Clinical and Laboratory Parameters for Differential Diagnosis of Necrotizing Faciitis and Cellulitis.

ObjectiveS: Necrotizing fasciitis (NF) requires surgical intervention and has high morbidity and mortality. Furthermore, it can be confusing with some skin diseases such as cellulitis. We investigated the roles of clinical and laboratory parameters at the time of admission to the hospital in the differential diagnosis of NF and cellulitis patients. Methods: Patients with cellulitis and NF located between the nipple level and the knee between January 2018 and January 2021 were included in our retrospective study. The fever, history, complete blood count results, blood biochemistry, C-reactive protein and procalcitonin values of the patients at the time of admission to the emergency department, length of hospital stay, mortality rates, and laboratory risk indicator for necrotizing fasciitis (LRINEC) scores were recorded and evaluated whether there was a difference in both patient groups. Results: A total of 55 patients, including 26 patients in the NF group and 29 patients in the cellulite group, were included in the study. It was observed that patients with NF applied to the hospital statistically earlier, had higher leukocyte, platelet and neutrophil levels, had longer hospital stays and had higher mortality numbers. Conclusion: In high leukocyte, platelet, and neutrophil levels in the case of cellulitis patients, the clinician should follow the patient's clinic course closely and keep NF in mind.

In a Real-Life Setting, Direct-Acting Antivirals to People Who Inject Drugs with Chronic Hepatitis C in Turkey.

BACKGROUND: People who inject drugs (PWID) should be treated in order to eliminate hepatitis C virus in the world. The aim of this study was to compare direct-acting antivirals treatment of hepatitis C virus for PWID and non-PWID in a real-life setting. METHODS: We performed a prospective, non-randomized, observational multicenter cohort study in 37 centers. All patients treated with direct-acting antivirals between April 1, 2017, and February 28, 2019, were included. In total, 2713 patients were included in the study among which 250 were PWID and 2463 were non-PWID. Besides patient characteristics, treatment response, follow-up, and side effects of treatment were also analyzed. RESULTS: Genotype 1a and 3 were more prevalent in PWID-infected patients (20.4% vs 9.9% and 46.8% vs 5.3%). The number of naïve patients was higher in PWID (90.7% vs 60.0%), while the number of patients with cirrhosis was higher in non-PWID (14.1% vs 3.7%). The loss of follow-up was higher in PWID (29.6% vs 13.6%). There was no difference in the sustained virologic response at 12 weeks after treatment (98.3% vs 98.4%), but the end of treatment response was lower in PWID (96.2% vs 99.0%). In addition, the rate of treatment completion was lower in PWID (74% vs 94.4%). CONCLUSION: Direct-acting antivirals were safe and effective in PWID. Primary measures should be taken to prevent the loss of follow-up and poor adherence in PWID patients in order to achieve World Health Organization's objective of eliminating viral hepatitis.

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.

Enigma of COVID-19: is "multisystem inflammatory syndrome in adults" (MIS-A) predictable?

BACKGROUND: Severe inflammation and one or more extrapulmonary organ dysfunctions have been reported and this clinical picture is defined as "multisystem inflammatory syndrome in adults" (MIS-A) in severe coronavirus disease-2019 (COVID-19). We aimed to determine the effect of LDH/lymphocyte ratio (LLR) on the development of MIS-A. METHODS: The data of 2333 patients were retrospectively analyzed. RESULTS: MIS-A rate was found to be 9.9% and MIS-A related mortality was 35.3%. LRR level above 0.24 was found to predict MIS-A development with 70% sensitivity and 65.2% specificity. The risk of MIS-A development was found to be 3.64 times higher in those with LRR levels above 0.24 compared to those with 0.24 and below. In patients with MIS-A, LRR level above 0.32 predicts mortality with 78% sensitivity and 70% specificity. CONCLUSIONS: Early detection of MIS-A with high sensitivity and specificity in a practical ratio is very important in terms new studies.

Could serum thrombocyte/lymphocyte (TLR), neutrophil/lymphocyte (NLR) and neutrophil/albumin (NAR) ratios be indicators of hospitalization and mortality in COVID-19?

Background and Objectives: Neutrophil / lymphocyte (NLR) and thrombocyte / lymphocyte ratios (TLR) are also a guiding factors in the prognostic evaluation of infectious diseases. Another parameter to determine inflammation and prognosis is albumin. This study was aimed to determine whether TLR, NLR and neutrophil / albumin ratios (NAR) are effective in predicting the severity and course of Corona Virus Disease-2019 (COVID-19). Materials and Methods: In this retrospective and cross-sectional study, a total of 1597 patients who were admitted to our hospital between 15.03.2020-1.06.2020, diagnosed with COVID-19 were evaluated. Results: In the estimation of the decision for hospitalization, TLR, NLR and NAR AUROC values were 0.596, 0.634, 0.602 for cutoff values 123.7, 2.3 and 839.5, respectively. In predicting mortality, TLR, NLR and NAR AURO sample size can be specified C values were 0.674, 0.821, 0.787 for cutoff values 168.1, 5.2 and 1303.4, respectively (p <0.001 for all). Conclusion: In our study, it was determined that TLR, NLR and NAR are independent predictors in making the decision of hospitalization and in determining the prognosis in patients who are decided to be hospitalized.

Evaluation of Intraventricular/Intrathecal Antimicrobial Therapy in the Treatment of Nosocomial Meningitis Caused by Multidrug-Resistant Gram-Negative Bacteria after Central Nervous System Surgery.

INTRODUCTION: Postoperative meningitis (POM) is an infection with high mortality and morbidity following central nervous system surgery due to trauma or tumor. Intrathecal/intraventricular (IT/IVT) antibiotic administrations have been considered as the last treatment options for multidrug-resistance (MDR) Gram-negative bacteria that do not respond to intravenous (IV) regimens. IT/IVT can bypass the blood-brain barrier, obtain a more effective antibiotic concentration in CSF, and reduce systemic side effects. We aimed to determine the characteristics of postoperative patients who were diagnosed with MDR POM during follow-up in our intensive care unit (ICU). Material and Methods. In this study, POM patients who were followed up in ICU after the central nervous system intervention between January 2016 and December 2019 and whose MDR Gram-negative bacteria were isolated from CSF were evaluated. As soon as the patients were diagnosed with POM, a catheter was inserted and treatment was started. RESULTS: Microbiological eradication was achieved in 3 ± 0.8 days with 30 mg/day amikacin treatment in POM due to K. pneumoniae and 3.7 ± 1.95 days with colistin sodium 10 mg/day treatment in POM due to A. baumannii via IT/IVT catheter. IT/IVT treatment was utilized for a median of 10 days and continued until the defined cure criteria were achieved. While cure was achieved in 6 of 14 POM cases, 8 of them were exitus. Discussion and Conclusion. To avoid the severe consequences of postoperative meningitis, acting fast and adding IT/IVT methods to parenteral administration routes by considering the distribution of MDR microorganisms within the hospital while planning effective treatment will increase the clinical success.

A new parameter in COVID-19 pandemic: initial lactate dehydrogenase (LDH)/Lymphocyte ratio for diagnosis and mortality.

BACKGROUND: COVID-19 (Coronavirus Disease-2019) is a pandemic disease, infecting more than 26.5 million people. Since there is no specific and effective treatment; early diagnosis and optimal isolation of the patient are of vital importance. Real-time polymerase chain reaction-based (RT-PCR) analyses do not achieve sufficient sensitivity in the diagnosis of the disease. METHODS: The data from 2217 patients diagnosed as COVID-19 between March 2020 and June 2020 and hospitalized or discharged with home isolation were retrospectively analyzed. Demographic data, comorbidities, PCR results, initial computed tomography (CT), laboratory values, Lactate Dehydrogenase (LDH)/Lymphocyte ratio, initial treatments and last status were recorded. The diagnostic sensitivity of LDH/Lymphocyte ratio, which is the main purpose of the study, was analyzed statistically. RESULTS: In order to test the effectiveness of LDH/Lymphocyte ratio for COVID-19 for diagnostic purposes, CT results were considered as gold standard. The area under the curve (AUC) was found to be 0.706 (p < 0.001; cut-off > 0.06) (Sensitivity: 76.4, specificity: 59.60). For the evaluation of LDH/Lymphocyte ratio in terms of survival, AUC was found to be 0.749 (p < 0.001; cut-off > 0.21) (Sensitivity: 70.59, specificity: 73.88). CONCLUSION: Studies based on radiological findings have demonstrated that CT involvement has higher sensitivity. LDH/Lymphocyte ratio was analyzed in terms of diagnosis and mortality with using specific CT involvement as gold standard method which was found to be a more sensitive due to PCR false negativity; 0.06 and 0.21 were obtained as cut off values for diagnosis and mortality.

Retrospective Evaluation of 31 Malaria Cases Hospitalized in Our Clinic Between 2012-2018

Objective: Malaria is an infection disease caused by plamodium parasite. Sporadic cases have not been observed since 2011, but imported cases still present owing to travel. In this study, we aimed to evaluate labotauary and clinical findings patients with malaria who were hospitalized and treated in our hospital. Methods: Between January 2012-November 2018, a total of 31 adult patients was evaluated retrospectively, in terms of their epidemiological, physical examination and laboratory findings, complaints, countries they traveled to, prophylaxis and treatment that they received. Data of the patients were taken from the hospital's database. Results: A total of 31 cases were diagnosed as having malaria. The causative microorganism was P. falciparum in 54.83% (17/31) of the patients, P. vivax in 32.25% (10/31), and P. falciparum-P. vivax co-infection in 12.9% (4/31) of the patients. Co-infections were excluded from the study. None of the cases had used prophylactic drugs for prevention of malaria. All of the cases suffered from chills with fever. The most frequently encountered pathologic laboratory findings were thrombocytopenia and leucopenia. Antibiotics had been initiated in 51.85% (14/27) of the patients with non-specific diagnoses. Rapid antigen test was used in 8148% (22/27) of cases. None of cases needed intensive care. Conclusion: It is important to inform persons who plan to visit malaria endemic areas about malaria and to make them take appropriate prophylaxis against malaria. Although P. falciparum which has a high mortality rate may be considered in the first plan, P. vivax, treatment of which is different due to risk of relapse, should not be overlooked.

The effect of the different treatment protocols on virological and immunological responses in patients with HIV/AIDS.

This study analyzed the differences between the virological and immunological responses in patients with HIV/AIDS subjected to different treatment protocols. The cases treated with HAART were divided into groups on the basis of treatment protocols. The groups were evaluated with respect to the differences by comparing the virological and immunological responses prior to treatment and at 12 and 24 weeks of therapy. Six different treatment protocols were applied in the treated patients. As the largest clusters, the lopinavir/ritonavir-based patient group (Group 1, n = 29) and efavirenz-based patient group (Group 2, n = 18) were compared. The mean CD4 and HIV-RNA values of Groups 1 and 2 were 184 and 243 h/µl and 422,266 and 317,684 copies/ml, respectively. At 24 weeks of treatment, the HIV-RNA levels were below detectable values in 86% and 78% of the patients in Groups 1 and 2, respectively (p > 0.001). The striking outcomes observed in this study demonstrated that the pretreatment HIV-RNA level, CD4 value, gender, age, and protease inhibitor- or non-nucleoside reverse transcriptase inhibitor-based combined treatment protocols do not cause a significant difference and that patient compliance to treatment is the most important factor associated with treatment success.

A case report: nasobiliary drainage inducing remission in benign recurrent intrahepatic cholestasis.

Benign recurrent intrahepatic cholestasis is a rare hereditary disorder characterized by recurrent episodes of cholestasis and pruritus without anatomical obstruction. Generally, medical therapy is not effective in benign recurrent intrahepatic cholestasis. Here, we report the case of a young male patient with benign recurrent intrahepatic cholestasis who presented with cholestatic jaundice and pruritus, refractory to standard therapies. He improved on treatment with temporary endoscopic nasobiliary drainage. We propose that temporary endoscopic nasobiliary drainage should be considered in cholestatic benign recurrent intrahepatic cholestasis patients. A 36-year-old male patient admitted to our outpatient clinic with the complaint of pruritus. His anamnesis revealed that he experienced the same symptoms and signs in 2006. He was hospitalized in a hepatology clinic and was thoroughly examined. Liver biopsy was performed, and he was finally diagnosed as having benign recurrent intrahepatic cholestasis. Medical therapy options all proved to be ineffective and we were able to achieve remission in this patient only with the help of nasobiliary drainage. For this patient, we tried nasobiliary drainage in addition to the standard medical therapies. He improved on nasobiliary drainage. In conclusion, we propose that temporary endoscopic biliary drainage should be considered in cholestatic benign recurrent intrahepatic cholestasis patients. We hope that this case report contributes to the topic, since only a few nasobiliary drainage case experiences have been reported to date.

Renal and suprarenal insufficiency secondary to familial Mediterranean fever associated with amyloidosis: a case report.

INTRODUCTION: Familial Mediterranean fever is an autosomal recessive disease that predominantly affects people of the Mediterranean coast. One of the most frequent complications of the disease is amyloidosis. This clinical entity is known as secondary (also called AA) amyloidosis. CASE PRESENTATION: In this report, we describe the case of a 33-year-old Turkish man with familial Mediterranean fever and chronic renal insufficiency. He was admitted to our clinic with symptoms of suprarenal insufficiency. The patient died three months later as a result of cardiac arrest. CONCLUSION: Our aim is to make a contribution to the literature by reporting a case of combined insufficiency due to the accumulation of renal and adrenal amyloid in a patient with familial Mediterranean fever, which has very rarely been described in the literature. We hope that adrenal insufficiency, which becomes fatal if not diagnosed and treated rapidly, will come to mind as easily as chronic renal failure in clinical practice.
