CT visual quantitative evaluation of hypertensive patients with coronavirus disease (COVID-19): Potential influence of angiotensin converting enzyme inhibitors / angiotensin receptor blockers on severity of lung involvement.

OBJECTIVE: There is not enough data on the effect of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) on lung involvement in patients with COVID-19 pneumonia and hypertension (HT). Our aim was to compare the lung involvement of the HT patients hospitalized for COVID-19 using ACEIs/ARBs with the patients taking other anti-HT medications. METHODS: : Patients who have a diagnosis of HT among the patients treated for laboratory-confirmed COVID-19 between 31 March 2020 and 28 May 2020 were included in the study. One hundred and twenty-four patients were divided into two as ACEIs/ARBs group (n = 75) and non-ACEIs/ARBs group (n = 49) according to the anti-HT drug used. The chest CT involvement areas of these two groups were evaluated quantitatively by two observers including all lobes, and total severity score (TSS) was calculated. These TSS values were compared between drug groups and clinical groups. RESULTS: In clinical classification; there were 4 (%3.2) asymptomatic, 5 (4.0%) mild type, 92 (74.1%) common type, 14 (11.3%) severe type, 9 (7.3%) critical type patients. ACEI/ARB group's TSS (mean±SD, 7.74 ± 3.54) was statistically higher than other anti-HT medication group (mean±SD, 4.40 ± 1.89) (p < .001). Likewise, severe-critical clinical type's TSS (mean±SD, 9.17 ± 3.44) was statistically higher than common type (mean±SD, 5.76 ± 3.07) (p < .001). Excellent agreement was established between the two blinded observers in the TSS measurements. CONCLUSIONS: Quantitative evaluation of CT and TSS score can give an idea about the clinical classification of the patient. TSS is higher in ACEI/ARB group than non-ACEIs/ARBs group.

Surgical Antimicrobial Prophylaxis Compliance in Turkey: Data from the Prospective, Observational, Multicenter Survey Including 7,978 Surgical Patients.

Background: Surgical antimicrobial prophylaxis (SAP) is the peri-operative administration of antimicrobial agents. Compliance rates vary worldwide from 15% to 84.3%, with studies in Turkey not exceeding 35%. The aim of this multicenter study was to determine the rate of appropriate antibiotic class, timing, and duration as well as discharge prescriptions in Turkey. Thus, we aimed to determine the rate of full compliance with SAP procedures in our country Patients and Methods: This multicenter, prospective, observational, descriptive study was conducted in 47 hospitals from 28 provinces in seven different regions of Turkey. Patients over 18 years of age in all surgical units between June 6, 2022, and June 10, 2022, were included in the study. Results: Of the 7,978 patients included in the study, 332 were excluded from further analyses because of pre-existing infection, and SAP compliance analyses were performed on the remaining 7,646 cases. The antibiotic most commonly used for SAP was cefazolin (n = 4,701; 61.5%), followed by third-generation cephalosporins (n = 596; 7.8%). The most common time to start SAP was within 30 minutes before surgery (n = 2,252; 32.5%), followed by 30 to 60 minutes before surgery (n = 1,638; 23.6%). Surgical antimicrobial prophylaxis duration was <24 hours in 3,516 (50.7%) patients and prolonged until discharge in 1,505 (21.7%) patients. Finally, the actual proportion of patients compliant with SAP was 19% (n = 1,452) after omitting 4,458 (58.3%) patients who were prescribed oral antibiotic agents at discharge as part of a prolonged SAP. Conclusions: Surgical antimicrobial prophylaxis compliance rates are still very low in Turkey. Prolonged duration of SAP and especially high rate of antibiotic prescription at discharge are the main reasons for non-compliance with SAP.

A retrospective evaluation of COVID-19 patients treated with Tocilizumab: who should be treated?

INTRODUCTION: Tocilizumab, can be used in the treatment of COVID-19 in patients developing cytokine storms. This study retrospectively evaluated patients treated with Tocilizumab. METHODOLOGY: This study included 23 patients (17 men) admitted to the hospital and received Tocilizumab due to cytokine storms. The patients were categorized into three groups: "moderate, severe, and critical". Clinical outcomes after 7 days of hospitalization were classified as "death, disease aggravation, clinical stabilization, and clinical improvement". RESULTS: The mean age of the patients was 58±10.1 years. 52.2% of the patients were severely ill, and 47.8% were critically ill. After tocilizumab treatment, the mean lymphocyte count increased in all patients; the C-reactive protein levels dropped rapidly, except for one patient. After the first dose, the patients' fever dropped dramatically, and their oxygen support needs decreased. During the treatment, 82.6% of the patients were in the intensive care unit. At the end of the treatment, 56.5% had clinical improvement, 13% had clinical stabilization, and 4.3% had aggravation. Mortality occurred in 26.1%; 60.9% were discharged within a mean time of 19.14 ± 13.57 days after their treatment, and 18.2% of the critically ill and 91.7% of the severely ill patients recovered. CONCLUSIONS: Despite high rates of recovery and discharge after the tocilizumab treatment in the severely ill patients, more than half of the critically ill patients died. Early tocilizumab treatment resulted in a high survival rate and reduced the rates of progression to more critical states and mortality. Tocilizumab treatment should be given early in patients developing cytokine storms.

Evaluation of 170 Followed-up Cases Treated for Hydatid Disease: A Multicentre Study.

OBJECTIVE: To determine the clinical characteristics of patients with cystic echinococcosis and the diagnostic and therapeutic approaches used. METHODS: This is a multicentre, retrospective study. Patients from six centres who were diagnosed with hydatid cysts in the last five years were evaluated. RESULTS: The mean age was 45.4±17.4 years, and 54.7% were female. The most common complaints were abdominal pain, nausea and vomiting, and the most common physical examination finding was abdominal tenderness. Most patients were diagnosed within 2-6 months. Anaemia and eosinophilia were the most common laboratory findings. The liver was the most commonly involved organ (n=153, 90%). One hundred twenty-five (73.5%) patients underwent ultrasonography. The largest cyst was present in the liver at stage four, and its diameter was 160x170 mm. The rates of the negative, grey zone and positive results were 9.4%, 8.8% and 81.8%. Surgery was more common (n=72, 42.4%) than puncture, aspiration, injection, and re-aspiration treatments (n=14, 8.2%). Of the 47 patients who had a recurrence, 22 (46.8%) had a history of hydatid cyst treatment. CONCLUSION: Hydatid disease, which is endemic in our country, is diagnosed at a late stage. In terms of disease diagnosis, serological tests may be misleading. It was not possible to compare the success rates according to the treatment choices because of the lack of randomisation of stages and sizes of the lesions.
