Onychomycosis in inflammatory bowel diseases.

BACKGROUND: As far as we have sought for in Medline and PubMed, not one study until now has evaluated the prevalence of onychomycosis in patients with inflammatory bowel disease (IBD). As there are great evidence of immunological disturbances linked to IBD, a possible relationship of this nail infection in association with those diseases and the possible risk factors might be relevant in IBD patients. METHODS: A case-control prospective study using combined direct smear and cultures for fungus was performed. Sociodemographics, clinical and laboratorial data were recorded at baseline and samples of suspected nails were collected from 141 IBD (61 men and 80 women) and from a group of 100 non-IBD subjects (41 men and 59 women). Direct smear and cultures were performed on each suspected case to exclude other onychodystrophies. RESULTS: The incidence of onychomycosis in IBD patients was highly significant in comparison to non-IBD patients (14.9% vs. 6%, respectively, P < 0.05). The risk factors predisposing IBD patients to onychomycosis were older age (P = 0.02) and leucopoenia in those using azathioprine therapy (P = 0.04) beyond a trend to lymphopenia (P = 0.06). The dermatophytes predominated (76.2%) over yeasts (19%) and moulds (4.8%). CONCLUSION: The prevalence of onychomycosis in IBD patients was expressively high (14.9%) in comparison with non-IBD patients. Considering the sociodemographic factors, any one but two were related to fungal onychomycosis incidence. Therefore, as far as we are concerned, IBD must be included in the high-risk underlying conditions for onychomycosis occurrence.

Colonic ulcers in propylthiouracil induced vasculitis with secondary antiphospholipid syndrome.

A 48 year old white woman was admitted to the hospital because of several bouts of migratory polyarthritis, weight loss, fever, and abdominal pain over a period of 15 months. She had been taking propylthiouracil 100 mg daily for three years for hyperthyroidism treatment. A test for antineutrophil cytoplasmic autoantibodies (ANCA) was positive with a perinuclear pattern of staining. Antiphospholipid antibodies were also detected. Colonoscopy showed several ulcers on intestinal mucosa and the biopsy specimen showed intense microscopic vasculitis. The patient is well after methylprednisolone pulse therapy and eight months of oral azathioprine. A surveillance colonoscopy showed complete healing of intestinal ulcers. No recurrence of symptoms has occurred and autoantibodies are negative, 10 months after treatment finished. The sequence of events suggests a propylthiouracil induced vasculitis p-ANCA positive and an antiphospholipid syndrome. This is the first report of colonic ulcers diagnosed and successfully treated in such circumstances.

Fatal evolution of systemic lupus erythematosus associated with Crohn's disease.

The authors describe the case of a young Brazilian woman who was treated of ileocolonic Crohn's disease sparing rectum, as confirmed by colonoscopy and histopathological examination. After a 4-year course of sulfasalazine treatment, she presented with skin facial lesions in vespertilio, fever, arthralgias and high titers of anti-ANA and LE cells. A sulfasalazine-induced lupus syndrome was diagnosed, because after sulfasalazine withdrawal and a short course of prednisone, the clinical symptoms disappeared and the laboratory tests returned to normal. Mesalazine 3 g/day was started and the patient remained well for the next 3 years, when she was again admitted with fever, weakness, arthralgias, diplopy, strabismus and hypoaesthesia in both hands and feet, microhematuria, haematic casts, hypocomplementemia and high titers of autoimmune antibodies. A diagnosis of associated systemic lupus erythematosus was made. Although a pulsotherapy with methylprednisolone was started, no improvement was noticed. A cyclophosphamide trial was tried and again no positive results occurred. The patient evolved to severe clinical manifestations of general vasculitis affecting the central and peripheral nervous system and lungs, having a fatal evolution after 2 weeks. Although uncommon, the association of both disease may occur, and the authors call attention to this possibility, making a brief review of literature.

[Hyperlipemic pancreatitis: clinical course]. / Pancreatite hiperlipêmica: aspectos clínico-evolutivos.

Acute pancreatitis is one of the complications associated with severe primary and secondary hypertriglyceridemia. The frequency of hypertriglyceridemia in patients with pancreatitis ranges from 4 to 53%. The elevation in serum triglycerides probably induces the release of free fatty acids, responsible for the pancreatic damage. During a three year study, nine patients with acute pancreatitis due to hypertriglyceridemia were followed up at the University Hospital of Federal University and at the "Hospital Monte Sinai" (Juiz de Fora, MG, Brazil). Suggestive clinical manifestations, especially superior abdominal pain, nausea, vomiting and ileus, were found in all the patients; however, only three showed elevated serum amylase levels. All had triglyceride levels above 1000 mg/dl (11.3 mmol/L). The evolution after clinical treatment was good in eight patients (two needed parenteral nutrition). The only death observed was due to shock and acute respiratory distress, refractory to clinical management. The maintenance treatment aimed at withdrawing the predisposing conditions and reduction of the triglyceride levels prevented recurrence of acute pancreatitis episodes during the 23 months of follow-up.

[Epidemiology, clinical features and clinical course of Crohn's disease: a study of 60 cases]. / Epidemiologia, aspectos clínicos e evolutivos da doença de Crohn: um estudo de 60 casos.

The authors present their experience with the follow-up of 60 cases of Crohn's disease, from 1970 until 1998, in the city of Juiz de Fora, Minas Gerais state, a county of the Southeast region of Brazil, and analyse the epidemiology of disease to improve the understanding of its behaviour in the country. The incidence rates increased greatly in the last 28 years. In the group studied 53.3% were men, 90% white, 71.7% non-smokers, 93.3% non-alcoholics, and all, but two, lived in urban area; 58.3% had their symptoms started at the age between 11 and 30 years and 30% were in the second decade of life. Relatives with Crohn's disease were seen in 6.7%, and the most common symptoms observed at the beginning of disease were: abdominal pain (78.3%), diarrhea (68.3%), weight loss (26.7%) and small bowel obstruction or localized peritonitis (15%). The ileum was involved in 90% and five cases (8.3%) with lesions restricted to the colon were observed. Two patients died because they were non-responders despite any therapy schedule and had sepsis after surgery. The effect of several substances used in the treatment is described, being prednisone the most effective in controlling the active disease. Other drugs as aminosalicilates, metronidazol and immunomodulators are also considered to avoid the side-effects of long-term use of steroides. Comments are made about the clinical evolution, surgeries and response to many treatments adopted. The authors conclude that Crohn's disease is increasing its incidence rate in Brazil and probably in South America formerly considered as a region of low frequency.

[Intestinal parasitosis and hepatic cirrhosis]. / Parasitoses intestinais e cirrose hepática.

The authors describe their experience, in a prospective survey, with the prevalence rates of intestinal parasites in patients with hepatic cirrhosis admitted to the Gastroenterology Unit of University Hospital of Federal University in Juiz de Fora, Brazil, whose fresh stools were examined by Hoffman-Pons-Janner, Baermann-Moraes and Willis methods. They compare the results of stool exams with two control groups and look for a relation with cirrhosis' etiology. A higher prevalence of some parasites was observed in cirrhosis than in people with other digestive diseases (group I). mainly for the Strongyloides stercoralis, found in 40.2%, chiefly in alcoholic cirrhosis. Oddly no one of the group I admitted in the same period had strongyloidiasis. Another group including all the people who had stool samples examined in the same period at the hospital had 1.91% of that helmintic infection (group II). A comparison is also made with the prevalence in schoolchildren between the ages of 7 and 14 studies eight years before (13.16%). Other parasites were also observed in different incidence between those with cirrhosis and the other groups and the results are presented. They conclude that hepatic cirrhosis must be included in the list of conditions which increases the risk of Strongyloides stercoralis infection.

PIP: In a prospective study conducted between July 1995 and June 1996 the prevalence of intestinal parasites is described in 35 (32 male, 3 female) patients with hepatic cirrhosis, aged 13-77 years, who had been admitted to the gastroenterology unit of the Federal University in Juiz de Fora, Brazil. The causes of cirrhosis were: alcohol (19 cases), hepatitis B virus (HBV) (3 cases), hepatitis C virus (HCV) (5 cases), HBV and HCV (2 cases), cryptogenetics (3 cases), Wilson's disease (1 case), biliary cirrhosis (1 case), and Gaucher's disease (1 case). Another 45 patients who were hospitalized during this period served as controls (Group I). Group II was comprised of 1411 persons who underwent parasitological tests during December 1995 and May 1996. Comparison was also made with 7371 tests performed in children aged 7-14 years who had been studied in 1988. Stools were examined by the Hoffman-Pons-Janner, Baermann-Moraes, and Willis methods. The results of stool exams were compared with those of the two control groups. A higher prevalence of some parasites was observed in cirrhosis patients than in patients with other digestive diseases (Group I). Of the 35 cirrhosis patients, 19 presented with positive parasite tests. Strongyloides stercoralis was found in 40.2%, chiefly in alcoholic cirrhosis patients, which was significant when compared to the other two control groups, but not significant when compared to the patients with nonalcoholic cirrhosis (4 cases of strongyloidiasis out of 16 patients). None of the 45 patients in Group I had strongyloidiasis. Group II (including all the people who had stool samples examined during the same period in the hospital) had a 1.91% rate of helminthic infection. A rate of 13.16% was found in the children's group.

[Hepatic puncture biopsy in the outpatient clinic]. / Biopsia hepática por puncão em ambulatório.

The authors present the results of a prospective study on percutaneous needle biopsy of the liver conducted at the Hepatology Outpatients' Ward of the Gastroenterology Unit of the University Hospital -" Universidade Federal de Juiz de Fora", MG, Brazil. In 16 months 61 biopsies were made in patients with chronic liver disease according to the technique described by menghini. The inclusion criteria were established by The Patient Care Committee of The American Gastroenterological Association. Abdominal ultrasound was done before and after the procedure. The patients stayed six hours under control (blood pressure and pulse rate) in the hospital. After 24 hours other clinical, laboratorial and ultrasonic control were performed. The main complication was local pain or in the right shoulder (32 patients--52.5%). Abdominal ultrasound after 24 hours revealed only one hematoma of the abdominal wall (1.8%). This study shows that the outpatient needle liver biopsy is a safe procedure with low complication rate when performed in a judicious way, by specialized personnel and under strict clinical control.
