Alcohol-induced diseases of the liver, such as fatty liver, hepatitis and cirrhosis with the potential development of hepato-cellular carcinoma can cause many effects on the skin. Even though they are not caused by excessive alcohol alone, but also by other diseases of the liver or other diseases of internal organs, an experienced person will be able to carry out specific diagnostic procedures. Skin symptoms due to liver diseases include 1. Vascular changes, such as spider nevi, teleangiectasias and palmar erythema. 2. Nail changes, particularly white nails. 3. Changes of the mucous membranes, i.e. glossy tongue. 4. Changes due to altered hormones, particularly gyneco-mastia, female distribution of hair and testicular atrophy and 5. Changes in the color of the skin like icterus and melanosis cutis. Rarely pruritus and other diseases of the skin are seen, such as porphyria cutanea tarda, which is often caused by an altered liver function. In the final stages of alcoholism, the neglect of personal hygiene particularly of the skin is evident (cutis vagantium). Since the exact mechanism of the skin symptoms remains obscure, it is difficult to evaluate the significance. Most often they do not correlate with the severity of the liver disease.

By screening 204 diabetes patients, a male with age 38 was found to have increased C-peptide levels in plasma (over 6 ng/ml) and urine (430 microg/day), both of which were the highest among the screened subjects. He developed type 2 diabetes at age 31, without history of obesity (weight was 52 kg and height 170 cm). He had bilateral testicular atrophy. Fasting plasma glucose level was 160 mg/dl and HbA1c was 8% at age 38. There was hypertriglycemia (290-662 mg/dl). There were no abnormal peaks of IRI or CPR in the serum fractionated by gel filtration (Biogel P 30). Molar ratio of p-CPR/s-IRI was 10.8. Islet cell antibody, anti-insulin binding antibody and anti-insulin receptor antibody were negative. LSH and FSH were both elevated, and free testosterone was decreased. TSH and Leptin levels were elevated. Other laboratory data were within normal range. CT scan revealed fatty liver and horse-shoe kidney. These clinical pictures do not match the criteria to known syndromes associated with diabetes. Although the single case report is insufficient to discuss the C-peptide mechanism of action, this case may give us a hint to understand an aspect of the pathophysiology of C-peptide's bioactivity dysfunction.

Refsum disease is caused by a deficiency of phytanoyl-CoA hydroxylase (PHYH), the first enzyme of the peroxisomal alpha-oxidation system, resulting in the accumulation of the branched-chain fatty acid phytanic acid. The main clinical symptoms are polyneuropathy, cerebellar ataxia, and retinitis pigmentosa. To study the pathogenesis of Refsum disease, we generated and characterized a Phyh knockout mouse. We studied the pathological effects of phytanic acid accumulation in Phyh(-/-) mice fed a diet supplemented with phytol, the precursor of phytanic acid. Phytanic acid accumulation caused a reduction in body weight, hepatic steatosis, and testicular atrophy with loss of spermatogonia. Phenotype assessment using the SHIRPA protocol and subsequent automated gait analysis using the CatWalk system revealed unsteady gait with strongly reduced paw print area for both fore- and hindpaws and reduced base of support for the hindpaws. Histochemical analyses in the CNS showed astrocytosis and up-regulation of calcium-binding proteins. In addition, a loss of Purkinje cells in the cerebellum was observed. No demyelination was present in the CNS. Motor nerve conduction velocity measurements revealed a peripheral neuropathy. Our results show that, in the mouse, high phytanic acid levels cause a peripheral neuropathy and ataxia with loss of Purkinje cells. These findings provide important insights in the pathophysiology of Refsum disease.
