A fatal rabies case and experiences of a mass post exposure prophylaxis among healthcare workers.

We aimed to monitor the adverse effects (AE) and efficacy of post exposure prophylaxis (PEP) in health care workers (HCWs) exposed to a rabies patient. In this study 109 HCWs and eight household contacts were PEP candidates. Contact persons without infection control precautions were in Group I (high risk-82 cases). HCWs indirectly exposed to environmental surfaces were classified in Group II (low risk-35 cases). PEP schedule was rabies vaccine (RBV) + equine rabies immunoglobulin (eRIG) in Group I and only RBV in Group II. Local and systemic AE were observed in all cases. Efficacy of post exposure prophylaxis (PEP) was determined by rabies development in a six month follow-up. 585 doses of RBV have been used in 117 cases and eRIG has been used in 82 cases. 32 Nurses (39%); 22 emergency medicine technicians (26.8%); 12 doctors (14%); six laboratory technicians (0.07%); six radiology technicians (0.07%); four cleaners (0.05%) were in Group I (82 cases), respectively. One doctor, laboratory technician, nurse and radiology technician (0.02%); two emergency medicine technicians (0.04%) and nine cleaners (25.7%) were in Group II (35 cases), respectively. Routes of transmission were blood in five (0.06%); saliva in 14 (17%); sweat in 50 (61%); CSF/serum in five (0.06%); sexual intercourse in one (0.01%); personal equipment in seven (0.09%) in Group I, respectively. Indirect contact was the only route in Group II. The most common local and systemic AE were seen in Group I; pain at injection side (19 cases) and fever (13 cases). Both of them showed statistically significant difference (P<0.05). Allergic rash has been seen at only one case. PEP failed in one case where the possible exposure way was sexual intercourse. PEP is the safest way to prevent rabies. Infection control precautions were still not enough applied. eRIGs are also safe and have rare AE.

Treatment of ventilator-associated pneumonia (VAP) caused by Acinetobacter: results of prospective and multicenter ID-IRI study.

Ventilator-associated pneumonia (VAP) due to Acinetobacter spp. is one of the most common infections in the intensive care unit. Hence, we performed this prospective-observational multicenter study, and described the course and outcome of the disease. This study was performed in 24 centers between January 06, 2014, and December 02, 2016. The patients were evaluated at time of pneumonia diagnosis, when culture results were available, and at 72 h, at the 7th day, and finally at the 28th day of follow-up. Patients with coexistent infections were excluded and only those with a first VAP episode were enrolled. Logistic regression analysis was performed. A total of 177 patients were included; empiric antimicrobial therapy was appropriate (when the patient received at least one antibiotic that the infecting strain was ultimately shown to be susceptible) in only 69 (39%) patients. During the 28-day period, antibiotics were modified for side effects in 27 (15.2%) patients and renal dose adjustment was made in 38 (21.5%). Ultimately, 89 (50.3%) patients died. Predictors of mortality were creatinine level (OR, 1.84 (95% CI 1.279-2.657); p = 0.001), fever (OR, 0.663 (95% CI 0.454-0.967); p = 0.033), malignancy (OR, 7.095 (95% CI 2.142-23.500); p = 0.001), congestive heart failure (OR, 2.341 (95% CI 1.046-5.239); p = 0.038), appropriate empiric antimicrobial treatment (OR, 0.445 (95% CI 0.216-0.914); p = 0.027), and surgery in the last month (OR, 0.137 (95% CI 0.037-0.499); p = 0.003). Appropriate empiric antimicrobial treatment in VAP due to Acinetobacter spp. was associated with survival while renal injury and comorbid conditions increased mortality. Hence, early diagnosis and appropriate antibiotic therapy remain crucial to improve outcomes.

A novel id-iri score: development and internal validation of the multivariable community acquired sepsis clinical risk prediction model.

We aimed to develop a scoring system for predicting in-hospital mortality of community-acquired (CA) sepsis patients. This was a prospective, observational multicenter study performed to analyze CA sepsis among adult patients through ID-IRI (Infectious Diseases International Research Initiative) at 32 centers in 10 countries between December 1, 2015, and May 15, 2016. After baseline evaluation, we used univariate analysis at the second and logistic regression analysis at the third phase. In this prospective observational study, data of 373 cases with CA sepsis or septic shock were submitted from 32 referral centers in 10 countries. The median age was 68 (51-77) years, and 174 (46,6%) of the patients were females. The median hospitalization time of the patients was 15 (10-21) days. Overall mortality rate due to CA sepsis was 17.7% (n = 66). The possible predictors which have strong correlation and the variables that cause collinearity are acute oliguria, altered consciousness, persistent hypotension, fever, serum creatinine, age, and serum total protein. CAS (%) is a new scoring system and works in accordance with the parameters in third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). The system has yielded successful results in terms of predicting mortality in CA sepsis patients.

The diagnostic utility of the "Thwaites' system" and "lancet consensus scoring system" in tuberculous vs. non-tuberculous subacute and chronic meningitis: multicenter analysis of 395 adult patients.

BACKGROUND: Tuberculous meningitis (TBM) represents a diagnostic and management challenge to clinicians. The "Thwaites' system" and "Lancet consensus scoring system" are utilized to differentiate TBM from bacterial meningitis but their utility in subacute and chronic meningitis where TBM is an important consideration is unknown. METHODS: A multicenter retrospective study of adults with subacute and chronic meningitis, defined by symptoms greater than 5 days and less than 30 days for subacute meningitis (SAM) and greater than 30 days for chronic meningitis (CM). The "Thwaites' system" and "Lancet consensus scoring system" scores and the diagnostic accuracy by sensitivity, specificity, and area under the curve of receiver operating curve (AUC-ROC) were calculated. The "Thwaites' system" and "Lancet consensus scoring system" suggest a high probability of TBM with scores ≤4, and with scores of ≥12, respectively. RESULTS: A total of 395 patients were identified; 313 (79.2%) had subacute and 82 (20.8%) with chronic meningitis. Patients with chronic meningitis were more likely caused by tuberculosis and had higher rates of HIV infection (P < 0.001). A total of 162 patients with TBM and 233 patients with non-TBM had unknown (140, 60.1%), fungal (41, 17.6%), viral (29, 12.4%), miscellaneous (16, 6.7%), and bacterial (7, 3.0%) etiologies. TMB patients were older and presented with lower Glasgow coma scores, lower CSF glucose and higher CSF protein (P < 0.001). Both criteria were able to distinguish TBM from bacterial meningitis; only the Lancet score was able to differentiate TBM from fungal, viral, and unknown etiologies even though significant overlap occurred between the etiologies (P < .001). Both criteria showed poor diagnostic accuracy to distinguish TBM from non-TBM etiologies (AUC-ROC was <. 5), but Lancet consensus scoring system was fair in diagnosing TBM (AUC-ROC was .738), sensitivity of 50%, and specificity of 89.3%. CONCLUSION: Both criteria can be helpful in distinguishing TBM from bacterial meningitis, but only the Lancet consensus scoring system can help differentiate TBM from meningitis caused by fungal, viral and unknown etiologies even though significant overlap occurs and the overall diagnostic accuracy of both criteria were either poor or fair.

Brucellosis in pregnancy: results of multicenter ID-IRI study.

Brucellosis in pregnant women is reported to be associated with obstetric complications (OCs), and adequate data for human brucellosis during pregnancy are largely lacking. We performed this multicenter retrospective cross-sectional study to evaluate the epidemiology, clinical course, treatment responses, and outcomes of brucellosis among pregnant women. The study period comprised a 14-year period from January 2002 to December 2015. All consecutive pregnant women diagnosed with brucellosis in 23 participating hospitals were included. Epidemiological, clinical, laboratory, therapeutic, and outcome data along with the assessment data of the neonate were collected using a standardized questionnaire. Data of 242 patients were analyzed. The OC rate was 14.0% (34/242) in the cohort. Of the 242 women, 219 (90.5%) delivered at term, 3 (1.2%) had preterm delivery, 15 (6.2%) aborted, and 5 (2.1%) had intrauterine fetal demise. Seventeen (7.0%) of the newborns were considered as low birth weight. Spontaneous abortion (6.1%) was the commonest complication. There were no maternal or neonatal deaths and pertinent sequelae or complications were not detected in the newborns. Splenomegaly (p = 0.019), nausea and/or vomiting (p < 0.001), vaginal bleeding (p < 0.001), anemia (blood hemoglobin < 11 g/dL; p < 0.001), high level of serum aspartate aminotransferase (> 41 IU/L; p = 0.025), oligohydramnios on ultrasonography (p = 0.0002), history of taking medication other than Brucella treatment during pregnancy (p = 0.027), and Brucella bacteremia (p = 0.029) were the significant factors associated with OCs. We recommend that pregnant women with OC or with fever should be investigated for brucellosis if they live in or have traveled to an endemic area.

Predictors of unfavorable outcome in neurosyphilis: Multicenter ID-IRI Study.

Neurosyphilis (NS) has different clinical manifestations and can appear during any stage of syphilis. We aimed to identify the factors affecting poor outcome in NS patients. Patients with positive cerebrospinal fluid Venereal Disease Research Laboratory test, and positive serological serum treponemal or nontreponemal tests were classified as definite NS. The data of 141 patients with definite NS were submitted from 22 referral centers. Asymptomatic NS, syphilitic meningitis, meningovascular syphilis, tabes dorsalis, general paresis, and taboparesis were detected in 22 (15.6%), 67 (47.5%), 13 (9.2%), 10 (7%), 13 (9.2%), and 16 patients (11.3%), respectively. The number of HIV-positive patients was 43 (30.4%). The most common symptoms were headache (n = 55, 39%), fatigue (n = 52, 36.8%), and altered consciousness (50, 35.4%). Tabetic symptoms were detected in 28 (19.8%), paretic symptoms in 32 (22.6%), and vascular symptoms in 39 patients (27.6%). Eye involvement was detected in 19 of 80 patients (23.7%) who underwent eye examination and ear involvement was detected in eight of 25 patients (32%) who underwent ear examination. Crystallized penicillin was used in 109 (77.3%), procaine penicillin in seven (4.9%), ceftriaxone in 31 (21.9%), and doxycycline in five patients (3.5%). According to multivariate regression analysis, while headache was a protective factor in NS patients, double vision was significantly associated to poor outcome. We concluded that double vision indicated unfavorable outcome among NS patients. A high clinical suspicion is needed for the diagnosis NS. As determined in our study, the presence of headache in syphilitic patients can help in early diagnosis of central nervous system disease.

Factors affecting the first-attempt success rate of intravenous cannulation in older people.

AIMS AND OBJECTIVES: To determine the factors affecting the first-attempt success of peripheral intravenous catheter (PIVC) placement in older emergency department patients. BACKGROUND: In older patients who require intravenous treatment, establishing a PIVC as fast as possible is clinically important. DESIGN: This is a prospective, observational, descriptive study. METHODS: Using a data collection form, researchers questioned both the patient and the nurse performing the procedure in terms of patient- and operator-related factors. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines (See Supporting Information Appendix S1). RESULTS: A total of 472 patients were included in the final analyses. According to the logistic regression analysis, independent factors which affected first-attempt failure were found to be: choosing a nonupper extremity site for PIVC (OR: 4.72, 95% CI: 1.35-16.45, p-value: 0.015), history of difficult intravenous access (OR: 3.02, 95% CI: 1.72-5.29, p-value: <0.001), nurse having less than 2 years of professional experience (OR: 3.45, 95% CI: 2.00-5.97, p-value: <0.001), nonpalpable veins observed after the application of tourniquet (OR: 2.21, 95% CI: 1.10-4.41, p-value: 0.025), a moderate degree of difficulty anticipated by the nurse prior to the procedure (OR: 4.32, 95% CI: 2.31-8.08, p-value: <0.001) and a high degree of difficulty anticipated by the nurse prior to the procedure (OR: 8.41, 95% CI: 4.10-17.24, p-value: <0.001). CONCLUSION: Factors affecting first-attempt success rates in peripheral intravenous catheter placement in older emergency department patients may be listed as follows: the anticipated difficulty of the procedure rated by the nurse, previous history of a difficult intravenous cannulation, choosing a nonupper extremity site for cannulation, the level of experience of the nurse and the palpability of the vein. RELEVANCE TO CLINICAL PRACTICE: Healthcare providers should consider alternative methods in the presence of factors affecting first-attempt success in older emergency department patients.

Current status of HIV/AIDS-syphilis co-infections: a retrospective multicentre study.

OBJECTIVE: Treponema pallidum and HIV are transmitted frequently through sexual contact, these agents with epidemiological similarities co-infect the same host. The current number of HIV-infected cases in Turkey is increasing. For this reason, we aimed to reveal the characteristics of syphilis in HIV/AIDS cases. METHODS: A retrospective longitudinal cohort study was performed, patients were followed up at 24 clinics in 16 cities from all seven regions of Turkey between January 2010 to April 2018. We examined the socio-demographic characteristics, laboratory parameters and neurosyphilis association in HIV/AIDS-syphilis co-infected cases. RESULTS: Among 3,641 patients with HIV-1 infection, 291 (8%) patients were diagnosed with syphilis co-infection. Most patients were older than 25 years (92%), 96% were males, 74% were working, 23% unemployed, and 3% were students. The three highest prevalence of syphilis were in Black Sea (10.3%), Mediterranean (8.4%) and Marmara Regions (7.4%). As for sexual orientation, 46% were heterosexuals, 42% men who have sex with men (MSM), and no data available for 12%. Patients with the number of CD4+ ≤ 350 mm3 reached 46%, 17% of the patients received antiretroviral therapy and neurosyphilis association reached 9%. CONCLUSION: Although HIV/AIDS-syphilis co-infection status appeared high in heterosexuals, MSM had a moderate level increase in cases. Our results suggested syphilis co-infection in HIV/AIDS cases should be integral part of monitoring in a national sexual transmitted diseases surveillance system. However, our data may provide base for HIV/syphilis prevention and treatment efforts in the future.

Hydrocephalus and vasculitis delay therapeutic responses in tuberculous meninigitis: Results of Haydarpasa-III study.

AIMS: There is no report on the factors affecting the resolution of symptoms related to meningitis during treatment of tuberculous meningitis (TBM). Thus, we examined the factors associated with early therapeutic responses. MATERIALS AND METHODS: This multicenter study included 507 patients with microbiologically confirmed TBM. However, 94 patients eligible for the analysis were included in this study from 24 centers. Six out of 94 patients died and the statistical analysis was performed with 88 survivors. Early and late responder groups were compared in the statistical analysis. P < 0.05 were considered to show a significant difference. RESULTS: In the multivariate analysis, the presence of vasculitis (P = 0.029, OR = 10.491 [95% CI, 1.27-86.83]) was found to be significantly associated with a delayed fever response whereas hydrocephalus was associated with altered mental status for >9 days duration (P = 0.005, OR = 5.740 [95% CI, 1.68-19.57]). According to linear regression analysis, fever was significantly persisting (>7 days) in the presence of vasculitis (17.5 vs. 7, P< 0.001) and hydrocephalus (11 vs. 7, P = 0.029). Hydrocephalus was significantly associated with persisting headache (21 vs. 12, P = 0.025), delayed recovery of consciousness (19.5 vs. 7, P = 0.001), and a delay in complete recovery (21 vs. 14, P = 0.007) in the linear regression analysis. Following institution of treatment, the complaints seemed to disappear in up to 2 weeks among TBM survivors. CONCLUSIONS: In the absence of hydrocephalus or vasculitis, one week of anti-tuberculosis treatment seems to be adequate for the resolution of TBM symptoms. Hydrocephalus and vasculitis delay the resolution of TBM symptoms in response to antimycobacterial treatment.

Antituberculosis drug resistance patterns in adults with tuberculous meningitis: results of haydarpasa-iv study.

BACKGROUND: Tuberculous meningitis (TBM) caused by Mycobacterium tuberculosis resistant to antituberculosis drugs is an increasingly common clinical problem. This study aimed to evaluate drug resistance profiles of TBM isolates in adult patients in nine European countries involving 32 centers to provide insight into the empiric treatment of TBM. METHODS: Mycobacterium tuberculosis was cultured from the cerebrospinal fluid (CSF) of 142 patients and was tested for susceptibility to first-line antituberculosis drugs, streptomycin (SM), isoniazid (INH), rifampicin (RIF) and ethambutol (EMB). RESULTS: Twenty of 142 isolates (14.1 %) were resistant to at least one antituberculosis drug, and five (3.5 %) were resistant to at least INH and RIF, [multidrug resistant (MDR)]. The resistance rate was 12, 4.9, 4.2 and 3.5 % for INH, SM, EMB and RIF, respectively. The monoresistance rate was 6.3, 1.4 and 0.7 % for INH, SM and EMB respectively. There was no monoresistance to RIF. The mortality rate was 23.8 % in fully susceptible cases while it was 33.3 % for those exhibiting monoresistance to INH, and 40 % in cases with MDR-TBM. In compared to patients without resistance to any first-line drug, the relative risk of death for INH-monoresistance and MDR-TBM was 1.60 (95 % CI, 0.38-6.82) and 2.14 (95 % CI, 0:34-13:42), respectively. CONCLUSION: INH-resistance and MDR rates seemed not to be worrisome in our study. However, considering their adverse effects on treatment, rapid detection of resistance to at least INH and RIF would be most beneficial for designing anti-TB therapy. Still, empiric TBM treatment should be started immediately without waiting the drug susceptibility testing.

International Nosocomial Infection Control Consortium (INICC) national report on device-associated infection rates in 19 cities of Turkey, data summary for 2003-2012.

BACKGROUND: Device-associated healthcare-acquired infections (DA-HAI) pose a threat to patient safety, particularly in the intensive care unit (ICU). We report the results of the International Infection Control Consortium (INICC) study conducted in Turkey from August 2003 through October 2012. METHODS: A DA-HAI surveillance study in 63 adult, paediatric ICUs and neonatal ICUs (NICUs) from 29 hospitals, in 19 cities using the methods and definitions of the U.S. NHSN and INICC methods. RESULTS: We collected prospective data from 94,498 ICU patients for 647,316 bed days. Pooled DA-HAI rates for adult and paediatric ICUs were 11.1 central line-associated bloodstream infections (CLABSIs) per 1000 central line (CL)-days, 21.4 ventilator-associated pneumonias (VAPs) per 1000 mechanical ventilator (MV)-days and 7.5 catheter-associated urinary tract infections (CAUTIs) per 1000 urinary catheter-days. Pooled DA-HAI rates for NICUs were 30 CLABSIs per 1000 CL-days, and 15.8 VAPs per 1000 MV-days. Extra length of stay (LOS) in adult and paediatric ICUs was 19.4 for CLABSI, 8.7 for VAP and 10.1 for CAUTI. Extra LOS in NICUs was 13.1 for patients with CLABSI and 16.2 for patients with VAP. Extra crude mortality was 12% for CLABSI, 19.4% for VAP and 10.5% for CAUTI in ICUs, and 15.4% for CLABSI and 10.5% for VAP in NICUs. Pooled device use (DU) ratios for adult and paediatric ICUs were 0.54 for MV, 0.65 for CL and 0.88 for UC, and 0.12 for MV, and 0.09 for CL in NICUs. The CLABSI rate was 8.5 per 1,000 CL days in the Medical Surgical ICUs included in this study, which is higher than the INICC report rate of 4.9, and more than eight times higher than the NHSN rate of 0.9. Similarly, the VAP and CAUTI rates were higher compared with U.S. NHSN (22.3 vs. 1.1 for VAP; 7.9 vs. 1.2 for CAUTI) and with the INICC report (22.3 vs. 16.5 in VAP; 7.9 vs. 5.3 in CAUTI). CONCLUSIONS: DA-HAI rates and DU ratios in our ICUs were higher than those reported in the INICC global report and in the US NHSN report.

The clinical features, treatment and prognosis of neutropenic fever and Coronavirus disease 2019 results of the multicentre teos study.

This multicentre (22 centres in Turkey) retrospective cohort study aimed to assess the clinical outcomes of patients with neutropenic fever and SARS-CoV-2 positivity. Study period was 15 March 2020-15 August 2021. A total of 170 cases (58 female, aged 59 ± 15.5 years) that fulfilled the inclusion criteria were included in the study. One-month mortality rate (OMM) was 44.8%. The logistic regression analysis showed the following significant variables for the mentioned dependent variables: (i) achieving PCR negativity: receiving a maximum of 5 days of favipiravir (p = 0.005, OR 5.166, 95% CI 1.639-16.280); (ii) need for ICU: receiving glycopeptide therapy at any time during the COVID-19/FEN episode (p = 0.001, OR 6.566, 95% CI 2.137-20.172), the need for mechanical ventilation (p < 0.001, OR 62.042, 95% CI 9.528-404.011); (iii) need for mechanical ventilation: failure to recover from neutropenia (p < 0.001, OR 17.869, 95% CI 3.592-88.907), receiving tocilizumab therapy (p = 0.028, OR 32.227, 95% CI 1.469-707.053), septic shock (p = 0.001, OR 15.4 96% CI 3.164-75.897), and the need for ICU (p < 0.001, OR 91.818, 95% CI 15.360-548.873), (iv) OMM: [mechanical ventilation (p = 0.001, OR 19.041, 95% CI 3.229-112.286) and septic shock (p = 0.010, OR 5.589,95% CI 1.509-20.700)]. Although it includes a relatively limited number of patients, our findings suggest that COVID-19 and FEN are associated with significant mortality and morbidity.

Predictive Value of C-Reactive Protein to Albumin Ratio for Amputation Risk in Diabetic Foot Infection.

Diabetic foot infections are one of the complications of diabetes mellitus resulting in extremity amputation and mortality. This study aimed to examine the predictive value of the C-reactive protein (CRP) to albumin ratio (CAR) for amputation risk in diabetic foot infection. Data from 178 patients were retrospectively examined. We found the cut point value of 15.45 according to the receiver operating characteristic (ROC) curve to show the predictive value of CAR for amputation risk in the overall population. We then divided the patients into two groups low (<15.45, n = 96) and high risk (≥15.45, n = 82) according to their CAR value. Matching based on propensity scores produced 64 patients in each group and showed that the amputation rate was high in the high-risk groups (50 vs 25%, P = .003). In the multivariate analysis in the matching group, previous amputation, antibiotic therapy in the last 3 months, and CAR (Odds ratio [OR]: 1.30, 95%Confidence interval [CI]: 1.01-1.45, P < .001) were independent predictors of amputation. These parameters may be useful to predict amputation risk in these patient groups.

Lipoprotein(a): A New Intensive Care Unit Admission Predictor in Coronavirus Disease 2019 Patients.

OBJECTIVE: Endothelium-related events in patients with coronavirus disease 2019 are linked to a poor prognosis. Lipoprotein(a) plays a role in vascular endothelial cell dysfunction. This research aims to investigate whether baseline serum lipoprotein(a) levels could be a predictor for intensive care unit admission and related clinical parameters in coronavirus disease 2019 patients. MATERIAL AND METHODS: The research covers 126 patients who were hospitalized in intensive care unit or the non-intensive care unit in our hospital. This prospective cohort study was conducted from January 2021 to June 2021. The patients who were positive for severe acute respiratory syndrome coronavirus 2 according to real-time polymerase chain reaction test results were included in the study. Two groups were created according to the status of intensive care unit admission. Lipoprotein(a) was studied from blood samples taken at the time of hospital admission. RESULTS: According to the results of the first clinical evaluation, 46 patients were admitted to the intensive care unit and 80 patients were admitted to non-intensive care unit in the hospital. Patients with intensive care unit admission had significantly higher serum lipoprotein(a) levels than patients without intensive care unit admission (40.9 ng/mL and 17.4 ng/mL, P < .001, respectively). The regres- sion analysis revealed that serum lipoprotein(a) levels were independently related to intensive care unit admission (odds ratio 1.242, 95% CI 1.109-1.391, P < .001). In receiver operating characteristic curve analysis, lipoprotein(a) level ≥31.42 ng/mL had 82.6% sensitivity and 72.5% specificity in predicting intensive care unit admission. The risk of intensive care unit admission was seen to be 12.522-fold higher in cases with lipoprotein(a) level ≥31.42. CONCLUSION: Lipoprotein(a) could be used as a useful biomarker for the triage of coronavirus disease 2019 patients. Baseline serum lipoprotein(a) levels may serve as a useful prognostic biomarker in patients hospitalized for coronavirus disease 2019.

[Epidural abscess due to a Mycobacterium tuberculosis strain with primary resistance to isoniazid and ethambutol]. / Izoniazid ve Etambutole Primer Dirençli Mycobacterium tuberculosis'e Bagli Epidural Apse.

Tuberculosis is primarily characterized by pulmonary involvement, however, one third of the cases exhibit extrapulmonary tuberculosis. In this report, a case of epidural abscess due to Mycobacterium tuberculosis with primary resistance to isoniazid and ethambutol was presented. A 57-year-old male patient was admitted to emergency service with ten days history of weakness in legs, disability of walking and fever. Neurological examination revealed paraplegia of lower extremities, numbness distal to T2 disc level and hyperactivity of deep tendon reflexes indicating transverse myelitis. Laboratory findings were as follows; ESR: 74 mm/hour, CRP: 22 g/L, ALT: 42 IU/L, AST: 45 IU/L and white blood cell count 23.000/mm3 (45% polymorphonuclear leukocyte, 45% lymphocyte, 10% monocyte). Spinal magnetic resonance imaging showed a fusiform abscess localized at anterior epidural space and extending along levels of C5-6 and C6-7. The longitudinal dimension of the abscess was 3 cm. The lesion was hypointense on T1 and hyperintense on T2 weighted MRI images with prominent rim shaped contrast enhancement on contrast-enhanced T1-weighted images. At fourth day of hospitalization the patient underwent neurosurgical management. M.tuberculosis was isolated from the cultures of operation material by Mycobacteria Growth Incubator Tube system (MGIT, BBL; BD, USA) on the 12th day. The isolate was found susceptible to streptomycin and rifampisin, but resistant to isoniazid and ethambutol. The treatment was initiated with rifampicin 600 mg/day, pyrazinamid 2 g/day, ethambutol 1.5 g/day and levofloxacin 500 mg/day. At the end of second month levofloxacin 500 mg/day and rifampisin 600 mg/day combination was sustained and total treatment period was planned as nine months. As far as the national literature was considered, this was the first case of extrapulmonary tuberculosis with primary resistance to isoniazid and ethambutol.

Preadmission usage of metformin and mortality in COVID-19 patients including the post-discharge period.

BACKGROUND: The effect of preadmission metformin usage (PMU) on the mortality of coronavirus disease-2019 (COVID-19) patients with diabetes is conflicting. Most studies have focused on in-hospital mortality; however, mortality after discharge also increases in COVID-19 patients. AIMS: Examining the effect of PMU on all-cause mortality, including the post-discharge period. METHODS: Patients with diabetes who were hospitalised in 2020 due to COVID-19 were included in the study. They were divided into two groups: those with a history of metformin use (MF( +)) and those without such history (MF( -)). Propensity score matching (PSM) was performed at a ratio of 1:1 for age and sex. COX regression analyses were used to demonstrate risk factors for mortality. RESULTS: We investigated 4103 patients hospitalised for COVID-19. After excluding those without diabetes or with chronic liver/kidney disease, we included the remaining 586 patients, constituting 293 women (50%) with an overall mean age of 66 ± 11.9 years. After PSM analysis, the in-hospital and post-discharge mortality rates were higher in the MF( -) group though not significantly different. However, overall mortality was higher in the MF( -) group (51 (42.5%) vs. 35 (29.2%), p = 0.031). For overall mortality, the adjusted HR was 0.585 (95% CI: 0.371 - 0.920, p = 0.020) in the MF( +) group. CONCLUSION: PMU is associated with reducing all-cause mortality. This effect starts from the in-hospital period and becomes more significant with the post-discharge period. The main limitations were the inability to evaluate the compliance with metformin and the effects of other medications due to retrospective nature.

Prophylactic Anticoagulant Treatment Might Have an Anti-inflammatory Effect and Reduce Mortality Rates in Hospitalized COVID-19 Patients?

Objectives: COVID-19 associated coagulopathy and prophylactic anticoagulant therapy (PAT) are ongoing topics globally. Using PAT for anti-inflammatory effect may prevent thromboembolic events (TEEs). The objective of this study was to determine the anti-inflammatory effects of PAT in hospitalized COVID-19 patients. Methods: We conducted a retrospective observational study in a tertiary pandemic hospital. Patients were divided into two categories according to their PAT therapy status (PAT (+) and PAT (-)) and into three categories according to clinical features (mild: group 1; moderate: group: 2; and severe: group 3). We then evaluated laboratory parameters and clinical courses. Results: We included 662 hospitalized COVID-19 patients in this study. Enoxaparin sodium was given to all patients as PAT therapy. TEE was developed in five patients in the PAT (+) group. Pulmonary embolism developed in 3/5 patients and deep venous thrombosis in 2/5 patients. Disseminated intravascular coagulation (DIC) was detected in 54 patients in group 3. No statistically significant difference was found in 28-day mortality, development of DIC rates, intubation rates, and TEEs. Conclusions: The use of PAT in critically ill patients was not effective in reducing C-reactive protein, which is one of the biomarkers of inflammation.

Hydatid Cyst of the Spine: A Rare Case Report

Hydatid cyst is a zoonotic disease that can affect multiple organs and is difficult to diagnose and treat. Spinal hydatid cyst (SHC) is a rare hydatid cyst involvement observed in 1% of all cases. It can induce various neurological symptoms depending on the region of the involvement. Paraplegia is one of the most prevalent neurological symptoms. In this case report, a 63-year-old male patient with bilateral lower extremity paraplegia was operated on by neurosurgery and diagnosed with SHC at the level of Th 11 vertebra in the pathological examination of surgically removed materials. Thus, we aimed to emphasize the significance of pathological and microbiological examination in the differential diagnosis of spinal disorders.

Evaluation of the Hospitalized Coronavirus Disease 2019 Patients in First 3 Months of the Pandemic.

OBJECTIVE: Data about Turkish coronavirus disease 2019 patients are limited. We evaluated hospitalized coronavirus disease 2019 patients who were followed up in the first 3 months of the pandemic. MATERIAL AND METHODS: This retrospective, single-center, observational study included 415 confirmed hospitalized coronavirus disease 2019 patients. The patients were divided into groups, namely, mild, moderate, and critically ill patients. Symptoms at the time of admission, clinical, laboratory, and imaging findings were examined. RESULTS: In our study, 6.74% of coronavirus disease 2019 patients had severe disease, 59.5% were male, and the mortality rate was 11.3%. Diabetes mellitus and chronic obstructive pulmonary disease were more frequently seen in critically ill patient groups and hypertension in moderate patient groups. Anemia and aspartate aminotransferase levels were higher in non-survivors among mild coronavirus disease 2019 patients. In the moderate patients' group, aspartate aminotransferase, lactate dehydrogenase, international normalized ratio, ferritin, and D-dimer levels were higher and lymphocyte, hemoglobin levels were lower; in the critically ill patients' group, platelets were lower and uric acid levels were higher in non-survivor patients. CONCLUSION: In mild patients, anemia, lymphopenia, and increased aspartate aminotransferase levels; in moderate patients, leukopenia, anemia, and increased aspartate aminotransferase, lactate dehydrogenase, international normalized ratio, ferritin, and D-dimer levels; in the critically ill patient group, lower platelet and increased uric acid levels should be followed closely as they are mortality predictors.

Efficacy and Safety of Direct-Acting Antivirals in Elderly Patients with Chronic Hepatitis C: A Nationwide Real-Life, Observational, Multicenter Study from Turkey.

BACKGROUND: The number and proportion of elderly patients living with chronic hepatitis C are expected to increase in the coming years. We aimed to compare the real-world efficacy and safety of direct-acting antiviral treatment in elderly and younger Turkish adults infected with chronic hepatitis C. METHODS: In this multicenter prospective study, 2629 eligible chronic hepatitis C patients treated with direct-acting antivirals between April 2017 and December 2019 from 37 Turkish referral centers were divided into 2 age groups: elderly (≥65 years) and younger adults (<65 years) and their safety was compared between 2 groups in evaluable population. Then, by matching the 2 age groups for demographics and pretreatment risk factors for a non-sustained virological response, a total of 1516 patients (758 in each group) and 1244 patients (622 in each group) from the modified evaluable population and per-protocol population were included in the efficacy analysis and the efficacy was compared between age groups. RESULTS: The sustained virological response in the chronic hepatitis C patients was not affected by the age and the presence of cirrhosis both in the modified evaluable population and per-protocol population (P = .879, P = .508 for modified evaluable population and P = .058, P = .788 for per-protocol population, respectively). The results of the per-protocol analysis revealed that male gender, patients who had a prior history of hepatocellular carcinoma, patients infected with non-genotype 1 hepatitis C virus, and patients treated with sofosbuvir+ribavirin had a significantly lower sustained virological response 12 rates (P < .001, P = .047, P = .013, and P = .025, respectively). CONCLUSION: Direct-acting antivirals can be safely used to treat Turkish elderly chronic hepatitis C patients with similar favorable efficacy and safety as that in younger adults.
