Adult-onset asthma induced by COVID-19: A case report.

COVID-19 commonly presents respiratory symptoms that can linger after the acute phase. Asthma onset or exacerbations have been documented after viral infections although rarely in adults. We report a case of adult-onset asthma triggered by mildly symptomatic COVID-19 in a 24-year-old female without previous respiratory issues. Fatigue, exercise dyspnea, and intermittent cough persisting a month after the infection, led to spirometry testing, revealing reduced lung function, with normal CT imaging. Budesonide/formoterol therapy improved symptom control and repeated spirometry testing showed improving but reduced lung function after five months. Methacholine testing was thus conducted and confirmed bronchial hyperreactivity and adult-onset asthma. Clinicians should be attentive to persistent respiratory symptoms and suggest appropriate testing. Further research should focus on underlying mechanisms of this phenomenon.

Burden and mortality of sepsis and septic shock at a high-volume, single-center in Vietnam: a retrospective study.

BACKGROUND: Sepsis and septic shock have high mortality rates and often require a prolonged hospital stay. Patient outcomes may vary according to multiple factors. We aim to determine the prevalence of antimicrobial resistance and factors associated with mortality and hospital stay. METHODS: Clinical and microbiological data of patients with sepsis or septic shock were retrospectively collected for 15 months. Patients with negative blood cultures and patients that did not meet the SEPSIS 3 criteria were excluded. RESULTS: We included 48 septic shock and 28 septic patients (mean APACHE II 20.32 ± 5.61 and mean SOFA 9.41 ± 3.17), with a mean age of 60.5 ± 16.8 years and 56.6% males. WBCs, neutrophils, INR, and fibrinogen levels were significantly associated with mortality. 59.5% of the cultured bacteria were gram-negative (most common E. coli) and 27.8% were gram-positive (most common S. aureus), while 7.6% were other types of bacteria and 5.1% were fungi. Resistance patterns to gram-negative were varying, and resistance to piperacillin/tazobactam, carbapenems, and aminoglycosides were from 60% to 100% (A. baumanii), while they were highly sensitive to Colistin. E. coli was also resistant to ceftriaxone (77.8%) and sulbactam/cefoperazone (44.4%). Resistance rates for Gram-positives were high, from 86% to 100% for oxacillin, while for vancomycin, teicoplanin, and linezolid, they were often low but arrived up to 42.8%. According to our logistic regression analysis, patients over 65 year-old and those who received corticosteroids had a significantly increased risk of in-hospital mortality (OR: 4.0; OR: 4.8). CONCLUSION: Sepsis still poses a significant threat to patients' health, even when positive blood culture results allow the administration of specific antibiotic treatment.

Hyponatremia in tuberculous meningitis: A systematic review and meta-analysis.

BACKGROUND: Tuberculous meningitis (TBM), manifests as the most severe involvement of the nervous system by Mycobacterium tuberculosis, it has a high mortality rate and a spectrum of systemic and neurological complications that can lead to debilitating or fatal sequelae, whereas hyponatremia is the commonly encountered life-threatening electrolyte disturbance. Thus, our study aimed to determine the prevalence, risk factors and differences in outcomes of hyponatremia in TBM. METHODS: This systematic review was registered in PROSPERO (CRD42018088089). A comprehensive electronic search was conducted through ten databases to find relevant articles. RESULTS: A total of 42 studies were included, 24 case reports and 18 retrospective studies. The prevalence rate of hyponatremia among TBM patients was 52% and the rate of death among those patients was 29%. The meta-regression analysis revealed that there was no significant effect of sodium level on the death rate in TBM patients (P-value = 0.9). Additionally, there was no significant difference in sodium level based on sex, and etiologies of hyponatremia. CONCLUSIONS: Hyponatremia is commonly present in patient with TBM, but it is not significantly correlated to the rate of death. However, it is necessary to treat this potentially life-threatening condition appropriately according to its etiology, further research is needed on its pathophysiology in TBM, its risk factors, and the most appropriate treatment.
