RESUMEN

Introduction Hospital-acquired infections, also called nosocomial infections, are infectious diseases acquired in healthcare facilities at least 48 hours after admission and can't be present at the time of admission. Nosocomial bloodstream infection is a serious medical complication from hospitalization, and it can be potentially preventable by taking certain precautions. Aim The aim of this study is to determine the prevalence of central line-related bloodstream infections (CLABSI) with different organisms between January 2022 and February 2024 at the intensive care unit (ICU) at Prince Mohammed bin Abdulaziz Hospital, Riyadh, Saudi Arabia. Patients and methods This retrospective cross-sectional study was conducted among ICU adult patients. The data were collected from medical and infection control records. All data for intensive care patients with positive blood cultures, except for the pediatric age group, were collected. Data were tabulated and cleaned in MS Excel, and subsequent data analyses were performed in IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). Results Data from 21 patients were collected and analyzed. The mean age of the participants was 62.9 (SD 15.1) years. Female participants (61.9% (13)) were higher than males (38.1% (8)). All patients were inserted with a non-tunneled central venous catheter (CVC). The mortality rate was 76.2% (16). Vancomycin-resistant enterococci (VRE) was the most commonly detected organism in seven cultures (33.3%), followed by Candida species in six cultures (28.6%). Candida species were prevalent in younger patients (p=0.021) and those sensitive to medication (p=0.015). Survival analyses between age, gender, and organisms yielded insignificant results (p>0.05). Conclusion The major sources of bloodstream infection among adult ICU patients were VRE and Candida species. Mortality was common in this population, particularly among patients who were resistant to medication. Hence, strategies to reduce hospital-acquired bloodstream infections are warranted.

RESUMEN

Thrombotic thrombocytopenic purpura (TTP) is a rare and potentially fatal disease. The majority of cases are caused by a significant enzyme deficiency in the blood called the von Willebrand factor (VWF) cleaving protease (also called ADAMTS13). TTP is classified as a hematologic emergency because of the high mortality rate. The diagnosis is difficult due to the extensive overlap in the clinical manifestations of TTP and other illnesses. Klebsiella pneumoniae infection can in very rare instances present with TTP and/or a metastatic-like presentation where the patient might have prostate, liver, brain, and lung abscesses mimicking late-stage solid organ malignancy. In this paper, we report a case of TTP secondary to Klebsiella pneumoniae infection in a 38-year-old male patient, who presented with fever, cough, and shortness of breath for five days. On examination, he was vitally unstable, confused, and not oriented, with a Glasgow Coma Scale (GCS) of 9/15. Complete blood count (CBC) showed a high white blood cell (WBC) count, very low platelet count, increased reticulocyte count, and significant elevation of schistocytes on peripheral blood film. Sputum and blood cultures were positive for Klebsiella pneumoniae. Computerized tomography (CT) scan chest showed bilateral lung parenchymal nodules. An abdominal ultrasound (US) scan detected a right hepatic lobe lesion that was both cystic and solid. The patient was initially started on meropenem, vancomycin, and levofloxacin due to shock presentation which was de-escalated to ceftriaxone later. The patient had five therapeutic plasma exchange sessions and was started on methylprednisolone for three days. The patient's situation gradually improved, and he was discharged later on. The second case is a 63-year-old-male patient who presented with fever, dry cough, night sweats, and dysuria for seven days. He was vitally stable, conscious, alert, and oriented. His hemoglobin was 9.6 g/dl. He was scheduled for an urgent colonoscopy to rule out colon cancer along with computed tomography (CT) scan of the chest, abdomen, and pelvis. The CT scan showed complex cystic lesions involving the right hepatic lobe, lungs, adrenal glands, and prostate. The clinical picture was suggestive of hyper-mucoid Klebsiella pneumoniae infection showering to the liver, adrenal glands, and prostate. A drained prostate collection and urine cultures confirmed the diagnosis. The patient was managed with surgical drainage of the collection in addition to ceftriaxone and metronidazole. The patient was discharged in good health on ciprofloxacin with follow-up as an outpatient.

RESUMEN

Cytomegalovirus (CMV) is a double-stranded DNA virus that belongs to the herpesvirus family. In the immunocompetent host, CMV infection is usually mild and goes unnoticed. Patients become prone to CMV infection as a result of immunosuppressive drugs or disorders that weaken cellular immunity. In severe COVID-19 infection, the patient experiences a drop in his T lymphocytes and becomes prone to opportunistic infections such as CMV colitis. In this paper, we presented a rare case of CMV colitis in a 54-year-old female with a positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) polymerase chain reaction. The patient was admitted to the intensive care unit and intubated due to the severity of her presentation. The patient received high-dose dexamethasone followed by a tapering dose of prednisolone. Fifteen days post-admission, the patient started to have melena with a drop in her hemoglobin. Sigmoidoscopy revealed ulcerated lesions that extended 5 cm proximally, and multiple biopsies confirmed the diagnosis of CMV colitis. The patient was started on ganciclovir 5 mg/kg intravenously for 21 days. The patient's symptoms improved to the point where she no longer complained of melena, and her hemoglobin level normalized. The patient was discharged home in stable condition, to be followed later in the outpatient clinic.
