Vitiligo is a skin disease of still unclear, multifactorial aetiology. Numerous autoimmunological disturbances observed in vitiligo may be suggestive of a systemic nature of the disease. Since the research into immunological and metabolic abnormalities gives evidence that they may also be present in vitiligo, it seems essential that any disturbances or abnormalities should also be searched for in the patients affected with the condition. Metabolic changes which take place in both the liver and spleen are also worth the interest.
Aim & Scope: The aim of the study was to assess the liver and spleen function parameters in the children hospitalized in Department of Dermatology Medical University of Lublin.
Material and Methods: The study included 34 vitiligo patients and 35 healthy individuals, aged 7-15 years old. We examined those children who had the active phase of vitiligo, in which exacerbation of skin lesions had a history of 6 months. Liver and spleen ultrasound examination included their size and parenchyma assesment. In order to assess the liver and spleen functioning the following accessory examinations were performed: blood test, transaminases, electrophoresis of proteins, lipid profile, autoantibodies, HCV antibodies.
Results: The values of the liver size were not significantly different between the study and control groups. The ultrasonografic pictures of the spleen did not revealed any abnormalities in the size and structure of the organ. The concentration of HDL-cholesterol was significantly lower whereas the concentration of LDL-cholesterol was significantly higher in vitiligo patient in comparison with the healthy group. The value of the LDL/HDL ratio was significantly higher in vitiligo patients.
Comments:
• Performed investigations are indicative of lipid disturbances in children affected with vitiligo.
• However, the ultrasound examination did not reveal any abnormalities with reference to the size and structure of both the liver and spleen. Neither did biochemical investigations reveal any disfunctions of the liver and spleen.
• Since there were no structural and functional abnormalities in the liver and spleen it seems plausible that lipid disturbances in vitiligo may result from genetic defect or some auto-cytotoxic events taking part in the condition pathogenesis.
• The nature of the conducted research is preliminary and it requires further long-term studies, which would include a wider variety of studied subjects as well as more numerous groups.

Vitiligo

• Stigmatization

• Decreased quality of life

• Obsession and phobia

•Europe about 0.5-2% (in Denmark- 0.38%; in Turkey- 0.15-0.32%)•India 0.005% (in Calcuta- 0.46%; in Surat- 1.13%; in Gujarat- 8.8%)•China 0.093%•The United States 1%

Vitiligo

• A skin disease of still unclear, multifactorial aetiology. • Numerous autoimmunological disturbances observed

in vitiligo may give grounds to conclude that it is a systemic disease.

• Since the research into immunological and metabolic abnormalities gives evidence that they may also be present in vitiligo, it seems essential that any disturbances or abnormalities should also be searched for in the patients affected with vitiligo.

• Metabolic changes which take place in both the liver and spleen are also worth the interest .

Page 5: Hepato-splenic abnormalities in vitiligo - do they exist?

Liver

• Detoxication,

• Synthesis of carbohydrates, proteins, lipids

• May be disturbed in vitiligo patients.

Spleen

• Participates in immunological processes,

• Works as a filter for the mature blood cells, i.e. erythrocytes and platalets.

• Among other things, spleenomegaly is also observed in inflammations, metabolic diseases as well as in cancer .

The aim of the study

• The aim of the study was to assess the liver and spleen function parameters in the children hospitalized in Department of Dermatology Medical University of Lublin.

• The study included those children who had the active phase of vitiligo, in which exacerbation of skin lesions had a history of 6 months.

• Caucasian children aged 7-15• Duration of vitiligo: from 6 months to 9 years, mean

duration - 2.1 years• Vitiligo type: Vulgaris and Focal• Without mucosal involvement• Family history of vitiligo: 3 patients• Autoimmune thyroid disease: 1 patient;

TSH: within normal limits• No diabetes, glucose intolerance

• Liver ultrasound examination included its size and parenchyma assesment.

• In order to determine the liver size, measurements in three vertical lines were performed:-in the right front axillary line;

-in the central line of the right clavicle;-in the central line of the body in the section going through the long axis of the aorta.

Page 15: Hepato-splenic abnormalities in vitiligo - do they exist?

• Spleen ultrasound examination included its size and parenchyma assesment .

• In order to determine the size of the spleen, the measurement in two dimensions, longitudinal and transverse were performed.

Conclusions

• Performed investigations are indicative of lipid disturbances in children affectedwith vitiligo.

• However, the ultrasound examinationdid not reveal any abnormalities with reference to the size and structure of both the liver and spleen. Neither did biochemical investigations revealany disfunctions of the liver and spleen.

Page 27: Hepato-splenic abnormalities in vitiligo - do they exist?

• Since there were no structuraland functional abnormalities in the liver and spleen it seems plausible that lipid disturbances in vitiligo may result from genetic defect or some auto-cytotoxic events taking part in the condition pathogenesis.

• The nature of the conducted researchis preliminary and it requires furtherlong-term studies, which would includea wider variety of studied subjectsas well as more numerous groups.
