RESUMO

INTRODUCTION: Purulent pericarditis secondary to esophago-pericardial fistula is a serious complication that has been previously reported in patients with esophageal cancer treated with radio/chemotherapy and esophageal stenting. However, the presence of esophago-pericardial fistula as the first manifestation of advanced carcinoma of the esophagus is exceedingly infrequent. We report the case of a 61-year-old male who presented with sepsis, cardiac tamponade and septic shock who was found to have an esophago-pericardial fistula secondary to squamous carcinoma of the esophagus. Emergency pericardiocentesis was performed with subsequent hemodynamic improvement. The drained pericardial fluid was purulent in nature and cultures were positive for Streptococcus anginosus. A CT scan followed by upper gastrointestinal endoscopy with tissue biopsy confirmed the diagnosis of squamous cell carcinoma of the esophagus. A self-expanding covered stent was endoscopically placed to exclude the fistula and restore the esophageal lumen. In this report, we discuss some aspects related to the diagnosis and management of this serious clinical entity.

RESUMO

 Streptococcus gallolyticus subspecies pasteurianus is a subtype of Streptococcus bovis (S. bovis) that has become increasingly recognized as a sepsis-causing pathogen in neonates. It is well documented that S. bovis species have a predilection to both cardiac and gastrointestinal tissue, and in adult populations, isolating these organisms in the bloodstream often triggers further evaluation for co-morbid complications such as colon cancer or endocarditis. However, no such guidance currently exists in neonatal literature. We present a case of a preterm infant with S. gallolyticus subsp. pasteurianus bacteremia presenting as necrotizing enterocolitis (NEC) not previously described in the literature. Furthermore, through a complete diagnostic evaluation, including an echocardiogram, our patient was found to have the rare complication of endocarditis.

RESUMO

BACKGROUND: Hearing loss is a common sequala of Streptococcus suis (S. suis) meningitis, but few have addressed cochlear implantation (CI) candidates with S. suis meningitis. OBJECTIVES: To assess the clinical characteristics and CI postoperative outcomes in S. suis meningitis patients. MATERIAL AND METHODS: Eight S. suis meningitis patients underwent CI at Sun Yat-sen Memorial Hospital between 2020 and 2023. Control groups included (1) non-Suis meningitis patients (n = 12) and (2) non-meningitis patients (n = 35). Electrode impedances and neural response telemetry (NRT) thresholds were recorded at one month after surgery. The auditory performance-II (CAP) and speech intelligibility rating (SIR) were recorded at the last visit. RESULTS: CAP scores of S. suis meningitis patients were significantly lower than those of non-Suis meningitis and non-meningitis patients (p = .019; p<.001). And NRT thresholds of S. suis meningitis patients were higher than those of non-Suis meningitis and non-meningitis patients (p = .006; p = .027). CONCLUSIONS AND SIGNIFICANCE: It is recommended for S. suis meningitis CI candidates to undergo CI promptly after controlling infection, preferably within four to six weeks. CI users with S. suis meningitis tend to exhibit suboptimal hearing rehabilitation outcomes, possibly associated with the more severe damage on spiral ganglion cells after S. suis meningitis.

RESUMO

BACKGROUND: Acute post-streptococcal glomerulonephritis (APSGN) is the most common cause of acute nephritis in children globally and, in some cases, may be associated with progressive kidney injury and failure, cumulating in the need for long-term dialysis and/or kidney transplantation. METHODS: Our retrospective study describes the occurrence of APSGN among children (< 14 years) admitted to a tertiary children's hospital in Cape Town, South Africa, from January 2015 to December 2020. RESULTS: Of 161 children who presented with acute nephritis (haematuria, oedema, oliguria, and hypertension), 100 met the inclusion criteria. Demographic, clinical features, laboratory findings, management, and outcome data were collected. APSGN was defined by the clinical presentation of at least two clinical signs of acute nephritis, and low serum complement 3 (C3) level or evidence of a recent streptococcal infection. Most cases of APSGN were associated with streptococcal skin infections: 55/100 (55%); 10/100 (10%) children presented with hypertensive seizures; C3 levels were low in 86/92 (93.5%) children; 94/94 (100%) children had elevated anti-deoxyribonuclease-B (anti-DNase-B) levels; and 80/94 (85%) also had elevated anti-streptolysin O titre (ASOT) at presentation. Eleven (11%) children had a percutaneous kidney biopsy; 4/11 (36%) showed histological features of post-infectious nephritis, and 7/11(64%) also had crescentic glomerulonephritis with immune complex deposits. Sixty-two (62%) children confirmed recovered, and five (5%) progressed to kidney failure, but 29 presumed recovered as they did not return for follow-up to our institution. CONCLUSIONS: Childhood APSGN remains an important health problem in South Africa (SA) with favourable outcomes in most, apart from those with crescentic glomerulonephritis who progressed to kidney failure.

RESUMO

OBJECTIVES: To describe the clinical features, history and association with intestinal disease in central nervous system (CNS) S. bovis infections. METHODS: Four cases of S. bovis CNS infections from our institution are presented. Additionally a systematic literature review of articles published between 1975 and 2021 in PubMed/MEDLINE was conducted. RESULTS: 52 studies with 65 cases were found; five were excluded because of incomplete data. In total 64 cases were analyzed including our four cases: 55 with meningitis and 9 with intracranial focal infections. Both infections were frequently associated with underlying conditions (70.3%) such as immunosuppression (32.8%) or cancer (10.9%). In 23 cases a biotype was identified, with biotype II being the most frequent (69.6%) and S. pasteurianus the most common within this subgroup. Intestinal diseases were found in 60.9% of cases, most commonly neoplasms (41.0%) and Strongyloides infestation (30.8%). Overall mortality was 17.1%, with a higher rate in focal infection (44.4% vs 12.7%; p=0.001). CONCLUSIONS: CNS infections due to S. bovis are infrequent and the most common clinical form is meningitis. Compared with focal infections, meningitis had a more acute course, was less associated with endocarditis and had a lower mortality. Immunosuppression and intestinal disease were frequent in both infections.

RESUMO

Streptococcus salivarius is part of the normal oral cavity and gastrointestinal tract microflora and an unusual cause of acute bacterial meningitis. We herein report an 81-year-old man with S. salivarius meningitis, which led to a diagnosis of early esophageal cancer and early gastric cancer. S. salivarius infection may occur through the gastrointestinal mucosa when it is disrupted in association with early gastrointestinal cancer. To our knowledge, this is the first report describing S. salivarius meningitis associated with multiple early gastrointestinal cancers in the absence of other sources of infection.

RESUMO

Neonatal necrotising fasciitis secondary to Streptococcus agalactiae, also known as Group B Streptococcus (GBS), is a rare, life-threatening entity with approximately 40 cases reported in the literature.1 GBS soft tissue infection in infancy most commonly affects the face, likely originating from the colonised oral cavity.2 In cases unresponsive to medical management alone, early surgical debridement can be life-saving. We present a case of faciocervical GBS necrotising fasciitis in a male neonate requiring multiple surgical debridements. The resultant soft tissue defect healed with topical negative pressure therapy and eventual placement of a double-layer dermal substitute. Due to his prematurity, the patient was not skin grafted to limit donor site morbidity. After recovering from his life-threatening infection, the patient had intensive scar therapy leading to a favourable cosmetic result with no evidence of function-limiting contracture. Our report draws focus to the need for a multidisciplinary approach incorporating therapy-led scar management early in the postsurgical recovery plan.

RESUMO

Neonatal osteomyelitis (OM), although exceptionally rare, has been linked to detrimental sequel, as diagnosis in the early stages is challenging and any delay in treatment can lead to disturbance in skeletal growth. In pediatric OM the most commonly grown bacteria is Staphylococcus aureus followed by group A Streptococcus (GAS). Notwithstanding, sepsis-induced coagulopathy is a well-known entity in children and adults, still sepsis-associated thrombosis is sparsely observed. we present a case of a newborn with GAS associated OM and thrombosis. A term neonate on the 11th day of life was referred to our NICU due to right (R) lower limb edema, cyanosis and core temperature up to 39 °C. Late onset sepsis was suspected and started on vancomycin and amikacin. A colour Doppler scan showed thrombosis of the R common femoral vein. The neonate started on iv unfractionated heparin. Ampicillin was added given positive for GAS blood culture. An MRI on the 5th day of admission, showed evidence of thrombosis resolution. On the 14th day of admission, a bone Tc99 scan showed evidence of OM of R femur. Antibiotic treatment switched to amoxicillin per os. The management was restricted to anticoagulant therapy with low molecular weight heparin for 3 months and antibiotic therapy for 6 months without surgery intervention and the patient recovered and discharged at 42 days of age. Early diagnosis and treatment of neonatal osteomyelitis can prevent bone destruction. Sepsis-associated thrombosis is barely observed during osteomyelitis, yet it should be considered as an emerged case requiring prompt treatment.

RESUMO

RATIONALE: Streptococcal toxic shock syndrome (STSS) rapidly leads to refractory shock and multiple organ failure. The mortality rate among patients with STSS is 40%; however, most deaths occur within a few days of onset. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) may help avoid acute death in adult patients with STSS. However, the effectiveness of VA-ECMO is unclear. In this study, we report a case of group B STSS, which was successfully treated with VA-ECMO despite cardiopulmonary arrest (CPA) owing to rapidly progressive refractory shock. PATIENT CONCERNS: A 60-year-old woman was hospitalized because of diarrhea and electrolyte abnormalities owing to chemoradiation therapy for rectal cancer. A sudden deterioration of her condition led to CPA. Conventional cardiopulmonary resuscitation was immediately performed but was ineffective. Therefore, VA-ECMO was initiated. Contrast-enhanced computed tomography revealed duodenal perforation. Hence, septic shock owing to peritonitis was diagnosed, and emergency surgery was performed under VA-ECMO. However, the patient had progressive multiple organ failure and required organ support therapy in the intensive care unit (ICU). DIAGNOSES: On day 2 in the ICU, blood and ascites fluid culture tests revealed beta-hemolytic streptococci, and the patient was finally diagnosed as having STSS caused by Streptococcus agalactiae. INTERVENTIONS: Clindamycin was added to meropenem, vancomycin, and micafungin, which had been administered since the sudden deterioration. In addition, VA-ECMO, mechanical ventilation, blood purification therapy, and treatment for disseminated intravascular coagulation were continued. OUTCOMES: Thereafter, hemodynamics improved rapidly, and the patient was weaned off VA-ECMO on day 5 of ICU admission. She was transferred to a general ward on day 22 in the ICU. LESSONS: In patients with fatal STSS and rapid progressive refractory shock or CPA, VA-ECMO may help to avoid acute death and improve prognosis by ameliorating tissue oxygenation and providing extra time to treat invasive streptococcal infection.

RESUMO

We report a case of Streptococcus mitis endocarditis associated with early gastric carcinoma. A 71-year-old man who had been diagnosed with aortic regurgitation (AR) two years previously was referred for valve surgery and evaluation of elevated inflammatory markers. Four months previously, atrophic gastritis, early gastric adenocarcinoma, and colon polyp had been identified in the patient during endoscopy. However, Helicobacter pylori testing was negative. On admission, he had no dental diseases or recent oral procedures. Echocardiography demonstrated severe AR and mobile vegetation on the aortic valve. Magnetic resonance imaging revealed cerebral embolism and spondylodiscitis. Blood cultures grew Streptococcus mitis. At surgery, destruction of the left cusp with vegetation and a perforation of the non-coronary cusp were found; in addition, aortic valve replacement was performed. Although the association between Streptococcus bovis bacteremia and colon neoplasm is well recognized, the association between Streptococcus mitis endocarditis and gastrointestinal carcinoma should also be kept in mind.

RESUMO

BACKGROUND AND STUDY AIMS: Colorectal cancer (CRC) is the second most common cancer in Malaysia and mostly detected at advanced stages due to lack of awareness of CRC symptoms and signs. CRC pathogenesis is multifactorial, and there is ambiguous evidence on association of Streptococcus gallolyticus infection with CRC that needs further attention. Thus, a case-control study was conducted to determine whether S. gallolyticus infection is a predictor for CRC occurrence among patients attending Sultan Ahmad Shah Medical Centre@IIUM (SASMEC@IIUM). PATIENTS AND METHODS: A total of 33 stool samples from patients diagnosed with CRC and 80 from patients without CRC attending surgical clinic of SASMEC@IIUM were collected and analyzed with iFOBT test and PCR assay to detect S. gallolyticus. RESULTS: In this study, the proportion of S. gallolyticus infection was higher among patients with CRC (48.5%) compared with the control group (20%). Univariate analysis shows that occult blood in stool, S. gallolyticus infection and family history were significantly associated with the development of CRC (P < 0.05). Using the multivariate logistic regression model, positive stool PCR for S. gallolyticus had the lowest relative standard error and almost five times the odds of developing CRC after adjusting other factors (adjusted odds ratio = 4.7, 95% confidence interval = 1.7-12.6, relative standard error = 59.6%). CONCLUSION: This finding suggests that S. gallolyticus infection was the strongest predictor of CRC's development in our study and potentially serves as a predictive marker for early detection of disease progression.

RESUMO

Whether cirrhotic patients with Streptococcus bovis bacteremia have an increased risk of colorectal neoplasm is uncertain. A multicentric retrospective cohort study was conducted investigating associations between S. bovis biotype and species, cirrhosis, and colorectal neoplasm. Out of 779 patients with S. bovis bacteremia, 69 (8.7%) had cirrhosis. No differences were found in the prevalence of colorectal neoplasm between cirrhotic and non-cirrhotic patients undergoing colonoscopy. Among cirrhotic patients, prevalence of colorectal neoplasms was higher in S. bovis biotype I (S. gallolyticus) bacteremia (80%) than in S. bovis biotype II (33.3%; p < 0.007). In conclusion, risk of colorectal neoplasm is high among cirrhotic patients with S. gallolyticus bacteremia.

RESUMO

BACKGROUND: Acute post-streptococcal glomerulonephritis (APSGN) is common in developing countries with a high hospitalization rate. Most patients have acute nephritic syndrome features, although some occasionally present with unusual clinical features. This study aims to describe and analyze clinical features, complications, and laboratory parameters in children diagnosed with APSGN at presentation, 4 and 12 weeks later, in a resource-limited setting. METHODS: This cross-sectional study was conducted among children < 16 years with APSGN between January 2015 and July 2022. Hospital medical records and outpatient cards were reviewed for clinical findings, laboratory parameters, and kidney biopsy results. Descriptive analysis of multiple categorical variables was performed using SPSS version 16.0 and presented as frequencies and percentages. RESULTS: The study included 77 patients. Most (94.8%) were older than five years, and age group 5-12 years had highest prevalence (72.7%). Boys were affected more frequently than girls (66.2% vs. 33.8%). Edema (93.5%), hypertension (87%), and gross hematuria (67.5%) were the most frequent presenting symptoms, and pulmonary edema (23.4%) was the most common severe complication. Anti-DNase B and anti-streptolysin O titers were positive in 86.9% and 72.7%, respectively, and 96.1% had C3 hypocomplementemia. Most clinical features resolved in three months. However, at 3 months, 6.5% of patients had persistent hypertension, impaired kidney function, and proteinuria alone or in combination. Most patients (84.4%) had an uncomplicated course; 12 underwent kidney biopsy, 9 required corticosteroids, and 1 required kidney replacement therapy. There was no mortality during the study period. CONCLUSION: Generalized swelling, hypertension, and hematuria were most common presenting features. Persistent hypertension, impaired kidney function, and proteinuria persisted in a small proportion who had a significant clinical course and required kidney biopsy. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMO

Preseptal cellulitis, an infection of the eyelid and skin around the eye, can be distinguished from orbital cellulitis. It is common in children and is rarely complicated. Streptococcus pyogenes is one of the major pathogens causing preseptal cellulitis. Here, we report a case of a 46-year-old man with carcinoma of unknown primary presenting preseptal cellulitis of S. pyogenes complicated by streptococcal toxic shock syndrome and multiple metastatic abscesses involving right eyelid, subcutaneous tissue in the scalp, mediastinum, bilateral pleural spaces, pericardial space, and the left knee. Although he required a prolonged hospitalization, antibiotic therapy and multiple courses of debridement led to full recovery. A literature review revealed that there were only four cases of preseptal cellulitis with S. pyogenes in adults and two cases were complicated by streptococcal toxic shock syndrome. The cases had either trauma or immunocompromising factors similar to our patient. All patients survived with antibiotic therapy and debridement, and the functional outcome was favorable. In summary, preseptal cellulitis caused by S. pyogenes can be severe in adult cases where immunocompromising factors and type of strain may play a role in the severity of the disease. Awareness of the risk of severe complications, treatment with appropriate antibiotic therapy, and timely debridement are crucial for favorable prognoses.

RESUMO

BACKGROUND Periprosthetic joint infection is a difficult complication, especially in patients with rheumatoid arthritis. Life-threatening septic shock due to periprosthetic joint infection caused by group G streptococcus is rare, and there have been few reports about its treatment. We describe a successful case of sudden onset septic shock due to group G Streptococcus infection after revision total knee arthroplasty. CASE REPORT A 61-year-old woman with rheumatoid arthritis treated with biological disease-modifying antirheumatic drugs for about 12 years presented with acute right knee pain and shock 6 months after revision total knee arthroplasty. Periprosthetic joint infection caused by group G Streptococcus was diagnosed. She was admitted to the Intensive Care Unit, treated with respiratory support and dialysis, and underwent irrigation, debridement, and polyethylene liner exchange as the first surgery. At 9 days after the first surgery, she underwent the second surgery, consisting of implant removal and antibiotic spacer placement due to failure. It took approximately 7 weeks to normalize the levels of systemic markers of inflammation with intravenous antibiotics and then oral antibiotics for further 12 weeks, but re-revision total knee arthroplasty was successfully performed 1.5 years later. At a 1-year follow-up from the final surgery, she was able to walk with a cane and had no symptoms of infection. CONCLUSIONS In such cases with sudden onset of septic shock due to periprosthetic joint infection, appropriate and prompt surgical treatment should be performed to save the infected limb as well as the patient's life.

RESUMO

Streptococcus gallolyticus subspecies gallolyticus (Sgg) is known to be strongly associated with colorectal cancer (CRC). Recent functional studies further demonstrated that Sgg actively stimulates CRC cell proliferation and promotes the development of colon tumors. However, the Sgg factors important for the pro-proliferative and pro-tumor activities of Sgg remain unclear. Here, we identified a chromosomal locus in Sgg strain TX20005. Deletion of this locus significantly reduced Sgg adherence to CRC cells and abrogated the ability of Sgg to stimulate CRC cell proliferation. Thus, we designate this locus as the Sgg pathogenicity-associated region (SPAR). More importantly, we found that SPAR is important for Sgg pathogenicity in vivo. In a gut colonization model, mice exposed to the SPAR deletion mutant showed significantly reduced Sgg load in the colonic tissues and fecal materials, suggesting that SPAR contributes to the colonization capacity of Sgg. In a mouse model of CRC, deletion of SPAR abolished the ability of Sgg to promote the development of colon tumors growth. Taken together, these results highlight SPAR as a critical pathogenicity determinant of Sgg.

RESUMO

OBJECTIVES: Viridans group streptococci (VGS) have been previously linked to infective endocarditis (IE) in patients with mitral valve prolapse (MVP). The species identification of VGS is now available in clinical laboratories; however, it has not been examined in MVP IE. Therefore, we detailed the clinical profile, species designations, and antibiotic susceptibility of VGS isolates from patients with MVP IE. METHODS: We retrospectively queried all adults with MVP and a definite or possible IE diagnosis seen at medical centers of the Mayo Clinic Enterprise from January 2009 to December 2021. Data, including clinical characteristics, comorbidities, microbiology, and outcomes, were extracted from electronic health records. VGS isolates from patients with MVP and IE were subclassified into mutans, salivarius, anginosus, sanguinis, and mitis groups. RESULTS: A total of 38 patients with MVP with IE due to streptococcal species were included. Overall, median age was 62.4 years and 32% of patients were females. The most prevalent comorbidities were diabetes mellitus (26%), hypertension (21%), heart failure (16%), and malignancy (16%). A total of (37%) patients presented with an embolic event at the time of their IE diagnosis, 27 (66%) required valve surgery, and no patient died within the hospital stay. The Streptococcus mitis group was the predominant (n = 17, 45%) species designation; S. anginosus and S. sanguinis were identified in three (8%) each; S. mutans in two (5%); and S. salivarius in one (3%). Non-VGS streptococcal pathogens included S. agalactiae in three patients (8%), S. equi in two (5%), and S. dysgalactiae and S. bovis in one each (3%). VGS were identified in five (13%) patients, but species designation was not done. No penicillin resistance was identified among the isolates. CONCLUSION: The S. mitis group was the predominant species in our investigation. Continued evaluation of VGS species should be considered to profile the IE risk based on species identification.

RESUMO

BACKGROUND: Acute post-streptococcal glomerulonephritis (APSGN) is an immune-mediated inflammatory respsonse in the kidneys caused by nephritogenic strains of group A ß-hemolytic streptococcus (GAS). The present study aimed to present a large patient cohort of APSGN patients to determine the factors that can be used for predicting the prognosis and progression to rapidly progressive glomerulonephritis (RPGN). METHODS: The study included 153 children with APSGN that were seen between January 2010 and January 2022. Inclusion criteria were age 1-18 years and follow-up of ≥ 1 years. Patients with a diagnosis that could not be clearly proven clinically or via biopsy and with prior clinical or histological evidence of underlying kidney disease or chronic kidney disease (CKD) were excluded from the study. RESULTS: Mean age was 7.36 ± 2.92 years, and 30.7% of the group was female. Among the 153 patients, 19 (12.4%) progressed to RPGN. The complement factor 3 and albumin levels were significantly low in the patients who had RPGN (P = 0.019). Inflammatory parameters, such as C-reactive protein (CRP), platelet-to-lymphocyte ratio, CRP/albumin ratio, and the erythrocyte sedimentation rate level at presentation were significantly higher in the patients with RPGN (P < 0.05). Additionally, there was a significant correlation between nephrotic range proteinuria and the course of RPGN (P = 0.024). CONCLUSIONS: We suggest the possibility that RPGN can be predicted in APSGN with clinical and laboratory findings.

RESUMO

INTRODUCTION: Streptococcus bovis/equinus complex (SBEC) is a major cause of infective endocarditis (IE), although its incidence varies greatly depending on the geographical area. The characteristics of IE caused by Streptococcus gallolyticus susp. gallolyticus are well known; there are hardly any descriptions of IE caused by other species or biotypes. METHODS: Retrospective cohort study, from 1990 to 2019, of all SBEC IE in adults in three Spanish hospitals, Lugo (LH), Barcelona (BH) and Ferrol (FH) where the population is mainly rural, urban and mixed, respectively. The incidence of IE was analyzed in 3 areas. Clinical characteristics of IE (277 cases, 258 biotyped) were compared according to SBEC species and biotypes. RESULTS: There are significant differences between the incidence of SBEC IE in HL (27.9/106) vs. HF and HB (8.8 and 7,1, respectively, p<0.001). We found significant differences (SbI vs. SbII) in mean age (68.5 vs. 73 years; p<0.01), duration of symptoms before diagnosis (46.9±46.5 vs. 30.4±40.9 days; p<0.01), presence of comorbidities: 39.1% (78) vs. 54.2% (32; p<0.04), predisposing heart illness:62.3% (124) vs. 81.3% (48; p<0.006), particularly, prosthetic or intravascular devices IE: 24.6% (49) vs. 52.4% (31; p<0.001), bi-valve involvement:23.6% (47) vs. 11.8% (7; p<0.05) and heart failure: 24.6% (49) vs. 38.9% (23; p<0.03). There were no significant differences in embolic events, need for surgery or mortality. The association with CRC was high in both groups: 77.7% vs. 66.6%. CONCLUSIONS: IE due to SBEC has geographical variations in incidence and different clinical characteristics among biotypes. The association with CRC was high.

RESUMO

Toxic shock-like syndrome (TSLS) is a life-threatening hyperinflammatory complication caused by Streptococcus species infections. We reported the first case of TSLS caused by primary bacteremia of Streptococcus agalactiae during chemotherapy for multiple myeloma. A 74-year-old woman, who received combination chemotherapy of elotuzumab, pomalidomide, and dexamethasone for treatment-refractory multiple myeloma, was transported to our hospital under comatose and septic shock. Her blood culture detected Streptococcus agalactiae, and considering the progressive multiorgan failure, she was diagnosed with TSLS. Empiric antibiotic treatment with meropenem and respiratory and circulatory support were quickly initiated, resulting in an almost complete recovery of organ functions. It should be noted that with the advances of chemotherapy, the risk of infection is becoming more diverse.
