying infection, aggressive anticoagulation, and robust transfusion support aimed at correcting acquired deficiencies in natural anticoagulant proteins. In this review, we address the diagnosis and management of PF with a focus on a rational approach to this condition informed by the available data. Proposed mechanisms underlying the dysregulation of coagulation seen in PF are also covered, and implications for therapy are discussed.

Atypical Presentation Of Rickettsial Spotted Fever

Acute febrile illness is a common entity in tropics and often is challenging due a host of pathogenic bacteria, viruses and fungi. Extensive work up is required for better management. Rickettsiosis is uncommon and hence comes lower down in the differentials of multiorgan failure being superseded by the more common diseases as malaria, enteric fever and Dengue. We document a case of young male presenting with high grade fever, multiorgan dysfunction (hepatic, renal, neurological and respiratory involvement), conjunctival suffusion, retiform rash and without lymphadenopathy. The diagnosis was further challenging because the rashes appeared late at 8th day in the course of illness, unlike the typical disease where rashes come on early in day 3-6 of the disease. Patient responded to timely treatment with doxycycline. Thus, a high index of suspicion is needed to diagnose Rickettsiosis in geographical areas apparently free of the disease.

Widespread subcutaneous necrosis in spotted fever group Rickettsioses from the coastal belt of Sri Lanka- a case report

BACKGROUND

Spotted fever group rickettsioses (SFGR) transmitted mostly by ticks are increasingly discovered around the World and some of them are either re-emerging or emerging in Sri Lanka. Accidental human infections caused by these vector borne zoonotic diseases generally give rise to nonspecific acute febrile illnesses which can be complicated by multi organ involvement carrying high morbidity and mortality. Nonspecific clinical features and non-availability of early diagnostic facilities are known to result in delay in the diagnosis of rickettsial infections. Therefore, awareness of their prevalence and more importantly their clinical features would be help in the early diagnosis and institution of appropriate therapy.

CASE PRESENTATION

A 39-year-old otherwise healthy female presented with an acute febrile illness complicated by severe small joint and large joint arthritis, jaundice, acute kidney injury and disseminated intravascular coagulation (DIC) mimicking palindromic rheumatism or severe sepsis. She later developed a widespread fern-leaf pattern necrotic skin rash with evidence of vasculitis on the palms and soles, aiding the clinical diagnosis of SFGR. She had very high antibody titres against R. conorii antigen confirming the diagnosis and recovered completely with anti-rickettsial therapy.

CONCLUSION

We feel that clinicians should be aware of the unusual clinical presentations such as purpura fulminans and 'fern-leaf' pattern necrotic skin rash of SFGR infection. Such knowledge would not only benefit those who practice in tropics with limited diagnostic facilities but also would improve the management of acute febrile illness in returning travelers who visit endemic areas.

[Management of purpura fulminans lesions in children]

Purpura fulminans is a pediatric life-threatening emergency with a significant mortality, combining: septic shock, extensive purpuric lesions and disseminated intravascular coagulation. The most frequent bacterial pathogen is the meningococcus. The medical management includes antibiotics, corticoids, vascular filling and catecholamines. Purpura fulminans is characterized by the extent of hemorrhagic and mainly thrombotic lesions, attributed to the alteration in the vascular endothelium functions. Damage of soft tissues combines large necrotic areas and more or less extensive distal ischemic lesions. Necrotic lesions can be deep, reaching skin, subcutaneous tissue, fascia, muscle and sometimes even the bone. The importance of the aesthetic and functional sequelae as well as future quality of life, depend on the quality of surgical management for these wide and deep lesions. Fasciotomy is sometimes urgently needed in the case of a clinical compartment syndrome, confirmed by a high-pressure measurement in the muscle compartments. Debridement of necrotic lesions and amputations are only performed after a clear delineation of necrotic areas, between 10 days and 3 weeks of evolution. If an amputation is necessary, it must focus on the residual bone length, considering the child's growth potential. The coverage of tissue loss uses all the plastic surgery techniques, more or less complex, in order to reduce scars to minimum for these children. Rehabilitation follow-up includes physical and psychological care, which are essential until adulthood.

Fatal purpura fulminans and Waterhouse-Friderichsen syndrome from fulminant Streptococcus pneumoniae sepsis in an asplenic young adult

Asplenic patients are at increased risk for sepsis and fulminant infection. Sepsis in these patients is typically secondary to encapsulated bacteria, with Streptococcus pneumoniae being the most frequent pathogen. Rare complications of severe sepsis include purpura fulminans and bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome). We present the case of a 36-year-old woman, healthy except for splenectomy years prior for idiopathic thrombocytopenic purpura treatment, who presented with fever. Upon presentation to our hospital, three hours after symptoms onset, she had purpura fulminans and shock. Despite timely antimicrobials and maximal resuscitative efforts, her disease progressed and she expired 12 hours after symptoms onset. Autopsy revealed bilateral adrenal hemorrhage; acute adrenal crisis likely contributed to her refractory shock. Prior to her presentation, she had not received guideline-based post-splenectomy care. Sepsis in asplenic patients can be fulminant and rapidly fatal. Streptococcus pneumoniae remains the most frequent cause, despite decreasing rates in recent years related to widespread pneumococcal vaccination. Guideline-based vaccinations and "pill-in-pocket" therapy can be life-saving for asplenic patients. Purpura fulminans represents an extreme manifestation of disseminated intravascular coagulation, is more common in asplenic patients, and portends a poor prognosis. Waterhouse-Friderichsen syndrome can be seen concurrently with purpura fulminans and further portends a poor prognosis; pre-mortem diagnosis requires a high index of suspicion.

Loss of orofacial tissue secondary to septic shock caused by Streptococcus pneumoniae

Purpura fulminans is a rare complication of septic shock with a high mortality. It can result in a severe loss of skin, and often amputation of limbs. Managing the loss of tissue is a challenge that requires a multidisciplinary approach.

Purpura fulminans secondary to rickettsial infections: A case series

Purpura fulminans (PF) is a descriptive term used to describe a heterogeneous group of disorders characterized by rapidly progressive purpuric lesions that may develop into extensive areas of skin necrosis, and peripheral gangrene. This rare disorder is associated with laboratory evidence of consumptive coagulopathy and is often fatal. PF is usually associated with many infections, most notably with meningococcal, staphylococcal, and streptococcal infections. However, there are very few reports of this entity with spotted fever and scrub typhus from India. Rickettsial infections are an underdiagnosed group of diseases presenting as acute febrile illness, with high mortality in untreated cases. Of the available tests, Weil–Felix is a handy and economical tool for early diagnosis of this fatal disease especially in resource poor settings. We present four infants with PF secondary to rickettsial fever diagnosed by the Weil–Felix test.
