Medical interventions for chronic rhinosinusitis in cystic fibrosis

BACKGROUND

Chronic rhinosinusitis frequently occurs in people with cystic fibrosis. Several medical interventions are available for treating chronic rhinosinusitis in people with cystic fibrosis; for example, different concentrations of nasal saline irrigations, topical or oral corticosteroids, antibiotics - including nebulized antibiotics - dornase alfa and modulators of the cystic fibrosis transmembrane conductance regulator (CFTR) (such as lumacaftor, ivacaftor or tezacaftor). However, the efficacy of these interventions is unclear. This is an update of a previously published review.

OBJECTIVES

The objective of this review is to compare the effects of different medical interventions in people diagnosed with cystic fibrosis and chronic rhinosinusitis.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and hand searching of journals and conference abstract books. Date of last search of trials register: 09 September 2021. We also searched ongoing trials databases, other medical databases and the reference lists of relevant articles and reviews. Date of latest additional searches: 22 November 2021.

SELECTION CRITERIA

Randomized and quasi-randomized trials of different medical interventions compared to each other or to no intervention or to placebo.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials identified for potential inclusion in the review. We planned to conduct data collection and analysis in accordance with Cochrane methods and to independently rate the quality of the evidence for each outcome using the GRADE guidelines.

MAIN RESULTS

We identified no trials that met the pre-defined inclusion criteria. The most recent searches identified 44 new references, none of which were eligible for inclusion in the current version of this review; 12 studies are listed as excluded and one as ongoing.

AUTHORS' CONCLUSIONS

We identified no eligible trials assessing the medical interventions in people with cystic fibrosis and chronic rhinosinusitis. High-quality trials are needed which should assess the efficacy of different treatment options detailed above for managing chronic rhinosinusitis, preventing pulmonary exacerbations and improving quality of life in people with cystic fibrosis.

Intracranial Complications due to Chronic Suppurative Otitis Media-Atticoantral Disease with a Reference to its Microbiological Profile: A Retrospective Study

Introduction: Intracranial Complications (ICC) in patients with Chronic Suppurative Otitis Media-Atticoantral Disease (CSOMAAD) is a life threatening disease. Knowing the microbiological profile of the causative organisms will help in selecting empiric antibiotic. Aim: To determine the demographic pattern and clinical presentation of patients with CSOM-AAD presenting with ICC, and to assess the microbiological profile of causative organisms. Materials and Methods: This was a retrospective study, where medical records of all patients diagnosed with CSOM-AAD and ICC, in a tertiary teaching hospital, Manipal, Karnataka, India, between July 2012 and June 2018 were reviewed. The data regarding demographics, clinical and audiological evaluation, microbiological reports were analysed. Data was entered into Microsoft Excel sheet 2010 and was calculated as mean, median and percentages. Results: Out of total 244 patients with CSOM-AAD, 15 presented with ICC. The age range was between 17 to 41 years (median age-21years). The most common complaint was headache, n=11 (73%) and the most common complication was intracranial abscess, n=10 (67%). In three cases, sampling from different sites isolated different organisms and hence a total of 20 samples (11 from ear swab, six from abscess drained pus, two from cerebrospinal fluid and one from blood culture) were analysed. Gram Negative Bacilli (GNB) were isolated most of the times, n=10 (50%) followed by Gram Positive Cocci (GPC), n=6 (30%) and anaerobes, n=2 (10%). Most of the isolated GNB and GPC were susceptible to carbapenem and vancomycin, respectively. Conclusion: Intracranial complications are usually seen in young adults, and they present with headache, fever and ear discharge. Majority of the complications are caused by GNB. Vancomycin and carbapenem provide empiric cover for GPC and GNB, respectively

Lumbar sympathectomy techniques for critical lower limb ischaemia due to non-reconstructable peripheral arterial disease

BACKGROUND

Critical lower limb ischaemia (CLI) is a manifestation of peripheral arterial disease (PAD) that is seen in patients with typical chronic ischaemic rest pain or patients with ischaemic skin lesions - ulcers or gangrene - for longer than 2 weeks. Critical lower limb ischaemia is the most severe form of PAD, and interventions to improve arterial perfusion become necessary. Although surgical bypass has been the gold standard for revascularisation, the extent or the site of disease may be such that the artery cannot be reconstructed or bypassed. These patients require other modalities of treatment, for example, vasodilatation by drugs or lumbar sympathectomy to relieve pain at rest and to avoid amputations. A systematic review of randomised controlled trials is required to evaluate the effects of lumbar sympathectomy in treating patients with CLI due to non-reconstructable PAD.

OBJECTIVES

The objective of this review is to assess the effects of lumbar sympathectomy by open, laparoscopic and percutaneous methods compared with no treatment or compared with any other method of lumbar sympathectomy in patients with CLI due to non-reconstructable PAD.

SEARCH METHODS

The Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (January 2016) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12). In addition, the CIS searched clinical trials databases for details of ongoing and unpublished studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing any of the treatment modalities of lumbar sympathectomy, such as open, laparoscopic and chemical percutaneous methods, with no treatment or with any other method of lumbar sympathectomy for CLI due to non-reconstructable PAD were eligible. To decrease the bias of including participants that may be incorrectly diagnosed with CLI, review authors defined CLI as persistently recurring ischaemic rest pain requiring regular analgesia for more than two weeks, or ulceration or gangrene of the foot or toes, attributable to objectively proven arterial occlusive disease by measurement of ankle pressure of < 50 mmHg or toe pressure < 30 mmHg. We defined non-reconstructable PAD as a resting ankle brachial index (ABI) < 0.9 when no reasonable open surgical or endovascular revascularisation treatment option is available, as determined by individual trial vascular specialists.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies identified for potential inclusion in the review. We planned to conduct data collection and analysis in accordance with the Cochrane Handbook for Systematic Review of Interventions.

MAIN RESULTS

We identified no studies that met the predefined inclusion criteria. To decrease the bias of including participants who may be incorrectly diagnosed with CLI, we based our inclusion criteria on objective tests, as described above. The randomised trials identified by the literature search were performed before such objective criteria for selection were applied and therefore were not eligible for inclusion in the review.

AUTHORS' CONCLUSIONS

We identified no RCTs assessing effects of lumbar sympathectomy by open, laparoscopic and percutaneous methods compared with no treatment or compared with any other method of lumbar sympathectomy in patients with CLI due to non-reconstructable PAD. High-quality studies are needed.
