A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

Chronic hepatitis C virus (HCV) infection is associated with several extrahepatic syndromes. The principal types of renal disorders associated with chronic HCV infection are cryoglobulinemia or noncryoglobulinemic membranoproliferative glomerulonephritis (MPGN). Interferon-alpha (IFN-alpha) may precipitate or exacerbate the occurrence of MPGN. Our patient was a 32-year-old man who tested positive for HCV in July 1997. The patient was treated with IFN-alpha in another medical center for 6 months because his liver biopsy showed chronic active hepatitis. In December 1998, he applied to our clinic for a follow-up examination. The level of aspartate aminotransferase (AST) was 44 U/L, and that of alanine aminotransferase (ALT) was 69 U/L. HCV RNA was positive in serum, and chronic HCV infection was detected by liver biopsy. IFN-alpha therapy (5 million U/day) was administered for 6 months longer. In May 1999, the patient came to our polyclinic with edema of the feet and legs. We detected proteinuria, serum cholesterol of 269 mg/dl, AST of 50 U/L, ALT of 41 U/L, serum total protein of 3.4 g/dl, serum albumin of 1.2 g/dl, positive cryoglobulin, and urine protein of 9.84 g/day. Cryoglobulinemic MPGN was suspected and kidney biopsy was performed, resulting in a diagnosis of minimal change disease (MCD).

Treatment of chronic hepatitis C in renal-transplant (RT) recipients with alpha-interferon is associated with a high rate of acute rejection. We therefore evaluated the biochemical, virological, histological efficacies, as well as the safety of one year ribavirin monotherapy in 16 HCV-(+) RNA (+) RT patients (group A) matched to 32 HCV-(+) RNA (+) RT patients (group B) who did not receive ribavirin. Ribavirin was initially started at a daily dose of 1000 mg and then adapted to hemoglobin level. Ribavirin monotherapy was associated with a significant decrease in AST, ALT and gamma glutamyl transpeptidase levels. Serum creatinine decreased as well. When proteinuria was present (n = 5), this decreased or disappeared. There was no significant changes in HCV viremia. The histological analysis of liver biopsies revealed a significant progression in liver fibrosis with no improvement in inflammation scores. There was a significant decrease in hemoglobin levels, despite an important support by recombinant erythropoeitin. However, in three cases, ribavirin therapy had to be stopped. In group B, after 1 year of follow up, there was a significant increase in serum ALT and creatinine values. Proteinuria decreased in only 2 of 12 patients. In conclusion, one year ribavirin therapy in HCV-(+) RNA (+)ve RT has no impact upon liver histology, although it improves liver enzyme levels. It impact upon renal function remains unknown. Nevertheless when proteinuria is present it disappears.

The activities of the enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LD), creatine kinase (CK), amylase (AMS) and angiotensin converting enzyme (ACE) have been used to assess the toxic effects of xenobiotics that have hypoglycaemic action in hepatic, pancreatic, renal and muscle tissue. Using a validated experimental model of diabetes mellitus in rats, we ascertained whether this syndrome itself affected the serum activities of these enzymes over a 53-day period. Levels of hepatic enzymes AST, ALT and ALP were higher in the streptozotocin (STZ)-diabetic rats (group D), but were controlled by insulin therapy (group DI). AMS was reduced in group D and unchanged in group DI rats. Proteinuria was detected 1 day after STZ administration and partially controlled by insulin (group DI); its early presence in group D rats, and the lack of any change in serum ACE in this group, indicates that proteinuria is the better marker for microangiopathy. Microscopic examination of liver, kidney, heart and skeletal muscles (soleus and extensor digitorum longus) revealed various alterations in group D rat tissues, which were less pronounced in group DI. The liver, pancreas and kidney tissue-damage was consistent with the altered serum levels of AST, ALT, ALP and AMS and proteinuria. We conclude that: (i) rigorous control is required when these serum-enzyme levels are used as indicators of tissue toxicity in experimental diabetes, and (ii) LD, CK and bilirubin serum levels, which are unaffected by diabetes, can be used when testing effects of xenobiotics on tissues.

The explosive RDX (hexogen, cyclonite) is usually used for the production of C-4 explosive. The rare occurrence of accidental and intentional RDX intoxications has been reported during manufacturing process or in wartime. In this article, the authors report 5 cases of accidental oral RDX poisoning. On admission, observed signs and symptoms included repetitive generalized tonic-clonic convulsions, postictal coma, lethargy, confusion, hyperreflexia, postictal amnesia, nausea, vomiting, abdominal tenderness, sinusal tachycardia, dysrhythmia with frequent ventricular premature beats, generalized muscle spasms, and myoclonus. Leukocytosis, mild anemia, methemoglobinemia, elevated levels of blood glucose, serum aspartate transaminase, alanine transaminase, lactic dehydrogenase, creatine phosphokinase, amilase, hypokalemia, metabolic acidosis, proteinuria, glucosuria, and myoglobinuria were also noted. Plasma RDX concentrations were 268 to 969 ng/mL at 3 hours of ingestion. For management, supportive and symptomatic measures were taken. Whole-bowel irrigation might have been an effective therapeutic procedure due to probable slow gastrointestinal absorption of RDX. Three patients who developed severe metabolic acidosis underwent urgent hemodialysis. All patients were discharged 7 to 21 days after admission without any sequelae. Plasma RDX levels were strongly correlated with the clinical and laboratory manifestations. The available toxicological data on this rare accidental poisoning are reviewed in light of the literature.

The aim of this laboratory-based study was to investigate some of the toxic effects induced by the venom from Hemiscorpious lepturus (H. lepturus). For this aim, pharmacological, histological, biochemical methods as well as complete blood cell count were used to assess these toxic actions. In addition, in vitro haemolysis studies on human washed blood suspension and cytotoxicity on cultured fibroblasts were also undertaken. In vitro pharmacological test was made on rat isolated ileal segment. To this end, the effects of the venom on the contractile responsiveness to acetylcholine were recorded using F30 transducer and Darco chart recorder. For assessment of the haemolytic potency, varying concentrations (2, 10, 20 and 40 microg/ml) of the venom were added to 0.5 ml of 5% washed human blood and after 30 min, 2, 4, 8, 12 and 24h of exposure, the degree of lysis (extent of redness developed in the supernatant solution after centrifugation) were measured by ELISA method. Cytotoxicity potential of the venom was assessed by trypan blue exclusion test. The venom (0.1, 1 and 10 microg/ml) was mixed with confluent fibroblast cell culture and the extent cytotoxicity was assessed microscopically. In vivo studies were conducted by a subcutaneous administration of sub-lethal dose (10 microg) of the venom and after 7 days the skin, at the site of injection, and kidney samples were stained by H & E method and examined microscopically. In addition, biochemical assessments including measurement of serum aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and amylase levels and urine analysis were made. The results showed that the venom prevented the relaxation phase of the acetylcholine-induced contractions on the isolated ileal segments and finally produced sustained spasmodic contractions. This spasmodic action was abolished by 1 microM atropine. The venom produced haemolysis of red blood cells in a concentration-dependent and duration-of-exposure manner, with 100% of haemolysis produced after 24h following exposure to 40 microg/ml of venom. While cultured fibroblasts cells were more sensitive and disintegrated after 15 min of exposure to 1 microg/ml of the venom. Histological findings showed evidences of excessive inflammatory responses accompanied with signs of necrosis in the skin at the site of injection as well as structural damage in the nephrones. There was a significant rise in the serum enzymes. In addition, the number of the RBCs were reduced. The urine showed positive readings for proteinuria, blood and intact RBCs. The overall results suggest that the venom from H. lepturus primarily is a cytotoxic agent and has haemolytic, nephrotoxic and to some extent hepatotoxic activity.

A 49-year-old woman with a history of chronic hepatitis C virus infection and Hashimoto disease was admitted to our hospital because of proteinuria, hematuria, purpura, and edema in the lower extremities. Laboratory data on admission revealed proteinuria (0.2 g/day), microscopic hematuria (3+) with RBC casts, renal dysfunction(serum creatinine 1.4 mg/dl), positive anti nuclear antigen (x640, speckled type), hypocoplementemia, mixed cryoglobulinemia (type III), and hepatitis C virus infection (AST 45 IU/l, ALT 33 IU/l). MPO-ANCA level was found to be high (356 EU). In renal biopsy, most glomeruli showed crescentic formation with the weak deposition of IgG, IgM, and C3 in the mesangial area and along the capillary wall. She was diagnosed as having systemic vasculitis associated with MPO ANCA. Methylprednisolone pulse therapy followed by oral prednisolone (40 mg/day) effectively normalized MPO ANCA level. It has been reported that ANCA is found in patients with HCV-associated mixed cryoglobulinemia. Therefore, in chronic hepatitis C patients with systemic vasculitis, we should consider the possibility of ANCA-related microscopic polyangiitis and make a correct diagnosis by renal biopsy.

A 64-year-old man visited our clinic with a 9-day history of headache and fever. He had frequent, severe, electric shock-like pain in his left eye, forehead, and scalp. The body temperature was 37.1 degrees. Cranial nerve functions were intact. Limb weakness and stiff neck were absent. There were injection of the conjunctiva, a red rash on the trunk, and an eschar in the axilla. Abnormal laboratory findings included AST 40 IU, ALT 44 IU, CRP 16.0 mg/dl, WBC 11,090/microl, and proteinuria. CT scan was unremarkable. The cerebrospinal fluid (CSF) showed 2 polymorphs/microl, 6 lymphocytes/microl, 65 mg/dl of glucose, and 42 mg/dl of protein. A diagnosis of scrub typhus was made. Treatment with minocycline brought about prompt disappearance of the fever and dramatic clinical improvement. Increased antibody titers confirmed the diagnosis. Although almost all patients present with high fever and severe headache, only a small number of patients have CSF pleocytosis. The present case illustrates that pain in scrub typhus is, on rare occasions, indistinguishable from trigeminal neuralgia. Neurologists should have a high index of suspicion in patients with fever and headache during the epidemic season and should be familiar with the systemic symptoms and signs.

Clinical manifestations of liver involvement in multiple myeloma (MM) are uncommon. Rare cases of MM present as acute liver disease. We report a case of a 55-year-old woman with MM who presented with painless jaundice, mild pruritus, and abnormal liver function tests resembling acute cholestatic hepatitis without the stigmata of chronic liver disease. Initial laboratories included elevated liver function tests (aspartate aminotransferase 74 U/L and alanine aminotransferase 45 U/L) and an elevated white blood cell count of 19,600 cells/microL with 33% circulating plasma cells. Myeloma parameters demonstrated an immunoglobulin G lambda monoclonal protein with lambda light-chain Bence-Jones proteinuria. Bone marrow was hypercellular with 70% plasmacytosis. A liver biopsy revealed a diffuse portal and sinusoidal infiltration of plasma cells with lambda light-chain restriction. In this report, we review the literature of liver involvement in MM.

Thrombocytopenia-absent radius (TAR) syndrome affects 0.5-1/100,000 live births. We describe, to the best of our knowledge, the sixth patient with TAR to experience a successful pregnancy and the first such case complicated by severe pre-eclampsia. The diagnosis of pre-eclampsia was made at 33 weeks by blood pressure and proteinuria. A further decline in platelets suggested, but could not reliably confirm, severe pre-eclampsia until she experienced persistently elevated aspartate aminotransferase levels. Repeat cesarean delivery was performed at 33 4/7 weeks' gestation. Obstetrical conditions characterised by thrombocytopenia may present diagnostic challenges and should be considered in the differential diagnosis of thrombocytopenic exacerbations in TAR syndrome.
