Risk factors for the development of interstitial lung disease following severe COVID-19 pneumonia and outcomes of systemic corticosteroid therapy: 3-month follow-up.

BACKGROUND: We aimed to evaluate the pulmonary involvement status, its related factors, and pulmonary function test (PFT) results in the first month follow-up in patients who were discharged for severe Covid-19 pneumonia, and to assess the efficacy of corticosteroid treatment on these parameters in severe pulmonary involvement patients. METHODS: We retrospectively analyzed all consecutive patients who applied to our COVID-19 follow-up clinic at the end of the first month of hospital discharge. Functional and radiological differences were compared after 3 months of corticosteroid treatment in severe pulmonary involvement group. Results We analyzed 391 patients with "pulmonary parenchymal involvement" (PPIG) and 162 patients with "normal lung radiology" (NLRG). 122 patients in the PPIG (corticosteroid-required interstitial lung disease group (CRILD)) had severe pulmonary involvement with frequent symptoms and required corticosteroid prescription. Pulmonary involvement was more common in males and elder patients (P<0.001, for both). Being smoker and elderly were associated with a higher risk-ratio in predicting to be in PPIG (OR:2.250 and OR:1.057, respectively). Smokers, male and elderly patients, and HFNO2 support during hospitalization were risk factors for being a patient with CRILD (OR:2.737, OR:4.937, OR:4.756, and OR:2.872, respectively). After a three-months of methylprednisolone medication, a good response was achieved on radiological findings and PFT results in CRILD. CONCLUSIONS: In conclusion, after severe COVID-19 pneumonia, persistent clinical symptoms and pulmonary parenchymal involvement would be inevitable in elder and smoker patients. Moreover, corticosteroid treatment in patients with severe parenchymal involvement was found to be effective in the improvement of radiological and functional parameters.

The Role of Pneumococcal Pneumonia among Community-Acquired Pneumonia in Adult Turkish Population: TurkCAP Study.

OBJECTIVE: To evaluate the rate of pneumococcal pneumonia (PP) among patients with community-acquired pneumonia (CAP) in Turkey and to investigate and compare features of PP and non-PP CAP patients. MATERIAL AND METHODS: This multicenter, non-interventional, prospective, observational study included adult CAP patients (age ≥ 18 years). Diagnosis of PP was based on the presence of at least 1 positive laboratory test result for Streptococcus pneumoniae (blood culture or sputum culture or urinary antigen test [UAT]) in patients with radiographic findings of pneumonia. RESULTS: Four hundred sixty-five patients were diagnosed with CAP, of whom 59 (12.7%) had PP. The most common comorbidity was chronic obstructive pulmonary disease (30.1%). The mean age, smoking history, presence of chronic neurological disease, and CURB-65 score were significantly higher in PP patients, when compared to non-PP patients. In PP patients, 84.8% were diagnosed based ony on the UAT. The overall rate of PP patients among CAP was calculated as 22.8% considering the UAT sensitivity ratio of 63% (95% confidence interval: 45-81). The rate of intensive care treatment was higher in PP patients (P = .007). While no PP patients were vaccinated for pneumococcus, 3.8% of the non-PP patients were vaccinated (P = .235). Antibiotic use in the preceding 48 hours was higher in the non-PP group than in the PP group (31.8% vs. 11.1%, P = .002). The CURB-65 score and the rate of patients requiring inpatient treatment according to this score were higher in the PP group. CONCLUSION: The facts that PP patients were older and required intensive care treatment more frequently as compared to non-PP patients underline the burden of PP.

Atrial fibrillation, an obscured cause of pulmonary embolism can be revealed by adding to Wells criteria.

Among the various clinical scoring methods used for the prediagnosis of pulmonary embolism (PE), Wells criteria is the most common. It relies on the findings and story of deep venous thrombosis (DVT), PE and malignancy. It is known that atrial fibrillation (AF) is a risk factor for PE like as DVT or malignancy. We aimed to evaluate the possibility of diagnosing more patients with PE by including AF in the Wells criteria. This prospective study included 250 patients admitted to the emergency department with PE findings. Wells scoring and Wells scoring with AF were performed for each patient. Out of 250 patients, 165 patients were diagnosed as PE. Wells score was >4 in 61.8% of patients with PE and 28.2% of patients without PE. Out of false negative 63 patients with PE, 21 of them had AF. According to Wells scoring with AF the score of 148 (89.7%) patients with PE diagnosis was ≥3, whereas the score of 45 (52.9%) patients without PE was ≥3. AF was detected in 15.8% of patients with PE. The sensitivity of Wells score with AF was significantly higher than that of the Wells score (p<0.001). As a result, when AF, which is one of an important PE cause such as DVT and malignancy, was added to the Wells criteria, an additional correct PE estimate was obtained in 46 patients. We recommend using Wells score with AF since prediagnosing more PE is more valuable than having some false negative PE predictions.

BCG sepsis following inadvertent intravenous BCG administration for the treatment of bladder cancer can be effectively cured with anti-tuberculosis medications.

AIM: To the best of our knowledge we are presenting the very first case of inadvertent intravascular administration of BCG and its successful treatment with anti-tuberculosis medications on a patient with superficial bladder cancer. METHODS: A search of the English literature (PubMed/Medline) was performed concerning inadvertent BCG administration for bladder cancer by using the key words. RESULTS: The patient was admitted to our hospital with high fever and chills a few hours after intravascular BCG administration. Chest CT showed bilateral infiltration of the lungs. Patient was placed on anti-tuberculosis treatment including isoniazid, rifampycin, ethambutol and methylprednisolone initially; and this treatment was adjusted according to his clinical course and liver function tests. By the end of the 4th week of hospitalisation patient was responded well with normalisation of his clinical status, liver function tests and a normal chest X-ray. Thereafter, he was discharged home on isoniazid, ethambutol for 6 months, streptomycin, cycloserine-C and ofloxacin for 2 months, methylprednisolone which was stopped eventually after dose reduction. On follow-up at 6th month after discharge from the hospital, he was fully recovered with normal chest X-ray and blood tests. CONCLUSIONS: Development of severe sepsis is inevitable following inadvertent intravascular BCG administration. Therefore, urologists should warn and inform not only their patients and families but also healthcare workers such as nurses regarding the route of administration of the BCG treatment for bladder cancer. Our experience also proved that such a serious complication can be successfully treated if promptly acted.
