Abstract

Background: Gram-negative organisms producing Extended-spectrum beta-lactamases (ESBLs) are presented as a global problem. Klebsiella pneumoniae is considered as one of the most important microorganism of this group. The prevalence rate of K. pneumoniae species is increasing, and this increase is higher in the ESBL group, indicating the increase in antibiotic resistance. We must have sufficient knowledge about regional antibiotics resistance in order to monitor the prevalence rate and antimicrobial resistance among the isolates by appropriate treatment. In this regard, the objective of our study was to evaluate antimicrobial susceptibility among K. pneumoniae isolates by E-test method in Khatam ol Anbia hospital during 2015.
Materials and methods: This descriptive cross-sectional study was carried out during 2015.  All clinical samples were collected from intensive care unit (ICU) and general wards of Khatam ol Anbia hospital. All of the K. pneumoniae strains were detected by biochemical and microscopic tests. Antimicrobial susceptibility and minimum inhibitory concentration (MIC) were determined by disk diffusion and E-test methods. Descriptive statistics was used to analyze data.
Results: About 62 K.  pneumoniae strains were isolated from clinical samples of ICU and general wards during one year. Of these, 38 (61.3%) isolates were isolated from intensive care unit, and 24 (38.7%) isolates were isolated from the general wards. In this review, the least resistance was related to colistin (4.8%) and Amikacin (14.5%), respectively, and the most resistance was observed to the antibiotics of ciprofloxacin (66.1%), ceftriaxone (62.9%) and gentamicin (59.7%), respectively. Resistance to imipenem was observed in 38.7% of the isolates.
Conclusion: The current study demonstrates that antibiotic resistance pattern is changing, and resistance to imipenem and colistin is rising, so this should be considered as a serious risk for admitted patients in hospital.

Abstract

Infective endocarditis (IE) is a rare but serious disease with different clinical pictures. Its neurological complication is commonly mistaken in term of diagnosis and treatment. Therefore, such cases must be taken under further diagnostic imaging for searching the basic structural lesions. Known causes of these signs include cardio embolism with hemorrhagic transformation, septic embolism, or mycotic aneurysms. In this paper, our case was a patient admitted for the evaluation of local neurological complaint reason and subsequent therapy. He was found to have bacterial endocarditis after medical workup. It was diagnosed prospectively from positive tests of vegetation on Transesophageal echocardiogram and Magnetic resonance imaging (MRI) results.

Abstract

Backgrounds: Currently, clinical details of immunosuppressed patients suffering from COVID-19 are limited. Some studies have shown no more severe diseases among them, but others have highlighted that immunosuppressed patients may have high levels of viral load and impaired immune responses. Herein, this study aimed to specifically address the symptoms, prognosis, laboratory tests, clinical course, and the outcome of SARS-CoV-2 infected immunocompromised patients at a tertiary referral center.
Materials & Methods: Clinical and laboratory information of 75 non-congenital immunosuppressed patients with COVID-19 disease was obtained at a referral center for immunodeficiency diseases and infectious disorders in Tehran, Iran. Three groups of immunocompromised patients were evaluated, including patients with a history of organ transplantation, autoimmune patients receiving medical therapy, and cancer patients undergoing chemotherapy.
Findings: Among 75 immune-deficient patients with COVID-19, there were 32 patients with a kidney transplant, 23 patients with malignancies, and 19 patients with autoimmune disorders. One patient had both malignancy and multiple sclerosis. The mean length of hospitalization was 10.82 days. By the end of the study, 24 (32%) patients were dead, and 51 (68%) patients were discharged. Dyspnea was the most common (64%) symptom. Low levels of O2 saturation and lymphopenia at admission time significantly affected the mortality rate of patients.
Conclusion: This study showed that mortality rate among immunocompromised patients was 32%. It seems that COVID-19 has a worse outcome and a more severe clinical course in immunocompromised patients regardless of age, gender, and underlying diseases.
