[Brain abscess in the course of miliary tuberculosis: a case report and review of the literature].

The frequency of tuberculous cerebral involvement associated with miliary tuberculosis is not well known; some authors have evaluated it at around 22%. We report the case of a 43-year-old man hospitalised in the pulmonology department with bacillary positive miliary tuberculosis. On the 26th day of antituberculosis treatment he complained of frontal headaches, with impairment in visual acuity. Examination of the optic fundus showed bilateral papillary oedema. Cerebral computed tomography showed diffuse rounded lesions with significant oedema. Antituberculosis chemotherapy was supplemented with steroid treatment. Clinical and radiological progress was good.

Miliary tuberculosis in Edinburgh--a comparison between 1984-1992 and 1954-1967.

We have reviewed the records of 29 patients notified with miliary tuberculosis in Edinburgh from 1984 to 1992 and compared our findings with those for the 40 patients previously reported in Edinburgh from 1954 to 1967. The incidence of miliary tuberculosis has not changed. Respiratory symptoms of cough and dyspnoea were commoner in 1984-1992 (P < 0.001) perhaps reflecting the increase in mean age at presentation (73.5 vs. 59.4 years; P < 0.001). Mortality was 50% in 1984-1992, significantly higher (P < 0.05) than the 25% recorded in 1954-1967. Forty percent of cases in both time periods were of cryptic miliary disease. The diagnosis of cryptic disease tended to be made more often post-mortem and less often by a trial of anti-tuberculosis chemotherapy in 1984-1992. Our findings emphasize the current poor outcome associated with a diagnosis of miliary tuberculosis. It is important to consider this diagnosis in elderly patients with unexplained pyrexia and implement a trial of specific anti-tuberculosis chemotherapy to confirm it.

Miliary tuberculosis: rapid diagnosis, hematologic abnormalities, and outcome in 109 treated adults.

PURPOSE: The purpose of this study was to determine the clinical and laboratory characteristics, diagnostic methods, and prognostic variables in adults treated for miliary tuberculosis in the rifampicin era. PATIENTS AND METHODS: Computerized records of our community-based university teaching hospital over a 10-year period (1978 to 1987) were analyzed. A total of 109 patients were identified, including 12 who did not have miliary nodules on the chest radiograph (all of whom were shown to have hematogenous dissemination). Predisposing conditions were present in 46 patients. RESULTS: Clinical features were similar to those of previously reported series. Hematologic abnormalities were common: leukopenia (less than 4 x 10(9)/L) was present in 16 of 107 patients (15%), thrombocytopenia (less than 150 x 10(9)/L) in 24 of 104 (23%), and lymphopenia (less than 1.5 x 10(9)/L) in 82 of 94 (87%). Pancytopenia was found in six patients, three of whom recovered. Disseminated intravascular coagulation occurred in four patients, all of whom died. Adenosine deaminase levels were elevated in only seven of 11 serosal exudates and in seven of 12 samples of abnormal cerebrospinal fluid. Fiberoptic bronchoscopy was diagnostic in 44 of 51 patients (86%), bone marrow examination in 19 of 22 (86%), and liver biopsy in all 10 patients. Twenty-six patients (24%) died of miliary tuberculosis a median of 6 days after starting treatment. Survivors were followed up for a median of 51 weeks. Stepwise logistic regression identified aged (greater than 60 years), lymphopenia, thrombocytopenia, hypoalbuminemia, elevated transaminase levels, and treatment delay as independent predictors of mortality. CONCLUSIONS: Miliary tuberculosis commonly causes hematologic derangements, some of which are helpful prognostically. Fiberoptic bronchoscopy compares favorably to liver and bone marrow biopsy in sputum smear-negative cases. Mortality remains high and treatment should be begun as soon as the diagnosis is suspected.

A rare complication of miliary tuberculosis: intestinal perforation.

Small bowel perforation is a rare complication of miliary tuberculosis. We report the case of a 21-year old patient who developed a small bowel perforation 70 days after the initiation of adequate tuberculosis treatment. We also present a review of the literature.

[Cryptic miliary tuberculosis. Two case-reports (author's transl)].

The term cryptic miliary tuberculosis designates a particular form of hematogenous tuberculosis in which the usual diagnostic criteria, especially the roentgenographic ones, are lacking. Two cases are reported. Initial clinical manifestations were prolonged fever, poor general condition, low blood pressure, low serum sodium, mild hepatic biological disorders, and myocarditis. No other radiological or biological features, suggestive of tuberculosis were found. In the first patient, the various visceral tuberculous localizations occurred under specific treatment, although the latter was otherwise effective. In the second patient, they were identified by pathological examination. The incidence of these occult forms of tuberculosis, where diagnosis is often established too late, and sometimes only postmortem, is not negligible. This possibility must be borne in mind in severe infectious conditions without obvious etiology, particularly when the following features are present : inadequate secretion of ADH, which often indicates latent encephalitic and meningitic involvement where CSF anomalies may be incomplete or lacking ; leucopenia or pancytopenia ; biological hepatic anomalies ; exceptionally, such as in the two cases described, cardiac involvement. Among diagnostic procedures, liver biopsy is of the utmost importance. Mere diagnostic presumption is sufficient to warrant initiation of antituberculous therapy. This ensures survival and, paradoxically, allows delayed overt clinical manifestations to develop.

Miliary tuberculosis in a high prevalence area of the U.K.: Blackburn 1978-1993.

Thirty-nine cases of military tuberculosis treated between 1978-1993 in a district with a high incidence of tuberculosis are reported. Twenty-eight patients were of Indian Subcontinent (ISC) ethnic origin, 10 patients were Caucasian and one patient was Chinese. Mortality at 10% in both Caucasian (chi2 4.94; 0.05 > P > 0.01) and ISC patients (chi2 10.22; 0.001 > P) were significantly lower than in a recently reported series from Edinburgh, as was the proportion of post mortem diagnoses of miliary tuberculosis (chi2 6.35; 0.02 > P > 0.01). Both the rate of miliary tuberculosis and the average age at diagnosis in Caucasian patients were lower than in the Edinburgh series suggesting that miliary tuberculosis could be under-diagnosed in the elderly Caucasian population in the Blackburn district. The better outcome of those diagnosed in life may be partly due to heightened awareness of tuberculosis locally and partly due to treatment by a centralized tuberculosis service.

[Acute respiratory distress syndrome and pancytopenia during miliary tuberculosis in a HIV positive patient].

Acute respiratory distress syndrome (ARDS) is a rare but severe complication of miliary tuberculosis, which may occur even under antituberculous therapy. Even with adequate treatment, its mortality is close to 70%, and if associated with pancytopenia, it may reach 100%. Underlying diseases, delayed diagnosis and additional complications are factors of poor prognosis. We report a case of a patient infected with the human immunodeficiency virus who experienced pancytopenia and ARDS associated with miliary tuberculosis. The patient recovered under antituberculous chemotherapy.

Miliary tuberculosis in a patient with Epstein-Barr virus-associated angioimmunoblastic lymphadenopathy.

A 74-year-old woman developed angioimmunoblastic lymphadenopathy (AILD) with involvement of intra-abdominal and retroperitoneal lymph nodes. Southern blot analysis showed germline configuration of the JH genes and an oligoclonal pattern of the TcR beta genes. The immunoblasts were of B-cell phenotype and often expressed the CD30 antigen and the latent membrane protein 1 (LMP1) oncogene. Six nonsilent point mutations were identified near the 3' end of the LMP1 gene, leading to a cluster of six amino acid changes within a protein domain needed for maximal NF-kappa B stimulation. After a clinical remission of 8 months the patient relapsed with generalized lymphadenopathy and died secondary to tuberculosis. The oligoclonal rearrangements of the TcR beta genes may reflect an unsuccessful cellular immune response to Mycobacterium tuberculosis or an HLA-restricted T-cell response to B-immunoblasts expressing mutated viral antigens. A positive percutaneous tuberculin test observed 6 months prior to the onset of AILD is in favor of the first possibility.

Haematological changes associated with miliary tuberculosis of the bone marrow.

The peripheral blood and bone marrow findings in 25 patients found to have tuberculous granulomata on bone marrow examination were examined to determine whether specific haematological findings are associated with tuberculous infiltration of the bone marrow. All the patients had one abnormality or more on their full blood count. The presence of a peripheral lymphopaenia was the single factor common to all 25 patients studied. The peripheral lymphopaenia was only associated with bone marrow lymphopaenia in 14% of patients. Other findings of note were an association of peripheral monocytopaenia and absence of giant cells in the granulomata, and decreased iron stores in almost a third of the total number of patients. The relevance of the lymphopaenia, monocytopaenia and decreased iron stores are discussed and we propose that the absence of a peripheral lymphopaenia makes it very unlikely that there will be tuberculous localization in the bone marrow.
