RESUMO

Chromobacterium violaceum (C. violaceum) is a gram-negative bacillus that is widespread in tropical and subtropical areas. Although C. violaceum rarely infects humans, it can cause critical illness with a mortality rate above 50%. Here, we report the successful treatment of a 15-year-old male who presented with bloodstream infection of C. violaceum along with sepsis, specific skin lesions, and liver abscesses. Cardiogenic shock induced by sepsis was reversed by venoarterial extracorporeal membrane oxygenation (VA ECMO). Moreover, C. violaceum-related purpura fulminans, which is reported herein for the first time, was ameliorated after treatment. This case report demonstrates the virulence of C. violaceum with the aim of raising clinical awareness of this disease.

RESUMO

Haemophilus influenzae (Hi) is a bacterium usually found in the upper respiratory tract of humans. Though it is recognized as a naturally occurring element in the human bacterial reservoir, Hi infections have the potential to be severe and even fatal, particularly when they result in conditions such as meningitis or epiglottitis. Because of this, Hi invasive infections are considered a reportable disease in Portugal. We report a case of a 58-year-old female, chronically adrenally suppressed on long-term steroids, who developed an invasive Hi type b infection that led to purpura fulminans and multiorgan failure after an acute episode of epiglottitis. According to our review of the literature, only three previous cases of invasive Hi type b disease-causing purpura fulminans have been described.

RESUMO

Purpura fulminans (PF) is a life-threatening complication of septic shock that can occur due to disseminated infections with Streptococcus pneumoniae The spleen is an important organ in the immunisation process against encapsulated bacteria. Patients with asplenia, either functional or anatomical, are therefore at increased risk of developing serious infections and complications, such as PF, if infected with such bacteria.This case report presents a woman in her late 40s with unacknowledged functional asplenia who was admitted to the hospital with signs of an acute disseminated infection causing septic shock, signs of disseminated intravascular coagulation and infectious PF. A few days after admission, the blood cultures showed growth of S. pneumoniae With early sepsis treatment, the patient survived although with some complications. Clinical presentation, investigations, differential diagnosis, treatment and outcome are presented. Treatment and early recognition of PF are presented and discussed. Relevant recognition and preventative treatment strategies for patients with asplenia are also reviewed and discussed.This case demonstrates the importance of early recognition and treatment of PF in septic patients and the importance of preventive treatment strategies for patients with asplenia to avoid serious infections and complications.

Introduction Purpura fulminans (PF) is a serious complication of sepsis resulting from a set of alterations characterised by the development of ecchymotic haemorrhagic lesions and skin necrosis. Aim To analyse the efficacy and safety of the topical application of HOFA compound, in the cutaneous microcirculation of PF lesions in paediatric patients affected by sepsis. Material and methods A prospective quasi-experimental pre-test/post-test single-group conducted in a Paediatric Intensive Care Unit of a third level hospital was performed. Paediatric patients aged 0-18 years with sepsis were included. Somatic oximetry values were measured before and after application of HOFAs every 4hours over the first three days of the patients’ hospitalisation. Patient's socio-demographic and clinical variables and somatic oximetry by placing a sensor for measuring tissue perfusion on the area with PF were determined. Results Four patients were recruited, with a median age of 98 months. The purpuric lesions measured were mainly located on both feet and hands and, in two patients, also on the lateral malleoli and calves of both lower extremities. A total of 225 measurements were obtained, with mean pre-intervention scores of 71.17±15.65% versus 73.68±14.83% post-intervention. Statistical significance (p<0.001) was observed upon comparison of the pre- and post-intervention measurements. Conclusions Early and continued application of HOFAs in the management of sepsis-induced PF is an effective and safe practice in the cases analysed.

RESUMO

Introduction: Mucocutaneous complications or adverse events due to SARS-CoV-2 infection or vaccination have been well delineated in the literature, respectively. Most eruptions are considered mild and self-limiting; however, for the atypical cases with a tentative clinical diagnosis, performing a biopsy and histopathological assessment is pivotal to confirm the diagnosis and subsequently prescribe a more tailored treatment. Despite the diverse reporting of such incidents globally, most studies restrict the rate of biopsied cases to less than 15%. Case Presentations: This case series elucidates 20 patients referred to the tertiary dermatology clinic, including 14 COVID-19 infection-related eruptions such as lichen planus (LP), cutaneous vasculitis, pityriasis rosea (PR), discoid lupus erythematosus, guttate psoriasis, sarcoidosis, Raynaud's phenomenon, non-specific lesions resembling genital warts, Beau's line, and one severe case of purpura fulminans with a promising outcome. Moreover, we presented six vaccine-induced cases comprising LP, urticarial vasculitis, PR, parapsoriasis, and localized morphea. The diagnosis of all challenging cases has been proven by histopathological evaluation. We included pertaining anamnesis details of each patient and vivid classifying images to pinpoint the morphologic features of each condition. Discussion: In line with our previous studies, the vaccine-induced eruptions were less severe compared to infection-related complications of COVID-19 and are mostly controllable by antihistamines and corticosteroid administration. Therefore, reporting such events should not impede COVID-19 vaccination in the general population.

RESUMO

Neonatal purpura fulminans (PF) is an uncommon skin disorder characterized by acute disseminated intravascular coagulation, tissue necrosis, and small vessel thrombosis. Here, we present a case of a seven-day-old male who was admitted to the Neonatal Intensive Care (NICU) Unit at Gaafar Ibn Auf Tertiary Hospital, in January 2023. He presented with black bullous lesions on the plantar surface of the left foot, deep bluish discoloration over the right buttock and right lower abdomen, and gangrenous changes in the right foot with clear demarcation. Birth history was not significant other than mild pallor and icterus. His blood workup was consistent with severe anemia, thrombocytopenia, elevated prothrombin time, and partial thromboplastin time with decreased protein C and S levels; blood culture yielded no growth. A Doppler ultrasound scan of lower extremities confirmed distal occlusion of the right dorsalis pedis artery. The abdominal ultrasound revealed a free left renal bed and left-sided renal agenesis. We came to a diagnosis of neonatal PF and started administering blood and fresh frozen plasma and subcutaneous heparin injections, but unfortunately, the patient eventually passed away. Hence, we decided to report this case to emphasize the significance of the clinical picture in assisting with early diagnosis, despite limited access to genetic testing. We also want to highlight the importance of a "high index of suspicion" that might be mandatory for better outcomes.

RESUMO

Acquired postinfectious purpura fulminans is a rare, acute, and severe disease characterized by skin necrosis associated with disseminated intravascular coagulation (DIC) in the absence of active infection or previous coagulation disorders. It mainly affects the pediatric population and, in 90% of cases, it is preceded by an infectious process. The pathophysiological mechanism is a transient autoantibody-mediated protein S deficiency that favors a hypercoagulable state. Here we describe the case of a previously healthy 8-year-old boy with purpuric skin lesions typical of purpura fulminans associated with DIC in the absence of sepsis. A transient plasma protein S deficiency was confirmed. He required replacement therapy with fresh frozen plasma and anticoagulation; he had a favorable course. Protein S activity remained decreased for 2 months.


La púrpura fulminante adquirida postinfecciosa es una entidad aguda y grave, poco frecuente, caracterizada por necrosis cutánea asociada a coagulopatía intravascular diseminada (CID), en ausencia de infección activa o alteraciones previas de la coagulación. Afecta fundamentalmente a la población pediátrica y, en el 90 % de los casos, está precedida por un proceso infeccioso. El mecanismo fisiopatológico es un déficit transitorio de proteína S mediado por autoanticuerpos que favorece un estado de hipercoagulabilidad. Se presenta el caso de un varón de 8 años previamente sano, con lesiones cutáneas purpúricas características de púrpura fulminante asociada a CID en ausencia de sepsis. Se constató deficiencia plasmática transitoria de proteína S. Requirió tratamiento sustitutivo con plasma fresco congelado y anticoagulación; la evolución fue favorable. La actividad de la proteína S permaneció disminuida durante 2 meses.

RESUMO

Purpura fulminans is a severe coagulation disorder that often leads to death in neonates. Mutations in the protein C (PROC) gene can cause protein C deficiency, leading to this disorder. This study aimed to investigate a family with a history of coagulopathies, particularly those related to protein C deficiency. The primary objective was to identify any genetic mutations in the PROC gene responsible for the coagulopathies. The study focused on a male neonate with purpura fulminans who ultimately died at 2 months of age. The patient had low protein C activity levels (6%). The entire PROC gene of the patient and his family was analyzed using next-generation sequencing to identify any genetic mutations. Segregation analysis was conducted to determine if the mutation followed an autosomal dominant inheritance pattern. In silico analysis was also conducted to evaluate the pathogenicity of the identified mutation. Analysis revealed a novel homozygous c.1243T>G variant PROC gene. The mutation resulted in a Phe415Val substitution. The mutation was found in at least three generations of the family. Carrier family members had lower protein C activity levels than wild-type homozygotes. Additionally, the mutation may account for the observed reduction in protein C enzyme activity.

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

Background: IgA vasculitis and hypersensitivity reactions following exposure to non-steroidal anti-inflammatory drugs (NSAIDs) are very rarely associated with purpura fulminans (PF). The latter is a coagulation event characterised by decreased levels of protein C and a rapidly progressive purpuric rash, often leading to ischaemia, amputations and death. Case summary: A previously healthy 66-year-old man presented with a vasculitic rash and abdominal pain following exposure to naproxen (NSAID), which quickly deteriorated to purpura fulminans-like eruption and skin necrosis, mainly involving the face and hands. The presence of IgA sediments on skin biopsy and decreased levels of complement as well as protein C pointed to an immune-mediated inflammatory process. Dramatic clinical escalation with immediate risk to organs and life required an aggressive and broad-spectrum therapeutic approach in an intensive care setting. Clinical improvement and complete reconstitution of protein C were achieved following plasma exchange with fresh frozen plasma (FFP) and immunosuppression with glucocorticoids with no persistent organ damage. Conclusions: This rare case illustrates the catastrophic cross links between NSAIDs, IgA-mediated hypersensitivity vasculitis and purpura fulminans-like syndrome. A high index of suspicion is required for the evaluation of environmental exposures such as drugs and infections in patients with vasculitis and/or purpura. A rapid and comprehensive therapeutic approach should be implemented to avoid multi-organ damage, amputations and death. Complete avoidance of the offending agent is key for future prevention of recurrence. LEARNING POINTS: This case illustrates a rare cross link between a commonly used drug (NSAIDs) and severe, life-threatening hypersensitivity reactions (IgA vasculitis and purpura fulminans-like eruption).These events require a high index of suspicion and emphasise the importance of considering environmental exposures such as drugs in the immediate diagnosis of both conditions.In addition to long-term drug avoidance, early and aggressive interventions are required to avoid organ damage, amputations or death.

RESUMO

Purpura fulminans (PF) is a disorder with multifactorial causes that lead to acute localize skin microvasculature thrombosis. PF can be classified as one of the manifestations of disseminated vascular coagulation (DIC). Although, there are three types of PF including hereditary (autosomal dominant) due to mutations in single nucleotide polymorphisms (PROC and PROS1) and serpin family C member 1 (SERPINC1) genes. Idiopathic or acquired type of PF is complex and the pathophysiology is ambiguous, however, low levels of protein C and S were observed. The acute infectious form of PF occurs post-bacterial infection (e.g., Neisseria). The clinical presentation is limited to skin findings or systematic manifestation (shock, disseminated intravascular coagulation, or death). We are presenting two cases of PF sharing similar clinical manifestations developed within 12 h post-operatively with distinct micro-organisms infection. The first patient's wound culture grew fluffy mold, and the sequencing confirmed a Mucormycosis, Absidia corymbifera species, while the second patient was infected by cutaneous Candida glabrata which led to the development of PF. Our findings suggest that surgery can trigger local immunological responses in susceptible individuals such as concealed protein C and S deficiency or microorganism toxins that initiated the rapidly developing of PF in those patients.

RESUMO

BACKGROUND: Case reports of symmetric digital gangrene resulting from high-dose vasopressors use in patients with alcoholic ketoacidosis, leading to cardiac arrest, are rare. To date, no specific treatment method for autolysis or surgical amputation or guidelines for determining the level of amputation have been established. CASE SUMMARY: In this case report, we describe a treatment method that effectively preserved the function of fingers by surgical treatment under local anesthesia with a minimum operative time, while also preserving finger length to the maximum possible extent. CONCLUSION: Our approach may contribute to improved postoperative quality of life by preserving finger length.

RESUMO

Introduction: Purpura fulminans in the neonatal population is a rare but potentially life-threatening condition complicated by thrombosis, resultant vital organ necrosis, and gangrene of the extremities. Considering the rapid evolution of the pathogenetic mechanism, an index of suspicion, early identification, and prompt intervention are imperative for improved outcomes. The majority of purpura fulminans cases have an infectious etiology, but it is essential to consider other congenital and acquired causes. Case description: We present a clinical case of a female neonate to emphasize the correlation between purpura fulminans, congenital chylothorax, involvement of the PAK2 gene, and the occurrence of retinal detachment in both eyes. After draining the congenital chylothorax, the neonate developed purpura fulminans due to a loss of protein C, S, and antithrombin factors, previously not reported in the literature. The purpuric lesions resolved after the administration of fresh frozen plasma. Subsequently, no recurring purpura fulminans lesions were noted following the normalization of the antithrombotic factor levels in the serum. Subsequently, the child also developed retinal detachment in both eyes.

RESUMO

Post-splenectomy patients are at increased risk of infection. This complication is called overwhelming post-splenectomy infection (OPSI), which is uncommon but has high mortality. We describe a case of a man in his 80s who presented with septic shock with purpura fulminans caused by pyelonephritis. He had undergone a splenectomy in his 50s and had been taking prednisolone for the past six months for suspected immunoglobulin G4 (IgG4)-related disease. He was admitted to the intensive care unit but died the day after admission. OPSI is generally caused by encapsulated bacteria. However, in the present case, the causative agent was Escherichia coli, a bacterium that typically causes urinary tract infections. Post-splenectomy patients are known to have compromised bacterial clearance, and accumulation of bacteria such as E. coli can induce acute sepsis after splenectomy. Thus, physicians must have a high index of suspicion when treating splenectomy patients for the possibility that they may rapidly deteriorate to severe conditions such as OPSI, and the patients must be informed about the risk of severe infections, which can be fatal.

RESUMO

Introduction: Infection due to Capnocytophaga canimorsus may result in a wide variety of clinical presentations. We present a case of life-threatening Capnocytophaga canimorsus infection with evolution of ecchymosis to purpura fulminans. Case description: We present a case of a 43-year-old male with a history of excessive alcohol consumption who presented with features of sepsis following a dog bite. This was associated with a striking, widespread purpuric rash. A causative pathogen, C. canimorsus was identified through blood culture and 16S RNA sequencing. His initially purpuric rash underwent bullous transformation and was diagnosed clinically as purpura fulminans, confirmed on skin biopsy. He made a full recovery with prompt antimicrobial therapy, initially with co-amoxiclav but escalated to clindamycin and meropenem due to clinical deterioration and concerns of beta-lactamase resistance. Discussion: ß-Lactamase producing Capnocytophaga strains are of increasing concern. This particular concern is reflected in our case as 5 days into treatment with ß-lactamase inhibitor combination therapy the patients clinical condition deteriorated but demonstrably improved on switching to a carbapenem.The development of biopsy proven purpura fulminans in this immunocompetent case is a rare severe manifestation of the previously reported manifestation of disseminated intravascular coagulation (DIC) in Capnocytophaga bacteraemia. The case reported describes characteristics common with other DIC presentations such as the presence of clinical risk factors (history of excessive alcohol consumption) and symmetrical involvement. However, an unusual feature in that initial purpuric lesions were followed by the development of a bullous appearance and peripheral necrotic features concerning for purpura fulminans and confirmed with skin biopsy.

RESUMO

Purpura fulminans (PF) is a rare presentation of disseminated intravascular coagulopathy (DIC) and a life-threatening complication of septic shock. DIC can present with bleeding and thrombosis in acute settings, making its management exceptionally challenging. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, andHaemophilus influenzae. We report a case of a 47-year-old patient with a history of alcohol abuse and marijuana use with a bizarre presentation of copious diarrhea and altered mental status. The patient was subsequently admitted to the intensive care unit (ICU) for acute respiratory failure and septic shock secondary to Streptococcus pneumoniae bacteremia complicated by DIC. Unfortunately, the patient's condition worsened with multiorgan failure and purpura fulminans, leading to extensive necrosis of all his extremities, with the involvement of his lips, nose, and genitals. Unfortunately, despite aggressive interventions, he continued to deteriorate and ultimately was transitioned to comfort care before he expired. In the literature, there is only one reported case of PF in an individual with alcohol abuse. However, the frequency and severity of pneumococcal infections in individuals with a history of alcohol abuse are much higher than in the general population. PF is a devastating complication of Streptococcus pneumoniae, with a mortality of 43%. We hope that this case will continue highlighting the importance of vaccinating patients with a history of alcohol abuse with the pneumococcal vaccine.

RESUMO

Introduction: Idiopathic purpura fulminans (IPF) is a rare and severe coagulation disorder, associated with transient anti-protein S (anti-PS) antibodies in the context of post-viral infection such as varicella. Anti-protein S antibodies are frequently found in the context of varicella, in contrast with the rarity of IPF. Other factors such as anti-phospholipid antibodies (APL) and inherited thrombophilia may be associated with severe vascular complication. Method: This is an ancillary study of a French multicenter retrospective series and systematic review of literature. We analyzed patients who were tested for inherited thrombophilia, namely antithrombin, protein C, protein S deficiency; prothrombin gene G20210A polymorphism (FII:G20210A),Factor V R506Q polymorphism (FV:R506Q); and/or for APL (lupus anticoagulant (LA), anti-cardiolipin antibodies (ACL), or anti-beta 2-GPI antibodies (Aß2GP1). Results: Among the 25 patients tested for inherited thrombophilia, 7 (28%) had positive results. Three had FV R506Q, two FII:G20210A, one compound heterozygote FV:R506Q associated to FII:G20210A, and one protein C deficiency. APL testing was performed in 32 patients. It was positive in 19 patients (59%): 17 ACL (53%), 5 LA (16%), 4 Aß2GP1 (13%). The risk of severe complications was not associated with presence of inherited thrombophilia or APL presence, with RR: 0.8 [95% CI: 0.37-1.71], p = 1 and RR: 0.7 [95% CI: 0.33-1.51], p = 0.39, respectively. We found a high prevalence of inherited thrombophilia or APL in a population of patients with IPF. However, we do not find an association with the occurrence of severe vascular complications or venous thromboembolism.
