Administration of a Nutraceutical Mixture Composed by Aloe arborescens, Annona muricata, Morinda citrifolia, Beta rubra, Scutellaria baicalensis, and Vaccinium myrtillus Reduces Doxorubicin-Induced Side Effects.

The antibiotic doxorubicin is often used as an anti-neoplastic drug; however, many patients showed very unpleasant side-effects. Previous studies have demonstrated that dietary substances such as Aloe arborescens, Annona muricata, Morinda citrifolia, Beta rubra, Scutellaria baicalensis, and Vaccinium myrtillus may have anti-oxidant, anti-proliferative, and anti-inflammatory effects. The purpose of this study was to investigate the protective effects of a mixture of these components in an experimental model of doxorubicin toxicity. Rats (n = 30) received doxorubicin (5 mg/kg/day) for 4 weeks and were randomized to receive the dietary mixture 2 hours following the first doxorubicin injection and until the end of the experiment. Animals were killed following 4 weeks, and blood, liver, and heart were collected for further analysis. The dietary supplement improved the depressed body weight and food consumption induced by DOX. In addition, the nutraceutical mixture reduced oxidative stress, ameliorated the morphological score, and preserved liver and heart structure, demonstrating a protective effect. These data show for the first time that the mixture of Aloe arborescens, Annona muricata, Morinda citrifolia, Beta rubra, Scutellaria baicalensis, and Vaccinium myrtillus may be useful to reduce the side effects following treatment with doxorubicin, and might ameliorate the quality of life of patients following chemotherapy.

Stable consumption of swordfish favors, whereas stable consumption of oily fish protects from, development of postpartum thyroiditis.

PURPOSE: In 236 pregnant women, we showed that selective or predominant consumption of swordfish (group A) was associated with high rates of positivity for serum thyroid autoantibodies (TPOAb and TgAb) throughout day 4 postpartum. In contrast, selective or predominant consumption of oily fish (group B) was associated with TPOAb and TgAb negativity. Rates were intermediate in group C (scanty consumption of swordfish) and group D (consumption of fish other than swordfish and oily fish). Gestational TPOAb positivity is a risk factor for postpartum thyroiditis (PPT), which evolves into permanent hypothyroidism (PH) in about 50% of cases. Purpose of this study was to verify that the different rates of thyroid autoantibodies in the four groups translated into different PPT rates. METHODS: We expanded our previous cohort (n = 412) and duration of follow-up (month 12 postpartum), and measured frequency of PPT and PH. RESULTS: At first timester of gestation, we confirmed the different Ab positivity rates in group A vs. group B (TPOAb = 21.7% vs. 4.7%, P < 0.0001; TgAb = 14.1% vs. 2.4%, P < 0.05). Overall, PPT prevalence was 63/412 (15.3%), but 22/92 in group A (23.9%), 4/85 in group B (4.7%; P < 0.0001 vs. group A), 17/108 (15.7%) in group C, and 16/117 (13.7%) in group D. Approximately half of the PPT women had PH, regardless of fish group. CONCLUSIONS: In conclusion, stable consumption of oily fish (which is enriched in polyunsaturated omega-3 fatty acids) protects from PPT, while stable consumption of swordfish (which is enriched in pollutants) favors PPT. Thus, a dietary prophylaxis of PPT is possible.

Type of fish consumed and thyroid autoimmunity in pregnancy and postpartum.

Fish consumption or supplementation with omega-3 fatty acids was reported to cure and/or prevent autoimmune and nonautoimmune disorders. Serum positivity for thyroid autoantibodies is a predictive marker of postpartum thyroiditis and postpartum depression. We hypothesized that stable consumption of the omega-3-rich oily fish was associated with a more favorable profile of serum thyroid antibodies throughout pregnancy and early postpartum compared with stable consumption of swordfish, a predator that concentrates pollutants. We prospectively measured serum thyroglobulin antibodies and thyroperoxidase antibodies in pregnancy (first, second trimesters) and postpartum (day 4), in 236 thyroid disease-free, nonsmoker Caucasian women with stable dietary habits. We did not measure thyroid autoantibodies prior to pregnancy. Women were divided into groups A (n = 48; swordfish), B (n = 52; oily fish), C (n = 68; swordfish + other fish, not necessarily oily fish), and D (n = 68; fish other than swordfish and oily fish). Major endpoints were positivity rates and serum concentrations of the two autoantibodies. We resorted to previous studies for the estimated content of fatty acids and microelements in the consumed fish. Positivity rates and serum concentrations of both antibodies were the greatest in group A and the lowest in group B (P < 0.001 and P < 0.05 to < 0.001, respectively). Relationship between monthly fish consumption and serum concentrations of either antibody was direct in group A but inverse in group B. The estimated content of omega-3 fatty acids in fish consumed by group B was the greatest (P < 0.001 vs. any other group). These data reinforce recommendations that pregnant women should avoid consuming swordfish and indicate consumption of oily fish as a favorable alternative. Because thyroid autoantibodies are markers of autoimmune-related postpartum problems, our data suggest a dietary prophylaxis of such problems.
