The Efficacy of Daily Administration of Nebulized Heparin on the Prevention of Endotracheal Tube Blockage in Patients With Pneumonia.

Objective: Nosocomial infections pose a significant public health concern, impacting over 100 million people worldwide annually. Within this research, we investigated heparin nebulization through the endotracheal tube and its effect on preventing blockage due to clots and mucus plugs compared to normal saline.

Methods: A double-blind clinical experiment was done on a cohort of 40 pneumonia patients who were intubated and hospitalized in the intensive care unit (ICU) at Imam Khomeini Hospital in Ahvaz, Iran.

Evaluation of the effectiveness of Tadalafil on improving pulmonary function and asthma severity in severe asthmatic patients: a randomized controlled trial study.

Phosphodiesterase inhibitors elevate the levels of cyclic adenosine monophosphate and cyclic guanosine monophosphate, which have been associated with various anti-inflammatory effects that can help alleviate asthma symptoms. This study aims to assess the impact of Tadalafil, a selective phosphodiesterase inhibitor, on pulmonary function in patients with asthma. This study was a randomized, double-blind clinical trial conducted in 2021 at Imam Khomeini Hospital in Ahvaz, Iran.

Analysis of CD4, CD8, CD19, CD56-16, CD64, QuantiFERON biomarkers in exudative lymphocyte-dominant pleural effusion.

Background: There are two main causes of exudative effusion including malignancy-induced effusion and tuberculosis. Considering that in reactive ejections, such as tuberculosis-induced effusion, the role of B lymphocytes and in the malignant effusion, the role of T lymphocytes are more important, in this study we analyzed the frequency of CD4, CD8, CD19, CD56-16, CD64, QuantiFERON in the pleural and serum samples of patients with exudative lymphocytic-dominant effusion.

Methods: In total, 73 patients were enrolled in the study by exudative lymphocyte effusion, and finally, 63 patients had definite diagnoses.

Diversity of malignancies in patients with different types of inborn errors of immunity.

Genetic defects in the development, maturation, and/or function of the immune cells can lead to Inborn errors of immunity (IEI) which may predispose patients to malignancies. The overall risk for cancer in children with IEI ranges from 4 to 25% and the type of malignancy is highly dependent on the specific mutant gene underlying IEI. We investigated 3056 IEI patients registered in the Iranian national registry between the years 1999 and 2020 in this retrospective cohort study.

Investigating the effect of sildenafil on improving lung function and quality of life in the patients with severe asthma.

Introduction: Phosphodiesterase inhibitors (PDEs) increase intracellular cyclic adenosine monophosphate, which results in a wide range of anti-inflammatory effects and pathologically leads to improve asthma disease. Because no human study has surveyed the effect of PDEs on pulmonary function, except some case reports and animal researches, we decided to perform a pilot study for evaluating the effect of sildenafil (PDE5) on pulmonary function in patients with severe asthma.

Methods: This randomized controlled trials study was conducted on 20 patients with severe asthma in 2019 in Iran.

Relationship between serum procalcitonin level and chronic obstructive pulmonary disease.

Background: Differentiation of the etiologies of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and differential diagnosis of other causes of respiratory attacks in chronic obstructive pulmonary disease (COPD) patients are challenging. Serum procalcitonin (PCT) which is a biomarker of bacterial infection, but not viral infections, could possibly recognize AECOPD requiring antibiotic treatment from other etiologies of respiratory attack.

Methods: Patients aged from 40-80 years who were diagnosed with COPD according to the GOLD criteria and who referred to the Imam Khomeini Hospital of Ahvaz in 2016 were divided into two groups of exacerbated and stable COPD.
