Phenotype match inherited by genes is in most cases present in monozygotic twins. Their phenotypic resemblance is unfortunately characterized by strong susceptibility for the development of chronic non-infectious diseases. One of the most common non-infectious chronic diseases that are phenotipically represented in twins is diabetes mellitus. Genetic imbalance is, in most cases, placed in 2, 3, 7, 8, 11, 12, 19 and 20 chromosomal pair of the human genome. This study describes a pair of monozygotic twins, aged 54, who were diagnosed for diabetes type 2 ten years earlier. The first patient had trophic changes of muscles and skin tissues of the lower limb, and a necrotic wound on his right leg tibial region with the claudication distance of 50 m. After arteriography, he was referred by a vascular surgeon for hyperbaric oxygen therapy (HBO). HBO protocol implied 70 min. application of 100% oxygen at 2.5 absolute atmospheres. After the first series of HBO therapies consisting of 20 HBO treatments, claudication was eliminated and the necrotic wound healed. Next, surgical aortofemoral bypass was done. During the second HBO treatment, his monozygotic twin brother presented with angiopathic changes due to diabetes. In both patients, biochemical parameters corresponded to the expected level for diabetes type 2 imbalance, and the localization of the chromosomal defect (placed on 3, 11 and 19 chromosomal pair) was also in accordance with the respective disorder. After they were included into next 10 HBO treatments, Doppler imaging of the major arteries of limbs revealed normal findings. Identical genetic impairment in monozygotic twins can lead to identical somatic changes with resultant consequences. HBO treatment of such patients associated with other therapeutic procedures (conducted by diabetologist, vascular surgeon and physiatrist) can postpone or prevent irreversible changes occurring due to blood vessel disorders.
