Understanding clinical outcomes and factors influencing mortality in intensive care unit patients with COVID-19-associated candidemia.

BACKGROUND: During the COVID pandemic, research has shown an increase in candidemia cases following severe COVID infection and the identification of risk factors associated with candidemia. However, there is a lack of studies that specifically explore clinical outcomes and mortality rates related to candidemia after COVID infection. OBJECTIVES: The aim of this international study was to evaluate the clinical outcomes and identify factors influencing mortality in patients who developed candidemia during their COVID infection. PATIENTS/METHODS: This study included adult patients (18 years of age or older) admitted to the intensive care unit (ICU) and diagnosed with COVID-associated candidemia (CAC). The research was conducted through ID-IRI network and in collaboration with 34 medical centres across 18 countries retrospectively, spanning from the beginning of the COVID pandemic until December 2021. RESULTS: A total of 293 patients diagnosed with CAC were included. The median age of the patients was 67, and 63% of them were male. The most common Candida species detected was C. albicans. The crude 30-day mortality rate was recorded at 62.4%. The logistic regression analysis identified several factors significantly impacting mortality, including age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.07, p < .0005), SOFA score (OR 1.307, 95% CI 1.17-1.45, p < .0005), invasive mechanical ventilation (OR 7.95, 95% CI 1.44-43.83, p < .017) and duration of mechanical ventilation (OR 0.98, 95% CI 0.96-0.99, p < .020). CONCLUSIONS: By recognising these prognostic factors, medical professionals can customise their treatment approaches to offer more targeted care, leading to improved patient outcomes and higher survival rates for individuals with COVID-associated candidemia.

Clinicopathological profile of peritoneal tuberculosis and a new scoring model for predicting mortality: an international ID-IRI study.

Existing literature about peritoneal tuberculosis (TBP) is relatively insufficient. The majority of reports are from a single center and do not assess predictive factors for mortality. In this international study, we investigated the clinicopathological characteristics of a large series of patients with TBP and determined the key features associated with mortality. TBP patients detected between 2010 and 2022 in 38 medical centers in 13 countries were included in this retrospective cohort. Participating physicians filled out an online questionnaire to report study data. In this study, 208 patients with TBP were included. Mean age of TBP cases was 41.4 ± 17.5 years. One hundred six patients (50.9%) were females. Nineteen patients (9.1%) had HIV infection, 45 (21.6%) had diabetes mellitus, 30 (14.4%) had chronic renal failure, 12 (5.7%) had cirrhosis, 7 (3.3%) had malignancy, and 21 (10.1%) had a history of immunosuppressive medication use. A total of 34 (16.3%) patients died and death was attributable to TBP in all cases. A pioneer mortality predicting model was established and HIV positivity, cirrhosis, abdominal pain, weakness, nausea and vomiting, ascites, isolation of Mycobacterium tuberculosis in peritoneal biopsy samples, TB relapse, advanced age, high serum creatinine and ALT levels, and decreased duration of isoniazid use were significantly related with mortality (p < 0.05). This is the first international study on TBP and is the largest case series to date. We suggest that using the mortality predicting model will allow early identification of high-risk patients likely to die of TBP.

The Effects of Laboratory Parameters on the Prognosis of COVID-19.

OBJECTIVE: While the coronavirus disease 2019 pandemic is an ongoing issue across the world, understanding the course of the disease is important for early diagnosis and treatment. We aimed, with this study, to determine the differences between laboratory parameters in different clinical pictures of coronavirus disease 2019. MATERIALS AND METHODS: The study included 443 patients who presented to Atatürk University Medical Faculty Hospital between March 15, 2020, and June 15, 2020, and were diagnosed with coronavirus disease 2019 upon a positive Real Time Polymerase Chain Reaction (RT-PCR) result. The hospitalized patients were divided into 4 groups based on their clinical status. The roles of these markers in determining the severity of coronavirus disease 2019 were statistically evaluated. RESULTS: A total of 443 patients with RT-PCR confirmation were included in the study. The mean age was 46.0 ± 19.1 years and 54.4% of the patients were male. According to the clinical classification, 16.3% of the cases were asymptomatic, 25.7% uncomplicated, 35.7% mild/moderate, and 22.3% severe. The first 3 most frequent symptoms were cough (21.3%), fever (17.7%), and fatigue (15.5%). Hypertension (36.1%) was the major comorbidity among the patients. During the follow-up of severe cases, 39.4% developed the need for intensive care. The overall mortality rate, on the other hand, was 4.7%. Regarding laboratory parameters, procalcitonin (PCT), serum ferritin, erythrocyte sedimentation rate, C-reactive protein, neutrophil count, D-dimer, troponin, and lactate dehydrogenase were at the highest level in the severe patient group while albumin, platelet, and lymphocyte count were found to be at the lowest level in the same group. A statistically significant difference was detected between the groups (P < .001). CONCLUSION: The increase in C-reactive protein, PCT, erythrocyte sedimentation rate, ferritin, troponin, D-dimer, lactate dehydrogenase, and neutrophil count and the decrease in albumin, platelet, and lymphocyte count are significant in the severe patient group; it has been concluded that they can be used to determine the severity of coronavirus disease 2019.

Investigation of antibiotic susceptibilities of Brucella Strains isolated from various clinical samples in eastern Turkey.

BACKGROUND: Brucellosis is a worldwide zoonotic disease that causes serious public health problems. This study aimed to identify Brucella strains isolated from various clinical samples by conventional and molecular methods and to determine antimicrobial susceptibilities against doxycycline (DOX), streptomycin (STR), ciprofloxacin (CIP) and rifampicin (RIF) by the gradient strip (E test) test method. METHODS: A total of 87 Brucella strains isolated from various clinical specimens between 2004 and 2018 were included in this study. While four of the 87 strains included in the study were identified only at the genus level, the remaining 83 strains were identified at the species level by the Real-Time Multiplex PCR (M-RT-PCR) method and conventional methods were used for biotyping. RESULTS: According to molecular identification results, 83 strains were identified as B. melitensis by the M-RT-PCR method, with 82 strains identified as Brucella melitensis biovar (bv) 3 and one as B. melitensis bv 1 according to the conventional biotyping method. Among the antibiotics studied, CIP was found to be the most active agent according to the minimum inhibitory concentrations (MIC)90 values. This was followed by DOX and STR, respectively. While all of the isolates were sensitive to CIP, DOX and STR, 18 (20.7%) strains were found to be moderately susceptible to RIF, with the highest values of MIC50 and MIC90. CONCLUSIONS: In our study, all strains were identified as B. melitensis. DOX, STR, CIP and RIF used in the treatment of brucellosis were found to be effective.

Factors affecting the mortality at patients with burns: Single centre results.

BACKGROUND: Burns are a primary cause of mortality along with the severe physical and psychological morbidities in patients and their families. Such kinds of injuries bring about considerable financial burdens due to the treatment processes and sequels. The present study aims to investigate the factors that affect the mortality of burns. METHODS: The archives files of the patients admitted because of burn injuries in our burn centre between September 2008 and December 2016 were examined in this study. Some of the lab values, such as age, sex, percentage of total burn surface area (TBSA), referral status, burning site, degree of burns, time of admission to hospital, aetiology of burning, blood and blood products collection, complete blood count, routine biochemistry, coagulation parameters, C-reactive protein (CRP), sedimentation rate, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), were examined while evaluating the patients' mortalities. RESULTS: A total of 133 patients were included in this study. The patient's age (p=0.001), the degree of burns (p<0.001), surface area of burns (p<0.001), the time of hospital admission (p<0.001), burning aetiology (p=0.006), erythrocyte suspension, fresh frozen plasma, along with the administration of albumin transfusion (p<0.001), mean platelet volume (MPV) (p=0.028), NLR (p<0.001) and PLR (p<0.030) values were found to be associated with mortality in patients with burns. CONCLUSION: In this study, age, burn grade, TBSA, hospital admission time, burn aetiology, erythrocyte, fresh frozen plasma and albumin transfusion, MPV, NLR and PLR values were found to be associated with mortality in patients with burns. With this study, it is possible to produce the treatment guidelines to reduce mortality by taking these parameters into consideration, which were determined to be associated with mortality while evaluating the patients with burns.

Changes in acute viral hepatitis epidemiology in the Turkish adult population: A multicenter study.

BACKGROUND/AIMS: The present study aimed to determine the changes in the epidemiology of hepatitis in recent years in an adult Turkish population. MATERIALS AND METHODS: Overall, 852 patients with acute viral hepatitis from 17 centers were included in this study. Their sociodemographic characteristics, clinical courses, treatments, and laboratory findings were retrospectively analyzed. RESULTS: The most commonly found microorganisms were the hepatitis B virus (55.2%) and hepatitis A virus (37.6%), and the types of acute viral hepatitis differed significantly according to the age group (p≤0.001). The most frequently reported symptom was fatigue (73.7%), and the most common complications were cholecystitis (0.4%) and fulminant hepatitis (0.4%). The median hospital stay was 9 days (range 1-373). In total, 40.8% patients with acute hepatitis B virus developed immunity. CONCLUSION: In Turkey, there are significantly large adolescent and adult populations susceptible to acute viral hepatitis. Therefore, larger vaccination programs covering these age groups should be implemented.

[Evaluation of epidemiologic and clinical features of oropharyngeal tularemia patients in the Eastern Anatolia Region of Turkey]. / Dogu Anadolu Bölgesi'nden hastanemize basvuran orofarengeal tularemi olgularinin epidemiyolojik ve klinik özelliklerinin degerlendirilmesi.

Tularemia is a zoonotic infectious disease caused by Francisella tularensis. Tularemia is endemic in the northern hemisphere and is usually seen in North America, Europe and Asia. Although the ulceroglandular tularemia is the most common form in these regions, the oropharyngeal form is more prevalent in Eastern Europe, including Turkey. The disease has importance in Turkey due to its wide geographic distribution and periodic outbreaks. The aim of this study was to determine the demographic, clinical and epidemiological characteristics of oropharyngeal tularemia patients. The demographic, clinical, epidemiological and laboratory findings of 26 tularemia patients admitted to our hospital from Erzurum and 5 neighbour provinces were analyzed retrospectively. Francisella tularensis microagglutination test (MAT) was performed for all patients whose clinical symptoms were consistent with tularemia and MAT titers ≥ 1/160 were considered positive. Twenty-six oropharyngeal tularemia patients (13 males and 13 females) were included in the study. All of the patients had cervical lymphadenopathy (LAP) at least one month period. Twenty (76.9%) of the patients included in the study were living in rural areas, and 17 (65.4%) were dealing with livestock. It was determined that 9 (34.6%) of the patients used water from municipal water supply, 9 (34.6%) of the patients used water from natural water supply and 8 (30.8%) of the patients used both of the water supplies. The most common symptoms among the patients in the study were fever in 23 (88.5%) patients, sore throat in 24 (92.3%) patients, and cervical LAP in all of the patients. Thirteen (50%) of the patients were treated with streptomycin, 7 (26.9%) with doxycycline and 6 (23.1%) with gentamicin. This is the first study showing that tularemia is present in Erzincan, Agri, Igdir as well as Erzurum provinces, and it provides that the incidence has increased in this region. Tularemia diagnosis is generally underestimated due to the lack of specific symptoms. Therefore, tularemia should also be considered in patients who have complaints of sore throat and cervical LAP in non-endemic regions.

A retrospective analysis of 2713 hospitalized burn patients in a burns center in Turkey.

BACKGROUND: Burn trauma is a significant health problem that has physical, psychological, and economic repercussions on affected patients. The aim of this study was to present epidemiological and demographic characteristics of patients treated over an 8-year period at a reference burn treatment center located in the northeast of Turkey and serving a population of approximately four million people. METHODS: Each patient's medical record was reviewed, and demographic features, source of burns, place of residence, total body surface area (TBSA), surgical treatment, duration of hospital stay, and mortality rates were analyzed. RESULTS: The most frequent cause of burn was scalding from hot liquids (2013 cases, 74.2%). Freeze burn was observed in 16 (0.6%) cases due to climatic conditions of the region where our burn center is located. Grouping based on TBSA revealed that 88.7% patients had TBSA of 0%-15%, 8% patients had TBSA of 15%-30%, and 3.3% patients had TBSA ≥ %30.The most common microorganism was Pseudomonas aeruginosa. A total of 24 patients (0.9%; 8 males, 16 females) died, including 7 children and 17 adults. CONCLUSION: Removal of tandirs and replacement with high ovens, restriction of cheese and butter production under primitive circumstances, encouraging cheese and butter production via dairy farm systems, and raising people's awareness through training programs could greatly reduce the number of the burn accidents occurring in this region.

Breast Recurrent Hydatid Cyst Disease.

Introduction: Hydatid cyst is a zoonotic disease seen in endemic areas. It is an important health problem in our country and especially in our Eastern and South-eastern Anatolia Region. Involvement of isolated breast tissue is very rare in hydatid cystdisease. As far as we know, isolated recurrent breast cyst hydatidosis has not been found in the literature. CASE REPORT: We aimed to present the case of a patient who was diagnosed with recurrent isolated cyst hydatid in the same breast, operated on because of hydatid cyst in the right breast 9 years ago. CONCLUSION: A hydatid cyst should be considered, particularly in endemic regions, in the differential diagnosis of cystic masses of the breast. If the patient has previously undergone surgery for breast cyst hydatid disease, recurrent cyst hydatid disease should be considered at the differential diagnosis.

Is Serum Angiotensin-Converting Enzyme Level Useful For Determining Necroinflammatory Activity In Chronic Hepatitis B Infection?

AIM: The purpose of this study was to investigate the relationship between the findings from liver biopsy and the serum angiotensin-converting enzyme (ACE) level to determine whether ACE might serve as a potential noninvasive sign of necroinflammatory activity in patients with Chronic Hepatitis B (CHB) infection. METHODS: A total of 54 CHB patients referred for liver biopsy were enrolled in the study. Serum ACE levels were determined photometrically with a kinetic test. RESULTS: The aspartate aminotransferase (AST), alanine aminotransferase (ALT), hepatitis B virus-deoxyribonucleic acid (HBV-DNA), histological activity index (HAI), and white blood cell counts were higher in patients with severe fibrosis, while albumin levels were low. The serum ACE levels showed a statistically significant correlation with HBV-DNA, HAI score, and ALT-AST levels. DISCUSSION: In this study, a statistically significant relation between serum ACE levels and HAI scores was observed. This represents the first analysis to compare necroinflammation of the liver and serum ACE levels. There may be some explanations that the suppression of hepatocyte growth factor (HGF) by Angiotensin II and increased inflammatory damage might be a reason for the correlation between HAI and ACE. Serum ACE levels, HBV-DNA levels, and serum transaminase levels might be used together as noninvasive markers for the prediction of necroinflammation in CHB patients.

The role of diminishing appetite and serum nesfatin-1 level in patients with burn wound infection.

BACKGROUND: The burn wound represents a susceptible site for opportunistic colonization by organisms of endogenous and exogenous origin. Diminishing appetite is known to occur in patients with burn infection, yet its underlying reason is not fully understood. We have examined the levels of nesfatin 1, a protein that we consider to be a potential new treatment target for the solution of appetite and nutrition problem in patients with burn infection. OBJECTIVES: The aim of the present study was therefore to examine nesfatin levels in patients with burn infection. MATERIAL AND METHODS: Laboratory values, medication and dietary records, and patient notes with diagnostic information of burn wounds patients who were admitted to the Division of Burn Treatment Center were obtained from the Erzurum Region Education and Research Hospital electronic database. Post-burn wound infection was objectively assessed by culturing wound homogenates from skin tissue. The main immediate inflammatory stress response parameters assessed were serum CRP concentrations, WBC counts, and blood nesfatin concentrations. RESULTS: Scalding was the predominant cause of burns in both categories of patients. In 19 (61.3%) burn wound infection patients, the burns were due to a scald. A significant difference was found for the nesfatin, CRP, and WBC levels between the patients and the control group (P = 0.000). A significant difference was also determined between the nesfatin, CRP, and WBC figures at the time of hospitalization and at discharge from the hospital (P = 0.000). The most predominant bacterial isolate was Pseudomonas aeruginosa 16 (51.6%) followed by Methicilline resistant Staphylococcus aureus (MRSA) 7 (22.6%). CONCLUSIONS: We showed that the serum nesfatin 1 level was significantly lower in the patients with burn than in the control group in our study. We considered that the central nesfatin 1 system should be taken into consideration, rather than the peripheric nesfatin 1 system, when considering the regulation of appetite in patients with burns and particularly those accompanied by infection. In other explanation of the observed negative correlation between nesfatin 1 and burn wound infection suggests that nesfatin 1 may indicate the possible contribution of nesfatin 1 to the energy homeostasis.

A case of bacillary angiomatosis developed at a burn site.

Bacillary Angiomatosis (BA) is frequently seen in patients with human immunodeficiency virus (HIV)-induced immunodeficiency. Our patient was a case that developed granuloma-like lesions in the area of a burn, 8 days after being burnt on the upper right arm by scalding water. No indication of immune deficiency was observed and no history of direct contact with cats was evident. By the sixth day of the patient's admission to our clinic, some of the lesions had reached a diameter of 2.5 cm. An excision biopsy was carried out from the lesions present on the patient. Electron microscopy revealed solitary bacilli located close to the capillary wall. Oral erythromycin treatment was implemented at 250 mg, 4 times a day for 2.5 months. Within this period of treatment, the lesions regressed completely, and a complete cure was achieved. This case demonstrates that BA must be considered in the differential diagnosis of both HIV-infected and immunocompetent patients.

DRESS syndrome with fatal results induced by sodium valproate in a patient with brucellosis and a positive cytoplasmic antineutrophilic cytoplasmic antibody test result.

DRESS syndrome is a life-threatening adverse reaction characterized by skin rashes, fever, leukocytosis with eosinophilia or atypical lymphocytosis, lymph node enlargement, and liver or renal dysfunctions. DRESS syndrome related to valproic acid use is very rarely observed. We present a case of DRESS syndrome induced by sodium valproate, which developed and progressed fatally in a brucellosis patient with a positive c-ANCA test. A 19-year-old female patient presented with fever, cough, jaundice, and rash all over her body. Brucella Coombs test was positive at 1:1280 titers, and the Rose Bengal test was also positive. The involuntary movements were thought to be due to chorea, and the patient was started on sodium valproate 500 mg 2 1, as well as streptomycin 1 g flk 1 1 and tetradox capsules 2 1 for the brucellosis and was discharged. DRESS syndrome was suspected in the patient, and she was taken off sodium valproate and tetradox; N-acetylcysteine, ceftriaxon, prednizolone, and support treatment were started. When sodium valproate is used on its own, it carries no risk of inducing DRESS syndrome. However, in the case presented, another co-morbidity such as brucellosis and c-ANCA positivity was present. We believe that the presence of further co morbidity not yet reported in literature is important from the perspective of the risk of valproate-induced DRESS syndrome. Therefore, if sodium valproate treatment is to be started in patients, especially those with co morbidity, they must be closely monitored with clinical and laboratory observations. At the slightest suspicion of DRESS syndrome, all medication should be ceased immediately and the patient should be placed under continuous observation.
