Authors report the first autopsy case of acquired immune deficiency syndrome in Korea. The patient was a 26 years old Korean male who died of respiratory failure due to mixed pulmonary infections. He had history of homosexual contacts with partners of both domestic and foreign nationalities. Initial presentation was unexplained fever for two months. Serological test and western blot test for anti-HIV were positive and T-cell subset analysis revealed T3/T4/T8 to be 73/8/67%. Pulmonary tuberculosis with mediastinal lymphadenopathy and esophagonadal fistula and oral candidiasis were presented. Respiratory infection progressed gradually and he died seven months after the initial symptom. Autopsy findings were generalized severe lymphoid cell depletion, especially of T-cell population and mixed pulmonary infections with Pneumocystis carinii and cytomegalovirus (CMV). The CMV infection involved lungs and adrenals. Oral candidiasis was also demonstrated.

OBJECTIVEMost of Endobronchial tuberculosis (EBTB) of children is caused by the bronchial erosion from the scrofula close to the bronchus. Due to its complicated mechanism, pediatricians have limited knowledge on the endobronchial tuberculosis, which makes the misdiagnosis rate high. This work explored the clinical features and diagnostic methods of endobronchial tuberculosis (EBTB), to improve the understanding of this disease.

METHODA total of 102 cases with endobronchial tuberculosis (EBTB) were investigated by analyzing clinical and bronchoscopic features, imaging manifestation, PPD results and etiological examination; 71 cases were male, 33 were female, the youngest was 4 months old, and the oldest was 10 years old. The patients were treated in the fourth ward of the Department of Internal Medicine, Beijing Children's Hospital, Capital Medical University.

RESULTOf the 102 cases, 71 (69.6 percent) were infants and young children. (1) Age and clinical presentation: Infants and young children were more common, the main clinical manifestations were fever and cough, physical examination may find decreased breath sounds, wet and dry rale and wheezing. (2) In 81 cases who received CT there was bronchial obstruction, in 43 cases there were simultaneous manifestations of primary pulmonary tuberculosis (mediastinal and hilar lymph node enlargement and/or pulmonary consolidation), 21 cases had only manifestations of primary tuberculo. (3) The results of PPD: the positive rate was 95%. (4) Bronchoscopic feature: presence of mucosal swelling, caseous necrosis, bronchial stenosis/extrabronchial compression, granulomatous lesions and lymph node bronchial fistula. (5) Bacteriologic results: 21 patients were bacteriologically positive.

CONCLUSIONBronchial tuberculosis was more common in infants and young children, their major clinical manifestations were fever, cough, common findings on lung imaging was mediastinal and hilar lymph node enlargement and/or pulmonary consolidation, bronchial obstruction should be considered manifestations of bronchial tuberculosis, positive PPD should support the clinical diagnosis. Diagnosis can be confirmed by positive bacteriological tests.

Hemophagocytic lymphohistiocytosis (HLH) was a life-threatening syndrome due to the uncontrolled immune activation of cytotoxic T lymphocytes, natural killer (NK) cells, and macrophages. HLH is characterized by primary and secondary causes, the early diagnosis and treatment of patients are closely related to the prognosis and clinical outcome of patients. The clinical presentation is variable but mostly includes prolonged fever, splenomegaly, coagulopathy, hypertriglyceridemia, and hemophagocytosis, none of them is specific and particular for HLH. Tuberculosis (TB) infection is one of the causes of HLH. HLH caused by TB is very rare clinically, but it has a high mortality. For patients with fever of unknown origin, HLH-related clinical manifestations sometimes present before the final diagnosis of TB, and HLH is associated with the most significant mortality rate. This article is mainly about a 28-year-old patient with HLH who suffered from severe TB infection. The patient attended a hospital with a history of 2 months of prolonged fever, 10 days booger and subcutaneous hemorrhage in lower limbs. Before this, he was in good health and denied any history of tuberculosis exposure. Combined with relevant laboratory test results (such as splenomegaly, hemoglobin, platelet count, and hypertriglyceridemia) and clinical manifestations (e.g. fever), the patient was diagnosed with hemophagocytic lymphohistiocytosis, but the etiology of HLH remained to be determined. To confirm the etiology, the patient was asked about the relevant medical history (intermittent low back pain) and was performed chest CT scan, bone marrow biopsy, and fundus photography. Finally, he was diagnosed with hemophagocytic lymphohistiocytosis caused by hematogenous disseminated pulmonary tuberculosis. In response to this, intravenous methylprednisolone and anti-tuberculosis treatment (isoniazid, pyrazinamide, moxifloxacin, and amikacin) were administered to the patient. After more than a month of treatment, the patient recovered from HLH caused by severe TB infection. Therefore, this case suggests that we should be vigilant to the patient who admitted to the hospital with fever for unknown reasons, to diagnose HLH as early as possible and clarify its cause, then perform interventions and treatment, especially HLH secondary to tuberculosis. Also, cases of atypical TB and severe TB should be carefully monitored to achieve early diagnosis and early intervention.

Pulmonary tuberculosis (PTB) is a common infectious disease worldwide. However, mediastinal tuberculous lymphadenitis complicated by oesophageal involvement and oesophago-respiratory fistula is now uncommon due to improved anti-tuberculous regimes and better general awareness. The overall incidence of acquired oesophago-respiratory fistula due to infection is low, and therefore, the lesion is not often a frontrunner in differential diagnosis. Still, tuberculous oesophago-respiratory fistulae can potentially occur in patients with retroviral disease, as they tend to have atypical and more virulent manifestations. In this study, we report the case of multiple oesophago-respiratory fistulae in a patient with PTB and retroviral disease, and highlight the computed tomography features of these lesions as an atypical presentation of PTB in retroviral disease. Clinicians should suspect oesophago-respiratory fistulae if patients present with Ono’s sign, and remain particularly vigilant for patients with underlying PTB and retroviral disease, as early diagnosis and treatment could help to reduce mortality.

Patients with idiopathic pulmonary fibrosis (IPF) have an increased risk for developing tuberculosis (TB). However, no studies have been reported regarding the development of nontuberculous mycobacterium (NTM) lung disease (NTMLD). We reviewed 795 patients with IPF from five university hospitals who were diagnosed by histological or radio-clinical criteria. In the 795 patients with IPF, pulmonary infections with mycobacterium tuberculosis (MTB) and NTM were found in 35 (4.4%) and 16 patients (2.0%), respectively, which was a higher frequency than that found in the general population. TB was more common in patients treated with immunosuppressants than in those who did not receive immunosuppressants (2.6% vs 1.4%, P = 0.12). Among the IPF patients who had mycobacterial infections,immunosuppressant users developed TB or NTMLD within 1 yr after treatment with immunosuppressants,while those occurred later than 2 yr after diagnosis of IPF in the subjects that did not receive immunosuppressants. Among 51 IPF patients who had mycobacterial infections, 9 (18%) died during follow-up. Of these, three died due to progression of pulmonary tuberculosis. TB and NTMLD is relatively common in patients with IPF in Korea and may be fatal in some groups. Careful evaluation of TB and NTMLD is necessary not only for immunosuppressant users, but also for nonusers with IPF.
