BACKGROUND

Platelet rich plasma (PRP) is increasingly used as an adjunct treatment for androgenetic alopecia (AGA). PRP preparation involves anticoagulant tubes, such as PRP kits or regular tubes such as EDTA. Studies have shown that platelet concentration in PRP correlates with the growth factors present. However, there is limited data regarding the platelet yield across different anticoagulant tubes. This study will aid in the use of EDTA tube as an alternative to the commercially available PRP kits.

OBJECTIVE

This study aims to determine the platelet concentration level obtained in EDTA tubes versus the commercially available PRP kit in patients with AGA.

METHODOLOGY

This was a cross-sectional, quantitative study in 27 adult males with AGA. The venous blood extracted were placed in EDTA and PRP kit tubes and were centrifuged. A hemoanalyzer was used to obtain the platelet concentration levels. Statistical analyses using paired t-test was performed using the STATA MP Software.

RESULTS

Comparative analyses indicated that the mean difference in platelet concentration between the PRP kit and EDTA was -472.67 (95% Cl = -575.40 to - 369.93). Thus, the mean platelet concentration (t=-9.46, p=0.001) was statistically different between the two groups with a significantly higher mean platelet concentration with EDTA as compared to the PRP kit.

CONCLUSION

The platelet concentration levels obtained from the EDTA tubes were higher than the PRP kit. Thus, the EDTA tube may be a good alternative to the costly commercially available PRP kit.

Juvenile Dermatomyositis (JDM) is a rare type of idiopathic inflammatory myopathy affecting children, characterized by symmetric proximal muscle weakness and pathognomonic cutaneous manifestation such as heliotrope rash and Gottron papules. In the Philippines, there are only 40 cases from 2011 to 2022. It is an autoimmune disease, although several studies have associated its onset to the presence of systemic infections. In cases complicated by systemic infection, early initiation of comprehensive treatment is essential in order to achieve remission.

This is a case of a 2-year old female presenting with a 2 month history of erythematous macules over the metacarpophalangeal (MCP), proximal interphalangeal (PIP), distal interphalangeal joints (DIP), and knees, nailfold changes, and facial erythema on sun exposure. This was associated with decreased activity, inability to walk continuously, and symmetric proximal muscle weakness. Skin punch biopsy was done which revealed interface vacuolar dermatitis, alcian blue stain positive. Laboratories revealed elevated ANA, aldolase, LDH, and SGPT which were all consistent with dermatomyositis. Patient was started on oral prednisone, hydroxychloroquine and topical corticosteroids. Notably, the patient was also diagnosed with pulmonary tuberculosis and ascariasis. Thus, she was also started on anti-Kochs regimen and mebendazole. After 2 months of steroid therapy and hydroxychloroquine, there was improvement in cutaneous lesions with significant increase in activity and mobility.

In a country where pulmonary tuberculosis and ascariasis is common, it is of utmost importance to probe for underlying infections which may occur with or may be contributory to the onset of juvenile dermatomyositis.
