Generalized pustular psoriasis is a rare form of psoriasis that is sometimes associated with extracutaneous manifestations. Evidence for biliary involvement has been suggested in isolated cases. We investigated the prevalence and nature of liver abnormalities occurring in this disease. Twenty-two patients consecutively admitted for generalized pustular psoriasis who underwent liver biological tests at the time of the attack and during the following weeks were included. Twenty patients (90%) had at least one abnormal biological liver parameter. Eleven patients (50%) had pronounced abnormalities: jaundice (4/22), gammaglutamyl transferase higher than 5 times the normal value (10/22), alkaline phosphatase higher than twice the normal value (7/22), and/or aminotransferases higher than 3 times the normal value (7/22). These abnormalities returned to normal range at the time of remission of pustular psoriasis, suggesting that severe liver abnormalities could be associated with severe cutaneous disease. Neutrophilic cholangitis was observed on liver biopsy. Persistent magnetic resonance cholangiopancreatography features similar to those observed in sclerosing cholangitis were found in 3 of the 4 patients studied. No causal factor other than pustular psoriasis could be identified. In conclusion, our results demonstrate the high frequency of liver abnormalities in patients with generalized pustular psoriasis. Biliary involvement related to neutrophilic cholangitis should be added to the spectrum of extracutaneous manifestations of this disease, and physicians should be aware of such a complication.

Summary.We assessed the role of spinal magnetic resonance imaging (MRI) and bone densitometry as prognostic factors in patients with asymptomatic stage I multiple myeloma (MM) and negative skeletal survey. 55 consecutive patients underwent spinal MRI and 41 of them underwent bone densitometry by dual-energy X-ray absorptiometry (DEXA).Spinal MRI studies showed evidence of bone marrow involvement in 17/55 patients (31%). A diffuse pattern was present in three patients and a focal pattern in 14 patients, nine of them with only one nodular lesion. During a median follow-up of 25 months, 10 patients had disease progression, 8/17 patients with abnormal MRI and 2/38 patients with normal MRI. Median time to disease progression was not reached in both groups but was significantly different for patients with normal and those with abnormal patterns on MRI (P < 0·0001). Lumbar BMD was only slightly decreased compared with normal people (median lumbar Z score ¹ 0·43) and was not of prognostic value. Using a multivariate analysis the only two independent significant prognostic parameters were abnormal MRI (P < 0·001, HR 30·4, 95% CI 4·3-213) and bone marrow plasmacytosis > 20% (P ¼ 0·004, HR 16·4, 95% CI 2·6-104).Thus, spinal MRI but not bone densitometry, appeared to be justified in patients with stage I asymptomatic MM and negative skeletal survey.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
