RESUMO

BACKGROUND AND OBJECTIVES: Deficiencies of protein C (PC) or protein S (PS) are rare diseases, characterized by mutations in the PC or PS genes, which encode plasma serine proteases with anti-coagulant activity. Severe PC or PS deficiencies manifest in early life as neonatal purpura fulminans, a life-threatening heamorrhagic condition requiring immediate treatment. First-line treatment involves replacement therapy, followed by maintenance with anti-coagulants. Replacement therapy with specific protein concentrates is currently only limited to PC, and therefore, a PC + PS concentrate represents a useful addition to therapeutic options, particularly for severe PS deficiency. Further, the production of a PC + PS concentrate from unused plasma fractionation intermediates would impact favourably on manufacturing costs, and consequently therapy prices for patients and health systems. MATERIALS AND METHODS: Several chromatographic runs were performed on the same unused plasma fractionation intermediates using different supports to obtain a PC/PS concentrate. The best chromatographic mediums were chosen, in terms of specific activity and recovery. A full process of purification including virus inactivation/removal and lyophilization steps was set up. RESULTS: The final freeze-dried product had a mean PC concentration of 47.75 IU/mL with 11% of PS, and a mean specific activity of 202.5 IU/mg protein, corresponding to over 12,000-fold purification from plasma. CONCLUSION: The development of a novel concentrated PC/PS mixture obtained from a waste fraction of other commercial products could be used for its potential therapeutic role in the management of neonatal purpura fulminans pathology.

RESUMO

The patient was a man in his 80s who had undergone laparoscopic anterior resection for rectal cancer. Bowel obstruction occurred on the third postoperative day but improved with a decompression tube by the fifth postoperative day. A high fever (in the 38 °C range) was also observed. Blood culture tests detected two sets of the gram-negative bacilli Klebsiella aerogenes within 24 h of collection. On the seventh postoperative day, the patient subsequently went into septic shock with disseminated intravascular coagulation (DIC). On the eighth postoperative day, the fingertips and toes became black, and the palms and dorsal surfaces of both feet were dark purple due to peripheral circulatory failure. This suggested acute infectious purpura associated with sepsis (acute infectious purpura fulminans (AIPF)). Intensive care was provided; however, the necrosis of both middle fingers worsened, both middle fingers were gangrenous, and the patient died on the thirtieth postoperative day. AIPF is rarely reported, especially in early-onset cases after elective surgery. We encountered a rare complication of bacterial translocation from postoperative bowel obstruction, leading to AIPF.

RESUMO

BACKGROUND: Neisseria meningitidis is the leading responsible bacterium of Purpura Fulminans (PF) accounting for two thirds of PF. Skin biopsy is a simple and minimally invasive exam allowing to perform skin culture and polymerase chain reaction (PCR) to detect Neisseria meningitidis. We aimed to assess the sensitivity of skin biopsy in adult patients with meningococcal PF. METHODS: A 17-year multicenter retrospective cohort study including adult patients admitted to the ICU for a meningococcal PF in whom a skin biopsy with conventional and/or meningococcal PCR was performed. RESULTS: Among 306 patients admitted for PF, 195 had a meningococcal PF (64%) with a skin biopsy being performed in 68 (35%) of them. Skin biopsy was performed in median 1 day after the initiation of antibiotic therapy. Standard culture of skin biopsy was performed in 61/68 (90%) patients and grew Neisseria meningitidis in 28 (46%) of them. Neisseria meningitidis PCR on skin biopsy was performed in 51/68 (75%) patients and was positive in 50 (98%) of them. Among these 50 positive meningococcal PCR, five were performed 3 days or more after initiation of antibiotic therapy. Finally, skin biopsy was considered as contributive in 60/68 (88%) patients. Identification of the meningococcal serogroup was obtained with skin biopsy in 48/68 (71%) patients. CONCLUSIONS: Skin biopsy with conventional culture and meningococcal PCR has a global sensitivity of 88% and should be systematically considered in case of suspected meningococcal PF even after the initiation of antimicrobial treatment.

RESUMO

Cutaneous manifestations developed in the course of sepsis are poorly documented in the medical literature beyond those related to specific pathogens or classical clinical pictures such as purpura fulminans or ecthyma gangrenosum. The objective of this study was to determine the overall prevalence of sepsis-related skin findings and evaluate their possible impact on the prognosis of septic patients. Single-centre, retrospective study of septic patients with documented bloodstream infections admitted in a tertiary hospital during 2019. Primary skin and soft tissue infections, and non-sepsis-related skin conditions diagnosed during hospital admission were excluded. Unselected sample of 320 episodes of sepsis in 265 patients. Secondary skin lesions were documented in 57 sepsis episodes (17.8%) in 47 patients. Purpura (petechiae/ecchymosis) was the most frequent cutaneous finding in septic patients (35.5%), with non-acral involvement in more than one-third of the episodes (38.5%), followed by skin and soft tissue erythema/oedema (25.8%) and maculopapular rashes (11.3%). Secondary skin lesions occurred more frequently in sepsis of respiratory (p = 0.027) and skin and soft tissue (p = 0.018) origin, as well as in sepsis caused by Pseudomonas aeruginosa and Stenotrophomonas maltophilia (p = 0.001). Mean hospital stay was 38.58 days and sepsis-related mortality 21.1%. Our results suggest that cutaneous involvement in the course of sepsis is frequent, with purpura being the main clinical sign. The semiology described in this study, easily identifiable by non-dermatologists, should alert clinicians to the potential unfavourable course of these patients.

RESUMO

OBJECTIVE: To clarify the incidence and genetic risk of neonatal-thromboembolism, we conducted a nationwide study exploring the impact of thrombophilia on neonatal-thromboembolism in Japan. STUDY DESIGN: A questionnaire survey was conducted for perinatal centers in Japan, focusing on the clinical expression, genotype, treatment, and outcome of patients who developed thromboembolism within 28 days of birth from 2014 to 2018. RESULTS: The estimated incidence of neonatal-thromboembolism was 0.39 cases per 10 000 live births. Intracranial lesions and purpura fulminans occurred in 66 and 5 of 77 patients, respectively. Fifty-eight (75.3%) infants presented within 3 days after birth. Four (5.2%) died, and 14 (18.2%) survived with disability. At the diagnosis, <20% plasma activity of protein C was noted in 16 infants, protein S (in 2), and antithrombin (in 1). Thirteen genetic tests identified 4 biallelic and 5 monoallelic protein C-variants but no protein S- or antithrombin-variants. Protein C-variants had purpura fulminans (P < .01), ocular bleeding (P < .01), positive-family history (P = .01), and death or disability (P = .03) more frequently than others. Protein C-variants were independently associated with disability (OR 5.74, 95% CI 1.16-28.4, P = .03) but not death. Four biallelic variants had serious thrombotic complications of neurologic disability, blindness, and/or amputation. Three monoallelic variants survived without complications. The only protein C-variant death was an extremely preterm heterozygote infant. CONCLUSIONS: Monoallelic protein C-variants had a higher incidence of neonatal-thromboembolism than biallelic variants. Thrombophilia genetic testing should be performed in the setting of neonatal-thromboembolism and low protein C to identify the underlying genetic defect.

RESUMO

In patients who develop sepsis, whether due to primary, secondary or metastatic lesions, the skin is frequently affected. However, there are unresolved aspects regarding the general clinical manifestations in the skin or the prognosis and/or therapeutic implications. The main challenge in the approach to sepsis is its early diagnosis and management. In this review, we address the sepsis-skin relationship and the potential impact of early dermatological intervention on the septic patient through ten basic questions. We found little evidence of the participation of the dermatologist in sepsis alert programs. There are early skin changes that may alert clinicians on a possible sepsis, such as skin mottling or variations in acral skin temperature. In addition, the skin is an accessible and highly cost-effective tissue for etiological studies of some forms of sepsis (e.g., meningococcal purpura) and its involvement defines the prognosis of certain patients (e.g., infective endocarditis).

RESUMO

Severe protein C deficiency due to biallelic PROC mutations is an extremely rare thrombophilia, most commonly presenting during the neonatal period as purpura fulminans. Despite treatment, severe morbidity and mortality are frequent. The current study reports 3 unrelated patients harboring novel homozygous PROC mutations and their clinical phenotypes. We discuss how the cytoprotective activity of protein C and its role in the stabilization of endothelial barriers may account for the unique symptoms of this thrombophilia.

RESUMO

Purpura fulminans (PF) is a syndrome characterized by the sudden onset of progressive skin hemorrhage, necrosis of the extremities, and thrombotic occlusion. Although the cause is believed to be protein C deficiency, many aspects of this syndrome have yet to be clarified. A 45-year-old Japanese woman, G2P2 (vaginal delivery), developed fever and lower abdominal pain. It was her 5th day of menstruation, and a tampon had been in the vagina for a few days. Septic shock and disseminated intravascular coagulation were diagnosed, and multidisciplinary treatment was started. Also, toxic shock syndrome due to tampon use was suspected. The purpura on the limbs turned into blisters and then blackish-purple spots, leading to hemorrhagic necrosis within a few days. Moreover, imaging showed that the uterus and both adnexa had enlarged significantly, and raised suspicion of abscess formation. Total hysterectomy and bilateral adnexectomy were performed, and the histopathological diagnosis was hemorrhagic necrosis due to extensive thrombus formation. In men, PF affects the scrotum and penis, leading to autoamputation of the male genitalia, while there are no reports of PF involving the female genitalia. Regarding the PF, in this case, we considered the possibility of pathologic conditions progressing to the female genitalia.

RESUMO

BACKGROUND: Infectious purpura fulminans is a disabling disease often leading to amputations. Free flaps preserve limb length, covering exposed areas. We examined the efficacy of free flaps for lower limb salvage in infectious purpura fulminans survivors by evaluating surgical management, walking ability and quality of life. METHODS: This single-center, observational, descriptive, retrospective study was conducted in from 2016 to 2019. Adult purpura fulminans survivors who received a free flap for lower limb salvage were included. Patient characteristics and data on surgical management and rehabilitation were collected. Quality of life (SF-36 questionnaire), limb function and walking ability were later evaluated post-surgically. RESULTS: The 6 patients included, mean age 38 years, had all required amputations. Nine free flaps were performed to cover important structures in 7 cases and for stump resurfacing in 2. All flaps were successful. Patients resumed walking at a mean of 204±108 days after the onset of purpura fulminans. Post-surgical evaluation was performed at a mean of 30±9.3 months. Five patients required secondary revision. All were independent for the activities of daily living. Mean physical component score was 37.6±9.4 and mental component score was 44.6±13.2 (minimum 0, maximum 100). CONCLUSIONS: Use of the free flap in patients with infectious purpura fulminans, after multidisciplinary reflection, is an appropriate procedure that preserves limb length. In spite of secondary complications, preservation of limb length enables patients to resume walking, with relatively good independence and quality of life.

RESUMO

BACKGROUND: Pneumococcal infections remain the main cause of overwhelming post-splenectomy infections, and purpura fulminans may develop in almost 20% of patients with overwhelming post-splenectomy infection. We aimed at describing the impact of asplenia/hyposplenia on the clinical features and the outcomes of adult patients admitted to the intensive care unit (ICU) for pneumococcal purpura fulminans. METHODS: A 17-year national multicenter retrospective cohort study included adult patients admitted to 55 French ICUs for an infectious purpura fulminans from 2000 to 2016. Patients with pneumococcal purpura fulminans were analyzed according to the absence or presence of asplenia/hyposplenia. RESULTS: Among the 306 patients admitted to the ICU for purpura fulminans, 67 (22%) had a pneumococcal purpura fulminans, of whom 34 (51%) had asplenia (n = 29/34, 85%) or hyposplenia (n = 5/34, 15%) and 33 (49%) had eusplenia. The prevalence of pneumococcal purpura fulminans was seven times higher in asplenic/hyposplenic patients compared to eusplenic patients with purpura fulminans (n = 34/39, 87% vs. n = 33/267, 12%; p < 0.001). The median time interval between the occurrence of asplenia/hyposplenia and ICU admission was 20 [9-32] years. Pneumococcal vaccine coverage was 35% in asplenic/hyposplenic patients. Purpura was more frequently reported before ICU admission in asplenic/hyposplenic patients (n = 25/34, 73% vs. n = 13/33, 39%; p = 0.01). The rate of bacteremia did not differ between asplenic/hyposplenic and eusplenic patients (n = 31/34, 91% vs n = 27/33, 82%; p = 0.261). SAPS II (60 ± 14 vs. 60 ± 18; p = 0.244) and SOFA (13 [1-5] vs. 14 [1-4, 6]; p = 0.48) scores did not differ between asplenic/hyposplenic and eusplenic patients. There were no significant differences between asplenic/hyposplenic and eusplenic patients regarding the rate of limb amputation (n = 9/34, 26% vs. 15/33, 45%; p = 0.11) and hospital mortality (n = 20/34, 59% vs. n = 15/33, 45%; p = 0.27). CONCLUSIONS: Half of pneumococcal purpura fulminans episodes occurred in asplenic or hyposplenic patients. Pneumococcal vaccine coverage was reported in one third of asplenic/hyposplenic patients. Half of pneumococcal purpura fulminans episodes occurred more than 20 years after splenectomy. Outcomes of pneumococcal purpura fulminans did not show significant differences between patients with or without asplenia or hyposplenia, although the small number of patients included limited our power to detect potential differences between groups.

RESUMO

BACKGROUND: Purpura fulminans, an uncommon syndrome of intravascular thrombosis with hemorrhagic infarction of the skin, is often accompanied by disseminated intravascular coagulation (DIC) and multi-organ failure, and may ultimately lead to death. METHODS: Herein, we document 13 skin biopsies from 11 adult patients with the clinical diagnosis of sepsis and confirmed histopathologic diagnosis of intravascular thrombosis and/or DIC, compatible with acute infectious purpura fulminans (AIPF). Detailed history and clinical examination were performed, and the lesions were correlated with histopathologic findings. Any underlying medical disease was taken into consideration. RESULTS: There were 5 males and 6 females with lower extremity or peri-incisional purpuric skin lesions. The most important comorbidities identified were a history of surgical procedure or neoplasm, although 4 patients had no relevant underlying history. Most skin biopsies revealed focal epidermal ischemia or necrosis and 3 showed full-thickness epidermal necrosis. In the underlying dermis, there were fibrin thrombi in superficial and deep blood vessels with acute inflammation. Changes of an inflammatory destructive vasculitis were identified in 5 cases. No bacteria or fungi were identified on histopathology. CONCLUSIONS: AIPF is a rapidly-progressing medical emergency which may be identified by histopathology in culture-negative cases. Biopsies may show neutrophilic infiltrate without infective organisms.

RESUMO

Disseminated intravascular coagulation (DIC) is linked with severe COVID-19, prompting considerable concern. DIC can be a devastating systemic disorder. It is often markedly manifest on the skin as acrocyanosis or as petechiae and purpura with progression to hemorrhagic bullae. Subcutaneous hematomas may occur, as may thrombotic findings including necrosis and gangrene. The most common cause is infection, with special emphasis now on COVID-19. We have reviewed the medical literature under the search terms "Disseminated intravascular coagulation" and "consumption coagulopathy" for the past two decades in the English language using Medline and Google Scholar to update special concerns and considerations, focusing on those with COVID-19. Skin findings with DIC may be prominent. The severity of cutaneous lesions often correlates with the gravity of systemic disease. DIC is most effectively treated by addressing the underlying cause and resuscitating the patient using supportive measures. It is pivotal to recognize and treat DIC early, before deadly complications, such as multiple organ failure, arise.

RESUMO

Capnocytophaga canimorsus, commonly transmitted by dog bites, can cause severe sepsis, and the mortality rate is very high. We experienced a case of hemophagocytic lymphohistiocytosis (HLH) complicated by severe sepsis caused by C. canimorsus. A 58-year-old man with no remarkable medical history was admitted to another hospital with fever and mild consciousness disorder developed 3 days after being bitten by his dog. The next day, the patient developed disseminated intravascular coagulation and shock and was transferred to our emergency medical center. Blood tests showed hyperferritinemia and cytopenia, and bone marrow aspiration was performed. As a result, we diagnosed severe sepsis and HLH. Once antibiotic and steroid therapy was started, the patient's infection and cytopenia improved. Unfortunately, the patient's fingers and toes required amputation, but his life was saved, and he was discharged from hospital. Because HLH may be hidden in such cases, it may be necessary to measure serum ferritin and perform bone marrow aspiration if hyperferritinemia is suspected.

RESUMO

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.

RESUMO

BACKGROUND: Long-term health-related quality of life (HR-QOL) of patients surviving the acute phase of purpura fulminans (PF) has not been evaluated. METHODS: This was a French multicenter exposed-unexposed cohort study enrolling patients admitted in 55 intensive care units (ICUs) for PF from 2010 to 2016. Adult patients surviving the acute phase of PF (exposed group) were matched 1:1 for age, sex, and Simplified Acute Physiology Score II with septic shock survivors (unexposed group). HR-QOL was assessed during a phone interview using the 36-Item Short-Form Health Survey (SF-36) questionnaire, the Hospital Anxiety and Depression (HAD) scale, the Impact of Event Scale-Revised (IES-R), and the activity of daily living (ADL) and instrumental ADL (IADL) scales. The primary outcome measure was the physical component summary (PCS) of the SF-36 questionnaire. RESULTS: Thirty-seven survivors of PF and 37 of septic shock were phone-interviewed at 55 (interquartile range [IQR], 35-83) months and 44 (IQR, 35-72) months, respectively, of ICU discharge (P = .23). The PCS of the SF-36 was not significantly different between exposed and unexposed patients (median, 47 [IQR, 36-53] vs 54 [IQR, 36-57]; P = .18). There was also no significant difference between groups regarding the mental component summary of the SF-36, and the HAD, IES-R, ADL and IADL scales. Among the 37 exposed patients, those who required limb amputation (n = 12/37 [32%]) exhibited lower PCS (34 [IQR, 24-38] vs 52 [IQR, 42-56]; P = .001) and IADL scores (7 [IQR, 4-8] vs 8 [IQR, 7-8]; P = .021) compared with nonamputated patients. CONCLUSIONS: Long-term HR-QOL does not differ between patients surviving PF and those surviving septic shock unrelated to PF. Amputated patients have an impaired physical HR-QOL but a preserved mental health. CLINICAL TRIALS REGISTRATION: NCT03216577.

RESUMO

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.

RESUMO

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.

RESUMO

Purpura fulminans (PF) is a neonatal presentation of homozygous or compound heterozygous protein C (PC) deficiency; infants who are diagnosed with it are determined to have a major defect in coagulation regulation which is associated with undetectable levels of PC. We report a pedigree who suffered from the hereditary PC deficiency with compound heterozygous mutants; genetic analysis revealed compound heterozygous mutations of 262 G > T(Asp88Tyr) and 400 + 5G > A that were identified in the proband; moreover, Asp88Tyr and 400 + 5G > A were also detected in the father and the mother, respectively. A bioinformatics analysis revealed 262 G > T is probably damaging, and structural analysis indicated a possible mechanism for the functional impairment of PC in this pedigree.

RESUMO

Bacteraemias are life-threatening conditions that require rapid care and antibiotherapy. Dermatological signs might help in deciding the most relevant treatment. The aim of this study was to determine the prevalence and clinical characteristics of cutaneous manifestations in hospitalized patients with bacteraemia. A cross-sectional study was conducted over a period of 1 year. All consecutive patients with a bacteraemia (except contaminations) were included and examined by a dermatologist within 48 h after positive blood cultures. Clinical (skin manifestations, diagnosis, origin of the bacteraemia) and laboratory (bacteria) data were recorded. In total, 401 bacteraemias in 375 patients were included for the final analysis. Thirty-nine cutaneous manifestations in 34 patients were noted, corresponding to a prevalence of 9%; 69% (n = 27) were considered primary cutaneous manifestations, 18% (n = 7) as secondary ones, 10% (n = 4) as contiguous, and 3% (n = 1) as undetermined. Gram-positive cocci, specifically Staphylococcus aureus and Streptococcus species, were the most frequent bacteria (n = 27, 69%).
