Insights
This study reports on three siblings with prolidase deficiency (PD), a rare genetic disorder. Despite limited resources, tailored therapies led to significant improvement in their non-healing ulcers and other symptoms.
Area of Science:
- Genetics and Metabolic Disorders
- Dermatology
- Rare Diseases
Background:
- Prolidase deficiency (PD) is an ultra-rare autosomal recessive disorder.
- It stems from impaired collagen degradation, causing proline-rich dipeptide accumulation.
- Clinical manifestations include skin ulcers, distinctive facial features, and intellectual deficits.
Observation:
- A cluster of three siblings (17, 19, 20 years) presented with classic PD symptoms.
- They exhibited non-healing leg ulcers, hypertelorism, depressed nasal bridge, intellectual impairment, and high-arched palate.
- The patients had limited access to specialized diagnostics and treatments due to socioeconomic factors.
Findings:
- Despite challenges, a tailored, improvised therapy combining three modalities was implemented.
- Patients demonstrated remarkable clinical progress and improvement in their condition.
- The study highlights successful management strategies in resource-limited settings.
Implications:
- This case series underscores the importance of recognizing PD even in resource-limited environments.
- Improvised therapeutic approaches can yield significant positive outcomes for rare diseases.
- Further research into accessible treatments for PD is warranted.
Abstract:
Prolidase deficiency (PD) is an exceptionally rare autosomal recessive disorder characterized by impaired collagen degradation, leading to the accumulation of proline-containing dipeptides. We report a cluster case of three siblings aged 17, 19, and 20 years, comprising of two sisters and one brother, who presented with non-healing ulcers on their shins and feet along with facial features of hypertelorism, depressed nasal bridge, reduced intellectual function, and high-arched palate. History and clinical features were consistent with PD. Due to the rarity of the disease and low socioeconomic background of the patients, specialized investigations or treatments were either unavailable or inaccessible. Furthermore, surgical intervention was ill-advised. Despite these challenges, patients were treated using improvised tailored therapy using three different modalities and showed remarkable progress. The evaluation and management took place at the dermatology unit of Hayatabad Medical Complex in Peshawar, Pakistan.
