Painless Jaundice Caused by Clonorchis sinensis Infection: A Case Report.

A man with only yellowing of the skin and eye sclera was diagnosed with clonorchiasis, which rarely manifested jaundice as the initial symptom. However, because of a lack of evidence for a diagnostic gold standard, the time until definitive diagnosis was more than a week. The diagnostic process relied on inquiring about the patient's history, including the place of residence, dietary habits, and symptoms, as well as on serological findings, an imaging examination, and pathological findings. MRCP and CT results showed mild dilatation of intrahepatic ducts and increased periductal echogenicity. The eggs were ultimately found in stool by water sedimentation method after the negative report through direct smear. DNA sequencing of PCR production of the eggs demonstrated 98-100% homology with ITS2 of Clonorchis sinensis. After anti-parasite medical treatment, the patient's symptoms were gradually relieved. Throughout the diagnostic procedure, besides routine examinations, the sedimentation method or concentration method could be used as a sensitive way for both light and heavy C. sinensis infection in the definite diagnosis.

Rare cause of jaundice in a post liver transplant patient.

A hepatitis B virus carrier suffering from acute flare of chronic hepatitis B infection underwent deceased-donor liver transplantation. He was put on the immunosuppressive agent tacrolimus. On routine follow-up, he was found to have abnormal liver function. Computed tomography scan of the abdomen did not show any dilatation of the biliary system. Liver biopsy showed scattered microabscesses, and a microgranuloma was detected. Endoscopic retrograde cholangiography was performed and a biliary anastomotic stricture (BAS) was noted. In addition, the Chinese liver fluke, Clonorchis sinensis, was discovered. Balloon dilatation and stenting were performed. The patient was given a course of praziquantel. His liver function improved and normalized. We present the case of a liver transplant recipient with cholangitis caused by C. sinensis infestation and infection and biliary obstruction resulting from BAS.

[A man in his thirties with icterus and itching]. / En mann i 30-årene med icterus og kløe.

BACKGROUND: We present a patient from South-East Asia who has been living in Norway for five years. He was referred to our department with jaundice caused by opisthorchiasis/clonorchiasis. This reason for jaundice is highly unusual in Europe. Worldwide, however about 35,000,000 people are infected. CASE PRESENTATION: A male in his thirties, originally from South-East Asia, experienced diffuse itching for five weeks and painless jaundice for two weeks. Blood samples showed increasing cholestasis. Abdominal ultrasound, MRCP and computed tomography showed no sign of bile duct obstruction or liver tumour. Serological tests and liver biopsy revealed no infectious or autoimmune liver disease. ERCP showed normal bile ducts, but large quantities of typical hookworms in the duodenum. Stool samples showed at least one egg typical of Opisthorchis/Clonorchis and a large quantity of hookworm eggs. We interpreted these findings as parasite-induced obstruction of some of the small bile ducts. The patient recovered completely after treatment with Praziquantel. INTERPRETATION: Jaundice due to bile duct obstruction by opisthorchiasis/clonorchiasis is a well-known problem in South-East Asia. It may become more common in Europe as well as a result of increasing migration. Treatment with Praziquantel is simple and effective.

A cross-sectional study for algorithm in diagnosing simple uncomplicated malaria in children in health facilities without laboratory backup in Nigeria.

AIMS AND OBJECTIVES: The objective of this study was to determine an algorithm for malaria diagnosis using presenting signs and symptoms of children (aged 0-13 years) with uncomplicated malaria in Gwagwalada Area Council of Abuja, Nigeria. MATERIALS AND METHODS: A validated questionnaire was used to obtain relevant data from 400 children diagnosed presumptively of simple malaria by clinicians and 400 other children of similar sex and age considered as not having malaria. Giemsa-stained thick blood films were used to determine parasitaemia. Data obtained was analysed using Epi-Info version 3.3.2. RESULTS: Thirty-eight per cent of children with presumptive diagnosis of malaria had parasitaemia. Fever, rigor, vomiting, jaundice, pallor and spleen enlargement had significant statistical relationship with parasitaemia on bivariate analysis, but only fever (p=0.00), rigor (p=0.00), vomiting (p=0.00), and pallor (p=0.00) maintained the relationship when subjected to logistic regression analysis. But these symptoms individually had low sensitivity and/or specificity. Candidate algorithms (combinations of symptoms) were then successively subjected to bivariate, logistic and validity analyses. Fever with vomiting gave the highest sensitivity (56.2%), specificity (76.4%) and PPV (60.0%) and were therefore adopted as the algorithm of choice. CONCLUSION AND RECOMMENDATIONS: Children presenting with fever and vomiting without any other obvious cause in health facilities without laboratory support in the research area should receive antimalarial treatment, to help reduce the malaria scourge. This algorithm should be field-tested and if found reliable should be adopted to ease the problem of malaria diagnosis in peripheral health facilities.

Abnormal findings on dipstick urinalysis of out-patients with malaria in Abakaliki, Nigeria.

BACKGROUND & OBJECTIVES: Malaria, one of the major health challenges of the tropics affecting about 500 million people, particularly the children and pregnant women have been associated with changes in urine compositions. The present study was undertaken to document the urinary abnormalities in malaria patients based on malaria species and the level of malaria parasitaemia. METHODS: Febrile patients (n = 365) with positive Giemsa - stained blood films for malaria recruited from Outpatient Department of Ebonyi State University Teaching Hospital, Abakaliki participated in the study. Patients were classified into two categories (+ and ++) based on parasite density. Apparently healthy individuals (n = 81), without malaria parasite on both thick and thin films of comparable age and gender acted as control group. Urine sample (10 ml) was collected from each participant and analysed using standard laboratory methods and techniques. RESULTS: Seventy - four (20.3%) of the patients had Plasmodium falciparum malaria. Although all the urine parameters were higher in the malarial patients in comparison to the control, only bilirubinuria and urobilinogenuria were statistically significant (p <0.05). Also, bilirubinuria, urobilinogenuria, haematuria and proteinuria were significantly (p < 0.05) higher in P. falciparum infection than in infections with other malaria species, but only in P. falciparum infection, bilirubinuria and urobilinogenuria were significantly (p < 0.05) higher at higher parasitaemia. CONCLUSION: Even though positive blood film for malaria parasite remains the gold standard for the diagnosis of malaria, urinary abnormalities, such as bilirubinuria, urobilinogenuria, proteinuria and haematuria may aid in identifying patients with severe malaria parasitaemia, especially the falciparum malaria.

Ursodeoxycholic acid and artesunate in the treatment of severe falciparum malaria patients with jaundice.

BACKGROUND AND AIMS: Plasmodium falciparum (PF) infection can lead to severe complications. Ursodeoxycholic acid (UDCA) is increasingly used for the treatment of cholestatic liver diseases. The present study aims to determine the effects of combined UDCA and artesunate compared to placebo and artesunate on the improvement of liver tests in severe PF jaundiced patients. METHODS: All severe PF jaundiced patients, aged > or = 15 years and diagnosed as having severe malaria according to WHO 2000 criteria, were enrolled. Patients with evidence of biliary obstruction, other cholestatic liver diseases and those who were pregnant were excluded. Patients were randomized to receive either oral UDCA or placebo for 2 weeks in additional to artesunate. All patients were admitted for at least 14 days to monitor the result of the treatment. RESULTS: Seventy-four severe PF malaria patients with jaundice were enrolled. Both groups had similar demographic and laboratory tests, with the exception being more males in the UDCA group than in the placebo group (P = 0.04). The median of percentage change of total bilirubin and aminotransferase levels at the end of weeks 1, 2, 3 and 4 showed no difference between the two groups. Only the median of percentage change of alkaline phosphatase at the end of week one compared with the baseline values showed less increment in the UDCA group than in the placebo group (P = 0.04). No serious adverse events were seen during the 4 weeks of follow up. CONCLUSIONS: In severe PF malaria patients with jaundice, combined therapy with UDCA and artesunate is safe, but does not significantly improve liver tests compared to placebo and artesunate.

Jaundice with hepatic dysfunction in P. falciparum malaria.

UNLABELLED: To evaluate the frequency and severity of jaundice with hepatic dysfunction in Plasmodium (P.) falciparum malaria in adult patients admitted in the hospital. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: The Infectious Diseases Unit and Medical Wards at Rashid Hospital, Dubai, United Arab Emirates, from January 2005 to December 2007. METHODOLOGY: This study included 105 adult patients who fulfilled the inclusion criteria. The diagnosis of P.falciparum malaria was confirmed by examination of thin and thick film stained with Leishman's stain. Other laboratory investigations included full blood count, liver function tests, blood urea, electrolytes, serum creatinine, reticulocyte count, blood sugar, viral hepatitis serology and coagulation profile. Patient with significant clinical/biochemical hepatic dysfunction were also subjected to ultrasonic examination of abdomen. RESULTS: On clinical examination, 23% patients were found to be jaundiced. Serum alanine amino transferase (ALT) level was above the reference range in 67.6%, but in only 11.4%, ALT was more than 3 times of normal level. Serum bilirubin was found to be higher than normal level in 81%, however, only in 23% of the patients, Serum bilirubin was >3mg/dl. Predominantly conjugated hyperbilirubinemia was observed in patients with high ALT. There was no significant change in serum albumin and prothrombin time. In comparison to normal bilirubin level, the patient with bilirubin >3mg/dl had high frequency of raised ALT 87.5% vs. 45% (p<.0001), thrombocytopenia 91.6% vs. 65% (p<.01), anemia 70.8% vs. 25% (p<.05) and renal impairment 50% vs. 20% (p>.05). Overall, 5 (4.7%) patients died and mortality rate was high among the patients with bilirubin level>3mg/dl than with normal bilirubin level 4 (16.6%) vs 1 (5%). CONCLUSION: Hepatic dysfunction in acute P.falciparum malaria ranged from mild elevation of liver enzymes to acute hepatitis (ALT>10 times of normal level). It indicates severe illness with high frequency of complication and mortality rates.

Malarial hepatopathy in falciparum malaria.

OBJECTIVE: To evaluate the clinical, biochemical and sonographic changes in patients with falciparum malaria and jaundice. STUDY DESIGN: A case series. PLACE AND DURATION OF STUDY: This study was conducted at Medical Unit-I (Ward 5), Jinnah Postgraduate Medical Centre, Karachi, from January 2006 to November 2007. METHODOLOGY: A total of 62 adult patients, regardless of age and gender, with peripheral blood film evidence of falciparum malaria, who had jaundice, were included. Any patient with evidence of infection with Plasmodium vivax or other causes of liver disease (e.g. viral hepatitis, cirrhosis, portal hypertension, amoebic liver abscess, unexplained hepatomegaly, ascites, history of alcoholism, taking hepatotoxic drugs, past history of jaundice) was excluded on the basis of history, relevant clinical examination and investigations. RESULTS: Age of the patients ranged from 13-48 years (mean 26.04+/-8.33). All patients were febrile and icteric, with pallor in 67.7%, hepatomegaly in 30.6%, splenomegaly in 70.9% and impaired consciousness in 20%. Serum bilirubin levels ranged from 3 to 24 mg%. Thirty two (51.6%) had serum bilirubin 3-6 mg%, 20 (32.2%) had 6-10 mg% and 10 (16.1%) had >10 mg%. ALT levels ranged from 20-870 IU/L and AST levels 24-1210 IU/L respectively. INR ranged from 1-1.3. Twenty eight patients (45%) had predominantly conjugated or mixed hyperbilirubinemia and serum transaminases were more than three times normal. Ultrasonography revealed hepatomegaly with decreased echogenicity in 22 (35.4%), splenomegaly in 48 (77.4%) and both hepatomegaly and splenomegaly in 16 (25.8%). Gallbladder wall thickness was increased in 5 (8.06%) patients. There was no evidence of biliary dilatation. CONCLUSION: A significant percentage of patients having falciparum malaria with jaundice fulfill the criteria for malarial hepatopathy. It should be considered in patients presenting with acute febrile illness with jaundice so that specific treatment can be given.

Jaundice in falciparum malaria; changing trends in clinical presentation--a need for awareness.

OBJECTIVES: To describe the clinical characteristics, laboratory parameters and prognostic factors in patients with falciparum malaria (FM) with jaundice. METHODS: A cross-sectional comparative study was conducted at the Department of Medicine, medical unit II, Jinnah Postgraduate Medical Centre, Karachi. Adult patients with jaundice and smear positive plasmodium falciparum infection, who fulfilled the inclusion criteria were selected for the study from amongst all cases of FM who presented during the study period. Patients were divided in to two groups on the basis of rising bilirubin and adverse outcome. The data was analyzed on SPSS ver 12. Results were expressed as, percentages, mean and standard deviations. P-value < 0.05 was taken as significant. RESULTS: Among 76 patients of FM, 35 (46.05%) developed jaundice. Fifteen (42.86%) patients had bilirubin 3-10 mg/dl while 20 (57.14%) had bilirubin > 10 mg/dl. Comparative analysis of the groups showed that elevation of ALT and AST was modest in comparison with conjugated hyperbilirubinaemia while prolonged duration of illnes impaired consciousness, hepatomegaly, acute renal failure with deranged renal parameters, low platelet counts and high parasite density were significantly associated with rising bilirubin and adverse outcome. Twenty-one (60%) patients recovered completely while 14(40%) succumbed to the disease. CONCLUSION: FM is one of the causes of severe jaundice in adults in this part of the world. This presentation of complicated FM needs to be recognized globally in order to institute prompt and specific therapy. Delayed diagnosis and inappropriate treatment is the leading cause of complications and increased mortality in FM.

Hepatobiliary complications of alveolar echinococcosis: A long-term follow-up study.

AIM: To determine the long-term hepatobiliary complications of alveolar echinococcosis (AE) and treatment options using interventional methods. METHODS: Included in the study were 35 patients with AE enrolled in the Echinococcus Multilocularis Data Bank of the University Hospital of Ulm. Patients underwent endoscopic intervention for treatment of hepatobiliary complications between 1979 and 2012. Patients' epidemiologic data, clinical symptoms, and indications for the intervention, the type of intervention and any additional procedures, hepatic laboratory parameters (pre- and post-intervention), medication and surgical treatment (pre- and post-intervention), as well as complications associated with the intervention and patients' subsequent clinical courses were analyzed. In order to compare patients with AE with and without history of intervention, data from an additional 322 patients with AE who had not experienced hepatobiliary complications and had not undergone endoscopic intervention were retrieved and analyzed. RESULTS: Included in the study were 22 male and 13 female patients whose average age at first diagnosis was 48.1 years and 52.7 years at the time of intervention. The average time elapsed between first diagnosis and onset of hepatobiliary complications was 3.7 years. The most common symptoms were jaundice, abdominal pains, and weight loss. The number of interventions per patient ranged from one to ten. Endoscopic retrograde cholangiopancreatography (ERCP) was most frequently performed in combination with stent placement (82.9%), followed by percutaneous transhepatic cholangiodrainage (31.4%) and ERCP without stent placement (22.9%). In 14.3% of cases, magnetic resonance cholangiopancreatography was performed. A total of eight patients received a biliary stent. A comparison of biochemical hepatic function parameters at first diagnosis between patients who had or had not undergone intervention revealed that these were significantly elevated in six patients who had undergone intervention. Complications (cholangitis, pancreatitis) occurred in six patients during and in 12 patients following the intervention. The average survival following onset of hepatobiliary complications was 8.8 years. CONCLUSION: Hepatobiliary complications occur in about 10% of patients. A significant increase in hepatic transaminase concentrations facilitates the diagnosis. Interventional methods represent viable management options.

Hepatocyte dysfunction and hepatic encephalopathy in Plasmodium falciparum malaria.

BACKGROUND: According to the WHO, signs of hepatic dysfunction are unusual, and hepatic encephalopathy is never seen in malaria. However, in recent years, isolated cases have been reported from different parts of world. AIM: To identify the evidence for hepatocyte dysfunction and/or encephalopathy in jaundiced patients with falciparum malaria. DESIGN: Prospective observational study. METHODS: We studied 86 adult patients of both sexes who had malaria with jaundice (serum bilirubin > 3 mg%). The main outcome measures were: flapping tremor, deranged psychometric test, level of consciousness, serum bilirubin level, serum aspartate transaminase (AST) and alanine transaminase (ALT) levels, blood ammonia level, viral markers for hepatitis, ultrasonography of liver and gall bladder and electroencephalography (EEG). RESULTS: The range of serum bilirubin was 3-48.2 mg% (mean +/- SD 10.44 +/- 8.71 mg%). The ranges of AST and ALT levels were 40-1120 IU/l (294.47 +/- 250.67 IU/l) and 40-1245 IU/l (371.12 +/- 296.76 IU/l), respectively. Evidence of hepatic encephalopathy was seen in 15 patients. Asterexis was observed in 9 patients, impaired psychometric tests in 12 and altered mental state in 13. Arterial blood ammonia level was 120-427 meq/l (310 +/- 98.39 meq/l). EEG findings included presence of large bilateral synchronous slow waves, pseudo burst suppression and triphasic waves. Four patients died due to multiple organ dysfunction; the others made rapid recoveries. DISCUSSION: There is strong evidence of hepatocyte dysfunction and hepatic encephalopathy in some of these patients, with no obvious non-malarial explanation. Current guidelines may need to be revised.

Complications and mortality patterns due to Plasmodium falciparum malaria in hospitalized adults and children, Rourkela, Orissa, India.

Of 1857 Plasmodium falciparum malaria patients hospitalized from 1995 to 1998, 608 had severe malaria and 83 died. Acute renal failure, jaundice and respiratory distress were common in adults whereas children frequently had severe anaemia. Cerebral malaria occurred equally in adults and children but recovery from coma was quicker in children. Multiple complications caused high mortality in adults.

Systemic infections affecting the liver. Some cause jaundice, some do not.

The patient who has clinical jaundice, abnormal results on liver function tests, or both presents a difficult diagnostic challenge. Many infectious diseases affect the liver, and the extent of involvement determines the degree of clinically apparent jaundice. Some diseases that affect the liver minimally cause no jaundice at all. An important clue to the cause of the disorder is the pattern of abnormal results on liver function tests. Increased alkaline phosphatase predominates with Q fever, secondary or tertiary syphilis, clonorchiasis, and hepatic candidiasis, while elevated levels of serum transaminases characterize viral hepatitis, leptospirosis, mononucleosis syndromes, legionnaires' disease, typhoid fever, toxic shock syndrome, and yellow fever. Increases in serum bilirubin are typical with jaundice caused by clostridial myelonecrosis, severe bacterial sepsis, and relapsing fever (borreliosis). These findings together with the patient's history, physical findings, and basic laboratory tests provide a presumptive diagnosis in most cases.

Clinical characteristic of amoebic liver abscesses in the North of Iraq.

OBJECTIVE: The purpose of the study was to find out the clinical characteristic of amoebic liver abscesses in this area, the simplest method for diagnosis and to determine the effectiveness of treatment by metronidazole therapy proved by disappearance of symptoms and regression in the size of the abscesses by ultrasound. METHODS: We studied prospectively all cases of suspected liver abscesses admitted to our unit over 2 years (1990 & 1991). A special case sheet was prepared. Daily follow up of patients was carried out in hospital for at least 10 days. Patients were later followed up by ultrasound after discharge. We compared the rate of infection from the hospital records over the last 9 years up to the end of 1998. RESULTS: We found the clinical features of the disease similar to those mentioned in essential text books of medicine, except that pain is not always epigastric while fever may be absent and hepatomegaly is not marked. Ultrasound is a simple, cheap diagnostic test, which is available. Metronidazole is an effective treatment and none of the patients required an invasive method for diagnosis or treatment. None had secondary bacterial infection. CONCLUSION: Amoebic liver abscess if untreated is a grave disorder. We concluded that recognizing the disorder clinically and proving it by ultrasound is the main method for diagnostic confirmation. Following the hospital records of the last 9 years, it seems that the rate of infection is declining in this area.

[Moroccan experience in the surgical treatment of multiple hydatid cysts in the liver]. / L'expérience marocaine dans le traitement chirurgical des kystes hydatiques multiple du foie: à propos de 94 cas.

We studied 94 cases of multiple hydatid cysts in the liver, over a period of ten years. These cases accounted for 31.3% of all cases of hydatid cysts treated surgically in the Visceral Surgery Department of Avicenne Military Hospital in Marrakech. In these patients, who were often young and male, the principal symptoms were pain in the right hypochondrium (71.3%) and hepatomegaly (24.5%). In about 10% of cases, the cysts were discovered by chance. Ultrasound and CT scans facilitated diagnosis and determination of the position of the cysts, with reliability reaching 100% for CT scans. The cysts had burst in the bile ducts in 26.6% of cases and were infected in 8 cases. They were multivesicular in 77.5% of cases. Association with hydatidosis at another site was observed in 28 cases: in the peritoneum in 15, the thorax in 7, the diaphragm in 4, the spleen in 2 and the kidney in 1 case. Surgically, the route most frequently used was double incision below the rib cage (49.5%). It is not possible to recommend one particular way to treat cysts and the most appropriate approach to treatment depends on the site, type and number of cysts. Resection of the prominent dome is the technique most frequently used (57.25%). However, in recent years, the use of cystectomy has been increasing (20.2%) due to the considerable decreases in post-operative morbidity and duration of hospital stay that it affords. The principal post-operative complications observed were abscesses under the diaphragm (6 cases), biliary leakage (5 cases), pleurisy (6 cases) and the formation of abscesses in the vestigial cavity (4 cases). The rate of morbidity in the RDS appeared high, accounting for 75% of total morbidity. Only one patient died. This patient died from severe hepatic insufficiency due to the near destruction of the liver by the hydatosis. We observed two recurrences during follow up. Both underwent further surgery and neither suffered complications.

[Echinococcoses]. / Echinococcoses.

Human echinococcoses, cystic echinococcosis and alveolar echinococcosis are due to infections with the cestodes Echinococcus granulosus and E. multilocularis, respectively. Both zoonoses share a prolonged latency period before clinical presentation. However their evolution is fairly different: that of a begin tumor of the liver or lung for cystic echinoccocosis, and that of a slowly developing malignant tumor of the liver for alveolar echinoccocosis, with subsequent invasion of liver vessels and bile ducts and metastatic dissemination. Ultrasonography, CT-scan and specific serology are the key-exams for diagnosis. In both forms, surgery is the treatment of choice when a complete resection is possible. Liver transplantation may be an ultimate treatment option in very advanced cases of alveolar echinoccocosis. However, alternative treatment procedures have been proposed in the past 15 years and, combined with an earlier diagnosis, they have markedly improved patients survival and quality of life. Interventional radiology (puncture, aspiration, injection, reaspiration) has become a fully validated treatment of cystic echinoccocosis, and may be used in alveolar echinoccocosis for alleviating some of the complications of the disease such as biliary obstruction or bacterial superinfection. Albendazole, at high dosage, is a necessary complementary treatment after any intervention procedure, and for life when radical resection is not possible. Prevention relies on personal measures of hygiene and heating of contaminated food, and on collective measures aimed at reducing cestode egg shedding by the feces of infected canivores.

Fasciola hepatica as a cause of jaundice after chewing khat: a case report.

Fasciola hepatica is a worldwide distributed zoonotic trematode incidentally infecting humans. Although often symptomatic, fascioliasis can cause a wide spectrum of disease. The diagnosis can be established by stool examination detecting ova of the parasite, although serological testing has a higher sensitivity and specificity in the acute phase of disease. This case presents a 24-year-old Somalian man admitted with jaundice and abdominal discomfort due to fascioliasis after chewing khat. The patient was treated successfully with a single dose of triclabendazole.

A case of transplacental transmission of Theileria equi in a foal in Trinidad.

Equine piroplasmosis due to Theileria equi and Babesia caballi is endemic in Trinidad. A case of equine piroplasmosis due to T. equi was diagnosed in a thoroughbred foal at 10h post-partum. A high parasitaemia (63%) of piroplasms was observed in a Wright-Giemsa(®) stained thin blood smear from the foal. In addition, the 18S rRNA gene for Babesia/Theileria was amplified from DNA extracted from the blood of the foal and the mare. Amplified products were subjected to a reverse line blot hybridization assay (RLB), which confirmed the presence of T. equi DNA in the foal. The mare was negative by RLB but was positive for T. equi using a nested PCR and sequence analysis. In areas where equine piroplasmosis is endemic, severe jaundice in a post-partum foal may be easily misdiagnosed as neonatal isoerythrolysis. Foals with post-partum jaundice should be screened for equine piroplasmosis, which may be confirmed using molecular methods if available.
