Hypervitaminosis D rarely causes hypercalcemia: new concept subclinical intoxication

Year 2018, , 165 - 167, 15.08.2018
https://doi.org/10.18521/ktd.396175

Abstract

Aim: D vitamins have been
used by physicians and the public more often than usual in recent years. D
vitamin intoxication 25 OH vitamin D level> 150 μg / L calcium level>
10.5 mg / dl is defined as. In clinical practice, hypercalcemia may not be
observed at very high 25 OH vitamin D levels. The reason for this is unknown.
The purpose of this  study is to
investigate 
the percentage
of hypercalcemia in patients with very high 25 OH D levels.

Material-Methods: Between
January 1, 2016 and October 31, 2017, 22996 patients who were referred to
hospital and examined 25 OH vitamin D levels from all patients were screened at
the Dicle University Medical Faculty Hospital. Patients with 25 OH vitamin D
levels> 150 μg / L were included in the study. The calcium, phosphorus,
creatinine, albumin and parathormone values of these patients, if any, were checked.
Rates of hypercalcemia in patients with hypervitaminosis D were evaluated. The
vitamin D preparations they used were recorded. Vitamin D was measured by HPLC
method. Ethical committee opinion was taken for the study.

Results: The number of patients
with vitamine D> 150 μg / L was approximately 1/1000 (0.0013%). Age 56 ± 20
(24-90). More frequent in females 21 K 6 E (78/12%). 25 OH Vitamin D 184.81 ±
35.37 (150.51-279.64) μg /L, and D vitamine levels after replacement were
measured after 2.10 ± 1.58 months. Calcium 9.48 ± 0.52 (8.4-10.9) mg /dL.
Percentage of hypercalcemia in patients with vitamin D> 150 μg /L was 3.70.







Conclusion: As a
result, very high levels of vitamin D do not show toxicity. When vitamin D
level is above the level of toxicity, calcium and phosphorus control should be
performed. Very high vitamin D levels are often attributed to too much ampoule use. Close follow-up and appropriate dose treatment of the
patients will solve this problem. There is a need for studies involving a large
number of patients with randomized controlled, multicenter, genetic and
metabolic parameters for the correct definition of vitamin D toxicity.

Hipervitaminoz D Nadiren Hiperkalsemi Yapar: Subklinik İntoksikasyon

Year 2018, , 165 - 167, 15.08.2018

Abstract

Amaç: D vitamini son yıllarda hekimler ve halk tarafından genelde gereğinden fazla kullanılmaktadır. D vitamini intoksikasyonu 25 OH vitamin D düzeyi >150 µg/L kalsiyum düzeyi >10.5 mg/dl olarak tanımlanmaktadır.  Klinik pratikte çok yüksek 25 OH vitamin D değerlerinde hiperkalsemi gözlenmeyebilir. Bunun nedeni bilinmemektedir. Bu çalışmada amacımız çok yüksek 25 OH vitamin D düzeyi olan hastalardaki hiperkalsemi yüzdesini ortaya çıkarmaktır.

Materyal-metod: Dicle Üniversitesi Tıp Fakültesi Hastanesine  1 ocak 2016 ile 31 Ekim 2017 tarihleri arasında tüm bölümlere başvuran ve yatan hastalardan 25 OH vitamin D düzeyine bakılan  22996 hasta tarandı. 25 OH vitamin D düzeyi >150 µg/L olan hastalar çalışmaya alındı. Bu hastaların eğer varsa veri tabanımızdaki kalsiyum, fosfor, kreatinin, albumin ve parathormon değerlerine bakıldı. Hipervitaminoz D hastalarındaki hiperkalsemi oranlarına bakıldı. Kullandıkları D vitamini preperatı kaydedildi. D vitamini HPLC  yöntemiyle ölçülmüştü. Çalışma için etik kurul görüşü alındı.

Sonuçlar: D vitamini >150 µg/L olan hasta sayısı 32 saptandı(32/22996 yaklaşık 1/1000). Yaş 56 ±20 (24-90), Kadınlarda daha sık gözlendi.  21 Kadın, 6 Erkek  (%78/12 ). 25 OH Vitamin D 184.81±35.37(150.51-279.64) µg/L  Kalsiyum 9.48±0.52(8.4-10.9) mg/dL. D vitamini >150 µg/L olan hastalardaki hiperkalsemi yüzdesi 3.7 saptandı.

Sonuç olarak çoğu hastada çok yüksek D vitamini düzeyleri toksikasyonu göstermemektedir. D vitamini düzeyi toksikasyon düzeyinin üzerinde saptandığında kalsiyum ve fosfor kontrolü yapılmalıdır. Çok yüksek D vitamini düzeyi genelde gereğinden çok fazla ampul formu kullanımına bağlı görülmektedir. Hastaların yakın takibi ve uygun dozda tedavisi bu problemi çözecektir. D vitamini toksikasyonunun doğru tanımı için randomize kontrollü, çok merkezli, genetik ve metabolik parametreleri içeren çok sayıda hasta içeren çalışmalara ihtiyaç vardır.
