The COVID-19 outbreak is affecting people worldwide. Many infected patients have respiratory involvement that may progress to acute respiratory distress syndrome. This pilot study aimed to evaluate the clinical efficacy of low-dose whole-lung radiation therapy in patients with COVID-19 pneumonia. Methods and Materials: In this clinical trial, conducted in Iran, we enrolled patients with COVID-19 who were older than 60 years and hospitalized to receive supplementary oxygen for their documented pneumonia. Participants were treated with whole-lung irradiation in a single fraction of 0.5 Gy plus the national protocol for the management of COVID-19. Vital signs (including blood oxygenation and body temperature) and laboratory findings (interleukin-6 and C-reactive peptide) were recorded before and after irradiation. Results: Between May 21, 2020 and June 24, 2020, 5 patients received whole-lung irradiation. They were followed for 5 to 7 days to evaluate the response to treatment and toxicities. The clinical and paraclinical findings of 4 of the 5 patients (patient 4 worsened and died on day 3) improved on the first day of irradiation. Patient 3 opted out of the trial on the third day after irradiation. The mean time to discharge was 6 days for the other 3 patients. No acute radiation-induced toxicity was recorded. Conclusions: With a response rate of 80%, whole-lung irradiation in a single fraction of 0.5 Gy had encouraging results in oxygen-dependent patients with COVID-19 pneumonia.
Although vaccination is used to control HBV among prisoners, prevalence of HCV exposure is alarming in the prison population of Iran, especially among people who inject drugs. Eliminating viral hepatitis in Iran by 2030 requires a national commitment and rapid measures for targeting this high-risk group. Given the increased efficiency of HCV treatment in recent years, prisons provide an opportunity to access patients for treatment.
ContextHepatitis C virus (HCV) infection is a major public health issue worldwide, including Iran. The new direct-acting antiviral agents (DAAs) with high efficacy have changed the landscape of HCV treatment. This guideline provides updated recommendations for clinical management of HCV infection in Iran.Evidence AcquisitionThe recommendations of this guideline are based on international and national scientific evidences and consensus-based expert opinion. Scientific evidences were collected through a systematic review of studies that evaluated efficacy and safety of DAA regimens, using PubMed, Scopus and Web of Science. Expert opinion was based on the consensus of Iran Hepatitis Scientific Board (IHSB) in the 3rd national consensus on management of Hepatitis C in Iran, held on 22nd of July 2016.ResultsPegylated Interferon alpha (PegIFN), Ribavirin (RBV), Sofosbuvir (SOF), Ledipasvir (LDV) and Daclatasvir (DCV) are currently available in Iran. Pre-treatment assessments include HCV RNA level, HCV genotype and resistance testing, assessment of liver fibrosis, and underlying diseases. In HCV genotype 1 and 4, DCV/SOF and LDV/SOF are recommended. In HCV genotype 2, SOF plus RBV and in HCV genotype 3, DCV/SOF is recommended. Additional care for underlying diseases should be considered.ConclusionsAffordable new HCV treatment regimens are available in Iran, providing an opportunity for HCV elimination. Recommendations provided in this current national guideline can facilitate evidence-based management of HCV infection.
There are few estimates of influenza burden in the WHO Region for the Eastern Mediterranean. In this study we estimated the burden of severe acute respiratory infection (SARI) and influenza-associated SARI (F-SARI) in selected provinces of Islamic Republic of Iran, the trends of SARI and confirmed cases of influenza (F-SARI) over 12 months (seasonality), and the age groups most at risk. Using the electronic Iranian influenza surveillance system and data of cases in sentinel hospitals of 3 selected provinces, we estimated the monthly trend (seasonality) of incidence for SARI and F-SARI, overall incidence of SARI and F-SARI and their disaggregation by age with the aid using the Monte Carlo technique. The age groups most at-risk were children aged under 2 years and adults older than 50 years. و
