In an uncontrolled study in Zambia, HIV-infected patients treated <strong>for</strong><br />

tuberculosis who had adjunct therapy with corticosteroids developed herpes<br />

zoster <strong>and</strong> Kaposi’s sarcoma significantly more often, while generalized<br />

lymphadenopathy improved. 924<br />

The routine use of corticosteroids as adjunct therapy <strong>for</strong> pulmonary<br />

tuberculosis cannot, there<strong>for</strong>e, be recommended. In addition to the multitude<br />

of known adverse effects directly related to steroid use, in tropical<br />

countries parasitic infestation is common <strong>and</strong> corticosteroids in such patients<br />

may precipitate dissemination 925 <strong>and</strong> abscesses. 926<br />

The indication <strong>for</strong> the use of corticosteroids in pulmonary tuberculosis<br />

should be restricted to patients so seriously ill that their prognosis is judged<br />

to be very poor <strong>and</strong> thus the steroids are potentially life-saving. 7,927<br />

Pleural tuberculosis<br />

A number of studies have been reported evaluating the use of corticosteroids<br />

in pleural tuberculosis. 928-937 Not all of the studies were conducted<br />

with the same rigor <strong>and</strong> only eight provide sufficient in<strong>for</strong>mation <strong>for</strong> an<br />

adequate evaluation. 928-933,936,937<br />

Most studies showed a more rapid resolution of effusions in those<br />

given corticosteroids. In the studies that evaluated residual pleural thickening<br />

as the crucial endpoint, three found less thickening in the steroid<br />

treated group 930-932 <strong>and</strong> two found no difference between placebo <strong>and</strong> steroid<br />

treated groups. 936,937<br />

From these studies it would appear that the value of corticosteroids in<br />

the treatment of pleural effusion is doubtful. Weighted against the possible<br />

adverse effects, steroids should probably not be routinely used in tuberculous<br />

pleural effusion.<br />

Pericardial tuberculosis<br />

The efficacy of corticosteroid therapy <strong>for</strong> tuberculous pericarditis may differ<br />

<strong>for</strong> the different physiological stages of the disease (effusive, effusiveconstrictive,<br />

<strong>and</strong> constrictive). 908 Several retrospective studies fail to address<br />

these points <strong>and</strong> lack well-defined endpoints. 938,939 In a retrospective study<br />

addressing the critical issue of stage of disease, patients on corticosteroids<br />
