Detection of Acute Lymphoblastic Leukemia Involvement in Pleural Fluid in an Adult Patient with Ataxia Telangiectasia by Flow Cytometry Method

Background Ataxia-telangiectasia is an autosomal recessive, multi-system, and life-shortening disease caused by mutations in the ataxia-telangiectasia mutated gene. Although widely reported, there are no studies that give a comprehensive picture of this intriguing condition. Objectives Understand the natural history of ataxia-telangiectasia (A-T), as reported in scientific literature. Search methods 107 search terms were identified and divided into 17 searches. Each search was performed in PubMed, Ovid SP (MEDLINE) 1946-present, OVID EMBASE 1980 –present, Web of Science core collection, Elsevier Scopus, and Cochrane Library. Selection criteria All human studies that report any aspect of A-T. Data collection and analysis Search results were de-duplicated, data extracted (including author, publication year, country of origin, study design, population, participant characteristics, and clinical features). Quality of case-control and cohort studies was assessed by the Newcastle-Ottawa tool. Findings are reported descriptively and where possible data collated to report median (interquartile range, range) of outcomes of interest. Main results 1314 cases reported 2134 presenting symptoms. The most common presenting symptom was abnormal gait (1160 cases; 188 studies) followed by recurrent infections in classical ataxia-telangiectasia and movement disorders in variant ataxia-telangiectasia. 687 cases reported 752 causes of death among which malignancy was the most frequently reported cause. Median (IQR, range) age of death (n = 294) was 14 years 0 months (10 years 0 months to 23 years 3 months, 1 year 3 months to 76 years 0 months). Conclusions This review demonstrates the multi-system involvement in A-T, confirms that neurological symptoms are the most frequent presenting features in classical A-T but variants have diverse manifestations. We found that most individuals with A-T have life limited to teenage or early adulthood. Predominance of case reports, and case series demonstrate the lack of robust evidence to determine the natural history of A-T. We recommend population-based studies to fill this evidence gap.

Ataxia-telangiectasia (A-T) is an ultrarare autosomal recessive disorder and occurs in all racial and ethnic backgrounds. Clinically, children and young people with A-T are affected by sinopulmonary infections, neurological deterioration with concomitant bulbar dysfunction, increased sensitivity to ionizing radiation, immunodeficiency, a decline in lung function, chronic liver disease, endocrine abnormalities, cutaneous and deep-organ granulomatosis, and early death. Pulmonary complications become more frequent in the second decade of life and are a leading cause of death in individuals with A-T. Oropharyngeal dysphagia is common, progressive, and a risk factor for frequent respiratory infections. Immunodeficiency is non-progressive in most patients with A-T. If severe infections occur, one should be aware of other possible causes, such as aspiration. We provide an overview of current best practice recommendations, which are based on combinations of extrapolation from other diseases and expert opinion. These include proactive surveillance, monitoring, and early management to improve lung health in this devastating multisystem disease.

Detection of Acute Lymphoblastic Leukemia Involvement in Pleural Fluid in an Adult Patient with Ataxia Telangiectasia by Flow Cytometry Method
