Treatment Of Invasıve Aspergıllosıs

İnvaziv aspergilloz (İA), Aspergillus türü mantarların neden olduğu genellikle immünyetmezlikli hastalarda görülen ve yüksek mortalite ile seyreden bir enfeksiyon hastalığıdır. En sık akciğer etkilenmekle birlikte mantar vücudun diğer organlarına da yayılarak hastalık yapabilir. Tedavisinde halen vorikonazol birinci seçenek antifungaldir. Vorikonazol alamayacak ya da vorikonazole cevap vermeyen hastalarda tedavide alternatif olarak isavukonazol, itrakonazol, amfoterisin B lipid formülasyonu, itrakonazol, kaspofungin, mikafungin ve posakonazol kullanılabilir. Bu yazıda invaziv aspergilloz tedavisi gözden geçirilmiştir.Invasive aspergillosis (IA) is an infectious disease caused by Aspergillus species, is usually seen in patients with immune deficiency and has been associated with high mortality rate. IA most commonly affects the lungs, but Aspergillus can also spread throughout the body and cause infection in other organs. Voriconazole is the firstline antifungal agent in the treatment of invasive aspergillosis. Other antifungal agents including isavuconazole, lipid amphotericin formulations, itraconazole, caspofungin, micafungin, and posaconazole can be used to treat IA in patients who can not take voriconazole or who have not responded to voriconazole.

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 naive 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

Heterologous booster COVID-19 vaccination elicited potent immune responses in HCWs

The objective of our study was to evaluate the antibody responses of health care workers (HCWs) who were vaccinated with booster dose BNT162b2 6 months after 2 doses of the CoronoVac vaccine. The study included 318 HCWs vaccinated with inactive CoronaVac SARS-CoV-2 vaccine in 2 doses. Anti-spike/RBD IgG levels were measured immediately before and 1 month after the booster dose. In the sixth month after CoronaVac vaccination, the median of antibody levels of 1212.02 AU/ML, while it was 9283 AU/mL after BNT162b2 vaccination. IgG antibody titers of over 1050 AU/mL (which is equivalent to 1:80 dilution in the plaque reduction neutralization test) were detected in HCWs 15.09% and 97.8%, respectively. Our results showed that antibody titers increased 8-fold after the booster dose. We believe that the administration of the mRNA vaccine as a booster dose can provide more effective protection against COVID-19 infection, especially in individuals with risk factors.IU-Cerrahpaşa Scientific Research Projects Uni

Waning immunity to inactive SARS-CoV-2 vaccine in healthcare workers: Booster required

Aims Despite high vaccination rates, increasing case numbers continue to be reported with the identification of new variants of concern, and the issue of durability of the vaccine-induced immune response remains hot topic. Real-life data regarding time-dependent immunogenicity of inactivated COVID-19 vaccines are scarce. We aimed to investigate the changes in the antibody at the different times after the second dose of the CoronaVac vaccine. Methods The study included 175 HCWs vaccinated with inactive CoronaVac (Sinovac Life Sciences, China) SARS-CoV-2 vaccine in two doses. Anti-spike/RBD IgG levels were measured first, third, and sixth months after the second dose. Chemiluminescent microparticle immunoassay (IgG II Quant test, Abbott, USA), which is 100% compatible with plaque reduction neutralization test, was used. Results Mean age of the participants was 38 +/- 11.23 years (range between 22 and 66) of whom 119 (63.9%) were female, and 56 (32%) were male. Dramatic reductions were demonstrated in median antibody levels particularly in the infection-naive group, comprising 138 HCWs compared to those with prior history of COVID-19 infection (n = 37) (p < 0.001). There was no difference between the two groups in terms of age, gender, blood groups, BMI, and comorbid diseases. Conclusions While antibody positivity remained above 90% in the 6th month after two doses of inactivated vaccine in HCWs, the median titers of neutralizing antibodies decreased rapidly. The decrease was more rapid and significant in those with no history of prior COVID-19 infection. In this critical phase of the pandemic, where we are facing the dominance of the Omicron variant after Delta, booster doses have become vital.IU-Cerrahpasa Scientific Research Projects Uni

Self-reported antibiotic stewardship and infection control measures from 57 intensive care units: An international ID-IRI survey

We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases-International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (similar to 5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%-90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&amp;50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs' implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.

Effectiveness of fixed-dose combination of paritaprevir, ritonavir, ombitasvir, and dasabuvir in patients with chronic hepatitis C virus infection and chronic kidney diseases: real-life experiences

Introduction Both hepatitis C virus infection (HCV) and chronic kidney disease (CKD) have been comorbid illnesses with increasing morbidity and mortality. The present study was conducted to present real-life experiences about treatment of HCV and CKD with a fixed-dose combination of paritaprevir 150 mg/day, ritonavir 100 mg/day as a booster, ombitasvir 25 mg/day, and dasabuvir 250 mg twice/day, the PROD regimen. Patients and methods This was a multicenter, retrospective cohort study. Seventy-five patients with both HCV and CKD were treated with a PROD-based regimen with or without ribavirin. Fifty-three of 75 patients were on maintenance hemodialysis program. Seven patients had compensated liver cirrhosis. The patients with genotype 1a or compensated liver cirrhosis were treated with the PROD regimen and ribavirin in a dose of 200 mg every other day for 12 weeks. The patients with genotype 1b were treated with PROD for 12 weeks. The patients with genotype 4 were treated with a combination of paritaprevir, ritonavir, ombitasvir, and ribavirin 200 mg every other day. Results All patients except one were HCV-RNA negative (98.6%) at the end of treatment. One patient had decompensated after the fourth day of therapy. She stopped the treatment, and she was exitus after 2 months. Two patients died of reasons not related to the drugs 2 months after negativity of HCV-RNA. Sustained viral rate 12 weeks after treatment was found in 96% of the patients. Conclusion The PROD regimen was very effective and safe for treatment in patients with HCV and CKD who were in stages 4 and 5. Copyright (C) 2019 Wolters Kluwer Health, Inc. All rights reserved

Streptococcus pneumoniae sepsis as the initial presentation of systemic lupus erythematosus

Objective: Infections are among the most important causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE) but are rare initial presentation of the disease. Therefore, in this study, we describe a case of Streptococcus pneumoniae sepsis in a young woman with previously undiagnosed SLE. Case report: A 23-year-old female patient was admitted to our outpatient clinic complaining of high fever (40 degrees C), chills, fatigue, generalized myalgia, and cough with brown sputum for 5 days. Blood cultures grew gram-positive coccus defined as S. pneumoniae using standard procedures. Antinuclear antibody was positive at a titer of 1/1,000, and anti-double-stranded DNA was positive at 984 IU/mL. She was diagnosed with SLE. Her respiratory symptoms and pleural effusion were considered to be due to pulmonary manifestation of SLE. Conclusion: The underlying immunosuppression caused by SLE could have predisposed the patient to invasive pneumococcal disease. It may also occur as a primary presenting feature, although a rare condition

COVID-19 and Plasmodium ovale Malaria: A Rare Case of Co-Infection

The COVID-19 pandemic continues to be a major health problem worldwide. Timely diagnosis of co-infections mimicking COVID-19, such as malaria, might be challenging particularly in non-endemic areas.
