Group A Streptococcus Causing Necrotizing Fasciitis and Toxic Shock Syndrome After Medical Termination of Pregnancy

How could we suspect life-threatening perinatal group A streptococcal infection?

AIM

Perinatal group A streptococcal infection is a rare but life-threatening condition. Few reports have focused on its clinical characteristics and how to prevent deterioration. We report our experience with two antenatal fatal cases and reviewed 96 cases in the literature to assess the clinical characteristics of group A streptococcal infection.

METHODS

English-language clinical reports of antenatal and postnatal group A streptococcal infection in 1974-2019 were retrieved and examined. Relationships between clinical characteristics and maternal outcomes were assessed.

RESULTS

Univariate analysis revealed that antenatal group A streptococcal infection was significantly associated with an age of ≤19 or ≥ 35 years, cesarean section, sore throat as an initial symptom, positive throat culture, maternal death and fetal death. Multivariate analysis revealed that antenatal onset (odds ratio = 7.922, 95% confidence interval = 1.297-48.374; P = 0.025) and a quick sepsis-related organ-failure assessment score (qSOFA; low blood pressure, high respiratory rate or altered mental status) of ≥2 (odds ratio = 6.166, 95% confidence interval = 1.066-35.670; P = 0.042) were significantly related to maternal death.

CONCLUSION

Per our findings, antenatal group A streptococcal infection was significantly associated with maternal and fetal death. Further, the antenatal infection was revealed as a more critical risk factor. We suggest that the presence of any sign related to the qSOFA is a potential clue suspecting perinatal group A streptococcal infection in primary obstetric facilities.

Necrotizing Soft Tissue Infections in the Vasculopathic Patient: Review of Literature

Background:

Necrotizing soft tissue infection is a surgical emergency associated with high mortality. Its presence in patients with risk factors for peripheral arterial disease such as diabetes mellitus is consistently associated with significantly poorer outcomes. Though it has been over a century since it was initially described in the literature, mortality rates remain high and treatment regimens are not standardized.

Materials and methods:

PubMed and Cochrane databases were searched for articles pertaining to necrotizing soft tissue infections. Articles were screened for relevance with the intent to compare outcomes in prospective studies of patients with diabetes mellitus or peripheral arterial disease. Patient demographics, clinical findings, mortality, rates of amputation, and morbidity were intended to be compared.

Results:

857 articles were identified, 165 duplicates were removed, and 6 prospective trials were identified for inclusion. Due to significant paucity of data, patient heterogeneity, and lack of standardization for surgical management, a descriptive review of the literature in relation to necrotizing soft tissue infections was pursued, with a focus on high-risk patients with peripheral arterial disease or diabetes mellitus.

Conclusions:

Early aggressive surgical intervention or major amputation may reduce mortality at the cost of increased disability and poorer quality of life in the long term, and may be appropriate in vasculopaths with poorly controlled diabetes and rapidly progressive fulminant infection. However, there is a deficiency in high-level evidence supporting surgical decision-making in this setting, with no standardized protocols for amputation. Future research will be needed to clarify the patient population who would benefit from radical amputation versus intention for limb salvage.

Group A Streptococcus Septic Shock after Surgical Abortion: A Case Report and Review of the Literature

Group A Streptococcus (GAS) causing puerperal sepsis is a leading cause of maternal mortality worldwide. Although rare, GAS infection is a relatively significant public health concern because of its propensity to evolve rapidly into septic shock, streptococcal toxic shock syndrome, and death. We report the case of a 27-year-old patient who presented with GAS septic shock after undergoing a surgical termination of pregnancy and was treated successfully and recovered without sequelae. GAS septic shock should always be included in the differential diagnosis of any patient who develops sepsis after a surgical abortion. Patients with GAS septic shock have a rapid clinical decline and need aggressive fluid management, early initiation of broad-spectrum antibiotics, and rapid surgical intervention.

[Complications of termination of pregnancy]

The legalization of abortion in France allowed to disappear almost maternal deaths caused by induced abortions. Nevertheless, the practice of abortion in a medical framework is encumbered with a number of immediate complications. Similarly, the late consequences of the practice of surgical abortion have generated an abundant literature, which it is important to analyse, both to meet the legitimate concerns of patients as to prevent any spread of false ideas under the influence of movements opposed to abortion.

Medical Abortion

OBJECTIVE

This guideline reviews the evidence relating to the provision of first-trimester medical induced abortion, including patient eligibility, counselling, and consent; evidence-based regimens; and special considerations for clinicians providing medical abortion care.

INTENDED USERS

Gynaecologists, family physicians, registered nurses, midwives, residents, and other healthcare providers who currently or intend to provide pregnancy options counselling, medical abortion care, or family planning services.

TARGET POPULATION

Women with an unintended first trimester pregnancy.

EVIDENCE

Published literature was retrieved through searches of PubMed, MEDLINE, and Cochrane Library between July 2015 and November 2015 using appropriately controlled vocabulary (MeSH search terms: Induced Abortion, Medical Abortion, Mifepristone, Misoprostol, Methotrexate). Results were restricted to systematic reviews, randomized controlled trials, clinical trials, and observational studies published from June 1986 to November 2015 in English. Additionally, existing guidelines from other countries were consulted for review. A grey literature search was not required.

VALUES

The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force for Preventive Medicine rating scale (Table 1).

BENEFITS, HARMS AND/OR COSTS

Medical abortion is safe and effective. Complications from medical abortion are rare. Access and costs will be dependent on provincial and territorial funding for combination mifepristone/misoprostol and provider availability.

Disseminated Intravascular Coagulation Syndromes in Obstetrics

Disseminated intravascular coagulation (DIC) is a syndrome that can be initiated by a myriad of medical, surgical, and obstetric disorders. Also known as consumptive coagulopathy, DIC is a common contributor to maternal morbidity and mortality and is associated with up to 25% of maternal deaths. The etiopathogenesis of DIC is complex and currently thought to be initiated by tissue factor or thromboplastin, which is released from trophoblastic or fetal tissue, or maternal decidua or endothelium. Tissue factor activates the coagulation sequence to cause fibrin clotting and its dissolution by the fibrinolysin system. The result of this process can range from mild, clinically insignificant laboratory derangements to marked coagulopathy with bleeding at sites of minimal trauma. Although clinical recognition varies by disease severity, several organizations have attempted to standardize the diagnosis through development of scoring systems. Several important--albeit not necessarily common--obstetric disorders associated with DIC include placental abruption, amniotic fluid embolism, sepsis syndrome, and acute fatty liver of pregnancy. More common disorders include severe preeclampsia, hemolysis, elevated liver enzymes, and low platelet count syndrome, and massive obstetric hemorrhage. Importantly, many of these disorders either cause or are associated with substantive obstetric hemorrhage. Treatment of DIC is centered on two principles. The first is identification and treatment of the underlying disorder. Because many women with consumptive coagulopathy also have massive hemorrhage, the second tenet of treatment is that obstetric complications such as uterine atony or lacerations must be controlled simultaneously with prompt blood and component replacement for a salutary outcome.

A case of toxic shock due to clandestine abortion by misoprostol self-administration

Maternal mortality and morbidity are the leading causes of death and illness, respectively, among women of reproductive age in many countries throughout the world. Of all maternal deaths, those related to unsafe abortions are the most widely underestimated, but they are also the most largely preventable. Medical abortion is a safe and reliable method for termination of a pregnancy in early gestation, although it is important to be aware of signs and symptoms of severe infection and toxic shock syndrome after the medical termination of pregnancy; case studies in literature are rarely fatal events. We report the first case of septic shock syndrome following a clandestine pregnancy termination with a misoprostol-only regimen (12 tablets 200 μg each). Autopsy findings and histopathological examination proved that the woman died from septic shock. This case suggests to improve the forensic investigations in case of unsafe, often clandestine, abortion is suspected.

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.

Group A Streptococcus endometritis following medical abortion

Medical abortion is not recognized as a high-risk factor for invasive pelvic infection. Here, we report two cases of group A Streptococcus (GAS; Streptococcus pyogenes) endometritis following medical abortions with a protocol of oral mifepristone and misoprostol.
