Background and Aim: Sensitivity of tuberculin skin test [TST] during screening for latent tuberculosis infection [LTBI] is affected by steroid and/or immunosuppressant therapy. The aim of this study was to compare performance of the two-step TST in inflammatory bowel disease patients immediately before anti-tumour necrosis factor [TNF] therapy as part of routine screening for LTBI vs control patients when the TST was carried out at an early stage. Methods: In this multicentre prospective controlled study, we evaluated the performance of two-step TST with 5-mm threshold...

Kikuchi-Fujimoto disease (KFD) is a benign, self-limiting disease characterized by histiocytic necrotising lymphadenitis. Though several viral agents or an autoimmune etiology has been proposed as causative, the exact cause remains unknown. It has a female predilection and most commonly seen among young Asian people. Patients usually present with a febrile illness and the presence of lymphadenopathy may provide a clue to diagnosis. The most common site of lymphadenopathy is cervical lymph nodes while intra-abdominal involvement is uncommon...

Buddleja saligna (family Buddlejaceae) is a medicinal plant endemic to South Africa. Two isomeric pentacyclic triterpenes, oleanolic acid and ursolic acid, were isolated from the leaves of B. saligna using silica gel column chromatography. Compounds oleanolic acid and ursolic acid were subjected to derivatization with acetic anhydride in the presence of pyridine to obtain oleanolic acid-3-acetate and ursolic acid-3-acetate, respectively. The structures of these compounds were fully characterized by detailed nuclear magnetic resonance (NMR) investigations, which included (1)H and (13)C NMR...

Fever of unknown origin is a rare condition after solid organ transplant and is generally associated with atypical infections (eg, tuberculosis, fungal infections) and/or lymphoproliferative disorders. Here, we present a kidney transplant patient with a late diagnosis of E148Q mutation-positive familial Mediterranean fever as the cause of fever of unknown origin. A 22-year-old female patient with a previous history of 4 years of hemodialysis and unknown primary renal disease received a deceased-donor kidney transplant at our center 5 years previously...

The Philippines is a low middle-income, tropical country in Southeast Asia. Infectious diseases remain the main causes of morbidity, including tuberculosis. AIDS/HIV prevalence is still low at <1%, but is rapidly increasing. Fungal disease surveillance has not been done, and its burden has never been estimated. This becomes more important as the population of immunocompromised patients increases, drawn from patients with AIDS, TB, malignancies, and autoimmune diseases requiring chronic steroid use. Using the methodology of the LIFE program ( www...

The C-19 steroids 4-androstene-3,17-dione (AD), 1,4-androstadiene-3,17-dione (ADD) or 9α-hydroxy-4-androstene-3,17-dione (9OH-AD), which have been postulated as intermediates of the cholesterol catabolic pathway in Mycobacterium smegmatis, cannot be used as sole carbon and energy sources by this bacterium. Only the ΔkstR mutant which constitutively expresses the genes repressed by the KstR regulator can metabolize AD and ADD with severe difficulties but still cannot metabolize 9OH-AD, suggesting that these compounds are not true intermediates but side products of the cholesterol pathway...

Tuberculous peritonitis is rare in the United States but continues to be reported to occur in certain high-risk populations, which include patients with AIDS or cirrhosis, patients on continuous ambulatory peritoneal dialysis, recent immigrants from areas of high endemicity, and those who are immunosuppressed. The diagnosis of this disease requires a high clinical index of suspicion and should be considered in the differential of ascites with a lymphocyte predominance and serum-ascitic albumin gradient of <1...

Necrotizing granulomatous diseases of the lungs are usually dependent on a narrow range of differential diagnoses. Tuberculosis (TB) is responsible for the largest number of cases, while necrotizing sarcoidosis is generally considered a rare and easily distinguishable disease substantially based on histological features. However, this entity has become a viable diagnosis in the absence of mycobacteria isolation or when a remarkable clinical improvement cannot be achieved with the combination of anti-TB drugs at full dosage...

BACKGROUND: Central nervous system tuberculosis (CNS-TB) may be fatal even with treatment. Neutrophils are the key mediators of TB immunopathology, and raised CSF matrix metalloproteinase-9 (MMP-9) which correlates to neutrophil count in CNS-TB is associated with neurological deficit and death. The mechanisms by which neutrophils drive TB-associated CNS matrix destruction are not clearly defined. METHODS: Human brain biopsies with histologically proven CNS-TB were stained for neutrophils, neutrophil elastase, and MMP-9...

INTRODUCTION: It is universally agreed that screening for latent tuberculosis infection prior to biologic therapy is necessary, especially in endemic areas such as Hong Kong. There are still, however, controversies regarding how best to accomplish this task. The tuberculin skin test has been the routine screening tool for latent tuberculosis infection in Hong Kong for the past decade although accuracy is far from perfect, especially in patients who have been vaccinated with Bacillus Calmette-Guérin, who are immunocompromised, or who have atypical mycobacterium infection...

BACKGROUND: Postmortem imaging (PMI) refers to the imaging of cadavers by computed tomography (CT) and/or magnetic resonance imaging (MRI). Three cases of cerebral infarctions that were not found during life but were newly recognized on PMI and were associated with severe systemic infections are presented. CASE PRESENTATIONS: An 81-year-old woman with a pacemaker and slightly impaired liver function presented with fever. Imaging suggested interstitial pneumonia and an iliopsoas abscess, and blood tests showed liver dysfunction and disseminated intravascular coagulation (DIC)...

AIMS AND OBJECTIVES: Extrapulmonary disease accounts for a significant proportion of all cases of tuberculosis (TB) in endemic areas. With increasing prevalence of human immunodeficiency virus (HIV), the case numbers are rising; extrapulmonary involvement can be seen in >50% of patients with concurrent AIDS and TB. In both HIV-positive and HIV-negative cases, due to diagnostic difficulties, extrapulmonary disease is often recognized late and, hence, although completely curable in many cases, as far as bacterial eradication is concerned, is not without consequence...

REVIEW
J G Garweg
Ocular involvement in sarcoidosis is present in up to one third of patients and is frequently manifested before the underlying systemic disease has been diagnosed. With a view to the therapeutic consequences an early diagnosis of the underlying disease is advantageous. In cases of visual loss early diagnostic measures include invasive procedures, such as ultrasound-guided bronchoalveolar lavage and transbronchial biopsy, if nodular conjunctival or cutaneous manifestations which would confirm the diagnosis are not present...
