Dermatologic Manifestations of Chronic

Kidney Disease

Moderators : Dr. Basappa Dr. RaviPresented by : Dr. Chandan

Page 2: Skin in ckd   Dr.chandan

Background and Classification

• 1. Dermatologic manifestations of diseases associated with the development of

ESRD

• 2. Dermatologic manifestations of uremia

• 3. Dermatologic disorders associated with renal transplantation.

Page 3: Skin in ckd   Dr.chandan

• 1. Dermatologic manifestations of diseases

associated with the development of ESRD

• DM – Dermopathy, Necrobiosis, Acanthosis nigricans, Kyrle disease

• Connective tissue disorders • Fabrys disease : Angiokeratomas• Tuberous sclerosis : Adenoma sebaceum

Ash-leaf macule Periungual fibromas Shagreen patch

Background and Classification

• 1. Dermatologic manifestations of diseases associated with the development of

ESRD

•2. Dermatologic manifestations of uremia

• 3. Dermatologic disorders associated wit renal transplantation.

Cutaneous manifestations of Uremia• Xerosis • Pruritis• Pigmentary alteration• Nail Changes• Hair Changes• Acquired perforating disorder (Kyrle disease) • Bullous disease of dialysis • Calcinosis cutis (metastatic) • Calciphylaxis • Nephrogenic systemic fibrosis • Porphyria cutanea tarda

Page 6: Skin in ckd   Dr.chandan

Xerosis

• Most common cutaneous abnormality

• Is predominantly seen over the extensor surfaces of the forearms, legs and thighs.

• The abdomen and chest may show fine scaling

Page 8: Skin in ckd   Dr.chandan

Uremic Pruritis

• One of the most characteristic and annoying cutaneous symptoms of CRF

• Incidence : 50-90 %• Mechanisms :

Page 9: Skin in ckd   Dr.chandan

Uremic Pruritis - Mechanisms :

– Xerosis – Decreased transepidermal elimination

of pruritogenic factors – Hyperparathyroidism – Hypercalcemia – Hyperphosphatemia – Elevated histamine levels – Increased dermal mast cell proliferation – Uremic sensory neuropathy – Middle molecule theory

Page 10: Skin in ckd   Dr.chandan

Uremic Pruritus -Treatment :

– Emperical– Topical Steroids– UV phototherapy– Capsaicin– Erythropoietin– Naltrexone, Gabapentin– HD, Transplant– Primerose oil, Tacrolimus ?

Page 11: Skin in ckd   Dr.chandan

Pigmentary changes

• Pallor – Anemia• Yellow hue – Carotenoids• Hyperpigmentation - increase in

poorly dialyzable beta-melanocyte stimulating hormone

Page 12: Skin in ckd   Dr.chandan

Purpura / Echymosis / Easy bruising

• Defects in primary hemostasis like increased vascular fragility

• Abnormal platelet function • Use of heparin during dialysis are

the main causes of abnormal bleeding in these patients

Page 13: Skin in ckd   Dr.chandan

Nail changes

• Lindsay's nails (half and half nails, prevalence 15-50 % )

• Others – Koilonychia – Subungual hyperkeratosis – Onycholysis – Splinter hemorrhages – Brown nail bed arcs

Page 15: Skin in ckd   Dr.chandan
Page 16: Skin in ckd   Dr.chandan

Yellow nail syndrome (YNS) is triad of yellow nails, lymphedema, and respiratory tract involvement

Page 17: Skin in ckd   Dr.chandan

Hair abnormalities

• Sparse body hair and diffuse alopecia with dry, lusterless hair

• Decreased secretion of sebum• Chronic telogen effluvium • Drugs – Heparin / Statins /

Antihypertensives

Page 18: Skin in ckd   Dr.chandan

Calcific Uremic Arteriolopathy (Calciphylaxis)

• Characterized by calcification, intimal hypertrophy, and thrombosis of small vessels, which results in necrotizing, nonhealing ulcers.

• Infectious complications – non healing ulcers

• 1-year survival rate of 45% • Treatment : Wound Care

Intensified HD Discontinuation vitamin D analogs Urgent Parathyroidectomy Calcimimetic cinacalcet Hyperbaric O2

Acquired Perforating Dermatosis ( APD )

• Papulonodular hyperkeratosis with central crust

• Excessive scratching + diabetic vasculopathy - dermal necrosis- eliminated through the epidermis

• Kyrle’s disease• Elastosis Perforans serpiginosa• Perforating folliculitis• Reactive perforating collagenosis

Page 22: Skin in ckd   Dr.chandan

Porphyria Cutanea Tarda

• Commonly presents as bullae on the dorsal surfaces of the hands and feet

• Sporadic form of PCT occurs in approximately 5% of patients on dialysis; this form is caused by increased uroporphyrin concentrations and can be triggered by ingestion of alcohol, estrogens or iron and by chronic infections such as hepatitis B, hepatitis C or HIV

• Treatment : Unsatisfactory

Page 23: Skin in ckd   Dr.chandan

Bullous Disease of Dialysis

• Syndrome of cutaneous fragility and blistering • Sun-exposed skin, most often on the dorsal

hands• Resembles Porphyria• Plasma porphyrin levels are normal or only

minimally elevated • Mechanical fragility of skin subjected to

sunlight and incidental trauma • Rx : Protect from sunlight, Avoid Trauma• Drug induced pseudoporphyria - Nabumetone,

Furosemide, Tetracycline, Nalidixic acid

Page 26: Skin in ckd   Dr.chandan

Nephrogenic fibrosing dermopathy (NFD)

• Recentle described - 1997 • Resembles Scleromyxedema• Progressive development of painful,

erythematous, sclerotic dermal plaques, usually pruritic on the arms and legs, with sparing of the head and neck

• HPE - proliferation of fibroblasts in the dermis and subcutaneous septae accompanied by increased dermal and septal collagen and mucin

• No Effective Treatment

Nephrogenic systemic fibrosis in a 56-year-old patient.

(A)The typical red discoloration and orange-peel thickening

of the skin (peau d'orange) of the upper arm with a 'woody' texture.

(B) Secondary thrombosis of the arteriovenous fistula in the left arm (arrow) owing to progressive tightening of the skin.

(C) The patient's left hand is severely affected with limited

movement of the digital joints, which resulted in contractures.

Page 28: Skin in ckd   Dr.chandan

Iatrogenic manifestations

• Arterial steal syndrome -pain and numbness. Prolonged ischemia may result in digital gangrene, peripheral neuropathy, or cutaneous atrophy

Page 29: Skin in ckd   Dr.chandan

• 3. Dermatologic disorders associated with

renal transplantation.

InfectionsDrugs – Steroids, ImmunosuppresantsMalignancies

Page 30: Skin in ckd   Dr.chandan

Skin changes in Acute Renal Failure

• 1. Edema• 2. Uremic Frost

Page 31: Skin in ckd   Dr.chandan

Uremic Frost

Was a frequent In the pre-dialysis era

The frost consists of a white or yellowish coating of urea crystals on the beard area and other parts of the face, neck and on the trunk.

It is due to eccrine deposition of urea crystals on the skin surface of patients with severe uremia
