To the Editor:

Various aspects of acquired renal cystic disease [1] of the native kidneys of the patients with chronic renal failure [2] as well as of those on maintenance hemodialysis [2],[3] , along with selected abstracts on the same subjects [4] were provided to the readers in the recent issues of the journal. Here we would like to mention some other aspects of acquired renal cysts.

Renal cysts may also be acquired after infection or exposure to toxin [5] . The toxins associated with cystic diseases are concentrated in the intratubular fluid or renal epithelium [6] . "The location of such cyst varies with specific toxin. A partial list of chemicals causing renal cysts includes stilbesterol, corticosteroids, biphenyl, diphenylamine, alloxan, bacitracin, lithium chloride, lead acetate, sedormid, trichylor­phenoxyacetic acid, and streptozotocin" [5] . Having known the role of some of the chemicals and therapeutic agents for the development of renal cysts, we have, also, to consider the effect of various other chemicals in the environment, and therapeutic substances for the development as well as progression of renal cysts in both healthy subjects and those with renal disease. Much work is awaited in this area to resolve the mysteries behind them.

Chapman et al (cited by Orth et al) [7] observed that an association between severe renal cystic involvement in autosomal dominant polycystic kidney disease patients and greater pack year smoking history. In an excellent review on renal risks of smoking [7] , no mention was made on the association between tobacco smoke and the development of acquired renal cyst and/or malignant transformation of those cysts in others. In fact, earlier studies revealed renal elimination of nicotine and its metabolites , susceptibility of renal tissues to N­nitrosamines (a carcinogen) [9] , covalent DNA damage of the cells of the kidney excreting those chemicals [10] , higher serum levels of nicotine in hemodialysis patients who smoke than healthy smokers [11] , and increased risk of developing renal cell carcinoma in smokers. Hence, let us ask ourselves, "will any of the products of tobacco smoke and/or its' metabolites left out or accumulated in the body of those on dialysis or not, contribute to the develop­ment of acquired renal cysts and/or trigger malignant transformation of the cyst in some of the susceptible individuals?". If the answer is yes, then intense efforts should be made to inform and educate the population.
