A case of tuberculous pericarditis,the diagnosis of which was complicated by the delay in the rise of adenosine deaminase in the pericardial effusion

An 81-year-old man was admitted to our hospital because of pericardial effusion and sputum PCR positive for Mycobacterium (M.) tuberculosis. Since adenosine deaminase (ADA) value of the pericardial effusion was not high and the sputum smear and culture were negative, anti-tuberculous therapy was not started. Two months later he was admitted again because of high fever and cardiomegaly. Chest computed tomography showed deterioration and the sputum culture revealed M. tuberculosis. The ADA value of the pericardial effusion which was not high at the first admission, was elevated in the second admission, and the diagnosis was made as tuberculous pericarditis two months later. We had better start anti-tuberculous therapy at the first admission, in spite of low value of ADA, as his pericardial effusion showed lymphocyte predominance.     

Case of chronic necrotizing pulmonary aspergillosis successfully treated with a combination of liposomal amphotericin B and itraconazole]

A 58-year-old Japanese man was admitted with high fever, productive cough, marked leukocytosis, and chest X-ray findings of infiltration and fluid levels within lung cysts. He had been treated for pulmonary tuberculosis for 6 months. He was also receiving home oxygen therapy for chronic obstructive pulmonary disease and 10 mg prednisolone daily for rheumatoid arthritis. Aspergillus fumigatus was cultured from bronchial washing fluid and we diagnosed chronic necrotizing pulmonary aspergillosis (CNPA). Micafungin was initially effective but 9 weeks later the symptoms recurred. Micafungin was stopped and after combination therapy of intravenous liposomal amphotericin B and oral itraconazole capsule was started his symptoms and laboratory data markedly improved. Fifteen weeks later his medication was switched to oral voriconazole and he was discharged. CNPA is a chronic infectious disease with poor prognostic and no standard therapy has been confirmed. Each antifungal drug has different mechanisms and sites of action. In the case of treatment failure with several drugs, combination therapy to achieve drug interaction can be a treatment option.     

A surgically treated case of ileus caused by small intestinal tuberculosis during treatment for pulmonary tuberculosis

A 44-year-old man consulted medical clinic, complaining of cough and sputum. Then he was admitted to our hospital, because of positive acid-fast bacilli in his sputum and positive PCR (polymerase chain reaction) for Mycobacterium tuberculosis. Combined use of isoniazid (INH), rifampicin (RFP), ethambutol (EB) and pyrazinamide (PZA) was started. But 4 days after starting treatment, we had to suspend tuberculosis chemotherapy because of hepatopathy. Since then he started to complain epigastralgia and vomiting. Plain abdominal X-ray and abdominal computed tomography (CT) led to a diagnosis of ileus. Inspite of insertion of ileus tube symptoms of ileus did not improve. Small bowl series showed severe stenosis at ileum end, necessitating jejunectomy. Macroscopic study revealed a ring ulcer and multiple epithelioid cell granuloma with Langhans' giant cells was detected histopathologically. PCR for M. tuberculosis of extracts from ileum was positive. Therefore the patient was diagnosed small intestinal tuberculosis. Treatment was continued by the combination of INH, RFP, EB, and the symptoms markedly improved. There have been no sign of recurrence since the end of the 6-month treatment for tuberculosis.     

Plasma Exchange for Acquired Hemophilia: A Case Report

Abstract: A patient with acquired hemophilia complicated with chronic renal failure and lung tuberculosis was successfully treated by consecutive plasma exchange (PE). A 71-year-old man with serious bleeding tendency showed low coagulation factor levels and a high titer of factor VIII (FVIII) inhibitor, and he was diagnosed with acquired hemophilia. Because of the complication of active lung tuberculosis, instead of immunosuppressive therapy, he undertook a series of PE with fresh frozen plasma replacement for 3 months. After the start of PE, his bleeding symptoms and activated partial thromboplastin time (APTT) improved gradually according to the decrease in FVIII inhibitor levels . These results suggest that PE is an effective therapeutic tool for refractory acquired hemophilia.     

Pulmonary disease due to Mycobacterium xenopi in a renal allograft recipient: report of a case and review

A 39-year-old man with pulmonary disease due to Mycobacterium xenopi is described. He had received prednisone and azathioprine for 5 years and prednisone in combination with cyclosporin A for 1 year in an effort to prevent rejection of his renal transplant. Shortly after the renal allograft was removed because of chronic rejection, the patient developed dyspnea and a decrease in vitality. He had no history of preexisting lung disease. A chest roentgenogram showed multiple nodular infiltrates in both lungs. M. xenopi was cultured from three sputum samples. The organism was susceptible to isoniazid, streptomycin, ethambutol, rifampin, pyrazinamide, and ethionamide. The patient was treated successfully with isoniazid, ethambutol, and rifampin for 3 months and with isoniazid in combination with rifampin for an additional 9 months, while he was maintained on continuous ambulatory peritoneal dialysis (CAPD). The literature on mycobacterial disease, especially in renal transplant recipients and patients on CAPD, is reviewed.     

Tuberculosis on regular hemodialysis--a case of pericardial tamponade

The patient presented in this paper had been stable for 3 months after the induction of hemodialysis, when nausea, vomiting and hepatomegaly suddenly developed. A chest film revealed rush cardiomegaly, and massive pericardial effusion was demonstrated by echocardiography. One liter of hemorrhagic fluid was removed by pericardiocentesis and subsequent pericardial drainage under echocardiography. The patient received chemotherapy against pulmonary tuberculosis 30 years ago and calcification on chest film was apparent. Although sputum smear and pericardial effusion was negative for acid-fast organisms, combination therapy was initiated for suspected tuberculosis. The patient recovered completely and 2 months later it was demonstrated that cultures of sputum grew mycobacterium tuberculosis. Tuberculin skin test (PPD), which was negative 2 months previously, converted to positive. Tuberculosis must be considered as a potential cause of pericardial tamponade in patients on regular hemodialysis, and prompt therapy for both cardiac tamponade and the occult infection is warranted.     

Pleural Aspergillosis with Bronchopleurocutaneous Fistula and Costal Bone Destruction: A Case Report

A 65-year-old man who, when young, had had tuberculosis treated by therapeutic pneumothorax, consulted his family physician for a constitutional syndrome and dyspnea. At this time radiologic studies showed left pleural effusion with bilateral calcified plaques, an infiltrate in the upper left lobe, and a picture compatible with aspergilloma, all suggesting semi-invasive aspergillosis. The patient failed to show up for his followup visit, so no therapy could be started or further diagnostic tests ordered. One month later he was admitted to this hospital for a bronchopleural fistula (empyema necessitatis) with subsequent spontaneous hydropneumothorax and costal bone involvement. The patient underwent surgery because of his rapid worsening condition. Biopsy examination revealed a large pleural aspergilloma. Despite immediate antifungal therapy, the patient died. We believe this to be the first report of pleural Aspergillus with a bronchopleurocutaneous fistula and costal bone destruction.     

Development of primary central nervous system lymphoma in an HIV-infected patient after multiple opportunistic infections

A 35-year-old Chinese man presented to medical attention with fever, cough and shortness of breath and HIV infection. His CD4+ lymphocyte count was 28 cells/μL and his HIV viral load was 386,891 copies/mL. Diagnosis of tuberculosis, Pneumocystis jiroveci pneumonia, mycobacterium avium complex, fungal infection and cytomegalovirus retinitis were confirmed according to the symptoms, laboratory results and radiology. After therapy for all these opportunistic infections, his symptoms were relieved. In addition, highly active antiretroviral therapy (HAART) was also initiated two weeks after his admission. The patient had a headache two months after admission and the magnetic resonance image of the brain showed left frontal lobe hypodensity. The patient then accepted brain biopsy and the pathological result proved to be primary central nervous system lymphoma). The patient refused further therapy and lost in our follow-up.     

Evidence of exogenous reinfection and mixed infection with more than one strain of Mycobacterium tuberculosis among Spanish HIV-infected inmates

BACKGROUND: As prisons have a high prevalence of tuberculosis and HIV infection, we studied the possibility of multiple tuberculosis infections in a selected population of HIV-infected inmates. METHODS: Two groups of patients with special characteristics were selected from 226 HIV-infected inmates diagnosed with tuberculosis in the prisons of Madrid (Spain) between 1993 and 1994. The first group contained nine patients who remained culture positive 4 months after the initiation of therapy and the second group contained 28 patients with Mycobacterium tuberculosis isolated from different anatomical sites. DNA typing with IS6110 was performed on all isolates from these patients. In some patients a secondary DNA typing with the plasmid pTBN12 was performed. RESULTS: Two patients from group A had a second M. tuberculosis strain obtained 4 and 18 months after the initial isolate, with different IS6110 and pTBN12 patterns. In one patient the second strain was multidrug resistant and in the other patient both strains had the same drug-susceptible pattern. The clinical and microbiologic evidence in both patients was consistent with the presence of active tuberculosis caused by a new strain of M. tuberculosis. In group B, the isolates from 27 patients shared similar fingerprint pattern; however, in one patient isolates from sputum and urine showed different IS6110 and pTBN12 patterns, although both strains showed the same drug-susceptible phenotype. CONCLUSION: This study provides evidence that HIV-infected inmates living under conditions of high environmental infectivity can be infected with two different strains of M. tuberculosis. This finding has implications for the tuberculosis-control programs in prison.     

A case of multiple bone and joint tuberculosis which had been misdiagnosed as the rheumatoid arthritis and treated with prednisolone for eleven months

A 34-year-old man had a multiple arthralgia for about eleven months. The swelling of his right wrist and foot had appeared in the dorsal side, and he had been misdiagnosed as the rheumatoid arthritis. He was treated with prednisolone in the dosages of 2.5 mg per day for one month, and 10 mg per day for ten months. When he admitted to our hospital, the bone X-ray examinations of the wrist and foot revealed the marked atrophy and destruction of the carpal and tarsal bones. The aspiration fluid from the swelling around his wrist and foot was positive for acid-fast bacilli on smear and Mycobacterium tuberculosis was found on culture. He was treated with isoniazid, rifampicin, ethambutol and pyrazinamide, however, these medication was not adequately effective to his complications of tuberculous arthritis. Curettage, irrigation and synovectomy of his right carpal and tarsal bone were performed in order to control his bone and joint infection. He recovered from his arthritis and tenosynovitis after these operations. The clinical practitioners should not omit tuberculosis from the differential diagnosis of persistent osteoarthralgia.     

Rescue therapy with tacrolimus for a patient with severe ulcerative colitis refractory to combination leukocytapheresis and high-dose corticosteroid therapy

A19-year-old man complaining of severe diarrhea and hematochezia was admitted to our hospital. Endoscopic findings and laboratory data revealed that he had ulcerative colitis (UC). Despite combination therapy with high-dose corticosteroids and intensive granulocytapheresis, his condition did not improve. Therefore, we initiated tacrolimus therapy. Intravenous administration of tacrolimus with a trough level of 10 to 15 ng/ml relieved his abdominal symptoms within 1 week. The patient experienced no UC relapse 1 year after treatment with oral tacrolimus. Tacrolimus is a promising therapy for patients with UC refractory to the combination of high-dose corticosteroids and leukocytapheresis.     

Successful treatment of myelodysplastic syndrome and chronic hepatitis C using combined peginterferon‐α‐2b and ribavirin therapy

We report a patient with myelodysplastic syndrome (MDS) and hepatitis C virus (HCV) infection who was successfully treated with a combination of peginterferon and ribavirin therapy. A 65‐year‐old man was referred to our hospital for treatment of chronic hepatitis C and close examination of pancytopenia. MDS of “refractory cytopenia with multilineage dysplasia” was diagnosed on the basis of bone marrow findings. Although the patient was not a good candidate for interferon (IFN) therapy because of his pancytopenia, we decided to proceed with IFN therapy for the following reasons: his elevated transaminases could not be controlled; he had a high possibility of recovery from chronic hepatitis C in consideration of his HCV genotype 2a and relatively low RNA titer; and his pancytopenia was expected to worsen in the future. After combination peginterferon/ribavirin therapy, the patient achieved sustained viral response, and the bone marrow findings showed neutrophils with normal granulation and megakaryocytes with normal morphological features. Additionally, the normal 46, XY karyotype converted from 45, X0 which was found before IFN therapy. This suggested that the patient's MDS was completely resolved.     

Pancytopenia responding to treatment of hyperthyroidism: a clinical case and review of the literature

A 46-year-old-man received high dose chemotherapy and an autologous stem-cell transplant for multiple plasmacytoma. He had a prolonged period of pancytopenia post-transplantation, which was thought to be due to a suboptimal dose of transplanted stem cells in combination with the effects of interferon therapy and an altered bone marrow microenvironment. Twenty-eight months after the transplant he was found to be hyperthyroid. Anti-thyroid therapy has led to a sustained improvement in his pancytopenia.     

Central nervous system (CNS) tuberculosis following allogeneic stem cell transplantation

Tuberculosis is an uncommon infectious complication after stem cell transplantation. We report a patient who presented with a brain mass, 3 months after pulmonary tuberculosis had been diagnosed and while he was receiving triple antituberculous therapy. He had extensive chronic GVHD. The diagnosis was made after biopsy of the lesion. The cerebral mass was excised, antituberculous treatment was maintained and the patient made a complete neurologic recovery. Six months later, he died of gram-negative septic shock. Mycobacterial infections should be considered in allograft recipients with chronic GVHD and solid lesions in the brain.

Recurrent Mycobacterium xenopi infection in a patient with rheumatoid arthritis receiving etanercept

A case of recurrent Mycobacterium xenopi infection presenting as Pott's disease in a patient receiving etanercept for severe rheumatoid arthritis is described. A 49-y-old Caucasian male had received a total of 11 months of anti-mycobacterial therapy for hip infection acquired 15 months earlier; he presented with progressive back pain, which was diagnosed as Pott's disease. He had been treated with etanercept in addition to his prior immunosuppressive agents after the diagnosis of hip infection.     

A child case of Down's syndrome with intestinal tuberculosis and tuberculous pleuritis

A 13 year-old girl with Down's syndrome was admitted to our hospital with a very positive reaction to PPD 5TU, abnormal shadow on the chest X-ray films and diarrhea. She suffered from acute enterocolitis one year ago, and then has been complaining of abdominal pain, appetite loss, and weight loss for a year. After admission, she was diagnosed as tuberculous pleuritis and suspected intestinal tuberculosis by laboratory examination. She recovered without sequelae by the combination therapy of SM, INH, and RFP, and was discharged after 5 months. The diagnosis of intestinal tuberculosis was confirmed by Colon Fiberscopy showing ulceration at the ileocecal region and simultaneous biopsy showing granuloma. Surgical treatment was not reserved, because she had no complications namely perforation and fistulization. We estimated that the onset of intestinal tuberculosis coincided with the acute enterocolitis which she had about one year ago. We realized the importance of paying attention to intestinal tuberculosis in the differential diagnosis of enterocolitis, especially regional enteritis. Furthermore, in the therapy of the immunocompromised host including Down's syndrome, we must pay attention to extra-pulmonary tuberculosis. Efficiency of SM for intestinal tuberculosis with complications was confirmed.     

A successfully treated case of infective endocarditis due to Candida tropicalis

A 34-year-old man, a heavy drinker, was admitted with a high fever and hematuria two months previously. Surgery was performed for acute sever pancreatitis and postoperatively antibiotics were administered with intravenous hyperalimentation. After discharge he was readmitted and infective endocarditis was strongly suspected because of high fever, hematuria, Osler's nodes, Janeway's lesions, splinter hemorrhages and mitral regurgitation. Penicillin G in combination with Gentamycine therapy was started on the first hospital day. On the second hospital day, blood culture revealed Candida tropicalis so Miconazole therapy was commenced. On the forth hospital day, he underwent surgery for replacement of a mitral prosthesis with a prosthetic valve because he had embolus in the radial artery. Despite intensive antifungal therapy, he showed no improvement in clinical symptoms. Then we changed the antifungal drug from Miconazole to Amphotericin B and 5-fluorocytosine. On the 109th hospital day, his clinical symptoms improved. Antifungal therapy was halted and at present 10 months later, he is healthy.     

Multilocular colorectal tuberculosis and hypogammaglobulinemia

We present the case of a young male patient admitted for weight loss, diarrhea and rectal bleeding. The patient belonged to a low social class and had associated hypogammaglobulinemia. The endoscopy revealed different localized ulcerations of he rectum and a stenosis. By barium enema and hydrosonography multiple stenotic lesions were observed. The pathological examinations detected lesions suggestive for intestinal tuberculosis. A specific therapy led to the improvement of his general state and to the disappearance of diarrhea and rectal bleeding.     

A patient with de novo tuberculosis during anti-tumor necrosis factor-alpha therapy illustrating diagnostic pitfalls and paradoxical response to treatment.

In 2005, a 24-year-old man with Crohn disease who had been treated with infliximab for several months was exposed to an individual with smear-positive tuberculosis. Soon after exposure, he complained of malaise, dry cough, and weight loss. Despite normal chest radiograph findings and negative tuberculin skin test results, tuberculosis was considered to be the most likely diagnosis. The results of a whole-blood assay for detection of interferon- gamma production in response to Mycobacterium tuberculosis-specific antigen were positive. Acid-fast staining and polymerase chain reaction of bronchoalveolar lavage fluid samples had negative results, but M. tuberculosis was cultured. After the initiation of 4 antitubercular drugs and the discontinuation of infliximab therapy, the patient developed an immune reconstitution syndrome accompanied by enlarged mediastinal lymph nodes and multiple intrapulmonary miliary lesions. This case of de novo tuberculosis during anti-tumor necrosis factor alpha treatment illustrates the uncharacteristic presentation of the disease and the elusiveness of the diagnosis, as well as the fact that discontinuation of anti-tumor necrosis factor alpha treatment can be accompanied by an immune reconstitution syndrome similar to that observed in human immunodeficiency virus-infected individuals with tuberculosis.     

A case of Poncet's disease (tuberculous rheumatism) in a patient with chronic renal failure undergoing hemodialysis therapy]

A 78-year-old man who was undergoing hemodialysis therapy was admitted to our hospital because of sore throat, remittent cervical lymphadenopathy, and polyarthritis over the preceding 4 weeks. On admission, he had bilateral cervical lymphadenopathy. He complained of arthralgia associated with tenderness, warmth and swelling of both elbows, left side wrist and left shoulder joint. The C-reactive protein level on admission was 15.3 mg/dl. Rheumatoid factor, antinuclear antibodies, tuberculin skin test and blood culture were negative. Joint fluid was not aspirated. Radiographs of the joints did not reveal any abnormalities. Acid-fast bacilli were demonstrated in the smear of the cervical lymph node with a fluorochrome rhodamine-auramine stain. Mycobacterium tuberculosis DNA was identified by polymerase chain reaction. We found the presence of caseating granuloma on the biopsy specimens and M.tuberculosis was detected from culture. At that point, we diagnosed this patient as having tuberculous lymphadenitis. His general symptoms resolved rapidly after starting with a three-drug regimen consisting of isoniazid, rifampin and pyrazinamide. His polyarthritis also improved dramatically. Finally we considered that his polyarthritis was tuberculous rheumatism, also called Poncet's disease. Poncet's disease is characterized by sterile polyarthritis during active tuberculosis infection. It is considered a reactive arthritis, which is a different entity from tuberculous arthritis. Although this is a rare disease, we should be aware of it in hemodialysis patient clinics, because the incidence of tuberculosis infection has been reported to be increasing in patients with end-stage renal failure.
