Se presentan los resultados de un estudio abierto de seguimiento, realizado para analizar la eficacia de la combinación de apoyo psicológico con chicles de 2 y 4mg de nicotina, en el tratamiento del tabaquismo.

Se han estudiado dos grupos de fumadores. Un grupo A, formado por 124 sujetos (74 varones y 50 mujeres) con una edad media de 37,4 (15,3) años, fumadores de 15,3 (8,7) cigarrillos diarios y un bajo grado de dependencia física a nicotina, 1,7 (1,3) puntos en el test de Fagerström. Un grupo B, formado por 107 sujetos (61 varones, 46 mujeres) con edad media de 38,9 (14,6) años, fumadores de 26,9 (9,3) cigarrillos diarios y con moderado-alto grado de dependencia física a la nicotina, 6,1 (2,4) puntos en el test de Fagerström. Las cifras entre paréntesis corresponden a la desviación estándar. Ambos grupos fueron tratados con apoyo psicológico leve y chicles de 2mg de nicotina (grupo A) y de 4mg (grupo B) durante un período de 12 semanas a dosis de una pieza de chicle cada 90-120 min al día durante el período de vigilia, reduciendo progresivamente la misma a partir de la sexta a la octava semanas. Los sujetos fueron vistos en ocho ocasiones a lo largo de un año (primer día de consulta y a la primera, segunda, cuarta, octava y duodécima semanas después del día de abandono, y el sexto y duodécimo mes).

A las 12 semanas de seguimiento, 61 sujetos (49%) del grupo A permanecieron abstinentes y 50 (47%) del grupo B. Estas cifras se redujeron a 56 (45%) y 46 (43%), respectivamente, al año de seguimiento. Entre los pacientes que alcanzaron con éxito los 3 meses de seguimiento, habían utilizado correctamente el chicle el 81% en el grupo A, y el 87% en el grupo B.

Molestias orofaríngeas, dentarias y de la articulación temporomandibular, hipo, meteorismo y pirosis fueron los efectos adversos más comunes (3-18%). Éstos siempre fueron leves y no se detectaron más allá de la octava semana de tratamiento.

En conclusión, la utilización de terapia combinada (apoyo psicológico leve más chicle de 2 o 4mg de nicotina) de acuerdo con el grado de dependencia física de los fumadores ofrece entre un 43-45% de éxitos en la abstinencia al año de seguimiento. Los efectos secundarios fueron escasos y leves.

We present the results of an open follow-up study aimed at analyzing the efficacy of combining psychological counseling with prescription of 2 and 4mg nicotine gum to treat smokers.

Two groups of smokers wer studied. Group A contained 124 subjects (74 men, 50 women) with a mean age of 37.4 (15.3) yr who were smokers of 15.3 (8.7) cigarettes/day. In this group physical addiction to nicotine was low, assessed as 1.7 (1.3) on the Fagerström test. Group B consisted of 107 subjects (61 men, 46 women) with a mean age of 38.9 (14.6) who were smokers of 26.9 (9.3) cigarettes/day and whose level of physical addiction to nicotine was moderate- to-high, assessed as 6.1 (2.4) on the Fagerström test. Standard deviations are shown between parentheses. Both groups were given minimal psychological counseling; additionally, patients were prescribed one piece of nicotine gum very 90 to 120 minutes during waking hours (2mg in group A and 4mg in group B). The dose was gradually reduced after the sixth to the eighth week. The subjects were seen eight times over the first year (first day of consultation and during the first, second, fourth, eight and twelfth weeks after quitting, and again after six and twelve months).

After twelve weeks of follow-up, sixty-one subjects (49%) in group A and 50 (47%) in group B were still abstinent. These proportions fell to 56 (45%) and 46 (43%), respectively, after one year of follow-up. Eighty-one percent of group A patients who were successful after three months of follow-up, and 87% of the successful group B patients, had used the nicotine gum as prescribed.

Oropharyngeal, dental, and temporo-mandibular joint symptons, hiccoughins, flatulence and heartburn were the most frequent side effects (ranging from 3% to 18%). Side effects were always slight and were not detected after the eighth week of treatment.

In conclusion, combined therapy (minimal psychological counseling plus use of 2 or 4mg nicotine gum depending on the level of physical addiction) yields a success rate between 43% and 45% still abstaining after one year of follow-up. Side effects are few and mild.
