A Late Complication of Covid-19 Pandemic: Rickets

Öz

Objective: Sunlight is the most important source of vitamin D. Obesity is an important risk factor for rickets. During pandemic periods, such as the Covid 19 pandemic, children cannot be exposed to enough sunlight due to the closure of schools, curfews, and other limitations. They are prone to obesity due to malnutrition and inactivity. This study was conducted to show that rickets can develop in children during a pandemic period and to draw attention to the problem. Materials and Methods: Patients who visited a polyclinic-emergency clinic in the 3-month period before pandemic restrictions started (in the early stages of the pandemic) and patients who visited in the 3-month period when there were restrictions (in the late period of the pandemic) were evaluated for rickets. The frequency of rickets along with calcium, phosphorus, alkaline phosphatase, parathormone and vitamin D levels were compared. Result: While 49/100,000 cases of hypocalcemia were detected in the pre-pandemic period, 123/100,000 cases of hypocalcemia were detected during the pandemic period. Compared to the pre-pandemic period, a 2.5-fold increase was detected in hypocalcemia during the pandemic period. Conclusion: There may be an increase in cases of rickets during periods of long-term restrictions, such as in pandemic periods. During these periods, children should be evaluated for rickets, preventive measures should be taken, and those who develop a disease should be treated.

Covid-19 Pandemisinin Geç Dönem Bir Komplikasyonu: Raşitizm

Öz

Amaç: D vitamini çeşitli gıdalardan ve deride bulunan 7-dehidrokolesterolden güneş ışığı etkisiyle elde edilir. Obezite raşitizm için önemli bir risk faktörüdür. Covid 19 gibi pandemi dönemlerinde okulların kapalı olması, sokağa çıkma yasakları ve diğer sınırlamalar nedeniyle çocuklar yeterince güneş ışığına maruz kalamamaktadırlar. Dengesiz beslenme ve hareketsizlik nedeniyle obeziteye yatkın olmaktadırlar. Bu çalışma pandemi döneminde çocuklarda raşitizm gelişebileceğini göstermek ve bu duruma dikkat çekmek amacıyla yapılmıştır. Gereç ve Yöntem: Covid-19 pandemisinin erken dönemlerinde kısıtlamaların olmadığı ilk 3 aylık dönemdeki poliklinik ve acil başvurusu olan hastalar ile pandeminin geç döneminde kısıtlamaların olduğu üç aylık dönemdeki hastalar raşitizm yönünden değerlendirildi. Raşitizm sıklığı, kalsiyum, fosfor, alkalen fosfataz, parathormon ve vitamin D seviyeleri kıyaslandı. Bulgular: Pandemi kısıtlamaları öncesi dönemde 49 / 100 000 hastada hipokalsemi saptanırken, pandemi döneminde 123 /100 000 hipokalsemi vakası tespit edilmiştir. Hipokalsemi vakalarında pandemi kısıtlamalarından önceki döneme göre pandemi döneminde 2,5 katlık artış tespit edilmiştir. Sonuç: Pandemi boyunca olduğu gibi uzun süreli kısıtlamaların uygulandığı dönemlerde raşitizm vakalarında artış olabilmektedir. Bu dönemlerde çocuklar raşitizm yönünden değerlendirilmeli, önleyici tedbirler alınmalı ve hastalık tablosu gelişenler tedavi edilmelidir.
