The combined treatment of peptic ulcer with the differentiated use of nontraditional physiotherapeutic methods

Efficiency was studied of multimodality treatment of 586 patients with ulcer disease. Of these, 110 had gastric ulcer, 460 patients had duodenal ulcer, sixteen were suffering from both gastric and duodenal ulcer. 275 patients (46.8%) had various concurrent chronic disorders involving cardiovascular system and alimentary canal. Three groups of patients were identified: those receiving magnetoresonance therapy apart from conventional antiulcer therapy (n = 89), those undergoing laser therapy (n = 170), those exposed to hyperbaric oxygenation (HBO), variable magnetic field (VMF) and acupuncture (AP) according to generally accepted techniques. In the control group, drug therapy promoted ulcer healing in 73.3% of patients, whereas multimodality treatment involving MRT induced healing in 80.6% that of incorporating computer-aided laser therapy led to healing in 85.7 to 89.4%. HBO, VMF and AP group demonstrated healing in 92.4 to 93.7%.     

Direct detection of Mycobacterium tuberculosis using polymerase chain reaction assay among patients with hepatic granuloma

BACKGROUND: In liver tuberculosis, demonstration of acid bacilli by conventional methods remains futile. Since the definitive diagnosis of liver tuberculosis is based on the histologic evidence of granulomatous process with caseation necrosis, seen in only a third of cases, the diagnosis is made retrospectively by response to empirical anti-tuberculous drug therapy. AIMS: Our objective is to establish a polymerase chain reaction assay for detection of Mycobacterium tuberculosis affecting the liver using the paraffin-embedded liver biopsy specimens obtained from patients with hepatic granulomas. METHODS: As positive control, patients having either "definitive" (n=8) or "presumptive" (n=9) tuberculosis on the basis of clinical, microbiological, histologic data and their positive response to empirical treatment of anti-tuberculous drugs were used. Patients with hepatic granulomas secondary to schistosomiasis (n=6), sarcoidosis (n=2) and other liver diseases (n=10) were used as negative control. RESULTS: Of those patients who were diagnosed as having "definitive" and "presumptive" liver tuberculosis, positivity by one-step polymerase chain reaction was 100% and 44%, respectively. Using the nested polymerase chain reaction, positivity increased to 78% with "presumptive" liver tuberculosis. In contrast, the polymerase chain reaction assays were negative among all patients with hepatic granuloma due to non-tuberculous-in-origin and other liver diseases. CONCLUSIONS: The overall positivity of this polymerase chain reaction assay (88%) compares favorably with that of other conventional methods (12%). Thus, this polymerase chain reaction assay may be a reliable diagnostic tool for liver tuberculosis in a patient population in which the prevalence of diseases associated with hepatic granuloma is common.     

Radiographic spectrum of adult pulmonary tuberculosis in a developed country

SETTING: Bispebjerg Hospital, Department of Pulmonary Medicine P. The referral centre of adult tuberculosis in the municipality of Copenhagen, Denmark. OBJECTIVE: To evaluate the radiographic spectrum of pulmonary tuberculosis (TB) in adults in a low-prevalence country and to correlate radiographic appearances with bacteriological results, clinical and demographic data. DESIGN: Retrospective review of medical files on 548 cases with pulmonary TB according to the criteria of WHO. RESULTS: Usual radiographic pattern of reactivating TB, with upper lobe involvement, was found in 92% (n = 504), eight percent (n = 44) showed unusual X-ray patterns for adults, such as isolated lower lobe infiltrations (n = 19), hilar adenopathy (n = 10), miliary TB (n = 7), tuberculoma (n = 2), pleural effusion (n = 1) and normal chest X-ray (n = 3). Eight-nine percent of cases with cavitary lesions were positive by microscopy. CONCLUSION: The risk of missing a diagnosis of pulmonary TB may be high if patients present with an X-ray unusual for TB, but this is fortunately seen only in 8% of cases of pulmonary tuberculosis. Unusual X-ray is more commonly found in patients with concomitant disease, such as diabetes and cancer. If chest X-ray shows cavities, but the smear is negative for Mycobacterium, TB is unlikely and further diagnostic procedures should be performed without waiting for culture results.     

Therapy for the maintenance of remission in sixty-five patients with generalized Wegener's granulomatosis. Methotrexate versus trimethoprim/sulfamethoxazole

OBJECTIVE: To compare the efficacy of low-dose intravenous (IV) methotrexate (MTX; 0.3 mg/kg once weekly), both with and without concomitant prednisone, versus daily oral trimethoprim/sulfamethoxazole (T/S; 160 mg of trimethoprim + 800 mg of sulfamethoxazole twice a day), with and without prednisone, in maintaining remission in patients with generalized Wegener's granulomatosis (WG). METHODS: In this study, 65 patients with generalized WG whose disease had entered remission with cyclophosphamide (CYC) and prednisone therapy were started on one of the following remission-maintenance regimens: MTX alone (group A; n = 22), T/S alone (group B; n = 24), MTX plus concomitant prednisone (group C; n = 11), and T/S plus concomitant prednisone (group D; n = 8). Clinical, radiographic, and seroimmunologic data were evaluated to assess the efficacy of the 4 regimens and to seek possible predictive factors concerning outcome in each group. RESULTS: Partial or complete remission was maintained in 86% of the patients in group A, but in only 58% of those in group B (P < 0.05). In group C, 91% of patients remained in remission, which is in sharp contrast to group D, in which all patients experienced a relapse after a median of 14.5 months (P < 0.005). Side effects occurred twice as often with MTX (n = 12) as with T/S (n = 6) treatment and could usually be resolved by supplemental folinic acid. Two patients taking MTX and 3 patients taking T/S were withdrawn from the study medication because of side effects. In none of the patients were the adverse effects life threatening. No statistically significant factors predictive of poor outcome emerged in any group. CONCLUSION: Low-dose MTX was found to be superior to T/S for the safe and effective maintenance of remission in patients with generalized WG. The use of concomitant prednisone was not associated with a worse outcome with MTX treatment. Since T/S, especially with concomitant prednisone, seemed to increase the chance of relapse, neither T/S alone nor T/S plus prednisone can be recommended for the maintenance of remission in patients with generalized WG.     

Cryptococcosis in HIV infection of man: an epidemiological and immunological indicator?

Cryptococcosis is an epidemiological and immunological indicator due to the absence of Cryptococcus neoformans as a saprophyte in immunocompetent humans and the advantage of specific C. neoformans culture. On this basis, a report is presented on the CD4 lymphocyte count of 36 AIDS patients suffering from cryptococcosis and other concomitant or missing opportunistic AIDS-defining infections. In 26 out of 36 patients, i.e. 72%, a CD4 lymphocyte count of < or = 50/microL (mean value 39.5%) was found. Cryptococcosis as the sole opportunistic infection was diagnosed in 5 cases (13.9%). In 31 cases, various combinations of AIDS-associated diseases were found: Pneumocystis carinii pneumonia (PCP) (n = 19), cytomegalovirus infection (CMV) (n = 10), Kaposi's sarcoma (n = 6), Mycobacterium avium intracellulare infection (MAI) (n = 5), pneumonia (n = 2), toxoplasmosis (n = 2), Candida esophagitis (n = 1), tuberculosis (n = 1), lambliasis (n = 1), salmonellosis (n = 1) and wasting syndrome (n = 5). The conspicuous simultaneous occurrence or succession of pneumocystosis and cryptococcosis and the contrasting absence of aspergillosis and mucormycosis (zygomycosis) are commented. Based on the present observations in HIV-infected persons in Berlin, a CD4 lymphocyte count of < 150/microL may be used as a parameter indicating a predisposition for cryptococcosis as an airborne AIDS-defining infection. Attention is drawn to bird droppings as the sole habitat of C. neoformans and accidental niche of various other microorganisms.     

Cytarabine and cisplatin as salvage therapy in patients with metastatic colorectal cancer who failed 5-fluorouracil + folinic acid regimen. French Northern Oncology Group

The combination of CDDP and ARA-C has shown some clinical efficiency as first-line therapy in advanced colorectal cancer. Our study was aimed to evaluate the therapeutic activity of this combination in advanced colorectal cancer who failed 5-fluorouracil (FU) and folinic acid (LV) regimen. Seventeen patients with measureable metastatic colorectal cancer who failed 5FU-LV therapy as first line (n = 14) or second line treatment (n = 3), entered the study. Three patients who recurred during adjuvant treatment with 5FU and levamisol, were also included. Median age was 59.5 (40-69). Performance status was as follows: 0 (n = 5), 1 (n = 11), 2 (n = 3), 3 (n = 1). Site of metastases included liver (n = 16), lung (n = 7), abdomen (n = 2), pelvic recurrences (n = 2), cutaneous (n = 1). Seven patients had 2 metastatic sites and two 3. The treatment was given as follows: ARA-C 75 mg/m2/day, days 1-3, followed 1 hour later by CDDP 30 mg/m2/day, days 1-3, every 28 days. The median number of cycles was 3 (range: 1-6 cycles). All patients but one were evaluable for both response and toxicity. Of these patients, 50% experienced severe hematologic toxicity and nonhematologic toxicity mainly consisted of fatigue and/or vomiting. No objective response was observed, but there were 3 stabilizations and 16 progressive diseases. Median time to progression was 10 weeks. Thus, the CDDP/ARA-C regimen is not of clinical value as salvage therapy in advanced colorectal cancer because of its toxicity and its lack of efficiency.     

Water jet guided Nd:YAG laser coagulation--its application in the field of gastroenterology

With the water jet guided laser, a comparatively new transmission system has become available, with the aid of which the laser beam is conducted from the end of the transmission fibre of the conventional light guide system to the target tissue via a water jet. The extra costs of this modality are low. The technique is easy to apply, and is associated with a number of technical advantages, such as absence of smoke and carbonisation, reduction in organ distension, etc. The water jet guided laser brings about volume coagulation in the deeper layers of the wall, with concomitant oedema and hyperaemia in the periphery. In a randomised, prospective controlled study, 89 patients with gastroduodenal ulcers bearing a visible vessel were treated with the Nd:YAG laser (wavelength 1.064 nm), 43 with the non-contact, and 46 with the water jet guided modality. In the water jet group a smaller number of bleedings were induced (p < 0.05) and fewer failures, emergency operations and deaths occurred. The technical advantages of the method, together with the results of treatment in 20 tumour patients with adenomas (n = 6) and adenocarcinomas in the colorectum (n = 14) with readily achievable tumour debulking (n = 13) or complete eradication (n = 7), suggest that the use of the water jet guided laser might also be appropriate for the treatment of tumours.     

Arterial disease and thrombosis in the antiphospholipid syndrome: a pathogenic role for endothelin 1

PURPOSE: It has been proposed that inferior vena cava filter placement should be the initial treatment of deep venous thrombosis (DVT) or pulmonary embolus (PE) in patients with coexisting malignant disease. We have chosen instead to selectively place filters only in patients with either a contraindication to anticoagulation therapy or a subsequent complication from anticoagulation therapy. The treatment efficacy and mortality rates in patients with concomitant malignant disease and venous thromboembolism using this approach was determined. METHODS: We retrospectively reviewed all patients at our institution with malignant disease in whom venous thromboembolism developed between August 1991 through August 1996 and identified 166 patients with PE (n = 8), DVT (n = 147), and DVT/PE (n = 11). Of these patients, 138 (83.1%) were initially treated with anticoagulation therapy, and 28 (16.9%) had primary filter placement because of contraindications to anticoagulation therapy (10 for intracranial tumors, 11 for recent or upcoming operations, 6 for recent hemorrhage, and 1 for a malignant bloody pericardial effusion). RESULTS: Thirty-two (23%) of the 138 patients who initially underwent anticoagulation therapy subsequently required a filter for the following reasons: bleeding (n = 15, 10.9%); recurrent thromboembolism (n = 6, 4.3%); heparin-induced thrombocytopenia (n = 1, 0.7%); and perceived high risk for bleeding with continued anticoagulation therapy (n = 11, 8%). Both bleeding and recurrent thromboembolism developed in 1 patient. Sixty patients (36%) received filters. No major technical complications occurred from filter placement. Major recurrent thromboembolic complications developed in 10 patients: DVT (n = 6, 10%), PE (n = 2, 3.3%), inferior vena cava thrombosis and phlegmasia cerulea dolens (n = 1, 1.7%), superior vena cava thrombosis (n = 1, 1.7%). Venous gangrene developed in 1 patient with DVT. The 1-year actuarial survival rates for patients treated with filter and anticoagulation therapy were 35% and 38%, respectively (P = NS). CONCLUSION: In summary, our experience suggests that 64% of patients with malignant disease and venous thromboembolism are effectively treated with anticoagulation alone; 17% require primary filter placement for standard indications, and an additional 19% require subsequent filter placement because of complications (primarily bleeding) or failure of anticoagulation therapy. Although technical complications of filter placement are low, serious life-threatening or limb-threatening thromboembolic complications developed in 17% of patients. Survival was poor in all patients, regardless of treatment. These data support a conservative approach of routine anticoagulation therapy with selective filter placement.     

Expression of type II cGMP-dependent protein kinase in rat kidney is regulated by dehydration and correlated with renin gene expression

To define the current indications for surgical management of pleuropulmonary tuberculosis and analyze the results of operative procedures, the records of 59 patients operated on between January 1987 and December 1993 were reviewed. Three patient categories were defined. Group I patients (n = 25) underwent operation for diagnostic purposes: solitary mediastinal node or mediastinal adenopathy associated with pulmonary lesions (n = 10), pulmonary infiltrates (n = 4), pulmonary nodules or masses (n = 10), or chronic pleurisy (n = 1). Postoperative mortality and morbidity rates in this group were both 4%. Group II patients (n = 18) underwent operation for active lesions: intrapulmonary cavity (n = 6), destroyed lung parenchyma (n = 6), or chronic loculated pleural effusion (n = 6). Postoperative morbidity and mortality rates were 16.6% and 5.5%, respectively. Group III patients (n = 16) underwent operation for a complication of therapy or for sequelae of previously "cured" tuberculosis: calcified pyothorax (n = 8), empyema (n = 2), fistulized nodes (n = 2), bronchiectasis (n = 3), or aspergilloma (n = 1). Morbidity and mortality rates in this group were 31.25% and 12.5%, respectively. Surgery continues to have both diagnostic and therapeutic indications for management of pleuropulmonary tuberculosis, despite the morbidity and mortality rates associated with operative procedures.     

Architecture. The Studio. The concept of the Arpage residences]

The outcomes of treatment of 110 homeless patients with tuberculosis admitted to Moscow City Clinical Hospital No. 7 in 1993-1996 were followed up. All homeless persons have various concurrent diseases, such as alcoholism, chronic nonspecific diseases of the lung, diseases of the cardiovascular system, kidney, liver, etc., which require their treatment by physicians of different disciplines. Good results of treating the homeless may be obtained when rehabilitative services are used and hospital treatment is performed for at least 4 months. All homeless patients who admitted to general hospitals are to be physically, roentgenologically, and bacterioscopically examined whether they have tuberculosis.     

Application of rectal stents for palliation of obstructing rectosigmoid cancer

BACKGROUND: The rationale of palliative endoscopic treatment is to avoid a colostomy in patients with advanced disease and limited life expectancy. This study was conducted to evaluate the role of endoscopic stent implantation for palliation of obstructing rectal cancer. METHODS: Overall, 19 patients (aged 47-87 years) with nonresectable or metastatic rectal cancer were treated by stent insertion after laser recanalization or dilation. Three types of stents, i.e., plastic tubes (n = 8), self-expanding mesh stents (n = 6), and endocoil stents (n = 5), were used to maintain luminal patency. RESULTS: Endoscopic stent implantation was successfully performed in all 19 patients. Long-term luminal patency and satisfactory bowel function were achieved in 16 of 19 patients (84%). After a median follow-up of 6 months, eight of the patients have died and eight are still alive without evidence of recurrent obstruction. Dislocation of the endoprosthesis occurred in two of eight plastic tubes and one of five mesh stents. Recurrent obstruction due to tumor ingrowth was only observed in patients treated with self-expanding mesh stents (n = 2). In spite of reinsertion and laser therapy a colostomy was required in three of 19 patients. There was no evidence of treatment failure in five patients who received endocoil stents. None of the patients experienced serious complications related to the endoscopic procedure. CONCLUSIONS: Endoscopic stent implantation seems to be a safe and efficient palliative approach to selected patients with obstructing rectal cancer. Currently, self-expanding coil stents are superior to other devices because of lower risk of dislocation and tumor ingrowth.     

Indication for surgery of asymptomatic carotid lesions

The incidence of cerebrovascular diseases with transient or persistent neurologic dysfunction has increased significantly. Although patients with symptomatic carotid artery stenosis clearly benefit from operative therapy, the indication to prophylactic surgery of asymptomatic carotid lesions however is still controversial. Based on data from a recently completed prospective randomized study and on analysis of the literature the indication and results of surgical treatment of asymptomatic stenoses of the carotid arteries are discussed. From 1970 to 1990 a total of 744 uni-or bilateral reconstructions of the internal carotid artery were performed in 631 patients. The perioperative morbidity (permanent neurologic deficiency) and mortality was 1.1% (n = 8) resp. 0.8% (n = 6). During the follow up period up to 18 years another 9 patients suffered from stroke (1.2%). The annual stroke incidence amounted to 0.2%. An important prerequisite for surgery is the so called critical internal carotid artery stenosis, implying reduced cerebral vasomotor reactivity or high embolic risk of an ulcerative plaque. Proper selection of patients (exclusion of multiple concomitant diseases) and an experienced team of vascular surgeons with operative morbidity and mortality below 1-2% validates surgical treatment of asymptomatic carotid artery stenoses.     

New aspects in the etiopathogenesis of colorectal cancer

The paper analyzes the examination of 240 patients with alleviating pulmonary tuberculosis (follow-up group 2) and provides clinical and social characteristics of this group of patients who had poor social factors, such as a social behaviour, alcoholism, unemployment, etc. Ninety one patients had various concomitant visceral diseases. During treatment of pulmonary tuberculosis, most patients developed profound residual changes. This all requires more thorough follow-up while performing seasonal drug regimens and other prophylactic measures in Group 2 patients.     

Ultrasound guided fine needle aspiration cytology in abdominal tuberculosis

Although barium studies and CT are useful in assessing abdominal pathology in tuberculosis, imaging findings are not always specific and a histopathological or bacteriological confirmation is often required. The aim of the present study was to evaluate the role of ultrasound (US) guided fine needle aspiration cytology (FNAC) in the diagnosis of abdominal tuberculosis in patients with non-palpable lesions detected on US/CT. FNAC was performed on 31 sites in 30 patients. The sites included enlarged lymph nodes (n = 14), focal lesions in liver (n = 2) and spleen (n = 8), and thickened bowel in the ileocaecal region (n = 7). The results were classified cytomorphologically into four groups: (1) definite evidence of tuberculosis; (2) presumptive evidence of tuberculosis; (3) suggestive of tuberculosis; and (4) negative for tuberculosis. 18 of the 31 FNACs (58%) revealed a positive diagnosis of tuberculosis (definite evidence in nine patients and presumptive evidence in nine patients). 13 of the 31 FNACs (42%) showed either necrosis alone (n = 4) or negative results (n = 9). Zeihl-Neelson staining for acid-fast bacilli on direct smear was positive in only nine patients (29%). Splenic and lymph nodal FNAC had a high sensitivity (87.5% and 78.6%, respectively) in the diagnosis of tuberculosis. None of the bowel and liver FNACs was diagnostic. No complications were encountered. US guided FNAC offers a safe and accurate method of achieving a diagnosis in patients with suspected abdominal tuberculosis who present with radiologically demonstrable but non-palpable lesions, especially those involving lymph nodes and spleen.     

Family-focused treatment versus individual treatment for bipolar disorder: Results of a randomized clinical trial.

Recently hospitalized bipolar, manic patients (N=53) were randomly assigned to a 9-month, manual-based, family-focused psychoeducational therapy (n=28) or to an individually focused patient treatment (n=25). All patients received concurrent treatment with mood-stabilizing medications. Structured follow-up assessments were conducted at 3-month intervals for a 1-year period of active treatment and a 1-year period of posttreatment follow-up. Compared with patients in individual therapy, those in family-focused treatment were less likely to be rehospitalized during the 2-year study period. Patients in family treatment also experienced fewer mood disorder relapses over the 2 years, although they did not differ from patients in individual treatment in their likelihood of a first relapse. Results suggest that family psychoeducational treatment is a useful adjunct to pharmacotherapy in decreasing the risk of relapse and hospitalization frequently associated with bipolar disorder.

Evidence that the TRH-like peptide pyroglutamyl-glutamyl-prolineamide in human serum may not be secreted by the pituitary gland

A prospective, randomized, placebo-controlled, double-blind, parallel-group, 6-month study assessed the efficacy and safety of ropinirole, a nonergoline D2-dopamine agonist, in patients with early Parkinson's disease (n = 241; Hoehn & Yahr stages I to III) with limited or no prior dopaminergic therapy. Patients (mean age, 62.8 years), stratified by concomitant use of selegiline, were randomized to ropinirole (n = 116) or placebo (n = 125). The starting dose of ropinirole was 0.25 mg tid with titration to at least 1.5 mg tid (maximum dose, 8 mg tid). Primary efficacy endpoint was the percentage improvement in Unified Parkinson's Disease Rating Scale (UPDRS) motor score. Ropinirole-treated patients had a significantly greater percentage improvement in UPDRS motor score than patients who received placebo (+24% vs -3%; p < 0.001). Ropinirole was well tolerated and patient withdrawals were infrequent. Most adverse experiences were related to peripheral dopaminergic activity. Ropinirole monotherapy is an effective and well-tolerated therapeutic option for treatment of early Parkinson's disease.     

Developing software in the Third World: Papua New Guinea provincial health information system

We report the case history of a 75-year-old female patient suffering from extensive gastric antral vascular ectasia (watermelon stomach) with portal hypertension in alcoholic liver cirrhosis. Iron deficiency anaemia, due to chronic blood loss from the antral lesions, required repeated transfusions. Conservative treatment failed, but a surgical intervention (antrectomy) was discarded in view of concomitant diseases. Endoscopic laser photocoagulation therapy with a Nd:YAG-laser eradicated the characteristic antral lesions, which was accompanied by a significant reduction of transfusion requirements. No relapse has been observed since then. Endoscopic laser photocoagulation appears to be an efficacious and safe alternative in the treatment of gastric antral vascular ectasia.     

High incidence of bacteriuria following renal transplantation in children

STUDY OBJECTIVE: To delineate the course of serum adenosine deaminase (s-ADA) in patients with tuberculosis who are receiving effective therapy. SETTING: A medical ward and an outpatient clinic in a general hospital. PATIENTS: Twenty-five immunocompetent patients with pleural or pulmonary tuberculosis. INTERVENTIONS: All patients received standard chemotherapeutic regimens with isoniazid, rifampin, and pyrazinamide. MEASUREMENTS AND RESULTS: Six measurements of several variables, including s-ADA, were carried out at different periods of time during the 6 months of follow-up. There were no significant differences in s-ADA values between sexes and there was no significant correlation with age or with the other variables analyzed. There was a significant decline in the s-ADA values during the first 2 months in the patients as a whole (p=0.04), followed by a stabilization of the s-ADA activity. This decline was due to a marked decrease in the s-ADA in the 13 patients (52%) who had initial high levels of the enzyme (p=0.03), whereas there were no changes in those patients with normal initial levels (p=0.27). Patients with increased s-ADA activity at the time of the first measurement reported symptoms for a longer period than patients with normal s-ADA (median, 15 vs 10 days; p=0.02). CONCLUSIONS: s-ADA levels in patients with tuberculosis decrease during the initial months of effective treatment. Perhaps this decrease might reflect the normalization of the altered lymphocyte turnover induced by tuberculosis. The measurement of s-ADA could be of some help to evaluate the response to therapy, particularly in those patients with increased values of the enzyme.     

Interpreting outcomes

Analysis of clinical forms of tuberculosis in patients of a pulmonological showed that 65.5% of them had infiltrative tuberculosis, 13.8% fibrocavernous tuberculosis, 10.4% disseminated tuberculosis, 6.9% focal tuberculosis, and 1.7% tuberculoma. It was ascertained that in these patients destructive tuberculous changes were common and occurred in 67.2% and tuberculosis was concurrent with other lung diseases in 70.7%. This follows that special attention should be given to the patients of pulmonological hospitals and sputum tests for mycobacteria are to be performed 3 times.     

Quantification and localization of hyaluronan in a PTFE polymer implanted in the corneal stroma

OBJECTIVE: To determine outcome following treatment of refractory Crohn's disease with intravenous (i.v.) cyclosporine (CYA). METHODS: The medical records of 18 patients with refractory Crohn's disease treated with i.v. CYA were reviewed. Nine patients had refractory inflammatory Crohn's disease and nine patients had complex fistulizing Crohn's disease. All patients were initially treated with i.v. CYA (4 mg/kg/day). Patients who responded were converted to standard oral CYA. Patient outcomes were classified as complete response, partial response, or nonresponse. RESULTS: Four of nine patients with severe inflammatory Crohn's disease and seven of nine patients with fistulizing Crohn's disease had a partial response to i.v. CYA. Four of four responding patients in the inflammatory group and four of six responding patients in the fistulizing group (plus one initial nonresponder) maintained or improved their response during oral CYA therapy. After discontinuing oral CYA, all four patients in the inflammatory group and five of seven patients in the fistulizing group relapsed despite 1-17 wk of concomitant treatment with azathioprine or 6-mercaptopurine (AZA/6MP). Two patients who received overlapping CYA and AZA/6MP for 17 and 23 wk maintained long-term responses. CYA toxicity was minimal: reversible nephrotoxicity (n = 2), headache (n = 2), oral candidiasis (n = 1), paresthesia (n = 2). CONCLUSIONS: I.v. CYA appears to benefit both refractory inflammatory and fistulizing Crohn's disease. Most patients who respond to i.v. CYA will maintain their response during oral CYA therapy. However, the majority of these patients relapse when oral CYA is discontinued, probably because of inadequate duration of overlap with the slow acting maintenance drugs, AZA/6MP.
