sultamicillin and Streptococcal-Infections

We report a rare case of suppurative thrombophlebitis of the posterior neck caused by Streptococcus constellatus. A 69-year-old female patient was admitted to the hospital with neck pain and fever, which had persisted for 16 days prior to hospitalization. On day 1 (day of admission), blood cultures (later identifying S. constellatus) were performed, and ceftriaxone (CTRX) IV (2 g SID) was started. On day 3, suppurative thrombophlebitis of the posterior neck was diagnosed by CT scan. The antimicrobials were changed from CTRX to ampicillin/sulbactam IV (12 g QID) to guard against the possibility of complicated infection with Fusobacterium spp. or Prevotella spp. On day 17, a CT scan revealed that the thrombus remained. Therefore, oral edoxaban (30 mg SID) was started. On day 27, the patient was discharged after her medication was changed to oral amoxicillin/clavulanate (1500 mg/375 mg TID). On day 33, the amoxicillin/clavulanate was changed to oral cefaclor (1500 mg TID) and edoxaban was discontinued due to itching. On day 45, the course of cefaclor was completed. The patient went on to follow an uneventful course with no relapses or complications for two years since the conclusion of treatment. These results suggest that when a patient presents with persistent neck pain accompanied by fever, suppurative thrombophlebitis of the posterior neck should be considered. In antimicrobial therapy, the treatment could be switched from intravenous to oral. In addition, direct-acting oral anticoagulants may be an alternative to other forms of anticoagulants.

A 73-year old man was brought to our hospital because of acute onset of fever and consciousness disturbance. He had been hemodialyzed three times a week because of chronic renal failure since 13 years ago. Neurological examination revealed deteriorated consciousness and neck stiffness. A lumbar puncture yielded clouded fluid with a WBC 7,912/mm³ (polymorphonuclear cells 88%, mononuclear cells 12%), 786 mg/dl of protein and 4 mg/dl of glucose (blood glucose 118 mg/dl). Brain CT and MRI were unremarkable. He was treated with ceftriaxone and ampicillin. Streptococcus salivarius was isolated from the blood sample, but not from cerebrospinal fluid. The patient responded promptly to antibiotics therapy (ampicillin 3g/day, ceftriaxone 1g/day), and within several days he became lucid and afebrile. Isolated S. salivarius was sensitive for ampicillin and ceftriaxone. We diagnosed this case as S. salivarius bacteremia/meningoencephalitis. A gastrointestinal diagnostic workup revealed an asymptomatic gastric adenocarcinoma. S. salivarius is a common inhabitant of the oral mucosa that has been associated with infection in different sites. Meningeal infection by S. salivarius generally related to neoplasia of colon or iatrogenia, has been described on few occasions. This is the first report of S. salivarius bacteremia/meningoencephalitis associated with gastric neoplasm. Neurologist should be aware of the association of S. salivarius bacteremia/meningoencephalitis and gastrointestinal disease.

In an open prospective study, the efficacy of sulbactam/ampicillin (50 and 100 mg/kg, respectively, qid) was evaluated in 21 patients with intracranial abscess(es). Sixteen patients had cerebral, 3 epidural, and 2 cerebellar abscesses. Multiple lesions were found in 7 patients. Sixteen patients underwent surgical intervention, others were treated with antibiotic alone. The mean duration of antibiotic therapy (+/- SD) was 48 +/- 10 days (range 26-65 days). The mean duration of follow-up after completion of therapy (+/- SD) was 6 +/- 2.4 months. All patients had at least some reduction in size of abscess(es) within 3 weeks of the initiation of therapy as monitored by computerized tomography. Seventeen patients were cured, three patients died due to causes unrelated to their infection. One patient was reoperated since no clear improvement either clinically or radiologically was observed 18 days after the first operation. Side effects of sulbactam/ampicillin were minor and transient. Results obtained in this study indicate that sulbactam/ampicillin can be used in the treatment of intracranial abscesses, alone or with surgical intervention.

A total of 124 patients with lower respiratory tract (44) or urinary tract infections (80) were enrolled in an open, multicenter study to evaluate the efficacy and tolerability of sulbactam/ampicillin, administered at the dosage of 3 g/die by intramuscular route. Pretreatment pathogens from patients with lower respiratory tract infections included: Streptococcus alpha-haemolyticus in 8 cases, Streptococcus beta-haemolyticus in 2 cases, Staphylococcus albus in 7 cases, Haemophilus influenzae in 7 cases, Staphylococcus aureus in 6 cases, Klebsiella oxytoca in 5 cases, Staphylococcus epidermidis in 3 cases, Streptococcus pneumoniae in 3 cases, Escherichia coli in 2 cases; in one subject (2.75%), no microorganisms were isolated. In vitro, 36 isolates (84%) were sensitive to SA and 7 (16%) were resistant. At the end of therapy, all the causative pathogens sensitive to sulbactam/ampicillin were eliminated. In patients with urinary tract infections, pretreatment pathogens were: E. coli in 40 cases, S. albus in 16 cases, Proteus mirabilis in 8 cases, Enterobacter agglomerans in 6 cases, Proteus vulgaris in 3 cases, Streptococcus faecalis in 3 cases, Streptococcus liquefaciens in 2 cases, Pseudomonas aeruginosa in 2 cases. In vitro, 64 isolates (80%) were sensitive to sulbactam/ampicillin and 16 (20%) were resistant. At the end of therapy, 63 out of the 64 pathogens sensitive to sulbactam/ampicillin were eliminated; in one case the therapy was interrupted due to adverse effect. Clinical efficacy: in subjects with lower respiratory tract infections, sulbactam/ampicillin cured 32 patients (72.72%) and ameliorated the clinical status of 8 patients (18.18%); efficacy rate: 90.9%).(ABSTRACT TRUNCATED AT 250 WORDS)

In a prospective study 105 children hospitalized with soft tissue infection, 11 children with suppurative arthritis and 9 children with osteomyelitis were treated with either parenterally administered ampicillin/sulbactam or ceftriaxone. Treatment was randomized using a computer-generated table in a 2:1 fashion: 84 patients received ampicillin/sulbactam and 41 patients received ceftriaxone. Organisms isolated from wound site or blood cultures included Staphylococcus aureus (33), Streptococcus pyogenes (19), Haemophilus influenzae (9) including 4 beta-lactamase-positive organisms, Streptococcus pneumoniae (5), Neisseria gonorrhoeae (3) and 9 other organisms. Clinical and bacteriologic response was satisfactory in 100% of the ampicillin/sulbactam-treated patients and in 93% of the ceftriaxone-treated patients. Two patients with S. aureus infections treated with ceftriaxone had a delayed response and required change in therapy to parenterally administered oxacillin. Ampicillin/sulbactam represents a potentially useful single agent for the treatment of cellulitis and bone or joint infections in pediatric patients.

Fifty-two children with superficial skin and soft tissue infections were randomized to receive sultamicillin or cloxacillin for 7 days. Twenty-one children in each group finished the study. A total of 16 of 21 in the sultamicillin group and 13 of 21 in the cloxacillin group were cured. One child in the sultamicillin group and two in the cloxacillin group failed therapy. Four children who received sultamicillin and six who received cloxacillin had recurrences of lesions. Differences were not statistically significant.

Fifty-two children with positive pharyngeal cultures for group A streptococci were randomized to receive phenoxymethyl penicillin or sultamicillin, an ester of ampicillin and sulbactam. By serological and bacteriological criteria, sultamicillin was effective in 100% of the 20 evaluable cases of infection and carriage while penicillin was effective in six out of eight (75%) and three out of eight (93%) respectively. Of the eight children with infections treated with sultamicillin, three (37.5%) became recolonized with the organism compared to none of the children in the penicillin group. These differences were not statistically significant.

The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide. Bacterial co-infections are associated with unfavourable outcomes in respiratory viral infections; however, microbiological and antibiotic data related to COVID-19 are sparse. Adequate use of antibiotics in line with antibiotic stewardship (ABS) principles is warranted during the pandemic. We performed a retrospective study of clinical and microbiological characteristics of 140 COVID-19 patients admitted between February and April 2020 to a German University hospital, with a focus on bacterial co-infections and antimicrobial therapy. The final date of follow-up was 6 May 2020. Clinical data of 140 COVID-19 patients were recorded: The median age was 63.5 (range 17-99) years; 64% were males. According to the implemented local ABS guidelines, the most commonly used antibiotic regimen was ampicillin/sulbactam (41.5%) with a median duration of 6 (range 1-13) days. Urinary antigen tests for Legionella pneumophila and Streptococcus peumoniae were negative in all cases. In critically ill patients admitted to intensive care units (n = 50), co-infections with Enterobacterales (34.0%) and Aspergillus fumigatus (18.0%) were detected. Blood cultures collected at admission showed a diagnostic yield of 4.2%. Bacterial and fungal co-infections are rare in COVID-19 patients and are mainly prevalent in critically ill patients. Further studies are needed to assess the impact of antimicrobial therapy on therapeutic outcome in COVID-19 patients to prevent antimicrobial overuse. ABS guidelines could help in optimising the management of COVID-19. Investigation of microbial patterns of infectious complications in critically ill COVID-19 patients is also required.

Deep neck infections are important otolaryngologic emergencies due to serious complications and the risk of airway compromise, which can lead to mortality. Although the most common causes among pediatric patients are tonsillitis and pharyngeal infections, odontogenic infections are an important cause in adults.. We present three patients with multiple deep neck space abscess formation due to odontogenic infection. Two of them required tracheotomy due to airway compromise, and one had mediastinitis.. An underestimated tooth infection can cause hazardous complications such as mediastinitis and respiratory distress requiring tracheotomy.

Group B streptococcus (GBS) infection remains a leading cause of serious neonatal and early infantile infection. As the infection often presents with nonspecific symptoms, and is associated with underlying bacteremia, prompt investigation and treatment is required. We report a case of late, late-onset GBS infection with bacteremia in a 94-day-old boy experiencing cellulitis of the left hand. Although late-onset disease or late, late-onset disease has been reported to be common among infants with underlying conditions such as premature birth, immunocompromised status, trauma, or among those using medical devices, no such underlying medical condition predisposed this infant to invasive GBS infection. Recent reports including the present case underscore the risk of GBS infection among previously healthy infants beyond the neonatal period. Thus, clinicians should especially be aware of unusual presentations of GBS invasive disease with bacteremia.

A 10-year-old boy presented with a 2.5-week history of right leg pain and limp. A right flank mass was noted by a parent on the day of presentation. The child's past medical history was remarkable for perforated appendicitis treated with an interval laparoscopic appendectomy 2 years before this presentation. Abdominal and pelvic computed tomography revealed a retroperitoneal mass with calcifications, suggestive of a retained appendicolith with abscess formation. This case illustrates the importance of considering very late complications of appendicitis in patients presenting with fever and abdominal or flank pain or masses.

Group C streptococci are flora members of skin, nasopharynx, gastrointestinal and genitourinary systems. They are rare causes of human pharyngitis, arthritis, pneumonia, meningitis and bacteremia. In this report, a 71-years old male patient with Streptococcus equisimilis arthritis/prosthetic joint infection has been presented. The patient was admitted to the emergency service with the complaints of erythema, swelling and tenderness on right knee which had total knee prosthesis. Examination of synovial fluid punction sample yielded abundant amount of leukocytes (> 1000 cells/mm3). Empirical ampicillin-sulbactam (1 g q6h, parenterally) therapy was initiated. Bacteria which have been cultivated from synovial fluid specimen were identified as S. equisimilis. The isolate was found to be susceptible to penicilin, erythromycin and teicoplanin, and resistant to chloramphenicol and tetracycline. Although clinical presentation improved during the first ten days, symptoms recurred after the 10th day and the therapy was switched to teicoplanin. The recurrence was thought to be the result of antibiotic tolerence. The patient was treated successfully with teicoplanin, and no relapse or reinfection was observed during one year of follow-up. To our knowledge this is the first case of S. equisimilis arthritis reported from Turkey and first case of S. equisimilis associated prosthetic joint infection.

Occasionally, trivial odontogenic infections may develop into complex diseases. This may even result in an unrestrained phlegmonous spread causing life-threatening complications. These problems have decreased since the introduction of antibiotics and also due to improved oral hygiene and improved diagnostic measures resulting in optimized medical treatment. However, life-threatening forms are still seen, in particular if infections spread along the cervical fascial sheaths down towards to the mediastinum. Over the past decade the number of critical infections has increased in other medical specialties. This is usually explained by the development of multiresistant pathogens in the context of nosocomial infections.. We reviewed the patients' records of the past 15 years at the Department of Oral and Maxillofacial Surgery of the University Hospital Kiel to assess a possible increase of odontogenic infections with life-threatening complications. From 1990 to 2004, four patients with odontogenic infections exhibiting critical phlegmonous spread were treated in the intensive care unit. Two patients developed bacterial mediastinitis which could be controlled by intravenous antibiotics only. One patient progressed to general septic mediastinitis and eventually died of cardiorespiratory arrest. The last patient also had septic mediastinitis and developed right pleural empyema. Several operations were necessary before the disease could be controlled. This patient's case report is presented in detail.. The prognosis of patients with mediastinitis crucially depends on (a) early diagnosis including computed tomography of the neck and thorax, (b) early radical surgical intervention, and (c) optimized pathogen-oriented antibiotic treatment.

A 64-year-old woman with periodontal disease was admitted because of fever, right chest pain, and bloody sputum. Her chest radiograph revealed a nodular shadow in the right middle lung fields. From the results of a needle aspiration biopsy, she was diagnosed with a lung abscess due to Actinomyces odontolyticus (A. odontolyticus) and Streptococcus spp. The patient improved quickly with antibiotics. To our knowledge, only nine cases of pulmonary infection due to A. odontolyticus have been reported, and we report the first case in Japan. Although respiratory disease caused by A. odontolyticus is rare, the association of this organism should be considered even in healthy individuals.

Group F streptococci are gram-positive cocci typically isolated from wound infections and abscesses. Bacteremia with group F streptococcus is uncommon, and the lower gynecologic tract has not been reported as a source. We report a case of a Bartholin's abscess leading to group F streptococcal bacteremia.. A 31-year-old female noted fever and rigors 30 min after manipulation of a 3-day-old vulvar abscess. An empty Bartholin's gland abscess was found on examination, and blood cultures grew beta-hemolytic group F streptococci. The patient was treated with ampicillin/sulbactam, symptoms improved, and follow-up blood cultures revealed no growth.. Group F streptococci are known to inhabit various body sites and have a predilection for forming abscesses; however, bacteremia is infrequent. They have occasionally been identified in true infections of the genitourinary tract but only very rarely in Bartholin's abscesses. This case of group F streptococcal bacteremia following self-drainage of a Bartholin's abscess constitutes the first such description in the medical literature.
