Quantitative determination of LP-X, abnormal serum low density lipoprotein, was performed on the sera of 620 patients with jaundice in two medical centers, one in Oklahoma City, Oklahoma, and the other in Birmingham, England. The results of serial assays over a period of 5 to 8 days after patient admission to hospital or after onset of jaundice, if this occurred in hospital, correlated best with the type and management of jaundice. In some cases of early cholestatic disease of extrahepatic origin LP-X may be absent, but after the observation period it was found that only 1 of 81 (98%) patients with obstruction of the extrahepatic bile duct system remained negative. Of the remainder, 74 (91%) had or developed levels of LP-X exceeding 300 mg per 100 ml. In addition, 43 (88%) of 49 subjects followed serially showed increases in LP-X concentration, with no change in 3 patients. Of 539 subjects with intrahepatic disease, 14 (26.5%) were LP-X positive and 27 (19.4%) of these had initial LP-X levels higher than 300 mg per 100 ml. During the follow-up period, 35 (74%) of 47 patients with intrahepatic disease showed a reduction of LP-X; of the remaining 12 patients 4 had mitochondrial antibody-positive primary biliary cirrhosis, and 6 had severe cholestasis associated with acute infectious hepatitis and high aspartate transaminase levels. Similar figures for alkaline phosphatase showed less consistent changes during the follow-up period. In this retrospective appraisal the trends and absolute levels of LP-X, in addition to the use of similarly followed levels of the routine liver function tests, allowed better differentiation of jaundice requiring surgical correction from that remediable by medical means exclusively than did the use of the routine liver function tests alone. In addition, LP-X is specific for liver dysfunction, whereas other routine liver function tests are not.

The values of serum concentration of alkaline phosphatase and of bone isoenzyme fraction, determined by thermal inactivation of serum were followed up in 42 patients with chronic renal insufficieny, treated with hemodialysis for a long time. The authors found that the elevation of those valuse correlates with the degree of the manifested changes in the bone skeleton. Attention is paid to the fact that the determination of bone and liver isoenzymes of alkaline phosphatase could help the earlier diagnosis of bone changes and infectious hepatitis, both being frequent complications in patients treated with hemodialysis.

The diagnosis of infectious hepatitis was made in a football player at East Carolina University in the 3rd week of fall practice in 1974. Clinical and laboratory evaluation of all persons involved in the program followed. All participants received immune serum globulin. No further cases were identified. Serum chemistry and enzyme levels were determined under uncontrolled conditions. Lactate dehydrogenase and alkaline phosphatase were generally elevated.

BACKGROUND Drug-induced liver injury (DILI) can present clinically as a spectrum that includes asymptomatic elevation of transaminases, acute or chronic hepatitis, and acute liver failure. Idiosyncratic DILI is more likely to affect individuals with comorbidities, and to have a wide range of clinical presentations. Although antibiotics are associated with DILI, the fluoroquinolone, ciprofloxacin, is a rarely reported cause. Two cases of idiosyncratic DILI following ciprofloxacin treatment are described, including a review of the literature. CASE REPORT Case 1: A 35-year-old man was treated with ciprofloxacin for periorbital cellulitis. On the second day of ciprofloxacin treatment, he developed abdominal pain, nausea, vomiting and increased serum levels of liver transaminases, aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Further investigations excluded infectious hepatitis, autoimmune disease, or structural liver disease. Exclusion of other causes of DILI and cessation of ciprofloxacin resulted in clinical improvement and normalization of liver function tests (LFTs). Case 2: An 82-year-old man was treated with ciprofloxacin for osteomyelitis. On the tenth day of ciprofloxacin treatment, he developed jaundice and abnormal LFTs, including increased AST, ALT, alkaline phosphatase (ALP), and total bilirubin. Further investigations excluded infectious hepatitis, autoimmune disease, or structural liver disease. Exclusion of other causes of DILI and cessation of ciprofloxacin resulted in clinical improvement and normalization of LFTs. CONCLUSIONS Idiosyncratic DILI due to ciprofloxacin treatment is rare. These two cases have shown that timely diagnosis and discontinuation of ciprofloxacin can prevent the progression of DILI, reduce liver damage, and reduce mortality rates from DILI.
