Clinical and histological skin changes were studied in 30 cases of chronic renal failure. Generalised pruritus and numbness were the commonest symptoms observed in 14 and 11 patients respectively. Ichthyotic skin changes of varying degree were observed in 27 cases and hyperpigmentation of sun-exposed skin was seen in 11 cases. Half and half nails were seen in 4 cases only. Cutaneous changes like pruritus, pallor, scaling and hair loss correlated strongly with the severity of renal failure. Histopathological examination revealed epidermal and dermal changes, latter were seen only in moderate to severe cases of renal failure.

| Introduction|| |
Chronic renal failure (CRF) is associated with a variety of nonspecific clinical and histological changes in skin, regardless of its aetiology. Primary disease process leading to CRF and various treatment modalities like drugs, dialysis, and renal transplantation can also produce skin lesions in patients of renal insufficiency. ,
There are remarkably few studies on cutaneous manifestations of CRF.  Here we report our observations on cutaneous changes in 30 patients of CRF.
| Material and Methods|| |
Thirty cases of CRF were evaluated. A detailed history was taken and complete clinical examination was carried out in all cases. Relevant haematological investigations were carried out and skin biopsy was performed in all cases from apparently normal looking skin over the back. All patients were taken up for study before commencement of dialysis and none of the patients had undergone renal transplantation. Severity of CRF was assessed by calculating creatinine clearance and graded as follows
Mild CRF - Creatinine clearance more than 30 ml/minute
Moderate CRF - Creatinine clearance 10-30 ml/minute
Severe CRF - Creatinine clearance less than 10 ml/minute
Nineteen men and 11 women in age range 14-67 years were included in the present study. Majority of the patients (17) were in their 3rd and 4th decades of life. Duration of CRF after diagnosis varied from 3 month to 2 years.
| Results|| |
Generalised pruritus was the commonest symptom observed in 14 patients. Numbness/tingling and poor wound healing were recorded in 2 patients, both of them having diabetes mellitus as the underlying pathology. Two patients complained of easy bruising and recurrent bacterial infections. lchthyotic skin changes of varying degree were observed in 27 patients. Hyperpigmentation of skin more marked in sun-exposed parts of body was seen in 11 patients. Sparse body/scalp hair and purpuric skin lesions were noticed in 6 and 2 patients respectively. None of the patients had features of calcinosis cutis or uraemic frost. Nail examination revealed pallor in most of the cases. Half and half nails were seen in 4 patients. Dystrophic nail changes were observed in 6 cases. Clubbing and Beau's lines were noticed in 3 and 2 patients respectively.
An attempt was made to correlate cutaneous sign and symptoms with the severity of renal failure [Table - 1]. Pruritus, pallor, and scaling were seen predominantly in moderate and severe cases of CRF. Manifestations like hair loss, and half and half nails were observed in moderate to severe cases only.
Histological examination of skin revealed epidermal changes like hyperkeratosis, thinning of prickle cell layer, flattening of rete ridges, and pigment accentuation in basal cell layer, which did not correlate well with the severity of CRF. Dermal changes were seen in moderate to severe cases only and comprised of endothelial prominence of superficial blood vessels, sparse appendages, hyalinisation of collagen, and round cell infiltration in upper dermis [Table - 2].
| Comments|| |
Generalised pruritus recorded in 47% of patients in our study is reported to be the most common cutaneous symptom in CRF, with a prevalence of 15%-49% in renal disease.  Diffuse hyperpigmentation accentuated in sun-exposed areas, seen in 36% of our patients is characteristic of uraemic patients. 
The half and half nail which had been emphasized as a marker of uraemia consists of proximal white band and distal red brown band occupying 20% to 60% of nail plate. These have been reported in 20% to 35% of patients with CRF, as compared with 2% of the general hospital population.  This findings was seen in 13% of patients in our study.
Histopathologic changes in skin consistent with our findings have been described in renal failure.  An association between uraemia and cutaneous microangiopathy has also been reported.
