The high recurrence risk in pedigrees with early and severe PKD strongly suggests common familial. Adding DDAVP and caffeine simultaneously increased the Isc to levels greater than when either agent was added alone.

Horizontal dashed line indicates basal cAMP level . V. Caffeine was used for many years reagent to block PDE biochemical studies until more potent methyl isobutyl xanthine theophylline and specific rolipram inhibitors became available.

However no direct studies of renal cells derived from human ADPKD cysts have examined the hypothesis that caffeine concentrations are clinically relevant has potential to adversely affect enlargement by promoting increased intracellular levels cAMP. Primary cilia play an important role in cyst formation
