Clinical and laboratory indices, including ammonia levels prior to\/during\/after the hospitalisation, were recorded, along with the duration of the hospitalisation, precipitants, ammonia\u2010lowering and psychoactive treatment, where applicable.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Over the studied time frame, 58 (56%) patients had single OHE hospitalisations, while 20 (19%) had 2\u20137 OHE hospitalisations. Of the 104 hospitalisations, 30\/63\/7% were for OHE grades II\/III\/IV, respectively. Of the 58 single hospitalisations, 40\/57\/3% were for OHE grades II\/III\/IV, respectively. Ammonia levels increased significantly with increasing OHE grade; those prior to admission\/after discharge were significantly lower than those on admission. Hospitalisations for grade IV OHE were longer. Ammonia levels on admission were lower in patients who were not fully recovered from OHE on discharge and those on chronic treatment with psychoactive drugs. All the above held true when analyses were restricted to the 58 single hospitalisations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Ammonia levels correlated with OHE presence and severity, and with the duration of hospitalization.
