Toxic hepatitis-associated aplastic anaemia after dual homeopathic remedies and Gymnema sylvestre use.

Hepatitis-associated aplastic anaemia (HAAA) is a rare condition characterised by onset of acute hepatitis which is followed by development of severe pancytopenia due to bone marrow failure within 6 months. This syndrome can be precipitated by acute viral infections, but the aetiology remains unknown in the majority. Drug-induced HAAA is extremely rare and has been reported with nutritional and dietary supplements in current literature. We report the first cases of ayurvedic herbal and homeopathic remedies-associated HAAA in two patients which proved fatal in both. Evaluation of patients with acute hepatitis and severe pancytopenia must include a detailed evaluation for complementary and alternative medicine use.

Treatment with Lycopodium clavatum 200dH Intensifies Kidney and Liver Injury in Mice Infected with Toxoplasma gondii.

The effects of infection with Toxoplasma gondii vary from asymptomatic to the development of alterations in various organs (including the liver and kidneys) which may be irreversible, and lead to the death of the host. Whereas homeopathy is an alternative and effective method for treating various diseases, including those caused by protozoa, we questioned the effect of using Lycopodium clavatum in mice infected with T. gondii. One hundred male Swiss mice, 60 days old, were divided into four groups (n = 25/group): NIC (uninfected and untreated control), IC (infected and treated with un-dynamized 7% alcohol solution [vehicle]), G48 (infected and treated 48 h before infection and treated three more times; at 2, 4, and 6 days post-infection (dpi) with L. clavatum 200dH), and G72 (infected and treated for 3 consecutive days before infection with L. clavatum 200dH). In this study, physiological, histopathological, and immunological parameters were evaluated. The L. clavatum 200dH intensified renal damage in mice infected with T. gondii from 7 dpi, causing severe and progressive alterations during this period, such as various degrees of inflammation, edema, atrophy, and tubular cystic dilation, degenerated tubules with intra-cytoplasmic vacuoles and coalescing spots, severe vascular lesions, glomerulonephritis, and peri-glomerular congestion. In the G72 animals, which received L. clavatum 200dH, more severe cortex damage was observed (91.66-96.66%) as compared to the IC group (55-80%) and more renal corpuscle, and renal tubule injury was observed (80 ± 5 to 96.7% ± 2.89 of the total area) during all periods, as compared to the IC group (p < 0.05). Both groups presented high liver enzyme levels, and the highest values for AST were observable at 60 dpi. We observed significant increases of type I and III collagen, as well as high levels of TGF-ß1 in both organs of the treated animals, the main factor involved in fibrosis in areas damaged by the process. L. clavatum 200dH intensifies kidney and liver alterations in mice infected with T. gondii. Our results reinforce caution when indicating administration schemes and dosages for ultra-diluted drugs.

Surveillance of suspected adverse reactions to natural health products in Italy.

PURPOSE: Natural health products are promoted to the public as equally or more effective and less toxic than conventional drugs. However, some 'natural' medicines, and in particular some herbal medicines, are known to have adverse effects. The Italian Pharmacovigilance System, in charge of the Italian Medicines Agency, collects spontaneous reports only for registered drugs. The awareness of the need of surveillance of the safety of natural health products has stimulated the implementation of a suspected adverse reaction reporting system in Italy. The system has been set up by the Italian National Institute of Health. METHODS: An ad hoc reporting form can be downloaded from different institutional web sites. Voluntary reports of suspected adverse reactions are sent to the National Institute of Health and are evaluated by a multidisciplinary group of experts. RESULTS: From April 2002 to March 2007, 233 spontaneous reports of suspected adverse reactions to natural health products were collected. A large proportion of suspected adverse reactions were serious: hospitalization was reported in 35% of forms; 6% reported life threatening clinical events and two fatal events were notified. About 50% of suspected adverse reactions were related to gastrointestinal, skin, psychiatric and nervous system disorders. Mainly herbal products (66%) were involved. Twenty-one cases of hepatitis of various seriousness were reported. Twenty-one reports were associated with 27 homeopathic preparations, mostly preparations containing mixtures of substances. Fourteen reports regarded suspected reactions to products containing propolis. CONCLUSION: Safety and efficacy of 'natural' medicines have not been thoroughly investigated. It is important to improve communication with the public on safety issues. Encouraging spontaneous reporting can contribute to improve awareness among health personnel and patients about the benefit-harm profile of these remedies.

[Characteristics of immune homeostasis in patients with cholelithiasis complicated by hepatitis and cholangitis].

The most distinctive and typical complications of cholelithiasis are cholangitis and hepatitis. The article presents an analysis of peculiarities of immune homeostasis in 41 patients with cholelithiasis complicated by hepatitis and cholangitis before and after surgical treatment and with the use of antihomotoxicologic and homeopathic medications.

Acute lead poisoning: an unusual cause of hepatitis.

Four patients, aged 17 to 25 years, obtained lead and opium pills which had been stolen from retail pharmacists. They crushed them, suspended them in water an injected them intravenously. They developed general malaise, vomiting and constipation, and blood tests several weeks after injection of the pills showed raised alkaline phosphatase and aspartate transaminases. All four patients had negative tests for the hepatitis B surface antigen. Liver biopsy specimens showed persistent hepatitis in one and resolving hepatitis in the remaining three. Liver lead levels were grossly elevated in every case. The liver lead levels found it the patients described here were up to 35 times greater than levels which have been reported in industrial lead poisoning. It is postulated that the livers of patients with chronic lead poisoning are able to withstand this insult whereas in the cases described the overwhelming dose of lead was sufficient to cause hepatic damage.

Hepatitis aguda recurrente inducida por albendazol / Recurrent albendazole-induced acute hepatitis

Resumen El albendazol es un medicamento usado para tratar infecciones por helmintos y usualmente presenta pocos o ningún efecto secundario. A pesar de que hay un incremento transitorio de enzimas hepáticas luego de su uso, existe poca evidencia en la literatura en la que se reporte lesión hepática luego de automedicación con albendazol. En este informe, el paciente se presentó con hepatitis aguda luego de automedicarse con albendazol. El paciente cuenta además con una historia de episodios similares después de haber usado el fármaco. Se evaluada la causalidad con el método de evaluación de causalidad de Roussel Uclaf del Concejo para Organizaciones Internacionales de Ciencias Médicas, cuyo resultado fue un puntaje de 10, lo que indicó una alta probabilidad de lesión hepática inducida por albendazol al cabo de realizarse una investigación rigurosa y de excluir otras posibles causas de la condición física del paciente. En conclusión, aunque es ideal agilizar el proceso para combatir a los helmintos, es necesario intensificar la necesidad de monitorizaciones de calidad para evitar reacciones adversas como la hepatitis inducida por medicamentos. Asimismo, la automedicación de cualquier medicamento debe ser siempre evitada.

Abstract Albendazole is used to treat helminth infections and usually has minimal or no side effects. A transient increase in liver enzymes is common following its use, but little evidence of albendazole-induced liver damage has been reported in the literature. This study presents a patient who developed acute hepatitis following self-medication with albendazole. The patient also had a history of similar episodes in the past after using the drug. After a thorough investigation and exclusion of all other causes of the patient's clinical condition, the Roussel Uclaf Causality Assessment Method of the Council for International Organizations of Medical Sciences scale yielded a score of 10 points, indicating a high probability of albendazole-induced liver damage. In conclusion, expediting the process of combating helminths is ideal, but quality monitoring is required to avoid adverse reactions such as drug-induced hepatitis. Moreover, self-medication with any drug should always be discouraged.

Hepatotoxicidade induzida por sulfassalazina: relato de caso / Hepatotoxicity induced by sulfasalazine: case report

A sulfassalazina é ainda muito utilizada nas doenças inflamatórias intestinais, sobretudo na retocolite ulcerativa leve e moderada. Entretanto, seu uso é relacionado a vários efeitos colaterais, incluindo disfunção hepática grave.Este é um relato do caso de paciente masculino, 21 anos, portador de retocolite ulcerativa moderada, com queixa de inapetência, febre, artralgia e icterícia, há sete dias. Antecedente pessoal de uso de sulfassalazina 4 g/dia há seis semanas. Ao exame físico apresentava-se ictérico, com exantema em membros e edema de membros inferiores. Exames complementares mostravam aumento de bilirrubinas, enzimas hepáticas e canaliculares e da proteína C reativa. Com o diagnóstico de hepatotoxicidade por sulfassalazina, foi suspensa a medicação e introduzido prednisona 20 mg/dia e ciprofloxacino 1 g/dia. Recebeu alta no terceiro dia de internação após melhora clínica e laboratorial. Atualmente encontra-se assintomático e em uso de azatioprina 150 mg/dia.

The sulfasalazine is widely used in inflammatory bowel disease, especially in mild and moderate ulcerative rectocolitis. However, its use is related to several side effects, including severe liver dysfunction.
