Updates in idiopathic pulmonary hemosiderosis in 2022: A state of the art review.

This manuscript reports the recent advances in idiopathic pulmonary hemosiderosis (IPH), a rare cause of diffuse alveolar hemorrhage in children and adults. This narrative review of the literature summarizes different aspects of IPH, including proposed pathogenesis, patient demographics, clinical and radiological characteristics, treatment, and prognosis. Additionally, the association between Celiac Disease (CD) and IPH is carefully evaluated. IPH is a frequently misdiagnosed disease. The delay in the diagnosis of IPH is often significant but fortunately, appears to have decreased in recent years. IPH in adults and children have distinct demographic preferences. The autoantibodies are common in IPH but with a definite difference between the adult and pediatric populations. The definitive diagnosis of IPH requires lung biopsy and careful exclusion of all competing diagnoses, even with lung biopsy showing bland pulmonary hemorrhage. The presence of nonspecific inflammatory cells or lymphoid aggregates may suggest a secondary immunologic phenomenon and needs careful evaluation and follow-up. A substantial number of patients suffer from coexisting CD, also known as Lane-Hamilton syndrome (LHS), and all patients with IPH need to be evaluated for LHS by serology. Although strict gluten free diet can manage the majority of patients with LHS, other patients generally require immunosuppressive therapy. The corticosteroids are the backbone of IPH therapy. Recently utilized experimental treatment options include mesenchymal stem cell transplant, liposteroid and bronchial artery embolization. The immunosuppression should be adjusted to achieve optimal disease control. Patients may progress to end-stage lung disease despite all measures, and lung transplantation may be the only viable option.

Efficacy and safety of Shufeng Jiedu capsule in the treatment of COVID-19: A protocol for systematic review and meta analysis.

BACKGROUND: Coronavirus disease 2019 (COVID-19) epidemic is spreading worldwide. Shufeng Jiedu capsule (SFJDC) is a commonly used drug in the treatment of COVID-19. However, there is insufficient evidence for clinical efficacy and safety. METHODS: Two authors will independently search the Chinese National Knowledge Infrastructure (CNKI), VIP database, Wanfang database, the Cochrane Library, EMBASE, PubMed and Web of Science, in English and Chinese. All analysis will be performed based on the Cochrane Handbook for Systematic Reviews of Interventions. Review Manager 5.3 and Stata 16.0 software will be used to analyze the eligible data. RESULTS: This protocol will conduct a systematic review and meta-analysis of literature listed above, and reliable outcomes about the clinical efficacy and safety of SFJDC in the treatment of COVID-19 will be obtained. CONCLUSIONS: These findings will provide guidance for clinicians and patients using SFJDC for COVID-19 treatment. PROSPERO REGISTRATION NUMBER: CRD42020185764.
