A perinatal cytomegalovirus infection in an immunocompetent patient with chorioretinitis.

Cytomegalovirus (CMV) infection is the most common viral infection of newborns in all periods worldwide. Perinatal form of infection is usually less severe than the congenital form because of having a lower rate for serious organ involvement like central nervous system. In this article, we report a 3-month-old immunocompetent patient who was diagnosed as having perinatal CMV infection with a scar of chorioretinitis after presenting with gastroenteritis and hepatitis.

[Granulomatous pneumonia as a complication of intravesical BCG immunotherapy--a case report]. / Zapalenie ziarniniakowe pluc jako powiklanie leczenia dopecherzowymi wlewkami BCG--opis przypadku.

BCG (Bacillus Calmette-Guerin) comprises an attenuated strain of Mycobacterium bovis and is used for vaccination against tuberculosis. An additional use of BCG is for immunotherapy of cancer in which the vaccine is administered intravesically for the treatment of superficial bladder cancer. The efficacy of immunotherapy with BCG in the prevention of recurrence is estimated at 70-99%, which is higher than for local chemotherapy. The most frequent complications of such treatment include fever and urinary bladder inflammation, while serious complications of haematogenous organ inflammation, especially inflammation of the lungs with the formation of pulmonary caseosus granulomas, are rarely seen. The authors reported a case of a 68-year-old man who was treated with intravesical BCG instillations due to a superficial bladder cancer. The patient underwent transurethral resection of bladder cancer and then periodically received intravesical BCG instillations. A few days after one instillation, systemic symptoms with a high fever appeared. Further examinations showed features of hepatitis and spread pulmonary changes. The patient underwent videothoracoscopy, and a fragment of lung parenchyma was collected. The histopathological examination revealed the presence of granulomas with central caseosus necrosis. Suspecting BCG infection, diagnostics were enhanced to include bacteriological and genetic tests for the presence of acid-resistant bacilli, which finally gave negative results. The authors diagnosed granulomatous pneumonia as a complication of intravesical BCG immunotherapy. Treatment with antituberculous drugs was initiated. After completing pharmacological treatment, radiological control was performed, which showed significant but not complete remission of pulmonary changes.

Extracorporeal artificial liver support in hypoxic liver injury.

The incidence of hypoxic liver injury, most commonly referred to as hypoxic hepatitis (HH), is up to 10% in critically ill patients. In the majority of cases, HH occurs as a consequence of haemodynamic impairment following cardiogenic or septic shock. A marked, dramatic increase in the aminotransferase levels in a setting of cardiocirculatory failure is the key characteristic of HH. HH may contribute to several complications such as hepatopulmonary syndrome and hypoglycaemia. The overall mortality after the onset of HH is approximately 50-60% within 1 month. We report a case of severe HH that was successfully bridged using the Molecular Adsorbent Recirculating System. In addition to the possible effects of extracorporeal liver support devices, the recognition of HH and therapy of the underlying disease that led to the occurrence of HH is of central importance.

Novel Strategies to Prevent Total Parenteral Nutrition-Induced Gut and Liver Inflammation, and Adverse Metabolic Outcomes.

Total parenteral nutrition (TPN) is a life-saving therapy administered to millions of patients. However, it is associated with significant adverse effects, namely liver injury, risk of infections, and metabolic derangements. In this review, the underlying causes of TPN-associated adverse effects, specifically gut atrophy, dysbiosis of the intestinal microbiome, leakage of the epithelial barrier with bacterial invasion, and inflammation are first described. The role of the bile acid receptors farnesoid X receptor and Takeda G protein-coupled receptor, of pleiotropic hormones, and growth factors is highlighted, and the mechanisms of insulin resistance, namely the lack of insulinotropic and insulinomimetic signaling of gut-originating incretins as well as the potentially toxicity of phytosterols and pro-inflammatory fatty acids mainly released from soybean oil-based lipid emulsions, are discussed. Finally, novel approaches in the design of next generation lipid delivery systems are proposed. Propositions include modifying the physicochemical properties of lipid emulsions, the use of lipid emulsions generated from sustainable oils with favorable ratios of anti-inflammatory n-3 to pro-inflammatory n-6 fatty acids, beneficial adjuncts to TPN, and concomitant pharmacotherapies to mitigate TPN-associated adverse effects.

Peritoneal tuberculosis and granulomatous hepatitis secondary to treatment of bladder cancer with Bacillus Calmette-Guérin.

Intravesical administration of Bacillus Calmette-Guérin is used as a treatment method in superficial bladder cancer. While it is generally well tolerated, serious side effects may develop. Granulomatous hepatitis cases have been previously reported; however, only one case with tuberculous peritonitis exists in the current literature. We hereby present two cases, one of which is the second tubercular peritonitis case following Bacillus Calmette-Guérin treatment to be reported, and the other a case with granulomatous hepatitis. Complete cure was achieved in both cases with specific therapy. In the patient who developed peritonitis, intravesical Bacillus Calmette-Guérin therapy was recommenced after antituberculosis treatment, and completed without further complications.

Hepatic Injury without Granulomatous Formation Associated with Intravesical Bacillus Calmette-Guérin Therapy.

A 74-year-old man developed hepatic injury after intravesical Bacillus Calmette-Guérin (BCG) therapy for bladder carcinoma. Although hepatitis-associated disseminated BCG was suspected, granulomatous formations were undetectable. The hepatic injury was considered to have resulted from an allergic reaction to BCG therapy because a histopathological assessment revealed enlarged portal areas with eosinophils and neutrophils. The hepatic injury was resolved by prednisolone. This case suggested that hepatic injury associated with BCG therapy might be due to an allergic mechanism unrelated to disseminated BCG disease. A liver biopsy is needed to confirm the histopathological findings of hepatic injury after BCG therapy in order to differentiate allergic hepatic injury from infectious hepatic injury.

Literature review of liver injury induced by Tinospora crispa associated with two cases of acute fulminant hepatitis.

INTRODUCTION: Species of Tinospora are used as herbal remedies for the treatment of various diseases with very few toxic effects having been reported. Tinospora cordifolia (TCF) has been reported to effectively prevent hepatotoxicity. However, there are an increasing number of cases revealing that Tinospora crispa (TCP) might have the negative effect of inducing hepatotoxicity. Because of the similar leaves, people may mistake TCP for TCF, and consume it with the purpose of protecting liver function. OBJECTIVE: Find out the misusing level of TCP and TCF and which chemical compound in TCP might induce hepatotoxicity. METHODS: We report two cases of acute fulminant hepatitis associated with chronic use of TCP. Given that the two herbs were misidentified in these two reports, we investigated the frequency of erroneous identification by using three keywords ("Guduchi", "Tinospora cordifolia", "Tinospora crispa") to search images from the Google Images database. To further clarify the influence of liver function between TCP and TCF, we searched PubMed (up to 29 July 2018) for relevant publications on clinical trials or case reports. RESULTS: Based on web review, over 35 percent of websites failed to accurately identify these two herbs. The different effects on liver function between TCP and TCF were compared through literature review. It indicated that TCF exerted liver protection, TCP had a contrary effect, suggesting its cis-Clerodane-type furano-diterpenoids might be an important factor of inducing hepatotoxicity. CONCLUSIONS: We concluded that people might cause hepatic injury or even death without correctly identifying these two Tinospora species.

Hypoxic hepatitis and furosemide.

Hypoxic hepatitis is a rather common complication of heart, circulatory or respiratory failure. We present the case of a patient with hypoxic hepatitis in the setting of heart failure and dehydration from furosemide as a reminder of an important clinical lesson. The pathogenesis of hypoxia (especially in the case of heart failure) is explained by a two-hit mechanism in which the liver at risk of hypoxic injury by passive hepatic congestion (right heart failure) is subsequently exposed to systemic hypoperfusion, which leads to a marked and transient elevation of aminotransferases. In the case presented, the use of furosemide (at least partially) promoted the second hit because it helped to generate hypotension and splanchnic hypovolaemia and favoured hepatic hypoxia.

Dabigatran overdose: a case report of acute hepatitis. Extracorporeal treatment.

Dabigatran is an oral, direct thrombin inhibitor approved by international regulatory agencies for stroke prevention in patients with paroxysmal or persistent non-rheumatic atrial fibrillation (AF). The benefits of dabigatran are widely described, but its use in the geriatric population is not without risk. Chronic kidney disease is a common comorbidity with AF, and thus frequent checks of renal function in elderly patients are recommended. We report a case of dabigatran intoxication in an elderly man affected by heart failure and worsening renal function, who developed acute hepatitis and coma, which was successfully treated with continuous veno-venous hemodiafiltration. Although extracorporeal therapy has been suggested as a strategy for clearing dabigatran during acute bleeding, this approach may be useful in other dabigatran-related, life-threatening conditions, such as that described in this report.

Severe Systemic Lead Toxicity Resulting From Extra-Articular Retained Shrapnel Presenting as Jaundice and Hepatitis: A Case Report and Review of the Literature.

INTRODUCTION: Despite greater than 60,000 nonfatal firearm injuries per year in the United States, retained shrapnel is a relatively rare cause of systemic lead toxicity with less than 100 cases reported in the medical literature since 1867. While intra-articular retained shrapnel as a cause of lead toxicity is well-described, extra-articular fragments are less well known to cause symptomatic disease. CASE REPORT: A 31-year-old man initially presented with abdominal pain, constipation, jaundice, and elevated liver transaminases approximately 3 weeks after suffering a left lower extremity injury during athletic activity. The patient was found to have steatohepatitis after extensive inpatient and outpatient gastroenterological workup to include upper and lower endoscopy, liver ultrasound, and biopsy of the liver to confirm the diagnosis. Imaging was incidentally notable for retained gunshot in the left flank and large shell fragment containing seroma in the left thigh. The patient was initially discharged with improved pain, but later presented to a primary care clinic with weight loss and continued pain. This was followed by a subsequent progression to diffuse weakness, ultimately resulting in an inability to ambulate. The patient was readmitted to a tertiary care medical center, 3 months after the initial presentation. Physical exam was then notable for 70-lb weight loss from initial admission and diffuse peripheral weakness with global muscle atrophy. Following a broad differential workup, he was found to have a blood lead level of 129 µg/dL, and hemoglobin of 7.7 g/dL with basophilic stippling on peripheral smear. The patient was transferred to the intensive care unit for chelation therapy with dimercaprol and calcium ethylenediaminetetraacetic acid. Lead levels initially decreased, but rose when patient was transitioned to oral therapy with succimer. Surgery was consulted for removal of multiple retained fragments, which were analyzed by the Joint Pathology Center and found to contain lead. The patient's motor function gradually improved on oral chelation and he was discharged to a subacute rehabilitation facility. CONCLUSION: This complex case describes a rare cause for a relatively common clinical presentation, jaundice and hepatitis, and reinforces the importance of longitudinal follow up and reassessment of a patient with an unknown illness and worsening clinical condition. Diagnosis of systemic lead toxicity is challenging because of its protean clinical manifestations, and relative rarity with the advent of strict environmental lead controls and decrease in lead-based paint and industrial products. Furthermore, extra-articular lead remains a rare cause of systemic toxicity, and the surgical standard of care has been to not remove these fragments in gunshot victims. This case adds to a small amount of evidence that lead screening may be of value in selected patients with extra-articular retained shrapnel, especially those with seroma and osteophyte formation in the wound.

Granulomatous hepatitis in a patient with Crohn's disease and cholestasis.

We describe a case of a 23-year-old woman with a history of Crohn's disease (CD), who initially presented with sepsis-like symptoms, subsequently developed severe cholestasis and following extensive inpatient workup was found to have non-caseating granulomas on her liver biopsy. Infectious aetiologies were excluded and the patient was treated with oral corticosteroids, which ameliorated but did not completely reverse the cholestasis. We review the differential diagnosis of hepatic granulomas and discuss the potential difficulties in establishing their exact aetiology in patients with CD.

[Granulomatous hepatitis successfully treated with ursodeoxycholic acid]. / Ursodeoxycholsavval sikeresen kezelt granulomás hepatitis.

The etiology of granulomatous hepatitis is extremely extensive for which the granulomatous reaction induced hepatic inflammation is characteristic. In the majority of cases it is part of a systemic disease but sometimes there is primer hepatic lesion in the background. The 21 year-old Caucasian female patient was taken to hospital having flu-like symptoms and icterus. While searching for the cause of her cholestatic hepatocellular lesion infections, tumors, storage diseases were excluded. However the root cause could not be identified. The histology showed granulomatous reaction, inflammation, intrahepatic bile duct proliferation and micronodular cirrhosis in the liver tissue. Taken it into consideration together with the the clinical picture and the laboratory findings primer sclerosing cholangitis was rendered probable. Her state deteriorated and even the necessity of liver transplantation emerged. The patient was treated with ursodeoxycholic acid which resulted in remission lasting for years now. Two years after the onset of the hepatic disease pancolitis ulcerosa with affection of the ileum terminalis was found in the patient which supports the diagnosis of primary sclerosing cholangitis.

Autoimmune Colitis and Subsequent CMV-induced Hepatitis After Treatment With Ipilimumab.

Ipilimumab, a humanized CTLA-4 antibody, improves overall survival in patients with metastatic melanoma. However, immune-related adverse effects occur in about 65% of ipilimumab-treated patients and have to be adequately managed. A 55-year-old patient developed grade 3 autoimmune colitis 7 weeks after initiation of ipilimumab treatment and subsequently hepatitis with grade 3 elevation of transaminases and γ-glutamyl transferase. Colitis manifested with up to 18 watery and bloody stools per day and severe attacks of abdominal pain. After exclusion of infectious causes, immunosuppression with corticosteroids was initiated. Because of recurrent abdominal pain, spontaneous perforation of the colon had to be excluded. Elevated liver function tests (grade 3 CTCAE) occurred and differential diagnosis included immune-mediated, toxic, and viral hepatitis. It is interesting to note that, not an immune-mediated but a cytomegalovirus-induced hepatitis was diagnosed by serum blood tests and liver biopsy and was subsequently successfully treated. Careful elaboration of the patient under immunotherapy was essential as further immunosuppression mandatory for autoimmune hepatitis would have worsened the viral hepatitis. In conclusion, cytomegalovirus reactivation should be included in the differential in patients under immunotherapy with checkpoint inhibitors and has to be considered as a cause for morbidity.

Secondary syphilitic hepatitis in a fourteen-year-old male youth.

An unusual case of a secondary syphilitic hepatitis in a 14-year-old male youth is presented. Although he had extremely high aspartate and alanine aminotransferase values, improvement was rapid after antibiotic therapy. Histologic examination of the liver performed during convalescence revealed patchy necrosis and inflammatory cell infiltration.

Prevention of sexually transmitted diseases in women.

The frequency and severity of sexually transmitted diseases (STDs) and their sequelae, including sterility, numerous perinatal infections, genital tract neoplasia and possibly death (from ectopic pregnancy, ruptured tuboovarian abscess, human immunodeficiency virus-1 and hepatitis B virus infection), should be acknowledged by all sexually active individuals. Aspects of sexuality that place individuals at risk of STDs must be reexamined. Health care providers must effectively inform patients and the public of these often-ill-appreciated risks in a straightforward fashion, free of judgmental and punitive attitudes. New, more-effective means of prevention, diagnosis and treatment are being sought using research techniques in microbiology, immunology and behavioral science. In the meantime, medical screening, treatment and contact tracing should be carried out for patients and their sexual partners. Sexually active individuals must be empowered with knowledge and emboldened to protect themselves and their established or potential families from these common infections. Existing means of screening and treating must be utilized fully.

Local anaesthetic adverse effects and other emergency problems in general dental practice.

This paper has three parts: local anaesthetic adverse effects, haemorrhage control and altered immune response. Primary emphasis is placed on the problems with anaesthetics since their use is widespread. Every day, nearly 2 million injections of local anaesthetic are given in dental practice. From 2.5 to 10 per cent of patients experience adverse reactions. This adverse effect rate is 10 times higher than that in medicine for the same drugs. Allergic, toxic, idiosyncratic and psychogenic effects are discussed. New data on the role of local anaesthetic agents, vasoconstrictors and preservatives is presented. In addition, the problem of anaesthetic failure (occurring in over 10 per cent of patients) is explained. Treatment (drug and psychological) for anaesthetic related emergencies such as panic attacks, shortness of breath, palpitations and nausea is recommended. Prevention and treatment of haemorrhage is explained. Medical and dental conditions may increase clotting time (e.g., systemic disease or local factors such as granulation tissue). Preventive strategies are outlined and laboratory tests discussed. Emphasis should be placed on the use of local anaesthetics with vasoconstrictors, haemostatic agents and pressure. The final aspect of the paper discussed new data on problems for dentists arising with patients who have altered immune function. In particular AIDS is discussed from the point of view of protection of the dentist and dental treatment for the patient.
