Background: LDBio immunochromatographic lateral flow assay, a point-of care test, detects IgM/IgG antibodies against Aspergillus fumigatus (LDBio-ALFA). LDBio-ALFA has been evaluated for diagnosing chronic pulmonary aspergillosis (CPA) in hospital patients, though its efficacy in field settings remains unexamined.

Objective: Our primary objective was to assess the diagnostic accuracy of LDBio-ALFA in diagnosing CPA in a field and a hospital cohort.

Background: The risk factors for interstitial lung disease (ILD) in rheumatoid arthritis (RA) are inconsistent among previous studies. Furthermore, the factors associated with the emergence of the recently defined progressive fibrosing (PF) phenotype are unknown. Herein, we analyze the risk factors for ILD in RA.

Article Synopsis
  • The study compares various screening methods for allergic bronchopulmonary aspergillosis (ABPA) in asthma patients to find the most effective approach.
  • Serum IgE testing emerged as the best option, being the most cost-effective while providing high diagnostic accuracy.
  • Other methods, like total IgE and imaging, were more expensive and either missed cases or required many additional tests.

Objective: Aspergillus sensitisation (AS) is seen in many patients with chronic pulmonary aspergillosis (CPA). However, the clinical relevance of AS in CPA remains unclear. In this study, we assess the clinical significance of AS in CPA.

Objectives: Allergic bronchopulmonary aspergillosis (ABPA) is a complex lung disease associated with significant morbidity. The ABPA Working Group (AWG) of the International Society for Human and Animal Mycology (ISHAM) revised their management guidelines in 2024, but there is currently no standardised tool to assess adherence to these recommendations.

Methods: We extracted key recommendations from the updated 2024 ISHAM-AWG guidelines, focusing on critical areas: screening and diagnosis of ABPA, managing acute and treatment-dependent ABPA, and monitoring treatment response.

Article Synopsis
  • Dermatomyositis is a complex disease where about 7-10% of patients have the Anti MDA-5 antibody, often leading to severe symptoms like skin ulcers and quickly worsening lung disease.
  • A case study highlights a 22-year-old male who experienced severe respiratory distress and ultimately died from complications related to both dermatomyositis and H1N1 influenza.
  • Postmortem tests revealed the presence of Anti MDA-5 and Ro-52 antibodies, suggesting they are significant biomarkers for diagnosing and assessing the prognosis of patients with related inflammatory conditions, particularly those involving lung issues.

Article Synopsis
  • The study examined the effects of sex on outcomes of allergic bronchopulmonary aspergillosis (ABPA) by analyzing data from 731 subjects over 13 years.
  • Researchers compared various factors including clinical features and exacerbation rates between men and women, focusing on whether women had higher exacerbation rates.
  • While women had a slightly higher exacerbation rate (44.5% vs. 38.2%), the difference wasn't statistically significant, prompting the need for further prospective studies to confirm these results.

Background: Several genetic variants are associated with the risk of idiopathic pulmonary fibrosis (IPF). These have not been systematically reviewed.

Methods: We searched the PubMed, Embase and GWAS Catalog databases for studies indexed between inception and 15 January 2024 describing genetic variants associated with IPF susceptibility.

Anticholinergic toxicity and neuroleptic malignant syndrome (NMS) are common toxidromes in medical emergencies. However, their co-occurrence, resulting in a dual toxidrome, is rare and presents significant diagnostic and therapeutic challenges. We present the case of a 23-year-old young male with polysubstance dependence, admitted following combined trihexyphenidyl and risperidone toxicity.

Article Synopsis
  • Allergic bronchopulmonary aspergillosis (ABPA) was analyzed in relation to asthma severity among 543 adult patients categorized as mild, moderate, or severe according to GINA guidelines.
  • The study found that ABPA prevalence was 11.1% in mild asthma, 21% in moderate asthma, and 20.7% in severe asthma, indicating that severity does not significantly influence ABPA occurrence (P = .12).
  • The research emphasizes the need for screening all asthma patients for ABPA, regardless of their asthma severity, and suggests further studies to confirm these results.

Unlabelled: Tuberculosis (TB) is an important cause of morbidity and mortality globally. About 3-4% of hospitalized TB patients require admission to the intensive care unit (ICU); the mortality in these patients is around 50-60%. There is limited literature on the evaluation and management of patients with TB who required ICU admission.

Background And Objective: There is a need for simple functional test to assess treatment response in chronic pulmonary aspergillosis (CPA) in resource-constrained settings. The one-minute-sit-to-stand test (1-min-STS) is one such test. However, the minimal important difference (MID) for 1-min-STS in subjects with CPA remains unknown.

Background: The role of 2-deoxy-2-18(F) fluoro-D-glucose (FDG) positron emission tomography (PET)-computed tomography (CT) in assessing treatment response in chronic pulmonary aspergillosis (CPA) remains to be determined.

Objective: To compare changes in FDG-PET/CT parameters in CPA subjects with treatment success or failure.

Methods: We treated consecutive treatment-naïve CPA subjects with six months of oral itraconazole.

Background: Three techniques have been described for aspirating the bronchoalveolar lavage (BAL) fluid, namely the wall mount suction (WMS), manual suction (MS), and manual suction with tubing (MST). However, there is no direct comparison among the 3 methods.

Methods: We randomized patients undergoing flexible bronchoscopy and BAL in a 1:1:1 ratio to one of the 3 arms.

<b><br>Introduction:</b> Necrotizing fasciitis (NF) is an expeditiously escalating inflammatory infection of the fascia, with secondary necrosis of the subcutaneous tissues. To aid diagnosis, the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) scoring system was devised to stratify the likelihood of infection in patients on presentation.</br> <b><br>Aim:</b> The study aimed to investigate and quantify the relationships between the LRINEC scoring system and the outcomes such as the need for amputation, length of hospital stay, and mortality in patients with necrotizing fasciitis.

Background: Post-tuberculosis lung abnormality (PTLA) is the most common risk factor for chronic pulmonary aspergillosis (CPA), and 14%-25% of the subjects with PTLA develop CPA. The pathogenesis and the host immune response in subjects with PTLA who develop CPA need to be better understood.

Methods: We prospectively compared the innate and adaptive immune responses mounted by patients of PTLA with or without CPA (controls).

  • A study analyzed mixed mould infections in patients with COVID-19-associated pulmonary mucormycosis (CAPM) to determine the prevalence of co-existing COVID-19-associated pulmonary aspergillosis (CAPA) and its impact on early mortality.
  • Among 105 patients with CAPM, 20% had mixed mould infections, and those with CAPA experienced significantly higher early mortality rates (42.9%) compared to those without (17.9%).
  • The findings suggest that co-existing CAPA worsens the prognosis for CAPM patients, highlighting the need for further research on mixed mould infections globally.
