Insights
Pityriasis Alba (PA) in children is linked to lower levels of hemoglobin, zinc, copper, and magnesium. Sun exposure and skin type are also identified as key risk factors for this common skin condition.
Area of Science:
- Pediatric Dermatology
- Nutritional Biochemistry
- Clinical Research
Background:
- Pityriasis Alba (PA) is a prevalent pediatric skin condition with various contributing factors.
- Understanding the biochemical profile associated with PA is crucial for effective management.
Purpose of the Study:
- To investigate serum levels of trace elements (copper, zinc, magnesium) and hemoglobin (Hb) in children diagnosed with Pityriasis Alba.
- To identify potential nutritional deficiencies and their correlation with PA.
Main Methods:
- A case-control study involving 110 children (55 with PA, 55 controls) aged 6-16.
- Analysis of sociodemographic data, clinical history, and dermatological examination.
- Biochemical assessment of serum trace elements and hemoglobin levels using SPSS software.
Main Results:
- Significantly lower levels of hemoglobin, serum ferritin, copper, zinc, and magnesium were observed in the PA group compared to controls.
- Zinc deficiency was associated with a >15-fold increased risk of PA.
- Reduced Hb levels increased PA risk by over ninefold (OR 9.6).
Conclusions:
- Pityriasis Alba is associated with deficiencies in hemoglobin, serum zinc, ferritin, copper, and magnesium.
- Sun exposure and skin phototype are significant risk factors for developing PA.
- These findings highlight the importance of nutritional status and environmental factors in PA pathogenesis.
Background:
Pityriasis Alba (PA) is a common skin disorder affecting the children and it has multiple risk factors.
Objectives:
To assess the serum levels of trace elements (copper, zinc, and magnesium) and hemoglobin (Hb) level in patients with PA.
Method:
This is a case control study; 110 participants (55 cases and 55 controls) were recruited from pediatric dermatology and family medicine clinics, Cairo university hospitals. Patients were allocated into two groups, PA group (randomly selected male and female children age group (6-16) with PA lesions) and a matched control group. Full history was taken including sociodemographic data, present history of the lesions. Full general and dermatological examination was done. Blood samples were taken to asses iron and trace elements levels. The gained measures were analyzed by (SPSS) program version 22.
Results:
This study showed that Hb levels, serum ferritin, copper, zinc and magnesium were significantly lower in PA group. There was statistically significant difference between both cases and controls regarding trace elements (copper, zinc, and magnesium) with (p value was 0.000, 0.000 and 0.003) respectively. Zinc deficiency increased the risk by more than 15 folds. Also, there was statistically significant difference between both groups regarding Hb levels and serum ferritin (p value was 0.000). The reduced Hb level increases the risk of PA by more than nine folds (OR 9.6) CONCLUSION: PA is associated with reduced levels of Hb, serum zinc, ferritin, copper and magnesium; sun exposure, skin phototype were found to be important risk factors for PA.
