Clinical and epidemiologic examinations of 260 workers engaged in enzyme production revealed the structure of skin disease incidence: mycoses--31%, atopic dermatitis--19%, contact dermatitis--9%, allergic, dermatitis--5%. The majority of these skin diseases were associated with hyperphosphatemia and monoaminoxidase (MAO) depression. Changes of alkaline phosphatase and MAO activities, serum albumins and gamma-globulins may be considered as sensitive markers of disease.

Enzymes liberated by growing dermatophytes are of pathogenetic importance in tinea. To investigate the influence of nutrients on this enzyme release, Trichophyton rubrum was grown in media containing peptone, keratin and lipids, to which glucose was added in separate assays. The culture supernatants were compared for extracellular enzyme activities by use of the api-zym-test. Our results clearly show that the extracellular enzyme activity is dependent on the nutrients supplied. Seven different enzymes were released when keratin was supplied, as compared to only 5 and 2, respectively, when lipids or peptone were available. Among these enzymes alkaline phosphatase and N-acetyl-beta-glucosaminidase were detected in all cultures lacking glucose. Enzyme release was inhibited completely when glucose was added to the media, except for N-acetyl-beta-glucosaminidase in peptone cultures. This dependency of enzyme release on fungal nutrition can be expected to occur in vivo, too. In addition, it has to be considered for in vitro cultural conditions. Alkaline phosphatase and acetyl-glucosaminidase may be more important in tinea than has been assumed so far.

Griseofulvin(GF) has become the drug of choice as an antifungal agent for patients who suffer from many kinds of fungal infection. In order to clarify hepatic injury by griseofulvin(GF) overload and the effect of UDCA on GF-induced hepatic injury, the authors carried out biochemical, histologic, and ultrastructural studies of liver following treatment with griseofulvin and ursodeoxycholic acid(UDCA) in mice. Urine porphobilinogen excretion in the group treated with GF alone was significantly increased and reached the highest level in the 4th week and declined thereafter. Biochemical studies of the liver function showed no remarkable changes of serum bilirubin levels throughout the experimental period in all groups, except for SGPT and alkaline phosphatase activities which were significantly elevated and reached the highest level in the second week. Then they slightly decreased in GF treated groups(GF alone and GF plus UDCA) in comparison with the control group. Pathologic findings in the group treated with GF alone include focal liver cell necrosis(esp, zone 3), Mallory bodies in hepatocytes(esp, zone 1), Kupffer cell activation, and brown protoporphyrin pigments in the hepatocytes, bile canaliculi and interlobular bile ducts with a marked inflammatory cell infiltration in the portal tracts. Under the polarizing light microscope, bile ductular and canalicular thrombi showed a "Maltese cross" birefringence in mice treated with GF alone. There is no definite finding of fatty change in hepatocyte. Under the microscope, the liver appeared normal with an intact lobular architecture in the GF plus UDCA treated group. Electron microscopically, GF-induced changes include swelling of mitochondria, globular protoporphyrin crystals in the hepatocyte cytoplasm, markedly dilated bile cannaliculi and bile ducts and the formation of a Mallory hyaline bodies in the hepatocytes. There were no noticeable structural changes in the GF plus UDCA-treated group. Therefore the results suggest that GF causes hepatic injury, namely porphyria and cholestasis, and the treatment of UDCA may have cytoprotective and choleretic effects on GF-induced hepatic injuries.

Three children with acute lymphoblastic leukemia developed disseminated fungal disease predominantly involving the liver and spleen. The three patients were undergoing induction chemotherapy and had neutropenia when they presented prolonged fever not responsive to antibiotics. Once neutropenia was recovered, hepatosplenomegaly leukocytosis, elevated serum alkaline phosphatase, and hypoechoic areas in the spleen and liver ultrasound were observed. All fungal blood cultures were negative, with the diagnosis being confirmed by histologic study. One of the patients died without achieving control of the candidiasis. The other two patients received prolonged antifungal treatment concurrently with chemotherapy and both are alive, one of them cured and in complete remission. The increasing frequency of this infection in recent years and the importance of a prompt and prolonged administration of antifungal therapy to obtain the cure are discussed.

The influence of immunosuppression by T-2 mycotoxin on the fungal disease aspergillosis was investigated in rabbits. Four groups of rabbits (groups 1A, 1B, 3A, and 3B) were given 0.5 mg of T-2 toxin/kg of body weight/day, PO; in addition, rabbits of groups 3A and 3B were exposed to aerosols of Aspergillus fumigatus conidia from days 7 through 16. Rabbits of groups 2A and 2B were exposed to A fumigatus aerosols, but were not given T-2 toxin, and rabbits of group 0 served as controls. Two rabbits of group 1A, 1 rabbit of group 1B, and 1 rabbit of group 3A died before scheduled necropsy. Rabbits of groups 1A, 2A, and 3A were killed and necropsied on day 17, and the remaining rabbits (groups 0, 1B, 2B, and 3B) were killed and necropsied on day 28. Changes caused by T-2 toxin included leukopenia, marginal anemia, and increased number of and morphologic changes in nucleated erythrocytes by day 21, followed by a regenerative hematologic response. Serum alkaline phosphatase and sorbitol dehydrogenase activities and antibody response to A fumigatus (as measured by an indirect hemagglutination test) were decreased by T-2 toxin ingestion. Rabbits with aspergillosis had leukocytosis, increased PCV, and increased antibody response to A fumigatus. Histologic lesions consisting of centrilobular hepatocellular swelling, portal and periportal fibrosis, and lymphocyte necrosis and/or depletion within secondary lymphoid tissue were observed in most rabbits treated with T-2 toxin. Normal defense mechanisms against A fumigatus infection were compromised by T-2 treatment, as evidenced by the severity and extent of lung lesions, greater number of hyphal elements observed, and greater number of colonies of A fumigatus isolated from rabbits of groups 3A and 3B. There were no significant changes in group-0 rabbits.

The coexistence of a T-cell lymphoma with a myelodysplatic syndrome seems to be exceptional. In the case reported here the diagnostic problems raised by the appearance of cutaneous nodules in a patient with chronic myeloid leukaemia (CML) were solved by histo-immunological examinations. A 70-year old male patient had been presenting since 1976 with a psoriasis-like skin disease. He was first seen at the Argenteuil hospital in 1984. Physical examination showed psoriasiform finger-like erythemato-squamous lesions, infiltrated plaques and an ulcerated tumoral swelling of the right elbow. A diagnosis of mycosis fungoides was made on histological and immunological examination results. At histology, this epidermotropic lymphoma was peculiar in that the atypical infiltrate was clearly centred on vessels. Electron microscopy confirmed that the vascular walls were invaded by the mycosis cells. Additional examinations showed hyperleucocytosis and myelaemia which were rapidly attributed to a chronic myelocytic leukaemia since the Philadelphia chromosome was present and the leucocytes had a low alkaline phosphatase score. Bone marrow biopsy disclosed a myeloproliferative syndrome of the CML type. Biopsy of a right axillary lymph node showed myelocytic infiltration associated with dermopathic lymphadenitis. There were no circulating Sezary cells, and a search for extension proved negative. From May, 1984 to June, 1985 the patient's CML was treated with busulfan which produced blood and bone marrow remission. The skin lesions were treated first with mechlorethamine, then with topical corticosteroids. Superficial electron therapy was applied to the tumoral lesions.(ABSTRACT TRUNCATED AT 250 WORDS)

Forty-three patients, most with solid tumours, were included in a study comparing the antifungal prophylactic effect of ketoconazole (Nizoral; Janssen) 200 mg/d and 400 mg/d during the period of immunosuppressive therapy. Seven patients were not seen for follow-up and 6 died of their underlying disease without clinical evidence of mycosis. Twelve of the patients who could be evaluated received ketoconazole 200 mg/d and 18 received 400 mg/d. No infections occurred during the period of prophylactic treatment. In the group receiving 200 mg/d 10 of 36 cultures (28%) were positive for Candida albicans before prophylaxis. During prophylaxis 5 of 18 cultures (28%) were positive and at the end of the prophylactic regimen 1 out of 37 cultures (3%) was positive. In the 400 mg/d group, 13 of 47 cultures (28%) were positive at the start, 2 out of 20 (10%) were positive during prophylaxis and 1 out of 45 (2%) was still positive at the end. The drug was clinically well tolerated. Twenty of the 30 evaluable patients had no significant biochemical abnormalities, 5 had an increased serum transaminase level, 2 had an increased alkaline phosphatase level, and 3 had combined increases of serum transaminase and alkaline phosphatase levels. These abnormalities are regularly seen in patients with metastatic malignant disease, and are not necessarily related to the ketoconazole prophylaxis.

Silent and symptomatic hepatic reactions have occurred during ketoconazole treatment. The silent reactions (transient asymptomatic elevations of serum transaminase or alkaline phosphatase levels) may occur at any time during ketoconazole treatment. Asymptomatic increases in liver enzymes may also occur in a sizeable number of patients with fungal disease without any treatment. Symptomatic hepatic reactions have occurred mainly during the first few months of treatment. The estimated incidence of symptomatic reactions is of the order of 1 in 10,000.

Intravenous inoculation of rabbits with spores of Absidia corymbifera strain V.73/8 produced acute phycomycosis and death within 2 to 10 days. Cultural and microscopical examination showed that fungal infection was widespread and involved most organ systems but with particularly extensive lesions developing in the kidneys. The progress of the infection was associated with a raised leucocyte count, an increasing erythrocyte sedimentation rate and significant changes in serum biochemistry. The latter included a decrease in serum iron, zinc, alkaline phosphatase and gamma-glutamyl transpeptidase concentrations but an increase in the synthesis of acute phase proteins and in the phenylalanine:tyrosine ratio and in serum concentrations of copper, magnesium, potassium, lactate dehydrogenase and triglycerides. The serum urea concentration increased substantially during the terminal phase of infection.
