Effectiveness of Plasmapheresis Treatment in the Treatment of Patients with COVID-19 Disease.

Background: According to the World Health Organization, COVID-19 management focuses primarily on infection prevention, case management, case monitoring, and supportive care. However, due to the lack of evidence, no specific anti-SARS-CoV-2 treatment is recommended. This study aimed to evaluate the effectiveness of plasmapheresis treatment in COVID-19 patients with symptoms of pulmonary involvement on the computed tomography (CT) of the lung. Methods: In 2021, an experimental study in critically ill patients admitted to the COVID-19 ward in the Hazrat-e Rasool hospital diagnosed with COVID-19 was conducted in the second phase (pilot study). The diagnosis was confirmed according to clinical signs, CT scan of the lung, and the Polymerase chain reaction (PCR) test. All patients received the usual treatments for COVID-19 disease and underwent plasmapheresis at a dose of 40 cc/kg daily up to 4 doses. All patients were observed for 24 hours for complications of plasmapheresis treatment and simultaneously for symptoms of COVID-19, after which only routine care measures were performed. The next day and 2 weeks after resumption of the treatment, patients experienced COVID-19 symptoms, including shortness of breath, cough, and fever. Blood oxygen saturation, and treatment results were evaluated. Qualitative and rank variables were described using absolute and relative frequencies and quantitative parametric variables were used using mean and confidence interval. Frequencies were compared in groups using the chi-square test. All tests were performed in 2 directions and P > 0.05 was considered statistically significant. Results: Of the 120 patients studied, 79 (65.8%) were men and 41 (34.2%) were women. The mean age was 60.30 ± 15.61 years (22-95 years). The mean hospital stay was 12.89 days ± 7.25 days (2-38 days). Increased blood oxygen saturation levels in patients had an increasing trend. Inflammatory indices had a downward trend in patients. The frequency of plasmapheresis had no significant effect on reducing the downward trend of inflammatory markers. The greatest reduction occurred in the first plasmapheresis. Conclusion: Finally, according to the findings, plasmapheresis is one of the appropriate treatments to improve patients' symptoms and reduce cytokine storm. Recovered patients had lower levels of inflammatory markers than those who died.

Spontaneous pneumothorax and pneumomediastinum in patients with COVID-19: A case series from Iran.

Here, we report six cases of spontaneous pneumothorax and pneumomediastinitis in patients with COVID-19 in Iran, which were treated with different drugs such as hydroxychloroquine, sofosbuvir, atazanavir, and remdesivir as antiviral agents. Despite the differences in the type of drugs, pneumothorax occurred in all patients.

The association between sleep quality, health status and disability due to breathlessness in chronic obstructive pulmonary disease patients.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) increases susceptibility to sleep disturbances. This study aimed to evaluate the association between COPD severity criteria with sleep quality. METHODS: One hundred fifty-eight patients in Rasul Akram Hospital of Iran University of Medical Sciences, Tehran, Iran, from April 2019 to March 2021 diagnosed with COPD were examined using the Pittsburgh Sleep Quality Index (PSQI), COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnoea scale, spirometry and pulse oximetry. RESULTS: Of 158 subjects, 125 patients were male (79%), and 33 were female (21%). The mean subject's age and FEV1/FVC ratio were 62.6 ± 11.5 and 65.6 ± 14.9%, respectively. The mean CAT scoring and Spo2 saturation reported 16.2 ± 7 and 91.5 ± 10.8%, respectively. The mean PSQI score was 8.2 ± 3.8. The association between PSQI score with FEV1 and FEV1/FVC ratio was not statistically significant (p = 0.64 and 0.58, respectively), whereas the association between PSQI scores with CAT score (p Ë‚ 0.0001, r2  = 0.51) and dyspnoea severity (p Ë‚ 0.0001, r2  = 0.29) were statistically significant. The patients with higher CAT score demonstrated poor sleep quality, particularly in longer sleep latency (p = 0.001, r2  = 0.056), bad subjective sleep quality (p Ë‚ 0.0001, r2  = 0.286), lower sleep efficiency (p = 0.002, r2  = 0.077), higher sleep disturbance (p Ë‚ 0.0001, r2  = 0.225), daytime dysfunction (p Ë‚ 0.0001, r2  = 0.259) and sleep medication intake times a week (p = 0.01, r2  = 0.069). Dyspnoea severity was attributed to bad subjective sleep quality (p Ë‚ 0.0001, r2  = 0.069), higher sleep disturbances (p = 0.005, r2  = 0.08), and daytime dysfunction (p Ë‚ 0.0001, r2  = 0.108). CONCLUSION: The PSQI has a significant association with the CAT and mMRC for COPD patients and is linked to the disease's severity.

Renal failure and lung hemorrhage as a presentation of COVID-19 infection, a case report.

The concurrent involvement of the lung and kidneys happens in COVID-19 infection. The patient's respiratory symptoms resolved after hemodialysis. This finding raises the question that if hemodialysis can have a role in the treatment of COVID-19.

Lung abscess as a complication of COVID-19 infection, a case report.

To our knowledge, no previous studies have reported lung abscess as a complication of COVID-19 infection. It is essential to follow-up with the patients after discharge for such complications, especially if they are symptomatic.

Bronchial Angioembolization for Management of Hemoptysis Due to Pulmonary Tuberculosis.

BACKGROUND: The study aimed to evaluate the effectiveness and safety of BAE in TB patient with massive hemoptysis and evaluate the recurrence rate of hemoptysis after BAE. MATERIALS AND METHODS: In this prospective study, 68 patients with moderate and severe hemoptysis due to active or old tuberculosis who underwent bronchial arteriography were included. CXR and CT scan were performed in all patients. Selective and nonselective bronchial artery angiography was performed in all patient and 62 patients underwent embolization. RESULTS: Thirty-two patients (47.1%) had active TB and 36 patients (52.9%) had inactive TB (post-tuberculosis sequelae). Abnormality was detected in a single vessel in 30 (44.1%) patients, in two vessels in 23 (33.8%) and in more than two vessels in 13 (19.1%) patients. Embolization was performed in 62 patients and overall 95 abnormal arteries were embolized. Hemoptysis control rate was 82.3% at one month, 73.5% at three months, 69.1 % at 6 months, 63.2% at one year and 60.3% after two years. CONCLUSION: No major complication occurred as a result of BAE procedures. BAE is a safe and effective method for the management of hemoptysis in patient with tuberculosis. Only 20.6% of the patients need to repeat BAE during 2 years of follow up.

Neuropsychiatric manifestations of COVID-19 can be clustered in three distinct symptom categories.

Several studies have reported clinical manifestations of the new coronavirus disease. However, few studies have systematically evaluated the neuropsychiatric complications of COVID-19. We reviewed the medical records of 201 patients with confirmed COVID-19 (52 outpatients and 149 inpatients) that were treated in a large referral center in Tehran, Iran from March 2019 to May 2020. We used clustering approach to categorize clinical symptoms. One hundred and fifty-one patients showed at least one neuropsychiatric symptom. Limb force reductions, headache followed by anosmia, hypogeusia were among the most common neuropsychiatric symptoms in COVID-19 patients. Hierarchical clustering analysis showed that neuropsychiatric symptoms group together in three distinct groups: anosmia and hypogeusia; dizziness, headache, and limb force reduction; photophobia, mental state change, hallucination, vision and speech problem, seizure, stroke, and balance disturbance. Three non-neuropsychiatric cluster of symptoms included diarrhea and nausea; cough and dyspnea; and fever and weakness. Neuropsychiatric presentations are very prevalent and heterogeneous in patients with coronavirus 2 infection and these heterogeneous presentations may be originating from different underlying mechanisms. Anosmia and hypogeusia seem to be distinct from more general constitutional-like and more specific neuropsychiatric symptoms. Skeletal muscular manifestations might be a constitutional or a neuropsychiatric symptom.

Evolution and resolution of brain involvement associated with SARS- CoV2 infection: A close Clinical - Paraclinical follow up study of a case.

The new severe acute respiratory syndrome- coronavirus 2 is reported to affect the nervous system. Among the reports of the various neurological manifestations, there are a few documented specific processes to explain the neurological signs. We report a para-infectious encephalitis patient with clinical, laboratory, and imaging findings during evolution and convalescence phase of coronavirus infection. This comprehensive overview can illuminate the natural history of similar cases. As the two previously reported cases of encephalitis associated with this virus were not widely discussed regarding the treatment, we share our successful approach and add some recommendations about this new and scarce entity.

Applying Wells score to inconclusive perfusion only modified PIOPED II (Prospective Investigation of Pulmonary Embolism Diagnosis II) readings in order to optimize the lung scintigraphy diagnostic yield in acute pulmonary embolism detection.

OBJECTIVE: When using perfusion only modified PIOPED II criteria for PE detection, generated non-diagnostic scans are found to be the main diagnostic restriction. The objective of current study is to identify the role of Wells criteria added to inconclusive readings with the intent of enhancing the lung scintigraphy diagnostic yield. METHODS: CTPA was performed in 34 suspected PE patients with inconclusive lung scintigraphy. They also were evaluated by Wells score and classified as low, intermediate and high probability. Overall prevalence and the rate of PE for each probability were calculated. Furthermore, NPV for scores < 2 and PPV for scores > 6 were computed. RESULTS: Having a mean age of 59.75 ± 17.38 years, 7 (20.6%), 23 (67.6%) and 4 (11.8%) of cases had total criteria point count < 2, 2-6 and > 6, respectively. Using CTPA, 5 patients (14.7%) were diagnosed with PE. None of the patients with scores < 2 had PE with an associated NVP of 100%. Patients with scores 2-6 had a PE rate of 4.3% and 100% of patients with scores > 6 were diagnosed with PE, implying that the PPV of scores > 6 was 100%. CONCLUSION: Adding Wells score to non-diagnostic scans allowed identification of PE to be done reliably, and provided further insight into how lung scintigraphy in conjunction with clinical assessment is a practical strategy not only for the patients unfit for performing CTPA but also in all the patients referred for PE evaluation.

Parkinsonism management issues in a patient with exhausted subthalamic deep brain stimulation battery, stricken by severe acute respiratory syndrome coronavirus 2.

Background: Nowadays, many neurological conditions, including Parkinson's disease (PD), are treated with deep brain stimulation (DBS). Life-threatening consequences can occur from DBS hardware failure or sudden implantable pulse generator (IPG) battery depletion. This issue may potentially worsen in concomitance with medical or infectious conditions, requiring stronger emergency management. Methods: We present here a 58 year-old PD patient with DBS, whose IPG replacement surgery was complicated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and we report management of this patient along with recommendations for patients with similar situation. Results: As the newly-emerged coronavirus disease 2019 (COVID-19) is now announced to be pandemic, new protocols and specific measures for each individual group of patients with chronic diseases seem obligatory. Regarding our recent experience with a patient suffering from PD, on DBS treatment, who needed hospitalization, we felt useful to share our experience as a recommended protocol for similar patients in the time of current pandemic. Conclusion: Close monitoring of laboratory and clinical signs should be warranted in patients with PD awaiting IPG replacement in order to be prepared in these novel conditions that may precipitate an akinetic crisis/dystonic storm and to prevent life-threatening complications during the current pandemic.

Outcomes and Complications of Bronchial Angioembolization in Patients with Massive Hemoptysis.

BACKGROUND: Massive hemoptysis is a potentially life threatening medical condition and one major problem for both patients and physicians. Choosing the appropriate treatment for the patients is crucial in order to decrease the complications and increase the success rate. Hence, in this study the outcomes and complications of bronchial angioembolization (BAE) were determined in patients with massive hemoptysis. MATERIALS AND METHODS: In this prospective cohort, 189 consecutive patients with moderate and severe hemoptysis who had referred to two large cardiovascular centers were enrolled. The Chest X Ray, CT Scan, Fiberoptic Bronchoscopy, Selective and Nonselective Bronchial Angiography were performed in patients. The outcomes with 20-month follow-up were compared. RESULTS: The immediate success rate was 97.3%. In 79.7% there were no complications. Temporary chest pain, subintimal dissection, temporary dysphagia, and pancreatitis were seen in 12.3, 2.4, 5.1, and 0.5%, respectively, without any major complication. The in-hospital mortality rate was 1.1% and mortality during 20-month follow-up was 9.6%, and recurrence rate was 28.3% on total. CONCLUSION: Our case series showed that BAE is a safe and effective method in treating patients with hemoptysis. Compared to surgery, the procedure is faster and less invasive and might be used both as first line or bridging therapy. Importantly, no major complications have been detected.
