Streptococcus G leading to septic abortion and multiple organ failure.

The authors report a patient admitted at 12 weeks of pregnancy with an acute infectious syndrome, leading to abortion, sepsis, and multiple organ failure. Admission to intensive care unit (ICU) was needed after curettage for incomplete abortion complicated by uterine atony, hemorrhage, and septic shock. The patient had multiple organ failure and required non-invasive ventilation. Hemoculture showed streptococcus G bacteremia. She had no evidence of concurrent infection, mainly genital or urinary, except amygdalitis few days before. Hematogenous spread to the gestational sac could have possibly been the cause of her sepsis. Streptococcus G infection during pregnancy can lead to severe consequences.

Aborto séptico por Clostridium perfringens complicado con shock séptico / Septic abortion due to Clostridium perfringens complicated with septic shock

ANTECEDENTES: La sepsis por Clostridios es una entidad poco frecuente que conlleva una mortalidad del 8090% a pesar del tratamiento antibiótico y quirúrgico. A pesar de que la mayoría de los casos de septicemia secundaria a Clostridios se originan en el aparato genital femenino tras un aborto séptico, solo un pequeño porcentaje de abortos sépticos (1%) se siguen de septicemia. CASO CLÍNICO: Gestante de 15 semanas que acude a urgencias por rotura prematura de membranas pretérmino. Ante el deseo de la paciente se mantiene actitud conservadora con antibioterapia iv, produciéndose a las pocas horas el aborto de forma espontánea junto con aparición de signos de infección. Rápidamente la paciente evoluciona a sepsis grave, y ante la sospecha de aborto séptico se efectúa histerectomía. Tras la intervención ingresa en situación de shock séptico con insuficiencia renal, hepática y respiratoria. Durante el ingreso se confirma Clostridium perfringens como agente responsable del proceso séptico. Finalmente la paciente es dada de alta definitiva tras seis meses, una vez resueltas las alteraciones derivadas del proceso séptico.

BACKGROUND: Clostridial sepsis is a rare condition which carries a mortality of 80-90% despite antibiotic and surgical treatment. Although most cases of septicemia due to Clostridium are originated in female genital tract after septic abortion, only a small percentage of septic abortions (1%) are followed by septicemia. CLINICAL CASE: Our case is about a 15 weeks pregnant woman attended the emergency room for preterm premature rupture of membranes. Due to the desire of the patient we proceed conservative treatment with antibiotics iv, in the following few hours the abortion develops spontaneously along with signs of infection. Rapidly the patient progresses into a severe sepsis, due to suspected septic abortion, the patient is intervened urgently by hysterectomy. After the intervention she enters into septic shock state with respiratory, kidney and liver failure. During the admission Clostridium perfringens is confirmed as a causative agent for septic process. Finally the patient is discharge after six months once resolved all complications arising from septic process.

Treating spontaneous and induced septic abortions.

Worldwide, abortion accounts for approximately 14% of pregnancy-related deaths, and septic abortion is a major cause of the deaths from abortion. Today, septic abortion is an uncommon event in the United States. The most critical treatment of septic abortion remains the prompt removal of infected tissue. Antibiotic administration and fluid resuscitation provide necessary secondary levels of treatment. Most young physicians have never treated septic abortion. Many obstetrician-gynecologists experience, or plan to experience, global health activities and will likely care for women with septic abortion. Thus, updated knowledge of the pathophysiology, clinical presentation, microbes, and proper treatment is needed to optimally treat this emergency condition when it exists. The pathophysiology of septic abortion involves infection of the placenta, especially the maternal villous space that leads to a high frequency of bacteremia. Symptoms and signs range from mild to severe. The microbes involved are usually common vaginal bacteria, including anaerobes, but occasionally potentially very serious and lethal infection is caused by bacteria that produce toxins. The primary treatment is early curettage to remove infected and devitalized tissue even in the face of continued fetal heart tones. Important secondary treatments are the administration of fluids and antibiotics. Updated references of sepsis and septic shock are reviewed.

Disseminated intravascular coagulation in pregnancy: insights in pathophysiology, diagnosis and management.

Disseminated intravascular coagulation (DIC) is a life-threatening situation that can arise from a variety of obstetrical and nonobstetrical causes. Obstetrical DIC has been associated with a series of pregnancy complications including the following: (1) acute peripartum hemorrhage (uterine atony, cervical and vaginal lacerations, and uterine rupture); (2) placental abruption; (3) preeclampsia/eclampsia/hemolysis, elevated liver enzymes, and low platelet count syndrome; (4) retained stillbirth; (5) septic abortion and intrauterine infection; (6) amniotic fluid embolism; and (7) acute fatty liver of pregnancy. Prompt diagnosis and understanding of the underlying mechanisms of disease leading to this complication in essential for a favorable outcome. In recent years, novel diagnostic scores and treatment modalities along with bedside point-of-care tests were developed and may assist the clinician in the diagnosis and management of DIC. Team work and prompt treatment are essential for the successful management of patients with DIC.

Inflammatory agents involved in septic miscarriage.

Even though the understanding of the cause of early pregnancy loss due to chromosomal abnormalities has improved, there is a dearth of knowledge of the causes of loss in euploid conceptuses. Maternal infections are a cause of abort in humans, but the mechanisms are not clear, so we have developed a murine model to study the mechanism of septic abortion by inducing embryonic resorption (ER) with lipopolysaccharide (LPS). We demonstrated that augmented production of nitric oxide (NO) and prostaglandins (PG) is involved in ER, and that inhibitors of their synthesis could prevent ER. Also, we observed an increase in the oxidative damage, evidenced by nitration of tyrosine proteins, due to the peroxynitrite anion. Since an association between chronic marijuana smoking and early miscarriage has been shown in women, we studied the participation of anandamide (AEA), the principal endocannabinoid, on the mechanism of action of LPS. We showed that LPS-induced NO synthesis and tissue damage were mediated by AEA, and that this endotoxin inhibited AEA degradation and increased its synthesis. These results suggest that several inflammatory molecules participate in the mechanism of early pregnancy loss and that their modulation could be useful tools to prevent it.

Women with septic abortion: who, how and why? A prospective study from tertiary care hospital in India.

A prospective descriptive interview based hospital study was carried on 47 women admitted with septic abortion to evaluate their psychosocial, demographic and clinical profile These women were predominantly parous (75%), hindus (60%), between 20-30 years of age (60%) and mostly married (91.4%) house wives (63.8%). More than 90% already had one or more male child. The contraceptive use was dismally low (23.4%). Their knowledge about legalisation, place and persons authorized to conduct abortions was very less, however large majority (87%) underwent abortions within 3 months of pregnancy. Large family, poverty and spacing were the main reasons cited for abortions. Abdominal pain, fever, genital bleeding, diarhoea and abdominal distension were presenting clinical features in order of frequency. Advanced sepsis and associated medical and surgical complications were present in more than half the patients and 6% succumbed to these problems. The current experience was an eye opener for most of them and changed their future attitude. Hence education, economic prosperity, easy access to reproductive health facilities and institutional management of sepsis is the key to make abortions safe.

Pathophysiology of mifepristone-induced septic shock due to Clostridium sordellii.

OBJECTIVE: To explain the role of mifepristone in medical abortions that results in fulminant and lethal septic shock due to Clostridium sordellii. DATA SOURCES: MEDLINE, PubMed, and Google Scholar databases were searched (1984-March 2005). Key search terms were mifepristone, RU38486, RU486, Mifeprex, medical abortion, septic shock, innate immune system, cytokines, and Clostridium sordellii. STUDY SELECTION AND DATA EXTRACTION: All articles identified from the data sources were evaluated and all information deemed relevant was included for the information related to the development of the understanding of the pathophysiology of mifepristone-induced septic shock due to C. sordellii. DATA SYNTHESIS: The mechanisms of action of mifepristone were incorporated into the pathophysiology of septic shock due to C. sordellii. Mifepristone, by blocking both progesterone and glucocorticoid receptors, interferes with the controlled release and functioning of cortisol and cytokines. Failure of physiologically controlled cortisol and cytokine responses results in an impaired innate immune system that results in disintegration of the body's defense system necessary to prevent the endometrial spread of C. sordellii infection. The abnormal cortisol and cytokine responses due to mifepristone coupled to the release of potent exotoxins and an endotoxin from C. sordellii are the major contributors to the rapid development of lethal septic shock. CONCLUSIONS: Theoretically, it appears that the mechanisms of mifepristone action favor the development of infection that leads to septic shock and intensifies the actions of multiple inflammatory cytokines, resulting in fulminant, lethal septic shock.

The clinical course of patients with septic abortion admitted to an intensive care unit.

OBJECTIVE: The purpose of this study was to describe the clinical course, complications, and outcome of patients with septic abortion admitted to the intensive care unit (ICU). DESIGN, SETTING, AND PATIENTS: In this retrospective study, the records of 63 patients with septic abortion admitted to the ICU of a university hospital in Argentina between 1985 and 1995 were reviewed. RESULTS: The mean age of the patients was 28.5 years, and 33% had had previous abortions. The mean gestational age was 10.5 weeks. The first ICU day Acute Physiology and Chronic Health Evaluation (APACHE) II mean score was 13.9. Acute renal failure developed in 73% (46 of 63) of the patients, disseminated intravascular coagulation (DIC) in 31% (15 of 49), and septic shock in 32% (20 of 63). Blood cultures were positive in 24% (15 of 62). Twelve patients died (19%). Eight of the deaths occurred during the first 48 h of the ICU admission. Compared with survivors, non-survivors had higher median number of organ failures (1.0 vs 4.0, p<0.0001), mean first ICU day SOFA scores (6.6 vs 10.0, p=0.0059), and mean APACHE II scores (12.7 vs 20.2, p=0.0003), and were more likely to have septic shock (18 vs 92%, p<0.0001), and receive dopamine (37 vs 83%, p=0.0040), mechanical ventilation (8 vs 83%, p<0.0001), and pulmonary artery catheter (8 vs 41%, p=0.0026). CONCLUSIONS: Although it is an avoidable complication, septic abortion requiring admission to the ICU is associated with high morbidity and mortality.

Fatal clostridial sepsis after spontaneous abortion.

BACKGROUND: Although obstetric mortality due to complications of Clostridium perfringens infection is rare at present, we report a case of fatal clostridial sepsis secondary to a septic spontaneous abortion. CASE: A woman at 6-8 weeks' gestation presented with vaginal bleeding and abdominal pain. Although afebrile, the patient was hypotensive, tachycardic, and tachypneic. Physical examination was remarkable for a 10-weeks'-gestation-size uterus, mild pelvic tenderness, a closed cervix without signs of trauma, and moderate vaginal bleeding. Laboratory studies were consistent with infection, hemolysis, and coagulopathy. Sonography demonstrated echolucencies consistent with gas formation in the endometrial cavity. Despite fluid resuscitation, transfusions, antibiotic therapy, and a dilation and curettage, persistent vaginal bleeding required an emergency hysterectomy. Hypotension ensued, and despite aggressive resuscitation attempts, the patient died. CONCLUSION: Rare cases of fatal sepsis secondary to pelvic infection with Clostridium perfringens continue to occur. Hemolysis, anuria, coagulopathy, and characteristic sonographic findings should heighten suspicion of this potentially fatal infection.

Application of multiplex polymerase chain reaction for rapid identification of Campylobacter jejuni and C coli associated with reproductive failure.

OBJECTIVE: To evaluate a multiplex polymerase chain reaction (PCR) to distinguish Campylobacter jejuni from C coli as causes of reproductive failure. PROCEDURE: Review of clinical cases of reproductive failure attributed to C jejuni or C coli. RESULTS: A case of swine abortion was attributable to infection with C coli. The porcine abortion isolates were verified as C coli by restriction fragment length polymorphism and multiplex PCR. Cases of endometritis in a fox and in mink caused by C jejuni were reviewed, and isolates were confirmed as C jejuni by results of the multiplex PCR. CONCLUSION: Multiplex PCR was useful in identifying C coli and C jejuni recovered from atypical cases of reproductive failure. Multiplex PCR in conjunction with conventional assays may be useful for verifying other unusual instances of campylobacteriosis.

Glomerular hemodynamics during abortion induced by RU 486 and sepsis in rats.

1. Acute renal failure is a very common consequence of septic abortion. Whole kidney and glomerular hemodynamics were evaluated in virgin (V), pregnant (PREG) and aborted (ABOR) euvolemic Munich-Wistar rats before and after E. coli (0111-B4) endotoxin (LPS) infusion in order to evaluate the effect of septic abortion on the renal microcirculation. 2. Abortion induced by RU 486 blunted the increase in glomerular filtration rate (GFR) induced by normal pregnancy (0.86 +/- 0.03 vs 0.63 +/- 0.07 ml/min, P < 0.05). In virgin rats, RU 486 did not modify the parameters of renal function. Significant alterations occurred in whole kidney and single nephron function. However, the changes in whole kidney function in the ABOR group were significantly higher than those observed for the V group (reductions in GFR were 42% in V and 80% in ABOR, RPF decreased 34% in V and 76% in ABOR, TRVR increased 82% in V and 400% in ABOR). 3. Mean single nephron glomerular filtration rate (SNGFR) was reduced in all groups after LPS (44% in V, 43% in V+RU, 55% in PREG, 60% in ABOR), due to significant decreases in glomerular plasma flow rate, QA (42% in V, 55% in V+RU, 53% in PREG, 57% in ABOR) and in glomerular ultrafiltration coefficient, Kf (46% in V, 47% in V+RU, 45% in PREG, 67% in ABOR). 4. These data show that LPS induced significant alterations in renal function in all groups. However, aborted rats were more sensitive to the effects of LPS than V rats. These results indicate that abortion may potentiate the effects of endotoxemia on renal function elevating the extent of acute renal failure and thus the mortality rate.

The septic shock has a low frequency in the gynecologic-obstetric patients, nevertheless several obstetric conditions like: septic abortion, chorioamnionitis or puerperal infections can be complicated with this syndrome. The infections cause near 20% of the maternal deaths. Because the high morbidity and mortality of the patients with septic shock is necessary to have an actual knowledge of its pathogenesis and treatment. Any person can be infected but only few of them will develop a septic shock, the response of the host to the microorganisms is the critical point for the develop of this syndrome. Many studies had showed the importance of the bacterial endotoxin and the tumoral necrosis factor as mediators of septic shock. The treatment include: control of the infectious process, restoration of tissue perfusion pressure, restoration of blood volume, use of inotropic agents and general support measures. The role of monoclonal antibodies against endotoxin in the management of Gram-negative sepsis is still ignored, but there are several studies that support its use.

El choque séptico (CHS) es un evento poco frecuente en las pacientes gineco-obstétricas, no obstante diversas condiciones como el aborto séptico, las corioamnioitis, y las infecciones puerperales pueden complicarse con este síndrome. Los problemas infecciosos representan cerca de 20 por ciento de las muertes maternas. Debido a la alta morbilidad que el CHS condiciona, es necesario tener un conocimiento actualizado del mismo. No obstante que cualquier individuo puede padecer una infección, la respuesta del hospedero a los microporganismos invasores es el punto crítico para el desarrollo del CHS. Múltiples evidencias han mostrado la importancia de las endotoxinas bacterianas y del factor de necrosis tumoral en la patogénesis de este síndrome. El manejo incluye: control de proceso infecciosos, mantenimiento de un aporte adecuado de 02 a los tejidos, uso de agentes inotrópicos y medidas de soporte general. El uso de anticuerpos monoclonales contra endotoxinas es la perspectiva de tratamiento más promisoria, aunque hasta el momento acutal no ha sido demostrada una eficacia real

El aborto séptico es un proceso infeccioso cuyo origen más frecuente es la realización de procedimientos abortivos de tipo ilegal. Las cifras reales de este problema en nuestro país no son bien conocidas, no obstante está bien definida su alta morbilidad y mortalidad. La amplia irrigación sanguínea y linffática de la placenta y del endometrio facilita la entrad de microorganismos durante el procedimiento abortivo, con desarrollo de bacteremia, diseminación de la infección y en algunas pacientes evolución al choque séptico. Múltiples evidencias han mostrado la importancia de las endotoxinas bacterianas y del factor de necrosis tumoral en la patogénesis del choque séptico. El manejo de esta patología incluye: control del poceso infeccioso, mantenimiento de un aporte adecuado de oxígeno a los tejidos, uso de agentes inotrópicos y medidas de soporte general. El uso de anticuerpos monoclonales contra endotoxinas es la perspectiva de tratamiento más promisoria de este síndrome, aunque hasta el momento actual no ha sido claramente demostrada su utilidad
