Generalized tuberculosis in the acquired immune deficiency syndrome.

OBJECTIVE: Generalized, or hematogenously disseminated, tuberculosis (TB) in patients with the acquired immune deficiency syndrome (AIDS) has been associated with a high incidence of cases remaining undiagnosed until postmortem. To better characterize generalized TB in the setting of AIDS, this report describes the clinical, laboratory, radiologic, and pathologic features of 20 fatal cases. DESIGN: The medical records, autopsy protocols, and histologic material from patients with AIDS and concomitant TB were reviewed. All patients were autopsied at a tertiary care medical center during the years 1985-1997. RESULTS: In 50% of our 20 cases, diagnosis was not made until postmortem. Signs and symptoms were few, including the absence of fever (temperature > or = 38 degrees C) in 55% of patients. Consistent laboratory abnormalities of a nonspecific nature were limited to hyponatremia (sodium <135 mmol/L) in 60%. Both peripheral and deep (thoracic and abdominal) lymphadenopathy, unusual in adults with TB, occurred in 45% and 95% of cases, respectively. In contrast to previous reports, all of the 6 cases of tuberculous meningitis presented as acute meningitis with a predominance of neutrophils in cerebrospinal fluid. Necrotizing encephalitis with extension of the acute inflammation into the superficial cortex was seen in all cases and tuberculous brain abscesses occurred in 50% of cases, a higher frequency than previously reported. Despite lung involvement in 90% of the cases, 33% of chest radiographs were interpreted as normal and disseminated mycobacterial disease was not suggested in the radiograph report in any of the other cases. Soft tissue abscesses in uncharacteristic locations such as the neck, mediastinum, and perirectal area occurred in these patients. Histologically, 95% of organs sampled showed inflammatory foci characterized by extensive necrosis with numerous neutrophils and/or karyorrhectic debris, numerous acid-fast bacilli, few or no epithelioid histiocytes, and no Langhans giant cells. CONCLUSION: Clinically and pathologically, generalized TB in the setting of AIDS is characterized by either unusual features or a lack of the typical features described for generalized TB in patients who do not have AIDS. This absence of classic features contributes to the high incidence of cases that remain undiagnosed until postmortem examination.

The role of ultrasonography in the detection of extrapulmonary tuberculosis in patients with acquired immunodeficiency syndrome (AIDS).

Three cases of extrapulmonary tuberculosis are presented. Retroperitoneal and periportal adenopathy were the major manifestation of the disease detected by ultrasonography in all three cases. All of the patients were subsequently diagnosed as having acquired immunodeficiency syndrome (AIDS). The lymphohematogenous dissemination of the disease and the diagnostic role of ultrasonography are discussed.

Gallium-67 citrate scan in extrapulmonary tuberculosis.

AIM: Whole-body gallium scan was performed to evaluate the usefulness of gallium scan for detecting extrapulmonary tuberculosis (TB) lesions. METHODS: Thirty-seven patients with extrapulmonary TB were included in this study. Four patients were found to have two lesions. Totally, 41 lesions were identified, including 19 TB arthritis, 8 spinal TB, 5 TB meningitis, 3 TB lymphadenopathy, 2 TB pericarditis, 1 TB peritonitis, 1 intestinal TB, 1 skin TB and 1 renal TB. RESULTS: Of the 41 extrapulmonary TB lesions, gallium scan detected 32 lesions with a sensitivity of 78%. All the patients with TB meningitis showed negative gallium scan. When the five cases of TB meningitis were excluded, the detection sensitivity of gallium scan increased to 88.9% (32/36). CONCLUSION: Our data revealed that gallium scan is a convenient and useful method for evaluating extrapulmonary TB lesions other than TB meningitis. We suggest that gallium scan be included in the clinical routine for patients with suspected extrapulmonary TB.

Perforation due to ileocaecal tuberculosis.

A 40-year-old male patient was admitted in the Intensive Care Unit with complicated pulmonary tuberculosis. After 4 days he developed an acute abdomen with free air as demonstrated on plain abdominal films. A laparotomy was performed and an ileal perforation was found, located just before the ileocaecal valve. A right hemicolectomy was carried out and the resected specimen was send for further patho-anatomical examination. Our suspicion of ileocaecal perforation due to tuberculosis was confirmed. Despite further extensive medical treatment, the patient died 15 days after admission to the hospital. At autopsy, the cause of death was confirmed as being due to fulminant pulmonary tuberculosis.

[The diagnosis of abdominal tuberculosis in military medical and prophylactic institutions].

Abdominal tuberculosis constitutes 0.5-2% in the general structure of the disease, nevertheless it requires special methods of treatment. The authors draw the rules of diagnosis at the early stages of the disease development on the base of 55 patients' case records. They also present a list the most important research projects on chronic and acute abdominal cases.

Severe malnutrition due to subtle neurologic deficits and epilepsy: report of three cases.

In southern and eastern Africa, where approximately eight per cent of households lack access to adequate food, children suffering from chronic infections such as tuberculosis, gastrointestinal parasites and human immunodeficiency virus, often present with severe protein energy malnutrition. Three cases are described of children presenting to Chikankata Salvation Army Hospital who required hospitalization and urgent feeding due to PEM. No underlying aetiology for their life-threatening PEM could initially be identified and they were all observed to gain weight while in the intensive feeding unit. After discharge, each re-presented with recurrent failure-to-thrive and were found to have subtle neurologic deficits and underlying epilepsy. Epilepsy and developmental disabilities should be considered in patients with PEM for whom other aetiologies cannot be identified.

Surgical presentation of abdominal tuberculosis: a protean disease.

BACKGROUND/AIMS: The incidence of tuberculosis is rising again in the Western world, due to the emergence of new groups of patients at risk. This paper intends to describe the various patterns of surgical presentation of abdominal tuberculosis in an industrialized country. METHODOLOGY: A retrospective study was made of all patients admitted to our surgical institution, and in whom a diagnosis of abdominal tuberculosis was established. Eleven patients were identified. Ten of them were migrants from countries endemic for tuberculosis. RESULTS: Six patients presented with acute abdominal pain (3 in right lower quadrant) and had surgery in emergency. Two patients had elective surgery for diagnostic purposes. Two patients underwent other invasive diagnostic and/or therapeutic procedures. One patient was treated conservatively. Unusual presentations included 2 patients with periportal lymphadenitis and compressive features on the main bile duct and/or the portal vein, and 1 patient with acute duodenal tuberculous perforation. The main localization of disease was lymph nodes for 5 patients, intestinal for 4 and peritoneal for 2. CONCLUSIONS: Surgeons must be aware of the wide clinical spectrum of abdominal tuberculosis and have a high index of suspicion when confronted with patients from an endemic area and presenting with unclear abdominal symptoms.

[Tuberculosis in immigrants].

Three cases of tuberculosis in immigrants are described here. The manifestations of tuberculosis in this group are often different from those seen in Danes--in casu tuberculosis of the lymph nodes, skin, bone, and intestines. Diagnosis is difficult, as Danish doctors are not familiar with the clinical picture. Language problems are common and often necessitate the presence of an interpreter. Immigrants tend to move around without notifying the responsible doctor and the resources needed to find them may not be readily available. These factors may cause a considerable delay--from months to years--in the diagnosis and treatment. Doctors examining immigrants from Africa and Asia should be aware of tuberculosis as a possible cause of disease. Secretion and biopsies from fistulae, chronic ulcerations, lymph nodes, and abscesses should always be cultured for Mycobacterium tuberculosis. The Mantoux reaction can be misleadingly negative in patients suffering from severe tuberculosis. Identification of Mycobacterium tuberculosis is not necessary for treatment--that decision is made on the clinical picture. On the other hand material for a bacteriological diagnosis should always be obtained, because of possible resistance problems.

Tuberculous enteritis. Review of a protean disease.

Prior to the advent of antituberculosis drugs, at least 70% of patients with far advanced pulmonary tuberculosis had tuberculous enteritis. Despite the effectiveness of drug therapy, overt cases of tuberculous enteritis occur in the United States and particularly among immigrants from endemic areas. Clinicians often forget to consider this entity. The patient may have no or minimal abdominal complaints. Vague abdominal distress, anorexia and weight loss can be overlooked because of the extensive pulmonary exudative or cavitary disease. Even after an enteric lesion is identified, often it is mistaken for other entities, particularly neoplasm or Crohn's disease. Obviously, the diagnosis is difficult but certain radiological criteria can be indicative of the disease. This report demonstrates the protean manifestations of this entity, the complications which occur despite drug therapy and the need for continued awareness of its existence.
