Forskolin versus sodium cromoglycate for prevention of asthma attacks: a single-blinded clinical trial.

To determine the efficacy of forskolin in preventing asthma attacks, we performed a single-blinded clinical study in children and adult out-patients at a public hospital in Mexico. Forty patients of either sex with mild persistent or moderate persistent asthma were assigned randomly to 6 months of treatment with forskolin at 10 mg/day orally (capsules) or with two inhalations of sodium cromoglycate every 8 h, i.e. three times a day. The number of patients who had asthma attacks during the treatment period was significantly lower among those receiving forskolin (8/20, 40%) than among those receiving sodium cromoglycate (17/20, 85%). Values of forced expiratory volume in 1 s and forced expiratory flow, mid-phase, A similar in the two groups during the treatment period. We conclude that forskolin is more effective than sod cromoglycate in preventing asthma attacks in patients with mild persistent or moderate persistent asthma.

[Respiratory changes in obesity. Functional and clinical aspects. Study of 26 cases].

A study was made, at the altitude of Mexico City, of the clinic aspects and of the pulmonary function of 26 obese subjects more than 45% overweight. This excess weight habitually produces severe disturbances in pulmonary and/or heart function. In 50% of the patients, clinic, radiologic and electrocardiographic manifestations were found which suggested the existence of pulmonary arterial hypertension. This provoked right heart failure in 19% of the cases. The most constant alterations in the pulmonary volumes was the decrease in the VER, which occurred in 96% of the cases. Most of the patients had hypoxemia (92.5), which was produced mainly by the increase in venoarterial shunts. Although the clinic manifestations were similar to those described in Pickwick's syndrome, alveolar hypoventilation was presented in only a minority of the cases. No relationship was found between the degree of obesity and alveolar hypoventilation. Altitudes of 2,200 meters or more apparently favor hypoxemia in obese patients, and "protects" them from the hypercapnea. The altitude of Mexico City may be one of the reasons why alveolar hypoventilation is observed in only 15% of the cases.
