    Breastfeeding does not protect against urinary tract infection in the first 3 months of life, but vitamin D supplementation increases the risk by 76%. Katikaneni R, Ponnapakkam T, Ponnapakkam A, Gensure R. Clin Pediatr (Phila). 2009 Sep;48(7):750-5. Epub 2009 Mar 4. PMID: 19264720 DOI: 10.1177/0009922809332588 The relative risk of UTI with breastfeeding versus formula feeding was 1.03 (0.58-1.82), and any breastfeeding versus no breastfeeding was 0.92 (0.58-1.45). Vitamin D supplementation increased the UTI risk, with a relative risk of 1.76 (1.07-2.91, P < .05). However, only formula-fed infants showed an increased risk of UTI after vitamin D supplementation.

    Conclusion: Vitamin D3 at doses equivalent to 2000 IU/d for 1 yr is safe in adolescents and results in desirable vitamin D levels.

    High prevalence of vitamin D deficiency despite supplementation in premenopausal women with breast cancer undergoing adjuvant chemotherapy. Crew KD, Shane E, Cremers S, McMahon DJ, Irani D, Hershman DL. J Clin Oncol. 2009 May 1;27(13):2151-6. Epub 2009 Apr 6. PMID: 19349547 DOI: 10.1200/JCO.2008.19.6162 Conclusion Vitamin D deficiency is highly prevalent in women with breast cancer. The current recommended dietary allowance of vitamin D is too low to increase serum 25-OHD greater than 30 ng/mL. Optimal dosing for bone health and, possibly, improved survival has yet to be determined.

    Clinical Responses to a Mega-dose of Vitamin D3 in Infants and Toddlers With Vitamin D Deficiency Rickets. Soliman AT, El-Dabbagh M, Adel A, Ali MA, Aziz Bedair EM, Elalaily RK. J Trop Pediatr. 2009 Jun 8. [Epub ahead of print] PMID: 19506025 doi:10.1093/tropej/fmp040 Conclusion: An IM injection of a mega dose of cholecalciferol is a safe and effective therapy for treatment of VDD rickets in infants and toddlers with normalization of all the biochemical parameters and healing of radiological manifestations. Measurement of serum 25(OH)D level is highly recommended in all short children with a clear need for a general vitamin D supplementation for all infants and young children in Qatar.

    High-dose oral vitamin D3 supplementation in the elderly. Bacon CJ, Gamble GD, Horne AM, Scott MA, Reid IR. Osteoporos Int. 2009 Aug;20(8):1407-15. Epub 2008 Dec 20. PMID: 19101755 Sixty-three elderly participants were randomized to three regimens of vitamin D supplementation: a 500,000-IU loading dose; the loading dose plus 50,000 IU/month; or 50,000 IU/month. CONCLUSIONS: Large loading doses of vitamin D(3) rapidly and safely normalize 25OHD levels in the frail elderly. Monthly dosing is similarly effective and safe, but takes 3-5 months for plateau 25OHD levels to be reached.

    Evidence from clinical trials shows, with a wide margin of confidence, that a prolonged intake of 10,000IU/d of vitamin D3 poses no risk of adverse effects for adults, even if this is added to a rather high physiologic background level of vitamin D. Vitamin D and cancer mini-symposium: the risk of additional vitamin D. Vieth R.\nAnn Epidemiol. 2009 Jul;19(7):441-5. Epub 2009 Apr 11. PMID: 19364661 doi:10.1016/j.annepidem.2009.01.009

    Together, the earlier data and the data of Heaney et al indicate that an oral dose of vitamin D2 or vitamin D3 would lead to a comparable increase in circulating 25(OH)D concentrations in children and adults when the initial 25(OH)D3 concentrations in the groups are similar and when equivalent oral vitamin D doses expressed per kilogram body weight/d are given.

    Randomized comparison of the effects of the vitamin D3 adequate intake versus 100 mcg (4000 IU) per day on biochemical responses and the wellbeing of patients. Vieth R, Kimball S, Hu A, Walfish PG. Nutr J. 2004 Jul 19;3:8. PMID: 15260882 doi:10.1186/1475-2891-3-8 CONCLUSION: The highest AI for vitamin D brought summertime 25(OH)D to >40 nmol/L, lowered PTH, and its use was associated with improved wellbeing. The 100 mcg/day dose produced greater responses. Since it was ethically necessary to provide a meaningful dose of vitamin D to these insufficient patients, we cannot rule out a placebo wellbeing response, particularly for those on the lower dose. This work confirms the safety and efficacy of both 15 and 100 mcg/day vitamin D3 in patients who needed additional vitamin D.
