Interesting Mucocutaneous Manifestations in COVID-19 Infection or Vaccination Confirmed by Histopathology: A Case Series

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.

Efficacy and safety of a hyperoxygenated fatty acid compound in improving the microcirculation of purpura fulminans in paediatric patients with sepsis: a pilot study

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 4h 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. In more than half of the episodes analysed, an increase in tissue microcirculation was observed after the application of HOFAs, with no adverse events.

Development of purpura fulminans by Candida glabrata and Mucormycosis infection post-surgery

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.

Preserving finger length in a patient with symmetric digital gangrene under local anesthesia: A case report

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.

Skin biopsy in adult patients with meningococcal purpura fulminans: a multicenter retrospective cohort study

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.

An Uncommon Presentation of Vasopressin-Induced Purpura Fulminans

Purpura fulminans (PF) is a rarely encountered rapidly evolving dermatological manifestation of ischemia, particularly in critically ill patients. Considered one of the very few dermatological emergencies, it has high mortality rate where patients often succumb to the illness. It can manifest in three forms: neonatal, idiopathic, and the more commonly infectious variety, which can be secondary to mostly bacterial and rarely viral etiology. It is also reported to be highly associated with disseminated intravascular coagulation (DIC), heparin-induced thrombocytopenia (HIT), and acute hepatic failure (AHF). Hereditary or acquired deficiency of protein C and dysregulation of the coagulation cascade, mainly protein C-thrombomodulin, has been implicated in the pathogenesis. We present a 55-year-old male admitted to the intensive care unit for diabetic ketoacidosis (DKA) and septic shock. Along with initiating management protocol for DKA and broad-spectrum antibiotics, he was initially started on norepinephrine for septic shock. Because of persistent refractory septic shock, he was subsequently initiated on phenylephrine and vasopressin to maintain adequate perfusion. The following day, he was found to have sharply demarcated blackish non-blanching discoloration on bilateral knees, lower limbs, and scrotum, sparing the acral regions. This cutaneous manifestation persisted throughout his hospital course, although it improved after discontinuation of vasopressin while continuing with other pressors. Vasopressin has been implicated in a few instances of skin necrosis; however, PF has rarely been documented and never within 1 day like ours. This case demonstrates a unique development of PF likely from vasopressin after ruling out the diagnoses of DIC, HIT, thrombotic thrombocytopenic purpura, and AHF.

Venoarterial extracorporeal membrane oxygenation treatment for acute respiratory distress syndrome and non-occlusive mesenteric ischemia due to Pasteurella multocida-related sepsis with purpura fulminans: a case report

BACKGROUND

Pasteurella multocida-related sepsis can cause purpura fulminans (PF), a rare thrombotic disorder that often presents acutely and is potentially fatal. As a consequence of disseminated intravascular coagulation, this hematological emergency originates from micro-thrombotic occlusion of peripheral blood vessels and resulting circulatory failure. Thus far, no studies have reported the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for saving lives in patients with worsening respiratory and circulatory failure. Moreover, the development of non-occlusive mesenteric ischemia after VA-ECMO has not yet been documented. Here, we describe the case of a 52-year-old female patient with PF and non-occlusive mesenteric ischemia due to Pasteurella multocida-related sepsis who received VA-ECMO.

CASE PRESENTATION

A 52-year-old-female patient presented to the hospital with a week-long fever and worsening cough. Chest radiography findings revealed ground-glass opacity. We made a diagnosis of acute respiratory distress syndrome due to sepsis and initiated ventilatory management. Because respiratory and circulatory parameters were not maintained, VA-ECMO was introduced. After admission, ischemic findings were observed in the periphery of the extremities, and a diagnosis of PF was made. Pasteurella multocida was detected in blood cultures. On day 9, the sepsis was cured with antimicrobial treatment. The patient's respiratory and circulatory status improved, and she was weaned off VA-ECMO. However, on day 16, her stable circulatory system collapsed again, and her abdominal pain worsened. We performed exploratory laparotomy and noted necrosis and perforation of the small intestine. As a result, partial resection of the small intestine was performed.

CONCLUSION

In this case, VA-ECMO was used to maintain circulatory dynamics during septic shock in a patient with Pasteurella multocida infection who developed PF. Surgery was also performed for complicated ischemic necrosis of the intestinal tract, helping save the patient's life. This development illustrated the importance of paying attention to intestinal ischemia during intensive care.

Fulminans Purpura due to Morganella morganii

Purpura fulminans (PF) is a dermatological manifestation of a life-threatening condition characterized by disseminated intravascular coagulation and endovascular thrombosis. The idiopathic/infectious form is the most common and usually associated with infection by Neisseria meningitidis or Streptococcus pneumoniae. We describe a case of Morganella morganii-induced bacteriaemia complicated with PF in an individual who had undergone a recent urinary tract infection intervention. The patient presented with purpuric skin lesions, fever and hypotension but had no alterations in coagulation parameters or disseminated intravascular coagulation. Aggressive early resuscitation, intravenous antibiotics and wound care were essential to a favourable response.

LEARNING POINTS

Purpura fulminans is a dermatological manifestation of an underlying life-threatening condition, and is characterized by disseminated intravascular coagulation and skin necrosis.It is a morbid and potentially fatal condition that can be a cutaneous manifestation of Morganella morganii bacteraemia.Early identification and accurate diagnosis of the underlying cause can help minimize morbidity and mortality; management should be tailored to the individual, with the use of intravenous antibiotics, necrotic skin excision and aggressive early resuscitation.

Purpura fulminans due to Enterococcus cecorum in an asplenic patient

Enterococcus cecorum was initially isolated from the intestine of poultry and is an uncommon cause of human infection. We report here what we believe to be the first case of overwhelming post-splenectomy infection (OPSI) with purpura fulminans due to Enterococcus cecorum in a 51-year-old man. As opposed to other enterococci, Enterococcus cecorum remains susceptible to third-generation cephalosporin which is the first line empirical antibiotic therapy for both patients with purpura fulminans and asplenic patients with sepsis. Despite adequate antibiotic therapy, evolution in the intensive care unit (ICU) was overwhelming with death occurring 10 h after ICU admission.

Capnocytophaga sepsis causing purpura fulminans in a 50-year-old man with chronic opioid use

We present a case of polymicrobial sepsis with Capnocytophaga spp. complicated by purpura fulminans following a dog-bite in a 50-year-old-man with an extensive history of opioid use disorder. Generally, severe Capnocytophaga cases are thought to occur in patients with underlying immune deficiencies. However, this case highlights the importance of maintaining clinical suspicion for Capnocytophaga infection in immunocompetent patients, and we discuss the role of chronic opioid-use in severe infection.

Prevalence and clinical features of secondary skin lesions in septic patients with bloodstream infections

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.

Clinical and genetic features of Chinese pediatric patients with severe congenital protein C deficiency who first presented with purpura fulminans: A case series study and literature review

INTRODUCTION

Purpura fulminans (PF) is a hematological emergency that can be caused by severe congenital protein C (PC) deficiency. It has been rarely reported in the Chinese population. We aimed to characterize the clinical and genetic features of Chinese pediatric patients with severe congenital PC deficiency who first presented with PF.

MATERIALS AND METHODS

Twelve pediatric patients were diagnosed with severe congenital PC deficiency with PF, which was diagnosed based on our hospital records and previous reports from 1988 to July 2021 in China. We evaluated the clinical and genetic features of these patients.

RESULTS

Nine patients (9/12, 75%) had onsets that were observed within the first 48 h after birth. Six patients had a family history of thromboembolism. There was no consanguinity. Other symptoms were intracranial thrombosis or hemorrhage (4, 33.3%), ocular lesions (2, 16.7%), gastrointestinal hemorrhage (2, 16.7%) and kidney infarction before birth (1, 8.3%). All but one of the patients (one case not detected) had a plasma PC activity of <10%. The genetic study indicated that in the eight patients with inherited PC deficiency, two were homozygous, five were compound heterozygous and one was heterozygous for PC deficiency.

CONCLUSION

This is the first and largest case series of Chinese pediatric patients with severe congenital PC deficiency who first presented with PF. It has been shown that treatment with both fresh frozen plasma and anticoagulants is recommended when PC concentrate is not easily available, especially in developing countries.

Free flap for lower limb salvage in infectious purpura fulminans

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.

Purpura fulminans following hump-nosed pit viper (Hypnale hypnale) envenoming: A rare complication of snakebites

Hump-nosed pit vipers of the genus Hypnale are highly venomous and reputed for the commonest venomous snakebites in Sri Lanka. They frequently cause local manifestations and less commonly cause systemic effects such as acute kidney injury and coagulopathy. There is no antivenom currently available in Sri Lanka for their envenoming. However, more and more complications of Hypnale bites are being recently described. Purpura fulminans, one of the rare complications of snakebites that we report following authentic Hypnale hypnale bite. A 58-year-old female was bitten by a hump-nosed viper and developed bilateral toe gangrenes, ultimately ended up with amputations. She got recovered with loss of toes in both feet for 46 days treatment at hospital.

A rare association between group A Streptococcus purpura fulminans and diffuse alveolar hemorrhage in a young girl: A case report

We report the case of a 7-year-old girl with septic shock and coagulopathy associated with purpura fulminans (PF) and diffuse alveolar hemorrhage (DAH) due to group A Streptococcus (GAS) infection identified with 16S ribosomal RNA analysis performed on the skin biopsy. GAS infection with PF associated with DAH is rare in healthy young children but pediatricians should be aware of this condition because of the poor prognosis. The initial treatment for circulatory failure and severe disseminated intravascular coagulation as well as the prompt initiation of antibiotic treatment may be crucial for the outcomes of S. pyogenes PF.

Skin and sepsis: contribution of dermatology to a rapid diagnosis

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).

Early fasciotomies and plastic-surgical reconstruction may enhance preservation of functional extremity length in purpura fulminans

BACKGROUND

Purpura fulminans (PF) is a distinct form of rare meningococcal septicaemia mostly in childhood which is characterized by high lethality, extensive necroses and mutilations of extremities. Other ethiologies are idiopathic forms or purpura neonatorum, which is marked by deficiency of Protein-C. PF is caused by micro-embolism of the vascular system, followed by quickly spreading necroses of skin and different organs.Modern concepts of intensive care treatment of the acute phase of this disease and early surgical intervention lead to a rising number of surviving patients requiring limb salvage.Aim of this study is to evaluate a possible lower morbidity and the grade of lower loss of function because of early surgical intervention.

PATIENTS AND METHODS

Between the years 1998 and 2017 eight cases of PF at two large centers for critical wound care, the department of plastic-, hand- and reconstructive surgery of the university hospital of Regensburg and the department of plastic-, hand- and reconstructive surgery of the BG-clinic Ludwigshafen were included into our study.We retrospectively examined patients with PF who were stabilized by intensive care medicine and received surgical interventions. After survival of the acute phase (10 days), patients received plastic surgical reconstructions.

RESULTS

A total number of eight patients could be included into our study. All patients survived the initial phase (10 days). All patients required plastic-surgical interventions to address extensive skin and soft tissue defects. Flap operations were judged necessary in five cases. Hereby four defects could be reconstructed by free tissue transfer, one with a local flap. Flap survival was 100 percent. One flap required revision of the arterial anastomosis of the flap arteria. Another flap got partial necrosis. One patient died due to multiorgan failure.Early debridements with consequent fasciotomies and secondary plastic-surgical reconstruction achieved good functional results. Limb salvage was accomplished in three patients. One patient died due to fulminant progress of the disease.

CONCLUSION

Management of PF requires a multidisciplinary approach and close communication between the different subspecialties. Early debridements with consequent fasciotomies showed good results in salvaging subfascial muscle tissue in the extremities with satisfying functional results. Early surgical intervention is an important factor for improved limb salvage and survival.

Clinical and Histopathologic Characteristics of the Main Causes of Vascular Occlusion - Part I: Thrombi

La patología vascular oclusiva es causante de diversas y variadas manifestaciones clínicas, algunas de las cuales son de catastróficas consecuencias para el paciente. Sin embargo, las causas de tal oclusión son muy variadas, extendiéndose desde trombos por acción descontrolada de los mecanismos de coagulación, hasta anomalías de los endotelios de los vasos u oclusión por materiales extrínsecos. En una serie de dos artículos hacemos una revisión de las principales causas de oclusión vascular, resumiendo sus manifestaciones clínicas principales y los hallazgos histopatológicos fundamentales. Esta primera parte corresponde a las oclusiones vasculares que cursan con trombos.

Severe Protein C Deficiency due to Novel Biallelic Variants in PROC and Their Phenotype Correlation

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.

Use of hyperbaric oxygen therapy of purpura fulminans in an extremely low birth weight preterm: A case report

Purpura fulminans (PF) is a rare and fatal complication of septic shock or diffuse intravascular coagulation (DIC) resulting in skin and soft tissue necrosis. PF can be caused by congenital or acquired protein C (PC) or protein S (PS) deficiency. The most common cause of PF in a neonate is sepsis. In our extremely low birth weight preterm case, due to PF that started in the right-hand fingers, examination was made and protein S deficiency was detected as well as MTHFR (A1298C) and Factor V Leiden (R506Q) homozygous mutations. While being unresponsive to fresh frozen plasma (FFP) and unfractionated heparin (UFH) therapy, we want to highlight the curative treatment with hyperbaric oxygen (HBOT), which has not previously been used in extremely low birth weight preterm infants for this purpose.

Refractory gram-negative septic shock complicated by extended purpura fulminans and multiple organ failure in a 23-year-old puerpera -a case report

Background

Pregnancy-related infections are the third most common cause of maternal death worldwide. The aim of this report is to present a case of pregnancy-related infection, which progressed into refractory septic shock accompanied by purpura fulminans and multiple organ failure.

Case

A 23-year-old woman in the postpartum period developed fulminant, refractory septic shock complicated by purpura fulminans and multiple organ failure syndrome (acute respiratory distress syndrome, acute kidney injury, and encephalopathy). Management included antibacterial therapy, fluid and transfusion therapy, nutritional support, protective mechanical ventilation, hydrocortisone, a large dose of ascorbic acid, and thiamine. There were no neurological consequences and all organ functions returned to normal, although the predicted hospital mortality based on the Sequential Organ Failure Assessment (SOFA) score was more than 90%.

Conclusions

Septic shock is a significant, yet not completely understood life-threatening condition, which can be associated with purpura fulminans, multiple organ dysfunction, disseminated intravascular coagulation, and massive tissue necrosis.

Acute infectious purpura fulminans: a case series from India

Acute infectious purpura fulminans is a serious, potentially fatal condition. We present a case series of 11 patients from March 2005 to March 2017, whose clinical symptoms were fever (100%), confusion (63.6%) and headache (55%), and whose common laboratory abnormalities were thrombocytopenia (100%), elevated alkaline phosphatase (70%) and anaemia (63.6%). Three patients (27%) developed gangrene and two presented in shock. Only one grew Neisseria meningitidis in cerebrospinal fluid (CSF) culture and another confirmed by latex agglutination and polymerase chain reaction in CSF. Five others had serology confirmed spotted fever rickettsioses (SFG). All received broad spectrum antibiotics; in 9/11 patients, this included doxycycline or azithromycin. The mean hospital stay was 10.2 days and overall mortality was 18.2%.

Hemophagocytic syndrome with severe sepsis caused by Capnocytophaga canimorsus

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.

Pneumococcal purpura fulminans in asplenic or hyposplenic patients: a French multicenter exposed-unexposed retrospective cohort study

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.

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.
