Secondary immunodeficiency in miliary tuberculosis.

Cell-mediated immune response was investigated in fifteen patients with miliary tuberculosis. Delayed hypersensitivity skin test with "recall" antigens PPD and SKSD was positive in two and one patients respectively. An irritant dose of DNCB failed to induce non-specific inflammatory response in the skin of thirteen patients and the same patients also did not develop contact sensitivity to DNCB. Leucocyte migration test in the presence of Mycobacterium tuberculosis was also negative in eight of eleven patients studied. The proportion of E rosette-forming cells was found to be significantly depressed, though the proportion of EAC rosette-forming cells did not show any abnormality. On repeat skin tests in five patients after 3 months of chemotherapy and clinical improvement four showed a positive PPD and DNCB response. It was concluded that there is a marked degree of secondary immunodeficiency in miliary tuberculosis.

Miliary tuberculosis: epidemiology, clinical manifestations, diagnosis, and outcome.

During the early 1970s, attention was called to the changing demographics and poor prognosis of patients with miliary tuberculosis. Thirty-eight non-AIDS patients with miliary tuberculosis seen since 1975 are reviewed. Their average age was 60 years. Two-thirds of the patients had comorbid conditions. Presenting symptoms were nonspecific; fever, anorexia, sweats, and weight loss were the most frequent. Fever, tachypnea, rales, and altered mental status were the most commonly associated signs. Chest radiographs often showed miliary disease, but the remainder of the laboratory abnormalities were nonspecific. Seventy-six percent of sputum cultures, 75% of gastric aspirate cultures, 59% of urine cultures, and 54% of bronchial washings were positive for Mycobacterium tuberculosis. Biopsy specimens, including those obtained by transbronchial biopsy, were frequently abnormal histologically but were rarely culture-positive. Mortality attributable to miliary tuberculosis was 21%. Risk factors for death included female sex and altered mental status. No patient treated initially with a regimen that included streptomycin died whereas 21% of those treated with other regimens died. These data confirm and extend the results of earlier studies and suggest that miliary tuberculosis is a disease of the elderly and immunocompromised and is associated with significant morbidity and mortality. A high index of suspicion and diagnostic persistence are required for diagnosis.

Tuberculous subcutaneous abscesses developing during miliary tuberculosis therapy.

Although rare, paradoxical subcutaneous abscesses may develop during appropriate treatment of miliary tuberculosis. While the pathogenesis of this phenomenon is not clear, some theories have been postulated. A case of a 37-y-old woman diagnosed as having miliary tuberculosis who developed subcutaneous abscesses within the 5 months of antituberculous treatment is described and all 6 similar cases published in English from 1954 to 1999 are discussed.

The pathogenesis of pulmonary and miliary tuberculosis.

Tuberculosis is spread from human to human by airborne transmission; it is not a highly infectious disease. Primary infection remits in 90% of cases and is progressive in the remainder; it is accompanied by lymphohematogenous seeding of many organs, and reactivation may occur as early as three months or many years after initial infection. Primary infection generally confers immunity from subsequent reinfection. The risk of reactivation of tuberculosis is greatest in the year after infection, declining sharply thereafter for most patients. Acute miliary tuberculosis has a distinctive pathogenesis that is different from localized postprimary disease. Miliary tuberculosis may appear in a patient with a normal chest roentgenogram; even in patients with abnormal chest roentgenograms, sputum cultures for acid-fast organisms may be negative. Transbronchial biopsy is the preferred method of diagnosis and prompt initiation of treatment is essential.

Miliary tuberculosis in children. A clinical review.

Eighty cases of miliary tuberculosis admitted to our hospital between January 1981 and December 1984 were reviewed. The age of the patients ranged from 3 months to 12 years, with an average of 2 years 2 months (26.5 months). Nine cases (11.25%) died during hospitalization due to the severe condition at the time of admission. Only 8 patients (10%) were in good nutritional condition. Seventy-two patients (90%) had been visiting the primary health care clinic for several times since 2-3 months but were never diagnosed as suffering from tuberculosis. Fever or recurrent fever were found in 78 cases (97.5%), anorexia in 65 cases (81.3%), chronic and/or recurrent cough in 72 cases (90%) and malaise in 43 (53.8%). Forty-one (51.3%) denied the presence of a close contact with source of infection. Hepatomegaly was found in 44 cases (55%), 19 (23.8%) of which were associated with splenomegaly. Choroidal tubercle was found in 4 cases; 1 case with coxitis, 1 with brain tuberculoma, 1 with ascites, 1 with endobronchitis and 1 with hepatitis. Forty-three (53.8%) were tuberculin negatives, 24 of which become positives after treatment. Fourteen cases had BCG scar. History of measles was found in 21 cases. Children with longterm and recurrent fever, anorexia, decrease of body weight and recurrent cough should be suspected of having TB thus enabling to get an early diagnosis.

[Course and outcome of miliary tuberculosis in adults at present].

Study of the clinical features of the course of miliary tuberculosis in 19 patients between the ages of 16 and 72 years has demonstrated that it begins more commonly with extrapulmonary symptoms and has quite diverse manifestations which makes diagnosis difficult and calls for a more accurate analysis of the clinical manifestations of the disease.

[Miliary tuberculosis in 27 children].

In the course of 3 1/2 years, 27 children with miliary tuberculosis were seen at the Hospital Infantil Lorencita Villegas de Santos in Bogotá, Columbia. Twenty-six percent of cases were infants under 12 months of age. Typical clinical cases were malnourished patients with impairment of their general condition, light respiratory stress or neurologic meningoencephalic involvement and febrile syndrome having a high contact index with tuberculous relatives. Some of them were undergoing measles or whooping cough convalescence. The chest X-ray showed micronodular infiltration and some cases, with hiliar adenomegaly, effusion or caverns. The liver percutaneous biopsy was of great help. The isolation of the bacillus from exudates was difficult to achieve. Tuberculin test was positive only in 30%. Cause of death: infiltration of central nervous system.

Miliary tuberculosis presenting as skin lesions in a patient with acquired immunodeficiency syndrome.

Acute miliary tuberculosis of the skin is an extremely rare infection that occurs in immunocompromised persons. We report an intravenous drug abuser with human immunodeficiency virus infection in whom erythematous papules developed on the trunk and proximal aspect of the extremities. Visceral lesions of unsuspected miliary tuberculosis were discovered at autopsy, and the cutaneous papules were found to contain Mycobacterium tuberculosis. This is the first reported case of this cutaneous infection in a patient with the acquired immunodeficiency syndrome.

About an unusual systemic disorder: report of a cryptic miliary tuberculosis.

We report here the case of a young Chinese woman with cryptic miliary tuberculosis associated with acute hepatitis, pancytopenia, biological disseminated intravascular coagulation (DIC), and hyponatremia. Following the introduction of a classic tuberculostatic treatment, her general status quickly improved. After an extensive review of the literature, this is, to the best of our knowledge, the first case of cryptogenic miliary tuberculosis with all its cumulative complications.

Miliary tuberculosis: unusual cause of abdominal pain in pregnancy.

We have described a case of miliary tuberculosis, with symptoms primarily due to hepatic involvement during pregnancy. Liver biopsy showed granulomatous hepatitis, and subsequent cultures of sputum, urine, and gastric aspirate were positive for Mycobacterium tuberculosis. Although this patient was seronegative for HIV, an increased incidence of extrapulmonary and disseminated tuberculous infection has recently been noted in patients with HIV infection. Given the increasing incidence of HIV in the general population, we may therefore anticipate a corresponding rise in the incidence of extrapulmonary tuberculosis. Since an increasing number of gravidas will be immunocompromised by HIV infection, renewal of knowledge regarding diagnosis of miliary tuberculosis in pregnancy is valuable.
