Background Chronic kidney disease (CKD) and immunosuppression, such as in renal transplantation (RT), stand as one of the established potential risk factors for severe coronavirus disease 2019 (COVID-19). Case morbidity and mortality rates for any type of infection have always been much higher in CKD, haemodialysis (HD) and RT patients than in the general population. A large study comparing COVID-19 outcome in moderate to advanced CKD (Stages 3–5), HD and RT patients with a control group of patients is still lacking. Methods We conducted a multicentre, retrospective, observational study, involving hospitalized adult patients with COVID-19 from 47 centres in Turkey. Patients with CKD Stages 3–5, chronic HD and RT were compared with patients who had COVID-19 but no kidney disease. Demographics, comorbidities, medications, laboratory tests, COVID-19 treatments and outcome [in-hospital mortality and combined in-hospital outcome mortality or admission to the intensive care unit (ICU)] were compared. Results A total of 1210 patients were included [median age, 61 (quartile 1–quartile 3 48–71) years, female 551 (45.5%)] composed of four groups: control (n = 450), HD (n = 390), RT (n = 81) and CKD (n = 289). The ICU admission rate was 266/1210 (22.0%). A total of 172/1210 (14.2%) patients died. The ICU admission and in-hospital mortality rates in the CKD group [114/289 (39.4%); 95% confidence interval (CI) 33.9–45.2; and 82/289 (28.4%); 95% CI 23.9–34.5)] were significantly higher than the other groups: HD = 99/390 (25.4%; 95% CI 21.3–29.9; P < 0.001) and 63/390 (16.2%; 95% CI 13.0–20.4; P < 0.001); RT = 17/81 (21.0%; 95% CI 13.2–30.8; P = 0.002) and 9/81 (11.1%; 95% CI 5.7–19.5; P = 0.001); and control = 36/450 (8.0%; 95% CI 5.8–10.8; P < 0.001) and 18/450 (4%; 95% CI 2.5–6.2; P < 0.001). Adjusted mortality and adjusted combined outcomes in CKD group and HD groups were significantly higher than the control group [hazard ratio (HR) (95% CI) CKD: 2.88 (1.52–5.44); P = 0.001; 2.44 (1.35–4.40); P = 0.003; HD: 2.32 (1.21–4.46); P = 0.011; 2.25 (1.23–4.12); P = 0.008), respectively], but these were not significantly different in the RT from in the control group [HR (95% CI) 1.89 (0.76–4.72); P = 0.169; 1.87 (0.81–4.28); P = 0.138, respectively]. Conclusions Hospitalized COVID-19 patients with CKDs, including Stages 3–5 CKD, HD and RT, have significantly higher mortality than patients without kidney disease. Stages 3–5 CKD patients have an in-hospital mortality rate as much as HD patients, which may be in part because of similar age and comorbidity burden. We were unable to assess if RT patients were or were not at increased risk for in-hospital mortality because of the relatively small sample size of the RT patients in this study.
Background: The combination therapies recommended by the World Health Organization for treatment of brucellosis are doxycycline plus rifampicin or doxycycline plus streptomycin. Although highly successful results have been obtained with these two regimens, relapse rates as high as 14.4%. The most effective and the least toxic chemotherapy for human brucellosis is still undetermined. The aim of the present study was to investigate the efficacy, adverse effects and cost of ofloxacin plus rifampicin therapy, and doxycycline plus rifampicin therapy and evaluate in the treatment of brucellosis.
A total of 227 subjects (112 were male and 115 female), who were residents of the rural region of Duzce, were examined for dermatomycosis. A total of 120 samples (47 nail fragments, 73 skin scales) were collected from 81 patients for mycological analysis on the basis of the results of clinical evaluation. All specimens collected were analysed by direct microscopy and culture. Positive results were detected in the cultures of 53 (44.1%) of the 120 samples. About 46 (86.7%) samples also presented positive results in direct microscopy. In the cases of seven samples positive results were found in culture and negative results with direct microscopy. Both culture and direct microscopy presented negative results in 67 (55.8%) samples. The most frequently isolated aetiological agents were 33 Trichophyton rubrum (62.2%), and nine T. mentagrophytes (16.9%). In conclusion, traditional and religious habits such as cohabitation and performing ritual ablutions may affect the prevalence of dermatophyte infections. The performance of ritual ablutions is not in itself a risk factor for acquiring dermatophyte infection; rather it is not drying the extremities after ablutions, that is the main risk factor for this group. Tinea capitis was not found in any of the subjects in spite of the fact that it is one of the most common infectious conditions in children. This is the first paper to report the prevalence of fungal infections in Duzce, a western Black Sea region of Turkey.
PurposeWe describe the epidemiological and clinical characteristics and the efficacy of a delayed initiation to therapy in an oropharyngeal tularemia outbreak in Duzce, Turkey.Materials and MethodsBetween March and June 2000, 22 patients with tularemia were diagnosed by microagglutination tests.ResultsOropharyngeal and ulceroglandular forms of the disease were discovered. Most of the cases were oropharyngeal (19 cases). The most common symptoms were sore throat (95.4%) and fever (90.9%). Lymphadenopathy (95.4%) and pharyngeal hyperemia (81.8%) were usually observed signs. The lymphadenopathies were localized especially in the left cervical region (66.7%), a finding that has not been previously reported in the literature. The time between the onset of the symptoms and diagnosis was 40.7 ± 22.8 (10 - 90) days. The patients were treated with streptomycin plus doxycycline and ciprofloxacin. The patients' recoveries took up to 120 days.ConclusionThis report describes the first outbreak of tularemia in northwest Turkey. Tularemia may occur in any region where appropriate epidemiological conditions are found and should be kept in mind for differential diagnosis in oropharyngeal symptoms. Late initiation of therapy may delay complete recovery. In this outbreak, cervical lymph nodes predominantly localized on the 1eft side were found, which had not been previously reported.
The aim of the study was to investigate the prevalance of enterically transmitted hepatitis among children living in post-earthquake camps, and to assess the efficacy of the measurements during and after the disaster in Düzce and Golyaka. In the second half of 1999, North-western Turkey, was struck by two massive earthquakes in less than 3 months. The first, on 17 August 1999, involving Golyaka, was struck, measuring between 7.4 and 7.8 on the Richter scale. Irregularity about providing clean water and necessary sanitary facilities were observed after the first earthquake because of confusion. The second quake, on 12 November 1999, which rated 7.2 on the Richter scale, shook Düzce. Necessary precautions were applied rapidly at the second quake about shelter, clean drinking water, food and control of distribution of the aids by government and civil aid organisations. Anti-HEV(IgG) and anti-HAV(IgG) antibodies were determined in 476 sera of the children who was living in six camps. HAV prevalence of the children who were living in Düzce and Golyaka temporary houses was 44.4 and 68.8% respectively, OR: 0.37, CI 95%: 0.22-0.61, p = 0.0005. HEV prevalence of the children was 4.7 and 17.2% respectively, OR: 0.24, CI 95%: 0.11-0.51, p = 0.0007. In conclusion, HAV and HEV prevalence of children were lower than that in endemic areas but higher than that in developed countries. This study has pointed out the importance of providing urgent need of the sufficient sanitary facilities after disasters for preventing or reducing the incidence of enterically transmitted hepatitis, especially in the regions which were at risk for various disasters. Essential precautions such as providing clean water and food supply must be taken and an emergency action plan for preventing the infectious disease must be prepared before disasters such as earthquakes.
Objective: To compare alcohol-based hand rubbing with hand washing using antimicrobial soap regarding antimicrobial efficacy and compliance with routine practice in hospital and intensive care units. Subjects and Methods: From February to June 2003, 35 nurses were randomly selected from a nursing staff of 141 and divided into two groups: hand rubbing and hand washing groups. Hand cultures were obtained before and after health care procedures. The nurses were observed on days 1, 7 and 14 of the study, in order to determine compliance and efficacy of the hand hygiene methods. Results: A total of 368 routine patient care activities were observed during the study period. Hand rubbing with alcohol-based solutions significantly reduced the bacterial contamination of the hands of the nurses more than hand washing with an antimicrobial soap (54 and 27%, respectively; p < 0.01). Compliance was also better in the hand rubbing group than in the hand washing group (72.5 and 15.4%, respectively; p < 0.001). Compliance with hand rubbing was markedly lower among the nurses who had experience of more than 3 years in hospital practice. Both hand rubbing and hand washing compliance were poorer among nurses working inintensive care units than among nurses working in the other hospital wards. Generally, after taking off gloves, nurses preferred hand washing to hand rubbing. Conclusion: These data indicate that alcohol-based hand rubbing reduces mean bacterial counts on the hands of nurses more effectively than hand washing with antimicrobial soaps, and compliance rates with hand rubbing were also higher than with hand washing. Nevertheless, the compliance with hand rubbing was markedly lower in more experienced nurses.
Background Acute kidney injury (AKI) is common in coronavirus disease-2019 (COVID-19) and the severity of AKI is linked to adverse outcomes. In this study, we investigated the factors associated with in-hospital outcomes among hospitalized patients with COVID-19 and AKI. Methods In this multicenter retrospective observational study, we evaluated the characteristics and in-hospital renal and patient outcomes of 578 patients with confirmed COVID-19 and AKI. Data were collected from 34 hospitals in Turkey from March 11 to June 30, 2020. AKI definition and staging were based on the Kidney Disease Improving Global Outcomes criteria. Patients with end-stage kidney disease or with a kidney transplant were excluded. Renal outcomes were identified only in discharged patients. Results The median age of the patients was 69 years, and 60.9% were males. The most frequent comorbid conditions were hypertension (70.5%), diabetes mellitus (43.8%), and chronic kidney disease (CKD) (37.6%). The proportions of AKI stages 1, 2, and 3 were 54.0%, 24.7%, and 21.3%, respectively. 291 patients (50.3%) were admitted to the intensive care unit. Renal improvement was complete in 81.7% and partial in 17.2% of the patients who were discharged. Renal outcomes were worse in patients with AKI stage 3 or baseline CKD. The overall in-hospital mortality in patients with AKI was 38.9%. In-hospital mortality rate was not different in patients with preexisting non-dialysis CKD compared to patients without CKD (34.4 versus 34.0%, p = 0.924). By multivariate Cox regression analysis, age (hazard ratio [HR] [95% confidence interval (95%CI)]: 1.01 [1.0–1.03], p = 0.035], male gender (HR [95%CI]: 1.47 [1.04–2.09], p = 0.029), diabetes mellitus (HR [95%CI]: 1.51 [1.06–2.17], p = 0.022) and cerebrovascular disease (HR [95%CI]: 1.82 [1.08–3.07], p = 0.023), serum lactate dehydrogenase (greater than two-fold increase) (HR [95%CI]: 1.55 [1.05–2.30], p = 0.027) and AKI stage 2 (HR [95%CI]: 1.98 [1.25–3.14], p = 0.003) and stage 3 (HR [95%CI]: 2.25 [1.44–3.51], p = 0.0001) were independent predictors of in-hospital mortality. Conclusions Advanced-stage AKI is associated with extremely high mortality among hospitalized COVID-19 patients. Age, male gender, comorbidities, which are risk factors for mortality in patients with COVID-19 in the general population, are also related to in-hospital mortality in patients with AKI. However, preexisting non-dialysis CKD did not increase in-hospital mortality rate among AKI patients. Renal problems continue in a significant portion of the patients who were discharged.
Increased serum ferritin levels may suggest a significant role of hemophagocytosis in the pathogenesis of CCHF and may be a useful marker for diagnosis, disease activity, and prognosis.
