Abstract:
Myringosclerosis is the final stage of the middle ear lamina propria inflammation or trauma; it starts with collagen production in excess amounts in the lamina propria of the middle ear mucosa. Then, hyalinization and calcification occur. Later on, metaplasia of bone or cartilage can occur. A similar sequence occurs with hyperparathyroidism in chronic kidney disease. This study is aimed to detect the prevalence of myringosclerosis in patients of our hemodialysis (HD) unit and find out any association between hyperparathyroidism and myringosclerosis in chronic HD patients. A total number of 86 patients were selected according to the inclusion criteria. They were divided into two groups: Group 1 (58 patients myringosclerosis free patients on regular HD), Group 2 (28 patients myringosclerosis-positive patients on regular HD). No statically significant difference was found in serum parathyroid hormone levels between the two studied groups. Serum creatinine was significantly higher in Group 2, serum ferritin was significantly lower in Group 2, and mean corpuscular volume of red blood cells was highly significantly lower in Group 2. Myringosclerosis affects 32% of our HD patients and we could not detect any strong correlation between myringosclerosis and hyperparathyroidism.
Insights
Myringosclerosis, a middle ear condition, affects 32% of hemodialysis patients. This study found no strong link between myringosclerosis and hyperparathyroidism in these patients.
Area of Science:
- Otolaryngology
- Nephrology
- Pathology
Background:
- Myringosclerosis involves collagen overproduction, hyalinization, calcification, and potential metaplasia in the middle ear.
- A similar pathological sequence is observed in hyperparathyroidism associated with chronic kidney disease.
Purpose of the Study:
- To determine the prevalence of myringosclerosis in hemodialysis (HD) patients.
- To investigate the association between hyperparathyroidism and myringosclerosis in chronic HD patients.
Main Methods:
- 86 chronic HD patients were evaluated.
- Patients were categorized into two groups: myringosclerosis-negative (n=58) and myringosclerosis-positive (n=28).
- Serum parathyroid hormone, creatinine, ferritin, and red blood cell mean corpuscular volume were analyzed.
Main Results:
- Myringosclerosis was present in 32% of the studied HD patients.
- No statistically significant difference in serum parathyroid hormone levels was found between groups.
- Significantly higher serum creatinine, lower serum ferritin, and significantly lower mean corpuscular volume were observed in the myringosclerosis-positive group.
Conclusions:
- Myringosclerosis is prevalent in 32% of chronic HD patients.
- No strong correlation was found between myringosclerosis and hyperparathyroidism in this cohort.
- Further research may explore the association with other biochemical markers.
