Pattern of Mucocutaneous Manifestations in Patients With Chronic Kidney Disease in New Vally and Assuit (Hospital Based Study) .

Chronic kidney disease (CKD) is defined as abnormalities of kidney structure or function , present for > 3 months , with implications for health . chronic kidney disease is classified based on cause , Glomerular Filtration Rate category (G1-G5) , and Albuminuria category ( A1-A3) , abbreviated as CGA . (Michel et al.,2023).

Chronic kidney disease (CKD) affects up to 13% of the population and may progress to kidney failure and death. Some risk factors for chronic kidney disease are well known such as high blood pressure and diabetes. There is some evidence that inflammatory skin diseases such as eczema and psoriasis may also increase the risk of chronic kidney disease . (Schonmann et al.,2021).

Skin serves as the mirror of underlying systemic problems. The early diagnosis of subtle cutaneous clinical pointers often helps in identifying renal disorders, obviating the delay in diagnosis and treatment. Cutaneous changes can be observed from the beginning of renal impairment until the evolution to terminal stage . ( Vivek et al,2021) Most patients with severe chronic kidney disease progress to end stage renal disease (ESRD). Cutaneous manifestations are common in all stages of chronic kidney disease particularly towards end stage renal disease . (Rattan et al.,2018).

The prevalence of chronic kidney disease is increasing, and the incidence and prevalence of associated skin diseases will also increase. Their early recognition and treatment to reduce morbidity and mortality are essential . (Timur et al,2014) Many factors are involved in the pathogenesis of the cutaneous manifestations of end stage renal disease , including electrolyte imbalance, buildup of uremic substances, and comorbid disease (Goldman et al,2012).

There are two main categories of the cutaneous manifestations of chronic kidney diseases: nonspecific and specific.
