In this study different systemic manifestations in chronic arsenic poisoning were evaluated.</p> <p><strong>Methods: </strong>A nonrandomized, controlled, cross‑sectional, observational study was carried out in Arsenic Clinic, Institute of Postgraduate Medical Education and Research, Kolkata, West Bengal, over a period of 1 year 4 months. Seventy‑three cases diagnosed clinically, consuming water containing arsenic &ge;50 mg/L and having hair and nail arsenic level &gt;0.6 mg/L, were included. Special investigations included routine parameters and organ‑specific tests. Arsenic levels in the drinking water, hair, and nail were measured in all. Twenty‑five nonsmoker healthy controls were evaluated.</p> <p><strong>Results: </strong>Murshidabad and districts adjacent to Kolkata, West Bengal, were mostly affected. Middle‑aged males were the common sufferers. Skin involvement was the commonest manifestation (100%), followed by hepatomegaly [23 (31.5%)] with or without transaminitis [7 (9.58%)]/ portal hypertension [9 (12.33%)]. Restrictive abnormality in spirometry [11 (15.06%)], bronchiectasis [4 (5.47%)], interstitial fibrosis [2 (2.73%)], bronchogenic carcinoma [2 (2.73%)], oromucosal plaque [7 (9.58%)], nail hypertrophy [10 (13.69%)], alopecia [8 (10.95%)], neuropathy [5 (6.84%)], and Electrocardiography abnormalities [5 (6.84%)] were also observed.</p><p><strong>Conclusions: </strong>Mucocutaneous and nail lesions, hepatomegaly, and restrictive change in spirometry were the common and significant findings. Other manifestations were characteristic but insignificant.</p><p><strong>Key words: </strong>Arsenic poisoning, ground water, India, West Bengal</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/586http://ijpm.mui.ac.ir/index.php/ijpm/article/download/586/1105
