Section snippets
Materials and Methods
All reports dealing with the long-term course and prognosis ofsarcoidosis originating in large, outpatient adult practices in Westerncountries, unsorted by chronicity, classified according to stage, andidentified in a MEDLINE search and bibliographic survey of publicationsin the English language from 1960 through 2000, were reviewed andallocated by origin in RS or PS. The search terms employed weresarcoidosis AND course, AND prognosis, AND outcome. Compendia based onhospitalized patients were
Meta-analysis and Review
Ten reports fulfilling the inclusion criteria wereidentified45678910111213; they are summarized in Tables 1,2.
Discussion
Imprecision of the available data, in combination with varyingmeans of data presentation, constitute the major limitation of thisstudy. Cumulative mortality is an imprecise estimate of mortality rate(which was not supplied), neither the dose or duration of CST wasprovided, no study supplied details of physiologic impairment, and onlyone study10 detailed the radiographic extent of disease.Patient age and duration of follow-up were supplied by differentauthors in noncomparable formats: range,
Conclusions
(1) Sarcoidosis mortality representative of patients who arelikely to be encountered by community physicians in western countriesis 0.5%, less than one tenth of that reported from RS; (2) althoughethnic differences strongly influence the incidence and clinicalmanifestations of sarcoidosis, they have little appreciable influenceon its mortality; and (3) the possibility that a lower threshold foradministering CST is associated with an increased mortality risk,beyond the selection effect that
