Outcomes and management of pregnancy and puerperal group A streptococcal infections: A systematic review.

INTRODUCTION: Group A streptococcus (Streptococcus pyogenes) is one of the most lethal bacterial pathogens of humans, with increased risk of progression to septic shock and multiorgan failure in the pregnant population. The objective of this study is to systematically review the outcomes and management strategies for pregnancy and puerperal group A streptococcus infections in an effort to provide further guidance for prevention and treatment of a rare but lethal infection worldwide. MATERIAL AND METHODS: A comprehensive search using puerperium and streptococcus pyogenes terms was completed across several registered databases. A total of 902 articles investigating pregnancy and puerperal group A streptococcus infection were identified, with 40 studies fulfilling inclusion criteria of original research articles in humans published from 1990 onwards reporting four or more unique cases of group A streptococcus in pregnancy or postpartum. This study was registered in PROSPERO: CRD42020198983. RESULTS: A total of 1160 patients with pregnancy and puerperal group A streptococcus infection were identified. Most infections occurred postpartum (91.9%), with 4.7% reported antepartum and 0.6% intrapartum. Bacteremia was present in 49.0% of patients and endometritis in 45.9%. Puerperal sepsis was described in 28.2% of cases and progressed to streptococcal toxic shock syndrome in one-third of such cases. Overall, the case fatality ratio was 2.0%, with one-third of the deaths from antenatal cases including 3/22 (13.6%) cases of septic abortion and 10/46 (21.7%) antenatal cases of group A streptococcus infection. CONCLUSIONS: Group A streptococcus infection remains an important contributor to pregnancy and puerperal morbidity and mortality. Early recognition, diagnosis and aggressive management are important for favorable outcomes given the serious risk of sepsis and streptococcal toxic shock syndrome.

Impact of local terminology on the design of a community-based diagnostic and management algorithm for postpartum sepsis: findings of formative research.

BACKGROUND: Postpartum sepsis is one of the leading causes of maternal mortality and morbidity in developing countries. This formative research elicits local terms used for postpartum illnesses and symptoms of postpartum sepsis with the aim of improving postpartum diagnosis and management in Pakistan. METHODS: We conducted 34 in-depth interviews with recently delivered women (RDW), traditional birth attendants (TBAs), healthcare providers and family members of RDW from rural Sindh to explore local Sindhi terms used to describe postpartum sepsis and related symptoms. During interviews, all participants were asked to orally free list common symptoms of postpartum illnesses; those who were aware of the concept were asked to free list possible symptoms of postpartum sepsis. The responses were recorded by the interviewer. Free listing data were analyzed for frequency and salience. RESULTS: Most participants, including TBAs, were not familiar with the concept of postpartum sepsis as a distinct disease or of a local term denoting the concept. Almost all could identify and report symptoms related to postpartum sepsis in the local language. Only physicians were able to recognize the term postpartum sepsis and related symptoms. Multiple local terms were used for a particular symptom; still others were used to denote gradations of severity. 'Bukhar' (fever) was the most commonly named symptom although it was often considered a normal part of puerperium. Many postpartum illnesses were related to the highly non-specific local term 'kamzori' (weakness). CONCLUSIONS: Better awareness about local terminology used in rural areas related to postpartum sepsis could improve communication, care-seeking patterns, diagnosis and management.

New obstetric systemic inflammatory response syndrome criteria for early identification of high-risk of sepsis in obstetric patients.

OBJECTIVES: We aimed to establish new cut-off values for SIRS (Systemic Inflammatory Response Syndrome) variables in the obstetric population. METHODS: A prospective cohort study in pregnant and postpartum women admitted with systemic infections between December 2017 and January 2019. Patients were divided into three cohorts: Group A, patients with infection but without severe maternal outcomes (SMO); Group B, patients with infection and SMO or admission to the intensive care unit (ICU); and Group C, a control group. Outcome measures were ICU admission and SMO. The relationship between SIRS criteria and SMO was expressed as the area under the receiver operating characteristics curve (AUROC), selecting the best cut-off for each SIRS criterion. RESULTS: A total of 541 obstetric patients were enrolled, including 341 with infections and 200 enrolled as the reference group (Group C). The patients with infections included 313 (91.7%) in Group A and 28 (8.2%) in Group B. There were significant differences for all SIRS variables in Group B, compared with Groups A and C, but there were no significant differences between Groups A and C. The best cut-off values were the following: temperature 38.2 °C, OR 4.1 (1.8-9.0); heart rate 120 bpm, OR 2.9 (1.2-7.4); respiratory rate 22 bpm, OR 4.1 (1.6-10.1); and leukocyte count 16,100 per mcl, OR 3.5 (1.6-7.6). CONCLUSIONS: The cut-off values for SIRS variables did not differ between healthy and infected obstetric patients. However, a higher cut-off may help predict the population with a higher risk of severe maternal outcomes.

Public Health Agency of Sweden's Brief Report: Pregnant and postpartum women with severe acute respiratory syndrome coronavirus 2 infection in intensive care in Sweden.

The Public Health Agency of Sweden has analyzed how many pregnant and postpartum women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been treated in intensive care units (ICU) in Sweden between 19 March and 20 April 2020 compared with non-pregnant women of similar age. Cases were identified in a special reporting module within the Swedish Intensive Care Registry (SIR). Fifty-three women aged 20-45 years with SARS-CoV-2 were reported in SIR, and 13 of these women were either pregnant or postpartum (<1 week). The results indicate that the risk of being admitted to ICU may be higher in pregnant and postpartum women with laboratory-confirmed SARS-CoV-2 in Sweden, compared with non-pregnant women of similar age.

Invasive Group A streptococcal postpartum endometritis associated with multi-organ infarctions: an uncommon case presentation and literature review.

Background: Streptococcal Toxic Shock Syndrome (STSS) is a serious condition that can arise from streptococcal postpartum endometritis. It is associated with a substantial increase in mortality rate and can rarely result in multiorgan infarction. Early recognition plays a vital role in patients' outcome. Objective: To report a case of complicated STSS and review the literature for previous case reports of streptococcal postpartum endometritis to determine if STSS diagnostic criteria (published by the Centers for Disease Control and Prevention) were fulfilled. Case presentation: This is a 41-year-old woman who presented 5 days after an uncomplicated vaginal delivery with endometritis complicated by invasive group A ß-hemolytic streptococcus (GAS) infection and confirmed toxic shock syndrome. The patient was initially admitted to the critical care unit due to hemodynamic compromise requiring intravenous (IV) fluids, IV antibiotic therapy with penicillin and clindamycin, and IV immunoglobulin therapy. The patient subsequently developed multi-organ infarctions, acute respiratory distress syndrome requiring noninvasive respiratory support, and severe reactive arthritis. Literature review revealed 15 case reports of GAS postpartum endometritis, five met criteria for confirmed STSS. One patient died from severe septic shock leading to cardiopulmonary arrest. Thirteen out of 15 cases of postpartum endometritis occurred after uncomplicated vaginal delivery. Conclusion: STSS is a serious and possibly fatal medical condition that requires early diagnosis and treatment to prevent poor patient outcomes and death. Careful consideration to the patient's postpartum clinical presentation with the implementation of an intradisciplinary approach should be utilized.

Ignaz Semmelweis: a victim of harassment?

Ignaz Semmelweis' (1818-1865) discovery of the endemic causes of febris puerperalis is a striking example of the role of pathology in medicine. Transdisciplinarity encounters Semmelweis' biography, which is neither linear nor totally focused on medicine. He completed the philosophicum (artisterium), studying the septem artes liberales (1835-1837) in Pest, comprising humanities and natural science. After moving to Vienna, he began to study law, but turned to medicine as early as 1838. In 1844, he graduated with a botanical doctoral thesis composed in Neo-Latin, showing linguistic and stylistic talent and a broad knowledge of gynecology and obstetrics. The style and topoi demonstrate the interchangeability of what he learnt during his propaedeuticum. Nowadays, hardly anyone is familiar with this booklet, for two main reasons: the language choice and the life-saving impact of the physician's opus magnum on the reasons for puerperal fever (Die Aetiologie, der Begriff und die Prophylaxis des Kindbettfiebers). In later life, he became convinced that he had no talent as a (scientific) author-a fatal error that led him to become a victim of what we now call "publish or perish." Semmelweis had felt rejected for years. This negative feeling was the reason for his decision not to publish his great book for 14 years. When it finally went to the printer in 1861, the scientific community did not accept it. This experience caused psychosomatic symptoms owing to his long-standing and deeply felt disappointment. Bad conscience tortured him. This permanent stress destroyed his health: in 1865, his relatives (including his wife) and friends took him from Budapest to Vienna. He thought he was going to spend some time relaxing, but in fact was led into a newly built asylum for the mentally ill, the Niederösterreichische Landesirrenanstalt. When he realized what was happening, he tried to escape. Badly abused, he died from sepsis caused by open wounds and a dirty straightjacket 2 weeks later. This article will show Semmelweis to be a multilingual author of scientific literature and (open) letters; it will present him as a researcher who became a victim of harassment and what is referred to as the "Semmelweis reflex" ("Semmelweis effect"); and it will focus on his afterlife in (children's) literature, drama, and film.

Abdominal computed tomography (CT) scan in the evaluation of refractory puerperal fever: impact on management.

Introduction: Computed tomography (CT) imaging should be employed judiciously, given its cost, use of intravenous contrast, and ionizing radiation. The aim of this study was to determine the clinical benefit of a CT scan in the evaluation of refractory puerperal fever and to identify the appropriate candidates for its use.Methods: This was a retrospective cohort study conducted in a single tertiary care center between January 2007 to April 2017. Indications for CT scan were refractory postpartum fever of ≥3 days and/or ultrasound findings suggesting complex abdominal fluid collection. Primary outcome was defined as a change in the mode of treatment due to the CT findings. In addition, a multivariate analysis of risk factors for puerperal fever was performed to identify patients who would benefit from the CT scan evaluation.Results: There were 520 women that underwent an abdominal and pelvic CT scan during the study period, 238 (45.7%) met inclusion criteria, 94 (39.5%) had a normal CT scan, and 144 (60.5%) had abnormal findings including 32 (13.4%) cases with pelvic thrombophlebitis and 112 (47%) cases with pelvic fluid collections. Results of the CT changed clinical management in 93 (39.0%) patients, including: switching antibiotics in 24 (10%) patients, adding low molecular weight heparin for 28 (11.8%) patients, and surgical intervention (laparotomy or drainage insertion) in 41 (17.2%) patients. In the regression model, we didn't find any significant risk factors associated with treatment change following the CT scan.Conclusions: Abdominal and pelvic CT scan in women with refractory puerperal fever has a high clinical yield and lead to a change in management in a substantial number of patients.

From septicemia to sepsis 3.0-from Ignaz Semmelweis to Louis Pasteur.

Sepsis remains a contemporary threat, and its frequency remains high amongst an aging population. Its definition has been regularly revisited, but the impact of the translational research studying it remains very modest compared to the results seen after the introduction of hygiene and the use of antibiotics. In the past, the main forms of sepsis were hospital gangrene (also known as nosocomial fever or putrid fever) that affected the wounded, and puerperal fever that affected women shortly after delivery. In 1858, Armand Trousseau stated that these two pathologies were identical. Lucrezia Borgia, who died in 1519, is undoubtedly the most famous woman to die from puerperal fever. The notion of sepsis as a real epidemic was deplored. For decades doctors remained deaf to the recommendations of their clairvoyant colleagues who advocated for the use of hygienic measures. It was as early as 1795 that Alexander Gordon (UK) and later in 1843, Oliver Holmes (USA), called for the use of hygienic practices. In 1847, Ignaz Semmelweis, a Hungarian physician, provided an irrefutable demonstration of the importance of hygiene in the prevention of contamination by the hands of the practitioners. But Ignaz Semmelweis' life was a tragedy, his fight against the medical nomenklatura was a tragedy, and his death was a tragedy! Nowadays, Ignaz Semmelweis is receiving the honor that he deserves, but never received during his life. Carl Mayrhofer, Victor Feltz, and Léon Coze were the first to associate the presence of bacteria with sepsis. These observations were confirmed by Louis Pasteur who, thanks to his prestige, had a great influence on how to undertake measures to prevent infections. He inspired Joseph Lister who reduced mortality associated with surgery, particularly amputation, by utilizing antiseptic methods.

A Challenging Case of Retroperitoneal Abscess in a Post-Partum Crohn's Disease Patient.

BACKGROUND Crohn's disease (CD) is an inflammatory bowel disease affecting approximately 1 in 3000 people in the United States. Since the inflammation of CD is transmural, patients are at risk for fistula and abscess formation. Retroperitoneal abscesses are one type of which physicians must be aware. CASE REPORT We present the case of a 29-year-old woman with CD who complained of right hip and flank pain that began when she was 6-months pregnant. After delivery, she continued to complain of severe right flank pain and was admitted to the hospital 1 month later. CT scan imaging revealed a complicated retroperitoneal and right flank abscess, possibly due to a colonic intramural fistula. She developed severe acute necrotizing soft-tissue infection requiring 13 days of intensive care. She required debridement of the necrotizing infection of the right flank, drainage of the abscess, and washout for intraperitoneal sepsis. The patient tolerated the procedures well and was discharged 1 month later. CONCLUSIONS Given that the clinical manifestation of retroperitoneal fistula with abscess is insidious and its formation is less common than intraperitoneal abscesses, we hope healthcare providers learn from this case to avoid morbidity and mortality. When presented with a pregnant CD patient complaining of nonspecific abdominal symptoms, providers should consider fistulization and/or abscess formation. The option to evaluate pregnant patients using noninvasive methods, such as ultrasound or low-dose CT scan, can decrease radiation exposure to the fetus and prevent delays in diagnosis and treatment.

[A postpartum woman with toxic shock syndrome: group A streptococcal infection, a much feared postpartum complication.] / Een kraamvrouw met toxische-shocksyndroom.

BACKGROUND: The development of toxic shock syndrome (TSS) after an invasive group A streptococcal (GAS) infection in the postpartum period is a much feared complication. The mortality rate of TSS with necrotizing fasciitis is 30 to 50%. CASE DESCRIPTION: We present the case of a woman with atypical pelvic pain which was the first symptom of toxic shock syndrome as a consequence of a GAS infection. Clinical deterioration necessitated a hysterectomy. Also a fasciotomy was performed as consequence of lower extremity compartment syndrome. After this, multiple debridement operations were necessary, followed by split skin grafts. CONCLUSION: This case illustrates the extremely serious complications of GAS infection. In some cases aggressive surgical intervention is necessary, in addition to an optimal antibiotic treatment regime. Ideally, the treatment of a GAS-induced TSS should be managed by a multidisciplinary medical team.

Endometritis: Nontraditional Therapies.

Endometritis is characterized by inflammation of the endometrial lining of the uterus and is a leading cause of subfertility in broodmares. When traditional therapies fall short, nonconventional means can be used either to supplement or in lieu of customary practices to manage endometritis. This article reviews alternative therapies available for use in broodmare practice and provides anecdotal and scientific evidence supporting their use.

Maternal near miss and mortality due to postpartum infection: a cross-sectional analysis from Rwanda.

BACKGROUND: The objective of this study is to evaluate 'near miss' and mortality in women with postpartum infections. METHODS: We performed a retrospective review of all patients referred to the University Teaching Hospital of Kigali (CHUK) between January 2012 and December 2013. We identified 117 patients with postpartum infections. Demographic data, length of admission, location of referral, initial surgery and subsequent treatment modalities including antibiotic administration and secondary surgery were recorded. The primary outcome of interest was a composite of maternal mortality and "near miss" defined as more than one laparotomy with/without hysterectomy and prolonged hospitalization. RESULTS: Diagnoses at CHUK were: pelvic peritonitis (56 %), deep surgical site infection including fasciitis (17 %), and endometritis (15 %). The primary procedures performed prior to transfer were: cesarean section (81 %), septic abortion management (12 %), and vaginal delivery (7 %). Antibiotics were initiated prior to transfer in 66 % of women. Surgery was required in 73 % of patients. Hysterectomies were performed in 22 % of patients. Maternal death occurred in 5 % of the patient population. The primary outcome of severe maternal morbidity and mortality occurred in 90 patients (77 %). CONCLUSION: Peritonitis-primarily as a result of cesarean deliveries-is associated with significant morbidity and mortality in our population.

Puerperal group A streptococcal infection: beyond Semmelweis.

Ignaz Semmelweiss made one of the most important contributions to modern medicine when he instituted handwashing in an obstetric clinic in Austria in 1847, decreasing mortality there from more than 10% to 2%. Unfortunately, puerperal sepsis remains a leading cause of maternal mortality throughout the world. Group A streptococcus (GAS), Streptococcus pyogenes, is an organism associated with high rates of morbidity and mortality from puerperal infections. When associated with sepsis, known as streptococcal toxic shock syndrome, mortality rates approach 30-50%. Group A streptococcus can cause invasive infections in the form of endometritis, necrotizing fasciitis, or streptococcal toxic shock syndrome. The clinical presentation of women with puerperal GAS infections is often atypical with extremes of temperature, unusual and vague pain, and pain in extremities. Toxin production by the organism may allow GAS to spread across tissue planes and cause necrosis while evading containment by the maternal immune system in the form of a discrete abscess. Endometrial aspiration in addition to blood cultures may be a useful rapid diagnostic tool. Imaging may appear normal and should not dissuade the clinician from aggressive management. When suspected, invasive GAS infections should be treated emergently with fluid resuscitation, antibiotic administration, and source control. The optimal antibiotic regimen contains penicillin and clindamycin. Source control may require extensive wound or vulvar debridement, hysterectomy, or a combination of these, which may be life-saving. The benefit of immunoglobulins in management of puerperal GAS infections is unclear.

Puerperal sepsis.

Infections during pregnancy are relatively prevalent, and the majority of cases are managed well in the community. Occasionally, however, infections may be life-threatening. Sepsis may be associated with multiple organ dysfunction and a high mortality. The treatment of sepsis is time critical and requires early fluid resuscitation and antibiotics. Early involvement of other specialties and allied health-care professionals to provide a multidisciplinary approach to patient care is important. Continuous monitoring of maternal vital signs and provision of supportive care for multiple organ dysfunction are best done within the intensive care unit. Despite advances in patient care, the mortality rate associated with maternal sepsis remains high. Health-care services in low-income countries face particular problems that account for an increased incidence of puerperal sepsis and maternal mortality. These include lack of access to health care, septic abortions and a greater incidence of human immunodeficiency virus. The key to management of sepsis is early recognition, aggressive resuscitation, antibiotic administration and source control.

Causes of puerperal and neonatal sepsis in resource-constrained settings and advocacy for an integrated community-based postnatal approach.

BACKGROUND: Puerperal sepsis and neonatal sepsis are important causes of mortality and morbidity in low-income countries. OBJECTIVES: To help improve global guidelines on postpartum care by reviewing existing data on microbiologic causes of sepsis among mothers, newborns, and mother-newborn pairs. SEARCH STRATEGY: An extensive literature review of peer-reviewed publications from resource-constrained settings was conducted using PubMed. SELECTION CRITERIA: Primary research studies containing microbiologic data on puerperal sepsis or combined maternal and neonatal sepsis published since 1980. DATA COLLECTION AND ANALYSIS: Study characteristics and results were analyzed. Data regarding causative microorganisms were tabulated and discussed in the main text. MAIN RESULTS: Diagnostic evaluation of microorganisms causing puerperal sepsis was difficult, with few studies linking microorganisms causing infection in individual mother-newborn pairs. The most frequent microorganisms associated with puerperal sepsis were Neisseria gonorrhoeae and Chlamydia trachomatis. The most frequent microorganisms associated with neonatal sepsis were Escherichia coli, Staphylococcus aureus, and Klebsiella species. CONCLUSIONS: Management tools for community-based care of mothers with puerperal sepsis-including early detection, initiation of broad-spectrum antibiotic treatment, and timely referral-should be added to those currently in use for neonatal sepsis. Further research is required to address acceptability, feasibility, and impact of community-based presumptive treatment.
